DETAILED DESCRIPTION

[0030] See also Figures 1 to 8 A tillage, weeding, and soil-raising sprayer includes a tractor 1. A tiller is towed on one side of the tractor 1 by a traction frame, wherein the traction plate is combined with a rocker arm to improve the straight-line travel and steering performance of the tiller. A hydraulic structure is provided on the traction frame to convert the mechanical energy of the tractor 1 engine into hydraulic energy to drive the hydraulic motor or oil cylinder to operate. The oil cylinder in this setting controls the lifting of agricultural implements through hydraulic pressure to adjust the tillage depth. The lifting rod connects the oil cylinder and the lower pull rod to transmit the lifting power. The tractor 1 pulling the tiller to move and drive the agricultural implement to lift is an existing technology and will not be described in detail. A spraying structure 2 is provided on the frame of the tractor 1. The spraying structure 2 enables the tractor 1 to spray while driving. A weeding structure 3 is provided under the tiller. The weeding structure 3 is capable of removing weeds inside the ridges and furrows. A linkage structure 7 is provided between the weeding structure 3 and the spraying structure 2. The linkage structure 7 enables the weeding structure 3 and the spraying structure 2 to work synchronously, so that the spraying structure 2 can work normally without an additional power source.

[0031] like Figure 1 and Figure 8 As shown, the spraying structure 2 includes a medicine box 201, and a flow limiting plate 208 is installed inside the medicine box 201. The setting of the flow limiting plate 208 can suppress the excessive shaking of the medicine inside the medicine box 201 when the tiller is transporting the medicine box 201, and reduce the impact force caused by the shaking of the water flow. A guide plate 207 is installed on the bottom side of the inner wall of the medicine box 201. Figure 8As shown, the left is high and the right is low, which can make the water in the medicine box 201 flow toward the output port, reducing the amount of medicine remaining in the medicine box 201. The medicine box 201 is installed on the tiller. A water pipe 202 is installed on the medicine box 201, and a plurality of nozzles 203 are installed on the water pipe 202. A plurality of water spray pipes 204 are bolted to the nozzles 203. The nozzles 203 can be connected to the water spray pipes 204, or they can be indirectly set. The specific situation is determined according to the spraying range. When there is no nozzle 203, the nozzle 203 can be connected to the water spray pipe 204. It is connected to a water spray pipe 204, and the valve on the pipe mouth 203 can be closed to prevent the outflow of medicine; a conical cover 205 is installed on the water spray pipe 204. When the tractor 1 is driving, the medicine in the medicine box 201 will be sprayed out through the water spray pipe 204 to spray the field and kill the weeds inside the field. The conical cover 205 sets a limit to the spraying range of the water spray pipe 204, preventing the medicine from being sprayed onto the growing crops, and protecting the crops inside the field.

[0032] like Figure 3 and Figure 5 As shown, the weeding structure 3 includes a universal transmission shaft 301, which is connected to the gearbox of the tractor 1, so that the gearbox drives the universal transmission shaft 301 to rotate. Since this is a prior art, it will not be described here. One end of the universal transmission shaft 301 is meshed with two sets of bevel gears 303, and both sets of bevel gears 303 are fixedly connected to a transmission rod 302. The transmission rod 302 is movably connected to the bottom side of the tiller frame through a connecting frame. The transmission rod 302 is movably connected to the connecting frame. A roller 304 is movably connected to the transmission rod 302. A rotary hoe 305 is provided below the connecting shaft 306. A transmission belt 307 is wound between the rotary hoe 305 and the roller 304. One end of the rotary hoe 305 is movably connected to the rotating hoe 305. There is a connecting shaft 306. When the universal joint shaft 301 rotates, it will drive the two transmission rods 302 to rotate. The cross-section of the transmission rod 302 is set to be rectangular, which is convenient for the subsequent fixation of the roller 304 after adjusting the position. When the transmission rod 302 rotates, it will drive the roller 304 to rotate. When the roller 304 rotates, it will rotate through the transmission belt 307. The transmission belt 307 will drive the rotary hoe 305 to rotate, turning over the soil and hoeing the field, removing the weeds inside the ridge, and thus playing a role in removing weeds.

[0033] like Figure 3 and 4As shown, a movable frame 5 is fixedly connected to the bottom side of the tiller, a movable shaft 501 is fixedly connected inside the movable frame 5, a connecting shaft 306 is slidingly connected to the movable shaft 501, an adjusting frame 601 is fixedly connected to one side of the movable frame 5, two sets of protective covers 6 are installed on the adjusting frame 601, and a fixed plow 8 is installed between the two sets of protective covers 6. When the above-mentioned rotary hoe 305 needs to adjust its position (the position adjustment of the rotary hoe 305 is determined according to the width of the ridge), the roller 304 can be translated on the transmission rod 302, and then the rotary hoe 305 can be moved on the movable shaft 501 through the connecting shaft 306, so that the position between the rotary hoes 305 can be changed to facilitate adaptation to ridges of different widths.

