Description

[Detailed description of the invention] The present invention relates to a threshing machine mounted on a traveling machine base such as a combine harvester or a harvester, and more specifically, a grain rocking machine is installed below the handling chamber along the axial direction of the handling barrel. When grains are handled by the sorting body and sorted by swinging toward the wind sorting chamber at the rear in the axial direction of the barrel, even if the machine tilts to the left or right, the grains are not biased to one side of the grain swinging sorting body. The present invention relates to a threshing machine that can oscillate and sort grains in uniform layers on both sides without bunching together.

Generally, there is a wind selection chamber at the rear of the handling cylinder in the axial direction,
In a threshing machine that is equipped with a grain oscillating sorter that oscillates and sorts the grains along the axial direction of the handling barrel toward the wind sorting chamber below the handling chamber, when the machine body is horizontal, The grains form a layer of uniform thickness on the oscillating sorter, allowing for smooth oscillating transport and sorting, but if the machine is tilted from side to side in a sloping field, etc., the downward slope side of the oscillating sorter may On the other hand, the grains gather unevenly on the slope, forming a thick layer, while on the upward slope side, the layer becomes thinner, which reduces the shaking sorting effect and increases the number of secondary reduction products. The disadvantage is that there are many scattered objects because they pass through in a concentrated manner.

The present invention was devised in view of the above-mentioned circumstances, and the grains are transferred to the oscillating flow plate formed on the proximal end side of the oscillating grain sorter, positioned approximately at the center in the left and right width direction. The front and rear panels are used to guide and guide the grains.
The rear end of the grain rocking flow plate is pivotally connected to be rotatable across the left and right widths of the grain rocking flow plate, and the rotating movement mechanism of the board is connected to an inclination sensor that detects the inclination of the machine body. By configuring the board so that it can be switched to the downward slope side of the grain rocking flow plate in response to the left and right inclination of the machine body, even when the machine body is tilted left and right in a sloping field, etc., grains, etc. The material to be sorted can be oscillatedly transferred and sorted on the oscillating flow plate as a layer of uniform thickness on the left and right sides, allowing for smooth sorting without increasing the number of reduced substances or the number of scattered substances.

The second matter such as the cut grain culms and straw waste remaining on the top is discharged from the tip beyond the rear end of the first gutter 14 by the swinging transfer action, and is further sent to the bottom where the air is blown through the auxiliary wind selection passage 15b. The cut grain culm and straw waste are re-selected while being guided to the wind sorting room 17 by the pressure of the winnowing machine 16, and the cut grain culm is returned through the second conveying throat 18a and subjected to rocking sorting again. The straw waste is discharged from the wind selection chamber 17 to the rear of the machine.

By the way, when the machine body tilts to either the left or the right in a sloping field, etc., in the present invention, the terminal 30 of the tilt sensor 28 is energized to sense the tilt, and the solenoids 24 and 25 are immediately activated to move the top plate 19.
is rotated to the downward slope side, and its tip comes into contact with the side plate 10a of the oscillating flow plate 10, so that the material to be sorted leaked from the receiving net 3 onto the oscillating flow plate 10 is removed from the oscillating flow plate. 1
0 tends to gather on the lower side of the flow plate 19, but it is swung up and guided to the higher side of the oscillating flow plate 10 along the inclined surface of the rotated plate 19, and a part of the flow plate 19 Therefore, even if the machine body tilts to one side, the grains do not gather on one side of the rocking sorter 13 as in the conventional case, and the tip of the board 19 that is in contact with the side board 10a Since the material to be sorted does not get stuck or sag, it is smoothly transferred onto the crimp net 12 in a layer having a uniform thickness on the left and right sides. Therefore, the sorting work can be carried out smoothly without any particular increase in the No. 2 reduced products and No. 3 scattered materials.

In short, the present invention has a wind-selecting chamber at the rear in the axial direction of the handling barrel, and the grains are oscillatedly transferred toward the wind-selecting chamber side along the axial direction of the handling barrel at the bottom of the handling chamber. In a threshing machine equipped with a grain shaking sorter for sorting,

The movable flow plate is pivotally connected to be rotatable across the left and right widths of the swing flow plate, and the pivot plate rotation mechanism is connected to an inclination sensor that detects the inclination of the aircraft body. The oscillating flow plate can be switched to the downward slope side in response to the left and right inclination of the machine, so even if the machine tilts to either the left or right in a sloping field, the tilt sensor will detect the inclination of the machine. is sensed and the board is immediately switched to the downward slope side across the left and right width of the oscillating flow board, so that the sorted material leaks from the handling net and tends to collect on the lower side of the oscillating flow board. To smoothly swing up and guide an object to the higher side of a swinging flow board without being hit by the board. Therefore, it is possible to prevent the materials to be sorted from gathering on one side of the grain oscillating sorter, and to sort and transfer them as a layer with a uniform thickness on both sides, thereby reducing the number of reduced materials and the number of scattered materials. This has an extremely useful practical effect of allowing the sorting work to be carried out smoothly and improving the sorting performance.
