Description

[Detailed Description of the Invention] The present invention relates to an apparatus for shredding waste straw discharged from a combine harvester to produce crude drug silage using a waste straw shredding machine and transporting the shredded waste straw.

In recent years, the mechanization of paddy harvesting has led to the rapid use of combine harvesters, and most of these combine harvesters cut the waste straw and leave it to be scattered on the paddy fields.

As a result, dried long straw is in short supply, resulting in high prices, creating competition between livestock farmers and straw processors.

For this reason, there is an urgent need to consider ways to efficiently utilize the herbal medicines discharged from combine harvesters.One example of this is to leave the waste straw tied up using a binding device, and it is also possible to use it as roughage or to use it as herbal medicine silage. Conceivable.

However, in order to make crude drug silage for roughage, the shredded straw must be fed into an airtight storage bag using a blower and sealed immediately, or it must be fed and stored in a mesh storage bag and then transported to a silo, etc. In any case, the large amount of dust generated in this case is a problem, and the equipment such as the use of a cyclone is required to separate the cut straw from the dust-laden updraft. However, this was unavoidable, and there remained a problem when attaching it to a combine harvester or the like.

The present invention was developed in view of the above problem, and includes a resistance wall provided above the discharge port of the lifting tube whose upper portion is curved in an arc, and an appropriate exhaust port provided at the upper part between the resistance wall and the lifting section. An opening is provided to communicate the intake port of the vaulting body located below and the exhaust port through an intake cylinder, and an arbitrary opening is provided in the intake cylinder, and a switching plate having one end pivoted to the opening can be freely vibrated. This invention relates to an exhaust route switching device in a jump lift device, which is characterized in that the exhaust route is pivotably connected to the pump, and the exhaust route can be switched to the intake port side or to the outside side as appropriate.

The embodiment of the present invention will be described below in detail with reference to illustrative drawings. 1 is a combine main body, 2 is a transport body located at the rear upper part of the combine main body 1 for transporting waste straw after threshing process, Added 3 clamping rods.

4 is a large number of blades 5.5 in the length direction of the straw being discharged.
A straw slicing machine with rotary blade bodies 6, 6 arranged side by side.

Reference numeral 7 is located below the straw slicing machine 4 and is arranged along the working width of the rotary blade body 6.6 which is mounted on a shaft inside the straw slicing machine 4, and transports the cut straw to an appropriate position. This is a jumping lifting device that is connected to and connected to a horizontal conveying body 8 formed as shown in FIG. The cut straw is lifted together with the lifting air by the wind raised by the jumping body 9 inside the lifting tube 12 which is mounted on a shaft and extends upward.

The lifting tube 12 is curved in an arc shape at the top, and has a discharge port 13 at the end of the curved portion.
A resistance wall 14 is installed above the 3-way, and a lifting air separation chamber 15 is formed which is wider than the lifting tube 12, and the lifting air accompanied by the cut straw that has been jumped up reaches the lifting air separation chamber 15, expands, and increases the wind speed. It is configured to collide with the resistance wall 14 while weakening it.

Reference numeral 16 denotes an exhaust port that opens at the top of the air-lift separation chamber 15 formed between the resistance wall 14 and the pumping tube 12, and communicates the exhaust port 16 and the intake port 10 through the intake cylinder 17. An appropriate opening 19 is provided above the cylinder 17, a switching plate 20 with one end pivoted to the opening 19 is pivotally mounted, and an appropriate exhaust path is passed through the intake cylinder 17 to the intake port side.
Alternatively, the intake cylinder 17 is closed using the switching plate 20 and the opening 19 is closed.
It is configured so that it can be opened and switched outward.

In addition, 21 is a cut straw storage bag, and 22 is its hanging body.

Next, to explain its operation, the waste straw that is transferred from the combine harvester 1, which is reaping and threshing while moving in the field, is transferred by the transfer body 2 and the pinning rod 3 after the threshing operation is completed, at the terminal end. The straw is released and falls onto the rotary blades 6, 6 of the straw cutting machine 4 located below, and the entire length of the straw is cut at the same time. Then, the lifting air is lifted up by the lifting body 9 of the jumping lifting device 7 installed in series at the end of the transport, and the lifting air is transferred to the lifting cylinder 12.
The air rises inside the air and reaches the air separation chamber 15 from the arc-shaped portion above the air transport cylinder 12, expands rapidly, and collides with the front resistance wall 14 while weakening the wind speed, further weakening the wind speed. At the same time, only the cut straw is sucked in by the jumping body 9 from the upper exhaust port 16 via the suction cylinder 17 and falls from the discharge port 13 under its own weight.

Also, depending on the situation, if you want to release the uplifted air to the outside, use the switching plate 20.
is caused to vibrate toward the intake cylinder 17 side, the intake cylinder 17 is closed, and the opening 19 is opened to release the lifted air to the outside of the aircraft.

As was the case in the past, the waste straw left in the field in bundles or in long straws during the harvesting process with combine harvesters had to be collected by some method, but most of the fields were paddy fields with no footholds. It's bad and you can't carry it out efficiently.

In general, the content of water-soluble sugars is a problem for good fermentation of herbal medicine silage, and normally herbal medicines contain 9 to 10%, but the longer the time left in the field after threshing, the lower the sugar content. This decreases to less than half due to respiration, rainfall, etc., and the contamination of soil and sand also increases.

Therefore, in the present invention, the lifting tube 12 is curved upward in an arc shape.
A resistance wall 14 is provided above the outlet 13, and the resistance wall 14
A suitable exhaust port 16 is opened at the upper part between the and the lifting cylinder 12,
The intake port 10 and the exhaust port 16 of the jumping body 9 located below
At the same time, an arbitrary opening 19 is provided in the intake cylinder 17, and a switching plate 20 with one end pivoted to the opening 19 is pivotally attached to the opening 19 so as to be able to freely vibrate, and the exhaust path is appropriately connected to the intake port. Since it is configured so that it can be switched freely to the 10 side or the outward side, the inside of the lifting cylinder 12 is
The uplifting wind with cut straw that rises and reaches the uplifting separation chamber 15 rapidly expands in the uplifting separation chamber 15, which is wider than the uplifting tube 12, and collides with the front resistance wall 14 while weakening the wind speed. At the same time, the suction action, which is another function of the jumping body 9, causes the straw to be properly sucked into the suction pipe 17 from the exhaust port 16, promoting the separation of the cut straw and the wind, so that the cut straw is drawn downward from the discharge port 13. It is allowed to fall into the storage bag 21 under its own weight, but depending on the situation as described above, for example, in the case of a lift air that does not contain much dust, it expands in the lift air separation chamber 15 and collides with the resistance wall 14 and is cut. The uplifted air separated from the straw can be exhausted from the upper exhaust port 16 and released outside the machine from the opening in the suction cylinder 17, especially when feeding into airtight silage storage bags, etc. Since dust-laden wind does not blow up from inside the bag, the worker can perform work in a sanitary and comfortable manner without being bothered by the dust.

Moreover, even if the device is miniaturized, it can still be sufficiently effective and can be easily attached to a combine harvester, etc. This eliminates the need for a large amount of time to produce crude drug silage, and it is possible to produce crude drug silage at the same time as harvesting with a combine harvester. It is something.

In addition, since raw cut straw is immediately fed into an airtight storage bag and sealed, it is possible to produce herbal medicine silage that is pale greenish-yellow-orange in color and has a pleasant light sweet-sour odor, and is highly palatable to dairy and beef cattle. It has a simple structure and various effects that are truly remarkable, and it also makes a great contribution to livestock farmers and general farmers by making effective use of waste straw.
