Description

Technical Field

[0001] The present application relates to the technical field of graded crushed stone feeding, and in particular to a feeding device for graded crushed stone production. Background Art

[0002] Graded crushed stone is a mixture of aggregates of various sizes and particle sizes. When its gradation meets the requirements of technical specifications, it is called graded aggregate. Graded aggregate includes graded crushed stone, graded crushed gravel (a mixture of crushed stone and gravel, and often the oversized particles in gravel are crushed and combined with gravel to form crushed gravel) and graded gravel (or graded gravel);

[0003] The graded crushed stone is generally composed of crushed stones that are pre-screened into several (such as four) different sizes. After the crushed stones of different sizes are screened, they need to be mixed according to the proportion of different particles according to the needs. The different particle sizes need to be transported to the mixing device through the feeding device, and finally the graded crushed stone mixture of the required proportion is formed under the action of the mixing device.

[0004] With respect to the above-mentioned related technologies, the inventor believes that in order to ensure the coordination effect between the feeding device and the mixing device, the conveyor belt on the conveying device needs to be extended to the top of the feeding device to ensure that the crushed stones are located in the hopper of the mixing device after falling. The existing conveyor belt is always in an extended state, and the center of gravity is unstable during handling and transportation, which is easy to tip over and cause damage to the conveyor belt part. In addition, the space occupied by the conveyor belt in the extended state is relatively large. At the same time, when there are more crushed stones in the hopper, the conveyor belt located directly below the hopper will be subjected to greater pressure, increasing the load.

[0005] In order to solve the above problems, the present application proposes a feeding device for graded crushed stone production. Utility Model Content

A driving motor 5 for simultaneously driving the telescopic component 2 and the lifting component 3 is provided on the linkage component 4. A load-bearing component 7 for supporting stones is fixedly provided inside the hopper 11. The load-bearing component 7 reduces the pressure of the stones in the hopper 11 on the conveyor belt 16.

[0025] Reference Figure 4 The telescopic component 2 includes an internal threaded sleeve 21 fixed on the movable seat 15 and a telescopic screw 22 rotatably arranged in the fixed plate 13. A slot for the internal threaded sleeve 21 to move is opened on the fixed plate 13. The telescopic screw 22 is threadedly connected to the internal threaded sleeve 21. The internal threaded sleeve 21 and the telescopic screw 22 are two symmetrical groups, wherein a telescopic synchronization component 25 is provided between the two telescopic screws 22. A telescopic rod 26 is hingedly provided between the hopper 11 and the movable seat 15. The telescopic component 2 drives the conveyor belt 16 to adjust the extension length on the feeding device 1. The center of gravity of the feeding device 1 is more stable in the storage state, and the conveyor belt part is located on the inner side of the bracket 12 to play a protective role. The telescopic rod 26 has a structural reinforcement effect to ensure the reliability of the conveyor belt 16 when it is deployed.

[0026] Reference Figure 4 The telescopic component 2 also includes a sliding rod 23 fixed on the movable seat 15 and a sliding groove 24 opened inside the fixed plate 13 and slidingly matched with the sliding rod 23.

The lifting component 3 is linked with the telescopic component 2 to ensure the limiting position of the conveyor belt 16 in the storage state to prevent the conveyor belt 16 from automatically falling off due to the proximity of the fixed seat 14 and the movable seat 15.

[0028] Reference Figure 5 A guide rod 35 is provided between the fixed plate 13 and the support seat 31, a sliding groove cooperating with the guide rod 35 is provided on the lifting seat 32, the lifting screw 34 is threadedly connected to the internal thread block 33 and is two symmetrical groups, and a lifting synchronization component 36 is provided between the two lifting screws 34.

The gearbox 6 is connected to the telescopic synchronization component 25. The driving motor 5 directly drives the lifting component 3, and at the same time drives the telescopic component 2 under the action of the gearbox 6 to ensure the coordination between the telescopic component 2 and the lifting component 3, so as to avoid the conveyor belt 16 falling off the rotating roller during the adjustment process.

[0030] Reference Figure 6 The load-bearing component 7 includes a multi-layered load-bearing frame 71 and a fixing foot 72 for fixing the load-bearing frame 71 in the hopper 11. The load-bearing frame 71 is multi-layered and has mesh holes larger than the diameter of the crushed stone particles formed therein. When the stone material passes through the load-bearing component 7, the load-bearing component 7 can transfer the gravity located in the middle position of the hopper 11 to the hopper 11, thereby reducing the load on the conveyor belt 16 caused by the gravity of the stone material in the hopper 11.

[0031] Working principle: Stones are put into the hopper 11 through the loader, and the stones are not over the load-bearing component 7. The load-bearing component 7 transfers the gravity of the stones not over the load-bearing component 7 to the hopper 11, and the motor on one side of the fixed seat 14 is started to drive the conveyor belt 16 to rotate on the rotating rollers on the fixed seat 14 and the movable seat 15, and the conveyor belt 16 transports the stones dropped from the hopper 11 to the mixing device;

[0032] The extension of the conveyor belt 16 on the feeding device 1: after the drive motor 5 is started, the drive motor 5 directly drives the lifting synchronization component 36 through the linkage component 4, and then the linkage component 4 also drives the telescopic synchronization component 25 under the action of the gearbox 6, and the lifting synchronization component 36 drives the lifting screws 34 at both ends to rotate synchronously, and the internal thread block 33 drives the lifting seat 32 to move upward through the spiral of the lifting screw 34, and the rotating roller on the lifting seat 32 moves upward accordingly, and the telescopic synchronization component 25 drives the telescopic screws 22 at both ends to rotate synchronously, and the internal thread sleeve 21 drives the movable seat 15 to move toward the end away from the fixed plate 13 through the spiral of the telescopic screw 22, and the sliding rod 23 follows to extend in the sliding groove 24, and the telescopic rod 26 follows to extend. When the conveyor belt 16 is fully extended between the fixed seat 14 and the movable seat 15, the telescopic rod 26 is in the maximum extension state, and the drive motor 5 stops working, and the rotating roller on the lifting seat 32 is located in the conveyor belt 16, and the conveyor belt 16 is parallel up and down;

[0033] The conveyor belt 16 is stored in the upper feeding device 1: the driving motor 5 is turned on in reverse, and the driving motor 5 drives the movable seat 15 to retract into the upper feeding device 1 through the telescopic component 2. The driving motor 5 drives the lifting seat 32 to move downward through the lifting component 3, and the telescopic rod 26 shrinks accordingly.
