Description

[Detailed explanation of the idea] [Industrial application field]

The present invention is a paper cylinder seedling transplanting device, more specifically, a seedling supply conveyor that conveys paper cylinder seedlings in a direction perpendicular to the direction of movement of the machine, and a paper cylinder seedling conveyor that transports paper cylinder seedlings perpendicularly to the direction of movement of the machine. The present invention relates to an improvement of a paper tube seedling transplanting device equipped with a seedling transfer conveyor that feeds seedlings from a cutting line direction to a rotating seedling transplanter.

[Conventional technology]

As this type of paper tube seedling transplanting device, for example,
There is one described in Publication No. 58-47401, which is
A seedling planting device, which is constructed with a seedling supply conveyor running in a direction perpendicular to the direction of movement of the machine body, and rotates paper cylinder seedlings fed out from the sending end of the seedling supply conveyor vertically in the direction of movement of the machine body. A pair of left and right clamping belts are stretched vertically between the seedling supply conveyor and the seedling planting device, and the paper cylinder seedlings are pinched and conveyed by the pair of clamping belts to feed the seedlings to the seedling planting device. is supplied from the direction of the cutting line.

[Problem that the idea aims to solve]

In order to perform simultaneous multi-row transplantation by erecting multiple seedling transplanters in parallel and supplying paper tube seedlings to each one at the same time,
In order to minimize the installation space required for installing multiple paper tube seedling transplanting devices with the above configuration on the same device, the clamping belts of each device should be tilted so that they overlap and are adjacent to each other. It is conceivable to install the paper tube seedlings in a vertically rotating direction, but the angle of inclination is limited to about 30 degrees horizontally from the vertical line. Accurate delivery will not be possible. The purpose of the present invention is to increase the inclination angle of the conveyor that feeds the paper tube seedlings fed out from the seedling supply conveyor to the seedling transplanter, thereby minimizing the installation space for multiple paper tube seedling transplanting devices, and in addition, To ensure that cylindrical seedlings are delivered to a seedling planting device in a normal posture.

[Means to solve the problem]

Reference numeral 16 denotes a seedling supply conveyor, which is installed on the machine body 1 so as to convey the paper tube seedlings P in a direction perpendicular to the direction of movement of the machine body 1. Reference numeral 3 denotes a seedling planting device, which is mounted on a shaft on the machine body 1 so as to face the direction of movement of the machine body 1 and rotate within a vertical plane. Reference numeral 17 is a seedling transfer conveyor that transfers the paper cylinder seedlings P conveyed by the seedling supply conveyor 16 to be supplied to the seedling planting device 3. The seedling transfer conveyor 17 has its lower end portion vertically disposed to face the seedling receiving portion of the seedling planter 3, and its portion above the lower end portion thereof is diagonally disposed. Reference numeral 38 denotes a clamping member disposed opposite to the lower end of the vertically installed seedling transfer conveyor 17, which clamps the paper tube seedlings P being conveyed by the lower end.

[Effect]

Since the seedling transfer conveyors can be arranged side by side in a relatively narrow installation space in a state of overlap, it is suitable for simultaneous multi-row transplanting, and even in that case, it is possible to normally transfer and supply paper tube seedlings to the seedling transplanter. This can be done reliably in a comfortable position.

