[0022] The present invention has the following beneficial effects:

[0023] 1. The potato processing and screening device is provided with a collecting hopper for temporarily storing potatoes under the rolling bar. When the potatoes reach a certain amount, the door panel opens and the potatoes fall into the washing basket. When the door panel opens, the pressure rod presses the washing basket below the water surface in the washing tank. Before the potatoes fall into the washing basket, they will first contact the water surface. The water in the washing tank has a certain buffering effect on the potatoes, thereby effectively reducing the situation where the potatoes fall and are damaged. In addition, the potatoes are completely immersed in water during washing.

When the speed reducer descends, the rotating plate opens and the cleaning basket moves down smoothly. When the speed reducer rises, the rotating plate closes. Under the action of water resistance, the speed reducer rises slowly, thereby achieving the effect of extending the rising time of the cleaning basket, thereby achieving the effect of extending the potato rinsing time.

[0025] 3. The potato processing and screening device has a protrusion installed on one side of the enclosure, and the cross section of the protrusion is semicircular. A wave plate is provided on the inner wall of the cleaning tank, and a plurality of protrusions are evenly provided on the wave plate.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1: This embodiment is intended to promote the solution of the problem that for some potatoes with a lot of soil attached, simple rinsing cannot completely clean the potatoes and the cleaning effect is poor. Please refer to Figures 1 to 10 A potato processing and screening device includes a screening bracket 101, on which a roller 200 for screening potatoes is installed, and a feed hopper 100 is arranged above the roller 200. The device also includes a motor (not shown in the figure) for driving the roller 200 to move. The roller 200 moves to one side under the drive of the motor, and the gap between adjacent rollers 200 gradually increases, so that potatoes of different sizes fall down one after another, thereby achieving the effect of screening potatoes. Screening using the roller 200 is a common technical means, which is well known to technicians in this field, so it will not be repeated here.

[0040] In addition, a cleaning bracket 602 is provided below the roller 200, and a collecting hopper 301 is installed on the upper part of the cleaning bracket 602. The potatoes screened by the roller 200 will fall into the collecting hopper 301 and then be temporarily stored in the collecting hopper 301. A door panel 308 is hingedly installed at the lower end of the collecting hopper 301, and a switch spring 304 is installed on the cleaning bracket 602. When the potatoes stored in the collecting hopper 301 reach a certain amount, the switch spring 304 is compressed, the door panel 308 opens, and the potatoes in the collecting hopper 301 fall down.

[0041] A cleaning trough 601 is provided at the lower part of the cleaning bracket 602, and water for washing potatoes is contained in the cleaning trough 601. A cleaning basket 401 is provided above the cleaning trough 601, and potatoes in the collecting hopper 301 fall into the cleaning basket. A baffle 402 is hinged at one end of the cleaning basket 401, and a plurality of through holes 409 are provided at the bottom of the baffle 402 and the cleaning basket 401. A side plate 407 is installed at the side of the cleaning basket 401, and a pressure rod 305 is provided above the surrounding plate 407. One end of the pressure rod 305 abuts against the surrounding plate 407, and the other end of the pressure rod 305 is transmission-connected to the door panel 308. A second return spring 606 is provided below the cleaning basket 401, and the second return spring 606 is installed inside the cleaning trough 601.

[0042] Please note that, please refer to Figure 1-2 , the washing basket 401 is initially located above the water surface. When the baffle 402 is opened, the washing basket 401 is pressed into the water by the pressure rod 305, and then the potatoes fall into the water. The water has a buffering effect on the potatoes to prevent the potatoes from being damaged. In addition, since the size of the washing basket 401 is smaller than that of the washing tank 601, a baffle 402 and a panel 407 are provided. The baffle 402 and the panel 407 both have the effect of preventing the potatoes from rolling into the washing tank 601. Among them, when the washing basket 401 is on the water surface, one end of the baffle 402 is placed on the top of the washing tank 601. When the washing basket 401 is located below the water surface, the baffle 402 rotates inward and closes the washing basket 401. In addition, under the action of the second reset spring 606, the washing basket 401 will gradually reset, move above the water surface, and drain the potatoes.

[0043] For details, please refer to Figure 2-6 A sliding rod 307 is installed on the cleaning bracket 602, and a switch slider 303 is slidably installed on the sliding rod 307. A first connecting rod 302 is hinged on one side of the switch slider 303, and one end of the first connecting rod 302 is hinged on the door panel 308. One end of the switch slider 303 is fixedly connected to one end of the switch spring 304, and the other end of the switch spring 304 is installed on the cleaning bracket 602. One side of the switch slider 303 is fixedly connected to the top end of the pressure rod 305, and the bottom end of the pressure rod 305 is in conflict with the enclosure 407.

