Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and in particular to a continuous conveying device for construction waste. Background Technology

[0002] Urban construction and demolition generate a large amount of construction waste, requiring centralized processing. Traditional transportation methods mainly rely on intermittently operating dump trucks, which are inefficient and cannot meet the needs of large-scale processing. Belt conveyors, as a common continuous conveying equipment, are widely used in mining, metallurgy, and other industries due to their simple structure, large conveying capacity, and low operating costs, and are gradually being adopted in the field of construction waste treatment. In existing technologies, belt conveyors used for transporting construction waste typically use rubber conveyor belts with multi-layered fabric cores or steel rope cores. Power is provided by drive rollers, and the belt is supported and guided by idler rollers, enabling continuous material transport in horizontal or inclined directions. Some designs also include anti-deviation and emergency braking devices to ensure operational safety.

[0003] Existing belt conveyor equipment is prone to material spillage when feeding a large amount of material, which not only wastes material but also affects the operation of the equipment. Therefore, it is necessary to manually adjust the trough angle of the conveyor belt. However, the degree of manual adjustment is not easy to control, which affects the running resistance of the conveyor belt.

[0004] The information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this invention and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] Therefore, it is necessary to provide a continuous conveying device for construction waste to address the problems existing in current belt conveyor equipment.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A continuous conveying device for construction waste includes a support frame, on which a conveyor belt is mounted, and a drive roller and idler roller assembly for running the conveyor belt. The idler roller assembly includes a bottom roller and two side rollers. The axis of the bottom roller is horizontal and perpendicular to the conveying direction of the conveyor belt. The two side rollers are symmetrically arranged on both sides of a first plane passing through the geometric center of the bottom roller and perpendicular to its axis. The end of each side roller furthest from the bottom roller is the outer end, and the end closest to the bottom roller is the inner end. The outer end of each side roller is higher than its inner end, causing the conveyor belt, supported by the bottom roller and the side rollers, to form a trough angle in the conveying direction of the conveyor belt. Upward, the distance between the outer end of the side roller and the axis of the bottom roller is greater than the distance between the inner end of the side roller and the axis of the bottom roller; the diameter of the side roller gradually decreases from its outer end to its inner end, and the generatrix of the circumferential surface of the side roller is an outwardly convex arc; the portion of the conveyor belt that contacts the circumferential surface of the side roller has a first slope; the conveyor belt is elastic, and it contacts the side roller in an arc; the slope of the tangent corresponding to the midpoint of the contact arc is the first slope; the side roller can move along its axial direction and has a tendency to move closer to the bottom roller; when the amount of material fed to the conveyor belt is greater than a first preset value, the material pushes the side roller away from the bottom roller, increasing the first slope and the groove angle.

[0008] Furthermore, the support is provided with a uniform distribution component corresponding to the idler roller assembly. The uniform distribution component includes a uniform distribution plate. The side roller has an initial position. When it is in the initial position, the side roller is closest to the bottom roller. When the difference in the distance that the two side rollers move relative to the initial position is greater than a second preset value, the uniform distribution plate rotates and its rotation axis is perpendicular to the axis of the bottom roller and the conveying direction of the conveyor belt. When the uniform distribution plate rotates, it agitates and makes the material on the conveyor belt evenly distributed.

[0009] Furthermore, the idler roller assembly also includes a first piston cylinder corresponding to the side roller, and a first chamber is formed inside the first piston cylinder. The even distribution assembly also includes two coaxially arranged second piston cylinders, and a second chamber is formed inside the second piston cylinder. The first chamber and the second chamber are connected and filled with a flowing medium. A movable member capable of moving along the axial direction of the second piston cylinder is provided in the second chamber. An intermediate member connected to the even distribution plate is provided between the two movable members. When the side roller moves away from the bottom roller, the first chamber is compressed and the movable member is pushed by the flowing medium. The movable member applies a force to the intermediate member. When the difference in the distance that the two side rollers have moved relative to the initial position is greater than a second preset value, the difference in the force applied by the two movable members to the intermediate member is greater than a third preset value, and the even distribution plate rotates.

