Description

A rotary transfer device for moving and lowering a stem crop {Moving down rolling cultivation device of stem crop}

The present invention relates to a rotary transfer device for moving and unloading stem crops, and more particularly, reduces the initial facility investment cost compared to the conventional vine plant stem attracting device, and includes a rail and a rotary transfer means, an attracting loop and a pulley roller. Through more convenient management of vine plant cultivation facilities, labor and labor costs can be reduced, and stem crops that can be moved and unloaded can be moved and unloaded while minimizing the stress on plants, thereby maximizing the marketability and yield of agricultural products. It relates to a rotary transfer device.

In general, in order to cultivate vines such as cucumbers, pumpkins, tomatoes, paprika, etc., the plants are harvested by hanging the stems of the plants in a manned loop of a predetermined length.

At this time, since the vine grows continuously, it continuously attracts and moves the position of the plant stem.

As a method of attracting the stems of vines in the related art, vertical attraction method, inclined attraction method, and wet-heart cultivation method are used.

In particular, vine plants grow continuously, whereas cultivation facilities such as a normal house have a limited height. A method of vertical attraction while moving in the longitudinal direction of the gyrus is also used.

In relation to this, the technology of 'Patent Document 1' has been proposed, and the 'Patent Document 1' is provided with an inducer line for attracting stems of vines, and a wire belt disposed in a horizontal direction with respect to the ground, and a wire By manually driving the stem inducer, including the rotating part connected to the wire belt to move the belt, and the manual driving part connected with the rotating part and gear to rotate the rotating part, the control device malfunctions or excessive rotation caused by low plant load. The safety level can be improved by preventing malfunctions such as rooting of vines, and the installation cost can be reduced by 40% compared to when the existing electric motor-driven stem attracting device is installed. , it is possible to reduce labor costs among operating costs by lowering the stems in units of individual plants and then moving the stems in units of rows at once. It's about incentives.

However, in the conventional device for attracting vines including 'Patent Document 1', in order to vertically entice the stems of vines while moving in the longitudinal direction of the ridge, the vines are lowered individually, and then the stems of vines.

a first rotating body 240 coupled to the first fixed shaft and moving along the outer surface of the rail;

It characterized in that it is configured to include; a rolling part 250 that is coupled to the second fixed shaft and moves along the outer surface of the rail.

Specifically, the first fixed shaft 220 having a predetermined length is formed on the upper side of the vertical portion 210 having a predetermined size.

In addition, a second fixed shaft 230 having a predetermined length is formed horizontally at a position spaced apart from the first fixed axis by a predetermined distance.

At this time, the vertical elastic part 210 , the first fixed shaft 220 , and the second fixed shaft 230 are formed of a material having elasticity. to prevent escape.

At this time, the first rotating body 240 moving along the outer surface of the rail is coupled to the first fixed shaft, and a through hole for penetrating the first fixed shaft is formed, so that the first fixed shaft is penetrated here. .

In addition, the rolling part 250 is coupled to the second fixed shaft and moved along the outer surface of the rail. Like the first rotating body, a through hole for penetrating the second fixed shaft is formed therein. It will pass through the fixed shaft.

The first rotating body 240 is coupled to the first fixed shaft to move along the outer surface of the rail, and the rolling part 250 is coupled to the second fixed shaft to move along the outer surface of the rail.

At this time, by forming the rolling part to be smaller than the diameter of the first rotating body, it is possible to lower the manufacturing cost, and since it is formed on the second fixed shaft, it serves to roll when the first rotating body rotates. will become

In addition, as shown in the figure, the rolling part has a cylindrical shape and is inserted into the second fixed shaft.

On the other hand, as shown in Figure 2, the pulley roller 300 is fixed to one side of the first rotating body 240, it may be fixed to the left side of the first rotating body as shown in the left figure, and the first rotating body as shown in the right figure. It means that it can be fixedly coupled to the right side of the rotating body.

As a result, through the configuration as described above, the rotary transfer means 200 is moved along the rail 100 .

On the other hand, according to an additional aspect, by forming a gear on the first rotating body and gear-coupled, to guide the movement along the rail.

