DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-film coating apparatus for coating a cultivation area in a field with a multi-film.

[0002]

2. Description of the Related Art Conventionally, various multi-film coating apparatuses for coating a multi-film on a cultivation area in a field have been developed and put into practical use, for example, those disclosed in Japanese Utility Model Publication No. 4-7729. In addition, the applicant filed Japanese Utility Model Application No. 4-46.
No. 495, for example.

[0003] In these multi-film coating apparatuses, in order to prevent the multi-film covering the cultivation area from being peeled off or flicked by the influence of wind or the like, a predetermined position on the multi-film immediately after the coating is applied. (For example, both ends along the coating direction of the multi-film)
Is covered with soil.

[0004] The mechanism for covering the multi-film immediately after the covering is as follows: a soil discharging device for discharging soil from a field and discharging the soil from the upper end, and discharging the soil from the upper end of the soil lifting device. And a chute for guiding the soil to a covering position.

[0005]

Here, in order to reliably cover the multi-film covering the cultivation area, it is necessary to prevent the soil used for the covering from adhering to the inner peripheral surface of the chute, and to prevent It is necessary to make the soil fall smoothly. For this reason, the inclination of the chute in the front-rear direction is set to be steep.

However, the pair of left and right chutes have their upper ends close to each other and the lower ends of the chutes are largely separated from each other, so that these chutes have a gentle inclination in the left-right direction. Therefore, in the case of a soil having a high moisture content or a soil having a high viscosity, these soils may adhere to the inner peripheral surface of the chute when falling in the chute, making it impossible to reliably cover the multi-film. .

Further, when the multi-film coating is performed while the tractor is running in a direction perpendicular to the inclination direction in an inclined field, the earth unloading device and the chute are moved in the left and right direction (movement of the tractor) along the inclination of the field. Direction perpendicular to the direction). Then, the inclination of the chute located on the upper side along the inclination direction in the left-right direction is further increased, and the soil falling in the chute is more easily attached to the inner peripheral surface of the chute.

The soil falling in the chute adheres to the inner peripheral surface of the chute, so that the multi-film cannot be covered sufficiently, and the multi-film covering the cultivation area is peeled off or blown off by the wind or the like. It becomes easier.

[0009]

According to the first aspect of the present invention,
In a multi-film coating apparatus for attaching a multi-film wound in a roll shape to the rear of the moving agricultural machine and pulling out the multi-film to cover a cultivation area in a field,
A lifting device that lifts soil in the field and discharges the lifted soil from the upper end is provided at the rear of the moving agricultural machine, and the soil discharged from the upper end of the lifting device is moved in the traveling direction of the mobile farming machine. A transport body that is transported outward in the left-right direction that is substantially perpendicular to the transport body, a soil drop port for dropping the soil transported by the transport body is provided at an outer end side of the transport body, and an upper end portion is the soil drop port. And a pair of left and right chutes that extend substantially vertically downward and guide the soil dropped from the soil drop opening to a predetermined position on the multi-film covering the cultivation area.

[0010] According to a second aspect of the present invention, in the first aspect of the present invention, the transporting body and the soil dropping port are provided so as to be integrally adjustable in a lateral direction substantially orthogonal to the traveling direction of the moving agricultural machine.

According to a third aspect of the present invention, in the first aspect of the present invention, the transporter is provided so as to be freely adjustable in the left-right direction substantially orthogonal to the traveling direction of the mobile agricultural machine.

