The hopper 30 is provided so as to have the same number of fertilizer application lines as the number of planting lines, whereas the hopper 30 is long and integrally provided on the left and right sides so as to be able to accommodate a large amount of fertilizer. I have. Since the integrated hopper 30 can be constituted by connecting a single hopper 30 '... left and right by the number of fertilizing strips, the hoppers 30 having different numbers of fertilizing strips can be constituted by a combination of single hoppers 30' ... cost. Down can be achieved. The main body of the single strip hopper 30 ′ includes front and rear side walls 30 ′.
a, 30'a, side walls 30'b, 30'b which are opened to the left and right and concavely cut out, and funnel-shaped front, rear, left and right inclined surfaces 30'c, 30'c, 30'd on the bottom side. , 30'e (3
0'd is a steeply inclined surface and 30'e is a gently inclined surface). The upper open part is the fertilizer input port 30a, and the lower square hole is the fertilizer discharge port 30b. The position of the fertilizer discharge port 30b is provided to be shifted left and right (to the side of the steeply inclined surface 30'd) in plan view. The single hoppers 30 'are integrally formed by connecting rivets so that the left and right side walls 30'b, 30'b cut into the concave strips are in contact with each other for the number of fertilizing strips. . Further, here, the front and rear side walls 30′a... 30′a.
The front and rear outer plates 30'f, 30'f are attached to the outer surface of the left and right sides of the same width and the upper and lower sides are wider than the side wall vertical width. Left and right outer plates 30′g so as to cover the concave cutouts on the outer side surface,

6A, 6B, 7C, and 7C, the hopper 30 is integrally connected according to the number of fertilizer strips.
(D) As shown in FIG.
... are connected. In the figure, the hopper portion is a schematic diagram in plan view, and the position of the hopper 30 (the center of the fertilizer discharge port 30b ...), the planting position P ..., and the fertilizing position (laterally shifted from the planting position P due to lateral fertilization). FIG. 7 is a diagram showing the positional relationship with F. FIG. 6A shows the case of the four-row planting type, and FIG. 6B shows the case of the five-row planting type.
FIG. 7C shows the case of the six-row planting type, and FIG. 7D shows the case of the eight-row planting type. In each figure, each fertilizer outlet 30
The fertilizing hoses 32 for each strip are led out from the center of b. The hopper 30 is configured so that the fertilizing hoses 32 are arranged to the fertilizing position F without shifting left and right. In addition, the steeply inclined surfaces 30'd are connected so as to be adjacent to each other as much as possible, and the connecting portions of the steeply inclined surfaces 30'd are arranged at the right and left center positions C of the fuselage as much as possible. 30s is a fertilizer reduction sensor, which is all attached to the steeply inclined surface 30'd. With the above configuration, the hopper 30 is operated.
The fertilizer rice transplanter arranged behind the seat 9 and in front of the planting section 4 is particularly effective in a hopper connection configuration in the case of 5-row planting and 6-row planting. That is, when removing the fertilizer remaining in the hopper on the center side, the cockpit 9 is in front of the hopper and there is no space for taking out the fertilizer, so that the fertilizer is moved into the hoppers on the left and right sides and removed from the left and right sides. However, in this case, particularly, in the case of the five-row planting and the six-row planting, the hopper 30 can move the fertilizer on the gentle slope 30′e on which the fertilizer reduction sensor 30s is not attached, so that the center side is moved. It is configured so that it is easy to take out the fertilizer (when the fertilizer is to be moved on the steeply inclined surface 30'd, the inclination is steep and it is difficult to move, and the fertilizer reduction sensor 30s attached to that surface It is hard to do it.)

Further, a funnel-shaped front, rear, left and right inclined surfaces 30'c, 3 'provided on the bottom side of each single hopper 30'.
Due to 0'c, 30'd, and 30'e, the fertilizer contained in the hopper 30 naturally slides down toward the supply ports 31c of the feeding sections 31 connected to the fertilizer discharge ports 30b of the hopper 30. It has become. When the lid 30c is opened and fertilizer is supplied, a band-shaped sheet 30c 'for preventing accumulation of fertilizer is formed on the rear side of the hopper inner wall and on the inner pivot side of the lid 30c so that the fertilizer does not accumulate on the lid 30c pivot side. Affixed.

The front and rear outer plates 30'f, 30'f
Are located at the lower end positions of the inclined surfaces 30'c, 30'c, 30 '.
The upper and lower widths are widened so as to be positioned below the inclined upper positions d and 30′e. That is, there are provided skirt portions 30d, 30d that hang downward from the upper side of the inclined surface without being parallel to the inclination of the inclined surface 30e. Thus, water droplets adhering to the outer surface of the hopper 30 do not permeate the inside of the feeding portion from the connection portion with the feeding portion 31 on the inclined surfaces 30'c, 30'c, 30'd, 30'e. . Therefore, fertilizers troubles that fertilizer clogging attached by absorbing moisture occurs can be prevented by the feeding portion within 31.

It operates to store and turn the fertilizer inside and drop the fertilizer in the ditch below. During the rotation, the fertilizer in the groove is constantly fed out by a brush 31f attached so as to be in contact with the outer peripheral surface of the feeding roll 31b. The brush 31f can be easily taken out by opening the lid 31a 'provided on the front side surface of the feeding part case 31a. At this time, as the lid 31a 'is opened, the fertilizer take-out plate 31a "moves from a position where the flow of the fertilizer to the funnel 36 is not obstructed to a position where the flow of the fertilizer to the funnel 36 is prevented. The lid 31a 'can be opened to remove the fertilizer in the hopper 30 from the opened fertilizer discharge opening without flowing the fertilizer. By turning the whole strip feed amount adjusting handle 40 provided on the side, the axial groove lengths of the feed grooves 31e can be simultaneously changed and adjusted, so that the fertilizer is fed per rotation of the feed roll 31b. With the handle 40, all the feeding sections 31 can be simultaneously and simultaneously changed and adjusted by the handle 40, and the feeding sections 31.
