Description

Technical Field

[0001] This utility model relates to the field of compound feed pelleting technology, specifically to a pelleting device for compound feed. Background Technology

[0002] With the development of modern livestock farming on a large scale and intensified, compound feed, as an important carrier of animal nutrition, has its processing technology refined, which directly affects feed utilization and animal growth performance. The pelleting of compound feed is a key link in modern livestock production. Pellet feed has the advantages of convenient storage, efficient transportation, good palatability, and balanced nutrition.

[0003] Existing pelleting equipment for compound feed typically uses a single shaft and single blade to achieve unidirectional mixing motion when pelleting feed. When the single blade mixes clockwise, the feed tends to form a static area at the edge of the mixing drum. At the same time, the single blade cannot effectively break up larger particles and material clumps, which may affect the efficiency of subsequent pelleting. Therefore, we have introduced a pelleting equipment for compound feed. Utility Model Content

[0006] The granulation assembly includes a second motor, a second rotating shaft fixedly sleeved on the outer edge of the output shaft of the second motor, a bevel gear fixedly sleeved on the outer wall of the second rotating shaft, a third rotating shaft rotatably sleeved on the inner wall of the granulation cylinder, a bevel gear fixedly sleeved on the top of the third rotating shaft, a cutting blade fixedly sleeved on the bottom of the third rotating shaft, a spiral blade fixedly mounted on the outer wall of the third rotating shaft, one end of a connecting cylinder fixedly connected to the outer wall of the feeding pipe, an extrusion cylinder fixedly connected to the other end of the connecting cylinder, one end of a transmission cylinder fixedly connected to the bottom of the extrusion cylinder, a pressure head provided at the other end of the transmission cylinder, and a guide groove, an extrusion chamber, and a circular groove respectively opened on the inner wall of the pressure head.

[0007] As a preferred technical solution of this utility model: the stirring assembly includes a motor, a rotating shaft is fixedly sleeved on the outer edge of the output shaft of the motor, a gear is fixedly sleeved on the outer wall of the rotating shaft, a gear is meshed on the outer edge of the gear, a stirring rod is fixedly sleeved on the inner wall of the gear, a gear ring is meshed on the outer edge of the gear, a connecting rod is provided on the inner wall of the gear ring, a scraper is fixedly mounted on the outer wall of the connecting rod, a stirring blade is fixedly mounted on the outer wall of the rotating shaft, a cylinder is provided on the inner wall of the connecting rod, a ball and a spring are respectively provided in the inner cavity of the cylinder, and an arc groove is opened on the inner wall of the gear.

[0008] As a preferred technical solution of this utility model: the outer wall of the connecting rod is slidably fitted to the inner wall of the stirring cylinder. The connecting rod, scraper, cylinder, sphere and spring are considered as a set of movable components, and two of these movable components are symmetrically arranged around the first rotating shaft. The outer walls of the two scrapers are slidably fitted to the inner wall of the stirring cylinder. The second gear and stirring rod are considered as a set of movable components, and the number of these movable components is three, respectively arranged in a triangular shape on the outer edge of the first rotating shaft. The spring is located at the bottom of the sphere, with one end overlapping the inner wall of the cylinder and the other end overlapping the outer wall of the sphere. The diameter of the sphere is larger than the diameter of the opening of the cylinder, and the outer wall of the sphere is adapted to the inner wall of the arc-shaped groove.

[0009] As a preferred technical solution of this utility model: one end of the feeding pipe is connected to the discharge port of the mixing cylinder, and the other end is connected to the top of the production cylinder.

[0010] As a preferred technical solution of this utility model: the granulation component is regarded as a set of movable components, and the number of the movable components is two, which are arranged on both sides of the outer wall of the feeding pipe.

