The swinging frame holder is further engaged with a working linear motor anchored to the body.

Description

Spreader of semi-solid, pulpy, pulverulent materials, eg manure, sugar sludge etc.

A spreader having a driven sliding bottom and spreading members arranged on its discharge side, on which an adjustable closing wall is arranged and at least one horizontal distributor cylinder has a closing wall mounted on a pivoted frame holder provided with a stop and supported by a pin on the body brackets. it is provided with at least one guide for the closing wall. Furthermore, the pivoting frame bracket engages a working linear motor anchored to the body.

The invention relates to a spreader of semi-solid, slurry, powdered materials, for example manure, sugar sludge and the like, with a driven sliding bottom and spreading organs arranged on its discharge side, on which the adjustable closing wall is arranged, or behind it. at least one horizontal distributor roll.

Spreaders of this type are well known and appreciated in practice for their reliability and relatively wide application. In addition to the spreading function, the closing wall allows their use for purely transport purposes.

The existing arrangement of the closure wall, however, has a certain disadvantage in that its tilting from the closure to the reflection position and, conversely, imposes increased demands on the operator of the spreader, further in that it limits the cleavage. the degree of filling of the spreader and does not allow sufficient closure of the closure wall, which in some applications limits the performance of the machine.

It is an object of the invention to overcome these drawbacks.

SUMMARY OF THE INVENTION The closure wall is mounted on a pivoting frame bracket provided with a stop and supported by a pin on the body brackets provided with at least one guide for the closure wall, the pivoting frame bracket engaging a working linear motor.

Structurally and functionally, it is preferred that the pivoting frame bracket consists of upper beams and struts connected to each other at the pivot side directly and at the opposite end by means of stops for the closing wall, which is provided with guide rails.

Furthermore, it is advantageous for the pin axis to be arranged above the spreading rotors outside the opening cylinder, thereby achieving a large range of movement of the closing tent by means of a working linear motor without the need for any other adjustment. The movement of the closing tent is determined and limited either by guides or stops so that it is always outside the opening cylinder.

An exemplary embodiment of the invention is described below with reference to the accompanying diagrammatic drawings, in which Fig. 1 shows the rear part of the spreader in a side view with the closure tab raised; Fig. 2 also the rear part of the spreader in a side view but with the closure in spreader spreader.

The spreader body 1, provided with the traveling wheels 2, is connected in a known manner to a towing tractor, the PTO of which, via the corresponding, also known means - a PTO shaft, gearboxes, etc. - has the necessary driving force of the sliding floor 3. as well as the spreading rotors 4 arranged above the uncoiling table 5, respectively. and the horizontal spreader roll 6.

Brackets 7 are fastened to the body 1 on its discharge side, on which a pivoting frame holder 9 is formed by pivoting means 8, formed by upper beams 91, one end of which is connected to struts 92; the other ends of the beams 91 and the struts 92 are connected by stops 93 having the form of support rails on which the closure wall 94 of the hull 2 is supported ^{in its} raised position, as shown in Fig. 1.

The body 1 is further provided with at least one guide 95, in this case two, on which, in part of its upper position and during movement in the lower position, the closure wall 94 is supported and guided by the skids 96.

The pivoting frame holder 9 and the closure wall 94 are arranged such that at any stage of their movement they are out of the reach of the horizontal opening cylinder 6 when it is used. An imaginary vertical plane through which the pivot axis 90 of the pivot bracket 9 passes also extends through the spreading rotors 4, but lies outside the horizontal opening cylinder 6.

At least one working linear motor 10 for adjusting and controlling its position is provided between the pivot frame holder 9 and the body 1; this may consist, for example, of a known hydraulic working cylinder, possibly also of conventional mechanical means for adjusting and securing the position.

Giant. 2 shows the spreader e with the closing wall 94 in the lower position, whereby the closing wall 94 rests with its lower edge to the sliding bottom 3 and thus closes the body 1 tightly, for example during the transport of semi-liquid slurry or pulverulent masses. The position of the closure wall 94 is defined by guides 95.

When spreading is required, the closure wall 94 is raised to the desired height by means of said working linear motor 10 and the substrate from the container 1 to be spread is passed through a gap between the movable sliding bottom 3 and the lower edge of the closure wall 94 - i.e. After being hit by the spreading rotors 4, the substrate is unwound into the field while the spreader is traveling.

The pressure exerted by the substrate on the sidewalls of the body 2 also acts on the closure wall 94 and is transmitted by the skids 96 to the guides 95, preventing the closure wall 94 from swinging to the horizontal spacing of the cylinder 6.

Upon further lifting of the closure wall 94 by the working linear motor 10, the closure wall 94 begins to deflect, supported by the skids 96 on the guides 95 according to their shape until it leaves, and then begins to rest against the stop 93 as shown in FIG.

Said solution allows a reliable, controllable movement of the closure wall 94 without the need for its tilting and without the risk of collision with the horizontal spreading roller 6.
