TECHNICAL FIELD

[0001] The present application relates to the field of concrete production, in particular to a concrete production system. BACKGROUND

[0002] The concrete production system comprises an aggregate storage device, an aggregate conveying device, a powder storage device, a powder conveying device, a water material storage device, a water material conveying device and a mixing tank for mixing aggregate, powder and water material; wherein the aggregate is usually a stone block with a certain diameter or other particle size larger raw material.

[0003] The aggregate storage device comprises a storage tank and a discharging chute in communication with the storage tank, the discharging chute is usually arranged on the ground higher than the storage tank, a sieve plate is arranged at the opening of the discharging chute, the aggregate is unloaded on the sieve plate in the discharging chute by the aggregate transport vehicle, the aggregate falls into the storage tank after being screened by the sieve plate, and the aggregate that does not meet the use requirement is left on the sieve plate. Before the next unloading, the operator needs to clean the aggregate left on the sieve plate, and then unload.

[0004] Since the aggregate left on the sieve plate cannot be utilized, the raw material is wasted. SUMMARY

[0005] In order to fully utilize the raw material and reduce the waste of raw material, the present application provides a concrete production system.

[0006] The concrete production system provided by the present application adopts the following technical scheme:

[0007] A concrete production system comprises an aggregate storage device, an aggregate conveying device, a powder storage device, a powder conveying device, a water material storage device, a water material conveying device and a mixing tank, wherein the aggregate storage device comprises a discharging chute, a sieve plate is arranged at the opening of the discharging chute, a collecting cage is fixed on one side of the sieve plate in the discharging chute, a plurality of elastic supporting members supporting the sieve plate are arranged in the discharging chute, and the extension end of the supporting member is fixed with the sieve plate.

[0008] A pushing assembly for pushing the screened material into the collecting cage is arranged on the sieve plate.

[0009] A broken plate is slidably connected in the collecting cage, the broken plate is located on the side of the collecting cage away from the sieve plate, and a plurality of sharp ends are arranged on the side of the broken plate close to the sieve plate.

[0010] A plurality of driving rods are hinged on the broken plate, and one end of the driving rod away from the broken plate is hinged on the sieve plate.

[0011] By adopting the above technical scheme, in the initial state, the upper surface of the sieve plate is not lower than the upper surface of the collecting cage, at this time, the end of the driving rod close to the sieve plate is not higher than the end of the driving rod close to the crushing plate; when discharging, the material falls on the sieve plate, the material moves downward by pressing the sieve plate, and the support member is compressed; as the material on the sieve plate gradually falls, the support member restores the deformation and pushes the sieve plate to move upward; when the sieve plate restores to the initial position, the material remaining on the sieve plate which does not meet the use requirement is pushed to the collecting cage by the pushing assembly for collection.

[0012] The sieve plate moves downward, and at the same time, the corresponding end of the driving rod is pulled to move downward, so that the driving rod rotates, the driving rod rotates and pulls the crushing plate to move in the direction close to the sieve plate, so that the crushing plate cooperates with the side wall of the collecting cage close to the sieve plate, thereby crushing the material falling into the collecting cage in the last time of discharging, and the material meeting the use requirement after crushing falls into the discharging groove, so that the raw material can be more fully utilized, and the waste of raw material is reduced.

[0013] Optionally, the support member comprises a sleeve fixedly connected to the lower surface of the sieve plate, a stand column is slidingly inserted into the sleeve, the lower end of the stand column is fixed to the groove bottom wall of the discharging groove, and the upper end of the stand column is fixedly connected to a support spring, and the upper end of the support spring is fixed to the inner bottom wall of the sleeve.

[0014] By adopting the above technical scheme, in the initial state, the support spring is in an incomplete compression state, when the sieve plate moves downward, the sieve plate compresses the support spring; as the material on the sieve plate gradually reduces, the support spring restores the deformation and pushes the sleeve and the sieve plate to move upward, so that the sieve plate is reset.

[0015] Optionally, a plurality of grooves are formed in the inner side walls of the two short sides of the collecting cage, the length direction of the grooves is arranged along the sliding direction of the crushing plate, a protrusion corresponding to the grooves is fixedly connected to the crushing plate, and each protrusion is slidingly inserted into the corresponding groove.

[0016] By adopting the above technical scheme, the grooves and the protrusions cooperate to slidingly connect the crushing plate and the collecting cage.