[0011] As a preferred technical solution of this utility model: the outer edge of the bevel gear teeth is interlocked with the outer edge of the bevel gear teeth, the outer wall of the cutting blade is slidably fitted to the bottom of the pressure head, and there are several circular grooves, each of which is connected to the inner wall of the circular groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This pelleting equipment for compound feed, through the counterclockwise rotation of three gears driven by gear one and the clockwise rotation of the mixing blade driven by the rotating shaft one, achieves counterclockwise circumferential mixing of the mixing rod by the rotation and revolution of gear two, which in turn generates convection with the clockwise mixing blade in the center. This breaks down and stratifies larger particles before pelleting. At the same time, the branched design of the extrusion cylinder and the transmission cylinder on both sides of the feeding pipe allows the feed to be branched and then driven by the spiral blades, pressure head, and guide groove in conjunction with the circular groove. This achieves stable conveying and dual-path pelleting of the feed, as well as continuous extrusion and cutting, thereby effectively improving the feed pelleting capacity and production efficiency of the equipment.

[0014] 2. This pelleting equipment for compound feed uses a connecting rod and scraper that slide along the inner wall of the mixing drum with the toothed ring. The scraper removes feed residue adhering to the inner wall of the mixing drum in real time, allowing the feed residue on the inner wall of the mixing drum to flow back to the central mixing area for remixing. This avoids the waste of raw materials caused by residue on the inner wall in existing equipment. At the same time, the connecting rod utilizes the elastic cooperation of springs and balls to achieve convenient and quick disassembly of the connection between the connecting rod and the toothed ring. This allows for easy maintenance by replacing the scraper without disassembling the mixing drum. Thus, it effectively cleans sticky materials while avoiding equipment wear caused by rigid contact, thereby extending the service life of the equipment. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1 - Figure 7 A pelleting device for compound feed includes a support frame 1, a pelleting cylinder 2 at the top of the support frame 1, a mixing cylinder 3 at the top of the pelleting cylinder 2, a feed inlet 9 at the top of the mixing cylinder 3, a discharge cylinder 7 at the bottom of the pelleting cylinder 2, a mixing assembly 4 in the inner cavity of the mixing cylinder 3, a feeding pipe 5 at the bottom of the mixing cylinder 3, a pelleting assembly 6 in the inner cavity of the pelleting cylinder 2, and an inclined plate 8 fixedly mounted on the inner wall of the discharge cylinder 7.

[0027] The pelletizing assembly 6 includes a second motor 601, a second rotating shaft 602 fixedly sleeved on the outer edge of the output shaft of the second motor 601, a bevel gear 608 fixedly sleeved on the outer wall of the second rotating shaft 602, a third rotating shaft 603 rotatably sleeved on the inner wall of the pelletizing cylinder 2, a bevel gear 604 fixedly sleeved on the top of the third rotating shaft 603, a cutting blade 613 fixedly sleeved on the bottom of the third rotating shaft 603, a spiral blade 614 fixedly mounted on the outer wall of the third rotating shaft 603, a connecting cylinder 605 fixedly connected to the outer wall of the feeding pipe 5, an extrusion cylinder 606 fixedly connected to the other end of the connecting cylinder 605, a transmission cylinder 607 fixedly connected to the bottom of the extrusion cylinder 606, a pressure head 609 provided at the other end of the transmission cylinder 607, and a guide groove 610, an extrusion chamber 611 and a circular groove 612 respectively opened on the inner wall of the pressure head 609;

[0028] In the above structure, by setting up the production cylinder 2 and the mixing cylinder 3, the material is placed in the inner cavity of the mixing cylinder 3, and then the material is stirred by its stirring component 4. After the stirring is completed, the material will enter the inner cavity of the production cylinder 2 through the feeding pipe 5, and the granulation component 6 in the inner cavity of the production cylinder 2 will squeeze and cut it into granules, which will then fall into the discharge cylinder 7 through the inclined plate 8.

[0029] In a preferred embodiment: the stirring assembly 4 includes a motor 401, a rotating shaft 402 is fixedly sleeved on the outer edge of the output shaft of the motor 401, a gear 403 is fixedly sleeved on the outer wall of the rotating shaft 402, a gear 404 meshes with the outer edge of the gear 403, a stirring rod 405 is fixedly sleeved on the inner wall of the gear 404, a gear ring 406 meshes with the outer edge of the gear 404, a connecting rod 407 is provided on the inner wall of the gear ring 406, a scraper 408 is fixedly mounted on the outer wall of the connecting rod 407, a stirring blade 409 is fixedly mounted on the outer wall of the rotating shaft 402, a cylinder 410 is provided on the inner wall of the connecting rod 407, a ball 411 and a spring 412 are respectively provided in the inner cavity of the cylinder 410, and an arc groove 413 is opened on the inner wall of the gear 404.

