Abstract
A hydraulic pressure variable value control device of corn refined sowing machine belongs to the field of agricultural machinery. For solving the problem of present corn refined sowing machines, the utility model provides a hydraulic pressure variable value control device of corn refined sowing machine whose dynamic force of variable value fertilization is supplied through a hydraulic motor. The utility model is composed of a hydraulic motor, a bearing, a fertilizer can, etc. A first chain wheel is installed on a shaft end of the hydraulic motor. The first chain wheel is connected with a second chain wheel through chains. The second chain wheel is fixedly fastened on a shaft, which is connected with a fertilizer distributor through a coupling. The hydraulic pressure variable value control device of corn refined sowing machine has simple structure and easy use. The hydraulic motor rotates with variable speed to drive a discharging fertilizer shaft to change rotational speed, thus variable value fertilizer discharging is realized by an external roller type fertilizer distributor.
Description
Technical field:
The utility model belongs to agricultural mechanical field.
Background technology:
Agriculture applied maize precise sowing machine tool has many at present, and use is the maize precise sowing machine that Wafangdian, Liaoning produces more widely, other is employed also to be this structure substantially, its fertilization system is to drive the defertilizing wheel fertilizer by land wheel through three grades of chain drive, and its shortcoming is: 1. this device can not reach real-time variable fertilization; 2. the reliability of Zhuan Zhi transmission is relatively poor; 3. because the slippage between land wheel and the ground causes defertilizing amount inaccurate.
Technology contents:
In order to address the above problem, the utility model provides the hydraulic pressure variable control device on a kind of corn Precision Seeding machine of the variable fertilising by hydraulic motor input power.
The utility model is made up of hydraulic motor, bearing, fertilizer can etc., at the axle head of hydraulic motor the one-level sprocket wheel is installed, and the one-level sprocket wheel is connected with the secondary sprocket wheel by chain, and the secondary sprocket wheel is installed with on the axle, and axle is connected with the fertilizer apparatus axle by shaft coupling.
The axle by bearing fixing on frame plate.
The hydraulic motor field calculator interior with being installed in driver's cabin is connected by power line, and the electric power of field calculator is to supply with by power supply, and the field computer peripheral equipment has tachogenerator and difference global positioner.
The utility model is simple in structure, and is easy to use.The hydraulic motor speed change is rotated and is driven the change of fertilizer expelling shaft velocity of rotation, realizes the variable fertilizer by the outer groove wheel fertilizer apparatus.Its concrete advantage is:
1. through after the repacking, machine can be realized the variable fertilization purpose according to the positional information of changeing the field, the real-time control fertilizing amount of fertilising Decision-making Expert System.
2. and adopted PFA and hydraulic-driven directly to act on, eliminated and come from the fertilizer error that tire ground is slided and caused, improved the accuracy of variable fertilization.
3. press rational application of fertilizers according to corn growth needs and soil fertility situation, improve corn yield, reduce the chemical fertilizer input, reduce production costs, reduce the pollution of chemical fertilizer environment.
Description of drawings:
Fig. 1 is hydraulic control variable device structural representation of the present utility model and is installed in structural representation on the maize precise sowing machine.
Embodiment:
The utility model is made up of hydraulic motor 3, bearing 4, fertilizer can 5 etc., axle head at hydraulic motor 3 is equipped with one-level sprocket wheel 2, one-level sprocket wheel 2 is connected with secondary sprocket wheel 8 by chain, secondary sprocket wheel 8 is installed with on the axle 1, axle 1 is connected with fertilizer apparatus axle 6 by shaft coupling 7, and the electric power of hydraulic motor 3 is supplied with by the power supply of tractor.
After hydraulic motor 3 is opened, driving one-level sprocket wheel 2 rotates, driving secondary sprocket wheel 8 by the chain that is connected with secondary sprocket wheel 8 again rotates, because secondary sprocket wheel 8 is fixedlyed connected with axle 1, therefore, axle 1 also rotates accordingly, drives fertilizer apparatus axle 6 by shaft coupling 7 again, and the fertilizer apparatus that is installed on the fertilizer apparatus axle 6 is discharged to fertilizer in the ground.
Axle 1 is fixed on the frame plate by bearing 4, prevents axle 1 disalignment when rotating.
Hydraulic motor 3 of the present utility model is connected by power line with the field calculator 10 that is installed in the driver's cabin, and the electric power of field calculator 10 is to supply with by power supply 11, and field calculator 10 is provided with tachogenerator 12 and difference global positioners 9 outward.The tachogenerator 12 that is provided with is the speeds of travel that are used for the monitoring results facility, and difference global positioner 9 is to be used for determining current plot positional information, just determine the longitude and latitude in current plot, and in field calculator 10, be inserted with the fertilising decision-making prescription map that flash card is produced, the fertilizing amount in each fritter plot of record in prescription map.Flash card in tachogenerator 12, difference global positioner 9 and the field calculator 10 makes the operator grasp the fertilising situation in each zone very easily, by the rotating speed of control field calculator 10 regulator solution pressure motors 3, thereby the amount of executing in each zone is controlled.
