If the positions of the two walking frames are skewed, the photoelectric sensor on one side cannot normally irradiate the position of the receiver. At this time, the signal of the photoelectric sensor is abnormal, and a signal can be sent in time to prompt, avoiding damage to the device caused by the unbalanced walking of the walking frames on both sides, and thus improving the stability of the device operation.

[0023] The usage steps of the present invention are as follows. When the large-span multi-functional agricultural machinery and equipment is in use, through the cooperation of the driving frame 103 and the driving wheel 104, it can provide support for the two walking frames 101. By rotating the driving wheel 104, the two walking frames 101 can be driven to walk above the farmland for operation. Through the operation of the motor 207, the sliding seat 201 can be driven to displace. The sliding seat 201 can cover the farmland below the walking frame 101 for operation. When the sliding seat 201 displaces, it will drive the side seat 210, the insertion rod 211 and the piston 212 to displace accordingly. At this time, the piston 212 will slide on the inner wall of the sleeve 303. When the piston 212 moves outward, the displacement of the piston 212 is used to reduce the air pressure inside the sleeve 303. At this time, the one-way valve 304 will be in a connected state, and the connected state of the one-way valve 304 is for the external to flow into the sleeve 303. Therefore, at this time, as the piston 212 displaces, air will be pumped into the sleeve 303. When the sliding seat 201 displaces in the reverse direction, it will drive the piston 212 to displace into the sleeve 303. At this time, the piston 212 compresses the air inside the sleeve 303. When the air is compressed, the one-way valve 304 will be in a closed state. At this time, due to the increase in the air pressure inside the sleeve 303, pressure will be exerted on the baffle 309. After being pressured, the baffle 309 will move outward, and at the same time, the compression spring 310 will contract. When the baffle 309 moves outward, the conical tube 305 will be in a connected and bridged state. At this time, the compressed air inside the sleeve 303 will enter the air storage tank 302 through the connection of the connecting pipe 306. The air storage tank 302 can store the compressed gas. At this time, along with the kinetic energy of the operation of the motor 207 driving the sliding seat 201 to adjust the working position, the compressed air can be collected into the air storage tank 302. When it is necessary to control the spraying operation on the crops below from the position of the nozzle 203, the solenoid valve at the position of the double-pass pipe 307 is opened. At this time, the high-pressure gas stored inside the air storage tank 302 will enter the two liquid storage tanks 105 respectively through the connection of the double-pass pipe 307 and the hose. Since the liquid storage tanks 105 store the liquid for spraying, when high-pressure gas is introduced into the liquid storage tanks 105, the liquid inside the liquid storage tanks 105 will be pressured to flow along the passage. The liquid will enter the second corrugated pipe 205 through the connection of the connecting pipe 110, and then the liquid will flow through the input pipe 204 and the connecting seat 202, and then the liquid will be sprayed downward from the nozzle 203 position, completing the spraying operation on the crops below. Through the setting that the sliding seat 201 can use kinetic energy to store high-pressure gas in the air storage tank 302, and the high-pressure gas stored in the air storage tank 302 can be used for liquid transportation, the purpose of saving the installation cost of the driving equipment can be achieved. At the same time, through the utilization of kinetic energy, the energy consumption can be reduced, realizing the purpose of energy conservation and emission reduction.

[0024] Embodiment 2: As Figure 1 、 Figure 2, Figure 8 and Figure 9 As shown in Figure 8 and Figure 9 , the fixed seat 402 is fixedly connected to one of the walking frames 101, and the slide rails 401 and the mounting seat 404 are fixedly connected to the other walking frame 101. The outer surfaces of the two slide rails 401 are both slidably connected with sliders 403, and the sliders 403 are fixedly connected to the fixed seat 402. On the outer surface of the mounting seat 404 close to the fixed seat 402, an electric push rod 405 is fixedly connected, and the electric push rod 405 is fixedly connected to the fixed seat 402.

