DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a threshing apparatus.

[0002]

2. Description of the Related Art Conventionally, a threshing apparatus is disclosed in Japanese Unexamined Patent Publication No. 7-312.
As disclosed in Japanese Patent Publication No. 970, a receiving net is stretched below the handling cylinder to allow the grains to leak from the receiving net onto a swinging sorting plate, and to remove straw and the like from the rear of the handling chamber. It was discharged from the dust port. And the 2nd reduction | restoration apparatus was comprised so that the 2nd processed material may be reduced to the starting end side of a rocking sorting board, and a grain may be collect | recovered by rocking sorting.

[0003]

According to the above-mentioned conventional construction, a large amount of waste chips and the like are contained between the handling drum and the receiving net in the latter half of the handling room, so that the grains are hardly separated and leaked. Had become. As described above, the second processed material was rock-sorted to collect the paddy, but the grains mixed with straw and the like were not sufficiently collected by rock-sorting alone, and It was difficult to separate and collect the paddy from the branches by rocking sorting.

[0004] The present invention has been made in view of the above circumstances, and an object thereof is to increase the recovery rate of grains.

[0005]

[Means for Solving the Problems]

[Structure] The feature of the invention according to claim 1 is that, on the latter half side of the handling room, on the lateral outer upper side opposite to the handling opening, the processed material reaching the latter half of the handling room is received and reprocessed. A first processing cylinder and a first processing in which the reprocessed material is subjected to leakage sorting on an oscillating sorting plate.
A second receiving net is provided along the handle cylinder, and the second half of the first half of the handling chamber, on the lateral outer side opposite to the handling port, receives and processes the second processed material from the second reduction device. Processing cylinder and its 2
And a second receiving net for leaking and sorting the processed material on a swinging sorting plate,
A first exhaust port is provided at a position lower than the first processing cylinder along the handling cylinder to form a first exhaust port on the rear end side of the apparatus, and a first exhaust port that exhausts dust backward from the first exhaust port. A dust fan is provided, a second dust outlet is formed on a side plate opposite to the handling port, and a second dust fan that discharges dust above the swinging sorting plate from the second dust outlet, The second processing cylinder is provided so as to rotate integrally with the second processing cylinder behind the second processing cylinder.

A feature of the invention according to claim 2 is that, at the rear half of the handling room, on the lateral outer upper side opposite to the handling port, the processed material reaching the latter half of the handling room is received and reprocessed. First
A processing cylinder and a first net for leak-selecting the reprocessed material on a swinging separation plate are provided along the handling cylinder, and a first half of the handling chamber is provided.
A second processing cylinder that receives and processes the second processed material from the second reduction device on the lateral outer side opposite to the handling port, and that the second processed material is subjected to leakage sorting on a swing sorting plate. A second receiving net is provided along the handling cylinder at a position lower than the first processing cylinder, and a first dust outlet is formed on the rear end side of the apparatus.
A first dust exhaust fan for exhausting dust backward from the first exhaust port is provided, and a second dust exhaust fan for sending dust above an oscillating sorting plate to the first dust exhaust fan is subjected to the second processing. The second processing cylinder is provided so as to rotate integrally with the second processing cylinder behind the cylinder.

According to the first aspect of the present invention, [a] The processed material that has reached the latter half of the handling chamber enters the first processing cylinder side and is handled and processed, and grains and the like pass through the first receiving net. Leaks onto the oscillating sorting plate via the oscillating sorting plate, and the straw chips and the like exit from the first processing cylinder and the rear end side of the first receiving net. The second processed material from the second reduction device enters the second processing cylinder side and is handled and processed. Grains and the like leak onto the oscillating sorting plate via the second receiving net, and straw waste and the like are removed from the second processing drum side. 2 It exits from the processing cylinder and the rear end side of the second receiving net.

That is, since the processed material on the second half side of the handling room, which contains a large amount of waste chips, is reprocessed by the first processing cylinder and the first receiving net, for example, the rotation speed of the first processing cylinder and the first processing cylinder By setting the processing conditions of the processed material, such as the volume of the processing cylinder and the first receiving net, so as to match the properties of the processed material, the kernels can be easily collected, and the load on the handling cylinder can be reduced. It can be reduced and the processing capacity of the handling cylinder can be increased. And, since the second processed material is handled and processed by the second processing body side and subjected to leakage sorting by the second receiving net, even if it is paddy mixed with straw waste or rice with branches, the grain is reduced to straw waste. It can be easily separated and collected from the branches.

[B] In addition to operating the first dust discharging fan to discharge dust backward from the first dust discharging port on the rear end side of the apparatus, the second dust discharging fan is operated to operate the dust discharging port. Discharges the dust above the swing sorting plate from the second dust outlet formed on the opposite side plate, thereby eliminating the circulation of dust and facilitating the collection of grains. Since the second dust discharge fan is provided so as to rotate integrally with the second processing drum behind the second processing drum, it is not necessary to newly provide a drive unit for the second dust discharge fan, and the cost can be reduced. In addition, the structure can be simplified.

According to the structure of the second aspect, [c] the same action as the above [a] can be obtained, and the following action can be obtained. By operating the second dust fan, the dust above the swinging sorting plate is sent to the first dust fan, and the dust is rearward from the first dust outlet on the rear end side of the apparatus via the first dust fan. Therefore, dust can be efficiently discharged and the kernel can be easily collected. Since the second dust discharge fan is provided so as to rotate integrally with the second processing drum behind the second processing drum, it is not necessary to newly provide a drive unit for the second dust discharge fan, and the cost can be reduced. In addition, the structure can be simplified.

[Effect] Therefore, according to the structure of claim 1,
By the above operations [1] and [2], the sorting accuracy can be increased, the grain recovery rate can be increased, the cost can be reduced, the economy can be improved, and the structure can be made compact.

According to the configuration of claim 2, the above operation (c)
As a result, the sorting accuracy can be increased and the grain recovery rate can be increased, the cost can be reduced, the economy is improved, and the structure can be made compact.
