Problems solved by technology

[0003] Existing threshers usually use a beating roller driven by a motor to beat agricultural products through the high-speed rotating beating roller. For example, the grains of rice are separated from the straw. The problem is that the labor intensity is high, and the later straw processing more troublesome

Embodiment Construction

[0031] The front and rear orientations in this example are based on the running direction of the crops, with figure 1 For example, the direction of the feeding hopper is the front, that is, the left side in the figure, and the direction where the cutter roller is located is the rear, that is, the right side in the figure.

[0032] Such as figure 1 , 5 Among them, a thresher includes a first roller set 1, a second roller set 2 and a third roller set 3, and the first roller set 1, the second roller set 2 and the third roller set 3 are rotatably mounted on On the frame, it is preferably supported on the frame by bearings.

[0033] A screen 4 is provided between the first roller group 1 and the second roller group 2. The screen 4 is a replaceable structure, corresponding to grains such as rice, wheat and rapeseed respectively, and a first discharge hopper is provided below the screen 4. 6. Used to collect falling crop particles;

Abstract

The invention provides a thresher which comprises a first roller assembly, a second roller assembly and a third roller assembly. A screen mesh is arranged between the first roller assembly and the second roller assembly and a first discharge hopper is arranged below the screen mesh; a rotating threshing roller and a screen mesh are arranged between the second roller assembly and the third roller assembly, and a second discharge hopper is arranged below the rotating threshing roller and the screen mesh; A shear mechanism is arranged behind the third roller assembly. A threshing mode of rolling combined with striking has a good threshing effect and is especially suitable for the threshing operation of wheat, rice and rape. The shear mechanism is capable of automatically crushing straws to achieve a variety of functions and has the advantages of reducing labor intensity and improving labor efficiency. The thresher is compact in structure and easy to process and produce, so the thresher is suitable for use in mountainous areas.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a thresher with multiple functions suitable for mountainous areas. Background technique [0002] In some areas, such as mountainous and hilly areas, large harvesters cannot be used for crop processing due to uneven terrain. It makes the threshing of crops more troublesome, and some areas even use beating or stone grinding for threshing. [0003] Existing threshers usually use a beating roller driven by a motor to beat agricultural products through the high-speed rotating beating roller. For example, the grains of rice are separated from the straw. The problem is that the labor intensity is high, and the later straw processing More troublesome. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a threshing machine, which can improve the threshing efficiency and reduce labor intensity. use. [0005] In order to solve the abov...
