Description

Technical Field

[0001] This utility model relates to the field of potato production technology, specifically to a high-efficiency soil screening device for potato production and processing. Background Technology

[0002] When freshly harvested potatoes undergo further processing, they need to be de-mudized to remove the soil adhering to them. If water washing is used, the potatoes are not easy to preserve. Therefore, soil removal is usually done using equipment such as brushes or vibrating screens. However, cleaning with brushes is inefficient, and using vibrating screens does not clean thoroughly, thus affecting production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency potato soil screening device for production and processing, which solves the problems of low efficiency and incomplete soil screening in existing equipment mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency soil screening device for potato production and processing, comprising a roller conveyor and a soil screening mechanism mounted on the roller conveyor. The roller conveyor includes a frame, a drive mechanism mounted on the frame, and a conveying roller assembly mounted on the frame and driven by the drive mechanism. The soil screening mechanism is mounted on the frame and used in conjunction with the conveying roller assembly, and the conveying roller assembly is driven by the soil screening mechanism.

[0005] Furthermore, the conveying roller assembly includes a drive roller and a plurality of driven rollers rotatably connected to the frame; each of the drive roller and the plurality of driven rollers is provided with a brush.

[0006] Furthermore, the drive mechanism includes a motor mounted on the frame, and sprockets mounted on one end of the drive roller and a plurality of driven rollers and located outside the frame; the output shaft of the motor is connected to the sprockets located on the drive roller, and the plurality of sprockets are connected by chain drive.

[0007] Furthermore, the soil screening mechanism includes a support mounted on the frame and close to the discharge port of the roller conveyor, and a rotating screen roller rotatably connected to the support; a drive gear located outside the frame is provided on the other end of the driven roller, and a driven gear is provided on the end of the rotating screen roller that is in the same direction as the drive gear, and the drive gear meshes with the driven gear.

[0008] Furthermore, the roller conveyor is equipped with a vibrating motor at the feed inlet end, and the bottom of the frame is connected to a base by springs.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model uses a vibrating motor to drive a roller conveyor to vibrate, and combines the rotating brushes on the surface of the conveyor rollers to wash the potatoes, thus achieving initial and efficient soil removal. Furthermore, through the meshing transmission of the active and driven gears, the rotating screen rollers and the conveyor rollers rotate in opposite directions, forming a secondary deep cleaning effect. Compared with the traditional single brush or vibrating screen method, this improves soil screening efficiency and reduces soil residue.

[0011] 2. The elastic support design of the spring between the frame and the base of this utility model can amplify the vibration amplitude, avoid rigid impact damage to the potato skin, and reduce damage during soil screening. The whole machine adopts a sprocket and chain synchronous drive conveyor roller group, combined with gear linkage soil screening mechanism, to realize single motor drive of multiple mechanisms to work together, reduce energy consumption, and have the characteristics of high-efficiency soil screening and low power consumption.

[0017] Please see Figures 1 to 3 A high-efficiency soil screening device for potato production and processing consists of a roller conveyor and a soil screening mechanism mounted on the roller conveyor. The conveying surface of the roller conveyor is inclined at the discharge end. Figure 3 As shown, a roller conveyor and a soil screening mechanism are used together to remove soil adhering to potatoes, thus realizing the soil screening operation before potato recycling.

[0018] The roller conveyor includes a frame 1, a drive mechanism, and a conveying roller assembly. The frame 1 has side guards on both sides to prevent potatoes from falling off. A vibrating motor 11 is installed at the feed inlet end of the roller conveyor. The installation position and model of the vibrating motor 11 should be compatible with the roller conveyor. When the vibrating motor 11 drives the roller conveyor to vibrate, it should not affect the conveying effect of the roller conveyor. The bottom of the frame 1 has a base 13 connected by springs 12, which can be metal helical springs, rubber springs, etc. The conveying roller assembly consists of a drive roller 2 and multiple driven rollers 3, all rotatably connected to the frame 1 via bearings and other components. Specifically, as shown... Figure 1As shown, soft brushes are provided on the driving roller 2 and multiple driven rollers 3.

[0019] The drive mechanism consists of a motor 10, sprockets 4, and a chain 5. The motor 10 is mounted on the frame 1 via a motor mount. The motor 10 is self-locking and can be an electromagnetic brake motor, a permanent magnet brake motor, or a worm gear reducer motor, etc. Multiple sprockets 4 are respectively connected to the end of the drive roller 2 and multiple driven rollers 3 extending to the outside of the frame 1. The chain 5 is used to connect multiple sprockets 4 so that when the motor 10 drives the sprocket 4 located on the drive roller 2 to rotate, it drives the sprockets 4 located on the multiple driven rollers 3 to rotate.

[0020] The soil screening mechanism consists of a support 6 and rotating screen rollers 7. The support 6 is located on both sides of the frame 1 near the discharge port of the roller conveyor. There are multiple rotating screen rollers 7, all of which are rotatably connected between two supports 6 through bearings and other components. The rotating screen rollers 7 consist of a drive shaft and a brush plate made of nylon filaments, sponge, etc., mounted on the drive shaft. A drive gear 8 is provided on the other end of the driven roller 3 extending to the outside of the frame 1. A driven gear 9 is provided on the end of the drive shaft that is in the same direction as the drive gear 8. By meshing the drive gear 8 and the driven gear 9, the rotating screen rollers 7 are driven to rotate together and in the opposite direction when the driven roller 3 rotates, so as to clean the potatoes again and improve the soil screening efficiency.

[0021] The working principle of this utility model is as follows: When screening potatoes for soil, the motor 10 and the vibrating motor 11 are started, and the potatoes are placed at the feed inlet of the roller conveyor. The vibrating motor 11 drives the roller conveyor to vibrate and shake off the soil from the potatoes. At the same time, the soft brushes on the active roller 2 and multiple driven rollers 3 scrape off the soil from the potatoes. While scraping off the soil, the active roller 2 and multiple driven rollers 3 drive the potatoes to move towards the discharge outlet of the roller conveyor. When the potatoes move to the position where the soil screening mechanism is located, the soft brushes on the driven rollers 3 and the brush plates on the rotating screen rollers 7 move in opposite directions synchronously to perform a secondary cleaning of the soil on the potatoes.
