Automatic circulating sorting device for potatoes

Abstract

According to the automatic circulating sorting device for the potatoes, the minitubers can be conveyed to the high position through the elevator and discharged out of the discharging port, and the discharged minitubers can be conveyed into the screen of the screening box through the dip angle conveying belt. The vibration motor is started to drive the screening box and the screen to vibrate, and the potato minitubers can sequentially pass through the whole screen and move towards the direction of the material returning opening of the elevator. In the process, the potato minitubers conforming to the size of the screen can fall to the bottom plate of the screening box, and fall onto the conveying belt through the discharging opening under the vibration effect so as to be conveyed to the designated position. And the rest of miniature potatoes can continue to enter the elevator through the material returning opening, and the process is repeated. By the adoption of the structural design, miniature potatoes can be sorted in a circulating and reciprocating mode, and therefore the sorting precision is improved.

Description

Technical Field

[0001] This application relates to the field of potato sorting technology, and more specifically, to an automatic circulating potato sorting device. Background Technology

[0002] Miniature potatoes refer to small, virus-free potatoes produced under isolated conditions such as greenhouses or net houses, using substrates or substrate-free methods (hydroponics, aeroponics). Potato seed potatoes are classified into original seed potatoes, seed potatoes, and qualified seed potatoes, with miniature potatoes belonging to the first level of original seed potatoes and being the highest grade of seed potatoes.

[0003] In related technologies, in order to ensure uniform emergence of mini-tubers and facilitate field management, mini-tubers must be graded by size before planting to screen the mini-tubers of potatoes through sorting.

[0004] Traditionally, vibrating sorting machines are used to sort potato microtubers through sieves with different mesh sizes. However, since potato microtubers are sorted in batches, it is difficult to accurately grade potato microtubers that meet the size requirements in a single sorting process, thus affecting subsequent planting operations. Utility Model Content

[0005] In view of this, this application provides an automatic circulating potato sorting device to solve the problem in the related art that it is difficult to accurately sort potato micro-tubers that meet the size requirements by means of vibration screening.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] An automatic potato sorting and recycling device includes:

[0008] frame;

[0009] A screening box is mounted on the frame via the damping spring. A vibration motor is fixedly mounted at the bottom of the screening box, and a discharge port that cooperates with the bottom plate of the screening box is provided on one side of the discharge end.

[0010] A screen is laid inside the screening box, the screen is located at the middle position in the height direction of the screening box, and the screen is located above the inclined surface;

[0011] A conveyor belt is disposed below the screening box and the discharge port, and the transport direction of the conveyor belt is opposite to the transport direction of the screening box.

[0012] The elevator is located beside the frame. The bottom of the elevator is provided with a feed inlet, the top of the elevator is provided with a discharge outlet, and a return outlet is provided near the middle of its height direction. The return outlet is connected to the discharge end of the screen.

[0013] An inclined conveyor belt is installed at the discharge port of the elevator. The inclined conveyor belt is used to transport the material in the elevator to the interior of the screening box and is located on the feed end side of the screen.

[0014] In some possible implementations, a conveyor plate is provided at the return port of the elevator, which overlaps the screen.

[0015] In some possible implementations, the return port of the elevator is connected to the conveyor plate by a hinged connection.

[0016] In some possible implementations, the bottom plate of the screening box has an inclined surface on its upper surface, and the thickness of the inclined surface on the side near the feed end of the screening box is less than the thickness on the opposite side.

[0017] In some possible implementations, the screen is laid at an angle inside the screening box, and the angle of the screen is consistent with the angle of the inclined surface.

[0018] In some possible implementations, a barrier is provided around the conveyor plate to prevent material from falling off.

[0019] The automatic potato sorting device provided in this application has at least the following beneficial effects:

