Description

Technical Field

[0001] The invention relates to the field of biological experiment material grinding, in particular to a biological experiment material grinding device. Background Art

[0002] Biological experiment refers to the process of purposefully observing and studying the structure and life activity phenomena of organisms that are difficult to observe under normal circumstances by using certain instruments, materials and drugs under specific environmental conditions and scientific methods. Biological materials include animal materials and plant materials, and biological experimental materials need to be ground before the experiment.

[0003] However, the grinding methods for biological experimental materials are all carried out by grinding devices, basically through oscillation grinding and grinding disc methods. Grinding is the process of crushing and homogenizing biological materials for subsequent extraction, separation, purification and other operations of animal and plant materials. In biological experiments, animal muscle tissue, connective tissue, bone tissue, hair tissue, etc., plant roots, stems, leaves, seeds, etc. all need to be ground to facilitate further analysis and research.

[0004] In the prior art, biological experimental materials need to be ground into particles by experimenters according to the experimental requirements. Generally speaking, all grinding devices grind biological experimental materials according to the experimental requirements, that is, the biological experimental materials are divided into different grinding devices according to their humidity, hardness, etc., and the biological experimental materials are ground by the grinding devices.

[0005] In order to deal with this situation, each manufacturer generally produces different grinding discs, that is, different biological experiment materials are ground by different grinding discs. However, when grinding biological experiment materials, it is necessary to get the biological experiment materials, select different grinding devices according to the characteristics of the biological experiment materials, and then grind the biological experiment materials by the grinding devices.

[0006] As we all know, biological experimental materials are divided into animal materials and plant materials. The muscle tissue and connective tissue in animal materials contain a lot of water, while the bone tissue in animal materials is harder. Secondly, the muscle tissue, connective tissue and hair tissue in animal materials contain more protein. Therefore, it is necessary to select grinding discs with different degrees of roughness according to the characteristics of biological experimental materials, and control the grinding pressure. At the same time, it is necessary to control the grinding temperature according to whether the biological experimental materials contain protein.

[0007] After massive searches, it was found that the prior art publication number is CN218132096U, which discloses a device for grinding experimental materials for biological experiments, characterized in that: it includes a conical grinding wheel and a conical grinding disc coaxially matched from top to bottom; the lower part of the conical grinding disc is fixedly connected to a vertical threaded rod, and the lower end of the threaded rod is fixedly connected to a turntable; the threaded rod is engaged with a mounting block, and the mounting block is fixed; the conical grinding wheel is fixed, and the conical grinding disc can move up and down driven by the threaded rod as the turntable rotates.

[0008] Therefore, based on the above search and in combination with the existing grinding methods, only the particle size of the ground biological experimental materials can be controlled, and it is impossible to select grinding discs with different roughness according to the different biological experimental materials, and it is impossible to control the temperature during the grinding process according to whether the biological experimental materials contain protein. This can easily lead to an increase in the grinding time of the biological experimental materials, and it can easily lead to thermal denaturation of the protein in the biological experimental materials at high temperatures, and its structure will change. Based on the above problems, the present application proposes a biological experimental material grinding device. Summary of the invention

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a biological experiment material grinding device.

[0039] In a typical implementation of the present application, Figure 1-5 As shown, a biological experiment material grinding device comprises a grinding box 1, a box cover is overlapped on the top of the grinding box 1, a controller 2 is fixedly arranged on the top of the box cover, and a pull-out grinding box 3 is installed inside the grinding box 1 for placing the ground biological experiment materials;

