The resistance spring is always in a compressed state.
In an initial state, the material pushing plate is positioned on one side of the bearing plate, and the bearing plate limits the material pushing plate to move in a square groove formed in the mounting block; when the bearing plate moves to the lowest side of the square groove formed in the mounting block, the lowest side of the material pushing plate is located on the upper side of the bearing plate.

When the adjusting disc rotates, the adjusting disc can drive the threaded rod connected with the adjusting disc to rotate, and the four adjusting blocks are respectively arranged in the four square mounting grooves formed in the mounting block, so that the four adjusting blocks can slide relative to the corresponding square mounting grooves and cannot rotate; the four adjusting blocks are connected with the corresponding threaded rods in a matched manner through threads; the threaded rod can only rotate and cannot move; a resistance spring is respectively arranged between the four adjusting blocks and the corresponding limiting blocks, so that when the threaded rod rotates, the corresponding adjusting blocks move towards the corresponding limiting blocks; the adjusting block moves to push the corresponding resistance spring, and one ends of the four limiting blocks, which are not provided with inclined planes, are respectively installed in four square installation grooves formed in the installation block through the matching of the guide block and the guide groove; the four limiting blocks cannot slide out of the corresponding square mounting grooves, so that the resistance springs are compressed when the adjusting blocks push the corresponding resistance springs, the compressible amount of the resistance springs is reduced, and the elastic strength of the resistance springs is increased; when the corresponding adjusting block moves away from the corresponding limiting block; the adjusting block moves to pull the corresponding resistance spring, so that the compressible amount of the resistance spring is increased, namely the elastic strength of the resistance spring is reduced; because the resistance spring is always in a compressed state, when the resistance spring is pulled, the resistance spring also has pressure on the limiting block; the stretching of resistance spring can not make the stopper take place to remove, can not influence the limiting displacement of stopper to the bearing plate. The resistance that the stopper provided to the bearing plate is adjusted through the size of the volume that adjusts the resistance spring compressible, adjusts the bearing capacity of bearing plate through the size of the volume that adjusts the resistance spring compressible promptly, and then adapts to the weight of the concrete of the different batching that the rabbling mechanism can stir.
The first guide block arranged on the bearing plate is designed to prevent the material pushing plate from interfering with the limiting block positioned outside the square groove in the moving process; the limiting blocks are matched with the bearing plate to move to the two sides of the square groove, so that the limiting blocks can limit the bearing plate and cannot influence the movement of the material pushing plate.
When the bearing plate moves downwards, the bearing plate drives the guide block arranged on the bearing plate to move downwards; the guide block moves downwards to drive the connecting rod to move downwards; the connecting rod moves downwards to drive the rack to move downwards; the rack moves downwards to enable the second gear meshed with the rack to rotate; the second gear wheel rotates to drive the fixed rotating shaft to rotate; in the invention, the material pushing plate is positioned at one side of the bearing plate in the initial state, and the bearing plate limits the material pushing plate to move in a square groove formed in the mounting block; namely, the material pushing plate is in a static state and cannot move in the state; namely the push rod is in a static state; that is, the first gear is in a stationary state in this state; the inner end of the spiral spring is arranged on the outer circular surface of the fixed rotating shaft, and the outer end of the spiral spring is arranged on the end surface of the first gear; therefore, in this state, the rotation of the fixed rotating shaft will make the inner end of the spiral spring rotate, and the rotation of the inner end of the spiral spring will drive the outer end of the spiral spring to rotate.
When the bearing plate moves to the lowest side of the square groove, the lowest side of the material pushing plate is positioned on the upper side of the bearing plate; at the moment, the bearing plate loses the limiting effect on the material pushing plate, the outer end of the volute spiral spring is released instantly, and the outer end of the volute spiral spring rotates; the outer end of the volute spiral spring rotates to drive the first gear to rotate; the first gear rotates to enable the push rod meshed with the first gear to move; the push rod moves to drive the material pushing plate to move; in the moving process of the material pushing plate, once the material pushing plate moves to the upper side of the bearing plate, the material pushing plate can limit the bearing plate to enable the bearing plate to be in a static state, at the moment, the second gear is in the static state, namely the inner end of the volute spiral spring is in the static state, namely the volute spiral spring can continuously release pressure to enable the material pushing plate to continuously move; that is, the pushing plate is driven by the instant releasing force of the volute spiral spring in the initial moving process, and when the pushing plate moves to the upper side of the bearing plate, the pushing plate is driven by the integral compression force of the volute spiral spring.
