Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray hopper for storing a spray such as an antifreezing agent.

[0002]

2. Description of the Related Art On roads in cold or snowy areas,
As a means of minimizing traffic obstacles due to freezing of the road surface and snow accumulation, prevention of road surface freezing in severe cold, snow melting during snowfall,
To prevent freezing of the road surface after snow removal by a snow plow, a rotary snow plow, etc., and to melt snow and thaw ice, we spray antifreeze and the like.

[0003] Normally, spraying of an antifreezing agent or the like is performed by a spraying device mounted on a vehicle. FIG. 4 is a sectional view showing an example of a device for spraying a deicing agent or the like. The spraying device shown in this figure mainly includes a hopper 1 and a diffusion device 3. At the bottom of the hopper 1, a screw conveyor 2 as a conveying means is provided. The spraying agent such as an anti-freezing agent stored in the hopper 1 is sent out to the diffusion device 3 by the screw conveyor 2 and is spread and spread on the road surface by the rotating disk 4 of the diffusion device. In addition, a belt conveyor or the like may be used as a means for conveying the spraying agent, in addition to the screw conveyor.

[0004] The hopper of the spraying apparatus is usually formed in a funnel shape or an inverted triangular shape when viewed from the direction of conveyance of the conveyor.
The spraying agent stored in the hopper is dropped on the conveyor by its own weight. At this time, if the weight of the spraying agent loaded in the hopper is completely applied to the conveyor, it may be impossible to convey or break parts. In order to reduce the load applied to the conveyor, it is effective to provide a cover near the upper part of the conveyor. With this conveyor cover, the spraying agent falls on the conveyor by an appropriate amount through the gap between the inner wall of the hopper and the cover, so that the spraying agent can be reliably transported.

[0005]

However, in the hopper, calcium chloride (granules, flakes), raw salt (sodium chloride) or crushed salt as an antifreezing agent is contained.
In addition, various spraying agents such as sand and small pebbles are loaded as anti-slip agents. Depending on the type of these sprays,
Some fall smoothly and others do not. In the case of a spraying agent that is difficult to drop, as shown in FIG. 5, if the gap between the inner wall of the hopper 1 and the cover 5 is small, the conveyor portion (around the screw conveyor 2) becomes hollow, and spraying may not be possible.

In a conventional spray hopper provided with a conveyor cover, since the installation position of the conveyor cover is fixed, it is not possible to cope with various sprays, and in the case of a spray that is difficult to drop, it cannot be sprayed. There was a problem that sometimes.

Further, even if the spraying agent is of the same type, the dropping manner in the hopper differs depending on the temperature and humidity of the day or the period of being left unattended. The hopper having the above cannot provide good spraying. Changing the position of the conveyor cover according to the state of the spraying agent on that day is not easy with a conventional hopper, and at present it is not possible to perform optimum spraying.

The present invention solves the above-mentioned problems in the conventional spray hopper, and provides a spray hopper capable of easily adjusting the position of the conveyor cover with a simple structure and performing good spraying. The task is to

[0009]

SUMMARY OF THE INVENTION According to the present invention, there is provided a dispersant hopper having a conveying means at a bottom portion of a hopper for accommodating a dispersant and a cover member provided near an upper portion of the conveying means. The problem is solved by having an adjustment mechanism for adjusting the installation position of the member.

Further, in order to solve the above-mentioned problems, the present invention proposes that the adjusting mechanism is an adjusting device for adjusting an installation position of the cover member by a driving force.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the present invention, and FIG. 2 is a side sectional view thereof. In the hopper 1 shown in these figures, a screw cover 5 is suspended by a chain 6 from a bridge 7 which is bridged between upper ends of both sides of the hopper. Screw cover 5
Are provided at predetermined intervals above the screw conveyor 2 disposed at the bottom of the hopper. The screw cover 5 extends in the longitudinal direction of the conveyor 2 (usually in the front-rear direction of the vehicle on which the hopper is mounted). As the screw cover 5, any member such as a steel plate or a mold steel can be used.

Spray (not shown) contained in hopper
Is dropped onto the screw conveyor 2 by an appropriate amount through the space between the screw cover 5 and the inner wall of the hopper 1, and is conveyed by the screw conveyor.

