DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 3 As shown, the present invention provides a multi-petal grab crane for light-flavor liquor, including a main beam and a trolley end beam 100, and also includes a transfer trolley 200, which is installed on the main beam and the trolley end beam 100 to drive the grab to move on the horizontal plane; A grab machine 500, which is installed on the transfer trolley 200; Power supply cables 400, which are installed on the main beam and the trolley end beam 100 to supply power to the transfer trolley 200 and the grab bucket 500; The hopper transfer machine 300 is installed on the main beam and the end beam of the cart 100 to receive and transfer the hopper; Among them, the grab machine 500 includes an upper mounting frame 501 fixedly installed on the bottom of the transfer trolley 200, the bottom of the upper mounting frame 501 is connected to the lower mounting frame 503 through a scissors support device 502, and an electric hoist 506 is also installed on the transfer trolley 200. The electric hoist 506 is connected to the lower mounting frame 503 through a wire rope and a movable pulley 504, and a grab 505 is installed in the middle of the lower mounting frame 503.

[0020] The staff operates the transfer trolley 200 above the crane to move horizontally, so that it moves to the top of the wine-making vat to be processed. The auxiliary projection light can be used to determine whether the position is directly above the corresponding wine-making vat. Then the electric hoist 506 is controlled to descend. When the grab bucket 505 is close to the wine-making vat, the position of the transfer trolley 200 can be fine-tuned according to the actual situation to prevent the grab bucket 505 from colliding with the edge of the wine-making vat. Then the electric hoist 506 is continued to descend to allow the grab bucket 505 to penetrate into the wine-making vat to grab the wine tank. Then the grab bucket 505 with the full wine tank is controlled to come out of the wine-making vat and put the wine tank into the hopper of the hopper conveyor 300, thus reciprocating until the hopper is full. The hopper is transferred to the forklift through the hopper conveyor 300 for transportation, and the next hopper is continued to be filled, so that the wine tanks in all the wine-making vats are emptied.

[0021] like Figure 5As shown, the grab bucket 505 includes a base 5051 fixedly mounted on the lower mounting frame 503, and a plurality of bucket bodies 5053 are connected to the base 5051 through a hinge shaft and a connecting rod 5052. An electric telescopic rod 5056 is installed at the center position of the upper surface of the lower mounting frame 503. The plurality of bucket bodies 5053 are hingedly connected through an articulated seat 5054. The telescopic end of the electric telescopic rod 5056 is connected to the articulated seat 5054 to drive it to move linearly. A plurality of linear bearings 5055 are arranged between the articulated seat 5054 and the base 5051 for linear guidance.

[0022] The electric telescopic rod 5056 is controlled to extend to drive the articulated seat 5054 to move up and down, and the grab bucket is controlled to open and close under the joint action of the base 5051, the connecting rod 5052 and the bucket body 5053 connecting rod mechanism to grab and release the wine tank. A linear bearing 5055 is arranged between the base 5051 and the articulated seat 5054 to limit the articulated seat 5054 in the horizontal direction, so that the articulated seat 5054 will not move horizontally when grabbing or releasing.

[0023] like Figure 1-Figure 3 As shown, the hopper transfer machine 300 includes a trolley power supply device 301 , a transfer lower trolley 302 is installed below the trolley power supply device 301 , the transfer lower trolley 302 is hoisted with a hopper frame 304 through an anti-sway device 303 , and the hopper is placed on the hopper frame 304 .

[0024] The transfer trolley 302 is used to lift the hopper frame 304 through the anti-sway device 303 for transferring the hopper. Figure 2 As shown, a transport channel is provided between the two wine-making areas, and a hopper placement platform is provided in the transport channel. When the hopper is full, it is placed on the designated placement platform. The hopper filled with wine tanks is transported away by a forklift coming from the transport channel, and the empty hopper is placed on another placement platform. The transfer trolley 302 drives the hopper frame 304 to transfer to the empty hopper, installs it on the hopper frame 304, lifts it away, and continues to cooperate with the grabber 500 to grab and transport the wine tank. At this point, the multi-petal grabber crane for light-flavor liquor completes a working cycle.

