Description
Technical field
The present invention relates to agricultural tool technical field, relate in particular to a kind of wheat deep fertilizer spraying machine in mid-term running resistance self-regulation furrower assembly that is applicable to.
Background technology
Therefore be the nitrogenous fertilizer maximal efficiency phase wheat jointing to booting stage, wheat should be tried to 30% of nitrogen amount and move on to the shooting stage and topdress, the fertilising in winter being commonly called as.But China present stage, Winter wheat fertilising popularization degree is not high, a lot of peasants do not execute or adopt the mode of spreading fertilizer over the fields, and fertilizer efficiency falls flat, and wheat is difficult to realize high yield.Trace it to its cause, winter, soil compaction was serious, if spread fertilizer over the fields chemical fertilizer, can only be chosen in the rainy day carries out, so most peasants selects not execute, and wheat is difficult to realize volume increase.Therefore for provide the fertilizer requirement of wheat growth in mid-term to overcome soil compaction simultaneously, designed and developed a a kind of wheat deep fertilizer spraying machine in mid-term running resistance self-regulation furrower assembly that is applicable to.
Summary of the invention
The object of the invention is in order to overcome deficiency of the prior art, during reduction deep placement wheat in winter, the damage that soil compaction causes plough, power is realized intelligence adjusting simultaneously, energy-saving and environmental protecting, provide a kind of furrower assembly that can intelligence regulates running resistance that is applicable to wheat deep fertilizer spraying machine in mid-term.
The present invention is achieved through the following technical solutions:
A kind of wheat deep fertilizer spraying machine in mid-term running resistance self-regulation furrower assembly that is applicable to, include frame, the front end of described frame is provided with accumulator and drive motors, it is characterized in that: the front end left of described frame is provided with soil resistance reference test bar straight down, between described soil resistance reference test bar and the frame of frame, sensor is installed, rear in described frame is provided with fertile case, trip(ping) lever is anyhow set up in the below of described fertile case, bevel gear and a belt pulley of three pairs of engagements are installed on described trip(ping) lever, in the frame of described trip(ping) lever below, be rotatablely equipped with auger, described auger bottom is provided with bevel gear, bevel gear engaged transmission on described bevel gear and trip(ping) lever, described frame rear end has set up plough, described sensor is octagonal ring sensor, gather the resistance of soil resistance reference test bar, the resistance strain gage mounting on described octagonal ring forms Wheatstone bridge, by single-chip computer control system, gather bridge voltage value, and compare with the magnitude of voltage of demarcating after amplifying processing, the result collecting turns back to control system for regulating the dutycycle of PWM, thereby change the rotating speed of drive motors, drive motors is sent to trip(ping) lever by belt by power, by bevel gear, mesh power is passed to auger again, auger is loosened the soil with suitable speed rotation.
The integrated STM8S main control module of described single-chip computer control systemization, permanent-magnet brushless DC electric machine driver module, sensor signal processing module, battery tension detection module, LCD MODULE and acousto-optic alarm module form closed-loop control system.
The input of described STM8S main control module is connected with DC-DC module, under-voltage detection module, voltage comparison module, rotor-position detection module, the input of described rotor-position detection module is successively by permanent-magnet brushless DC electric machine driver module, power tube inverter circuit module is connected to batteries, the input of described power inversion circuit module is successively by power tube prime driver module, DC-DC module is connected to batteries, the output of described STM8S main control module is connected with power tube prime driver module, LCD MODULE and acousto-optic alarm module, the input of described DC-DC module is connected with octagonal ring sensor, described octagonal ring sensor is connected to voltage comparison module by signal amplification module.
Advantage of the present invention is:
Reasonable in design of the present invention, by using accumulator and electromotor that power is provided, pollution-free, noise is little; By at plough front end, auger being set, loosening plough the place ahead knotts clay, can reduce the running resistance in the plough course of work, extends plough and reduces the damage that soil compaction seriously causes plough service life; The reduction of plough running resistance can impel tractor running resistance to reduce, thereby reduces oil consumption.Single-chip computer control system, according to the suffered drag size of plough, regulates the rotating speed of drive motors output in real time, avoids, because of motor speed is too fast or cause excessively slowly power consumption or plough wearing and tearing, realizing energy-saving and environmental protecting.
