[0023] Reference Figure 1-3 The utility model provides an anti-collision device for farming machinery operation, comprising:

[0024] A mounting plate 1, the mounting plate 1 is used to be mounted on a tillage machine;

[0025] The first buffer assembly includes two cylinder bodies 2, which are symmetrically fixedly connected to the mounting plate 1, and a piston 3 is movably connected in the cylinder body 2. The cylinder body 2 and the piston 3 are filled with gas, and a top cap 4 is fixedly connected to the piston 3. The top cap 4 is clamped on the cylinder body 2, and a deflation mechanism is provided on the cylinder body 2. A push rod 5 is fixedly connected to the piston 3, and the push rod 5 is correspondingly arranged with the deflation mechanism;

[0026] The second buffer assembly includes a frame 6, both ends of the frame 6 are fixedly connected to the top cap 4, two moving rods 7 are elastically provided on the frame 6, the two moving rods 7 are fixedly connected to an outer plate 8, and the outer plate 8 is fixedly connected to an arc plate 9.

[0027] In this device, the mounting plate 1 is used to connect with the tillage machinery, the cylinder body 2 is filled with gas, the piston 3 is in the cylinder body 2, and can be used as a buffer when squeezed, the top cap 4 is used to connect with the frame 6, when the external impact force is large, the piston 3 moves a long distance in the cylinder body 2, the push rod 5 will trigger the deflation mechanism, thereby deflation of the cylinder body 2, and the deflation of the cylinder body 2 will gradually release the impact force, the arc plate 9 is in the outermost layer, the arc plate 9 contacts with the external object, if the impact force is large, the arc plate 9 can be deformed to absorb part of the impact force, and the arc plate 9 contacts with the external object to cause the moving rod 7 to move inward, and the moving rod 7 moves on the frame 6, which will drive the frame 6 to move, thereby driving the top cap 4 to move.

[0028] A further optimized solution is that a first electrode sheet 10 is fixedly connected to the moving rod 7, a second electrode sheet 11 is fixedly connected to the top cap 4, the first electrode sheet 10 and the second electrode sheet 11 are arranged correspondingly, a warning light is connected in series with the first electrode sheet 10 and the second electrode sheet 11, and the warning light is electrically connected to a power source.

[0029] After the moving rod 7 moves a certain distance, the first electrode sheet 10 will contact the second electrode sheet 11, so that the warning light (not shown in the figure) and the power supply (not shown in the figure) form a connected circuit, so that the warning light (not shown in the figure) lights up, and the warning light (not shown in the figure) is in a position that is easy for the driver to see.

[0030] A further optimized solution is provided, in which the air release mechanism includes a plugging cover 12, an exhaust hole is provided on the cylinder body 2, the plugging cover 12 is blocked in the exhaust hole, a first cavity 13 is provided in the cylinder body 2, a first limiting plate 14 is placed in the first cavity 13, the first cavity 13 is connected with the exhaust hole, a groove is provided on the plugging cover 12, the first limiting plate 14 is inserted into the groove, a first spring 15 is placed in the first cavity 13, the first spring 15 abuts against the first limiting plate 14, a first through hole is provided on the cylinder body 2, the first through hole is connected with the first cavity 13, a first straight rod 16 is fixedly connected to the first limiting plate 14, and the first straight rod 16 is arranged corresponding to the push rod 5.

[0031] The blocking cover 12 blocks the exhaust hole. When the top cap 4 moves a large distance, the push rod 5 will contact the first straight rod 16, and the first straight rod 16 will move. The first straight rod 16 drives the first limit plate 14 to move, and the first limit plate 14 will leave the groove of the blocking cover 12. At this time, the air pressure in the cylinder body 2 is relatively high, which will flush the blocking cover 12 out of the exhaust hole, thereby causing the gas in the cylinder body 2 to leak and slowly release the impact force. In the non-impact state, the first spring 15 will keep the first limit plate 14 inserted into the groove.

[0032] A further optimized solution is that the frame 6 includes a cross bar 17 and two second straight bars 18, the cross bar 17 is fixedly connected between the two second straight bars 18, the two second straight bars 18 are fixedly connected to the top cap 4, a second cavity 19 is opened in the second straight bar 18, a movable block 20 is placed in the second cavity 19, a second through hole 21 is opened on the second straight bar 18, the second through hole 21 is connected to the second cavity 19, a connecting rod 22 is fixedly connected to the movable block 20, the connecting rod 22 extends out of the second through hole 21, the connecting rod 22 is fixedly connected to the moving rod 7, a second spring 23 is placed in the second cavity 19, and the second spring 23 abuts against the movable block 20.

[0033] Under the action of the second spring 23, the movable block 20 is on the side away from the second electrode sheet 11. When the movable rod 7 moves, the movable rod 7 drives the connecting rod 22 and the movable block 20 to move. When the impact force is large, the movable rod 7 causes the first electrode sheet 10 to contact the second electrode sheet 11.

[0034] According to a further optimized solution, a third through hole is provided on the cross bar 17 , a guide tube 24 is fixedly connected to the third through hole, the moving rod 7 is passed through the guide tube 24 , and the moving rod 7 is slidably arranged in the guide tube 24 .

[0035] The moving rod 7 moves in the guide tube 24 .

[0036] According to a further optimization scheme, a first baffle ring 25 is fixedly connected to the cylinder body 2 , and a second baffle ring 26 is fixedly connected to the top cap 4 . The first baffle ring 25 is located inside the top cap 4 , and the inner ring size of the first baffle ring 25 is smaller than the outer ring size of the second baffle ring 26 .

[0037] When the cylinder 2 is filled with gas, the first stop ring 25 and the second stop ring 26 abut against each other to prevent the piston 3 from separating from the cylinder 2 .

[0038] According to a further optimized solution, a gas nozzle 27 is installed on the cylinder body 2 .

[0039] Gas is charged into the cylinder 2 through the gas nozzle 27 .

[0040] The working principle of this device is that when the tillage machinery collides with an obstacle, the arc plate 9 is in the outermost layer, and the arc plate 9 first contacts the external object, and the arc plate 9 drives the moving rod 7 to move inward. After the moving rod 7 moves a certain distance, the first electrode sheet 10 will contact the second electrode sheet 11, so that the warning light and the power supply form a connected circuit, so that the warning light is on, and the driver notices that the obstacle has been hit. If the impact force is large, the arc plate 9 can be deformed to absorb part of the impact force first, and at the same time, the top cap 4 drives the piston 3 to squeeze the gas in the cylinder body 2. When the top cap 4 moves a large distance, the push rod 5 will contact the first straight rod 16, and the first straight rod 16 will move. The first straight rod 16 drives the first limit plate 14 to move, and the first limit plate 14 will leave the groove of the blocking cover 12. At this time, the air pressure in the cylinder body 2 is high, and the blocking cover 12 will be flushed out of the exhaust hole, so that the gas in the cylinder body 2 leaks and the impact force can be slowly released.
