It is characterized in that engagement recesses 35 and 36 for locking 32 are provided.

<Operation> When the auxiliary floor 19 is swung upward, the pins 37 and 38 slide left and right in the guide grooves 31 and 32. Auxiliary floor 19
When the stand is raised, the pins 37 and 38 are positioned at the corners of the L-shaped guide grooves 31 and 32, and the weight of the support rod 25 causes the pin 3
7,38 slide in the guide grooves 31,32 and are located at the ends of the guide grooves 31,32. In this state, the swing of the auxiliary floor 19 is restricted and fixed in the stored state. Further, the pins 37 and 38 engage with the engaging recesses 35 and 36 provided in the guide grooves 31 and 32, and the mutual movement of the lock plates 29 and 30 and the pins 37 and 38 is restricted, so that they are completely locked. .

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is an overall perspective view of a combine 1 equipped with an embodiment of the present invention. The combine 1 is composed of a main body 3 placed on the traveling device 5, a pretreatment unit 7 and the like supported forward and downward in a swingable manner. The right side of the main body 3 is a storage tank for storing the dehulled paddy. A driver's seat 9 is disposed in front of the storage tank 11, and a cutter 13 is supported in the rear of the storage tank 11 so as to be openable and closable.

The bottom of the storage tank 11 has a hopper shape, and two paddy discharge ports 15 are provided in the front and rear. A paddy receiving floor 17 is provided below the discharge port 15, and a paddy bag is placed during the paddy packing operation. An auxiliary floor 19 is attached to the outer edge of the paddy receiving floor 17. The auxiliary floor 19
Is supported so as to be able to swing upward by two mounting portions 21 provided at the end portion on the main body side and a support pin 20 of the paddy receiving floor 17 on the main body side through which the mounting portion 21 is inserted, and swing upward. It is stored by standing up. Reference numeral 23 is a front auxiliary floor, which is attached to the front end side of the auxiliary floor 19 and is tilted backward to be stored.

As shown in FIGS. 1 and 3, one end of the support rod 25 is pivotally supported at the rear end side of the auxiliary floor 19 at a fulcrum 25a. A lock plate 29 is attached to the other end of the support rod 25.
Is fixed. As shown in FIG. 1, a guide groove 31 is formed in the lock plate 29 in an L-shaped slit shape.

The guide groove 31 is a lateral guide formed in the axial direction of the support rod 25.
31b and a vertical guide 31a formed substantially at right angles to the axial direction. In addition, an engagement recess 35 with which a pin 37 that is inserted through the guide groove 31 is engaged is formed at the upper end of the vertical guide 31a.

The pin 37 is provided so as to project from the rear end of the paddy receiving floor 17 on the main body side, and slides in the guide groove 31 as the auxiliary floor 19 swings.

The operation of the above-described lock mechanism will be described. As shown in FIG. 3, when the auxiliary floor 19 is horizontal, the pin 37 is in the lateral guide 31b of the guide groove 31, and the support rod 25 is the auxiliary floor 19. It is attached horizontally along.

When the auxiliary floor 19 is swung upward, the fulcrum of the support rod 25
The portion 25a rises, and the lock plate 29 is rear view (first
(Fig. And Fig. 3) move to the right. At this time, the pin 37 slides leftward in the lateral guide 31b with respect to the lock plate 29. When the auxiliary floor 19 moves to a substantially upright state, the distance between the pin 37 and the fulcrum 25a becomes maximum, the lock plate 29 moves leftward, and the pin 37 slides rightward with respect to the lock plate 29. As shown in FIG. 1 and FIG. 4, when the auxiliary floor 19 is further moved to a stored state in which the auxiliary floor 19 is tilted toward the main body side by a predetermined angle from the upright state, the pin 37 is located at the right end of the lateral guide 31b of the guide groove 31. When the lock plate 29 reaches the upper end of the vertical guide 31a, the lock plate 29 falls along the vertical guide 31a due to the weight of the lock plate 29 and the supporting rod 25. Since the guide groove 31 of the lock plate 29 is biased to the left by the weight of the lock plate 29 and the supporting rod 25 and the weight of the auxiliary floor 19 which tends to fall toward the main body,
The engagement recess 35 provided on the right side of the upper end of the vertical guide 31a has the pin 3
It is pressed against 7, and the movement of the lock plate 29 is restricted.

By restricting the movement of the lock plate 29 in this manner, it is possible to prevent a trouble in which the support rod 25 is unlocked due to vibration or flip-up when the combine 1 is moved, and the auxiliary floor 19 falls down in a horizontal state.

FIG. 5 is a partial rear view showing the second embodiment of the present invention.
In the structure of this embodiment, the lock plate 30 is fixed to the main body 3 side, and the pin 37 is formed by bending the tip of the support rod 25 forward. The guide groove 32 is provided in the opposite direction to that of the first embodiment, and the engaging recess 36 is formed at the lower end of the vertical guide 32a. In this embodiment, the lock plate 30 does not move, and the pin 38 slides as the auxiliary floor 19 swings.

FIG. 6 and subsequent drawings are sectional views of the storage tank 11. A dust suction port 43 is provided on the periphery of the discharge port 15, and the dust suction port 43 is connected to a dust passage 47. A dust passage 45 is also provided inside the storage tank 11. It is connected to the dust passage 47. As shown in FIG. 7, the dust passage 47 extends to the Karato fan 55, and the rotation of the Karato fan 55 sucks air from the dust inlet 43. At this time, dust generated by the discharge of the paddy and the storage case
The dust inside 11 is also sucked in, and it becomes possible to perform a clean padding operation. The sucked dust passes through the sorting chamber 57 and is discharged to the outside of the combine 1 by the fan 59.

Similarly, FIGS. 8 and 9 show that dust is absorbed by the cooling air of the engine 49. When the engine fan 51 rotates, cooling air is drawn into the engine room from the air intake 53. At the same time, dust is sucked in through the dust suction port 43 and discharged together with the cooling air. Since the engine room is partitioned by the dust passage 47, the dust wind does not hit the engine 49 directly.

<Effect of the Invention> According to the structure of the present invention configured as described above, since the guide groove of the lock plate is L-shaped, the pin is automatically locked by the weight of the supporting rod when the auxiliary floor is stored and assisted. Since the swing of the floor is regulated, no special lock operation is required.

Also, in the locked state, the pin and the engaging recess are securely engaged by the weight of the support rod, so the support rod does not unlock due to vibration or flip-up during movement, and the auxiliary floor falls when the main body moves. Such troubles can be prevented.

Furthermore, since it has a simple structure that does not use a special part for locking such as a spring, it has effects such as low manufacturing cost and easy mounting.
