Description

Technical Field

[0001] The present invention relates to the field of forestry pest control equipment, and in particular to a fixed-point killing device for forestry pest control and a killing method thereof. Background Art

[0002] Forestry pest control refers to a comprehensive management technology for preventing and controlling forestry diseases and pests.

[0003] In recent years, forest pest and disease problems have become increasingly prominent in artificial plantations. The reason is that the tree species in artificial forests are single and their disease resistance is low. Therefore, treatment technologies such as chemical control and biological control have become key solutions for artificial forests to deal with pests and diseases. However, based on the control effect, it is not a sure win. The residues of pesticides such as chemical control will have toxic side effects on the trees themselves and surrounding organisms for a considerable period of time.

[0004] Biological control is to control the number of pests and diseases by introducing a large number of organisms that compete with pests and diseases. However, based on actual conditions, biological control has the disadvantages of periodicity and seasonality, that is, the climate has a linear relationship with the effectiveness of biological control.

[0005] Inspired by biological control, reducing the number of pests and diseases by arranging a large number of insect attractants is an important measure to overcome climatic conditions. However, from a practical point of view, the insect attractants need to be connected to the mains, that is, during the prevention and control process, corresponding infrastructure construction and manpower investment are necessary at the edge of the forest. Based on this, the existing insect attractants have limitations in use. Therefore, a pest killing device that does not require connection to the mains / external battery and can greatly reduce the number of maintenance times is the key to optimizing the above-mentioned insect attractants. Therefore, this application combines the above-mentioned key points and proposes a fixed-point killing device for forestry pest control. Summary of the Invention

[0006] The purpose of the present invention is to provide a fixed-point killing device and a killing method for forestry pest control to solve the above technical problems.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A fixed-point killing device for forestry pest control includes an evaporator with a accommodating chamber and a lifting assembly placed in the evaporator. The evaporator contains liquid. The lifting assembly includes a rod installed in the evaporator and a lifting block slidably sleeved on the rod. The rod stands vertically in the evaporator, and a diversion assembly is installed at the end of the rod away from the evaporator. The outer edge of the lifting block is slidably adapted to the inner wall of the evaporator for dividing the accommodating chamber into two upper and lower sealed chambers with variable sizes and volumes. The upper and lower sealed chambers with variable sizes and volumes are respectively provided with an insect attractant tube and a pulling member. The insect attractant tube is connected to the diversion assembly, and the pulling member passes through the lifting block and is connected to the insect attractant tube, so that the insect attractant tube expands outward or retracts inward relative to the evaporator when the lifting block moves up or down relative to the evaporator.

[0009] Preferably, the diversion assembly includes an insect attractant storage tank installed at one end of a rod and a sliding sleeve arranged at the bottom of the insect attractant storage tank. The insect attractant storage tank contains gelatinous insect attractant, and the sliding sleeve is provided with a diversion pipe. A floating platform is installed at one end of the diversion pipe located in the insect attractant storage tank, and the other end of the diversion pipe is connected to the side wall of the insect attractant tube, which is used to pull the floating platform into the gelatinous insect attractant when the insect attractant tube expands outward from the evaporation barrel, so that the gelatinous insect attractant slides into the insect attractant tube.

[0010] Preferably, the diversion tube is made of a soft material, and when the insect attractant tube is completely retracted into the evaporation barrel, the floating platform always floats above the liquid level of the gelatinous insect attractant.

[0011] Preferably, the rod includes a sliding rod standing vertically at the bottom of the evaporation barrel and a threaded rod installed on the upper end of the sliding rod. The threaded rod is the installation structure of the diversion assembly, which is used to support the diversion assembly so that the height of the diversion assembly is higher than the insect attracting tube.

[0012] Preferably, the sliding rod is slidably adapted to the lifting block, the threaded rod is threadedly connected to a limiting ring sleeve, and the position of the limiting ring sleeve to the threaded rod is the highest rising position of the lifting block.