[0010] Furthermore, the intermediate component is a cam, the rotation axis of the intermediate component is offset from the axis of the second piston cylinder, the moving component has a fixed end and a telescopic end, the telescopic end and the fixed end can extend and retract relative to each other along the axial direction of the second piston cylinder, the fixed end can move along the axial direction of the second piston cylinder, and the telescopic end contacts the outer contour of the intermediate component.

[0011] Furthermore, the first piston cylinder is provided with a damping element, which is used to slow down the movement of the side roller along its axial direction.

[0012] Furthermore, when the difference in distance between the two side rollers relative to the initial position is greater than a second preset value, the uniform distribution plate rotates and moves toward the conveyor belt, and the uniform distribution plate has a tendency to move away from the conveyor belt.

[0013] Furthermore, the support is provided with a pressure roller, the axis of which is parallel to the axis of the bottom roller. When the pressure roller rotates, it can apply pressure to the material on the conveyor belt. The pressure roller is spaced apart from the conveyor belt and has a tendency to move closer to the conveyor belt.

[0014] Furthermore, the support is equipped with a dust cover, which is located above the conveyor belt.

[0015] Furthermore, the support frame is equipped with a cleaning component, and the conveyor belt includes a conveying section and a return section, the cleaning component being used to clean the return section.

[0016] Furthermore, the bracket is provided with a first base and a second base, the first base and the second base are rotatable relative to each other and the rotation axis is parallel to the axis of the bottom roller, the roller assembly is disposed on the second base, and a limiting member is provided between the first base and the second base, the limiting member being used to limit the rotation angle of the first base and the second base.

[0017] The present invention has at least the following beneficial effects:

[0018] (1) When the amount of material on the conveyor belt is greater than the first preset value, the material pushes the side roller away from the bottom roller, and the conveyor belt deforms at the same time. The first slope and trough angle increase, reducing material waste caused by spillage and avoiding affecting equipment operation. The size of the trough angle is automatically adjusted by the amount of material on the conveyor belt. There is no need for manual adjustment and the degree of adjustment of the trough angle is easy to control, thereby optimizing the running resistance of the conveyor belt.

[0019] (2) When the material is unbalanced, the thrust exerted by the material on the two side rollers is different, so that the distance the two side rollers move along their axial direction is different. When the difference in the distance the two side rollers move relative to their initial position is greater than the second preset value, it indicates that the material is unbalanced. The distribution plate rotates to move the material on the conveyor belt, so that the material is evenly distributed on the conveyor belt during the conveying process, reducing the possibility of unbalanced material loading and conveyor belt deviation.

[0020] (3) Since the movement of the side roller along its axial direction can affect the size of the trough angle, the damping component slows down the movement of the side roller along its axial direction, slows down the change rate of the trough angle, reduces the sensitivity of the trough angle to the feed amount, and enables the trough angle to remain unchanged when the feed amount changes little, while also playing a role in shock absorption of the conveyor belt.

[0021] (4) The conveyor belt transports the material, the material moves relative to the pressure roller, the pressure roller rotates to apply pressure to the material on the conveyor belt, so that the material tends to be uniform in the height direction, so as to further reduce the possibility of material eccentricity and conveyor belt deviation.

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0044] like Figures 1 to 16 As shown, this embodiment of the invention provides a continuous conveying device for construction waste, including a support 100. A conveyor belt 101 is mounted on the support 100, along with a drive roller 102 and an idler roller assembly for running the conveyor belt 101. The idler roller assembly includes a bottom roller 103 and two side rollers 104. The axis of the bottom roller 103 is horizontal and perpendicular to the conveying direction of the conveyor belt 101. The two side rollers 104 are symmetrically arranged on both sides of a first plane. The first plane passes through the geometric center of the bottom roller 103 and is perpendicular to its axis. The end of each side roller 104 away from the bottom roller 103 is the outer end, and the end closer to the bottom roller 103 is the inner end. The outer end of the side roller 104 is higher than its inner end. This causes the conveyor belt 101 to form a trough angle. In the conveying direction of the conveyor belt 101, the distance between the outer end of the side roller 104 and the axis of the bottom roller 103 is greater than the distance between the inner end of the side roller 104 and the axis of the bottom roller 103. The diameter of the side roller 104 gradually decreases from its outer end to its inner end, and the generatrix of the circumferential surface of the side roller 104 is an outwardly convex arc. The part of the conveyor belt 101 that contacts the circumferential surface of the side roller 104 has a first slope. The side roller 104 can move along its axial direction and has a tendency to move towards the bottom roller 103. When the feed amount to the conveyor belt 101 is greater than the first preset value, the material pushes the side roller 104 away from the bottom roller 103, increasing the first slope and the trough angle.

