Description

Technical Field

[0001] The invention relates to the technical field of seed processing, in particular to an adaptive seed grinding machine. Background Art

[0002] Seed peeling machines are usually used in agricultural breeding and food processing. Compared with food processing, agricultural breeding has higher requirements for seed peeling and the processing volume is usually smaller. Therefore, a small seed peeling machine is used for peeling operations.

[0003] At present, the seed grinding machines available on the market, such as the seed grinding machine disclosed in patent CN214800640U, are provided with a grinding disc in the seed box of the seed box, and a grinding assembly is provided above the seed box. The grinding assembly is threadedly connected to the seed box to form a combined device, and a grinding chamber is provided in the combined device, through which the seed material is ground. At the same time, a driving member is provided at the end of the grinding assembly on the opposite side of the seed box, and the driving member is transmission-connected to the grinding assembly. At the same time, a blowing assembly is provided on the outside of the combined device, and the two ends of the blowing assembly are respectively connected to the grinding assembly and the seed box to introduce the airflow into the grinding chamber, and the top cover is threadedly connected to the seed box, so that when in use, the distance between the flow-increasing grinding disc and the grinding disc can be adjusted according to the particle size of the seed material, thereby adapting to the specifications of the seed material and meeting the use requirements of grinding different seed material particle sizes. Although the above structure can meet the needs of seed grinding, the rotation speed of the grinding disc and the force of the grinding disc contacting the seed material will affect the grinding effect during grinding. Moreover, when the motor rotates at high speed, if the force of the grinding disc contacting the seed material is large, it will easily lead to excessive grinding. If the motor runs at low speed, when the force of the grinding disc contacting the seed material is small, it will lead to insufficient grinding. Moreover, as the seed grinding time progresses, the seed coat of the seed gradually becomes thinner. If the force of the grinding disc contacting the seed material is still maintained at a large level, the problem of excessive grinding will easily occur. Moreover, as the seed coat gradually becomes thinner, the rotation speed of the grinding disc remains unchanged, which will affect the grinding efficiency and be time-consuming and labor-intensive. Therefore, the existing seed grinding machine will lead to the problem of poor grinding effect and reduced grinding efficiency due to the factors such as the inability to adjust the rotation speed of the grinding disc in real time during operation and the inability to adjust the contact force on the seed material.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To the attached Figure 4 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0019] Figure 1A structural diagram of an embodiment of an adaptive seed peeling machine of the present invention; Figure 2 1 is a cross-sectional view of an adaptive seed grinding machine of the present invention. Figure 1 and Figure 2 As shown, the adaptive seed grinding machine provided in this embodiment includes: a main unit 1, a seed box 2, a speed-adjustable main grinding disc 3, a floating secondary grinding disc 4, and a variable speed movable member 6. An upper chamber 11 is provided at one end of the main unit 1 to facilitate the subsequent accommodation of the speed-adjustable main grinding disc 3 and placement of seeds to be ground. The seed box 2 is then removably mounted on the end of the main unit 1 with the upper chamber 11, achieving a removable connection between the seed box 2 and the main unit 1, facilitating the subsequent placement of seeds to be ground into the seed box 2 or removal of ground seeds. Furthermore, a motor 12 is provided within the main unit 1, with a drive shaft 121 extending into the upper chamber 11. Preferably, the motor 12 is a permanent magnet synchronous motor 12 capable of adjusting the speed by adjusting the current, facilitating the initial low-speed and subsequent high-speed operation during the grinding process. Furthermore, a lower chamber 21 is provided on the side of the seed box 2 connected to the main unit 1, providing a workpiece for the installation of the floating secondary grinding disc 4 and the placement of seeds. The lower chamber 21 is connected to the upper chamber 11 to form a grinding chamber, so that the seeds can be ground in the grinding chamber, and the structural design is more reasonable.

[0020] Specifically, the speed-regulating main grinding disc 3 is installed on the drive shaft 121 extending from the motor 12 to the upper cavity 11, so that when the motor 12 is running, it can drive the speed-regulating main grinding disc 3 to rotate through its drive shaft 121, thereby meeting the demand for grinding the seeds located in the grinding cavity.

