Electric monitor of work parameter for stable solid blending machine

The utility model is a kind of touring automatically degree of depth of mixing and stirring that detects soil stabilizer of electronic monitoring technology that adopts, and the vehicle-mounted comprehensive measurement device of travel speed and bin gate opening angle belongs to the electronic monitoring device category.

Soil stabilizer both domestic and external does not traditionally carry out the measurement of operating speed and bin gate opening angle, all adopt simple mechanical interlock scale structure and measure the method for mixing and stirring the degree of depth, check with pointer and to mix and stir the degree of depth (seeing accompanying drawing 4), need during operation manually reserve in advance to mix and stir the degree of depth and need have the special messenger to follow the lorry mounted mixer walking and mix and stir operating mode with supervision.External soil stabilizer is owing to mix and stir the construction quality height, only needs to mix and stir that can to guarantee to mix and stir the degree of depth after the depth localization constant, therefore continues to use the method that the degree of depth is mixed and stirred in the pointer measurement always.

The purpose of this utility model is to provide a kind of and not needing realizes the special messenger to monitor, can observe the lorry mounted mixer degree of depth at any time during by driver's operation, the vehicle-mounted composite monitoring device of travel speed and bin gate opening angle.Adopt this kind monitoring device accurately to measure and mix and stir the degree of depth, be convenient to driver's adjustment in time and mix and stir the degree of depth; Can accurately measure and mix and stir operating speed and calculate the operation distance, so that in time examine construction progress; Can accurately measure the bin gate opening angle, be convenient to adjust at any time the planeness that lorry mounted mixer mixes and stirs material soil.

The utility model is by the electronic gauge ［ 2 ］ that is installed in the driver's cabin, be installed in the velocity sensor ［ 1 ］ on the lorry mounted mixer output shaft of gear-box, be installed in and mix and stir depth transducer ［ 4 ］ on the lorry mounted mixer vehicle frame ［ 6 ］, the bin gate opening angle sensor ［ 10 ］ that is installed on the lorry mounted mixer bin gate ［ 11 ］ is formed.Sensor ［ 4 ］ shell body that the degree of depth is mixed and stirred in measurement is installed on the lorry mounted mixer vehicle frame ［ 6 ］, the turning cylinder ［ 14 ］ of depth transducer ［ 4 ］ is inserted in the axis hole of driven pulley ［ 3 ］ and sensor ［ 4 ］ concentric and fixing with bolt ［ 13 ］, outer rubber and pivoted housing ［ 5 ］ compression fit that increases frictional force that be with of driven pulley ［ 3 ］, lorry mounted mixer drives by support arm oil cylinder ［ 7 ］ and mixes and stirs rotor ［ 9 ］ lifting, mixing and stirring rotor ［ 9 ］, to drive big arm ［ 8 ］ and pivoted housing ［ 5 ］ be that rotate in the axle center with pivoted housing ［ 5 ］, rotate thereby drive driven pulley ［ 3 ］, the turning cylinder ［ 14 ］ of depth transducer ［ 4 ］ also rotates thereupon and exports corresponding analog signal according to the angle of rotation and is input in modulus (A/D) converter ［ V2 ］ in the electronic gauge ［ 2 ］.Central processing unit ［ V1 ］, modulus (A/D) converter ［ V2 ］, display driver ［ V3 ］, memory under program ［ V4 ］ and the bin gate opening angle unit of being made up of driver and display ［ S1 ］ are installed in the electronic gauge ［ 2 ］, mix and stir degree of depth display unit ［ S2 ］ and travel speed display unit ［ S3 ］.The analog quantity that A/D converter ［ V2 ］ will mix and stir the output of depth transducer ［ 4 ］ and bin gate opening angle sensor ［ 10 ］ converts digital quantity to and is input to central processing unit ［ V1 ］, velocity sensor ［ 1 ］ is directly inputted to pulse signal in ［ V1 ］, ［ V1 ］ is input among respective display unit ［ S1 ］, ［ S2 ］, ［ S3 ］ the Automatic Cycle detection respectively after corresponding signal being calculated the digital quantity of angle, the degree of depth, speed respectively according to the program of storage in the memory under program ［ V4 ］ by driver ［ V3 ］.

Mix and stir depth transducer ［ 4 ］ and also can be directly installed on the pivoted housing ［ 5 ］, reach with the rotation synchronously of pivoted housing ［ 5 ］ concentric and detect the purpose of mixing and stirring the degree of depth.

The operating principle that the degree of depth is mixed in the utility model measurement is:

Referring to accompanying drawing 1,2,3, when lorry mounted mixer mixes and stirs rotor ［ 9 ］ lifting by support arm oil cylinder ［ 7 ］ drive, big arm ［ 8 ］ lifting thereupon drives pivoted housing ［ 5 ］ simultaneously and rotates a certain angle, because pivoted housing ［ 5 ］ and driven pulley ［ 3 ］ compression fit, therefore driving driven pulley ［ 3 ］ rotates a certain angle, because driven pulley ［ 3 ］ is fastening with bolt ［ 13 ］ with the turning cylinder ［ 14 ］ of depth transducer ［ 4 ］, therefore the turning cylinder of sensor ［ 4 ］ also rotates a certain angle thereupon, adopts angular transducer (that is depth transducer ［ 4 ］) and according to formula

H=Lsin(90 °-α+△ α)-Lsin(90 °-α) changes angle and is converted to change in depth, thereby measure the lorry mounted mixer material soil degree of depth.α is for mixing and stirring the angle of big arm ［ 8 ］ of rotor ［ 9 ］ (before mixing and stirring operation) when ground and ground perpendicular in the formula, that is initial value, △ α is that big arm ［ 8 ］ is with mixing and stirring the angle that rotor ［ 9 ］ descends and rotates, it is variable quantity, L promptly mixes and stirs the radius of gyration of rotor for to mix and stir the axle center of rotor ［ 9 ］ and the length between pivoted housing ［ 5 ］ axle center.When mixing and stirring rotor ［ 9 ］ rotation △ α angle, pivoted housing ［ 5 ］ drives driven pulley ［ 3 ］ thereby driving angular transducer ［ 4 ］ rotates identical △ α angle.

According to identical principle, the utility model also can be with depth transducer directly with the installation of pivoted housing ［ 5 ］ concentric and must not add driven pulley ［ 3 ］, thereby easier, reliable.

The utility model adopts velocity sensor ［ 1 ］ to measure the lorry mounted mixer travel speed, measures with angular transducer ［ 10 ］ and mixes and stirs the bin gate open degree, and realize that with integrated circuit and digital display technology the Automatic Cycle of mixing and stirring operation three parameters detects.

The utility model can accurately be measured the degree of depth of mixing and stirring of lorry mounted mixer because employing is different from the diverse structure of pointer scale and utilizes electronic measurement technique.Utilize a whole set of monitoring device simultaneously, make the driver when operation, can monitor the operating speed of lorry mounted mixer at any time, mix and stir the degree of depth and bin gate opening angle, the lorry mounted mixer operating efficiency that adopts this kind device is improved and alleviates labor strength, more be adapted to the construction of high grade pavement, have good economic results in society.
