Description

A kind of karst soil profile digging tool

Technical field

The utility model relates to a kind of soil profile digging tool, particularly relates to a kind of assembly type instrument being specifically designed to karst soil profile and excavating.

Background technology

As everyone knows, field on-site survey and sampling and measuring are mainly taked in the investigation of pedology bound pair soil, and collecting soil sample completes mainly through fetch earth method and the soil profile method of fetching earth of earth boring auger.The earth boring auger method of fetching earth is applicable to the Karst Regional that in normality geomorphologic subregion and soil, chad content is lower, and in the soil of karst, chad content is often higher, is difficult to sample with earth boring auger, is particularly difficult to the collection carrying out deep layer soil sample.Therefore, carrying out in karst soil investigation research process, the best approach of collecting soil sample is exactly soil profile sampling method.At present, the instrument for excavating soil profile is still confined to traditional agriculture tool of production such as spade, spades, hoe.But, these instruments are suitable only for the more shallow soil profile of excavation, and for the even darker soil profile of 50-100cm, owing to being subject to the restriction of these instrument own characteristics, the soil profile space of excavating is larger, this not only can increase excacation amount, affect job schedule, also can increase section and spoir takes up an area the young crops allowance for damage expense etc. caused; When excavating section in rice terrace, because larger area destroys the plough sole in paddy field, cause paddy field to leak, soil profile excacation is difficult to the support obtaining the local common people.Although excavate soil profile by earth boring auger and conventional tool all can carry out collecting soil sample, the former is difficult to meet the needs comprehensively carrying out soil investigation in karst, and latter cost is higher, implements resistance larger.

Summary of the invention

The technical problems to be solved in the utility model is: for the defect existed in prior art, provide a kind of structure simple, be easy to carry, easy to use, lower-cost karst soil profile excavates specific purpose tool.

The technical solution of the utility model is: a kind of karst soil profile digging tool, comprise the flexible handle adopting hollow steel pipe to make, flexible handle two ends are provided with internal and external threads, flexible handle is also provided with scale, what be connected with flexible handle threaded one end is tool insert, and described tool insert comprises trapezoidal perching knife head, circular perching knife head and T-shaped mining head.

The long 500mm of flexible handle, internal diameter is 320mm, and the long 50mm of screw thread at its two ends, the scale interval on flexible handle is 100mm.

Bottom side length 60mm on trapezoidal perching knife head, go to the bottom length of side 120mm; Trapezoidal perching knife head bottom is provided with the edge of a knife, and trapezoidal perching knife head is provided with external thread short handle, the long 50mm of screw thread, the long 100mm of short handle.

Circular perching knife head is provided with external thread short handle, the long 50mm of screw thread, the long 100mm of short handle, and on circular perching knife head, side is provided with sawtooth, and opposite side and circle segments are all set to the edge of a knife.

T-shaped mining head is provided with external thread short handle, the long 50mm of screw thread, the long 100mm of short handle, and T-shaped mining head one end is tip, and one end is arrow gauge head.

In order to easy to carry, design a kit, the long 600mm of kit, wide 250mm, high 250mm, all tool fitting after dismounting can be held.

Flexible handle is made by hollow steel, and two ends are provided with screw thread, and surface is provided with scale; Trapezoidal perching knife head, circular perching knife head, T-shaped mining head are made by endurance shearing resistance high-quality steel, and its one end connects one section and is provided with externally threaded short handle; Kit can hold all tool fitting after dismounting.

Compared with the prior art, the utility model, owing to have employed technique scheme, goes for the excavation of karst varying environment Soil Under Conditions section.The degree of depth is greater than to the soil profile of 50cm, trapezoidal perching knife and circular perching knife can be utilized to complete excacation; Be the soil profile of 30-50cm for the degree of depth, T-shaped mining head and circular perching knife can be utilized to complete excacation; The degree of depth is less than to the soil profile of 30cm, T-shaped mining head can be utilized to complete excacation.Trapezoidal perching knife can not only utilize himself gravitational thrusts to excavate a certain size soil profile, not by the impact of chad in soil, and the scale on flexible handle can also be utilized to carry out depth profiled measurement and soil layer division, save and frequently use because cannot depth profiled be determined the operation that steel tape is measured.Circular perching knife directly can not only excavate section and root out the soil in section hole, and the sawtooth at its two ends and the edge of a knife can be utilized to remove the shrubbery, weeds, root system etc. that run in section mining process.T-shaped mining head is suitable for the shallow-layer excacation of more shallow section or darker section, and the larger appropriate to the occasion use tip of chad content excavates, and the less appropriate to the occasion use arrow gauge head of chad content excavates.

Meanwhile, because flexible handle can be connected with trapezoidal perching knife head, circular perching knife head, T-shaped mining head, dismantle, when trapezoidal perching knife head, circular perching knife head, T-shaped mining head can be changed after damaging in time, normal soil profile excacation can not be affected.Due to the special heterogeneity of karst height, single instrument is difficult to carry out large-area soil investigation, and this use Novel integrated considers the concrete condition of karst, devise several digging tool accessory, effectively overcome and utilize earth boring auger to fetch earth in karst and excavate problems faced in soil profile process by conventional tool.

The utility model also can be used for the excavation of Non-karst area soil profile, also can be used for other purposes, as dug Chinese herbal medicine, agricultural production etc. simultaneously.
