In the technical solution, the annular disc moves up and down in the screening barrel along the trajectory of the annular wave groove while rotating with the connecting rod. The food raw materials that are not completely crushed cannot be screened out in the screening barrel, and the secondary crushing mechanism below the annular disc is used to mill the food raw materials that are not completely crushed and cannot be screened.

[0004] The above-mentioned patent still has the following defects:

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0035] Please refer to Figure 1 - Figure 4The embodiment provides a kind of cordyceps supermicro pulverization screening equipment, including collection bucket 1, collection bucket 1 bottom is equipped with discharge port, and discharge pipe is installed in the discharge port at the bottom of collection bucket 1 for centralized collection work.In the upper portion of collection bucket 1, a first crushing mechanism 2 is provided, and an open feed bin 3 is provided above the first crushing mechanism 2.A sealing feeding mechanism 4 is installed between the collection bucket 1 and the first crushing mechanism 2 and between the open feed bin 3 and the first crushing mechanism 2.The sealing feeding mechanism 4 includes a connecting cylinder 41, a connecting shaft 42 is rotatably connected in the connecting cylinder 41, a plurality of sealing plates 43 are annularly arrayed on the outer periphery of the connecting shaft 42 and abut against the inner wall of the connecting cylinder 41.A first motor 44 is installed on the side of the connecting cylinder 41 to drive the rotation of the connecting shaft 42.Two sealing feeding mechanisms 4 can share one first motor 44 to reduce the use of driving equipment and the cost investment.

[0036] Further, referring to Figure 3 、 Figure 5 and Figure 8 , a screen barrel 5 is coaxially rotatably connected in the collection bucket 1.It is necessary to note that the screen barrel 5 needs to be directly communicated with the sealing feeding mechanism 4 below the first crushing mechanism 2.A plurality of screen holes 51 are provided on the side and bottom of the screen barrel 5.A second crushing mechanism 6 is installed at the bottom of the collection bucket 1.The second crushing mechanism 6 includes a rotating shaft 61 coaxially rotatably connected with the collection bucket 1 and the screen barrel 5 and a plurality of crushing knives 62 uniformly fixed on the rotating shaft 61.A driving device 8 is installed at the bottom of the collection bucket 1 to drive the rotation of the screen barrel 5 and the rotating shaft 61.The driving device 8 drives the high-speed rotation of the crushing knives 62 to further crush the cordyceps in the screen barrel 5, and simultaneously drives the rotation of the screen barrel 5.

[0037] Further, referring to Figure 5 - Figure 7 , the device further includes an anti-blocking mechanism 7.The anti-blocking mechanism 7 includes an L-shaped plate 71 fixed in the collection bucket 1 and located outside the screen barrel 5.A column of spring barrels 72 corresponding to the screen holes 51 are fixed on the L-shaped plate 71.A thimble 73 is slidably connected in the spring barrel 72 and abuts against the screen barrel 5.A compression spring 74 is installed between the thimble 73 and the spring barrel 72.

[0038] Further, the use scenario is introduced as follows.When the cordyceps is crushed and screened, the first motor 44, the driving device 8 and the first crushing mechanism 2 are started, and then the dried cordyceps is poured into the open feed bin 3.After passing through the sealing feeding mechanism 4 above the first crushing mechanism 2, the cordyceps is sent to the first crushing mechanism 2 for the first crushing.The crushed cordyceps falls into the sealing feeding mechanism 4 below the first crushing mechanism 2, and then is orderly transported into the screen barrel 5 through the sealing feeding mechanism 4.

[0039] Then, the driving device 8 drives the rotating shaft 61 to rotate at high speed, and the screen barrel 5 also rotates coaxially. The high-speed rotation of the rotating shaft 61 drives the crushing knife 62 to cut the cordyceps at high speed, and then the cordyceps is secondarily crushed. If the size of the crushed cordyceps is smaller than the size of the screen hole 51, the cordyceps will fall into the collecting barrel 1 through the screen hole 51. Further, there are also cordyceps with similar sizes of the screen hole 51 that will be blocked in the screen hole 51. If the screen hole 51 is not processed in time, it will affect the screening of the cordyceps and reduce the crushing and screening efficiency of the cordyceps. The embodiment of the application drives the screen barrel 5 to rotate through the driving device 8, so that each column of screen holes 51 on the screen barrel 5 passes through the anti-blocking mechanism 7. When the blocked screen hole 51 passes through the anti-blocking mechanism 7, the jammed cordyceps in the screen hole 51 will be quickly pushed into the screen barrel 5 by the ejector pin 73 under the action of the compression spring 74, so that the function of dredging the blocked screen hole 51 is completed. Moreover, since the screen barrel 5 is always rotating, when a certain screen hole 51 is blocked and rotates to the anti-blocking mechanism 7, it will be dredged. In this way, the cordyceps with a size close to the size of the screen hole 51 can smoothly fall into the collecting barrel 1, and the crushing and screening efficiency of the cordyceps is improved.

