量や寸法も大きくなるという欠点があった。(Conventional technology and its problems) Grass mowers, which have traditionally been used for the purpose of cutting weeds, are also known as brush cutters and have a speed of 8°000 to 9,000 m/min.
It rotates an exposed blade at a high speed of 00 revolutions. Therefore, in addition to its own risks,
During work, the rotary blade hits hard objects such as stones hidden in the bushes, and the flying fragments often cause eye injuries, which has become a problem. F11 According to a nationwide survey conducted by the Faculty of Medicine of Okayama University, 14 people lost their eyesight in the year 1985.
It has been found that 0 times as many people suffer serious eye injuries (Nihon Keizai Shimbun, December 1, 1985).Also, this method uses a circular knife with a diameter of 20 cm or more that rotates at high speed. Although it is suitable for heavy work in mountains and forests, such as cutting down to shrubs, using this method when the purpose is to cut thinner and softer weeds than usual requires more energy and power than necessary. As a result, the weight and size of the mower itself increases.

れる。(Function) To explain in detail the present invention having the above configuration, the motor or '' transmits the rotational force of a driving source such as an engine to two rotating bodies that are in contact with each other on the outer circumferential surface via a transmission mechanism and a rotating shaft. When the two rotating bodies are rotated, they are driven to rotate in opposition to each other. When this rotating contact part is pressed against an object to be cut, such as a weed, the object to be cut is caught and held by the contact part of the rotating body with a strong force, and is moved to the cutting edge of the cutter to be surely cut. It is sent out to the rear, and at the same time it is released from the pinched state. At that time, since the structure is simple, with two support pipes extending above the rotating body being used as means for pressing the rotating body, the weeds etc. after being cut will pass between the two supporting pipes. It passes through and is expelled backwards without getting tangled with the rotating shaft in the support pipe or with anything else.

じないようにすることが望ましい。Next, to describe the structure of the rotating bodies (71) and (72), the base bodies (73) and (74) have a flange-like protrusion (73a) in the middle,
(74a), and a donut-shaped elastic body (76) such as rubber or thermoplastic elastomer having an outer diameter larger than the diameter of the brim-like protrusion.
The base body (
73) and (74). In order to prevent the donut-shaped elastic body (76) from slipping between the base bodies (73) and (74), the stop pin (77) is attached to the donut-shaped elastic body (76), (76) and the flange-shaped projection ( 73a), (7
4a). (79) is a temporary expression. The rotating bodies (71) and (72) configured in this way
) are provided with upper and lower donut-shaped elastic bodies (76), (
A recess is formed between the cutter storage spaces (76) and the cutter storage spaces (71a) and (72a). Here, since the cutter storage space (71a) is a recess that stores the main part of the cutter as described later, the flange-like protrusion (73a)
By making the diameter of the cutter storage space (71a) smaller than that of the brim-like protrusion (74a), the cutter storage space (71a) becomes the cutter storage space (74a).
72a). The reason why the donut-shaped elastic body (76) is chamfered into a truncated cone shape is to make it easier for the object to be cut to be caught in the lower part of the rotating body and to be easily removed backwards at the upper part. In addition, there are recesses (73b) in the upper parts of the base bodies (73) and (74).
(74b) is provided, and the lower end of the support pipe Qυ (Company) is inserted to prevent objects to be cut, such as weeds, from becoming entangled with the rotating shafts @II and @B. Although the diameters of the rotating bodies (71) and (72) do not necessarily have to be the same, by adjusting the gear ratio of the reduction gear mechanism so that the outer peripheral speeds of both rotating bodies match, it is possible to prevent strain on the pressure contact surface. It is desirable to prevent this from occurring.

へ出て行く。As mentioned above, when the rotating bodies (71) and (72) are pressed, the outer circumferential portion is an elastic body (76), so a contact surface is always formed even while the rotating bodies (71) and (72) rotate oppositely. Then, there is a recess formed on the outer peripheral surface, that is, a cutter storage space (
71a) and (72a) are arranged so as to be continuous with each other at the contact surface, so in the end, at the contact portion of both rotating bodies, a continuous cutter storage space is created between the upper contact surface (83) and the lower contact surface. (84) is sandwiched between the two. The cutter (81) is inserted into the continuous cutter storage space formed in this way, and the main part of the cutter (81) is inserted into the cutter storage space (71a) of the rotating body (71), so that the cutting edge (81a) The upper and lower parts are arranged so as to cross the contact surface, considering the upper and lower parts as one body.
It is fixed to the attachment part of the support (82). The curved cutter blade edge (81a) crosses the contact surface and enters the cutter storage space (72a) of the rotating body (72), and the rear part of the blade draws a smooth curve and exits the rotating body (72). get out.

