It is pressed toward the wall 31a and packed in a box.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 11 show an apparatus for pretreatment of rush seedling transplantation. This pretreatment device comprises a working unit 1 for supplying a mother plant of a rush seedling G grown from a seed stock,
Cutting section 2 that cuts the tip of the stem and the end of the root while holding and transporting the rush seedlings G, and crushing the mother plant of the rush seedlings G flat, deforming and separating each planting plant. A transport unit (transport mechanism) 4 for pinching and transporting the separated rushes G, and a dropping unit 51 is provided in front of the working unit 1 and packed in a box below the transport unit 4 (Box packing mechanism) 52 is provided.

In the pre-processing apparatus, an angle member, a plate member, and the like are combined to form an L-shaped body 53 as viewed from the front, and a movable caster (moving wheel) 54 and a stationary positioning stopper 55 are provided below. Having. Reference numerals 5a and 5b denote a pair of wide endless rotating belts arranged opposite to each other, driven by the power of a motor (drive device) M, and are substantially horizontal from the working unit 1 to the cutting unit 2 and pass through the stock dividing unit 3. It is stretched in a substantially vertical direction to the transport section 4, and is configured to transport the rush seedlings G placed on the lower endless rotating belt 5a while nipping it with the upper endless rotating belt 5b.

In FIG. 1, the lower endless rotating belt 5a of the working unit 1 is provided with a tension pulley 5 from the right end (start end) side.
6a is slightly ascended (or may be horizontal) to an intermediate position where the rush grass G can be placed on the upper right side, and the upper endless rotating belt 5b is connected to the lower endless rotating belt 5a.
Has a right end (starting end) closer to the cutting portion 2 than the right end, and is inclined downward from the right end to a position halfway where the tension pulley 56b is located, and the upper endless rotating belt 5b is turned from the conveyed starting end facing the same. The interval is gradually narrowed toward the lower side in the moving direction, so that the rush seedling G can be easily inserted.

The endless rotating belts 5a and 5b are inclined in the width direction of the belt as shown in FIG. 3, and the rush plant G is placed in an inclined position such that the root side is on the lower side and the stem side is on the upper side. Is transported in that position. Each endless rotating belt 5
The sensors S1 and S2 for detecting oversized rush seedlings are disposed on the back side of the rush seedling G holding side of a and 5b.
1, S2 uses a contact type or non-contact type switch.

The endless rotating belts 5a and 5b move outwardly when the rush seedling G is sandwiched, and the movement of the belts 5a and 5b is detected by the sensors S1 and S2. These sensors S1 and S2 are off when the rush seedlings G are in a normal size, and when the oversized rush seedlings G are fed in and the movement of the endless rotating belts 5a and 5b in the facing outside direction is equal to or more than a certain value, The sensors S1 and S2 are turned on at the same time and detect it, and the endless rotating belt 5a,

It is preferable that the reverse rotation of the motor M is performed by a timer for a certain period of time and then stopped. In addition, after the excessively large rush seedlings G are artificially divided, the pretreatment device is restarted to perform reprocessing. Either of the sensors S1 and S2 may be used, but the endless rotating belts 5a and 5b may have different slacks or different tensions. For example, if the lower endless rotating belt 5a has much slack, Even if the rush seedlings G are small, they may operate or may not operate even if they are large, which may cause malfunction.

However, if two sensors S1 and S2 are provided, even if the sensors S1 and S2 operate at different timings as shown in FIG. 12, the two sensors S1 and S2 are finally turned on at the same time. Excess rush seedlings G are accurately detected. However, if the interval between the upper and lower tension pulleys 56a and 56b is detected by one sensor and the motor M is rotated in the reverse direction when the interval becomes longer than a certain value, accurate detection can be performed by one sensor. Becomes possible.

As shown in FIGS. 1, 3, and 4, the cutting section 2 holds the rush plants G near the ends of the substantially horizontal portions of the endless rotating belts 5a and 5b while holding and transporting the rush plants G by these belts. Disc-shaped cutters 6 and 7 are provided for cutting and trimming the tip of the base and the tip of the root to a predetermined length. Each of the cutters 6, 7 is composed of two upper and lower sheets, and the cut chips are allowed to fall downward from the left and right sides.

A solvent is stored in the container 60, and the cutter 7 rotates, so that the blades around the entire circumference are immersed in the solvent. As this solvent, if an insecticide, a herbicide, a germination promoter, etc. are mixed in addition to water, the cutter 7
Can be supplied to the roots of the rush seedlings G. In addition, this solvent can wash off soil adhering to the blade portion of the cutter 7, and can prolong the life of the cutting effect. The washed soil is retained in the container 60.

The container 60 is provided with a pair of front and back scrapers 61 which are in sliding contact with the surface of the cutter 7 in order to positively discharge the lower cutter 7. The scraper 61 is formed in a plate shape of hard rubber, plastic, or the like.
The cutter 7 is fixed so that its position can be adjusted in the distance direction and can be replaced. There is a small gap between the scraper 61 and the blade of the cutter 7 so that the scraper 61 is not ground by the blade.

On the inner side of the root-side cutter 7, rubber rollers 8, 8 are attached to the respective cutter 7 shafts, and the rubber rollers 8, 8 are located at a predetermined interval in the radial direction. The shoots of seedling G are not damaged. 62
Is a cutting root eliminating means provided in the cutting section 2, and an air compressor 63 and an air nozzle 63 connected to an air tank 64 are arranged facing the outer side surface of the cutter 7 on the root side.

Accordingly, the tip action portion makes an elliptical motion and scrapes the root portion for each small plant. The stock splitting claw 16 has two claw bodies 16a and 16b juxtaposed in the same direction or in a direction intersecting with the seedling feeding direction, so that the splitting action by the stock splitting claw 16 is close to a shearing action. Is performed.

A sensor S3 is provided at the end of the cutting section 2 or at an intermediate position of the cutting section 2 for detecting that the rush seedlings G are supplied to the stock dividing section 3. As the sensor S3, an optical sensor or a non-contact type sensor (a contact type sensor may be used) is used, and controls the claw driving unit 65 of the stock sorting unit 3. The claw driving means 65 of the stock dividing section 3 is capable of connecting and disconnecting the power from the motor M by an electromagnetic clutch 66. When the sensor S3 detects the carry-in of the rush, the electromagnetic clutch 66 is brought into contact. , The holding claws 15 and the stock splitting claws 16 are driven.

This is because if the claws 15 and 16 are constantly driven even when the rush seedlings G are not carried into the stock dividing section 3, the power loss is large, and the timing of the stock splitting when the rush seedlings G are suddenly carried in is increased. In some cases, the claws 15 and 16 are driven only when necessary, in order to prevent such misalignment. Note that the endless rotating bands 10a and 10b are constantly driven.

Each of the endless rotating belts 5 is located on the lower side of the transport from the location of the separation device 14 of the transport section (transport mechanism) 4.
a and 5b are formed in such a manner that the stems of the rush seedlings G after stock splitting are pinched and conveyed in a substantially adhered state, and a guide plate 67 for dropping guidance is provided below the placing guide plate 9, and the endless rotation is performed. Drop-feeding can be performed so that the divided seedlings can enter the seedling storage box 31 for storage and transportation from the transport end portions of the moving belts 5a and 5b.
