Technical Field

[0001] This invention relates to the field of logistics sorting, and more particularly to a sorting device and sorting system. Background Technology

[0002] In the field of logistics sorting and distribution, parcel sorting currently relies solely on manual stacking of loose items. However, with rising labor costs, higher demands are being placed on the efficiency and accuracy of the loading platform.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0065] like Figure 1 and Figure 2 As shown, some embodiments of the present invention provide a sorting device, mainly used for sorting bulk materials. The sorting device includes a base 100, a hopper 200, a power unit 300, a rotating shaft 400, and a transmission mechanism 500.

[0066] The base 100 has two limiting plates 600 on each side, which are parallel to each other and are vertically installed on both sides of the base 100. It should be noted that in some embodiments of the present invention, the limiting plates are not limited to blocks or limiting frames, etc., and can be specifically defined according to the actual situation.

[0067] Meanwhile, the two ends of the rotating shaft 400 are rotatably positioned between the two limiting plates 600 via bearings. It can be understood that the rotating shaft 400 can rotate between the two limiting plates 600.

[0068] Specifically, two bearing seats are provided on the base 100 to support the rotating shaft 400, so as to ensure the smoothness and stability of the rotating shaft 400 during rotation.

[0069] In addition, the rotating shaft 400 is connected to the power device 300 for transmission, and the power device 300 is connected to the base 100. It should be noted that in some embodiments of the present invention, the power device 300 can be any one of a stepper motor, a DC motor, or an AC motor, and can be specifically set according to the actual situation.

[0070] Specifically, the output end of the power unit 300 is connected to the rotating shaft 400 via a conveyor belt. When the power unit 300 is powered on, the output end of the power unit 300 drives the conveyor belt to rotate, which in turn drives the rotating shaft 400 to rotate. The rotation frequency of the rotating shaft 400 can be adjusted by adjusting the rotation frequency of the power unit 300, and the rotation direction of the rotating shaft 400 can also be adjusted by adjusting the rotation direction of the power unit 300.

[0071] Optionally, in other embodiments of the present invention, the output end of the power unit 300 may also be connected to the rotating shaft 400 via gears. Specifically, a transmission gear is fitted onto the output end of the power unit 300, and the axis of the transmission gear coincides with the axis of the output end of the power unit 300. Simultaneously, a driven gear is fitted onto the rotating shaft 400, and the driven gear is fixedly connected to the rotating shaft 400, with its axis coinciding with the axis of the rotating shaft 400. The driven gear and the transmission gear are externally meshed. When the output end of the power unit 300 drives the transmission gear to rotate, the transmission gear drives the driven gear to rotate. The rotational speed of the driven gear can be controlled by adjusting the rotational speed of the transmission gear, and the rotational direction of the driven gear can also be controlled by adjusting the rotational direction of the transmission gear.

[0072] The hopper 200 is hinged to two sides with a first side door 220 and a second side door 230. It is understood that the first side door 220 and the second side door 230 can rotate along the edges of the hopper 200. The hopper 200 is also connected to the rotating shaft 400.

[0073] It should be noted that the hopper 200 also includes two parallel side plates 240. The two side plates 240, the first side door 220, and the second side door 230 form the four sides of the hopper. The two side plates 240, the first side door 220, and the second side door 230 are respectively connected to the bottom plate 210 of the hopper to form the hopper 200. The hopper 200 has a receiving groove inside. In one embodiment, the bottom plate 210 is V-shaped.

[0074] Meanwhile, the lower ends of the two side plates 240 extend downwards below the receiving groove, and the two ends of the rotating shaft 400 are mounted on the surfaces of the two side plates 240 located below the receiving groove via bearings. It can be understood that when the rotating shaft 400 rotates, the hopper 200, which is fixedly connected to the rotating shaft 400, rotates along with the rotating shaft 400.

[0075] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, the axis of the rotating shaft 400 is perpendicular to the side plate 240, and the axis of the rotating shaft 400 is parallel to the first side door 220 and the second side door 230. It can be understood that when the rotating shaft 400 rotates, the hopper 200 rotates toward the first side door 220 or the second side door 230 to sort the material in the hopper 200.

