Sensor comprises strain beam that is arranged on two ends and the transducer that is fixed on the beam, one end strain beam is by on the housing that is bolted to tester, other end strain beam is provided with the screw that is positioned on the center sensor line, and the rear end of probe is provided with screw thread and is connected with strain beam by screw.
The locus of location-plate and the direction of motion of probe are perpendicular, also are provided with location scale and locating clip on location-plate, and locating clip is fixed on the clamping plate that can move along the location scale.
Locating clip and clamping plate by screw retention on location-plate.
Because probe is fixed on the strain beam of sensor, when probe promotes cane, its pressure is by the processing of circuit such as sensor, Single Chip Microcomputer (SCM) system, convert force signal to electric signal, the maximum pressure that cane is born under ultimate limit state shows on display with digital form, very intuitive and convenient.Location-plate on its support can be measured the buckling resistance of cane at the differing heights place.The utility model adopts battery supply, and volume is little, and is simple to operate, can carry out somatometry to cane in each stage of plant growth, and then according to the buckling resistance of stem fiber layer and the correlativity of lodging tolerance colony's measurement data carried out statistical treatment.

Embodiment
The utility model comprises support 1 and the tester that is contained on the support, is provided with probe 6 in the working end of tester, is provided with location-plate 9 in the handheld terminal and the probe 6 corresponding positions of support 1.Described tester also comprises housing 2, be arranged on display 7 and the button 8 on the housing 2 and be contained in sensor 12, circuit board 13 and battery 14 in the housing 2, and circuit board 13 is provided with Single Chip Microcomputer (SCM) system and power supply chip.Battery 14 is 9 volts of packed cells of single-unit, and battery 14 is connected with Single Chip Microcomputer (SCM) system with sensor 12 respectively with power supply chip by lead, and sensor 12 is connected with Single Chip Microcomputer (SCM) system by lead, and Single Chip Microcomputer (SCM) system is connected with button 8 with display 7 by lead.Power supply chip plays the effect of voltage stabilizing and switch, and after finishing the pressing time of setting, chip promptly interrupts being connected of chip and sensor under the control of single-chip microcomputer; When instrument was not worked for a long time under open state, chip can cut off the power supply automatically to save battery.In the present embodiment, sensor 12 employing models are the semiconductor strain formula sensor of CLAS-50N.The primary structure of sensor 12 is to be arranged on the strain beam at two ends and to stick on the force-electricity energy converter of being made up of semiconductor gauge on the beam.The strain beam of one end is by being bolted to the housing inner chamber of tester, the strain beam of the other end is provided with the screw that is positioned on the center sensor line, probe 6 rear end is provided with the screw thread that matches with screw, and probe 6 is fixedlyed connected with sensor 12 by the screw on the strain beam.The front end of probe 6 stretches out outside the housing 2, also is provided with and can pitches 4 to the spy that cane plays the role of positioning at its front end face, and visiting fork 4 is fork sheets of an arc, is fixed on the axle head of probe 6 by screw or rivet.Except such scheme, also can pop one's head in and be set to cooperating between plain shaft, the hole, with screw or pin location with the connected mode of sensor; Also can between axle, hole, adopt press fit.
The effect of location-plate 9 is to support and fixing crop cane.Because test is the axial buckling resistance of stem fiber, therefore the locus of location-plate 9 be set to and 6 the direction of motion of popping one's head in perpendicular.Again because the cane of rape plant is thinner, can fix the crop cane in order to test, on location-plate 9, be provided with locating clip 5, the stem of plant bar cramp is locating clip 5 in and also perpendicular with 6 the direction of motion of popping one's head in.In order to measure the buckling resistance of cane, on location-plate 9, also be provided with and locate scale and can be longitudinally along the location clamping plate 3 that move of scale at differing heights place fiber.In the present embodiment, be provided with guide groove 11 with the corresponding length of location scale, screw 10 passes guide groove 11 and can move along guide groove, locating clip 5 is connected with location-plate 9 by screw 10 with clamping plate 3, unclamp screw 10 when need adjusting the test height of cane and move clamping plate 3, and then tighten screw clamping plate 3 are fixed on the location-plate 9 to desired location.In addition, also can be separately with locating clip 5 by screw, rivet or be adhesively fixed on the clamping plate 3.Can also rail groove be set in clamping plate 3 both sides location-plate 9 is placed in the groove, pass through screw retention; Or on location-plate 9, T-slot is set, by bolt clamping plate 3 are connected with location-plate 9.
In order to support tester, be provided with and the perpendicular groove in location-plate 9 positions at the support end of support 1, the housing 2 of tester is placed in the groove and can be slidingly matched with groove.Can exert pressure by the 6 pairs of canes of popping one's head in hand propelled housing 2, till irreversible folding line appears in the fibrage of crop cane, probe 6 passes to the pressure that bears on the strain beam of sensor 12, convert force signal to electric signal by transducer, Single Chip Microcomputer (SCM) system converts analog signals to digital quantity signal and send segmentation digital liquid crystal display displays, thereby cane suffered maximum pressure under ultimate limit state is read on display with digital form.Can carry out statistical treatment to measurement data according to the buckling resistance of stem fiber layer and the correlativity of lodging tolerance at last.This device also is applicable to other and the similar thin bar crop of rape cane.
