Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for making vegetable and flower seedlings and a method for planting the seedlings.

[0002]

2. Description of the Related Art As a conventional seedling raising device, for example, as disclosed in Japanese Utility Model Publication No. 57-43621, a strip-shaped bottom plate 501 having water passage holes is vertically provided at a predetermined pitch. Seedling stand 5 formed by vertically arranging rectangular partition plates 503
00, a rectangular outer frame 510 with a large number of parallel partition walls 512.
A small wooden room 514 with a time signature provided by dividing it by
It is known that a potting space 520 surrounded by the partition wall and the partition plate is filled with soil to sow seeds and raise seedlings. (See Figure 10).

This seedling raising device takes out the seedling stand 500 from the outer frame 510 when the seedlings are planted, and separates the partition plate 50.
Remove the root pot held between 3 with fingers and plant it in a ridge, or put a feeding claw on the water hole at the bottom of the seedling stand and use a transplanter capable of pitch feeding, Push the bowl from the side,
It is used to remove it from the seedling stand and drop it into the planting device of the transplanter.

[0004] In general, seedlings grow along the pot surface when they grow in the soil and reach the pot surface surrounding the soil as the root grows. Therefore, when the seedlings reach a suitable time for planting, the soil is held and surrounded by a myriad of roots to form a root pot. However, since the amount of roots varies depending on the type of vegetables and flowers, the strength of the root pot depends on the variety and growth of the plant. On the other hand, in forming a root pot, the root presses the soil to the inner surface of the pot, and the root fills the gap between the soil and the inner surface of the pot. It gets higher as you go.

Furthermore, if there is a gap, the root will enter into it. Therefore, if there is a water passage hole on the lower surface like the above-mentioned seedling stand, the tip of the root will enter into this and depending on the conditions, The roots that have passed through the water holes further spread to the left and right, and in order to remove the seedlings from the seedling raising equipment, it is necessary to cut the roots protruding from the water holes and then apply a large force to the root pot to separate them.
In addition, since roots generally go downward, roots that strike the side of the pot tend to move downward along the face of the pot while concentrating on the corners of the pot and sticking to the pot surface. . By the way, in order to automatically detach it from the seedling stand on the transplanter using the conventional seedling raising equipment,
First, the root pot is pushed sideways from the side to remove it from the seedling stand, and then it is lowered into the planting device.

However, even when the protruding roots are cut off, the roots of the vegetables and flower seedlings that have reached a suitable time for planting still enter the water passage holes and firmly fix the root pot. When the seeds are separated from the seedling stand by mechanically pushing the root pot from the side due to the fact that the root and the soil are in close contact with the intersection of 501 and the partition wall 503, a large force is required for the detachment. However, the seedlings may be damaged, and the root pot itself may collapse, which may make planting difficult. Therefore, in this type of seedling stand, it is ideal to sandwich the root pot from both sides and lift it up to remove it, but if it is not done by hand, the mechanism will become complicated and the time required for removal will also increase. As a result, the planting speed becomes slow and the transplanter becomes large and expensive.

[0007]

It is an object of the present invention to provide a seedling raising device which can easily separate root pots with a small force at the time of planting, and a mechanical pot seedling capable of efficient planting work using this device. The purpose is to disclose a new planting method.

[0008]

A first aspect of the present invention is to provide a seedling box comprising a bottom plate of a box whose upper surface is open and a large number of water drainage holes, and a seedling box which are closely attached to each other and arranged in parallel. It is composed of a combination with a seedling frame that is stored in a state and defines a large number of nursery spaces in the seedling box, and the seedling frame has a partition wall provided on one side with a vertical plane that can traverse the inside of the seedling box. , On the opposite side of the partition wall,
A large number of pot defining walls are provided at a predetermined pitch along the extending direction of the partition wall, and project from the partition wall by a predetermined width in a direction substantially perpendicular to the longitudinal direction of the seedling frame. The seedling raising device is characterized in that

In the above-mentioned seedling raising device, when seedling raising is completed and the seedling frame is removed from the seedling box, the seedling frame is manually removed even if there is a root protruding from the drainage hole to the bottom of the box. Therefore, the ideal removal process can be easily performed without damaging the root, and the seedling frame taken out from the seedling box holds the rootpot of the seedling in a state of laterally sandwiching it. Therefore, the top surface, bottom surface and one side surface of the root pot are open, and the bonding force between the root pot and the seedling frame is such that the bottom surface of the root pot and the left and right side surfaces are in close contact with each other. Much smaller than if
The pressing force applied to the upper surface of the root pot allows it to be easily detached from the seedling frame.

A second aspect of the present invention is characterized in that, in the seedling raising apparatus defined in the above first aspect, the planar shape of the space sandwiched by the adjacent pot defining walls is substantially U-shaped. It is in the seedling raising equipment. In this case, since the shape of the pot does not have an acute-angled corner portion, concentration of the root on the corner portion can be prevented, and the root pot can be easily detached from the seedling frame. In order to further facilitate the detachment, the wall defining the wall may not be a vertical wall but may be a wall that inclines outward so that the volume of the root pot increases as it goes downward.

