Technical Field
[0001] The utility model relates to the technical field of grinders, in particular to a sample tissue grinder which is easy to clean. Background Art
[0002] A grinder is a device used to grind materials into powder.
[0003] Existing grinders are often used in laboratories to grind test substances and tissues for observation or experimentation. Due to the high precision requirements of the experiments, each substance needs to be ground separately, which leads to the following problems when using grinders:
[0004] 1. After the grinder is used, different samples and tissues have different uses, so different test materials need to be ground separately during grinding. Therefore, after grinding a test material, the grinding rod and the grinding groove need to be fully cleaned to sweep away the residual powder, which increases the workload of the staff.
[0005] 2. During the use of the grinder, due to the different viscosities of different substances, some substances will adhere to the outer wall of the grinding rod during the grinding process, resulting in failure to fully grind this part of the substance, resulting in uneven particle size of the product obtained after grinding. Utility Model Content
[0006] In order to solve the above problems, the purpose of the present invention is to provide a sample tissue grinder that is easy to clean, and its purpose is to solve the problem of cumbersome cleaning after grinding of existing grinders.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] A sample tissue grinder that is easy to clean comprises a base, a grinding trough rotatably mounted on the base and used to place objects to be ground, a rotating assembly disposed between the base and the bottom of the grinding trough and used to drive the grinding trough to rotate in a front-to-back direction, an opening and closing cover hingedly mounted on the grinding trough, a grinding assembly disposed on the opening and closing cover and used to grind objects in the grinding trough, and a cleaning assembly movably disposed in the grinding trough.

[0019] The utility model has the following beneficial effects:
[0020] 1. The utility model drives the output rod to move back and forth by a telescopic motor during the grinding process, prompting the rack to move back and forth along with the output rod, thereby causing the toothed member meshing with the rack to rotate back and forth along with the rack, causing the grinding trough to rotate back and forth at a uniform speed during the grinding process. During the rotation process, the sliding member slides back and forth on the corresponding sliding track under the influence of its own gravity, causing the cleaning brush on the sliding member to brush across the inner wall of the grinding trough and the outer wall of the grinding rod, thereby gathering scattered materials at the bottom of the grinding trough.

[0029] The following is a further detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments.
[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the present embodiment is a sample tissue grinder that is easy to clean, comprising a base 1, a grinding trough 2 rotatably disposed on the base 1 and used to place objects to be ground, a rotating assembly 3 disposed between the base 1 and the bottom of the grinding trough 2 and used to drive the grinding trough 2 to rotate in a front-to-back direction, an opening and closing cover 4 hingedly disposed on the grinding trough 2, a grinding assembly 5 disposed on the opening and closing cover 4 and used to grind objects in the grinding trough 2, and a cleaning assembly 6 movably disposed in the grinding trough 2;
[0031] Rotating columns 7 are respectively provided on the left and right sides of the grinding tank 2, and a support column 8 is fixed on the end of each rotating column 7 away from the grinding tank 2, and the lower end of each support column 8 is fixedly connected to the base 1;
[0032] The grinding assembly 5 includes a through hole 51 provided in the center of the opening and closing cover 4, a grinding rod 52 rotatable along the circumferential direction and obliquely passing through the through hole 51, a rotating motor 53 fixed to the opening and closing cover 4, and a transmission plate 54 fixed to the output end of the rotating motor 53;
[0033] The upper end of the grinding rod 52 is fixedly connected to the end of the transmission plate 54 away from the output shaft of the rotating motor 53;
[0034] The cleaning assembly 6 includes a pair of sliding rails 61 disposed on the left and right sides of the grinding tank 2 and arranged horizontally in the front-to-back direction, a pair of sliding sleeves 62 movably mounted on the sliding rails 61 on both sides, a pair of cleaning brushes 63 detachably mounted on the side walls of the sliding sleeves 62, and a plurality of rollers 64 rotatably mounted on the inner walls of the sliding sleeves 62 and abutting against the outer walls of the sliding rails 61.
[0035] The rotating assembly 3 includes a toothed part 31 fixed to the outer wall of the grinding tank 2 in the front-to-back direction, a telescopic motor 32 fixed to the base 1 and movable and retractable in the front-to-back direction, and a rack 33 provided on the output rod of the telescopic motor 32 and meshing with the toothed part 31.
