[0001] The invention relates to the technical field of grinding devices, in particular to a feed additive raw material grinding device. Background Art

[0002] Feed additives are commonly used raw materials in the modern feed industry, which can enhance the nutritional value of basic feed, improve animal production performance and ensure animal health. The production process of feed additives involves grinding the raw materials.

[0003] Generally speaking, the raw materials of feed additives are ground by grinding devices, but the grinding efficiency of most grinding devices is low, resulting in insufficient manufacturing efficiency of the grinding workshop and affecting production efficiency.

[0004] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Summary of the invention

[0005] Based on this, it is necessary to provide a feed additive raw material grinding device that can improve the grinding efficiency of the feed additive raw materials in order to address the problems existing in the current feed additive raw material grinding device.

[0006] The above purpose is achieved through the following technical solutions:

[0007] A feed additive raw material grinding device, the feed additive raw material grinding device comprises a shell and a grinding body;

[0008] The shell has a receiving cavity inside, and has a feed port and a discharge port communicating with the receiving cavity. The grinding body is rotatably arranged in the receiving cavity, and the outer peripheral surface cooperates with the cavity side wall of the receiving cavity to form a grinding space, the grinding space is communicated with the feed port and the discharge port, and is used to grind feed additive raw materials. The outer peripheral surface of the grinding body is convexly provided with a plurality of guide bars at intervals, and the surfaces of two adjacent guide bars facing each other and the outer peripheral surface of the grinding body cooperate to form a guide channel;

[0009] The guide channel is spirally extended around the rotation center line of the grinding body, and the angle between the extension direction of the guide channel and the up-down direction tends to gradually increase. The guide channel is used to guide the feed additive raw material from the feed inlet to the discharge outlet.

[0010] Further, the guide channel includes a first channel and a second channel, one end of the first channel is connected to the feed port, one end of the second channel is connected to the other end of the first channel, and the other end is connected to the discharge port;

[0011] Wherein, the angle between the first channel and the up-down direction is smaller than the angle between the second channel and the up-down direction.

[0012] Furthermore, along the extension direction of the guide channel, the distance between two adjacent guide bars gradually decreases;

[0013] And / or, along the extension direction of the guide channel, the protruding length of each guide strip gradually decreases.

[0014] Furthermore, the grinding body is arranged in a conical shape and is gradually expanded from top to bottom.

[0015] Furthermore, the grinding bodies include at least two, and at least two of the grinding bodies are spaced apart and arranged in the receiving cavity;

[0016] The rotation directions of the two adjacent grinding bodies are consistent, and the guide bars of the two adjacent grinding bodies facing each other are arranged at an angle and cooperate to form a shearing structure, which is used to shear the feed additive raw materials.

[0017] Furthermore, it also includes at least two first driving members, both of which are installed on the shell, and one of the first driving members is transmission-connected to one of the grinding bodies to respectively drive the grinding bodies to rotate along the same rotation direction.

[0018] Furthermore, a first discharge channel and a second discharge channel are formed on the side wall of the receiving cavity, the first discharge channel extends along the circumference of the shell, and the second discharge channel extends in a top-to-bottom direction;

[0019] Wherein, the feed additive raw material grinding device also includes a baffle, which is covered at the opening of the first discharge channel and has a feed port connected to the first discharge channel.

[0020] Furthermore, it also includes a transmission belt and a second driving member, wherein the transmission belt is arranged in the first discharge channel, and includes a belt body and a plurality of push plates, wherein the plurality of push plates are arranged at intervals along the extension direction of the belt body, and the second driving member is installed on the housing and is in transmission connection with the belt body;

[0021] Wherein, under the drive of the second driving member, the belt body can rotate in the first discharge channel, so that the push plate can push the feed additive raw material from the first discharge channel to the second discharge channel.

[0022] Furthermore, the second driving member includes a driving motor and a connecting rod, the driving motor is drivingly connected to the connecting rod, and the connecting rod is threadedly connected to the belt body;

[0023] Wherein, the driving motor can drive the connecting rod to rotate, thereby driving the belt body to rotate in the first discharge channel.

