The rear end of the movable frame 4 is hinged with the rear end of the second frame 22 of the seat frame 2 through a long pin shaft 16, the front end of the movable frame 4 is hinged with the mower frame 1, specifically, two longitudinally extending mounting pieces 5 are arranged on a cross rod of the mower frame 1, and the front end of the movable frame 4 is arranged between the two mounting pieces 5 and is in running fit through a bolt.
A first spring group 6 is provided between the front end of the movable frame 4 and the seat frame 2 (i.e., the front side of the second frame 22); the first spring group 6 comprises two longitudinally mounted springs which are respectively arranged at the left side and the right side; a second spring group 7 is arranged between the rear end of the seat frame 2 and the mower frame 1, and the second spring group 7 also comprises two springs which are longitudinally arranged, in particular two support beams 1a which extend forwards and backwards and are respectively arranged on the mower frame 1. Therefore, the front end and the rear end of the mower seat can move and extrude the spring, and the effect of damping and buffering is provided by means of the elastic restoring force of the spring.
In order to limit the movable fit between the movable frame 4 and the seat frame 2, the maximum movable distance between the movable frame 4 and the seat frame 2 is limited. A limiting mechanism 8 is arranged between the movable frame 4 and the seat frame 2. Specifically, stop gear 8 includes: a stopper pin 81 provided at a side wall of the seat frame 2 and extending laterally; and a limit ring 82 fixed on the side wall of the movable frame 4 and sleeved on the limit pin 81. In order to increase the compression range, the side wall of the movable frame 4 is further provided with an escape groove 83 which is matched with the contour of the inner hole of the limit ring 82. Thus, the stopper pin 81 can move within the range of the escape groove 83 and the stopper ring 82.
In order to reduce the assembly space as much as possible, the structure is made more compact. Referring to fig. 2, the side wall 23 of the seat frame 2 is movable relative to the side wall 41 of the movable frame 4, and is at least partially covered by the side wall 41 of the movable frame 4.
