The present invention relates to a seedling planting device, and more specifically, to an improved device that allows seedlings grown to the size of a seedling to be easily planted and transplanted in a raised bed, while supplying fertilizers necessary for growth and maintaining consistent planting intervals. It relates to the provision of seedling planting equipment.

Long ago, crops were grown by workers forming planting holes in the raised fields and then sowing the seeds of the crops they wanted to plant. However, in recent years, seedlings grown to a certain size have been planted in growth pots on the raised beds to increase the growth rate. Currently, efforts are being made to increase work efficiency.

As described above, the development of tools for planting seedlings in raised beds has become active, and planting devices that allow workers to easily plant seedlings by controlling them with their hands have been developed and used.

doesn't exist.

In the case of Patent Document 1 among the above prior arts, it not only facilitates the health and packaging of the seedling planting device, but also constitutes a spacing adjustment means that can estimate the planting distance, and crops or weeds to be removed at the lower end of the upper pipe. It is characterized by being equipped with a weed removal blade that can pull or cut.

In the case of Patent Document 2, a trowel is made with a simple structure, a hole is drilled so that seedlings can be easily planted, extra soil is prepared around the hole, the seedlings are put in, the seedlings are very easily planted with the extra soil, and the mulching plastic hole is made. It is characterized by providing a planting shovel for seedlings so that it can be filled and covered.

In the prior art as described above, there is no function that allows seedlings to be planted directly on the raised bed from the pot where the seedlings were grown, and there is an addition that provides ease of disassembly and assembly of the device, can supply water, and can specify the planting distance. Although it provides useful functions, the following problems occur.

It is possible to form holes for planting seedlings, but planting seedlings directly has to be done by workers, so it does not help farm workers who are lacking, and not only does work efficiency decrease, workers have to move around a lot, such as digging holes and planting seedlings. Because of this, fatigue increases.

To solve this problem, manual planting devices have recently been developed and provided that allow seedlings to be planted by placing seedlings inside a tubular body and then inserting them into a raised bed and opening them to form a hole.

In this case, forming a planting hole in the raised bed and planting the seedlings can be done at the same time, but the work of supplying moisture and supplying fertilizer for the growth of the planted seedlings must be done separately, which is inconvenient. .

This causes the inconvenience of having to water and fertilize again after planting the seedlings, and because fertilizing is done at the top of the seedlings, it takes a lot of time for nutrients to be delivered to the roots. Due to this, nutrients are not properly delivered to the roots, which hinders growth, as well as causing the planted seedlings to dry out and die before they can grow.

Accordingly, the present invention was invented to solve the above problems, and includes a tubular-shaped planting body 105 having a handle 101 for manipulation at the top and an input hopper 103 for inserting seedlings 102;

A link structure 108 connected to a planting blade 106 forming a hole for planting seedlings in a raised bed at the bottom of the planting body 105 and an operating lever 107 provided on the handle 101;

Depth adjustment means 130 for adjusting the planting depth of the seedlings 102 while maintaining consistency at the lower part of the planting body 105;

Planting spacing control means 150 for controlling the planting spacing of seedlings 102;

A water supply means (160) installed on the upper part of the planting body (105) to supply water to the planted seedlings (102);

Including a fertilizer supply means (170) installed at a position opposite the handle (101) to supply fertilizer (110) downward to the seedlings;

By supplying fertilizer and water together while planting seedlings, it provides ease of growth and maintains a constant planting interval. In addition, the planting depth can be freely adjusted according to the crop, increasing work efficiency and reducing work fatigue. It is possible to achieve the goal.

The present invention not only helps farmers with insufficient labor by enabling planting of seedlings, watering, and fertilizer supply all at once, but also has the effect of significantly reducing workers' workload and reducing fatigue.

The present invention enables planting, irrigation, and fertilization of seedlings at the same time. In particular, in the case of fertilizer, it is placed at the bottom of the seedlings so that nutrients can be directly supplied to the roots of the seedlings after planting, thereby helping the seedlings grow and increasing the survival rate. It has the effect of increasing crop yield.

The present invention facilitates watering, supply of fertilizer, and depth control during the planting process, and the planting spacing can be varied in response to the seedlings to be planted, enabling efficient work, and improving the quality and durability of the planting device. It has various effects, including increasing the external competitiveness of the company.

