Description

Technical Field

[0001] The utility model belongs to the technical field of underground mining machinery and equipment, and relates to a clamping plate mechanism for clamping iron waste in rocks. Background Art

[0002] In the process of metal mining, the transportation and crushing of ore are indispensable links. After the rock is mined, it is transported by loading equipment to the screen of the chute crushing station. In the crushing station, the breaker crushes the rock to a size suitable for screening. During the screening process, the undersize product falls through the screen and enters the chute system.

[0003] The mined rocks are usually mixed with waste anchor nets, anchor rods and other iron waste used in support operations. After the breaker hammer performs the rock crushing operation, the screen will accumulate iron waste mixed or interspersed in the rock. In order to prevent the iron waste from entering the chute system, these iron wastes need to be removed in time. If these iron wastes are not removed in time, they will cause damage to the system conveyor belt and other equipment, increasing maintenance costs.

[0004] At present, in the underground rock crushing operation of metal mines, the main means of removing and processing the iron waste accumulated on the screen is manual picking, that is, the operator steps on the screen to pick up the iron waste. This method has the following main problems: First, when the operator steps on the screen to pick up the iron waste, it is easy to slip, fall into the chute and other safety accidents. Second, the manual picking of iron waste is inefficient, which affects the progress of the crushing operation. Utility Model Content

[0010] Compared with the prior art, the utility model has the following beneficial effects.

[0011] First, the utility model installs a clamping assembly on a side different from the breaker, and uses a flip cylinder to push the telescopic breaker bracket to achieve the purpose of switching between the crushing and clamping positions. After the breaker breaks the rock, the piston rod of the flip cylinder is controlled to extend so that the drill rod of the breaker is parallel to the plane where the screen is located. At this time, the clamping assembly is in the working position. The clamping parts of the left and right clamps are closed and separated by controlling the two-way cylinder, thereby completing the clamping and removal operations of waste anchor nets, anchor rods and other iron waste on the screen. The two tasks of crushing and waste removal are completed on a set of hydraulic breaker, realizing two uses of one machine. Not only does it realize the mechanized operation of removing iron waste such as anchor nets and anchor rods during rock crushing, but it also saves the conversion time between different operations, further improving work efficiency.

[0012] Second, the clamping assembly of the utility model is installed on the left and right brackets of the breaker hammer through separate connecting plates at different side positions of the breaker hammer, so that the crushing and clamping do not interfere with each other.

[0013] Third, in the optimized technical solution of the utility model, reinforcing ribs are welded on the outer sides of the left bracket and the right bracket, respectively, which further improves the overall structural strength of the bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 1 and Figure 3 The hydraulic breaker of the utility model comprises a left bracket 3, a right bracket 7 and a breaker 11 fixed between the left bracket 3 and the right bracket 7. A main shaft 2 and a flip drive shaft 1 are connected between the left bracket 3 and the right bracket 7, wherein the main shaft 2 is used to connect to the boom 9 of the excavator or loader, and the flip drive shaft 1 is used to connect to the flip cylinder on the boom 9. Under the action of the flip cylinder, the left bracket 3 and the right bracket 7 drive the breaker 11 to flip around the main shaft 2 to change the direction of the breaker 11. The left bracket 3 and the right bracket 7 are connected to each other by six bracket bolts 4.

[0020] like Figure 1 , a connecting plate 6 is fixedly mounted on the left bracket 3 and the right bracket 7 respectively. The embodiment of the utility model includes a clamping assembly 5, such as Figure 2, the clamping assembly 5 includes a base plate 501, which is fixedly connected to two connecting plates 6.

Specifically, the left clamping plate shaft 503 is rotatably connected to the left clamping plate 506 through a front and rear clamping plate shaft sleeve, and the right clamping plate shaft 508 is rotatably connected to the right clamping plate 507 through a front and rear clamping plate shaft sleeve. The rotation connection through the shaft sleeve means that a splint shaft sleeve is installed on the splint shaft, the root of the splint is connected to the splint shaft sleeve on the same side, and the splint can rotate around the splint shaft on the same side along with the splint shaft sleeve on the same side.

[0021] The clamping plate shaft sleeve is fixedly connected to a control rod sleeve. The clamping assembly 5 also includes a left clamping plate control rod 504 rotatably connected to the left control rod sleeve and a right clamping plate control rod 509 rotatably connected to the right control rod sleeve.
