Description

[Detailed description of the invention] Conventionally, when storing a harvester or harvesting different varieties of seed rice, grains were left in the handling room or sorting section of the threshing device at the same time as removing straw, dust, etc. It is necessary to thoroughly clean the machine because it causes rodent damage and causes cross-breeding, but since there are many complex devices inside the machine, it is extremely difficult to clean the machine and thoroughly remove the remaining grains. Ta.

The present invention attempts to solve the above-mentioned problems by using the motive force of the thrower attached as a grain discharge device of a harvesting machine. A harvester is equipped with a grain tank for storing grains lifted by a grain lifting machine of a threshing device, and a thrower is attached to the grain tank as a grain discharge device. This device is characterized in that the base of a connecting cylinder whose tip end is tapered so as to restrict the airflow is removably attached so as to communicate with it, and a cleaning hose is connected in communication with the tip of the connecting cylinder.

Hereinafter, an example of a combine harvester in which the present invention is implemented will be explained with reference to the drawings. 1 is a threshing device mounted on a machine stand 3 having a traveling device 2, and a reaping device and a grain culm conveying device are mounted on the front part of the threshing device. A cutter 5 is installed at the rear, a grain tank 6 is installed at the side of the threshing device 1, an operation panel 7 and a driver's seat 8 are installed at the front, and a cutter 5 is installed at the rear. An engine room 10 is provided.

Further, a transfer spiral 9 is provided in the trough of the V-shaped bottom plate of the grain tank 6, and a grain discharge device consisting of a thrower 11 is attached to the discharge portion thereof.

The thrower 11 is composed of a casing 11b having a discharge tube 11a, and a discharge tube 11c having a curved tip and a base removably connected to the discharge tube 11a.
The discharge tube 11c serves as a lifting portion of the thrower 11.

Reference numeral 12 is a cleaning hose having a nozzle 14 with a tip 13 at its tip, and its base is expanded into a tapered shape as shown in FIG. be.

When reaping and threshing work is performed in the above-mentioned combine harvester, the discharge pipe 11c is connected to the discharge pipe 11a as shown in FIG.
Fill the grain tank 6 with the grains fried by the grain frying machine, and when it is full, drive the machine to the side of the road where the transport vehicle is parked, start the thrower 11, and open the shutter. The grains in the grain tank 6 are carried out and put into the loading platform of the transport vehicle.

In addition, when storing the machine body after harvesting, or when cleaning the outside and inside of the machine body when changing the variety during seed harvesting, remove the discharge tube 11c and remove it as shown in Figures 2 and 3. As shown in FIG.
Fit the base of the discharge cylinder 11a into the discharge cylinder 11a, wrap the band 16, and tighten with the bolt 17 and wing nut 18.

Therefore, when the thrower 11 is rotated by disengaging not only the traveling clutch but also the threshing clutch and the reaping clutch, the blades 11d raise the air and the pressure air discharged from the discharge tube 11a is narrowed by the connecting tube 15. The flow velocity becomes extremely high and it is ejected from the nozzle 14 through the cleaning hose 12, so the pretreatment device 4, the control section and other exposed parts are cleaned, and the covers are removed from the inside of the grain tank 6 and threshing device 1. Blow away accumulated straw waste and scattered grains.

Next, another embodiment will be explained with reference to FIGS. 5 to 8. In this example, the discharge tube 11c of the discharge device attached to the grain tank 6 is divided into an upper tube 11c' and a lower tube 11c'', and these are joined together. The upper tube 11c' is connected by a hinge 19, and during the reaping operation, the upper tube 11c' is folded backwards as shown in FIG. The buckle 21 is placed on the handle 21 and the handle 22 is tightened to tighten the handle 21. In this state, the grain is discharged by holding the handle 22 and tilting it sideways.

Also, when cleaning, the upper cylinder 11c' is placed in the storage position, and the cleaning hose 1 is inserted into the upper end opening of the lower cylinder 11c''.
As shown in FIG. , 24, one hook 24 is hung on the support shaft 19a of the hinge 19, the other hook 24 is placed opposite the buckle 21, and superimposed on the flange 26 of the lower cylinder 11c'' via the rubber packing 25, When the buckle 21 is hooked onto the other hook 24 and tightened, the connecting tube 15 is tightly connected to the upper end opening of the lower tube 11c''.

If the thrower 11 is driven in this state, cleaning similar to that of the previous embodiment can be performed.

In addition, if the harvesting machine is a self-propelled self-propelled threshing machine or a stationary threshing machine, it is desirable to stop the handling cylinder, swing sorting body, etc. for safety reasons.

As described above, the present invention includes a threshing device 1 and a grain tank 6 for storing grains lifted by a grain lifting machine of the threshing device 1 on a machine 3 having a traveling device 2. In a harvesting machine in which the grain tank 6 is equipped with a thrower 11 as a grain discharge device, the thrower 11
The base of a connecting tube 15, which has a tapered tip so as to narrow the blower air flow, is removably attached to the lifting part of the connecting tube 15 so as to communicate with the connecting tube 15, and a cleaning hose 12 is connected to the tip of the connecting tube 15. Therefore, although farmers usually do not have compressors, the blower can be used as a source of wind to reliably blow out straw, dust, grains, etc. in narrow areas that cannot be accessed, and can be used when storing the aircraft or When the variety changes during seed rice harvest,
It is possible to reliably and easily clean every corner of the aircraft body, and it is possible to prevent rodent damage and mixed species.

In addition, the thrower is for lifting grain in the grain tank and is powerful with a high head, and the generated pressure wind is constricted by a connecting tube to increase the flow velocity.
Combined with the fact that the hose is connected to the discharge part of the thrower via the connecting tube to prevent the wind force from weakening, the cleaning hose can provide a powerful blowout of air, making the cleaning process more efficient and efficient. It can be done with precision.

Further, since the connecting tube to which the cleaning hose is connected is attached to and detached from the discharge portion of the thrower, the structure is simple and can be obtained at low cost, and attachment and detachment operations are easy.
