Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and more specifically, to a device for uniformly mixing animal feed. Background Technology

[0002] A livestock feed mixing device is a mechanical device used to uniformly mix different feed ingredients. Its core function is to ensure the uniform distribution of each component in the feed, thereby improving the nutritional balance of the feed and the feeding efficiency of animals. This type of device is widely used in livestock breeding, pet food production and aquaculture. It achieves the shearing, diffusion and turning of materials through mechanical stirring to meet specific requirements such as mixing uniformity, sterility and low damage.

[0003] Traditional livestock feed mixing devices employ a single crushing chamber and a fixed hammer design. While this design can effectively crush hard and brittle lumpy grains through impact, it struggles with flexible, high-fiber materials like forage or vines. The fixed hammers cannot generate sufficient shearing and tearing action, leading to material entanglement, slippage, and even blockage of the chamber. This results in intermittent crushing processes and significant efficiency fluctuations. This lack of adaptability to material properties forces the equipment to operate under suboptimal conditions. To achieve the target particle size, it often requires extended crushing time or repeated processing, significantly increasing energy consumption per unit output, exacerbating wear on vulnerable parts like hammers, further driving up operating costs, and resulting in overall low energy efficiency.

[0004] In summary, to improve the mixing efficiency of livestock feed, it is necessary to address the problems of traditional livestock feed mixing devices, which use a single grinding chamber and fixed hammer blade design, resulting in poor adaptability to raw materials with different properties, unstable grinding efficiency, and high energy consumption. The goal is to enable the mixing device to mix different feeds efficiently, uniformly, and energy-savingly. Summary of the Invention

[0005] The present invention provides a uniform mixing device for livestock feed, which aims to solve the following problem: traditional livestock feed mixing devices adopt a single crushing chamber and fixed hammer design, which has poor adaptability to raw materials with different properties, resulting in unstable crushing efficiency and high energy consumption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a livestock feed uniform mixing device, comprising a support frame and a crushing shell and a mixing shell fixedly connected to the support frame. The crushing shell has a top feed inlet and a side feed inlet. A drive shaft is rotatably connected inside the crushing shell. A crushing component is installed on the crushing shell. The output end of the crushing component is connected to one end of the drive shaft. An anti-clogging component is installed at the other end of the drive shaft. The crushing component is used to drive the drive shaft to rotate. A plurality of mounting discs arranged in a linear array are fixedly connected to the drive shaft. A plurality of mounting rods arranged in a circumferential array are fixedly connected to the mounting discs. A plurality of hammer blades are rotatably connected to the mounting rods. A filter screen is fixedly connected inside the crushing shell.

[0007] In a preferred embodiment, the crushing assembly includes a first motor fixedly connected to the crushing housing, a first spur gear fixedly connected to the output end of the first motor via a shaft, and a second spur gear meshing with one side of the first spur gear. The second spur gear is fixedly connected to the transmission shaft, and the first motor is used to drive the first spur gear to rotate.

[0008] In a preferred embodiment, the anti-clogging component includes a first bevel gear fixedly connected to the end of the drive shaft away from the second spur gear, two second bevel gears symmetrically meshed on both sides of the first bevel gear, a connecting shaft fixedly connected to the second bevel gears, and a connecting rod rotatably connected to the connecting shaft at one end. When the drive shaft rotates, the first bevel gear drives the two second bevel gears to rotate synchronously.

[0009] In a preferred embodiment, a ball joint is slidably connected to the other end of the connecting rod, a sliding sleeve is rotatably connected to the ball joint, and a striking head is fixedly connected to the end of the sliding sleeve near the filter screen.

[0010] In a preferred embodiment, a sliding column is slidably connected to the end of the sliding sleeve away from the filter screen, the sliding column is fixedly connected to the crushing shell, and a limit frame is movably connected between the two second bevel gears.

[0011] In a preferred embodiment, a mixing assembly is mounted on the mixing housing, and a mixing rod is connected to the output end of the mixing assembly. The mixing rod is rotatably connected to the mixing housing, and the mixing assembly is used to drive the mixing rod to rotate.