[0017] Optionally, the pushing assembly comprises a scraper above the sieve plate and a bottom rod below the sieve plate, a plurality of support plates are arranged between the scraper and the bottom rod, the support plates penetrate through the sieve plate and are slidingly inserted into the sieve plate, the support plates are fixed to the scraper and the bottom rod, a plurality of limiting springs are fixedly connected to the bottom rod, and the upper ends of the limiting springs abut against the sieve plate.

[0018] The two ends of the bottom rod are sleeved with a guide rail, and a connecting piece supporting the guide rail is further arranged in the discharging groove, the connecting piece is an elastic piece, and the extension end of the connecting piece is fixed to the guide rail.

[0019] The pushing assembly further comprises a driving piece driving the bottom rod to move along the length direction of the guide rail.

[0020] By adopting the above technical solution, in the initial state, the limiting spring is in a partially compressed state, and the scraper and the screen plate are in close contact with each other, with the scraper located on the side of the screen plate closer to the collection cage. When the screen plate moves downward, the screen plate first compresses the limiting spring. At this time, the connecting piece supports the bottom rod, causing the screen plate to move towards the bottom rod. The screen plate and the scraper lose contact and gradually move away from each other. As the screen plate continues to move downward, the connecting piece deforms, and at the same time, the driving piece drives the bottom rod and the scraper to move, causing the scraper to move to the side of the screen plate away from the collection cage.

[0021] As the material on the screen plate gradually decreases, the support component returns to its original shape and pushes the screen plate upward. At the same time, the limit spring returns to its original shape first, so that the screen plate contacts the scraper. As the screen plate continues to move, the connecting component returns to its original shape and cooperates with the support component, thereby pushing the screen plate to continue to move upward. While the screen plate moves upward, the drive component works to drive the scraper to move back to the initial position, thereby pushing the material on the screen plate that does not meet the usage requirements into the collection cage.

[0022] Optionally, the connector includes a guide cylinder fixedly connected to the guide rail, a connecting spring fixedly connected to the inner bottom wall of the guide cylinder, a connecting rod fixedly connected to the lower end of the connecting spring, the connecting rod being slidably inserted into the guide cylinder, and the lower end of the connecting rod being fixed to the bottom wall of the feeding trough.

[0023] An electromagnet is fixedly connected to the lower end face of the sleeve. The electromagnet is electrically connected to a power source. A distance sensor is provided on the column. A controller is also provided on one side of the feeding trough. The power sources of the distance sensor and the electromagnet are both electrically connected to the controller.

[0024] By adopting the above technical solution, during the downward movement of the screen plate, when the limiting spring is in a fully compressed state, as the screen plate continues to move downward, the screen plate drives the bottom rod, guide rail, and guide cylinder to move downward, thereby compressing the connecting spring. When the screen plate moves downward, the distance sensor detects the position of the electromagnet. When the screen plate moves to the lowest point, the distance sensor detects the electromagnet and transmits the signal to the controller. The controller controls the electromagnet to work, and the electromagnet is attracted to the column, thereby fixing the position of the screen plate and maintaining it for a period of time.

[0025] After a period of time, the controller disconnects the power to the electromagnet. At this time, the connecting spring and the support spring return to their original deformation and push the screen plate upward. The screen plate contacts the scraper, and then continues to move upward until it returns to its original position. The screen plate remains in its lowest position for a period of time, providing time for materials that meet the usage requirements to fall off the screen plate. This reduces the number of materials that meet the usage requirements remaining on the screen plate when the drive mechanism is working, thereby reducing the likelihood of the scraper pushing materials that meet the usage requirements into the collection cage.

[0026] Optionally, both the sleeve and the guide cylinder have rectangular cross-sections, and both the column and the connecting rod have internal cavities.

[0027] A rack is fixedly connected to one of the inner side walls of both the sleeve and the guide cylinder, and the rack is perpendicular to the sieve plate.

[0028] Both the column and the connecting rod have rotatably connected drive gears that mesh with racks in their cavities. One drive gear has a main rope sheave fixedly connected to it, and the cavity corresponding to the other drive gear has a driven gear that meshes with it. The driven gear has a secondary rope sheave fixedly connected to it.

[0029] Both the main and auxiliary winding sheaves are wound with pull ropes, and the ends of both pull ropes are fixed to the base rod.

