Stacking and taking operation baffle capable of preventing coal from spilling and leaking

Abstract

The utility model belongs to the field of conveyor devices, and particularly relates to a piling and taking operation baffle capable of preventing coal from spilling and leaking. Two push rods are rotationally installed on the lower surface of a material sliding plate, the telescopic ends of the push rods are rotationally installed on the lower surface of the baffle, the air inlet ends and the air outlet ends of the two push rods are each provided with a tee joint, and a rotating rod is rotationally installed on the lower surface of the material sliding plate; an elastic piece making contact with the conveying belt is installed at the end of the baffle. The telescopic ends of the two push rods are rotationally connected with the baffle, so that the two ends of the baffle are evenly stressed, and the problem that the ends of the baffle are prone to being stressed and deformed to cause material leakage due to the fact that the baffle only adopts middle supporting is solved. The air inlet ends and the air outlet ends of the two push rods are each provided with a tee joint, and therefore an external air source can conveniently control the two push rods to stretch out and draw back at the same time. And the stress uniformity of the baffles is improved, so that elastic pieces at the ends of the baffles can be tightly attached to the surface of the conveying belt conveniently, and the baffles can block materials on the conveying belt. Similarly, during stacking operation, the baffle is in an open state.

Description

Technical Field

[0001] This utility model belongs to the field of conveyor devices, specifically relating to a stacking and reclaiming baffle to prevent coal spillage. Background Technology

[0002] Stacker-reclaimers are widely used equipment in various production processes, primarily for retrieving materials from a stockpile and loading them onto a conveyor belt, or unloading materials back into a stockpile. They play a vital role in many industries, especially in ports, metallurgy, and mining. When a stacker-reclaimer is retrieving materials, the front baffle is closed to prevent spillage; when unloading, the front baffle is opened, and the material exits from the front.

[0003] However, existing material handling baffles often use a single cylinder to drive the material in the middle. This central drive can easily cause material to spill from both sides of the baffle, resulting in material waste and environmental pollution. In addition, using metal baffles that are in direct contact with the conveyor belt can easily cause damage to the conveyor belt due to metal friction. On the other hand, using rubber baffles can easily cause material spillage due to insufficient baffle hardness. Utility Model Content

[0004] This utility model addresses the shortcomings of existing equipment by providing a coal spillage prevention baffle for stacking and reclaiming operations. The specific technical solution is as follows:

[0005] A stacker-reclaimer operating baffle for preventing coal spillage includes a sliding plate and a baffle plate disposed at the lower end of the sliding plate. Two push rods are rotatably mounted on the lower surface of the sliding plate, and the telescopic ends of the push rods are rotatably mounted on the lower surface of the baffle plate. Both the air inlet and outlet ends of the two push rods are provided with tees. Two parallel rotating rods are fixed on the lower surface of the baffle plate, and the rotating rods are rotatably mounted on the lower surface of the sliding plate. An elastic element that contacts the conveyor belt is installed at the end of the baffle plate.

[0006] The elastic element includes an elastic rubber strip at the end of the baffle, a limit strip integrally formed on the side of the elastic rubber strip, a limit groove opened at the end of the baffle, and the limit strip installed inside the limit groove. End plates are provided on both sides of the baffle, and positioning bolts are screwed into screw holes on the side surface of the baffle and the end plates.

[0007] The end plate consists of two vertical rectangular plates.

[0008] The limiting strip is composed of a cylinder and a rectangular plate, and the limiting strip and the limiting slot are compatible.

[0009] The lower surface of the baffle is integrally formed with a support plate, and the elastic rubber strip is in contact with the upper surface of the support plate.

[0010] The upper surface of the sliding plate is integrally formed with a joint plate, and the joint plate is in contact with the upper surface of the baffle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Two push rods are rotatably mounted on the lower surface of the material sliding plate. The telescopic ends of both push rods are rotatably connected to the baffle, allowing the two push rods to work together to rotate the baffle. This ensures even force distribution at both ends of the baffle, preventing material leakage caused by end deformation due to only central support. Both push rods have tees at their air inlet and outlet ends, facilitating simultaneous extension and retraction of the two push rods by an external air source. This further increases the evenness of force distribution on the baffle, ensuring the elastic elements at the baffle ends fit snugly against the conveyor belt surface, effectively blocking material on the conveyor belt. Similarly, the baffle is in the open position during stacking operations.

