DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] Please see the attached Figure 1 An embodiment of the present invention provides a dry-mix mortar production device with environmentally friendly machine-made sand, comprising a raw material bin 1, a vibrating screen 2 being provided at the bottom end of the raw material bin 1, a belt conveyor 3 being provided at one end of the vibrating screen 2, a screw conveyor 4 being provided at one side of the belt conveyor 3, a double-shaft zero-gravity mixer 5 being provided at one end of the belt conveyor 3 and the screw conveyor 4, and a packaging device 6 being provided at one end of the double-shaft zero-gravity mixer 5, the raw material bin 1 comprising a machine-made sand bin, a cement bin being provided at one side of the machine-made sand bin, an additive bin being provided at one side of the cement bin, the bottom end of the machine-made sand bin being provided above the vibrating screen 2, the outlet of the machine-made sand bin being provided above the belt conveyor 3, and the outlets of the cement bin and the additive bin being provided above the screw conveyor 4.

[0028] Specifically, the raw material bin 1 serves as a storage unit, and the machine-made sand bin, cement bin, and additive bin inside it are used to store three types of raw materials of different properties: machine-made sand, cement, and additives. The bottom opening of the machine-made sand bin faces the feeding area of ​​the vibrating screen 2. When a certain amount of machine-made sand is stored, it will continue to fall into the vibrating screen 2 under the action of its own gravity. The vibrating screen 2 uses the exciting force generated by the vibration motor to make the screen vibrate periodically. The mesh size of the screen is used to screen the machine-made sand that has fallen in, and the machine-made sand particles that do not meet the particle size requirements are screened out, and the machine-made sand with a particle size that meets the production needs is screened out. After screening, the machine-made sand naturally falls onto the conveyor belt of the belt conveyor 3 due to the action of gravity. The conveyor belt of the belt conveyor 3 is driven by the active roller and the driven roller to rotate in a circular motion. Relying on the friction between the conveyor belt and the machine-made sand, the machine-made sand is continuously transported to the feeding end of the dual-axis zero-gravity mixer 5.

[0029] The outlets of the cement and additive silos are designed to face the feed port of screw conveyor 4. Powdered or granular raw materials, such as cement and additives, automatically fall into the trough of screw conveyor 4 under the influence of their own gravity. The trough of screw conveyor 4 is equipped with spiral blades, which are driven by a motor to rotate. During rotation, the spiral blades push the cement and additives in the trough along the conveying direction of screw conveyor 4, ultimately delivering the cement and additives to the feed port of the dual-shaft zero-gravity mixer 5. This, in conjunction with the machine-made sand conveying process, ensures that all raw materials enter the mixer in an orderly manner according to the production rhythm.

[0030] The feeding end of the twin-shaft zero-gravity mixer 5 receives machine-made sand from the belt conveyor 3, and cement and additives conveyed by the screw conveyor 4. The internal structure of the twin-shaft zero-gravity mixer 5 is a twin-shaft layout, and specially shaped mixing blades are installed on the two mixing shafts 515. When the motor drives the twin shafts to rotate, the mixing blades rotate with the shafts. During the rotation process, the mixing blades throw the material upward, causing the material to form a weightless state inside the mixer. In this state, the material will be thrown and convected in all directions in the machine, and different raw materials will constantly intersperse and merge with each other, thereby achieving a sufficient and uniform mixing process of machine-made sand, cement, and additives, and finally forming a dry-mixed mortar with uniform composition.

[0031] After being thoroughly mixed by the dual-shaft zero-gravity mixer 5, the dry-mixed mortar is conveyed through the mixer's discharge mechanism to the feeding station of the packaging device 6. The packaging device 6 is equipped with a metering system, a packaging container conveying system, and a sealing mechanism. The metering system accurately weighs the dry-mixed mortar according to the preset packaging weight. The packaging container conveying system transports empty packaging containers (such as bags) to the designated filling position. The filling mechanism then pours the weighed dry-mixed mortar into the packaging container, and the sealing mechanism seals the filled packaging container, completing the entire dry-mixed mortar production process from production to finished product packaging.