[0076] It should be noted that there are two side panels 240, and at least one side panel 240 is provided with a transmission mechanism 500. That is, any one side panel 240 is provided with a transmission mechanism 500, or both side panels 240 are provided with transmission mechanisms 500 respectively, which can be specifically set according to the actual situation. In some embodiments of the present invention, the two side panels 240 are provided with transmission mechanisms 500 respectively to improve the stability of opening or closing the first side door 220 and the second side door 230.

[0077] The transmission mechanism 500 is rotatably mounted on the side plate 240 of the hopper 200. Specifically, the transmission mechanism 500 is rotatably mounted on the side of the side plate 240 near the limiting plate 600. The transmission mechanism 500 includes a first transmission component 510 and a second transmission component 520, and the first transmission component 510 and the second transmission component 520 are respectively rotatably connected to the side plate 240 of the hopper 200.

[0078] Specifically, the first transmission assembly 510 and the second transmission assembly 520 are spaced apart on the side plate 240 of the hopper 200. The first transmission assembly 510 and the second transmission assembly 520 are symmetrically arranged on both sides of the rotating shaft 400. The first transmission assembly 510 is drive-connected to the first side door 220, and the second transmission assembly 520 is drive-connected to the second side door 230. In some embodiments of the present invention, to prevent materials from falling from the first side door 220 or the second side door 230 under their own weight, when the hopper 200 rotates a first angle toward the first side door 220 or the second side door 230, both the first side door 220 and the second side door 230 are closed. At this time, the materials placed in the hopper 200 remain stable, preventing materials from falling from the hopper 200 before it reaches the designated position, thus improving the sorting quality and stability of the materials.

[0079] Furthermore, when the hopper 200 rotates a second angle after rotating a first angle toward the side where the first side door 220 is located, the first transmission assembly 510 drives the first side door 220 to open. Specifically, when the rotation direction of the hopper 200 is toward the first side door 220, and the rotation angle of the hopper 200 gradually reaches the second angle, the first side door 220 gradually opens under the drive of the first transmission assembly 510, while the second side door 230 remains closed at all times.

[0080] Similarly, when the hopper 200 rotates a first angle towards the side where the second side door 230 is located, and then rotates a second angle, the second side door 230 is opened by the second transmission assembly 520. Specifically, when the rotation direction of the hopper 200 is towards the second side door 230, and the rotation angle of the hopper 200 gradually reaches the second angle, the second side door 230 gradually opens under the drive of the second transmission assembly 520, while the first side door 220 remains closed.

[0081] In order to improve the stability of the opening or closing of the first side door 220 and the second side door 230 during the rotation of the hopper 200, a limiting channel 610 is provided on the side of the limiting plate 600 near the hopper 200.

[0082] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the limiting plate 600 has limiting channels 610 on its surface. The limiting channels 610 include a first arc-shaped hole 611, a second arc-shaped hole 612, and a third arc-shaped hole 613 that are connected in sequence. Specifically, the limiting channels 610 are symmetrically distributed with respect to the vertical plane containing the axis of the rotating shaft 400.

[0083] Specifically, in some embodiments of the present invention, the limiting channel 610 is a curved channel, such as a "W" shaped channel.

[0084] It should be noted that the axis of the second arc-shaped hole 612 coincides with the axis of the rotating shaft 400, and the first arc-shaped hole 611 extends toward the location of the first side door 220, while the third arc-shaped hole 613 extends toward the location of the second side door 230.

[0085] When the hopper 200 is in a horizontal state, the first roller 514 and the second roller 524 are respectively located in the second arc-shaped hole 612 at intervals.

[0086] When the hopper 200 rotates from the horizontal position towards the side where the first side door 220 is located by a first angle, the hopper 200 drives the first roller 514 and the second roller 524 to move together along the second arc-shaped hole 612 of the limiting channel 610 until the first roller 514 is at the connection between the first arc-shaped hole 611 and the second arc-shaped hole 612; during this process, the first side door 220 and the second side door 230 remain closed. Similarly, when the hopper 200 rotates from the horizontal position towards the side where the second side door 230 is located by a first angle, the hopper 200 drives the first roller 514 and the second roller 524 to move together along the second arc-shaped hole 612 of the limiting channel 610 until the second roller 524 is at the connection between the second arc-shaped hole 612 and the third arc-shaped hole 613; during this process, the first side door 220 and the second side door 230 also remain closed.

