Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat seedling supplying device for a rice transplanter for riding, which is capable of supplying mat seedlings from a passenger traveling vehicle to a seedling table of a planting section.

[0002]

2. Description of the Related Art Conventionally, a rice transplanter having a planting portion having a seedling table or the like which inclines forward and backward low is connected to the rear of a passenger traveling vehicle through a link mechanism so as to be lifted and lowered. As seen in Kaihei 7-135813, a seedling replenisher capable of receiving a mat seedling sent from a supply unit of the machine and supplying it to a seedling table is provided to a stay extending from the upper part of the seedling table. It is known that it is freely pivotable.

[0003]

However, with such a structure, the mat seedlings are sent to the seedling supply body when the whole seedling supply body moves up and down together with the seedling mounting base and the seedling mounting base is descending. Since the planting part pitches during the planting work, it is not possible to properly supply mat seedlings from the supply part to the seedling replenishing body, and moreover, the seedling replenishing body must be rotated by a hydraulic cylinder or the like. Since it is necessary to splice seedlings, the workability of seedling splicing is poor, and since the entire weight of the seedling replenisher and the like is applied to the seedling mounting table, it is necessary to reinforce the seedling mounting table or make the structure complicated. Is presenting.

[0004]

SUMMARY OF THE INVENTION The present invention solves such a problem and makes it possible to effectively supply mat seedlings to a seedling platform via a seedling supply body with a simple structure. In a passenger rice transplanter configured by connecting a planting section having a seedling table tilting frontward and rearward low to the rear of a passenger traveling vehicle via a link mechanism so that the planting section is located above the rear portion of the passenger traveling vehicle. A mat seedling supply section is provided, and a rear end section of the seedling supply section is pivotally attached to the rear section of the supply section, and a front end section of the seedling supply section on which the mat seedlings sent from the supply section can be placed. It is pivotally attached to the upper end side of the seedling mounting table, and when the seedling mounting table rises, the seedling supply body becomes substantially horizontal, and when the seedling mounting table descends, the seedling supply body becomes largely inclined. It is configured in.

Above the above, a seedling mounting table 1 having a plurality of seedling mounting surfaces and capable of reciprocating in a lateral direction is obliquely installed in a front high position and a low position, and has a structure similar to a conventional structure.

[0006] The supply section 3 provided above the rear cover 7 which is the rear section of the body of the passenger traveling vehicle A has mat seedlings C as many as the seedling mounting surfaces of the seedling mounting table 1 placed therein and rearward. The supply belt 3a that can be sent to the motor 16 is provided horizontally so as to be driven by the motor 16, and the mat seedlings C as many as the seedling placing surfaces of the seedling placing table 1 can be placed above the supply belt 3a. The auxiliary seedling stand 17 that can be constructed is constructed by being erected. However, the inside of the supply section 3 is limited to the supply belt 3a, and the preliminary seedling stand 17 is moved up and down.
The mat seedling C placed on the upper side can be configured to be supplied onto the supply belt 3a.

Further, at the rear part of the supply belt 3a,
The front end of a belt-shaped seedling replenishing body 4 on which each mat seedling C sent out from the supply belt 3a can be placed is pivotally attached, and the rear end of the seedling replenishing body 4 is placed at the upper end of the seedling placing table 1. It is pivotally attached to the side, but both side portions of the seedling supply body 4 are support frame plates 4
Each of them is supported by a, and the roll shaft 18 at the front end portion of the seedling replenishing body 4 is made to approach the terminal end portion of the supply belt 3a and is mounted on a transmission case 19 so that it can be transmitted from the supply belt 3a. 4 roll shaft 20 at the rear end
Is vertically mounted on the stays 21 on both sides extending from below the upper end of the seedling placing table 1, and when the seedling placing table 1 is raised, the seedling replenishing body 4 becomes substantially horizontal and When descending, the seedling replenisher is configured to be largely inclined.

The seedling replenishing body 4 may be made of a flat plate having a smooth upper surface.

Therefore, during the planting work, if the machine body turns on the headland side, the planting section B is raised, but as shown in FIG. When the motor 16 is started when the replenishment body 4 becomes substantially horizontal, a plurality of mat seedlings C placed on the supply belt 3a in advance are sent out to the seedling replenishment body 4, and the motor is started. By stopping 16, each mat seedling C is left above the seedling supply body 4.

