A kind of arable layer depth-sampling device that the utility model proposes, it comprise sampling supervisor, piston and be connected to piston push away sample bar, piston is fitted in the storage sample tube chamber of sampling supervisor, it is characterized in that: on sampling supervisor top, rotary-cut change is installed, be fitted with rotary-cut screw rod in sampling supervisor bottom.Design feature of the present utility model is: rotary-cut screw rod can form " rotary-cut structure " in sampling supervisor bottom, it can cut off the loam core that gather in sampling supervisor bottom and loam core and former arable land soil property is separated cuts off, can take complete loam core earth sample easily out of when extracting out and sampling and be responsible for.It is performed such sampling operation: sampling supervisor gently inserts in arable soil by operating personnel, arable layer loam is entered in storage sample tube chamber successively layer by layer from sampling nozzle and forms loam core earth sample; Operating personnel rotate the rotary-cut change on sampling supervisor top again, can be collected in storage sample intraluminal loam core earth sample and former arable land soil property is separated by rotary-cut screw rod from cut-out loam core, bottom and then make; When heavily fortified point directly upwards extracts sampling supervisor out, the rotary-cut screw rod being fitted to sampling supervisor bottom effectively can also be held loam core and stop loam core to be exited in storage sample tube chamber, can guarantee that sampling supervisor takes complete loam core earth sample out of easily taking out Guan Shineng.So far, the goal of the invention that the utility model can " effectively stop loam core to be exited, improve disposable sampling success qualification rate, alleviate sampling operation labour intensity, reduce sampling operating cost " can be realized.
Furthermore, the utility model also has following technical characteristic:
The tube wall of sampling supervisor is provided with batten seam, lower batten seam.This structural design is convenient to operating personnel especially and observes the sampling depth grasped and insert in arable soil, in actual samples operation, have good result of use.
The pipe face of sampling supervisor is provided with the degree of depth and indicates chi.Its object is also to enable operating personnel grasp the sampling depth inserted in arable soil intuitively, also has certain technique effect to improving sampling work quality further.
The bottom of sampling supervisor is provided with taper inclined-plane and inserts soil structure, the outside cone angle β that soil structure is inserted on taper inclined-plane is 8 °-15 °.This structural design is convenient to insert the operation carrying out in plowland deep soil sampling especially, has the laborsaving technique effect saving time, reduce labor intensity and improve sampling operation efficiency.
The outside cone angle β that soil structure is inserted on taper inclined-plane is 12 °.Show: when being 12 ° by outside cone angle β optimal control, in actual samples operation, there is good result of use through practical probation.
The utility model compared with the existing technology comparatively has following outstanding advantage:
The utility model has initiated the arable layer depth-sampling device that one effectively can prevent " take out pipe sky and adopt phenomenon ", it is at the equipped rotary-cut screw rod with " cut-out loam core " stopping function in sampling supervisor bottom, behind insertion soil collecting loam core, only need rotate rotary-cut change from cut-out loam core, bottom, loam core and former arable land soil property can be separated by rotary-cut screw rod to cut off, when heavily fortified point directly upwards takes out pipe, rotary-cut screw rod effectively can also be held loam core and stop loam core to be exited in storage sample tube chamber, can take gathered loam core earth sample easily out of.Show through on probation: its disposable sampling success ratio is up to more than 98%, greatly can alleviate sampling operation labour intensity, improve sampling operating efficiency, the utility model compared with the existing technology has the outstanding advantages that sampling operation conveniently, laborsaving saves time, primary sample success ratio is high and reduce sampling operating cost really.
