Description

Technical Field

[0001] This invention relates to the field of oat gene extraction technology, specifically to an oat seed grinding device for oat gene extraction. Background Technology

[0002] With the continuous development of the bio-breeding and gene testing industry, scientific research on oat germplasm resources, including screening, identification, gene sequencing, and gene cloning, is deepening. Related testing and experimental projects are gradually being carried out routinely. As the core raw material for various gene extraction experiments, the effect of the initial crushing and grinding of oat seeds directly determines the purity, integrity, and overall experimental efficiency of subsequent gene extraction. To ensure accurate and reliable gene testing results, oat seeds must be thoroughly and uniformly ground. Therefore, the industry needs high-performance and stable dedicated oat seed grinding equipment to efficiently complete the pretreatment of experimental samples.

[0003] However, in the existing grinding equipment, oat seeds are prone to bridging and clogging inside the hopper, which can easily cause interruptions in material feeding and discontinuous feeding. This requires frequent manual clearing, which not only increases the number of operating procedures but also interrupts the continuous operation of the equipment, reduces the stability of the equipment, and seriously affects the orderly development of subsequent grinding processes, thus restricting the efficiency and continuity of the overall grinding operation. Summary of the Invention

[0004] The purpose of this invention is to provide an oat seed grinding device for oat gene extraction. By setting up a feeding section, it solves the problem that in existing grinding devices, oat seeds are prone to bridging and clogging inside the feeding hopper, which easily causes interruption of material feeding and discontinuous feeding. This requires frequent manual clearing, which not only increases the operation steps but also interrupts the continuous operation of the device, reduces the stability of the device, and seriously affects the orderly development of subsequent grinding processes, thus restricting the overall grinding efficiency and continuity.

A transmission component is provided on the rotating shaft II. The grooved transmission rod is grooved in shape. The transmission component includes a transmission rod fixedly connected to the outer wall of the rotating shaft II. A cylindrical rod is fixedly connected to the bottom of the transmission rod. The cylindrical rod is located inside the grooved transmission rod and is located on the side of the bottom of the transmission rod away from the rotating shaft II.

[0010] Furthermore, the striking assembly includes a plurality of hollow cylindrical blocks fixedly connected to the inner wall of the conical hopper. A circular limiting plate is slidably connected inside each of the hollow cylindrical blocks. A striking rod is fixedly connected to one side of each of the circular limiting plates that are close to each other.

Elastic elements are provided on the hollow cylindrical blocks. Eight hollow cylindrical blocks are provided.

[0011] Furthermore, the extrusion assembly includes a plurality of extrusion protrusions fixedly connected to the outer wall of the conical hopper; eight extrusion protrusions are provided.

[0012] Furthermore, the grinding assembly includes a grinding ring fixedly connected to the inner wall of the grinding barrel, a cylindrical block is disposed inside the grinding ring, and several grinding wheels are fixedly connected to the outer wall of the cylindrical block; the grinding ring is divided into four grinding zones, and the four grinding wheels are grinding wheels with four different coefficients, and the grinding becomes finer from top to bottom; the top of the grinding ring is an inward inclined slope, and the top of the cylindrical block is an outward inclined slope.

[0013] Furthermore, the power assembly includes a second motor fixedly connected to the inner wall of the bottom of the base, and the output shaft of the second motor is fixedly connected to a third rotating shaft via a coupling. The top of the third rotating shaft extends into the grinding barrel, and the third rotating shaft is rotatably connected to the grinding barrel. The top of the third rotating shaft is fixedly connected to a cylindrical block.

[0014] The present invention has the following beneficial effects:

[0015] (1) By setting up a feeding section, oat seeds are put into the feeding hopper. The seeds slide down through the first conical feeding hopper and the inclined ring to the second conical feeding hopper and finally enter the grinding barrel. After starting the first motor, the power is transmitted through the second rotating shaft, the transmission rod and the cylindrical rod, which drives the grooved transmission rod and the first rotating shaft to make forward and reverse reciprocating motion. The first rotating shaft drives the second conical feeding hopper and the corrugated protrusions on its surface to swing back and forth with the help of the cross bracket, which guides the material to fall down and effectively prevents the oat seeds from bridging and blocking inside the second conical feeding hopper. This ensures that the seeds can fall into the grinding barrel continuously and smoothly, making the material feeding process continuous and stable. There is no need for manual material clearing, which simplifies the operation process, improves the overall stability and continuity of the device, and also ensures that the subsequent grinding process can be carried out in an orderly manner.

[0016] (2) By setting a striking part, when the conical feeding hopper 2 rotates, the extrusion protrusion on it extrudes the striking rod, and the striking rod drives the circular limit plate to compress the spring. After the extrusion is released, the spring rebounds, pushes the striking rod to reset and strikes the conical feeding hopper 2. The cycle operation makes it continuously vibrate. The vibration generated by the continuous striking further breaks the problem of material accumulation and bridging, making the oat seeds feed more smoothly, improving the continuity and reliability of feeding, and reducing the situation of equipment downtime for cleaning.

