Description

Technical Field

[0001] This invention belongs to the technical field of bulk material silo loading and unloading equipment, specifically relating to a bulk material silo loading and unloading operation system and operation method for feed production. Background Technology

[0002] Feed production is a core component of modern agriculture and animal husbandry, involving extensive raw material storage, transfer, and distribution. With the expansion of feed production scale, large bulk feed silos are widely used for centralized feed storage. Traditional bulk feed silo loading and unloading systems typically employ simple elevators combined with screw conveyors to transport feed to the top entrance of different silos, where the material falls into the silo by its own weight to complete loading and unloading.

[0003] In the feed conveying process, for lightweight, small-particle, or dust-generating materials such as fish and shrimp feed, traditional screw conveyors are prone to material adhesion and blockage at the edges of the screw blades and the inner wall of the barrel, causing conveying interruptions. To resolve blockages, manual cleaning is usually required, which not only affects production continuity and increases the intensity of manual maintenance but also poses certain safety hazards. Meanwhile, in the storage stage, materials fall directly from a high feed inlet to the bottom of the silo, several meters to over ten meters deep. This significant drop can easily lead to increased breakage rates of materials (especially brittle materials such as extruded and micro-particle feeds) under high-speed impact, generating a large amount of powder. This not only causes nutrient loss and feed waste but also affects the particle integrity and palatability of the final product. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a bulk material silo loading and unloading operation system and operation method for feed production.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a bulk feed bin loading and unloading operation system and operation method for feed production, including a fixed main frame, an installation frame fixedly installed on the upper end of the fixed main frame, multiple sets of storage bins fixedly installed on the upper end of the installation frame, anti-breakage and flow guiding components installed in each of the multiple sets of storage bins, a fixed top frame fixedly connected to the upper end of the installation frame, a rib frame installed in the fixed top frame, a distribution and conveying component fixedly installed at the lower end of the rib frame, multiple sets of drive components evenly arranged at the lower end of the distribution and conveying component; multiple sets of fixed shelves evenly installed from top to bottom on the fixed main frame, and a conveyor fixedly installed on one side of the fixed main frame.

[0006] With the above technical solution, when feed needs to be transported to the storage silo, it can be transported to the top of the distribution and conveying components by a transporter, thereby realizing the separate transportation of feed to different silos.

[0007] Preferably, multiple sets of reinforcing steel bars are fixedly installed at the lower end of one side of the fixed main frame, and multiple sets of reinforcing ribs are installed at the upper end of one side of the fixed main frame.

[0008] Preferably, each of the multiple sets of storage silos is fixedly installed with a feed pipe at its upper end, and a buffer silo is fixedly installed at the lower end of each of the multiple sets of storage silos. A distribution pipe is fixedly installed at the lower end of each adjacent buffer silo, and a bulk material silo is fixedly installed at the lower end of each distribution pipe. The bulk material silo is fixedly installed between the bulk material silo and the fixed shelf.

[0009] With the above technical solution, when it is necessary to unload feed, the truck is driven to the bottom of the corresponding bulk feed bin, the valve under the bulk feed bin is opened, and the feed can be moved from the bulk feed bin to the truck.

[0010] Preferably, the anti-shatter guide assembly includes a fixed box that is fixedly installed on the inner wall of the storage bin. The fixed boxes are symmetrically arranged in the storage bin. On one side, multiple sets of first guide plates are uniformly rotatably connected between the fixed boxes from top to bottom. On the other side, multiple sets of second guide plates are uniformly rotatably connected between the fixed boxes from top to bottom. The ends of the multiple sets of first guide plates and second guide plates away from the fixed boxes are respectively connected by connecting ropes.

[0011] Through the above technical solution, the connecting rope can improve the stability between multiple sets of first and second guide plates. The setting of the first and second guide plates can prevent the feed from being damaged due to a large height difference during storage.

[0012] Preferably, the first guide plate and the second guide plate are fixedly connected to the mounting shaft at both ends, a connecting rod is fixedly installed on the mounting shaft, a drive rod is rotatably connected to the other end of the connecting rod, a sliding rod is fixedly installed on one side of the drive rod, a limit block is fixedly connected to one end of the sliding rod, a sliding sleeve is slidably connected to the outside of the sliding rod, a connecting block is fixedly connected to the sliding sleeve, one side of the connecting block is fixedly connected to the output end of the first hydraulic cylinder, and the first hydraulic cylinder is fixedly installed on the inner wall of the fixed box.

