Description

Technical Field

[0001] This invention relates to the field of insecticide technology, and in particular to an automatic insect-attracting and insect-killing device. Background Technology

[0002] Sweet and sour solution is made by mixing sugar, vinegar, water, and alcohol in a certain proportion. When controlling pests in orchards, homemade sweet and sour solution is usually used to attract and kill pests. Fruit farmers hang the well-stirred sweet and sour solution on the trees through containers such as beverage bottles and small plastic basins. During use, fruit farmers need to check the situation of attracting pests frequently, remove the insects from the containers, and add solution in a timely manner.

[0003] To address the shortcomings of existing technologies that require fruit farmers to frequently check, remove insects from the pesticide solution, and add pesticides as needed, it is necessary to develop an automatic insect-attracting and killing device that can automatically add pesticides and separate insects. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an automatic insect-attracting and insect-killing device that can automatically add medicine and separate insect bodies.

[0005] The technical solution is as follows: An automatic insect-attracting and killing device includes a support frame, a liquid storage tank, a piston tube, a delivery tube, a piston rod, a hydraulic discharge rod, a torsion spring, an insect-killing cylinder, an insect-attracting opening, a liquid-discharging top rod, an electric push rod, and a liquid control mechanism. A liquid storage tank is fixedly connected to the upper side of the support frame, and the liquid storage tank and piston tube are also fixedly connected to the support frame. A delivery tube connects the piston tube and the liquid storage tank. A piston rod is slidably connected inside the piston tube. A hydraulic discharge rod is rotatably connected to the support frame, and the hydraulic discharge rod is slidably connected to the piston rod. A torsion spring connects the hydraulic discharge rod and the support frame. An insect-killing cylinder is located on the lower side of the support frame, and an insect-attracting opening is provided on the insect-killing cylinder. A liquid-discharging top rod is fixedly connected to the insect-killing cylinder. The liquid-discharging top rod drives the piston rod through the hydraulic discharge rod to inject insecticide into the insect-killing cylinder. An electric push rod is located on the lower side of the support frame to drive the insect-killing cylinder, and a liquid control mechanism is connected to the piston tube to control the flow of insecticide.

[0006] More preferably, the liquid control mechanism includes a water-discharging rod, a water-blocking block, and a water-blocking tension spring. The water-discharging rod is fixedly connected to the piston rod, and the water-blocking block is slidably connected to the piston tube. The water-blocking block is fitted with a water-blocking tension spring, and the water-blocking block has an inclined groove. The water-discharging rod passes through the inclined groove to allow the water-blocking block to release its obstruction of the insecticide liquid.

[0007] More preferably, it also includes a liquid discharge mechanism that can automatically discharge the old insecticide liquid in the insecticide cylinder. The liquid discharge mechanism is connected to the insecticide cylinder and includes a support rod, a support plate and a rubber sleeve. The support plate is fixed to the lower side of the support frame through the support rod, and a rubber sleeve for sealing the bottom of the insecticide cylinder is fitted on the support plate.

[0008] More preferably, it also includes a liquid-blocking mechanism to prevent the old and new insecticide solutions from mixing together. The liquid-blocking mechanism is connected to the insecticide cartridge and includes a liquid-blocking plate, a liquid-blocking spring, an inner inclined block, and an outer protruding rod. The liquid-blocking plate is slidably connected to the insecticide cartridge, and a liquid-blocking spring is connected between the liquid-blocking plate and the insecticide cartridge. An inner inclined block is fixedly connected to the liquid-blocking plate, and an outer protruding rod is fixedly connected to the support frame. The outer protruding rod, through the inner inclined block, causes the liquid-blocking plate to block the downward flow of new insecticide solution.

[0009] More preferably, it also includes a collection box and a flow guide for collecting old insecticide liquid. The collection box is fixedly installed on the lower side of the support frame, and the flow guide is fixedly connected to the upper side of the collection box. The flow guide is connected to the collection box.

