Description
Technical field
The utility model relates to agricultural machinery cutting-tool engineering field, especially a kind of broken branch weeding knife being widely used in agricultural production.
Background technology
Branch trimmer and lawn mower etc. be a kind of for cutting the grass on a lawn, the machine tool of branch etc.They are made up of parts such as cutterhead, engine, road wheel, running gear, blade, handrail, controls.Blade utilizes the high-speed rotary of engine to transfer and builds lawn and branch, saves the activity duration of workman, decreases a large amount of human resources.As the important component part of branch trimmer and lawn mower, traditional broken branch weeding knife complex structure, there is pruning and weeding ratio not high, the shortcomings such as agricultural production efficiency is low.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of structure simple, can improve the agricultural machinery cutter of agricultural production efficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of broken branch weeding knife, there is cutterhead, described cutterhead edge is provided with multi-disc blade around the center of circle, blade comprises integrated installation portion and operate portions, 1/2 place of described operate portions is bent into L shape, the both sides of operate portions are provided with blade, are provided with a plurality of reinforcements between blade, and blade width is 8-12mm; Described cutter head center offers installing hole, installing hole offers many stopper slots, and adjacent two stopper slot centre distances are 5-8mm; Described stopper slot bottom adhe has antiwear projection.
Further, described installation portion is arranged on cutterhead by screw.
Further, described adjacent two stopper slot centre distances are 5mm
Further, described blade width is 10mm.
Further, described projection is rubber projection.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, good cutting effect, and intensity is high, effectively can improve pruning and weeding ratio, improve agricultural production efficiency simultaneously; Projection bottom stopper slot forms certain space between rotating shaft and stopper slot, slows down the wearing and tearing of rotating shaft to stopper slot.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. installation portions, 2. operate portions, 3. blade, 4. screw, 5. reinforcement, 6. cutterhead, 7. installing hole, 8. stopper slot, 9. projection in figure.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Broken branch weeding knife as shown in Figure 1, there is cutterhead 6, cutterhead 6 edge is provided with five blades around the center of circle, blade comprises integrated installation portion 1 and operate portions 2,1/2 place of operate portions 2 is bent into L shape, the both sides of operate portions 2 are provided with blade 3, are provided with five reinforcements 5 between blade 3, and blade 3 width is 10mm; Cutterhead 6 center offers installing hole 7; Installing hole 7 offers eight stopper slots 8, adjacent two stopper slot 8 centre distances are 5mm; Stopper slot 8 bottom adhe has antiwear projection 9.
Installation portion 1 is arranged on cutterhead 6 by screw 4; Projection 9 is rubber projection.
Before work, cutterhead 6 is arranged in the rotating shaft of weeder by installing hole 7, and stopper slot 8 plays the role of positioning; During work, blade rotates around the axis, and blade 3 builds branches and leaves under high-speed rotation, and the projection 9 bottom stopper slot 8 forms certain space between rotating shaft and stopper slot 8, slows down the wearing and tearing of rotating shaft to stopper slot 8.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
