Telescopic taper appliance is connect with the synchronous pulley 13 of 12 upper end of cursor, and passes through the transmitting fortune of synchronous pulley 13 It is dynamic, arm 12, which can be relatively rotated, in second stage is turned out.Scalable taper appliance include taper appliance loop bar 16, measurement case 17, Conical rod 18, circular cone probe 19, taper appliance loop bar 16 are Hollow circular beam, and inside is furnished with harness, 16 upper end of taper appliance loop bar and same Step belt wheel 13 is fixedly connected, lower end is fixedly connected with measurement case 17, to realize guiding role.Measuring includes upper fixation in case 17 Seat 20, perforation shaft type screw rod stepper motor 21, screw rod 22, lower fixed seat 23, connecting rod 24, pressure sensor 25, conical rod 18 With circular cone probe 19.Upper fixed seat 20 is fixed by welding on measurement 17 upper surface inner wall of case, and lower fixed seat 23 is welded on survey On 17 lower surface inner wall of measuring tank, 22 upper and lower ends of screw rod are inserted into respectively in upper fixed seat 20 and lower fixed seat 23, to guarantee to pass through Screw rod 22 is fixed when shaft type screw rod 21 vertical motion of stepper motor.Penetrate through shaft type screw rod stepper motor 21 by harness with Control circuit connection in control cabinet 4, receives on control cabinet 4 by key control.Penetrate through 21 fuselage side of shaft type screw rod stepper motor Horizontal direction is welded with a connecting rod 24, which is that a rectangle hollow bar is provided with a through-hole below 24 rear end of connecting rod, It is installed on 25 electric interfaces of pressure sensor among through-hole, a through-hole is provided with above the front end of connecting rod 24, pressure passes The harness of sensor 25 is entered in connecting rod 24 by the through-hole below 24 rear end of connecting rod and is passed through above 24 front end of connecting rod Through-hole enters in taper appliance loop bar 16 and is pierced by cursor 12 into control cabinet 4, connects with the control circuit in control cabinet 4 It connects, so that detecting circular cone probe 19 gos deep into the pressure being subject to when soil.18 upper end inner wall of conical rod is provided with screw thread, with pressure sensing The connection of 25 pressure interface external connection screw of device, carries out vertical motion jointly, and 18 lower end of conical rod is fixedly connected with circular cone probe 19, the circle Cone probe 19 is designed fully according to ASAE S313.3FEB04 standard, and apex angle is 30 °, projected area 3.2cm2
As described above, control cabinet 4 presses the operation of the entire mechanism of key control by three thereon.Press first stage switch Decelerating motor in 5 control cabinet 4 of key drives Damping rotation shaft 11 to rotate, rotation of the cursor 12 around Damping rotation shaft 11, damping turn Axis 11 drives synchronous pulley 13 to rotate by synchronous belt, and the taper appliance loop bar 16 in telescopic taper appliance is around synchronous pulley 13 Rotation, whole device are in be fully deployed shape.Press the perforation axis in the telescopic taper appliance of the control control of second stage on & off switch 6 Formula screw rod stepper motor 21 moves straight down, perforation shaft type screw rod stepper motor 21 by connecting rod 24 drive conical rod 18 and Circular cone probe 19 moves together, circular cone probe injection soil, to measure cone index.It presses reset key 7 and can remove LED and show The data recorded on screen 8, and simultaneously rotate backward perforation shaft type screw rod stepper motor 21, penetrate through shaft type screw rod stepper motor 21 move straight up along screw rod 22, while circular cone probe 19 being driven to leave soil, to take multiple measurements, avoid artificial Error.
Shaft coupling used in it, nut and bolt are standard component, and switching regulator magnet base 1 is V-type magnet base, and magnetic force exists 392 or more, flexural pivot 3 is the high-accuracy multi-freedom joint flexural pivot of import, and biserial rolling element, Damping rotation shaft selection is with self-locking function "-" type rotating shaft, 14 both ends of air supporting bar are spade terminal, and single-chip microcontroller can reduce function using STM32L series Consumption, 25 selection criteria type direct lead wire output pressure transmitter of pressure sensor, perforation shaft type screw rod stepper motor 21 are selected 86mm straight line screw rod stepper motor, decelerating motor can be selected according to real work needs, therefore concrete model and specification do not have There is further progress to repeat.
Working principle of the present invention is as follows:
Switching regulator magnet base 1 is placed on vehicle body side properly to locate, vehicle can be exceeded by making cursor 12 be laid flat rear conical rod 18 The front end of body front bumper so that being convenient for measuring front does not enter the cone index on road surface, while being also considered as different vehicle Road clearance selects suitable absorption height, enables to protrude into soil certain depth, open-close type battery seat when circular cone 19 work of probe 1 power supply line is connected in the circuit of vehicle, then opens the switch of switching regulator magnet base 1, is generated magnetic force, is adsorbed on vehicle Body side, fixed position.
Level meter is placed in level meter placing groove 9, it, can be direct because being connect with switching regulator magnet base 1 by flexural pivot 3 Whether horizontal flexible rotating control cabinet 4 observes control cabinet 4 according to level meter, while installing electric power storage in cell jar 10 Pond.
It after installation steps terminate, can measure, press first stage on & off switch 5 first, start by control circuit Decelerating motor in control cabinet 4, the output shaft of decelerating motor drive Damping rotation shaft 11 to rotate by shaft coupling, make cursor 12 around Damping rotation shaft 11 rotate clockwise 90 °, and ground keeping parallelism, while by the synchronous belt inside cursor 12 makes another The synchronous pulley 13 at end is rotated by 90 ° simultaneously, and scalable taper appliance is produced from cursor 12, with ground at vertical position, gas Support rod 14 is fully withdrawn in rotary course by scalable taper appliance, and spring force reaches maximum, guarantees that scalable taper appliance is perpendicular Directly position is constant.The first stage terminates at this time, and whole device is fully deployed in work shape.
By second stage on & off switch 6, the perforation shaft type screw rod stepper motor 21 in measurement case 17 is started by control circuit, Perforation shaft type screw rod stepper motor 21 carries out vertical motion on screw rod 22, due to the connection function of connecting rod 24, conical rod 18 And circular cone pops one's head in 19 as perforation shaft type screw rod stepper motor 21 moves simultaneously, measures cone index in last injection soil, presses The pressure signal that force snesor 25 obtains is transmitted in the control circuit in control cabinet 4 by harness, after acquiring, handling Directly last cone index is shown on LED display 8, cone index herein can be read.If necessary to repeatedly survey Amount can be made to measure the perforation shaft type screw rod stepper motor 21 in case 17 and be inverted, along the upward vertical fortune of screw rod 22 by reset key 7 Dynamic, circular cone probe 19 leaves soil, while 8 number of LED display is reset, i.e. repeatable by second stage on & off switch 6 again later Operation, the cone index repeatedly measured.