[0013] Through the above technical solution, the output end of the first hydraulic cylinder drives the sliding sleeve to move back and forth through the connecting block. The sliding rod drives the drive rod to move under the action of the sliding sleeve, so that the drive rod drives the first guide plate and the second guide plate on the mounting shaft to rotate through the connecting rod. In this way, the first guide plate and the second guide plate on both sides can adjust the dropping interval between them according to the type of feed to be stored.

[0014] Preferably, the distribution and conveying assembly includes a distributor housing fixedly installed between the distributor housing and the rib frame. A motor cover is fixedly connected to one side of the distributor housing. A feed inlet is opened on one side of the upper surface of the distributor housing. Multiple sets of discharge outlets are evenly opened at the lower end of the distributor housing. A drive motor is fixedly connected inside the motor cover. A mounting sleeve is fixedly connected to the output end of the drive motor. A sliding groove is opened on the inner circumference of the mounting sleeve. A slider is slidably connected in the sliding groove. The slider is fixedly connected to the sliding column and to the spiral feeding rod.

[0015] Through the above technical solution, the output end of the drive motor drives the mounting sleeve to rotate, and the mounting sleeve transmits power to the screw feeder through the sliding column, so that the screw feeder drives the feed to move forward.

[0016] Preferably, a fixed disk and a mounting disk are fixedly connected inside the distributor housing. The output end of the drive motor is rotatably connected to the fixed disk. The spiral feed rod is rotatably connected to the mounting disk. A first mounting seat is fixedly connected to one side of the mounting disk. A second mounting seat is rotatably connected to the first mounting seat. The second mounting seat is fixedly connected to an adjusting disk. A second hydraulic cylinder is fixedly installed on one side of the fixed disk. A displacement column is fixedly connected to the output end of the second hydraulic cylinder. A ball bearing seat is fixedly connected to one side of the adjusting disk. Ball bearings are embedded and rolled inside the ball bearing seat. A mounting disk is fixedly installed at one end of the spiral feed rod. A positioning seat is fixedly installed at the end of the spiral feed rod away from the motor cover. A limit seat is slidably connected to the positioning seat. The limit seat is fixedly connected to the distributor housing. A return spring is installed inside the positioning seat.

[0017] Through the above technical solution, the output end of the second hydraulic cylinder pushes the shifting column to move, and the shifting column pushes one end of the adjusting plate, so that the adjusting plate is tilted. At this time, when the mounting plate rotates with the screw feeder, it is affected by the movement state of the adjusting plate, so that the mounting plate drives the screw feeder to reciprocate linearly along the direction of the distributor housing while rotating. When the screw feeder moves towards the motor cover, the positioning seat pushes the return spring to compress. When the screw feeder tends to move towards the feed inlet, the return spring can push the screw feeder back through the positioning seat. This reciprocating motion allows the screw feeder to push out the blocked feed from the edge of the screw feeder while rotating and feeding.

[0018] Preferably, the drive assembly includes a fixed support frame that is fixedly installed to the lower end of the distributor housing, a valve plate that is slidably connected inside the fixed support frame, one end of the valve plate being fixedly installed to the output end of the third hydraulic cylinder, and the third hydraulic cylinder being fixedly installed between the fixed support frame and the third hydraulic cylinder.

[0019] Using the above technical solution, the third hydraulic cylinder is activated, and the output end of the third hydraulic cylinder drives the valve plate to slide along the fixed support frame, opening the outlet of the feed. The feed can be stored in the storage bin through the outlet. Closing the valve plate can close the outlet. The staff can choose to store the feed in the corresponding storage bin as needed.

