Embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is described in further detail.
Concrete structure of the present utility model and connecting relation thereof no longer are repeated in this description in order to save this section of length referring to the design of " summary of the invention " part of this specification.
The utility model selects for use dongfeng-12 hand tractor (1) to be the operation power of this ditching machine, described operation power is input to decelerator input belt wheel (11) from the diesel engine output pulley (2) of this hand tractor (1), the design gearratio is 1.6: 1, in dual output decelerator (10) inside, power is sent to two output shafts respectively.One of them output shaft and decelerator input belt wheel (11) are 90 °, design input and output gearratio is 4: 1, with this bottom and upper flange plate (7) seam, upper flange (7) is connected by flange attachment bolt (8) with the lower flange (6) that helical tooth blade makes up on (4), to helical tooth blade combination (4), make helical blade (16) realize circular motion power transmission.Another one output shaft and reducer input shaft homonymy, design input and output gearratio is 10: 1, import power into farm tractor front axle input belt wheel (14) by decelerator output pulley (12), finish dongfeng-12 hand tractor (1) reduction of speed, drive helical tooth blade combination (4) simultaneously and do rectilinear motion.During operation, helical tooth blade combination (4) only rotates earlier, and pressure and the end cutting tip downward the operator make up under the synergy of (18) and base cone (19), finish the work of boring.By observing the distance on side wing (24) and ground (3), make the degree of depth of being holed satisfy the trench digging demand.After being met the hole of demand, helical tooth blade combination (4) is moved in a circle and rectilinear motion simultaneously, sawtooth pattern is cut the outer face of native blade (17) constantly to the soil milling, the soil that downcuts is axially constantly promoting because the effect of baffle combination (5) can only be moved with helical blade, when arrival ground (3) is above, because effect of inertia, shed to the ditch side, make cutting in the trench digging process, promote, shed once and finish.Because the soil under cutting on the same cross section enters spiral simultaneously, and the bottom spiral constantly carries soil to the top spiral, for helical blade (16) is stopped up, helical blade (16) is designed to variable-pitch auger blade (concrete structure and parameter see also this specification " summary of the invention " joint).Simultaneously because the effect of side shield (25) makes relative other ditching machine of post-job furrow bank smooth.
