Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a reaping and harvesting machine typified by a combine harvester and the like.

[Conventional technology]

Conventionally, in this type of reaping and harvesting machine, in order to improve the threshing efficiency, processing chambers were installed side by side on the side of the processing chamber, and the second reductant was returned to the processing chamber, and the processing chamber was processed in the processing chamber. The second part was processed in the cylinder (see Japanese Utility Model Application No. 57-197837).

[Problem that the invention seeks to solve]

However, in this case, due to the equipment configuration, the second material must be transported from the exit of the second material conveying device located at the lowest end of the threshing section to the processing chamber located at the top end of the threshing section, and the lifting height As the flow rate increases, the capacity of the thrower as a secondary object conveying device becomes inevitably large, and the conveyance path to the processing chamber becomes longer, so there is a risk that the conveyed objects may accumulate at bends. It was hot too.

In view of the above-mentioned circumstances, the present invention adds a new mechanism to the thrower tube for reducing the second material, and even with a small thrower capacity, it is possible to sufficiently reduce the second material. The purpose of the present invention is to provide a reaping/harvesting machine that can reduce the installation space for the equipment and its drive structure required for reprocessing.

[Means for solving problems]

In order to achieve the above object, the reaping and harvesting machine according to the present invention is provided with a processing rotating body for the second material in the middle of the thrower tube for returning the second material to the swing sorting section, and a dust cleaning port in the handling chamber. A driving rotary body is provided which applies a decomposition effect to the processed material supplied from the feed chain, the rotating shafts of both rotary bodies are integrated, and the position of the driving rotary body is set below the feed chain, and The processing rotating body is characterized in that processing teeth arranged at intervals in a direction intersecting the direction of transport of the second reduced product are implanted on the outer peripheral surface.

The functions and effects of this characteristic configuration are as follows.

[Effect]

In other words, the processing teeth installed on the outer circumferential surface of the processing rotor and the inner circumferential surface of the thrower cylinder can apply a fir treatment action to the second reduction product, thereby performing a single grain treatment. be able to. This results in
Unlike the conventional method, a processing cylinder is not required, and the second reduced product can be reprocessed by the processing rotor and then returned to the swinging sorting device, so that the lift by the thrower can be lowered.

In addition, since the rotation axes of the processing rotor and the drive rotor are integrated, and the driving force for the processing rotor can be actively obtained from the drive rotor, the transmission structure for the processing rotor can be reduced. It can also be used as a transmission structure for the drive rotor, and since the treatment rotor is actively driven, the secondary reduction product is also prevented from clogging the treatment rotor.

Furthermore, the waste straw and other processed materials discharged from the rear of the handling chamber are actively given a loosening action by the driving rotary body to loosen the entanglements between the waste straw and make the waste straw inside the waste straw. This makes it easier to collect the paddy with a swinging sorter.

〔Effect of the invention〕

Therefore, while being reprocessed by the driven processing rotary body, an active transfer force is applied to the second reduced product and it can be returned to the oscillating sorting section, so the transfer force for the second reduced product at the thrower is It can be small, the thrower capacity can be reduced, and the second reduction product can be transferred without clogging, and by providing a processing rotor, the processing chamber can be virtually omitted, and the drive rotor and processing rotor can be separated. Since the drive structure is shared, the threshing device as a whole can be made smaller.

〔Example〕

The second material processing structure will be explained using a combine harvester as an example of a reaping/harvesting machine.

As shown in FIGS. 3 and 4, a reaping preprocessing section 1 and a control section 2 are installed side by side at the front of the machine, and a feed chain 3 and a handling barrel 4 are provided at the rear of the reaping preprocessing section 1. A threshing section 5 is provided, and this threshing section 5
A swinging sorting section 7 is provided below which performs wind selection using the sorting wind from the winnowing machine 6, and this swinging sorting section 7
A combine harvester is constructed by providing a first material conveying device 9 for transporting shell grains from shells to a shell grain tank 8 and a second material conveying device 10 for returning second grains from the swinging sorting section 7 to the swinging sorting section 7. It has been done.

