Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a paddy holder in a self-propelled self-ejection system.

In other words, the paddy tray installed at the rear of the machine can be raised to support the paddy bags in a horizontal state and stored out of the way, or the machine can be tilted to the rear and grounded to load and unload the threshing machine. The structure is designed so that it can be used as a stand to prevent the machine from falling over when changing the loading platform or changing the loading platform. The present invention provides a simple structure that can be easily implemented and can be supported without being exposed.

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

Figure 1 shows a side view of the self-propelled self-escape, with crawler 5
An engine E etc. is installed on the rear side of the machine base 6 supported by the machine base 6, and a handle rod 8 and a control lever 9 etc. are installed on the rear upper part of the cover 7 that covers the engine E etc. The threshing machine F is mounted above the mounting frame 10 installed on the front side of the machine so that it can be loaded and unloaded freely, but when the loading platform G having the guard 11 around it is mounted above the mounting frame 10, it becomes a transport vehicle. Configure.

Further, a grain lifting cylinder 12 is installed so as to extend from the lower part of the entrance side of the threshing machine F to the rear side of the machine body,
Both discharge tubes 13 and 14 are hung from the tip of the grain lifting tube 12, and on both sides of both discharge tubes 13 and 14, paddy receiving rods 16 and 16 capable of suspending a paddy bag 15 are installed from the grain lifting tube 12 side. The device is installed and configured to support the device.

B is a paddy holder that supports the bottom of the paddy bag 15;
The support rod A fixed on the lower surface side of the rice holder B is extended forward, and the base a, which is one end side of the support rod A, is slightly higher in front of the horizontal paddy holder B and extends laterally. A short support rod 1 made of a round bar is fixed to a portion of the base a on the inner end side away from the end in a direction perpendicular to the axial direction of the base a. .

At the end of the machine stand 6 at the side of the rear end of the machine where the rice holder B is attached, a support C formed so that both support plates 17 and 18 protrude at a distance in the lateral direction is fixed. The base a of the support rod A was fitted into both round holes 19 formed corresponding to the support plates 17 and 18 so as to be movable and rotatable in the axial direction, and protruded from the support plate 18 side. A seat plate 20 is fixed to the tip of the base a with bolts and nuts 21, and a compression spring 22 is fitted in the portion of the base a between the support plate 18 and the seat plate 20, and the compression spring 22 causes the support rod 1 to It is configured to be biased so as to be pulled toward the support plate 17 side.

Further, a cam body D is fixed to the outer surface of the support plate 17, which is the outside of the support metal C, and the cam body D is fixed so that the base part a passes through the center of the cam body D formed in a short cylindrical shape. As shown in FIGS. 6 and 7, concave portions 2, 3, and 4 into which the support rod 1 can be fitted are sequentially formed on the edge of the cam body D from the upper side to the lower side, and the rice holder is When the stand B is tilted backwards and is in contact with the ground, the support rod 1 is placed in the recess 2, when the rice holder B is horizontal, the support rod 1 is placed in the recess 3, and when the rice holder B is stored in an upright position, the support rod 1 is stored in the recess 2. The supporting rods 1 are installed in the recesses 4 so that they can be fitted into each of the recesses 4, and the above-mentioned states can be changed by changing the fitting.

Therefore, FIGS. 1 to 4 and 8
As shown in the figure, when the support rod 1 is fitted into the recess 3, the compression spring 22 presses the support rod 1 into the recess 3, and the rice holder B is supported in a horizontal state without any play. The rice is now ready to receive paddy.

When storing the rice holder B, when the rice holder B is lifted upward and rotated around the base a, the support rod 1 comes out from the recess 3 while being pressed against the edge of the cam body D and slides as it is. When the rice holder B stands up, the support rod 1 fits into the recess 4 and changes from the recess 3 to the recess 4.
The state shown in the figure and FIG. 10 is reached, and the compression spring 2
When the support rod 1 is pressed into the recess 4 by 2, the rice holder B stands upright and is stored without wobbling.

Also, when the rice holder B is pushed down from the horizontal state and tilted backward, the support rod 1 fits into the recess 2 and changes from the recess 3 to the recess 2, as shown in Figs. 11 and 12. When the paddy holder B is firmly held, the end of the rice holder B touches the ground and becomes a stand, and is used when loading and unloading the threshing machine F as shown in Fig. 13, or when loading and unloading the loading platform G as shown in Fig. 14. In such a case, the rice holder B can serve as a stand to support the rear part of the machine, which becomes somewhat heavy, so that it does not fall over.

In this way, the present invention allows the base of the support rod extending from the rice holder to be inserted into the support at the rear of the machine so that it can move and rotate freely in the axial direction, and is elastically biased in the axial direction. A support rod is fixed to the base of the support rod on the side, and a cam body is fixed to the side of the support rod that is in pressure contact with the support rod, and the support rod is fitted to the cam body, and the fitting can be changed. Therefore, the paddy holder is configured to be able to be changed to a horizontal state, an upright state, and a grounded state, so that the paddy holder installed at the rear of the machine can be erected to support the paddy bag in a horizontal state, so that it does not get in the way. By tilting the paddy holder towards the rear of the machine and placing it on the ground, it can be used as a stand to prevent the machine from falling over when loading and unloading the threshing machine or changing the loading platform. By fitting the support rod into the recess of the cam body while rotating the stand, it is possible to easily change to each state, and in each state, the support rod is pressed into the recess to prevent rattling. It has the advantage that it can be supported by a simple structure and can be suitably implemented.
