[0020] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0021] 1. The grain auxiliary grinding device for feed preparation is provided with three areas for fine grinding of grain raw materials, namely, a partition fine grinding area 1, a partition fine grinding area 2, and a material clamping grinding assembly. During the grinding process of the grain raw materials, the grain raw materials can be divided, dispersed, and separately ground, thereby effectively avoiding the heavy grinding burden caused by only one grinding area in the prior art. Therefore, it can not only solve the problem of thorough grinding, but also improve the grinding efficiency, thereby reducing the grinding burden;

[0022] 2. The height L of the wide channel area of ​​the grain auxiliary grinding device for feed preparation can obtain a wider wide channel area, so that the larger grain raw materials passing through the filter can be clamped by the first magnetic plate and the second magnetic plate in the wide channel area, so that the effect of facilitating the grinding of the grain raw materials can be further improved. The small height of the drop zone can make the grain raw materials passing through the filter enter the wide channel area faster, thereby reducing the distance between the drop zone and the wide channel area; the small height of the discharge zone allows the finely ground grain feed to be guided by the discharge zone and quickly slide along the inner wall of the discharge barrel to the bottom of the discharge barrel, so that the grain feed that falls into the discharge barrel through the discharge zone can form a V-shaped accumulation in the discharge barrel, which forms a concave area in the middle of the discharge barrel. At this time, the grain feed that falls into the discharge barrel through the drop channel just fills the concave area, so that the ground grain feed can be evenly filled in the discharge barrel, avoiding uneven accumulation of feed in the discharge barrel and causing unstable center of gravity of the grinding barrel;

[0023] 3. The width setting of the drop zone can make the grain raw materials passing through the filter quickly enter the wide channel zone, thereby avoiding accumulation and jamming; the width of the wide channel zone can make the distance between the first magnetic plate and the second magnetic plate larger in the default state, so that when the first magnetic plate and the second magnetic plate are close to each other, on the one hand, more grain raw materials can be clamped, thereby improving the efficiency of fine grinding of grain raw materials, and in addition, the second magnetic plate can obtain a greater clamping force when approaching the first magnetic plate, thereby further clamping and breaking the grain raw materials passing through the first magnetic plate and the second magnetic plate; the partition fine grinding zone 2 with a small width can improve the effect of fine grinding of grain raw materials; the discharging zone with a width greater than that of the partition fine grinding zone 2 can make the grain feed milled in the partition fine grinding zone 2 fall quickly into the discharging barrel, avoiding accumulation or jamming in the discharging zone;

[0024] 4. The grain auxiliary grinding device for feed preparation can effectively stir the grain raw materials to be ground in the grinding cylinder to avoid jamming, and can handle foreign matter in the grain raw materials to be ground, through the first rod and the second rod that can rotate and move up and down;

[0025] 5. The grain auxiliary grinding device for feed preparation, the long sliding rod arranged in the device can not only drive the second rod to move up and down to block the foreign matter in the grain raw materials to be ground, but also pump gas into the first air outlet pipe and the second air outlet pipe when the long sliding rod moves up and down, so as to clear the grains blocked on the fine grinding net and drive the fine grain raw materials in the partition fine grinding area two to accelerate through the partition fine grinding area two and fall into the discharge barrel.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0041] Example 1: Reference Figure 1-Figure 11 A grain auxiliary grinding device for feed preparation includes a grinding cylinder 1, and also includes: a main shaft 11 rotatably arranged in the grinding cylinder 1, a first grinding wheel 14 and a second grinding wheel 15 are fixedly connected to the main shaft 11, and a coarse grinding area 141 is formed between the first grinding wheel 14 and the inner wall of the grinding cylinder 1; a filter screen 142 fixedly connected to the grinding cylinder 1, a fine grinding screen 143 is fixedly connected to the filter screen 142, the fine grinding screen 143 extends between the first grinding wheel 14 and the second grinding wheel 15, and the fine grinding screen 143 forms a partitioned fine grinding area 144 between the first grinding wheel 14 and the second grinding wheel 15, and a material dropping channel 145 is opened on the second grinding wheel 15, and the material dropping channel 141 is fixedly connected to the first grinding wheel 14 and the second grinding wheel 15. 45 passes through the end of the second grinding wheel 15, and is used for fine grinding of the raw material after rough grinding; a clamping and grinding assembly is arranged between the second grinding wheel 15 and the inner wall of the grinding cylinder 1, and is used for clamping and grinding the raw material when the raw material passes through the clamping and grinding assembly; a partitioned fine grinding area 156 is formed between the lower wall 1502 of the second grinding wheel 15 and the grinding cylinder 1, and is used for fine grinding of the raw material passing through the partitioned fine grinding area 156; a discharge cylinder 10 is located at the lower end of the grinding cylinder 1; an upper bracket 13 and a lower bracket 112 are fixedly connected to the grinding cylinder 1, respectively, and a main shaft 11 is rotatably connected to the upper bracket 13 and the lower bracket 112; a motor 12 is installed on the grinding cylinder 1, and the motor 12 is connected to the main shaft 11;

