Explaining the partial supply configuration, the opening (18) provided above the end of the processing case (11) faces the front side where the leakage from the receiving net (30) is severe, and the popping blade ( 19) is arranged so that the unprocessed goods flow in directly above, and the reduced products inherited in the frontal part (29) of the processing section (32) and the unprocessed goods merge in the rear trunk section (28), As described above, the branch stem removal is performed in advance by the impact caused by the release action of the jumping blade (19), and moreover, the phenomenon occurs on the starting end side of the rocking sorting body (3), which shifts to the right side of the handling item. The second processing device is dispersible by the discharge action in the axial direction.

The tooth bar (1) forming the processing cylinder (2)
In 2), a steel plate is punched and bent into a U shape, and a flat portion (67) is inserted with a bolt (68) and is detachably fastened to a mounting plate (60). A discharge port (15) opened to a rear wall (16) while a receiving tooth (17) overlapping with a tooth tip of the rotating tooth bar (12) is erected and erected below the sequence processing case (11). This is a second processing apparatus in which a plurality of adjusting plates (63) for transferring the processed material are obliquely installed on the bulging portion of the processing case (11) to adjust the discharge speed.

FIG. 3 is a perspective view of the processing section, and discharges in the direction of the arrow (c) to the jumping blades (19) fixed to the outer periphery of the rear body section (28) constituting the processing section (32). A lead angle is provided, and the processing object moved from the processing cylinder (2) is made to have the same height as the tooth bar (12) to form a discharge structure with an increased peripheral speed,
The oscillating sorting body (3) is discharged to the starting end side in the axial flow direction and diffused. Further, the processing cylinder (2) sandwiched between the conical frontal head (29) and the rear trunk (28) has a structure in which tooth bars (12) are fastened to a mounting plate (60) radially fixed. , L-shaped air spaces are formed between the attachment plates (60) and (60) reaching the processing body shaft (56) which is the shaft core, and the reduced product freely moves in and out to reduce the grain density. As a result, it is configured to prevent clogging and generation of damaged particles due to compression.

In front of the processing section (32), a conical frontal head (29) has a take-in blade (1) having a lead angle in the grain feeding direction.
4) is fixed, and the end portion of the intake blade (14) is connected to the tooth bar (12) which is planted at the tip of the processing cylinder (2) that is connected continuously. In order to effectively perform initial shredding, the tooth bar (1
Induced in 2), the impact of the removal of branch branch is effectively acted to improve the processing performance and smooth the inheritance.

FIG. 4 is a perspective view of the second processing apparatus, and the arrangement of the related receiving net (30) and the swing selecting body (3) will be described. The arc shape and swing of the receiving net (30). A processing device having a processing unit (32) internally provided in a space formed above the sorting body (3), the processing case (1
The open port (18) provided above the terminal end of 1) is arranged so as to approach the lower part of the receiving net (30) so as to facilitate the inflow of the falling stuffs. Since both the reduced product and the handled inflowing products fall and join together immediately above the jumping blades (19), the diffusion effect on the rocking sorting body (3) is further improved.

As described above, the processing case which is orthogonal to the second reducing cylinder is provided so as to face the lower part of the receiving net stretched on the handling cylinder, and the reduced material and a part of the untreated material are oscillated and sorted. Since it is a second processing device that diffuses and supplies it to the device, it has the following effects.

In a thresher that collects unprocessed material and returns it to a swing selection device, a processing cylinder shaft orthogonal to the handling cylinder is attached to the shaft end of the second reduction shaft, and the processing cylinder is fitted. At the same time, the reduction product is inherited on the front side of the starting end side, the discharge port is opened on the end side, and the processed product is discharged in the axial direction and supplied to the starting end side of the sorting unit. In addition to being compact inside the machine, dust generation was prevented by equipping the sorting path that communicates the generated dust with the suction fan.

Since the front part of the processing cylinder, which has the lead-in blades fixed to the front side, and the rear part, which has the jumping blades fixed to the rear side, are integrally formed, the processing part is integrally formed. The reduced product freely entered and exited the space of the processing cylinder generated in the part, and the grain density decreased, and it was possible to prevent clogging and the generation of damaged grains due to compression.

Since the end of the processing section orthogonal to the second reducing cylinder is faced below the receiving net stretched on the handling cylinder and the processed material is discharged to the vicinity of the sorting section opposite to the supply side, the processing path is extended. As a result of the lateral feeding effect, the removal rate of branching veins is improved, and the deviation phenomenon of the rocking sorting body is also mitigated by diffusion, and the sorting accuracy is improved.

An opening is formed above the rear end of the processing case that houses the processing section, and a part of the handling material that drops from the front of the receiving net is introduced and merged with the processing object to diffuse. As a result, the handled food that falls to the front of the catching net will flow directly above the jumping blades and will spread while being hit, which will reduce the rate of branching before mixing and reduce the rate of branching on the upper surface of the rocking sorting body. Evenly supplied, the sorting performance and the processing ability of branch shoots are improved.

Since the front side of the processing section is a drum-shaped frontal head, and the rear side is constituted by a rear trunk section, the take-in and pop-out blades having the lead angle in the axial direction for transferring and discharging are fixedly provided.
Grains in the transfer area did not become stagnant, clogging was reduced, and the discharge power in the axial direction was increased, allowing the particles to diffuse to the opposite direction of the sorting width to be supplied.

A jumping blade is provided at the rear of the processing cylinder in which the tooth bar is planted and is provided opposite to the discharge port for discharging in the axial direction, so that the flow in the processing cylinder is promoted and clogging in the processing case is prevented. In addition, since the process from the succession to the discharge is in the axial flow direction, the processing action is performed over the entire length, and the removal rate of the branch canal is improved even with the downsized processing device.
