Description

Technical Field

[0001] The utility model relates to the technical field of shallow silo grain transportation, in particular to a shallow silo grain transportation pipeline with a buffer box. Background Art

[0002] In some large grain storage sites, shallow silos are often used to store grain. Since shallow silos are relatively high, the grain entrance is often set at the top of the silo, so an attached grain elevator is installed on one side of the silo.

[0003] Since the height of the grain elevator discharge port is higher than the feed port of the shallow cylindrical silo, and the elevator is located on one side outside the shallow cylindrical silo, the connecting pipe between the grain elevator discharge port and the feed port of the shallow cylindrical silo is bent as a whole, that is, the pipe connecting the grain elevator discharge port is inclined, and the pipe connecting the feed port of the shallow cylindrical silo is vertical.

[0004] When grain passes through the pipeline, the speed of the grain will increase during the continuous falling process, which will cause the impact surface of the pipeline connected to the shallow silo feed port to be impacted and worn, which will increase the breakage rate of grain during transportation; with the continuous large-scale transportation of grain, the impact surface of the pipeline will be worn out, which will lead to grain leakage (the existing pipeline will be worn and damaged when transporting 5,000 tons of grain and needs to be replaced), and the service life is short. To this end, we proposed a shallow silo grain transportation pipeline with a buffer box. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a shallow round silo grain conveying pipeline with a buffer box.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A shallow cylindrical silo grain conveying pipeline with a buffer box includes a first connecting pipe connected to the discharge port of an elevator attached to the shallow cylindrical silo and a second connecting pipe connected to the feed port of the shallow cylindrical silo, wherein the second connecting pipe is in a vertical state, the first connecting pipe is in an inclined state, and the lower end of the first connecting pipe is connected to the upper end of the second connecting pipe, and the inner surface opposite to the upper end of the second connecting pipe and the lower end of the first connecting pipe is an impact surface.

[0008] An opening is formed in the tube wall of the second connecting tube where the impact surface is located, and a buffer cylinder is welded through the opening. The rear end of the buffer cylinder extends to the outside of the second connecting tube and is fixedly mounted with a sealing cover.

[0009] A push spring is fixedly installed in the middle of the inner surface of the sealing cover. The other end of the push spring is fixedly installed with a push plate. A limiting rod is welded to a part of the inner surface of the upper end of the second connecting pipe opposite to the impact surface. A limiting disc is welded to one end of the limiting rod facing the impact surface. The surface of the limiting disc away from the limiting rod is flush with the impact surface.

[0010] A number of buffer plates and wear-resistant plates are arranged between the push plate and the limiting disc. The buffer plates and the wear-resistant plates are arranged in a stacked manner in sequence, and the surfaces of adjacent buffer plates and wear-resistant plates are adhered by glue.

[0011] Preferably, the cross-section of the sealing cover is in a U shape, and fixing bolts are commonly installed between the side of the sealing cover and the outer surface of the rear end of the corresponding buffer cylinder.

[0012] Preferably, the outer ring surfaces of the buffer plate and the wear-resistant plate are both in contact with the inner surface of the corresponding buffer cylinder.

[0013] Preferably, a reference rod is welded at the center point of the surface of the push plate facing the push spring.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figure 1-3 , a shallow silo grain conveying pipeline with a buffer box, including a first connecting pipe 1 connected to the discharge port of the elevator attached to the shallow silo and a second connecting pipe 2 connected to the feed port of the shallow silo. The second connecting pipe 2 is in a vertical state, the first connecting pipe 1 is in an inclined state, and the lower end of the first connecting pipe 1 is connected to the upper end of the second connecting pipe 2. The inner surface of the upper end of the second connecting pipe 2 opposite to the lower end of the first connecting pipe 1 is the impact surface 201;

[0023] An opening is formed in the pipe wall of the second connecting pipe 2 where the impact surface 201 is located, and a buffer cylinder 3 is welded through the opening. The rear end of the buffer cylinder 3 extends to the outside of the second connecting pipe 2 and is fixedly installed with a sealing cover 4. The cross-section of the sealing cover 4 is in a U shape, and fixing bolts 5 are jointly installed between the side of the sealing cover 4 and the outer surface of the corresponding rear end of the buffer cylinder 3. When it is necessary to remove the sealing cover 4, just unscrew the fixing bolts 5.