[0040] In addition, when the cordyceps is crushed, because the rotating shaft 61 drives the crushing knife 62 to rotate at high speed, the cordyceps powder is lifted. Because the sealing feeding mechanism 4 is arranged between the first-stage crushing mechanism 2 and the open feeding bin 3 and between the first-stage crushing mechanism 2 and the collecting barrel 1, the lifted cordyceps powder cannot escape to the feeding bin and then escape to the outside to cause waste. The sealing and feeding process of the sealing feeding mechanism 4 is as follows: when the cordyceps is poured into the open feeding bin 3, the connecting shaft 42 is driven to rotate with the rotation of the first motor 44. Because the sealing plates 43 on the connecting shaft 42 are arranged in an annular array, and the side surface of the sealing plate 43 and the side away from the connecting shaft 42 are in contact with the connecting cylinder 41, when the included angle area between the two sealing plates 43 is located below the open feeding bin 3, the cordyceps in the open feeding bin 3 falls into the included angle area surrounded by the two sealing plates 43. With the continuous rotation of the connecting shaft 42, the cordyceps is brought to the first-stage crushing mechanism for crushing, so that the feeding function is realized. Similarly, the crushed cordyceps by the first-stage crushing mechanism 2 is sent to the screen barrel 5 in the collecting barrel 1 by the sealing feeding mechanism 4 below the first-stage crushing mechanism 2 for secondary crushing. Because the side surface of the sealing plate 43 and the side away from the connecting shaft 42 are in contact with the connecting cylinder 41, the adjacent two sealing plates 43 and the connecting cylinder 41 form a relatively closed space, so that the lifted cordyceps powder cannot easily escape to the outside to cause waste. Because the sealing feeding mechanism 4 is arranged above and below the first-stage crushing mechanism 2, the cordyceps powder cannot escape, the collection effect of the cordyceps is improved, and waste caused by escape to the outside is avoided.

[0041] Further, referring to Figure 4 The sealing plate 43 comprises a feeding plate one 431 fixed to the connecting shaft 42, and the side away from the connecting shaft 42 of the feeding plate one 431 is provided with an adjusting groove 432. A feeding plate two 433 in contact with the inner wall of the connecting cylinder 41 is slidably connected in the adjusting groove 432. The feeding plate two 433 is T-shaped. The two sides of the feeding plate one 431 are in contact with the connecting cylinder 41, and the two sides and the side away from the feeding plate one 431 of the feeding plate two 433 are in contact with the connecting cylinder 41. A plurality of compression springs two 434 are arranged in the adjusting groove 432. One end of the compression spring two 434 is fixed to the feeding plate two 433, and the other end is fixed to the adjusting groove 432.

[0042] In combination with a specific use scene, the plurality of compression springs 434 is used to tightly abut the feeding plate 433 against the inner wall of the connecting cylinder 41, and the two sides of the feeding plate 431, the two sides of the feeding plate 433 and the side of the feeding plate 433 away from the feeding plate 431 are in contact with the connecting cylinder 41, so that the overall sealing performance of the sealing feeding mechanism 4 is further improved, the powder is not easy to escape from the sealing feeding mechanism 4, and the collection efficiency of the cordyceps sinensis powder is improved.

[0043] Further, the end of the feeding plate 433 away from the feeding plate 431 is V-shaped, so that the abutting area of the side of the feeding plate 433 away from the feeding plate 431 and the connecting cylinder 41 is reduced, and the friction therebetween is reduced, so that the sealing plate 43 rotates smoothly.

[0044] The sealing feeding mechanism 4 is installed between the primary damage mechanism and the collection barrel 1 and between the primary damage mechanism and the open feeding bin 3, so that the cordyceps sinensis powder that is lifted is prevented from escaping to the outside and causing waste. The anti-blocking mechanism 7 is installed in the collection barrel 1, and when the screen barrel 5 is driven to rotate by the driving device 8, each column of screen holes 51 on the screen barrel 5 will pass through the anti-blocking mechanism 7 in turn, and the screen holes 51 that are blocked are dredged by the push pin 73 under the elastic force of the compression spring 74, so that the screening efficiency of the cordyceps sinensis is ensured. Overall, not only can the feeding be continued, but also the powder escaping from the feeding port can be reduced, the screen hole 51 can be prevented from being blocked, and the efficiency of the cordyceps sinensis crushing and screening is improved.

[0045] Referring to Figure 3 and Figure 8 As a specific embodiment of the present application, the driving device 8 comprises a second motor 81 installed at the bottom of the collection barrel 1, the second motor 81 is in transmission connection with the rotating shaft 61 through a shaft coupling 85, the screen barrel 5 is fixedly connected with a gear ring 82 at the bottom, the screen barrel 5 is rotatably connected with a transmission gear 83 in meshing connection with the gear ring 82, and the rotating shaft 61 is fixedly connected with a driving gear 84 in meshing connection with the transmission gear 83.

