Description

Technical Field

[0001] This application belongs to the field of cargo conveying technology, and more specifically, relates to a chute and cargo conveying mechanism. Background Technology

[0002] With the continuous updating and development of modern information technology, long-distance transport / delivery of goods relying on information technology has become a core mode of logistics transportation. Generally, during the process of consolidation or sorting of goods at the point of origin, transit point, or destination, goods are transferred through fully or semi-automatic assembly line equipment, such as using conveyor belts or manual methods to transfer goods into chutes.

[0003] The chute has a certain length, which allows the inner wall of the chute to confine and guide the goods along its length. The chute also has a certain inclination along the direction of gravity, allowing the goods to use their own gravitational potential energy to slide out of the chute along its length. Thus, under the combined effect of the chute's structure and the goods' own gravitational potential energy, the goods enter the chute from its higher end and exit from its lower end.

[0004] However, different goods differ in volume, density, material, or construction; they also differ in weight; and they enter the chute from the higher end with different initial velocities. In other words, different goods possess different gravitational potential energy within the chute, different frictional forces between the goods and the chute's inner wall, and different kinetic energies. Ultimately, this leads to different sliding trajectories for the goods within the chute, and also increases the risk that some goods may not be able to slide out from the lower end of the chute.

[0005] Based on the different weights and volumes of various goods, the goods are categorized into low-energy, medium-energy, and high-energy goods by the varying pressure they exert on the chute. Here, energy can refer to the energy possessed by the goods during movement, primarily including kinetic and potential energy, a physical quantity that measures the work capacity of the goods due to their motion and relative position. Alternatively, energy can refer to the energy density of the goods, which is positively correlated with their density. Different goods densities exert different pressures on the chute, thus classifying the goods based on these pressure differences.

[0006] Low-energy goods are typically small in size and lightweight, entering the chute from the higher port with a lower initial velocity. They are relatively easy to handle during sorting or loading, requiring less weight and space from the chute. Their kinetic energy is also lower, meaning their sliding speed is relatively slow, resulting in less friction from the chute walls and less impact on the chute. For example, a low-energy item could be a package containing several pieces of clothing, weighing approximately 1 kilogram. Because of their low gravitational potential energy and limited initial velocity, low-energy goods are prone to stopping within the chute, failing to reach the lower port or stopping there altogether, ultimately hindering the smooth completion of sorting operations.

[0007] Medium-energy goods typically refer to goods with energy levels between medium-energy and high-energy goods. They possess a certain weight and volume, and their kinetic energy during sliding in the chute is at a moderate level. There are specific operational procedures and precautions required during the sorting process. The initial velocity entering the chute from the higher port is neither low nor high. Due to the speed and kinetic energy they possess while sliding in the chute, they may experience minor collisions with other goods, but these usually do not cause serious damage. This places certain pressure and space requirements on the chute, but these are within normal tolerance limits. For example, a medium-energy cargo might be a parcel containing a small robotic vacuum cleaner, typically weighing several kilograms. Because medium-energy goods possess a certain speed and kinetic energy while sliding in the chute, they will alternately collide with the inner walls of the two sides of the chute along its width during the sliding process, but without causing serious impact to the inner walls of the chute.

[0008] High-energy goods are heavy and often large in volume, resulting in significant kinetic energy as they slide through the chute. This necessitates specific equipment and operational procedures during transportation, handling, and sorting, such as requiring specialized manpower or technical support during sorting and delivery. The initial velocity entering the chute from a higher port is substantial, potentially generating significant kinetic energy that could damage the chute and cause severe collisions with other goods during sliding, leading to damage to the high-energy goods themselves or other cargo. This also places high pressure resistance and space requirements on the chute. For example, a high-energy cargo might be a parcel containing small furniture, appliances, or fitness equipment, typically weighing tens of kilograms. Because of its speed and kinetic energy, the high-energy cargo will alternately impact the inner walls of the chute along its width during sliding, potentially causing severe impacts.

[0009] For the aforementioned medium-energy and high-energy goods, during sliding, they will contact the left and right side walls and bottom wall of the chute, creating a certain amount of friction with the inner wall of the chute. This friction depends on the specific material of the inner wall of the chute. If the friction is too high, given the weight and volume of the medium-energy and high-energy goods, there is a risk that they may stop inside the chute or fail to slide smoothly out of the chute exit. If the friction is too low, given the weight and volume of the medium-energy and high-energy goods, there is a risk that they may rush out of the lower port or out of the chute from the left and right side walls at a high speed, thus causing problems with sorting safety and cargo safety.

[0010] It should be noted that the comparison between low-energy, medium-energy, and high-energy goods mentioned above is merely an illustrative example to illustrate the differences between the three. Low-energy, medium-energy, and high-energy goods can be distinguished within certain threshold ranges. For example, goods can be classified as low-energy, medium-energy, and high-energy goods within a weight threshold range of 0-10kg. They can also be classified as low-energy, medium-energy, and high-energy goods within a weight threshold range of 0-100kg. Furthermore, they can be classified as low-energy, medium-energy, and high-energy goods within a weight threshold range of 100kg-1000kg. The mention of low-energy, medium-energy, and high-energy goods here is only to clarify the shortcomings of existing technology; in actual applications of existing technology, there is no inspiration for classifying goods by energy level.

[0011] In the prior art, low-energy goods, medium-energy goods and high-energy goods are generally transported through the same chute. The inner wall of the chute has a uniformly set friction force, which cannot be adapted to the transport of goods of all three energy levels at the same time. The uniformly set friction force causes at least one of the low-energy goods, medium-energy goods and high-energy goods to stagnate, be thrown out from both sides midway or rush out of the chute at a high speed during the sliding transport process, resulting in technical problems such as the inability to sort normally or the inability to guarantee the safety of goods and sorting. Summary of the Invention

[0012] The purpose of this application is to provide a chute and a cargo conveying mechanism. The chute is suitable for conveying cargo with a pressure on the inner wall of the chute at a third energy density of P > P1, and cargo with a first energy density of P < 1 / 3P1. It is less prone to technical problems such as cargo stagnation, being thrown out from both sides midway, or rushing out of the chute at a high speed, which would lead to the inability to sort normally or the inability to guarantee cargo safety and sorting safety.

[0013] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0014] A chute is provided. In the width direction of the chute, and in the direction from the center of the chute to the width edge of the chute, the inner wall of the chute has at least a first friction zone and a third friction zone. Both the first and third friction zones extend along the extension direction of the chute, and the friction coefficient of the third friction zone is greater than that of the first friction zone. The first friction zone is used to confine the trajectory of goods with a first energy density within the first friction zone, and the third friction zone is used to confine the trajectory of goods with a third energy density within the third friction zone and the first friction zone. The first and third friction zones are also used to make the outward speeds of the goods with the first energy density and the goods with the third energy density tend to be consistent. The third energy density is greater than the first energy density, and the energy density is the energy required to slide and transport a unit volume of the goods in the chute.