The second object processing structure will be explained. A thrower 11 for flipping up the second item is provided at the end of the conveyance of the screw conveyor type second item conveying device 10, and
A thrower cylinder 12 is provided to guide the secondary material thrown up by the thrower 11 back into the grain pan 7A of the swing sorting section 7. As shown in FIG.
and a horizontal position part 12B to the swinging sorting part 7,
The processing rotating body 13 is installed in the vertical position part 12A, the horizontal position part 12B, and the bending part. As shown in FIG. 2, the rotary body 13 has a treated tooth 14 formed by alternately implanting rod-type treated teeth 14b and blade-like treated teeth 14a on the body of the rotary body,
Rod-shaped receiving teeth 15 are provided on the inner surface of the thrower cylinder 12 and are located between the cutout portion of the blade-shaped processed teeth 14a and the rod-shaped processed teeth 14b.
It has a structure that adds a powerful processing effect. Incidentally, the tip locus of the treated tooth 14 is made to overlap the receiving tooth 15 in a side view. Also, the rotation speed of the thrower 11 is 1200 rpm (circumferential speed 20 m/s), while the rotation speed at the processing rotation end is 800 rpm (circumferential speed
8m/s). The treated tooth 14 is a second tooth.
As shown in the figure, it may be only a rod-shaped type.
The gap between the tip locus of the treated teeth 14 and the inner circumferential surface of the thrower cylinder 12 is kept at 4 to 7 mm.

Further, the processing rotary body 13 is connected to the dust cleaning port 1 of the handling chamber 16.
It is formed at the tip of the drive rotating body 17 provided corresponding to the rotating shaft 13A, 1
Along with 7A, the processing rotor 13 and the drive rotor 17
The rotary drums themselves as the rotor bodies constituting each are also integrally fixed, allowing a common driving source.
On the other hand, the driving rotary body 17 functions to improve the sorting performance in the swing sorting section 7 by adding a loosening effect to the waste straw discharged from the dust-sweeping port 16A.

As shown in FIG. 1, the storage portion 12C of the thrower cylinder 12 relative to the processing rotary body 13 is provided with a bulging portion 12a in which a part of the inner circumferential surface on the discharge locus side of the thrower 11 bulges outward. The processing rotary body 13 is installed and configured such that the processing tooth tip locus of the processing rotary body 13 is located within this bulged portion 12a. Therefore, the thrower cylinder 1 corresponds to the direction of rotation of the thrower 11.
By arranging the distal end locus of the processing tooth 14 to face the inside of the bulged portion 12a with respect to the second article being fed along the inner circumferential surface of the second article, the processing tooth 14 and the second article conveyance locus can be made to overlap. Therefore, the processing action of the processing teeth 14 can be effectively utilized.

[Another example]

(a) As shown in FIG. 5, instead of the receiving teeth 15, the inner circumferential surface of the thrower cylinder 12 is formed into a rough surface 12b with unevenness, and together with the treated teeth 14, a kneading action is applied to the second material. Good too.

(B) As shown in Figure 6 A and B, together with the receiving tooth 15 and the processing tooth 14, they are made into a long plate shape in the direction of conveyance of the second material, so that the kneading action section by both 15 and 14 can be long. It is also good to have a configuration that does this. The receiving tooth 15 may have any length as long as it can perform a processing action simultaneously with a plurality of processing teeth 14.

(c) A plurality of treated teeth 14 may be attached to an L-shaped base 18 and formed integrally.

(d) As a means for integrating the rotating shaft 13A of the processing rotating body 13 and the rotating shaft 17A of the driving rotating body 17,
As shown in FIG. 8A, the shaft may be used in common, or it may be integrated with a coupling 19 as shown in B, and a universal joint 20 as shown in C.

(e) The above embodiments may be applied to reaping and harvesting machines other than combines.
