Description

Technical Field

[0001] This invention relates to the field of pig feed processing technology, and in particular to a uniform mixing and stirring device and method for pig feed processing. Background Technology

[0002] Pig feed is a compound feed made by scientifically combining and processing various single feed ingredients according to the physiological and nutritional needs and growth performance goals of pigs at different growth stages. In pig feed production, uniform mixing is the core prerequisite for ensuring feed quality, breeding efficiency, and pig safety. This is to ensure that the various nutrients and additives in the feed are evenly distributed and meet the feed mixing requirements.

[0003] During the mixing process of pig feed, liquid ingredients such as oils and molasses are added. Due to the high viscosity and tendency of oils and molasses to agglomerate, they tend to form oil or molasses clumps of varying sizes when mixed with powdered base ingredients. If these viscous clumps are too large, they will sink to the bottom of the mixing device. Furthermore, large clumps are not easily driven by the paddles to participate in the mixing process, making it difficult to achieve thorough mixing of the feed. On the other hand, the oil and molasses clumps formed during the mixing process can also adhere to the outside of the paddles due to their viscous adsorption, thereby weakening the paddles' ability to push, shear, and disperse the material and reducing the overall mixing efficiency of the paddles. In addition, when there is a lot of material adhering to the surface of the existing paddles, manual stopping and repeated adjustment of the paddle direction are required for cleaning, which is time-consuming and inefficient.

[0004] Therefore, this application provides a uniform mixing and stirring device and method for pig feed processing to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a uniform mixing and stirring device and method for pig feed processing, so as to solve the problem that when viscous liquid raw materials are added during pig feed mixing, they easily agglomerate with powdered base raw materials to form oil or honey clumps. Large clumps will sink to the bottom of the mixing device and are not easy to mix fully. In addition, these clumps will also be adsorbed on the outside of the blades, which are not easy to clean and reduce the overall mixing efficiency of the blades.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A uniform mixing and stirring device for pig feed processing includes a mixing body and a spraying mechanism installed at the upper part of the mixing body. The mixing body includes a mixing chamber and a discharge chamber. Two fixed plates are installed on the inner wall of the mixing chamber. Two connecting rollers are symmetrically and rotatably installed between the two fixed plates. Gears are fixed on the outer side of the inner section of the right fixed plate of each of the two connecting rollers. The two gears mesh with each other. The right end of the front connecting roller is rotatably connected to the inner wall of the mixing chamber through a motor. Multiple blades are symmetrically and laterally arranged on the outer side of each of the two connecting rollers. Two discharge plates are symmetrically and rotatably connected to the bottom of the mixing chamber through a rotating shaft. The two discharge plates are movably connected to the inner wall of the discharge chamber through two hydraulic drive mechanisms. A crushing component is provided in the cavity at the lower end of each of the two discharge plates. The crushing component is used to crush lumps generated during the mixing process. A scraping component is provided between the crushing component, the connecting rollers and the blades. The scraping component is used to clean the surface of the blades.

[0007] Optionally, the crushing assembly includes a connecting column, which is rotatably connected to the lower cavity of the unloading plate by a motor. A spiral groove is provided on the outer side of the connecting column, and a connecting rod is slidably connected inside the spiral groove. Multiple sliding strips are fixedly connected to the top of the connecting rod. The multiple sliding strips slide vertically through the groove at the top of the unloading plate. A saw blade is fixedly connected to the top of each of the multiple sliding strips. A lever is fixedly connected to the top of the end of the saw blade away from the connecting column. Multiple saw blades are fixedly fixed at equal intervals in the groove at the top of the unloading plate.

[0008] Optionally, multiple saw blades one and multiple saw blades two are arranged longitudinally in the groove at the top of the unloading plate, and the saw blades one and two are arranged at intervals.

[0009] Optionally, the scraping assembly includes two scrapers and a square plate that are slidably installed in the upper and lower grooves of the blade. The square plate is slidably installed inside the connecting roller. One end of the scraper is fixedly connected to a sliding column. The sliding column passes through an opening on the outside of the connecting roller and is connected to an inclined groove. The inclined groove is opened on the front and rear walls of the square plate. One end of the square plate is fixedly connected to a circular plate. The lower end of the circular plate abuts against a lever. The circular plate is fixedly connected to a second circular plate by a spring and a telescopic rod. The second circular plate abuts against the inner wall of the mixing chamber.

[0010] Optionally, a rotating ball is movably connected to the end of the lever that abuts against the circular plate. The rotating ball is used to maintain a stable contact with the circular plate as it rotates with the square plate.

