Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an agricultural machine with a fertilizing device, and can be used for high-level working machines such as rice transplanters and sowing machines.

Work with a fertilizing device in which a fertilizing device is attached to a working machine such as a rice transplanting device or a sowing device via a rolling mechanism provided in the conventional technology and a problem area that the invention aims to solve. In general, this fertilizing device is installed in a working device such as the rice transplanting device or the sowing device, and the fertilizer filled in the fertilizing device increases or decreases depending on the fertilization state, or changes depending on the amount filled. Variations occur, and these variations tend to disrupt the left-right balance of the working device and affect rolling performance.

Means for Solving the Problems This invention provides a lifting mechanism (3) for lifting and lowering a working device (2) such as a rice transplanting device or a seeding device at the rear of a traveling vehicle body (1).
) and a rolling mechanism (5) that rotates around an axis (4) in the front-rear direction, which is attached to the rear part of the elevating mechanism (3).
The agricultural working machine with a fertilizing device is provided with a fertilizing device (6) that is raised and lowered integrally with the working device (2) without rolling in the lifting mechanism (3).

A fertilizing device (6) to which a working device (2) is attached via the action mechanism (5) of the invention, provided on the lifting mechanism (3), and raised and lowered integrally with the working device (2), without rolling. For example, seedling planting work and fertilization work are carried out simultaneously while the running vehicle body (1) is filled with fertilizer to be spread on the ground, but due to unevenness of the soil surface, the running vehicle body (1) When tilted, the working device (2) pivots around the shaft (4) and tilts from side to side with respect to the traveling vehicle body (1) by the action of the rolling mechanism (5), maintaining parallel to the soil surface. The work is done while

(19) is formed in a concave shape in plan view so that the rear end side thereof sandwiches the seedling device (17).

The lifting mechanism (3) includes left and right upper links (20).
(20) and the lower link (21) (21), and between this support frame (22) (22) the connecting frame (
23), a rolling shaft (4) is provided extending rearward from the center of the lower part of this connecting frame (23), and the planting frame (15) is
) It is rotatably fitted into a rolling post (24) that protrudes forward from the center. Also, the support frame (22) (2
2) is provided with an arm (25) projecting to the left and right at the top,
The tip of this arm (25) and both left and right sides of the planting frame (15) are connected by springs (26), and the working device (2) in a rolling attitude with respect to the traveling vehicle body (1) is neutralized. The rolling mechanism (5) is configured to spring into position.

In addition, a horizontal sensor is provided on the side of the traveling vehicle body (1), and a telescopic cylinder is provided between the lifting mechanism (3) and the working device (2) to detect the inclination of the traveling vehicle body (1). The control structure may be configured to rotate the working device (2) around the rolling axis (4) and maintain it in a horizontal position.

The fertilizing device (6) is raised and lowered integrally with the working device (2) without rolling, and its base is attached to the support frame (22) of the lifting mechanism (3) in order to be mounted for this work. A frame (27) is provided whose tip side extends rearward through the lower side of the working device (2), and a rectangular fertilizer hopper (28) that is long in the left and right directions in plan view is attached to this frame (27). The hopper (28) is appropriately partitioned in order to fertilize the field where the seedlings have been planted by the seedling device (17) disposed on the working device (2), and a feeding chamber (29) is provided on the lower side.
A feeding shaft (30) passing through the midsection of this feeding chamber (29)
A feeding roll is attached to the feeding chamber (28), and the conduit (31) inserted into the bottom of the feeding chamber (28) is connected to the left and right flow (1B) (1B
), and central flow) (19) The fertilization guide (32) is inserted through the fertilizer guide (32) attached to the rear end side, and the fertilizer is fed out in fixed amounts from the fertilizer hopper (28) by the rotation of the feed roll. ), and the fertilization guide (32) forms a kerf while discharging into the kerf.

A body (1) that drives each part with power by starting the prime mover (7)
runs forward. The lifting mechanism (3) is operated by the lifting device (14).
), lower the working device (2) and the fertilizer applicator (6), and slide the left and right floats (18) (+8) and the center float (+8) onto the soil surface to lower the fertilizer applicator guide (
The seedlings loaded into the seedling tank (16), which is reciprocated from side to side by the planting frame (15) while forming kerfs with the seedling device (17), are transferred from side to side by the seeding device (17).
(18) and central flow 1-(19) to perform the planting work on the leveled soil surface, and at the same time, the fertilizer filled in the fertilization hopper (28) of the fertilizer application device (6) is transferred to the feeding shaft (3).

During this transplanting and fertilization work, the traveling vehicle body (1) has wheels (
11) When the working device (2) is tilted due to the unevenness of the plow plate (12), etc., the working device (2) is simultaneously tilted. For example, if the traveling vehicle body (1) is tilted to the left, this tilting causes the working device (2) to tilt. 2) also tilts to the left, and as a result of this tilting, the pressure applied to the bottom of the left float (18) changes, and if this pressure resists the spring (2B), the working device (2) moves to the rolling shaft (4). Rotate clockwise until it is almost parallel to the soil surface. On the other hand, if it tilts to the right, the pressure applied to the bottom of the right float (18) changes with this tilting, and if this pressure resists the spring (26), the working device 1i
(2) rotates to the left around the rolling axis (4) and becomes approximately parallel to the soil surface.

Moreover, the lifting mechanism (3) does not cause the fertilizer application device (6) to roll even if the left-right balance of the fertilizer application device (6) is disrupted due to the filling state of the spread fertilizer in the fertilizer application device (6) or the increase or decrease depending on the fertilization state. It does not affect the rolling action of the working device (2) and can always maintain parallelism with the soil surface.
