Description

Technical Field

[0001] This utility model belongs to the field of detection technology, specifically relating to a portable field lithology identification device. Background Technology

[0002] Rocks on the Earth's crust can be classified into three main categories based on their origin: igneous rocks, sedimentary rocks, and metamorphic rocks. Each of these categories can be further subdivided into different lithological types based on their occurrence, stratigraphic position, and intrusive relationships. Geological surveys are crucial for formulating national and regional geological work plans, meeting societal needs for mineral prediction, mineral exploration, hydrogeology, engineering geological investigation, geological environmental protection and management, tourism, and natural history awareness, as well as providing vital data for land development, remediation, planning, and comprehensive development and utilization of marine resources. Accurate field lithology determination is fundamental to the quality of data compiled by geologists during geological surveys. Generally, field lithology is determined based on characteristics such as color, structure, texture, mineral composition and crystallization state, grain size, alteration, and mineralization. Since some mineral components and lithologies are difficult to observe and distinguish directly, and conducting laboratory testing and analysis after sampling is time-consuming and labor-intensive, simple field testing using certain reagents is often employed for determination. For example, limestone and dolomite formed in certain special sedimentary environments are difficult to distinguish in terms of color, structure, and tectonic features. In the field, a dilute hydrochloric acid reaction is often performed (CaCO3 + 2HCl = CaCl2 + H2O + CO2↑), and the intensity of bubbling is observed to determine the strata. Furthermore, in the field search for phosphate-bearing rock formations, due to the abundance of associated minerals in phosphate-bearing rock blocks, accurately identifying the stratigraphic position of phosphate-bearing rock formations through observation is difficult. In the field, the pale yellow crystals (PO4) precipitated by the reaction of dilute nitric acid with ammonium molybdate on the rock block to be identified are often observed. 3- +12MoO4 2- +3NH 4+ +24H + =(NH4)3[P(Mo 12 O 40 The condition )]6H2O↓+6H2O) was identified.

[0003] Currently, geologists often use narrow-mouthed reagent bottles and simple plastic bottles to carry acid solutions during field titration tests, with droppers stored separately. In the field, the bumps and shaking from walking frequently cause acid leaks, corroding the body and other personal belongings. Furthermore, most droppers are made of ordinary glass, making them easily damaged by pressure during movement. Therefore, it is necessary to design a portable field lithology identification device that integrates reagent storage and dropper storage, making it easy to carry, preventing leakage and damage, and allowing for quantitative liquid dispensing, facilitating field titration tests. Summary of the Invention

[0004] This invention provides a portable field lithology identification device that integrates reagent storage and a dropper, making it convenient to carry, preventing leakage and damage, and allowing for quantitative liquid dispensing for easy field titration testing. The specific solution is as follows:

[0005] A portable field lithology identification device includes a sleeve and a dropper with a rubber head disposed inside the sleeve. The sleeve has closed ends. The dropper includes a rubber head and a tube body. The sleeve includes a sleeve head, a sleeve middle, and a sleeve tail. The sleeve head and sleeve tail are detachably connected to the sleeve middle. The inner wall of the sleeve middle is provided with multiple sliding rails spaced circumferentially. A card is horizontally disposed inside the sleeve middle. The card has a through hole at its center that allows the lower half of the tube body to pass through. The outer periphery of the card has grooves that correspond one-to-one with the sliding rails. Each sliding rail has a limiting element at both ends that limits the upper and lower limits of the card.

[0006] Furthermore, the sleeve is provided with an inverted conical limiting ring at one end that can press against the connection between the rubber head and the tube body.

[0007] Furthermore, a shock-absorbing rubber ring is attached inside the through hole.

[0008] Furthermore, a splash-proof film is horizontally provided inside the tail, and at least three slits are opened on the surface of the splash-proof film.

[0009] Furthermore, the outer wall of the sleeve is marked with graduations along its length, and the volume between two adjacent graduation lines is 1 ml.

[0010] Furthermore, the sleeve head and sleeve tail are respectively connected to the sleeve center by threads.

[0011] The beneficial effects of this utility model are:

[0012] 1. The present invention provides a limiting ring inside the sleeve and a card and limiting component inside the sleeve to keep the dropper stable. The anti-vibration rubber ring inside the through hole ensures that it will not be damaged during carrying.

