Abstract
The invention relates to a percussive grabbing machine comprising a firs wire rope, a second wire rope, a main support, a moving support capable of moving up and down in relative to the main support, a rocker and a bucket. The bucket is connected to the bottom of the main support. A first pulley set and a second pulley set are fixedly and sequentially connected to the main support below the moving support. A third pulley set is fixedly connected inside the moving support. The first wire rope is wound on the first, second and third pulley sets and is finally fixedly connected with the moving support, so that the first pulley set and the moving support thereof can approach the second and third pulley sets when the first wire rope is lifted up. The end of the second wire rope is fixedly connected with the moving support. Two ends of the rocker are connected with a sliding support and the bucket through a transverse shaft. The sliding support slides down to drive the rocker to expand; the rocker drives the bucket to open and close. The pulley set of multiple moving pulleys and the combination of multiple wire ropes allow the bucket of the machine to open and close and move more stably and more efficiently, and mechanical force is more saved.

[specific embodiment]
Of the present invention clearer in order to make, be described further in conjunction with the accompanying drawings and embodiments the scope be not intended to limit the present invention for the present invention.
Embodiment 1
As shown in Figure 1, 2, the present embodiment comprises the first wire rope 6, the second wire rope 7, main support 14, travel(l)ing rest 21, Rocker arm 5 and the scraper bowl that can slide up and down with respect to main support 14, and described scraper bowl is movably connected in described main support 14 bottoms,
The first assembly pulley 17 has a pulley, and the second assembly pulley 18 has two pulleys, and two pulleys are arranged on the 3rd assembly pulley 24.The installation that meets at right angles of the first assembly pulley 17 and the second assembly pulley 18, and the wire rope of this two assembly pulleys turnover and the 3rd assembly pulley 24 are on same line.These three assembly pulleys all adopt sealing self-lubricating mode, prevent that in use outside sandstone, mud etc. from entering its inside, affects the rotation of pulley.
As shown in Figure 3, at first the first wire rope 6 enters in 18 1 pulleys of the second assembly pulley by guide wheel for steel wire one, guide wheel for steel wire two, out enter in 24 1 pulleys of the 3rd assembly pulley, enter again in 17 1 pulleys of the first assembly pulley, enter again in 24 second pulleys of the 3rd assembly pulley, enter again in 18 second pulleys of the second assembly pulley, out be fixed together with wire rope engaging lug two.The second wire rope 77 is direct and wire rope engaging lug one is fixing.
The second wire rope 7 terminations are fixedly connected with travel(l)ing rest 21, and described Rocker arm 5 two ends are connected with scraper bowl with described sliding support by transverse axis, and described sliding support down sliding drives the Rocker arm 5 expansion, and Rocker arm 5 drives scraper bowl and carries out folding.
The movable protective sleeve 11 of wire rope adopts the arc mode, in use protects wire rope to rupture due to up and down.
When the first wire rope 6 is stressed while up drawing, the distance of the 3rd assembly pulley 24 and the first assembly pulley 17, the second assembly pulley 18 shortens, and travel(l)ing rest device 2 is moved downward, and makes Rocker arm 5 to external expansion, pulls 35 one-tenth 95 °～110 ° of arc scraper bowls to open and unloads soil.When the second wire rope 7 is stressed while up drawing, the distance of the 3rd assembly pulley 24 and the first assembly pulley 17, the second assembly pulley 18 is elongated, travel(l)ing rest device 2 is moved upward Rocker arm 5 is inwardly shunk, and makes arc scraper bowl 35 closures grab soil.
