Description

Technical Field

[0001] This utility model relates to a blade-type bucket reclaimer, belonging to the field of material reclaiming technology for earthen vat fermentation. Background Technology

[0002] In solid-state fermentation brewing, the fermentation mash is typically carried out by burying it deep in earthen vats. After fermentation, the mash needs to be removed from the vats and transferred to the next process. Traditional methods of removing the mash rely entirely on manual labor, using shovels, buckets, and other tools to dig layer by layer, which presents the following significant problems:

[0003] 1. High labor intensity and low efficiency.

[0004] The depth of the earthen cylinders is generally between 1.2m and 1.8m, and the volume of a single cylinder is between 0.8m³ and 1.5m³. Manual shoveling requires frequent bending and climbing, and the pure operation time for a single cylinder is 20 to 30 minutes. With the expansion of production scale, manual operation can no longer meet the needs of continuous and rhythmic production.

[0005] 2. High residual amount and large loss.

[0006] The bottom of the vat has a rounded transition, making it impossible to clean thoroughly manually. The thickness of the residual mash is usually ≥30mm, and the loss per vat is about 3% to 5%, which not only wastes raw materials but also affects hygiene between batches.

[0007] 3. Poor adaptability of automated equipment.

[0008] Although grab bucket and spiral reclaimers that have emerged in recent years can partially replace manual labor, they have revealed the following defects in practical applications: grab bucket reclaimers have a large opening and closing stroke and are prone to collision with the cylinder wall; after closing, the material in the center is loose and the grabbing amount is insufficient; the gap between the blades and the cylinder wall of spiral reclaimers is large and requires secondary manual cleaning; the spiral helix angle is fixed and sensitive to fluctuations in moisture content, making it prone to slippage and blockage.

[0009] Whether it's a grab bucket reclaimer or a screw reclaimer, neither of their devices can adjust their posture in real time during the lifting process, resulting in high digging resistance and a high rate of cylinder wall scratches; they also lack a bottom-support structure, so the remaining material at the bottom of the cylinder still needs to be manually cleaned.

[0010] 4. Risks of hygiene and cross-contamination.

[0011] Traditional equipment and manual operation both have problems such as multiple tool entries and exits and long exposure time of mash, which make it difficult to meet the requirements of clean transportation for food safety. Utility Model Content

[0012] This invention overcomes the shortcomings of existing technologies and provides a blade-type bucket reclaimer that can complete the excavation of the entire vat in one go, automatically adapt to the vat shape, and significantly reduce residue, thus achieving efficient, low-loss, and clean discharge of solid-state fermented mash.

[0013] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a blade-type bucket reclaimer, installed at the end of a lifting device, comprising:

[0014] The rotating part has a rotary platform and a frame fixedly connected thereto, the rotary platform can drive the entire material handling machine to rotate around a vertical axis;

[0015] The hinge portion is disposed on the frame and can be opened and closed within a certain range relative to the frame;

[0016] The bottom section is located on the frame and below the hinge section. It can form a variable-volume digging space together with the hinge section to dig out the entire vat of mash at once and reduce the amount of material left at the bottom of the vat.

[0017] Furthermore, the structure of the bottom part includes a motor reducer, a support rod, a rotating rod, and blades. The motor reducer is fixedly mounted on the frame. The support rod is a hollow tubular structure. The upper end of the support rod is fixedly mounted on the body of the motor reducer. The rotating rod passes through the support rod. The upper end of the rotating rod is connected to the power output end of the motor reducer. The lower end of the rotating rod extends out of the support rod and is connected to the blades. The motor reducer drives the blades to switch between closed and open states through the rotating rod.

[0018] Furthermore, the structure of the hinge portion includes an electric push cylinder, a guide rod, a connecting rod, and a hinge. The electric push cylinder and the guide rod are arranged in parallel, and both the electric push cylinder and the guide rod are fixedly mounted on the frame. The power end of the electric push cylinder is movably connected to one end of the connecting rod, and the other end of the connecting rod is movably connected to the hinge. The electric push cylinder drives the hinge to open and close through the connecting rod.

[0019] Furthermore, the hinge can open and close within a range of 0° to 90° relative to the frame.

[0020] Furthermore, the lower end of the support rod is sealed to the protruding part of the rotating rod.

[0021] Furthermore, the hinge is driven in the torque mode of the electric push cylinder, and the hinge remains in contact with the cylinder wall during its descent within the cylinder.

[0022] Furthermore, the blades can be parallel to the bottom of the cylinder when closed.

[0023] Compared with existing technologies, this invention offers the following advantages: It allows for one-time excavation of the entire vat, significantly shortening the work cycle compared to traditional manual methods. During material removal, the blades close parallel to the vat bottom, resulting in a residual mash thickness of ≤5mm and greatly reducing raw material loss. The hinges provide full-process wall-hugging guidance, preventing hard collisions between the excavation space and the vat wall, thus avoiding scratches and extending the lifespan of both the equipment and the vat. The rotating blades allow for drilling downwards, reducing resistance and saving energy. The rotary platform, electric pusher cylinder, and motor reducer are linked, with the action sequence controlled by a single PLC button, requiring only manual monitoring and significantly reducing labor intensity.

