Description

[Detailed description of the invention] This invention is a thresher-type pulse threshing machine for threshing beans such as soybeans, in which a processing barrel is mounted on a storage shaft below a processing barrel chamber where a storage shaft is mounted. This invention relates to improvements to a pulse threshing machine having a body chamber.

The pulse threshing machine of the above-mentioned type threshes grain culms that are introduced into the processing barrel using a rotating processing barrel, and the resulting threshed product is received in the processing barrel. The threshed material that has leaked through the net is reprocessed by a rotating processing drum in the processing drum chamber below the receiving net, and this reprocessed material is passed through a sorting screen in the processing drum chamber to sieve out the threshed beans. However, if the grain culm of the beans to be threshed has a high moisture content, the beans to be taken out may be
There is a problem in that the surface becomes dirt particles covered with mud.

The present invention was developed to solve this problem, and even when grain culms with a high moisture content are subjected to threshing treatment, the threshed grains can be harvested in a clean state with no mud adhering to the surface. The purpose of the present invention is to provide a pulse threshing machine that enables the extraction of beans.

The present invention was completed based on the results of various studies and experiments for the above purpose.

In other words, when there is a lot of moisture, the grains that are taken out become dirty grains with mud attached to the surface. A large amount of mud adhering to the processing barrel leaks through the receiving net of the handling barrel along with beans, grain culms, and crushed grain debris, enters the processing barrel, and is collected together with beans and crushed debris in the chamber. When the beans begin to rotate, they are kneaded into a clay-like form by the large amount of moisture and adhere to the sorting net that forms the peripheral wall of the processing barrel, and the beans are shed and rotated inside the processing barrel. This is because the clay-like mud that has been kneaded into a clay-like shape is rolled onto the surface of the beans as they roll in contact with the mud that is attached to the sorting net. This problem can be solved by making the beans come out of the processing barrel faster, and this can be done by reducing the amount of threshed grains that leak through the receiving net of the processing barrel and flow into the processing barrel. , remove the radish (salt husks with peas attached) that need to be reprocessed,
It was found that the beans, which had already separated from the carcass and fell into the processing barrel in the form of single grains, could be discharged as they were outside the processing barrel, and then fed into the processing barrel from the supply port. Most of the grains that are easily separated into single grains fall from the chaff at the position where the grain culms are fed into the handling chamber from the supply port, and are transferred to the culm outlet side of the handling chamber. As a result, the grains, which are difficult to separate, fall off from the grain culm in the form of grains along with the chaff, and the grains are reprocessed in the processing barrel. The threshed material that leaks through the receiving net of the handling barrel chamber and falls onto the lower part of the starting end side near the supply port where the grain culm is inputted into the handling barrel chamber is directly transferred to the sorting net. This is because when we installed an opening that penetrates the lower part of the body, we were able to significantly reduce the proportion of dirt particles in the beans being taken out, without significantly affecting the threshing process.

For this reason, in the present invention, a processing barrel chamber in which the processing cylinder is mounted on the storage shaft is installed below the receiving net of the processing barrel room in which the processing drum is mounted on the storage shaft, and a sorting screen in the processing barrel room is installed. In a pulse threshing machine, a wind sorting section is installed at the lower part of the body, and a supply port is provided on the starting end side of the peripheral wall of the handling barrel in the direction in which the grain culms are transferred by the handling barrel. Openings are provided at the lower part of the starting end side of the sorting net near the supply port of the handling barrel chamber, through which the processed material that leaks and falls from the receiving net of the handling barrel chamber drops downward. However, the present invention proposes a means for attaching a lid body to the opening in a detachable manner.

Next, an example of implementation will be described in detail with reference to the drawings.

A conveyor 81 that transfers the selected items to the sorting air path 80
This is a normal type consisting of a Karachi blower 82 that supplies the sorting air to the sorting air passage 80, and an Ichiban screw 83 installed at the bottom part of the sorting air passage 80, and the end of the sorting air passage 80. The section is opened to the outside through an opening 84.

Next, the operation of the pulse threshing machine according to the present invention constructed as described above will be explained.

When threshing grain culms with high moisture content,
Either the opening 6 provided in the sorting net 5 of the processing barrel chamber 3 is left open, or a lid 73 with a large opening ratio is attached to the opening 6 as shown in FIG. Carry out work with most of the holes open.

Then, when the grain culm is fed into the handling barrel chamber 1 from the supply port 10 and a prescribed threshing operation is performed, the grain culm has reached a stage of ripening and will burst out of the husk with the slightest shock. Most of the beans that separate from the grain culm as soon as they are introduced into the barrel chamber 1 leak through the receiving net 12 of the handling barrel chamber 1, as shown by the arrow in FIG. When the grains flow down into the processing barrel chamber 3, the grains pass through the processing barrel chamber 3 as they are through the openings 6 provided in the sorting net 5 of the processing barrel chamber 3, and the grains pass through the processing barrel chamber 3 as they are through the openings 6 provided in the sorting net 5 of the processing barrel chamber 3. It will start to fall into selection section 8.

As a result, beans that have already been separated from the grain culms in the processing barrel chamber 1 and do not require reprocessing in the processing barrel chamber 3 roll around in the processing barrel chamber 3 unnecessarily and are kneaded into a clay-like form. Since the peas are not coated with mud, the number of dirt particles in the peas taken out from the take-out port (first screw 83) is significantly reduced.

At this time, the opening 6 is connected to the supply port 10 of the handling barrel chamber 1.
The threshing action of the grain culm at the starting end side of the handling barrel chamber 1 causes the grain culms that are easily shattered to drop from the grain culm, and the grain culms are removed from the grain culm at the terminal end side of the handling barrel chamber 1. Since there is almost no falling off of the beans, there is almost no chance that the beans will be fed to the wind sorting section 8 through the opening 6, There is almost no hindrance to the threshing processing function.

In addition, when the grain culm to be threshed is sufficiently dry and has low moisture content, a cover body 70 formed in the form of a blind plate is attached to the opening 6 to close it, making it possible to remove the grain from the conventional pulse threshing machine. It will be used as.

As explained above, according to the present invention, when threshing a high-moisture grain culm, the legumes that have fallen off from the grain culm at the starting end near the supply port in the handling barrel are stored in the lower part of the handling barrel. This method prevents the clay-like mud from being smeared in the processing barrel by passing through the processing barrel and falling into the wind sorting section. It becomes possible to significantly reduce the proportion of dirt particles whose surfaces are coated with mud among the beans taken out from the take-out port without causing any major hindrance to the function.
