Description

Technical Field

[0001] The invention relates to the technical field of sandstone processing system engineering production, and in particular to a material receiving buffer frame device for preventing a belt conveyor belt from being penetrated. Background Art

[0002] In the sand and gravel processing system project, the crushing production in the coarse crushing workshop is the first crushing process. The particle size of the semi-finished aggregate after crushing by this process is about 250mm. Because there are many special-shaped raw materials in the blasting raw materials, it is inevitable to produce flaky or partially sharp raw materials in the coarse crushing production process. During the falling process, the sharp part of the raw materials is just facing the conveying belt conveyor, causing the sharp part to directly penetrate the conveyor belt. Because the belt conveyor is in operation, the raw material penetration will cause the conveyor belt to be partially or completely divided into two halves. It is necessary to stop the machine to clean the falling materials and replace the conveyor belt of the belt conveyor. Replacing the conveyor belt will inevitably lead to interruption of aggregate transportation and reduce production efficiency. In order to increase the service life of the conveyor belt, further improve the production efficiency of the coarse crushing workshop of the sand and gravel system, and reduce operating costs, it is necessary to provide a material receiving buffer rack device to solve such problems and create a safer and more economical environment for the operation of the sand and gravel processing system.

DETAILED DESCRIPTION

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

[0021] like Figure 1 As shown in FIG. 3 , the present invention is a material receiving buffer frame device for preventing the belt of a belt conveyor from being penetrated. The material receiving buffer frame device is arranged between the steel trusses 1 of the belt conveyor, below the belt of the belt conveyor, and at the material receiving place of the belt conveyor at the material discharge port 2 of the crusher. The material receiving buffer frame device includes a buffer roller assembly 3, a steel frame 4 and a buffer 5.

[0022] The steel frame 4 is composed of an upper steel frame 6 and a lower steel frame 7. The upper steel frame 6 is welded into two rectangular frames by transverse channel steels and connected into an integral upper steel frame 6 by vertical channel steels. The lower steel frame 7 is welded into a rectangular frame by transverse channel steels. The upper steel frame 6 and the lower steel frame 7 are connected by buffers 5. The lower steel frame 7 is fixedly connected to the steel trusses 1 of the belt conveyor on both sides. The buffer roller assembly 3 is arranged on the upper steel frame 6. The buffer roller assembly 3 is composed of a plurality of main rollers 8 and roller brackets 9. The plurality of main rollers 8 are arranged on the upper steel frame 6 in parallel and horizontally rotatable manner by roller brackets 9. The roller brackets 9 are fixedly connected to the upper steel frame 6. The mutual spacing between the main rollers 8 is smaller than the grain size of the raw material, preferably 200 mm, so that the impact force of the raw material can be completely transmitted to the main rollers 8.

[0023] The irregular raw material first contacts the main roller 8 during the blanking process. Since the main roller 8 can rotate horizontally, the impact force of the raw material is dispersed to both sides, and the impact force is transmitted to the upper steel frame 6 and the lower steel frame 7 in turn through the main roller 8. Since the upper steel frame 6 and the lower steel frame 7 are connected by the buffer 5, the impact force of the raw material can be absorbed and reduced by the buffer 5 for a second time. The buffer 5 can be replaced with a buffer spring or a polyurethane buffer block or other similar products.

[0024] After the special-shaped raw material contacts the main roller 8, it is bound to cause the material receiving buffer frame device to shake back and forth. In order to avoid this phenomenon, the material receiving buffer frame device is also provided with a guide wheel assembly 10 and a rail 11. The guide wheel assembly 10 and the rail 11 are arranged at the four corners of the upper steel frame 6, and are located between the upper steel frame 6 and the belt conveyor steel truss 1. The guide wheel assembly 10 is composed of a guide wheel channel steel 12 and a guide wheel 13. The guide wheel channel steel 12 is fixedly connected to the two rectangular frames of the upper steel frame 6. The upper end of the guide wheel channel steel 12 is located in the same horizontal plane as the upper steel frame 6. A rotatable guide wheel 13 is provided in the groove of the guide wheel channel steel 12. The diameter of the guide wheel 13 is smaller than the cross-sectional width of the guide wheel channel steel 12. One side of the rail 11 is fixedly connected to the belt conveyor steel truss 1, and the other side of the rail 11 can be inserted into the groove of the guide wheel channel steel 12 and abut against the guide wheel 13. The additional guide wheel 13 assembly 10 and the steel rail 11 can effectively avoid the shaking phenomenon of the material receiving buffer frame device after the special-shaped raw material contacts the main roller 8.

[0025] In order to allow the irregular raw material to move to the center of the receiving buffer rack device after being dropped, so as to facilitate the conveying of the belt conveyor, inclined auxiliary rollers 14 can be added on both sides of the main roller 8, and the angle between the auxiliary roller 14 and the main roller 8 is preferably 30°. The auxiliary roller 14 is rotatably arranged on the auxiliary bracket 15, and the auxiliary bracket 15 is fixedly connected to the roller bracket 9. This design allows the irregular raw material to move to the center of the receiving buffer rack device after being dropped, and will not slip or the like.

[0026] In addition, the main roller 8 and the auxiliary roller 14 can be unpowered rollers or electric rollers. The unpowered rollers can be driven by the belt of the belt conveyor. If the material receiving buffer frame device is arranged in the middle of the steel truss 1 of the belt conveyor, electric rollers can also be used.
