Description

Technical Field

[0001] This utility model belongs to the field of grape cultivation technology and relates to spraying devices, specifically a spraying device for grape cultivation. Background Technology

[0002] A spraying device for grape cultivation is a type of agricultural machinery specifically designed for vineyards. It is primarily used for spraying pesticides, fertilizers, and other liquid products to control pests and diseases, promote growth, and increase crop yield. Spraying trucks are typically equipped with efficient spraying systems that can quickly and evenly distribute the pesticide solution onto the grapevines, ensuring that every leaf and fruit receives adequate protection. They also feature large water tanks to hold sufficient pesticide solution, making them suitable for large-scale vineyard operations. This reduces the frequency of pesticide application and increases work efficiency. They are usually driven by tractors or dedicated power units, allowing for flexible movement across various terrains and conditions. By using spraying trucks, grape growers can improve application efficiency, reduce labor intensity, and simultaneously contribute to improving fruit quality and yield.

[0003] However, some existing spraying devices for grape cultivation require workers to frequently add pesticides to the water tank. Frequent pesticide additions can lead to inaccurate dosage control, especially during busy periods, which can result in over- or under-dosing, affecting the effectiveness of the application and crop health. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a spraying device for grape cultivation. The technical problem to be solved by this utility model is that when using the spraying device, workers need to frequently add pesticides into the water tank. Frequent addition of pesticides may lead to inaccurate dosage control, especially under busy conditions, which may result in over- or under-dosing, affecting the application effect and crop health.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spraying device for grape cultivation includes a base, a support frame fixedly connected to the top of the base, two guide pipes symmetrically fixedly connected to the top of the support frame, two nozzles fixedly connected to the surface of each guide pipe, and an activation mechanism for activating the nozzles at one end of each guide pipe. A water tank is fixedly connected to the top of the base on the side away from the support frame, and four storage cylinders are fixedly connected to the top of the water tank in a ring-shaped arrangement. A first piston cylinder is fixedly connected to the top of each of the four storage cylinders, and a solenoid valve is fixedly connected to the bottom of each of the four storage cylinders. A piston rod is slidably connected inside each of the first piston cylinders, a piston disc is fixedly connected to the top of each of the four piston rods, and a first piston pad is fixedly connected to the bottom of each of the four piston discs. The piston discs and first piston pads are slidably connected inside the storage cylinders. A moving mechanism for moving the first piston pad is provided on the top of each of the four piston rods. By setting the piston pad, the pesticide dosage can be added according to the corresponding water volume.

[0007] As a further embodiment of this utility model, the starting mechanism includes a water pump, which is fixedly connected to the top of the base. One end of the water pump is fixedly connected to one side of the water tank, and the other end of the water pump is fixedly connected to a guide plate. A connecting pipe is fixedly connected to the surface of the guide plate near the guide pipe, and the other end of the connecting pipe is fixedly connected to one side of the guide pipe. By setting up the water pump, the nozzle can be started.

[0008] As a further embodiment of this utility model, the moving mechanism includes a second piston cylinder. A first one-way valve is fixedly connected to the surface of the first piston pad near the first piston cylinder. The other end of the first one-way valve is connected to one side of the first piston cylinder. A second one-way valve is fixedly connected to the surface of the second piston cylinder away from the first one-way valve. A third piston pad is slidably connected inside the second piston cylinder away from the storage cylinder. A float is fixedly connected to the bottom of the third piston pad. A second piston pad and a pull rod are fixedly connected to the top of the piston column. The pull rod is slidably connected to the top of the first piston cylinder. An adjustment mechanism for adjusting the float is provided on the top of the third piston pad. By setting the float, the third piston pad can be moved downward.

[0009] As a further embodiment of this utility model, the adjusting mechanism includes a limiting rod, which is fixedly connected to the inside of the second piston cylinder. The third piston pad and the float are slidably sleeved on the surface of the limiting rod. A spring is sleeved on the surface of the limiting rod.

A motor is fixedly connected to the top of the water tank, and a stirring rod is fixedly connected to the output shaft of the motor. An inlet pipe is provided on the surface of the water tank near the motor. The float can be reset by the spring.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model employs a piston pad to compress pesticides, allowing for precise pesticide dosage adjustment based on water volume. This effectively solves the problem of frequent pesticide additions to the water tank during spraying, which can lead to inaccurate dosage control, especially during busy periods, potentially resulting in over- or under-dosing and affecting application effectiveness and crop health. A first piston pad is installed at the top of the storage cylinder, contacting the gas via a second piston pad. As gas is continuously introduced, the second piston pad moves the first piston pad downwards. A solenoid valve is installed at the bottom of the storage cylinder; it opens when liquid is poured in, allowing pesticides to be added to the water tank as the first piston pad moves downwards. Since the downward movement of the first piston pad is determined by the upward movement of the third piston pad, pesticide dosage can be precisely measured according to the water volume.