[0087] When the hopper 200 rotates to the first angle and continues to rotate, the first side door 220 or the second side door 230 begins to slowly open. When the hopper 200 rotates to the second angle, the first roller 514 slides to the end of the first arc-shaped hole 611 away from the third arc-shaped hole 613, while the second roller 524 remains within the second arc-shaped hole 612. Alternatively, the second roller 524 slides to the end of the second arc-shaped hole 612 away from the first arc-shaped hole 611, while the first roller 514 remains within the second arc-shaped hole 612. This can be specifically set according to actual conditions, and the material in the hopper 200 can be unloaded from the first side door 220 or the second side door 230 respectively to improve the sorting efficiency of bulk materials.

[0088] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the first transmission assembly 510 includes a first connecting rod 511, a first swing rod 512, a first connecting member 513, and a second connecting member 515.

[0089] Specifically, one end of the first connecting rod 511 is rotatably connected to one end of the first swing rod 512 through the second connecting member 515, and the other end of the first connecting rod 511 is rotatably connected to the first side door 220 through the first connecting member 513.

[0090] The first rocker arm 512 is provided with a first roller 514 at the other end. The first roller 514 is slidably connected to the limiting channel 610, that is, the first roller 514 can move along the inner wall of the limiting channel 610. The first rocker arm 512 is rotatably connected to the side plate 240 of the hopper 200, that is, the first rocker arm 512 can rotate along the side plate 240 of the hopper 200.

[0091] In some embodiments of the present invention, the first swing arm 512 is a bent arm (such as a "V" shaped arm or a "U" shaped arm, etc.). When the first swing arm 512 is a V-shaped bent arm, the bent part of the first swing arm 512 is rotatably mounted on the outside of the side plate 240 by means of a pin, so that the first swing arm 512 rotates along the axis of the pin.

[0092] It should be noted that when the rotation angle of the hopper 200 toward the first side door 220 changes from the first angle to the second angle, the first swing rod 512 drives the first connecting rod 511 to swing toward the direction closer to the rotating shaft 400 during the swinging process. During the swinging process, the first connecting rod 511 pulls the first side door 220 open through the first connecting piece 513.

[0093] like Figures 2 to 5 As shown, in some embodiments of the present invention, the second transmission assembly 520 includes a second connecting rod 521, a second swing rod 522, a third connecting member 523, and a fourth connecting member 525.

[0094] Specifically, one end of the second connecting rod 521 is rotatably connected to one end of the second swing rod 522 via the fourth connecting member 525, and the other end of the second connecting rod 521 is rotatably connected to the second side door 230 via the third connecting member 523. The first connecting member 513, the second connecting member 515, the third connecting member 523, and the fourth connecting member 525 can be pins or other rotating connecting members. A second roller 524 is provided at the other end of the second swing rod 522, the second roller 524 is slidably connected to the limiting hole 610, and the second swing rod 522 is rotatably connected to the side plate 240 of the hopper 200.

[0095] In some embodiments of the present invention, the second swing arm 522 is also a bent arm (such as a "V" shaped arm or a "U" shaped arm, etc.). When the first swing arm 512 is a V-shaped bent arm, the bent part of the second swing arm 522 is rotatably mounted on the outside of the side plate by a pin, so that the second swing arm 522 rotates along the axis of the pin.

[0096] It should be noted that when the hopper 200 rotates towards the second side door 230, the second roller 524 moves within the limiting channel 610 as the hopper 200 rotates. When the rotation angle of the hopper 200 is the first angle, the second transmission assembly 520 and the side plate 240 of the hopper 200 are relatively stationary, and the second side door 230 remains closed. At the same time, the end of the first transmission assembly 510 connected to the limiting channel 610 slides along the limiting channel 610, and the first transmission assembly 510 and the side plate 240 of the hopper 200 are relatively stationary, and the first side door 220 remains closed.

