Problems solved by technology

The rib-type ear picking roller is generally divided into guide section, ear picking section and strong pulling section. The introduction section is a cone structure, which mainly plays the role of guiding the stalks into the gap between the ear picking rollers; the ear picking section is a single helical rib Cylinder, which plays the role of ear picking, the spiral direction of each pair of ear picking rollers is opposite, and they are arranged in a staggered manner; most of the ear picking rollers are petal-shaped or have a ribbed structure, and the disadvantage is that the working principle is forced extrusion ear picking, It is easy to cause the shedding and gnawing of grains (the proportion of gnawing ear damage can reach 25%, and it can reach 50% in severe cases), and it is easy to cause blockage when the feeding amount is large, which greatly affects the harvesting speed

Embodiment 1

[0030] Such as figure 1 , figure 2 and image 3 , This embodiment makes a detailed description of the structure and principle of a combined corn harvester picking roller of the present invention.

[0031] The invention provides a combined ear picking roller for a corn harvester, comprising an A-type roller and a B-type roller;

[0032] Described A-type roller comprises main roller upper spindle head 1, main fringe picking roller 2, main roller lower spindle head 3, sprocket wheel 4, auxiliary roller upper spindle head 5, main stem pulling roller 6 and auxiliary roller lower spindle head 7; The main roller upper spindle head 1 is inserted into the upper cavity of the main ear picking roller 2 and then welded together, and the main roller lower spindle head 3 is inserted into the lower cavity of the main ear picking roller 2. Welded together, the lower spindle head 3 of the main roller is a hollow thread structure, the upper spindle head 5 of the auxiliary roller is inserted...

Embodiment 2

[0036] Such as Figure 4 , Figure 5 and Figure 6 As shown, this embodiment is an embodiment further improved on the basis of Embodiment 1, and at the same time, a further detailed description of the present invention is made.

[0037] The structure of the main plucking ear roller 2 on the top of the A-type roller and the passive plucking ear roller 9 on the top of the B-type roller is a special-shaped polygonal column structure, and the number of edges of the special-shaped multi-edge structure is an even number, and the central angle of the cross section remains No change, the internal angle is adjusted to be one large and one small adjacent two angles, one of the internal angles is adjusted to α+Δ, and the other is adjusted to α-Δ, the Δ≤180 / n, the cross-section of the special-shaped polygonal roller The side is tangent to the circumscribed circle of the regular polygon, and n is the number of edges of the special-shaped polygonal prism; with the special-shaped polygonal...

Abstract

The invention provides a combined corncob picking roller for a corn harvester. The combined corncob picking roller comprises two structures of a roller A and a roller B, the roller A comprises a main roller upper spindle nose, a main corncob picking roller, a main roller lower spindle nose, an auxiliary roller upper spindle nose, a main stalk pulling roller and an auxiliary roller lower spindle nose, the roller B comprises a driven roller upper spindle nose, a driven corncob picking roller, a driven stalk pulling roller and a driven roller lower spindle nose, wherein the roller A is matched with the roller B, staggered matching of a large angle and a small angle is adopted when the roller A is matched with the roller B, the corncob picking parts of the two rollers are both in an abnormal-shape polygon prism structure to guarantee equal-clearance exciting picking in the process of picking a corncob; the stalk pulling part adopts a cone structure with evenly distributed straight flanges, the smoothness of feeding a stalk and the capability of grabbing the stalk are effectively improved, the structure achieves the effect of picking the corncob with low loss and high efficiency, and the combined corncob picking roller for the corn harvester has the characteristics of simple structure and low power consumption.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a combined ear picking roller for a corn harvester. Background technique [0002] At present, there are two kinds of horizontal plucking methods commonly used on domestic corn harvesters, one is the plucking plate type, and the other is the roller plucking ear. Among them, the rib roller type ear picking has a simple structure and small size, and is a commonly used ear picking roller. The rib-type ear picking roller is generally divided into guide section, ear picking section and strong pulling section. The introduction section is a cone structure, which mainly plays the role of guiding the stalks into the gap between the ear picking rollers; the ear picking section is a single helical rib Cylinder, which plays the role of ear picking, the spiral direction of each pair of ear picking rollers is opposite, and they are arranged in a staggered manner; most of the ear...
