Description

Technical Field

[0001] The invention relates to the technical field of winemaking, in particular to a transfer device. Background Art

[0002] In the wine production line, automated production has become the development trend of the industry. In particular, the transportation of wine lees has always been a major problem that has troubled equipment manufacturers and wine companies. The wine lees need to be transported in the process of entering the cellar, leaving the cellar, and distilling the wine. The traditional transportation method is to transport the wine lees by using a crane and a bucket, and to clamp and release the wine lees by opening and closing the bucket. However, the bucket has a complex structure, is expensive, has a high cost, has a high failure rate, and has a small capacity, resulting in a large number of transportation times and low production efficiency. Summary of the invention

[0003] In view of the problems of complex structure and low transfer efficiency of the traditional bucket, the present invention provides a transfer device with simple structure and high degree of automation, which can realize automatic fixing and automatic unloading of the bucket.

[0004] The technical solution adopted by the present invention is: a transfer device includes a frame and a hopper arranged in the frame, a discharge port and a material door for opening and closing the discharge port are arranged at the bottom of the hopper, and a sling is arranged on the top of the frame; the sling includes a sling frame, a rotatable hook and a first power mechanism for driving the hook to rotate are arranged at the bottom of the sling frame, and the hook is used to fix the frame and the sling; a pulley is arranged on the lifting frame, and a steel wire rope is arranged on the pulley. The crane is connected to the sling through the steel wire rope. When the hopper is transferred, when the crane drives the sling to drop to the upper surface of the frame, the power mechanism drives the hook to rotate, and the hook is locked with the frame to complete the fixation of the hopper and the sling. Compared with the traditional method, the sling of the present invention can complete the automatic connection of the hopper, reduce the labor intensity and operation risks, improve work efficiency, save production costs, and the present invention has a simple structure, convenient operation, and a high degree of automation.

[0005] Furthermore, the first power mechanism includes an electric cylinder, the fixed end of the electric cylinder is connected to the sling frame, the movable end of the electric cylinder is connected to the middle part of the first torsion bar through a first pin plate, the first pin plate is fixedly connected to the first torsion bar, and the movable end of the electric cylinder is hinged to the first pin plate; the end of the first torsion bar is fixedly connected to a second pin plate, the second pin plate is hinged to a swivel pin through a second torsion bar, and the swivel pin is fixedly connected to a hook. The extension and retraction of the electric cylinder drives the first torsion bar to rotate, the first torsion bar drives the second torsion bar to extend and retract synchronously, and then drives the swivel pin to rotate, and the rotation of the swivel pin drives the hook to rotate synchronously during the rotation of the hook, so as to complete the disassembly and assembly of the hook and the frame. The ingenuity of the present invention lies in that the synchronous rotation of multiple hooks can be achieved by only using one electric cylinder and a set of torsion bar mechanisms, and it has a simple structure, stable power output, and low cost.

[0006] Furthermore, two proximity switches are arranged beside the pin. The two proximity switches are respectively arranged in two adjacent directions perpendicular to the pin. The proximity switches are used to detect the situation where the pin rotates in place. The two proximity switches respectively arranged in two adjacent directions perpendicular to the pin are used to limit the rotation angle of the pin to 90°, avoiding waste caused by excessive power output and making the connection between the spreader and the hopper more firm.

[0007] Furthermore, two limiting plates are arranged along the same axis at a certain distance beside the pin. The limiting plates play a limiting role. When the proximity switches fail or malfunction, the limiting plates can limit the rotation angle of the pin, avoiding the situation of the hopper unhooking and preventing corresponding safety accidents.

[0008] Furthermore, guide plates are evenly arranged at the bottom of the spreader frame. When the spreader descends to the upper surface of the rack, it plays a guiding role, making the docking between the spreader and the rack smoother.

[0009] Furthermore, a wire-winding column is arranged on the spreader frame, and a cable frame is arranged outside the wire-winding column. There are electrical equipment on the spreader, and the cables of the electrical equipment are wound around the wire-winding column. At the same time, the cable frame protects the cables. If the wire-winding column and the cable frame are not set, during the lifting and lowering process of the spreader, the cables are scattered on the spreader, which is easy to cause the cables to get stuck between the spreader and the hopper, causing wear or direct damage to the cables, and then affecting the operation of the equipment.

