Japanese Utility Model Publication No. 60-16667 is known. As shown in FIG. 4, the rear plate 3 (attachment portion) rotatably attached to the backhoe and the front plate 2 having an opening provided at the front end are connected by a vertical frame 4. The wire mesh 5 is attached to the outer periphery of these vertical frames. Then, when earth and sand, gravel, etc. are scooped into the trommel 1 from the opening of the front plate, if the front side is rotated while keeping the front side higher than the rear side, small earth and sand, gravel, etc. fall from the holes of the wire mesh 5. And sediment, gravel, etc. are sieved.

That is, the rear portion is loaded with more earth and sand than the front portion. In addition, when the trommel 1 rotates, the inclination angle is increased so that the larger the amount of scooped sand and gravel, etc., the larger the lump does not jump out of the front opening, so that the amount of sediment accumulated on the rear side is increased. There is a problem that the height becomes large, the effective area of the sieve used for sieving becomes extremely small, and the efficiency is reduced. Furthermore, in the sieving work, earth and sand, gravel, etc. fall from only the wire mesh 5,
There is a problem that it takes time to complete the sieving of earth and sand, gravel, and the like at a portion in contact with the rear plate 3.

Will be described. The trommel 21 includes a mounting portion 22 attached to the bracket 13 and a sieve body 23 having a bottomed cylindrical shape. The sieve body 23 has a cylindrical, for example, cylindrical peripheral sieve 25 having a large number of separation holes 24 and a bottom sieve 26 and a bottom sieve 26. It is connected to the outer peripheral portion of the mounting portion 22 via a plurality of, for example, four vertical frames 27 attached.

The bottom sieving portion 26 is attached substantially in parallel with the attachment portion 22 with an interval 30 as in the second aspect of the present invention. This interval 30 is, for example, 100 to 3 depending on the material to be sieved.
It is set to 00 mm.

The separation hole is not limited to a wire mesh and may be formed by punching a plate material. You may comprise with a punch metal etc. Further, when the strength of the bottom of the sieve body 23 is sufficiently ensured, the bottom sieve part 26 of the sieve body 23 is connected to the mounting part 22 without any gap, and the bottom itself of the sieve body 23 is used as the mounting part 22. Is also good.

で示すようになる。Next, the operation of the above configuration will be described.
The excavator 29 is thrust into the piled earth and sand, and the earth and sand is scooped up in the trommel 21. Then, the hydraulic cylinder 14 is operated to rotate the trommel 21 in the direction of the arrow A, and as shown in FIG.
2 is lowered, the upper surface of the earth and sand
It becomes as shown by.

下する。Then, when the hydraulic motor 15 is driven, the trommel 21 is rotated via the transmission device 16. The earth and sand disposed on the front side moves along the inner surface of the peripheral sieve portion 25, and the small earth and sand falls downward from the separation hole 24. On the other hand, the earth and sand disposed at the rear moves along the inner surfaces of the peripheral sieve 25 and the bottom sieve 26. Then, small sediment in contact with the peripheral sieve portion 25 is separated into the separation holes 2.
The small sediment that falls directly from 4 and contacts the bottom sieving part 26 falls downward from the separation hole 24 through the space 30.

向上したことが確認された。As described above, according to the above-described embodiment, since the earth and sand disposed at the rear portion is sieved from both sides of the peripheral sieve portion 25 and the bottom sieve portion 26, the area of the sieve can be increased. And the sieving efficiency is significantly improved. According to the test of the applicant, the sieving efficiency is about 30 to 35% when the peripheral sieving part 25 rotates at a peripheral speed of 56 m / min.
It was confirmed that it improved.

Since the sediment picked up by the trommel 21 is sieved from both sides of the peripheral sieving portion 25 and the bottom sieving portion 26, the sieving efficiency is remarkably improved. Since the total area of the sieve portions 25 and 26 increases, the length of the peripheral sieve portion 25 can be shortened. Since the trommel 21 is attached to the bracket 13 in a cantilever state, the fact that the length of the peripheral sieve portion 25 can be shortened can significantly reduce the load on the bracket 13 and reduce the load on the backhoe 11.

The bottom screen 33 is attached. The bottom sieving part 33 is formed by stretching a wire net like the peripheral sieving part 25, and has a large number of separation holes 24. The intersection angle with the peripheral sieving part 25 is obtuse (> 90 degrees). . This embodiment also has the same effects as the above embodiment.
