Abstract

Disclosed is an improved articulated combine of a forward grainhead carried by a forward bogey devoid of grain storage and operated by an operator and a rear grain storage bogey capable of crabbing. Proximity sensors are affixed to the side of the grainhead and on the side of the rear end of the rear bogey. Cameras are affixed to the front of the forward bogey looking to the side of the forward bogey, to the front of the rear bogey looking rearwardly into the rear bogey grain storage, to the rear of the rear bogey, and on the grain arm discharge end. Readout from the sensors are fed to memory for each type of grain off-loading vehicle for later use by the operator in placing the combine in the optimum unloading position. Video also is fed to a display confronting the combine operator.

Claims

1. An improved articulated combine of a forward grainhead carried by a forward bogey devoid of grain storage, having an unload side and operated by an operator, and a rear grain storage bogey having an unload side and capable of crabbing, the improvement comprising:

(a) proximity sensors affixed to the sides of the grainhead and on the unload side of the rear bogey;

(b) memory for storing distance values from the proximity sensors for each type of grain off-load vehicle for later use;

(c) cameras affixed to the front of the forward bogey looking to the unload side of the forward bogey, to the front of the rear grain storage bogey looking rearwardly into the rear grain storage bogey, and to the rear of the rear grain storage bogey;

(d) readout from said sensors being fed to a first video screen facing the combine operator; and

(e) video from said cameras being fed to a second video screen facing the combine operator;

the combine being steerable adjacent to a grain off-loading vehicle for the combine to unload grain stored in the rear grain bogey into the grain off-loading vehicle.

2. The improved articulated combine of claim 1, wherein a grain unloading arm is located at the rear of the rear grain bogey for unloading grain, said grain unloading arm having a distal grain discharge end.

3. The improved articulated combine of claim 2, wherein a camera is disposed at the grain unloading arm distal grain discharge end.

4. The improved articulated combine of claim 1, wherein the proximity sensors also are connected to a processor for recalling stored distance values from memory for different types of grain off-loading vehicles.

5. The improved articulated combine of claim 4, wherein the combine can be automatically crabbed into position for grain unloading.

6. An improved articulated combine of a forward grainhead carried by a forward bogey devoid of grain storage and operated by an operator and a rear grain storage bogey capable of crabbing, the improvement comprising:

(a) proximity sensors affixed to the unload side of the grainhead and the rear bogey;

(b) memory for storing distance values from the proximity sensors for each type of grain off-load vehicle for use later use; and

(c) readout from said sensors being fed to a video screen facing the combine operator; and

the combine being steerable adjacent to a grain off-loading vehicle for the combine to unload grain stored in the rear grain bogey into the grain off-loading vehicle.

7. The improved articulated combine of claim 6, wherein the proximity sensors also are connected to a processor for recalling stored distance values in memory for different types of grain off-loading vehicles.
