It is possible to appropriately adjust the connection position of.

≪Configuration of spraying unit 3≫
Next, the spraying unit 3 that sprays the antifreezing agent M that naturally falls from the discharge / drop opening 2 of the hopper 1 by opening the shutter plate 200 of the shutter mechanism will be described.
The spraying unit 3 spreads the antifreezing agent M that naturally falls from the discharge drop port 2 of the hopper 1 in a wide angle toward the rear of the vehicle B that travels by the rotation of the rotating disk 4. Is mounted in a state of being supported by a support frame 300 attached to the apparatus machine frame 100 on the outside of the hopper 1 where the opening is opened.
The spreading unit 3 includes a rotating disk 4 including a blade member 5, an electric motor 6 that is a rotational drive source of the rotating disk 4, a spreading guard member 7 that is disposed along the outer periphery of the rotating disk 4, and an electric motor. The main components are a reversing box 8 in which 6 is installed, and a receiving port member 9 that guides the antifreezing agent M in the hopper 1 falling from the discharge dropping port 2 onto the rotating disk 4.

The output shaft 6 a that is vertically downward in the reversing box 8 is connected to the output transmission shaft 11 that is attached to the rotation axis P <b> 1 of the rotating disk 4 by the ring member 12 and the bolt nut 13 by the connecting tool 10. The rotating disk 4 is driven to rotate. The output transmission shaft 11 is rotatably attached to and supported at the bottom of the reversing box 8 by a cylindrical support member 15 having a bearing 16 on the inner axis.

≪Configuration of spray guard member 7≫
Next, a description will be given of the spray guard member 7 that covers the rotating disk 4 within a predetermined circumferential angle θ1 range described in detail later on the rotating disk 4 on the outer periphery of the disk in the rotating direction of the rotating disk 4.
As shown in FIGS. 4 and 5, the spreading guard member 7 is disposed on the rotating disk 4 that is discharged from the discharging and dropping port 2 of the hopper 1 and is located closer to the traveling direction of the vehicle B than the disk axis P <b> 1 of the rotating disk 4. When the antifreezing agent M that is naturally dropped through the receiving member 9 is discharged from the rotating disk 4 in cooperation with the rotation of the rotating disk 4 and the blade member 5, the spraying direction of the vehicle B traveling It becomes the rear and plays the role of regulating the spraying direction and the spraying width (spreading range) L of the antifreezing agent M so that the spraying width L becomes the lane width of the traveling lane. That is, the spray guard member 7 regulates the spray direction and the spray width L of the antifreezing agent M for realizing efficient and efficient spraying in cooperation with the blade member 5.

  As shown in FIGS. 2 to 5, the spreading guard member 7 has a length (arc length) corresponding to a semicircle of the rotating disk 4 using a strip-shaped plate material having a predetermined width (height). It is formed in a curved arc shape. As shown in FIGS. 2 and 3, the spreading guard member 7 is attached and supported via a top plate (fixed disk) 17 to the lower end of the support member 15 attached to the bottom of the reversing box 8. As shown in FIG. 5, the outer periphery of the disk in the rotation direction of the rotating disk 4 is provided so as to cover the range in the circumferential direction at a predetermined angle θ1.

  The top plate 17 for attaching and supporting the spreading guard member 7 is slightly larger than the diameter of the rotating disk 4 and is formed in a disk shape corresponding to the size (arc) of the spreading guard member 7. The lower end of the support member 15 is fixedly attached and supported by a ring member 18 and a bolt nut 19. The spreading guard member 7 is attached to the top plate 17 by welding or spotting.

≪Configuration of inversion box 8≫
The reversing box 8 in which the electric motor 6 is installed and supported by attaching and supporting the top plate 17 to the bottom via the support member 15 is composed of two members, a box main body portion 8a and a cover portion 8b. As shown in FIGS. 2 and 3, the box body 8 a is substantially in a vertical side view in which the upper side is bent and inclined backward (spreading direction) from an iron plate having a thickness that maintains appropriate rigidity (strength). It is a vertically long L-shape and is formed in a substantially U-shape opened rearward in a cross-sectional view. And the box main-body part 8a attaches and mounts the electric motor 6 on the motor installation board 20 with which it is equipped in the bottom part side downward, and is below the motor installation board 20, the output shaft 6a, the output transmission shaft 11, and Are coupled on the same axis by the coupling tool 10.