[0044] It should be noted that before the door panel 308 is opened, the pressure of a small amount of potatoes on the door panel 308 is transmitted to the first connecting rod 302. Due to the large angle between the first connecting rod 302 and the slide bar 307, the force on the first connecting rod 302 is mainly decomposed in the direction perpendicular to the slide bar 307. Therefore, the switch slider 303 hardly moves and the door panel 308 hardly rotates. When the weight of the potatoes reaches a certain level, the component of the force on the first connecting rod 302 in the direction parallel to the slide bar 307 will cause the switch slider 303 to move downward significantly. The more the switch slider 303 moves downward, the smaller the angle between the first connecting rod 302 and the slide bar 307 is, resulting in a greater component of the force on the first connecting rod 302 in the direction parallel to the slide bar 307, further pushing the switch slider 303 downward, so that the door panel 308 is fully opened. This process is short, thereby ensuring the function of the collecting hopper 301 to store a certain amount of potatoes and release potatoes.

[0045] In this embodiment: a collecting hopper 301 for temporarily storing potatoes is arranged below the rolling bar 200. When the potatoes reach a certain amount, the door panel 308 opens and the potatoes fall into the cleaning basket 401. In the process of opening the door panel 308, the door panel 308 drives the switch slider 303 to move downward through the hinged first connecting rod 302, and a pressure rod 305 is installed on one side of the switch slider 303. The bottom end of the pressure rod 305 conflicts with the enclosure 407 on the cleaning basket 401. Therefore, when the door panel 308 is opened, the pressure rod 305 presses the cleaning basket 401 below the water surface in the cleaning tank 601. At this time, the baffle 402 is closed to prevent the potatoes from rolling into the cleaning tank 601. After washing is completed, since a second return spring 606 is provided under the washing basket 401, the washing basket 401 is reset under the elastic force of the second return spring 606, the potatoes are drained of water, and the baffle 402 is opened to facilitate the removal of the potatoes. In this process, the potatoes will first contact the water surface before falling into the washing basket 401. The water in the washing trough 601 has a certain buffering effect on the potatoes, thereby effectively reducing the situation where the potatoes will be damaged when falling. In addition, the potatoes are completely immersed in water during washing, and the dirt and dust on the surface of the potatoes will fall off due to the infiltration of water, thereby improving the washing effect. In addition, the water in the washing trough 601 can be reused, thereby reducing the waste of water resources.

[0046] Embodiment 2: This embodiment is intended to promote the solution of the problem that the reset process of the washing basket 401 is short, resulting in insufficient potato washing time. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 10, a deceleration plate 501 is arranged below the washing basket 401, a push plate 408 is installed at the bottom of the washing basket 401, the bottom end of the push plate 408 is in conflict with the deceleration plate 501, a first water hole 505 is provided on the deceleration plate 501, and two first water holes 505 are symmetrically arranged, a rotating plate 503 is hinged on the deceleration plate 501, the rotating plate 503 is arranged adjacent to the first water hole 505, and a second water hole 509 is also provided on the rotating plate 503. Therefore, when the washing basket 401 moves downward, the deceleration plate 501 will be pushed to move, and the rotating plate 503 will rotate and open under the resistance of water, and the water will pass through the first water hole 505, and the washing basket 401 will move downward smoothly. In addition, when the deceleration plate 501 moves upward, the rotating plate 503 is closed, so there is a large resistance between the deceleration plate 501 and the water, and the deceleration plate 501 moves up slowly, so as to achieve the effect of deceleration when the washing basket 401 is reset.

[0047] For details, please refer to Figure 4 , Figure 6 , Figure 7 , a support column 506 is installed at the bottom end of the deceleration plate 501, a sleeve 603 is installed inside the cleaning tank 601, a second return spring 606 is installed in the sleeve 603, one end of the second return spring 606 is connected to the bottom end of the support column 506, and the support column 506 is slidably installed in the sleeve 603, and a compression spring 604 is also installed in the sleeve 603. When the potatoes completely fall into the cleaning basket 401, the compression spring 604 is compressed, and the compression amount of the compression spring 604 is greater than the compression amount of the second return spring 606. The compression spring 604 is arranged on the side adjacent to the baffle 402. Therefore, when the potatoes are in the cleaning basket 401, since the compression amount of the compression spring 604 is greater than the compression amount of the second return spring 606, the downward displacement of the support column 506 on the side adjacent to the baffle 402 is relatively large, so that one end of the discharge port of the cleaning basket 401 is tilted downward, so that the potatoes can be fished out smoothly.

[0048] Also, please refer to Figure 4 , Figure 6 A plurality of limit posts 502 are symmetrically mounted on the deceleration plate 501 , one side of the limit posts 502 is in sliding contact with the enclosure 407 , and the limit posts 502 are used to limit the movement of the cleaning basket 401 in the horizontal plane to prevent the cleaning basket 401 from deflecting and becoming unstable.

