My files: g 30-y Emilio Günther, Pdrto Alegre RGS. / BRAZIL Rice harvest masohine

The invention relates to a mobile iron harvester self-propelled or as an additional device for a locomotive, z «B. a tractor.

Although rice is one of the main staples, it is today still harvested by hand in the traditional way and then threshed. They are well known combine harvesters, however unsuitable for the rice harvest »because the rice fields are not passable with them because of their heavy weight. Also prevented lack of maneuverability their use in the rice fields divided into relatively small parcels,

The invention is based on the object, through a harvesting machine adapted to the particular conditions in rice cultivation, the Mechanize rice harvest.

According to the invention, this object is achieved by one attached to the front of the motor vehicle, the panicles of rice plants reaching under and pointing with its teeth in the direction of travel Comb as well as a collecting container arranged in the area of the comb back for the rice grains combed from the straw solved «It is advantageous to have a spiral brush attached to the comb to wrap around your The axis running parallel to the ridge rotates and its spatial axis Arrangement is chosen so that their bristles brush the top of the comb from the teeth to the back. The collecting container is preferably trough-shaped and has a screw conveyor in its cavity, with the help of which the rice grains, which have been stripped from the stalks by the comb and thrown into the collecting container by the spiral brush, in be promoted to a collecting container. To the collection container this is followed by a further conveying device which ends in a silo or a bagging funnel «.

At the tooth tips of the comb, points pointing in the direction of travel are curved attached to the ground inclined erector, which eiepiel example can consist of a resilient wire, and which serve to grasp the panicles of bent or crooked stalks and insert them into the comb »Another improvement the panicle introduction into the ridge results when, according to a further embodiment of the invention, in the direction of travel above In front of the tooth tips of the comb, insert the rice panicles into the comb

Introductory feeder is arranged * which, for example, from a number of arranged transversely to the direction of travel connected by endless chains and driven rake-like elements consists"

The parts that are used directly for the harvesting process, such as the Comb with the spiral brush, the AuffangbehSltex ^ with the screw conveyor and the feeder preferably form a structural unit that is height-adjustable and connected to a suitable locomotive is. A hydraulic adjustment direction can be used to adjust the height. The spiral brush, the screw conveyor and the feeder are advantageously driven by a power take-off shaft of the locomotive. To drive on the rice fields too enable the traction vehicle to be appropriately equipped with rubber tracks "

The erfindungsgeraaße harvesting machine can be connected to relatively light and agile locomotives * If necessary it as an accessory for existing locomotives, ZeB. Tractors are suitable. * This latter form of training involves in particular for smaller farms, "where the tractor used as a multipurpose vehicle wi ^ xl, another way of Fahrzeugnutaung" The simple and low vulnerability structure of erfindungsgomSßcn Rfiserntenaschine also permits its operation by technically whoever _t \ r »trained staff,

With reference to the schematic drawing, the following is an exemplary embodiment of a travel harvester designed according to the invention and how it works is explained in more detail; show it:

Fig. 1 is a side view of the rice harvester; Fig. 2 is a top plan view of the rice harvester; Fig. 3 is a side view of the comb;

Fig · H a top view of a section of the comb ₀

On the front of a motor vehicle running on rubber tracks 1, the rice harvester forming a structural unit is attached, the basic elements of which consist of one with its tooth tips in the direction of travel comb 2 and a rotating spiral brush 3 exist, the bristles of which the top of the comb 2 of Brush the tips of the teeth towards the back of the comb. In the back area a trough-shaped collecting container is arranged on Carnies 2, which receives a screw conveyor 5 in a cavity. To the Tips of the teeth of the comb 2 are fastened erector 6 which is bent against the ground and which are used to erect rice stalks that are not upright. Above in front of the tooth tips of the Comb 2, a feeder 7 is provided, which consists of rake-shaped Elements 19, which, for example, coupled by endless chains, introduce the rice panicles into the teeth of the comb 2. The spiral brush 3, the screw conveyor 5 and the feeder 7 are driven by a

BAD ORSGtNAL PTO shaft 8 of the motor vehicle 1 but chains 3 driven »

The harvesting machine is fastened to the traction vehicle 1 in a height-adjustable manner by means of a handlebar 9. The height is adjusted by a hydraulic device 10. It closes on the screw conveyor S Another conveying device 12, which conveys the harvested rice to a bagging hopper 13, adjoins. A collection silo can also be used in place of the bagging funnel.

The comb 2 is, as FIGS. 3 and * show, composed of individual elements 14, which are secured in the back area by claws are supported in a bed 17. The elements If are T-shaped in the tooth area and open into tips IS.

During the harvest, the rice panicles are introduced into the comb 2 with the assistance of the erector 6 and the feeder 7 and the Grains of rice stripped. The spiral brush 3 hurls the grains of rice loosened from the stalk into the collecting container t, which is covered with an impact screen 18 in the direction of the centrifugation. The screw conveyor 5 moves the rice to the conveyor 12 through which it reaches the bagging funnel 13.
