Description

Technical Field

[0001] This invention relates to the field of grinding instruments, and in particular to an automated biological sample grinding instrument. Background Technology

[0002] A grinder is a laboratory or industrial device used to crush, pulverize, and grind solid samples into finer particles. Its ultimate goal is to obtain uniform, representative, and suitable ultrafine powders for subsequent analysis or processing. Existing grinders typically have low grinding frequencies, generally 1800-3600 times / minute. They usually have a single sample tray with 1-2 perforated plates, and the sample tray vibration is generally controlled by a single axis. All perforated plates vibrate up and down simultaneously, resulting in significant machine vibration and a large size. Furthermore, the clamping cover is often manually operated, requiring manual pressure to hold all the perforated plates in place, leading to low installation efficiency and difficulty in precisely controlling the clamping force and position. In addition, the clamping cover in existing automated grinders is often a single piece, held down by a pressure bar located at the center of the back. Therefore, the pressure cannot be evenly distributed across the two sample plates, easily causing deformation of the clamping cover and potential resonance. Summary of the Invention

Under the drive of the drive mechanism, the first ends of the two drive rods rotate around the main axis of the crankshaft. The grinding assembly includes: a grinding frame and a grinding plate; The grinding frame has two grooves, and a grinding plate is slidably disposed in each of the two grooves. The two drive rods are respectively connected to the two grinding plates, and the grinding plates are used to grind biological samples.

[0004] Furthermore, the pressure cap assembly includes: an adjustment mechanism, a balance bar, and a connecting rod; The output end of the adjustment mechanism is connected to the balance bar for adjusting the height of the balance bar. Both ends of the balance bar are rotatably connected to the first end of a connecting rod, and the second end of the connecting rod is hinged to the cover plate.

[0005] Furthermore, the balance bar consists of a horizontal plate and two inclined plates. The two ends of the horizontal plate are respectively connected to one end of the two inclined plates, and the other end of the inclined plates is rotatably connected to a connecting rod. A connecting groove is provided in the middle of the horizontal plate, and the adjustment mechanism extends into the connecting groove and is rotatably connected to the horizontal plate.

[0006] Furthermore, the adjustment mechanism includes: an adjustment motor, an adjustment lead screw, and an adjustment rod; The output end of the regulating motor is connected to the regulating lead screw.

Detailed Implementation

[0013] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0014] First, combine Figures 1-3 An automated biological sample grinder according to an embodiment of the present invention is described, which is used for automatically grinding biological samples.

[0015] like Figures 1-3 As shown, an automated biological sample grinder according to an embodiment of the present invention includes: a vibration component 1, a grinding component 2, and a capping component 3; The vibration assembly 1 includes: a drive mechanism, a crankshaft 14, and a drive rod 15; The drive mechanism is used to drive the crankshaft 14 to rotate. Two drive rods 15 are connected to the crankshaft 14. The first end of the drive rod 15 is rotatably connected to the crankshaft 14. The connection points of the two drive rods 15 and the crankshaft 14 are staggered. Under the drive of the drive mechanism, the first ends of the two drive rods 15 rotate around the main shaft of the crankshaft 14. The grinding assembly 2 includes: a grinding frame 21 and a grinding plate 22; The grinding frame 21 has two sliding grooves, and a grinding plate 22 is slidably disposed in each of the two sliding grooves. The two drive rods 15 are respectively connected to the two grinding plates 22. The grinding plates 22 are used to grind biological samples. The pressure cap assembly 3 includes: a pressure cap plate 36; Each of the two grinding plates 22 is provided with a cover plate 36, which is slidably disposed in the grinding frame 21.

[0016] This application drives the crankshaft 14 to rotate via a drive mechanism. During the rotation of the crankshaft 14, two drive rods 15 rotate around the main shaft of the crankshaft 14. The drive rods 15 pull the grinding plate 22 up and down in the grinding frame 21, so that the two grinding plates 22 move alternately on the grinding frame 21. By covering the grinding plate 22 with a pressure plate 36, the biological sample is prevented from falling off the grinding plate 22 during the grinding process, thus realizing the simultaneous driving of the two grinding plates 22 to perform grinding work.