[0013] 2. An elastic element consisting of an elastic rubber strip, a limiting strip, a limiting groove, an end plate, and positioning bolts is used. The limiting strip, integrally formed on the side surface of the elastic rubber strip, is installed in the limiting groove at the end of the baffle, which facilitates the installation of the elastic rubber strip at the end of the baffle. At the same time, the end plates on both sides of the baffle are positioned by positioning bolts, which facilitates the two end plates to block the elastic rubber strip from the side, increasing the stability of the elastic rubber strip installed at the end of the baffle.

[0019] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1-4This embodiment provides the following technical solution: a coal spillage prevention stacking operation baffle, including a sliding plate 1 and a baffle 2 set at the lower end of the sliding plate 1. Two push rods 3 are rotatably installed on the lower surface of the sliding plate 1. The telescopic ends of the push rods 3 are rotatably installed on the lower surface of the baffle 2. Both the air inlet and outlet ends of the two push rods 3 are provided with tees 4. Two parallel rotating rods 5 are fixed on the lower surface of the baffle 2, and the rotating rods 5 are rotatably installed on the lower surface of the sliding plate 1. An elastic element that contacts the conveyor belt is installed at the end of the baffle 2.

[0021] In this embodiment, two push rods 3 are rotatably mounted on the lower surface of the sliding plate 1, and the telescopic ends of the two push rods 3 are rotatably connected to the baffle 2. This facilitates the joint action of the two push rods 3 to rotate the baffle 2, making the force on both ends of the baffle 2 uniform. This prevents the baffle 2 from being easily deformed at the ends due to force and leakage if only the middle support is used. Both the air inlet and outlet ends of the two push rods 3 are provided with tees 4, which facilitates the simultaneous extension and retraction of the two push rods 3 by an external air source. This increases the uniformity of the force on the baffle 2, making it easier for the elastic element at the end of the baffle 2 to fit tightly against the surface of the conveyor belt, so that the baffle 2 can block the material on the conveyor belt.

[0022] In this embodiment, the elastic element includes an elastic rubber strip 7 provided at the end of the baffle 2, a limiting strip 8 integrally formed on the side of the elastic rubber strip 7, a limiting groove 9 provided at the end of the baffle 2, and the limiting strip 8 installed inside the limiting groove 9. End plates 11 are provided on both sides of the baffle 2, and positioning bolts 12 are screwed into screw holes on the side surface of the baffle 2 and the end plates 11. The end plates 11 are composed of two vertical rectangular plates, and the limiting strip 8 is composed of a cylinder and a rectangular plate, and the limiting strip 8 and the limiting groove 9 are adapted to each other.

[0023] In this embodiment, an elastic element consisting of an elastic rubber strip 7, a limiting strip 8, a limiting groove 9, an end plate 11, and a positioning bolt 12 is used. The limiting strip 8, which is integrally formed on the side surface of the elastic rubber strip 7, is installed in the limiting groove 9 opened at the end of the baffle 2, which facilitates the installation of the elastic rubber strip 7 at the end of the baffle 2. At the same time, the end plates 11 provided on both sides of the baffle 2 are positioned by the positioning bolt 12, which facilitates the two end plates 11 to block the elastic rubber strip 7 from the side, thereby increasing the stability of the elastic rubber strip 7 installed at the end of the baffle 2.

[0024] In this embodiment, the lower surface of the baffle 2 is integrally formed with a support plate 10, and the elastic rubber strip 7 is in contact with the upper surface of the support plate 10, so that the support plate 10 can support the elastic rubber strip 7.

[0025] In this embodiment, the upper surface of the sliding plate 1 is integrally formed with a connector plate 6, and the connector plate 6 is in contact with the upper surface of the baffle 2, so that the connector plate 6 can cover the joint between the sliding plate 1 and the baffle 2.
