Description

A kind of rotary drum type cutter of micro combine

Affiliated technical field

The utility model relates to a kind of rotary drum type cutter of paddy rice harvesting machinery, particularly a kind of micro combine.

Background technology

In the prior art, the harvesting mode of miniature combine harvester has full feeding and partly feeds two kinds, and its cutter have disc type and reciprocating type cutter, mostly be installed in the preceding position down of sheller unit, and the edge of a knife in horizontal direction.For full feed type, adopt one cutter, in the summary upper part of standing grain pocket straw is cut off; For semi-feeding type, then adopt two cutter one on the other, straw is cut off into two sections respectively in the position under the summary of the summary upper part of standing grain pocket and spike of rice.The cutting of this dual mode, though can realize straw incorporation, the grass section that it cuts into is also long, but also is to scatter on the face of field messyly, does not insert in the earth.

The utility model content

At the deficiencies in the prior art, technical problem to be solved in the utility model provides a kind ofly can be slit into straw very short grass section, and the grass section can be pressed into the cutting tool of the micro combine in the earth.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: design a kind of rotary drum type cutter of micro combine, this machine comprises fixed blade 36 and knife section 35; Fixed blade 36 is the double-deck blade of hollow, is axially fixed on the cylindrical of cylinder 31, and the hollow part that knife section 35 is installed on fixed blade 36 constitutes cutter; The fulcrum 42 of cylinder 31 left ends is installed in the left shaft holder 39 that has left fixed support 37, and right-hand member fulcrum 25 is installed in the right bearing seat 18 that has right fixed support 16 after passing the sliding sleeve 23 of fixing knife section 35; Shifting fork device 32 is contained on the right fixed support 16, is connected with dome dish on the sliding sleeve 23.

The hollow of fixed blade 36 is triangle, and the cross section of knife section 35 is the triangle similar to the triangle hollow of fixed blade 36.

On the cylindrical of cylinder 31, axially be fixed with two to four groups of cutter of forming by fixed blade 36 and the knife section 35 that is installed on its hollow part symmetrically.

On the cylindrical of cylinder 31, axially be fixed with the pressure grass tooth bar 34 identical symmetrically with cutter quantity.

Between the cylindrical of the endoporus of sliding sleeve 23 and right-hand member fulcrum 25, sliding shaft sleeve 24 is housed.

Shift fork journal stirrup 30 in the shifting fork device 32 is contained in the both sides of the slotted eye on the right fixed support 16, by shift fork bearing pin 29 hinge dress shift forks 28; The prong of the upper end of shift fork 28, fork is gone into the dome dish on the sliding sleeve 23, and its right-hand member has bulb 13; The concave spherical surface head 12 of connecting rod 10 upper ends entangles bulb 13, is pushed down by the upper and

lower gland

15 and 14 of shift fork bulb, and its lower end is hinged with itself and eccentric rod 3 by pitman pin 5; The right part of power input shaft 44 passes dress eccentric wheel 6 behind the bearing block of right fixed support 16 lower ends, and the eccentric bushing 2 of eccentric rod 3 lower ends is contained on the eccentric wheel 6 by cam pin 1 hinge.

On the right side of right fixed support 16, protective cover 11 is housed.

The rotary drum type cutter of micro combine of the present utility model because at least two cutter have been installed, when cylinder rotates a circle, has promptly carried out cutting twice on cylinder, thereby the grass section that is cut into is shorter, is scattered in the field also relatively evenly; Simultaneously, the pressure grass tooth bar of same quantity has been installed also on the cylinder, when cylinder rotates, the grass section can be pressed in the earth, helped the grass section and rot, be converted into organic manure as early as possible.