A crystal sphere 135 is further provided.

It would be natural to maintain the inner part of the operating tube 131 in a state where there is no level difference with the inner diameter part of the planting body 105 to prevent the inserted fertilizer 110 and seedlings 102 from getting caught.

The positioning sphere 135 is a positioning body 137 that accommodates the lower part of the operating tube body 131 and is connected to the lower part of the planting body 105 so that the upper surface 136 can stop further descent at the maximum insertion depth. is provided.

Transverse bridges 138 are protruded on both sides of the lower part of the positioning body 137, and vertical bridges 139 that gradually expand downward are protruded from both ends of the transverse bridge 138, and vertical bridges 139 ), a flat close contact rib 140 is formed at the bottom to ensure good adhesion to the ridge.

On the upper part of the transverse bridge 138, a bar-type lifting guide 141 is protruded upward and connected to guide brackets 142 protruding on both sides of the lower end of the planting body 105 to guide the lifting and lowering of the operating tube 131. In addition, the lifting guide 141 is provided with a lifting spring 143 to assist return after descent.

An adjustment hole 145 in the form of a long hole is formed in the planting body 105, and an intermittent plate 146 is brought into close contact with the outer surface, and then coupled with an intermittent nut 147 and an intermittent bolt 148 inserted into the operating tube body 131. The planting depth is adjusted by adjusting the operating tube 131 in the up and down directions.

The planting spacing control means 150 protrudes a fixing protrusion 152 formed with an intermittent hole 151 so as to protrude upward from one side of the close contact rib 138, and bends a plate-shaped member on the fixing protrusion 152. Then install the roughly “L” shaped adjustment body (153).

The control tube 154 is fixed to the inside of the bent part of the control body 153, and an control bar 156 having a marker 155 at the end is coupled, and the control bar 156 is attached to the outside of the control body 153. It is configured to be controlled by the control knob 157 coupled with the control pipe 154.

The water supply means 160 forms a water supply hole 165 in the upper part of the planting body 105, and a water supply joint 166 to which a water supply hose can be connected is mounted on the water supply hole 165 to supply water when necessary. Connect the hose to supply water.

The fertilizer supply means 170 is equipped with a fertilizer container 172 having a lid 171 on the upper part of the planting body 105 opposite the handle 101, and a discharge port formed below the fertilizer container 172. (173) is connected to a confluence part 175 integrally formed on one side of the planting body 105, and the confluence part 175 has a fixed amount for supplying a certain amount of fertilizer 110 into the planting body 105. Install the feeder (180).

The fixed-quantity feeder 180 is detachably coupled to the drive wheel 182, which is rotatably maintained by the finishing plate 181 at the confluence part 175, and takes over fertilizer from the discharge port 173 to the confluence part 175. Install a metering wheel (185) that discharges downward.

A fertilizer groove 186 capable of receiving fertilizer is formed on the outer surface of the metering wheel 185, and an operating lever 187 is integrally protruded at a position opposite the fertilizer groove 186 on the outer surface of the metering wheel 185. By connecting the upper end of the operating rod 188, which extends from the lifting guide 140 on one side, to the operating link 190, the dosing wheel 185 can be rotated forward and backward in accordance with the lowering and rising of the planting blade 106. Configure it so that

The state of use of the seedling planting device 100 to which the technology of the present invention is applied as described above is as follows.

First, when fertilizer 110 is put into the fertilizer container 172 and the seedling planting device 100 is placed on the raised bed, the adhesive ribs 138 are in close contact with the upper surface of the raised bed to maintain a stable state, and in this state, the handle 101 ) and press it, the operating tube 131 coupled to the lower part of the planting body 105 descends.

As the operating pipe 131 is lowered, the planting blade 106 enters through the ridge. In this process, the positioning tool 135 maintains close contact with the ridge and is connected to the operating pipe 131 and the planting blade. The body 105 is in a descending state.

Therefore, the operating rod 188, which extends from the lifting guide 141 of the positioning sphere 135 and protrudes into the confluence 175, and the steering wheel 185 connected to the operating link 190 are based on the driving wheel 182. The confluence part 175 rotates downward.