[0032] Raw materials are sorted and stored in a raw material silo 1, machine-made sand is screened and sized to ensure particle size by a vibrating screen 2, conveyed by a belt conveyor 3 and a screw conveyor 4 based on material properties, and a dual-shaft zero-gravity mixer 5 achieves efficient and uniform mixing of the raw materials using zero-gravity mixing. Finally, a packaging device 6 completes standardized packaging of the finished product. These components work in tandem to achieve continuous production of dry-mix mortar with environmentally friendly machine-made sand, ensuring stable product quality and producing uniform dry-mix mortar products. This solves the problem of poor integration between various links in dry-mix mortar production, which makes continuous and stable production difficult.

[0033] Please see the attached Figure 1 -Attached Figure 5 The double-shaft zero-gravity mixer 5 includes a shell 51, and sliding cavities are provided on both sides of the shell 51. A stirring chamber 517 is provided inside the shell 51, and a support plate 510 is provided on one side of the shell 51. A reciprocating mechanism is provided on the upper surface of the support plate 510, and a motor 1 512 is provided on the top of the reciprocating mechanism. A rotating shaft is fixedly provided at the output end of the motor 1 512, and a gear 2 524 is provided on the outer wall of the rotating shaft. The outer wall of the rotating shaft passes through the gear 2 524 and is provided on the outer wall of the shell 51. The tooth end of the gear 2 524 is symmetrically meshed with the gear 1 523, and a stirring shaft 515 is provided in the middle of the gear 1 523. The stirring shaft 515 is provided in the stirring chamber 517 of the shell 51, and movable plates 56 are provided at both ends of the middle of the stirring shaft 515. The outer wall of the movable plate 56 is slidably connected to the outer wall of the shell 51 through the sliding cavity. The outer wall of the stirring shaft 515 is provided with a plurality of fixed rods 521, and one end of the fixed rod 521 is provided with a stirring scraper 520.

[0034] Specifically, motor 1 512 serves as the power source, with its output end fixedly connected to the rotating shaft. When motor 1 512 is started, the rotating shaft rotates synchronously with the motor output shaft. Gear 2 524, mounted on the outer wall of the rotating shaft, rotates with the rotating shaft. Because the tooth ends of gear 2 524 symmetrically mesh with gear 1 523, according to the principle of gear meshing transmission, when gear 2 524 rotates, it drives the two gears 1 523 to rotate in opposite directions and synchronously. A stirring shaft 515 is mounted in the middle of gear 1 523. Driven by gear 1 523, stirring shaft 515 rotates within the stirring chamber 517 of the housing 51, providing power for material agitation.

[0035] As the stirring shaft 515 rotates, several fixed rods 521 mounted on its outer wall rotate accordingly. Driven by the fixed rods 521, the stirring scrapers 520 at one end of the fixed rods 521 stir the material in the stirring chamber 517. Movable plates 56 are mounted at both ends of the central portion of the stirring shaft 515. The outer walls of the movable plates 56 are slidably connected to the outer wall of the housing 51 via a sliding cavity. Driven by a reciprocating mechanism, the movable plates 56 reciprocate along the sliding cavity, thereby driving the stirring shaft 515 to rotate and simultaneously move back and forth along the sliding cavity of the housing 51. This allows the stirring scrapers 520 to stir the material over a wider range, enabling more thorough stirring and mixing of the material at different locations within the stirring chamber 517.

[0036] Motor 1 512 drives the agitator shaft 515 through gear transmission, which in turn rotates. The reciprocating mechanism allows the agitator shaft 515 to perform both rotational and reciprocating motions. The agitator scraper 520 performs a combined motion with the agitator shaft 515, enabling all-around, multi-dimensional mixing of the materials within the agitator chamber 517. This improves the uniformity and efficiency of material mixing, ensuring the full integration of the various raw materials in the dry-mix mortar and ensuring the quality of the dry-mix mortar product. This addresses the problem of the agitator shaft 515 in conventional mixers having a single motion form.

