Abstract

PURPOSE:To obtain the subject apparatus capable of constantly keeping high propulsion efficiency corresponding to the amount of reaped algae loaded on the boat by attaching an algae-reaping apparatus to the front part of the boat to reap algae grown in water and providing the boat with a boat-propelling apparatus in a state freely movable in vertical direction. CONSTITUTION:Algae grown in water is reaped with an algae-reaping apparatus 2 attached to the front part of an algae-reaping boat 1. Paddle wheels 3a constituting a propelling apparatus 3 for the boat are placed at the front and rear parts of both sides of the boat 1. The shaft 24 of the propelling apparatus 3 is supported with a supporting member 25, which is inserted and fixed to a frame 26 to guide the supporting member in a state freely movable in vertical direction. The algae reaped with the algae reaper 2 placed in front of the boat 1 is hoisted with a hoisting conveyor 7 and loaded on the boat. The propelling apparatus 3 is lifted according to the increase of the draft of the boat 1 caused by the loaded algae to constantly keep high propulsion efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is applied to a work boat for mowing algae, which cuts algae growing in the water using a mower installed at the front of the hull.

(c) Problems to be Solved by the Invention Such algae-cutting work vessels require a propulsion device to propel them, but the present invention is particularly effective in reducing the amount of algae cut and loaded on water. It was created with the aim of constantly improving the propulsion efficiency of the propulsion device depending on the condition of the cargo.

(d) Means for solving the problem Therefore, 1. In order to always improve the propulsion efficiency of an algae-cutting work boat, the present invention removes algae that grows in the water using an algae-cutting machine installed at the front of the hull. In the work boat for mowing algae, the propulsion device for propelling the work boat was made vertically adjustable.

(f) Function With this construction, the algae that grows in the water as the work boat is propelled is cut off by the algae cutter, and the cut algae is loaded onto the hull.

As the amount of cargo loaded increases, the hull will gradually sink below the water surface, and the propulsion device attached to the hull will become deeper from the water surface, so if the propulsion device becomes deeper, the water surface of this propulsion device will increase. As the depth increases, the propulsion device is moved up and adjusted to the most appropriate position to improve propulsion efficiency, and when the hull rises and the propulsion device is not at the proper depth or position, this propulsion device is moved upward. Adjust the device downward to improve propulsion efficiency.

Fig. 8 shows a state in which the iron wheel (3b) is attached to the support body (25) with the mounting bolts (29), and the downward movement of the piston rod (28) causes the iron wheel (3b) to move as shown by the imaginary line. By protruding iron wheels (3b) from the bottom of the ship, the ship can be moved on land using the iron wheels (3b), and the
As shown in Figure 9, there is a water wheel (3) outside this iron wheel (3b).
When a) is tightened with the bolt (30)... it becomes a propulsion device (3) on water, and the water wheel (3a) is shown by the arrow (a).

The rotation of 7) causes the movable blades (ab) (5b) to reciprocate, thereby raising and lowering the lifting conveyor (7) and rear conveyor (+2b) respectively.

Therefore, the work boat is in the state shown in Figure 1 with the propulsion system (
3) While moving forward, the algae cutter (2) cuts the algae in the water, places the cut algae on the lifting conveyor (7), and falls onto the front conveyor (12a). Instead of transporting it backwards, it is loaded. At that time, when transferring to another carrier, the rear conveyor (+2b) is dropped into the carrier as shown by the imaginary line (b). Also, the degree to which the ship sinks depends on the amount of cargo loaded, so in that case, the propulsion device (3)... is adjusted up and down to bring it to an appropriate position above the water surface (L) to improve propulsion efficiency.

Further, the vertical adjustment of the propulsion device (3) is more convenient if a sensor is installed so that the vertical adjustment is automatically performed based on the water surface (L).

When moving on land, replace the water wheel (3a) with iron wheels (
3b) to protrude from the bottom of the ship as shown by the imaginary line (c), and at the same time bring the lifting conveyor (7) into the state shown by the imaginary line (d).

In addition, when transporting on a truck, the water wheel (3a) is removed to narrow the overall width of the work boat to facilitate loading.

In addition, as shown in FIG. 15, a chopper (49) with a guide plate (48) is installed near the end of the lifting conveyor (7).
As shown in Fig. 16, a compression roller (50) is installed opposite to the upper side of the terminal end, and a presser guide plate (50) is installed in front of this compression roller (50). 51)
If the amount of algae loaded is increased by adding a configuration such as forming a compression passage (52) formed by the above, the throughput will be increased.

(G) Effects of the Invention As is clear from the above description, the present invention provides an algae-cutting work boat that cuts algae that grows in the water with an algae cutter installed at the front of the hull, and is used to propel the work boat. Since the propulsion device is adjustable in vertical movement, it is possible to adjust the propulsion device to an appropriate position above the water surface depending on the condition of the cargo, such as the amount of algae that has been harvested and loaded. It has the advantage of being able to maintain good propulsion efficiency at all times, controlling the propulsion force by adjusting the propulsion device up and down, and being able to operate even in shallow water.
