Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to an anti-adhesion rapid grinder. Background Art

[0002] A grinder is a device used to produce fine powder or fine granular materials by rolling and grinding large granular materials.

[0003] Existing grinders are often used before gene detection to grind different detection objects into powder or small particles for subsequent detection operations. However, the following problems exist during the grinding process:

[0004] 1. Since different detection objects have different water contents, some detection objects have more internal moisture, resulting in the extrusion of moisture during the grinding process, causing the detection materials to adhere to each other, and the detection materials adhere to the side wall of the grinding groove. At this time, the operator needs to stop the grinding operation and use a brush to sweep down the detection materials adhered to the side wall of the grinding groove. The process is cumbersome and easily causes uneven grinding of the detection materials, reducing the grinding efficiency.

[0005] 2. Since different detection materials have different effects, different detection materials need to be ground separately during grinding. Therefore, after grinding one detection material, it is necessary to clean the grinding rod and the grinding groove to sweep down the remaining powder, increasing the work intensity of the staff. Summary of the Utility Model

[0006] In order to solve the above problems, the purpose of the utility model is to provide an anti-adhesion rapid grinder, aiming to solve the problem that the detection materials adhered to the side wall of the grinding groove need to be manually swept down during the grinding process.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An anti-adhesion rapid grinder includes a base, a grinding groove rotatably arranged on the base in the front-rear direction and used for containing materials to be ground, a crushing assembly movably arranged on the grinding groove and used for crushing the materials in the grinding groove, an isolation assembly detachably arranged on the grinding groove and used for preventing the crushing assembly from directly contacting the grinding materials, a discharge port arranged at the front side of the lower part of the grinding groove, and a blocking assembly arranged on the grinding groove and used for blocking the discharge port;

[0009] The crushing assembly includes an opening and closing cover hinged on the grinding groove, a grinding rod obliquely passing through the center of the opening and closing cover and used for grinding the materials, a scraping strip rotatably arranged below the opening and closing cover and used for scraping the materials on the side wall of the grinding groove, a rotating motor arranged above the opening and closing cover, a transmission member arranged below the rotating motor and used for driving the grinding rod to rotate, and a movable rod arranged below the corresponding output shaft of the rotating motor of the transmission member and used for driving the scraping plate to rotate;

[0010] One end of the transmission part is fixedly connected to the output shaft of the rotating motor, and the other end of the transmission part is fixedly connected to the upper end of the grinding rod. The movable rod penetrates through the middle section of the grinding rod along the axis direction of the output shaft of the rotating motor and extends below the opening and closing cover. The lower end of the movable rod is fixedly connected to the scraping strip;

[0011] On both sides above the grinding groove, there are female buckles. The isolation assembly includes a fixed ring arranged above the grinding groove, an elastic isolation film arranged inside the fixed ring and used to wrap the side wall of the lower section of the grinding rod and the side wall of the scraping plate, and a pair of male buckles arranged below the fixed ring and corresponding to the female buckles on both sides respectively.

[0012] Preferably, the blocking assembly includes a blocking piece embedded in the discharge port, a pair of limiting grooves respectively arranged on the left and right sides of the discharge port, a fixing plate fixedly arranged on the front outer wall of the blocking piece, a pair of sliding tracks respectively arranged on the left and right sides of the fixing plate and arranged along the left and right length directions, a pair of limiting plates respectively slidably arranged in the two sliding tracks and in limiting connection with the limiting grooves, a force-applying plate arranged on the side of the limiting plate close to the fixing plate, and a pair of springs respectively arranged between the two force-applying plates and the fixing plate and used to push the limiting plate to slide into the limiting groove.

[0013] Preferably, an elastic sealing ring is arranged on the side wall of the blocking piece for making the side wall of the blocking piece be hermetically connected with the inner wall of the discharge port.

[0014] Preferably, a lifting plate extending out of the side wall of the grinding groove is arranged on the side wall of the fixed ring.

[0015] Preferably, a pair of limiting sliding grooves are arranged on the left and right sides of the base along the left and right length directions. Limiting rods for fixing the grinding groove are respectively arranged in the two limiting sliding grooves. A pair of limiting holes are arranged on the left and right sides of the grinding groove. The upper ends of the limiting rods are embedded in the limiting holes.

[0016] The utility model has the following beneficial effects:

[0017] 1. When the grinding rod grinds the test material in the utility model, after the grinding rod rolls over the test material, part of the test material will be pushed towards the side wall, resulting in the test material staying on the side wall of the grinding groove. The scraping plate scrapes off the test material on the side wall of the grinding groove, so that the test material falls off from the side wall and converges towards the center of the grinding groove, prompting the grinding rod to crush the test material, thus solving the problem that the test material adhered to the side wall of the grinding groove needs to be manually swept down during the grinding process;

[0018] 2. By arranging an isolation film to wrap the side wall of the lower section of the grinding rod and the side wall of the scraping plate in the utility model, the powder and particles in the grinding groove are independent of the crushing assembly. Therefore, after the grinding is completed, only the grinding groove needs to be cleaned, and a separate isolation assembly can be used for a single test material, thus reducing the cleaning process after grinding.

