[0001] The utility model relates to the technical field of agricultural equipment, in particular to a stirring and spraying fungicide mechanism matched with a wheeled tractor. Background Art

[0002] With the development of agricultural technology, the application of various microbial agents is becoming more and more extensive. For example, a straw degradation agent spraying device is disclosed in the Chinese utility model patent with the authorization announcement number CN217989702U. The device includes a box, a spraying mechanism and an external fixing mechanism. When the device is used, the box can be fixed under the drone for aerial spraying, so that the effective spraying position of the agent is more extensive. However, due to the limited load-bearing capacity of the drone, the amount of bacteria carried by the device is also limited. In addition, some agents need to be stirred and matched, which cannot be achieved by the device. A soil remediation agent spraying device is disclosed in the Chinese utility model patent with the authorization announcement number CN213102748U, which includes a base, a box and a water tank, wherein the bottom surface of the base is fixedly connected with a universal wheel to realize movement. However, in actual soil remediation, the field soil area that needs to be repaired is often large. If there is no other power equipment to cooperate, the efficiency of spraying is low if it is driven by the above-mentioned base movement. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 6 As shown, the utility model comprises a wheeled tractor, a box 1 and a spraying assembly 2, wherein the box 1 is arranged on a frame 4 of the wheeled tractor, and a storage stirring chamber 101 and an equipment chamber 102 are arranged inside the box 1, a stirring shaft 103 is arranged inside the storage stirring chamber 101, a pressure air pump 104 is arranged inside the equipment chamber 102, and an input end of the pressure air pump 104 is connected to the storage stirring chamber 101 through an input pipe 1042, as shown in FIG. Figures 2-3As shown, the spray assembly 2 includes a shell 207, a lifting and lowering adjustment device, an adjustment driving gear 202 and an adjustment driven gear 203, wherein the shell 207 cooperates with a slide groove arranged on the outside of the equipment cavity 102 through a slider 205 to achieve a sliding connection between the shell 207 and the outer wall of the equipment cavity 102, a nozzle 206 is arranged inside the upper end of the shell 207, an opening is arranged at the lower end of the shell 207, an output hose 1041 is arranged at the output end of the pressure air pump 104, and the output hose 1041 is inserted into the lower end opening of the shell 207. The shell 207 is provided with a plurality of nozzles 208 on the upper shell wall, and the rear ends of the nozzles 208 are connected to the nozzle 206. The lower part of the shell 207 is provided with a threaded section, and a nut is mounted on the threaded section, and the nut is fixed in the adjusting driven gear 203. The lifting and adjusting device and the adjusting driving gear 202 are both arranged on the equipment cavity 102, and the adjusting driving gear 202 is meshed with the adjusting driven gear 203 and driven to rotate through the lifting and adjusting device. When the utility model is working, the microbial agent is input into the storage stirring chamber 101 of the box body 1, and the stirring shaft 103 starts to rotate and stir as needed. When the wheeled tractor moves to the field, the pressure air pump 104 starts to input the microbial agent into each nozzle 208 of the spraying assembly 2 for spraying. Taking into account the different spraying objects and actual uses, the shell 207 of the spraying assembly 2 can be adjusted in height according to the actual height of the crop and the specific use needs. During adjustment, the lifting and lowering adjustment device drives the nut on the threaded section of the shell 207 to rotate by adjusting the driving gear 202 and the driven gear 203 to transfer torque. Since the nut cooperates with the threaded section at the bottom of the shell 207, the rotation of the nut drives the shell 207 to rise and fall to achieve the purpose of adjusting the height of the nozzle 208. The output hose 1041 needs to have a sufficient length to meet the height adjustment needs of the shell 207. In this embodiment, the slider 205 on the housing 207 can be a T-shaped slider that cooperates with the T-shaped slot provided on the outside of the device cavity 102 to prevent the housing 207 from detaching, and the nut and the threaded section are self-locking, which can ensure that the housing 207 stops at a suitable height, which is a well-known technology in the art. Figure 1 As shown, the storage and stirring chamber 101 of the box body 1 is provided with a plurality of feed ports 1011 for inputting corresponding bacterial agent liquids, and the feed ports 1011 are provided with plugs. When the bacterial agent is input, the feed ports 1011 are blocked by the plugs, which is a well-known technology in the art.

[0024] like Figure 2 As shown, the lifting and lowering adjustment device can use an adjustment motor 201 to achieve automatic adjustment according to actual needs. At this time, the adjustment driving gear 202 is installed on the output shaft of the adjustment motor 201, and the adjustment motor 201 is fixed in the equipment cavity 102. Figure 3As shown, the lifting and lowering adjustment device can also be manually adjusted by a hand wheel 209, in which case the adjusting active gear 202 is mounted on the axle of the hand wheel 209, and the upper end of the axle of the hand wheel 209 is rotatably mounted on the top wall of the equipment cavity 102. In addition, the adjusting motor 201, the pressure air pump 104 and other devices are all commercially available products, and their supporting systems are all centrally arranged in the equipment cavity 102.

