Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sweet potato processing technology, and in particular relates to a sweet potato harvester separation device. Background Technology
[0002] After harvesting sweet potatoes, they often carry soil with them. Traditional manual washing of sweet potatoes is inefficient, labor-intensive, and water-washing consumes a lot of water and cannot effectively remove deeply attached soil. The surface of the washed sweet potatoes is left with moisture, and if they are not dried in time, they are very prone to mold growth and rot during storage or transportation. Therefore, a sweet potato harvester separation device has been proposed. Utility Model Content
[0003] The purpose of this utility model is to provide a sweet potato harvester separation device to solve the problems mentioned in the background art.
[0004] A sweet potato harvester separation device includes a fixed plate, a conveyor frame fixedly connected to the fixed plate, multiple electric rollers mounted on the conveyor frame, a support frame fixedly connected to the conveyor frame, multiple cleaning brushes rotatably connected to the support frame, two fixed rods fixedly connected to the fixed plate, a first reinforcing frame fixedly connected to the fixed plate, a first electric push rod fixedly mounted on the first reinforcing frame, a first sliding rod connected to the telescopic rod of the first electric push rod, a material carrier slidably connected between the two fixed rods, the material carrier being connected to the first sliding rod, a filter screen plate slidably connected inside the material carrier, multiple second reinforcing frames fixedly connected to the material carrier, second electric push rods fixedly mounted on the second reinforcing frames, second sliding rods connected to the telescopic rods of the second electric push rods, the second sliding rods slidably connected to the material carrier, and the second sliding rods being connected to the filter screen plate, two support frames fixedly connected to the fixed plate, a water pump fixedly mounted on the support frames, a first water pipe connected to the water pump, a second water pipe connected to the water pump, and two drying fans fixedly mounted on the fixed plate.
[0005] Furthermore, a drain pipe is fixedly connected to the material receiving vehicle, and an electric valve is installed on the drain pipe.
[0006] Furthermore, the first water pipe is made of a telescopic pipe.
[0007] The beneficial effects of this utility model are:
[0008] 1. This utility model realizes the automated continuous conveying and preliminary cleaning of sweet potatoes through electric rotating rollers and cleaning brushes, which greatly reduces the manual brushing process. It adopts a centralized soaking and cleaning method, which uses water flow to dissolve and remove deep soil. Compared with running water rinsing, it makes more efficient use of water resources and can handle the attached soil that is difficult to remove with brushes.
[0009] 2. This utility model uses a drying fan to force ventilation and drying, which significantly shortens the time when moisture remains on the surface of sweet potatoes, effectively inhibits mold and rot caused by dampness, improves the storage stability and product quality of cleaned sweet potatoes, and solves the problem of easy spoilage if not dried in time after traditional washing.

Detailed Implementation
[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0018] like Figures 1 to 6The sweet potato harvester separation device of this utility model includes a fixed plate 1, a conveyor frame 2 fixedly connected to the fixed plate 1, multiple electric rollers 3 mounted on the conveyor frame 2 for transporting sweet potatoes, a support frame 4 fixedly connected to the conveyor frame 2, multiple cleaning brushes 5 rotatably connected to the support frame 4 for cleaning soil from the sweet potatoes, two fixed rods 6 fixedly connected to the fixed plate 1, a first reinforcing frame 7 fixedly connected to the fixed plate 1, a first electric push rod 8 fixedly mounted on the first reinforcing frame 7, a first sliding rod 9 connected to the telescopic rod of the first electric push rod 8, and a material carrier 10 slidably connected between the two fixed rods 6. A slide rod 9 is connected to a filter screen plate 11 that is slidably connected inside the material carrier 10. Multiple second reinforcing frames 12 are fixedly connected to the material carrier 10. A second electric push rod 13 is fixedly installed on the second reinforcing frame 12. A second slide rod 14 is connected to the telescopic rod of the second electric push rod 13. The second slide rod 14 is slidably connected to the material carrier 10 and connected to the filter screen plate 11. Two support frames 15 are fixedly connected to the fixed plate 1. A water pump 16 is fixedly installed on the support frame 15. A first water pipe 17 is connected to the water pump 16. A second water pipe 18 is connected to the water pump 16. Two drying fans 19 are fixedly installed on the fixed plate 1. The drying fans 19 are used to speed up the drying of sweet potatoes.
[0019] A drain pipe 20 is fixedly connected to the material carrier 10, and an electric valve 21 is installed on the drain pipe 20.
[0020] The first water pipe, number 17, is made of a telescopic pipe.
[0021] The working principle of this utility model is as follows: After the sweet potato is placed on the electric roller, the electric roller will transport the sweet potato. During the transportation process, the sweet potato will touch the cleaning brush, thereby driving the cleaning brush to rotate. The cleaning brush will scrape off the dirt on the surface of the sweet potato, thus completing the initial cleaning work. The cleaned sweet potato will fall into the receiving car. When there are a certain number of sweet potatoes in the receiving car, the electric roller will stop working. Then, after connecting the first water pipe to the water tank, the water pump is controlled to draw water from the water tank, so that the water passes through the first water pipe and the second... The water flows into the material carrier through the second water pipe, soaking out the residual soil on the surface of the sweet potatoes. Then, the first electric push rod moves the first slide rod and the material carrier slowly to the designated position. Next, the electric valve opens the drain pipe, and the wastewater containing soil is discharged through the drain pipe. Then, the second electric push rod moves the second slide rod and the filter plate to the designated height. The filter plate will transport the sweet potatoes upwards. Then, the air blown by the drying fan will accelerate the drying speed of the sweet potatoes and prevent them from rotting due to moisture. After the sweet potatoes are dried, they can be stored.
[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
