Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a working part drive device for a transplanter, etc.
It can also be used for seeding machines, etc.

Problems to be Solved by the Invention In a working machine such as a transplanter that inserts seedlings at regular intervals while moving the machine forward into the field, even if the interlocking relationship between the machine's progress and the transplanting section is maintained constant. , If there is a slip in the progress, the transplant interval of the transplant work section is likely to change.

Means for Solving the Problem This invention provides an interlocking mechanism for driving a running section (2) and a working section (3) by a prime mover (1).
The interlocking rotation of the ground wheel and the grounding ring that rotates while touching the soil surface (4)
A working part drive device for a transplanter or the like is provided with a transmission (6) that changes gears to synchronize the working part (3) with the traveling speed by a sensor (5) that compares the rotation of the working part (3) with the traveling speed. .

Operation and Effect of the Invention When the prime mover (1) is driven, the wheels, which are the traveling part (2), are rotated to propel the aircraft, and the working part (3) is moved through the transmission (6). The vehicle is driven to carry out a predetermined work on the soil surface, and since the grounding wheel (4) is rotating and touching the soil surface, the traveling speed by this grounding wheel (4) and the working part (3) are linked. When the rotational speeds match, the gear ratio of the transmission (6) is used as is, but if a slip occurs in the traveling section (2) or the working section (3) When the sensor (5) detects a rotation difference between the rotation of the grounding ring (4) and the interlocking rotation of the working part (3) due to an overload on the grounding ring (
When the rotation on the 4) side decreases, the transmission (6) f! : The working part (3) is decelerated by interlocking operation, and when the working part (3) becomes overloaded and the rotation decreases, the transmission (6) is fully interlocked to speed up the working part (3). The operation of the working part (3) can be performed in synchronization with the traveling speed of the working part (3), and the working part (3) can perform work with accurate traveling speed synchronization while being driven in conjunction with the working part (3). can.

Embodiment In the illustrated example, the rear end of the fuselage (7) has a pair of left and right running unit (2) wheels, and an original vJ machine (1) that interlocks these wheels.
), and the interlocking case (9) under the seat (8) is equipped with an interlocking mechanism that receives instructions from the prime mover (1) and interlocks with the running section (2), and also connects the working section (3). A power take-off shaft QO is provided. The front part is provided with auxiliary wheels α1), and a seedling transplanting device is mounted as a working part (3) on the upper part of the machine body (7).

α-shi is a rotatable groove cutter that cuts grooves into the soil surface, and a groove-cutting machine that fully opens the planting groove in the groove-cutting part of α-3. A pair of left and right planting wheels α→ for inserting seedlings into the planting groove is provided, and a seedling feeding device holds seedlings for each planting stock above the planting wheels α4) and supplies them to the planting wheels α→. αSk is provided.

The transmission (6) is a continuously variable transmission that can change speed from 0 rotations to a high speed range, and is interlocked from the power take-up high shaft α0 to the flexible shaft αQ, and is connected to the output shaft (17) and the working part (3). The working part (3) interlocks the chain between the input shaft (to) and rotates the belt from the input shaft (to) to rotate the seedling feeding device 05, and the planting wheel Q4)'t. It also rotates in conjunction.

The grounding ring (4) is located on the outside of the planting wheel αa and
), the sensor (
5) Cheno (goods) is interlocked with axis (a). The sensor (5) consists of a shaft (A), a sprocket-boss that is screwed onto the shaft, and a sprocket (C) that is fitted with a spline.
, and an operating mechanism for operating the transmission (6),
The sprocket (c) boss rotatably bears on the bearing seat of the fuselage (7) and is at one end of the chain. The sprocket (C) is provided between the output shaft αη and the chaino (5) to interlock with each other, and the rotation difference between the two sprockets (C) causes the shaft (A) to move between the sprocket and l-( ) It has an interlocking structure that moves left and right in the axial direction with respect to the boss part. (Company) is the spring between both sprockets.

At the tip of the shaft, there is an actuating piece @ that is rotated by the protrusion and retraction of this shaft (A), and this actuating piece (to) and the transmission (6)
Adjustable telescopic adjustment between the operation arm 4 and the CL, C (to)
It is connected with. 01) is a spring. In this interlocking operation, when the rotation of the sprocket (to) decreases relative to the sprocket (to), the shaft @ is moved in the direction of the arrow (A), and the actuating piece (to) is suppressed and rotated. ), and when the rotation of the sprocket (C) decreases relative to the sprocket ■, the shaft 1221 is moved in the opposite direction of the arrow (A), and the actuating piece @ is pulled back by the spring force to create the transmission (6). are assumed to move in relation to each operation in order to link the gears with each other.

The wheel running section (2) is interlocked with the drive of the prime mover (1) to move the aircraft (7) forward (b), and at the same time, the power number is 1b.
The working part (3) is interlocked through the shaft αQ, the burnable shaft αe, the transmission (6), the output shaft αη, the Cheno α9, the input shaft (to), etc., and the groove is made at the position created by the groove maker αa. , supply device α9V
Therefore, the seedlings supplied by C are planted at regular intervals using the planting method α (1). The rotation of the output shaft αη rotates the sprocket (c) via the chain @X, and as the aircraft advances, the grounding ring (4) rotates, which rotates the sprocket (to) in the same direction via the chain (23). .

When both sprockets L24 (c) have the same rotation speed, the shaft (a) does not move to either the left or right side, so the gearbox (6) interlocking with the working part (3) does not change gears either high or low. However, when the wheels slip and the forward speed of the aircraft (b) by the running part (2) decreases, the ground contact rotation of the grounding wheel (4) decreases accordingly, so the sprocket ( The rotation speed of the sprocket (to) decreases with respect to the rotation of (c), and this sprocket (to) F2
41 By the threaded connection between the boss part and the shaft), move this shaft in the direction of arrow (a) to release the actuating piece into the spring e3]
), and the gearbox (6) is rotated through the rod (6).
) to reduce the seedling planting speed of the working device (3). Further, when the forward movement (b) of this machine body is sequentially decelerated and comes to a stop state, the planting speed of the working device (3) is also decelerated and eventually comes to a stop.

Conversely, the working part (3) is overloaded and the sprocket (
When the rotation of the shaft (A) is reduced and becomes lower than the rotation of the sprocket (A), the shaft (A) is
In order to be moved in the opposite direction, the actuating piece (c) is returned in the opposite direction by the spring Gη, and the transmission (, 6) is moved in the opposite direction.
is operated so that the output shaft αη rotates at a high speed by increasing the speed, and the planting speed of the working part (3) is set to a high speed, and the planting speed of the working part (3) is increased to move forward (b).
Becomes attuned to speed.
