Description

Technical Field

[0001] The invention relates to the technical field of warehousing logistics, and in particular to a valve-controlled anti-grading material distribution device for a cylindrical silo. Background Art

[0002] As a vertical cylindrical storage facility specially used for storing bulk grain, silos currently basically adopt a central feeding mode. However, since the distance between the central discharge port of the silo and the bottom of the silo is usually around 20 to 50 meters, such a large height difference makes the grain enter the silo. On the one hand, it is affected by gravity, and on the other hand, due to the differences in the size and density of grain particles, it is very easy to be stratified and graded. When grains with different characteristics are naturally accumulated in the silo, different layers will be formed, resulting in serious uneven distribution of grain.

[0003] In addition, grain falling from a height will cause it to break. This breakage will not only reduce the quality of the grain and increase the amount of grain loss, but also the stability of the broken grain during storage will be greatly reduced, which can easily cause problems such as insect pests and mildew, further reducing the quality of the grain and being extremely detrimental to the safe storage of grain. At the same time, uneven grain distribution will also affect the performance and quality stability of product processing, and may even cause the product to fail to meet relevant standard requirements.

[0004] Therefore, it is necessary to provide a valve-controlled anti-grading material distribution device for a silo, aiming to solve the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide a valve-controlled anti-grading material distribution device for a silo, which can effectively solve the problems in the background technology.

[0008] As a further improvement of the above solution, a servo motor is fixedly mounted on the outer side of the connecting seat, and the output end of the driving shaft is fixedly connected to one of the driving shafts via a coupling.

[0009] As a further improvement of the above solution, a collecting bucket is fixedly connected to the top of the connecting seat, and a sealing block is symmetrically fixedly connected to the inside of the collecting bucket.

[0010] As a further improvement of the above scheme, the mixing component includes a support block evenly fixedly connected to the outer side of the movable seat, the interior of the support block is symmetrically fixedly connected with a mounting sleeve, the interior of the mounting sleeve is rotatably connected with a mounting shaft, and the bottom of the mounting shaft is symmetrically fixedly connected with a stirring block.

[0011] As a further improvement of the above scheme, a fixed plate is fixedly connected to the outer side of the collecting bucket, two annular grooves are provided at the bottom of the fixed plate, teeth are evenly distributed on the groove walls of the annular grooves, and a driving wheel is fixedly connected to the top of the mounting shaft, and the driving wheel is meshed with the annular grooves.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 10 As shown, the present invention provides an embodiment: a valve-controlled anti-grading material distribution device for a cylindrical silo, comprising a material drop pipe 1, and further comprising: The blanking assembly 2 includes a movable seat 21 slidably connected to the outside of the blanking tube 1, the outside of the movable seat 21 is evenly fixedly connected to a blanking bin 22, the inside of the blanking tube 1 is slidably connected to a diverter plate 24, the movable seat 21 and the diverter plate 24 are rotatably connected, a spiral groove 25 is opened on the outside of the blanking tube 1, the inside of the blanking tube 1 is evenly fixedly connected to a spirally distributed slider 26, and the bottom of the blanking bin 22 is fixedly connected to a blanking head 1 231, a blanking head 232 and a blanking head 3 233 in sequence; The walking assembly 3 includes a connecting seat 32 fixedly connected to the top of the movable seat 21, the connecting seat 32 is symmetrically rotatably connected to a driving shaft 36, the outer side of the driving shaft 36 is fixedly connected to a spur gear 38, the inside of the blanking tube 1 is symmetrically fixedly connected to a rack 33, the spur gear 38 and the rack 33 are meshed with each other, the outer side of the blanking tube 1 is symmetrically provided with vertical grooves, and the rack 33 is fixedly connected to the inner wall of the vertical groove; The mixing component 4 is located outside the movable seat 21 and is used to mix the materials after distribution.

[0030] In actual application of the embodiment of the present invention, the material enters from the top of the drop tube 1, the diverter plate 24 performs preliminary diversion of the material, and the drive shaft 36 in the walking assembly 3 rotates under the drive of a power device such as a motor, driving the spur gear 38 to roll on the rack 33, so that the connecting seat 32 and the movable seat 21 move up and down along the drop tube 1. During the movement of the movable seat 21, the slider 26 inside it slides in the spiral groove 25 outside the drop tube 1, so that the movable seat 21 rotates while moving up and down. The rotating movable seat 21 drives the material bin 22 and the material head 1 231, the material head 232 and the material head 3 233 to rotate together, thereby achieving uniform material discharge at the bottom of the bin. Since the drop tube 1 is always full of material, the impact force of the material when it descends is greatly reduced, avoiding damage caused by impact and ensuring product quality. At the same time, during the rotation of the movable seat 21, the material at the bottom of the bin is stirred and mixed by the mixing assembly 4, ensuring the uniformity of the material distribution and avoiding the classification of materials with different characteristics.

