Technical Field

[0001] This utility model belongs to the field of pesticide spraying, and in particular relates to a pesticide spraying device for vegetable planting. Background Technology

[0002] Vegetable cultivation refers to the agricultural production process from sowing and seedling raising to harvesting through artificial cultivation techniques. It involves soil management, water and fertilizer regulation, and pest and disease control, aiming to produce edible vegetable crops on a large scale. In open-field planting environments, pests and diseases such as aphids, cabbage caterpillars, and downy mildew have extremely high incidence rates, causing damage to an average of 3 billion mu (approximately 200 million hectares) of land annually. Without the use of pesticides, this can lead to yield reductions of more than 30% or even total crop failure.

[0003] Existing pesticide spraying equipment for vegetable cultivation is mostly sprayers, commonly including manual or electric sprayers. When spraying pesticides on vegetables, whether in flat or complex farmland, workers need to carry the water tank containing pesticide solution on their backs to move the sprayer. However, this method of moving is too simplistic and cannot be switched according to the terrain. Carrying the water tank for a long time increases the physical burden on workers, quickly depletes their physical strength, and increases the intensity of their labor. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0024] This embodiment describes a pesticide spraying device for vegetable cultivation, such as... Figure 1 , Figure 2 and Figure 6 As shown, the device includes a horizontally arranged base plate 1, on which a sprayer body 4 is mounted. The sprayer body 4 is fixed to the top of the base plate 1, making the sprayer body 4 and the base plate 1 a single unit. In this embodiment, the sprayer body 4 is an electric sprayer, which consists of an electric pump, a water tank, a connecting pipe, a spray pipe, a nozzle, a power system, a control switch, and other components. The electric sprayer achieves efficient atomization through pressurization by the electric pump, and combines functionality, safety, and portability, making it suitable for agricultural plant protection, disinfection operations, and other similar applications.

[0025] A swing rod 8 is hinged to the base plate 1, such as Figure 1 and Figure 2 As shown, the end of the horizontal section of the swing rod 8 is hinged to the bottom of the base plate 1 via a pivot. A hinge seat is fixed to the bottom of the base plate 1, and the pivot is horizontally fixed on the hinge seat. A mounting hole for the pivot is provided on the horizontal end of the swing rod 8, so that the swing rod 8 can swing around the hinge point as the center. Of course, the horizontal end of the swing rod 8 can also be hinged to the bottom of the base plate 1 via a hinge.

[0026] A roller 9 is installed on the swing end of the swing rod 8, such as... Figure 2 and Figure 6 As shown, the roller 9 is mounted on the swing end of the swing rod 8 via a rotating shaft. When the roller 9 swings to a vertical position facing the ground, it supports the pesticide spraying device. When the worker pushes the pesticide spraying device, the roller 9 rolls along the ground, making it easier and more convenient for the worker to move the pesticide spraying device.

[0027] To elaborate further, such as Figure 2 , Figure 3 and Figure 7 As shown, in this embodiment, a preferred embodiment includes a fixed plate 11, and the swing rod 8 has an "L"-shaped structure, with the horizontal end of the swing rod 8 hinged to the bottom of the base plate 1; as shown Figure 8 As shown, after the swing rod 8 swings upward, the vertical section of the swing rod 8 is aligned parallel to the front side wall of the sprayer body 4, so that the roller 9 is located on the front side of the sprayer body 4; a fixing strap 7 for binding the swing rod 8 is fixed on the side wall of the sprayer body 4. The fixing strap 7 is an adjustable strap with a buckle. When the roller 9 swings to the front side of the sprayer body 4, the fixing strap 7 is bound to the vertical section of the swing rod 8, thereby fixing the vertical section of the swing rod 8 that has swung to the front side of the sprayer body 4; the fixing plate 11 is horizontally fixed on the horizontal section of the swing rod 8. A fastening screw is installed on the fixing plate 11, and a threaded hole for threaded engagement with the fastening screw is opened at the bottom of the base plate 1; Figure 6 and Figure 8 As shown, when this pesticide spraying device encounters flat farmland, it swings the swing rod 8 downwards, making the roller 9 vertically facing the ground. The roller 9 supports the pesticide spraying device, while the fixing plate 11 is attached to the bottom of the base plate 1, and the fastening screw is aligned with the threaded hole. Then, the fastening screw is rotated to make the fastening screw pass through the threaded hole, and the swing rod 8 is locked after swinging downwards. This solution constitutes a locking assembly for locking the swing rod 8 after swinging up and down. Of course, the locking assembly can also use hooks. Two hanging ears are fixed at the bottom of the base plate 1 and are arranged in a front-to-back interval. The hooks are hinged to the horizontal section of the swing rod 8. When the swing rod 8 swings in a certain direction, the hooks are hung on the hanging ears in the corresponding direction, thereby locking the swing rod 8 after swinging up and down.

