Description

Technical Field

[0001] This invention relates to the field of edible fungi processing technology, specifically to a high-efficiency edible fungi powder grinder. Background Technology

[0002] Edible fungi refer to large, edible mushrooms (macrofungi), commonly known as mushrooms. China has more than 350 known edible fungi, most of which belong to the Basidiomycota subphylum. Common edible fungi include: shiitake mushrooms, straw mushrooms, button mushrooms, wood ear mushrooms, silver ear mushrooms, monkey head mushrooms, bamboo fungus, matsutake mushrooms, button mushrooms, red mushrooms, reishi mushrooms, cordyceps, truffles, white lingzhi mushrooms, and porcini mushrooms; a few belong to the Ascomycota subphylum, including: morels, saddle mushrooms, and truffles. The aforementioned fungi grow in different regions and ecological environments. The main effects and benefits of mushroom powder include: Antioxidant: It is rich in vitamins, which can enhance the body's antioxidant capacity and improve physical discomfort; Accelerated metabolism: Appropriate intake of mushroom powder can accelerate the body's metabolism and absorption, and improve metabolic abnormalities; Enhanced immunity: It is rich in polysaccharides, which can improve the body's immunity and disease resistance; Spleen and digestive: Mushroom powder can strengthen the spleen and aid digestion, and can improve discomfort caused by spleen and stomach weakness; Assisted in lowering blood sugar: Appropriate consumption can accelerate blood sugar metabolism and regulate blood sugar levels.

[0003] When edible fungi are ground into powder, they are usually dried first. After drying, the fungi have a hard outer shell and loose internal fibers. Therefore, when the crushing blade tears the outer shell of the fungi, the inside of the fungi will be broken into large pieces due to the tearing of the hard outer shell. Furthermore, since the density of the crushed fungi fragments is low, the crushing effect is reduced when they come into contact with the crushing blade. Therefore, a device is needed to increase the efficiency of crushing dried fungi.

[0004] Therefore, it is necessary to design a highly efficient edible mushroom powder grinder that is practical and can increase the efficiency of crushing dried mushrooms. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-6This invention provides a technical solution: a high-efficiency mushroom powder grinder, comprising a grinding barrel 1, a cover 2 placed on the upper side of the grinding barrel 1, a motor 3 fixedly connected to the lower side of the grinding barrel 1, and a drive shaft 4 connected to the output end of the motor 3 via a bevel gear transmission. The upper end of the drive shaft 4 passes through the grinding barrel 1 and extends into the interior of the grinding barrel 1. A crushing blade 5 is fixedly connected to the upper end of the drive shaft 4. An installation hole is provided in the middle of the cover 2, and a powder extraction cylinder 6 is fixedly connected to the inner wall of the installation hole. The lower side of the powder extraction cylinder 6 extends into the upper side of the interior of the grinding barrel 1. A filter screen 7 is provided on the lower inner side of the 6, a mixing mechanism 8 is provided on the middle outer side of the crushing barrel 1, and a squeezing mechanism 9 is provided on the upper side of the crushing barrel 1. An annular groove is provided on the inner wall of the powder extraction cylinder 6, a rubber ring 11 is fixedly connected to the inner wall of the annular groove, a filter screen ring 10 is fixedly connected to the inner wall of the rubber ring 11, the inner wall of the filter screen ring 10 is fixedly connected to the outer wall of the filter screen 7, a fixing hole is provided on the filter screen 7, a vibration rod 12 is fixedly connected to the inner wall of the fixing hole, and the lower end of the vibration rod 12 extends to the lower inner side of the crushing barrel 1, located on the outer side of the crushing blade 5.

[0028] When using the equipment, place the mushrooms into the inside of the grinding barrel 1, connect the upper side of the powder extraction cylinder 6 to the air extraction and filtration device, and finally start the motor 3. The motor 3 drives the drive shaft 4 and the crushing blade 5 to rotate through the bevel gear transmission. The crushing blade 5 crushes the mushrooms inside the grinding barrel 1. The crushed mushroom powder is filtered through the filter screen 7 and then extracted from the inside of the grinding barrel 1 by the powder extraction cylinder 6, thereby achieving the effect of uniformly grinding the mushrooms.

