Detailed Description

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a powder low pressure conveyor is used in concrete shop production, a powder low pressure conveyor is used in concrete shop production includes screw conveyer 1, screw conveyer 1 is current structure, do not do too much redundantly here, (can refer to patent CN 215438326U), screw conveyer 1's bottom fixedly connected with lower casing 3, the top of lower casing 3 is provided with upper housing 2, two fixture blocks 9 of bottom fixedly connected with of upper housing 2, the structure homogeneous phase on two fixture blocks 9 is the same, the bottom of fixture block 9 is "V" font, fixture block 9's rear side is seted up and is equipped with spacing groove 10, two draw-in grooves 8 have been seted up at the top of lower casing 3, the diapire shape of two draw-in grooves 8 is "V" font and identical with fixture block 9.

Lower casing 3's rear side is opened and is equipped with recess 11, recess 11 is linked together with draw-in groove 8, two second slide bars 12 of the inside fixedly connected with of recess 11, the structure on two second slide bars 12 is all the same, slider 14 has been cup jointed in the surface slip of second slide bar 12, two slider 14's relative one side fixedly connected with connecting block 15, connecting block 15's surface is at the inner wall sliding connection of recess 11, connecting block 15's surface is at the inner wall sliding connection of spacing groove 10, connecting block 15 is close to the inside that one side of draw-in groove 8 extends to draw-in groove 8, two second springs 13 of fixedly connected with between connecting block 15 and the recess 11 inner wall.

Under the static state, under the action of the elastic force of the second spring 13, one end of the connecting block 15 close to the latch 9 is located inside the limiting groove 10 and blocks each other, and at this time, the upper housing 2 is installed on the top of the lower housing 3.

Two spouts 4 have been seted up on the surface of upper housing 2, the structure homogeneous phase in two spouts 4, the first slide bar of fixedly connected with 5 in the spout 4, push pedal 7 has been cup jointed in the surface slip of first slide bar 5, the both ends of push pedal 7 are the inclined plane, the first spring of fixedly connected with 6 between the inner wall of push pedal 7 and spout 4, spread groove 16 has been seted up at the top of upper housing 2, spread groove 16's top shape is "V" font equally, sliding connection has movable block 18 in spread groove 16, the shape of movable block 18 is the shrink form, fixedly connected with third spring 17 between the inner wall of movable block 18 and spread groove 16.

Under quiescent condition, under the elastic force effect of first spring 6, the surface of movable block 18 and one side butt that two push pedal 7 are close to each other, two third springs 17 are not atress this moment, when needs are dismantled upper casing 2 and lower casing 3 and then be more convenient for overhaul the screw in screw conveyer 1 and clear up the work, move movable block 18 downwards, movable block 18 moves down and compresses third spring 17, because the shape of movable block 18 is the shrink form, the both ends of push pedal 7 are the inclined plane, and then can be smooth when movable block 18 moves down promote the one end that two push pedal 7 are close to each other, improve the operation smoothness nature of integrated device, be more convenient for improve among the low pressure conveyor screw conveyer 1 when transporting the powder for the concrete shop production.

Two push pedal 7 began relative rotation under promoting this moment, again because the both ends of push pedal 7 are the inclined plane, two push pedal 7 relative pivoted other ends begin two connecting blocks 15 one side of being close to each other of smooth promotion, under two push pedal 7's promotion, two connecting blocks 15 begin to move mutually oppositely, two connecting blocks 15 move mutually oppositely and begin to drive slider 14 and move and begin to compress second spring 13 simultaneously, two connecting blocks 15 move mutually oppositely this moment and break away from two spacing grooves 10 gradually, can be smooth at this moment break away from the dismantlement with last casing 2 from lower casing 3.

Move movable block 18 and then two push pedal 7 of smooth promotion back to back of the body and move downwards, final effectual dismantlement work that makes upper housing 2 accomplish with lower casing 3, further improve the workman to spiral delivery rod's in the screw conveyer 1 maintenance efficiency, the dismantlement of completion upper housing 2 and lower casing 3 that messenger's workman can be quick, and then the input is to spiral delivery rod's maintenance work, final more effective improvement low pressure conveyor is at the transport stability and the security to the powder for the concrete workshop production.

After finishing overhauing the screw conveyor pole, need accomplish installation work with upper casing 2 and lower casing 3 this moment, this moment with two fixture blocks 9 aim at two draw-in grooves 8 and move down upper casing 2, because the bottom of fixture block 9 is "V" font, the diapire shape of two draw-in grooves 8 is "V" font and identical with fixture block 9, and then can be smooth drive two fixture blocks 9 in the upper casing 2 downstream and remove to the inside of two draw-in grooves 8, improve the rate of accuracy that fixture block 9 got into in the draw-in groove 8, the integrated device's of being more convenient for use smoothness nature.

In the fixture block 9 entered into draw-in groove 8, the bottom of fixture block 9 began to extrude one side that connecting block 15 is close to draw-in groove 8, connecting block 15 began to move simultaneously to beginning to compress second spring 13 in recess 11 after receiving the extrusion promotion of fixture block 9 this moment, when fixture block 9 fully move entered into draw-in groove 8, one side that connecting block 15 is close to draw-in groove 8 this moment is located the rear side of spacing groove 10, under the elastic force effect of second spring 13, connecting block 15 began to move and resets the inside that enters into spacing groove 10 gradually, the installation work of casing 2 and lower casing 3 is gone up in the final completion.

Through with two fixture blocks 9 on the upper housing 2 aim at two draw-in grooves 8 after the downward movement upper housing 2, final convenient completion upper housing 2 and the installation work of lower casing 3 have further improved the installation effectiveness of integrated device, and then the screw conveyer 1 of being more convenient for is in quick after the maintenance and is put into operation and is accomplished the low pressure transport work to the powder for the concrete shop production.

The working principle is as follows: under the quiescent condition, under the elastic force effect of first spring 6, the surface of movable block 18 and one side butt that two push pedals 7 are close to each other, two third springs 17 are not atress this moment, when needs are dismantled upper casing 2 and lower casing 3 and then be more convenient for overhaul the screw in screw conveyer 1 and clear up the work, move movable block 18 downwards, movable block 18 moves down and compresses third spring 17, because the shape of movable block 18 is the shrink form, the both ends of push pedal 7 are the inclined plane, and then the one end that two push pedals 7 that can be smooth when movable block 18 moves down are close to each other promotes.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
