The steps of using a domestic small garden tamper herein are described in detail with reference to figures 1 to 7: in the initial state, the winding wheel 23 winds the lifting belt 24 to enable the lifting plate 16 to be in the upper limit position, the boosting spring 25 pulls the large ramming earth plate 26 to enable the large ramming earth plate 26 to be in the upper limit position, the earth discharging plate 36 is in the front limit position, the protruding end of the centrifugal wheel 71 faces downwards, the fixing rod 73 is in the upper limit position in the lifting groove 72, the control motor 37 is in the front limit position, and the threaded sleeve 50 and the second translation gear 53 are in the front limit position.

When preliminary ramming earth, start winding motor 74, winding motor 74 drives belt wheel 23 and rotates anticlockwise under the circumstances, and then makes lifter plate 16 descend fast, and when lifter plate 16 descends to lower extreme position, helping hand spring 25 further promotes big board 26 of ramming earth and descends, tamps the soil heap for the first time and makes the surface level relatively, and reverse fixture block connecting rod spout 21 makes lifter plate 16 rise to upper extreme position and draws back big board 26 of ramming earth through helping hand spring 25.

During fine machining, the control motor 37 is started, the control motor 37 shifts the gear of the power rotating shaft 67 to rotate to drive the centrifugal wheel 71 to rotate, when the protruding end of the centrifugal wheel 71 rotates to the upper limit position, the fixing rod 73 slides to the upper limit position in the lifting groove 72, the control block 38 ascends to the upper limit position and pushes the rack 68 through the arc gear 69, so that the small rammed earth plate 28 is located at the upper limit position, when the protruding end of the centrifugal wheel 71 rotates to the rear limit position, the control block 38 generates an inclination angle, the arc gear 69 moves the small plate connecting rod 29 backwards through gear tooth engagement with the rack 68, when the protruding end of the centrifugal wheel 71 rotates to the rear limit position, the arc gear 69 is separated from the rack 68 and puts down the small plate connecting rod 29, the small plate connecting rod 29 loses the supporting force of the lower end face, the small rammed earth plate 28 further tamps earth pile through self gravity, and at the same time, the worm 39 drives the worm wheel 49 on the lower side to rotate through meshing, the worm wheel 49 drives the threaded sleeve 50 to rotate and move backwards on the motor translation screw 51, the threaded sleeve 50 drives the first translation gear 52 to rotate, the first translation gear 52 drives the second translation gear 53 to slide and rotate on the belt driving rotating shaft 54 through gear teeth, the belt driving rotating shaft 54 drives the driving pulley 55 to rotate, the driving pulley 55 drives the first driven pulley 56 and the second driven pulley 58 to rotate through the first belt 57, the second driven pulley 58 drives the third driven pulley 59 to rotate through the soil inlet 60, and further drives the control block translation screw 42 and the fixed rod translation screw 44 to rotate, the control block translation screw 42 and the fixed rod translation screw 44 make the second translation block 43 and the first translation block 41 move backwards synchronously through threads, the first translation block 41 drives the control motor 37 to move backwards, the worm 39 is always engaged with the worm wheel 49, and when the small ramming earth plate 28 presses the earth pile, the control motor 37 is reversed, the ramming is performed again and returns to the initial position, and the retractable door 64 is manually opened to take away the earth pile stacked on the earth discharging plate 36.

The invention has the beneficial effects that: the invention uses the big plate to tamp the soil pile primarily and then uses the small plate to tamp the soil pile further by changing the pressure, because the surface area of the small plate is far smaller than that of the big plate, the secondary tamping effect is far higher than that of the primary tamping, and the device can take out the tamped soil pile without detaching the wood plate, thereby avoiding the trouble of reinstallation. In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