[0020] The beneficial effects of the present invention are as follows: (1) The present invention designs a distribution and conveying assembly. For small feed pellets, the mounting disc drives the spiral feeding rod to reciprocate linearly along the direction of the distributor housing while rotating. When the spiral feeding rod moves towards the motor cover, the positioning seat pushes the return spring to compress. When the spiral feeding rod tends to move towards the feed inlet, the return spring can push the spiral feeding rod back through the positioning seat. This reciprocating motion allows the spiral feeding rod to push the blocked feed from the edge of the spiral feeding rod while rotating and feeding, thus helping to break down and disperse the blocked small feed pellets and avoid... Small feed particles accumulate and blockage for a long time. Keep the transport inside the distributor shell smooth, so that they can be more easily washed away by the feed flow inside the distributor shell, ensuring the continuous delivery of feed and improving the transport efficiency of feed; (2) By designing the anti-breakage guide component, the output end of the first hydraulic cylinder drives the sliding sleeve to move back and forth through the connecting block. The sliding rod drives the drive rod to move under the action of the sliding sleeve, so that the drive rod drives the first guide plate and the second guide plate on the mounting shaft to rotate through the connecting rod. Then, the first guide plate and the second guide plate on both sides can adjust the drop interval between them according to the type of feed to be stored, preventing the feed from being damaged due to the large height difference during storage.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] like Figures 1-5As shown, this embodiment of a bulk feed silo loading and unloading system for feed production includes a fixed main frame 1. An installation frame 11 is fixedly installed on the upper end of the fixed main frame 1. Multiple sets of storage silos 2 are fixedly installed on the upper end of the installation frame 11. Anti-breakage and flow-guiding components 3 are installed in each of the multiple sets of storage silos 2. A fixed top frame 13 is fixedly connected to the upper end of the installation frame 11. A reinforcing frame 14 is installed inside the fixed top frame 13. A distribution and conveying component 4 is fixedly installed at the lower end of the reinforcing frame 14. Multiple sets of drive components 5 are evenly arranged at the lower end of the distribution and conveying component 4. Multiple sets of fixed shelves 12 are evenly installed from top to bottom on the fixed main frame 1. A conveyor 17 is fixedly installed on one side of the fixed main frame 1. When feed needs to be transported to the storage silos 2, it can be transported to the top of the distribution and conveying component 4 via the conveyor 17, thereby achieving feed distribution and transportation. Multiple sets of reinforcing steel bars 15 are fixedly installed at the lower end of one side of the fixed main frame 1, and multiple sets of reinforcing ribs 16 are installed at the upper end of one side of the fixed main frame 1.

[0035] like Figures 1-4 As shown, multiple sets of storage bins 2 are fixedly installed with feed pipes 21 at their upper ends, and multiple sets of storage bins 2 are fixedly installed with slowing bins 22 at their lower ends. Adjacent slowing bins 22 are fixedly installed with distribution pipes 23 at their lower ends, and bulk feed bins 24 are fixedly installed at their lower ends. The bulk feed bins 24 are fixedly installed with the fixed shelf 12. When it is necessary to unload the feed, the truck is driven to the bottom of the corresponding bulk feed bin 24, and the valve under the bulk feed bin 24 is opened, so that the feed can be moved from the bulk feed bin 24 into the truck.

[0036] like Figures 1-7As shown, the anti-breakage guide assembly 3 includes a fixed box 30 fixedly installed on the inner wall of the storage bin 2. The fixed boxes 30 are symmetrically arranged in the storage bin 2. On one side, multiple sets of first guide plates 31 are evenly rotatably connected from top to bottom between the fixed boxes 30, and on the other side, multiple sets of second guide plates 32 are evenly rotatably connected from top to bottom between the fixed boxes 30. The ends of the multiple sets of first guide plates 31 and second guide plates 32 away from the fixed boxes 30 are respectively connected by connecting ropes 33. The connecting ropes 33 can improve the stability between the multiple sets of first guide plates 31 and second guide plates 32. The arrangement of the first guide plates 31 and second guide plates 32 can prevent the feed from breaking due to large height differences during storage. The two ends of the first guide plates 31 and second guide plates 32 are respectively fixedly connected to the mounting shaft 34. A connecting rod 35 is fixedly installed on the mounting shaft 34. The other end of 35 is rotatably connected to a drive rod 36. A sliding rod 37 is fixedly installed on one side of the drive rod 36. A limit block 38 is fixedly connected to one end of the sliding rod 37. A sliding sleeve 39 is slidably connected to the outside of the sliding rod 37. A connecting block 310 is fixedly connected to the sliding sleeve 39. One side of the connecting block 310 is fixedly connected to the output end of the first hydraulic cylinder 311. The first hydraulic cylinder 311 is fixedly installed on the inner wall of the fixed box 30. The output end of the first hydraulic cylinder 311 drives the sliding sleeve 39 to move back and forth through the connecting block 310. The sliding rod 37 drives the drive rod 36 to move under the action of the sliding sleeve 39, so that the drive rod 36 drives the first guide plate 31 and the second guide plate 32 on the mounting shaft 34 to rotate through the connecting rod 35. Thus, the first guide plate 31 and the second guide plate 32 on both sides can adjust the feeding interval between them according to the type of feed to be stored.

