[Problem that the idea aims to solve]

Group seedlings such as rush seedlings or rice seedlings have long and tightly intertwined roots, so it is not necessary to divide them. It is difficult to divide the seedlings by force using the known unraveling device, and the growth of the seedlings is reduced. The point buds are damaged, resulting in poor growth after planting, and the long roots become a hindrance to planting. Ta. However, in the past, there was no appropriate means for solving such problems. So After developing various devices for cutting roots and repeating experiments, we were able to collect The size and shape of the root stock of grouped seedlings vary greatly, so please be careful when supplying seedlings and cutting roots. It was difficult to maintain seedlings.

0004

[Means to solve the problem]

This invention uses a root cutting cutter on the root side of the seedling holding and conveying path that leads to the root stock removal device. is arranged on the upper side of the root cutting cutter in the conveying direction, and the tip side is connected to the root cutting cutter. The base sides of the pair of plant base clamping and conveying belts that overlap with The stock clamping conveyor belt is supported by a large and swingable shaft, and the ammunition is mounted so that the clamping gap becomes narrower. The above-mentioned problem was solved by energizing.

[0005]

[Effect]

When collective seedlings with tightly entwined roots dug out from the nursery are fed to the pretreatment device, the collective The root stock of the seedling is sandwiched between the wide starting ends of the plant pinching conveyor belt, and The holding conveyance body adapts to the size of the roots and resists the bullets by expanding its gripping distance and increasing its strength. When the root cutting cutter is reached in a pinched state, the root cutting cutter is conveyed in a pinched state. Cut the roots of the existing stump short. Then the decoding device inherits it and performs the decoding process. However, the tangled roots are cut short, so they can easily be divided and damage the buds. There are very few.

0012 Figure 3 shows the transmission system, with the electric motor installed at the middle (height) of the pedestal. The output V-pulley 30 of the motor 28 is connected to the upper part of the V-belt 31 in the front-rear direction. The power is transmitted to the V pulley 33 of the intermediate shaft 32, which is supported as a The input of the girder sprocket 34 and the worm gear case 35 that reduces the speed by approximately 40:1. The chain 37 is put on the power sprocket 36, and the output sprocket 38 Tension the sprocket 39 of the rotating shaft 3 on the other side to which the sprocket 13 is attached. It is driven via a chain 41 to which a rotation roller 40 is attached, and is attached to the rotating shaft 3. The girder gear 42 is connected to the opposite rotation via gears 43 and 44 of the same diameter arranged laterally. The gear 45 attached to the rotating shaft 3 is driven, and the sprocket attached to these rotating shafts 3, 3 is driven. The sprockets 47, 47 of the vertical shafts 39a, 39a are attached to the chain 4. 8 and 48, and is attached to the shaft of one of the sprockets 13.

Since the gear 56 attached to the other rotating shaft 2 is driven, the stem end clamping belt 20 and the intermediate The clamping belt 21, the unraveling belt 12, the exit belt 18, and the delivery roll 19 (chain (via the pin 19a) rotates.

[0013] Further, a belt is connected to the feeding side of the intermediate shaft 32 in the front-rear direction via a coupling 57. A bell gear case 58 is interlocked and connected, and its output sprocket 60 and intermediate shaft 6 A chain 62 is stretched around the sprocket 61 of 1a and attached to this intermediate shaft 61a. Another sprocket 63 is attached to the sprocket 65 of the first cutter shaft 64 in the vertical direction. The lower part of this first cutter shaft 64 is interlocked with a chain 67 with a tension 66. One of the root cutting cutters 26 is attached to the lower side of the first cutter shaft 64. The attached gear 68 connects to the other root cutting cutter 2 via two gears 70 and 71 of the same diameter. 6 is engaged with the gear 73 of the shaft 26a to which the left and right root cutters are attached. The cutters 26, 26 are driven to rotate in reverse so as to cut the stem while sandwiching it, and cut the stem at the tip. A sprocket 25a attached to the shaft of the cutter 25 is attached to the upper part of the intermediate shaft 61a. It is driven by a sprocket 25b via a chain.

