Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of material sorting. More specifically, the present utility model provides a sorting machine. Background Art

[0002] In modern industrial production, material sorting equipment is one of the indispensable important equipment. The equipment is widely used in industries such as mining, smelting, and chemical engineering for sorting ores; it can also be used for garbage sorting to sort different types of garbage; it can also be used for food sorting. It can sort materials according to the type or quality of the materials, improving resource utilization efficiency and production benefits. The sorting machine conveys materials through a conveying mechanism, identifies the types of materials through a detection mechanism, and sorts the materials through a separation mechanism according to the types of materials. In some related technologies, after the materials are thrown out from the conveying mechanism and pass through the detection mechanism, the separation mechanism then sorts the materials in the falling state; or after passing through the detection mechanism, the materials are thrown out from the conveying mechanism, and the separation mechanism also sorts the materials in the falling state. Since the materials are in a free-fall state, the falling speed will continuously increase, and the separation mechanism may not be able to capture the materials in time, resulting in sorting errors.

[0005] In some embodiments, the discharge port is located directly above the air inlet along the direction of gravity, and the wind power assembly is located directly below the air inlet along the direction of gravity, so that the materials are thrown upward along the direction of gravity through the discharge port.

[0006] In some embodiments, the separation mechanism is located on the side of the material thrown upward along the gravity direction from the discharge port, and is used to apply a force to the material from the side of the material to change the trajectory of the material.

[0008] In some embodiments, the separation mechanism includes: a first separation mechanism for applying a force to the materials of the first category to change the trajectory of the materials of the first category so as to fall into the first recovery area, where the first recovery area is one of the multiple recovery areas; a second separation mechanism disposed above the first separation mechanism for applying a force to the materials of the second category to change the trajectory of the materials of the second category so as to fall into the second recovery area, where the second category is a material category different from the first category, and the second recovery area is one of the multiple recovery areas and is different from the first recovery area.

[0009] In some embodiments, the discharge port is located above the air inlet along the first direction, where the first direction forms an angle with the gravity direction, and the angle is greater than 0 degrees and less than 90 degrees; the wind force assembly is located below the air inlet along the first direction, so that the material is thrown upward along the first direction through the discharge port.

[0011] In some embodiments, the separation mechanism includes: a first downward separation mechanism for applying a force to the materials of the first category to change the trajectory of the materials of the first category so as to fall into the first recovery area, where the first recovery area is one of the multiple recovery areas.

[0012] In some embodiments, the separation mechanism further includes: a second downward separation mechanism disposed on one side of the first downward separation mechanism for applying a force to the materials of the second category to change the trajectory of the materials of the second category so as to fall into the second recovery area, where the second category is a material category different from the first category, and the second recovery area is one of the multiple recovery areas and is different from the first recovery area.

[0013] In some embodiments, the separation mechanism includes: a blowing assembly for changing the trajectory of materials by blowing air to the materials; and / or, a push plate assembly for changing the trajectory of materials by hitting the materials with the push plate.

[0021] To solve the foregoing problems, the present utility model provides a sorting machine 100 for sorting materials 200, so as to identify and sort the materials 200 when the materials 200 are at a slower speed, and improve the sorting accuracy of the materials 200. The materials 200 disclosed in this disclosure can be ores, which may contain coal mines and gangues, and the two can be distinguished by the sorting machine 100; or the sorting machine 100 can sort concentrate, coarse ore, and gangue in coal mines. The materials 200 can also be different types of garbage, or different types and grades of food ingredients. In this disclosure, the particle size of the materials can be 5 - 30 mm. For example, the particle size of the materials can be 20 mm.