[0011] Optionally, the number of the plurality of sloping grooves corresponds to the number of blades, the number of openings on the outer side of the connecting roller corresponds to the number of sloping grooves, and the openings on the outer side of the connecting roller correspond to the inclination direction of the sloping grooves.

[0012] Optionally, the sliding stroke generated by the spiral groove driving the connecting rod corresponds to the sliding stroke generated by the inclined groove driving the sliding column.

[0013] Optionally, the method includes the following steps: S1: Solid raw materials are put into the mixing chamber, and liquid feed raw materials are sprayed through the spraying mechanism. The two connecting rollers drive the paddles to rotate and mix the solid and liquid feed raw materials in the mixing chamber. S2: The spiral groove on the outside of the connecting column rotates in both directions, driving the saw blade to reciprocate in a straight line. The reciprocating saw blade one and the saw blade two fixed in the groove of the unloading plate form a dynamic shearing structure, which efficiently crushes the feed clumps. S3: The saw blade moves back and forth with the slide bar, pushing the round plate and the square plate to move synchronously. The inclined groove converts the axial movement of the square plate into the oblique sliding of the slide bar, which drives the scraper to scrape off the adhering substances on the surface of the blade. S4: The hydraulic drive mechanism pushes the two discharge plates at the bottom of the mixing bin to rotate downward around the axis, discharging the evenly mixed feed into the discharge bin and completing the feed mixing process.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, the motor drives the connecting column to rotate in both directions through the crushing component. At this time, the rotational motion of the connecting column is converted into the linear reciprocating motion of the connecting rod through the spiral groove, which in turn drives the saw blade one to move synchronously. The moving saw blade one and the fixed saw blade two form a dynamic shearing structure to crush the feed clumps falling into the top of the discharge plate, improve the mixing efficiency, and ensure the uniformity of the mixing of materials in the mixing chamber.

[0015] In the above scheme, the scraping component, through the reciprocating movement of the saw blade, pushes the circular plate to move, thereby driving the square plate inside the connecting roller to move synchronously. At this time, the sloping groove converts the axial movement of the square plate into the oblique sliding of the scraper along the sloping groove direction. Therefore, the scraper scrapes off the initial coagulated clumps attached to the outside of the blade in real time, realizing the self-maintenance function of mixing and cleaning at the same time, so as to maintain the mixing efficiency of the blade.

[0018] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention. Example

[0019] Please see Figures 1 to 12This invention provides a technical solution: a uniform mixing and stirring device for pig feed processing, comprising a mixing body 1 and a spraying mechanism 2 installed at the upper end of the mixing body 1. The mixing body 1 includes a mixing chamber 11 and a discharge chamber 12. Two fixed plates 3 are installed on the inner wall of the mixing chamber 11, and two connecting rollers 5 are symmetrically and rotatably installed between the two fixed plates 3. Gears 4 are fixed on the outer side of the inner section of the right fixed plate 3 of the two connecting rollers 5, and the two gears 4 mesh with each other. The right end of the front connecting roller 5 is rotatably connected to the inner wall of the mixing chamber 11 through a motor. Multiple blades 6 are symmetrically and laterally arranged on the outer side of the two connecting rollers 5. Two discharge plates 7 are symmetrically and rotatably connected to the bottom end of the mixing chamber 11 through a rotating shaft. The two discharge plates 7 are movably connected to the inner wall of the discharge chamber 12 through two hydraulic drive mechanisms 8. The lower cavities of the two discharge plates 7 are hollow. Each chamber is equipped with a crushing component 9, which is used to crush lumps generated during the mixing process. A scraping component 10 is installed between the crushing component 9, the connecting roller 5, and the blade 6. The scraping component 10 is used to clean the surface of the blade 6. When mixing pig feed, the feed raw materials are first put into the mixing chamber 11. The spraying mechanism 2 is started to spray the liquid raw materials evenly into the chamber. Then the motor is started to drive the front connecting roller 5 to rotate. Through two meshing gears 4, the rear connecting roller 5 rotates synchronously in opposite directions, thereby driving the blade 6 to rotate in opposite directions to achieve uniform stirring and mixing of the feed raw materials. During this process, after the mixing is completed, the hydraulic drive mechanism 8 is activated to push the discharge plate 7 to rotate downward around the axis, opening the bottom outlet of the mixing chamber 11, so that the uniformly mixed feed falls into the discharge chamber 12 below through the discharge plate 7, completing the unloading.