[0012] In a preferred embodiment, the mixing assembly includes a second motor fixedly connected to the mixing housing, a third spur gear fixedly connected to the output end of the second motor via a shaft, and a fourth spur gear meshing with one side of the third spur gear. The fourth spur gear is fixedly connected to the mixing rod, and the second motor is used to drive the third spur gear to rotate.

[0013] In a preferred embodiment, a discharge port is provided on the mixing shell, and an electric push rod is rotatably connected to the mixing shell. The output end of the electric push rod is rotatably connected to a sliding plate, and the sliding plate and the discharge port are slidably connected. The electric push rod is used to drive the sliding plate to move along the discharge port.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model achieves precise feeding of block and powder raw materials by setting up an integrated crushing shell and a mixing shell, and optimizing the diversion design of the top feed port and the side feed port. This avoids the energy waste caused by all materials entering the crushing stage indiscriminately. Furthermore, the effective impact surface formed by the hammer blades under centrifugal force can simultaneously impact and shear the materials, thereby obtaining a stable and efficient crushing effect. This allows each raw material to be processed through the most efficient path, ultimately achieving the dual goals of energy saving, consumption reduction, and improved overall production efficiency.

[0015] 2. This utility model simultaneously drives two systems, crushing and automatic anti-clogging, through a single power source, achieving a balance between high efficiency and low cost. Furthermore, by utilizing connecting rods, ball joint mechanisms, and striking heads, it generates continuous vibration force on the filter screen frame, which can automatically and in real time shake off the damp fine powder or fibrous material clogging the mesh during the crushing process. This maintains the effective permeability area of ​​the filter screen and avoids problems such as decreased crushing efficiency, poor material discharge, or even equipment overload caused by screen clogging, ensuring the continuity and stability of the crushing operation.

[0023] Refer to the instruction manual appendix Figures 1 to 6 A livestock feed uniform mixing device includes a support frame 1 and a crushing shell 2 and a mixing shell 3 fixedly connected to the support frame 1. The crushing shell 2 has a top feed inlet 201 and a side feed inlet 202. A drive shaft 5 is rotatably connected inside the crushing shell 2. A crushing component is installed on the crushing shell 2. The output end of the crushing component is connected to one end of the drive shaft 5. An anti-clogging component is installed on the other end of the drive shaft 5. The crushing component is used to drive the drive shaft 5 to rotate. A plurality of mounting discs 6 arranged in a linear array are fixedly connected to the drive shaft 5. A plurality of mounting rods 7 arranged in a circumferential array are fixedly connected to the mounting discs 6. A plurality of hammer blades 8 are rotatably connected to the mounting rods 7. A filter screen 9 is fixedly connected inside the crushing shell 2.

[0024] It should be noted that the device has two separate crushing and mixing areas, which are supported by the support frame 1. The crushing shell 2 and the mixing shell 3 are connected. The top feed inlet 201 of the crushing shell 2 is used to feed lumpy feed, and the side feed inlet 202 is used to feed powdered feed. The feed entering from the top feed inlet 201 falls onto the filter screen 9 and is crushed by the hammer blades 8 until it reaches the qualified particle size and then falls into the mixing shell 3 below. The feed entering from the side feed inlet 202 falls directly into the mixing shell 3.

[0025] It is worth noting that multiple mounting discs 6 are arranged equidistantly along the axial direction, serving as support and spacing. The mounting rod 7 passes through the corresponding holes on all mounting discs 6, and is locked at both ends with nuts, connecting multiple mounting discs 6 into a sturdy frame. The hammer blade 8 is hinged to the mounting rod 7. When the drive shaft 5 rotates, it drives the mounting discs 6, mounting rod 7 and hammer blade 8 to rotate together. The hammer blade 8 directly impacts and grinds the material, and under the action of centrifugal force, the hammer blade 8 spreads out radially, allowing the hammer blade 8 to swing when it encounters hard foreign objects, thus providing a certain degree of protection.