[0030] By adopting the above technical solution, when the screen plate moves downward along the sleeve and guide cylinder, the sleeve and scraper move, driving the corresponding rack to move. The rack meshes with the corresponding driving gear, thereby driving the driving gear to rotate. The driven gear meshes with the corresponding driving gear, so the driven gear can rotate simultaneously. The driven gear rotates in the opposite direction to the other driving gear, so the main rope winding wheel and the auxiliary rope winding wheel rotate in opposite directions, causing one of the main rope winding wheel and the auxiliary rope winding wheel to wind the rope while the other releases the rope. The multiple ropes work together to drive the scraper to move, thus moving the scraper away from the collection cage. When the sleeve and guide cylinder move upward, the rotation directions of both the main rope winding wheel and the auxiliary rope winding wheel are opposite to their own rotation directions when the screen plate moves upward. At this time, the multiple ropes work together to drive the scraper to move closer to the collection cage.

[0031] Optionally, there are two supports, both located on the side of the sieve plate away from the collection cage. One end of the guide rail is slidably connected to the support, and the guide rail slides along the height direction of the support.

[0032] By adopting the above technical solution, the guide rail and the support component work together to make the guide rail more stable when it moves with the connecting component.

[0033] Optionally, a collar is fitted onto the sleeve, and the collar is fixedly connected to the guide rail.

[0034] By adopting the above technical solution, the collar and sleeve are matched to make the guide rail and sleeve slide together.

[0035] Optionally, the scraper is inclined, and in the initial state, the scraper blocks the opening of the collection cage.

[0036] By adopting the above technical solutions, the situation where materials that meet the usage requirements fall into the collection cage during material dumping is reduced.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. By setting up a sieve plate, support components, collection cage, crushing plate, and drive rod, the raw materials can be utilized more fully, reducing material waste;

[0039] 2. By incorporating a guide cylinder, connecting spring, connecting rod, distance sensor, electromagnet, and controller, the situation where the scraper pushes materials that meet the usage requirements into the collection cage is reduced.

[0040] 3. By setting up a rack, drive gear, driven gear, main winder, auxiliary winder, and pull rope, the scraper can be driven to move. Attached Figure Description

[0049] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0050] This application discloses a concrete production system. The concrete production system includes an aggregate storage device, a powder storage device, a water storage device, and a mixing tank. An aggregate conveying device is provided between the aggregate storage device and the mixing tank, a material distribution and conveying device is provided between the material distribution storage device and the mixing tank, and a water conveying device is provided between the water storage device and the mixing tank.

[0051] Reference Figure 1 and Figure 2 The aggregate storage device includes a storage tank and a discharge trough 1 connected to the storage tank. The discharge trough 1 is located underground, and a ring of fencing is provided around the discharge trough 1 on the ground. One side of the fencing is open to facilitate the dumping of aggregates into the discharge trough 1 by transport vehicles. A screen plate 2 and a collection cage 3 are provided at the opening of the discharge trough 1. The diameter of the screen holes on the collection cage 3 is the same as the diameter of the screen holes on the screen plate 2. The side walls of the screen plate 2 and the collection cage 3 are in contact with each other. The remaining side walls of the screen plate 2 and the collection cage 3 are in contact with the corresponding side walls of the discharge trough 1. The collection cage 3 is fixedly connected to the wall of the discharge trough 1.

[0052] Reference Figure 2 and Figure 3 In the feeding trough 1, there are multiple support members 4 located below the screen plate 2 for supporting the screen plate 2. The multiple support members 4 are all located on the side of the screen plate 2 away from the collection cage 3. In this embodiment, there are two support members 4, and the two support members 4 are evenly distributed at the two end corners of the side of the screen plate 2 away from the collection cage 3.

[0053] Reference Figure 3 and Figure 4 The support member 4 includes a sleeve 41, a support spring 42, and a column 43. Both the sleeve 41 and the column 43 have rectangular cross sections. The sleeve 41 is fixed on the lower surface of the screen plate 2 with its opening facing downward. One end of the support spring 42 is fixed to the column 43, and the other end of the support spring 42 is fixed to the inner bottom wall of the sleeve 41. The column 43 is slidably inserted into the sleeve 41, and the lower end of the column 43 is fixed to the bottom wall of the feed trough 1.