[0030] In a preferred embodiment: the outer wall of the connecting rod 407 is slidably fitted against the inner wall of the stirring cylinder 3. The connecting rod 407, scraper 408, cylinder 410, sphere 411 and spring 412 are considered as a set of movable components, and there are two of each movable component symmetrically arranged around the first rotating shaft 402. The outer walls of the two scrapers 408 are slidably fitted against the inner wall of the stirring cylinder 3. The second gear 404 and stirring rod 405 are considered as a set of movable components, and there are three of these movable components, which are respectively arranged in a triangular shape on the outer edge of the first rotating shaft 402. The spring 412 is located at the bottom of the sphere 411, with one end overlapping the inner wall of the cylinder 410 and the other end overlapping the outer wall of the sphere 411. The diameter of the sphere 411 is larger than the diameter of the opening of the cylinder 410. The outer wall of the sphere 411 is adapted to the inner wall of the arc groove 413.

[0031] In the above structure, by configuring the connecting rod 407, scraper 408, cylinder 410, ball 411, and spring 412, the motor 401 is started by an external power supply. This causes the outer edge of the output shaft of the motor 401 to drive the rotating shaft 402 to rotate. Under the rotation of the rotating shaft 402, the gear 403 drives three gears 404 distributed on the outer edge of the gear 403 to rotate. When the three gears 404 rotate, their outer edges drive the gear ring 406 to move along the inner wall of the stirring cylinder 3. As the gears rotate, the three gears 404 rotate around the outer edge of the gear 403, causing the three stirring rods 405 to stir the material inside the mixing drum 3 counterclockwise under the drive of the three gears 404. At the same time, the stirring blades 409 stir the material clockwise under the drive of the rotating shaft 402, thereby achieving uniform stirring of the material inside the mixing drum 3. Then, the two scrapers 408, symmetrically arranged around the rotating shaft 402, are connected by the connecting rod 407 and the gear ring 4. Driven by 06, the material adhering to the inner wall of the mixing drum 3 will be scraped off along the inner wall direction. The scraped material will flow back to the central mixing area for mixing, thereby realizing the recycling of the material adhering to the inner wall of the mixing drum 3. At the same time, when the bevel gear 608 needs to be disassembled and replaced, the connecting rod 407 is moved longitudinally along the inner wall direction of the gear ring 406, so that the ball 411 will disengage from the arc groove 413 that it is in contact with under the movement of the connecting rod 407. The ball 411 will come into contact with the inner wall of the gear ring 406. When the ball 411 comes into contact with the inner wall of the gear ring 406, the ball 411 will drive the spring 412 to slide and compress towards the inner wall of the cylinder 410. After the ball 411 separates from the inner wall of the gear ring 406, the ball 411 will be reset and fixed to the opening of the cylinder 410 under the rebound of the spring 412. This completes the disassembly of the gear ring 406 and the connecting rod 407, making it easier to replace and repair the scraper 408.

[0032] In a preferred embodiment: one end of the feeding pipe 5 is connected to the outlet of the mixing drum 3, and the other end is connected to the top of the production drum 2;

[0033] In the above structure, by setting the feeding pipe 5, the material in the inner cavity of the mixing drum 3 will be transferred to the inner cavity of the production drum 2 through the feeding pipe 5 after the mixing is completed for the next stage of production.

[0034] In a preferred embodiment: the pelletizing component 6 is regarded as a set of movable components, and the number of the movable components is two respectively, which are arranged on both sides of the outer wall of the feeding pipe 5;

[0035] In the above structure, by setting the granulation component 6, the granulation components 6 are set on both sides of the outer wall of the feeding pipe 5, and the materials that have been stirred are processed through the branches of the feeding pipe 5, thereby improving the material production efficiency of the production cylinder 2.

