Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, in particular to a grain storage pest trapping and monitoring device. Background Art

[0002] Stored grain pests are one of the common hazards in the storage of rice, wheat, corn and other grains. Their infection and reproduction will cause grain piles to suffer varying degrees of losses. Following the principle of "prevention first, comprehensive control" in stored grain pest control, stored grain pest control is often a comprehensive application of multiple control technologies, and the use of pest traps is a common monitoring method for grain pile pest density. Monitoring of pest population density is conducive to judging the insect situation in grain piles, and is an important basis for the selection of subsequent control measures and methods.

[0003] There are many different designs of stored grain pest trapping and monitoring devices in the prior art, including devices for trapping and monitoring pests on the surface and surface of grain piles: for example, Chinese patent application with publication number CN205624024U discloses a surface layer pest trapping and monitoring device for grain piles, and Chinese patent application with publication number CN113229262A discloses a trap for grain surface; devices for trapping and monitoring pests inside grain piles: for example, Chinese patent application with publication number CN107593652A discloses a pest monitoring system, and Chinese patent application with publication number CN110074080A discloses a pest trap for inside grain piles; devices for trapping pests inside grain piles and on the grain surface: for example, Chinese patent application with publication number CN219894397U discloses a composite stored grain pest trap.

In addition, since the length of the existing trapping device is fixed, it is not flexible enough to use. At the same time, since the length of the existing trapping device is mostly 0.5 meters, 1 meter or more than 1 meter, it is not convenient to carry. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model aims to provide a stored-grain pest trapping and monitoring device to solve the problems existing in the above-mentioned prior art, which is easy to carry and the overall use length can be flexibly adjusted to facilitate trapping and distinguishing pests at different depths in grain piles.

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 1-7 As shown, the utility model provides a stored-grain pest trapping and monitoring device, comprising at least two insect trap tubes 2 and at least two insect collectors 4, the number of the insect trap tubes 2 is equal to the number of the insect collectors 4, the interior of the insect trap tube 2 is provided with an insect falling channel, a plurality of insect trap holes 21 are provided on the side wall of the insect trap tube 2, the insect trap holes 21 are connected with the insect falling channel, the insect trap tubes 2 are connected in sequence from top to bottom, the connection between any two adjacent insect trap tubes 2 is a detachable fixed connection, the insect collectors 4 are arranged at the bottom of the insect falling channel, the interior of the insect collector 4 is provided with an insect collecting space, the top end of the insect collecting space is opened for receiving the stored-grain pests falling from the insect falling channel.

[0032] The utility model provides a storage pest trapping and monitoring device, wherein the insect trap holes 21 are evenly distributed on the side wall of the insect trap tube 2, and are used to lure the pests to crawl into the insect trap tube 2, each insect collector 4 is arranged at the bottom of each insect falling channel, and the interior of the insect collector 4 has an insect collecting space, and the top of the insect collecting space is opened to receive the storage pests falling from the insect falling channel, and the insect collector 4 collects the pests and prevents the pests from escaping, and each insect trap tube 2 is connected in sequence from top to bottom, and the connection between any two adjacent insect trap tubes 2 is a fixed connection that can be detached, which can not only be assembled and disassembled, but also convenient to use, carry and transport, and can be used according to actual storage pest trapping and monitoring needs. The number of connected insect attracting tubes 2 is selected, and the overall length of the connected device is slightly larger than the expected grain pile depth. The overall length of the device can be flexibly adjusted for ease of use. At the same time, each insect collector 4 is arranged at the bottom of each insect falling channel to facilitate the capture and differentiation of pests at different depths of the grain pile, thereby obtaining information such as the type and quantity of pests, and judging the depth of the grain pile where the pests are active, so as to provide effective support for accurately analyzing the influence and law of geographical location, season, warehouse temperature and other conditions on pest migration and distribution depth; as an optional implementation method of this embodiment, the utility model provides a stored grain pest trapping and monitoring device that can be used with a single section of an insect attracting tube 2.

[0033] Furthermore, the outer wall of the insect collector 4 fits closely with the inner wall of the insect collecting space. After the pests crawl into the insect attracting tube 2 through the insect attracting hole 21, they slide down to the bottom insect collector 4 due to the smooth inner wall of the insect attracting tube 2. The outer wall of the insect collector 4 fits closely with the inner wall of the insect collecting space, so that after the pests enter the insect attracting tube 2, they can only fall into the insect collector 4, reducing the possibility of pest escape.

[0034] As a more preferred implementation of this embodiment, the connection between any two adjacent insect attracting tubes 2 is a threaded connection, which has a simple structure and is easy to assemble and disassemble.

[0035] Furthermore, a top cover 1 is fixedly provided at the top of the uppermost insect attracting tube 2 among the insect attracting tubes 2, and the top cover 1 can block the top opening of the uppermost insect attracting tube 2 among the insect attracting tubes 2 to prevent foreign objects from falling into the insect collector 4.

[0036] As a more preferred implementation of this embodiment, the bottom end of the top cover 1 is threadedly connected to the top end of the uppermost insect attracting tube 2 among the insect attracting tubes 2, which has a simple structure and is easy to assemble and disassemble.

[0037] As a more preferred implementation of this embodiment, the threads on the insect-attracting tube 2 and the top cover 1 are both arc-shaped, which is not easy to be damaged, has a high load strength, and is easy to clean.

[0038] Furthermore, the top cover 1 is provided with a hand-held portion, which is convenient for hand-held operations such as plugging and unplugging during use; a rope threading hole is provided at the top of the top cover 1, through which a rope can be passed, for easy management.

