Abstract
The invention provides a prepositioned cutting device of a standing grain cutting machine. The prepositioned cutting device of the standing grain cutting machine is characterized in that a stationary knife blade of the prepositioned cutting device of the standing grain cutting machine is riveted on a stationary knife beam; a movable knife blade is riveted on a movable knife rest; the movable knife rest is in a reversed channel steel shape; the four corners of the lower side of the movable knife blade are positioned by bearings; the bearings are positioned at the closest edge and bearing brackets are mounted on the stationary knife beam; the central line on the upper side of the movable knife rest is pressed by the bearings; the bearing brackets are mounted on the stationary knife beam. When the movable knife rest does reciprocating motion, the friction resistance is small and the power consumption is less; the prepositioned cutting device is not easy to abrade, is durable and can work reliably.
Description
Art
The present invention relates to a kind of cutter of corn mowing machine, belong to agricultural technology field.
Background technology
The cutter of current known corn mowing machine is reciprocating cutterbar, its structure is primarily of moving knife part, stationary knife part, pressuring blade device part composition, moving knife part be by knife section riveted on knife bar, stationary knife part is that pressuring blade device part is made up of pressuring blade device, friction plate, pad etc. by ledger-plate (or guard) riveted on stationary knife beam.Pressuring blade device is arranged on stationary knife beam, presses, protects moving knife bar, by adjustment friction plate, pad, controls the fit clearance between knife section and ledger-plate, makes moving knife bar reliable Wang reciprocating cutter in pressuring blade device guide groove.The shortcoming of this cutter is: owing to will ensure that cutter knife section and ledger-plate in Wang reciprocating cutter are fitted, can not because of excesssive gap or too small and cause in operation cutter shake or cutter clamping stagnation, so moving knife bar Wang reciprocating cutter in the guide groove of pressuring blade device is hard friction very close to each other, this just as wheel with brake travel, frictional resistance is very large, power consumption is large, and knife bar easily weares and teares again, causes and often will adjust pressuring blade device.
Summary of the invention
In order to overcome the existing cutter deficiency that frictional resistance is large in Wang reciprocating cutter, power consumption is large, easy to wear, the invention provides the preposition cutter sweep of a kind of corn harvester, this cutter is without pressuring blade device and friction plate, be made up of moving knife part, stationary knife part, location bearing part, moving knife part by knife section riveted on movable knife rack, stationary knife part by ledger-plate (or guard) riveted on stationary knife beam, movable knife rack is for falling channel steel type, corner is located by bearing, is supported below, and the support of bearing is arranged on stationary knife beam; Above movable knife rack, midline is pushed down by bearing, and the support of bearing is also arranged on stationary knife beam; Such movable knife rack in reciprocating motion light and handy flexibly, working resistance is little, power consumption is few, not easy to wear.The preposition cutter sweep of corn harvester solves the technical scheme that its technical problem adopts: cutter is made up of moving knife part, stationary knife part, location bearing part; Moving knife part by knife section riveted on movable knife rack; Stationary knife part by ledger-plate (or guard) riveted on stationary knife beam; Movable knife rack is down channel steel type, and this kind of shape improves the intensity of movable knife rack; Below movable knife rack, bearing location, corner place, supporting, limit movable knife rack and move forward and backward, and ensure that movable knife rack balances in Wang reciprocating cutter, stablize, the support of bearing is arranged on stationary knife beam; Midline bearing on movable knife rack is pushed down, and limits movable knife rack and vibrates up and down, and ensure the fit clearance in knife section, ledger-plate work, the support of bearing is also arranged on stationary knife beam.
The beneficial effect of the preposition cutter sweep of corn harvester is: the reciprocating middle frictional resistance of movable knife rack is little, and power consumption is few, not easy to wear, durable in use, reliable operation.
Accompanying drawing explanation
Fig. 1 is the left apparent structure figure of the preposition cutter sweep of corn harvester.Fig. 2 is the stationary knife part of cutter, location bearing partial top structural map and left apparent structure figure.Fig. 3 is moving knife top partial view diagram and the left view of cutter.
In figure: 1, ledger-plate; 2, stationary knife beam; 3, bearing; 4, the support of bearing; 5, the support of bearing; 6, bearing; 7, the support of bearing; 8, bearing; 9, movable knife rack; 10, knife section; 11, bearing; 12, the support of bearing; 13, bearing; 14, the support of bearing; 15 supports of bearing; 16, bearing.
Embodiment
In Fig. 1, Fig. 2, ledger-plate (1) riveted of the preposition cutter sweep of corn harvester is on stationary knife beam (2), knife section (10) riveted is on movable knife rack (9), movable knife rack (9) is for falling channel steel type, below movable knife rack (9), corner place locates with bearing (3) (6) (13) (16), bearing fixes on most welt place, such effect is best, and the support of bearing (4) (5) (14) (15) are arranged on stationary knife beam (2); Midline on movable knife rack (9), pushes down with bearing (8) (11), and the support of bearing (7) (12) are arranged on stationary knife beam (2).
Claims (1)
1. the preposition cutter sweep of corn harvester, it is characterized in that: the ledger-plate riveted of the preposition cutter sweep of corn harvester is on stationary knife beam, knife section riveted is on movable knife rack, movable knife rack is for falling channel steel type, below movable knife rack, corner place bearing is located, bearing fixes on most welt place, the support of bearing) be arranged on stationary knife beam; Midline on movable knife rack, pushes down with bearing, and the support of bearing is arranged on stationary knife beam.
