Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, specifically a livestock feed screening device. Background Technology

[0002] In the process of raising livestock, the main source of agricultural and pastoral feed is hay. In order to ensure the supply of feed for livestock, most hay needs to be stored in advance. The stored hay will inevitably be mixed with impurities such as soil, sand, and iron pieces. Once these impurities are ingested by livestock, they are difficult to excrete, thus causing livestock diseases. Therefore, hay needs to be screened before feeding to remove these impurities.

[0003] Chinese utility model patent CN222402268U discloses a feed screening device, including a support cover, a motor, and an L-shaped support frame. The top of the support cover is equipped with a feed hopper and a drying fan. The motor is located on the side of the support cover away from the ventilation hole. A reciprocating screw is mounted inside the support cover via a rotating shaft at the position corresponding to the motor. A slide rail is located on the side of the support cover corresponding to the reciprocating screw. A brush is positioned between the reciprocating screw and the slide rail. A screen and an inclined plate are located inside the support cover. A vibrator, in conjunction with a spring, vibrates and shakes the screen. Smaller feed particles fall onto the inclined plate and are collected at outlet B, achieving rapid feed screening. When feed accumulates, the motor drives the reciprocating screw to rotate, thereby moving the sliding sleeve and connecting rod along the slide rail. Simultaneously, an electric push rod drives the brush to approach the screen, quickly sweeping the feed to outlet A for collection by workers.

[0004] However, the above-mentioned patent still has the following shortcomings in actual use: the patent cannot perform continuous screening of feed, which affects the efficiency of the screening work. Utility Model Content

[0005] The purpose of this invention is to provide a livestock feed screening device to solve the problem mentioned in the background art that the feed cannot be continuously screened, thus affecting the efficiency of the screening work.

[0006] The technical solution of this utility model is:

[0007] A livestock feed screening device includes a conveyor frame, a conveying assembly, an operating box, a screening box, two supports, two connecting plates, and two vibration assemblies. The conveying assembly is installed inside the conveyor frame. The two supports are symmetrically arranged on the outer wall of the conveyor frame.

[0010] Furthermore, two sliding doors are connected to the top outer wall of the control box, and the sliding doors are provided with handles integrally formed thereon.

[0011] Furthermore, the sliding door is equipped with a transparent observation panel.

[0012] Furthermore, the bottom of the conveyor frame has four support legs arranged in a rectangular shape.

[0013] This utility model provides an improved livestock feed screening device, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this utility model involves feeding the feed to be screened into the operating box via a feeding box. The feed then falls into the screening box. Next, two vibrating components drive two connecting plates to move up and down repeatedly. The two connecting plates drive the screening box to move up and down repeatedly within the operating box. The feed in the screening box vibrates as it moves up and down, and multiple sieve holes quickly screen the feed. After screening, feed that meets the size requirements falls through the sieve holes and the discharge port onto the conveying component. Finally, the conveying component transports the feed away, realizing continuous screening of the feed and ensuring the efficiency of the screening work.

[0015] Secondly, this utility model uses a conveyor motor to drive one of the conveyor shafts to rotate, which in turn drives the corresponding conveyor roller to rotate, and the conveyor roller then drives the conveyor belt to rotate, thus conveying the feed that falls onto the surface of the conveyor belt.
