Description

Technical Field

[0001] The present application relates to the technical field of grain crushing and grinding, and in particular to a multifunctional grain crushing and grinding machine. Background Art

[0002] Grain grinding is an important processing step, which involves the physical processing of grain raw materials into fine powder for subsequent use or further processing. The effect of grain grinding will be affected by many factors, including grinding method, equipment type, operating conditions, etc.

[0003] For example, a grain full crushing and grinding device with publication number CN115254301A relates to the field of grain grinding technology, and includes a grinding box and a collecting box. The collecting box is fixedly installed on the bottom of the grinding box, and an observation window is embedded and installed on the outside of the grinding box. In this prior art, a grinding and dispersing component is provided to drive the grinding mechanism to rotate. The grinding and dispersing component rotates, and the grains can be well and stably ground. Some fine particles after grinding can enter the grinding roller through the through hole. When the grinding and dispersing component continues to rotate, the outer sleeve can rotate on the inner shaft due to the centrifugal force of the rotation, and the connecting shaft makes a circular motion in the grinding roller, which can well disperse the grain particles entering the grinding roller after grinding. At the same time, the disperser can also rotate to assist the dispersion of the grains, which not only ensures the grinding effect of the grains but also ensures the dispersion effect of the grains after grinding, so that the ground grain particles are distinct and not easy to agglomerate.

[0004] However, the above-mentioned prior art still has some defects when grinding grains: 1. After the ground fine particles in the above-mentioned patent application enter the grinding roller through the through hole, during the subsequent rotation of the grinding roller, the fine particles may still return to the grinding box through the through hole, thereby weakening the effect of the grinding and dispersing component, and relying solely on the disperser without drying treatment cannot achieve an effective dispersion effect on the grain particles containing moisture, which will cause the ground grain particles to still clump due to the presence of moisture, thereby reducing the quality of the finished grain particles.

[0005] In the above patent application, during the dust removal process, some grain crushers may be ground to a very small particle size, and some grain crushers may also be adsorbed when the dust suction sleeve is vacuuming, thereby resulting in a reduction in the content of grain crushers in the finished product. In addition, when the scraper scrapes the dust on the dust suction sleeve, the dust may still float back into the grinding box during the falling process, resulting in a decrease in the cleanliness of the grain crushers in the finished product.

[0006] The above patent application can only produce grains of a specific particle size. When the particle size required for the production of the same grain is different, the prior art cannot complete the corresponding task. At this time, it is necessary to replace it with another device, thereby increasing the cost of the device.

[0007] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for grain grinding. Summary of the invention

DETAILED DESCRIPTION

[0045] The following is combined with Figures 1 to 10 This application is described in further detail.

[0046] The embodiment of the present application discloses a multifunctional grain crushing and grinding machine, which can ensure that the grains can be fully crushed and ground and can ensure that the grains are dried, dusted and graded, thereby improving the quality of the finished grain crumbs.

[0047] Embodiment 1:

[0048] Reference Figure 1 and Figure 2 A multifunctional grain crushing and grinding machine includes a cylinder shell 1, a rotating rod 11 is installed in the cylinder shell 1, and a feeding component 2, a crushing component 3 and a grinding component 4 are installed in sequence along the axial direction of the rotating rod 11.

[0049] The crushing assembly 3 includes a crushing blade 31 and a screen 32. The screen 32 is used to screen the grain particles that meet the size into the grinding assembly 4 at the bottom of the cylinder shell 1 for grinding. The crushing blade 31 is installed on the rotating rod 11, and the screen 32 is installed at the lower end of the crushing blade 31 along the axial direction of the rotating rod 11.

[0050] Reference Figure 1 , Figure 5 and Fig. 9 The grinding assembly 4 includes a first grinding disc 41, which is mounted at the bottom of the rotating rod 11. A second grinding disc 42 is mounted at the lower end of the first grinding disc 41 along the axis of the rotating rod 11. A grinding wall 43 is mounted on the inner wall of the cylinder shell 1 corresponding to the outer circles of the first grinding disc 41 and the second grinding disc 42. The first grinding disc 41 and the second grinding disc 42 grind the grain particles. The grinding wall 43 cooperates with the first grinding disc 41 and the second grinding disc 42 to grind the grain particles that do not meet the size requirements again. The first grinding disc 41 and the second grinding disc 42 are provided with a size adjustment assembly 44 for adjusting the grinding distance.

