Description

  The present invention relates to a sugarcane cutting machine, and more particularly, to a sugarcane cutting machine that cuts sugarcane stems to produce seedlings.

  Sugarcane (hereinafter sometimes referred to as “millet”) has a plurality of nodes along the length of its stem, and one bud per node, so a millet seedling (hereinafter referred to as “millet seedling”) is used. Cut to include the clause. It is known that millet seedlings obtained by cutting millet into a length including two nodes have a high germination probability. Millet seedlings containing two knots are said to be two shoots (or two knots). Place millet seedlings or two shoots along the cocoon and sprinkle with soil.

  In the past, two millet seedlings were produced by manually cutting the millet using a sickle, but it was a problem that labor was applied or the worker could be injured. Moreover, when making 2 bud seedlings, it must be cut so that the shoots of the millet seedling are not crushed or the cut end of the millet seedling is not crushed.

  Japanese Patent Application Laid-Open No. 10-313611 describes a device for cutting millet between nodes by means of a rotary disk cutter. Therefore, it is necessary to manually adjust the cutting position for each one-node cutting, and there is a problem of poor work efficiency, and the risk of cutting work is high.

Japanese Patent Laid-Open No. 10-313611

  The present invention provides a sugarcane cutting machine that is safe, labor-saving, simple in construction, has high work efficiency, is free of chips, and does not crush the cut when making millet double shoots. To do.

  The present invention provides a pair of rotating bodies in which each rotating shaft exists on the same plane, and each rotating body extends at least one sugarcane cutting blade and rotating shaft extending radially outward from the rotating shaft. A plurality of rubber members extending radially outward from each other, and the pair of rotating bodies is a sugarcane cutting machine having a cutting blade and a rubber member corresponding to each other, and the pair of rotating bodies are in opposite directions to each other When one cutting blade of a pair of rotating bodies and the corresponding cutting blade of the other rotating body are aligned with each other, both cutting blades bite the sugar cane between them and cut the sugar cane When one rubber member of the pair of rotating bodies and the corresponding rubber member of the other rotating body are aligned, the sugar cane is bitten between the rubber members, and the sugar cane is rotated by a pair. At a peripheral speed corresponding to the rotational speed of the body It is configured to feed between a pair of rotating bodies, and the number of cutting blades and the distance between the tip of the cutting blade and the rotation axis center are configured such that sugarcane to be cut includes two nodes. To do.

  The plane on which the rotation axis of the pair of rotating bodies exists can be horizontal, vertical, or an arbitrary angle with respect to the ground.

  According to the present invention, the cutting blade is engaged with the seedling at a substantially right angle, so that the cut end of the seedling becomes a substantially right angle with the stem, and two bud seedlings can be obtained without crushing the cut end. By cutting the millet seedling vertically, the surface area of the cut end is reduced, the moisture in the millet seedling is prevented from evaporating, the freshness of the millet seedling is maintained, and germination is accelerated. Further, since the rubber member attached to the rotating body is used to feed the millet, the shoots of the millet seedling are not damaged. Moreover, since the sugarcane cutting machine of this invention is itself compact, it is easy to carry. Therefore, by using the sugarcane cutting machine of the present invention in combination with a generator, it is possible to work to make two sprout seedlings at any place, for example, in the field or at home.

  1 to 4 show a sugarcane cutting machine of the best mode for carrying out the present invention. FIG. 1 is a schematic front view of a sugarcane cutting machine 1, and FIG. 2 is a side view thereof, showing a state in which a front plate of a housing 11 and a pair of rotating bodies installed inside the housing 11 are removed. Yes. A hopper 13 is attached to the upper plate of the housing 11, and an opening provided corresponding to the hopper 13 is provided in the upper plate. Millet is inserted from the hopper and fed into the housing 11 through the opening of the upper plate of the housing 11. A pair of circles 14 indicated by a two-dot chain line indicates a locus of the cutting blade tip when the cutting blade attached to the rotation shaft rotates. The rotating shaft of the rotating body is rotated by a chain driven by a chain 16 by a motor 15 installed on the top of the housing 11. Between the four legs 12 that support the housing 11, a suntenna (not shown) for receiving millet seedlings that are cut and dropped is disposed.

  FIG. 3 is a cross-sectional view taken along line AA in FIG. 1 and shows a plan view in which a pair of rotating bodies 20a and 20b is attached to the housing 11. As shown in FIG. However, in order to simplify the illustration, the cutting blades, the rubber members, and their supports extending radially from the rotating body are not shown. When the gears 22a and 22b attached to the rotating shafts 21a and 21b of the respective rotating bodies 20a and 20b are engaged with each other at 23 locations, and one rotating shaft 22a is driven by the motor 15 via the chain 16 and rotated. The other rotating shaft 22b follows and rotates in the direction opposite to the rotating shaft 21a. If the gears 22a and 22b are formed in the same shape and the same number of teeth, the rotation shaft 21b has the same rotation speed as the rotation shaft 21a.

