A kind of soil analysis sample screening – grinds the movable integrated machine
Technical field
The present invention relates to the screening of soil analysis sample
–grind the movable integrated machine.
Background technology
The grinding of pedotheque, pulverizing are to carry out soil nutrient in laboratory and the basic link of the index of correlation analysis that becomes to grade.Different nutrient is measured and constituent analysis is different to the requirement of pedotheque particle diameter, and the most frequently used have 0.15mm and two kinds of particle diameters of 2mm.This just needs different milling apparatus and screen cloth.
At present, the grinding of pedotheque and pulverizing mainly contain underhand polish and machine is pulverized two kinds, and quality is respectively arranged.
The device of underhand polish mainly contains two kinds, the mill soil dish that medicine grinds the mortar of formula and push-press type, and its advantage is can be according to the particle diameter of experiment demand manual control pedotheque, and can manually reject impurity such as the root system of plant in sample, solid refuse, stones.Underhand polish is simple to operate, with low cost, pollution-free to sample, and the experimental results degree of accuracy is high, comparatively tallies with the actual situation, the laboratory treatment that suitable sample size is less.But underhand polish efficiency is low, and the amount of labour used is large, takes time and effort, the more more difficult realization of laboratory treatment for sample size.
At present, can be less for the machine soil crushing device in laboratory, existing apparatus mainly is divided into pulverizes two kinds of hammer and Disintegrating knifes, and its advantage is that speed is fast, is applicable to large batch of pedotheque processing.But the device that machine is pulverized mostly is metal material, grind and crushing process in, have unavoidably the part loss and go forward side by side in the soil sample, cause sample easily by heavy metal and trace element pollution, affect the accuracy of experimental data.Existing machine reducing mechanism crush efficiency is low, carry out repeating for 3-4 time operation and just can reach the required particle diameter requirement of experiment, and hack is of poor quality.Simultaneously, machine soil crushing device (especially blade type) can be pulverized the impurity such as root system of plant in sample together in the hack process, and this can have a strong impact on last measurement result.In addition, design is complicated mostly for existing hack machinery, and bulky, noise is large, is difficult for mobilely, and price is high, is not suitable for the indoor soil sample preparation such as laboratory used.
The screening of the soil analysis sample efficient pollution-free therefore, used for laboratory
–ginding process is urgently studied.
Summary of the invention
The objective of the invention is to overcome the problems referred to above and shortcoming, a kind of soil analysis sample screening of using for laboratory is provided
–grind the movable integrated machine.Utilize movable integrated machine of the present invention can overcome Traditional Man grinding labour intensity large, efficiency is low, and cost is high, and the soil analysis sample is pulverized the problems such as inhomogeneous, has advantages of that crush efficiency is high, easy and simple to handle, cheap, experimental reliability is strong.
For realizing that the concrete technical scheme that the object of the invention adopts is:
A kind ofly for laboratory soil analysis sample, screen
–grind the movable integrated machine, by body, charging disposal system, grinding system and sizing screening system, formed, wherein body consists of cuboidal casing, the charging disposal system is arranged at wall box top, the sizing screening system is positioned at the middle and lower part of casing, and grinding system is positioned at middle and upper part placed in the middle setting of casing.
Described casing, its top is provided with a pair of case lid of upwards splitting, and bottom half is equipped with universal wheel, and the casing lateral surface is equipped with the passing handle;
Described charging disposal system, consist of feeder hopper and net screen type baffle plate, after the soil of collection is poured feeder hopper into, after the net screen type baffle plate, the large granular impurities such as leaf, root system of plant is blocked on feeder hopper, and soil enters in casing.
Described grinding system is positioned at the casing middle and upper part, the placed in the middle setting, by servomotor, shaft joint, grinding head, grinding alms bowl body and fixedly crosspiece form, servomotor is connected with grinding head by shaft joint and can drives the grinding head rotation; Shaft joint is changeable type, realizes regulating the distance of grinding head and abrasive surface by the shaft joint of changing different length; Fixedly crosspiece is each up and down, and two ends are fixed on the sidewall of casing, and midpoint is provided with a hole, and the fixedly hole of crosspiece is passed up and down respectively in servomotor, grinding head rotating shaft, rises and supports and fixation; Grinding head is top-shaped vertebral body, is entrenched in and grinds in the alms bowl body and leave intermittently; Abrasive surface and the grinding head profile of grinding the alms bowl body match, bowl-shape like spill, and the bottom of grinding the alms bowl body is provided with aperture, forms similar funnel-form, and through bottom, set aperture flows into the sizing screening system to the soil after grinding.
Described sizing screening system is positioned at the casing middle and lower part, screen cloth, disposable box, consists of, and screen cloth is pulling type, and the particle size range that can require according to experimental analysis is changed arbitrarily the screen cloth of different meshes; Disposable box be positioned at screen cloth under, be drawer-like, can freely extract out or insert, the soil particle after grinding falls into wherein by the screen cloth nature that sieves.
Described moving-member is four universal wheels that equidistantly distribute that are fixed in the all-in-one bottom.
beneficial effect of the present invention:
1. the invention provides a kind of pedotheque of the packaged type for laboratory grinds
–screening all-in-one machine, integrate grinding, screen, and solved Traditional Man grinding labour intensity large, the high in cost of production problem, and workload is little, cheap, easy to operate, and a people can complete all operations were.
2. all-in-one of the present invention, high efficiency, crush efficiency reaches 1800kg/h; The hack quality is good, grinds the abrasive surface and the desired spacing of grinding head of alms bowl body by changing the shaft joint adjustment, and grogs that can disposable hack≤2mm accounts for more than 85%, and the grogs of hack≤0.15mm accounts for more than 65%, screens qualification rate 100%; Safe and reliable, the work continuity is strong.
3. all-in-one of the present invention, grind gained pedotheque experimental result accuracy high, tallies with the actual situation, and greatly improved the validity of determination data.
4. all-in-one of the present invention, manufacture simple, material is easy to get, cheap, volume is little, noise is little, easy to operate, can move freely, be applicable to very much the indoor environment such as laboratory and use, be suitable for extensive popularization; Having solved the extensive pedotheque in laboratory and ground problem, is the inheritance and innovation to forefathers' method.
5. all-in-one of the present invention, upper cover, grinding head, screen cloth, shaft joint, sample collection box etc. all can freely be dismantled, and are convenient to maintenance, replacing and the cleaning of device.
In sum, the present invention is by being designed for the grinding of packaged type pedotheque, the screening all-in-one machine in laboratory, efficiency and quality that the laboratory pedotheque grinds have been guaranteed, there are simple, with low cost, the excellent characteristics of cost performance of manufacture, for the laboratory pedotheque grinds, screening provides useful method to use for reference.
