A suitable fertilizer tank mounting structure is provided, in which the fertilizer tank is installed under the canopy sheet covering the aircraft control section and above the rear of the control section so that it can be pulled down to the fertilizer replenishment position. The main purpose of this invention is to facilitate the replenishment of seedlings to the above-mentioned seedling planting machine, and
The purpose is to constantly and stably supply fertilizer to a fertilizer embedding device equipped on the seedling planting machine without being hindered by the vertical movement of the seedling planting machine.

とになつていた。 That is, in general, a riding type rice transplanter has a seedling planting machine connected to the rear of the machine, while storing spare seedlings on the bonnet side of the front part of the machine, and the seedlings on the side of the seedling planting machine are stored during rice planting work. As the number of seedlings decreases from the platform, the operator is able to replenish the platform with spare seedlings at any time. Therefore, planting of seedlings and fertilization are often carried out simultaneously. In this case, the fertilizer tank of the fertilizer applicator is mounted on the aircraft, and the fertilizer embedder is attached to the seedling planting machine, and both are connected by a fertilizer supply hose, but normally the fertilizer tank is located behind the control section. Because it is mounted protrudingly on the upper surface of the fuselage at the back, when the operator tries to supply spare seedlings to the seedling planting machine, the fertilizer tank does not interfere with the replenishment operation, making it possible to quickly and orderly feed the spare seedlings. In addition, because the head difference between the fertilizer tank and the fertilizer embedder is relatively small, when the depth of the plowing bed increases and the seedling planting machine rises relative to the machine body, the head difference further decreases. However, not only is it not possible to stably supply fertilizer to the fertilizer embedding device, but the fertilizer supply hose becomes bent or bent due to slack, and in the worst case scenario, the fertilizer supply would stop.

具３４が固着されている。 Hereinafter, an embodiment of the present invention will be explained based on the drawings. Fig. 1 shows a riding rice transplanter, in which a pair of front wheels 2 and a pair of rear wheels 3 on the left and right sides are mounted on the machine body 1 as a traveling device. The upper part is used as a control section 4 and is equipped with a control seat 5, a handle 6, various control levers 7, etc., and an engine 8 is mounted in front of the control section 4. A spare seedling storage rack 9 is attached, and a canopy frame 11 supported by struts 10 is disposed on the top of the control section 4.
A sunshade/rainproof hood sheet 12 covering directly above the control section 4 is attached to 1. On the other hand, a seedling planting work machine 14 is connected to the rear of the machine body 1 via a lifting link mechanism 13, and a drive device 16 that receives power from the machine body 1 side via an input shaft 15 to the work machine 14; A seedling platform 17 that is laterally reciprocated by a drive device 16, a planting claw mechanism 18 that is also driven by a drive device 16, etc. are integrally equipped, and a seedling planting work machine 14 is moved by a float 19. It is held on the planting mud surface. The fertilizer application device 20 also includes a fertilizer tank 21, a fertilizer embedding device 22 that also serves as a trencher,
and a fertilizer feeding hose 24 that communicates and connects a fertilizer feeder 23 installed at the bottom of the fertilizer tank 21 and a fertilizer embedding section 22, and the fertilizer embedding section 22 is attached to the front end of the float 19, and A tank 21 is attached to the fuselage 1 side below the hood sheet 12 and above the rear of the control section 4. That is, a movable arm 26 that moves up and down about a support shaft 25 is supported at the upper end of the support 10 for the hood sheet, and a torsion bar mechanism using a helical spring or the like is attached to the support shaft 25 (Fig. (not shown), the movable arm 26 is pulled up and biased by the spring force to the approximately horizontal raised position shown in the solid line position in FIG. 28 is lowered, and the engaging pin 30 at the tip of the movable arm 26 is loosely engaged with the horizontal guide elongated hole 29 provided in the side wall of the fertilizer tank 21. Engagement pin 3
1 is loosely engaged with the guide elongated hole 27 of the vertical rod 28,
Thus, the fertilizer tank 21 is suspended from the movable arm 26 and the vertical rod 28, and can be pulled down against the spring force. 32
is a latch installed on the fertilizer tank 21, and when not in use, the latch 32 is engaged with a hook fitting 33 also fixed to the fertilizer tank 21, and a stopper fitting corresponding to the latch 32 is provided on the upper surface of the machine body 1. 34 is fixed.

