昭６−6438、実公昭33−7970）。[Detailed description of the invention] A. Purpose of the invention The invention relates to an algae removal device for an algae cutter. Algae cutting boats are used to cut down algae growing in rivers, etc.
The algae cutter installed on this ship cuts algae by rotating a rotary blade plate horizontally as the ship advances. At this time, it is necessary to prevent algae floating from the front from becoming entangled with the algae cutter itself. For this reason, various algae removal devices have been devised (for example, Utility Model Publication No. 6438, 1983, and Utility Model Publication No. 33-7970).

It is rotatably supported by a support frame 3. 8 is frame 2
The transmission wheel is rotatably supported at a fixed position, and its rotation is transmitted to the shaft 7 via a bevel gear mechanism 9.
The shaft 7 can also be raised and lowered with respect to the mechanism 9. 1
0 is a transmission wheel attached to the shaft 7, and 11 is a rotating member that is rotatably supported on a vertical plane at a fixed position above the front part of the support frame 3. In the embodiment, a disc is used. , crankshaft, etc. may also be used.
This rotating member 11 is a transmission band 1 such as a chain or a V-belt suspended between the transmission wheel 10 and the rotating member 11.

It is connected to the upper end of the removal rod 14 at a point R so as to be able to swing back and forth on a vertical plane. If the link 13 and the algae removal rod 14 are arranged in a straight line when the eccentric point P reaches the highest point S, the point R can be swung back and forth across the straight line SQ, which is convenient for removing algae. However, if point R cannot be expected to move forward beyond straight line SQ due to water pressure, algae resistance, etc., move link 13 and algae so that point R is always ahead of straight line SQ (to the right of the drawing). The length of the removal rod 14 may be determined. In the drawings, 20 is a prime mover, 21 is a transmission mechanism, and 22 is a propulsion device.

刃板６の下方へ送り出す。 When the prime mover 20 is driven, the propulsion device 22 is operated via the transmission mechanism 21, and the ship 1 moves forward (to the right in the drawing). The rotation of this prime mover 20 is simultaneously caused by the shaft 7
As before, the rotary blade plate 6 rotates to cut algae. The movement of the shaft 7 is simultaneously transmitted to the rotating member 1 via the transmission wheel 10 and the transmission band 12.
1 and gives constant motion to the link 13. For this reason, the algae removal rod 14 swings back and forth, and when it swings forward, the algae that flows and touches the algae removal rod 14 is pushed downward, and when it tries to become entangled, it retreats and escapes from the algae, and the next The algae are further pushed downward by the forward movement of the rotary blade plate 6, and the same operation is repeated to finally send the algae to the lower side of the rotary blade plate 6.

果を奏する。C. Effect of the invention According to the invention, since it is constructed as described above, the algae floating from the front of the algae harvesting boat is swept to the bottom of the boat.
Therefore, it can be prevented from getting tangled with the algae cutter. In addition, this algae removal device has a small number of parts that are subject to water resistance, so it poses almost no obstacle to the forward movement of the ship, and has a simple and economical configuration, which provides various effects.