[0046] In combination with a specific use scenario, the second motor 81 is started to drive the secondary crushing mechanism to rotate at a high speed, and the highly rotating crushing knife 62 is used to crush the cordyceps sinensis again. When the rotating shaft 61 rotates, the second motor 81 drives the driving gear 84 to rotate synchronously. Since the driving gear 84, the transmission gear 83 and the transmission gear 83 and the gear ring 82 are all in meshing connection, the second motor 81 will also drive the screen barrel 5 fixedly connected with the gear ring 82 to rotate, so that the screen holes 51 on the screen barrel 5 pass through the anti-blocking mechanism 7 in turn and are dredged by the thimbles 73 of the anti-blocking mechanism 7. The transmission gear 83 is used to make the rotating directions of the rotating shaft 61 and the screen barrel 5 opposite, so that the screen barrel 5 can crush the cordyceps sinensis with the crushing knife 62 more efficiently, thereby improving the crushing efficiency of the cordyceps sinensis.

[0047] With reference to Figure 3 , Figure 5 and Figure 8 , as a specific embodiment of the present application, a circular annular bearing seat 9 is fixedly connected to the inner bottom wall of the collecting barrel 1, a double-row deep groove ball bearing 93 is installed in the inner hole of the bearing seat 9, and the rotating shaft 61 is fixedly connected to the inner ring of the double-row deep groove ball bearing 93. An annular groove 91 is formed in the top of the bearing seat 9, and a plurality of rolling bodies 92 are installed in the annular groove 91. The rolling bodies 92 abut against the bottom of the screen barrel 5.

[0048] In combination with a specific use scenario, the annular groove 91 and the plurality of rolling bodies 92 installed in the annular groove 91 will not affect the rotation of the screen barrel 5, but can also improve the support strength of the screen barrel 5, thereby ensuring the installation stability of the screen barrel 5.

[0050] In combination with a specific use scenario, the installation groove 95 is formed in the bearing seat 9 to provide installation space for the gear ring 82, the driving gear 84 and the transmission gear 83. The cooperation of the dustproof plate 96 and the dustproof groove 52 can prevent the cordyceps sinensis powder from entering the installation groove 95, thereby affecting the meshing of the gear ring 82, the transmission gear 83 and the driving gear 84 in the installation groove 95, ensuring the stability of the rotation of the screen barrel 5, and further ensuring the smoothness and stability of the dredging of the screen holes 51.

[0052] In combination with a specific use scenario, when the screen barrel 5 rotates, the material collecting plate 10 is driven to rotate, and then the first cleaning brush 101 is used to clean and collect the cordyceps sinensis powder at the bottom of the collecting barrel 1, so that the cordyceps sinensis powder is gradually collected to the material collecting opening at the bottom of the collecting barrel 1, and then enters the material collecting pipe 15, thereby ensuring the smoothness and stability of the collection of the cordyceps sinensis powder.

[0053] Referring to Figure 3 and Figure 6 , as a specific embodiment of the present application, a sidewall cleaning piece 11 is fixedly connected to the side of the material collecting plate 10 close to the collecting barrel 1, the sidewall cleaning piece 11 includes a connecting plate 111 and a second cleaning brush 112, and the bristles of the second cleaning brush 112 abut against the sidewall of the collecting barrel 1.

[0054] In combination with a specific use scenario, by installing the sidewall cleaning piece 11 on the side of the material collecting plate 10, when the screen barrel 5 rotates, the sidewall cleaning piece 11 is driven to rotate, and then the second cleaning brush 112 is driven to clean the sidewall of the collecting barrel 1, so that the dust deposited on the sidewall of the collecting barrel 1 is cleaned and falls into the bottom of the collecting barrel 1, thereby ensuring the collection effect of the cordyceps sinensis powder.

[0055] Further referring to Figure 6 , a ring-shaped top support plate 131 is fixedly connected to the top of the collecting barrel 1, an auxiliary support plate 132 is fixedly connected to the side of the top support plate 131, a horizontal sliding groove 1111 is formed in the top of the connecting plate 111, and the auxiliary support plate 132 is located in the horizontal sliding groove 1111, so that the auxiliary support plate 132 supports the connecting plate 111 in the vertical direction under the condition that the connecting plate 111 normally rotates, thereby ensuring the overall installation stability of the connecting plate 111 and the material collecting plate 10, and further ensuring the stability of the cleaning and collection of the cordyceps sinensis powder on the sidewall and the bottom of the collecting barrel 1.

[0058] With reference to Figure 8 As a specific embodiment of the present application, the screen hole 51 gradually decreases in diameter from the outer wall side of the screen barrel 5 to the inner wall side of the screen barrel 5, the tip of the thimble 73 matches the shape of the screen hole 51, and the side corner of the thimble 73 close to the screen barrel 5 is rounded.
