Description

[Detailed Description of the Invention] The present invention was developed for the purpose of providing a transport vehicle that can easily scoop out loaded items such as feed from the side wall using a shovel.

Conventional feeding vehicles, etc. that transport feed have a loading capacity of 200 to 30
It has a large rectangular box-shaped packet weighing up to 0 kg, and is commonly used with two wheels in the front and a unicycle such as a caster in the rear, but the contents of this type are scooped out from the side with a shovel. In addition, it was difficult to attach the shovel to the side, and the packet was unstable due to its movement, which caused the shovel to strain and become extremely inconvenient.

The requirements for a distribution box include firstly, the lower the packet is, the easier it is to apply force when scooping out the contents using a shovel, and the closer the edge of the scoop is to the side wall, the easier it is to scoop out the contents.

Of course, it is also necessary that the vehicle body does not move.

However, even though it is said that the lower the packet is, the better it is, if the wheels are small or the ground is in poor condition, extra force is required to transport it.
It also vibrates heavily, making it difficult to use.

Therefore, it is better to use wheels as large as possible.

Naturally, it is also necessary to be able to easily change direction during transportation.

The above-mentioned problems have been solved by the four-wheeled transport vehicle of the present invention, and its features are (1) the slope of the side wall of the packet is made gentler, making it easier to scoop with a shovel, etc.; (2) The stability of the packet was increased by using a fixed four-wheeled vehicle, and (3) the handle was installed almost perpendicular to the pusher frame to slightly lift the vehicle body when changing direction. There is a particular thing.

The present invention will be further explained in detail with reference to the drawings below.

Fig. 1 is a rear view of a four-wheeled transport vehicle showing the first embodiment of the present invention, Fig. 2 is a side view of the same, and Fig. 3 is a second embodiment showing the shape of the packet. FIG.

In Fig. 1, the side walls 1 on both sides of the packet have a gentle slope α, and as shown in Fig. 3, one side wall 1 has a gentle slope α, and the other side wall has a steep slope β. It can also be used as a.

When the side wall is provided with such a gentle slope, that is, α-45 to α-20, it is easy to scoop up the contents with a shovel, and since the top surface is wide, the contents do not spill out.

Packet is F'RP (glass fiber reinforced plastics)
It is preferable to coat both sides of a manufactured or punched metal plate with the above-mentioned FRP because it has an elegant appearance and has good corrosion resistance and durability.

Two axles 5 are fixed to the bottom of the packet with buttons, and wheels 2 are provided at both ends of each via bearings, making it a four-wheeled vehicle.

By using a four-wheeled vehicle, the contents of the packet do not shake when scooping with a shovel, etc., and the overall structure can be lower than that of a wheeled vehicle.In addition, the large wheels can be used, so the pushing force is light.
It has good stability.

FIG. 4 is a rear view showing the third embodiment. In this example, the wheels 2 are attached by fixing an independent axle bracket 6 to the bottom of the side wall 1, and each wheel 2 is attached to the axle bracket 6. As shown in Fig. 1, the packet position is low and stable, making it easy to unload with a shovel.

In order to solve the difficulty of changing the direction of the vehicle body, which is a drawback of four-wheeled vehicles, the handle 4, which is one of the features of the present invention, is fixed to the rear of the packet as shown in Figure 2. It is fixedly provided rearward to the pusher frame 3 in a substantially perpendicular direction.

The mounting direction and position of the pusher frame 3 are arbitrarily determined between the rear and the sides depending on the size and purpose of the carrier.

The direction can be easily changed by pushing the pusher frame 3 while transporting in a straight line, and slightly lifting the handle 4 when changing direction.

Changing direction can be made easier by reducing the distance between the front and rear wheels, that is, the wheel base, as long as stability is not compromised.

Because the four-wheeled transport vehicle of the present invention has the above structure,
It is light and can be transported stably even on rough roads, it is easy to change direction, it can be easily scooped up to the destination with a shovel, etc., and it does not roll over or overturn, especially for delivery vehicles. This is a useful example.