[0097] Specifically, as the rotation angle of the hopper 200 toward the second side door 230 changes from the first angle to the second angle, the second swing rod 522 drives the second connecting rod 521 to swing toward the direction closer to the rotating shaft 400 during the swinging process. During the swinging process, the second connecting rod 521 pulls the second side door 230 open through the third connecting piece 523.

[0098] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, a first limiting block 700 and a second limiting block 800 are arranged at intervals on both sides of the side plate 240 of each hopper 200. The first limiting block 700 and the second limiting block 800 are mounted on the base 100. The vertical distances of the first limiting block 700 and the second limiting block 800 to the axis of the rotating shaft 400 are equal, and the first limiting block 700 and the second limiting block 800 are symmetrical about the plane formed by the vertical line from a point on the axis of the rotating shaft 400 to the base 100 and the axis of the rotating shaft 400.

[0099] The first limiting block 700 is used to limit the side of the side plate 240 near the first side door 220. When the hopper 200 rotates normally, the first limiting block 700 does not contact the side plate 240. When the device is damaged and the hopper 200 tilts towards the first side door 220, the side plate 240 abuts against the first limiting block 700 to prevent the hopper 200 from continuing to tilt towards the first side door 220 and damaging itself or other parts.

[0100] Additionally, the second limiting block 800 is used to limit the movement of the side plate 240 near the second side door 230. When the hopper 200 rotates normally, the second limiting block 800 does not contact the side plate 240. When the device malfunctions and causes the hopper 200 to tip toward the second side door 230, the side plate 240 abuts against the second limiting block 800 to prevent the hopper 200 from continuing to tip toward the second side door 230 and damaging itself or other components.

[0101] It should be noted that when the hopper 200 rotates towards the second side door 230 at the second angle, and during the reset process, the first roller 514 moves along the first arc-shaped hole 611 towards the direction closer to the second arc-shaped hole 612, and at the same time drives the first connecting rod 511 to swing away from the rotating shaft 400. The first connecting rod 511 drives the first side door 220 to close through the first connecting piece 513.

[0102] When the hopper 200 rotates towards the first side door 220 at the second angle, and during the reset process, the second roller 524 moves along the third arc-shaped hole 613 towards the direction closer to the second arc-shaped hole 612, while simultaneously driving the second connecting rod 521 to swing away from the rotating shaft 400. The second connecting rod 521 also drives the third connecting member 523 and the connection part of the second connecting rod 521 to swing away from the rotating shaft 400, and the third connecting member 523 drives the second side door 230 to close.

[0103] like Figure 3 As shown, in some embodiments of the present invention, the first connector 513 is rotatably connected to the first side door 220, so that the first connector 513 drives the first side door 220 to rotate during the rotation process.

[0104] Meanwhile, the third connector 523 is rotatably connected to the second side door 230, so that the third connector 523 drives the second side door 230 to rotate during the rotation process.

[0105] Optionally, the first link 511 and the second link 521 can be either a telescopic rod or a joint bearing link, which can be specifically set according to the actual situation, and assembly errors can be compensated by adjusting the length of the first link 511 and the second link 521.

[0106] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the side plate 240 is provided with a first limiting member 900 and a second limiting member 1000 spaced apart on both sides.

[0107] Specifically, the first limiting member 900 and the second limiting member 1000 are respectively installed on the side plate 240 of the hopper 200, and the first limiting member 900 forms a limit with the first swing rod 512, and the second limiting member 1000 forms a limit with the second swing rod 522, so as to avoid the first swing rod 512 and the second swing rod 522 swinging excessively, thereby improving the reliability of the first swing rod 512 and the second swing rod 522 in the swing end.

[0108] The first limiting member 900 and the second limiting member 1000 can be either a limiting block or a limiting post. In some embodiments of the present invention, the first limiting member 900 and the second limiting member 1000 are nylon limiting posts.

[0109] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, fixing plates 1100 are respectively sleeved at both ends of the rotating shaft 400, and the fixing plates 1100 are detachably installed on the outside of the side plate 240. The fixing plates 1100 can be connected to the side plate by any one of bolt connection, adhesive bonding, or snap-fit ​​connection.

