Description

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.
The first processing chamber is formed by providing the receiving net along the handling cylinder,
In the first half of the handling room, on the lateral outer side opposite to the handling port, 2
A second processing cylinder for receiving and handling the second processed material from the second reduction device, and a second receiving net for leak-selecting the second processed material on a swinging separation plate in a state along the processing cylinder. Forming a second processing chamber, and providing a partition wall for partitioning a space extending from the first processing chamber to the second half of the handling chamber and a space extending from the second processing chamber to the first half of the handling chamber. The partition wall supports the front end of the rotating shaft of the first processing cylinder, the rear end of the rotating shaft of the second processing cylinder, and the front and rear intermediate portion of the main receiving net stretched to face the handling cylinder. It is in that.

A feature of the invention according to claim 2 is that, in the invention according to claim 1, the main receiving net is formed into a divided structure of a front receiving net on the front side of the partition wall and a rear receiving net on the rear side. In addition, a peripheral edge of the partition wall around the handling cylinder extends from between the front receiving net and the rear receiving net toward the handling cylinder center side of the two receiving nets.

According to the first aspect of the present invention, the processed material reaching the second half of the handling chamber enters the first processing cylinder side and is handled and processed, and grains and the like are shaken through the first receiving net. Leakage etc. leaks onto the moving 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.

Further, since a partition wall is provided for partitioning a space extending from the first processing chamber to the second half of the handling chamber and a space extending from the second processing chamber to the first half of the handling chamber, the partition wall is formed of a support frame. And the structure of the device is strengthened.

[0010] In the threshing apparatus, since a processed material is put between the handling cylinder and the main receiving net for handling, a force directed radially outward of the handling cylinder is applied to the main receiving net. According to the configuration, since the front and rear intermediate portions of the main receiving net stretched to face the handling cylinder are supported by the partition wall, even if the above-described force is applied to the main receiving net, the main receiving net remains in the above-described manner. It becomes difficult to bulge outward in the radial direction, and it is possible to prevent a decrease in the particle-dropping performance due to an increase in the distance between the main receiving net and the handling cylinder.

And a front end of a rotation shaft of the first processing cylinder;
Since the rear end of the rotation shaft of the second processing cylinder is supported by the partition wall, it is not necessary to separately provide the support members of the first and second processing cylinders.

According to the second aspect of the invention, in addition to the effect similar to the operation of the first aspect, the peripheral edge of the partition wall around the handle cylinder is connected to the front receiving mesh and the rear receiving mesh. Since the processing object extends from the net to the center of the handling cylinder with respect to both receiving nets, the processed material easily crosses the peripheral edge during the conveyance and is easily turned over. As a result, the peripheral portion can exhibit the same function as the bow metal, and can perform the handling operation evenly.

[Effects] Therefore, according to the configuration of the first aspect, it is possible to increase the sorting accuracy and the grain recovery rate. In addition, since the structure of the device is strengthened, durability can be improved, and generation of vibration and noise can be suppressed.
Since the front end of the rotation shaft of the first processing cylinder and the rear end of the rotation shaft of the second processing cylinder are supported by the partition wall, it is not necessary to separately provide the support members for the first and second processing cylinders. Therefore, the structure could be made compact.

According to the structure of the second aspect, in addition to the same effect as the effect of the above-mentioned first aspect, in addition to the fact that the processed object gets over the peripheral edge of the partition wall around the handling cylinder during the transportation. In this case, it is easy to be turned over at that time, and the peripheral portion can perform the same function as the bow metal, so that the handling action can be performed evenly, so that the grain recovery rate can be further increased.
