Definitions

  • the invention relates to a catch plate of a loader bucket intended for a motor vehicle with an upwardly and forwardly extending rear wall, which merges into an upper horizontal transverse edge, consisting of a main plate construction which extends over the full width of the loader bucket and consists of a central section which are each followed by an outwardly extending end section, the central section consisting of a projecting, approximately V-shaped sheet metal part, the legs of which form a front wall and a rear wall, which are connected to one another by a transverse edge, the said front wall being connected to it lower edge on the blade rear wall in the area of its transverse edge is attached and extends upwards and forwards while said rear wall extends downward from said front transverse edge and merges into a vertical section, the lower edge of which is on the rear side of the blade rear wall below and rü is attached rearward from the transverse edge thereof, and each end section has a vertical section which continues the vertical section of the central section outwards and merges into a section which extends forward.
  • the driver of the shovel loader has difficulties in observing the degree of filling of the loader bucket.
  • the known construction proves to be complex to manufacture and therefore expensive.
  • the invention has for its object to design the catch plate described above so that in addition to its usual function, it not only serves to stiffen the loader bucket in its upper edge region, but also allows the degree of filling of the loader bucket to be observed.
  • the catch plate according to the invention can be produced from a sheet metal plate, the round web provided between the above-mentioned U-legs of the central section allowing the sheet metal plate to be bent at low cost.
  • the loader shovel shown consists of two upright side walls 10, 11, between which a bottom 12 and a rear wall 13 extend. The latter protrudes upwards and forwards and ends in an upper horizontal transverse edge 14.
  • a transverse cutting edge 15 which extends over the entire front side of the loader bucket.
  • the side walls 10, 11 merge forward into vertical cutting plates 16, 17 which have sharpened front edges for penetrating into the earth or into material to be charged.
  • the catch plate consists largely of a single main plate construction 30 with a rear lower vertical section 31 which extends over the full width of the loader bucket.
  • the lower edge 32 of this vertical section 31 lies against the back of the blade rear wall 13 and is welded to it.
  • FIGS. 3 and 4 clearly show that the said edge 32 lies backwards and below the transverse edge 14 mentioned above.
  • the vertical section 31 extends upward from its lower edge 32 to connecting seams 33, 34, 35 with a U-shaped central section 36 and two end sections 37, 38 which extend outward from the opposite ends of the central section 36.
  • Figures 1, 3 and 4 show that the connecting seams 33 to 35 are approximately at the height of the said transverse edge 14 of the blade rear wall 13.
  • the middle section 36 extends across most of the blade width and has a rear wall 40 which, starting from the connecting seam 33, extends upwards and forwards to a horizontal upper circular web 41, from which the middle section 36 extends downwards and has rear wall 42, which ends in a lower horizontal edge 43 on the back of said transverse edge 14 of the blade rear wall 13, but approximately in the region of this transverse edge 14.
  • Figure 4 shows that the upper horizontal transverse edge 14 is welded against the front of the front wall 42 of the central section 36.
  • the front wall 42 lies essentially in the plane of the blade rear wall 13 and extends as a kind of continuation of this wall upwards and forwards.
  • the end sections 37, 38 consist of horizontal sections which extend from the corresponding connecting seams 34, 35 to the vertical section 31 to the front.
  • the front edges of the end sections 37, 38 end on the rear side of the blade rear wall 13 in the region of its upper transverse edge 14 and are welded to this rear side, as best shown in FIG. 3.
  • the outer edges of the two end sections 37, 38, like the rear upright wall of the vertical section 31, are welded to the side walls 10, 11.
  • the ends of the middle section 36 are inclined upwards and inwards, and filler plates 45, 46 which are adapted to the shape of their openings are each closed off to the surface of the adjoining end sections 37, 38.
  • the filler plates 45, 46 extend into an area below the end sections 37, 38 and are welded against the vertical surfaces of the vertical section 31.
  • the outer edges of the filler plates 45, 46 are welded against the inner wall of the middle section 36 and thereby reinforce the middle section and prevent its deformation.
  • the middle section 36 forms a channel-shaped construction with the upper part of the blade rear wall 13, which gives the middle section high rigidity and the deformation of which is prevented by the filler plates 45, .46.
  • the end sections 37, 38, together with the vertical section 31, form an angular iron carrier which stiffens the end sections of the blade rear wall 13.
  • the trough-shaped construction thus extends over the full width of the blade along the upper portion of the blade rear wall 13. This increases the strength of the blade significantly.
  • a pair of chain connecting plates 48, 49 or lifting plates are welded against the rear of the rear wall 40 and against the rear edges of the vertical holding ribs 20, 21.
  • the plates 48, 49 mentioned have openings in their center and a groove in the edge, which are used for receiving and fixing holding chains, which can be used for carrying or pulling out products by using the lifting arms of a loader.
  • main sheet metal structure 30 functions as a stiffener, it still adequately functions as a catch sheet, the opposite ends of which are set slightly downward, so that an operator can recognize any filling material falling out over the lower edge.
