The present invention relates to a kind of land leveller that is suitable for flattening such as soil or ground.Though a kind of application of the present invention relates to the smooth of soil, this machine also is applicable to snow on the smooth for example ski trail or the like.
At present, known land leveller generally comprises a massive scraper plate, and this scraper plate is suitable for moving through the ground that is flattened.Usually, these devices are relatively heavier and handle difficulty, can not use on narrow location.
The object of the invention is to provide a kind of improved land leveller, and this land leveller is eased above-mentioned one or more problems.
According to the machine on leveling provided by the invention surface, can on its normal direct of travel, move through this surface.This machine comprises: a main frame; Ground operation device, it movably is connected on the above-mentioned main frame, so that can be with respect to main frame vibration or swing, above-mentioned ground operation device comprises smooth scraper plate at least, this level land scraper plate is in the transversely extension of the normal direct of travel of machine.
Ground operation device preferably includes polylith level land scraper plate, and these scraper plates are usually parallel to each other and in the transversely extension of the normal direct of travel of machine, and their certain distances that is spaced from each other on the normal direct of travel of machine.Above-mentioned every level land scraper plate all has a smooth substantially earthed surface, when land leveller in use, this surface tilts with respect to working face, its leading edge above working face than trailing edge height.Polylith level land scraper plate is preferably disposed in the plane, and during use, this plane tilts with respect to working face, and wherein top level land scraper plate is scraped plate hight than rearmost level land above working face.
Vibration or swing preferably can cause ground operation device to do usually on the normal direct of travel of machine with respect to main frame and move back and forth.
In a most preferred embodiment, ground operation device movably is connected on the main frame by a plurality of connecting rods, one end of every connecting rod is connected on the main frame pivotally, and the other end is connected on the above-mentioned ground operation device pivotally, this set makes ground operation device hang by each connecting rod, and each connecting rod allows that ground operation device can be with respect to main frame swing or vibration.
Set vibration or swing generating means preferably movably are connected on the ground operation device.This generating means can comprise and is installed in an eccentric in the rotating shaft and can be dynamically connected the connector of ground operation device to the eccentric.
This machine can also be installed the rolling of a ground connection and roll on normal direct of travel with respect to it on the main frame of the rear portion of ground operation device.
Most preferred embodiment of the present invention is described below with reference to accompanying drawings, wherein:
Fig. 1 is the lateral view of machine of the present invention;
Fig. 2 is the elevation of machine shown in Figure 1;
Fig. 3 is the plan view that is applicable to by a kind of ground operation device of machine of the present invention;
Fig. 4 is the lateral view of ground operation device shown in Figure 3;
Fig. 5 and Fig. 6 are the detailed views of a kind of mode on the main frame that ground operation device is installed to;
With reference to these accompanying drawings, machine shown in Figure 1 generally includes main frame 3, this main frame is suitable for motion and ground operation device 10 on construction ground, and this device movably is connected on the main frame, and main frame vibration relatively.This structure makes, when machine moves on construction ground, uses the vibromotive force of ground operation device 10 must cause ground to be flattened, and tamps and makes loose earth material do to distribute relatively uniformly.
The machine of shown this form is suitable for movably being connected on the motor vehicles such as resembling tractor, backhoe, so that dragged construction ground.Yet, be to be appreciated that this machine also can self install motor so that can drive on construction ground.
As shown in the figure, main frame 3 comprises linearly a casing member substantially, and this member is provided with side plate 4 and crossbeam 5, and end face and bottom surface are opening-like.Main frame 3 can adopt any suitable material to make, for example with metal etc.Ground operation device 10 is contained within the boxlike main frame 3.
Ground operation device 10 comprises a plurality of substantially parallel and phase level land scraper plates 11 across a certain distance, and these scraper plates are in the transversely extension of the normal direct of travel of machine.Every level land scraper plate 11 all includes and is suitable for the level land surperficial 12 or the limit, level land that contacts with construction ground.As shown in the figure, plane earth 12 tilts with respect to ground, so that can the guiding material following current.In addition, it also is in the plane inclined with respect to ground that these level land scraper plates are disposed in one, so that the guiding material following current.
The swing type vibration is applied on the ground operation device 10, moves back and forth so that cause this device on the direction that machine is advanced, to do usually.Install vibration generating arrangement 15, it comprises capacity eccentric bearing 16 or the axle sleeve that is connected with rotating shaft 19 work, and Zhou revolution causes bearing or axle sleeve eccentric motion like this.Connecting rod 17 movably is connected to ground operation device 10 with bearing 16.As shown in the figure, ground operation device 10 comprises level land scraper plate 11 and the framework 13 that subframe 14 is housed.This device is suspended on the main frame by a plurality of swing connecting bar 24 that are installed on trunnion 25 and 26.Each connecting rod allows that subframe 14 swings back and forth with respect to main frame 3 on the direction that machine is advanced.Another kind of scheme is that ground operation device 10 is installed on the main frame, thereby makes it realize vibration or swing with respect to sliding before and after the main frame.
As shown in the figure, rotating shaft 19 can be driven by power on the tractor and drive source, by transmission device 40 power is passed in this rotating shaft.Transmission device 40 comprises: power take-off (propeller) shaft 41, and this driver with tractor can be dynamically connected; Gear-box 42; With the belt driver 43 that comprises belt pulley 44,45 and belt 46.Should be appreciated that drive unit also is feasible scheme by being installed to that motor on this machine main frame constitutes.
Scraper plate 8 can be installed to ground connection rolling and roll on the main frame trailing edge of 7 back, so that last leveling operation is provided.
This machine also is provided with the damping unit (not drawing among the figure) that some and ground operation device and main frame can be dynamically connected.These damping units can reduce the impact to machine that caused by vibration.
At last, should understand that various selection schemes, modification and/or appendage can form different structure and layout and not break away from design of the present invention and scope.