Detailed Description of the Embodiment

[0025] The following further describes the present utility model in detail with reference to the drawings and specific embodiments

[0026] As Figure 1 and Figure 2 shown, a non-sticking and rapid grinding machine of this embodiment includes a base 1, a grinding groove 2 rotatably arranged on the base 1 in the front-rear direction and used for containing grinding materials, a crushing component 3 movably arranged on the grinding groove 2 and used for crushing the articles in the grinding groove 2, an isolation component 4 detachably arranged on the grinding groove 2 and used for preventing the crushing component 3 from directly contacting the grinding materials, a discharge port 5 arranged at the front side of the lower part of the grinding groove 2, and a blocking component 6 arranged on the grinding groove 2 and used for blocking the discharge port 5;

[0027] The crushing component 3 includes an opening and closing cover 31 hinged to the grinding groove 2, a grinding rod 32 disposed obliquely through the center of the opening and closing cover 31 for grinding articles, a scraping strip 33 rotatably disposed below the opening and closing cover 31 for scraping the articles on the side wall of the grinding groove 2, a rotating motor 34 disposed above the opening and closing cover 31, a transmission member 35 disposed below the rotating motor 34 for driving the grinding rod 32 to rotate, and a movable rod 36 disposed below the corresponding output shaft of the rotating motor 34 of the transmission member 35 for driving the scraper to rotate;

[0028] One end of the transmission member 35 is fixedly connected to the output shaft of the rotating motor 34, the other end of the transmission member 35 is fixedly connected to the upper end of the grinding rod 32, the movable rod 36 penetrates through the middle section of the grinding rod 32 along the axis direction of the output shaft of the rotating motor 34 and extends below the opening and closing cover 31, and the lower end of the movable rod 36 is fixedly connected to the scraping strip 33;

[0029] On both sides above the grinding groove 2, there are female fasteners 7. The isolation component 4 includes a fixed ring 41 disposed above the grinding groove 2, an elastic isolation film 42 disposed inside the fixed ring 41 for wrapping the side walls of the lower section of the grinding rod 32 and the scraper, and a pair of male fasteners 43 disposed below the fixed ring 41 and corresponding to the female fasteners 7 on both sides respectively.

[0030] When the product is in use, open the opening and closing cover 31, pour the test materials to be ground into the grinding groove 2, take out a brand-new isolation component 4, align the pair of male fasteners 43 below the fixed ring 41 with the female fasteners 7 on both sides, and then press down the fixed ring 41 to fasten and fix the male fasteners 43 with the female fasteners 7. Rotate the opening and closing cover 31 downward so that the grinding rod 32 and the scraping strip 33 extend into the grinding groove 2, and the isolation film 42 is deformed by the abutment and pushing of the grinding rod 32 and the scraping strip 33, so that the isolation film 42 wraps the grinding rod 32 and the scraping strip 33. Turn on the rotating motor 34 to drive the grinding rod 32 and the scraping strip 33 to rotate, so that the grinding rod 32 crushes the materials in the grinding groove 2. The materials remaining on the side wall of the grinding groove 2 are scraped off by the scraping strip 33, and the grinding groove 2 is shaken back and forth, so that the materials in the grinding groove 2 converge towards the center of the grinding groove 2, prompting the grinding rod to crush the test materials.

[0031] As Figure 1 and Figure 3 shown, the blocking component 6 includes a blocking member 61 embedded in the discharge port 5, a pair of limiting grooves 62 respectively disposed on the left and right sides of the discharge port 5, a fixing plate 63 fixedly disposed on the front outer wall of the blocking member 61, a pair of sliding tracks 64 respectively disposed on the left and right sides of the fixing plate 63 and arranged along the left and right length directions, a pair of limiting plates 65 respectively slidably disposed in the two sliding tracks 64 and limitedly connected with the limiting grooves 62, a force-applying plate 66 disposed on the side of the limiting plate 65 close to the fixing plate 63, and a pair of springs 67 respectively disposed between the two force-applying plates 66 and the fixing plate 63 for pushing the limiting plate 65 to slide into the limiting groove 62.