[0045] When the feed rate to the conveyor belt 101 exceeds the first preset value, the material pushes the side roller 104 away from the bottom roller 103. At the same time, the conveyor belt 101 deforms, increasing the first slope and trough angle, reducing material waste caused by spillage and avoiding affecting equipment operation. The size of the trough angle is automatically adjusted by the amount of material fed to the conveyor belt 101, eliminating the need for manual adjustment and making it easy to control the degree of trough angle adjustment, thereby optimizing the running resistance of the conveyor belt 101.

[0046] Specifically, the support frame 100 is mounted on the ground, and there are two drive rollers 102 spaced apart. One of the drive rollers 102 is driven to rotate by an external power source to ensure stable operation of the conveyor belt 101. A corresponding power supply and controller are provided to control the operating conditions. The conveying direction of the conveyor belt 101 is... Figure 5 and Figure 13 As shown in the figure, it can be horizontal or at a certain angle to the horizontal plane. One side of the conveyor belt 101 is the feeding end, and the other side is the discharge end. Figure 13 In the diagram, the left side is the feeding end, and the right side is the discharging end. Both the bottom roller 103 and the side roller 104 are unpowered and rotate freely. When the conveyor belt 101 runs, it drives the bottom roller 103 and side roller 104 to rotate. The bottom roller 103 and side roller 104 support and guide the conveyor belt 101, and make the conveying section V-shaped, as shown below. Figure 3 As shown. The number and spacing of the idler roller assemblies can be selected and set according to the size of the conveyor belt 101. This application can be applied to fields such as mining, metallurgy, and construction waste treatment, and the construction waste to be conveyed is referred to as material.

[0047] It is worth noting that the trough angle of conveyor belt 101 is... Figure 7 The supplementary angle of the median angle α. A larger trough angle results in stronger anti-deviation and correction capabilities for the conveyor belt 101, making it less prone to material spillage. It also increases the maximum climbable angle of the conveyor belt 101 and reduces the adaptable turning radius, thereby improving overall machine performance. However, a larger trough angle also increases the running resistance of the conveyor belt 101, leading to increased equipment wear and energy consumption, and reduced service life. This application adjusts the trough angle appropriately based on the amount of material fed to the conveyor belt 101, thereby optimizing the running resistance of the conveyor belt 101 and avoiding the aforementioned adverse effects caused by excessive running resistance. In addition, the diameter of the side roller 104 gradually decreases from its outer end to its inner end, and the generatrix of the circumferential surface of the side roller 104 is an outwardly convex arc. The conveyor belt 101 has a certain elasticity, and its contact with the side roller 104 can be understood as an arc. The slope of the tangent corresponding to the midpoint of the contact arc is the first slope. When the feed rate increases to push the side roller 104 away from the bottom roller 103, the contact arc shortens and the slope of the tangent corresponding to the midpoint increases, the angle α decreases, and the groove angle increases.

