[0038] The spray horizontal bracket 21 includes a front horizontal bracket 21a and a rear horizontal bracket 21b which are arranged opposite to each other, and the opposite sides of the front horizontal bracket 21a and the rear horizontal bracket 21b are provided with a clamping groove clamped on the spray longitudinal bracket 15, and the opposite sides of the front horizontal bracket 21a and the rear horizontal bracket 21b are provided with mounting flanges at both ends of the clamping groove, and the mounting flanges are provided with mounting holes for bolt installation, so that the front horizontal bracket and the rear horizontal bracket can be clamped outside the spray longitudinal bracket, and the spray longitudinal bracket 15 is provided with a platform 15a for preventing the spray horizontal bracket 21 from sliding down. Preferably, the spray longitudinal bracket 15 adopts a telescopic rod structure, which is convenient for adjusting the height of the spray assembly and is suitable for spraying different crops.

[0039] In order to ensure that the spray can be sprayed on the back of the blade and to facilitate spraying crops at different heights, a guide cover 27 is provided at one end of the spray barrel 18, and the atomizing nozzle 16 is located in the guide cover 27. A fan 28 is installed at the other end of the spray barrel 18, and the fan is electrically connected to the control center. The guide cover adopts a conical cover. At the same time, the setting of the guide cover and the fan also enables the spray to be quickly sprayed to the corresponding position during spraying to prevent interference wind from blowing away. Preferably, the fan adopts an axial flow fan.

[0040] To facilitate determination of the spraying height and distance as well as the cutting height and distance, a laser radar 29 for monitoring the distance and height between the equipment and the crop to be processed is provided in both the spraying module C and the cutting module B, and the laser radar 29 is electrically connected to the control center. Specifically, the laser radar is provided on the corresponding longitudinal bracket. Preferably, a monitoring device electrically connected to the control center is also provided in the mowing module to facilitate determination of the working range.

[0041] Since both the cutting module and the spraying module are provided with longitudinal brackets, in order to increase the working range, a rotating assembly for realizing the rotation of the cutting module B or the spraying module C is provided on the mounting bracket. The rotating assembly includes a rotating motor 12 electrically connected to the control center. A conversion mechanism 13 is provided at the output end of the rotating motor 12. An installation base plate 14 for installing the cutting module or the spraying module is provided on the conversion mechanism 13. That is, the lower ends of the cutting longitudinal bracket and the spraying longitudinal bracket are both installed on the installation base plate.

[0042] The conversion mechanism 13 includes a driving gear arranged outside the output end of the rotating motor and a conversion seat arranged on the mounting bracket. A rotating shaft is arranged in the conversion seat through a bearing, and a driven gear capable of meshing with the driving gear is arranged at the lower end of the rotating shaft. A protective cover is sleeved outside the driving gear. Notches are provided at the positions where the protective cover and the conversion seat correspond to the gear meshing. The installation base plate is arranged at the upper end of the rotating shaft. When the rotating motor works, the rotation of the installation base plate can be realized through the meshing of the gears, so as to realize the rotation of the longitudinal bracket installed on the installation base plate, and further expand the working range of the cutting module and the spraying module.

[0043] To make the mounting bracket suitable for the installation of different modules, the mounting bracket is set as a rectangular frame. The rear end of the rectangular frame can be used as the space for installing the control panel or the space for placing items. A placement space for placing the medicine box is provided in the middle of the mounting bracket. An installation space for a plunger pump capable of pumping the liquid in the medicine box is provided at a position near the front end of the mounting bracket. To prevent the medicine box from slipping, a U-shaped baffle is provided in the middle of the placement space on either the left or the right side. At the same time, a fixed clamping ring 19 which is also set as U-shaped and can be installed on the baffle is equipped. Installation flanges capable of being installed on the baffle are provided at both ends of the fixed clamping ring.

[0044] To facilitate the installation of the rotating motor, installation frames for installing the rotating motor are provided on both the left and right sides at the front end of the mounting bracket. That is, the installation frames are located above the traveling mechanism, and installation columns are provided on the side of the bottom surface of the installation frame close to the mounting bracket. Preferably, the loading module also adopts a rectangular frame, and a fixed flanging is provided at the lower end of the loading module. Correspondingly, an installation ear 2a in the shape of 7 is provided at the upper end of the mounting bracket for facilitating the installation of the loading module.

[0045] When cutting is required, the cutting longitudinal bracket is installed on the mounting base plate by bolts and nuts. Taking mowing as an example, the cutting module is explained: when working, the laser radar and the monitoring equipment work together, and transmit the information received to the control center. The control center determines whether the range of work and the cutting place are in a horizontal state based on the information obtained, and converts the corresponding information into a corresponding component working time signal, and transmits the signal to the corresponding component to make the corresponding component work. In this application, the cutting module can achieve cutting on the front side of the walking mechanism and the left and right sides of the walking mechanism by adjusting the rotating motor, and can also achieve horizontal cutting and cutting with a certain slope.

[0046] When it is necessary to spray water, fertilizer or pesticide, the spray longitudinal bracket is installed on the mounting base plate through bolts and nuts, and one end of the atomizing nozzle is facing the left and right sides. Taking the spraying of pesticides as an example, the equipment is explained: when working, the laser radar and the monitoring equipment work together, and transmit the received information to the control center. The control center judges the distance between the spraying equipment and the center of the crown, the crown density and the pest and disease situation based on the information obtained, and converts the corresponding information into the corresponding component working time signal, and transmits the signal to the corresponding component to make the corresponding component work, that is, first make the rotating motor rotate the corresponding angle, the tilting motor rotate the moving angle, and then open the solenoid valve, and at the same time, the pump and fan connected to the medicine box start working, and the liquid in the medicine box is sprayed out by the atomizing nozzle. Under the action of the fan, the liquid is blown to the target position accurately and efficiently. When it is detected that the crown density is large or the pest and disease are serious, it is necessary to increase the wind force and air volume output by the fan.

[0047] When installing the loading module, the fixed flange of the loading module is slid in along the mounting ears and then fixed by bolts. At the same time, since the mounting bracket adopts a rectangular frame, the mounting bracket can also be used for transporting objects.
