Description

Technical Field

[0001] The invention relates to the technical field of garden pest control, in particular to a device for trapping and killing pests of garden trees. Background Art

[0002] With the acceleration of urbanization, the area of ​​gardening and greening is constantly expanding, and the prevention and control of pests and diseases of garden trees has become an important task. Although the traditional chemical pesticide control method is effective, long-term use will cause environmental pollution and destroy the ecological balance. Therefore, people have begun to explore more environmentally friendly pest and disease trapping technology. In addition to light trapping, there are also methods such as poison bait trapping, bait wood trapping, plant trapping and latent trapping. Poison bait trapping is to use the chemotaxis of pests, add appropriate poisons to their favorite food, and make various poison baits to trap and kill pests. Bait wood trapping is to use the habit of some pests to lay eggs and reproduce on newly felled fallen trees, and set up bait trees to trap and kill pests. Plant trapping is to use the habit of pests having a special preference for a certain plant, and trap and kill it after planting. At present, the device used to trap pests and diseases in gardens generally adopts a cylindrical design, and a hole with a larger outer diameter and a smaller inner diameter is provided at the top. An attractant is placed inside the device, and pests are attracted by the gas emitted by the attractant and enter the cylinder through these holes. Due to the design characteristics of the holes, pests are relatively easy to enter, but difficult to exit, thereby achieving the purpose of capturing pests. However, with the advancement of attractant technology, it has the ability to trap many different types of pests. However, the size of the holes at the top of the existing cylinder is fixed, and the capture effect of the smallest size of pests that can be attracted by the attractant is not ideal.

The area surrounded by the push plate, the transparent top plate and several partitions prevents the pests from escaping outward. At the same time, with the continuous rotation of the push plate, the area surrounded by the above three gradually shrinks from the outside of the cylinder toward the center of the cylinder, and the activity space of the pests also gradually shrinks accordingly, thereby prompting the pests to crawl into the through groove 2. The pests entering the through groove 2 then fall into the top of the piston plate in the inner cavity of the cylinder through the through groove 3, thereby completing the trapping of the pests. It should be noted that the width between the two adjacent partitions and the width of the corresponding through groove 1 can be shortened according to actual conditions, so as to achieve the trapping of smaller pests.

[0012] The present invention provides a garden tree pest trapping and killing device through improvement, which has the following improvements and advantages compared with the prior art:

[0013] 1. The area surrounded by the push plate, the transparent top plate and several partitions prevents pests from escaping. At the same time, as the push plate continues to rotate, the activity space of the pests gradually shrinks, which in turn causes the pests to fall into the top of the piston plate in the cylinder cavity, thereby completing the trapping of the pests.

[0014] 2. A small amount of powdered attractant stored in the storage bin will fall into the through slot 9 under the action of gravity, and the discharged gas can carry this part of the powder to adhere to the top of the cylinder, thereby enhancing the attraction effect on pests and diseases; in addition, since the gas circulates in the circulation chamber, the gas will carry a part of the water vapor when it is discharged from the circulation chamber, and this part of the water vapor will combine with the powdered attractant, making the powdered attractant more easily adhere to the top of the cylinder;

[0015] 3. The piston plate is blocked by the blocking rod when it moves downward. When the two adjacent springs are stretched or contracted to a certain extent, the blocking rod is forced to move toward the inside of the installation groove. At this time, the piston plate loses the blocking of the corresponding blocking rod and quickly moves downward for a distance, thereby achieving a pulse effect; and the gas pushed by the piston plate can also achieve a similar pulse effect. The pulsed airflow can carry the powdered attractant out of the through groove nine more quickly, thereby preventing the powdered attractant from clogging the through groove nine.

[0029] The present invention provides a garden tree pest and disease trapping and killing device through improvement. The technical solution of the present invention is:

[0030] like Figure 1-Figure 9As shown, a garden tree pest trapping device comprises a cylinder 1, and two symmetrical discharge troughs 19 are provided on the top of the cylinder 1. The garden maintenance personnel spread the attractant for attracting pests into the discharge trough 19 on the top of the cylinder 1; a motor 2 is fixedly installed at the bottom of the cylinder 1, and a cylinder 3 is fixedly installed at the output end of the motor 2, and the cylinder 3 extends upward to the top of the cylinder 1, and a shell 4 is fixedly sleeved on the top of the cylinder 1, and a circular plate 5 is welded on the top of the shell 4, and a push plate 6 is welded on the side wall of the circular plate 5, and a transparent top plate 36 is fixedly installed on the side wall of the push plate 6. A plurality of through slots 7 are evenly spaced on the side wall of the push plate 6, and a plurality of partitions 8 are welded on the top of the cylinder 1.

