Description

The present invention relates to a continuous planting device having a structure in which sugarcane for seeds, which has been previously cut to 25 to 35 cm, is continuously dropped into a planting groove.

According to the description in the patent document, a plow blade portion is provided in front of the seed guide means for dropping the seed millet, and a planting machine provided with a pressing ring on the rear side is pulled by a tractor or the like to manually guide the seed millet. A device is disclosed in which seed millet is dropped and planted in a groove formed in a field by a plow blade portion by inserting it into a means.
However, in large-scale farmers, the work of manually supplying seed millet at regular intervals is a heavy burden, and from the viewpoint that automation is necessary, a seed guide means is provided outside the side wall of the large seed millet hopper, and the seed guide means is provided. Grizzly Manufacturing in 2002 was an automatic planting device that used escalator means to climb seed millet in the hopper and dropped it into the outer seed guide means to drop it into a field ditch formed by a plow blade. It is presented in the catalog (non-patent document) of Pty. Ltd.

However, in the structure described in Non-Patent Document 1, as shown in FIG. 1, when the gutter d of the escalator-shaped conveyor C climbs a slope, the seed millet A2 other than the seed millet A1 for planting in the gutter d , When climbing a slope with A3 on it, passing through the top and turning over, extra seed millet A2 and A3 other than the planted seed millet A1 in the gutter d also fall into the seed guide means all at once. It ends up.
Seed millet for planting needs to be dropped into the planting ditch at an almost constant frequency and planted at approximately regular intervals, but if extra seed millet other than the original planted seed millet also falls, it will be constant. It becomes impossible to plant millet.

Further, in the conventional structure, as shown in FIG. 2, the seed millet in the hopper is as shown in A between the cover portion e surrounding the lower end portion of the conveyor C at the interval portion between the gutters d and d of the conveyor C. There was a problem of getting caught.
The technical subject of the present invention pays attention to such a problem, and climbs the seed millet from the hopper for storing the seed millet in an escalator manner, receives the seed millet, transfers it to the top with a gutter, and transfers it to the seed guide means on the outside of the hopper. We have realized a device that can solve the above-mentioned problems in the planting device with a structure that allows it to be dropped to the ground, receive only the seed millet necessary for planting, and transfer it uphill by gutter means, and also eliminate the clogging phenomenon of the seed millet at the lower end of the conveyor. To do.

The technical problem of the present invention is solved by the following means. The first aspect of the present invention is a device having a structure in which a conveyor climbs an escalator from the hopper for storing seed millet, receives the seed millet, transfers it to the top with a gutter, and drops it into the seed guide means outside the hopper.
As shown in FIG. 8, the bottom plate of the bending / stretching plate that also serves as the inner wall of the hopper can rotate up and down with the horizontal axis on the bottom side of the hopper as a fulcrum, and the bottom plate is pushed up by the push-up driving means or the compression spring means of the bottom plate to be bent in the middle. It is a sugarcane continuous planting device characterized in that when the vertical plate on the opposite side to the portion is extended, the structure is such that the vertical plate is inclined almost straight together with the bottom plate.
In this way, the bottom plate of the bending and stretching plate, which also serves as the inner wall of the hopper, can rotate up and down with the horizontal axis on the bottom side of the hopper as a fulcrum, and the bottom plate is pushed up by the push-up driving means or the compression spring means of the bottom plate to form a bent portion. On the other hand, when the vertical plate on the opposite side is extended, the structure is such that it is in a straight tilted state together with the bottom plate. It can be stretched straight with it.
Therefore, if the bottom plate is made horizontal, the volume inside the hopper will increase and a larger amount of seed millet can be stored. The seed millet slides down on the inclined bottom plate, slides down on the conveyor, and is transferred to the seed guide means side.

