Description

Technical Field

[0001] The invention relates to the technical field of pig feed processing, in particular to a raw material crushing device for pig feed processing. Background Art

[0002] Cables are an indispensable and important part of modern communications, electricity, electronic equipment and other fields. Their quality directly affects power transmission, data transmission and the safety and stability of equipment. The performance of cables depends not only on the selection and processing technology of their conductors, but also on the quality of the outer coating material. The coating of the cable not only protects the conductor, but also provides multiple functions such as electrical insulation, mechanical strength, waterproofing, anti-corrosion, and fire resistance. Therefore, as one of the core equipment in cable manufacturing, the cable coating molding device undertakes the key task of evenly and accurately coating different protective or insulating materials on the outer layer of the cable conductor; For example, in the prior art, there is a cable processing device with publication number CN108672040B, which is convenient for cable core overmolding. The device can swing up and down with the main crushing knife on both sides of the main shaft under the drive of two adjustment motors through two auxiliary crushing branches, so as to roughly crush the pig feed raw materials. After the rough crushing, the raw materials enter the alternating main crushing ring and the auxiliary crushing ring for fine crushing, realizing the continuous crushing function of the pig feed raw materials.

At this time, the first rotating shaft rotates in cooperation with the first synchronous belt and the first synchronous wheel to drive the eccentric block to rotate, and the eccentric block rotates and repeatedly hits the convex block, and the screen plate is hit and cooperates with the first spring and the guide column to form a vibrating screen effect, so as to screen out larger gravel and debris inside the raw material, thereby ensuring the purity of the raw material; 2. In the present invention, when the raw materials are crushed, the lock between the positioning block and the guide slide rod is released by rotating the bolt, and then the positioning block is moved to the position of the crushing roller of the required crushing size, and the bolt is rotated again to fix the positioning block. Subsequently, during the raw material crushing process, the first rotating shaft cooperates with the first bevel gear and the second bevel gear to drive the screw to rotate, and the rotation of the screw drives the limit block to descend until it reaches the position of the positioning block. At this time, the positioning block cannot continue to move, and the first rotating shaft continues to rotate to drive the first conical block to rotate. The first conical block is squeezed by the second conical block and moves toward the inside of the first rotating shaft to avoid motion interference. At this time, the first guide plate is located at the adjusted positioning block position, that is, the raw material is guided to the crushing roller position of the required crushing specification.

[0015] 3. The present invention is provided with three groups of crushing rollers, which are suitable for crushing raw materials into different specifications. The first material guide plate is moved to different crushing roller positions through the material guide regulating mechanism, so that the raw materials are crushed by different crushing rollers to obtain raw materials of required specifications, and the raw materials are driven by the third auger to be discharged through the discharge port, so as to quickly obtain the required raw materials.

[0016] To summarize, the present invention relies on the material guide regulating mechanism to control the first auger to rotate to form material discharge, and at the same time drives the screen plate to form a vibrating screening effect, so as to ensure the purity of the raw materials inside. The screened raw materials fall above the first material guide plate, and the first material guide plate is moved to the position of the crushing roller of the required specifications through the material guide regulating mechanism. Finally, the raw materials are crushed to the corresponding specifications through the crushing roller of the required specifications, so as to quickly obtain the raw materials of the required specifications, and the scope of application is wider and the raw materials are purer.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1:

[0021] This embodiment is designed to address the problem in the prior art that when crushing raw materials, it is impossible to screen out larger raw materials and debris that may exist inside the raw materials, making it difficult to ensure the uniformity and purity of the raw materials. At the same time, after crushing, the raw materials cannot be crushed to the corresponding specifications according to the required crushing specifications, and the overall function is relatively single.