[0037] Please see the attached Figure 2 , Attachment Figure 5 -Attached Figure 6 The reciprocating mechanism includes a motor 2 529, the bottom end of the motor 2 529 is arranged on the upper surface of the support plate 510, and a pulley 2 528 is fixedly provided at the output end of the motor 2 529. A belt 527 is connected to the inside of the pulley 2 528, and a pulley 1 526 is provided at one end of the belt 527. A reciprocating screw rod 513 is provided in the middle of the pulley 1 526, and blocks 525 are provided at both ends of the reciprocating screw rod 513. The bottom end of the block 525 is arranged on the upper surface of the support plate 510, and the outer wall of the reciprocating screw rod 513 is threadedly connected with 511. The top end of 511 is arranged at the bottom end of the motor 1 512, and a slide groove 534 is provided on the upper surface of the support plate 510. 511 is slidably connected to the upper surface of the support plate 510 through the slide groove 534.

[0038] Specifically, motor 2 529 serves as the power source of the reciprocating mechanism and is mounted on the upper surface of the support plate 510. When motor 2 529 is started, pulley 2 528 fixedly connected to its output end begins to rotate. Pulley 2 528 is connected to pulley 1 526 via belt 527. According to the transmission principle of belt 527, when pulley 2 528 rotates, the friction force of belt 527 drives pulley 1 526 to rotate synchronously. A reciprocating screw 513 is provided in the middle of pulley 1 526, so that the reciprocating screw 513 rotates with the rotation of pulley 1 526. Stoppers 525 are provided at both ends of the reciprocating screw 513. The bottom ends of the stoppers 525 are fixed to the upper surface of the support plate 510. The stoppers 525 serve to limit the axial movement of the reciprocating screw 513, ensuring that it can only perform stable rotational motion around its own axis.

[0039] Slider 511, threadedly connected to the outer wall of reciprocating screw 513, moves linearly along the axial direction of the screw when reciprocating screw 513 rotates due to the helical transmission characteristics of the screw thread. Furthermore, a slide groove 534 is provided on the upper surface of support plate 510, through which slider 511 is slidably connected to support plate 510. Slide groove 534 guides and limits slider 511, ensuring the directional accuracy of slider 511 during linear motion, allowing it to slide smoothly only in the direction defined by slide groove 534.

[0040] The top end of the slider 511 is connected to the bottom end of the motor 1 512, so when the slider 511 performs linear reciprocating motion, it will drive the motor 1 512 and the rotating shaft connected to the motor 1 512, the stirring shaft 515 and other components to perform corresponding reciprocating motion, so that the stirring shaft 515 can rotate and stir the material while also moving back and forth in the sliding cavity of the shell 51, thereby achieving a more complex and comprehensive stirring action.

[0041] Motor 2 529 drives pulley 2 528 , which in turn drives pulley 1 526 and reciprocating screw 513 via belt 527 . The threaded connection between the screw and the slider, and the sliding fit between the slider and the chute 534, enable reciprocating motion of motor 1 512 and the stirring member. This allows stirring shaft 515 to achieve both rotational and reciprocating mixing, expanding the mixing dimension and range, improving the uniformity and adequacy of material mixing, and contributing to improved dry-mix mortar product quality. This solves the problem of incomplete material mixing and localized uneven mixing caused by the movement of stirring shaft 515 .

[0042] Please see the attached Figure 1 -Attached Figure 4 A hopper 55 is provided on the upper surface of the shell 51 , and a dust suction mechanism is provided on one side of the hopper 55 . The dust suction mechanism is provided on the upper surface of the shell 51 .

[0043] Specifically, a hopper 55 is provided on the upper surface of the housing 51. Hopper 55 is used to receive the various raw materials required for dry-mix mortar production. A dust collection mechanism is located on one side of the hopper 55, on the upper surface of the housing 51. When raw materials are added to the hopper 55, the falling and tumbling of the materials will cause some dust to rise and disperse within the hopper 55 and the housing 51. The dust collection mechanism collects this dust.

[0044] Please see the attached Figure 1 -Attached Figure 4 The dust collection mechanism includes an exhaust fan 52, which is arranged on the upper surface of the shell 51 through a machine base. A dust collection pipe 53 is fixedly provided at the input end of the exhaust fan 52, and a through pipe 532 is provided on the outer wall of the dust collection pipe 53 passing through the shell 51. A dust collection nozzle 533 is provided on the outer wall of the through pipe 532. A dust outlet pipe 54 is fixedly provided at the output end of the exhaust fan 52, and a dust collecting box 514 is provided at one end of the dust outlet pipe 54. One side of the dust collecting box 514 is provided on the side wall of the shell 51, and a discharging mechanism is provided at the bottom end of the shell 51.

