Small Mining Machine
5.2 Operation steps
5.2.1 The insertion board of transport pan is lowered to the ground. The
specific operations are shown in Figure 2-3 Operation Diagram.
5.2.2 Operate the machine to move forward, gather the stone together, and
then level the ground.
5.2.3 Confirm that the transferring vehicle enters into the unloading
part of the machine, and then the handle is pulled to the position
of positive transport.
5.2.4 Operate the pilot valve so that the big arm is lifted up, small arm
is extended out, and then the bucket is placed in the position
which aligns with the small arm. And then the big arm is lowered,
small arm is withdrawn (big arm is jogging up and down), so the
stone can be grilled into the transport pan. The rotary arm can
pick stones in a wide range. The appropriate withdrawal and
extension of bucket according to different distances will
facilitate stone picking. During picking, all kinds of arms cannot
be moved to the limit position, so as to avoid frequent transition
impact and shorten the service life of the machine. Meanwhile, it
can avoid high temperature caused by frequent overflow due to
overload valve. It shall be specially noted that the bucket cannot
directly hit the transport pan, otherwise it will cause the serious
deformation of the transport pan.
5.2.5 During picking, always check whether the scraper chain is in the
normal delivery. If stuck, the delivery shall be promptly stopped.
Otherwise, the temperature will rise rapidly due to overload, and
then the machine cannot continue to work. The method to solve
clamping of scraper chain: the joy stick for positive transport is
pulled in the neutral position; the joy stick for transport is
pulled back and forth so that the scraper chain achieves quick
positive
and negative impact so as to release the scraper chain. When there
are stones in the transport pan, the transport joy stick cannot be
stopped in the position of negative transport, otherwise the chain
or scraper may be broken, seriously affecting production.
5.2.6 To stop during walking, the pilot valve of brake pedal can be
placed in the neutral position. For long-time parking, the shovel
plate in front of machine shall be pressed on the ground.
5.2.7 Before walking or reversing of loader, the bell shall be started as
a warning signal.
