Abstract
The pneumatic seeder combined with a hydraulic motor of the utility model belongs to the pneumatic seeding machinery of the agricultural machinery. The hydraulic motor is fixedly arranged on a seeding frame, and the axis of the hydraulic motor and the axis of a draught fan are fixedly connected by a coupling. Both ends of a hydraulic oil pipe are respectively and fixedly communicated with the hydraulic motor and the hydraulic system of a tractor. The pneumatic seeder combined with a hydraulic motor adopts the pneumatic seeding operation that the rotating of a seeding draught fan is driven by the hydraulic motor so as to solve the problems of cavity and seed leakage caused by the draught fan of the seeder driven by the power output axis of the tractor when parking and starting, which eliminates the generation of the underproduction region in the rand. The pneumatic seeder combined with a hydraulic motor has the features of simple structure, stable and reliable working performance, high seeding quality and low rate of cavity and seed leakage.
Description
Technical field
The utility model belongs to the pneumatic seeder tool in the agricultural machinery.
Background technology
At present, the pneumatic seeder that in agricultural production, uses, the power resources of its blower fan rotation all are to be provided by tractor motive power output shaft, drive by universal joint, when blower fan reaches the regulation rotating speed and produces certain suction, hold seed and finish seeding operation.But, because the influence of tractor structure, when depressing clutch pedal and make clutch separation, the power take-off of tractor also stops operating simultaneously, and the rotation speed of fan of pneumatic seeder descends, and air quantity reduces, inhale incessantly kind of grain, cause the sowing hole and leak kind of a phenomenon, reduced the seeding operation quality and the strain number of keeping a full stand of seedings, form underproduction district, the edge of a field.
Summary of the invention
The purpose of this utility model is exactly at driving technical problem and the deficiency that the pneumatic seeder blower fan structure exists by tractor motive power output shaft, design provides a kind of pneumatic seeder of equipped hydraulic motor, by equipped hydraulic motor on pneumatic seeder, and, reach the purpose that improves pneumatic seeder operation quality, reduction and minimizing hole, leakage sowing rate, underproduction district, the elimination edge of a field, increases yield per unit area and economic benefit by the structure that tractor hydraulic system driving hydraulic motor drive blower fan rotates.
Basic design of the present utility model is, installs hydraulic motor at sowing frame front end on the position between sower blower fan and the tractor, utilizes shaft joint that hydraulic motor axle and blower fan axle are connected; The two ends of hydraulic oil pipe are communicated with the hydraulic system of hydraulic motor and tractor respectively, constitute the pneumatic seeder of equipped hydraulic motor.
The utility model is not subjected to the pilot control tractor to trample the influence of clutch, by the independently hydraulic motor drive sower blower fan rotation of hydraulic system driving sower of tractor, all the time guarantee blower fan stabilized (steady-state) speed under any circumstance and enough big air quantity, hole when having solved pneumatic seeder parking, starting, leakage kind of a problem, eliminated the generation in underproduction district, the edge of a field, have simple in structure, transaction capabilities is reliable and stable, seeding quality is high, hole and leakage kind rate is low, good effectiveness increases production and improves productivity.
Description of drawings
Accompanying drawing is the pneumatic seeder general structure schematic diagram of equipped hydraulic motor.
Piece number explanation among the figure:
1, sowing frame, 2, sower blower fan, 3, blower fan axle, 4, shaft joint, 5, hydraulic motor axle, 6, hydraulic motor, 7, hydraulic oil pipe, 8, tractor.
Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The pneumatic seeder of equipped hydraulic motor comprises sowing frame 1 and sower blower fan 2 mounted thereto, on the position between sower blower fan 2 and the tractor 8, install hydraulic motor 6 at sowing frame 1 front end, shaft joint 4 is installed on blower fan axle 3 terminations and hydraulic motor axle 5 terminations, and is fixedly connected with two; The two ends of hydraulic oil pipe 7 are affixed with the hydraulic system of hydraulic motor 6 and tractor 8 respectively, and oil circuit is communicated with.
When operation is used, after tractor engine starts, the hydraulic system of this machine of driving is in stable duty all the time, make hydraulic oil enter hydraulic motor 6 by hydraulic oil pipe 7 and make its rotation, make 2 rotations of sower blower fan through hydraulic motor axle 5, shaft joint 4, blower fan axle 3, produce enough big air quantity, make aspiration broadcast dish and hold kind of a grain, finish seeding operation.
