Through the control of the computer host, the material box 4 can move according to the set motion trajectory.

[0034] Furthermore, the vibrating device 5 is used to vibrate the concrete material;

[0035] The vibrating device 5 includes a motor 501, which is installed on the top of the material box 4. A support frame 507 is installed on the bottom inner wall of the material box 4. A reciprocating screw rod 502 is rotatably installed on the support frame 507. The reciprocating screw rod 502 penetrates the top of the material box 4 and is rotatably connected to the top of the material box 4. A ball slide 503 is slidably installed inside the material box 4. Two mounting arms 504 are connected to the ball slide 503. A plurality of vibration rods 505 are installed on the mounting arms 504.

The plurality of vibration rods 505 are respectively connected to the four sawtooth plates 506. 6, the vibration rod 505 contacts the surface of the serrated plate 506 during the up and down movement, so that the vibration rod 505 is driven by the serrated surface of the serrated plate 506 to vibrate, and multiple vibration rods 505 contact the concrete material in the material box 4 during the movement, and transmit the vibration to the concrete material, so as to vibrate and compact the concrete material. Through the setting of the vibrating device 5, the multiple vibration rods 505 can also vibrate during the up and down reciprocating movement. When vibrating, the multiple vibration rods 505 can vibrate and compact the concrete material inside the material box 4, thereby improving the density of the concrete material.

[0036] Furthermore, a reciprocating threaded groove is provided on the reciprocating screw 502, and the inner wall of the ball slide 503 is slidably connected to the reciprocating threaded groove on the reciprocating screw 502 through the ball, and the end of the mounting arm 504 away from the ball slide 503 is slidably connected to the inner wall of the material box 4.

Through the cooperation of the reciprocating screw 502 and the ball slide 503, the two mounting arms 504 can drive the multiple vibration rods 505 to reciprocate up and down in the material box 4, thereby increasing the contact area between the multiple vibration rods 505 and the concrete material, so that concrete of different depths in the material box 4 can be vibrated and compacted, thereby improving the vibration and compaction effect.

[0037] In addition, a discharging device 6 is provided for stacking concrete materials;

[0038] The discharge device 6 includes a discharge pipe 601, which is installed at the bottom of the material box 4. The bottom of the discharge pipe 601 is connected to a discharge head 603, and a plurality of discharge holes are arranged on the discharge head 603. The concrete material in the material box 4 falls into the discharge pipe 601 by gravity, and the concrete material in the discharge pipe 601 is discharged through the plurality of discharge holes on the discharge head 603. The material box 4 moves continuously during this process, so that the discharge head 603 moves with the material box 4, and the concrete material is stacked layer by layer according to the set motion trajectory.

[0039] In addition, the top of the discharge head 603 is rotatably connected to a spiral blade shaft 602, the top of the spiral blade shaft 602 is connected to the bottom of the reciprocating screw 502, and the spiral blade shaft 602 is provided with spiral blades. The reciprocating screw 502 drives the spiral blade shaft 602 to rotate when rotating. The spiral blades on the spiral blade shaft 602 can squeeze the concrete material in the discharge pipe 601 downward, so that the concrete material can be discharged from the discharge head 603 more evenly to avoid blockage. Through the setting of the discharge device 6, the spiral blade shaft 602 can continuously squeeze the concrete material in the discharge pipe 601 downward by rotating, and the concrete material is extruded through the discharge head 603, so that the flow rate and rate of extrusion of the concrete material are more uniform, thereby improving the operation quality.

[0040] It is worth noting that two mounting rods 604 are connected to the bottom of the reciprocating screw rod 502, and a scraper 605 is connected to one end of the mounting rod 604 away from the reciprocating screw rod 502. The two scraper strips 605 are in contact with the inner wall of the discharge pipe 601. When the reciprocating screw rod 502 rotates, the two scraper strips 605 are driven to rotate through the two mounting rods 604. The connection between the discharge pipe 601 and the material box 4 is set in a funnel shape to facilitate the falling of the concrete material in the material box 4. The two scraper strips 605 continuously scrape the funnel-shaped inner wall of the discharge pipe 601 during the rotation process. The concrete material is promoted to fall, and part of the concrete material is prevented from being attached to the connection between the material box 4 and the discharge pipe 601 for a long time and solidifying, thereby affecting the fluidity of the subsequent concrete material. The two scraping bars 605 are arranged so that the two scraping bars 605 can continuously scrape off the concrete material attached to the inner wall of the discharge pipe 601 through rotation, so as to prevent part of the concrete here from solidifying due to long-term attachment, thereby affecting the passability of the subsequent concrete material in the discharge pipe 601, and finally affecting the overall fluidity of the concrete material.

