Abstract
The utility model discloses a sugarcane harvesting cutter. The sugarcane harvesting cutter comprises blades, a coupling disc and a cutter disc, wherein the coupling disc is provided with a shaft hole; the shaft hole is provided with a key slot; a concave plane is arranged in the middle of the cuter disc; the coupling disc is fixedly connected with the concave plane of the cuter disc by a first cutter disc bolt; the blade is arc-shaped; one ends of the blades are fixedly connected with the cutter disc by second cutter disc bolts; saw-tooth cutting edges are arranged at convex arc-shaped edges of the blades. When the harvesting cutter works, the harvesting cutter has cutting effects on thick and hard sugarcanes with different sizes and diameters; the three blades can work simultaneously so that the utilization rate of the cutter is greatly improved; meanwhile, the sugarcane harvesting cutter can also normally and reliably work under the condition that the two blades are abraded, and the harvesting efficiency is greatly improved.
Description
Technical field
The utility model relates to the technical field of grain header, particularly a kind of sugarcane harvesting cutter.
Background technology
In existing cane harvester, mainly take whole rod-type harvesting as main, cane harvester, in the process of walking, by the turning cylinder on power drive reaping apparatus, makes its cutterhead rotation, thereby sugarcane is cut off from root.For the reaping apparatus that sugarcane is cut off from root, mainly comprise hilted broadsword dish mode of operation and Double-cutter mode of operation, as China's invention of the Chinese utility model of publication number CN2439773Y and CN102687623A, all adopt sawtooth circular blade, thus, there is reconditioning difficulty in the type blade, harvesting efficiency is high and the technical problem of use cost rate deficiency.
Utility model content
Not enough for solving prior art, the purpose of this utility model has been to provide a kind of sugarcane harvesting cutter that reconditioning difficulty, harvesting efficiency are not high and utilization rate is not enough that solves.
In order to achieve the above object, the utility model provides a kind of sugarcane harvesting cutter, comprise blade, tie-plate and cutterhead, wherein, on described tie-plate, axis hole is set, on this axis hole, keyway is set, described cutterhead middle part arranges concave plane, and described tie-plate is fixedly connected with described cutterhead concave plane by the first cutterhead bolt; Described blade is curved, and described blade one end is fixedly connected with described cutterhead by the second cutterhead bolt, and described blade convex arc limit arranges sawtooth cutting edge.
Preferably, described blade arranges two or three on cutterhead, and is uniformly distributed.
Preferably, the shape of described tie-plate is rounded, and its area equates with the concave plane area of described cutterhead.
Preferably, between described blade and described cutterhead, alignment pin is set.
Compared with prior art, its beneficial effect is the utility model: the utility model proposes the cropping knife that has adopted the detachable arc-shaped broached-tooth design of three leaves.When this cropping knife work, the sugarcane of thick and stiff size diameter is played to the effect of cutting of cutting, and be that three blades can be worked simultaneously, greatly improved the utilization rate of cutter; Guaranteed in the situation that having two tool wears, work that also can normal reliable, has also improved harvesting efficiency greatly simultaneously.
Accompanying drawing explanation
Fig. 1 is vertical view of the present utility model.
Fig. 2 is the partial enlarged drawing at P place in Fig. 1.
Fig. 3 is A-A profile in Fig. 1.
In figure, 1. blade; 2. tie-plate; 3. cutterhead; 4. the first cutterhead bolt; 4 ＇ the second cutterhead bolt .5. alignment pins; 6. axis hole; 7. keyway; 8. sawtooth cutting edge.
Embodiment
For ease of the technological means of the utility model and operation are had to understanding and understanding further, below in conjunction with specific embodiment, be elaborated as follows.
As shown in Figure 1,2 and 3, a preferred embodiment of the present utility model provides a kind of sugarcane harvesting cutter, comprise blade 1, tie-plate 2 and cutterhead 3, wherein, on described tie-plate 2, axis hole 6 is set, on this axis hole 6, keyway 7 is set, described cutterhead 3 middle parts arrange concave plane, and described tie-plate 2 is fixedly connected with described cutterhead 3 concave planes by the first cutterhead bolt 4; Described blade 1 is curved, and described blade 1 one end is fixedly connected with described cutterhead 3 by the second cutterhead bolt 4 ＇, and described blade 3 convex arc limits arrange sawtooth cutting edge 8.
Wherein, described blade (1) arranges three on cutterhead (3), and is uniformly distributed.The shape of described tie-plate (2) is rounded, and its area equates with the concave plane area of described cutterhead (3).For the effect of strengthening being fixedly connected with, between described blade (1) and described cutterhead (3), alignment pin (5) is set.
When cropping knife is worked, three blades 1 can be worked simultaneously, have greatly improved the utilization rate of blade; Guaranteed that in the situation that having two tool wears work that also can normal reliable has also improved the harvesting efficiency of grain header greatly simultaneously.
Only preferred embodiment of the present utility model in sum.It should be pointed out that except above-described embodiment, described blade also can arrange more than two or three on cutterhead.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection scope of the present invention.
Claims (4)
1. a sugarcane harvesting cutter, comprise blade (1), tie-plate (2) and cutterhead (3), it is characterized in that: axis hole (6) is set on described tie-plate (2), keyway (7) is set on this axis hole (6), described cutterhead (3) middle part arranges concave plane, and described tie-plate (2) is fixedly connected with described cutterhead (3) concave plane by the first cutterhead bolt (4); Described blade (1) is curved, and described blade (1) one end is fixedly connected with described cutterhead (3) by the second cutterhead bolt (4 ＇), and described blade (1) convex arc limit arranges sawtooth cutting edge (8).