According to claim 2, as shown in FIG. 8, a movable plate for preventing seed millet in the hopper from falling into a gap in front of the start end of the outbound route near the start end of the outbound route of the conveyor is provided horizontally in the width direction of the conveyor. The sugar cane continuous planting device according to claim 1, wherein the sugar cane is hung on a shaft, and when a gutter arrives, the movable plate is pushed up and retracted by the gutter so that the cane can be moved into the hopper. ..
In this way, a movable plate that prevents seed millet in the hopper from falling into the gap in front of the starting end of the outward path is hung on the horizontal axis provided in the width direction of the conveyor near the starting end of the outward path of the conveyor. Therefore, when the receiving gutter arrives from the lower side of the starting end of the conveyor, the movable plate is pushed up and passed by the receiving gutter, so that the operation of the receiving gutter is not hindered, and the movable plate usually hangs down by its own weight to close the gap. Therefore, the problem that seed millet in the hopper gets into the gap and becomes clogged is solved.

According to claim 3, the conveyor is horizontal at the bottom of the hopper, then climbs an inclined inner wall as shown in FIG. 5, and is vertically on the top of the conveyor as shown in FIG. 1 or inside the hopper as shown in FIG. The sugarcane continuous planting apparatus according to claim 1 or 2, wherein the structure is such that the sugarcane rises in a warped state.
In this way, at the top of the conveyor, the structure is such that the conveyor rises in a warped state inside the hopper, so extra seed millet that overlaps on each gutter will fall into the hopper by its own weight. Only the seed millet in the gutter can climb to the top without falling even if the gutter tilts inward, and then moves to the outside of the hopper, and when the gutter moves downward, the seed guide means It falls from the inside into the planting ditch and is planted.
In addition, if the top of the conveyor rises vertically, the seed millet on the seed millet in the gutter will also climb the slope, and when it passes through the top and reverses, it will be included in the seed guide means. Since it will fall all at once, extra seed millet will also fall and be planted.

As in claim 1, the bottom plate of the bending / stretching plate that also serves as the inner wall of the hopper can rotate up and down with the horizontal axis on the bottom side of the hopper as a fulcrum, and the bottom plate is pushed up by the push-up driving means or the compression spring means of the bottom plate. When the vertical plate on the opposite side to the center-folded part is extended, it will be in a straight tilted state together with the bottom plate. It can be stretched straight.
Therefore, when the bottom plate is in a horizontal state, the volume inside the hopper increases and a larger amount of seed millet can be stored. The seed millet slides down on the conveyor, slides down on the conveyor, and is transferred to the seed guide means side.

As in claim 2, a movable plate that prevents seed millet in the hopper from falling into the gap in front of the start end of the outbound route is hung on a horizontal axis provided in the width direction of the conveyor near the start end of the outbound route of the conveyor. There is. Therefore, when the receiving gutter arrives from the lower side of the starting end of the conveyor, the movable plate is pushed up and passed by the receiving gutter, so that the operation of the receiving gutter is not hindered, and the movable plate usually hangs down by its own weight to close the gap. Therefore, the problem that seed millet in the hopper gets into the gap and becomes clogged is solved.

As in claim 3, at the top of the conveyor, the conveyor rises in a warped state inside the hopper, so extra seed millet that overlaps on each gutter falls into the hopper by its own weight. Therefore, only the seed millet in the gutter can climb to the top without falling even if the gutter tilts inside the hopper, and then moves to the outside of the hopper, and when the gutter moves downward, the seeds It falls from the guide means into the planting ditch and is planted.
In addition, if the top of the conveyor rises vertically, the seed millet on the seed millet in the gutter will also climb the slope, and when it passes through the top and reverses, it will be included in the seed guide means. Since it will fall all at once, extra seed millet will also fall and be planted.

It is a side view of the upper end part of the conveyor of the conventional continuous planting device of the uphill escalator type sugar cane. It is a side view which shows the clogging phenomenon at the beginning end part of the conventional escalator. It is a front view of the sugar cane continuous planting device. It is a left side view of the apparatus of FIG. It is a perspective view which shows the internal structure of a hopper. It is a side view of the upper end part of a conveyor. It is a perspective view which looked at the part of the vertical plate of FIG. 5 from the inside of a hopper. It is a side view which shows the bending and stretching operation part of a bottom plate.