[0010] More preferably, it also includes a cleaning mechanism for cleaning insects on the rubber sleeve. The cleaning mechanism is connected to the insecticidal cylinder. The cleaning mechanism includes a cleaning port, a cleaning rod, a cleaning torsion spring, a cleaning contact rod, a cleaning connecting rod, and a spiral guide rod. The guide shroud has a cleaning port, and the cleaning rod is rotatably connected to the guide shroud. A cleaning torsion spring connects the guide shroud and the cleaning rod. A cleaning contact rod is fixed to the cleaning rod. A spiral guide rod is fixed to the inner inclined block through the cleaning connecting rod. The spiral guide rod drives the cleaning rod to clean the insects on the rubber sleeve through the cleaning contact rod.

[0011] More preferably, it also includes a scraping ring for scraping and cleaning the inner wall of the insecticide cylinder, and the scraping ring is fixedly attached to the support plate.

[0012] More preferably, it also includes a sealing sleeve for increasing the sealing performance of the liquid baffle. The insecticide cartridge has a through hole, and the sealing sleeve is fixed to the through hole. The sealing sleeve covers the liquid baffle on the same side.

[0013] More preferably, it also includes a screen for screening insects, with the screen slidably connected to the collection box, and the screen having through holes to facilitate the leakage of insecticide liquid.

[0014] The beneficial effects are: 1. After the insecticide is stored in the storage tank in advance, the electric push rod drives the insecticide cylinder to move upward through a timer, so that the liquid outlet rod can deliver a quantitative amount of insecticide in the piston tube to the insecticide cylinder, realizing the function of automatically adding new insecticide in a quantitative manner, so that fruit farmers no longer need to frequently check the remaining amount of insecticide and add insecticide.

[0015] 2. The water-blocking block prevents the insecticide in the piston tube from flowing downwards, allowing the insecticide in the storage tank to be quantitatively injected into the piston tube.

[0016] 3. By installing a rubber sleeve at the bottom of the insecticide cylinder, the old insecticide solution can be automatically discharged when the insecticide cylinder moves upward, thus avoiding the mixing of new and old insecticide solutions and affecting the insecticidal efficiency.

[0017] 4. As the insecticide cylinder moves upward, the outward protruding rod closes the two baffles through the inner inclined block, so that when the old insecticide is discharged, the new insecticide can be carried on the upper side of the insecticide cylinder, which plays the role of isolating the old and new insecticides.

[0018] 5. The old insecticide solution flows into the collection box for collection, which makes it convenient for fruit farmers to uniformly treat the old insecticide solution. In addition, the insects can be filtered during the collection process. Even if the old insecticide solution is to be recycled, fruit farmers do not need to manually take the insects out of the old insecticide solution.

[0019] 6. The insecticidal cylinder moves the spiral guide rod upward, allowing the cleaning rod to clean the insects on the top of the rubber sleeve, preventing residual insects from contaminating the new insecticide solution or reducing the number of insects attracted and killed.

[0020] 7. As the insecticidal cylinder moves upward, the scraping ring can scrape and clean the inner wall of the insecticidal cylinder, and together with the cleaning rod, completely clean the insects remaining in the insecticidal cylinder. Attached Figure Description

Detailed Implementation

[0030] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0031] Example 1: An automatic insect-attracting and insect-killing device, such as Figure 1 and Figure 2As shown, the device includes a support frame 1, a storage tank 101, piston tubes 102, infusion tubes 103, piston rods 104, hydraulic discharge rods 105, liquid discharge torsion springs 106, insecticidal cartridges 107, insect attractant openings 108, liquid discharge push rods 109, electric push rods 110, and a liquid control mechanism. The storage tank 101 is fixedly connected to the upper side of the support frame 1. Two piston tubes 102 are symmetrically fixed to the support frame 1. An infusion tube 103 connects the piston tubes 102 and the storage tank 101. A piston rod 104 is slidably connected inside the piston tubes 102. Two hydraulic discharge rods 105 are symmetrically rotatably connected to the support frame 1. Each hydraulic discharge rod 105 has a slide rail, through which it slidably connects to the upper side of the piston rod 104 on the same side. Two hydraulic discharge rods 105 are symmetrically sleeved on their rotation shafts. A liquid-discharging torsion spring 106 is provided, with its two ends fixedly connected to a liquid-discharging hydraulic rod 105 and a support frame 1, respectively. An insecticidal cylinder 107 is provided on the lower side of the support frame 1, with two insect-attracting openings 108 symmetrically provided on the insecticidal cylinder 107. Two liquid-discharging top rods 109 are symmetrically fixedly connected to the top of the insecticidal cylinder 107. When the liquid-discharging top rods 109 move upward, they drive the liquid-discharging hydraulic rod 105 to rotate, thereby driving the piston rod 104 to inject the insecticidal liquid in the piston tube 102 into the insecticidal cylinder 107. Two electric push rods 110 are symmetrically provided on the lower side of the support frame 1, with the telescopic shafts of the electric push rods 110 facing upward and fixedly connected to the insecticidal cylinder 107. A liquid control mechanism is connected to the piston tube 102, which is used to control the outflow of insecticidal liquid in the piston tube 102.

