Description

The high net picking rate cylinder-suction-type self-propelled cotton picker

One, technical field: high net picking rate cylinder barrel aspiration self propelled cotton picker of the present utility model belongs to the agricultural machinery field.

Two, summary of the invention: according to the retrieval, only the cotton picker patent application of Xinjiang proposition promptly reaches 67 more than, and majority is the air-sucking type cotton picker, and for example the patent No. is 200520008820.1, and denomination of invention is wherein typical case's representative for the patent of " economic benefits and social benefits point contact type cotton picker ".It is adopted the hand-held cotton suction duct of cotton people velveteen is aspirated by the Diesel Driven air pump, and defective is that the air-flow in the cotton suction duct is in aspiration phases all the time, has also aspirated the branches and leaves fragment that dries up on the cotton plant in the suction velveteen; Though this machine has been installed the branches and leaves removal device, effect is unsatisfactory, and the reduction of velveteen grade directly influences the cotton dress income.For velveteen is siphoned away from the boll hull brute force fully, the suction force of required wind is just bigger, has determined the more powerful diesel engine of necessary use, thereby makes oil consumption, noise strengthen, and machine is adopted cost and remained basically stable even exceed with artificial the harvesting, and the cotton grower can't bear.

The purpose of this utility model is to propose a kind of the driving by light duty diesel engine and produces powerful suction force, the cylinder barrel aspiration self propelled cotton picker that pick up rate is high.

The purpose of this utility model is achieved in that installing collection hopper, frame and diesel engine on the chassis, and this machine drives driving wheel, idler, driven big belt pulley, crank, connecting rod, vertical swing arm in proper order.Frame lower is installed two cylinders, and each is communicated with installing mouthpiece and suction tracheae its closed at both ends.The piston rod of installing piston and being attached thereto in the cylinder, this bar outer end links to each other with a swing arm is active respectively.The frame top is equiped with four and covers the wind device, connects the dress negative-pressure air valve on its upper surface; Connect on the lower surface and take on cotton valve and cotton-feeding pipe, this pipe other end with collect hopper and be communicated with; Connect dress on the sidewall and inhale cotton valve and cotton suction duct.The other end of four suction tracheaes is communicated with respectively with in the chamber of covering the wind device.Frame the place ahead installing control gas pedal, it links to each other in proper order with vertical depression bar, backguy, negative-pressure air valve inwall.Be equiped with differential mechanism on the frame below the chassis, its power transmission shaft outer end company adorns hydraulic motor, in the power take-off company of diesel engine gear pump, this pump and hydraulic motor interlock is housed.The differential shaft of differential mechanism both sides links to each other in proper order with universal joint, power transmission shaft respectively, and power transmission shaft other end installing sprocket wheel connects the dress driven wheel on the front-wheel hub, and sprocket wheel links to each other with chain with driven wheel.

Owing to implement technique scheme, this cotton picker can adopt light duty diesel engine to drive steam-cylinder piston and move back and forth, and produces powerful suction airflow.When walking certainly, adopt cotton people and be sitting on the chair and hand-heldly adopt cotton pin control control gas pedal, adopt the cotton mouth of pipe and aim at the velveteen suction, avoided sucking withered branches and leaves fragment, guaranteed pick up rate, reduced and adopted cotton cost, alleviated labour intensity.
