In other words, the seedling sowed with soil and seeds in the sowing machine is rapidly transported and supplied to the stacking frame. In the stacking frame, the transferred sowing seedlings are arranged in the stacking frame and discharged in an aligned state. In this process, It is necessary to delay the feeding speed of the sowing seedlings supplied to the stacking frame so that the overall working process is slowed down.

In the prior art document 1, although the area of the loading frame is wide due to the seedling placed in the loading frame, there is a limit in accommodating the food frame being arranged in the loading frame compared to the large area loading frame. It is disadvantageous in that the work efficiency and the production efficiency are lowered because it is not possible to provide a seedling.

The techniques of the seedling box transporting device and the stacker as described above are described in detail in the following prior art documents, so that detailed description thereof will be omitted.

In particular, the lifting plate 170 is provided on the loading portion 150 in an inclined manner. That is, one end of the base frame 110 is slanted lower than the other side of the lift frame 170, and the slope angle of the lift frame 170 is inclined by 5 to 10 degrees.

This is because the seedlings box 10 is provided at the tip of the base frame 110 so that the seedlings box 10 can be mounted on the loading unit 150 by the elastic force of the stopper plate 160, (The opposite direction in which the seedlings box 10 is fed). When the lifting box 170 is lifted by the hoist box 10 horizontally installed in the loading unit 150, the front end of the shearing box 10 is spaced apart from the front guide bracket 154, The rear end of the seedling box 10 is hooked on the bending protrusion 155a of the rear guide bracket 155 so that a load is applied to the rear end of the seedling box 10, do. Consequently, the seedlings box 10 can not be lifted horizontally, and the tip is lifted faster and lifted to a tilted state, so that the sown soil and the seed are pushed to one side.

Therefore, when the angle of inclination of the lifting plate 170 is less than 5 degrees, when the lifting seedling box 10 contacts the bending protrusion 155a of the rear guide bracket 155, When the seedling box 10 contacts the bending protrusion 155a of the rear guide bracket 155 and the front end of the seedling box 10 is lower than the rear end of the rear guide bracket 155, It is most preferable to adjust the inclination angle of the lift steel plate 170 to between 5 and 10 degrees.

A recessed groove portion 171 for avoiding interference between the lift plate 170 provided on the mounting portion 150 and the conveyance roller 112 provided on the rotary shaft 111 is formed on the outer peripheral portion of the lift plate 170 And the conveying roller 112 of the rotary shaft 111 is protruded to the upper portion of the lifting plate 170 by the recessed groove 171 so that the seedlings box 10 can be transported. Therefore, the lifting plate 170 is provided between the rotary shaft 111 and the seedlings box 10 so as not to interfere with peripheral parts, especially the supporting plate 152, when lifting.

In addition, the actuator provided as described above can adjust the moving distance of the piston rod 173 drawn out from the cylinder body 172, and is fixed to the lower portion of the lift plate 170, A switch plate 175 provided on the lifting bar 174 and moved as the lifting bar 174 and a switch plate 175 provided on the base frame 110 to be lifted up and down And a second limit switch 190 that is switched by the second limit switch 190 to control the lift operation of the lift plate 170.

That is, when the switch plate 175 contacts the second limit switch 190, the lifting of the lifting plate 170 is stopped and descended.

A hollow coupling bushing 175a is integrally formed on one side of the switch plate 175. When the elevating bar 174 is coupled to the coupling bushing 175a, So that the switch plate 175 is fixed to the lifting bar 174. [ The fixing bolt 176 fastened in this way can fix the switch plate 175 to the lifting bar 174 by a pressing force that pushes the outer surface of the lifting bar 174 through the end of the fixing bushing 175a .

Thus, the switch plate 175 provided on the lifting bar 174 can easily adjust the position of the switch plate 175 when the fixing bolt 176 coupled to the coupling bushing 175a is loosened and tightened, The width of the lifting plate 170 can be finely adjusted depending on the position of the lifting plate 175.

