Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of silos, in particular to a silo breakage reduction device and a silo feeding method using the device. BACKGROUND

[0002] In the steel plate silo grain storage industry, especially in the corn deep processing industry, the raw grain will be severely broken when falling to the ground due to a large height difference during the warehousing process, which reduces the use rate of raw grain in the later production process.

[0003] The prior art mainly has the following problems:

[0004] 1. The breakage reduction device is placed in the silo, which affects the silo capacity;

[0005] 2. The breakage reduction device placed in the silo has a large concentrated load on the silo top at the moment of discharging after being buried in the raw grain;

[0006] 3. The breakage reduction device in the silo is prone to pipe sliding and blocking;

[0007] 4. The breakage reduction device in the silo is not easy to maintain. SUMMARY

[0008] The first object of the present application is to provide a silo breakage reduction device to solve the technical problems of the existing breakage reduction device placed in the silo, which affects the silo capacity, causes concentrated load on the silo at the moment of discharging, blocks, and is inconvenient to maintain.

[0009] To solve the above technical problems, the present application adopts the following technical scheme, a silo breakage reduction device, characterized by comprising:

[0010] A silo comprising a silo top and a silo wall;

[0011] A breakage reduction mechanism arranged outside the silo, comprising:

[0012] A feeding and distributing assembly arranged at the center of the silo top, the feeding and distributing assembly being provided with a feeding pipe, a central discharge port, and a side discharge port, the central discharge port and the side discharge port being switchable;

[0013] A material conveying assembly comprising a first material conveying pipe and a second material conveying pipe connected to each other, the first material conveying pipe being arranged outside the silo top, the first material conveying pipe being connected to the side discharge port of the distributing assembly, and the second material conveying pipe being arranged inside the silo.

[0014] This invention utilizes an externally mounted feeding and distribution assembly and a crushing reduction conveying assembly. The first conveying pipe of the conveying assembly passes through the silo roof and enters the silo through the second conveying pipe. This layered deceleration effectively reduces the breakage rate of the raw grain while maximizing the stability of the silo roof structure. The structure is simple and easy to maintain. This invention solves the problem of grain breakage during silo loading, ensures the stability of the silo roof structure, and facilitates regular maintenance and repair.

[0015] To address the technical problem of how to implement the feeding and distributing assembly, this invention adopts the following technical solution: the feeding and distributing assembly includes a distributing box, with a feeding pipe installed at the top of the distributing box; a central discharge port is installed at the bottom of the distributing box, and a gate is installed on the central discharge port; a side discharge port is installed on the side wall of the distributing box. This invention designs the feeding and distributing assembly as a distributing box, using a gate to switch between the central discharge port and the side discharge port. In the initial feeding stage, the side discharge port is used to discharge material, achieving feeding from all sides of the silo. The distance between the discharge port of the second conveying pipe and the bottom plate of the silo is utilized to reduce the breakage rate. In the later feeding stage, the central discharge port is opened, and the material enters the center of the silo through the central discharge port, completing the replenishment.

[0016] To address the issue that when raw grain enters the distribution box via the feed chute from the conveying equipment, the grain itself carries the initial velocity of the conveying equipment, causing uneven material distribution in the silo, this invention employs the following technical solution: a material equalization component is installed within the distribution assembly to evenly distribute the material to different side outlets, ensuring uniform grain feeding.

[0017] To address the technical problem of uneven material distribution during the feeding process in a crusher bin, which leads to uneven feeding, this invention adopts the following technical solution, wherein the material distribution component includes:

[0018] A material distribution box is mounted on the material distribution box via a connecting plate;

[0019] The material distribution cone is mounted on the material distribution box via an elastic suspension assembly, and the material distribution cone is located below the material distribution box; the material distribution cone can move linearly relative to the material distribution box to achieve the contact or separation between the sawing cone and the material distribution box;

[0020] Under the influence of gravity, the material distribution cone moves away from the material distribution box, and the material enters the distribution box evenly from the gap between the material distribution box and the material distribution cone.