At this time, the pulley roller 300 is characterized in that it is coupled to one side of the rotary transfer means.

Specifically, the pulley roller 300 is coupled and fixed to one side of the first rotating body 240 .

1, the pulley roller is coupled and fixed to the first rotating body.

At this time, as shown in Figure 11, the pulley roller 300,

The engaging loop 400 seated on the outer periphery is engaged while rotating along the outer periphery of the pulley roller 300, the engaging portion 310 configured to be engaged;

It is characterized in that it comprises a; guide part 320 for guiding the inducement loop to prevent the induction loop 400 seated on the outer periphery from being separated from the outer periphery.

Specifically, a plurality of locking fastening parts 310 are formed at regular intervals so that the attracting loop 400 seated on the outer periphery is caught and fastened while rotating along the outer periphery of the pulley roller 300. It is a self-contained fact that the member is to be latched, and at least one is formed inside the pulley roller.

At this time, the guide part 320 performs a function of guiding the inducement loop to prevent the attracting loop 400 seated on the outer periphery from being separated from the outer periphery.

Therefore, it is natural to form it higher than the height of the engaging member formed in the induction loop.

And, the induction loop 400 is seated on the pulley roller 300 to attract the stem of the vine, and when the pulley roller rotates, it performs a function of lowering the stem on one side.

On the other hand, the manned loop 400 is configured in the form of a loop and is fastened to the pulley roller 300 , and while rotating by the pulley roller 300 , a loop rotation track having a tension side and a relaxation side in a direction perpendicular to the ground is formed. Attracting the stem of the vine plant so that the stem of the vine plant is continuously lowered vertically from the relaxation side downward along the loop rotation trajectory along the loop rotation trajectory by attracting the growth of the stem of the vine plant to the relaxation side. is characterized.

In order to perform the above function, the induction loop 400 is,

It is characterized in that it further includes a plurality of engaging members 410 formed to be spaced apart from each other by being coupled to the induction loop so as to be engaged with the engaging portion during rotation along the outer periphery of the pulley roller 300 .

As shown in FIGS. 8 and 10, the manned loop is configured in a loop shape and fastened to the pulley roller, and while rotating by the pulley roller, a loop rotation track having a tension side and a relaxation side in a direction perpendicular to the ground is formed. and performs the function of attracting the stems of vines.

Therefore, when the worker pulls the manned loop, the manned loop rotates, and the pulley roller rotates accordingly, thereby moving along the rail and lowering the stem of the vine stems attracted to the manned loop at the same time. will be.

Accordingly, when the first rotating body is rotated, it is moved in the pulling direction, so that it is possible to move a specific vine under dense cultivation.

On the other hand, as shown in Figure 3, according to an additional aspect, the first rotating body 240,

By further including a bearing 260 therein, it is possible to perform smooth rotation by the bearing.

That is, when the manned loop is pulled, the bearings are formed on both sides of the first rotating body, since smooth rotation can be performed at the same time to reduce the burden on the operator.

On the other hand, as shown in Figure 4, according to another additional aspect, the first rotating body 240,

It is characterized in that the slip prevention part 270 is formed by coating or mounting a silicone or rubber material on the surface.

That is, by coating or mounting a silicone or rubber material having a high coefficient of friction on the surface, the anti-slip part is constituted to prevent slip.

On the other hand, as shown in Figure 5, according to another additional aspect, the first fixing shaft 220 or the second fixing shaft 230 at the end of the anti-separation screw 280; is formed, 6, after inserting the rotating body into the fixed shaft by coupling the separation prevention nut portion 285 to the formed separation prevention screw thread portion, it is characterized in that it is prevented from falling off at the inserted position.

That is, when the rotary type transfer means is continuously moved along the rail, the first rotating body and the rolling part naturally fall off from the first fixed shaft and the second fixed shaft. The prevention screw thread part and the escape prevention nut part are configured.

On the other hand, as shown in FIG. 7 , according to another additional aspect, by forming a separation prevention part 290 at the end of the first fixed shaft 220 or the second fixed shaft 230; After inserting the rotating body and the rolling part into the first fixed shaft and the second fixed shaft, it is characterized in that it prevents falling off at the inserted position.