[0017] like Figures 2-3 As shown, the pressure cap assembly 3 includes: an adjustment mechanism, a balance bar 34, and a connecting rod 35; The output end of the adjustment mechanism is connected to the balance bar 34 and is used to adjust the height of the balance bar 34. Both ends of the balance bar 34 are rotatably connected to the first end of the connecting rod 35, and the second end of the connecting rod 35 is hinged to the cover plate 36.

[0018] The balance bar 34 consists of a horizontal plate and two inclined plates. The two ends of the horizontal plate are respectively connected to one end of the two inclined plates. The other end of the inclined plate is rotatably connected to the connecting rod 35. A connecting groove is provided in the middle of the horizontal plate. The adjustment mechanism extends into the connecting groove and is rotatably connected to the horizontal plate.

[0019] The adjustment mechanism includes: an adjustment motor 31, an adjustment lead screw 32, and an adjustment rod 33; The output end of the adjusting motor 31 is connected to the adjusting lead screw 32. The adjusting rod 33 is cross-shaped. The vertical rod of the adjusting rod 33 is connected to the adjusting lead screw 32. The two ends of the horizontal rod of the adjusting rod 33 are rotatably connected to the balance bar 34.

[0020] In this embodiment, by adjusting the motor 31 to drive the adjusting screw 32 to rotate, the adjusting rod 33 moves up and down on the adjusting screw 32, adjusting the height of the balance rod 34, thereby adjusting the height of the two pressure plates 36, so that the two pressure plates 36 press on the grinding plate 22. During the grinding process driven by the driving mechanism, one of the driving rods 15 pushes the grinding plate 22 to move upward, and the grinding plate 22 pushes the pressure plate 36 to move upward, so that the balance rod 34 rotates around the horizontal axis of the adjusting rod 33, so that the other pressure plate 36 moves downward, ensuring that the pressure plate 36 remains on the grinding plate 22.

[0021] like Figure 3 As shown, the grinding assembly 2 includes: a sliding plate 23 and a connecting roller 24; The sliding plate 23 is slidably disposed in the groove on the grinding frame 21, the grinding plate 22 is disposed on the sliding plate 23, a connecting roller 24 is fixed inside the sliding plate 23, and the driving rod 15 is rotatably connected to the connecting roller 24.

[0022] In this embodiment, the sliding plate 23 is connected to the drive rod 15 via the connecting roller 24, so that the drive rod 15 pulls the connecting roller 24, causing the sliding plate 23 to drive the grinding plate 22 to move up and down for grinding.

[0023] like Figures 2-3 As shown, the drive mechanism includes: a drive motor 11, a drive gear 12, a driven gear 13, and a transmission belt; The output end of the drive motor 11 is connected to the drive gear 12, the driven gear 13 is located at one end of the crankshaft 14, and the transmission belt connects the drive gear 12 and the driven gear 13.

[0024] In this embodiment, the drive motor 11 drives the drive gear 12 to rotate, and the driven gear 13 rotates synchronously with the drive gear 12 through the transmission belt, thereby causing the crankshaft 14 to rotate.

[0025] like Figure 3 As shown, the crankshaft 14 consists of a main shaft, a crank, and a crankshaft. The crank is mounted on the main shaft, and a crank shaft is provided between the two cranks. The crank shaft is offset from the main shaft. The main shaft is provided with two crank shafts, which are offset from each other. The two crank shafts are rotatably connected to two drive rods 15 respectively. When one crank shaft is at the top, the other crank shaft is at the bottom.

[0026] In this embodiment, when the main shaft rotates, the crankshaft is rotated by the crank. By setting the two crankshafts in a staggered manner, when one crankshaft moves to the top, the other crankshaft moves to the bottom, so that the two grinding plates 22 alternately rise and fall.

[0027] Above, refer to Figures 1-3 An automated biological sample grinder according to an embodiment of the present invention is described. The present application drives the crankshaft 14 to rotate via a drive mechanism. During the rotation of the crankshaft 14, two drive rods 15 rotate around the main shaft of the crankshaft 14. The drive rods 15 pull the grinding plate 22 up and down in the grinding frame 21, so that the two grinding plates 22 move alternately on the grinding frame 21. By covering the grinding plate 22 with a pressure plate 36, the biological sample is prevented from falling off the grinding plate 22 during the grinding process, thereby realizing the simultaneous driving of the two grinding plates 22 to perform grinding work.
