Description

Technical Field

[0002] The straw shredder can crush combustible crop waste materials such as corn stalks, straw, peanut hulls, and bean stalks. This prevents wasteful burning of these crop straws, effectively protecting the environment and effectively developing renewable energy. It offers reliable performance, simple and convenient operation, and can be used with a wide range of raw materials, including corn stalks, straw, peanut hulls, and bean stalks.

[0029] As a further preferred embodiment of the present invention, the first belt transmission mechanism 7 includes a first driving wheel 7-1, a first driven wheel 7-2 and a belt; the first driving wheel 7-1 is installed on the output end of the drive motor 2; the first driven wheel 7-2 is clamped on the first rotating shaft 6; the first driving wheel 7-1 drives the first driven wheel 7-2 to rotate through the belt, thereby driving the rotation of the first rotating shaft 6 and the crushing knife unit 5.

[0030] As a further preferred embodiment of the present invention, the size ratio between the first driving wheel 7-1 and the first passive wheel 7-2 is 6:1, so that the first passive wheel 7-2 can obtain a higher rotation speed, thereby accelerating the crushing of the straw.

[0031] As a further preferred embodiment of the present invention, the second belt transmission mechanism 11 includes a second driving wheel 11-1, a second driven wheel 11-2 and a belt; the second driving wheel 11-1 is clamped on the first rotating shaft 6; the second driven wheel 11-2 is clamped on the second rotating shaft 10; the first rotating shaft 6 drives the second driven wheel 11-2 to rotate through the belt, thereby driving the discharge paddle 9 to rotate.

[0032] As a further preferred embodiment of the present invention, a filter screen 14 is further provided inside the pulverizing cylinder 1 ; the filter screen 14 is located between the bottom of the pulverizing blade unit 5 and the top of the discharge pipe 8 .

The outer diameter of the first passive wheel 7-2 is several times smaller than the outer diameter of the first active wheel 7-1, and the first passive wheel 7-2 obtains a higher rotation speed. Since the first rotating shaft 6 is connected to the first passive wheel 7-2, the crushing knife unit 5 rotates accordingly, thereby achieving straw crushing. The crushed straw falls into the discharge pipe 8 after passing through the filter screen 14. When the straw fragments accumulate to a certain extent, the pushing rod 15 is pushed back and forth to push the straw fragments into the discharge bin 3;