[0012]

According to the first aspect of the present invention, the multi-film wound in a roll is drawn out and coated on the cultivation area in the field as the mobile agricultural machine is run. Further, the soil discharged from the upper end portion of the earth-lifting device after being earth-lifted by the earth-lifting device is conveyed to the outside in the left-right direction by the carrier, and falls from the earth fall opening. Then, the soil that has fallen from the soil falling port is guided by the chute and falls to a predetermined position on the multi-film covering the cultivation area, and covers the multi-film. Here, since the soil discharged from the upper end of the lifting device is conveyed outward in the left-right direction by the conveying body, the chute can be installed in a steep state in a substantially vertical direction. Is less likely to adhere to the inner peripheral surface of the chute, the soil is reliably covered on the multi-film, and the multi-film is prevented from being peeled off or blown off by the influence of wind or the like. Also, when the mobile agricultural machine is driven in a direction perpendicular to the inclination direction in the inclined field, the inclination of the chute located on the upper side along the inclination direction is maintained in a steep state.

According to the second aspect of the present invention, the position of the carrier and the soil drop opening are integrally adjusted in the left-right direction, so that the soil of the soil transported leftward and rightward outward by the transporter is adjusted. The amount can be adjusted. For example, by increasing the amount of soil falling from the chute located on the windward side, the multi-film is further prevented from being peeled or fluttered by the influence of wind or the like. Further, when the mobile agricultural machine is driven in a direction perpendicular to the inclination direction in an inclined field, the amount of soil conveyed downward along the inclination increases if no measures are taken. By adjusting the position of the soil dropper to the lower side along the slope, the amount of soil conveyed to the left and right sides by the carrier becomes substantially equal, and the amount of soil conveyed from the pair of right and left chutes is substantially the same. A quantity of soil is dropped.

According to the third aspect of the present invention, when adjusting the amount of soil conveyed to the left outside and the right outside by the carrier, only the position of the carrier needs to be adjusted in the left-right direction. The operation for adjusting the amount of soil conveyed outward in the left-right direction is facilitated.

[0015]

An embodiment of the present invention will be described with reference to the drawings. A three-point hitch 2 is located behind the tractor 1 which is a mobile farm machine.

A spring 1 is mounted between the connecting member 9 and the leveling plate 17 so as to press the tip of the leveling plate 17 against the ground.
8 are provided.

Next, the working machine 4 is provided with a lifting device 19 for lifting a part of the soil in front of the leveling plate 17 in the field and discharging the lifted soil from the upper end thereof. The lifting device 19 includes a lifting case 20 supported by the connecting tool 9 and a lifting case 20.
A lifting belt 21 housed in the inside, a belt drive shaft 22 wound around the upper end of the lifting belt 21 and supported by a lifting case 20, and a diagonally upward rearward from the transmission case 8. A power transmission case 23 extending in the direction;
The belt drive shaft 2 is accommodated in the power transmission case 23 and is transmitted from the transmission in the transmission case 8.
2 and a power transmission unit (not shown) that transmits power to the power transmission unit 2.

Here, a cylindrical body 25 is connected to one end of the belt drive shaft 22 via a joint 24. One end of a rotary shaft 26 is slidably spline-fitted into the cylindrical body 25, The other end of 26 is connected to one end of a rotating shaft 28 via a joint 27. The rotating shaft 28 is supported by a frame 30 via a bearing 29, and a sprocket 31 is fitted to the other end of the rotating shaft 28.

A pair of support shafts 32, 33 having an axis in the left-right direction are attached to the upper part of the earthing case 20, and these support shafts 32, 33 are fixed by R pins 34 attached to both ends thereof. Movement in the left-right direction is restricted. Cylindrical pipes 35 and 36 are slidably fitted to the support shafts 32 and 33, and the pipes 35 and 36 receive the soil discharged from the upper end of the earth lifting device 19. A guide plate 37 extending in the left-right direction and having a substantially U-shaped cross section is fixed. Further, a locking handle 38 for locking the pipe 35 at an arbitrary sliding position by pressing a distal end portion of the pipe 35 against the outer peripheral surface of the support shaft 32 is screwed to the pipe 35. The frame 30 is fixed to one end of the guide plate 37, and the side plate 39 is fixed to the other end.

