The present invention relates to a movable mulching machine for laying vinyl or aluminum foil on an orchard or field, and more specifically, a reinforcing bar is coupled to an upper surface of the rear end of the "c" shaped main frame, which is open toward the rear, and on the side thereof. A wheel shaft is coupled, and a pair of air wheels are provided on the wheel shaft, and a roll shaft capable of rotatably mounting a roll rolled with vinyl or foil is detachably coupled, and left or right at the front end of the main frame. By having a handle biased to either side of the, it can be easily moved on the rough orchard floor, and the handle is biased to one side to facilitate the rotational movement and to prevent falling objects caused by contact with the handle during the movement. It relates to a movable mulching machine, as long as possible.

In general, crops, in particular, weeds to prevent weeds from growing, to prevent evaporation of moisture in the soil, and to cover the soil in the soil in order to prevent the loss of soil in the rain and keep the soil.

In addition, in the case of fruit, the lower side of the fruit toward the ground is insufficient in the amount of insolation, which results in a decrease in sweetness due to the late ripening than other parts, and its color also has a problem of inferior mercury due to the lack of ripening color. To solve the problem, the orchard is laying tinfoil where sunlight can be reflected along the ground where the fruit is planted.

For example, in an apple garden, sunlight falling down to the ground effectively ripens the top of the apple to increase its sweetness and gives the apple its own red color. Not only will it become thinner, but sugar will also fall.

Therefore, the sunlight is also applied to the lower part of the apple so that the apples are evenly aged so that the aluminum foil is laid on the ground where the fruit is planted. The sunlight reflected on the aluminum foil is irradiated on the lower part of the apple to promote ripening of the lower part of the apple.

However, in order to lay vinyl or aluminum foil, the other person must grab the rolled member and pull it to the other end of the field while holding the roll of the rolled member such as vinyl or aluminum on one side of the orchard. Because it is difficult for one person to support the roll that is being rotated, many people have to perform a task, which requires a lot of manpower.

Accordingly, the vinyl mulching machine developed to efficiently perform the mulching operation as described above is disclosed in Korean Utility Model Model No. 97-48705.

The vinyl mulching machine is a structure that covers the vinyl on the ground while moving directly, and the four front and rear blades and both vinyl pressing wheels and vinyl mounting rods and handles are provided to facilitate mulching, but the structure is complicated. And, since the weight of the vinyl mulching machine equipped with a rolled vinyl roll is heavy, there is a problem that the movement operation is not easy.

The vinyl roll is wound around the outer surface of the cylindrical paper tube, and because the inner diameter of the paper tube is larger than the outer diameter of the vinyl mounting rod, the rotation of the paper tube and the vinyl mounting rod is not accurately synchronized with each other, and thus, the release of the vinyl is controlled. Not only is this easy, but both ends of the vinyl mounting rod are caught by the hook, so when the vinyl is released, the vinyl sticking rod cannot be fixed before and after. There is a disadvantage that can not support.

Therefore, the agricultural mulching vinyl support of a new structure to solve the disadvantages of the vinyl mulching machine is disclosed in Utility Model Registration No. 0385207, wherein the agricultural mulching vinyl support is a rotary tube that is mounted with a vinyl roll ( The bobbin is coupled to both ends of the "vinyl mounting rod" of the vinyl mulching machine, the outer diameter of the bobbin is almost the same as the inner diameter of the vinyl roll branch pipe, that is, the inner peripheral surface of the branch pipe contact the bobbin, The vinyl roll and bobbin are rotated together in the case of seasighting, so it is possible to constantly adjust the quality of the vinyl.

However, while the mulching vinyl support for agriculture has a simple structure and the unwinding of the vinyl has a certain advantage, unlike the vinyl mulching of the Utility Model No. 97-48705, it is not a mobile type fixed, the mulch is one side of the field such as a field In the state fixed to the end has the disadvantage of covering the patina after loosening the vinyl to the other end of the pat at a time.