[0026] Another embodiment based on hammer blade 8: The straight cutting edge of hammer blade 8 is improved into a stepped cutting edge with three stages, that is, the thickness decreases stepwise from the mounting end to the striking end of hammer blade 8, forming multiple striking planes. The first thicker step is used for initial crushing and pre-cracking of large and hard materials, causing them to produce internal cracks. The subsequent thinner and sharper steps can finely crush the pre-cracked materials. This "division of labor" reduces the energy consumption of each strike and improves the overall crushing efficiency.

[0027] Another embodiment based on filter screen 9: the way filter screen 9 is fixedly installed on the crushing housing 2 can be improved to a detachable installation structure. Specifically, filter screen 9 can be installed on crushing housing 2 by mechanical snap-fit, which is convenient for subsequent replacement.

[0028] Refer to the instruction manual appendix Figure 3 The crushing assembly includes a first motor 401 fixedly connected to the crushing housing 2, a first spur gear 402 fixedly connected to the output end of the first motor 401 via a shaft, and a second spur gear 403 meshing with one side of the first spur gear 402. The second spur gear 403 is fixedly connected to the transmission shaft 5. The first motor 401 is used to drive the first spur gear 402 to rotate.

[0029] It should be noted that the first motor 401 is mounted on the crushing housing 2, and drives the transmission shaft 5 to rotate through the first spur gear 402 and the second spur gear 403. The first spur gear 402 and the second spur gear 403 are matched in size to achieve stable power transmission.

[0030] Refer to the instruction manual appendix Figure 5 The anti-clogging component includes a first bevel gear 1001 fixedly connected to the end of the drive shaft 5 away from the second spur gear 403, two second bevel gears 1002 symmetrically meshed on both sides of the first bevel gear 1001, a connecting shaft 1003 fixedly connected to the second bevel gears 1002, and a connecting rod 1004 rotatably connected to the connecting shaft 1003 at one end. When the drive shaft 5 rotates, the first bevel gear 1001 drives the two second bevel gears 1002 to rotate synchronously.

[0031] It should be noted that when the drive shaft 5 rotates, it drives the first bevel gear 1001 to rotate, which in turn drives the two symmetrically arranged second bevel gears 1002 to rotate synchronously. This symmetrical design balances the generated excitation force and avoids generating additional radial load on the main shaft. The entire mechanism only uses one power source of the drive shaft 5, without the need for additional drive, which is energy-saving and efficient. In addition, the size matching of the first bevel gear 1001 and the second bevel gear 1002 achieves stable power transmission.

[0032] Refer to the instruction manual appendix Figure 5The other end of the connecting rod 1004 is slidably connected to a ball head rod 11, and a sliding sleeve 12 is rotatably connected to the ball head rod 11. A striking head 13 is fixedly connected to one end of the sliding sleeve 12 near the filter screen 9.

[0033] It should be noted that the rotation of the second bevel gear 1002, through the connecting shaft 1003 and the connecting rod 1004, pushes the ball head rod 11 and the sliding sleeve 12 to slide axially back and forth, thereby driving the striking head 13 to periodically strike the frame of the filter screen 9. This continuous vibration can effectively shake off the fine powder clogging the screen holes, prevent the effective filtration area of ​​the screen from decreasing, and ensure the timely discharge of the crushed material and the stability of the crushing efficiency.

[0034] Refer to the instruction manual appendix Figure 5 The sliding sleeve 12 is slidably connected to a sliding column 14 at the end away from the filter screen 9. The sliding column 14 is fixedly connected to the crushing shell 2. A limit frame 15 is movably connected between the two second bevel gears 1002.

[0035] It should be noted that the sliding column 14 provides precise guidance and support for the movement of the sliding sleeve 12, ensuring the accurate movement trajectory of the striking head 13 and avoiding deviation. The limiting bracket 15 is used to constrain the relative position of the two second bevel gears 1002, maintain their correct meshing relationship with the first bevel gear 1001, and ensure the smoothness of power transmission and the long-term operational reliability of the mechanism.