[0037] like Figures 1-10 As shown, the distribution and conveying assembly 4 includes a distributor housing 40 fixedly installed between the rib frame 14 and the distributor housing 40. A motor cover 41 is fixedly connected to one side of the distributor housing 40. A feed inlet 42 is opened on one side of the upper surface of the distributor housing 40. Multiple sets of discharge outlets 419 are evenly opened at the lower end of the distributor housing 40. A drive motor 43 is fixedly connected inside the motor cover 41. An installation sleeve 45 is fixedly connected to the output end of the drive motor 43. A groove 46 is opened on the inner circumference of the installation sleeve 45. A slider 48 is slidably connected inside the groove 46. The slider 48 is fixedly connected to a sliding column 47 and a screw feed rod 49. The output end of the drive motor 43 drives the installation sleeve 45 to rotate. The installation sleeve 45 transmits power to the screw feed rod 49 through the sliding column 47, so that the screw feed rod 49 drives the feed forward.

[0038] like Figures 1-11As shown, a fixed disk 44 and a mounting disk 410 are fixedly connected inside the distributor housing 40. The output end of the drive motor 43 is rotatably connected to the fixed disk 44. The screw feed rod 49 is rotatably connected to the mounting disk 410. A first mounting seat 412 is fixedly connected to one side of the mounting disk 410. A second mounting seat 413 is rotatably connected to the first mounting seat 412. The second mounting seat 413 is fixedly connected to the adjusting disk 411. A second hydraulic cylinder 415 is fixedly mounted to one side of the fixed disk 44. A shifting column 416 is fixedly connected to the output end of the second hydraulic cylinder 415. A ball bearing seat 417 is fixedly connected to one side of the adjusting disk 411. Ball bearings 418 are embedded and rolled in the ball bearing seat 417. The mounting disk 414 is fixedly mounted to one end of the screw feed rod 49. A positioning seat 420 is fixedly mounted to the end of the screw feed rod 49 away from the motor cover 41. A limit seat 421 is slidably connected to the positioning seat 420. The limit seat 421 is fixedly connected to the distributor housing 40. A reset spring 422 is installed inside the positioning seat 420. The output end of the second hydraulic cylinder 415 pushes the shifting column 416 to move. The shifting column 416 pushes one end of the adjusting plate 411, causing the adjusting plate 411 to tilt. At this time, the mounting plate 414 is affected by the movement state of the adjusting plate 411 when it rotates with the screw feed rod 49. This causes the mounting plate 414 to drive the screw feed rod 49 to reciprocate linearly along the direction of the distributor housing 40 while rotating. When the screw feed rod 49 moves towards the motor cover 41, the positioning seat 420 pushes the reset spring 422 to compress. When the screw feed rod 49 tends to move towards the feed inlet 42, the reset spring 422 can push the screw feed rod 49 back through the positioning seat 420. This reciprocating motion allows the screw feed rod 49 to push out blocked feed from the edge of the screw feed rod 49 while rotating and feeding.

[0039] like Figures 1-8 As shown, the drive assembly 5 includes a fixed support frame 50 fixedly installed at the lower end of the distributor housing 40. A valve plate 52 is slidably connected inside the fixed support frame 50. One end of the valve plate 52 is fixedly installed at the output end of the third hydraulic cylinder 51. The third hydraulic cylinder 51 is fixedly installed between the third hydraulic cylinder 51 and the fixed support frame 50. When the third hydraulic cylinder 51 is started, the output end of the third hydraulic cylinder 51 drives the valve plate 52 to slide along the fixed support frame 50, opening the outlet 419. The feed can be stored in the storage bin 2 through the outlet 419. Closing the valve plate 52 can close the outlet 419. The operator can choose to store the feed in the corresponding storage bin 2 as needed.

[0040] The loading and unloading operation method for bulk feed silos used in feed production includes the following specific steps:

[0041] Step 1: When the feed needs to be transported to the storage bin 2, the feed is transported to the top of the distribution conveying component 4 by the conveyor 17. The feed falls into the distributor housing 40 through the feed inlet 42. The drive motor 43 is started. The output end of the drive motor 43 drives the mounting sleeve 45 to rotate. The mounting sleeve 45 transmits power to the screw feed rod 49 through the sliding column 47, so that the screw feed rod 49 drives the feed to move forward. The third hydraulic cylinder 51 is started. The output end of the third hydraulic cylinder 51 drives the valve plate 52 to slide along the fixed support frame 50, opening the outlet 419. The feed can be stored in the storage bin 2 through the outlet 419.

