Description

  The present invention relates to a water channel deposit removing apparatus that removes sediment such as earth and sand accumulated in a water channel.

Agricultural waterways are approximately 370,000 km nationwide, but with the aging of farmers and labor shortages, labor saving of waterway function maintenance work (deposit removal, etc.) is strongly demanded. Among agricultural watercourses, those with relatively large waterways and working passages can be used to remove sediments using machinery such as backhoes. There are many cases where it is difficult to bring in a mechanical device due to a field condition such as a narrow road.
On the other hand, as an apparatus for cleaning the side groove, an apparatus that collects sludge while cleaning the inside of the side groove using high-pressure water has been proposed (for example, see Patent Document 1).

Japanese Patent Laying-Open No. 2015-184221

  Here, assuming the case where the above-described gutter cleaning apparatus is used for removing sediments from agricultural waterways, the following problems arise. In other words, since the above-described cleaning apparatus uses high-pressure water for cleaning, extra water is added to sediment such as earth and sand, and the amount to be disposed increases. And in order to reduce such a disposal amount, since a dehydration volume reduction process is needed, an installation becomes heavy and cost will become high. Furthermore, it is necessary to work while mounting and moving a generator, a cleaning device, a tank, etc. on a cart with a power unit, but it is difficult to travel on the soft ground around the agricultural waterway with the wheels of the cart.

  This invention is made | formed in view of the said subject, The place made into the objective is to remove the deposit of a water channel efficiently irrespective of on-site conditions.

(Aspect of the Invention)
The following aspects of the present invention exemplify the configuration of the present invention, and will be described separately for easy understanding of various configurations of the present invention.

  The water channel deposit removing apparatus described in this section includes an injection mechanism, an ejector mechanism, a transport vehicle, a compressed air supply means, and a pipe. The injection mechanism is for injecting high-pressure fluid such as compressed air or high-pressure water to crush sediments such as earth and sand accumulated in the water channel. By adjusting the direction of the injection port and the injection pressure, Crush a wide range of sediments. The ejector mechanism sucks the sediment crushed by the injection mechanism using the compressed air supplied from the compressed air supply means. More specifically, the ejector mechanism has a compressed air flow inside the suction port. By generating a negative pressure, the deposit is sucked from the suction port. The transport vehicle is equipped with an injection mechanism and an ejector mechanism, and is used to move the injection mechanism and the ejector mechanism in the waterway during the approach path leading to the waterway and during the removal of deposits. The compressed air supply means is for supplying compressed air to the ejector mechanism, and is connected to the ejector mechanism via a supply hose. Further, the piping is used to pressure-feed the deposit sucked by the ejector mechanism using the compressed air supplied from the compressed air supply means to the ejector mechanism. That is, the piping is connected to the ejector mechanism, and the compressed air used to generate the negative pressure inside the suction port of the ejector mechanism is moved from the ejector mechanism into the piping together with the deposit sucked by the ejector mechanism. By flowing in, a deposit is conveyed by compressed air through piping.

  As described above, the channel sediment removal device described in this section performs the crushing operation of the sediment, which is included in the sediment removal operation, using the high-pressure fluid, and also performs the suction and conveyance of the sediment. Since both of the two operations are performed using compressed air, the manpower operation is greatly reduced. Furthermore, the compressed air supply means for supplying the compressed air via the supply hose may be installed at a position away from the water channel, and only a transport vehicle having a compact configuration equipped with an injection mechanism and an ejector mechanism is installed in the water channel. Just bring it in. Therefore, regardless of on-site conditions such as the width of the approach path to the water channel, the width of the water channel, and the presence or absence of a work channel, the transport vehicle is moved through the entrance channel and the water channel to efficiently remove sediment in the water channel. It becomes. In addition, the pumping of the sediment through the piping using compressed air also supports the transport of the sediment over a relatively long distance, so the length of the piping is adjusted to collect the removed sediment. The place is set at an arbitrary position such as the vicinity of the water channel or a position away from the water channel.

