Description

Portable powder stubble machine

The utility model belongs to the ground-working equipment that is used for farmland powder stubble, the operation of loosening the soil in the agricultural machinery.

In order to improve soil structure, recover land fertility, advocate and implemented the agronomic measures of cane and root stubble chopping and returning on the agricultural energetically.Dig stubble take a lot of work effort, the try in vain to break to pieces problem of root stubble again for alleviating manpower, realize the mechanization of root stubble chopping and returning operation, improve operating efficiency and quality, the agricultural machinery scientific and technical personnel have developed several machine for crushing stubble and feeding it into field, in agricultural production, brought into play certain effect, but also there are some problems, adopt the technical schemes such as transmission case structure of the two-stage transmission of one-level spur gear, one-level bevel gear, cause drawbacks such as complete machine structure complexity, weight is big, steel consumption is many such as Stubble cleaner.

The purpose of this utility model is exactly at the problem that exists in the prior art, design a kind of portable powder stubble machine of new structure, this machine has powder stubble, broken stubble performance and soil-loosening function well in a farming, reach the purpose of simplifying implement structure, improving transaction capabilities, conveniently use.

Basic design of the present utility model is, this machine is made up of transmission case assembly, powder stubble roller assembly and the guard shield of case type hanger bracket assembly, universal drive shaft, one-level transmission, in transmission case body, assembling a pair of being separately fixed on initiative drive shaft and the passive power transmission shaft and intermeshing driving bevel gear and passive bevel gear, the outer end of its initiative drive shaft directly is connected with universal drive shaft, the powder stubble roller assembly is fixed on the passive power transmission shaft that is positioned at the transmission case body both sides external, constitutes one-level transmission powder stubble structure; Symmetry is being fixed upper suspension arm on the top of closed frame, the two ends of upper connecting rod are hinged with upper suspension arm and case lid hanger respectively, under hang Xiao and last suspension Xiao and be packed in the closed frame bottom respectively and be configured in upper suspension arm top, constitute case type hanger bracket assembly; Powder stubble knife is sleeved on an end of handle of a knife, and sprue is installed in its outside also seam and fixes, and constitutes the powder stubble knife seam.

The utility model is compared with existing powder stubble machine, have simple in structure, labor and material saving, cheap for manufacturing cost, installation is easy to adjust, fault is few, dependable performance, characteristics that operation quality is high.
