Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural planting technology, and in particular to a spraying device for tall plants. Background Technology
[0002] Pesticide spraying is necessary during crop growth. Conventionally, backpack sprayers are used for pesticide spraying. By shaking the rocker arm, the rubber cup opens and closes repeatedly in the pump and air chamber, thereby gradually increasing the pressure inside the air chamber (up to 0.6 MPa). The pesticide solution at the bottom of the tank passes through the water outlet pipe, then through the spray bar, and finally is sprayed out as a mist from the nozzle.
[0003] In existing technologies, the nozzle of backpack sprayers needs to be held manually and always in front of the person. The sprayed pesticides remain in the air in front of the person, and when the person walks over, some of the pesticides will get on their body and face, reducing the effectiveness of the pesticide spraying. At the same time, the spraying height is limited, and it is inconvenient to hold the nozzle and spray pesticides onto the leaves of tall plants such as sorghum and corn. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for the nozzle to always be positioned in front of the user, pesticide residues remaining in the air ahead, and the user getting some pesticide on their body and face when walking past, thus reducing the effectiveness of pesticide spraying. Therefore, this invention proposes a spraying device for tall plants.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A spraying device for tall plants includes a pesticide tank for holding pesticides, and two shoulder straps are fixed to the side of the pesticide tank, with cotton pads fixed inside each of the two shoulder straps.
[0007] The top of the medicine box is fixed with two fixed frames, and the same connecting slide rod slides inside the two fixed frames. Multiple atomizing nozzles are fixed on both sides of the connecting slide rod. The multiple atomizing nozzles are used to spray the pesticides contained in the medicine box.
[0008] A swing assembly, located inside the medicine tank, is used to drive multiple atomizing nozzles to perform lateral swinging pesticide spraying.
[0009] A feeding assembly, which is located inside the medicine tank and is used to deliver pesticides into the connecting slide bar;
[0010] The medicine box is equipped with a feeding pipe for feeding, and the surface of the feeding pipe is threaded with a sealing cap.
[0011] In one possible design, four limiting rings are fixed to the surface of the connecting slide rod, and two limiting gaps are formed between the four limiting rings. The two fixing brackets are respectively disposed in the two limiting gaps.
[0012] In one possible design, the oscillating assembly includes a first groove formed inside the medicine box and a semi-toothed ring sliding within the first groove. A rotating shaft rotates within the first groove. A semi-toothed gear that intermittently meshes with the semi-toothed ring is fixed to the surface of the rotating shaft. A connecting block is fixed to the side end of the semi-toothed ring. A connecting rod is fixed to the top of the connecting block. A connecting ring is fixed to the surface of the connecting slide rod. The connecting rod is fixed to the surface of the connecting ring. A drive motor is fixed to the top of the medicine box. The drive motor is fixedly connected to the rotating shaft via a coupling.
[0013] In one possible design, the feeding assembly includes a water pump fixed to the top of the medicine box, with an inlet pipe fixed to the water pump's inlet. The swing assembly includes a first groove (17) formed inside the medicine box and a semi-toothed ring sliding within the first groove. A rotating shaft rotates within the first groove, and a semi-toothed gear intermittently meshes with the semi-toothed ring on the surface of the rotating shaft. A connecting block is fixed to the side end of the semi-toothed ring, and a connecting rod is fixed to the top of the connecting block. A connecting ring is fixed to the surface of the connecting slide rod, and an electric push rod is fixedly mounted on the top of the connecting rod. The output shaft of the electric push rod is fixed to the surface of the connecting ring. A drive motor is fixed to the top of the medicine box, and the drive motor is fixedly connected to the rotating shaft via a coupling.
[0014] In one possible design, the fixing frame includes a lower fixing frame, a rectangular groove, a rectangular plate, and an upper fixing frame. The rectangular plate is fixedly installed at the bottom of the upper fixing frame, the rectangular groove is located at the top of the lower fixing frame, the rectangular plate is slidably connected in the rectangular groove, the lower fixing frame is fixed at the top of the medicine box, and the upper fixing frame is slidably connected to a connecting slide rod.
[0015] In one possible design, the feeding assembly includes a water pump fixed to the top of the medicine tank, an inlet pipe fixed to the inlet of the water pump, the inlet pipe moving downwards through the medicine tank, and a delivery pipe fixed to the outlet of the water pump, the delivery pipe being fixedly connected to a connecting slide rod.
[0016] In one possible design, a counterweight is fixed to the surface of the water inlet pipe, and the counterweight is located on the lower side of the water inlet pipe.
[0017] In one possible design, the bottom of the medicine box is fixed with an anti-slip base.
[0018] In this application, after unscrewing the sealing cap and filling the pesticide tank with pesticide, the person carries the pesticide tank on their back, starts the water pump and drive motor, the water pump draws water from the pesticide tank through the water inlet pipe, and then sends it to the connecting slide rod through the water delivery pipe, and sprays it onto the crops through multiple atomizing nozzles.
[0019] The drive motor is started to rotate the shaft, which in turn drives the half-tooth gear to rotate. The half-tooth gear drives the half-tooth ring to slide back and forth in a straight line in the first groove. The half-tooth ring drives the connecting block to slide synchronously. The connecting block drives the connecting slide rod to slide back and forth in the two fixed frames through the connecting rod and the connecting ring, so that the atomizing nozzles on both sides continue to swing and spray, ensuring the coverage of multiple atomizing nozzles. Beneficial effects
[0020] In this utility model, the spraying equipment for tall plants can achieve the effect of automatically spraying materials, replacing manual labor, through the feeding component.
[0021] In this utility model, the spraying device for tall plants can drive the atomizing nozzles on both sides to swing and feed through the swinging component, thus ensuring the uniformity of pesticide spraying.
[0022] In this invention, the connecting slide bar and the atomizing nozzle are located at the rear of the medicine tank, behind the person's back. When spraying, the person moves forward and the pesticide is sprayed from behind, so it will not fall on the person's face, making it more convenient.
[0023] In this invention, the feeding pipe, water inlet pipe, and water delivery pipe are reasonably designed to ensure smooth delivery of pesticides, and the counterweight design prevents the water inlet pipe from floating, thus ensuring the stability of the feeding. Attached Figure Description
