Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a feed storage device. Background Technology

[0002] Feed storage is a crucial link between production and breeding, and its necessity is particularly prominent: the demand for feed from the breeding end is continuous and stable, while the production of raw materials and feed processing tools are seasonal, and storage is needed to balance the time difference between supply and demand; feed is easily affected by temperature, humidity and oxygen in the natural environment, resulting in mold, clumping and nutrient loss. The functional components in compound feed are even more sensitive, and improper storage can reduce quality or even breed harmful substances, threatening the health of pigs and food safety.

[0003] A pig feed storage silo, disclosed in authorization announcement number (CN223303343U), includes a silo body. An exhaust unit is installed on the inner top wall of the silo body, and a filter plate is fixed to the inner wall of the silo body, positioned below the exhaust unit. A stirring assembly is located at the bottom of the filter plate. During actual operation, a stirring motor drives a stirring rod to rotate, which in turn drives several stirring blades to rotate synchronously, achieving uniform stirring of the feed within the silo and preventing feed clumping.

[0004] The structure disclosed in this patent has defects in practical applications, specifically as follows: the stirring rod extends deep into the inner cavity of the cylinder, and multiple stirring blades are mounted on the stirring rod, which occupies a large amount of effective storage space in the cylinder, directly reducing the amount of feed stored; at the same time, the large accumulation of feed deep in the cylinder results in high stirring resistance, causing the stirring blades to face greater resistance when stirring, which not only significantly increases the difficulty of stirring, but also makes it difficult to achieve uniform stirring of materials, ultimately affecting the anti-caking effect. Utility Model Content

[0005] The purpose of this utility model is to provide a feed storage device that addresses the problem in the prior art where the stirring structure occupies a large amount of effective storage space and the stirring resistance is high after the feed accumulates deep inside the cylinder. This device can save effective storage space inside the cylinder and significantly reduce the risk of feed clumping during storage.

[0006] This utility model is achieved through the following technical solution:

[0007] A feed storage device includes: a frame; a storage cylinder mounted on the frame, with a feed inlet at the top and a discharge port at the bottom; a dispersing cylinder mounted on the top of the storage cylinder, the interior of which communicates with the feed inlet, and a guide port on the side wall of the dispersing cylinder; a dispersing assembly mounted on the dispersing cylinder, capable of dispersing the feed inside the dispersing cylinder; and a feed conduit arranged at an incline, communicating with the guide port.

[0008] Furthermore, in this utility model, the above-mentioned dispersing component includes: a motor, which is installed at the top of the dispersing cylinder; a rotating main shaft, one end of which is connected to the output end of the motor, and the other end of which passes through the dispersing cylinder and extends into the interior of the dispersing cylinder; and multiple dispersing blades, which are installed on the outer wall of the rotating main shaft and can disperse the feed inside the dispersing cylinder.

[0009] Furthermore, in this utility model, a feed sieve plate is installed at the bottom of the above-mentioned dispersing cylinder, and a plurality of screening holes are opened on the feed sieve plate; wherein, after the feed in the dispersing cylinder is dispersed, the feed that meets the requirements of the screening hole diameter can fall into the storage cylinder through the screening hole.

[0010] Furthermore, in this utility model, a sleeve is fitted at the end of the rotating main shaft away from the motor, and at least one pusher scraper is assembled on the side wall of the sleeve along the circumferential direction; wherein, the pusher scraper can be set with a preset gap with the feed screen plate, and the pusher scraper can push the material on the upper surface of the feed screen plate into the screening through hole.

[0011] Furthermore, in this utility model, the inner sidewall of the above-mentioned dispersing cylinder is provided with multiple locking grooves along the circumferential direction; the outer sidewall of the feed sieve plate is provided with multiple receiving channels along the circumferential direction, and the multiple receiving channels are correspondingly arranged with the multiple locking grooves one by one, and locking components are installed in the receiving channels; wherein, the locking components can be detachably locked with the corresponding locking grooves to realize the detachable connection between the feed sieve plate and the dispersing cylinder.