In such a configuration, the box body 8a is supported by the left and right horizontal frame members 302 provided on the both side frames 301 on the upper half side of the support frame 300 via the rotation support shaft 14, respectively. Thus, it is installed between the side frame portions 301 of the support frame 300 so as to be turned upside down. Cylindrical shaft support members 303 facing inward are attached to the horizontal frame members 302 on both sides, and the small diameter portions at both ends of the rotation support shaft 14 are rotatably inserted and supported on the shaft support member 303. I have to.
On the other hand, as shown in FIGS. 2 and 3, the cover portion 8 b is formed in a substantially inverted L shape that faces downward so as to cover the opening of the upper surface and the rear surface of the box main body portion 8 a. The main body 8a is detachably attached.

  In this embodiment, as shown in FIG. 6, a safety switch that cuts off the current to the electric motor 6 when the reversing box 8 is lifted upside down between the reversing box 8 and the support frame 300. 22 is provided.

The safety switch 22 includes a switch box 22a disposed on the support frame 300, and the switch box 22a includes a push button 23 that is urged outwardly by an internal spring material or the like. The safety switch 22 includes a button pressing ON / OFF switching member 22b disposed on the reversing box 8 side, and the electric motor 6 is energized while the push button 23 is pressed. It is configured such that the electric motor 6 is de-energized with the button push ON / OFF switching member 22b separated and the push button 23 restored to the external convex shape.
That is, as shown in FIG. 6 (a), when the reversing box 8 with the rotating disk 4 or the like positioned downward is in a reverse inverted state (when the antifreezing agent M is sprayed), a current is passed through the electric motor 6. As shown in FIG. 6B, the energization of the electric motor 6 is cut off when the reversing box 8 is turned upside down with the rotating disk 4 or the like positioned upward.

  Further, in this embodiment, as shown in FIGS. 2, 3, and 6, two types of attachments are attached in which the reversing box 8 is fixedly attached to the support frame body 300 when the reversing box 8 is in the lower reversing and returning state. Parts 24 and 25 are provided.

The attachment portion 24 is for temporarily fixing the reversing box 8 to the support frame 300 when the reversing box 8 is reversed upward and when it is reversed downward. It comprises a pin member 24a disposed at a predetermined position in the vertical direction and a hook member 24b disposed at a predetermined position on the reversing box 8 side and hooked on the pin member 24a.
On the other hand, the mounting portion 25 is for fixing the reverse box 8 to the support frame 300 in a state where the reverse box 8 is temporarily fixed to the support frame 300 by the mounting portion 24. The nut member 25a is disposed at a predetermined position in the vertical direction via a bracket 26, and the knob member 25b is screwed and fastened to the nut member 25a via a bracket 27 disposed at a predetermined position on the reversing box 8 side. .
Thereby, in a state where the reversal box 8 is fixedly attached to the lower reverse return position shown in FIG. 6A and the upper reverse position shown in FIG. And the maintenance of the discharge drop 2 of the hopper 1 after the movement to the spraying site or after the spraying is completed can be performed safely.

≪Configuration of receiving member 9≫
Next, a receiving member that receives the antifreezing agent M discharged and dropped from the discharging and dropping port 2 of the hopper 1 from the discharging and dropping port 2 and guides the antifreezing agent M onto the rotating disk 4 disposed obliquely below. 9 will be described.

  The receiving member 9 opens in a rectangular shape with a predetermined size long in the vehicle width direction of the vehicle B, and is formed in a trumpet shape in which one long side and both short sides are inclined upward. The receptacle member 9 is attached to the opening of the top plate 17 located obliquely below the discharge / drop port 2 so that the antifreezing agent M in the hopper 1 discharged and dropped from the discharge / drop port 2 can be removed. As shown in FIGS. 4 and 5, the guide is guided on the rotating disk 4 positioned in the traveling direction of the vehicle B with respect to the rotating spindle P.

