BACKGROUND OF THE INVENTION
The present invention relates to a second processing device for a threshing machine, in which a processing device is provided in a conveyance path for reducing unprocessed materials generated during sorting of shed grained wholesalers, and removes branch-brown adhering grains.
[0002]
[Prior art]
Conventionally, a processing cylinder orthogonal to the cereal cylinders to be carried out to the grain tank is provided, and what is removed immediately before collecting shoots adhering to good grains in the grain tank is described in JP-A-09-084445. The whole amount of grain passes through this processing unit, causing mutual interference and improving the effect of removing the branch, but the grain skin is worn and a large amount of dust is generated. In order to prevent diffusion in the tank, there is a problem that an auxiliary means such as a dust suction fan or a diffusion blade for dispersion is required. Japanese Patent Laid-Open No. 07-143817 discloses a configuration in which a receiving tooth that overlaps with a rotating tooth is erected on a joint portion that conveys the second reduced product, and this is installed detachably. The processing unit is configured so that the reduced product passes through the processing unit and is passed to the second reduction cylinder in one rotation, and the removal rate of the branch limbs is lower than that of the processing unit that performs lateral feed, and the swing sorter The problem remains that the diffusion of is not improved. In the present invention, a processing device is provided in a space formed above the receiving net of the handling chamber and the swing sorting body, and the upper part is opened to partially introduce the handling goods, and the reduced product and the handling goods are joined together. This is the second processing device that effectively removes branch branches while laterally feeding and releases the grains in a wide range in the axial flow direction to facilitate re-sorting.
[0003]

Securing the number of striking strokes and smoothing the transfer part.
【The invention's effect】
As described above, the processing unit orthogonal to the second reduction cylinder is provided, and the handling product and the reduced product are joined together by the processing unit so as to face the swing sorting body, and the swing sorting body is diffused and supplied. Since the second processing apparatus is used, the following effects are exhibited.
[0022]
In the branch-branch processing unit that is connected to the processing unit that is orthogonal to the second reduction cylinder and is mounted above the swinging sorter, the end of the processing case faces the lower side of the receiving net and faces the processing cylinder that is built in. The funnel opening was opened above the processing case, and the branch branch was removed while introducing the handling material and joining with the reduced product. Elimination of branch peduncles due to cereals was promoted, and the adhesion of branch peduncles was removed from both the unprocessed wholesalers and the reduced products.
[0023]
The metal case provided at the tip of the second reduction cylinder is integrated with the processing case to be connected, and is rotatably fitted to the second reduction cylinder, and the open / close cover provided on the outside of the fuselage is opened during maintenance. Since the processing device is turned outside to facilitate the removal operation such as clogging, repair and cleaning can be easily performed.
[0024]
Since the receiving teeth erected in the processing case are arranged so as to face the discharge direction of the cerealing blades provided on the second reduction shaft, it becomes a barrier to the reduced product to be introduced and resistance to the lateral feed speed is generated directly. Untreated splashes reaching the discharge port were prevented, and the number of hits of the tooth bar was increased to improve the treatment effect.
[0025]
Since the intake blades are provided on the head forming the processing unit and the end thereof is connected to the previous tooth bar, the intake grains are guided to the tooth bar while gathering the intake grains, and the initial threshing is effectively performed and received. The splicing performance and processing performance have been improved.