When the material pushing plate moves to one side, closest to the stirring mechanism, in the square groove, the push rod is manually pulled to drive the material pushing plate to move; in this state, when the material pushing plate is positioned on the upper side of the bearing plate, the material pushing plate plays a limiting role on the bearing plate so that the bearing plate is in a static state; i.e. the second gear is in a stationary state; in this state, the movement of the push rod causes the first gear to rotate; the first gear rotates to enable the outer end of the spiral spring to rotate, the outer end of the spiral spring rotates to drive the inner end of the spiral spring to rotate, but in the state, the second gear is in a static state, namely the inner end of the spiral spring is in a static state, so that the spiral spring is reversely stressed upwards in the state; when the material pushing plate moves to the original position completely, the inner end of the spiral spring is released instantly, and the inner end of the spiral spring rotates; the inner end of the volute spiral spring rotates to drive the second gear to rotate; the second gear wheel rotates to enable the rack to move upwards; the rack moves upwards to drive the bearing plate to move upwards through the connecting rod.
Compared with the traditional pushing device technology, the pushing device designed by the invention can ensure that the concrete ingredients loaded on the bearing plate through the loading mechanism can be automatically pushed into the stirring mechanism through the matching of the bearing plate and the pushing plate; the resistance of the limiting block to the bearing plate can be adjusted by adjusting the deformable amount of the resistance spring; thereby being suitable for the weight of the concrete with different ingredients which can be stirred by the stirring mechanism.

In summary, the following steps:
the beneficial effects of the design of the invention are as follows: the material pushing device 1 can enable concrete ingredients loaded on the bearing plate 8 through the loading mechanism to be automatically pushed into the stirring mechanism through the matching of the bearing plate 8 and the material pushing plate 6; the resistance of the limiting block 24 to the bearing plate 8 can be adjusted by adjusting the deformable amount of the resistance spring 25 through the limiting block 24 and the resistance spring 25 designed by the invention; thereby being suitable for the weight of the concrete with different ingredients which can be stirred by the stirring mechanism.
In the invention, when the adjusting disc 5 rotates, the adjusting disc 5 can drive the threaded rod 27 connected with the adjusting disc to rotate, and because the four adjusting blocks 26 are respectively arranged in the four square mounting grooves 13 formed in the mounting block 7, the four adjusting blocks 26 can slide relative to the corresponding square mounting grooves 13 and cannot rotate; the four adjusting blocks 26 are in threaded fit connection with corresponding threaded rods 27; the threaded rod 27 can only rotate and cannot move; a resistance spring 25 is respectively arranged between each of the four adjusting blocks 26 and the corresponding limiting block 24, so that when the threaded rod 27 rotates, the corresponding adjusting block 26 moves towards the corresponding limiting block 24; the adjusting block 26 moves to push the corresponding resistance spring 25, and the ends of the four limiting blocks 24 which are not provided with inclined planes are respectively arranged in the four square mounting grooves 13 formed in the mounting block 7 through the matching of the guide blocks and the guide grooves; the four limit blocks 24 cannot slide out of the corresponding square mounting grooves 13, so that when the adjusting blocks 26 push the corresponding resistance springs 25, the resistance springs 25 are compressed, the compressible amount of the resistance springs 25 is reduced, namely the elastic strength of the resistance springs 25 is increased; when the corresponding adjustment block 26 moves away from the corresponding stop block 24; the movement of the adjusting block 26 pulls the corresponding resistance spring 25, so that the compressible amount of the resistance spring 25 becomes larger, that is, the elastic strength of the resistance spring 25 becomes smaller; since the resistance spring 25 is always in a compressed state, when the resistance spring 25 is pulled, the resistance spring 25 also has pressure on the limiting block 24; the stretching of resistance spring 25 will not make stopper 24 move, and will not affect the limiting function of stopper 24 to bearing plate 8. The resistance of the limiting block 24 to the bearing plate 8 is adjusted by adjusting the amount of the compressible resistance spring 25, that is, the bearing amount of the bearing plate 8 is adjusted by adjusting the amount of the compressible resistance spring 25, so as to adapt to the weight of the concrete with different ingredients which can be stirred by the stirring mechanism.
