Description

Technical Field

[0001] This utility model belongs to the technical field of spray film device, and in particular relates to a spray film device for a biodegradable agricultural mulch film. Background Technology

[0002] The related technology discloses a biodegradable mulch film spraying device with announcement number CN222510014U. The device is equipped with a double-threaded rod. Specifically, the starting motor drives the worm gear to rotate, and the worm gear drives the double-threaded rod to rotate through the worm wheel. Since the double-threaded rod is double-threaded, when the double-threaded rod rotates, it will drive the two fixed seats to move closer or further apart, and in turn drive the two support legs and wheels to move closer or further apart. This design can adjust the distance between the wheels to adapt to different farmland conditions, and it is simple and convenient to operate.

[0003] However, since liquid mulch film raw materials are usually composed of a variety of chemical substances, the above-mentioned devices may not be able to fully stir the liquid mulch film raw materials during use. As a result, the various chemical substances in the liquid mulch film raw materials are not able to mix together fully, which may lead to local differences in the mechanical properties of the mulch film such as strength and toughness. Some parts are prone to breakage, affecting the overall use effect and service life of the mulch film. Utility Model Content

[0004] The purpose of this invention is to provide a spraying device for biodegradable agricultural mulch film. By incorporating a mixing section, when it is necessary to mix the liquid mulch film material inside the storage tank, the motor is first started. The motor drives the rotating shaft to rotate, which in turn drives the spiral stirring blades to mix the liquid mulch film material in the storage tank. During the mixing process, the liquid mulch film material impacts the arc-shaped seat and protrusions, turbulently changing the flow path of the liquid mulch film material. This ensures that the liquid mulch film material is fully and evenly mixed, preventing sedimentation or stratification, ensuring stable quality of the sprayed mulch film, and solving the problem of the difficulty in fully mixing various chemical substances in the liquid mulch film material.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a spraying device for biodegradable agricultural mulch film, comprising a vehicle body, a liquid storage tank mounted on the top of the vehicle body, and further comprising:

[0011] A flow-dispersing component is installed inside the liquid storage tank and is used to turbulent the liquid mulch film material inside the liquid storage tank.

[0012] A loading and unloading assembly is installed outside the liquid storage tank. The loading and unloading assembly is used to add liquid mulch film raw material into the liquid storage tank and to discharge liquid mulch film raw material.

[0013] The mixing and turbulence components work together to fully mix the liquid mulch film material in the storage tank.

[0014] Furthermore, the spraying unit includes a moving assembly mounted on the top of the vehicle body, the moving assembly being used to continuously change the spraying position of the liquid mulch film raw material during the spraying process; and

[0015] A drive assembly, mounted on the top of the vehicle body, is used to provide power to the moving assembly;

[0016] A transmission component is installed on the top of the vehicle body and is used to transport liquid mulch film material in the storage tank to the mobile component for spraying.

[0017] The moving components, driving components, and transmission components work together to enable the liquid mulch film material in the storage tank to be sprayed out in a fan-shaped motion trajectory.

[0018] Furthermore, the stirring assembly includes a motor mounted on the top of the storage tank, the output shaft of the motor being fixedly connected to a rotating shaft via a coupling, the bottom end of the rotating shaft extending into the interior of the storage tank and rotatably connected to the storage tank, and two spiral stirring blades being fixedly connected to the outer wall of the rotating shaft.

[0019] The motor is mounted on top of the liquid storage tank via bolts.

[0020] Furthermore, the flow-disrupting component includes an arc-shaped seat fixedly connected to the inner wall of the liquid storage tank, and a plurality of protrusions fixedly connected to the outer wall of the arc-shaped seat; and

[0021] The loading and unloading assembly includes a feed inlet fixedly connected to the top of the storage tank, a discharge pipe fixedly connected to the bottom of the storage tank, and a valve fixedly connected to the outer wall of the discharge pipe.

[0022] The turbulence-disrupting component consists of four sets. The four sets of arc-shaped seats are fixed to the inner wall of the liquid storage tank by welding, and the protrusions on the outer wall of the four sets of arc-shaped seats are also fixedly connected to the corresponding arc-shaped seats by welding.

[0023] Furthermore, the movable component includes a fixed base fixedly connected to the top of the vehicle body, a sector gear rotatably connected to the top of the fixed base, a movable plate fixedly connected to the top of the sector gear, and a nozzle mounted on the top of the movable plate.

[0024] The mounting bracket is fixed to the top of the vehicle body by welding.

[0025] Furthermore, the drive assembly includes a mounting slot formed on the top of the fixed base, an electric push rod is mounted on the front side of the fixed base, the rear end of the electric push rod extends into the interior of the mounting slot, a slide rod is fixedly connected to the inner wall of the mounting slot, a slider is slidably connected to the outer wall of the slide rod, a rack is fixedly connected to the top of the slider, and the rack meshes with a sector gear.

[0029] This utility model has the following beneficial effects:

[0030] 1. By setting up a mixing section, when it is necessary to mix the liquid mulch film material inside the storage tank, the motor is first started. The motor drives the rotating shaft to rotate, and when the rotating shaft rotates, it drives the spiral stirring blades to rotate and mix the liquid mulch film material in the storage tank. During the stirring process, the liquid mulch film material will hit the arc-shaped seat and the protrusion, which will turbulently move the liquid mulch film material and change the flow path of the liquid mulch film material, so as to fully mix the liquid mulch film material evenly, avoid the sedimentation or stratification of the liquid mulch film material, and ensure the stable quality of the sprayed mulch film.

[0031] 2. By setting up a spraying section, specifically during the spraying operation, the mixed liquid mulch film material in the storage tank is transported to the spray pipe through a water pump, connecting pipe, and hose. At the same time, the electric push rod is activated, which drives the slider and rack to move. The rack meshes with the sector gear, causing the moving plate and spray pipe to move back and forth in a sector trajectory. This allows the mulch film material to be evenly sprayed on the farmland surface, forming a protective film of relatively uniform thickness. This effectively avoids the problem of uneven spraying in certain areas. At the same time, the sector spraying method expands the coverage area and improves the efficiency of the spraying operation.

[0032] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
