Description

Detailed Description of the Invention In general, mobile threshing machines repeatedly move and stop, collect grain bundles around the stopping position, and thresh them sequentially. It was troublesome to have to return to the station frequently to stop the aircraft, and work efficiency was extremely low.

The present invention aims to improve the various drawbacks mentioned above by reducing the traveling speed to match the bundle feeding speed in conjunction with the operation of the clamping conveyor of the threshing device to clamp and convey grain culm bundles. In a mobile threshing machine in which a self-style threshing device is mounted on a machine base having a traveling device and the bundled husk is made into 11 (a) grains, the husk holding and conveying device of the threshing device is Characteristic 41.1 is that the machine is configured to be connected to the traveling device via a deceleration device to achieve a speed of 11 times during threshing operation.

Hereinafter, an example of small 1-A will be explained with reference to the drawings. 1 is a threshing device mounted on the front part of a machine base having a traveling device 2, and an engine 3 is disposed at the rear of the threshing device, and an engine 3 is installed at the rear of the threshing device. is provided with a control section 4 consisting of a steering lever, a handle, a speed change lever, etc., and the threshing device 1 is provided with a feed body [i] whose rear part is a handle in front of the feed port, and a feed body [i] is provided on the outside of the handling port. A shell culm clamping conveyor 6 consisting of a naen 6a and a pincher l/-le 6b is installed oppositely, and a straw drainer is placed at the end thereof. a
A straw transporting body 7 consisting of a guide rail 7b and a guide rail 7b is arranged in series.

The pulley 8 of the engine 3 is connected to the manual pulley 3a of the transmission 9 by a belt IG, and to the manual pulley 9-11a of the threshing transmission case 11 by a belt 12, and is supported by a fulcrum shaft 13. There is L
A clutch pulley 15 is pivotally supported at one end of the mold arm 14.

Then, the other end of the above-mentioned arm 14 is connected to the clutch arm 1.
6 is connected to one end of the clutch arm 16 by a wire 17, and a boss located in the middle of the clutch arm 16 is loosely fitted onto a vertical shaft 20 on a rotary body 18 supported by a horizontal shaft 18 protruding from the plate wall of the thresher l. , a long hole 1 bored in the other end of the clutch arm 16 [(a is the OFF arm 21 of the switching lever 21
A is inserted, and the ON arm 21b protruding from the top of the switching lever 21 is exposed to the upper part of the switching lever 21, and the base of the switching lever 21 is rotatable to the front end of the bending rod 23 supported by the bearing 22. Since it is supported pivotably and has return springs 24 and 25 interposed therebetween, it can tilt back and forth and left and right.

Further, as shown in FIG. 3, the rail piece 6b' at the starting end of the pinching rail 6b is made to be higher near the starting end of the side part, and an adjustment plate 26 is placed at this higher part to adjust the movement in the conveying direction. The push rod 28 attached to the bottom plate of the rail piece 6b' has a flange 28 at its lower part, and its lower end faces above the notch 30 of the clutch arm 16. I'm here.

In the mobile threshing machine described above, during threshing work, if the speed change lever is set to the low speed position and the switching lever 21 is set to the cutting position of the horizontal guide plate 31 and the front and rear guide plate 32 as shown in FIG. , the wire 17 is loosened and the clutch pulley 15 is separated from the belt IO as shown in FIG. It is directly above the. In this state, when the stock part of the shell culm bundle 33 is fed to the starting end of the shell culm clamping conveyor 6, the clamping rail 8b
The rail piece 6b at the starting end of the push rod 6b is pushed down, and the push rod 28 is lowered, and the collar 28 at the bottom pushes down the front part of the clutch arm 16, so that the rear part is connected to the L-shaped arm 14 via the wire 17. By pulling the rear part, the clutch pulley 15 tensions the belt 10 and the aircraft moves forward. When the shell bundle 33 passes through the adjustment plate 26 formed integrally with the rail piece 6b', the push rod 28 moves the rail piece 8
b', the wire 17 relaxes, the clutch pulley 15 is disconnected, and the aircraft stops.

This intermittent operation of the clutch pulley 15 is repeated every time a bundle of shell culms is supplied, and the st body moves forward only when the bundle of shell culms 33 is supplied, and stops while carrying the bundle.
As a result, the actual traveling speed is reduced to large 'I'i+i.

Furthermore, if the adjusting plate 26 is moved to the lower side as shown by the solid line in FIG. If you adjust the movement to ``='', the travel distance will become smaller.

When the switching lever 21 is tilted to the left as shown by the chain line in FIG.
The FF arm 21a pushes the clutch arm 16 to the left,
Since the notch 3o retracts laterally from the lower part of the push rod 28, even if the push rod 28 descends when the culm bundle is supplied, the clutch arm 16 will not be pushed down, and the machine will stop at a fixed location. There is.

Furthermore, when the switching lever 21 is tilted forward as shown by the chain line in FIG. 6 and held on the front four parts of the guide plate 32,
Since the ON arm 21b holds the clutch arm 16 in a depressed state, the clutch pulley 15 is pressed down (bell) 10
The aircraft continues to operate under constant pressure.

As mentioned above, when threshing work is performed while the machine is running intermittently, if the husk holding conveyor 6 becomes clogged, the fourth
The clogged microswitch S1 shown in the figure continues to be ON,
This microswitch f S + is inserted into the engine control circuit shown in FIG. 7 together with a timer T, relay R, and normally closed switch S2, so that if the microswitch S1 is turned on for more than the time set by the timer T, Since the relay R is turned OFF and the engine 3 is stopped, the culm clamping conveyor 6 is not damaged, and the threshing device 1 can be stopped before the clogging becomes serious, thereby reducing the work to remove the clogging. .

Further, as shown in FIG. 6, when the switching lever 21 is tilted to the forward clutch engagement position, the normally closed switch S2 is turned off.
Since it is installed so that the engine 3 is set to F, even if the micro switch S1 is turned on due to a pile of straw or other causes during continuous flight, the engine 3 will not stop and the aircraft will not come to a sudden stop. It can be prevented.

The present invention provides a machine base-1- having a traveling device as described above;
In a mobile threshing machine equipped with a self-described threshing device to thresh bundled grains (111), 1) the culm clamping and conveying device of the 17th threshing device ξ is linked to the traveling device via a speed reduction device; Since the mobile threshing machine is configured to reduce the traveling speed during threshing work, the mobile threshing machine runs slowly at a speed commensurate with the supply of bundles to the husk holding conveyor, and it is not possible to stop or run the machine. By omitting the complicated operations of
1? ε grain, and work efficiency can be significantly improved.
