Description

Technical Field

[0001] The utility model relates to the technical field of grabbing machines, in particular to a grabbing machine with an anti-dropping structure. Background Art

[0002] Sprouts are made by cutting the tender stems of mustard into shreds and pickling them. There are two types: salty and sweet. Sprouts are tender, crisp, sweet and fragrant. In addition to being used as a base for braised pork, they are also used for seasoning, such as making soup to enhance the flavor, making noodles and meat stuffing, etc. During the pickling process, the sprouts need to be placed in a cellar first. After pickling, the sprouts can be taken out of the cellar by a grabber. The existing grabber still has certain defects when used.

[0003] The overall operation of the grabbing machine in the prior art is relatively simple, and the position of the grabbing machine can be moved by a crane. Since there is a certain gap between the grabbing arms on the grabbing machine, some sprouts will fall from the gap between the grabbing arms during the process of grabbing sprouts, which reduces the grabbing efficiency of the grabbing arms. Utility Model Content

[0004] The utility model aims to provide a grabbing machine with an anti-dropping structure to solve the problem that sprouts are easily dropped by the grabbing machines currently on the market as mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grabbing machine with an anti-drop structure, comprising: a crane hook, a motor, a mounting frame, a connecting plate, a grab arm and a connecting block, a motor is suspended at the bottom of the crane hook, a mounting frame is installed at the bottom of the motor, the bottom of the mounting frame is connected to the connecting plate through a rotating shaft, a grab arm is welded to the outside of the connecting plate, a connecting block is welded to the top of the connecting plate, a clamping rod is movably connected to the inside of the connecting block, a moving block is welded to the end of the clamping rod, a plug-in block is plugged into the inside of the connecting block, a spring is connected to the inside of the plug-in block, one end of the spring is connected to a trapezoidal clamping block, a T-shaped block is plugged into the inside of the connecting plate, and an arc-shaped baffle is welded to the outside of the T-shaped block.

[0006] Preferably, a locking structure is formed between the clamping rod and the T-shaped block, and a sliding structure is formed between the T-shaped block and the connecting plate.

[0007] Preferably, a plug-in structure is formed between the plug-in block and the connecting block.

[0008] Preferably, a fixing block is welded on the top of the mounting frame, and a threaded rod is connected inside the fixing block via a bearing.

[0009] Preferably, the outer side of the threaded rod is threadedly connected to a slider, and the outer side of the slider is welded with a pressure plate.

[0010] Preferably, a limiting column is welded to the bottom of the pressing plate, and extension plates are welded to both sides of the motor close to the pressing plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are: the grabber with an anti-drop structure can drive the card rod to move when the moving block moves, and can drive the T-shaped block to move when the arc-shaped baffle moves. When the arc-shaped baffle moves between the two sets of grab arms, the end of the T-shaped block can be inserted into the inside of the connecting plate. When the moving block is released, the moving block can fall by its own gravity. When the extension plate is removed from the top of the mounting frame, the motor can be quickly maintained. Through this simple and convenient method, the motor can be quickly disassembled and maintenance operations can be performed.

[0012] 1. The grabber can grab the sprouts at the designated position through the grabber arms. Since there are gaps between the grabber arms, the sprouts are easy to fall, which affects the grabbing efficiency of the grabber. When the moving block moves, it can drive the clamping rod to move. When the arc baffle moves, it can drive the T-shaped block to move. When the arc baffle moves between the two sets of grabber arms, the end of the T-shaped block can be plugged into the inside of the connecting plate. When the moving block is released, the moving block can fall by its own gravity, and the end of the clamping rod will fall into the inside of the T-shaped block. When the plug-in block moves , which can drive the trapezoidal block to move. When the end of the plug-in block is plugged into the inside of the connecting block, the inclined surface of the trapezoidal block will be squeezed by the connecting block. When the end of the plug-in block moves to the surface of the moving block, the trapezoidal block can be reset by the compression spring. When the trapezoidal block is reset, the plug-in block can be fixed on the connecting block. The plug-in block can limit the moving block and the card rod, so that the arc baffle can be installed between each set of gripper arms. The arc baffle can prevent the sprouts from falling from the gap between each set of gripper arms, thereby improving the gripping efficiency of the gripper.

[0013] 2. Motor failure is inevitable during the use of the grabber. Since the motor is usually fixed to the mounting frame by multiple sets of bolts, it is inconvenient to disassemble and maintain the motor. When the threaded rod rotates, it can drive the slider to slide threadedly. When the slider thread slides, it can drive the pressure plate to move. While the pressure plate slides, it can drive the limit column to move. When the pressure plate rises from the surface of the extension plate to the specified position, the limit column can slide out from the inside of the extension plate. When the motor moves, it can drive the extension plate to move. When the extension plate is removed from the top of the mounting frame, the motor can be quickly maintained. This simple and convenient method can quickly disassemble the motor and perform maintenance operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the utility model provides a technical solution: a grabbing machine with an anti-drop structure, comprising: a crane hook 1, a motor 2, a mounting frame 3, a connecting plate 4, a grab arm 5 and a connecting block 6;

