And each blower 36, 36 is communicated with the lower part of the measuring part 38 of each fertilizer applicator body 30 through a blower pipe 37 formed of a flexible material such as rubber or soft plastic which can be expanded and bent. I have.

As shown in FIG. 3, each fertilizer applicator body 30 has a weighing section 38 connected to the lower end of a substantially funnel-shaped hopper 39,
Connect the upper end of fertilizer hose 40 to the lower end of 38
A groove generator 41 is connected to the lower end of 40, and a blower 36 is
The blower pipe 37 connected to the
A drive shaft 44 for driving the measuring section 38 is linked to a crank 42 linked to the hopper 39 via a link mechanism 43 capable of changing the output stroke and a one-way clutch (not shown). The measured fertilizer is weighed by the weighing unit 38, and the weighed fertilizer is put on the carrier air from the blower 36 sent through the air pipe 37, and is sent to the groove generator 41 via the fertilizing hose 40. Like that. In the figure, 45 is a support frame,
46 is a weighing adjustment mechanism.

Therefore, the sub-frame 32 is expanded sideways to
It enables side fertilizer application for 0 rows and the sub-frame 32
Can be stored inside the front for easy transportation.

The opening 47 of each hopper 39 is formed in a substantially rectangular shape, and is closed by a lid 50 that can be freely opened and closed.

As shown in FIGS. 2 to 7, the lid 50 is provided with two lids 50 for closing the four hoppers 39 on the main frame 31 side.
One lid 50 for closing the two hoppers 39 is disposed on the sub-frame 32 side, and the lid 50 on the main frame 31 side is disposed.
The cover 50 on the side of the sub-frame 32 and the cover 50 on the side of the sub-frame 32 are different from each other only in the length in the left-right direction.

That is, as shown in FIGS. 4 to 6, the lid 50 is formed by a lid central portion 51 and a lid end portion 52 connected to the left and right sides of the lid central portion 51. The lid central portion 51 has a substantially rectangular plate shape in a plan view, and has a lip 53 bent downward at front and rear side edges, and a plurality of reinforcing ribs 54 extending left and right on the lower surface, The lid end 52 is composed of an upper surface plate 55 and front and rear side plates 56.
And an outer end face plate 57, and a receiving hole 58 corresponding to the lip 53 and the reinforcing rib 54 is formed at an inner edge of the upper face plate 55 and the front and rear side plates 56, and a rear end of the outer end face plate 57 is formed. A support shaft insertion hole 59 is formed in the portion, and a support shaft 60 formed on the outer surface of the opening 47 of the hopper 39 is rotatably inserted into the support shaft insertion hole 59,
The lid 50 can be opened and closed around the support shaft 60. In the figure, 61 is a handle, and 62 is a toggle latch.

In particular, in this embodiment, as shown in FIGS. 6 and 7, a stopper rib 63 extending in the left-right direction is protruded in the vicinity of the rear end edge of the lower surface of the lid center portion 51.
A thick sealing material 64 made of a flexible material such as a sponge is adhered to the outer surface of 63, and when the lid 50 is opened, the sealing material is
The fertilizer in the hopper 39 is prevented from spilling when the lid 50 is opened and closed by pressing the upper end 64 of the opening 47 of the hopper 39 against the upper end edge 65 of the hopper 39.

FIG. 8 shows a stopper rib 66 of another embodiment. An auxiliary rib 67 extending inward is connected to the lower end edge of a stopper rib 63 having the same shape as that described above, and the lid 50 is opened. At this time, the upper surface of the auxiliary rib 67 abuts on the rear upper edge 65 of the opening 47 of the hopper 39, and the sealing material 64 is pressed against the outer surface of the upper end of the rear of the opening 47 so that the lid 50 The fertilizer in the hopper 39 is prevented from spilling at the time of opening and closing. In this embodiment, the fertilizer in the hopper 39 does not adhere to the sealing material 64, so that the effect of preventing the spillage of the fertilizer can be enhanced.

FIG. 9 shows a support 70 for the seedling mounting table 23 and the fertilizing hose 40 disposed on the back surface thereof. The support 70 is, as shown in FIG. On the surface, two substantially U-shaped holding tools 72 for holding the fertilizing hose 40 are erected,
Bolts 73 projecting toward the seedling mounting table 23 are provided upright at both ends of the substrate 71, and the support 70 is fixed to the back surface of the seedling mounting table 23 via the bolts 73.

FIG. 11 shows a support 75 according to another embodiment, in which holding members 72 having the same shape as above are provided on the outer surfaces of the left and right ends of a substantially U-shaped substrate 76 opened forward. Set up
Through a mounting portion 77 protruding from the center of the back surface of the substrate 76,
75 is fixed to the back surface of the seedling mounting table 23.

FIG. 12 shows the cleaning status of the fertilizer hose 40. The cleaning hole 80 at the bottom of the fertilizer main body 30 is opened, and the
Remove the end of the fertilizer hose 40 from 41, and insert the cylindrical brush 82 attached to the tip of the long flexible shaft 81 from the opening at the same end, so that the fertilizer hose 40 and the fertilizer
30 to make sure the bottom and inside are cleaned.

[0027]

According to the present invention, the following effects can be obtained.

According to the first aspect of the present invention, the lid is attached so as to be openable and closable about a support shaft provided at one side edge of the hopper,
A stopper rib protrudes from the lower surface of the lid parallel to the support shaft, and a sealing material made of a flexible material is fixed to the side of the stopper rib facing the support shaft, and the opening of the hopper is opened when the lid is opened. Since it is configured so as to be pressure-bonded to the first side edge, it is possible to prevent the fertilizer in the hopper from spilling when the lid is opened and closed.

According to the second aspect of the present invention, a sealing member made of a flexible material is fixed to a side surface of the stopper rib facing the support shaft, and an auxiliary rib protruding in the support shaft direction is protruded from an end edge of the stopper rib. When the lid is opened, the auxiliary rib abuts on the outer edge of the opening of the hopper, and the sealing material is configured to be pressed against the outer surface of the upper end of the opening. Is prevented from adhering to the sealing material, and the effect of preventing spillage of fertilizer can be reduced.