[0024] Furthermore, the first discharge channel includes a discharge channel and a mounting channel, the discharge channel is communicated with the second discharge channel, and the mounting channel is communicated with the discharge channel. The belt body is embedded in the mounting channel and can rotate in the mounting channel;

[0025] Wherein, a plurality of push plates are located in the discharge channel so as to push the feed additive raw materials located in the discharge channel to the second discharge channel.

[0026] The beneficial effect of the present invention is that: by adopting the setting of the spiral guide channel, the feed additive raw material is limited and guided, so that the feed additive raw material has a spiral downward movement tendency. For example, when the grinding body rotates in the counterclockwise direction, it will drive the feed additive raw material before being ground and crushed to move synchronously in the counterclockwise direction. At this time, the shell rotates in the clockwise direction relative to the grinding body and the feed additive; therefore, the direction of the friction force applied to the feed additive raw material by the side wall of the grinding space constructed by the shell is determined by the movement direction of the shell relative to the feed additive, that is, the clockwise direction. As the shell and the grinding space rotate relative to each other, the friction force applied by the shell to the feed additive raw material will be greater than the hardness of the feed additive, so that the feed additive raw material can be ground and crushed, and the particle size will become smaller after grinding and crushing, and will be smaller than the size of the guide channel, that is, smaller than the spacing between two adjacent guide bars, so that the feed additive raw material with a small particle size will not be stuck in the guide channel, effectively avoiding the situation where the feed additive raw material stagnates in the guide channel and rotates counterclockwise with the grinding body. Then, although the feed additive raw material after being ground and crushed will still contact the shell under the action of centrifugal force, the friction between the feed additive raw material and the side wall of the grinding space is rolling friction, and the friction force is relatively small. Therefore, the feed additive raw material after being ground and crushed will still move downward in a clockwise spiral relative to the grinding body under the guidance of the guide channel under the action of its own gravity.

[0027] Moreover, the angle between the extension direction of the guide channel of the technical solution of the present invention and the up-down direction tends to gradually increase, so that the guide channel can gradually tend to be horizontal, that is, extend along the circumferential direction of the grinding body, so that the feed additive raw materials can be distributed in the guide channel along the circumferential direction in the form of gradually decreasing particle size and irregular shape after being ground, thereby effectively reducing the risk of the feed additive raw materials clogging the guide channel after being ground.

[0041] Please refer to Figure 1 , Figure 2 as well as Figure 5 The present invention proposes a feed additive raw material grinding device. In an embodiment of the present application, the feed additive raw material grinding device includes a shell 10 and a grinding body 20.

[0042] The housing 10 can be made of metal to have a strong structural strength, wherein the housing 10 has the function of carrying various components of the feed additive raw material grinding device. The housing 10 has a receiving cavity 11 inside, and the housing 10 has a feed inlet 12 and a discharge port 13 connected to the receiving cavity 11.

[0043] The grinding body 20 can be set in a conical shape, and the material of the grinding body 20 can be metal material, so as to have excellent wear resistance and corrosion resistance. The present invention does not impose specific restrictions on the shape and material of the grinding body 20. The grinding body 20 can be rotatably set in the receiving chamber 11, and the outer peripheral surface of the grinding body 20 and the cavity side wall of the receiving chamber 11 cooperate to form a grinding space 30. The grinding space 30 is connected with the feed port 12 and the discharge port 13, and is used to grind the feed additive raw material; it can be understood that the feed port 12 is used for the feed additive raw material to enter the grinding space 30. When the feed additive raw material is in the grinding space 30, it will be squeezed between the cavity side wall of the receiving chamber 11 and the outer peripheral surface of the grinding body 20 and crushed, so that the particles with larger particle size become particles with smaller particle size, so as to achieve the grinding effect, and then the ground particles will be discharged from the discharge port 13.

