FIG.

  1 to 3, reference numeral 1 denotes a dust collector for a grain preparation machine. The grain preparation machine is, for example, a grain dryer. The dust collector 1 for a grain preparation machine is composed of an air guide section 2 provided in the upper stage and a dust collecting water storage tank 3 provided in the lower stage. The upper air guide section 2 draws exhaust air from the grain preparation machine. An air passage 4 that is introduced and flows toward the dust collecting water tank is formed, and a water film forming plate (circular or circular) is formed in the air passage 4 so as to partially block the dust collecting water tank 3. (Square) 5 is provided horizontally, and the water injection nozzle 6 is closely opposed to the water film forming plate 5, and the water pumped up from the dust collecting water storage tank 3 arranged at the lower stage is injected from the water injection nozzle 6. Thus, a water film forming structure for blocking the dust collecting water tank 3 is formed. The dust collecting water tank 3 is provided with a carriage 7 at the bottom thereof, and has a movable structure that is inserted into and mounted on the upper air guide section 2 and can be drawn out and moved. 8 is an air exhaust port, 9 is an internal pressure adjusting port, and includes a dust removal filter. A flexible drooping air passage 10 is attached to the lower end of the air passage 4 opening toward the dust collecting water storage tank 3 of the air guide portion 2 to form a downward air passage extension portion 11. Reference numeral 12 denotes an introduction duct, which is connected to a wind outlet of a grain preparation machine such as a grain dryer or a dust outlet of a dust collector through the duct.

  The dust collecting water tank 3 is provided with a moving wheel 13 on the carriage 7 and is movable, and a hand handle 14 is provided on one end side to form a hand moving structure. A submersible pump 15 is mounted in the dust collecting water tank 3 close to the hand handle 14, and the submersible pump 15 and the water injection nozzle 6 are connected by a relay hose 16. A relay hose 16 is detachably attached to the connection port 17 via a coupler 18. In addition, a water supply hose 19 is connected to the dust collecting water tank 3 to supply water, and the water supply hose 19 is detachably connected to a connection port 20 of the water supply hose 19 via a coupler 21. The connection port 17 of the relay hose 16 and the connection port 20 of the water supply hose 19 are provided on the hand handle 14 side, and both the relay hose 16 and the water supply hose 19 can be attached and detached on the hand handle 14 side. The connection port 20 of the water supply hose 19 is provided with a floating automatic open / close valve 22.

The dust collecting water tank 3 is inserted under the air guide portion 2 as shown in FIG. 4A while grasping and moving the hand handle 14 as described above, but the front end portion of the carriage 7 is the front guide frame 25. The dust collecting water storage tank 3 stops at a fixed position with respect to the air guide part 2 as the rear end part is inserted following the guide plate 31. Further, the lock claw 23 is locked to the support column 24 of the air guide portion 2 and the tip end portion is pressed by the guide frame 25 and is finally mounted in a fixed state as shown in FIG.
As shown in FIG. 4B, when the lock release lever 26 of the lock claw 23 is pulled forward, the locked state is released, so that the dust collecting water storage tank 3 can be pulled out from the air guide section 2.

  In order to use the dust collector 1 for a grain preparation machine, a water supply hose 19 is connected to the connection port 20 of the dust storage tank 1 to supply water and store it to a predetermined water level. Then, the submersible pump 15 is driven so that the water in the dust collection storage tank 3 is sprayed from the water injection nozzle 6 to the upper surface of the water film forming plate 5 through the relay hose 16 and is connected to the dust collection reservoir 3. The state is to be blocked by a water film. The water in the dust collecting water tank 3 is circulated by the submersible pump 15 and used repeatedly.

  In this way, when the exhaust air from the grain preparation machine is introduced into the introduction duct 12 into the air guide section 2, dust mixed in the exhaust air is separated by the stirring and mixing action with the water film, It falls and accumulates in the dust collecting water tank 3 together with the water to be formed.

  For this reason, depending on the amount of accumulated dust even after the work is completed or at the appropriate time during the work, the dust in the dust collecting water storage tank 3 must be removed. In that case, as shown in FIG. The relay hose 16 is removed from the connection port 17 and hung on the hand handle 14, and the water supply hose 19 is also removed from the connection port 20. In the dust collector 1 for a grain preparation machine according to the present invention, the submersible pump 15 is mounted close to the hand handle 14 side of the dust collecting water tank 3, and the connection port 17 of the relay hose 16 is on the hand handle 14 side. Since the connection port 20 of the water supply hose 19 is also provided on the hand push handle 14 side, the relay hose 16 and the water supply hose 19 can be removed and connected to each other conveniently as a manual operation.

  When the relay hose 16 and the water supply hose 19 are removed, the dust collecting water tank 3 can be pulled out and moved from the air guide portion 2 as shown in FIG. 5 (B), so the dust collecting water tank 3 is moved to an appropriate place. In order to drain the water remaining in the dust collecting water tank 3, the relay hose 16 is lowered as shown in FIG. 6, or the drainage hose 27 is connected to the drain hose 27 as necessary, and the submersible pump 15 is driven. Drain the water. Then, the dust accumulated in the dust collecting water tank 3 is removed by scooping or scraping with a flat shovel at the tip. After the dust is removed, the dust collecting water tank 3 is moved to the wind guide portion 2 and inserted, and the relay hose 16 is connected to the connection port 17 and the water supply hose 19 is connected to the connection port 20.

  In addition, if the connection port 20 of the water supply hose 19 is provided in the air guide part 2 and water is supplied from the air guide part 2 to the dust collecting water tank 3 by water injection, the water supply hose is moved when the dust collecting water tank 3 is moved. Although it is not necessary to remove 19, illustration of this configuration is omitted.

  In the embodiment shown in FIGS. 7 and 8, the cart 7 of the dust collecting water tank 3 is provided with an inclination operation structure in which the tip end side is tilted high starting from the handwheel 14 side. That is, when the pedal 28 is stepped on by the push-up roller 30 interlocked by the push rod 29 to the pedal 28 provided on the hand pushing handle 14 side of the dust collecting water storage tank 3, the state shown in FIG. Since the tip end side of the dust collecting water tank 3 is pushed up and tilted toward the handwheel handle 14, the remaining water can be concentrated on the submersible pump 15 side when draining from the dust collecting water tank 3, and drainage can be performed more completely. It is convenient for subsequent dust removal.
