Description

Description: TECHNICAL FIELD [0001] The present invention relates to a grain carrier configured by mounting a grain hopper on a bed of a truck. An auger for discharging grains is mounted at the bottom of the inner cavity along the front-rear direction, and the end of the auger is exposed to the discharge port opened at the bottom of the machine wall on the rear side of the grain hopper. In the grain carrier that is the one of the above, the grain discharged from the grain hopper discharge port can be flexibly moved to the grain hopper discharge port so that it can be transported to a desired place. The present invention relates to an improvement of a grain discharging device in a grain transport vehicle configured by connecting and connecting a flexible grain conveyor in which a coreless coil-shaped transport body is housed in a transport cylinder.

[Prior Art] The above-described grain discharging device in the grain transporting vehicle is generally a grain transporting system in which a grain hopper 1 is mounted on a loading platform t of a truck T as shown in Fig. 1. In car A, a discharge port installed in the lower part of the machine wall 10 of its grain hopper 1.
On the outer surface side of 11, there is provided a connecting cylinder portion 12 having a mounting collar portion 120, and a steel wire or the like is wound in a coreless coil shape in the flexible conveying cylinder 2 An end portion of a transporting container 2 of a grain conveyor a, which rotatably stores a body 3, is closed at the end of the mounting flange 120, and an end portion of a spiral transporting body 3 wound in a coreless coil shape. Is connected and connected to the outer end of the rotary shaft 40 of the auger 4 for discharging the grain that is laterally provided in the bottom of the grain hopper 1, and the spiral conveyor 3 is rotated by the drive of the auger 4. The grain delivered to the discharge port 11 by the auger 4 is received in the transport cylinder 2 of the grain conveyor a,
It is configured to be conveyed toward a discharge port opened on the other end side of the conveying cylinder 2 by a rotating conveyer 3 having a core-like coil shape.

This is because the grain transport vehicle A of the above-described mode transports raw grain harvested by a harvester such as a combine in the field to a work house where a grain dryer is installed or a grain drying facility. It was developed to do so, and when the grain is transported to the work house or the grain drying facility and discharged, the position at which the grain carrier A is stopped is set to the grain dryer. It is difficult to align with the entrance of the grain hopper, and usually the grain carrier A is parked at an appropriate place, and the discharge port 11 of the grain hopper 1
The grain conveyor a connected to the above is adapted to perform the alignment. In order to perform this alignment simply and easily, the grain conveyor a connected to the discharge port 11 of the grain hopper 1 is connected to the transport cylinder 2 This is because it is in the form of a so-called spring contact that can flex freely.

[Problems to be Solved by the Invention] As described above, the starting end of the transfer cylinder 2 of the grain conveyor a, which is flexible, is formed at the outer end of the connecting cylinder 12 provided at the discharge port 11 of the grain hopper 1. The side is connected and connected, and the starting end side of the coreless coil-shaped carrier 3 in the carrying cylinder 2 is connected to the terminal end of the grain discharging auger 4 located in the connecting cylinder 2. The grain discharging device in the constituted grain carrier A smoothly transfers the grain at the connection portion between the end of the spiral blade 41 of the auger 4 and the start of the coreless coil-shaped carrier 3. There is a problem that the grain tends to be clogged at this connection site due to the lack of the grain.

In addition, the grain discharging device in the grain transporter puts the grain transported by the grain transporter from the field to the work house or the grain drying facility into the inlet of the grain dryer installed there. In doing so, it is configured by connecting the grain conveyor a to the discharge port 11 of the grain hopper 1 of the grain carrier, and when the discharge / feeding of the grains is completed, Since the connected grain conveyor a is removed and the grain carrier A is returned to the field, it is hoped that the removal of the grain conveyor a can be done quickly and simply, but the auger of the grain hopper 1 4 is connected to the shaft end of the rotary shaft 40 of the grain conveyor a, and the starting end side of the coreless coil-shaped carrier 3 is also troublesome to remove. .

The present invention has been made in order to solve the above-mentioned problems that occur in the grain discharging device in the conventional grain transport vehicle, and includes the end portion of the auger 4 of the grain hopper 1 and the grain conveyor a. The starting end of the coreless coil-shaped carrier 3 can be connected so as not to cause clogging at those connection sites, and the connection and disconnection can be performed quickly and easily. The purpose is to provide new means.

Since the connecting blades are connected and communicated with each other, the grain feeding operation by the spiral blade 41 of the auger 4 is obstructed by the resistance of the bearing support member, and the grain of the coreless coiled carrier 3 to be connected is connected. It has been found that the contact area with the spiral blade 41 of the auger 4 is smaller than that of the spiral blade 41 of the auger 4 because the grain transfer ability of the carrier 3 is lower than that of the spiral blade 41 of the auger 4.

In addition, the problem of the attachment and detachment of the connection portion is that the connection shaft portion provided on the starting end side of the coreless coil-shaped carrier 3 of the grain conveyor a has been previously attached to the auger 4 of the grain hopper 1. Since the shaft end of the rotating shaft 40 is connected by fitting and tightening with a set bolt, or by spline shaft fitting and connection, work for centering and screwing the set bolt Is caused by the need for
On the side of the grain hopper 1, a clutch engaging tooth 50 is provided at the tip of the rotary shaft 40 of the auger 4 to which the large-diameter spiral blade 41 'described above is attached.

Is provided, and the start end side of the coreless coil-shaped carrier 3 is connected and connected to the end of it, thereby performing a troublesome work such as centering of the connection shaft 401 and the rotation shaft 40 of the auger 4. Without needing
Moreover, the rotary shaft 40 of the auger 4 and the coreless coil can be operated by simply closing the starting end portion 2a of the transport cylinder 2 to the connecting cylinder portion 12 of the grain hopper 1 without hindering the transfer of the grain.
