The invention provides a leveling system for a tomato harvesting machine. The leveling system comprises a chassis, two cross beams, axles, four oil cylinders, a control system and an oil path system, wherein the middle parts of the cross beams are fixed on the chassis; the axles are hinged to the bottom of the chassis and used for connecting wheels; the control system is used for controlling the oil cylinders; the four oil cylinders include a left front oil cylinder, a right front oil cylinder, a left rear oil cylinder and a right rear oil cylinder; one end of each oil cylinder is hinged to the corresponding end of the two cross beams, and the other ends of the oil cylinders are hinged to the axles. The leveling system for the tomato harvesting machine, provided by the invention, has the advantages of good leveling effect, safety, reliability and high leveling efficiency.
Description
technical field [0001] The invention relates to a tomato harvester leveling system. Background technique [0002] At present, when the domestic self-propelled tomato harvester is in operation, when the body is tilted left and right, the following results will be caused: 1) The fruit rolls laterally when conveying materials, causing the conveyor belt to be unbalanced, resulting in deviation and aggravating the wear of the conveyor belt; 2) Due to the inclination of the body and the lateral movement of the fruit, the material in the color selection area is uneven, resulting in a decrease in the accuracy of the color selection; 3) When the harvester is walking and working on a slope, it is easy to cause a rollover accident due to the excessive inclination of the body. Therefore, it is necessary to accurately level the body of the tomato harvester. At present, the leveling method on the domestic self-propelled tomato harvester is to adjust the levelness of the body through the ...