Next, an embodiment will be described of how the sugarcane continuous planting apparatus according to the present invention is practically embodied. FIG. 3 is a front view of the sugarcane continuous planting device according to the present invention, in which a bowl-shaped hopper 2 is provided behind the plow blade 1, and the plow is towed by a tractor and travels on the left and right wheels W1 and W2. The planting operation is performed while digging a groove in the field with the blade 1. The seed millet in the hopper 2 is transferred by a gutter 3 that moves uphill on an escalator-shaped conveyor, falls into the guide duct G when descending over the top of the conveyor, and falls from the lower end of the guide duct G having a width D. , It falls into the planting groove dug by the plow blade 1 and is planted.

FIG. 4 is a left side view of the apparatus of FIG. 3, and the guide duct G has a dimension in which the length L in the traveling direction by the wheel W1 is about 2 to 3 times the length of the seed millet A. The guide duct G may have the same dimension L up to the lower end, but may be formed in an inverted trapezoidal shape as shown in the figure, and the lower end side may be gradually narrowed.
Since the horizontal receiving gutter 3 has a length that allows two or three seed millets to enter in series at the same time, the guide duct G contains two or three seed millets A at the same time and has a length L. They fall in a row in the area and fall into the planting groove together, but since they fall while traveling on the wheel W1, they are arranged and planted at substantially regular intervals in the groove.
When the seed millet A falls into the planting groove, it is covered with soil by the pressurizing roller 4 and pressurized. In addition, you may provide an upside-down C-shaped soil covering plate in front of the pressurizing roller 4, cover the dropped seed millet with soil, and then pressurize with the pressurizing roller 4.

FIG. 5 is a perspective view showing the internal structure of the hopper 2. A conveyor C traveling in a direction parallel to the axles of the wheels W2 and W1, that is, in a direction perpendicular to the traveling direction of the planting device, is a guide duct from the bottom of the hopper 2. It is arranged in an escalator shape up to the upper end of G.
Since this conveyor C is shaped so that its top side warps toward the inside of the hopper, each of the receiving gutters 3 ... horizontally supported on the outbound route of the conveyor has its opening oriented as the conveyor C progresses. It changes gradually.
That is, as the conveyor C travels from the bottom of the hopper to the upper end side of the guide duct G and moves uphill, each gutter 3 ... The extra seed millet A2 and A3 that had been there will naturally fall into the hopper.
The side wall of the hopper 2 is provided with a triangular concave chamber formed at a right angle between the bottom plate and the vertical plate 5 on the opposite side of the climbing portion of the conveyor C in order to increase the storage capacity.

FIG. 6 is a side view of the top of the conveyor C, in which the diameter of the upper end sprocket portion supporting the chain 6 constituting the conveyor C is α, whereas the distance β between the outward path and the return path of the chain 6 except for the sprocket portion. By forming the conveyor C so as to be narrow, the outward path toward the top of the conveyor C, that is, the climbing motion portion is curved inward in the hopper.
In the region where the chain 6 rises almost vertically in this way, each gutter 3 ... rises directly above, so that the gutter-shaped opening is upward, and extra seed millets A2 and A3 overlap on it. However, in the warped part near the upper end of the conveyor, the receiving gutter 3 tilts to the inside of the hopper, so the extra seed millet A2 and A3 overlapping on the upper side of the seed millet A1 in the receiving gutter 3 are inside the hopper. It falls naturally.
Therefore, when passing through the top of the hopper and shifting to the return route, the opening of the receiving gutter 3 faces the guide duct G side, so that only the seed millet A1 in the receiving gutter 3 falls into the guide duct G, and the opening thereof is directed to the guide duct G side. It falls from the lower end into the soil planting ditch and is planted.
The return path side, that is, the guide duct G side also has a shape in which the top of the conveyor C is warped outward, but the guide duct G side does not necessarily have to be warped.