[0051] Among them, the feeding component 2 can disperse the grains so that the grains can be evenly scattered in the cylinder shell 1, avoiding excessive pressure on the single-side crushing blade 31 to damage it or making the grain crushing process uneven and insufficient. In the specific implementation process, before the machine is operated, the size adjustment component 44 is adjusted according to the grain particle size requirements so that the distance between the first grinding disc 41 and the second grinding disc 42 and the distance between the first grinding disc 41, the second grinding disc 42 and the grinding wall 43 meet the required grain particle size standard, and the grains are fed into the cylinder shell 1 through the feeding component 2. The grains can be evenly dispersed in the cylinder shell 1 after the dispersion treatment of the feeding component 2. During the falling process of the grains, the rotating crushing blade 31 crushes the grains, and the grain fragments that meet the requirements will be sieved from the constantly vibrating screen 32 and fall into the grinding component 4 at the bottom of the cylinder shell 1 for grinding, and the grain fragments that do not meet the size will continue to be crushed by the crushing blade 31 until the grain fragments can pass through the screen 32 and fall into the grinding component 4.

[0052] Among them, the grinding component 4 includes a drying facility, and the first grinding disc 41 and the second grinding disc 42 rotate in opposite directions. During specific operation, the grain fragments fall between the first grinding disc 41 and the second grinding disc 42. Under the action of centrifugal force, the grain fragments move toward the inner wall of the cylinder shell 1. During the movement, the grain fragments are ground between the first grinding disc 41 and the second grinding disc 42. Since the first grinding disc 41 and the second grinding disc 42 rotate in opposite directions, the grain fragments can be ground more fully and evenly with the cooperation of the two. Under continuous grinding, the particle size of the grain particles will continue to decrease until it becomes the required particle size. When the grain fragments reach the edge of the first grinding disc 41 and the second grinding disc 42, the hot air force blown out by the drying facility is adjusted to blow up the grain fragments that meet the requirements, and these grain fragments are sent out of the cylinder shell 1 and then collected by a collecting device.

[0053] Grain crumbs that do not meet the requirements will be ground again between the first grinding disc 41, the second grinding disc 42 and the grinding wall 43 until they can be blown up by hot air. At the same time, the hot air can dry the grain crumbs and remove any moisture that may be present, so that the collected grain crumbs will not clump together, thereby improving the quality of the grain crumbs.

[0054] Reference Figure 2 In order to enable the grain to be quantitatively transported and evenly dispersed in the device, the feeding assembly 2 includes a feeding hopper 21 and a dispersion box 22. A feeding pipe 23 is installed at the bottom of the feeding hopper 21, which penetrates the cylinder shell 1 and extends radially along the cylinder shell 1. A screw conveyor 24 is provided in the feeding pipe 23. The dispersion box 22 is installed on the rotating rod 11, and the dispersion box 22 is connected with the feeding pipe 23.

[0055] The top of the dispersion box 22 is in the shape of a truncated cone, and the rotating rod 11 is equipped with a plurality of dispersion blades 25 in the inner part of the dispersion box 22 to disperse the grains delivered by the feed pipe 23 so that the grains can be evenly distributed. A guide ring 26 is installed at the bottom of the dispersion box 22 along the axis direction of the rotating rod 11.

[0056] Among them, the closer the top cone of the dispersion box 22 is to the top of the cylinder shell 1, the smaller the diameter is, which can prevent the grains that are knocked away by the dispersion blades 25 from flying out from the top of the dispersion box 22 when the dispersion blades 25 disperse the grains, and thus the grains may not be effectively guided. The farther the guide ring platform 26 is from the dispersion box 22 along the axis direction of the rotating rod 11, the larger the diameter is. The guide ring platform 26 can guide the falling direction of the grains, thereby facilitating the crushing of the grains by the crushing blade 31. In the specific implementation process, the grains are poured into the feed hopper 21, and the grains enter the dispersion box 22 in a quantitative manner through the screw conveyor 24, which can prevent the grains from clogging the device and causing damage to the device. The dispersion blades 25 rotate with the rotating rod 11 to disperse and disrupt the grains, so that the grains can be evenly distributed inside the cylinder shell 1, avoiding damage to the single crushing blade 31. The grains dispersed and disrupted by the dispersion blades 25 can be guided by the guide ring platform 26 to keep the grains away from the rotating rod 11 after falling, thereby making the grains closer to the blade of the crushing blade 31, thereby improving the crushing efficiency of the grains.

