Is detachably connected. The basic structure of the band-shaped seedling producing machine T was previously filed by the applicant in Japanese Patent Application No. 2-210646 and a utility model registration application filed on Mar. 8, 1991 (Application No. 3-208814). The detailed description is omitted here, and the outline is explained below.

Reference numeral 19 is a seedling carrying belt of the band-shaped seedling manufacturing machine T, and 20 is a root aligning belt which rotates in synchronization with the seedling carrying belt 19. The root alignment belt 20 is covered with a safety cover 21 by exposing only the root alignment carrying surface 20a. A preliminary seedling stand 22 for storing pretreated seedlings in advance is arranged over the whole length of a seedling arranging section 28, which will be described later, above the seedling carrying belt 19 in the conveying seedling tip direction. A seedling holding and holding belt 23, a stem blade cutter 24, and a band-shaped seedling production section 25 are provided on the side. No. 26 is a tape that continuously joins the rush seedlings P in a strip shape. From the starting end of the seedling carrying belt 19 or the ending end of the guide rods 17 and 18 to the starting end of the seedling holding and holding belt 23, the roots of the supplied seedlings P are arranged and the seedlings are arranged, and the insufficient seedlings are supplied. A seedling arranging section 28 is formed, and its front side (right side in FIGS. 1 and 2) is a worker space 29 in which a worker is located.

As shown in FIG. 6, the safety cover 21 has an end inserted in the rear side of the root alignment belt 20, and an inverted L-shape so that the upper surface and the front side surface cover the upper surface and the front side surface of the root alignment belt 20. It is bent in a cross section, and downward insertion pins 21a are provided at the left and right ends of the center of the inside thereof. On the other hand, on the frame 11 side of the machine body to which the rooting belt 20 is attached, a support pipe 21b is projected upward, and by inserting the insertion pin 21a into the support pipe 21b, The cover 21 has a structure that can be detachably attached. Then, the swelling of the root portion of the seedling P is accommodated and guided between the root alignment belt 20 and the root alignment transport surface 20a, and mud and dust are collected from the gap 31 between the lower end and the root alignment transport surface 20a. A guide plate 32, which can be dropped due to its own weight and vibrations when arranging the seedlings, is provided so as to be fixed to the frame 11 side of the machine body and over substantially the entire length of the seedling arranging section 28.

The belt-shaped seedling manufacturing machine T has a seedling carrying surface of the seedling carrying belt 19 with a horizontal surface H. The rear side inclination angle α is inclined with respect to L = about 30 degrees so that the seedlings being conveyed can surely contact the rooting belt 20. As shown in FIG. 6, the spare seedling stand 22 is composed of a back plate 22a and a bottom plate 22b having an angled cross section in a side view, and the back side inclination angle β of the back plate 22a is the seedling carrying belt 19 described above. The front side of the bottom plate 22b is the upper end (rear end) of the seedling placing conveyor belt 19 while the bottom plate 22b becomes more horizontal and is formed in a front standing state with a size larger than the back side inclination angle α of about 60 degrees. ) Is as close as possible to Therefore, for the worker in the worker space 29, the seedling placing surface of the seedling placing and transporting belt 19 and the spare seedling stand 22 are faced to each other at a right angle depending on the direction of the shoulders and arms, and the work is facilitated. It becomes easy to take out and replenish the seedlings P from the seedling stand 22.

On the other hand, in the pretreatment device A, the transferred seedlings are placed on a horizontal plane H. It is arranged so as to be inclined at about 45 degrees with respect to L. Therefore, the belt-shaped seedling manufacturing machine T and the pretreatment apparatus A are integrally connected so that the inclination angle of the seedling conveying surface is about 15 degrees, and the height of the conveyed seedlings in the lower part in the direction of the stem and blade is high. The position of the root-alignment conveying surface 20a of the root-alignment belt 20 is made to substantially coincide with the lower height of the seedlings discharged from the feed rolls 16 and 16 so that the roots are constant.

