Abstract

The utility model relates to an agricultural or building U-shaped digging machine. The machine utilizes the milling and cutting principle to dig soil. When the machine works, a tractor at an output shaft at the side tows and advances along the central line of a designed channel, the power of the tractor drives a spiral soil sampler to dig the soil through a speed reducing box, and the hydraulic power of the tractor drives the spiral soil sampler to do up-and-down action through the speed reducing box, thus adjusting the depth of a trench. The digged soil is placed at the two sides of the channel bank through a soil dividing device and a soil blocking plate, and a U-shaped channel is finished one time.

Description

Digging machine

The utility model relates to a kind of agricultural or for building U type channel trench digger.

At present, though the report of many trenching machines is arranged both at home and abroad, but be mostly the trenching machine of ladder type channel, U type channel trench digger seldom, and structurally shoveling wheel modes that adopt more, as disclosed U type channel trench digger among the patent documentation CN1058064, it is made of a frame, two wheels of cutting the earth, the ploughshare that breaks ground, a steadying plate, tail wheel, transmission system and a hydraulic system, and this trenching machine body is big, structure is not compact, cost is high.

The purpose of this utility model provide a kind of simple in structure, compact, cost is low, high efficiency, the measured a kind of U type channel trench digger that is mainly used in agricultural and builing industry of matter.

The utility model designs a kind of U type trenching machine, and this machine utilizes the milling principle to excavate soil.During work, with side output shaft, tractive force is the tractor-drawn more than 15 horsepowers, advance along design channel center line, drive the axle rotation of soil sampler through reduction box with the power of tractor, make soil up along closing sealing cover, be placed on canal bank both sides through soil distributing apparatus, breast boards branch, thereby once become canal, the excavation width be 180-190mm, trench digging speed be 100-120 rice/hour.

In addition, this U type trenching machine of the utility model design can also be regulated the ditching degree of depth, regulates trench depth by the adjusting of land wheel upper-lower position during work, and the degree of depth is a 0-0.3 rice.

The utility model comprises tractor-drawn device, reduction box, soil distributing apparatus, soil sampler and land wheel, described draw-gear be connected with described reduction box by belt, it is characterized in that: described soil sampler comprises two axles that are connected with described reduction gearbox output shaft, and its surface is provided with helical form excavation cutter; A bearing support, the one end is installed on the described axle, the other end is connected with described reduction box by fixed head, between described bearing support and described axle, be equipped with one and close sealing cover, the one end both sides of basseting at described bearing support respectively are equipped with a wing breast boards, in the front of breast boards described soil distributing apparatus is installed, described soil distributing apparatus is connected with described reduction box by transition wheel, a land wheel is equipped with in the bottom portion that fetches earth at described soil sampler, described land wheel can become 135 ° with the axle of soil sampler, fixing on two kinds of positions of 90 °, described land wheel is connected with the fixed head of an axle with the end that fetches earth of described soil sampler by a land wheel frame.

The lead angle of the excavation cutter on the soil sampler is 30 °-60 °.Advantage of the present utility model is that it can be in many grass and stony region ditchings, and will excavate, muck haulage once finishes, the canal type is neat, does not need to put in order, work quality is good again, the efficient height is simple and compact for structure, body is little, easy to operate.
