[0002]

2. Description of the Related Art FIG.
FIG. 1 is an overall side view showing an example of a self-propelled crushing machine described in Japanese Patent Publication No. 7-No. In the self-propelled crushing machine shown in FIG. 22, a crushing machine (same as a crushing device) 8 is provided at an intermediate portion in the longitudinal direction of a vehicle body 1 having a pair of right and left traveling bodies 7, 7 and an operator boarding floor to which a control member is attached. A hopper 11 at one end in the longitudinal direction of the vehicle body so as to be substantially straight with the crusher 8;
A power source such as an engine 10 and a hydraulic pump are provided on the other side in the longitudinal direction, and a crusher motor is provided below the hopper 11.
Discharge conveyors 16 are respectively arranged between the traveling bodies 7, 7 below the vehicle body 1, and the hopper 11 and the horizontal feeder 5 are arranged.
1 is supported above the vehicle body 1 by a gantry 50, and the crusher motor and the crusher 8 are connected by a belt,
By projecting the discharge conveyor 16 to the outside in the longitudinal direction of the vehicle body 1 on the hopper 11 side, all the elements directly related to the crusher 8 are concentrated on one side in the longitudinal direction of the vehicle body 1 and the hopper 11 and the discharge conveyor 16 So that the discharge end is closer.

[0003]

In a self-propelled crushing machine according to an embodiment of the prior art shown in FIG. 22, a vehicle body 1 is connected to an upper portion of a traveling body 7 and a hopper 11 is provided on one side of the vehicle body 1, for example, on the front side. The engine 10 or the like as a driving source is mounted on the rear side, and the crushed material supplied to the hopper 11 is crushed by a crusher 8.
To be crushed. Since the crusher 8 is at a position close to the hopper 11, the crushed crushed material crushed by the crusher 8 is conveyed by a discharge conveyor 16 in a forward direction below the hopper 11. . However, the rear end A of the rear portion of the vehicle body 1 on which the engine 10 and the like are mounted protrudes rearward from the rear end B of the traveling body 7 by a large dimension L, and the unloading conveyor cannot be mounted rearward. For this reason, depending on the situation at the site where the self-propelled crushing machine performs the crushing operation, it may be difficult to transport the crushed object to be crushed, and the working efficiency may be greatly reduced. The present invention enables a transfer device for sending out a crushed object to be crushed to be selectively mounted in a forward direction or a rearward direction of a vehicle body frame, so that the transferability by the transfer device and the workability in the crushing processing operation. It is another object of the present invention to provide a self-propelled crushing machine capable of improving work efficiency.

[0004]

A vehicle body frame having a pair of right and left traveling devices, a crushing device mounted in front of the body frame, a hopper for charging crushed objects disposed above the crushing device, A receiving portion that is attached to the vehicle body frame so that at least a part thereof is located between the pair of left and right traveling devices, and that is located below the crushing device and receives the crushed crushed object; A transport unit having a delivery unit for delivering the frame to the outside of the frame, wherein the transport device is detachably attached to the vehicle body frame, and the delivery unit is provided in a forward or rearward direction of the vehicle body frame. It can be selectively mounted to be located at

[0005] According to this, when the self-propelled crushing machine performs the crushing operation, the transfer device is selectively set to the front-out state and the rear-out state with respect to the body frame depending on the situation of the work site. The crushed crushed material can be sent to a front position or a rear position of the self-propelled crushing machine. Therefore, even if it is more appropriate to send the crushed crushed material to the rear of the self-propelled crushing machine due to restrictions at the work site, for example, the sending direction can be adjusted to the work site, greatly improving work efficiency. Can be done. In this case, the transfer device may be set separately for the front feeder and the rear feeder. However, if one transfer device is mounted to be reversed, it is necessary to set a plurality of types of transfer devices. Since there is no such device, the manufacturing cost can be reduced, and the state can be changed between the front-out state and the rear-out state as needed, which is more efficient.

Still further, the vicinity of the receiving portion is swingably attached to the vehicle body frame, and a height adjusting device for adjusting the height of the sending portion to the ground is provided over the vehicle body frame and the transfer device. In this case, the work efficiency can be further improved because the height of the sending section can be adjusted according to the sending location of the crushed object to be crushed. For example, by raising the delivery unit during traveling, it is possible to avoid contact with obstacles of the unloading device during traveling, and when loading crushed crushed objects on a transport truck, the height of the truck bed is used. This is convenient because the height of the sending section can be changed according to the condition.

A vehicle body frame having a pair of right and left traveling devices, a crushing device mounted on the vehicle body frame,
A hopper for charging the crushed object disposed at an upper portion of the crushing device, and a hopper for mounting the crushed object mounted at least partially on the vehicle body frame so as to be located between the pair of left and right traveling devices; A transport device having a receiving portion for receiving the crushed material and a sending portion for sending the crushed crushed material outward from the body frame, wherein the body frame is connected to the traveling device and the crushed A base frame mounted with a device and a hopper, and a power line frame mounted with a drive source such as an engine and a hydraulic pump connected to a rear portion of the base frame and driving the crushing device and the like, The power line frame was mounted on the base frame so that the ground height could be adjusted.

