Description

[Detailed Description of the Invention] This invention relates to a packet device for a continuous rotary excavator in which the cutting force of an excavating blade protruding from the front edge of a packet body is inclined in the excavation direction.

Conventionally, in continuous rotary excavators that continuously excavate trenches by rotating a wheel with many packets around it and towing it with a self-propelled vehicle, the front edge of the packets around the wheel There are multiple digging blades protruding from the top.

However, since these digging blades are arranged horizontally and in a straight line with respect to the excavation direction, the cutting force of each cutting blade is equalized, and if there is a hard rock layer underground, excavation becomes almost difficult.

This invention was made with the aim of solving this problem.The cutting blade protruding from the front edge of the packet body is tilted in the digging direction to increase the digging force per cutting edge of the continuous rotary excavator. The aim is to provide packet equipment to increase excavation capacity.

This invention will be described in detail below with reference to an illustrated embodiment.

In the figure, reference numeral 1 denotes a self-propelled vehicle that can run freely on crawler tracks 2, and the front end of a main frame 3 is connected to the rear part of a vehicle body 1a.

The rear end of the main frame 3 has a wire 4 extending from the vehicle body 1a side.
The main frame 3 is suspended by a wire 4 so that its rear end can be moved up and down by inserting and removing the wire 4, and the main frame 3 is provided with a wheel 5 rotated by a drive source (not shown).

A large number of packet bodies 6 are attached at intervals around the wheel 5.

Each packet body 6 is configured as follows, for example.

That is, as shown in Fig. 3, the side plates 6a, 6b and the bottom plate 6c are formed by bending a plate material of a suitable thickness, and the height of the side plate 6a, 6a, is lower than the other force 6b. There is.

This allows the bottom plate 6c to be connected between the side plates 6a and 6b.
is configured to be inclined sequentially from the higher side plate 6a to the lower side plate 6b.

The ends of each side plate 6a, 6b of the packet main body 6 are
High side plates 6a and low side plates 6b are fixed to each rim 5a of the wheel 5 by fasteners 7 so as to alternate.

The leading edge of the packet main body 60 in the rotational direction includes:
A plurality of excavation blades 8 are provided protrudingly spaced apart in the width direction.

When the self-propelled vehicle 1 is moved forward while rotating the wheel 5 in order to dig a groove, the excavating blade 8 protruding from the bottom of the high side plate 6a among the excavating blades 8 protruding from the packet body 6 is Deeper, and the digging blade on the other side will dig deeper into the ground.

As a result, the amount of excavated soil is reduced.75\The excavating force of the excavating blade 8 is increased, so it becomes possible to excavate even hard ground, and it is less difficult to excavate as in the conventional case.

In addition, since the bottom plates 6c of each packet body 6 are inclined so as to become deeper alternately, the imbalance in the digging reaction force applied to each digging blade 8 due to the difference in depth is offset by the front and rear packet bodies 6, so that the wheel No unbalanced load is applied to 5.

Further, the earth and sand contained in each packet main body 6 is transported above the wheel 5 and then dropped onto the conveyor 9, and is discharged to the side of the wheel 5 by the conveyor 9.

In the above embodiment, the digging blades 8 are arranged at the front and back of the packet body 6 by shifting their positions in the excavation depth direction, but the bottom plate 6c of the packet body 6 is horizontal as in the conventional case, The edge may be inclined with respect to the direction of rotation, and the cutting blade 8 may be provided on this leading edge.

In this case, as in the above embodiment, each packet body 6 is attached to the wheel #5 so that the front edge of the packet body 6 has an alternate slope.
By mounting as shown in the figure, the uneven load applied to the wheel 5 can be offset.

When excavating using the packet body 6, each of the excavating blades 8 digs into the ground one after another, so the excavating force per excavating blade 8 increases, making it possible to excavate hard ground.

Of course, the packet body 6 may be formed by combining both of the above embodiments, if necessary.

As detailed above, this idea is based on the fact that a plurality of digging blades are protruded from the leading edge of the packet body, which is provided at intervals around the wheel, with the cutting force being varied at an angle. Since the digging force is increased compared to one in which the cutting force is equalized for each cutting edge, it is also possible to excavate hard ground.

Since the direction of inclination of the housing excavator blades is alternately changed for each packet body, the uneven loads cancel each other out, so there is no risk of the wheel being deformed or damaged due to uneven loads.
