Description

Technical Field

[0001] This utility model belongs to the field of grain storage technology, and in particular relates to a controlled atmosphere storage insect-proof line replenishment device. Background Technology

[0002] Controlled atmosphere storage (CAS) technology is widely used in grain storage to inhibit the growth and reproduction of pests by regulating the composition of ambient gases. Pest control lines in CAS storage systems are an important measure to solve specific problems encountered in CAS storage systems.

[0003] Currently, controlled atmosphere storage technology is widely implemented across the country, but some technical challenges remain. In shallow circular silos, the repeated infestation of stored grain pests at the silo entrance is a common problem. The root causes are several: 1. Insufficient duration of nitrogen concentration in certain areas, resulting in pests not being killed. 2. Larvae or egg-stage stored grain pests are difficult to kill with nitrogen; as the nitrogen concentration decreases, they mature into adults, leading to repeated infestations at the silo entrance. 3. External pests enter the silo entrance through gaps in the film and pressure groove. To address these issues, it is essential to install insect-proof lines in the controlled atmosphere storage during the sealing phase. This can compensate for insufficient duration of nitrogen concentration in certain areas, attract and kill larvae and other pests, and cut off cross-infection routes from external pests.

[0004] Currently, insecticides commonly used in insect control lines are divided into solid and liquid forms. Solid insect control lines, such as inert powder, are less effective at killing Coleoptera pests. Liquid insecticides, such as methyl pyrimidine phosphate, are more effective at killing a wider range of pests. However, insect control lines in controlled atmosphere chambers are generally placed inside a membrane. When adding the insecticide, personnel need to obtain approval according to the requirements for confined space operations, wear positive pressure breathing apparatus, open the membrane, and add the insecticide. This operation carries the risk of personnel hypoxia and suffocation. At the same time, the operation process involves many steps, is time-consuming, and has high labor costs.

[0005] To address these issues, we provide a controlled atmosphere chamber insect repellent refill device. Utility Model Content

[0006] The purpose of this invention is to provide a controlled atmosphere chamber insect-proof line replenishment device. By combining the replenishment component and the insect-proof hose, it solves the problems in the prior art where the controlled atmosphere chamber insect-proof line is generally placed inside the film, and the addition of the medicine requires personnel to obtain approval according to the confined space operation requirements, which can easily lead to the risk of oxygen deficiency and suffocation, as well as the repeated breeding of pests at the chamber door.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a controlled atmosphere chamber insect-proof line refill device, comprising an insect-proof shell, a sponge board at the bottom of the inner cavity of the insect-proof shell, an insect-proof flexible tube at the top of the sponge board, a perforation on the surface of the insect-proof flexible tube, a refilling component at one end of the insect-proof flexible tube, the refilling component including a fastening screw, one end of the fastening screw being fixedly connected to one end of the insect-proof flexible tube, a connecting gasket at the end of the fastening screw away from the insect-proof flexible tube, a membrane connector on one side of the connecting gasket, a sealing valve at one end of the membrane connector, and an injection tube at one end of the sealing valve.

[0009] The present invention is further configured such that a threaded tube is fixedly connected to one side of the connecting pad, and the threaded tube is threadedly connected to the fastening screw. The threaded tube is rotated to rotate within the cavity of the fastening screw, and the external thread on its surface meshes with the internal thread on the inner wall of the fastening screw, so that the fastening screw installs and fixes the threaded tube within the cavity of the insect-proof hose, thereby improving the connection stability between the membrane connector and the insect-proof hose.

[0010] The present invention is further configured such that a plug is fixedly connected to one end of the threaded tube, and a sleeve is snapped onto the surface of the plug. The outer surface of the sleeve is fixedly connected to the inner wall of the insect-proof hose. As the membrane connector is connected to the insect-proof hose, the threaded tube penetrates the inner cavity of the sleeve. The sleeve can improve the sealing performance of the connection between the membrane connector and the insect-proof hose and prevent liquid backflow.

[0011] The present invention is further configured such that a fixing rod is fixedly connected to one side of the inner cavity of the insect-proof shell, and a fixing sleeve is fixedly connected to one end of the fixing rod. The inner cavity of the fixing sleeve is movably connected to the surface of the insect-proof hose. Several sets of fixing sleeves are wrapped around the surface of the insect-proof hose, thereby fixing the insect-proof hose in the inner cavity of the insect-proof shell, preventing it from being scattered in the inner cavity of the insect-proof shell, and allowing the insect-proof liquid flowing out from the perforated surface to flow evenly onto the sponge board.

[0012] The present invention is further configured such that a limiting sleeve is fixedly connected to one side of the inner cavity of the insect-proof shell, the inner cavity of the limiting sleeve is movably connected to the surface of the insect-proof hose, and the limiting sleeve on the side of the insect-proof shell limits and fixes the insect-proof hose, so that it is kept in a fixed position inside the insect-proof shell, and the insect-proof liquid flowing down from the medicine replenishment component can quickly flow into the insect-proof hose.

[0013] The present invention is further provided with a sealing ring on one side of the fastening screw, and the side of the sealing ring away from the fastening screw contacts the surface of the connecting pad. The sealing ring can improve the sealing between the fastening screw and the connecting pad, thereby improving the connection sealing between the membrane connector and the insect-proof hose.