[0048] It is understandable that, in the conveying direction of the conveyor belt 101, the distance between the outer end of the side roller 104 and the axis of the bottom roller 103 is greater than the distance between the inner end of the side roller 104 and the axis of the bottom roller 103. This means that the outer end of the side roller 104 is tilted forward, with a tilt angle of [missing information]. Figure 5 The midpoint angle β can be 1° to 3°. The side roller 104 generates a running resistance F on the conveyor belt 101. This force can be orthogonally decomposed into F1 and F2. F1 is perpendicular to the axis of the side roller 104 and forms an action-reaction pair with the force exerted by the conveyor belt 101 on the side roller 104, causing the side roller 104 to rotate. F2 is parallel to the running direction of the conveyor belt 101 and the two forces are opposite in direction, so that the conveyor belt 101 is subjected to an inward lateral thrust and does not deviate from the centerline, thereby reducing the possibility of the conveyor belt 101 running off-center. If the running off-center phenomenon has already occurred, the load on the side roller 104 will be redistributed, so that the running resistance F generated by the two side rollers 104 will differ. Specifically, F on the off-center side is larger, and F2 is also correspondingly larger, so that the conveyor belt 101 tends to move towards the first plane, thus achieving automatic correction. To further enhance the automatic correction capability, the drive roller 102 can be changed from the traditional cylindrical shape to a drum-shaped or double-conical drive roller with a larger middle and smaller ends, with a taper of 1:100. When the axis of the drive roller 102 is perpendicular to the conveying direction of the conveyor belt 101, the conveyor belt 101 tends to deviate towards the part with the larger diameter of the drive roller 102. By changing the cylindrical drive roller 102 to a drum-shaped or double-conical drive roller 102, the conveyor belt 101 tends to move towards the first plane, thus achieving automatic correction.

[0049] In one embodiment, the support 100 is provided with a uniform distribution component corresponding to the idler roller assembly. The uniform distribution component includes a uniform distribution plate 201. The side rollers 104 have an initial position. When in the initial position, the side rollers 104 are closest to the bottom rollers 103. When the difference in the distance that the two side rollers 104 have moved relative to the initial position is greater than a second preset value, the uniform distribution plate 201 rotates and its rotation axis is perpendicular to the axis of the bottom rollers 103 and the conveying direction of the conveyor belt 101. When the uniform distribution plate 201 rotates, it agitates and makes the material on the conveyor belt 101 evenly distributed.

[0050] In existing belt conveyor equipment, material misalignment increases the likelihood of conveyor belt 101 running off-track. When material is misaligned, the thrust exerted by the material on the two side rollers 104 is different, causing the two side rollers 104 to move different distances along their axial direction. When the difference in the distance the two side rollers 104 move relative to their initial position is greater than a second preset value, it indicates that the material misalignment is significant. The distribution plate 201 rotates to agitate the material on the conveyor belt 101, thereby ensuring that the material is evenly distributed on the conveyor belt 101 during the conveying process, reducing the likelihood of material misalignment and conveyor belt 101 running off-track.

[0051] Before rotation, the length direction of the uniform distribution plate 201 can be parallel to the conveying direction of the conveyor belt 101 to reduce the impact of the uniform distribution plate 201 on the material on the conveyor belt 101.

[0052] In one embodiment, see Figure 8 and Figure 11 The roller assembly also includes a first piston cylinder 202 corresponding to the side roller 104, and a first chamber 203 is formed inside the first piston cylinder 202. The distribution assembly also includes two coaxially arranged second piston cylinders 204, and a second chamber 205 is formed inside the second piston cylinder 204. The first chamber 203 and the second chamber 205 are connected and filled with a flowing medium. The second chamber 205 is provided with a moving member 206 that can move along the axial direction of the second piston cylinder 204. An intermediate member 207 connected to the distribution plate 201 is provided between the two moving members 206. When the side roller 104 moves away from the bottom roller 103, the first chamber 203 is compressed and the moving member 206 is pushed by the flowing medium. The moving member 206 applies a force to the intermediate member 207. When the difference in the distance that the two side rollers 104 have moved relative to their initial positions is greater than a second preset value, the difference in the force applied by the two moving members 206 to the intermediate member 207 is greater than a third preset value, and the distribution plate 201 rotates.

[0053] When the feed rate to conveyor belt 101 exceeds a first preset value, the material pushes the side rollers 104 away from the bottom rollers 103, increasing the trough angle. Simultaneously, the first chamber 203 is compressed, and the moving parts 206 are pushed by the flowing medium. The moving parts 206 exert a force on the intermediate parts 207. When the difference in the distance the two side rollers 104 have moved relative to their initial positions exceeds a second preset value, the difference in the force exerted by the two moving parts 206 on the intermediate parts 207 exceeds a third preset value. The distribution plate 201 rotates to agitate the material on the conveyor belt 101, thereby ensuring that the material is evenly distributed on the conveyor belt 101 during the conveying process. The change in the feed rate to conveyor belt 101 causes the two side rollers 104 and the two moving parts 206 to move, achieving the rotation of the distribution plate 201 without additional power.

