Description

Technical Field

[0001] The utility model relates to the technical field of grain bins, and more specifically to a telescopic device for discharging grain at a low position on the side wall of a grain bin with energy conservation and loss reduction. Background Art

[0002] In the existing technology of discharging grain from the side wall of a grain bin, an electric gate is usually set at the grain discharging port to control the opening and closing of the grain discharging port. Especially for the low-position grain discharging port on the side wall of a shallow silo, since the low-position grain discharging port is not very high from the ground, during the process of discharging grain, every time the vehicle moves, the operating workers have to repeatedly go to the control box against the wall (the gate control switch of the low-position grain discharging port is usually installed on the wall beside the grain discharging port) to start or close the electric gate of the grain discharging port. During use, due to the frequent switching of the gate, the spiral bearing of the electric gate of this grain discharging port is severely worn, and it often occurs that the gate is displaced and jammed, resulting in the electric gate not being able to be opened or closed tightly. Sometimes, this will also cause the situation of not being able to discharge grain or leakage of grain from the low-position port, which will not only increase the workload of the operating workers, but also affect the progress of the grain rotation on the same day.

[0003] In addition, since the grain discharged from the low-position port of the shallow silo is not very high from the ground, an open intermediate chute was originally connected at the grain discharging port to discharge grain. Since the intermediate chute does not adopt a dust suppression and protection device, the impurities and dust in the grain flowing out from the low-position port will fly everywhere with the wind. This will not only cause wind loss of the grain, but also cause dust pollution to the surrounding environment and affect the nearby air and other problems. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a telescopic device for discharging grain at a low position on the side wall of a grain bin with energy conservation and loss reduction.

[0005] The utility model adopts the following technical solutions:

[0006] A telescopic device for discharging grain at a low position on the side wall of a grain bin with energy conservation and loss reduction, including a fixed cover fixedly installed at the grain discharging port on the side wall of the grain bin. An unloading pipe is fixedly connected to the fixed cover and is arranged obliquely downward. The unloading pipe is composed of several telescopic sleeves. A nitrogen telescopic rod for controlling the telescopic of the telescopic sleeve is also arranged on the unloading pipe. The end of the unloading pipe is a grain discharging port, and a manual valve for controlling the discharging of the grain discharging port is arranged in the grain discharging port.

[0007] Further, the unloading pipe includes a first telescopic pipe, a second telescopic pipe and a third telescopic pipe. The first telescopic pipe is fixedly connected to the fixed cover. The second telescopic pipe is sleeved on the first telescopic pipe. The third telescopic pipe is sleeved on the second telescopic pipe. The fixed end of the nitrogen telescopic rod is locked on the side wall of the first telescopic pipe, and the telescopic end of the nitrogen telescopic rod is locked on the side wall of the third telescopic pipe.

[0008] Preferably, the third telescopic pipe is an obtuse-angled bent pipe, and the bending direction of the third telescopic pipe is downward.

[0009] Preferably, a grain outlet pipe is fixedly connected to the end of the third telescopic pipe, and the manual valve is arranged in the grain outlet pipe.

[0010] Preferably, a stretching handle is arranged on the side wall of the third telescopic pipe.

[0011] Furthermore, a discharge hopper with a wider top and a narrower bottom is fixedly connected to the grain outlet.

[0012] Furthermore, the fixed cover comprises a rectangular frame and a transition cover. The rectangular frame is fixedly connected to the grain unloading opening, and the transition cover is fixedly connected to the grain unloading pipe.

[0013] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

[0014] The present invention can temporarily control the opening and closing of grain discharging through the manual valve, thereby avoiding mechanical loss and power loss caused by frequent opening and closing of the electric gate in the grain unloading opening. At the same time, the grain unloading pipe adopts a telescopic sleeve structure, and a nitrogen gas telescopic rod is used as a control component for telescopic movement, so that the up and down telescopic movement can be stopped immediately when pulled, with simple and convenient operation, energy conservation and environmental protection, and no need for additional electric energy to provide power. Moreover, during operation, the grain discharging length can be adjusted at any time according to actual needs, so that when discharging grain, the discharge hopper can be close to the conveying equipment or the grain truck, reducing the grain discharging drop and solving the problems of wind loss and dust dispersion pollution to the surrounding environment caused by grain discharging at a low-position opening.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following describes the specific embodiments of the embodiments of the present invention with reference to the drawings.

