[0030] Example 1

[0031] Reference Figures 1-4 The first embodiment of this application provides a fruit and vegetable washing and sorting device, including: a workbench 10, which has a washing area and a sorting area arranged sequentially along a first direction; a washing component 20, which is disposed in the washing area, the washing component 20 including at least two first washing brushes 21 arranged along the first direction; a sorting component, which is disposed in the sorting area, the sorting component including a screening component 30 and conveying components disposed on both sides of the screening component 30, a screening channel 31 is formed between the screening component 30 and the conveying components, the width of the screening channel 31 gradually increases along the first direction, a collection frame 50 is disposed below the workbench 10, at least two partitions 51 are disposed inside the collection frame 50, the collection frame 50 is divided into multiple collection areas 52 by the partitions 51, the distance between adjacent partitions 51 or between the partitions 51 and the inner wall of the collection frame 50 is adjustable, so that the length of each collection area 52 is adjustable in the first direction.

[0032] In this embodiment, as Figure 1 As shown, the left and right directions are the first directions, such as... Figure 2 As shown, X represents the first direction and Y represents the second direction. Figure 1In the diagram, M represents the length of the cleaning zone in the first direction, and N represents the length of the sorting zone in the first direction. The cleaning zone is used to clean the fruits and vegetables, which are typically nearly spherical in shape. The cleaning assembly 20 includes multiple first cleaning brushes 21, the upper surfaces of which can be located within a positioning plane. This positioning plane can be parallel to a horizontal plane, and it can also gradually slope downwards along the conveying direction to facilitate guiding the fruits and vegetables from the cleaning assembly 20 to the sorting assembly. The sorting assembly sorts the fruits and vegetables. The sorting component 30 extends along the first direction and has guide surfaces on both sides. The distance between the guide surfaces and the conveyor gradually increases along the first direction, meaning the width of the sorting channel 31 gradually increases away from the cleaning assembly 20 along the first direction. The conveyor can move the fruits and vegetables in the sorting channel 31 away from the cleaning assembly 20 along the first direction. Fruits and vegetables of different sizes can fall below the sorting channel 31 at different positions. A collection frame 50 is provided below the screening channel 31. At least two partitions 51 are provided within the collection frame 50, dividing the space within the collection frame 50 into multiple collection areas 52. By setting the positions of the partitions 51 within the collection frame 50, the space between adjacent partitions 51, or the space between a partition 51 and the inner wall of the collection frame 50, varies, allowing for adaptive adjustment of the size of the fruits and vegetables corresponding to the collection areas 52. All collection areas 52 are arranged along a first direction.

[0033] Example 2

[0034] As an optional implementation, this embodiment provides a specific structure of a fruit and vegetable washing and sorting device, including: an inclined feeding component 60 is also provided on the workbench 10, the lower end of the feeding component 60 is located in the washing area, and the feeding component 60 has at least one feeding channel 61 for conveying the fruits and vegetables to be washed.

[0035] Specifically, by setting up the feeding component 60, the feeding component 60 can sort and feed the fruits and vegetables, so that the fruits and vegetables can be sequentially transported to the cleaning component 20 along the feeding channel 61.

[0036] Optionally, the cleaning assembly 20 also includes two side guard plates 70 arranged opposite each other along the second direction. Both ends of all the first cleaning brushes 21 are rotatably connected to the side guard plates 70. A pulley 211 is sleeved on the same end of all the first cleaning brushes 21. All the pulleys 211 are connected by a transmission belt 212. One of the first cleaning brushes 21 is connected to a drive motor 213. A spray pipe 71 is also provided on the side guard plate 70. The spray pipe 71 is used to communicate with a water source. A plurality of spray heads 72 are arranged along the second direction on the spray pipe 71.

[0037] Specifically, the lower ends of the two side guard plates 70 are mounted on the workbench 10, and the two side guard plates 70 are vertically arranged. The side guard plates 70 support all the first cleaning brushes 21, and both ends of all the first cleaning brushes 21 are rotatably connected to the two side guard plates 70. Pulleys 211 are installed at the portions of the first cleaning brushes 21 that penetrate the side guard plates 70, and all the pulleys 211 are connected by a drive belt 212. A drive motor 213 is installed on the leftmost or rightmost pulley 211, thereby enabling all the first cleaning brushes 21 to rotate in the same direction, allowing the fruits and vegetables above the first cleaning brushes 21 to be transported in the same direction. A spray pipe 71 is mounted on the two side guard plates 70, and multiple spray heads 72 are installed on the spray pipe 71. The spray heads 72 disperse the cleaning water to a certain extent, increasing the coverage area of ​​the cleaning water. The spray pipe 71 can be directly connected to municipal pipelines or to a container storing cleaning water.

