Description

Technical Field

[0001] This utility model relates to the field of feed processing, and in particular to a feed pellet mill. Background Technology

[0002] In the field of feed processing, the pelleting process has a direct impact on the quality, storability and feeding effect of feed. The material crushing treatment before pelleting is a key prerequisite for ensuring pelleting quality. The fineness and uniformity of material crushing will significantly affect the mixing uniformity, conditioning effect and the hardness, density and nutritional stability of the final pellet feed during the subsequent pelleting process.

[0003] Currently, feed processing companies mostly rely on existing conventional crushing equipment to crush materials before pelleting. However, the original design of such crushing equipment is mostly adapted to the material processing needs of food and other fields. Its crushing principle and structural characteristics are not fully adapted to the diverse and complex material characteristics in feed production.

[0004] Specifically, this manifests as follows: incomplete material crushing, with some coarse fibrous materials or raw materials with high hardness being difficult to effectively break down, leaving behind large particles; at the same time, the crushed material particles are uneven in size, with significant differences in coarseness and fineness. This not only leads to poor material flowability during subsequent pelleting, affecting the feeding stability of the pellet mill, but also causes the produced pellet feed to have quality problems such as being loose and easily broken, reducing the overall quality of the feed product and failing to meet the demands of modern feed production for efficient and high-quality processing. Utility Model Content

[0005] The purpose of this utility model is to provide a feed pellet mill in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a feed pellet mill, comprising a mixing and crushing mechanism and a base below it, wherein a conveying and extrusion mechanism is installed at the lower part of the mixing and crushing mechanism, a feeding mechanism is installed at the upper part of the base, and a servo motor is installed inside the base to drive the conveying and extrusion mechanism and the mixing and crushing mechanism to work together.

[0007] The mixing and crushing mechanism includes a mixing drum and a fixed frame installed inside it. A rotating disk is rotatably installed on the upper side of the fixed frame, and a gear box is rotatably installed on the upper side of the rotating disk. Two crushing toothed rollers rotate in opposite directions on both sides of the gear box.

[0008] As a further description of the above technical solution: the feeding mechanism includes a sleeve one fixedly installed on the top of the base, a feeding hopper is installed through one side of the sleeve one, and an inclined plate is installed on the inner side of the sleeve one, with the slope direction of the inclined plate being set on the side close to the feeding hopper.

[0009] As a further description of the above technical solution: the conveying and extrusion mechanism includes a second sleeve fixedly installed between the first sleeve and the mixing cylinder. The second sleeve is connected to the mixing cylinder. The bottom end of the second sleeve has several discharge holes. The second sleeve is rotatably mounted with a connecting shaft fixedly connected to the output shaft of the servo motor. The outer side of the connecting shaft is fitted with an auger blade that is compatible with the inner side of the second sleeve.

[0010] As a further description of the above technical solution: the feeding mechanism also includes a fixed seat that is installed through the outside of the first sleeve, and a toothed disc that is rotatably installed at the bottom end of the second sleeve. The top end of the toothed disc has several alignment holes that intersect with several discharge holes on the second sleeve. The second toothed disc that meshes with the first toothed disc is rotatably installed inside the fixed seat.

[0011] As a further description of the above technical solution: two fixed plates are fixedly installed on both sides of the gear box and fixedly connected to the inner side of the stirring drum. Several meshing bevel gears are rotatably installed at the bottom end of the inner side and the two ends of the inner vertical direction of the gear box. Fixed shafts are fixedly connected to the inner shaft center of the two crushing tooth rollers. The two fixed shafts are fixedly connected to the rotation shaft of the corresponding bevel gear. The output shaft of the connecting shaft is fixedly connected to the rotation shaft of the corresponding bevel gear.

[0012] As a further description of the above technical solution: the outer side of the connecting shaft is fixedly connected to the axis of the rotating disk, and several counterweights are installed at equal intervals on the outer sides of both fixed shafts.

[0013] As a further description of the above technical solution: a number of filter plates are installed in a ring array between the stirring cylinder and the fixed frame, and a number of inclined scrapers are installed in a ring array on the outer side of the rotating disk.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] The two crushing toothed rollers are driven by a servo motor to rotate in opposite directions at high speed to crush and mix the material in the mixing drum. During this process, the servo motor can also drive the rotating disk to make the material in the mixing drum move in a circular motion. In this way, the material in the mixing drum can continuously change the contact angle during the continuous rotation, so as to fully collide and shear with the two high-speed rotating crushing toothed rollers in multiple directions, greatly improving the crushing uniformity and crushing efficiency of the material.

[0016] As the two crushing toothed rollers rotate, the counterweights inside generate centrifugal force due to the rotation, creating continuous inertial pressure. This pressure, like a road roller crushing materials, forces the material between the crushing toothed rollers and the mixing drum of the material chamber to be crushed. This causes the material to be subjected to continuous extrusion force while being sheared at high speed, further enhancing the crushing effect of the material particles. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 - Figure 5As shown, the present invention provides a feed pellet mill, including a mixing and crushing mechanism 4 and a base 1 below it. A conveying and extruding mechanism 3 is installed at the lower part of the mixing and crushing mechanism 4, and a feeding mechanism 2 is installed at the upper part of the base 1. A servo motor 11 is installed inside the base 1 to drive the conveying and extruding mechanism 3 and the mixing and crushing mechanism 4 to work together.

