Abstract
A method for quickly replacing a powder ridge box is implemented based on the following devices: a box body, a driving motor, a spiral drill rod and a vertical lifting system. When the powder ridge box needs to be replaced, a hydraulic cylinder is started, the powder ridge box is driven to lift so that the lower end of the spiral drill rod on the powder ridge box is just in contact with the ground; a means of transport is utilized to fix the powder ridge box; a tool is adopted to unscrew and take out a bolt between a fixing part of a sliding connecting base and the box body; and after the powder ridge box is completely separated from the lifting system, the powder ridge box is replaced. A driving mechanism and the spiral drill rod for deep ploughing of soil are integrated on the powder ridge box; due to the fact that the spiral drill rod directly acts on the soil and belongs to components high in loss, the replacement frequency is high; the fixing part of the sliding connecting base is fixedly connected with the side of the powder ridge box through the bolt, the powder ridge box can be separated from a tractor only by dismantling the bolt on the side of the powder ridge box, and the goal of quickly replacing the powder ridge box is achieved.

Embodiment
Below in conjunction with Figure of description, the invention will be further described.
As shown in Figure 1, the method for a kind of quick-replaceable powder ridge case, implements based on following equipment: casing 1, drive motors 3, auger stem 4, vertical lift system 2.
As shown in Figure 1, described casing 1 is rectangle, and its inside is provided with installing space, and the top of casing 1 is portable plate; Described casing 1 side is provided with some access holes, and described access hole place is provided with access panel shutoff, when needing maintenance casing internal unit, opens access panel; Described casing two sides are along its length provided with mounting ear (sign), and described mounting ear is provided with installing hole;
As shown in Figure 1, drive motors 3, described drive motors 3 is arranged on the crown center position of casing 1, and drive motors 3 is in standing upside down, and its output shaft stretches in casing 1.
As shown in Figure 4, the arrangement in yi word pattern of multiple auger stem 4, driving rod, the flight 45 established around bull stick 41 and the cutter 42 be arranged on flight 45 that auger stem comprises bull stick 41, is connected with described bull stick 41, the direction of rotation of the flight of adjacent drill pipes is contrary, and the flight of adjacent drill pipes is interlaced.Described driving rod lower end is connected with bull stick by flange, and the upper end cover of driving rod has gear, and described gear is arranged in the installing space of casing.The width of described each position of flight 45 is consistent, passes through welding or bolt and bull stick 41 and be connected and fixed inside flight 45; The lower end of described flight 45 extends to the lower end of bull stick 41, and the upper end of flight 45 can according to its height of the depth-set of reality deep ploughing; The lower end surface of described flight 45 is inclined-plane, and flight 45 is when boring ground, and flight 45 lower end enters earth and cuts earth, is convenient to drilling rod and gos deep in earth.Described cutter 42 is fixed on the outward flange of described flight 5; Described cutter 42 comprises installation portion 423, connecting portion 422 and blade 421, and described 4 blades 21 are connected with described installation portion 423 by connecting portion 422, and described installation portion 423 is bolted on flight 45; The length being arranged on the connecting portion 422 of the cutter 42 on flight 45 from top to bottom reduces gradually, makes the global shape of drilling rod big up and small down.Described bull stick 41 lower end is provided with leg-of-mutton point of a knife 43, and the upper end of described bull stick 41 is provided with the adpting flange 44 be connected with actuating unit.By regulating the length of cutter 42 to make the global shape of drilling rod big up and small down, thus meet the designing requirement of drilling rod.Each position width of the flight 45 of this kind of drilling rod is consistent, and because the manufacturing process of cutter 42 is relatively simple, therefore drilling rod entirety manufactures simpler than the drilling rod of traditional gradual change type flight 45.As shown in Figure 5, described flight 45 is provided with the first screw, and the surface of described flight 45 is provided with the first counterbore in described first screw place.Described installation portion 423 is provided with the second screw, and the bottom surface of described installation portion 423 is provided with the second counterbore in described second screw place.Nut 48 is provided with in described second counterbore, described cutter 42 is fixed on flight 45 by bolt 47, the head of bolt 47 is collected in described first counterbore, the screw rod of bolt 47 is threaded with nut 48 through after flight 45, installation portion 423 successively, thus is locked on flight 45 by cutter 42.The end of screw rod is protruded nut 48 and is formed linkage section 49, and described linkage section 49 is provided with the protective sleeve 46 blocking nut 48 and screw rod.Described protective sleeve 46 is made up of interconnective thread bush and bulb, and thread bush is threaded with linkage section 49, bulb down and by thread bush shutoff, described thread bush and the integrated metalwork of bulb.Operationally, the extruding that flight 45 end face is subject to earth is less for flight 45, and therefore its wearing and tearing are relatively little, and the head due to bolt 47 is collected in the first counterbore and it is arranged on the end face of flight 45, so bolt 47 head is without the need to additionally protecting.Operationally, the extruding that flight 45 bottom surface is subject to earth is comparatively large, and therefore its wearing and tearing are relatively large, the bolt 47 especially protruded and nut 48 for flight 45; By arranging the second counterbore bottom cutter 42; nut 48 is collected in counterbore and nut 48 part can be protected; but because bottom the nut 48 and end of screw rod is still outside exposed; under unprotect; bottom nut 48 and screw rod end can be subject to the friction of soil and wear and tear very fast; and be subject to the invasion of soil and block nut 48, thus increasing maintenance cost and the maintenance difficulty of drilling rod.The present invention blocks the end of screw rod and the bottom of nut 48 by increasing protective sleeve 46, and make drilling rod operationally, soil can not directly contact with nut 48 with screw rod, thus protection nut 48 and bolt 47; Can be changed by the protective sleeve 46 of heavy wear, the replacing of protective sleeve 46 is relatively simple, can simplified overhauling cost and maintenance time.As shown in Figure 6, upward, the side of blade 421 is the knife back 4211 to described blade 421, and opposite side is blade 4212, and blade 4212 is towards the direction of rotation of drilling rod, and described blade 4212 is circular arc.Along flight 45 from top to bottom, the thickness of blade 421 increases gradually, and the width of blade 421 also increases gradually, and namely the intensity of blade 421 is in enhancing gradually.The different structure to cutter 42 of power suffered by each position of flight 45 is arranged; Power suffered by drilling rod lower end is greater than the power suffered by drilling rod upper end, and therefore, the thickness of blade 421 should strengthen from top to bottom gradually, thus increases the intensity being in the blade 421 of lower end, makes it be unlikely to fracture when cutting earth; In addition, cutter 42 is when cutting earth, and blade 4212 is towards the direction of rotation of drilling rod, the sharp of blade 4212 is utilized to be cut by earth, thus the earth of fragmenting bulk, blade 4212 intensity of circular arc is better, is also less likely to occur to fracture with earth head-on crash.