[0022] A motor 2 is suspended at the bottom of the crane hook 1, a mounting frame 3 is installed at the bottom of the motor 2, a connecting plate 4 is connected to the bottom of the mounting frame 3 through a rotating shaft, and a gripper arm 5 is welded to the outer side of the connecting plate 4;

[0023] The connecting block 6 is welded on the top of the connecting plate 4. The connecting block 6 is movably connected with a clamping rod 7 inside. A moving block 8 is welded on the upper end of the clamping rod 7. A plug-in block 9 is plugged into the connecting block 6. A spring 10 is connected to the plug-in block 9. One end of the spring 10 is connected to a trapezoidal clamping block 11. A T-shaped block 12 is plugged into the connecting plate 4. An arc-shaped baffle 13 is welded on the outside of the T-shaped block 12. A clamping structure is formed between the clamping rod 7 and the T-shaped block 12. A sliding structure is formed between the T-shaped block 12 and the connecting plate 4. A plug-in structure is formed between the plug-in block 9 and the connecting block 6.

[0024] During specific implementation, the grabbing machine can grab the sprouts at the specified position through the grab arms 5. Since there are gaps between the grab arms 5, the sprouts are easy to fall, which affects the grabbing efficiency of the grabbing machine. For this reason, the moving block 8 can be pulled upward. When the moving block 8 moves, it can drive the card rod 7 to move. When the moving block 8 rises to the specified position, the arc baffle 13 can be pushed. When the arc baffle 13 moves, it can drive the T-shaped block 12 to move. When the arc baffle 13 moves between the two groups of grab arms 5, the end of the T-shaped block 12 can be inserted into the inside of the connecting plate 4, and the moving block 8 can be released at this time. When the moving block 8 is released, the moving block 8 can be lowered by its own gravity When the plug-in block 9 moves, the trapezoidal block 11 can be driven to move. When the end of the plug-in block 9 is plugged into the connecting block 6, the inclined surface of the trapezoidal block 11 will be squeezed by the connecting block 6. When the trapezoidal block 11 is squeezed, the spring 10 can be compressed and slid into the plug-in block 9. When the end of the plug-in block 9 moves to the surface of the moving block 8, the trapezoidal block 11 can be reset by compressing the spring 10. When the trapezoidal block 11 is reset, the plug-in block 9 can be fixed on the connecting block 6. The plug-in block 9 can limit the moving block 8 and the card rod 7, thereby installing the arc baffle 13 between each group of grabber arms 5.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the arc-shaped baffle 13 can prevent the sprouts from falling from the gap between each group of gripper arms 5, thereby improving the gripping efficiency of the gripper.

[0026] See also Figure 1 and Figure 5 It can be seen that a fixed block 14 is welded to the top of the mounting frame 3, the interior of the fixed block 14 is connected to a threaded rod 15 through a bearing, the outer side of the threaded rod 15 is threadedly connected to a slider 16, a pressure plate 17 is welded to the outer side of the slider 16, a limiting column 18 is welded to the bottom of the pressure plate 17, extension plates 19 are welded to both sides of the motor 2 close to the pressure plate 17, and two groups of fixed blocks 14 are symmetrically arranged about the center of the mounting frame 3.

[0027] During specific implementation, it is inevitable that the motor 2 will fail during the use of the grabber. Since the motor 2 is usually fixed to the mounting frame 3 by multiple sets of bolts, it is inconvenient to disassemble and maintain the motor 2. For this reason, the two sets of threaded rods 15 can be rotated. When the threaded rods 15 rotate, the slider 16 can be driven to slide threadedly. When the slider 16 slides threadedly, the pressure plate 17 can be driven to move. When the pressure plate 17 moves, it can slide with the fixed block 14. While the pressure plate 17 slides, it can drive the limit column 18 to move. When the pressure plate 17 rises from the surface of the extension plate 19 to the specified position, the limit column 18 can slide out from the inside of the extension plate 19. At this time, the motor 2 can be pulled horizontally. When the motor 2 moves, it can drive the extension plate 19 to move. When the extension plate 19 is removed from the top of the mounting frame 3, the motor 2 can be quickly maintained.

[0028] See also Figure 1 and Figure 5 It can be seen that the motor 2 can be quickly disassembled and maintained in this simple and convenient manner.

[0029] To sum up, when using the grabbing machine with an anti-drop structure, the grabbing arm 5 can be moved to a specified position through the crane hook 1. When the motor 2 is running, the connecting plate 4 can be driven to rotate, so that the sprouts can be grabbed through the grabbing arm 5. The operation is simple and the grabbing is convenient. The grabbing machine is a prior art and will not be described in detail here. The plug-in block 9 can limit the moving block 8 and the card rod 7, so that the arc baffle 13 can be installed between each group of grabbing arms 5. The arc baffle 13 can prevent the sprouts from falling from the gap between each group of grabbing arms 5, thereby improving the grabbing efficiency of the grabbing machine. When the motor 2 moves, it can drive the extension plate 19 to move. When the extension plate 19 is removed from the top of the mounting frame 3, the motor 2 can be quickly maintained. Through this simple and convenient method, the motor 2 can be quickly disassembled and maintained. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
