Description

Spheroidal sand big gun

Technical field

The utility model belongs to the fireworks technical field, especially relates to the spheroidal sand big gun of a kind of follow-on hand-thrown outburst sound and colored light effect.

Background technology

In the prior art, the sand big gun of traditional hand-thrown outburst sound, generally be to be rolled on the sand so that the mixture of red phosphorus and realgar is sticking, make with tissue paper afterturn parcel again, likeness in form tadpole shape, though this sand big gun handling ease, owing to adopt the manual parcel of afterturn singly to form, processing and fabricating speed is slow, work efficiency is extremely low, and product colour is single, needs during packing to fill a large amount of wood sawdusts in packaging bag, in case the percussion blast, sand and wood chip are sprinkling upon on the ground full when playing, contaminated environment more is not easy to play indoor, and the product moisture-sensitive is damaged, influence quality, poor stability; The applicant has obtained the improvement molding sand big gun that State Patent Office is authorized in first to file; this sand big gun is a kind of tube structure sand big gun; though traditional hand rubbing being twisted with the fingers the structure and the manufacture craft of formula paper sand big gun improves; but in large-scale production, still there are many defectives; especially in the product design and the packing of product, can not satisfy people's needs, suddenly treat further to improve and develop new generation product.

The utility model content

The purpose of this utility model be to overcome above-mentioned the deficiencies in the prior art part and provide that a kind of structure is simpler, processing and fabricating is simpler and easy, be suitable for the mechanization high efficiency production, security is good, it is easy to use to play, have multiple coloured appearance effect and colored light effect, a kind of spheroidal sand big gun of environment-friendly type.

The purpose of this utility model can realize by following technical measures:

A kind of spheroidal sand big gun, comprise white and colour, by kernel and outer the composition, be spherical shape, its special character is: the center of this ball is rigid thing kernel, and skin is mixed sand medicine layer and overcoat, mixed sand medicine layer is along the bonding parcel in inner core particles surface, overcoat is bonding to be wrapped on the top layer face of mixed sand medicine layer, organically forms a whole spherical shape behind granulating and forming, and adhesive is Instant cement or water; Mixed sand medicine layer is the mixture of explosive and auxiliary material, and auxiliary material is sand grains or ore powder, and this auxiliary material plays friction effect and plays mutual effect of impact with kernel with explosive in mixed sand medicine layer.

In such scheme, described overcoat is the moisture protection layer that adds chromatic colour agent and anti-blushing agent; Described kernel be rigid plastics round shaped grain of all kinds or for vulcanie round shaped grain of all kinds for river sand round shaped grain or for the circle beans; The big I of the round shaped grain of its kernel is decided according to the required specification size of spheroidal sand big gun.

The utility model of structure is the innovation improvement to prior art thus, and its advantage and good effect are:

1, adopted and moulded firmly or hard rubber or other adamant round shaped grain are that kernel is wrapped up in drug carrier; remove sand and wrapped up in drug carrier; simple in structure, processing technology thereof is easy, and the granulating and forming size is consistent; be spherical shape; abolish handbag afterturn formula making one by one and in bobbin, spread the manufacture craft of putting the sand medicine and smearing sealing compound, saved a large amount of manpowers and man-hour, the production efficiency height; contrast bobbin sand big gun single rate can improve on the effect ten times, has realized the scale high efficiency production.

2, owing to wrap up in the moisture protection layer that one deck adds chromatic colour agent and anti-blushing agent at the top layer bread of mixed sand medicine layer; overcome the shortcoming of the single and moisture-sensitive of original sand big gun color; be convenient to multi-form moulding packing; its container dimensions is elegant in appearance; the color intuitive is strong; the product humidity resistance is good, and the storage time is long.

3, easy to use, security is good, and hand is firmly pinched the fried hand of medicine ball, but detonates with throwing, and the clear and melodious shake ear of sound has been eliminated when playing completely wood chip, meets the environment-friendly products requirement, is convenient to child and plays indoor, can substitute existing paper bag sand big gun or bobbin sand big gun fully.

Description of drawings

Fig. 1 is the cross-sectional view of the utility model spheroidal sand big gun.

Among Fig. 1,1-kernel, 2-mixed sand medicine layer, 3-overcoat.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 shows embodiment of the present utility model.A kind of spheroidal sand big gun, comprise white and colour, by kernel and outer the composition, be particle ball shape, architectural feature is: the center of this ball is rigid thing kernel 1, skin is mixed sand medicine layer 2 and overcoat 3, closely wrap up bonding granulation with kernel successively by mixed sand medicine layer 2 and overcoat 3 and constitute three layers of white or colored spheroidal sand big gun, adhesive adopts homemade liquid Instant cement (also can be water), mixed sand medicine layer 2 is to use explosive and auxiliary material through pulverizing, the liquid Instant cement of mixing back adding that makes up a prescription stirs into the colloidal liquid mixture as adhesive, auxiliary material is granule river sand or quartz sand dry mash, this auxiliary material in mixed sand medicine layer 2 with explosive rise friction effect and with 1 mutual effect of impact of kernel; Overcoat 3 is the liquefied mixtures that add the chromatic colour agent in anti-blushing agent; Described kernel 1 is selected rigid plastics round shaped grain of all kinds for use, and medicine ball is outer, and to constitute specification with kernel be that different size according to spheroidal sand big gun requires to decide; Kernel 1 also can be selected vulcanie round shaped grain of all kinds or river sand round shaped grain or circle beans for use.

The making of this spheroidal sand big gun is to be packaged into finished product after adopting bright pearl comminutor processing granulating and forming.

During use, take out the inner packing body that colored spheroidal sand big gun is housed in the packing object, take encapsulation apart, hand is pinched colored spheroidal sand big gun, promptly sends the colored light and the sound with throwing.

The utility model is not limited to the foregoing description; it can be the colored spheroidal sand big gun of the band kernel desired structure of any specification; as long as with the adamant is that kernel is made carrier; the bonding on its outer surface big gun that can play the friction effect of impact that is enclosed with rings medicine layer and the moisture protection layer that is added with toner, all belongs to protection domain of the present utility model.

Claims (2)

1, a kind of spheroidal sand big gun, by kernel and outer the composition, be spherical shape, it is characterized in that: the center of this ball is a rigid thing kernel (1), skin is mixed sand medicine layer (2) and overcoat (3), and mixed sand medicine layer (2) is along the bonding parcel of kernel (1) particle surface, and overcoat (3) is bonding to be wrapped on the top layer face of mixed sand medicine layer (2), organically form a whole spherical shape behind bonding granulating and forming, its adhesive is liquid Instant cement or water.

2, spheroidal sand big gun according to claim 1 is characterized in that: described kernel (1) for rigid plastics round shaped grain of all kinds or for vulcanie round shaped grain of all kinds for river sand round shaped grain or for the circle beans.