[0025] like Figure 3 As shown, an electric push rod and a pin are also provided on the hopper frame 304 . The electric push rod drives the pin to be inserted into the pin hole on the hopper to fix the position of the hopper on the hopper frame 304 .

[0026] The electric push rod and the pin are arranged on the hopper frame 304. The corresponding positions of the electric push rod and the pin on the hopper frame 304 match the corresponding positions of the small holes on the hopper. When the pin is engaged in the pin hole of the hopper by the action of the electric push rod, the hopper is loaded, otherwise it is released. When the hopper frame 304 is equipped with an empty hopper, it falls from the top of the hopper. After the positions of the pin and the pin hole are aligned, the electric push rod is controlled to drive the pin to be inserted into the pin hole to complete the docking.

[0027] like Figure 1 and Figure 4 As shown, the upper mounting frame 501, the scissor support device 502 and the lower mounting frame 503 together constitute an anti-sway scissor support device, and a group of scissor support devices 502 are respectively provided on the four edges of the upper mounting frame 501 and the lower mounting frame 503, and the four groups of scissor support devices 502 are arranged in a hole shape. It can effectively prevent the grab bucket device from shaking or moving horizontally in the horizontal direction, and ensure the accuracy of the grab bucket falling.

[0028] like Figure 4 As shown, the upper mounting frame 501 and the upper transfer trolley 200 are rigidly connected, and the movable pulley 504 is installed on the upper surface of the lower mounting frame 503. The upper mounting frame 501 and the upper transfer trolley 200 are fixedly connected by bolts, and the movable pulley 504 is fixedly installed on the upper surface of the lower mounting frame 503. The electric hoist 506 drives the steel wire rope to drive the movable pulley 504 to lift the lower mounting frame 503. In this way, the lifting and grabbing of the grab bucket 505 is completed.

[0029] like Figure 4-Figure 6 As shown, 5 to 8 bucket bodies 5053 of the grab bucket 505 are provided, and the shape of the bucket body 5053 fits the inner surface of the wine-making vat. Figure 6 The figure shows a grab bucket 505 provided with a bucket body 5053, which can be closely attached to the inner wall of the wine making vat; The outer diameter of the upper part of the grab bucket 505 body is 650 mm and the height is 1800 mm.

[0030] The shape of the bucket 5053 is designed and manufactured in accordance with the internal contour of the ground cylinder, and is larger at the top and smaller at the bottom. The outer diameter of the grab bucket is slightly smaller than the inner diameter of the ground cylinder. According to the survey results, the maximum inner diameter of the ground cylinders of several wineries around Fenjiu Factory is about 700mm, so the upper outer diameter of the ground cylinder grab bucket is designed to be about 650mm, and the height of the grab bucket body is about 1800mm. The actual size (outer diameter and height) can be adjusted accordingly according to the size of the user's ground cylinder. The head of the grab bucket is in the shape of a trumpet, such as Figure 4 As shown in the figure, the grab bucket can be prevented from shrinking inwards during insertion into the ground tank. At the same time, a piece of food-grade soft silicone is wrapped around the head of the grab bucket and fixed with countersunk screws or rivets to prevent the grab bucket from scratching the winemaking ground tank.

[0031] like Figure 7As shown, the grab bucket 505 can be replaced by a rotary drilling module 507; The rotary drilling module 507 includes a rotary drilling spiral barrel 5071 rigidly mounted below the lower mounting frame 503, a movable base 5072 is mounted on the upper end of the rotary drilling spiral barrel 5071 through a shaft sleeve, a gear plate 5073 is mounted above the movable base 5072, the gear plate 5073 is meshed and driven through a driving gear 5076, a conveying auger 5077 is arranged inside the rotary drilling spiral barrel 5071, and the conveying auger 5077 is driven by a driving motor arranged above it, a discharge pipe 5070 is fixedly mounted above the lower mounting frame 503, and the discharge pipe 5070 is linearly connected to the inner cavity of the rotary drilling spiral barrel 5071.

