Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0056] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0057] The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0058] The present invention provides a picking platform assembly for potato sorting equipment, comprising a mounting frame 1, a picking chain platform 2, a primary screening and feeding device 3, and a blanking conveying mechanism 4;

[0059] The picking chain platform 2 includes a receiving arm 21 and a filter chain platform 22. The receiving arm 21 is rotatably mounted on the mounting frame 1. The end of the receiving arm 21 facing the filter chain platform 22 is rotatably adjusted horizontally and vertically. The end of the filter chain platform 22 away from the receiving arm 21 is rotatably mounted on the mounting frame 1. The filter chain platform 22 is tilted. The end of the filter chain platform 22 facing the receiving arm 21 is vertically adjusted in the horizontal direction. The receiving arm 21 and the filter chain platform 22 correspond to each other.

[0060] The primary screening feeding device 3 includes a primary screening mechanism 31, which includes a gap adjustment component 311 and a plurality of mounting rods 312. The outer wall of the mounting rod 312 is sleeved with a coil spring 313. The mounting rod 312 and the gap adjustment component 311 are movably matched to adjust the gap distance between two adjacent mounting rods 312.

[0061] The blanking conveying mechanism 4 includes an input conveyor belt 41, a detector 42, and a rejection component 43. The detector 42 is provided with a detection channel 421 corresponding to the input conveyor belt 41. The rejection component 43 is located in the detection channel 421, and the rejection component 43 is connected to the detector 42 by signal.

[0062] By adopting the above technical solution, the receiving arm 21 transfers the received potatoes to the filter chain table 22, and the filter chain table 22 filters impurities such as soil and leaves, which is convenient for the later classification of potatoes. The receiving arm 21 and the filter chain table 22 can be rotated and adjusted, which can make the working cooperation between the receiving arm 21 and the filter chain table 22 more coordinated and more adaptable, and can effectively reduce potato leakage; the potatoes are transported to the primary screening mechanism 31 along the filter chain table 22, and the potatoes are rubbed on the surface during rolling on the coil spring 313, so that impurities on the potato surface are cleaned, and soil and smaller potatoes fall through the gap between the two adjacent mounting rods 312, so that the device can remove impurities. The accuracy is higher and the grading accuracy is higher. In addition, the gap adjustment component 311 can adjust the gap width between two adjacent mounting rods 312, so that the primary screening mechanism 31 can flexibly adjust the grade of the screened potatoes, making the device more applicable and more practical. The potatoes screened by the primary screening mechanism 31 enter the input conveyor belt 41, and then pass through the detection channel 421 along a parabola. After detection by the detector 42, qualified products fall without hindrance. When the detector 42 detects unqualified products, it sends a rejection signal to the rejection component 43, and the rejection component 43 is started to change the landing trajectory of the unqualified products, which can realize accurate sorting of potatoes during blanking and transmission, save manpower and material resources, and is more convenient to use.

[0063] In this embodiment, a first telescopic driving member 221 is provided on the mounting frame 1, and the driving end of the first telescopic driving member 221 is linked to the filter chain stage 22. A rotating connection member is provided at the end of the filter chain stage 22 away from the receiving arm 21. The filter chain stage 22 rotates with the mounting frame 1 through the rotating connection member, and the rotating connection member is linked to the first telescopic driving member 221 so that the filter chain stage 22 rotates in a vertical direction with the rotating connection member as the center, thereby realizing height adjustment of the filter chain stage 22 toward the receiving end. The two ends of the first telescopic driving member 221 are respectively hingedly connected to the filter chain stage 22 and the mounting frame 1, and the first telescopic driving member 221 is tilted. It should be noted that the rotation angle range of the filter chain stage 22 is 0°-30°, and the tilt angle of the first telescopic driving member 221 is 45°-75°, which can enable the filter chain stage 22 to better cooperate with the receiving arm 21.

[0064] In this embodiment, the mounting frame 1 includes a fixed portion 11, a rotating connection portion 12, and a stabilizing portion 13. The two ends of the rotating connection portion 12 are hingedly connected to the fixed portion 11 and the stabilizing portion 13 respectively. The rotating portion 4322 is engaged with the fixed portion 11, and the rotating connection portion 12 is configured as a triangular prism structure so that both ends of the rotating portion 4322 can be rotated and adjusted along the horizontal transverse direction, thereby realizing the horizontal transverse rotation adjustment of the receiving arm 21. It should be noted that the rotating portion 4322 can be rotated and adjusted in the angle range of 0°-60°, and it is manually rotated and adjusted during use.

