Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology, specifically a movable three-station reversible distribution belt conveyor. Background Technology

[0002] I. In coal mines with vertical shaft hoisting, the bottom of the main vertical shaft usually has 2 to 3 coal bunkers. The functions of the coal bunkers are as follows:

[0003] 1. Temporary storage of raw coal balances the contradiction between continuous production at the coal mining face and the intermittent operation of the skip hoist, ensuring that the underground transportation system can still operate normally when the skip is not discharging coal. The coal bunker, as a buffer hub, can eliminate the rhythm difference between the coal mining and transportation systems.

[0004] 2. The main shaft coal bunker is directly connected to the skip loading system, enabling rapid coal loading and supporting the efficient and continuous operation of the main shaft hoisting system.

[0005] 3. In the event of sudden equipment failure or transportation disruption in the mine, the coal bunker can provide emergency reserves, buy time for repairs, and reduce the risk of production stoppage.

[0006] Second, with coal bunkers in place, it is necessary to consider the imbalance in transportation matching, which can easily lead to an imbalance in storage between two (or three) coal bunkers. Therefore, it is necessary to add distribution equipment at the top of the coal bunkers.

[0007] Traditional silo distribution equipment includes silo belt conveyors and silo scraper conveyors. Due to their heavy weight, high noise, high energy consumption, and slow speed and low conveying capacity, silo scraper conveyors are being adopted less and less.

[0008] The commonly used distribution belt conveyor is a regular belt conveyor. By adding a branch chute at the material drop point, coal can be directly dropped into the bin or fed onto the distribution belt via the branch chute into another coal bin.

[0009] Disadvantages of this arrangement:

[0010] 1. The belt conveyor and the chute are set on opposite sides of the center of the silo. Coal falling can easily lead to insufficient silo capacity, and the uneven distribution of forces on the coal silo can easily cause accidents.

[0011] 2. The branching of the branching chute requires height, which necessitates raising the size of the upper chamber of the coal bunker, resulting in a larger and higher opening at the top of the coal bunker and making support difficult. Utility Model Content

[0012] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0013] Given the following technical problems in the existing technology: the existing branched coal chute requires increasing the overall height of the equipment, which increases the space occupied.

[0014] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a movable three-station reversible silo conveyor, comprising,

[0015] A guide rail frame and a retractable conveyor, wherein the retractable conveyor is mounted on the guide rail frame and is movable on the guide rail frame;

[0016] The telescopic conveyor is provided with a first guide chute at one end and a second guide chute at the other end.

[0017] As a preferred technical solution for a movable three-station reversible distribution belt conveyor, a first chute is provided on the outside of the first guide chute, and a second chute is provided on the outside of the second guide chute.

[0018] As a preferred technical solution for a mobile three-station reversible distribution belt conveyor, the telescopic conveyor includes a first frame and a second frame slidably connected to the first frame. A first roller is provided on the first frame, and a second roller is provided on the second frame.

[0019] As a preferred technical solution for a mobile three-station reversible distribution belt conveyor, a redirecting roller is also provided on the first hanger, and the belt is wound around the outside of the second roller, the first roller and the redirecting roller.

[0020] As a preferred technical solution for a movable three-station reversible distribution belt conveyor, an extension frame is provided on the first hanging frame, and the first guide chute and the first chute are provided on the extension frame.

[0021] As a preferred technical solution for a movable three-station reversible distribution belt conveyor, a first coal bunker and a second coal bunker are respectively arranged below both ends of the guide rail frame.

[0022] The beneficial effects of this utility model are: This utility model not only realizes that coal from both wings is dropped into the center of each bin, but also eliminates the need for branch chutes, reducing the height of the upper chamber of the coal bin, and the system is simple and highly operable.

[0036] Example 1

[0037] Reference Figures 1 to 7 This embodiment provides a movable three-station reversible silo belt conveyor, including a guide rail frame 100 and a telescopic conveyor 200. The telescopic conveyor 200 is movably mounted on the guide rail frame 100. One end of the telescopic conveyor 200 is provided with a first guide chute 201, and the other end of the telescopic conveyor 200 is provided with a second guide chute 202.

[0038] The first guide chute 201 and the second guide chute 202 are located on the outside of the telescopic conveyor 200, that is, on the outside of the head and tail of the telescopic conveyor 200. The first guide chute 201 and the second guide chute 202 extend downwards to the telescopic conveyor 200 to guide the material falling into the first guide chute 201 and the second guide chute 202 to the telescopic conveyor 200.

