[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
[0012]
FIG. 1 is a front view of the bulb planting apparatus, FIG. 2 is a sectional view taken along the line AA, and FIG. 3 is a sectional view taken along the line BB. 1 to 3, a bulb planting apparatus 1 includes a holding means (holder 5) for holding an object to be planted W such as a bulb or a seed pod, and the planting object W is taken out from the holding means 5 and planted in a field. The planting means (planted body 7) to be attached and the holding means 5 are transported from a position where the planting object W is loaded into the holding means 5 to a position where the planting means 7 takes out the planting object W from the holding means 5 The holding means 5 includes a holding member 22 that comes in contact with the outer peripheral surface of the planted object W loaded while being elastically deformed, and is loaded by the holding member 5. The planting object W is configured to be held so as not to change its posture.
[0013]
Therefore, in the bulb planting apparatus 1 configured as described above, when the planting object W such as a bulb or a seed pod is loaded on the holding unit 5, the holding member 22 of the holding unit 5 is loaded. It contacts while elastically deforming along the outer peripheral surface, and holds the planted object W loaded so as not to change its posture. The planting object W loaded and held in the holding means 5 is transported by the transporting means 3, and the planting object W transported to the set position is taken out from the holding means 5 by the planting means 7 and planted in the field. . In this way, in the field, without any special preparation steps before planting, the field can be placed in a predetermined posture by simply loading the holding means with planting objects such as bulbs such as seed garlic and moss such as seed buds. It is possible to plant bulbs, mosses and the like efficiently and accurately.
[0014]
The holding means 5 is configured so that the planting object W can be loaded from above at the position where the planting object W is loaded, and the planting object W is placed downward at the position where the planting means 7 takes out the planting object W. Further, at this time, a space (gap G) is formed in which the planting means 7 enters the holding portion of the planting object W of the holding means 5 from above and can move downward. The planting means 7 is provided with an engaging portion that engages with a part of the planting object W. As a result, the planting object W is pushed and loaded from above the holding means 5, and the planting means 7 moves from above the holding means 5 and descends in the holding means 5, at this time. Then, the engaging portion of the planting means engages with the upper part of the planting object W held by the holding unit 5 and pushes the planting object W downward. The taken-out planting object W is held in a posture in which the upper part engages with the engaging portion of the planting means and is taken out and brought into the soil and planted.
[0015]
The holding member 22 of the holding means 5 can be made of a foamed material such as sponge, but as shown in the figure, the elastic deformation is planted so that the hair tip faces the loading site of the planting object W. Even if it is composed of a large number of napped bodies, it is possible to hold the planting object accurately so that the posture of the planting object does not change, and the planting means can accurately hold the planting object from the holding means. Can be taken out.
[0016]
The conveying means 3 is configured to rotate up and down, and the planting object W is loaded into the holding means 5 at the upper part of the circumference, and the planting means 7 takes out the planting object W from the holding means 5 at the lower part of the circumference and enters the field. By adopting the planting configuration, the planting object W can be loaded onto the holding means 5 at a high position from the farm scene S. Therefore, when the planting object W is loaded manually, the loading operation is easy and efficient. Since the planting means 7 can take out the planting object W from the holding means 5 at a position close to the farm scene S, the planting means can be taken out from the holding means 5 and then into the soil of the field. The stroke in which 7 takes the planting object W is shortened, and the posture disorder in the stroke is less likely to occur, and the planting accuracy is improved. Moreover, the operating range of the planting means 7 can be reduced, and the body can be made compact.
[0017]
The planting means 7 is provided with an engaging portion that engages with a part of the planting object W at the tip 7 a, and the tip 7 a of the planting means 7 is above the planting object W held by the holding means 5. Is engaged with the upper part of the planting object W and descends into the soil of the field, so that the planting means 7 takes out the planting object W from the holding means 5 in the holding posture and enters the field. It is designed to be planted.
[0018]
In addition, when the holding means 5 is fixed to the conveying means 3 configured as described above and circulates, the holding means 5 places the planting object W from above at the position where the planting object W is loaded as described above. When the planting means 7 is configured to be able to be taken out at the position where the planting means 7 takes out the planting object W, the planting object W can be held when being loaded into the holding means 5. The posture and the holding posture of the planting object W when taken out by the planting means 7 are upside down. Therefore, when loading into the holding means 5, the planting object W is loaded into the holding means 5 in a posture in which the upper side after planting is the lower side. Then, when the holding means 5 is transported to a position where the planting means 7 takes out the planting object W, the holding means 5 is turned upside down when held at the upper part of the transport means 3 and is held by the holding means 5. The planting object W to be planted has an appropriate vertical posture, and the planting means 7 takes out the planting object W in this posture and implants it in the field.
