Description

[Detailed explanation of the idea] The present invention relates to a paddy receiving and discharging device in a combine harvester.

In other words, it is possible to receive paddy in a box-shaped tank without having to do the complicated paddy receiving work of changing paddy bags as in the past, and when taking out paddy, the paddy can be removed from a high position relative to a paddy transport vehicle, etc. To provide a rice-hulling machine which can be properly and conveniently discharged, and which can be suitably carried out by keeping the rice-discharging tube in a stored state so that it does not protrude to the side of the machine body during rice-receiving work.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of the combine harvester. At the front left side of the machine body supported by a track-type traveling body 1, there is a weeding body 2° and a raising body 3.
Cutting blade 4. A reaping conveyance device C having a conveyor 5 etc. is installed,
A threshing device T having a foot chain 6, etc. is installed at the rear of the device C, and a control unit 10 having a control platform 8, a seat 9, etc. is installed on the front side of the machine body on the right side of the reaping and conveying device C. An engine section 11 is installed and configured behind it.

A box-shaped paddy tank A is installed on the machine stand 12 which is buttoned behind the engine part 11, and the machine stand 12 is installed at an interval in the lateral direction.
The middle and both sides of the paddy tank A are freely rotatably attached to the upper parts of both supports 13 and 13' erected on the top of the support shafts 14 and 14'. are installed so that they are positioned above the machine stand 12 with a certain distance between them, one end of the hydraulic cylinder 16 is connected to the lower part of the support column 13 by a pin 1T, and the other end of the piston rod 16' extends from inside the hydraulic cylinder 16. is connected to the side of the paddy tank A via a pin 18, communicates with the No. 1 conveyor of the threshing device γ, extends upwardly a grain lifting cylinder 19 equipped with a spiral conveyor, and has an outlet at its upper end. 19' is configured to communicate with the upper end of the paddy tank A with some play.

A gutter 20 is formed inside the lower part of the paddy tank A, and a spiral conveyor 21 is installed in the gutter 20 in a direction perpendicular to the support shafts 14 and 14'. The helical conveyor 21 is rotated by a hydraulic motor 22 installed in the paddy tank A, and the end of the helical conveyor 21 is exposed to the paddy outlet 23 provided at the rear lower part of the paddy tank A. The assembly 24 is attached and configured.

One end of a long paddy discharge pipe 25 can be joined to the paddy discharge port 23, and the paddy discharge pipe 25 and the paddy discharge port 23
A hinge 26 is interposed across the upper part of the end, and the paddy discharge pipe 2
5 is connected to the paddy outlet 23 so as to be bendable, and the long paddy discharge tube 25 has an outlet 2 with an opening/closing lid 27 at its tip.
8, and a spiral conveyor 29 is installed in the paddy discharge pipe 25, and the end of the spiral conveyor 29 facing one end of the paddy discharge pipe 25 can be removably engaged with the meshing engaging body 24. A meshing engagement body 30 is attached, and an opening/closing plug 31 is detachably attached to the paddy outlet 23.

32 is a housing of a straw cutter connected to the rear of the threshing device 7, a guide ring 33 is rotatably mounted on the side of the housing 32, and the discharge pipe 25 is slidably mounted on the guide ring 33. However, the guide ring 33 is installed so as to be positioned obliquely upwardly relative to the bottom 15 of the paddy tank A.

Therefore, during combine harvester work, as shown in Figures 1 to 3, the bottom part of the paddy tank A must be fixed without rotating.
Insert the opening/closing valve 31 into the outlet 23 so that the valve 5 is in the water state.
When installed, the paddy discharge tube 25 connected by the hinge 26 is supported by the guide ring 33 and is in an inclined state, and is bent relative to the paddy outlet 23 and protrudes to the rear of the lower part of the machine and becomes a nuisance. The paddy is lifted up by the grain lifting cylinder 19 and put into the paddy tank A from the outlet 19'.

When the paddy tank A is full of paddy, remove the on-off valve 31 from the paddy outlet 23 and hydraulically operate the hydraulic cylinder 16 to stop the combine harvester operation, and the paddy tank A is moved to the spindle 1.
4 and 14', the side of the paddy outlet 23 is raised, and the paddy discharge pipe 25 connected by the hinge 26 is pushed up and changes its inclination state, and the guide ring 3
Slide to 3.

When the axes of both spiral conveyors 21 and 29 coincide, the meshing engaging body 2430 engages as shown in the button in FIG. 4 and in FIG. The outlet 28 is raised to a suitable height to allow the paddy to be discharged to the paddy transport vehicle.

In this state, when the opening/closing lid 27 is removed and the hydraulic motor 22 is operated, both spiral conveyors 21 and 29 rotate, and the paddy in the paddy tank A passes through the discharge tube 25 and is discharged from the outlet 28.

In this way, the present invention has a box-shaped paddy tank that can be loaded with paddy from above, is rotatable around a spindle, and is mounted on the machine body, and a spiral conveyor 21 is installed inside the tank at the bottom to transport the paddy. The terminal end is exposed to the paddy outlet provided at the rear lower part of the paddy tank, and a paddy discharge tube that can be bent and stored is connected to the paddy outlet, and a paddy discharge tube is connected to the spiral conveyor inside the paddy discharge tube. It is constructed by accommodating a connecting spiral conveyor 29, and when the paddy tank rotates around the spindle and the paddy outlet side rises, the outlet of the paddy discharge tube is pushed up to an upper position outside the machine body. Because of this structure, it is possible to receive paddy in a box-shaped paddy tank without having to do the complicated paddy receiving work of changing paddy bags as in the past, and when taking out the paddy, the paddy tank can be rotated and the paddy discharge pipe can be opened. By extending it high, it is possible to conveniently discharge paddy from a high position, for example, from a paddy transport vehicle, etc., and the paddy discharge tube can be bent toward the paddy tank side for combine harvester work when receiving paddy or when driving on the road. It has a feature that it can be conveniently carried out in a stored state so that the discharge tube does not protrude outward.