[0022] As Figure 1 、 Figure 2As shown, the sorting machine 100 of the present disclosure may include: a conveying mechanism 10, a detection mechanism 20, a separation mechanism 30, and a recovery mechanism 40. In some embodiments, the sorting machine 100 may further include a control module, which may be communicatively connected to the conveying mechanism 10, the detection mechanism 20, the separation mechanism 30, etc., and can control the separation mechanism 30 to sort materials according to the detection results of the detection mechanism 20. In terms of specific implementation manners, the control module may be implemented in various suitable ways. For example, the control module may include a control product implemented by a general-purpose processor (CPU) and / or a dedicated processor. In some scenarios, the control module of the present utility model may also be implemented by a Programmable Logic Controller (PLC).[[ID=!]]

[0023] In the embodiments of the present disclosure, the material 200 may include multiple categories, which are conveyed and thrown out by the conveying mechanism 10, the multiple categories are identified by the detection mechanism 20, and then the separation mechanism 30 is used to make different categories of materials form different trajectories and fall into different recovery areas of the recovery mechanism 40 to achieve sorting. In the embodiments of the present disclosure, two categories of materials 200, namely the first category of material 200a and the second category of material 200b, are taken as examples for illustration, such as coal mines and gangue, but it is not limited that the sorting machine of the embodiments of the present disclosure can only identify the above two materials.

[0024] The conveying mechanism 10 may be used to receive and convey the material 200, and includes an air inlet 11, a discharge port 12, and a wind power assembly 13. The conveying mechanism 10 may be a hopper, with an inlet formed on the upper side, and the inlet is used to receive the input material 200. The hopper of the conveying mechanism 10 may include an inclined section, and after the material 200 enters, it slides obliquely towards the bottom along the inclined section of the hopper. In some embodiments, the cross-section of the inclined section may be relatively narrow compared to the inlet, and on the premise of allowing the material 200 to pass, a large amount of the material 200 is prevented from directly stacking at the bottom position of the conveying mechanism 10, affecting subsequent throwing. In some embodiments, the conveying mechanism 10 may be provided with a vibration device for generating vibration to controllably convey the material 200.

[0025] An air inlet 11 may be provided at the bottom of the conveying mechanism 10 for air intake. The air inlet 11 is arranged to allow gas to pass through. In some embodiments, it may be an open setting, and the passing material 200 is blown upward by the wind force to prevent it from falling. In other embodiments, the conveying mechanism 10 may be provided with a filter screen at the air inlet 11 to prevent the material 200 from falling. While the filter screen prevents the material 200 from falling, it allows the gas to pass through.

[0026] The discharge port 12 can be arranged opposite to the air inlet 11 and is located above the air inlet 11. It should be noted that the discharge port 12 can be directly above the air inlet 11 along the gravity direction x (as Figure 1 shown), or can be obliquely above the feed inlet 11 (as Figure 2 shown). The discharge port 12 is arranged above the air inlet 11, so that the movement mode of the material 200 thrown through the discharge port 12 can be a vertical upward throw movement or an oblique upward throw movement.

[0027] The wind power assembly 13 is arranged below the air inlet 11. It should be noted that the wind power assembly 13 can be directly above the air inlet 11 along the gravity direction x (as Figure 1 shown), or can be obliquely below the feed inlet 11 (as Figure 2 shown). The wind power assembly 13 is used to blow air into the conveying mechanism 10 through the air inlet 11, so that the material 200 located at the bottom of the conveying mechanism 10 at the air inlet 11 receives the wind force applied by the wind power assembly 13 and is thrown upward from the discharge port 12, forming a vertical upward throw movement or an oblique upward throw movement. In the embodiment of the present disclosure, the wind power assembly 13 can include a blower to provide wind force at the air inlet 11 of the conveying mechanism 10 to blow the material 200 to a preset height. In some embodiments, the wind power assembly 13 can quickly blow out the material 200, so that before the next material 200 at the same position reaches the air outlet 11, the previous material has provided sufficient initial velocity to the material based on the wind force action time, and the material can realize the aforementioned vertical upward throw and oblique upward throw movements based on the initial velocity of the material, thereby avoiding the wind force shielding of the subsequent material to the previous material. In some embodiments, after the material 200 is thrown out, it can complete the movement of the predetermined trajectory without the need for the wind power assembly 13 to provide continuous wind force. In some other embodiments, the material 200 can reach the balance position of gravity and wind force with a speed close to 0 under the continuous action of the upward wind force. In some embodiments, the angle of the inclined section of the conveying mechanism 10 is relatively gentle and close to the horizontal plane, so that the feeding speed is reduced to avoid a large amount of material 200 reaching the bottom of the conveying mechanism 10 at the same time. In some embodiments, the wind power assembly 13, the air inlet 11 and the discharge port 12 can be located on a straight line. With such a setting, the wind force loss of the wind power assembly 13 is lower, and the material 200 can be quickly blown out.

