An assembly space is provided in the top cover, and an annular groove is provided in the top cover. The annular groove provides a moving space for the telescopic rod to ensure that the telescopic rod can rotate in the top cover under the drive of the planetary gear. The transmission gear is provided in the top cover, the center gear is provided in the top cover, the center gear is meshed with the transmission gear, the outer ring gear is provided in the top cover, and the intermediate gear is located Below the center gear, the intermediate gear is engaged with the transmission gear, and the transmission gear drives the intermediate gear to rotate. The motor gear is engaged with the transmission gear, and the motor gear drives the transmission gear to rotate. Ball bearing 1 is arranged in the transmission gear to ensure that the transmission gear can rotate freely in the machine top cover. The thickness of ball bearing 1 is greater than the thickness of the transmission gear. Ball bearing 2 is arranged at the bottom of the intermediate gear. The planetary gear is sleeved on ball bearing 2. The planetary gear can rotate freely relying on ball bearing 2. The planetary gear is engaged with the outer ring gear. The annular bearing is arranged below the outer ring gear, and the annular bearing ensures that the outer ring gear can rotate freely in the machine top cover.

[0074] In this embodiment, the vibration assembly includes a central bearing 201, a connecting frame 202, a double-headed motor 203, a transmission rack 204, an adjustment rack 205, an adjustment knob 206, a bracket connecting rod 207, a crankshaft 208, a connecting rod 209, a crankshaft gear 210, an adjustment gear 1 211, an adjustment gear 2 212 and a mechanism housing 213. The central bearing is arranged below the central gear, and the central bearing ensures that the vibration assembly can rotate freely. The connecting frame is sleeved on the central bearing, and the double-headed motor is arranged below the connecting frame. The double-headed motor is provided with two output ends, and an assembly space is provided on the surface of the output end. The transmission racks are respectively sleeved on the double-headed motors. At the output end, the force of the double-headed motor is transmitted by the transmission rack, the adjusting rack is arranged below the double-headed motor, and the adjusting knob is arranged on one side of the transmission rack. A limiting device is provided in the adjusting knob (not shown in the figure), which can effectively prevent excessive adjustment from causing the adjusting rack to move beyond the limit and fall off. The adjusting knob is not directly connected to the crankshaft gear. At the same time, excessive movement of the adjusting rack will abut against the housing, thereby preventing it from continuing to move. The bracket connecting rod is arranged below the adjusting rack. The bracket connecting rod adopts a telescopic rod. The crankshaft is arranged below the double-headed motor. A rack is fixedly provided in the crankshaft. Connecting parts are provided at both ends of the crankshaft. The connecting rod is arranged on the crankshaft In the middle of the shaft, one end of the connecting rod is connected to the top of the bracket connecting rod, and the connecting rod drives the bracket connecting rod to vibrate up and down. The crankshaft rack is sleeved on the connecting part of the crankshaft, and the crankshaft gear is meshed with the transmission rack. The transmission rack drives the crankshaft to rotate through the crankshaft gear. The adjusting gear 1 is set at the center of the crankshaft, and the adjusting gear 1 is meshed with the adjusting rack. The adjusting gear 1 is connected to the adjusting knob. The adjusting gear 2 is set in the crankshaft, and one side of the adjusting gear 2 is meshed with the rack in the crankshaft, and the other side of the adjusting gear 2 is meshed with the adjusting rack. The adjusting gear 2 is connected to the connecting rod, and the connecting rod is driven to move by the adjusting gear 2. The adjusting gear 2 can rotate on the connecting rod. The amplitude is adjusted by adjusting the distance between the adjusting gear 2 and the center of the crankshaft. When the crankshaft rotates, the adjusting gear 2 will be driven to move synchronously. At this time, the adjusting gear 2 will move synchronously with the adjusting rack, and the adjusting rack will not move relative to the adjusting gear 2. At the same time, the adjusting gear 2 will be relatively stationary relative to the crankshaft and will not move. Since the adjusting gear 2 is not at the center of the crankshaft, the adjusting gear 2 will rotate around the center of the crankshaft driven by the crankshaft, thereby driving the connecting rod to move back and forth. The farther the distance from the center of the crankshaft, the larger the rotation radius, the longer the reciprocating distance, and the greater the amplitude of the connecting rod. Conversely, the mechanism housing is sleeved on the outside of the transmission rack, and one end of the mechanism housing is connected to the connecting frame.

