Description

Carrying and alighting device for grain transport vehicle}

The present invention relates to a carrying and alighting device for grain transport vehicle for loading or unloading a grain-like load such as cuticles, sawdust, etc. of various grains and grains into a loading box of a transport vehicle. In more detail, by using the driving force of the suction fan, it is possible to automatically load the grain and the skin of the grain, sawdust, etc. into the loading box of the transport vehicle, and also to automatically load the contents loaded by means of the discharge conveyor. It relates to a loading and unloading device for a grain conveying vehicle designed to be unloaded.

Conventionally, when loading the grain and the skin of the grain or sawdust, etc. in a transport vehicle, using a means such as a conveyor provided separately, when loading and unloading the contents loaded by a worker shovel or other Loading and unloading using the tool, which has a long time to work as well as a lot of manpower has to be put into the loading and unloading of grain and sawdust.

The inventors of the present application create a grain loading and unloading device of a grain conveying vehicle which has eliminated all the problems of the conventional loading and unloading operation, which has been made as described above, and has been registered as patent No. 156775. The engine is provided separately from the loading box, and the air suction device and discharge screw driven by the engine are installed in the loading box so that various loads can be loaded into the loading box by the air suction device driven by the engine. The loading and unloading of the load was carried out by the discharge screw installed at the bottom to improve the efficiency of loading and unloading the grain, its skin and sawdust.

Since the conventional grain loading and unloading device has to be equipped with a separate engine on a loading box, the manufacturing cost is expensive and the appearance of the manufactured grain conveying vehicle was not beautiful, and the engine is exposed to the outside. Due to the high engine backlash and poor start-up in winter, the space for installation of the engine must be secured in the loading box, and the loading space has to be reduced. The engine must be replenished with cooling water and various oils from time to time. Therefore, there have been many closures such as the maintenance is quite complicated.

In addition, when loading sawdust using a conventional grain loading and unloading device, the loading operation does not cause any problems, but the loaded sawdust is sharply crushed fine particles, which are easily entangled between the grains and discharged to unload it. There was a problem that only sawdust in direct contact with the discharge screw was discharged and the remaining sawdust remained as it was, so the unloading operation was not efficient. (The above phenomenon occurred more seriously if the sawdust contained moisture. .)

In practice, the difficulty of the unloading operation by the discharge screw as described above is a situation that occurs in all the loads (rice husk, the skin of various grains) including moisture as well as sawdust.

Therefore, the present invention was created to eliminate all the problems of the conventional loading and unloading apparatus as described above, and by eliminating the need for a separate engine for driving, the exterior of the transport vehicle is beautiful and as much as possible in the loading box of the transport vehicle. The purpose of the present invention is to provide a loading and unloading device for a finished grain conveying vehicle, which can be secured in terms of technical problems, so that the loading of the sawdust and various loads containing moisture can be easily loaded and unloaded.
