Description

Technical Field

[0001] This utility model belongs to the field of feed processing technology, specifically relating to an agricultural forage feed processing and crushing device. Background Technology

[0002] In the livestock farming industry, the grinding and processing of forage is crucial, as its quality directly affects livestock digestion and absorption, as well as farming efficiency. With the large-scale development of animal husbandry, the demand for efficient and precise forage grinding equipment is becoming increasingly urgent.

[0003] A review of the publicly disclosed (announcement) number CN214338770U reveals a multi-bacterial forage pulverizing device. This technology uses only a simple pulverizing blade to pulverize the forage, a method that is insufficient for processing long pieces of forage. Once long pieces of forage enter the pulverizing area, they easily entangle and accumulate around the pulverizing blade, leading to frequent equipment shutdowns for cleaning. This not only affects the continuity of the processing flow but also causes additional wear on components such as the pulverizing blade due to entanglement, shortening the equipment's lifespan and increasing maintenance costs. Furthermore, this patent lacks an effective grading and screening mechanism, resulting in uneven particle size in the pulverized material, with large particles present. This fails to meet the livestock's demand for refined feed, reducing feed utilization and impacting livestock growth and development.

[0004] To address the aforementioned problems, this application proposes an agricultural forage and feed processing and crushing device. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides an agricultural forage processing and pulverizing device. This device solves the problem of long forage entanglement at the source, reduces equipment downtime for cleaning, ensures continuous and stable processing, reduces the risk of component wear due to entanglement, and then efficiently refines short forage into uniform fine particles, avoiding incomplete pulverization and uneven particle size. This significantly improves the fineness of the finished feed, making it easier for livestock to digest and absorb.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an agricultural forage and feed processing and crushing device, comprising a support base, a crushing box fixed to the surface of the support base, and a feeding hopper fixed to the feeding end of the crushing box. The discharging end of the crushing box is fixed with a discharging hopper. The device also includes a crushing and sieving assembly installed inside the crushing box. The crushing and sieving assembly includes a drive shaft rotatably connected to the top of the inside of the crushing box. A cutting blade is fixed to the surface of the drive shaft. Two sets of crushing shafts are arranged below the cutting blades. Crushing blades are fixed to the surface of the crushing shafts. A sieve is arranged below the crushing blades. Sliding wheels are arranged on both sides of the bottom of the sieve. The sliding wheels are fixed inside the crushing box by a bracket, and the sieve is slidably connected to the surface of the sliding wheels.

[0007] Preferably, a drive motor is fixed on one side of the crushing box, the output end of the drive motor is connected to one end of the drive shaft, and transmission gears are fixed on the ends of the two sets of crushing shafts away from the drive motor, and the two sets of transmission gears mesh with each other. A transmission chain is connected between the end of the drive shaft near the transmission gear and one end of one set of crushing shafts through a sprocket drive.

[0008] Preferably, one end of the crushing shaft away from the transmission gear is fixed with a bevel gear pair, and a worm gear is rotatably connected to the side of the crushing box surface near the bevel gear pair via a bearing seat. The bevel gear pair consists of two meshing bevel gears, one bevel gear is fixed to one end of the crushing shaft, and the other bevel gear is fixed to one end of the worm gear.

[0009] Preferably, the worm gear is meshed with a worm wheel, and a drive shaft is fixed inside the worm wheel. The drive shaft is rotatably connected to the surface of the crushing chamber through a bearing seat, and eccentric discs are fixed at both ends of the drive shaft. A hinge rod is hinged to the surface of the eccentric disc, and a hinge seat is hinged to the other end of the hinge rod. The hinge seat is fixed at the end of the screen. The clearance window opened inside the crushing chamber provides space for the reciprocating motion of the hinge seat and the screen, avoiding jamming of the components.

