Trolley for transporting forest fruits in hilly areas and capable of automatically leveling

Abstract

The invention relates to a trolley for transporting forest fruits in hilly areas and capable of automatically leveling. The trolley consists of a walking drive chassis, a fruit box tray and a hydraulic leveling mechanism. Each crawler belt is provided with two connected side plates, a crawler belt walking frame is connected with the side plates, thrust wheels are connected with the side plates through cross beams and guide wheels by tensioning devices, one ends of two leveling hydraulic cylinders are hinged to the fruit box tray, the other ends of the two leveling hydraulic cylinders are hinged to the crawler belt walking frame, rod cavities of the two leveling hydraulic cylinders are connected with each other, and rodless cavities of the two leveling hydraulic cylinders are also connectedwith each other. When the trolley goes uphill and downhill, a certain angle is formed between the crawler belt walking frame and the horizontal plane, by the gravity of the fruit box tray, a piston rod of one leveling hydraulic cylinder stretches, and a piston rod of the other leveling hydraulic cylinder is shortened. From a hydraulic principle, it can determine that the stretching amounts and the shortening amounts of the piston rods of the two hydraulic cylinders are equal, thus, the fruit box tray is always horizontal, and movement of fruit boxes and injury of fruits due to movement are avoided. The trolley is scientific and reasonable in structure, low in cost and easy to operate.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an automatic leveling trolley used for transporting forests and fruits in hilly and mountainous areas. Background technique [0002] In view of the poor passability of forest and fruit harvesting equipment in hilly and mountainous areas, single form of transportation system, high fruit damage rate, and low quality, research on forest and fruit transport vehicles in hilly and mountainous areas is an important part of improving mechanization and production efficiency in hilly and mountainous areas. . In order to ensure that the fruit is not easily damaged, the fruit box should be kept as horizontal as possible during the transportation between the forests. Therefore, the compensation and leveling of the large slope of the fruit box is the core technology of the fruit transport trolley in hilly and mountainous areas. [0003] Scholars at home and abroad have conducted research...
