Description

Technical Field

[0001] This invention belongs to the field of forestry pest control technology, and in particular relates to a mobile smoke-generating and pesticide-dispensing device for the control of forest pests and diseases. Background Technology

[0002] With global climate change and ecological changes, the types of forest pests and diseases are increasing, posing greater challenges to prevention and control. Forest pest and disease control often uses fumigation to achieve the effects of frost protection and pest and disease control. Smoke agents have excellent diffusion and penetration capabilities, which can effectively cover densely vegetated areas, complex environments, and relatively enclosed spaces. The smoke particles are fine and can penetrate deep into the back of plant leaves, bark crevices, and other hidden parts to kill latent pests and pathogens.

[0003] The forage used for fumigation mainly includes flammable materials such as crop stalks, weeds, fallen leaves, mugwort, wheat straw, and fresh branches, which can produce a large amount of smoke. During the fumigation process, oxygen is the key factor for combustion. Sufficient oxygen can accelerate the oxidation reaction of the forage and reduce the black smoke and particulate matter produced by incomplete combustion. Existing smoke-generating and powder-discharging devices lack pretreatment of the forage. Some forage with high moisture content is difficult to burn completely. In addition, in order to increase the air circulation of the device, there may be a problem that the burning forage moves outward with the airflow, posing a safety hazard to the external forest environment. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing methods that lack pretreatment of forage, make it difficult for some high-moisture forage to burn completely, and cause burning forage to move outward with the airflow to increase air circulation in the device, posing a safety hazard to the external forest environment. Therefore, this invention proposes a mobile smoke-generating and pesticide-dispensing device for the prevention and control of forest pests and diseases.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mobile smoke-generating and spraying device for controlling forest pests and diseases includes a barrel body and a bottom net fixedly connected to the lower part of the barrel body's inner wall. A net barrel is snapped onto the upper part of the barrel body's inner wall. A piston plate is slidably connected to the inner wall of a square tube located below the net barrel. The output end of a motor fixedly connected to the outer surface of the barrel body extends into the interior of the square tube and is fixedly connected to a reciprocating screw. An eccentric wheel located inside the square tube is fixedly connected to the output end of the motor. A first one-way valve and a second one-way valve are respectively embedded in the inner bottom wall and inner top wall of the square tube. The eccentric wheel passes through the square tube and is slidably connected to a filter screen located at the lower part of the square tube. A nut threaded to the outer surface of the reciprocating screw is fixedly connected to the piston plate via a straight rod. A piston frame is slidably connected to the inner wall of a piston frame located below the filter screen. The piston frame is fixedly connected to the bottom surface of the filter screen via a vertical rod, and a telescopic spring is fixedly connected to the bottom surface of the piston frame. A blower is fixedly connected to the outer surface of the barrel body, and a heating wire located inside the barrel body is located to the right of the blower's air outlet.

[0006] As a further description of the above technical solution: The bottom end of the telescopic spring is fixedly connected to the inner bottom wall of the piston frame cylinder. The upper and lower ends of the vertical rod are fixedly connected to the filter screen and the piston frame respectively, and the vertical rod is slidably connected to the piston frame cylinder at the through point. The ball bearings rotatably connected to the upper surface of the filter screen are in contact with the outer surface of the eccentric wheel.

[0007] As a further description of the above technical solution: A set of first check valves embedded on the outer surface of the barrel are all connected to the interior of the piston frame cylinder, and a set of second check valves are embedded in the lower part of the inner wall of the barrel. A third check valve embedded in the bottom wall of the piston frame cylinder is connected to the second check valves.

[0008] As a further description of the above technical solution: The second check valve is located above the bottom mesh. The air inlet of the first check valve is connected to the outside, and the air outlet of the first check valve is connected to the air inlet of the third check valve. The air outlet of the third check valve is connected to the air inlet of the second check valve, and the air outlet of the second check valve is connected to the inside of the barrel.

[0009] As a further description of the above technical solution: The blower's outlet extends into the interior of the barrel. The heating wire is fixedly connected to the inner wall of the barrel, and the protective cover on the right side of the heating wire is engaged with the inner wall of the barrel. An oscillating motor is fixedly connected to the bottom surface of the bottom mesh.

[0010] As a further description of the above technical solution: The motor is rotatably connected to the barrel body through the passage, the slider fixedly connected to the outer surface of the nut is slidably connected to the inner wall of the groove opened in the inner wall of the square barrel, one end of the straight rod is fixedly connected to the nut, and the other end of the straight rod is fixedly connected to the piston plate.

[0011] As a further description of the above technical solution: The upper surface of the mesh bucket is fitted with a cover plate, and a handle is fixedly connected to the upper surface of the cover plate.

