Description

Technical Field

[0001] The utility model relates to the technical field of grain storage bins, in particular to a grain storage bin. Background Art

[0002] Grain storage silos are facilities used to store agricultural products such as grains and cereals. They are designed and built to protect grains from moisture, pests, mold and other hazards. The structure of the grain storage silo must be strong and stable and able to withstand the weight of the grain and the impact of the external environment.

[0003] A Chinese patent with the publication number CN203514903U discloses a welded airtight and heat-insulating grain silo. The existing ordinary steel plate silo cannot be airtight and cannot be fumigated on schedule. Grain is prone to insects during storage. Traditional steel plate silos do not have heat insulation function, so they cannot store grain for a long time. The welded airtight and heat-insulating grain silo consists of: a foundation, a silo roof, and a silo body connecting the foundation and the silo roof. The silo body consists of an outer silo board, an inner silo board, a heat-insulating material, and a silo column. The outer silo board is fixed to the inner silo board through a connector. The heat-insulating material is fixed between the inner silo board and the outer silo board. The silo column is fixed to the inner surface of the inner silo board by welding. The inner silo board is made of steel plates welded in a circumferential direction. The silo with airtight and heat-insulating functions is also suitable for oil storage. It is used for long-term storage of grain or oil.

[0004] The existing related technologies often have the following defects: in the actual use of the grain storage warehouse, after the grain is taken out of the warehouse, there will still be a small amount of grain particles and impurities on the ground, which requires the staff to spend a long time to achieve the aggregation and classification of the grain and impurities on the ground, reducing the use effect of the grain storage warehouse.

[0005] Therefore, the utility model provides a grain storage bin. Utility Model Content

[0008] The effect achieved by the above components is: the filter with a truncated cone structure can gather a small amount of grain. As the grain slides down the filter and gathers, impurities can fall onto the ground of the warehouse during the rolling process, thereby separating the grain and impurities.

[0009] Preferably, a screw ring is fixedly connected to the lower end of the filter screen, and a screw cover is threadedly connected to the side wall of the screw ring.

[0010] The effect achieved by the above components is that the collection of grain after the bucket is lifted can be realized by opening the screw cover on the screw ring.

[0011] Preferably, two draw ropes are fixedly connected to the upper side of the limiting ring, and the other ends of the draw ropes are fixedly connected to a handle.

[0012] The effect achieved by the above components is that the pull rope will drive the limit ring to be lifted from the ground, and the filter screen below the limit ring will also be lifted at the same time.

[0013] Preferably, two positioning blocks are fixedly connected to the side wall of the silo, and the interiors of the two positioning blocks are rotatably connected to rotating rods, and the ends of the two rotating rods close to each other are fixedly connected to pulleys, and the pull rope is located between the pulley and the silo.

[0014] The effect achieved by the above components is that the pull rope slides on the surface of the pulley to change the pulling direction of the pull rope.

[0015] Preferably, a retaining ring is fixedly mounted on the upper side of the silo, and a limiting frame is fixedly connected to the lower side of the silo.

[0016] The effect achieved by the above components is: the handle is put between the limit frame and the magazine tube, and the pull rope is put on the inner side of the limit frame, which can realize the support work of lifting the rear limit ring.

By pulling the handle, the collecting plate inside the chute can be pulled out, and the impurities inside the collecting plate can be centrally processed after being full of impurities.

[0019] Preferably, two connection blocks are fixedly connected to the side wall of the silo, the internal threads of the connection blocks are connected with bolts, and the lower ends of the bolts are fixedly connected with a circular plate.

[0020] The effect achieved by the above components is: push the collecting plate into the inner side of the slide groove, rotate the bolts inside the connecting block, the bolts will drive the circular plate to move to the position of the side wall of the collecting plate, and the limiting and shielding work of the collecting plate can be realized.

[0021] In summary:

[0031] The specific settings and functions of the aggregation structure 3 and the collection structure 4 are described in detail below.

[0032] Reference Figure 1-Figure 4 As shown, in this embodiment: the gathering structure 3 includes a limit ring 304 slidably mounted on the inner side of the silo 1, and a filter 305 is fixedly connected to the lower end of the limit ring 304, and the lower side of the filter 305 is a truncated cone structure. The truncated cone structure filter 305 can achieve the gathering of a small amount of grain. In the process of the grain sliding up and down on the filter 305 and gathering, the impurities can fall on the storage floor during the rolling process, thereby achieving the separation of grain and impurities.