[0034] The above-mentioned protective cover 6 is located above the ridge surface when in use, and plays a protective role for the crops planted on the ridge surface. When working, the protective cover 6 will cover the top of the crops to prevent the medicine sprayed by the sprinkler pipe 204 from being sprayed onto the crops.

[0035] like Figure 4 and Figure 7 As shown, a limiting structure 4 is provided on both sides of the roller 304, and the limiting structure 4 includes a mounting plate 403, which is slidably connected to the transmission rod 302, and a symmetrical clamping block 401 is slidably connected to one side of the mounting plate 403, and the symmetrical clamping blocks 401 are clamped on the transmission rod 302. A threaded rod 402 is connected between the clamping blocks 401, and a rotating plate 404 is rotatably connected to the side of the mounting plate 403 adjacent to the roller 304. When the roller 304 translates on the transmission rod 302, the threaded rod 402 can be rotated. When the threaded rod 402 rotates, the clamping block 401 on the mounting plate 403 is rotated. They are close to each other, thereby clamping and fixing the transmission rod 302, fixing the positions of the rotating disk 404 and the mounting disk 403 on the transmission rod 302, thereby fixing the position of the roller 304, and preventing the roller 304 from self-moving during the rotation process. The connection between the connecting shaft 306 and the movable shaft 501 is rotatably connected with a limiting rod, and the limiting rod is threadedly connected to the connecting shaft 306. When the limiting rod rotates, it will press against the movable shaft 501, thereby fixing the position of the connecting shaft 306 on the movable shaft 501, so that the connecting shaft 306 and the rotary hoe 305 will not self-move.

[0036] like Figure 2 、 Figure 5 and Figure 6As shown, the linkage structure 7 includes a driving disk 701, which is fixedly connected to the transmission rod 302, and a connecting rod 702 is hinged on the driving disk 701. A fixed frame 703 is fixedly connected to the tiller, and a sliding rod 704 is slidably connected to the interior of the fixed frame 703. The sliding rod 704 is hinged to the connecting rod 702. The output port of the medicine box 201 is fixed and connected with a water diversion pipe 707. One end of the water diversion pipe 707 is fixed and connected with a fixed pipe 705. The interior of the fixed pipe 705 is slidably connected with a piston rod 706. The piston rod 706 is fixedly connected to the sliding rod 704. One side of the fixed pipe 705 is connected with the water diversion pipe 202. A one-way valve 708 is installed inside the water diversion pipe 202 and the water diversion pipe 707. Valves are installed on the pipe mouth 203. The water diversion pipe 202 is connected to both sides of the medicine box 201 respectively. A stop valve 206 is installed. When the transmission rod 302 rotates, it will drive the driving disk 701 to rotate. When the driving disk 701 rotates, it will drive the hinged connecting rod 702 to make a circular motion, and then drive the sliding rod 704 connected thereto to make a reciprocating up and down motion inside the fixed frame 703. The sliding rod 704 drives the piston rod 706 to make a reciprocating up and down motion inside the fixed tube 705. When the piston rod 706 moves up inside the fixed tube 705, suction is generated, causing the medicine in the medicine box 201 to flow into the interior of the fixed tube 705 through the water diversion pipe 707. When the piston rod 706 moves down, the pressure generated causes the water to be discharged only through the water diversion pipe 202 (the setting of the one-way valve 708 prevents the medicine from flowing back into the medicine box 201 through the water diversion pipe 707). The water discharged through the water diversion pipe 202 will be sprayed out through the water spray pipe 204, completing the spraying of the medicine.

[0037] Specifically, when some furrows do not need to be sprayed with medicine and only the rotary hoe 305 is needed to hoe the ground, the valve on the pipe mouth 203 can be closed and the stop valve 206 can be opened at the same time. In this way, the medicine drawn out from the inside of the water pipe 707 will flow back to the inside of the medicine box 201 through the water pipe 202, and cannot be sprayed out from the pipe mouth 203 and the water pipe 204, thereby achieving the purpose of only needing to rotate the hoe 305 to hoe the ground without spraying medicine.

[0038] Working principle: When the transmission rod 302 rotates, it drives the roller 304 to rotate. When the roller 304 rotates, it rotates through the transmission belt 307. The transmission belt 307 drives the rotary hoe 305 to rotate, turning over the soil in the field and removing the weeds inside the ridge, thereby playing a role in removing weeds. When the transmission rod 302 rotates, it drives the driving disc 701 to rotate. When the driving disc 701 rotates, it drives the hinged connecting rod 702 to make a circular motion, thereby driving the sliding rod 704 connected to it to move on the fixed frame. The interior of 703 makes a reciprocating up and down motion, and the sliding rod 704 drives the piston rod 706 to make a reciprocating up and down motion inside the fixed tube 705. When the piston rod 706 moves up inside the fixed tube 705, suction is generated, causing the medicine in the medicine box 201 to flow into the interior of the fixed tube 705 through the water guide pipe 707. When the piston rod 706 moves down, the pressure generated causes the water to be discharged only through the water guide pipe 202. The water discharged through the water guide pipe 202 will be sprayed out through the water spray pipe 204, completing the spraying of the medicine.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