[0042] When the device is in use, the grain raw materials are poured into the grinding cylinder 1 from the top, and the first grinding wheel 14 and the second grinding wheel 15 are driven by the motor 12 to rotate in the grinding cylinder 1. When the grain raw materials pass through the rough grinding area 141, the first grinding wheel 14 rotates, so that the grain raw materials are ground in the rough grinding area 141.

[0043] The crushed grain raw materials are screened by the filter 142, so that a part of the grain raw materials pass through the filter 142 and enter between the second grinding wheel 15 and the grinding cylinder 1, while the grain raw materials that do not pass through the filter 142 will move to the inclined fine grinding mesh 143 and come to the partition fine grinding area 144, and the grain raw materials on the fine grinding mesh 143 located in the partition fine grinding area 144 are finely ground by the rotating first grinding wheel 14 and the second grinding wheel 15, and the ground fine grain raw materials are directly discharged into the discharge cylinder 10 through the discharge channel 145;

[0044] The grain raw materials passing through the filter screen 142 will enter between the second grinding wheel 15 and the grinding cylinder 1, and a material clamping and rubbing assembly is arranged between the second grinding wheel 15 and the grinding cylinder 1. Therefore, the grain raw materials passing through the filter screen 142 will be clamped when passing through the material clamping and rubbing assembly, so that the grain raw materials are further broken and crushed, and the material clamping and rubbing assembly will subsequently rub the clamped grain raw materials, thereby achieving a good grinding effect of the grain raw materials. After being ground by the material clamping and rubbing assembly, the grain raw materials directly pass through the second partition fine grinding area 156 and then enter the discharge cylinder 10;

[0045] The grain raw materials not clamped by the material clamping and grinding components will be finely ground when passing through the second partition fine grinding area 156, and then ground into grain feed raw materials that meet the requirements;

[0046] It should be understood that grinding teeth are provided on the inner wall of the grinding cylinder 1 in the rough grinding area 141, the outer wall of the first grinding wheel 14, the lower wall 1502 of the second grinding wheel 15 at the partition fine grinding area 156, the inner wall of the grinding cylinder 1 and the bottom surface of the first grinding wheel 14 to further facilitate the grinding of the grain raw materials;

[0047] Therefore, the present device is provided with three areas for fine grinding of grain raw materials, namely, partitioned fine grinding area 144, partitioned fine grinding area 2 156, and clamping grinding assembly. During the grinding process of grain raw materials, the grain raw materials can be zoned, dispersed, and separately ground, thereby effectively avoiding the heavy grinding burden caused by only one grinding area in the prior art. Therefore, it can not only solve the problem of thorough grinding, but also improve the grinding efficiency, thereby reducing the grinding burden.

[0048] Reference Figure 2 , Figure 4 , Fig. 9 , Fig.10 A wide channel area 151 is formed between the second grinding wheel 15 and the grinding cylinder 1. The material clamping and grinding assembly is located in the wide channel area 151. The material clamping and grinding assembly includes a plurality of first magnetic plates 152 circumferentially installed on the upper wall 1501 of the second grinding wheel 15 at equal intervals. A guide rod 153 is slidably connected to the grinding cylinder 1. One end of the guide rod 153 is fixedly connected to a second magnetic plate 155. A plurality of guide rods 153 and second magnetic plates 155 are arranged circumferentially. The guide rod 153 is connected to the grinding cylinder 1 through a spring 154. The first magnetic plates 152 and the second magnetic plates 155 are attracted to each other.

[0049] The clamping and grinding assembly is realized by the first magnetic plate 152 on the outer wall of the second grinding wheel 15 reciprocatingly approaching the second magnetic plate 155 on the inner wall of the grinding cylinder 1 when the second grinding wheel 15 rotates. Since the first magnetic plate 152 and the second magnetic plate 155 can be attracted to each other, when the first magnetic plate 152 approaches the second magnetic plate 155, the second magnetic plate 155 is attracted and closely adheres to the first magnetic plate 152, and in the process of closely adhering, the grain raw materials passing through the wide channel area 151 are clamped, so as to achieve the effect of breaking and crushing the clamped grain raw materials;

[0050] The second grinding wheel 15 is rotating, so after the first magnetic plate 152 and the second magnetic plate 155 are attracted to each other, the first magnetic plate 152 and the second magnetic plate 155 can rub the clamped grain raw materials, thereby effectively grinding the clamped grain raw materials;

[0051] Therefore, the material clamping and grinding assembly provided in the wide channel area 151 of the device can realize the crushing and fine grinding of the grain raw materials that pass through the filter screen 142 after being ground by the first grinding wheel 14, and realize the fine grinding of the grain raw materials in advance, thereby reducing the grinding burden of the second partition fine grinding area 156, and effectively improving the grinding effect and grinding efficiency;

[0052] When the first magnetic plate 152 and the second magnetic plate 155 are separated, the second magnetic plate 155 will be reset under the thrust of the spring 154;

[0053] The grinding cylinder 1 is provided with legs 101 to facilitate installation of the grinding cylinder 1 .