[0019] Refer to Figure 1 and Figure 2, An energy-saving and loss-reducing telescopic device for discharging grain at the lower position of the side wall of a granary, which includes a fixed cover 10 fixedly installed at the grain discharging port on the side wall of the granary. A discharging pipe 20 is fixedly connected to the fixed cover 10 and is arranged obliquely downward. The discharging pipe 20 is composed of several telescopic sleeves, and a nitrogen telescopic rod 30 for controlling the telescopic movement of the telescopic sleeves is also provided on the discharging pipe 20. The end of the discharging pipe 20 is a grain outlet, and a manual valve 40 for controlling the grain discharging at the grain outlet is arranged in the grain outlet.

[0020] Specifically, referring to Figure 1 and Figure 2 , the fixed cover 10 is composed of a rectangular frame 11 made of stainless steel and a transition cover 12 through bolt locking or welding. In this embodiment, one end port of the rectangular frame 11 is fixedly connected to the existing lower-position grain discharging port on the side wall of the granary by bolt locking, and the other end port of the rectangular frame 11 is fixedly connected to the transition cover 12 by bolt locking. One end of the transition cover 12 is a rectangular opening, and the other end is transitioned into a circular opening, and the transition cover 12 is gradually formed at a certain inclination angle to facilitate the self-flow of grain discharging.

[0021] Referring to Figure 2 , the discharging pipe 20 includes a first telescopic pipe 21, a second telescopic pipe 22, a third telescopic pipe 23 and a grain discharging pipe 24. The first telescopic pipe 21 is fixedly connected to the transition cover 12 by bolt fixing. The second telescopic pipe 22 is sleeved on the first telescopic pipe 21, the third telescopic pipe 23 is sleeved on the second telescopic pipe 22. The third telescopic pipe 23 is an obtuse-angled bent pipe, and the bending direction of the third telescopic pipe 23 is bent downward. The grain discharging pipe 24 is fixedly connected to the end of the third telescopic pipe 23, and the manual valve 40 is arranged in the grain discharging pipe 24. The fixed end of the nitrogen telescopic rod 30 is locked on the side wall of the first telescopic pipe 21, and the telescopic end of the nitrogen telescopic rod 30 is locked on the side wall of the third telescopic pipe 23.

[0022] Referring to Figure 2 , in order to facilitate the stretching of the discharging pipe 20, two stretching handles 51 are also provided on the side wall of the third telescopic pipe 23; in order to facilitate the handling of the present utility model, two handling handles 52 are also welded on the side wall of the rectangular frame 11. In addition, in this embodiment, the structures of the manual valve 40 and the nitrogen telescopic rod 30 are existing conventional technologies and are mature products already available on the market, so their structures and working principles will not be further described here. In order to further control the air consumption loss and dust dispersion during grain discharging, a feeding hopper 25 with a wider upper part and a narrower lower part is fixedly connected to the end of the grain discharging pipe 24, that is, at the grain outlet.

[0023] Referring to Figure 1 and Figure 2, during the operation of the present utility model, for the low-position grain discharging opening on the side wall of the granary, the electric gate originally arranged in the grain discharging opening only needs to be opened once at the start of the operation every day and then closed once at the end of the operation on the same day. During the grain discharging period, during the transition interval of each vehicle for loading grain, the manual valve 40 can be used to temporarily open and close the grain discharging, thereby avoiding the mechanical loss and power loss caused by the frequent opening and closing of the electric gate.

[0024] In addition, the grain discharging pipe 20 of the present utility model adopts a telescopic sleeve structure, and the nitrogen gas telescopic rod 30 is used as the control component for telescopic movement. As long as the stretching handle 51 is pushed up or down, the up and down telescopic movement can be realized, that is, it stops immediately when pulled, with simple and convenient operation, energy conservation and environmental protection, without the need for additional electric power to provide power, and during the operation, the grain discharging length of the device can be adjusted at any time according to the actual situation, so that during grain discharging, the discharging hopper 25 can be close to or adjacent to the conveying equipment or the grain truck, reducing the grain discharging drop. Coupled with the structural characteristics of the discharging hopper 25, the problems of wind loss and dust dispersion pollution to the surrounding environment caused by grain discharging from the low-position opening can be solved to the greatest extent.

[0025] Finally, from the fixed cover 10 to the grain discharging pipe 20 and until the discharging hopper 25 at the end of the present utility model, the overall connection forms a certain inclination angle, with multiple downward inclinations. During grain discharging, the self-flow characteristics of the grain can be utilized, and most of the grain discharging operation from the warehouse can be completed by relying on self-flow without power.

[0026] The above is only the specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall belong to the act of infringing the protection scope of the present utility model.
