Description

[Detailed description of the invention] [Industrial application field] The present invention is a threshing machine in which a grain pan and a straw rack are attached to a swinging frame so that the processed material from a handling room is sorted while swinging. This invention relates to an oscillating sorting device.

[Prior Art] In such a swinging sorting device for a threshing machine, in order to improve the efficiency of sorting, it is important to change the sorting form depending on the amount of material to be processed from the handling chamber. Conventionally, the treated material is dropped and supplied from the receiving net under the receiving net stretched below the handling room and above the grain pan to the grain pan side and the straw rack side. It is well known that a processing material diverting member for distributing and supplying the processing material is provided, and the processing material diverting member is configured to be able to swing up and down about a horizontal axis located at the front end thereof.

[Problem that the invention attempts to solve]

When using the above-mentioned conventional device, when the amount of processed material is large, the processing material distribution member is oscillated horizontally or almost horizontally, thereby improving the transfer performance of the processing material by swinging and reducing efficiency. If it is possible to prevent the processing material from accumulating in the processing material distribution member, which is a contributing factor, and the amount of processing material is small, the processing material distribution member is swung to a tilted position with its rear end positioned higher. By doing so, the oscillating feed in the process material diverting member is performed as slowly as possible within the range that does not cause accumulation of the process material in the process material diverting member, and the sorting in the process material diverting member is ensured. This is done to prevent broken pieces from getting into the first product, which is one of the causes of reduced efficiency.

However, in the conventional structure, when the swinging frame swing locus, that is, the stroke rack locus is set to be inverted, when the amount of material to be processed is large,
It is not possible to strongly shake the processed material up and down in the straw rack, and the separation of grains from foreign substances such as broken straw is poor, resulting in a large amount of grains being easily released along with foreign substances, resulting in a decrease in collection efficiency. And, on the contrary,
If the rocking trajectory is set upright, when the amount of material to be processed is small, the material to be processed will be shaken too strongly in the stroke rack, and a large amount of foreign matter will be collected together with the grains, resulting in a decrease in efficiency. was inviting.

The present invention has been developed in view of the above-mentioned circumstances, and even if the attitude of the material diverting member and the swing trajectory of the swing sorting device are changed according to the amount of material to be processed, the collection efficiency of the material to be processed can be improved. The purpose of the present invention is to provide a swinging sorting device for a threshing machine that can perform

[Means for solving problems]

In order to achieve the above object, the oscillating sorting device for a threshing machine according to the present invention has the above-mentioned structure, and is provided with A processing material distribution member is disposed for distributing the processing material falling and supplied from the receiving net side to the grain pan side and the stroller rack side, and the processing material distribution member is connected to a horizontal axis located at the front end side of the processing material distribution member. The swing frame is configured to be able to swing up and down around a core, and the swing frame is provided with an undulation degree changing mechanism that can change the undulation degree of a swing locus of the swing frame, and further, the undulation degree change mechanism and a linking mechanism linked to the processing material diverting member so that the swing locus is reversibly changed to the collapsed side in conjunction with the upward swinging of the processing material diverting member. is the feature configuration.

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

[Effect]

In other words, not only is the processing material diverting member swingable so as to change its attitude, but also the degree of undulation of the swing trajectory of the swing sorting device can be changed in conjunction with this attitude change, so there is less material to be processed. In this case, as shown in Fig. 4A, the material diverting member should be swung to a steeply inclined position with the rear end side located higher, and the swing trajectory of the oscillating sorting device should be lowered. Therefore, the material to be processed is oscillated as slowly as possible within the range that does not cause stagnation of the material to be processed in the material to be processed, so that the material to be processed can be reliably sorted. Moreover, in the case of a stroke rack, excessive shaking of the processed material up and down can be eliminated, thereby reducing the amount of contaminants such as cut straws included in the second collection. On the other hand, when there is a large amount of material to be processed, the material to be processed can be diverted by swinging the material diverting member into a laid-down position and raising the swing locus of the swing sorting device, as shown in Figure 4B. The member prevents the processed material from stagnation in the processed material distribution member, and the stroke rack strongly shakes the processed material up and down to improve the separation of grains from impurities. It is possible to reduce grain loss that would otherwise be released along with impurities. Moreover, since the change in the attitude of the processing material diverting member and the change in the swing locus of the swing sorting device are linked, only one switching operation is required.

[Effect of idea]

Therefore, the present invention not only improves efficiency by preventing the accumulation of processed materials in the processed material distribution member and improving the sorting performance of the processed material distribution member, but also reduces grain loss and eliminates foreign matter in the secondary material. By reducing the proportion of mixed materials, the sorting efficiency can be significantly improved, and moreover, it has become possible to design an efficient sorting section with good operability according to the amount of material to be processed.
