この発明は４輪駆動方式の乗用農機、特に乗用
田植機における前輪のデフロツク装置に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a front wheel deflock device for a four-wheel drive type riding agricultural machine, particularly a riding rice transplanter.
代掻後の圃場は畦際では圃場表面が一般にやや
高くなつており、この畦際から少し離れた附近で
は圃場面が低くなつているので、植付作業の際に
畦際にて回向操作をするとき機体が少し回向を始
めれば回向内側の前車輪に対してやや前位となる
回向外側の前車輪は高くなつている畦際の圃場面
に乗り上げることになり、これに対して回向内側
の前車輪は低くなつている圃場面から浮上り気味
の状態となり、この結果、回向内側の前車輪は抵
抗がなくなつて急速に回転を始めるが、外側の前
車輪は圃場から受ける大きい接地抵抗のために停
止気味となる。したがつて機体は回向操作の方向
に円滑に回向できなくなり、このように回向性能
が低下すると云う問題がある。 After plowing, the field surface is generally slightly higher at the edge of the ridge, and the field surface is lower near the edge of the ridge, so turning operations are carried out at the edge of the ridge during planting. When the aircraft begins to turn a little when turning, the front wheel on the outside of the turn, which is slightly forward of the front wheel on the inside of the turn, will run onto the raised field at the edge of the ridge. As a result, the front wheel on the inside side of the turning section is in a state of rising from the low-lying field, and as a result, the front wheel on the inside side of the turning section loses resistance and begins to rotate rapidly, but the front wheel on the outside side is lowered in the field. Due to the large ground resistance it receives from the ground, it almost stops. Therefore, the aircraft cannot turn smoothly in the direction of the turning operation, and there is a problem in that the turning performance is degraded in this way.
又、前輪がセツターピボツトを有しないもの
は、前輪の片輪が畦畔で機体が左右に傾くとき、
左右後輪とのり上つた片方の前輪とで下位側の前
輪が接地せずに浮上つて無抵抗で空転し、前輪牽
引力がなくなると云う問題がある。 Also, if the front wheels do not have a setter pivot, when one of the front wheels is on a ridge and the aircraft leans to the left or right,
There is a problem in that between the left and right rear wheels and one of the front wheels that has climbed up, the lower front wheel does not touch the ground but floats up and spins without resistance, causing a loss of front wheel traction.

している。 In addition, the rear wheel drive mechanism of this passenger aircraft includes left and right drive chain cases 1 fixed to the transmission case 2.
Left and right rear wheels 16, 16 are pivotally supported at the rear of wheels 5, 15, respectively, and a rear wheel differential gear mechanism 18 is operated by a transmission gear mechanism 17 that drives the front wheel differential gear mechanism 11.
The left and right rear wheel drive shafts 19, 20 are driven by the drive chain mechanisms 21, 21.
Since the rotational power of the wheels 9 and 20 is transmitted to the rear wheels 16 and 16, the traveling brake mechanism 22
As shown in FIG. 3, brake drums 23 are fixedly attached to the left and right rear wheel drive shafts 19, 20, respectively, and the brakes have a rectangular cross section and are inserted between one end of two brake shoes 24, 24. If the cam pin 25 is rotated, the brake shoes 24, 24 will release the return spring 2.
6 and 26, and is pressed against the inner peripheral surface of the brake drum 23 to apply a brake to the rear wheel drive shafts 19 and 20. On the other hand, a brake pedal L is mounted on a brake pedal shaft 29 that is rotatably supported by bearings 28, 28, and a brake pedal R is mounted on a brake pedal outer shaft 30 that is rotatably fitted onto the brake pedal shaft 29. The arms 31, 31 attached to the brake pedal shaft 29 and the brake pedal outer shaft 30, respectively, are linked to the arms 32, 32 attached to the brake cam pins 25, 25 of the left and right brake drums 23, 23, respectively. When the brake pedals L and R are depressed, the respective brake cam pins 25 press the brake shoe 24 against the brake drum 23.

となるようにした連動機構４４に構成している。 Further, the aforementioned front wheel differential lock mechanism 14 has a clutch arm 35 attached to a rotating shaft 34 which is provided to rotate in conjunction with the depression operation of a differential differential pedal (not shown).
Since the block 36 that engages with the shifter groove 12b of the differential clutch 12 is pivotally connected to the clutch arm 35, in this invention, the differential arm 37 is attached to the rotation shaft 34. , the pedal arm 38 is attached to the brake pedal shaft 29.
In addition, a pedal arm 39 is attached to the brake pedal outer shaft 30, and a flexible tube 4 attached to the machine frame is attached to the brake pedal outer shaft 30.
Attach the front end of the defrock wire 41 that has been passed through to the diffraction arm 37, and as shown in FIG.
2. Attach the defrot wire 41 to the base 43 that is locked at 2.
By locking the rear end, when at least one of the left and right brake pedals L and R is depressed, the pin 42 will not engage the other pedal arm due to the arcuate grooves 38a and 39a of the pedal arms 38 and 39. Without rotating at the same time, the depressed pedal arm connects the differential clutch 12 via the differential wire 41.
The clutch pawl 12a rotates to the defrock position where it engages with the clutch pawl 8a of the ring gear 8, and when the depressed brake pedals L and R are returned to the brake release state, the defroc wire 41 is loosened and returned. An interlocking mechanism 44 is constructed in which the clutch pawls 12a, 8a are disengaged by the spring 13, resulting in a deflock released state.

回転駆動されることになる。 Since the front wheel differential lock device according to the present invention is constructed as described above, during normal planting work in the field, the differential clutch 12 is maintained in the disengaged state in which it does not mesh with the ring gear 8, and therefore the left and right The front wheels 1, 1 are driven to rotate independently of each other.

とになつてデフロツクの状態となる。 When at least one of the brake pedals L and R is depressed to decelerate the aircraft in order to turn around at the edge of a ridge, the travel brake mechanism 22 is activated and brakes are applied to the rear drive shaft 19 or 20, or both. It will work. Also, at the same time, pedal arm 3
8 and 39 also rotate, so the deflock wire 41 pulls the deflock arm 37. Therefore, the clutch pawl 12 of the deflock clutch 12
a fully meshes with the clutch pawl 8a of the ring gear 8, and the left and right front wheel drive shafts 3, 4 rotate as one, resulting in a differential lock state.

ツク解除の状態に戻るのである。 In this way, when the defrock condition is reached, both the left and right front wheels 1, 1 rotate as one unit, so as mentioned above, even if the front wheel on the inside side of the turning side tends to float up, or the front wheel on the outside side of the turning side Even when the wheels dig into the ground and the ground resistance increases, the left and right front wheels 1 and 1 become one unit, so only one front wheel rotates rapidly or slips. The aircraft is able to turn while moving forward reliably without any hesitation, and the aircraft can turn smoothly in response to steering operations. Then, when both the brake pedals L and R are returned to the brake release state, the differential wire 41 is loosened, and the clutch claw 12a of the differential clutch 12 is disengaged from the clutch claw 8a of the ring gear 8 due to the return spring 13. It returns to the state where the deflock is released.

Even if this happens, the front wheel defrock mechanism works at the same time, so the front wheels that have climbed up can reliably rotate and turn, allowing the aircraft to turn smoothly and reliably.