[0054] Example 2: Reference Figure 2 , a grain auxiliary grinding device for feed preparation, which is basically the same as Example 1, and further: a material drop zone 150 and a material discharge zone 1500 are formed between the second grinding wheel 15 and the grinding cylinder 1, the height of the second grinding wheel 15 is L, the height of the material drop zone 150 is L1, the height of the wide channel zone 151 is L2, the height of the partitioned fine grinding zone 2 156 is L3, and the height of the material discharge zone 1500 is L4, then the following constraint relationship exists:

[0055] L=L1+L2+L3,

[0056] L2=1.8L3=4L1,

[0057] L4 = 1 / 10L;

[0058] Reference Figure 2 , Figure 4The height L2 of the wide channel area 151 can obtain a wider wide channel area 151, so that the larger grain raw materials passing through the filter screen 142 can be clamped by the first magnetic plate 152 and the second magnetic plate 155 in the wide channel area 151, so that the effect of grinding the grain raw materials can be further improved.

[0059] The material drop area 150 with a small height can make the grain raw materials passing through the filter screen 142 enter the wide channel area 151 more quickly, thereby reducing the distance between the material drop area 150 and the wide channel area 151;

[0060] The discharge area 1500 with a relatively small height allows the finely ground grain feed to slide quickly along the inner wall of the discharge barrel 10 to the bottom of the discharge barrel 10 through the guidance of the discharge area 1500, so that the grain feed that passes through the discharge area 1500 and falls into the discharge barrel 10 and accumulates can form a V-shaped accumulation in the discharge barrel 10, which forms a concave area in the middle of the discharge barrel 10. At this time, the grain feed that falls into the discharge barrel 10 through the drop channel 145 just fills the concave area, so that the ground grain feed can be evenly filled in the discharge barrel 10, avoiding uneven accumulation of feed in the discharge barrel 10 and causing the center of gravity of the grinding barrel 1 to be unstable;

[0061] The width of the blanking area 150 is W1, the width of the wide channel area 151 is W2, the width of the partitioned fine grinding area 156 is W3, and the width of the discharge area 1500 is W4, then the following constraint relationship exists:

[0062] W2=W1=4W3=3W4;

[0063] The width setting of the material drop area 150 can enable the grain raw materials passing through the filter screen 142 to quickly enter the wide channel area 151, thereby avoiding accumulation and jamming;

[0064] The width of the wide channel area 151 can make the distance between the first magnetic plate 152 and the second magnetic plate 155 larger in the default state, so that when the first magnetic plate 152 and the second magnetic plate 155 are close to each other, on the one hand, more grain raw materials can be clamped, thereby improving the efficiency of fine grinding of grain raw materials, and in addition, when the second magnetic plate 155 is close to the first magnetic plate 152, a greater clamping force can be obtained, thereby further crushing the grain raw materials passing through the first magnetic plate 152 and the second magnetic plate 155;

[0065] The second partition fine grinding area 156 with a small width can improve the effect of fine grinding of the grain raw materials;

[0066] The discharge area 1500 , which is wider than the partitioned fine grinding area 156 , can allow the grain feed ground in the partitioned fine grinding area 156 to quickly fall into the discharge barrel 10 , avoiding accumulation or jamming in the discharge area 1500 .

[0067] Example 3: Reference Figure 1 , Figure 6 , Fig. 9 , Fig.10 , Fig.11 , a grain auxiliary grinding device for feed preparation, which is basically the same as that of Example 2, and further, a first rod 131 is fixedly connected to the upper bracket 13, a cross bar 161 is provided on the first grinding wheel 14, a second rod 162 is fixedly connected to the cross bar 161, and the second rod 162 is staggered with the first rod 131, so that when the first grinding wheel 14 rotates, the second rod 162 cooperates with the first rod 131 to stir the raw materials in the upper end of the grinding cylinder 1;

[0068] A plurality of long slide bars 16 are circumferentially slidably connected between the first grinding wheel 14 and the second grinding wheel 15. The ends of the long slide bars 16 are connected to the bottom of the second grinding wheel 15 via tension springs 163. A cross bar 161 is connected to the long slide bars 16 to drive the second rods 162 to move up and down between the first rods 131 when the long slide bars 16 reciprocate up and down.

