Description

Technical Field

[0001] This utility model relates to the field of rotary spraying technology, and in particular to a multi-angle rotary spraying device for agricultural machinery. Background Technology

[0002] Spraying devices in agricultural planting are used to spray liquids such as pesticides, fertilizers, herbicides, or water, and are widely used in crop protection and growth management. A spraying device typically consists of a nozzle, pump, pipeline, and control system, capable of evenly distributing liquid and covering large areas of farmland. The use of spraying devices effectively improves the efficiency of crop pest and disease control, reduces manual labor intensity, improves the accuracy of application, and reduces resource waste. When spraying large areas of farmland, a multi-angle rotating spraying device for agricultural machinery is needed to improve work efficiency.

[0003] According to the Chinese patent "An Irrigation Device with Multi-Angle Spraying" authorized announcement number "CN219644730U", when the motor starts working, it drives the rotating disk on the output end surface to rotate, thereby driving the water pump to move through the inclined rod on the surface. At the same time, the slider on the surface is movably embedded in the sliding groove to further limit the water pump and prevent it from deviating from the direction during movement. Water is then drawn from the inside of the water tank through the three-way ball valve connected to one side surface and the water pipe connected to the other side, and sprayed through the top nozzle, thereby increasing the spraying area and reducing the workload.

[0004] Although the aforementioned application can drive the water pump to move by rotating the rotating disc, thereby driving the three-way ball valve and the nozzle to rotate and spray, the device can only effectively spray the top of the crop at a single angle when spraying crops, and cannot spray the roots of the crop. In addition, the working efficiency of a single nozzle is low when spraying.

[0005] Therefore, a multi-angle rotating spraying device for agricultural machinery is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-angle rotating spraying device for agricultural machinery to solve the above-mentioned problems, thereby improving the issues of single spraying angle and low spraying efficiency.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a multi-angle rotating spraying device for agricultural machinery, comprising: a base, wherein a water tank is fixedly connected to the upper surface of the base;

[0008] The spraying mechanism includes two diversion pipes that are connected to the water tank and fixedly connected to the upper surface of the base. Two arc-shaped nozzles are arranged opposite each other at the upper and lower ends of the diversion pipes. Two electric push rods are arranged opposite each other on the surface of the diversion pipes. The bottom end of the electric push rod is rotatably connected to the surface of the diversion pipe, and the driving end is hinged to the arc-shaped nozzle.

[0009] Preferably, both ends of the diverter pipe are rotatably connected to a rotating shaft, and connecting rods are fixedly connected to both sides of the rotating shaft. A limiting ball is rotatably connected between the two connecting rods and the arc-shaped nozzle. This facilitates the horizontal rotation of the arc-shaped nozzle.

[0010] Preferably, a drive motor is fixedly connected to the bottom end of the diverter pipe, the drive end of the drive motor is downwardly positioned and fixedly connected to a first gear, and a second gear is fixedly connected to the upper surface of the rotating shaft. The second gear meshes with the first gear, thereby driving the arc-shaped nozzle to rotate.

[0011] Preferably, four diversion blocks are fixedly connected to the inner wall of the diversion pipe. The four diversion blocks are arranged in pairs above and below the connection between the diversion pipe and the water tank. Each diversion block is a 120-degree sector-shaped block. This diversion is used to divert the water flow.

[0012] Preferably, two blocking blocks are disposed between the two diversion blocks, the blocking blocks being in contact with the diversion blocks, and the blocking blocks being 120-degree sector-shaped blocks. This makes the diversion more thorough.

[0013] Preferably, an adjusting tube is rotatably connected to the outer surface of the diverter, and the blocking block is fixedly connected to the inner wall of the adjusting tube. This facilitates adjustment.

[0014] Preferably, the surface of the arc-shaped nozzle is provided with multiple nozzles, and the nozzles are distributed at an angle of 180 degrees on the surface of the arc-shaped nozzle, thereby increasing the spraying area.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting a drive motor to drive the rotating shaft to rotate on the surface of the diversion pipe, the arc-shaped nozzle is driven to rotate laterally. By setting an electric push rod to drive the arc-shaped nozzle to rotate vertically in conjunction with the limiting ball, it can accurately spray according to the growth of different crops, increasing the diversity of spraying angles. At the same time, by setting arc-shaped nozzles at both ends of the diversion pipe, the top and roots of crops can be sprayed simultaneously, improving the work efficiency when spraying crops.

[0017] 2. By installing diversion blocks and blocking blocks inside the diversion pipe in conjunction with the regulating pipe, spraying can be done on the top of the crop only, the roots of the crop only, or both, depending on different needs. This increases the versatility of use while saving water and avoiding waste. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] In practical implementation: such as Figure 1-5 As shown, a multi-angle rotating spraying device for agricultural machinery includes: a base 100, and a water tank 200 is fixedly connected to the upper surface of the base 100.

