JPH0365118A - Grain culm feeder in thresher - Google Patents

Abstract

PURPOSE:To provide the title feeder intended to put grains to complete threshing treatment in high efficiency, so designed that the root of grain culms is gripped and carried and an ear tip side is introduced into a handling chamber to thresh the ear tip parts, and the whole culm is then drawn into the chamber in succession through the relevant port to thresh the grains attached to the culm root. CONSTITUTION:An L-shaped handling port 4 in a planar view is opened between the grain culm feed side (a) of a handling chamber 1 and an intermediate part (c) along the front of the chamber 1. The root of grain culms is then gripped and carried by a relevant device (d) and the ear tip side is introduced through the port 4 into the handling chamber 1 to first thresh the ear tip parts. Thence, the grain culms passed through the device (d) are successively introduced, in its entirety, while releasing the gripping, through the relevant port 5 into the chamber 1 to thresh the grains attached to the root. Subsequently, the waste culms threshed are discharged off the thresher through the culm-discharging side (b), and the resulting product from threshing treatment in the chamber 1 is fed to a grading section 3 where said product is graded.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial field of application The present invention relates to a handling chamber in which a handling cylinder shaft is horizontally mounted from a culm supply side on one side to a culm discharge side on the other side, and A threshing machine consisting of a sorting section that sorts the wholesale material from the handling room,
This relates to a shell culm supply device that supplies the shell culm to a handling room when threshing buckwheat, etc., in which grains are attached all over the culm from the culm side to the ear side. It is.

(b) Prior art The above-mentioned threshing machine is known, for example, from the Utility Model Publication No. 60-11463.
There is no need to mention that this is well known from Publication No. 9, etc., and in this publication, a foot chain and a clamping rail are installed vertically in front of the handling room to clamp the culm. A technique has been added in which a pinching and conveying device for conveying is provided and a pinching rail portion constituting the terminal end portion of the pinching and conveying device is configured so as to be able to be separated from the foot chain.

(c) Problems to be Solved by the Invention The present invention provides a handling chamber in which a handling cylinder shaft is horizontally mounted from the shell culm supply side on one side to the culm discharge side on the other side, and A threshing machine consisting of a sorting section that sorts wholesale products
When threshing products such as buckwheat that have grains attached all over the culm from the culm side to the tip side, the culm can be easily fed to the handling room. This was created for the purpose of providing a threshing machine equipped with a husk feeding device that prevents grains attached to the base side from being discharged to the culm discharge side without being threshed. .

(d) Means for Solving the Problems Therefore, in order to achieve the above-mentioned object, the present invention aims to horizontally move the handling cylinder axis from the culm supply side on one side to the culm discharge side on the other side. In a threshing machine consisting of a suspended handling chamber and a sorting section for sorting the materials handled from the handling chamber, a husk culm supply side of the handling chamber and a front side of the handling chamber are provided with a husk culm supply side and a middle section. While opening the L-shaped handling port in plan view,
At the front side of the handling chamber on the culm supply side, a clamping and conveying section for clamping and conveying the shell culm from outside the handling chamber into the handling chamber is provided at the handling opening, and a handling opening section that opens between the clamping and conveying section and the midway part. was constructed at the shell culm intake port.

(E) Function With this configuration, when threshing is performed by placing soybeans on a stand connected to the culm supply side, for example, the culm side of the placed soybeans is fed to the clamping and conveying section. Then, the soybean ear tip side enters the handling chamber from the handling opening on the husk culm supply side by the clamping conveyance of the clamping conveyance section, and the ear tip portion is first threshed. The culm that has passed through this clamping and conveying section is not released from the grip on the culm side as it passes through, and the entire culm is sequentially taken into the handling chamber from the culm intake port and grains are deposited on the culm side. The grains in the grain are threshed, and the threshed waste culm is discharged from the culm discharge side to the outside of the machine, and the waste material from the threshing process in the handling room is sorted by the sorting section.

) (34), remove the opposing member (36) located below the foot chain (33), and replace it with the conventional pinching rail (39) as shown in Figure 4, the culm side will be It is sandwiched between the foot chain (33) and the pinch rail (39) and is transported from the culm supply side (a) to the culm discharge side (b) for threshing. This is a versatile threshing machine that can not only be used to thresh rice and wheat, but also rice and wheat.

(g) Effects of the Invention As detailed above, the present invention provides a handling chamber in which a handling barrel is horizontally mounted from the culm supply side on one side to the culm discharge side on the other side, and the handling chamber. In a threshing machine comprising a sorting section for sorting the raw material from the husks, the husk supply side of the handling chamber and the front side of the handling chamber are L-shaped in plan view from the husk culm supply side to the middle part. In addition to opening the handling port, a clamping and conveying section for clamping and transporting the shell culm from outside the handling chamber into the handling chamber is provided at the front side of the handling chamber on the culm supply side, and a gap between the clamping and conveying section and the intermediate section is provided. Since the shell culm intake port is a handling opening that opens at During conveyance, the tip side enters the handling chamber from the handling port on the culm supply side and the tip portion is threshed, and the grains that pass through this clamping conveyance section are released from the clamping on the culm side and then go to the culm intake port. The whole culm is taken into the handling room one by one and the culm side is threshed, so it is possible to remove grains from the culm side to the tip side, such as soybeans and buckwheat. During threshing, it not only makes it easier to feed the shell culm to the handling room, but also completely threshes grains that have settled on the culm side, preventing losses due to unhandled grains. It also made it possible to do so.