The first guide block 23 arranged on the bearing plate 8 is designed to prevent the material pushing plate 6 from interfering with the limiting block 24 positioned outside the square groove 10 in the moving process; the limiting blocks 24 and the bearing plate 8 are matched and moved to the two sides of the square groove 10, so that the limiting blocks 24 can limit the bearing plate 8 and cannot influence the movement of the material pushing plate 6.
When the bearing plate 8 moves downwards, the bearing plate 8 drives the guide block 44 arranged on the bearing plate to move downwards; the guide block 44 moves downwards to drive the connecting rod 35 to move downwards; the connecting rod 35 moves downwards to drive the rack 22 to move downwards; the downward movement of the rack 22 causes the second gear 20 engaged therewith to rotate; the second gear 20 rotates to drive the fixed rotating shaft 31 to rotate; in the invention, as the material pushing plate 6 is positioned at one side of the bearing plate 8 in the initial state, the bearing plate 8 limits the material pushing plate 6 to move in the square groove 10 formed on the mounting block 7; namely, the material pushing plate 6 is in a static state and cannot move in the state; i.e. the push rod 37 is in a rest state; that is, the first gear 19 is in a stationary state in this state; the inner end of the scroll spring 21 is arranged on the outer circular surface of the fixed rotating shaft 31, and the outer end of the scroll spring 21 is arranged on the end surface of the first gear 19; in this state, therefore, rotation of fixed shaft 31 causes rotation of the inner end of scroll spring 21, and rotation of the inner end of scroll spring 21 causes rotation of the outer end of scroll spring 21, but in this state, first gear 19 is in a stationary state, i.e., the outer end of scroll spring 21 is in a stationary state, so that scroll spring 21 is forced up.
When the bearing plate 8 moves to the lowest side of the square groove 10, the lowest side of the material pushing plate 6 is positioned at the upper side of the bearing plate 8; at the moment, the bearing plate 8 loses the limiting effect on the material pushing plate 6, the outer end of the volute spiral spring 21 is released instantly, and the outer end of the volute spiral spring 21 rotates; the outer end of the scroll spring 21 rotates to drive the first gear 19 to rotate; the rotation of the first gear 19 causes the push rod 37 engaged therewith to move; the push rod 37 moves to drive the material pushing plate 6 to move; in the moving process of the material pushing plate 6, once the material pushing plate 6 moves to the upper side of the bearing plate 8, the material pushing plate 6 limits the bearing plate 8 so that the bearing plate 8 is in a static state, at this time, the second gear 20 is in a static state, that is, the inner end of the volute spiral spring 21 is in a static state, that is, the volute spiral spring 21 can continuously release pressure so that the material pushing plate 6 continuously moves; that is, the material pushing plate 6 is driven by the instant releasing force of the spiral spring 21 during the initial movement, and when the material pushing plate 6 moves to the upper side of the bearing plate 8, the movement of the material pushing plate 6 is driven by the overall compression force of the spiral spring 21.
