DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention concerns an agricultural baler of the type having a crop pick-up device at its front end.
BACKGROUND AND INFORMATION DISCLOSURE STATEMENT
Agricultural balers are known which have at least a pick-up conveyor as well as a processing device, wherein the quantity of harvested crop picked up by the pick-up device is fed by a conveyor device to the processing device, and then to a delivery device. Such agricultural machines do not have an independent power drive so that it is necessary to attach them to a pulling vehicle, for example a tractor. The various components of the agricultural baler are driven by a power take-off from the tractor, thereby complicating the operation thereof. Because the power is transmitted from the power take-off of the tractor to the baler, power and energy losses occur. In addition, the operation of the tractor drawn baler is complicated both during the operation in the field and on the road due to its length. The utilization of such a unit on inclines is likewise limited.
U.S. Pat. No. 2,834,177, describes an agricultural machine having a conveyor device mounted beside the machine, such that the feed is transversal rather than longitudinal. Thus, the harvested crop is picked up beside the machine, fed transverse to the direction of travel into the processing device, in which case the inlet of the processing device is on the side of the machine. The resulting width of the machine complicates the maneuverability thereof and there is a danger that the harvested crop lying on the field may be run over by the wheels of the machine. The machine of U.S. Pat. No. 3,006,207 is similar to that shown in U.S. Pat. No. 2,834,177.
French patent document 2 224 288 describes an agricultural machine which has a pick-up, conveyor and a processing device, whereby a quantity of harvested crop is picked up on the pick-up device and is fed by the conveyor device to the processing device. The harvested crop is then passed through a delivery device. The vehicle is self-propelled, having its own power drive, and the processing device is a baler for forming large bales from a quantity of harvested crop. The baler has at least one bale chamber as well as baling and conveying elements. The machine, designed as a vehicle, has at least one front wheel assembly and one rear wheel assembly, with one wheel assembly driven and the same or the other wheel assembly steerable. In the French patent document 2 224 288, the conveyor device is in front of the front wheel assembly and arranged almost vertically in order to feed the harvested crop to the processing device in an upper area of the machine. With such a conveyor device, a height component has to be factored in since the opening for the processing device is at the upper end of the vehicle.
OBJECTS AND SUMMARY OF THE INVENTION
The object of the present invention is to provide an agricultural machine that operates economically, in particular on large scale farms. It is a further object to provide a machine that can be handled effectively during operation and avoids the herein before mentioned disadvantages of prior art balers and wherein the over-all productivity is increased and the cost of baler production is reduced.
In the present invention the pick-up device, the conveyor and the processing devices are integrated into a self-propelled and steerable vehicle which is easily controlled by the operator and produces large bales in a cost effective manner. Due to the resulting dimensions of the vehicle, it is particularly suitable for use on large scale farms.
According to the invention the processing device is designed to form large bales from a quantity of harvested crop. These large bales have essentially a circular cross section (round bales) or an essentially rectangular (square bales) cross section. The processing device of the vehicle is designed such that the large bales maintain their shape by means of rope, wire, netting, plastic film or alternatively by the baling operation alone.
