Reference is made to fig. 1,2 and 3.
When the inertial rotating device is used, the inertial rotating blocks I12 and II 13 rotate rapidly, inertia is overlapped in the vertical direction, and the whole protective housing I7 can vertically lift. The lifting rod 3 on the first protective shell 7 can carry the lifting ring 5 to move upwards after overcoming the field of the tension spring 6.
The communicating pipe 18, the collecting cover 19 and the discharging cover 20 are synchronously lifted and lowered in a reciprocating manner through the transmission of the connecting plate 17.
Through setting up of division board one 21, connecting pipe 22 and division board two 23, can divide into four independent spaces with the pipeline that communicating pipe 18, collection cover 19 and discharge cover 20 constitute, and then can independently deposit cement raw materials, stone, water and sand.

Reference is made to fig. 1,2 and 3.
When the round table-shaped sealing plug 26 is attached to the inner wall of the discharge cover 20, the bottom of a pipeline formed by the communicating pipe 18, the collecting cover 19 and the discharge cover 20 is sealed, the round table-shaped sealing plug 26 is supported at a fixed height through a supporting rod 27 fixedly supported by the external frame, the discharge cover 20 is lifted along with the transmission of the connecting plate 17, in the lifting process, the discharge cover 20 and the round table-shaped sealing plug 26 are continuously contacted and separated, and when the two are separated, stones, cement, water and sand stored in the communicating pipe 18, the collecting cover 19 and the discharge cover 20 can quickly fall down to the storage box 15, and raw materials are guided into the mixing silo 1 through the delivery pipe 16.
And because the mixture in the mixing bunker 1 is less in the initial stage, the rotation resistance to the stirring teeth 14 is also less, under the condition that the output power of an external power source is inconvenient, the rotation speeds of the inertia rotating block I12 and the inertia rotating block II 13 in the initial stage are faster, the inertia of the protection shell I7 is larger, the lifting height of the discharging cover 20 is larger, the gap for the material to flow out between the discharging cover 20 and the round table-shaped sealing plug 26 is also enlarged, and the material can be quickly supplemented in the mixing bunker 1 in the initial stage.
In the subsequent production process, on the contrary, the mixture needs to be mixed and stirred in the mixing bin 1 within a period of time, so that the mixture in the mixing bin 1 is increased, the rotation speeds of the first inertia rotating block 12 and the second inertia rotating block 13 are reduced, and finally, the gap for feeding and discharging between the discharging cover 20 and the circular truncated cone-shaped sealing plug 26 is reduced, the discharging amount is reduced, and the effect of adding raw materials in the mixing bin 1 is achieved.

The second feeding device comprises a disc 28 fixed on the top of the third shaft 24, a limiting sliding groove 29 is formed in the upper surface of the disc 28 and is in limiting sliding connection with a sliding arm 30 through the limiting sliding groove 29, one end, far away from the disc 28, of the sliding arm 30 is fixedly connected with an inertial sliding block 31, the upper surface of the sliding arm 30 is rotationally connected with a rotating arm 32 through a pin shaft, the top of the rotating arm 32 is rotationally connected with a rotating ring 33 through a pin shaft, the top fixed shaft of the rotating ring 33 is rotationally connected with a lifting sleeve 34, the inner wall of the lifting sleeve 34 is in limiting sliding connection with a storage barrel 35 fixedly supported by an external frame, the arc-shaped outline of the storage barrel 35 is provided with four discharge holes for feeding and discharging, and the inner wall of the storage barrel 35 is fixedly connected with a partition plate III 36.
Reference is made to fig. 3, 4 and 5.
Through the above process, the lifting of the communicating pipe 18 drives the synchronous lifting of the partition plate 21 and the connecting pipe 22 in the communicating pipe, the sliding block 25 on the inner wall of the connecting pipe 22 also can synchronously lift, and the sliding block 25 can continuously slide with the inner wall of the outer spiral groove on the outer contour of the shaft three 24 in the lifting process, and under the guidance of the outer spiral groove on the shaft three 24, the shaft three 24 can smoothly rotate on the round table-shaped sealing plug 26, and the rotation of the shaft three 24 drives the rotation of the top disc 28.
The rotation speed of the shaft three 24 is directly influenced by inertia of the first protection shell 7, and when the inertia is large, the rotation speed blocks of the shaft three 24 and the disc 28 are smaller.
The sliding arm 30 slides radially in the limiting chute 29, and once the disc 28 rotates rapidly with the sliding arm 30, the inertial sliding block 31 drives the sliding arm 30 to slide radially and centrifugally in the limiting chute 29 under the influence of inertia.
Under the running fit of the rotating arm 32, the lifting sleeve 34 is vertically pulled down on the storage barrel 35 by the rotating ring 33, so that four discharge ports for feeding and discharging materials on the arc-shaped outline of the storage barrel 35 are exposed, the raw materials stored in the storage barrel 35 are discharged, the discharged raw materials can directly fall into a pipeline formed by the communicating pipe 18, the collecting cover 19 and the discharging cover 20, and finally the bottom of the pipeline is sealed by the round table-shaped sealing plug 26.