The compressed air supply means is connected not only to the ejector mechanism but also to the injection mechanism via a supply hose, and supplies compressed air to both the injection mechanism and the ejector mechanism. As a result, the three operations of crushing, suctioning, and conveying the deposits included in the deposit removal operation are all performed using compressed air, and the work by manpower is greatly reduced. Furthermore, since the injection mechanism, the ejector mechanism, and the piping all use compressed air supplied from the compressed air supply means, the entire apparatus is reduced in size and weight. Further, since water is not used for crushing the deposit, the weight of the deposit does not increase. For this reason, compared with the case where the deposit containing a water | moisture content is processed, while a conveyance operation | work etc. are performed efficiently, the further weight reduction of an apparatus will be achieved.

In the channel sediment removal apparatus described in this section, the drive assist mechanism provided in the transport vehicle is an air drive mechanism that uses compressed air supplied from the compressed air supply means as a power source. That is, as with the ejector mechanism, the drive assist mechanism of the transport vehicle uses the compressed air supplied from the compressed air supply means, so that the size of the apparatus can be increased compared to the case of using another power system. This suppresses the cost increase. Furthermore, since hydraulic pressure is not used as the power source of the transport vehicle, there is no adverse effect on the crops due to, for example, the oil leaking into the agricultural waterway.

In the channel sediment removal apparatus described in this section, the air drive mechanism of the transport vehicle includes a delivery unit that sends the compressed air to the ejector mechanism. Instead, it is sent to the ejector mechanism via the sending unit. Thereby, since the compressed air sent out from the air drive mechanism is reused to suck the deposits in the ejector mechanism, the energy is used more effectively.

(6) In the above items (1) to (5), a water channel deposit removing device in which a hood is attached around the suction port of the ejector mechanism (claim 6).
The channel sediment removal device described in this section has a hood attached around the suction port of the ejector mechanism, so that the inlet for sucking the deposit has a shape and size of the suction port of the ejector mechanism.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. Throughout the drawings, the same or corresponding parts are denoted by the same reference numerals.
FIG. 1 schematically shows a configuration of a water channel sediment removal apparatus 10 according to an embodiment of the present invention, and FIG. 2 shows a peripheral portion of a transport vehicle 20 included in the water channel sediment removal apparatus 10. ing. In the example of FIGS. 1 and 2, the water channel deposit removing device 10 includes an injection mechanism 12 and an ejector mechanism 14 mounted on the transport vehicle 20, and compressed air supply means connected to the transport vehicle 20 via a supply hose 32. 30 and a de-energizing cyclone mechanism 42 connected to the ejector mechanism 14 via a pipe 40.

  The injection mechanism 12 receives the compressed air supplied from the compressed air supply means 30 to the transport vehicle 20 via the supply hose 32 via the branch part 34, and injects the compressed air from the injection port 12a. The deposit S accumulated in G is crushed. For this reason, in consideration of the convenience of work, the injection mechanism 12 is transported so that the injection port 12a for injecting compressed air is arranged on the front side of the transport vehicle 20 (left side in FIG. 2A). It is mounted on the car 20. Further, the direction of the injection port 12a can be adjusted so as to face the bottom surface or the side surface of the water channel G, and the pressure of the compressed air injected from the injection port 12a can also be adjusted.

  The ejector mechanism 14 is for sucking the deposit S crushed by the injection mechanism 12, and the suction port 14 a for sucking the deposit S is provided in front of the transport vehicle 20, as with the injection mechanism 12. It is mounted on the transport vehicle 20 so as to be arranged on the side (left side in FIG. 2A). Further, the ejector mechanism 14 receives the compressed air supplied from the compressed air supply means 30 to the transport vehicle 20 via the supply hose 32 via the branch portion 34 and sucks the deposit S using the compressed air. To do. More specifically, the hose 36 branched into two from the supply hose 32 via the branch part 34 is connected to the ejector mechanism 14 as shown in FIG. 3, and each hose is shown by arrows A1 and A2. Compressed air is supplied to the ejector mechanism 14 through 36. The compressed air supplied through the hose 36 is jetted toward the diffuser 14b inside the ejector mechanism 14 as indicated by arrows A3 and A4.