A third aspect of the present invention is to provide a partition wall having a vertical plane on one side, and a partition wall provided on the side opposite to the partition wall at a predetermined pitch along the extending direction of the partition wall, and , A seedling frame provided with a large number of pot-defining walls protruding from the partition wall in a direction substantially perpendicular to the extending direction of the partition wall by a predetermined width,
Prepare a large number of seedlings with root pots held between the walls of the pot,
Along the guide portion of the seedling frame, by moving the seedling frame, at the seedling drop opening that opens on the bottom surface of the guide portion, push the root pot downward to separate the seedling from the seedling frame and plant it. It is a characteristic seedling planting method.

The seedling frame holds the root pot of the seedling in a state of being pinched from the side with fingers, so that it can be pushed out with a relatively small downward pressure and removed from the seedling frame. The seedlings will not be damaged, and the fall speed will be very close to natural fall, so there will be no damage to the seedlings due to drop supply, and since separate supply will be performed in one operation, it will not affect the planting mechanism and ridges. The seedlings can be supplied promptly, and the posture of the seedlings in the planting hole is not disturbed.

A fourth gist of the present invention is to provide a partition wall having a vertical plane on one side, and a partition wall provided on the side opposite to the partition wall at a predetermined pitch along the extending direction of the partition wall, and , A root pot is held between the pot-defining walls of a seedling frame provided with a large number of pot-defining walls protruding from the divider wall in a direction substantially perpendicular to the extending direction of the divider wall by a predetermined width Prepared a large number of seedlings, provided on a self-propelled vehicle having a seedling planting mechanism, a guide portion of the seedling frame and a feed provided so as to project into the opening provided at the bottom of the guide portion. By means of a seedling planting machine provided with means and a seedling dropping means facing above the seedling drop opening opening in the guide portion, and engaging with feeding means such as a recess provided in the bottom surface of the seedling frame Part is supplied to the guide portion by engaging the feeding means, and at the seedling drop opening, the seedling dropping means applies seedlings to the seedling planting mechanism. In methods seedling planting, characterized in that the lower supply.

By such a method, seedlings that are moved continuously in parallel to the ridge direction and continuously supplied are dropped and supplied vertically to the seedling planting mechanism at the seedling drop opening. Since the shape of the ridge in the width direction can be narrowed,
Even with a multi-row planting machine, the planting machine can be downsized without taking the width.

A fifth aspect of the present invention is the seedling planting method defined in the fourth aspect, wherein the seedling dropping means is a rocking lever which is interlocked with the operation of the seedling planting mechanism, and the rocking lever. Has a seedling dropping rod rotatably supported at a fixed angle in a state of being orthogonal to the lever at the tip of the seedling, and one end of the seedling dropping rod biased by a spring member to the upper limit position of turning is a seedling dropping rod. Located above the mouth, the other end of the seedling dropping rod is located above the elastic member, and the lower end of the swing lever moves the other end of the seedling dropping rod downward while pressing the elastic member. At this point, one end of the seedling dropping bar is moved at a speed faster than the descending operation of the swing lever to drop the seedlings.

The above-mentioned scraping rod, when applying a downward force to the root pot, snaps the instantaneous force for overcoming the initial resistance force due to the separation of the root pot and the seedling frame,
Since it affects the root pot, the root pot is not damaged and the root pot can be separated quickly and reliably. less than,
Examples will be given.

Reference numeral 15 denotes a fitting groove running in the partition wall 12 in the longitudinal direction. When the seedling frame 10 is stored in the box body 1, the tip 14a of the pot defining wall is fitted into the fitting groove so that adjacent seedling frames can be connected to each other. The gap is prevented, and the degree of sealing of the side surface of the seedling space 20 is increased. The upper surface of the seedling frame 10 is composed of a smooth surface, but the rear surface 13 of the seedling frame has the same pitch interval as that in which the pot defining walls are provided, as shown in FIG. A blind hole 16 is provided as an engaging portion with which a feed pawl as a feeding means of the machine should be engaged.

As shown in FIG. 1, the apparatus for raising seedlings according to the present invention, which is composed of such a combination of the seedling frame 10 and the box body 2, has the first seedling frame on the rising edge 4a on one side and the pot forming wall thereof. Set with the tip abutting, then set the next seedling frame by fitting it into the fitting groove of the first seedling frame.

There is. The drive sprocket 66 is interlocked with the operation of the crankshaft 37 via the deceleration sprockets 68, 69, 70, and one cycle operation of the crankshaft 37 causes the feed pawl 64 to move one pitch in the direction of the arrow X. Moving.

The seedling drop openings 71, 71, ... Are opened near the rear wheel 34 side end of the guide troughs 61 ,. When the crankshaft 37 is near the bottom dead center, the hopper 41 of the seedling planting portion is located immediately below the seedling drop opening 71. A bag-shaped seedling frame receiver 72 having an open upper surface is attached to an end of the guide gutter 61 on the rear wheel side. An empty seedling frame that has passed through the seedling dropping port is pushed by the succeeding seedling frame into the seedling dropping hole and stored. The seedling drop opening 71 is provided with seedling drop means. Explaining the configuration of this seedling dropping means, in FIG. 8, first, a swinging lever 75 is pivotally supported by a supporting piece 74 standing on a work table near the seedling dropping port 71, and one end of the swinging lever 75 is supported.

