Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, and more specifically, it relates to a feed feeding and unloading platform. Background Technology

[0002] Feed mills mostly use corn and soybeans as their main raw materials. The feeding and unloading of these raw materials has a significant impact on the entire feed production process. Feed raw materials are mostly transported to the site by truck for unloading. After arrival, dump trucks directly dump the raw materials onto an unloading platform on the ground. The raw materials first pass through a feeding grid on the unloading platform into an underground guide silo, and then are transferred to various storage silos. During unloading, some dust and raw materials adhere to the feeding grid during this feeding method. Since existing feeding grids are all integrated and fixed to the ground, manual cleaning is required from time to time to prevent the adhered raw materials and dust from deteriorating and contaminating subsequent raw materials. This is not only difficult and ineffective to clean, but also leads to waste of raw materials and blockage of the feeding grid in the long run. The feeding efficiency of the platform is affected, and the overall feed production cost is increased. When the feeding grid is damaged, it often needs to be replaced entirely. If it is not repaired and replaced in time, it will affect the overall load-bearing strength of the feeding grid, thus affecting the feeding efficiency. This results in problems such as inconvenient maintenance and cleaning, low feeding efficiency, and high overall production costs. In addition, since the feeding grid is generally set to be flush with the ground at the unloading point, the existing unloading platform does not have a structure to block and protect the feeding grid. This makes it very easy for rainwater, dust, other debris, or rodents to enter the feed hopper or block the feeding grid, resulting in raw material loss and affecting the feeding efficiency, which increases the overall feed production cost. Overall, the platform suffers from problems such as inconvenient maintenance and cleaning, low feeding efficiency, and high overall production costs. Utility Model Content

The filter column is V-shaped. The two open ends and the closed ends of the filter column are respectively connected to the adjacent reinforcing ribs. The longitudinal beams are located between adjacent filter columns.

[0008] Further configuration: Above the middle reinforcing crossbar, there is a middle pressure plate that presses the fixing frame down onto the upper end of the middle reinforcing crossbar. The two ends of the middle pressure plate are connected to the two sides of the outer frame by hand-tightened bolts.

[0009] Further configuration: The cleaning assembly includes a connecting plate, a scraper, a cleaning roller, and an air blowing assembly for blowing residual materials on the filter plate and mesh plate into the underground hopper. From back to front, the bottom of the connecting plate is sequentially connected to the air blowing assembly, an electric push rod, and a rotating frame arranged in an inverted U-shape. The two ends of the cleaning roller are rotatably connected to the two open ends of the rotating frame. The two ends of the cleaning roller are provided with rolling parts for rolling on the side pressure plate. A soft brush is connected to the circumference of the cleaning roller. The bottom end of the scraper has a clearance hole for the crossbeam to pass through. The top rod of the electric push rod is fixedly connected to the top end of the scraper. The driving mechanism includes a set of long slide rails located on the other two sides of the outer frame and a linear guide rail mounted on one of the long slide rails. One end of the connecting plate is fixedly connected to the slider of the linear guide rail, and the other end of the connecting plate is slidably connected to the other long slide rail. A photoelectric switch for detecting the electric push rod is provided on one side of the long slide rail, and the photoelectric switch is located above one side of the mesh plate.

[0010] Further configuration: The grid plate is provided with a rotating motor on both sides to drive the long slide rail to rotate up and down by 90°.

[0014] In summary, this utility model, by designing the mesh plate with its lower end mounted on the ground and its upper end protruding above the ground, prevents rainwater or other debris from flowing from the ground through the mesh plate into the underground hopper, thus avoiding raw material loss and affecting feeding efficiency. This improves feeding efficiency and reduces overall production costs. The grooves, side pressure plates, and several filter plates increase the overall strength and load-bearing capacity of the mesh plate. When replacement or cleaning is needed, simply unscrew the bolts, remove the side pressure plates, and replace the corresponding filter plates. This further reduces overall production costs and allows for easy removal and replacement of the filter plates. The waterproof cloth, hooks, hanging rings, and automatic winding mechanism further enhance the design. When unloading is not required, the waterproof cloth is pulled out from the automatic winding mechanism to completely cover the upper surface of the filter plate, and then hooked onto the hanging ring using the barbs. When unloading, simply remove the barbs from the hanging ring, and the automatic winding mechanism will automatically roll up the waterproof cloth, thus achieving the functions of covering the filter plate and automatically winding the waterproof cloth. The cleaning component and drive mechanism sweep the residual new raw material on the upper surface of the filter plate or the mesh plate into the underground hopper, which plays a role in automatically cleaning the filter plate or the mesh plate. The dust removal device is used to absorb the dust raised during the unloading process, so as to avoid clogging of the mesh plate and filter plate and affecting the feeding efficiency, thereby further improving the overall feeding efficiency.

