Detailed Description

As shown in figure 1, the novel plant protection weeding machine comprises a towing bracket 1, wherein the towing bracket 1 is arranged behind a rice transplanter, so that a towing mechanism does not need to be purchased independently, and the novel plant protection weeding machine only needs to be towed and hung behind the existing rice transplanter, thereby saving the cost. A plurality of extension mounting rods 5 with different lengths are fixed on the bracket 1 at intervals, and the number of the extension mounting rods 5 is 4 in total in the embodiment and the extension mounting rods are arranged at intervals of one long length and one short length. Install the rotatory weeding mechanism of horizontal axis and the rotatory weeding mechanism of vertical axis respectively around extending installation pole 5, every extends installation pole 5 below and is provided with backup pad 2, backup pad 2 is fixed on bracket 5. Backup pad 2 is in the surface contact of paddy field for bear the weight of weeding mechanism on the whole carriage 1, for the convenience of whole mechanism walks in the paddy field, and 2 front ends of backup pad stick up, and the tail end is equipped with the sawtooth. The space between two adjacent supporting plates 2 of the utility model is adapted to the space between the seedlings, so that the whole mechanism can weed in the process of transplanting rice seedlings. In addition, the weeding mechanism can keep consistent with the track during rice transplanting, so that the existing unmanned operation is convenient, and weeding can be synchronously performed in the field only by tracking the track route during rice transplanting.

As shown in fig. 1 and 4, the horizontal axis rotating weeding mechanism comprises a U-shaped frame installed at the front end of an extending installation rod 5, a horizontal grass scraping barrel is installed in the U-shaped frame, and the horizontal grass scraping barrel comprises a horizontal rotating barrel shaft 7 rotatably connected in the U-shaped frame and rotating twisted cutter teeth 8 evenly distributed on the barrel wall of the horizontal grass scraping barrel at intervals. Rotatory distortion sword tooth 8 is the rectangle blade of horizontal direction spiral distortion, and at the in-process that weeding mechanism gos forward, weeds can stretch into between the rotatory distortion sword tooth 8, drives rotatory distortion sword tooth 8 through horizontal rotary drum axle 7 and rotates to weed.

As shown in fig. 1 and 3, the vertical axis rotating weeding mechanism comprises horizontal mounting support arms symmetrically fixed at the left and right sides of the extension mounting rod 5, a rotatable vertical rotating shaft 12 is arranged on the horizontal mounting support arms, a circular truncated cone-shaped rotating cutter head 6 is fixed below the vertical rotating shaft 12, and grass scraping cutter teeth 13 are fixed on the outer wall of the rotating cutter head 6 in the circumferential direction. In the embodiment, the grass scraping cutter teeth 13 are in a diamond-like shape, and the weeding efficiency can be effectively improved due to the irregular shape. In addition, in order to adjust the positions of the rotary cutter head 6 and the grass scraping cutter teeth 13 conveniently and adapt to the conditions of weeds in different fields, the horizontal installation support arm is provided with a strip-shaped installation hole 16, the vertical rotating shaft 12 is fixed in the installation hole 16 through a nut 15, and therefore the horizontal installation support arm can be fixed at different positions in the installation hole 16 through the nut 15.