As shown in FIGS. 5 and 6, a sensing unit for sensing whether the actuator is operating or not is detected by sensing the seedlings box 10 supplied into the loading unit 150, as shown in FIGS. 5 and 6, at the inner tip of the loading unit 150 .

The sensing means includes a stopper plate 160 that is rotatably mounted on the loading unit 150 and rotates in contact with the seedlings box 10 supplied into the loading unit 150, And a first limit switch 180 that is switched by the first limit switch 180 to actuate the actuator.

The second elastic member 163 is a compression coil spring having one end connected to the rotation bracket 162 and the other end connected to and fixed to a fixing pin 164 provided on the base frame 110. The second elastic member 163 is stretched by the rotation bracket 162 which rotates together with the stopper plate 160 when the seedling box 10 is brought into contact with the stopper plate 160, It is possible to buffer the impact of the seedlings box 10 to be contacted and to restore the rotation bracket 162 and the stopper plate 160 to their original state by the compressive force.

When the rotary bracket 162 presses the first limit switch 180 in response to the above operation, the actuator provided under the loading unit 150 is operated in conjunction with the rotation of the piston rod 173 Is pulled out and the lift steel plate 170 is lifted.

The loading process of the seedling box loading apparatus according to the present invention will now be described.

In the seeding machine, the seedlings box 10 in which soil and seed are sown is discharged from the seeding machine and is fed to the stacker 150 for feeding.

At this time, the feeding speed of the seedlings box 10 supplied to the stacking unit 150 is faster than the feeding speed of the seedlings box 10 to be delivered from the seeding machine, So that they can be quickly loaded and supplied to the next process.

In this process, a shock is applied to the seedling box 10, which is transported at a constant speed to the stopper plate 160 and is in contact with the seedling box 10, so that the seeds and seeds that have been sown can be pulled toward the tip of the seedling box 10, The second elastic member 163 provided between the base frame 110 and the base frame 110 is tensioned to buffer the impact to prevent the soil and the seed from being frozen in the seedlings box 10. [

An actuator provided under the loading unit 150 is operated by the switched first limit switch 180 so that the piston rod 173 is drawn out from the cylinder body 172 to move the lift plate 170 to the loading unit 150 As shown in FIG.

The lifting plate 170 thus lifted is provided with the seedlings box 10 supplied to the loading unit 150 on the upper surface thereof and rotates the supporting plate 152 rotatably provided on the vertical frame 151 And the rotated support plate 152 is rotated backward by the first elastic member 153 from the point at which the seedlings box 10 is lifted further from the support plate 152 to be supported by the support plate 152, The support plate 152 is fixed to the vertical frame 151 in a vertical direction.

Particularly, as described above, the seedling box 10 lifted by the lifting plate 170 is provided in a state of being separated from the front guide bracket 154 due to buffering action due to contact with the stopper plate 160, The rear end of the seedling box 10 is brought into contact with the bending protrusion 155a of the rear guide bracket 155 by the lifting plate 170 so that the seedling box 10 is advanced and moved to the front guide bracket 154 The load caused by the guide brackets 154 and 155 is uniformly applied to the front and rear ends of the seedlings box 10, so that the seedlings box 10 is lifted in a horizontal state.

The lifting bar 174 provided below the lifting plate 170 and the switch plate 175 are simultaneously lifted by the lifting steel plate 170 to switch the second limit switch 190.

The lifting of the piston rod 173 is stopped by the switched second limit switch 190 and is then lowered again so that the lifting plate 170 and the seedlings box 10 are also lowered by the lowering of the piston rod 173. [ The lifting plate 170 is lowered onto the rotary shaft 111 after passing through the support plate 152. The edge portion box 10 is hooked on the support plate 152 with its rim portion 11 held thereon.

Therefore, the seedlings box 10 and the lift plate 170 hooked to the support plate 152 are spaced apart from each other, and another seedling box 10 is supplied between the lift plate 170 and the seedlings box 10, Is lifted by the lifting plate 170, which is operated as described above, and is hooked on the supporting plate 152 of the vertical frame 151 again.