[0015] This utility model integrates the functions of automatic cleaning, automatic dust removal, detachable filter plate and mesh plate, and filter plate shielding, making it easy to disassemble, clean or repair and replace, preventing feed blockage and reducing production cost waste; it has the advantages of easy maintenance and cleaning, high feed efficiency and reduced production cost.

[0026] To explain the technical content, objectives, and effects of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. It should be noted that the terms "upper" and "lower" used in the following description refer to the attached drawings. Figure 1 and Figure 4 The direction in the middle, the words "bottom" and "top" refer to the attached Figure 1 and Figure 4 The direction towards the geometric center of a specific component.

[0027] Please refer to Figures 1 to 9As shown, a feed feeding and unloading platform includes a filter plate, a grid plate 1 with its lower end embedded in the ground, an underground hopper 2 installed below the grid plate 1, and dust collection devices located above both sides of the grid plate 1. The upper end of the grid plate 1 protrudes from the ground, and a groove 3 is provided on the upper surface for placing the filter plate. The upper surfaces of the other two sides of the grid plate 1 are provided with side pressure plates 4 for pressing and locking the filter plate into the groove 3. The two ends of the side pressure plates 4 are connected to the two sides of the grid plate 1 by bolts. The filter plate includes a fixing frame 5 and several filter columns 6. Adjacent filter columns The filters 6 are interconnected in a mesh pattern and are all fixedly connected within the fixed frame 5. Each filter column 6 is located above each mesh hole of the mesh plate 1. A waterproof cloth 7 for covering the filter plate and an automatic winding mechanism for driving the waterproof cloth 7 to roll up are provided on one side of the mesh plate 1. A hanging ring 8 is provided on the other side of the mesh plate 1. The two ends of the waterproof cloth 7 are connected to barbs 9 that are hung on the hanging ring 8. Cleaning components for cleaning the filter plate and the upper surface of the mesh plate 1 are provided on both sides of the mesh plate 1. The cleaning components are connected to a driving mechanism that drives them to move along the line connecting the two sides of the mesh plate 1.

[0028] As described above, by positioning the mesh plate 1 with its lower end facing forward onto the ground and its upper end protruding above the ground, rainwater or other debris is prevented from flowing from the ground through the mesh plate 1 into the underground hopper 2, thus avoiding raw material loss and affecting feeding efficiency. This reduces waste of raw materials in overall feed production, improving feeding efficiency and lowering overall production costs. The grooves 3 and several filter plates increase the overall strength and load-bearing capacity of the mesh plate 1, reducing the likelihood of damage. Furthermore, since the filter plates are located at the top of the mesh plate 1, they are the first to fail. When replacement is needed, only the corresponding filter plate needs to be replaced, reducing maintenance and replacement costs and further lowering overall production costs. When it is necessary to disassemble, clean, or replace the filter plate, simply unscrew the bolts at both ends of the side pressure plate 4, remove the side pressure plate 4 from the filter plate, and take out the corresponding filter plate for cleaning or replacement. After cleaning and drying or after repair and replacement, first put the cleaned or repaired filter plate back into the groove 3, then move the side pressure plate 4 to press the filter plate down and lock it in the groove 3, and then tighten the bolts at both ends of the pressure plate. This achieves the function of disassembling, cleaning, or replacing the filter plate. By setting each filter column 6 of the filter plate above each mesh hole of the grid plate 1, small animals such as mice are prevented from entering the hopper and causing raw material loss, which further reduces the overall production cost.