[0069] An arc-shaped curved plate 132 is fixedly connected to the upper bracket 13, and one end of the long sliding rod 16 corresponds to the arc-shaped curved plate 132;

[0070] When in use, when the first grinding wheel 14 and the second grinding wheel 15 rotate, the cross bar 161 and the second rod 162 will be driven to rotate together. At this time, the cross bar 161 and the second rod 162 can stir the grain raw materials to be ground in the grinding cylinder 1 when rotating, which can effectively prevent the grain raw materials to be ground from getting stuck in the grinding cylinder 1.

[0071] In addition, when the first grinding wheel 14 and the second grinding wheel 15 rotate, the long slide bar 16 will move downward when passing through the arc-shaped curved plate 132, and the second rod 162 will move downward together with it when moving downward. When the long slide bar 16 is not in contact with the arc-shaped curved plate 132, the long slide bar 16 will move upward under the pull of the tension spring 163, thereby forming a trajectory in which the second rod 162 repeatedly moves up and down between the first rod 131. Therefore, when the second rod 162 moves up and down, foreign objects in the grain raw materials to be ground in the grinding cylinder 1 can be effectively stuck on the second rod 162, and blocked at the first rod 131 and the second rod 162, so as to prevent foreign objects from entering the coarse grinding area 141.

[0072] Therefore, the first rod 131 and the second rod 162 that can rotate and move up and down provided in the device can effectively stir the grain raw materials to be ground in the grinding cylinder 1 to avoid jamming, and can handle foreign matter in the grain raw materials to be ground.

[0073] Embodiment 4:

[0074] Reference Figure 4 , Figure 8 , Fig.10 , Fig.11 , a grain auxiliary grinding device for feed preparation, which is basically the same as Example 3, and further includes: a first air inlet pipe 1661 and a first air outlet pipe 1662, and the first air outlet pipe 1662 faces the fine grinding mesh 143;

[0075] The second air inlet pipe 1671 and the second air outlet pipe 1672 are provided, and the second air outlet pipe 1672 faces the second fine grinding area 156. The second air outlet pipe 1672 is provided with a third air outlet pipe 1673, and the third air outlet pipe 1673 faces the second magnetic plate 155.

[0076] The second grinding wheel 15 is provided with a plurality of cavities 164 corresponding to the long slide bar 16. The long slide bar 16 is located in the cavity 164 and is fixedly connected with a piston plate 165. The piston plate 165 is slidably connected in the cavity 164. The cavity 164 is divided into a first chamber 166 and a second chamber 167 by the piston plate 165. The first air inlet pipe 1661 and the first air outlet pipe 1662 are connected to the first chamber 166. The first air inlet pipe 1661 and the first air outlet pipe 1662 are both provided with a one-way valve. The second air inlet pipe 1671 and the second air outlet pipe 1672 are connected to the second chamber 167. The second air inlet pipe 1671 and the second air outlet pipe 1672 are both provided with a one-way valve. The main shaft 11 is provided with an air passage 111, which runs through to the end of the main shaft 11. The first air inlet pipe 1661 and the second air inlet pipe 1671 are both connected to the air passage 111.

[0077] When in use, the long slide bar 16 is driven by the arc-shaped curved plate 132 to slide up and down in the first grinding wheel 14 and the second grinding wheel 15, which causes the piston plate 165 to slide in the cavity 164. Therefore, during the sliding process of the piston plate 165, the gas in the first chamber 166 and the second chamber 167 are squeezed respectively, and the squeezed gas is sprayed onto the fine grinding net 143 through the first gas outlet pipe 1662, so as to clear the grains blocked on the fine grinding net 143, thereby improving the effect of the fine grinding net 143 on grinding the grain raw materials;

[0078] The gas ejected from the second gas outlet pipe 1672 will be ejected into the second partition fine grinding area 156, and the gas ejected into the second partition fine grinding area 156 can make the fine grain raw materials in the second partition fine grinding area 156 pass through the second partition fine grinding area 156 as quickly as possible and fall into the discharge cylinder 10, thereby improving the grinding efficiency. In addition, the ejected gas can also clean the inner wall of the grinding cylinder 1 at the second partition fine grinding area 156, further improving the grinding efficiency.

[0079] In addition, the third air outlet pipe 1673 can spray air toward the second magnetic plate 155 to remove the grains adhering to the second magnetic plate 155, thereby effectively improving the grinding effect of the grains;

[0080] The first air intake pipe 1661 and the second air intake pipe 1671 inhale air into the first chamber 166 and the second chamber 167 respectively through the air passage 111;
