Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paddy storage and discharge device in a combine harvester.

In other words, when working with a combine harvester, paddy can be received in a paddy bag as before, or the paddy can be continued to be stored in the paddy tank, or the paddy in the paddy tank can be transferred to a transport vehicle using a hoisting tube. It is possible to discharge rice grains, perform suitable unhusking work depending on the working conditions, and provide a simple structure so that it can be carried out suitably.

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

FIG. 1 shows a side view of the combine harvester, with a reaping section C at the front of the machine body supported by both crawlers 11,
A threshing section B is installed at the rear of the machine, and a control column 13 and a seat 14 are installed upright before and after the step 12 installed at the front of one side of the machine, and a paddy-threshing section installed at the rear lower part of the seat 14 is installed. An auxiliary paddy holder 16 is provided on the outer side of the pedestal 15, and an engine part 17 is installed behind the paddy holder 15, so that the structure is similar to the conventional structure.

A paddy tank A is installed above the paddy holder 15, and a switching shutter 18 is installed below the paddy tank A.
A paddy outlet 2 and a falling gutter 3 are installed vertically, an outlet shutter 19 is interposed at the paddy outlet 2, and both paddy receiving rods 20 on both sides of the paddy outlet 2 are capable of suspending the paddy bag 1. A spiral conveyor gutter 5 with the No. 1 spiral conveyor 4 extending from the threshing section B is installed above the end side of the paddy receiving stand 15, and a spiral conveyor gutter 5 is installed in the middle of the spiral conveyor gutter 5. The lower end portions of the drop gutter 3 are configured to communicate with each other.

A cylindrical portion 21 that serves as an outlet is provided protrudingly provided on the side of the terminal end of the spiral conveyor gutter 5, and a cylindrical portion that serves as an inlet is provided on the lower side of the grain-lifting cylinder 7 that houses the spiral conveyor 6 driven by the motor M. 22 is provided in a protruding manner, and both the cylindrical parts 21 and 22 are fitted together freely so that the grain lifting cylinder 7 can be rotated from the side of the paddy tank A to the outside of the machine body using the fitting center as a fulcrum O. Install and configure.

In addition, a threaded rod 25 with a handle 24 is axially locked to the support 23 connected to the middle side of the grain lifting cylinder 7, but is rotatably inserted into the support metal 23, and the screw rod 25 is fitted on the side of the paddy tank A. A threaded rod 25 is screwed into a female threaded body 26 rotatably protruding from the top of the grain lifting cylinder 7, and a discharge vane 2 is installed at the bottom of a discharge gutter 27 connected to the upper part of the grain lifting cylinder 7.
A discharge port 8 is formed through which the paddy discharged by 8 flows out, a cap 29 is provided protruding from the outer periphery of the discharge port 8, and a cap 29 is provided in the upper part of the paddy tank A to match the discharge port 8. While forming the receiving port 9,
The upper surface 10 of the receiving port 9 is formed into a slope in the direction of rotation of the base 29 which rotates around the fulcrum O.

In addition, in the figure, D indicates a transport vehicle.

Therefore, when paddy is received using the paddy bag 1 during combine harvesting operation, the upper discharge port 8 of the hoisting barrel 7 is aligned with the receiving port 9 above the paddy tank A, and the switching shutter 18 is used to remove the paddy from the dropping gutter 3. When the side is closed and the outlet shutter 19 is opened, the paddy lifted into the paddy tank A from the grain lifting tube 7 is discharged from the paddy outlet 2 into the paddy bag 1 suspended from the paddy receiving rods 20, 20, and the paddy is received. This means that you will be able to do this.

In addition, when performing combine harvesting work while storing paddy in the paddy tank A, the switching shutter 1
If the falling gutter 3 and the paddy outlet 2 are closed by the 8, 18 and the outlet shutter 19, the paddy lifted up from the grain lifting cylinder 7 can be stored in the paddy tank A while being put into the paddy tank A.

When transferring the paddy that has accumulated in the paddy tank A to the transport vehicle D in this way, the transport vehicle D is brought close to the paddy tank A side, and the screw rod 25 is rotated by the handle 24. 25 and female thread body 2
6, the grain lifting cylinder 7 is rotated outward about the fulcrum O, and as shown in FIG.
When the switching shutter 18 is operated to open the paddy tank A to the drop gutter 3 side, the paddy in the paddy tank A falls from the drop gutter 3 to the spiral conveyor gutter 5 and is lifted. The grains are lifted up by the barrel 7 and discharged from the discharge port 8 into the loading platform of the transport vehicle D as shown by arrow A.

In addition, when the grain lifting cylinder 7 is rotated around the fulcrum O to communicate with the paddy tank A or rotated outward, the nozzle 29 on the discharge port 8 side is rotated around the fulcrum O as shown by the arrow B. Even if it is rotated around the center, since the upper surface 10 is a slope, it can be rotated so that it is aligned with the receiving port 9 side, or so that it is separated from the receiving port 9 side.

In this way, the present invention has a paddy outlet for receiving paddy in a paddy bag and a falling gutter that are vertically installed at the bottom of the paddy tank installed in the machine, and a drop gutter that extends from the threshing section.
The lower end side of the falling gutter is connected in the middle of the spiral conveyor gutter, and the grain lifting tube inside the spiral conveyor, which communicates with the terminal end of the spiral conveyor gutter, is connected to the side of the paddy tank with its lower part as a fulcrum. The paddy tank is pivoted so that it can rotate from the side toward the outside of the machine, and the upper part of the paddy tank is formed with a receiving port that can match with the upper end side discharge port of the grain lifting cylinder. It is possible to receive paddy in a bag, carry out work while keeping paddy stored in the paddy tank, and discharge the paddy in the paddy tank to a transport vehicle etc. using a hoisting cylinder, so that the working condition can be maintained. It is possible to carry out suitable unhulling work according to the situation, the changeover can be easily carried out by rotating the grain lifting cylinder, and it has the advantage that it can be carried out suitably with a simple structure.
