Description

Technical Field

[0001] The present invention belongs to the technical field of pest control, and particularly relates to a forest pest control device. Background Art

[0002] The principle of soil steam disinfection is to use high-temperature water vapor to disinfect the soil. By heating the soil to be treated with high-temperature steam for a long time, the soil is kept in a wet and hot state above 70 degrees Celsius for 30 minutes, so as to kill germs, insect eggs, weed seeds, etc. Soil steam disinfection destroys, inactivates or reduces harmful organisms such as germs, insect eggs and weed seeds in the soil through the heating effect of high-temperature steam, so as to achieve the purpose of disinfection. This method can not only solve the problem of continuous cropping of high-value crops, but also significantly improve the yield and quality of crops.

[0003] In the existing steam disinfection machine, when in use, steam is introduced into the soil through a steam pipe inserted into the soil to disinfect the soil. However, the number of steam outlets opened on the steam pipe is limited, and the output steam cannot quickly heat the surrounding soil, thus reducing the working efficiency of the control device. Therefore, we propose a forest pest control device to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that the number of steam outlets opened on the steam pipe of the existing steam disinfection machine is limited, and the output steam cannot quickly heat the surrounding soil, thus reducing the working efficiency of the control device.

[0005] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0006] A forest pest control device includes a steam generator, an output component for outputting steam, and a pressing mechanism that can press the output component downward into the soil. The output component includes an outer cylinder with a conical lower end and a movable tube movably installed inside the outer cylinder. The output end of the steam generator is fixedly connected with a conduit, and the conduit is connected to the upper part of the output component. A plurality of arc-shaped insertion tubes are fixedly installed on the movable tube, and the plurality of arc-shaped insertion tubes are communicated with the movable tube. Output ports are opened on each of the plurality of arc-shaped insertion tubes. Arc-shaped slots adapted to the arc-shaped insertion tubes are opened on the outer cylinder. A pulling mechanism for pulling the movable tube to move upward is arranged on the movable tube.

[0007] Further defined, the pressing mechanism includes a mounting plate and a hydraulic cylinder. The hydraulic cylinder is fixedly installed at the lower end of the mounting plate. A fixed cylinder is fixedly installed at the lower end of the mounting plate. A movable rod is movably installed in the fixed cylinder. A limit end is provided at the upper end of the movable rod. A compression spring is fixedly installed between the limit end and the inner wall of the fixed cylinder opening. A fixed cover is fixedly installed at the lower end of the movable rod. A bottom plate is fixedly installed at the lower end of the fixed cover. There are several groups of output components, and all are arranged at the lower end of the bottom plate. The bottom plate is fixedly connected to the upper end of the outer cylinder. With such a structural design, when the hydraulic cylinder works, it can push the fixed cover and the bottom plate downward, so as to push the output components downward into the soil. When the hydraulic cylinder retracts, the compression spring can drive the movable rod, the fixed cover and the bottom plate to return to the initial state, which is more convenient to use.

[0008] Further defined, the pulling mechanism includes a pull rod, a return spring, a grid plate and a hydraulic rod. The pull rod is fixedly installed at the upper end of the movable tube. The upper end of the pull rod penetrates through the bottom plate to the inside of the fixed cover. The conduit penetrates through the fixed cover and is connected to the pull rod. An air guide groove is provided in the pull rod. The conduit is connected to the movable tube through the air guide groove. An annular rib is fixedly installed at the upper end of the movable tube. The return spring is sleeved on the pull rod, and the return spring is located between the annular rib and the bottom plate. The grid plate is fixedly installed at the upper end of the pull rod. The grid plate is movably installed in the fixed cover. The hydraulic rod is fixedly installed on the fixed cover. The end of the hydraulic rod is fixedly connected to the upper end of the grid plate. With such a structural design, when the hydraulic rod works, it can drive the grid plate to move up or down, so as to facilitate the control of the working state of the output components.

[0009] Further defined, a retaining wall is fixedly installed near the edge at the lower end of the bottom plate. The retaining wall is made of elastic rubber. With such a structural design, when the retaining wall is close to the ground, the retaining wall can cover the steam escaping upward from the soil at this place to make full use of it.

