Embodiment 1

[0036] A small area grain combine harvester, including a frame and a walking device 4 arranged on the frame, a pneumatically assisted header device 12, a threshing device 11, a cleaning device 7, a pneumatic conveying device 8, a bagging device 6, a hydraulic integrated Device 5, steering control device 10 and engine device 9. The walking device 4 is located at the bottom of the whole machine, and the hydraulic system drives the four wheels to rotate and walk, so as to realize the advance and retreat of the harvester. The pneumatic assisted header device 12 is located at the front end of the complete machine, and the threshing device 11 and the cleaning device 7 are sequentially arranged behind the pneumatic assisted header device 12 . The pneumatically assisted harvesting unit 12 supports and cuts the grains and feeds them together with the stalks and ears to the threshing device 11, and the cleaning device 7 cleans the threshed mixture to separate grain and grass. The pneum...

Embodiment 2

[0046] Different from Embodiment 1, the pneumatic assisted header device 12 also includes a lateral airflow chamber 3, which is connected to the header fan 25 through an airflow hose 124; the side baffle includes a front side Plate 18 and rear side plate 23, the bottom side of described rear side plate 23 is provided with transverse airflow hole 22, and described transverse airflow hole 22 is connected with transverse airflow chamber 3; The falling seed grains are blown to the conveying device I 15 in the middle section.

Embodiment 3

[0048] Different from Embodiment 2, the connecting device of the described connection frame and the elastic cover 43 of the manuscript includes an adjustment bolt 46, a spring I 45 and a stop 44, and the adjustment bolt 46 and the stop 44 are fixed on the frame; The adjusting bolt 46 is connected with the upper end of the elastic cover 43 by the spring I 45, and realizes the adjustment of the tension force between the spring I 45 and the elastic cover 43 by the adjusting bolt 46; Contact, to limit the position of the elastic cover 43 of the draft. By arranging the draft elastic cover 43, the drafts on the draft device 42 are evenly distributed by elastic resistance, which is beneficial to the sufficient separation of residual grains.

Abstract

The invention provides an area grain combine harvester which comprises a walking device, a pneumatic assisting header device, a threshing device, a cleaning device, a pneumatic conveying device, a bagging device, a hydraulic integration device, a driving operation device and an engine device. The walking device is placed at the bottom end of a whole machine. The pneumatic assisting header device is placed at the front end of the whole machine. The threshing device and the cleaning device are arranged behind the pneumatic assisting header device in sequence. The pneumatic conveying device is communicated with an outlet of the cleaning device. The bagging device is placed at the back end of the whole machine and is communicated with the tail end of the pneumatic conveying device. Conveyed seeds are bagged according to area unit quantity. Each time harvesting in one area is over, a corresponding device is operated to carry out seed clearing under a moving-stopping state, and seed mixing between different areas is avoided. Working efficiency is high, the grain breaking rate and the loss rate are low, inner grains can be cleared easily, seed residues are avoided, and the problem that during harvesting, seed mixing is caused by inner residual seeds of machines between different areas is effectively solved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, in particular to a grain combine harvester, in particular to a grain combine harvester suitable for residential areas. Background technique [0002] The plot test is a field comparative test of the selected crop varieties, which is an important part of agricultural crop breeding. This link has a long operation cycle, high precision requirements, and high labor intensity. Realizing the mechanization of plot experiments can greatly improve the efficiency of breeding work, reduce the labor intensity of breeding operations, and improve operation accuracy. Compared with field harvesting, there is a big difference in crop harvesting operations in plots: (1) The area of ​​a single plot is very small; (2) Different crop varieties are planted in adjacent plots, and the seeds in the machine must be cleaned after each plot is harvested Then harvest the next plot to avoid mixing of differ...