[0032] The present invention will be further described below with reference to specific embodiments.

[0033] like Figures 1-4 As shown, this utility model discloses a blade-type bucket reclaimer, installed at the end of a lifting device, comprising:

[0034] The rotating part 1 has a rotary platform 11 and a frame 12 fixedly connected thereto. The rotary platform 11 can drive the entire material handling machine to rotate around a vertical axis.

[0035] Hinge section 2, disposed on the frame 12, can open and close within a certain range relative to the frame 12. The structure of hinge section 2 includes an electric actuator 21, a guide rod 22, a connecting rod 23, and a hinge 24. The electric actuator 21 and guide rod 22 are arranged in parallel and are both fixedly mounted on the frame 12. The power end of the electric actuator 21 is movably connected to one end of the connecting rod 23, and the other end of the connecting rod 23 is movably connected to the hinge 24. The electric actuator 21 drives the hinge 24 to open and close via the connecting rod 23. The hinge 24 can open and close within a range of 0° to 90° relative to the frame 12.

[0036] The bottom-collecting part 3 is located on the frame 12 and below the hinge part 2. It can form a variable-volume digging space together with the hinge part 2 to achieve one-time digging of the entire vat of fermented mash and reduce the residual material at the bottom of the vat. The bottom-collecting part 3 has the following structure: it includes a motor reducer 31, a support rod 32, a rotating rod 33, and blades 34. The motor reducer 31 is fixedly mounted on the frame 12. The support rod 32 is a hollow tubular structure. The upper end of the support rod 32 is fixedly mounted on the body of the motor reducer 31. The rotating rod 33 passes through the support rod 32. The upper end of the rotating rod 33 is connected to the power output end of the motor reducer 31. The lower end of the rotating rod 33 extends out of the support rod 32 and is connected to the blades 34. The motor reducer 31 drives the blades 34 to switch between closed and open states through the rotating rod 33. The rotating rod 33 is connected to the three blades 34 by a planetary bevel gear drive structure. The bevel gear drives the blades 34 to rotate, so that they can switch between a horizontally closed state and an inclined open state.

[0037] In this embodiment, the lower end of the support rod 32 is sealed to the protruding part of the rotating rod 33.

[0038] In this embodiment, the hinge 24 is driven in the torque mode of the electric push cylinder 21, and the hinge 24 remains in contact with the cylinder wall during the process of descending in the cylinder.

[0039] In this embodiment, the blade 34 is parallel to the bottom of the cylinder when it is closed.

[0040] The working principle of this utility model:

[0041] The blade-type bucket reclaimer is installed at the end of the lifting device and rigidly connected to it via a quick-release flange. The lifting device moves the entire machine horizontally to directly above the target cylinder and slowly descends, aligning the centerline of the frame 12 with the centerline of the cylinder. The rotating platform 11 is activated, causing the frame 12 and all components mounted on it to rotate around the vertical axis, aligning the hinge 24 and blades 34 with the cylinder opening in the horizontal plane, completing circumferential positioning. The lifting device continues to descend; simultaneously, the electric pusher cylinder 21 extends its push rod, driving the hinge 24 to gradually open via the connecting rod 23. The guide rod 22 ensures linearity of movement, ensuring that the arc-shaped hinge 24 remains elastically attached to the inner wall of the cylinder throughout the descent, providing guidance and initial scraping. When the frame 12 approaches the surface of the mash, the motor reducer 31 starts, driving the rotating rod 33 to rotate the blades 34 at a set angle, forming a spiral drill bit shape. The lifting device continues to press down, and the blades 34 spirally cut into the mash layer, significantly reducing the digging resistance until the entire machine reaches the bottom of the cylinder. The moment the frame 12 touches the bottom of the cylinder, the motor reducer 31 reverses, and the blades 34 quickly rotate to a horizontal position, parallel to the bottom of the cylinder and closing to form a complete bottom catch. At this time, the hinges 24 continue to close under the action of the electric push cylinder 21, forming a closed digging space together with the closed blades 34, taking in the entire cylinder of mash at once. The lifting device drives the whole machine to rise, and the closed hinges 24 and blades 34 remain clamped, preventing mash from spilling; at the same time, the rotating platform 11 can cooperate with horizontal rotation to realize the transfer or unloading of mash. Since the blades 34 are finally parallel and attached to the bottom of the cylinder, the thickness of the residual mash at the bottom of the cylinder is controlled to ≤5mm, which is significantly lower than the residue of more than 30mm by manual or other equipment, meeting the design purpose of "reducing the residual material at the bottom of the cylinder".

[0042] At this point, the single-cylinder material extraction operation is complete, and no secondary manual cleaning is required throughout the entire process, truly achieving one-time full-volume excavation.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