[0026] In actual use, this solution uses a mixing and crushing mechanism 4 to crush the material. The crushed material is then conveyed and extruded into pellets by a conveying and extrusion mechanism 3. The size of the feed pellets is adjusted by the cooperation of the feeding mechanism 2 and the conveying and extrusion mechanism 3. The size of the feed pellets is precisely adjusted by changing the extrusion orifice diameter to meet the different needs of different breeding species and different growth stages for feed pellet size, thereby improving the palatability and feeding effect of the feed.

[0027] Specifically, the mixing and crushing mechanism 4 includes a mixing drum 41 and a fixed frame 42 installed inside it. A rotating disk 43 is rotatably installed on the upper side of the fixed frame 42. A gear box 44 is rotatably installed on the upper side of the rotating disk 43. Two crushing toothed rollers 47 rotate in opposite directions on both sides of the gear box 44.

[0028] Two fixed plates 441, which are fixedly connected to the inner side of the mixing drum 41, are fixedly installed on both sides of the gear box 44. Several meshing bevel gears 45 are rotatably installed at the bottom and vertical ends of the inner side of the gear box 44. Fixed shafts 46 are fixedly connected to the inner shaft center of the two crushing rollers 47. The two fixed shafts 46 are fixedly connected to the rotation shaft of the corresponding bevel gear 45. The output shaft of the connecting shaft 32 is fixedly connected to the rotation shaft of the corresponding bevel gear 45.

[0029] The outer side of the connecting shaft 32 is fixedly connected to the axis of the rotating disk 43, and several counterweights 461 are installed at equal intervals on the outer sides of the two fixed shafts 46.

[0030] The servo motor 11 drives several meshing bevel gears 45 to rotate, which in turn drives two crushing toothed rollers 47 to rotate in opposite directions at high speed to crush and stir the material in the mixing drum 41. During this process, the servo motor 11 can also drive the rotating disk 43 to make the material in the mixing drum 41 move in a circular motion. In this way, the material in the mixing drum 41 can continuously change the contact angle during the continuous rotation, so as to fully form multi-directional collision and shearing with the two high-speed rotating crushing toothed rollers 47.

[0031] When the two crushing toothed rollers 47 rotate, the counterweight 461 inside them generates a continuous inertial pressure due to the centrifugal force generated by the rotation. This pressure is like a road roller crushing materials, forcing the material between the crushing toothed rollers 47 of the crushing component and the mixing drum 41 of the material chamber to be crushed, so that the material is subjected to continuous extrusion force while being sheared at high speed.

[0032] Furthermore, a number of filter plates 48 are installed in a ring array between the stirring cylinder 41 and the fixed frame 42, and a number of inclined scrapers 431 are installed in a ring array on the outer side of the rotating disk 43.

[0033] The crushed material falls downward through the filter holes of the filter plate 48. When the rotating disk 43 rotates, it drives several inclined scrapers 431 to rotate, thereby shoveling the material that has not passed through the filter plate 48 upward and crushing it.

[0034] Specifically, the conveying and extrusion mechanism 3 includes a second sleeve 31 fixedly installed between the first sleeve 21 and the mixing drum 41. The second sleeve 31 is connected to the mixing drum 41. Several discharge holes are opened through the bottom end of the second sleeve 31. A connecting shaft 32 fixedly connected to the output shaft of the servo motor 11 is rotatably installed on the shaft of the second sleeve 31. An auger blade 33 adapted to the inner side of the second sleeve 31 is installed on the outside of the connecting shaft 32.

[0035] After being crushed, the material falls into the sleeve 31 after passing through the filter plate 48. The output shaft of the servo motor 11 drives the rotating disk 43 and the bevel gear 45 through the connecting shaft 32, and at the same time drives the auger blade 33 to rotate. As the auger blade 33 rotates and conveys the material downward, it squeezes the material in the sleeve 31, so that the material is squeezed and shaped through the discharge hole at the bottom of the sleeve 31.

[0036] Furthermore, the feeding mechanism 2 includes a sleeve 21 fixedly installed at the top of the base 1. A feeding hopper 23 is installed through one side of the sleeve 21, and a sloping plate 22 is installed inside the sleeve 21. The slope direction of the sloping plate 22 is set on the side close to the feeding hopper 23.

[0037] The feeding mechanism 2 also includes a fixed seat 25 that is installed through the outside of the sleeve 21, and a rotatably mounted gear disk 24 that is rotatably mounted at the bottom of the sleeve 31. The top of the gear disk 24 has several alignment holes that intersect with several discharge holes on the sleeve 31. The fixed seat 25 has a gear disk 26 that meshes with the gear disk 24.

[0038] The extruded feed pellets fall onto the inclined plate 22 and are discharged outward through the feed hopper 23 along the slope of the inclined plate 22.

[0039] Rotating the second gear disk 26 causes the first gear disk 24, which meshes with it, to rotate, so that the alignment hole on the first gear disk 24 intersects with the discharge port on the second sleeve 31, changing the size of the discharge port on the second sleeve 31, thereby adjusting the size of the feed pellets.

[0040] This solution involves pouring the material into the mixing and crushing mechanism 4 to crush it. The crushed material is then conveyed and extruded into pellets by the conveying and extrusion mechanism 3. The size of the feed pellets is adjusted by the cooperation of the feeding mechanism 2 and the conveying and extrusion mechanism 3. The size of the feed pellets is precisely adjusted by changing the extrusion orifice diameter to meet the differentiated needs of different breeding species and different growth stages for feed pellet size.

[0041] 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.
