Description

[Detailed Description of the Invention] This invention relates to a tine rotor device that affects the crushing and agitating portion of a load stabilizer.

As shown in Fig. 1, the general configuration of a road stabilizer as a roadbed construction machine is that tines T are cantilevered at the rear of a self-propelled vehicle body V, and inside a semicylindrical tine cover C, A tine rotor device R is horizontally suspended, and the rotation of the rotor device R stabilizes the roadbed.

By the way, according to the conventional rotor device, the tips of each tine blade protrude in the radial direction from the tip of the arm, so the arm sides of the side end blades located at both ends of the rotor rotation axis are exposed to the asphalt layer during roadbed construction. The agitation operation is performed while the blades are in direct contact with each cut wall surface of the crushed stone roadbed, and as a result, only the arms of the side end blades are significantly worn, but unlike the tips, the arms cannot be replaced when they wear out. As a result, the durability of the tine rotor as a whole is unnecessarily shortened due to the arms at the side ends.

The present invention eliminates the above-mentioned drawbacks by making the width of the crushing operation of the road bed wider than the width of the stirring operation.In other words, the purpose of the present invention is to An object of the present invention is to provide a tine rotor device in which a gap is formed between the tine rotor and the rotor.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

- As shown in FIGS. 1 to 5, the rotor device of the embodiment includes a rotor rotating shaft 1 that is driven by power with both ends bearing on tine covers (not shown), and a rotor rotating shaft 1 that is parallel to the same shaft 1. A plurality of shafts (in the illustration, one

is bolted to.

By the way, each arm 3 of the side end blades H0 and Hll and each arm 4 of the intermediate blades H2 to H1o are each formed of a cross-shaped plate with a center hole. The arm width on the diameter of the two opposing arms is approximately 2
It has been expanded to double its size so that two chips (described later) can be attached.

However, in order for these vanes H1 to H11 to be attached to each ring 2, they are bolted to each other with an 18" operating phase shifted, and the rotational phase angles shown in the drawings are based on the traveling direction of the car body. The angle θ° is shown as an angle (360') along the rotational force direction a of the shaft 1.

Next, near each of the four ends of each intermediate arm 4, a mounting frame 5 having a U-shaped cross section is fixed on one surface, and a tent-shaped stirring plate 6 is fixed on the opposite surface. A crushing chip 7 made of a long plate is inserted into each mounting frame 5, and is fixed to the arm 4 with bolts 8.

Note that a portion of the leading end of each tip 7 on the advancing side is a carbide blade portion 7a.

゛On the other hand, mounting frames 5 are fixed on both sides near each wide diametrical tip of the side end arm 3, and a pair of tips 7 are similarly fixed to each mounting frame 5. Further, a mounting frame 5 and a stirring plate 6 are fixedly installed on the outer and inner surfaces of the vicinity of each diametrical tip having the same width as the arm 4, respectively, and the mounting frame 5 has an L-shaped An overhanging tip 9 is fixed, and a portion of the lateral overhanging portion of the tip 9 on the advancing side is a carbide blade portion 9a.

The operation of the tine rotor device of the embodiment configured as described above is as shown in FIG. After the pavement asphalt layer 10 is crushed by the rotational impact of the chips 7.9, the crushed stone roadbed 11 is crushed by the chips 7.9, and the roadbed 11 is agitated by the pushing and spreading of the plate 6.

However, in the operation of the apparatus of this embodiment, since the tip of the overhanging tip 9 overhangs laterally, a gap is created between the plate 3 and the cutting wall surface of the layer and disk 10 and 11. , the wear degree of the side end arm 3 is the same as that of the intermediate arm 4.
There is no particular difference in the degree of wear from that of , that is, uneven wear of the device component members has been eliminated.

As described above, according to the tine rotor device according to the present invention, only the crushing tip 7 made of a long plate with the cutting edge in the radial direction is provided at the tip of the intermediate arm located in the middle of the rotation axis, and the arm Since the stirring plate 6 is protruded from the side wall surface near the tip of the roadbed, when the paved roadbed is to be regenerated, powerful crushing and stirring of the crushed roadbed can be done at the same time. Moreover, since only the L-shaped tip 9 with the cutting edge protruding outward is made to protrude from the tips of the arms 3 on both sides, regardless of the above-mentioned powerful driving crushing work, it is possible to cut the base course by cutting the vertical wall. This has the effect of eliminating uneven wear of the arms as device constituent members at both ends.
