Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a vertical lifting device of an agricultural transport vehicle. Background Art

[0002] With the rapid development of science and technology, innovative technology has gradually radiated to the agricultural field, which makes agricultural production no longer dependent on manpower, and production efficiency has been greatly improved. In the current mechanical application process, large-scale equipment is often used to replace manual labor in the sowing, spraying of pesticides, and harvesting of crops. However, large-scale equipment is no longer suitable in some areas with small demand, such as the transportation of a small amount of crops. Agricultural transport vehicles are common small rural transportation equipment, which are very convenient for transporting materials and harvests. However, due to the certain height of the carriage from the ground, existing agricultural transport vehicles such as motorized tricycles do not have the ability to transport materials and harvests from the ground to the carriage of agricultural transport vehicles, which will be very difficult, especially when the materials are heavy. It is difficult for one person to move the heavier materials and harvests into the carriage of the agricultural transport vehicle, and the loading and transportation efficiency is low.

[0003] The patent with the public patent number: CN219769719U discloses a lifting device based on an agricultural transport vehicle, wherein a flap is hingedly arranged on the lower end near the movable frame, and the flap also serves as a rear baffle and can be opened and closed within the range of 0-90 degrees relative to the movable frame; the two ends of the two upper connecting plates are respectively hinged to the middle and upper parts of the fixed frame and the movable frame, and the two ends of the two lower connecting plates are respectively hinged to the middle and lower parts of the fixed frame and the movable frame; one end of the two steel wire ropes is respectively fixed to the middle part of the upper connecting plate, and the other end is wrapped around the steering pulley and fixed on the winch.
