[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of continuously transferring a pot seedling fed from an end of an endless conveyor belt rotatably supported on a machine body to a planting device comprising a pair of disks rotating in the same direction. More particularly, the present invention relates to a pot seedling transplanter capable of freely adjusting the inter-strain (planting interval) in a wide range.

2. Description of the Related Art As a transplanter for pot seedlings, there is a real plant 1-4.
No. 2977 and Japanese Utility Model Publication No.
A row of pot seedlings pushed out of the pot seedling box on the seedling mounting table by the push rod are supplied to a pair of conveyor belts rotating in opposite directions by a seedling receiving arm waiting in front of the seedlings. It is described that the belt is fed from the edge of the belt to an implanting device below and is continuously implanted.

This will be described in detail with reference to FIGS. 4 and 5. In the pot seedling transplanter, a flexible pot seedling box 1 having a large number of pot seedling chambers connected in series is provided with a seedling mounting table. 2 is intermittently fed one row at a time, and a push rod 3 provided at a predetermined position behind the seedling mounting table 2 protrudes from a bottom surface into a row of pot seedling rooms 1a of the pot seedling box 1 from the bottom. Is pushed forward and into the seedling receiving groove 4a of the seedling receiving arm 4 provided forward (shown by a solid line in FIG. 4). Subsequently, the seedling receiving arm 4 that has received the potted seedlings rotates downward while reversing the potted seedlings in the reverse direction and supplies the seedlings to the upper surface of the transport belt 5 (shown by phantom lines in FIG. 4). Reference numeral 6 denotes a spring member for pushing out the pot seedling from the seedling receiving groove 4a.

The conveyor belt 5 is composed of a pair of endless belts rotating in opposite directions, and the pot seedlings supplied on the conveyor belt 5 are transferred horizontally on the conveyor belt 5 toward the edge. When it reaches the edge, it falls into the seedling receiver 7, and then the feed claw 8 located above the seedling receiver 7 descends and sends the pot seedling downward from the swingable seedling receiver 7. The sent pot seedlings are pinched by a pair of endless descending belts 9, descend while keeping the horizontal posture, and supplied to the planting device 10 at the lower end of the descending belt 5.

[0005] The planting apparatus 10 is composed of a pair of disks which are arranged opposite to each other at a slight angle and are rotated in the same direction. It is lowered by the cutting blade 11 into a groove formed on the ground surface. Implanting is immediately performed on the pot seedlings (using a mulling wheel described later), and at the same time, the holding by the planting device 10 is released to complete the transplantation. Here, the planting device 10 rotates via the rotating mechanism of the descending belt 9, and the rotation speed of the planting device 10 is set so that the pot seedlings are planted almost vertically on the ground surface (hereinafter, such as this). In this state, the rotation speed of the planting device and the traveling speed of the machine are synchronized.) The lowering speed of the lowering belt 9 is adjusted according to the peripheral speed of the planting device 10.

Next, a driving system of the traveling device, the planting device 10 and the like in the pot seedling transplanter will be described with reference to FIGS. 6 and 7. FIG. First, the power of the engine 15 is transmitted to the shaft 17 in the reduction case 16 and transmitted to the wheels 20 via the switching gear 18 for switching the traveling speed, the drive shaft 19 and the like. At the same time, the driving force transmitted to the shaft 17 is transmitted to the pot seedling supply unit 24 via the gears 21 and 22 and the supply unit shaft 23 (a mechanism for feeding the pot seedling to the descending belt 9; The gear 2 is transmitted to the claw 8), and the gear 2
5, 26, planting seedling plant 2 via planting plant shaft 27
8 (the descending belt 9 and the planting device 10). Reference numeral 29 denotes a clutch for transmitting or interrupting the driving force to the supply shaft 23.

Now, in such a transplanter for pot seedlings,
If the rotation speed of the planting device 10 and the running speed of the machine are synchronized, the pot seedlings are transplanted vertically to the ground surface. If they are not synchronized, the pot seedlings are dragged by the planting device 10 and moved forward. Normal transplantation work cannot be performed, such as planting with a slant or conversely, and in the reverse case, transplantation work is impossible in some cases. That is, when the traveling speed of the body is determined, the ideal rotational speed of the planting device is uniquely determined. Conversely, when the rotating speed of the planting device is determined, the ideal traveling speed of the aircraft is also uniquely determined. In the pot seedling transplanter, the gear ratios of the gears 21, 22, 25, 26 and the like are set such that the rotation speed of the planting device 10 and a certain running speed of the machine body (referred to as working speed) are synchronized. I do.

In the pot seedling transplanter, the power of the planting section 28 is transmitted via the gears 25 and 26 to the planting section shaft 2.
3, the supply speed of the pot seedling from the supply unit 24 to the rotation speed of the planting apparatus 10 (also referred to as a supply pitch) is always in a constant proportional relationship. Due to such a structure, in the pot seedling transplanter, as long as the rotational speed of the planting device 10 and the running speed of the machine are kept in synchronization, transplantation can be performed only between certain plants set at the time of factory shipment. .

[0009] In the transplanter for pot seedlings,
If it is desired to make a change between the plants even if the rotation speed of the planting device 10 and the running speed of the machine are slightly sacrificed, the gears 21 and 22 are replaced and the gear ratio is changed. The driving speed of the seedling plant 28 is changed. However, in this case, since the rotation speed of the planting device 10 is not synchronized with the traveling speed of the airframe, there is an inconvenience that the pot seedling is transplanted while being inclined forward or backward, and the change between the plants is at most about ± 15%. Can be performed only within the range.

