摘要： PROBLEM TO BE SOLVED: To improve the construction and operation of a portable drain pipe cleaning device. SOLUTION: A first clutch actuator 88 is supported relatively rotatably with a shaft 52 and displaceably in an axial line direction together with the shaft and is driven via a transmission pulley and a belt drive by a motor 110. A second clutch actuator 136 is supported coaxially with the first actuator, isolatedly therefrom and relatively rotatably. A clutch 138 is arranged between the two actuators and is shrunk radially and is engaged with a snake for cleaning a drain pipe in response with the displacement of the first actuator toward the second actuator. The clutch 138 and the second actuator 136 are arranged in a shroud 18 at one end of a housing. The position of the second actuator with respect to the first actuator is adjustable in the axial line direction.

摘要： PROBLEM TO BE SOLVED: To achieve labor-saving of scavenging work for a side groove formed on the peripheral edge part of a plantation. SOLUTION: A lower frame 1 which is substantially portal in front view is laid down on a pair of right and left running parts 2, 2. the right and left running parts 2, 2 are connected to each other, and an upper frame 12 is placed on the lower frame 1 in such a manner as to be freely elevated through an elevating mechanism 11. The middle part of a scrape-up conveyer 30 for discharging a water grass and sediment in the side groove to the outside of the side groove is fitted to the upper frame 12, and the scrape-up conveyer 30 is disposed in a space formed between a set of the right and left running parts 2, 2 and the lower frame 1.

摘要： PURPOSE: To provide a device for completely recovering and removing foreign matter sticking to the interior of a pipe while scraping the foreign matter. CONSTITUTION: A support member 10 is fixed to the main body 2 of a traveling frame 1 moving inside a pipe 30. In addition, a head 12 for removing foreign matter sticking to the inner wall of the pipe 30 is attached to the tip of an arm 11 which is freely expandable in an orthogonal direction with the shaft core of a rotatary shaft 4 for the support member 10 and is pressed against the inner wall surface 31 of the pipe 30 with a specified pressing force. Further, a cylindrical recovery duct 16 interlocked with the arm 11 and freely expandable is arranged in the arm 11. On the other hand, the support member 10 communicating with the recovery duct 16 is connected to a discharge duct 17 behind a guide hole formed on the rotating shaft 4. Thus, it is possible to prevent the water being fouled by the scraped foreign matter or sludge to the maximum allowable extent. Besides, it is possible to maintain a strict observation of the operation and, at the same time, prevent the foreign matter from being insufficiently scraped off. In addition, the foreign matter is totally recovered to an outside recovery device, so that it is so longer almost entirely flown into the ocean and the river. Thus, the problem of an environmental pollution in the ocean and the river can be solved and the operating efficiency can be enhanced.

摘要： PURPOSE: To provide a small-sized piping washing device capable of being smoothly revolved in piping, having durability and capable of cutting wood or the like penetrating into the piping. CONSTITUTION: A tubular part 5 is formed to the main body 4 fixed to the leading end of a hose 2 and a rotor 6 is fitted and held to the tubular part 5 in a rotatable manner in such a state that rollers 7, 7a are arranged on both sides of the rotor 6. The rotor 6 has a rear part 6a and a front part 6b and the rear part 6a is formed so as to have a large diameter and a revolving jet orifice 22 is opened to the rear part 6a in the direction reverse to the front part 6b and the front part 6b is gradually contracted so as to continue to the rear part 6a to be formed into a tapered shape and a roller 14 is supported at the leading end part thereof in a freely rotatable manner and, further, an advance jet orifice 18 is opened toward the hose 2 of the rear of the main body 4.
