Abstract

The invention discloses a roller type weeding and soil loosening operation unit provided with retractable teeth, and belongs to agricultural machinery. A left end cover and a right end cover are fixedly mounted at the left end and the right end of a roller respectively, a supporting crank throw shaft is assembled in the center of the left end cover, the left side part of the supporting crank throw shaft is fixedly mounted on a positioning and supporting seat, a driving shaft is fixed in the center of the right end cover and inserted in a bearing block assembly, and a crankshaft is mounted in a central hole of the driving shaft; a retractable tooth shaft is fixedly mounted on the inner side wall surface, opposite to the crankshaft, of the crank throw shaft, located at the inner part of a cavity of the roller and sleeved with a plurality of retractable teeth, and rack parts of the plurality of retractable teeth penetrate through the side wall of the roller respectively. The roller type weeding and soil loosening operation unit solves the technical problem of winding by straw, stubble and weeds during weeding and soil loosening operation, is novel and reasonable in structure, good in operation quality, high in efficiency and wide in application range, and has few faults.

Description

The weeding of expansion teeth cylinder type is loosened the soil operation monomer

Technical field

The invention belongs to agricultural machinery, relates generally to a kind ofly to be fitted in the expansion teeth cylinder type weeding that mechanical weed and loose soil machine tool uses and to loosen the soil operation monomer.

Background technology

In order to how better production green organic agricultural product, the protection mankind's is healthy, in recent years, in China's agricultural production process, starts to advocate and promote the requirement of " three subtract " agronomic technique, the usage amount namely reducing chemical fertilizer, reduce agricultural chemicals, reduce herbicide.Therefore, the weeding by machine of intertillage crop loosen the soil operation use enter into the stage of applying in a big way.But, due to fault of construction, be no matter that traditional trailing type weeding by machine loosens the soil roller or the mechanical weeding soil-loosening roller driven by the power drive of facility land wheel or tractor outputting power, all easily produce in operation is loosened the soil by weeding by machine and the residual stalk on surface, soil, root stubble and weeds are wrapped in weeding by machine loosen the soil on roller, result in blockage, not only increase seedling-damaging ratio, reduce weeding and to loosen the soil operation effectiveness, and facility operating efficiency declines, block clearing workload increases, and labour intensity is large.Especially, when soil surface cleanness difference, the problems referred to above are more obvious, outstanding and serious.

Summary of the invention

The object of the invention is exactly for above-mentioned prior art Problems existing, in conjunction with weeding by machine loosen the soil operation use actual demand, the weeding of a kind of expansion teeth cylinder type of research and design is loosened the soil operation monomer, reach weeding loosen the soil operation time the weeding roller that loosens the soil be not wound around stalk, weeds and root stubble, do not block, improve facility operating efficiency, ensure operation quality, alleviate the object using labour intensity.

The object of the invention is achieved in that the left side at cylinder, right part is fixedly mounted with left end cap and right end cap respectively, rotating equipped support crank shaft on the centre of described left end cap, the left side of described support crank shaft is packed on positioning supports seat, the centre of described right end cap is fixedly mounted with driving shaft, be fixedly mounted with that the driving shaft of drive sprocket is rotating to be inserted on bearing block assembly, in described shaft center hole, crank axle is installed in relatively turnable inserting, on described support crank shaft and crank axle relative inner wall, be positioned at position, cylinder cylinder chamber and be fixedly mounted with expansion teeth axle, the central axis of described expansion teeth axle configures in eccentric with the central axis supporting crank shaft and crank axle, multiple expansion teeth is rotating to be successively sleeved on expansion teeth axle, the ratch portion of described multiple expansion teeth is each passed through cylinder wall, so far form the weeding of expansion teeth cylinder type to loosen the soil operation monomer.

The invention changes the traditional structure of existing integral rigidity weeding discaling roll or dish, eccentric structure is adopted to achieve the stretching motion mode of expansion teeth on cylinder, loosen the soil while operation completing intertill and clean tillage, solve again stalk, root stubble, weeds to the winding of weeding tine, there is novel structure, rationally, use the feature reliable, operation quality is good, operating efficiency is high, operation fault is few, applied widely.

Fig. 2 be in Fig. 1 A-A to cutaway view.

In figure, piece number illustrates:

1, support crank shaft, 2, positioning supports seat, 3, left end cap, 4, cylinder, 5, expansion teeth, 6, crank axle, 7, driving shaft, 8, drive sprocket, 9, bearing block assembly, 10, right end cap, 11, expansion teeth axle.

Embodiment

Below in conjunction with accompanying drawing, the invention embodiment is described in detail.The weeding of a kind of expansion teeth cylinder type is loosened the soil operation monomer, on a left side for cylinder 4, right part is fixedly mounted with respectively left end cap 3 and right end cap 10, rotating equipped support crank shaft 1 on the centre of described left end cap 3, the left side of described support crank shaft 1 is packed on positioning supports seat 2, the centre of described right end cap 10 is fixedly mounted with driving shaft 7, be fixedly mounted with that the driving shaft 7 of drive sprocket 8 is rotating to be inserted on bearing block assembly 9, in described driving shaft 7 centre bore, crank axle 6 is installed in relatively turnable inserting, at described support crank shaft 1 with on crank axle 6 relative inner wall, be positioned at position, cylinder 4 chambeies and be fixedly mounted with expansion teeth axle 11, the central axis of described expansion teeth axle 11 configures in eccentric with the central axis supporting crank shaft 1 and crank axle 6, multiple expansion teeth 5 is rotating to be successively sleeved on expansion teeth axle 11, the ratch portion of described multiple expansion teeth 5 is each passed through cylinder 4 sidewall.

During operation, outer defeated power is through drive sprocket 8, driving shaft 7 head roll 4 is at bearing block assembly 9 and support crank shaft 1 upper rotary, expansion teeth 5 is driven to rotate on expansion teeth axle 11 at cylinder 4, at support crank shaft 1 with under crank axle 6 eccentricity control, expansion teeth 5 completes relative to the radial direction of cylinder 4 and stretches out or retraction movement, when expansion teeth 5 stretches out cylinder 4 outside, complete intertill and clean tillage to loosen the soil operation, when expansion teeth 5 is retracted, under cylinder 4 sidewall coordinates, stalk on expansion teeth 5 will be wrapped in, root stubble and weeds are under strip expansion teeth 5, avoid the winding to weeding tine.
