Embodiment
Embodiment mono-
The present embodiment is a kind of and blue or green green soy bean picking machine (is prior art, the Chinese patent that its concrete structure can be 201320588756.3 referring to application number, also can apply on other type, the disclosed reaping machine of Chinese patent application that for example application number is 201310476512.0) supporting survey product device, basic comprising as shown in Figure 5, comprise the controller 1 that contains data memory module 17 and display module 16, also comprise that signal output part connects respectively yield meter quantity sensor 3 and the wheel speed sensor 4 of controller 1 central processing unit 14 corresponding ports.This central processing unit is inputted by keyboard input module 15, and its alarm signal output ends is connected with warning device 2, is powered by power supply 18.
As depicted in figs. 1 and 2, controller 1 and warning device 2 thereof are placed in the handrail below of reaping machine, the support arm 22 for laying collecting box 6 is equipped with in the below of harvesting apparatus 21 outputs of these reaping machine frame 20 front portions, one end of this support arm 22 is fixed in frame 20 by trivet, the other end is the cantilever-shaped section of stretching out, the middle part upper surface of this section of stretching out is installed the weight sensor as yield meter quantity sensor 3 of bearing collecting box 6, the lower end that outer end is connected in the vertical suspension rod 25 on handrail by horizontally extending elongated slot and upper end is connected, like this can be by elongated slot, take the circumstances into consideration suitably to regulate wheel relative position, make it near machine gravity, thereby it is more reliable and more stable to ensure to survey product work.
As concrete the installation as shown in Figure 4 of weight sensor of yield meter quantity sensor 3, its bottom, one end is fixed on the support angle steel 26 being connected with support arm 22, other end top and load-bearing angle steel 23 are connected, the center of gravity of collecting box 6 is carried on load-bearing angle steel 23, the bottom surface of collecting box 6 is higher than support arm 22 upper surfaces, thereby formation meets the cantilevered support structure of weighing and sensing requirement.
Support arm 22 is born the upper surface of collecting box 6 weight sensor as yield meter quantity sensor 3 is installed.The gearbox 10 that the top of frame 20 settles power set to drive, the output shaft 8 of this gearbox drives axletree 7 by chain drive 9 with the speed ratio of 1:1, therefore the wheel speed sensor 4 that directly reflects vehicle wheel rotational speed can be placed in to output shaft 8 places.As shown in Figure 3, this wheel speed sensor 4 comprises that arrangement is fixedly distributed on four Nd-Fe-B magnet steels 12 on coaxial disc 11 edges on reaping machine output shaft of gear-box 8, and the Hall element 24 of the outside corresponding disk cylindrical position arrangement of the contiguous output shaft 8 of gearbox, between the two apart from being controlled at 8-11mm scope.The signal output of this Hall element 24 connects the corresponding ports of central processing unit 14 as the signal output part of wheel speed sensor 4.
In circuit theory shown in Fig. 6, U3 and peripheral components thereof form power circuit, DS1 is the display module being connected with central processing element U1 corresponding ports, J6, J7, J8 and J10 are connected respectively three LOAD CELLSs (also can only adopt) and Hall element with central processing element U1 corresponding ports, J5 is alarm lamp, J11 is approach switch, P3 is AD module, and SW1 is preservation information key, and P5 can connect SD module for storage.
When work, first according to the actual plantation situation of blue or green green soy bean, input leading value and check input by display module 16 by keyboard input module 15, after confirmation, the handle of operative clutch 13 is moved to the one side that makes picking machine work, now be positioned at approach switch 5 closures of this handle working end, control survey product device and start to gather each sensor signal; Meanwhile, handle Traction clutch 19 handles one end to picking machine walking, that realizes machine walks to pluck operation certainly.When monoblock beans field gathers in the crops when complete, operation Traction clutch 19 handles, to one end that picking machine stops, being controlled and are shut down, then operative clutch 13 handles are resetted, and approach switch 5 returns to normally open, controls system for measuring yield and finishes to gather each sensor signal.After machine comes to a complete stop, storage sensor record to should number field area and the final data of yield values.After this, the blue or green green soy bean of plucking is unloaded, change field and repeat above work, its data save as next field number.In this process, if when the weight of collecting box 6 interior blue or green green soy beans reaches default threshold value, the alarm lamp of warning device 2 is glittering and sound a buzzer, and prompting is unloaded and plucked the blue or green green soy bean of adopting or change empty collecting box.
Be summed up, the present embodiment has following features:
1) yield meter quantity sensor adopts cantilever to install, and is fixed on the below of picking machine rear portion collecting box, can the blue or green green soy bean output of real-time online measuring.And default the higher limit of output, both prevented that yield meter quantity sensor from stressedly excessively causing flexural deformation, extending its service life, prevented that again in collecting box, blue or green green soy bean overfill is overflowed.When reaching threshold value, the weight of blue or green green soy bean in collecting box gets final product alarm.
2) wheel speed sensor is used for the revolution n of axletree in the analytical unit time, be radius of wheel by formula v=2 π rn(r) converting obtains the speed of travel value of picking machine, be the working time by formula s=vtd(t again, d is leading value) calculate harvesting size.Because picking machine operating environment is severe, if sensor 4 is fixed near axletree 7, be easily subject to the impacts such as distortion, clay contaminated of jolting, and above-mentioned interference obviously can be avoided in the installation site of the present embodiment, is conducive to ensure certainty of measurement, and easy for installation.And error is counted in the survey producing can effectively reduce the discontented circle of picking machine vehicle wheel rotation in the time of farm work time that arranges of 4 magnet steel.
3) controller, taking central processing element as core, can gather the signal that merges each sensor, and the output that calculates rapidly blue or green green soy bean in respective regions distributes; Memory module adopts SD card, can store all data that record, and conveniently data is carried out subsequent treatment, is drawn output distribution map etc.
4) work that adopts approach switch 5 to control survey product device can be played the effect to its protection.
5) adopt central processing element SCM system and the storage of SD card, cost and energy consumption are all very low, and simplicity of design, reliability are high, have met the Liquified gas tanker of precision agriculture production.
