Abstract
Description
- The present invention relates to a separator bucket device comprising a grid for separation of excavated material, especially road material containing gravel, of the kind described in the introduction of
claim 1. - Separator buckets of the above-mentioned kind are known (Tojo Maskin, Färila, Sweden) and are usually mounted on wheeled loaders which after cutting of road borders by means of, for example, an excavator take care of the road material cut away in order to return gravel to the road and to remove material unsuitable to be used as road surfacing.
- A disadvantage of the known separator buckets is that parts of these have a limited life and must be exchanged rather often, which is time-consuming and uneconomical. This particularly applies to the rubber bushings and the bearings connecting the eccentrics of the drive shaft with the grid portions forming a grid.
- It is an object of the present invention to improve the known separator buckets and to eliminate their above-mentioned disadvantages in order to ensure perfect functioning during a long period of time and to facilitate removal and mounting of parts, when worn parts have to be exchanged.
- This object is achieved by giving the device according to the invention the features stated in the characterizing portions of the claims.
- Figure 1 is a partly cut away perspective view of a separator bucket comprising the device according to the invention,
- Figure 2 is a schematic view, seen from the rear, of details of the device according to Figure 1,
- Figure 3 is a side view of the details according to Figures 2 and 3, seen from the right, and
- Figure 4 is an exploded view of details of the device according to Figures 1-3.
- The separator bucket shown in Figure 1 and indicated by 1, comprises a
rear part 2, twoside walls 3, acutting plate 4 and aframe 5 extending between theside walls 3. Said parts are welded to each other. Thebucket 1 has no real base but is provided with a grid in the form of two grid portions 6 and 7 partly inserted in each other. Each grid portion comprises a number of parallel rods 6a and 7a respectively, one end of each rod being rotatably connected with a shaft mounted between theside walls 3 adjacent to thecutting plate 4. The other end of each rod 6a is connected with afront plate 9, and the other end of each rod 7a is connected with arear plate 10 which is parallel to thefront plate 9 and located partly under the same. Theplates - On the
frame 5 there are mounted four bearing brackets 11, in which adrive shaft 12 is rotatably mounted. Thedrive shaft 12 is driven by ahydraulic motor 13 mounted on theframe 5. Thedrive shaft 12 is provided with four eccentric discs 14 (Figures 3 and 4) surrounded by bearinghousings drive shaft 12, the eccentric discs 14 located in the bearinghousings 15 are displaced 180° relative to the corresponding parts of two other eccentric discs located in the bearinghousings 16. - The
bearing housings 15 are connected with thefront plate 9, and the bearinghousings 16 are connected with therear plate 10 in the way described below and shown especially in Figure 4. - The
bearing housings spring steel member 18 with welded reinforcement plate 23 is provided with a hole 18a. A conical sleeve 19 fits to the body 17 and into the hole 18a. After these details have been mounted, ascrew 20 is inserted in the sleeve 19, a washer 21 having previously been inserted between the sleeve and the screw head, and is screwed into the body 17. Ascrew 22 passed through a hole 18b in thespring steel member 18 is then screwed into the projection 15a, 16a. - By means of the ends facing away from the
shaft 12, thearms 18 are connected with theplates arms 18 facing towards theshaft 12 are connected with the projections 15a, 16a, as shown in Figure 4 wherefore an explanation will not be required. The details of the lower attachment device shown in Figure 4 are provided with the same reference numbers, though primed, as the corresponding details of the upper attachment device. - By means of the above described attachment devices 17-22 and 17'-22' there is provided a play-free, easily dismountable and mountable as well as reliable connection between the bearing
housings - Below is a brief description of the mode of operation of the bucket.
- After the bucket has received the road material excavated, the
motor 13 is started, theplates housings 15 acted on by the eccentric discs 14 displacing the associatedarms 18 upwardly while the two other bearinghousings 16 acted on by the eccentric discs 14 displace the associated arms downwardly, and vice versa. Hereby, the two grid portions will receive contrary rotary movements about theshaft 8 such that large pieces of, for example, soil, will be disintegrated, and gravel and other small particles will enter the spaces between the rods and fall through these on to the road, whereas large pieces of, for example, turf will stay on the grid. The rotary movements of the rods 6 and 7 are very quick, and since the distance between the rods is greatest at theplates 9 and 10 (around 1-3 cm) most of the road material will fall through the grid near these, especially since thebucket 1 is suitably inclined somewhat to the rear during separation. - The horizontal displacements between the bearing
housings plates flexible members 18, which are bent the most at their lower parts over the plates 23'.
