Description

The present invention relates to a soil working machine, in particular for asparagus growing.

Asparagus fields, which are characterized by relatively high rows of dams, were so far prepared or further processed that the loosened earth by human hands to the well-known trapezoidal Rows of dams was raised.

This type of field preparation was very time-consuming, apart from the fact that large ones Fields a lot of labor were needed. Also, by editing with Shovel and other common tools a uniform and thorough Processing of the fields very questionable.

The new soil tillage machine guarantees fast, safe, thorough

ao and even cultivation or production of the asparagus fields. It represents the union a tiller with adjustable profile flaps, the tiller the work of loosening the soil for

»5 asparagus growing plays a special role, while the profile flaps the Form asparagus ridges. Since there are asparagus banks of different widths, the profile flaps are pivotable and adjustable against each other with the help of levers. Special ones on the lower edges of the profile strip flaps and the side protection walls of the machine enable edge strips arranged a further profile adjustment and furthermore, by replacing it, a replacement of damaged strip parts. In front of the milling machine a cutting device is arranged, which protrudes into the earth and the old stems of the Cutting off asparagus plants, as these wood stumps are easily injured when pricking asparagus the fingers caused. To the soil profile of the valley floor between the asparagus dams a furrow opener is provided on the side of a profile strip flap. The whole tillage machine is pulled either by one of the known tractors, with a cardan shaft of the tractor drives the tiller, or the machine has its own motor drive.

The invention is shown in the drawing, namely show:

Fig. Ι the asparagus tillage machine in partial longitudinal section AB according to Fig. 2, for example designed as a device to be pulled by a towing machine,

Fig. 2 the machine in plan view,

Fig. 3 the machine in the view from the rear,

Fig. 4 is a vertical section through the cutter axis with a pair of cutters attached,

Fig. 5 the cutter axis in section CD according to Fig. 4,

Fig. 6 the asparagus field profile achieved by processing with the machine.

The milling tools 2 are seated on the shaft 1 mounted on both sides of the machine.

The wave ι is made by chains ο. like drive 3 set in rotation, with the interposition of comb wheels 4 o. is driven by a cardan o. The like. Shaft 5, which is driven by the engine of the tractor 6 is also driven. A cutting device 7 is located at a suitable location in front of the milling cutter shaft in relation to the direction of travel arranged, which has the purpose of removing what is still in the field from the ground Cut off protruding weeds to prevent the milling tools from getting caught avoid. In this case there are two cutting knives 8 and 9 which are formed at an acute angle staggered (Fig. 1, 2 and 3) to prevent the herb from sticking to the Prevent cutting device. Around the milled ground into trapezoidal rows of hills (Fig. 6), the adjustable flaps are behind the actual milling machine 10 and ι χ arranged. To determine the exact shape of the trapezoidal rows of hills are the flaps 10 and 11 about the points 12 and 13 pivotally mounted so that with the help of each other inevitably arranged intermediate organs 14 and 15 fold the Streif can be adjusted according to the hill profile. The pages that touch the earth the grazing organs are expediently designed as exchangeable organs 16 or 17, they are still arranged so that they too have an adjustment with respect to the profile allow. So that the valley floors of the asparagus field also have a clean profile for the purpose Experienced inspection of the field is still on the side of the tillage machine a corresponding profiled angle coulter 18 arranged interchangeably. The whole device moves on to the cranked axle 19, which is pivotally mounted at 20 and 21, respectively is arranged wheels.

To the machine on the country road or

To make it mobile when turning, the cranked axle 19 is carried out in a known manner

Lever or the like, in this case by driving the worm 22, which is controlled by a handwheel 23 O. The like. Is set in action, pivoted so that "the running wheels 31 on the ground come and the whole device is lifted. To firmly connect the milling tools 2 (Fig. 4) to the milling cutter shaft 1, these are designed so that the bracket 24 and 25 alternately in combination two milling tools offset from one another overlap the shaft. To fasten the connecting bolts 26 or 27 (Fig. 4 and 5) are the Pipe bushings 28 and 29 fixedly arranged on the cutter shaft. As a result of the division of a 60 Milling tool in three almost equivalent parts can break, usually only one Part is destroyed, the whole milling tool by replacing the broken part again to be completed. Suffered z. B. the actual milling tool 2 break, then can it is easily removed by loosening the screw 30 and the replacement piece is quickly attached will.

Claims (2)

Patent claims: 1. Soil tillage machine, especially for growing asparagus, marked by combining a tiller (1, 2) with in the direction of travel arranged behind this and forming extensions of their side protection walls, pivoting profile flaps. (10, 11), at their rear ends Attack the adjusting lever (14, 15) by means of what the angle formed by the flaps and thus the shape of the asparagus ridge they produce can be changed. 2. Soil cultivating machine according to claim i, characterized in that before the tiller has a cutting device (7, 8, 9) and to the side of one of the profile strip flaps a furrow opener (18) is provided. 1 sheet of drawings