The feeding box door, the observation door, and the protective net are all in contact with the interior of the barrel.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In this invention, the combined use of a blower and heating wire can dry the straw on the surface of the bottom mesh, which is beneficial for the complete combustion of the straw. The operation of the motor drives the reciprocating screw to rotate, causing the nut to move the piston plate left and right on the inner wall of the square cylinder. During this process, the air inside the barrel flows to the outside through the filter screen, the first one-way valve, the square cylinder, the second one-way valve, the mesh barrel, and the cover plate. This increases the air circulation inside the device while slowing down the movement of the burning straw inside the barrel to the outside, thereby reducing the safety hazards to the external forest environment.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-6This invention provides a technical solution: a mobile smoke-generating and spraying device for forest pest and disease control, comprising a barrel body 1 and a bottom net 2 fixedly connected to the lower part of the inner wall of the barrel body 1. A cleaning box door 31 and a feeding box door 32 are snapped onto the front of the barrel body 1. The cleaning box door 31 is in contact with the interior of the barrel body 1. Disconnecting the cleaning box door 31 from the barrel body 1 facilitates cleaning of ash from the bottom wall of the barrel body 1. An observation door 33 is snapped onto the front of the feeding box door 32, and a protective net 34 is embedded in the front of the feeding box door 32. The feeding box door 32, the observation door 33, and the protective net 34 are all in contact with the interior of the barrel body 1. Disconnecting the feeding box door 32 from the barrel body 1 facilitates placing smoke-generating straw on the upper surface of the bottom net 2. Disconnecting the observation door 33 from the feeding box door 32 increases air circulation inside the barrel body 1. The protective net 34 prevents the straw inside the barrel body 1 from moving to the outside. The four corners of the bottom surface of the barrel body 1 are fixedly connected to... The device has casters 29 and a handle 30 fixedly connected to the outer surface of the barrel 1. The combination of casters 29 and handle 30 facilitates the movement of the device. A vibrating motor 24 is fixedly connected to the bottom surface of the bottom mesh 2. The vibrating motor 24 vibrates the bottom mesh 2, reducing the blockage of the bottom mesh 2 by the ash after the burning of the hay. This facilitates the operation of the blower 21 when it introduces air, increasing the air circulation inside the barrel 1. A mesh barrel 3 is clipped to the upper part of the inner wall of the barrel 1. A cover plate 27 is clipped to the upper surface of the mesh barrel 3. Different filter materials, such as stone particles and activated carbon particles, can be placed inside the mesh barrel 3 to filter the smoke flowing through it, reducing the impact of larger particles in the smoke on the external air environment. The cover plate 27 limits the filter materials inside the mesh barrel 3. A handle 28 is fixedly connected to the upper surface of the cover plate 27, which facilitates the disassembly and installation of the cover plate 27.

[0019] A piston plate 5 is slidably connected to the inner wall of the square tube 4 at the bottom of the mesh barrel 3. The output end of the motor 6, which is fixedly connected to the outer surface of the barrel 1, extends into the interior of the square tube 4 and is fixedly connected to a reciprocating screw 7. The motor 6 is rotatably connected to the through-hole of the barrel 1 to prevent friction between the output end of the motor 6 and the through-hole of the barrel 1. An eccentric wheel 8 is fixedly connected to the output end of the motor 6 inside the square tube 4. A set of first one-way valves 12 and second one-way valves 13 are respectively embedded in the inner bottom wall and inner top wall of the square tube 4. The air inlet of the first one-way valve 12 is connected to the interior of the barrel 1, and the air outlet of the first one-way valve 12 is connected to the air inlet of the second one-way valve 13. The air outlet of the second one-way valve 13 is connected to the interior of the mesh barrel 3, ensuring the airflow direction inside the square tube 4. That is, when the piston plate 5 reciprocates inside the square tube 4, the air inside the barrel 1 flows into the interior of the mesh barrel 3 through the filter screen 9, the first one-way valve 12, the square tube 4 and the second one-way valve 13.

[0020] An eccentric wheel 8 passes through a square tube 4 and is slidably connected to a filter screen 9 located at the lower part of the square tube 4. A ball bearing 35, rotatably connected to the upper surface of the filter screen 9, contacts the outer surface of the eccentric wheel 8. The ball bearing 35 reduces the friction between the eccentric wheel 8 and the filter screen 9, extending the service life of the filter screen 9. The eccentric wheel 8 does not contact the point where it passes through the square tube 4. A nut 10, threadedly connected to the outer surface of the reciprocating screw 7, is fixedly connected to the piston plate 5 via a straight rod 11. A slider 25, fixedly connected to the outer surface of the nut 10, is slidably connected to the inner wall of a groove 26 opened on the inner wall of the square tube 4. The cooperation between the slider 25 and the groove 26 limits the movement of the nut 10, allowing the nut 10 to move back and forth on the outer surface of the reciprocating screw 7 when the motor 6 drives the reciprocating screw 7 to rotate. One end of the straight rod 11 is fixedly connected to the nut 10, and the other end of the straight rod 11 is fixedly connected to the piston plate 5.

