Abstract
Description
Technical Field
[0001] The utility model relates to a material lifting mechanism with a feeding trolley, belonging to the technical field of feeding devices. Background Art
[0002] Feeder trolleys are widely used in mining, electric power, metallurgy, coal, building materials and other industries. They facilitate overall material distribution and can maximize the use of the site for material accumulation or distribution. In addition, feeder trolleys have the characteristics of compact and reasonable structure, reliable use, long life, easy maintenance and low maintenance cost. Regular inspection and maintenance can ensure its long-term stable operation.
[0003] However, current feeding trolleys generally do not have material lifting mechanisms, and materials are transported manually. Generally, dozens of kilograms of materials must be lifted to a height of at least one meter, plus there is a material pouring action. The labor intensity of the operators is too high and the efficiency is low at the end of the day. Although a chain hoist can be used as a power supply unit, the chain hoist method is expensive, requires a large installation height and occupies a large space, and cannot be used when the customer's site is limited. Instead, a material hoist that is not powered by a chain hoist is used. However, there is a certain distance between the pouring position of the lifting hopper and the position where the material is required to fall. Either the material cannot fall to the specified position, or the hopper may interfere with the main equipment by lengthening the hopper, which is inconvenient to use. For this reason, we provide a material lifting mechanism with a feeding trolley to solve the above problems. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a material lifting mechanism with a feeding trolley to solve the above problems. The specific technical solution is as follows:
[0005] A material lifting mechanism with a feeding trolley comprises a frame, the frame is rotatably connected to a support rod, the outer surface of the support rod is connected to a gear, the outer surface of the gear is meshed with a conveying chain, the outer surface of the conveying chain is connected to a transmission block, the interior of the transmission block is rotatably connected to a support shaft one, one end of the support shaft one is connected to a connecting shell, the interior of the connecting shell is connected to a limiting rod, the outer surface of the limiting rod is rotatably connected to a charging hopper, the bottom surface of the charging hopper is connected to a connecting plate, the bottom surface of the frame is connected to a limiting block, and the bottom surface of the limiting block is installed with a cylinder.
[0006] Preferably, a support frame is connected to the interior of the frame, and a worm gear reducer is installed on the outer surface of the support frame.
[0007] Preferably, the worm gear reducer is mounted on the outer surface of the support rod, and a motor is mounted on the outer surface of the worm gear reducer.
[0008] Preferably, a limiting groove is provided inside the frame, an inner side wall of the limiting groove is slidably connected to an outer surface of the transmission block, and a limiting plate is connected to the outer surface of the frame.

[0011] Preferably, the output end of the cylinder is connected with a buckle, and the interior of the buckle is rotatably connected to the outer surface of the cross bar.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The material lifting mechanism of the feeding trolley cooperates with the conveyor chain, the connecting plate and other components. First, the conveyor chain can be moved. When the charging hopper needs to be moved, the user can move the charging hopper by moving the conveyor chain, so as to lift and lower the charging hopper. The connecting plate can be moved. When the connecting plate moves, the position of the charging hopper can be adjusted so that the charging can be adjusted to the appropriate position, thereby facilitating the unloading of the charging hopper and making the unloading position more accurate. It is very convenient and solves the problem of inconvenience in using material hoists with manual handling and chain hoists as power sources.
[0014] 2. The material lifting mechanism of the feeding trolley cooperates with the support frame, the limit plate and other components. The support frame provides support for the worm gear reducer, so that the worm gear reducer will not move arbitrarily when transmitting the power of the motor. The limit plate can limit the position of the support shaft 2, so that when the connecting shell moves to the position where it needs to turn, the support shaft 2 will not detach from the frame, which is very easy to use.

DETAILED DESCRIPTION
[0021] The present invention will now be further described with reference to the accompanying drawings.
[0022] See also Figure 1 , including a frame 1, the rotation of the frame 1 is connected to a support rod 2, the outer surface of the support rod 2 is connected to a gear 3, the frame 1 will limit the position of the support rod 2, so that the support rod 2 will not produce large vibrations when rotating, the support rod 2 will fix the position of the gear 3, and when the support rod 2 rotates, it will rotate with the gear 3
[0023] The outer surface of the gear 3 is engaged with the conveyor chain 4, and the outer surface of the conveyor chain 4 is connected to the transmission block 5. When the gear 3 rotates, it will move with the conveyor chain 4. When the conveyor chain 4 moves, it will rotate the gear 3 at the other end. The rotation of the gear 3 at the other end will rotate with the other support rod 2. The conveyor chain 4 will fix the position of the transmission block 5, and will move with the transmission block 5 when the conveyor chain 4 moves.
[0024] The internal rotation of the transmission block 5 is connected to the support shaft 6, and one end of the support shaft 6 is connected to the connecting shell 7. The transmission block 5 will limit the position of the support shaft 6. When the transmission block 5 moves, it will carry the support shaft 6. The support shaft 6 will fix the position of the connecting shell 7. When the support shaft 6 moves, it will carry the connecting shell 7 to move, thereby completing the pulling of the connecting shell 7.
