Description

The invention relates to a device intended for plowing and hoeing in row crops, which is primarily is intended for viticulture and as a trailer or attachment device for single and two-axle tractors should be used.

There are vineyard plows that usually cover the entire strip of earth between two adjacent rows of vines Plow over in one operation and for this purpose provided with several adjacent shares are. Half of the earth is plowed up on both sides by the flocks. The one here the resulting central furrow has an unfavorable effect as a water channel. To get the roots of the vine during the To protect against freezing in winter, it is customary to plow soil on the rows of vines in autumn. This is usually done with a single-row ridging plow, which is also used in spring plows the accumulated earth from the rows of vines again. For loosening the soil between the Rows of vines are used hoes with revolving hoeing tools operated by a tractor and the distance in their working width can correspond between adjacent rows of vines.

It is known to use machines for agricultural work that simultaneously plow and chop. It has been suggested that a motor plow should have a hoe between the Track of the plow-working hoeing tools pulls the ploughshares directly in front of the drive wheels of the To arrange the plow in such a way that they plow the earth from both sides inwards between the ploughshare, where it is loosened and spread out again by the following hoeing tools. This is supposed to be achieved that the plow with its drive wheels on the furrow soles exposed by the plow bodies runs. In another agricultural working machine for deep cultivation, it has been proposed that to attach a plow that lifts the plow to a tiller, with the rotating Hoeing tools dig up the furrow floor behind the ploughshare. In one case is the work area the hoeing tools to the track width of the tractor, in the other case to the width of the from Plow body restricted to exposed furrow sole.

The invention is directed to providing a hoe equipped with plow bodies, which the in The work of plowing and plowing the vineyards and similar row crops to be done Earth to protect and expose the rows of vines or the like. Is adapted and designed so that this work with one device for two adjacent rows in conjunction with a loosening of the intermediate one At the same time

can. The device according to the invention consists of a rotating hoe and arranged in front of it on both sides Plow bodies. The invention is characterized in that the device as a trailer device for Tractor is designed, its plow body, offset to the chopping tools to the outside, immediately in front the hoeing tools working between the plow furrows and at their distance from one another are adapted to the distance between adjacent rows of vines. Preferably they are Plow body on a cross member that runs parallel to the chopping shaft and is arranged close to the chopping tools attached so that they are in their distance from each other, in the plowing depth and in terms of The cutting angle can be adjusted in a manner known per se.

In order to be able to change the working depth of the hoe independently of the working depth of the plow body expediently the cross member to which the plow bodies are attached, between the plow bodies with adjustable height Provide support rollers.

Such a device thus performs several work devices at the same time, not only in an in a well-known way, as in the case of the previously known machines, plowing and chopping are carried out at the same time, but plowing and plowing the earth in two adjacent rows is also carried out at the same time, and In contrast to the previously known machines, the ploughshares are usually far outside the track of the tractor, which should not run with its drive wheels in the area of the plow furrows and may, because this would destroy the roots of the vine.

Should the device be used for two-axle tractors with a hydraulic lifting device are provided for lifting the work tools,

so it expediently has an extendable cardan shaft which is connected to the tractor shaft by a breakaway coupling which automatically disengages when the implement is swiveled up and lifted out. Furthermore, the chopping machine and hood can be easily detached from the cross member carrying the plow body so that chopping and plowing can be carried out when necessary, e.g. B. in steeply sloping terrain, can also be done separately. The drawing shows examples of the implementation of the vineyard hoe according to the invention, namely Fig. 1 and 2 show the side view and the plan of a two-wheel tractor with attached vineyard hoe, Fig. 3 the .schaubildliche view of a vineyard hoe attached to a two-axle tractor and Fig. 4 a Detail of this version. The single-axle tractor according to FIGS. 1 and 2 is provided with an attached hoe whose tools 2 rotating in a housing 1 are driven by a longitudinal shaft 3 from the power take-off shaft 4 of the single-axle tractor. The hoe extends over the full width of the strip of earth between two adjacent rows of vines in a vineyard. On the frame 5 of the hoe a cross member 6 is arranged in the direction of travel in front of the chopping tools 2, at each of the ends of which a ploughshare 7, T is attached. The plowshares are adjustable in height with their share holders 8 on longitudinal members 9 in the direction of arrows 10. They are also adjustable with their longitudinal beams 9 along the cross member 6 in their distance from one another in the direction of the arrows 12, that is, in their width. Each of the longitudinal members 9 is assigned a crank mechanism 13 with which the longitudinal members 9, which are pivotably mounted at their rear ends, can be pivoted on the cross member 6 in order to adjust the cutting angle. The coulter holder 8 are each provided with a support roller 14, the holder of which is adjustable on the row of holes in a curved piece 15 so that the support rollers can follow the height adjustments of the shares. The shares 7, T work in opposite directions. In Fig. 2 they are in that working position in which they overturn the earth for plowing to the vine roots when driving the tractor to the outside. If the earth is to be plowed again in spring, the share holders are repositioned so that both shares throw the soil inwards. In the embodiment according to FIG. 3, the hoe 16, which is directed in its working width to the distance between adjacent rows of vines, is attached to the rear end of a two-axle tractor 17. Here, too, the hoe 16 is provided with a cross-member 19 arranged in front of the hoeing tools 18 in the direction of travel, at the ends of which a plow body 7 or T is attached. Between the plow bodies 7, T, support rollers 22 are arranged, the holders 23 of which, like the share holders 24, are each adjustable in height in a bearing head 25 with an associated crank mechanism 26. In addition, along the cross member 19, the plow bodies with the bearing heads 25 can be adjusted in width to different distances from one another. To adjust the cutting angle, the chopping frame 4 can be pivoted into different positions with the aid of the lifting gear of the two-axle tractor. The chopping tools are driven here by the power take-off shaft 27 of the two-axle tractor via a cardan shaft 28. B. for road travel, can be pivoted upwards by steep excavation, a breakaway coupling 29 is switched on in the shaft assembly 27, 28, which enables a kink angle of the shaft assembly over 45 ° in every position of the joints 30, 31. In this case, as can be seen from FIG. 4, the coupling members of the breakaway coupling disengage. In some layers it can happen that the pulling force of the single or two-axle tractor is not sufficient to carry out the chopping as well as plowing or plowing in one ao operation. For this purpose, the chopping mechanism is designed to be separable from the plow frame by means of a quick-release fastener, so that the device can be used both as a pure hoe, also for field cultivation, and as a pure plowing or plowing device.
