[0029] In some embodiments, as shown in Figure 8 The bidirectional delivery assembly 4 also includes a pneumatic cylinder mounting plate 403 mounted on the inner side of the carrying frame 601, a delivery pneumatic cylinder 404 is mounted on the pneumatic cylinder mounting plate 403, a driving plate 405 is connected to the output end of the delivery pneumatic cylinder 404, a linkage rod 406 is fixed between the first delivery part 401 and the second delivery part 402, the driving plate 405 is fixedly connected with the linkage rod 406, and synchronous movement between the first delivery part 401 and the second delivery part 402 can be realized by the delivery pneumatic cylinder 404; the first delivery part 401 does not block the corresponding sealing pipe 204 in the initial state, at this time the medicinal liquid in the corresponding self-flowing drug storage box 3 can flow into the inner cavity of the hollow drug guide cylinder 201 along the drug outlet pipe 302 and the sealing pipe 204, while the second delivery part 402 blocks the corresponding sealing pipe 204, so that the medicinal liquid in the corresponding self-flowing drug storage box 3 cannot flow into the inner cavity of the hollow drug guide cylinder 201 along the drug outlet pipe 302 and the sealing pipe 204, that is, a certain amount of medicinal liquid is stored in the inner cavity of the hollow drug guide cylinder 201 on one side of the first delivery part 401, while there is no medicinal liquid in the inner cavity of the hollow drug guide cylinder 201 on one side of the second delivery part 402.

[0030] When the mobile vehicle body is moved to the first desired spraying position, the prepared pesticide is poured into the self-flowing storage tank 3 on both sides, and a certain amount of pesticide is stored in the hollow guide tube 201 on the first conveying part 401 side, while no pesticide is stored in the hollow guide tube 201 on the second conveying part 402 side. Then, the driving plate 405 is moved to the first conveying part 401 side by controlling the conveying cylinder 404, and the first conveying part 401 gradually pressurizes the pesticide in the hollow guide tube 201 on the corresponding side into the pesticide supply pipe 202 on the position, until the first conveying part 401 completely pressurizes the pesticide in the hollow guide tube 201, and the pesticide in the self-flowing storage tank 3 on the second conveying part 402 side flows into the hollow guide tube 201 through the outlet pipe 302 and the sealing pipe 204 (the structure design of the sealing pipe 204 and the outlet pipe 302 ensures that the amount of pesticide entering the hollow guide tube 201 will not overflow the inner cavity, thereby achieving control of the amount of pesticide), and then the corresponding electromagnetic valve 206 is closed and the air supplier 603 on the first conveying part 401 side is started, air is supplied to the inside of the pesticide supply pipe 202 through the air supply connection pipe 207 to pressurize the pesticide, and then the pesticide enters the first guide pipe 501 and the second guide pipe 502 on the first conveying part 401 side and enters the pesticide spraying disc 503, and is sprayed onto the corresponding crops by the pesticide spraying disc 503.

[0031] Then, the driving plate 405 is moved in the opposite direction by controlling the conveying cylinder 404 to complete the reset (i.e., moving to the second conveying part 402 side, at this time the electromagnetic valve 206 on the first conveying part 401 side is reopened), and in this process, the second conveying part 402 gradually pressurizes the pesticide in the hollow guide tube 201 on the corresponding side into the pesticide supply pipe 202 on the position, until the second conveying part 402 completely pressurizes the pesticide in the hollow guide tube 201, and the pesticide in the self-flowing storage tank 3 on the first conveying part 401 side flows into the hollow guide tube 201 through the outlet pipe 302 and the sealing pipe 204, and then the corresponding electromagnetic valve 206 is closed and the air supplier 603 on the second conveying part 402 side is started, air is supplied to the inside of the pesticide supply pipe 202 through the air supply connection pipe 207 to pressurize the pesticide, and then the pesticide enters the first guide pipe 501 and the second guide pipe 502 on the second conveying part 402 side and enters the pesticide spraying disc 503, and is sprayed onto the corresponding crops by the pesticide spraying disc 503, thereby achieving the spraying of the same type of pesticide or different types of pesticide on crops planted in intercropping, at this time the electromagnetic valve 206 on the second conveying part 402 side is reopened.

[0032] Then the pesticide application equipment is moved to a second required pesticide application position by the agricultural mobile vehicle body again, at this time a certain amount of pesticide solution is stored in the inner cavity of the hollow pesticide guide cylinder 201 on the side of the first conveying part 401 (the first conveying part 401 does not block the corresponding sealing pipe 204), and there is basically no pesticide solution in the inner cavity of the hollow pesticide guide cylinder 201 on the side of the second conveying part 402 (the second conveying part 402 blocks the corresponding sealing pipe 204), and subsequent synchronization pesticide application between different crops in intercropping can be continuously realized in the same way as described above, thereby improving the efficiency of intercropping pesticide application. It should be noted that the amount of pesticide solution flowing into the inner cavity of the hollow pesticide guide cylinder 201 during the movement of the pesticide application equipment driven by the agricultural mobile vehicle body will not overflow from the inner cavity (i.e., only through the extrusion of the first conveying part 401 or the second conveying part 402), which can be controlled by using a corresponding diameter of the pesticide outlet pipe 302. In addition, the amount of pesticide solution flowing into the inner cavity of the hollow pesticide guide cylinder 201 on the left and right sides may differ during the pesticide application process (of course, in order to reduce the difference between the amounts of pesticide solution flowing into the inner cavities of the hollow pesticide guide cylinders 201 on the left and right sides, the diameters of the pesticide outlet pipes 302 corresponding to the hollow pesticide guide cylinders 201 on the left and right sides can be designed to be different to reduce the difference between the amounts of pesticide solution flowing into the inner cavities), but both are within the normal pesticide application amount range and will not have a significant difference in intercropping pesticide application effect, i.e., both can achieve the expected pesticide application effect.
