Description

Colter drill

Colter drill belongs to agricultural machinery.

The sowing used of rural area at present is to articulate a single plow on 8 horsepowers of hand tractors with ploughing, and the driver walks on the ground and needs several people to cooperate just can finish simultaneously to cultivate during operation, and the slow efficient of speed is low, and labour intensity is big.

The objective of the invention is: provide a kind of a tractor serves several purposes to save the new type sowing shovel harrow that manpower reduces labor intensity.

Technical scheme of the present invention is: articulate the car body that is made of two girders and crossbeam on hand tractor headstock hitch frame, the car body tail boom is installed deflecting roller and seat.Seeding box is equipped with on the car body upper left side, and fertilizer applicator and seeder are housed respectively at the bottom of the case.Broken ridge plough is installed on the car body crossbeam of corresponding Seeding box below, circular rake foot is installed in its outside.Car body is installed ridging plough below the center, and pressure roller is installed on the right side.Seeding box broadcast fertilizer, sowing roll shaft gear is connected with a chain of clutch, another gear of clutch is connected with power gear chain on being installed in axletree.Broadcast fertile pipe sowing pipe upper end and be connected with Seeding box, the lower end places respectively before and after the circular rake foot.The plough arrow of broken ridge plough is through in the arrow cover, and the arrow cover is connected with the rotating shaft of plough eaves, and plough eaves and car body crossbeam link position are adjustable.The arrow set upper side is connected by pull bar with clutch.Ridging plough plough arrow is connected rotating shaft cylinder lever connecting rod two ends between plough arrow and its power arm with the inboard rack shaft that links to each other of car body girder.Power arm is fixed in the rotating shaft that links to each other with the control stick lower end, and the rotating shaft left end connects the pressure roller power arm.The pressure roller frame links to each other with the pressure roller power arm after having connected doff, the transmission arm of force, pull bar successively again.Unload Seeding box and broken ridge plough summer, on crossbeam, mount to weed and plough the shovel grass, ridging plough time ground earthing.Adjust brokenly the lateral separation and the depth of ridge plough and circular rake foot during operation.The driver promotes the combination of plow stick clutch forward, broken ridge, and time ditch is broadcast fertilizer, and sowing is carried out simultaneously.Pull open ridge planting behind the plow stick and stop, turning headstock control stick post-tensioning ridging plough and pressure roller and work simultaneously to finish and cover seed and press the ridge.Pushing away ridging plough before the control stick lifts together with pressure roller.The cycle alternation work like this of two ploughs.

Function total efficiency height of the present invention, a people takes driver behavior just can finish the sowing overall process.It is fertile to save artificial point, and the some seed is stepped on the ditch four-player.Be widely used in soybean, beet, the seed sowing shovel time of crops is disseminated in bar shapeds such as red bean.
