Description

Technical Field

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

[0002] During the tree planting process, pests will climb up the trees along the trunks. Most of these pests cause serious damage to the plants. Their living habits are generally to come out at night, hide in the soil during the day, lay eggs at the base of the tree trunks and in the weeds, and after hatching, they climb up through the tree trunks and eat the leaves, which has a great impact on the normal growth of the trees.

[0003] In order to solve the problem that "the existing solution uses the calculation of the predetermined time to decompose the insect repellent bag, which is prone to calculation errors", the Chinese patent with the publication number CN207836582U discloses a tree pest control device, including a ring-shaped member sleeved on the tree, the inner surface of the ring-shaped member is provided with a receiving groove for spraying insecticide, and the lower surface of the ring-shaped member is provided with an insect inlet hole connected to the receiving groove. Although the existing technical problems have been solved, the following problems still exist:

[0004] However, in this technical solution, the medicine needs to be applied manually into the containing groove. Manual application of the medicine is difficult to apply evenly and comprehensively, and is quite inconvenient. Therefore, corresponding improvements are made to address this problem. Summary of the invention

[0005] Based on the technical problems existing in the prior art, the present invention proposes a biological control device for tree pests.

[0006] A biological control device for tree pests proposed by the present invention comprises two half boxes that can be embraced on a tree, wherein a drug coating chamber is arranged in the half box, wherein an inlet is opened on the bottom wall of the drug coating chamber, and both side edges of the inlet are provided with upwardly protruding anti-overflow warping edges, wherein a lower partition and an upper partition that can move up and down are arranged in the drug coating chamber, wherein the upper partition is located above the lower partition, and a plurality of springs are fixed to the bottom of the lower partition, and the other end of the spring is fixed to the bottom wall of the drug coating chamber, and the upper partition is connected to a pressing component, and the pressing component is used to press the upper partition downward, and before the half box is fixed to the tree, the insecticide paste is first placed between the upper partition and the lower partition, and then the upper partition is pressed downward by the pressing component, and the upper partition first squeezes the insecticide paste onto the lower partition and fills the upper partition with the insecticide paste The upper partition and the lower partition will move downward together, and the insecticide cream between the upper partition and the lower partition will be smeared on the inner walls on both sides of the coating chamber. After the downward pressure component is released, the lower partition and the upper partition will be pushed to reset under the action of the spring, so that the part of the coating chamber where the insecticide cream is smeared will be exposed. Finally, the two half boxes will be hugged and fixed on the tree. The pests will crawl along the tree and enter the coating chamber through the entrance. The pests will be killed after eating the insecticide cream. When the insecticide cream on the inner wall of the coating chamber is dry, since the insecticide cream between the upper partition and the lower partition has good sealing performance and will not dry quickly, the upper partition and the lower partition can be pressed down again by the downward pressure component to repeat the application of the insecticide cream.

[0007] Preferably, a feed pipe is provided on the circumferential outer wall of the half box, and the feed pipe is located above the lower partition. The end of the feed pipe is threadedly connected with a pipe cover. The upper partition is lifted upward by a downward pressing assembly so that the upper partition is located above the feed pipe, and then the insecticide paste can be squeezed into between the lower partition and the upper partition through the feed pipe, so that the insecticide paste can be added to the inside of the half box without removing it from the tree.

[0008] Preferably, a plurality of arched spring pieces distributed in a circular array are provided on the top of the lower partition, and each spring piece is equipped with a pair of frames. The frames are fixed on the top of the lower partition, and the two ends of the spring pieces are respectively inserted into the frames. Under normal circumstances, the spring pieces are in an arched state, which will lift up the upper partition, so that the upper partition will be above the feed pipe, which makes it convenient to add insecticide cream from the feed pipe, and when the upper partition moves downward, the spring pieces will be flattened, so that the insecticide cream between the upper partition and the lower partition can still be squeezed.

[0009] Preferably, the pressing assembly includes a pressing plate and a pair of pressing rods, the pressing rods are fixed at the bottom of the pressing plate, the bottom of the pressing rods passes through the half box and is fixedly connected to the upper partition, and the pressing rods are pressed down through the pressing plate, and the upper partition is pressed down by the pressing rods.

The fixed block is fixed on the top wall of the coating chamber, the axle passes through the fixed block and is rotatably connected to the fixed block, the cam fixing sleeve is arranged on the inner end of the axle, the fan blades are fixed on the outer end of the axle, and a pulley is provided on the fixed sleeve on the axle. The two pulleys are connected by a belt. When the wind blows, the wind will drive the fan blades to rotate, and the fan blades will synchronously drive the axle and the cam to rotate, and the cam will hit the upper partition and then press the upper partition downward. Through the cooperation of the belt and the pulley, the two axles and the cam can keep rotating synchronously.

[0012] Preferably, ears are provided at both ends of the half box, one pair of ears are rotatably connected by a connecting piece, and the other pair of ears are provided with at least one circular hole, and a bolt assembly for fixing the two ears together is inserted between the two circular holes in the same group, so that the two half boxes can be opened at one end, and the opened part can be put on the tree, and then the end that can be opened can be fixed by the bolt assembly.

[0013] Preferably, ears are provided at both ends of the half box, and at least one circular hole is provided on each of the two pairs of ears. A bolt assembly for fixing the two ears together is inserted between the two circular holes in the same group, so that the two half boxes can be combined on the tree at the same time, and then the two ends of the half box can be fixed separately by the bolt assembly.

[0014] Preferably, a convex strip and a groove are respectively provided on one side where the two half boxes meet, and the convex strip can just be inserted into the groove. When the two half boxes are put together, the convex strip will be inserted into the groove, thereby enhancing the sealing and strength of the connection between the two half boxes.
