Description

Technical Field

[0001] This utility model belongs to the field of bulk grain storage technology, specifically relating to a cleaning component. This utility model also relates to a cleaning mechanism, including the aforementioned cleaning component. Furthermore, this utility model relates to a cleaning device, including the aforementioned cleaning mechanism. Background Technology

[0002] There are generally two unloading methods for large cylindrical silos: conical silo bottom, which uses the material to flow by gravity to complete the unloading; and horizontal silo bottom, where some material will remain after a large amount of material is unloaded by gravity, and the material will be cleaned manually or mechanically.

[0003] Because conical-bottom silos require higher construction costs, most existing silos, especially large silos, are flat-bottom silos. The cleaning of residual material generally involves two methods: manual cleaning or cleaning machines. Cleaning machines offer higher efficiency and lower cleaning costs, and most existing cleaning machines use an auger structure. Auger structures are simple, require less maintenance, are reliable, and are widely used. However, they also have limitations in maximum output, residual material buildup, and poor ground adaptability. Because the auger's main shaft is a rigid structure, it cannot be well matched to the silo floor. Furthermore, to ensure the auger's normal operation is not affected by uneven ground, a certain height must be left under the auger. Therefore, auger-type cleaning machines typically leave a 40-60mm residual material layer after operation, requiring manual cleaning.

[0004] The main solution for residue issues in auger-type silo cleaning machines, both domestically and internationally, is to add a cleaning brush structure to the back of the auger casing. This reduces the amount of residual material after cleaning to about 10-15mm, but a significant amount remains. Furthermore, in some cases, adding the cleaning brush can greatly increase the operating resistance of the cleaning machine, causing it to malfunction. Additionally, the bottom of the silo is often made of concrete, which has some flatness deviation, further increasing the amount of residue.

[0005] In most applications, the same silo is often used to store different materials. Therefore, when changing the type of material, the remaining material always needs to be cleaned manually. Taking an 8000T silo as an example, after the auger cleaning machine completes the cleaning work, there will generally be 7T-12T of material left on the ground. At this time, it takes 3-4 people 5-6 days to complete the final cleaning. Moreover, the cleaning work is carried out in a semi-enclosed environment with a lot of dust, which is inconvenient to enter. Internal combustion machinery or power tools cannot be used. The cleaning work is huge and the environment is harsh. Utility Model Content

[0006] The first objective of this invention is to provide a cleaning component to solve the technical problem of material residue in existing screw conveyor cleaning systems.

[0007] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a clearance component, characterized in that it includes: A ring conveyor chain, wherein connecting components are spaced apart on the ring conveyor chain, and the connecting components include connecting plates disposed on both sides of the ring conveyor chain; Cleaning scrapers are spaced apart on the annular conveyor chain; the cleaning scrapers are provided with annular conveyor chain mounting grooves; The annular conveyor chain is located in the annular conveyor chain mounting groove, and the connecting plate is detachably connected to the cleaning scraper on one side of the corresponding annular conveyor chain mounting groove.

[0008] This utility model's cleaning component features a semi-flexible traction structure, allowing for a certain degree of sag. It can fit well even on slightly uneven ground, exhibiting high terrain adaptability and significantly reducing residue. The cleaning scraper of this utility model's cleaning component does not cause strong material overturning during conveying, thus its energy utilization efficiency is far higher than that of an auger, and its operating power is low.

[0009] A further improvement to this utility model is that the cleaning scraper and the annular conveyor chain are arranged perpendicularly.

[0010] A further improvement to this utility model is made in that the cleaning scraper is inclined relative to the annular conveyor chain.

[0011] A further improvement to this utility model is made: the outer side of the cleaning scraper on one side of the mounting groove of the annular conveyor chain is inclined relative to its inner side to form a pushing part.

[0012] To address the issues of easy wear and high resistance in the contact area between the scraper and the ground, the end of the cleaning scraper is made of a wear-resistant soft material, such as rubber. The end of the cleaning scraper is the part that contacts the ground, and the use of a wear-resistant soft material avoids jamming and damage caused by contact with hard protrusions on the ground.

[0013] A further improvement to this utility model is made to the fact that the height of the mounting groove of the annular conveyor chain is greater than its width; The height of the annular conveyor chain mounting groove is greater than half the height of the cleaning scraper; the annular conveyor chain mounting groove is aligned with the vertical center line of the cleaning scraper.

