Abstract
The utility model relates to a gardening tool, particularly a cutting mechanism of a lawn mower. The utility model is provided with a circular column helical revolving knife and a straight knife, wherein the circular column helical revolving knife is composed of a revolving knife shaft, helical revolving knife blades, and positioning plates, at least three blocks of the positioning plates are fixedly connected with the revolving knife shaft, at least three strips of the helical revolving knife blades are fixedly connected with the positioning plates and a knife edge of the straight knife is in contact with an omnibus rod of the circular column helical revolving knife or proper gaps are remained between the knife edge of the straight knife and the omnibus rod of the circular column helical revolving knife. The cutting mechanism of a lawn mower of the utility model has the advantages of small wound of sheared grass, small damage to the grass, and high safety; furthermore, the utility model lowers the requirements of material of the knife blades and processing technology and an integral structure is simple.
Description
Affiliated technical field
The utility model relates to garden instrument, especially the cutting mechanism of mower.
Background technology
At present, well-known mower blade is in the majority with orbiting vane.This type of mower blade is with the normal direction main shaft high speed rotating of impeller shape blade around it, thereby grass is interrupted.Yet, by high-speed rotating impeller shape blade grass is interrupted and can cause grass to form bigger wound at incision position.And, very high because the blade of high speed rotating has very big nocuity in case fracture flies out thereby the material of blade and processing technology require, also high to the requirement of shelter of rotating knife.
Summary of the invention
The utility model provides a kind of mower cutting mechanism, hobboing cutter in this mechanism is simple and reliable for structure, and the material and the processing request thereof of blade are relatively low, and hobboing cutter rolls on straight knife and forms the sheared edge of continuous folding, just can realize shearing under lower rotating speed, safety is higher.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of mower cutting mechanism, have cylindrical screw hobboing cutter and straight knife, the cylindrical screw hobboing cutter is made up of cutter shaft, spiral hobbing cutter sheet, location-plate, at least three location-plates are fixedlyed connected with cutter shaft, article at least three, the spiral hobbing cutter sheet is fixedlyed connected with location-plate, and the blade of straight knife contacts with the bus of cylinder hobboing cutter or stays appropriate gap.
Further, the installation requirement of cutter shaft, spiral hobbing cutter sheet and location-plate: the axis of described cutter shaft is vertical with the location-plate plane; The axis of screw of spiral hobbing cutter sheet and the axis coaxle of cutter shaft and spiral hobbing cutter sheet are evenly distributed on the axis circumference.
In order to reach best cutting effect, particularly: described location-plate quantity is three, respectively fixedly the two ends of spiral hobbing cutter sheet and middle part; The quantity of described spiral hobbing cutter sheet is six, the bus gap≤0.15mm of the blade of straight knife and cylinder hobboing cutter.
The beneficial effects of the utility model are:
1. the wound of the grass of cutting off is little, and is little to the damage of grass;
2. safety is good, has reduced the requirement of the material and the processing technology of blade;
3. overall structure is simple.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
1. cutter shafts among the figure, 2. location-plate, 3. spiral hobbing cutter sheet, 4. straight knife.
Embodiment
A kind of mower cutting mechanism as shown in Figure 1 and Figure 2 has cylindrical screw hobboing cutter and straight knife 4, the cylinder hobboing cutter is made up of cutter shaft 1, location-plate 2 and spiral hobbing cutter sheet 3, at least three location-plates 2 are fixedlyed connected with cutter shaft 1, article at least three, spiral hobbing cutter sheet 3 is fixedlyed connected with location-plate 2, and the blade of straight knife 4 contacts with the bus of cylindrical screw hobboing cutter or stays appropriate gap.The axis of cutter shaft 1 is vertical with location-plate 2 planes, and the axis coaxle and the spiral hobbing cutter sheet 3 of the axis of screw of spiral hobbing cutter sheet 3 and cutter shaft 1 are evenly distributed on the axis circumference.In order to reach best cutting effect, location-plate 2 quantity are three, the fixedly two ends of spiral hobbing cutter sheet 3 and middle part respectively, and the quantity of spiral hobbing cutter sheet 3 is six, the bus gap≤0.15mm of the blade of straight knife 4 and cylinder hobboing cutter.
During work, the cylindrical screw hobboing cutter forms sheared edge around cutter shaft 1 rotation with straight knife 4, pushes ahead in the process at mower and constantly the grass under the cylindrical screw hobboing cutter is cut, and Cutting Length is realized by the roller setting height(from bottom) of regulating the mower bottom.