[0036] In a preferred embodiment: the outer edge of the teeth of the bevel gear 608 is interlocked with the outer edge of the teeth of the bevel gear 604, the outer wall of the cutting blade 613 is slidably attached to the bottom of the pressure head 609, and there are several circular grooves 612, and the several circular grooves 612 are respectively connected to the inner wall of the circular groove 612.

[0037] In the above structure, by setting the bevel gear 608, bevel gear 604, cutting blade 613 and circular groove 612, the bevel gear 608, under the rotation of the rotating shaft 602, engages with the outer edge of the bevel gear 604, causing it to rotate and drive the bevel gear 604 to rotate, thereby realizing the transmission of the cutting blade 613 and the spiral blade 614. At the same time, after the material is squeezed and transmitted to the inner cavity of the pressure head 609, the material passes through the guide groove 610 into the inner cavity of the extrusion chamber 611. Under the extrusion and compression of the material, the sealed inner cavity of the extrusion chamber 611 is squeezed out through several circular grooves 612, thus completing the preparation work before the material is granulated.

[0038] Working principle: First, compound feed ingredients are fed into the inner cavity of the mixing drum 3 through the feed inlet 9. Then, the motor 401 is started by connecting an external power source. The rotating shaft 402 rotates under the drive of the outer edge of the motor 401. This rotating shaft 402 drives the gear 403 to rotate clockwise. The outer edge of the gear 403 meshes with the three outer gears 404 to rotate counterclockwise. The outer edges of the three outer gears 404 mesh with the gear ring 406, causing the gear ring 406 to rotate clockwise along its inner wall. At the same time, the stirring rod 405 rotates counterclockwise with the gear 404 and revolves around the gear 403 to form a counterclockwise circumferential stirring. The stirring blade 409 forms a central stirring under the clockwise drive of the rotating shaft 402, forming a multi-directional convection mixing with the stirring rod 405, thereby ensuring that the feed is evenly mixed. Meanwhile, when the gear ring 406 drives the two sets of stacked connecting rods 407 to slide along the inner wall of the mixing drum 3, the scraper 408 will scrape off the feed adhering to the inner wall of the mixing drum 3 and return it to the mixing center area, thereby avoiding waste of feed raw materials.

[0039] After the feed in the inner cavity of the mixing drum 3 is mixed, it will simultaneously enter the inner cavities of the connecting drum 605 and the extrusion drum 606 on both sides through the branch of the feeding pipe 5. The motor 601 is then started by an external power source, causing the rotating shaft 602 to rotate under the drive of its outer edge. This rotating shaft 602 drives the bevel gear 608 to rotate and mesh with the bevel gear 604. The rotating shaft 603, driven by the bevel gear 604, rotates clockwise, causing the spiral blades 614 to rotate. The feed inside the extrusion cylinder 606 is fed into the extrusion chamber 611 of the pressure head 609 via the transfer cylinder 607 and the guide groove 610. Under the thrust of the hand-operated spiral blade 614, the feed in the extrusion chamber 611 is extruded into strips through several circular grooves 612 penetrating the pressure head 609, thus completing the initial shaping. At the same time, the cutting blade 613 rotates synchronously with the rotating shaft 603, so that the outer wall of the cutting blade 613 slides against the bottom of the pressure head 609, and then the extruded feed strips are cut into particles of a set length.

[0040] The pelleted feed falls from the bottom of the production cylinder 2 into the discharge cylinder 7, and the inclined plate 8 on the inner wall of the discharge cylinder 7 guides the pellets to slide down the cylinder wall, thus completing the pelleting of the feed.

[0041] Simultaneously, when removing and replacing the bevel gear 608, the motor 401 is turned off, stopping the operation of the inner cavity of the mixing drum 3. This causes the longitudinal moving connecting rod 407 to slide along the inner wall of the gear ring 406, disengaging the ball 411 from the gear 403. This releases the connection between the connecting rod 407 and the gear ring 406, allowing the ball 411 to contact the inner wall of the gear ring 406. This, in turn, compresses the circular groove 612. After the ball 411 separates from the inner wall of the gear ring 406, it is reset and fixed to the opening of the cylinder 410 by the spring 412. This completes the disassembly of the gear ring 406 and the connecting rod 407, making it easier to replace and repair the scraper 408.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
