DE2343597A1 - Fertilizer spreader with portable chassis - has hopper with distributor pipe connected to its open base and drive mechanism - Google Patents

Abstract

The distributor pipe is connected to the hopper by means of a hollow, conical piece connected to the open base of the hopper. The drive mechanism converts the rotary motion coming from the driving shaft of the tractor, into a to-and-fro oscillating movement of the hollow conical part and of the distributor pipe. A counter-weight is positioned diametrically to the distributor pipe in relation to an oscillating shaft. The centre of gravity of the oscillating parts is situated on or near the vertical line passing through the centre of gravity of the whole machine.

Patent application S t reu ν or r i gt un g

The invention relates to a scattering device for a to be distributed Material, e.g. for a fertilizer, containing a portable or otherwise portable storage container supporting frame, a drive mechanism and a manifold pipe connected to the open bottom of the reservoir, which is set in a reciprocating oscillating motion by the drive mechanism.

There has been a growing need for spreading in agriculture of a material over a large floor area, spreading devices with longer distribution pipes and faster drive produced. But all of this has an unsteady

ge mode of operation of the spreader and therefore wurae tries to balance the distribution mechanism to such an extent that such an unsteady mode of operation is avoided. But in the known balanced spreading devices in which, for example, a counterweight with the same Frequency, but is moved back and forth in the opposite sense, the measures to achieve a mass balance have to very complicated constructions.

It is the object of the present invention to provide a balanced working spreading device with a simple structure, with which the material to be distributed can be scattered over a large floor area.

To this end, the invention proposes that in a spreading device of the type described above, relative to the axis of the pivoting movement a counterweight is arranged diametrically to the distributor pipe.

The invention is based on the recognition of the fact that it is not necessary to balance the entire device, i.e. not avoiding any transfer of inertial forces to the wagon or tractor carrying the spreading device got to. If only a pure torque remains as a mass reaction, this torque can easily, e.g. through the lifting rods the three-point linkage of the tractor absorbs grounding without the spreading device swinging sideways. One The vibration caused by the inertial forces exerted in the horizontal plane of the frame is the cause of the troublesome Operation of unbalanced or poorly balanced spreading devices.

In the case of a spreading device with one symmetrical to two vertical, Storage containers lying on each other at vertical levels, the counterweight is expediently dimensioned and arranged in such a way that

that the center of gravity of the manifold with the material to be distributed and the counterweight in it Kittelllage on the center of gravity of the whole spreading device continuous vertical straight lines. With such a symmetrical storage container, the center of gravity shifts his lape on the side while emptying the storage container.

If, on the other hand, a storage container has any shape, the center of gravity of the counterweight and the distribution pipe is expediently located ir. with the material contained therein for distribution the vertical straight line passing through the center of gravity of the entire spreader device when the storage container is only slightly is filled.

U.N; to facilitate the mass balancing of any spreading device and they can be adapted to the material to be spread at least one part in one embodiment of the invention of the kitchen weight can be exchanged while it is in different Distances from the axis of oscillation can be adjusted.

The following are two embodiments of the invention below Described with reference to the accompanying drawings.

1, 2 and 3 show the side view, a detailed view and the top view of this detail of a spreading device according to the invention with a stationary counterweight and

Figs. U and 5 show the side view and the bottom view such a spreading device with an adjustable counterweight.

The spreading device shown in the figures consists of a frame 1, a storage container 2, a drive mechanism 3 and a distribution pipe 5, which is connected to the open bottom of the storage container via a hollow, conical body U is. The drive mechanism 3 converts one of the output shaft of an agricultural tractor, of which only the rear wheel 6 is shown, removed rotational movement into a reciprocating swinging movement of the hollow, conical body 4 and the distributor pipe 5. The hollow one conical body is with an oscillating shaft mounted in the frame 1 7 connected.

According to the invention, a counterweight 8 is arranged relative to the oscillating shaft 7 diametrically to the distributor pipe 5 and is dimensioned in this way is that the center of gravity of the vibrating parts is on or near that passing through the center of gravity of the entire arrangement vertical straight line. In the embodiment shown in FIGS. 1-3, there is always a counterweight on the conical body U fixed to an invariable size. This embodiment is therefore only for one particular type of dispensable material or for a given output, i.e. suitable for a given amount of material spread on the field.

Because the going through the center of gravity of the entire spreader vertical straight line does not necessarily have to coincide with the center line of the oscillating shaft 7, can only be in a single one Position the center of gravity of the counterweight and the distribution pipe with the material contained therein on the said vertical Lie straight. This position of the distributor pipe corresponds to the central position of the distributor pipe during its oscillations in Devices constructed symmetrically to the median longitudinal median plane.

4 and 5 show a modified construction of the counterweight 8. In this embodiment, the counterweight is on the

50981 1/0113

elongated, lower free end of the oscillating shaft 7 attached. The counterweight is in the form of a rod 9 on which the movable body Io is held by two screw nuts 11 will. Of course, the body Io can be replaced by several bodies of different weights, especially. Therefore enables this embodiment, the rapid adaptation of the spreading device to any material to be distributed.
