[0040] A device for preventing cherry pests and diseases comprises an arc-shaped air guide housing 101, the outer wall of the arc-shaped air guide housing 101 is stepped, the outer diameter of the arc-shaped air guide housing 101 is proportionally reduced from bottom to top, a combustion chamber mechanism 200 is arranged at the bottom of the arc-shaped air guide housing 101, the combustion chamber mechanism 200 is matched with the inner wall of the bottom of the arc-shaped air guide housing 101, the combustion chamber mechanism 200 is used to burn dead branches and rotten leaves, and a smoke outlet 103 is opened at the top of the arc-shaped air guide housing 101, the smoke outlet 103 is used to discharge the internal combustion of the combustion chamber mechanism 200. The smoke generated during burning, the arc-shaped air guide shells 101 are provided with two, the two arc-shaped air guide shells 101 cooperate with each other, the two arc-shaped air guide shells 101 are closed to form a truncated cone structure, a vertically penetrating positioning tube structure 104 is formed inside after the two arc-shaped air guide shells 101 are closed, the positioning tube structure 104 is used to locate the position of the tree trunk, the bottom side of the two arc-shaped air guide shells 101 are jointly provided with a shell hinge 102, and the two arc-shaped air guide shells 101 are rotatably connected to each other through the shell hinge 102 provided at the bottom;

[0041] Among them, since the dead branches and rotten leaves that fall on the ground are prone to insect eggs and pathogens, the dead branches and rotten leaves on the ground are collected and placed inside the combustion chamber mechanism 200 before pruning the branches on the crown, and then the crown is pruned;

[0042] There are two purposes for setting the arc-shaped air guide housing 101 so that the outer diameter thereof is proportionally reduced from bottom to top. First, the bottom area of ​​the arc-shaped air guide housing 101 can be made larger, making it more stable and not easy to fall over. Second, setting the diameter of the smoke exhaust port 103 smaller can increase the speed of smoke being discharged from the smoke exhaust port 103, so that the smoke can be effectively sprayed on the crown of the cherry tree, thereby preventing the smoke from being unable to fully smoke the cherry tree.

[0043] The positioning tube structure 104 can be used to set the cherry tree inside. When the combustion chamber mechanism 200 burns, the high temperature can bake the inner wall of the positioning tube structure 104, so that the high temperature radiation can bake the surface of the cherry tree inside the positioning tube structure 104, thereby killing the germs and insect pests on the surface of the cherry tree.

[0044] The present invention can kill pathogens and insect eggs in the dead branches and rotten leaves by placing them inside the combustion chamber mechanism 200 for burning, and transmits the smoke generated by the combustion to the tree crown through the smoke exhaust port 103 to fumigate the tree crown to remove insects. At the same time, the wood ash generated by the combustion can kill the insect eggs and pathogens in the soil around the roots of the cherry tree, thereby achieving the effect of environmentally friendly killing of diseases and insect pests on the cherry tree. Moreover, since the dead branches and rotten leaves carrying diseases and insect pests are cleaned up, the diseases and insect pests are not easy to recur.

[0045] Furthermore, the combustion chamber mechanism 200 includes a combustion shell 201, an arc-shaped slot 202 and a cleaning pull ring 203. The combustion shell 201 has the same shape as the bottom of the arc-shaped air guide shell 101. The combustion shell 201 is a shell-shaped structure that is through from top to bottom. The combustion shell 201 is laterally plugged into the bottom side of the arc-shaped air guide shell 101. The arc-shaped slot 202 is arranged on one side of the combustion shell 201. The arc-shaped slot 202 is used to clamp the combustion shell 201 on the side of the positioning tube structure 104. The cleaning pull ring 203 is fixedly arranged on the side wall of the combustion shell 201 away from the arc-shaped slot 202. The cleaning pull ring 203 is arranged on the outside of the arc-shaped air guide shell 101.

[0046] Among them, the combustion shell 201 is penetrated from top to bottom only with the side wall, so that diseased branches can be thrown into the combustion shell 201 through the upper opening, and the burned wood ash can be dropped to the ground through the lower opening. At the same time, the combustion shell 201 can be matched with the arc-shaped air guide shell 101 and the positioning tube structure 104 to prevent the diseased branches from falling through the gap and failing to enter the combustion shell 201.