[0021] When the raw grain in the equalization box is piled up to the specified height, that is, when the weight of the raw grain in the equalization box is greater than the set support force of the elastic component of the elastic hanging assembly, the uniformly distributed elastic component is compressed as a whole, causing the equalization cone to descend. Since the raw grain piled up in the equalization box itself forms a raw grain buffer layer, no matter how the upper grain is unbalanced, the lower raw grain flows evenly into the distribution box from the gap between the equalization cone and the equalization box due to the buffer layer effect.

[0022] To address the technical problem of how to implement a flexible suspension assembly, the present invention adopts the following technical solution: the flexible suspension assembly includes:

[0023] The first mounting plate is evenly distributed on the material distribution box;

[0024] The material distribution cone has two evenly distributed second mounting plates; the second mounting plates correspond to the first mounting plates; guide posts are provided on the first mounting plates and the second mounting plates, and limiting members are provided at both ends of the guide posts. Elastic members are provided on the guide posts on the upper second mounting plate, and sleeves are provided on the guide posts between the second mounting plates. The structure is simple and easy to assemble and disassemble.

[0025] To address the technical problem of material residue in the material distribution cone, this invention employs the following technical solution: a discharge hole is provided at the bottom of the material distribution cone. When the silo capacity reaches the design requirements, feeding is stopped, and the remaining material in the material distribution cone enters the silo through the discharge hole and the central discharge port, effectively preventing material residue.

[0026] To address the technical challenge of installing the feeding and distributing assembly on the silo roof, this invention employs the following solution: a silo roof disc is positioned at the center of the silo roof, a central support assembly is mounted on the silo roof disc, and the feeding and distributing assembly is mounted on the central support assembly. By utilizing the central support assembly to install the feeding and distributing assembly on the silo roof, both the structural stability of the silo roof and the sealing between the silo roof cover and the feeding and distributing assembly are ensured.

[0027] To solve the technical problem of how to install the first conveying pipe on the top of the silo, the present invention adopts the following technical solution, wherein the top of the silo includes rafters and a silo top cover plate installed on the rafters;

[0028] The upper part of the first conveying pipe is supported by a support beam assembly installed outside the silo top;

[0029] The lower part of the first conveying pipe is supported by a support assembly located outside the top of the bin.

[0030] The silo top cover is a conical plate, smaller at the top and larger at the bottom. Since the support requirements for the first conveying pipe are the same, a support beam assembly is used to support the first conveying pipe at the top of the silo top cover, and a support crossbeam assembly is set at the bottom of the silo top cover to support the first conveying pipe, ensuring consistent support strength.

[0031] To address the technical problem of how to implement the upper support beam assembly, the present invention adopts the following technical solution, wherein the upper support beam assembly comprises:

[0032] A support unit is disposed on the top cover plate above the rafters;

[0033] A crossbeam is provided on two opposing support units;

[0034] An upper support beam, the lower end of which is on the support crossbeam, and the upper end of which is mounted on the central support assembly;

[0035] The conveying pipe crossarm is positioned between the two upper support beams to support the upper part of the first conveying pipe.

[0036] To address the technical problem of how the support component is implemented, the present invention adopts the following technical solution, wherein the support component includes: a support unit disposed on the top cover plate above the rafters;

[0037] A feed pipe crossarm is positioned between the support units to support the lower part of the first feed pipe.

[0038] To address the technical problem of how to implement the support unit, the present invention adopts the following technical solution, wherein the support unit comprises:

[0039] Support legs are mounted on the top cover plate of the storage shed, which is located above the rafters; rainproof components are provided on the support legs;

[0040] A support plate is mounted on the support leg via the adjustment assembly, and the distance between the support plate and the support leg is adjustable; the support crossbeam is mounted on the support plate.

[0041] To solve the technical problem of how to connect the first and second conveying pipes, the present invention adopts the following technical solution: the first conveying pipe is connected to the second conveying pipe via a conveying pipe bend section and a conveying pipe transition section;

[0042] The elbow section of the conveying pipe passes through the corresponding silo cover plate and connects to the transition section of the conveying pipe inside the silo.

[0043] The transition section of the conveying pipe is designed to be inclined downwards and directed outwards from the silo, which further slows down the material flow.

[0044] To solve the technical problem of rainwater entering the silo through the bend of the conveying pipe, the present invention adopts the following technical solution: a through hole is provided on the silo cover plate, and a rainproof cover plate connector is provided on the through hole to prevent rainwater from entering the silo through the through hole.

