Description
Technical Field
The utility model relates to an agricultural production apparatus specifically is a light laborsaving forward type agricultural small handcart.
Background
During operations such as fertilizing, irrigating, picking and the like in farmlands, orchards or nurseries, the single-wheel barrow is mostly used for carrying goods or materials, and the single-wheel barrow is electric, motor-driven and manual. However, the basic structure of any wheelbarrow is the same, namely a wheelbarrow with a frame arranged on one wheel and a pair of hand grips arranged on the frame, and the hand grips are held by two hands when the wheelbarrow is used. The motor or the engine is electrically or mechanically mounted on the frame, and the transmission is connected with the wheels through a speed changer and the like. The frame bears materials, the hand grips with both hands to advance, and due to uneven ground and different hardness, the vehicle is inclined and even overturned frequently. In order to ensure the stable running, the user needs to exert force to balance the pressure caused by the shift of the center of gravity, so that the user is more strenuous. The force is more strenuous when the mountain land with the slope is marched.
In addition, the arrangement of the power mechanism and the frame of the existing monocycle is not reasonable, the center of gravity is concentrated at the middle rear part when the monocycle is unloaded, and both hands still need to separate a part of force to lift the handlebar grip when carrying objects, so that great labor is consumed. Therefore, there is a need for further improvements in such wheelbarrows.