As a configuration different from the configuration of FIGS. 5 to 6, the first rotating body and the rolling part are inserted into the first fixed shaft and the second fixed shaft by configuring an arrow-shaped separation prevention part at the ends of the first and second fixed shafts. In this case, it is inserted naturally, and then, due to the sharp shape of the arrow, it is to be prevented from falling off at the current position.

Next, the operation process will be described in detail.

When the manned loop is pulled, the pulley roller rotates, and the rotary type transfer means coupled thereto rotates and moves.

At this time, as the manned loop is configured in a loop shape, a loop rotation track having a tension side and a relaxation side in a direction perpendicular to the ground while rotating by the pulley roller is formed.

Therefore, when attracting the stem of the vine plant to the relaxed side of the attracting loop, regardless of the number of rotations, the stem of the vine plant that is attracted to the relaxed side of the attracting loop and grows upward can be continuously lowered. .

The shift-down cultivation farming method described in the present invention refers to a farming method that implements horizontal shift and vertical shift.

This has the effect of dramatically reducing the labor force compared to the conventional vertical lowering farming method, which requires repeatedly winding an induction loop of about 49,000M or more per house for each crop plant, and moves it to the desired location regardless of dense cultivation. will have the effect of

Conventional technologies have in common to rewind the lure line after the end of slicing, so it is only a labor force distribution rather than a labor reduction, and as the practical utility is insignificant, it is not practically commercialized, so the industrial applicability is significantly lowered. .

In addition, since scissors are used during operations such as shoot picking or cotyledon removal, serious problems occur frequently in that the attracting loop is broken. It is also true that the problem that the line is broken actually occurs and it is difficult to actually commercialize it.

On the other hand, the present invention provides the advantage of being able to perform a moving operation and a lowering operation with a low installation cost rather than the existing high cost installation cost.

In addition, since there is no need to rewind the manned line by using the infinite rotation of the manned loop, it is an excellent technology that can solve the disadvantages of cost increase and labor cost increase due to manned replacement and rewinding at once. .

Even if the prior art has the same object as the present invention in terms of labor saving, when the lure line that was continuously unwound during the cropping is finished, the inducement line must be rewound to prepare for the next cropping and rewinding Since work is involved, it is only a labor force distribution, not a labor reduction in reality.

Taking cucumbers as an example, in general, about 1,400 cucumber stems are planted in one house, and the cucumber stems grow on average about 35M or more. M (35M × 1,400 bags = 49,000M) or more manpower is required to wind up each small machine.

Therefore, the present invention, which does not require replacement and rewinding of the lure line, is an excellent technology that provides an overwhelmingly superior labor saving effect compared to the prior art.

On the other hand, the present invention is a moving descending cultivation method, and has a structural feature of moving the attracting loop in one direction according to the growth rate of the stem, rotating it infinitely, and lowering the stem as much as the stem grows at the same time.

The present invention is configured so that a vertically rising stem is attracted from the relaxation side of the attracting loop. As it descends slowly along with the stem, the stress on the stem during the stem lowering operation is minimized.

In conclusion, in the present invention, only a very small load that holds the stem acts on the induction loop, and even if the stem grows, the attracting loop rotates as much as it grows to lower the stem, so the load on the attracting loop itself is very small, In contrast to the advantages of improving productivity and crop quality by minimizing stress on vines, in the case of the prior art, as the stem grows, it is pulled upward and then moved laterally, so the load acts considerably. There is a disadvantage that a wound occurs on the stem, which leads to a decrease in productivity and a decrease in quality.

According to the present invention, labor and labor costs can be reduced by reducing the initial facility investment cost compared to the conventional vine plant stem attracting device and managing the vine plant cultivation facility more conveniently through rails, rotary transfer means, induction loops and pulley rollers. In addition, the effect of moving and lowering work is achieved while minimizing the stress on the plant.

In addition, regardless of the cultivation environment, it is possible to provide a device capable of automating the shifting and lowering cultivation, which has been done manually in the past.

In the above, the present invention has been described based on the drawings shown in the drawings, but this is only exemplary, and various substitutions, modifications and changes are possible without departing from the technical spirit of the present invention. it is not going to be