[0013] Preferably, the maximum rising position of the lifting block does not exceed the top edge of the evaporation barrel.

[0014] Preferably, the pulling member includes a pulling tube connected to a port on one side of the insect attracting tube, and a counterweight block with a channel provided inside is installed on one end of the pulling tube away from the insect attracting tube, and the counterweight block is sunk into the liquid.

[0016] Preferably, the heating device includes a heating element sleeved on the barrel body and a solar panel attached to the surface of the heating element;

[0017] A pressure relief valve is provided above the barrier sleeve at the side wall of the barrel body.

[0018] A method for killing pests with a fixed-point killing device for forestry pest control, comprising the following killing steps:

[0019] 1) During sunlight exposure, solar energy is used to heat the liquid in the evaporation barrel to generate evaporation expansion pressure, causing the lifting block to move upward in the evaporation barrel. After moving to a certain position, the insect attractant tube pulled by the pulling member can expand outward relative to the evaporation barrel. During the outward expansion, a gel-based insect attractant is injected through the diversion component, luring flying insects into the insect attractant tube in the form of an odor signal, and causing the flying insects to adhere to the tube.

[0020] 2) After sunset, the expansion pressure in the evaporation barrel overflows at the gap between the lifting block and the inner wall of the evaporation barrel, causing the lifting block, which was originally moved upward by the expansion pressure, to slowly move downward relative to the rod. During the downward movement, the insect attractant tube retracts inward relative to the evaporation barrel. Under the residual temperature of the liquid and the action of gravity in the high-angle arrangement, the gelatinous insect attractant and flying insects fall into the liquid, thereby cleaning the insect attractant tube.

[0021] The beneficial effects of the present invention are:

[0022] The present invention provides an insect control treatment concept that combines obtaining kinetic energy, using kinetic energy to release insect attractants, and cleaning up the insect attractants and pests after the kinetic energy disappears. The treatment concept integrates main components such as an evaporation barrel, an insect attractant tube, a diversion assembly, and a lifting assembly. It aims to use solar energy to heat the liquid in the evaporation barrel, obtain evaporation expansion pressure during heating, and move the lifting block upward in the evaporation barrel. After moving to a certain position, the insect attractant tube dragged by the pulling member can expand outward relative to the evaporation barrel. During the outward expansion, a gelatinous insect attractant is injected through the diversion assembly to lure flying insects into the insect attractant tube in the form of an odor signal, and the flying insects are subjected to an adhesion treatment.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0031] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0032] Example 1

[0033] In this embodiment, a fixed-point killing device for forestry pest control is proposed, including an evaporation barrel 1 with a accommodating chamber and a lifting assembly 4 placed in the evaporation barrel 1. The evaporation barrel 1 contains liquid, and the lifting assembly 4 includes a rod installed in the evaporation barrel 1 and a lifting block 43 slidably sleeved on the rod. The rod stands vertically in the evaporation barrel 1, and a diversion assembly 3 is installed at the end of the rod away from the evaporation barrel 1. The outer edge of the lifting block 43 is slidably adapted to the inner wall of the evaporation barrel 1, and is used to divide the accommodating chamber into two upper and lower sealed chambers with variable sizes and volumes. The upper and lower sealed chambers with variable sizes and volumes are respectively provided with an insect trap 2 and a pulling member. The insect trap 2 is connected to the diversion assembly 3, and the pulling member passes through the lifting block 43 and is connected to the insect trap 2, so that the insect trap 2 expands outward or retracts inward relative to the evaporation barrel 1 when the lifting block 43 moves up or down relative to the evaporation barrel 1.