[0044] The outer circumference of the grinding body 20 is provided with a plurality of guide bars 21 at intervals. In some structural forms, the plurality of guide bars 21 can be an integral structure with the grinding body 20 to have a better connection strength and reduce the assembly steps of the two. The surfaces facing each other of the two adjacent guide bars 21 and the outer circumference of the grinding body 20 cooperate to form a guide channel 211. The guide channel 211 is arranged to extend spirally around the rotation center line of the grinding body 20, and the angle between the extension direction of the guide channel 211 and the up-down direction has a tendency to gradually increase. The guide channel 211 is used to guide the feed additive raw material from the feed inlet 12 to the discharge port 13. It can be understood that each guide bar 21 can be arranged in a spiral shape, so the guide channel 211 formed by two adjacent guide bars 21 and the grinding body 20 can be spiral.

[0045] The technical solution of the present invention adopts the setting of the spiral guide channel 211 to limit and guide the feed additive raw material, so that the feed additive raw material has a spiral downward movement tendency. For example, when the grinding body 20 rotates in the counterclockwise direction, it will drive the feed additive raw material before grinding and crushing to move synchronously in the counterclockwise direction. At this time, the shell 10 rotates in the clockwise direction relative to the grinding body 20 and the feed additive; therefore, at this time, the direction of the friction force applied to the feed additive raw material by the side wall of the grinding space 30 constructed by the shell 10 is determined by the movement direction of the shell 10 relative to the feed additive, that is, the clockwise direction. As the shell 10 and the grinding space 30 rotate relative to each other, the friction force applied by the shell 10 to the feed additive raw material will be greater than the hardness of the feed additive, so that the feed additive raw material can be ground and crushed, and the particle size will become smaller after grinding and crushing, and will be smaller than the size of the guide channel 211, that is, smaller than the spacing between two adjacent guide bars 21, so that the feed additive raw material with a small particle size will not be stuck in the guide channel 211, effectively avoiding the feed additive raw material stagnating in the guide channel 211 and rotating counterclockwise with the grinding body 20. Then, although the ground and crushed feed additive raw material will still contact the shell 10 under the action of centrifugal force, the friction between the feed additive raw material and the side wall of the grinding space 30 is rolling friction, and the friction force is small. Therefore, the ground and crushed feed additive raw material will still move downward in a clockwise spiral relative to the grinding body 20 under the guidance of the guide channel 211 under the action of its own gravity. In this way, on the one hand, the pressure between the feed additive raw material and the side wall of the grinding space 30 can be increased, thereby improving the grinding effect of the feed additive raw material; on the other hand, it can prevent the feed additive raw material from bouncing up and down due to being unable to move downward and then stagnating at a certain position in the guide channel 211, thereby ensuring the grinding efficiency.

[0046] Moreover, the angle between the extension direction of the guide channel 211 and the up-down direction of the technical solution of the present invention has a tendency to gradually increase, so that the guide channel 211 can gradually tend to be horizontal, that is, extend along the circumferential direction of the grinding body 20, so that the feed additive raw materials can be distributed in the guide channel 211 along the circumferential direction according to the gradually reduced particle size and irregular shape of the feed additive raw materials after grinding, thereby effectively reducing the risk of the feed additive raw materials clogging the guide channel 211 after grinding.

[0047] It should be noted that the situation of the feed additive raw materials bouncing up and down referred to here is specifically: if the guide channel 211 is set vertically, when there is no other feed additive raw material for squeezing above the feed additive raw material, or there are other relatively small feed additive raw materials for squeezing above the feed additive raw material, and the particle size of the feed additive raw material is smaller than the distance between the opposite side walls of the grinding space 30, the feed additive raw material cannot move downward only by its own weight to achieve grinding, and there is a probability that the feed additive raw material will bounce up and down and stagnate at a certain position in the guide channel 211.

