The specific embodiment

Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, but protection domain of the present utility model is not limit by embodiment.

As shown in Figure 1 be main TV structure schematic diagram of the present utility model.The last fixed disk 19 of frame and lower fixed disk 33, by rounded cylindrical shell body 6 it is fused between the two, top, the middle part also is provided with strengthens fixed head 41,42, be the upper end that the pyramidal metal closures 11 of round platform is set in Upper shaft sleeve 14, and place the center of fixed disk 19, bottom is provided with support spring 15, the power rail 17 that the upper end of Upper shaft sleeve 14 links to each other with power source links to each other, the lower end of Upper shaft sleeve 14 places on the lower plywood of strengthening fixed head 41, its outer rolling bearing that is provided with, the upper end that gear 12 is installed in the bottom axis 23 of Upper shaft sleeve puts in the Upper shaft sleeve 14 and the projection on both sides, upper end is entered in the corresponding slideway of Upper shaft sleeve, the upper semisection of axis 23 is a screw rod, the lower semisection cross section is a square or scarce limit circle, Lower shaft sleeve 21 is sleeved on the Lower Half of axis 23, overcoat 4 is sleeved on Lower shaft sleeve 21 outsides, the lower end of axis 23 is passed the lower fixed disk 33 of frame in turn, knife rest cross bar 50 links to each other with vertical cut cutter 24 upper ends, the lower fixed disk 33 that frame is passed in the lower end of Lower shaft sleeve 21 is fixedlyed connected with knife rest cross bar 50, the two ends of knife rest cross bar 50 are hinged with an end that expands undercutting sharpener 25, one end of support link 22 is hinged with the middle part of expanding undercutting sharpener 25, and the both sides, top of the other end and vertical cut cutter 24 are hinged; The described gear 12 that is installed in Upper shaft sleeve 14 bottoms is meshed with the pinion 9 of gear shaft 7 upper ends, and the pinion 13 of coaxial lower end is meshed with internal thread gear 8 on the axis 23; The described fixed disk 19 interior edges of going up circumferentially are laid with four horizontal location pins 18, and the outer end is exposed the side face tail end and is provided with spring 34; The both sides of described lower fixed disk 33 are arranged with the alignment pin 3 that can be complementary with immersed tube bottom locating slot, and the inner of its pin is provided with spring 27, on spacer pin 32 is arranged, the outer end is provided with the iron pin 2 on band inclined-plane, top.And radially being provided with the horizontal pin 29 that can put in the draw-in groove 5 wide on Lower shaft sleeve 21 perisporiums being vertical central part with it, afterbody has spring 30 with screw 31 location, also is provided with the handle that it is pulled out on the horizontal pin 29.Described axis 23 is provided with defining flange 52 at the position of knife rest cross bar 50 following certain distances.The power source of the utility model equipment is the motor that can change anyway.

When equipment of the present utility model uses, power rail 17 is mentioned, equipment is aimed at the immersed tube mouth, and the mark that iron pin 2 is aimed on the immersed tube mouth, this mark is to aim at the immersed tube locating slot at bottom, afterwards equipment is put into immersed tube, this moment, spring 27 was compressed, and iron pin 2 presses closer the immersed tube inwall and slides downwards, directly enters the channel opening place, slip in the groove, iron pin 2 is positioned fixing.This moment, its total weight was depressed metal closures 11, and four horizontal location pins 18 are pushed outwards to be gone out, and presses closer the immersed tube inwall, and the equipment upper end is also fixedly positioning.When the power rail 17 of machining this moment turns clockwise, gear 8 puts in axis 23 downwards, vertical cut cutter 24 clockwise rotates vertically thereupon the bottom pan soil is reamed, and stops automatically after dark when reaching mark, and this moment, horizontal pin 29 stretched in the draw-in groove 5 on Lower shaft sleeve 21 perisporiums; Power rail 17 rotates counterclockwise, axis 23 begins to promote, support link 22 with outside open when will expand undercutting sharpener 25 and get out pan soil reamed, reach the design base diameter, be after power rail 17 reaches the regulation rotating speed, expand end shoveling and finish that the defining flange 52 of axis 23 lower ends contacts with knife rest cross bar 50 and stops to open at this moment, power rail 17 is rotated further a few, because the draw-in groove 5 on the Lower shaft sleeve 21 has suitable width, after a bit of distance of whole knife rest vertical-lift, stop after promptly arriving the regulation revolution, then power rail 17 counter-rotatings, the knife rest rotation is drawn in, and its gathering process is pulverized the soil body, certainly does so repeatedly, enough pulverized until the soil body, after action was finished, power rail 17 promoted, and horizontal location pin 18 moves to the center, the upper end constraint relief, iron pin 2 skids off in groove, and equipment is hung out ground, with handle horizontal pin 29 is pulled out draw-in groove 5, knife rest recovers the original shape that draws in, prepares to cut the earth next time.
