Field of the Invention [0001] The present invention relates to an outer ring track type electric vehicle for agricultural use, and more particularly, to an agricultural road type electric vehicle having an outer ring raceway type electric motor for carrying articles by traveling along a road or a road through electric running of the outer ring raceway The present invention relates to a vehicle.

Generally, many farms are cultivating crops in seasonal greenhouses to increase farm income.

These greenhouses form an elongated passageway in the center of the structure and grow crops on both sides of the passageway, so that they can transport the harvested crops as well as the items (fertilizer, compost, etc.) .

Since such a wheelchair has one wheel that rotates the ground, it has an advantage that it can smoothly move a narrow passage in a field or a plastic house.

In fact, the reality of rural areas in Korea is aging because there are few young people. Therefore, it is one of the things that should be improved rapidly in the reality of aged rural areas, The worker's hard labor is required.

In order to solve these problems, Korean Utility Model Registration No. 165219 and the like disclose various transportation vehicles equipped with a small engine or a motor.

However, since the conveyance vehicle is configured so that the drive wheels directly roll in a state of close contact with the ground, it is difficult to smoothly travel in a mud section where the hardness is not high, and it is difficult to pass the section having a high degree of slope or a slippery .

In other words, since all the loads of the objects in the loading space are placed on the wheels, if there is a lot of sand on the ground, or if they are not hardened, they will not roll well and will have a lot of strength. In order to keep the center of the wagon stable, It takes a lot of power.

Particularly, since the carrier car has high load components such as a battery and an electric motor mounted on the vehicle body for power transmission, the problem is further exacerbated by the load of the electric motor or the battery.

An object of the present invention, which is devised to overcome the above-described problems, is to improve a performance of the outer ring raceway by loading various kinds of articles in a loading space and traveling along the road or the road through electric running of the outer ring raceway, The present invention provides an agricultural railroad track-type electric vehicle capable of traveling in a state in which the outer ring orbit is stably stuck to a ground having various heights and shapes, and furthermore, shocks caused by collision with an obstacle are buffered during traveling to provide enhanced driving stability. .