[0028] The detection mechanism 20 can be arranged above the discharge port 12 of the conveying mechanism 10 for detecting the category of the material 200 thrown from the discharge port 12.

[0029] In some embodiments, such as Figure 1 、 Figure 2As shown, the detection mechanism 20 may include an image sensor 22 and an optomechanics device 21. The optomechanics device 21 may emit laser, X-ray, etc. The optomechanics device 21 may irradiate the material 200 in the detection area of the detection mechanism 20 and transmit the image to the image sensor 22. The image sensor 22 may transmit the signal to the control module. After calculation, the control module controls the separation mechanism 30 to perform sorting. As Figure 1 and Figure 2 shown, the image sensor 22 and the optomechanics device 21 may be respectively located on both sides of the movement trajectory of the material 200 after being thrown out from the discharge port 12.

[0030] In some embodiments, the optomechanics device 21 may be an X-ray emitting end for emitting X-rays; the image sensor 22 may be an X-ray receiver for receiving the X-rays passing through the material 200. Then, the type of the material is judged according to the received X-rays. The X-ray detection component can detect the size, density and atoms of the material, wherein the density and / or atoms can reflect the type of the material 200 and can be selected as the type parameters. In other embodiments, the detection mechanism 20 may include a camera, which can detect the shape, size and color of the material 200, wherein the color can reflect the type of the material and can be selected as the type parameter. The camera can take pictures of the passing material 200 so that the control module can identify the size, type, etc. of the material 200 based on the picture results through image recognition technology. It should be noted that, in addition to being arranged above the conveying mechanism 1 to detect the materials in conveying, the detection mechanism 20 of this embodiment can also be arranged between the conveying mechanism 1 and the separation mechanism 3 to detect the released materials.

[0031] The separation mechanism 30 is arranged above the detection mechanism 20, and it can be directly above the detection mechanism 20 in the positive direction of the gravity direction x or obliquely above. It is used to apply a force to the material 200 based on the category of the material 200 to change the trajectory of the material 200. Specifically, after the material 200 is thrown out from the discharge port 12, the trajectory of the material 200 first passes through the detection mechanism 20, enabling the detection mechanism 20 to detect the category of the material 200, and then passes through the separation mechanism 30, enabling the separation mechanism 30 to apply a force to the material. It should be noted that the separation mechanism 30 can apply a force to the material that moves near the separation mechanism 30, but it is not necessary to apply a force to each material. In some embodiments, when the material 200 passes through the separation mechanism 30, the separation mechanism 30 can apply a force to a certain type of material to change the movement trajectory of the material, so as to reach the corresponding recovery area of the recovery mechanism 40; and does not apply a force to another type of material, so that this type of material reaches the corresponding recovery area of the recovery mechanism 40 based on the original movement trajectory. In other embodiments, the separation mechanism 30 can apply different forces to different types of materials, so that different types of materials form different trajectories and fall into different recovery areas of the recovery mechanism 40. In still other embodiments, the separation mechanism can apply forces to different types of materials from different positions, so that different types of materials form different trajectories and fall into different recovery areas of the recovery mechanism 40.

