Description

Technical Field

[0001] This utility model relates to the field of feed pelleting machines, specifically to a feed pelleting machine for poultry and livestock. Background Technology

[0002] Poultry and livestock feed is a specially formulated food for the nutritional supply of poultry (such as chickens, ducks, geese) and livestock (such as pigs, cattle, sheep). Its composition and ratio directly affect the growth rate, health status and quality of products (meat, eggs, milk, etc.) of animals.

[0003] Feed production and processing technologies include grinding, mixing, pelleting, and post-coating. Grinding reduces the particle size of raw materials to improve digestibility; mixing ensures the uniform distribution of trace components; pelleting includes hard pellets and extruded feed, with hard pellets being pressed using high-temperature steam and extruded feed being extruded using high temperature and high pressure; post-coating involves adding heat-sensitive components (such as vitamins) after pelleting.

[0004] In the pelleting process, feed ingredients need to be pressed into pellets. Feed pellet mills are key equipment for pressing pellets and are widely used in poultry and livestock feed production. Pelleted feed has advantages such as improved palatability, reduced waste, and convenient storage and transportation.

[0005] The working principle of a ring die pellet mill is to compress powder into pellets through the ring die holes using pressure rollers. It boasts high production capacity and produces pellets with good hardness, making it suitable for high-protein, high-energy feeds, such as poultry and livestock feed. Traditional pellet mills typically have fixed cutter installations, making it impossible to adjust the length according to the actual needs of the feed, resulting in low operational flexibility. Furthermore, they do not further crush and mix the raw materials before pelleting, nor do they introduce steam to soften and condition the materials, thereby improving pelleting efficiency. Utility Model Content

[0006] To address the technical problems of traditional pellet mills where the cutter is mostly fixed and cannot be adjusted to the required length of the feed, resulting in low flexibility, and where the raw materials are not further crushed, mixed, and softened with steam before pelleting to improve pelleting efficiency, this invention provides a pellet mill for poultry and livestock feed.

[0026] A pellet mill for poultry and livestock feed includes a set of support platforms 1, with a ring die 2 rotatably mounted between the support platforms 1. A geared motor 11 is mounted on the outer wall of both the support platform 1 and the outer wall of the mixing tank 4 via a mounting bracket. One side of the outer plane of the ring die 2 is fixedly connected to the output shaft of the geared motor 11, and the other side of the outer plane of the ring die 2 is connected to the bottom end of a conveying pipe 5 via a rotary bearing 12. Starting the geared motor 11 drives the ring die 2 to rotate along the rotary bearing 12, and the rotational speed of the ring die 2 can be adjusted by adjusting the reduction mechanism in the geared motor 11.

[0027] A set of pressure rollers 3 are rotatably arranged inside the ring die 2. Several particle outlet holes 13 are provided through the arc-shaped side wall of the ring die 2. A certain gap is provided between the outer wall of one end of the pressure rollers 3 and the inner wall of the ring die 2. When the ring die 2 rotates, the raw material passes through the gap. At the same time, the contact between the raw material and the pressure rollers 3 causes the pressure rollers 3 to rotate as well. When the pressure rollers 3 rotate, the raw material is pressed out from the particle outlet holes 13.

[0028] A feed trough 8 is provided through the top wall of the mixing tank 4. A set of crushing rollers 10 is rotatably arranged on the inner wall of the feed trough 8. Each set of crushing rollers 10 includes a crushing shaft 29 rotatably arranged between the inner walls of the feed trough 8. Crushing blades 30 are fixedly arranged on the outer wall of the crushing shaft 29. The crushing blades 30 in the two crushing shafts 29 are arranged alternately. One end of each crushing shaft 29 passes through the side wall of the feed trough 8 and is fixedly arranged with a gear 31. The two gears 31 are meshed with each other, and the central shaft of one of the gears 31 is fixedly connected to the output shaft of the reduction motor 11, which is mounted on the outer wall of the feed trough 8 through a mounting bracket.