[0032] When setting up this insecticidal device, it can be fixed or suspended from a tree using ropes or other securing structures. Then, the prepared insecticide solution is poured into the insecticidal cylinder 107 and the storage tank 101. Insects are attracted to the insecticide solution and fly into it through the insect-attracting opening 108, where they are killed. When there are a large number of insects in the solution, the electric push rod 110 extends. The extension of the electric push rod 110 can be controlled by a timer, a mature technology that will not be elaborated upon here. The electric push rod 110 pushes the insecticidal cylinder 107 upwards, causing the outlet rod 109 to rotate and drive the hydraulic rod 105 to rotate. The rotation of the hydraulic rod 105 causes the piston rod 104 to move downwards. During the downward movement of the piston rod 104, it blocks the infusion tube 103, causing the piston rod to... During the downward movement of piston rod 104, the insecticide cannot flow back into the storage tank 101. At the same time, piston rod 104 will drive the liquid control mechanism to no longer block the downward flow of insecticide in piston tube 102, so that the insecticide flows downward into insecticide cylinder 107. Then, control electric push rod 110 to retract and reset, thereby driving insecticide cylinder 107 to move downward. The liquid outlet rod 109 and the liquid outlet hydraulic rod 105 disengage. Then, the liquid outlet hydraulic rod 105 flips and resets under the action of liquid outlet torsion spring 106, thereby driving piston rod 104 to move upward and reset. When piston rod 104 resets, piston tube 102 will move above infusion tube 103, and the liquid control mechanism will start to block the downward flow of insecticide from piston tube 102. At this time, insecticide in storage tank 101 can flow into insecticide cylinder 107 through infusion tube 103.

[0033] like Figure 2 and Figure 3 As shown, the liquid control mechanism includes a drain rod 9, a water-blocking block 901, and a water-blocking tension spring 902. The drain rod 9 is fixedly connected to the bottom end of the piston rod 104. Two water-blocking blocks 901 are symmetrically slidably connected to the lower side of the piston tube 102. Two water-blocking tension springs 902 are symmetrically sleeved on the water-blocking blocks 901. The two ends of the water-blocking tension springs 902 are fixedly connected to the water-blocking blocks 901 and the piston tube 102, respectively. A sloped groove 903 is provided on the water-blocking block 901. When the drain rod 9 moves downward, it will cause the two water-blocking blocks 901 to move away from each other through the sloped groove 903.

[0034] When the piston rod 104 moves downward, it will cause the drain rod 9 to move downward. The drain rod 9 will squeeze the two water-blocking blocks 901 away from each other through the inclined groove 903 and stretch the water-blocking spring 902. Then, the insecticide in the piston tube 102 can flow out through the gap between the two water-blocking blocks 901. When the piston rod 104 moves upward, it will cause the drain rod 9 to move upward. When the piston rod 104 completes the reset, the drain rod 9 moves out of the inclined groove 903. The water-blocking spring 902 will drive the two water-blocking blocks 901 to move closer to each other and reset. The two water-blocking blocks 901 will close, thereby blocking the insecticide in the piston tube 102 from flowing out.

