Description

Technical Field

[0001] This utility model belongs to the field of grain storage technology, and specifically relates to a grain storage pressure pipe device. Background Technology

[0002] Grain storage and handling operations require localized ventilation and sampling of the grain during the storage process. The depth of the insertion pipe is determined according to actual needs. The insertion pipes are connected by threads. After each section is inserted, the second section is connected and the insertion continues (each section is 1.2 meters long) until the grain layer is reached.

[0003] Currently, the manual clamping and extraction tool requires two operators. Insufficient clamping force poses safety risks, necessitating two people standing on either side to simultaneously press down the lever. It is also unusable in confined spaces at corners. Furthermore, incompatible connections between the suction tube, sampling tube, and ventilation tube, resulting in loose connections and compromised sealing, leads to poor suction performance. Utility Model Content

[0004] The purpose of this invention is to provide a grain storage pressure pipe device to overcome the shortcomings of the above-mentioned technology.

[0005] To achieve the above objectives, this utility model provides a grain storage pipe pressing device, including a clamping sleeve one, a clamping sleeve two, an air pipe connector, and a working pipe. Both clamping sleeve one and clamping sleeve two are semi-circular in shape. Clamping sleeve one and clamping sleeve two are located on opposite sides of the working pipe, and are arranged vertically. The inner surfaces of both clamping sleeve one and clamping sleeve two are provided with slots, in which wear-resistant bushings are embedded, and these bushings wrap around the surface of the working pipe. A bolt one is provided on clamping sleeve one, and a bolt two is provided on the air pipe connector. Bolt one and bolt two are connected by a chain. The bottom of the air pipe connector is inserted into the working pipe. A horizontal bar is connected to one end of the surface of clamping sleeve one, and a vertical bar is fixedly connected to the other end of the horizontal bar. A force-applying sleeve is provided on the horizontal bar. A bushing is provided on clamping sleeve two, and the bushing is fitted onto the surface of a connecting shaft. One end of the connecting shaft is fixedly connected to the bottom of the vertical bar, and the other end of the connecting shaft is connected to a handle.

[0006] Preferably, the cross-sectional shape of the wear-resistant bushing is an isosceles trapezoid.

[0007] Preferably, the number of bolt one, bolt two, and chain are all two.

[0008] Preferably, the bushing is provided with a reinforcing rod, one end of which is fixedly connected to a vertical rod, and the other end of which is provided with a reinforcing sleeve, which is fitted onto the surface of the connecting shaft.

[0009] The beneficial effects of this utility model are: 1. When it is necessary to press in the working tube, clamping sleeve one and clamping sleeve two are put on the surface of the working tube, and the handle is pressed down. Under the setting of the connection structure, clamping sleeve one and clamping sleeve two will generate opposite forces, which can hold the working tube tightly and press it down at the same time. Each section of the working tube is connected by threads and is equipped with wear-resistant bushings, which can protect the working tube and increase friction to prevent the device from slipping. After the bottom of the working tube is in place, the bottom of the air pipe connector is put on the top of the working tube, and the air pipe of the grain suction machine is connected to the top of the air pipe connector. The grain suction machine is then operated for operation.

[0010] 2. When it is necessary to lift the working pipe, the entire device can be flipped over so that clamping sleeve one is located under clamping sleeve two. The air pipe connector can be disassembled by unscrewing one bolt. The air pipe connector can be suspended naturally under the action of a chain. Clamping sleeve one and clamping sleeve two can be fitted onto the surface of the working pipe. Lifting the handle upwards will complete the lifting of the working pipe.

[0011] 3. This device can be operated by a single person, saving manpower and solving the problem of limited operating space in narrow and corner areas; the wear-resistant bushing adopts an embedded structure design, which is more stable and easier to replace; this structure can simultaneously realize the functions of pressing in the working tube and pulling out the working tube.

The inner surfaces of both clamping sleeve 1 and clamping sleeve 2 are provided with slots 5, into which wear-resistant bushings 6 are embedded, covering the surface of the working pipe 4. A bolt 7 is provided on clamping sleeve 1, and a bolt 8 is provided on the air pipe connector 3. Bolt 7 and bolt 8 are connected by a chain 9. The bottom of the air pipe connector 3 is inserted into the working pipe 4. The surface of clamping sleeve 1... One end of the horizontal bar 10 is connected to the vertical bar 11, and the other end of the horizontal bar 10 is fixedly connected to the vertical bar 11. The horizontal bar 10 is provided with a force-applying sleeve 12. Depending on the actual use environment or other conditions, the force-applying rod can be inserted into the force-applying sleeve 12 to further increase the stability of the device. The clamping sleeve 2 is provided with a bushing 13, which is fitted onto the surface of the connecting shaft 14. One end of the connecting shaft 14 is fixedly connected to the bottom of the vertical bar 11, and the other end of the connecting shaft 14 is connected to the handle 15. Through the connection structure of the horizontal bar 10 and the vertical bar 11, when the handle is pressed down, the clamping sleeve 1 and the clamping sleeve 2 generate opposite forces, tightly wrapping the working tube 4. The wear-resistant bushing 6 increases the friction, which helps to improve the use effect.

[0018] The wear-resistant bushing has an isosceles trapezoidal cross-section.

[0019] The number of bolts 7, bolt 8, and chain 9 are all two, which increases the stability of the air pipe connector 3.

Press down the handle 15. With the connection structure, clamping sleeve 1 and clamping sleeve 2 will generate opposite forces, which can hold the working tube 4 tightly while pressing it down. Each section of the working tube 4 is connected by threads and is equipped with a wear-resistant bushing 6, which can protect the working tube 4 and increase friction to prevent the device from slipping. After the bottom of the working tube 4 is in place, the bottom of the air pipe connector 3 is fitted onto the top of the working tube 4, and the air pipe of the grain suction machine is connected to the top of the air pipe connector 3. The grain suction machine is then operated for operation.

[0022] When it is necessary to lift the working pipe 4, the entire device can be flipped over so that clamping sleeve 1 is located under clamping sleeve 2. The air pipe connector 3 can be disassembled by screwing on a bolt 7. The air pipe connector 3 can be suspended naturally under the action of a chain 9, so that clamping sleeve 1 and clamping sleeve 2 are fitted on the surface of the working pipe 4.
