Description

Technical Field

[0001] The utility model belongs to the field of scrapers, and in particular relates to a scraper device for mines. Background Art

[0002] The scraper series products are widely used in metallurgy, building materials, electric power, chemical industry, cement, ports, docks, coal, mining, grain and oil, food, feed and other industries and departments. The scraper is a continuous transportation equipment that conveys bulk materials with the help of moving scraper chains in a closed rectangular cross-section shell. Because the scraper chains are completely buried in the materials when conveying materials, it is called a scraper.

[0003] During the loading process, after the material enters the shell from the hopper, the material ore is transported by the conveyor belt in conjunction with the scraper. Since there is a slight gap between the scraper and the bottom of the shell, it is easy to cause material accumulation. In order to ensure the conveying effect, it is necessary to clean it regularly. In addition, when the material falls from the hopper into the conveyor belt, it is easy to cause impact on the conveyor belt. In view of this, the present invention is specially proposed.

[0015] After adopting the above technical solutions, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0016] 1. The utility model is provided with a discharge support at the bottom of the scraper casing. Under normal working conditions, the discharge chute will be resisted by the support plate, so it will not affect the transportation of materials to the discharge port. When it is necessary to clean the accumulated material, the telescopic ends on both sides of the hydraulic cylinder are retracted so that the upper surface of the support plate is flush with the outlet chute. Then, in order to ensure the discharge effect, the telescopic end of the hydraulic cylinder on one side of the outlet chute can be controlled to extend so that the support plate is tilted. At this time, the accumulated material can be discharged through the outlet chute; secondly, considering that the material is likely to cause impact on the conveyor belt when falling from the hopper to the conveyor belt, the utility model designs a buffer top in the middle of the hopper. When the material is introduced into the hopper, it first impacts the buffer top. During the buffering, the buffer spring absorbs the impact force. In the process of releasing the elastic potential energy, it will be suppressed by the damping rod, thereby completing the buffering. Then, the material pops out of the buffer top to relieve the impact force and is discharged from the through hole to the inside of the scraper casing and is transported by the conveyor provided inside the scraper casing;

[0017] 2. The speed of discharging accumulated materials from the pallet is increased by setting a vibration plate on the top of the pallet. That is, a small vibration motor can be used to generate vibration, and the vibration plate generates vibration to accelerate the speed of the surface material out of the outlet chute. When discharging, it is necessary to start the switch of the electric telescopic column first so that the telescopic end support block of the electric telescopic column does not contact the bottom of the vibration plate, which is a reserved area for the vibration of the vibration plate.

[0018] The specific implementation of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] See also Figures 1 to 5 The utility model provides a technical solution: a scraper device for mining, comprising a scraper housing 1, a discharge support 11 and a buffer top 7.

A discharge port is provided at the upper end of the scraper housing 1. A hopper 4 is fixed to the upper end of the discharge port. A discharge port is provided on one side of the lower end of the scraper housing 1.

The top of the special-shaped block 6 is movably connected to a buffer top 7. A damping rod 8 is fixedly installed inside the special-shaped block 6. The telescopic end of the damping rod 8 is fixed to the inner top of the buffer top 7. The telescopic end of the damping rod 8 is externally sleeved with a buffer spring 9. A plurality of through holes 10 for feeding ore crushing materials are opened through the upper end of the support plate 5;

[0032] A discharge support 11 is fixed to the middle part of the lower end of the scraper casing 1, and a support plate 12 for sealing the discharge trough at the bottom of the scraper casing 1 is provided inside the discharge support 11. A hydraulic cylinder 13 is symmetrically fixed to the inside of the discharge support 11, and a shaft 14 is fixed to the telescopic end of the hydraulic cylinder 13. Slide sleeves 15 are provided on the outside of the front and rear ends of the shaft 14, and the slide is installed in the middle of the kit 16 at the bottom of the support plate 12. A guide groove 17 for discharging accumulated materials is provided on one side of the discharge support 11. Considering that during the feeding process, the material enters the casing from the hopper 4 and is transported by the conveyor belt in cooperation with the scraper, and there is a slight gap between the scraper and the bottom of the casing, which easily leads to material accumulation. In order to ensure the conveying effect, regular cleaning is required. The utility model provides a discharge support 11 at the bottom of the scraper casing 1. Under normal working conditions, the discharge trough will be blocked by the support plate 12. This will not affect the transportation of materials to the discharge port. When the accumulated material needs to be cleaned, the telescopic ends on both sides of the hydraulic cylinder 13 are retracted so that the upper surface of the support plate 12 is flush with the outlet groove 17. Then, in order to ensure the discharge effect, the telescopic end of the hydraulic cylinder 13 on one side of the outlet groove 17 can be controlled to extend, so that the support plate 12 is tilted.

The support block 25 is used to abut against the vibrating plate 21. By providing the vibrating plate 21 on the top of the support plate 12, the speed of the support plate 12 discharging the accumulated material is increased. That is, the small vibrating motor 22 can be used to generate vibration, and the vibrating plate 21 generates vibration to accelerate the speed of the accumulated material on the surface area being discharged into the discharge chute 17. When discharging, the switch of the electric telescopic column 24 needs to be started first, so that the support block 25 at the telescopic end of the electric telescopic column 24 does not contact the bottom of the vibrating plate 21, reserving an area for the vibration of the vibrating plate 21.

[0035] Among them, first wear-resistant sleeves 26 are fixedly installed on the outsides of the buffer top 7 and the special-shaped block 6, and a second wear-resistant sleeve 27 is fixedly installed on the inner wall of the hopper 4.
