A return spring 33 has one end locked to the shaft 32 and the other end locked to the movable rear frame 17 side, and biases the rod 31 of the cylinder 30 in the direction of contraction. The return spring 33 becomes unnecessary when the cylinder 30 is a double-acting cylinder.

[0010]The operating section A, which is composed of the rods 24, 25, the bell crank 26, the shaft cylinder 27, and the shaft 28, has the mounting base frame 13 and the front frame on the body side.

When the middle part of the hose 55 is held and the threshing device 14 is moved backward, the length of the harness/hydraulic hose 55 is extended, and when the mounting frame 13 is retracted, the support arm 54 is moved downward by the spring elasticity. Rotation eliminates looseness. Reference numeral 56 designates a cutting body of the reaping unit 5, 57 a pulling device, 58 a narrow guide, 59 a transmission, 60 a drive wheel, and 61 a grain discharge auger.

[0014]

[Effect] Next, the effect will be described. Since the present invention has the above-mentioned configuration, the machine is moved forward, the grain culms are harvested by the reaping section 5, the grains are threshed by the threshing device 14, and the threshed grains are temporarily stored in the grain tank 15.

After the work is finished or before the start of the work, maintenance such as inspection and repair of the transmission mechanism provided in the traveling device 2 and the engine room 11 is carried out. It is composed of a frame 6, a rear frame 7 on the fuselage side, and a mounting frame 13. Since the threshing device 14 and the grain tank 15 are provided, when the mounting frame 13 is moved rearward relative to the front frame 6 on the machine side, the threshing device 1 on the mounting platform frame 13 is removed.
4 and the grain tank 15 move backward together with the mounting frame 13 to form a large space between the front surface on the side of the thresher 14 and the side of the engine room 11, and the engine 12 and the transmission mechanism from the engine 12 to the thresher 14. In addition, since the upper surface of the traveling device 2 is exposed, maintenance thereof can be facilitated.

In this case, when a person is seated on the control section 10 and performs an operation to extend the rod 31 of the cylinder 30, the rod 31 pushes the arm 29, and the arm 29 moves the shaft cylinder 27 into the shaft 2.
8, the shaft cylinder 27 rotates the bell crank 26, and the bell crank 26 pulls the rods 24, 25, so the supporting legs 20, 21 rotate around the horizontal axis 22,
The casters 23 at the lower ends of the supporting legs 20 and 21 are in contact with the ground, and the casters 23 absorb the resistance caused by the rotation of the supporting legs 20 and 21.
rolls on the ground and decreases, and the supporting legs 20 and 21 are easily brought into a spread state.

Therefore, the mounting frame 13 is supported by the rollers 19 of the movable front frame 16 on the front side and by the support legs 20 and 21 on the rear side, and in this state, the traveling device 2 is driven and the threshing device 14 and When the control unit 10 side is moved forward while leaving the grain tank 15, the mounting frame 13 will relatively slide rearward.

At this time, since the support legs 20 and 21 are attached to the mounting frame 13 so as to be rotatable in the left and right directions by means of a transverse axis 22 in the front and back direction, even if the control unit 10 side is moved forward, the support legs 20 and 21 will not fall. Furthermore, since the lengths of the supporting legs 20 and 21 are configured so that when the casters 23 touch the ground, the moving side rear frame 17 of the mounting frame 13 is lifted up, the supporting legs 20 and 21 are rotated to raise the casters 23. When grounded, the mounting base frame 13 is supported to the extent of being lifted, reducing sliding resistance.

[0019] A locking mechanism B consisting of an engaging hook 40 and an engaging part 42 is attached to the operating part A on the supporting leg 2.
When the legs 0 and 21 are opened, the lock is released, and the supporting legs 20,
21 are connected in a related manner so as to lock when the legs are closed, the bell crank 26 rotates due to the contraction of the cylinder 30, and the rotation of the bell crank 26 pushes the connecting rod 35, causing the arm 36 to rotate. Rotate arm 3
6 rotates the lock operating rod 37, which rotates the lock release arm 39 upward, and connects the engagement hook 40 on the mounting platform frame 13 side to the engagement portion 42 on the front frame 6 side of the fuselage. to automatically release the lock. Therefore, when the supporting legs 20, 21 are opened, the engagement hook 40 is unlocked in conjunction with the opening operation. Note that before operating the cylinder 30, the rotating plate 51 is rotated to release the lock.

After the maintenance is completed, when the traveling device 2 is driven to move the control unit 10 side backward, the mounting frame 13 moves forward relatively, and the guides 45, 45 on the mounting frame 13 side move backward. The fixed side rear frame 32 of the fuselage side rear frame 7 comes into contact with the guide parts 46 , 46 , and the guide guide 45
, 45 move and guide the mounting frame 13 toward a proper position on the rear frame 7 on the body side while slidingly contacting the outside of the fixed side side frames 9, 9.

When the control unit 10 side is further moved backward to a predetermined position, the fixed side rear frame 8 of the aircraft side front frame 6 approaches the movable side front frame 16 of the mounting frame 13, and the mounting frame 1
The engagement protrusion 47 on the third side enters the engagement hole 48, and the engagement protrusion 47
The tip of the rotating plate 51 is rotated by contacting the contact portion 52 of the rotating plate 51.
The engaging bent portion 53 of the rotary plate 51 engages with the rear surface of the movable front frame 16 to fix the front side of the mounting frame 13 to the rear frame 7 side of the body.

Next, when the operation section 10 is operated to release the extension of the cylinder 30, the rod 3 of the cylinder 30
1 is contracted by the elasticity of the spring 33 and pulls the arm 29, and the arm 29 rotates the shaft cylinder 27 about the shaft 28 in the opposite direction. , 25, the rods 24 and 25 rotate the support legs 20 and 21 closed around the horizontal axis 22 and store them. The cylinder 30 is moved by the rod 3 due to the elasticity of the spring 33.
1, it acts as a damper and the support leg 20
, 21 slowly closes its legs.

At the same time, the rotation of the bell crank 26 pulls the connecting rod 35 to rotate the arm 36, the arm 36 rotates the lock operating rod 37, and the rotation of the lock operating rod 37 causes the lock release arm 39 to rotate. Since the engaging hook 40 is detached from the lower surface, the engaging hook 40 rotates downward around the shaft 41 due to the elasticity of the spring 43 and engages with the engaging portion 42 on the front frame 6 side of the fuselage side, automatically. to lock.