Next, in the guide plate 37, there is provided a transport body 40 extending in the left-right direction substantially perpendicular to the traveling direction of the tractor 1. The carrier 40 includes a rotating shaft 42 whose both ends are supported by the frame 30 and the side plate 39 via bearings 41, and a pair of right and left screw portions 43 spirally wound around the outer periphery of the rotating shaft 42. , 44. The screw portions 43 and 4
The spiral direction of No. 4 is opposite from the branch portion 45 at the center position along the longitudinal direction of the rotating shaft 42, and one screw portion 43 is inserted into the guide plate 37 from the upper end of the earth lifting device 19. Conveys the discharged soil to the left outside,
The other screw portion 43 conveys the soil discharged into the guide plate 37 from the upper end of the earth lifting device 19 to the right outside. And the rotating shaft 4
A sprocket 46 is fitted to one end of the sprocket 2, and a power transmission chain 47 is wound between the sprocket 46 and the sprocket 31.

At both left and right ends of the guide plate 37, soil drop openings 48 and 49 for dropping the soil transported by the transport body 40 are formed. To the soil drop openings 48, 4
9 and a pair of right and left chutes 50 and 51 extending downward substantially in the vertical direction are fastened and fixed by bolts 52. Since the upper ends of the chutes 50 and 51 are communicated with soil drop openings 48 and 49 formed on both left and right ends of the guide plate 37, the chutes 50 and 51 are connected.
The distance between the upper ends of the shoots is increased, and these shoots 5
The inclination of 0, 51 is steep not only in the front-back direction but also in the left-right direction.

In such a configuration, when the cultivation area in the field is covered with the multi-film 11, the tractor 1 to which the working machine 4 is connected is run in the field that has been previously rotary-tiled. Then, the lifting belt 21 is rotationally driven by the PTO power transmitted from the tractor 1,
Part of the soil in the field is excavated. In addition, the leveling plate 17 which moves while the lower end portion is pressed against the ground is the lifting belt 2.
The cultivation area covering the multi-film 11 is leveled while filling the holes in the portion excavated by 1. further,
As the tread wheel 14 rotates while stepping on the multi-film 11, the multi-film 11 is sequentially pulled out, and the cultivation area is covered with the multi-film 11.

Next, the soil lifted by the lifting belt 21 is fed from the upper end of the lifting device 19 to the guide plate 37.
It is discharged inside. The soil discharged into the guide plate 37 is removed by the rotation of the carrier 40, which is transmitting power via the sprockets 31 and 46 and the chain 47, around the center of the rotating shaft 42.
The papers 3 and 44 convey the paper toward the outside in the left direction and the outside in the right direction. Note that the working machine 4
Is not inclined in the left-right direction, the branch portion 45 is opposed to the center position of the earth-lifting device 19 as shown in FIG.
Then, the soil discharged from the earth lifting device 19 is substantially equal on both sides of the branch portion 45, and the amount of soil conveyed to the left outside and the right outside is substantially equal.

The soil conveyed to the outside in the left-right direction by the screw portions 43 and 44 eventually falls from the soil falling ports 48 and 49, and the soil dropped from the soil falling ports 48 and 49 is shot 5
The multi-film 11 covered by the cultivation area is guided by 0, 51 and falls to both ends along the covering direction on the multi-film 11 to cover the multi-film 11. Here, the soil discharged from the upper end of the lifting device 19 is transferred to the screw portion 4 of the carrier 40.
After being conveyed to the outside in the left-right direction by the third and the fourth, and then to the outside in the left-right direction, the chute 5
Since the chutes 50 and 51 fall into the inside, the upper ends of the chutes 50 and 51 are separated from each other, and the chutes 50 and 51 can be installed in a substantially vertical state. Therefore, the slopes of the chutes 50 and 51 become steep in the front-rear direction and the left-right direction, and even if the soil covering the multi-film 11 contains a large amount of moisture or has high adhesiveness, the soil is not sloping. Adhering to the inner peripheral surface is prevented. For this reason, the fall of the soil on the multi-film 11 is performed smoothly, the soil of the multi-film 11 is surely performed, and the multi-film 11 covering the cultivation area is peeled off or blown off by the influence of the wind or the like. Is reliably prevented.