[0010]

As described above, in the transplanter for pot seedlings described above, transplantation can be performed only at a certain fixed traveling speed (working speed). Also,
In the transplanter for pot seedlings, it is possible to change the strain only within a certain limited range, and even in such a case, there is a disadvantage that the pot seedlings are transplanted with an inclination.

The present invention has been made in view of the problems of the above-mentioned conventional transplanter for pot seedlings, and allows a large changeable range between strains. Obtain a versatile transplanter for pot seedlings that can easily cope with seedlings of various vegetables, etc. In addition, even if the running speed of the machine is changed, the rotational speed of the planting device and the running speed of the machine are always synchronized. It is an object of the present invention to obtain a pot seedling transplanter that can vertically plant pot seedlings on the ground surface.

[0012]

SUMMARY OF THE INVENTION The present invention relates to a planting device comprising a pair of disks rotating in the same direction, for transferring a pot seedling fed from an edge of an endless transport belt horizontally supported rotatably to an airframe. In the pot seedling transplanter configured to supply, the drive system of the planting device is branched from the drive system of the traveling device, and the ratio between the rotation speed of the planting device and the rotation speed of the traveling device is always constant. In addition, the supply speed of the pot seedling to the planting device is made variable with respect to the rotation speed of the planting device, and the supply of the pot seedling including the endless conveyor belt is changed.
Including a clutch that controls the activation and deactivation of the feeder, and a planting device
A clutch to control the operation-stop of the pot seedling planting part.
The two clutches can be simultaneously connected or disconnected . And more specifically, pot seedlings
The planting section includes an endless descent belt that supplies the pot seedlings fed from the edge of the conveyor belt to the planting device, and the planting device is rotated via a rotating mechanism of the descent belt. In the present invention, the drive system of the traveling device means a power transmission system from the engine to the wheels, and the drive system of the planting device is a power transmission system branched from the drive system of the traveling device and leading to the planting device. Means

[0013]

In the pot seedling transplanter described above, the ratio between the rotation speed of the planting device and the rotation speed of the traveling device is always constant (this is not always the case with conventional pot seedling transplanters). Therefore, even if the running speed of the body changes, the rotational speed of the planting device does not become out of sync with the running speed of the body, and the inconvenience that the pot seedling is inclined forward or backward and transplanted does not occur. Then, the supply speed of the pot seedling to the planting device is made variable with respect to the rotation speed of the planting device (the conventional transplanting machine for pot seedlings is not variable,
In other words, since there was always a constant proportional relationship), it is possible to freely select the pot seedlings within an arbitrary range.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pot seedling transplanter according to the present invention will be described below with reference to FIGS. The description of has been omitted. The overall view of the transplanter for pot seedlings is shown in FIG. Etc. are arranged.

FIG. 2 shows the drive system of this pot seedling transplanter.
Referring to FIG. 3, the power of the engine 15 is transmitted to the shaft 17 in the reduction case 16 and transmitted to the wheels 20 via the switching gear 18 for switching the traveling speed, the drive shaft 19, and the like. In addition, the driving force of the driving shaft 19 is transmitted to the shaft 32, and further the planting portion shaft 2
7, and is transmitted to the pot seedling planting section 28. On the other hand, the power transmitted to the shaft 17 is transmitted through the gears 21 and 22, the shaft 33, the supply shaft 23, and the like.
4 is also transmitted. Reference numeral 34 denotes a clutch for transmitting or interrupting the driving force to the planting portion shaft 27, and reference numeral 35 denotes a bearing that allows the shaft 32 and the shaft 33 to freely rotate with each other.

In this pot seedling transplanter, since the power of the planting device 10 is taken out from the drive shaft 19 of the wheel 20, the gear ratio of each gear is appropriately set, and the rotation speed of the planting device 10 is adjusted to the body speed. It can always be synchronized with the running speed. Therefore, it is possible to perform a normal transplant operation at all the vehicle running speeds. Further, since the drive system of the planting device 10 is cut off from the supply shaft 23 in this manner, the supply speed of the pot seedling from the supply unit 24 to the planting unit 28 can be freely changed by exchanging the gears 21 and 22. You can now. Therefore, it has become possible to cope with various pot seedlings that differ greatly between strains with one transplanter.

In the pot seedling transplanter, the planting section 2
8 and the clutch 29 of the supply unit 24
One of to allow connecting or disconnecting at the same time the clutch lever, simultaneous operation of seedlings supply unit 24 and the planting unit 28, so that it is simultaneously stopped. This is because, for example, when reversing the direction of the transplanter at the end of the field, the clutch 29
Is disconnected and the clutch 34 is connected, the pot seedlings already supplied to the descending belt 9 and the planting device 10 are transplanted to unnecessary places. This is because there is an inconvenience that the transplant does not start for a while even if it is attempted to be transplanted.

[0018]

According to the present invention, a versatile transplanter for pot seedlings can be obtained in which the changeable range of the pot seedlings to be transplanted between the strains can be made large and various kinds of seedlings different between the strains can be easily handled. be able to. Furthermore, even if the running speed of the airframe is changed, the rotational speed of the planting device and the running speed of the airframe are always synchronized, and a normal transplant operation can be performed.