なくスムーズに排除される。Since it is configured as described above, it has handles αυ and (turn) attached to the top of the main body case (11),
When the contact parts of the rotating bodies (71) and (72) that rotate oppositely are pressed against an object to be cut, such as weeds, the weeds, etc. are immediately caught up in the contact surfaces of both rotating bodies, and are held in place by the cutting edge of the cutter ( 81a>, the cutter is reliably cut, and then sent out backwards. At this time, the cutter (81) is moved from the rotary body (71) that houses the main part of the cutter to the other rotary body (72). However, since the cutting edge is curved and only shallowly penetrates the rotating body (72), weeds and the like can be smoothly removed without getting tangled with the cutting edge.
本発明の切断機構から明らかなように、回転体の回転速

高速まで任意に選びうるが、作業能率の上からは、毎分
100回転程度以上が好適である。As is clear from the cutting mechanism of the present invention, there is no particular limit to the rotational speed of the rotating body, and it can be arbitrarily selected from low to high speed according to the user's preference. A degree of rotation or more is preferable.

り出し能力を一層高めることが可能である。Further, in the contact portion of the rotating bodies (71) and (72), the upper contact surface (83) not only holds the object to be cut, but also has the role of sending out the cut piece after cutting to the rear. In this embodiment, it has the same size as the lower contact surface (84), but if the upper parts of both rotating bodies are made larger in the height direction so that the upper contact surface (83) becomes larger, it is possible to It is possible to further increase the delivery capacity of

のみを図示する)。FIG. 6 shows a second embodiment. A conventionally known brush cutter generally has a rotary blade at the tip of a pipe with a built-in rotary shaft, an engine or motor at the rear end, and an operating handle at the middle rear part. The shoulder rest has a structure in which a belt or the like is attached.The worker operates the handle while suspending the machine with the belt to cut the weeds in front of the machine.
A case in which the present invention is applied to such a system is shown (only the tip portion is shown).

刈り取りが行われる。The two support pipes are curved at the portions close to the rotating body, and are bundled together by a fixture (to) to form one piece. As in the first embodiment, the zero-rotation shaft to which the rotating body, cutter, drive source, etc. are attached is not shown, but a flexible shaft is used, and the other parts are the same as the above-mentioned brush cutter. In the embodiment, weeds and the like are cut while the tip is swung left and right (that is, in the direction perpendicular to the plane of the paper in the figure).

動する場合よりも格段に切断能力が向上する。(Effects of the Invention) As described above, the present invention has a structure in which the cutting edge of the cutter is housed inside the rotating body. There is no risk of hurting your feet when you mow the grass, and of course, there is no fear of debris hitting your eyes if they hit hard stones. In addition, since driving force is applied to both rotating bodies by two rotating shafts supported by two support pipes, the object to be cut, such as weeds, is drawn in with strong force, and only one is driven. The cutting ability is much improved compared to the case where the

し拘束しつつ切断する機構であるから、回転体の回転速
度は低くて良く、従って取り扱い上安全であるばかりか
、駆動源のパワーも比較的小さくて済み小型化が容易で
ある。Since this is a mechanism in which the outer peripheral side wall surface of the rotating body clamps and restrains the top and bottom of the cutting part of the workpiece while cutting, the rotational speed of the rotating body can be low, and therefore it is not only safe to handle, but also allows the drive source to It also requires relatively little power and is easy to downsize.

であると共に常に鋭い切れ味を保つことができる。Since the rotating bodies rotate elastically in contact with each other and are not in contact with the cutter, there is no friction at all in the cutting section, so there is no friction noise that tends to occur with clipper-type pruning machines, etc., and it is extremely quiet. Furthermore, since the cutter can be easily removed from the cutter support and replaced, it is convenient to handle and can always maintain sharpness.