[0038] Example 3

[0039] As an optional implementation, this embodiment provides a specific structure of a first cleaning brush 21, including: the first cleaning brush 21 includes a cylinder 22 and a brush body 23. The outer wall of the cylinder 22 has a plurality of grooves arranged circumferentially thereon. All the grooves are arranged along the axial direction of the cylinder 22. The portion of the cylinder 22 located between adjacent grooves forms a protrusion. The grooves and the protrusions are smoothly connected. The brush body 23 is disposed on the outer wall of the cylinder 22. The brush body 23 includes a plurality of bristles. The first end of the bristles is connected to the cylinder 22, and the second end is a free end. The second end of all the bristles is equidistant from the outer wall of the cylinder 22. The groove or protrusion of one of the adjacent cylinders 22 is aligned with the protrusion or groove of the other cylinder 22, and a gap is formed between the adjacent cylinders 22.

[0040] Specifically, the brush body 23 includes several bristles, which can be made of rubber or fabric. The bristles themselves have a certain degree of hardness, allowing them to contact the surface of fruits and vegetables and apply sufficient external force to remove impurities from the surface. This also allows the bristles to bend, ensuring flexible contact between the bristles and the surface of the fruits, vegetables, and eggs, thus preventing damage. The bristles can be directly attached to the outer wall of the cylinder 22 by adhesive bonding.

[0041] Optionally, the brush body 23 also includes an installation layer, which is a cylindrical structure adapted to the shape of the outer wall of the cylinder 22. The installation layer can undergo elastic deformation, so that the inner diameter of the installation layer can be increased, so that the installation layer can be installed on the cylinder 22 along one end of the cylinder 22 in the axial direction. Several bristles are arranged on the outer wall of the installation layer.

[0042] Specifically, the brush body 23 may also include an mounting layer (not shown in the figure), on which all the bristles are disposed. During installation, the mounting layer adheres to the outer wall of the cylinder 22, facilitating quick installation of the brush body 23 onto the cylinder 22. The mounting layer can be a cylindrical structure with a certain degree of elasticity, with the bristles covering the outer wall of the mounting layer. During installation, the mounting layer is slipped onto the cylinder 22 from one end and moves along the other end, thereby achieving quick installation of the mounting layer onto the cylinder 22. When it is necessary to replace the brush body 23 with one of different lengths or types, quick disassembly and installation of the brush body 23 can be achieved.

[0043] Optionally, the brush body 23 also includes at least two mounting units (not shown in the figure). The at least two mounting units are made of flexible material and can be attached to the outer wall of the cylinder 22. Several bristles are arranged on the same side of the outer wall of the mounting unit. The outer wall of the cylinder 22 is provided with a receiving groove extending along the axial direction of the cylinder 22. The two ends of the mounting unit along the circumferential direction are respectively located in the receiving groove. A pressure rod is provided in the receiving groove, which is used to press the part of the mounting unit located in the receiving groove.

[0044] Specifically, the mounting units are made of flexible material to ensure they can adhere to the outer wall of the cylinder 22 along its surface. All mounting units work together to cover the outer wall of the cylinder 22. It should be noted that the number of receiving slots corresponds to the number of mounting units. For example, if there are two mounting units, there are also two receiving slots, with the two ends of each mounting unit located within one slot. Similarly, if there are three mounting units, there are also three receiving slots. The three mounting units are sequentially mounted onto the cylinder 22 in a clockwise or counterclockwise direction, with each slot accommodating the two ends of an adjacent mounting unit. During installation, the two ends of the mounting unit are first placed into the receiving slots, and then pressure rods are installed from the outside in. The pressure rods compress the mounting units, thus pressing the portion of the mounting unit located within the receiving slot. By removing the pressure rod from the receiving groove, the mounting unit can be disassembled, allowing for quick disassembly and installation of individual mounting units. This also enables rapid replacement of damaged units. Similarly, brushes of different lengths or materials can be installed on the same roller according to actual usage requirements. It should be noted that the two ends of the pressure rod can be fixed to the two ends of the cylinder 22 using bolt assemblies 13 or similar methods to ensure that the pressure rod will not accidentally retract from the receiving groove during cylinder 22 rotation.