[0021] Specifically, the floating secondary grinding disc 4 is mounted in the lower chamber 21 and moves axially along the drive shaft 121 of the motor 12, allowing for adjustment of the spacing between the floating secondary grinding disc 4 and the speed-regulating primary grinding disc 3. The floating secondary grinding disc 4 comprises a floating frame 41 and a lower grinding disc 42. The floating frame 41 is slidably disposed within the lower chamber 21 along the drive shaft 121 of the motor 12, allowing for the floating frame 41 to slide. Furthermore, a floating spring 43 is provided between the floating frame 41 and the seed box 2. This supports the floating frame 41, allowing it to slide and, through the lower grinding disc 42, allow the floating frame 41 to act on the seeds, thereby grinding the seeds. Furthermore, a trigger portion 5 extending toward the main machine 1 is provided at one end of the floating frame 41 facing the main machine 1. This allows the trigger portion 5 to automatically adjust the contact force with the seeds according to the rotational speed when the seed box 2 is subsequently installed on the main machine 1. In addition, the lower grinding disc 42 is installed on the floating frame 41, so that the floating frame 41 can drive the lower grinding disc 42 to move axially along the drive shaft 121, thereby adjusting the distance between the lower grinding disc 42 and the speed regulating main grinding disc 3, thereby adjusting the size of the force of contacting the seed to adapt to different processing requirements.

[0022] Figure 3 for Figure 2 An enlarged view of part A in the figure. Figure 2 and Figure 3Shown, the speed change moving part 6 is arranged in the main frame 1, at this moment, the speed change moving part 6 comprises blade 61, deformation membrane 62, trigger block 63 and pushes against spring 64 again, and, in the main frame 1, be provided with air cavity 13, blade 61 and generation air flow are installed by air cavity 13.In addition, the drive shaft 121 of motor 12 is extended in the lower chamber 21 after passing air cavity 13, and blade 61 is installed on one section that drive shaft 121 is positioned in the air cavity 13, make motor 12 can drive blade 61 rotations simultaneously when rotating, and the rotating speed of blade 61 follows the variation of the rotating speed of motor 12 and changes, and the wind pressure that produces also can change, for follow-up action is in floating frame 41 slippages and condition is provided.In addition, between air cavity 13 and the slip chamber, be provided with sliding hole 14, and trigger block 63 is slidably arranged in the sliding hole 14, for trigger block 63 is provided motion-guided by sliding hole 14. Furthermore, the deformable membrane 62 is positioned near the opening of the air cavity 13 in the sliding hole 14 and abuts against the trigger block 63. This allows the deformable membrane 62 to deform synchronously when the wind pressure in the air cavity 13 changes, thereby changing the force exerted by the deformable membrane 62 on the trigger block 63. This in turn alters the travel of the trigger block 63 within the sliding hole 14, thus providing conditions for subsequently driving the floating frame 41 to move. At the same time, a push spring 64 is provided between the side of the trigger block 63 facing away from the deformable membrane 62 and the main unit 1. This push spring 64 can push the trigger block 63 toward the side of the deformable membrane 62. That is, after the force exerted by the deformable membrane 62 on the trigger block 63 decreases, the push spring 64 can automatically push the trigger block 63 back to its original position, thereby enabling the floating frame 41 to be reset, resulting in a more reasonable structural design. When the motor 12 rotates at a high speed, the movement stroke of the trigger block 63 increases, the thrust on the trigger part 5 becomes larger, and the lower grinding disc 42 on the floating frame 41 moves in a direction away from the speed regulating main grinding disc 3, so that the force of contacting the seeds becomes smaller, thereby meeting the use requirement of high-speed and low-force skin grinding, which can improve the skin grinding effect and improve the skin grinding efficiency.

[0023] More specifically, the sliding hole 14 for the sliding of the trigger block 63 is a variable-section hole. At this time, the sliding hole 14 includes a first sliding cavity 141 and a second sliding cavity 142, and the inner diameter of the first sliding cavity 141 is larger than the inner diameter of the second sliding cavity 142. At the same time, the first sliding cavity 141 is connected to the wind cavity 13, and the deformable membrane 62 is arranged at the cavity mouth of the first sliding cavity 141, so that the deformable membrane 62 is arranged at one end of the large-section hole mouth of the sliding hole 14, so that when the pressure in the wind cavity 13 changes, the deformable cavity can be more easily deformed by the pressure change, making it more sensitive to the action of the trigger block 63. In addition, the trigger block 63 further includes a mating end 631 and a triggering end 632. The diameter of the mating end 631 is set to be larger than the diameter of the triggering end 632. The mating end 631 and the triggering end 632 are respectively slidably disposed within the first sliding cavity 141 and the second sliding cavity 142, so that the mating end 631 and the triggering end 632 can slide within the first sliding cavity 141 and the second sliding cavity 142, respectively. At the same time, the mating end 631 and the triggering end 632 can be prevented from escaping from one end of the second sliding cavity 142, thereby improving the stability of the trigger block 63 installed in the sliding hole 14. In addition, a push spring 64 is mounted on the outside of the trigger block 63, with its two ends respectively resting on the bottom of the first sliding cavity 141 and the mating end 631. When the force exerted by the deformable membrane 62 on the trigger block 63 decreases, the trigger block 63 can automatically reset under the action of the push spring 64, thereby reducing the force exerted by the trigger block 63 on the trigger portion 5 of the floating frame 41, thereby meeting the requirements for the movement of the floating frame 41. It is worth noting that because the inner diameter of the end of the slide hole 14 near the air cavity 13 is larger, while the inner diameter of the end engaging the trigger portion 5 is smaller, under the condition of constant wind pressure at both ends of the slide hole 14, the force acting on the trigger block 63 near the air cavity 13 is greater than the force acting on the end engaging the trigger portion 5. This results in a smaller impact of wind pressure changes within the microdermabrasion chamber on the trigger block 63, thereby ensuring smooth movement of the trigger block 63 and thereby pushing the floating frame 41. Furthermore, the airflow generated within the air cavity 13 also serves as the subsequent airflow blowing into the microdermabrasion chamber, blowing away the dandruff and improving the microdermabrasion effect.

