Description
Technical field
The utility model relates to a kind of seeding apparatus, especially a kind of self adaptation seeding apparatus that adapts with power set motion speed.
Background technology
In recent years, precision drilling has become the principal character and the developing direction of modern seeding technique.
The following kind of drive of the many employings of tradition sower dispenser: sower travels forward, and the land wheel that drives the frame below rotatablely moves, and land wheel drives seeder through chain or other modes and is rotated; But, perhaps often stopped up the situation that can occur skidding by earth because the ground wheel drag is big; When land wheel becomes sliding friction in the rolling friction with ground; Can accurately not drive seeder and sow synchronously, therefore can occur leaking and plant and the bad situation of sowing effect, need manual work to fill the gaps with seedlings.
In addition, because the adjusting of seeding quantity wastes time and energy normally through manual calculation and manual adjustments seeder, being difficult to increase work efficiency reaches the requirement of precision drilling.
Summary of the invention
In order to overcome above defective; The purpose of the utility model is to provide a kind of self adaptation seeding apparatus; The utility model has added the sensor that is used to detect dynamic traction device and has rotated according to speed adjustment stepper motor, thus the purpose that reaches accurate sowing, increases work efficiency.
The technical scheme of the utility model is:
A kind of self adaptation seeding apparatus comprises support, Seeding box, seeder, and support is provided with Seeding box, and the Seeding box bottom is communicated with seeder, and described seeding apparatus also includes power supply, is connected with first single-chip microcomputer, stepper motor with said power supply; Be connected with sensor, drive circuit with said first single-chip microcomputer; The other end of said drive circuit connects stepper motor; Said stepper motor output connects above-mentioned seeder, and said sensor is installed in to be cared on the seeding apparatus power set and detect the power set wheel speed.
Above-mentioned seeding apparatus; Also comprise the second singlechip system that is fixed on the power set; The sensor adopts rotary encoder and connects second singlechip; Second singlechip connects wireless launcher, and corresponding with wireless launcher have a radio receiver, and described radio receiver is connected on first single-chip microcomputer.
Above-mentioned seeding apparatus, described radio receiver and wireless launcher are bluetooth wireless devices.The beneficial effect of the utility model is embodied in:
The utility model is instead taken turns as executable operations mechanism with stepper motor, drives seeding unit and rotates, and has so just reduced land wheel and has skidded to the influence of seeding uniformity; In addition; Drag seeder with stepper motor and can pass through program means, directly parameters such as seeding quantity are provided with, easy to use and the stability of a system is good; Conscientiously ensure that seeding unit rotating disk and seeding machinary pace are synchronous, thereby improve the accuracy and the amount of broadcasting uniformity of the control of sower Precision Seeding intelligence.When the control signal drive stepping motor, stepper motor changes corner, and the continuous variation of corner is the rotating speed output of stepper motor.When the axial displacement of seeding unit was fixed as maximum or definite value, step motor drive seeding unit main shaft realized broadcasting quantitative changeization.Need during work through velocity sensor collection facility pace signal, directly to read the seeding quantity that to import on the code-disc, thereby reach the purpose of automatic control seeding unit.
Because of power set generally all are being connected with sower of detachable, and power set generally only just can be connected in the sowing process with sower, so adopts second singlechip.Second singlechip is fixed on the power set; Both adopt wireless docking mode, and the data wire of sensor is unnecessary like this extends always or be wound on the sower through power set, and convenient non-sowing time power set separate with sower; And simple in structure, reliability is high.

Fig. 2 is that the circuit module of the utility model connects sketch map.
Embodiment
As shown in Figure 1, a kind of self adaptation seeding apparatus comprises support 1, Seeding box 2, seeder 3; Support 1 is provided with Seeding box 2; Seeding box 2 bottoms are communicated with seeder 3, and described seeding apparatus also includes power supply, are connected with first single-chip microcomputer 11, stepper motor 4 with said power supply; Be connected with rotary encoder class sensor 13 with first single-chip microcomputer, be used for the drive circuit 17 of drive stepping motor; The other end of said drive circuit 17 connects stepper motor 4; Said stepper motor 4 outputs connect above-mentioned seeder 3, and said sensor 13 is installed in to be cared on the seeding apparatus power set and detect power set wheels.
Also comprise second singlechip system 12; The sensor connects second singlechip 12; Second singlechip 12 is connected with above-mentioned encoder detector 13 and wireless blue tooth emitter; Corresponding with the wireless blue tooth emitter have a wireless blue tooth receiving system, and described wireless blue tooth receiving system is connected on first single-chip microcomputer 11.
In the use; Sensor 13 is installed in power set---a side of the wheel hub of tractor, and sensor 13 detects the wheel hub walking, then signal is passed to second singlechip 12; Encode through encoder; Second singlechip 12 is transmitted to first single-chip microcomputer, 11, the first single-chip microcomputers 11 through the wireless blue tooth system and passes through drive circuit control step motor according to the information that second singlechip 12 transmits, and makes accommodation.
This shows that the utility model detects the rotational frequency of wheel hub, and according to the speed of this FREQUENCY CONTROL stepper motor, thereby the rotational frequency of control sower guarantees the uniform requirement of spacing in the rows after planting.
