Description

Technical Field

[0001] This invention belongs to the field of jujube processing technology, and more specifically, it relates to a jujube deep processing crushing and grinding device. Background Technology

[0002] Jujubes are rich in protein, fat, carbohydrates, carotene, B vitamins, vitamin C, vitamin P, as well as calcium, phosphorus, iron and cyclic adenosine monophosphate. Crushing and grinding jujubes into powder can better utilize their nutrients and make them easier to eat and store.

[0003] The jujube crushing and grinding devices currently in use have the following problems: 1. Generally, there is only one discharge port, which requires workers to frequently change the collection bag when collecting jujube powder and jujube particles, increasing the labor intensity of workers; 2. The filter screen cannot be automatically flipped before discharging jujube particles, making it inconvenient to quickly clean the jujube particles on the filter screen; 3. There is usually a lack of intermittent collection structure, which makes it inconvenient to crush and grind jujubes of different layers, affecting the crushing and grinding efficiency of jujubes; 4. Workers need to hold the collection bag for a long time, making it impossible to position the collection bag, and jujube powder easily flows out of the collection bag, making it impossible to accurately control the collected weight of jujube powder. Summary of the Invention

[0004] This disclosure relates to a jujube deep-processing crushing and grinding device, which includes an installation unit, a screening unit, a crushing and grinding unit, an anti-rotation unit, a drive unit, a collection unit, and a discharge unit. It facilitates the crushing and grinding of jujubes at different levels, improving the crushing and grinding effect. Two rotating gears drive the screening bracket to rotate half a turn, causing the jujube particles at the top of the screening screen to automatically fall off. Jujube powder of acceptable fineness is discharged through the lower discharge bend, while jujube particles of unacceptable fineness are discharged through the upper discharge bend. When the storage weight of the collection bag is reached, the movable sealing plate automatically seals the corresponding discharge bend, preventing the jujube powder from flowing out.

Fixed connection; the connecting limit rod 503 is fixedly installed on the rear side of the two connecting drive frames 502; the drive unit 500 also includes: an arc-shaped sealing plate 504 and a flip rack 505; there are two arc-shaped sealing plates 504, and the two arc-shaped sealing plates 504 are fixedly installed on the two connecting drive frames 502, and the inner side of the two arc-shaped sealing plates 504 contacts the outer wall of the mounting housing 101; there are two flip racks 505, and the two flip racks 505 are fixedly installed on the front side of the two connecting drive frames 502; The discharge unit 700 includes: a discharge bend 701, a movable sealing plate 702, and a bag support bracket 703; the discharge bend 701 is fixedly installed on the front side of the mounting housing 101; the movable sealing plate 702 is slidably installed on the discharge bend 701; two bag support brackets 703 are provided, and the two bag support brackets 703 are fixedly installed on the movable sealing plate 702; the discharge unit 700 also includes: a circular guide rod 704, a mounting disc 705, and a return spring 706; the circular guide rod 704 is fixedly installed on the bottom of the movable sealing plate 702, and the circular guide rod 704 is also slidably connected to the discharge bend 701; the mounting disc 705 is fixedly installed on the bottom end of the circular guide rod 704; the return spring 706 is sleeved on the outside of the circular guide rod 704, and the top of the return spring 706 is connected to the fixed beam of the discharge bend 701, and the bottom of the return spring 706 is fixedly connected to the mounting disc 705; Its specific function is as follows: Since the two rotating gears 203 are fixedly installed at the left and right ends of the screening bracket 201, and the two rotating racks 505 are fixedly installed on the front side of the two connecting drive frames 502, and the two rotating racks 505 and the two rotating gears 203 are on the same plane, when the output shafts of the two linear electric cylinders 501 extend halfway, the lower end of the discharge guide bucket 102 moves between the two discharge bends 701, and the upper end of the two rotating racks 505 just contacts the two rotating gears 203; when the output shafts of the two linear electric cylinders 501 are fully extended, the lower end of the discharge guide bucket 102 moves to the upper discharge bend 701, and the two rotating gears 203 and the lower ends of the two rotating racks 505 just separate; when the two rotating racks 505 and the two rotating gears 203... When the two rotating gears 203 engage and then disengage, they drive the screening bracket 201 to rotate half a turn, causing the jujube particles at the top of the screening screen 202 to fall off automatically. Jujube powder with the correct fineness is discharged through the lower discharge bend 701, while jujube particles with the incorrect fineness are discharged through the upper discharge bend 701. Furthermore, because the connecting limit rod 503 is fixedly installed on the rear side of the two connecting drive frames 502, and the connecting limit rod 503 contacts the rear end of the movable anti-rotation rod 402, when the output shafts of the two linear electric cylinders 501 extend, the connecting limit rod 503 separates from the movable anti-rotation rod 402.