[0032] The recovery mechanism 40 can be arranged below the separation mechanism 30, and it can be directly below or obliquely below the separation mechanism 30 along the gravity direction x. The recovery mechanism 40 can include multiple recovery areas, which are respectively used to receive different types of materials 200 separated by the separation mechanism 30.

[0033] In the embodiments of the present disclosure, the discharge port 12 is arranged above the air inlet 11, so that the movement mode of the material 200 thrown out through the discharge port 12 can be a vertical upward throw movement or an oblique upward throw movement. Therefore, within at least a period of time after the material 200 is thrown out (before reaching the highest point), at least the value of the velocity in the vertical direction (i.e., the gravity direction) gradually decreases, so that the detection and sorting of the material 200 can be carried out in a relatively low-speed state after the material 200 is thrown out, thereby ensuring the accuracy and reliability of the identification and sorting of the material.

[0034] In some embodiments, the separation mechanism 30 can include: a blowing component, which is used to change the trajectory of the material 200 by blowing air to the material 200. Gas can be ejected through the blowing component and act on the material in the air to change the trajectory of the material. Through the blowing method, the sorting of the material can be carried out quickly and efficiently.

[0035] In some exemplary embodiments, the blowing assembly may include: a valve plate including one or more rows of air blowing holes; and a solenoid valve, the air outlet of the solenoid valve communicating with the air blowing holes, and its inlet for receiving pressurized gas. For example, in some embodiments, the separator 100 may further include a gas supply assembly connected to the inlet of each solenoid valve.

[0036] In some embodiments, the separation mechanism 30 may also include: a push plate assembly for hitting the material 200 with the push plate to change the trajectory of the material 200. A relatively large acting force can be provided through the push plate, enabling more accurate separation of some materials with larger particle sizes and greater weights. In some embodiments, the separation mechanism 30 may simultaneously include a blowing assembly and a push plate assembly, and the materials are separated by the two mechanisms.

[0037] This disclosure uses the blowing assembly as an example for illustration, but is not limited to using the blowing assembly for separation.

[0038] In some embodiments, the separation mechanism may further include a baffle assembly for blocking the material to change the trajectory of the material. In the embodiments of this disclosure, a fixed baffle may be provided on the flight trajectory of the material, and the material is blocked by the baffle into a certain recovery area. This embodiment can cooperate with other components of the separation mechanism 30, such as cooperating with the blowing assembly. By the blowing assembly, the trajectories of certain types of materials are changed, and for certain types of materials whose trajectories are not changed, they can be made to fall into the corresponding recovery areas by the blocking of the baffle assembly. By providing the baffle assembly, the horizontal distance of the material flight can be shortened, and the space occupied by the separator 100 can be reduced.

[0039] In some embodiments, the separation mechanism 30 may be arranged to apply a force to the material 200 when the material 200 reaches the highest point or before the material 200 reaches the highest point. In the embodiments of this disclosure, the separation mechanism 30 may be arranged at the highest point position or the ascending section of the trajectory of the material 200, so that the material 200 is in a position where it can be acted on by the separation mechanism 30 when it reaches the highest point or before it reaches the highest point. In this embodiment, before the material 200 reaches the separation mechanism 30, at least the magnitude of the velocity in the vertical direction is in a gradually decreasing process. Therefore, the separation mechanism 30 can apply a force to the material or a certain type of material in a state where the velocity of the material 200 is small, thereby ensuring the reliability of separation.

[0040] In some embodiments, as Figure 1 shown, the discharge port 12 may be located directly above the air inlet 11 along the gravity direction x, and the wind power assembly 13 is located directly below the air inlet 11 along the gravity direction x, so that the material 200 is thrown upward along the gravity direction x through the discharge port 12.

