Description

[Detailed explanation of the idea] The present invention relates to a dust sending device for a threshing machine.

In other words, the dust exhaust cylinder is mounted on a shaft in the communication area between one side of the handling chamber having the lower plate type handling cylinder and the upper side of the dust removal chamber equipped with the dust suction device on the upper side, and the dust exhaust cylinder is In a threshing machine configured with a sieve line placed at the bottom of the dust chamber side, when the dust containing the second material is sent from the handling chamber to the dust removal chamber, the tip of the dust sending valve and the rotating exhaust By working together with the dust barrel, it loosens the lumps of waste, and also bounces the grains that are scattered towards the dust removal drum due to the impact of the handling teeth back into the handling chamber, which causes the grains to become dust free. In addition to preventing as much as possible from flowing into the dust removal chamber, the dust suction machine in the dust extraction chamber is used to suck and remove dust, and the second material is properly sorted, and the state of the dust sent to the dust extraction chamber is adjusted according to the amount of threshing and the properties such as dryness and humidity. It is provided with a simple structure so that it can be adjusted.

Next, the embodiment shown in the drawings will be described.

1 is a handling barrel with a tooth extraction 1' mounted inside the handling chamber 2 so as to rotate in a downward manner as shown by arrow A, and a foot chain 8 and a clamping rod 8' are installed above and below in front of the handling chamber 2. Set up opposite.

9 is a crimp net, and below the crimp net, there are grain plates 10 in front and behind it.
．． 10' is installed diagonally, and a dust suction device 3 equipped with a handling port 3' is attached to the upper part of the supply side of the dust removal chamber 4 which communicates with one side of the straw removal side of the handling chamber 2.

In addition, a swing sorting body 11 is provided from below the grain board 10, 10' to the bottom of the dust removal chamber 4, and a pressure winch 12 and a No. 1 conveyor 13 are installed below it. Below is 2
A number conveyor 14 is installed.

Then, a dust exhaust cylinder 5 is mounted on a shaft in the communication area between one side of the straw exhaust side of the handling chamber 2 and the upper part of the dust exhaust chamber 4, and the tooth 5' of the dust exhaust cylinder 5 approaches the tip of the handling tooth 1'. The height of the dust removal cylinder 5 is made to be higher than the handling cylinder axis 1a so that it is close to the height of the suction port 3' on the opposite side, and the dust removal cylinder 5 is rotated in the same direction of rotation as the handling cylinder 1. be equipped to move.

Next, an arc-shaped dust sending valve 7 is installed so as to approach the lower part of the dust exhaust cylinder 5, and the supporting shaft 15 of the dust sending valve 7 is brought close to the rear part of one side of the crimp net 9, and this supporting shaft The dust feeding valve 7, which rotates around the dust removal cylinder 5, is directed directly below the dust removal cylinder 5, and its tip is connected to the dust removal cylinder 5.
In addition, the tip of the dust feeding valve 7 is placed higher than the upper edge of the grain flow board 10', and the tip of the dust feeding valve 7 is arranged in a fan shape in a state where it approaches from the inclined state that closes the gap between the crimp net 9 and this grain flow board 10' to the lower front side. It is configured to be rotatable so that the displacement can be adjusted to close or open the space between the crimp net 9 and grain flow plate 10'.

The support shaft 15 is provided so that it can be rotated and fixed from the outside by an adjustment support 16.

Further, a crimp net 9' located on the side of the dust feeding valve 7 is stretched separately from the crimp net 9, and the crimp net 9' is positioned above the upper end side of the grain flow plate 10'. A floating grain plate 10 is installed as shown in FIG.
The base end is attached to the upper edge of the dust removal chamber 4, and a plurality of knot lines 6 are extended to the upper part of the inside of the dust removal chamber 4.

During the threshing operation, when the waste including the second grain is sent out in the direction of the arrow by the handling cylinder 1 and the handling teeth 1' rotating in the direction of the arrow A, as shown in Fig. 4, it becomes a lump. The dust is stagnant at the tip of the dust-feeding valve 7, is loosened by the teeth 5' of the dust-exhaust cylinder 5, which rotates in the direction of arrow A', and is guided to the tip of the dust-feeding valve 7, where it is energized. The grains that are often sent out below the dust removal cylinder 5 and are scattered by the impact of the handling teeth 1' are bounced back to the handling chamber 2 side by the cooperation of the dust sending valve 7 and the dust removal cylinder 5.

