Problems solved by technology

[0002] The defect of the original crank impact mechanism is that the crank drives the guide rod to rotate, and the guide rod directly transmits the power to the impact rod. The impact rod impacts the coal mining head or drives the coal mining head to reciprocate. The rod moves back and forth in the guide rail, and the lateral force transmitted from the guide rod to the impact rod forms a shear on the guide rail, which causes great damage to the guide rail. The impact force of the punch rod is greatly damaged, which greatly reduces the practical application efficiency of power. Reduced service life of the shearer

Embodiment 1

[0059] Figure 1 to Figure 3 It is the pendulum drive straight flushing coal scraper described in Embodiment 1. The coal shearer includes a fuselage on which a frame, a traveling device, an impact device 1 , a driver 2 and a traction device 4 are arranged. The running gear in the present embodiment adopts running guide rail 3, figure 1 The running guide rail 3 shown is a rack and pinion structure; figure 2 The running guide rail 3 shown is a crawler belt. Start the driver 2 to make the whole body move along the moving guide rail 3, and drive the impact device 1 to impact the falling coal.

[0060] The impact device adopted in this embodiment is a shoveling device whose rotational force becomes a linear impact force. There is a guiding mechanism. The rotary force becomes linear impact force and the shovel device includes a rotary mechanism, a swing rod mechanism and a shovel mechanism. The shovel mechanism 5 includes a shovel head 5.1 and a shovel stroke component 5.2, t...

Embodiment 2

[0071] Figure 4 and Figure 5 It is the pendulum drive straight flushing coal scraper described in embodiment 2. In this embodiment, one end of the shovel stroke part 5.2 is fixedly connected to the shovel head 5.1, and the other end is hinged to the straightening link 6.4 of the swing rod 6.3. The frame is provided with a guide mechanism, and the straightening connecting rod 6.4 drives the impact stroke part 5.2 and the shovel head 5.1 to perform linear reciprocating motion along the guide mechanism.

[0072] Others are with embodiment 1.

Embodiment 3

[0074] Figure 6 and Figure 7 It is the pendulum drive straight flushing coal scraper described in embodiment 3. In this embodiment, the rotating mechanism 6.2 includes a rotating shaft 6.1, a rotating handle 6.21 and a guide rod 6.23. One end of rotating handle 6.21 is connected with rotating shaft 6.1, and the other end is connected with guide rod 6.23, and the other end of guide rod 6.23 is connected with an end of fork 6.3, and the other end of fork 6.3 is fixed. The rotation of the rotation shaft 6.1 drives the rotation of the rotation handle 6.21. While the rotation handle rotates, the power is transmitted to the swing rod 6.3 through the guide rod 6.23, so that the swing rod 6.3 swings, and the swing of the swing rod 6.3 drives one end of the straightening rod 6.4 to drive the impact. The rod 9 reciprocates in a straight line along the shovel stroke part 5.2 and the guide mechanism. During the forward movement of the impact rod 9, the impact shovel head 5.1 and the s...
