Description

A raw material cleaning screen for feed production

Technical Field

The utility model relates to the field of agricultural cleaning devices, in particular to a raw material cleaning screen for feed production.

Background Art

Feed raw material cleaning screen, also known as primary cleaning screen, is a commonly used cleaning equipment, mainly used to screen and remove debris in feed raw materials, such as wheat straw, corn leaves, corn cobs, rice straw, stones, hemp ropes, etc. Specifically, the material falls into the chute from the feed inlet and passes through the running drum screen. In this process, larger impurities cannot pass through the sieve holes, so they are screened out by the drum screen and flow out through a special discharge port. During the use of the cleaning screen equipment, due to the appearance of various debris, it is easy to cause the sieve holes to be blocked after a period of use, which affects the efficiency of feed raw material removal. In this regard, the prior art relies more on manual cleaning or other auxiliary tools to clean the drum screen. For example, the utility model patent with application number 201721286950.0 and the name of a powdered feed cleaning screen discloses a cleaning screen that is a structural improvement on the existing cleaning screen drum screen. The controller controls the telescopic parts to continuously extend and retract, allowing the vibration roller to hit the screening drum, causing the side wall of the screening drum to vibrate so that the powdered feed can be separated from the screening hole, so that the screening hole can continue to be screened, ensuring the screening effect and making the screening effect of the powdered feed cleaning screen more stable. However, manual cleaning is time-consuming and labor-intensive, and the above-mentioned improvement to the structure is to improve the structure of the drum screen or the screening drum, giving it a certain vibration force, so that the impurities in the screen hole are cleaned up. This method is relatively costly, and it is not easy to modify ordinary drum screens, and it does not have the significance of wide promotion.

DETAILED DESCRIPTION

The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

As shown in FIG1 , it is a schematic diagram of the structure of the raw material cleaning screen for feed production of the utility model. Please refer to FIG2 , the cleaning screen of the utility model is provided with a casing, a base 2 located at the bottom of the casing and a drum screen 3 located in the casing, the casing is provided with a feed inlet and a discharge port (not marked in the figure), the casing is provided with an upper bottom surface 11 and a lower bottom surface 12 parallel to each other, a front end surface 13 and a rear end surface 14 parallel to each other, two side surfaces 15 parallel to each other and an inclined plate surface 16 located between the upper bottom surface 11 and the lower bottom surface 12, the upper bottom surface 11 and the lower bottom surface 12 are provided with a plurality of rollers 16 disposed in the casing, and the rollers 16 are provided in the casing. , a front end face 13, a rear end face 14, two side faces 15 and an inclined plate face 16 form an accommodating space, and the drum screen 3 is located in the accommodating space. As shown in FIG. 2 , an observation window 17 is provided on the inclined plate face 16.
