[0002] In the agricultural greenhouse environment, effective control of pests is one of the key factors to ensure the healthy growth of crops and improve yield. The closed or semi-closed environment in the greenhouse provides favorable conditions for the breeding of pests, and also increases the difficulty of pest management. Although the traditional chemical pesticide method can control pests to some extent, long-term use not only pollutes the environment, but also may destroy the ecological balance and affect the quality and safety of agricultural products. Therefore, developing efficient and environmentally friendly pest trapping devices has become an important direction for pest management in agricultural greenhouses.

[0003] In the agricultural greenhouse environment, there are many types of pests with different behavior habits, and some pests may not be sensitive to the light source, color plate or chemical substances in the trapper, or they may be difficult to attract due to their high vigilance. In addition, the existing device generally adopts a passive capture mechanism, that is, even if the pests are successfully attracted to the vicinity of the trapper, they also need to enter the device themselves, which increases the risk of escape, especially for small and flexible pests, resulting in low trapping efficiency.

[0004] Therefore, we propose a pest trapping device for agricultural greenhouse to solve the above problems. INVENTION CONTENTS

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0031] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the drawings in the description and specific embodiments.

[0032] Reference Figures 1-2 A kind of pest trapping device for agricultural greenhouse, including installation shell 1, collecting cylinder 2 and four trapping cylinders 3.

[0033] The top of the installation shell 1 is provided with four equidistantly distributed installation pipes 11, and the installation pipes 11 are threadedly connected with containing pipes 13 for placing trapping agents. The trapping agents can be placed or replaced by rotating the containing pipes 13. Different types of trapping agents can be placed in each trapping cylinder 3, so that different types of pests in the greenhouse can be trapped, and the adaptability and practicality of the device are improved. The side wall of the trapping cylinder 3 is provided with a plurality of evenly distributed odor holes 32. The odor emitted by the trapping agent escapes outward through the odor holes 32, attracts pests, and the two opposite sides of the installation shell 1 are open to form an open port 14 for pests to enter. The pests approach the trapping cylinder 3 through the open port 14, and the trapping of the pests is realized.

[0034] Referring to Figure 3 The collection cylinder 2 is detachably installed on the connecting pipe 12 arranged at the bottom of the installation shell 1, and is used for collecting trapped pests. The inner side wall of the connecting pipe 12 is provided with a plurality of L-shaped clamping grooves 121, and the opening of the collection cylinder 2 is provided with clamping columns 21 matched with the clamping grooves 121. When the collection cylinder 2 is installed, the clamping columns 21 are aligned with the clamping grooves 121, and then the clamping columns 21 are clamped into the clamping grooves 121, and the collection cylinder 2 is rotated to realize the connection between the collection cylinder 2 and the connecting pipe 12, which facilitates the cleaning of the collection cylinder 2.

[0035] Referring to Figures 2-3 The inner side of the input end of the collection cylinder 2 is provided with a plurality of elastic blocking strips 22. The elastic blocking strips 22 are bent towards the bottom of the collection cylinder 2 to form a large upper and small lower conical structure. When the pests fall from the installation shell 1 into the collection cylinder 2, the elastic blocking strips 22 are bent under the action of gravity and recover after the pests enter the collection cylinder 2. The elastic blocking strips 22 effectively reduce the risk of escape of the pests by shielding the opening of the collection cylinder 2.

[0036] The trapping cylinder 3 is located in the installation shell 1 and is rotationally connected with the installation pipe 11. The top of the trapping cylinder 3 is provided with a mounting hole, and the mounting hole is rotationally connected with the installation pipe 11. The containing pipe 13 extends into the trapping cylinder 3. A transmission structure is arranged between a plurality of trapping cylinders 3 to simultaneously rotate the trapping cylinders 3 and reversely rotate the trapping cylinders 3 at adjacent positions. The two trapping cylinders 3 located at the open port 14 are driven by the transmission structure to roll towards the inside of the installation shell 1. Through the design of the trapping cylinder 3 rolling towards the inside of the installation shell 1, active capture of pests is realized, and the limitation of the traditional trapping device relying on the active entry of pests is overcome.

