Description

Technical Field

[0001] The invention relates to the technical field of granary unloading, and in particular to a silo top fixed unloading device. Background Art

[0002] Granaries are buildings or facilities used to store grain, which play a very important role in ensuring food safety, stabilizing market prices, and responding to emergencies. Granaries can be of various types, depending on their purpose and size, including traditional above-ground granaries, modern large steel-structured granaries, underground or semi-underground granaries, and silos. In order to facilitate the rapid loading and unloading of large quantities of grain, silos are usually used to store grain.

[0004] Although the above application and the prior art allow grain trucks to unload materials only by queuing outside the granary without entering the granary, thereby reducing the risk of grain trucks damaging grain and eliminating the safety hazards to personnel caused by grain trucks frequently entering the granary, during the unloading process, the grain will always pile up in the middle, resulting in a situation where the middle is high and the two sides are low, thereby affecting the storage capacity of the granary, and due to the height difference of the granary, when the grain enters the granary, dust will be generated, and the outer surface of the grain will be damaged during the descent due to the height difference, and during the loading and unloading of the grain, the grain will bridge the inner wall of the granary, resulting in uneven grain filling inside the granary, thereby affecting the storage effect of the granary, so we propose a fixed unloading device on the top of the granary.

[0041] When the distance between the regulating tube 22 and the bottom of the granary needs to be adjusted, the cylinder 51 is started, and the cylinder 51 drives the fixed plate 521 to move through the telescopic rod 52, so that the fixed plate 521 drives the support plate 151 to move through the U-shaped plate 522, and then the support plate 151 drives the telescopic tube 15 to move up and down, so that the telescopic tube 15 drives the regulating tube 22 to move up and down, so that there is no height difference after the granary flows out of the regulating tube 22 to cause dust and damage to the grain surface;

[0042] For specific embodiment 3, please refer to Figures 1 to 11 According to a silo top fixed unloading device provided in the second specific embodiment, this embodiment provides a further technical solution:

[0043] The knocking assembly 3 includes four rotating cylinders 31 rotatably connected to the inside of the driving box 12, the inside of the four rotating cylinders 31 are all provided with second key grooves 311, the inside of the four rotating cylinders 31 are all slidably connected with telescopic cylinders 32, the surface of the telescopic cylinder 32 is fixedly connected with a half gear 321 and a key block 322, the key block 322 is slidably connected to the inside of the second key groove 311, the inside of the knocking box 13 is provided with a plurality of moving grooves 131, the knocking assembly 3 also includes a plurality of sliders 33 slidably connected to the inside of the knocking box 13, the tops of the plurality of sliders 33 are all fixedly connected with tooth plates 331, the tooth plates 331 are meshed with the half gears 321 for transmission, one end of the tooth plates 331 is fixedly connected with a buffer ring 332, the knocking assembly 3 also includes a plurality of fixed sliders 33 fixedly connected to the inside of the knocking box 13 The fixed cylinder 34, the interiors of the plurality of fixed cylinders 34 are all fixedly connected with springs 341, the interiors of the plurality of fixed cylinders 34 are all slidably connected with extension cylinders 342, one end of the extension cylinder 342 is fixedly connected with one end of the spring 341, one end of the slider 33 is fixedly connected with one end of the extension cylinder 342 away from the spring 341, the driving assembly 4 comprises a first active pulley 41 fixedly connected to the surface of the driving rod 211 and a first driven pulley 42 fixedly connected to the surface of one of the rotating cylinders 31, the first active pulley 41 and the first driven pulley 42 are transmitted via a first belt 411, the driving assembly 4 also comprises a second driven pulley 43 fixedly connected to the surfaces of the four rotating cylinders 31, the four second driven pulleys 43 are transmitted via a second belt 431;

[0044] It should be noted that the first driving pulley 41 can be replaced by a first driving sprocket, the first belt 411 can be replaced by a first chain, the first driven pulley 42 can be replaced by a first driven sprocket, the first driving sprocket drives the first driven sprocket to rotate through the first chain, the second driven pulley 43 can be replaced by a second driven sprocket, the second belt 431 can be replaced by a second chain, the second driven sprocket drives the other second driven sprocket to rotate through the second chain, and the transmission mode of the driving assembly 4 is not limited here;

[0045] When it is necessary to avoid the bridging phenomenon inside the granary, the driving rod 211 drives the first active pulley 41 to rotate when it rotates, so that the first belt 411 drives the first driven pulley 42 to rotate, and then the second driven pulley 43 drives the rotating cylinder 31 to rotate through the second belt 431, so that the rotating cylinder 31 drives the half gear 321 to rotate through the telescopic cylinder 32, and the half gear 321 drives the tooth plate 331 to move through the engagement, so that the tooth plate 331 squeezes the extension cylinder 342 through the slider 33, and then the spring 341 is deformed.

[0046] Working principle: When in use, the device is installed on the top of the granary. When unloading is required, the grain is unloaded into the inside of the feed barrel 1 through the feed assembly 11, and flows into the telescopic tube 15 through the cone mouth 141. When the feeding angle needs to be adjusted, the first motor 21 is started, and the first motor 21 drives the turntable 223 to rotate through the driving rod 211, so that the turntable 223 drives the adjusting tube 22 to rotate through the rotating plate 222, and then the adjusting tube 22 rotates at the bottom of the telescopic tube 15 through the annular piece 221, so that the grain enters the adjusting tube 22 through the telescopic tube 15. Through the rotation of the adjusting tube 22, the grain is dispersed to different inner walls of the granary, thereby preventing the grain from being accumulated in the middle of the granary. When the distance between the adjusting tube 22 and the bottom of the granary needs to be adjusted, the cylinder 51 is started, and the cylinder 51 drives the fixed plate 521 to move through the telescopic rod 52, so that the fixed plate 521 drives the support plate 151 to move through the U-shaped plate 522, and then the support plate 151 drives the telescopic tube 15 to move up and down. The telescopic tube 15 drives the regulating tube 22 to move up and down, so that there will be no height difference after the grain flows out of the regulating tube 22 to cause dust and damage to the grain surface. In the process of moving the regulating tube 22, the telescopic rod 52 always drives the knocking box 13 to move. When it is necessary to avoid the bridge phenomenon inside the grain bin, the driving rod 211 drives the first active pulley 41 to rotate when rotating, so that the first belt 411 drives the first driven pulley 42 to rotate, and then the second driven pulley 43 drives the second belt 431 to drive the first driven pulley 42 to rotate. The rotating cylinder 31 is rotated, so that the rotating cylinder 31 drives the half gear 321 to rotate through the telescopic cylinder 32, and the half gear 321 drives the tooth plate 331 to move through the engagement, so that the tooth plate 331 squeezes the extension cylinder 342 through the slider 33, thereby causing the spring 341 to deform. When the half gear 321 and the tooth plate 331 are no longer engaged, the spring 341 restores its shape and drives the tooth plate 331 to move back and forth, so that the buffer ring 332 and the surface of the granary knock against each other, thereby avoiding the bridging phenomenon of grain on the inner wall of the granary.