In other words, in the state of unwinding the vinyl, or after removing the vinyl over the entire length of the tomb and before fixing the vinyl to the tomb, if the strong wind blows, the vinyl will be swung and not easy to fix to the tomb. When replacing the roll there is a problem that the removable tube is not easy to attach.

The present invention was devised to solve all the problems of the conventional agricultural mulching machine, it is possible to easily mulch operation while moving the mulching machine even in the uneven ground, such as a field or orchard, it is easy to replace the vinyl roll Rather, it is an object of the present invention to provide a movable mulching machine that can easily rotate the mulching machine 180 ° in order to continue the mulching operation for the adjacent ridge or adjacent superheat.

The object of the present invention is achieved by a handle that is coupled to the left and right reciprocating movement, an upwardly open " U " bushing capable of freely detaching the roll shaft, and an air injection wheel.

The movable mulching machine of the present invention includes a main frame, a reinforcing bar coupled to the rear end of the main frame to reinforce its rigidity, a wheel shaft for coupling the wheels, a pair of wheels coupled to the wheel shaft, and a main frame. A pair of fixedly coupled bushing holders, " U " bushings fixedly coupled to the inner surface of each bushing holder, a roll shaft having both ends rotatably and detachably coupled to two opposite bushings, and one side of the main frame It consists of a handle and the like coupled to the flow, looking at each as follows.

The main frame is made of a pipe or rod, etc., as a main body of the mulching machine, and consists of a straight center bar and a pair of side bars extending from the left and right ends of the center bar to the rear side, respectively. A roll shaft, through which a member to be wound such as aluminum foil or the like penetrates into the hollow of the roll wound on the outer circumferential surface of the branch pipe, serves as a supporting frame to be mounted.

Reinforcement bar, both ends are fixedly coupled to the upper end of the rear end of the side bar constituting the main frame, respectively, and serves as a reinforcing material to prevent deformation or flow of the rear end, which is the free end of the main frame side bar.

In this case, the reinforcing bar may be configured in the shape of a straight bar, it is also preferable to manufacture in a downward open type "c" shape so as not to be caught in the stone roots that may be on the ground or tree roots rising above the ground.

Wheel shafts are respectively coupled to the outer side of the rear end of the main frame side bar, and serves as a rotating shaft of the wheel to allow the mulch of the present invention is movable.

The wheel is composed of a wheel which is rotatably coupled to the rear end of the main frame side bar, respectively, and a tire which is detachably coupled to the outer circumferential surface of the wheel and into which air is injected. It is possible to use wheels made of rubber or synthetic resin, that is, do not need air injection, but because of uneven ground of fields or orchards, air injection with elastic force by air is required for smooth movement on such ground. Preference is given to using tires.

The bushing holder is a plate-like support or coupling member that is coupled to the center of each side bar of the main frame and serves as a bracket for engaging the bushing on which the roll shaft is mounted. The pair of bushing holders are located at the center of each side bar. It is fixedly coupled to face.

The bushing is formed with a "U" -shaped seating groove so that both ends of the roll shaft can be freely mounted or separated in the up and down directions, and are fixedly coupled to each of the opposite inner surfaces of the two bushing holders.

Both ends of the roll shaft are rotatably inserted on the inner surface of the seating groove of the bushing in a state in which the rolled member is penetrated to the outer circumferential surface of the branch pipe, that is, through the hollow portion of the roll.

At this time, the outer diameter of the roll shaft is smaller than the inner diameter of the branch pipe, which minimizes the flow between the roll shaft and the branch pipe, and simultaneously couples a pair of bobbins inserted into both ends of the inner circumferential surface of the branch pipe so that the roll shaft and the branch pipe can be rotated together. It is also preferable, in this case, it is preferable that the bobbins are movable along the outer circumferential surface of the roll shaft in the axial direction and at the same time be temporarily fixed to a specific position.

That is, the length of the branch pipe is different depending on the width of the member to be wound, so that the distance between the two bobbins respectively inserted at both ends of the inner circumferential surface of the branch pipe can be adjusted so that all branches having different lengths can be used.