[0054] Reference Figure 1 and Figure 2 The feeding trough 1 is also provided with a pushing component 5 that pushes the material remaining on the screen plate 2 into the collection cage 3. The pushing component 5 includes a scraper 51, a connecting member 56 that supports the scraper 51, and a driving member 57 that drives the scraper 51 to move. The scraper 51 is located above the screen plate 2, and the length direction of the scraper 51 is set along the length direction of the collection cage 3. The scraper 51 is inclined and gradually tilts from bottom to top towards the collection cage 3.

[0055] Reference Figure 5 At least two support plates 511 are fixedly connected to the lower surface of the scraper 51. The support plates 511 are perpendicular to the sieve plate 2. Multiple support plates 511 are distributed along the length of the scraper 51. The sieve plate 2 has through holes that correspond one-to-one with the support plates 511. The length direction of the through holes is perpendicular to the length direction of the sieve plate 2. Each support plate 511 is slidably inserted into the corresponding through hole.

[0056] A bottom rod 52 is provided below the sieve plate 2. The length direction of the bottom rod 52 and the scraper 51 are the same. The upper surface of the bottom rod 52 is fixed to the lower surface of the support plate 511. Several limiting rods 54 perpendicular to the sieve plate 2 are slidably inserted on the bottom rod 52. A limiting spring 53 is sleeved on the limiting rod 54. The upper end of the limiting spring 53 is fixed to the upper end of the limiting rod 54 and abuts against the sieve plate 2. The lower end of the limiting spring 53 is fixed to the bottom rod 52. The elasticity of the limiting spring 53 is less than that of the supporting spring 42.

[0057] Reference Figure 3 and Figure 5 Both ends of the bottom rod 52 are provided with a U-shaped guide rail 55. The two guide rails 55 are located between the two sleeves 41. The length direction of the guide rail 55 is perpendicular to the length direction of the scraper 51. The two ends of the guide rail 55 are sealed. Each segment of the bottom rod 52 is slidably inserted into the corresponding guide rail 55. A collar 551 is fixedly connected to the side wall of the guide rail 55 near the sleeve 41. The collar 551 is sleeved on the corresponding sleeve 41 and slidably inserted into the sleeve 41.

[0058] Reference Figure 2 and Figure 6 There are two connectors 56. The connectors 56 are located below the end of the guide rail 55 near the collection cage 3. The connectors 56 include a guide cylinder 561 fixedly connected to the lower surface of the bottom rod 52. A connecting spring 562 is fixedly connected to the inner bottom wall of the guide cylinder 561. A connecting rod 563 is fixedly connected to the lower end of the connecting spring 562. The connecting rod 563 is slidably inserted into the guide cylinder 561. The cross-sections of the guide cylinder 561 and the connecting rod 563 are both rectangular.

[0059] Reference Figure 1 and Figure 3 The connector 56 also includes an electromagnet 564 fixedly connected to the lower surface of the sleeve 41. The electromagnet 564 is ring-shaped and is sleeved on the corresponding column 43. The electromagnet 564 is electrically connected to the power supply. A distance sensor 565 is installed at the lower end of one side wall of the column 43. The distance sensor 565 detects the position of the electromagnet 564. A controller 566 is installed on one side of the feeding trough 1. The power supply of the electromagnet 564 and the distance sensor 565 are both electrically connected to the controller 566.

[0060] When the sieve plate 2 moves to the lowest position, the distance sensor 565 detects the height of the electromagnet 564 and transmits the data to the controller 566. The controller 566 controls the power supply to turn on, thereby controlling the electromagnet 564 to work, so that the sieve plate 2 is kept at the lowest position for a period of time, providing time for the material that meets the usage requirements to fall on the sieve plate 2.

[0061] Reference Figure 4 and Figure 6 Both the column 43 and the connecting rod 563 are hollow inside. The driving component 57 includes a sleeve 41 and a guide cylinder 561, both of which are fixedly connected to a rack 571 on their inner side walls. The rack 571 is perpendicular to the screen plate 2. Both the column 43 and the connecting rod 563 have holes on their side walls that communicate with their own interiors. Each rack 571 is inserted into a corresponding hole. Both the column 43 and the connecting rod 563 are rotatably connected to a drive gear 572 that meshes with the rack 571.

