Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a transplanter, in which ridges are formed, and in the multi-cultivation in which the surface of the ridges is coated with a multi-film, The present invention relates to a plant for transplanting a crop such as lettuce to a planting unit at each predetermined position.

(Prior art) Conventionally, in multi-cultivation of this kind of crops, when planting transplanted seedlings, a notch is made in the film with a cutter or the like to open a transplantation portion, and the transplanted seedlings are planted in this opening. However, according to this method, the film covers the transplanted seedling after planting the transplanted seedling, and the heat of the film causes the film to come into contact with the film. Therefore, the cut edge of the film may contact the transplanted seedling and damage the transplanted seedling. Therefore, for this reason, a burner is used to thermally form a planting hole of a predetermined size in the seedling planting portion of the film so that the cut end of the film does not come into contact with the planted seedling.

(Problems to be solved by the invention) The perforation of the planting holes for the film is carried out manually by using a burner, which is not preferable in terms of work efficiency, and the spacing between the planting holes is carried out by a division. There is a problem that the intervals between transplanted seedlings after planting are likely to be uneven, which is not preferable for the subsequent management work.

Therefore, in order to improve the efficiency of seedling planting work, the transplanter is run along the ridges, and the burner is lowered at predetermined intervals to form a planting hole in the film, and the planting hole is planted in this planting hole. It is conceivable to transplant the transplanted seedlings using a container.

However, in this case, when the running speed of the transplanter, the descending interval of the burner, and the transplanting interval of the transplanter are constant, planting holes are drilled at equal intervals, and seedlings are planted in the planting holes. However, in general, the wheels of the transplanter often slip during running, so the intervals between the implant holes may not be constant, and the descending position of the transplanter may not be constant. There is a case where the seedlings are misaligned with the planting holes and the transplanted seedlings cannot be surely transplanted in the planting holes, and the planting holes are drilled while the transplanter is running, and the seedlings are transplanted in the planting holes. This causes a problem that the structure becomes complicated.

Therefore, the present invention has been made in view of such points,
The transplanting machine is stopped at predetermined intervals, and when the transplanting machine is stopped, a planting hole is formed in the film, a planting hole is formed immediately below the planting hole, and the planting hole is formed. The transplanted seedlings can be transplanted into the holes so that the holes and holes can be formed in the film on the ridges at equal intervals, and the holes can be surely transferred into the holes. The purpose of the present invention is to provide a transplanter having a simple structure for transplanting seedlings.

[Structure of Invention]

(Means for Solving the Problems) The transplanting machine of the present invention includes a body frame rotatably mounted on a wheel that runs in the left and right groove portions of a ridge covered with a film, and a body frame that is vertically movable. A perforated body which is provided with the film by thermally forming a planting hole and forming a planting hole immediately below the planting hole, and a vertically movable body body frame provided from the planting hole into the planting hole. And a planting device for planting transplanted seedlings on the body frame, and intermittently stops the traveling of the wheels provided on the main body frame, and lowers the perforated body when the traveling is stopped, and with the ascending operation of the perforated body, And a control mechanism for moving the transplanter downward.

(Operation) In the transplanter of the present invention, when power is transmitted to the left and right wheels by the operation of the wheel drive unit of the control mechanism, the transplanter advances along the ridges, and the transplanter advances a predetermined distance. The signal of the transplanter is stopped by the operation of the wheel drive of the control mechanism.

Also, when the transplanting machine stops moving, the perforated body driving unit of the control mechanism is actuated, and the perforated body is lowered to the transplanting section of the film that covers the surface of the ridge, and the perforated body thermally perforates the perforation holes in the film. At the same time, the planting hole is formed just below the planting hole by piercing on the ridge.

Further, as the perforation body is raised, the implanter drive part of the control mechanism is actuated, the implanter is lowered toward the implanting hole and the implanting hole, and the implanter holds the implant in advance. The seedling is dropped from the planting hole into the planting hole and planted on the upper surface of the ridge.

Then, the implanter is lifted by the operation of the implanter drive unit of the control mechanism, the wheel drive unit of the control mechanism is activated again, and the transplanter is advanced again.

