Description

TECHNICAL FIELD The present invention relates to a rolling compaction vehicle, and more particularly to a rolling compaction vehicle having a scraper.

2. Description of the Related Art Some roller vehicles having roller drums are provided with scrapers for removing dirt and the like adhering to the roller drums. (For example, Patent Document 1).

In the rolling compaction vehicle disclosed in Patent Document 1, the scraper is attached to the vehicle body so as to be rotatable around an axis extending in the width direction of the vehicle. The rolling compaction vehicle is configured so that the scraper can be held in three positions (working position, forwarding position, and maintenance position). Here, the working position means a position where the scraper comes into contact with the roller compaction drum and can scrape off dirt and the like adhering to the roller compaction drum. Further, the forwarding position means that the scraper is rotated from the working position, the tip of the scraper is positioned closer to the roller drum than the vertical plane including the end (front end or rear end) of the roller drum, and the scraper is It means a position that does not come into contact with the rolling drum. Further, the servicing position means a position where the scraper is further rotated from the forwarding position so that the tip of the scraper is on the side away from the roller drum with respect to the vertical plane.

Such a scraper is provided at a position close to the rolling drum, and is soiled with soil or the like. Therefore, when the operator directly touches the scraper, the operator's hands are soiled. For this reason, in the rolling compaction vehicle described in Patent Document 1, a handle is attached to the scraper in order to allow the operator to operate the scraper without directly touching the scraper (for example, FIG. 6 of Patent Document 1). ).

Patent No. 5704662

By the way, in the rolling compaction vehicle described in Patent Document 1, since the handle is fixed to the scraper, when the scraper is rotated between the working position and the maintenance position, the handle rotates together with the scraper to form a predetermined circle. draw a trajectory. That is, since the orientation of the hand of the operator holding the handle changes along the circular path when the scraper rotates, the orientation of the force applied to the handle by the operator also changes. For example, when rotating the scraper from the working position to the forwarding position, a force is applied mainly in an oblique direction toward the operator. , exert an upward force against gravity and an oblique force away from the operator himself. Therefore, as the scraper rotates, the burden on the operator who operates the handle increases.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and its object is to improve the operability of the scraper and to reduce the burden on the operator who rotates the scraper. To provide a pressure vehicle.

In order to achieve the above object, the compaction vehicle of the present invention includes wheels provided on a machine body including a compaction drum, a scraper for scraping off deposits adhering to the wheels, and provided on the machine body, a scraper support device that rotatably supports the scraper; and a gripping member that is supported by the scraper so as to rotate the scraper about the scraper support device, wherein the scraper support device is configured to support the scraper. a bracket to which is fixed, a bracket support that rotatably supports the bracket and is fixed to the airframe, and a plate-like engaging member that is rotatably supported with respect to the bracket support The bracket is fixed at a plurality of positions by rotating the engaging member and engaging or contacting the bracket in a plurality of positions, and the engaging member is attached to the bracket support. The bracket is rotatably supported around a rotating shaft, and the bracket is provided with a groove that fits and engages with one end of the engaging member, and the engaging member is bent with the rotating shaft as a base point, so that the engaging member is bent. It has a bent portion serving as an inner edge side of the bent portion, and in a state where one end of the engaging member is fitted into the groove and engaged, both ends of the engaging member are arranged closer to the aircraft body than the bent portion. The scraper includes a plurality of scraper bodies spaced apart in the vehicle width direction so as to contact the wheels, and a scraper holding the plurality of scraper bodies. and an auxiliary plate, wherein the gripping member is rotatably supported by a support portion provided on the scraper auxiliary plate and arranged between the plurality of scraper bodies in the vehicle width direction. and

According to the rolling compactor vehicle of the present invention, the gripping member is swingably supported by the support portion of the scraper. As a result, the gripping member can face the direction of the operator operating the gripping member regardless of the rotational position of the scraper. Therefore, it is possible to apply force in the same direction to the gripping member regardless of the rotational position of the scraper. Therefore, the direction of the force applied to the gripping member by the operator does not change along the circular orbit when the scraper rotates. For example, when pivoting the scraper between the working position and the servicing position, it is possible to apply an oblique force primarily directed at the operator, regardless of the position of the scraper. In other words, since the direction of the hand of the operator holding the gripping member does not change along the circular orbit when the scraper rotates, the operability of the gripping member can be improved, and the operator can easily operate the gripping member as the scraper rotates. can reduce the burden on
