Embodiment
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
A kind of excavator as shown in Figure 1 and Figure 2 excavates efficiency detection device, comprise be arranged at Hydraulic Main pump discharge place pump discharge pressure sensor, be arranged at guide's oil circuit pilot pressure sensor, be arranged at engine place engine speed sensor, be arranged at swing arm 11 places boom angle sensor, be arranged at dipper 12 places dipper obliquity sensor, be arranged at scraper bowl 13 places scraper bowl obliquity sensor, be arranged at the flowmeter of engine oil inlet pipe and be arranged at the flowmeter of engine oil return pipe, and counter and oil consumption meter; Described pump discharge pressure sensor, pilot pressure sensor, engine speed sensor, boom angle sensor, dipper obliquity sensor, scraper bowl obliquity sensor are all connected with counter input end; Described oil inlet pipe flowmeter is connected with the input end of oil consumption meter with scavenge pipe flowmeter; The output terminal of described counter and oil consumption meter is connected with Displaying Meter.
As shown in Figure 1, particularly, boom angle sensor setting is in the boom angle installation of sensors position 21 at swing arm 11 middle parts, dipper obliquity sensor is arranged at the dipper obliquity sensor installation position 22 of dipper 12 afterbodys, and scraper bowl obliquity sensor is arranged at the scraper bowl obliquity sensor installation position 23 of scraper bowl 13 afterbodys.
Wherein swing arm 11 lifting angle ranges are-49 °～73 ° (angles between swing arm two twisted points and surface level), and dipper 12 folding and unfolding angle ranges are-195 °～42 °, and it is-334 °～75 ° that scraper bowl 13 rotates angle range.
Described oil consumption meter and counter are integrated on a PCB.
As excavator, excavate the method for work of efficiency detection device, the present invention also provides a kind of excavator to excavate efficiency detection method, takes following steps:
Step is 1.: pump discharge pressure sensor detects main pump outlet pressure, pilot pressure sensor detects pilot pressure, engine speed sensor detects engine speed to be changed, boom angle sensor detects swing arm 11 liftings, dipper obliquity sensor detects dipper 12 folding and unfoldings, scraper bowl obliquity sensor detects scraper bowl 13 and rotates, and oil inlet pipe flowmeter detects oil inlet quantity, and scavenge pipe flowmeter detects recirculating oil quantity;
Step is 2.: oil consumption meter calculates whole fuel consumption according to oil inlet quantity and recirculating oil quantity; The information that counter rotates according to main pump outlet pressure, pilot pressure, engine speed variation and swing arm 11 liftings, dipper 12 folding and unfoldings, scraper bowl 13, number of times stored count are excavated in judgement;
Step is 3.: by fuel consumption with excavate number of times, calculate digging efficiency and be also shown in Displaying Meter.
Described fuel consumption meets relation: fuel consumption=oil inlet quantity-recirculating oil quantity
For step 2., particularly, general swing arm unlifting pressure is greater than swing arm falling pressure, and to invalid operations such as zero loads, when swing arm rises, main pump pressure is in 105bar left and right, and when swing arm declines, main pump pressure is in 45bar left and right; In dipper, time receiving main pump pressure is in 87bar left and right, and when dipper is put outward, main pump pressure is in 115bar left and right; In scraper bowl, time receiving main pump pressure is in 60bar left and right, and when scraper bowl is put outward, main pump pressure is in 95bar left and right.And when effective operation, main pump pressure generally continues between high pressure 150～300bar, between low pressure 100～150bar, therefore contrast is comparatively obvious, in conjunction with pilot pressure and engine speed, can easily complete the identification to working cycle.
