Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling planting machine with a fertilizer application device.

[0002]

2. Description of the Related Art As a conventional technique of this kind, there is a seedling planting machine provided with a fertilizer application tank and a feeding device above the wheels in order to improve the front-rear balance of the machine body. Since the feeding device is located above the wheels, the position of the center of gravity becomes high, which causes the traveling performance to deteriorate.

[0003]

In order to solve the above problems, the present invention is provided with left and right wheels 1 on both the left and right sides of a machine body 5, and inside the left and right wheels 1 and on the left and right outer sides thereof respectively when the machine body is viewed from the front. In a seedling planter provided with a seedling planting device 2a and an outer seedling planting device 2b, an inner fertilizer tank 3a, an inner feeding device 4a, and an inner fertilizer hose 13a for fertilizing the seedlings planted by the inner seedling planting device 2a. An outer fertilizer tank 3b, an outer feeding device 4b, an outer fertilizer hose 13b, and an outer grooving device 14 in order to fertilize the seedlings planted by the inner fertilizer application A including the inner grooving device 14a and the outer seedling planting device 2b.
and an inner fertilizer applicator A provided with an outer fertilizer applicator B consisting of
Inner feeding device 4a and outer feeding device 4 of the outer fertilizer applicator B
This is a seedling planting machine with a fertilizer application provided so that the left and right wheels 1 are respectively fitted between them.

[0004]

According to the present invention, the inner fertilizer application device A for fertilizing the seedlings to be planted by the inner seedling planting device 2a provided between the left and right wheels 1 in the front view of the machine and the outer side of the left and right wheels 1 in the front view of the machine. Since the outer fertilizer application device B for fertilizing the seedlings to be planted by the outer outer seedling planting device 2b is provided, each device can be arranged in the most appropriate state, and a small and lightweight seedling planter with a fertilizer application device can be obtained.

The inner feeding device 4a of the inner fertilizer applying device A
Since the left and right wheels 1 are provided so as to fit between the outer feeding device 4b of the outer fertilizer applicator B, the vertical height of the machine body can be configured to be low, and the center of gravity of the machine body can be lowered, and the running performance and operation of the machine body can be reduced. Workability improves and work performance improves.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A walk-behind fertilizer applicator seedling planting machine according to an embodiment of the present invention will be described in detail with reference to the drawings. The seedling planting machine is axially mounted at the rear ends of the chain cases 6 on the left and right of the machine body 5 so as to drive the left and right wheels 1. An interlocking case 7 is attached to the rear end of the machine body 5, and a base portion of a steering handle 8 extending rearward is connected to a lower portion of the interlocking case 7, and a seedling tank 9 is provided along the upper side of the steering handle 8. Is inclined rearward.
An inner seedling planting device 2a is attached to the central lower end of the interlocking case 7, and outer seedling planting devices 2b are attached to the lower ends of the left and right chain cases 10 provided on the left and right outer sides of the interlocking case 7, respectively. 2a and 2b are provided so as to face the lower end of the seedling tank 9, an inner seedling planting device 2a is provided between the left and right wheels 1 in a front view of the machine body, and an outer seedling planting device 2b is provided on the left and right outer sides of the left and right wheels 1. . A central float 11 and left and right side floats 12 are arranged below the interlocking case 7.

An inner fertilizer tank 3a and an outer fertilizer tank 3b are integrally formed on the upper portion of each of the left and right wheels 1 and fixed to the machine body 5. Then, at the lower part of the inner fertilizer tank 3a, the inner feeding device 4a and the inner fertilizer hose 13 are provided.
a is provided, and an outer feeding device 4b and an outer fertilizer hose 13b are provided below the outer fertilizer tank 3b. Each of the feeding devices 4a and 4b is configured such that a feeding roll (not shown) having a groove portion formed on the outer peripheral surface is rotated to adjust the width of the groove portion to be narrow or wide so that the fertilizer application amount is adjusted and the fertilizer is fed. I am trying.

Further, the lower ends of the inner fertilizer hoses 13a and the outer fertilizer hoses 13b are provided so as to be seen above the upper ends of the inner grooving device 14a and the outer grooving device 14b provided on the floats 11 and 12, respectively. There is. Inner fertilizer tank 3a above
The inner fertilizer A is composed of the inner feeding device 4a, the inner fertilizer hose 13a, and the inner grooving device 14a, and the outer fertilizer tank 3b, the outer feeding device 4b, the outer fertilizer hose 13b, and the outer grooving device 14b are used for the outer fertilizing device. Device B is configured. Then, the inner fertilizer application device A applies fertilizer to the seedlings to be planted by the inner seedling planting device 2a, and the outer fertilizer application device B performs fertilizer application to the seedlings to be planted. There is.

One-way clutches 15a, 15b for transmitting rotation in only one direction are provided on the delivery roll (not shown) shafts of each of the delivery devices 4a, 4b, and arms provided for the one-way clutches 15a, 15b. 16a, 16b
And the swinging cranks 17a, 17b of the seedling planting devices 2a, 2b facing below the feeding devices 4a, 4b are connected via connecting rods 18a, 18b, respectively.

When the left and right wheels 1 are driven and rotated, the machine body 5 runs and the seedlings in the seedling tank 9 are separated and planted by the respective seedling planting devices 2a and 2b. When each seedling planting device 2a, 2b is driven, each swing crank 17a, 17b swings, and each connecting rod 1
Each one-way clutch 15a, 15b via 8a, 18b
The arms 16a, 16b rotate up and down to intermittently rotate the feeding rolls, the fertilizers in the fertilizer tanks 3a, 3b are fed out, and the fed fertilizers are fed into the fertilizer pipes 13a,
It flows down in 13b, and is fertilized to the ditch | groove part made in the soil surface by each ditcher 14a, 14b. In this way, seedlings are planted while fertilizing.

In particular, since the inner fertilizer application A for fertilizing the seedlings planted by the inner seedling planting apparatus 2a and the outer fertilizing apparatus B for fertilizing the seedlings planted by the outer seedling planting apparatus 2b are provided. It is a small and lightweight seedling planting machine with fertilizer application, where each device can be placed in the most appropriate condition.
Further, since the left and right wheels 1 are provided so as to fit between the inner feeding device 4a of the inner fertilizer application A and the outer feeding device 4b of the outer fertilizer application B, the vertical height of the machine body can be made low and the machine body The center of gravity is low, running performance and operability of the machine are good, and work performance is excellent.
