Description

A kind of adjustable agricultural harvester cutter

Technical field

The utility model is related to agricultural machinery technology field more particularly to a kind of adjustable agricultural harvester cutters.

Background technology

In the big good time of good harvest, agricultural harvester is most wide as utility model scale, and most common farm machinery is climbed up The stage in autumn, peasant have increasing need for agricultural harvester to replace cumbersome hand harvest and beat rice link, in view of existing The routine of the agricultural harvester cutter of technology can not be gathered in preferably suitable for the farmland of any scene, the utility model design A kind of adjustable agricultural harvester cutter different needs are realized by adjustable three kinds of cutters, by cutting root cutter tune It is whole be most suitable for farming without root excision position carry out the root excisions of crops, while sharp except stem cutter are by farming The stem of object cuts off and collects it, and firewood is provided for peasant, finally by the grain on fringe by removing the progress of paddy cutter and stem Dry stripping realizes that the institute of the harvester cutter is functional, realizes the obstruction of the customer service varying environment in the cutting machine course of work, Crops under different situations are gathered in, three kinds of cutters can be arbitrarily taken in shaft, are avoided between cutter Interference can preferably allow people to be used alone any one cutter.

Utility model content

A kind of adjustable agricultural harvester cutter of the utility model design including housing and connects on the housing Shaft, be enclosed with harvesting cutter group on the outside of the shaft, it is characterised in that：Cavity volume, the receipts are provided on the inside of the shaft Cutter tool group includes rotating diameter maximum cutting root cutter, rotating diameter is minimum removing paddy cutter and being arranged on described cut Root cutter and it is described go between paddy cutter except stem cutter, the root cutter of cutting pass through elastic circlip and the shaft It cuts root cutter described in when connection, i.e. elastic circlip are opened and just falls into the cavity volume and be stopped, when needed, then open bullet Property clamp spring, throw away fixation with root cutter are cut described in centrifugal force, then work, it is described except stem cutter and the shaft Between connected by electric hinge.

As the preferred of the utility model, the blade cut root cutter and include the knife rest and hoe shape of strip arc, The root for cutting root cutter is provided with the cavity volume with the shaft junction, and the diameter of the cavity volume cuts root more than described The maximum gauge of the blade part of cutter.

It is described except stem cutter include at least two semi-circular reaping hooks as the preferred of the utility model, described two half Annular reaping hook is connected by hinge structure respectively at the shaft.

It is described that paddy cutter is gone to include multiple three square rings of closing surrounded by reinforcing bar, institute as the preferred of the utility model It states three square rings to be dislocatedly distributed in the base of tool, the cutter seating face is provided with the triangle appearance for accommodating three square rings of the closing Chamber.

As the preferred of the utility model, the harvesting cutter group is steel cutter, preferably W18Cr4V, The high-speed tool steels such as W6Mo5Cr4V2.

The utility model has the advantages that：

A kind of excessively adjustable three kinds of cutters of adjustable agricultural harvester cutter of the utility model design are realized different Need, by cut root cutter adjustment be most suitable for farming without root cut off position carry out crops root cut off, simultaneously The stem of crops is cut off and collects it by the sharp stem cutter that remove, and firewood is provided for peasant, finally by the grain on fringe By the way that paddy cutter is gone to carry out the stripping with stem, realize that the institute of the harvester cutter is functional, realize worked in cutting machine The obstruction of customer service varying environment in journey, gathers in the crops under different situations, can arbitrarily take in three kinds of cutters In shaft, the interference between cutter is avoided, people can preferably be allowed to be used alone any one cutter.

Below by drawings and examples, the technical solution of the utility model is described in further detail.

Description of the drawings

Fig. 1 is a kind of structure diagram of adjustable agricultural harvester cutter of the utility model.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

As shown in Figure 1, a kind of adjustable agricultural harvester cutter, including housing 1 and turn being connected on the housing 1 Axis 2,2 outside of shaft are enclosed with harvesting cutter group 3, it is characterised in that：2 inside of shaft is provided with cavity volume 21, described Harvesting cutter group 3 include rotating diameter it is maximum cut root cutter 31, rotating diameter it is minimum go paddy cutter 33 and setting It is described cut root cutter 31 and it is described go between paddy cutter 33 except stem cutter 32, the root cutter 31 of cutting pass through bullet Spring is buckled and the shaft 2 realizes contracting button connection, and described remove is connected between stem cutter 32 and the shaft 2 by electric hinge It connects.

In the present embodiment, the blade 312 cut root cutter 31 and include the knife rest 311 and hoe shape of strip arc, institute It states the root for cutting root cutter 31 and 2 junction of shaft is provided with the cavity volume 21, the diameter of the cavity volume 21 is more than institute The maximum gauge for the blade 312 for cutting root cutter 31 is stated, it is described except stem cutter 32 include at least two semi-circular sickles Knife, described two semi-circular reaping hooks are connected by hinge structure respectively at the shaft 2, described to remove paddy cutter 33 including multiple Three square ring 331 of closing surrounded by reinforcing bar, three square ring 331 are dislocatedly distributed on the base of tool 4,4 surface of the base of tool The triangle cavity volume 41 for accommodating three square rings 331 of the closing is provided with, the harvesting cutter group 3 is steel cutter, preferably The high-speed tool steels such as W18Cr4V, W6Mo5Cr4V2.

Embodiment described above is only that the preferred embodiment of the utility model is described, not new to this practicality The conception and scope of type is defined.Without departing from the design concept of the present utility model, ordinary people in the field is to this The all variations and modifications that the technical solution of utility model is made, should fall within the protection scope of the present utility model, this practicality Novel claimed technology contents have all been recorded in detail in the claims.
