[Industrial applications]

 The present invention provides a grain hopper on the bed of a truck for transporting grains harvested in the field by a harvester such as a combine harvester to a storage house or a grain drying facility in which a grain dryer is installed. The present invention relates to an improvement in a grain carrier that is constructed by mounting.

[0002]

[Prior art]

 As shown in FIG. 1, the grain transport vehicle A of the above-described form is usually equipped with a box-shaped grain hopper a on the upper surface of the loading platform 10 of a truck 1 owned by an ordinary farmer. The grain hopper a is mounted with a screw conveyor 3 for discharging the grain in the bottom of the inner cavity of the fuselage 2 in which the grain feeding direction is forward and backward, and the grain feeding spiral 30 The end side in the conveying direction of the is exposed to the inside of the discharge tube 20 installed in the lower portion of the rear side of the machine body 2 of the grain hopper a, and inside the machine body 2, as shown in FIG. Grain board 2 1.22 which is inclined downward toward the upper edges of the left and right side walls of the grain feeding trough 31 of the screw conveyor 3 is installed, and the grain feeding board 21 A shutter plate 4 that opens and closes the opening on the upper side of the gutter 31 is slidably mounted, and is attached to the lower side of the discharge cylinder 20. A discharge port 23 is opened, and a suspending member 5 that freely swivels around the axis of the discharge port 23 is installed around the discharge port 23. As shown by the chain line in FIG. 1, the grain conveyor 6 can be removably connected, and the grain transfer device 60 can be mounted in the grain transfer cylinder 60 of the grain transfer conveyor 6 which is removably connected. A motor M1 for driving the spiral 61 is assembled to the suspension fitting 5 in advance.

[0003] Thus, when the grain is conveyed, the shutter plate 4 closes the opening on the upper surface side of the grain feeding gutter 31 of the screw conveyor 3 provided in the machine body 2 of the grain hopper a. In this state, the grain is received in the grain hopper a, and the truck 1 is operated in that state to transport the grain to a desired place. Thus, when the grain is transported to a predetermined place, the operation of the truck 1 is stopped, the shutter plate 4 inside the grain hopper a is opened, and the body 2 of the grain hopper a on the bed 10 of the truck 1 is opened. Connect the power cord to the motor M2 attached to the power outlet of the commercial power source installed in the workplace where the truck 1 is installed, and operate the screw conveyor 3 for discharge to operate the grain hopper a. The grain inside the machine is discharged to the outside of the machine from the discharge port 23 on the lower surface of the discharge cylinder 20.

At this time, in the case where the lower portion of the discharge port 23 is a pit for receiving the grain provided on the floor surface of the work space of the grain drying facility, the grain discharged from the discharge port 23 is directly pitted. However, there is no such pit and there is no grain hopper for relay, and the grain is fed to the hopper of the grain dryer installed at the workplace. When attempting to do so, the base end of the grain transfer cylinder 60 of the grain transfer conveyor 6 for grain transfer is inserted into the hanging metal fitting 5 provided around the discharge port 23, and the grain transfer spiral of the same is inserted. The base end portion of 61 is conducted to the output shaft of the driving motor M1 supported by the suspension fitting 5, and the motor M1 is connected to the socket of the commercial power source in the workplace like the above-mentioned motor M2. It is operated by connecting the power cord to the The grain discharged from the discharge port 23 is sent to the grain dryer using the a.

[0005]

[Problems to be solved by the device]

 In the above-mentioned grain carrier A, the shutter plate 4 is closed to disconnect the communication between the screw conveyor 3 provided at the bottom of the machine body 2 of the grain hopper a and the inner cavity of the grain hopper a. Since the grain is received and transported in the grain hopper a, the discharge port 23 on the lower surface of the discharge cylinder 20 projecting to the rear surface side of the machine body 2 of the grain hopper a causes a problem even in the opened state. However, when the transportation work is repeated, when the shutter plate 4 is tightened, the grains remaining at the bottom of the grain feeding gutter 31 of the screw conveyor 3 cannot be completely discharged during the previous transportation work. Since the grains remain in the state as they are, the residual grains flow out from the discharge port 23 on the lower surface of the discharge cylinder 20 due to the vibration when the truck 1 is operated for carrying work. There's a problem.

Therefore, if a shutter plate that is opened and closed by manual operation is provided at the discharge port 23 on the lower surface of the discharge cylinder 20, the shutter plate is forgotten to open and the screen conveyor 3 is operated. When the discharging work is performed, a problem occurs that the screw conveyor 3 fails.

In addition, the shutter plate thus provided at the discharge port 23 is attached to the hanging metal fitting 5 installed around the discharge port 23 at the base end of the grain transfer cylinder 60 of the grain transfer conveyor 6 for grain transfer. If you open it automatically by inserting the side, when you directly discharge from the discharge port 23 to the pit of the grain drying facility, if there is no key grain conveyor 6, the discharge port 23 will be opened. There is a problem that inconvenience occurs.

[0008]

【Purpose】

 The present invention has been made in order to solve these problems, and when the grain carrier A is driven by the operation of the truck 1 to transport the grains, the discharge port 23 is closed. In addition, the grains remaining inside the grain feeding trough 31 of the screw conveyor 3 in the body 2 of the grain hopper a are discharged by the vibration of the machine during traveling and the discharge port 23 provided on the lower surface of the discharge cylinder 20. It is possible to prevent the discharge from flowing out to the outside without fail, and even if the screw conveyor 3 is operated by forgetting the operation to open the discharge port 23, the grain from the discharge port 23 It is an object of the present invention to provide a new means for ensuring that the discharge operation of grains is performed without any hindrance.

[0009]

[Means for Solving the Problems]