[0036] When the product is in use, the opening and closing cover 4 is opened, the material to be ground is placed in the grinding tank 2, and then the opening and closing cover 4 is closed, and the rotating motor 53 is turned on to cause the output shaft of the rotating motor 53 to rotate circumferentially, thereby driving the transmission plate 54 to rotate axially along the axis of the output shaft, thereby driving the grinding rod 52 to rotate, crushing the material at the bottom of the grinding tank 2, and turning on the telescopic motor 32 to drive the output shaft of the telescopic motor 32 to slide back and forth, thereby causing the rack 33 to move back and forth, causing the toothed member 31 meshing with the rack 33 to move back and forth with the movement of the rack 33, thereby driving the grinding tank 2 to rotate back and forth. In the process of the grinding tank 2 rotating back and forth, the sliding sleeves 62 on the sliding rails 61 on both sides slide in the inclined direction under the action of their own gravity, thereby causing the sliding sleeves 62 on both sides to slide They slide back and forth along their respective sliding rails 61, so that the sliding sleeve 62 drives the cleaning brush 63 to slide back and forth in the grinding tank 2, so that the cleaning brush 63 brushes over the inner wall of the grinding tank 2 and the outer wall of the grinding rod 52, and sweeps off the adhering materials on the inner wall of the grinding tank 2 and the outer wall of the grinding rod 52, preventing the materials from adhering to the inner wall of the grinding tank 2 or the outer wall of the grinding rod 52, and in the sliding process of the sliding sleeve 62, the conical sleeve 11 brushes over the surface of the corresponding sliding rail 61, thereby scraping the material powder on the sliding rail 61 to the bottom of the grinding tank 2, so that after grinding, no large amount of material powder will remain on the inner wall of the grinding tank 2, and at the same time, the material on the grinding rod 52 is also swept into the grinding tank 2, thereby greatly reducing the difficulty of cleaning the grinder for the operator.
[0037] like Figure 5 As shown, a barbed surface 621 is fixedly provided on the side wall of the sliding sleeve 62 , and a hairy surface 631 adhered to the barbed surface 621 is fixedly provided on the connection side of the cleaning brush 63 and the side wall of the sliding sleeve 62 , and the hairy surface 631 completely wraps the barbed surface 621 .
[0038] When this product is in use, after grinding is completed, the operator controls the telescopic motor 32 to slide backward, causing the rack 33 to drive the toothed member 31 to move backward, causing the front of the grinding tank 2 to tilt downward, so that the material in the grinding tank 2 is gathered at the bottom of the front part of the grinding tank 2. At this time, the operator opens the opening and closing cover 4 and tears off the hair surface 631 of the cleaning brushes 63 on both sides, so that the two cleaning brushes 63 can be used to carefully clean the grinding tank 2 and collect the grinding material.
[0039] like Figure 3 and Figure 5 As shown, a side wall of the sliding sleeve 62 is provided with an alignment groove 9 , and a side where the rough surface 631 and the burr surface 621 are adhered is fixed with an alignment piece 10 embedded in the alignment groove 9 .
[0040] When this product is in use, after grinding and collecting one substance, when a new substance needs to be ground, in order to prevent the residual powder of the substance in the cleaning brush 63 from affecting the purity result of the grinding of the new substance, the two cleaning brushes 63 can be replaced or cleaned separately, and then the alignment pieces 10 on the bristle surfaces 631 of the clean pair of cleaning brushes 63 are aligned with the alignment grooves 9 on the corresponding sliding sleeves 62, and then the cleaning brushes 63 are pushed inward, and the bristle surface 631 is adhered to the thorn surface 621 by pressing, thereby completing the replacement, and ensuring that the position of the bristle surface 631 is aligned to completely cover the position of the thorn surface 621, thereby preventing powder from entering the thorn surface 621 during the grinding process and remaining on the thorn surface 621.
[0041] like Figure 5 As shown, two conical sleeves 11 for scraping powder off the surface of the sliding track 61 are fixedly provided at the front and rear ends of the two sliding sleeves 62 .
[0042] When this product is in use, the material is crushed and rotates back and forth in the grinding groove 2, which inevitably causes it to be stirred up, causing some powder to fall onto the sliding track 61. When the sliding sleeves 62 slide back and forth along their respective sliding tracks 61, the narrow end of the conical sleeve 11 slides against the surface of the sliding track 61, thereby sweeping the material powder on the sliding track 61 off.