[0032] The rotary drilling module 507 is an alternative embodiment of the grab bucket 505. It mainly lowers the rotary drilling spiral barrel 5071 into the wine tank along with the electric hoist, and drives the conveying auger 5077 inside the rotary drilling spiral barrel 5071 through the motor to rotate and enter the vertical conveying wine tank discharge pipe 5070, and connects the pipeline at the discharge pipe 5070 to the hopper to receive the material.

[0033] like Figure 7 As shown, a sleeve 5074 is slidably installed on the surface of the rotary drilling auger 5071 along the spiral track groove, a plurality of multi-stage telescopic positioning rods 5075 are connected between the sleeve 5074 and the moving base 5072, three elastic telescopic rods 5078 are fixed at equal angles on the extended edge of the sleeve 5074, and a smoothing rod 5079 is connected to the telescopic end of the elastic telescopic rod 5078, and the smoothing rod 5079 is supported on the inner wall of the wine-making tank.

[0034] The outer surface of the rotary excavation spiral barrel 5071 is provided with a spiral groove, and the sliding sleeve 5074 which is sleeved on the outer periphery of the spiral groove and movably engaged with the spiral groove can be lifted and lowered during the rotation process. The conveying auger 5077 will cause the surface of the wine tank to be uneven and the edge will be piled up during the vertical rotary excavation and transportation of the wine tank, and the wine tank cannot be actively and effectively gathered to the middle to be dug out by the conveying auger 5077. Therefore, an elastic telescopic rod 5078 and a smoothing rod 5079 assembly are arranged on the sliding sleeve 5074. The driving gear 5076 engages with the transmission gear disc 5073 to rotate, and then the dynamic base 5072 rotates, and the sliding sleeve 5074 is driven to rotate synchronously through the multi-stage telescopic positioning rod 5075 that can be extended and horizontally limited. Then the sliding sleeve 5074 rotates downward and cooperates with the smoothing rod 5079 to rotate and smooth the wine tank, and can also wipe off the wine tank adhering to the inner wall of the winemaking vat and transport it together, so the transportation efficiency is high. The design of the elastic telescopic rod 5078 is to match the changing 60 inner wall diameter.

[0035] like Figure 7 As shown, the leveling rod 5079 is an L-shaped rod, and the horizontal rod of the leveling rod 5079 is horizontal on the wine tank.

[0036] The vertical section of the L-shaped rod is used to erase the wine grooves on the inner wall of the wine-making jar, while the horizontal section is used to level the wine grooves in the wine-making jar to promote them to gather toward the middle.

[0037] The working principle and use process of the present invention: The staff operates the transfer trolley 200 above the crane to move horizontally, so that it moves to the top of the wine-making vat to be processed. The auxiliary projection light can be used to determine whether the position is directly above the corresponding wine-making vat. Then the electric hoist 506 is controlled to descend. When the grab bucket 505 is close to the wine-making vat, the position of the transfer trolley 200 can be fine-tuned according to the actual error situation to prevent the grab bucket 505 from colliding with the edge of the wine-making vat. Then the electric hoist 506 is continued to descend to allow the grab bucket 505 to penetrate into the wine-making vat to grab the wine tank. Then the grab bucket 505 with the full wine tank is controlled to come out of the wine-making vat and put the wine tank into the hopper of the hopper conveyor 300, thus reciprocating until the hopper is full. The hopper is transferred to the forklift through the hopper conveyor 300 for transportation, and the next hopper is continued to be filled, so that the wine tanks in all the wine-making vats are emptied.
