Description

Technical Field

[0001] The utility model relates to the field of prevention and control of stored - product pests, in particular to a wall - mounted trapping device for stored - product pests. Background Art

[0002] Pests will be generated during the storage of grains, also known as stored - product pests. These pests are one of the important factors affecting the safety of grain storage. In order to reduce the losses during grain storage, it is necessary to control these pests.

[0003] Traditional pest - killing methods include directly mixing pesticides in grains. This method will introduce the problem of pesticide residues. Therefore, the state has strict limits on the mixing amount of pesticides in grains, which restricts the use of this pest - killing method. Using traps to trap and kill stored - product pests is a harmless pest - killing method and is thus widely used. Traditional traps include surface traps for trapping crawling pests on the surface of grain piles and flying - pest traps for trapping flying pests in the air.

[0004] For most stored - product pests, they all have the habit of climbing up along the wall, such as Rhizopertha dominica, Cryptolestes ferrugineus, Sitophilus zeamais, Sitophilus oryzae, etc. In grain storage places, it is often possible to see a large number of stored - product pests climbing up along the wall. However, in the prior art, there is a lack of a wall - mounted trapping device for stored - product pests that can be used on the wall and utilize the habit of pests climbing up along the wall to trap and kill pests. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a wall - mounted trapping device for stored - product pests that can utilize the habit of pests climbing up along the wall to trap and kill pests.

[0006] To solve the above - mentioned technical problems, the technical solution of a wall - mounted trapping device for stored - product pests in the utility model is as follows:

[0007] A wall - mounted trapping device for stored - product pests includes a device housing that is open on the left side and is used to be buckled on the wall. A pest inlet extending in the front - rear direction is formed between the bottom of the device housing and the wall. A reversing roller, a tape - releasing roller, and a tape - winding roller with a rotation axis extending in the front - rear direction are rotationally assembled in the device housing. A sticky insect tape with an adhesive layer on the outer side is wound around the tape - releasing roller. The sticky insect tape passes around the reversing roller and then is wound around the tape - winding roller. A torque input end is provided on the tape - winding roller. A pest guiding structure is provided between the top of the device housing and the wall for guiding pests crawling along the wall to the sticky insect tape above the reversing roller.

[0008] Further, an attractant and an insecticide are provided on the adhesive layer.

[0009] Further, the torque input end is connected with a crank.

[0010] Further, the torque input end is a transmission inner square hole, and the rocker has a transmission outer square shaft adapted to be plugged and connected with the transmission inner square hole.

[0011] Further, the reversing roller, the unwinding roller and the winding roller are distributed in a triangle, the reversing roller is located at the uppermost side, the unwinding roller is located on the right side of the reversing roller, and a crawling channel for pests to crawl from bottom to top is formed between the left side of the sticky insect tape between the winding roller and the reversing roller and the wall surface.

[0012] Further, the width of the crawling channel in the left-right direction gradually becomes narrower from bottom to top.

[0013] Further, the device housing includes a front side plate, a rear side plate, an upper side plate and a lower side plate arranged between the front side plate and the rear side plate. The lower end of the upper side plate is connected to the upper end of the lower side plate, and a pest inlet is formed between the bottom of the lower side plate and the wall surface. The wall surface, the upper side plate and the lower side plate form a triangular structure.

[0014] Further, the front and rear ends of the reversing roller, the winding roller and the unwinding roller are respectively rotatably assembled on the front side plate and the rear side plate. The unwinding roller is located at the corner position formed by the upper side plate and the lower side plate, and the winding roller is located below the reversing roller and the unwinding roller.

[0015] Further, the upper end of the upper side plate is used for contacting and cooperating with the wall surface. The pest guiding structure includes a guiding plate fixed on the upper side plate and gradually extending obliquely leftward from top to bottom. The bottom of the guiding plate contacts and cooperates with the wall surface.

[0016] The beneficial effects of the present utility model are as follows: When in use, only need to buckle the left side of the device housing on the wall surface above the surface of the grain pile. Utilizing the characteristic that pests crawl upward along the wall surface, the pests will pass through the pest inlet and continue to crawl upward along the wall surface. Finally, they are guided by the pest guiding structure to the sticky insect tape above the reversing roller and are adhered by the sticky insect tape to achieve insecticidal effect. When the pests adhered to the sticky insect tape are saturated, rotate the winding roller, and the winding roller winds up the sticky insect tape adhered with pests, while the new non-adhered sticky insect tape is released by the unwinding roller, so as to carry out new insecticidal work. The sticky insect tape is entirely in the device housing, avoiding the problem of tape failure caused by dust covering.

[0017] Further, the attractant on the sticky insect tape can attract more pests, and the insecticide on the sticky insect tape can achieve rapid killing of pests. Since the insecticide will not diffuse into the environment, pyrethroid insecticides with high toxicity and fast insecticidal speed can be selected to improve the efficiency of adhering and killing pests. Similarly, the attractant and the insecticide are also in the device housing, avoiding the influence of dust on these chemical agents, and can extend the service life of the insecticide and the attractant on the sticky insect tape.

