Description

[Detailed Description of the Invention] The present invention relates to a body structure of a walk-behind rice transplanter that can be changed to a direct sowing type.

In other words, the transmission case that extends to the rear of the fuselage is equipped with an engine at the front and wheels on both sides, and the planting case that drives the planting claws and seedling stand is connected to the rear of the transmission case, and the transmission case that drives the planting claws and seedling stand is connected to the rear of the transmission case. This walk-behind rice transplanter consists of an extended handle rod, and can be used to perform planting using conventional planting claws or direct seeding, making it a versatile rice transplanter. To provide a machine body structure that is flexible and convenient to use, and has a simple structure so that it can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a partially cutaway side view of the rice transplanter. On both sides of the rear of the engine E mounted above the front of a long float 8, a swing type transmission case 9 with a wheel 1 mounted on the tip is installed. The rear end flange 10 of the transmission case 2 extending from the rear side of the engine E to the rear side of the aircraft body has a flange 1 fixed to the front ends of both pipe-shaped frames 7, 7 extending in the longitudinal direction.
1 and fastened with each bolt nut 12,
The tip of the drive wheel 13 extending inside the transmission case 9 projects into the case 14 of the flange 11, and the PTO shaft 1 projects rearward within the case 14.
5 through a gear 16, handle rods 5, 5 are respectively extended from the rear portions of both frames 7, 7 to the rear upper part, and an operation box 17 is installed between both handle rods 5, 5. Support pieces 18a and 18b are provided vertically below both frames 7 and 7 in the front and rear, and a planting depth adjustment lever 19 is interposed between the rear part of the float 8 and the support piece 18b.

Further, a horizontal mounting base 7a is fixed on the upper surface of both frames 7, 7, and a plurality of mounting holes 21 into which bolts and nuts 20 can be inserted are bored on both sides of the mounting base 7a, and the mounting base The lower support stand a of the planting case A is connected to the upper surface of the planting case A and is removably fixed with each bolt nut 20, and the input shaft 6 protruding forward from the lower part of the planting case A is connected to the PTO shaft 1.
5 through a joint 22 so that it can be detachably connected to the transmission case, and a rotating shaft 23 for driving the planting claws 3 is protruded from both sides of the lower part of the planting case A, and the lower support base a
A horizontally elongated seedling take-out plate 24 is provided in series at the rear of the seedling table 4, and connecting plates 25 are provided extending from both sides of the lower part of the seedling platform 4, which extends upward from the seedling take-out plate 24 and is movable laterally. The upper portions of both connecting plates 25 are fixed to both ends of a shaft 26 that protrudes from the upper connecting side of the planting case A and reciprocates in the lateral direction.

Reference numeral B designates a seeding unit for direct sowing, in which a hopper 28 with a feed roll 27 mounted on its lower part is installed above, and an input shaft 6a for driving the feed roll 27 is connected from the bottom forward through the joint 22. hand
The lower support stand 29 is installed so as to be connectable to the PTO shaft 15 in a transmission manner, and the lower support stand 29 is installed so as to be removably connected to the mounting stand 7a through each bolt nut 20, and extends downward from the rear of the feed roll 27. A shutter 30 having both discharge ports is installed vertically.

Further, 31 is a float whose upper part is connected to the support piece 1.
8a, 18b so that it can be detachably connected to the float 31, and cutouts are formed on both sides of the rear of the float 31 as in the conventional type, and a groove forming body 32 is provided on the lower surface of the float 31 in front of both cutouts. Cultivating soil body 3 at the rear
3 are installed and configured.

FIG. 8 shows another embodiment, in which a stud bolt 34 protruding from the lower part of the planting case A or the seeding unit is installed in the rear end flange 10a of the transmission case 2 so that it can be detachably inserted and connected. Transmission case 2
The input shaft 6a from the planting case A side is installed on the distal end side of the inner drive shaft 13a so as to be transmission-connectable via a joint 35.

Therefore, as shown in FIGS. 1 and 2, the support stand a of the planting case A is joined to the mounting stand 7a and fixed with each bolt nut 20, and the input shaft 6
By connecting the rice transplanter to the PTO shaft 15 and attaching the float 8 downward, it is possible to construct a rice transplanter that can perform the same planting as conventional rice transplanters.

Also, remove the planting case A, the seedling stand 4, and the float 8, and as shown in FIGS. , the input shaft 6a
By connecting the float 31 to the PTO shaft 15 and connecting the upper part of the float 31 to the support pieces 18a and 18b, the rice transplanter can be changed to a submerged direct sowing machine.

In this way, the present invention has an engine E in the front and wheels 1 on both sides, and a transmission case 2 that extends toward the rear of the machine. The planting case has an input shaft 6 that is detachably and detachably connected to the transmission case 2 in a walk-behind rice transplanter configured by connecting the case A and a handle rod 5 extending to the rear of the machine body. A is removably connected to the rear of the transmission case 2 or to the side of the frame 7 extending from the transmission case 2, and when the planting case A is removed, a seeding unit B for direct sowing can be similarly attached. Since it is installed and configured in this way, when the planting case A is attached, the rice transplanter can be used for planting using the conventional planting claws 3, and when the sowing unit B is attached in the same way, the rice transplanter can be used for planting. This means that it can be made into a water direct sowing machine, and the machine structure can be made to be versatile and convenient to use, and it has the advantage that it can be easily implemented with a simple structure.
