2. Description of the Related Art A grain carrier A of the above-mentioned form is usually mounted on a loading platform t of a small truck T, as shown in FIG.
It is configured by loading the separately formed grain hopper H and retaining it on the vehicle body of the truck T by appropriate retaining means. When the grain harvesting season is over, the grain hopper H unloads the cargo from the loading platform t of the truck T and stores it in a barn or the like until the next harvesting season. I am trying to use it as a form.

However, in order to configure the grain carrier A, when the work of loading the grain hopper H on the loading platform t of the truck T and the harvest season are completed, the truck T is finished.
In the work of unloading the grain hopper H from the loading platform t, since the weight of the grain hopper H is usually about 150 kg to 200 kg, the casters c are mounted on the left and right side surfaces of the grain hopper H. It is assembled by detaching it and using it.

The caster c used in this manner has a free wheel 10, a vertically long support leg 11 which is adjustable at its lower end to allow expansion and contraction, and the support leg 11 to serve as a machine frame 2 of the grain hopper H. The bracket 12 is provided so as to project laterally from the upper end side of the supporting leg 11 so as to be detachably attached to the outer surface of the supporting leg 11.

This caster c has a supporting leg 11 for supporting the free wheel 10 at its lower end when it is assembled to the grain hopper H.
However, in rear view, the bracket 12 for locating the truck T off the load carrier t to the side thereof.
Is arranged so as to be slidably contacted with the upper surface of the loading platform t, the tilting plates 30 on the side edges of the loading platform t that are pivotally supported on the left and right side edges of the loading platform t are rotatably and rotatably supported. It is necessary to release the bracket and rotate it in a posture of hanging it down. Since this work is troublesome, the bracket 12
Are arranged so that, when the free wheel 10 at the lower end of the support leg 11 is in the grounded state, the lower edge of the bracket 12 is located above the upper edge of the swing plate 30 in the upright state.
Installed on the column 20 of the machine frame 2 of the grain hopper H.
・ It is attached to the side of 20.

[0006]

According to the above-mentioned conventional means, the bracket 12 of the caster c is mounted on the side surface of the machine frame 2 of the grain hopper H at the upper and lower intermediate sides of the support columns 20. In order to load or unload the grain hopper H with respect to t, the support leg 11 of the assembled caster c serves as a connecting point with the bracket 12 and is a locking fulcrum a.
When the weight of the grain hopper H is supported by the casters c by being rotated so as to be in a posture perpendicular to the center, the weight of the column 20 is supported by the columns 20 ...
A lateral bending load is applied to the upper and lower intermediate parts of the column, and the column 20 is deformed.

[0007]

The present invention has been made in order to solve the above-mentioned problems occurring in the conventional means, and it is a track T
And a grain hopper H that can be freely loaded and unloaded on the platform t
In the grain carrier configured with, the caster c used for rationalizing the work of loading and unloading the grain hopper H onto the loading platform t, while keeping the tilting plate 30 on the side edge of the loading platform t upright, While being removably assembled to the outer surface of the machine frame 2 of the grain hopper H, the machine frame 2 can be firmly assembled to the machine frame 2 without causing deformation of the support column 20 of the machine frame 2 and the machine frame 2 itself. The purpose is to provide a new means to

[0008]

In the present invention, as means for achieving the above-mentioned object, a separately assembled grain hopper is removably mounted on the bed of a truck. In the grain carrier, the connecting rod provided on the inner end side of the bracket of the caster is bridged between the upper surface of the bottom girder and the lower surface of the intermediate girder at the side of the machine frame of the grain hopper in the vicinity of the column. The engaging pins provided at both upper and lower end portions thereof are engaged with the engaging holes provided at the upper surface of the bottom girder and the lower surface of the intermediate girder, and the bracket is assembled to the machine frame. On the outer end side of the bracket, a support leg of a caster for pivotally supporting a free wheel on the lower end is assembled by fitting a locking fulcrum provided on the bracket and an engaging part provided on the upper end side of the support leg and tightening with a lock lever. Grains in a grain carrier characterized by being attached It is intended to raise the loading preparative wholesale device hopper.

[0009]

In the means of the present invention constructed as described above, the caster c in which the bracket 12 is assembled to the machine frame 2 of the grain hopper H is the free wheel 1 at the lower end of its supporting leg 11.
When the weight of the grain hopper H is supported by 0, the load due to the load is very close to the columns 20 of the machine casing 2 ...
The connecting rod 1 of the bracket 12, which is bridged between the lower surface of the bracket 2 and
The connecting points of the upper and lower engaging pins 125 and 126 of 24 are moved horizontally.
The bottom girder 21 and the intermediate girder 22 of the machine casing 2 are extremely strong in the horizontal direction, so that the deformation of the machine casing 2 caused by the load acting on the connecting point can be effectively prevented.

Therefore, the caster c is the grain hopper H.
The machine frame 2 of the grain hopper H can be assembled into the machine frame 2 of the grain hopper H almost without considering the deformation of the machine frame 2 itself and the columns 20 of the machine frame 2.
