Abstract

The utility model discloses a rice-wheat harvester cutter, composed of a bar fixed blade (3), a plurality of bar movable blades (6), a movable blade arm (8), a blade shaft (7), and movable shaft connectors (4, 5). The utility model is characterized in that the fixed blade (3) is fixed on the upper portion of a divider (1) at the front of a cutting table (2) of rice-wheat harvester, one end of the movable blade arm (8) is fixed with the blade shaft, while another end is fixed with the movable blades, one end of the blade shaft is provided with elements (4, 5) connected with a power shaft. The utility model has simple structure, simple production, long service life, low energy consumption, high efficiency and low accident rate.

Description

Harvester for both rice and wheat cuts the fringe cutter

Technical field

The utility model relates to agricultural machinery harvesting machinery technical field, especially a kind of harvester cutter.

Background technology

The grain header kind is more at present, the large-scale combine of existing structure complexity, small-sized cart type harvesting threshing integral machine and the hand grain header of manpower are also arranged, the cutter that above-mentioned grain header uses mainly contains sawtooth blade proper alignment and constitutes upper and lower layer cutter with rivet on steel bar, cut by reciprocating motion cut rice and wheat, it is another kind of that also having a kind of is shearing tool for the rotating disc cutter cuts by rotation, above-mentioned cutter all exists consumed power big, efficient is low, the defective that cutter very easily damages.

The utility model content

The purpose of this utility model is to overcome the prior art deficiency, provide a kind of consumed power little, the efficient height, non-damageable harvester for both rice and wheat cuts the fringe cutter, the purpose of this utility model realizes by following technical proposals: by a strip ledger-plate and several strip knife sections, the knife section support arm, blade shaft reaches with the line shaft connecting elements to be formed, ledger-plate is fixedly connected on the nearside divider top in harvester for both rice and wheat ceding of Taiwan the place ahead, knife section support arm one end is fixedlyed connected with blade shaft, the blade support arm other end is fixedlyed connected with knife section, and blade shaft one end is provided with the member that links to each other with line shaft.

It is good that the knife section number is 2-10.

The knife section support arm can be affixed with the rotating shaft middle part, and the knife section support arm also can be fixed in the rotating shaft both sides, and two corresponding support arms are fixedlyed connected with a knife section end respectively.

Several knife section spacings equate.

During use, earlier ledger-plate is fixed in the nearside divider top in ceding of Taiwan the place ahead, bearing block socket on blade shaft and the ceding of Taiwan two side stands, the connecting elements sprocket wheel of blade shaft or belt pulley link to each other with line shaft by chain or belt, the nearest operating distance of ledger-plate and knife section is good with 0.1-0.5cm, drive the blade shaft rotation by line shaft during harvesting, knife section rotates to the front lower place, it can play the effect of the dialing-grain unit of combine when just beginning, and plays dissection when it is close with ledger-plate, the rice of cutting off, the wheat head is under moving knife drives, the more convenient threshing bin that enters thereafter carries out threshing, because it only is the cutting rice, wheat head neck, thereby institute's wasted work rate is little, the efficient height, also lay laborsaving basis efficiently for the threshing of back, ledger-plate and knife section all are list structures in addition, and intensity is big, and be not fragile.

From above-mentioned situation as can be known, the purpose of this utility model can realize that compared with prior art, it has following advantage: the one, and simple in structure, easy to make.The 2nd, energy consumption is little, the efficient height.The 3rd, durable in use, not fragile.The 4th, be difficult for being twined by plant stalk, fault rate is low.

Embodiment

Embodiment 1, and as shown in Figure 1, the utility model reaches the member that is connected with line shaft by a strip ledger-plate 3 with several strip knife sections 6, knife section support arm 8, blade shaft 7 and constitutes.Ledger-plate is fixedly connected on nearside divider 1 top in the harvester for both rice and wheat ceding of Taiwan 2 the place aheads, fixed, the length of knife section is decided as required, but it should be no more than ceding of Taiwan upper slitter bobbin two stands 9 spacings, knife section support arm 8 one ends are fixedlyed connected with blade shaft 7, support arm 8 one ends are fixedlyed connected with knife section 6, the knife section support arm other end is fixedlyed connected with blade shaft, knife section can be only to fixedly connected with a support arm in the middle part, also can be that corresponding with two the respectively knife section arm end in two ends is affixed, if knife section middle part is with a knife section support arm when affixed, then the knife section support arm is fixedlyed connected with the blade shaft middle part, if corresponding with two respectively knife section support arm one end in knife section two ends is when affixed, then the Dui Ying two knife section support arm other ends are fixedlyed connected with the blade shaft both sides respectively, and present embodiment is selected the latter for use.If knife section becomes symmetric arrays, two knife section support arms of correspondence can be designed to an integral body, its middle part is affixed with blade shaft.The length of blade shaft is decided as required, generally when rotating to minimum point, knife section and ledger-plate spacing are that 0.1-0.5mm is good, the number of knife section is decided as required, it can be two, four, six, eight, also three, five, seven, nine, the spacing of each knife section should equate.Present embodiment is selected four knife sections for use, and corresponding two blade support arms design is in aggregates, and blade shaft one end is provided with

driving member

4,5, and said driving member can be belt pulley 4 or gear, so that link to each other with line shaft by chain or belt 5.

Claims

1. a harvester for both rice and wheat cuts the fringe cutter, form by a strip ledger-plate (3) and several strip knife sections (6), knife section support arm (8), blade shaft (7) and with line shaft connecting elements (4,5), it is characterized in that: ledger-plate (3) is fixed in nearside divider (1) top in the harvester for both rice and wheat ceding of Taiwan (2) the place ahead, knife section support arm (8) one ends are fixedlyed connected with blade shaft, the blade support arm other end is fixedlyed connected with knife section, and blade shaft one end is provided with the member (4,5) that links to each other with line shaft.
