DETAILED DESCRIPTION

[0033] 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.

[0034] An embodiment of a multifunctional fruit and vegetable cleaning machine of the present invention is as follows Figures 1 to 15 shown.

[0035] A multifunctional fruit and vegetable cleaning machine comprises a frame 100 and a first cleaning mechanism 200. A feeding table 110, a cleaning box 120 and a discharging table 130 are sequentially arranged on the frame 100 along a first direction, and the first direction is a horizontal direction. Figure 1 As shown, the first direction is the direction shown by the X axis. The cleaning box 120 contains cleaning liquid, and fruits and vegetables can enter from one side of the feeding platform 110 and be sent out from one side of the discharging platform 130 after passing through the cleaning box 120.

[0036] The first cleaning mechanism 200 is installed in the cleaning box 120. The first cleaning mechanism 200 includes a sensing plate 210, a trigger member 300 and a first cleaning part 220. The sensing plate 210 is installed on the cleaning box 120 through a first elastic member 211. The first elastic member 211 is arranged along the second direction. The first elastic member 211 is a spring. The second direction is a vertical direction, so that the sensing plate 210 can move up and down. Figure 1 As shown, the second direction is the direction shown by the Z axis.

[0037] The first cleaning section 220 includes two main cleaning groups 230, which are arranged in parallel in the first direction. Each main cleaning group 230 includes two cleaning brushes 240, which are arranged in sequence along a third direction, which is horizontal and perpendicular to the first direction. That is, the first cleaning section 220 includes four cleaning brushes 240. Figure 1 As shown, the third direction is the direction shown by the Y axis.

[0038] The cleaning brush 240 includes a rotating column 241, a plurality of upper bristles 242 and a plurality of lower bristles 243. The rotating column 241 passes through the induction plate 210 along the second direction and is installed on the cleaning box 120 so as to be rotatable around the second direction. The plurality of upper bristles 242 and the plurality of lower bristles 243 are both inclinedly arranged and evenly distributed around the second direction on the rotating column 241. The plurality of upper bristles 242 and the plurality of lower bristles 243 are arranged face to face along the second direction on the rotating column 241, and can promote the movement of fruits and vegetables between the plurality of upper bristles 242 and the plurality of lower bristles 243. The two cleaning brushes 240 of the main cleaning group 230 rotate in opposite directions and enable the fruits and vegetables to move to the side close to the discharge table 130. The downward movement of the induction plate 210 can drive the trigger member 300 to move, and the movement of the trigger member 300 can make the two main cleaning groups 230 approach each other in the first direction.

[0039] Specifically, the cleaning box 120 is connected to a plurality of nozzles through a water pipe 140, and the water pipe 140 is connected to a water pump through a valve, so that after the valve is opened, water can flow from the water pipe 140 through the nozzle into the cleaning box 120. The nozzle, the water pipe 140, the valve and the water pump are all prior art and will not be described in detail here.

[0040] In this embodiment, by setting the first cleaning mechanism 200, when in use, the fruits and vegetables to be cleaned are fed into the cleaning box 120 from one side of the feeding platform 110, and then the fruits and vegetables will enter the cleaning box 120. If the fruits and vegetables entering the cleaning box 120 do not touch the induction plate 210, it means that the fruits and vegetables cannot pass between the two main cleaning groups 230 arranged in parallel along the first direction, or only a small number of fruits and vegetables can pass between the two main cleaning groups 230 arranged in parallel along the first direction, that is, the cleaning brushes 240 of the two main cleaning groups 230 arranged in parallel along the first direction can block the fruits and vegetables from touching the bottom, and prevent the fruits and vegetables from directly contacting the induction plate 210, causing the induction plate 210 to move downward. At this time, the fruits and vegetables are normally cleaned and conveyed.

[0041] When the fruits and vegetables enter the cleaning box 120, the upper bristles 242 and the lower bristles 243 of the cleaning brush 240 will move the fruits and vegetables between the upper bristles 242 and the lower bristles 243, giving the fruits and vegetables a centering force to avoid the fruits and vegetables from hitting the sensing plate 210 or floating on the water surface as much as possible, and the surfaces of the fruits and vegetables are cleaned as the cleaning brush 240 rotates. Since the two cleaning brushes 240 of the main cleaning group 230 rotate in opposite directions, the fruits and vegetables can be cleaned by the cleaning brush 240 while being moved to the side close to the discharge table 130 under the promotion of the cleaning brush 240.

