The handle 345 is fixed to the upper end of the operation lever 344 projecting upward through the support plate 346 fixed to the base plate 8.

Referring to the operation and effect of the present invention as described above are as follows.

When the operator sits in the driver's seat 9 to start the engine 2 and moves the operation handle 271 downward, the operation lever 270 rotates the operating rod 261 of the hydraulic valve 260 downward, Accordingly, when the hydraulic valve 260 is opened and the hydraulic oil is supplied to the hydraulic cylinder 220, the plunger 221 connected to the operation period 213 of the rotating beam 210 is extended, and the rotating beam 210 rotates. By doing so, the straightener 100 coupled to the rear end of the rotating beam 210 is lowered as shown in FIGS. 1 to 3.

As such, when the rotary spreader moves forward in the state where the water gutter opening 132 coupled to the direct wave frame 110 is landed on the ground of the plantation plant, the straight line 100 is lowered and is provided at the middle portion of the direct wave frame 110. The furrow is opened by the formed groove opening 132, and the bone is formed by the plurality of bone formation holes 134 coupled to both sides of the straightener frame 110.

Then, the output shaft 148 of the power transmission means 140 connected to the gearbox 20 is rotated to rotate the main shaft 141 by the bevel gears 143, 144, sprockets 145, 146 As the driven shaft 142 is rotated by the chain 147 and the chain 147, the discharge pipe 121 of each seeding box 120 of the straightener 100 is opened to discharge the seeds contained in the seeding box 120. Seeds fall on the bone formed by the plurality of bone formation holes 134.

If the bottom surface of the plantation slopes to one side while the rotary spreader moves forward, the straightener 100 is rotatably connected to the pivot support bar 214 of the pivot beam 210 by the shaft 212, and both tensions. Since it is elastically supported by the spring 135, the straightener 100 proceeds while the inclination is adjusted according to the bottom surface, whereby the furrow and the valley are formed at a uniform height even where the bottom surface of the plantation is inclined.

On the other hand, in a place where the bottom surface of the plantation is curved differently in height, the float 253 of the straightening device lifting height adjusting device 250 is rotatably coupled to the lower end of the float support bar 252 by a hinge pin 253a. And the adjusting rod 254 of the float 253 and the operating rod 261 of the hydraulic valve 260 are coupled by the porous connecting plate 255, so that the hydraulic valve 260 is moved up and down by the float 253. The operating rod 261 of the) is operated up and down to adjust the flow rate of the hydraulic valve 260, and accordingly the amount of expansion and contraction of the plunger 221 of the hydraulic cylinder 220 is adjusted, so that the height of the straightener 100 The lifting and lowering is automatically adjusted according to the bending, and the automatic adjustment action of the vertical movement of the float 253 and the vertical movement of the straightener 100 is automatically performed by the automatic hydraulic adjustment action of the hydraulic valve 260. Continue while moving.

The float 253 can be adjusted manually by raising or lowering the float support bar 252 with respect to the support tube 251 and fixed with a fixing pin 258, and to adjust the height of the float 253. If the height of the operating rod 261 of the hydraulic valve 260 is changed by the adjusting rod 254 of the float 253, the expansion and contraction length of the plunger 221 of the hydraulic cylinder 220 is changed, so that the straightener 100 is raised and lowered. The range of movement that can be adjusted is adjusted. @ At the beginning of operation, if necessary, the initial height is adjusted and operated according to the conditions of the plantation ground and the type of seeds to be sown. You only have to do it once in the beginning and you don't have to do it again while you're working.

Then, while the rotary spreader is moved, the power of the engine 2 is transmitted to the drive shaft 331 of the rotary spreader 300 rotatably installed at the rear portion of the body frame 1 to drive the drive shaft 331 and the driven shaft 332. When the driving pulley 333 and the driven pulley 334 are connected by the belt 335 and rotate together, the rotating lever 336 fixed to the driven pulley 334 is rotated and fixed to the body frame 1. One end rotatably coupled to the central shaft 321 and the other end is raised to slide the upper guide member 325, the rotating pipe rotator 322 rotates the rotational force of the rotation lever 336 and the ball rolling member 337 As it is delivered to the joint 339 and the spray pipe rotary lever 322 is rotated, the spray pipe 311 which is tied to the spray pipe rotary lever 322 and fixed is rotated together to be contained in the barrel 313 of the sprayer main body 310. The spraying of pesticides and the like is rotated uniformly. Here, the rotation lever 336, the transmission member 337 and the rotation lever 322 can be adjusted to the length of the production, if necessary, the length of the guide rail 320 can be adjusted as necessary, According to the length of these members can be produced by adjusting the rotation lever 322 and the spray pipe 311 to rotate in the range of a predetermined angle required. Of course, other parts can also be manufactured by changing the dimensions as needed during design production. And as shown in the transmission member 337, by adopting a turn buckle (turn buckle) structure can be adjusted to the length as necessary to smoothly rotate the interlocking parts even after assembling the device.

Then, by rotating the operation lever 344 provided next to the driver's seat 9, the intermittent shaft 341 rotatably coupled to the vehicle body frame 1 is rotated, and fixed to an end of the intermittent shaft 341. As the connecting rod 342 rotates, the compression lever 347 rotatably coupled to the body frame 1 by the shaft 347 'rotates and rotates between the supporting portions 348 of the intermediate portion of the compression lever 347. When the compression roller 343 coupled to be detached from the belt 335 connected between the driving pulley 333 and the driven pulley 334, the transmission of power between the driving pulley 333 and the driven pulley 334 is blocked and sprayed. The rotation of the pipe 311 is stopped, and as the operation lever 344 moves in the reverse direction, the operation is reversed, and when the pressing roller 343 is pressed against the belt 335, the power is connected again to spread the spray pipe ( 311) is rotated.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention described in the claims below. It will be appreciated.

The rotary spreader described above is to uniformly spread the spraying material such as pesticides while the sprayer automatically rotates when the automatic traveling straighter moves, so that the number of workers and time required for the spreading operation can be greatly reduced, and uniformity is achieved. There is an advantage that the spraying effect is increased by the spraying.