[0012] Furthermore, in this utility model, the locking component includes: a locking block, which is movably disposed within the receiving channel; and an elastic member, which is disposed within the receiving channel, with one end of the elastic member connected to the inner wall of the receiving channel and the other end of the elastic member connected to the locking block; wherein the locking block can be at least partially embedded in the locking groove under the action of the elastic member, thereby locking and positioning the feed sieve plate.

[0013] Furthermore, in this utility model, a guide structure is provided at the end of the locking block away from the elastic member; wherein, when the feed sieve plate is moved upward, the guide structure forms a guiding engagement with the inner wall of the locking groove, driving the locking block to retract into the receiving channel and disengage from the locking groove.

[0014] Furthermore, in this utility model, the sleeve is slidably guided to the rotating spindle; a mounting plate is fixedly fitted at a preset position on the rotating spindle; a return spring is fitted outside the rotating spindle, one end of the return spring is connected to the mounting plate, and the other end of the return spring is connected to the sleeve.

[0015] Furthermore, in this invention, the bottom end of the storage cylinder is configured as a funnel structure.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] 1. This utility model combines the separate layout of the independent dispersing cylinder and the storage cylinder with the operation mode of pre-treatment by the dispersing component, which breaks through the disadvantage of effective space occupation caused by the built-in storage cylinder of the traditional mixing structure, avoids the problems of large dispersing resistance and poor anti-caking effect caused by deep feed accumulation, and significantly improves feed storage capacity and anti-caking efficiency.

[0018] 2. The screening and pushing mechanism of the feed sieve plate and the pusher scraper in this utility model, combined with the detachable connection design of the locking component, overcomes the drawbacks of traditional screening structures that are prone to clogging and cumbersome to maintain and disassemble. It avoids the problem of secondary agglomeration caused by insufficiently dispersed feed entering the storage cylinder, and significantly improves the feed screening throughput and equipment maintenance convenience.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0028] Example

[0029] Please refer to Figures 1 to 5 This utility model provides a feed storage device. It includes a frame 1, a storage cylinder 2, a dispersing cylinder 5, a dispersing assembly, and a feed conduit 7. The frame 1 serves as an integral load-bearing structure, the storage cylinder 2 is mounted on the frame 1, the top of the storage cylinder 2 has a feed port 3, and the bottom of the storage cylinder 2 has a discharge port 4. The dispersing cylinder 5 is fixed to the top of the storage cylinder 2, and its bottom is open, connecting with the feed port 3 of the storage cylinder 2 to form a sealed fit. A guide interface 6 is provided on the side wall of the dispersing cylinder 5. The dispersing assembly is assembled on the dispersing cylinder 5 and is used to disperse the feed inside the dispersing cylinder 5. The feed conduit 7 is arranged at an angle, and one end of the feed conduit 7 is connected to the guide interface 6 for feeding and conveying the feed.

[0030] During feed storage operations, operators feed the feed to be stored through the top of the inlet conduit 7. Under its own weight, the feed naturally slides down the inclined inlet conduit 7 and enters the dispersing cylinder 5 through the feed guide interface 6. The dispersing component disperses the feed entering the dispersing cylinder 5, effectively breaking up any clumps formed during transportation and stacking before storage, resulting in a uniformly dispersed feed. The dispersed feed then falls into the storage cylinder 2 under gravity for storage.

[0031] A pre-treatment dispersing stage is set up before the feed enters the storage hopper 2, ensuring that the feed stored in the storage hopper 2 remains in a dispersed state. This reduces problems such as storage accumulation and discharge blockage caused by feed clumping from the source. At the same time, the dispersed feed reduces the probability of re-clumping during storage, ensuring smooth subsequent discharge. Compared with the traditional design of building the dispersing device into the dry storage hopper 2, this design does not occupy the internal storage space of the storage hopper 2, effectively increasing the actual storage capacity of the storage hopper 2. At the same time, the dispersing component does not need to extend into the storage hopper 2, avoiding the problem of excessive load caused by working deep into a large amount of feed, reducing component operating energy consumption and mechanical wear, extending the service life of the device, and simplifying later maintenance operations.

