Description
Technical field
The present invention relates to agricultural tool technical field, particularly relate to one and be applicable to wheat medium-term deep fertilizer spraying machine running resistance self-regulation furrower assembly.
Background technology
Wheat jointing to booting stage is the nitrogenous fertilizer maximal efficiency phase, therefore wheat should be tried 30% of nitrogen quantity and move on to the shooting stage and topdress, the fertilising in winter be namely commonly called as.But China's present stage, Winter wheat fertilising popularization degree is not high, and a lot of peasant does not execute or adopts 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 select to carry out in the rainy day, and therefore most peasants is selected not execute, and wheat is difficult to realize volume increase.Therefore overcome soil compaction for the fertilizer requirement providing wheat medium-term to grow simultaneously, designed and developed a one and be applicable to wheat medium-term deep fertilizer spraying machine running resistance self-regulation furrower assembly.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, when reducing deep placement wheat in winter, the damage that soil compaction causes plough, power realizes Intelligent adjustment simultaneously, energy-saving and environmental protecting, provide a kind of be applicable to wheat medium-term deep fertilizer spraying machine can the furrower assembly of Intelligent adjustment running resistance.
The present invention is achieved through the following technical solutions:
One is applicable to wheat medium-term deep fertilizer spraying machine running resistance self-regulation furrower assembly, include frame, the front end of described frame is provided with accumulator and drive motors, it is characterized in that: the left, front end 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, the below erection of described fertile case has trip(ping) lever anyhow, described trip(ping) lever is provided with three to the bevel gear engaged and a belt pulley, frame below described trip(ping) lever is 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 erection has plough, described sensor is octagonal ring sensor, gather the resistance of soil resistance reference test bar, the resistance strain gage composition Wheatstone bridge that described octagonal ring mounts, bridge voltage value is gathered by single-chip computer control system, and compare with the magnitude of voltage demarcated after amplifying process, the result collected turns back to control system for regulating the dutycycle of PWM, thus change the rotating speed of drive motors, power is sent to trip(ping) lever by belt by drive motors, by bevel gear engagement, power is passed to auger again, auger is rotated with suitable speed and loosens the soil.
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 composition 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 model calling is 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 output 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 to provide power, pollution-free, noise is little; By arranging auger in plough front end, loosening plough front knotts clay, the running resistance in the plough course of work can be reduced, extend plough and reduce soil compaction seriously to the damage that plough causes service life; The reduction of plough running resistance can impel tractor running resistance to reduce, thus reduces oil consumption.Single-chip computer control system is drag size suffered by plough, regulates the rotating speed that drive motors exports in real time, avoids the power consumption because motor speed is too fast or cause excessively slowly or plough wearing and tearing, realizes energy-saving and environmental protecting.
Accompanying drawing explanation
Fig. 1 is axis side view such as grade of the present invention.
Fig. 2 is control system block diagram of the present invention.
Embodiment
See accompanying drawing: for getting more information about this assembly, land wheel is ignored by Fig. 1 and Fig. 2.
One is applicable to wheat medium-term deep fertilizer spraying machine running resistance self-regulation furrower assembly, include sensor 11, single-chip computer control system 1, accumulator 6, drive motors 2, plough 5, auger 4, trip(ping) lever 10, sensor 11, belt pulley 9, soil resistance reference test bar 3, belt 7, bevel gear engagement 8.It is characterized in that: described wheat medium-term fertilizer distributor adopts rear-mounted hang to hang on the rear of tractor, drives these facility to move forward by tractor.Described accumulator 6 and drive motors 2 are arranged on frame front end, soil resistance reference test bar 3 is arranged on left, frame front end, sensor 10 is arranged between square steel and soil resistance reference test bar, trip(ping) lever 10 is arranged on below fertile case, trip(ping) lever is provided with three to the bevel gear 8 engaged, belt pulley 9, auger 4 is arranged on below trip(ping) lever, and plough is arranged on frame rear end.
Octagonal ring sensor is bolted between plough and square steel, and octagonal ring sensor is first manually demarcated after the installation is complete, obtains one group of relation between test force and output signal value.During facility work, soil resistance suffered by plough is delivered on octagonal ring sensor, the resistance strain gage composition Wheatstone bridge that octagonal ring mounts, single-chip computer control system Real-time Collection bridge voltage value, and compare with the magnitude of voltage demarcated after amplifying process, result turns back to control system for regulating the dutycycle of PWM, thus change the rotating speed of drive motors, power is sent to trip(ping) lever by belt by drive motors, by bevel gear engagement, power is passed to auger again, auger is rotated with suitable speed loosen the soil, thus realize the object that plough running resistance regulates automatically.
