With the demand of the limestone market, the demand for different particle grades is high, so the block ore rate can only be increased from the mining process, but the generated block has increased than in the past. The underground coarse crushing is set at the bottom of the high and deep ore pass, and the ore is sent to the crusher by the heavy duty apron feeder. As the first gate for pulling ore, there is often a phenomenon of large blocks blocking the feed port of the heavy duty apron feeder. Due to space restrictions, personnel directly enter the feed port of the heavy duty apron feeder to deal with the mine blocking safety risk, and the feed port is smooth around. Personnel are not easy to find the fulcrum to use tools such as crowbars for processing: if the blasting method is used, it is easy to destroy the equipment, seriously restricting the completion of the production task.
1. In order to overcome the problems existing in the prior art, the utility model aims to provide a ore-blocking treatment tool for the feed port of a high and deep chute, which has fast ore-blocking speed and high safety factor, and solves the problems existing in the prior art. The technical solutions adopted are:
2. The utility model relates to a high and deep chore feed port blocking ore treatment tool, comprising a supporting lug, which is arranged with two supporting lugs, which are fixed connected to the end face of the feeder, rotating connected with a rotating shaft on the supporting lug, two supporting lugs are arranged at both ends of the rotating shaft, and the rotating shaft is fixed connected with a crowbar, which is vertically arranged with the rotating shaft. The crowbar extends the direction of the feeder. The crowbar is connected with a pull rope, and the pull rope extends to the outside of the feeder feed port. The support lug is used to form a fixed support point, the pull rope controls the support Angle of the crowbar, and the crowbar relies on the feeder to provide force to loosen the blocked ore, thus dealing with the blockage of the feed port.
3. The crowbar is further arranged with a blind hole at the top, and the blind hole is inserted with an extension bar, which can be replaced by an extension bar to adapt to the cleaning work under different states. 4. The utility model has the following advantages:
(1) The structure is simple, and the use of simple mechanical structure can replace manual cleaning of feed port blockage:
(2). No need for personnel to enter the feed port to ensure personnel safety:
(3) There is no need to take blasting methods to prevent damage to equipment and facilities:
4. Easy to use, improve production efficiency.
Specific implementation method:
Comprises support lug 1, support lug 1 is arranged with two, support lug 1 is fixed connected on apron feeder end face, support lug 1 is rotated connected with a rotating shaft 2, two support lug 1 is arranged on both ends of the rotating shaft 2, the rotating shaft 2 is fixed connected with a crowbar 3, the crowbar 3 is arranged vertically with the rotating shaft 2, the crowbar 3 extends the direction of the feeder is arranged, and the crowbar 3 is connected with a drawrope 4, the crowbar 3 is connected with the crowbar 3. The rope 4 is extended to the outside of the feed port of the feeder. When the feed port is blocked, the position of the blocked ore is observed from the outside of the feed port, and then the support lug 1 of the utility model is fixed on the end face of the feeder by welding. At this time, the crowbar 3 should be aligned with the position of the ore lever, and then the feeder is turned over, so that the utility model enters the inside of the feed port in the reverse direction. Pull up the crowbar 3 by pulling the rope 4, so that the crowbar 3 and the feeder form a certain Angle, until the crowbar 3 top reaches the position of the ore material and the rope 4 is released when the effort is made, and then the crowbar 3 is driven by the feeder to continue to move in the direction of the ore material, the crowbar 3 relies on the feeder as the power source, and the rotating shaft 2 is the fulcrum to form a leverage effect. Then pry the ore loose or break the ore directly, so as to achieve the purpose of dredging the feed port. After dredging, the ore is transported out of the feed port, and then the utility model is carried to the outside of the feed port for dismantling through the feeder. The blind hole 5 is arranged at the top of the crow bar 3, and the blind hole 5 is inserted with an extension bar 6. Due to the different size and shape of the ore, the extension bar 6 can be selected according to the actual situation, and multiple extension bars 6 can be set and each length is different to ensure the normal cleaning work of the feed port blockage. When used, the ore material is just stuck above the feed port. At this time, an extension bar 6 of appropriate length is selected according to the condition of the ore material and connected to the crowbar 3, and then the utility model is fixed on the end face of the feeder, and then the utility model enters the inside of the feed port in the reverse direction through the apron feeder, and pulls up the crowbar 3 through the pulling rope 4. When the extension rod 6 tells the lower side of the ore material, loosen the rope 4 and use the power of the feeder to complete the cleaning work of the feed port blockage.