[0110] In some embodiments of the present invention, in order to improve the stability of the fixing plate 1100 on the side plate 240, the fixing plate 1100 is installed on the side plate 240 by bolts, thereby improving the loading and unloading efficiency of the fixing plate on the side plate.

[0111] The two side plates 240 of the hopper 200 are respectively connected to the rotating shaft 400 through the fixing plate 1100. At the same time, a signal triggering device 1700 is provided on the fixing plate 1100, and the signal triggering device 1700 is also installed on the side of the fixing plate 1100 away from the side plate 240 by bolts.

[0112] Meanwhile, a signal detection device 1200 is provided on the limiting plate 600. The signal detection device 1200 is used to cooperate with the signal triggering device 1700. When the hopper 200 is in a horizontal position, the signal detection device 1200 faces the signal triggering device 1700 and triggers the signal detection device 1200 to send a control signal to the background processor.

[0113] In some embodiments of the present invention, the signal detection device 1200 detects whether the hopper 200 has been reset.

[0114] Specifically, when the hopper 200 is connected to a power source and the signal triggering device 1700 is directly opposite the signal detection device 1200, the signal detection device 1200 detects a signal, and the hopper 200 is in a horizontal position. When the signal triggering device 1700 and the signal detection device 1200 are misaligned, the signal detection device 1200 detects no signal, and the hopper 200 is in a tilted position. The power device 300 can drive the rotating shaft 400 to rotate, thus adjusting the hopper 200 to a horizontal position.

[0115] In one embodiment, the signal detection device 1200 is a proximity switch and the signal triggering device 1700 is a sensor plate.

[0116] It should be noted that a proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch to the operating distance, the switch can be activated without mechanical contact or the application of any pressure, thereby driving DC electrical appliances or providing control commands to computer (PLC) devices. A proximity switch is a type of switch sensor (i.e., a contactless switch). It possesses the characteristics of limit switches and microswitches, while also having sensing capabilities. It is reliable, stable, has a fast frequency response, long service life, strong anti-interference ability, and is waterproof, shockproof, and corrosion-resistant. Products are available in inductive, capacitive, Hall effect, AC, and DC types.

[0117] like Figures 1 to 4As shown, in some embodiments of the present invention, a first spring 1800 is provided between the side plate 240 and the first transmission assembly 510. The first spring 1800 is disposed above the first transmission assembly 510, and one end of the first spring 1800 is connected to the side plate 240, while the other end of the first spring 1800 is connected to one end of the first swing rod 512. The first spring 1800 drives the first transmission assembly 510 to reset, and simultaneously drives the first side door 220 to reset, i.e., the first side door 220 closes. Simultaneously, a second spring 1900 is provided between the side plate 240 and the second transmission assembly 520. The second spring 1900 is disposed above the second transmission assembly 520, and one end of the second spring 1900 is connected to the side plate 240, while the other end of the second spring 1900 is connected to one end of the second swing rod 522. The second spring 1900 drives the second transmission assembly 520 to reset, and simultaneously drives the second side door 230 to reset, i.e., the second side door 230 closes.

[0118] It should be noted that when the hopper 200 is in a horizontal position, both the first spring 1800 and the second spring 1900 are in their original lengths. When the hopper 200 rotates from the horizontal position toward the first side door 220, and the rotation angle is the first angle, the first side door 220 and the second side door 230 remain closed. At the same time, the first transmission assembly 510 and the second transmission assembly 520 remain stationary relative to the side plate 240, and the first spring 1800 and the second spring 1900 remain in their original lengths.

[0119] As the hopper 200 continues to rotate toward the first side door 220, and the rotation angle gradually changes from the first angle to the second angle, the first transmission assembly 510 gradually moves toward the direction closer to the rotating shaft 400, and drives the first swing arm 512 to move toward the direction closer to the rotating shaft 400. At this time, the first spring 1800 is in a stretched state and stores elastic potential energy, while the first side door 220 opens. Meanwhile, the second side door 230 remains closed, the second transmission assembly 520 is stationary relative to the side plate 240, and the second spring 1900 remains at its original length.