[0045] Specifically, the exhaust fan 52 is fixed to the upper surface of the housing 51 via a base and serves as the power source for the dust collection mechanism. When the exhaust fan 52 is activated, its internal impeller rotates at high speed, creating a negative pressure area at the input end of the exhaust fan 52. The input end of the exhaust fan 52 is fixedly connected to the dust collection pipe 53. This negative pressure is transmitted through the dust collection pipe 53 to the through pipe 532 connected to the dust collection pipe 53 and the dust collection nozzle 533 located on the outer wall of the through pipe 532, forming a negative pressure environment around the dust collection nozzle 533.

[0046] During the dry-mix mortar production process, dust generated when raw materials are added to the hopper 55 is sucked into the dust nozzle 533 due to the negative pressure around the dust nozzle 533. The dust nozzle 533 is connected to the through pipe 532, which is in turn connected to the dust pipe 53. Therefore, the dust passes through the dust nozzle 533 and the through pipe 532 in sequence and enters the dust pipe 53, and is then transported to the input end of the exhaust fan 52.

[0047] Dust-laden air entering the input end of the exhaust fan 52 gains kinetic energy from the impeller of the exhaust fan 52 and is transported to the output end of the exhaust fan 52. A dust outlet pipe 54 is fixedly connected to the output end of the exhaust fan 52, through which the dust-laden air enters. One end of the dust outlet pipe 54 is connected to a dust collection box 514, which is located on the side wall of the housing 51. The dust-laden air is transported along the dust outlet pipe 54 into the dust collection box 514, completing the dust collection process.

[0048] Negative pressure is generated by exhaust fan 52, sucking dust through suction pipe 53, through tube 532, and suction nozzle 533. Dust is then sent to dust box 514 for filtration and collection via dust outlet pipe 54. This effectively reduces dust concentration, minimizing health hazards to operators and preventing dust accumulation from affecting equipment, thereby ensuring equipment life and stable operation, and improving the safety and cleanliness of the production environment. This solves the problem of dust flying during raw material addition in dry-mix mortar production, which poses a health hazard to operators.

[0049] Please see the attached Figure 1 , Attachment Figure 3 -Attached Figure 4 , Attachment Figure 8 The discharge mechanism includes two fixed plates 530, one end of the fixed plate 530 is rotatably connected to the discharge plate 531 through a hinge 522, and a hinge seat 2 535 is provided in the middle of the discharge plate 531, one end of the hinge seat 2 535 is provided with an electric push rod 519, one end of the electric push rod 519 is provided with a hinge seat 1 518, and one end of the hinge seat 1 518 is provided with a moving mechanism.

[0050] Specifically, the discharge mechanism includes two fixed plates 530, which are fixedly mounted at the bottom of the housing 51 and serve as a foundation for supporting and securing the relevant components. One end of each fixed plate 530 is pivotally connected to a discharge plate 531 via a hinge 522, allowing the discharge plate 531 to rotate relative to the fixed plate 530 about the axis of the hinge 522, thereby achieving opening and closing, and controlling the discharge of material.

[0051] A hinged seat 2 535 is provided in the middle of the blanking plate 531. It is primarily used to connect to one end of the electric push rod 519, providing a connection point for mounting and applying force to the push rod 519. The other end of the push rod 519 is provided with a hinged seat 1 518, which secures this end of the push rod 519 to the moving mechanism, ensuring that the push rod 519 can function stably during operation and that its own telescopic movement drives the connected blanking plate 531 to rotate about the hinge 522.

[0052] When unloading is required, the electric push rod 519 is activated, causing it to extend and retract. One end of the electric push rod 519 is fixed via hinged seat 1 518, and the other end is connected to the blanking plate 531 via hinged seat 2 535. As the push rod extends or retracts, it applies a corresponding push or pull force to the blanking plate 531. Based on the lever principle and the characteristics of the rotational connection, the blanking plate 531 rotates accordingly around the axis of the hinge 522.

