Abstract
Description
[Technical Field]
[0001] The present invention relates to an antifreeze spreader vehicle, and more particularly to a mechanism for preventing arching action of antifreeze within a hopper. [Background technology]
[0002] Generally, an antifreeze sprayer vehicle comprises a hopper for storing antifreeze, a conveyor provided below the hopper, a chute provided at the end of the conveyor, and a rotating disk for spraying the antifreeze that falls from the chute to the rear of the vehicle (see Patent Documents 1 to 6).
[0003] In such antifreeze spreaders, a conveyor moves below the hopper to send out the antifreeze. As a result, the antifreeze at the bottom of the hopper is gradually used up, and normally, the antifreeze falls from above into the empty space. However, because the antifreeze is granular, if something happens, the granules may stick together and not fall properly, creating an arch-shaped cavity at the bottom of the hopper. This is called the arch action phenomenon or bridging phenomenon. Even if the arch shape does not form, the antifreeze may stick at the bottom of the hopper and not fall properly. This is called the blocking phenomenon. In the following explanation, these phenomena will be collectively referred to as the arch action phenomenon, etc.
[0004] In the antifreeze agent spraying vehicles described in Patent Documents 1 to 6, the arch action phenomenon and the like are not taken into consideration.
[0005] To prevent such arch action phenomena, a structure is known in which two mountain-shaped plates (hereinafter referred to as "arch action prevention plates") are installed inside the hopper, elongated horizontally in the direction of travel of the vehicle. For example, the two mountain-shaped plates shown in Figures 1 and 2 of Patent Documents 7 and 8 are arch action prevention plates (see Figure 7 of the present application). The arch action prevention plates are attached to plate members in the left-right direction of the vehicle, which are installed so as to straddle the left and right inclined surfaces of the hopper. Note that the arch action prevention plates also function as protective covers for the conveyor installed below the hopper, and are therefore also referred to as conveyor covers (hereinafter the same).
[0006] The anti-freezing agent in the hopper is separated into two parts by the anti-freezing agent, which flows down along the left and right slopes of the hopper. For this reason, it has been proven that arch action does not occur, and this type of anti-freezing agent has been used for many years.
[0007] In Patent Document 9, it is unclear whether arch action and other phenomena are prevented, but it claims that installing a vibrator (10) on top of a screen (8) at the bottom of the hopper (mesh for dropping the antifreeze onto the transfer conveyor) prevents the antifreeze from solidifying inside the hopper. Furthermore, in Patent Document 9, the housing that houses the vibrator (10) is triangular prism-shaped. However, this housing is merely a means for placing the vibrator (10) on top of the mesh, and is not the arch action prevention plate described in Patent Documents 7 and 8.
[0008] Patent Document 10 describes an antifreeze agent spreader that, in order to prevent the bridging phenomenon, provides a vertical wall (31) inside a hopper (3) and is equipped with a drive means (37) for moving this wall (31). The drive means (37) drives the wall inside the hopper (3) in a reciprocating or vibrating manner, forcing movement of the antifreeze agent inside the hopper (3), thereby preventing solidification of the antifreeze agent above the screw conveyor (5) and preventing the bridging phenomenon.
[0009] Patent Document 11 describes a spraying device in which a hammer mechanism (600) is provided on the outside of the lower part of a hopper (1) so that an antifreeze agent can be continuously discharged. [Prior art documents] [Patent documents]
[0010] [Patent Document 1] Japanese Patent Application Publication No. 11-222827 [Patent Document 2] Japanese Patent Application Laid-Open No. 2000-27139 [Patent Document 3] Japanese Patent Application Laid-Open No. 2002-173923 [Patent Document 4] Japanese Patent Application Laid-Open No. 2006-161471 [Patent Document 5] Japanese Patent Application Laid-Open No. 2012-144888 [Patent Document 6] Japanese Utility Model Application Publication No. 5-94308 [Patent Document 7] Japanese Patent Application Laid-Open No. 2010-24723 [Patent Document 8] Japanese Patent Application Laid-Open No. 2011-94450 [Patent Document 9] Microfilm of Utility Model Application No. 63-65015 [Patent Document 10] Japanese Patent Application Laid-Open No. 2004-324291 [Patent Document 11] Patent No. 6646529 Summary of the Invention [Problem to be solved by the invention]
[0011] The arch action prevention plates described in Patent Documents 7 and 8 were simple yet effective in preventing arch action. However, recently, cases have occurred in which the arch action prevention plates alone were unable to prevent the arch action of antifreeze. While it will take more time to clarify the exact physical reasons why such cases are likely to occur, it is thought that the antifreeze particles used in recent years are smaller than those used traditionally, making them more likely to stick together, and as a result, arch action and other phenomena are more likely to occur.
