Description

[Detailed description of the invention] The present invention includes a threshing section that introduces the entire amount of reaped stalks and threshes them, a sorting section that collects the grains from the threshed material, and a threshing section that collects the grains from the threshed material. The present invention relates to a conventional combine harvester equipped with a culm processing section that sends out grain to the rear of the machine and leaks grain to the sorting section.

Conventionally, as the culm processing section of the above-mentioned ordinary combine harvester, a rack with a saw-toothed upper edge is arranged so as to move in an elliptical direction in the longitudinal direction of the machine, and the culm fed into the upper part of the rack is moved up and down. The so-called straw walker type is widely used, which transports the grain to the rear of the machine while shaking it, and picks out the grains during the transport, but the culm sent to the culm processing section is generally coarse. The culms are large and large in quantity, and the waste culms are easily fed in layers onto racks and transported as they are, and are ejected from the machine with many grains in them without being sufficiently strained or cracked. It was hot.

The present invention was developed in view of the above circumstances, and improves the recovery efficiency of residual grains such as prickly grains and unshipped grains by simple and rational modification of the culm processing section. Furthermore, the purpose is to make the overall length of the aircraft more compact than that of the straw walker type.

The culm processing section of a conventional combine harvester according to the present invention is provided with a disk equipped with a locking body on the periphery at a distance in the axial direction of the disk with respect to the drive horizontal shaft, and lifts the disk onto the processed material. It is characterized in that it takes a detour route in which it is later lowered, and that treated teeth are provided in the middle of the detour route so as to overlap the disk in side view.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 shows a vertical side view of an ordinary combine harvester, in which a reaping transport section 1 that can freely swing around a horizontal axis is attached to the front side of a traveling machine body 2, and a reaping stem culm is transported from the reaping transport section 1 to the front side of a traveling machine body 2. A threshing section 3 that introduces the entire grain and threshes it; a sorting section 4 that collects grains from the threshed material; The traveling machine body 2 is equipped with a culm processing section 6 that sends the grains to the soil and leaks the grains to the sorting section 4, and furthermore, a control section 7, a grain tank 8, and an engine 9 are arranged. A conventional combine harvester is constructed that harvests and threshes grains, collects grains from the processed material, and discharges the waste culms outside the machine.

The waste culm processing unit 6 includes a straw walker type waste culm processing device 10 that receives the threshed material from the beater 5 and performs a shaking sorting process, and the processing device 10.
and a rotary type waste culm processing device 11 for sorting and processing the processed materials from the rotary type waste culm processing device 11.
As shown in FIG. 2, a drive horizontal shaft 13 that rotates clockwise in the figure is installed between the left and right side plates 12, 12 on the upper rear side of the sorting section 4, and on the drive horizontal shaft 13, Discs 14 equipped with saw-toothed locking bodies a on their peripheries are provided at intervals in the axial direction to allow the culm to take a detour route in which it is raised and later lowered, Then, the disc 14 enters between the adjacent discs 14, 14 and the disc 14 is
The treated teeth 15 that overlap with each other are provided at intervals in the rotational direction of the disk 14 in the middle of the detour route, and
As the disks 14 rotate, the objects to be processed are caused to take a detour by the locking bodies a on the circumference of the disks, and
In the middle of the path, the processing teeth 15 cut the culms that are supported on both sides by the adjacent discs 14, and at the same time give sufficient straining and loosening effects to the material to be processed. The processed material is diffused, thereby effectively separating the grains in the processed material, leaking the grains into the sorting section 4 through the discs 14, and removing them from the culm. will be ejected from the rear of the aircraft.

Since the material to be processed is made to take a detour, that is, to take a long processing path relative to the length of the machine in the longitudinal direction, for example, as shown in Figure 3, the same processing path is used for straw walker processing. Device 1
6, as shown in Figure 1, the overall length of the machine can be made shorter by the dimension L, and the sorting performance can also be improved.In other words, the straw walker type processing device When providing the same sorting performance as No. 16, the overall length of the aircraft can be further shortened.

Note that it is not necessary to arrange the treated teeth 15 in all the discs 14, and it is also possible to provide only one or three or more in the rotational direction of the disc 14.

Further, the front edge of the processed tooth 15 and the rear edge of the locking member a may be formed into a blade edge, or the locking member a may be formed into a pin shape, and the specific structure can be modified in various ways.

Furthermore, although the straw walker type and rotary type treatment devices 10 and 11 constitute the culm treatment section 6, instead of the straw walker type treatment device 10,
It is possible to change to a rotary processing device consisting of a cylinder with processing teeth on the periphery and a concave installed opposite to the lower part of the cylinder, or omit the processing device 10 itself and use only the rotary processing device 11. The discharged culm processing section 6 may be configured, and in this case, a plurality of rotary processing devices 11 may be arranged side by side in the longitudinal direction of the machine body.

As explained above, the conventional combine harvester according to the present invention allows the threshing material to take a detour,
When the length of the waste culm processing path is made equal to the length of the waste culm processing path of the conventional straw walker type, the overall length of the machine can be made much shorter than that of the conventional straw walker type.

In addition, by the action of the disk with a locking body around it and the processing teeth, the culm in the processing material is cut, and the processing material is given sufficient squeezing and loosening action to spread the processing material. The remaining grains in the processed material can be effectively separated and recovered.

Moreover, this diffused processed material falls into the sorting air path from a detour route where it is once raised by the disk equipped with a locking body around it and then lowered.
It is possible to drop a long sorting distance to reach the grain collection section of the processing section, and as a result, the dispersed and easily separated processed material is exposed to sufficient sorting air, and the grains in the processed material are separated. The remaining grains can be separated much more efficiently, making effective sorting possible.

Furthermore, since the culm processing section has a rotating structure, vibration and noise are much smaller than those of the straw walker type, and the durability of the parts can be improved. Through simple and rational modification of the formula, we have been able to achieve various effects.
