Cutter assembly

Abstract

The invention provides a cutter assembly. The assembly comprises a grass discharging channel, a grass inlet and a grass outlet, the grass inlet and the grass outlet are located at the two ends of the grass discharging channel, and a movable knife roller is arranged in the grass discharging channel. Multiple movable blades are spirally arranged and distributed and detachably installed on the movable knife roller, any movable blade is parallel to the cross section of the movable knife roller, and a fixed knife base is arranged in the grass discharging channel at the side, close to the grass inlet, of the movable knife roller. Multiple fixed blades are evenly mounted on the fixed knife base at intervals in the same direction, when the movable knife roller is driven to rotate to any position, it can be guaranteed that all the movable blades can pass through the gaps between the fixed blades, in other words, the cutting state between the movable blades and the fixed blades can be kept all the time, and under the conventional rotating speed of the movable knife roller, cutting-up efficiency is still improved, and the power output cost caused by increasing the rotating speed is reduced. A scattering structure is arranged on the grass outlet and is suitable for uniformly scattering the crushed grain grass. The cut-up grain grass is uniformly spread in the farmland through the scattering structure, so that the grain grass is prevented from being accumulated in the farmland, the labor is reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of crushing devices, in particular to a chopper assembly. Background technique [0002] It is an important measure to meet environmental protection requirements to prevent the burning of straw from polluting the air and to use it as organic fertilizer to fertilize the land. To achieve this purpose, the existing combine harvester All have been equipped with a crushing device. [0003] If the length of the straw left by the combine harvester is too long, farmers generally use the method of burning the straw to clean up the field. When burning the straw, a large amount of smoke and dust are generated to seriously pollute the air. The greenhouse effect; runs counter to the environmental protection requirement that reduces the carbon dioxide emission in the atmosphere. [0004] In order to avoid the aforementioned situation, the existing combine harvesters use low stubble to harvest crops, which reduces the hei...
