The mechanism for pushing out at a constant time interval can be easily realized simply by providing one or more radial push bars on the rotating shaft. After the lowermost sugarcane seedling is pushed out, the upper seedling millet falls, becomes the lowermost sugarcane seedling, and is pushed out again, so that it is pushed out at regular intervals.

Claim 2 is a sugarcane seedling plant that runs a seedling planting machine in a field and drops sugarcane seedlings cut into a predetermined length one by one to a planting position in the field at a predetermined interval,
It is elongated in the running direction, and it has a structure that pushes the rear end of the lowest seedling mill forward from the back of the guide groove that puts seedling millet horizontally from the top opening and pushes it forward of the guide groove ,
Moreover, the sugarcane seedling planting machine is characterized in that a bottom portion of the guide groove is inclined forward and a plurality of the guide grooves are provided at a predetermined pitch.
In this way, the structure is elongated in the running direction, pushes the rear end of the lowest seedling mill forward from the back of the guide groove where a plurality of seedlings are put in from the opening at the upper end, and pushes it forward of the guide groove In addition, the bottom portion of the guide groove is inclined forwardly downward, and the force that the seedling mill slides forward acts, so that the force for pushing the seedling mill from the rear can be reduced. Further, since a plurality of the guide grooves are provided at a predetermined pitch, a larger amount of seedlings can be planted and work can be performed efficiently.

In this way, the lower end of the front wall of the guide groove has an opening through which only one seedling millet at the lower end can pass. Only one of the two is extruded, and no more than two are extruded. Moreover, since the opening for escape which can pass the push bar which passes the bottom slit of a guide groove is opened in the rear wall of a guide groove, each said radial push bar can carry out a rotational motion smoothly.

According to a fifth aspect of the present invention, a stock box is provided on a groove unit provided with a plurality of the guide grooves, and seedling mills in the stock box are supplemented to the guide grooves. The sugar cane seedling planting machine according to any one of claims 2 to 4.
In this way, since the stock box is provided on the groove unit provided with a plurality of the guide grooves, and the seedling mills in the stock box are replenished to the respective guide grooves, If a large amount of seedling milling is previously introduced, the seedling milling operation is smoothly performed since the seedling milling is automatically lowered and stored in each guide groove due to vibration during the running of the apparatus.

As in claim 1, the rear end of the lowermost seedling mill is pushed forward from the back of the guide groove that is elongated in the running direction, and a plurality of seedlings are horizontally stacked from the opening at the upper end. since a method of extruding a, by providing even mechanism pushing the rear end of the sugar cane seedlings, it is possible to extrude at regular time intervals. The mechanism for pushing out at a constant time interval can be easily realized simply by providing one or more radial push bars on the rotating shaft. After the lowermost sugarcane seedling is pushed out, the upper seedling millet falls, becomes the lowermost sugarcane seedling, and is pushed out again, so that it is pushed out at regular intervals.

As in claim 2, the front end of the guide groove is pushed forward from the back of the guide groove that is elongated in the running direction and is inserted into a plurality of seedling millet from the opening at the upper end and stacked horizontally. In addition, the bottom of the guide groove is inclined forward and the seedling mill slides forward, so the force to push the seedling from the rear can be reduced. Further, since a plurality of the guide grooves are provided at a predetermined pitch, a larger amount of seedlings can be planted and work can be performed efficiently.

According to a third aspect of the present invention, radial push bars are provided at the same pitch as the guide grooves on the rotary shaft disposed below the guide grooves in a direction perpendicular to the guide grooves, and Since the bars are shifted in the circumferential direction at every predetermined angle, the seedling mills in the plurality of guide grooves can be sequentially pushed out at regular time intervals by continuously rotating the radial push bar. Moreover, since the slit which the said each push bar can rotate pass is opened in the bottom of each said guide groove, it becomes possible to rotate each push bar continuously and to extrude seedling milling reliably.

As in claim 4, since an outlet through which only one seedling millet at the lower end can pass is formed in the lower part of the front wall of the guide groove, even if it receives a load of seedling milling stacked on the upper side Only one of the lowermost ends will be pushed out, and two or more will not be pushed out. Moreover, since the opening for escape which can pass the push bar which passes the bottom slit of a guide groove is opened in the rear wall of a guide groove, each said radial push bar can carry out a rotational motion smoothly.

Since the stock box is provided on the groove unit provided with a plurality of the guide grooves, and the seedling mill in the stock box is replenished to each of the guide grooves, the stock box If a large amount of seedling millet is put in the container in advance, it will be automatically lowered and stored in each guide groove due to vibration during the running of the device, etc. Is called.

Next, an embodiment of how the sugarcane seedling planting machine according to the present invention is actually realized will be described. FIG. 1 is a plan view of an embodiment of a sugarcane seedling planting machine according to the present invention, FIG. 2 is a sectional view taken along line AA, and FIG. 3 is a sectional view taken along line BB. 4 is a front perspective view in the direction of arrow a4 in FIG. 1, and FIG. 5 is a rear perspective view in the direction of arrow a5 in FIG.

In the illustrated example, for example, ten guide grooves 1 are formed at a constant pitch p with the partition wall 2 interposed therebetween, and two or more seedling mills 3 are stacked horizontally in each guide groove 1. be able to. Since the bottom plates 2a and 2a extend from the lower ends of the partition walls 2 to the guide grooves 1 ..., the seedling mills 3 in the guide grooves 1 ... are held by the bottom plates 2a and 2a. A slit S through which each push bar described later passes is opened between the bottom plates 2a and 2a.

As shown in FIG. 1 and FIG. 3, the length in the front-rear direction of each guide groove 1 is such that one seedling millet 3 enters, so that the upper seedling mill can descend smoothly, It is preferable that a slight gap is generated between the front end of the seedling mill and the front wall 4 of the guide groove and between the rear end of the seedling mill and the rear wall 5 of the guide groove.