[0014] A further improvement to this utility model is made: the bottom of the annular conveyor chain is higher than the bottom of the annular conveyor chain mounting groove; the annular conveyor chain is arranged to coincide with the transverse center line of the cleaning scraper.

[0015] The second objective of this utility model is to provide a cleaning mechanism, characterized by comprising a cleaning housing, and a head sprocket assembly and a tail sprocket assembly disposed within the cleaning housing, wherein the head sprocket assembly and the tail sprocket assembly are provided with the cleaning components described in any of the above-mentioned embodiments. A circular conveyor chain performs a circular motion around the head and tail sprocket assemblies, driving a cleaning scraper fixed on the circular conveyor chain to move and pushing the material entering the cleaning machine towards the center of the storage chamber. The third objective of this utility model is to provide a warehouse clearing device, characterized in that it includes: The aforementioned clearing-out organizations; A central positioning mechanism is located at the head of the clearing mechanism; A walking drive mechanism is located at the rear of the clearing mechanism; The walking support mechanism is spaced out in the middle of the clearing mechanism.

[0016] The walking drive mechanism drives the cleaning mechanism to rotate around the central positioning mechanism, and the main body of the cleaning mechanism is supported by the walking support mechanism; the circular conveyor chain makes a circular motion around the head and tail sprocket assembly, which drives the cleaning scraper fixed on the circular conveyor chain to move and push the material entering the cleaning machine towards the center of the warehouse, and then discharges it out of the warehouse through the hopper in the center of the warehouse, thus completing the cleaning action.

[0017] To solve the problem of material re-carrying, this utility model adopts the following technical solution: a partition is installed inside the cleaning shell, dividing the cleaning shell into an upper shell and a lower shell. The upper shell is a closed structure, and the lower shell is a semi-open structure. The partition also supports the upper chain of the annular conveyor chain. The closed structure of the upper shell ensures that the upper chain does not come into contact with the material, avoiding material re-carrying and excessive operating resistance of the equipment.

[0018] To address the technical problem of materials being pushed away upon entering the cleaning mechanism, this invention adopts the following technical solution: The cleaning shell includes a top plate, a first side plate, and a second side plate. The bottom of the second side plate, where the lower shell is located, is higher than the bottom of the first side plate, creating a semi-open structure for the lower shell. The first side plate is located on the back side, and the second side plate is located on the front side. The second side plate has a higher reserved space on one side for the material flow channel into the cleaning machine, while the first side plate has a lower reserved height to prevent materials entering the cleaning machine from being pushed away.

[0019] To avoid the technical problems of excessive pressure, deformation, and material leakage on the first side plate caused by the scraper pushing the material towards the center of the silo, a pushing part is inclinedly provided on the silo cleaning scraper near the first side plate. The pushing part faces the center positioning mechanism and is used to prevent the material from squeezing the first side plate and causing it to deform.

[0020] To solve the technical problem of the power source for the clearing mechanism, the present invention adopts the following technical solution: the clearing mechanism further includes a power unit, which drives and connects to the head sprocket assembly.

[0021] To address the technical problem of chain slack after use, this utility model adopts the following technical solution: the clearing mechanism further includes a chain tensioning mechanism to tension the head sprocket assembly and ensure stable chain operation.

[0022] To solve the technical problem of unstable ground contact of the walking drive mechanism, the present invention adopts the following technical solution: the walking drive mechanism and the clearing mechanism are hinged to ensure good ground contact of the walking drive mechanism.

Detailed Implementation

[0024] The present invention will be further described below with reference to the figures.

[0025] Existing screed conveying machines use auger conveying components, which have the following technical problems: The auger causes strong tumbling of materials during conveying, resulting in low energy utilization efficiency. When the auger rotates at high speed, it propels materials in all directions, causing severe material breakage. The auger shaft is a rigid structure, and it must be aligned during installation and commissioning; otherwise, excessive shaft deflection or even shaft breakage can easily occur.

[0026] Example 1 like Figures 1-4 As shown, this embodiment provides a cleaning assembly 140, including an annular conveyor chain 141 and a cleaning scraper 142. The cleaning scraper 142 is arranged perpendicularly to the annular conveyor chain 141.