[0031] like Figure 3 , Figure 4 and Fig. 9 As shown, the walking assembly 3 also includes an end gear 34 rotatably connected between the movable seat 21 and the connecting seat 32, and the outer side of the driving shaft 36 is fixedly connected with a bevel gear 37, and the bevel gear 37 and the end gear 34 are meshed with each other. A servo motor 35 is fixedly installed on the outer side of the connecting seat 32, and the output end of the driving shaft 36 is fixedly connected to one of the driving shafts 36 through a coupling. The top of the connecting seat 32 is fixedly connected with a collecting bucket 31, and the inside of the collecting bucket 31 is symmetrically fixedly connected with a sealing block. The movable seat 21, the diverter plate 24, the collecting bucket 31 and the connecting seat 32 are all on the same central axis.

[0032] When the embodiment of the present invention is actually applied, the servo motor 35 is started, driving the driving shaft 36 fixedly connected to it through the coupling to rotate, and the bevel gear 37 on the driving shaft 36 rotates accordingly and meshes with the end gear 34, so that the end gear 34 rotates, and the rotation of the end gear 34 drives the bevel gear 37 on the other driving shaft 36 to rotate, thereby realizing the synchronous rotation of the two driving shafts 36; when the driving shaft 36 rotates, the outer spur gear 38 rolls on the rack 33 symmetrically fixed inside the blanking tube 1, thereby driving the connecting seat 32 and the movable seat 21 connected thereto to move up and down along the blanking tube 1. During the movement, the collecting bucket 31 on the top of the connecting seat 32 collects the materials falling from above, and ensures that the materials will not fall from the collecting bucket 31 through the sealing block. The gap between the collecting bucket 31 and the dropping pipe 1 leaks; at the same time, since the movable seat 21, the diverter plate 24, the collecting bucket 31 and the connecting seat 32 are all on the same central axis, the entire device is more stable during operation and the flow of materials is smoother. The up and down movement and rotation of the movable seat 21, combined with the dropping bin 22 and the dropping head 1 231, the dropping head 232 and the dropping head 3 233 in the dropping assembly 2, realize the uniform dropping of materials at the bottom of the bin, and with the rotation of the movable seat 21, the material at the bottom of the bin can be stirred and mixed by the mixing assembly 4 to ensure the uniformity of the material distribution and avoid the grading of materials with different characteristics, thereby realizing the stable and uniform distribution of materials in the cylindrical silo and improving the storage efficiency and material quality of the cylindrical silo.

[0033] like Figures 5 to 8 As shown, the mixing component 4 includes a support block 41 uniformly fixedly connected to the outer side of the movable seat 21, the interior of the support block 41 is symmetrically fixedly connected with a mounting sleeve 46, the interior of the mounting sleeve 46 is rotatably connected with a mounting shaft 43, the bottom of the mounting shaft 43 is symmetrically fixedly connected with a stirring block 44, the outer side of the collecting bucket 31 is fixedly connected with a fixing plate 42, the bottom of the fixing plate 42 is provided with two annular grooves, the groove walls of the annular grooves are uniformly distributed with teeth, the top of the mounting shaft 43 is fixedly connected with a driving wheel 45, and the driving wheel 45 is meshed with the annular groove.

[0034] In actual application, as the movable seat 21 rotates, the support block 41 fixedly connected to the outer side thereof also rotates accordingly, and the mounting sleeve 46 inside the support block 41 provides support for the mounting shaft 43 and allows it to rotate therein. When the movable seat 21 drives the support block 41 to rotate, the driving wheel 45 on the top of the mounting shaft 43 engages with the teeth in the annular groove at the bottom of the fixed plate 42, so that the mounting shaft 43 can realize self-rotation while rotating with the movable seat 21; the stirring block 44 symmetrically fixedly connected to the bottom of the mounting shaft 43 stirs and mixes the materials at the bottom of the bin under the drive of the mounting shaft 43. Since the teeth are evenly distributed on the wall of the annular groove at the bottom of the fixed plate 42, the engagement of the driving wheel 45 with the annular groove can ensure that the rotation of the mounting shaft 43 is stable and uniform, so that the stirring block 44 stirs the materials more fully and evenly, which can effectively avoid the grading phenomenon of materials with different characteristics in the bin, ensure the uniformity of the distribution, and at the same time, through continuous stirring and mixing, it can promote air circulation between the materials, prevent local moisture or agglomeration, improve the storage stability of the materials, and reduce material loss and management costs.
