Definitions
- the invention relates to a device for displacing material, such as mud, comprising a frame.
- Such a device is used for instance in dredging brooklets, ditches, canals and the like.
- the discharge of mud is a problem.
- the device is characterized in that the frame supports a driven rotor, to which at least one scoop is fixed, the scoop scooping material in the lower part of its path and thereupon throwing it away.
- Fig. 1 is a front view of an embodiment of the device according to the invention.
- Fig. 2 shows a part of the front view of fig. 1 wherein, however, the device is shown in another position.
- Fig. 3 is a front view of a second embodiment of the device according to the invention.
- Fig. 4 is a front view corresponding to fig. 3, wherein, however, the device is shown in another position.
- corresponding parts are indicated with the same reference numerals.
- the drawing shows two embodiments of a device according to the invention, which are in particular suitable for dredging brooklets, ditches, canals and the like.
- the frame of this device of which a transverse beam 1 is shown in the drawing, may be coupled to every desired vehicle or vessel.
- the direction of movement is substantially perpendicular to the plane of the drawing.
- a barge 2 is mounted to the transverse beam 1 of the frame by means of bolts, the barge related to the direction of movement, being open at the front side and being provided with a rear wall 3 at the rear side, the rear wall preferably having openings therein.
- a rotor 6 is connected to the transverse beam 1 , said rotor may be driven by a driving means, such as an internal combustion or a hydraulic engine (not shown) .
- a driving means such as an internal combustion or a hydraulic engine (not shown) .
- On the rotor 6 four spoon like means 5 are provided, the spoon like means 5 extending radially and being equally spaced in circumferential direction, and each spoon like means 5 consists of a metal arm 7 with a scoop 8 provided at the end thereof.
- These scoops 8 are preferably perforated, or may be made of wire netting or such material. Consequently the liquid taken along during a scoping movement can already drain off at least partially prior to throwing away the contents of the respective scoop 8.
- the device according to fig. 1 or 2 comprises a lever 9, which is pivotally adjustable about a pivot shaft, which is co-axially aligned with the axis of rotation of the rotor 6.
- the position of the lever 9 is adjustable by means of a cylinder-plunger assembly 10, which on one hand is connected to the lever 9 and on the other hand to the trans- verse beam 1.
- a leaf spring 11 is hingedly mounted on the lever 9, which leaf spring partially extends in extension of the lever 9.
- Two transverse pins 12 at the end of the lever 9 on either side of the leaf spring 11 serve for supporting the leaf spring 11, when it is loaded.
- the end of the leaf spring 11 carries an enlarged head 13.
- a laterally projecting cam 14 is provided at the respective side of the scoop 8, the cam being adapted to engage the leaf spring 11.
- the spoon like means 5 can be rotated about their longitudinal axis by means of a cylinder-plunger assembly 15, a lever 16 and a rotation mechanism operatively engaged by the lever 16, so that when the spoon like means are rotated through 180° and the direction of rotation of the rotor 6 is reversed, the device can operate in the reversed sense.
- the rotation mechanism for the spoon like means 5 can for instance consist of a pinion wheel provided at the inner end of each arm 7, the pinion wheel being in engagement with a crown wheel, which is rotatable by means of the lever 16.
- Another way to enable a reversed operation is to provide the spoon like means with two scoops facing away from each other, so that in this case it is only necessary to chang the direction of rotation of the rotor. It is also possible to provide an operation of the device in the reversed sense by rotating the transverse beam 1 together with the rotor 6 fixed thereto through 180° about a vertical axis.
- a spring member may engage each spoon like means, of which the arm is pivotally connected to the rotor by means of a pivot shaft extending parallel to the axis of rotation of the rotor.
- a retaining member may engage each spoon like means in a part of its path.
- the arm of the spoon like means may be of a rigid construction and the arm is tensioned by its pivoting movement against the spring force of the spring member.
- the device according to the invention works as follows:
- the leaf spring 11 and the arm 7 will bend to a certain degree dependent on the stiffness thereof.
- the leaf spring 11 will bend to such an extent, that the cam 14 of the scoop 8 moves along the leaf spring 11 to the end thereof, where the cam 14 temporarily catches in behind the enlarged head 13 of the leaf spring 11.
- the cam 14 will suddenly release from the enlarged head 13, in consequence whereof the arm 7 forcibly returns to the non-deformed state, in such a way that the mud dredgings 4 in the scoop 8 are thrown away as a coherent clot (dotted in fig. 2) .
- the inclination, with which the mud dredgings clots are thrown away, is adjustable by means of an adjustment of the position of the lever 9, consequently the distance along which the dredgings are thrown away can be changed.
- the position of the lever 9 has to be adjusted also, when the direction of the rotor 6 is reversed. In this case the lever can be placed in the position shown in dotted lines in fig. 1. As circumstances may require mud dredgings clots may be thrown onto the surrounding terrain, or may be thrown into a collecting container connected to the vehicle or vessel of the device.
- the barge 2 of the device also serves as a temporary storage of the mud to be removed.
- the rotor 6 may be stopped temporarily, and only the device with the barge 2 may be moved.
- the driving of the rotor 6 can be started again and the mud dredgings collected in the barge 2 can be scooped out and thrown away.
- the rotor 6 does not have to rotate at high revolutions per minute.
- the speed of revolutions of the rotor 6 is preferably between 5 to 50rpm.
- a slowly rotating rotor 6 has the advantage, that there is only a very small chance, that the scoops 8 will be damaged by large and hard objects possibly present in the mud.
- Fig. 3 and 4 show a second embodiment, in which the leaf spring 11 of the first embodiment is replaced by an adjustable spring mechanism 17.
- This spring mechanism 17 comprises a sickle-shaped member 18, which is hingedly connected to the lever 9 by means of a horizontal pivot shaft 19.
- the curved ends 20 of the sickle-shaped member 18 serve as engagement points for the cams 14 of the scoops 8.
- an arm 21 mounted hereto is connected to a transverse arm 22 of the lever 9 by means of a cylinder- plunger assembly 23.
- Fig. 4 illustrates the position of the sickle- shaped member 18, in which the cam 14 of the scoop 8 just comes into contact with the sickle-shaped member 18 (on the left during a clockwise rotation of the rotor 6, on the right during a counter-clockwise rotation of the rotor 6) .
- the arm 7 of the spoon like means 5 is bent the cylinder-plunger assembly 22 will be compressed, so that the sickle-shaped member 18 will be turned to such an extent, that the cam 14 on the scoop 8 will release from behind the end 20 of the sickle-shaped member 18 and the arm 17 will forcibly spring back to the non-deformed state.
- the device in displacing heaps of coals or beets and the like, while the device can be put on a lot of other applications.

Abstract
Dispositif comprenant un rotor entraîné, pourvu d'un certain nombre d'organes en forme de cuillère (5). Chaque organe en forme de cuillère comprend un godet (8) fixé à l'extrémité d'un bras. Un mécanisme permet d'accélérer chaque organe en forme de cuillère sur une partie de son cheminement. Pendant le fonctionnement du dispositif chaque godet ramasse la matière dans la partie inférieure de son cheminement. Le godet est ensuite accéléré dans la partie suivante de son cheminement de manière à projeter la matière présente dans le godet.Device comprising a driven rotor, provided with a number of spoon-shaped members (5). Each spoon-shaped member includes a cup (8) attached to the end of an arm. A mechanism makes it possible to accelerate each spoon-shaped organ over part of its path. During the operation of the device, each bucket collects the material in the lower part of its path. The bucket is then accelerated in the next part of its path so as to project the material present in the bucket.
