DK151124B - ROOT FRUIT RECORDER - Google Patents

Description

The invention relates to a recording apparatus for mounting on a root fruit picker, said recording apparatus having a plurality of recording units each comprising two rearward and downwardly pointing recording wheels which, during their rotation, squeeze the root fruits out of the ground.

Such recording devices are usually used side by side when harvesting, for example, beets. When the two pickup wheels pass on either side 15 of a beet, it will be lifted off the ground and thrown backwards, for example on a conveyor belt for further processing.

From Danish Patent Specification No. 147,331, 20 such an apparatus is known in which the take-up wheels (also called the pick-up wheels) are arranged on each branch of a substantially U-shaped resilient hanger. The recorder can be adapted to different root vegetables with a stag bolt that can clamp the bracket branches more 25 or less together.

If a large stone comes in between the casters, these will simply stand still. It is then necessary to drive backwards to get the stone out.

30 Thereby, harvest time is lost, just as some beets will inevitably be lost.

Attempts to solve this problem are springy stone triggers, but these have the disadvantage that soil and in rocks can get trapped after the wheels are separated.

Therefore, the wheels will not go all the way to the working position again, so the distance between them becomes too large.

Also known are structures which use spacers to determine the minimum distance between the recording wheels. This is a slow way of adapting the recorder to the actual root fruit size 10.

The object of the invention is therefore to provide a root fruit picker without the aforementioned disadvantages, since the pickup device must be able to operate despite stones between the pickup wheels and also be easy to adjust.

This is achieved according to the invention when one take-up wheel is rotatably mounted on a supporting arm projecting from the root fruit picker, when the second take-up wheel is rotatably mounted on a pivot arm, which at its opposite end is thus rotatably mounted on the support arm, so that the distance in the horizontal plane between the take-up wheels may be varied, and when an end with the spring force axially compressible connecting arm is arranged between the end of the pivoting wheel and the support arm.

If a rock comes in between the pickup wheels, the sliding wheel on the swing arm will move out to 30 more. since. Either the stone will fall out between the wheels or it will be pulled through the wheels and thrown backwards like a beet.

Thus, it is not necessary to stop the uptake 3 151124 1 of root vegetables.

For the same reason, less force is required for the drive wheels to rotate solely due to ground 5 friction.

It is convenient if the recording apparatus is configured as claimed in claim 2, wherein the pivot arm facing away from the wheel is pivotally mounted to the support arm at its side facing the other wheel, the pivot axis of the pivot arm substantially extending perpendicular to the support arm, and wherein the end of the connecting arm away from the wheel is horizontally pivotally mounted to the opposite of the support arm.

The longitudinal side, that is, the side facing the wheel, since this construction has proven to work very well in practice while being relatively simple to manufacture.

If the connecting arm as claimed in claim 3 is a hydraulic cylinder connected to a pressure accumulator, it is achieved that the wheels of the cylinder will be pressed against each other. Thus, when the sliding wheel has moved aside for a rock, the recording wheels will move 25 by themselves and easily return to the starting position.

It is expedient if the recording apparatus as claimed in claim 4 has a stop, thereby simply determining a well-defined minimum distance between the recording wheels.

If the stop as claimed in claim 5 consists of a screw or the like arranged in one arm, and the other arm has a stop plate for abutment against the screw in the stop position, it is achieved that the distance between the wheels can be adjusted very much. single. The connecting arm will always make sure that the pickup wheels 5 are pressed together against the stop, so that the desired distance can be adjusted simply by adjusting the screw.

Finally, a compact and solid construction is obtained if the recording apparatus is designed as claimed in claim 10 6.

The invention will now be described in more detail with reference to the drawing, in which: FIG. 1 is a longitudinal section through a recording aperture according to the invention; FIG. 2 is a top plan view of the recording apparatus in the direction of the arrows along line I-I of FIG. 1, and FIG. 3 shows the take-up wheel in the same way as in FIG. 2, the movement of the sliding wheel is shown punctured.

25 In FIG. 1 shows how a support arm 5 is attached to the root fruit boom 1 with connecting parts 2, 3, 4. The displaceable wheel 17 is provided with a shaft 15 on a swing arm 12. The swing arm 12 consists of two parts which are parallel and enclose the support arm 5, the pivot arm 12 being pivotally mounted to the support arm 5 by a hinge 6. All parts of the recording apparatus are preferably made of metal, iron-free.

To the inside of the support arm 5 having a U-shaped cross-section # is a hydraulic cylinder 13 mounted with a hinge 11.

5 At the opposite end, the cylinder 13 is connected to the shaft 15 of the sliding wheel 17 by a hinge 14.

Finally, there is seen a stop plate 16 which together with the screw 9 9 determines the minimum distance between the take-up wheels 10, 17.

The hydraulic cylinder 13 communicates with a pressure accumulator not shown, the function of which is to be elaborated on in greater detail in the following.

FIG. 2 and 3 show how the sliding wheel 17 can move with respect to the fixed wheel 10.

It will be seen that the hinges 6, 11 are disposed on opposite sides of the support arm 5, so that the hinge 6 lies on the side of the support arm 5 facing the fixed wheel 10.

The operation is as follows. If a stone enters terminal 25 between the take-up wheels 10, 17, these will be pressed away from each other, thereby compressing the cylinder 13.

Therefore, when the stone either falls out or is thrown backwards as a beet, the cylinder 13 together with the pressure accumulator will return the wheels to the original position without interrupting the harvest.

The adjusting screw 9 is arranged in a threaded portion 8 in connection with the fixed wheel 10. By screwing the screw 9 in or out of the part 8, the stop point in relation to 6 can be changed to the stop plate 16 on the moving wheel 17.

Due to the pressure of the hydraulic cylinder 13, this simple mechanism is sufficient to adjust the uptake apparatus for all sizes of root vegetables.

Finally, it can be added that the fixed wheel 10, like the displaceable one, is mounted around an axis 7 attached to the support arm 5.

It should be noted that the recording apparatus according to the invention can of course be designed in many ways other than that shown in the drawing. Thus, the device's. geometry to be substantially different without departing from the idea of the invention, if only the idea of the one pickup wheel mounted on a pivot arm is retained. In addition, it should be added that a root fruit recorder will normally be provided with several recording apparatus ^ a ^ brought in a row.