[0065] In this embodiment, a fixed beam 211 is provided on the receiving arm 21, and a second telescopic driving member 212 is arranged in contact between the fixed beam 211 and the stabilizing portion 13, and the two ends of the second telescopic driving member 212 are hingedly connected to the fixed beam 211 and the stabilizing portion 13 respectively. The end of the receiving arm 21 facing the filter chain table 22 is rotatably connected to the stabilizing portion 13, so that the receiving arm 21 rotates in the vertical direction with the connection between it and the stabilizing portion 13 as the center. It should be noted that the angle range of the receiving arm 21 in the vertical direction is 0°-90°, which can enable the potatoes received by the receiving arm 21 to be more accurately put into the filter chain table 22. Furthermore, the working cooperation between the receiving arm 21 and the filter chain table 22 can be more coordinated, the adaptability is higher, and the leakage of potatoes can be effectively reduced.

[0066] In this embodiment, the receiving arms 21 include two groups. When one group of receiving arms 2 receives potatoes from the unloading truck, the other group of receiving arms 2 can adjust its position and angle in advance to prepare for receiving potatoes. In addition, by adjusting the angles and positions of the two groups of receiving arms 2, the two groups of receiving arms 2 can simultaneously receive potatoes unloaded from the unloading truck, making the picking chain platform more efficient and more flexible to use.

[0067] In this embodiment, the filter chain table 22 includes a circulating feeding belt 222, a rotating roller 223, a transmission gear 224, and a supporting member 225. The rotating roller 223 is linked to a motor for driving the transmission roller 324 to rotate. The transmission gear 224 is sleeved and fixed on the outer wall of the rotating roller 223. The rotating roller 223 rotates synchronously with the transmission gear 224. In this embodiment, the rotating roller 223 includes three groups, which are respectively located at both ends and the middle of the circulating feeding belt 222. The transmission gear 224 is installed on the rotating roller 223 located in the middle.

In other embodiments, the linkage between the rotating roller 223 and the motor can be set to a transmission belt 4362 transmission, a transmission chain transmission, or other transmission methods. It should be noted that the transmission gear 224 is meshed with the lower rotating part of the circulating feeding belt 222, which can effectively avoid affecting the transportation of potatoes on the upper transport part of the circulating feeding belt 222.

[0068] In this embodiment, the circulating feeding belt 222 includes a mounting belt 2221 and a carrying roller 2222. The mounting belt 2221 includes two groups, and the two ends of the carrying roller 2222 are fixedly connected to the two groups of mounting belts 2221. In this embodiment, the mounting belt 2221 includes three groups distributed side by side, and a carrying roller 2222 is installed between two adjacent mounting belts 2221, so that the width of the filter chain table 22 in this embodiment is wider and more potatoes can be transported. It should be noted that a gap is provided between two adjacent carrying rollers 2222, which can filter impurities such as soil and leaves, and facilitate the later grading of potatoes.

[0069] In this embodiment, the carrying roller 2222 includes a first transmission roller 22221 and a second transmission roller 22222. In the direction of transporting materials along the circulating feeding belt 222, the height of the top end surface of the second transmission roller 22222 is greater than the height of the top end surface of the first transmission roller 22221. Four first transmission rollers 22221 are arranged between two adjacent second transmission rollers 22222, which can effectively prevent the potatoes from rolling and colliding, and thus effectively prevent the potatoes from breaking the skin. In other embodiments, the distribution number and distribution method of the first transmission roller 22221 and the second transmission roller 22222 can be adjusted according to actual work needs, and rubber sleeves are provided on the first transmission roller 22221 and the second transmission roller 22222, which can effectively prevent the potatoes from breaking the skin.

[0070] In this embodiment, the supporting members 225 include two groups, namely, an upper supporting member 2251 and a lower supporting member 2252. There are multiple upper supporting members 2251 and multiple lower supporting members 2252 respectively. Based on the horizontal direction, the height of the upper supporting member 2251 is greater than the height of the lower supporting member 2252. The lower end surface of the circulating feeding belt 222 is respectively abutted against the upper end surface of the upper supporting member 2251 and the upper end surface of the lower supporting member 2252. The upper supporting member 2251 is used to support the upper transport part of the circulating feeding belt 222, and the lower supporting member 2252 is used to support the lower rotating part of the circulating feeding belt 222, which can make the circulating rotation of the circulating feeding belt 222 on the filter chain table 22 more stable.