[0034] Please refer to Figure 1-6This embodiment provides an insect control treatment concept that combines the acquisition of kinetic energy, the use of kinetic energy to release an insect attractant, and the removal of the insect attractant and pests after the kinetic energy dissipates. This treatment concept integrates the main components such as the evaporation barrel 1, the insect attractant tube 2, the diversion assembly 3, and the lifting assembly 4. It is intended to use solar energy to heat the liquid in the evaporation barrel 1. During the heating period, the evaporation expansion pressure is obtained, causing the lifting block 43 to move upward in the evaporation barrel 1. After moving to a certain position, the insect attractant tube 2, which is dragged by the pulling member, can expand outward relative to the evaporation barrel 1. During the outward expansion, a gelatinous insect attractant is injected through the diversion assembly 3, luring flying insects into the insect attractant tube 2 in the form of an odor signal, and causing the flying insects to adhere to the insect attractant tube 2.

[0035] The working hours of the evaporation barrel 1 are closely related to sunrise and sunset. That is, after sunset, the expansion pressure in the evaporation barrel 1 overflows at the gap between the lifting block 43 and the inner wall of the evaporation barrel 1, causing the lifting block 43, which was originally moved upward by the expansion pressure, to slowly move downward relative to the rod. During the downward movement, the insect attractant tube 2 retracts inward relative to the evaporation barrel 1. Thereafter, under the residual temperature of the liquid and the action of gravity in the high-angle arrangement, the gelatinous insect attractant and flying insects fall into the liquid, thereby cleaning the insect attractant tube 2.

[0036] In addition, it should be noted that the insect attractant contained in the diversion component 3 is a colloid insect attractant, that is, the colloid insect attractant has poor fluidity and has excellent adhesion properties;

[0037] Among them, the poor fluidity is to avoid the problem of large amount of insect attractant leaking out after the insect attractant tube 2 pulls the diversion component 3 (the insect attractant needs to be used for a long time, thereby reducing the maintenance frequency);

[0038] The adhesion property is that after the flying insects enter the insect attracting tube 2, there is sufficient adhesion to attract the flying insects.

[0039] The following describes the installation and function of the subdivided structure of the killing device by setting up multiple implementation processes:

[0040] In a specific implementation, the diversion assembly 3 includes an insect attractant storage tank 31 installed at one end of a rod and a sliding sleeve 32 arranged at the bottom of the insect attractant storage tank 31. The insect attractant storage tank 31 contains colloid insect attractant. The sliding sleeve 32 is provided with a diversion pipe 34. One end of the diversion pipe 34 located in the insect attractant storage tank 31 is provided with a floating platform 33. The other end of the diversion pipe 34 is connected to the side wall of the insect attractant tube 2. When the insect attractant tube 2 expands outward relative to the evaporation barrel 1, the floating platform 33 is pulled into the colloid insect attractant, so that the colloid insect attractant slides into the insect attractant tube 2.

[0041] It should be noted that the diverter pipe 34 is made of soft material, and when the insect attractant tube 2 is completely retracted into the evaporation barrel 1, the floating platform 33 always floats above the liquid level of the colloid insect attractant.

[0042] like Figure 1 、 2 As shown in Figures 3, 4 and 5, how to guide the colloid attractant is to control the position of the floating platform 33 in the insect attractant storage tank 31. That is, when the floating platform 33 is located above the liquid level of the colloid attractant, it is difficult for the opening provided on the top of the floating platform 33 to draw the colloid attractant. Therefore, the colloid attractant is always stored in the tank. On the contrary, when the floating platform 33 sinks into the colloid attractant, the opening provided on the top of the floating platform 33 can serve as a passage to discharge the colloid attractant outward through the shunt pipe 34.

[0043] Based on this, the diverter pipe 34 is not only a pipeline for transporting the gelatinous insect attractant, but also a transmission structure for the control signal. That is, after the insect attractant tube 2 expands outward relative to the evaporation barrel 1, the insect attractant tube 2 applies a pulling force to the diverter pipe 34, causing the diverter pipe 34 to move downward relative to the sliding sleeve 32. As a result of the downward movement, the floating platform 33 is dragged into the gelatinous insect attractant, so that the gelatinous insect attractant is introduced into the insect attractant tube 2 along the diverter pipe 34.

