DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The core of the present utility model is to provide a sweet potato sorting equipment, which can effectively sort the size of sweet potatoes and keep the sorting device clean.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0026] In a specific embodiment, as Figures 1 to 4 shown, it includes a conveying table 1. On the top surface of the conveying table 1, there is a conveyor belt 2 for conveying sweet potatoes. On both sides of the conveying table 1, there are fixedly connected support plates 3. At the top of the support plates 3, there is a fixedly connected mounting plate 4. At the bottom of the mounting plate 4, there are fixedly connected a material guiding component and a cleaning component. The material guiding component is used to change the sweet potatoes placed horizontally on the conveyor belt 2 into a vertical state. At one end of the conveyor belt 2, there is a sorting box 5. Inside the sorting box 5, there is a sorting component 6. The sorting component 6 includes two conical rollers 601 rotatably connected in the inner cavity of the sorting box 5. The two conical rollers 601 are parallel and inclined downward. Inside the sorting box 5, there is a driving unit connected to one end of the two conical rollers 601. The driving unit is used to drive the two conical rollers 601 to rotate; directly above the two conical rollers 601, there is a guiding plate 7. The guiding plate 7 is inclined and one end is located between the two conical rollers 601. The other end of the guiding plate 7 is connected to the material guiding component.

[0027] By setting the material guiding component, the sweet potatoes put into the feeding end of the conveyor belt 2 are guided into a vertical arrangement, and the vertically arranged sweet potatoes are conveyed to between the two conical rollers 601 of the sorting component 6 through the guiding plate 7. Under the action of the driving unit and the gravity of the sweet potatoes, the sweet potatoes move from one end of the two conical rollers 601 to the other end, so as to effectively sort the sizes of the sweet potatoes and prevent the slender sweet potatoes from lying across between the two conical rollers 601, thus making it impossible to sort them. In addition, through the cleaning component, the sweet potatoes on the conveyor belt 2 can be cleaned before sorting, so as to keep the sorting device clean.

[0028] In a specific embodiment, the material guiding component includes two baffle plates 8. The two baffle plates 8 are arranged in parallel and fixedly connected to the bottom surface of the mounting plate 4. The baffle plates 8 are arranged along the length direction of the conveyor belt 2. Fixedly connected to the end faces of one end of the two baffle plates 8 away from the sorting box 5 are guide plates 9. The bottom surfaces of the other ends of the two guide plates 9 are fixedly connected to the top surfaces of both sides of the conveying table 1. There is a clearance between the bottom surfaces of the baffle plates 8 and the guide plates 9 and the top surface of the conveyor belt 2, which can avoid friction between the baffle plates 8 and the guide plates 9 and the conveyor belt 2. The bottom surface of the other end of the baffle plate 8 is fixedly connected to the material guiding plate 7. The distance between the two baffle plates 8 is determined according to the diameter of the sweet potatoes, so that the channel formed between the two baffle plates 8 can ensure that sweet potatoes with a general size diameter can pass vertically smoothly, while the horizontally placed sweet potatoes cannot pass through.

[0029] Through the arrangement of the two guide plates 9, the sweet potatoes entering the conveyor belt 2 can be guided, so that the sweet potatoes can enter vertically between the two baffle plates 8, and the conveyor belt 2 transports the sweet potatoes along the baffle plates 8 to the material guiding plate 7.

[0030] Specifically, a guide wheel 10 is rotatably connected to the connection between the bottom of the baffle plate 8 and the guide plate 9. When the sweet potatoes are turning, it can reduce the friction between the sweet potatoes and the guide plate 9, making the transportation of the sweet potatoes smoother.

[0031] Specifically, the cleaning component includes a diversion pipe 11. The diversion pipe 11 is externally connected to a water supply device (not shown in the drawings). The diversion pipe 11 is fixedly connected to the bottom surface of the baffle plate 8 and is located between the two baffle plates 8. A number of spray heads 12 are fixedly connected to the diversion pipe 11 at intervals, and the spray heads 12 face the conveyor belt 2. By supplying water to the spray heads 12 through the diversion pipe 11, the spray heads 12 can spray and clean the sweet potatoes between the baffle plates 8.