That is, initially, the fertilizer groove 186 of the metering wheel 185 is located in the direction of the discharge port 173 and accommodates the fertilizer 110, and the planting body 105 is lowered in the downward direction toward the confluence portion 175. They meet and supply biryeo (110) on the planting day (106).

When the planting blade 106, which has penetrated deeply as described above, is operated to raise the operating lever 107, the connecting piece 114 connected to the lower end of the operating rod 111 rotates the actual blade 106 on one side, The planting blade 106 on the opposite side is opened to both sides starting from the hinge pin 112 at the bottom of the operating pipe 131 by the interlocking pin 115.

In this way, when the planting blade 106 is opened, the fertilizer 110 collected on the planting blade 106 is naturally supplied to the planting groove, and the seedlings 102, which are introduced through the upper part of the planting body 105, are placed and pressed. When the handle is released, the lifting spring 143 included in the lifting guide 141 is contracted and rises due to the force to return to its original state.

At the same time, when the operating lever 107 is released, the operating lever 111, which was raised by the return force of the link spring 116, lowers, and the planting blade 106 connected to it returns to its initial state through the operation of retracting from the open state. do.

As the planting body 105 rises, the operating lever 187 is connected to the operating link 190 connected to the upper end of the operating rod 188 that protrudes upward from the lifting guide 141 constituting the fertilizer supply means 170. As a result, the metering wheel 185 rotates from the position below the confluence 175 toward the discharge port 173 to receive the fertilizer 110 to be added next to the fertilizer groove 186.

After the seedlings 102 are put into the planting groove formed in the raised bed, it is natural that water can be supplied through the water supply hose connected to the water supply tank 166 of the water supply means 160, and when planting at the next location, positioning is determined. The planting spacing control means 150 mounted on the sphere 135 makes it possible to always maintain a constant spacing.

The planting spacing control means 150 controls the spacing by moving the control bar 156 with respect to the control body 153, and determines the distance by positioning the marker 155 on the planted seedlings 102. .

When the planting device 100, which had been lowered after planting the seedlings 102 as described above, is raised, the soil that is spread on both sides by the planting blade 106 when lowered forms the vertical bridge 139 that constitutes the positioning hole 135. It is maintained in a compressed state, and as the pressure decreases as it rises, the soil naturally collapses in the direction of the planting groove and is supplied and covered.

By repeating this operation, seedlings 102 can be planted at regular intervals, and it is possible to freely adjust the planting depth and opening degree of the planting blade 106 in response to the type of crop to be planted.

The planting depth control of the planting blade 106 is achieved by the positioning tool 135 constituting the depth adjustment means 130, and the operating tube ( 131) and the intermittent plate 146 are fixed with intermittent bolts 148 so that the typesetting body 105 and the operating tube 131 are raised and lowered together.

Loosen the intermittent bolt 148 to raise or lower the operating tube 131 with respect to the planting body 105 to adjust the degree to which the planting blade 106 is inserted into the ridge, and then tighten it again to prevent it from moving, thereby damaging the crops. It becomes possible to adjust the depth of the planting groove accordingly.

The degree of opening of the planting blade 106 is controlled by separating the operating rod 111 into an upper rod 121 and a lower rod 122 and controlling it with an adjustment bolt 124 through a long hole 123. By controlling the degree to which the rod 111 pulls the planting blade 106, it is possible to freely adjust the degree of opening of the planting blade 106.

When it is desired to control the amount of fertilizer 110 through the fertilizer supply means 170, it is possible to open the confluence part 175 constituting the fertilizer supply means 170 and then replace the metering wheel 185. This can be realized by replacing the fertilizer groove 186 formed in the metering wheel 185 with a metering wheel 185 of the desired capacity because the size is different.

In addition, in the case of the present invention, the planting body 105 descends and rises while the close contact rib 140 of the positioning tool 135 constituting the depth adjustment means 130 is in close contact with the upper surface of the ridge, forming a planting groove. It can serve as a standard for forming seedlings, allowing seedlings to be planted consistently at a controlled depth even if the worker unintentionally grabs the handle 101 and strongly lowers it.

This invention provides ease of growth by supplying fertilizer and water while planting seedlings and maintains a constant planting interval, as well as freely adjusting the planting depth in response to the crop, increasing work efficiency and reducing work fatigue. It has the advantage of being able to reduce
