[0002] Contaminated farmland refers to land where harmful substances in the soil exceed safe levels. This pollution can come from various sources, including industrial emissions, pesticide and fertilizer residues, and improper waste disposal. Contaminated farmland can have serious impacts on plant growth, environmental health, and human safety. To address the impacts of harmful soil substances on plant growth and crop health, foliar control sprayers are needed for pest and disease control.

[0003] The prior art has the following defects: some of the existing sprayers are equipped with multiple nozzles to increase the spraying range, but the positions of the multiple nozzles of some devices are in a specified state and cannot be changed, resulting in the nozzles of small-scale contaminated farmland still being used, which leads to waste of liquid medicine, while the contaminated farmland in a larger area cannot be adjusted according to the actual situation later. Secondly, the pipes of some sprayers are simply wrapped and stored, resulting in poor storage tidiness after the sprayers are used, and the pipes are easily in contact with the ground during dragging, which is easy to cause pipe wear. Therefore, a foliar barrier sprayer for safe use of contaminated farmland is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a foliar control agent sprayer for safe utilization of contaminated cultivated land, comprising a spray barrel 1, a handle 3 fixedly connected to the side wall of the spray barrel 1 through a connecting pipe 2, the handle 3 is used to control the spraying position of the nozzle 6, the handle 3 has a hard outer surface and a hollow middle, and can allow the liquid medicine to be input into the collection box 4, the left end of the handle 3 is fixedly connected to the collection box 4, the handle 3 and the collection box 4 are interconnected, and can allow the water pump in the spray barrel 1 to inject the liquid medicine into the collection box 4 Inside, let the centralized box 4 distribute the liquid medicine to the nozzle 6. The outer wall of the centralized box 4 is fixedly connected with a support frame 5. The outer wall of the support frame 5 is slidably connected with the nozzle 6. The nozzle 6 is an existing mist spray head. The mist spray can more accurately control the spraying amount of the leaf control agent and reduce the waste of the control agent. Since the mist spray can evenly distribute the control agent on the contaminated farmland, the top of the nozzle 6 is fixed with a connecting rod 7. The tail of the nozzle 6 is connected with a delivery pipe. The other end of the delivery pipe is connected to the bottom end of the centralized box 4. Figure 1 and Figure 2 As shown, the liquid medicine in the central box 4 can be transferred to the nozzle 6 through the delivery pipe. The outer wall of the central box 4 is slidably connected to the movable plate 8. The movable plate 8 is provided with an inclined groove, and the connecting rod 7 can be squeezed through the inclined groove to move the nozzle 6. The inner wall of the movable plate 8 is elastically connected to the rotating rod 10 through the torsion spring 9. The outer wall of the rotating rod 10 is provided with a limiting mechanism. The top of the central box 4 is fixedly connected to the support column 12.

[0032] Reference Figure 4-Figure 5 The side wall of the spray barrel 1 is fixedly connected with a winding disk 13. The middle gap of the winding disk 13 can allow the connecting pipe 2 to be wound to its inner surface. The inner wall of the winding disk 13 is slidably connected with a connecting sleeve 14. The connecting sleeve 14 is provided with two groups. The two groups of connecting sleeves 14 are elastically connected by a return spring 15. One end of the return spring 15 is fixedly connected to the inner wall of the left end connecting sleeve 14, and the other end of the return spring 15 is fixed to the inner wall of the right end connecting sleeve 14. When the connecting sleeves 14 are separated from each other, the return spring 15 will be compressed. When resetting, the elastic force of the return spring 15 is used to restore the connecting sleeve 14. The upper end of the sleeve 14 is fixedly connected to a blocking block 16, which is an inclined surface. When subjected to a greater force from the hand, the inclined surface of the blocking block 16 will be squeezed, allowing the blocking block 16 to slide along the inner wall of the winding disk 13 with the connecting sleeve 14. The blocking block 16 contacts the outer wall of the connecting pipe 2. The connecting pipe 2 is a hose with a certain hardness. The hose after winding has a partial rotational reset force. Since the reset spring 15 has a large elastic force, the blocking block 16 can prevent the hose from rotating and resetting after winding. The winding disk 13 contacts the outer wall of the connecting pipe 2, and the blocking block 16 penetrates and is slidably connected to the inner wall of the winding disk 13.

[0033] Reference Figure 1-Figure 3The inner wall of the movable plate 8 is fixedly connected to one end of the torsion spring 9. At this time, the torsion spring 9 is in the initial state. When the rotating rod 10 rotates, the torsion spring 9 is compressed. When resetting, the elastic force of the torsion spring 9 is used to reset the rotating rod 10. The other end of the torsion spring 9 is fixedly connected to the outer wall of the rotating rod 10. The rotating rod 10 is rotatably connected to the inner wall of the movable plate 8. The limiting mechanism includes a card plate 11, which is fixedly connected to the outer wall of the rotating rod 10. The card plate 11 is clamped with the outer wall of the support column 12. The outer wall of the support column 12 is provided with a notch corresponding to the card plate 11, which can allow the notch of the support column 12 to block the vertical movement of the card plate 11, and the connecting rod 7 is slidably connected to the inner wall of the movable plate 8.

[0034] Working principle: First, when the spraying position of the nozzle 6 can be adjusted according to the spraying range, you only need to turn the rotating rod 10 forward to separate the card plate 11 from the outer wall slot of the support column 12, and then move the rotating rod 10 upward to move the card plate 11 and the movable plate 8 upward, so that the inclined groove of the movable plate 8 squeezes the connecting rod 7 to make the connecting rod 7 move with the nozzle 6, so that the distance between the nozzles 6 becomes larger, and the overall spraying range is increased. When limiting is required, you only need to reverse the rotating rod 10 to bring the card plate 11 into the outer wall slot of the support column 12, and use the elastic force of the torsion spring 9 to keep the card plate 11 continuously in the outer wall slot of the support column 12, so that the position of the movable plate 8 will not change. When it needs to be adjusted again, just follow the above steps. It can be adjusted according to the area of ​​contaminated cultivated land to be sprayed.

[0035] When in use, just follow the above steps and use the force of your hand to pull the connecting pipe 2 outward and squeeze the blocking block 16. After the connecting pipe 2 is wound around the inner wall of the winding disk 13, the elastic force of the reset spring 15 resets the blocking block 16.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