[0045] To address the technical problem of how to implement the rainproof cover connector, the present invention adopts the following technical solution, wherein the rainproof cover connector includes:

[0046] A connecting ramp is installed on the bin cover plate;

[0047] The connecting pipe is vertically installed on the connecting inclined plate.

[0048] A rainproof component is installed on the upper part of the connecting pipe;

[0049] The vertical part of the conveying pipe bend passes through the through hole of the rainproof component, the connecting pipe, the connecting inclined plate, and the silo cover plate in sequence, and connects to the transition section of the conveying pipe inside the silo.

[0050] To solve the technical problem of the inconvenience of manually observing materials in silos and manually switching between the center discharge port and the side discharge port, the present invention adopts the following technical solution: a level gauge is installed on the silo wall to set the minimum material level height in the silo.

[0051] The silo also includes the controller, which is connected to the level gauge and the gate of the central discharge port.

[0052] The controller obtains the minimum material level height of the silo from the level gauge. When the raw grain in the silo exceeds the set height, the controller controls the electric gate at the bottom of the distribution box to open, and the raw grain enters the silo directly from the center for central replenishment feeding.

[0053] To further address the technical problem of reducing material flow rate and preventing breakage in the conveying assembly, the present invention adopts the following technical solution: a speed-reducing assembly is installed inside the second conveying pipe to reduce the flow rate of the material within the second conveying pipe.

[0054] To address the technical problem of how to implement the speed reduction component, the present invention adopts the following technical solution: the speed reduction component is a folding baffle, which has a simple structure and is easy to assemble and disassemble.

[0055] To address the technical problem of how to install the second conveying pipe, the present invention adopts the following technical solution: a bottom support assembly is provided at the bottom of the second conveying pipe, and the second conveying pipe is connected to the side plate of the bin wall via a back plate. The second conveying pipe is connected to the side plate of the bin wall via the back plate. The bottom of the second conveying pipe is reinforced by the bottom support assembly.

[0056] To address the technical problem of inconvenient installation of silo crushing devices, this invention adopts the following technical solution: the silo crushing device is a prefabricated structure. This invention features a fully prefabricated structure, facilitating assembly and disassembly.

[0057] A second objective of this invention is to provide a silo feeding method, which is achieved using the silo crushing device described in any of the above claims;

[0058] The feeding method is as follows:

[0059] The central discharge port of the feeding and distributing component is closed, and the raw grain pile enters the silo evenly through the side discharge port of the feeding and distributing component, via the first conveying pipe outside the silo and the second conveying pipe inside the silo, and is distributed around the silo to achieve the effect of slowing down crushing.

[0060] When the raw grain entering the silo reaches the designed height around the perimeter, the raw grain inside the silo presents a concave shape with higher edges and a lower center. At this time, the central outlet of the feeding and distributing component opens, and the raw grain enters the silo directly from the center through the central outlet of the feeding and distributing component, completing the final replenishment of the silo capacity.

[0075] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0076] Example 1

[0077] like Figure 1 As shown, the silo crushing device 10 is preferably an assembled structure. The silo crushing device 10 includes a silo 100 and a crushing mechanism.

[0078] The silo 100 includes the silo top 110 and the silo wall 120.

[0079] The silo roof 110 includes rafters 111. A silo roof cover 112 is mounted on the rafters 111. In one embodiment, a silo roof disc 113 is provided at the center of the silo roof 110, and a central support assembly 114 is provided on the silo roof disc 113.

[0080] In one embodiment, a level gauge is installed on the silo wall 120 to set the minimum material level height of the silo.

[0081] A crushing and lowering mechanism is installed on the silo 100. The crushing and lowering mechanism is located outside the silo 100. The crushing and lowering mechanism includes a feeding and distributing assembly 200 and a conveying assembly 300.

[0082] like Figure 1 As shown, the material conveying assembly 300 includes a first material conveying pipe 301 and a second material conveying pipe 302. In this embodiment, there are four first material conveying pipes 302, and the four first material conveying pipes 301 are evenly distributed around the outside of the silo top 110.