[0010] Furthermore, a self-opening door mechanism is arranged on the hopper. Compared with the traditional method of manually opening and closing the hopper door, the self-opening door mechanism of the present invention can automatically open or close the hopper door, reducing the manual labor intensity and operation risk, improving the work efficiency, saving the production cost, and having a simple structure, convenient operation and high automation degree.

[0011] Furthermore, the material door includes an arc-shaped bottom plate and side plates arranged on both sides in the width direction of the bottom plate; the self-opening mechanism includes an upper guide rod vertically arranged in the middle of the side of the frame and movably connected to the frame. A second power mechanism for driving the lifting of the upper guide rod is provided on the sling frame. The bottom of the upper guide rod is successively connected to the side plates through a first connecting plate and a second connecting plate. The upper guide rod is hinged to the first connecting plate, the first connecting plate is hinged to the second connecting plate, the second connecting plate is fixedly connected to the side plate, and the second connecting plate is hinged to the frame; a lower guide rod fixedly connected to the frame is arranged below the upper guide rod. A movable seat is slidably arranged on the lower guide rod, and the movable seat is hinged to the second connecting plate through a third connecting plate. During operation, the power mechanism drives the upper guide rod to descend. The upper guide rod drives the material door to rotate synchronously with the second connecting plate around the hopper through the first connecting plate. Since the upper guide rod is arranged in the middle of the side of the frame, during the process of the upper guide rod pressing down, the material door will rotate towards the outside of the frame; at the same time, as the upper guide rod descends, the movable seat is driven to descend on the lower guide rod through the third connecting plate, and the movable seat will also pull the material door to rotate synchronously with the second connecting plate through the third connecting plate, thereby opening the discharge port below the hopper. After the material is dumped, by using the gravity of the material door itself, the material door automatically returns to its position and rotates to the lower part of the material port to close the material port. The present invention drives the opening and closing of the material door through the self-opening mechanism to complete the dumping or storage of materials. Compared with the traditional manual opening and closing method, it reduces the labor intensity of workers, improves the production efficiency, reduces the production cost, and the device has a simple structure, convenient operation and high automation degree.

[0012] Furthermore, the second connecting plate is connected to the frame through a spring. After unloading, during the process of the material door returning to its position, the spring can pull the material door back to its position, making the material door return to its position more quickly and smoothly; at the same time, when the material door is in the closed state, the spring can also act on the material door to prevent the material door from swinging.

[0013] Furthermore, a fixed seat connected to the frame is arranged outside the upper guide rod, and the upper guide rod is movably connected to the fixed seat, which plays a guiding role and can ensure the stability of the upper guide rod during the lifting process; a pressing block is arranged at the top of the upper guide rod, and the second power mechanism applies force to the upper guide rod through the pressing block to prevent the upper guide rod from being damaged.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The sling of the present invention can complete the automatic connection of the hopper, reduces the labor intensity and operation risk of workers, improves the work efficiency, saves the production cost, and the present invention has a simple structure, convenient operation and high automation degree.

[0016] 2. The self-opening mechanism of the present invention can complete the automatic opening or closing of the material door, reduces the labor intensity and operation risk of workers, improves the work efficiency, saves the production cost, and has a simple structure, convenient operation and high automation degree.

[0017] 3. The proximity switch of the present invention can accurately control the rotation angle of the hook, avoiding waste caused by excessive power output and making the connection between the spreader and the hopper more firm.

[0018] 4. The wire winding post and cable frame of the present invention can collect and protect the scattered cables, avoid cable abrasion or damage, ensure the normal operation of the equipment, and extend the service life of the cables.

[0019] 5. The spring of the present invention can pull the feed door back to its position; at the same time, when the feed door is in the closed state, the spring can also act on the feed door to prevent the feed door from swinging. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] Example 1

[0032] Referring to Figures 1 to 7 , the transfer device of the present invention includes a frame 1 and a hopper 11 arranged inside the frame. The bottom of the hopper is provided with a discharge port and a hopper door 12 for opening and closing the discharge port. A lifting tool is arranged at the top of the frame; the lifting tool includes a lifting tool frame 2. A rotatable hook 21 and a first power mechanism 22 for driving the rotation of the hook are arranged at the bottom of the lifting tool frame. The hook is used to fix the frame and the lifting tool; a pulley 23 is arranged on the lifting frame, and a steel wire rope (not shown in the figure) is arranged on the pulley. The traveling crane is connected to the lifting tool through the steel wire rope. When transferring the hopper, when the traveling crane drives the lifting tool to descend to the upper surface of the frame, the power mechanism drives the hook to rotate, and the hook is locked with the frame to complete the fixation of the hopper and the lifting tool. Compared with the traditional method, the lifting tool of the present invention can complete the automatic connection of the hopper, reduce the labor intensity and operation risk of workers, improve the work efficiency, save the production cost, and the structure of the present invention is simple, the operation is convenient, and the degree of automation is high.