[0024] More specifically, the floating frame 41 is arranged in a barrel shape, and a plurality of sliders 411 are provided on the outer wall of the floating frame 41. Preferably, the sliders 411 and the floating frame 41 are an integral structure. At the same time, a plurality of slide grooves 22 corresponding to the sliders 411 are provided on the side wall of the lower chamber 21 of the seed box 2 along the axial direction of the drive shaft 121 of the motor 12. This allows the floating frame 41 to slide stably along the axial direction of the drive shaft 121 of the motor 12 under the cooperation of the sliders 411 and the slide grooves 22. While the floating frame 41 drives the lower grinding disc 42 to move, the structural stability is maintained, thereby ensuring the grinding effect. It is worth noting that a floating spring 43 is provided in the lower chamber 21 of the seed box 2, and the two ends of the floating spring 43 respectively abut against the barrel bottom of the floating frame 41 and the cavity bottom of the lower chamber 21 of the seed box 2, so that the floating spring 43 can push the floating frame 41 to reset.

[0025] Figure 4 for Figure 2 An enlarged view of part B in the figure. Figure 2 and Figure 4 As shown, a fixed shaft 44 is positioned within the barrel cavity of the floating frame 41, centered at the bottom of the barrel. It is arranged axially along the drive shaft 121 of the motor 12. One end of the fixed shaft 44 is movably mounted on the floating frame 41, allowing it to move relative to the floating frame 41. An adjustment member 45 is positioned between the end of the fixed shaft 44 that is movably mounted on the floating frame 41 and the floating frame 41, allowing the position of the fixed shaft 44 on the floating frame 41 to be adjusted. Furthermore, a lower grinding disc 42 is mounted on the fixed shaft 44 and positioned within the barrel cavity of the floating frame 41. This allows the lower grinding disc 42 to move with the floating frame 41 as a whole, while also being able to move relative to the floating frame 41 under the control of the adjustment member 45. This allows for multiple adjustments to the position of the lower grinding disc 42, enhancing adaptability. It is worth noting that an adjustment hole is provided on the seed box 2, directly opposite the adjustment member 45, allowing the operator to adjust the adjustment member 45 through the adjustment hole, which makes the structural design more reasonable. In addition, in the initial state, the adjustment member 45 can be adjusted according to the particle size of the seeds, so that the spacing between the lower grinding disc 42 and the speed-regulating main grinding disc 3 can meet the grinding requirements of different seeds. During the grinding process, the floating frame 41 can be moved to adapt to the grinding requirements at different speeds, thereby meeting the grinding requirements while improving the grinding effect and efficiency.

[0026] More specifically, the adjusting member 45 for adjusting the installation position of the fixed shaft 44 on the floating frame 41 includes a screw 451 and a pressing plate 452. One end of the screw 451 is fixedly connected to one end of the fixed shaft 44 and is coaxially arranged, so that the screw 451 is used as an extension rod of the fixed shaft 44. At the same time, an adjusting screw hole 413 is provided on the floating frame 41, and the screw 451 is threadedly connected to the adjusting screw hole 413. In addition, a straight or cross-shaped hole is provided on the end of the screw 451 facing away from the fixed shaft 44, which is convenient for a screwdriver to twist the screw 451, thereby adjusting the position of the fixed shaft 44 on the floating frame 41. Furthermore, one end of a pressing plate 452 is screwed to the floating frame 41, and the other end of the pressing plate 452 presses against the end of the screw 451 facing away from the fixed shaft 44. This allows the pressing plate 452 to compress the screw 451 after the fixed shaft 44 is adjusted, preventing the fixed shaft 44 from rotating during microdermabrasion, thereby maintaining the stability of the fixed shaft 44 during use. It is worth noting that the screw 451 and the fixed shaft 44 are injection molded, providing improved integrity and a stronger connection.

