Embodiment 1

[0044] The working process of embodiment 1:

[0045] When the combine harvester starts to work, the material is fed into the threshing device through the conveying trough, and collides and rubs against the concave screen under the high-speed impact on the threshing drum to achieve threshing. When the combine harvester was working as normal, the upper part 401 of the radial backguy and the tangential backguy 8 were all in a tensioned state, and the grid bar was clamped, as Figure 9 As shown in the figure, under the positions of the grid bar 1 and the threshing cylinder 12, the threshing gap is L 1 ; but in the actual operation process, the feeding amount will fluctuate with the distribution density of the field crops. When the feeding amount is too large or fluctuates, it will directly cause the load of the threshing drum 12 to change, and in severe cases, it will cause the threshing drum 12 Blockage and stop. When it is detected that a blockage is about to occur, the upper s...

Embodiment 2

[0046] Example 2 as Figure 4 , Figure 5 and Figure 7 As shown, the threshing device with adjustable two-way pull wire threshing gap according to the present invention includes a tension mechanism, which includes an elastic gasket 2, a guide pulley 3', a radial pull wire 4, a chute 5', and an A pull rod 6' , electric push rod 7', tangential stay wire 8 and B pull rod 9'. The grid bar 1 is installed in the hole of the side plate 10, and the grid bar 1 has a certain gap in the radial and tangential directions, which is convenient for the grid bar 1 to move in the radial direction, and then adjust the threshing gap. There are holes along the radial direction on both sides of each grid bar, and several tangential holes are equally spaced in the middle. On both sides of the concave plate, the radial direction of the grid bar 1 is respectively arranged with the A upper rod 601' and the A lower rod 602', and one end of the radial pull wire 4 passes through the radial hole of the...

Abstract

The invention provides a threshing device with an adjustable two-way drawing wire threshing interval and a combined harvester. The device comprises grid strips and a tensioning mechanism, wherein a plurality of grid strips are in clearance fit with a side plate, the tensioning mechanism is installed on the multiple grid strips, and the grid strips move radially and tangentially in clearances. Thetensioning mechanism comprises tangential tensioning devices and radial tensioning devices, and one radial tensioning device is installed in the radial direction of any grid strip for enabling the grid strips to move in the radial direction in the clearances; the tangential tensioning devices are installed on the grid strips in the tangential direction in series for enabling the grid strips to move in the tangential direction in the clearances. According to the actual harvesting operation conditions, the size of the threshing clearances can be adjusted by adjusting the positions of the grid strips, the adjusting mechanism is simpler, operation is convenient and rapid, and the concave plate clearances can be easily adjusted and controlled automatically, and the problems that existing threshing clearance adjustment is difficult and the automatic degree is low are solved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a threshing device and a combine harvester with adjustable two-way cable threshing gaps. Background technique [0002] The threshing device is one of the core components of the combine harvester. Its main function is to remove the grain grains from the stalk. The performance of threshing directly affects the working efficiency and performance of the combine harvester. The size of the gap between the concave plates is also To a certain extent, it affects the quality of grain harvest. Due to the fact that the combine harvester is in the actual operation process, the planting conditions of the grain are different and the field environment is different, which will cause the feed amount of the combine harvester to be too large or the feed amount to change suddenly, so it is easy to cause faults such as clogging of the threshing drum. The traditional solution is generally to stop...
