And a duct 5 that bypasses the shaft 4 and communicates with the suction port 1 is installed inside the rear side, and a casing 8 is supported on the vehicle body by columns 6 and 7. ing. Hereinafter, these will be described in detail.

  The casing 8 includes a motor with a reduction gear (not shown) whose rotational speed is variable by a speed controller. The casing 8 includes a sprocket 11 that is rotationally driven by the motor and one of a pair of sprockets 12 that are fixed to the shaft 3. A chain 13 is spanned between them, and a chain 15 is spanned between the other of the pair of sprockets 12 and a sprocket 14 fixed to the shaft 4. The shafts 3 and 4 are driven to rotate in conjunction with each other by a motor.

  Three blades 17 are attached to the shaft 3 at equal intervals in the circumferential direction, and the sediment sucked in from the suction port 1 by the rotation is scraped back and sent out.

  As shown in FIGS. 2 and 3, the shaft 4 includes axles 19 a and 19 b that are divided into approximately equal lengths, and cylindrical shafts 21 a and 21 b that are externally fitted to the axles 19 a and 19 b and that are divided into longer and shorter parts. The long cylindrical shaft 21a is integral with the one axle 19a and the key 22 in the rotational direction and is slidable in the axial direction. One end of the cylindrical shaft 21a has a pulley-like shape. The connecting tool 23 is fixed, and the cylinder shaft 21a slides in the left-right direction of the drawing in the left-right direction of the figure by the tilting operation of the clutch lever 24 fitted and locked to the connecting tool 23 in the left-right direction of the drawing. ing. On the other end of the cylindrical shaft 21a, recesses 28 into which pins 26 and protrusions 27, which will be described later, are fitted, are formed at even locations, for example, 2 or 4, at equal intervals in the circumferential direction.

  The other short cylinder shaft 21b is rotatable with respect to the other axle shaft 19b, and protrusions 27 are formed at equal intervals in one end at locations corresponding to the recesses 28, and the sprocket 14 is fixed to the other end. ing.

  Each of the axles 19a and 19b protruding from the vehicle body 2 is provided with a sprocket or a tire-like wheel 29, or a drive wheel 32 for driving the crawler 31 as shown in FIG. In FIG. 4, the pair of guide wheels 33 are connected by a rod 34 so as to swing around the drive wheel 32 in the left and right directions in the figure.

  The axle 19b is also provided with a pin 26 protruding in the diameter direction at a position where it does not interfere with the short cylinder shaft 21b when the short cylinder shaft 21b rotates. The pin 26 constitutes a clutch mechanism together with the protrusion 27 and the recess 28 described above.

  A damper 36 as shown in FIG. 5 is attached to the duct 5 at one end. The mounting position of the damper 36 can be adjusted in the vertical direction within the range of the long hole 37 by a set screw 35 fixed to the duct 5 through the long hole 37 of the duct 5, and the damper 35 is moved up and down. Accordingly, the inlet at one end of the duct is expanded or narrowed so that pressure adjustment at the one end, that is, suction force can be adjusted.

  The other end of the duct 5 protrudes from the rear surface of the vehicle body 2 and serves as a connection port 39 to which a vacuum car hose 38 (not shown) is detachably attached.

  The vehicle body 2 is also provided with a handle-like operation portion 41 that is chamfered with a corner at the lower end of the rear portion inclined or curved and protrudes in a rearwardly inclined manner at the rear portion of the vehicle body.

At the time of operation, the hose 38 of the vacuum car is connected to the connection port 39 and the position of the damper 36 is adjusted to adjust the suction force. As shown in FIG. 6, the protrusion 27 and the pin 35 are fitted into the recess 28, whereby the clutch is engaged and the four axles 19a and 19b and the cylinder shafts 21a and 21b are integrally connected in the rotation direction. In this state, a motor start switch (not shown) is pressed to start the motor. Accordingly, the shaft 3 is rotationally driven to rotate the blade 17, and the shaft 4 is rotationally driven to rotate the wheel 29. Then, the deposit sucked from the suction port 1 is scraped by the rotation of the former wing 27 and sent out to the duct entrance at the rear, and is carried out from the duct 5 and the hose 38, and the vehicle body 2 is caused to travel by the rotation of the latter wheel 29. It has become.

  With this device, the sediment is sucked and carried out while the front end of the vehicle body is landed, but when climbing over obstacles such as steps or the height of the deposit is high, it is difficult to scratch from the root. In some cases, the operation unit 41 is pushed down to incline the vehicle body 2 upward and the suction port 1 is lifted to get over obstacles such as steps, or the suction port 1 is placed in the middle of the deposit 43 as shown in FIG. The part is bitten and the deposit above is scooped out and sucked out.

  When the vehicle body 2 is reversed, the clutch lever 24 is switched as shown in FIG. 3 so that one of the cylinder shafts 21a is retracted in the right direction in the figure, and the recess 28 is detached from the protrusion 27 and the pin 26 (FIG. 8). . Thereby, even if the other cylinder shaft 21b is rotationally driven by the motor, the one cylinder shaft 21a and the axles 19a and 19b do not rotate in conjunction with each other, and the left and right wheels 29 are stopped. If the vehicle body 2 is to be reversed in this state, the vehicle body 2 can turn around the wheel 29 while rotating the other wheel 29 while the one wheel 29 is stopped. become able to. When the clutch lever 24 is switched as shown in FIG. 3, the wheels 29 are not rotated by the motor, but the vehicle body 2 can be pushed by the push operation of the operation unit 41. In this case, the vehicle body 2 is not a self-propelled vehicle but a handcart.

  At the time of the above-mentioned work, the vehicle body is self-propelled or is pushed and moved like a wheelbarrow, but remote control is also possible, and it is desirable to perform work underwater by remote control. In addition, when working in water, it is necessary to make a motor and other required parts have a watertight structure, and in order not to corrode, it is necessary to form a portion immersed in water with a corrosion resistant material such as stainless steel.

  It is also desirable that the device be fitted with a light so that it can be operated at night.

  In the above-described suction and carry-out device, when a worker is attached at the time of work, the worker moves while walking, but it is also possible to allow a worker to board the device.

  FIG. 9 shows an example thereof. An annular mounting portion 44 with a caster 43 fitted into the hose 38 from the hose end, a seat 45 projecting on the mounting portion 44, and both ends of the mounting portion 44 The vehicle body 2 includes rods 46 that are tiltably connected to each other by eyebolts. The vehicle body 2 is provided with a cover 47 that covers the wheels 29, and an operator sits on the seat 45 and hangs her legs on the cover 47. It is made to be able to. The mounting portion 44 described above may have a saddle shape so as to cover the hose 38 from above.

10 and 11 show another example of the suction / conveyance device. In the suction / conveyance device shown in FIG. 1, the auxiliary suction port 51 can be attached to the hood-like suction port 1 so that the suction port can be expanded. In other words, a recess 52 is formed in the rear part of the vehicle body 2 so that the wheels 29 are integrated into one without being arranged on both sides of the vehicle body 2 and are arranged in the recess 52 to form a unicycle structure. The structure is basically the same as that of the suction / unloading device shown in FIG. 1 except that the shaft 53 is not a shaft structure but is a single-structure shaft 53 and is supported and attached to the vehicle body 2 in a cantilevered manner. .
The suction and carry-out device of the present embodiment has a simpler structure than the suction and carry-out device shown in FIG. 1 because the suction port is widened and the shaft 53 is not a single shaft and has a double shaft structure.