In the spraying device A according to the present embodiment configured as described above, the spray guard for the first axis line X1 in the traveling direction of the vehicle B passing through the rotation axis P1 of the rotating disk 4 and the spraying direction of the antifreezing agent M. The angle θ1 of the member 7 in the rotation direction of the rotating disk 4 is preferably set in the range of 5 ° to 40 °. That is, the scattered material on the rotating disk 4 that is dropped (supplied) from the rotating shaft core P1 to the dropping position D closer to the traveling direction of the vehicle B is caught by the blade member 5 as the rotating disk 4 rotates and is rotated in the rotating direction. When it is carried, it moves toward the outside of the blade member 5 (in the disk outer circumferential direction).
For this purpose, as shown in FIG. 5, the first axis of the side edge portion 7 a of the one side edge portion 7 a of the scatter guard member 7 positioned across the first axis line X <b> 1 in the traveling direction of the vehicle passing through the rotation axis P of the rotating disk 4. The angle θ1 with respect to the straight line X1 and the angle θ1 with respect to the first axis straight line X1 of the other side edge portion 7b of the spraying guard member 7 positioned in the direction away from the first axis straight line X1 in the spraying direction of the sprayed material are 5 ° to 40 °. It is preferable to set in the range of °.
The reason is that if the angle θ1 is set to 5 ° or less, the sprinkled material travels from the one side edge portion 7a close to the dropping position toward the spraying direction behind the vehicle where the sprinkled material travels and is not pushed out. 5 is likely to be pushed out and pushed out toward the lower side of the paper surface, and the spatter that has been carried by the blade member 5 to the other side edge 7b of the spray guard member 7 is directed toward the rear spray direction of the vehicle. Although the sheet is pushed out and pushed out, there is a possibility that the direction in which the piece is pushed and pushed out is shifted downward in FIG. In other words, when the angle θ1 is 5 ° or less, the antifreezing agent M may not be evenly and universally spread across the road width (traveling lane) on which the vehicle travels, with the first axis line X1 as a boundary. This is because the antifreezing agent M may jump out to the side of the road and be consumed wastefully.
On the other hand, if the angle θ1 exceeds 40 °, it is possible to disperse and extrude the sprinkling material toward the spraying direction at the rear of the vehicle on the side edge portion 7a side of the spraying guard member 7, There is a possibility that the other side edge portion 7b side is pushed and pushed toward the upper side of the paper in FIG. 5 without being pushed and pushed toward the spraying direction at the rear of the vehicle, and is pushed and pushed toward the vehicle side. This is because it is difficult to achieve the intended purpose.
Therefore, in the spreading guard member 7 provided on the outer circumference of the disk in the rotation direction of the rotating disk 4 according to this embodiment, the angle θ1 with respect to the first axis line X1 is set in the range of 5 ° to 40 °, preferably 10 ° to Setting the range of 30 °, particularly preferably 25 °, is important for achieving the intended purpose.

Further, as shown in FIG. 5, the rotation axis P1 side is defined as a base point P2 that intersects the second axial line X2 in the diametrical direction passing through the rotation axis P1 of the rotary disk 4 on one end side located on the outer circumference side of the disk. The inclination angle θ2 of the blade member 5 disposed on the rotary disk 4 so that the other end side positioned at the position of the rotary disk 4 is away from the second axis line X2 in the rotation direction of the rotary disk 4 is 20 °. It is preferable to set in the range of ˜50 °.
The reason is that if the inclination angle θ2 is set to 20 ° or less, the scattered material caught by the blade member 5 moves toward the outside of the blade member 5 (in the outer circumferential direction of the disk) immediately after being caught. Get away. That is, there is a possibility that the blade member 5 may not be carried in the rotation direction. When the inclination angle θ2 exceeds 50 °, the scattered matter caught by the blade member 5 is not carried in the rotation direction by the blade member 5. This is because they are gathered in the direction of the rotational axis P1 of the rotating disk 4 and the spraying agents interfere with each other, so that the spraying direction due to the cooperation with the spraying guard member 7 is not fixed, which may become irregular.
Therefore, in the blade member 5 disposed on the rotating disk 4 according to the present embodiment, the inclination angle θ2 in the rotation direction of the rotating disk 4 with respect to the second axis line X2 is set in a range of 20 ° to 50 °. It is important to set a range of 35 ° to 45 °, particularly preferably 40 °. That is, by setting the inclination angle θ2 of the blade member 5 with respect to the second axis line X2 on the rotation disk 4 in the range of 20 ° to 50 °, the rotation disk of the spray guard member 7 with respect to the first axis line X1 described above. It is effective in achieving the intended purpose by synergistic action with the angle θ1 in the rotational direction of 4.

  In such a configuration, as shown in FIGS. 1 to 4 and FIG. 7, the spraying device A includes a stirring device 400 for manual operation over both side wall surfaces 1 c close to the discharge and dropping port 2.