[0054] Among them, see Figure 7 and Figure 8The support 100 is provided with a first base 108 and a second base 109. The roller assembly is disposed on the second base 109. Specifically, the second base 109 is provided with three C-shaped roller frames, which are used to support the bottom roller 103 and two side rollers 104 respectively. For the side rollers 104, their roller frames are provided with side shafts 105. The side rollers 104 are coaxial with the side shafts 105 and can rotate. At the same time, the side rollers 104 can move along the side shafts 105. The first piston cylinder 202 is formed on the side shafts 105. The first piston cylinder 202 and the side roller 104 are coaxially arranged on the outer side. A top sleeve 208 is provided between the first piston cylinder 202 and the side roller 104. The inner side of the top sleeve 208 abuts against the side roller 104, and a convex ring is formed on the outer side of the top sleeve 208, extending into the first piston cylinder 202. The convex ring is sealed and slidably connected to the inner wall of the first piston cylinder 202. A first compression spring 209 is also provided between the top sleeve 208 and the first piston cylinder 202. The first compression spring 209 is used to make the side roller 104 tend to move closer to the bottom roller 103. The side of the first piston cylinder 202 away from the side roller 104 is sealed and forms a first interface 210. See also Figure 11 The uniform distribution assembly also includes a housing 211, with two second piston cylinders 204 disposed opposite to each other on the housing 211 and communicating with its interior. A second port 212 is provided at the end of each second piston cylinder 204 away from the housing 211. The second port 212 is connected to the first port 210 via a pipeline, thereby communicating between the first chamber 203 and the second chamber 205. The flowing medium can be hydraulic oil.

[0055] In one embodiment, the intermediate member 207 is a cam, and the rotation axis of the intermediate member 207 is offset from the axis of the second piston cylinder 204. The moving member 206 has a fixed end 213 and a telescopic end 214. The telescopic end 214 and the fixed end 213 can extend and retract relative to each other along the axial direction of the second piston cylinder 204. The fixed end 213 can move along the axial direction of the second piston cylinder 204. The telescopic end 214 contacts the outer contour of the intermediate member 207.

[0056] When the feed rate to the conveyor belt 101 is greater than the first preset value, the material pushes the side roller 104 away from the bottom roller 103, increasing the trough angle. At the same time, the first chamber 203 is compressed and the moving part 206 is pushed by the flowing medium. The moving part 206 applies a force to the intermediate part 207 through its telescopic end 214. When the difference in the distance that the two side rollers 104 have moved relative to their initial positions is greater than the second preset value, the difference in the force applied to the intermediate part 207 by the telescopic ends 214 of the two moving parts 206 is greater than the third preset value. Due to the telescopic structure of the moving part 206, it can push the intermediate part 207 to rotate around its axis, thereby driving the uniform distribution plate 201 to rotate.

[0057] Middleware 207 has a symmetrical structure. Initially, as follows: Figure 11As shown, the intermediate part 207 is symmetrical from left to right. The lower contour of the intermediate part 207 protrudes outward and is provided with a rotation axis. The contours of other parts of the intermediate part 207 can be circular. The size of the intermediate part 207 can be selected and set as needed to avoid motion interference with the housing 211. The fixed end 213 is sealed and slidably connected to the inner wall of the second piston cylinder 204. A second compression spring 215 is provided between the fixed end 213 and the telescopic end 214. The second compression spring 215 is used to make the telescopic end 214 tend to extend out of the fixed end 213 so that the telescopic end 214 contacts the outer contour of the intermediate part 207.

[0058] In one embodiment, see Figure 8 The first piston cylinder 202 is provided with a damping element, which is used to slow down the movement of the side roller 104 along its axial direction.