[0049] In this embodiment: because the cleaning basket 401 will quickly return to its original position under the action of the second return spring, a deceleration plate 501 for limiting the speed of the cleaning basket 401 is arranged at the lower side of the cleaning basket 401, and a push plate 408 is installed at the bottom of the cleaning basket 401, and the bottom end of the push plate 408 conflicts with the push plate 408. When the cleaning basket 401 moves downward, the deceleration plate 501 will be pushed downward by the push plate 408, and a support column 506 is installed at the bottom end of the push plate 408, and a sleeve 603 is installed inside the cleaning tank 601, and a second return spring 606 is installed in the sleeve 603, and one end of the second return spring 606 is connected to the bottom end of the support column 506, and the support column 506 is slidably installed in the sleeve 603, and the second return spring 606 is installed in the sleeve 603. Under the action of the positioning spring 606, the deceleration plate 501 will move upward, thereby pushing the push plate 408 to reset the cleaning basket 401. In order to reduce the resistance of the deceleration plate 501 when it moves downward, a water hole No. 1 505 is opened on the deceleration plate 501. In addition, a limiting column 502 is installed on the deceleration plate 501 to limit the cleaning basket 401 to prevent the cleaning basket 401 from becoming unstable when it descends or ascends. At the same time, in order to increase the resistance of the deceleration plate 501 when it ascends, a rotating plate 503 is arranged near the water hole No. 1 505. The rotating plate 503 is opened when the deceleration plate 501 descends, and is closed when it ascends, thereby achieving the effect of extending the rising time of the cleaning basket 401, thereby achieving the effect of extending the potato rinsing time.

[0050] Embodiment 3: This embodiment is intended to promote the solution of separating the potatoes gathered in the washing basket 401, allowing the potatoes to fully contact the water, and further improve the washing effect. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figures 1 to 10 , a protrusion 403 is installed on one side of the enclosure 407, and the cross section of the protrusion 403 is semicircular, a wave plate 605 is arranged on the inner wall of the cleaning tank 601, and a plurality of protrusions 403 are evenly arranged on the wave plate 605, and the enclosure 407 is in sliding contact with the protrusions 403 on the wave plate 605. In addition, a limit block 507 is installed on the deceleration plate 501, and a limit spring 508 is installed on one end of the limit block 507, and the other end of the limit spring 508 is installed on the push plate 408. In the specific implementation, the surface of the protrusion 403 should be as smooth as possible, and when the enclosure 407 and the protrusion 403 on the wave plate 605 slide relative to each other, the cleaning basket 401 will swing back and forth.

[0051] Also, please refer to Figure 4 , Figure 8A paddle plate 404 is movably arranged inside the washing basket 401, and the paddle plate 404 is used to separate the accumulated potatoes, and the paddle plate 404 is in transmission connection with the rotating plate 503. Specifically, a second connecting rod 405 is installed on one side of the paddle plate 404, and a rectangular slider 406 is installed on one end of the second connecting rod 405. A first slide groove 410 is provided on the enclosure 407, and the rectangular slider 406 is slidably installed in the first slide groove 410. A mounting plate 414 is installed on one side of the rectangular slider 406, and a first return spring 415 is installed on one side of the mounting plate 414, and the other end of the first return spring 415 is installed on the enclosure 407. The purpose of the first return spring 415 is to help the paddle plate 404 to return to its original position.

[0052] In addition, an arc rod 504 is hinged on the top of the rotating plate 503, and an insertion block 412 is hinged on the other end of the arc rod 504. The cross-section of the insertion block 412 is triangular. A No. 2 slide groove 411 is opened on the enclosure 407. The No. 2 slide groove 411 is located below the No. 1 slide groove 410, and the No. 2 slide groove 411 is connected to the No. 1 slide groove 410. The insertion block 412 is slidably installed in the No. 2 slide groove 411. A slot 413 is opened on the rectangular slider 406, and the insertion block 412 is inserted into the slot 413.

[0053] It should be noted that the movement direction of the speed reducer 501 is straight up and down, while the cleaning basket 401 can move in the horizontal plane. A second connecting rod 405 is connected between the speed reducer 501 and the cleaning basket 401. Therefore, in order to ensure that the cleaning basket 401 moves normally in the horizontal plane, the width of the slot 413 should be greater than the width of the insertion block 412, so that the insertion block 412 can not only be inserted into the slot 413 in the vertical direction, but also maintain sliding contact with the slot 413 in the horizontal direction, thereby ensuring that the cleaning basket 401 moves smoothly in the horizontal direction.

[0054] In this embodiment: a protrusion is installed on one side of the enclosure 407, and the cross-section of the protrusion is semicircular. A wave plate 605 is arranged on the inner wall of the cleaning tank, and a plurality of protrusions are evenly arranged on the wave plate 605. The enclosure 407 and the protrusions on the wave plate 605 are in sliding contact with each other. Therefore, the cleaning basket 401 will move back and forth to both sides during the up and down movement, thereby shaking the gathered potatoes apart. On the one hand, each potato can fully contact the water, and on the other hand, the potatoes rub against each other, which is conducive to cleaning the soil. In addition, a paddle 404 is movably arranged inside the cleaning basket 401. The paddle 404 is used to separate the accumulated potatoes. The paddle 404 is transmission-connected to the rotating plate 503. When the rotating plate 503 is opened, the paddle 404 is driven to move to both sides. The paddle 404 separates the gathered potatoes, further achieving the effect of making each potato fully contact the water and rubbing against each other, which is conducive to cleaning the soil.
