Background technique
By the end of currently, the domestic special equipment for lacking measurement root system of plant tensile strength, usually used Simple pull meter
Or Material Testing Machine tests pulling force, clamp quality is hard, rough surface due to being difficult to hold dynamics is difficult lossless clamping
With the fixed tiny root system of plant so that root system is easy to fall off or breaks at both ends, cause root system waste and efficiency it is low, be not suitable for
In the big feature of root system tension measurement operating quantity.The unilateral coaxial precision of spiral clamping device is poor, influences root system measurement accuracy.
Summary of the invention
For the problems in above-mentioned root system tension measurement, the purpose of the utility model is to provide one kind dedicated for root system drawing
Power measurement, high efficiency, high-precision mechanical device.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of suitable for the new of root system tension measurement
Type flexible fixture is made of flexible chuck, pressure sensor device, screw base three parts, and screw base includes fishbolt, spiral shell
Nail, compressed spring, duckbilled circle jaw, pedestal, stove bolt, flexible chuck includes clamping part, pedestal made of elastic material, cartridge type
Shell, cartridge type outer shell outer wall upper end are the skewed conical surface, and there are three uniform notches for extending to pedestal, pressure sensor device in surface
Including diaphragm pressure sensor, data processor, two completely identical in structure duckbilled circle jaws are by the spiral shell with compressed spring
Nail is connected, and its underpart is connected in lower layer's pedestal by stove bolt, and top and flexible chuck are connected, three resilient clamps of same size
Portion bottom surface is embedded with diaphragm pressure sensor, is fixed on cartridge type outer casing inner wall with the pedestal containing data processor.
Above-mentioned clamping part uses elastic material, it is therefore intended that clamping is avoided to cause to damage to root system.
Zigzag is made in above-mentioned clamping part surface, it is therefore intended that increases friction, convenient for fixed root system.
Above-mentioned diaphragm pressure sensor is embedded under clamping part, is fixed on cartridge type outer casing inner wall with pedestal, it is therefore an objective to convenient for control
Dynamics processed.
Above-mentioned diaphragm pressure sensor is connected with downside data processor, and when clamping force is excessive, pressure limit system is then
It gives a warning, achievees the purpose that protect root system.
Above-mentioned cartridge type shell has three uniform notches for extending to pedestal, is squeezed by duckbilled circle jaw and is uniformly collapsed, mesh
Be that reducing unilateral spiral influences the axial force of root system.
The beneficial effects of the utility model are: since fixture effectively clamps, so it is time saving and energy saving；Due to flexible chuck, pressure
The structure of force snesor, screw base three parts not only makes the tested uniform tension of root system, improves measuring efficiency, have
Effect reduces the root system extent of damage, and greatly reduces caused by unilateral screw on the influence of the axial force of root system, ensure that survey
The accuracy of fixed number evidence improves the reliability of root system measurement experiment；Present apparatus structure is simple and convenient to operate, is at low cost, is practical
Property is strong.
Detailed description of the invention
The details and application method of the utility model are further illustrated with reference to the accompanying drawing.
Fig. 1 is the positive structure schematic of the utility model.

Fig. 4 is the structural schematic diagram of sensor in the utility model.
Duckbilled justifies jaw 1, screw 2, fishbolt 3, compressed spring 4, cartridge type shell 5, pedestal 6, stove bolt 7, number in figure
According to processor 8, diaphragm pressure sensor 9, clamping part 10, pedestal 11.
Specific embodiment
As shown in Figs 1-4, a kind of novel flexible fixture suitable for the measurement of root system tension, by flexible chuck, pressure sensing
Device, screw base three parts composition, screw base include fishbolt 3, screw 2, compressed spring 4, duckbilled circle jaw 1, base
Seat 6, stove bolt 7, flexible chuck includes clamping part 10, pedestal 11 made of elastic material, cartridge type shell 5,5 outer wall of cartridge type shell
Upper end is the skewed conical surface, and there are three uniform notches for extending to pedestal 11 on surface, and pressure sensor device includes that diaphragm pressure passes
Sensor 9, data processor 8, two completely identical in structure duckbilled circle jaws 1 are connected by the screw 2 with compressed spring 4,
Lower part is connected in lower layer's pedestal 6 by stove bolt 7, and top and flexible chuck are connected, three 10 bottoms of resilient clamp portion of same size
Face is embedded with diaphragm pressure sensor 9, is fixed on 5 inner wall of cartridge type shell with the pedestal 11 containing data processor 8.
Before use, root system of plant one end to be measured is put into collet, fishbolt 3, compressed spring 4, to cartridge type shell 5 are rotated
Pressure, so that 10 stress of resilient clamp portion on inner wall gathers clamping root system, diaphragm pressure sensor 9 to shift to an earlier date and data processing
Device 8 and the connection of the data display equipment of outside, diaphragm pressure sensor 9 transmits data, root because being pressed to data processor 8 at this time
