[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figure 1-3 As shown, a gearbox heat dissipation device for a crawler-type agricultural machinery includes a gearbox body 16 and a respirator 17 disposed on the top of the gearbox body 16, and also includes a filtering mechanism disposed on the respirator 17 for preventing dust and impurities from entering the gearbox body 16;

[0024] The filtering mechanism includes an air intake connector 1 arranged above the respirator 17, a hose 2 is connected between the bottom of the air intake connector 1 and the respirator 17, a mounting cover 3 is threadedly connected to the top of the air intake connector 1, an air intake pipe 5 is connected and fixed on the outer wall of the air intake connector 1, a dustproof ring plate 4 is arranged in the air intake connector 1, an annular groove matching the dustproof ring plate 4 is opened on the inner wall of the top end of the mounting cover 3 and the inner wall of the bottom end of the air intake connector 1, and the two ends of the dustproof ring plate 4 are respectively inserted into the two annular grooves;

[0025] By setting the dust ring plate 4 and the hose 2, the hose 2 is connected to the respirator 17, and the length of the hose 2 can be used to lead the air intake connector 1 to a high place with less dust. Therefore, during the process of gas absorption by the respirator 17, the air enters the air intake connector 1 through the suction pipe 5 and is filtered by the dust ring plate 4, and the particle dust is blocked on the outer ring of the dust ring plate 4, thereby preventing the external dust from being sucked into the gearbox and increasing the burden on the oil filter. When exhaling, the gas is blown into the air intake connector 1 from the hose 2 and blown from the inside of the dust ring plate 4 to the outside, so that the dust attached to the dust ring plate 4 can be blown off, thereby achieving the dust cleaning effect.

[0026] And by using the annular grooves on the inner wall of the top end of the mounting cover 3 and the inner wall of the bottom end of the air intake connector 1, the dust ring plate 4 can be firmly clamped between the air intake connector 1 and the mounting plate 8, thereby ensuring the stability of the dust ring plate 4 in the air intake connector 1;

[0027] And by utilizing the threaded connection between the air intake connector 1 and the mounting cover 3 , the mounting cover 3 can be separated from the air intake connector 1 by turning the knob of the air intake connector 1 , thereby making it convenient for personnel to open the air intake connector 1 and inspect and replace the dust ring plate 4 inside the air intake connector 1 .

[0028] However, in reality, the air exhausted from the gearbox is mostly high-temperature hot air, which contains a large amount of water vapor. The water vapor in the air intake joint 1 can easily cause the dust filtered on the dust ring plate 4 to become damp and stubbornly adhere to the outer surface of the dust ring plate 4. It is often difficult to remove the dust from the dust ring plate 4 by the hot air backblowing method.

[0029] For this purpose, refer to Figure 2 and Figure 3 As shown, it is worth noting that a vibration connection component is provided on the mounting cover 3;

[0030] The vibration connection component includes a mounting plate 8 disposed above the mounting cover 3, a plurality of spring telescopic rods 9 are fixed around the mounting plate 8 and the mounting cover 3, and the mounting plate 8 is provided with mounting holes;

[0031] By setting the shock-supply connection component and utilizing the mounting holes on the mounting plate 8, the mounting cover 3 and the air intake connector 1 can be conveniently mounted as a whole at a high position on the vehicle body by means of bolts, and by utilizing the spring telescopic rod 9, the mounting cover 3 and the air intake connector 1 are elastically connected to the vehicle body at a high position, so that the mounting cover 3 and the air intake connector 1 as a whole are easily shaken up and down by the bumps during vehicle operation, and the dust on the dustproof ring plate 4 can be shaken off by the shaking.

[0032] Further, refer to Figure 3 As shown, it is worth noting that a shock component is provided in the suction joint 1;

[0033] The shock component includes a movable sheet 10 slidably arranged inside the dust ring plate 4 and a plurality of striking parts arranged around the outer periphery of the movable sheet 10. The top of the mounting cover 3 is connected and fixed with a mounting sleeve 6, and a telescopic rod 7 is vertically arranged inside the mounting sleeve 6. One end of the telescopic rod 7 passes through the mounting sleeve 6 and is fixed to the mounting plate 8, and the other end of the telescopic rod 7 passes through the inner side of the dust ring plate 4 and is fixed to the movable sheet 10.

[0034] The striking part includes two supporting pieces 11 symmetrically fixed on the inner wall of the top end of the mounting cover 3, a movable column 12 fixedly arranged between the two supporting pieces 11, and a ball rod 13 rotatably sleeved on the rod body of the movable column 12. A notch 14 is provided on the outer periphery of the movable piece 10, a connecting column is fixed between the inner walls on both sides of the notch 14, a telescopic guide rod 15 is rotatably sleeved on the column body of the connecting column, and the telescopic end of the telescopic guide rod 15 is fixed to the top end of the ball rod 13;

[0035] By setting the shock component, when the mounting cover 3 and the air intake connector 1 as a whole are shaken up and down by bumps during vehicle operation, the telescopic rod 7 in the shock component can reciprocate and retract in the inner side of the air intake connector 1 to push and pull the movable plate 10, thereby making the telescopic guide rod 15 and the ball rod 13 swing back and forth as a whole, knocking on the inner wall of the dustproof ring plate 4, thereby utilizing the knocking and vibration method to further improve the dust shedding effect on the dustproof ring plate 4.

[0036] Further, refer to Figure 4 As shown, it is worth noting that a scraper 18 is slidably provided on the outer wall of the dust ring plate 4, and the scraper 18 is fixedly connected to the inner wall of the top end of the mounting cover 3 through a bracket;

[0037] By setting the scraper 18, when the knob support 11 is turned to separate the mounting cover 3 from the suction joint 1, the scraper 18 can slide up along the outer wall of the dustproof ring plate 4 at the same time, scraping the dust on the dustproof ring plate 4, thereby achieving the effect of cleaning the outer wall of the dustproof ring plate 4.