[0048] Please refer to Figure 1 , Figure 2 as well as Figure 7 In some embodiments, the guide channel 211 includes a first channel 2111 and a second channel 2112, and one end of the first channel 2111 is connected to the feed port 12. One end of the second channel 2112 is connected to the other end of the first channel 2111, and the other end is connected to the discharge port 13. It can be understood that the feed additive raw material will first enter the second channel 2112 through the limit guide of the first channel 2111, and then be discharged through the discharge port 13 after passing through the limit guide of the second channel 2112.

[0049] Among them, the angle between the first channel 2111 and the up-down direction is smaller than the angle between the second channel 2112 and the up-down direction, that is, the first channel 2111 is more vertical than the second channel 2112, and the second channel 2112 is more horizontal than the first channel 2111.

[0050] In this way, the vertical form of the first channel 2111 can better convert the kinetic energy of the grinding body 20 into the energy of extruding the feed additive raw material, which is conducive to the extrusion and crushing of particles with larger particle sizes. When the second channel 2112 is horizontal, after the particles with larger particle sizes are crushed into a number of particles with smaller particle sizes and irregular shapes, the particles with smaller particle sizes can be dispersed in the horizontal second channel 2112 along the spiral direction of the second channel 2112, and the angle between the spiral direction of the second channel 2112 and the horizontal direction is small, so the second channel 2112 can extend spirally around the rotation center line of the grinding body 20, so that the second channel 2112 itself can have a longer length, so that the particles with smaller particle sizes can be dispersed in the second channel 2112, and the risk of the particles with smaller particle sizes blocking the second channel 2112 can be effectively reduced, thereby improving the grinding efficiency; wherein, the horizontal direction referred to in this embodiment is arranged perpendicular to the above-mentioned up and down directions.

[0051] Please refer to Figure 1 , Figure 2 as well as Figure 7In some embodiments, along the extension direction of the guide channel 211, the spacing between two adjacent guide bars 21 gradually decreases. It is understandable that the feed additive raw material will be continuously ground in the process of moving from the entrance of the guide channel 211 to the exit of the guide channel 211, so that the particle size of the particles will continue to decrease. Therefore, the spacing between two adjacent guide bars 21 of the present invention is set to gradually decrease to adapt to the situation that the particle size of the particles will continue to decrease, so that the guide channel 211 can maintain the limiting and guiding effect on the feed additive raw material, thereby ensuring the grinding effect of the feed additive raw material. It is understandable that the entrance of the guide channel 211 is the opening connected to the feed port 12, and the exit of the guide channel 211 is the opening connected to the discharge port 13.

[0052] Please refer to Figure 1 , Figure 2 , Figure 5 as well as Figure 7 In some embodiments, the protruding length of each guide bar 21 gradually decreases along the extension direction of the guide channel 211. It can be understood that the feed additive raw material will be continuously ground in the process of moving from the entrance of the guide channel 211 to the exit of the guide channel 211, so that the particle size of the particles will continue to decrease. Therefore, the protruding length of each guide bar 21 of the present invention is set to gradually decrease to adapt to the situation that the particle size of the particles will continue to decrease, so that the guide channel 211 can maintain the limiting and guiding effect on the feed additive raw material, thereby ensuring the grinding effect of the feed additive raw material.

[0053] Please refer to Figure 1 , Figure 2 , Figure 5 as well as Figure 7 In some embodiments, the grinding body 20 is set in a conical shape and is gradually expanded from top to bottom, that is, the grinding body 20 is narrow at the top and wide at the bottom, and correspondingly, the grinding space 30 is wide at the top and narrow at the bottom; for example, the grinding body 20 is set in a cone shape, and its outer diameter gradually increases from top to bottom. This arrangement is conducive to making the grinding space 30 adapt to the situation where the particle size of the particles is constantly decreasing, effectively reducing the probability that the distance between the two opposite side walls of the grinding space 30 is greater than the particle size of the particles and the particles cannot be ground, thereby ensuring the grinding effect of the feed additive raw materials.