[0041] As Figure 1As shown, the wind power assembly 13 can blow the material 200 upward. The detection mechanism 20 can be located above the discharge port 12 and is used to detect the material 200 blown vertically upward. The separation mechanism 30 can be located above the detection mechanism 20. For example, it can be located on one side of a preset position (the highest point of the material, the gravity-wind balance position, or other positions), approximately at the position where the material speed decreases or approaches zero. It can be seen that there is a certain distance between the position of the detection mechanism 20 and the separation mechanism 30, leaving time for making a judgment based on the detection result of the detection mechanism 20 and controlling the separation mechanism 30 to perform corresponding operations. In addition, since the material 200 moves upward from the detection mechanism 20 to the separation mechanism 30, under the action of gravity, the speed of the material 200 becomes slower and slower during this period, which is beneficial for the separation mechanism 30 to make operations in a timely manner and can also increase the time for the separation mechanism 30 to apply a force to the material, thereby improving the accuracy of sorting.

[0042] As Figure 1 shown, after the material 200 slides to the bottom of the conveying mechanism 10, it is pushed by the blowing force of the wind power assembly 13 and is blown straight from the discharge port 12 into the air. In the upward movement trajectory of the material 200, the optical machine 31 and the image sensor 22 are arranged horizontally in the first stage. During this process, the speed of the material 200 is relatively fast. The optical machine 21 irradiates the material and transmits the image to the image sensor 22. The image sensor 21 then transmits a signal to the background program (control module). After calculation by the background program, the separation mechanism 30 is controlled to sort the material. In the second stage, during the upward movement of the material, the movement speed gradually slows down until it reaches the highest point. At this time, the gravity and the blowing force of the material reach a balance. This area can be the area for sorting, that is, the preset position. The highest point can also be the highest point that the material 200 reaches after being applied with wind force by the wind power assembly 13, moving upward based on inertia and gradually decelerating based on gravity.

[0043] In some embodiments, as Figure 1 shown, the separation mechanism 30 can be located on the side of the material 200 thrown upward along the gravity direction x from the discharge port 12 and is used to apply a force to the material 200 from the side of the material 200 to change the trajectory of the material 200. By applying a force to the material in the side direction, it is possible to avoid the interference of the separation mechanism 30 itself on the flight trajectory of the material and can conveniently give the material a horizontal component of velocity, changing the flight trajectory of the material so as to fall into the corresponding recovery area.

[0044] In some embodiments, the separation mechanism 30 may include: a single separation mechanism (not shown in the figures), configured to apply a first acting force to the materials 200a of the first category, so as to change the trajectory a of the materials 200a of the first category and make them fall into the first recovery area 41, where the first recovery area 41 is one of a plurality of recovery areas; the single separation mechanism is further configured to apply a second acting force to the materials 200b of the second category, so as to change the trajectory b of the materials 200b of the second category and make them fall into the second recovery area 42, where the second category is a material category different from the first category, and the second recovery area 42 is one of a plurality of recovery areas and is different from the first recovery area 41. In the embodiments of the present disclosure, a single separation mechanism may be provided laterally. By applying acting forces of different magnitudes to different types of materials, different types of materials form different trajectories and fall into different recovery areas, thereby realizing sorting. In this way, the number of components of the separation mechanism 30 can be reduced, the cost can be lowered, and the space occupation can be reduced.

[0045] As Figure 1 , Figure 2 shown, in some embodiments, the recovery mechanism 40 of the present disclosure may include a first recovery area 41 and a second recovery area 42, which are respectively configured to recover different types of materials. Compared with the first recovery area 41, the second recovery area 42 may be located at a position far from the conveying mechanism 10. The recovery mechanism 40 of the present disclosure may also include more recovery areas to classify and recover more categories of materials. The plurality of recovery areas may be arranged in a horizontal direction from near to far relative to the conveying mechanism 10.

