Abstract

PURPOSE:To perform the operation of tilt rotating a frame body backward without projecting the rear end side of the frame body backward by hanging a grain bag on the frame body and providing a hook connected to the cable or chain of a winch provided in a structure such as a workshop on the front end side of a floor member. CONSTITUTION:When discharge operations are performed, the lower end of the cable or chain 40 of a winch (w) provided in a ceilling inside a structure is connected to a hook 5 provided on the front end side of the bottom member 10 of a frame body 1 supported by a base 3 on a bed (t). The floor member 10, the ceilling frame member 12 and the front frame member 13 of the frame body 1 hangingly supporting a grain bag 2 are rotated upward about connection shafts (a), (b) provided in the lower end and the upper end of a rear frame member 11 integrally connected to the base 3 by operating the winch (w). Since they are brought into such an attitude to tilt and go down toward the rear edge of the bed (t) in the state of supporting the grain bag 2, grains can be quickly discharged without protecting the frame body 1 backward.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a truck, which is usually owned by a farmer, for transporting grains harvested in a field with a combine harvester to a work place where a grain dryer is installed. In a grain carrier of a configuration in which the grain containers are freely mounted and unloaded, a grain container mounted on a truck bed is assembled into a cage, and a grain is suspended from the frame. The present invention relates to an improvement of a grain discharging device in a grain carrier configured with a grain bag.

2. Description of the Related Art As shown in FIG. 1, the grain discharging means in the grain transporting vehicle of the above-described form is constructed by suspending a grain bag 2 on a frame 1 and loading a cargo carrier t of a truck T. The grain container G to be mounted on top is provided with discharge cylinders 20 for discharging grain on both front and rear sides of the grain bag 2 respectively, and the frame 1 for suspending the grain bag 2 The floor member 10 of the inclined plate 1 in which the front and rear central portions of a portion supporting the bottom surface of the grain bag 2 is highly raised, and the front half side of the portion is inclined downward toward the front.
0a, and the rear half side of the above portion is formed into a shape that forms an inclined plate 10b that descends downwardly toward the rear, and
When the frame 1 is rotatably supported on the upper surface of the base 3 in a turntable-like manner and the grains are discharged, first, the discharge cylinder 20 on the rear surface side of the grain bag 2 is set as shown in FIG. Pull out to the rear of the loading platform t and face the receiving hopper 60 of the grain dryer 6 installed in a building such as a workplace,
From that state, the opening at the tip closed by the binding string is opened, and the grains on the latter half side in the grain bag 2 are caused to flow out by the inclined plate 10b on the latter half side. Next, the frame 1 is rotated 180 degrees with respect to the base 3 to replace the front and rear of the grain bag 2, thereby pulling out the discharge tube 20 occupying the state position facing the rear of the loading platform t to release the binding. By this, the opening on the tip side is opened, and the grains remaining on the first half side in the grain bag 2 are formed on the first half side of the floor member 10 of the frame body 10.
As shown in FIG. 3, there is a means for causing the water to flow out to the rear of the loading platform t by a.

Further, as shown in FIG. 4, the track T
The frame 1 for suspending the grain bag 2 of the grain container G placed on the loading platform t is mounted on the base 3 so as to freely rotate rearward about the connecting shaft 30, and Base 3 has
A winch w and a cable or chain 40 are wound by the winch w, and a jack 41 that operates so as to push up the front end side of the frame body 1 is installed, and the frame body 1 is tilted backward by the operation of the winch w. There is a means for causing the grains to flow out from the discharge cylinder 20.

[0004]

In the former case, the above-mentioned conventional means is used in the frame 1 during the work of discharging the grain.
There is a problem that the discharge work is troublesome because the work of turning the turntable like a turntable and replacing the front and back is required. Further, in the latter case, there is a problem that the manufacturing cost is increased by equipping the winch w, and when the frame body 1 is tilted rearward, the rear end side of the frame body 1 is rearwardly moved. The overhang causes a problem in that the tilting angle of the frame 1 is restricted in order to avoid interference with the body of the grain dryer 6 installed in the work place.

The present invention has been made in order to solve these problems occurring in the conventional means, and in order to expedite the work of discharging the grain, a frame body in which the grain bag 2 is suspended is provided. The operation of inclining and rotating the frame 1 rearward can be obtained while keeping the manufacturing cost low, and the operation of inclining and rotating the frame body 1 rearward extends the rear end side of the frame body 1 rearward. The purpose is to provide a new means to obtain without giving out.

[0006]

As a means for achieving the above-mentioned object, the present invention provides a rear end portion of a base formed in the shape of an underframe that can be unloadably mounted on the bed of a truck. A rear frame member is erected in a fixed state with respect to the base, and a rear end side of the floor member is connected to a lower end side of the rear frame member so as to rotate up and down about a connecting shaft. The rear end side of the ceiling frame member is connected to the upper end side of the member so as to rotate up and down about the connecting shaft, and the upper end side of the front frame member is connected to the front end side of the ceiling frame member by the connecting shaft. The front frame member is rotatably connected, and the lower end side of the front frame member is rotatably connected to the front end side of the floor member by a connecting shaft so that the frame member is assembled on the base, and the frame member is mounted on the frame member. Suspend the grain bag, and on the front end side of the floor member, a winch cable installed in a building such as a workplace or Cheng and interlocking means hook is intended to raise the grain of the discharge device in grain transportation vehicles and comprising So設.

[0007]

The grain discharging device in the grain carrier according to the present invention having the above-described structure is provided with the grain carrier A in the workplace where the grain dryer 6 is installed or in the building of the grain processing facility. The rear surface side of the grain bag 2 in which the rear end side of the loading platform t of the truck T that constitutes the transport vehicle A is opposed to the receiving hopper 60 of the grain drying machine 6 and is suspended on the frame 1 on the loading platform t. The winch w is installed in the building by pulling out the discharge cylinder 20 and exposing the tip opening 21 of the discharge cylinder 20 into the receiving hopper 60, and in that state, the hook 5 that is installed at the front end of the frame 1 is installed in the building. Frame or suspension of the grain bag 2 by connecting the lower end of the cable or chain 40 and operating the winch w to wind up the cable or chain 40.
Is tilted backward around the connecting shaft 30 connected to the base 3 on the loading platform t, and the grains in the grain bag 2 are quickly discharged into the receiving hopper 60 of the grain dryer 6. Like At this time, the frame body 1 for suspending and supporting the grain bag 2
The rear frame member 11 is integrally connected to the base 3, and the floor member 10, the ceiling frame member 12, and the front frame member 13 are vertically rotated in parallel with the rear frame member 11, Grain bag 2
Since the floor member 10 is tilted rearward while bearing the bearing, the frame body 1 is held in a state in which there is no rearward extension of the frame body 1.
