Abstract

The denomination of the utility model is a probing spade belonging to the technical field of the underground soil sample extracting tool which primarily solves the problems due to the fact that the existing spade rod and the spade head are the fixed connection in the welding method, once the damage of the spade head happens in the using process of the probing spade, which leads to that the entire probing spade can not be used. The principal characteristic is that the probing spade contains a spade and a spade handle, wherein, the spade is composed of an upper spade pant, a middle spade rod and a lower spade head; the spade rod is movably connected with the spade head. The probing spade can be changed for a new spade head on time to continuously explore when the probing spade is damaged while in use, and has the characteristics of labor saving, time-saving and labor saving, and is a probing spade chiefly used for the soil sampling in the underground cultural relics exploration.

Description

A kind of spy shovel

Technical field

The utility model relates to a kind of instrument of underground historical relic exploration, particularly a kind of spy shovel that is used to extract underground soil sample.Belong to underground soil sample extracting tool technical field.

Background technology

Existing spy shovel all is made of shovel and shovel, and wherein, shovel is the integral body that is welded by shovel trousers made of iron, shovel bar and shovel head.Because the shovel bar is being fixedly connected of being welded with shoveling head, thereby, in the use of visiting shovel,, just cause whole spy shovel not use in case appearance shovel head damages.Its weak point is new everywhere exploration building site, except that everyone must prepare one visiting the shovel, also must prepare and somely damage and change and use in order to shovel head in investigation and prospecting visiting shovel, like this, in transportation, each side such as deposit and take care of and bring many inconvenience.And, at set intervals, collect the rear out of use spy shovel of damage, deliver in the repair shop, the shovel head is cut down, and then weld newly shovel head, like this, the cutting of shovel bar is once lacked one section, must cause shoveling bar after the replacing for several times and scrap.In addition, the height of the hoop of existing shovel head only has 1.2 centimetres, only is applicable to softer soil property soil sampling, and its weak point is in soil property situation under city or the intricately, and the hoop strength of shovel head is inadequate, in use very easily damages.

Summary of the invention

The purpose of this utility model is exactly that a kind of spy shovel that can conveniently its replacing can be continued to use when the shovel head damages is provided at above-mentioned weak point.

Technical solution of the present utility model is: a kind of spy shovel, comprise shovel and shovel, wherein shovel by the shovel trousers of upper end, the shovel bar at middle part and the shovel head of lower end and constitute, it is characterized in that: activity connects between described shovel bar and the shovel head.

Can connect by bolt between shovel bar described in the utility model technical solution and the shovel head.

Can connect by upper and lower two bolt between shovel bar described in the utility model technical solution and the shovel head.

Two bolts on the shovel bar described in the utility model technical solution penetrate one in hole can be circle, and another is oval.

The height of the hoop on the shovel head described in the utility model technical solution can be 2～2.5 centimetres.

The utility model be owing to will shovel between bar and the shovel head that the employing activity connects as bolt etc., thereby be that non-integral type detachable or that install is fixedly connected, when visiting shovel appearance in use and shovel damage, can in time lay down bolt, remove bad shovel head, more renew the shovel head, retightening bolt again gets final product, front and back also only need more than ten minute, do not go out the building site and just can finish, and can continue then to use, like this, both savings of labor saves time again, laborsaving, but also has improved work efficiency.Owing to adopt upper and lower two bolt to connect, thereby have that connection is firm, reliable characteristics between the utility model shovel bar and the shovel head.The utility model is designed to circle because the bolt that will shovel bar penetrates one in hole, and another design oval, thereby when installing and fixing shovel, can conveniently adjust a perpendicularity of shoveling.The utility model becomes 2～2.5 centimetres owing to will shovel the height design of the hoop on the head, thereby has increased the intensity of hoop, and is shock-resistant, and it is stronger to contain native power in submersible, and soil sample is difficult for taking off.The utility model is mainly used in extracting in the underground historical relic exploration spy shovel of soil sample.

Description of drawings

Fig. 1 is a structural representation of the present utility model; Fig. 2 is the structural representation of shovel bar lower end among Fig. 1.

Embodiment

As shown in Figure 1 and Figure 2.Shovel is identical with existing spy shovel with shovel trousers 21, and shovel inserts 1 in the shovel trousers 2 and fixes.Shovel is made of shovel trousers 2, shovel bar 3 and shovel 5.Shovel bar 3 lower ends forge into flat, become duckbill, and the upper and lower hole of respectively boring, upper hole 7 are circular, and lower hole 8 is oval.Shovel bar 3 upper ends connect with 2 welding of shovel trousers, and are the same with existing spy shovel.Shovel 5 be provided with two respectively with the shovel bar on the through hole of hole 7, lower hole 8 corresponding matching.During installation, will shovel bar 3 and be placed on the shovel 5, the hole connects with bolt 4 hole, adjust angle after tightening nuts get final product.The height of the hoop on the shovel 5 is 2～2.5 centimetres, increase the height of hoop after, can increase its intensity and resistance to impact, and in submersible the soil sample difficult drop-off.After adopting the utility model to visit shovel, explore the building site everywhere, each workman need only get one and visit shovel and several shovel head, by individual's keeping, in exploration operation, if damaging, can not use on the shovel head, do not go out the building site and continue to use with regard to replaceable new shovel head, very convenient.