[0033] Referring to Figures 2 to 5 , the first power mechanism 22 of this embodiment includes an electric cylinder 221. The fixed end of the electric cylinder is connected to the lifting tool frame, and the movable end of the electric cylinder is connected to the middle part of the first torsion bar 224 through a first pin plate 222. The first pin plate 222 is fixedly connected to the first torsion bar 224, and the movable end of the electric cylinder is hinged to the first pin plate 222; a second pin plate 223 is fixedly connected to the end of the first torsion bar. The second pin plate 223 is hinged to the rotating pin 226 through a second torsion bar 225, and the rotating pin 226 is fixedly connected to the hook 21. The telescopic movement of the electric cylinder drives the rotation of the first torsion bar, and the first torsion bar drives the synchronous telescopic movement of the second torsion bar, thereby driving the rotation of the rotating pin. During the rotation of the rotating pin, the hook is driven to rotate synchronously to complete the disassembly and assembly of the hook and the frame. The ingenious part of the present invention is that only one electric cylinder and a set of torsion bar mechanisms can realize the synchronous rotation of multiple hooks, and its structure is simple, the power output is stable, and the cost is low.

[0034] Referring to Figure 5 , two proximity switches 24 are arranged beside the rotating pin in this embodiment. The two proximity switches are respectively arranged in two adjacent directions perpendicular to the rotating pin. The proximity switch is used to detect the situation where the rotating pin rotates in place. The two proximity switches respectively arranged in two adjacent directions perpendicular to the rotating pin are used to limit the rotation angle of the rotating pin to 90°, avoiding the waste caused by excessive power output, and also making the connection between the lifting tool and the hopper more firm.

[0035] Referring to Figure 5 , two limit plates 25 are arranged along the same axis at intervals beside the rotating pin in this embodiment. The limit plates play a limiting role. When the proximity switch fails or malfunctions, the limit plates can limit the rotation angle of the rotating pin to avoid the situation of the hopper unhooking and prevent corresponding safety accidents.

[0036] Refer to Figure 2 , in this embodiment, guide plates 26 are evenly arranged at the bottom of the spreader frame. When the spreader descends to the upper surface of the rack, it plays a guiding role, making the docking of the spreader and the rack smoother.

[0037] Refer to Figure 2 , in this embodiment, a wire winding post 27 is arranged on the spreader frame, and a cable frame 28 is arranged outside the wire winding post. There are electrical equipment on the spreader, and the cables of the electrical equipment are wound around the wire winding post, and at the same time, the cables are protected by the cable frame. If the wire winding post and the cable frame are not provided, during the lifting and lowering process of the spreader, the cables will be scattered on the spreader, which is likely to cause the cables to be stuck between the spreader and the hopper, causing wear or direct damage to the cables, and further affecting the operation of the equipment.

[0038] Refer to Figure 6 , in this embodiment, reinforcing ribs 16 are arranged in the hopper to strengthen the hopper.