[0015] The inner wall of the chute is coated with a coating layer, which includes a base material and hard particles mixed in the base material; and the base material in the first friction zone and the third friction zone may be the same or different, and the particle size of the particles in the first friction zone is smaller than that of the particles in the third friction zone.

[0016] Furthermore, set 1dm 3 The pressure of the liquid water is P1 = 9.8 Pa. Let P be the pressure exerted by the cargo on the inner wall of the chute, and let P be positively correlated with the energy density. Then:

[0017] When P > P1, the cargo is cargo with the third energy density;

[0018] When P < 1 / 3P1, the cargo is cargo with the first energy density.

[0019] In some embodiments, the inner wall of the chute has two third friction zones, which are disposed on both sides of the first friction zone along the width direction. The two third friction zones are used to restrict the trajectory of the cargo with the third energy density between two outer edges of the two third friction zones that are opposite to each other along the width direction.

[0020] In some embodiments, the groove has concave sides and convex sides spaced apart along the width direction;

[0021] In the two third friction zones, the outer edge of one third friction zone is connected to the side edge of the concave side on the same side, and the outer edge of the other third friction zone is connected to the side edge of the convex side on the same side.

[0022] In some embodiments, the groove opening is open to the top, the first friction area is positioned directly opposite the groove opening along the height direction of the groove, and the third friction area is perpendicularly connected to the first friction area.

[0023] In some embodiments, on the side where the concave side is located, the third friction area protrudes toward the convex side, and the trend of the protrusion is synchronously matched with the trend of the concave side protruding toward the convex side; and, the protrusion is divided into a first protrusion and a second protrusion on both sides of the vertical line perpendicular to the tangent at the apex of the protrusion, the first protrusion is adjacent to the side where the inlet is located, and the second protrusion is connected to the outlet.

[0024] On the side where the convex side is located, and along the extending direction of the groove, the third friction area first protrudes towards the concave side and then all of them are recessed towards the convex side, thereby forming a continuous protrusion and a recess; and, the portion of the first protrusion near the inlet is offset from the protrusion along the extending direction, and the recess is directly opposite to the portion of the second protrusion and the portion of the first protrusion near the vertical line along the width direction.

[0025] The first protrusion is used to restrict the trajectory of the cargo with the third energy density for the first time, the portion of the recess near the protrusion is used to restrict the trajectory of the cargo with the third energy density for the second time, and the second protrusion is used to restrict the trajectory of the cargo with the third energy density for the third time, so that the cargo with the third energy density can be smoothly discharged from the outlet.

[0026] In some embodiments, the first protrusion and the second protrusion are continuously or discontinuously arranged along the extending direction, and the protrusion and the recess are continuously arranged along the extending direction.

[0027] In some embodiments, the chute includes multiple splicing structures and multiple support structures;

[0028] Multiple splicing structures are detachably spliced ​​along the extending direction to form the slide groove. The multiple splicing structures are detachably supported one-to-one on the top of multiple support structures, and the height of the multiple support structures decreases successively along the extending direction so that the slide groove is inclined relative to the horizontal plane.

[0029] In some embodiments, the splicing structure has a first connecting part at its bottom end and the supporting structure has a second connecting part at its top end. The first connecting part is movably connected to the second connecting part so that the angle of the splicing structure relative to the supporting structure is adjustable.

[0030] In some embodiments, the first connecting portion includes an arcuate groove, and the second connecting portion includes two protruding posts, which are arranged parallel to each other along the height direction of the support structure, and the protruding posts are perpendicularly connected to the support structure.

[0031] The splicing structure is rotatably connected to the support structure via one of the protruding posts, and the other protruding post extends into the arc-shaped groove to allow the splicing structure to rotate and adjust relative to the support structure within the angle defined by the arc-shaped groove.

[0032] The beneficial effects of the chute provided in this application are as follows:

[0033] Compared with the prior art, the chute provided in this application has at least a first friction zone and a third friction zone in the width direction of the chute, pointing from the center of the chute to the edge of the width. Both the first and third friction zones extend along the extension direction to guide the flow of goods along the extension direction. Because the particle size in the first friction zone is smaller than that in the third friction zone, the friction coefficient of the third friction zone is greater than that of the first friction zone. More specifically, the first friction zone is used to confine the trajectory of goods with a first energy density and a pressure on the inner wall of the chute of P < 1 / 3P1 within the first friction zone. The third friction zone is used to confine the trajectory of goods with a third energy density and a pressure on the inner wall of the chute of P > P1 within the third and first friction zones. The first and third friction zones also serve to make the discharge speed of goods with the first and third energy densities tend to be consistent at the discharge port.

[0034] Thus, goods with a first energy density and goods with a third energy density can be transported through the same chute. The first energy density goods and the third energy density goods can be low-energy goods and high-energy goods, respectively. The inner wall of the chute has a non-uniformly set friction force, which can simultaneously accommodate the transport of goods with two energy levels. The non-uniformly set friction force confines the goods within a constrained friction zone during the sliding transport process, preventing them from being thrown out from the sides or rushing out of the chute at high speed, which would lead to technical problems such as inability to sort normally or compromise of goods safety and sorting safety. Furthermore, the friction zone takes into account the required work capacity to ensure that the goods reach the outlet normally without any stagnation.

[0035] Another object of this application is to provide a cargo conveying mechanism, which includes a chute as described above and a conveyor belt, wherein the conveyor belt and the chute are arranged sequentially along the conveying path of the cargo, and the conveying end of the conveyor belt and the inlet of the chute are connected.

[0036] The cargo conveying mechanism provided in this application has the same beneficial effects as the chute provided in this application compared to the prior art. Due to the non-uniform frictional force, it can be adapted to the conveying of cargo with a pressure on the inner wall of the chute at the third energy density of P>P1, and cargo with a first energy density of P<1 / 3P1. The non-uniform frictional force restricts the cargo within the constrained friction zone during the sliding conveying process, preventing the cargo from being thrown out from both sides or rushing out of the chute at a high speed, which would lead to the inability to sort normally or the inability to guarantee cargo safety and sorting safety. Furthermore, the friction zone takes into account its required work capacity to ensure that the cargo reaches the outlet normally without any cargo stagnation. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0054] The chute 100 and the cargo conveying mechanism provided in the embodiments of this application will now be described. The first, second, and third embodiments will be described in detail based on the division of the friction zone, and the fourth embodiment will be described in detail from the structural perspective of the chute 100. In practical applications, the first, second, and third embodiments can be used in conjunction with the fourth embodiment.

[0055] Please see Figures 1 to 6The chute 100 provided in the first embodiment of this application is inclined relative to the horizontal plane. The chute 100 includes an inlet section 101, an arc-shaped section 102, and an outlet section 103 connected sequentially along the extension direction a of the chute 100. The arc-shaped section 102 is arc-shaped. The inlet section 101 and the outlet section 103 are set at an angle. The end of the inlet section 101 away from the arc-shaped section 102 is the inlet port 100a, and the goods to be transported are introduced into the chute 100 through the inlet port 100a. The end of the outlet section 103 away from the arc-shaped section 102 is the outlet port 100b, and the goods to be transported are discharged from the chute 100 through the outlet port 100b. The height position of the inlet port 100a is higher than the height position of the outlet port 100b.