[0032]

The planting machine having the above structure is placed, for example, over a ridge in a greenhouse, and the seedling frame 10 is taken out from the seedling box 2 placed at the tip of the workbench 60, and the blind hole 16 on the rear surface thereof is removed. The feed claw 64 protruding from the opening of the guide groove 61 is fitted, and the tip of the seedling frame is set in the guide groove so that the tip of the seedling frame is the seedling drop opening only at the beginning. When the motor M is turned on, the crankshaft 37 descends, the planting part rises, and the push-up piece 40e protruding from the planting part 40 to the rear of the vehicle also rises. In the rising area of this push-up piece,
The lower end of the operating rod 82 for driving the seedling dropping means is located, and when the planting part 40 approaches the dropping port 71, the push-up piece pushes up the operating rod against the spring 83.

Along with this, as shown in FIG. 9, the seedling drop bar 77 descends from the position shown by the alternate long and short dash line, and its end 7
7a contacts the root pot of the seedling frame 10. At this time, the crankshaft is approaching the bottom dead center, and therefore the rising speed of the push-up piece 40e is rapidly reduced, but the other end 77b of the seedling drop rod is located at the upper end Y of the acceleration means 79. Therefore, the descending motion of the rocking lever 75 thereafter is accelerated by the pivoting motion of the seedling dropping rod due to the collision with the accelerating means, and the end 77a of the rod snaps the seedling by the snapping motion. Let it fall. At this time, the accelerating means 79 relieves the collision force and the pressing force by the elastic deformation of the elastic member 79b, and prevents a strong impact force from acting on the seedlings. When the planting claw is lowered, the operating rod 82 is returned to its original position by the spring 83. Also, the seedling drop bar immediately returns to the horizontal position by the spring and rises together with the swing lever.

The dropped seedlings are received by the planting section located at the closest position from the dropping port and descend. When the crankshaft 37 approaches the top dead center, the planting claw 40b pierces the ridge, and further, the tip of the push rod 45 is
Further entry into hollow tube 46 causes push ring 45a to push hollow tube 45. As a result, the opening claw lever 46a is driven, and the front claw 41a moves to the fixed fulcrum 42 thereof.
It rotates in the forward direction around c, and at the same time, the rear claw 41b
Is driven to the opposite side via the claw levers 43a and 43b,
Rotating in the backward direction around the fixed fulcrum 42d, the planting claws are opened and the seedlings are placed vertically in the planting holes drilled by the both claws.

Next, the claw moves to the raising operation. At this point, the pin 33a of the swing arm 33 is located at the lower end of the guide groove 39 near the forward side. The descending force of the crankshaft, which has moved to the descending operation, first moves the pin 33a to the retreat side bulging portion 39a provided at the lower end of the guide groove. As a result, the connecting arm 31 pivots slightly to the retracted side, and accordingly, the planting claw 40b also slightly moves rearward. On the other hand, since the vehicle C is constantly moving forward at a constant speed, the backward movement of the planting claw 40b is offset by the forward movement of the vehicle C, so that the planting claw 40b can move against the seedling in the planting hole. It rises vertically and does not kill the seedlings. When the claw leaves the ridge, the push ring retracts and the claw is closed by the tension spring 44. And again, it rises toward the seedling drop opening. In the planting hole, a pair of mullers 48 squeeze and suppress the soil from both sides. During this one cycle, the seedling frame is fed by the feed claw 6.
By 4, only one pitch is sent. By repeating this, seedlings are continuously planted.

In the above embodiment, an electric motor is exemplified as the drive source, but it goes without saying that this may be an internal combustion engine, and both may be used together. Also,
The timing of the interlocking operation between the planting device P and the seedling supply section S is
Although a winding transmission device such as a sprocket has been exemplified, it goes without saying that a known means such as a combination of a position sensor and a step motor can be adopted.

[0037]

[Effect] Since the seedling raising device of the present invention is configured to partition the inside of the seedling box to define the seedling pot space by the seedling casing that holds the root pot from the side, the seedling casing is manually removed from the seedling casing. After that, it is very easy to separate the seedling frame and the root pot, and even in continuous planting with a planting machine, the detachment mechanism of the seedling is simple and light force is required, so seedlings that are common in mechanical planting Very little damage. In particular, since the root protrudes from the pot hole, it becomes impossible to separate the seedling, resulting in a missing portion of the seedling on the ridge, and manual replanting of the seedling. According to the planting method of the present application, since the seedlings can be supplied to the planting part by pushing the seedlings downward with a small force, the mechanism of the seedling supplying part of the planting machine is simplified and the lateral width is not taken. Even when applied to a planting device such as, there is an effect that the device can be downsized.