[0047] Furthermore, a combustion control mechanism 300 is laterally inserted into the bottom side of the arc-shaped air guide housing 101, and the combustion control mechanism 300 is arranged below the combustion chamber mechanism 200. The combustion control mechanism 300 comprises a control housing 301, an arc-shaped opening 302, an air supply hole 303, an air intake pipe 304 and a sealing cover 305. The arc-shaped opening 302 is opened on one side of the control housing 301, and the control housing 301 is clamped on the side of the positioning tube structure 104 through the arc-shaped opening 302. The air intake pipe 304 passes through the control housing 301. Aside from the arc-shaped opening 302, the sealing cover 305 is sleeved on the end of the air inlet pipe 304 outside the regulating shell 301, and the sealing cover 305 is used to seal the air inlet pipe 304. Three air inlet pipes 304 are provided, and the air inlet pipe 304 is used to control the oxygen supply inside the combustion chamber mechanism 200. The air supply holes 303 are opened through the upper surface of the regulating shell 301, and the upper surface of the regulating shell 301 corresponds to the combustion shell 201. The air supply holes 303 are used to transport oxygen for combustion to the inside of the combustion shell 201;

[0048] Among them, the control housing 301 of the combustion control mechanism 300 can be matched with the inner wall of the arc-shaped air guide housing 101 to prevent air from entering the combustion housing 201 from the gap around the control housing 301, causing the combustion control mechanism 300 to lose control of the combustion; at the same time, the arc-shaped opening 302 needs to be matched with the outer surface of the positioning tube structure 104 to prevent air from entering the control housing 301 from between the two, causing damage to the control function;

[0049] Among them, since the regulating shell 301 is arranged below the combustion shell 201, the ashes generated during combustion can easily enter the regulating shell 301 through the air supply hole 303, so the purpose of setting the arc-shaped opening 302 is mainly to pour the ashes entering the regulating shell 301;

[0050] When using the combustion control mechanism 300, a corresponding number of sealing covers 305 can be opened so that different numbers of air inlet pipes 304 can simultaneously supply gas to the interior of the combustion casing 201. In actual use, the combustion inside the combustion casing 201 needs to be controlled to a state where it can burn but cannot burn fully, so as to generate sufficient smoke to fumigate the tree crown to remove insects.

[0051] Furthermore, a smoke blocking mechanism 400 is laterally inserted into the bottom side of the arc-shaped air guide housing 101, and the smoke blocking mechanism 400 is arranged above the combustion chamber mechanism 200. The smoke blocking mechanism 400 comprises a smoke blocking plate 401, a smoke hole 402, a sealing strip 403, a smoke blocking handle 404 and an arc-shaped notch 405. The arc-shaped notch 405 is opened on one side of the smoke blocking plate 401, and the smoke blocking plate 401 is clamped on the side of the positioning tube structure 104 through the arc-shaped notch 405. The strip 403 is fixedly arranged on a side of the smoke blocking plate 401 away from the arc-shaped notch 405, and the sealing strip 403 is used to seal the gap between the smoke blocking plate 401 and the arc-shaped air guide housing 101. The smoke blocking handle 404 is fixedly connected to a side of the sealing strip 403 away from the smoke blocking plate 401, and the smoke blocking handle 404 is arranged outside the arc-shaped air guide housing 101, and the smoke blocking handle 404 is used to insert or withdraw the smoke blocking plate 401 from the arc-shaped air guide housing 101;

[0052] Among them, since the combustion process inside the combustion shell 201 is prone to high flames, high flames are easy to burst out from the smoke exhaust port 103 to burn the crown of the cherry tree. In order to prevent the high flames from causing damage to the cherry tree, a smoke blocking plate 401 with smoke holes 402 is provided, which can effectively prevent the height of the flames and does not affect the dissemination of smoke. At the same time, in order to prevent the combustibles inside the combustion shell 201 from being fully burned, a smoke blocking plate 401 with smoke holes 402 is provided on the top of the combustion shell 201. The smoke blocking plate 401 can further suppress the combustion of the combustibles, so that the combustibles no longer produce flames, but only produce smoke;

[0053] The smoke blocking mechanism 400 can be selected by the user according to specific circumstances during actual use. As an alternative auxiliary device, its actual use effect may deviate from the expected effect.