[0020] In the automatic potato sorting device provided in this application embodiment, a hoist transports mini-potatoes to a high position and discharges them from the outlet. The discharged mini-potatoes are then conveyed to the screen of the screening box via an inclined conveyor belt. A vibrating motor is activated, causing the screening box and screen to vibrate. The mini-potatoes pass through the entire screen sequentially and move towards the return port of the hoist. During this process, mini-potatoes that fit the screen size fall to the bottom plate of the screening box and, under vibration, fall through the discharge port onto the conveyor belt for transport to a designated location. The remaining mini-potatoes return to the hoist through the return port, repeating the above process. This structural design allows for the continuous sorting of mini-potatoes, thereby improving sorting accuracy. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-3 As shown in the embodiment of this application, the automatic potato circulating sorting device includes a frame 100, a screening box 200, a screen 300, a conveyor belt 400, an elevator 500, and an inclined conveyor belt. The frame 100 serves as the supporting structure for the sorting device. The screening box 200 is mounted on the frame 100 via damping springs 210, and a vibration motor 220 is fixedly mounted at the bottom of the screening box 200. The screen 300 is laid inside the screening box 200, and is located at the center of the screening box 200 in the depth direction. Furthermore, a discharge port 230 is provided on one side of the discharge end of the screening box 200, allowing potato micro-tubers that have passed through the screen 300 to move to a designated position via the discharge port 230.

[0029] In this embodiment, the frame 100, screening box 200, vibration damping spring 210, vibration damping motor, and screen 300 constitute a vibrating screening machine. By pouring potato microtubers onto the screen 300 and starting the vibration motor 220, the potato microtubers can be vibrated and sorted.

[0030] A vibrating screen is equipped with an elevator 500 on its side, which transports potato microtubers from bottom to top. Specifically, the elevator 500 has a feed inlet 510 at its bottom and a discharge outlet 520 at its top. Furthermore, a return outlet 530 is located near the wall of the screen 300, and this return outlet 530 is connected to the discharge end of the screen 300.

[0031] Continue as Figures 1-3 As shown, an inclined conveyor belt 600 is also installed at the discharge port 520 at the top of the elevator 500, with the other end of the inclined conveyor belt 600 located above the feed end of the screen 300. In actual use, the potato mini-tubers to be sorted can be fed into the elevator 500 through the feed port 510, and then the elevator 500 will transport the potato mini-tubers to the top. After that, the inclined conveyor belt 600 will feed the potato mini-tubers onto the screen 300, and the potato mini-tubers will be screened by a vibrating screener.

[0032] In addition, a conveyor belt 400 is installed at the bottom of the screening box 200, which is located at the discharge port 230 of the vibrating screening machine. Therefore, potato microtubers that pass through the screen 300 will enter the conveyor belt 400 through the discharge port 230 and be transported by the conveyor belt 400 to a designated location for collection and subsequent processing.

[0033] In the automatic potato sorting device provided in this application embodiment, the elevator 500 transports potato microtubers to a high position and discharges them through the outlet 520. The discharged potato microtubers are then conveyed to the screen 300 of the screening box 200 via the inclined conveyor belt 600. The vibration motor 220 is started to vibrate the screening box 200 and the screen 300, causing the potato microtubers to pass through the entire screen 300 sequentially and move towards the return port 530 of the elevator 500. During this process, potato microtubers that meet the size requirements of the screen 300 fall to the bottom plate of the screening box 200 and, under the action of vibration, fall through the drop port 230 onto the conveyor belt 400 to be conveyed to a designated position. The remaining potato microtubers return to the elevator 500 through the return port 530, repeating the above process. This structural design allows for the continuous sorting of potato microtubers, thereby improving sorting accuracy.

[0034] In some embodiments, a conveyor plate 700 is hinged at the return port 530 located in the middle of the elevator 500, and the other end of the conveyor plate 700 overlaps the screen 300 of the vibrating screen. Therefore, potato microtubers passing through the screen 300 will enter the elevator 500 through the return port 530 under vibration and undergo re-sorting through the aforementioned steps. Preferably, a baffle 800 is provided around the conveyor plate 700 to prevent the potato microtubers from falling outside under vibration.

[0035] In some embodiments, the upper surface of the bottom plate of the screening box 200 is an inclined surface 900. The thickness of the inclined surface 900 on the side near the feed end of the screening box 200 is less than the thickness on the opposite side. The inclined surface 900 is located below the screen 300. The inclined surface 900 slows down the movement of potato microtubers under vibration, thereby preventing the problem of clogging the feed inlet 230.

[0036] Preferably, the screen 300 is arranged at an angle within the screening box 200, and the angle of the screen 300 is consistent with the angle of the inclined surface 900. The inclined screen 300 can slow down the speed at which potato microtubers pass through the screen 300, thereby improving the screening accuracy of the screen 300 for potato microtubers.