[0010] Preferably, the crushing box has a clearance window inside for the hinge seat and the screen to pass through. The screen is inclined along the material conveying direction, and the thickness of the screen near the hinge seat is greater than that near the material output end, gradually decreasing in thickness. The aperture of the screen remains consistent along the material conveying direction. Driven by the hinge seat, the screen slides back and forth along the surface of the sliding wheel to achieve vibration screening. At the same time, the inclined screen along the material conveying direction and the thickness near the hinge seat being greater than that at the output end, combined with the reciprocating vibration, can push the material towards the output end. The gradually changing thickness design ensures the overall structural stability of the screen and avoids local stress concentration.

[0011] Preferably, it also includes a return conveying assembly installed on one side of the crushing box. The return conveying assembly includes a conveying cylinder fixed to the surface of the support base. A conveying auger is rotatably connected inside the conveying cylinder. A driven gear is fixed to the top of the conveying auger. A driving gear is meshed with the surface of the driven gear. A rotating shaft is fixed inside the driving gear, and the rotating shaft is rotatably connected to the surface of the crushing box through a bearing seat.

[0012] Preferably, a bevel gear pair two is fixed at the bottom end of the rotating shaft. The bevel gear pair two consists of two meshing bevel gears. One bevel gear is fixed at the bottom end of the rotating shaft, and the other bevel gear is fixed at one end of the crushing shaft. A receiving hopper is fixed at the feed end of the conveying cylinder, and the receiving hopper is directly opposite the output end of the screen. A return pipe is fixed at the discharge end of the conveying cylinder, and the other end of the return pipe extends to the top of the crushing box.

[0013] Preferably, the cutting blades are spirally distributed on the surface of the drive shaft, and the distance between two adjacent sets of cutting blades is 3-5 cm. The shredders are staggered and welded to the surface of the shredder shaft, and the blades of the shredders are provided with a serrated structure. The rotating cutting blades cut long hay into short segments, preventing long hay from tangling with subsequent components, and at the same time, pre-treating for fine shredding. The staggered welded shredders generate shearing force through high-speed rotation, further shredding the short hay into fine particles. The serrated structure can enhance the shredding effect on fibrous hay and prevent slippage.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The set crushing and screening components can first cut long hay into short segments to avoid local accumulation. At the same time, the short segment treatment solves the problem of long hay tangling from the source, reduces the frequency of equipment downtime for cleaning, ensures continuous and stable processing, and reduces the risk of component wear caused by tangling. Then, the short hay is efficiently refined into uniform fine particles, avoiding incomplete crushing and uneven particle size, significantly improving the fineness of the finished feed and making it easier for livestock to digest and absorb.

[0016] It can quickly separate materials of different particle sizes, preventing qualified particles from clogging the screen holes. At the same time, the screen is set at an angle along the material conveying direction. The vibration and tilting force are superimposed, which can automatically push the material to the output end. No additional conveying components are required, which simplifies the structure and prevents material from accumulating on the screen surface, thus improving screening efficiency. The finished particles after screening are uniform in size, meet the feed processing standards, and can be used directly without secondary processing, improving the practicality and economy of the overall processing flow.

[0017] 2. Through the set return conveying component, larger particles that have not passed through the screen can be automatically conveyed back to the inside of the crushing box. The collection of substandard materials can be completed without manual intervention, avoiding the loss caused by particle accumulation and scattering. Compared with the manual cleaning and recycling mode, it realizes the closed-loop recycling of materials in the entire process, improves resource utilization efficiency, reduces labor costs, and avoids the impact of manual operation on the continuity of the processing process. It is especially suitable for large-scale, continuous forage and feed processing scenarios.

[0018] Larger particles that are recycled are fed back into the crushing chamber for further crushing and sieving until the particle size meets the sieve size standard. This multi-cycle crushing mode can effectively avoid the problem of large particles mixed in the finished product due to incomplete crushing in a single cycle, ensuring that the feed particles discharged from the hopper are of uniform size, meeting the particle size requirements for livestock consumption or subsequent processing, and improving the overall quality of feed products.