[0027] More specifically, a connecting hole 441 is provided on the end face of the fixed rotating shaft 44 at one end of the barrel inner cavity of the floating frame 41. At the same time, a through hole is provided in the center of the lower grinding disc 42. A screw passes through the through hole and is connected to the connecting hole 441, so that the lower grinding disc 42 is installed on the fixed rotating shaft 44 by the screw, thereby facilitating the disassembly and assembly of the lower grinding disc 42 on the fixed rotating shaft 44, thereby facilitating the subsequent rapid replacement of the lower grinding disc 42 after the lower grinding disc 42 is worn.

[0028] More specifically, the sidewalls of the floating frame 41 are formed by a plurality of struts 412, with spaces between adjacent struts 412. This allows scraping and other debris to be blown away through the spaces between the struts 412, further enhancing the resurfacing effect. Furthermore, one or more struts 412 are provided with a trigger 5, which acts on the floating frame 41 to move it. It is worth noting that, since existing seed resurfacing machines already have an air blowing mechanism that also acts on the resurfacing chamber, this is state-of-the-art technology. Therefore, the air blowing mechanism will not be further described here.

[0029] More specifically, the trigger portion 5 is a rod arranged axially along the drive shaft 121 of the motor 12, allowing movement of the trigger portion 5 to smoothly change the gap between the lower grinding disc 42 and the speed-regulating main grinding disc 3. One end of the trigger portion 5 is fixedly connected to the floating frame 41, ensuring that the trigger portion 5 can smoothly drive the floating frame 41 to move. Furthermore, the other end of the trigger portion 5 extends into the second sliding cavity 142 and abuts against the trigger end 632, allowing the trigger block 63 to push the trigger portion 5 through the trigger end 632 during sliding, thereby achieving movement of the floating frame 41. Furthermore, since the trigger portion 5 extends into the second sliding cavity 142, the second sliding cavity 142 guides the movement of the trigger portion 5, thereby guiding the movement of the floating frame 41, improving the stability of the floating frame 41 during movement. Furthermore, the trigger portion 5 blocks the second sliding cavity 142, preventing dandruff from entering the second sliding cavity 142 and causing problems such as jamming, resulting in a more rational structural design.

[0030] More specifically, a plurality of chip removal holes 23 are provided on the outer wall of the seed box 2, and the chip removal holes 23 are connected to the lower cavity 21, so that the dandruff generated during the skin grinding process can be blown out from the chip removal holes 23, reducing the impact of the dandruff on the skin grinding and improving the skin grinding effect.

[0031] More specifically, a card slot 15 is provided on the outer side wall of the main machine 1 with one end of the upper chamber 11. The card slot 15 is an L-shaped slot. One section of the card slot 15 is arranged axially along the drive shaft 121 of the motor 12, and the other section of the card slot 15 is arranged circumferentially along the drive shaft 121 of the motor 12, so that the card slot 15 has two sections of slots arranged in different directions. At the same time, a card block 24 corresponding to the card slot 15 is provided on the inner side wall of the lower chamber 21 of the seed box 2, so that when the seed box 2 is installed on the main machine 1, it is only necessary to insert the card block 24 into one end of the card slot 15 arranged axially along the drive shaft 121 of the motor 12 and move it to the other section of the card slot 15, and then screw the seed box 2 at a predetermined angle, so that the card block 24 is inserted into a section of the card slot 15 arranged circumferentially along the drive shaft 121 of the motor 12, thereby realizing the card connection of the seed box 2 on the main machine 1, making disassembly and assembly more convenient and facilitating the taking and placing of seeds.

[0032] The adaptive seed grinding machine provided by this embodiment includes a main body 1, a seed box 2, a speed-regulating main grinding disc 3, a floating auxiliary grinding disc 4 and a speed-changing moving part 6; the seed box 2 is removed and installed on the main body 1, and the speed-regulating main grinding disc 3 is installed on the driving shaft 121 of the motor 12 in the main body 1, and the floating auxiliary grinding disc 4 is installed in the seed box 2 and arranged opposite to the speed-regulating main grinding disc 3. At the same time, a trigger part 5 extending toward the main body 1 is provided on the floating auxiliary grinding disc 4, and the main body 1 is provided with a speed-regulating moving part 6 that changes with the speed change of the driving shaft 121 of the motor 12, and the trigger block 63 of the speed-regulating moving part 6 abuts against the trigger part 5, which can control the floating auxiliary grinding disc 4 to approach the speed-regulating main grinding disc 3 when the motor 12 rotates at a low speed, and control the floating auxiliary grinding disc 4 to stay away from the speed-regulating main grinding disc 3 when the motor 12 rotates at a high speed, thereby realizing low-speed high-force grinding and high-speed small-force grinding, improving the grinding efficiency and the grinding effect while avoiding excessive seed grinding.
