Description

Technical Field

[0001] The utility model relates to the technical field of grain harvesters, in particular to a vibration dust removal mechanism of a grain harvester. Background Art

[0002] Grains usually mature in autumn. If acres of grain have to be harvested manually, it would be a waste of manpower and inefficient. In order to meet the requirements of modern mechanical harvesting, workers are required to drive harvesters along the fields to harvest rice and fruits. These materials are inevitably mixed with dust when entering the carriage and need to be screened.

[0003] Therefore, most carriages are equipped with dust removal mechanisms, but most ordinary dust removal mechanisms are single filter screening, lacking vibration assistance. Materials with particle size matching the mesh holes are prone to blockage here, which in turn affects the screening pass rate of dust and materials, and the dust removal effect is not ideal.

[0004] Now, a novel vibration dust removal mechanism of a grain harvester is proposed to solve the above problems. Utility Model Content

[0010] Preferably, the bracket is sleeved on the center of the top of the U-shaped discharge pipe, and the bottom of the water pipe passes through the bracket and the spray plate.

[0011] Preferably, the material pump can extract dust from the shell into a U-shaped discharge pipe, and the pipe mouth of the U-shaped discharge pipe is arranged in the frame.

[0012] Preferably, a liquid tank is fixed on the left side of the top end of the outer body of the box body, an air tank is installed on the upper right side of the liquid tank, a suction groove is provided on the left side of the top of the box body, and a connecting pipe is fixed between the suction groove and the liquid tank, an air pump is installed on the connecting pipe, the connecting pipe is connected to the output end of the air pump, the input end of the air pump is connected to a U-shaped air inlet pipe, and the end of the U-shaped air inlet pipe away from the air pump passes through the top of the liquid tank and extends inward, and clean water is stored in the liquid tank.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the vibration dust removal mechanism of the grain harvester not only avoids screen clogging and quickly removes dust, but also cleans the residual dust inside;

[0015] (1) By fixing a screen frame between the ends of the cylinder piston rod, the cylinder on the left or right side has the same movement trajectory, which can push the screen frame in the shell left and right, and separate and shake off the grain and dust through the filter screen at the center. The grain is trapped in the screen frame, while the dust falls to the bottom of the shell and is pumped out by the material pump connected to the notch.

The U-shaped pipe can also prevent the liquid from flowing back into the box, which not only discharges the dust but also prevents the dust from being raised.

[0017] (3) A liquid tank is fixed on the left side of the top of the outer casing. If there are still particles remaining inside the casing but not in the shell or the screen frame, after the conveyor belt has finished delivering the rice collected by the harvesting cage, the air pump on the top is started, and the gas mixed with dust is extracted from the suction trough through the connecting pipe and injected into the liquid tank below the clean water level. The gas is adsorbed and fused by the clean water and then discharged from the air tank to maintain the cleanliness of the internal environment of the casing. BRIEF DESCRIPTION OF THE DRAWINGS
