DE4113191C2 - Universal plow body shape that can be adjusted using the angle of rotation and lateral direction with an endless self-rotating band instead of the conventional mouldboard - Google Patents

Description

The invention relates to a plow body according to the preamble of claim 1.

Such a plow body is known from CH 119 161. There it is not possible to fix the rollers, the rotation direction angle or the side direction angle change. The direction of rotation is through the prank sheet metal front part, which is already a third of the The size of a normal mouldboard. So it will be at the known construction only about two thirds of the body form formed by a band, due to its three straight continuous rolls only a slight direction of rotation has angle. Thus, the plow body from the CH 119 161 only achieved a slightly improved use of tractive force. From US 43 19 645 it is known with a plow body Mouldboard a hydraulic adjustment of the side straightener angle. An angle of rotation adjustment is not possible due to the construction there.

Based on the state of the art according to CH 119 161 Invention based on the task for a plow body Kind of an optimal setting depending on the condition of the soil and the working conditions fen.  

This task is characterized by the characteristics of the contractor spell 1 solved.

In the plow body according to the invention, the arrangement the two front and two rear pulleys and the um running tape has already reached the optimal body shape.

By largely replacing the mouldboard with the running belt, the loss of frictional force is kept to a minimum reduced. The arrangement of the rotatable bearings in the support frame and in the stabilizing frame does it by hand Hydraulic cylinders possible, the lateral direction and to adjust the angle of rotation. So one is always optimal body shape with different types of soil, Soil conditions and the respective local conditions possible.

For example, when the floor becomes heavy or tillage direction from the slope towards the plain rare and / or if there is a change in the direction of the slope down follows, for example when plowing down the slope Lateral angle and the direction of rotation ent speaking openly, with reverse conditions demented speaking the side and direction of rotation more closed sen. So it is now possible that in heavy soils desired plow depth can be maintained and not how so far that the plow rises in heavy soils and on light soils, the plow works deeper than desired and brings the dead earth up. It also prevents being attached to the rear pulleys brought scraper stick to very sticky soils.  

To ensure an optimal tension of the belt, be there is one on the support frame and on the stabilization frame telescopic clamping device.

An embodiment of the invention is in the drawings shown.

It shows:

Fig. 1 is a view of the plow body from the rear,

Fig. 2 plan view of the plow body of FIG. 1.

Behind the mouldboard front part ( 3 ) there are two front deflection rollers ( 5 ), each with two bearings, which rotate on a continuous, centrally curved shaft ( 4 ). The front shaft ( 4 ) is fixed at the top of the spindle ( 1 ). At the bottom, the shaft ( 4 ) is attached to the body breast ( 17 ). At the same point, a support frame ( 6 ) on the body breast ( 17 ) is horizontally movable and arranged ver adjustable on the side direction angle. At the rear end of the support frame ( 6 ) there is also a centrally arranged shaft ( 7 ) on which two deflection rollers ( 8 ) are mounted. The two shafts ( 4 , 7 ) with the deflection rollers ( 5 , 8 ) are fixed at the top by a stabilizing frame ( 9 ), so that a constant distance is guaranteed for the concentricity of a belt ( 10 a, 10 b).

The side direction angle is adjusted by a hydraulic cylinder ( 11 ). This hydraulic cylinder ( 11 ) is articulated on the support frame ( 6 ) below and on the spindle ( 1 ).

The adjustment of the angle of rotation is made possible by the fact that on the lower support frame ( 6 ) and on the stabilizing frame ( 9 ) in the region of the deflection rollers ( 5 , 8 ) there are rotatable bearing points ( 12 a, 12 b).

The angle of rotation is adjusted by a hydraulic cylinder ( 13 ) which is articulated at the top of the rear guide roller shaft ( 7 ) and at the lower support frame ( 6 ). The stabilization frame ( 9 ) and the lower support frame ( 6 ) are made telescopic, so that a perfect tension ( 14 ) of the self-rotating belt ( 10 a, 10 b) is guaranteed.

To avoid frictional resistance on the inside of the conveyor belt ( 10 a, 10 b), a continuous shaft ( 15 ) is placed between the front and rear steering roller shafts ( 4 , 7 ).

In order to prevent the soil from sticking to the belt ( 10 a, 10 b) in the case of heavy soils, an adjustable scraper ( 16 ) is provided on the rear deflection roller ( 8 ).