[0059] Since the movement of the side roller 104 along its axial direction can affect the size of the trough angle, the damping component slows down the movement of the side roller 104 along its axial direction, slows down the rate of change of the trough angle, reduces the sensitivity of the trough angle to the influence of the feed rate, and enables the trough angle to remain unchanged when the feed rate changes little, while also playing a role in shock absorption of the conveyor belt 101.

[0060] The first piston cylinder 202 has an opening on the side near the side roller 104 and is provided with an end cap 216. The end cap 216 abuts against the convex ring to limit the sliding distance of the top sleeve 208 along the first piston cylinder 202. In addition, when the side roller 104 moves along its axial direction, a third chamber is formed between the convex ring of the top sleeve 208 and the end cap 216. The damping element is a plurality of connecting holes 217 opened on the end cap 216. The connecting holes 217 are used to connect the third chamber with the outside air. The diameter of the connecting holes 217 is small, for example, it can be 1 / 20 to 1 / 10 of the diameter of the end cap 216. When the side roller 104 moves along its axial direction, the volume of the first chamber 203 decreases and the volume of the third chamber increases. The small diameter connecting holes 217 will slow down the increase in the volume of the third chamber, thereby slowing down the movement of the side roller 104 along its axial direction.

[0061] In one embodiment, when the difference in distance between the two side rollers 104 and their initial positions is greater than a second preset value, the distribution plate 201 rotates and moves toward the conveyor belt 101, and the distribution plate 201 has a tendency to move away from the conveyor belt 101.

[0062] When the material is heavily unbalanced, the distribution plate 201 rotates and moves toward the conveyor belt 101 to agitate the material on the conveyor belt 101. When the unbalanced material load decreases to a certain value, the distribution plate 201 moves away from the conveyor belt 101 to reset.

[0063] Among them, see Figure 2 , Figures 9 to 11 as well as Figure 14A dust cover 106 is provided on the support 100, and a cylinder 218 is provided on the dust cover 106. The housing 211 is fixed to the cylinder 218. A spiral groove is provided on the inner wall of the cylinder 218. A rotating cylinder 219 is inserted into the cylinder 218. A uniform distribution plate 201 is vertically fixed at one end of the rotating cylinder 219. A guide pin 220 is provided on the outer wall of the rotating cylinder 219. The guide pin 220 slides along the spiral groove. A rotating shaft 221 is fixed on the intermediate part 207. The intermediate part 207 can rotate around the rotating shaft 221. The rotating shaft 221 extends out of the housing 211 and is inserted into the rotating cylinder 219 from the other end. The rotating shaft 221 and the rotating cylinder 219 are connected by a key and a keyway so that they can move axially and rotate synchronously. A first tension spring 222 is provided between the housing 211 and the other end of the rotating cylinder 219. The first tension spring 222 is used to make the uniform distribution plate 201 tend to move away from the conveyor belt 101. When the intermediate component 207 and the rotating shaft 221 rotate synchronously, the rotating drum 219 and the uniform distribution plate 201 rotate synchronously. At the same time, the guide pin 220 slides along the spiral groove, and the rotating drum 219 moves relative to the rotating shaft 221, thereby causing the uniform distribution plate 201 to rotate and move towards the conveyor belt 101, and be reset by the first tension spring 222.

[0064] In one embodiment, see Figure 16 The support 100 is provided with a pressure roller 223. The axis of the pressure roller 223 is parallel to the axis of the bottom roller 103. When the pressure roller 223 rotates, it can apply pressure to the material on the conveyor belt 101. The pressure roller 223 is spaced apart from the conveyor belt 101 and has a tendency to move closer to the conveyor belt 101.

[0065] The conveyor belt 101 conveys the material, which moves relative to the pressure roller 223. The pressure roller 223 rotates to apply pressure to the material on the conveyor belt 101, making the material more uniform in the height direction, so as to further reduce the possibility of material uneven loading and conveyor belt 101 running off-center.