弛みがなく、故に該ホース２４の彎曲変形もしく
は屈曲変形もほとんど生じなくなる。 In the case of a rice transplanter having such a configuration, as is well known, the operator is seated on the control seat 5, the rice transplanter 1 is running with spare seedlings stored in the spare seedling storage rack 9, and the rice transplanter is used for planting. The claw mechanism 18 is the seedling stand 17
Seedlings are taken out one by one and planted. On the other hand, the fertilizer feeder 23 works, and a fixed amount of fertilizer is supplied from the fertilizer tank 21 to the fertilizer embedding device 22 through the fertilizer feeding hose 24, and the seedlings are planted. Fertilization work and fertilization work are carried out in parallel. However, during this seedling planting work and fertilization work, the fertilizer tank 21 is placed in the position of the canopy sheet 1 as shown in the solid line position in Figure 1.
2, a large head difference is formed between the fertilizer tank 21 and the fertilizer embedding device 22, and this large head difference is used to keep the fertilizer embedding device 22 stable at all times. fertilizer is supplied. In addition, since the seedling planting working machine 14 is raised and lowered relative to the machine body 1 according to the depth of the plow and using the lifting link mechanism 13, the seedling planting working machine 1
4, the fertilizer supply hose 24 becomes slack and a bending or bending force acts on the hose 24, and the fertilizer supply is about to be stopped. 22 is said to be large compared to the amount of elevation of the seedling planting machine 14, so there is no slack in the fertilizer feeding hose 24, and therefore there is almost no bending or bending deformation of the hose 24. It will no longer occur.

なうことができる。 Furthermore, as the seedlings on the seedling platform 17 gradually decrease as the seedling planting work progresses, the operator takes out the spare seedlings from the spare seedling storage rack 9 and replenishes the seedling platform 17 with them. be. However, as mentioned above, the fertilizer tank 21 is in the raised position and is kept clear behind the control section 4, so the operator can place the spare seedlings on the seedling platform 17 without being obstructed by the fertilizer tank 21. Moreover, when the fertilizer tank 21 is pulled down along the vertical rod 28 and the latch 32 is engaged with the stopper fitting 34 to lock it in the position shown in chain lines in FIG. It can be done at any location.

るのが望ましい。 FIGS. 2 and 3 show an example of a fertilizer feeding hose 24 used in the fertilizer application device 20. FIG. The hose 24 includes an upper hose 35 connected to the lower outlet 23a of the fertilizer feeder 23;
The lower hose 36 is connected to the socket 22a of the fertilizer embedding device 22.
A bellows part 37 is formed at the upper end of the bellows part 3.
7 is fitted onto the upper hose 35. With this structure, when the seedling planting machine 14 moves up and down as described above, the elastic force acting on the fertilizer feeding hose 24 is absorbed by the elastic movement of the bellows part 37 shown in FIGS. 2 and 3. Therefore, the fertilizer feeding hose 24
This is preferable because it does not cause loosening or excessive tensile force. In addition, the tip 36a of the lower hose 36 is connected and fixed to both hoses 35 and 36, so
In order to prevent rainwater from entering, it is necessary to be elastically tied to the upper hose 35. Therefore, it is desirable that the lower hose is made of a highly elastic synthetic resin pipe.

