[0029] In the embodiment of the utility model, the annular baffle 11 and the fixed support legs 111 are arranged so that the hydraulic motor 13 can be stably installed in the dustproof box 1, while maximally reducing its wind resistance so that the internal air can flow smoothly and then be discharged to the outside through the exhaust groove 12.

[0030] In the embodiment of the present invention, the setting of the outer dustproof net 123 can prevent external dust from entering the exhaust groove 12, thereby preventing dust from accumulating on the main shaft of the hydraulic motor 13, thereby preventing dust from affecting the operation of the hydraulic motor 13. Secondly, the setting of the inner dustproof net 122 can block dust for a second time to prevent it from entering the dustproof box 1, thereby ensuring the service life of the device and preventing dust from accumulating inside the device and affecting the service life of the device.

[0031] In the embodiment of the present invention, by utilizing the air flow at the main shaft of the hydraulic motor 13, when the main shaft of the hydraulic motor 13 is rotating during use, the air flow can be utilized to blow away dust from the main shaft of the hydraulic motor 13, thereby avoiding dust accumulation on the main shaft and ensuring the service life of the hydraulic motor 13.

[0032] The transmission shaft 14 is located at the lower part of the dustproof box 1 and is installed in the dustproof box 1 through a bearing seat and a bearing. A small pulley 141 is installed at one end of the transmission shaft 14, and a transmission belt 142 is installed between the small pulley 141 and the large pulley 131. A transmission gear 143 is installed at the other end of the transmission gear 143. An acceleration gear 144 is provided on one side of the transmission gear 143, and the acceleration gear 144 is meshed with the transmission gear 143; the exhaust groove 15 is opened at the center of the surface of the other side of the dustproof box 1, and a dust filter element 151 is installed on the inside and outside of the dustproof box 1, and a secondary filter screen 152 is provided on one side of the dust filter element 151; the exhaust fan 16 is installed inside the dustproof box 1, and its exhaust port is inserted in the exhaust groove 15, and a small gear 161 is installed at its input end, and the small gear 161 is meshed with the acceleration gear 144.

[0033] In the embodiment of the utility model, the transmission of the transmission shaft 14 is utilized to enable the hydraulic motor 13 to operate, thereby driving the exhaust fan 16 to rotate, and the acceleration effect of the acceleration gear 144 is utilized to increase the rotation speed of the exhaust fan 16, thereby enabling the outside air to be quickly drawn into the dustproof box 1, thereby rapidly increasing the amount of air inside the box, thereby ensuring the rapid flow of air, improving the cooling efficiency of the hydraulic motor 13, and the dustproof effect of the device.

[0034] The folded delivery pipe 2 is installed at the oil inlet and oil outlet of the hydraulic motor 13, and one end extends out of the dustproof box 1 and is connected to the dustproof box 1 through a sealing seat 21. An extrusion cushion 21 is provided on the sealing seat 21, and a sealing sleeve 22 is threadedly installed on the sealing seat 21. An insertion port 221 is opened at the upper end of the sealing sleeve 22, and an elastic sealing sleeve 222 is provided inside the sealing sleeve 22.

[0035] In the embodiment of the present invention, the arrangement of the folded delivery pipe 2 can enable the hydraulic oil inlet pipe and outlet pipe of the hydraulic motor 13 to be spaced a certain distance apart, thereby providing workers with more space when installing the hydraulic oil pipe, making it easier for workers to install the hydraulic oil pipe.

[0036] In the embodiment of the present invention, the threaded connection between the sealing seat 21 and the sealing sleeve 22 is utilized, and the sealing is performed by squeezing the soft pad 211, so that the connection between the folding delivery pipe 2 and the hydraulic oil pipe can be sealed in a closed space, thereby preventing excessive dust from accumulating at the interface of the hydraulic motor 13 when it is used for a long time, thereby preventing dust from flowing into the hydraulic motor 13 through its interface.