[0057] Reference Figure 2 and Figure 3 Since the grains may be mixed with dust, which may affect the quality of the finished grain particles, in order to remove the dust in the grains, a dust removal assembly 5 is installed between the feeding assembly 2 and the crushing assembly 3 along the axial direction of the rotating rod 11.

[0058] The dust removal assembly 5 includes a dust suction hole 51, a filter screen 52, a rotating rod 53 and a spiral blade 54. The dust suction hole 51 is opened on the cylinder shell 1, and the filter screen 52 is installed on the dust suction hole 51. The top of the rotating rod 53 is rotatably installed with the cylinder shell 1 through a bearing, and the bottom of the rotating rod 53 is installed with a spiral blade 54.

[0059] A dust suction ring 55 is disposed on the outer wall of the cylinder shell 1 corresponding to the dust suction hole 51 .

[0060] Among them, the dust suction ring cylinder 55 is connected to the cylinder shell 1 by a snap-fit ​​connection, and the snap-fit ​​connection is sealed. During the specific implementation process, under the drive of an external air pump, the dust suction ring cylinder 55 is evacuated to form a negative pressure in the dust suction ring cylinder 55. At this time, the dust in the grains guided by the guide ring platform 26 is sucked into the dust suction ring cylinder 55 because of its light weight, and due to the presence of the filter net 52 on the dust suction hole 51, the grains will not fall into the dust suction ring cylinder 55, thereby ensuring that the dust in the grains can be removed without affecting the amount of grains.

[0061] When the grains enter the dispersion box 22, the rotating rod 53 is energized, and the rotating rod 53 transmits the current to the spiral blades 54, so that the spiral blades 54 can electrostatically remove the dust. At the same time, the spiral blades 54 begin to rotate under the action of the negative pressure airflow of the dust suction ring 55, which not only increases the contact area between the spiral blades 54 and the dust, thereby achieving the purpose of comprehensive dust removal, but also can further disperse the grains and improve the grain crushing efficiency.

[0062] After the grain crushing and grinding process is completed, the dust collection ring 55 and the filter screen 52 can be removed for cleaning. In addition, the top of the cylinder shell 1 can also be removed to clean the dust on the spiral blades 54, thereby ensuring that the dust removal efficiency of the dust removal component 5 will not be reduced when it works next time.

[0063] Reference Figure 4 In order to fully crush the grains, each crushing blade 31 has a different length and is located at a different height of the rotating rod 11, so as to crush the grains at different positions.

[0064] The screen 32 is evenly provided with a plurality of first arc-shaped protrusions 33 along the circumference of the outer ring thereof, and the inner wall of the cylinder shell 1 is provided with second arc-shaped protrusions 34 matched with the first arc-shaped protrusions 33 .

[0065] During the specific implementation process, the grains are dedusted by the dust removal component 5 and fall into the crushing component 3. The crushing blades 31 of different lengths and heights begin to crush the grains, ensuring that the grains at various positions inside the cylinder shell 1 can be crushed, thereby ensuring the success rate of grain crushing.

[0066] The screen 32 rotates synchronously with the rotation of the rotating rod 11, and the first arc-shaped protrusion 33 on the outer circle of the screen 32 cooperates with the second arc-shaped protrusion 34 on the inner wall of the cylinder shell 1 to make the screen 32 vibrate. The grain particles on the screen 32 can be screened more effectively and fully under the vibration, and the grain particles that meet the requirements fall into the grinding component 4 for grinding.

[0067] Reference Figure 2 and Figure 6 A first cavity 6 is provided between the screen 32 and the first grinding disc 41. A guide frustum 411 is provided on the top of the first grinding disc 41. The diameter of the guide frustum 411 gradually decreases from the top to the bottom of the first grinding disc 41. The bottom of the first cavity 6 is connected to the top of the guide frustum 411.

[0068] A feeding hole 412 is provided in the center of the first grinding disc 41 , and grain fragments are introduced between the first grinding disc 41 and the second grinding disc 42 for grinding. The first grinding disc 41 and the rotating rod 11 are connected by a plurality of rods.

[0069] Among them, the bottom of the guiding circular table 411 is connected to the top of the feed hole 412, so that the grain fragments falling on the guiding circular table 411 are directly guided into the feed hole 412 under the action of gravity. In the specific implementation process, the grain fragments that meet the size requirements and are screened by the screen 32 fall on the guiding circular table 411 through the first cavity 6, and the guiding circular table 411 guides the grain fragments into the feed hole 412, and then the grain fragments fall onto the second grinding disc 42 through the feed hole 412, and under the action of centrifugal force, the grain fragments slide to between the first grinding disc 41 and the second grinding disc 42 for grinding.

