Description

Technical Field

[0001] This utility model relates to the field of liquid fertilizer spraying technology, and more specifically, to a suspended liquid fertilizer spraying device. Background Technology

[0002] Liquid fertilizer spraying devices are agricultural equipment primarily used to evenly spray liquid fertilizer onto crops or soil. These devices play a vital role in improving fertilization efficiency and ensuring crops receive sufficient nutrients. There are various types of liquid fertilizer spraying devices, including handheld sprayers and backpack sprayers. Different types are suitable for agricultural production of different scales and needs, which can improve fertilization efficiency and accuracy, and help reduce waste and environmental pollution.

[0003] Existing liquid fertilizer spraying devices first store the liquid fertilizer in a large-capacity storage tank. This storage tank is designed to safely store large quantities of liquid fertilizer. When ready to spray, a pump is started to extract the liquid fertilizer from the storage tank and increase the pressure. The pressurized liquid fertilizer is then transmitted to the nozzle through a series of pipes and hoses. Upon reaching the nozzle, the liquid fertilizer is dispersed into fine particles or droplets through a specific design (such as slits or holes) and sprayed onto the crops. Liquid fertilizer spraying devices can effectively apply fertilizer to the target area, promoting crop growth while also improving fertilization efficiency.

[0004] In practical applications, existing technologies often require users to carry or manually transport liquid fertilizer of a certain weight when spraying crops in the field. This can lead to significant labor intensity and low efficiency for users on large farmlands. Therefore, a suspended liquid fertilizer spraying device is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a suspended liquid fertilizer spraying device. The entire spraying device is suspended from a tricycle frame via a U-shaped hanging rod. The device can be moved smoothly by the tricycle, allowing it to cover large areas of farmland and reducing manual operation time and labor intensity. It can also be suspended on a similar type of agricultural vehicle. In use, the two branch rods are rotated to the sides and extended from the main rod to form a single long rod, increasing the spraying area. After spraying, the branch rods are rotated to stand vertically upright, and then the rotating rod is rotated to fix the upright branch rods using pipe clamps, allowing it to be folded away and stored, reducing space requirements.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A suspended liquid fertilizer spraying device includes a U-shaped hanging rod. One end of the U-shaped hanging rod is fixedly connected to a main rod. The upper surfaces of both ends of the main rod are rotatably connected to branch rods via lugs and pins. Multiple pipe clamps are uniformly fixedly connected to the outer surfaces of the main rod and the branch rods. The inner cavity of each pipe clamp holds a metal hose, and the outer surface of the metal hose is connected to a delivery pipe.

[0010] Furthermore, there are two U-shaped hanging rods symmetrically arranged on the outer surface of the main rod, and both the main rod and the branch pipes are made of metal.

[0011] Furthermore, a rotating rod is hinged to the outer surface of the U-shaped hanging rod, and a pipe clamp is fixedly connected to one end of the rotating rod.

[0012] Furthermore, a piston is fixedly connected to the outer surface of the delivery pipe, and a liquid storage tank is movably connected to the outer surface of the piston.

[0013] Furthermore, the end of the delivery pipe furthest from the metal hose is located inside the liquid storage tank, and the delivery pipe is a hose.

[0014] Furthermore, a pump is installed on the outer surface of the delivery pipe, and the liquid storage tank is made of a transparent material.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution uses a U-shaped hanging rod to suspend the entire spraying device on the tricycle frame. The device can be moved smoothly by the tricycle. The device can cover a large area of ​​farmland by moving the device by the tricycle, reducing the time and labor intensity of manual operation. It can also be suspended on the same type of agricultural vehicle. When in use, the two branch rods are rotated to the sides to open and extend out from the main rod to form a long rod, increasing the spraying area. After spraying, the branch rods are rotated to make them stand vertically. Then, the rotating rod is rotated to fix the pair of upright branch rods through the pipe clamps and folded up to reduce the space occupied.

[0018] (2) In this scheme, the metal hose is fixed by clamping with two pipe clamps. Multiple nozzles are installed on the metal hose to spray crops. The metal hose has a certain degree of flexibility and can rotate with the branch rod. The nozzles atomize the liquid fertilizer and spray it onto the crops. At this time, the pump is started and the liquid fertilizer in the storage tank is pumped through the delivery pipe and delivered to each nozzle. The storage tank is sealed by the piston to ensure that no impurities enter. Attached Figure Description