[0042] Step 2: Start the first hydraulic cylinder 311. The output end of the first hydraulic cylinder 311 drives the sliding sleeve 39 to move back and forth through the connecting block 310. The sliding rod 37 drives the drive rod 36 to move under the action of the sliding sleeve 39. The drive rod 36 drives the first guide plate 31 and the second guide plate 32 on the mounting shaft 34 to rotate through the connecting rod 35. Then, the first guide plate 31 and the second guide plate 32 on both sides can adjust the dropping interval between them according to the type of feed to be stored, so as to prevent the feed from being damaged due to the large height difference during storage.

[0043] Step 3: When the screw feeder 49 jams during transport, the second hydraulic cylinder 415 is activated. The output end of the second hydraulic cylinder 415 pushes the shifting column 416 to move. The shifting column 416 pushes one end of the adjusting plate 411, causing the adjusting plate 411 to tilt. At this time, the mounting plate 414, as it rotates with the screw feeder 49, is affected by the movement of the adjusting plate 411. This causes the mounting plate 414 to drive the screw feeder 49 to reciprocate linearly along the direction of the distributor housing 40 while rotating. When the screw feed rod 49 moves toward the motor cover 41, the positioning seat 420 pushes the return spring 422 to compress. When the screw feed rod 49 tends to move toward the feed inlet 42, the return spring 422 can push the screw feed rod 49 back through the positioning seat 420. This reciprocating motion allows the screw feed rod 49 to push out blocked feed from the edge of the screw feed rod 49 while rotating and feeding, thus avoiding long-term accumulation and blockage, and maintaining smooth transport within the distributor housing 40.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.

A valve plate (52) is slidably connected inside the fixed support frame (50). One end of the valve plate (52) is fixedly installed at the output end of the third hydraulic cylinder (51). The third hydraulic cylinder (51) is fixedly installed between the fixed support frame (50) and the valve plate (52).

9. The method for loading and unloading bulk feed silos for feed production according to any one of claims 1-8, characterized in that, The specific steps include the following: Step 1: When the feed needs to be transported to the storage bin (2), the feed is transported to the top of the distribution conveyor assembly (4) by the conveyor (17). The feed falls into the distributor housing (40) through the feed inlet (42). The drive motor (43) is started. The output end of the drive motor (43) drives the mounting sleeve (45) to rotate. The mounting sleeve (45) transmits power to the screw feed rod (49) through the sliding column (47), so that the screw feed rod (49) drives the feed to move forward. The third hydraulic cylinder (51) is started. The output end of the third hydraulic cylinder (51) drives the valve plate (52) to slide along the fixed support frame (50) to open the outlet (419). The feed can be stored in the storage bin (2) through the outlet (419). Step 2: Start the first hydraulic cylinder (311). The output end of the first hydraulic cylinder (311) drives the sliding sleeve (39) to move back and forth through the connecting block (310). The sliding rod (37) drives the drive rod (36) to move under the action of the sliding sleeve (39). This causes the drive rod (36) to drive the first guide plate (31) and the second guide plate (32) on the mounting shaft (34) to rotate through the connecting rod (35). As a result, the first guide plate (31) and the second guide plate (32) on both sides can adjust the dropping interval between them according to the type of feed to be stored, so as to prevent the feed from being damaged due to the large height difference during storage. Step 3: When the screw feeder (49) jams during transport, the second hydraulic cylinder (415) is activated. The output end of the second hydraulic cylinder (415) pushes the shifting column (416) to move. The shifting column (416) pushes one end of the adjusting plate (411), causing the adjusting plate (411) to tilt. At this time, the mounting plate (414) is affected by the movement state of the adjusting plate (411) as it rotates with the screw feeder (49). This causes the mounting plate (414) to drive the screw feeder (49) to reciprocate linearly along the direction of the distributor housing (40) while rotating through the screw feeder (49). When the screw feed rod (49) moves toward the motor cover (41), the positioning seat (420) pushes the return spring (422) to compress. When the screw feed rod (49) tends to move toward the feed inlet (42), the return spring (422) can push the screw feed rod (49) back through the positioning seat (420). This reciprocating motion allows the screw feed rod (49) to push the blocked feed from the edge of the screw feed rod (49) while rotating to feed the feed, thus avoiding long-term accumulation and blockage, and keeping the transport inside the distributor housing (40) unobstructed.