[0054] Further, the outer wall of the side of the arc-shaped air guide housing 101 is evenly and vertically provided with pedal holes 501, the pedal holes 501 correspond to the step setting of the arc-shaped air guide housing 101, the pedal holes 501 are used to climb the arc-shaped air guide housing 101, and the inner wall of the arc-shaped air guide housing 101 is rotatably installed with a baffle 502, the baffle 502 is correspondingly rotatably installed above the pedal hole 501, and the baffle 502 is used to cover the pedal hole 501;

[0055] Among them, since the diseased dead branches and rotten leaves are easy to fall to the ground, but the diseased fresh branches and leaves cannot fall off by themselves, the user can climb up to the trunk of the cherry tree through the pedal hole 501 set on the arc-shaped air guide shell 101 to prune the diseased and insect-infested branches. Since the fresh branches have more water inside, they cannot be fully burned in time after being put into the combustion chamber mechanism 200, so that the combustion can generate more smoke to smoke the tree crown;

[0056] Among them, since the pedal hole 501 is opened on the upper side of the arc-shaped air guide shell 101, smoke can easily overflow from the pedal hole 501, so a baffle 502 is rotatably installed inside it to prevent smoke from overflowing from the pedal hole 501, and when the user steps on the pedal hole 501, the baffle 502 can be pushed inward without affecting the use of the pedal hole 501.

[0057] Furthermore, the bottom inner wall of the arc-shaped air guide housing 101 is laterally fixedly connected with a support rod 600, and the support rod 600 is respectively arranged below the combustion chamber mechanism 200, below the combustion regulation mechanism 300 and below the smoke stifling mechanism 400, and the support rod 600 is used to support the combustion chamber mechanism 200, the combustion regulation mechanism 300 and the smoke stifling mechanism 400 respectively;

[0058] Among them, in order to prevent the support rod 600 from blocking the branches thrown into the smoke exhaust port 103, the number of support rods 600 is set as small as possible, preferably one or two. The function of the support rod 600 is to support the combustion chamber mechanism 200, the combustion control mechanism 300 and the smoke stifling mechanism 400 to make them reach a horizontal state.

[0059] Furthermore, a retaining ring 700 is fixedly connected to the bottom of the arc-shaped air guide housing 101, and the retaining ring 700 is arranged below the combustion control mechanism 300, and the retaining ring 700 is used to support and seal the bottom of the arc-shaped air guide housing 101;

[0060] Among them, the function of the retaining ring 700 is to guide the ashes inside the combustion shell 201 when they fall, so as to prevent the ashes from being blown away; when the trailer mechanism 800 is not used, the retaining ring 700 can also seal the bottom of the arc-shaped air guide shell 101 with the ground, so as to prevent air from entering the combustion chamber mechanism 200 from the bottom and affecting the regulating effect of the combustion control mechanism 300.

[0061] Furthermore, a trailer mechanism 800 is provided at the bottom of the arc-shaped air guide housing 101, and the trailer mechanism 800 is used to drag the arc-shaped air guide housing 101. The trailer mechanism 800 has a bearing ring 801 and a mounting ring 802. The upper surface of the bearing ring 801 is used to bear the arc-shaped air guide housing 101, and the mounting ring 802 is arranged below the bearing ring 801. The bearing ring 801 and the mounting ring 802 are the same semicircular structure and are arranged corresponding to each other. Universal wheels 804 are evenly installed on the lower surface of the mounting ring 802. The bearing ring 801 and the mounting ring 802 are arranged corresponding to each other. A trailer hinge 803 is provided on one side of the mounting ring 802, the two bearing rings 801 are rotatably connected to the two mounting rings 802 through the trailer hinge 803, positioning holes 807 are provided between the two bearing rings 801 and the two mounting rings 802, the positioning holes 807 are used to locate the position of the tree trunk, the end of the bearing ring 801 away from the trailer hinge 803 is fixedly connected to a tow rod 805, the side of the end of the tow rod 805 away from the bearing ring 801 is fixedly connected to a trailer handle 806, and the trailer handle 806 is used to drag the trailer mechanism 800;

[0062] Among them, the shell hinge 102 and the trailer hinge 803 are arranged on the same central axis, so that the opening angles of the load-bearing ring 801 and the arc-shaped air-guiding shell 101 are the same and can be opened at the same time. The positioning hole 807 has the same aperture as the positioning tube structure 104, and their function is to be able to place the trunk of the cherry tree therein.

