Detailed Description
The invention is further described below with reference to the drawings and examples.
As shown in fig. 1 to 3, the invention comprises a plurality of groups of finger group turnover mechanisms 1, turnover locking mechanisms 2 and buffer mechanisms 3 which are arranged in pairs, and an operating mechanism 4 which is arranged in a cab, wherein the finger group turnover mechanisms 1 are arranged on the upper side of a finger group transmission pipe frame 6, and comprise a mounting frame 11 and a turnover oil cylinder 12 which is obliquely arranged, the tail part of the turnover oil cylinder 12 is positioned in a groove plate 111 of the mounting frame 11 and hinged with the groove plate 111, and the inner ends of a pair of finger groups 5 are respectively hinged with two ends of the finger group transmission pipe frame 6.
The turnover locking mechanism 2 is arranged on the upper side of the finger rod group turnover mechanism 1, the turnover locking mechanism 2 comprises a turnover plate 21, a locking plate 22 and a locking plate reset tension spring 23, the lower side of the turnover plate 21 is welded and fixed on the upper side of the inner end of the finger rod group 5, the front end of a piston rod 121 of a turnover cylinder is hinged with one end of the turnover plate 21 through a hinging seat 122, an adjusting nut 123 is arranged at the rear end of the hinging seat 122, and the starting position of the stroke of the turnover cylinder 12 is convenient to adjust.
The locking plates 22 are respectively arranged on the upper sides of the two ends of the groove plate 111, one end upper side of each locking plate 22 is connected with one end of the operating mechanism 4, one end lower side of each locking plate 22 is respectively hinged with the hinging seats 112 on the upper sides of the two ends of the groove plate 111, and the other end lower side of each locking plate 22 is provided with a locking hook 223. The lock pin 211 is fixed to the other end upper side corner of the inversion plate 21. Both ends of the locking plate return tension spring 23 are hooked on an upper spring pin 221 in the middle of the locking plate 22 and a lower spring pin 223 fixed to the upper end of the vertical plate 31 of the buffer mechanism 3, respectively. The locking plate reset tension spring 23 can not only enable the locking plate 22 to be turned to the initial state, but also enable the locking hooks 221 of the locking plate 22 to firmly buckle the locking pins 211 of the turning plate 21, so that the finger rod group 5 is kept in the vertical folding state, and the transportation of the tedder is facilitated.
The buffer mechanisms 3 are respectively arranged at two ends of the groove plate 111 and comprise a vertical plate 31, a pressure spring 32, a buffer rod 33, a cylindrical pin 34 and a retainer ring 35, wherein the vertical plate 31 is L-shaped, the lower end of the L-shape is fixed at one end of the finger rod group transmission pipe frame 5, one end head of the buffer rod 33 extends out of a supporting hole 311 at the upper end of the L-shape, and the other end head extends out of a supporting plate 113 in the lower side of the groove plate 111; the pressure spring 32 is sleeved on the buffer rod 33, two ends of the pressure spring are respectively abutted against one side of a check ring 35 at one end of the buffer rod 33 and a supporting plate 113 in the groove plate 111, the other side of the check ring 35 is abutted against the cylindrical pin 34, and the cylindrical pin 34 is vertically and fixedly connected with the buffer rod 33 through interference fit, so that the check ring 35 is positioned. When the finger group 5 is turned to the vertical state, one end of the buffer rod 33 abuts against the outer side edge of the turning plate 21 on the outer side of the raised finger group 5. The buffer mechanism 3 increases the damping effect of the vertical tilting of the finger group 5, slows down the impact of the locking pin 211 of the tilting plate 21 into the locking hook 221 of the locking plate 22, and ensures the reliable locking of the finger group 5 in the vertical state.
The operating mechanism 4 comprises a handle 41, two release ropes 42 and a circular ring 43, wherein the handle 41 is placed in a cab, the circular ring 43 is vertically fixed on the longitudinal center of the mounting frame 11, the upper ends of the two release ropes 42 are combined into one piece and then connected with the middle part of the handle 41, and the lower ends of the two release ropes 42 respectively bypass the two sides of the circular ring 43 and then are connected with the upper sides of the inner ends of the corresponding locking plates 22.
