  An embodiment according to the present invention will be described with reference to the drawings.

  FIG. 1 shows a bulb planting machine 1 and a bulb transporter 2 for net cultivation. The bulb planting machine 1 continuously plantes bulbs k such as tulips fed out from the receiving hopper 3 at the same time as laying the net on the cocoon u surface of the upright field by reciprocating adjacent work (symbol p in FIG. 1). . On the other hand, the bulb transporter 2 is configured to load the containers 5 and 5 filled with the bulb k on the rear portion of the tractor body 4, and when the bulb planter 1 travels in the direction of the arrow m along the ridge u of the field, The bulb transporter 2 that waits on the road s while waiting for the remaining amount of the hopper 3 approaches the bulb planter 1 while traveling backward in the direction of arrow n. When the new bulb k is moved to the receiving hopper 2, the bulb transporter 2 moves in the direction of the arrow n 'and waits again on the road s. The bulb transporter 2 includes two containers filled with refilling bulbs and can be transported from the road s toward the bulb planter 1 in the field.

  The details of the bulb planting machine 1 will be described with reference to FIG. 2. The planting machine 1 is configured to be attached to the rear portion of a tractor such as a tractor (not shown). Spirals 7 and 7 for guiding soil surface soil to the left and right from the front side, planting sponge roller 8 with a thin sponge pasted on the surface, covering soil disks 9 and 9, and ridge forming plate 10 for forming the covering soil into a kamaboko shape, Gauge wheels 11 and 11 are provided for maintaining the posture of the saddle forming plate 10. Further, a first net roller 13 for feeding the lower surface net 12 and a second net roller 15 for feeding the upper surface net 14 are mounted before and after the planting machine body 6, and the receiving hopper is placed on the front upper part of the planting machine body 6. 3 is provided. The receiving hopper 3 is provided with a bulb feeding portion 16 at a lower portion thereof, and is configured to be fed out by a predetermined amount.

  A container mounting frame 18 is provided at the rear of the receiving hopper 3 so as to be rotatable around a rotation fulcrum 17. The container mounting frame 18 is in the form of a roller conveyor having a plurality of rollers 19, and is configured to rotate around the rotation fulcrum 17 by the elevating cylinder mechanism 20. The front and rear length of the container mounting frame 18 is longer than the front and rear length of the container so that the container can be easily taken over from the rear.

  The left and right spiral bodies 7, 7, the sponge roller 8, the first and second net rollers 13, 15 are each configured to be driven to a predetermined rotation via a transmission mechanism (not shown). The soil covering disks 9, 9 are configured to be driven by a dedicated hydraulic motor (not shown). A frame denoted by reference numeral 21 is a frame attached to the tractor.

  Regarding the operation of the bulb planter 1, when the bulb planter 1 is pulled and advanced, first, the soil is guided to the left and right while cutting the topsoil of the farm scene by the spiral bodies 7 and 7 on the front side in the traveling direction (FIG. 3 ( B) Next, the lower surface net 12 fed out from the first net roller 13 and the upper surface net 14 fed out from the second net roller 15 are overlapped and laid in the field, but the guide rollers 22, 22. And 23 are provided to guide the upper and lower surface nets 12, 14. The lower surface net 12 that is fed out receives the bulbs k that are sequentially fed from the feeding portion 16 of the receiving hopper 3, and guides and transfers them. When the net 14 is superposed, the bulb k is held in a sandwiched state. In this state, the superposed net portions of the upper and lower nets 12 and 14 are wound around the sponge roller 8 in a predetermined manner. Receiving is laid in ridge surface, at the same time the bulbs k is evenly placed dispersed in ridge surface (FIG. (B)).

  Then, the soil removed on both the left and right sides by the rear soil covering disks 11 and 11 is moved toward the center and covered with the upper and lower surface nets 12 and 14 and the bulb k, and then the cocoon u is formed by the subsequent cocoon forming plate 10. (Figure (c)).

  It should be noted that the container mounting frame 18 is carrying a container during planting work, and since the pressure oil is gradually supplied to the elevating cylinder mechanism 20, the container is gradually inclined and the content bulb k is also increased. It is gradually fed out to the receiving hopper 3.

  By the way, when the bulbs of the hopper 5 of the bulb planter 1 run out or reach a small amount, the bulb carrier 2 waiting on the road is brought close to the bulb planter 1, and the bulb carrier 2 uses the container. The transported bulb k is replenished to the receiving hopper 3.

  The bulb transporter 2 is provided with a lift 24 via a three-point link mechanism 50 including a top link 50a and a lower link 50b at the rear part of a body 4 of a semi-crawler tractor as a towing vehicle body. 24a is configured to be tiltable to adjust the degree of inclination by extending and contracting the top link 50a from the substantially vertical posture when the top link 50a is shortened to the rear link when the top link 50a is extended.