[0012] Therefore, an object of the present invention is to provide an antifreeze sprayer that uses an arch action prevention plate and can further prevent the occurrence of arch action phenomena, etc.
[0013] The device described in Patent Document 9 does not use an arch action prevention plate. Also, simply placing a vibrator on top of the mesh does not transmit vibrations to the entire area, so it is unclear whether arch action can be reliably prevented.
[0014] At first glance, the device described in Patent Document 10 appears to have a mountain-shaped plate (33), but the plate (33) is not an arch action prevention plate. The device described in Patent Document 10 prevents the bridging phenomenon by causing the vertical wall (31) to vibrate.
[0015] The device described in Patent Document 11 vibrates the hopper (1) itself using a hammer mechanism (600), and is not an antifreeze agent spraying vehicle that uses an arch action prevention plate. [Means for solving the problem]
[0016] In order to solve the above problems, the present invention has the following features: The present invention is an antifreeze spraying vehicle that transports antifreeze stored in a hopper to the rear of a vehicle using a transport conveyor below the hopper, and sprays the antifreeze transported from the transport conveyor to the rear of the vehicle using a rotating disk, and inside the hopper, there is a rotating disk that rotates in the front-to-rear direction of the vehicle above the transport conveyor. Two pieces are fixed together and stretched to form an inverted V-shaped cross section. Anti-arch action plates are installed. A stand for mounting a vibrator is provided, which is positioned inside two arch-action prevention plates so as to straddle the left and right sides, and is equipped with a vibrator stand fixed to the two arch-action prevention plates. The vibrator is fixed to the vibrator stand, and the vibration of the vibrator is transmitted to the entire arch-action prevention plate via the vibrator stand. The vibration of the vibrator causes the arch-action prevention plate to vibrate, loosening the antifreeze agent around it and preventing adhesion and arch action within the hopper. It is characterized by:
[0017] Preferably, the apparatus further comprises a vibrator base attached to the lower part of the arch action prevention plate, and the vibrator is attached to the vibrator base.
[0018] Preferably, the vibrator is provided in the hopper at the front of the vehicle.
[0019] Preferably, the vibrator vibrates automatically when the transport conveyor is in operation.
[0020] Preferably, the vibrator automatically adjusts the vibration intensity in accordance with the speed of the transport conveyor or the vehicle speed.
[0021] Preferably, the device further includes a volume for adjusting the intensity of the vibration of the vibrator.
[0022] Preferably, the apparatus further comprises a fixing member for fixing the arch action prevention plate within the hopper, and a portion of the fixing member is tapered.
[0023] In addition, the present invention is a device for transporting antifreeze stored in a hopper provided on a vehicle to the rear of the vehicle using a transport conveyor below the hopper, and scattering the antifreeze transported from the transport conveyor to the rear of the vehicle using a rotating disk. Ru-freeze In the method for spraying anti-scalding agent, the inside of the hopper is provided with a conveyor belt arranged in the front-rear direction of the vehicle. Two pieces are fixed together and stretched to form an inverted V-shaped cross section. Anti-arch action plates are installed. A stand for mounting a vibrator is provided, which is arranged so as to straddle the two arch-action prevention plates on the inside of the two plates, and a vibrator stand is provided which is fixed to the two plates. The vibrator is fixed to the vibrator stand, and the vibration of the vibrator is transmitted to the entire arch-action prevention plate via the vibrator stand. The vibrator is activated to vibrate the arch-action prevention plate, and the vibration loosens the antifreeze agent around the arch-action prevention plate, preventing adhesion and arch action within the hopper. The antifreeze agent dropping from the hopper is transported to the rear of the vehicle using a transport conveyor and sprayed by a rotating disk. [Effects of the Invention]
[0024] According to the present invention, a mountain-shaped anti-arch action plate is used inside the hopper, and the effect of the anti-arch action plate prevents arch action phenomena, etc. In addition, by vibrating the anti-arch action plate with a vibrator, it is possible to prevent the anti-freeze agent from adhering, further preventing the occurrence of arch action phenomena, etc.
[0025] By attaching the vibrator stand to the bottom of the arch action prevention plate and attaching the vibrator to the vibrator stand, it is possible to reliably transmit the vibration of the vibrator to the arch action prevention plate. This allows the arch action prevention plate to vibrate evenly, making it possible to prevent arch action phenomena and the like.
