Description

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 an actual exploitation 57
As shown in Japanese Patent Publication No. 82124, in a seedling planting machine provided with an inner seedling planting apparatus and an outer seedling planting apparatus for planting seedlings between the left and right wheels and the left and right outer sides thereof in a front view of the machine body, the front and rear balance of the machine body is improved. In order to do so, there is a seedling planting machine with a fertilizer application, which is provided with a fertilizer application near the left and right wheels.

[0003]

However, in the above-mentioned prior art, since the feeding device is provided at the outer position of the left and right wheels to fertilize the seedlings planted by the inner seedling planting device, the wheels disturb the feeding. Since the device had to be installed at a relatively high position, the weight of the machine was high and the running stability was poor. However, the fertilizer hose had to be provided around the wheel from the feeding device to the fertilizer application position for the seedlings planted by the inner seedling planting device, and the fertilizer clogging occurred frequently, resulting in poor work efficiency.

[0004]

In order to solve the above problems, the present invention provides an inner seedling for planting seedlings between the left and right wheels 1 provided on the left and right sides of the machine body 5 in front view of the machine body and on the left and right outer sides thereof. In a seedling planting machine provided with a planting device 2a ... and an outer seedling planting device 2b ..., an inner fertilizer applying device A for fertilizing the seedlings planted between the left and right wheels 1 and a fertilizing fertilizer for seedlings planted outside the left and right wheels 1. An outer fertilizer application device B is provided, and the inner feeding device 4a of the inner fertilizer application device A is driven by interlocking with the inner seedling planting device 2a provided between the left and right wheels 1. This is a seedling planting machine with a fertilizer application that is driven in conjunction with an outer seedling planting device 2b provided outside the left and right wheels 1.

[0005]

Since the present invention is configured as described above, the inner feeding device 4a and the outer feeding device 4b can be arranged lower than those of the prior art, and the body center of gravity can be lowered and the running performance and the body can be reduced. The operability is improved and the work performance is improved. Of course, the inner fertilizer application A for fertilizing the seedlings planted between the left and right wheels 1 is provided between the left and right wheels 1, and the outer fertilizer application B for fertilizing the seedlings planted outside the left and right wheels 1 is outside the left and right wheels 1. The fertilizer hose can be shortened and the clogging of fertilizer application can be reduced to improve the work efficiency.

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 to drive the left and right wheels 1 at the rear ends of the chain cases 6 on the left and right of the machine body 5. 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.
The inner seedling planting device 2a is attached to the center lower end of the interlocking case 7, and the 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. . Below the interlocking case 7, a central float 11 and left and right side floats 12 are arranged in parallel.

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. The inner fertilizer hose 13a and the outer fertilizer hose 13
b is provided in a steep slope so that the occurrence of clogging of fertilizer is reduced. In addition, in each of the feeding devices 4a and 4b, a feeding roll (not shown) having a groove portion formed on the outer peripheral surface is rotated, and the width of the groove portion is adjusted to be wide or narrow to adjust the fertilizer application amount,
Fertilizer is fed out.

Further, the lower ends of the inner fertilizer hoses 13a and the outer fertilizer hoses 13b are provided at 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 outer fertilizing. Device B is configured. 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 each one-way clutch 15a, 15b. 16a, 16b
The swinging cranks 17a and 17b of the seedling planting devices 2a and 2b facing below the feeding devices 4a and 4b are connected via connecting rods 18a and 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 roll, the fertilizer in the fertilizer tanks 3a, 3b is fed, and the fed fertilizer is fed to the fertilizer pipes 13a,
It flows down in 13b, and is fertilized to the groove part formed on the soil surface by each of the groovers 14a and 14b. In this way, seedlings are planted while fertilizing.

Since the inner feeding device 4a and the outer feeding device 4b can be arranged lower than the upper ends of the left and right wheels 1, the fertilizer tanks 3a and 3b can also be configured to be low, and the body weight as a whole is low, and the running performance is low. Also, the operability of the machine is improved and the work performance is improved. Of course, the inner fertilizer application A for fertilizing the seedlings planted between the left and right wheels 1 is provided between the left and right wheels 1, and the outer fertilizer application B for fertilizing the seedlings planted outside the left and right wheels 1 is outside the left and right wheels 1. Since the fertilizer hose is provided at the position, the fertilizer hose can be arranged in a short shape with a steep slope close to vertical, and good fertilization work can be performed with less occurrence of clogging of fertilizer.
