Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary tools for breeding beneficial bugs, and in particular relates to a negative pressure collection device for breeding beneficial bugs. Background Art

[0002] Beneficial bugs are a predatory group in the Pentatomidae family, especially preying on Lepidoptera larvae, and are natural enemies of pests. There are also species that feed on plants, or need to absorb plant nutrients at a certain stage of individual development, so they are also called semi-beneficial bugs. Because their beaks are thick and straight, they are called large-beaked bugs.

[0003] During the artificial breeding of beneficial bugs, it is usually carried out in breeding cages. However, when beneficial bugs are bred in breeding cages, insect feces are easily accumulated in the breeding cages, which need to be cleaned regularly. In addition, the beneficial bug eggs need to be selected from the beneficial bug breeding cages during the egg-laying period. The existing work is basically done manually, which is time-consuming, labor-intensive and inefficient.

[0004] Based on this, a negative pressure collection device for breeding beneficial bugs is proposed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a negative pressure collection device for breeding beneficial bugs, comprising a collection cylinder 1, a collection head 2 and a negative pressure machine 3;

[0025] A top connecting port 11 is provided at the top of the collecting tube 1, and the collecting head 2 is connected to the top connecting port 11 through a connecting pipe 22. The collecting head 2 is specifically a hard tube with an oblique opening at the working end, and an anti-slip tube 21 is pasted and fixed to the outer side of the middle section of the collecting head 2. When in use, the oblique opening of the collecting head 2 is extended into the bottom of the beneficial stink bug breeding cage. The negative pressure generated by the negative pressure machine 3 can suck the insect feces or insect eggs in the breeding cage into the collecting head 2, and send them into the collecting tube 1 under the action of the connecting pipe 22.

[0026] A first filter screen 12 and a second filter screen 13 are fixed in the collecting tube 1 at an angle from top to bottom. The first filter screen 12 and the second filter screen 13 divide the inner cavity of the collecting tube 1 into three collecting spaces, so that the collected insect feces or insect eggs can be divided into the three collecting spaces and stored separately under the action of the first filter screen 12 and the second filter screen 13.

[0027] A bottom connection port 14 is provided at the same side of the bottom end of the collecting cylinder 1 and the higher end of the first filter screen 12. A third filter screen 15 is fixed inside the collecting cylinder 1 near the bottom connection port 14. The working end of the negative pressure machine 3 is connected to the bottom connection port 14 through a connecting pipe. The negative pressure generated by the negative pressure machine 3 can be transmitted to the oblique opening of the collecting head 2 through the collecting cylinder 1 through the bottom connection port 14.

[0028] Under the action of the third filter screen 15 , impurities on the bottom surface can be prevented from entering the negative pressure machine 3 , thereby increasing the service life of the negative pressure machine 3 .

[0029] In order to facilitate the placement of the insect excrement or insect eggs collected by the collecting head 2 in space by level, the mesh sizes of the first filter 12, the second filter 13 and the third filter 15 are reduced in sequence.

[0030] A first opening and closing door 16 is provided on the side of the collecting cylinder 1 near the lower end of the first filter screen 12, and the collection or cleaning of the materials on the first filter screen 12 can be completed by opening the first opening and closing door 16. A second opening and closing door 17 is provided on the side of the collecting cylinder 1 near the lower end of the second filter screen 13, and the collection or cleaning of the materials on the first filter screen 13 can be completed by opening the second opening and closing door 17. A bottom cleaning port 18 is provided in the middle of the bottom surface of the collecting cylinder 1, and the collection or cleaning of the materials at the bottom of the collecting cylinder 1 can be completed through the bottom cleaning port 18.

[0031] In order to improve the stability of the entire device during use, a base frame 19 is fixed to the bottom of the collecting cylinder 1 , and the negative pressure machine 3 is also fixedly mounted on the base frame 19 .

[0032] In summary, when in use, first move the entire device to the side of the beneficial bug breeding cage that needs to be collected and cleaned, then start the negative pressure machine 3, and the negative pressure generated by the negative pressure machine 3 can be transmitted to the oblique mouth of the collecting head 2 through the bottom connecting port 14 of the collecting tube 1 through the collecting tube 1;

[0033] Then the oblique mouth of the collecting head 2 is extended into the beneficial bug breeding cage near the bottom, and the insect excrement or eggs in the breeding cage can be sucked into the collecting head 2 under the action of negative pressure, and sent into the collecting tube 1 under the action of the connecting pipe 22;

[0034] The insect excrement or eggs entering the collection tube 1 are first filtered by the first filter 12, the second filter 13 and the third filter 15 in sequence, and the collected insect excrement or eggs can be divided into three collection spaces for storage respectively;

[0035] After the collection is completed, the collection or cleaning of the materials on the first filter screen 12 can be completed by opening the first opening and closing door 16, the collection or cleaning of the materials on the first filter screen 13 can be completed by opening the second opening and closing door 17, and the collection or cleaning of the materials at the bottom of the collecting tube 1 can be completed through the bottom cleaning port 18.