[0066] The pressure roller 223 is mounted on the dust cover 106 and close to the feeding end of the conveyor belt 101. Specifically, a roller frame is slidably mounted on the dust cover 106, with the sliding direction perpendicular to the conveying direction of the conveyor belt 101 and the axial direction of the pressure roller 223. A second tension spring 224 is provided between the dust cover 106 and the roller frame of the pressure roller 223. The second tension spring 224 is used to make the pressure roller 223 tend to move closer to the conveyor belt 101, so that after feeding, the pressure roller 223 applies pressure to the material on the conveyor belt 101, making the material tend to be uniform in the height direction.

[0067] In one embodiment, see Figure 1 , Figure 2 and Figure 14 The support 100 is equipped with a dust cover 106, which is located above the conveyor belt 101.

[0068] Since construction waste will cause dust to splash during feeding and conveying, a dust cover 106 is installed above the conveyor belt 101 to reduce the amount of dust splashing and improve the environmental protection level of the equipment.

[0069] In one embodiment, see Figure 15 The support frame 100 is equipped with a cleaning component 107. The conveyor belt 101 includes a conveying section and a return section. The cleaning component 107 is used to clean the return section.

[0070] The cleaning component 107 is a roller-shaped structure. The cleaning component 107 is set at the discharge end of the conveyor belt 101, and the cleaning roller is driven to rotate by an external power source of the drive roller 102. The driving method is belt drive.

[0071] In one embodiment, see Figure 4 and Figure 6 The bracket 100 is provided with a first base 108 and a second base 109. The first base 108 and the second base 109 can rotate relative to each other and the rotation axis is parallel to the axis of the bottom roller 103. The roller assembly is disposed on the second base 109. A limiting member 110 is provided between the first base 108 and the second base 109. The limiting member 110 is used to limit the rotation angle of the first base 108 and the second base 109.

[0072] The first base 108 and the second base 109 can rotate relative to each other. During equipment debugging, the forward tilt angle of the side roller 104 can be initially adjusted, and the rotation angle of the first base 108 and the second base 109 can be limited by the limiting member 110, so that the side roller 104 can maintain the current forward tilt angle, which can reduce the possibility of the conveyor belt 101 running off-center to a certain extent. When the equipment is running, when the feed rate increases, the trough angle increases, which can further reduce the possibility of the conveyor belt 101 running off-center.

[0073] The working principle of this invention is as follows:

[0074] Material is fed from the feeding end onto the conveyor belt 101. Under the action of the conveyor belt 101, the material moves toward the discharge end. The pressure roller 223 rotates to apply pressure to the material on the conveyor belt 101, so that the material tends to be uniform in the height direction, reducing the possibility of material uneven loading and conveyor belt 101 running off-center.

[0075] When the feed rate to the conveyor belt 101 exceeds the first preset value, the material pushes the side roller 104 away from the bottom roller 103. At the same time, the conveyor belt 101 deforms, and the first parameter and trough angle increase, reducing material waste caused by spillage and avoiding affecting equipment operation. The size of the trough angle is automatically adjusted by the amount of material fed to the conveyor belt 101. There is no need for manual adjustment and the degree of adjustment of the trough angle is easy to control, thereby optimizing the running resistance of the conveyor belt 101.

[0076] As the side rollers 104 move away from the bottom rollers 103, the first chamber 203 is compressed and the moving part 206 is pushed by the flowing medium. The moving part 206 applies a force to the intermediate part 207 through its telescopic end 214. When the material is unevenly loaded, the thrust exerted by the material on the two side rollers 104 is different, so that the distance the two side rollers 104 move along their axial direction is different. When the difference in the distance the two side rollers 104 move relative to their initial position is greater than the second preset value, it indicates that the material is unevenly loaded. The difference in the force exerted by the telescopic ends 214 of the two moving parts 206 on the intermediate part 207 is greater than the third preset value. Due to the telescopic structure of the moving part 206, it can push the intermediate part 207 to rotate around its axis, thereby driving the uniform distribution plate 201 to rotate and move towards the conveyor belt 101, so as to agitate the material on the conveyor belt 101, thereby making the material evenly distributed on the conveyor belt 101 during the conveying process, reducing the possibility of uneven material loading and the conveyor belt 101 running off-center.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