[0037] Referring to Figures 4-5The transmission structure comprises a motor 4 fixedly installed above the mounting shell 1, the output end of the motor 4 extends into the mounting shell 1 and is fixedly installed with a driving gear 41, the outer wall of the trapping cylinder 3 is fixedly sleeved with toothed rings 34, four toothed rings 34 are meshed with each other, the driving gear 41 is meshed with one of the toothed rings 34, the driving gear 41 is controlled to rotate by the motor 4, thereby driving one of the toothed rings 34 to rotate, so that the plurality of toothed rings 34 rotate synchronously, since the toothed rings 34 are meshed with each other, the rotation directions of the adjacent toothed rings 34 are opposite, the opposite rotation is realized, thereby controlling the trapping cylinder 3 to roll.

[0038] With reference to Figures 4-6 The trapping cylinder 3 is provided with a plurality of bristles 31 equidistantly distributed on the side surface, when the pests adhere to the trapping cylinder 3, the pests are limited to escape by the bristles 31, and the pests are quickly taken action, so that the trapping efficiency and success rate are effectively improved, the bristles 31 on two adjacent trapping cylinders 3 are staggered up and down, and the bristles 31 extend into the interval region between the two groups of longitudinally arranged bristles 31 on the adjacent trapping cylinder 3, when the trapping cylinder 3 rolls, the pests are transported to the inside of the mounting shell 1 in the process that the bristles 31 rotate to the inside of the mounting shell 1, and active trapping is realized.

[0039] With reference to Figures 4-7 The mounting shell 1 is provided with a plurality of longitudinally distributed scraping rods on the scraping plate 15 fixedly installed on the two side walls, the scraping rods are close to the side wall of the trapping cylinder 3, when the pests enter the mounting shell 1, in order to prevent the pests from escaping with the bristles 31, the bristles 31 are scraped by the scraping rods on the scraping plate 15, so that the pests trapped in the bristles 31 are combed off by the scraping rods, thereby falling into the collecting cylinder 2.

[0040] The inner wall of the trapping cylinder 3 is provided with a plurality of baffles 33 arranged in the axial direction, and the cross section of the baffle 33 has an angle with the diameter direction of the trapping cylinder 3, when the trapping cylinder 3 rotates, the baffle 33 can promote the flow of air flow, so that the smell of the trapping agent is emitted more widely, not only the utilization efficiency of the trapping agent is improved, but also the trapping range is expanded, the opportunity of the pests being attracted and captured is increased, and the trapping effect is improved.

[0041] Working principle:

[0042] In use, the trapping device is hung in a suitable position in a greenhouse. When the greenhouse is large, multiple trapping devices can be arranged at intervals. After the containing tube 13 is rotated out, the trapping agent is placed in the containing tube 13. The motor 4 is started, and the motor 4 controls the rotation of the driving gear 41, which in turn drives the rotation of one of the toothed rings 34, so that the multiple toothed rings 34 rotate synchronously, thereby controlling the trapping cylinder 3 to roll against the roller, the trapping agent emits an odor, which escapes outward through the odor holes 32, attracting pests to approach. When the pests adhere to the trapping cylinder 3, the brush 31 restricts the pests from escaping. The pests are transported to the installation shell 1 during the rotation of the brush 31 and the installation shell 1, thereby achieving active capture. The pests trapped in the brush 31 are scraped off by the scraper rods on the scraper 15, and then fall into the collecting cylinder 2.

[0043] When the pests fall from the installation shell 1 into the collecting cylinder 2, the elastic blocking strip 22 is bent under the action of gravity, and then restores after the pests enter the collecting cylinder 2. The elastic blocking strip 22 effectively reduces the risk of pest escape by blocking the opening of the collecting cylinder 2.

[0044] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes within the technical range disclosed by the present application according to the technical scheme and the inventive concept of the present application, which should be covered within the protection scope of the present application.