[0039] Embodiment 2

[0040] Refer to Figure 6 and Figure 7On the basis of the first embodiment, the present embodiment is provided with a self-opening door mechanism 13 on the hopper. The material door 12 comprises an arc-shaped bottom plate 120 and side plates 121 arranged on both sides of the bottom plate in the width direction; the self-opening door mechanism 13 comprises an upper guide rod 130 arranged vertically in the middle of the side of the frame and movably connected to the frame, a second power mechanism 132 for driving the upper guide rod to rise and fall is provided on the hanger frame, the bottom of the upper guide rod is connected to the side plate 121 through the first connecting plate 133 and the second connecting plate 134 in sequence, the upper guide rod 130 is hinged to the first connecting plate 133, the first connecting plate 133 is hinged to the second connecting plate 134, the second connecting plate 134 is fixedly connected to the side plate 121, and the second connecting plate is hinged to the frame; a lower guide rod 131 fixedly connected to the frame is provided below the upper guide rod, a movable seat 136 is slidably provided on the lower guide rod, and the movable seat 136 is hinged to the second connecting plate 134 through the third connecting plate 135. During operation, the power mechanism drives the upper guide rod to descend, and the upper guide rod drives the material door to rotate synchronously with the second connecting plate around the hopper through the first connecting plate. Since the upper guide rod is arranged in the middle of the side of the frame, the material door will rotate toward the outside of the frame during the downward pressure of the upper guide rod; at the same time, as the upper guide rod descends, the movable seat is driven to descend on the lower guide rod through the third connecting plate, and the movable seat will also pull the material door to rotate synchronously with the second connecting plate through the third connecting plate, thereby opening the discharge port below the hopper. After the material is dumped, the material door automatically returns to its position by utilizing its own gravity, and rotates to the bottom of the material port to close the material port. The present invention drives the material door to open and close through a self-opening mechanism to complete the dumping or storage of materials. Compared with the traditional manual opening and closing method, it reduces the labor intensity, improves the production efficiency, and reduces the production cost. In addition, the device has a simple structure, is easy to operate, and has a high degree of automation.

[0041] Reference Figure 6 In this embodiment, the second connecting plate 134 is connected to the frame 1 through the spring 14. After unloading, during the process of the material door returning, the spring can pull the material door back to make the material door return faster and smoother; at the same time, when the material door is in a closed state, the spring can also act on the material door to prevent the material door from swinging.

[0042] Reference Figure 7 In this embodiment, a fixed seat 137 connected to the frame is arranged on the outer side of the upper guide rod. The upper guide rod is movably connected to the fixed seat to play a guiding role, which can ensure the stability of the upper guide rod during the lifting process; the upper guide rod 130 is movably connected to the fixed seat 137; a pressure block 15 is arranged on the top of the upper guide rod, and the second power mechanism applies force to the upper guide rod through the pressure block to avoid damage to the upper guide rod.

[0043] Reference Figure 1 The second power mechanism of this embodiment is a screw lift. The screw lift is a common power device in the prior art, which has the characteristics of compact structure, light weight, low noise, stable operation, and easy installation.

[0044] Referring to Figure 6 , there are two discharge ports and two feed doors in this embodiment. The two discharge ports increase the speed of material transfer, and the ingenuity of the present invention lies in that through a power mechanism and corresponding torsion bars, the two feed doors can be driven to rotate synchronously.

[0045] The feed door of this embodiment is integrally formed, making the feed door stronger and more stable.

[0046] Working principle: First, connect the spreader and the overhead crane. The two are connected by a steel wire rope. The overhead crane can drive the spreader to lift and lower through the steel wire rope, and the overhead crane can also drive the spreader to move horizontally. Keep the connected hopper in a horizontal state. The overhead crane drives the spreader to descend to the upper surface of the frame. At this time, the piston rod of the electric cylinder extends, and drives the rotating pin to rotate 90° through the first torsion bar and the second torsion bar in sequence. The rotating pin drives the hook to rotate synchronously. After the hook rotates, it fixes the hopper inside it, that is, the fixing of the hopper and the spreader is completed. When the hopper needs to be disassembled, the electric cylinder retracts.

[0047] Taking the process of entering the cellar as an example, after the distiller's grains are filled in the hopper, the overhead crane hoists the hopper above the cellar pool. The screw jack drives the upper guide rod to descend. The upper guide rod drives the feed door to rotate around the hopper synchronously with the second connecting plate through the first connecting plate. Since the upper guide rod is arranged in the middle of the side of the frame, during the process of the upper guide rod pressing down, the feed door will rotate towards the outside of the frame, as shown by the arrow in Figure 1 ; At the same time, as the upper guide rod descends, the movable seat is driven to descend on the lower guide rod through the third connecting plate, and the movable seat will also pull the feed door to rotate synchronously with the second connecting plate through the third connecting plate, thereby opening the discharge port below the hopper. After the material is poured out, the screw jack drives the screw rod to retract. Utilizing the gravity of the feed door itself, the feed door automatically returns to its position and rotates to the lower part of the feed port to close the feed port. The present invention drives the opening and closing of the feed door through the self-opening mechanism to complete the dumping or storage of materials. Compared with the traditional method, the self-opening mechanism of the present invention can automatically open or close the feed door, reducing the labor intensity and operation risk of workers, improving work efficiency, saving production costs, and having a simple structure, convenient operation and high automation degree.

[0048] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