[0075] In this embodiment, the supporting assembly includes a central bracket 301, a telescopic rod 302, a bracket bearing 303 and a standard screen clamp 304. The central bracket is connected to the bracket connecting rod. An assembly hole is provided on the central bracket, and the bracket connecting rod drives the central bracket to vibrate. The telescopic rod is arranged in the assembly hole of the central bracket. The top of the telescopic rod is connected to the bottom of the planetary gear, and the telescopic rod is driven to rotate by the planetary gear. The bottom of the telescopic rod is sleeved with a sleeve rod, which is arranged in the assembly hole of the central support frame. The sleeve rod can vibrate freely on the telescopic rod under the drive of the central bracket. The telescopic rod and the sleeve rod are both existing technologies and will not be repeated here. The bracket bearing is sleeved in the assembly hole of the central bracket, and the standard screen clamp is connected to the bottom of the telescopic rod. A clamping space is provided in the standard screen clamp. The standard clamp is composed of a telescopic rod. This technology is existing technology and will not be repeated here.

[0076] In this embodiment, the carrying component includes a standard sieve 4, which is arranged in a standard sieve fixture. A storage space is provided in the standard sieve, and the standard sieve is used to store the sample.

[0077] In this embodiment, the driving assembly includes a motor group 5, which is arranged below the top cover of the machine. The output end of the motor group is connected to the motor gear, and the motor group drives the motor gear to rotate.

[0078] In this embodiment, the fixing assembly includes a base 6, which is arranged below the motor unit. The motor speed adjustment knob 601 and the motor unit switch 602 are provided on the base, and the motor unit is supported by the base.

[0079] In this embodiment, the connecting assembly includes a support 7, one end of which is connected to the base, and the other end of which is connected to the top cover, so that the top cover is supported by the support.

[0080] The working principle of this utility model is:

[0081] Place a container filled with water on the base, and immerse the sample inside the standard sieve below the liquid level by adjusting the length of the telescopic rod and the bracket connecting rod. Turn on the motor unit switch and adjust the speed of the double-headed motor and the motor unit. The output end of the motor unit drives the motor gear to rotate, and the motor gear drives the transmission gear to rotate. The transmission gear drives the center gear and the intermediate gear to rotate. When the intermediate gear rotates, it drives the planetary gear and the outer gear ring to engage and rotate at the same time through the ball bearing 2. The planetary gear thereby drives the telescopic rod to rotate. When the telescopic rod rotates, it drives the standard sieve to rotate synchronously. The output end of the double-headed motor drives the transmission rack to rotate, and the transmission rack is driven by the meshing belt The dynamic crankshaft gear rotates, and the crankshaft gear rotates while driving the crankshaft to rotate. The crankshaft rotates while driving the internal adjusting gear 2 to rotate. The adjusting gear 2 drives the connecting rod to move back and forth, thereby driving the bracket connecting rod to vibrate. The bracket connecting rod thereby drives the center bracket to vibrate. The center bracket drives the sleeve rod set on the telescopic rod to vibrate. The sleeve rod drives the standard screen clamp and the standard screen to vibrate. When the amplitude needs to be adjusted, rotate the adjusting knob. The adjusting knob drives the adjusting gear 1 to rotate. The adjusting gear 1 drives the adjusting rack to move by meshing with the adjusting rack. The adjusting rack thereby drives the adjusting gear 2 to move, thereby controlling the distance between the adjusting gear and the center of the crankshaft, thereby completing the adjustment of the amplitude.