[0035] like Figure 5 and Figure 6 As shown, it also includes a liquid discharge mechanism that can automatically discharge the old insecticide liquid in the insecticide cylinder 107. The liquid discharge mechanism is connected to the insecticide cylinder 107. The liquid discharge mechanism includes a support rod 2, a support plate 201 and a rubber sleeve 202. The support rod 2 is provided on the lower side of the support frame 1. The support plate 201 is fixedly connected to the support rod 2. The rubber sleeve 202 is sleeved on the support plate 201. The rubber sleeve 202 can be inserted into the bottom of the insecticide cylinder 107 to play a sealing role.

[0036] When the insecticidal cylinder 107 moves upward, it will disengage from the rubber sleeve 202, so that the rubber sleeve 202 can no longer block the insecticidal liquid inside the insecticidal cylinder 107 from flowing out. When the insecticidal cylinder 107 moves downward, the rubber sleeve 202 will be inserted into the bottom of the insecticidal cylinder 107, thereby preventing the insecticidal liquid inside the insecticidal cylinder 107 from leaking out.

[0037] Example 2: Based on Example 1, such as Figure 1 , Figure 4 and Figure 7 As shown, it also includes a liquid-blocking mechanism to prevent the mixing of new and old insecticide solutions. The liquid-blocking mechanism is connected to the insecticide cylinder 107. The liquid-blocking mechanism includes a liquid-blocking plate 3, a liquid-blocking tension spring 301, an inner inclined block 302, and an outer protruding rod 303. Two liquid-blocking plates 3 are symmetrically slidably connected to the insecticide cylinder 107. Two liquid-blocking tension springs 301 are symmetrically sleeved on the liquid-blocking plates 3. The two ends of the liquid-blocking tension springs 301 are respectively fixed to the liquid-blocking plates 3 and the insecticide cylinder 107. The inner inclined block 302 is fixed to the ends of the two liquid-blocking plates 3 that are far apart from each other. Two outer protruding rods 303 are symmetrically fixed to the support frame 1. The outer protruding rods 303 can close the two liquid-blocking plates 3 through the inner inclined block 302, thereby blocking the downward flow of new insecticide solution.

[0038] As the insecticidal cylinder 107 moves upward, it drives the inner inclined block 302. The outer protruding rod 303, through the inner inclined block 302, presses the two liquid-blocking plates 3 toward each other and stretches the liquid-blocking spring 301. Before the insecticidal cylinder 107 disengages from the rubber sleeve 202, the two liquid-blocking plates 3 close. The closed liquid-blocking plates 3 prevent new insecticidal liquid from flowing downward, so as to facilitate the discharge of old insecticidal liquid. During the downward movement of the insecticidal cylinder 107, when the rubber sleeve 202 begins to be inserted into the bottom of the insecticidal cylinder 107, the inner inclined block 302 begins to disengage from the outer protruding rod 303. When the insecticidal cylinder 107 is completely reset downward, the inner inclined block 302 disengages from the outer protruding rod 303, and the liquid-blocking spring 301 drives the two liquid-blocking plates 3 to open, so that new insecticidal liquid can flow downward.

[0039] like Figure 5As shown, it also includes a collection box 4 and a flow guide 401 for collecting old insecticide liquid. The collection box 4 is fixedly installed on the lower side of the support frame 1, and the flow guide 401 is fixedly connected to the upper side of the collection box 4. The flow guide 401 is connected to the collection box 4. The electric push rod 110 is fixedly installed on the outside of the flow guide 401, and the support rod 2 is fixedly connected to the inside of the flow guide 401.

[0040] The old insecticide liquid in the insecticide cartridge 107 will flow into the collection box 4 through the guide hood 401 for collection and treatment.

