Description

114849 CULTIVATION SERVICE TECHNICAL FIELD

The invention relates to the maintenance of cultures. In particular, the invention relates to a cultivation maintenance ramp 5 and a method for moving it.

Technology background

For the maintenance of the crops, especially for irrigation, ramps are used which comprise wheeled end carriages and bridge structures therebetween with, for example, 10 nozzles for water distribution. The ramp can be up to 80 meters wide and the service area can be, for example, 100 - 300 m. The device can run, for example, on smooth rails and rubber wheels. Also known as the rack rack and rack gears are known.

The water can be supplied by suctioning water from a water channel adjacent to the device with a pump in the device, and pumping the water through pipes to irrigation and fertilization nozzles. Another possibility is to bring water and propulsion through a hose and cable, especially for a smaller appliance such as a greenhouse. The prior art device is disclosed, for example, in Japanese Patent 2000166404.

t. 20 Ensuring smooth travel has often been a problem. The simultaneous movement of the traction wheels, · 'to, and the end wheels is ensured in prior art devices »·,. produced problems. Electronic controls and controls increase the price of the whole.

,>. In windy conditions, there is a risk of uncontrolled transfer of the device, and at worst the wind. ' : can throw the unit completely out of the area, causing severe damage to the unit and plants.

Description of the Invention

In order to solve the problems described above, an improved crop maintenance apparatus and a method for moving it have been invented. According to the invention, loop chains are arranged parallel to the edge of the area to be cultivated, i.e. in the direction of travel of the device. These are introduced by suitable means through the rotating or reciprocating drive members on the movable part of the device so that precise movement and positioning of the device is possible.

The traction can be done by electric motor, internal combustion engine, hydro or oil hydraulics or other suitable power source.

10 The main purpose of the device is usually irrigation. In addition, it is possible, for example, to apply fertilizers and spray pesticides. Precise positioning also enables efficient utilization of various attachments. These include conveyors, manipulators, and lamps, fans, or syringes for the transportation and handling of breeding cells or other material.

The device according to the invention is precisely positioned because the chain drive makes it easy to synchronize the movement of both ends. Positioning accuracy is necessary not only for irrigation but also to ensure the function of any attachments that may be installed in the device.

Preferably, the chain utilizes a cross-link link chain, which is inexpensive and reliable, but still provides sufficient opportunities to provide an accurate traction mechanism, as it can be coupled to a correspondingly shaped drive wheel, as known to one skilled in the art.

In addition, the drive unit effectively anchors the device so that it cannot be moved by the wind. In the direction of travel, a rail may be provided to guide the device and to support the wheels. The structure of the figures, comprising two end carriages, is not essential to the invention, but the structure may comprise a plurality of end carriages and trusses between them, depending on the size of the device and its intended use.
