Description

Technical Field

[0001] This utility model relates to the field of liquor production technology, and in particular to a grab bucket for lifting liquor in liquor production. Background Technology

[0002] The Maotai-flavor type, also known as the Maotai aroma type, is represented by Maotai, a renowned liquor both domestically and internationally, and belongs to the Daqu (large-grain) liquor category. It is characterized by its prominent, elegant, and delicate Maotai aroma, mellow body, long finish, clear and transparent appearance, and slightly yellow color.

[0003] Distilleries generate a large amount of lees during the production of Maotai-flavor liquor, requiring the use of grab buckets for lees transfer. Existing grab buckets simply open to allow the material to fall naturally under gravity. However, because the lees are moist and have adhesive properties, they easily adhere to the inner wall of the grab bucket, preventing complete discharge during gravity-based lees removal and affecting subsequent use. Therefore, there is an urgent need to develop a baijiu production grab bucket that facilitates material handling and discharge, and uses vibration-assisted discharge to ensure the complete removal of adhesive materials, thus overcoming the shortcomings of current applications and meeting current needs. Utility Model Content

[0004] The purpose of this utility model is to provide a grab bucket for opening cellars in the production of baijiu (Chinese liquor) to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grab bucket for opening a fermentation pit in baijiu (Chinese liquor) production includes a frame, grab buckets, hydraulic telescopic components, an auxiliary unloading mechanism, and support shafts. There are two grab buckets and two support shafts. Each grab bucket has two fixed collars. The support shafts are fixed inside the frame. The two grab buckets are rotatably connected to the two support shafts via collars. Two hydraulic telescopic components for swinging the two grab buckets are installed inside the frame. An auxiliary unloading mechanism for vibrating and unloading the two grab buckets is also installed inside the frame. The auxiliary unloading mechanism includes a swing arm, a striking cylinder, a rotating shaft, a motor, an eccentric cam, and a spring. The upper end of the swing arm is fixed to the rotating shaft, which is rotatably connected inside the frame. The lower end of the swing arm is fixed to the striking cylinder. The upper end of the spring is fixed to the frame, and the lower end is fixed to the swing arm. The motor is fixed inside the frame, and an eccentric cam is fixed to the output shaft of the motor, with the eccentric cam in contact with the swing arm.

[0007] Preferably, the two hydraulic telescopic components are arranged symmetrically on the left and right.

[0008] Preferably, the lower end of the hydraulic telescopic assembly is fixed with a first pin, which is rotatably connected to the grab hopper, and the upper end of the hydraulic telescopic assembly is fixed with a second pin, which is rotatably connected to the frame.

[0009] Preferably, two lifting rings are fixed on the frame.

[0010] Preferably, the two gripping hoppers are arranged with their opening ends facing each other.

[0011] Preferably, the striking cylinder is made of stainless steel.

[0012] The beneficial effects of this utility model are as follows: When using a grab bucket for liquor production, during material collection, a hydraulic telescopic assembly pushes the grab bucket downwards, causing it to rotate around a support shaft. This brings the two grab buckets closer together, thus grabbing the lees. During material discharge, the hydraulic telescopic assembly pulls the grab buckets upwards, separating them and allowing the lees to drain. Once the grab buckets are fully open, a motor drives an eccentric cam to rotate. This cam rotation, in turn, causes a swing arm to swing up and down, which in turn causes a striking cylinder to swing up and down. The striking cylinder then vibrates the grab buckets, causing the lees adhering to the inner wall of the grab buckets to detach and be discharged, ensuring more thorough material discharge. In summary, this utility model offers convenient material collection and discharge, and the vibration-assisted discharge method ensures the complete removal of adhering materials.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figure 1-4 The present invention relates to a grab bucket for opening a fermentation pit in baijiu production, comprising a frame 1, grab buckets 3, hydraulic telescopic components 4, an auxiliary unloading mechanism 5, and a support shaft 6. There are two grab buckets 3 and two support shafts 6. The open ends of the two grab buckets 3 are arranged opposite each other. Each grab bucket 3 has two collars 301 fixed on it. The support shaft 6 is fixed inside the frame 1. The two grab buckets 3 are rotatably connected to the two support shafts 6 via collars 301. Two hydraulic telescopic components 4 are installed inside the frame 1 to drive the two grab buckets 3 to swing. The two hydraulic telescopic components 4 are symmetrically arranged left and right. A mechanism for vibrating and unloading the two grab buckets 3 is also installed inside the frame 1. The auxiliary unloading mechanism 5 includes: a rocker arm 501, a striking cylinder 502, a rotating shaft 503, a motor 504, an eccentric cam 505, and a spring 506. The upper end of the rocker arm 501 is fixed to the rotating shaft 503, which is rotatably connected to the frame 1. The lower end of the rocker arm 501 is fixed to the striking cylinder 502. The upper end of the spring 506 is fixed to the frame 1, and the lower end is fixed to the rocker arm 501. The motor 504 is fixed inside the frame 1, and the output shaft of the motor 504 is fixed to the eccentric cam 505, which is in contact with the rocker arm 501. The striking cylinder 502 is made of stainless steel.

[0021] The lower end of the hydraulic telescopic assembly 4 is fixed with a first pin 401, which is rotatably connected to the grab hopper 3. The upper end of the hydraulic telescopic assembly 4 is fixed with a second pin 402, which is rotatably connected to the frame 1.

[0022] Two lifting rings 2 are fixed on the frame 1, and the steel cable of the external lifting mechanism is connected to the lifting rings 2 so that the external lifting mechanism can drive the frame 1 to move up and down.

[0023] Working principle: This baijiu production uses a grab bucket for opening the cellar. When picking up materials, the hydraulic telescopic component 4 pushes the grab bucket 3 downward, causing the grab bucket 3 to rotate around the support shaft 6, so that the two grab buckets 3 come closer together and grab the lees. When discharging materials, the hydraulic telescopic component 4 pulls the grab bucket 3 upward, causing the grab buckets 3 to separate, so that the lees in the two grab buckets 3 can be discharged. When the grab bucket 3 is in the open position, the motor 504 drives the eccentric cam 505 to rotate. The rotation of the eccentric cam 505 drives the swing arm 501 to swing up and down. The swing arm 501 drives the striking cylinder 502 to swing up and down. The striking cylinder 502 strikes and vibrates the grab bucket 3 back and forth. Under the action of vibration, the lees attached to the inner wall of the grab bucket 3 are fully dislodged and discharged, so that the material is discharged more fully.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