[0019]
Further, the bulbous planting device 1 is configured to be mountable on a self-propelled machine, so that it can be planted continuously while moving in the field.
[0020]
The configuration of the example will be described in detail. The chain 3 as a conveying means is hung around two sprockets 11 and 11 that are arranged at substantially the same height, one of which is driven to rotate and the other is driven to rotate, and a guide plate 12 that is arranged substantially horizontally below. It is provided to rotate. The guide plate 12 is a guide that horizontally feeds the chain 3 at a lower position close to the farm scene S. Thereby, the conveying means includes an upper lateral movement part between the two sprockets 11, a lower movement part continuing downward from the right end thereof, a lower lateral movement part below the guide plate 12 adjacent to the farm scene S, and an upper part. The lateral movement part has a substantially triangular orbit around the upper movement part that rises obliquely. As will be described later, the holder 5 includes a holding member 22 made of a raised body or the like that comes in contact with the outer peripheral surface of the planted object W loaded while being elastically deformed, and is fixed to the link of the chain 3.
[0021]
The implant 7 is freely attached to a shaft 14a attached to the distal end portion of a drive arm 14 that is attached to a drive rotary shaft that projects from the support frame 13 and rotates, and a support shaft that projects from another part of the support frame 13. The rotating arm 15 is rotatably attached to a shaft attached to the tip of the rotating arm 15 so that the tip 7a of the implant 7 draws a vertically elliptical locus T by the driving rotation of the driving arm 14. Operates up and down. And the front-end | tip part 7a of the implantation body 7 sets to the positional relationship which passes the holding | maintenance part of the planting target W of the holder 5 in the lower position of the chain 3 from the top to the bottom, and transfer of each holder 5 by the chain 3 By operating the driving arm 14 in synchronism with the movement, the tip 7a of the implant 7 pushes out the planting object W held by the holder 5 from the top to the bottom while maintaining the posture, and the implant 7 With the momentum of the operation, the planted object W is brought to the farm scene S while being held by the tip 7a in the posture and pushed into the soil for planting.
[0022]
When the planting means 7 takes out the planting object W from the holding means 5, the conveying means 3 stops, and after the planting means 7 removes the planting object W, the next holding means 5 takes out by the planting means 7. If the conveying means 3 is driven intermittently so that the conveying means 3 moves to a position, the planting means 7 can take out the planting object W from the holding means 5 more satisfactorily. Accuracy is improved.
[0023]
The holder 5 will be described in detail. FIG. 4 is an enlarged perspective view of the holder, and FIG. 5 is an enlarged cross-sectional view of a state in which the planting object W is mounted on the holder. A substantially ring-shaped (C-shaped) base member 21 that is open, and a large number of elastically deformable napped bodies planted from the base member 21 toward the center side of the ring-shaped shape. A holding member 22 is provided. The base member 21 is attached to the conveying means (chain 3) via the attachment member 5a in a posture in which an axis substantially orthogonal to the center side of the ring shape is substantially orthogonal to the conveying direction of the conveying means (chain 3). In FIG. 4, the tip 7 a side of the planting body 7 passes from the top to the bottom through the gap G that is the open portion of the base member 21 formed on the front side.
[0024]
The planting object W held by the holder 5 moves the planting object W by lowering the holding portion of the planting object W in the holder 5 against the holding force by the holding member 22. Can be taken out from the holder 5 as it is.
[0025]
Further, the bulb planting device 1 includes a descending guide 25 along the descending portion of the chain 3, an object to be planted, as shown in front views of the guide member attached to the bulb planting device of FIGS. 2 and 6. Side guides 26 and 26 and a rear guide 27 are provided below the position where W is taken out. The descending guide 25 is disposed close to the outer peripheral side of the descending conveyance unit of the holder 5, thereby preventing the planting object W from jumping outward from the holder 5 in the falling posture.