[0083] In one embodiment, the upper part of the first conveying pipe 301 is supported by an upper support beam assembly 310. The upper support beam assembly 310 is installed outside the silo top 110. Specifically, as shown... Figure 7 ... Figure 2 , Figure 3 , Figure 1As shown, the upper support beam assembly 310 includes a support unit 311, a support crossbeam 312, an upper support beam 313, and a conveying pipe crossbeam 314. The support unit 311 is mounted on the top cover plate above the rafters. The support crossbeam 312 is mounted on two opposing support units 311. The lower end of the upper support beam 313 is mounted on the support crossbeam 312, and the upper end of the upper support beam 313 is mounted on the central support assembly 114. The conveying pipe crossbeam 314 is mounted between the two upper support beams 313 to support the upper part of the first conveying pipe 301.

[0084] The lower part of the first conveying pipe 301 is supported by a support assembly 320. The support crossbeam assembly 320 is located outside the top of the bin. In one embodiment, such as Figure 6 , Figure 2 , Figure 3 , Figure 1 As shown, the support crossbeam assembly 320 includes a support unit 321 and a feed pipe crossbeam 322. The support unit 321 is mounted on the top cover plate above the rafters. The feed pipe crossbeam 322 is mounted on two opposing support units 321, and the support crossbeam 322 is used to support the lower part of the first feed pipe.

[0085] In one embodiment, such as Figure 8 As shown, support unit 311 and support unit 321 have the same structure, both including support leg 3111 and support plate 3113.

[0086] The outrigger 3111 is mounted on the top cover plate 112 above the rafter 111. In one embodiment, the outrigger 3111 is provided with a rainproof element 3112.

[0087] An adjusting assembly 3114 is mounted on the outrigger 3111. The adjusting assembly 3114 is preferably an adjusting stud or adjusting nut. A support plate 3113 is threaded onto the adjusting assembly 3114. The distance between the support plate and the outrigger is adjustable using the adjusting stud and adjusting nut. A second support crossbeam 322 is mounted on the support plate 3113.

[0088] The silo top cover is a conical plate, smaller at the top and larger at the bottom. Since the support requirements for the first conveying pipe are the same, a support beam assembly is used to support the first conveying pipe at the top of the silo top cover, and a support crossbeam assembly is set at the bottom of the silo top cover to support the first conveying pipe, ensuring consistent support strength.

[0089] like Figure 5As shown, in one embodiment, the first conveying pipe 301 is connected to the second conveying pipe 302 via a conveying pipe elbow section 303 and a conveying pipe transition section 304. The conveying pipe elbow section 303 passes through the corresponding silo cover plate 112 and connects to the conveying pipe transition section 304 inside the silo. A flange connection is established between the first conveying pipe 301 and the conveying pipe elbow section 303. A flange connection is established between the conveying pipe elbow section 303 and the conveying pipe transition section 304. The conveying pipe transition section 304 is flanged to the second conveying pipe 302.

[0090] Specifically, such as Figure 4 As shown, a through hole 1120 is provided on the silo cover plate 112 on which the first conveying pipe 301 is installed. The through hole 1120 can be used as a fan hole. A rainproof cover plate connector 330 is provided on the through hole 1120 to prevent rainwater from entering the silo through the through hole.

[0091] like Figure 5 As shown, in one embodiment, the rainproof cover connector 330 includes a connecting ramp 331, a connecting pipe 332, and a rainproof component 333.

[0092] A connecting ramp 331 is installed on the silo cover plate 112. A connecting pipe 332 is installed on the connecting ramp 331. A rainproof component 333 is installed on the upper part of the connecting pipe 332. Preferably, the rainproof component 333 has a rainproof skirt, which is welded to the upper part of the connecting pipe. The vertical part of the conveying pipe bend section 303 passes through the rainproof component 333, the connecting pipe 332, the connecting ramp 331, and the through hole 1120 of the silo top cover plate 120 in sequence, and connects to the conveying pipe transition section 304 inside the silo.

[0093] like Figure 1 As shown, the second conveying pipe 302 is located inside the silo. In one embodiment, a speed-reducing component is provided inside the second conveying pipe 302 to reduce the flow velocity of the material within the second conveying pipe. Preferably, the speed-reducing component is a deflector baffle. The deflector baffle slows down the material, thereby reducing breakage.

