Axial-flow cylinder of harvester

Abstract

The invention discloses an axial-flow cylinder of a harvester. The axial-flow cylinder of the harvester comprises a spindle, five tooth rods uniformly distributed around the periphery of the spindle and trapezoidal teeth radially arranged on the tooth rods. The five tooth rods are fixed around the periphery of the spindle through multiple support boards at intervals. One side, facing a feeding area, of two support boards at two ends is provided with a reinforcing board. The reinforcing board is arranged between each adjacent tooth rods. The teeth on each tooth rod are divided into three sections. Each included angle formed between a large plane of the teeth and the axis of each tooth rod is different. The teeth reversely tilt towards a rotary direction at the degrees of 5 to 10 in the peripheral direction. The axial-flow cylinder of the harvester has the following beneficial effects: grass is arrayed well and long grass is discharged; breaking rate of stalks is low; little material is wrapped; a sifter is light-loaded; arrangement of reinforcing boards makes the structural strength of the cylinder greater so that the axial-flow cylinder is firm and does not loose; and wheat straws do not easily enter a bearing of the spindle.

Description

technical field [0001] The invention relates to a combine harvester, and more specifically relates to an axial flow drum on the harvester. Background technique [0002] In rural areas, farmers have generally used harvesters to harvest wheat and other crops, and the failure rate of harvesters in use directly affects the efficiency of farmers' harvesting operations. In the current harvester, the threshing chamber is the main part. The cleaning rate of the threshing is mainly on the axial flow drum in the threshing chamber, and most of the current axial flow drums have either low torque or high strength. Low, and then the threshing is uneven, it is easy to make the wheat straw, etc. wrap around the drum to form a ball, stick together, and increase the rotation resistance of the drum. Careless stones and other sundries tighten the threshing chamber, which will cause the teeth on the drum to be distorted, directly affecting the cleaning rate. I disclosed an axial flow drum in t...

Problems solved by technology

In the current harvester, the threshing chamber is the main part. The cleaning rate of the threshing is mainly on the axial flow drum in the threshing chamber, and most of the current axial flow drums have either low torque or high strength. Low, and then the threshing is uneven, it is easy to make the wheat straw and other entangled on the drum to form a ball, stick together, which increases the rotation resistance of the drum

If there are stones and other sundries to tighten the threshing chamber, it will cause the teeth on the drum to be crooked, which will directly affect the cleaning rate.

I disclosed an axial flow drum in the patent No. 201520224333.2. After practical application, there are still some disadvantages. The second is that the structural strength is low, the gear rod is easy to crack and fall apart from the drum, and the straw is also easy to get into the bearing of the main shaft