[0029] Using the waterproof cloth 7, hooks 9, hanging rings 8, and an automatic winding mechanism, when unloading is not required, the waterproof cloth 7 is pulled out from the automatic winding mechanism until it completely covers the upper surface of the filter plate. Then, the hooks 9 are hooked onto the hanging rings 8. When unloading is required, simply remove the hooks 9 from the hanging rings 8, and the automatic winding mechanism will automatically wind up the waterproof cloth 7, thus achieving the functions of covering the filter plate and automatically winding up the waterproof cloth 7. When the filter plate needs to be cleaned after unloading the raw material, the cleaning component and drive mechanism are activated. The drive mechanism is activated to move the cleaning component along the mesh. The line connecting both sides of plate 1 is moved horizontally, and the residual new material on the upper surface of the filter plate is swept into the underground hopper 2. After the filter plates are disassembled and cleaned, when the mesh plate 1 needs to be cleaned, the cleaning component is used to sweep the residual new material on the upper surface of the mesh plate 1 into the underground hopper 2 along the line connecting both sides of the mesh plate 1, which plays a role in automatically cleaning the filter plate or mesh plate 1. The dust removal device is used to absorb the dust raised during the unloading process, so as to avoid excessive dust raising that will cause the mesh plate 1 and filter plate to be blocked, thus affecting the feeding efficiency and further improving the overall feeding efficiency.

[0030] Furthermore, the automatic winding mechanism includes a fixed cylinder 10, a roll 11 fitted inside the fixed cylinder 10, a U-shaped bracket 12, and a spring 14 fitted on the roll 11. The two ends of the fixed cylinder 10 are fixedly connected to the two open ends of the bracket 12. The bracket 12 is installed on one side of the grid plate 1. The two ends of the roll 11 are rotatably connected to the two open ends of the bracket 12. One end of the spring 14 is fixedly connected to the roll 11, and the other end of the spring 14 is fixedly connected to one end of the waterproof cloth 7. A limiting opening 15 is provided on the side of the fixed cylinder 10 near the grid plate 1 for the other end of the waterproof cloth 7 to pass through. The other end of the waterproof cloth 7 is connected to a baffle 16.

[0031] As described above, when it is necessary to open the waterproof cloth 7, by using the fixed cylinder 10, the roll 11, the baffle 16, the bracket 12, and the spring 14, one only needs to grab the baffle 16 to grab the other end of the waterproof cloth 7 and pull the waterproof cloth 7 out from the limiting port 15 until the waterproof cloth 7 completely covers the upper surface of the filter plate. Then, the barb 9 is hung on the hanging ring 8 to achieve the function of blocking the filter plate. When it is necessary to unload the material, one only needs to remove the barb 9 from the hanging ring 8. Under the elastic force of the spring 14, the waterproof cloth 7 rotates and rolls up with the fixed cylinder 10, thus achieving the function of automatically rolling up the waterproof cloth 7.

[0032] Furthermore, the grid plate 1 includes an outer frame 17, several longitudinal beams 18 and several transverse beams 19 fixed within the outer frame 17. The longitudinal beams 18 are cylindrical. A middle reinforcing crossbar 20 for placing the fixing frame 5 is connected between the two sides of the outer frame 17. Several reinforcing longitudinal bars 21 are evenly connected between the other two sides of the outer frame 17. The transverse beams 19 and longitudinal beams 18 are interconnected to form a grid. The inner side of the outer frame 17 is provided with a clearance groove 22 for placing the fixing frame 5. Magnets 23 are connected to the upper surfaces of opposite sides of the outer frame 17. The waterproof cloth 7 is connected with iron sheets 24 that are magnetically connected to the magnets 23. Several reinforcing ribs 25 located above the transverse beams 19 are evenly connected within the fixing frame 5. The filter column 6 is V-shaped. The two open ends and the closed ends of the filter column 6 are respectively connected to the adjacent reinforcing ribs 25. The longitudinal beams 18 are located between adjacent filter columns 6.

