In addition to being installed oppositely, another guide roller (20) ··· is installed at the lower part of the main belt (13) and the lower part of the sub belt (16) to assist the effect of the guide roller (19). ing.
The guide roller (19) is free to move around the support shaft (21) and its function is improved by bringing the guide roller (19) close to the drive roller (12) as much as possible, and as shown in FIG. Is inclined with respect to the belt surface, and the guide surfaces (that is, peripheral surfaces) of the guide rollers (19) and (19) are mounted so as to support the loads acting on the main and sub belts (13 and 16). . Another guide roller (20) also has a structure conforming to this guide roller (19). Specifically, the guide roller (19) receives the main belt (13) and the sub belt (16) from behind them, and one of the guide rollers (20) and (20) is the lower part of the main belt (13). Is received from below, and the other one receives the sub belt (16) from behind. These optimum modes are appropriately determined in consideration of the load of the conveyed load and the bending of the main and sub belts (13) and (16).

Then, the lower part of the clod collecting and conveying device (6) constitutes a horizontal collecting part (6a), and the upper part of the device (6) forms a horizontal unloading part (6b).
It has been done.

Reference numeral (22) is a roller roller provided near the center of gravity of the machine body, and reference numeral (23) is a caster provided at the rear portion of the loading platform (7). The machine body is stably supported mainly by the roller rollers (22) and the casters (23) and the ground contact force of the clod collecting and conveying device (6).

Furthermore, as shown in FIG.
Means are provided to prevent spillage and the like. That is,
A pair of lateral aprons (25) and (25) are supported on the side covers (24) of the horizontal receiving portion (6a) so that the relative distance gradually becomes smaller in the transport direction, and the respective leading edges are provided. Is adhered to the upper surface of the main belt (13). Also, a pair of vertically oriented aprons (27) and (27) are supported in parallel with each other on the side edge of the rising portion (26) of the machine body, and the respective leading edges are brought into close contact with the front surface of the sub belt (16). At the bottom of the sideways apron (2

In addition, (28) ... In the figure is a towing arm for towing the soil mass collecting device (5) by the excavation device (1).

When working with the above device, the bucket (B) is placed on the loading platform (7) and both devices (1) (5) are pulled while the excavation device (1) pulls the clod collecting device (5). To be in working condition. As a result, the excavator (1) discharges the core (w) toward the rear by forming ventilation holes in the surface of the lawn claw cloth. The discharged core (w) is received by the front part of the horizontal receiving part (6a) of the clod collecting device (5), and then horizontally conveyed backward by the main belt (13). In this case, the front apron (25a) prevents the core (w) from falling off in front of the horizontal receiving section (6a), and the sideways aprons (25) (25) have a large front relative distance. Since it is small, the core (w) is gathered in the center of the main belt (13) along with the progress of horizontal conveyance together with facilitating the reception of the core (w) in the front part of the horizontal receiving section (6a),
In addition, it works to prevent falling out. Following this horizontal conveyance, the core (w) has a main belt (13) and a sub belt (16).
It is pinched by and and conveyed vertically. In this process, the guide rollers (19) (19) are the main and sub belts (13) (16).
The core (w) works to prevent the core (w) from spilling from each side edge, and the vertical aprons (27) (27) work to prevent the core (w) from falling off to the side of the airframe. After that, the core (w) is horizontally conveyed backward by the horizontal unloading section (6b),
It is dropped toward the inside of the bucket (B) and stored.

Thus, the clod collector (5) equipped with the present invention efficiently collects the core (w) excavated by the excavator (1).

5 and 6 are a perspective schematic view and an explanatory view showing a guide means similar to the guide rollers (19) and (19). That is, it is possible to provide the floating disks (29) and (29) instead of the guide rollers (19) and (19). The floating disc (29) is rotatably mounted on each outer side of the floating roller (14c) around the roller support shaft (30), and each side edge of the main belt (13) and the sub-belt (16). Both belts (13)
(16) is regulated so as not to be displaced in the width direction, and its effect is the same as that of the guide rollers (19, 19). Floating discs here (29) (29)
Is not fixed to the floating roller (14c) in order to smooth the rotational displacement of the main and sub belts (13) and (16).

(G) Effect of the Invention As is apparent from the above, according to the present invention, the guide rollers (19) and (19) are provided at the overlapping portion with the main and sub belts (16) and in the vicinity of the drive roller (12). Since it is arranged, the meandering prevention of the main and sub belts (13) and (16) is effectively achieved, and the conventional belt position adjustment is not required for a long time, and in particular, it overlaps with the main belt (13). The secondary belt (16) is the upper and lower floating rollers (14a).
Since it is a non-driving belt that is wound between (14a), the problem of meandering due to gradual deviation along the width direction becomes remarkable, but the peculiar problem is due to the simple configuration. The guide roller (1
9) (19) is installed so as to support the load of the main and sub belts (13) and (16), so the main and sub belts (13) and (16)
Thus, the load (core (w)) that is pinched and conveyed in the overlapping portion can be appropriately prevented from spilling from the side edges of the main and sub belts (13) and (16).
