[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-7 The utility model of saline-alkali land treatment device comprises a frame 1, a rotary tiller 3 is arranged at the front end of the frame 1, a medicine box 2 is arranged on the top of the frame 1, a medicine application mechanism 4 is arranged below the medicine box 2, and the medicine application mechanism 4 is located behind the rotary tiller 3;

[0029] The pesticide application mechanism 4 includes a plurality of dividing plates 11 closely arranged along the axial direction of the rotary tiller 3. The bottom of the dividing plate 11 is higher than the bottom of the rotary tiller 3. The dividing plate 11 is in the shape of a plow. A pesticide nozzle 13 connected to the pesticide box 2 is arranged on the inner side of the dividing plate 11. The width of the spray width 15 sprayed by the pesticide nozzle 13 is the same as the width of the dividing plate 11.

[0030] The rotary tiller 3 includes a rotary shell, a connecting frame, a tilling blade, a blade shaft, a main transmission box, and a sub-transmission box. The main transmission box is installed on the top of the shell, the sub-transmission box is installed on the side of the shell, the connecting frame is installed on the top of the shell, the frame 1 and the top plate of the shell are formed as one piece, and a transmission shaft is provided on the transmission box. When in use, it is connected to a traction device such as a tractor through the connecting frame, and the transmission shaft is connected to the output shaft of the traction device through a cross coupling, and the rotary tiller 3 is driven to operate through the traction device.

[0031] The rotary tiller 3 can be a horizontal axis type or a vertical axis type rotary tiller, and can be selected according to the required rotary tillage depth.

[0032] The soil dividing plate 11 is located below the soil surface during the moving process. Its function is not to plow the land, but to separate the soft soil tilled by the rotary tiller 3, so that the pesticide spray head 13 has a certain spraying space when spraying the pesticide, avoiding the spray width 15 being blocked by the soil and narrowed.

[0033] At the same time, the soil dividing plate 11 does not leak out of the ground. First, the soil can automatically close after the soil dividing plate 11 and the agent nozzle 13 pass through. Second, the sprayed agent never contacts the ground surface, thereby reducing the evaporation of the agent and making all the agents act on the soil below the ground surface, further ensuring the desired effect.

[0034] The width of the spray width 15 of the soil dividing plates 11 arranged closely in the transverse direction is the same as that of the soil dividing plates 11, so that two adjacent spray widths 15 can be almost connected together, avoiding the need to increase the amount of medicine in large areas due to the need to wet the soil in the unsprayed area, thereby reducing the waste of medicine.

[0035] The soil dividing plate 11 is assembled from two congruent triangular plates, one pair of equilateral sides of the two triangular plates are connected together, the front ends of the two triangular plates are low and the rear ends are high, the middle is high and the two sides are low, and the agent spray head 13 is located in the middle of the inner sides of the two triangular plates.

[0036] The triangular plate can be a flat triangular structure or a curved triangular structure, forming a shape similar to a plow. During the movement, the soil dividing plate 11 pushes the soil from the middle to both sides, and then the pesticide nozzle 13 stands in the soil space separated by the soil dividing plate 11 to spray the pesticide, thereby increasing the spraying range and improving the spraying efficiency.

[0037] An extension plate 14 is provided at the rear end of the triangular plate, and the medicine spray head 13 is located at the front lower side of the extension plate 14 .

[0038] This prevents the separated soil from being quickly backfilled from the rear of the soil dividing plate 11 to the inner side of the soil dividing plate 11 , thereby further increasing the spraying range of the agent spray head 13 .

[0039] The pesticide application mechanism 4 includes a pesticide application frame 6, on which a lifting rod 7 is arranged in the vertical direction, and a pesticide application hard pipe 12 is arranged on the inner side of the lifting rod 7. The top of the pesticide application hard pipe 12 is connected to the medicine box 2 through a pesticide application hose 8, and the bottom of the pesticide application hard pipe 12 is provided with a soil dividing plate 11 and a medicine nozzle 13.

[0040] The lifting rod 7 penetrates the frame 1 upward and is movably connected to the frame 1. By adjusting the height of the lifting rod 7 and coordinating the tillage depth of the rotary tiller 3, the soil dividing plate 11 and the agent spray head 13 are driven to rise or fall synchronously, thereby adjusting the spraying depth of the agent.

[0041] Of course, the drug application mechanism 4 also includes a liquid pump for pumping medicine, the inlet of the liquid pump is connected to the medicine box 2, the outlet of the liquid pump is connected to the inlet end of the drug application hose 8, and the liquid pump can be driven by the power supply of the traction equipment.

[0042] A lifting seat 9 is provided on the spraying frame 6, and a through slot corresponding to the lifting rod 7 is opened on the lifting seat 9. A tightening bolt 10 is provided on the side of the lifting rod 7. The end of the tightening bolt 10 penetrates the spraying frame 6 and then presses on the outer wall of the lifting rod 7.

[0043] When the jacking bolt 10 is loosened, the jacking bolt 10 is away from the lifting rod 7, so that the lifting rod 7 is loosened, and the position of the lifting rod 7 is adjusted up and down to adjust the height of the medicine spray head 13 and the soil dividing plate 11.

[0044] The lifting rod 7 is a triangular prism structure, and the side edges of the lifting rod 7 face forward.

[0045] The lower part of the lifting rod 7 that is convenient to extend into the soil below the surface can also reduce resistance when easily separating the soil.

[0046] The rear end of the pesticide application mechanism 4 is connected to a screed plate 5 .

[0047] The screed plate 5 and the pesticide application frame 6 are softly connected by a chain. The screed plate 5 mainly uses its own weight to level the slightly raised soil separated by the soil dividing plate 11 during the movement, thereby ensuring the covering effect of the soil after the pesticide application.

[0048] Working principle: When in use, the device is connected to the traction equipment, and the device is pulled forward by the traction equipment. During the movement, the rotary tiller 3 breaks and loosens the saline-alkali soil in the front, and then the soil dividing plate 11 separates the soft soil from below the surface. The agent nozzle 13 sprays the agent in the middle of the separated soil, and the spray width 15 of the agent covers the separated soil space. After the soil dividing plate 11 passes, the separated soil is automatically backfilled to the original position to cover the agent, and the leveling plate 5 levels the raised soil.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