[0071] In this embodiment, the mounting rod 312 is synchronously linked with the gap adjustment component 311, and the gap adjustment component 311 includes a plurality of first linkage plates 3111 and a plurality of second linkage plates 3112 that are synchronously linked. An adjusting member 3113 is provided on the first linkage plate 3111, and both ends of the second linkage plate 3112 are respectively hingedly connected to the two first linkage plates 3111. A rotating member 226 is provided on the first linkage plate 3111, and the rotating member 226 passes through the first linkage plate 3111 and the second linkage plate 3112, and the mounting rod 312 rotates with the rotating member 226. It should be noted that the plurality of first linkage plates 3111 are connected. They are parallel to each other, and multiple second linkage plates 3112 are parallel to each other. The inclination angles of the first linkage plate 3111 and the second linkage plate 3112 are opposite to each other. By adjusting the inclination angles of the first linkage plate 3111 and the second linkage plate 3112, the gap width between two adjacent mounting rods 312 can be adjusted. In this embodiment, the rotating member 226 is configured as a bearing, and multiple transport components form a gradually decreasing height difference along the direction toward the guide member 32 (described below). The transportation of potatoes on the transport component is achieved through the interaction of the weight of the potatoes themselves and the rotation of the coil spring 313 and the mounting rod 312.

[0072] In this embodiment, the adjusting member 3113 includes a first fixed plate 31131, a movable portion 31132, and a second fixed plate 31133. The first fixed plate 31131 and the second fixed plate 31133 are fixedly connected to two different first linkage plates 3111 respectively. The movable portion 31132 is hingedly connected to the first fixed plate 31131. A movable groove is provided on the movable portion 31132. The second fixed plate 31133 is slidably connected to the movable groove. When in use, the second fixed plate 31133 can be adjusted in The sliding in the movable groove realizes the change of the inclination angle of the first fixed plate 31131 and the second fixed plate 31133. It should be noted that the first fixed plate 31131 and the second fixed plate 31133 are both linked with the first linkage plate 3111. When the inclination angles of the first fixed plate 31131 and the second fixed plate 31133 change, the inclination angles of the first linkage plate 3111 and the second linkage plate 3112 are also changed, thereby realizing the adjustment of the gap width between the two adjacent mounting rods 312.

[0073] In this embodiment, potatoes pass through the filter chain 22 and the primary screening feeding device 3 to remove broken soil from the material, and larger stones, soil blocks and rice straw are manually picked up and removed on the picking platform, so that the impurity content of potatoes is less than 20%, which is convenient for entering the next mechanism for sorting.

A first receiving mechanism is provided on one side of the secondary screening mechanism 33, and a second receiving structure is provided below the secondary screening mechanism 33. The secondary screening mechanism 33 screens the impurities dropped from the primary screening mechanism 31 and the potatoes with smaller volumes. The potatoes with smaller volumes are transported by the transport roller 332 and moved to the first receiving structure for collection under the action of the blocking roller 331. The impurities fall into the second receiving structure and are removed.

[0077] In this embodiment, a first fixing member 14 is provided on the mounting frame 1, and a guide member 32 is provided on one side of the primary screening mechanism 31. The two ends of the guide member 32 correspond to the primary screening mechanism 31 and the input conveyor belt 41 respectively. A second fixing member 321 is provided on the guide member 32. The two ends of the gap adjustment assembly 311 are fixedly connected to the first fixing member 14 and the first fixing member 14 respectively. The second fixing member 321 slides with the guide member 32 to ensure the stability of the primary screening mechanism 31.

[0078] In this embodiment, the guide member 32 includes a mounting portion 322, a sliding portion 323, a transmission roller 324, and a conveyor belt 325. The transmission roller 324 includes two groups and is respectively located at the mounting portion 322 and the sliding portion 323. The conveyor belt 325 is sleeved on the outer walls of the two groups of transmission rollers 324. The sliding portion 323 is slidingly connected to the mounting portion 322. The mounting portion 322 is fixedly connected to the mounting frame 1. The mounting portion 322 is slidingly matched with the second fixing member 321 to ensure the adjustment of the gap width between the two adjacent coil springs 313, and the sliding portion 323 can be slidably adjusted on the mounting portion 322, thereby realizing the adjustment of the length of the conveyor belt 325, which can enable the conveyor belt 325 to better cooperate with the primary screening mechanism 31, making the device more practical.