The agitating device 400 is a device in which a spraying operator manually rotates the antifreezing agent M in the hopper 1, and as shown by a two-dot chain line in FIGS. 27, a rotating shaft body 401 made of a pipe material attached in an externally penetrating manner, an agitating shaft body 402 which is attached by changing the direction in three circumferential directions at several axial directions of the rotating shaft body 401, and the rotating shaft body 401 It is comprised from the handle 403 for manuals attached to one end side of this so that attachment or detachment is possible.
Thus, as shown in FIG. 7, the handle 403 is attached to one end side of the rotating shaft 401 projecting to the outside, and the rotating shaft 401 is rotated, thereby discharging and dropping by the respective stirring rods 402 in several axial directions. The antifreezing agent M near the mouth 2 is stirred. As a result, the anti-freezing material M in the hopper 1, in particular, the anti-freezing agent M near the discharge and dropping port 2 is prevented from being blitched, and the antifreezing agent M is quickly transferred from the discharge and dropping port 2 onto the rotating disk 4 during spraying. To fall naturally.

Further, in this embodiment, as shown in FIG. 7, the spraying device A can be supported by a pair of left and right stands C.
That is, as shown in FIGS. 1 and 6, a predetermined height position of the vertical frame member 107 attached between the lower frame member 105 and the intermediate frame member 106 on both the left and right sides constituting the device frame 100 of the spraying device A. Further, a connecting member 500 made of a round pipe material or the like is attached in a lateral opening shape. Then, as shown in FIG. 7, a horizontal hook member 501 provided with casters 502 and a vertical hook member 503 erected from the central portion in the length direction of the horizontal hook member 501, in a substantially reverse T-shape in a side view. A stand C is provided.

  In such a configuration, as shown in FIG. 7, the insertion connecting member 504 provided on the upper side of the vertical hook member 503 of the stand C is inserted and connected to the connecting member 500 on the apparatus frame 100 side so as to be detachable. The sprayer A can be supported on both the left and right sides. The insertion state of the insertion connection member 504 with respect to the connection member 500 can be connected so that it cannot be removed by pinning or the like.

The vertical hook member 503 of the stand C includes an upper side hook part 503a and a lower side hook part 503b made of a square pipe material. A screw hook member (not shown) provided in the upper side hook part 503a is used as a lower side hook part 503b. The upper-side collar part 503a is connected to the lower-side collar part 503b by being screwed into and inserted into a nut member (not shown) provided in FIG. The height of the upper side collar 503a can be adjusted by turning the handle 505 attached to the upper end of the screw collar projecting from the upper end of the upper side collar 503a (moving up and down with respect to the lower side collar 503b) Possible). After the height adjustment of the upper side flange 503a, the upper side flange 503a can be fixedly connected to the lower side flange 503b by pinning or the like.

[Description of operation]
Next, the use of the spraying device A according to the present embodiment configured as described above will be briefly described.
First, when the spraying device A is mounted on the rear part of the loading platform b of the vehicle B, a pair of left and right stands C shown in FIG. At this time, the abutting member 104 provided in the device machine frame 100 is applied to the rear side of the loading platform b, and the rear of the loading platform b without hitting the rotating disk 4 of the spreading unit 3 to the loading platform b. The spraying device A can be placed on the rear part of the loading platform b in a state where the rotary disk 4 or the like is positioned at a predetermined height from the road surface in FIG. After placing the spraying device A on the loading platform b, ropes and the like are bridged over the hooking members 102 at the four corners provided in the device frame 100 to fix the spreading device A on the loading platform b so that it cannot move. The power cable of the electric motor 6 of No. 3 is connected to a power supply unit such as a battery of the vehicle B so that power is supplied to the electric motor 6.

  In this way, when the spraying device A is mounted on the rear part of the loading platform b and then the antifreezing agent M is introduced into the hopper 1 and moved to the spraying site to perform the spraying operation, the electric motor 6 is operated by the spraying controller in the driver's seat. Is activated, and the electric cylinder 201 is activated in the shutter opening direction to open the shutter plate 200, whereby the spraying operation of spraying the antifreezing agent M toward the rear of the traveling vehicle B can be performed. At this time, by switching the number of rotations of the electric motor 6 with a volume knob provided in the spraying controller, the spraying operation can be performed with a spraying width L that matches the lane width of the traveling lane.

