Abstract
The utility model relates to a buoyancy scale which comprises a fluid container having weighing scale display and a weighing float for placing a measured object in the container, wherein the upper end of the container is provided with a cover plate with a central through hole, and the weighing float is put into the container through the through hole. The scale uses the light float which uniform upper volume, lower volume and weight to support a weighing tray according to the buoyancy principle, and the weight of the measured object is equal to the weight of liquid discharged by the float sinking and is displayed by the sinking depth of the float. The zero point is calibrated according to the height of injected liquid or the scale. The weighing precision of the buoyancy scale can be improved through adjusting the cross section size of a supporting bar of the float and the friction coefficient of the supporting bar of the float and a contact hole of the fluid container. The buoyancy scale has the advantages of simple structure, low cost, exact weighing and convenient use.
Description
Technical field
The utility model relates to weigher, specifically, relates to a kind of flotation balance.
Background technology
For a long time, the never suitable peasant of China uses is used to match the special solid measurer of agricultural chemicals, and peasant's dispenser is arbitrarily to match by rule of thumb always, and solid pesticide is generally taked to grab with hand, or take advantage of with spoon ladle out, the scoop shovel, or general estimation is measured.Nearly all pairing agricultural chemicals is tolerance accurately all, and the agricultural chemicals that matches so often causes two kinds of consequences, and the one, may this dense medicament dose not enough, there are not effect or effect bad after the dispenser, the people produces resistance rapidly for inducing the disease worm; The 2nd, this rare soup may occurring, to add agricultural chemicals excessive, forms unnecessary waste, or cause residues of pesticides to exceed standard.The measurer problem of precisely measuring agricultural chemicals is not properly settled, even diseases prevention worm technology is very effective, science very, the peasant produces practical application effect and also has a greatly reduced quality, the accurate dispenser real with current developed country differs very remote, producing with the safety nuisance free of making great efforts to advocate, the utmost point does not conform to yet, so the solid pesticide measurer that carrying out accurate dispensary needs is developed and is promoted necessary, imperative.
Can use for reference the measurer of making the weighing solid pesticide at present and have three kinds: promptly measure little title, common small-sized day gentle electronic balance that Chinese herbal medicine is used.Preceding two kinds all is by lever principle, and service precision depends primarily on the triangle point stiffness, and production cost is all very high, and price is also higher, and also inconvenient peasant uses in the field; The accuracy of measurement of electronic balance depends primarily on the sensitivity of electronic sensor, and highly sensitive electronic balance product is also very expensive, more is not easy to the long-term accurately use of peasant.Because China's agricultural is backward relatively, peasant's income is low, and the input of buying the producer goods is extremely low, the measurer product that the objective requirement price is low, fragile, not simple to operate.
The utility model content
The purpose of this utility model provides a kind of flotation balance of weighing solid matter.
Flotation balance described in the utility model, comprise have the liquid container that shows the weighing scale and be arranged in container, hold the weighing buoyancy aid that is claimed thing, the upper end of described container is provided with the cover plate with central through hole, and the weighing buoyancy aid is put into container by this hole.
Also have dividing plate in the described container body, have on the dividing plate with cover plate on the corresponding through hole of center pit.
Described weighing buoyancy aid comprises large face plate and has the weighing pressure pin of pointer, pressure pin inserts in the groove of tray bottom surface, perhaps comprise large face plate, have the weighing pressure pin of pointer and be arranged on the chassis of pressure pin lower end that described pressure pin and chassis are hollow body or/and adopt the proportion light material littler than the proportion of water.
Described container comprises vessel and is installed in vessel weighing rule suitable for reading by screw.
Have slotted hole on the described rule, perhaps be provided with level control valve in the container bottom.
The material of described container is a transparent material, and described weighing scale is arranged on container, perhaps is arranged on the pressure pin of weighing buoyancy aid.Flotation balance described in the utility model has the following advantages and good effect:
Flotation balance described in the utility model supports large face plate according to the fully uniform lightweight buoyancy aid of lower volume and quality in the law of buoyancy utilization or pressure pin+floating chamber, alleged weight of object promptly equals the weight that buoyancy aid sinks to arranging liquid, carry out the weight of weighing article represents with the buoyancy aid submergence depth, calibrate zero point according to injecting liquid or rule height, can improve the weighing precision of this measurer by the friction factor of regulating buoyancy aid or pressure pin transversal section size and buoyancy aid and liquid container contact hole.It is simple in structure, and cost is low, and weighing is accurate, and is easy to use, extremely is fit to the peasant and is used for the weighing solid pesticide.
Description of drawings
Fig. 1 is the structural representation of flotation balance described in the utility model;
Fig. 2 is the structural representation of another embodiment of flotation balance described in the utility model;
Fig. 3 is the synoptic diagram of an embodiment of weighing buoyancy aid illustrated in figures 1 and 2.
Embodiment
Referring to Fig. 1, flotation balance described in the utility model, comprise have the liquid container 1 that shows the weighing scale and be arranged in container, hold the weighing buoyancy aid 3 that is claimed thing, the upper end of described container is provided with the cover plate 2 with central through hole, the weighing buoyancy aid is put into container by this hole.
Also have dividing plate 9 in the body of described container 1, have on the dividing plate with cover plate on the corresponding through hole of center pit, pressure pin 4 passes the hole on cover plate and the cover plate, can better be kept upright, and makes the accuracy of its weighing higher.
Described weighing buoyancy aid 3 comprises large face plate 5 and has the weighing pressure pin 4 of pointer 6, and pressure pin 4 inserts in the groove of pallets 5 bottom surfaces, perhaps comprises large face plate 5, has the weighing pressure pin 4 of pointer 6 and is arranged on the chassis 11 of pressure pin lower end, referring to Fig. 3.Described pressure pin and be hollow body or/and adopt the proportion material littler than employed liquid.General liquid adopts water, so pressure pin uses the light material littler than the proportion of water to get final product.
Described container 1 comprises vessel and is installed in the weighing rule 7 of upper opening of container by screw 8 to have slotted hole on this rule, therefore can upper and lower adjusting rule, so that when adding liquid, make pointer aim at zero-bit on the rule.
Rule 7 also can be fixed, as long as the level control valve (not shown) is set in the container bottom, when water add too much the time, open valve and discharge water, also can make pointer point to zero-bit.
During use, in container, add entry, the pressure pin of weighing buoyancy aid is put into vessel, make pointer just in time point to zero-bit on the rule, can use.
Referring to Fig. 2, another embodiment of flotation balance described in the utility model, described container 1 can adopt transparent material to make, as glass, and transparent plastic etc.When adopting transparent material to make, described weighing scale can be set directly on the vessel, perhaps is arranged on the pressure pin of weighing buoyancy aid.During use, only need that water is added to zero-bit and get final product.
