It should be noted that the invention relates to a hammer throw type cutter mechanism for a weeding robot, which has the following working principle:
the cutter protection function means: when the whole cutter is connected to the power moving platform through the quick-change connecting plate 102 to start working, the position of the sliding shoe 202 is a distance ahead relative to the working cutter 3 in the advancing direction, that is, when there is a large and wide steep slope terrain in front of the working cutter 3, the shape of the sliding shoe 202 can cause the whole cutter frame 1 to ascend or descend along with the terrain change to change the angle, so that the auxiliary round stick 101 which is ahead of the cutter frame 1 cannot be sunk into the steep slope soil and is difficult to extract, and meanwhile, the ground roller 201 which is located at the rear part of the working cutter 3 plays a role in rear support, so that the sliding shoe 202 and the ground roller 201 form a group of more stable supporting structure.
The auxiliary cutting function of the ground roller is as follows: after the working cutter 3 is started, the working cutter 3 forms an integral cutting cylindrical surface when in work, namely a cutting circle when viewed from the side surface, the sum of the radius of the cutting circle and the maximum radius of the ground roller 201 is slightly smaller than the center distance between the working cutter 3 and the ground roller 201, and meanwhile, the axis of the ground roller 201 and the axis of the working cutter 3 are parallel, so that if the working cutter 3 encounters vine vegetation with stronger toughness when in work, the vine vegetation can be brought into the cutter frame 1 through the hammer-shaped flail knife 303, a longer shearing space can be formed through the relative speed difference and the position gap between the cutting circle and the ground roller 201, a shearing stress force is formed on the curled vine vegetation, and the vine vegetation is sheared to realize an auxiliary cutting function.
The cutting function means: after the working cutter 3 is started, the hammer flail knives 303 hinged on the working cutter 3 overcome self gravity along with the centrifugal force action transmitted by the flail knife roller 301 along the flail knife installation seat 302, the posture of the vertical ground is changed into the vertical posture collinear with the radius direction of the flail knife roller 301, along with the layout of the plurality of flail knives, the working cutter 3 forms an integral cylindrical face-shaped cutting face through the cutting edges of all the hammer flail knives 303 when in work, the cutting face can be regarded as a cutting circle when being observed from the axial visual angle of the working cutter 3, and the radius of the cutting circle is the distance from the cutting edges of the hammer flail knives 3 in the vertical state to the axis of the working cutter 3.
The motor position adjusting function means: after the cutter driving motor 5 is mounted on the movable hinge plate 402 of the motor mounting seat 4, the fixed hinge plate 401 is fixed on the cutter frame 1 through bolt thread connection, so that the cutter driving motor 5 only has a degree of freedom of axial rotation controlled by the adjusting bolt 404 and the adjusting nut 405, wherein a threaded hole for mounting the adjusting bolt 404 is formed in a corresponding position of the movable hinge plate 402, a thread with a certain length is exposed after the adjusting bolt 404 is matched with the adjusting nut 405 to be matched with a corresponding threaded hole in the movable hinge plate 402, because the length of the thread of the adjusting bolt 404 is much greater than the thickness of the movable hinge plate 402, when the adjusting nut 405 is loosened to allow more lengths of the adjusting bolt 404 to be matched with the movable hinge plate 402, one surface of the adjusting nut 405 contacts the movable hinge plate 402 to complete adjustment, at this time, a part of the thread of the adjusting bolt 404 exceeds the movable hinge plate 402 to contact the cutter frame 1, namely, the adjusting bolt 404 supports the movable hinge plate 402 and the cutter driving motor 5, and the adjusting position of the cutter driving motor 5 can be realized only by loosening the adjusting nut 405 to control the adjusting the threaded hole between the adjusting bolt 404 and the movable hinge plate 402.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
