Detailed Description

The present invention will be further described with reference to the accompanying drawings.

An orchard weeding robot as described in figures 1 to 4 comprises a vehicle body 1 with drive wheels and two cutting blades 2. A motor for driving the driving wheel to rotate is arranged in the vehicle body 1. Two vertical rotating shafts 3 are arranged in the vehicle body 1, and the vertical rotating shafts 3 are driven by a driving mechanism to horizontally rotate. Two vertical rotating shafts 3 are arranged along the length direction of the vehicle body 1, so that the cutting blades 2 arranged below the two vertical rotating shafts 3 are also arranged along the length direction of the vehicle body 1.

The lower extreme of vertical pivot 3 is provided with spacing ring 4, the below of spacing ring 4 is provided with screw thread erection column 5. Two all be provided with mounting hole 6 on the cutting blade 2, two cutting blade 2 cup joints through mounting hole 6 on the screw thread erection column 5, it has fastening nut 7 to go back the spiro union on the screw thread erection column 5, fastening nut 7 with the spacing ring 4 corresponds presss from both sides tightly fixedly cutting blade 2. The cutting blade 2 is mounted in such a way that the cutting blade 2 is easy to disassemble for maintenance.

The cutting blade 2 is long, and the shape and the length of the two cutting blades 2 are the same. The mounting hole 6 sets up cutting blade 2's center department, cutting blade 2's both ends are provided with cutting edge 8 respectively, cutting edge 8's extending direction with cutting blade 2's length direction is certain angle slope. The cutting blade 2 horizontally rotates in the advancing process of the vehicle body 1, and the cutting effect of the oblique cutting edge 8 is better. The length of cutting edge 8 is one fifth to one fourth of cutting blade 2 length, and cutting edge 2 is difficult more impaired, and life is longer, also maintains more easily. If the cutting edge 8 is provided in the middle of the cutting blade 2, the working efficiency of the middle cutting edge 8 is also low. Due to the fact that the length of the cutting edge 8 is set, the weeding effect of the single long-strip-shaped cutting blade 2 is poor, and partial weeds can be missed when the cutting blade 2 at the front end of the vehicle body works, therefore, the two cutting blades 2 are arranged, the cutting blade 2 at the rear of the vehicle body can weed for the second time, the missed weeds can be avoided, and the weeding effect of the weeding machine is improved.

As shown in fig. 2, the distance between the centers of the two vertical rotating shafts 3 is smaller than the length of the cutting blade 2, and the rotating speed and the rotating direction of the two vertical rotating shafts 3 are the same. When one of the cutting blades 2 is rotated to be parallel to the longitudinal direction of the vehicle body 1, the other cutting blade 2 is perpendicular to the longitudinal direction of the vehicle body 1. Thereby make two cutting blade 2 cutting area can partially overlap, and then reduced the automobile body space that two cutting blade 2 occupy, the structure sets up more rationally.

Be provided with driving motor 9 on the automobile body 1, be provided with drive gear 10, two on driving motor 9's the output shaft the upper end of vertical rotating shaft 3 all is provided with driven gear 11, and the number of teeth of driven gear 11 on two vertical rotating shafts 3 is the same, drive gear 10 meshes the transmission with two driven gear 11 simultaneously, and driving motor 9 can drive two vertical rotating shafts 3 simultaneously and rotate, and the structure is retrencied more, has also ensured that 3 direction of rotation and the slew velocity of two vertical rotating shafts are the same simultaneously.

The lower surface of spacing ring 4 is provided with reference column 12, cutting blade 2 go up be provided with reference column 12 corresponds the locating hole 13 of pegging graft, ensures that cutting blade 2 can not rotate with vertical pivot relatively.

The below of automobile body 1 is provided with protective housing 14, two cutting blade 2 are established to protective housing 14 correspondence cover, improve cutting blade 2's security.

A forage outlet 15 is formed in one side, close to the rear end of the vehicle body 1, of the protective housing 14, and accordingly cut weeds can leave the protective housing 14 conveniently.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the utility model and these are intended to be within the scope of the utility model.