Next, in order to avoid clogging of a large amount of raw material in the pipe formed by the communicating pipe 18, the collecting hood 19 and the discharging hood 20, raw material is gradually added to the pipe.
Through the fixed shaft rotation of the rotating ring 33 on the lifting sleeve 34, the rotating requirements of the disc 28, the limiting sliding groove 29, the sliding arm 30, the inertia sliding block 31 and the rotating arm 32 can be ensured, the downward movement of the rotating ring 33 and the lifting sleeve 34 can be finally realized, in the actual use process, a pressure spring can be added in the limiting sliding groove 29, the pressure spring is not shown in the drawing, and the pressure spring can push the discharge cover 20 to make centripetal movement in the limiting sliding groove 29 when inertia is small, so that the lifting sleeve 34 resets on the storage vat 35.
Further, a material stirring rod 37 is fixedly connected to the surface, close to the bottom, of the shaft three 24, and the material stirring rod 37 is made of stainless steel.
Referring to fig. 5, by providing the deflector rod 37, the deflector rod can be rotated together with the shaft three 24, and thus, it is possible to ensure that the raw materials falling from the discharge cap 20 can be preliminarily premixed, and the deflector rod 37 stainless steel can improve durability of the apparatus in use.
Further, be equipped with protective housing two 38 in the blending bunker 1, protective housing one 7, axle one 8, gear one 9, gear two 10, axle two 11, inertial rotation piece one 12 and inertial rotation piece two 13 all are in protective housing two 38, through the setting of protective housing two 38, can separate protective housing one 7, axle one 8, gear one 9, gear two 10, axle two 11, inertial rotation piece one 12 and inertial rotation piece two 13 isotructures and the concrete in the blending bunker 1, avoid receiving the pollution, increase of service life.
Embodiment two:
Substantially the same as in example one, further steps are: the end of the slide block 25 far away from the connecting pipe 22 is an arc surface, and the connecting pipe 22 is in sliding connection with the inner wall of the spiral groove outside the shaft three 24 through the arc surface.
Through the arrangement of the arc surface on the sliding block 25, the sliding of the sliding block 25 in the inner wall of the outer spiral groove on the shaft three 24 can be smoother, and the stability in use is improved. The first inertial rotating block 12, the second inertial rotating block 13 and the inertial sliding block 31 are made of high-density metal, and generate higher inertia during movement.
Working principle: when the concrete preparation system is used, the mixture is subjected to centralized and uniform mixing treatment in the mixing bin 1, so that concrete is finally produced;
the fixed ring 4 is supported by the support frame 2, and the lifting rod 3 can be assisted to realize reciprocating lifting through the arrangement of the fixed ring 4, the lifting ring 5 and the tension springs 6.
The first shaft 8 is driven by a power mechanism to continuously rotate, and the first inertial rotating block 12 and the first gear 9 on the first shaft 8 synchronously rotate;
a second gear 10 meshed with the first gear 9 drives the second shaft 11 and the first inertial rotating block 12 on the second shaft 11 to rotate continuously,
The inertia rotating block I12 generates huge inertia in the rotating process, and as the gear I9 and the gear II 10 are meshed with each other, the rotating angles of the two inertia rotating blocks I12 are opposite, the inertia generated in the horizontal direction can be mutually offset,
Similarly, the inertias of the two inertial rotating blocks II 13 in the horizontal direction can offset each other, and the inertias of the two inertial rotating blocks in the vertical direction can be overlapped with each other. The first shaft 8 and the second shaft 11 drive the two stirring teeth 14 to continuously rotate, so that the raw materials in the mixing bin 1 are fully mixed and stirred, and the mixture can be stirred upwards by adjusting the rotation directions of the two stirring teeth 14, so that stones in the mixture can not sink rapidly.
Under the condition that only inertia generated in the vertical direction is reserved and the power of an external power source on the first shaft 8 is unchanged, the rotation speed of the stirring teeth 14 is affected to be gradually slowed down, so that the inertia on the second inertia rotating block 13 and the first inertia rotating block 12 is synchronously reduced;
the raw materials in the mixing bin 1 can be adaptively supplemented through the arrangement of the first material supplementing device;
Reference is made to fig. 1,2 and 3.
When the inertial rotating device is used, the inertial rotating blocks I12 and II 13 rotate rapidly, inertia is overlapped in the vertical direction, and the whole protective housing I7 can vertically lift. The lifting rod 3 on the first protective shell 7 can carry the lifting ring 5 to move upwards after overcoming the field of the tension spring 6.
The communicating pipe 18, the collecting cover 19 and the discharging cover 20 are synchronously lifted and lowered in a reciprocating manner through the transmission of the connecting plate 17.