[0008] According to this, for example, when the above-described transport device is mounted in a rearward-extended state, the distance between the power line frame located behind the vehicle body frame and the transport device becomes narrower, and the crushed cover during transport is reduced. The crushed material may come into contact with the power line frame and fall abruptly to the side from the transfer device.At this time, the power line frame and the transfer device are adjusted by adjusting the height of the power line frame to the ground. Can be appropriately maintained, and workability can be improved. Also, even when the transport device is in the advanced state,
For example, it is possible to avoid contact between an obstacle at the work site and the power line frame, and the workability can be improved. If the power line frame does not need to be raised, it can be lowered to the same position as the base frame, thereby lowering the center of gravity and ensuring the stability of the self-propelled crushing machine itself. .

Further, the power line frame is detachable from the base frame, and the power line frame is attached to the base frame via a height adjusting member, so that the power line frame has a ground height. In the case where the adjustment is possible, the ground height of the power line frame can be increased by the required height with a simple configuration.

Further, in the case where the position of the transfer device is freely adjustable in the front-rear direction, when the carry-out device is mounted in the rearward position with the carry-out device reversed as described above, the power line projecting rearward is provided. The transport device can be moved backward so that the sending section is located at a position behind the frame with a margin. In this case, it is easy to set a plurality of mounting positions for the transfer device mounting portion on the vehicle body frame side in the transfer device, and to adjust the position by selectively mounting.

Further, the transfer device is attached to a plurality of arms attached to the body frame so as to be swingable in the front-rear direction, so that the transfer device is movable in the back-and-forth direction. In the case where the parallel link is formed in the direction, the position can be adjusted to an arbitrary position, and the parallel link formed by the plurality of arms can maintain the ground angle of the transfer device, and the transfer can be performed. The transportability of the device is not impaired. If the arm is swung by a hydraulic cylinder or the like, the workability can be further improved.

According to the present invention, when the self-propelled crushing machine performs the crushing process, the transport device (belt conveyor) is selected between the front-out state and the rear-out state with respect to the body frame depending on the situation of the work site. The crushed crushed object can be sent to a front position or a rear position of the self-propelled crushing machine. Therefore, even if it is more appropriate to send the crushed crushed material to the rear of the self-propelled crushing machine due to restrictions at the work site, for example, the sending direction can be adjusted to the work site, greatly improving work efficiency. Can be done. In this case, the transfer device may be set separately for the front feeder and the rear feeder. However, if one transfer device is mounted to be reversed, it is necessary to set a plurality of types of transfer devices. Since there is no such device, the manufacturing cost can be reduced, and the state can be changed between the front-out state and the rear-out state as needed, which is more efficient.

Further, the vicinity of the receiving portion is swingably attached to the vehicle body frame, and a height adjusting device for adjusting the height of the sending portion to the ground is provided over the vehicle body frame and the transfer device. In this case, the work efficiency can be further improved because the height of the sending section can be adjusted according to the sending location of the crushed object to be crushed. For example, by raising the delivery unit during traveling, it is possible to avoid contact with obstacles of the unloading device during traveling, and when loading crushed crushed objects on a transport truck, the height of the truck bed is used. This is convenient because the height of the sending section can be changed according to the condition.

A power line frame equipped with a driving source such as an engine of a self-propelled crushing machine, a hydraulic pump, etc.
It is attached to the base frame of the body frame so that the height can be adjusted. According to this, for example, in a case where the above-described transport device is mounted in a rearward-extended state, the distance between the power line frame located behind the vehicle body frame and the transport device is reduced, and the crushed crushed material being transported is reduced. It may come into contact with the power line frame and suddenly fall to the side from above the transfer device.At this time, by adjusting the height of the power line frame to the ground, the distance between the power line frame and the transfer device can be reduced. It can be kept properly and workability can be improved. In addition, even when the transport device is set in the front-out state, for example, it is possible to avoid contact between an obstacle at the work site and the power line frame, thereby improving workability.
If it is not necessary to raise the power line frame, it can be lowered to the same position as the base frame,
Thereby, the stability of the self-propelled crushing machine itself can be secured by lowering the center of gravity.

Further, the power line frame is detachable from the base frame, and the power line frame is attached to the base frame via a height adjusting member, so that the power line frame has a ground height. In the case where the adjustment is possible, the ground height of the power line frame can be increased by the required height with a simple configuration.

Further, in the case where the position of the transfer device is freely adjustable in the front-rear direction, when the carry-out device is mounted in a rearward position with the carry-out device reversed as described above, the power line projecting rearward is provided. The transport device can be moved backward so that the sending section is located at a position behind the frame with a margin. In this case, it is easy to set a plurality of mounting positions for the transfer device mounting portion on the vehicle body frame side in the transfer device, and to adjust the position by selectively mounting.

Further, the transfer device is attached to a plurality of arms attached to the body frame so as to be swingable in the front-rear direction so as to be swingable in the front-rear direction, and is movable in the front-rear direction. In the case where the parallel link is formed in the direction, the position can be adjusted to an arbitrary position, and the parallel link formed by the plurality of arms can maintain the ground angle of the transfer device, and the transfer can be performed. The transportability of the device is not impaired. In the case where the arm is swung by a hydraulic cylinder or the like, workability can be further improved.

As described above, according to the present invention, the workability of the crushing operation can be greatly improved.
