Description

Technical Field

[0001] The utility model relates to the technical field of fixed knife installation structures, in particular to a fixed knife installation structure and a double-shaft crusher. Background Art

[0002] With the booming economy of our country, animal husbandry has been developing rapidly, and the demand for forage has been increasing day by day. Natural forage can no longer meet the needs of the development of animal husbandry. Therefore, corn straw and wheat straw have gradually become the forage for animal husbandry in some areas.

[0003] The mechanized forage harvesting technology has very mature experience in advanced countries in Europe and the United States. The main purpose of the shredder is to cut and crush the straw while harvesting it and return it to the field. The straw can be crushed and processed and directly fed to livestock, so the baler's shredding mechanism is constantly updated.

[0004] The crushing mechanism of a traditional baler consists of a rotating moving blade and a fixed blade. The rotation of the moving blade drives the grass to contact the fixed blade, thereby achieving the effect of kneading and crushing. The traditional way to install the fixed blade is to weld a group of fixed blades to the fixed blade seat, and use two bolts to penetrate from the inside to the outside to fix a row of fixed blades. There are two existing ways to install the fixed blades. One is to place the fixed blades completely inside the frame, and use bolts to weld a group of fixed blades to the frame. The other is to leave the blade outside the frame to facilitate the adjustment of the cutting length of the blade.

[0005] However, the prior art has the following disadvantages: (1) the prior installation method is not easy to disassemble and assemble, and the welding strength is insufficient, so the fixed blade is easy to break; (2) the replacement cost is high. Once the fixed blade is worn, it is not possible to replace a single fixed blade, but a group of fixed blades must be replaced. Utility Model Content