  FIG. 4 is a cross-sectional view taken along line BB in FIG. Cutting blade supports 24 and rubber member supports 25 are provided radially on rotating shafts 21a and 21b made of metal such as iron. The cutting blade support 24 and the rubber member support 25 are also made of metal such as iron. The rotary shafts 21a and 21b may be made of iron and cast integrally with these supports, or may be attached by welding to the rotary shafts 21a and 21b. Respective cutting blades 26 or rubber members 27 are attached to the outer sides of the supports 24 and 25 in the radial direction.

  The cutting blade support 24 and the cutting blade 26 are each provided with a through hole, and are fixed with a nut through a bolt through the through hole. In the illustrated example, the rubber member 27 is fixed to the rubber member support 25 with bolts through the through holes provided at both ends of the rubber member, with the center of the rubber member being looped, and fixed with nuts.

  As shown in FIG. 3, the rotating shaft 21a and the rotating shaft 21b rotate in synchronization with the gears 22a and 22b. Therefore, if the cutting blades of both rotating bodies are attached to the rotating shafts 21a and 21b so that the cutting edges coincide with each other. The blade edge coincides with each rotation. If sugar cane is present at a location where the cutting blades of both rotating bodies coincide on the same plane, the sugar cane is cut at that location. In the example shown in the figure, two cutting blades are attached to each of the rotating shafts 21a and 21b. Therefore, when the rotating body rotates once, sugarcane is cut twice. If the circumferential distance between the cutting edges on the circle 14 of the trajectory (indicated by a two-dot chain line) of the cutting edges of the two cutting blades of each rotating body is configured to include two sections of sugar cane, Two shoots can be made by cutting.

  FIG. 5 is a schematic front view of another embodiment of the present invention. The sugar cane is horizontally inserted into a sugar cane cutting machine and cut with the plane including the rotation axes of both rotating bodies formed in the same manner as shown in FIGS. Two seedlings obtained by cutting sugarcane are dropped and stored in a santenna placed below.

  The sugarcane cutting machine 1 shown in FIGS. 1 to 4 was produced as follows. The casing 11, the legs 12, and the hopper 13 were all made of iron plates. If an aluminum plate is used instead of the iron plate, the weight can be reduced. The unit of the dimension of the housing 11 is mm. In addition, since the lower part of the housing | casing 11 is a location where the cut sugarcane falls, the lower board is not provided. As the rotating shafts 21a and 21b of the rotating body, shafts having a diameter of 40 mm were used. The cutting blade support 24, using an iron material having a rectangular cross section, the width of the side surface (the length of the cutting blade) to which the cutting blade 26 is attached is 150 mm. The cutting blade was fixed to the cutting blade support by inserting a bolt into a hole penetrating both of them and tightening with a nut. The rubber member support 25 was made of an iron material having a rectangular cross section, and the rubber member having a rectangular cross section was fixed with a bolt and a nut. The cutting blade 26 was made using an iron material. In this example, as shown in the figure, two cutting blades 26 were attached to any rotating body in the same straight line, and the linear distance between the cutting edges of both cutting blades was 200 mm. When the cutting blade 26 rotates, the circumference of the trajectory of the cutting edge moves is 200 (mm) × π, and the circumferential distance between the cutting edges of both cutting blades is 100 (mm) × π. Become. Therefore, 100 × π (mm) ≈31 cm is the sugarcane cut length. Actually, since the average diameter of millet is 2 to 3 cm, the contact diameter is small, and the length of millet seedling is about 29 cm. Usually, since the width of Santana which accommodates millet seedlings is 30 cm, the linear distance between cutting edges is set so that the length of millet seedlings is about 29 cm. Since the length of the sugar cane nodes is 15 cm long and about 5 cm short, two shoots are obtained by the sugar cane cutting machine of this example.

  Standard spur gears (module 2.0, number of teeth 100, pitch circle diameter 200 mm) were used as the gears 22a and 22b attached to one end of the rotating shafts 21a and 21b of both rotating bodies.

  As a motor for driving the rotating body, a motor having a voltage of 100 V, 0.4 W and a reduction ratio of 1/30 was used. Sugarcane was cut at a processing speed of about 80 lines / minute. The number of treatments per hit was 3,200, which could be cut in about 40 minutes. It should be noted that millet can usually be inserted into the sugarcane cutting machine of this embodiment two at a time, and at most three can be inserted, and the processing speed is doubled and tripled to further increase the work time. It was shortened and it was possible to work safely, and two shoots of the same size could be obtained. If this cutting operation is performed manually with a sickle, it takes 4 to 5 hours.