【Example】

The illustrated embodiment will be described in detail below. Reference numeral 1 denotes the aircraft body, which is moved in the direction of arrow A by a towing vehicle such as a tractor (not shown). A pair of suppression drive wheels 2 are provided at the rear of the aircraft 1 so that the aircraft 1 rotates while touching the ground as the aircraft 1 advances.A seedling planting device 3 is installed in front of the suppression drive wheels 2, and an opener is installed below the aircraft 1. 4 is provided so that the seedling planting device 3 can be rotated within the open rear part of the opener 4. The seedling planting device 3 is made of a pair of rubber or other elastic discs, the upper part of which is opened in the shape of a lip by an appropriate means, and the side of the device in the direction of movement of the device 1 has a large number of guide rolls provided along the circumference. 5 to close it by pressing it from the outside. A shaft 6 is provided at the center of the suppression drive wheel 2 and rotates therewith, and between a chain wheel 7 fixed to the shaft 6 and a chain wheel 9 on a shaft 8 provided at the center of the seedling planting device 3. A chain 10 is stretched between the two so that the two rotate in the same direction. Further, a bevel gear 11 is provided on the shaft 8, and the shaft of the bevel gear 12 that meshes with the bevel gear 11 is used as a drive shaft 13, which extends in the direction of movement of the machine body 1 and has chain wheels 14 and 15 fixed to its ends for planting seedlings. Each part that supplies the paper tube seedlings P to the attachment device 3 is driven. The paper tube seedlings P are supplied by a seedling supply conveyor 16 provided to run in a direction perpendicular to the drive shaft 13, that is, in a direction perpendicular to the direction of movement of the machine body 1, and a conveyor conveyor 16 extending downward facing the conveying end thereof, as described below. This is done using the seedling transfer conveyor 17. The seedling supply conveyor 16 is usually composed of a flat belt or a string belt, and the paper tube seedlings P are lined up in a row and conveyed to the machine 1.
Convey in a direction perpendicular to the direction of travel. A seedling holding roller 18 with a sponge is provided above the conveying end of the seedling supply conveyor 16, and a chain wheel 20 is fixed to its shaft 19 and interlocked with the chain wheel 14 of the drive shaft 13 by a chain 21. A gear 22 is fixed on the top and is meshed with a transmission gear 24 provided on the shaft 23 of the seedling supply conveyor 16 so that the gears rotate in opposite directions at the same speed. For this reason, paper tube seedlings P on the seedling supply conveyor 16
The seedlings are held down by a seedling holding roller 18 rotating at the same speed as the seedlings, and then fed out forward.
The paper tube seedlings P that have been fed out are separated into individual seedlings by a protrusion 25 of a seedling transfer conveyor 17 whose upper end is positioned in front of the feeding end. On the other hand, the seedling transfer conveyor 17 has a driving pulley 26 at the bottom and driven pulleys 27 and 28 at the top and middle.
(The axes are 27' and 28') are provided,
The driven pulley 28 rotates between these
The lower end of the delivery located between the drive pulley 26 and the drive pulley 26 is vertically installed, and the part above it is provided diagonally, and the upper end is connected to the delivery end of the seedling supply conveyor 16 as described above. It is located in front of the The seedling transfer conveyor 17 runs 5 to 20 times faster than the seedling supply conveyor 16, and is set so that the tip speed of the protrusion 25 on its surface is approximately the same as the circumferential speed of the seedling planter 3. Therefore, a chain 31 is stretched between the small chain wheel 30 of the intermediate shaft 29 and the chain wheel 15, and the chain 31 is stretched between the large chain wheel 32 of the intermediate shaft 29 and the shaft 3 of the drive pulley 26.
A chain 35 is stretched between the chain wheel 34 of No. 3 to speed up the rotation of the drive pulley 26. The width of the seedling transfer conveyor 17 is narrower than the length of the paper tube seedling P, and the seedling transfer conveyor 17 receives the paper tube seedling P with its head protruding. The protrusions 25 are made of rubber or a similar elastic material, so that they deform appropriately when they come into contact with the paper tube seedlings P fed out from the seedling supply conveyor 16. be able to. Although the paper tube seedlings P are separated from the succeeding paper tube seedlings P and enter between the protrusions 25 and 25 and are held in a pinched state, the paper tube seedlings P are likely to fall due to vibrations of the machine body 1 due to the above-mentioned oblique installation, so the seedlings A pair of left and right seedling guides 36 are positioned opposite to each other on the surface of the conveyance path in the upper part of the transfer conveyor 17 in an oblique state, and are supported by a bracket 37 fixed to the machine body 1. The lower end of the seedling guide 36 is curved downward to prevent the paper tube seedlings P from falling off. This seedling guide 36
It is preferable to use a wire body or a narrow plate body to reduce frictional resistance as much as possible. Further, below the seedling guide 36, a pair of left and right pinching members 38 are provided, and a floating pulley 28 and a driving pulley 28 are provided.
It is provided along the conveyance path in a vertically arranged state between 6 and 6. This clamping member 38 is usually made of a resilient material such as a leaf spring, and has one end attached to a bracket 39.
The other end is extended to a position opposite the seedling receiving part which is the opening of the seedling transplanter 3, and the paper tube seedling P is clamped between the vertically installed parts of the seedling transfer conveyor 17 to ensure that it remains in its normal posture. It is designed so that it can be supplied to the seedling planting device 3 at any time. 40 is a gear case, and 41 is a seedling stand for temporarily storing paper tube seedlings P. The paper tube seedlings P supplied to the seedling planting device 3 are closed from the outside by the guide rolls 5, are held and conveyed downward, and are released into the groove made by the opener 4, and are driven by a pressing drive. It is crushed and planted by Ring 2. In addition, when it is installed in a multi-row transplanter for planting in particular with narrow row width, as shown in Fig. 3,
It is preferable to provide a floating roller 42 at the intermediate portion of the conveyance of the seedling supply conveyor 16 so that the inclination angle of the sending end side of the seedling supply conveyor 16 is steep so that it can face the seedling transfer conveyor 17 at right angles as much as possible. Then, even if the inclination angle of the upper part of the seedling transfer conveyor 17 is set to 60 degrees or more, the paper tube seedlings P can be accurately transported and reliably supplied to the seedling planting device 3 in a normal posture.

[Effect of the idea]

As is clear from the above, the present invention transfers paper tube seedlings, which are conveyed by a seedling supply conveyor in a direction perpendicular to the direction of movement of the machine, to a seedling planting machine that rotates vertically in the direction of movement of the machine. Since the lower end of the seedling transfer conveyor that feeds from the cut line direction is placed vertically and faces the seedling receiving part of the seedling planting device, paper tube seedlings can be fed to the seedling planting device in a normal posture. It can be carried out reliably as it is. In addition, since the part above the lower sending end of the seedling transfer conveyor is installed obliquely, the installation space on the machine body is relatively small when the device of the present invention is installed in parallel for multi-row transplantation. Enough. Furthermore, since the feeding lower end portion is provided with a pressing member that pinches the paper tube seedlings being conveyed by the feeding lower end portion, the paper tube seedlings will not lose their posture or fall off. In particular, since there is no need to stretch a pair of left and right holding belts to transfer and supply the paper tube seedlings to the seedling planter as in the conventional method, the structure is simple and economical.