[0022] like Figure 1-7 As shown, a raw material crushing device for pig feed processing includes a control box 1, a storage box 2 is fixed on the upper surface of the control box 1, and two protection boxes 4 are symmetrically fixed on both sides of the control box 1, a material guide regulating mechanism 12 is installed between the control box 1 and the protection box 4, and the material guide regulating mechanism 12 includes a first rotating shaft 9 rotatably connected, a first bevel gear 25 is sleeved at the position of the outer layer of the first rotating shaft 9 corresponding to the protection box 4, and one side of the first rotating shaft 9 passes through the control box 1 and extends to one side. The first motor 3 is fixed to the outside of the protection box 4, and a second bevel gear 26 is arranged below the first bevel gear 25; A screw rod 11 rotatably connected to the inside of the protective box 4 is fixed to the bottom of the second bevel gear 26, and the outer layer of the screw rod 11 is sleeved with a limit block 23, and a guide slide rod 10 fixed to the inside of the protective box 4 is provided on one side of the screw rod 11. The guide slide rod 10 has a semicircular structure. When the first auger 13 does not rotate, the raw material cannot be lowered. The outer layer of the guide slide rod 10 is sleeved with a positioning block 22, and the outer layer of the guide slide rod 10 is equidistantly provided with three screw holes 24, and one side of the positioning block 22 is rotatably connected with a bolt 7 adapted to the positioning block 22, and a through groove 5 is provided on one side of the protective box 4 at the position corresponding to the bolt 7; A first guide plate 16 is fixed between the two limit blocks 23. The first guide plate 16 is inclined with respect to the horizontal direction. The screened raw materials are introduced into the crushing box 8 through the inclination design. A baffle plate 20 is fixed on the top of one side of the first guide plate 16. A connecting plate 19 is slidably connected inside the baffle plate 20. A plurality of first springs 21 are equidistantly fixed inside the baffle plate 20 at the bottom of the connecting plate 19. A plurality of second cone blocks 42 are equidistantly fixed inside the first bevel gear 25. The baffle plate 20 and the connecting plate 19 are used to block other crushing inlets, thereby avoiding the waste of raw materials. At the same time, the connecting plate 19 can be retracted into the baffle plate 20 by using the first spring 21 in the initial state. When the baffle plate 20 is lowered, the connecting plate 19 is raised by the reaction force of the first spring 21, thereby sufficiently blocking other crushing inlets. Two first conical blocks 40 are symmetrically slidably connected at the positions of the second conical blocks 42 on both sides of the interior of the first rotating shaft 9. A third spring 41 is fixed to one end of the first conical block 40 inside the first rotating shaft 9; A second rotating shaft 32 rotatably connected to the inside of the control box 1 is provided between the first rotating shaft 9 and the first guide plate 16. Two first synchronous wheels 27 are symmetrically sleeved on both sides of the outer layers of the first rotating shaft 9 and the second rotating shaft 32. The two first synchronous wheels 27 on the same side are rotatably connected via a first synchronous belt 33. An eccentric block 30 is sleeved at the middle position of the first rotating shaft 9. A sieve plate 17 is provided at a position above the eccentric block 30 in the control box 1. The sieve plate 17 is inclined with respect to the horizontal direction. The inclination of the sieve plate 17 is designed so that when the sieve plate 17 vibrates, the sieved debris will move in the direction of the inclination and be discharged through the notch. A notch is provided at the rear end of the control box 1 at the position corresponding to the sieve plate 17. Four guide columns 28 are symmetrically fixed on both sides of the sieve plate 17, the guide columns 28 are slidably connected to the inside of the control box 1, and the outer layer of the guide columns 28 is sleeved with a second spring 29 fixed between the control box 1 and the protrusion 31. A protrusion 31 is fixed at the position of the eccentric block 30 at the bottom of the sieve plate 17, and a second material guide plate 18 is fixed at the middle position of the first rotating shaft 9 at the bottom of the storage box 2. The inside of the second material guide plate 18 is rotatably connected to the first auger 13 sleeved on the outside of the first rotating shaft 9.

[0023] When the raw material is crushed, the first motor 3 is started to drive the first rotating shaft 9 to rotate, and the rotation of the first rotating shaft 9 drives the first auger 13 to rotate, thereby driving the raw material to fall into the control box 1. At this time, the first rotating shaft 9 rotates to cooperate with the first synchronous wheel 27 and the first synchronous belt 33 to drive the second rotating shaft 32 to rotate, and the rotation of the second rotating shaft 32 drives the eccentric block 30 to repeatedly hit the protrusion 31, and at the same time cooperates with the second spring 29 to drive the screen plate 17 to repeatedly rise and fall to form a vibrating screen effect, so as to screen out larger particles and debris inside the raw material; The first rotating shaft (9) rotates and cooperates with the first bevel gear 25 and the second bevel gear 26 to drive the screw rod 11 to rotate. The rotation of the screw rod 11 drives the limit block 23 to rise and fall. Before this, the bolt 7 is rotated to release the engagement state between the positioning block 22 and the screw hole 24. Then the positioning block 22 is slid to the position of the crushing roller 34 of the required specification. The limit block 23 is then interfered with as it is lifted and lowered to the position of the positioning block 22. When the limit block 23 cannot move due to the interference, the screw rod 11 cannot rotate at this time, that is, the second bevel gear 26 acts in the opposite direction on the first bevel gear 25 to prevent it from rotating. At this time, the first conical block 40 inside the first rotating shaft 9 is squeezed by the second conical block 42 due to continuous rotation and moves toward the inside of the first rotating shaft 9. Therefore, while the first rotating shaft 9 continues to rotate, it will not be interfered with due to the inability of the first bevel gear 25 to rotate. Thus, the screened raw materials fall onto the upper surface of the first guide plate 16, and as the first guide plate 16 descends to the position of the crushing roller 34 of the required specification, they enter the crushing box 8 for crushing.

[0024] Embodiment 2:

[0025] This embodiment aims to address the problem in the prior art that the specifications of the crushing rollers are relatively single when crushing raw materials, and the raw materials cannot be crushed to corresponding specifications according to the required crushing specifications.