[0120] As the hopper 200 gradually returns to a horizontal state, and as it rotates a second angle toward the second side door 230, the first spring 1800 gradually returns to its original length, causing the first rocker arm 512 to return to its initial position. The rocker arm 512 then drives the first connecting rod 511 and the first connecting member 513 to return to their initial positions, and simultaneously, the first connecting member 513 causes the first side door 220 to close. At this time, the second spring 1900 remains at its original length. When the hopper 200 rotates a first angle toward the second side door 230, it returns to a horizontal state.

[0121] In addition, when the hopper 200 rotates from the horizontal position toward the second side door 230 and the rotation angle is the first angle, the first side door 220 and the second side door 230 remain closed. At the same time, the first transmission assembly 510 and the second transmission assembly 520 remain stationary relative to the side plate 240, and the first spring 1800 and the second spring 1900 remain in their original length.

[0122] As the hopper 200 continues to rotate toward the second side door 230, and the rotation angle gradually changes from the first angle to the second angle, the second transmission assembly 520 gradually moves toward the direction closer to the rotating shaft 400, and drives the second swing arm 522 to move toward the direction closer to the rotating shaft 400. At this time, the second spring 1900 is in a stretched state and stores elastic potential energy, while the second side door 230 opens. Meanwhile, the first side door 220 remains closed, the first transmission assembly 510 is stationary relative to the side plate, and the first spring 1800 remains at its original length.

[0123] As the hopper 200 gradually returns to a horizontal state, when it gradually rotates towards the first side door 220 to a second angle, the second spring 1900 gradually returns to its original length, driving the second swing rod 522 to return to its initial position. The second swing rod 522 then drives the second connecting rod 521 and the third connecting member 523 to return to their initial positions, and simultaneously, the third connecting member 523 drives the second side door 230 to close. At this time, the first spring 1800 remains at its original length. When the hopper 200 rotates towards the first side door 220 to a first angle, the hopper 200 returns to a horizontal state.

[0124] like Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments of the present invention, a first support member 2000 and a second support member 2100 spaced apart are provided on both sides of the base 100, and the first support member 2000 and the second support member 2100 are symmetrically arranged on both sides of the rotating shaft 400. Meanwhile, a third roller 2200 is provided on the first support member 2000, and a fourth roller 2300 is provided on the second support member 2100. The third roller 2200 and the fourth roller 2300 are symmetrically arranged on both sides of the rotating shaft 400, and the axes of the third roller 2200 and the fourth roller 2300 are both parallel to the axis of the rotating shaft 400.

[0125] Additionally, a first support arm 1300 and a second support arm 1400 are provided at intervals on the inner side of the side plate 240. The side of the first support arm 1300 away from the rotating shaft 400 contacts the third roller 2200, so that during the rotation of the hopper 200 toward the first side door 220, the first support arm 1300 slides on the third roller 2200, and the third roller 2200 provides support for the hopper 200, improving the stability of the hopper 200 during rotation toward the first side door 220. Simultaneously, the side of the second support arm 1400 away from the rotating shaft 400 contacts the fourth roller 2300, so that during the rotation of the hopper 200 toward the second side door 230, the second support arm 1400 slides on the fourth roller 2300, and the fourth roller 2300 provides support for the hopper 200, improving the stability of the hopper during rotation toward the second side door 230.

[0126] The first support arm 1300 is provided with a first limiting baffle 1310. At the same time, the second support arm 1400 is provided with a second limiting baffle 1410.

[0127] When the hopper 200 rotates to the second angle, the first limiting baffle 1310 abuts against the third roller 2200 to form a limit, or the second limiting baffle 1410 abuts against the fourth roller 2300 to form a limit.

[0128] Understandably, when the hopper 200 rotates to the second angle towards the first side door 220, the first limiting baffle 1310 abuts against the third roller 2200 to form a limit, thereby improving the stability of the hopper 200. When the hopper 200 rotates to the second angle towards the second side door 230, the second limiting baffle 1410 abuts against the fourth roller 2300 to form a limit, thereby improving the stability of the hopper.