[0025] The usage steps of the present invention are as follows: When the agricultural machinery equipment is put into use, according to the range of crops to be covered, the distance between the two walking frames 101 can be adjusted, so as to achieve the purpose of adapting to cover crops with different spans. Starting the electric push rod 405 to extend can drive the displacement of the fixed seat 402. When the fixed seat 402 is displaced, it can drive one side of the walking frame 101 to follow the displacement, thus achieving the purpose of adjusting the distance between the two walking frames 101. Through the cooperation setting of the slider 403 and the slide rail 401, it plays a role in supporting and limiting the displacement of the fixed seat 402 and the two walking frames 101. When the distance between the two walking frames 101 is adjusted by displacement, referring to Figure 2 As shown in Figure 2 , when the distance between the tooth plate 112 and the limiting rod 111 is not enlarged, they are both in a state of extending to the outside. Therefore, after the distance between the two walking frames 101 is adjusted, the displacement range of the sliding seat 201 can also be enlarged, so that the sliding seat 201 can adapt to the position adjustment of the walking frame 101 and complete the operation for crops with different spans, effectively improving the functionality of the device.

[0026] Embodiment 3: As shown in Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown in Figure 1 , Figure 2 , Figure 8 and Figure 9 , on the outer surface of the mounting seat 404 close to the fixed seat 402, an opposed sensor 406 is fixedly connected, and on the outer surface of the fixed seat 402 close to the mounting seat 404, a receiver 407 is fixedly connected. The opposed sensor 406 and the receiver 407 are provided in a matching manner.

[0027] In the operation steps of the present invention, when adjusting the position of the fixed seat 402 through the operation of the electric push rod 405, the horizontal state of the two side walking frames 101 can be corrected by the combined use of the through-beam sensor 406 and the receiver 407. When the two walking frames 101 are in a horizontal state, the infrared signal emitted by the through-beam sensor 406 can accurately irradiate the position of the receiver 407, indicating that the position of the walking frame 101 is relatively stable. If the positions of the two walking frames 101 are skewed, the through-beam sensor 406 on one side cannot normally irradiate the position of the receiver 407. At this time, the through-beam signal of the through-beam sensor 406 is abnormal, and a signal can be timely sent for prompt, avoiding damage to the device caused by the unbalanced walking of the two side walking frames 101, thereby improving the stability of the device operation.

