Description

Technical Field

[0001] This utility model relates to the technical field of tea planting equipment, specifically a tea planting spraying device. Background Technology

[0002] According to patent authorization announcement number CN222532555U, a tea planting spraying device is disclosed. This utility model relates to the field of tea planting equipment technology, and its key technical points are: It includes a base plate, on which multiple support legs are fixedly installed, and each support leg has casters installed on its bottom surface. A control button is installed on one side of the top surface of the base plate, and a battery is installed on the other side of the top surface of the base plate. A suction pipe is installed at the input end of a water pump. Movable plates are slidably connected to the surfaces of multiple vertical rods. Spraying discs are connected between the inner walls of both ends of multiple U-shaped plates via bearings. An adjustment component is provided on the top surface of the movable plate, and a lifting component is provided on the top surface of the base plate. In this utility model, the nozzles can oscillate, thereby achieving spraying operations at different angles, greatly increasing the spraying coverage. The height of the multiple nozzles can be adjusted according to the height of the tea trees, allowing the nozzles to more comprehensively spray the tea leaves.

[0003] However, existing technologies have problems: current spraying discs use a two-by-two linkage angle adjustment mode, and individual spraying discs lack independent control functions. This design exposes significant drawbacks when facing the complex and varied terrain of tea-growing areas. In mountain tea gardens, the required spraying angles for pesticides differ drastically between tea trees at the top and bottom of the slope due to terrain differences. In terraced tea gardens, the height difference between different levels of tea ridges also requires precise matching of spraying angles. However, due to the limitations of existing adjustment mechanisms, spraying discs cannot flexibly adjust to different terrain features, often resulting in uneven pesticide coverage, local overspraying, or missed spraying. Especially in areas with large topographic relief, this limitation of adjustment makes it difficult for spraying discs to fully exert their effectiveness, which not only reduces pesticide utilization. Utility Model Content

[0004] The purpose of this invention is to provide a spraying device for tea cultivation, which solves the problem of the current spraying discs using a two-by-two linkage angle adjustment mode, where each individual spraying disc lacks independent control function. This design exposes significant drawbacks when facing the complex and varied terrain of tea-growing areas. In mountain tea gardens, the required spraying angles for pesticides differ drastically between tea trees at the top and bottom of the slope due to terrain differences. In terraced tea gardens, the height difference between different levels of tea ridges also requires precise matching of spraying angles. However, due to the limitations of the existing adjustment mechanism, the spraying discs cannot be flexibly adjusted to different terrain features, often resulting in uneven pesticide coverage, local overspraying, or missed spraying. Especially in areas with large topographic relief, this limitation of adjustment makes it difficult for the spraying discs to fully exert their effectiveness, which not only reduces the utilization rate of pesticides.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tea planting spraying device, comprising a cart, a water tank fixedly connected to the right side of the top of the cart, lifting brackets fixedly connected to both sides of the top of the cart, a lifting plate fixedly connected to the top of the lifting brackets, mounting frames fixedly connected to the four corners of the top of the lifting plate, a U-shaped plate provided at the top inside the mounting frame, a rotating shaft fixedly connected inside the U-shaped plate, the two sides of the rotating shaft being movably connected to the inside of the mounting frame, a locking mechanism fixedly connected inside the mounting frame, and a liquid supply mechanism fixedly connected to the right side of the top of the cart.

A water pump is connected to the left side of the water tank. The water pump is fixedly connected to the right side of the top of the lifting plate. The output end of the water pump is connected to a diverter block. A diverter pipe is connected to the surface of the diverter block. A spraying plate is connected to the side of the diverter pipe away from the diverter block. The surface of the spraying plate is fixedly connected to the outside of the U-shaped plate.

[0008] Preferably, vertical rods are fixedly connected to both sides of the bottom of the friction block, and the bottom of the vertical rods extends through to the bottom of the mounting frame.

[0020] 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.

[0021] Please see Figure 1-4A tea plantation spraying device includes a cart 1, a water tank 2 fixedly connected to the right side of the top of the cart 1, lifting brackets 3 fixedly connected to both sides of the top of the cart 1, a lifting plate 4 fixedly connected to the top of the lifting brackets 3, mounting frames 5 fixedly connected to the four corners of the top of the lifting plate 4, a U-shaped plate 6 provided inside the top of the mounting frame 5, a rotating shaft 7 fixedly connected inside the U-shaped plate 6, the two sides of the rotating shaft 7 being movably connected inside the mounting frame 5, a locking mechanism 8 fixedly connected inside the mounting frame 5, and a liquid supply mechanism 9 fixedly connected to the right side of the top of the cart 1.