[0054] Please refer to Figure 1 , Figure 2 , Figure 4 as well as Figure 5In some embodiments, the grinding body 20 includes at least two grinding bodies 20, and at least two grinding bodies 20 are arranged in the receiving cavity 11 at intervals. The number of the grinding bodies 20 can be two, three, or four, etc., and the present invention is not limited to this, and can be selected according to the actual product size and the required grinding efficiency.

[0055] The rotation directions of two adjacent grinding bodies 20 are consistent, and the guide bars 21 of the two adjacent grinding bodies 20 facing each other are arranged at an angle and cooperate to form a shearing structure, which is used to shear the feed additive raw materials.

[0056] In actual operation, when the rotation directions of two adjacent grinding bodies 20 are consistent, for example, they both rotate in the counterclockwise direction, there will be guide bars 21 facing each other in the two adjacent grinding bodies 20, and the guide bars 21 are arranged at an angle, for example, they can be arranged at a ninety-degree angle, so the guide bars 21 facing each other cooperate with the shearing structure, and the intersection of the guide bars 21 facing each other can shear the particles (the intersection can be referred to in Figure 4 and Figure 5 Therefore, when the feed additive raw material passes through the intersection of the guide bars 21 facing each other, the particles will be sheared by the shearing structure and changed from large particles to small particles, so that the grinding effect can be achieved, thereby further improving the grinding efficiency of the feed additive raw material grinding device.

[0057] It is understandable that there will be multiple groups of guide bars 21 facing each other in two adjacent grinding bodies 20, so there will be multiple intersections accordingly, and along the direction from top to bottom, the spacing between two adjacent intersections is set to gradually decrease. In actual operation, when a particle is located at one of the intersections, if its bottom can be supported by the guide bar 21 located below it, the shearing effect of the guide bar 21 on the particle can be guaranteed, and the particle size will gradually decrease during the grinding process. Therefore, the advantage of setting the spacing between the intersections to be gradually reduced in the present invention is that when the particle is located at any intersection, its bottom can always be well supported, thereby ensuring the grinding effect of the guide bar 21 on the particle.

[0058] Please refer to Figure 1 , Figure 4 as well as Figure 5, Further, the feed additive raw material grinding device further includes at least two first driving members 40. The first driving member 40 can be a component such as a motor that can generate a driving torque, and the present invention does not limit this. At least two first driving members 40 are both installed on the housing 10, and one first driving member 40 is in transmission connection with one grinding body 20 to respectively drive the grinding body 20 to rotate in the same rotation direction. In this way, the present invention can control at least two grinding bodies 20 to rotate in the same rotation direction through the arrangement of at least two first driving members 40 to achieve a shearing effect on the particles.

[0059] Of course, the present invention is not limited to this. In other embodiments, it can also be through the cooperation of a driving member and a transmission structure to simultaneously drive at least two grinding bodies 20 to rotate in the same rotation direction.

[0060] Please refer to Figure 1-Figure 3 , Figure 6-Figure 8 , In some embodiments, a first discharge channel 14 and a second discharge channel 15 that are connected and communicate are formed on the cavity side wall of the receiving cavity 11. The first discharge channel 14 extends along the circumferential direction of the housing 10, and the second discharge channel 15 extends in the vertical direction. Among them, there can be multiple first discharge channels 14, and the multiple first discharge channels 14 are arranged at intervals in the vertical direction.

[0061] When the grinding body 20 rotates, under the influence of centrifugal force, the feed additive raw material will enter the first discharge channel 14, and then enter the second discharge channel 15 from the first discharge channel 14, and finally discharge through the discharge port 13.

[0062] Among them, the feed additive raw material grinding device further includes a baffle 50. The baffle 50 covers the opening of the first discharge channel 14 and is provided with a material passing port 51 that communicates with the first discharge channel 14.