[0028] The effects and working principle achieved by the entire mechanism are as follows: When the large-span multi-functional agricultural machinery and equipment is in use, through the coordinated use of the drive frame 103 and the drive wheel 104, it can provide support for the two walking frames 101. After connecting the drive structure at the position of the drive frame 103, it can drive the drive wheel 104 to rotate. Through the rotation of the drive wheel 104, the two walking frames 101 can be driven to walk above the farmland for operation. While the walking frames 101 are walking for operation, a large-span farmland is covered below the two walking frames 101. Through the operation of the motor 207, the sliding seat 201 can be driven to displace. The sliding seat 201 can cover the farmland below the walking frame 101 for operation. After the motor 207 operates, the rotating shaft 208 can be driven to rotate. Through the rotation of the rotating shaft 208, the gear 209 can be driven to rotate. When the gear 209 rotates, it can drive the sliding seat 201 to displace by meshing with the toothed plate 112. The setting of the limiting rod 111 can play a role in supporting and limiting the displacement of the sliding seat 201. When the sliding seat 201 displaces, it can drive the connecting seat 202, the nozzle 203, the input pipe 204, and the second corrugated pipe 205 to displace accordingly. Through the connection of the second corrugated pipe 205, the input pipe 204 can always be kept in a connected state with the connecting pipe 110. While the sliding seat 201 is moving, it will also drive the side seat 210, the insertion rod 211, and the piston 212 to displace accordingly. At this time, the piston 212 will slide on the inner wall of the sleeve 303. When the piston 212 moves outward, the displacement of the piston 212 is used to reduce the air pressure inside the sleeve 303. At this time, the one-way valve 304 will be in a connected state. The connected state of the one-way valve 304 is for the external air to flow into the sleeve 303. Therefore, at this time, as the piston 212 displaces, air will be pumped into the sleeve 303. When the sliding seat 201 displaces in the reverse direction, it will drive the piston 212 to displace into the sleeve 303. At this time, the piston 212 compresses the air inside the sleeve 303. When the air is compressed, the one-way valve 304 will be in a closed state. At this time, due to the increase in the air pressure inside the sleeve 303, pressure will be exerted on the baffle 309. After being pressed, the baffle 309 will move outward, and at the same time, the spring 310 will be compressed. When the baffle 309 moves outward, the conical tube 305 will be in a connected and bridged state. At this time, the compressed air inside the sleeve 303 will enter the air storage tank 302 through the connection of the connecting pipe 306. The compressed gas can be stored in the air storage tank 302. At this time, the kinetic energy of the sliding seat 201 can be adjusted with the operation of the motor 207, and the compressed air can be collected into the air storage tank 302. When the device is put into use, a certain amount of compressed gas is injected into the air storage tank 302 for use in the initial stage of the device operation. When the compressed air stored in the air storage tank 302 is utilized, two hoses at the position of the double-pass pipe 307 are used to connect the two intake pipes 106. Solenoid valves are respectively installed inside the two passages of the double-pass pipe 307 to control the passages of the double-pass pipe 307.When it is necessary to control the spraying operation on the crops below from the position of the nozzle 203, the solenoid valve at the position of the double-pass pipe 307 is opened. At this time, the high-pressure gas stored inside the air storage tank 302 will enter the two liquid storage tanks 105 respectively through the connection of the double-pass pipe 307 and the hose. Since the liquid for spraying is stored in the liquid storage tank 105, when high-pressure gas is introduced into the liquid storage tank 105, the liquid in the liquid storage tank 105 will be under pressure and flow along the passage. At this time, the liquid will enter the second corrugated pipe 205 through the connection of the connecting pipe 110, and then the liquid will flow through the input pipe 204 and the connecting seat 202, and then the liquid will be sprayed downward from the nozzle 203 position, completing the spraying operation on the crops below. By using the kinetic energy to store high-pressure gas in the air storage tank 302 when the sliding seat 201 moves, and the high-pressure gas stored in the air storage tank 302 can be used for liquid transportation, the purpose of saving the installation cost of the driving equipment can be achieved. At the same time, by using the kinetic energy, the energy consumption can be reduced, achieving the purpose of energy conservation and emission reduction. When the agricultural machinery equipment is put into use, according to the range of crops to be covered, the distance between the two walking frames 101 on both sides can be adjusted, so as to achieve the purpose of adapting to cover crops with different spans. Starting the electric push rod 405 to extend can drive the fixed seat 402 to move. When the fixed seat 402 moves, it can drive one side of the walking frame 101 to move accordingly, so as to achieve the purpose of adjusting the distance between the two walking frames 101. When the fixed seat 402 moves, the fixed seat 402 will drive the slider 403 to move along the slide rail 401, that is, through the cooperation of the slider 403 and the slide rail 401, it plays a role in supporting and limiting the movement of the fixed seat 402 and the two walking frames 101. When the distance between the two walking frames 101 is adjusted by displacement, refer to, Figure 2 As shown, when the tooth plate 112 and the limit rod 111 are not pulled apart, they are both in a state of extending to the outside. Therefore, after the distance between the two walking frames 101 is adjusted, the displacement range of the sliding seat 201 can also be enlarged, so that the sliding seat 201 can adapt to the position adjustment of the walking frame 101 and complete the operation for crops with different spans, effectively improving the functionality of the device. When adjusting the position of the fixed seat 402 by the operation of the electric push rod 405, through the combined use of the light sensor 406 and the receiver 407, the horizontal state of the two walking frames 101 can be corrected. When the two walking frames 101 are in a horizontal state, the infrared signal emitted by the light sensor 406 can accurately irradiate the receiver 407 position, indicating that the position of the walking frame 101 is relatively stable. If the positions of the two walking frames 101 are skewed, the light sensor 406 on one side cannot normally irradiate the receiver 407 position. At this time, the light sensor 406 has an abnormal light signal and can send a signal prompt in time to avoid damage to the device caused by the unbalanced walking of the two walking frames 101 on both sides, thereby improving the stability of the device operation.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
