Description

Technical Field

[0001] This utility model specifically relates to a flip-over, air-avoiding throwing device. Background Technology

[0002] In the baijiu brewing industry, the still, as the core equipment for distillation, directly affects brewing efficiency and liquor quality through its operation in conjunction with the fermented mash. Currently, there are many technical bottlenecks in the still's mash-sprinkling and lid-opening / closing processes, severely restricting production efficiency: for example, traditional mash-sprinkling devices are mostly fixed installations, unable to be adjusted in position according to the still's lid-opening / closing requirements. Before each still lid-opening or closing operation, the still must be manually moved or the sprinkling device disassembled and repositioned, making the process cumbersome. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a flip-over, air-avoiding throwing device. A flip-up, air-avoiding spraying device includes a frame, a movable frame rotatably mounted on the frame, the spraying device being mounted on the movable frame, and a connecting member between the movable frame and the frame capable of locking the movable frame to rotate.

[0004] In one embodiment, the connecting member includes a limiting member fixedly disposed on the movable frame and a rotating member rotatably disposed on the frame, wherein the rotating member is provided with an annular member that can engage with the limiting member.

[0005] In one embodiment, the annular component includes a pin inserted through the rotating component and U-shaped inserts inserted at both ends of the pin. The U-shaped inserts are respectively provided with external threads at both ends, and a first limiting nut is threadedly fitted on both sides of the pin on the external threads.

[0006] In one embodiment, the limiting member has a recessed groove on the side opposite to the rotating member, and one end of the annular member can be engaged in the groove as the rotating member rotates.

[0007] In one embodiment, the frame is provided with support portions spaced apart vertically, and the movable frame has a support rod protruding from its movable end. The support rod can rotate with the movable frame and fit between the two support portions.

[0008] In one embodiment, the support includes pulleys rotatably mounted on the frame.

[0009] In one embodiment, a connecting rod is provided at the center of one side of the pulley, the connecting rod is inserted into the frame, and a second limiting nut is threadedly fitted on the connecting rod.

[0010] In one embodiment, the scattering device includes a hopper mounted on a movable frame, a rotating shaft rotatably mounted on the movable frame at the center of the hopper, a connecting frame mounted on the rotating shaft below the hopper, a belt conveyor mounted on the connecting frame, and a first motor mounted on the frame capable of driving the rotating shaft to rotate.

[0011] In one embodiment, a movable frame is provided on the connecting frame below the hopper, which can move back and forth along the radial direction of the hopper. The belt conveyor is provided on the movable frame. A transmission rack is fixed on one side of the movable frame. The length direction of the transmission rack is parallel to the radial direction of the hopper. A second motor is provided on the connecting frame. The drive shaft of the second motor is provided with a drive gear that can mesh with the transmission rack.

[0012] In summary, the advantages of this utility model over the prior art are: This invention utilizes the rotational engagement of the frame and the movable frame, coupled with a connecting component based on the "crank-connecting rod-dead-point self-locking" principle. Locking and unlocking of the movable frame can be achieved simply by rotating the rotating component, without disassembly or the use of complex tools. When opening and closing the pot lid, rotating the rotating component releases the self-locking mechanism, causing the movable frame to quickly rotate and avoid airflow. After opening and closing the lid, rotating the rotating component in the opposite direction puts the connecting component into a dead-point self-locking state, ensuring stable positioning of the movable frame.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 4 The present invention preferably provides a flip-over, air-avoiding spraying device, including a frame 1, on which a movable frame 2 is rotatably mounted, and the spraying device 3 is mounted on the movable frame 2. A connecting member 4 capable of locking the movable frame 2 to rotate is provided between the movable frame 2 and the frame 1.

[0015] Specifically, through the rotational engagement of the frame and the movable frame, coupled with connecting components based on the "crank-connecting rod-dead-point self-locking" principle, the movable frame can be locked and unlocked simply by rotating the rotating component, without the need for disassembly or complex tools. When the pot 100 is opening and closing, rotating the rotating component releases the self-locking, and the movable frame drives the spraying device to quickly rotate and avoid airflow; after the opening and closing of the cover is completed, rotating the rotating component in the opposite direction puts the connecting component into the dead-point self-locking state, and the movable frame is stably positioned.

[0016] Furthermore, the connecting member 4 includes a limiting member 5 fixedly mounted on the movable frame 2, and a rotating member 6 rotatably mounted on the frame 1. The rotating member 6 is provided with an annular member 7 that can engage with the limiting member 5. Specifically, one end of the rotating member is connected to the frame via a hinge (hinge center point O1), and the other end has a through hole (point O2, 120mm from point O1).