[0046] In some embodiments, as Figure 1 shown, the separation mechanism 30 may include: a first separation mechanism 31, configured to apply an acting force to the materials 200a of the first category, so as to change the trajectory a of the materials 200a of the first category and make them fall into the first recovery area 41, where the first recovery area 41 is one of a plurality of recovery areas; a second separation mechanism 32, disposed above the first separation mechanism 31, configured to apply an acting force to the materials 200b of the second category, so as to change the trajectory b of the materials 200b of the second category and make them fall into the second recovery area 42, where the second category is a material category different from the first category, and the second recovery area 42 is one of a plurality of recovery areas and is different from the first recovery area 41. In the embodiments of the present disclosure, as Figure 1As shown, two separation mechanisms can be arranged vertically, namely, a first separation mechanism 31 and a second separation mechanism 32. After the material 200 is thrown out from the discharge port 13, after being identified by the detection mechanism 20, it continues to move upward. Before reaching the highest point, it passes through the area where the first separation mechanism 31 can apply a force. According to the detection result of the detection mechanism 20, the first separation mechanism 31 can apply a force to the material 200a of the first category. For example, by jetting gas, the gas is jetted onto the material 200a of the first category, so that the material 200a of the first category moves along the trajectory a and falls into the first recovery area 41. On the other hand, for the material 200b of the second category, the first separation mechanism 31 does not apply a force, so that the material 200b of the second category continues to move upward and reaches the area where the second separation mechanism 32 located above can apply a force. The second separation mechanism 32 applies a force to the material 200b of the second category. For example, by jetting gas, the gas is jetted onto the material 200b of the second category, so that the material 200b of the second category moves along the trajectory b and falls into the second recovery area 42. By arranging the first separation mechanism 31 and the second separation mechanism 32, forces are applied to different types of materials at different positions to change the trajectories of the materials, and the control is simpler.

[0047] In some embodiments, the first separation mechanism 31 and the second separation mechanism 32 can respectively provide different forces, so that different forces can be provided from different positions, and more trajectories of the materials can be realized to sort more types of materials. In some scenarios, the highest points of materials with different weights are different. The first separation mechanism 31 and the second separation mechanism 32 can respectively sort materials with different weights. The materials with different weights can both include two categories. The first separation mechanism 31 and the second separation mechanism 32 can respectively sort the two categories of materials by two forces, so as to achieve the purpose of accurately sorting materials with different weights.

[0048] In some embodiments, the blowing assembly can provide a first blowing force and a second blowing force, which can be specifically set according to the properties of the material such as mass, shape, density, color, etc., as long as the purpose of sorting the two materials can be achieved. For example, they can be respectively set as long blowing and short blowing. For example, in some embodiments, the materials in the lower part of the preset position are lighter in weight and require less gas volume for the spray holes, while the materials in the upper part of the preset position are heavier in weight and require more gas paths for the spray holes. Each spray hole can perform long blowing and short blowing, and the materials can be sorted into different recovery areas according to the different identifications of the control module.

[0049] In some embodiments, the first separation mechanism 31 and the second separation mechanism 32 perform sorting by means of jet blowing. The jet blowing directions can be parallel, applying forces at the same angle to the material, such as horizontal jet blowing. The jet blowing directions can also be non-parallel, applying forces at different angles to the material to ensure that the movement trajectories of different types of materials do not interfere with each other.

[0050] In other embodiments, more separation mechanisms can be included in addition to the first separation mechanism 31 and the second separation mechanism 32, arranged at different positions in the vertical direction to achieve sorting of more types of materials.

[0051] In some embodiments, as Figure 2 shown, the discharge port 12 can be located above the air inlet 11 along the first direction y, where the first direction y forms an angle with the gravity direction x, and the angle is greater than 0 degrees and less than 90 degrees; the wind power assembly 13 is located below the air inlet 11 along the first direction y, so that the material 200 is thrown upward along the first direction y through the discharge port 12.

