A first fixing block 142 is arranged at the rear of the casing 14, a threaded hole is formed in the first fixing block 142, a first fixing screw 144 is connected to the threaded hole in a threaded manner, and the fixing block 142 is fixed on the rack through the first fixing screw 144. A sealing cover 143 is arranged in front of the shell 14, and the sealing cover 143 can be detached to facilitate the maintenance of internal parts when the weeder is damaged. Two output ends 145 which are symmetrically distributed are arranged below the shell 14, the included angle of the two output ends 145 is 60 degrees, a second fixing block 146 is arranged outside the output ends 145, and a threaded hole is formed in the second fixing block 146.

Weeding mechanism 2 is including setting up lag 21 in second output 145 below, and the one end that lag 21 is close to output 145 is provided with sealing washer 211, and the outside is opened and is had the fixed orifices 212 in the sealing washer 211, is provided with second set screw 26 in the fixed orifices 212, and second set screw 26 passes the screw hole cooperation of fixed orifices and second fixed block 146 and fixes lag 21 at output 145. The transmission shaft 22 is arranged in the protective sleeve 21, a second bevel gear 23 is arranged at one end, close to the shell 14, of the transmission shaft 22, two second sealed bearings 221 which are distributed in parallel are arranged on the transmission shaft 22, and the second bevel gear 23 arranged on the transmission shaft 22 is meshed with the first bevel gear 13. And the two second bevel gears 23 mesh.

As shown in fig. 1, 3, 4 and 5, a weeding disk 24 is arranged below the protecting sleeve 21, a through hole 243 is formed in the upper middle of the weeding disk 24, a fixing nut 25 is arranged below the weeding disk 24, the fixing nut 25 is in threaded connection with the lower end of the transmission shaft 22, the weeding disk 24 is fixed on the transmission shaft 22, and the lower end of the transmission shaft 22 is of a boss structure so that the weeding disk 24 can be axially fixed.