[0027] Connecting components 143 are spaced apart on the annular conveyor chain 141. Specifically, the connecting components 143 include a first connecting plate 1431 and a second connecting plate 1432 disposed on both sides of the annular conveyor chain 141. Preferably, the first connecting plate 1431 is perpendicular to the annular conveyor chain 141. Preferably, the second connecting plate 1432 is perpendicular to the annular conveyor chain 141. A first connecting hole is machined on the first connecting plate 1431. A first connecting hole is machined on the second connecting plate 1432.

[0028] The annular conveyor chain 141 has spaced cleaning scrapers 142. The cleaning scrapers 142 are provided with annular conveyor chain mounting grooves 1420.

[0029] In one embodiment, the height of the annular conveyor chain mounting groove 14 is greater than its width; the height of the annular conveyor chain mounting groove 1420 is greater than half the height of the cleaning scraper 142.

[0030] In one embodiment, the annular conveyor chain mounting groove 4120 is aligned with the vertical center line of the cleaning scraper 142.

[0031] In one embodiment, the cleaning scrapers 142 on both sides of the annular conveyor chain mounting groove 1420 form a scraper connecting part one 1421 and a scraper connecting part two 1422. A connecting hole two is machined on the scraper connecting part one 1421. A connecting hole two is machined on the scraper connecting part two 1422. The cleaning scraper 142 at the bottom of the annular conveyor chain mounting groove 1420 forms a scraping part 1423.

[0032] The annular conveyor chain 141 is located in the annular conveyor chain mounting groove 1420. A connector 144 is installed in the first connecting hole of the connecting plate 1431 and the second connecting hole of the scraper connecting part 1421 to achieve the connection between the two. A connector 144 is installed in the first connecting hole of the connecting plate 1432 and the second connecting hole of the scraper connecting part 1422 to achieve the connection between the two, thereby realizing the connection between the annular conveyor chain 141 and the cleaning scraper 142.

[0033] In one embodiment, the bottom of the annular conveyor chain 141 is higher than the bottom of the annular conveyor chain mounting groove 1420.

[0034] In one embodiment, the annular conveyor chain 141 is arranged to coincide with the transverse centerline of the cleaning scraper 142.

[0035] To address the issues of easy wear and high resistance in the contact area between the scraper and the ground, the end of the cleaning scraper 142 is made of a wear-resistant soft material, such as rubber. The end of the cleaning scraper is the part that contacts the ground, and the use of a wear-resistant soft material avoids jamming and damage caused by contact with hard protrusions on the ground.

[0036] Example 2 like Figures 5-8 As shown, this embodiment provides a cleaning assembly 140, including a ring conveyor chain 141 and a cleaning scraper 142. Unlike Embodiment 1, the cleaning scraper 142 is inclined relative to the ring conveyor chain 141. Figure 7 As shown, the angle between the cleaning scraper 142 and the annular conveyor chain 141 is A. A is preferably an acute angle.

[0037] Connecting assemblies 143 are spaced apart on the annular conveyor chain 141. Specifically, the connecting assemblies 143 include a first connecting plate 1431 and a second connecting plate 1432 disposed on both sides of the annular conveyor chain 141. The first connecting plate 1431 is inclined relative to the annular conveyor chain 141.

[0038] Example 3 like Figures 9-12As shown, this embodiment provides a cleaning assembly 140, including an annular conveyor chain 141 and a cleaning scraper 142. Unlike Embodiment 1, the outer side of the cleaning scraper 142 on one side of the annular conveyor chain mounting groove 1420 is inclined relative to its inner side, forming a pushing part 145. The pushing part 145 can be formed by directly bending the cleaning scraper 142, or it can be welded onto the cleaning scraper 142.

[0039] Example 4 like Figures 13-16 As shown, the clearing mechanism 100 includes a clearing housing 110, a head sprocket assembly 120, a tail sprocket assembly 130, and any one of the clearing components 140 in Embodiment 1.

[0040] The clearing shell 110 includes a top plate 111, a first side plate 112, a second side plate 113, a first end plate 114, and a second end plate 115.