[0063] During the actual grinding process, when there is an over-grinding situation of the feed additive raw material, a large amount of dust will be generated, and some powders will adhere to the side wall of the grinding space 30, resulting in the need for later cleaning. Therefore, in order to prevent the occurrence of over-grinding, the present invention is provided with a first discharge channel 14 and a second discharge channel 15. The baffle 50 is used to filter the particles with larger particle sizes, and the particles that have reached the grinding size requirements can enter the first discharge channel 14 from the material passing port 51 and directly discharge through the discharge port 13 to effectively avoid the occurrence of over-grinding.

[0064] Please refer to Figure 3 , Figure 4 and Figure 6, Further, the grinding device for feed additive raw materials further includes a transmission belt 60 and a second driving member 70. The transmission belt 60 is disposed in the first discharge channel 14, and the transmission belt 60 includes a belt body 61 and a plurality of push plates 62. The plurality of push plates 62 are arranged at intervals along the extending direction of the belt body 61.

[0065] The second driving member 70 can be a component such as a motor that can generate a driving torque, and the present invention does not limit this. The second driving member 70 is installed on the housing 10 and is in transmission connection with the belt body 61. Among them, under the drive of the second driving member 70, the belt body 61 can rotate in the first discharge channel 14 so that the push plate 62 can push the feed additive raw materials from the first discharge channel 14 into the second discharge channel 15. In this way, the particles located in the first discharge channel 14 can be pushed to the second discharge channel 15 by the plurality of push plates 62, thereby effectively improving the discharging efficiency of the grinding device for feed additive raw materials.

[0066] Please refer to Figures 7 and 8 , In some embodiments, the first discharge channel 14 includes a discharge channel 141 and an installation channel 142. The discharge channel 141 is communicated with the installation channel 142 and the second discharge channel 15. The belt body 61 is embedded in the installation channel 142 and can rotate in the installation channel 142. The plurality of push plates 62 are located in the discharge channel 141 to push the feed additive raw materials located in the discharge channel 141 to the second discharge channel 15. In this way, the stable installation of the belt body 61 in the first discharge channel 14 can be ensured.

[0067] During the grinding process, due to different grinding degrees, there are feed additive raw materials of different sizes in the guiding channel 211. Among them, the feed additive raw materials that have been ground to a smaller size may be blocked by the feed additive raw materials of a larger size, resulting in over-grinding of the feed additive raw materials. In order to avoid over-grinding of the feed additive raw materials in the guiding channel 211, the feed additive raw materials with particle sizes meeting the requirements can enter the interior of the discharge channel 141 because their sizes are relatively small and smaller than the size of the discharge channel 141. Then, the rotation of the belt body 61 drives the rotation of the push plate 62, and the feed additive raw materials inside the discharge channel 141 are pushed until the feed additive raw materials move to the intersection of the discharge channel 141 and the second discharge channel 15 and enter the second discharge channel 15, and the feed additive raw materials with particle sizes meeting the requirements directly fall from the second discharge channel 15.

[0068] Please refer to Figure 3 , Figure 4 and Figure 8In some embodiments, the second driving member 70 includes a driving motor 71 and a connecting rod 72, the driving motor 71 is transmission-connected to the connecting rod 72, the connecting rod 72 is threadedly connected to the belt body 61, wherein the shell 10 may be provided with a through groove 16, the through groove 16 is connected to the first discharge channel 14, the connecting rod 72 is passed through the through groove 16, and can be threadedly connected to the belt body 61.

[0069] When the feed additive raw material needs to be transferred from the first discharge channel 14 to the second discharge channel 15, the driving motor 71 can drive the connecting rod 72 to rotate, thereby driving the belt body 61 to rotate in the first discharge channel 14. In this way, through the form of threaded connection, the belt body 61 can be rotated in the first discharge channel 14 while ensuring a simple and stable transmission structure.

[0070] Of course, in order to further improve the rotation efficiency and stability of the belt body 61, the present invention can also provide two second driving members 70, and the two second driving members 70 are respectively arranged on both sides of the belt body 61, thereby effectively improving the rotation efficiency and stability of the belt body 61.

[0071] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