[0045] Optionally, the side wall of the cylinder 22 is also provided with multiple through mounting holes, and the mounting unit is provided with a limiting member. The size of the limiting member is larger than the inner diameter of the mounting hole, and the limiting member can undergo elastic deformation so that the limiting member is at least partially located in the mounting hole.

[0046] Specifically, by installing the limiting component into the mounting hole, the mounting unit is fixed in place, allowing it to fit snugly against the cylinder 22, thus improving the integrity of the mounting unit and the cylinder 22 and reducing the risk of the mounting unit moving arbitrarily.

[0047] By using at least two cylinders 22 side by side, the cleaning path for fruits, vegetables, poultry, and eggs is increased, improving the cleaning effect. A gap is formed between adjacent cylinders 22, allowing debris falling from the surface of the fruits, vegetables, poultry, and eggs to fall through the gap and into the lower part of the cylinder 22. By aligning the grooves and protrusions, the number of bristles can be increased within a given width. The bristles are distributed on the protrusions and grooves, allowing them to contact the surface of the fruits, vegetables, poultry, and eggs at multiple different angles. For example, if the surface of the fruits and vegetables has pits or narrow crevices, the bristles at different positions increase the probability of entering the grooves or narrow crevices, improving the surface cleaning effect.

[0048] Example 4

[0049] As an optional implementation, this embodiment provides a specific installation structure for the second cleaning brush 24, including: two side guard plates 70 are also provided with a second cleaning brush 24 located above the first cleaning brush 21, the two side guard plates 70 are provided with a through groove 73, a portion of the second cleaning brush 24 passes through the groove 73 and can move up and down along the groove 73, the side guard plates 70 are provided with a positioning plate 74 located above the second cleaning brush 24, and a buffer spring 75 is provided between the positioning plate 74 and the second cleaning brush 24.

[0050] In this embodiment, by setting a second cleaning brush 24 above multiple first cleaning brushes 21, when fruits and vegetables move to the position between the first cleaning brushes 21 and the second cleaning brush, the fruits and vegetables continue to move along the conveying direction. The fruits and vegetables can lift the second cleaning brush 24 and move upward, so that the first cleaning brushes 21 and the second cleaning brush 24 can cooperate to increase the force of the first cleaning brushes 21 and the second cleaning brush 24 on the fruits and vegetables, thereby improving the scrubbing effect of the first cleaning brushes 21 and the second cleaning brush 24 on the fruits and vegetables. Under the action of its own weight and the buffer spring 75, the second cleaning brush 24 always has a downward tendency. After the fruits and vegetables move from the second cleaning brush 24 and one side to the other side, the second cleaning brush 24 can automatically move downward to the initial state to scrub the next fruits and vegetables. Since the upward movement distance of the second cleaning brush 24 is determined by the size of the fruits and vegetables, it can automatically adapt to fruits and vegetables of different diameters, ensuring that the second cleaning brush 24 can clean fruits and vegetables of different sizes. Compared with the fixed position of the second cleaning brush 24, a channel for fruits and vegetables to pass through is reserved between the first cleaning brush 21 and the second cleaning brush 24, which can effectively avoid the situation that smaller fruits and vegetables cannot be cleaned.

[0051] Optionally, the workbench 10 is provided with a slag discharge port in the part located in the cleaning area, and a collection hood 80 is provided below the slag discharge port. The cross-sectional area of ​​the collection hood 80 gradually decreases from top to bottom, and a collection box 81 is detachably provided at the lower end of the collection hood 80.