[0025] The interior of the connecting shell 7 is connected to a limit rod 8, and the outer surface of the limit rod 8 is rotatably connected to a charging hopper 9. The connecting shell 7 will limit the position of the limit rod 8, and when the connecting shell 7 moves, it will move with the limit rod 8. The limit rod 8 can provide support for the charging hopper 9, allowing the charging hopper 9 to rotate around the limit rod 8, and when the limit rod 8 moves, it will move with the charging hopper 9.
[0026] The bottom surface of the charging hopper 9 is connected to a connecting plate 10, and the bottom surface of the frame 1 is connected to a limiting block 11. The bottom surface of the limiting block 11 is installed with a cylinder 12. The charging hopper 9 will fix the position of the connecting plate 10. When the connecting plate 10 moves, it will move with the charging hopper 9, and the movement of the connecting plate 10 will push the charging hopper 9 to the set material dropping position.
[0027] The interior of the frame 1 is connected to a support frame 13, and a worm gear reducer 14 is installed on the outer surface of the support frame 13. The frame 1 will fix the position of the support frame 13 so that the support frame 13 cannot move. The frames 1 at both ends are connected through the support frame 13 to increase the stability of the frame 1. The support frame 13 will limit the position of the worm gear reducer 14 so that the worm gear reducer 14 cannot move.
[0028] A worm gear reducer 14 is mounted on the outer surface of the support rod 2. A motor 15 is mounted on the outer surface of the worm gear reducer 14. The worm gear reducer 14 limits the position of the motor 15 and controls the force transmitted by the motor 15. This force is transmitted to the support rod 2 by the worm gear reducer 14, allowing the support rod 2 to rotate.
[0029] A limit slot 16 is formed inside the frame 1. The inner sidewall of the limit slot 16 is slidably connected to the outer surface of the transmission block 5. A limit plate 17 is connected to the outer surface of the frame 1. The inner sidewall of the limit slot 16 is relatively smooth, so other objects experience less friction when moving on the inner sidewall of the limit slot 16. The limit slot 16 limits the position where the transmission block 5 can move, thereby preventing the position of the transmission block 5 from deviating. The frame 1 will fix the position of the limit plate 17, preventing it from moving. A groove is formed between the limit plate 17 and the frame 1.
[0030] The outer surface of the connecting shell 7 is connected to the support shaft 2 18, and the outer surface of the support shaft 2 18 is slidably connected to the outer surface of the frame 1. The connecting shell 7 will fix the position of the support shaft 2 18, so that the support shaft 2 18 cannot move, and the frame 1 will limit the position to which the support shaft 2 18 can move. During the lifting process, when the charging hopper 9 is located in the lower half, the width of the limiting groove 16 is slightly larger than the diameter of the support rod 2, thereby limiting the shaking of the charging hopper 9 and offsetting the production error. At this time, the charging hopper 9 is close to the outer shell of the frame 1 under the action of gravity, which plays a limiting role for the charging hopper 9. When the charging hopper 9 is lifted to a certain height and needs to perform circular motion, the limiting plate 17 will limit the movable trajectory of the support shaft 2 18 to prevent the charging hopper 9 from running to a certain position and the hopper overturning under the action of gravity due to excessive impact force, causing damage to the conveyor chain 4.
[0031] The outer surface of the charging hopper 9 is rotatably connected to the inside of the connecting shell 7. The inside of the connecting plate 10 is connected to a cross bar 19. The connecting shell 7 will limit the position of the charging hopper 9, so that the charging hopper 9 cannot move at will. The connecting plate 10 will fix the position of the cross bar 19 and will move with the connecting plate 10 when the cross bar 19 moves.
[0032] The output end of the cylinder 12 is connected to a buckle 20, and the inside of the buckle 20 is rotatably connected to the outer surface of the cross bar 19. The cylinder 12 will fix the position of the buckle 20, and when the cylinder 12 moves, it will move with the buckle 20, and the cross bar 19 will move through the movement of the buckle 20, so that the cylinder 12 moves with the connecting plate 10. Before the loading hopper 9 moves, the cylinder 12 will push the feeding trolley to the set material drop position.
[0033] The cylinder 12, worm gear reducer 14, motor 15 and charging hopper 9 in this application are common electrical equipment in the prior art. This application will not go into too much detail about their models or internal structures, and they can also be replaced by other power sources.
[0034] When the utility model is in use: when using the device, first start the motor 15. The start of the motor 15 will cause the worm gear reducer 14 to rotate with the support rod 2. The rotation of the support rod 2 will cause the gear 3 to move with the conveyor chain 4. The movement of the conveyor chain 4 will cause the transmission block 5 to move with the support shaft 6. The support shaft 6 will move with the connecting shell 7. The movement of the connecting shell 7 will cause the limit rod 8 to move with the charging hopper 9, thereby causing the charging hopper 9 to rise. When unloading is required, the user needs to start the cylinder 12 to move the charging hopper 9 to the appropriate position, and then open the charging hopper 9 for unloading.