[0070] Reference Fig. 9 In order to make the particle size of the ground grain particles output as needed, the size adjustment component 44 includes a threaded box 441, which is installed on the outer circle of the first grinding disc 41 and has multiple threads evenly installed along its circumference. The threaded box 441 is connected to a first threaded rod 442 by threaded rotation, and the end of the first threaded rod 442 away from the threaded box 441 is connected to a grinding block 443.

[0071] During the specific implementation process, before the device is started, the distance between the grinding block 443 and the grinding wall 43 can be adjusted by adjusting the first threaded rod 442 so that the first threaded rod 442 enters or comes out of the threaded box 441. Then, when the grain fragments are ground between the first grinding disc 41 and the grinding wall 43, grain fragments of a specific particle size can be ground at a specific distance, so that the corresponding grain fragments can be obtained according to the particle size requirements of the grain, thereby reducing the cost of the device.

[0072] Reference Figure 8 and Fig. 9 In order to grind the grains more effectively between the first grinding disc 41 and the second grinding disc 42, a planetary gear 421 is installed between the second grinding disc 42 and the rotating rod 11. The sun gear of the planetary gear 421 is installed on the rotating rod 11. A plurality of linkage rods 422 are installed along the height direction of the bottom of the cylinder shell 1. The end of the linkage rod 422 away from the cylinder shell 1 rotates the planetary wheel with the planetary gear 421 installed through a bearing. The toothed disc of the planetary gear 421 is installed in the center of the second grinding disc 42.

[0073] A plurality of threaded boxes 441 are evenly installed along the circumference of the outer ring of the second grinding disc 42 . A first threaded rod 442 is connected to the threaded box 441 through threaded rotation. A grinding block 443 is also connected to one end of the first threaded rod 442 away from the threaded box 441 .

[0074] An arc-shaped guide plate 423 is provided at the front end of the grinding block 443 of the second grinding disc 42 along the rotation direction thereof, so as to guide the broken grains to be ground between the grinding wall 43 and the grinding block 443 .

[0075] During the specific implementation process, the rotating rod 11 rotates to drive the sun gear of the planetary gear 421 to rotate, and the sun gear then drives the planetary gear to rotate. Since the planetary gear is rotatably mounted on the linkage rod 422 through the bearing, and the linkage rod 422 is mounted on the cylinder shell 1, the planetary gear begins to rotate in the opposite direction of the sun gear rotation direction, and drives the toothed disc of the planetary gear 421 to rotate in the same direction. Since the toothed disc is installed in the center of the second grinding disc 42, the second grinding disc 42 also rotates in the opposite direction of the sun gear rotation direction, and then the first grinding disc 41 and the second grinding disc 42 rotate in opposite directions, which can have a good and effective grinding effect on the grain particles between the two, so that the grain particles can reach the required particle size requirements, thereby improving the efficiency of grain grinding.

[0076] In addition, the second grinding disc 42, like the first grinding disc 41, can adjust the distance between the grinding block 443 and the grinding wall 43 by adjusting the first threaded rod 442, so that corresponding grain fragments can be obtained according to the grain particle size requirements, reducing the cost of the device.

[0077] At the same time, since the grinding block 443 of the second grinding wheel 42 is provided with an arc guide plate 423 at the front end along the rotation direction, the grains that have been ground by the first grinding wheel 41 and the second grinding wheel 42 and do not meet the requirements can be guided by the arc guide plate 423 to the grinding wall 43 and the grinding block 443 for grinding again, so that the grain particles are ground to the required particle size that meets the requirements.

[0078] Reference Fig. 9 and Fig.10 , the grinding wall 43 is provided with dot-shaped protrusions.

[0079] The grinding blocks 443 of the first grinding disc 41 and the second grinding disc 42 are also provided with dot-shaped protrusions on one side close to the grinding wall 43 .

[0080] Among them, the dot-shaped protrusions can increase the friction between the grinding wall 43 and the grinding block 443 during grinding, so that the grain particles can be ground more fully. In the specific implementation process, the grain particles that have been ground by the first grinding disc 41 and the second grinding disc 42 and do not meet the required particle size standard will be moved to between the grinding block 443 and the grinding wall 43 under the action of immediate change for grinding again. The dot-shaped protrusions on the grinding wall 43 and the dot-shaped protrusions on the grinding block 443 cooperate with each other to grind the grain particles more fully and thus make them reach the required particle size standard.