[0017] Furthermore, the annular component 7 includes a pin 71 inserted into the rotating component 6, and U-shaped inserts 72 inserted into both ends of the pin 71. Each end of the U-shaped insert 72 has an external thread 73, and a first limiting nut 74 is threaded onto each side of the pin 71 on the external thread 73. Furthermore, the limiting component 5 has a recessed groove on the side opposite to the rotating component 6, allowing one end of the annular component 7 to rotate with the rotating component 6 and engage in the groove. Specifically, the operator rotates the rotating component (crank) clockwise, causing the annular component (connecting rod) to rotate around point O2 until the end of the U-shaped insert engages in the limiting component's groove (point O3). Through structural dimension design (O1O2 length 120mm, O2O3 length 105mm, O1O3 length 225mm), it is ensured that the rotating part (O1O2) and the ring part (O2O3) are completely collinear (O1-O2-O3 are collinear), and the mechanism enters the dead point position. At this time, the downward load borne by the movable frame is transmitted to the ring part through the limiting part, generating a tensile force F along the O2O3 direction. This tensile force acts on point O1 along the axis of the rotating part (O1O2 direction), and the torque about point O1 is M=F×L (L is the perpendicular distance from point O1 to the line of action of the tensile force F). Since F is along the O1O2 axis, L=0, so M=0, the rotating part cannot rotate, and the ring part cannot disengage from the slot, realizing the self-locking of the movable frame. When the movable frame needs to be flipped, the operator applies an external force (approximately 15N) perpendicular to the axis of the rotating component, causing the rotating component to rotate slightly around point O1 (rotation angle 5-8°), breaking the collinear state of O1-O2-O3. At this time, the pulling force F generates a non-zero torque on point O1, driving the rotating component to rotate, and the ring component disengages from the slot, completing the unlocking. The operation requires no tools and is convenient and efficient.

[0018] Furthermore, the frame 1 is provided with support parts 9 spaced vertically, and the movable frame 2 has a support rod 10 protruding from its movable end. The support rod 10 can rotate with the movable frame 2 and fit between the two support parts 9. When the movable frame is flipped to the working position, the support rod fits between the upper and lower pulleys, providing auxiliary support for the movable frame.

[0019] Furthermore, the support 9 includes a pulley 91 rotatably mounted on the frame 1. Further, a connecting rod is provided at the center of one side of the pulley 91, the connecting rod passing through the frame 1, and a second limiting nut 93 is threaded onto the connecting rod 92. This ensures that the pulley can smoothly engage with the upper and lower pulleys when rotating with the movable frame, forming auxiliary support, and that the pulley position is fixed by tightening the nut, while ensuring that the pulley can rotate flexibly, facilitating pulley replacement.

[0020] Furthermore, the spreading device 3 includes a hopper 31 mounted on a movable frame 2. A rotating shaft 32 is rotatably mounted on the movable frame 2 at the center of the hopper 31. A connecting frame 33 is mounted on the rotating shaft 32 below the hopper 31. A belt conveyor 34 is mounted on the connecting frame 33. A first motor 35 is mounted on the frame 1 to drive the rotating shaft 32 to rotate. Specifically, the first motor drives the rotating shaft to rotate, thereby causing the belt conveyor to rotate circumferentially around the rotating shaft. This guides the material from the hopper to the belt conveyor, where it is then circumferentially spread.

[0021] Furthermore, a movable frame 36 is provided on the connecting frame 33 below the feeding hopper 31, capable of reciprocating radially along the feeding hopper 31. The belt conveyor 34 is mounted on the movable frame 36. A transmission rack 37 is fixedly provided on one side of the movable frame 36. The length direction of the transmission rack 37 is parallel to the radial direction of the feeding hopper 31. A second motor 38 is provided on the connecting frame 33. The drive shaft of the second motor 38 is provided with a drive gear 39 that can mesh with the transmission rack 37. Specifically, two sliders adapted to the sliding groove of the connecting frame are welded to the bottom of the movable frame, so that the movable frame can slide back and forth radially along the feeding hopper along the sliding groove. Then, the second motor drives the gear to mesh with the transmission rack, driving the movable frame to move at a uniform speed, so that the mash is evenly spread into the still 100, avoiding local accumulation or scattering.

[0022] In summary: The device's workflow (taking the feeding of fermented mash in the 100-cell still as an example): Initial state: The movable frame is in a free-standing position (90° angle with the frame), the annular component is not engaged in the limiting slot, the belt conveyor, the first motor, and the second motor are all stopped, and the 100-cell still is closed. Opening the 100-cell still: Without moving the scattering device, directly start the 100-cell still opening mechanism (such as a hydraulic push rod). Because the movable frame is free-standing, the opening process is uninterrupted, and the opening is completed within 30 seconds. Remove the still lid. Movable frame reset and locking: The operator manually flips the movable frame downwards until the support rod is engaged between the upper and lower pulleys (the movable frame is horizontal). Then, rotate the rotating component clockwise to engage the end of the annular component in the limiting slot. Confirm that the rotating component and the annular component are collinear (no looseness felt). The movable frame self-locks and is fixed, taking approximately 40 seconds. Sprinkling of fermented mash: Start the first motor, which drives the connecting frame, moving frame, and belt conveyor to rotate via the rotating shaft. Adjust the discharge angle of the belt conveyor to 40°. Start the second motor, which drives the moving frame to reciprocate radially along the discharge hopper. The fermented mash is fed into the discharge hopper via the feeding conveyor belt. The fermented mash falls from the discharge hopper onto the belt conveyor and is evenly sprinkled into the still 100. No manual intervention is required during the sprinkling process. Completion of sprinkling and clearing: When the fermented mash in the still 100 has been added to the set amount (approximately 80% of the volume), stop feeding. After there is no residual fermented mash on the belt conveyor, turn off the first and second motors. Rotate the rotating part counterclockwise to release the self-locking mechanism and flip the moving frame to the clearing position. Start the lid-closing mechanism of the still 100 to close the lid and enter the distillation process. The entire process takes about 5 minutes.