Then, the transplanter, the perforation body and the planter repeat the above-mentioned operation, and the transplanted seedlings are sequentially and stably transplanted into the planting hole through the planting hole on the upper surface of the ridge at regular intervals.

When the chute 90 of the planter 60 is rotated about the horizontal shaft 96 by the towing and rotation of the planter 60, the lower end 97 of the chute 90 is pivoted outward, and the drop port 99 of the planter 60 is opened. Then, the soil block S of the transplanted seedling N supported between the chute 90 and the main body 91 is automatically dropped from the dropping port 99 through the planting hole 152 into the planting hole 153 and planted. In this case, since the planting hole 153 is formed in an inverted conical shape, the inverted conical soil block S is planted in a stable and stable state.

Further, the sector gear 109 is further rotated, the sector gear 109 again meshes with the first output gear 106, and the rotary shaft 124 is rotated via the interlocking gear 123, so that the belt 130 is rotated in the same manner as described above. The rotation shaft 127 is rotated via the belts 133 and 136, and the left and right wheels 11 are rotated again via the left and right belts 133 and 136, so that the transplanter A is advanced along the ridge B while straddling the ridge B. As the transplanter A advances, the fan gear 109 is rotated as described above, so that the fan gear 1 is rotated.
Since the turning piece 112 coaxial with 09 is turned, the turning piece 112 is rotated.
The interlocking piece 114 is pulled and rotated again, and the pair of upper links 61 in the link mechanism 59 of the planter 60 is rotated upward with the first mounting shaft 57 as the rotation center. The rotation of the link 61 causes a pair of rotation links.
The pair of lower links 62 are pivoted upward with the second mounting shaft 58 as a pivot center via 65, and the pair of upper links 61 and lower links 62 are pivoted upward to pivot the pivoting pieces.
A pair of upper link 66 and lower link 67 is rotated upward while 73 is rotated outward with the support shaft 75 as the rotation center. Therefore, the planter 60 has the planting hole 152 and the planting hole 153 of the ridge B.
From above, the drop port 1 of the guide plate 142 of the seedling feeding mechanism 5 is kept in a substantially vertical state as in the case described above.
Although it is pulled up just below 44, the cam 111 is disengaged from the roller 84 of the L-shaped link 82 by the rotation of the fan-shaped cam plate 110, and the operating rod 81 is automatically returned by the return force of the spring 85. , The interlocking rod 78 and the third interlocking piece 88 are pushed to rotate the chute 90 of the planter 60 toward the main body 91 side around the horizontal axis 96, and the chute 90 causes the drop opening 99 of the main body 91 to be soiled. The block S is closed again in preparation for the fall.

Then, the sector gear 109 is further rotated, and the sector gear 109 is disengaged from the first output gear 106, the progress of the transplanter A is stopped, and the sector gear 109 is again meshed with the second output gear 117. Then, as described above, the perforation work for the film F and the ridge B by the perforation body 34 and the planting work by the planting device 60 are performed.

In this way, the transplanter A stops its progress along the ridges B at a predetermined interval, and at the time of this stop, the film F is provided with the planting holes 152 of a predetermined size and the planting is performed. A planting hole 153 is formed at the bottom of the hole 152, and this planting hole is formed.
The soil block S of the transplanted seedling N can be planted in 153.

〔The invention's effect〕

According to the present invention, by the control action of the control mechanism, the traveling of the transplanter is stopped at predetermined intervals, and when the transplanter is stopped, the implantation holes are thermally drilled in the film in which the ridges are covered with the perforations. At the same time, it is possible to surely form a planting hole directly under the planting hole, and it is possible to surely transplant the transplanted seedlings in the planting hole and the planting hole by a planter, and thus, the ridge The planting holes and planting holes can be formed in the film at regular intervals, and the transplanted seedlings can be calmly transplanted into the planting holes and planting holes. Since the machine was stopped and the perforated body and the planter were activated, compared to the case where the transplanted seedlings are transplanted while the transplanter is running, the transplanted seedlings are more surely transplanted into the planting holes, and the transplanted seedlings are more reliable. Function structure can be easily configured Kill.