[0028] like Figures 1-6 As shown:

[0029] An agricultural forage and feed processing and crushing device includes a support base 1, a crushing box 2 fixed to the surface of the support base 1, and a feed hopper 3 fixed to the feed end of the crushing box 2. A discharge hopper 4 is fixed to the discharge end of the crushing box 2. The device also includes a crushing and screening assembly 5 installed inside the crushing box 2. The crushing and screening assembly 5 includes a drive shaft 502 rotatably connected to the top of the inside of the crushing box 2. A cutting blade 501 is fixed to the surface of the drive shaft 502. Two sets of crushing shafts 505 are arranged below the cutting blades 501. Crushing blades 504 are fixed to the surface of the crushing shafts 505. A screen 515 is arranged below the crushing blades 504. Sliding wheels 516 are arranged on both sides of the bottom of the screen 515. The sliding wheels 516 are fixed inside the crushing box 2 by a bracket, and the screen 515 is slidably connected to the surface of the sliding wheels 516.

[0030] A drive motor 503 is fixed on one side of the crushing box 2. The output end of the drive motor 503 is connected to one end of the drive shaft 502. A transmission gear 507 is fixed at the end of each of the two crushing shafts 505 away from the drive motor 503, and the two sets of transmission gears 507 mesh with each other. A transmission chain 506 is connected between the end of the drive shaft 502 near the transmission gear 507 and one end of one of the crushing shafts 505 through a sprocket drive.

[0031] One of the crushing shafts 505 has a bevel gear pair 508 fixed at the end away from the transmission gear 507. The worm gear 509 is rotatably connected to the side of the surface of the crushing box 2 near the bevel gear pair 508 through a bearing seat. The bevel gear pair 508 consists of two meshing bevel gears, one of which is fixed at one end of the crushing shaft 505 and the other is fixed at one end of the worm gear 509.

[0032] The worm gear 509 is meshed with a worm wheel 510. The worm wheel 510 has a drive shaft 511 fixed inside. The drive shaft 511 is rotatably connected to the surface of the crushing box 2 through a bearing seat. Both ends of the drive shaft 511 are fixed with eccentric discs 512. The surface of the eccentric disc 512 is hinged with a hinge rod 513. The other end of the hinge rod 513 is hinged with a hinge seat 514. The hinge seat 514 is fixed at the end of the screen 515.

[0033] The crushing box 2 has a clearance window for the hinge seat 514 and the screen 515 to pass through. The screen 515 is inclined along the material conveying direction, and the thickness of the screen 515 near the hinge seat 514 is greater than the thickness near the material output end, and gradually decreases. The screen hole diameter on the screen 515 is consistent along the material conveying direction.

[0034] It also includes a return conveying assembly 6 installed on one side of the crushing box 2. The return conveying assembly 6 includes a conveying cylinder 601 fixed to the surface of the support base 1. A conveying auger 602 is rotatably connected inside the conveying cylinder 601. A driven gear 603 is fixed at the top of the conveying auger 602. A driving gear 604 is meshed with the surface of the driven gear 603. A rotating shaft 605 is fixed inside the driving gear 604. The rotating shaft 605 is rotatably connected to the surface of the crushing box 2 through a bearing seat.

[0035] A bevel gear pair 606 is fixed at the bottom end of the rotating shaft 605. The bevel gear pair 606 consists of two meshing bevel gears. One bevel gear is fixed at the bottom end of the rotating shaft 605, and the other bevel gear is fixed at one end of the crushing shaft 505. A receiving hopper 607 is fixed at the feed end of the conveying cylinder 601, and the receiving hopper 607 is directly opposite the output end of the screen 515. A return pipe 608 is fixed at the discharge end of the conveying cylinder 601, and the other end of the return pipe 608 extends to the top of the crushing box 2.

[0036] The cutting blades 501 are spirally distributed on the surface of the drive shaft 502, and the distance between two adjacent sets of cutting blades 501 is 3-5cm. The crushing blades 504 are staggered and welded to the surface of the crushing shaft 505, and the blades of the crushing blades 504 are provided with a serrated structure.

