Description

Technical Field

[0001] The utility model belongs to the technical field of spraying and weeding equipment, and in particular relates to a vehicle-mounted anti-collision electric spraying device. Background Art

[0002] As the length of my country's expressways continues to increase, road maintenance becomes increasingly important. Therefore, how to suppress the growth of weeds in the central divider and on the shoulders has become a key point in the field of expressway maintenance.

[0003] At present, weeding operations are divided into two methods: pesticide weeding and mechanical weeding. Among them, pesticide weeding is that the operator uses a handheld sprayer on a road maintenance vehicle to operate, and needs to follow the vehicle to ensure the safety of the vehicle and personnel during the spraying operation. Because the spray of the handheld sprayer is in a straight shape, the spraying area is narrow, the operation cycle is long, repeated spraying is required, and the herbicide is used more frequently. The operator directly contacts the medicine with the handheld sprayer or even inhales it into the nasal cavity, which not only leads to low weeding efficiency, but also poses a safety hazard to the operation. In addition, pesticide spraying on large areas of cultivated land or forest land can achieve the effect of weeding, but most pesticides cannot be degraded, and the residues in the soil will cause great damage to the soil. Mechanical weeding generally uses machinery to cut off the grass roots, and the resulting broken leaves are blown onto the road surface. Due to the strong airflow formed by high-speed vehicles, unsafe factors are increased, destroying the cleanliness of the road surface.

[0004] Therefore, faced with the problems of low efficiency, high weed control cost and high risk of spraying pesticides, the traditional road spraying method can no longer meet the needs of modern road maintenance. In order to improve the efficiency of maintenance operations, reduce energy consumption and environmental pollution, and improve operation safety, it is urgent to design a new, safe and efficient weed control device. Utility Model Content

The arc-shaped circular tube bracket realizes automatic obstacle avoidance and resetting through a two-way automatic return hinge. The arc-shaped circular tube bracket is located outside the vehicle compartment of the road maintenance vehicle, and is provided with a plurality of nozzles thereon. The plurality of nozzles are connected to the outlet of an electric water pump through a water outlet pipe, and the inlet of the electric water pump is connected to a liquid medicine storage container through a water inlet pipe.

[0007] As a further supplement to the above technical solution, the suspension bracket includes a first vertical rod and a second vertical rod. The first vertical rod and the second vertical rod are respectively installed on the outer and inner sides of the road maintenance vehicle through a longitudinal connecting rod across the car body railing, and the two-way automatic return hinge is arranged on the first vertical rod.

[0008] As a further supplement to the above technical solution, a first transverse limit rod and a second transverse limit rod are respectively fixed on the first vertical rod and the second vertical rod. The first vertical rod and the first transverse limit rod, and the second vertical rod and the second transverse limit rod form two cross structural planes. The two cross structural planes jointly clamp the suspension bracket on the car body guardrail of the road maintenance vehicle to prevent the suspension bracket from shaking back and forth during the spraying operation.

[0009] As a further supplement to the above technical solution, vertical quick clamps are respectively provided at both ends of the second lateral limit rod. The vertical quick clamps, in cooperation with the first vertical rod, squeeze and fix the suspension bracket on the carriage guardrail of the road maintenance vehicle to prevent the suspension bracket from swinging left and right during the spraying operation.

[0010] As a further supplement to the above technical solution, elastic sleeves are respectively provided at both ends of the second transverse limit rod, and the elastic sleeves are in contact with the car railing and cooperate with the vertical quick clamp to ensure the stability of the installation of the suspension bracket.

[0011] As a further supplement to the above technical solution, a sliding sleeve is movably arranged on the first vertical rod, a positioning bolt is arranged on the sliding sleeve, the two-way automatic return hinge is arranged on the sliding sleeve, and the arc-shaped circular tube bracket realizes the adjustment of the spraying height by moving the sliding sleeve up and down and locking it with the positioning bolt.

[0012] As a further supplement to the above technical solution, the arc-shaped circular tube bracket is fixed on a connecting rod, and the connecting rod is connected to a two-way automatic return hinge through a folding self-locking hinge. The arc-shaped circular tube bracket utilizes the folding self-locking hinge to achieve temporary locking and fixation at three rotation positions of 0°, 90°, and 180°.

[0013] As a further supplement to the above technical solution, the bidirectional automatic return hinge is a bidirectional spring hinge, and the hinge plates on both sides of the bidirectional spring hinge are respectively installed on one of the hinge plates of the sliding sleeve and the folding self-locking hinge.

[0014] As a further explanation and limitation of the above technical solution, the nozzle is a clip-on atomizing nozzle, which is installed on the arc-shaped circular tube bracket by using its own pipe clamp.

[0015] As a further supplement to the above technical solution, the nozzle has two interfaces, and the multiple nozzles are connected in series through multiple connecting pipes. The nozzles located on both sides of the arc-shaped circular tube bracket are respectively connected to the two interfaces of the three-way joint through a hose, and the third interface of the three-way joint is connected to the outlet of the electric water pump through a water outlet pipe, forming two liquid supply pipelines to provide high-pressure hydraulic power for the multiple nozzles.

[0016] As a further explanation and limitation of the above technical solution, the electric water pump is a high-pressure diaphragm pump.

[0017] As a further supplement to the above technical solution, the electric water pump is powered by either a generator or a battery.

The utility model utilizes a suspension bracket mounted on the railing of the road maintenance vehicle, and an arc-shaped circular tube bracket is arranged on the suspension bracket through a two-way automatic return hinge, and a plurality of nozzles are arranged on the arc-shaped circular tube bracket. During the spraying and weeding operation, the herbicide liquid in the liquid storage container is sprayed in a mist form evenly on the weeds in the isolation belt through an electric water pump, thereby realizing the vehicle-mounted automatic weeding operation. This can not only reduce energy consumption and make the spraying operation more efficient, thereby greatly improving the operation efficiency, reducing the number of operation days, and reducing the maintenance cost. The application of the two-way automatic return hinge enables the arc-shaped circular tube bracket to automatically avoid when encountering ground obstacles, and at the same time quickly reset, effectively preventing the nozzle from being damaged, which not only extends the service life of the electric spraying device, but also reduces the maintenance cost.

[0020] 2. The utility model can conveniently adjust the height of the arc-shaped round tube bracket through the combined design of the sliding sleeve and the positioning bolt to meet the spraying requirements of different heights. This design enables the electric spraying device to adapt to different working environments and working requirements, and improves the flexibility and accuracy of spraying.

[0021] 3. In the utility model, the two-way automatic return hinge and the nozzle are key components and are made of outsourced molded products. The standardized and modular design of these components makes installation and maintenance more convenient, and also reduces the difficulty of operation.

[0022] 4. The utility model adopts folding self-locking hinges to make the arc-shaped round tube bracket flexibly adjust the angle and fix it at three positions of 0°, 90° and 180°, so as to realize convenient folding and unfolding and improve work efficiency. At the same time, the overall structure is stable and reliable, the installation steps are simplified, and the outsourced molded products reduce the manufacturing cost.
