Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a threshing and sorting device in a threshing machine.

In general, a threshing device, as shown in Figure 1.2, transports the harvested husks using a conveyor chain (1) and a conveyor rail (2), and then threshes them using a handling drum (3). The structure is such that paddy and fine straw waste are discharged downward through the receiving net (4), and relatively long straw waste such as the tips of the grains during threshing are discharged to the outside from all sides.

The paddy and straw waste that are sorted downward through the entire receiving net (4) are collected by a grain sheave (5) that is installed below this receiving net (4) and extends rearward and swings back and forth, and a chaff sheave (
6) The paddy and straw waste are oscillatedly sorted through the straw rack (7), etc., the paddy is collected downward, and the straw waste is discharged from the rear and outside the machine from the dust removal device (8). Ta. Such an oscillating sorting means has a structurally wide space and a complicated mechanism, and if moisture adheres to the grain culm, the handling cylinder (3)
Paddy and straw waste adhere to the receiving net (4) and the mesh of the oscillating sorter, causing clogging, which significantly reduces the sorting capacity and hinders the threshing operation. There were problems such as loud noise.

The present invention was made in view of the above circumstances, and uses a simple and rational means, specifically, a transportation body connected to one threshing section to remove water from a large number of grains through a dewatering device 1. By communicating with one end of the rotary sorting body having grain sorting holes and installing a wind sorting device at the bottom of this rotary sorting body, the problems of the conventional technology are solved, and the sorting function of the rotary sorting body is endless. In addition to greatly simplifying and downsizing the sorting device, we have also provided a threshing sorting device mt--which can completely and rationally eliminate the phenomenon of clogging of the rotary sorting body due to adhering moisture, and can perform efficient sorting. It is something to do.

The invention will now be described in detail with reference to the drawings.

Next, the entire details of the dewatering device If (40) will be explained.

+411 is a rotary dehydration cylinder that has a vertical truncated conical cylinder shape and is equipped with a large number of dehydration holes (+lα) and rotates at high speed.
At the center of this rotating dehydration cylinder (4D), there is disposed a feeder (44) with a spiral shape and a brush structure on the outer periphery, which is attached to a shaft (43) that rotates at a low speed and is supported by an arm (42).
In addition, an umbrella-shaped diffuser (4!9 is attached to the upper end of the shaft (43) to disperse the grains to be thrown in. (4G
) is placed on the outside of the rotating dehydration cylinder (411) for a while.
A cylindrical cover with a frusto-conical shape is disposed through the cover (46), and a water receptacle (47) is provided integrally or separately on the lower edge of the cover (46). In the figure, M+ (49) is a pulley. Dewatering device +4 (# is constructed as described above, the lower part thereof is connected to one end of the rotary sorting body 117).

The diagram S shows a modification of the rotating brush 03 formed in a spiral shape. In addition, Fig. 6 shows a configuration in which the rotating brush G moat rotates in the same direction as the rotating sorting body aη, and the bifurcated drawing shows a configuration in which two rotating brushes C33 are used, and either one of the rotating brushes ( 31 shows an example in which the rotating direction of the rotating sorting body a is opposite to that of the force.

Figure 9 shows the wavy irregularities C#h") on the outer periphery of the screw-shaped carrier C2 attached to the rotating shaft C1)4).
An example is shown in which ft is formed in order to further increase the re-threshing effect of this carrier (c).

, 1'/117. //The embodiment shown in the figure shows another one instead of the screw-shaped conveyor (c), in which the tip is set back with respect to the rotation direction and is tilted with respect to the rotation axis (241), and further, A large number of rods fixed in a twisted state with feeding action (2S; C) are attached to the full rotation shaft (24).In short, when the handling cylinder 03 is in a state where the ear is broken, that is, when threshing, the tip of the culm The paddy is threshed again using the broken paddy and cut into the rotary sorter ([71], and the straw etc. It is not specific to the example.

Figure 2 shows another embodiment of the rotary sorting body an. In this embodiment, the rotary sorting body is entirely tapered, and more specifically, the diameter gradually increases from the paddy supply side to the suction fan (5). This allows the supplied paddy, straw waste, etc. to move along the tapered surface without accumulating on the supply side, improving sorting and discharge efficiency. Although the screw-shaped conveying body (c) is also shown so as to gradually increase in diameter in accordance with the taper of the rotary sorting body aD, this conveying body (251) may also be a straight conveying body as shown in the cross-sectional view.

Next spear/3. A detailed example of the /da diagram will be described.

This example uses a rotary sorting body Qn and a Karakinhan.

The screw conveyor (toward) and the like are arranged parallel to the axis of the handling cylinder a3. In this embodiment, as shown in the figure, the dehydration bag w (4o) and the rotary sorting body are connected by a screw conveyor ci1.

Although each of the above embodiments has been described in terms of a lower level system, it can also be applied to a higher level system. That is, the screw conveyor 001 rotary sorting body (171, KARAKI-) for the handling cylinder.

The present invention is not particularly limited to a lower-class threshing device, since a higher-class type can be implemented by changing the arrangement of the screw conveyor (Cl0) and the like.

Next, the effect will be explained. The grain culms transported to the handling room by the transport chain αυ and the transport rail (121) are handled by the handling cylinder α3.
), and the threshed paddy and straw waste are transferred to the screw conveyor (16) by the rotating action of the tooth extraction (14).
1, and further sent to one side by this screw conveyor A61 and thrown into the upper part of the dewatering device k (4 (I). The centrifugal dehydration action of the rotating rotary dehydration cylinder CD dehydrates the water adhering to the paddy and straw waste, and the dehydrated water is expelled from the dehydration hole (+/a) to the outside, and is absorbed into the inner surface of the cover (46). The water reaches the lower part through the water receiving section (47) and is discharged to the outside.The dewatered rice is also transferred to the brush-structured feeder (
The material is conveyed downward by the four transporters and supplied to one end of the rotary sorting body aη.

The paddy and straw waste sent to the rotary sorter aη are collected through the rotary sorter (1η sorting hole (/7 → more paddy and finer dust, i
Lithium debris, etc. will fall. During the falling process, the falling paddy is sorted by the wind from the winnowing machine (2), and the paddy falls to the bottom and is transferred to the grain lifting device t by the screw conveyor 00.
The recovery body C3aK is recovered through the ant-, and light dust is discharged outside the machine by wind force.

In addition, during threshing, the straw, etc., which is broken into ears and has paddy attached to it, is rotated and conveyed by a screw-shaped conveyor (2511C) installed in the rotary sorter αη, and is removed by sliding contact with the inner surface of the rotary sorter aη. The straw is re-thrested by the rubbing action, and the straw is sent to the suction fan (2η) by the conveyor (251) and discharged outside the machine, and the re-threshed paddy is recovered by the same action as described above.

As described above, in the present invention, the sorting means is a rotary sorting body having sorting holes, as opposed to the conventional swinging sorting means.
The sorting action of this rotary sorting body can be made endless and limitless, and therefore, high sorting efficiency can be obtained with a small rotary sorting body. It is possible to simplify the structure, reduce weight, and reduce costs. In addition, compared to conventional oscillating sorting, there is less vibration noise, making it suitable for threshing sorting equipment such as combine harvesters.

Furthermore, if there is moisture attached to the threshed rice or straw waste, the moisture is removed by the dehydrator, which has excellent features such as not interfering with the sorting action.