[0029] The mixing mechanism 8 includes a blower 801, a connecting assembly, and an exhaust pipe 804 on the connecting assembly. The blower 801 can supply air to the exhaust pipe 804 through the connecting assembly, and the exhaust pipe 804 can deflect vertically. The connecting assembly includes an air pipe 802. The outer wall of the blower 801 is fixedly connected to the outer wall of the grinding barrel 1. The lower end of the air pipe 802 is fixedly connected to the output end of the blower 801. The upper end of the air pipe 802 is fixedly connected to a pressure equalization chamber 803. A fixing frame 806 is fixedly connected to the outer wall of the pressure equalization chamber 803. The outer wall of the fixing frame 806 is fixedly connected to the outer wall of the grinding barrel 1. A deflection window is opened on the side wall of the grinding barrel 1. The outer wall of the exhaust pipe 804 communicates with the inner wall of the deflection window. The exhaust pipe 804 is hinged by a torsion spring and has a pressure valve inside. The output side of the pressure valve faces the inside of the crushing barrel 1. A baffle 805 is fixedly connected to the outer wall of the left end of the exhaust pipe 804. The outer wall of the baffle 805 contacts the inner wall of the pressure equalization chamber 803. The right end of the exhaust pipe 804 extends into the inside of the crushing barrel 1. A movable port is provided on the right side of the pressure equalization chamber 803. One end of the exhaust pipe 804 extends into the inside of the pressure equalization chamber 803 through the movable port. The inner wall of the pressure equalization chamber 803 has an arc-shaped structure, and the baffle 805 has an arc-shaped structure. The arc-shaped structure of the inner wall of the pressure equalization chamber 803 and the arc-shaped structure of the baffle 805 are both set with the middle part of the exhaust pipe 804 as the center.

[0030] During the process of grinding mushrooms into powder, the blower 801 is started, and the blower 801 outputs airflow into the pressure equalization chamber 803 through the air pipe 802. The airflow then blows into the grinding barrel 1 through the exhaust pipe 804, so that the crushed mushroom particles come into contact with the crushing blade 5 more quickly with the airflow, thereby speeding up the grinding efficiency.

[0031] The extrusion mechanism 9 includes a fixing component, a feed hopper 901, and a traction mechanism 905. The feed hopper 901 is located on the upper side wall of the crushing barrel 1. The outer wall of the feed hopper 901 is fixedly connected to the inner wall of the crushing barrel 1, and the feed hopper 901 connects the inside and outside of the crushing barrel 1. The fixing component also includes a rotating rod 902. The outer wall of the rotating rod 902 is rotatably connected to the inner wall of the feed hopper 901 via a bearing. One end of the rotating rod 902 extends to the outside of the feed hopper 901, and a gear is fixedly connected to the outer wall of the rotating rod 902 at the outside of the feed hopper 901. A pressure roller 903 is fixedly connected to the middle of the outer wall of the rotating rod 902. The upper side of the pressure roller 903 extends to the outside of the feed hopper 901. A sealing plate 904 is inserted into the left side of the 1. The outer wall of the sealing plate 904 contacts the inner wall of the feed hopper 901. The traction mechanism 905 includes a connecting rod 501. The outer wall of the connecting rod 501 is fixedly connected to one end of the rotating rod 902. The front end of the connecting rod 501 is fixedly connected to the rotating plate 502. The front side of the outer wall of the rotating plate 502 is fixedly connected to the rotating block 503. The outside of the rotating block 503 is rotatably connected to the pull rod 504 through the bearing. The upper part of the side wall of the crushing barrel 1 is fitted with a limiting block 505. The lower end of the pull rod 504 passes through the limiting block 505 and extends into the interior of the crushing barrel 1. The lower end of the pull rod 504 is fixedly connected to the pull rope 506. One end of the pull rope 506 is fixedly connected to the outer wall of the exhaust pipe 804.

[0032] When feeding material into the crushing barrel 1, the gear on the rotating rod 902 is rotated by the external power output device, which in turn drives the pressure roller 903 to rotate. Then, the sealing plate 904 is pulled away from the feed hopper 901, and mushrooms are fed into the feed hopper 901. When the mushrooms pass through the pressure roller 903, the rotation of the pressure roller 903 will squeeze and crush the mushrooms. The squeezed mushrooms enter the crushing barrel 1 through the lower side of the pressure roller 903. During the squeezing process, the relatively hard outer shell of the mushrooms can be broken and the internal fiber group can be broken, which makes it easier to crush and thus speeds up the crushing efficiency.

[0033] Furthermore, when the rotating rod 902 rotates, the connecting rod 501 will drive the rotating plate 502 to rotate, which in turn causes the rotating block 503 to pull the pull rod 504 to move up and down. During the movement of the pull rod 504, the pull rope 506 will be pulled, causing the exhaust pipe 804 to be pulled up and down. This allows the exhaust pipe 804 to blow air into the crushing barrel 1 repeatedly, making the mushroom particles inside the crushing barrel 1 more evenly lifted. Also, because the density of the mushrooms increases after being squeezed, they can fall faster after being knocked away by the crushing blade 5, and then be quickly brought back to the vicinity of the crushing blade by the airflow for crushing.

[0034] Furthermore, when the denser mushrooms are crushed and thrown by the crushing blade 5 onto the vibrating rod 12, the vibration of the vibrating rod 12 can shake off the larger particles attached to the filter screen 7, preventing the filter screen 7 from clogging and thus accelerating the crushing efficiency.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0036] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
