Abstract
The utility model provides a helical soil sampler, which comprises a variable-frequency motor, a pinion, a gear wheel, a helical drive rod, a depth positioning rod, a stop nut, a support, fixing pins and a drilling bit, wherein the variable-frequency motor comprises an output shaft; the output shaft is connected with the pinion; the pinion is meshed with the gear wheel; the gear wheel is fixedly arranged at one end part of the helical drive rod and used for driving the helical drive rod to rotate; the helical drive rod is provided with scales; the depth positioning rod is movably arranged on the helical drive rod in a sleeving manner; the stop nut is fixed on the support; the fixing pins are arranged at the two ends of the support and used for fixing the support in a soil sample; the drilling bit is detachably arranged at the bottom end of the helical drive rod. According to the helical soil sampler, by arranging the variable-frequency motor and the depth positioning rod, power is converted according to different requirements on power, variable use is performed according to the sampling depth, the degree of automation is high, and manpower is saved.
Description
Technical field
The utility model relates to soil sampling appts field, relates in particular to a kind of spiral soil sampler.
Background technology
Soil sampling technology is the important step of field soil technology for information acquisition, is one of gordian technique of precision agriculture.Generally, soil sampling analysis needs different depth soil layer sample.For example, the degree that fetches earth while probing into soil fertility is more shallow, and often needs darker soil layer sample when microorganisms existence and soil physico-chemical characteristic.The power difference that the collection of different depth needs, sampling depth also needs real-time control.In prior art, also need to not carry out power conversion and need to change the multifunction soil sampling thief using according to sampling depth according to different dynamic at present.
Utility model content
In view of above-mentioned deficiency, the utility model is necessary to provide a kind of can need to carry out power conversion and need to change the spiral soil sampler using according to sampling depth according to different dynamic.
A kind of spiral soil sampler, comprise variable-frequency motor, pinion wheel, gear wheel, spiral transmissioning rod, depth localization bar, stop nut, support, fixing pin and drill bit, described variable-frequency motor comprises output shaft, this output shaft is connected with pinion wheel, described pinion wheel engages with gear wheel, described gear wheel is fixedly installed on worm drive boom end, be used for driving spiral transmissioning rod to rotate, described spiral transmissioning rod is provided with scale, described depth localization bar is movably set on spiral transmissioning rod, described stop nut is fixed on support, described fixing pin is arranged on support two ends, for support is fixed on to sampling soil, described drill bit is detachably arranged on spiral transmissioning rod bottom.
Further, described stop nut both sides increase bayonet lock, and bayonet lock is connected with stop nut by welding manner.
Further, described stop nut arranges an alarm.
Further, on described support, soil scrapper is set, for scraping off the soil on spiral transmissioning rod periphery.
Compared to prior art, spiral soil sampler of the present utility model can be realized according to different dynamic and need to carry out power conversion and need to change use according to sampling depth by variable-frequency motor and depth localization bar are set, automaticity is high, saves manpower.
Brief description of the drawings
Fig. 1 is the spiral soil sampler overall construction design figure of the utility model preferred embodiment.
Embodiment
By describing technology contents of the present invention, structural attitude in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, the spiral soil sampler of one of the utility model preferred embodiment, for to soil sampling.This spiral soil sampler comprises variable-frequency motor 1, pinion wheel 2, gear wheel 3, spiral transmissioning rod 4, depth localization bar 5, stop nut 6, support 7, fixing pin 8 and drill bit 9.Described variable-frequency motor 1 comprises output shaft 11.This output shaft 11 is connected with pinion wheel 2.Described pinion wheel 2 engages with gear wheel 3.Described gear wheel 3 is fixedly installed on spiral transmissioning rod 4 ends, for driving spiral transmissioning rod 4 to rotate.Described spiral transmissioning rod 4 is provided with scale.Described depth localization bar 5 is movably set on spiral transmissioning rod 4.Described stop nut 6 is fixed on support.Described fixing pin 8 is arranged on support 7 two ends, for support 7 is fixed on to sampling soil.Described drill bit 9 is detachably arranged on spiral transmissioning rod 4 bottoms.
Further, described stop nut 6 both sides increase bayonet lock 61.Bayonet lock 61 is connected with stop nut 6 by welding manner.
Further, can an alarm (not shown) be set at described stop nut.In the time that depth localization bar 5 is conflicted to stop nut 6, send prompt tone, prompting staff stops continuing the down operation of brill.
Further, soil scrapper (not shown) is set on support 7, for scraping off the soil on spiral transmissioning rod 4 peripheries.
For the ease of understanding, below spiral soil sampler workflow of the present utility model is described:
First, support 7 is placed on the ground, fixed on the ground by fixing pin 8.Then as required facing to the scale regulation depth backstay 5 on spiral transmissioning rod 4, finally open variable-frequency motor 1 and drive successively pinion wheel 2 and gear wheel 3 to rotate.In the time that needs different depth is sampled, adjust different frequencies by variable-frequency motor 1 and export different power.
Spiral soil sampler of the present utility model can be realized according to different dynamic and need to carry out power conversion and need to change use according to sampling depth by variable-frequency motor 1 and depth localization bar 5 are set, and automaticity is high, saves manpower.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model instructions and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