[0079] It should be noted that the guide member 32 supports the second fixing member 321. The position of the gap adjustment component 311 has been fixed under the action of the first fixing member 14 and the adjusting member 3113. When the gap adjustment component 311 adjusts the gap between two adjacent mounting rods 312, it is necessary to change the inclination angle of the first linkage plate 3111 and the second linkage plate 3112 and change their overall length. Therefore, the second fixing member 321 slides on the guide member 32 to ensure the stability of the gap adjustment component 311 during adjustment.

[0080] In this embodiment, the primary screening feeding device 3 cooperates with the guide member 32 to adjust the rotation speed of the mounting rod 312 and the transmission roller 324, that is, to adjust the transportation speed of the potatoes on the coil spring 313 and the conveyor belt 325, so that the material is evenly spread when entering the blanking conveying mechanism 4, making it convenient for the blanking conveying mechanism 4 to clean and remove the material.

[0081] In this embodiment, the blanking conveying mechanism 4 also includes a control center, and the detector 42 includes a detection unit 422. The detection unit 422 is located on opposite sides of the detection channel 421. The image information detected by the detection unit 422 is transmitted to the control center. The control center calculates and determines whether unqualified products have passed through the detection channel 421. When the detection unit 422 detects unqualified products, the control center controls the rejection component 43 to start.

[0082] Preferably, the detection unit 422 adopts a visual optical detection form, and the visual recognition range includes the entire detection channel 421. When potatoes pass through the detection channel 421, the detection unit 422 can distinguish the potatoes into qualified and unqualified products based on the color, size, and shape characteristics of the potatoes, and can distinguish impurities such as stones, rotten potatoes, and leaves. When the detection unit 422 detects impurities and unqualified products, it controls the rejection component 43 to start through the control center, so that the rejection rod 4321 works to change the landing trajectory of impurities and unqualified products, and completes the sorting. In other embodiments, the detection unit 422 can be set to various forms such as camera image acquisition detection and laser image acquisition detection. It should be noted that the detection unit 422 is a prior art, and those skilled in the art should be clear about its structure, principle, and usage method, etc., which are not described in detail here.

[0083] In this embodiment, the rejection assembly 43 includes a linkage rod 431 and a rotating mounting member 432 that rotates with the linkage rod 431. A rejection rod 4321 is provided on the rotating mounting member 432. A mechanical rebound member 433 is provided on one side of the rejection rod 4321. The two ends of the linkage rod 431 are respectively connected to the inner walls on both sides of the detection channel 421. When the rejection assembly 43 receives a rejection signal, it starts the rotating mounting member 432. The rotating mounting member 432 drives the rejection rod 4321 to rotate, so that the rejection rod 4321 blocks the falling trajectory of unqualified products, thereby achieving accurate sorting of potatoes during conveying. After the rotating mounting member 432 rotates, it resets to the left and right of the mechanical rebound member 433, is not easily damaged, and is more convenient to use.

[0084] In this embodiment, the rotating mounting member 432 includes a rotating portion 4322 and a linkage portion 4323. The rejection rod 4321 is located on the linkage portion 4323. A fixing frame 4331 is provided on the detector 42 on one side of the linkage portion 4323. The two ends of the mechanical rebound member 433 are respectively connected to the fixing frame 4331 and the rejection rod 4321. The rejection assembly 43 also includes a driving motor 436 electrically connected to the control center. A rotating shaft 4361 is provided on the driving motor 436. The rotating shaft 4361 is linked to the rotating portion 4322. The rotation direction and rotation speed of the rotating shaft 4361 and the rotating portion 4322 are synchronized, thereby realizing the linkage between the driving motor 436 and the rejection rod 4321. The rejection rod 4321 is reset in the form of mechanical rebound, which can reduce the energy consumption of the structure, and the mechanical rebound form is not prone to failure, which can extend the service life of the mechanism.

[0085] In this embodiment, the linkage connection between the rotating shaft 4361 and the rotating part 4322 is achieved by setting a transmission belt 4362, and the transmission belt 4362 is sleeved on the outer wall of the rotating part 4322 and the rotating shaft 4361. In other embodiments, the linkage connection between the rotating shaft 4361 and the rotating part 4322 is achieved by setting a chain, gear meshing, etc.

