Problems solved by technology

[0003] Since 2013, a number of harvester manufacturers in my country, especially in the south, have successively launched small combine harvesters for hilly and mountainous areas. However, due to immature technology, weak manufacturers’ technology, and poor quality control of parts, they have poor field adaptability. , Grain adaptability is poor, harvesting efficiency is low, labor intensity is high, harvesting quality is poor, there have been a lot of returned goods and machines, and even manufacturers have closed

Example Embodiment

[0038] The first embodiment is as follows:

[0039] Such as figure 1 Shown: The main body of the secondary cleaning mechanism is a cyclone separator, which is installed on the combine harvester. The cyclone-separated shell is divided into a cylinder part 1 and a cone part 2 from top to bottom along the axial direction. A spiral impeller is installed inside the separator along the axis, and the impeller is driven by a motor.

[0040] The cylinder 1 is provided with a transverse feed port, which is connected with the combined harvesting thresher through the agitating cage conveyor 3. After passing through the thresher, the grain is conveyed to the feed port via the agitating cage conveyor 3. Go inside the cylinder 1. A steel wire filter is installed inside the cylinder 1 along its cross section. The steel wire filter is located above the impeller. After the grain enters the cylinder 1, the steel wire filter is used to filter and coarsely select the larger particles. On the net, gra...

Example Embodiment

[0042] Example two figure 2 , 3 , 4 said:

[0043] Such as figure 2 As shown, the standing-riding console includes a console fixed by a console fixing frame, a collapsible station board connected to the console fixing frame, and a collapsible seat connected to the console fixing frame, the console Including a left steering operating lever 30, a right steering operating lever 31, a threshing operating lever 32, and a walking operating lever 33. The left steering operating lever 30 and the right steering operating lever 31 are used for steering through the gearbox 17; the threshing operating lever 32 operates the clutch Power is provided for the threshing components; the walking operating lever 33 operates the clutch to provide power for walking.

[0044] Such as image 3 As shown, the folding station board of the standing-riding operation platform includes a concave-shaped station board 11 with an opening, a stop bar 12 welded to the operating platform fixing frame 1, and a stop b...

Abstract

The invention discloses a miniature combine harvester which is good in harvesting quality. The miniature combine harvester comprises a body and a cleaning mechanism arranged on the body. The miniature combine harvester is characterized in that the cleaning mechanism comprises a cyclone separator arranged on the combine harvester, a shell of the cyclone separator is divided into a cylindrical part and a conical part from top to bottom in the axial direction, and helical impellers are axially arranged inside the cyclone separator; a vertically-upward air outlet and a transverse feed port are formed in the cylindrical part, a discharge port is formed in the lower end of the conical part, and vent holes are formed in the shell wall, close to the discharge port, of the conical part; the feed port is connected with an output port of a threshing device, and the air outlet is connected with an input port of the threshing device. Some cereal grain which is not plump and moves along with airflow can be secondarily cleaned, and the cereal grain is prevented from being discharged as impurities. Accuracy of impurity removal is improved, and the cleaning effect is improved.

Description

technical field [0001] The invention relates to an agricultural harvesting machine, in particular to a small combine harvester. Background technique [0002] Harvesters are one of the agricultural machinery supported by my country. Due to the late development of agricultural machinery in my country, the technical level is relatively backward compared with developed countries. In addition, the supporting technology of my country's harvester industry is backward, resulting in the low technical level of the overall harvester industry. The basic technical requirement of the harvester is to ensure the smooth and efficient operation of the grain under the condition that the technical indicators stipulated by the state are met. [0003] Since 2013, a number of harvester manufacturers in my country, especially in the south, have successively launched small combine harvesters for hilly and mountainous areas. However, due to immature technology, weak manufacturers’ technology, and poo...
