The application requires the rights and interests of the 61/299th, No. 526 U. S. application of application on January 29th, 2010, and the content of this application is combined in this by reference.

Background technology

As everyone knows, hand/hand held descaling machine (hand-operated/walk-behind scarifier) is used for removing mark and similar item from road surface and similar surfaces.Grinding/cutting moment of torsion horizontally rotates cutter and can make the operator feel extremely tired up to 13HP's.A large amount of vibrations pass to the operator from machine.These steamboats have limited the mobility of these machines.

The disclosure of invention

The present invention is used for high load capacity ground and carries out coating removal, cutting, grinding and smoothing.The present invention cleared up and prepared for example surface such as concrete and pitch before applying and applying.The design's main purpose is to remove usually and the device-dependent fatigue of this type.

The present invention can be connected to a propulsion unit, and for example, the trade mark of being sold by Graco company (Graco Inc.) is the propulsion unit of LineDriver.Allow like this by advancing and falling back and variable speed is carried out driving operations voluntarily.Feed depth gage allows grinding head only to cut according to desired depth.The degree of depth is adjusted by handwheel and acme thread (acme) nut and screw.

Radial type wheel car allows under the situation of not unclamping the handle of operating for ease and being equipped with, all to operate.It also allows especially on irregular road surface the pinniform translation and/or keeps impartial depth of cut.When cutter was applied to road surfaces, the length of pin joint and lever arm produced very little resistance or does not produce resistance.Be important to note that can make this pin joint from the position of handle further inwardly or to outside fix, thereby produce mechanical advantage more or less.

The present invention is equipped with an air supported head, and this air supported head allows cutting head to join in the cutting surface, and simultaneously, for safety, operator's both hands are positioned on the handle.This has also allowed the operator that cutter is floated on this surface, so that mark profile and carry out batch mixing (blend).This mechanism is made up of a latch arms that has C shape locking otch; This C shape locking otch engages with a bar with similar diameter; Gravity makes this arm keep locking, and exerts pressure and spur a trip lever with his or her finger tip to handle through the operator and discharge this arm.This depth controller has been set depth capacity, does not clear the jumps but do not limit the cutter rise, and this is important to the out-of-flatness surface, and on the out-of-flatness surface, cutting too dark or burning out cutter is a big problem.

Can adjust to satisfy the desirable requirement for height of operator handle and control panel (suddenly stop, tether braking (tether kill) and choke valve).Motor is connected on the cutter via centrifugal clutch, makes that owing to inertial load reduces starting is more easy.Provide an intake to be used for being connected with vacuum system.

Cutting/milling head carries out work with rotation mode, thereby has improved the removal ability.Under the situation that does not have the LineDriver unit, handle can easily move to anterior to carry out manual working.

The advantage that preceding runner provides is similar to uses the resulting advantage of Graco LineLazer: be easy to transportation and operation and locking straight path.

In order to reduce extra weight and vibration, the available amino end formic acid esters is filled these and is taken turns, and said carbamate has also been alleviated the needs to inflation.Two trailing wheels have been filled roughly 7 pounds, and front-wheel has been filled roughly 1.5 pounds.For example, competitive operation of equipment almost can produce immediately and numb, this numb identical with hand/arm because of numbing of producing of overvibration.

A unsteady axostylus axostyle has allowed head of the present invention to follow the profile on surface to be ground.The axostylus axostyle that should float will allow two big these unit of outboard wheel guiding, but still maintain the pressure on the less guide wheel.Can also be with the floating axle rod lock so that the irregular condition of extreme be compensated.

The operation of this type (especially surpassing the operation of 10HP) needs suitable equipment to handle load.Human body can only carry out this unconventional manipulation in the very short time interval.Use the LineDriver propulsion unit to overcome this problem.This unit is equipped with a safety interlock switch.Under the situation that does not obtain connecting in the LineDriver unit, this safety interlock switch will not allow this unit starting.

The present invention is a safety and to user-friendly solution, this scheme is used for high load capacity ground and carries out coating removal, cutting, grinding and smoothing, and realize that this purpose is through providing: the vibration of hand/arm is significantly reduced in (1); (2) it is tired significantly to reduce operator's manipulation; And (3) significantly increase control to cutter via handle.

These and other purpose of the present invention and advantage will combine accompanying drawing from following explanation, more fully to appear, and wherein, run through these views, and identical reference number is meant with some or similar part.