[0042] However, if fruits and vegetables can pass between the two main cleaning groups 230 arranged side by side in the first direction and cause the induction plate 210 to move downward, it means that a large number of fruits and vegetables are in contact with the induction plate 210. At this time, the induction plate 210 drives the trigger member 300 to move, and the trigger member 300 makes the two main cleaning groups 230 approach each other in the first direction, and then adjusts the spacing between the two main cleaning groups 230 in the first direction, so that when the fruits and vegetables of this type enter the cleaning box 120, they can be blocked by the cleaning brushes 240 of the two main cleaning groups 230 arranged side by side in the first direction, so as to avoid the fruits and vegetables from directly contacting the induction plate 210 and causing the fruits and vegetables to hit the induction plate 210. In addition, different types of fruits and vegetables can be adaptively adjusted and guided, so as to avoid the fruits and vegetables from floating on the water or colliding with the induction plate 210 as much as possible, so as to ensure the quality of the washed fruits and vegetables.

[0043] In this embodiment, two first cleaning parts 220 are provided. The two first cleaning parts 220 are arranged in parallel along the third direction in the cleaning box 120. Further, a plurality of first cleaning parts 220 are provided, and the plurality of first cleaning parts 220 are arranged in parallel along the third direction in the cleaning box 120.

[0044] In this embodiment, two first cleaning mechanisms 200 are provided. The two first cleaning mechanisms 200 are arranged in parallel along the first direction in the cleaning box 120. Further, multiple first cleaning mechanisms 200 are provided, and the multiple first cleaning mechanisms 200 are arranged in parallel along the first direction in the cleaning box 120.

[0045] The cleaning effect on fruits and vegetables can be improved by providing a plurality of first cleaning parts 220 and a plurality of first cleaning mechanisms 200 .

[0046] In this embodiment, the feeding table 110 is tilted on the frame 100, and the two ends of the feeding table 110 along the first direction are respectively called the first end and the second end. The first end is located on the side of the second end away from the cleaning box 120 in the first direction, and the first end is located above the second end.

[0047] Furthermore, a first guide plate 111 is provided on the feeding platform 110, the first guide plate 111 is located above the cleaning box 120, and the projection of the first guide plate 111 in the second direction is located between the two first cleaning parts 220. The first guide plate 111 has two first guide surfaces, and the two first guide surfaces can cause fruits and vegetables to fall on the two first cleaning parts 220 respectively.

[0048] By providing the first guide plate 111 , the fruits and vegetables falling from the feeding platform 110 are guided to prevent the fruits and vegetables from falling directly between the two first cleaning parts 220 and affecting the normal cleaning and conveying of the fruits and vegetables.

[0049] In this embodiment, the trigger 300 includes a limit column 310 and a limit assembly. The limit column 310 is arranged in the second direction in the cleaning box 120 and can only slide in the third direction. The first cleaning mechanism 200 also includes a first drive assembly 250. The first drive assembly 250 includes a first motor 251 and a first transmission belt 252. The first motor 251 is arranged on the cleaning box 120. A first driving pulley is fixedly arranged on the output shaft of the first motor 251. Each rotating column 241 extends out of the cleaning box 120 in the second direction. A first transmission pulley is fixedly arranged on one of the rotating columns 241 of each main cleaning group 230. The first transmission pulley is located below the cleaning box 120, and the first transmission pulleys correspondingly arranged on the two main cleaning groups 230 of the first cleaning part 220 are arranged side by side in the first direction. A driven pulley is rotatably provided on the limiting column 310 , and the driven pulley can rotate around the second direction relative to the limiting column 310 . The first transmission belt 252 is sequentially wound around the first driving pulley, the driven pulley and the first transmission pulley.

[0050] The two rotating columns 241 of the same main cleaning group 230 are connected by a first transmission member, and the first transmission member can make the two rotating columns 241 of the same main cleaning group 230 rotate in opposite directions, thereby making the two cleaning brushes 240 of the same main cleaning group 230 rotate in opposite directions, and can promote the movement of fruits and vegetables to the side close to the discharge platform 130. The two main cleaning groups 230 arranged side by side in the first direction are connected by a second elastic member 260, and the second elastic member 260 is arranged along the first direction. The second elastic member 260 always has a tendency to promote the two main cleaning groups 230 arranged side by side in the first direction to move away from each other along the first direction, and the second elastic member 260 is a compression spring. And one of the main cleaning groups 230 can slide on the induction plate 210 along the first direction, and the limit assembly is installed on the limit column 310, and the downward movement of the induction plate 210 can drive the limit assembly to move, and the action of the limit assembly can make the limit column 310 move along the third direction to the side away from the first motor 251.