[0032] It should be noted that the top of the dispersing cylinder 5 and the discharge port 4 are equipped with opening and closing valves (manual butterfly valves or manual gate valves), which can be closed after the feed feeding operation is completed, thereby blocking the communication channel between the inside of the storage cylinder 2 and the external environment, effectively reducing the entry of external water vapor, dust and debris into the storage cylinder 2, preventing the feed from deteriorating due to moisture and contamination, and ensuring the stability of the feed storage quality.

[0033] Please refer to Figure 3 In some embodiments of this application, the dispersing assembly includes a motor 8, a rotating main shaft 12, and multiple dispersing blades 13. The motor 8 is mounted on the top of the dispersing cylinder 5. One end of the rotating main shaft 12 is connected to the output end of the motor 8, and the other end passes through the top wall of the dispersing cylinder 5 and extends into the interior of the dispersing cylinder 5. The multiple dispersing blades 13 are evenly assembled along the outer side wall of the rotating main shaft 12. In actual operation, after the motor 8 starts, it drives the rotating main shaft 12 to rotate. The rotating main shaft 12 synchronously drives the multiple dispersing blades 13 to rotate inside the dispersing cylinder 5. Through the mechanical impact and stirring action of the dispersing blades 13 with the feed, the efficient dispersing of clumps of feed inside the dispersing cylinder 5 is achieved.

[0034] It should be noted that the connection between the rotating main shaft 12 and the dispersing cylinder 5 adopts a mechanical seal structure, which can effectively block the flow of feed dust and airflow inside the dispersing cylinder 5 to the external environment. This not only avoids environmental pollution caused by dust leakage, but also prevents external moisture and debris from entering the dispersing cylinder 5 through the gap.

[0035] Please refer to Figure 2 and Figure 3 In some embodiments of this application, a feed sieve plate 10 is fitted at the bottom of the dispersing cylinder 5, and the feed sieve plate 10 has multiple screening holes 11. After the feed enters the dispersing cylinder 5, it falls to the bottom under its own gravity. The feed sieve plate 10 intercepts the falling feed, and the clumps of feed that do not meet the aperture requirements of the screening holes 11 are retained on the upper surface of the feed sieve plate 10 and continuously subjected to the dispersing treatment of the dispersing blades 13 until the feed is dispersed to meet the aperture requirements. Only then can the feed fall into the storage cylinder 2 through the screening holes 11 for storage, effectively avoiding the problem of secondary clumping or discharge blockage caused by insufficiently dispersed feed directly entering the storage cylinder 2.

[0036] Please refer to Figure 2 and Figure 3In some embodiments of this application, a sleeve 15 is fitted onto the end of the rotating main shaft 12 away from the motor 8. At least one pusher scraper 17 is mounted on the side wall of the sleeve 15 along the circumferential direction. The pusher scraper 17 is arranged with a predetermined gap from the upper surface of the feed screen plate 10. In actual operation, the rotation of the rotating main shaft 12 drives the sleeve 15 to rotate synchronously. The sleeve 15 then drives the pusher scraper 17 to move circumferentially along the upper surface of the feed screen plate 10. The pusher scraper 17 can push the feed accumulated on the feed screen plate 10, effectively preventing the feed from accumulating and clogging at the screening holes 11. At the same time, it increases the frequency of contact between the feed and the screening holes 11, significantly improving the screening pass rate and feeding efficiency of the feed.

[0037] It should be noted that the upper surfaces of the pusher scraper 17 and the feed screen plate 10 are arranged with a preset gap. The gap size is designed to ensure that the pusher scraper 17 can effectively push the feed accumulated on the feed screen plate 10 when it rotates, ensuring full contact between the feed and the screening holes 11. At the same time, it can avoid direct contact between the pusher scraper 17 and the feed screen plate 10, eliminating wear caused by friction from the root, extending the service life of the pusher scraper 17 and the feed screen plate 10, and reducing maintenance costs caused by wear.

