A driver's seat 21 is attached to the upper portion of the vehicle body cover 20, and a steering handle 22 is provided in front of the driver's seat 21.

  At the rear of the traveling vehicle body 10, a rice planting machine (seedling planting machine) 30 including a seedling mounting table 31 for planting eight rows and a plurality of planting claws 32 is connected. This rice transplanter 30 is connected to the traveling vehicle body 10 using a three-point lifting link mechanism including a top link 33 and a lower link 34. And, it is configured to be movable up and down by an expansion and contraction operation of a hydraulic cylinder interposed between the rear portion of the traveling vehicle body 10 and the lower link 34. Further, the plate-shaped forward tilting seedling table 31 installed at the front height and the rear height is reciprocated with respect to the center and left and right planting transmission cases 37 via the lower guide rail 35 and the upper guide rail 36. It is supported freely. Below the planting transmission case 37, center and left and right planting flat floats 38 and 39 are supported via planting depth adjusting members. The planting work machine 30 is lowered and the floats 38 and 39 are landed to set the planting depth of the seedlings to be taken out from the seedling mat on the seedling mount 31 (FIG. 1, FIG. 1). In FIG. 2, the seedling mat is omitted). In the planting transmission case 37, the rotating shaft rotates with the driving force extracted from the PTO shaft of the traveling vehicle body 10.

  In FIG. 3, the front view of the rice transplanting machine 30 is shown. The rice planting machine 30 is integrally provided with eight seedling platforms 31A to 31H (one seedling platform corresponds to one line at the time of planting). Two conveyor belts B for conveying the seedlings downward are provided in parallel on the bottom bottom surfaces of the seedling platforms 31A to 31H. The conveyor belt B is made of a rubber endless belt, and has numerous small protrusions on the surface and protrusions formed at regular intervals on the back surface. The transport belt B rotates by engaging with a pair of plastic gears on the back side of each of the seedling platforms 31A to 31H. The drive shaft branched from the PTO shaft is engaged with the rotation shaft of the one gear through the gear.

  Four hopper units 73A to 73D, which will be described in detail later, are provided in front of the center of the seedling platforms 31A to 31H. The hopper units 73A to 73D are configured to supply chemicals and fertilizers to the seedling platforms 31A to 31H for two strips, respectively. Specifically, the hopper unit 73A is on the seedling platforms 31A and 31B, the hopper unit 73B is on the seedling platforms 31C and 31D, the hopper unit 73C is on the seedling platforms 31E and 31F, and the hopper unit 73D is on the seedling platforms 31G and 31H. It is configured to supply drugs and fertilizers.

  Each of the hopper units 73A to 73D has the same configuration, and includes a hopper tank 74, a medicine feeding roller portion 75, a discharge pipe 76, a spray port 77, and the like (see FIG. 5). The center of the bottom surface of the hopper tank 74 is V-shaped when viewed from the front. At the bottoms of both ends of the hopper tank 74, a medicine feeding roller part 75 is provided. The outer shell of the medicine feeding roller unit 75 is formed integrally with the hopper tank 74. And a transverse groove roller is rotatably provided inside.

A rotation drive shaft (not shown) branched from the PTO shaft is attached to the horizontal groove roller. By integrally molding the hopper tank 74 and the medicine feeding roller portion 75, water leakage at the connecting portion, which has been a problem in the past (rain water enters from the connecting portion, moistens the granular medicine, (Problem of being stuck to the feeding roller portion 75) can be avoided.

  A delivery pipe 76 is attached to the lower end of each medicine supply roller portion 75 continuously. In this way, two lead-out pipes 76 are attached to one hopper tank 74, and each lead-out pipe 74 is responsible for supplying the medicine to one seedling stage 31 (therefore, one hopper tank 74 has 2 The drug is supplied to the seedling stage 31 of the stipulation). Specifically, a rod-shaped weeding board (not shown) above the seedling stage 31 and above the spraying port 77 is placed on the upper part of the rice seedlings that are conveyed downward on the seedling stage 31 when planting rice. The seedling is bent slightly upstream in the transporting direction of the seedling and is provided over the entire width direction of the seedling mounting table 31). As a result, an open space is formed between the bent seedling and the seedling adjacent to the downstream side (the seedling that has already passed through the weed board and released from the deflection and stands upright), and sprayed toward this open space. The medicine is sprayed from the mouth 77.