[0056] Along the width direction b of the chute 100, and in the direction from the center of the chute 100 to the width edge of the chute 100, the inner wall of the chute 100 has at least a first friction zone 1001 and a second friction zone 1002. Both the first friction zone 1001 and the second friction zone 1002 extend along the extension direction a, and the friction coefficient of the second friction zone 1002 is greater than that of the first friction zone 1001. The first friction zone 1001 is used to restrict the trajectory of goods with a first energy density within the first friction zone 1001, and the second friction zone 1002 is used to restrict the trajectory of goods with a second energy density within the second friction zone 1002 and the first friction zone 1001. The first friction zone 1001 and the second friction zone 1002 are also used to make the discharge speed of goods with the first energy density and goods with the second energy density tend to be the same at the outlet 100b. The second energy density is greater than the first energy density, and the energy density is the energy required for a unit volume of goods to slide and be transported in the chute 100.

[0057] The first friction zone 1001 and the second friction zone 1002 are both extended along the extension direction a, so as to guide the goods along the extension direction a. The friction coefficient of the second friction zone 1002 is greater than that of the first friction zone 1001, so as to provide different friction forces for the goods.

[0058] Thus, at least goods with a first energy density and goods with a second energy density can be transported through the same chute 100. The inner wall of the chute 100 has a non-uniformly set friction force, which can simultaneously accommodate the transport of at least two types of energy goods. The non-uniformly set friction force restricts the goods within the constrained friction zone during the sliding transport process, preventing them from being thrown out from the sides or rushing out of the chute 100 at high speed, which would lead to technical problems such as inability to sort normally or inability to guarantee the safety of goods and sorting. Furthermore, the friction zone takes into account its required work capacity to ensure that the goods arrive at the outlet 100b normally without any stagnation.

[0059] Among them, the goods with the first energy density and the goods with the second energy density can be low-energy goods and medium-energy goods, or medium-energy goods and high-energy goods, or low-energy goods and high-energy goods, respectively.

[0060] Different goods have different volumes, densities, materials, or construction methods; different goods have different weights; and different goods have different initial velocities when entering the chute 100 from the inlet 100a. In other words, different goods have different gravitational potential energy in the chute 100, different frictional forces between different goods and the inner wall of the chute 100, and different kinetic energies in the chute 100. Ultimately, this leads to different sliding trajectories for different goods in the chute 100, and also increases the risk that some goods may not be able to slide out of the chute 100 from the outlet 100b.

[0061] Based on the different weights and volumes of various goods, the goods are distinguished by the different pressures they exert on the chute 100, classifying them into low-energy, medium-energy, and high-energy goods. Here, energy can refer to the energy possessed by the goods during movement, primarily including kinetic and potential energy, a physical quantity that measures the work capacity of the goods due to their motion and relative position. Alternatively, energy can refer to the energy density of the goods. The energy density of goods is positively correlated with their density; different goods densities exert different pressures on the chute 100, thus classifying the goods based on these pressure differences.

[0062] Low-energy goods are typically small in size and light in weight. Their initial velocity when entering the chute 100 from the inlet 100a is low, making them relatively easy to handle during the sorting or assembly process. This results in lower load requirements and space requirements for the chute 100. The kinetic energy they possess when sliding in the chute 100 is also low, meaning their sliding speed is relatively slow. Consequently, the frictional force from the inner wall of the chute has a relatively small impact on the chute 100, preventing significant impact on it.

[0063] Medium-energy goods typically refer to goods with energy levels between medium-energy and high-energy goods. They have a certain weight and volume, and their kinetic energy is at a moderate level when sliding in the chute 100. There are certain operational procedures and precautions required during the sorting process. The initial velocity of goods entering the chute 100 from the inlet 100a is neither low nor high. Due to the certain speed and kinetic energy they possess while sliding in the chute 100, they may experience minor collisions with other goods, but these usually do not cause serious damage. This places certain pressure and space requirements on the chute 100, but these are within normal tolerance limits.

[0064] High-energy goods are heavy and often large in volume, resulting in significant kinetic energy as they slide through the chute 100. This necessitates specific equipment and operational procedures during transportation, handling, and sorting. For instance, specialized human or technical support is required during sorting and delivery. The initial velocity of goods entering the chute 100 from the inlet 100a is high, potentially generating substantial kinetic energy that could damage the chute 100. Furthermore, the goods are prone to severe collisions with other goods during sliding, leading to damage to the high-energy goods themselves or other cargo. This also places high demands on the chute 100's pressure resistance and space requirements.

[0065] It should be noted that the comparison between low-energy goods, medium-energy goods, and high-energy goods mentioned above is merely an illustrative example to illustrate the differences between the three, and is not an absolute definition or setting. Furthermore, the definition method can be based on a comprehensive consideration of one or more of the following: weight, volume, material, pressure, and energy density. This application embodiment does not impose more specific constraints on this. Moreover, low-energy goods, medium-energy goods, and high-energy goods can be defined within certain threshold ranges, and this application embodiment does not impose more specific constraints on this. For example, goods can be classified as low-energy goods, medium-energy goods, and high-energy goods within a weight threshold range of 0-10kg. Goods can also be classified as low-energy goods, medium-energy goods, and high-energy goods within a weight threshold range of 0-100kg. Alternatively, goods can be classified as low-energy goods, medium-energy goods, and high-energy goods within a weight threshold range of 100kg-1000kg.

[0066] For example, in some embodiments, the energy density of the cargo is defined by the pressure P exerted by the cargo on the inner wall of the chute 100, and the energy density of the cargo is directly proportional to its density. The natural density of liquid water is set to ρ = 1000 g / dm³. 3 As a standard, its calculation formula is ρ=m / V, where m is the mass of the goods, V is the volume of the goods, and the frictional force per unit area of ​​the goods is positively correlated with the pressure, taken as 1 dm. 3 Using a pressure of P1 = 9.8 Pa as a standard, and setting the pressure of the cargo on the inner wall of the chute 100 as P, then: when P > P1, the cargo has a third energy density, or it can be a high-energy cargo; when 1 / 3P1 ≤ P < ≤ P1, the cargo has a second energy density, or it can be a medium-energy cargo; when P < 1 / 3P1, the cargo has a first energy density, or it can be a low-energy cargo.

[0067] In some embodiments, the inner wall of the chute 100 has two second friction zones 1002, which are disposed on both sides of the first friction zone 1001 along the width direction b. The two second friction zones 1002 are used to restrict the trajectory of the cargo with the second energy density between two outer edges of the two second friction zones 1002 that are opposite to each other along the width direction b.