Then, due to the flow of the compressed air, the range indicated by the symbol B including the inside of the suction port 14a becomes a vacuum state, and a negative pressure is generated there. Due to the negative pressure and the viscosity of the air, the surrounding air is drawn into the air jet flowing into the diffuser 14b, so that a suction force to the suction port 14a is generated as indicated by an arrow A5, and the deposit S is sucked together with the air. Is done. Then, the compressed air supplied through the hose 36, the air sucked from the suction port 14a, and the deposit S pass through the diffuser 14b and, as indicated by an arrow A6, the discharge port 14c of the ejector mechanism 14. From this, it flows into the pipe 40 connected to the ejector mechanism 14.
As shown in FIG. 2, a hood 16 is attached around the suction port 14a of the ejector mechanism 14 so as to open in a direction and size so as to facilitate the suction of the deposit S from the suction port 14a. . Further, for convenience of explanation, the portion covered with the hood 16 is shown to be transparent.

  Referring to FIGS. 1 and 2 again, the transport vehicle 20 equipped with the injection mechanism 12 and the ejector mechanism 14 is moved in the water channel G by the operator W when the deposit S is removed. As can be confirmed in 2 (b), the size is within the water channel G. The transport vehicle 20 includes a handle portion 22 and a drive assist mechanism 24, and the handle portion 22 is for the operator W to grip and steer the transport vehicle 20. The driving assist mechanism 24 generates a driving force for assisting movement when the worker W moves the transport vehicle 20. In the illustrated example, the driving power mechanism 24A uses an air driving mechanism 24A whose pneumatic power source is pneumatic. Has been.

  The air drive mechanism 24A receives the compressed air supplied from the compressed air supply means 30 to the transport vehicle 20 via the supply hose 32 via the branch portion 34, and generates a driving force by the compressed air. Further, the air drive mechanism 24A is provided with a delivery section 26 for delivering the compressed air used for generating the drive force to the ejector mechanism 14. The air driving mechanism 24A is generated by assisting forward and backward movement of the transport vehicle 20 by switching a switch (not shown), and by adjusting the amount of compressed air supplied through the branch portion 34. The driving force is adjusted. In addition, although the transport vehicle 20 travels with wheels in the illustrated example, it may travel with a crawler instead of the wheels.

  In the illustrated example, the compressed air supply means 30 is installed on a carriage 48 pulled by an agricultural machine (tractor) 46, and supplies the compressed air to the transport vehicle 20 via the supply hose 32. For the compressed air supply means 30, for example, a compressor is used. As described above, the compressed air supplied via the supply hose 32 is distributed to each of the injection mechanism 12, the ejector mechanism 14, and the air drive mechanism 24A via the branch portion 34 installed in the transport vehicle 20. Is done.

  Similar to the compressed air supply means 30, the de-energizing cyclone mechanism 42 installed on the carriage 48 pulled by the agricultural machine 46 is connected to the ejector mechanism 14 mounted on the transport vehicle 20 via the pipe 40. Yes. Then, the deposit S sucked by the ejector mechanism 14 is conveyed to the reduced-pressure cyclone mechanism 42 through the pipe 40 using the compressed air supplied to the ejector mechanism 14. More specifically, as described with reference to FIG. 3, the compressed air supplied to the ejector 14 via the hose 36, the air sucked from the suction port 14a, and the deposit S pass through the diffuser 14b. As indicated by an arrow A6, the air flows from the discharge port 14c of the ejector mechanism 14 to the pipe 40. As a result, the deposit S that has flowed into the pipe 40 is pumped through the pipe 40 by the compressed air that also flows into the pipe 40, and is transported to the reduced-pressure cyclone mechanism 42 connected to the outlet side of the pipe 40.