[0051] Furthermore, the first transmission member includes two rotating gears 253 and two driven gears 254. The two rotating gears 253 are respectively arranged on the two rotating columns 241 of the same main cleaning group 230 and are located below the cleaning box 120. The two driven gears 254 are arranged in sequence along the third direction on the cleaning box 120 and rotate with the cleaning box 120. The two driven gears 254 are located between the two rotating gears 253 and mesh with each other, and the two rotating gears 253 are respectively meshed with the driven gears 254 adjacent to them.

[0052] Specifically, a connecting plate 270 is disposed between two rotating columns 241 of the same main cleaning group 230, the connecting plate 270 is disposed along the third direction, and both ends of the connecting plate 270 along the third direction are respectively rotatably connected to the rotating columns 241. The second elastic member 260 is disposed on the connecting plates 270 of the two main cleaning groups 230 disposed side by side along the first direction.

[0053] An annular protrusion is provided on the limiting column 310 around the second direction, and an annular groove is provided on the first transmission belt wheel. The annular groove and the annular protrusion are rotatably matched, so that the first transmission belt wheel can rotate around the second direction relative to the limiting column 310.

[0054] A first slide groove 121 is provided on the inner bottom wall of the cleaning box 120 . The first slide groove 121 is arranged along the third direction. The first slide groove 121 is a waist-shaped groove. The limiting column 310 is slidably installed in the first slide groove 121 , so that the limiting column 310 can slide on the cleaning box 120 along the third direction.

[0055] Two first interlocking grooves are provided on the inner bottom wall of the cleaning box 120. The two first interlocking grooves are respectively located at the two ends of the first slide 121 along the third direction and are connected to the first slide 121. Two first interlocking plates are provided on the limiting column 310. The two first interlocking plates are respectively located at the two ends of the limiting column 310 along the third direction. The first interlocking plates are not shown in the drawings, and the two first interlocking plates are provided in a one-to-one correspondence with the two first interlocking grooves. Each first interlocking plate is slidably installed in the first interlocking groove corresponding to it and will not fall out of the first interlocking groove corresponding to it. That is, the first interlocking plate is inserted into the first interlocking groove, and the first interlocking groove does not penetrate in the second direction.

[0056] By arranging the first interlocking plate and the first interlocking groove to cooperate, when the limiting column 310 moves along the third direction, the first interlocking plate will also move in the first interlocking groove and the first slide groove 121, and then as the limiting column 310 slides in the third direction, the first interlocking plate can always block the first slide groove 121 to prevent water from flowing out of the first slide groove 121. In addition, since the first interlocking plate cooperates with the first interlocking groove, the upward and downward movement and rotation of the limiting column 310 can be restricted, so that the limiting column 310 can only move in the third direction.

[0057] The induction plate 210 is provided with a plurality of rotating grooves 212 and a plurality of moving grooves 213, wherein the rotating grooves 212 are circular and the moving grooves 213 are waist-shaped. The plurality of rotating grooves 212 are sequentially arranged in the third direction, and the plurality of moving grooves 213 are sequentially arranged in the third direction, and the plurality of rotating grooves 212 and the plurality of moving grooves 213 are arranged in parallel in the first direction, and the two main cleaning groups 230 of the first cleaning part 220 are respectively referred to as the first main cleaning group and the second main cleaning group, and the cleaning brush 240 of the first main cleaning group is rotatably installed in the rotating groove 212, and the cleaning brush 240 of the second main cleaning group is rotatably installed in the moving groove 213, so that the second main cleaning group can move in the moving groove 213 along the first direction.

[0058] A sealing shell 150 is provided below the cleaning box 120. The sealing shell 150 is located above the first transmission member, corresponds to the multiple movable grooves 213 in the second direction, and abuts against the bottom wall of the cleaning box 120 through a sealing ring. Therefore, when the cleaning brush 240 of the second main cleaning group moves along the first direction, the sealing shell 150 can be used to receive the water in the movable groove 213 to prevent the water from flowing out of the movable groove 213.