[0081] Embodiment 2:

[0082] Reference Figure 6 and Figure 7In order to control the particle size of the grain particles by adjusting the distance between the first grinding disc 41 and the second grinding disc 42, the size adjustment component 44 also includes a grinding ring 444, which cooperates with the second grinding disc 42 to grind the grain particles. The grinding ring 444 is installed in the first grinding disc 41, and the grinding ring 444 is slidably connected to the inner wall of the first grinding disc 41.

[0083] A plurality of second threaded rods 445 are installed along the circumference of the guide table surface 411 to adjust the distance between the grinding ring 444 and the second grinding disc 42. The second threaded rods 445 and the first grinding disc 41 are rotatably installed via bearings, and the second threaded rods 445 and the grinding ring 444 are rotatably connected via threads.

[0084] Among them, the second threaded rod 445 is installed on the first grinding disc 41 perpendicular to the guide circular table surface 411 to prevent grain fragments from being stuck at the intersection of the second threaded rod 445 and the guide circular table surface 411. During the specific implementation process, before the device is started, the grinding ring 444 is raised or lowered by adjusting the second threaded rod 445 to adjust the distance between the grinding ring 444 and the second grinding disc 42, so that the grain fragments can be ground between the first grinding disc 41 and the second grinding disc 42 according to the required particle size requirements to obtain grain fragments of corresponding sizes, thereby improving the efficiency of grain grinding.

[0085] Reference Fig.10 In order to prevent the grain particles from clumping together due to the presence of moisture and to classify the grain particles, a second cavity 7 is provided between the barrel shell 1 and the first cavity 6, and the grinding block 443, the threaded box 441, the first threaded rod 442 and the grinding wall 43 are all in the second cavity 7.

[0086] A plurality of hot air holes 71 are provided at the bottom of the second cavity 7 , and a discharge pipe 72 is provided at one side of the top of the second cavity 7 .

[0087] Among them, the aperture of the hot air hole 71 is smaller than the particle size of the grain particles. During the specific implementation process, a blower is connected to the bottom of the cylinder shell 1 to blow hot air into the cylinder shell 1. By adjusting the wind force, the grain particles can be graded. The hot air enters the second cavity 7 through the hot air hole 71, and blows up the grain particles that meet the requirements after being ground by the first grinding disc 41 and the second grinding disc 42. At the same time, these grain particles are dried to prevent them from agglomerating and affecting the quality of the grain. The grain particles blown up by the hot air are finally discharged through the discharge pipe 72 and collected by the collecting device, while the grain particles that are not blown up by the hot air continue to be ground between the grinding wall 43 and the grinding block 443 until the ground grain particles can be blown up by the hot air, that is, the particle size meets the required requirements.

[0088] The implementation principle of the present invention is:

[0089] 1: Before the machine is operated, the size adjustment component 44 is adjusted according to the grain size so that the distance between the first grinding disc 41 and the second grinding disc 42 and the distance between the first grinding disc 41, the second grinding disc 42 and the grinding wall 43 meet the required grain size standard.

[0090] 2: Grains are fed into the cylinder shell 1 through the feeding component 2. After being dispersed by the feeding component 2, the grains can be evenly dispersed in the cylinder shell 1. During the falling process, the rotating crushing blade 31 crushes the grains. Grain fragments that meet the requirements will fall from the constantly vibrating screen 32 into the grinding component 4 at the bottom of the cylinder shell 1 for grinding. Grain fragments that do not meet the size will continue to be crushed by the crushing blade 31 until the grain fragments can pass through the screen 32 and fall into the grinding component 4.

[0091] 3: The grain fragments fall between the first grinding disc 41 and the second grinding disc 42. Under the action of centrifugal force, the grain fragments move toward the inner wall of the cylinder shell 1. During the movement, the grain fragments are ground between the first grinding disc 41 and the second grinding disc 42. Since the first grinding disc 41 and the second grinding disc 42 rotate in opposite directions, the grain fragments can be ground more fully and evenly with the cooperation of the two. Under continuous grinding, the particle size of the grain particles will continue to decrease until it becomes the required particle size. When the grain fragments reach the edge of the first grinding disc 41 and the second grinding disc 42, the hot air force blown out by the drying facility can be adjusted to blow up the grain fragments that meet the requirements, and these grain fragments are sent out of the cylinder shell 1 and then collected by a collecting device.

[0092] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