[0037] In the embodiment of the present invention, the elastic sealing sleeve 222 can be stretched out to be put on the hydraulic oil pipe by utilizing its elasticity, and its elasticity can be used to keep it tight with the hydraulic oil pipe. At the same time, the sealing sleeve 22 can be put on the elastic sealing sleeve 222 to isolate the connection between the hydraulic oil pipe and the folded delivery pipe 2 from the outside world, thereby ensuring the airtightness of the hydraulic oil pipe connection and isolating it from dust.

[0038] In the present invention, when the exhaust fan blades 132 rotate, the air inside the exhaust groove 12 flows to the outside of the dustproof box 1; the dust in the exhaust groove 12 can be blown to the outside of the dustproof box 1, avoiding dust accumulation on the main shaft of the hydraulic motor 13, thereby ensuring the service life of the hydraulic motor 13.

[0039] In the present invention, the acceleration gear 144 is installed in the dustproof box 1 through the acceleration gear shaft and the bearing, ensuring smooth transmission of the acceleration gear 144.

[0040] In the present invention, the sealing sleeve 22 and the elastic sealing sleeve 222 are sleeved on the hydraulic oil pipe, and the sealing sleeve 22 and the hydraulic oil pipe are sealed by the elastic sealing sleeve 222 to ensure the sealing of the connection between the hydraulic oil pipe and the folded delivery pipe 2.

[0041] In the utility model, the folded delivery pipe 2 is quickly connected to the external hydraulic oil pipe through a quick connector, which facilitates the rapid connection of the hydraulic oil pipe.

[0042] In the present invention, the diameter of the insertion port 221 is larger than the outer diameter of the quick connector on the hydraulic oil pipe and smaller than the outer diameter of the elastic sealing sleeve 222; this facilitates the installation of the elastic sealing sleeve 222 and the sealing sleeve 22 on the hydraulic oil pipe.

[0043] When using the present invention specifically, the staff installs the dustproof box 1 on the agricultural machinery, and then puts the sealing sleeve 22 on the hydraulic oil pipe. Then the elastic sealing sleeve 222 is stretched and put on the hydraulic oil pipe, and then the hydraulic oil pipe is respectively connected to the two folded delivery pipes 2. Then the staff installs the sealing sleeve 22 on the sealing seat 21, and then uses extrusion to seal the sealing seat 21 and the sealing sleeve 22. At the same time, the sealing sleeve 22 and the hydraulic oil pipe are sealed by the elastic sealing sleeve 222.

[0044] When the hydraulic motor 13 starts to work, its output shaft drives the large pulley 131 to rotate, and drives the small pulley 141 to rotate through the transmission belt 142, so that the transmission shaft 14 drives the transmission gear 143 to rotate, and the small gear 161 drives the exhaust fan 16 to rotate through the transmission of the acceleration gear 144;

[0045] The exhaust fan 16 utilizes the acceleration effect of the entire transmission mechanism to rotate at a high speed, and the high-speed rotation of the exhaust fan 16 causes the exhaust end to start exhausting air, and the external air is sucked into the exhaust groove 15 by the suction force of the exhaust fan 16, and is filtered by the dust filter element 151 to remove dust in the air, so that the clean air passes through the secondary filter 152 and enters the exhaust fan 16, and then the clean air is injected into the dustproof box 1 by the operation of the exhaust fan 16;

[0046] At the same time, the hydraulic aunt 13 drives the exhaust fan blades 132 to start rotating, so that the air inside the exhaust groove 12 is discharged to the outside 1 of the dustproof box, and the exhaust fan 16 is used to continuously inject clean air into the dustproof box 1, so that the air is pushed by the air pressure to pass through the exhaust hole 121 into the exhaust groove 12, and the air is quickly discharged through the rotation of the exhaust fan blades 132;

[0047] The flow of air in the dustproof box 1 can be used to assist in dissipating heat for the hydraulic motor 13 and reduce its temperature. At the same time, the flow of air can be used to keep the output shaft of the hydraulic motor 13 clean and avoid dust accumulation, thereby increasing the service life of the hydraulic motor 13.

[0048] During the specific implementation of the present invention, the secondary filter 152 can be used to ensure the dustproofness of the exhaust groove 15 when the dust filter element 151 is disassembled, thereby preventing external dust from entering the dustproof box 1.