[0039] The extendable conveyor 200 is a belt conveyor that can transport goods in both forward and reverse directions.

[0040] The guide rail frame 100 is fixed in place, and the first coal bunker 301 and the second coal bunker 302 are located below both ends of the guide rail frame 100.

[0041] The telescopic conveyor 200 moves on the guide rail frame 100.

[0042] A first chute 203 is provided on the outer side of the first guide chute 201, and a second chute 204 is provided on the outer side of the second guide chute 202.

[0043] The first chute 203 is used to pour coal from the conveyor belt 207 or directly from the main roadway above the No. 1 bottom coal bunker into the first coal bunker 301. The second chute 204 is used to pour coal from the conveyor belt 207 or directly from the main roadway above the No. 2 bottom coal bunker into the second coal bunker 302.

[0044] The telescopic conveyor 200 includes a first bracket 205 and a second bracket 206 slidably connected to the first bracket 205. A first roller 205a is provided on the first bracket 205, and a second roller 206a is provided on the second bracket 206.

[0045] The first hanger 205 is also equipped with a redirecting roller 205b, and the belt 207 is wound around the outside of the second roller 206a, the first roller 205a and the redirecting roller 205b.

[0046] The second bracket 206 can be adjusted and slid relative to the first bracket 205. The redirecting roller 205b can be moved along the guide rail by motor control, thereby changing the effective working length of the belt. Specifically, the telescopic principle of the telescopic conveyor 200 is existing technology, and the control details will not be elaborated here.

[0047] The first hanger 205 and the second hanger 206 are equipped with traveling rollers, which are engaged with the guide rail frame 100 to facilitate the overall movement of the telescopic conveyor 200 on the guide rail frame 100.

[0048] An extension frame 205c is provided on the first hanging frame 205, and the first guide chute 201 and the first chute 203 are provided on the extension frame 205c.

[0049] When the telescopic conveyor 200 moves as a whole, it can move the first hanging frame 205, the first guide chute 201 and the first chute 203 set on it together.

[0050] Similarly, the second hanger 206 is also equipped with an extension frame that carries the second guide chute 202 and the second chute 204. The second guide chute 202 and the second chute 204 move in tandem with the second hanger 206.

[0051] The first coal bunker 301 and the second coal bunker 302 are respectively installed below both ends of the guide rail frame 100.

[0052] Specifically,

[0053] In this application, the extendable conveyor 200 is a reversible belt conveyor capable of operating in multiple states and traveling a distance of 3-5 meters. The extendable conveyor 200 has chutes at both its head and tail, which are fixed to the head and tail frames of the belt conveyor. It can move with the belt conveyor. When the first coal bunker 301 needs coal blending, coal from the main roadway can directly pass through the fixed chute at the tail. Figure 1 Material is discharged from the first chute 203 on the right side of the center. At this time, the telescopic conveyor 200 is not running. This is the first working position. (Refer to...) Figure 3 .

[0054] When the first coal bunker 301 is full and a full-bundle signal is issued, the belt conveyor moves towards the tail end (in the direction of the first coal bunker), connecting its first guide chute 201 with the chute of the main roadway coal conveyor. Coal from the main roadway enters the first guide chute 201 and falls onto the belt conveyor 207, then is transported to the second coal bunker 302. This is the second workstation. (Refer to...) Figure 5 ;

[0055] Similarly, coal coming from the main roadway above the second coal bunker 302 can also be distributed into the first coal bunker 301 through the same operation, as described above. Figure 4 .

[0056] The above two workstations represent situations where coal does not arrive at the two coal bunkers simultaneously. If coal arrives at the main roadway above both coal bunkers simultaneously, the redirecting roller 205b is used to reduce the effective working length of the entire telescopic conveyor 200 belt. This allows the first chute 203 and the second chute 204 to connect with the corresponding chutes of the main roadway belt conveyor above the coal bunkers, achieving direct filling. This is the third workstation, see reference. Figure 2 .

[0057] This utility model only requires setting three station limit and anchoring devices on the guide rail frame, setting material guide chutes at both the head and tail of the machine, setting chutes at the head and tail of the machine that are fixed and movable with the head frame and tail frame, and adding a telescopic head.

[0058] This equipment not only enables coal from both wings to be discharged into the center of the bunker, but also eliminates the need for branch chutes, reducing the height of the upper chamber of the coal bunker. Furthermore, the system is simple, highly operable, and can be expanded to include sensors installed at the coal bunker locations and three-position sensors, thus achieving unmanned operation.

[0059] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
