A kind of soilAnalyzeMovable integrated machine is ground in sample screening
Technical field
The present invention relates to the screening of soil analysis sample–Grind movable integrated machine.
Background technology
The grinding of pedotheque, pulverizing are to carry out, at laboratory, the basic link that the index of correlation such as soil nutrient and composition is analyzed.Different nutrients measures and component analysis is different to the requirement of pedotheque particle diameter, and the most frequently used has two kinds of particle diameters of 0.15mm and 2mm.This is accomplished by different milling apparatus and screen cloth.
At present, the grinding of pedotheque mainly has underhand polish and machine to pulverize two kinds with pulverizing, and is respectively arranged with quality.
The device of underhand polish mainly has medicine to grind mortar and two kinds of the mill soil dish of push-press type of formula, and its advantage is according to the particle diameter of experiment demand Artificial Control pedotheque, and can manually to reject the impurity such as the root system of plant in sample, solid refuse, stone.Underhand polish is simple to operate, with low cost, pollution-free to sample, and experimental results degree of accuracy is high, more tallies with the actual situation, the laboratory treatment of appropriate sample negligible amounts.But underhand polish efficiency is low, the amount of labour used is big, takes time and effort, and the laboratory treatment more for sample size is relatively difficult to achieve.
At present, the machine soil crushing device that may be used for laboratory is less, and existing apparatus is broadly divided into pulverizing hammer and Disintegrating knife two kinds, and its advantage is that speed is fast, is suitable for large batch of pedotheque and processes.But the device that machine is pulverized mostly is metal material, is grinding and in crushing process, having partition losses unavoidably and enter in pedotheque, causing sample easily to be polluted by heavy metal and trace element, affect the accuracy of experimental data.Existing machine reducing mechanism crush efficiency is low, repeats operation for 3-4 time to be carried out and can be only achieved the required Particle size requirements of experiment, and hack is of poor quality.Meanwhile, machine soil crushing device (especially blade type), the impurity such as the root system of plant in sample can be pulverized together during hack, this can have a strong impact on last measurement result.Additionally, existing hack machinery designs complexity mostly, bulky, noise is big, and not easily shifted, price is high, is not suitable for the indoor pedotheques such as laboratory and processes used.
Therefore, the screening of the soil analysis sample efficient pollution-free used for laboratory–Ginding process is urgently studied.
Summary of the invention
It is an object of the invention to overcome the problems referred to above and shortcoming, it is provided that a kind of soil analysis sample screening used for laboratory–Grind movable integrated machine.Utilizing movable integrated machine of the present invention that Traditional Man can be overcome to grind labor intensity big, efficiency is low, and cost is high, and the problems such as soil analysis sample comminution is uneven have the advantage that crush efficiency is high, easy and simple to handle, cheap, experimental reliability is strong.
The concrete technical scheme used for realizing the object of the invention is:
A kind of for the screening of laboratory soil analysis sample–Grind movable integrated machine, it is made up of body, charging processing system, grinding system and sizing screening system, wherein body is made up of cuboidal casing, charging processing system is arranged at wall box top, sizing screening system is positioned at the middle and lower part of casing, and grinding system is positioned at the middle and upper part of casing and is centrally located.
Described casing, its top is provided with a pair case lid the most split, and box bottom is provided with universal wheel, and casing lateral surface is equipped with passage handle;
Described charging processing system, is made up of feed hopper and net screen type baffle plate, after the soil of collection pours feed hopper into, is blocked on feed hopper by the large granular impurity such as leaves, root system of plant after net screen type baffle plate, and soil then enters in casing.
Described grinding system is positioned at casing middle and upper part, is centrally located, and is made up of servomotor, shaft joint, grinding head, grinding bowl and fixing crosspiece, and servomotor is connected with grinding head by shaft joint and grinding head can be driven to rotate;Shaft joint is changeable type, realizes the distance of regulation grinding head and abradant surface by changing the shaft joint of different length;The most each one of fixing crosspiece, two ends are fixed on the sidewall of casing, and midpoint is provided with a hole, and servomotor, grinding head rotating shaft are each passed through the hole fixing crosspiece up and down, rise and support and fixation;Grinding head is top-shaped vertebral body, is entrenched in grinding bowl and leaves interval;The abradant surface grinding bowl matches with grinding head profile, bowl-shape like spill, and the bottom grinding bowl is provided with aperture, constitutes similar funnel-form, and the soil after grinding flows into sizing screening system through aperture set by bottom.
Described sizing screening system is positioned at casing middle and lower part, is made up of screen cloth, disposable box, and screen cloth is pulling type, can arbitrarily change the screen cloth of different meshes according to the particle size range that experimental analysis requires;Disposable box is positioned at the underface of screen cloth, in drawer-like, can freely extract out or insert, and the soil particle after grinding is sieved by screen cloth and naturally falls in wherein.
Described mobile parts, are affixed to bottom all-in-one four universal wheels equidistantly distributed.
Beneficial effects of the present invention:
1. the present invention provides a kind of packaged type pedotheque for laboratory to grind–Screening all-in-one machine, integrates grinding, screens, and solves Traditional Man and grinds labor intensity greatly, and high in cost of production problem, workload is little, cheap, easy to operate, and a people can complete all operations.
All-in-one the most of the present invention, work efficiency is high, and crush efficiency reaches 1800kg/h;Hack quality is good, adjusts the desired spacing of the abradant surface and the grinding head that grind bowl by changing shaft joint, the grogs of disposable hack≤2mm can account for more than 85%, and the grogs of hack≤0.15mm accounts for more than 65%, screening qualification rate 100%;Safe and reliable, work seriality is strong.
All-in-one the most of the present invention, grinds gained pedotheque experimental result accuracy high, tallies with the actual situation, substantially increase the effectiveness of determination data.
All-in-one the most of the present invention, be simple to manufacture, material is easy to get, cheap, volume is little, noise is little, easy to operate, can move freely, be especially suitable for the indoor environment such as laboratory and use, be suitable to be widely popularized;Solve the extensive pedotheque of laboratory and grind problem, be the inheritance and innovation to forefathers' method.
All-in-one the most of the present invention, upper cover, grinding head, screen cloth, shaft joint, sample collection box etc. all can freely be dismantled, it is simple to the maintenance of device, change and clear up.
In sum, the present invention is by being designed for the packaged type pedotheque grinding of laboratory, screening all-in-one machine, ensure that efficiency and quality that laboratory pedotheque grinds, have be simple to manufacture, with low cost, the excellent feature of cost performance, grind for laboratory pedotheque, screening provides useful method and uses for reference.