[0036] Refer to the instruction manual appendix Figure 6 A mixing assembly is installed on the mixing housing 3. The output end of the mixing assembly is connected to a mixing rod 17. The mixing rod 17 is rotatably connected to the mixing housing 3. The mixing assembly is used to drive the mixing rod 17 to rotate.

[0037] It should be noted that the mixing component is responsible for fully and evenly mixing the different crushed raw materials and the powder fed in from the side inlet 202. The mixing rod 17 is equipped with spiral ribbon blades, which rotate under the drive of the mixing component, so that the material is both radially rolled and axially moved in the mixing shell 3, realizing three-dimensional convection, shearing and diffusion mixing, ensuring uniform distribution of trace components, avoiding feed grading and ensuring feed quality.

[0038] Refer to the instruction manual appendix Figure 6 The mixing assembly includes a second motor 1601 fixedly connected to the mixing housing 3, a third spur gear 1602 fixedly connected to the output end of the second motor 1601 via a shaft, and a fourth spur gear 1603 meshing with one side of the third spur gear 1602. The fourth spur gear 1603 is fixedly connected to the mixing rod 17. The second motor 1601 is used to drive the third spur gear 1602 to rotate.

[0039] It should be noted that the second motor 1601 is mounted on the mixing housing 3, and drives the mixing rod 17 to rotate through the third spur gear 1602 and the fourth spur gear 1603. The third spur gear 1602 and the fourth spur gear 1603 are matched in size to achieve stable power transmission.

[0040] Refer to the instruction manual appendix Figure 6 The mixing shell 3 has a discharge port 301. An electric push rod 18 is rotatably connected to the mixing shell 3. The output end of the electric push rod 18 is rotatably connected to a slide plate 19. The slide plate 19 and the discharge port 301 are slidably connected. The electric push rod 18 is used to drive the slide plate 19 to move along the discharge port 301.

[0041] It should be noted that the electric push rod 18 drives the slide plate 19 to slide along the discharge port 301, thereby opening and closing the discharge port 301. When the mixing reaches the set time, the electric push rod 18 is activated to open the discharge port 301 for material discharge. After the material discharge is completed, the port is closed to prepare for the next batch of production. The structure has good sealing performance, preventing dust from escaping or material from leaking during the mixing process.

[0042] Working principle: During operation, lumpy feed is fed into the top feed inlet 201 of the crushing shell 2 and falls onto the filter screen 9, while powdered feed enters the mixing shell 3 directly from the side feed inlet 202. The first motor 401 on the crushing shell 2 is started, driving the first spur gear 402 to rotate. The second spur gear 403 meshing with it drives the transmission shaft 5 to rotate. The transmission shaft 5 drives several mounting discs 6 to rotate, which in turn drives the mounting rods 7 and the hammers 8 hinged to them to rotate at high speed. Under centrifugal force, the hammers 8 spread out radially, impacting and grinding the lumpy feed. Material of the correct particle size falls through the filter screen 9 into the mixing shell 3 below. Simultaneously, the transmission shaft 5 drives the first bevel gear 1001 to rotate, driving two... The second bevel gear 1002 rotates synchronously. The second bevel gear 1002 converts the rotational motion into reciprocating motion through the connecting shaft 1003 and the connecting rod 1004, pushing the ball head rod 11 and the sliding sleeve 12 to slide axially along the guide of the sliding column 14. Finally, the striking head 13 periodically strikes the frame of the filter screen 9, shaking off the blockage. The feed falls into the mixing shell 3. The second motor 1601 is started, driving the third spur gear 1602 to rotate. The fourth spur gear 1603, which meshes with it, drives the mixing rod 17 to rotate, uniformly mixing the various feeds gathered there. After the mixing is completed, the electric push rod 18 is activated, driving the slide plate 19 to slide along the discharge port 301, opening the outlet, and the finished feed can be discharged, completing the entire working process.