[0040] The grinding component 4 is installed inside the grinding box 1 and is used to grind biological experimental materials. The grinding component 4 includes a hollow shaft 41 rotatably installed inside the box cover. A grinding drive 413 is arranged on the surface of the hollow shaft 41. A double-channel rotary joint 42 is fixedly installed on the top of the hollow shaft 41 through a flange. A mounting seat 43 is fixedly arranged at the bottom of the hollow shaft 41. An L-shaped mounting column 44 is rotatably arranged inside the mounting seat 43. A rotation locking member 414 is arranged between the mounting seat 43 and the L-shaped mounting column 44. A cooling box 45 is fixedly arranged at the bottom of the L-shaped mounting column 44. A water inlet hose 46 and a water outlet hose 47 are connected between the cooling box 45 and the double-channel rotary joint 42. The cooling box A fine grinding disc 48 is fixedly arranged at the bottom of 45, and the water inlet hose 46 and the water outlet hose 47 have the same diameter. The upper half of the water inlet hose 46 and the water outlet hose 47 are both located inside the hollow rotating shaft 41. A wireless temperature sensor 415 is fixedly arranged on the top of the fine grinding disc 48. A circular frame is fixedly arranged on the upper side wall of the cooling box 45. The wireless temperature sensor 415 is located inside the circular frame. The circular frame is used to prevent the cooling water from contacting the wireless temperature sensor 415. The circular frame can prevent the cold water from contacting the wireless temperature sensor 415, thereby avoiding the damage of the wireless temperature sensor 415 due to water ingress. Secondly, it avoids the influence of the cooling water on the detection structure of the wireless temperature sensor 415. The right end of the L-shaped mounting column 44 is fixed A fixed plate 49 is fixedly provided, and a connecting column 410 is slidably provided inside the fixing plate 49, and a coarse grinding disc 411 is fixedly provided at the bottom of the connecting column 410. The number of the connecting column 410 and the fixing plate 49 is four, and the four connecting columns 410 and the four fixing plates 49 are all distributed in a circular array. The fixing plate 49 is made of high-carbon steel. Through the four connecting columns 410 and the four fixing plates 49, the coarse grinding disc 411 can be kept horizontal after installation, thereby avoiding the coarse grinding disc 411 from tilting and colliding with the pull-out grinding box 3, and avoiding the coarse grinding disc 411 from falling due to the breakage of the connecting column 410. A pressure spring 412 is connected between the coarse grinding disc 411 and the fixing plate 49. By The grinding disc 48 and the coarse grinding disc 411 rotate, and the fine grinding disc 48 or the coarse grinding disc 411 can be selected to grind the biomaterial. Different grinding discs can be selected according to the humidity, hardness and adhesion of the biomaterial. The heat generated by the friction between the grinding disc and the biomaterial can be detected, and the grinding disc can be cooled according to the detected structure, thereby avoiding the influence of temperature on the biomaterial containing protein. The pressure spring 412 is compressed so that the pressure spring 412 gives a downward thrust to the coarse grinding disc 411, thereby increasing the grinding force of the coarse grinding disc 411 on the bone and accelerating the grinding speed of the coarse grinding disc 411 on the bone.

[0041] It is worth mentioning that the wireless temperature sensor 415 mentioned above consists of three parts: a control unit, wireless data transmission and temperature measurement. After temperature measurement, the temperature data is transmitted to the temperature measurement control end wirelessly. Therefore, the wireless temperature sensor 415 is an existing mature technical structure, so the present invention will not be described in detail.

[0042] The lifting component 5 is installed at the rear side of the grinding box 1 and is used to move the fine grinding disc 48 and the coarse grinding disc 411 out of the grinding box 1, so as to facilitate the rotation of the positions of the fine grinding disc 48 and the coarse grinding disc 411.

[0043] It is worth mentioning that during the grinding process of the biological test material, if the temperature of the fine grinding disc 48 cannot be reduced after the cooling water enters, the grinding drive 413 is controlled by the controller 2 to stop, thereby avoiding the destruction of the protein of the biological test material due to excessive temperature.

[0044] As a preferred implementation in this embodiment, refer to Figure 6 The grinding drive member 413 includes a driving motor 4131 arranged on the top of the box cover, a driving gear 4132 is fixedly arranged at the output end of the driving motor 4131, a driven gear 4133 is meshed with the left side of the driving gear 4132, and the driven gear 4133 is fixedly installed on the hollow rotating shaft 41. The driving motor 4131 drives the driven gear 4133 to rotate through the driving gear 4132, and drives the grinding component 4 to grind the biological test material through the driven gear 4133. When the temperature rises during the grinding process, the driving motor 4131 can be stopped to stop the driving gear 4132 and the driven gear 4133, so that the grinding component 4 can be stopped.