[0068] In some embodiments, the inner wall of the chute 100 further has a third friction zone 1003; in the width direction b of the chute 100, and in the direction from the center of the chute 100 to the width edge of the chute 100, the first friction zone 1001, the second friction zone 1002, and the third friction zone 1003 have a greater coefficient of friction than the second friction zone 1002. The third friction zone 1003 is used to restrict the trajectory of the cargo with the third energy density within the third friction zone 1003, the second friction zone 1002, and the first friction zone 1001, and to make the discharge speed of the cargo with the third energy density at the outlet 100b tend to be consistent with the discharge speed of the cargo with the first energy density and the cargo with the second energy density at the outlet 100b; wherein, the third energy density is greater than the second energy density.

[0069] In some embodiments, the inner wall of the chute 100 has two second friction zones 1002 and two third friction zones 1003; the two second friction zones 1002 are disposed on both sides of the first friction zone 1001 along the width direction b, and the two second friction zones 1002 are used to restrict the trajectory of the goods with the second energy density between two outer edges of the two second friction zones 1002 that are opposite to each other along the width direction b; the two third friction zones 1003 are disposed on both sides of the second friction zones 1002 along the width direction b, and the two third friction zones 1003 are used to restrict the trajectory of the goods with the third energy density between two outer edges of the two third friction zones 1003 that are opposite to each other along the width direction b.

[0070] like Figure 3 The trajectory 1 shown restricts the trajectory of the cargo with the first energy density to two opposite outer edges of the first friction zone 1001 along the width direction b. (See example...) Figure 3 The trajectory 2 shown restricts the trajectory of the cargo with the second energy density to two outer edges of the two second friction zones 1002 that are opposite to each other along the width direction b. Figure 2 The trajectory 3 shown restricts the trajectory of the cargo with the third energy density to the two outer edges of the two third friction zones 1003 that are opposite to each other along the width direction b.

[0071] In some embodiments, the first friction region 1001, the second friction region 1002, and the third friction region 1003 each have a starting end and a ending end along the extending direction a. The starting end and the ending end of the first friction region 1001 are respectively flush with the edge of the inlet 100a and the edge of the outlet 100b; the starting end of the second friction region 1002 is spaced apart from the edge of the inlet 100a along the extending direction a; the starting end of the third friction region 1003 is located on the side of the starting end of the second friction region 1002 away from the inlet 100a; and the ending ends of both the second friction region 1002 and the third friction region 1003 are flush with the edge of the outlet 100b.

[0072] In other words, at the inlet 100a of the chute 100, the first friction zone 1001 occupies the entire width of the chute 100 along the width direction b. Goods of different energy densities enter the chute 100 from the inlet 100a and first enter the first friction zone 1001. After sliding a certain distance in the first friction zone 1001, they begin to contact the second friction zone 1002 and the third friction zone 1003 according to their different energy densities. The second friction zone 1002 and the third friction zone 1003 then autonomously select goods of different energy densities and limit their trajectory range.

[0073] In some embodiments, the groove 100 is open and facing directly upwards, the first friction area 1001 is positioned directly opposite the groove opening along the height direction c of the groove 100, the second friction area 1002 is connected to the first friction area 1001 at an obtuse angle, the third friction area 1003 is connected to the second friction area 1002 at an obtuse angle, and the third friction area 1003 and the first friction area 1001 tend to be vertically connected.

[0074] Along the width direction b of the slide groove 100, the cross-section of the slide groove 100 is approximately U-shaped, and the central area is the first friction zone 1001. The first friction zone 1001 occupies most of the bottom wall area of ​​the slide groove 100. The two side walls of the slide groove 100 are located on both sides of the bottom wall along the width direction b, and the side walls and the bottom wall are smoothly connected by an arc-shaped chamfer.

[0075] The second friction zone 1002 can occupy a small portion of the side area of ​​the bottom wall along the width direction b, as well as a small portion of the side wall near the bottom wall. In other words, the second friction zone 1002 covers the area of ​​the arc-shaped chamfer. The third friction zone 1003 can occupy most of the area of ​​the side wall near the groove opening.

[0076] It should be noted that the dimensions occupied by the first friction zone 1001, the second friction zone 1002, and the third friction zone 1003 along the width direction b can be increased or decreased according to different needs, and are not limited to the above-mentioned size occupation scheme.

[0077] In some embodiments, the slide groove 100 has a concave side 1004 and a convex side 1005 disposed opposite to each other along the width direction b; the extension dimensions of the two second friction regions 1002 along the width direction b tend to be the same, the extension dimension of the third friction region 1003 located on the convex side 1005 of the slide groove 100 along the width direction b is greater than the extension dimension of the third friction region 1003 located on the concave side 1004 of the slide groove 100 along the width direction b; and / or, the extension dimension of the first friction region 1001 along the width direction b is greater than the extension dimension of the second friction region 1002 along the width direction b and greater than the extension dimension of the third friction region 1003 along the width direction b.

[0078] For example, the dimension of the first friction region 1001 along the width direction b can be much larger than the extension dimension of the second friction region 1002 along the width direction b, and can even be twice or more than the extension dimension of the second friction region 1002 along the width direction b. Similarly, the dimension of the first friction region 1001 along the width direction b can be much larger than the extension dimension of the third friction region 1003 along the width direction b, and can even be twice or more than the extension dimension of the third friction region 1003 along the width direction b.

[0079] In some embodiments, the groove 100 has a concave side 1004 and a convex side 1005 disposed opposite to each other along the width direction b; on the side where the concave side 1004 is located, the second friction area 1002 and the third friction area 1003 protrude synchronously toward the convex side 1005, and the trend of the protrusion is synchronously matched with the trend of the concave side 1004 protruding toward the convex side 1005; and, the protrusion is divided into a first protrusion 1004a and a second protrusion 1004b disposed on both sides of the vertical line d perpendicular to the tangent at the apex of the protrusion, the first protrusion 1004a is adjacent to the side where the inlet 100a is located, and the second protrusion 1004b is connected to the outlet 100b.

[0080] On the side where the convex side 1005 is located, and along the extension direction a of the slide groove 100, the second friction area 1002 and the third friction area 1003 both first bulge towards the concave side 1004 and then both bulge towards the convex side 1005, thus forming a continuous convex portion 1005a and a concave portion 1005b; and the portion of the first convex portion 1004a near the inlet 100a is offset from the convex portion 1005a along the extension direction a, and the concave portion 1005b is directly opposite to the second convex portion 1004b and the portion of the first convex portion 1004a near the vertical line d along the width direction b.

[0081] The first protrusion 1004a is used to restrict the trajectory of the goods with the second energy density and the goods with the third energy density for the first time. The portion of the recess 1005b near the protrusion 1005a is used to restrict the trajectory of the goods with the second energy density and the goods with the third energy density for the second time. The second protrusion 1004b is used to restrict the trajectory of the goods with the second energy density and the goods with the third energy density for the third time, thereby allowing the goods with the second energy density and the goods with the third energy density to be smoothly discharged from the outlet 100b.

