Portable soil sampling apparatuses
This utility model is related to a kind of portable soil sampling apparatuses, belongs to soil sampling equipment technical field.
Soil sampling is the prerequisite that the physicochemical property to soil is analyzed.Soil sampler is adopted as pedotheque
Requisite instrument during collection, directly affects the efficiency of soil collecting.Existing soil sampler species is various, mainly may be used
It is divided into two class of mechanical sampling device and hand sampling device.Wherein, mechanical sampling device complex structure, takes up space big, and weight is big, is not easy to
Carry.Hand-operated soil sampler simple structure, it is easy to carry and carry.But either mechanical type or manual formula, are required for
Different samplers are changed in sampling process.Existing sampler is cumbersome in Renewal process, inconvenient operation, it is impossible to
Quickly fixed, wasted time and energy.

Fig. 3 is the structural representation of connecting key and keyway in this utility model.
In order that technical problem to be solved in the utility model, technical scheme and beneficial effect become more apparent, with
Lower combination drawings and Examples, are further elaborated to this utility model.It should be appreciated that concrete reality described herein
Example is applied only to explain this utility model, be not used to limit this utility model.
As shown in Figure 1 to Figure 3, portable soil sampling apparatuses, including：Handle 1, connecting rod 2 and sampler 3, sampler 3
Top be semicircular pipe, be provided with attachment means between connecting rod 2 and sampler 3, attachment means include upper links 4 and under
Portion's connecting rod 5, is provided with blind hole 6 in lower link 5, upper links 4 are inserted in blind hole 5, and upper links 4 are with connecting rod 2 integrally
Connection, and the provided circumferentially about of upper links 2 has a locating slot 7, it is corresponding, it is provided with the hole wall of blind hole 6 multiple logical
Hole 8, is provided with ball 9 in through hole 8, the outer cover of blind hole 6 is equipped with sliding sleeve 10, back-moving spring 11, top are provided with sliding sleeve 10
The outside of connecting rod 4 is provided with connecting key 16, corresponding, and keyway 12 is offered on the hole wall of blind hole 6, wherein, sliding sleeve 10
Mounting groove 13 is provided with inside, back-moving spring 11 is arranged in mounting groove 13, and the bottom of upper links 4 is provided with positioning convex 14,
11 bottom of back-moving spring is installed on positioning convex 14, and the top of upper links 4 is provided with spacing preiection 15,10 top card of sliding sleeve
It is mounted on spacing preiection 15.
When needing to change sampler, as long as by sliding sleeve slide downward, upper links are inserted in blind hole, while alignment
The position of connecting key and keyway, then unclamps sliding sleeve, in the presence of sliding over back-moving spring, ball is sticked in locating slot, real
Existing axial locking, connecting key and keyway coordinate to be realized radially locking, and is so capable of achieving fast assembling-disassembling, easy to use, effectively carries
High work efficiency.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., all should wrap in this utility model model
