Because the circle center of the axis of the bent pipe is coincident with the axis of the pin shaft, the bent pipe can be contracted and extended when rotating around the pin shaft; but the radius of the arc of the axis of the bent pipe is always unchanged, and the bent pipe is contracted together after rotating around the pin shaft. The pin shaft is cylindrical, one end of the pin shaft is provided with a head part, and the other end of the pin shaft is provided with a through hole which is inserted into the cotter pin; and springs are arranged among the rotary supporting rods, so that the bent pipe can automatically return to the original state.
When the device is used, a lifting auger of the device is fixed on a harvester, grain materials are conveyed by a spiral shaft in the lifting auger to enter a discharging box and then are discharged from a swinging bent pipe along a telescopic straight pipe to a spherical hinge end, and the spherical hinge end of the straight pipe is positioned at a grain material collecting point at the edge of a field; the grain materials are conveyed to slide down along the pipeline by gravity without power. The orientation of the harvester can be changed at any time during running, the position of a ball hinge of a straight pipe at the tail end of the device is unchanged, the whole conveying device rotates around the axis of the discharging box at the moment to adapt to the change of the orientation of the harvester, the pipe can change the inclination angle along with the position of the harvester due to the combined action of the ball hinge and the swing bent pipe at two ends, and the length of the straight pipe can change along with the position of the harvester due to the extension and contraction of the straight pipe. When the harvester travels in the field, along with the change of the position, the discharge box of the device rotates, the bent pipe swings around the pin shaft, the straight pipe stretches and retracts, the spherical hinge end rotates to change the inclination angle of the straight pipe, but the position of the straight pipe is unchanged, and the harvested grain materials can be conveyed to the spherical hinge end along the pipeline no matter where the harvester travels. Therefore, when the harvester runs in the field to harvest rice or wheat, the length and the angle of the device can be automatically adjusted no matter where the harvester runs, grain materials are conveyed to a collection point fixed on the edge of the field, and a grain bin is not required to be taken on the harvester, so that the volume and the weight of the harvester are reduced, and the harvester is lighter and more flexible. The telescopic straight pipe is made of a light-transmitting material and a heat-gathering material, and grains are dried by solar energy.
