Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-3, the present invention provides the following technical solutions: a weed clearing device comprises a frame 1;

the two rotating rods 2 are arranged, the two rotating rods 2 are respectively and rotatably connected with the inner part of the rack 1, a plurality of sliding chutes 3 are annularly arranged on the surface of each rotating rod 2 from top to bottom, each sliding chute 3 is of an arc-shaped structure, and a sliding rod 5 is arranged in each sliding chute 3;

the sliding block 4 is connected inside the sliding groove 3 in a sliding mode, a through hole for accommodating the sliding rod 5 is formed in the sliding block 4, and the sliding block 4 is sleeved outside the sliding rod 5 through the through hole and slides along the sliding rod 5;

one end of the cutter head 8 is connected with the side surface of the sliding block 4, and the other end of the cutter head 8 penetrates through the sliding groove 3 and extends to the outside of the rotating rod 2;

the spring 7 is sleeved outside the sliding rod 5, one end of the spring 7 is connected with one end of the inner wall of the sliding groove 3, and the other end of the spring 7 is connected to the end part of the sliding block 4;

the motor 10 is arranged at the upper end of the frame 1, and the upper ends of the two rotating rods 2 are respectively connected with the output end of the motor 10;

the tool apron 9 is arranged on one side of the rotating rod 2, and a tool groove 11 for accommodating the tool bit 8 is formed in the tool apron 9.

Referring to fig. 1, driven shaft 12 has been run through in the center of bull stick 2, and the shaft hole that holds driven shaft 12 is seted up at both ends about the inside one side of frame 1, and driven shaft 12 is passed to the upper end of bull stick 2 and is extended to the top of frame 1 and be equipped with driven tooth 6, and driven shaft 12 sets up and makes things convenient for bull stick 2 to rotate in the inside of frame 1.

Referring to fig. 1, a motor 10 is arranged between two driven teeth 6, an output end of the motor 10 is connected with a driving tooth 13, side surfaces of the two driven teeth 6 are respectively engaged with two sides of the driving tooth 13, and the two driven teeth 6 are respectively engaged with two sides of the driving tooth 13, so that a single motor 10 drives the two driven teeth 6 to move in opposite directions, and thus the two rotating rods 2 are driven to move in opposite directions, when the rotating directions of the two rotating rods 2 move in opposite directions, the opposite movement means that the rotating directions of the two rotating rods 2 are both deviated between the two rotating rods 2, so that the crushed and crushed weeds can be intensively collected in the frame 1, a collecting bag can be arranged at the bottom end in the frame 1, so that the weeds can be intensively collected after the weeds are crushed, and in the same way, when the rotating directions of the two rotating rods 2 are far away from the two rotating rods 2, the weeds can be thrown to two sides of the frame 1 along with the rotation of the rotating rods 2 after cutting, thus directly spreading the weeds on the external land to flush the waste.

Referring to fig. 1, the tool bit 8 of two bull stick 2 outside settings crisscross each other in the vertical direction sets up, when two bull stick 2 outside tool bit 8 dislocation sets, two bull stick 2 outside tool bit 8 are when rotatory promptly, same horizontal plane contact can not take place for the tool bit 8 of two bull stick 2 outside settings, and 8 collision damage problems of tool bit appear, two tool bits 8 of while dislocation sets are when the dislocation rotates, be favorable to the cutting to weeds, thereby make and twine 8 outside weeds of tool bit, when two bull stick 2 outside tool bit 8 dislocation are mutual, cut off, improve crushing precision.

Referring to fig. 1, the distance from the inside of the blade groove 11 to the surface of the rotating rod 2 is one half to five times the distance that the blade head 8 extends outside the rotating rod 2, at this time, the blade head 8 can be ensured to smoothly enter the inside of the blade groove 11, so as to realize the cutting of weeds, and meanwhile, the problem that the blade head 8 contacts with the blade groove 11 too deeply or too shallowly, and the weeds are gathered at the root of the blade head 8 is avoided.

Referring to fig. 1, the height of the blade groove 11 is one point three times the thickness of the blade head 8, and when the height of the blade groove 11 is one point three times the thickness of the blade head 8, it is advantageous to effectively prevent the weeds wound outside the blade head 8 from entering the blade groove 11, thereby affecting the cutting of the weeds.

The utility model discloses a theory of operation and use flow:

the motor 10 drives the two driven teeth 6 to synchronously rotate through the driving tooth 13, so that when the driven teeth 6 rotate, the two rotating rods 2 are driven to rotate, and when the rotating rods 2 drive the cutter head 8 to rotate at a high speed, when the cutter head 8 encounters a branch or a harder grass root, the cutter head 8 can slide relatively outside the slide rod 5 through the slide block 4, the spring 7 is compressed, the end part of the cutter head 8 can slide in the slide groove 3 for a certain distance through the slide block 4, so that the cutter head 8 can move for a certain distance around the rotating rod 2, the problem that the cutting edge of the cutter head 8 is broken due to hard collision between the cutter head 8 rotating at a high speed and the harder branch and the like in the traditional fixed connection design between the cutter head 8 and the rotating rod 2 is solved, when the cutter head 8 rotates, the cutter head 8 with weeds passes through the cutter groove 11 in the cutter seat 9, weeds are trapped on one side of the cutter seat 9, and the cutter head 8 passes through the cutter groove 11, so that the weeds are cut off.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