[0025] like Figure 2 As shown, a shield 204 is provided on the outer wall of the equipment cavity 102, and the adjusting driven gear 203 is arranged in the shield 204 to prevent the sprayed liquid from falling on the adjusting driven gear 203, and a gear opening for the adjusting driven gear 203 to pass through is provided on the cavity wall of the equipment cavity 102 to achieve the cooperation between the adjusting driven gear 203 and the adjusting driving gear 202, and the shield 204 can also prevent impurities from entering the equipment cavity 102 through the gear opening.

[0026] The stirring shaft 103 of the utility model can adopt different stirring drive forms according to needs. One of the ways is to directly set a driving motor or a power source such as a motor on the frame 4 of the wheeled tractor and directly connect it to the rotating shaft 1031 of the stirring shaft 103 to achieve driving, but this method consumes relatively much energy.

[0027] like Figure 1 and Figures 4-5 As shown, in one embodiment of the present invention, the stirring shaft 103 is driven to rotate by the rear wheel shaft 501 of the tractor rear wheel 5 to achieve stirring, and the rear wheel shaft 501 transmits torque through the stirring transmission assembly 3, such as Figures 4-5 As shown, in this embodiment, the stirring transmission assembly 3 includes a driving sprocket 301, a transmission chain 302, a driven sprocket 304, a driving shaft 303, a driving bevel gear 306 and a driven bevel gear 307, wherein Figure 5 As shown, the driving sprocket 301 is idlingly arranged on the rear wheel shaft 501, and a linkage latch 308 is arranged on the driving sprocket 301, and a socket that cooperates with the linkage latch 308 is arranged on the wheel hub of the tractor rear wheel 5. When stirring is not required, the linkage latch 308 is Figure 5As shown, since the driving sprocket 301 is idling on the rear wheel shaft 501, the rotation of the rear wheel shaft 501 will not drive the driving sprocket 301 to rotate. When stirring is required, the linkage latch 308 is inserted into the socket on the hub of the tractor rear wheel 5. At this time, the rotation of the tractor rear wheel 5 drives the driving sprocket 301 to rotate. The driving shaft 303 is arranged on the frame 4 of the wheeled tractor, and the driven sprocket 304 is fixed to one end of the driving shaft 303, and the driving sprocket 301 is connected to the driven sprocket 304 through the transmission chain 302. The rotation of the driving sprocket 301 drives the driven sprocket 304 to rotate, and then drives the driving shaft 303 to rotate. The other end of the driving shaft 303 is provided with a driving bevel gear 306. The lower end of the rotating shaft 1031 of the stirring shaft 103 is rotatably installed on the frame 4, and a driven bevel gear 307 is provided on the rotating shaft 1031. The driving bevel gear 306 is meshed with the driven bevel gear 307. The driving shaft 303 transmits torque through the driving bevel gear 306 and the driven bevel gear 307 to drive the stirring shaft 103 to rotate to achieve stirring. This embodiment only relies on the walking and rotation of the tractor rear wheel 5 to drive the stirring shaft 103, and does not require an additional power source. When the utility model is used, the place where the microbial agent is injected into the box body 1 is often a distance away from the field area to be sprayed. In this way, when the wheeled tractor drives to the field to be sprayed, the stirring shaft 103 can start stirring the microbial agent. When the wheeled tractor reaches the field to be sprayed, the microbial agent has been fully stirred and can be sprayed directly, thereby saving time and improving the efficiency of the spraying operation.

[0028] like Figure 5 As shown, a support seat 305 is provided on the frame 4 , and the driving shaft 303 is rotatably mounted on the support seat 305 .

[0029] like Figure 6 As shown, in another embodiment of the utility model, the stirring shaft 103 can also be driven for stirring through the gearbox of the wheeled tractor. The driving structure and principle of this embodiment are the same as those of the CN209365899U patent. The engine of the wheeled tractor outputs power and drives the tractor rear wheel 5 to rotate through the gearbox and the drive shaft. At the same time, the power of the gearbox is transmitted to the gear oil pump and drives the gear oil pump to work. The gear oil pump works to pump out the hydraulic oil in the hydraulic oil tank and drives the hydraulic motor 6 to rotate, thereby transmitting torque through the reducer 7 and the reduction commutator 8 to drive the stirring shaft 103 to rotate.

[0030] The working principle of the utility model is:

[0031] When the utility model is working, the bacterial agent is input into the storage stirring chamber 101 of the box body 1, and the stirring shaft 103 starts to rotate and stir as needed. When the wheeled tractor moves to the field, the pressure air pump 104 starts to input the bacterial agent into each nozzle 208 of the spraying component 2 for spraying. Taking into account the different spraying objects and uses, the shell 207 of the spraying component 2 can be adjusted in height according to the actual height of the crop and the specific use needs. During adjustment, the lifting and adjusting device transmits torque through the adjusting driving gear 202 and the adjusting driven gear 203 to drive the nut on the threaded section of the shell 207 to rotate, thereby driving the shell 207 to lift and adjust the height of the nozzle 208.