[0010] Further defined, a bent plate is fixedly installed at the lower end of the hydraulic cylinder. A fixed seat is fixedly installed on the bent plate. A chute is opened inside the fixed seat. A driving ring and a driving gear adapted to the driving ring are movably installed in the chute. When the driving gear rotates, the driving ring reciprocates up and down in the chute. A push rod is fixedly installed at the lower end of the driving ring. The lower end of the push rod penetrates through the fixed seat. A motor for driving the driving gear to rotate is fixedly installed on the fixed seat. With such a structural design, when the motor works, the output shaft drives the driving gear to rotate, prompting the driving ring to reciprocate up and down in the chute, so as to continuously push the fixed cover and the bottom plate to move.

[0011] Further defined, a contact plate is fixedly installed at the lower end of the push rod, and the contact plate is in contact with the fixed cover. With such a structural design, the contact plate replaces the end of the push rod to contact the fixed cover, which can increase the contact area between the push rod and the fixed cover and has a protective effect on the fixed cover.

[0012] Further defined, the upper end of the mounting plate is fixedly connected to the steam generator, the lower end of the mounting plate is fixedly installed with a fixing frame through bolts, a tractor is provided at one end of the fixing frame, and a controller for controlling the operation of the steam generator, hydraulic cylinder, hydraulic rod and motor is arranged on the tractor. With such a structural design, the structure is simple and easy to use.

[0013] The invention adopting the above technical scheme has the following advantages:

[0014] 1. In the present invention, when the pulling mechanism drives the movable pipe to move upward, a plurality of arc-shaped insertion pipes will extend into the surrounding soil under the guidance of the arc-shaped insertion slots. At this time, the steam output by the steam generator is output outward through the conduit and the movable pipe, and will output steam into the soil through a plurality of steam output ports, so as to quickly heat the surrounding soil and improve the working efficiency of the prevention and control equipment.

[0015] 2. In the present invention, after the hydraulic cylinder drives the fixed cover and the bottom plate to be close to the ground, the bottom plate is retracted a set distance to be separated from the ground, and the lower end of the enclosure is closely attached to the ground. When the output component works and outputs steam into the soil, the enclosure can block the steam escaping upward and temporarily store it in the space enclosed by the bottom plate, the enclosure and the ground. When the motor works and drives the driving gear and the driving ring to move, the fixed cover and the bottom plate will make reciprocating up and down movements, continuously pushing the temporarily stored steam to the lower soil, making full use of the steam, thereby improving the soil steam disinfection efficiency.

A controller for controlling the operation of the steam generator 1, the hydraulic cylinder 31, the hydraulic rod 43 and the motor 56 is arranged on the tractor 61.

[0043] The usage method of the present invention is as follows:

[0044] During use, drive the tractor 61 to the forest area to be controlled. Control the hydraulic cylinder 31 to work through the controller. The hydraulic cylinder 31 pushes the fixed cover 34 and the bottom plate 35 downward. The compression spring 331 outside the movable rod 33 is in a compressed state at this time. The outer cylinder 21 at the lower end of the bottom plate 35 is inserted into the soil downward. When the outer cylinder 21 is completely immersed in the soil and the bottom plate 35 contacts the ground, the hydraulic cylinder 31 drives the fixed cover 34 and the bottom plate 35 to retreat a set distance upward, so that the lower end of the enclosure 351 is closely attached to the ground;

[0045] The hydraulic rod 43 works to drive the grid plate 42 to move upward, thereby driving the pull rod 4 to move the movable tube 22 of each output component 2 upward. The arc-shaped insertion tube 23 extends out under the guidance of the arc-shaped slot and is inserted into the surrounding soil. Then the steam generator 1 works. Steam is transported downward through the conduit 11 and the air guide groove of the pull rod 4 into the movable tube 22, and finally is output outward through the output port of the arc-shaped insertion tube 23, so that the steam is output into the surrounding soil to quickly heat the surrounding soil;

[0046] When the surrounding soil is heated by steam, the space enclosed by the enclosure 351, the bottom plate 35 and the ground blocks the steam escaping upward and temporarily stores it in this space. When the motor 56 works to drive the driving gear 54 and the driving ring 53 to move, the fixed cover 34 and the bottom plate 35 will reciprocate up and down, continuously pushing the temporarily stored steam to the lower soil. When the bottom plate 35 and the enclosure 351 move upward again, a negative pressure will be formed to drive the steam below to move upward, which can make the steam fully contact the surrounding soil, make full use of the steam, and thus improve the soil steam disinfection efficiency.

[0047] The above has introduced in detail a forestry pest control device provided by the present invention. The description of the specific embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