[0026] By attaching the vibrator to the front of the vehicle inside the hopper, arch action phenomena and the like can be prevented at the bottom of the hopper in front of the vehicle, where arch action phenomena and the like are likely to occur.
[0027] By automatically vibrating the vibrator while the transport conveyor is in operation, it is possible to prevent arch action and other phenomena, and the operator can concentrate on driving the vehicle, thereby increasing safety.
[0028] The strength of the vibration is automatically adjusted according to the speed of the transport conveyor or the vehicle speed, making it possible to prevent arch action and other phenomena.
[0029] By providing a volume, the operator can prevent arch action and other phenomena depending on the situation.
[0030] By thinning a portion of the fixing member of the arch action prevention plate, the flow of antifreeze inside the hopper is improved, allowing for smoother transport.
[0031] These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. [Brief explanation of the drawings]

[0033] In Figure 1, the antifreeze spraying vehicle 1 comprises a hopper 2, a transfer conveyor 3 provided below the hopper, a chute 11, and a rotating disk 4. The antifreeze contained in the hopper 2 falls from the bottom of the hopper 2 onto the transfer conveyor 3.
[0034] The bottom of the hopper 2 is open in the longitudinal direction of the vehicle. The transfer conveyor 3 is provided below the open hopper 2. The transfer conveyor 3 rotates in sync with the vehicle speed. That is, if the vehicle speed is fast, the transfer conveyor 3 also rotates faster, and if the vehicle speed is slower, the transfer conveyor 3 also rotates slower. This allows the appropriate amount of antifreeze to be dropped into the chute 11 in accordance with the vehicle speed.
[0035] The antifreeze agent dropped into the chute 11 falls from the chute 11 onto the rotating disk 4. As the rotating disk 4 rotates, the antifreeze agent that has fallen can be dispersed behind the vehicle. The rotation speed of the rotating disk 4 may also be controlled appropriately.
[0036] 2 to 4, plate members 7 are attached in the left-right direction of the vehicle inside the hopper 2 so as to straddle the left and right inclined surfaces. Although three plate members 7 are shown here, the number does not limit the present invention.
[0037] A hinge 6 is attached to the top of the two arch action prevention plates 5, 5. The number of hinges 6 is not a limitation of the present invention.
[0038] Mounting plates 5a are provided on the left and right lower ends of the arch action prevention plate 5. A plurality of arc-shaped mounting holes 10 are provided in the plate member 7. By fastening the mounting plates 5a to the mounting holes 10 with fastening means such as bolts and nuts, the two arch action prevention plates 5, 5 can be attached inside the hopper 2 in a mountain shape (inverted V-shape).
[0039] The arch action prevention plates 5, 5 are attached across the front-to-rear direction of the vehicle, slightly below the middle inside the hopper 2. Two sets of arch action prevention plates 5, 5 are shown here, but two long arch action prevention plates 5, 5 may be used to form one set, or two short arch action prevention plates 5, 5 may be used to form three or more sets.
[0040] As described above, conventionally, the arch action prevention plates 5, 5 are attached inside the hopper 2, above the transport conveyor 3, in the longitudinal direction of the vehicle. In this embodiment, a vibrator stand 8 is further attached to the arch action prevention plates 5, 5, and a vibrator 9 is attached on top of the vibrator stand 8.
[0041] Specifically, two vibrator stands 8 are attached to the lower part of the two arch action prevention plates 5, 5 that are spread out in an inverted V shape, on the front side of the vehicle (see Fig. 2). As shown in Fig. 5, the vibrator stand 8 has a bottom 8a and left and right bent parts 8b, and has mounting holes. A vibrator 9 is attached to the bottom 8a of the vibrator stand 8.
[0042] Here, the vibrator 9 is an electric vibrator, but it may be a hydraulic vibrator. The structure of the vibrator 9 is not particularly limited as long as it vibrates.
[0043] Here, two vibrator stands 8 are provided on the front side of the vehicle of the arch action prevention plates 5, 5, and a vibrator 9 is provided on each, but it is sufficient that at least one vibrator stand 8 and one vibrator 9 are provided.
[0044] By providing two vibrators 9, it is possible to use one vibrator 9 as a spare in case the other vibrator 9 breaks down.
[0045] The vibrations of the vibrator 9 are transmitted to the arch action prevention plates 5, 5 via the vibrator stand 8. This transmits the vibrations to the antifreeze around the arch action prevention plates 5, 5. This vibration prevents the antifreeze from solidifying. As a result, when the transfer conveyor 3 is driven, the antifreeze falls smoothly into the space at the bottom of the hopper 2 where it has run out, preventing the occurrence of arch action and other phenomena.
