Abstract
The utility model relates to a double-moving knife type cutter for cutting stalks and roots of plants, which belongs to the technical field of agricultural machinery design, particularly a design for a maize harvesting device. The utility model is characterized in that a pair of circular discs is eccentrically fixed on a rotary power shaft, a bearing is sheathed at the outer part of each circular disc, a push rod is connected with the upper part of an outer sleeve of each bearing, and the other end of each push rod is respectively connected with an upper cutter blade and a lower cutter blade; when the power shaft rotates, the two cutter blades do reciprocating movement. Compared with the existing rotary disc rotating sawtooth type cutter, the utility model has the advantage of simple structure, an eccentric swinging ring composed of the eccentric circular discs, the bearings and the push rods only need to be installed on the power shaft, so the reciprocating movement of wide width cutter blade and wide width harvesting work can be realized. The utility model has another advantage that smaller impact force is exerted at the stalks when the cutter works, so serious splashing phenomenon for the stalks can not occur. Stalk and root cut can be ideally realized by the utility model.
Description
Technical field
The utility model content belongs to the Agricultural Machinery Design technical field, particularly the reaping corn Design of device.
Background technology
On maize harvesting machine or other thicker plant harvesting machine, the cutter sweep that adopts mostly is rotary turnplate serration type cutter at present, and its operation principle is similar to the circle rotation electric saw of horizontal positioned.For plant multirow grain header, need the rotating disk saw cut assembly of a plurality of rotations, be with a plurality of rotary components of power drive more complicated structurally, cost is higher, fault rate is bigger.And this cutter is very big to the impulsive force of plant haulm, and broken at work stalk splash phenomena is serious.Therefore, design a kind of simple in structure, cost is low, well behaved stalk butt cutter is necessary.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, cost is low, performance is good stalk butt cutter.The method that is adopted is to be similar to the scissor or clippers formula structure that harvester for wheat is used, and fixes the another side blade movement but the harvester for wheat cutter is a blade.For corn stem and other thicker plant stem, the point of a knife of fixed blade may insert in the cane, and cane is produced the pushing phenomenon, cane is pushed over and causes Lou and cuts.The two sides blade that the utility model proposes all reciprocating " two moving-blade " cane cutter, as long as the movement velocity of blade enough just can be avoided the generation of this problem greatly, realize the cutting of cane root more satisfactoryly, and can avoid the excessive spatter phenomenon of stem stalk.
The basic structure of two moving-blade plant stem cutters as shown in drawings.Of the present utility model being characterised in that, rotary power axle (1) is gone up off-centre and is fixed with pair of discs (2), the outer bearing of suit (3) of each disk, outer the putting of each bearing connects a push rod (4), and the other end of each push rod connects bottom knife (5) respectively; Two blades move back and forth when line shaft rotates.
Compare with existing rotary turnplate serration type cutter, one of advantage of the present utility model is simple in structure, only need go up at line shaft (1) reciprocating motion that an off-centre pendulum ring as shown in Figure 2 just can be realized the wide cut blade is installed; This off-centre pendulum ring is pair of discs (2) and bearing (3) that is enclosed within the disk outside and push rod connecting ring (7) formation that is fixed together by off-centre.Another advantage is that cutter is less to the impulsive force that the stem stalk is applied at work, can not cause the excessive spatter phenomenon of stem stalk.The utility model can be realized the cutting of stem stalk root more satisfactoryly.
Description of drawings
Fig. 1 is two moving-blade plant stem bottom cutter structural representations, and Fig. 2 is several critical component figure (forming eccentric pendulum ring).Among the figure, 1 is line shaft, and 2 are the eccentric pair of discs that is fixed together, and 3 is bearing, and 4 is push rod, and 5 is blade, and 6 is the cutter box, and 7 is the push rod connecting ring, and 8 is the breach on the cutter box, and 9 is cutter box fixed mount.
Embodiment
Earlier pair of discs (2) off-centre is fixed together, then line shaft (1) is fixed on the centre of two disks, a bearing of suit (3) outside each disk (2), the interior cover of bearing and disk are fixing dead, bearing outside suit push rod connecting ring (7), the overcoat of connecting ring and bearing is fixing dead, one of push rod (4) connects push rod connecting ring (7), the other end connects bottom knife (5) respectively, blade is placed in the cutter box (6), blade can horizontally slip in the cutter box, and the cutter box is fixed on the fixed mount (9); Have breach (8) in the top panel both sides of cutter box (6) and a side of cutter, so that it is fixing with itself and push rod (4) to expose following blade.
Operation principle: when line shaft (1) rotates, drive the fixing disk (2) of two off-centre and carry out the off-centre rotation, the rotation of the off-centre of described disk can drive push rod connecting ring (7) and produce the reciprocating component in the left and right sides (connecting ring also seesaw component) certainly, push rod connecting ring (7) can make about push rod (4) and move back and forth, and drives about blade to move back and forth; And the direction of motion of two blades is always reverse, thereby two blades form shearing motion.
Claims (2)
1, two moving-blade plant stem bottom cutters, it is characterized in that, rotary power axle (1) is gone up off-centre and is fixed with pair of discs (2), each disk is set with a bearing (3) outward, outer the putting of each bearing connects a push rod (4), and the other end of each push rod connects bottom knife (5) respectively; Two blades move back and forth when line shaft rotates.
2, as claimed in claim 1 pair of moving-blade plant stem bottom cutter is characterized in that, blade (5) is that the edge of a rectangular metal plate is a zigzag fashion; Two described blades (5) are stacked together, and put into cutter box (6), and blade can slide in the cutter box.
