Abstract
Description
Technical Field
[0001] This utility model relates to the field of pig premix processing technology, and in particular to a raw material screening and impurity removal device for pig premix processing. Background Technology
[0002] Pig premix is a semi-finished feed product made by mixing trace components such as vitamins, minerals, amino acids, and drugs with carriers or diluents. The processing requires strict control over precision and uniformity to ensure its quality. During the production of pig premix, to ensure the particle size meets requirements, the raw materials often need to undergo a certain degree of sieving. This not only ensures that the particle size meets the requirements (usually passing through a 40-60 mesh sieve) to guarantee uniformity in subsequent mixing, but also separates impurities (such as stones, metal particles) and lumps from the raw materials, ensuring uniform particle size and avoiding affecting the mixing effect.
[0003] However, existing raw material screening devices have poor overall screening effect when in use. The large particles discharged are often mixed with many small particles, and the large particles generated during the screening process cannot be easily discharged. They need to be manually stopped and cleaned, which is cumbersome. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a raw material screening and impurity removal device for processing pig premix.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A raw material screening and impurity removal device for processing pig premix includes a processing table with a through groove running through its top outer wall. Guide rails are bolted to the outer walls of both sides of the top of the processing table located within the through groove. Two guide rollers are tactilely connected to the inner walls of each guide rail. A U-shaped enclosure is welded to the outer wall of one of the four guide rollers on opposite sides. A screening mesh is fixed to the bottom of the U-shaped enclosure by screws. A linkage rod is rotatably connected to the outer wall of the U-shaped enclosure parallel to the width of the processing table via a clamp. A fixing pin is rotatably inserted into the end of the linkage rod. The fixing pin is welded to a rotating wheel, and a rotating shaft is welded to the center of the rotating wheel. The rotating shaft is rotatably mounted on the top outer wall of the processing table. A first synchronous pulley is welded to the outer wall of the rotating shaft away from the rotating wheel. A synchronous belt meshes with the outer wall of the first synchronous pulley, and a second synchronous pulley meshes with the inner wall of the end of the synchronous belt. A servo motor is connected to the center of the second synchronous pulley via a coupling.
[0007] As a further improvement of this utility model: the guide rail is fixed along the inclined direction, and the inclined angle of the guide rail is 2°-6°.
[0008] As a further improvement of this utility model: a semi-cylindrical baffle is adhered to the top outer wall of the screening mesh plate near the U-shaped enclosure opening, and the length of the semi-cylindrical baffle is adapted to the width of the screening mesh plate.
[0009] As a further embodiment of this utility model: a brush roller is rotatably mounted on the top outer wall of the U-shaped enclosure above the semi-cylindrical baffle, and a geared motor is connected to one side outer wall of the brush roller via a coupling.
[0010] As a further embodiment of this utility model: the brush roller is located above the semi-cylindrical baffle, and the bottom brush of the brush roller is in contact with the top outer wall of the screening screen plate.
[0011] As a further improvement of this utility model: both the servo motor and the geared motor are connected to a switch via wires, and the switch is connected to an external power source.
[0012] Compared with the prior art, this utility model provides a raw material screening and impurity removal device for processing pig premix, which has the following beneficial effects:
[0013] 1. The raw material screening and impurity removal device designed in this paper sets the screening screen plate at an angle and uses a servo motor to drive the linkage rod to rotate back and forth continuously, thereby driving the screening screen plate to move continuously. This, combined with the gravity of the raw materials of pig premix, causes them to roll down, achieving rapid vibration and thus accelerating the separation effect.
[0014] 2. In this design, the raw material screening and impurity removal device can remove larger impurities and clumps that are concentrated on one side of the bottom semi-cylindrical baffle after the small particles have been screened and fallen off. This is achieved by using a slowly rotating brush roller to remove the larger impurities, thus achieving separation without stopping the machine and greatly improving the practicality of the impurity removal device.