[0046] Next, an example of control of the vibrator 9 will be described.
[0047] (For manual control) The two vibrators 9 can be manually turned on and off using independent switches (not shown). That is, one vibrator 9 can be turned on and the other can be turned off, or both vibrators 9 can be turned on simultaneously.
[0048] However, when both vibrators 9 are turned on, a counteracting effect occurs and the arch action prevention plates 5, 5 must vibrate, so the operator should adjust the on / off settings as appropriate, taking into account the spraying conditions.
[0049] Also, a volume is attached to each vibrator 9 so that the strength of the vibration of the vibrator 9 can be adjusted.
[0050] In addition to such manual control, it is also possible to automatically turn the vibrator 9 on and off.
[0051] (In the case of automatic control) The transfer conveyor 3 may be automatically controlled so that one of the vibrators 9 is turned on when it is driven. Which vibrator 9 is turned on is determined based on a predetermined rule (for example, periodically switching the vibrator 9 to be turned on).
[0052] Since arch action and other phenomena are likely to occur when the transport conveyor 3 is in operation, such automatic control can prevent arch action and other phenomena, allowing the operator to concentrate on driving the vehicle.
[0053] In the case of automatic control, the intensity of vibration of the vibrator 9 may be automatically adjusted in accordance with the speed or vehicle speed of the transport conveyor 3. For example, when the speed or vehicle speed of the transport conveyor 3 is high, the vibration of the vibrator 9 may be automatically controlled to be increased or decreased.
[0054] Here, the vibrator 9 is provided inside the hopper 2 on the front side of the vehicle. This is based on the empirical reason that the arch action phenomenon and the like are more likely to occur at the front side of the vehicle. However, the present invention is not limited to providing the vibrator 9 at the front side of the vehicle, and the vibrator 9 may be provided at various locations on the arch action prevention plates 5, 5, such as near the center of the hopper 2 when viewed from the front, on the rear side of the vehicle, at the front and rear of the vehicle, or at the front, rear, or center of the vehicle.
[0055] Here, a vibrator stand 8 is provided at the bottom of the inverted V-shaped arch action prevention plates 5,5 to vibrate the arch action prevention plates 5,5, but the vibrator 9 may also be attached directly to the arch action prevention plates 5,5.
[0056] (Modification of plate member 7) In the above embodiment, the plate member 7 is used to attach the arch action prevention plates 5, 5 to the hopper 2. However, the plate member 7 may prevent the antifreeze from flowing smoothly inside the hopper 2. Therefore, by thinning a portion of the plate member 7, the antifreeze can flow more smoothly.
[0057] Specifically, as shown in Figure 6, supports 7b, 7b are attached to the left and right sides of the inside of the hopper 2, the arch action prevention plates 5, 5 are fixed with plates 7a, and the supports 7b, 7b and plates 7a are connected with pipes 7c, 7c, thereby fixing the arch action prevention plates 5, 5 inside the hopper 2.
[0058] The structure of thinning a portion of the plate member 7 can be provided in the central portion of the hopper 2 and toward the front of the vehicle, as shown in Figure 6, to improve the flow of antifreeze, but is not limited to this.
[0059] In this way, by spanning the inside of the hopper 2 with fixing members having at least a narrowed portion, and using these fixing members to fix the arch action prevention plates 5, 5 inside the hopper 2, it is possible to improve the flow of antifreeze inside the hopper 2. Note that in the example of Fig. 6, plates 7a, supports 7b, 7b, and pipes 7c, 7c are used as fixing members, with the pipes 7c, 7c being narrower than the others, but this is not limited to this as long as only a portion is narrowed, and instead of the pipes 7c, 7c, round bars or rectangular bars may be used, or part of the plate member 7 may be hollowed out to make it narrower.
[0060] In the above embodiment, two arch action prevention plates 5, 5 are used, but a mountain-shaped arch action prevention plate may be manufactured by bending a single plate as long as it is configured in a mountain shape. Therefore, in this invention, the invention is defined as a mountain-shaped arch action prevention plate attached to the top of the transport conveyor in the fore-and-aft direction of the vehicle.
[0061] Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit its scope. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. Each of the constituent elements of the invention disclosed in this specification is considered to be an independent, stand-alone invention. Inventions in which the constituent elements are combined in any manner are also included within the scope of the present invention. [Industrial Applicability]
