Description

Detailed Description of the Invention The present invention has a plurality of seedling planting claws arranged side by side in the lateral direction of the machine body, a fertilizer tank, a feeding device for the fertilizer in the tank, and a fertilizer supply system by making a trench in the field and supplying fertilizer to the trench. The present invention relates to a rice transplanter with a fertilization device, which is provided with a fertilization device each having a plurality of fertilization portions in which the fertilization portions are arranged in parallel in the width direction of the machine body.

The above-mentioned rice transplanter is capable of direct sowing of rice, wheat, etc. by loading seeds instead of fertilizer into the fertilizer tank. In practice, it was not used for direct sowing operations because the spacing between the rows was different from that of conventional grains, making it difficult to harvest the mature grain culms with machinery.

An object of the present invention is to provide a rice transplanter with a fertilization device that is economically advantageous and that allows direct sowing operations to be performed.

The characteristic configuration of the present invention is that, in the rice transplanter with a fertilizing device described at the beginning, the fertilizing part is located near the seedling planting location by the seedling planting claw in the longitudinal direction of the machine body, and , are arranged with their positions slightly shifted to the same side in the width direction of the machine, and furthermore, the parallel pitches of the seedling planting claw and the fertilization part are configured to be the same, The action and effect are as follows.

That is, by setting the parallel pitch of the seedling planting claws and the parallel pitch of the fertilization part to be the same, the parallel pitch of the seedling planting claws is set to be the same as the row spacing set on the reaper. Seed can be sown so that the spacing between sowing rows is the same as the spacing between rows of the reaper. In addition, since the fertilizing part is offset laterally from the seedling planting area, there is less risk of chemical damage caused by the dropped fertilizer directly touching the roots of the planted seedlings, and the fertilizing part and the seedling planting area in the front and back direction are Since the distance between the seedlings and the seedlings is small, even when the aircraft meanderes, the risk of chemical damage caused by overlap between the dropped fertilizer and the seedling planting area is reduced.

Therefore, it is practically possible to use the method for direct sowing, and it is also possible to effectively apply fertilizer by dropping fertilizer near the planted seedlings while avoiding the risk of chemical damage caused by the application. Since the modification is as simple as changing the parallel pitch of the fertilization section, it has become possible to provide a convenient fertilization device at a low cost that can be used for direct sowing without any inconvenience.

Embodiments of the present invention will be described below based on the drawings.

As shown in Figures 1 and 2, four seedling planting arms 1 are arranged in parallel in the lateral direction of the machine, and each seedling planting claw 2 is equipped to be freely driven and movable so that it can rotate up and down. A seedling planting device 3 is connected via a link mechanism 4 to the rear of the wheeled traveling body so that it can be raised and lowered, and granular fertilizer stored in a tank 5 is supplied near each seedling planting location. A fertilizing device 6 is provided on the seedling planting device 3 to constitute a riding rice transplanter that can perform fertilization work while planting the seedlings.

Line marker 7 is placed on both the left and right sides of the traveling aircraft.
is provided so as to be freely switchable between a lowered use position and a raised storage position, and when traveling, a traveling target line is formed in the field by the marker 7, and when traveling back, the marker 8 is aligned with the target line while traveling. By doing so,
It is designed so that the work can be done while keeping the distance between the planted shoots constant.

As shown in FIG. 3, the fertilizer application device 6 includes four fertilizer delivery devices 9 attached to the lower part of the fertilizer tank 5, and fertilizer is supplied to these delivery devices 9 through a hose 10. Four gutter-like fertilizing parts 11... each connected separately so as to be arranged in a parallel pitch.
P ₁ is the same as the parallel pitch P ₂ of the seedling planting claws 2, and one fertilizing part 11 is located slightly in front of each of the seedling planting claws 2 on the same lateral side in the width direction of the machine. The fertilizing section 11 forms a groove in the field as the machine travels, and fertilizer is supplied to the groove.

A manual adjustment part 13 is provided between the seedling planting device 3 and the link mechanism 4 to slide and change the connection position of the seedling planting device 3 in the width direction of the machine body, and seeds such as rice and wheat are loaded into the fertilizer tank 5. When performing direct sowing work, or placing pine-shaped fertilizer on the seedling stand 14, and performing fertilization work in conjunction with direct sowing,
As shown in Fig. 2, the connection position of the seedling planting device 3 is adjusted so that the horizontal center X of the four rows of sowing rows A coincides with the horizontal center of the traveling machine, and the line drawing marker 7 and the index 8 are adjusted. The structure is such that it is easy to work while keeping the distance between sowing rows constant.

A clutch (not shown) is provided to stop only the mechanism (not shown) that reciprocates the seedling tray 14 left and right, and when only direct sowing is performed, the left and right movement caused by the left and right sliding of the seedling tray 14 is prevented. The seedling stand 14 is configured to be stopped at a position with good weight balance so as not to cause the weight to become unbalanced.

As shown in FIGS. 3 and 4, each of the fertilizer dispensing devices 9 includes a dispensing rotary body 17 consisting of a first rotary body 15 and a second rotary body 16.
is rotatably attached to the feeding case 19 via a spindle 18 that rotates integrally with the seedlings, and the rotating spindle 18 is reciprocated by a certain angle by the driving force of the seedling planting arm 1. Linked to the planting arm 1, the rotating body 17 is reciprocated by a certain angle, and the fertilizer in the tank 5 is transferred to the first rotating body 15.
A predetermined amount is taken out through the recess 20 and supplied to the hose 10 via the feeding case 19.

A cylindrical shaft 21 that is internally screwed into the second rotating body 16
is externally fitted onto the support shaft 18 so as to be relatively rotatable, and the cylindrical shaft 21 is rotated using the operating section 22, whereby the recessed portion 16a of the second rotary body 16 relative to the recessed portion 20 rotates relative to the first rotation. As the body 15 slides, the volume of the recessed part 20 changes, and the amount of delivery changes.

A scale 23 is provided on the circumferential surface of the cylinder shaft 11 for displaying the amount of change in the feeding amount due to the operation of the cylinder shaft 21 based on the amount of displacement of the boss portion edge 16b of the second rotating body 16 with respect to the cylinder shaft 21, Further, a scale 25 is provided on the circumferential surface of the operating section 22 for displaying minute changes in the amount of delivery due to the operation of the cylinder shaft 21 based on the rotation angle of the operating section 22 with respect to the spring plate stopper 24. The stopper 24 is for preventing the feeding rotating body 17 from sliding with respect to the support shaft 18 via the cylindrical shaft 21.

Note that the present invention can also be applied to a walking rice transplanter.

Further, although reference numerals are written in the claims section for convenience of comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings by the reference numerals.