[0059] In this embodiment, by providing a limiting column 310, a limiting assembly and a first driving assembly 250, when in use, the first motor 251 is started, and the first motor 251 rotates to drive the first active pulley to rotate, and the first driven pulley and the first transmission pulley are driven to rotate through the first transmission belt 252. The rotation of the first transmission pulley will drive the corresponding rotating column 241 to rotate, and then the plurality of rotating columns 241 can all rotate around the second direction through the first transmission member, and the first transmission belt 252 is kept taut through the second elastic member 260, and the two cleaning brushes 240 of the same main cleaning group 230 rotate in opposite directions, so that the fruits and vegetables are moved to the side close to the discharge table 130.

[0060] See attached Figure 8 and attached Fig. 9 As shown, with Figure 8 and attached Fig. 9 In the first cleaning mechanism 200 located on the left side, taking the main cleaning group 230 on the left side of the first cleaning part 220 located at the bottom as an example, the first motor 251 drives the first transmission belt 252 to rotate counterclockwise, so that the first transmission belt wheel located at the top rotates counterclockwise, drives the coaxial rotating gear 253 to rotate counterclockwise, and drives the rotating gear 253 located at the bottom clockwise through the two driven gears 254, so that the fruits and vegetables can move to the side close to the discharge table 130. Similarly, other main cleaning groups 230 also rotate in the same way.

[0061] If fruits and vegetables can pass between the two main cleaning groups 230 arranged in parallel in the first direction and cause the induction plate 210 to move downward, it means that a large amount of fruits and vegetables are in contact with the induction plate 210, and when the induction plate 210 moves downward, it can drive the limit assembly to act, and the action of the limit assembly can cause the limit column 310 to move along the third direction to the side away from the first motor 251, and the movement of the limit column 310 will cause the two main cleaning groups 230 to approach each other in the first direction through the first transmission belt 252, thereby adjusting the spacing between the two main cleaning groups 230 in the first direction and compressing the second elastic member 260, so that when the fruits and vegetables enter the cleaning box 120, they can be blocked by the cleaning brushes 240 of the two main cleaning groups 230 arranged in parallel along the first direction, thereby preventing the fruits and vegetables from directly contacting the induction plate 210 and causing the fruits and vegetables to hit the induction plate 210.

[0062] In this embodiment, the limiting assembly includes a first limiting block 320, a first limiting rod 330, a second limiting block 340 and a plurality of limiting teeth 350. The first limiting block 320 is plugged into the induction plate 210 and can slide on the limiting rod 310 along the second direction. The first limiting rod 330 is arranged along the third direction and fixedly mounted on the inner side wall of the cleaning box 120. The first limiting rod 330 is sequentially provided with a plurality of limiting tooth blocks along the third direction. The first limiting block 320 and the plurality of limiting tooth blocks are arranged face to face in the second direction. The first limiting block 320 includes a first tooth surface 321 and a second tooth surface 322. The first tooth surface 321 is arranged along the second direction, and the second tooth surface 322 is inclined relative to the first tooth surface 321. A guide groove 360 ​​is defined between each two adjacent limiting tooth blocks arranged in the third direction. In the initial state, the first limiting block 320 is located above the guide groove 360, and the second tooth surface 322 of the first limiting block 320 contacts the inner wall of the guide groove 360.

[0063] The second limit block 340 is installed on the limit column 310 through a third elastic member, the third elastic member is arranged along the second direction, the third elastic member is a spring, and the third elastic member is not shown in the drawings. The second limit block 340 includes a third tooth surface 341 and a fourth tooth surface 342, the third tooth surface 341 and the fourth tooth surface 342 are both inclined, and the third tooth surface 341 is located on the side of the fourth tooth surface 342 close to the induction plate 210 in the third direction. A plurality of limit teeth 350 are arranged in sequence along the third direction in the cleaning box 120 and are fixedly connected to the cleaning box 120. A slot 370 is defined between each two adjacent limit teeth 350 arranged in the third direction, and the second limit block 340 is located in the slot 370 in the initial state. And when the first limit block 320 is located in the guide groove 360, the third tooth surface 341 of the second limit block 340 will abut against the inner wall of the slot 370 and be located above the slot 370.