[0038] Please refer to Figures 3 to 5 In some embodiments of this application, the inner sidewall of the dispersing cylinder 5 is provided with a plurality of locking grooves 22 along the circumferential direction. Correspondingly, the outer sidewall of the feed sieve plate 10 is provided with a plurality of receiving channels 20 along the circumferential direction. The receiving channels 20 and the locking grooves 22 are arranged in a one-to-one correspondence, and each receiving channel 20 is equipped with a locking component. Through the detachable locking engagement of the locking component with the corresponding locking groove 22, a detachable connection structure between the feed sieve plate 10 and the dispersing cylinder 5 is formed.

[0039] During installation, align each receiving channel 20 with its corresponding locking groove 22. The locking assembly and the locking groove 22 will engage to secure the feed screen plate 10. During disassembly, release the locking assembly from the locking groove 22 to remove the feed screen plate 10 from the dispersing cylinder 5. The detachable structure facilitates the maintenance of the feed screen plate 10. It allows for regular cleaning of residual feed impurities on the screen plate to prevent clogging of the screening holes 11 and ensure screening efficiency. It also allows for individual replacement of the feed screen plate 10 after wear, reducing the maintenance cost of the device.

[0040] Please refer to Figure 1It should be noted that the storage cylinder 2 is detachably equipped with a maintenance cover 9. When it is necessary to disassemble, clean, or replace the feed sieve plate 10, the operator can first remove the maintenance cover 9 and then perform operations such as locking and unlocking the feed sieve plate 10 at the bottom of the dispersing cylinder 5 inside the storage cylinder 2. To ensure the sealing performance of the storage cylinder 2, a sealing ring is provided at the mating surface between the maintenance cover 9 and the storage cylinder 2. Through the sealing effect of the sealing ring, the airtightness and cleanliness of the feed storage environment are ensured.

[0041] Please refer to Figure 5 Specifically, the locking assembly includes a locking block 18 and an elastic element 21. The locking block 18 is movably embedded in the receiving channel 20, and the elastic element 21 is also disposed in the receiving channel 20. One end of the elastic element 21 is connected to the inner wall of the receiving channel 20, and the other end is connected to the locking block 18. Under the elastic force of the elastic element 21, the locking block 18 can extend at least partially out of the receiving channel 20 and embed into the corresponding locking groove 22, thereby forming a locking and positioning of the feed screen plate 10. When disassembling the feed screen plate 10, the locking block 18 is disengaged from the locking groove 22 and retracted into the receiving channel 20 by external force, and the feed screen plate 10 can be removed.

[0042] It should be noted that the elastic element 21 can be a spring, and the mating part between the locking block 18 and the receiving channel 20 can adopt a mechanical seal structure, which can effectively prevent feed particles from entering the receiving channel 20, thus avoiding affecting the flexibility of the locking block 18 and the working reliability of the elastic element 21. In addition, a telescopic protective sleeve can be fitted on the outside of the spring. One end of the protective sleeve is connected to the locking block 18, and the other end is fixed to the inner wall of the receiving channel 20, further forming a wrap-around protection for the spring and preventing feed dust or impurities from adhering to the spring surface.

[0043] For example, the end of the locking block 18 away from the elastic element 21 is provided with a guide structure 19. The guide structure 19 can form a guiding engagement with the inner wall of the locking groove 22 during the disassembly of the feed screen plate 10, driving the locking block 18 to retract into the receiving channel 20 to disengage from the locking groove 22. In specific disassembly, the operator applies upward force to move the feed screen plate 10, and the locking block 18 moves upward synchronously with the feed screen plate 10. The guide structure 19 at the end of the locking block 18 contacts the inner wall of the locking groove 22 and forms a guiding effect. Under the force, the locking block 18 overcomes the elastic force of the elastic element 21 and retracts into the receiving channel 20, completely disengaging from the locking groove 22. Then, the operator rotates the feed screen plate 10 by a preset angle to make the receiving channel 20 and the locking groove 22 misaligned. At this time, moving the feed screen plate 10 downward can avoid the limitation of the locking groove 22 and smoothly remove the feed screen plate 10 from the dispersing cylinder 5.

