Description

[Detailed Description of the Invention] [Industrial field of application] In heavy snow areas such as Niigata, pavement roads are scraped by spiked tires in winter, and asphalt powder accumulates on shoulders.
The sediment thus deposited is usually cleaned by a cleaning device called a so-called road sweeper in the spring when snow melts.

The present invention relates to an improvement of the cleaning device for the accumulated earth and sand accumulated on the road shoulders as described above.

[Prior Art] As shown in FIG. 4, a conventional device for cleaning sediment and the like, which is used for such a purpose, includes a traveling vehicle 1 and a cleaning mechanism 2 installed as an attachment in front of the traveling vehicle 1. Was configured. The cleaning mechanism 2 is, as shown,
Boom 3 connected to the vehicle side and equipped with an elevating cylinder (not shown); Arm 3'operated by arm cylinder 3a; Bucket 4 provided at the tip of boom 3 that can be divided into two, front and rear A main brush made of hard material such as iron that is rotatably provided in the traveling direction of the vehicle so as to rub the ground.
5, a main brush part consisting of a guide plate 6 such as earth and sand provided in front of the brush 5 and a bottom plate 7 for collecting earth and sand; a side cleaning provided on the front surface of the bucket 4 and rotatably provided on a horizontal plane Disk type gutter brush part 8: Comprised of a bucket opening / closing cylinder 4a and a caster roller 9.

In the conventional cleaning device, the worker travels to the place where the vehicle is to be cleaned, drives the cleaning mechanism 2, and removes the gutter brush 8 on the side (including the gutter) and the main brush 5 on the road. The sediment and sand in the vicinity of the center of the bucket 4 are temporarily stored on the bottom plate 7 of the bucket 4 via the guide plate 6, and when a predetermined amount of earth and sand is stored, the bucket 4
It was collected from the factory and prepared for the next cleaning.

[Problems to be Solved by the Invention] By the way, the conventional cleaning device is suitable for cleaning relatively soft soil, for example, removal of soft soil such as deciduous leaves accumulated on a paved road in a villa area. Effective for (cleaning), etc.

However, if the width of the accumulated sediment is large, cleaning cannot be performed in one work while traveling, and it is necessary to perform reciprocating travel or cleaning work while moving laterally.

Further, even when the road shoulder portion is inclined, the conventional gutter brush 8 can be adjusted in the vertical direction by the expansion and contraction operation by the arm cylinder 9a, but it does not have an adjustment mechanism for the lateral (horizontal) inclination. As a result, inconvenience occurred when cleaning the sediment deposited on such an inclined surface.

In addition, since the sediment deposited on the road shoulders in heavy snowfall areas has become extremely hard by drying and sticking by early spring, it is difficult to dig up with the above-mentioned brushes 5 and 8 using conventional cleaning devices. was there.

For this reason, conventionally, as an auxiliary, the motor grader is dispatched and the blade part is used to remove it, or the operator uses a scoop to remove it, which is a problem in using this type of cleaning device. It was.

[Means for Solving Problems] The present invention provides a cleaning device for accumulated sediment such as the above-mentioned problems by improving the structure of the gutter brush portion.

[Embodiment] The present invention will be described in detail with reference to the first and second embodiments of the present invention shown in Figs. In FIG. 1, components equivalent to those in FIG. 4 are designated by the same reference numerals.

FIG. 1 shows a gutter brush mechanism 10 of the present invention.
The structure of each part is as follows.

That is, 11 is the first attached to the front part of the bucket 4.
Support of which the free end is supported by the support B
It is attached to 11 'so that it can rotate horizontally. 12 is an angle cylinder attached to the front of the bucket for horizontal angle adjustment; 13 is these supports 1
1 ', an elliptical brush made of a hard material such as iron suspended by a cylinder 12. The brush 13 is connected to a drive gear 15 driven by a drive source 14 such as a hydraulic motor, and a driven gear 17 driven via a chain 16 wound around the gear, and is rotated by the torque of the drive source. ing.

Further, in the above structure, the brush mechanism 10 is rotated 90 degrees in the horizontal direction as indicated by the arrow X in (a) with the point P corresponding to the center of the column B as a fulcrum by the expansion and contraction operation of the cylinder 12.
As a result, the brush 13 is moved to the desired position such as the A position where the width of the brush 13 is maximum, the B position where it is the intermediate width, and the C position where it is minimum.
13 can be adjusted.

18 is a tilt cylinder, which is pivotally attached to one end of the support 11.
With the expansion and contraction of the cylinder, the brush mechanism 10 can be adjusted so as to tilt as indicated by an arrow Y, with the pivot point Q at the other end of the support 11 serving as a fulcrum.

FIG. 2 shows a second embodiment of the present invention. In the structure of FIG. 1, a spoon-shaped auxiliary brush 19 (for example, a hard material such as iron) is added to each tip of the brush 13. And an improved brush mechanism 10 '.

Other structures, that is, the above-mentioned gutter brush mechanism
The parts other than 10 or 10 'may have the same structure as the conventional one.

[Operation] In the cleaning device of the present invention, for example, when the width of the accumulated sediment is large in the lateral direction as shown in FIG. if rotating the brushes 13 and, L _1, an intermediate width position B in L _2, the minimum width position when the maximum width position a of the cleaning area can be processed at one time by the brush 13 is first diagram (b) In C, it changes to L ₃ and the processing capacity is increased or decreased according to the target soil and sand, and proper cleaning is performed.

Even if the state of the accumulated sediment is an inclined surface as shown in Fig. 3 (b), the inclination of the brush mechanisms 10 and 10 'with respect to the horizontal plane can be adjusted by expanding and contracting the tilt cylinder 18. According to the surface, θ ₁ and θ ₂ are properly adjusted to desired angles and cleaning is performed.

In any of these cases, when the improved brush mechanism shown in FIG. 2 is used, since the auxiliary brush 19 is provided at each tip of the brush 13, this brush 19
Since the cutting action is added by the method, it becomes more effective in removing the hard soil in the heavy snowfall area mentioned above.

[Advantages of the Invention] As described above, in the cleaning apparatus for accumulated sediment, etc. of the present invention, the gutter brush mechanism is improved so that the horizontal processing surface is adjustable and the horizontal inclination angle is also adjustable. With the features of.

Since the horizontal width of the brush 13 can be adjusted to an optimum value according to the state of the pile width of the earth and sand to be processed by the expansion and contraction operation of the angle cylinder, the work that was conventionally reciprocating can be performed during one running work. Now you can do it.

Since the angle of the brush 13 with respect to the horizontal plane can be adjusted to an optimum value according to the angle of the inclined surface such as earth and sand to be processed by the expansion and contraction operation of the tilt cylinder, effective and appropriate disposal of earth and sand becomes possible.

In the case of the second embodiment, since the cutting action of the brush is further strengthened, it becomes possible to easily clean the road shoulder portion in the heavy snowfall area, which in the conventional case requires supplementary cleaning work. It was
