Embodiment 1
[0053] A three-door reclaimer has a chassis 1, a lifting structure and a reclaiming platform 5. The overall structure is as figure 1 As shown, there are wheels at the bottom of the chassis 1, which do not have the ability to actively rotate, so that the whole machine needs external force to move. Brake feet 1-4 are arranged next to the front wheel. When the brake feet 1-4 are stepped on, the brake feet 1-4 can be offset against the carrier surface of the reclaimer, so that the reclaimer has at least part of the gravity. It is assigned to brake top feet 1-4 to generate static friction to achieve positioning.
[0054] like figure 2 Shown is the structural diagram of the reclaiming platform 5 of the reclaimer. The material reclaiming platform 5 has a split double front door 5-1 and a scissor type side door 5-5, and the double front door 5-1 is installed on the material reclaiming platform through a limit block 5-2 and a torsion spring 5-3 5 on the frame 5-4, the front door 5...
Embodiment 2
[0064] A reclaimer, which has a chassis 1, a lifting structure and a reclaiming platform 5. The overall structure is as Figure 11 As shown, it is basically the same as Embodiment 1, the difference is that it is self-driven, such as Figure 4 As shown, it is driven by two rear active directional wheels 1-3, and is driven non-coaxially, each driven by an independent motor. Therefore, the forward, backward and turning directions of the reclaimer are all determined by the rotational direction and / or rotational speed difference of the two rear active orientation wheels 1-3. For example, when the direction of rotation and the rotational speed difference of the two rear active orientation wheels 1-3 are consistent, the reclaimer moves forward in a straight line or retreats in a straight line; if they all rotate forward, the rotation speed of the left wheel is greater than that of the right wheel. Then the reclaimer turns right while advancing.
[0065] The difference is also that...