[0028] A telescopic rod 6 is vertically fixed on the base plate 1, and a handle 5 is fixed to the top of the telescopic rod 6. Figure 1 , Figure 4 and Figure 7 As shown, the telescopic rod 6 includes an outer tube and an inner rod. The outer tube is vertically fixed to the base plate 1, and the inner rod is independently installed inside the outer tube. The handle 5 is fixed to the upper end of the inner rod. A top-pressing screw for locking the inner rod after movement is installed on the outer tube. When the swing rod 8 is extended, so that the roller 9 faces vertically to the ground, and the swing rod 8 is fixed, the operator can adjust the overall length of the telescopic rod 6 according to their own height. Then, the top-pressing screw is rotated so that the tip of the top-pressing screw presses against the inner rod, thereby locking the length of the telescopic rod 6 after extension. Therefore, by adjusting the length of the telescopic rod 6, it can accommodate operators of different heights, making the operation more comfortable for the operator.

[0029] The bottom of the base plate 1 has several evenly distributed support legs, such as... Figure 1 and Figure 2As shown, four support legs are fixed to the bottom of the base plate 1. The four legs are evenly distributed at the four corners of the bottom of the base plate 1. The four support legs create a gap between the swing rod 8 and the ground, and also support the base plate 1. The bottom of all the support legs is fixed with anti-slip pads. The anti-slip pads are made of materials such as rubber, silicone, and latex to increase the friction between the support legs and the contact surface (such as the ground, tabletop, and other flat surfaces) and prevent slipping.

[0030] To elaborate further, such as Figure 4 , Figure 5 and Figure 7 As shown, this embodiment preferably includes a guide rod 2, which is vertically fixed to the base plate 1 and the top of the base plate 1. The guide rod 2 and the telescopic rod 6 are aligned horizontally and parallel to each other. A sliding groove is provided on the wall of the guide rod 2, and a slider 12 that slides up and down along the inside of the groove is engaged in the groove. Figure 7 As shown, slider 12 is a T-shaped slider, and the slide groove is a T-shaped slide groove. Slider 12 and the slide groove are in a clearance fit, allowing slider 12 to slide up and down along the inside of the slide groove. A positioning screw for locking is mounted on slider 12, and a threaded hole for threaded engagement with the positioning screw is provided on the side wall of slider 12. When slider 12 moves up and down to a suitable position, the positioning screw is rotated so that its tip abuts against the wall of the slide groove, thus locking the moved slider 12. A mounting clip 3 for horizontally engaging the spray bar is fixed on slider 12, such as... Figure 1 , Figure 5 and Figure 7 As shown, the mounting clip 3 has a "C" shaped structure and is made of stainless steel, 65 manganese steel, and high-elasticity manganese steel sheet. The mounting clip 3 is fixed to the side wall of the slider 12. The spray bar on the sprayer body 4 is engaged with the mounting clip 3. The elastic clamping of the mounting clip 3 keeps the spray bar horizontal. During use, the operator can slide the slider 12 up and down according to the height of the plant, so that the slider 12 drives the spray bar to move up and down for adjustment. The slider 12 is locked with a positioning screw to lock the height of the spray bar, so as to adapt to different plant heights and allow the spray bar to spray pesticides on the plant from top to bottom. This solution constitutes a fixing component for fixing and adjusting the height of the spray bar on the sprayer body 4. Of course, the fixing component can also be a telescopic rod. The telescopic rod is vertically fixed to the top of the base plate 1, and the mounting clip 3 is fixed to the top of the telescopic rod. The spray bar of the sprayer body 4 is engaged with the mounting clip 3. The height of the spray bar can be adjusted by adjusting the telescopic rod up and down.

[0031] In practical use, when encountering flat farmland, the swing arm 8 can be swung downwards so that the roller 9 faces vertically towards the ground. Then, the fastening screw is turned to lock the fixing plate 11, thereby locking the swing arm 8 after it has swung downwards, allowing the roller 9 to support the pesticide spraying device. Afterwards, the operator adjusts the overall length of the telescopic rod 6 according to their own height, and engages the spray boom of the sprayer body 4 with the mounting clip 3. The slider 12 is then slid up and down according to the height of the plant, causing the spray boom to move up and down. The slider 12 is locked using positioning screws. When spraying pesticides, the worker holds the handle 5 at the top of the telescopic rod 6, then tilts the pesticide spraying device and pushes it in the direction of movement, causing the roller 9 to roll along the ground. During the transfer, the spray bar sprays pesticides onto the plants. The roller 9 supports the water tank, making the transfer process easier, reducing the worker's physical burden, preventing excessive depletion of their energy, and reducing labor intensity. When encountering farmland with complex terrain, such as... Figure 8 As shown, after the swing rod 8 swings upward, the vertical section of the swing rod 8 is aligned parallel to the front side wall of the sprayer body 4. The roller 9 is located on the front side of the sprayer body 4. The vertical section of the swing rod 8 is tied and fixed with the fixing strap 7. The spray bar is removed from the mounting clip 3. The two shoulder straps 10 on the sprayer body 4 are put on the shoulders of the worker, so that the sprayer body 4 is carried on the back of the worker, and the worker swings the spray bar to spray pesticides. The transfer method of this pesticide spraying device is switched in the above manner to adapt to farmland with different terrain environments.
