Description: TECHNICAL FIELD [0001] The present invention relates to a grain carrier configured by mounting a grain hopper on a bed of a truck, the grain hopper of which is an internal cavity. An auger for grain discharge is horizontally supported at the bottom of the machine along the front-rear direction, and is configured to face the discharge port opened at the bottom of the machine wall on the terminal side in the transport direction. Grain in a grain carrier configured by connecting a grain conveyor that stores a carrier in which a steel wire is wound into a coreless coil in a flexible transport cylinder to the discharge port of the car grain hopper The present invention relates to the improvement of the discharge device.

[Prior Art] The above-described grain discharging device in a grain transport vehicle is usually a grain transport vehicle in which a grain hopper 1 is mounted on a loading platform t of a truck T, as shown in Fig. 1. When constructing A, the grain hopper 1 mounted on the loading platform t of the truck T
The discharge port 11 provided at the lower part of the machine wall 10 thereof is provided with the connecting tube portion 12 having the attachment flange portion 120.

Then, a grain conveyor a, which rotatably stores therein a carrier 3 in which a steel wire or the like is wound in a coreless coil shape in a flexible transport cylinder 2, is provided at the end of the transport cylinder 2. Is closed to the mounting flange 120 of the connecting cylinder 12, and the end of the spiral carrier 3 wound in a coreless manner on the starting end side is provided horizontally at the bottom of the grain hopper 1. Connected and connected to the outer end of the rotary shaft 40 of the auger 4 for discharging particles, the spiral conveyor 3 is rotated by the drive of the auger 4, and the auger 4 discharges the discharge port.
The grain delivered to 11 is received in the transporting cylinder 2 of the grain transporter a connected thereto, and is transported by the coreless coil-shaped spiral transporting body 3 which is connected to the rotating shaft 40 of the auger 4 and rotates. It is configured to be conveyed toward a discharge port opened on the other end side of the cylinder 2.

This is because the grain transport vehicle A of the above-described form transports the raw grain harvested after harvesting a combine or the like in the field to the work house where the grain dryer is installed, or the grain drying facility.