[0021] A piston frame 15 is slidably connected to the inner wall of the piston frame cylinder 14 at the lower part of the filter screen 9. The piston frame 15 is fixedly connected to the bottom surface of the filter screen 9 via a vertical rod 17, and a telescopic spring 16 is fixedly connected to the bottom surface of the piston frame 15. The upper and lower ends of the vertical rod 17 are fixedly connected to the filter screen 9 and the piston frame 15 respectively, and the vertical rod 17 is slidably connected to the through-hole of the piston frame cylinder 14 to prevent friction between the vertical rod 17 and the through-hole of the piston frame cylinder 14. The bottom end of the telescopic spring 16 is fixedly connected to the inner bottom wall of the piston frame cylinder 14. Figure 1 and Figure 6 All the telescopic springs 16 are in their natural state, and the telescopic springs 16 are configured to provide a reset for the piston frame 15.

[0022] A set of first check valves 18 embedded on the outer surface of the barrel 1 are all connected to the interior of the piston frame cylinder 14, and a set of second check valves 19 are embedded in the lower part of the inner wall of the barrel 1. A third check valve 20 embedded in the inner bottom wall of the piston frame cylinder 14 is connected to the second check valves 19. The second check valve 19 is located above the bottom mesh 2. The air inlet end of the first check valve 18 is connected to the outside, and the air outlet end of the first check valve 18 is connected to the air inlet end of the third check valve 20. The air outlet end of the third check valve 20 is connected to the air inlet end of the second check valve 19. The air outlet end of the second check valve 19 is connected to the interior of the barrel 1, which ensures the airflow direction inside the piston frame cylinder 14. That is, the outside air flows into the interior of the barrel 1 through the first check valve 18, the piston frame cylinder 14, the third check valve 20 and the second check valve 19, which further increases the airflow inside the barrel 1 and is conducive to the complete combustion of the straw on the upper surface of the bottom mesh 2.

[0023] A blower 21 is fixedly connected to the outer surface of the barrel 1, and a heating wire 22 is located on the right side of the air outlet of the blower 21 inside the barrel 1. The air outlet of the blower 21 extends into the interior of the barrel 1. The heating wire 22 is fixedly connected to the inner wall of the barrel 1, and a protective cover 23 on the right side of the heating wire 22 is engaged with the inner wall of the barrel 1. The protective cover 23 is designed to prevent external impurities from affecting the air outlet of the blower 21 and the heating wire 22. The combined arrangement of the blower 21 and the heating wire 22 can dry the straw on the upper surface of the bottom mesh 2, reduce the moisture on the outer surface of the straw, reduce the humidity of the burning straw, and facilitate the complete combustion of the straw.

[0024] The dried hay is placed on the upper surface of the bottom mesh 2 and the feed box door 32 is closed. The operation of the motor 6 drives the reciprocating screw 7 to rotate, causing the nut 10 to drive the piston plate 5 to move left and right on the inner wall of the square cylinder 4. During the process, the air inside the barrel 1 flows to the outside through the filter screen 9, the first one-way valve 12, the square cylinder 4, the second one-way valve 13, the mesh barrel 3 and the cover plate 27. This increases the air circulation inside the device and slows down the movement of the burning hay inside the barrel 1 to the outside, thereby reducing the safety hazards to the external forest environment. The rotation of the eccentric wheel 8 causes the filter screen 9 to vibrate, which reduces the clogging of the filter screen 9.

[0025] Working principle: During use, connect the motor 6, blower 21, heating wire 22, and oscillating motor 24 to the mobile power supply. The combined setting of blower 21 and heating wire 22 can dry the grass on the upper surface of the bottom net 2, which is conducive to the complete combustion of the grass. Place the dried grass on the upper surface of the bottom net 2 and close the feed box door 32. The operation of motor 6 drives the reciprocating screw 7 to rotate, so that nut 10 drives piston plate 5 to move left and right on the inner wall of square cylinder 4. During the process, the air inside the barrel 1 flows to the outside through filter screen 9, first one-way valve 12, square cylinder 4, second one-way valve 13, net barrel 3, and cover plate 27. While increasing the air circulation inside the device, it slows down the movement of the burning grass inside the barrel 1 to the outside, thereby reducing the safety hazards to the external forest environment. The rotation of eccentric wheel 8 causes filter screen 9 to vibrate, which reduces the clogging of filter screen 9.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