The handle is a hand-held portion for moving the mulching machine of the present invention. The handle is a straight main handle parallel to the center bar of the main frame, and extends from the left and right side ends of the main handle to the rear side to be parallel to each other. The rear end is composed of a pair of auxiliary handles that are fluidly coupled to the center bar of the main frame to form a rear open " c " shape like the main frame.

That is, the handle is in a state capable of left and right flow along the axial direction on the central portion of the main frame, that is, if necessary, the position of the handle can be freely changed along its axial direction on the outer peripheral surface of the center bar, When the wound member is placed on the ground along the fruit tree, the handle is moved away from the fruit tree to prevent the fruit falling from the fruit branch to the ground, and the mulch machine is rotated for mulching of the adjacent fruit tree. When doing so, it is possible to rotate the mulching machine more easily by using a handle biased to one side on the main frame center bar.

The details of the purpose and technical constitution according to the present invention, including the effect thereof, will be clearly understood by the following description with reference to the drawings showing preferred embodiments of the present invention.

1 is a perspective view of the present invention mulching machine, Figure 2 is an exploded perspective view of the present invention mulching machine.

As shown, the movable mulching machine of the present invention includes a straight center bar 11A that is straight in the left and right directions, and a pair of straight lines that extend from the ends of the center bar 11A to the rear side and are parallel to each other. A “c” shaped main frame 11 which is made up of a side bar 11B and is opened rearward;

Reinforcing bars 12 having both ends coupled to rear ends of the two side bars 11B constituting the main frame 11;

Wheel shafts 13 having both ends coupled to the outer side surfaces of the rear ends of the two side bars 11B constituting the main frame 11;

A wheel 14 having a central portion rotatably coupled to each of the rear ends of the main frame 11 and the side bars 11B;

A pair of plate-shaped bushing holders 15 fixedly coupled to the outer peripheral surface of the center portion of each side bar 11B of the main frame 11 so as to face each other;

A pair of " U " bushings 16 fixedly coupled to respective opposing surfaces of the two bushing holders 15 and facing each other;

Roll shafts 17 having both ends rotatably and detachably coupled to inner surfaces of the two bushings 16;

The linear main handle 18A parallel to the center bar 11A of the main frame 11 and the left and right side ends of the main handle 18A extend rearwards to be parallel to each other, and the rear end portions of the main frame 11A are parallel to each other. A handle having a rear open " c " shape like the main frame 11, comprising a pair of auxiliary handles 18B coupled to the center bar 11A of the frame 11 so as to reciprocate and rotate left and right. 18;

The main frame 11 is composed of a pair of fixing rods 19 which are respectively coupled downward to the lower end of the outer peripheral surface of the center bar 11A and serve as fasteners for the mulching machine to the ground.

At this time, the bushing holder 15 is fixedly coupled to the outer peripheral surface of the central portion of the side bar (11B), the simplest structure can be a flat plate, but may also have a variety of shapes as necessary, for example, in FIG. As shown, it may have a "b" shaped cross-sectional structure consisting of a vertical plate 15A in the vertical direction and a horizontal plate 15B coupled in a horizontal rectangle at the lower end of the vertical plate 15A.

When the vertical plate 15A and the horizontal plate 15B are configured as described above, the bottom surface of the outer circumferential surface of the side bar 11B is coupled to the top surface of the horizontal plate 15B for stable coupling with the main frame side bar 11B. At the same time, the outer end surface of the outer circumferential surface of the side bar 11B is preferably coupled to the inner surface of the vertical plate 15A, but the horizontal plate 15B may be coupled to the upper surface of the outer circumferential surface of the side bar 11B. have.

In addition, the bushing 16 may be directly coupled to the inner surface of the vertical plate 15A of the bushing holder 15. However, the upwardly open bushing case 15C having the “U” -shaped groove formed therein may be connected to the vertical plate 15A. It is more preferable in terms of appearance quality that the first coupling to the inner surface and then inserting the bushing 16 into the inside of the bushing case 15C.