[0032] When this product is in use, after grinding is completed, place a receiving box at the discharge port 5. The operator pinches the two side force plates 66 with fingers and applies a pulling force to the force plates 66 in the direction towards the fixed plate 633, causing the limiting plate 65 to disengage from the limiting groove 62, and taking out the blocking member 61. Thus, the powder in the grinding groove 2 is poured out from the discharge port 5 into the receiving box. After discharging is completed, the operator pinches the two side force plates 66 with fingers and applies a pulling force to the force plates 66 in the direction towards the fixed plate 633, causing the limiting plate 65 to contract into the sliding track 64, inserting the blocking member 61 into the discharge port 5, and releasing the hand at the alignment position of the limiting plate 65 and the limiting groove 62 to fix the position of the blocking member 61.

[0033] As Figure 2 and Figure 3 shown, an elastic sealing ring 8 for making the side wall of the blocking member 61 be hermetically connected to the inner wall of the discharge port 5 is provided on the side wall of the blocking member 61.

[0034] When this product is in use, the sealing ring 8 prevents particles from falling into the gap between the blocking member 61 and the discharge port 5, resulting in the problem of incomplete grinding.

[0035] As Figure 1 and Figure 4 shown, a lifting plate 9 extending out of the side wall of the grinding groove 2 is provided on the side wall of the fixing ring 41.

[0036] When this product is in use, when disassembling the fixing ring 41, an upward pushing force can be applied to the lifting plate 9 to prompt the sub-button 43 to separate from the mother button 7, facilitating the operator to apply force.

[0037] As Figure 1 and Figure 4 shown, a pair of limiting chutes 10 are provided on the left and right sides of the base 1 along the left and right length directions. Limiting rods 11 for fixing the grinding groove 2 are respectively provided in the two limiting chutes 10. A pair of limiting holes 12 are provided on the left and right sides of the grinding groove 2, and the upper ends of the limiting rods 11 are embedded in the limiting holes 12.

[0038] When this product is in use, when it is necessary to shake the grinding groove 2 to accelerate the grinding speed or the discharging speed, the two side limiting rods 11 are pulled in a direction away from the grinding groove 2, causing the upper ends of the limiting rods 11 to disengage from the limiting holes 12. Thus, the grinding groove 2 can be shaken back and forth at this time.

[0039] The working principle of this device is as follows:

[0040] First step: Open the opening and closing cover 31, pour the test materials to be ground, etc. into the grinding groove 2, take out a brand-new isolation component 4, align the pair of sub-buttons 43 below the fixing ring 41 with the mother buttons 7 on both sides, and then press down the fixing ring 41 to make the sub-buttons 43 and the mother buttons 7 snap and fix.

[0041] Step 2: Rotate the opening / closing cover 31 downward so that the grinding rod 32 and the scraping strip 33 extend into the grinding groove 2, causing the isolation film 42 to deform under the abutting and pushing of the grinding rod 32 and the scraping strip 33, thereby wrapping the grinding rod 32 and the scraping strip 33 with the isolation film 42. Then, turn on the rotating motor 34 to drive the grinding rod 32 and the scraping strip 33 to rotate, so that the grinding rod 32 crushes the materials in the grinding groove 2, and the materials remaining on the side wall of the grinding groove 2 are scraped off by the scraping strip 33.

[0042] Step 3: During the grinding process, the operator can slide the limiting rod 11 away from the grinding groove 2 and rock the grinding groove 2 back and forth, so as to converge the materials in the grinding groove 2 towards the center of the grinding groove 2.

[0043] Step 4: After the grinding is completed, place a receiving box at the discharge port 5. The operator pinches the two side applying plates 66 with fingers and applies a pulling force towards the fixing plate 633 to the applying plates 66, causing the limiting plate 65 to disengage from the limiting groove 62 and removing the blocking member 61, so that the powder in the grinding groove 2 is poured out through the discharge port 5 and into the receiving box.

[0044] Step 5: Rotate the grinding groove 2 forward to accelerate the pouring rate of the powder, and along with the continuous rotation of the scraping plate 34, the powder remaining on the side wall of the grinding groove 2 is scraped to the discharge port 5 and falls out, thereby accelerating the discharging rate.

[0045] Step 6: After the discharging is completed, open the opening / closing cover 31, lift the lifting plate 9 upward to prompt the sub-button 43 to disengage from the mother button 7, thereby removing the fixing ring 41 and sweeping away the small amount of powder remaining in the grinding groove 2.

[0046] Step 7: The operator pinches the two side applying plates 66 with fingers and applies a pulling force towards the fixing plate 633 to the applying plates 66, causing the limiting plate 65 to contract into the sliding track 64, inserting the blocking member 61 into the discharge port 5, and releasing the hand at the alignment position of the limiting plate 65 and the limiting groove 62 to fix the position of the blocking member 61. After supporting and aligning the grinding groove 2, slide the limiting rod 11 towards the grinding groove 2 so that the upper end of the limiting rod 11 extends into the limiting hole 12 to keep the grinding groove 2 in a vertical state.

[0047] The above is only the specific implementation manner of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
