Abstract
The utility model relates to the combined harvester technology, in particular to a cutting blade for a combined harvester. The technical scheme is that the cutting blade for the combined harvester comprises an installation part and a working part, a plurality of blade teeth are respectively arranged on the two sides of the working part, and the plurality of blade teeth are mutually parallel and extend toward the middle of the working part along the edges of the working part. Due to the fact that one ends of the blade teeth, close to the middle of the working part, incline to the installation part, the blade teeth is in the shape of inclination. The blade has good smashing effect.
Description
Technical field
The utility model relates to the combining machine technology, particularly a kind of cutting blade of combine.
Background technology
In the prior art, the cutting blade of combine straw reducing mechanism as shown in Figure 1, this cutting blade comprises installation portion 1 and operate portions 2, the both sides of described operate portions 2 are respectively equipped with some cutters tooth 21 that extend to described operate portions middle part along described operate portions edge that parallel, this cutter tooth 21 is flat tooth, and namely cutter tooth 21 is vertical with the axis of blade; Or as shown in Figure 2, cutter tooth 21 tends to described installation portion 1 from an end that is positioned at described operate portions 2 edges and forms skewed cutter tooth; Yet the crushing effect of these two kinds of cutting blades is relatively poor.
The utility model content
The purpose of this utility model provides a kind of cutting blade of combine, and this kind blade has crushing effect preferably.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of cutting blade of combine, comprise installation portion and operate portions, the both sides of described operate portions are respectively equipped with some cutters tooth that extend to described operate portions middle part along described operate portions edge that parallel, and described cutter tooth tends to described installation portion and makes cutter tooth become skewed from the end near described operate portions middle part.
As of the present utility model preferred, described cutter tooth and described operate portions are provided with the formed inclination angle beta of side of described cutter tooth less than 90 degree.
As of the present utility model preferred, the formed inclination angle beta of side that described cutter tooth and described operate portions are provided with described cutter tooth is the 80-85 degree.
As of the present utility model preferred, the both sides of described operate portions extremely are the gathering shape away from an end of described installation portion along an end of close described installation portion.
In sum, the utlity model has following beneficial effect: unique texture of the present utility model, the particularly setting of cutter tooth incline direction, make when crushed straw, cutter tooth can be cut along the machine direction of straw, thereby reach good crushing effect.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as all are subjected to the protection of Patent Law in claim scope of the present utility model.
Embodiment: shown in Fig. 3-5, a kind of cutting blade of combine comprises installation portion 1 and operate portions 2 that one connects; The both sides of operate portions 2 extremely are the gathering shape away from an end of described installation portion 1 along an end of close described installation portion 1.
The both sides of operate portions 2 are respectively equipped with some parallel cutters tooth 21 that extend to described operate portions 2 middle parts along described operate portions 2 edges, and cutter tooth 21 tends to described installation portion 1 and makes 21 one-tenth of cutters tooth skewed from the end near described operate portions 2 middle parts.
Generally, cutter tooth 21 is spent less than 90 with the formed inclination angle beta of side that operate portions 2 is provided with cutter tooth 21, is preferably the 80-85 degree, and this angle beta of present embodiment is 85 degree.