蛇腹部３７において吸収できるのである。 That is, as described at the beginning, when the seedling planting machine 14 is raised and lowered according to the depth of the tiller, an elastic force acts on the fertilizer feeding hose 24. When the hose consists of a single pipe, especially the seedling planting machine 1
4, the hose becomes slack, and the deformation of the hose impedes the supply of fertilizer. Therefore,
Attempts have also been made to use a bellows hose or a retractable hose consisting of a double pipe as the fertilizer feed hose, but with the former, fertilizer adheres to and accumulates in the internal folds of the bellows hose, and with the latter, it leaks from the connection of the double pipe. Both are unsuitable for practical use because rainwater and mud can enter them. However, according to the configurations shown in FIGS. 2 and 3, the elastic binding force of the tip 36a prevents rainwater and mud from entering, and even when the bellows portion 37 is extended as shown in FIG. By preventing the fertilizer from protruding beyond the lower end, the fertilizer will not stick to the bellows part 37 and the elastic force acting on the hose 24 can be absorbed by the bellows part 37.

作業は通常通り遂行できるものである。 FIG. 5 shows a configuration in which a fertilizer embedding device (hereinafter referred to as a furrowing device) 22 is displaced in response to the raising and lowering of the seedling planting machine 14. In other words, in the case of a rice transplanter, the groove cutter 22 is integrally and fixedly attached to the tip of the float 19, and during seedling planting work, the groove cutter 22 protrudes below the float 19, as shown in FIG. It sinks into the planting mud surface A, thereby creating a fertilization groove. Therefore, when the machine body 1 turns at the end of the seedling planting line, large soil resistance acts on the furrower 22, causing the furrower 22 to rotate.
Not only will this damage the seedling planting device 14, but a large load will be applied to the seedling planting machine 14. Therefore, it is desirable to lift the groove cutting device 22 above the lower surface of the float 19 and pull it out from the planting mud surface A during the turning. By the way, in the configuration shown in FIG.
The bell crank 40 rotates around the pin 39.
At the same time, the lifting link mechanism 13
One end of the connecting rod 41 is pivotally connected to the connecting rod 41 by a pin 42, and the connecting rod 41 and the bell crank 40 are connected by the engaging pin 4.
3 and an elongated hole 44 through an engagement structure. In this way, in the seedling planting operation state, the furrower 22 protrudes below the float 19 and sinks into the planting mud surface A, but when the seedling planting machine 14 is raised during turning, the connecting rod 41 is moved by the bell crank. 40 and rotate it, and the groove creator 22 is lifted upward around the pin 39, and the groove creator 22 is pulled out from the planting mud surface A. The reason why the elongated hole 44 is used to connect the connecting rod 41 and the bell crank 40 is that the connecting rod 41 rotates the bell crank 40 in the rotation direction after the seedling planting machine 14 has been raised by a certain amount. This is to allow the groove to be poked, and therefore, the groove creator 2 is
2 can be kept in the normal position as shown in Fig. 4, so even if the height of the seedling planting machine is changed according to the depth of the plowing platform, the furrowing movement and fertilization work by the furrower 22 can be maintained easily. It can be carried out normally.

ホースを通す肥料供給を妨げることがない。 As described above, the present invention provides a riding type agricultural tractor equipped with a fertilizer application device, in which the fertilizer tank of the fertilizer application device is placed under the canopy sheet that covers the aircraft control section and at a position above the rear of the control section for replenishing fertilizer. Since it is attached so that it can be pulled down to the desired position, when the seedling planting machine is connected to the rear of the agricultural tractor for rice planting, the operator can replenish the seedlings to the seedling planting machine into the fertilizer tank. This can be done quickly and easily without any hindrance, and by placing the fertilizer tank in the upper position, a large head difference can be created between the fertilizer tank and the fertilizer embedder installed on the seedling planting machine. This allows for a stable and reliable supply of fertilizer to the fertilizer embedding device, and due to the large head difference mentioned above, even if the seedling planting machine is raised and lowered according to the depth of the tiller, the fertilizer supply hose cannot be used. The bending deformation and bending deformation due to the slackness of the hose is reduced or suppressed, and the supply of fertilizer through the hose is not obstructed.
