The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a technical solution:

A chain-operated leveling and cleaning mechanism, including a box body 1, a chain 7, a scraper 9 and a screen 10, as shown in Figure 1 of the specification, the top wall of the box body 1 is provided with a feed port 2, and the feed port 2 is set in the box In the upper right corner of the body 1, the air-selected material enters the box body 1 from the feed port 2, and the side wall of the box body 1 away from the feed port 2 is provided with a sundry outlet 3, and the sundry outlet 3 It is arranged on the left side wall of the box body 1, and is used to transport sundries out.

A bracket 101 is fixed in the inner cavity of the box body 1, and the bracket 101 is fixedly inserted on the inner wall of the box body 1, and there are no less than two brackets 101, and the bracket 101 is arranged at the sundries outlet 3, so that The screen 10 is tilted toward the debris outlet 3, and the two ends of the screen 10 are flexibly connected with the bracket 101. The screen 10 is obliquely arranged in the inner cavity of the box body 1, and the inclination angle is set at 15°, which can facilitate the entry of materials into the screen. After the net 10, it slides down along the screen 10, and the material enters from the feed port 2 and falls onto the screen 10 for screening. The sundries on the screen 10 can move out from the sundry outlet 3 along the screen 10, Both ends of the screen 10 are bent and hung on the bracket 101, and the connection between the screen 10 and the bracket 101 is provided with tension bolts 102, so that the screen 10 adopts a frameless design, and no frame is needed to carry out the screen 10. Fixed, the area of the screen 10 is utilized to a greater extent, and the tension of the screen 10 can be adjusted more conveniently by adjusting the tension bolt 102, and at the same time, it can be quickly replaced.

The screen 10 is provided with a driving sprocket 4 and a driven sprocket 5 near the feeding port 2. The driving sprocket 4 and the driven sprocket 5 are all fixed on the inner side wall of the box body 1 through a rod body. The driving sprocket 4 It is arranged below the feed inlet 2, the driven sprocket 5 is arranged near the debris outlet 3, the driving sprocket 4 is connected to the reduction motor 6, and the reduction motor 6 drives the driving sprocket 4 to rotate through the belt (the belt is not shown in the figure) Out), the reduction motor 6 is placed in the casing 1, and the driving sprocket 4 and the driven sprocket 5 are connected by a chain 7, and the driven sprocket 5 is driven to rotate by the driving sprocket 4 and the chain 7.

The cleaning device is fixed on the chain 7, and the cleaning mechanism composed of the driving sprocket 4, the passive sprocket 5 and the cleaning device on the chain 7 operates in a single cycle in a certain direction. There are 5 groups of cleaning devices, which can run in a cycle. When cleaning the screen cloth 10 better.

The cleaning device includes a mounting block 8 and a scraper 9. The mounting block 8 is fixedly installed on the chain 7 through bolts and nuts. When the chain 7 moves, the mounting block 8 moves together with the chain 7. The mounting block 8 is provided with a scraper 9. The sprocket 4 and the driven sprocket 5 are symmetrically arranged in two groups, and the scraper 9 is installed on the symmetrical mounting block 8, so that the scraper 9 on the side close to the screen 10 is in movable contact with the surface of the screen 10, and the scraper 9 on the cleaner The scraper 9 is divided into two different materials, a soft board and a hard board, so that the hard and soft sundries on the screen 10 can be effectively cleaned at the same time. Hard sundries such as stones, glass pieces, steel wire, etc. Blocks, etc., soft debris such as: straw, hemp rope, plastic bags and other entangled substances can completely and continuously clean up the debris on the sieve plate 10 and push it to the debris outlet 3, while ensuring that the finished material can be used when the output increases. When it is large, it will not quickly flow out together with sundries, effectively ensuring the separation effect and output. A large number of finished products flow into the finished product discharge pipe 11 through the mesh on the screen 10. It is precisely because of this cleaning mechanism that greatly improves Processing capacity, and the cleaning equipment currently used in the market does not have such a function. After a period of use, it is necessary to manually clean up the debris wrapped around the sieve plate, otherwise it will block some of the sieve holes, limiting the separation effect and output of the product , and compared with similar products, the utility model has a processing output increased by more than 30-50%, and the utility model also has a variable speed function, which can easily adjust the size of the output at any time, which greatly facilitates the needs of customers.

The side of the screen 10 away from the chain 7 is provided with a finished product discharge pipe 11. The finished product discharge pipe 11 is inserted through the bottom wall of the box body 1. The finished product discharge pipe 11 is used to receive the materials screened by the screen 10. The finished materials are collected, and the outer wall of the box body 1 is fixed with a debris collection frame 13 under the debris outlet 3, and the debris is conveyed from the debris outlet 3, and then enters the debris collection frame 13, and the debris is recycled and collected .

As a preference, both sides of the finished product discharge pipe 11 are connected with the lower trip board 12, and the end of the lower trip board 12 away from the finished product discharge pipe 11 is fixed on the inner wall of the box body 1, and the two lower trip boards 12 are arranged so that The finished product discharge pipe 11 does not need to be set too large in size. The finished product materials are first gathered by the lower trip plate 12, and then collected into the finished product discharge pipe 11, which is very convenient.

As another preference, a baffle 14 is fixed on the side of the debris collection frame 13 away from the debris outlet 3, and the baffle 14 is arranged at the debris outlet 3 to prevent debris movement from causing debris to move too fast when the debris is output. Things can't get into the debris collection frame 13 well.

Working principle: Driven by the deceleration motor 6, the driving sprocket 4 is connected to the chain 7 to transfer kinetic energy to synchronously drive the cleaner on the chain 7 to run, and drive the cleaner to cycle in a certain direction, which can clean up the dust on the screen 10. At the same time, it can completely separate the material from the impurities, without manual treatment, and will not affect the output and working speed.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes and modifications can be made to these embodiments without departing from the principle and spirit of the present invention , replacements and modifications, the scope of the present utility model is defined by the appended claims and their equivalents.