In the state of FIG. 3, the seedling carrying belt 19 of the band-shaped seedling manufacturing machine T and the carrying device B of the pretreatment device A are arranged so that the seedling carrying directions are substantially aligned with the horizontal plane. As shown by the line XX in FIG. 3, the transfer side of the pretreatment device A is set so that the transfer direction of the transfer device B is γ = about 30 degrees with respect to the transfer direction of the seedling placing transfer belt 19. You may make it incline upright. With this configuration, the transferred seedlings are transferred downward by about 30 degrees with the stems tilted at about 45 degrees, which is advantageous in that the seedlings can be easily supplied to the transfer device B.

Next, the operation of the pretreatment device A for rush seedlings and the band-shaped seedling production machine T will be described. Collective seedlings collected from the nursery are placed on the supply guide 3a via the guide portion 37 for supplying seedlings. When first supplied, the subterranean stem part is caught in both stock conveyor belts 3 and 3, and then the stem body is caught in the start ends of the stem conveyor belts 1 and 1 and the intermediate conveyor belts 2 and 2. It is conveyed at a low speed at an inclined posture of about 45 degrees, and the stem tip is cut from the underground stem to a length of about 250 mm above by the stem tip cutter 4 which rotates at high speed in the upper part of the sandwiched part.

The root hair of the rhizome is cut by the left and right root-cutting cutters 5 and 5 which rotate at high speed in the process of being pinched and conveyed by the stock conveyor belts 3, 3 to a length of about 20 mm below the rhizome. , Transferred from the end of the stock conveyor belts 3 and 3 to the beginning of the device D, and the stem portion is held by the stem conveyor belts 1 and 1 and the intermediate conveyor belt 2.2 at two upper and lower positions. The needle-like projections 6 of the endless belt-like bodies 7, 7 that continue to be conveyed by the belts 1, 1 and the like and rotate at the same speed as the belts 1, 1 ... From the root and penetrate deep into the rhizome, and at the intermediate sprocket, the needle-like projections 6 swivel rapidly to extend the strongly entangled roots and separate the roots of the rhizome to release it. I do. At that time, the needle-like projections 6a of the endless strip 7 are located in a portion corresponding to the new shoots above the rhizome and unraveled in a reasonably comfortable manner, and the spatula-shaped projections 6b to the rhizome where the hard rhizome exists, 6b is located and strongly breaks while cutting the rhizome. After that, it retreats in sequence and withdraws from the slits of the guide plates 12, 12, and immediately after that, it is delivered to the exit belts 15 and 15 while being strongly held, and at the same time, the stem portion is released. Then, the sent underground rhizomes are sandwiched between the sending-out rolls 16 and 16 and pulled out at a speed higher than the conveying speed, so that the unraveled rhizomes are pulled in the conveying direction of the seedlings P and spread. It becomes an expanded thin layer seedling group.

In the delivery rolls 16 and 16, the loosened seedlings are smoothly delivered by the guide rods 37 and 37 without being wound around or rolled up on the rolls, and the stem wheel 39 also moves the stem tip side at the same speed as the stock root. The loosened seedlings are sent to the next process without disturbing the transportation. The seedlings in a thin layer discharged from the feeding rolls 16, 16 are supported by the stem tip receiving guide rods 17 from below, and the stems are guided by the stem retaining guide rods 18, It is transformed from a tilted posture of about 45 degrees to a tilted posture of about 30 degrees, and is transferred on the seedling carrying belt 19 of the band-shaped seedling manufacturing machine T while maintaining a thin layer state. It is desirable that the seedling group on the seedling placing and conveying belt 19 has a layer as uniform as possible, and the operator located on the side of the root aligning belt 20 adjusts the thickness appropriately. When the amount of seedlings is insufficient, the spare seedlings placed on the spare seedling placing table 22 are taken out as appropriate, and the seedlings discharged from the pretreatment device A are replenished so that the seedling layers are aligned, and the seedlings are also transported appropriately. Try to correct the posture of the seedlings.

Thereafter, the seedling group on the seedling placing and conveying belt 19 is conveyed to the lower side in the conveying direction, is held by the seedling holding and holding belt 23, and the stem tip is further cut by the stem cutter 24, and then the band-shaped seedlings are cut. It is sent to the production section 25 and the subterranean stems are formed into continuous strip-shaped seedlings connected by a tape 26.