[0018] Furthermore, pests on the sticky tape are collected in a timely manner, avoiding the problem of visual discomfort caused by dense pests. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] An embodiment of a storage pest wall trapping device in the present utility model is as Figures 1 to 3 shown: It includes a device housing 11 with an open left end for buckling on the wall surface. The buckling in this embodiment means that the device housing with a cavity is directly attached to the wall surface. When in use, the upper end of the device housing can be fixed to the wall surface by means of tape or screws or other methods.

[0027] The device housing includes a front side plate 12, a rear side plate 1, an upper side plate 2 and a lower side plate 17 disposed between the front side plate 12 and the rear side plate 1. The lower end of the upper side plate is connected to the upper end of the lower side plate. The wall surface, the upper side plate and the lower side plate form a triangular structure, and a pest inlet 9 extending in the front-rear direction is formed between the bottom of the lower side plate and the wall surface.

[0028] A reversing roller 5, a unwinding roller 3 and a winding roller 7 with a rotation axis extending in the front-rear direction are rotatably assembled in the device housing 11. In this embodiment, both ends of the reversing roller 5, the unwinding roller 3 and the winding roller 7 are rotatably assembled on the front side plate 12 and the rear side plate 1 respectively. An insect-catching tape with an adhesive layer coated on the outer side is wound around the unwinding roller. The specific structure of the insect-catching tape is as Figure 3 described. It includes a base tape 15 on the inner side, an adhesive layer is disposed on the outer side of the base tape 15, and an attractant and an insecticide are mixed in the adhesive layer. The insecticide is a pyrethroid insecticide. The insect-catching tape itself belongs to the prior art.

[0029] The insect-catching tape 6 is wound around the winding roller 7 after passing around the reversing roller 5, and a torque input end is provided on the winding roller 7. In this embodiment, the torque input end is connected to a crank 13. Specifically, the torque input end is a transmission inner square hole, and the crank has a transmission outer square shaft 14 adapted to be inserted and connected to the transmission inner square hole. The crank can be removed from the torque input end. When it is necessary to rotate the winding roller, the transmission outer square shaft of the crank is inserted into the transmission inner square hole of the winding roller, and the winding roller is rotated by the crank. After the rotation is completed, the crank is taken away.

[0030] A pest guiding structure is provided between the top of the device housing and the wall surface for guiding pests crawling along the wall surface to the insect-catching tape on the upper side of the reversing roller. In this embodiment, the reversing roller 5, the unwinding roller 3 and the winding roller 7 are distributed in a triangle. The reversing roller 5 is located at the uppermost side, the unwinding roller 3 is located on the right side of the reversing roller 5, and a crawling channel 10 for pests to crawl from bottom to top is formed between the left side of the insect-catching tape between the winding roller 7 and the reversing roller 5 and the wall surface. The width of the crawling channel in the left-right direction gradually becomes narrower from bottom to top.

[0031] The unwinding roller 3 is located at the corner position formed by the upper side plate 2 and the lower side plate 17. The winding roller is located below the reversing roller and the unwinding roller, and the reversing roller 5 is located at the upper left end of the upper side plate. The upper end of the upper side plate 2 is used for contact and cooperation with the wall surface. The pest guiding structure includes a guiding plate 4 fixed on the upper side plate and gradually extending obliquely to the left from top to bottom. The bottom of the guiding plate is in contact and cooperation with the wall surface.

[0032] During use, the left sides of the upper side plate and the guiding plate are in contact with the wall surface, ensuring the stability of the entire device housing. The upper end of the device housing is connected to the wall surface by tape (or screws), fixing the entire device housing to the wall surface on the upper side of the grain surface. Taking advantage of the habit of pests to climb upward along the wall surface, the pests enter the inner side of the device housing through the pest entrance and continue to climb upward along the wall surface. Eventually, the pests crawl to the upper side of the reversing roller through the guiding plate. Under the attracting effect of the attractant, they fall onto the sticky tape for catching insects on the upper side of the reversing roller, are adsorbed by the adhesive layer, and come into contact with the insecticide and are quickly killed. When the sticky tape for catching insects on the upper side of the reversing roller is saturated with the adhered pests, the staff can rotate the winding roller to wind the sticky tape for catching insects with adhered pests onto the winding roller, while the sticky tape for catching insects without adhered pests is released by the unwinding roller to start a new round of pest trapping work.

[0033] The utility model has the following characteristics: (1) In the non-exposed space formed by the device housing, it avoids the invalidation of the sticky tape for catching insects caused by dust covering, and can effectively extend the service life of the insecticide and the attractant on the sticky tape for catching insects; (2) The pests on the sticky tape for catching insects are collected in time, avoiding visual discomfort and solving the problem of invalidation caused by the tape being full of pests; (3) Since the insecticide will not spread into the environment, pyrethroid insecticides with high toxicity and fast insecticidal speed can be selected to improve the efficiency of adhering pests.