  A spout 77 is continuously provided at the lower end of the outlet pipe 76. The spray port 77 has a double structure. That is, a cylindrical wheel is provided on the outside, and a nozzle is provided on the inside. A plurality of protrusions are provided on the outer periphery of the wheel. This protrusion comes into contact with the seedling placed on the seedling placing table 31. Then, when the seedling stage 31 moves in the width direction so as to feed out the seedling at the time of rice planting, the protrusion is caught by the seedling, and the wheel outside the spraying port 77 rotates. Therefore, the wheel rotates at a constant speed while the seedling stage 31 is feeding the seedling. One end of a scraper made of a wire is fixed to the wheel. The other end of the scraper is inserted into the nozzle. And a scraper rotates in a nozzle because a wheel rotates. By comprising in this way, it can prevent that a water | moisture content adheres to a nozzle exit, and the chemical | medical agent discharged | emitted from the spraying port 77 is solidified by the water | moisture content to the spraying port 77 periphery.

  The seedling platforms 31A to 31H are grouped into four units by the hopper units 73A to 73D. That is, the seedling platforms 31A and 31B are first units, the seedling platforms 31C and 31D are second units, the seedling platforms 31E and 31F are third units, and the seedling platforms 31G and 31H are fourth units. In addition, the seedling mounting bases 31A to 31H are connected by bringing the connecting levers (lock levers) provided two at each edge to the locked state. In addition, a pipe-shaped stand S, which will be described later, is fixed on the left edge of the seedling table 31E and the right edge of the seedling table 31F. Furthermore, a pin (protrusion) R that fits to the tip of the stand S is provided on the left side rear surface of the seedling table 31A and the right side rear surface of the seedling table 31B. The pin R and the tip of the stand S are further provided with a patch lock, and are locked by the patch lock.

  Further, four planting transmission cases 37 are provided in front of the lower parts of the seedling mounts 31 </ b> A to 31 </ b> H, and planting claws 32 are provided at both ends of each planting transmission case 37. That is, two seedlings can be planted with one planting transmission case 37.

  The hopper units 73 </ b> A to 73 </ b> D are placed on a series of cradle (frame) 72 and are fixed with a patchon lock or the like. This pedestal 72 is supported by brackets that stand up from the four planting transmission cases 37. The cradle 72 includes a holding portion 72a. The holding portion 72a is for temporarily placing the hopper units 73A to 73D.

  Next, a method of narrowing the width of the seedling mounting table 31 by folding the first units (the seedling mounting tables 31A and 31B) of the seedling mounting tables 31A to 31H after the rice planting operation is completed will be described. As shown in FIG. 4, the hopper unit 73C in front of the third unit (the seedling stands 31E, 31F) is removed from the cradle 72 and is placed on the holding portion (below the hopper unit 73D) of the cradle 72. Place and fix with patchon lock.

  Then, in a state where the seedling stage 31A and the seedling stage 31B are connected, the connection between the seedling stage 31B and the seedling stage 31C is released. Specifically, the two connecting levers provided at the edge of the seedling table 31B are rotated in the direction of releasing, and the connection between the seedling table 31B and the seedling table 31C is released. Next, the first unit is moved by holding the handles at both ends of the first unit (the seedling mounts 31A and 31B).

  Then, the first unit is overlaid on the third unit (seedling stage 31E, 31F). Specifically, the two pins R provided in the first unit are fitted into the tips of a pair of stands S provided in the third unit (FIG. 5). Next, it is locked with a patch (not shown). And the front-end | tip of the hook-shaped fixing pin with which the left end part of a 3rd unit is equipped is latched in the hole formed in the back surface of a 1st unit. Next, the seedling extraction plate of the portion where the first unit is placed is folded. By doing in this way, the width | variety of the rice transplanting machine 30 becomes below the vehicle width of the traveling vehicle body 10. FIG. Then, in a state where the traveling vehicle body 10 and the rice transplanter 30 are connected, they are loaded onto a truck or the like and conveyed.

  In addition, a 1st unit can be expanded from a folding state by performing the above-mentioned procedure reversely. Therefore, detailed description is omitted.

  In this example, an 8-row seedling stage is used, but the present invention is not limited to this, and may be applied to a 7-row seedling stage, for example. In this case, three hopper units for two strips and one hopper unit for one strip are provided.

  In the above-described example, the outlet pipe 76 and the spray port 77 extending from the hopper tank 74 supply the medicine to the root of the seedling bent by the weed board, but the present invention is limited to this. It is not a thing. For example, fertilizer and herbicide are introduced into the hopper units 73 </ b> A to 73 </ b> D, and the outlet pipe 66 ′ is extended to the outside of the planting claws 32 as shown in FIG. 6. Then, in accordance with the planting of the seedlings, fertilizer and herbicide are introduced into the roots of the seedlings from the spout 77 ′.

  The seedling planting machine of this invention is not limited to rice seedlings, and can be applied to planting all kinds of seedlings.
