Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of liquor brewing equipment, and in particular to a rotary digging hopper for raising and removing lees. Background Technology
[0002] In the baijiu (Chinese liquor) brewing process, grain powder is moistened, mixed with yeast powder, and then fermented in a cellar. After the required fermentation time, it is stilled to produce liquor. The remaining mash after the liquor production can be fermented and produced again multiple times in the cellar. In large-scale distilleries, mash fermentation is usually carried out in underground cellars, and the walls of these cellars are covered with a large number of various microorganisms used in fermenting the mash.
[0003] Commonly used cellars come in two shapes: cubic and cylindrical. For cylindrical cellars, the current method of using a grab bucket to remove the mash from the cellar opening is to use a grab bucket. However, the grab bucket needs sufficient space to move during opening and closing, and the movement trajectory of the grab bucket at the bottom is arc-shaped. Using a grab bucket to remove mash results in many dead corners in the cellar, making it difficult to remove mash smoothly. Workers need to enter the cellar to clean and collect the mash before removing it, resulting in low efficiency. Utility Model Content
[0004] In view of the above problems, this utility model provides a rotary opening and closing rotary digging hopper.
[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:
[0006] A rotary digging hopper is provided, including a connecting arm connected to the top of a traveling crane in the workshop, a scavenging cylinder rotatably disposed at the bottom of the connecting arm, a first driving member for driving the scavenging cylinder to rotate on the connecting arm, a bottom opening of the scavenging cylinder, a bottom cover assembly hinged to the bottom of the scavenging cylinder, and a second driving member for driving the bottom cover assembly to rotate to open / close the bottom opening of the scavenging cylinder.
[0007] The bottom cover assembly includes an upper cover and a lower cover. The upper cover is hinged to the troughing cylinder and has a trough inlet. The lower cover is coaxially rotatably disposed at the bottom of the upper cover and can close the trough inlet. The bottom cover assembly also includes a limiting component for limiting the rotation of the lower cover relative to the upper cover to the open / closed state of the trough inlet.
[0008] Furthermore, the first driving component includes a first driving motor, a driven gear is provided on the top of the troughing cylinder, and a driving gear is connected to the output end of the first driving motor, with the driving gear meshing with the driven gear.
[0009] Furthermore, the second driving component includes a second driving motor, the output end of which is coaxially connected to a winding roller, a traction rope is wound on the winding roller, one end of the traction rope is fixedly connected to the winding roller, and the other end is fixedly connected to the upper cover.
[0010] Furthermore, the lower cover is rotatably connected to the upper cover via a bearing.
[0011] Furthermore, the limiting component includes a lifting claw, which is fixedly disposed on the edge of the lower cover. The side of the lifting claw away from the lower cover is provided with a lifting inclined surface, and the upper end of the lifting claw extends beyond the lower cover and into the inlet.
[0012] Furthermore, cleaning holes are provided on the side wall of the sluice gate, and multiple cleaning holes are evenly spaced along the axial direction of the sluice gate.
[0013] Furthermore, the cleaning holes are spirally inclined on the outer wall of the sluice gate.
[0014] The beneficial effects of this utility model are as follows: When using a hopper to remove mash from the fermentation pit, a crane moves and raises the hopper within the plant area. The first drive unit drives the hopper cylinder to rotate. When the bottom cover assembly descends and contacts the mash in the fermentation pit, the resistance of the mash to the bottom cover pushes the bottom cover relative to the upper cover to rotate until the inlet is opened. As the hopper cylinder continues to descend, the mash is scooped into the hopper cylinder. After the scooping is completed, the first drive unit drives the hopper to rotate... The fermentation cylinder rotates in the opposite direction. Under the action of inertia, the lower cover rotates and resets relative to the upper cover, closing the fermentation inlet. After the trolley moves the fermentation hopper into the designated area, the second drive unit drives the bottom cover assembly to flip over and open the bottom opening of the fermentation cylinder, allowing the fermented mash to fall freely out of the fermentation cylinder. The fermentation hopper can vertically dig and remove the fermented mash in the cylindrical fermentation pit. The fermentation hopper requires little space to move during the fermentation process, which improves the effective fermentation rate of the fermentation hopper in the fermentation pit.

Detailed Implementation
[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0020] This application discloses a rotary opening and closing chute for digging and hoisting materials, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a connecting arm 1 and a sluice gate cylinder 2. The top of the connecting arm 1 is connected to a crane within the plant area, and the sluice gate cylinder 2 is connected to the bottom of the connecting arm 1. The crane can move the sluice gate cylinder 2 and the connecting arm 1 horizontally and vertically within the plant area. The top of the sluice gate cylinder 2 is provided with a connecting frame 21, which is rotatably connected to the connecting arm 1. The connecting arm 1 is provided with a first driving component for driving the sluice gate cylinder 2 to rotate. In this embodiment, the first driving component can be a first driving motor 51. A driven gear is fixedly installed on the connecting frame 21 at the top of the sluice gate cylinder 2. The first driving motor 51 is fixedly installed on the connecting arm 1 by bolts. A driving gear 53 is coaxially fixedly connected to the output shaft of the first driving motor 51. The driven gear 52 meshes with the driving gear 53. The output shaft of the first driving motor 51 can achieve forward and reverse output, thereby driving the sluice gate cylinder 2 to rotate forward and backward.