During the spraying operation, the antifreezing agent M accommodated in the hopper 1 is separated by the front side wall surface 1b and the both side wall surfaces 1c inclined toward the discharge drop port 2 at the lower center of the vertical rear side wall surface 1a of the hopper 1. It slides down by its own weight toward the discharge / falling port 2 (flows down). The antifreezing agent M that has slipped down to the discharge / falling port 2 is discharged onto the rotating disk 4 by the receiving member 9 that is disposed at an obliquely lower position (a position lower than the loading platform height of the vehicle B) from the discharge / falling port 2. It is dropped and pushed toward the rear (traveling lane) of the vehicle B traveling from the rotating disk 4 by the rotation of the rotating disk 4 and sprayed.
At this time, the antifreezing agent M guided to the receiving member 9 from the discharge dropping port 2 and falling to the dropping position D on the rotating disk 4 closer to the traveling direction of the vehicle B than the rotating shaft core P rotates the rotating disk 4. It is caught so as to be gripped with the rotating disk 4 by the blade member 5 disposed on the rotating disk 4 at an inclination angle θ2 with respect to the second axis line X2 passing through the axis P.

The antifreezing agent M caught by the blade member 5 moves to the outside of the blade member 5 (the disk outer peripheral side) by the rotation of the rotating disk 4, and yet passes through the rotation axis P of the rotating disk 4. It is carried in the rotational direction of the rotating disk 4 along the arc-shaped scattering guard member 7 attached so as to cover the outer periphery of the rotating disk 4 at a circumferential angle θ1 with respect to the straight line X1.
Then, the rotation direction of the rotating disk 4 is sequentially increased from the one side edge part 7a side close to the position D where the antifreezing agent M falls on the rotating disk 4 among the both side edge parts 7a and 7b of the spray guard member 7. The antifreezing agent M is discharged from the outer periphery of the disk that is not covered by the spreading guard member 7 reaching the other side edge 7b side, and is sprayed and sprayed at a spreading width L corresponding to the lane width of the traveling lane.

  Thus, according to the spraying device A according to the embodiment of the present invention, unlike the prior art, the hopper bottom is not provided with a screw or the like for dropping (supplying) the anti-freezing agent in the hopper onto the rotating disk. The antifreezing agent M in the hopper 1 can be sprayed in the spraying direction toward the back of the vehicle B and the spraying width (running lane width) L without waste while naturally dropping on the rotating disk 4.

That is, the antifreezing agent in the hopper 1 is formed by gradually inclining the front side wall surface 1b and the both side wall surfaces 1c toward the discharge / drop opening 2 provided at the lower center of the vertical rear side wall surface 1a of the hopper 1. M slides down (flows down) toward the discharge drop port 2 by its own weight. And the fall position D of the antifreezing agent M from the discharge drop port 2 onto the rotating disk 4 is closer to the traveling direction of the vehicle B than the rotation main shaft P of the rotating disk 4 guided (guided) by the receiving port member 9. Thus, the present invention has been completed by paying attention to the fact that the antifreezing agent M in the hopper 1 having a funnel shape constricted toward the discharge / falling port 2 is reliably dropped onto the rotating disk 4. Is.
Further, the spray width in which the antifreezing agent M dropped at the drop position D on the rotating disk closer to the traveling direction of the vehicle B than the rotational axis P is sprayed in the spraying direction toward the rear of the traveling vehicle B is used. In order to spread at L, both side edges 7a and 7b of the spreading guard member 7 curved in an arc shape with a length (arc length) corresponding to a semicircle of the rotating disk 4 are used as the disk of the rotating disk 4. The dispersal guard member 7 is provided on the outer periphery of the disk in the rotational direction of the rotating disk 4 in a state of being positioned within a predetermined circumferential angle θ1 with respect to the first axis line X1 in the traveling direction and the dispersal direction passing through the axis P. The present invention has been completed by paying attention.

Next, a mechanism for eliminating clogging of the antifreezing agent (snow melting agent) in the hopper 1 will be described. There are various shapes of anti-freezing agents to be put into the hopper 1, but broadly divided into granular materials, powdery materials, and flakes. Such an antifreezing agent has a characteristic that it easily absorbs moisture, and its fluidity deteriorates when the moisture is absorbed. The antifreezing agent whose fluidity has deteriorated due to moisture absorption does not fall in the hopper 1 from the rat hole or the discharge port 2 where only the upper part of the discharge port 2 falls and the surroundings solidify without collapsing. It becomes easy to raise | generate a bridge | bridging and it becomes difficult to discharge | emit the antifreezing material accommodated in the hopper 1 from the discharge | emission dropping port 2 continuously.

On the other hand, in another embodiment of the present invention, a hammer mechanism as shown in FIGS. 8 to 10 is provided. The hammer mechanism 600 is installed on the lower frame member 105 in front of the hopper 1, and intermittently taps the lower position of the front side wall surface 1 b of the hopper 1 from the outside, so that the antifreezing material in the hopper 1 is discharged and dropped 2 It has the function to discharge continuously from Since the space below the front side wall surface 1b in the hopper 1 is an empty space, the hammer mechanism 600 can be installed without increasing the size of the apparatus by installing the hammer mechanism 600 therein.

