Description

Technical Field

[0001] The utility model belongs to the technical field of specific gravity separator equipment, in particular to a specific gravity separator capable of adjusting vibration amplitude and used for cordyceps screening. Background Art

[0002] During the planting, digging and picking process of Cordyceps, some sand and gravel particles will be mixed in. Before processing, these sand and gravel particles need to be sorted out. The processor will use a specific gravity sorter to screen the Cordyceps. The specific gravity sorter vibrates to make the sand and gravel particles and Cordyceps form effective stratification and jumping, thereby screening out the sand and gravel particles.

[0003] During use, it is necessary to adjust the frequency and amplitude of vibration according to the density and volume of Cordyceps. However, most of the specific gravity separators currently used can only adjust the frequency of vibration, but not the amplitude of vibration. Therefore, when using it, if the volume is too large or too small, the vibration amplitude is not appropriate, which will reduce the sorting accuracy and make the sand and gravel particles unable to be completely screened out. Therefore, it is necessary to design a specific gravity separator for Cordyceps screening. Utility Model Content

[0026] In order to better understand the purpose, structure and function of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] For example, see Figures 1 to 7The present embodiment discloses a specific gravity sorting machine for Cordyceps screening, comprising a base 1, a motor 2 and a sorting device 3, wherein a boss 101 is provided on the upper part of the base 1, and telescopic rods 4 are fixedly provided at the four corners of the base 1, respectively, and the top of the telescopic rod 4 is fixedly connected to the sorting device 3, and the base 1 and the sorting device 3 are connected together through the telescopic rod 4, and the boss 101 is provided with an axial hole, and the shaft of the motor 2 passes through the axial hole, and a limiting piece 201 is fixedly provided on the top of the shaft, and a threaded rod 202 is fixedly provided at the center of the limiting piece 201, and the threaded rod 202 is hinged with an annular rotating disk 5, and a plurality of threaded through holes 501 adapted to the threaded rod 202 are vertically provided on the back side of the annular rotating disk 5 along the center line, The threaded rod 202 passes through the threaded through hole 501, and the annular rotating disk 5 is fixed on the shaft rod by the nut 6, and the threaded rod 202 is adapted to the threaded through holes 501 at different positions. The distance from the center point of the threaded through hole 501 to the center point of the annular rotating disk 5 determines the swing amplitude of the annular rotating disk 5 when it rotates. A slide groove 502 is provided along the circumference of the inner wall of the annular rotating disk 5, and the slide groove 502 is adapted with a pulley 7. An L-shaped vibration rod 8 is fixedly connected at the center of the pulley 7, and the top of the L-shaped vibration rod 8 is fixedly connected to the sorting device 3. When the annular rotating disk 5 rotates, it drives the pulley 7 to make a circumferential motion in the slide groove 502, and then drives the L-shaped vibration rod 8 to move up and down, so that the sorting device 3 vibrates with a certain amplitude.

[0028] The sorting device 3 includes a vibration trough 301 and a feeding box 302, wherein the feeding box 302 is fixedly connected to the vibration trough 301, and a plurality of sieve holes 3011 are arranged in an array at the bottom of the vibration trough 301, through which the sand and gravel in the Cordyceps can be filtered out, and a sand collecting trough 102 is arranged on the top of the boss 101 for collecting the sand and gravel screened out from the sorting device 3.

[0029] A notch is provided at one end of the sand collecting trough 102, and there is a height difference at both ends of the sand collecting trough 102. The notch is located at a low position, so that the sand and gravel particles can move from the sand collecting trough 102 to the outside of the notch by gravity. A container can be placed under the notch to collect the fallen sand and gravel particles.

[0030] There is a height difference between the two ends of the vibration trough 301, and the feeding box 302 is located in the middle of the vibration trough 301. Through vibration, the high-density part and the low-density part will move in two directions, thereby classifying cordyceps with different densities.

[0031] Both ends of the vibration trough 301 are hinged with guide grooves 303 to facilitate the cordyceps to slide down from the vibration trough 301. Bolts are relatively fixed on the vertical walls on both sides of the guide groove 303. Fastening nuts 3031 are hinged on the tops of the bolts. Round through holes matching the bolts are provided on the vertical walls on both sides of the vibration trough 301. The bolts pass through the round through holes. The guide groove 303 is fixed to the vibration trough 301 through the fastening nuts 3031. The guide groove 303 is rotated by the bolts to adjust the direction of the guide groove 303 so that the cordyceps that slide down from the guide groove 303 can accurately fall into the container used to hold the cordyceps.

[0032] The telescopic rod 4 includes a sleeve 401 and a moving rod 402. The bottom of the sleeve 401 is fixedly connected to the base 1, and the top of the moving rod 402 is fixedly connected to the sorting device 3. A limit block 4021 is provided at the bottom of the moving rod 402. A spring 4022 is fixedly connected to the bottom of the limit block 4021. A limit ring 4011 adapted to the limit block 4021 is provided at the top of the sleeve 401. When the vibration amplitude of the specific gravity separator needs to be adjusted, the annular rotating disk 5 needs to be removed. At this time, the sorting device 3 loses a supporting force. The spring 4022 has a supporting effect on the moving rod 402, thereby preventing the sorting device 3 from pressing on the sand collecting trough 102 and causing damage to the equipment.

[0033] The bottom of the base 1 is provided with a plurality of rectangular straight grooves 103 , and when a forklift is used to transport the specific gravity separator, the forklift can pass through the rectangular straight grooves 103 to perform operations.

[0034] The base 1 is provided with a motor control box 104, and the motor 2 is placed on the motor control box 104, which provides a stable support for the motor 2 and enables the motor 2 to run smoothly. The motor control box 104 is provided with a start-stop button 1041 and an intensity adjustment knob 1042. The shell of the start-stop button 1041 is made of transparent material, and a red and green indicator light group is provided inside. The start-stop button 1041 and the intensity adjustment knob 1042 are surrounded by text indicators to provide a reminder to the operator.

[0035] Working principle: The threaded rod 202 is adapted to the threaded through holes 501 at different positions. The distance from the center point of the threaded through hole 501 to the center point of the annular rotating disk 5 determines the swing amplitude of the annular rotating disk 5 when it rotates. Therefore, the vibration amplitude of the specific gravity separator can be controlled within a reasonable range as needed.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