[0045] As a preferred implementation in this embodiment, refer to Figure 7The rotary locking member 414 includes a metal locking pin 4141 slidably arranged inside the mounting seat 43, a mounting circular plate 4142 is fixedly arranged on the surface of the metal locking pin 4141, a fixing spring 4143 is connected between the front side of the mounting circular plate 4142 and the front side wall of the mounting seat 43, an arc-shaped locking plate 4144 is overlappedly arranged on the surface of the metal locking pin 4141, and the arc-shaped locking plate 4144 is fixedly installed on the L-shaped mounting column 44. The metal locking pin 4141 is pulled to drive the mounting circular plate 4142 to compress the fixing spring 4143, so that the locking of the metal locking pin 4141 on the arc-shaped locking plate 4144 can be released, and the locking The movable L-shaped mounting column 44 rotates in the mounting seat 43, and the L-shaped mounting column 44 will drive the arc-shaped locking plate 4144 to move, so that the locking hole on the left side of the arc-shaped locking plate 4144 moves to the top, and the locking hole on the top moves to the right side, and then the metal locking pin 4141 is driven by the fixing spring 4143 through the mounting circular plate 4142 to be inserted into the arc-shaped locking plate 4144, so that the position of the L-shaped mounting column 44 can be fixed, thereby fixing the position of the fine grinding disk 48 and the coarse grinding disk 411, thereby avoiding the fine grinding disk 48 or the coarse grinding disk 411 from colliding with the pull-out grinding box 3 during the grinding process.

[0046] As a preferred implementation in this embodiment, refer to Figure 8-10 The lifting component 5 includes a hydraulic push rod 51 fixedly installed on the rear side of the grinding box 1, a grinding pressure adjusting member 52 is fixedly arranged on the top of the hydraulic push rod 51, and the grinding pressure adjusting member 52 is installed at the bottom of the box cover. A limit plate 53 is arranged in front of the hydraulic push rod 51, and the limit plate 53 is fixedly installed on the rear side of the grinding box 1. A limit guide rod 54 is slidably arranged inside the limit plate 53, and the limit guide rod 54 is fixedly installed at the bottom of the box cover. The grinding pressure adjusting member 52 includes a mounting shell 521 fixedly installed on the output end of the hydraulic push rod 51, a rotating motor 522 is fixedly arranged on the right side of the mounting shell 521, and a worm 523 is fixedly arranged on the output end of the rotating motor 522, and a worm wheel 524 is meshed on the surface of the worm 523, and a rotating screw 525 is fixedly arranged inside the worm wheel 524. The rod 525 is rotatably arranged inside the mounting housing 521, and a moving column 526 is threadedly arranged on the surface of the rotating screw 525. The moving column 526 is fixedly installed at the bottom of the box cover. The hydraulic push rod 51 drives the box cover to contact the top of the grinding box 1 through the grinding pressure adjustment member 52, and guides the box cover through the limit plate 53 and the limit guide rod 54. The box cover drives the grinding component 4 to enter the grinding box 1, and drives the worm 523 to rotate forward or reversely through the output end of the rotating motor 522, so that the worm gear 524 drives the rotating screw 525 to rotate forward or reversely, so that the moving column 526 drives the box cover to move upward or downward. When the grinding force is too large, the grinding component 4 is driven to move upward through the box cover, and the grinding component 4 is driven to move downward through the box cover according to the grinding degree of the biological test material.

[0047] The working principle of the present invention is as follows: when in use, the pull-out grinding box 3 is pulled out from the grinding box 1, the biological material to be ground is placed in the pull-out grinding box 3, and the pull-out grinding box 3 with the biological material placed therein is reinserted into the grinding box 1, and the pull-out grinding box 3 is fixed by bolts. When the biological material is a plant material or muscle tissue, connective tissue and hair tissue of an animal, the fine grinding disc 48 is used to grind the biological material;