[0086] In other embodiments, the lengths of the rotating shaft 4361, the rotating part 4322, and the linkage part 4323 can be adjusted according to actual production needs, and the number of rotating mounting parts 432 can be set according to actual work requirements, so that the density and quantity of the removal rods 4321 on the linkage rod 431 can be adjusted.

[0087] In this embodiment, slide rails 423 for adjusting the position of the rejection component 43 are provided on both opposite sides of the inner wall of the detection channel 421, and the linkage rod 431 is slidably connected to the slide rails 423. The slide rails 423 include three groups and intersect with each other. The sliding directions of the three groups of slide rails 423 are horizontal, longitudinal and oblique respectively. Each group of slide rails 423 is provided with two groups of telescopic cylinders that are opposite to each other and are used to clamp the end of the linkage rod 431. The telescopic cylinder is connected to the control center signal. The control center sends a signal to the telescopic cylinder to make it run or stop, so as to realize the linkage rod 431 sliding along the slide rails 423 and switching the sliding direction at the intersection of the slide rails 423. The two groups of telescopic cylinders on each group of slide rails 423 drive the linkage rod 431 to slide on the slide rails 423 by clamping the end of the linkage rod 431, so that the position adjustment of the linkage rod 431 in the detection channel 421 is more convenient.

[0088] In this embodiment, the blanking conveying mechanism 4 also includes a blanking conveying component 44, which includes a qualified product conveyor belt 441 and an unqualified product conveyor belt 442. The potatoes enter the detection channel 421 along the input conveyor belt 41 and are detected by the detector 42. The detector 42, the rejection component 43, and the control center cooperate with each other to control whether the rotating part 226 rotates, and the qualified products fall unimpeded to the qualified product conveyor belt 441. When the rotating part 226 rotates, it drives the rejection rod 4321 to rotate, so that the rejection rod 4321 blocks the falling trajectory of the unqualified products and causes the unqualified products to fall to the unqualified product conveyor belt 442.

[0089] In this embodiment, along the horizontal transverse direction, the central axis of the linkage rod 431 is perpendicular to the central axis of the qualified product conveyor belt 441, and the central axis of the linkage rod 431 is parallel to the central axis of the unqualified product conveyor belt 442.

The qualified product conveyor belt 441 is tilted, and the tilt direction is downward away from the unqualified conveyor belt, and the tilt angle is 10°-30°. Baffles are provided on the side of the qualified product conveyor belt 441 facing the unqualified conveyor belt and on both sides adjacent to the side, which can enable qualified products to accurately enter the qualified product conveyor belt 441 and effectively prevent qualified products from falling.

[0090] In this embodiment, a recovery and transportation mechanism 5 is provided on one side of the blanking conveying mechanism 4, and the two ends of the recovery and transportation mechanism 5 correspond to the unqualified product conveyor belt 442 and the secondary screening mechanism 33 respectively. The height of the recovery and transportation mechanism 5 toward one end of the secondary screening mechanism 33 is higher than the height of the secondary screening mechanism 33. It should be noted that the detector 42 generally produces misjudgment. The material transported on the unqualified product conveyor belt 442 is transported to the recovery and transportation mechanism 5, and is dropped to the secondary screening mechanism 33 by the recovery and transportation mechanism 5 for re-screening. It should be noted that the recovery and transportation mechanism 5 is an existing technology, and those skilled in the art should be clear about its structure, principle and usage method, etc., which will not be described in detail here.

An impurity conveyor belt 61 corresponding to the filter chain platform 22 is provided on the frame 6 below the filter chain platform 22. The soil, leaves and other impurities filtered by the filter chain platform 22 are moved out of the picking chain platform 2 through the impurity conveyor belt 61, which can make the picking chain platform 2 more practical.

[0092] In this embodiment, a telescopic rod 15 is provided on the mounting frame 1. The fixed end of the telescopic rod 15 is fixedly connected to the mounting frame 1, and the movable end of the telescopic rod 15 is movably abutted against the ground. When the picking chain platform 2 is working, the movable end of the telescopic rod 15 is extended so that it abuts against the ground, which can make the picking chain platform 2 more stable during work. When the picking chain platform 2 completes its work, the movable end of the telescopic rod 15 can be retracted to avoid affecting the movement of the frame 6.
