Technical Field
[0001] This utility model belongs to the field of agricultural equipment technology, specifically a spraying device for wheat planting in agricultural production. Background Technology
[0002] In agricultural production, spraying equipment used in wheat cultivation is a tool for spraying pesticides, foliar fertilizers, and other substances onto wheat. It mainly includes manual sprayers, which rely on manual operation to generate pressure to spray; backpack motorized sprayers and dusters, which are powered by small engines and are convenient for moving around in the field; and large self-propelled boom sprayers, which have multiple nozzles and a large tank, and can spray wheat over a large area efficiently through mechanical self-propelled operation. These devices can effectively prevent and control pests and diseases and promote wheat growth.
[0003] A search revealed that CN213074196U discloses an insecticide spraying device for tea cultivation, including a cart base plate. A fixing ring is fixedly connected to one side of the top of the cart base plate, and a limiting angle iron is fixedly connected to the other side of the top of the cart base plate. A pesticide storage tank is fixedly connected to the cart base plate via the fixing ring, and a battery is fixedly connected to the cart base plate via the limiting angle iron. This invention, through the inclusion of casters and a cart handle, facilitates the movement of the device. Therefore, when using this spraying device, it avoids injury to the user due to excessive weight, and effectively reduces the labor required for spraying.
[0004] During the spraying process, due to the large area of farmland, the nozzle needs to spray a wide area. However, the spray pipe in the above-mentioned device is fixed on the storage tank and cannot rotate while moving. It can only spray the front end in the direction of movement, which is relatively limited. It may be necessary to repeat the operation many times to complete the large-area spraying operation. It is also impossible to adjust the spraying range according to the actual size of the farmland. Therefore, in order to solve the above problems, a spraying device for wheat planting in agricultural production is proposed. Utility Model Content
[0005] To address the problems mentioned in the background section, this utility model provides a spraying device for wheat cultivation in agricultural production, which solves the problem that the existing technology cannot adjust the spraying range.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 4 As shown, this utility model provides a spraying device for wheat planting in agricultural production, including a base 1. A medicine box 4 is fixedly connected to the top outer wall of the base 1. A nozzle 5 is provided on the outer wall of the medicine box 4. A rotating mechanism 2 is provided on the top outer wall of the base 1 through a lifting mechanism 3. The rotating mechanism 2 includes a motor 208. A turntable 201 is fixedly connected to the output shaft of the motor 208. A groove 202 is provided on the inner wall of the turntable 201. A moving block 203 is slidably connected to the inner wall of the turntable 201. An insert block 205 is elastically connected to the inner wall of the moving block 203 through a connecting spring 204. A slider 206 is slidably connected to the outer wall of the medicine box 4. A rotating rod 207 is hinged to the outer wall of the slider 206.
[0023] The above-mentioned scheme employs the following: Multiple sets of casters are installed below the base 1; a handle is installed on the outer wall of the medicine tank 4, allowing the operator to push the handle and use the casters to move the entire device in the wheat field for spraying; the medicine tank 4 is connected to the nozzle 5 via a connecting pipe, which is connected to the medicine tank 4 via a negative pressure pump. The negative pressure pump can draw out the pesticide solution from the medicine tank 4 and spray it from the nozzle 5 to spray the wheat, which is existing technology; the rotating mechanism 2 can drive the nozzle 5 to rotate horizontally at a certain angle while spraying, and the rotation angle of the nozzle 5 can be adjusted to meet the needs of different spraying ranges; the motor 208 serves as the power source, and its output shaft can drive the turntable 201 to rotate. The moving block 203 slides on the inner wall of the turntable 201, and the connecting spring 204 inside it applies downward pressure to the insert block 205. The elasticity of the spring allows the insert 205 to be tightly engaged with a set of grooves 202, thus ensuring that the moving block 203 moves in a circular motion as the turntable 201 rotates. When the moving block 203 moves in a circular motion driven by the turntable 201, the moving block 203 will contact the inner wall of the rotating rod 207 and generate a pushing force on the rotating rod 207, causing the rotating rod 207 to flip laterally along its connection with the slider 206. Through the continuous rotation of the turntable 201, the moving block 203 moves in a circular motion and can drive the rotating rod 207 to flip laterally back and forth, and drive the nozzle 5 to move synchronously, thereby realizing the reciprocating swing of the nozzle 5. Since the connecting pipe between the nozzle 5 and the medicine tank 4 is a flexible and retractable hose, it will not affect the swing of the nozzle 5, thereby expanding the coverage area of the spray and improving the uniformity and efficiency of the spray.
[0024] like Figures 2 to 3 As shown, one end of the connecting spring 204 is fixedly connected to the outer wall of the insert block 205, and the other end of the connecting spring 204 is fixedly connected to the inner wall of the moving block 203; the insert block 205 is slidably connected to the inner wall of the moving block 203, and the insert block 205 is engaged with the groove 202; the rotating rod 207 is fixedly connected to the outer wall of the nozzle 5, and the moving block 203 is in contact with the inner wall of the rotating rod 207.
[0025] Using the above scheme: the insert block 205 can move up and down within the inner wall of the movable block 203. When the insert block 205 is pulled upwards, the connecting spring 204 contracts under force, and the insert block 205 disengages from the groove 202, thus releasing the limiting position of the movable block 203. At this time, the movable block 203 is moved along the groove of the turntable 201 so that the position of the insert block 205 corresponds to that of another set of grooves 202. When the insert block 205 is released, it pops downwards under the elastic force of the connecting spring 204. It engages with the groove 202 and fixes the position of the moving block 203. When the moving block 203 moves toward the center of the turntable 201, it reduces the radius of rotation of the turntable 201, thereby reducing the angle at which the moving block 203 drives the rotating rod 207 to reciprocate. When it moves toward the circumference of the turntable 201, it increases the moving radius and increases the angle at which it drives the rotating rod 207 to reciprocate. This allows for convenient and quick adjustment of the rotation range of the rotating rod 207 to meet different spraying needs.
