Description

Technical Field

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

[0002] In the process of pig feed processing, the purpose of feed grinding is to increase the surface area of ​​the feed and adjust the particle size, thereby increasing the surface area, improving palatability, and helping to improve digestibility and better absorb the nutrients in the feed. Due to the wide variety of feed types and the different toughness of various feeds, some are difficult to grind. Existing pig feed grinding equipment has difficulty grinding tough feeds when stirring and grinding them.

[0003] Chinese patent discloses a preliminary grinding device for producing pig feed (authorization announcement number CN217725801U). The patented technology involves: a first motor driving a rotating rod to rotate, which in turn drives the blades to rotate. Under the rotation of the rotating rod and the blades, the feed inside the grinding device is initially ground while being stirred. When the first motor is started, a second motor is also started. The second motor drives the first grinding roller to rotate, which in turn drives the drive gear to rotate. The drive gear drives the driven gear to rotate, which in turn drives the second grinding roller to rotate. Under the coordinated rotation of the first and second grinding rollers, the feed that has been ground once is ground a second time.

[0004] However, it has certain drawbacks: the crushed material is discharged directly regardless of particle size, which will cause unevenly crushed material (especially coarse particles or tough feed ingredients that have not been fully crushed) to be mixed into the final product, seriously affecting the particle size uniformity of the finished feed. The substandard coarse particles not only affect the uniformity of feed mixing and subsequent pelleting process, but also reduce the digestibility and absorption rate of pigs, thus affecting the feeding effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A crushing device for pig feed production includes a receiving box, a discharge pipe connected to the lower surface of the receiving box and communicating with the interior therein, and a crushing box connected to the upper surface of the receiving box and communicating with the interior therein, and a feed pipe connected to the upper surface of the crushing box and communicating with the interior therein, and a crushing mechanism is provided on the left side surface and inside of the crushing box.

[0008] The receiving box has a screening opening at the lower end of its left side surface, and a screening mechanism is provided inside the receiving box. The screening mechanism includes a screen plate, and a frame is fixedly connected to the front and rear edges and the right edge of the upper surface of the screen plate. A hinge block is rotatably connected to the left end of the front and rear edges of the screen plate. A shaking element is provided on the right side surface of the frame.

[0009] As a further improvement of this utility model: the crushing mechanism includes two motors, one at the front and one at the back, and a crushing roller is fixedly connected to the output end of each of the two motors.

[0011] As a further embodiment of this utility model: the lower end of the hinge block is fixed to the lower inner surface of the screening opening.

[0012] As a further embodiment of this utility model: the motor is fixedly connected to the left side surface of the crushing box, the crushing roller is located inside the crushing box, and the right end of the crushing roller is rotatably connected to the right side surface inside the crushing box.

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

[0015] This invention uses a second motor to drive a rotating plate to rotate, which in turn drives a sliding plate to reciprocate up and down within a sliding sleeve. A second hinge block, a sliding rod, and a sliding tube then link the frame and the screen plate, causing the screen plate to vibrate continuously around the hinge block's fulcrum, thus achieving dynamic screening of the pulverized material. This design effectively prevents screen clogging, significantly improves screening efficiency, ensures rapid separation of qualified fine powder and smooth discharge through the outlet pipe, and simultaneously drives substandard coarse material to move automatically in a directional direction and be discharged and recycled from the screening opening. This ensures uniform particle size in the final product, prevents incompletely pulverized feed from mixing in, and improves the quality of pig feed. Attached Figure Description

[0022] Feed pipe 4 is used for discharging raw materials for pig feed; discharge pipe 2 is used for discharging crushed materials.

[0023] The crushing roller 7 is rotatably connected to the inner right side surface of the crushing box 3 via a bearing. The outer ring of the bearing is embedded and fixed to the inner right side surface of the crushing box 3, and the right end of the crushing roller 7 is fixed to the inner ring of the bearing.

