Description

Stalk cutter

The utility model relate to a kind of be used for the chopping of straws such as wheat, paddy rice and with the matching used technology of combine, be a kind of Straw cutting machine.

In the combine in the past, straw does not just directly drop in the field by chopping, and straw is longer, influences the operation of turning over; People adopt the way of burning straw, usually so that better turn over operation when ploughing; This original method causes serious air pollution on the one hand, and because sometimes, flare is difficult to control, causes fire easily; On the other hand, it is inner organic to have destroyed straw, can not effectively utilize straw base manure.Also be furnished with cutter mill on some grain header now, but that its moving knife, stationary knife are joined straight installation is unreasonable, will influences its cutting effect and service life.

The utility model be provide at above-mentioned situation a kind of can be matching used with combine, can effectively shred the Straw cutting machine of straw.

Straw cutting machine of the present utility model can with the existing supporting use of various grain headers, be contained in grain header straw shaker below, straw drops in the cutter mill after discharging from straw shaker, throwing through shredding after looses goes back the field.This Straw cutting machine has transmission device and frame, and further includes the chopping rotor that driven by transmission device, is installed in epitrochanterian moving knife of chopping and rack-mounted stationary knife assembly; The chopping rotor is formed by two semiaxis and sleeve seam, is welded with cutterhead on the sleeve, and knife section is housed on the cutterhead, and the stationary knife assembly is to be made of stationary knife beam and the stationary knife that is contained on the stationary knife beam.

Bearing place at above-mentioned transmission device is equipped with overload alarm, is a kind of device of stopping up of preventing.

Above-mentioned moving knife for fixed directly through toothed from the sharpening moving knife.

The utlity model has simple in structure, characteristics such as shredding efficiency height, and since adopt fixed directly through toothed from the sharpening moving knife, has the light weight saving energy, advantages such as cutting quality is good, be also field of a kind of realization stem stalk, the desirable outfitting tool of no-tillage cover-seeding, can with the existing supporting use of various grain headers.

Describe technology contents of the present utility model and architectural feature in detail below in conjunction with accompanying drawing:

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1;

Fig. 3 is the B-B sectional structure schematic diagram of Fig. 1.

Referring to Fig. 1, Fig. 2 and Fig. 3, Straw cutting machine of the present utility model has transmission device and frame; Transmission device has generally comprised master and slave belt pulley and driving belt, according to actual conditions, also can between master and slave belt pulley, breast wheel be installed, regulating wheel etc., can pass to power (on grain header) on the cutter mill by transmission device, only reflect driven pulley 1 among the figure.This Straw cutting machine also further includes the chopping rotor 2 that is driven by transmission device, be installed in epitrochanterian moving knife 3 of chopping and rack-mounted stationary knife assembly 4, chopping rotor 2 is formed by two semiaxis 21 and sleeve 22 seam, have bearing 23 on the two-semiaxle 21 and be installed on the cutter mill biside plate 5, wherein be installed with driven pulley 1 on the semiaxis by bearing block 24.Evenly be welded with cutterhead 6 on the sleeve 22, moving knife is fixedly mounted on the cutterhead 6 by bolt etc., also can moving knife be welded on the cutterhead 6, generally speaking, is equipped with six knife sections on each cutterhead 6, also can decide according to actual conditions.Stationary knife assembly 4 is to be made of stationary knife beam 41 that is installed in 5 of biside plates and the stationary knife 42 that is contained on the stationary knife beam, stationary knife 42 is perpendicular with sleeve, stationary knife is between the sleeve cutterhead and at a distance of the sleeve certain distance, when moving knife rotates, moving knife is approximately 1/3～2/5 of stationary knife with the folded mutually part of stationary knife (two cuttves are nonoverlapping from the space, the said overlapping part that plays effective chopping effect when the chopping straw that is meant) here; Below stationary knife assembly 4, be equipped with web 7, and be extended down to sleeve below (shown in Figure 3); On the opposite of stationary knife assembly 4 (being the left side of sleeve, shown in Figure 3), between two plates, be equipped with plate washer 8, plate washer 8 belows are equipped with deflector 9, have breach at deflector 9 and 7 of webs.The utility model links to each other with grain header by its frame etc. in use, and straw enters in the cutter mill from top, utilizes deflector that broken cane or quarter butt after chopping are thrown to the field by indentation, there after the chopping, to realize goal of the invention of the present utility model.

Above-mentioned moving knife 3 is toothed from the sharpening knife section for deciding diameter, shown in Figure 3, the both sides of knife section have autogenous grinding cutting edge 31, has cutter tooth 32 on its end cutting edge, this blade can cooperate with stationary knife shred straw effectively after, its chopping straw length is about 10cm, the straw after its chopping is shed afield equably through cutter mill, do not influence the second stubble crop growth, adaptability is strong.

Above-mentioned bearing place is equipped with overload alarm, and its technology adopts existing electronic technology, does not explain at this, is a kind of warning device of stopping up of preventing, alarm can be reported to the police in advance when overload occurring.

Have plug 10 at above-mentioned sleeve two ends, two-semiaxle is welded to connect with plug 10 respectively.

Above-mentioned said frame is used for fixing or installs some auxiliary components of cutter mill, and matches with grain header by frame and to be connected.