[0043] like Figure 2 and Figure 4 As shown, an elastic sealing member 12 is fixedly provided in the through hole 51 , and the elastic sealing member 12 is sealedly connected to the outer wall of the grinding rod 52 .
[0044] When this product is in use, since the ground material is mostly in powder form, and during the back and forth rotation of the grinding tank 2, the powder material in the grinding tank 2 is stirred up and scattered in the grinding tank 2, the setting of the elastic seal 12 prevents the problem of powder floating out of the through hole 51.
[0045] like Figure 1 As shown, a switch door 13 is hingedly provided on the front side wall of the grinding tank 2 corresponding to the lower side of the sliding track 61.
[0046] When this product is in use, after grinding is completed, the operator controls the telescopic motor 32 to slide backward, causing the rack 33 to drive the toothed part 31 to move backward, causing the front of the grinding tank 2 to tilt downward, so that the material in the grinding tank 2 is gathered at the bottom of the front part of the grinding tank 2. At this time, the operator opens the opening and closing cover 4, and tears off the hairy surface 631 of the cleaning brush 63 on both sides, then opens the switch door 13, and uses the cleaning brush 63 to sweep the material in the grinding tank 2 out of the switch door 13 for collection, thereby achieving the effect of gathering the ground material and facilitating the operator to collect it.
[0047] The working principle of this device is:
[0048] The first step: open the opening and closing cover 4, put the material to be ground into the grinding tank 2, then close the opening and closing cover 4, and turn on the rotating motor 53, so that the output shaft of the rotating motor 53 rotates circumferentially, thereby driving the transmission plate 54 to rotate axially along the axis of the output shaft, thereby driving the grinding rod 52 to rotate, crushing the material at the bottom of the grinding tank 2.
[0049] Step 2: Turn on the telescopic motor 32 to drive the output shaft of the telescopic motor 32 to slide back and forth, thereby making the rack 33 move back and forth, causing the toothed member 31 meshing with the rack 33 to move back and forth along with the movement of the rack 33, thereby driving the grinding tank 2 to rotate back and forth.
[0050] Step 3: During the back and forth rotation of the grinding tank 2, the sliding sleeves 62 on the sliding rails 61 on both sides slide in the inclined direction under the action of their own gravity, so that the sliding sleeves 62 on both sides slide back and forth along the paths of their respective sliding rails 61, so that the sliding sleeves 62 drive the cleaning brush 63 to slide back and forth in the grinding tank 2, so that the cleaning brush 63 brushes over the inner wall of the grinding tank 2 and the outer wall of the grinding rod 52, sweeping off the adhered materials on the inner wall of the grinding tank 2 and the outer wall of the grinding rod 52, and preventing the materials from adhering to the inner wall of the grinding tank 2 or the outer wall of the grinding rod 52, and during the sliding process of the sliding sleeve 62, the conical sleeve 11 brushes over the surface of the corresponding sliding rail 61, thereby scraping the material powder on the sliding rail 61 to the bottom of the grinding tank 2.
[0051] Step 4: After the grinding is completed, the operator controls the telescopic motor 32 to slide backward, causing the rack 33 to drive the toothed part 31 to move backward, causing the front of the grinding tank 2 to tilt downward, so that the material in the grinding tank 2 is gathered at the bottom of the front part of the grinding tank 2. At this time, the operator opens the opening and closing cover 4, and tears off the hairy surface 631 of the cleaning brush 63 on both sides, then opens the switch door 13, and uses the cleaning brush 63 to sweep the material in the grinding tank 2 out of the switch door 13 for collection.
[0052] Step 5: Take out the removed cleaning brush 63 and clean it separately or replace it with a new pair of cleaning brushes 63, and align the alignment parts 10 of the new cleaning brush 63 with the corresponding alignment grooves 9 and insert them into the alignment grooves 9, and then press and adhere their respective hair surfaces 631 and thorn surfaces 621, so that each grinding material uses its own separate cleaning brush 63, preventing the residual material on the cleaning brush 63 from mixing with the new material, resulting in impure ground powder.
[0053] The above description is only a specific embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