[0062] A main windlass 574 is fixedly connected to the rotating shaft of the drive gear 572 corresponding to the column 43. The main windlass 574 is located outside the column 43. A slotted hole is provided on the side wall of the sleeve 41 corresponding to the main windlass 574 to allow the rotating shaft of the main windlass 574 to move. A driven gear 573 that meshes with the drive gear 572 is rotatably connected to the connecting rod 563. A secondary windlass 575 is fixedly connected to the rotating shaft of the driven gear 573. The secondary windlass 575 is located outside the connecting rod 563. A slotted hole is also provided on the side wall of the guide cylinder 561 corresponding to the secondary windlass 575 to allow the rotating shaft of the secondary windlass 575 to move. A pull rope 576 is wound around each main windlass 574 and each secondary windlass 575. The end of the pull rope 576 is fixed to the end of the base rod 52 corresponding to it.

[0063] In the initial state, the support spring 42 and the limit spring 53 are in the initial state, the upper surface of the screen plate 2 is flush with the upper surface of the collection cage 3, the scraper 51 is located on the side of the screen plate 2 near the collection cage 3, each pull rope 576 is taut, the upper side of the scraper 51 is in contact with the side wall of the feed chute 1 near the collection cage 3, and the scraper 51 blocks the opening at the upper end of the collection cage 3; the lower surface of the scraper 51 is in contact with the upper surface of the screen plate 2, and there is a gap between the upper surface of the bottom plate and the lower surface of the scraper 51.

[0064] When unloading, the material falls onto the screen plate 2. At this time, the scraper 51 guides the material, causing the material falling above the collection cage 3 to slide along the scraper 51 onto the screen plate 2, reducing the amount of qualified material falling into the collection cage 3. Simultaneously, the material presses the screen plate 2 downward, and the screen plate 2 drives the sleeve 41 downward, thereby compressing the limit spring 53. While the screen plate 2 is moving, it first compresses the limit spring 53. As the screen plate 2 continues to move downward, the distance between the upper surface of the scraper 51 and the upper surface of the screen plate 2 gradually increases, so that the material is located between the scraper 51 and the screen plate 2.

[0065] When the limit spring 53 is compressed to its limit, as the screen plate 2 continues to move downward, the screen plate 2 moves downward along the sleeve 41, the bottom rod 52, the guide rail 55, and the guide cylinder 561, thereby compressing the support spring 42 and the connecting spring 562. The sleeve 41 and the guide cylinder 561 both drive the corresponding rack 571 to move downward. The movement of the rack 571 drives the corresponding drive gear 572 to rotate. At the same time, the driven gear 573 meshes with the corresponding drive gear 572 and also rotates. The direction of rotation of the driven gear 573 is opposite to the direction of rotation of the drive gear 572. The rotation directions of the main winding sheave 574 and the auxiliary winding sheave 575 are also opposite.

[0066] The rotation of the main winding sheave 574 causes the pull rope 576 to wind further around the main winding sheave 574, while the rotation of the auxiliary winding sheave 575 releases the pull rope 576. The pull rope 576 on the main winding sheave 574 and the auxiliary winding sheave 575 work together to pull the bottom rod 52, the support plate 511, and the scraper 51 away from the collection cage 3. When the screen plate 2 moves to the lowest position, the distance sensor 565 detects the position of the electromagnet 564 and transmits the signal to the controller 566. The controller 566 controls the power to be turned on, the electromagnet 564 is energized and attracts to the column 43, thereby fixing the position of the sleeve 41 and the screen plate 2.

[0067] When the screen plate 2 moves to the lowest position, the scraper 51 is located on the side of the screen plate 2 away from the collection cage 3 under the action of the pull rope 576. After a period of time, the materials that meet the specifications on the screen plate 2 fall into the feed trough 1. The controller 566 controls the power supply of the electromagnet 564 to be disconnected. At this time, the electromagnet 564 loses its magnetism, the support spring 42 restores its deformation and pushes the sleeve 41 and the screen plate 2 to move upward. At the same time, the limit spring 53 also restores its deformation, so that the screen plate 2 contacts the scraper 51.

[0068] When both the sleeve 41 and the guide cylinder 561 move upward, the sleeve 41 and the guide cylinder 561 drive the corresponding rack 571 to move upward. The movement of the rack 571 drives the corresponding drive gear 572 to rotate. The driven gear 573 also rotates under the action of the corresponding drive gear 572, thereby causing the main winding rope wheel 574 and the auxiliary winding rope wheel 575 to rotate. This causes the pull rope 576 to drive the scraper 51 to move towards the collection cage 3. As the scraper 51 moves, it pushes the material on the screen plate 2 to move. When the scraper 51 returns to its initial position, the material on the scraper 51 falls into the collection cage 3.