As shown in FIG. 1, the tail wheel 6 and the chutes 50 and 51 are positioned so that the soil falls on the multi-film 11 covered with the concave groove 53 formed by the tail wheel 6. This further prevents the multi-film 11 from being peeled off or being skipped.

Next, when the tractor 1 is run in a direction perpendicular to the inclination direction in the inclined field, the tractor 1 and the working machine 4 are tilted left and right along the inclination of the field. Therefore, while maintaining the positional relationship between the lifting device 19 and the carrier 40 in the state shown in FIG.
Of the soil discharged from the upper end of the screw portion 44 or 43 located on the lower side along the slope increases, and the amount of soil falling from the chute 51 or 50 located on the lower side along the slope increases. At the same time, the amount of soil falling from the chute 50 or 51 located on the upper side along the slope is reduced, so that the covering of the multi-film 11 becomes insufficient, and the multi-film 11 is peeled off or blown off by the influence of wind or the like. Or to be done.

Then, by loosening the lock handle 38, the pipes 35, 36 are slidable with respect to the support shafts 32, 33, and the pipes 35, 36 are moved downward along the inclined direction as shown in FIG. The pipes 35 and 36 are locked by sliding and tightening the locking handle 38 at that position. A guide plate 37 is fixed to the pipes 35 and 36, the frame 30, the side plate 39, and the chutes 50 and 51 are fixed to the guide plate 37, and the rotating shaft 42 of the carrier 40 is fixed to the frame 30 and the side plate 39. Are supported, the guide plate 37 and the chute 5 are moved with the sliding operation of the pipes 35 and 36.
0, 51, the frame 30 and the like slide integrally downward along the inclined direction, and the fitting dimension between the cylindrical body 25 and the rotating shaft 26 increases.

Then, as shown in FIG.
9, the soil discharged from the excavating device 19 is substantially equal on both sides of the branch 45, and the screw portion of the carrier 40 43, 44 make the amount of soil conveyed outward in the left-right direction substantially equal, and
The amount of soil dropped from 0,51 becomes substantially equal. Therefore, even when the multi-film 11 is covered on a slope, the soil can be surely covered on the multi-film 11, and the multi-film 11 is prevented from being peeled off or blown off by the influence of wind or the like. In addition, the position of the carrier 40 can be adjusted by loosening the lock handle 38 together with the pipes 35 and 36 and the guide plate 37 and the chute 5.
It can be performed by a simple operation of sliding 0, 51, and the like. Note that the inclination of the chute 50 located on the upper side along the inclination direction of the field in the left-right direction is gentler than when working on a flat ground, but a conventional example in which the work is performed on a flat ground. Since the slope is still steep as compared with the above, the adhesion of the soil to the inner peripheral surface of the chute 50 can be prevented even when working on a slope.

In a flat field, the multi-film 11
In the case of coating, the screw body 43 is slid inward by sliding the transport body 40 in the left-right direction and by making the branch part 45 face a position shifted leftward or rightward from the center position of the earth-lifting device 19. Alternatively, the amount of soil discharged to the 44 side increases, and the amount of soil falling from the chute 50 or 51 slid inward increases. Therefore, when the covering operation of the multi-film 11 is performed under a wind blowing condition, the transport body 40 is slid in the left-right direction to cover the windward portion of the multi-film 11 covering the working area. By increasing the amount of soil, the coating operation of the multi-film 11 can be reliably performed.

In this embodiment, the guide plate 37, the chutes 50 and 51, and the frame 30 are also slid integrally when the carrier 40 is slid in the left-right direction. The guide plate 37, the chutes 50, 51, and the like may be fixed to the earthing case 20, and only the carrier 40 may be slid. In this case, the total weight of the sliding member is reduced, and the sliding operation is further facilitated.
