Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a traveling lever structure of a floor material peeling machine that peels and rolls a carpet, a long sheet, a cushion floor, an artificial turf (hereinafter collectively referred to as floor material) from an adhesive base material.

[0002]

[Prior Art]

 This kind of flooring material needs to be peeled off and laid again when it gets old, but it is very difficult to peel off because the flooring material is firmly adhered to the adhesive base material (floor surface) with an adhesive or the like. For this reason, a floor material peeling machine having a peeling blade that vibrates back and forth in the traveling direction to peel the floor material was used, but this type of floor material peeling machine has a strong friction with the floor surface. In order to generate force and require subtle speed changes, the undercarriage is composed of a crawler traveling device, and the drive wheels are composed of a hydraulic motor that allows continuously variable shifting.

[0003]

[Problems to be solved by the device]

 The amount of pressure oil supplied to this hydraulic motor, that is, the machine speed is adjusted by the push / pull (forward / backward) position of the travel lever, but it is not possible to make fine position adjustments while leaving the travel lever in the air. It is very difficult because it is an operation that allows you to visually check the work status. The present invention addresses such a point, and in essence, it solves this problem by allowing the palm to grasp the traveling lever and the fixing member together.

[0004]

[Means for Solving the Problems]

 Under the above problems, the present invention relates to a floor material stripping machine which adjusts a traveling speed by adjusting an amount of pressure oil supplied to a hydraulic motor for driving a drive wheel by pushing and pulling a traveling lever. Provided is a traveling lever structure for a floor stripping machine, which is provided with a fixed bar that can be grasped together with the traveling lever with a palm in front of and behind the lever.

[0005]

[Operation] By taking the above means, the traveling lever can be grasped together with the fixed bar on the palm, so that the setting of the traveling lever to any position can be adjusted by adjusting the opening and closing of the palm, which is in a state of floating in the air. Much easier and more accurate than doing in.

【Example】

 FIG. 2 is a side view of the floor material peeling machine, and FIG. 3 is a plan view of essential parts. This floor material peeling machine supports a rotatable chassis 10 with a crawler traveling device 12 and a base portion at the rear of the chassis 10. 14, equipped with a control unit 16 at the front. A seat 18 on which an operator sits is provided on the upper surface of the base portion 14. In the crawler traveling device 12, a crawler 26 is attached to a drive wheel 22 and a driven wheel 24 attached to the front and rear ends of the track frame 20, of which the drive wheel 22 is directly equipped with a hydraulic motor. This hydraulic motor is driven by a hydraulic pump driven by an engine provided on the base 16 (both not shown).

Therefore, although the machine speed can be adjusted by changing the amount of pressure oil supplied to the hydraulic motor, the speed is controlled by the front and rear position of the traveling lever 28 provided in the control unit 16. . FIG. 1 is a perspective view showing the traveling lever 28. The traveling lever 28 projects upward from the control tower 30, and the forward speed becomes faster as it is tilted forward with the central neutral position interposed, and it is tilted backward. The reverse speed is set higher.

According to the present invention, in the above structure, the fixing bars 32 and 34, which can be grasped together with the traveling lever 28 by the palm, are provided in front of and behind the traveling lever 28, respectively. As a structure for this purpose, since a guard 36 is erected on the control tower 30 to protect the traveling lever 28 and the like, it is conceivable that the guard 36 is attached to the guard 36. That is, the front fixed bar 32 is directly attached to the upper side traverse portion of the guard 36, and the rear fixed bar 34 is such that the stay 38 is extended from the upper side traverse portion and can be attached to the stay 38. Be done. In addition to this, the control tower 30 is also provided with operation levers 42 for raising and lowering a stripping device 40 and the like, which will be described later, and adjusting the inclination angle thereof.

As described above, when the traveling lever 28 is operated to adjust the speed, if the vehicle is moving forward, the front fixed bar 32 and the traveling lever 28 are grasped together by the palm, so that the position of the traveling lever 28 can be adjusted. The adjustment can be done by opening and closing the part of the palm on the fixed bar, which allows fine position adjustment, that is, fine speed adjustment. Similarly, if the vehicle is moving backward, the rear fixed bar 34 and the traveling lever 28 may be grasped together with the palm.

A stripping device 40 is attached to the front part of the chassis 10 so as to be able to move up and down by a link mechanism 44. In this link mechanism 44, two links 46 and one hydraulic cylinder 48 form a parallel link, and a lifting hydraulic cylinder 50 is separately provided. Thus, when the lifting / lowering hydraulic cylinder 50 is expanded / contracted, the peeling device 40 moves up / down, and when the other hydraulic cylinders 48 forming the parallel links are expanded / contracted, the inclination angle of the peeling device 40 is changed.

FIG. 4 is a cross-sectional view of the main parts of the unwinding device. The unwinding device is attached to the swing head 54 which is vibrated (oscillated) about the horizontal shaft 52. The stripping blade 56 is made of thin spring steel. That is, an eccentric pin 62 is attached to a drive wheel 60 driven by the power of the engine 58, and the pin 62 and a pin 64 provided on the swing head 54 are connected by a rod 66. As a result, when the unwinding device 40 is lowered and the unwinding blade 56 is vibrated so as to act on the floor material 68 to run, the floor material 68 is unwound from the floor surface 70 (the unwound material is circular). Turn over). At this time, the stripping blade 56 is made of thin spring steel, and is set so as to be bent and pressed against the floor surface 60 at all times, so that the stripping blade 56 does not separate from the floor surface 70 even at the stroke end of the stripping blade 56. , Therefore, do not disconnect.

A dozer 72 is provided at the rear of the stripping device 40. The dozer 72 has a dozer plate 76 pivotally attached by a pin 78 or the like to an arm 74 or the like extending forward from the track frame 20 or the like. The tilt angle adjusting mechanism 80 allows the dozer plate 76 to rotate around the pin 78 to change the tilt angle. Due to the presence of the dozer 72, scraping scraps left unpeeled by the scraping device 40 are scraped off, and the scraping action of collecting and pushing the scraps is performed.

[Effect of the device]

 As described above, the present invention is the one described above, that is, the traveling lever can be grasped by the palm together with the fixed bar that is fixed. Since it can be adjusted by opening and closing the palm that can be fixed, fine position adjustment, that is, fine adjustment of speed, has become possible. In this respect, in the past, it was difficult to make fine adjustments because the traveling lever had to be fixed at an arbitrary position in the air while visually observing the working state.