[0041] It is worth noting that the feeding device 7 is used to add early setting agent;

[0042] The feeding device 7 includes a medicine box 701, which is installed on the side wall of the material box 4. The medicine box 701 is filled with an early-setting agent. An air bag 702 is installed on the top inner wall of the material box 4. One of the mounting arms 504 contacts the air bag 702 during movement. An air pipe 703 is connected between the air bag 702 and the medicine box 701. A liquid adding ring 705 is connected to the outer wall of the feed pipe 601. A liquid pipe 704 is connected between the liquid adding ring 705 and the medicine box 701. The mounting arm 504 below the air bag 702 contacts and squeezes the air bag 702 during the upward movement. After the air bag 702 is squeezed, air is injected into the medicine box 701 through the air pipe 703. The medicine box 701 uses the positive pressure principle to transport the early-setting agent to the liquid adding ring 705 through the liquid pipe 704.

[0043] Furthermore, a plurality of liquid adding holes are provided on the liquid adding ring 705, and a plurality of liquid adding holes are provided on the feed pipe 601. The plurality of liquid adding holes on the liquid adding ring 705 and the plurality of liquid adding holes on the feed pipe 601 overlap respectively. The liquid adding ring 705 injects the early setting agent into the feed pipe 601 through the plurality of liquid adding holes above it and the plurality of liquid adding holes on the feed pipe 601. The position where the early setting agent is added is above the spiral blade shaft 602. The spiral blade shaft 602 can also stir the concrete material in the process of extruding the concrete material downward, so that the concrete material and the early setting agent are fully mixed. The concrete material with the early setting agent added can solidify faster, thereby speeding up the construction progress. The plurality of liquid adding holes can make the early setting agent added more uniformly, thereby promoting the mixing efficiency. The arrangement makes it possible for the liquid adding ring 705 to add the early setting agent to the concrete material through a plurality of liquid adding holes when the concrete material enters the discharge pipe 601, and the concrete material and the early setting agent are fully mixed and then extruded through the stirring of the spiral blade shaft 602, thereby accelerating the solidification speed of the concrete material and avoiding the situation in which the concrete material is stacked to a higher position and the compression resistance is insufficient due to the slow solidification time of the concrete at the bottom, thereby causing structural deformation and collapse. The early setting agent is added to the discharge pipe 601, so as to achieve the effect of adding the early setting agent before the concrete material is extruded, delaying the time of adding the early setting agent, and avoiding the problem that the conventional method of adding the early setting agent in advance will cause the concrete material to solidify in advance in the material box 4, thereby affecting the fluidity of the concrete material.

[0044] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0045] Working principle: the motor on the portal frame 2 can drive the roller group to rotate, so that the portal frame 2 can move forward and backward on the ground rail 1, and the two hydraulic cylinders of the portal frame 2 can drive the mounting seat 3 to move up and down on the portal frame 2. The motor at the bottom of the material box 4 can drive the roller group to rotate, so that the material box 4 can move left and right on the mounting seat 3, so that the material box 4 can be adjusted in six directions of front, back, left, right, up and down. Through the control of the computer host, the material box 4 can move according to the set motion trajectory. There is a feeding port on the material box 4. The operator uses a pipeline to connect the feeding port on the material box 4 with the concrete delivery pump, and the concrete is added to the material box 4 through the pipeline by the concrete delivery pump; after starting the motor 501, the motor 501 drives the reciprocating screw rod 502 to rotate. Since the inner wall of the material box 4 limits the ball slide 503 and the two mounting arms 504, the ball slide 503 and the two mounting arms 504 can only slide up and down, so that when the reciprocating screw rod 502 rotates, the ball slide 503 and the two mounting arms 504 are driven by the cooperation of the reciprocating thread groove and the ball. 4 reciprocates up and down, and the two mounting arms 504 drive the multiple vibration rods 505 to reciprocate up and down. The vibration rods 505 contact the surface of the sawtooth plate 506 during the up and down movement, so that the vibration rods 505 are driven by the sawtooth surface of the sawtooth plate 506 to vibrate. The multiple vibration rods 505 contact the concrete material in the material box 4 during the movement and transmit the vibration to the concrete material, thereby vibrating and compacting the concrete material; through the setting of the vibrating device 5, the multiple vibration rods 505 can also vibrate during the up and down reciprocating movement, and the multiple vibration rods 505 can vibrate and compact the concrete material inside the material box 4 during the vibration, thereby improving the density of the concrete material; through the cooperation of the reciprocating screw rod 502 and the ball carriage 503, the two mounting arms 504 can drive the multiple vibration rods 505 to reciprocate up and down in the material box 4, thereby increasing the contact area between the multiple vibration rods 505 and the concrete material, so that the concrete of different depths in the material box 4 can be vibrated and compacted, thereby improving the vibration and compaction effect.