In the invention, when the material pushing plate 6 moves to one side of the square groove 10 closest to the stirring mechanism, the push rod 37 is manually pulled to drive the material pushing plate 6 to move by the push rod 37; in this state, when the material pushing plate 6 is positioned on the upper side of the bearing plate 8, the material pushing plate 6 limits the bearing plate 8 so that the bearing plate 8 is in a static state; i.e. the second gear 20 is in a stationary state; in this state, the movement of the push rod 37 causes the first gear 19 to rotate; the rotation of the first gear 19 causes the outer end of the spiral spring 21 to rotate, and the rotation of the outer end of the spiral spring 21 drives the inner end of the spiral spring 21 to rotate, but in this state, the second gear 20 is in a stationary state, i.e. the inner end of the spiral spring 21 is in a stationary state, so in this state, the spiral spring 21 is reversely forced upwards; when the material pushing plate 6 is completely moved to the original position, the inner end of the spiral spring 21 is released instantly, and the inner end of the spiral spring 21 rotates; the inner end of the scroll spring 21 rotates to drive the second gear 20 to rotate; the rotation of the second gear 20 causes the rack 22 to move upward; the upward movement of the rack 22 causes the bearing plate 8 to move upward via the connecting rod 35.
The specific implementation mode is as follows: when the automatic material pushing device 1 designed by the invention is used, the resistance of the damping spring is adjusted through the ingredients of concrete and the amount of the material which can be accommodated by the mixer before use; namely, the four adjusting disks 5 are adjusted to rotate, and the adjusting disks 5 drive the threaded rod 27 to rotate; when the threaded rod 27 rotates, the corresponding adjusting block 26 moves towards the corresponding limiting block 24; the adjustment block 26 moves to make the corresponding resistance spring 25 become longer or shorter, i.e. the compressible amount of the resistance spring 25 becomes larger or smaller, i.e. the resistance of the resistance spring 25 changes; after the adjustment is finished, loading materials to the upper side of the bearing plate through a loading mechanism; in the charging process, the gravity on the bearing plate is continuously increased; the pressure of the bearing plate on the four limit blocks 24 is gradually increased; the loading plate compresses the stopper 24 so that the stopper 24 moves toward the inside of the square mounting groove 13; when the four limit blocks 24 are completely moved into the corresponding square mounting grooves 13 by the gravity of the bearing plate added with concrete ingredients, the bearing plate 8 moves downwards under the action of the gravity; when the bearing plate 8 moves downwards, the bearing plate 8 drives the guide block 44 to move downwards; the guide block 44 moves downwards to drive the connecting rod 35 to move downwards; the connecting rod 35 moves downwards to drive the rack 22 to move downwards; the downward movement of the rack 22 causes the second gear 20 to rotate; the second gear 20 rotates to drive the fixed rotating shaft 31 to rotate; rotation of fixed shaft 31 urges spiral spring 21 upward. When the bearing plate 8 moves to the lowest side of the square groove 10, the bearing plate 8 loses the limiting effect on the material pushing plate 6, at the moment, the outer end of the volute spiral spring 21 is released instantly, and the outer end of the volute spiral spring 21 rotates; the outer end of the scroll spring 21 rotates to drive the first gear 19 to rotate; the rotation of the first gear 19 causes the push rod 37 to move; the push rod 37 moves to drive the material pushing plate 6 to move; in the moving process of the material pushing plate 6, once the material pushing plate 6 moves to the upper side of the bearing plate 8, the material pushing plate 6 limits the bearing plate 8 so that the bearing plate 8 is in a static state, at this time, the second gear 20 is in a static state, that is, the inner end of the volute spiral spring 21 is in a static state, that is, the volute spiral spring 21 can continuously release pressure so that the material pushing plate 6 continuously moves; after pushing is finished, the push rod 37 is manually pulled, so that the push rod 37 drives the material pushing plate 6 to move; the movement of the push rod 37 causes the first gear 19 to rotate; the rotation of the first gear 19 causes the outer end of the spiral spring 21 to rotate, and the rotation of the outer end of the spiral spring 21 drives the inner end of the spiral spring 21 to rotate, but in this state, the second gear 20 is in a stationary state, i.e. the inner end of the spiral spring 21 is in a stationary state, so in this state, the spiral spring 21 is reversely forced upwards; when the material pushing plate 6 is completely moved to the original position, the inner end of the spiral spring 21 is released instantly, and the inner end of the spiral spring 21 rotates; the inner end of the scroll spring 21 rotates to drive the second gear 20 to rotate; the rotation of the second gear 20 causes the rack 22 to move upward; the upward movement of the rack 22 causes the bearing plate 8 to move upward via the connecting rod 35.
