Description

Technical Field

[0001] The utility model belongs to the field of raw material grinding, and specifically relates to a raw material grinding device for essential oil extraction. Background Art

[0002] Essential oil is a general term for volatile aromatic substances extracted from spice plants or aromatic animals. Usually, essential oils are volatile aromatic substances extracted from the flowers, leaves, roots, seeds, fruits, bark, resin, wood core and other parts of plants through steam distillation, cold pressing, fat absorption or solvent extraction. The raw materials need to be crushed and ground before extraction.

[0003] A Chinese patent with publication number CN213377013U discloses a raw material crushing device for rose essential oil extraction, comprising a crushing box; a crushing mechanism, wherein the crushing mechanism comprises a servo motor, a fixed shaft, a connecting rod, a crushing knife, a first scraper, a grinding disc, a grinding seat and a through hole, wherein a servo motor is fixedly mounted on the top surface of the crushing box through a mounting seat, a fixed shaft is fixedly sleeved on the output shaft of the servo motor, a bottom of the fixed shaft passes through the top of the crushing box and extends to the inside of the crushing box, a grinding seat is fixedly welded between the inner walls of the crushing box, a grinding disc is fixedly welded on the bottom of the fixed shaft, and a through hole matching the grinding disc is opened inside the grinding seat.

[0004] During use, the raw material crushing device for rose essential oil extraction disclosed in the application uses the inclined structure on the top of the grinding seat to allow the raw materials to slide into the through holes for crushing and grinding. However, when a large amount of raw materials are put in for grinding at one time, the speed of relying on the raw materials sliding into the through holes is slow, and the raw materials are prone to accumulate on the grinding seat and the grinding disc, thereby affecting the efficiency of grinding the essential oil raw materials.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0015] Through the cooperation of the first collecting trough, the second collecting trough and the pressure equalizing ring, it is convenient to slide a certain amount of raw material crushed into the first collecting trough and the second collecting trough, and transfer the raw material crushed from the leakage trough to the grinding disc and the inner wall of the grinding trough. At the same time, the probability of the pressure equalizing ring squeezing the raw material crushed back into the leakage trough during the downward pressure is reduced, so that the pressure equalizing ring presses down to squeeze the raw material crushed into between the grinding disc and the inner wall of the grinding trough, thereby increasing the raw material grinding rate, reducing the probability of raw material accumulation in the leakage trough, and reducing the influence of the shaft rotation on its use through the annular structure of the pressure equalizing ring.

[0027] An electric push rod 6 is installed in the shaft 401, and a connecting frame is installed at the output end of the electric push rod 6. A pressure-equalizing ring 603 located on the circumference of the shaft 401 is installed at the lower part of the connecting frame. A first collecting groove 104 is provided on the upper part of the inner wall of the grinding groove 103, and a second collecting groove 701 is provided on the upper part of the circumference of the grinding disc 7. The pressure-equalizing ring 603 is clamped in the first collecting groove 104 and the second collecting groove 701.

[0028] The application of one aspect of this embodiment is as follows: when in use, the raw material is put into the crushing trough 101, and then the motor 4 drives the shaft 401 to rotate, and the rotation of the shaft 401 drives the cutting and scraping assembly and the grinding disc 7 to rotate, the cutting and scraping assembly rotates to pre-cut and crush the raw material, and at the same time, the cutting and scraping assembly rotates to scrape the raw material attached to the inner walls of the crushing trough 101 and the leakage trough 102. At this time, the electric push rod 6 is retracted to drive the equalizing ring 603 to reciprocate and rise and fall through the connecting frame. When the equalizing ring 603 rises, the raw material fragments slide along the inner wall of the leakage trough 102 into the first aggregate trough 104 and the second aggregate trough 701. When the equalizing ring 603 falls, the equalizing ring 603 squeezes the raw material fragments in the first aggregate trough 104 and the second aggregate trough 701 into between the grinding disc 7 and the grinding trough 103, and then the rotation of the grinding disc 7 grinds the raw material fragments into powder.

[0029] The lower end of the box body 1 of this embodiment is connected to a feed pipe 105, which is communicated with the grinding tank 103. The upper end of the box body 1 is connected to a feed hopper 106, which is communicated with the crushing tank 101. A dust cover 2 is clamped on the upper part of the feed hopper 106.