[0046] The concrete material in the material box 4 falls into the discharge pipe 601 by gravity, and the concrete material in the discharge pipe 601 is discharged through multiple discharge holes on the discharge head 603. The material box 4 keeps moving in this process, so that the discharge head 603 moves with the material box 4, and the concrete material is stacked layer by layer according to the set motion trajectory. The reciprocating screw rod 502 drives the spiral blade shaft 602 to rotate when it rotates. The spiral blades on the spiral blade shaft 602 can squeeze the concrete material in the discharge pipe 601 downward, so that the concrete material is discharged from the discharge head 603 more evenly to avoid blockage. The reciprocating screw rod 502 drives the two scraping bars 605 to rotate through the two mounting rods 604 when it rotates. The two scraping bars 605 are located below the connection between the material box 4 and the discharge pipe 601. The connection between the discharge pipe 601 and the material box 4 is set to a funnel shape, which is convenient for the concrete material in the material box 4 to fall. The two scraping bars 605 are During the rotation, the concrete material attached to the funnel-shaped inner wall of the discharge pipe 601 is continuously scraped to promote the falling of the concrete material, and to prevent part of the concrete material from being attached to the connection between the material box 4 and the discharge pipe 601 for a long time and solidifying, thereby affecting the fluidity of the subsequent concrete material; through the setting of the discharge device 6, the spiral blade shaft 602 can continuously squeeze the concrete material in the discharge pipe 601 downward by rotation, and the concrete material is extruded through the discharge head 603, so that the flow rate and rate of the concrete material extrusion are relatively uniform, thereby improving the work quality; through the setting of the two scraping bars 605, the two scraping bars 605 can continuously scrape off the concrete material attached to the inner wall of the discharge pipe 601 by rotation, and to prevent part of the concrete here from solidifying due to long-term attachment, thereby affecting the passability of the subsequent concrete material in the discharge pipe 601, and finally affecting the overall fluidity of the concrete material.

[0047] The reagent box 701 is filled with an early setting agent. The mounting arm 504 located below the airbag 702 will contact and squeeze the airbag 702 during the upward movement. After being squeezed, the airbag 702 injects air into the reagent box 701 through the air pipe 703. The reagent box 701 uses the positive pressure principle to transport the early setting agent to the liquid adding ring 705 through the liquid pipe 704. The liquid adding ring 705 injects the early setting agent into the discharge pipe 601 through the multiple liquid adding holes above it and the multiple liquid adding holes on the discharge pipe 601. The position where the early setting agent is added is above the spiral blade shaft 602. The spiral blade shaft 602 can also stir the concrete material in the process of extruding the concrete material downward, so that the concrete material and the early setting agent are fully mixed. The concrete material with the early setting agent added can solidify faster, thereby speeding up the construction progress. Due to the arrangement of the feeding device 7, when the concrete material enters the discharge pipe 601, the liquid adding ring 705 adds the early setting agent to the concrete material through a plurality of liquid adding holes, and the concrete material and the early setting agent are fully mixed and then extruded through the stirring of the spiral blade shaft 602, thereby accelerating the solidification speed of the concrete material and avoiding the situation in which the concrete material is stacked to a higher position and the compression resistance is insufficient due to the slow solidification time of the concrete at the bottom, thereby causing structural deformation and collapse. The early setting agent is added to the discharge pipe 601, so as to achieve the effect of adding the early setting agent before the concrete material is extruded, delaying the time of adding the early setting agent, and avoiding the problem that the conventional method of adding the early setting agent in advance causes the concrete material to solidify in advance in the material box 4, thereby affecting the fluidity of the concrete material.
