Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to a straw bundling machine. BACKGROUND

[0002] In the process of agricultural production, straw is the main residue after crop harvesting. The traditional straw treatment method is mostly burning or piling, which not only causes waste of resources, but also may pollute the environment. With the development of agricultural mechanization, straw bundling machines, as an efficient straw treatment equipment, are gradually favored by farmers.

[0003] The patent document with the published announcement number CN218042597U provides a straw bundling machine. A compression chamber is arranged in the inside of the machine body. The compression chamber is connected with a material conveying pipe. A drive cavity is formed between the baffle and the inner wall of the machine body. A drive screw is installed in the drive cavity. A drive motor is connected to one end of the drive screw. Two groups of drive screws are connected. Two groups of threaded sleeves are installed on the drive screw. The drive screw rotates, and the two groups of threaded sleeves move towards or away from each other. The two surfaces of the threaded sleeves are respectively connected with connecting rods. The end of the connecting rod is connected with a pressing plate. The pressing plate is installed in the compression chamber. Two drives are driven at the same time, so that the pressing plate compresses the straw in the compression chamber. The pressure is large, and the bundling is tight.

[0004] In actual use, the distance between the two groups of pressing plates is uncontrollable due to the influence of the amount of straw. If the amount of straw is too much, the distance between the two groups of pressing plates will be larger. There is a lack of lateral compression movement of the straw, which leads to that the bundled straw is not tight enough. If the amount of straw is too small, the upper and lower ends of the straw may not be compressed tightly enough due to the arc shape of the pressing plate. Therefore, the recovery rate of the straw is reduced. Content of the utility model
