Technical Field
[0001] This utility model relates to the field of fruit tree planting and maintenance technology, specifically to a spraying and pruning device for fruit tree planting and maintenance. Background Technology
[0002] The spraying and pruning device for fruit tree planting and maintenance combines traditional spraying and pruning techniques to improve the efficiency of pesticide spraying and pruning. In addition, the device's functions can be extended to meet the needs of various crops, and improving the utilization rate of the device is the current design requirement and original intention.
[0003] Existing agricultural tools are limited in function, only capable of pruning or spraying pesticides, resulting in low utilization and efficiency. For example, a spraying and pruning device for maintaining fruit trees, disclosed in CN221634838U, includes a fixed beam. A bottom blade is fixedly installed on the left end of the fixed beam, with a water groove A on the front side of the bottom blade. A top blade is located above the bottom blade, and a water groove B is located on the back of the bottom blade. A support is fixedly installed on the upper left end of the fixed beam, and an L-shaped plate is fixedly installed on the right end of the top blade. The bottom right side of the L-shaped plate is hinged to the support. An arc-shaped beam is fixedly installed on the upper surface of the fixed beam, and a hydraulic cylinder is located above the arc-shaped beam. The right end of the hydraulic cylinder is hinged to the arc-shaped beam, and the left end of the hydraulic cylinder is hinged to the upper end of the L-shaped plate. Sleeves are fixedly installed on both the front and rear sides of the left end of the fixed beam, and each sleeve contains a one-way piston. This agricultural fruit tree maintenance spraying and pruning device, by setting up a bottom blade, a top blade, a sleeve, and a hydraulic cylinder, can achieve the effect of cutting branches while simultaneously caring for them. However, the cutting in this solution can only be done at a fixed point in one location, and batch pruning is not possible. Furthermore, the spraying of pesticides cannot cover a large area, resulting in poor efficiency in both pruning and pesticide spraying.
[0004] Therefore, it is necessary to invent a spraying and pruning device for fruit tree planting and maintenance to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a spraying and pruning device for fruit tree planting and maintenance, in order to solve the problem that existing spraying and pruning devices for fruit tree planting and maintenance have limited functions, such as only pruning or only spraying, resulting in low utilization.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A spraying and pruning device for fruit tree planting and maintenance includes a main body, a pesticide tank, and a spraying and pruning mechanism. The main body is equipped with a fixed frame, and the pesticide tank is placed inside the fixed frame. The spraying and pruning mechanism is connected to the main body, and a hoeing mechanism is also provided on the main body. The hoeing mechanism can be adjusted in angle by a rocker arm, which is equipped with a rod and a handle. The initial state of the hoeing mechanism is in contact with the bottom surface. The spraying and pruning mechanism is connected to the pesticide tank by a flexible hose.
[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0009] This invention, by installing a tilling mechanism on the main body of the device, enables the entire device to not only spray pesticides and prune crops during operation, but also to cultivate uncultivated land, saving time and energy, and significantly improving agricultural efficiency. The activation of the dual-head motor drives the cam to rotate, which in turn moves the moving rod, allowing multiple nozzles to swing around the collar, increasing the spraying area. Furthermore, the operation of the pruning blades at both ends, driven by the dual-head motor and sprocket, neatly trims branches and leaves protruding from the road, enhancing the overall practicality and utilization rate of the device.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0017] This utility model provides, for example Figures 1-5 The illustrated spraying and pruning device for fruit tree planting and maintenance includes a main body 1, a pesticide tank 3, and a spraying and pruning mechanism 4. A fixed frame 2 is mounted on the main body 1, and the pesticide tank 3 is placed inside the fixed frame 2. The spraying and pruning mechanism 4 is connected to the main body 1. A hoeing mechanism 5 is also mounted on the main body 1. The hoeing mechanism 5 can be adjusted in angle by a rocker arm 6, which is equipped with a rod 7 and a handle. The initial state of the hoeing mechanism 5 is in contact with the bottom surface. The spraying and pruning mechanism 4 is connected to the pesticide tank 3 by a flexible hose. An opening is provided inside the structure 4, and a cam 408 is connected inside the opening. A reset shaft 401 is installed on the spraying and trimming mechanism 4. The reset shaft 401 consists of a shaft and a spring. The end of the spring is fixedly connected to the moving rod 402. The moving rod 402 is hollow, and multiple crossbars 403 are fixedly connected through the moving rod 402. A nozzle 405 is installed on each of the multiple crossbars 403 through a collar 404. The crossbars 403 and the nozzles 405 are hinged together by a connecting rod. The collar 404 is fixedly connected to the spraying and trimming mechanism 4.
[0018] The hose on the medicine tank 3 is connected to the moving rod 402. The medicine is delivered from the moving rod 402 to the nozzle 405, so that multiple nozzles 405 can rotate and swing, increasing the spraying area.
[0019] A dual-head motor 406 is mounted on the back of the spraying and trimming mechanism 4. A cam 408 is connected to the dual-head motor 406 via a synchronous belt drive mechanism. The cam 408 is always in contact with the surface of the moving rod 402. Both ends of the drive shaft of the dual-head motor 406 are connected via sprockets to a chain with trimming blades 407 on its surface. The upper part of the chain is rotatably connected to the spraying and trimming mechanism 4 via sprockets. The height of the trimming blades 407 is adapted to the spraying and trimming mechanism 4.
[0020] When the dual-head motor 406 starts, multiple nozzles 405 can rotate and swing to increase the spraying area, while driving the operation of the trimming blades 407 to trim the branches and leaves extending out of the road neatly.
[0021] The main body 1 of the device is connected to the hoeing mechanism 5 by a connecting rod, and the end of the connecting rod is coaxial with the rocker arm 6. One side of the rocker arm 6 is a handle, and the shaft on the other side can extend into the shaft of the connecting rod. The connecting rod passes through a fixed plate, and the fixed plate has multiple holes 101, the diameter of which matches the diameter of the insertion rod 7. The hoeing mechanism 5 is located at the rear of the main body 1, and the driver's cab is located at the front of the main body 1.
[0022] When needed, the tilling mechanism 5 can naturally fall to the ground to till or turn the soil.
[0023] Working principle of this utility model:
[0024] Refer to the instruction manual appendix Figures 1-5 First, fill the pesticide tank 3 with the prepared or diluted pesticide solution, then connect the hose to the moving rod 402 in the pesticide tank 3 and the spraying and pruning mechanism 4. The entire device body 1 can be controlled to move forward and backward and control the direction through the cab in the main body 1.
[0025] When the main body 1 of the device is running, the hoeing mechanism 5 can be lowered or retracted (by inserting the rod 7 on the rocker arm 6 into the hole 101, the height of the hoeing mechanism 5 is fixed and it does not contact the bottom surface; when the rocker arm 6 is pulled out, the hoeing mechanism 5 will naturally fall to the ground or be fixed after being adjusted to a specified height, thus achieving the effect of hoeing or turning the soil); by starting the dual-head motor 406, the pruning blades 407 on both sides are driven to run, trimming the branches and leaves extending outside the road neatly, and simultaneously rotating the cam 408, so that the moving rod 402 is pushed to move back and forth, and the nozzle 405 will swing around the center of the collar 404, increasing the spraying area.