[0039] Furthermore, a cone head 3 is fixedly provided at the bottom end of the lowest insect attractant tube 2 in each insect attractant tube 2, and the cone head 3 is utilized to reduce the resistance when the insect attractant tube 2 is inserted into the grain pile, so that it can save effort when used in the grain pile; as a more preferred implementation manner of this embodiment, the cone head 3 is integrally formed with the lowest insect attractant tube 2 in each insect attractant tube 2; as another more preferred implementation manner of this embodiment, the cone head 3 is threadedly connected to the lowest insect attractant tube 2 in each insect attractant tube 2.

[0040] As a more preferred implementation of this embodiment, the upper and middle part of the cone head 3 is a frustum part, and the lower part of the cone head 3 is a hemispherical part. The frustum part gradually shrinks inward from top to bottom to the hemispherical part. The relatively rounded design of the cone head 3 facilitates the insertion and removal of grain in the grain pile while avoiding injuries from the sharp tip.

[0041] Furthermore, the top of the insect collector 4 has a guide portion, and the bottom of the guide portion is provided with a slide-in hole 41. The side wall of the guide portion gradually shrinks from the top of the guide portion to the slide-in hole 41 to the slide-in hole 41. The smooth inward-contracted guide portion plays a role in regulating the movement direction of the pests, so that the pests falling into the insect attracting tube 2 can continue to slide down and enter the collection cavity 42 from the slide-in hole 41, and finally complete the collection of the pests. At the same time, the guide portion and the slide-in hole 41 are also channels for pouring out the pests. The bottom of the insect collector 4 has a collection cavity 42, and the collection cavity 42 and The sliding hole 41 is connected, and a transparent bottom cover 43 is fixedly provided at the bottom end of the collecting chamber 42. The number of pests in the collecting chamber 42 and the trapping effect can be directly observed through the transparent bottom cover 43. When taking out the captured pests, it can also be observed whether there are still pests in the collecting chamber 42 to avoid a small amount of pests remaining inside the insect collector 4, so as not to affect the statistical results of the number of trapped pests. As a more preferred implementation method of this embodiment, the transparent bottom cover 43 is made of a transparent plastic sheet, and the transparent bottom cover 43 is pasted on the bottom end of the collecting chamber 42.

[0042] Furthermore, there are two sliding holes 41, which are the first sliding hole and the second sliding hole respectively. The opening of the first sliding hole is larger than the opening of the second sliding hole. Through the design of a large and a small double hole, it is convenient to pour out the pests while completing the pest collection function; the collecting chamber 42 is a truncated cone collecting chamber, and the side wall of the collecting chamber 42 gradually shrinks inward from the top of the collecting chamber 42 to the bottom of the collecting chamber 42. The truncated cone busbar has a certain angle with the bottom surface, preferably but not limited to 76°. The larger slope makes it difficult for pests to escape, forming a space for collecting pests.

[0043] The grain storage pest trapping and monitoring device provided by the utility model can be combined by combining different numbers of insect trap tubes 2, and each section of the insect trap tube 2 can independently trap and collect pests. The insect trap tubes 2 can also be arbitrarily combined to achieve different lengths, and the trapping depth can be flexibly changed, so as to facilitate flexible adjustment during actual use to meet various needs, and it has a certain degree of portability, and only needs to carry an appropriate number of components during transportation, and then combine and install them when they are used.

[0044] The grain-stored pest trapping and monitoring device provided by the utility model, when in use: a suitable number of insect trap tubes 2 are selected according to needs, and the grain-stored pest trapping and monitoring device provided by the utility model is inserted into a grain pile after assembly, and abnormal grain conditions such as high grain temperature and high moisture content can be selected for arrangement, and the pests in the grain pile crawl into the insect trap holes 21 on the side walls of the insect trap tubes 2, and slide down from the smooth inner wall of the insect-falling channel to the insect collector 4 at the bottom of the insect trap tubes 2. After entering the insect-falling channel, it is difficult for the pests to crawl out and escape. After being arranged for a period of time, the grain-stored pest trapping and monitoring device provided by the utility model is taken out and disassembled, the insect collector 4 in each section of the insect trap tube 2 is taken out, the pests in the insect collector 4 are poured out, and the types and quantities of the trapped pests are checked.

[0045] The trapping principle of the stored-grain pest trapping and monitoring device provided by the utility model is as follows: first, a substance capable of attracting pests, such as crushed grains, powdered grain oil or insect pheromones, is placed at the bottom of each section of the insect trapping tube 2. The relatively strong odor emitted by these substances can attract the pests to move toward the insect trapping tube 2; thereafter, the stored-grain pest trapping and monitoring device provided by the utility model can be inserted into the grain pile to a certain depth as required. Since it is provided with a cone head 3, insertion is more labor-saving; on the surface of the grain pile, some pests will crawl into the insect trapping tube 2 along the outer wall of the insect trapping tube 2 due to their climbing nature, and inside the grain pile, pests with the habit of drilling holes will also enter the insect trapping tube 2 through the insect trapping hole 21.

[0046] As an optional implementation of this embodiment, the insect attractant tube 2 can be made by, but not limited to, a mold or 3D printing method. The inner wall surface is smooth enough to make it difficult for pests to return once they enter. The insect collector 4 is wide at the top and narrow at the bottom. It can regulate the position where the pests fall and effectively prevent the pests from escaping. The insect collector 4 is placed in each section of the insect attractant tube 2. Each section of the insect attractant tube 2 is provided with a 1 cm base to isolate the two adjacent insect attractant tubes 2. This structure in which multiple sections of insect attractant tubes 2 collect pests separately can monitor the vertical distribution of stored grain pests and the migration patterns that occur over time and in seasons.

[0047] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
