Abstract
The utility model belongs to the technical field of agricultural machinery and particularly relates to an actuating-cam-type no-tillage anti-clogging unit body, which mainly comprises a furrow opener, a fertilizer pipe, a cam shaft and a belt pulley, wherein the furrow opener is fixedly connected with the lower end of the fertilizer pipe and the cam shaft is a hollow belt pulley pipe. The section of the upper part of the cam shaft, which is matched with a bearing and the belt pulley, is a cylindrical section, and the remaining parts of the cam shaft are cam sections. The cam shaft is sheathed outside the fertilizer pipe. The upper end and the lower end of the fertilizer pipe stretch out of the fertilizer pipe. The bearing is fixedly connected with the upper part of the fertilizer pipe. The inner circle of the upper part of the cam shaft is fixedly connected with the outer circle of the bearing. The belt pulley is arranged above the bearing and is fixedly connected onto the fertilizer pipe. When the actuating-cam-type no-tillage anti-clogging unit body works, the cam shaft rotates at high speed under the drive of the belt pulley and can remove straw and weeds during furrowing so as to prevent the straw and the weeds from being wound and causing clogging. A no-tillage seeder which is provided with the actuating-cam-type no-tillage anti-clogging unit body can remove clogging at the front of opened furrows through the actuating cam shaft and therefore the passability of the seeder is improved. The actuating-cam-type no-tillage anti-clogging unit body is suitable for wheat and corn no-tillage seeders.
Description
Technical field
The utility model belongs to agricultural machinery technological field, particularly a kind of actuating cam formula zero-tillage anti-blocking cell cube.
Background technology
Conservation tillage be to the farmland carry out no-tillage, minimal till, cover the face of land with crops straw, reduce wind erosion, water erosion, increase soil fertility and an advanced agricultural cultivating technology of drought-resistant ability.The difficult point of exploitation no-tillage seeding machine is the through performance of machine, the ability of promptly avoiding stalk to stop up.Carry out on the northern China many faces of land that cover at the corn stubble of regional wheat no-tillage seeding of yielding two crops a year, maize straw and weeds easily are wrapped on the no-tillage seeding machine plough spade and result in blockage, make that the facility trafficability characteristic is poor, the stalk blockage problem that therefore solves the plough spade is the key of design wheat no-tillage planter.
The emphasis of no-tillage seeding machine anti-block apparatus research at present mainly concentrates on passive type and active two types.The patent No. 02287131.4 " furrowing type sower passive type winding and blocking roller device ", but this device by at the vertical transfer roller axle of plough front side configuration, thereby prevent that stalk from stopping up in plough the place ahead.But device,, very easily twines grass and stops up simultaneously owing to gapped between roller bearing and the plough the excessive no-tillage ground of stalk amount bad adaptability owing to adopt passive type anti-blocking, influences blocking-proof result.
The patent No. 200820079513.6 " drive breaking anti-blocking mechanism ", three groups of breaking facility of this mechanism rotate under the drive of transmission system, can effectively cut, broken stalk and root stubble, are beneficial to seeding operation.But this mechanism is owing to breaking of stubble breaking knife high speed and rotary tillage operation, and soil disturbance and power consumption are big, and the facility poor stability.
The utility model content
The purpose of this utility model is in order to overcome passive type and the anti-blocking shortcoming of driving type in the prior art, a kind of actuating cam formula zero-tillage anti-blocking cell cube is provided, anti-blocking cell cube mainly comprises plough 1, fertile pipe 2, camshaft 4 and belt wheel 5, it is characterized in that, camshaft 4 is a hollow pipe, camshaft 4 tops and bearing 8 and belt wheel 5 mating parts are cylindrical section, remainder is a cam segment, camshaft 4 is enclosed within outside the fertile pipe 2, fertile pipe 2 is longer than camshaft 4, all stretch out from fertilizer pipe 2 top and bottom of fertile pipe 2, and camshaft 4 internal diameters are 0.1～0.2mm with fertile pipe 2 external diameter fit clearances, the internal diameter of bearing 8 and fertile pipe 2 external diameter interference fit, bearing 8 is fixed in fertile pipe 2 tops, the external diameter of camshaft 4 top cylinder shapes part and the internal diameter interference fit of belt wheel 5, belt wheel 5 is being fixed on the bearing 8 on the cylindrical section of camshaft 4, and bearing (ball) cover 6 is fixed on the belt wheel 5 by bolt 7, the gap that spacer sleeve 3 is managed 2 bottoms covering camshaft 4 and fertile pipe 2 at fertilizer is fixed in fertile the pipe on 2, and plough 1 is fixed in fertilizer pipe 2 lower ends.
The cam segment radial height h of described camshaft 4 is 1.5～2 times of cylindrical section external diameter r.
Actuating cam formula zero-tillage anti-blocking cell cube is disposed at no-tillage seeding machine, the power of tractor is passed to gearbox by universal joint with power, give belt wheel 5 by a pair of belt wheel of gearbox side with transmission of power again, belt wheel 5 makes camshaft 4 rotate in plough trench digging process high speed, thereby hilling, crushing straw and the weeds of front side play initiatively anti-blocking effect when effectively removing the plough trench digging.
The beneficial effects of the utility model are that camshaft can be removed the foreign material such as kind of the stalk in pipe the place ahead, weeds of ditching, thereby prevent to twine and obstruction by belt wheel high speed rotating under the effect of external power; Camshaft adopts power drive anti-blocking, by adjusting the cam rotating speed, reaches better blocking-proof result; Cam sleeve has strengthened the intensity of fertile pipe on fertile pipe, reduced the materials of furrower part, has reduced cost, helps promoting the further popularization of conservation tillage.Dispose no-tillage seeding machine of the present utility model and remove the tamper in plough the place ahead, thereby improve the trafficability characteristic of sower by the actuating cam axle.
