Abstract
The utility model discloses a big stem stalk crop spiral cutting knife header belongs to the agricultural machine field. Big stem stalk crop spiral cutting knife header, constitute by stationary knife, header, spiral cutting knife and helical drum etc.. When helical drum was transfered to the power of harvester and make it rotate, the spiral cutting knife also rotated thereupon, and spiral cutting knife and stationary knife cut off the crop straw between it, and the stem of plant stalk after cutting off carries the one end (harvester) of header to get into the stage of threshing along with helical drum's effect. This spiral cutting knife header cutting edge length is long, and the cutting edge is strong to the sliding cutting effect of crop straw, the difficult jam, and the machines vibration is little, can reduce consumption of power and improve the speed and the quality of cutting.
Description
Technical field
The utility model relates to a kind of large stem stalk crop spiral cutter header, belongs to agricultural mechanical field.
Background technology
Grain header main working parts comprises cropping knife, sheller unit and separation cleaning device.The primary link that harvesting link completes as grain header, the performance of cutter device has larger impact to harvesting quality.Existing cutter device is based on triangle or trapezoidal blade, when especially gathering in large stem stalk crop (as corn, rape, sugarcane and soybean), the defect of these technical schemes is, during knife section motion, need provide larger reciprocating thrust force and faster speed could cut off stem stalk, large to the loss of transmission mechanism and knife section.Problem that during in order to mainly solve large stem stalk crop harvesting, cutting is difficult, the novel large stem stalk crop spiral cutter header of specialized designs.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of large stem stalk crop spiral cutter header, can fly-cutting stem stalk, all has larger help to the stability improving harvesting speed, cut quality and header.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of large stem stalk crop spiral cutter header, is made up of stationary knife, header, spiral cutter and helix drum etc.When the power of grain header is passed to helix drum and makes it rotate, spiral cutter also rotates thereupon, completes cutting process with stationary knife.
Described spiral cutter, blade is line style helically, and its edge length is longer than common cutting knife.Described spiral cutter is arranged on helix drum.The stationary knife coordinated with spiral cutter, both sides are cutting edge, and described stationary knife is arranged in the ceding of Taiwan.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
Large stem stalk crop spiral cutter header of the present utility model, owing to utilizing spiral cutter, its edge length is longer than common cutting knife, and thus cutting speed is fast;
Large stem stalk crop spiral cutter header of the present utility model, due to the blade helically line of spiral cutter, the cut surface of crop straw helically tangent plane when thus working, blade is strengthened the Sliding cutting action of crop straw, and thus laborsaving during cutting, cut quality is good;
Large stem stalk crop spiral cutter header of the present utility model, because crop straw to be transported to one end of header with the effect of helix drum, thus header is not easy blocking, can solve that large stem stalk crop straw is difficult to be cut, susceptible to plugging problem;
Large stem stalk crop spiral cutter header of the present utility model, helix drum is rotary motion, the vibrative problem of reciprocal inertia when it overcomes reciprocal skive falchion movement, thus its vibration of header is little, noise is little, can improve cutting speed, improves the reliability of header simultaneously.

Fig. 1 is large stem stalk crop spiral cutter header schematic diagram of the present utility model;
Fig. 2 is the large spiral cutter of stem stalk crop spiral cutter header of the present utility model and the position view of stationary knife;
Fig. 3 is the crop straw cutting schematic diagram of large stem stalk crop spiral cutter header of the present utility model.
Mark in figure: 1-stationary knife, 2-header, 3-spiral cutter, 4-helix drum.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that concrete case study on implementation described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-3, large stem stalk crop spiral cutter header of the present utility model, is made up of stationary knife, header, spiral cutter and helix drum.When the power of grain header is passed to helix drum and makes it rotate, spiral cutter also rotates thereupon, completes cutting process with stationary knife.
Described spiral cutter, blade is line style helically, and its edge length is longer than common cutting knife.Described spiral cutter 3 is arranged on helix drum 4.The stationary knife 1 coordinated with spiral cutter, both sides are cutting edge, and described stationary knife is arranged in the ceding of Taiwan 2.
The operation principle of described large stem stalk crop spiral cutter header is: when the power of grain header is passed to helix drum 4 and makes it rotate, spiral cutter 3 also rotates thereupon, crop straw 5 between it is cut off (as shown in Figure 3) by spiral cutter and stationary knife, and one end (grain header) that the crop straw 5 after cut-out is transported to header with the effect of helix drum enters the threshing stage.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