When the planting work is carried out again while the machine body turns to lower the planting section B, as shown in FIG. 1 and FIG. It will be greatly inclined, and each mat seedling C on the seedling supply body 4
The belt is rotated by the start of the motor 16 or is vibrated by the pitching of the planting portion B to be smoothly sent out onto the seedling placing table 1, and the seedling splicing is effectively replenished.

When the seedling table 1 reciprocates in the lateral direction, the stay 21 simply slides with respect to the roll shaft 21.

FIG. 4 shows another first example, in which a part of the riding rice transplanter is configured in substantially the same manner as indicated by the same reference numeral,
A mat seedling provided on the rear cover 7 of the passenger traveling vehicle A is connected to the rear portion of the passenger traveling vehicle A by connecting the front end portion of the support transmission portion 22 extending forward from the planting portion B to the rear portion of the passenger traveling vehicle A in a freely movable manner. The rotation fulcrum 26 of the seedling splicing stand 25 provided between the feeding stand 24 of C and the seedling stand 1 of the planting section B is
It is constructed by being provided on the upper part of a support stand 27 which is erected above the support transmission section 22 on the front side of the machine body, and the seedling joint stand 25 is automatically synchronized with the seedling stand 1 when rolling or moving up and down. The seedling can be reliably and satisfactorily performed.

FIGS. 5 to 10 show another second example, in which both guide rods 28, 28 are provided above the seedling table 1 which reciprocates laterally in the planting portion connected to the passenger traveling vehicle. A seedling placing device 30 for seedling splicing, which slides and is biased to one side by both tension springs 29, 29, is provided, and the seedling placing table 1 moves in the direction of arrow A below both ends of the seedling placing device 30. Engagement protrusions 3 provided above both ends of the seedling mounting table 1 when performing
Engaging projections 32, 32 respectively engaged with 1, 31 are provided respectively, and when the seedling placing table 1 moves in the direction of the reverse arrow a, the seedling placing device 30 is restored by being pulled by both tension springs 29, 29. Although it is configured to move, as shown in FIG.
The engaging projection 31 engages with 32 in the direction of arrow a.
As shown in FIG. 7, it is also possible to configure so that the seedling placing device 30 does not move while being pushed by the engaging projection 31 in the arrow B direction and rotating the engaging projection 32 as shown by the arrow C.
As shown in FIG. 9, a lid 33 for supporting the mat seedling C is rotatably provided under the seedling placing device 30, and as shown in FIG. It is configured so that the seedlings can be sent out and the seedlings can be satisfactorily spliced.

FIG. 11 shows another third example, in which the seedling box 34 is loaded with the mat seedlings C, and the seedling box 34 is placed on a support base 36 that can be placed on the transport belt 35 and transported. As shown in the drawing, the end of the conveyor belt 35 can be disassembled and taken out.

FIG. 12 shows another fourth example. When the planting section rises, the upper part of the seedling mounting table 1 is located below the rearmost supply port 38 of the seedling supply table 37 provided at the rear of the passenger vehicle. As the seedlings are brought closer to each other, the matting seedlings C are tilted so that the mat seedlings C can be easily replenished, the spare seedling mounts 39 are placed side by side, and the spare seedling mounts 39 are moved to supply seedlings from the supply port 38. The table 1 is configured so that the mat seedlings C can be supplied.

[0016]

As described above, according to the present invention, for example, when the riding rice transplanter raises the planting part B while turning in the field, the seedling replenishing body 4 becomes substantially horizontal and the planting part B is The mat seedling C can be smoothly and satisfactorily delivered from the supply section 3 onto the seedling supply body 4 which is stable because it is not pitched because it is rising. When the attachment B is lowered and the planting work is restarted,
Since the seedling replenishing body 4 is automatically inclined greatly, the matting seedlings C above it can be smoothly and satisfactorily replenished on the seedling mounting table 1, and the workability of seedling splicing can be further improved. Moreover, since the front part of the seedling replenishing body 4 is pivotally connected to the rear part of the supplying part 3, the weight of the seedling replenishing body 4 does not burden the seedling mounting table 1, The front and rear portions of the replenishment body 4 have a characteristic that they can be suitably implemented because they can be made into a simple structure in which they are pivotally attached and connected.