[0026] like Figure 4 As shown, the lifting mechanism 3 includes a fixed block 306, with a slot 307 on the inner wall of the fixed block 306. A bracket 301 is slidably connected to the inner wall of the fixed block 306. A movable plate 303 is elastically connected to the inner wall of the bracket 301 via a return spring 302. A locking block 305 is hinged to the outer wall of the movable plate 303 via a hinge rod 304. The fixed block 306 is fixedly connected to the top outer wall of the base 1. The motor 208 is fixedly connected to the bottom outer wall of the bracket 301. The turntable 201 is rotatably connected to the top outer wall of the bracket 301. The two ends of the hinge rod 304 are respectively hinged to the locking block 305 and the outer wall of the movable plate 303. One end of the return spring 302 is fixedly connected to the outer wall of the movable plate 303, and the other end of the return spring 302 is fixedly connected to the inner wall of the bracket 301. The locking block 305 is slidably connected to the inner wall of the bracket 301 and engages with the slot 307.
[0027] The above scheme is adopted: the bracket 301 provides a supporting foundation for the entire rotating mechanism 2, and it can slide on the inner wall of the fixed block 306 to adjust the overall height of the rotating mechanism 2, thereby adjusting the height of the nozzle 5 and further changing the spraying range; the outer wall of the moving plate 303 is provided with a lever, which passes through the outer wall of the bracket 301. Under the condition of no external force, the return spring 302 keeps the moving plate 303 fixed in the bracket 301, and the locking block 305 engages with the corresponding locking groove 307 to fix the position of the bracket 301 in the fixed block 306; when it is necessary to adjust the height of the lifting mechanism, the lever on the outer wall of the moving plate 303 can be pushed upward to compress the return spring 302. The moving plate 303 drives the hinge rod 304 to flip in the middle, and through the hinge rod The transmission of 304 causes the locking block 305 to move. Since the locking block 305 can only move laterally within the inner wall of the bracket 301, it can drive both sets of locking blocks 305 to move towards the center simultaneously and disengage from the locking groove 307 on the inner wall of the fixed block 306, releasing the limit of the bracket 301, which can then be moved up and down for adjustment. When the bracket 301 moves up and down, the rotating mechanism 2 moves synchronously, the slider 206 moves on the outer wall of the medicine tank 4, and the nozzle 5 moves with the rotating rod 207, thus adjusting the height of the nozzle 5. In this way, the height of the nozzle 5 can be flexibly adjusted according to the height of the wheat at different growth stages, ensuring that the pesticide can be accurately sprayed on the appropriate position of the wheat plant, avoiding pesticide waste or poor spraying effect caused by unsuitable nozzle height.
[0028] Working principle and usage process of this utility model:
[0029] The operator can push the handle at the rear of the medicine box 4 to move it in the wheat field and adjust the required nozzle 5 according to the growth stage of the wheat. By pushing the lever on the outer wall of the moving plate 303 upward, the return spring 302 is compressed. The moving plate 303 drives the hinge rod 304 to flip in the middle, so that the locking block 305 moves in the middle and disengages from the locking groove 307 on the inner wall of the fixed block 306, releasing the limit of the bracket 301. The bracket 301 can then be moved up or down. At this time, the entire rotating mechanism 2 moves synchronously, and the nozzle 5 will move up and down with the rotating rod 207, thereby realizing the adjustment of the height of the nozzle 5. After adjustment, the lever is released. Under the action of the return spring 302, the moving plate 303 moves downward. The hinge rod 304 flips and drives the two sets of locking blocks 305 to move laterally to both sides. The locking blocks 305 re-engage with the other set of locking grooves 307, thus fixing the position of the bracket 301.
[0030] Next, the motor 208 can be started. The output shaft of the motor 208 drives the turntable 201 to rotate. The moving block 203 moves in a circle with the turntable 201 and contacts the inner wall of the rotating rod 207, generating a thrust on the rotating rod 207. This causes the rotating rod 207 to rotate laterally along its connection with the slider 206. Through the continuous rotation of the turntable 201, the moving block 203 drives the rotating rod 207 to rotate laterally back and forth, thereby driving the nozzle 5 to move synchronously and realize the reciprocating swing of the nozzle 5. At the same time, the negative pressure pump draws out the liquid medicine from the medicine tank 4 and sprays it out from the nozzle 5 to spray the wheat evenly.
[0031] The rotation angle of the nozzle 5 can be adjusted according to the required spraying range. To increase the rotation angle, pull the insert block 205 upwards, causing the connecting spring 204 to contract under force. This disengages the insert block 205 from the groove 202, releasing the limiting position of the moving block 203. Move the moving block 203 circumferentially along the groove of the turntable 201, aligning the insert block 205 with the position of another set of grooves 202. Then release the insert block 205. Under the elastic force of the connecting spring 204, the insert block 205 pops downwards and aligns with the groove. 202 engages to fix the position of the moving block 203. At this time, the radius of the moving block 203 increases with the rotation of the turntable 201, which in turn increases the angle of the reciprocating rotation of the rotating rod 207, thereby expanding the swing range of the nozzle 5. When it is necessary to reduce the rotation angle, the moving block 203 is moved towards the center of the turntable 201, which reduces the rotation radius of the moving block 203 and thus reduces the angle of the reciprocating rotation of the rotating rod 207. This allows the reciprocating spray range of the nozzle 5 to be adjusted to meet the spraying operation requirements of different ranges.