[0026] like Figure 8-9 As shown, the embodiment is a raw material crushing device for pig feed processing, and a crushing box 8 is fixed at the front end of the control box 1, and three third guide plates 35 are fixed at equal distances inside the crushing box 8, and a crushing assembly 14 is installed inside the third guide plate 35, and the crushing assembly 14 includes a second auger 15 rotatably connected to the inside of the third guide plate 35, the second auger 15 is a semicircular structure, and the crushing roller 34 can completely block the entrance above the second auger 15, that is, the raw materials crushed by the crushing roller 34 will enter the inside of the second auger 15, one side of the second auger 15 penetrates and extends to the outside of the crushing box 8, and a stepper motor is fixed, and three groups of crushing rollers 34 rotatably connected to the inside of the crushing box 8 are arranged above the three second augers 15, and the crushing specifications of the three crushing rollers 34 are different. A discharge port 6 is opened at the position corresponding to the second auger 15 on one side of the crushing box 8; A gear 39 is fixed to one side of the crushing roller 34, and a second synchronous wheel 36 is fixed to one side of the crushing roller 34 and extends through and extends to the outside of the crushing box 8. Adjacent second synchronous wheels 36 are rotationally connected by a second synchronous belt 38, and a second motor 37 is fixed to one side of one of the second synchronous wheels 36.

[0027] The raw materials introduced into the crushing box 8 enter into the crushing roller 34 of the required specifications, and the second motor 37 is started to cooperate with the second synchronous wheel 36 and the second synchronous belt 38 to rotate, thereby driving the crushing roller 34 to rotate. The sieved raw materials are crushed by the rotation of the crushing roller 34, and the second auger 15 is driven to rotate by the stepper motor. The rotation of the second auger 15 drives the crushed raw materials to be discharged through the discharge port 6, thereby classifying the crushed raw materials of different specifications, which is more convenient for collection and subsequent processing.

[0028] Working process and principle of the present invention: Step 1: When crushing the raw materials, start the first motor 3 to drive the first rotating shaft 9 to rotate, and the rotation of the first rotating shaft 9 drives the first auger 13 to rotate, thereby driving the raw materials to fall into the control box 1. At this time, the first rotating shaft 9 rotates to cooperate with the first synchronous wheel 27 and the first synchronous belt 33 to drive the second rotating shaft 32 to rotate, and the rotation of the second rotating shaft 32 drives the eccentric block 30 to repeatedly hit the protrusion 31, and at the same time cooperates with the second spring 29 to drive the screen plate 17 to repeatedly rise and fall to form a vibrating screen effect, so as to screen out larger particles and debris inside the raw materials; The first rotating shaft (9) rotates and cooperates with the first bevel gear 25 and the second bevel gear 26 to drive the screw rod 11 to rotate. The rotation of the screw rod 11 drives the limit block 23 to rise and fall. Before this, the bolt 7 is rotated to release the engagement state between the positioning block 22 and the screw hole 24. Then the positioning block 22 is slid to the position of the crushing roller 34 of the required specification. The limit block 23 is then interfered with as it is lifted and lowered to the position of the positioning block 22. When the limit block 23 cannot move due to the interference, the screw rod 11 cannot rotate at this time, that is, the second bevel gear 26 acts in the opposite direction on the first bevel gear 25 to prevent it from rotating. At this time, the first conical block 40 inside the first rotating shaft 9 is squeezed by the second conical block 42 due to continuous rotation and moves toward the inside of the first rotating shaft 9. Therefore, while the first rotating shaft 9 continues to rotate, it will not be interfered with due to the inability of the first bevel gear 25 to rotate. Thus, the screened raw materials fall onto the upper surface of the first guide plate 16, and as the first guide plate 16 descends to the position of the crushing roller 34 of the required specification, they then enter the crushing box 8 for crushing; Step 2: The raw materials introduced into the crushing box 8 enter the crushing roller 34 of the required specifications, and the second motor 37 is started to cooperate with the second synchronous wheel 36 and the second synchronous belt 38 to rotate, thereby driving the crushing roller 34 to rotate. The sieved raw materials are crushed by the rotation of the crushing roller 34, and the second auger 15 is driven by a stepper motor to rotate. The second auger 15 rotates and drives the crushed raw materials to be discharged through the discharge port 6, thereby classifying the crushed raw materials of different specifications, which is more convenient for collection and subsequent processing.

[0029] In summary, the material guiding and regulating mechanism 12 is used to control the feeding of raw materials and screen and guide the raw materials at the same time. The position of the positioning block 22 is independently controlled to control the specifications of the crushing roller 34 corresponding to the first material guiding plate 16, so that the raw materials are crushed to the required specifications, and the crushed raw materials of different specifications are classified and collected to facilitate subsequent collection, storage and processing.

[0030] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