[0041] Example 3: Based on Example 2, such as Figure 4 , Figure 6 and Figure 8 As shown, it also includes a cleaning mechanism for cleaning insects on the rubber sleeve 202. The cleaning mechanism is connected to the insecticidal cylinder 107. The cleaning mechanism includes a cleaning port 5, a cleaning rod 501, a cleaning torsion spring 502, a cleaning contact rod 503, a cleaning connecting rod 504, and a spiral guide rod 505. Two cleaning ports 5 are symmetrically opened on the flow guide 401. The cleaning ports 5 are at the same height as the top of the rubber sleeve 202. Two cleaning rods 501 are symmetrically rotatably connected to the flow guide 401. A cleaning torsion spring 502 is fitted on the cleaning rod 501. The two ends of the cleaning torsion spring 502 are fixedly connected to the flow guide 401 and the cleaning rod 501, respectively. A cleaning contact rod 503 is fixedly connected to the cleaning rod 501. A cleaning connecting rod 504 is fixedly connected to the inner inclined block 302. A spiral guide rod 505 is fixedly connected to the cleaning connecting rod 504. The spiral guide rod 505 drives the cleaning rod 501 to rotate through the cleaning contact rod 503. When the cleaning rod 501 rotates, it will sweep the insects on the rubber sleeve 202 into the collection box 4.

[0042] As the insecticide flows out of the insecticide cylinder 107, the gap between the cylinder 107 and the rubber sleeve 202 gradually widens. Therefore, some insects may adhere to the rubber sleeve 202 and the inner wall of the cylinder 107, contaminating the new insecticide. Furthermore, since some dead insects float on the insecticide, and the surface area of ​​the insecticide is fixed, the remaining insects reduce the number of insects attracted and killed. When the insecticide cylinder 107 moves upward or downward, it activates the cleaning rod 504, cleaning... During the upward movement of rod 501, spiral guide rod 505 will contact cleaning contact rod 503, and spiral guide rod 505 will cause cleaning rod 501 to rotate in the direction of guide shroud 401 through cleaning contact rod 503. Cleaning connecting rod 504 passes through cleaning port 5 and sweeps off the insects on top of rubber sleeve 202. When cleaning rod 501 rotates, it will store the cleaning torsion spring 502. When spiral guide rod 505 moves downward and disengages from cleaning contact rod 503, cleaning torsion spring 502 will drive cleaning rod 501 to reverse and reset.

[0043] like Figure 5 and Figure 8As shown, it also includes a scraping ring 6 for scraping and cleaning the inner wall of the insecticidal cylinder 107. The scraping ring 6 is fixedly connected to the support plate 201 and is in close contact with the inner wall of the insecticidal cylinder 107.

[0044] As the insecticidal cylinder 107 moves upward, the scraping ring 6 scrapes the insects on the inner wall of the insecticidal cylinder 107 onto the rubber sleeve 202, which, together with the cleaning rod 501, can completely clean the insects inside the insecticidal cylinder 107.

[0045] like Figure 5 and Figure 7 As shown, it also includes a sealing sleeve 7 for increasing the sealing performance of the liquid baffle 3. Two through holes are symmetrically opened on the insecticidal cylinder 107. The sealing sleeve 7 is fixed to the top and bottom walls of the through holes. The sealing sleeve 7 covers the liquid baffle 3 on the same side. The sealing sleeve 7 can be made of waterproof fabric such as nylon cloth or canvas.

[0046] The sealing sleeve 7 can increase the sealing between the liquid baffle 3 and the insecticide cylinder 107. When the two liquid baffles 3 are closed, the sealing sleeve 7 can fill the gap between the liquid baffle 3 and the insecticide cylinder 107, thereby increasing its sealing performance. When the two liquid baffles 3 are open, it can be seen from the figure that the side of the two sealing sleeves 7 that is close to each other will lose support, and thus deform under the gravity of the insecticide liquid, creating a gap between the two sealing sleeves 7, allowing the insecticide liquid to flow out.

[0047] like Figure 5 As shown, it also includes a screen 8 for screening insects. The screen 8 is slidably connected to the collection box 4, and the screen 8 has through holes to facilitate the leakage of insecticide liquid.

[0048] The sieve 8 can filter and separate the insects in the old insecticide solution, and can be pulled out from the collection box 4 so that the user can treat the old insecticide solution and the insects separately.

These descriptions are merely for explaining the principles of the embodiments of the present invention and should not be construed as limiting the scope of protection of the embodiments of the present invention in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the embodiments of the present invention.