[0082] The first friction zone 1001, the second friction zone 1002, and the third friction zone 1003 can extend continuously or intermittently along the extension direction a. For example, in the second friction zone 1002, the first protrusion 1004a and the second protrusion 1004b can be intermittently arranged, and the goods can be restricted in their trajectory by passing through the first protrusion 1004a and the second protrusion 1004b with a high probability. In this case, the area between the first protrusion 1004a and the second protrusion 1004b may not be a friction zone, or it may be the first friction zone 1001. For example, in the third friction zone 1003, the protrusion 1005a and the recess 1005b can be intermittently arranged, and the goods can be restricted in their trajectory by passing through the protrusion 1005a and the recess 1005b with a high probability. In this case, the area between the protrusion 1005a and the recess 1005b may not be a friction zone, or it may be the first friction zone 1001 or the second friction zone 1002.

[0083] In some embodiments, the inner wall of the chute 100 is coated with a coating layer, which includes a base material and hard particles mixed in the base material; and the base materials in the first friction zone 1001, the second friction zone 1002 and the third friction zone 1003 are the same or different, the particle size of the particles in the first friction zone 1001 is smaller than the particle size of the particles in the second friction zone 1002, and the particle size of the particles in the second friction zone 1002 is smaller than the particle size of the particles in the third friction zone 1003.

[0084] In some embodiments, the coating layer can be polytetrafluoroethylene (PTFE), which has an extremely low coefficient of friction, typically around 0.04. It exhibits excellent chemical stability and corrosion resistance, and when coated on the inner wall of the chute 100, it can significantly reduce the friction between the goods and the chute wall, allowing the goods to slide quickly and smoothly. This is particularly suitable for lightweight, friction-sensitive goods, effectively controlling their sliding speed and reducing jamming and clogging. For example, the PTFE can be coated at least in the first friction zone 1001.

[0085] In some embodiments, the coating layer can be a polyurethane coating, which has good wear resistance, flexibility, and impact resistance. The coefficient of friction can be varied within a certain range by adjusting the formula, generally between 0.3 and 0.6. Simultaneously, it has good oil resistance, water resistance, and aging resistance. The formula of the polyurethane coating can be adjusted according to the characteristics of the goods and the operating environment of the chute 100 to obtain a suitable coefficient of friction. This ensures that the goods have a certain sliding speed while providing appropriate friction to prevent excessive speed or slippage and loss of control, making it suitable for goods of various weights and materials.

[0086] In some embodiments, the coating layer can be a silicone rubber coating, which has good elasticity, high temperature resistance, and electrical insulation, a relatively low coefficient of friction (generally between 0.2 and 0.4), and a smooth surface, effectively reducing friction between the goods and the chute walls. Furthermore, it also exhibits excellent weather resistance and biocompatibility. For goods that are easily scratched or require surface protection, the silicone rubber coating can provide cushioning and protection, while its low coefficient of friction helps the goods slide smoothly within the chute 100. It can be used to transport fragile or easily scratched goods such as electronic products and glassware.

[0087] In some embodiments, the coating layer can be a ceramic coating, which has high hardness, high wear resistance, high temperature resistance, and chemical stability, with a coefficient of friction between 0.3 and 0.5. The ceramic coating also has good self-lubricating properties, which can reduce frictional loss to a certain extent. It is suitable for high-speed, high-frequency use of the slide rail 100, can withstand greater frictional and impact forces, reduce wear, and extend the service life of the slide rail 100. For heavy goods with high sliding speeds, the ceramic coating can provide a stable coefficient of friction, ensuring that the sliding trajectory of the goods is controllable.

[0088] In some embodiments, the aforementioned particles can be glass microspheres, which possess excellent wear resistance, chemical stability, and sphericity, with a smooth surface that effectively reduces the coefficient of friction. The particle size of the glass microspheres is generally between tens and hundreds of micrometers, and can be selected as needed. Uniformly distributing the glass microspheres on the inner wall of the chute 100 enables rolling friction between the goods and the chute wall, significantly reducing friction and increasing the sliding speed of the goods. Simultaneously, the uniform distribution of the glass microspheres helps maintain a stable sliding trajectory for the goods.

[0089] In some embodiments, the aforementioned particulate matter can be graphite particles, which have good lubricity and conductivity, and a low coefficient of friction between 0.1 and 0.3. Graphite particles can form a lubricating film between the cargo and the trough wall, reducing direct contact and friction. This effectively reduces the frictional force between the cargo and the trough wall. Especially in environments requiring anti-static properties, the conductivity of graphite particles can also eliminate static electricity, preventing damage to the cargo or equipment and ensuring the safe and smooth sliding of the cargo within the trough 100.

[0090] In some embodiments, the aforementioned particulate matter can be molybdenum disulfide (MoS2) particles, which, as a typical layered solid lubricant, have an extremely low coefficient of friction, generally between 0.05 and 0.1, and maintain good lubrication performance even under high temperature, high pressure, and high load conditions. Adding molybdenum disulfide particles to the inner wall of the chute 100 can form a highly efficient lubrication layer between the cargo and the chute wall. Even when the cargo is heavy and the sliding speed is fast, it can significantly reduce friction, reduce energy loss, effectively control the sliding speed and trajectory of the cargo, and improve the operating efficiency and stability of the chute 100.

[0091] The specific coating material and particles of the base layer can be appropriately selected according to actual needs. The base layers in the first friction zone 1001, the second friction zone 1002 and the third friction zone 1003 can be the same or different, and the particles in the first friction zone 1001, the second friction zone 1002 and the third friction zone 1003 can be the same or different.

[0092] The slide groove 100 will be described in detail below, taking into account the segmented areas of each friction zone and the physical principle of the slide groove 100.

[0093] As an example, such as Figure 3As shown, along the extension direction a of the groove 100, the first friction zone 1001 is divided into standard transport zone S1-1, standard transport zone S1-2, standard transport zone S1-3, and standard transport zone S1-4. Along the extension direction a of the groove 100, the second friction zone 1002, located on the same side as the concave side 1004, is divided into second density buffer zone S2-1, second density buffer zone S2-2, and second density buffer zone S2-3; the second friction zone 1002, located on the same side as the convex side 1005, is divided into second density buffer zone S2-1', second density buffer zone S2-2', and second density buffer zone S2-3'. Along the extension direction a of the groove 100, the third friction zone 1003 located on the same side as the concave side 1004 is divided into a third density buffer zone S3-1, a third density buffer zone S3-2, a third density buffer zone S3-3, and a third density buffer zone S3-4. The third friction zone 1003 located on the same side as the convex side 1005 is divided into a third density buffer zone S3-1', a third density buffer zone S3-2', and a third density buffer zone S3-3'.

[0094] As an example, different goods are subjected to two directional velocity components at their initial positions, namely velocity v1 and velocity v2. Among them, v1 is roughly horizontal, with a magnitude of about 1 m / s, which can be understood as the original forward direction of the goods. v2 is at approximately a 90-degree angle to v1, with a magnitude of about 1 m / s, which can be understood as the sorting direction of the goods.

