Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used in a sorting section of a threshing machine, and particularly relates to a water draining device for a swinging sorting plate provided in the sorting section.

[Prior art]

Conventionally, there has been no water draining device provided on the swinging sorting plate provided in the sorting section.

[Problem that the invention attempts to solve]

In conventional threshing machines, when washing the machine or threshing wet materials, if water collects in the lower part of the swinging sorting plate, the water will adhere to the materials to be sorted, impairing sorting, or cause rust or rust on the component parts. There were defects such as corrosion.

The technical problem of this invention is to remove the water on the sorting plate by providing a drainage hole in the swinging sorting plate, and to quickly drain the water out of the machine without accumulating it inside the machine. .

[Means for solving problems]

In order to solve the above problems, the water draining device for the sorting section of the thresher according to the present invention is as follows.

In the sorting section of the thresher, which has a wind direction plate 26 for the sorting air from the pressure fan 14 arranged below the swinging sorting plate 18, the swinging sorting plate 18 has a sorting net 20 connected to its tip. The wind direction plate 26 is provided with a drain hole 18a on the tip side, and the wind direction plate 26 is connected to the air outlet 14 on the outer wall of the pressure fan 14.
(b) The upper edge portion is bent and extends upwardly to face below the drain hole 18a, and the bent portion is used as a water reservoir recess 27, and drainage is communicated with the water reservoir recess 27 on the side wall 4 of the fuselage. It is characterized in that a hole 28 is provided.

[Effect]

The water on the swinging sorting plate 18 passes through the drain hole 18a,
The water falls onto the wind direction plate 26, passes through the water reservoir recess 27, and is quickly discharged from the drain hole 28 to the outside of the machine.

〔Example〕

An example of the present invention will be described based on the drawings.
1 is a suction chamber of the threshing machine, which includes a front wall 2, a rear wall 3, a side wall 4 on the stock side, a side wall 5 on the ear side, a cylinder cover 6,
It is surrounded by a receiving net 7, etc., and a handling cylinder 8 is rotatably installed inside.

10 is a suction port provided on the side wall 4; a supply port provided on the front wall 2 and a discharge port provided on the rear wall 3 are communicated via the handling port 10; is supported. 12 is a straw removal chain provided behind the feed chain 11, and 13 is a dust removal fan provided below it.

14 is a pressure fan installed below the starting end of the handling room,
A swinging sorting body 16 that swings back and forth is installed in a sorting section 15 that extends from the fan 14 to below the dust removal fan 13.

The swinging sorter 16 is composed of a dust sorting shelf 17, a swinging sorting plate 18, a first receiving plate 22, a second sorting shelf 23, and the like. The swinging sorting plate 18 has its base located below the starting end of the handling chamber, and its tip is inclined downward to receive leakage from the receiving net 7 and transfer it to the rear. As shown in Figure 2, the feed chain side is lowered by a gentle inclination θ in the lateral direction, and a drain hole 18a is provided on the lower side, into which a drain plug 21 made of an elastic material can be detachably attached. It is fitted. At the tip of the swinging sorting plate 18, a wavy transfer plate 19 is provided which is gently sloped so that the rear side is slightly higher, and a sorting net 20 is provided following this. At the bottom of the sorting section 15, there is a first receiving gutter 24 below the sorting net 20, and a second receiving gutter 2 below the second sorting shelf 23.
5 are arranged respectively.

Reference numeral 26 denotes a wind direction plate provided below the swinging sorting plate 18, which is integrally formed with the outer wall 14a of the air pressure fan 14, and is connected to the air outlet 1 provided at the lower part of the outer wall 14a.
4b is formed by extending the upper edge thereof and bending it upwardly, and its free end faces downwardly from the drain hole 18a. A water reservoir recess 27 is formed by the winnowing outer wall 14a and the wind direction plate 26.

28, 28 are provided on the side walls 4, 5 and the water reservoir recess 2
7, which has a curved edge 28a protruding inward as shown in FIG. It is attached to the side walls 4, 5 in a state where it is in contact with this curved end 28a.

In other words, the drainage hole 28 and its curved end 28a are
Side walls 4 such as the air pressure fan outer wall 14a and the wind direction plate 26,
This is also used when assembling a plate spanning between 5 parts to the side walls 4 and 5 by spot welding, and the positioning pins of the welding jig are inserted into the drain holes 28 to position the wall sides 4 and 5 with respect to the jig. Further, the curved portion of the water reservoir recess 27 is brought into contact with the curved edge 28a, and the pressure fan outer wall 14a and the wind direction plate 26 are positioned and welded together with respect to the side walls 4 and 5.

4a is an opening provided in the outer wall 4 on the stock side; 29 is a lid attached to the opening 4a so as to be openable and closable;
The drain plug 21 can be attached and detached via a.

The present invention is constructed in this way, and the swinging sorting plate 1 is used when threshing wet materials or washing the machine.
8, when water collects in the drain valve 21, remove the lid 29 and remove the water drain valve 21.
You can easily remove the accumulated water by pulling it out.

That is, the water accumulated on the swinging sorting plate 18 is drained from the water drain hole 18.
a and falls onto the wind direction plate 26, passes through the water reservoir recess 27, and is quickly discharged from the drain hole 28 to the outside of the machine.

The one shown in FIG. 4 is another embodiment, in which the oscillating sorting plate 38 is provided with a large number of holes 38a smaller than the shell grains, so that water that tends to accumulate on the oscillating sorting plate 38 can be removed. leaks from the hole 38a, falls onto the wind direction plate 26, and is discharged from the outlet 28. In addition, an auxiliary air outlet 34c is provided above the water reservoir recess 27 of the pressure fan outer wall 34a, and the air blown from this air blows through the hole 38a, thereby preventing the hole 38a from becoming clogged. Never.

[Effect of idea]

This invention allows the water that collects on the swinging sorting plate to leak out from the drain hole, so that good sorting can be achieved without water adhering to the sorted items and adversely affecting the sorting. Since the water leaking from the drain hole is caught by the wind direction plate and quickly discharged from the water reservoir recess through the drain hole to the outside of the machine, the structure is simple and rusting of the component parts is prevented.
This has effects such as being able to prevent corrosion.