[0021] The bottom opening of the slag-raising cylinder 2 is hinged to a bottom cover assembly. A second driving component is provided on the slag-raising cylinder 2 to drive the bottom cover to rotate and open / close the bottom opening of the slag-raising cylinder 2. Specifically, the bottom cover assembly includes an upper cover 3 and a lower cover 4. The upper cover 3 is hinged to the slag-raising cylinder 2 and has a slag inlet 31. The lower cover 4 is coaxially rotatably disposed at the bottom of the upper cover 3 and can close the slag inlet 31. When the lower cover 4 closes the slag inlet 31, the lower cover 4 and the upper cover 3 can work together to close the bottom opening of the slag-raising cylinder 2.
[0022] In this embodiment, the second driving component can be a second driving motor 61, which is fixedly mounted on the connecting frame 21. A winding roller 62 is coaxially fixedly connected to the output shaft of the second driving motor 61. The winding roller 62 is rotatably mounted on the connecting frame 21, and a traction rope 63 is wound around it. One end of the traction rope 63 is fixedly connected to the winding roller 62, and the other end is fixedly connected to the upper cover 3. By driving the winding roller 62 to rotate via the second driving motor 61, the traction rope 63 can be wound and released. After releasing the traction rope 63, the bottom cover assembly can flip downwards under gravity, thereby opening the bottom opening of the fermentation cylinder 2 and allowing the fermented mash inside the fermentation cylinder 2 to be discharged.
[0023] The bottom cover assembly also includes a limiting component to restrict the rotation of the lower cover 4 relative to the upper cover 3 to the open / closed inlet 31 state. During use, the lifting cylinder 2 is driven to rotate and lowered into the pit by a trolley. After the lower cover 4 contacts the mash, it is pushed by resistance to rotate until the inlet 31 is exposed. As the lifting cylinder 2 continues to descend, it scoops the mash into the cylinder. When the lifting cylinder 2 reaches the bottom of the pit, it has completed scooping the mash below. Then, the lifting cylinder 2 is driven to rotate in the opposite direction, and the lower cover 4 stops in place due to inertia, causing it to rotate relative to the upper cover 3, blocking the inlet 31. At this point, the lifting cylinder 2 is lifted by the trolley and moved to the unloading area. By driving the bottom cover assembly to rotate relative to the fertigation cylinder 2, the bottom opening of the fertigation cylinder 2 is opened, thereby realizing the unloading of the fertigation mash.
[0024] In this embodiment, the limiting component includes a lifting claw 7, which is fixedly disposed on the edge of the lower cover 4. The upper end of the lifting claw 7 extends beyond the lower cover 4 and into the inlet 31. When the lower cover 4 rotates relative to the upper cover 3, the top of the lifting claw 7 moves within the inlet 31. When the lifting claw 7 abuts against the two sides of the inlet 31, the rotation of the lower cover 4 stops in the open / closed state of the inlet 31. A lifting ramp is provided on the side of the lifting claw 7 away from the lower cover 4. When the inlet 31 is open and the lifting cylinder 2 and the bottom cover assembly rotate to scoop out the mash, the lifting ramp design makes it easier for the material to enter the lifting cylinder 2.
[0025] In this embodiment, the lower cover 4 is rotatably connected to the upper cover 3 via a bearing, which can effectively reduce the friction between the lower cover 4 and the upper cover 3. When the trough cylinder 2 reverses to close the trough inlet 31, the lower cover 4 can rotate flexibly, ensuring that the lower cover 4 can rotate freely under inertia and close the trough inlet 31.
[0026] To facilitate the rapid cleaning of the mash adhering to the inner wall of the mash-raising cylinder 2 after unloading, in this embodiment, cleaning holes 8 are provided through the side wall of the mash-raising cylinder 2. Multiple cleaning holes 8 are evenly spaced along the axial direction of the mash-raising cylinder 2. Workers can observe the adhesion of the mash to the inner wall of the mash-raising cylinder 2 through the cleaning holes 8 and clean the mash by inserting tools into the mash-raising cylinder 2 through the cleaning holes 8. Simultaneously, the cleaning holes 8 on the side wall of the mash-raising cylinder 2 improve the air permeability of the mash inside the cylinder 2.
[0027] The cleaning holes 8 are spirally inclined on the outer wall of the slugging cylinder 2, which improves the field of vision inside the slugging cylinder 2 as seen from the cleaning holes 8, and increases the area of the inner wall of the slugging cylinder 2 that can be cleaned by workers inserting tools into the slugging cylinder 2 through one of the cleaning holes 8.