[0069] Reference Figure 5 and Figure 7 The collection cage 3 is also equipped with a crushing component 6 for crushing materials. The crushing component 6 includes a crushing plate 61 disposed in the collection cage 3. The length direction of the crushing plate 61 is arranged along the length direction of the collection cage 3. The side wall of the crushing plate 61 near the screen plate 2 is provided with multiple sharp points. Multiple protrusions 62 are fixedly connected to the two short side walls of the crushing plate 61. The multiple protrusions 62 are arranged along the height direction of the crushing plate 61. The inner side walls of the two short sides of the collection cage 3 are provided with grooves 31 that correspond one-to-one with the protrusions 62. The length direction of the grooves 31 is arranged along the width direction of the collection cage 3. Each protrusion 62 is slidably inserted into the corresponding groove 31.

[0070] Several drive rods 63 are hinged to the side wall of the crushing plate 61 near the screen plate 2. The end of the drive rod 63 away from the crushing plate 61 is hinged to the screen plate 2. In the initial state, the drive rod 63 is parallel to the screen plate 2. The collection cage 3 has a hole on the side wall near the screen plate 2 for the drive rod 63 to move. In this embodiment, there are two drive rods 63, which are evenly distributed on the crushing plate 61. In other embodiments, there may be only one drive rod 63. When there is only one drive rod 63, the drive rod 63 is located in the middle of the crushing plate 61.

[0071] When the screen plate 2 moves downward, the movement of the screen plate 2 drives the corresponding end of the drive rod 63 to move downward, thereby causing the drive rod 63 to rotate. At the same time, the screen plate 2 drives the drive rod 63 and the crushing plate 61 to move closer to the screen plate 2, so that the crushing plate 61 cooperates with the side wall of the collection cage 3 near the screen plate 2, thereby crushing the material in the collection cage 3. When the screen plate 2 moves upward, the screen plate 2 drives the drive rod 63 to move, so that the drive rod 63 pushes the crushing plate 61 to move away from the screen plate 2, thereby resetting the crushing plate 61.

[0072] Each time the screen plate 2 moves downward, the crushing plate 61 crushes the material in the collection cage 3. The material that meets the usage requirements falls into the feed chute 1 through the screen holes on the collection cage 3, which can make fuller use of the raw materials and reduce the waste of raw materials.

[0073] During production, the aggregate conveying device, powder conveying device, and water conveying device all work, thereby feeding a certain amount of aggregate, powder, and water into the mixing tank. The mixing tank works to mix the aggregate, powder, and water to form concrete.

[0074] The implementation principle of a concrete production system according to an embodiment of this application is as follows: When the operator pours material onto the screen plate 2, the material moves the screen plate 2 downwards. The screen plate 2 drives the crushing plate 61 to move via the drive rod 63. At the same time, the screen plate 2 compresses the limit spring 53, causing the screen plate 2 to disengage from the scraper 51. The screen plate 2 continues to move downwards and drives the main winding rope wheel 574 and the auxiliary winding rope wheel 575 to rotate via the rack 571, the drive gear 572, and the driven gear 573. This drives the scraper 51 to move away from the collection cage 3 via the pull rope 576. When the screen plate 2 moves to the lowest point, the controller 566 controls the electromagnet 564 to work and fix the position of the screen plate 2. At this time, the crushing plate 61 and the collection cage 3 cooperate to crush the material. The crushed material that meets the usage requirements falls into the discharge trough 1.

[0075] After a period of time, the controller 566 controls the power supply of the electromagnet 564 to be disconnected. At this time, the support spring 42, the connecting spring 562 and the limit spring 53 resume their deformation, thereby causing the screen plate 2 to contact the scraper 51, and causing the main winding wheel 574 and the auxiliary winding wheel 575 to work. At this time, the scraper 51 pushes the material on the screen plate 2 into the collection cage 3. When the next material is fed, the screen plate 2 drives the drive rod 63 and the crushing plate 61 to move, thereby crushing the material in the collection cage 3 again.

[0076] During production, the aggregate conveying device, powder conveying device, and water conveying device operate to deliver aggregates, powders, and water into the mixing tank. The mixing tank mixes the various materials in the tank to form concrete.

[0077] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
