Abstract
A device for soil preparation. The device has a direction of movement during operation. The device comprises a carrier beam for carrying disc-shaped bodies extending parallel to each other. The angle of each disc-shaped body relative to the carrier beam is adjustable and lockable by means of a first adjusting device. The first adjusting device is computer-controlled.
Claims26
A device for soil preparation, said device having a direction of movement during operation, said device comprising a carrier beam (1) for carrying disc-shaped bodies (2) extending parallel to each other, the angle of each disc-shaped body (2) relative to the carrier beam (1) being adjustable and lockable by means of a first adjusting device (9), characterized in that the first adjusting device (9) is controlled by a computer (14).
A device as claimed in any one of the preceding claims, characterized in that the computer (14) is provided with a memory (15) containing one or more data out of the group consisting of:
- map of the soil to be prepared, relief of the soil to be prepared, type of soil, cultivated crop, presence of weed, type of weed, and soil condition.
A device as claimed in any one of the preceding claims, characterized in that the device is provided with means (16) for determining the speed of movement of the device, and for supplying data regarding the speed to the computer (14).
A device as claimed in any one of the preceding claims, characterized in that the device is provided with means (17) for determining the momentary position of the device, and supplying data regarding the position to the computer (14).
A device as claimed in any one of the preceding claims, characterized in that the device comprises measuring means for measuring the momentary position of at least one of the disc-shaped elements (2).
A device as claimed in any one of the preceding claims, characterized in that each disc-shaped body (2) is mounted on the carrier beam (1) by means of a ball joint (3).
A device as claimed in any one of the preceding claims, characterized in that at least one of the adjusting devices (9, 11) also functions as a locking device.
A device as claimed in any one of the preceding claims, characterized in that the device is provided with a camera for observing the behaviour of the soil when it is thrown away by the disc-shaped elements.
A device as claimed in any one of the preceding claims, the device being moved forward by a driving vehicle, characterized in that the device is further provided with means for measuring the power respectively the torque of the driving vehicle during operation of the device, and for conveying the measurement data to the computer.