[0020] The crushing assembly 9 includes a connecting column 91, which is rotatably connected to the lower cavity of the discharge plate 7 via a motor. A spiral groove 92 is formed on the outer side of the connecting column 91, and a connecting rod 93 is slidably connected inside the spiral groove 92. Multiple sliding strips 94 are fixedly connected to the top of the connecting rod 93, and these sliding strips 94 slide vertically through a groove at the top of the discharge plate 7. A saw blade 95 is fixedly connected to the top of each sliding strip 94. A lever 96 is fixedly connected to the top of the end of the middle saw blade 95 furthest from the connecting column 91. Multiple saw blades 97 are equidistantly fixed within the groove at the top of the discharge plate 7. During the mixing process, when the feed ingredients are mixed... When clumps accumulate in the bin 11 and may form lumps, the motor of the crushing component 9 is started. The motor rotates in both directions, causing the connecting column 91 to rotate in both directions. Since the connecting rod 93 is slidably connected in the spiral groove 92 on the outside of the connecting column 91, the rotational motion of the connecting column 91 is converted into the linear reciprocating motion of the connecting rod 93 through the spiral groove 92. This, in turn, drives multiple slide bars 94 to slide back and forth synchronously along the direction of the groove at the top of the discharge plate 7. The saw blade 95 at the top of the slide bar 94 then moves periodically relative to the fixed saw blade 97, forming a dynamic shearing structure to efficiently crush the feed lumps falling into the top of the discharge plate 7 and improve the mixing efficiency.

[0021] Multiple saw blades 95 and multiple saw blades 97 are arranged longitudinally in the groove at the top of the unloading plate 7, with saw blades 95 and 97 spaced apart. Since saw blades 95 and 97 are arranged longitudinally and spaced apart in the groove, when saw blade 95 moves, its teeth will repeatedly penetrate the gaps between adjacent saw blades 97, forming a shearing structure similar to interlocking comb teeth. Once the feed clump falls into this area, it will be repeatedly cut and squeezed by the saw teeth of saw blades 95 and 97, thus being broken into finer particles.

[0022] The scraping assembly 10 includes two scrapers 104 and a square plate 101, which are slidably mounted in the upper and lower grooves of the paddle 6. The square plate 101 is slidably mounted inside the connecting roller 5. One end of the scraper 104 is fixedly connected to a sliding column 103, which passes through an opening on the outside of the connecting roller 5 and is connected to an inclined groove 102. The inclined groove 102 is formed on the front and rear walls of the square plate 101. One end of the square plate 101 is fixedly connected to a circular plate 105, the lower end of which abuts against a lever 96. The circular plate 105 is fixedly connected to a circular plate 106 via a spring and a telescopic rod. The circular plate 106 abuts against the inner wall of the mixing chamber 11. During the mixing process, the paddle 6 rotates as a whole to mix and stir the feed ingredients. Due to the addition of liquid ingredients, part of the mixture... Materials tend to adhere to the surface of the blade 6, forming an agglomerate layer that affects mixing efficiency. At this time, multiple saw blades 95 reciprocate under the drive of the spiral groove 92. Their movement drives the lever 96 to move synchronously. The lever 96 periodically reciprocates and pushes the circular plate 105 to move, which in turn drives the square plate 101 inside the connecting roller 5 to move synchronously. Under the action of the inclined groove 102 on the outside of the square plate 101 and the connecting roller 5, the axial movement of the square plate 101 is converted into the sliding of the scraper 104 along the direction of the inclined groove 102. Therefore, the scraper 104 scrapes off the initial agglomerates attached to the outside of the blade 6 in real time, realizing the self-maintenance function of mixing and cleaning at the same time. When the lever 96 returns to its original position with the saw blades 95, the spring pushes the circular plate 105 and the square plate 101 to reset.

[0023] A rotating ball is movably connected to the end of the lever 96 that abuts against the circular plate 105. The rotating ball is used to maintain a stable contact with the circular plate 105 as the circular plate 105 rotates with the square plate 101. Through the rolling contact of the rotating ball, the frictional resistance between the lever 96 and the circular plate 105 is reduced, and the ball adapts to the change in the circumferential position of the circular plate 105 when the connecting roller 5 rotates. No matter what circumferential angle the circular plate 105 is at, the rotating ball can adapt to its surface profile through rolling and always maintain effective contact with the circular plate 105.

[0024] The number of inclined grooves 102 corresponds to the number of blades 6, the number of openings on the outer side of the connecting roller 5 corresponds to the number of inclined grooves 102, and the openings on the outer side of the connecting roller 5 correspond to the inclination direction of the inclined grooves 102.