[0044] In a specific implementation, the rod includes a sliding rod 44 standing vertically at the bottom of the evaporation barrel 1 and a threaded rod 41 installed at the upper end of the sliding rod 44. The threaded rod 41 is the installation structure of the diversion component 3, which is used to support the diversion component 3 so that the diversion component 3 is at a height higher than the insect attracting tube 2; in addition, the sliding rod 44 is slidably adapted to the lifting block 43, and the threaded rod 41 is threadedly connected to the limiting ring 42. The position of the limiting ring 42 to the threaded rod 41 is the highest rising position of the lifting block 43, but the maximum rising position of the lifting block 43 does not exceed the top edge of the evaporation barrel 1.

[0045] like Figure 1-3 As shown, the rod serves as a guide structure for the movement of the lifting block 43. First, it can limit the movement of the lifting block 43 to the up and down directions. Second, as the installation point of the diversion component 3, the height of the attractant tank 31 is higher than the height of the insect attractant tube 2, thereby facilitating the action of gravity on the gelatinous attractant, making it easier for the gelatinous attractant to fall into the insect attractant tube 2.

[0046] In addition, the threaded rod 41 itself has the function of limiting the upward movement of the lifting block 43, but considering that the rod diameter of the threaded rod 41 is vertically consistent with the rod diameter of the sliding rod 44, in order to prevent the lifting block 43 from entering the threaded rod 41, a limiting ring 42 is provided on the threaded rod 41 to control the movement range of the lifting block 43.

[0047] In a specific implementation, the pulling member includes a pulling tube 46 connected to a port on one side of the insect attracting tube 2. A counterweight 45 with a channel inside is installed at one end of the pulling tube 46 away from the insect attracting tube 2. The counterweight 45 is submerged in the liquid.

[0048] like Figure 3As shown, the pulling member passes through the lifting block 43 and is connected to the insect attracting tube 2. Based on this, the pulling member has multiple functions. First, it acts as a balancing structure to pull the insect attracting tube 2 and control the expansion range and relative position of the insect attracting tube 2. Second, it acts as a bridge for the insect attracting tube 2 to communicate with the liquid in the evaporating barrel 1. That is, one end of the pulling member sinks into the liquid, and the pressure in the insect attracting tube 2 will not be connected with the pressure in the evaporating barrel 1, ensuring that the environment in the insect attracting tube 2 is relatively peaceful. Third, the heat and humidity in the evaporating barrel 1 are slowly released layer by layer and then enter the insect attracting tube 2, creating an environment conducive to the reproduction of flying insects in the insect attracting tube 2 and assisting the colloid attractant. Finally, when the insect attracting tube 2 is retracted into the evaporating barrel 1, it acts as a conveying structure to guide the residual substances in the insect attracting tube 2 into the liquid to clean the insect attracting tube 2.

[0049] In a specific implementation, the evaporation drum 1 includes a drum body 13 for holding liquid and a heating device surrounded by the outer wall of the drum body 13. At least one side of the heating device faces the sun. A barrier sleeve 12 is installed inside the drum body 13. Above the barrier sleeve 12 is a movable cavity for the lifting block 43, and below the barrier sleeve 12 is a liquid holding cavity.

[0050] Specifically, the heating device includes a heating element 14 sleeved on the barrel body 13 and a solar panel 15 attached to the surface of the heating element 14; a pressure relief valve 11 is opened on the side wall of the barrel body 13 above the barrier sleeve 12.

[0051] like Figure 5 As shown, the barrel body 13 is heated by obtaining solar energy so that the liquid in the barrel body 13 is heated when the solar-driven heating element 14 releases heat energy. During the heating period, in order to avoid excessive expansion pressure in the barrel body 13, a pressure relief valve 11 is installed at the barrel body 13 to ensure that the pressure in the barrel body 13 approaches a safe value.

[0052] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
