Description
Technical field
The utility model relates to a kind of horizontal horizontal maize harvesting machine ceding of Taiwan, belongs to agricultural machinery technological field.
Background technology
The ceding of Taiwan is as the vitals of maize harvesting machine, and taper nearside divider commonly used is realized the branch standing grain operation of corn stem; In a minute standing grain process, can accomplish propping up of falling corn simultaneously, and it gets between the snapping bar by the rice-pulling chain guiding.Because this mode all is passive work in a minute standing grain, the process of propping up; And the stem stalk there is propelling movement power forward in minute standing grain process; Leak and pluck problem so fruit ear that the stem stalk pushed over and cause often occurs, particularly serious to this problem of falling corn, caused the harvest corn process to pluck the obvious increase of fringe loss; The standing grain carrier chain of dialling is arranged at the nearside divider bottom in addition, and this structure so the problem of chain fracture often occurs, has had a strong impact on the functional reliability of facility owing to receive the restriction of chain drive defective; Two snapping bars are driven by pair of engaged gears, and active transport is haled the stem stalk downwards, backward, accomplish the excision of fruit ear.In order to improve the adaptability of snapping bar to the different cultivars corn; Its snapping bar gap requires adjustable, but receives the restriction of gears engaged, causes plucking very difficulty of fringe gap adjustment; Even adjusting also can only be the forced adjustment that makes the snapping bar distortion reluctantly; So not only caused the increase of bearing, travelling gear load, and accelerated the wearing and tearing of gear teeth face, shortened the life-span of bearing and gear; Cause simultaneously vibrating, the aggravation of noise; At last, because to pluck roller parallel with the direction of machine travel, though help corn stem importing snapping bar gap, the obvious increase that has also brought the unit longitudinal length has influenced the job area and the road trafficability characteristic of facility fields.
The utility model content
The purpose of the utility model provides a kind ofly can overcome above-mentioned defective, improve maize harvesting machine divides standing grain, seedling-erecting performance, minimizing to push over stem stalk and fruit ear to leak and pluck loss, dwindle the horizontal horizontal maize harvesting machine ceding of Taiwan of complete machine longitudinal length, reliable working performance.Its technical scheme is:
Comprise frame and rack-mounted nearside divider, ear-picking unit and ear forwarder, along the direction of machine travel, nearside divider is positioned at the front end of frame; Ear-picking unit near nearside divider, be positioned at the back upper place of nearside divider; It is characterized in that: nearside divider comprises many groups, and each group includes two Reducing screw screw feeders, and the spiral screw feeder is fixed on the frame through the clutch shaft bearing seat respectively; Become 15～30 ° of angles with horizontal plane; And the orthographic projection of two spiral screw feeders is " eight " font in each group, and blades height becomes greatly to end from the head end of spiral screw feeder gradually, leaves the gap between the head end of two adjacent spiral screw feeders in the two adjacent groups nearside divider; Ear-picking unit comprises a long snapping bar and a plurality of short snapping bar; Wherein long snapping bar is installed on the frame through the bearing level; And axially vertical with the direction of machine travel, a termination Power Drive Unit of long snapping bar, the corresponding short snapping bar of each group nearside divider; The two ends of each short snapping bar are installed on the frame and a little more than long snapping bar through the second bearing block level of interior dress spherical self-aligning bearing respectively; The fringe gap of plucking that the head end of short snapping bar, terminal and long snapping bar constitute is respectively 10～15cm and 1～2cm, the gap that the fringe gap is slightly larger than every group of spiral screw feeder end of plucking of the head end of short snapping bar and long snapping bar formation, and be positioned at nearside divider the back upper place, and the terminal vertical range of spiral screw feeder be 10～30cm; Ear forwarder is positioned at the rear end of long snapping bar; And be lower than long snapping bar, help accepting the corn ear of taking, and accomplish the lateral transfer and the collection of fruit ear.
The described horizontal horizontal maize harvesting machine ceding of Taiwan, the head end spacing of each group spiral screw feeder is 60～80cm, terminal spacing 6～10cm.
Its operation principle is: during work, along with moving ahead of machine, be positioned at the sphere of action that the preceding corn stem of every group of nearside divider gets into the blade of spiral screw feeder successively.Along with the rotation of spiral screw feeder, at first falling corn stem stalk is propped up from root by two spiral screw feeder head ends in every group of nearside divider, under the effect of blade, force then it is pushed backward.Because the fringe gap is plucked less than what the head end of short snapping bar and long snapping bar constituted in the terminal gap of two spiral screw feeders in every group of nearside divider, thereby guarantee that blade can be with corn stem long and short two snapping bar gaps of importing smoothly.Get into the corn stem in long and short two snapping bar gaps; Under the protruding effect of long snapping bar rib; End to short snapping bar moves gradually, and is clamped to short snapping bar end gradually, moves downward, because the fruit ear diameter is much larger than the snapping bar gap by two snapping bars; So when downward frictional force during greater than the connection power of fruit ear fringe handle, fruit ear is just taken.That the fruit ear of taking drops under action of gravity is lower in the position, be positioned on the ear forwarder of long snapping bar rear end, by it fruit ear is carried backward.
The utility model compared with prior art has following advantage:
1, two spiral screw feeders in every group of nearside divider adopt front wide and rear narrow " eight " fonts to distribute, can satisfy the different spacings corn in gather and import.
2, the blades height of each spiral screw feeder becomes greatly to end from the head end of spiral screw feeder gradually, and wherein the front end blade helps being positioned at the sphere of action that its preceding corn stem gets into blade for a short time, and the rear end blade helps strengthening the propelling movement effect to corn stem greatly.
3, each spiral screw feeder becomes low early and high after distribution in vertical direction, can guarantee like this to prop up being positioned at the preceding falling corn of nearside divider, reduces the leakage of fruit ear and plucks and overwhelm.
4, long and short snapping bar lateral arrangement helps reducing the longitudinal size of machine, dwindles the turning radius of complete machine, improves the road trafficability characteristic of reaping machine.
5, long and short snapping bar structure independent distribution, wherein long snapping bar active transport, short snapping bar has only when corn gets into two snapping bar gaps, and just passive rotation under the cane function of friction has effectively been practiced thrift power consumption.
6, a plurality of short snapping bar structures are independent, saved meshing gear, and are not only easy to adjust, and reduced adjusting resistance and power consumption.
7, the two ends of each short snapping bar are installed on the frame through the second bearing block level of interior dress spherical self-aligning bearing respectively, can satisfy the adjusting requirement of plucking the fringe gap.
8, long snapping bar position is a little less than short snapping bar, and the fruit ear that helps taking drops to ear forwarder.
9, ear forwarder is positioned at the rear portion of long snapping bar, and the position is lower than long snapping bar, helps accomplishing lateral transfer and the collection of taking fruit ear.