The motor 2 is set to drive the cylinder 3 rotates, and the cylinder 3 drives the shell 4, the circular plate 5, the push plate 6 and the transparent top plate 36 to rotate. At this time, the area surrounded by the push plate 6, the transparent top plate 36 and the plurality of partitions 8 makes it impossible for the pests to escape outward. At the same time, with the continuous rotation of the push plate 6, the area surrounded by the above three gradually shrinks from the outside of the cylinder 1 to the center of the cylinder 1, and the activity space of the pests also gradually shrinks accordingly, thereby prompting the pests to crawl into the through groove 2 9. The pests that enter the through groove 2 9 then fall into the piston plate in the inner cavity of the cylinder 1 through the through groove 3 10. 15 top, so as to complete the trapping of pests; it should be noted that, according to actual conditions, the width between two adjacent partitions 8 and the width of the corresponding through slot 1 7 can be shortened to achieve the trapping of smaller pests; wherein, a spring 34 is connected to the side wall of the push plate 6, and a slanted plate 35 is connected to the side of the spring 34 away from the push plate 6. During the rotation of the push plate 6, the slanted plate 35 is abutted against the outer wall of the shell 4 or the cavity wall of the through slot 2 9 under the elastic force of the spring 34, which further reduces the probability of pests escaping.

[0031] Furthermore, a threaded sleeve 11 is threadedly connected to the outer circumferential wall of the cylinder 3, and a ring body 12 is fixedly sleeved on the outer circumferential wall of the threaded sleeve 11. Two symmetrical mounting brackets 13 are welded on the left and right sides of the ring body 12, and a sliding rod 14 is welded between each two adjacent mounting brackets 13. A piston plate 15 is slidably arranged between the two sliding rods 14, wherein two symmetrical limiting rods 17 are welded between the upper and lower ends of the inner cavity of the cylinder body 1, and the piston plate 15 is slidably arranged between the two limiting rods 17, and the set limiting rods 17 can limit the piston plate 15 during the movement process; two springs 16 are wound around the outer circumferential walls of the two sliding rods 14, and a plurality of springs 16 are respectively connected between the corresponding mounting brackets 13 and the piston plate 15, so that the rotating cylinder 3 is brought The movable threaded sleeve 11 moves downward. It should be noted that a reciprocating threaded groove is provided on the outer circumferential wall of the cylinder 3, and the threaded sleeve 11 can move reciprocatingly up and down along the reciprocating threaded groove provided on the outer circumferential wall of the cylinder 3; the threaded sleeve 11 drives the ring body 12, the mounting frame 13, the slide rod 14 and the piston plate 15 to move downward, so that the gas at the lower part of the piston plate 15 enters the circulation chamber 18 through the through groove four 20; the bottom of the inner cavity of the cylinder 1 is separated by a circulation chamber 18, and the inner cavity wall of the circulation chamber 18 is provided with a through groove four 20, a through groove five 21 and a through groove six 22, and the outer circumferential wall of the cylinder 3 is provided with two symmetrical through grooves seven 23 and through groove eight 24, and the through groove eight 24 penetrates the cavity wall of the cylinder 3 and extends to the inner cavity of the shell 4, and the outer circumferential wall of the shell 4 is provided with a through groove Slot nine 25, and the through slot nine 25 penetrates the cavity wall of the shell 4 and extends to the outside of the shell 4, a storage bin 26 is fixedly installed on the top of the circular plate 5, and the bottom of the storage bin 26 is connected with the through slot nine 25, and the gas enters the inner cavity of the cylinder 3 through the through slot four 20, the through slot five 21, the through slot six 22 and the through slot seven 23 in turn, and finally the gas is discharged from the inner cavity of the shell 4 through the through slot eight 24 and the through slot nine 25 in turn. In this process, a small amount of powdered attractant stored in the storage bin 26 will fall into the through slot nine 25 under the action of gravity, and the discharged gas can entrain this part of the powder to adhere to the top of the cylinder 1, so as to enhance the attraction effect on pests and diseases; in addition, since the gas circulates in the circulation cavity 18, the gas is discharged from the circulation cavity. At 18 o'clock, a part of water vapor will be entrained, and this part of water vapor will combine with the powdered attractant, making the powdered attractant easier to adhere to the top of the cylinder 1; wherein, an air outlet balance pipe 30 and an air inlet balance pipe 31 are connected on the outer peripheral wall of the cylinder 3, and an air outlet balance check valve 32 and an air inlet balance check valve 33 are fixedly installed on the walls of the air outlet pipe and the air inlet pipe, respectively, when the piston plate 15 that has moved down to the bottom moves up and resets, the arranged air outlet balance check valve 32 and the arranged air inlet balance check valve 33 respectively assist the cylinder 1 to discharge and inhale air, so as to ensure the stability of the air flow passage when the piston plate 15 moves up and resets; it should be noted that when the piston plate 15 moves down, the arranged air outlet balance check valve 32 and the arranged air inlet balance check valve 33 are both kept in a closed state;

