Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sprayer for dispersing road surface antifreeze, cut stone, gravel, etc. (hereinafter referred to as aggregate, etc.) onto a road surface.

[Conventional technology]

Generally, an aggregate spreader is used by being mounted on a truck such as a truck, and consists of a base that supports a hopper, a conveyor, and a chute, a support protruding from the base, and a support. The sprayer is equipped with a dispensing device consisting of a discharge tube mounted on the chute and positioned below the chute, a dispersion disk, and a drive motor for the dispersion disk. The aggregate, etc., which has been placed in the hopper in advance, is sent out at an appropriate speed from the discharge port below the hopper onto the conveyor, and is spread onto the road surface via a chute by a scattering device placed below the chute. -ing

By the way, when spreading aggregate, etc., the minimum amount of aggregate, etc. required is put into the hopper, and care is taken to ensure that no aggregate, etc. remains in the hopper when the spreading work is finished. . In actual spraying work, it is normal for aggregate etc. to remain in the hopper at the end of the work, and if this remaining state is left unattended,
Deterioration of aggregates, etc., and especially coagulation of road antifreeze agents such as calcium chloride and sodium chloride, were major obstacles to subsequent spraying operations.

Therefore, it has become essential to carry out a separate operation to discharge the aggregate remaining in the hopper at the end of the scattering operation.

However, in a scattering device, the effective cross-sectional area of the discharge tube that sends out aggregate, etc. and the scattering capacity of the scattering disk are closely related, so if the discharge speed from the hopper is increased, A situation may occur in which a large amount of material, etc. remains in the discharge cylinder, and
Even if an attempt was made to increase the effective cross-sectional area of the discharge tube to prevent accumulation, there was a problem in that the discharge tube alone could not be expanded due to its relationship with the dispersion disk.

Furthermore, in the conventionally structured spreading device, the spreading disk is placed on the road surface in order to uniformly spread aggregates etc. on the road surface.
It is installed at a height of 400 to 500 mm, and the trays for discharging aggregates, etc., are limited to those of short size and small capacity, and the work of discharging the remaining aggregates, etc. requires the hassle of replacing the trays many times. There it was.

It is also possible to use a large-capacity tray to speed up the discharge process, but in this case,
We had no choice but to remove the spraying device from the frame, create a large space below the chute, and then discharge directly from the chute into a large-capacity receiving tray, which required a great deal of effort to attach and remove the spraying device. This resulted in inefficient work.

[The problem that the idea aims to solve]

The problem that we are trying to solve is that conventionally structured aggregate spreaders require a considerable amount of time, effort, and effort to discharge the aggregate remaining in the hopper due to the amount of discharge and the receiving tray. That's what I was doing.

[Means to solve the problem]

The present invention includes a base that supports a hopper, a conveyor, and a chute, and a support that protrudes from the base and positions a spreading device consisting of a discharge tube, a spreading disk, and a drive motor below the chute. In a spreader for aggregate, etc., a protective member is rotatably pivoted in the horizontal direction on the outer end of a support protruding from the base, and a protective member is mounted on the inner side of the protective member and positioned below the chute. They installed a spraying device to do this.

Furthermore, the protective member may include a bracket on its inner side that is rotatably pivoted in a horizontal direction relative to the support, and a dispersion device located below the chute may be attached to this bracket.

[Effect]

During the spreading operation, the spreading device consisting of the discharge tube, the spreading disk, and the drive motor is fixed to the lower part of the chute by the locking device, and when the remaining aggregate etc. is discharged after the spreading operation, the locking device is is released and the spraying device is rotated horizontally around the shaft attachment part, thereby forming a large space below the chute.

In this state, a large-capacity receiving tray is placed below the chute to discharge the remaining aggregate, and when discharge is complete, the spreading device is rotated horizontally and fixed to the bottom of the chute by a locking device.

At this time, the dispersing device is protected by the protective member at the outer end, and the dispersing device rotates as the protective member rotates the dispersing device.

〔Example〕

Hereinafter, an embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a truck such as a truck;
is equipped with a base A that supports a hopper 2, a conveyor 3, and a chute 4. Reference numeral 5 denotes a support protruding from the rear end of the base A. A protective member 9 is disposed on the outer end of the support, and a discharger located below the chute 4 is provided inside the protective member 9. A spreading device B consisting of a cylinder 6, a spreading disk 7, and a drive motor 8 for the spreading disk 7 is attached. Reference numeral 10 denotes a shaft attachment part that allows the protection member 9 to rotate freely in the horizontal direction with respect to the support body 5, and as the protection member 9 rotates around the shaft attachment part 10, the spraying device B also rotates. It rotates horizontally from below 4 and returns to its original position.

In the embodiments shown in FIG. 5 and later, a bracket 11 having a protective member 9 disposed at its outer end is pivotally attached 10 to a support 5 protruding from a base A so as to be rotatable in the horizontal direction. The spraying device B, which is located below the chute 4, is attached to the bracket 11, that is, to the inner side of the protective member 9.

Reference numeral 12 denotes a locking device for fixing the spraying device B below the chute 4, and 13 indicates a locking device for bending the protruding portions on both sides of the protective member 9 as necessary as the spraying device B rotates in the horizontal direction. It is a hinge for

In the embodiment shown in the drawings, the protective member 9 is formed to protrude from both sides to form a bumper shape, but the protective member 9 does not necessarily have to be bumper-shaped. Any shape that can protect device B is sufficient.

In addition, the bumper of a vehicle, etc., which serves as a so-called shock absorber, is attached to either the trolley 1 or the base A, but in either case, the bumper is attached to the outermost end behind the protective member 9. Of course, it can be attached to

[Effect of idea]

As mentioned above, in this invention, the spreading device located below the chute can be rotated in the horizontal direction, so that it can be used to discharge the aggregate, etc. remaining in the hopper after the spreading work of aggregate, etc. is completed. By rotating the spraying device horizontally around the shaft attachment part, a large space can be created below the chute, and a large-capacity receiving tray can be arranged below the chute for efficient discharge work. can be done.

In addition, the spraying device is attached to the inside of a horizontally rotatable protective member and is protected by the protective member, which prevents danger to spraying workers and allows for highly safe spraying work. It can be done.

Furthermore, by providing a bracket for attaching the dispersion device to the inside of the protective member and rotatably attaching it to the support, the protective member becomes stronger.
Moreover, not only the attachment of the dispersing device becomes more reliable, but also the rotatable shaft attachment to the support body can be ensured.