In normal cases, the dust sent out to the bottom of the dust removal cylinder 5 is in the inclined state shown by the solid line in FIG. The second grains are sieved by the node line 6 without falling onto the flow board 10', and the second grains fall onto the second conveyor 14 below. It is discharged.

In this case, the dust is loosened by being combed by the teeth 5' of the dust exhaust cylinder 5, and is guided to the tip of the dust sending valve 7 and sent vigorously to the lower part of the dust exhaust cylinder 5. The second object, which is immediately sent onto the node line 6 and separated from dust such as straw by the above-mentioned loosening action, passes directly between the node lines 6 and falls due to its inertia, and the dust is caught by the node line 6. This is because it is sucked and discharged from the suction port 3'.

Also, if the properties change due to the amount of grain threshing or dry/wet conditions,
The adjustment support 16 is operated to rotate the support shaft 15 to adjust the degree of inclination of the dust feeding valve 7. As shown in FIG. 4, the dust feeding valve 7 changes from the solid line state to the virtual line state. The displacement can be adjusted within the range of , and by this adjustment, the amount of discharge of the waste can be adjusted.

That is, when the amount of grain threshing is small or the grain is overdried, when the dust feeding valve 7 is adjusted to the position of the virtual line, the space between the crimp net 9 and the grain flow plate 10' is opened, but the dust feeding valve is closed. The tip of 7 is higher than the upper edge of grain flow plate 10', and the tip of tooth 5' of dust removal cylinder 5
Because the dust is unraveled and sent out vigorously by the rotation of the grain board 10', the dust mainly reaches the node line 6 without falling onto the flow grain plate 10', but the remaining dust that does not reach the node line 6 After being loosened, the dust falls from between the crimp net 9 and the grain board 10' and is sorted by the oscillating sorter 11, and dust such as straw is discharged from the machine through the suction port 3'. Ru.

In this way, the present invention has the dust exhaust cylinder 5 pivoted in the communication area between one side of the handling chamber 2 having the lower-class handling cylinder 1 and the upper side of the dust exhaust chamber 4 equipped with the dust suction device 3 on the upper side. In a threshing machine configured by arranging a node line 6 below the dust exhaust chamber 4 side of the dust exhaust drum 5,
The dust removal cylinder 5 has a part thereof exposed to the handling chamber 2 from the communication part, and rotates in the same direction as the handling cylinder 1, and is attached to a support shaft 15 provided close to the rear part of one side of the crimp net 9. The installed dust feeding valve 7 is brought close to the dust exhaust cylinder 5 with its direction directly below the dust exhaust cylinder 5,
In addition, the tip of the dust sending valve 7 is installed at a higher level than the upper edge of the grain flow plate 10' so as to rotate in a fan shape while approaching the dust removal drum 5. Since the structure is configured such that the displacement can be adjusted to close or open the space between the two, and the base end of the node line 6 is attached to the upper edge of the flow grain plate 10', the waste containing the second item can be adjusted. When sending dust from the handling chamber 2 to the dust removal chamber 4, the dust becomes stagnant at the tip of the dust sending valve 7 due to the cooperation of the dust sending valve 7 and the rotating dust removal cylinder 5. The lumps are loosened as if being combed by the teeth 5' of the dust exhaust cylinder 5, and guided by the tip of the dust sending valve 7, and immediately sent out vigorously from the higher position onto the lower node line 6 to achieve the above loosening action. The second object, which can be separated from dust such as straw waste, passes through the joint lines 6 due to its inertia and falls, and the dust is caught by the joint lines 6, so it can be sucked and exhausted by the dust suction machine 3 in the dust removal chamber 4. Dust and secondary material collection is well done.

In addition, when the amount of grain to be threshed is small or the grain is over-dried, the amount of dust sent to the dust removal chamber 4 can be reduced by adjusting the displacement of the dust sending valve 7 to the position of the virtual line. 10'
The space between them is opened, and the remaining dust that does not reach the cotton wire 6, which is sent out by the cooperation of the dust exhaust cylinder 5 and the dust sending valve 5, falls onto the grain flow plate 10' and is shaken. Since the dust is sorted by the dynamic sorter 11, it is not directly subjected to the suction action of the dust suction machine 3, unlike the dust that reaches the cotton wire 6, and becomes part of the second prevention of discharge outside the machine.

In addition, the grains that are scattered towards the dust removal cylinder 5 side due to the impact of the rotating handling teeth 1' are bounced back to the handling chamber 2 side by the dust sending valve 7.
This makes it possible to prevent grains from flowing into the dust removal chamber 4 as much as possible.