[0032] Furthermore, a plurality of mounting grooves 27 are provided on the inner circumferential wall of the cylinder body 1, and a plurality of springs 28 are connected to the inner cavity walls of the plurality of mounting grooves 27, and a baffle 29 is connected to the side of the plurality of springs 28 away from the inner cavity wall of the mounting groove 27. The piston plate 15 is blocked by the baffle 29 when it moves downward. When two adjacent springs 16 are extended or retracted to a certain extent, the baffle 29 is forced to move toward the inside of the mounting groove 27. At this time, the piston plate 15 loses the obstruction of the corresponding baffle 29 and moves downward quickly for a distance, thereby achieving a pulse effect; thereby, the gas pushed by the piston plate 15 can also achieve a similar pulse effect, and the pulsed airflow can more quickly carry the powdered attractant out of the through groove 9 25, thereby preventing the powdered attractant from clogging the through groove 9 25.

[0033] Working principle: Before use, the installation column for fixing the main body of the device is fixedly inserted into the designated position inside the garden, and then the main body of the device is fixedly installed on the top of the outer peripheral wall of the installation column with the help of screws. Then the garden maintenance personnel will spread the attractant used to attract pests and diseases into the discharge trough 19 at the top of the cylinder 1; when in use, under the attraction of the smell of the attractant, the pests and diseases will gather in the top area of ​​the cylinder 1, and the motor 2 will drive the cylinder 3 to rotate, and the cylinder 3 will drive the shell 4, the circular plate 5, the push plate 6 and the transparent top plate 36 to rotate. At this time, the area surrounded by the push plate 6, the transparent top plate 36 and several partitions 8 makes it impossible for the pests and diseases to escape outwards. At the same time, with the continuous rotation of the push plate 6, the above three The enclosed area gradually shrinks from the outside of the cylinder 1 to the center of the cylinder 1, and the activity space of the pests and diseases also shrinks accordingly, thereby prompting the pests and diseases to crawl into the through groove 2 9. The pests and diseases that enter the through groove 2 9 then fall into the top of the piston plate 15 in the inner cavity of the cylinder 1 through the through groove 3 10, thereby completing the trapping of the pests and diseases; it should be noted that the width between two adjacent partitions 8 and the width of the corresponding through groove 1 7 can be shortened according to actual conditions, so as to achieve the trapping of smaller pests; wherein, during the rotation of the push plate 6, the inclined plate 35 is abutted against the outer peripheral wall of the shell 4 or the cavity wall of the through groove 2 9 under the elastic force of the spring 3 34, which further reduces the probability of the pests and diseases escaping;

[0034] At the same time, the rotating cylinder 3 drives the threaded sleeve 11 to move downward, and the set threaded sleeve 11 drives the ring body 12, the mounting frame 13, the sliding rod 14 and the piston plate 15 to move downward, so that the gas at the lower part of the piston plate 15 enters into the circulation chamber 18 through the through groove four 20. It should be noted that the circulation chamber 18 is filled with stored water, and the gas enters into the inner cavity of the cylinder 3 through the through groove four 20, the through groove five 21, the through groove six 22 and the through groove seven 23 in turn, and finally the gas is discharged from the inner cavity of the shell 4 through the through groove eight 24 and the through groove nine 25 in turn. In this process, the powdered attractant stored in the storage bin 26 is discharged under the action of gravity. A small amount of powder will fall into the through slot nine 25, and the discharged gas can carry this part of powder to adhere to the top of the cylinder 1, so as to enhance the attraction effect on pests and diseases; in addition, since the gas circulates in the circulation chamber 18, the gas will carry a part of water vapor when it is discharged from the circulation chamber 18, and this part of water vapor will combine with the powdered attractant, making the powdered attractant more easily adhere to the top of the cylinder 1; it should be noted that after the powdered attractant in the through slot nine 25 is discharged, the powdered attractant in the storage bin 26 can replenish the attractant consumed in the through slot nine 25 under the action of gravity;

[0035] At the same time, the piston plate 15 is blocked by the blocking rod 29 when it moves downward. When the two adjacent springs 16 are stretched and contracted to a certain extent, the blocking rod 29 is forced to move toward the inside of the installation groove 27. At this time, the piston plate 15 loses the blockage of the corresponding blocking rod 29 and quickly moves downward for a distance, thereby achieving a pulse effect; thereby, the gas pushed by the piston plate 15 can also achieve a similar pulse effect. The pulsed airflow can more quickly carry the powdered attractant out of the through groove nine 25 to avoid the powdered attractant clogging the through groove nine 25; accordingly, because the piston plate 15 moves downward in a pulsed manner, the external gas will enter the inner cavity of the cylinder 1 through the through groove two 9 and the through groove three 10. In this process, the gas entering the inner cavity of the cylinder 1 will carry pests and diseases into the inner cavity of the cylinder 1, which to a certain extent enhances the trapping effect of this device on pests and diseases.