[0064] In this embodiment, the first limit block 320, the first limit rod 330, the second limit block 340 and the plurality of limit teeth 350 are provided. When the sensing plate 210 moves downward, the first limit block 320 is driven to move downward synchronously, so that the second tooth surface 322 of the first limit block 320 moves downward along the inner wall of the guide groove 360, and under the guidance of the guide groove 360, the first limit block 320 moves in the third direction relative to the sensing plate 210, that is, referring to the attached Fig.13 As shown, with Fig.13 The first limit block 320 moves to the right, and the movement of the first limit block 320 drives the limit column 310 to move synchronously, so that the limit column 310 moves along the third direction to the side away from the first motor 251. That is, under the promotion of the induction plate 210, the first limit block 320 moves downward and rightward at the same time, and drives the limit column 310 to move rightward synchronously.

[0065] The movement of the limiting column 310 will drive the second limiting block 340 to move synchronously, giving the second limiting block 340 a force to move in the third direction, so that the second limiting block 340 can slide upward along the slot 370 to the top of another slot 370, and make the third tooth surface 341 abut against the inner wall of the slot 370. That is, under the urging of the limiting column 310, the second limiting block 340 moves rightward and upward at the same time.

[0066] At this time, although the third elastic member has a tendency to push the second limit block 340 to reset downward, the downward movement of the second limit block 340 will push the limit column 310 to move in the third direction, that is, the limit column 310 moves to the right, but since the first limit block 320 is located in the guide groove 360, the movement of the first limit block 320 will drive the guide groove 360 ​​to move, so that the first limit rod 330 moves. However, the first limit rod 330 is fixed in the cleaning box 120 and cannot move, so at this time, even if the second limit block 340 has a tendency to reset downward, it cannot reset downward under the restriction of the first limit block 320 and the first limit rod 330.

[0067] And when the limiting post 310 moves to the right, that is, when the limiting post 310 moves along the third direction away from the first motor 251, the two main cleaning groups 230 will be brought closer to each other in the first direction, and then the distance between the two main cleaning groups 230 in the first direction will be adjusted, so that when the fruits and vegetables of this type enter the cleaning box 120, they can be blocked by the cleaning brushes 240 of the two main cleaning groups 230 arranged in parallel along the first direction, avoiding direct contact between the fruits and vegetables and the induction plate 210, so that the fruits and vegetables do not hit the induction plate 210.

[0068] When the induction plate 210 is reset and moves upward, it will drive the first limit block 320 to move upward synchronously, so that the first limit block 320 moves upward out of the guide groove 360, and the first limit rod 330 is disengaged from the first limit block 320, and no longer restricts the first limit block 320 from moving downward. At this time, the third elastic member will cause the second limit block 340 to reset downward, so that the third tooth surface 341 of the second limit block 340 slides along the inner wall of the slot 370 until the second limit block 340 is in the next slot 370. That is, under the urging of the third elastic member, the second limit block 340 moves downward and rightward, and synchronously drives the limit column 310 to move rightward. The movement of the limit column 310 will drive the first limit block 320 to move rightward synchronously, so that the first limit block 320 is again above the next guide groove 360, and its second tooth surface 322 will also abut against the inner wall of the guide groove 360. That is, the limit assembly will be attached to the Fig.13 The status shown moves to the Fig.14 Waiting for the induction plate 210 to move down again.

[0069] Specifically, the limiting column 310 is provided with a first limiting groove 311, and the first limiting block 320 is slidably matched with the first limiting groove 311. The limiting column 310 is provided with a second limiting groove 312, and the second limiting block 340 is installed in the second limiting groove 312 through a third elastic member.

[0070] Furthermore, two limiting assemblies are provided, and the two limiting assemblies are symmetrically arranged about the central axis of the limiting column 310 in the third direction.

[0071] In this embodiment, a multifunctional fruit and vegetable cleaning machine further includes a second cleaning mechanism 400, which is installed in the cleaning box 120 and is located on the side of the first cleaning mechanism 200 away from the feeding platform 110 in the first direction. The second cleaning mechanism 400 includes two second cleaning parts 410, and the two second cleaning parts 410 are arranged in parallel along the third direction on the cleaning box 120. The second cleaning part 410 includes two auxiliary cleaning groups, which are arranged in parallel in the first direction, and each auxiliary cleaning group includes two roller brushes 420, which are arranged in sequence along the third direction. That is, the second cleaning part 410 includes four roller brushes 420.

