Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, and in particular to a screening device for nut processing. Background Technology

[0002] Nuts are a type of indeterminate fruit with a hard shell containing one or more seeds. Nuts are considered the essence of plants, generally rich in nutrients, containing high levels of protein, oils, minerals, and vitamins, and are widely enjoyed. The production process of nuts typically includes steps such as selection, impurity removal, roasting, cooling, screening, and packaging. Before bagging, screening devices are usually used to remove broken nuts or shells.

[0003] In the production, processing and packaging of nuts, it is generally necessary to screen the processed nuts. Existing screening devices often require a lot of manpower and resources when screening large quantities of nuts, and the screening efficiency is low. In order to overcome the shortcomings of existing technologies, we propose a screening device for nut processing. Utility Model Content

[0004] The main objective of this invention is to provide a screening device for nut processing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Side supports are mounted on both sides of the outer surfaces of the two sets of screening frames. Two sets of swaying frames are mounted on the lower outer surface of the two sets of screening frames. All four sets of swaying frames are connected to the screening machine base. Two sets of mounting bolts are mounted on the outer surfaces of each of the four sets of swaying frames, and each set of mounting bolts is connected to the screening machine base. Two sets of mounting shafts are mounted on both sides of the outer surfaces of the two sets of screening frames. Two sets of connecting rods are provided between the frames, and the two sets of connecting rods are respectively connected to the mounting shafts on the outer surfaces of the two sets of screening frames. An inner screening frame is provided inside the screening machine base, and a filter screen is provided inside the inner screening frame. A scraper plate is provided on the upper outer surface of the filter screen. A slide rail is provided on one outer surface of the inner screening frame, and a handle is provided on the outer surface of the slide rail. The handle is connected to the scraper plate. An inclined plate is provided at the front end of the filter screen, and a waste material trough is provided at the lower end of the filter screen. The waste material trough is installed inside the inner screening frame.

[0007] Preferably, the screener base has a feed inlet on the back side, a filter groove inside the feed inlet, and a discharge trough on the lower outer surface of the feed inlet, which is mounted on the upper end of the screener frame.

[0008] Preferably, a receiving frame is provided on the outer surface of the front end of the screening machine base, the receiving frame is connected to the screening frame, and a mounting platform is provided on one side of the outer surface of the screening machine base, and a vibration motor is provided on the outer surface of the mounting platform.

[0009] Preferably, the swaying frame is installed between the screening frame and the screening machine base, the screening frame and the screening machine base are detachably connected by the swaying frame, the mounting bolts are installed between the swaying frame and the screening machine base, and the swaying frame and the screening machine base are detachably connected by the mounting bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the nuts are screened by a screen frame. The screen frame can remove small nuts that do not meet packaging requirements and broken nuts. The screening effect of the device is accelerated by vibration. At the same time, both sets of screen frames are equipped with a shaking frame at the bottom. The shaking structure of the shaking frame causes the screen frame to shake due to vibration, thereby improving the screening efficiency.

[0014] 2. In this utility model, the inner screening frame can be used to screen the small nut particles that are screened out again. The filter screen separates the nuts from the mixed peels and shells, allowing the peels and shells to fall into the waste material trough for easy cleaning. The remaining nuts are collected through the filter screen for use in other processing methods. The scraper plate can scrape the residual material in the filter screen to improve the practicality of the device. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4 As shown, a nut processing screening device is used for screening nuts before packaging. In use, nuts are poured into the inlet 2 and, after initial filtration by the filter tank 3, fall into the outlet chute 4 at the top of the screening rack 7. The outlet chute 4 then loads the nuts onto the two sets of screening racks 7. The vibration motor 6 is then activated, causing the two sets of screening racks 7 to vibrate. The vibration of the screening racks 7 removes small nuts that do not meet packaging requirements, as well as broken nuts. The material is screened in the screening trough inside the 7. The vibration of the vibrating motor 6 accelerates the screening effect of the device. At the same time, the bottom of both sets of screening frames 7 is equipped with a shaking frame 13. Through the shaking structure of the shaking frame 13, the shaking frame 13 is vibrated and drives the screening frame 7 to shake. The two sets of screening frames 7 are connected by a connecting frame rod 9. The connecting frame rod 9 and the shaking frame 13 make the screening frame 7 shake at the same frequency, thereby improving the screening efficiency. The nuts slide down to the front receiving frame 11 under the vibration to complete the collection process after screening.

[0022] Example 2, as Figures 1-4 As shown, a nut processing screening device is used. Small nut particles that are screened off fall from the screening frame 7 into the inner screening frame 15 for further screening. The vibration motor 6, combined with the filter screen 16, vibrates and separates the nuts and the mixed peels and shells, causing the peels and shells to fall into the waste trough 12 for easy cleaning. The remaining nuts are collected through the filter screen 16 for use in other processing methods. The scraper plate 20 can scrape off the residual material in the filter screen 16. The operator pulls the handle 18 along the slide rail 19, which drives the scraper plate 20 to scrape off the debris remaining on the surface of the filter screen 16, facilitating the cleaning process of the device and improving its practicality.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