[0014] The present invention is further configured such that a sealing plug is provided on one side of the injection tube, and a pull ring is fixedly connected to one side of the sealing plug. Inserting the sealing plug into the inner cavity of the injection tube can prevent external dust and impurities from entering the injection tube and causing blockage. The insect repellent can be injected into the replenishment component by removing the sealing plug.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model places the insect-proof hose inside the insect-proof shell and connects it to the refilling component. The membrane connector passes through the insect-proof membrane, allowing workers to operate directly without entering the insect-proof membrane to disassemble the entire device. The process of removing the sealing plug and injecting the medicine through the injection tube with a syringe is simple and easy to learn. The sealed valve design can prevent medicine leakage and ensure that the refilling process is safe and efficient. This "plug and play" design reduces cumbersome steps and greatly improves the work efficiency of refilling insect-proof medicine in grain warehouses.

[0017] 2. In this utility model, after the agent enters the insect-proof hose through the injection tube and the membrane connector, it can evenly penetrate to the surface of the sponge board through the holes on the surface of the hose, forming a continuous and uniform insect-proof line. This design avoids the problem of local accumulation or uneven distribution of the agent, so that the insect-proof line can fully cover the storage area, effectively enhancing the stability and continuity of the insect-proof effect.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0025] Please see Figure 1-4 This utility model is a controlled atmosphere chamber insect-proof line refill device, including an insect-proof shell 1, a sponge board 2 at the bottom of the inner cavity of the insect-proof shell 1, an insect-proof hose 3 at the top of the sponge board 2, a hole 4 on the surface of the insect-proof hose 3, a refill component 5 at one end of the insect-proof hose 3, the refill component 5 including a fastening screw 501, one end of the fastening screw 501 being fixedly connected to one end of the insect-proof hose 3, a connecting pad 502 at the end of the fastening screw 501 away from the insect-proof hose 3, a membrane connector 503 on one side of the connecting pad 502, a sealing valve 504 at one end of the membrane connector 503, and an injection tube 505 at one end of the sealing valve 504.

[0026] Specifically: Draw an appropriate amount of insect repellent into the syringe, open the sealed valve 504, insert the syringe tip into the inner cavity of the injection tube 505, and push the repellent into the inner cavity of the injection tube 505 through the syringe. The repellent enters the insect repellent hose 3 through the membrane connector 503, and finally flows through the perforated 4 on the surface of the insect repellent hose 3 to the surface of the sponge board 2 to form an insect repellent line. Example 2

[0027] Please see Figure 1-4 Based on Embodiment 1, a threaded tube is fixedly connected to one side of the connecting pad 502. The threaded tube is threadedly connected to the fastening screw 501. A plug is fixedly connected to one end of the threaded tube. A cover is snapped onto the surface of the plug. The outer surface of the cover is fixedly connected to the inner wall of the insect-proof hose 3. A fixing rod is fixedly connected to one side of the inner cavity of the insect-proof shell 1. A fixing sleeve 6 is fixedly connected to one end of the fixing rod. The inner cavity of the fixing sleeve 6 is movably connected to the surface of the insect-proof hose 3. A limiting sleeve is fixedly connected to one side of the inner cavity of the insect-proof shell 1. The inner cavity of the limiting sleeve is movably connected to the surface of the insect-proof hose 3. A sealing ring 7 is provided on one side of the fastening screw 501. The side of the sealing ring 7 away from the fastening screw 501 contacts the surface of the connecting pad 502. A sealing plug is provided on one side of the injection tube 505. A pull ring is fixedly connected to one side of the sealing plug.

[0028] Specifically: The threaded tube is rotated within the inner cavity of the fastening screw 501. The external thread on its surface engages with the internal thread on the inner wall of the fastening screw 501, thus securing the threaded tube within the inner cavity of the insect-proof hose 3. This improves the connection stability between the diaphragm connector 503 and the insect-proof hose 3. As the diaphragm connector 503 connects to the insect-proof hose 3, the threaded tube penetrates the inner cavity of the sheath. The sheath enhances the sealing of the connection between the diaphragm connector 503 and the insect-proof hose 3, preventing liquid backflow. Several sets of fixing sleeves 6 wrap around the surface of the insect-proof hose 3, thereby fixing the insect-proof hose 3 within the inner cavity of the insect-proof shell 1 and preventing it from becoming disorganized. In the inner cavity of the insect-proof shell 1, the insect-proof liquid flowing out from the holes 4 on its surface flows evenly onto the sponge plate 2. The limiting sleeve on the side of the insect-proof shell 1 limits and fixes the insect-proof hose 3, keeping it in a fixed position inside the insect-proof shell 1. The insect-proof liquid flowing down from the replenishment component 5 can quickly flow into the insect-proof hose 3. The sealing ring 7 can improve the sealing between the fastening screw 501 and the connecting gasket 502, thereby improving the connection sealing between the membrane connector 503 and the insect-proof hose 3. Inserting a sealing plug into the inner cavity of the injection tube 505 can prevent external dust and impurities from entering the injection tube 505 and causing blockage. After removing the sealing plug, the insect-proof medicine can be injected into the replenishment component 5 through the syringe.

[0029] The working principle of this utility model is as follows: the insect-proof hose 3 is placed in the inner cavity of the insect-proof shell 1. After the drug replenishment component 5 is connected to the insect-proof hose 3, the film-penetrating connector 503 passes through the insect-proof film. The grain warehouse management staff can remove the sealing plug, draw in an appropriate amount of insect-proof agent with a syringe, open the sealing valve 504, insert the syringe head into the inner cavity of the drug injection tube 505, and push the drug into the inner cavity of the drug injection tube 505 through the syringe. The drug enters the insect-proof hose 3 through the film-penetrating connector 503. Finally, the drug flows through the perforated 4 on the surface of the insect-proof hose 3 to the surface of the sponge board 2 to form an insect-proof line.