  Further, the lift 24 is configured with a replacement mechanism A that can replace the front and rear positions of the two containers 5a and 5b. As a result, the container 5a placed on the container mounting frame 18 of the receiving hopper 3 of the bulb planter 1 is emptied at the front side of the replacement mechanism A, and the container 5b filled with the bulb k on the transporter 2 body side is received. The planting operation by the bulb planter 1 can be continued by replacing the container 5b filled with the bulb k to the container mounting frame 18.

  Note that the empty container 5a is close to the part immediately after the semi-crawler tractor of the bulb transporter 2 and waits for transport work.

  As described above, since the operation of collecting the empty container 5a and the bulb-filling container 5b are replaced, it is possible to replace the empty container 5a with a semi-crawler tractor as a transport vehicle after the empty container 5a is once placed on the field scene. Work is unnecessary.

  The replacement mechanism A has the following configuration.

  In other words, the lifting lift 24 constitutes a pair of left and right fork bodies 25, 25 that can move up and down with respect to the vertical frame 24a. That is, a pair of left and right vertical frames 24a and 24a are fixed to a base member 24b connected to the three-point link 50, and the vertical frames 24a and 24a are used as rails and slide vertically in the longitudinal direction with respect to the vertical frames 24a and 24a. Slide frames 24c and 24c are provided as possible, and the fork bodies 25 and 25 are fixed integrally with the slide frames 24c and 24c.

  A lateral support shaft 26 is provided in a non-rotating state so as to connect the left and right of the fork bodies 25, 25. A pair of left and right long replacement frames 27 and 27 are provided at the inner positions of the left and right fork bodies 25 and 25 so as to be rotatable around the lateral support shaft 26. The replacement frames 27 and 27 are configured such that an intermediate portion is rotatably supported by the lateral support shaft 26 and the front and rear end sides are connected by horizontal shafts 28 and 28 that are relatively rotatable to the left and right. The front and rear horizontal shafts 28 and 28 that are rotatably supported by the replacement frames 27 and 27 are provided with container receivers 29 and 29 for receiving the containers 5a and 5b, respectively. For example, a polygonal cylinder-shaped boss is formed on the container cradle 29 side, and the horizontal axis 28 side is formed on the polygonal axis so as to be fitted with the horizontal axes 28 and 28, respectively.

  Then, two sprockets 30 and 31 are integrally provided on one side end of the horizontal support shaft 26 in the intermediate portion (for example, a combination of a polygonal shaft and a polygonal shaft hole), and the front and rear horizontal shafts are provided. A sprocket 33 interlocked by the sprocket 30 and the chain 32 and a sprocket 35 interlocked by the sprocket 31 and the chain 34 are provided at one end of the 28, 28. The sprockets 33 and 35 are assembled to the horizontal shafts 28 and 28 so as to be integrated, for example, in a relation of a polygonal axis and a polygonal axis hole.

  On the other end side of the horizontal support shaft 26 at the intermediate portion, a sprocket 37 is provided integrally with the horizontal support shaft 26, and between the sprocket 38 supported by a support shaft 38 ′ provided on one side of the fork body 25. Chain 39 is passed over. Further, the tip end of the piston of the hydraulic cylinder mechanism 40 for container replacement is pivotally connected to the chain link portion of the chain 39. The base end side of the hydraulic cylinder mechanism 40 is connected to the vertical frame 24a.

  When the hydraulic cylinder mechanism 40 is expanded and contracted, the piston portion forcibly pushes and pulls the chain 39, and the reciprocating motion rotates the lateral support shaft 26 in the forward and reverse directions via the chain 39 and the sprocket 37. With the forward / reverse rotation of the lateral support shaft 26, the replacement frames 27, 27 rotate, and the front and rear positions can be changed while maintaining the posture of the container receiving bases 29, 29. That is, when the replacement frames 27, 27 are rotated forward (in the drawing, clockwise), the container receiving base 29 and the container 5b on the side close to the vertical frame 24a rotate downward, and the container receiving base 29 and the container 5a on the far side are rotated. Will be rotated upward and replaced. At this time, the sprockets 30 and 31 of the lateral support shaft 26 are in a fixed state and are not allowed to rotate. On the other hand, the sprocket 33 and the sprocket 35 that mesh with the chains 32 and 34 by the forward rotation of the replacement frames 27 and 27 gradually move leftward. Rotate to. For this reason, the container cradle 29, 29 is maintained in a substantially horizontal posture and the front and rear are switched.

  That is, the horizontal support shaft 26 that supports the intermediate portion side of the replacement frames 27, 27 on the lift lift 24 side, the sprockets 30, 31 provided integrally with the horizontal support shaft 26, and the front and rear ends of the replacement frames 27, 27 The horizontal shafts 28 and 28 provided integrally with the container pedestals 29 and 29, the sprockets 33 and 35 provided integrally with the horizontal shafts 28 and 28, and the sprocket 30 of the horizontal support shaft 26, respectively. A posture maintaining mechanism B is configured by chains 32 and 34 that span between 31 and the front and rear horizontal shafts 28 and 28.

