With the feeder house 28 fixedly held by the lock fitting 29 and the platform 21 grounded, the cylinder 5 is placed against the reaping pretreatment section 4.
At the same time, if necessary, set the pawls 31, 31 on the rear traveling gear 2, and then attach the cylinder 5 in the hanging state to the vehicle body 3 using the bolt 27.
By driving and extending the cylinder 5 in a state where the cylinder 5 is fixed to As shown in FIG. 5, the tire-type front traveling device 1 can be replaced with a crawler-type traveling device 39, or the traveling devices 1 and 39 can be removed.
即ち、本来備える刈取前処理部制御用のシリン
ダ５を車体昇降用のジヤツキとして利用できるよ
うにしてある。 That is, the cylinder 5 originally provided for controlling the pre-reaping processing section can be used as a jack for raising and lowering the vehicle body.

ダ５の制御系に無理がかかつたりしやすくなる。 In this way, when the cylinder 5 is used as a jack, since the cylinder 5 is a single-acting operation type,
When reconnecting the cylinder rod 18 to the reaping pre-treatment section 4, it is necessary to manually contract the cylinder 5, and if the cylinder 5 is made double-acting, it will not be possible to operate the cylinder 5 during normal reaping work. When the reaping pre-processing section 4 is grounded, the reaping pre-processing section 4
Even though the cylinder has touched the ground, the pre-reaping treatment section 4 may continue to be forcibly lowered due to incorrect operation, which may damage the pre-reaping treatment section 4 or overload the control system of the cylinder 5. It becomes easier to get rid of.
このような不都合を伴わせないようにするため
には、シリンダ５の油圧制御回路を第６図に示す
ように構成すれば良きものである。 In order to avoid such inconvenience, the hydraulic pressure control circuit for the cylinder 5 may be constructed as shown in FIG. 6.

よつて、シリンダ５を単動操作する状態と複動操
作する状態とが得られるようにするのである。 That is, a hydraulic pump P and a hydraulic oil tank T are connected to the cylinder 5, and a spring return type single-acting operating valve V1 and a double-acting operating valve V2 are interposed in parallel in the middle of the oil path, and the single-acting The operation valve V1 is provided with a port for driving and operating the cylinder 5 in the extension direction, a port for operating the cylinder 5 in the contraction direction by the weight of the reaping pretreatment section 4, and a port for fixing the cylinder 5, Further, the double-acting operation valve V2 is provided with a port for telescopically operating the cylinder 5 and a port for fixing the cylinder 5, so that the cylinder 5 can be operated in a single-acting manner by selecting both the valves V1 and V2. This makes it possible to obtain a state in which the actuator operates and a state in which it performs double-acting operation.

る。 As shown in FIG. 7, the operating mechanism for both the valves V1 and V2 is constructed by providing one valve operating lever 12 that is slidable in the axial direction with respect to its swing shaft. A metal fitting 35 that selectively engages and connects the spools 14 and 15 as the lever 12 swings is connected to the lever 12, and the metal fitting 3
5 is provided with a biasing mechanism 36 for engaging and biasing the spool 14 of the single-acting operation valve V1, and is interlocked with switching to the hanging state due to its own weight when the cylinder 5 is disconnected from the reaping pretreatment section 4. and an interlocking mechanism 37 that automatically and reversibly engages and connects the operating lever 12 to the spool 15 of the double-acting operating valve V2 against the urging force of the urging mechanism 36. Switching between the first and second operating states is automatically performed.

着脱を行う事ができて便利である。 Generally, a three-point link of a large tractor or a crane truck is used to attach or remove the crawler-type front traveling device 39, but a trolley 40 shown in FIGS. 4 and 5 can be used. Accordingly, the traveling device 39 can be easily attached and detached by one person, which is convenient.

用できる。 This trolley 40 has a frame 41 on which a crawler-type traveling device 39 is mounted, and four wheels 42 . 41, which is removably attached to the traveling device 39.
The stopper 43 is engaged with the inner end of the crawler when removing it, and the stopper 43 is engaged with the outer end of the crawler with respect to installation, and the cart 40 is pulled or pushed by a tiller or the like. Alternatively, it may be configured to be self-propelled by mounting a small engine, and in either case, the trolley 40 can be used as a transport vehicle.
尚、前記転輪４２のうち、少なくとも前後一方

As explained above, in order to avoid unreasonable pressing of the reaping pretreatment section to the ground, the present invention disengages the cylinder, which is normally configured to take a single-acting control mode. Therefore, this cylinder is configured to be automatically switched to a double-acting control mode, and the cylinder can be expanded and contracted while in contact with the ground to easily raise and lower the traveling vehicle body, and can be connected to the reaping pre-processing section, or The front traveling gear can be easily replaced or removed, and this allows the cylinder for raising and lowering the reaping pre-processing section to be replaced with the vehicle body lifting jack for replacing or removing the front traveling gear. This has made it possible to eliminate the need for jacks for raising and lowering the vehicle body, which were previously required, and it has become possible to reduce the cost of the combine harvester itself.

ンダの制御系に無理をかけたりする等の欠点も旨
く解決できる利点がある。 Furthermore, compared to the conventional case where the cylinder for raising and lowering the reaping pretreatment section is used as a jack for raising and lowering the traveling vehicle body, since the cylinder can be of a double-acting type, it is easier to reconnect the cylinder rod to the reaping pretreatment section. In addition, there is no need to manually contract the cylinder, and on the contrary, the cylinder is made double-acting, and compared to the case where it is used as a cylinder for raising and lowering the pre-reaping section, the reaping pre-processing section can be easily used during normal reaping work, etc. When lowering the reaping preprocessing part to the ground, even though the reaping preprocessing part has touched the ground, the forcible lowering of the reaping preprocessing part continues due to an incorrect operation, which may damage the reaping preprocessing part or force the cylinder control system. It has the advantage of being able to effectively resolve drawbacks such as
また、単動操作と複動操作をシリンダの連結解
除によつて自動的に切り換えを行うので、各操作
時の誤操作を完全に防止でき、従つてそれに神経
を使うことがなく、オペレーターの負担が少なく
てすむ。 In addition, since single-acting and double-acting operation are automatically switched by uncoupling the cylinder, it is possible to completely prevent erroneous operation during each operation, so there is no need to worry about it, and the burden on the operator is reduced. Less is needed.
特に、刈取作動時には、条合わせや回向操作そ

それだけでオペレーターの負担が大きいので、自
動的に切り換えを行う効果は顕著である。 In particular, during reaping operations, row alignment, turning operations, and other various operations must be performed at the same time.
This alone places a heavy burden on the operator, so the effect of automatically switching is significant.
さらに、車体昇降作業時においても、刈取部の
着脱、クローラの交換などの重作業を行わなけれ