[0033] The lower end of the filter screen 305 is fixedly connected with a screw ring 306, and the side wall of the screw ring 306 is threadedly connected with a screw cover 307. The screw cover 307 on the screw ring 306 can be opened to collect the grain after the bucket is lifted. Two pull ropes 301 are fixedly connected to the upper side of the limit ring 304, and the other end of the pull rope 301 is fixedly connected to a handle 302. The pull rope 301 will drive the limit ring 304 to be lifted from the ground, and the filter screen 305 below the limit ring 304 will also be lifted at the same time.

[0034] Two positioning blocks 308 are fixedly connected to the side wall of the silo 1. The inside of the two positioning blocks 308 is rotatably connected to a rotating rod 310. The ends of the two rotating rods 310 close to each other are fixedly connected to a pulley 309. The pull rope 301 is located between the pulley 309 and the silo 1. The pull rope 301 slides on the surface of the pulley 309 to change the pulling direction of the pull rope 301. A retaining ring 303 is fixedly installed on the upper side of the silo 1, and a limiting frame 311 is fixedly connected to the lower side of the silo 1. The handle 302 is placed between the limiting frame 311 and the silo 1, and the pull rope 301 is placed on the inner side of the limiting frame 311, which can support the lifting of the rear limiting ring 304.

[0035] Reference Figure 1-Figure 2 and Figure 5As shown, specifically, the collecting structure 4 includes a plurality of through holes 44 evenly opened on the lower side of the silo 1, a chute 43 is opened on the lower side of the silo 1, a collecting plate 41 is slidably connected to the inner wall of the chute 43, and a handle 42 is fixedly connected to the side wall of the collecting plate 41. After falling, the impurities can fall into the inner side of the collecting plate 41 along the through holes 44 for collection, and the handle 42 can be pulled out to realize the extraction of the collecting plate 41 inside the chute 43, and the centralized treatment of the impurities inside the collecting plate 41 after the impurities are collected can be realized. The side wall of the silo 1 is fixedly connected with two connecting blocks 45, and the internal thread of the connecting block 45 is connected with a bolt 46, and the lower end of the bolt 46 is fixedly connected with a circular plate 47. Push the collecting plate 41 into the inner side of the chute 43, rotate the bolt 46 inside the connecting block 45, and the bolt 46 will drive the circular plate 47 to move to the position of the side wall of the collecting plate 41, so as to realize the limiting and shielding work of the collecting plate 41.

[0036] Working principle: after the grain inside the silo 1 is taken out of the silo, when a small amount of grain and a large amount of impurities on the ground of the silo 1 need to be cleaned, two staff members can pull the rope 301 through the handle 302, and the rope 301 slides on the surface of the pulley 309 to change the pulling direction of the rope 301. At this time, the rope 301 will drive the limit ring 304 to be lifted from the ground, and the filter screen 305 under the limit ring 304 will also be lifted at the same time. The frustum-shaped filter screen 305 can realize the gathering of a small amount of grain. In the process of the grain sliding up and down on the filter screen 305 and gathering, the impurities can fall on the ground of the storage during the rolling process, thereby realizing the separation of grain and impurities. The separation work can be carried out, at this time, the handle 302 can be put on the position between the limit frame 311 and the silo 1, and the pull rope 301 will be put on the inner side of the limit frame 311, so as to support the limit ring 304 after lifting. At this time, the staff can place a collection bag under the screw ring 306 and open the screw cover 307 on the screw ring 306 to collect the grain after the bucket is lifted. The setting of the retaining ring 303 can effectively prevent impurities from falling into the inside of the silo 1 in rainy weather. By setting the gathering structure 3, the classification of residual grain and impurities inside the silo 1 and the collection of grain after the bucket is lifted are facilitated, which improves the performance of the silo 1 to a certain extent.

[0037] After falling, the impurities can fall into the inner side of the collecting plate 41 along the through hole 44 for collection. By pulling the handle 42, the collecting plate 41 inside the chute 43 can be pulled out, and the impurities inside the collecting plate 41 after being full of impurities can be centrally processed. The collecting plate 41 is pushed into the inner side of the chute 43, and the bolt 46 inside the connecting block 45 is rotated. The bolt 46 will drive the circular plate 47 to move to the position of the side wall of the collecting plate 41, so as to realize the limiting and shielding work of the collecting plate 41, and the limiting work of the collecting plate 41 after being folded can be realized. By setting the collecting structure 4, the centralized processing of impurities after screening is facilitated, and the performance of the silo 1 is further improved.
