Straw rolling machine

Abstract

The invention relates to the technical field of processing of organic fertilizers, in particular to a straw rolling machine. The straw rolling machine comprises a pair of pressing rolls, wherein each pressing roll is in a cylinder shape and is inclined, a first pressure valve is arranged at an opening of the lower end of each pressing roll, a plurality of conveying pipes and a plurality of first grooves are arranged at the side wall of each pressing roll, the first grooves are communicated with the conveying pipes, the pipe diameter of the lower end of each conveying pipe is greater than the pipe diameter of the upper end, and a second pressure valve is arranged at the lower end of each conveying pipe; a piston plate and a strip-shaped convex block are arranged at the inner wall of each pressing roll, each convex block is fixedly connected with the corresponding pressing roll, each piston plate is glidingly matched with the corresponding convex block, and the side wall of each piston plate is also glidingly connected with inner wall of the corresponding pressing roll; a reset spring is arranged between each piston plate and the corresponding pressing roll, the upward end of each piston plate is fixedly connected with a support plate, the other end of each support rod is positioned at the exterior of the corresponding press roll and is fixedly connected with a cylindrical cam, and a limiting rod is arranged at the exterior of each pressing roll and is matched with the corresponding cylindrical cam. The straw rolling machine has the advantages that the juice separated in the straw rolling process can be collected, and the purpose of fully utilizing the raw material of the organic fertilizer is realized.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer processing, in particular to a straw rolling machine. Background technique [0002] Organic fertilizers are mainly processed from raw materials such as animal and plant wastes and plant residues. They eliminate toxic and harmful substances and are rich in a large number of beneficial substances. They can not only provide comprehensive nutrition for crops, but also have a long fertilizer effect, which can increase and renew the soil. Organic matter, which promotes the reproduction of microorganisms, thereby improving the biological activity of the soil. [0003] Corn stalks are one of the commonly used raw materials for organic fertilizers. Before using corn stalks to make organic fertilizer, it needs to be rolled to reduce the hardness of corn stalks and facilitate its crushing. Now, commonly used stalk rolling machine is made up of a pair of pressure rollers and the rotating motor th...