[0037] The working principle and usage process of this utility model are as follows: The device uses the support base 1 as the overall bearing foundation. The crushing and screening component 5 realizes the grading, crushing and screening of forage. The return conveying component 6 completes the secondary crushing of substandard materials. Finally, qualified feed is output through the discharge hopper 4. After the device is started, the drive motor 503 fixed on one side of the crushing box 2 outputs power to directly drive the drive shaft 502 connected to its output end to rotate, providing initial power for all subsequent actions. When the drive shaft 502 rotates, the end of it near the transmission gear 507 transmits power to one of the crushing shafts 505 through the sprocket and transmission chain 506, driving the crushing shaft 505 to rotate. The ends of both crushing shafts 505 away from the drive motor 503 are fixed with transmission gears 507, and the two sets of gears mesh with each other. Therefore, when one set of crushing shafts 505 rotates, it will drive the other set of crushing shafts 505 to rotate synchronously in the opposite direction through gear meshing, preparing for subsequent crushing actions.

[0038] Furthermore, the chain-driven crushing shaft 505 has a bevel gear pair 508 (composed of two meshing bevel gears) fixed at the end away from the transmission gear 507. This bevel gear pair converts the horizontal rotational power of the crushing shaft 505 into a vertical direction and transmits it to the worm gear 509 connected to it, causing the worm gear 509 to rotate. The worm gear 509 meshes with the worm wheel 510, further transmitting the power to the transmission shaft 511, which is fixed with the worm wheel 510, causing the transmission shaft 511 to rotate around its own axis. One set of crushing shafts 505 also transmits rotational power to the rotating shaft 605 through a bevel gear pair 606 (composed of two meshing bevel gears). The driving gear 604 fixed on the surface of the rotating shaft 605 meshes with the driven gear 603 at the top of the conveying auger 602, ultimately driving the conveying auger 602 inside the conveying cylinder 601 to rotate, providing power for the return conveying.

[0039] Furthermore, the hay to be processed enters the device through the feed hopper 3 at the feed end of the crushing box 2. It first contacts the spirally distributed cutting blades 501 on the surface of the drive shaft 502. The rotating cutting blades 501 cut long hay into short segments, preventing long hay from tangling with subsequent components and pre-treating for fine crushing. The cut short hay falls between two sets of crushing shafts 505, which rotate synchronously in opposite directions. The crushing blades 504 (with serrated blades) welded to their surfaces generate shearing force through high-speed rotation, further crushing the short hay into fine particles. The serrated structure enhances the crushing effect on fibrous hay and prevents slippage. When the drive shaft 511 rotates, the eccentric discs 512 fixed at both ends synchronously perform eccentric circular motion. The eccentric discs 512, through the hinged hinge rod 513, drive the hinge seat 514 connected to the other end of the hinge rod 513 to move in a forward direction. The screen 515 undergoes a double linear motion. The hinge seat 514 is fixed at the end of the screen 515, and the bottom two sides of the screen 515 are slidably connected by sliding wheels 516. Therefore, the screen 515 slides back and forth along the surface of the sliding wheels 516 under the drive of the hinge seat 514, realizing vibration screening. At the same time, the screen 515 is inclined along the material conveying direction, and the thickness of the end near the hinge seat 514 is greater than that of the output end. The inclined structure, combined with the reciprocating vibration, can push the material to move towards the output end. The gradual thickness design ensures the overall structural stability of the screen 515 and avoids local stress concentration. The crushed material falls onto the surface of the screen 515, and the fine particles that meet the screen aperture pass through the screen holes and are finally discharged from the discharge hopper 4 at the discharge end of the crushing box 2, becoming qualified feed products. The clearance window opened inside the crushing box 2 provides space for the reciprocating motion of the hinge seat 514 and the screen 515, avoiding component jamming.

[0040] Furthermore, larger particles that do not pass through the sieve 515 fall into the receiving hopper 607 directly opposite the sieve 515 output end under the action of the inclined structure and vibration, and then enter the conveying cylinder 601. The rotating conveying auger 602 conveys the larger particles upward along the conveying cylinder 601, and finally sends them back into the crushing box 2 through the return pipe 608 at the discharge end of the conveying cylinder 601. Together with the newly entered forage, they undergo the cutting and crushing process again until they reach the qualified particle size, realizing material recycling and improving crushing efficiency and finished product qualification rate.

[0041] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