[0013] 2. The device of this utility model is provided with a sliding rail, a card and a limiting component in the sleeve. By moving the limiting component, the upper and lower limit positions of the card can be adjusted and fixed, thereby achieving the function of absorbing reagents and fixing the dropper.

[0014] 3. The device of this utility model is equipped with a splash-proof film inside the sleeve tail. When not in operation, the splash-proof film is in a closed state, allowing a small amount of leakage. When the limiting member is in the lower limit position, the dropper can freely enter and exit the sleeve tail through the center of the splash-proof film, thereby absorbing or adding reagents. The sleeve body is provided with graduations along its length, which can facilitate quantitative absorption or addition of reagents.

[0015] 4. The device of this utility model has detachable threaded connections at the head, middle, and tail of the sleeve, which facilitates cleaning and maintenance. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] See Figure 1-3 A portable field lithology identification device includes a sleeve and a dropper with a rubber head disposed inside the sleeve. The sleeve has closed ends. The dropper includes a rubber head 1 and a tube body 2, with a gap between the top of the rubber head 1 and the sleeve. The sleeve includes a sleeve head 3, a sleeve middle 4, and a sleeve tail 5. The sleeve head 3 and the sleeve tail 5 are detachably connected to the sleeve middle 4. The inner wall of the sleeve middle 4 is provided with multiple sliding rails 9 spaced circumferentially and respectively arranged in four directions of the sleeve middle 4. A card 7 is horizontally disposed inside the sleeve middle 4. The center of the card 7 has a through hole for the lower half of the tube body 2 to pass through. The outer periphery of the card 7 has a sliding groove that corresponds to the sliding rails 9 one by one. The sliding rails 9 and the sliding grooves are tightly sealed. Each sliding rail 9 has a limiting element 10 at both ends to limit the upper and lower limits of the card 7. The limiting element 10 is a rubber pad, which is wrapped around the upper and lower ends of the sliding rail 9. The sliding groove is locked onto the rubber pad by manual adjustment to complete the limiting and fixing.

[0022] The preferred sleeve 3 is provided with an inverted conical limiting ring 6 at one end that can press against the connection between the rubber head 1 and the tube body 2. The rubber head dropper can be fixed by the limiting ring 6 pressing against the top of the tube body 2 and combined with the through hole on the card 7, so as to prevent it from shaking and causing damage to the tube body 2.

[0023] The preferred through hole is fitted with a shock-absorbing rubber ring 8, which can prevent the glass tube body 2 from being squeezed and damaged during the limiting process and can ensure its sealing.

[0024] The preferred sleeve tail 5 has a horizontal anti-splash film 11 inside. The surface of the anti-splash film 11 has at least three slits 1101. The anti-splash film 11 can be set in a closed state when not in operation, which can prevent a large amount of reagent leakage.

[0025] The preferred tail 5 has a scale 12 on its outer side wall along its length, and the volume between two adjacent scale lines is 1 ml. The design of scale 12 allows for intuitive observation of the amount of reagent absorbed, thus avoiding waste.

[0026] The preferred sleeve head 3 and sleeve tail 5 are respectively connected to the sleeve middle 4 by threads, wherein the threaded connection is easy to disassemble, so as to facilitate cleaning and maintenance.

[0027] The working principle of this utility model is as follows: First, unscrew the threads of the sleeve head 3 and sleeve 4 and remove the dropper. Then, move the card 7 of sleeve 4 to the lower limit stop 10 to complete the limiting and fixing. Next, hold the dropper downwards so that the head of the tube body 2 extends into the anti-splash film 11 inside the sleeve tail 5 to draw up the reagent, and then remove it for testing and identification. When not in use, move the card 7 of sleeve 4 to the upper limit stop 10 to complete the locking, place the dropper and cover the sleeve head 3, and tighten the threads.

[0028] When replenishing reagent at the end of the sleeve 5, the method of aspirating reagent described above can be used; alternatively, the threads of the sleeve 4 and the end of the sleeve 5 can be unscrewed for replenishment. It is worth noting that when replenishing reagent using the latter method, the end of the sleeve 5 must be kept stable, and care should be taken to avoid corrosion from the remaining reagent in the nozzle 1.

[0029] This utility model integrates reagent storage and a dropper into one unit, which is not only convenient to carry and avoids leakage and damage, but also allows for quantitative liquid dispensing, facilitating field titration testing. The head 3, middle 4, and tail 5 are connected by detachable threaded connections, making cleaning and organization convenient. It has a very high cost performance and is worth promoting.
