[0003] The greater the horsepower of the tractor, the greater the lifting force is required. The lifter with the above structure needs to increase the lifting force while increasing the horsepower, the cylinder diameter and the housing need to be increased, which in turn requires the tractor chassis to be enlarged. Increase development difficulty and cost

Embodiment Construction
[0030] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.
[0031] Such as Figure 1 to Figure 3 As shown, the present invention provides a lifting force generating device, which is arranged on a tractor, and is used to lift or lower the agricultural implements towed behind the tractor, so as to use the agricultural implements for operation. The lifting force generating device comprises an outer casing 1, a lifting shaft 13 rotatably arranged on the outer casing 1, an outer lifting arm arranged on the lifting shaft 13, and a main oil cylinder 14 for generating force on the lifting shaft 13. The outer casing 1 It is used to connect with the upper part of t...

The invention discloses a lifting force generating device and a tractor thereof. The lifting force generating device comprises an outer casing, a lifting shaft rotatably arranged on the outer casing, an outer lifting arm arranged on the lifting shaft, and an outer lifting arm for adjusting the lifting shaft. The main oil cylinder for generating force also includes an auxiliary oil cylinder for generating force for the outer lift arm. The lifting force generating device of the present invention can greatly increase the lifting force by adding an auxiliary oil cylinder and cooperating with the main oil cylinder. In this way, if the tractor horsepower is increased, it is not necessary to replace the chassis, and it is not necessary to redevelop the outer shell of the lifter, which greatly reduces the development cost. difficulty and cost.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular, the invention relates to a lifting force generating device and a tractor with the same. Background technique [0002] During the use of the tractor, it is necessary to use a lifter to lift or lower the agricultural implements towed behind the tractor so that the agricultural implements can be used for operations. At present, a semi-separated lifter is mainly used on medium and small-horsepower wheeled tractors in my country. Its structure is simple, including the outer lift arm and the inner lift arm connected together by the lift arm shaft, and the piston rod hinged on the inner lift arm. , the piston rod is connected to the piston of the hydraulic cylinder, the hydraulic cylinder is installed in the sealed lifter housing, and the lifter housing is filled with hydraulic oil. One side of the lifter housing is fixedly installed with a reversing valve. The two oil outle...