  The de-energizing cyclone mechanism 42 weakens the momentum of the deposit S and compressed air that have passed through the pipe 40 and separates the deposit S and air. That is, as shown in FIG. 4, the compressed air and the sediment S that have reached the depressing cyclone mechanism 42 in the flow as indicated by the arrow A7 flow spirally inside the depressing cyclone mechanism 42 having an inverted frustoconical shape. It is reduced by this. The air rising by the spiral flow is discharged from the upper part of the depressing cyclone mechanism 42 as indicated by an arrow A8, and the sediment S that flows downward by gravity while flowing spirally is indicated by an arrow A9. As described above, the lowering cyclone mechanism 42 is discharged from the lower part. As shown in FIG. 1, the deposit S thus separated is deposited and collected in the vicinity of the de-energizing cyclone mechanism 42.

  In the example of FIG. 1, the compressed air supply means 30 and the de-energizing cyclone mechanism 42 installed on the carriage 48 towed by the agricultural machine 46 are arranged at positions relatively close to the transport vehicle 20. The use form of such a positional relationship of the water channel sediment removing apparatus 10 according to the embodiment of the present invention is, for example, depositing the removed sediment S immediately next to the water channel G from which the sediment S is removed. Applies to cases. In addition, the channel sediment removal apparatus 10 according to the embodiment of the present invention performs the sediment S removal operation in a state where water flow to the channel G is blocked in principle.

  Next, FIG. 5 shows a usage pattern different from that of FIG. 1 of the water channel deposit removing apparatus 10 according to the embodiment of the present invention. That is, the water channel deposit removing device 10 of FIG. 5 is a utilization form in the case where the air supply means 30 and the depressurizing cyclone mechanism 42 are arranged at a position away from the transport vehicle 20. The piping 40 for pumping to the de-energizing cyclone mechanism 42 is laid longer than the example of FIG. In the example of FIG. 5, the pipe 40 is composed of a flexible pipe 40 </ b> A and a lightweight iron pipe 40 </ b> B, and is connected to a range portion connected to the transport vehicle 20 moving in the water channel G and to the reduced-pressure cyclone mechanism 42. The flexible tube 40A that can be bent is used for the range portion, and a plurality of lightweight iron tubes 40B are connected and used between the flexible tubes 40A. By adjusting the quantity of the plurality of lightweight iron pipes 40B, the length of the entire pipe 40 is adjusted.

  In addition, a simple detachable joint member is used at a connection portion 40C between the flexible tube 40A and the light iron tube 40B and a connection portion between the light iron tubes 40B. Thereby, for example, when the lightweight iron pipe 40B is added or removed in order to extend or shorten the pipe 40 according to the progress of the work, the reconnection work between the flexible pipe 40A and the lightweight iron pipe 40B, or between the lightweight iron pipes 40B. The reconnection operation is easily performed. In the example of FIG. 5, it is not necessary to arrange the air supply means 30 and the depressing cyclone mechanism 42 on the soft ground around the water channel G. It is installed on the platform of the small truck 50, not on the carriage 48 pulled by the vehicle. Further, the deposit S discharged from the de-energizing cyclone mechanism 42 is packed in a flexible container bag 52 and collected. The form as shown in FIG. 5 is used for decontamination work of the water channel G, for example. In FIG. 5, the supply hose 32 for supplying the compressed air from the compressed air supply means 30 to the transport vehicle 20 is not shown, but the supply hose 32 may be laid along the pipe 40. Good.

