Detailed Description

Example one

As shown in fig. 1 to 6, the tea and orchard weeding machine of the embodiment has a frame supported on a copying wheel 1 and a driving wheel 15. An engine 10 and a transmission 14 for transmitting power are arranged on a frame above a driving wheel 15, a multi-stage speed change gear 14-3 is arranged in a transmission case 14-2 of the transmission 14, a sliding gear is connected with a shift fork 14-1 and further connected with the lower end of a shift rod 17, and therefore the forward three-gear and backward two-gear speed change gear shift control is achieved. Because of the integrated design of speed change and gear shift, the structure is compact, which is beneficial to miniaturization.

A cutter shaft assembly 13 supported on the frame is arranged between the profiling wheel 1 and the driving wheel 15, as shown in fig. 7 and 8, a cutter shaft main body 13-1 is supported on the frame through a left bearing seat 13-3 and a right bearing seat 13-6 respectively positioned at two ends, and one end is connected with a corresponding power output end of a gearbox 14 through a cutter shaft transmission belt pulley 21. The main body 13-1 of the cutter shaft is provided with three groups of mowing knives 13-2 which are uniformly distributed in the circumferential direction and axially spaced, and the axial directions of the mowing knives 13-2 are mutually staggered. Each mowing knife 13-2 is composed of a herringbone knife body, the handle part of the herringbone knife body is hinged on a corresponding knife seat extending outwards in the radial direction of the knife shaft main body 13-1 through a knife shaft connecting bolt 13-9, and the flail knife type knife shaft of the embodiment can finish efficient weeding without leakage.

The frame above the cutter shaft assembly 13 is provided with a horizontal rotating seat 9, and the armrest frame 8 is arranged on the rotating seat 9. The structure is that the lower end of the handrail frame 8 is hinged with a boss on the rotating seat 9 at the position close to the rotating center of the rotating seat 9, the lower section of the handrail frame 8 is hinged with the upper end of the positioning rod 9-1, and the lower end of the positioning rod 9-1 is provided with a hook head which is hooked and locked with one end of the rotating seat 9 far away from the rotating center. Therefore, when the armrest frame is rotated, the positioning rod can be firstly released, the rear end of the armrest frame is lifted to avoid interference, then the armrest frame is rotated, and then the positioning rod is hooked and locked again. Like this, 180 transposition can be realized through the roating seat to the handrail frame as required to the operation of walking towards normal advancing direction, or the operation of walking against normal advancing direction after the transposition (see fig. 1 dotted line show), needn't turn to, thereby strengthen the flexibility and the adaptability of this embodiment weeder greatly, make things convenient for the mechanized weeding operation in tea garden, orchard.

In addition, the weeder of this embodiment can adjust the arbor height through spiral arbor height adjustment assembly 7 to adjust and mow the stubble height of staying. Other structural features can be easily understood by the detailed drawings and the names of the parts, and are not described in detail.
