Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure, as the terms used are used to describe particular embodiments only, and are not intended to limit the exemplary embodiments based on the disclosure.
Fig. 1 shows, the utility model relates to a leading hoist mechanism of tractor, including hydraulic cylinder 1, hydro-cylinder bracing piece 2, two lift arms 3, lift arm connecting rod 4 and two vertical lifting support 6 of placing and being parallel to each other. The oil cylinder supporting rod 2 is horizontally fixed at the upper part between the two lifting brackets 6, and the lifting arm connecting rod 4 is horizontally placed at the lower part between the two lifting brackets 6. The two lifting arms 3 are fixed at two ends of the lifting arm connecting rod 4 and extend forwards, and the rear ends of the lifting arms 3 extend backwards of the lifting arm connecting rod 4 to form an oil cylinder connecting arm 5. The hydraulic oil cylinder 1 is vertically arranged, the upper end of the hydraulic oil cylinder 1 is connected to the oil cylinder supporting rod 2, the lower end of the hydraulic oil cylinder 1 is connected to one of the oil cylinder connecting arms 5, and the hydraulic oil cylinder 1 is preferably a double-acting hydraulic oil cylinder. The lift arm link 4 is able to rotate along its axis. The rear parts of the two lifting brackets 6 are provided with fixing parts for fixing the lifting brackets 6 to the front axle bracket. The fixing member may be a bolt hole 61 formed in the rear portion of the lifting bracket 6, a screw hole matching the bolt hole 61 is formed in a portion of the front axle bracket to which the lifting bracket 6 is fixed, and a bolt is inserted through the bolt hole 61 and screwed into the screw hole to fix the lifting bracket 6 to the front axle bracket. The fixing element can also be another element that can be used for fixing in the prior art.
The hydraulic oil cylinder 1 drives the oil cylinder connecting arm 5 to descend, so that the lifting arm 3 swings upwards; on the contrary, the hydraulic oil cylinder 1 drives the oil cylinder connecting arm 5 to descend, and the lifting arm 3 can swing downwards. The utility model discloses simple structure, easy to operate. Setting up of double-acting hydraulic cylinder can make the utility model discloses realize strong lift by force lifting function, the working process is not fragile, the fault rate is low.
