Description

Technical Field

[0001] The utility model relates to the technical field of harvesters, in particular to an air pre-filter dust removal device. Background Art

[0002] During harvester operation, the air is first filtered through an air pre-filter to remove dust and impurities, ensuring the cleanliness of the air entering the engine. Currently, most air filters have a mesh-type intake structure. Due to the harsh operating environment of harvesters, after a period of operation, the pre-filter surface absorbs a large amount of crop straw and dust, causing the mesh to clog, resulting in reduced air intake efficiency, incomplete diesel combustion, increased fuel consumption, and engine weakness. The large amount of poplar and willow catkins during wheat harvest in some areas exacerbates this problem, and in severe cases, the pre-filter mesh can be completely blocked, preventing air from entering. To ensure the harvester's normal operation, the operator must clean the pre-filter regularly, which not only increases the operator's workload but also affects harvesting efficiency.

[0019] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0020] See also Figure 1-3 An embodiment of the utility model provides an air pre-filter dust removal device, including an air pre-filter body 5, a base 1 is fixedly connected to the air pre-filter body 5, and a push rod motor 2 is fixedly connected to the upper side of the base 1, and a fixing seat 3 is fixedly connected to the upper side of the push rod motor 2, a brush 4 is installed on the fixing seat 3, and the fixing seat 3 and the brush 4 are both sleeved on the air pre-filter body 5.

[0021] The push rod motor 2 is connected to the manual control switch 6 and the automatic controller 7 through wires.

[0022] The fixing seat 3 includes a brush seat and a sleeve. The lower side of the brush seat is fixedly connected to the sleeve. The upper end of the push rod motor 2 is fixedly connected to a joint. The sleeve is fixedly connected to the joint. The brush 4 is installed on the brush seat.

[0023] The air pre-filter body 5 is disposed on one side of the engine 8 , and the gas filtered by the air pre-filter body 5 enters the engine 8 .

[0024] During use, the utility model is welded to the filter body 1 to support the entire structure. The push rod motors 2 are symmetrically mounted on the base 1, one in front and one behind. The sleeve on the fixed seat 3 is fixedly connected to the joint at the upper end of the push rod motor 2. The brush 4 is mounted on the brush seat on the fixed seat 3. When the surface of the air pre-filter body 5 is clogged with dust, the push rod motor 2 runs and drives the fixed seat 3 to move up and down. The brush 4 moves with the fixed seat 3 and pushes the dust and grass clippings away from the air filter surface, so that the air filter intake mesh is unobstructed, ensuring the normal operation of the engine 8. The push rod motor 2 can be automatically started and stopped at certain intervals by the automatic controller 7, or manually started and stopped by the button on the manual control switch 6. The user can choose the control mode according to the actual situation.
