Description

Add the sand system

Technical field

The utility model relates to a kind of sand system that adds, and relates in particular to a kind of sand system that adds automatically.

Background technology

At present, in construction trade, when producing mortar, generally adopt dual mode to add sand grains, a kind of is to utilize spade etc. instrument is artificial to add, and a kind of in addition is to utilize the auger conveyer to add.

Yet, adopt artificial the interpolation, not enough below existing: (1), time-consuming, effort; (2), the accuracy of measuring of sand grains interpolation is not high; (3), height needs large area space to stack sand grains; (4) dust is big, thereby influences the health of human body.

And utilize the auger conveyer to add sand grains; Because said auger conveyer utilizes its helicallobe to rotate to realize sand grains to transmit, produce friction with sand grains during the helicallobe rotation, thereby cause helicallobe to wear and tear easily; And when sand grains is excessive; The helicallobe of said auger conveyer is damaged easily, so the size of sand grains is restricted.

The utility model content

The utility model purpose be to provide a kind of service life long, can adapt to the sand grains of different sizes and help enhancing productivity add the sand system.

The utility model provides a kind of sand system that adds, and it comprises: control setup, sand jar, Pneumatic butterfly valve and belt feeder;

Said sand jar has sand inlet and sand export;

Said Pneumatic butterfly valve is installed on the sand export of said sand jar, and said Pneumatic butterfly valve is connected with control setup;

Said belt feeder is connected with said control setup, and the sand export of said belt feeder and said sand jar is relative.

Compared with prior art, the beneficial effect of the utility model is:

(1), the utility model adopts belt feeder to carry out the transmission of sand grains, the said relatively belt feeder of sand grains is static, can not cause wearing and tearing or damages belt feeder, makes the said sand system that adds have long service life;

(2), the utility model adds the sand grains that the sand system can be used for carrying various different sizes, range of use is extensive;

(3), the utility model adopts belt feeder to carry sand grains, delivery speed is fast, thereby effectively enhances productivity;

(4), the utility model adopts sand jar storage sand grains, can reduce and stack the required floor area of sand grains;

(5), the utility model adds the sand system and carries out in the sand grains course of conveying, the dust of generation is less, can not influence the health of human body.

Description of drawings

Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:

Fig. 1 adds the structural representation of sand system for the utility model.

The specific embodiment

To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.

Please with reference to Fig. 1, the utility model provides a kind of sand system that adds, and it comprises: sand jar 1, gig 2, Pneumatic butterfly valve 3, belt feeder 4, weighing balance 5, control setup (not shown) and frequency converter (not shown).

The top of said sand jar 1 is provided with sand inlet 11, and its bottom is provided with sand export 12.Said Pneumatic butterfly valve 3 is installed on the sand export 12 of said sand jar 1, and said Pneumatic butterfly valve 3 is connected with control setup (not shown).

Said gig 2 is installed on the side of said sand jar 1, is used for sand grains is transported in the said sand jar 1, and said gig 2 has and is used to the actuating device 23 that loads the loading attachment 21 of sand grains and be used to drive said loading attachment 21 up-and-down movements.When needs deposit sand grains, only need sand grains is poured in the said loading attachment 21, then, start said actuating device 23, utilize said actuating device 23 to drive said loading attachment 21, sand grains is transported to the sand inlet 11 of said sand jar 1 and pours sand jar 1 interior getting final product into.

Said belt feeder 4 electrically connects with said control setup and frequency converter; Said belt feeder 4 have motor (not shown) and with said motor bonded assembly belt conveyor 41; Said motor is under the control of said frequency converter; Can different rotating speed rotate, said belt conveyor 41 is relative with the sand export 12 of said sand jar 1, thereby makes the sand grains that sand export 12 flows out can directly fall on the said belt conveyor 41.Said weighing balance 5 is adjacent with said belt feeder 4, and it is used to measure the weight of sand grains.

When a collection of mortar of production need add sand grains, only need were controlled the electric motor starting of said belt feeder 4 through said control setup and are controlled said Pneumatic butterfly valve 3 and open.After said pneumatic butterfly 3 was opened, sand grains flowed out from the sand export 12 of sand jar 1 automatically, flows on the belt conveyor 41 of said belt feeder 4, is transported to weighing in the said weighing balance 5 through belt conveyor, entered into stirring pool after the weighing and stirred the formation mortar.

Compared with prior art, the beneficial effect of the utility model is:

(6), the utility model is owing to be provided with frequency converter; The motor speed of the said belt feeder of said frequency converter scalable; Thereby make said belt conveyor to rotate, when the interpolation sand grains draws to an end, can reduce said belt feeder motor speed through frequency converter with different speed; Make the delivery speed of belt conveyor of said belt feeder slow down, the weight that makes sand grains add is more accurate.

More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and field of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