[0033] As can be seen from the above description, by setting the filter column 6 in a V-shape, with the two open ends and the closed ends of the filter column 6 connected to the adjacent reinforcing ribs 25 respectively, it can be seen that the cross-sectional area of ​​the mesh of the grid plate 1 is set to be larger than the cross-sectional area of ​​the filter holes of the filter plate. This setting is to prevent rats and other animals from entering the underground hopper 2, and also to facilitate the cleaning of the grid plate 1. The overall strength and load-bearing capacity of the grid plate 1 are improved by the intermediate reinforcing crossbar 20 and reinforcing longitudinal bar 21. The overall strength and load-bearing capacity of the filter plate are improved by the reinforcing ribs 25. When the waterproof cloth 7 is covered on the filter plate, the attraction between the magnet 23 and the iron block further ensures that the waterproof cloth 7 is tightly covered on the filter plate.

[0034] Furthermore, an intermediate pressure plate 26 is provided above the intermediate reinforcing crossbar 20 to press the fixing frame 5 down onto the upper end of the intermediate reinforcing crossbar 20. The two ends of the intermediate pressure plate 26 are connected to the two sides of the outer frame 17 by hand-tightening bolts. A long strip hole 27 is provided in the middle of the waterproof cloth 7 for the intermediate pressure plate 26 to pass through.

[0035] As described above, the intermediate pressure plate 26 is used to press the fixed frame 5 down onto the upper end of the intermediate reinforcing crossbar 20. At the same time, it prevents raw materials and dust from entering the gap between adjacent filter plates, thereby improving the installation stability of the filter plates and further preventing dust and clogging, reducing material waste, and further ensuring overall feeding efficiency and reducing overall production costs. When the filter plates need to be disassembled, simply unscrew the hand-tightening bolts and remove the intermediate pressure plate 26. When the filter plates are not in use and the waterproof cloth 7 needs to be covered, the intermediate pressure plate 26 passes through the elongated hole 27, ensuring that the waterproof cloth 7 fits tightly against the outer frame 17 on both sides of the filter plates and the mesh plate 1, thereby further protecting the filter plates.

[0036] Furthermore, the cleaning assembly includes a connecting plate 28, a scraper 29, a cleaning roller 30, and an air blowing assembly 31 for blowing residual materials on the filter plate and mesh plate 1 down to the underground hopper 2. From back to front, the bottom of the connecting plate 28 is sequentially connected to the air blowing assembly 31, an electric push rod 32, and a rotating frame 33 arranged in an inverted U-shape. Both ends of the cleaning roller 30 are rotatably connected to the two open ends of the rotating frame 33. The cleaning roller 30 has rolling parts 34 at both ends for rolling on the side pressure plate 4. A soft brush 35 is connected to the circumference of the cleaning roller 30. The bottom end of the scraper 29... A clearance hole 36 is provided for the crossbeam 19 to pass through. The top rod of the electric push rod 32 is fixedly connected to the top of the scraper 29. The drive mechanism includes a set of long slide rails 37 located on the other two sides of the outer frame 17 and a linear guide rail 38 installed on one of the long slide rails 37. One end of the connecting plate 28 is fixedly connected to the slider of the linear guide rail 38, and the other end of the connecting plate 28 is slidably connected to the other long slide rail 37. A photoelectric switch 39 for detecting the electric push rod 32 is provided on one side of the long slide rail 37. The photoelectric switch 39 is located above one side of the grid plate 1.