In addition, the reinforcing bar 12 may be configured in a straight line, but in order to prevent possible contact interference with stones or the like that may be on the ground during the movement of the mulching machine, as illustrated, the main bar 11 center bar 11A. 12) parallel to the main reinforcement bar, and the auxiliary reinforcement bar (12A) extending downward from each end of the main reinforcement bar (12A), respectively, the lower end of which is fixedly coupled to the rear end of the side bar (11B) of the main frame (11). 12B) may be configured to have a downwardly open "C" shape.

That is, since the main reinforcing bar 12A is higher from the ground than the case where the reinforcing bar 12 is manufactured in a straight shape, the possibility of interference with the ground becomes less, so that the smoother movement is possible. do.

The roll shaft 17 has a structure longer than the length of the branch pipe P on which the wound member M is wound, and the roll shaft 16 penetrating the inner diameter portion of the branch pipe P has both ends at both sides of the branch pipe P. Protrudes, but the outer diameter of the 17 is smaller than the inner diameter of the branch pipe (P).

Therefore, when the wound member M is unwound while being penetrated through the roll shaft 17, the branch pipe P and the roll shaft 17 cannot rotate together, and the branch pipe P rotates normally around the roll shaft 17. FIG. The paper tube P rotates and rotates irregularly about the roll shaft 17 located in the eccentric position.

In other words, the wound member M, such as vinyl or aluminum foil, wound around the outer circumferential surface of the branch pipe P is not fixed unevenly.

In order to solve the above disadvantages, as shown in Figure 4, it is detachably coupled to the roll shaft 17 a pair of bobbin 17A that can be inserted without flow in the inner diameter portion of the branch pipe (P). desirable.

The bobbin 17A has a cylindrical body 17A1 which can be fixedly coupled to the roll shaft 17 by a tightening bolt B in a state where the roll shaft 17 is penetrated, and along an outer circumferential surface of the central portion of the cylindrical body 17A1 in the axial direction. Along the outer circumferential surface of the inner body 16A1-1 of the body 16A1 divided into the protruding annular flange 17A2 and the inner and outer bodies 16A1-1 and 16A1-2 separated by the flange 17A2. It is formed in the axial direction at regular intervals and consists of a plurality of ribs (17A3) the outer end surface is in contact with the inner peripheral surface of the branch pipe (P).

That is, when the branch pipe (P) is coupled to the roll shaft (17) provided with the bobbin (17A) as described above, both side end surfaces of the branch pipe (P) are flanges (17A2) of both side bobbin (17A), respectively. In close contact with the inner surface, both ends of the inner circumferential surface of the branch pipe P are in contact with the front end surface of the rib 17A3 of the bobbin 17A. When the wound member M is unwound, the roll shaft 17 and the branch pipe ( P) can be rotated together and, accordingly, can be released constantly according to the pulling force of the wound member (M).

The mulching machine of the present invention configured as described above is a device used in a field or orchard, and the ground of the field or orchard is most of the case that is not flat bar. The part which touches the ground becomes the lower surface of the main handle of the wheel | wheel 14 and the center bar 11A of the main frame 11, and the handle 18.

Therefore, when the mulching machine of the present invention is placed on an inclined ground, the mulching machine does not stop where it stops and rolls. It is preferable to provide a means for preventing the mulching machine to stand safely in one place.

For example, the linear fixing rods 19 are downwardly coupled to both sides of the bottom surface of the center bar 11A of the main frame 11 opposite to where the wheels are coupled, and the lower end of the fixing rod 19 is lightly coupled. By being fixed to the photographic surface, the mulching machine may be stably stopped.

As described above, the present invention movable mulching machine is movable to the ground side because it is free to change the coupling position of the handle in the horizontal direction perpendicular to the left and right direction, that is, the moving direction of the mulching machine. In addition to preventing or minimizing the fall and damage caused by contact with fruits, the mulching machine can be easily rotated in the opposite direction for mulching to adjacent fruit trees after the mulching work on a series of overheating lines. By combining the air-injection wheels, there is an advantage that can be easily moved to absorb the shock smoothly even on the ground of the orchard or field uneven due to stones or foreign matter.
