Technical Field

[0001] The utility model relates to the technical field of walnut kernel processing, and more specifically to a vibration screening device for walnut kernel production. Background Art

[0002] Walnut is a plant of the Juglandaceae family. Walnut kernels are rich in nutrients, and contain a variety of trace elements and minerals such as calcium, phosphorus, iron, etc., as well as a variety of vitamins such as carotene and riboflavin, which are extremely beneficial to the human body. When processing walnut kernels, the walnuts need to be crushed first, and then the walnut shells and walnut kernels are sorted, and finally a screening device is used to screen the whole walnut kernels and the broken walnut kernels.

[0003] After searching, the existing patent (Announcement No.: CN217857277U) discloses a vibrating screening device for walnut kernel production. During use, the screening cover is driven to move by the cam by rotating the motor, and the elastic force of the spring is released to make the screening cover and the screening plate reciprocate along the support rod, so that the walnut kernel moves, reducing the time consumed for screening and achieving the effect of improving the screening efficiency of the vibrating screening device. However, the inventor found that the prior art has the following problems in the process of realizing the utility model: the above-mentioned screening device screens the walnut kernel in a shaking manner, and in actual operation, the surface of the walnut kernel is attached with a kernel film, and the presence of the kernel film will reduce the beauty of the walnut kernel, and it is difficult to separate the kernel film from the walnut kernel by a single shaking method, so the above-mentioned screening device is defective in terms of use effect.

[0004] In view of this, the utility model proposes a vibration screening device for walnut kernel production to solve this problem. Utility Model Content

[0008] Furthermore, a feed hopper is welded to the top of the feed pipe, and a cover is provided on the surface of the feed hopper; by providing the cover, the feed hopper can be blocked to determine the air inlet direction when the induced draft fan induces air flow.

In the process of shaking, the screening mesh plate 5 is used to realize the screening of complete walnut kernels and broken walnut kernels, and the broken walnut kernels and part of the film coating will pass through the screening mesh plate 5 and fall into the waste collection frame 6.

[0027] The screening mesh plate 5 is rotatably connected to the bottom end of the screening frame 4 , and a positioning screw 24 for locking with the screening frame 4 is provided on the surface of the screening mesh plate 5 .