FIG. 7 is a perspective view of the portion of the vertical plate 5 of FIG. 5 as viewed from the inside of the hopper. A right-angled triangular variable chamber is formed by the vertical plate 5 and the horizontal bottom plate 6, and seed cracks are also formed in the variable chamber. Since it can be stored, the storage capacity of the hopper increases. However, if the bottom plate 6 is always in a horizontal state, the seed millet on it cannot be moved onto the conveyor C. Therefore, when the number of stored seed millet in the hopper is low, the bottom plate 6 rises and tilts to be on the bottom plate 6. The structure is such that the seed millet can be slid onto the conveyor C. It should be noted that each gutter 3 ... is long enough to accommodate two or three seed millets A1 ... in series (same or shorter than the length L of the guide duct G).
FIG. 8 is a side view showing a bending / stretching operation portion of the bottom plate 6. The horizontal axis 7 that supports the front end of the bottom plate 6 near the center of the hopper rises from the return route because it supports the movable plate 8 in a hanging state while being located above the start end of the outward path of the conveyor C. Each of the receiving gutters 3 when shifting to the outward route moves into the hopper by pushing up the movable plate 8, scoops and stores the seed millet in the hopper, and then shifts to the climbing operation of FIG.

After the receiving gutter 3 rises and arrives from the conveyor return path and pushes up and passes through the movable plate 8, the movable plate 8 descends by its own weight to close the gap between the conveyor and the outward path surface, so that the seeds in the hopper There is no problem that the millet A gets into the gap and becomes clogged as shown in FIG. A stopper is provided so that the movable plate 8 is not pushed toward the conveyor folding portion side by the seed millet in the hopper.
The connecting portion 9 between the bottom plate 6 and the vertical plate 5 has a movable structure and is usually bent at a right angle like a solid line, but when the bottom plate 6 is pushed up by a driving means such as a hydraulic cylinder 10, the bottom plate 6 is pushed up. The connecting portion 9 of the bottom plate 6 and the vertical plate 5 extends straight and becomes a broken line state.

As a result, the seed millet stored on the bottom plate 6 slides down on the conveyor C when the bottom plate 6 extends in the broken line state, and is conveyed to the guide duct G side. When the seed millet in the hopper disappears and a new seed millet is stored next time, if the bottom plate 6 is lowered by the driving means 10 to make it horizontal as shown by the solid line, the vertical plate 5 stands in the vertical state. , Seed millet can be stored in the triangular concave variable chamber 11, and the storage capacity of the hopper can be increased. The upper end of the vertical plate 5 slides up and down while being supported by the inner surface of the hopper outer wall plate 12.

If the bottom plate 6 is constantly pushed up by a pressurizing means such as a compression coil spring instead of the drive means 10, when the seed millet is stored in the hopper, the bottom plate 6 is pushed down by the weight and becomes a solid line state. When the seed millet in the hopper is low, the load received by the bottom plate 6 decreases, so that the bottom plate 6 can be pushed up and tilted by the elasticity of the pressurizing means.
If the bottom plate 6 is slightly tilted, the seed millet on the upper side gradually slides down to the conveyor C side due to the vibration during running of the hopper, so that the load on the pressure means such as the drive means 10 and the compression coil spring is reduced, and the seeds are seeded. The millet slides down smoothly.
The variable chamber 11 composed of the vertical plate 5 and the bottom plate 6 that moves up and down may be provided not only on the opposite side of the conveyor uphill portion but also on the rear side or the front side in the hopper 2. In this case, the horizontal shaft 7 for supporting the bottom plate 6 does not need to serve as a hanging support for the movable plate 8, but is a support shaft dedicated to the bottom plate 6, and the horizontal shaft 7 for supporting the movable plate 8 in FIG. It becomes a right angle direction.

As described above, according to the present invention, the gutter that receives the seed millet and operates uphill tilts inward of the hopper before reaching the top of the conveyor, and the excess seed millet that overlaps falls into the hopper at all times. Seed millet can be arranged in the ditch of the field on average at a predetermined frequency, and the waste of seed millet is eliminated. In addition, the problem that seed millet is clogged in the hopper is solved, and the storage capacity of the hopper can be increased.
