[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] The embodiment of the present invention provides an agricultural machinery instrument, such as Figure 1-10 As shown, it includes an instrument body 1, and a cleaning mechanism is fixedly connected to the top of the instrument body 1. The cleaning mechanism includes an air storage box 5, a blowing pipe 2, a connecting pipe 16, and a switch structure. The air storage box 5 is fixedly connected to the instrument body 1, and the blowing pipe 2 is fixedly connected to the top of the air storage box 5. The blowing pipe 2 is provided with an air outlet 3 on the side facing the instrument body 1, and an air storage space 15 is provided in the air storage box 5. One end of the connecting pipe 16 is connected to the air storage space 15, and the other end of the connecting pipe 16 is connected to the blowing pipe 2, so that the air storage space 15 and the blowing pipe 2 are interconnected. A switch structure for controlling the switch of the connecting pipe 16 is provided on the connecting pipe 16. The air pressure in the air storage space 15 is greater than the atmospheric pressure. When the switch structure is turned on, the gas in the air storage space 15 enters the blowing pipe 2 through the connecting pipe 16 and is blown out from the air outlet 3.

[0034] When there is dust on the instrument body 1, slide the slider 6 along the air storage box 5 to the middle position, so that the first permanent magnet 19 and the second permanent magnet 20 correspond to each other. At this time, the first permanent magnet 19 rises under the action of the magnet attraction, and the block 18 rises to connect the connecting pipe 16. The gas in the air storage space 15 enters the blowing pipe 2 through the connecting pipe 16 and is blown out from the air outlet 3. The air outlet 3 corresponds to the upper surface of the instrument body 1, so that the airflow blown out of the air outlet 3 blows the dust downward along the inclined upper surface of the instrument body 1 into the collecting tank 11, so that the dust on the instrument body 1 can be cleaned quickly, conveniently and in time, and the use effect is good.

[0035] The air blowing pipe 2 covers the upper edge of the instrument body 1 , and a plurality of air outlet holes 3 are provided, and the plurality of air outlet holes 3 are arranged at equal intervals.

[0036] The switch structure includes a slider 6, a first permanent magnet 19, a second permanent magnet 20, a vertical slide groove 17, and a stopper 18.

The top of the stopper 18 is fixedly connected with the first permanent magnet 19. The slider 6 is slidably fitted on the top of the air storage box 5. The second permanent magnet 20 is embedded in the slider 6. The first permanent magnet 19 and the second permanent magnet 20 are mutually attractive magnets, and when the slider 6 slides to the middle of the air storage box 5, the first permanent magnet 19 and the second permanent magnet 20 correspond to each other. Under normal circumstances, the stopper 18 is at the bottom of the vertical slide groove 17 under the action of gravity. At this time, the stopper 18 completely blocks the connecting pipe 16. When the first permanent magnet 19 and the second permanent magnet 20 correspond to each other, the first permanent magnet 19 rises under the action of the magnets attracting each other, and the rise of the stopper 18 makes the connecting pipe 16 connected.

[0037] A collecting assembly 4 for collecting dust is provided below the meter body 1, and the collecting assembly 4 includes a mounting plate 12, a collecting trough 11, an insertion rod 13, and a socket 14. The mounting plate 12 is fixedly connected to the meter body 1, a collecting trough 11 is provided above the mounting plate 12, an insertion rod 13 is fixedly connected to the collecting trough 11, a socket 14 matching the insertion rod 13 is provided on the mounting plate 12, and the collecting trough 11 is detachably connected to the mounting plate 12 via the insertion rod 13.

[0038] A plurality of the inserting rods 13 are provided, and the plurality of the inserting rods 13 are symmetrically arranged on both sides of the collecting tank 11 .