[0095] As an example, all goods of different energy densities first pass through the standard transport zone S1-1. Goods with higher energy densities (e.g., goods with the third energy density) automatically pass through the second density buffer zone S2-1 and / or the third density buffer zone S3-1 (approximately the location of the first protrusion 1004a) sequentially, rushing towards the highest point. Under the reaction force, they are guided sequentially into the second density buffer zone S2-1' and / or the third density buffer zone S3-1' (approximately the portion of the recess 1005b near the protrusion 1005a). Thus, different friction zones have different coefficients of friction to adjust the trajectory of the goods. Again, under the reaction force, the goods are guided to the second density buffer zone S2-3 and / or the third density buffer zone S3-3, and the third density buffer zone S3-4 until the speed is reduced to v3, and they are sorted out of the chute 100 from the standard transport zone S1-4.

[0096] As an example, goods with intermediate energy density (e.g., goods with second energy density) first pass through the standard transport zone S1-1, then automatically pass through the second density buffer zone S2-1 (approximately the location of the first protrusion 1004a) to reach the highest point. Under the reaction force, they are guided to enter the second density buffer zone S2-1' (approximately the portion of the recess 1005b near the protrusion 1005a). Thus, different friction zones have different coefficients of friction to adjust the trajectory of the goods. Again, under the reaction force, the goods are guided to the second density buffer zone S2-3 until they are decelerated to v3 and sorted out of the chute 100 from the standard transport zone S1-4.

[0097] As an example, goods with lower energy density (e.g., goods with a first energy density) move in a parabolic motion in standard transport zones S1-1, S1-2, S1-3, and S1-4, and are sorted out of chute 100 from standard transport zone S1-4 at a final velocity of v3.

[0098] In this way, goods with different energy densities have different S-shaped movement paths and consume different amounts of energy, ultimately achieving sorting out of the chute 100 at a basically consistent speed in the standard transport areas S1-4, and safely and effectively entering the sorting position.

[0099] In this equation, the gravitational potential energy of the cargo is Ep = mgh, the kinetic energy is K = (M*V²) / 2, and the work done by friction is W = FS = mg*μs, where μs is the coefficient of friction. The cargo is acted upon by two forces during its motion: gravity and friction. Specifically, when the cargo moves downwards, gravitational potential energy is converted into kinetic energy; when the cargo moves upwards, gravitational potential energy partially cancels out the kinetic energy.

[0100] The initial energy of the cargo is k1 = (M*V1²) / 2 + (M*V2²) / 2, the energy during the cargo's slide is k2 = k1 + W + mgh, and the final energy of the cargo is k3 = (M*V3²) / 2. Therefore, w = k1 - k3 + mgh can be calculated. Thus, by appropriately designing the shape of the chute 100 and the friction coefficients of different areas based on w, cargoes with different energy densities can run on different motion paths, consuming different proportions of kinetic energy, achieving a similar motion speed at the exit position.

[0101] Based on the first embodiment described above, another objective of this application is to provide a cargo conveying mechanism, which includes the chute 100 as described above and a conveyor belt. The conveyor belt and the chute 100 are arranged in sequence along the cargo conveying path, and the conveying end of the conveyor belt and the inlet 100a of the chute 100 are connected.

[0102] The purpose of the second embodiment of this application is to provide a chute 100 suitable for goods with a second energy density where the pressure on the inner wall of the chute 100 is 1 / 3P1≤P<≤P1, and goods with a first energy density where P<1 / 3P1. This chute 100 is less prone to technical problems such as goods stagnating, being thrown out from both sides midway, or rushing out of the chute 100 at a high speed, which would lead to the inability to sort normally or the inability to guarantee the safety of goods and sorting.

[0103] Please see Figures 1 to 6 The chute 100 is located in the width direction b of the chute 100, and extends from the center of the chute 100 to the width edge of the chute 100. The inner wall of the chute 100 has at least a first friction zone 1001 and a second friction zone 1002. Both the first friction zone 1001 and the second friction zone 1002 extend along the extension direction a of the chute 100. The friction coefficient of the second friction zone 1002 is greater than that of the first friction zone 1001. The first friction zone 1001 is used to restrict the trajectory of goods with a first energy density within the first friction zone 1001. The second friction zone 1002 is used to restrict the trajectory of goods with a second energy density within the second friction zone 1002 and the first friction zone 1001. The first friction zone 1001 and the second friction zone 1002 are also used to make the output speed of goods with the first energy density and goods with the second energy density tend to be consistent. The second energy density is greater than the first energy density. Energy density is the energy required for a unit volume of goods to slide and be transported in the chute 100.

[0104] The inner wall of the chute 100 is coated with a coating layer, which includes a base material and hardened particles mixed in the base material. The base materials in the first friction zone 1001 and the second friction zone 1002 may be the same or different, and the particle size of the particles in the first friction zone 1001 is smaller than that of the particles in the second friction zone 1002. Furthermore, a 1dm... 3 The pressure of the liquid water is P1 = 9.8 Pa. Let P be the pressure exerted by the cargo on the inner wall of the chute 100, and let P be positively correlated with the energy density. Then: When 1 / 3P1 ≤ P < ≤ P1, the cargo has the second energy density; when P < 1 / 3P1, the cargo has the first energy density.

[0105] The second embodiment of this application can selectively transport goods with a first energy density and goods with a second energy density through the same chute 100. The first energy density goods and the second energy density goods can be low-energy goods and medium-energy goods, respectively, with a set pressure range. The inner wall of the chute 100 has a non-uniformly set friction force, which can simultaneously accommodate the transport of goods with two energy densities. The non-uniformly set friction force restricts the goods within the constrained friction zone during the sliding transport process, preventing them from being thrown out from both sides midway or rushing out of the chute 100 at high speed, which would lead to technical problems such as failure to sort normally or compromise of goods safety and sorting safety. Furthermore, the friction zone takes into account its required work capacity to ensure that the goods reach the outlet 100b normally without any stagnation.

[0106] In some embodiments, the inner wall of the chute 100 has two second friction zones 1002, which are disposed on both sides of the first friction zone 1001 along the width direction b. The two second friction zones 1002 are used to restrict the trajectory of the cargo with the second energy density between two outer edges of the two second friction zones 1002 that are opposite to each other along the width direction b.

[0107] In some embodiments, the groove 100 has a concave side 1004 and a convex side 1005 spaced apart along the width direction b; in the two second friction areas 1002, the outer edge of one second friction area 1002 is connected to or spaced apart from the side edge of the concave side 1004 on the same side, and the outer edge of the other second friction area 1002 is connected to or spaced apart from the side edge of the convex side 1005 on the same side.

[0108] In other words, the outer edge of the second friction area 1002 can be spaced apart from the side edge of the groove 100, or can extend directly to the side edge. For example, the second friction area 1002 can occupy the position occupied by the second friction area 1002 in the first embodiment, or the second friction area 1002 can occupy the position occupied by the second friction area 1002 in the first embodiment and the position occupied by the third friction area 1003.

