Description

Technical Field

[0001] This utility model belongs to the field of material feeding chute technology, specifically relating to a material feeding buffer chute for a limestone crusher. Background Technology

[0002] Belt conveyors are widely used in the aggregate mining industry due to their advantages of large transport capacity, high efficiency, and low cost. In actual use, belt conveyors typically discharge at the head and load at the tail, with a feed chute connecting to the loading point to achieve continuous material transport. Large-drop feed chutes are generally designed as long, vertical sections for unloading, or have a buffer plate at the front end for cushioning. However, actual production experience shows that this type of process is not suitable for conveying ore in the aggregate mining industry. Large, angular, and hard ore particles will impact the belt conveyor, continuously denting the belt surface and severely affecting its service life. Utility Model Content

[0024] The chute body includes a left stepped baffle plate 3, a right stepped baffle plate 4, a front stiffener baffle plate 5, a rear stiffener baffle plate 6, and a central flat baffle plate 7. The left ends of the front stiffener baffle plate 5 and the rear stiffener baffle plate 6 are fixedly connected to the front and rear edges of the left stepped baffle plate 3, respectively. The right ends of the front stiffener baffle plate 5 and the rear stiffener baffle plate 6 are fixedly connected to the front and rear edges of the right stepped baffle plate 4, respectively. The central flat baffle plate 7 is located between the left stepped baffle plate 3, the right stepped baffle plate 4, the front stiffener baffle plate 5, the rear stiffener baffle plate 6, and the central flat baffle plate 7.

[0025] The left step baffle plate 3 and the right step baffle plate 4 are symmetrically arranged, and both extend horizontally in the front-to-back direction. The left step baffle plate 3 and the right step baffle plate 4 include multiple steps of the same size, and their lower ends are close to each other.

[0026] The front and rear stiffener baffle plates 5 and 6 are symmetrically arranged, extending horizontally in both directions. Each baffle plate includes an upper baffle plate 8 and a lower baffle plate 9. The lower edge of the upper baffle plate 8 is fixedly connected to the upper edge of the lower baffle plate 9. The angle between the upper baffle plate 8 and the vertical plane in the front-rear direction is greater than the angle between the lower baffle plate 9 and the vertical plane in the front-rear direction. A row of stiffeners 10 is fixedly arranged on the end faces of the two upper baffle plates 8 that are close to each other. The row of stiffeners 10 extends horizontally in both directions and is perpendicular to the upper baffle plates 8. A row of reinforcing ribs 10 is fixedly provided on the side end face of the two lower baffle plates 9 that are close to each other. The row of reinforcing ribs 10 is arranged in the vertical direction and extends in the horizontal direction. The reinforcing ribs 10 are perpendicular to the lower baffle plates 9.

[0027] The central flat baffle plate 7 is a horizontally arranged square plate structure. The front and rear ends of the central flat baffle plate 7 are fixedly connected to the upper baffle plate 8 of the front stiffener baffle plate 5 and the upper baffle plate 8 of the rear stiffener baffle plate 6, respectively.

[0031] The height difference between each step of the left step baffle 3 and the right step baffle 4 is 200mm.

[0032] The height difference between the stiffeners 10 on the front stiffener baffle 5 and the rear stiffener baffle 6 is 200mm.

[0033] The working principle of this utility model is as follows:

[0034] After the limestone crusher 1 crushes the material, the crushed material enters the chute body through the upper opening. The material first impacts the central flat baffle 7, forming an initial buffer. Then, all the material passes through both sides of the central flat baffle 7, achieving diversion. The diverted material falls onto the second-stage left-side stepped baffle 3, right-side stepped baffle 4, front-side stiffened baffle 5, and rear-side stiffened baffle 6, further buffering the material. When the material accumulates to a certain extent on the second-stage left-side stepped baffle 3, right-side stepped baffle 4, front-side stiffened baffle 5, and rear-side stiffened baffle 6, it gradually converges towards the center and continues to fall to the discharge port baffle 12. It is then output from the discharge port 11 onto the belt conveyor 13, concentrating towards the centerline of the belt without spillage.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