[0044] It should be noted that the guide structure 19 is only located in the upper area of ​​the locking block 18, so that the guide structure 19 only forms a guiding engagement with the inner wall of the locking groove 22 when the locking block 18 moves upward. After the feed screen plate 10 is installed in place, the locking block 18 is embedded in the locking groove 22 under the action of the elastic element 21. At this time, under the combined action of its own weight and the elastic force of the elastic element 21, the lower end of the locking block 18 is tightly fitted and limited against the inner wall of the locking groove 22. Since the lower end of the locking block 18 is not provided with the guide structure 19, the fitted and limited state can form a locking effect, ensuring that the feed screen plate 10 will not accidentally loosen or fall out of the installation position during operation.

[0045] For example, the sleeve 15 and the rotating main shaft 12 are in a sliding guide fit. The rotating main shaft 12 is fixedly fitted with a mounting plate 14 at a preset position. A return spring 16 is fitted on the outside of the rotating main shaft 12. One end of the return spring 16 is connected to the mounting plate 14, and the other end is connected to the sleeve 15. To ensure the efficiency of the pushing scraper 17 in pushing and cleaning the feed on the feed screen plate 10, the pushing scraper 17 and the feed screen plate 10 need to be arranged with a relatively close gap. When the operator moves the feed screen plate 10 upward to disassemble it, the feed screen plate 10 simultaneously pushes the sleeve 15 to slide upward along the rotating main shaft 12. At this time, the return spring 16 is compressed by the squeezing of the sleeve 15 and the mounting plate 14. After the feed screen plate 10 has completed the rotational misalignment and can be easily removed, the force on the sleeve 15 is released, the return spring 16 resets and drives the sleeve 15 to slide down along the rotating main shaft 12 to the initial position, ensuring that the pushing scraper 17 can still maintain the preset gap fit state in subsequent operations.

[0046] The feed sieve plate 10 may also have a clearance opening at its center that is compatible with the rotating main shaft 12. The size of the clearance opening matches the cross-sectional profile of the rotating main shaft 12, ensuring that the feed sieve plate 10 can smoothly avoid the rotating main shaft 12 during upward movement and disassembly / reassembly, thus ensuring the smoothness of the disassembly / reassembly operation.

[0047] It should be noted that the guide mating part between the rotating spindle 12 and the sleeve 15 adopts a polygonal cross-section design. The corresponding section of the rotating spindle 12 has a polygonal structure, and the inner wall of the sleeve 15 is also machined into a matching polygonal contour. This ensures that the rotating spindle 12 can synchronously drive the sleeve 15 and the pusher scraper 17 to rotate when it rotates; at the same time, the guiding characteristics of the polygonal mating allow the sleeve 15 to slide freely along the axial direction of the rotating spindle 12.

[0048] The return spring 16 is fitted with a telescopic protective sleeve (such as a bellows). One end of the telescopic protective sleeve is connected to the mounting plate 14, and the other end is fixed to the sleeve 15. The telescopic protective sleeve forms a fully enclosed protective structure for the return spring 16. This effectively prevents feed particles and dust from directly contacting the return spring 16, avoiding problems such as jamming, corrosion, or loss of elasticity caused by feed corrosion, and ensuring the long-term stable telescopic return performance of the return spring 16.

[0049] In some embodiments of this application, the bottom end of the storage cylinder 2 is designed as a funnel structure, which can use the weight of the feed itself to guide the feed to converge towards the discharge port 4, effectively avoiding the accumulation and residue of feed at the bottom of the storage cylinder 2, while improving the smoothness and efficiency of discharge.

[0050] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
