Abstract
The utility model discloses a weeding machine. The weeding machine comprises a rotary power source, a rack, a main rotary shaft, a rotary blade, a rotary roller, a reverse transmission gear set, a forward transmission gear set, a sleeve shaft and a transmission shaft. The main rotary shaft is in rotary connection with the rack, and the rotary blade is arranged on the main rotary shaft. The sleeve shaft is in rotary connection with the rack and is sleeved on the outside of the main rotary shaft and movably connected with the main rotary shaft, and the sleeve shaft is shorter than the main rotary shaft. The rotary roller is arranged on the sleeve shaft, and the main rotary shaft is connected with the rotary power source and is connected with the transmission shaft through a reverse transmission gear set. The transmission shaft is connected with the sleeve shaft through the forward transmission gear set and is movably connected with the rack. The rotary roller comprises a roller sleeve and a plurality of drawing rollers which are perpendicular t the sleeve shaft and arranged on the roller shaft symmetrically. According to the weeding machine, weeds are drawn and pulled and cut off through the drawing rollers rotating reversely, and the weeding effect of the weeding machine is greatly improved through a simple structure.
Description
Technical field
The utility model relates to a kind of weeder, belongs to field of agricultural machinery.
Background technology
The blunt matter blade that passes through that traditional weeder is simple cuts grass, and many times the better grass of Toughness Ratio will be beaten to barocline by blade and cannot clean out on careless face, also can leave more weeds, poor effect after cutting.
Utility model content
The purpose of this utility model is: the technical scheme that can address the above problem is provided.
The utility model is realized by the following method:
A kind of weeder, comprise rotating power source, frame, main shaft and rotating blade, described main shaft and frame are rotationally connected, described rotating blade is arranged on main shaft, described weeder also comprises rotation rod, contrary gear train, positive drive gear train, quill, power transmission shaft, described quill and frame are rotationally connected, described quill is socketed between main shaft outside and is flexibly connected, described quill is shorter than main shaft, described rotation rod is arranged on quill, described main shaft is connected with rotating power source, described main shaft is connected with power transmission shaft by a set of contrary gear train, described power transmission shaft is connected with quill by positive drive gear train, described power transmission shaft is flexibly connected with frame,
Described rotation rod comprises axle sleeve and some traction rods, and described traction rod is installed on axle sleeve perpendicular to quill symmetry;
As further innovation of the present utility model, described positive drive gear train is primary speed-down gear train, and the larger gear of the described primary speed-down gear train number of teeth is connected with power transmission shaft, and the less gear of the described primary speed-down gear train number of teeth is connected with quill.
As further innovation of the present utility model, described power transmission shaft is flexibly connected by bearing with frame.
As further innovation of the present utility model, between described quill and main shaft, by needle bearing, be flexibly connected.
As further innovation of the present utility model, described rotating power source is diesel engine.
As further innovation of the present utility model, described traction rod is woollen goods material.
As further innovation of the present utility model, the quantity of described traction rod and the knife number of rotating blade equate.
Beneficial effect
1. the first traction tension that the utility model arranges counter-rotational traction rod realization grass by the knife rest top of the large-scale weeder traditional is cut off again, by simple structure, improve greatly the herbicidal effect of weeder, there is good social benefit and significant technological progress.
2. the utility model is by primary speed-down Zeng Niu gear train mechanism is set, thereby the rotating speed of the traction rod that slows down improves the moment of torsion of traction rod, thereby the traction weeds that it can be more firm and strong are cut off, and realizes the object of weeding.
3. power transmission shaft of the present utility model is realized support by needle bearing, has utilized the effect of the anti-cross force of needle bearing, has improved the rotational stability of traction rod and blade.
4. traction rod of the present utility model adopts woollen goods material to increase the adhesion of durability and blade of grass, has improved the effect of weeding.
5. the traction quantity of rod and the quantity of rotating blade equate, have guaranteed the rotational stabilization of system, have improved the efficiency of weeding.

Embodiment
Below in conjunction with accompanying drawing, be described further
As shown in Figure 1 and 2: a kind of weeder, comprise diesel engine 1, frame 5, main shaft 2 and rotating blade 4, described main shaft 2 and frame 5 are rotationally connected, described rotating blade 4 is arranged on main shaft 5, described weeder also comprises rotation rod, contrary gear train 7, primary speed-down gear train 8, quill 3, power transmission shaft, described quill and frame 5 are rotationally connected, described quill 3 is socketed between main shaft 2 outsides and is flexibly connected, described quill 3 is shorter than main shaft 2, described rotation rod is arranged on quill 3, described main shaft 2 is connected with the output shaft of diesel engine 1, described main shaft 2 is connected with power transmission shaft by a set of contrary gear train 7, described power transmission shaft is connected with quill 3 by primary speed-down gear train 8, described power transmission shaft is flexibly connected with frame 5,
Described rotation rod comprises axle sleeve 9 and some traction rods 6, and described traction rod 6 is installed on axle sleeve 9 perpendicular to quill 3 symmetries;
Wherein between quill 3 and main shaft 2, quill 3 and frame 5, between main shaft 2 and frame 5, by needle bearing, connect;
The quantity of described traction rod 6 is identical with the quantity of rotating blade 4, and traction rod 6 adopts woollen goods material to make.
After startup, the direction of rotation of rotation rod and rotating blade 4, rotate rod first because the frictional force of self by grass with respect to the blade reverse of rotating blade 4 to tension, thereby improve the efficiency that rotating blade is mowed, thereby the operating efficiency that improves weeder, has good social benefit.