[0032] Specifically, the conveyor belt 2 uses a stainless steel mesh conveyor belt, which can make the sewage generated when the cleaning component cleans the sweet potatoes flow downward through the stainless steel mesh. A water collecting tank 13 is fixedly connected to the bottom surface of the conveying table 1, which can collect the sewage flowing down from the stainless steel mesh conveyor belt.

[0033] In a specific embodiment, at both ends of the inner cavity of the sorting box 5, inclined plates 602 are fixedly connected. The two ends of the two conical rollers 601 are respectively rotatably connected to the inclined plates 602. The driving unit includes a motor 603. The motor 603 is fixedly connected to one side surface of the inclined plate 602. Fixedly connected to one end of each of the two conical rollers 601 is a gear 604, and the two gears 604 are meshed with each other. The motor 603 is fixedly connected to one end of one of the conical rollers 601. A number of collecting boxes 605 arranged along the length direction of the conical rollers 601 are detachably connected to the bottom surface of the sorting box 5.

[0034] By the rotation of the motor 603, the conical roller 601 connected thereto is driven to rotate, thereby driving the gear 604 connected to the conical roller 601 to rotate, and further driving another gear 604 and another conical roller 601 to rotate. It should be noted that the rotation direction of the two conical rollers 601 is controlled by the rotation direction or installation position of the motor 603, so that the sweet potatoes between the two conical rollers 601 can be simultaneously subjected to an upward acting force, preventing the sweet potatoes from getting stuck between the two conical rollers 601. Through the collection box 605, the sorted sweet potatoes can be collected.

[0035] Specifically, the bottom surface of the collection box 605 is inclined and the top is open. A plurality of discharge ports 606 corresponding to the collection box 605 one by one are opened on the side wall of the sorting box 5, and the discharge ports 606 are respectively communicated with the lower side of the bottom surface of the corresponding collection box 605.

[0036] The sorted sweet potatoes are collected by the collection box 605, and due to the inclined arrangement of the bottom surface of the collection box 605, the sweet potatoes roll along the slope of the bottom surface of the collection box 605 towards the discharge port 606 under the action of gravity.

[0037] Working principle of the present utility model: When the sweet potato sorting device of the present utility model is in use, the sweet potatoes are placed on the conveyor belt 2, and the conveyor belt 2 starts to run, transporting the sweet potatoes towards one end of the sorting component 6. Under the action of the guide plate 9 and the guide wheel 10 of the guiding component, the sweet potatoes enter between the two baffles 8 under the guidance of the guide plate 9, turning the horizontally placed sweet potatoes into a vertical arrangement. When the sweet potatoes pass through the cleaning component, an external water supply device supplies water to a plurality of nozzles 12 through the diversion pipe 11. The water sprayed by the nozzles 12 cleans the sweet potatoes, removing the soil and impurities on the surface of the sweet potatoes. The cleaned sewage flows downward through the mesh holes of the stainless steel mesh conveyor belt 2 and is collected by the water collection tank 13. The cleaned sweet potatoes continue to be transported forward by the conveyor belt 2 until they reach the guide plate 7. The guide plate 7 transports the vertically arranged sweet potatoes to between the two conical rollers 601 of the sorting component 6. The motor 603 is started to drive one of the conical rollers 601 to rotate. Since the two conical rollers 601 are meshed with each other through the gear 604, the two conical rollers 601 rotate in opposite directions simultaneously. The sweet potatoes are subjected to an upward acting force between the two conical rollers 601 and start to move from one end of the conical roller 601 to the other end. Due to the inclined arrangement of the conical roller 601, the sweet potatoes will be sorted to different positions according to their sizes during the movement. The smaller sweet potatoes will fall first, while the larger sweet potatoes will continue to move forward until they reach the next collection point. The sorted sweet potatoes fall into the corresponding collection box 605. The bottom surface of the collection box 605 is inclined, enabling the sweet potatoes to roll along the slope towards the discharge port 606, facilitating subsequent collection and processing.

[0038] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple. For related parts, reference can be made to the description in the method part.

[0039] The above-described embodiments are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