[0027] The specific usage and function of this embodiment are as follows: In use, the operator first installs the mounting housing 101 onto the workbench using bolts. Then, the output shafts of the two linear electric cylinders 501 are extended halfway. The jujubes to be crushed and ground are placed on top of the screening filter 202 through the gap between the mounting housing 101 and the sealing top cover 301. Next, the output shafts of the two linear electric cylinders 501 are fully retracted. Two collection bags are then hung on the two bag support brackets 703. The drive motor 302 is then started. When the drive motor 302 is working, the crushing and grinding blades 303 automatically crush and grind the jujubes. When the crushing and grinding blades 303 automatically crush and grind the jujubes, they push the cam 304, causing the circular force-bearing shaft 602 to move outward. The circular force-bearing shaft 602 pushes the cam... The wheel 304 and the helical spring B604 can move back and forth. When the arc-shaped movable plate 603 moves forward under the action of the pushing cam 304, some jujubes enter the rectangular storage cover 601, reducing the height of the jujubes to be crushed and ground. When the arc-shaped movable plate 603 moves backward under the action of the helical spring B604, the jujubes in the rectangular storage cover 601 are discharged, increasing the height of the jujubes to be crushed and ground, which facilitates the crushing and grinding of jujubes of different layers and improves the crushing and grinding effect. After crushing and grinding, the output shafts of the two linear electric cylinders 501 are fully extended. When the output shafts of the two linear electric cylinders 501 are half extended, the lower end of the discharge guide bucket 102 moves to the two discharge bends 701. Between, and the upper ends of the two rotating racks 505 are just in contact with the two rotating gears 203; when the output shafts of the two linear electric cylinders 501 are fully extended, the lower end of the discharge guide bucket 102 moves to the upper discharge bend 701, and the two rotating gears 203 are just separated from the lower ends of the two rotating racks 505. When the two rotating racks 505 mesh with the two rotating gears 203 and then separate, the two rotating gears 203 drive the screening bracket 201 to rotate half a turn, so that the jujube particles at the top of the screening filter screen 202 automatically fall off, and the jujube powder with qualified fineness is discharged through the lower discharge bend 701, while the jujube particles with unqualified fineness are discharged through the upper discharge bend 701; when the two linear electric cylinders 501 When the output shaft extends, the connecting limit rod 503 separates from the movable anti-rotation rod 402; when the output shafts of the two linear electric cylinders 501 are fully retracted, the connecting limit rod 503 limits the movable anti-rotation rod 402, improving the limiting effect on the screening bracket 201; when the storage weight of the collection bag is reached, the movable sealing plate 702 can automatically seal the corresponding discharge bend 701, preventing the jujube powder from flowing out and allowing the jujube powder to be temporarily stored in the discharge guide hopper 102; then the staff hangs the new collection bag on the two bag support brackets 703, and then removes the collection bag containing jujube powder. When the staff replaces the new collection bag, the movable sealing plate 702 automatically resets upward under the action of the reset spring 706.
