Abstract
The utility model relates to a forward axle of a small four wheel tractor used in agriculture, consisting of three beams, a concave trapezoid groove and a convex trapezoid groove. The three beams are in parallel and welded into a structure in a shape of 'S'; the concave trapezoid groove is arranged on the middle one of the three beams while the convex trapezoid groove is symmetrically arranged on the two beams at the two sides. The small four wheel tractor can serve 45 days by adopting the forward axle in intertillage period, shovel for three times, fertilize and spray pesticide in leaves of beans without rolling up flowers and damaging plants, which improves bean yield; fertilization is added and crops are closed during corns growth of the second and third nods, thus improving corn yield and eliminating weeds. The utility model has simple structure and convenient use.
Description
Technical field: the utility model relates to a kind of propons of agricultural small four-wheel tractor, is the improvement to existing agricultural small four-wheel tractor propons.
Background technology: existing agricultural small four-wheel tractor propons is horizontal linear; the crack, ground is too low; it can not satisfy the needs of crops shovel times three times behind crop growth; small four-wheel tractor can be liberated manpower, but can not increase production, and its reason is the intertillage phase can not reach 45 days; can only reach 30 days; crops have grown tall after 45 days, under the propons of trac. not ground, propons is bad with the plant strip that gives a discount.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of bow font small four-wheel tractor propons is provided, and has solved the northern area ridge and has made 40-45 days problem of a season crops intertillage out of reach.The purpose of this utility model is achieved in that bow font small four-wheel tractor propons by three crossbeams weldering composite bow fonts, has a spill dovetail groove in the crossbeam top of centre, is the trapezoidal convex slot of symmetry on the crossbeam of both sides, and three crossbeams are parallel.Small four-wheel tractor can reach 45 days intertillage phases shovels with this propons times three time, but soybean foliage dressing laxative, the Shandong flower does not damage plant, has improved the output of soybean, and corn is dialled joint two, three joints and is topdressed, seals ridge, has improved corn yield, has eliminated the farmland running to weeds.This product structure is simple, and is easy to use.