[0024] A pushing spring 6 is fixedly installed in the middle of the inner surface of the sealing cover 4, and the other end of the pushing spring 6 is fixedly installed with a pushing plate 7. A limiting rod 9 is welded to a part of the inner surface of the upper end of the second connecting pipe 2 opposite to the impact surface 201. A limiting disc 10 is welded to one end of the limiting rod 9 facing the impact surface 201, and the surface of the limiting disc 10 away from the limiting rod 9 is flush with the impact surface 201;

[0025] A plurality of buffer plates 11 and wear-resistant plates 12 are arranged between the push plate 7 and the limit plate 10. The buffer plates 11 and the wear-resistant plates 12 are stacked in sequence, and the surfaces of adjacent buffer plates 11 and wear-resistant plates 12 are bonded together by glue. The outer annular surfaces of the buffer plates 11 and the wear-resistant plates 12 are in contact with the inner surface of the corresponding buffer cylinder 3. When the wear-resistant plate 12 is subjected to force, the buffer plate 11 to which the wear-resistant plate 12 is bonded will produce a certain deformation, thereby achieving buffering and shock reduction of grain.

[0026] A reference rod 8 is welded at the center point of the surface of the push plate 7 facing the push spring 6. The other end of the reference rod 8 passes through the spring 6 and the sealing cover 4 and extends to the outside of the sealing cover 4. The reference rod 8 is active relative to the sealing cover 4.

[0027] A limit head 13 is welded to one end of the reference rod 8 outside the sealing cover 4. When the limit head 13 is in contact with the outer surface of the sealing cover 4, the front surface of the push plate 7 is flush with the impact surface 201. The thickness of the whole formed by the buffer plate 11 and the wear-resistant plate 12 can be obtained by measuring the distance between the reference rod 8 and the sealing cover 4, thereby facilitating timely discovery of the specific condition of the whole formed by the buffer plate 11 and the wear-resistant plate 12 and timely replacement and maintenance.

[0028] To sum up: during use, as the grain enters the second connecting tube 2 through the first connecting tube 1, when the grain impacts the wear-resistant plate 12 due to changing the direction of movement, the wear-resistant plate 12 can firstly reduce the wear and consumption caused by the moving grain by virtue of its wear-resistant performance; at the same time, under the impact of the grain, the buffer plate 11 on the rear side of the wear-resistant plate 12 can play a certain role in buffering and shock absorption, reducing the intensity of the reaction force received by the grain in the process of impacting the wear-resistant plate 12, thereby reducing the breakage rate caused by impact during transportation.

[0029] When the surface of the wear-resistant plate 12 is slowly worn away, the push spring 6 will ensure that the surface of the wear-resistant plate 12 is always flush with the impact surface 201 by stretching, thereby preventing the moving grain from causing impact wear on the inner surface of the buffer cylinder 3; when the wear-resistant plate 12 at the front side is completely worn away, the buffer plate 11 adjacent to the wear-resistant plate 12 will replace the disappeared wear-resistant plate 12 to achieve buffering and shock absorption of the grain, that is, to protect the moving grain until the buffer plate 12 disappears and the wear-resistant plate 12 adhered to the other side moves to the impact surface 201 and is put into use, thereby achieving automatic replenishment of the wear-resistant plate 12 and the buffer plate 11 under the pushing action of the push spring 6.

[0030] With the long-term use of the entire pipeline, the use status of the buffer plate 11 and the wear-resistant plate 12 can be judged by observing the distance between the limit head 13 and the sealing cover 4, which is conducive to timely replacement of the consumables in the buffer cylinder 3, namely the buffer plate 11 and the wear-resistant plate 12, and the sealing cover 4 can be opened or closed by removing and installing the fixing bolts 5 during the replacement process. The operation is simple and convenient, and easy to maintain.

[0031] That is, based on the setting of multiple wear-resistant plates 12, the service life of the pipeline can be improved, and based on the buffer plate 11, the breakage rate of grain in the process of conveying grain can be reduced. In addition, when the wear-resistant plates 12 and the buffer plates 11 are worn out after long-term use, it can be easy to discover. After discovery, the replacement of the wear-resistant plates 12 and the buffer plates 11 is simple and convenient, which is conducive to promotion and use.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