[0053] The electric push rod 519 is normally in an extended state. In this state, the electric push rod 519 presses against the blanking plate 531, causing the blanking plate 531 to be in a closed state. At this time, the material in the mixing chamber 517 cannot flow out. When the material discharge operation is required, the electric push rod 519 is activated to retract it. Since one end of the electric push rod 519 is fixed by hinge seat 1 518 and the other end is connected to the blanking plate 531 by hinge seat 2 535, a pulling force is applied to the blanking plate 531 during the process of the push rod retraction. Based on the lever principle and the characteristics of the rotational connection, the blanking plate 531 will rotate downward around the axis of the hinge 522, and the blanking port that was originally in a closed state will open. The mixed dry-mixed mortar and other materials in the mixing chamber 517 can then flow downward along the opened blanking plate 531 to achieve material discharge.

[0054] By leveraging the extension and retraction of electric push rod 519, in conjunction with hinged seat 1 518, hinged seat 2 535, and hinge 522, the rotation angle of blanking plate 531 is precisely controlled, allowing for flexible opening and closing of the discharge port, enabling on-demand quantitative discharge of materials, thus avoiding material waste and process disruption. This simple and reliable operation ensures stable discharge operation and meets the material supply requirements of subsequent processes. This solves the problems of traditional discharge methods, such as difficulty in precisely controlling the discharge volume, inflexible opening and closing of the discharge port, and inconvenient operation.

[0055] Please see the attached Figure 1 -Attached Figure 4 The moving mechanism includes several legs 57, the top of the leg 57 is set on the lower surface of the fixed plate 530, a reinforcement rod 516 is set on one side of the leg 57, and a cross bar 59 is set on the other side of the leg 57. The upper surface of the cross bar 59 is set on the bottom end of the hinge seat 518, and the bottom end of the leg 57 is provided with a universal wheel 58.

[0056] Specifically, the mobile mechanism utilizes several legs 57 as its primary support components. The top ends of the legs 57 are fixedly connected to the lower surface of the fixed plate 530, providing a stable vertical support for the entire dry-mix mortar production equipment and ensuring that the equipment can be stably placed on an operating surface such as the ground. A reinforcement rod 516 is provided on one side of the legs 57, with each end of the reinforcement rod 516 connected to an adjacent leg 57. This enhances the overall structural stability of the legs 57, enabling them to better withstand the weight of the equipment and various forces generated during operation, and preventing the legs 57 from shaking or deforming.

[0057] A crossbar 59 is provided on the other side of the support leg 57. The upper surface of the crossbar 59 is connected to the bottom end of the hinge seat 518. This crossbar 59 not only serves to assist in supporting the hinge seat 518, but also further strengthens the connection between the support legs 57, making the entire support structure more solid. Universal wheels 58 are mounted on the bottom ends of the support legs 57. Universal wheels 58, through their inherent rotational structure, can rotate freely in different directions, giving the equipment flexible steering capabilities on the ground.

[0058] When the entire dry-mix mortar production equipment needs to be moved, the operator can apply external force to the equipment. At this time, the universal wheels 58 installed at the bottom of the legs 57 will roll on the ground. Because the universal wheels 58 can flexibly turn, the equipment can be moved along any desired path based on the direction of the external force and the rotation of the universal wheels 58. Whether adjusting the position of the equipment within the workshop or transferring the equipment to another suitable production site, these operations can be conveniently achieved with the help of the universal wheels 58. During the movement, the stable support structure formed by the reinforcement rods 516, crossbars 59 and legs 57 ensures the overall stability of the equipment, preventing problems such as the equipment tipping over and loose components due to movement.

[0059] With support from legs 57, enhanced stability from reinforcement rods 516, auxiliary support and enhanced connection from crossbars 59, and flexible steering and rolling from universal wheels 58, the dry-mix mortar production equipment is easily movable, facilitating position adjustment, connecting production links, and smoothly transferring sites, reducing labor and material consumption and improving flexibility and convenience. This solves the problem of difficult position adjustment and inconvenient movement of dry-mix mortar production equipment.

[0060] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