  Now, according to the embodiment of the present invention configured as described above, the following operational effects can be obtained. That is, the channel sediment removal apparatus 10 according to the embodiment of the present invention includes an injection mechanism 12, an ejector mechanism 14, a transport vehicle 20, a compressed air supply means 30, and a pipe 40, as shown in FIGS. Is included. The injection mechanism 12 is for injecting a high-pressure fluid such as compressed air or high-pressure water to crush sediment S such as earth and sand accumulated in the water channel G, and adjusting the direction of the injection port 12a and the injection pressure. By this, a wide range of deposits S in the water channel G can be crushed. The ejector mechanism 14 sucks the sediment S crushed by the injection mechanism 12 using compressed air supplied from the compressed air supply means 30, and more specifically, as shown in FIG. The deposit S is sucked from the suction port 14a by generating a negative pressure inside the suction port 14a by the flow of compressed air. The transport vehicle 20 has the injection mechanism 12 and the ejector mechanism 14 mounted thereon, and moves the injection mechanism 12 and the ejector mechanism 14 in the waterway G during the approach path leading to the waterway G and the removal of the deposit S. belongs to.

  The compressed air supply means 30 is for supplying compressed air to the ejector mechanism 14, and is connected to the ejector mechanism 14 via a supply hose 32. The compressed air supply means 30 can be easily transported by an agricultural machine 46 such as a tractor. The pipe 40 is configured to pump the deposit S sucked by the ejector mechanism 14 using the compressed air supplied from the compressed air supply means 30 to the ejector mechanism 14. That is, the piping 40 is connected to the ejector mechanism 14, and as shown in FIG. 3, compressed air used for generating a negative pressure inside the suction port 14 a of the ejector mechanism 14 is sucked by the ejector mechanism 14. By flowing into the pipe 40 from the ejector mechanism 14 together with the deposit S, the deposit S is conveyed by the compressed air through the pipe 40.

  As described above, the water channel deposit removing apparatus 10 according to the embodiment of the present invention performs the crushing operation of the deposit S included in the operation of removing the deposit S using the high-pressure fluid, Since the two operations of sucking and transporting the object S are both performed using compressed air, it is possible to greatly reduce the work by manpower. Further, the compressed air supply means 30 for supplying the compressed air via the supply hose 32 may be installed at a position away from the water channel G. In the water channel G, a compact mechanism in which the injection mechanism 12 and the ejector mechanism 14 are mounted. It is only necessary to bring in the configured transport vehicle 20. Therefore, regardless of the field conditions such as the width of the approach path to the water channel G, the width of the water channel G, and the presence or absence of a work channel, the transport vehicle 20 is moved in the approach channel or the water channel G, and the deposit S of the water channel G Can be efficiently removed. In addition, the pumping of the deposit S that passes through the pipe 40 using compressed air can also support the transport of the deposit S over a relatively long distance as shown in FIG. By doing so, the collection place of the removed deposit S can be set to an arbitrary position such as the vicinity of the water channel G or a position away from the water channel G.

  Further, in the water channel deposit removing apparatus 10 according to the embodiment of the present invention, the injection mechanism 12 injects compressed air supplied from the compressed air supply means 30 as a high-pressure fluid, and sediment deposited on the water channel G. The deposit S is crushed. For this reason, the compressed air supply means 30 is connected not only to the ejector mechanism 14 but also to the injection mechanism 12 via the supply hose 32, and supplies the compressed air to both the injection mechanism 12 and the ejector mechanism 14. As a result, the three operations of crushing, suctioning, and conveying the deposit S included in the deposit S removal operation can be performed using compressed air, greatly reducing human labor. it can. Furthermore, since the injection mechanism 12, the ejector mechanism 14, and the pipe 40 all use compressed air supplied from the compressed air supply means 30, the entire apparatus can be reduced in size and weight. Moreover, since water is not used for crushing the deposit S, the weight of the deposit S does not increase. For this reason, as compared with the case where the deposit S containing moisture is processed, it is possible to efficiently perform the transfer operation and the like, and to further reduce the weight of the apparatus.