[0014] Next, to explain the function of the pre-treatment device for rush seedlings, the When the group of seedlings is placed on the entrance guide plate 17b and fed, first the roots are separated from both plants from the wide entrance. It is caught between the original belts 10 and 10, and at that time, even if the root stock is deformed, due to the speed difference The stem is conveyed while being rotated slowly, and then the stem is pinched at the tip of the stem. It is held between the starting ends of the holding belt 20 and the intermediate holding belt 21 and conveyed in an almost vertical position. Then, the tip of the stem is cut upward from the underground stem by a tip cutter 25 at the upper part of the pinched area. The hairs at the root stump are cut into lengths of approximately 250 mm, and the root hairs are of various sizes and shapes. However, it is conveyed in a state where it is strongly pinched by the left and right stock belts 10, 10. The entrance guide plate 17b should keep the end surface of the roots, which are growing and clustered, at a constant height. The roots hang down in the gap A at the rear, and the root cutting cutters 26, 26 The part close to the lower part of the position held by the stock belt 10 is removed from the underground rhizome. After cutting it to a length of about 20 mm downward, unravel it from the end of the stock belt 10 and transport it. It is ejected between the starting ends of the feeding belts 12, 12.

[0015] Next, the stem portion is connected to the stem end clamping belts 20, 20 and the intermediate clamping belts 21, 21. The root part continues to be conveyed while being held in two places (upper and lower), and the lower surface of the root part is the exit point. It is conveyed in a stable state on the guide plate 17b, and in this state the unraveling conveyance belts 12, 1 The guide plate 17 moves the needle-like protrusions 11... The intermediate sprocket 15 advances through the slit and penetrates deeply into the root part in sequence. At site 15, needle-like protrusions 11... rapidly rotate and stretch the tightly entangled roots. The roots are cut short so that each root stock can be easily separated. Release it, and after passing it, it will retreat one by one and slip out through the slits in the guide plates 17, 17. Immediately after that, it is transferred to the exit belts 18, 18 and conveyed while being tightly pinched. , the stem part becomes released almost at the same time, and the sent-out root part is transferred to the delivery rolls 19, 19. Since the seedlings are caught between the two and pulled out at a higher speed than the transport speed, the seedlings become thin film-like strips.

[0016] In the above-mentioned example, root cutting, stem tip cutting, and cutting are carried out while transporting the seedlings in a substantially vertical position. The rotating shafts 2 and 3, the vertical intermediate shafts 39a and 39b, etc. are moved in the vertical direction to perform Although the illustration shows that the axes are set as If you transport the seedlings at an angle, for example, at a 45 degree angle, the feeding section will be tilted. If a diagonal receiving plate is provided to receive the stem, and the root end is received by the entrance guide plate 17b, By simply putting the seedlings in, the feeding position and posture can be specified, making feeding work easier. In addition, the tip of the stem cut by the tip cutter 25 is prevented from falling outside the conveyance path. This will not cause transmission failure or processing failure.

[0017]

[Effect of the idea]

In this invention, as mentioned above, the roots are placed on the root side of the seedling holding and conveying path leading to the root stock breaking device. A cutting cutter 26 is disposed, and a tip side is disposed on the upper side of the root cutting cutter 26 in the conveying direction. The base side of the pair of plant base clamping conveyance belts that overlap with the root cutting cutter 26 is held between the seedlings and Supported swingably at intervals wider than the width of the conveyance path, this stock clamping conveyance belt is clamped. Since the force was applied using a bullet to narrow the gap, the size or shape of the seedlings may be uneven. Even if it is possible to easily supply it, it is difficult to transport it by holding the stocks. The belt adapts to the size and shape of the root stump while resisting the bullets, firmly holding and transporting it. In addition, the appropriate position of the root can be set by the root cutting cutter 26 in this pinching and conveying state. It is possible to cut more accurately, and the root stock can be unraveled with the roots cut short. Since the plants are separated by can prevent damage to the new shoots.