[0094] In one embodiment, such as Figure 1 As shown, a bottom support assembly 340 is provided at the bottom of the second conveying pipe 302, and the second conveying pipe 304 is connected to the side plate 1201 of the bin wall 120 through the back plate 350 of the conveying pipe.

[0095] like Figure 1 , Figure 9 As shown, the feeding and distributing assembly 200 is installed at the center of the silo top 110. Specifically, the feeding and distributing assembly 200 is installed on the central support assembly 114. By using the central support assembly to install the feeding and distributing assembly on the silo top, both the structural stability of the silo top and the sealing between the silo top cover and the feeding and distributing assembly are ensured.

[0096] The feeding and distributing assembly 200 is equipped with a feeding pipe 211, a central discharge port 212, and a side discharge port 213. The central discharge port 212 and the side discharge port 213 are switchable. The first conveying pipe 301 is connected to the side discharge port 203 of the distributing assembly 200.

[0097] Specifically, the feeding and distributing assembly 200 includes a distributing box 210, with a feeding pipe 211 at the top; a central discharge port 212 at the bottom of the distributing box 210, and a gate 214 on the central discharge port 212. Side discharge ports 213 are provided on the side wall of the distributing box 210. In this embodiment, there are four side discharge ports 213, evenly distributed on the side wall of the distributing box 210. Preferably, the side discharge ports 213 are inclined downwards relative to the distributing box 210.

[0098] In one embodiment, such as Figure 1 , Figure 9 As shown, the feeding and distributing assembly 200 is equipped with a material equalization assembly 220, which is used to evenly distribute the material to different side discharge ports. Specifically, the material equalization assembly 220 includes a material equalization box 221, a material equalization cone 222, and an elastic hanging assembly 223.

[0099] The material distribution box 221 is mounted on the material distribution box 210 via the connecting plate 215.

[0100] The material distribution cone 222 is mounted on the material distribution box 210 via the elastic hanging assembly 223, and the material distribution cone 222 is located below the material distribution box 210; the material distribution cone 222 can move linearly relative to the material distribution box 221 to achieve the contact or separation between the material distribution cone and the material distribution box; under the action of the material gravity, the material distribution cone moves away from the material distribution box, and the material enters the material distribution box evenly from the gap between the material distribution box and the material distribution cone.

[0101] In one embodiment, the elastic suspension assembly 223 includes a first mounting plate 2231, a second mounting plate 2232, a guide post 2233, and a limiting member 2234.

[0102] The first mounting plates 2231 are evenly distributed along the edge of the material distribution cone 222. The first mounting plates 2231 are set horizontally.

[0103] The second mounting plates 2232 are evenly distributed on the outer wall of the material distribution box 221. The second mounting plates 2232 are horizontally arranged. There are two second mounting plates 2232 in each group. The second mounting plates 2232 correspond to the first mounting plates 2231. Guide posts 2233 are provided on the first mounting plates 2231 and the second mounting plates 2231. Limiting elements 2234 are provided at the ends of the guide posts 2233. Elastic elements 2236 are provided on the guide posts 2233 on the upper second mounting plate 2232. Sleeves 2235 are provided on the guide posts between the second mounting plates.

[0104] The feeding and distributing assembly of this invention is installed on the top disc of the bin via a central support assembly. Its bottom is an electric gate and a uniform feeding device with four side outlets, which can self-correct material deviation.

[0105] In one embodiment, a discharge hole is provided at the bottom of the material distribution cone 222. When the silo capacity reaches the design requirements, feeding is stopped, and the remaining material in the material distribution cone enters the silo through the discharge hole and the central discharge port, effectively avoiding material residue.

[0106] This invention designs the feeding and distributing component as a distributing box, using a gate to switch between the central discharge port and the side discharge port on the distributing box. In the initial feeding stage, the side discharge port is used to discharge material, enabling material to be fed from all sides of the silo. The distance between the discharge port of the second conveying pipe and the bottom plate of the silo is used to reduce the breakage rate. In the later feeding stage, the central discharge port is opened, and the material enters the center of the silo through the central discharge port to complete the replenishment.