[0026]
The side guides 26, 26 and the back guide 27 are provided along the descending locus of the tip 7 a of the implant 7, and the tip 7 a of the implant 7 takes out the planting object W from the holder 5 downward. When taking it to the surface S, the left and right sides and the back side of the planted object W are guided to move along the downward trajectory of the tip 7a of the planted body 7. Further, the side guides 26, 26 and the rear guide 27 are formed of an elastic material such as rubber, and are attached in a posture closer to the descending locus of the distal end portion 7a of the implant 7 toward the lower part of the guide, thereby further increasing the planting object W. The guide function is improved.
[0027]
The implanted body 7 is provided with a concave portion at its distal end portion 7a that serves as an engaging portion that engages with a part of the outer periphery of the planted object W. Since the tip 7a of the planted body 7 engages with the upper portion of the planted object W held by the holder 5 and is taken out downward and planted in the field, the planting object is taken from the time of removal from the holder 5 to the time of planting in the field. The posture change of the object W is difficult to occur.
[0028]
In addition, when planting the seed garlic W having a triangular pyramid shape, since the apex a having the triangular pyramid shape becomes a budding portion, the seed garlic W is planted on the field with the apex a facing upward. Therefore, when the seed garlic W is loaded into the holder 5 at the upper part of the chain 3, as shown in FIGS. When the seed garlic W loaded and held in the holder 5 is conveyed downward by the drive rotation of the chain 3, the top part “a” is at the top, as shown in FIGS. In this posture, the planted body 7 engages from above the seed garlic W, pushes it downward, takes it out, takes it to the field as it is, and implants it in the soil. Here, when the tip 7a of the implant 7 forms a conical recess 7b so that the upper part of the seed garlic W with the top a facing up as shown in FIG. The disorder of the holding posture of the seed garlic W due to 7 is less likely to occur, and the seed garlic W can be planted in an appropriate posture. Further, it is formed into a three-pronged shape composed of the three-piece pieces 7c... Of FIG. 7 (b), and the cross-sectional view taken along line AA is shown in FIG. If it forms so that it may match, rotation around an up-and-down axis is also suppressed and seed garlic W is planted in a still more appropriate posture.
[0029]
In the bulb planting apparatus 1 configured as described above, each holder 5 is horizontally transported between the two sprockets 11 and 11 at the upper position by the revolving operation of the chain 3, and each holder 5 is moved at the lower position. It turns into a reverse rotation posture and is horizontally transferred along the guide plate 12. Therefore, the planting object W can be held in each holder 5 by sequentially supplying and mounting the planting object W to the holding means 5 at the upper position, and the planting object W is in the lower position while maintaining its posture. The planted body 7 is moved to the planting posture, and the planted body 7 operates in time with the movement of the holder 5 due to the drive rotation of the chain 3 as appropriate, and the planted object W is pushed out from the holder 5 in that posture and lowered. By doing so, the planting object W is pushed into the soil of the field in a fixed posture and can be planted.
[0030]
The bulb planting apparatus 1 having the above-described configuration is, for example, mounted on a self-propelled machine 31 as shown in FIG. 8 as a side view of the bulb planter and as shown in FIG. Can be configured as a machine. The self-propelled aircraft 31 is provided with front wheels 32, 32 and rear wheels 33, 33 that can adjust the vehicle height, and a steering handle 31a that extends rearward. The bulb planting devices 1 and 1 and the loading platform 34 are provided at the rear of the aircraft. The bulb planting devices 1 and 1 are driven and rotated at a set ratio with respect to the traveling speed. In the illustrated example, the bulb planting devices 1 and 1 are arranged on the left and right sides to form a two-row planting. Further, on the rear side of the bulb planting devices 1, 1, pressure-reducing wheels 35, 35 are arranged to cover the upper part of the bulbs planted in the soil. The height of the airframe is set so that the height H from the farm scene S to the lower end of the holder 5 at the lower position of the bulbous planting device 1 is smaller than the height dimension of the planting object W.
[0031]
When planting bulbs, the planted object W is loaded on the loading table 34 and the vehicle height of the self-propelled aircraft 31 is set to the height H to travel. While the operator follows the left and right sides of the steering handle 31a, the planting object W is taken out from the loading table 34 and loaded in the upside down posture on each holder 5 to which the upper position of the bulbous planting device 1 is transferred. Thus, the planting object W loaded in each holder 5 is planted in the soil of the farm field in an appropriate posture by the planting body 7. Therefore, the bulbous planting device 1 having the above-described configuration allows the planting object W to be placed in a predetermined posture by a simple supply operation in which the planting object W is sequentially attached to the holding means 5 in the field without requiring any special preparation process. Can be planted sequentially in the field.