[0037] As described above, when the filter plate needs to be cleaned after the raw materials are unloaded, the intermediate pressure plate 26 is first removed. Then, the motor of the linear guide rail 38 is started, driving the connecting plate 28, scraper 29, electric push rod 32, rotating frame 33, cleaning roller 30, and air blowing assembly 31 to slide along the length of the long slide rail 37 towards the filter plate. When the cleaning roller 30 moves to the filter plate, the rolling part 34 on the cleaning roller 30 rolls on the upper end face of the side pressure plate 4. Driven by the rolling part 34, the cleaning roller 30 rotates while the soft brush 35 cleans the newly residual raw materials in the corners or gaps of the filter plate. The material on the filter plate surface is swept into the underground hopper 2, which serves as a preliminary automatic cleaning of the filter plate. After the cleaning roller 30 has cleaned the area, the scraper 29 scrapes off any remaining material on the surface and passes it through the filter holes and mesh of the grid plate 1, falling into the underground hopper 2, which serves as a secondary automatic cleaning of the filter plate. Then, the air blowing assembly 31 is activated to blow air onto the filter plate after it has been cleaned by the scraper 29, blowing off any remaining new material trapped in the gaps of the filter plate into the underground hopper 2, which serves as a tertiary automatic cleaning of the filter plate.

[0038] Finally, after the cleaning rollers 30, scrapers 29, and air blowing assembly 31 on both sides of the mesh plate 1 have cleaned the filter plate in sequence, the motor of the linear guide rail 38 is reversed to drive the connecting plate 28 to move away from the filter plate along the length of the long slide rail 37 for a reset movement. During this movement, the air blowing assembly 31, scrapers 29, and cleaning rollers 30 continue to clean the filter plate until they leave the filter plate. When passing under the vacuum cleaner, if there is a lot of dust remaining on the surface of the filter plate, the vacuum cleaner can be activated for vacuuming. Additionally, after all the filter plates have been removed... After disassembly and cleaning, when cleaning the mesh plate 1, first start the motor of the linear guide rail 38. The slider of the linear guide rail 38 moves, driving the cleaning component to move along the length of the long slide rail 37. The air blowing component 31 blows the residual material on the mesh plate 1 into the underground hopper 2 in time. During this process, when the scraper 29 moves onto the mesh plate 1, the photoelectric switch 39 detects the scraper 29 signal and sends it to the external controller. The external controller controls the electric push rod 32 to start. The top rod of the electric push rod 32 extends, driving the scraper 29 towards the mesh. As the grid plate 1 descends, the scraper 29 scrapes the raw material adhering to the mesh openings into the underground hopper 2. The clearance hole 36 allows the crossbeam 19 of the grid plate 1 to pass through, preventing interference between the crossbeam 19 and the scraper 29. The push rod of the electric push rod 32 then retracts, causing the scraper 29 to rise and return to its original position above the grid plate 1. While the slider of the linear guide rail 38 moves the cleaning assembly along the length of the long slide rail 37, the process of the electric push rod 32 driving the scraper 29 to rise and fall to clean each row of mesh openings continues until the scraper 29 is moved... When the electric push rod 32 moves to the reinforcing longitudinal rod 21, it rises and resets, then stops retracting and descends. After the scraper 29 moves away from the reinforcing longitudinal rod 21, the electric push rod 32 repeatedly rises and falls, driving the scraper 29 to scrape the raw material in the multiple rows of mesh holes into the underground hopper 2. Then it passes over the reinforcing longitudinal rod 21 until all the mesh holes on the grid plate 1 are cleaned. Then the electric push rod 32 drives the scraper 29 to rise and reset above the grid plate 1. The linear guide rail 38 drives the cleaning component to reset and leave the grid plate 1, thus achieving the function of automatically cleaning the grid plate 1.

[0039] Furthermore, the grid plate 1 is provided with a flip motor 40 on both sides to drive the long slide rail 37 to flip up and down by 90°. The driving end of the flip motor 40 is fixedly connected to one end of the long slide rail 37. The grid plate 1 is provided with a fixing bracket 41 on both sides for placing the long slide rail 37 vertically and fixing the wires.

[0040] As described above, when the filter plate needs to be cleaned after the feed raw materials are unloaded, the middle pressure plate 26 is first removed, and then the flipping motor 40 is started by controlling the external controller (not shown in the figure, the same throughout the text). The drive end of the flipping motor 40 drives the long slide rail 37 to flip downwards towards the other two sides near the outer frame 17 until the vertically placed long slide rail 37 flips to the other two sides of the outer frame 17. Then the drive mechanism is started. When all cleaning components leave the filter plate to the initial position, if the long slide rail 37 is considered to be taking up space, the flipping motor 40 can be started to drive the long slide rail 37 to rotate upwards by 90° into the fixed frame 41, reducing the footprint of the long slide rail 37 and the drive mechanism, and preventing dust or raw materials from flying onto the long slide rail 37 and the linear guide rail 38.

