An agricultural cotton dehulling machine

Abstract

The invention discloses an agricultural cotton hulling machine. Its structure includes a feeding hopper, a hulling device, a transmission box, a discharging box and a discharging plate. The front surface of the device is provided with a transmission box and is connected by transmission. The crushing head is driven by a spring rod to perform telescopic extrusion, so as to prevent the cotton from shrinking during extrusion and crushing, and improve the crushing ability of the cotton shell. Sliding, elastic force is generated during the movement of the frame plate, so that the cotton stuck between the crushing heads is ejected out. When the roller body rotates, the cam pushes down the lower pressure rod, and the lifting rod is carried out inside the fixed frame. The vertical lift drives the fixed rod and the connecting frame to squeeze down, the torsion shaft makes the pendulum rotate slightly, and the lower end of the pendulum is squeezed down, so as to press down on the fluffy cotton after shelling to avoid Fluffy cotton is jammed inside the lower end of the separation box.

Description

technical field [0001] The present invention relates to the field of agricultural equipment, more particularly, to an agricultural cotton hulling machine. Background technique [0002] Cotton is one of the most important crops in the world. The large output and low production cost make cotton products relatively cheap. After the cotton grows full, the cotton needs to be plucked from the tree. The outer shell of the cotton is removed by the shelling machine, and the pressure generated by the rotating roller inside the shelling machine breaks the outer shell of the cotton, so that the cotton and the outer shell are separated, but due to the strong flexibility of the cotton itself, In the process of rotating and squeezing the cotton, the rotating roller inside the shelling machine makes the cotton itself shrink, so that it is difficult to break the outer shell of the cotton, resulting in a decrease in the shelling effect of the cotton, and the cotton after partial shelling is r...

Problems solved by technology

[0002] Cotton is one of the most important crops in the world. It has a large output and low production cost, which makes the price of cotton products relatively low. After the cotton grows full, it needs to be picked from the tree. The picked cotton has a shell. The shell of the cotton is removed by the sheller, and the pressure generated by the rotating roller inside the sheller crushes the shell of the cotton, so that the cotton is separated from the shell, but because the cotton itself has strong flexibility, During the process of rotating and squeezing the cotton, the rotating roller inside the shelling machine makes the cotton itself shrink, making it difficult to break the cotton shell, resulting in a decline in the shelling effect of the cotton. At the same time, the partially shelled cotton is relatively fluffy. The volume of the cotton increases, and it is easy to block inside the sheller, making it difficult to discharge from the sheller.
