Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of an on-board spraying device which is used, for example, when it is placed on a bed of a vehicle or the like and sprays powdered particles such as an antifreezing agent onto a road or the like.

[0002]

[Prior art]

In the past, on-board type sprayers with a spraying capacity of 1 m ³ class generally have an open / close type for adjusting the amount of powder and granules in order to simplify the structure and achieve low cost. (See Japanese Utility Model Laid-Open No. 2-148029 and Japanese Patent Laid-Open No. 5-125707). However, such a product is apt to be clogged at the opening and closing part, and has a drawback that it cannot cope with crushed salt or sand.

[0003]

[Problems to be solved by the device]

 The present invention was devised in order to solve this problem in view of the above problems, and the purpose is to prevent clogging, and to mount crushed salt and sand. To provide a spraying device.

[0004]

[Means for Solving the Problems]

 Basically, the on-board spraying device of the present invention is provided on a stand that can be placed on a loading platform of a vehicle, a hopper that is provided on the stand for gravity-falling the accumulated granular material, and a hopper that is installed on the hopper. A chute that guides the powder and granules downwards, a metering rotor that is installed in the middle of the chute to deliver the powder and granules in specified amounts, a rotor motor that drives the metering rotor, and a swivel below the chute. It is characterized by the fact that it is composed of a sprayer that is provided to spray powder and granules and a spray motor that drives the sprayer.

[0005]

[Action]

 The on-board spraying device is mounted by mounting a stand on a bed or the like of a vehicle. The granular material stored in the hopper is gravity-dropped and sent to the chute. When the rotor motor is driven, the metering rotor is rotated and the granular material is delivered in a predetermined amount. When the spraying motor is driven, the spraying disc is swung and the particles from the chute are sprayed in the circumferential direction. Since the metering rotor is installed in the middle of the chute, it is possible to forcibly send out the granular material from the hopper in specified amounts, and there is no possibility of clogging at this part.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a mounting type spraying device according to an embodiment of the present invention. FIG. 2 is a rear view of FIG. FIG. 3 is a side view showing an enlarged main part of FIG. 1. FIG. 4 is a rear view of FIG. The on-board type spraying device 1 is mainly composed of a stand 2, a hopper 3, a chute 4, a metering rotor 5, a rotor motor 6, a spraying plate 7, and a spraying motor 8. The stand 2 is provided so that it can be placed on a cargo bed of a vehicle. In this example, the stand 2 has a four-frame box shape, and is placed on a truck cargo bed (not shown) except for a rear portion thereof, and is attached to a chain and a turn. It is adapted to be fixed by a fixture 9 composed of a buckle or the like. The hopper 3 is provided in the stand 2 and gravity lowers the stored powder and granules. In this example, it has a square pyramid shape with upper and lower entrances and exits, and the entrance into which the powder and granules are put is a lid. It is closed so as to be openable by means of 10, and the outlet is located at the rear portion and above the lower surface of the stand 2. The chute 4 is provided in the hopper 3 and guides the powder and granular material to the downward direction. It is attached and extends downward from the rear of the stand 2. The metering rotor 5 is provided in the middle of the chute 4 and sends out a predetermined amount of powder or granular material. In this example, the casing 11 formed in the middle of the chute 4 and the casing 11 are rotatable about the horizontal axis. And a rotor 12 provided in the. The rotor motor 6 drives the metering rotor 5. In this example, the rotor motor 6 is an electric motor, is provided on the right side of the chute 4, and is connected to rotate the rotor 12. The spreader 7 is provided below the chute 4 so as to be rotatable so as to spray the powder and granules. In this example, the support 13 is provided at the rear of the chute 4 and is rotatable about the vertical axis. And a swivel plate 14 provided on the. The spraying motor 8 drives the spraying disk 7. In this example, the spraying motor 8 is an electric motor and is provided above the support 13 and is connected to rotate the swivel plate 14. The rotor motor 6 and the spraying motor 8 are connected to a controller 16 provided on the driver's seat of the vehicle by a cable 15 and also connected to a battery mounted on the vehicle via a cigarette lighter unit to control the controller 16 The rotation speed is controlled according to the spraying condition. On the stand 2 on the front side of the spreader 7, a reflecting plate 17 for reflecting the powder particles is hung. Next, the operation will be described based on such a configuration. The on-board spraying device 1 is mounted by mounting the stand 2 on a bed or the like of a vehicle and fixing it by a fixture 9. The powdery particles are stored by being opened from the lid 10 of the hopper 3 and introduced from the inlet. The granular material stored in the hopper 3 is gravity-fallen and sent to the chute 4. When the rotor motor 6 is driven, the rotor 12 of the metering rotor 5 is rotated with respect to the casing 11 and the granular material is delivered by a predetermined amount. When the spraying motor 8 is driven, the swivel plate 14 of the spraying disk 7 is swung with respect to the support 13 and the powder particles from the chute 4 are sprayed in the circumferential direction. At this time, the powder particles scattered forward are reflected by the reflection plate 17. The rotation speeds of the rotor motor 6 and the spray motor 8 are controlled by the controller 16 from the driver's seat of the vehicle according to the spray situation. Since the metering rotor 5 is provided in the middle of the chute 4, it is possible to forcibly send out the granular material from the hopper 3 by a predetermined amount, and it is possible to prevent clogging at this portion. Therefore, the antifreezing agent will not be clogged when it becomes wet due to the water content in the air or because of the small stones in the sand when the sand is sprayed. When the on-board spraying device 1 is stored and stored after the spraying work is completed, the chute 4 is removed from the hopper 3 and the metering rotor 5, rotor motor 6, sprayer 7 and spraying motor 8 attached to the chute 4 are removed. It is located in the space on the front side of the stand 2 as shown by the chain line in FIG. At this time, since the outlet of the hopper 3 is located above the lower surface of the stand 2, it does not come into contact with the storage surface. In this way, the whole becomes compact and the storage space is small.

[0007]

[Effect of device]

 As described above, according to the present invention, the following excellent effects can be obtained. (1) It consists of a stand, hopper, chute, metering rotor, rotor motor, spreader, and spraying motor. Above all, a metering rotor that forcibly discharges powder and granules is provided in the middle of the chute. It can also prevent crushed salt and sand. (2) Since the metering rotor that forcibly discharges the powder and granules is provided in the middle of the chute, the powder and granules can be supplied to the spraying machine in a predetermined amount, and the spraying by this can be performed evenly. it can.