  Moreover, the channel sediment removal apparatus 10 according to the embodiment of the present invention includes a handle portion 22 for the operator W to steer the transport vehicle 20 and a drive assist mechanism for assisting the operator W in transport. 24 is provided. Thereby, the operator W can steer by holding the handle portion 22 while receiving driving assistance from the driving assistance mechanism 24 and can easily move the transport vehicle 20 in the water channel G or the like. In the channel sediment removal apparatus 10 according to the embodiment of the present invention, the driving assist mechanism 24 provided in the transport vehicle 20 uses the compressed air supplied from the compressed air supply means 30 as a power source. It is what is. That is, as with the injection mechanism 12 and the ejector mechanism 14, the drive assist mechanism 24 of the transport vehicle 20 uses the compressed air supplied from the compressed air supply means 30 to compare with a case where another power system is used. Thus, the increase in size and cost of the apparatus can be suppressed. Furthermore, since hydraulic pressure is not used as the power source of the transport vehicle 20, for example, it is possible to prevent adverse effects on agricultural products caused by oil leaking into agricultural waterways.

In addition, the channel sediment removal apparatus 10 according to the embodiment of the present invention is used as a power source by the air drive mechanism 24A of the transport vehicle 20 including the delivery unit 26 that sends the compressed air to the ejector mechanism 14. The compressed air is released to the ejector mechanism 14 via the delivery unit 26 without being released into the atmosphere and becoming ineffective energy. Thereby, since the compressed air sent out from the air drive mechanism 24A can be reused for sucking the deposit S in the ejector mechanism 14, energy can be utilized more effectively.
Furthermore, the water channel deposit removing apparatus 10 according to the embodiment of the present invention has an inlet for sucking the deposit S by attaching the hood 16 around the suction port 14a of the ejector mechanism 14. The shape and size of the suction port 14 a of the ejector mechanism 14 can be expanded to the shape and size of the hood 16. Moreover, it is possible to prevent the deposit S from being scattered during the suction, and the deposit S being crushed in the vicinity of the hood 16 from being scattered.

The channel sediment removal apparatus 10 according to the embodiment of the present invention further includes a depressing cyclone mechanism 42, and this depressing cyclone mechanism 42 is provided on the outlet side of the piping 40 that pumps the deposit S. Connected. As a result, in the de-energizing cyclone mechanism 42, the momentum of the air energy used for pumping can be removed, and the deposit S that has passed through the pipe 40 can be separated from the air. Can be taken out efficiently. Further, as shown in FIG. 5, the de-energizing cyclone mechanism 42 may be installed at a position away from the water channel G in the state of being connected to the pipe 40 as in the case of the compressed air supply means 30. It is not necessary to install in the vicinity.
Furthermore, the water channel deposit removing apparatus 10 according to the embodiment of the present invention is configured such that the transport vehicle 20 on which the injection mechanism 12 and the ejector mechanism 14 are mounted is a crawler vehicle, so that it can be used on soft ground around agricultural water channels or earth and sand. Even in the water channel G in which etc. are accumulated, it becomes possible to travel easily. In addition, if a single crawler vehicle is employed, it is possible to promote downsizing suitable for movement in the approach path and water channel G.

  Here, in the channel sediment removal apparatus 10 according to the embodiment of the present invention, the channel G to be removed of the sediment S is not limited to a concrete side groove or the like, but is provided with a groove provided in soil with a backhoe or the like. It may be a digging side groove. Further, the drive source of the drive assist mechanism 24 of the transport vehicle 20 is not limited to the pneumatic type, and may be a small engine or an electric motor. Further, by adding a mechanism for adding a small amount of water in the vicinity of the injection port 12a of the injection mechanism 12, the injection mechanism 12 may be configured to inject an air-fuel mixture in which compressed air and water are mixed. In this case, the deposit S or the like firmly stuck to the concrete side groove or the like can be peeled off by using the mixed air jet from the injection mechanism 12.

