"Agricultural equipment provided with means for dewatering crops"

The invention relates to an agricultural implement provided with at least one means for dewatering crops comprehensive heater, a heater supporting. a mobile frame and with funds for conveying the crop.

In the known agricultural implement, there is a heating chamber present, v / o the conveying means or at least part of the same run through. With this agricultural Therefore, apart from the walls # n of the heating

the

Chamber also exposed these funds to heating.

This agricultural device is according to the invention improved by the fact that the heating beam of the heater is mainly outside of the agricultural equipment is located and that the conveyor means the crop picked up from the field in the outside of the agricultural implement throw the heating beam.

In this agricultural device, the heating beam from the heater mainly heats the crops, while the the agricultural equipment itself is not or hardly at all affected by the heat of the heating beam.

The conveying means preferably throw the plants picked up from the field into the heating jet close to the ground.

The drawn in Figures 1 and 2 according to the invention agricultural device is a receiving device 67 with a frame 1, which by means of suspension rods 3 on a not drawn tractor is coupled. A crankshaft 4 is fixedly attached to the frame 1. To the crankshaft 4 is a Pick-up rotor 5 rotatably mounted, which is driven in a manner not explained in detail by the branch axis of the tractor. Around the crank 6 of the stationary crankshaft 4 are rotatably mounted receiving pins with a variable. Length outside of the take-up rotor 5 protrude so that they can take up and release the plant without it around the take-up rotor 5 to wrap. "

According to the invention, the frame 1 carries a means of fastening 11 attached to the frame 1 burner 9> whose flame 10 is directed downwards.

The funds formed by the pickup rotor 5 throw the picked up crop 12 outside of the agricultural area Device behind the same in the flame 10. The flame 10 hits this plant 12 close to the ground.

Preferably a plurality of burners 14 are arranged side by side, so that a extending over the working width of the agricultural machine λ-Community flame front is formed. 13

The flame front 13 of burners 14 (see FIG. 2) is preferably directed obliquely backwards from above, so that the flame front 13 also streaks over the plant 15 already lying on the ground.

In Figures 1 and 2 burners 9 respectively. H via air lines 16 connected to a fan 17. Furthermore, the burners are connected to a fuel container 18 via a pump 19 connected.

The illustrated in Figures 3 and 4, moving according to the arrow mower 24 comprises a frame 36 which is about horizontal Spigot 44 of a container 52 can be hinged, which container 52 can be attached to a farm tractor can and on which container 52 an axle 53, which can be coupled to the branch axle of the agricultural tractor, is stored. The axle 53 drives an axle 50 via a cable drive 47 and a bevel gear 48.

Two mower discs 31, each of which have knives 32 and around vertical Axles 33 are rotatable, are driven by the axis 50 via bevel drives 34 and 35 and an intermediate axis 37.

Furthermore, the mower 24 comprises a conveyor-forming device 45 for picking up and releasing plants, which device 45 consists of a shaft 50 driven by a cable drive 38 and rotatable about horizontal pin 39 mounted Botor 40 and a hood 41 consists. The eotor 40 comprises two or more conveying members 42. Between the fiotor 40 and the hood 41 there is a flow channel for the plant on the top.

The botor 40 throws the crop behind the machine into the flame front 54 of several juxtaposed Burners 55, which are fastened with the aid of an adjustable fastening rod 56, which engages on one ear 70 of the mower 24 are attached to the frame 36 so that the angle 57, which includes the flame front 54 with the vertical, is adjustable. The houses of the burner 55 are immediately on with air guide plates 23 provided fan housing 58 connected. The fan rotor 20, like the fuel pump 21, is over a transmission 22 driven from the branch axle of the tractor. Swath boards 59 regulate the swath width and at the same time prevent the flame front from pushing the vegetation away to the side.

The houses of the burners 55, the fan housing 58, the fuel pump 21, the gearbox 22, the mounting rod and two attachment ears engaging ears 71 of mower 24 68 together form a heating unit 69 which, as FIG. 5 shows, is suspended from a receiving device 67 which is provided with fastening means formed by ears 72 and 73 for this purpose. If very wet If grass has to be mowed, the grass can be mowed and heated by means of a mowing machine 24 with a heating unit 69 will. The heating unit 69 can then be removed from the mower 24 and suspended from a receiving device 67 so that after some time these plants lying on field I are picked up by means of the pick-up device 67 and thrown again into the flame front 54 of the burners 55 v / can earth.

The heating unit 69 is preferably fastened by means of pins 91 which can be easily pulled out.

The agricultural implement of Figure 6 comprises a mower 24 described in Figures 3 and 4, wherein the Burner 60 - instead of top to bottom - from the side to the central longitudinal surface 61 are directed opposite to each other. The eotor of the mower throws the crop that has been cut and picked up wax 62 on the point where the flames 63 of the burners 60 are are located. This plant 62 ends up in a swirling flame hearth and is heated evenly. The required fuel consumption is small in this agricultural implement.

FIG. 7 shows a mower with both two burners 60 directed from the side and obliquely downward from above directional burners 64.

Figure 8 shows a detail of a further developed mower according to FIG. 6, with the burner under the flames 63

109818 / U76

a screen 65 is provided, which prevents the upper ends of the stubble 66 from being overheated. So the period of growth of these stoppers 66 is reduced. This screen can be made of heat-resistant material, e.g. asbestos be made.

The heater can be formed by a steam spray nozzle instead of a burner with a flame.

_. Thus, Figure 9 shows a mower 24 with a steam ™ device 74 is provided, comprising a boiler 75 with a flame tube 76 arranged in a burner chamber 77, one connected to the boiler 75 via a water pump 78 Water tank 79, a burner SO, an air blower 81, a fuel pump 82, a fuel tank 83 and at least a nozzle connected to the boiler 75 via a valve 87 for emitting a steam jet 85 which is directed towards the flow of vegetation 86 is.

Tests have shown that the plant can be heated well with steam. The scope of the steam device with the many required water is disadvantageous.

Therefore, a heater in the form of a burner is preferred.

In Figure 10, a burner unit 87 is shown, which the Heating unit, 69 corresponds in the sense that a spray nozzle 88 is arranged in the outlet of the fan housing 58, which Via a high pressure pad 89 on a water container 90 • is connected and which clouds the water in this outlet.

Possibly a not drawn water spray nozzle "for steam formation in the burner chamber of the burner 55 or itself Spray outside the Brennir 55 in the flame front.