[0026] The spraying mechanism 300 includes two diversion pipes 310 that are connected to the water tank 200 and fixedly connected to the upper surface of the base 100. Two arc-shaped nozzles 330 are arranged opposite each other at the upper and lower ends of the diversion pipes 310. Two electric push rods 340 are arranged opposite each other on the surface of the diversion pipes 310. The bottom end of the electric push rod 340 is rotatably connected to the surface of the diversion pipes 310, and the driving end is hinged to the arc-shaped nozzles 330.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the upper and lower ends of the diversion pipe 310 are rotatably connected to the rotating shaft 360. The two sides of the rotating shaft 360 are fixedly connected to the connecting rod 361. The two connecting rods 361 are rotatably connected to the arc-shaped nozzle 330 with the limiting ball 362. The bottom end of the diversion pipe 310 is fixedly connected to the drive motor 350. The drive end of the drive motor 350 is set downward and fixedly connected to the first gear 351. The upper surface of the rotating shaft 360 is fixedly connected to the second gear 352. The second gear 352 and the first gear 351 mesh with each other.

[0028] In this embodiment, the water pipe between the water tank 200 and the two diversion pipes 310 is a flexible hose, and a pressure boosting valve is provided at this location. The water flow can fill the diversion pipes 310 and provide pressure for spraying. The diversion pipes 310 are made of composite material, which can provide support for the components installed on the diversion pipes 310. The electric push rod 340 is connected to the diversion pipes 310 through a connecting block. The bottom end of the electric push rod 340 is fixedly connected to the connecting block, and the connecting block is rotatably connected to the surface of the diversion pipes 310. A ring is fixedly connected to the drive end of the electric push rod 340, and the ring is hinged to the crossbar provided behind the arc-shaped nozzle 330.

[0029] like Figure 3 Figure 4 and Figure 5 As shown, four diversion blocks 311 are fixedly connected to the inner wall of the diversion pipe 310. The four diversion blocks 311 are arranged in pairs above and below the connection between the diversion pipe 310 and the water tank 200. The diversion blocks 311 are 120-degree sector blocks. Two blocking blocks 321 are arranged between the two groups of diversion blocks 311. The blocking blocks 321 are attached to the diversion blocks 311. The blocking blocks 321 are 120-degree sector blocks. An adjusting pipe 320 is rotatably connected to the outer surface of the diversion pipe 310. The blocking blocks 321 are fixedly connected to the inner wall of the adjusting pipe 320. Multiple nozzles 331 are arranged on the surface of the arc-shaped nozzle 330. The distribution angle of the nozzles 331 on the surface of the arc-shaped nozzle 330 is 180 degrees.

[0030] In this embodiment, the width of the blocking block 321 is smaller than the width of the diverting block 311, and the interior of the diverting block 311 is hollow. The blocking block 321 is slidably connected to the inner wall of the diverting block 311. The two diverting blocks 311 of each diverting block 311 are fitted together, and the notches of the two diverting blocks 311 are staggered. The two blocking blocks 321 in the regulating pipe 320 are on the same vertical line. The middle part of the regulating pipe 320 has a 240-degree notch so that the regulating pipe 320 will not interfere with the water flow while rotating. The diverting pipe 310 has an annular groove on the movement trajectory of the blocking block 321. At the same time, it cooperates with the regulating pipe 320 to form a whole with the diverting pipe 310. The diverting pipe 310 is connected to the arc-shaped nozzle 330 through a hose. The hose needs to be reserved in length for the arc-shaped nozzle 330 to rotate.

[0031] When using this utility model, the water tank 200 needs to be filled with water first, and then the device is connected to the rear of the agricultural machinery. The water valve in the water tank 200 is turned on to start the agricultural machinery and spraying operation can begin.

[0032] The drive motor 350 is activated according to the distribution of crops. The drive motor 350 drives the first gear 351 to rotate, which in turn drives the second gear 352 to rotate. When the second gear 352 rotates, it drives the rotating shaft 360 to rotate on the surface of the diversion pipe 310. The rotation of the rotating shaft 360 drives the arc-shaped nozzle 330 to rotate, and at the same time drives the electric push rod 340 to rotate on the surface of the diversion pipe 310. When the nozzle 331 of the arc-shaped nozzle 330 is aligned with the crops, the electric push rod 340 is activated. The electric push rod 340 pushes the arc-shaped nozzle 330 to rotate up and down to adapt to crops of different heights.

[0033] When only the bottom of the crop needs to be sprayed, the regulating pipe 320 is rotated, which drives the blocking block 321 to rotate. When the blocking block 321 rotates to cooperate with the upper diverting block 311 to close the upper part of the diverting pipe 310, the water flow will only flow downwards through the lower nozzle 331 to spray the bottom of the crop. When only the top of the crop needs to be sprayed, the regulating pipe 320 is rotated in the opposite direction, which drives the blocking block 321 to cooperate with the lower diverting block 311 to close the lower part of the diverting pipe 310. This allows the water flow to only move upwards through the diverting pipe 310, thus achieving relatively precise spraying.

[0034] It should be noted that the drive motor 350 and electric actuator 340 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the drive motor 350 and electric actuator 340 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