[0024] The crushing roller 7 includes a roller body and roller teeth uniformly fixed to it; viewed from left to right, the left crushing roller 7 rotates clockwise and the right crushing roller 7 rotates counterclockwise. The roller teeth of the two crushing rollers 7 can achieve precise interlocking when rotating, forming a dynamic shearing surface. The interlocking shearing of the teeth can generate concentrated shear stress.

[0025] exist Figure 1 , Figure 3 and Figure 4 In the middle section: A screening opening 8 is provided at the lower end of the left side surface of the receiving box 1, and a screening mechanism 9 is provided inside the receiving box 1. The screening mechanism 9 includes a screen plate 10. A frame 11 is fixedly connected to the front and rear edges and the right edge of the upper surface of the screen plate 10. A hinge block 12 is rotatably connected to the left end of the front and rear edges of the screen plate 10. The lower end of the hinge block 12 is fixedly connected to the lower inner surface of the screening opening 8. A shaking element 13 is provided on the right side surface of the frame 11. The shaking element 13 includes a C-shaped plate 14. The right end of the C-shaped plate 14 is fixedly connected to the right inner surface of the crushing box 3. A motor 15 is fixedly connected to the left inner surface of the C-shaped plate 14. The output end of the second motor 15 is fixedly connected to a rotating plate 16. The left side surface of the rotating plate 16 away from the second motor 15 is rotatably connected to a rotating plate 17. The right side surface of the rotating plate 17 away from the rotating plate 16 is rotatably connected to a sliding plate 18. The sliding plate 18 is movably sleeved with a sliding sleeve 19. The right end of the sliding sleeve 19 is fixedly connected to the right side surface of the inside of the crushing box 3. The left side surface of the sliding plate 18 away from the rotating plate 17 is symmetrically fixed with two hinge blocks 20 in the front-back direction. A sliding rod 21 is rotatably connected between the two hinge blocks 20. A sliding tube 22 is movably sleeved on the outside of the sliding rod 21. The left end of the sliding tube 22 is fixedly connected to the right side surface of the frame 11.

[0026] The sieve plate 10 has uniformly distributed sieve holes;

[0027] The sieve plate 10 is located directly below the crushing box 3. It is used to screen the crushed material, screen out the incompletely crushed material and discharge it through the screening opening 8.

[0028] The rotation of the first rotating plate 16 drives the slide plate 18 to move up and down repeatedly through the second rotating plate 17, which in turn drives the screen plate 10 to move up and down repeatedly through the frame 11, thus creating vibration, improving screening efficiency and ensuring that the completely crushed material passes through the screen plate 10 normally.

[0030] The frame 11 is used to prevent materials from falling directly from the front, back, and right sides of the screen plate 10 without being screened.

[0031] The working principle of this utility model is as follows: Pig feed raw materials enter the crushing box 3 through the feed pipe 4. Two motors 6 are started to drive the crushing rollers 7 connected to each other to rotate in opposite directions (the left crushing roller 7 rotates clockwise and the right crushing roller 7 rotates counterclockwise). The roller blades precisely interlock to form a dynamic shearing surface, which efficiently shears and crushes the falling raw materials. The crushed material falls onto the screen plate 10 in the receiving box 1 below. At the same time, motor 15 is started to drive the rotating plate 16 to rotate. The rotating plate 16 drives the sliding plate 18 to reciprocate up and down in the sliding sleeve 19 through the rotating plate 17. The sliding plate 18 then transmits the reciprocating motion to the frame 11 and the screen plate 10 through the hinge block 20, the sliding rod 21 and the sliding tube 22, so that the screen plate 10 vibrates continuously. The qualified fine powder passes through the screen plate 10 under the action of vibration and is discharged through the discharge pipe 2. The large particles that fail to pass through the screen plate 10 move to the left under the action of vibration and are finally discharged through the screening opening 8 for recycling or reprocessing.
