Feed crushing and screening equipment for agricultural production

Abstract

The invention discloses feed crushing and screening equipment for agricultural production. The equipment structurally comprises a fine material screening device, a supporting cross rod, a crushing cavity, a driver and a machine body, wherein the fine material screening device is arranged at the right side of the supporting cross rod and movably connected to the supporting cross rod; a crushing shaft in the middle of the crushing cavity is connected to an output belt pulley of the driver; the driver is arranged at the top of the machine body; and an inner cavity of the crushing cavity is communicated with the interior of the fine material screening device. The equipment has the beneficial effects that large pellet feed is intercepted through a flow stopper, the edge of a guide cavity is fixed through a guide plate, the flow speed of a cavity formed by the guide plate and an auxiliary side plate is small, downward separation of part of the large pellet feed is facilitated, airflow is slowed down by the fine powder feed passing through a screening pipe at the top, the motion frequency of the powder feed is reduced, and the influence of a large amount of flying dust on the body of a worker during discharging is avoided.

Description

technical field [0001] The invention relates to feed crushing and screening equipment for agricultural production, which belongs to the field of agricultural production equipment. Background technique [0002] Feed grinder is mainly used to crush various feeds and roughages. The purpose of feed crushing is to increase the surface area of ​​feed and adjust the particle size. Increasing the surface area improves palatability, and it is easy to contact with digestive juice in the digestion side, which is conducive to improving digestibility. , to better absorb the nutritional components of the feed. During the process of grinding and screening dry materials, a large amount of dust will be generated. The dust contains a large amount of fine materials. Generally, farmers do not process the fine materials, and the dust will be generated during long-term operation. Harmful if inhaled into the lungs. Contents of the invention [0003] Aiming at the deficiencies in the prior art, ...

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a feed crushing and screening equipment for agricultural production to solve the problem of grinding and screening dry materials. A large amount of dust will be generated, and the dust contains a large amount of fine materials. Generally, farmers do not treat the fine materials, and the dust inhalation into the lungs during long-term operations will cause harm to the body.
