Embodiment
In order to more fully understand the purpose of this utility model, technical scheme and advantage, below in conjunction with the accompanying drawings and embodiment pair The utility model is further described, but not as to limitation of the present utility model.
It is as Figure 1-3 a kind of specific embodiment of the soil sampler provided, the soil sampler can be applied to agricultural land soil and take Sample, it is applicable to a variety of farmlands such as paddy field, nonirrigated farmland.The soil sampler includes:Drill bit 20 and the drilling rod 10 for hand-held, institute Drill bit 20 is stated as a tubular structure with inner chamber 23, the front end of the drill bit 20 is to tunnel structure, the rear end of the drill bit 20 Be fixedly connected with the drilling rod 10, the drill bit inner chamber 23 is fetched earth earth for pick, the tail end of drilling rod 10 be additionally provided with handle 15 with It is easy to hold.
In the present embodiment, the diameter of drill bit may be selected to be 15-20cm, and the highly preferred of drill bit is 20-30cm, makes drill bit can Get appropriate soil.Meanwhile the length of drilling rod 10 is more than 100cm, while being easy to hand-held, can also be deep into suitable Depth is fetched earth.
In the present embodiment, the driving structure is to be arranged on the tooth-shape structure 21 of the front end of drill bit 20, tooth-shape structure 21 contribute to drill bit 20 to go deep into soil, effectively reduce the penetration resistance of soil sampler.
In the present embodiment, the perisporium of drill bit 20 of the tubular structure is additionally provided with helicla flute 22, so, when fetching earth, It can be goed deep into by the rotary of drill bit 20, loosen the soil body using helicla flute 22 so that the process that drill bit 20 enters the soil body is more held Easily.
As further improvement of this embodiment, the afterbody in the inner chamber 23 is additionally provided with one and can moved down along inner chamber 23 The dynamic push pedal 27 for being used to release soil, and the driving structure being connected with the push pedal 27.The driving structure includes one and institute The push rod 28 of the connection of push pedal 27 is stated, the push rod 28 stretches out the rear end of the drill bit 20 so that push rod 28 can promote the push pedal 27 move up and down in the lumen.As a kind of embodiment, push rod 28 can be arranged in parallel with drilling rod 10, when drill bit 20 takes out soil When, drive push rod to promote the push pedal 27 that soil is released into inner chamber 23 downwards, to obtain more complete undisturbed soil.So, no Be implemented only in disturbance it is less in the case of fetched earth, and can soil be taken out from inner chamber 23 more conveniently.
In the present embodiment, the shaft of drilling rod 10 is additionally provided with axially extending axle grooving 16 and connected with the endoporus 11 It is logical, the tail end of the push rod 28 is provided with leader 12 and is used to promote the push rod 28, the handle 12 is cut through the axle Groove 16 is attached with the push rod 28, and the handle 12 can act on lower axle in the length range of the axle grooving 16 in external force To movement, the push rod 28 can move axially along the endoporus 11 of the drilling rod 10 under the promotion of the handle 12.So, may be used Push rod 28 is limited using endoporus 11, makes the pushing course of push rod 28 more stable, simultaneously because push rod 28 is arranged on brill It is separately provided in bar rather than outside drilling rod, also maintains the compactedness of sampler structure.Wherein, the setting of handle 12 is to utilize It is moved axially along axle grooving 16 during Manual-pushing handle, so as to drive coupled push rod 28 to be slided in endoporus 11, And then drive push pedal 27 to be moved in the inner chamber of drill bit, after soil is got in drill bit inner chamber 23, promote handle 12 can be by soil Released from inner chamber 23, and then obtain complete soil block.
In the present embodiment, the tail end of the endoporus 11 is additionally provided with a transection slot 13, the transection slot 13 and the axle Grooving 16 is vertically arranged, and the handle 12 can rotate in the transection slot 13 to limit the push rod 28 in the endoporus 11 Slide.That is, when without using push rod 28, can be turned in transection slot 13, and need when needing to use by Soil is produced when being released from inner chamber 23.Meanwhile when push rod 28 is gone in transection slot 13, handle 12 can also be ridden Being used in when fetching earth for plate provides strength of one's legs support.Certainly, it is used to provide strength of one's legs support as shown in figure 4, can also be separately provided foot-operated 17.
In addition, for the present embodiment, to improve the portability of soil sampler, the drilling rod 10 of soil sampler comprises at least two sections It can be connected with each other and dismountable connecting rod, the length of drilling rod can be increased in order to operate by the connection of these connecting rods, simultaneously The space-consuming of soil sampler can be reduced during dismounting in order to carry.Such as with shown in Fig. 1, using the soil sampler that the present embodiment provides as Example, drilling rod 10 can be divided into two can be connected with each other and dismountable connecting rod, junction 14 may be disposed at 40cm, connection Mode can use threaded connection or the mode such as snap connection.
In the present embodiment, scale is additionally provided with the drilling rod 10, for agricultural land soil collection, scale size can 0~100cm distance is designed as, is easy to control the depth of soil collection, realizes that it is that layering can be achieved to adopt not have to dig soil profile Collect soil sample.By taking the present embodiment as an example, 40cm, 60cm, 80cm and 100cm can be set in the setting of scale, to meet daily take Native demand.
In the present embodiment, the drill bit 20 of soil sampler can use stainless steel, and it has, and antirust ability is good and hardness is high Effect, it is possible to increase the durability of soil sampler.And for drilling rod 10, particularly, can for the drilling rod of removable section Using material lighter alloy or plastics, in order to carry.
In use, handle 12 first to be rotated into the position of transection slot 13, so as to be in drill bit inner chamber 23 last for push pedal 27 End position, drill bit 20 is directed at the soil for needing to sample and drilled down to by hand-held handle 15, while described can be slammed by strength of one's legs Hand 12 (uses) when handle can also be used as foot-operated, or if when being separately provided with foot-operated (as shown in Figure 4) can slam it is foot-operated Under causing drill bit in depth, after in depth getting soil down, drill bit 20 is taken out, now by handle 12 from the position of transection slot 13 Back-out is put, and enforcing handle 12 makes it be slided on axle grooving 16, so as to drive push rod 28 to be slided in endoporus 11, push rod 28 promote push pedal 27 to release soil from the inner chamber 23 of drill bit 20 again, so as to obtain complete soil shape.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