[0041] Furthermore, a dustproof box is detachably connected to the long slide rail 37.

[0042] As can be seen from the above description, when unloading is required, the dustproof box can be detachably installed on the long slide rail to avoid dust accumulation and prevent dust or raw materials from flying onto the long slide rail 37 and the linear guide rail 38.

[0043] Furthermore, the dust collection device includes a dust collection hood 42, an air suction pipe 43, and a vacuum cleaner. The dust collection hood 42 is mounted on one side above the mesh plate 1. The bottom of the dust collection hood 42 is connected to a retractable dust cover 44, which is U-shaped and prevents feed material in the middle of the filter plate from being sucked into the dust collection hood 42. Lifting cylinders 13 are installed on both sides of the dust collection hood 42 to drive the retractable dust cover 44 to rise and fall.

[0044] As can be seen from the above description, when a large amount of dust is generated during or immediately after unloading, the dust raised above and below the filter plate is drawn into the suction pipe 43 through the dust hood 42 and then into the vacuum cleaner through the suction pipe 43, thus achieving automatic dust removal. This prevents a large amount of dust from falling onto the filter plate or mesh plate 1 and causing feeding blockage, which would affect the subsequent feeding efficiency. This further improves the feeding efficiency and also reduces the workload of cleaning the filter plate and mesh plate 1.

[0045] Furthermore, the side pressure plate 4 is arranged in an inverted L shape. The horizontal end face of the side pressure plate 4 contacts the upper end face of the grid plate 1 and the upper end face of the fixing frame 5. The vertical end face of the side pressure plate 4 contacts the side of the grid plate 4. The bottom of the vertical end of the side pressure plate 4 contacts the ground.

[0046] As can be seen from the above description, by setting the side pressure plate 4 to an inverted L-shape, the vertical end of the side pressure plate 4 is used to prevent rainwater from flowing into the underground hopper through the gap between the grid plate 1 and the side pressure plate 4, thus avoiding the loss of raw materials and further reducing the overall production cost.

Lifting cylinders 13 are installed on both sides of the dust collection hood 42 to drive the retractable dust cover 44 to rise and fall.

[0056] Example 2 differs from Example 1 in that, as Figure 9 As shown, this embodiment does not have a flip motor 40, the long slide rail is non-rotatable, and a dustproof box (not shown in the figure, the same applies throughout the text) is detachably connected to the long slide rail 37.

[0057] In summary, compared with the prior art, this utility model has the advantages of easy maintenance and cleaning, high feeding efficiency, and reduced production costs. By setting the mesh plate 1 to protrude above the ground at the top, rainwater or other debris is prevented from flowing from the ground through the mesh plate 1 into the underground hopper 2, thereby improving feeding efficiency and reducing overall production costs. The groove 3, side pressure plate 4, and several filter plates increase the overall strength and load-bearing capacity of the mesh plate 1. When replacement or cleaning is required, simply unscrew the bolts, remove the side pressure plate 4, and replace the corresponding filter plate, further reducing overall production costs and enabling the filter plates to be disassembled for cleaning or replacement. Furthermore, by using each filter plate… The filter column 6 is positioned above each mesh opening of the grid plate 1 to prevent small animals such as mice from entering the hopper and causing raw material loss, thereby further reducing the overall production cost. The waterproof cloth 7, barbs 9, hanging rings 8, and automatic winding mechanism serve to shield the filter plate and automatically wind up the waterproof cloth 7. The cleaning component and drive mechanism sweep the residual new raw material on the upper surface of the filter plate or the grid plate 1 into the underground hopper 2, thereby automatically cleaning the filter plate or the grid plate 1. The dust removal device is used to absorb the dust raised during the unloading process, preventing the grid plate 1 and the filter plate from clogging and affecting the feeding efficiency, thereby further improving the overall feeding efficiency.

[0058] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
