In the Figs. 1 designates a bucket for e.g. excavating etc. arranged to be carried by 10 means of a, not shown, machine arm 2, intermittently marked in Fig. 4 or the like for maneuvring. The bucket comprises a bottom and back part 3 and opposing side parts 4, as shown in Fig. 1, 2 and 4. Said parts together form a load space 5 with an opening 6 with an edge part 8 connected to the bottom part 7 of the bottom and back part and running sideways in the bucket. 15 According to the invention said bottom and back part comprises an internal sorting part 9, Fig. 2, through which among other things liquid and comparatively finely distributed goods, e.g. sand and soil, can pass, as well as an external sealing part 10, which is swingable towards and from the sorting part between a first position, an 20 open position, in which the sorting part is substantially exposed, and a second posi tion, a closed position, in which the sealing part sealingly substantially connects to the sorting part. 11 designates a roof part, which bridges the side parts and, according to the shown, 25 preferred embodiment, carries at least one, but preferably two hydraulic cylinders 12 for swinging the sealing part between said two positions. The roof part prefera bly also carries a fastening arrangement 10 for said arm or the corresponding. According to a preferred embodiment the sorting part comprises a plurality of sub 30 stantially rod shaped elements 4 running between the side parts and distributed along the bottom and back part for the formation of a sorting configuration. It is also WO 99/32732 4 PCT/SE97/02205 preferred that further elements 15 are provided and running substantially perpen dicular to the rod shaped elements and connecting them. According to the embodiment shown, the sealing part at each of its two opposing 5 sides comprises a flange part 16 turned to the sorting part and at least partly toothed, so that objects 17 as intermittently lined in Fig. 2, can be gripped and held between the sealing part and the sorting part. Also according to the embodiment shown the sealing part, at its free edge 18, com 10 prises at least one fixing means 19 with substantial tooth shaped section, Fig. 3, which fixing means is arranged to sealingly connect to the edge part 8 arranged to the side parts and the sorting part, which edge part is intended to be the active edge part when excavating etc. and preferably to be made of scraper steel or the corre sponding. The fixing means are arranged to run along the edge part, preferably on a 15 somewhat higher level than the edge part bottom side 8, whereby the fixing means, for good sealing, is sealed by means of sloping surface 19' turned to the edge part and fitted against a surface of the edge part elevating against the fixing means and having the corresponding inclination, Fig. 3. The inclination angle v is e.g. about 20-300, preferably about 260. 20 The fixing means are also arranged to fix various tools such as an asphalt cutter 20, Fig. 6, or a ripper element 21, having one or more digging teeth 22, Fig. 5, to the edge part by squeezing and where the respective tools comprise a fixing piece 23, arranged to be applied to the edge part and to be fixed by squeezing to the same in a 25 suitable manner. According to a further embodiment vibration means 24 are provided and connected to the sorting arrangement, e.g. via said roof part, as intermittently marked in Fig. 2, for promoting the sorting. To do this, devibrating parts, made of e.g. rubber or the 30 like elastic material, are put into the fastening arrangement 13 for said arm or the corresponding in order to prevent vibrations to the sorting are transferred to the arm WO 99/32732 5 PCT/SE97/02205 or the corresponding. At the fastening arrangement 13 according to Figs. 7 and 8 is a gate 13', e g of substantially known kind, attached to the bucket by means of fas tening ears 13" and two axles 13"', where parts 25 made of elastic material are provided and arranged between the respective axle and the axle fastening points 5 13"" of the gate for devibration, as schematically shown in Fig. 7. In the especially preferred embodiment shown in Figs. 9-15 is said sorting part re movably arranged and hereby arranged to be attached internally between the side parts 4. According to the embodiment shown the sorting part comprises two oppos 10 ing frame elements 26, between which rod shaped elements 14 are running. For at tachment two flange parts 28 are provided e.g. in the forward edge 27 of the sorting part arranged to be inserted and held under corresponding flange parts 28 of the edge part 8 running between the side parts and internal pins 29 arranged to be in serted in a notch 30 in said frame element. 15 24 designates vibration means, such as a motor with an excenter weight, arranged on the removable sorting part for vibrating the same. The sorting part is preferably arranged between the side parts with a substantial gap in order to allow the neces sary movability and therewith efficient vibration. 20 In Figs. 12-15 31 designates a combined ripper and asphalt cutting tool arranged to be helt by means of the bottom and back part in an asphalt cutting position, Figs. 12 and 14, or a ripping position, Figs. 13 and 15. The tool comprises two notches 32, 33 running in the width direction of the bucket, in which notches the edge part 8, 25 Figs. 12 and 13, or the free edge 18 of the sealing part, Figs. 14 and 15, are intended to be inserted for fixing of the tool as should be obvious from the Figs., whereby the tool is arranged, by means of support surfaces, to be able to be put on an underlay in substantially said positions, so that gripping and application of the tool can be done without manual action. 30 WO 99/32732 6 PCT/SE97/02205 The invention is applicable for buckets with a bottom and back part according to e.g. Fig. 1. The invention is also applicable for buckets of the clam shell type, Fig. 16, comprising two bottom and back parts arranged to be swung towards and from each other in order to grip goods in a hanging position. Hereby either one or both of 5 the two buckets parts be arranged with an internal sorting part 9 and an external sealing part 10 in principally the same way as a bucket according to e.g. Fig. 1, whereby the sorting part may be fixed or removable in the way described earlier. In the embodiment shown in Fig. 16 the respective bottom and back parts are swinga ble by means of cylinders 12 towards and from the respective sorting part and the 10 respective pair of such parts swingable towards and from each other by means of cylinders 12' for gripping by the bucket. The function of the bucket according to the invention should to a substantial part have been made obvious above. In order to obtain a sorting configuration of the 15 bucket, the sealing part is swung from the sorting part, whereby liquid and finely dispersed goods may pass from the load space through the sorting part. The sealing part is swung towards the sorting part in order to obtain a sealed bucket for ordinary use. 20 As should have been made obvious above the invention offers several alternative functions of a bucket by comparatively simple means. By means of a removable and, thus, exchangeable sorting part, parts for different goods size of passing goods may be arranged in the bucket. 25 Above, the invention has been described in association with exemplifying embodi ments. Of course, further embodiments and minor changes and complements may be imagined without leaving the substantial inventive idea. Thus, the sorting part may be designed to have a more distinct net configuration or 30 as a disc shaped part provided with holes.

WO 99/32732 7 PCT/SE97/02205 Thus, the invention should not be regarded as limited to the embodiments specified above but may be varied within the frame given by the attached claims.
