Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a diffuser plate in a screw-type handling cylinder.

(Prior Art) The diffusion plate in a conventional screw-type handling cylinder is fixed to the screw.

(Problems to be Solved by the Invention) As described above, with the diffuser plate fixed to the screw, there were problems such as deformation of the diffuser plate, and this was improved by making it a rotating type.

However, when crops such as soybeans and buckwheat are grown at low rotation speeds, and when the flow rate is high, problems arise in terms of effectiveness.

(Means for solving the problem) Therefore, the technical problem of this proposal is to provide a screw type handling cylinder that can exhibit the effect of the diffuser plate even when the rotation is low. The technical means of the present invention to solve this problem is to install the diffuser plate in the axial direction between the pitches of the screws in the handling cylinder so that it is rotatable with respect to the handling cylinder, and to make the tip heavy. A space is provided between the diffuser plate and the diffuser plate.

(Example) The following description will be made based on the embodiments shown in the drawings.

First, the entire screw-thresher will be explained.

In Fig. 6, the crops are raked by a raking reel 1 and cut by a cutting blade 2, and the cut crops are transported from a raking auger 3 to a handling room 6 by a chain conveyor 5 in a feeder house 4, where they are handled in a screw-type manner. The grain is threshed in barrel 7.

The threshed grains fall from the receiving net 8 onto the oscillating sorting board 9 and are sorted.

The threshed grains are sorted on this swing sorting board 9, but only the long straw is carried towards the rear dust outlet.
In addition, the materials to be sorted on the swing sorting board 9 are sorted by the sorting air from the winnowing machine 11 or the sorting air from the blower fan 12, and grains are sent to the first gutter 13 and second items to the second gutter 1
4 and the grains that have fallen first into the gutter 13 are conveyed to a paddy tank (not shown) via a grain lifting cylinder 16.

The second material is returned to the oscillating sorting board 9 through the thrower cylinder 18.

In this case, the diffusion plate 22 provided between the screws 20 in the screw threshing machine as described above is the 7th and 8th.
As shown in the figure, it was fixed to the screw 20 of the handling cylinder 7, but since there was a problem of deformation, a rotating type as shown in Fig. 9 was adopted. However, even the rotating type could not fully demonstrate its performance as a diffuser when the rotation was low.

Therefore, in the present invention, as shown in FIGS. 1, 2, and 3, the diffuser plate 22 is rotatable by engaging its rolled-in portion 21 with a receiving metal fitting 23 fixed to the handling barrel 7 with bolts and nuts. Attach a weight 24 to the tip,
The tip was made to be aggressively heavy.

Instead of the weight, the diffuser plate 22 itself can be formed into a fan shape that widens toward the tip as shown in FIG. 4, so that the tip becomes heavier. The tip may be bent or curved toward the lower side in the rotational direction, as shown in C, so that the tip becomes heavier.

By configuring the distal end to be heavy as described above, the diffusing plate 22 can stand up due to centrifugal force even when the rotation of the handling cylinder is low, and can fully perform its function as a diffusing plate.

Thus, a distance a was provided between the screw 20 and the diffuser plate 22. As a result, the grain culm can be taken in well, and the feeding action during the feeding action can be carried out reliably.

(Effect of the invention) According to this technical means, the diffuser plate is rotatable, and its tip is made heavy with a weight, so even when the rotation of the handling cylinder is low, the diffuser plate is rotated by centrifugal force. It stands up, and therefore can exhibit its effect as a diffuser.

Moreover, even at high flow rates, it acts sufficiently on the grain culm, does not change its performance as a diffuser plate, and has the characteristics of stable performance as a threshing machine.

Since there is a space between the screw and the diffuser plate, grain culms can be taken in easily and the feeding action can be performed reliably.
