Reference numeral 1 denotes a running vehicle body of a fertilization device, and running frames 2 in the front and rear direction are arranged side by side on both left and right sides. Reference numeral 3 denotes a support leg hanging from the running frame 2, and a single-wheel drive wheel 4 is mounted between the left and right support legs 3 via a shaft 5.

Reference numeral 6 denotes an engine provided at the front upper part of the traveling frame 2, 7 a walking control handle provided at the rear end of the traveling frame 2, 8 a fuel tank, and 9 a sprocket and chain for transmitting the rotation of the engine 6 to the transmission 10. A built-in transmission case 11 is a transmission case that transmits rotation from the mission 10 to the shaft 5.

Engagement shafts 12 are provided on the outer side of the support legs 3 of the traveling vehicle body 1 and project outwardly on both the left and right sides. A support fitting 13 is provided at the rear of the running frame 2, and a left-right engagement shaft 14 projecting inside the running frame 2 is rotatably attached to the support fitting 13 so as to be freely removable and removable. 15 is an operating lever for moving the engagement shaft 14 in and out.

16 is a fertilization section attached to the traveling vehicle body 1. That is, the fertilization section 16 has a left fertilization section 20a and a right fertilization section 20b fixed together by a connecting rod 22 and a communication arm 31 to form the entire approximately shape.
The traveling vehicle body 1 is positioned between the right fertilizing part 20b and the right fertilizing part 20b.

Vertical rods 21 in the front-rear direction are attached to the left and right sides of the connecting rod 22 and the communication arm 31, respectively, and a left fertilizer tank 17a and a right fertilizer tank 17b are attached to the outer side of each vertical rod 21. Left fertilizer tank 1
7a and the right fertilizer tank 17b are the standing plants 41 in the field.
The erect plants are placed between the rows or above the rows in a separated state (Figure 4).

The rear end of the vertical rod 21 is fixed to a connecting rod 22 in the left-right direction, and on both left and right sides of the connecting rod 22, a left fertilizer application section 20a is provided at the rear of the left fertilizer tank 17a, and a right fertilizer application section 20b is installed at the rear of the right fertilizer tank 17b. Form it so that it is located. The upper end portions of a vertical transmission case 23 are fixed to both ends of the connecting rod 22, respectively. A fertilizer feeding pump 18 is provided on the outer surface of the left transmission case 23 and the outer surface of the right transmission case 23, respectively. The left fertilizer tank 1 is located in front of the left fertilizer feeding pump 18.
7a, and a fertilization pipe 24 connected to the left fertilization nozzle 19 is attached to the rear side. The right fertilizer tank 17b is connected to the front side of the right fertilizer delivery pump 18, and the fertilizer feeding pipe 24 connected to the right fertilizer nozzle 19 is attached to the rear side.

A drive shaft 26 is provided at the lower end of the transmission case 23 so as to protrude to the left and right sides, a large diameter drive wheel 25 is provided on each outer side of the drive shaft 26, and a small diameter drive wheel 25 is provided on each inner side of the drive shaft 26. ′ are respectively fixed.
27 is a drive gear fixed in the middle of the above-mentioned 26, and the above-mentioned drive shaft 26 is inside the upper connecting rod 22.
A passive shaft 28 corresponding to the drive gear 27 is provided, and a passive gear 29 corresponding to the drive gear 27 is fixed to both ends of the passive shaft 28. Each drive gear 27 and each passive gear 29 are connected by a chain 30, and the aircraft moves. Then, the rotation of the large-diameter drive wheel 25 and the small-diameter drive wheel 25' rotates the passive shaft 28, and the rotation of the passive shaft 28 drives the left and right fertilizer delivery pumps 18, respectively.

A type of communication arm 31 is provided on the front side of the connecting rod 22, and the upper ends of vertical parts 40 protruding downward are fixed to both ends of the horizontal part 39, and the left side is attached to the outside of each of the vertical parts 40. Fix the vertical rod 21 and the right vertical rod 21. A two-straddle portion 32 is provided at the lower end of each of the vertical portions 40, 40 in the front-rear direction, and the two-straddle portion 32 is engaged from above with the engagement shaft 12 provided on the support leg 3 of the traveling vehicle body 1. The fertilizing section 16 is then fixed rotatably with the pin 33, and the fertilizing section 16 is attached to the traveling vehicle body 1.

Thus, the horizontal portion 39 acts as a scraper for scraping off the adhered mud when the drive wheel 4 rotates. 34 is an engagement plate, which is formed parallel to the traveling vehicle body 1, and the engagement plate 34 has engagement holes 35 in the left and right direction.
are provided above and below. The engagement shaft 14 of the traveling vehicle body 1 is engaged with the engagement hole 35 .

36 is a groove-making blade provided in front of each fertilizing nozzle 19; 37 is a rotary blade provided in front of the groove-making blade 34;
8 is a sled body.

(effect) Next, we will discuss the effect.

When the engine 6 is started, the walking steering handle 7 is supported, and the driver moves forward, the drive wheels 25, 25' rotate.
The rotation of the drive wheel 25 is transmitted through the drive shaft 26 → drive gear 27 → chain 30 → passive gear 29 → passive shaft 28, and operates the fertilizer delivery pump 18, and the fertilizer in the left fertilizer tank 17a and right fertilizer tank 17b is Each of the fertilizers is fed by the fertilizer delivery pump 18 to the fertilizer application nozzle 19 through the fertilizer delivery pipe 24, and is applied into the grooves formed deep into the soil by the rotary blade 37 and the groove-making blade 36.

At this time, since the left fertilizer tank 17a and the right fertilizer tank 17b are located above the rows of the standing plants 41 in the field (Fig. 4), the left fertilizer tank 17a and the right fertilizer tank 17b move forward while weeding the upper ends of the standing plants 41. can do. Therefore, it is very easy to move forward and perform fertilization work, and the standing plants 41 are not trampled over.

(Effects) As mentioned above, there is a known device in which a fertilizer tank is provided in the upper part of the one-wheeled vehicle body, and the fertilizer in the tank can be applied by a fertilizer application section having a fertilizer delivery pump, a fertilizer application nozzle, a rotary blade, etc. be. However, conventional fertilization devices have problems in separating the standing plants because they apply fertilizer by moving between the standing plants in a paddy field.

However, in the present invention, the left fertilizer tank 17a and the right fertilizer tank 17b are provided at positions where the standing plants 41 can be separated between the rows on both the left and right sides of the drive wheel 4 of the single-wheeled traveling vehicle body 1, or above the rows, and The left fertilizer tank 17a and the right fertilizer tank 17 are configured as a deep fertilization device for paddy fields, with a left fertilizer application section 20a provided at the rear of the fertilizer tank 17a, and a right fertilizer application section 20b provided at the rear of the right fertilizer tank 17b.
Since b is located between the rows, it is difficult to damage the standing plants, and since it is targeted between the rows, the forward visibility is good.
This has the effect of making driving easier.