[0025] The sliding stroke generated by the spiral groove 92 driving the connecting rod 93 corresponds to the sliding stroke generated by the inclined groove 102 driving the sliding column 103, so that while the crushing component 9 performs one saw blade-95 crushing reciprocating action, the scraping component 10 simultaneously completes one scraper 104 cleaning cycle.

[0026] As one embodiment of the present invention, the method includes the following steps: S1: Solid raw materials are put into the mixing chamber 11, and liquid feed raw materials are sprayed through the spraying mechanism 2. The two connecting rollers 5 drive the paddles 6 to rotate and mix the solid and liquid feed raw materials in the mixing chamber 11. S2: The spiral groove 92 on the outside of the connecting column 91 rotates in both directions, which drives the saw blade 95 to move linearly back and forth. The reciprocating saw blade 95 and the saw blade 97 fixed in the groove of the unloading plate 7 form a dynamic shearing structure to efficiently crush the feed clumps. S3: The saw blade 95 moves back and forth with the slide bar 94, pushing the round plate 105 and the square plate 101 to move synchronously. The inclined groove 102 converts the axial movement of the square plate 101 into the oblique sliding of the slide bar 103, which drives the scraper 104 to scrape off the adhering substances on the surface of the blade 6. S4: The hydraulic drive mechanism 8 pushes the two discharge plates 7 at the bottom of the mixing chamber 11 to rotate downward around the axis, discharging the evenly mixed feed into the discharge chamber 12, thus completing the feed mixing process.

[0027] The working principle of the technical solution provided by this invention is as follows: Solid pig feed ingredients are fed into the mixing chamber 11 of the mixer body 1. The spraying mechanism 2 installed at the upper part of the mixer body 1 is started to spray liquid feed ingredients evenly into the mixing chamber 11, completing the feeding and pretreatment of solid and liquid ingredients. The motor is started, and the motor drives the front connecting roller 5 to rotate. Through the transmission of two meshing gears 4 on the inner side of the right fixed plate 3, the rear connecting roller 5 and the front connecting roller 5 are rotated in opposite directions, thereby driving multiple blades 6 on the outer side of the two connecting rollers 5 to rotate in opposite directions, stirring the solid and liquid feed ingredients in the mixing chamber 11, and completing the initial uniform mixing of the ingredients. The motor in the lower cavity of the discharge plate 7 is started. The motor rotates forward and backward, driving the connecting column 91 to rotate forward and backward. The spiral groove 92 on the outside of the connecting column 91 converts the rotational motion into the linear reciprocating motion of the connecting rod 93. The connecting rod 93 drives multiple slide bars 94 at the top to slide back and forth along the groove at the top of the discharge plate 7. The saw blade 95 at the top of the slide bar 94 and the saw blade 97 fixed in the groove of the discharge plate 7 form a dynamic shearing structure, which efficiently crushes the feed clumps that fall into the top of the discharge plate 7 during the mixing process, thereby improving the mixing efficiency. When the lever 96 at the top of the middle saw blade 95 reciprocates synchronously with the slide bar 94, the ball at the end of the lever 96 stably abuts against the circular plate 105, pushing the circular plate 105 to move. The circular plate 105 drives the square plate 101 inside the connecting roller 5 to move axially synchronously. At this time, the inclined groove 102 converts the axial movement of the square plate 101 into the oblique sliding of the slide column 103. Therefore, the slide column 103 drives the scraper 104 to slide along the grooves on the upper and lower surfaces of the blade 6, which removes the initial agglomerates attached to the surfaces of both sides of the blade 6. The block is scraped in both directions. When the lever 96 returns to its original position with the saw blade 95, the spring between the circular plate 105 and the square plate 101 pushes the circular plate 105 and the square plate 101 to reset, completing one cleaning of the blade 6. While the crushing component 9 completes one reciprocating crushing action of the saw blade 95, the scraping component 10 simultaneously completes one cleaning cycle of the scraper 104 on the outside of the blade 6, effectively solving the problems of feed clumping and material adhesion to the blade 6 during the mixing process, ensuring mixing efficiency and material uniformity. Once the feed ingredients are mixed, the two hydraulic drive mechanisms 8 on the inner wall of the unloading hopper 12 are activated. The hydraulic drive mechanisms 8 are activated, pushing the two unloading plates 7 at the bottom of the mixing hopper 11 to rotate downwards around the axis, opening the opening at the bottom of the mixing hopper 11. At this time, the evenly mixed feed falls into the unloading hopper 12 through the unloading plates 7, completing the mixing and stirring operation of the entire pig feed.