  The hammer mechanism 600 includes a hammer body 601 that strikes the front wall surface 1b, an arm 602 that is pivotally supported so that one end side that supports the hammer body 601 and the other end side that serves as the power point portion 602a swing vertically. A spring 603 that urges the other end side downward, and a drive unit 604 that rotationally drives a cam body 604A that lifts and releases the force point portion 602a of the arm 602 upward.

  The arm 602 is supported by a horizontal shaft 606 on which a support body 605 is installed at an intermediate portion so that both ends of the arm 602 can swing up and down. A hammer body 601 is attached to the front end side of the arm 602. In the illustrated example, a horizontal shaft 607 is provided between a pair of arms 602, and a drum-shaped hammer body 601 is attached so as to be supported by the horizontal shaft 607.

  One end side of the spring 603 is locked to the front end side of the arm 602, and the other end side is locked to the support body 605, thereby biasing the front end side of the arm 602 downward. Accordingly, the rear end side of the arm 602 to which the hammer body 601 is attached is urged upward by the spring 603.

  The drive unit 604 includes a cam body 604A and an electric motor 604B that rotationally drives the cam body 604A. The cam body 604A is rotationally driven by the constant and reduced speed of the electric motor 604B, and an intermittent period in which the hammer body 601 strikes the front side wall surface 1b at the rotational speed is set. The cam body 604 </ b> A that is rotationally driven repeats the function of lifting the force point portion 602 a of the arm 602 upward and releasing it by the front end portion contacting the force point portion 602 a of the arm 602. The electric motor 604B of the drive unit 604 is powered by a power source (battery: not shown) mounted on the vehicle B, and is turned on / off by a switch operation of a control box (not shown) installed in the driver's seat of the vehicle.

  10A to 10C show the operation of the hammer mechanism 600. FIG. The hammer mechanism 600 starts operation by turning on the electric motor 604B of the drive unit 604 during the spraying operation. When the cam body 604A is rotated by the rotation of the electric motor 604B, the front end side of the arm 602 is lifted up against the elastic force of the spring 603 only while the tip of the cam body 604A is in contact with the power point 602a of the arm 602. When the front end of the cam body 604A is separated from the force point 602a of the arm 602, the front end side of the arm 602 is pushed down by the elastic force of the spring 603 and the rear end side of the arm 602 is pushed up to the rear end side of the arm 602. The attached hammer body 601 hits the front side wall surface 1 b of the hopper 1.

  The cam body 604A is provided with a pair of tip portions at 180 ° around the rotation axis, and the hammer body 601 hits the front side wall surface 1b of the hopper 1 twice by one rotation of the cam body 604A. The intermittent cycle in which the hammer body 601 strikes the front wall surface 1b is preferably about once per second. For this reason, the rotational speed of the output shaft of the electric motor 604B (the rotational speed of the cam body 604A) should be set to about 30 rpm. Is preferred. The force with which the hammer body 601 strikes the front side wall surface 1b can be appropriately adjusted by the elastic force of the spring 603 or the like.

  By providing such a hammer mechanism 600, the spraying apparatus A according to the embodiment of the present invention can discharge the antifreezing material accommodated in the hopper 1 from the discharge / falling port 2 onto the rotating disk 4 without clogging. it can. Thereby, even when the antifreezing material absorbs moisture and the fluidity deteriorates, the spraying operation can proceed smoothly.

  When the hammer mechanism 600 is operated, a hammer sound is generated by the hammer body 601 hitting the front wall surface 1b. However, noise is suppressed by providing the hammer sound suppression member 610 at the contact position of the hammer body 601 on the front wall surface 1b. It becomes possible. The hammer sound suppressing member 610 is made of a laminate of a sponge material and a plastic material, so that it is possible to suppress the generation of hammer sound while applying an appropriate impact.

  The position at which the hammer body 601 strikes the front side wall surface 1b is a position below the front side wall surface 1b, and is preferably near the back surface of the discharge / falling port 2. By hitting the hammer body 601 at such a position, the antifreezing material in the hopper 1 is effectively discharged from the discharge / falling port 2 by effectively breaking the bridge and the rat hole. The hammer mechanism 600 is provided with a cover 611 that covers the drive unit 604 and the like as necessary.
