Abstract
The utility model relates to a probe for measuring temperature and moisture of soil, comprising an inner protective sleeve with ventholes, a moisture sensitive element and a converting circuit. The moisture sensitive element and the converting circuit are arranged in the inner protective sleeve, and the outer part of the inner protective sleeve is sheathed with an outer protective sleeve. A spring bolt is arranged on the inner protective sleeve, and is matched with an upper position-limiting hole and a lower position-limiting hole of the outer protective sleeve. The front end of the inner protective sleeve is a cone head, and the back end is connected with a handle. The back end of the outer protective sleeve is connected with a pull handle. The probe can effectively prevent ventholes in the protective sleeves of soil from being blocked. The use is convenient, and the measuring is exact.
Description
The utility model belongs to temperature and humidity measurement apparatus part field, is specifically related to a kind of probe of measuring temperature, humidity.
The humidity of measured soil, temperature, for agricultural, particularly thin dish plant husbandry is significant.Employed in the past thermometer, hygrometer are unsuitable for the measurement of the soil moisture, humidity.Because the measurement of soil moisture, temperature must place the probe of hygrometer, thermometer the soil of measured humidity, temperature, allow the soft air in the soil surround humidity-sensitive element, therefore, on the protective sleeve that humidity-sensitive element adds, leave some air holes.When thermometer, hygroscopic probe injected or extract soil, air hole was easily blocked, and perhaps the clay contaminated humidity-sensitive element influences the accuracy of measuring, and is inconvenient to use.
The purpose of this utility model is to provide a kind of probe that is suitable for measured soil temperature, humidity, and is not only easy to use, and can prevent the obstruction of earth to the protective sleeve air hole effectively.
The technical solution of the utility model is as follows:
A kind of probe that is used for measured soil humidity, temperature, comprise the internal protective cover that has air hole and humidity-sensitive element, change-over circuit, humidity-sensitive element, change-over circuit place in the internal protective cover, the internal protective cover outside is with outer jointing jacket, and the spring hitch on the internal protective cover matches with upper limit hole, the lower limit hole of outer jointing jacket; The internal protective cover front end is tapered; The internal protective cover rear end is connected to handle; The outer jointing jacket rear end is connected to pull handle.
Can also on outer jointing jacket, be with the O-ring seal that can slide up and down in the said structure of the present utility model, and the front end of outer jointing jacket be provided with protect protruding.The taper of internal protective cover front end, cone angle are 30 °, and are threaded with internal protective cover.Pull bar and outer jointing jacket welding, handle and internal protective cover welding.O-ring seal is made with stainless steel or rigid plastic, and spring hitch is a spring that is converted into convex.
When using this probe; earlier oversheath is depressed; allow spring hitch be stuck in the lower limit hole; the outer jointing jacket lower end is connected with conehead; after sealing internal protective cover, will pop one's head in to insert in the soil reaches prescribed depth, with pull handle oversheath is upwards drawn; till blocking the upper limit hole to spring hitch, soft air enters internal protective cover from air hole.O-ring seal is pressed onto soil surface, and compresses, to prevent the inner air and outer air exchange.After measurement finishes, outer jointing jacket is restored (to pressing to till the lower limit hole blocks spring hitch), extract probe then.Use this structure, guaranteed that earth can not stop up air hole, can not pollute humidity-sensitive element; What simultaneously, assurance was measured is the humidity or the temperature of the soil moisture or humidity rather than atmosphere; Also have, the probe front end is tapered, and is slotting very convenient down in the earth.
Fig. 1 is used for soil moisture or thermometric sonde configuration sketch;
Fig. 2 is the cutaway view Amplified image in Figure 1A place spring hitch and lower limit hole.
Below in conjunction with embodiment the utility model is done a detailed description.
Embodiment 1
A kind of humidity of soil, thermometric probe of being used for comprises humidity-sensitive element 14, change-over circuit 15, internal protective cover 2, outer jointing jacket 3, and humidity-sensitive element 14 and change-over circuit 15 place in the internal protective cover 2.Used humidity-sensitive element 14 and change-over circuit 15 are to use the commercially available prod, and product type is BTHS-EA.Internal protective cover 2 front ends have air hole 10, and soft air advances internal protective cover 2 by air hole 10 and contacts with humidity-sensitive element 14.The front end of internal protective cover 2 is taper, and cone angle is 30 degree, is threaded handle 7 and internal protective cover 2 welding with internal protective cover.Upper limit hole 12 and lower limit hole 11 are arranged on the oversheath 3, match with spring hitch on the internal protective cover 2 respectively, with determine to press down and on the limit of two positions of drawing.Spring hitch is a spring that is converted into " protruding " shape.Pull handle bar 5 and oversheath 3 welding.Except that humidity-sensitive element, all structures are that stainless steel material processes.
Embodiment 2
A kind of soil moisture, thermometric probe of being used for; the annexation of its humidity-sensitive element 14, change-over circuit 15, internal protective cover 2, outer jointing jacket 3 is with implementing 1; its difference is: being with one on outer jointing jacket 3 can be along its O-ring seal that is free to slide 4, is provided with a pair ofly to protect protruding 9 below lower limit hole 11.The effect of O-ring seal is when probe inserts soil, may leave the space between soil and outer jointing jacket 3, like this, behind extraneous air and the soil moisture relative current, measures and can not get actual value.After adding O-ring seal, can be after inserting under the probe, O-ring seal pushed compress, prevent that extraneous air from entering in the soil.Protect protruding effect and be and prevent that O-ring seal from sliding and lose.O-ring seal can process with stainless steel or rigid plastic.