[0109] In some embodiments, the groove 100 is open and facing directly upwards, the first friction area 1001 is positioned directly opposite the groove opening along the height direction c of the groove 100, the second friction area 1002 is connected to the first friction area 1001 at an obtuse angle, and the outer edge of the second friction area 1002 is spaced apart from the side edge on the same side.

[0110] In some embodiments, on the side where the concave side 1004 is located, the second friction area 1002 protrudes towards the convex side 1005, and the trend of this protrusion synchronously matches the trend of the concave side 1004 protruding towards the convex side 1005; and, the protrusion is divided into a first protrusion 1004a and a second protrusion 1004b on both sides of the vertical line d, with the first protrusion 1004a adjacent to the side where the inlet 100a is located, and the second protrusion 1004b connected to the outlet 100b; on the side where the convex side 1005 is located, and along the extension direction a of the groove 100, the second friction area 1002 first protrudes towards the concave side 1004 and then both concave towards the convex side 1005, thereby A series of protrusions 1005a and recesses 1005b are formed; and the portion of the first protrusion 1004a near the inlet 100a is offset from the protrusion 1005a along the extending direction a, and the recesses 1005b are directly opposite the second protrusion 1004b and the portion of the first protrusion 1004a near the vertical line d along the width direction b; the first protrusion 1004a is used to restrict the trajectory of the goods with the second energy density for the first time, the portion of the recesses 1005b near the protrusion 1005a is used to restrict the trajectory of the goods with the second energy density for the second time, and the second protrusion 1004b is used to restrict the trajectory of the goods with the second energy density for the third time, so that the goods with the second energy density can be smoothly discharged from the outlet 100b.

[0111] The first protrusion 1004a and the second protrusion 1004b are either continuously or discontinuously arranged along the extension direction a, and the protrusion 1005a and the recess 1005b are continuously arranged along the extension direction a.

[0112] Based on the second embodiment above, another objective of this application is to provide a cargo conveying mechanism, which includes the chute 100 as described above and a conveyor belt. The conveyor belt and the chute 100 are arranged in sequence along the cargo conveying path, and the conveying end of the conveyor belt and the inlet 100a of the chute 100 are connected.

[0113] The purpose of the third embodiment of this application is to provide a chute 100 suitable for goods with a third energy density where the pressure on the inner wall of the chute 100 is P > P1, and goods with a first energy density where P < 1 / 3P1. This chute 100 is less prone to technical problems such as goods stagnating, being thrown out from both sides midway, or rushing out of the chute 100 at a high speed, which would lead to the inability to sort normally or the inability to guarantee the safety of goods and sorting.

[0114] Please see Figures 1 to 6It is located in the width direction b of the groove 100, and extends from the center of the groove 100 to the width edge of the groove 100. The inner wall of the groove 100 has at least a first friction region 1001 and a third friction region 1003. Both the first friction region 1001 and the third friction region 1003 extend along the extension direction a of the groove 100, and the friction coefficient of the third friction region 1003 is greater than that of the first friction region 1001. The first friction region 1001 is used to transfer a material with a first energy density. The trajectory of the goods is restricted within the first friction zone 1001. The third friction zone 1003 is used to restrict the trajectory of the goods with the third energy density within the third friction zone 1003 and the first friction zone 1001. The first friction zone 1001 and the third friction zone 1003 are also used to make the outward speed of the goods with the first energy density and the goods with the third energy density tend to be consistent. The third energy density is greater than the first energy density. The energy density is the energy required for a unit volume of goods to slide and be transported in the chute 100.

[0115] The inner wall of the chute 100 is coated with a coating layer, which includes a base material and hardened particles mixed in the base material. The base materials in the first friction zone 1001 and the third friction zone 1003 may be the same or different, and the particle size of the particles in the first friction zone 1001 is smaller than that of the particles in the third friction zone 1003. Furthermore, a 1dm... 3 The pressure of the liquid water is P1 = 9.8 Pa. Let P be the pressure exerted by the cargo on the inner wall of the chute 100. P is positively correlated with energy density. Then: when P > P1, the cargo has the third energy density; when P < 1 / 3 P1, the cargo has the first energy density.

[0116] The third embodiment of this application can selectively transport goods with a first energy density and goods with a third energy density through the same chute 100. The first energy density goods and the third energy density goods can be low-energy goods and high-energy goods, respectively, with a set pressure range. The inner wall of the chute 100 has a non-uniformly set friction force, which can simultaneously accommodate the transport of goods with two energy densities. The non-uniformly set friction force restricts the goods within the constrained friction zone during the sliding transport process, preventing them from being thrown out from both sides midway or rushing out of the chute 100 at high speed, which would lead to technical problems such as failure to sort normally or inability to guarantee the safety of goods and sorting. Furthermore, the friction zone takes into account its required work capacity to ensure that the goods arrive at the outlet 100b normally without any stagnation.

[0117] In some embodiments, the inner wall of the chute 100 has two third friction zones 1003, which are disposed on both sides of the first friction zone 1001 along the width direction b. The two third friction zones 1003 are used to restrict the trajectory of the cargo with the third energy density between two outer edges of the two third friction zones 1003 that are opposite to each other along the width direction b.

[0118] In some embodiments, the groove 100 has a concave side 1004 and a convex side 1005 spaced apart along the width direction b. In the two third friction areas 1003, the outer edge of one third friction area 1003 is connected to the side edge of the concave side 1004 on the same side, and the outer edge of the other third friction area 1003 is connected to the side edge of the convex side 1005 on the same side.

[0119] In some embodiments, the groove 100 is open and facing directly upwards, the first friction area 1001 is positioned directly opposite the groove opening along the height direction c of the groove 100, and the third friction area 1003 is vertically connected to the first friction area 1001.

[0120] In some embodiments, on the side where the concave side 1004 is located, the third friction area 1003 protrudes toward the convex side 1005, and the trend of this protrusion is synchronously matched with the trend of the concave side 1004 protruding toward the convex side 1005; and, the protrusion is divided into a first protrusion 1004a and a second protrusion 1004b on both sides of the vertical line d, with the first protrusion 1004a adjacent to the side where the inlet 100a is located, and the second protrusion 1004b connected to the outlet 100b. On the side where the convex side 1005 is located, and along the extending direction a of the slide groove 100, the third friction area 1003 first protrudes towards the concave side 1004 and then retracts towards the convex side 1005, thus forming continuous protrusions 1005a and recesses 1005b; and, the portion of the first protrusion 1004a near the inlet 100a is offset from the protrusion 1005a along the extending direction a, while the recesses 1005b are directly opposite the second protrusion 1004b and the portion of the first protrusion 1004a near the vertical line d along the width direction b. The first protrusion 1004a is used to first restrict the trajectory of the goods with the third energy density, the portion of the recesses 1005b near the protrusion 1005a is used to second restrict the trajectory of the goods with the third energy density, and the second protrusion 1004b is used to third restrict the trajectory of the goods with the third energy density, thereby allowing the goods with the third energy density to be smoothly discharged from the outlet 100b.