[0017] (3) By setting up a grinding section, starting motor 2, and driving the cylindrical block and grinding wheel to rotate via rotating shaft 3, the oat seeds falling from conical hopper 1 and conical hopper 2 fall onto the top of the cylindrical block. Under the action of centrifugal force and inclined plane, they enter between the grinding wheel and grinding ring. After multi-stage grinding, the oat powder flows along the inclined plane at the bottom of the grinding barrel to the discharge pipe and is discharged. The multi-stage grinding method can make the oat seeds more fully and evenly crushed, ensuring the grinding quality and meeting the material requirements for gene extraction.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] Please see Figures 1-10 As shown, the present invention is an oat seed grinding device for oat gene extraction, including a base 111 and a grinding barrel 112 fixedly connected to the top of the base 111.

By setting the striking part 3, the vibration generated by continuous striking further breaks the problem of material accumulation and bridging, making the oat seeds feed more smoothly, improving the continuity and reliability of feeding, and reducing the need for equipment downtime for maintenance.

[0036] The grinding unit 4 includes a grinding assembly 41 disposed inside a grinding barrel 112; and a power assembly 42 mounted on the grinding barrel 112. The grinding assembly 41 includes a grinding ring 411 fixedly connected to the inner wall of the grinding barrel 112. A cylindrical block 412 is disposed inside the grinding ring 411, and several grinding wheels 413 are fixedly connected to the outer wall of the cylindrical block 412. The grinding ring 411 is divided into four grinding zones, and the four grinding wheels 413 are grinding wheels with four different coefficients, grinding finer from top to bottom. The top of the grinding ring 411 is inclined inward. The top of the cylindrical block 412 is an outwardly inclined slope. The power assembly 42 includes a second motor 421 fixedly connected to the inner wall of the bottom of the base 111. The output shaft of the second motor 421 is fixedly connected to a third rotating shaft 422 via a coupling. The top of the third rotating shaft 422 extends into the grinding barrel 112 and is rotatably connected to the grinding barrel 112. The top of the third rotating shaft 422 is fixedly connected to the cylindrical block 412. By setting the grinding section 4, the multi-stage grinding method can make the oat seeds more thoroughly and evenly crushed, ensuring the grinding quality and meeting the material requirements for gene extraction.

[0037] It should be noted that both motor 225 and motor 421 in this application can be automatically controlled by inputting relevant parameters according to the program set in the control panel. The setting of this control method can be achieved by existing technology, such as PLC.

[0038] In use, oat seeds are poured into conical hopper 1 211 through feed hopper 215. Under the action of inclined ring 213, the oat seeds slide into conical hopper 212. The oat seeds slide through the bottom of conical hopper 212 and the bottom of conical hopper 1 211 into grinding barrel 112. Motor 1 225 is started. Motor 1 225 drives the cylindrical rod 228 on transmission rod 227 to move through rotating shaft 226. The cylindrical rod 228 moves in a circle around rotating shaft 226. At this time, the cylindrical rod 228 pushes the grooved transmission rod 223 through the groove on the grooved transmission rod 223. 3. Movement: The grooved transmission rod 223 drives the rotating shaft 222 to rotate. Under the action of the transmission rod 227 and the grooved transmission rod 223, the rotating shaft 222 moves back and forth. At this time, the rotating shaft 222 drives the conical feeding hopper 212 to rotate inside the conical feeding hopper 211 through the cross bracket 221. The conical feeding hopper 212 drives several corrugated protrusions 214 to swing back and forth, causing the oat seeds in the conical feeding hopper 212 to shake, avoiding the phenomenon of bridging in the conical feeding hopper 212, and ensuring that the oat seeds enter the grinding barrel 112 smoothly.

[0039] During the rotation of the conical hopper 212, the eight extrusion protrusions 321 extrude eight striking rods 313, causing the striking rods 313 to move away from each other. The striking rods 313 push the circular limiting plate 312 to extrude springs 314, causing deformation and generating elastic force. When the extrusion protrusions 321 pass the striking rods 313, the extrusion force on the springs 314 disappears, releasing the elastic force. The elastic force acts on the circular limiting plate 312, which pushes the striking rods 313 to quickly return to their original position and strike the conical hopper 212. This process is repeated to strike the conical hopper 212, causing it to vibrate and further preventing bridging of oat seeds inside the conical hopper 212.

[0040] During this process, motor 2 421 is started. Motor 2 421 drives the four grinding wheels 413 on the cylindrical block 412 to rotate via shaft 3 422. Oat seeds falling through conical hoppers 1 211 and 2 212 land on the top of the cylindrical block 412. The oat seeds slide down between the cylindrical block 412 and the grinding ring 411 under the action of centrifugal force and the inclined surface at the top of the cylindrical block 412. At this time, the grinding wheels 413 located above cooperate with the grinding ring 411 to perform the first grinding of the oat seeds. After being ground once, the oat seeds slide between the second grinding wheel 413 and the grinding ring 411 for a second grinding. Then, they slide between the third grinding wheel 413 and the grinding ring 411 for a third grinding. After the third grinding, the oat seeds slide between the bottom grinding wheel 413 and the grinding ring 411 for a final grinding. This process of multi-stage grinding of the oat seeds results in oat flour that slides down the inclined surface at the bottom of the grinding drum 112 to the discharge pipe 113 and is then discharged through the discharge pipe 113.