  Further, during the replacement operation of the containers 5a and 5b, the height of the fork bodies 25 and 25 is adjusted along the vertical frame 24a of the lift 24 so that the container receiving base 29 that rotates downward does not contact the ground. Keep it.

  In addition, the container frames 29 and 29 can be reversed and replaced by providing the replacement frames 27 and 27 not only in the normal direction but also in a manner capable of interlocking with the reverse direction. That is, when the replacement frames 27 and 27 are rotated in the reverse direction (left rotation in the figure), the container receiving base 29 and the container 5b on the side close to the vertical frame 23a are rotated upward and far from each other, unlike the operation during the forward rotation. The container holder 29 and the container 5a on the side can be rotated downward to be exchanged. Thus, normal rotation / reverse rotation can be selected, and in which direction the rotation is to be performed may be arbitrarily selected in view of whether the containers 5a and 5b are empty or the surrounding conditions.

  In the present embodiment, the structure is such that the piston tip of the container replacement hydraulic cylinder mechanism 40 is pivotally connected to the chain link portion of the chain 39 and the replacement frames 27 and 27 are rotated. Instead of a connection configuration with a chain link, a reciprocating mechanism such as a link mechanism that swings and swings a bucket portion of a loader bucket for a construction machine may be configured.

  In this way, by configuring the replacement mechanism A and the posture maintaining mechanism B, the front and rear containers 5a and 5b can maintain their postures without being inverted up and down and can change the front and rear positions.

  Further, the lift 24 connected to the machine body side by the three-point link mechanism 50 is provided so that the forks 25 and 25 can be lifted and lowered by the configuration of the slide frame 24 a, and the lift 25 is the top link of the three-point link mechanism 50. Since the tilt structure is formed by expansion and contraction of 50a and the replacement mechanism A such as the replacement frames 27 and 27 is configured on the lift 24, the container holders 29 and 29 are tilted forward from a horizontal position at an appropriate height. Since the containers 5a and 5b can be easily moved, the front and rear containers 5a and 5b can be replaced, and the containers 5a and 5b such as container receiving frames of the containers 5a and 5b need to be placed on the ground. In addition, the transfer work of the containers 5a and 5b is facilitated.

  7 and 8, the takeover operation of the containers 5a and 5b will be described. The container pedestals 29 and 29 on the bulb transporter 2 side form a pair of fork-like mounting surfaces at appropriate intervals on the left and right sides. On the other hand, the container mounting frame 18 on the bulb planter 2 side has a plurality of rollers 19, 19. And the fork-like mounting surface of the container pedestal 29 on the bulb transporter 2 side has two parallel notch forming portions formed by the fork-like mounting surface of the container mounting frame 18 on the bulb transplanter 1 side in the vertical direction. It is provided so that it can pass through. Therefore, the container carrier 18 has an empty container 5a by retreating the bulb carrier 2 and adjusting the lifting lift 23, and the empty container 5a is first collected. In this case, the bulb carrier 2 is recovered. Is moved closer to the bulb planter 1 (FIG. 1), and the empty container 5a is transferred to the container cradle 29 by sliding the rollers 19 and 19 of the container mounting frame 18 on the rear container cradle 29 (FIG. 7). ).

  Then, the replacement mechanism A is operated to replace the bulb filling container 5b of the container cradle 29 close to the fuselage side with the rear side and the empty container 5a with the front side.

  Thereafter, the container 5b is transferred to the container mounting frame 18 as follows. That is, the container pedestal 29 is close to the container mounting frame 18 of the stopped bulb transplanter 1, and the container pedestal 29 is tilted backward by adjusting the height with the lifting lift 24 (FIG. 8). (I)). Next, the container 5b is slid and moved by the inclination of the container cradle 29 and the rollers 19 and 19 of the container mounting frame 18 (FIG. 2B). By actuating the cylinder mechanism 23, the container 5a of the container cradle 29 becomes inclined while moving to the container mounting frame 22 side, and the bulb k in the container 5a is eventually put into the receiving hopper 3. In the meantime, the bulb transporter 2 is moved forward at a slow speed and separated from the bulb planter 1 ((c) in the figure).

  As the operation resumes, the inclination angle by the cylinder mechanism 23 is gradually increased, and the bulb k in the container 5 b is appropriately put into the receiving hopper 3. In addition, damage to the bulb k can be prevented by gradually introducing it.

  In addition, since the bulb transporter 2 can move to the road s side, the empty containers 5a and 5b can be easily loaded from a truck transport vehicle (not shown) waiting on the road s.

  In the above embodiment, an example in which the empty container 5a and the bulb filling container 5b are replaced has been described. However, the container 5a and 5b are both bulb filling containers, and a large capacity receiving hopper 3 is provided, so that the first container 5 May be immediately put into the receiving hopper 3 and the second container 5 may be held on the container mounting frame 19 and gradually fed as necessary. In this case, after the first container is loaded, the container is returned to the container cradle 29, and then the switching mechanism A switches the front and back to perform the second cup.
