Definitions

  • the invention relates to a belt conveyor for truck mixer according to the preamble of Claim 1.
  • Belt conveyors are used for introducing materials such as concrete, sand, split or Rolling used by a truck mixer in the construction site.
  • the transport from Concrete plant to the construction site must be handled quickly and economically.
  • This one is capable of that Transport goods from the truck mixer at a certain point on the construction site too promote.
  • belt conveyors which are articulated with each other from three consist of connected rigid elements. About piston cylinder arrangements can pivoted the corresponding elements around the joints against each other become.
  • the elements of the belt conveyor are folded together in a transport position, that they are beyond the outer contour of the vehicle in the front area, ie do not protrude above the driver's cab. In the working position they take one comparatively slightly inclined position, so that the goods to be transported pass over the Conveyor belts can be transported.
  • a belt conveyor has become known in which of the three elements forming the belt conveyor just the last element on which a discharge hopper or a discharge chute is arranged, telescopic is.
  • the advantage is seen in that the belt conveyor on a construction site can also extend through a narrow window, which is on another Height than the truck mixer is because the joint between the second and third Element can be arranged just in the window opening.
  • this known embodiment for example, in the case of conveying the Transport good in a building with appropriate pivoting of the last Element compared to the second element of the belt conveyor a comparatively large angle of 30 ° and more taken. So here's an abrupt transition formed by the oblique to horizontal conveying the cargo. at Such a strong kinking of the conveyor belt occurs in the promotion of usually conveyed cargo, such as concrete, undesirable Segregations. To prevent this, the conveying speed must be the belt conveyor are significantly reduced.
  • the object of the invention is therefore, according to a generic belt conveyor further develop the preamble of claim 1 such that the belt speed can be increased during transport of the cargo without a Demixing of the material takes place at the Abknickddling.
  • this object is achieved by the combination of the features of Claim 1 solved. Accordingly, a generic belt conveyor of four Elements composed of which the second and / or third element telescopic is, while the last element in its length is not changeable. Due to the provision of the four elements can in the end of the belt conveyor two break points are created, which make a transition from the oblique to the Horizontal conveying of the cargo to make much gentler. Thereby The tape speed can be increased without skipping Material takes place at the break point. An unwanted separation of concrete or another cargo is safely prevented. Also the rollers and conveyor belts are spared in the area of the breakpoints formed here.
  • Another advantage of the invention is that, if desired, the maximum possible delivery height can be increased, since the last break point near the End of the band is located.
  • both telescopes can be used for the maximum head become.
  • the comparatively short trained fourth non-telescopic Element bent relatively stronger. In this special case in which it depends on a high head, but on request, the conveying speed reduced to prevent the segregation of the cargo become.
  • a further preferred embodiment of the invention is that the belt conveyor is rotatably mounted on a platform and that the platform to the vehicle chassis can be decoupled to or from this.
  • Fig. 1 denotes a construction conventional truck mixer, in which on a Vehicle chassis 12, a mixing device 14 is constructed with mixing drum. At the vehicle chassis 12 is coupled to a platform 16 on which a belt conveyor 18 is arranged vertically pivotable.
  • the swivel system is not closer shown. It consists in the embodiment shown here of a ball slewing connection.
  • the rotary actuator allows a swivel range of 240 °.
  • the belt conveyor consists essentially of four individual elements, namely the first element 20, the second element 22, the third element 23 and the last and fourth element 24.
  • the individual elements are about piston-cylinder arrangements 26, 28, 30 and 32 against each other about pivot points 34, 36 and 38th pivotable.
  • the second element 22 and the third element 23 are each telescopic, as is apparent from Fig. 1, in which these elements in austeleskopierter Position shown results.
  • the second element 22 is shown here Embodiment, a four-meter-long telescope, while the third element 23rd is a one meter long telescope.
  • the fourth element which is a dispensing funnel 40 for the cargo, so for example, the concrete has, is relatively short and is not adjustable in length.
  • On the elements 20, 22, 23 and 24 of the transport conveyor 18 drivable conveyor belts are mounted, via which transport goods from a discharge chute 42 of the truck mixer 10 to Abgabetrichters 40 at the end of the fourth element 24 is conveyed.
  • the third element 23 is in the embodiment, as shown here in Fig. 2 is, telescoped out.
  • the transport belt not shown here is about in their construction known and not shown here in detail Tensioning devices when retracting the telescope held under tension. The the same applies to the conveyor belt of austeleskopierbaren second element 22nd
  • the angle ⁇ at the pivot point 36 is in Fig. 2 15 °.
  • Fig. 2 are two others Positions of the transport conveyor 18 shown.
  • the angle ⁇ (corresponding to Fig. 4) is larger - in the illustrated embodiment 30 °.
  • Around to avoid segregation here is a slower transport speed of the goods transported. But can be a difference in height of .DELTA.h of be overcome over a meter in addition.
