Grain suction machine

Abstract

This utility model provides a grain suction machine, including a vehicle body, a suction box mounted on the vehicle body, and a suction pipe connected to the suction box on one side of the vehicle body. The vehicle body is equipped with an adjustment mechanism for adjusting the position of the suction pipe. A first electric cylinder on the first arm controls the extension and retraction of the second arm, thereby driving the extension and retraction of the second guide pipe, thus changing the position of the suction pipe. This facilitates suction of the front and rear of the suction area, improving the efficiency of the suction process and simplifying the operation. A drive motor controls the drive gear to rotate, thereby driving the rotary table to rotate. The rotary table, through a support plate, drives the first arm, the second arm, and the suction pipe to rotate and adjust, causing the suction pipe to swing along an arc path. The second electric cylinder controls the lifting of the first arm, allowing the height of the suction pipe to be adjusted according to the material height. This device has a large rotation angle, strong adaptability, and can quickly adjust the position of the suction pipe as needed, thereby improving the efficiency of the suction process.

Description

Technical Field

[0001] This utility model relates to the field of grain suction machine technology, specifically a grain suction machine. Background Technology

[0002] A grain suction machine is a mechanical device used for conveying granular materials such as grains and feeds, and is widely used in agriculture, grain processing, and warehousing. The working principle of a grain suction machine is to use a fan to generate negative pressure airflow, drawing the material into a pipe and transporting it to a designated location. Currently, grain suction machines generally adjust the suction position by controlling the suction pipe to swing in an arc. However, materials before and after the suction position cannot be sucked up, requiring the machine body to be moved. Moving the machine body requires subsequent feeding and receiving equipment to coordinate, making the operation relatively cumbersome. Therefore, a grain suction machine that can quickly adjust the suction position within a small range is needed to improve suction efficiency. Utility Model Content
