Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of storage equipment, in particular to a deep-layer fixed-point fumigation and pesticide application device. Background Art
[0002] Grain storage warehouses are rapidly developing towards larger, more intensive structures. Economically efficient, high-capacity warehouses like "tall flat warehouses" and "shallow round silos" are becoming the mainstream of the future warehousing industry. However, as storage capacity and height increase, this inevitably leads to decreased grain pile permeability, severe automatic grain grading, and limited fumigation effectiveness. This can lead to insect infestations in the lower and middle portions of the warehouse, resulting in abnormal grain heating. Based on past experience, there are two approaches to addressing this situation: 1. Fumigation of the entire warehouse; 2. Localized fumigation of infested areas. Fumigation of the entire warehouse achieves better results, but is more expensive and does not meet the overall requirements of green grain storage. The advantages of local fumigation treatment methods for insect infestation sites are relatively low cost and less pollution. However, the disadvantages are that the site of insect infestation is difficult to determine accurately. Even if the location is determined, it is difficult to apply pesticides to the lower part of the grain pile. The fumigation process is not controllable. It takes at least 10 days of routine operation to evaluate whether the fumigation treatment location is correct, which can easily lead to treatment failure and miss the best fumigation operation window.
[0003] Therefore, it is necessary to design a deep fixed-point fumigation and pesticide application device. Utility Model Content
[0004] In view of the defects in the prior art, the utility model provides a deep fixed-point fumigation and pesticide application device.
[0005] The technical solution adopted by the utility model is: a deep fixed-point fumigation and pesticide application device, comprising a cylinder, a top traction rope is arranged on the top of the cylinder, a wedge-shaped insertion part is arranged on the bottom, and an openable and closable cover plate is arranged on the bottom surface of the wedge-shaped insertion part; a plurality of air holes are arranged on the cylinder.
[0006] In order to better realize the present invention, a traction ring is provided at the bottom of the side of the cylinder.
[0007] In order to better realize the present invention, a reinforcing rib is provided on the side of the cylinder, and the traction ring is connected to the bottom of the reinforcing rib.
[0008] In order to better realize the utility model, the air vent is in the shape of a trumpet with a small inner side and a large outer side.
[0009] In order to better realize the present invention, the top traction rope includes a sheath connected to the cylinder, a reinforcing steel rope is arranged in the sheath, and a clamping block is arranged at the lower end of the reinforcing steel rope.

[0011] In order to better realize the present invention, a gas sampling tube is further provided in the sheath, and the lower end of the gas sampling tube is communicated with the cylinder.
[0012] The beneficial effects of the present invention are embodied in that the deep fixed-point fumigation and pesticide application device of the present invention cooperates with the cylinder, the top traction rope, the wedge-shaped insertion part, the openable and closable cover plate and the air vents.

DETAILED DESCRIPTION
[0018] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.
[0019] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art in the field of this utility model.
[0020] Example:
[0021] like Figures 1 to 3 As shown, the deep-level fixed-point fumigation and pesticide application device of the present invention comprises a cylinder 1, a top traction rope 2 is provided at the top of the cylinder 1, a wedge-shaped insertion portion 4 is provided at the bottom, and an openable cover 5 is provided on the bottom surface of the wedge-shaped insertion portion 4; a plurality of air holes 8 are provided on the cylinder 1. The deep-level fixed-point fumigation and pesticide application device of the present invention, through the cooperation of the cylinder 1, the top traction rope 2, the wedge-shaped insertion portion 4, the openable cover 5 and the air holes 8, when in use, the openable cover 5 is opened, the fumigant is placed into the cylinder 1, and the openable cover 5 is closed. The cylinder 1 is inserted into the grain pile to the depth to be fumigated using the wedge-shaped insertion portion 4, and the fumigant is volatilized to the area to be fumigated in the grain pile through the air holes 8. After the fumigation is completed, the top traction rope 2 is held to pull out the entire device, and the openable cover 5 can be opened to clean the drug residue, replace the fumigant, etc., which has the advantages of simple structure, precise fumigation and low pollution. It should be noted that the structure of the openable cover 5 is similar to that of the battery cover of the remote control panel, and will not be described in detail.
[0022] As a preference, a traction ring 7 is provided at the bottom of the side of the cylinder 1. After such a design, when the entire device is inserted into the grain pile, a negative pressure suction auxiliary application device with a "Y"-shaped protruding mechanism 15 at the top can be used to match the bottom "Y"-shaped protruding device with the traction ring 7, such as Figure 3 The negative pressure metal tube 14 of the negative pressure suction auxiliary spraying device is connected with a "Y"-shaped protruding mechanism 15. The "Y"-shaped protruding mechanism 15 cooperates with the traction ring 7. On the one hand, downward force can be applied to assist the cylinder 1 to be inserted into the grain pile. On the other hand, the space formed by starting the negative pressure device 14 to use the negative pressure to suck out the grain at the bottom of the grain pile is more convenient to apply downward force, insert the auxiliary cylinder 1 into the grain pile, and facilitate the insertion of the cylinder 1. Further preferably, a reinforcing rib 6 is provided on the side of the cylinder 1, and the traction ring 7 is connected to the bottom of the reinforcing rib 6. After such a design, the connection strength of the traction ring 7 is greatly improved, which can prevent the traction ring 7 from damaging the cylinder 1 during the force application process.
[0023] Preferably, the air holes 8 are trumpet-shaped, with a smaller inner side and a larger outer side. The inner side of the air holes 8 is generally configured with an effective diameter smaller than the effective diameter of the grain particles. This design prevents grain from entering the cylinder 1 (while also preventing the air holes from becoming clogged during penetration into the grain pile). Furthermore, the trumpet-shaped shape facilitates faster and more uniform contact of the fumigant with the grain after it overflows from the air holes 8, thereby improving fumigation efficiency.
[0024] Preferably, the top traction rope 2 includes a sheath 9 connected to the cylinder 1, a reinforcing steel rope 10 is arranged inside the sheath 9, and a clamping block 13 is provided at the lower end of the reinforcing steel rope 10. This design strengthens the mechanical strength of the entire top traction rope 2 and prevents the top traction rope 2 from breaking when the cylinder 1 is pulled out by holding the top traction rope 2. It should be noted that Figure 2 In order to clearly show the structure of each component, the spacing is left relatively large. In the actual product, the reinforcing steel cable 10, the signal line 11 and the gas sampling tube 12 are squeezed together, and the card block 13 can be stuck into the preset card slot on the top of the cylinder 1.
[0025] Preferably, a signal line 11 is provided in the sheath 9, and a temperature sensor is provided at the lower end of the signal line 11. This design makes it easy to detect the temperature around the barrel 1, and to monitor the temperature changes of the grain pile around the application site, so as to dynamically grasp the treatment effect of the entire fumigation process.
[0026] Preferably, a gas sampling tube 12 is provided in the sheath 9, the lower end of which is connected to the cylinder 1. With this design, the fumigant can be output to the gas detection end through the gas sampling tube 12, thereby conveniently detecting the amount of fumigant and facilitating timely regulation by the staff.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