[0052] As Figure 2 shown, the material 200 first enters the conveying mechanism 10 and slides obliquely down to the bottom along the slope of the conveying mechanism 10. An air inlet 11 is provided at the bottom, and a wind power assembly 13 is arranged. The air outlet of the wind power assembly 13 can be arranged obliquely along the first direction y, and the material 200 sliding to the bottom can be kept moving in the form of an oblique upward throw. The angle between the throwing direction and the gravity direction x can be between 0 and 90 degrees. When it is closer to 0 degrees, the horizontal speed is smaller and the flying distance of the material is shorter, and the wind power provided by the wind power assembly 13 can be smaller; when it is closer to 90 degrees, the horizontal speed is higher and the flying distance of the material is far, which is convenient for the setting of the recovery area. In the embodiments of the present disclosure, the angle can be between 30 and 60 degrees, for example, it can be 30 degrees, 45 degrees, 60 degrees, etc. During the climbing process of the material 200, under the action of gravity, the speed in the gravity direction x decreases with the increase of height. The optical machine 21 and the image sensor 22 of the detection mechanism 20 can be distributed perpendicular to the trajectory direction of the material 200, or can be arranged along the gravity direction x (as Figure 2 shown). When the material 200 reaches the highest height and gradually falls downward, the separation mechanism 30 can be set when the material 200 reaches the highest point or does not reach the highest point, so as to ensure that the material is sorted by the separation mechanism 30 in a lower speed state, improving the sorting accuracy.

[0053] In some embodiments, as Figure 2As shown, the separating mechanism 30 is used to apply a downward force to the material 200 from above the material 200 to change the trajectory of the material 200. In the embodiments of the present disclosure, the separating mechanism 30 can be arranged above the gravity direction x of the initial trajectory of the material 200, and a force is applied to the material in the downward direction through the separating mechanism 30 to change the material trajectory for sorting. For example, the separating mechanism 30 jets high-pressure gas vertically downward. After receiving the signal from the control module, the blowing component of the separating mechanism 30 can jet high-pressure gas in the vertically downward direction, so that the material changes from the trajectory c to move along the trajectory d, and finally the material will fall into the first recovery area 41. The unaffected materials continue to fall along the parabolic trajectory c and reach the second recovery area 42 to achieve sorting. In the present disclosure, applying a force downward, such as blowing downward, is easier to control the direction, and the accuracy can be improved by combining with gravity.

[0054] In some embodiments, as Figure 2 shown, the separating mechanism 30 may include: a first downward separating mechanism 33 for applying a force to the materials 200a of the first category to change the trajectory d of the materials 200a of the first category so as to fall into the first recovery area 41, where the first recovery area 41 is one of the multiple recovery areas. In the embodiments of the present disclosure, the first downward separating mechanism 33 can be arranged above the initial oblique upward throwing motion trajectory c of the material 200, and a downward force (which can be a force directly below the gravity direction x or an oblique downward force) is applied to the materials 200a of the first type through the first downward separating mechanism 33 so that the materials 200a of the first type fall into the first recovery area 41 along the trajectory d. On the other hand, the first downward separating mechanism 33 may not apply a force to the materials 200b of the second type different from the first type, so that the materials 200b of the second type continue to fall along the trajectory c into the second recovery area 42. This embodiment can save costs and accurately sort.

[0055] In some embodiments, the separating mechanism 30 may further include: a second downward separating mechanism (not shown in the figure), disposed on one side of the first downward separating mechanism 33, which may be located downstream of the movement trajectory c of the material 200, and is configured to apply a force to the material 200b of the second category to change the trajectory of the material 200b of the second category so as to fall into the second recovery area 42, wherein the second category is a material category different from the first category, and the second recovery area 42 is one of the multiple recovery areas and is different from the first recovery area 41. In the embodiments of the present disclosure, another second downward separating mechanism for applying a force from above may be correspondingly provided for the second recovery area 42, and the second downward separating mechanism applies a force to the material 200b of the second category so that the material 200b of the second category falls into the second recovery area 42. Through the two separating mechanisms applying downward forces, sorting can be accurately performed. Moreover, a third recovery area (not shown in the figure) may be provided, and for the materials of the third category, they fall along the initial trajectory into the third recovery area that is farther from the conveying mechanism 10 than the second recovery area 42, thereby realizing the sorting of more types of materials.
