Description

Harvester roller

Technical Field

The utility model relates to a combine, more specifically say so and relate to a harvester cylinder.

Background

The fault rate of harvester in use directly influences the efficiency of the reaping operation of the peasant, the threshing chamber of the harvester is a main part, the clean rate of threshing is mainly on the axial flow roller in the threshing chamber, and in the existing roller, because the distance between the inner wall of the threshing chamber and the outer diameter of the roller directly influences the grain running problem of the grass outlet, the grain running carried by the grass outlet influences the harvest rate of the grain, and the grain running carried by the grass outlet has a direct relation with the gap between the inner wall of the threshing chamber and the outer diameter of the roller, the inner diameter size of the inner wall of the existing threshing chamber is not fixed, according to the difference of vehicle types, the inner diameters are different, so the fixed roller diameter is difficult to meet the grain collecting requirement.

Disclosure of Invention

In order to overcome the defects existing in the prior art, the utility model provides a harvester roller.

The utility model discloses a realize through following technical scheme: the utility model provides a harvester cylinder, includes the five ratchets of cylinder periphery equipartition, sets up ejection of compact district and breaks away from the disengagement zone on the cylinder, be provided with the separation board on the ratchets in ejection of compact district, the separation board is radial setting and face and ratchets axis parallel on the ratchets, and the separation board can be adjusted along the radial of cylinder.

In the above scheme, each toothed bar is provided with one separating plate, and the separating plates are arranged on the toothed bars in the discharging area in a mutually staggered mode along the axis of the roller.

In the scheme, the rack bar is provided with the separation plate fixing teeth, the separation plate fixing teeth are provided with the long slotted holes along the radial direction of the roller, and the separation plate is fixed on the long slotted holes through screws and nuts.

In the scheme, the separation plate fixing teeth on the five rack bars are sequentially arranged according to the number of 3, 4, 5, 3 and 5 along the circumference of the roller, the separation plate fixing teeth on the same rack bar are arranged at equal intervals, and two separation plate fixing teeth are arranged on the rack bars of the 5 separation plate fixing teeth and are positioned in the separation area.

In the scheme, the fixed teeth of the separation plate are bent into a U shape by using a metal rod, and two legs of the fixed teeth of the separation plate are welded on the rack rod.

In the scheme, the two screw holes are formed in the separating plate, and the distance between the hole distance and the distance between the two adjacent separating plate fixing teeth are equal.

In the scheme, the separating plate is fixed on the separating plate fixing teeth through the ball head screws, the flat pads, the elastic pads and the nuts.

Compared with the prior art, the harvester roller has the beneficial effects that:

1. the separation plate on the roller can be adjusted along the radial direction of the roller, and different inner diameter sizes of the threshing chamber can be met, so that the gap between the separation plate and the inner wall of the threshing chamber is adjusted to be 1.3 cm.

2. The separating plate on the roller has two separating plates which can move to the position of the middle concave plate of the threshing chamber, so that the flow distribution is smoother.
