Abstract
A spiral picking roll of a corn harvester relates to an ear picking mechanism of the corn harvester, in particular to an improvement of the picking roll of the corn harvester. The picking roll comprises a front guide cone section (1), an ear picking section (2), a forced drawing section (3) and a back shaft (4). The circumference of a base roll of the ear picking section (2) is provided with a spiral guide body (5) and stem drawing teeth (6); the spiral guide body (5) is a constant-pitch screw the outer side surface of which takes an arc shape; the stem drawing teeth (6) are evenly distributed on internodes of the spiral guide body (5), and the height of the stem drawing teeth (6) is shorter than that of the spiral guide body (5). The picking roll has the advantages of strong adaptability, low loss rate of corn ears, low impurity content and low loss rate of corn kernels, and effectively improves the operating efficiency of the corn harvester.
Description
Technical field
The present invention relates to the maize harvesting machine corn snapping unit, particularly to the improvement of maize harvesting machine snapping bar.
Background technology
The maize harvesting machine corn snapping unit is the core component of whole corn harvesting machine, and it has farthest determined the quality of corn maturing stage mechanical harvest operation.At present, the fringe mode of mainly plucking that maize harvesting machine adopted has two kinds, and a kind of is to pluck the fringe plate and draw stem roller die formula, and another kind is the snapping bar pattern.Block fruit ear by plucking the fringe plate when plucking the fringe plate and drawing the operation of stem roller die formula,, exist power consumption big, be easy to cause corn stalk to fracture the shortcoming that percentage of impurity is high from fruit ear carpopodium portion by drawing the drop-down by force corn stalk of stem roller to realize plucking fringe; Realize plucking the fringe function by the helical grip extruding of plucking fringe base roller and be welded on the basic roller during operation of snapping bar pattern, have that power consumption is low, harvesting the early stage has the low advantage of percentage of impurity, but arrived the harvesting middle and advanced stage, the cane water content descends, the fruit ear maturation, seed is lax, and helical grip is easy to lax seed extruding is grabbed, and causes the seed percent of loss significantly to improve.Moreover, more than two kinds pluck the fringe pattern all can not the full phase operation of fine adaptation, in actual applications, all exist and easily break or extrusion damage fruit ear phenomenon, particularly sting a phenomenon, percentage of impurity and seed percent of loss are increased.
Summary of the invention
Technical problem to be solved by this invention is: provide that a kind of adaptability is strong, fruit ear percent of loss, percentage of impurity and the low screw type picking roll of maize harvesting machine of seed percent of loss.
Technical solution of the present invention is: it comprises preceding starting taper section, plucks fringe section, the section of haling and rear axle, the periphery of plucking fringe segment base roller is provided with the spiral-guide body and draws the stem tooth, the spiral-guide body is that outer surface is the uniform pitch conveyor screw of circular arc, draw the stem tooth to be distributed in the internode of spiral-guide body, draw the stem tooth height less than spiral-guide height degree.
Technique effect of the present invention is: it has, and adaptability is strong, fruit ear percent of loss, percentage of impurity and the low advantage of seed percent of loss, has effectively improved the operating efficiency of maize harvesting machine.
Description of drawings
Accompanying drawing is main TV structure figure of the present invention.
Embodiment
As shown in drawings, it comprises preceding starting taper section 1, plucks fringe section 2, the section of haling 3 and rear axle 4, the periphery of plucking fringe section 2 basic rollers is provided with spiral-guide body 5 and draws stem tooth 6, spiral-guide body 5 is that outer surface is the spring-like uniform pitch conveyor screw of circular arc, draw stem tooth 6 to be distributed in the internode (place, space of every circle) of spiral-guide body 5, draw stem tooth 6 height less than spiral-guide body 5 height.
The described angle that draws stem tooth 6 and pluck between fringe section 2 axis is 0-45 °.
Described draw stem tooth 6 by pluck fringe section 2 axis directions be arranged in parallel be 4 the row.
In the present embodiment, pluck fringe section 2 basic roller diameters and adopt 45-70mm; Spiral-guide body 5 employing diameters are that the round steel of 14-20mm is spirally wound on the periphery of plucking fringe section 2 basic rollers with 40-50mm pitch; Draw stem tooth 6 outer surfaces for and pluck the circular arc that fringe section 2 adapts, draw that stem tooth 6 is wide to be 8-10mm, height is 12-14mm.In the present embodiment, draw stem tooth 6 also can promptly only establish two row near preceding starting taper section 1 place in the first section of making, length is about 300mm.
When on maize harvesting machine, installing, install from anterior opened with certain angle between the pair roller, so that corn stalk passes through, the half pitch that staggers between the spiral-guide body 5 of two snapping bars, what make spiral-guide body 5 and another roller draws stem tooth 6 relative engagement.During operation, two snapping bars rotate in opposite directions, corn ear and straw are directed into by preceding starting taper section 1 and pluck fringe section 2 and carry out ear harvesting operation, straw is pulled down by the gap of drawing stem tooth 6 from pair roller, corn ear is taken with straw owing to the obstruct of spiral-guide body 5 to be separated, and special straw is pulled out by force by the section of haling 3.Because in plucking the fringe process, corn ear is intercepted by spiral-guide body 5 and does not contact with drawing stem tooth 6, thereby has avoided stinging a phenomenon.Moreover, corn ear when winning and the stress point that drawn of straw very near, near the root of corn ear, do not break the straw phenomenon so be not prone to.Therefore, its fruit ear percent of loss of reaping machine, percentage of impurity and the seed percent of loss of using the present embodiment snapping bar all reduce greatly, be better than at present employedly plucking the fringe plate and drawing the maize harvesting machine of stem roller die formula and snapping bar pattern, go for the harvest operation in territory and different cultivars corn variously.
Claims (3)
1. screw type picking roll of maize harvesting machine, starting taper section (1) before comprising, pluck fringe section (2), section of haling (3) and rear axle (4), it is characterized in that, the periphery of plucking the basic roller of fringe section (2) is provided with spiral-guide body (5) and draws stem tooth (6), spiral-guide body (5) is that outer surface is the uniform pitch conveyor screw of circular arc, draw stem tooth (6) to be distributed in the internode of spiral-guide body (5), draw stem tooth (6) height highly less than spiral-guide body (5), the half pitch that staggers between the spiral-guide body (5) of two snapping bars, the spiral-guide body (5) that makes a snapping bar and another snapping bar draw stem tooth (6) relative engagement.
