Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting screen frame for threshing equipment, and can also be used for threshing equipment such as combines and harvesters.

Conventionally, the handling barrel of a threshing device has a cylindrical tip rotating circumferential surface on the side that supplies the culm and has handling teeth implanted therein, and a net frame surface on the lower surface of the entrance side of the handling chamber that houses the handling barrel. Since the shape was designed to follow the circular upper-shaped handling barrel surface, when feeding the culm into the handling chamber from the inlet side, this sugar part is shaped like a circular handle that is pushed onto the frame surface. Under the threshing action of
Until the tips of the ears are completely on the mesh surface in the handling chamber, they are scattered during the threshing process and are scattered outward from the input section toward the supply section, and moreover, they tend to create a large resistance to the feeding of the tips into the handling chamber. It is something.

The present invention is intended to eliminate such defects, and for this purpose, the following technical measures have been taken. That is, the sorting net (3) frame (4) of the handling chamber (2) in which the handling cylinder (1) is rotatably housed
), the lower edge (5) is used to approach the extension surface of the sorting net (3) at the point corresponding to the supply of the tip of the head, and from this the handling cylinder (1)
High edges (6) at the front and rear parts in the direction of rotation (a)
A net frame supply edge (7) is provided as a section, and a screen frame supply edge (7) is provided as a section.
) has a threshing and sorting screen frame formed on a slope (8) that slopes downward toward the screen (3).

With this configuration, the present invention has the following technical effects. That is, by rotating the handling barrel (1) in the direction of arrow (A), the grain culm is supplied from the inlet culm supply section to the handling chamber (2).
When the threshing action is carried out in the interior, the feeding edge (7) of the sorting net frame at the lower part of the starting end of the handling drum (1) is lower than the high edge (6) before and after this in the sugar section corresponding part. Edge (5
) section, the feeding of grain culms onto the sorting net (3) in the handling chamber (2) of the monosaccharide section reduces the resistance of the rotating handling cylinder (1) and handling teeth. Therefore, the above-mentioned drawbacks can be solved easily and quickly.
Moreover, the culm once supplied into the handling chamber (2) is
) As the threshing process is carried out by rotation, the sugar part also wraps around the handling barrel (1), so the threshing action can be carried out smoothly as before, and the number of cut ears is reduced, and furthermore, the number of grains that have been threshed is reduced. The grains have a high edge (
6) Since the part is formed, the grains immediately after shedding and the handling room (
2) The grains that have gone around the inside do not jump out from the lower edge (5) and can be guided inward.

In addition, in the drawing, the sorting net frame (4) is divided into front and rear parts of the handling cylinder (1) in the rotational direction (B), and the pair of divided sorting nets (3) and frame (4) have the same configuration. good. A frame (4) is provided on the four sides of each sorting net (3).
) part to the threshing body frame (9) by tightening and fixing it with bolts/l/), etc. The screening screen frame (4) forms a circular shape along the handling cylinder (1) and the handling chamber (2), but the screen frame (4) facing the culm entrance side of the handling chamber (2) is used for selection. An inclined plane (8) in the shape of a circular male is formed when it slopes upward from the surface of the separate mesh (3), and both the front and rear ends are lowered, and the lower edge (5) is the same as the surface of the screening mesh (3). At the extension surface or a height close to this, the portion is located at the highest level than the net (3) surface and becomes lower as it reaches the lower edge (5) portion.

Moreover, the frame (4) portion corresponding to the lower edge (5) portion has a slope (
8) may not be formed.

A pair of front and rear sorting mesh frames (4) A low edge (
5) The section is located. This lower edge (5) is the handling room (2)
It is located in the corresponding part of the sugar part of the culm that is supplied to the inside. The front and rear mesh frame supply edges (7) of the lower edge (5) corresponding to the sugar portion are inclined to be set higher in sequence.

It is a cutting edge.

θ gong is the swinging selection shelf under the sorting net (3), ゛・! The straw rack A4 is the straw outlet at the end of the handling chamber (2), which extends onto the straw rack A.

The handling cylinder (1) is rotatably mounted around an axis α0, and one end on the inlet 0 side is formed into a cylindrical shape, and a handling tooth α force is also provided on this surface.

(+8) is a sorting net (3>lower air pressure winch, 0 is a suction dust extractor, both are connected by a sorting air passage (1), and the first gutter is placed under this sorting air passage (1). Qη, a second gutter (A) is provided.

In (c), the stock part of the threshing husk can be held and transferred by the foot chain on the - side of the handling room (2).
and install a culm transfer device inside.

While the grain culm is transferred with the stem part held between the foot chain, the head part is supplied to the handling room (2) from the entrance 06,
The handling cylinder (1) rotates and is threshed, and the culm is removed from the straw outlet Q4.
The grains leak through the sorting net (3) and are sorted on the swinging sorting shelf (6), and the straw waste is discharged from the straw outlet A4 onto the slow rack U1. and sorted.

In addition, as shown in the figure, the lower edge (5) provided at the position corresponding to the sugar part supply is set as the low level, and the higher edges (6) before and after this are arranged in a v-shape so as to be inclined toward the nominative. ), the heaviest tip part becomes the lowest point and the lower edge (5
), the culm is in a well-elongated state, the sugar part is supplied smoothly, and the scattering of grains from inside the handling chamber (2) is reduced.

In addition, the net frame supply edge (7) is a low edge (5) on both sides in order to approach the extension surface of the sorting net (3), and a high edge (5) is formed in the middle of this area.
6) is formed in a desired arc shape, and a pair of mesh frames (4) (4) are formed on a slope (8) that slopes downward toward the surface of the mesh frame supply edge (7) r5 G sorting network (3). ) in the handling room (2), production is simple by combining a pair of mesh frames (4) (4) of the same type, and the lower edge (5) (5) The tip supply inlet to the handling chamber (2) formed on the joint can be configured to be large, and the sugar section can be supplied even more easily.
