Definitions
- the present invention relates to a bucket intended to be carried by an arm or the corresponding and comprising a bottom and back part and opposing side parts, which parts are arranged to, together, form a load space having an opening with an edge part connected to the bottom part of the bottom and back part and running sideways in the bucket.
- Buckets of substantially this kind are previously known and are used for example for excavating. Buckets of this kind are comparatively limited as far as area of use is concerned.
- the present invention relates to a bucket, which offers a substantially broader area of use.
- the invention refers to a bucket according to the introductory part of the attached claim 1 such a bucket is known from US-A-5241764 .
- the bucket is especially characterized in what is specified in the characterizing part of said claim.
- Figs. 1 designates a bucket for e.g. excavating etc. arranged to be carried by means of a, not shown, machine arm 2, intermittently marked in Fig. 4 or the like for man ⁇ uvring.
- 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.
- 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 open position, in which the sorting part is substantially exposed, and a second position, a closed position, in which the sealing part sealingly substantially connects to the sorting part.
- 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 open position, in which the sorting part is substantially exposed, and a second position, a closed position, in which the sealing part sealingly substantially connects to the sorting part.
- roof part 11 designates a roof part, which bridges the side parts and, according to the shown, preferred embodiment, carries at least one, but preferably two hydraulic cylinders 12 for swinging the sealing part between said two positions.
- the roof part preferably also carries a fastening arrangement 13 for said arm or the corresponding.
- the sorting part comprises a plurality of substantially 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 preferred that further elements 15 are provided and running substantially perpendicular to the rod shaped elements and connecting them.
- the sealing part at each of its two opposing 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.
- the sealing part at its free edge 18, comprises 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 corresponding.
- the fixing means are arranged to run along the edge part, preferably on a 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 20-30°, preferably about 26°.
- 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 suitable manner.
- 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 suitable manner.
- 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.
- devibrating parts made of e.g. rubber or the 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 or the corresponding.
- devibrating parts made of e.g. rubber or the like elastic material
- a gate 13' e g of substantially known kind, attached to the bucket by means of fastening 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 13"" of the gate for devibration, as schematically shown in Fig. 7.
- the sorting part removably arranged and hereby arranged to be attached internally between the side parts 4.
- the sorting part comprises two opposing frame elements 26, between which rod shaped elements 14 are running.
- 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 inserted in a notch 30 in said frame element.
- the 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 necessary movability and therewith efficient vibration.
- 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, 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.
- the sealing part In order to obtain a sorting configuration of the 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.
- the invention offers several alternative functions of a bucket by comparatively simple means.
- parts for different goods size of passing goods may be arranged in the bucket.
- the sorting part may be designed to have a more distinct net configuration or as a disc shaped part provided with holes.