By the arrangement of the first partition plate 21, the connecting pipe 22 and the second partition plate 23, the pipeline formed by the communicating pipe 18, the collecting hood 19 and the discharging hood 20 can be divided into four independent spaces, and then cement raw materials, stones, water and sand can be independently stored, with reference to fig. 1, 2 and 3.
When the round table-shaped sealing plug 26 is attached to the inner wall of the discharge cover 20, the bottom of a pipeline formed by the communicating pipe 18, the collecting cover 19 and the discharge cover 20 is sealed, the round table-shaped sealing plug 26 is supported at a fixed height through a supporting rod 27 fixedly supported by the external frame, the discharge cover 20 is lifted along with the transmission of the connecting plate 17, in the lifting process, the discharge cover 20 and the round table-shaped sealing plug 26 are continuously contacted and separated, and when the two are separated, stones, cement, water and sand stored in the communicating pipe 18, the collecting cover 19 and the discharge cover 20 can quickly fall down to the storage box 15, and raw materials are guided into the mixing silo 1 through the delivery pipe 16.
And because the mixture in the mixing bunker 1 is less in the initial stage, the rotation resistance to the stirring teeth 14 is also less, under the condition that the output power of an external power source is inconvenient, the rotation speeds of the inertia rotating block I12 and the inertia rotating block II 13 in the initial stage are faster, the inertia of the protection shell I7 is larger, the lifting height of the discharging cover 20 is larger, the gap for the material to flow out between the discharging cover 20 and the round table-shaped sealing plug 26 is also enlarged, and the material can be quickly supplemented in the mixing bunker 1 in the initial stage.
In the subsequent production process, on the contrary, the mixture needs to be mixed and stirred in the mixing bin 1 within a period of time, so that the mixture in the mixing bin 1 is increased, the rotation speeds of the first inertia rotating block 12 and the second inertia rotating block 13 are reduced, and finally, the gap for feeding and discharging between the discharging cover 20 and the circular truncated cone-shaped sealing plug 26 is reduced, the discharging amount is reduced, and the effect of adding raw materials in the mixing bin 1 is achieved.
Through the setting of feed supplement device two, can carry out the adaptation to the material of clinical storage in the case 15 and supply, avoid appearing the jam of material in the case 15 to guarantee the efficiency of continuous production, refer to fig. 3, fig. 4 and fig. 5.
Through the above process, the lifting of the communicating pipe 18 drives the synchronous lifting of the partition plate 21 and the connecting pipe 22 in the communicating pipe, the sliding block 25 on the inner wall of the connecting pipe 22 also can synchronously lift, and the sliding block 25 can continuously slide with the inner wall of the outer spiral groove on the outer contour of the shaft three 24 in the lifting process, and under the guidance of the outer spiral groove on the shaft three 24, the shaft three 24 can smoothly rotate on the round table-shaped sealing plug 26, and the rotation of the shaft three 24 drives the rotation of the top disc 28.
The rotation speed of the shaft three 24 is directly influenced by inertia of the first protection shell 7, and when the inertia is large, the rotation speed blocks of the shaft three 24 and the disc 28 are smaller.
The sliding arm 30 slides radially in the limiting chute 29, and once the disc 28 rotates rapidly with the sliding arm 30, the inertial sliding block 31 drives the sliding arm 30 to slide radially and centrifugally in the limiting chute 29 under the influence of inertia.
Under the running fit of the rotating arm 32, the lifting sleeve 34 is vertically pulled down on the storage barrel 35 by the rotating ring 33, so that four discharge ports for feeding and discharging materials on the arc-shaped outline of the storage barrel 35 are exposed, the raw materials stored in the storage barrel 35 are discharged, the discharged raw materials can directly fall into a pipeline formed by the communicating pipe 18, the collecting cover 19 and the discharging cover 20, and finally the bottom of the pipeline is sealed by the round table-shaped sealing plug 26.
Next, in order to avoid clogging of a large amount of raw material in the pipe formed by the communicating pipe 18, the collecting hood 19 and the discharging hood 20, raw material is gradually added to the pipe.
Through the fixed shaft rotation of the rotating ring 33 on the lifting sleeve 34, the rotating requirements of the disc 28, the limiting sliding groove 29, the sliding arm 30, the inertial sliding block 31 and the rotating arm 32 can be guaranteed, the downward movement of the rotating ring 33 and the lifting sleeve 34 can be finally realized, in the actual use process, a pressure spring can be added in the limiting sliding groove 29, and when the inertia is small, the pressure spring can push the discharging cover 20 to perform centripetal motion in the limiting sliding groove 29, so that the lifting sleeve 34 resets on the storage barrel 35.
Through the cooperation between the above-mentioned structure and use, solved in the in-service use, because in traditional concrete preparation system, cement, grit and water are quantitative input, the stone that produces in the material input can concentrate the subsidence in even mixing for the concrete quality of producing is difficult to guarantee, brings inconvenient problem for the use.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