[0041] In one embodiment, a partition 116 is provided inside the cleaning housing 110, dividing the cleaning housing into upper and lower layers, specifically including an upper housing 117 and a lower housing 118. The upper housing 117 is a closed structure to ensure that the upper chain does not come into contact with the material, thereby preventing material backflow and excessive resistance during equipment operation.

[0042] In one embodiment, the second side plate 113 is located on the receiving side, and the first side plate 112 is located on the back side. The bottom of the second side plate 113, where the lower housing 118 is located, is higher than the bottom of the first side plate 112, making the lower housing 118 a semi-open structure. The lower layer of the lower housing 118 has a semi-open structure, with one side of the second side plate having a higher reserved space for the material flow channel into the cleaning machine, while the other side of the first side plate has a lower reserved height to prevent the material entering the cleaning machine from being pushed away.

[0043] The head of the cleaning housing 110 is fitted with a head sprocket assembly 120 via a bearing assembly 170. The head sprocket assembly 120 includes a head sprocket and a head sprocket shaft. The tail of the cleaning housing 110 is fitted with a tail sprocket assembly 130 via a bearing assembly 170. The tail sprocket assembly 130 includes a tail sprocket and a tail sprocket shaft. A cleaning assembly 140 is fitted onto the head sprocket assembly 120 and the tail sprocket assembly 130.

[0044] The partition 111 also supports the upper chain of the annular conveyor chain. The upper cleaning assembly is supported by the partition, and the lower cleaning scraper is in direct contact with the ground. This invention results in low material residue because the cleaning scraper remains in constant contact with the ground during operation, ensuring that the vast majority of the material is carried away by the cleaning scraper.

[0045] To prevent the rigid shell from rubbing against the ground, the lower part of the first side plate can be made of flexible materials.

[0046] In one embodiment, the clearing mechanism 100 further includes a power unit 150 that drives the head sprocket assembly 120.

[0047] In one embodiment, the clearing mechanism 100 further includes a chain tensioning mechanism 160, which uses the tensioning head sprocket assembly 120 to ensure stable chain operation.

[0048] Example 5 like Figures 13-16 As shown, the clearing machine 10 includes a clearing mechanism 100, a center positioning mechanism 200, a walking drive mechanism 300, and a walking support mechanism 400, according to any of Embodiment 2. The center positioning mechanism 200 is installed at the head of the clearing mechanism 100. The walking drive mechanism 300 is installed at the tail of the clearing mechanism 100. Specifically, the walking drive mechanism 300 is hinged to the clearing mechanism 100 to ensure good ground contact. The walking support mechanisms 400 are spaced apart along the length of the clearing mechanism and are mounted on the clearing mechanism 100.

[0049] To avoid the technical problems of excessive pressure, deformation, and material leakage on the first side plate caused by the scraper pushing the material towards the center of the silo, a pushing part 145 is inclinedly provided on the silo cleaning scraper 142 near the first side plate 112. The pushing part 145 faces the center positioning mechanism 200 and is used to prevent the material from squeezing and deforming the first side plate. The pushing part 145 can be formed by directly bending the silo cleaning scraper 142 or welded to the silo cleaning scraper 142.

[0050] During operation, the walking drive mechanism drives the cleaning mechanism to rotate around the central positioning mechanism, and the main body of the cleaning mechanism is supported by the walking support mechanism; the annular conveyor chain makes an annular motion around the head and tail sprocket assembly, which drives the cleaning scraper fixed on the annular conveyor chain to move and push the material entering the cleaning machine toward the center of the bin, and then discharges it out of the bin through the hopper in the center of the bin, thus completing the cleaning action.

[0051] The cleaning scraper of this utility model does not cause strong tumbling of materials during the conveying process, so its energy utilization efficiency is much higher than that of the screw conveyor and its operating power is low.

[0052] This utility model of the clearing component greatly reduces the high-speed throwing and impact of materials in all directions, resulting in less material breakage.

[0053] This utility model's clearance component is a semi-flexible traction structure, allowing for a certain degree of sagging. It can fit well even on slightly uneven ground, exhibiting high terrain adaptability.

[0054] This utility model has low installation and debugging requirements.

[0055] The above embodiments are only for illustrating the technical features and concept of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made according to the spirit and implementation of this utility model should be covered within the protection scope of this utility model.