[0072] The roller brush 420 includes a rolling column, an upper roller brush and a lower roller brush. The rolling column is arranged along the second direction and can be installed in the cleaning box 120 to rotate around the second direction. The upper roller brush and the lower roller brush are both arranged on the rolling column and face to face along the second direction on the rolling column. The upper roller brush and the lower roller brush each include a plurality of hard long bristles and a plurality of soft short bristles, and the plurality of hard long bristles and the plurality of soft short bristles of the upper roller brush are all left-handed, and the plurality of hard long bristles and the plurality of soft short bristles of the lower roller brush are all right-handed, and can promote the movement of fruits and vegetables between the upper roller brush and the lower roller brush. The two roller brushes 420 of the auxiliary cleaning group rotate in opposite directions and enable the fruits and vegetables to move to the side close to the discharge table 130.

[0073] The second cleaning mechanism 400 further includes a second driving assembly 430, which includes a second motor 431 and a second transmission belt 432. The second motor 431 is disposed on the cleaning box 120, and a second driving pulley is fixedly disposed on the output shaft of the second motor 431. Each rolling column extends out of the cleaning box 120 in the second direction, and a second transmission pulley is fixedly disposed on one of the rolling columns of each auxiliary cleaning group. The second transmission pulley is located below the cleaning box 120, and the second transmission pulleys correspondingly disposed on the two auxiliary cleaning groups of the second cleaning part 410 are arranged side by side in the first direction. The second transmission belt 432 is sequentially wound around the second driving pulley and the second transmission pulley.

[0074] The two rolling cylinders of the same auxiliary cleaning group are connected by a second transmission member, which can make the two rolling cylinders in the same auxiliary cleaning group rotate in opposite directions, thereby making the two roller brushes 420 of the same auxiliary cleaning group rotate in opposite directions, and can promote the fruits and vegetables to move to the side close to the discharge table 130. The structure and principle of the second transmission member are the same as those of the first transmission member, and will not be repeated.

[0075] Furthermore, a second guide plate 112 is provided in the cleaning box 120, and the second guide plate 112 is located between the first cleaning mechanism 200 and the second cleaning mechanism 400. The projection of the second guide plate 112 in the first direction is located between the two second cleaning parts 410. The second guide plate 112 has two second guide surfaces, and the two second guide surfaces can cause fruits and vegetables to move to the two second cleaning parts 410 respectively.

[0076] By providing the second guide plate 112 , the fruits and vegetables cleaned by the first cleaning mechanism 200 are guided to prevent the fruits and vegetables from moving between the two second cleaning parts 410 and affecting the normal cleaning and conveying of the fruits and vegetables.

[0077] In this embodiment, the second cleaning mechanism 400 is provided. After the fruits and vegetables are cleaned by the first cleaning mechanism 200, they will come to the second cleaning mechanism 400, that is, come to between the two roller brushes 420 of the auxiliary cleaning group. The fruits and vegetables are moved between the upper roller brush and the lower roller brush by using the hard long bristles and the soft short bristles with opposite rotation directions respectively provided on the upper roller brush and the lower roller brush, and the force to center the fruits and vegetables is applied to avoid the fruits and vegetables from floating on the water surface or sinking and contacting the inner bottom wall of the cleaning box 120. The soft short bristles can clean the fruits and vegetables, and further ensure the quality of the cleaned fruits and vegetables.

[0078] In this embodiment, the discharge platform 130 is tilted on the cleaning box 120, and the two ends of the discharge platform 130 along the first direction are respectively called the third end and the fourth end, the third end is located on the side of the fourth end close to the cleaning box 120 in the first direction, and the fourth end is located above the third end. A collecting plate 160 is provided on the frame 100, and the collecting plate 160 is provided at the fourth end of the discharge platform 130.

[0079] Specifically, the discharge table 130 includes a drain belt 131 and two pulley shafts. The two pulley shafts are installed on the frame 100 and can rotate around the third direction on the frame 100. The two pulley shafts are respectively located at the third end and the fourth end of the discharge table 130. The drain belt 131 is wound around the two pulley shafts, and a plurality of synchronous plates 132 are evenly distributed in the circumferential direction of the drain belt 131, so that the drain belt 131 can rotate around the third direction.

[0080] By setting up the drain belt 131 and two belt shafts, after the fruits and vegetables are cleaned by the second cleaning mechanism 400, they will come between the second cleaning mechanism 400 and the discharge table 130. As the drain belt 131 continues to rotate, the fruits and vegetables will be transferred from the cleaning box 120 to the drain belt 131 driven by the synchronous plate 132, leave the cleaning box 120 and move synchronously with the drain belt 131, and be collected after passing through the collecting plate 160, waiting for subsequent processing.