[0063] A method for using the cherry pest prevention device comprises the following steps:

[0064] S1. Moving and installing equipment:

[0065] The arc-shaped air guide housing 101 is dragged around the cherry tree by using the universal wheel 804 provided at the bottom of the trailer mechanism 800, and then the two bearing rings 801 are opened around the trailer hinge 803 by holding the trailer handle 806, so that the two arc-shaped air guide housings 101 on the bearing ring 801 are also opened around the housing hinge 102, and then the opened arc-shaped air guide housing 101 is pushed toward the cherry tree, so that the positioning tube structure 104 and the positioning hole 807 can be sleeved on the cherry tree trunk, and then the two bearing rings 801 and the two arc-shaped air guide housings 101 are closed by using the trailer handle 806 to achieve the installation of the equipment;

[0066] The device can be selected according to the actual height of the cherry tree. When a small cherry tree is used for pest control, a small device can be selected. The small device is light in weight and does not require the trailer mechanism 800. It can be carried manually. A large cherry tree needs a large device for pest control. The large device is heavy in weight and needs the trailer mechanism 800 for towing.

[0067] S2. Trimming and burning preparation:

[0068] The combustion chamber mechanism 200 and the combustion control mechanism 300 are placed inside the arc-shaped air guide housing 101, and the smoke blocking mechanism 400 is taken out from the arc-shaped air guide housing 101. Then, the user climbs up to the crown of the cherry tree through the pedal hole 501 to prune the insect-infested branches and trunks. The pruned insect-infested branches and trunks are placed into the combustion housing 201 through the smoke exhaust port 103. The insect-infested dead branches and leaves on the ground can also be placed into the combustion housing 201.

[0069] When the branches are burned inside the combustion shell 201, a hot air flow is generated, and the hot air flow can drive the smoke to pass quickly through the smoke exhaust port 103. With the small size of the smoke exhaust port 103, the smoke can be discharged to a higher height, so that the cherry tree can be fully smoked.

[0070] S3. Combustion and smoke control:

[0071] The dead branches and leaves inside the combustion shell 201 are ignited, and the degree of fuel combustion inside the combustion shell 201 is controlled by controlling the opening amount of the air inlet pipe 304. When the combustion is incomplete, a large amount of smoke will be generated and discharged to the crown of the cherry tree through the smoke exhaust port 103; the burning flame inside the combustion shell 201 is covered by inserting the smoke smothering mechanism 400 into the arc-shaped air guide shell 101, thereby further preventing the combustion from supplying oxygen and increasing the amount of smoke generated;

[0072] The smoke-blocking mechanism 400 can be inserted into the arc-shaped air guide housing 101 as needed, and its main function is to suppress the smoke generated by combustion and prevent the height of the flame;

[0073] S4. Dust removal and equipment installation:

[0074] After the fuel in the combustion shell 201 is burned, the combustion control mechanism 300 is firstly pulled out from the arc-shaped air guide shell 101. As the combustion control mechanism 300 is no longer blocking the bottom of the combustion shell 201, the ash produced by the combustion falls onto the ground below the device. After the ash cleaning is completed, the load ring 801 and the arc-shaped air guide shell 101 are opened by the trailer handle 806 to separate the device from the cherry tree and move it.

[0075] Among them, when cleaning, there is no need to wait for the ash temperature to drop to normal temperature. It is best to choose to clean when the branches are completely burned and carbonized, but not fully burned, and there is a certain charcoal structure. At this time, the burning residues of the branches have a higher temperature and can still burn for a period of time. The high temperature of the burning residues can be used to bake the soil on the ground around the cherry tree at high temperature, so as to achieve high-temperature killing of insect eggs and pathogens hidden in the surface layer of the soil, and avoid recurrence of pests after the eggs are hatched; the ashes after burning are weakly alkaline, and can inhibit the growth of pathogens after mixing with the soil, and control the growth of harmful pathogens in the soil, providing an environmentally friendly and effective prevention and control plan for the prevention and control of diseases and insect pests of cherry trees.

[0076] The present invention can kill pathogens and insect eggs in the dead branches and rotten leaves by placing them inside the combustion chamber mechanism 200 for burning, and transmits the smoke generated by the combustion to the tree crown through the smoke exhaust port 103 to fumigate the tree crown to remove insects. At the same time, the wood ash generated by the combustion can kill the insect eggs and pathogens in the soil around the roots of the cherry tree, thereby achieving the effect of environmentally friendly killing of diseases and insect pests on the cherry tree. Moreover, since the dead branches and rotten leaves carrying diseases and insect pests are cleaned up, the diseases and insect pests are not easy to recur.

[0077] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0078] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
