The present invention is installed separately on the cultivator wheel, and when moving to the arable land, the triangular protrusion track rotating around the inside of the annular pipe support piece is operated by touching only the folded tire part to the road surface. It relates to a cultivator attaching iron wheel that enables to work without the wheels falling out.

Conventional tiller wheels are larger than the diameter of tires, so if you want to move to farmland, you have to put iron wheels and rotary parts on the trailer and get rid of the rubber tires when you arrive at the workplace. There was a risk that the adjustment would be risky, would require a lot of manpower, and would take a long time, resulting in deterioration of work efficiency when arguing.

The present invention focuses on the drawbacks described above, and folds the iron wheel for cultivator attachment to the workplace, or when returning home, folds the track of the iron wheel and easily deploys it in agricultural fields such as paddy fields so that it can be used without any inconvenience quickly. It will be described in detail by the accompanying drawings that are designed to work efficiently by moving as follows.

A plurality of support pieces 4 and 4 'formed with recessed grooves 2 and 2' around the annular pipe 1 and having curved portions 3 and 3 'are provided at appropriate intervals therebetween. (5) with long sleeve (7) and long hole (7) (7 ') drilled and integral with the triangular protrusion (8) at the bottom " A spring 12 is attached to the protruding pin 11 to which the " shaped track 9 " is adhered, and the washers 10, 10 'are fixed on both sides thereof. (14) is connected.

Reference numeral 15 denotes a fastening hole, 16 denotes a reinforcing piece, and 17 denotes a tiller wheel.

The present invention, as described above, is used in a state in which the binding plate 14 is fastened to a conventional tiller wheel 17 in a state of working as in the rice paddies and the like as shown in FIG. The tubular body 6 with the inlet hole 5 is interposed between the support pieces 4 and 4 'provided at a suitable interval in the inner space and integral with the triangular protrusion 8 at the bottom. "The protruding pins 11 are inserted into the springs 12 of the support grooves 4 and 4 'on one side of the recessed groove 2 supported by the mold track 9. "A strong safety support, acting as a safety valve to prevent the type track (9) from coming off, installed multiple" "The triangular projection 8 integrated with the shape track 9 is as long as the width of the bottom contact portion of the cultivator wheel so that it does not idle when advancing in water paddles, etc. (10 ') is integrally fixed to the protruding pin 11 so that the spring 12 is always kept closed regardless of the contraction or repulsion of the spring 12, so that soil does not splash during the work in the paddy field. ) Works all the time so you can continue working efficiently.

And when returning to work or when entering the paved road simply push the protruding pin 11 in the direction of the triangular bulge (8) to shrink the spring 12 inside the recessed groove of the support piece (4) (4 ') 2 ') to the end and then rotated 180 ° to fold and the protruding pin 11 grabs the curved portion 3' of the support piece 4 and 4 'and at the same time the annular pipe in the support piece 4 and 4'. (1) serves as an axial rod, and the inner tube (6) portion of the inner tube (5) is rotated so that when the protruding pin 11 sweeps the curved portion (3) of the support piece (4) (4 ') the internal spring ( When the back 12 is pushed back into the recessed groove 2 of the support piece 4 and 4 ', the spring 12 is retensioned and becomes as shown in FIG. 4 (b). Even if the tiller wheel rotates at a high speed, the folded state is maintained.

The present invention is connected to the binding plate 14 and the annular pipe (1) by the curved connecting rod (13) to the space portion " "It is easy to fold the shape track 9 and it is quick to move in the workplace and any place, but it can be easily deployed and used in water paddy fields, etc. Buried to promote the growth of crops, and if the wheels in the puddle, etc., while moving the cargo, the tracks can be easily released by running their own tracks. It is a useful design that can work efficiently while saving money.

Claims (1)
