Means for Solving the Problems In order to achieve the object, the present invention provides a riding rice transplanter in which a weeding rotor device in which a plurality of rotors are rotatably arranged via a lifting link at the rear of the machine is detachably mounted. ,
A plurality of forcedly driven rotors provided on a rotationally driven drive shaft for weeding the weeding rotor device between mechanically planted streaks corresponding to the number of planting streaks in one step of the riding rice transplanter; In order to remove weeds between artificial planting strips existing on both outer sides of the rotor, the free-running rotor is rotatably and detachably disposed on a rotary shaft integrally provided with the drive shaft adjacent to both ends of the forcibly driven rotor. The gist of the present invention is that the idle rotation assist rotor is constituted.

Effect The weeding rotor device forcibly drives the rotor between the mechanically planted streaks corresponding to the number of planted streaks in one stroke of the rice transplanter by means of the forcedly driven rotor, and at the same time, the idler assist rotor artificially implants the seedlings at the end of the stump in the adjacent stroke. Weed while rolling between the appendages.

An embodiment of the weeding rotor device of the present invention will be described with reference to the drawings.

In the drawing, a weeding rotor device B is extended via a parallel link mechanism 1 disposed behind the machine A of the riding rice transplanter in a C-shape in plan view by expansion and contraction of a hydraulic cylinder (not shown). It is detachably mounted so as to be able to move up and down while maintaining a horizontal posture by the balance action. In the weeding rotor device B used here, a work implement side hitch 4 is detachably connected to a main machine side hitch 3 provided on a free end side of the parallel link mechanism 1, and a rolling machine is mounted on the work implement side hitch 4. A frame 6 is connected via a fulcrum shaft 5.
Further, the rotor portion R is connected via the frame 6.

As shown in FIG.
Power is transmitted from a PTO shaft (not shown) provided through the universal joint shaft 7 to a gear case 8 and a transmission case 9 via a universal joint shaft 7, and the drive shaft 10 is driven to rotate. A plurality of forcibly driven rotors C, C... Arranged at appropriate intervals so as to be located in the strips after planting, and a rotating shaft integrally provided with the driving shaft 10 at both ends of the driving shaft 10. The idle assist rotors D, D are detachably mounted on the 11, 11 and are freely attached to the rotor. In the figure, reference numeral 11a denotes a stopper pin, 12 denotes a weeding plate disposed in front of each of the rotors C, C for preventing seedling entrainment, and 13 denotes a cover for preventing mud scattering.

Next, the operation and working example of the weeding rotor device B of the present invention will be described. First, the planting section (not shown) is removed from the machine A of the riding rice transplanter, the weeding rotor device B is connected via the hitches 3 and 4, and the machine A is operated to start the outward work. At this time, the power from the PTO shaft (not shown) of the machine A is transmitted to the universal joint shaft 7, the gear case 8, and further to the transmission case 9, and the forcibly driven rotors C, C. As shown in FIG. 3, while mechanically driving and rotating five mechanical planting strips L, L... Corresponding to the number of planting strips (six in the illustrated example) in one stroke of the planting section. and at the same time weeding idle auxiliary rotor D, D is between M ₁ and seedling N ₁ adjacent the ridge U, and, artificial planting condition M ₂ between the planting end seedling N ₂ and N ₃ in the adjacent stroke to herbicides while ground rolling on the end seedlings N ₂ closer. Next, the machine A is turned on the headland to perform a return trip operation. In this case, whereas herbicidal the end seedling N ₃ side of the artificial planting conditions between M ₂ and planting end seedling N ₂ and N ₃ in adjacent stroke side idler auxiliary rotor D 'has herbicidal the forward work At the same time
The forcibly driven rotors C ', C' ... weed the five mechanically planted strips L ', L' ..., and the idler auxiliary rotor D 'on the other side was planted at the planting end seedling in the adjacent stroke. the N ₄ and artificial planting conditions between M ₃ and N ₅ respectively to herbicides. Then, the same operation may be sequentially performed to remove the weeds on the rice field T.

By the way, since the auxiliary rotor D employs a system in which the rotating shaft 11 is freely rotatable, the auxiliary rotor D can be disposed without burdening the output of the PTO. By performing the work twice on the outward path and the return path between the artificially planted strips between the planted end seedlings in the process, the middle tillage and weeding action can be reliably performed. Further, since the weeding rotor device B is rotatably connected to the machine A via the rolling springs 2, 2, it is always held in a horizontal posture regardless of the inclination of the machine A, and the middle tillage and weeding action is achieved. Is performed at a uniform depth between the strips, so that there is no occurrence of unworked strips for middle tillage and weeding. Further, since the weeding rotor device B in the present invention is pulled by the riding machine A of the riding rice transplanter, the functional characteristics of the machine A can be used as they are in the middle cultivation and weeding work in the paddy field, and the efficient middle cultivation and weeding work can be performed. It can be carried out. That is, the tractor-towed weeding rotor device cannot perform paddy field work in a state where crops are being grown, but the present invention uses a riding rice transplanter, which is a dedicated paddy field vehicle. Without stepping on the wheels or ruining the field scene, and by operating the inter-stock transmission that is standard on the riding rice transplanter,
The rotation speed of the rotor portion R can be adjusted to an optimum speed in accordance with the weed condition in the field.

The present invention can be applied to a walking type rice transplanter, a dedicated machine for weeding rotors, and the like, and can be used not only for paddy fields but also for middle tillage and weeding work in upland crops.

Effect of the Invention As described above, the present invention relates to a riding rice transplanter in which a weeding rotor device in which a plurality of rotors are rotatably arranged via a lifting link at the rear of the machine is detachably mounted, and the weeding rotor device is used. A plurality of forcedly driven rotors provided on a rotationally driven drive shaft for weeding between mechanical planting strips corresponding to the number of planting strips in one step of a rice transplanter, and are present on both outer sides between the mechanical planting strips. A free-rotating auxiliary rotor that is freely and detachably disposed on a rotating shaft that is provided integrally with the drive shaft adjacent to both ends of the forced-drive rotor so as to weed between artificial planting strips. With this configuration, when the forcibly driven rotor is positioned between the mechanically planted strips corresponding to the number of planted strips, the idler rotor is positioned between the artificially planted strips between the planted ends in the adjacent stroke. Each forcibly driven rotor and idle rotation Since weeding is performed with the rotor, efficient weeding work can be performed.

Further, merely by positioning the rotor of the forced drive between the mechanically planted strips corresponding to the number of planted strips, the idle rotation assisting rotor simultaneously comes into the artificially planted strip adjacent to the end of the number of planted strips. By using a free-rotating auxiliary rotor that can slide and contact the ground, for example, when the spacing between artificially planted strips is small, the outer end of the free-rotating auxiliary rotor may contact adjacent seedlings. Even if there is, it is not forcibly driven, so that weeding work that causes less damage to the seedlings can be performed.

Further, in the return trip of the next step, the weeds between the artificial planting weeds on the outward trip are re-weed with the idle rotation auxiliary rotor, so that even the idle rotation auxiliary rotor that rotates on the ground can reliably perform the middle tillage and weeding work. it can.