[0029] The prepared raw materials are placed into the feed trough 8, and the reduction motor 11 is started at the same time to drive the gear 31 to rotate. Since the two gears 31 are meshed with each other, they rotate in opposite directions. When rotating, the staggered crushing blades 30 also rotate in opposite directions, so that the raw materials placed between the crushing rollers 10 can be further crushed, making the raw materials finer.

[0030] A mixing tank 4 is fixedly installed on the top of a set of support platforms 1. The bottom of the mixing tank 4 is connected to the inside of the ring mold 2 through a material conveying pipe 5. The bottom wall of the mixing tank 4 has a structure that is low in the middle and high at both ends. The top of the material conveying pipe 5 is fixedly installed inside the bottom wall of the mixing tank 4 at the low middle position. A stirring rod 6 is rotatably installed inside the mixing tank 4. The outer wall of the material conveying pipe 5 is fixedly connected to the inner side wall of the support platform 1. The stirring rod 6 includes a stirring shaft 24 installed on the output shaft of the reduction motor 11. Stirring paddles 25 of different lengths are fixedly installed on the outer wall of the stirring shaft 24.

[0031] After being crushed, the raw materials fall into the mixing tank 4 below. The reduction motor 11 is started, which drives the mixing shaft 24 to rotate, and then drives the mixing paddle 25 to rotate, thus agitating the raw materials. The bottom wall of the mixing tank 4 has a structure that is low in the middle and high at both ends, which makes it convenient for the raw materials to enter from the top of the conveying pipe 5.

[0032] A heating box 7 is provided on the side wall of the mixing tank 4. The heating box 7 is connected to the mixing tank 4 through an air supply pipe 9.

An air pump 27 is installed on the air supply pipe 9. An exhaust pipe 28 is fixedly installed through the outer wall of the mixing tank 4.

[0033] Before mixing, hot water is added to the heating box 7 through the water inlet pipe, and then the electric heating rod 26 is powered on. After the water is heated into steam, the air pump 27 is turned on so that the hot steam can be transported to the mixing box 4 through the air delivery pipe 9. After mixing with the raw materials, the subsequent pelletizing effect can be better, and the excess gas is discharged from the exhaust pipe 28.

[0034] Two sets of pelletizing structures 14 are symmetrically arranged on the outside of the ring die 2. Each set of pelletizing structures 14 includes a set of vertical plates 17 fixedly arranged on the inner side wall of the support platform 1.

A guide groove 19 parallel to the threaded screw 15 is fixedly arranged on the inner side wall of the support platform 1 where the vertical plate 17 is located.

[0035] When the length of the pellets needs to be adjusted, crank the handle 18 to rotate the threaded screw 15. Since each pelletizing structure 14 includes a threaded screw 15, and a pelletizing blade 16 is movably mounted on the outer wall of the threaded screw 15, the rotation of the threaded screw 15 can cause the pelletizing blade 16 to move left and right along the guide groove 19 to adjust the position of the pelletizing blade 16.

[0036] The pelletizing blade 16 includes a fixedly mounted handle 20 and a pelletizing blade 21. One end of the handle 20 is threadedly connected to the outer wall of the threaded screw 15, and its end can move inside the guide groove 19. An alignment indicator line 22 is provided on the outer wall of the handle 20, and a scale line 23 is fixedly provided on the inner wall of the support platform 1. The alignment indicator line 22 can be aligned with any scale of the scale line 23 to indicate the pelletizing length of the pelletizing blade 21.

[0037] When the blade handle 20 moves left and right along the guide groove 19 and the threaded screw 15, the distance can be adjusted according to any of the required scales of the alignment indicator line 22 and the scale line 23. The distance between the uncut blade 21 and the particle outlet hole 13 is shown by the scale line 23, and the cutting length can be adjusted according to the distance.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