  In addition, the channel sediment removal apparatus 10 which concerns on embodiment of this invention is not limited to the injection mechanism 12 which injects a high pressure fluid, Injecting compressed air, For example, even if it injects high pressure water Good. In this case, for example, high-pressure water supply means is installed on the carriage 48 or the small truck 50, and the high-pressure water supply means and the injection mechanism 12 are connected by a supply hose separate from the supply hose 32. That's fine. Thereby, the sediment S accumulated in the water channel G can be efficiently crushed and removed using high-pressure water in a state where water is stretched without blocking water flow to the water channel G. it can.

For this reason, in consideration of the convenience of work, the injection mechanism 12 is transported so that the injection port 12a for injecting compressed air is arranged on the front side of the transport vehicle 20 (left side in FIG. 2A). It is mounted on the car 20. Also, the orientation of the injection port 12a is adjustable so as to face the bottom surface or the side surface of the agricultural waterways G, also becomes adjustable pressure of the compressed air injected from the injection port 12a.

  The ejector mechanism 14 is for sucking the deposit S crushed by the injection mechanism 12, and the suction port 14 a for sucking the deposit S is provided in front of the transport vehicle 20, as with the injection mechanism 12. It is mounted on the transport vehicle 20 so as to be arranged on the side (left side in FIG. 2A). Further, the ejector mechanism 14 receives the compressed air supplied from the compressed air supply means 30 to the transport vehicle 20 via the supply hose 32 via the branch portion 34 and sucks the deposit S using the compressed air. To do. More specifically, the hose 36 branched into two from the supply hose 32 via the branch part 34 is connected to the ejector mechanism 14 as shown in FIG. 3, and each hose is shown by arrows A1 and A2. Compressed air is supplied to the ejector mechanism 14 through 36. The compressed air supplied through the hose 36 is jetted toward the diffuser 14b inside the ejector mechanism 14 as indicated by arrows A3 and A4.

Then, due to the flow of the compressed air, the range indicated by the symbol B including the inside of the suction port 14a becomes a vacuum state, and a negative pressure is generated there. Due to the negative pressure and the viscosity of the air, the surrounding air is drawn into the air jet flowing into the diffuser 14b, so that a suction force to the suction port 14a is generated as indicated by an arrow A5, and the deposit S is sucked together with the air.

Then, the compressed air supplied through the hose 36, the air sucked from the suction port 14a, and the deposit S pass through the diffuser 14b and, as indicated by an arrow A6, the discharge port 14c of the ejector mechanism 14. From this, it flows into the pipe 40 connected to the ejector mechanism 14.
As shown in FIG. 2, a hood 16 is attached around the suction port 14a of the ejector mechanism 14 so as to open in a direction and size so as to facilitate the suction of the deposit S from the suction port 14a. . Further, for convenience of explanation, the portion covered with the hood 16 is shown to be transparent.

Reference to Figures 1 and 2 again, the injection mechanism 12 and the truck 20 equipped with the ejector mechanism 14, upon removal work of deposits S, and intended to be moved in agricultural water channel G by the operator W as can be seen in FIG. 2 (b), it is sized to fit within the agricultural waterway G. The transport vehicle 20 includes a handle portion 22 and a drive assist mechanism 24, and the handle portion 22 is for the operator W to grip and steer the transport vehicle 20. The driving assist mechanism 24 generates a driving force for assisting movement when the worker W moves the transport vehicle 20. In the illustrated example, the driving power mechanism 24A uses an air driving mechanism 24A whose pneumatic power source is pneumatic. Has been.

  The air drive mechanism 24A receives the compressed air supplied from the compressed air supply means 30 to the transport vehicle 20 via the supply hose 32 via the branch portion 34, and generates a driving force by the compressed air. Further, the air drive mechanism 24A is provided with a delivery section 26 for delivering the compressed air used for generating the drive force to the ejector mechanism 14. The air driving mechanism 24A is generated by assisting forward and backward movement of the transport vehicle 20 by switching a switch (not shown), and by adjusting the amount of compressed air supplied through the branch portion 34. The driving force is adjusted. In addition, although the transport vehicle 20 travels with wheels in the illustrated example, it may travel with a crawler instead of the wheels.