[0048] The hydraulic push rod 51 drives the box cover to contact the top of the grinding box 1 through the grinding pressure adjustment member 52, and guides the box cover through the limit plate 53 and the limit guide rod 54. The box cover drives the double-channel rotary joint 42 to move downward through the hollow shaft 41, so that the mounting seat 43 drives the cooling box 45 to move downward through the L-shaped mounting column 44, so that the cooling box 45 pushes the fine grinding disc 48 into the pull-out grinding box 3. At the same time, the L-shaped mounting column 44 drives the fixing plate 49 to enter the grinding box 1 through the fine grinding disc 48. The fixing plate 49 The coarse grinding disc 411 is driven into the grinding box 1 through the connecting column 410, and the driving motor 4131 drives the output end to drive the driving gear 4132 to rotate. The driving gear 4132 drives the hollow shaft 41 to rotate in the box cover through the driven gear 4133 meshing therewith, so that the mounting seat 43 drives the cooling box 45 to rotate through the L-shaped mounting column 44, and drives the fine grinding disc 48 to grind the biological material through the cooling box 45, and the temperature of the fine grinding disc 48 is detected by the wireless temperature sensor 415;

[0049] Especially when grinding the muscle tissue, connective tissue and hair tissue of animal materials, when the wireless temperature sensor 415 detects that the temperature of the fine grinding disc 48 is too high, the fine grinding disc 48 transmits the information to the controller 2, controls the cooling water to enter the water inlet hose 46 through the double-channel rotary joint 42, and enters the fine grinding disc 48 through the water inlet hose 46, and cools the fine grinding disc 48 by the entering cooling water, and the heat-absorbing cooling water flows back to the double-channel rotary joint 42 through the water outlet hose 47, and is discharged through the double-channel rotary joint 42. After the cooling water enters, the temperature of the fine grinding disc 48 decreases and is maintained within a reasonable range, and the biological material continues to be ground. If the temperature of the fine grinding disc 48 is still too high after the cooling water enters, the cold water of the cooling water entering is controlled to increase. If the wireless temperature sensor 415 detects that the temperature of the fine grinding disc 48 cannot be reduced, the wireless temperature sensor 415 transmits the information to the controller 2, and controls the controller 2 to control The driving motor 4131 stops grinding and continues to introduce cooling water. When the temperature of the fine grinding disk 48 decreases, the biological material can be ground again. If the temperature of the fine grinding disk 48 rises sharply during grinding again and the introduction of cooling water cannot cool it down, the controller 2 controls the rotating motor 522 to drive the output end to drive the worm 523 to rotate. The worm 523 drives the rotating screw 525 to rotate through the worm gear 524 meshing therewith, so that the moving column 526 pushes the box cover to move upward. The box cover drives the mounting seat 43 to move upward through the hollow rotating shaft 41, so that the L-shaped mounting column 44 drives the cooling box 45 to move upward, and drives the fine grinding disk 48 to move upward through the cooling box 45 to adjust the distance between the fine grinding disk 48 and the grinding material. The rotating motor 522 drives the worm 523 to reverse, so that the worm 523 drives the rotating screw 525 to reverse, so that the moving column 526 drives the box cover to move downward, and the distance between the fine grinding disk 48 and the grinding material is controlled according to the degree of grinding of the biological material.

[0050] When grinding bones of animal materials, the hydraulic push rod 51 drives the box cover to rise through the grinding pressure adjusting member 52, and the box cover drives the grinding component 4 to move out of the grinding box 1, pulls the metal locking pin 4141 to drive the mounting circular plate 4142 to compress the fixing spring 4143, rotates the L-shaped mounting column 44, so that the coarse grinding disc 411 moves to the position of the fine grinding disc 48, and the fine grinding disc 48 flips to the left, and the mounting circular plate 4142 pushes the metal locking pin 4141 to insert into the arc under the rebound action of the fixing spring 4143. Inside the L-shaped locking plate 4144, the position of the L-shaped mounting column 44 is fixed by the arc-shaped locking plate 4144, and the hydraulic push rod 51 drives the box cover to contact the top of the grinding box 1 through the double-channel rotary joint 42, so that the grinding component 4 enters the grinding box 1, so that the coarse grinding disk 411 contacts the animal bone, and the coarse grinding disk 411 compresses the pressure spring 412, and the coarse grinding disk 411 applies pressure to the animal bone through the rebound of the pressure spring 412, and the animal bone is ground by the coarse grinding disk 411.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