The seedling mill 3 in each guide groove 1 has a structure in which only one of the lowermost ends of the radial push bar as shown in FIG. 3 is pushed out from the rear in the direction of the arrow. As shown in FIGS. 1 and 2, the push bar 6 in the radial direction is arranged at the same pitch as the guide groove 1 on the rotating shaft a disposed below the guide grooves 1 in a direction orthogonal to the guide grooves 1. A plurality of them are arranged. These push bars 6... Appear to be radial when viewed from the side as shown in FIG. 3, but as shown in FIGS. 1 and 2, each push bar 6... Is at every predetermined angle (in the illustrated example, every 45 degrees). It is shifted in the circumferential direction. Therefore, the seedling mill 3 in the next guide groove 1 is pushed out after 45 degrees behind the pushing operation of the seedling mill 3 in a certain guide groove 1. Thus, if the seedling mill 3 in the guide groove 1 at the final end is pushed out, it returns to the beginning 45 degrees later, and the seedling millet 3 in the first guide groove 1 is pushed out.

Since the seedling millet 3 is sequentially pushed out from the guide grooves 1 at different positions in this way, the fall position of the extruded seedling millet 3 is different, so that the figure is shown below each outlet 7 of the groove unit U. A hopper-shaped guide rod G as shown in FIG. 5 is provided, and all fallen seedling millet is guided in one place before falling into the planting groove of the field. Therefore, if the guide means is provided behind the tractor towed by the tractor, the seedling millet 3 can be dropped and planted immediately after digging the groove, and automation is put to practical use.

As shown in FIGS. 3 to 5, the bottoms 2 a and 2 a with slits of the guide grooves 1 are inclined forward and downward, so that the seedling mill 3 in the guide grooves 1. As a result, a force to slide down forward is generated, so that the force pushing the rear end of the seedling millet 3 can be reduced. Also, as shown in FIGS. 3 and 4, the lower end of the front wall 4 is cut to form an outlet 7 that is large enough to allow only one seedling millet at the lower end to pass through. Only one is extruded. On the other hand, as shown in FIGS. 3 and 5, the opening 8 for escaping is opened by cutting the lower end of the rear wall 5, so that the bottom slit S of each guide groove is pushed by the push bar 6 as shown in FIG. Does not get in the way when passing through.

In each guide groove 1 between the partition walls 2 ..., it is necessary to lay a plurality of seedling millets 3 in advance, but it is troublesome to insert the seedling millet 3 in each guide groove 1. Therefore, the stock box B is provided on the unit U of the guide grooves 1. As shown in FIG. 2 and FIG. 3, if a large amount of seedling millet is put into the stock box B in advance in a horizontally stacked state, the seedling millet in the stock box B will be guided to each guide groove by vibration during the running of the device. It is guided to 1 ... and is replenished. As shown in FIGS. 3 to 5, the upper end of each partition wall 2... Is formed in a convex arc shape, so that the seedling mill 3 in the stock box B is not caught on the partition wall 2 and is smoothly and reliably guided groove 1. It falls and is guided inside. That is, when the seedling millet 3 in the stock box hits the convex arcuate top end, the seedling millet on the convex arcuate top end becomes unstable, so that either one of the guide grooves 1. Will fall reliably.

Various embodiments are possible for the grooved bottoms of the guide grooves 1. In FIG. 6A, a flat plate is fixed to the bottom of the unit of the guide grooves 1... And a slit S is formed at the bottom of each guide groove 1. Therefore, the bottom plate 9 is integrated with the lower end of each partition wall 2 in an inverted T shape. In FIG. 6 (2), for example, a semi-cylinder 10 formed by dividing a vinyl chloride cylinder into two parts is integrated with the lower end of each partition wall 2 in an inverted manner. In FIG. 6 (3), for example, a circular arc plate 11 formed by dividing a cylinder made of polyvinyl chloride into four is attached and fixed back to back at the lower end of each partition wall 2. In this case, the shape is the same as the bottom plates 2a and 2a of FIGS. 6 (4) shows a slit between adjacent inverted V-shaped bottom plates V and V by, for example, mounting a V-groove shaped iron plate V bent at 90 degrees upside down and fixing it in a mountain shape at the lower end of each partition wall 2. The structure is such that S is formed.

The drive of the rotary shaft a for rotating each push bar 6 ... is connected to the tractor engine and other output units and the wheels of the cultivator via the pulley P and the V belt in FIGS. be able to. Of course, you may equip a single drive device only for the drive of the rotating shaft a.

The illustrated embodiment comprises a unit U having a number of guide grooves 1. However, a simple type with a single guide groove 1 is also possible. In this way, when the guide groove 1 is single, it is only necessary to radially arrange the push bars 6 in the radial direction on the same circumference of the rotation axis a, for example, at intervals of 90 degrees. The fall time interval of the seedling millet 3 due to the rotation of the push bar 6 as described above and the distance interval of the seedling millet 3 on the field groove are the angular interval of the push bar 6 ..., the rotational speed of the drive shaft a, and the travel of the device. Needless to say, it depends on the correlation such as speed.

As described above, according to the present invention, sugarcane seedlings cut into a predetermined length are stored in a guide groove larger than the outer diameter of the sugarcane in a state where they are laid in two or more stages, and from the back of the guide groove Since it has a structure that pushes the rear end of the lowest sugarcane seedling and pushes it forward in front of the guide groove, it can drop the sugarcane seedling one by one to the planting position in the field at a predetermined interval while traveling, By simple mechanical operation, millet can be automatically dropped one by one at regular intervals, and millet can be planted, which can be automated with an inexpensive device.