[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example 1:
[0022] A raw material screening and impurity removal device for processing pig premix, in this embodiment, as follows: Figure 1-3 As shown, the processing table 1 includes a through groove 2 extending through its top outer wall. Guide rails 3 are bolted to both sides of the top of the processing table 1, and two guide rollers 4 are rotatably connected to the inner walls of each guide rail 3. A U-shaped enclosure 5 is welded to the outer wall of one of the four guide rollers 4 on opposite sides. A screening screen 6 is fixed to the bottom of the U-shaped enclosure 5 with screws. A linkage rod 7 is rotatably connected to the outer wall of the U-shaped enclosure 5 on the side parallel to the width of the processing table 1 via a clamp. The end of the linkage rod 7 is rotatably inserted into... A fixed pin 8 is connected, which is welded and fixed to a rotating wheel 9. A rotating shaft 10 is welded to the center of the rotating wheel 9. The rotating shaft 10 is rotatably mounted on the outer wall of the top of the processing table 1. A first synchronous pulley 11 is welded to the outer wall of the rotating shaft 10 away from the rotating wheel 9. A synchronous belt 12 is engaged with the outer wall of the first synchronous pulley 11. A second synchronous pulley 13 is engaged with the inner wall of the end of the synchronous belt 12. A servo motor 14 is connected to the center of the second synchronous pulley 13 through a coupling.
[0023] By tilting the screening screen plate 6 and using the servo motor 14 to drive the linkage rod 7 to rotate back and forth continuously, the screening screen plate 6 can be pulled and moved continuously. This, combined with the gravity of the raw materials of the pig premix, causes them to roll down, which can achieve rapid vibration and thus accelerate the separation effect.
[0024] The guide rail 3 is fixed along the inclined direction, and the inclination angle of the guide rail 3 is 2°-6°. A semi-cylindrical baffle 15 is glued to the top outer wall of the screening screen plate 6 near the notch of the U-shaped enclosure 5, and the length of the semi-cylindrical baffle 15 is adapted to the width of the screening screen plate 6.
[0025] A brush roller 16 is rotatably mounted on the top outer wall of the U-shaped enclosure 5 above the semi-cylindrical baffle 15, and a geared motor 17 is connected to one side outer wall of the brush roller 16 via a coupling.
[0026] After the small particles have been screened and fallen off, the larger particles and agglomerates are concentrated on one side of the bottom semi-cylindrical baffle 15. The larger particles are then pushed out by the slowly rotating brush roller 16, achieving separation without stopping the machine and greatly improving the practicality of the impurity removal device.
[0027] In this embodiment, the impurity removal device is first assembled. Then, the geared motor 17 and servo motor 14 are connected to an external power supply. The servo motor 14 is then started, driving the rotating wheel 9 to rotate continuously. This causes the linkage rod 7, which is mounted on one end of the fixed pin shaft 8, to rotate back and forth continuously. The linkage rod 7 pulls the U-shaped barrier 5 along the guide rail 3. The raw material to be screened and impurity removed is placed at the highest point of the screening screen plate 6. The raw material itself rolls down the screening screen plate 6 due to its own gravity. During the rolling process, the linkage rod 7 continuously pulls and accelerates, further accelerating the screening of the raw material. Smaller particles fall directly, while larger particles of impurities and clumps remain on one side of the semi-cylindrical baffle 15. Then, the geared motor 17 is started, driving the brush roller 16 to rotate continuously. Since the bottom of the brush roller 16 is in contact with the screening screen plate 6, it pushes the impurities and clumps away, achieving impurity separation and cleaning without stopping the machine. The operation is convenient.
[0028] Example 2:
[0029] A raw material screening and impurity removal device for processing pig premix, such as Figure 1-3 As shown, this embodiment makes the following additions based on embodiment 1: the brush roller 16 is located above the semi-cylindrical baffle 15, and the bottom brush of the brush roller 16 is in contact with the top outer wall of the screening screen plate 6. The servo motor 14 and the reduction motor 17 are both connected to a switch through wires, and the switch is connected to an external power supply.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