[0121] The first protrusion 1004a and the second protrusion 1004b are either continuously or discontinuously arranged along the extension direction a, and the protrusion 1005a and the recess 1005b are continuously arranged along the extension direction a.

[0122] Based on the third embodiment described above, another objective of this application is to provide a cargo conveying mechanism, which includes the chute 100 as described above and a conveyor belt. The conveyor belt and the chute 100 are arranged in sequence along the cargo conveying path, and the conveying end of the conveyor belt and the inlet 100a of the chute 100 are connected.

[0123] The chute 100 provided in the fourth embodiment of this application has a non-uniform structure on the inner wall of the chute. Specific protruding structures and recessed structures are added on both sides of the width direction b, which can simultaneously adapt to the conveying of at least two types of energy goods. The non-uniform structure restricts the goods between the specific protruding structures and recessed structures during the sliding conveying process, ensuring normal sorting or the safety of the goods.

[0124] Please see Figures 1 to 6 It has a concave side 1004 and a convex side 1005 disposed opposite to each other along the width direction b of the groove 100, and an inlet 100a and an outlet 100b communicating along the extension direction a of the groove 100. On the side where the concave side 1004 is located, the inner wall of the groove 100 has at least two protrusions, namely a first protrusion 1004a and a second protrusion 1004b, which are arranged sequentially along the extension direction a.

[0125] On the side where the convex side 1005 is located, the inner wall of the groove 100 has at least a protrusion 1005a and a recess 1005b. The protrusion 1005a and the recess 1005b are arranged sequentially along the extending direction a. The protrusion 1005a protrudes towards the concave side 1004, and the recess 1005b is recessed towards the convex side 1005. Furthermore, the portion of the first protrusion 1004a near the inlet 100a is offset from the protrusion 1005a along the extending direction a. The recess 1005b and the second protrusion 1004b and the portion of the first protrusion 1004a away from the inlet 100a are arranged opposite each other along the width direction b. Both the second protrusion 1004b and the recess 1005b are connected to the outlet 100b.

[0126] Thus, by adding specific protruding and recessed structures on both sides of the width direction b of the same chute 100, goods with different energy densities can be flexibly guided. Compared with the uniform structure of the inner wall of the existing chute 100, the addition of specific protruding and recessed structures on both sides of the width direction b can simultaneously accommodate the conveying of at least two types of energy goods. The non-uniform structure restricts the goods between the specific protruding and recessed structures during the sliding conveying process, preventing them from being thrown out from both sides or rushing out of the chute 100 at high speed, which would lead to problems such as the inability to sort normally or the inability to guarantee the safety of goods and sorting. Moreover, the structural design takes into account the required workload to ensure that the goods arrive at the outlet 100b normally without any stagnation.

[0127] The first protrusion 1004a is used to restrict the trajectory of the goods for the first time, the portion of the recess 1005b near the protrusion 1005a is used to restrict the trajectory of the goods for the second time, and the second protrusion 1004b is used to restrict the trajectory of the goods for the third time, so that the goods can be smoothly discharged from the outlet 100b.

[0128] In some embodiments, the first protrusion 1004a and the second protrusion 1004b are continuously or discontinuously arranged along the extending direction a, and the protrusion 1005a and the recess 1005b are continuously arranged along the extending direction a.

[0129] In some embodiments, the first protrusion 1004a and the second protrusion 1004b are continuously disposed along the extending direction a to form a protrusion on the concave side 1004, and the trend of the protrusion is synchronously matched with the trend of the concave side 1004 protruding towards the convex side 1005; and the protrusion is divided into the first protrusion 1004a and the second protrusion 1004b disposed on both sides of the vertical line d perpendicular to the tangent at the apex of the protrusion. As an example, the maximum size occupied by the first protrusion 1004a and the second protrusion 1004b along the width direction b of the groove 100 is smaller than the maximum size occupied by the protrusion 1005a and the recess 1005b along the width direction b.

[0130] In some embodiments, the chute 100 includes a plurality of splicing structures 11 and a plurality of supporting structures 12. The plurality of splicing structures 11 are detachably spliced ​​along the extension direction a to form the chute 100. The plurality of splicing structures 11 are detachably supported one-to-one on the top of the plurality of supporting structures 12, and the height of the plurality of supporting structures 12 is gradually reduced along the extension direction a so that the chute 100 is inclined relative to the horizontal plane.

[0131] In some embodiments, the chute 100 includes an inlet section 101, an arc-shaped section 102, and an outlet section 103 connected sequentially along the extension direction a. The arc-shaped section 102 is arc-shaped, and the inlet section 101 and the outlet section 103 are set at an angle. The end of the inlet section 101 away from the arc-shaped section 102 is an inlet port 100a, through which goods are introduced into the chute 100. The end of the outlet section 103 away from the arc-shaped section 102 is an outlet port 100b, through which goods are discharged from the chute 100. The height of the inlet port 100a is higher than that of the outlet port 100b. The inlet section 101 includes at least two splicing structures 11 sequentially spliced ​​along the extension direction a, and the outlet section 103 includes at least two splicing structures 11 sequentially spliced ​​along the extension direction a.

[0132] In some embodiments, the inlet groove segment 101 includes two splicing structures 11 sequentially spliced ​​along the extension direction a, pointing from the inlet port 100a to the arc-shaped groove segment 102, and the two sides of the width direction b of the inlet groove segment 101 are gradually narrowed; the outlet groove segment 103 includes two splicing structures 11 sequentially spliced ​​along the extension direction a, pointing from the arc-shaped groove segment 102 to the outlet port 100b, and the two sides of the width direction b of the outlet groove segment 103 are parallel.

[0133] In some embodiments, a first connecting part is provided at the bottom of the splicing structure 11, and a second connecting part is provided at the top of the support structure 12. The first connecting part is movably connected to the second connecting part so that the angle of the splicing structure 11 relative to the support structure 12 is adjustable.

[0134] As an example, the first connecting part includes an arc-shaped groove 111, and the second connecting part includes two protrusions 121. The two protrusions 121 are arranged parallel to each other along the height direction c of the support structure 12, and the protrusions 121 are perpendicularly connected to the support structure 12. The splicing structure 11 is rotatably connected to the support structure 12 through one protrusion 121, and the other protrusion 121 extends into the arc-shaped groove 111 to allow the splicing structure 11 to rotate and adjust relative to the support structure 12 within the angle defined by the arc-shaped groove 111.

[0135] Based on the fourth embodiment described above, another objective of this application is to provide a cargo conveying mechanism, which includes the chute 100 as described above and a conveyor belt. The conveyor belt and the chute 100 are arranged in sequence along the cargo conveying path, and the conveying end of the conveyor belt and the inlet 100a of the chute 100 are connected.

[0136] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