[0022] Please see Figure 1-3 The locking mechanism 8 includes a locking wheel 81, which is fixedly connected to the surface of the rotating shaft 7. A friction block 82 is provided at the bottom of the locking wheel 81. An electric cylinder 83 is fixedly connected to the bottom of the mounting bracket 5, and the output end of the electric cylinder 83 is fixedly connected to the bottom of the friction block 82.

[0023] Furthermore, by setting the friction block 82, the angle of the spray plate 94 can be fixed. The electric cylinder 83 pushes the friction block 82 to rise and make close contact with the locking wheel 81. The friction force is used to lock the rotating shaft 7, ensuring that the angle of the spray plate 94 is stable during the spraying process and preventing the angle deviation caused by vibration and other factors from affecting the spraying effect.

[0024] Please see Figure 1-4 The liquid supply mechanism 9 includes a water tank 2, which is fixedly connected to the right side of the top of the trolley 1. A water pump 91 is connected to the left side of the water tank 2. The water pump 91 is fixedly connected to the right side of the top of the lifting plate 4. The output end of the water pump 91 is connected to a diverter block 92. A diverter pipe 93 is connected to the surface of the diverter block 92. A spraying plate 94 is connected to the side of the diverter pipe 93 away from the diverter block 92. The surface of the spraying plate 94 is fixedly connected to the outside of the U-shaped plate 6.

[0025] Furthermore, the distribution block 92 and the distribution pipe 93 ensure that the pesticide is supplied evenly and stably to each spraying plate 94, avoiding the problem of inconsistent local spraying volume caused by uneven liquid supply. At the same time, the spraying plate 94 is fixed to the outside of the U-shaped plate and works in conjunction with the angle adjustment structure of the spraying plate 94 to ensure effective spraying of pesticides even after the angle is adjusted, thereby improving the pesticide utilization rate and ensuring that the tea planting area receives comprehensive and uniform spraying treatment.

[0026] Please see Figure 1-3 Vertical rods 10 are fixedly connected to both sides of the bottom of the friction block 82, and the bottom of the vertical rods 10 extends through to the bottom of the mounting frame 5.

[0027] Furthermore, the vertical rod 10 ensures that the friction block 82 can move smoothly up and down under the drive of the electric cylinder 83, accurately contacting or separating from the locking wheel 81. On the other hand, the vertical rod 10 can enhance the stability of the friction block 82 during its movement, preventing it from shaking, thereby improving the reliability of the locking mechanism 8 and ensuring the normal operation of the angle locking and adjustment function of the spray plate 94.

[0028] Please see Figure 1 A sealing cover 11 is movably connected to the top of the water tank 2, and the sealing cover 11 is located on the right side of the water pump 91.

[0029] Furthermore, the sealing cap 11 can be opened when adding chemicals to the water tank 2 or when cleaning and maintaining the water tank 2. After the operation is completed, the seal is closed, which effectively prevents the chemical from evaporating and external impurities from entering the water tank 2 and contaminating the chemical, ensuring the quality and concentration stability of the chemical in the water tank 2, thereby ensuring the effectiveness and safety of the spraying operation.

[0030] Please see Figure 1 A handle 12 is fixedly connected to the right side of the water tank 2, and the handle 12 is located on the right side of the water pump 91.

[0031] Furthermore, the handle 12 facilitates the movement of the cart 1 in the tea garden by the operator, especially in tea garden environments with complex terrain and narrow spaces. It allows for more flexible control of the direction and position of the spraying device, improving the mobility of the equipment, reducing the labor intensity of the operator, and increasing the efficiency of spraying operations.

[0032] Please see Figure 1-2 A transparent plate 13 is fixedly connected to the right side of the water tank 2, and the transparent plate 13 is located to the left of the handle 12.

[0033] Furthermore, the transparent panel 13 allows operators to monitor the pesticide level at any time without opening the water tank 2, enabling timely replenishment and preventing interruptions in spraying operations due to insufficient pesticide. At the same time, the placement of the transparent panel 13 to the left of the handle 12 does not affect the operator's grip and operation of the handle 12, ensuring convenient observation while also considering the rationality and practicality of the overall equipment structure.

[0034] The specific implementation process of this utility model is as follows: When it is necessary to spray the tea leaves with pesticide, start the electric cylinder 83. The electric cylinder 83 drives the friction block 82 to move downward. The friction block 82 separates from the locking wheel 81. At this time, the rotating shaft 7, the U-shaped plate 6 and the spraying plate 94 can be rotated to adjust the angle. After the angle of the spraying plate 94 is adjusted, the friction block 82 can be reset. Each spraying plate 94 can be adjusted independently, so that the spraying plate 94 can better adapt to the changes in terrain. Start the water pump 91. The water pump 91 delivers the pesticide solution inside the water tank 2 to the inside of the spraying plate 94. The spraying plate 94 sprays the pesticide solution onto the tea leaves.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