[0013] However, the spraying agent to be stored in the hopper is various, and the state of the spraying agent is also various. When the position of the screw cover 5 is fixed, the dropping property of the spraying agent onto the conveyor is always kept optimal. No good spraying is done.

Therefore, in the present invention, the position of the screw cover can be easily changed. That is, in this embodiment, the hook member 8 is attached to the bridge 7,
The chain 6 is hooked on the hook member 8, and the screw cover 5 is suspended. For this reason, by changing the position of the loop of the chain 6 hung on the hook member 8, the length of the chain can be adjusted, and the hanging position of the screw cover 5 can be easily changed. Thereby, the distance between the conveyor 2 and the screw cover 5 (gap between the screw cover 5 and the inner wall of the hopper) can be easily adjusted according to the type of the spraying agent and the state of the spraying agent. Can be set. In this embodiment, the screw cover 5 is hung at two places near both ends in the longitudinal direction, so that the screw cover 5 is moved back and forth (on the conveyor 2).
The length of the chain can also be adjusted separately before and after the transport direction).

It should be noted that a similar effect can be obtained by using a shackle (link ring) or other connecting / latching member instead of the hook 8. The mounting method and the mounting position of the hook 8 are not limited to the present embodiment. Also, the number of chains is not limited to the present embodiment. For example, in the present embodiment, two chains 6 (see FIG. 1) viewed from the conveyor conveyance direction.
Although the screw cover 5 is supported, the screw cover 5 may be supported by one chain. Further, the screw cover 5 can be hung by a wire rope or the like instead of the chain 6. In that case,
In order to change the position where the hook 8 is hooked, a plurality of hooks (eg, ring-shaped portions) may be provided at different positions such as a wire rope. Furthermore, although the screw conveyor is used as the conveyor 2 in the present embodiment, it goes without saying that the present invention can be applied to a belt conveyor or a hopper using various known transporting devices.

Next, another embodiment of the present invention will be described. FIG. 3 is a sectional view showing another embodiment of the present invention. In the hopper 1 shown in this figure, the screw cover 5 is suspended by a wire rope 9.
The wire rope 9 is pulled out from a wire winding device 10 attached to the bridge 7, and has a screw cover 5 attached to the tip of the rope.

The wire winding device 10 is driven by a driving means such as an electric motor or a hydraulic motor, and is configured to be able to wind and extend the wire 9. The driving means of the wire winding device 10 can be controlled from an operation panel (not shown), and the length of the wire rope 9 can be adjusted by an instruction input by an operator. Thereby, the hanging position of the screw cover 5 can be changed very easily without requiring any labor, and the position of the screw cover 5 can be appropriately set even when a plurality of types of spraying agents are used. . Also, even with the same spray,
The position of the screw cover 5 can be set to an optimum position according to the state of the spraying agent.

In the present embodiment, since the length of the wire rope 9 can be automatically adjusted by using energy such as electricity or hydraulic pressure, when the chain is replaced by the chain suspension method, a finger is required. There is no danger such as scratching. If the operation panel is arranged outside the hopper 1, the hopper 1 is adjusted to adjust the position of the screw cover 5.
There is no need to get on top of or lean on
The danger accompanying that case can be prevented beforehand. Also,
Even if the upper part of the hopper 1 is covered with a net or a fence for safety, the position of the screw cover 5 can be easily adjusted without removing it.

Instead of the wire rope 9 and its winding device 10 in the present embodiment, it is possible to use a chain and a chain winding device. In addition, the combination of the means (member) for suspending (supporting) the screw cover 5 and the adjusting device for adjusting the length (adjusting the position of the screw cover 5) is limited to the present embodiment. is not.

[0020]

As described above, according to the spray hopper of the present invention, the position of the cover member can be easily changed, so that the conveying means (conveyor) provided at the bottom of the hopper and the cover member can be used. Distance can be easily changed according to the type and condition of the spraying agent, and even if multiple types of spraying agents are used, the appropriate position of the cover member can be set for various spraying agent conditions. Can be.

Further, by adjusting the installation position of the cover member by using the driving force by the adjusting device, the position of the cover member (the gap between the cover member and the conveying means) can be very easily adjusted without requiring any labor. Can be changed to In addition, the operation of adjusting the position of the cover member does not involve any danger, and the installation position can be adjusted very easily without any trouble.
