[0023] The present utility model will be further described below through specific embodiments in conjunction with the drawings.
[0024] Example 1:
[0025] As Figure 1 shown, an automatic dust removal structure for an intake system includes a radiator 1, a sealing component, and an air filter 7. The radiator 1 is installed on a radiator sealing plate 10. The sealing component is connected to the radiator sealing plate 10. An air filter mounting hole 13 is provided on the sealing component. The air filter 7 is installed on the sealing component through the air filter mounting hole 13. The dust outlet of the radiator 1 and the dust outlet of the air filter 7 are connected through a dust removal hose 8. By connecting the dust outlet of the radiator 1 and the dust outlet of the air filter 7 through the dust removal hose 8, this system can achieve automatic discharge of dust and other impurities, effectively preventing the reduction of intake efficiency caused by dust accumulation, thereby improving the working performance of the engine.
[0026] Example 2:
[0027] As Figure 2 shown, an automatic dust removal structure for an intake system, different from that of Example 1, is that the sealing component includes a sealing plate 3. Sealing sponge fixing plates 4 are provided on both sides of the sealing plate 3. Sealing sponges 5 are provided on the side surfaces of the sealing sponge fixing plates 4. Sealing rubber strips 2 are provided on the side edges of the sealing plate 3 and the side edge of the radiator sealing plate 10. By providing sealing sponge fixing plates 4 on both sides of the sealing plate 3, with sealing sponges 5 provided on the side surfaces of the sealing sponge fixing plates 4, and sealing rubber strips 2 provided on the side edges of the sealing plate 3 and the radiator sealing plate 10, the sealing performance of the entire system is greatly enhanced, effectively preventing foreign impurities from entering and ensuring the cleanliness of the intake system.
[0028] Furthermore, brackets 14 are provided at the lower ends of both sides of the sealing plate 3. The sealing plate 3 is connected to the radiator sealing plate 10 through the brackets 14 and fasteners 11, and the fasteners 11 are bolts. Using brackets 14 and fasteners 11 (such as bolts) to connect the sealing plate 3 and the radiator sealing plate 10 not only makes the structure more stable and reliable but also facilitates assembly and maintenance work.
[0029] Furthermore, the dust removal hose 8 is connected to the dust outlet of the air filter 7 through a joint 6 and fastened by a clamp 12. The dust removal hose 8 is connected to the dust outlet of the air filter 7 through a joint 6 and fastened by a clamp 12, making the dust removal pipeline 8 easy to disassemble, clean, or replace, reducing the maintenance cost.
[0030] Furthermore, the dust outlet of the radiator 1 and the dust removal hose 8 are fastened by a clamp 12. The connection between the dust outlet of the radiator 1 and the dust removal hose 8 also adopts the fastening method of a clamp 12, ensuring the tightness of the connection part, reducing the dust leakage problem caused by improper connection, and improving the reliability of the entire system.
[0031] When the utility model is installed, the sealing sponge 5 is installed on the sealing sponge fixing plate 4, the radiator sealing plate 10 is installed on the radiator 1, and at the same time, the sealing sponge fixing plate 4 with the sealing sponge 5 is fastened to the radiator sealing plate 10 through the fastener 11 by the sealing plate 3. Then, the sealing strip 2 is installed on the sealing plate 3 and the radiator sealing plate 10. One end of the joint 6 is connected to the air filter 7, and the dust exhaust rubber pipe 8 is used to connect the joint 6 and the dust exhaust port of the radiator 1, and they are respectively fastened by the clamp 12.
[0032] The working principle of the utility model is as follows:
[0033] When the tractor is working, the engine fan 9 operates at different speeds according to the operating conditions of the tractor. The engine fan 9 sucks air to dissipate heat from the radiator 1. When the engine fan 9 sucks air, a negative pressure is generated in the area from the back of the radiator core to the front of the fan. At the same time, it is sealed with the engine hood through the sealing plate 3, so that the effect of the formed negative pressure difference is further enhanced, achieving the effect of negative pressure dust exhaust for the dust collected by the air filter 7 and the dust exhaust rubber pipe 8 without affecting the air intake requirements, extending the maintenance cycle time of the tractor intake system and reducing the maintenance cost.
[0034] At the same time, when the tractor operates under different working conditions, the rotational speed of the engine fan 9 and the air intake volume of the intake system change with the change of the working conditions of the tractor, so that the negative pressure dust exhaust capacity changes synchronously with the change of the working conditions of the tractor, meeting the dust exhaust needs of the tractor intake system under different working conditions.
[0035] Therefore, the utility model uses the air suction of the engine fan 9 to cooperate with the engine hood and the above sealing components to reduce the pressure in the area behind the radiator 1, generate a pressure difference between the front area and the rear area of the radiator 1, form a negative pressure, and make the dust automatically discharged, achieving the effect of automatic dust exhaust. It has low cost, compact structure, strong versatility, good use performance, extends the maintenance cycle of the air filter 7, and solves the problems of poor pulse dust removal effect of the existing tractor air filter, short air filter maintenance cycle and high maintenance cost.