[0039] The agricultural machine also includes an inflation mechanism for automatically inflating the air storage space 15 when the agricultural machine is working. The inflation mechanism includes a base 8, an inflation tube 7, a socket 9, a slot 26, a third permanent magnet 24, a fourth permanent magnet 25, a cylinder 10, an air inlet 22, an air outlet 23, a first one-way valve 27, a second one-way valve 28, a spring 29, a piston plate 30, and a pinball 31. The top of the base 8 is fixedly connected with the socket 9, and the top of the socket 9 is provided with a slot 26 matching the cylinder 10, and the cylinder 10 is inserted into the slot. 26, a third permanent magnet 24 is fixedly connected to the bottom of the cylinder 10, a fourth permanent magnet 25 corresponding to the third permanent magnet 24 is fixedly connected to the socket 9, and the third permanent magnet 24 and the fourth permanent magnet 25 are mutually attractive magnets, an air inlet 22 is opened on the side of the cylinder 10, an air outlet 23 is opened at the bottom of the cylinder 10, a first one-way valve 27 is fixedly connected to the air inlet 22, a second one-way valve 28 is fixedly connected to the air outlet 23, and the inflation tube 7 is set as a hose, and the inflation tube 7 is coiled at the bottom In the seat 8, one end of the inflation tube 7 is fixedly connected to the air storage box 5, and the other end of the inflation tube 7 is fixedly connected to the air outlet 23. The piston in the cylinder 10 is matched with a piston plate 30, the top of the spring 29 is fixedly connected to the piston plate 30, and the bottom of the spring 29 is fixedly connected to the bottom of the cylinder 10. A pinball 31 is movably arranged above the piston plate 30. When the agricultural machine is working in the field, the bumps caused by the terrain and the vibration of the agricultural machine itself cause the pinball 31 to continuously jump up and down above the piston plate 30. When the ball 31 falls, the pinball 31 hits the piston plate 30, causing the piston plate 30 to fall, so that the gas in the cylinder 10 is pressed into the air storage space 15 through the inflation tube 7, and then the pinball 31 contacts the piston plate 30 and bounces up. At the same time, the piston plate 30 is reset under the action of the spring 29, and the piston plate 30 rises, allowing outside air to enter the cylinder 10 through the air inlet 22. Then, as the pinball 31 continues to fall and bounce, the air storage space 15 is inflated in small amounts and multiple times, causing the air pressure in the air storage space 15 to rise.

[0040] When the agricultural machinery is working in the field or driving on a muddy road, the terrain is very bumpy when driving, so that the pinball 31 keeps jumping up and down above the piston plate 30. When the pinball 31 falls, the pinball 31 hits the piston plate 30, causing the piston plate 30 to drop, so that the gas in the cylinder 10 is pressed into the air storage space 15 through the inflation pipe 7. Then the pinball 31 contacts the piston plate 30 and bounces up. At the same time, the piston plate 30 is reset under the action of the spring 29. The piston plate 30 rises, allowing outside air to enter the cylinder 10 through the air inlet 22. Then, as the pinball 31 keeps falling and bouncing up, the air storage space 15 is inflated in small amounts multiple times, so that the air pressure in the air storage space 15 rises. Therefore, after each long period of work, the air pressure in the air storage space 15 will be restored to a pressure that can clean the dust. Therefore, the working environment of the agricultural machinery can be used to ensure that the air pressure in the air storage space 15 can be automatically restored, which is convenient for cleaning after each work is completed.

[0041] The arrangement of the third permanent magnet 24 and the fourth permanent magnet 25 can ensure that the cylinder 10 will not fall out due to bumps when inserted into the slot 26, and also facilitates the cylinder 10 to be quickly picked up when manually cranked.

[0042] The top of the base 8 is fixedly connected to a top plate 21, the socket 9 is fixedly connected to the top of the top plate 21, a first through hole for the inflation tube 7 to pass through is opened in the center of the top plate 21 and the socket 9, and a second through hole for the inflation tube 7 to pass through is opened on the side of the base 8.

[0043] When the air pressure in the air storage space 15 is insufficient, the cylinder 10 can be manually grasped and pulled out from the socket 9, and then manually shaken up and down, so that air can be pumped into the air storage space 15, which is convenient for manually inflating the air storage space 15 when the agricultural machinery is not used for a long time.

[0044] The height position of the air inlet hole 22 is set between the upper surface of the socket 9 and the lower surface of the piston plate 30 .

[0045] The top of the piston plate 30 is fixedly connected with an elastic plate, and the top of the cylinder 10 is fixedly connected with a buffer plate 32, which is made of a buffer material. The buffer plate 32 is used to prevent the cylinder 10 from being damaged due to excessive force during hand-cranking.

[0046] The buffer plate 32 and the top of the cylinder 10 are both provided with ventilation holes.

[0047] Working principle: When there is dust on the instrument body 1, slide the slider 6 along the air storage box 5 to the middle position, so that the first permanent magnet 19 and the second permanent magnet 20 correspond to each other. At this time, the first permanent magnet 19 rises under the action of the magnet attraction, and the block 18 rises to connect the connecting pipe 16. The gas in the air storage space 15 enters the blowing pipe 2 through the connecting pipe 16 and is blown out from the air outlet 3. The air outlet 3 corresponds to the upper surface of the instrument body 1, so that the airflow blown out from the air outlet 3 blows the dust downward along the inclined upper surface of the instrument body 1 into the collecting tank 11, so that the dust on the instrument body 1 can be cleaned quickly, conveniently and in time, and the use effect is good.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
