Detailed description of the invention
We are elaborated to thickness sand mixing device of the present utility model with specific embodiment by reference to the accompanying drawings below, understand its structure and composition mode, but can not limit protection domain of the present utility model with this in the hope of more cheer and bright.
Please see Figure 1 and Fig. 2, as seen from the figure, the thickness sand mixing device of Sand for Concrete of the present utility model structurally mainly includes coarse sand bucket 1, special fine sand bucket 7, blender 5 and four belt conveyors.Wherein, four articles of belt conveyors are respectively the first belt conveyor 2, the second belt conveyor 4, the 3rd belt conveyor 6 and the 4th belt conveyor 8.Because most sand all transports by sand carrier in river course, and the stacking place of finished product sand is also not far apart from river course, so whole device is placed on side, river course conventionally.
Under normal circumstances, coarse fodder bucket 1 is located at the position by river bank, and described fines bucket 7 is located near fine sand heap position.Because fed distance is longer, between coarse sand bucket 1 and mixer 5, adopt the mode of two belt conveyor relays to carry out sand conveying.The outlet at bottom position of design medium coarse sand bucket 1 is connected to the low side of the first belt conveyor 2, and the height of the first belt conveyor 2 is terminated at the low side of the second belt conveyor 4, and the height of this second belt conveyor 4 is terminated at the entry position of mixer 5.Above-mentioned the second belt conveyor 4 low sides are positioned at the high-end lower position of the first belt conveyor 2, and the blanking device 3 of a tubular is installed between high-end and the second belt conveyor 4 low sides at the first belt conveyor 2.Can increase security and the stationarity of conveying by blanking device 3, avoid occurring the sand problem of drifting of blowing off.
In like manner, the outlet at bottom position of special fine sand bucket 7 is connected to the low side of the 3rd belt conveyor 6, and the height of the 3rd belt conveyor 6 is terminated at the entry position of mixer 5.For the ease of making and easy to use, above-mentioned coarse fodder bucket 1 and fines bucket 7 are square bucket, the upper inversed taper platform structure of profile, and also the external diameter of coarse fodder bucket 1 is greater than the external diameter of fines bucket 7.
After mixer, coarse sand and special fine sand proportionally evenly mix, and form the rule request that meets Sand for Concrete.The low side of above-mentioned the 4th belt conveyor 8 is located at the outlet at bottom position of described mixer 5, and object is to receive the mixed sand of having mixed, the high-end top of being located at finished sand cabin of the 4th belt conveyor 8.
In the thickness sand mixing device of the utility model Sand for Concrete, as important hydrid component, on described mixer, include support 57, motor 53, sand mixing thick tube 51, mulling sieve 52, receiving hopper 55 and finished product funnel 54.Wherein, sand mixing thick tube 51 and mulling sieve 52 are connected to become a pyramidal structure, and the position that 52 diameter maximums are sieved with mulling in the position of sand mixing thick tube 51 diameter minimums is connected,
This pyramidal structure is fixed on support obliquely, and one end that pyramidal structure is lower connects described motor 53 to receive rotary power, and the higher one end of pyramidal structure connects described receiving hopper 55 to receive coarse sand and special fine sand.
Sidewall middle part at sand mixing thick tube 51 is provided with a support ring 56, and this support ring 56 contacts to realize support with two rollers on support 57, and does not affect the rotation of sand mixing thick tube 51.
Be arranged at the bottom of mulling sieve 52 for receiving the finished product funnel 54 of finished sand, the 4th belt conveyors 8 in the bottom of finished product funnel 54, mixed sand finished product directly transports away by the 4th belt conveyor 8, the high-end top in finished sand cabin of the 4th belt conveyor 8, finished sand is directly transported in finished sand cabin and is stored by the 4th belt conveyor 8.
Above-mentioned sand mixing thick tube 51 and mulling sieve 52 pyramidal structures that are formed by connecting are by being in tilted layout on support 57, make the position of sand mixing thick tube 51 higher than the position of mulling sieve 52, thereby sand can move from high to lower in the time that the two rotates, make from receiving hopper 55 special fine sand and coarse sand out, move to the position of mulling sieve 52 gradually, owing to being all hole on mulling sieve 52, the sand having mixed can drop to finished product funnel 54 from hole.
Certainly, the thickness sand mixing device of Sand for Concrete of the present utility model, except structure composition and working method that above-described embodiment proposes, also comprises other similar structure composition designs and parts replacement.Generally speaking, protection domain of the present utility model also comprises the variation that other it will be apparent to those skilled in the art that and substitutes.
