EFFECT: perfected design. 3 cl, 4 dwg
The present invention relates to a screening, crushing or mixing the bucket, made in the form of a bucket or the bucket of a loader, comprising a bottom plate, side walls and working the drums, which are located at the rear of the bucket, which is made to rotate around their axes and which, while rotating screened, crushed or mixed material in the bucket and at the same time serves screened, crushed or mixed material out of the bucket between the working drums or through them, and also covers mechanical drives and bearings of the working drums, these enclosures are limited frame plates to which can be attached to the bearing housing the drums. The bucket of this type is known from international patent application WO 0158595 the same applicant. The disadvantage of this and other famous buckets is that the gap between the rotating shaft and the frame is increased wear. The material in the bucket continuously presses in this gap, a new wear-intensive material, which ultimately leads to damage of the bearings. The aim of the invention is a solution to this problem through design, which prevents direct pressure of the material existing in the gap. This goal is achieved through sozdaniya according to the invention, distinctive features of which are disclosed in claim 1 of the attached claims. The present technical solution is based on using a separate antisplash element made of wear-resistant steel. In a preferred embodiment of the invention antisplash element is shared with the end flanges of the working drums. Antisplash element prevents direct pressure of the material existing in the gap between the frame and the shaft, and also, in a preferred embodiment of the invention, forms together with the front flange of the labyrinth configuration. Thus, the area that you want to isolate, subject only to the influence of dust. One embodiment of the invention, described in detail below with reference to the accompanying drawings, on which: figure 1 shows a perspective view of a partially open bucket according to the invention with detached upper drum work, figure 2 shows an enlarged fragment of figure 1, figure 3 shows another perspective view of the bucket shown in figure 1, figure 4 shows another type of diagonally partially disassembled bucket according to the invention without working the drums. The bucket according to the invention can be attached to the excavator or Kovshova loader, which on the upper side of the bucket imets the fastening lugs 8. The bucket includes a bottom plate 1, side walls 2 and the working drums 3, which are located at the rear of the bucket, which is made to rotate around their axes and which, while rotating screened, crushed or mixed material in the bucket and at the same time serves screened, crushed or mixed material out of the bucket between the working drums 3, or through them. Between the flanges of the working drums 3 can be assigned to different types of crushing teeth, which is not shown. To the rear of the side walls 2 joined housings 4 mechanical drives and bearings of the working drums 3. In the shown embodiment, the housings 4 are separated from the inner part of the bucket frame plates 5, to which may be attached to the housing 6 of the bearings of the working drums 3. In the shown embodiment, the frame plate 5 are a direct continuation of the side walls 2 and made of the same material as the side walls 2. Working drums 3 are end flanges 9, spaced from the side frame plate 5 opposite to the housing 6 of the bearings adjacent to the frame plate 5. End flanges 9 are rotated together with each work drum 3, i.e. they are attached to the shaft of the drum 3. On the inner side of the frame plate 5 and/or the inner wall 2 Zack is aplan antisplash element 10, which takes place near the end flange 9, so that at least a portion of each end flange 9 is located between the frame plate 5 and antisplash element 10. Antisplash element 10 sends the processed material by a gap between the end flange 9 and the frame plate 5. In the shown embodiment, the dust control element 10 includes a cover plate 10, which is perpendicular to the axis of the working drums and which partially passes over the end flanges 9. Antisplash element 10 has a recess 11 for accommodating the shafts of the working drums 3. The notches or seats 11 allow to replace antisplash element 10 without disconnecting the shaft of the working drum. At the same time, the design on the rear side in the direction of movement of the material there is a gap, therefore, the material falling between the mudguard element 10 and the frame plate 5, easily removed therefrom. 1. Screening, crushing or mixing bucket, made in the form of a bucket or the bucket of a loader, comprising a bottom plate (1), side walls (2) and the working drums (3), which are located at the rear of the bucket, which is made to rotate around their axes and which, while rotating screened, crushed or mixed material in the bucket and at the same time serves sifted, raskob the military or mixed material out of the bucket between the working drums (3), or through them, and covers (4) mechanical drives and bearings of the working drums (3), these enclosures are limited frame plates (5), attached to the housing (6) of the bearings of the working drums (3), characterized in that on the inner side frame plate (5) and/or the inner wall (2) is fixed to the mudguard element (10)perpendicular to the axis of the working drums (3) and having indentations (11) to accommodate the shafts of the working drums (3), the working drums (3) have end flanges (9)located on the side frame plate (5), opposite to the housing (6) of the bearings adjacent to the frame plate (5), and these end flanges (9) are rotated together with each working cylinder (3)being attached to its shaft, and dust control element (10) is near the end flanges (9), so that at least a portion of each end flange (9) is located between the frame plate (5) and dust control element (10)to direct the material being processed by the gap between the end flange (9) and frame plate (5). 2. Ladle according to claim 1, characterized in that the dust control element (10) comprises a plate (10)located perpendicular to the axis of the working drums (3), which partially passes over the end flange (9).