[0129] It should be noted that the first support arm 1300 and the second support arm 1400 are both arc-shaped arms, and the axes corresponding to the first support arm 1300 and the second support arm 1400 are respectively coincident with the axis of the rotating shaft 400. It can be understood that when the hopper rotates, the first support arm 1300 and the second support arm 1400 rotate about the axis of the rotating shaft. During the rotation of the hopper 200, the third roller 2200 rolls along the outer arc surface of the first support arm 1300, or the fourth roller 2300 rolls along the outer arc surface of the second support arm 1400. Figure 3 , Figure 5 and Figure 7 As shown, in some embodiments of the present invention, the first limiting baffle 1310 is provided with a first buffer screw 1500, and the second limiting baffle 1410 is provided with a second buffer screw 1600.

[0130] The first buffer screw 1500 and the second buffer screw 1600 are both made of nylon. When the hopper rotates to its maximum angle, the first buffer screw 1500 abuts against the third roller 2200, or the second buffer screw 1600 abuts against the fourth roller 2300, to provide a buffering effect.

[0131] Specifically, the position of the first buffer screw 1500 on the first limiting baffle 1310 can be rotated to adjust the distance between the end of the first buffer screw 1500 near the third roller 2200 and the axis of the third roller 2200, thus compensating for assembly errors and ensuring that the first buffer screw 1500 can abut against the third roller 2200 when the hopper 200 rotates to its maximum angle. Simultaneously, the position of the second buffer screw 1600 on the second limiting baffle 1410 can be rotated to adjust the distance between the end of the second buffer screw 1600 near the fourth roller 2300 and the axis of the fourth roller 2300, thus compensating for assembly errors and ensuring that the second buffer screw 1600 can abut against the fourth roller 2300 when the hopper 200 rotates to its maximum angle.

[0132] For example Figure 2 and Figure 9 As shown, in some embodiments of the present invention, a first limiting support plate 2500 is provided on the lower surface of the bottom plate 210 of the hopper 200 near the edge of the first side door 220. The first limiting support plate 2500 is stacked on the bottom plate 210 and extends out of the hopper 200 towards the side door 220 to limit the movement of the hopper 200. When the first side door 220 is fully opened, the first side door 220 is supported on the first limiting support plate 2500 to prevent the rotation angle of the first side door 220 from exceeding 90°. Meanwhile, on the bottom plate... A second limiting support plate 2600 is provided on one edge of the lower surface of 210 near the second side door 230. The second limiting support plate 2600 is stacked on the bottom plate 210 and extends to the outside of the hopper 200 on the side facing the second side door 230 to form a limit with the second side door 230. When the second side door 230 is fully opened, the second side door 230 is supported on the second limiting support plate 2600 to prevent the turning angle of the second side door 230 from being greater than 90°, thereby improving the smoothness and stability of the first side door 220 and the second side door 230 when opening or closing.

[0133] For example Figure 8 and Figure 9As shown, some embodiments of the present invention also provide a sorting system, which includes a guide rail 2400 and a sorting device 10 as described in any of the above embodiments. There are multiple sorting devices 10, and each sorting device 10 is slidably disposed on the guide rail 2400.

[0134] Multiple sorting devices 10 can be arranged at intervals on the guide rail 2400.

[0135] Optionally, multiple sorting devices 10 can also be interconnected on the guide rail 2400 via connectors.

[0136] It should be noted that the number of sorting devices 10 can be any number of one, two, or more, and can be set according to the actual situation.

[0137] The shape of the guide rail 2400 can be any one of the following: straight line, polygonal line, curved line, circle, ellipse or polygon.

[0138] In addition, the plane in which the hopper 200 swings is perpendicular to the direction of travel of the sorting device 10, so that the material in the hopper 200 can be sorted on both sides of the guide rail 2400 during the movement of the hopper 200 on the guide rail 2400.

[0139] Understandably, sorting efficiency can be improved by increasing the number of sorting devices 10 on the guide rail 2400.

[0140] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0141] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0142] The embodiments described above are merely examples 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 present 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.
