Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a herbicide spraying device. Background Art

[0002] Weed control has always been an important part of greening maintenance and management. Inadequate weed control will affect the growth and quality of plants. Weed control is generally achieved by spraying herbicides. Herbicides refer to agents that can kill weeds completely or selectively. They are a type of substance used to eliminate or inhibit plant growth. Commonly used varieties are organic compounds, which can be widely used to control weeds, shrubs, trees and other harmful plants in farmland, orchards, flower nurseries, grasslands and non-arable land, railway lines, rivers, reservoirs, warehouses, etc.

[0003] For example, a utility model patent with Chinese patent publication number CN219108575U discloses a biological herbicide spraying device, comprising: a main unit, including a base plate, on which a storage tank is provided; a spraying unit, including multiple rotating rods, on which a nozzle is fixedly connected, a hollow rod interspersed and rotating together with the storage tank and the base plate, multiple stirring rods rotatably interspersed on the hollow rod, multiple stirring blades fixedly connected to the stirring rod, a rotating assembly provided in the hollow rod, a motor provided at the bottom of the base plate, a reciprocating screw fixedly connected to the output end of the motor, and a swinging assembly provided between the reciprocating screw and the rotating rod.

[0004] During use, it was found that the above-mentioned prior art starts the motor to rotate the reciprocating screw, which drives the hollow rod to rotate, and the stirring rod to rotate, thereby stirring the solution in the storage tank horizontally. At the same time, the rotation of the stirring rod drives the stirring blade to rotate, stirring the solution vertically, so that the solution is stirred evenly to prevent it from settling. However, the nozzle sprays the herbicide in a horizontal state, so the herbicide is easily dispersed in the air after being sprayed, resulting in the herbicide being unable to cover the weeds on the ground well, affecting the weeding quality, and thus resulting in poor practicality. Utility Model Content

[0005] (1) Technical problems solved

[0006] In order to solve the above technical problems, the utility model provides a herbicide spraying device which is convenient for spraying, improves working efficiency and enhances practicality.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a herbicide spraying device, comprising a top plate, four legs evenly fixedly mounted on the bottom end of the top plate, casters fixedly mounted on the bottom ends of the four legs, a push handle fixedly mounted on the top plate, the adjustment mechanism comprising a lifting cover, two first support plates fixedly mounted on the bottom end of the top plate, slide grooves provided on the inner ends of the two first support plates, limit blocks fixedly mounted on both ends of the lifting cover, the two limit blocks are respectively slidably connected to the two slide grooves, a first motor is fixedly mounted on one of the first support plates, a rotating rod is fixedly mounted on the output end of the first motor, the other end of the rotating rod is rotatably connected to the other first support plate, two external threads with opposite rotation directions are provided on the rotating rod, sliders are screwed on the two external threads, and the top ends of the two sliders are respectively connected to the The top and bottom ends are fitted together, the bottom ends of the two sliders are hinged with connecting rods, and the other ends of the two connecting rods are hinged with the top of the lifting cover. The spraying mechanism includes a water tank, which is installed on the top plate through a connecting device. A water storage chamber is provided in the water tank, and a water inlet hole is provided at the top of the water storage chamber. A first water pipe is connected and installed at the bottom of the water storage chamber. A water pump is provided on the top plate. The first water pipe is connected to the input end of the water pump, and the output end of the water pump is connected to the second water pipe, and the output end of the second water pipe is connected to the third water pipe. A fourth water pipe is installed in the lifting cover, and the third water pipe is connected to the fourth water pipe. A plurality of nozzles are connected and installed on the fourth water pipe. The first water pipe and the second water pipe are both made of soft materials, the connection between the second water pipe and the water pump is made of hard material, and the third water pipe and the fourth water pipe are made of hard material.

[0009] By adopting the above technical solution, the top plate is moved to the place where spraying is required by casters, and the first motor is started. The first motor drives the rotating rod to rotate. Since the rotating rod is provided with two external threads with opposite rotation directions, when the rotating rod rotates, the sliders respectively screwed with the two external threads will approach or move away from each other. When the two sliders move away from each other, the top ends of the two connecting rods will move away from each other, so that the lifting cover drives the fourth water pipe and the nozzle to drop in height. After dropping to the appropriate height, the spraying mechanism is used for spraying. The lowered height can make the liquid medicine better contact with the weeds. At the same time, the lifting cover can prevent the wind from affecting the sprayed liquid medicine, thereby ensuring the spraying effect. This process realizes the process of facilitating spraying, improves work efficiency, and thus enhances practicality.

[0010] Furthermore, the connecting device includes two second support plates, both of which are fixedly installed at the bottom end of the water tank, and two fixing plates are fixedly installed on the top plate. Both fixing plates are provided with slots, and the two second support plates are respectively inserted into the two slots. Both fixing plates are provided with bolts, and the two bolts respectively fix the two second support plates.

[0011] By adopting the above technical solution, the water tank can be removed and inspected and cleaned by unscrewing the bolts. After the inspection is completed, the second support plate is inserted into the slot and re-fixed with bolts, thereby improving practicality.

[0012] Furthermore, two handles are fixedly installed on the water tank.

[0013] By adopting the above technical solution, when disassembling the water tank, the water tank can be conveniently removed by holding the handle, thereby improving the convenience of use.

[0014] Furthermore, a glass plate is provided on the lifting cover.

[0015] By adopting the above technical solution, the working condition of the nozzle can be observed through the glass plate, thereby improving safety.

[0016] Furthermore, a second motor is fixedly mounted on the water tank, and a stirring shaft is fixedly mounted on an output end of the second motor.

[0017] By adopting the above technical solution, after water and medicine are added to the water tank, the second motor is started, and the second motor drives the stirring shaft to rotate for rapid mixing, thereby improving practicality.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the present application provides a herbicide spraying device with the following beneficial effects:

[0020] The top plate is moved to the place where the medicine needs to be sprayed by the casters, and the first motor is started. The first motor drives the rotating rod to rotate. Since the rotating rod is provided with two external threads with opposite rotation directions, when the rotating rod rotates, the sliders screwed with the two external threads will approach or move away from each other. When the two sliders move away from each other, the top ends of the two connecting rods will move away from each other, so that the lifting cover drives the fourth water pipe and the sprinkler head to lower the height. After dropping to the appropriate height, the medicine is sprayed through the spraying mechanism. The lowered height can make the medicine liquid better contact with the weeds. At the same time, the lifting cover can prevent the wind from affecting the sprayed medicine liquid, thereby ensuring the spraying effect. This process realizes the process of facilitating spraying, improves work efficiency, and thus enhances practicality. BRIEF DESCRIPTION OF THE DRAWINGS

This motor is a well-known device purchased directly from the market by those skilled in the art. Here we only use it without making any structural and functional improvements to it. We will not go into details here. The motor is provided with a control switch matched with it. The installation position of the control switch is selected according to actual use requirements to facilitate the operator to operate and control. The first motor 8 drives the rotating rod 9 to rotate.