[0081] In combination with the above embodiments, the specific working process is as follows:

[0082] When in use, the fruits and vegetables to be washed are fed into the washing box 120 from one side of the feeding table 110 , and then the fruits and vegetables enter the washing box 120 . If the fruits and vegetables entering the washing box 120 do not touch the induction plate 210 , the fruits and vegetables are washed and conveyed normally.

[0083] When the fruits and vegetables enter the cleaning box 120, the upper bristles 242 and the lower bristles 243 of the cleaning brush 240 will move the fruits and vegetables between the upper bristles 242 and the lower bristles 243, giving the fruits and vegetables a centering force to avoid the fruits and vegetables from hitting the sensor plate 210 or floating on the water surface as much as possible, and the surfaces of the fruits and vegetables are cleaned as the cleaning brush 240 rotates.

[0084] However, if the fruits and vegetables can pass between the two main cleaning groups 230 arranged in parallel in the first direction and the induction plate 210 moves downward, when the induction plate 210 moves downward, the first limit block 320 will be driven downward synchronously, so that the second tooth surface 322 of the first limit block 320 moves downward along the inner wall of the guide groove 360, and under the guidance of the guide groove 360, the first limit block 320 moves in the third direction relative to the induction plate 210, that is, referring to FIG. Fig.13 As shown, with Fig.13 The first limit block 320 moves to the right, and the movement of the first limit block 320 drives the limit column 310 to move synchronously, so that the limit column 310 moves along the third direction to the side away from the first motor 251. That is, under the promotion of the induction plate 210, the first limit block 320 moves downward and rightward at the same time, and drives the limit column 310 to move rightward synchronously.

[0085] The movement of the limiting column 310 will drive the second limiting block 340 to move synchronously, giving the second limiting block 340 a force to move in the third direction, so that the second limiting block 340 can slide upward along the slot 370 to the top of another slot 370, and make the third tooth surface 341 abut against the inner wall of the slot 370. That is, under the urging of the limiting column 310, the second limiting block 340 moves rightward and upward at the same time.

[0086] At this time, although the third elastic member has a tendency to push the second limit block 340 to reset downward, the downward movement of the second limit block 340 will push the limit column 310 to move in the third direction, that is, the limit column 310 moves to the right, but since the first limit block 320 is located in the guide groove 360, the movement of the first limit block 320 will drive the guide groove 360 ​​to move, so that the first limit rod 330 moves. However, the first limit rod 330 is fixed in the cleaning box 120 and cannot move, so at this time, even if the second limit block 340 has a tendency to reset downward, it cannot reset downward under the restriction of the first limit block 320 and the first limit rod 330.

[0087] When the limiting column 310 moves to the right, that is, when the limiting column 310 moves along the third direction away from the first motor 251, the two main cleaning groups 230 will be brought closer to each other in the first direction, and then the distance between the two main cleaning groups 230 in the first direction will be adjusted, so that when the fruits and vegetables of this type enter the cleaning box 120, they can be blocked by the cleaning brushes 240 of the two main cleaning groups 230 arranged in parallel along the first direction, so as to prevent the fruits and vegetables from directly contacting the induction plate 210 and causing the fruits and vegetables to hit the induction plate 210. After the induction plate 210 moves up, the entire limiting assembly will reset and wait for the induction plate 210 to move down again.

[0088] After the fruits and vegetables are cleaned by the first cleaning mechanism 200, they will come to the second cleaning mechanism 400, that is, between the two roller brushes 420 of the auxiliary cleaning group. The fruits and vegetables are moved between the upper roller brush and the lower roller brush by using the hard long bristles and the soft short bristles with opposite rotation directions respectively provided on the upper roller brush and the lower roller brush, giving the fruits and vegetables a force to center, and trying to prevent the fruits and vegetables from floating on the water surface or sinking and contacting the bottom wall of the cleaning box 120. The soft short bristles can clean the fruits and vegetables, further ensuring the quality of the cleaned fruits and vegetables.

[0089] After the fruits and vegetables are cleaned by the second cleaning mechanism 400, they will come between the second cleaning mechanism 400 and the discharge table 130. As the drain belt 131 continues to rotate, the fruits and vegetables will be transferred from the cleaning box 120 to the drain belt 131 driven by the synchronous plate 132, leave the cleaning box 120 and move synchronously with the drain belt 131, and be collected after passing through the collecting plate 160, waiting for subsequent processing.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