[0107] Working principle: Raw grain enters the distribution box through the feed pipe via the conveying equipment. At this time, the raw grain itself has its own initial velocity from the conveying equipment. Direct entry into the distribution box will cause uneven material distribution in the silo. The material distribution component consists of a material distribution box, elastic elements, guide columns, and material distribution cones. The design is that when the raw grain in the material distribution box accumulates to a specified height (i.e., the weight of the raw grain in the material distribution box is greater than the set support force of the elastic elements), the evenly distributed elastic elements are compressed as a whole, causing the material distribution cone to descend. Since the raw grain accumulated in the material distribution box itself forms a raw grain buffer layer, no matter how unevenly the upper grain is loaded, the lower grain flows evenly into the distribution box from the gap between the material distribution box and the material distribution cone due to the buffer layer.

[0108] In one embodiment, the silo further includes a controller, which is connected to a level gauge and a gate 214 at the central discharge port. The controller obtains the minimum material level height of the silo from the level gauge. When the raw grain in the silo exceeds the set height, the controller controls the electric gate at the bottom of the distribution box to open, allowing the raw grain to enter the silo directly from the center for central replenishment feeding.

[0109] Raw grain enters the distribution box through the feed pipe. The silo wall level gauge is set with a minimum material level. When the raw grain in the silo has not reached the set height, the bottom gate of the distribution box closes, and the raw grain flows evenly from the four side outlets along the first conveyor pipe (supported by an upper support beam, inclined chute crossbeam, and support assembly via a cover plate on the rafters at the upper end, and by an inclined chute crossbeam and support assembly via a cover plate on the lower end) towards the surrounding silo walls. The tail end passes through the cover plate via a bend in the conveyor pipe and connects to the second conveyor pipe via a transition section. The second conveyor pipe has a deflector baffle to slow down the material and reduce breakage. The second conveyor pipe is connected to the side plate of the silo wall via a back plate. The bottom of the second conveyor pipe is reinforced by a bottom support.

[0110] Once the grain level in the silo exceeds the set height, the electric gate at the bottom of the distribution box opens, allowing the grain to enter the silo directly from the center for central replenishment. The entire device is fully assembled, solving the problem of grain breakage during silo entry, ensuring the stability of the silo roof structure, and facilitating regular maintenance and repair.

[0111] This invention utilizes an externally mounted feeding and distribution assembly and a crushing reduction conveying assembly. The first conveying pipe of the conveying assembly passes through the silo roof and enters the silo through the second conveying pipe. This layered deceleration effectively reduces the breakage rate of the raw grain while maximizing the stability of the silo roof structure. The structure is simple and easy to maintain. This invention solves the problem of grain breakage during silo loading, ensures the stability of the silo roof structure, and facilitates regular maintenance and repair.

[0112] Example 2

[0113] The silo feeding method is implemented using any one of the silo crushing devices in Example 1; the feeding method is as follows:

[0114] The central discharge port of the feeding and distributing component is closed, and the raw grain pile enters the silo evenly through the side discharge port of the feeding and distributing component, via the first conveying pipe outside the silo and the second conveying pipe inside the silo, and is distributed around the silo to achieve the effect of slowing down crushing.

[0115] When the raw grain entering the silo reaches the designed height around the perimeter, the raw grain inside the silo presents a concave shape with higher edges and a lower center. At this time, the central outlet of the feeding and distributing component opens, and the raw grain enters the silo directly from the center through the central outlet of the feeding and distributing component, completing the final replenishment of the silo capacity.

[0116] The grain feeding process is divided into two stages. In the first stage (crush reduction stage), when the gate at the central discharge outlet is closed, the raw grain is fed into the silo evenly from all sides, achieving a slow and gradual reduction of crushing. In the second stage (filling the silo), when the raw grain fed into the silo from all sides reaches its maximum height, the raw grain inside the silo presents a concave shape with higher edges and a lower center. At this time, the gate at the central discharge outlet is opened, and the raw grain is fed directly into the silo from the center through the central discharge outlet, completing the final filling of the silo.

[0117] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Furthermore, the contents not described in detail in this specification are all prior art known to those skilled in the art.
