Abstract

The invention discloses a chopping knife of a thresher, and relates to the technical field of agricultural tools processing. The chopping knife comprises a frame, an elongated lateral plate laterally arranged on the upper portion of one side of the frame, a plurality of cutters vertically installed on the lateral plate side by side, and the edges of the cutters face the inner sides of the frame. Compared with the prior art, the chopping knife solves the problem of poor threshing effect of a conventional thresher, unthoroughly threshing and wasting grains.

Description

Threshing machine stem cutting knife
Technical field
The present invention relates to agricultural equipment processing technique field, especially a kind of knife assembly grain and part footpath leaf cut from paddy rice bar on threshing machine.
Background technology
Existing threshing machine generally comprises frame, be arranged on the screen cloth of frame, above screen cloth, be provided with the grain threshing roller with ratchet in frame, adopt roll-type threshing, by under harvesting paddy rice, one end kernelly is with to be placed on grain threshing roller, grain threshing roller rotates, and the grain on paddy rice is hit down by the ratchet on grain threshing roller, rotates this paddy rice, all beaten by the ratchet of grain threshing roller to whole paddy rice, completed threshing course.But the footpath leaf belt grain one of part paddy rice leading portion can coexist by the ratchet of grain threshing roller grain threshing roller tangential force effect under peel and fly out, the grain after threshing is also much connected on footpath, and Threshing is poor, and threshing is thorough, waste grain.Therefore, need to design a kind of knife assembly, be arranged on the top of the side of grain threshing roller, by the paddy rice footpath chopping flown out, form grain, broken footpath and broken leaf, grain is separated from paddy rice more up hill and dale.
Summary of the invention
Problem to be solved by this invention is to provide a kind of threshing machine stem cutting knife, poor to solve existing threshing machine Threshing, and threshing is not thorough, the problem of waste grain.
In order to solve the problem, technical scheme of the present invention is: this threshing machine stem cutting knife includes frame, it is characterized in that: the side upper lateral of described frame is provided with the transverse slat of a block length shape, described transverse slat is erect side by side and is provided with polylith cutting knife, the blade of described cutting knife is inside described frame.
In technique scheme, more specifically scheme can be: the blade of described cutting knife comprises knife plate portion and is arranged at multiple bending cutting edge portion upwards in described knife plate portion, the centre of vertical spread configuration on front side of described knife plate portion, described cutting edge portion.
Further: described knife plate portion and described cutting edge portion one-body molded.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
This threshing machine stem cutting knife adopts and on the transverse slat of frame, arranges polylith blade to the cutting knife inside frame, in paddy rice on grain threshing roller during threshing, the blade place that the footpath of the band grain flown out is splashed to cutting knife is shredded by cutting knife, form grain, broken footpath and broken leaf, grain is separated from paddy rice more up hill and dale; Due to the tangential effect of grain threshing roller, the paddy rice of grain of ining succession breaks the splashing direction of bar towards the upper front of cutting knife, the design of special blade, the paddy rice of coming from splashed upward can be broken bar chopping by bending cutting edge portion upwards very tartly, and grain also breaks bar from paddy rice thereupon and cuts together with the broken bar of broken leaf.
Accompanying drawing explanation
Fig. 1 is the front view of the embodiment of the present invention;
Fig. 2 is the left view of the embodiment of the present invention;
Fig. 3 is the front view of the cutting knife of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
This threshing machine stem cutting knife as shown in Figure 1 to Figure 3, it includes frame 1, frame 1 comprises many cross bars and vertical pole and montant and forms, the side upper lateral of frame 1 is provided with the transverse slat 2 of a block length shape, transverse slat 2 is erect side by side polylith cutting knife 3 is installed, here polylith cutting knife 3 is inlaid on transverse slat 2 by multiple vertical cores that transverse slat is opened, for convenience detach; The blade of cutting knife 3 is inside frame 1, and in paddy rice on grain threshing roller during threshing, the blade place that the footpath of the band grain flown out is splashed to cutting knife 1 is shredded by cutting knife, forms grain, broken footpath and broken leaf, is separated more up hill and dale by grain from paddy rice.The blade of cutting knife 3 comprises knife plate portion 3-1 and is arranged at multiple bending cutting edge portion 3-2 upwards on knife plate portion 3-1, and the centre of 3-2 vertical spread configuration in cutting edge portion on front side of knife plate portion 3-1, knife plate portion 3-1 and cutting edge portion 3-2 is one-body molded.Due to the tangential effect of grain threshing roller, the paddy rice of grain of ining succession breaks the splashing direction of bar towards the upper front of cutting knife 3, the design of special blade, the paddy rice of coming from splashed upward can be broken bar chopping by bending cutting edge portion 3-2 upwards very tartly, and grain also breaks bar from paddy rice thereupon and cuts together with the broken bar of broken leaf.

Claims (3)