[0052] Specifically, a slag discharge port is provided on the workbench 10 so that after the washing assembly 20 scrubs the surface of fruits and vegetables to remove dirt and other debris, the debris can directly enter the slag discharge port or be carried by the washing water. A collection hood 80, funnel-shaped, is provided below the slag discharge port. A collection box 81 is located at the lower end of the collection hood 80. The collection hood 80 guides the debris into the collection box 81, facilitating its centralized transfer to the debris treatment area. The collection box 81 is detachably mounted from the collection hood 80 and can be equipped with a guide and limiting structure. For example, a limiting flange is provided on each side of the lower end of the collection hood 80, and a limiting groove is provided on the inner wall of the collection box 81 to mate with the limiting flange. The limiting groove extends through the collection box 81 along its extension direction. During installation, the limiting flange enters the limiting flange from one side of the extending direction of the limiting groove.

[0053] Optionally, the conveying component includes a rotatable shaft 91, the outer wall of which is provided with helical blades 92 along its axial direction.

[0054] Specifically, the rotating shaft 91 and the spiral blade are one type of conveying component structure. A shell structure can also be located around the spiral blade 92. The shell structure is located outside the two rotating shafts 91 to ensure that the fruits and vegetables do not move to the outside of the two spiral blades 92 and detach from the spiral blades 92, thus preventing the fruits and vegetables from being conveyed normally.

[0055] Optionally, the conveyor includes two rotatable positioning shafts 41, one of which is connected to a servo motor. The two positioning shafts 41 are connected to each other via a conveyor belt 40, and a screening channel 31 is formed between one side of the conveyor belt 40 and the worktable 10.

[0056] Specifically, the conveyor belt 40 is another structural form of the conveying component, such as... Figure 2 As shown, two conveyor belts 40 are arranged in the second direction, parallel to each other, with their conveying surfaces facing each other. A positioning shaft 41 is located at each end of the same conveyor belt 40. The lower end of the positioning shaft 41 is connected to the worktable 10, and the upper end of the positioning shaft 41 is suspended. Bearings can also be fitted onto the positioning shaft 41, and the conveyor belt 40 is fitted onto the bearings. A screening channel 31 is formed between the working surface of the conveyor belt 40 and the guide surfaces on both sides of the screening component 30. The conveyor belts 40 can drive the movement of fruits and vegetables.

[0057] Optionally, the upper end of the collection frame 50 is an open structure, and the collection frame 50 is connected to the screening channel 31. The upper and lower ends of the collection frame 50 are provided with a set of slots 53 for cooperating with the partition 51. Multiple sets of slots 53 are arranged in the collection frame 50 along the first direction. A movable plate 54 is provided on one side wall of the collection frame 50. The lower end of the movable plate 54 is hinged to the lower end of the collection frame 50, and the upper end of the movable plate 54 can be detachably connected to the upper end of the collection frame 50.

[0058] Specifically, the collection frame 50 includes a base plate, three side plates located on the left, right, and rear sides respectively, and open structures on the front and top sides. The opening on the top side is used to receive fruits and vegetables falling from the screening channel 31, and the opening on the front side is used to remove fruits and vegetables from the screening frame. By setting multiple sets of slots 53, it is easy to place the partition 51 into different slots 53 positions, thereby adjusting the length of the collection area 52 in the first direction. By setting a movable plate 54, when it is not necessary to transfer the fruits and vegetables in the collection frame 50, the movable plate 54 can block the opening on the front side, and at this time the movable plate 54 also acts as a limit for the partition 51; when it is necessary to transfer the fruits and vegetables in the collection frame 50, or when it is necessary to adjust the position of the partition 51, the movable plate 54 can be opened.

[0059] Optionally, the lower end of the worktable 10 is provided with at least three support leg units, each including a first support leg 11 and a second support leg 12. The upper end of the first support leg 11 is hinged to the worktable 10, the upper end of the second support leg 12 has a receiving groove, the lower end of the first support leg 11 is located in the receiving groove, the lower end of the first support leg 11 has a through first hole, and the upper end of the second support leg 12 has a plurality of second through holes arranged axially. The first through hole can optionally be aligned with one of the second through holes, and the alignment of the first through hole and the second through hole is connected by a bolt assembly 13.

[0060] Specifically, by setting multiple support leg units, the tilt of the working surface of the workbench 10 can be adjusted by the support unit. The first through hole on the first support leg 11 can be aligned with one of the second through holes on the second support leg 12, thereby realizing the adjustment of the overall height formed by the first support leg 11 and the second support leg 12. The first support leg 11 and the second support leg 12 can be fixed as a whole by the bolt assembly 13.

[0061] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
