[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 9 This utility model provides a low-plasticity concrete anti-adhesion conveyor belt, which includes:

[0030] A frame 100 and a main support frame 200 mounted on the frame 100. A secondary support frame 300 is slidably installed inside the main support frame 200. A conveyor belt 400 is mounted on the main support frame 200 and the secondary support frame 300. A power motor 210 for driving the conveyor belt 400 to rotate is mounted on the main support frame 200.

[0031] A scraper mechanism 500 is used to scrape away concrete adhering to the conveyor belt 400. The scraper mechanism 500 is installed below the front end of the secondary support frame 300 and includes a support pipe 510. The support pipe 510 is fixedly installed at the front end of the secondary support frame 300, and a sleeve 520 is sleeved on the support pipe 510. A fixing plate 530 is fixedly installed on the sleeve 520. The fixing plate 530 has an installation groove. A scraper 540 is slidably installed in the installation groove. A plurality of connecting springs 541 are evenly installed at the bottom end of the scraper 540. The ends of the plurality of connecting springs 541 facing away from the scraper 540 are fixedly connected to the bottom of the installation groove. An adjusting component 550 for adjusting the angle of the scraper 540 is installed on the support pipe 510.

[0032] The adjusting component 550 includes a worm gear 551 sleeved on one end of the sleeve 520, and an adjusting worm 552 rotatably mounted on one side of the secondary support frame 300, wherein the adjusting worm 552 meshes with the worm gear 551.

[0033] It should be noted that during use, when conveying low-plasticity concrete using the conveyor belt 400, the worm wheel 551 is driven to rotate by turning the adjusting worm 552. This causes the worm wheel 551 to drive the sleeve 520 to rotate around the support pipe 510, thereby adjusting the angle of the scraper 540 installed on the sleeve 520. Under the drive of the connecting spring 541, the scraper 540 is always attached to the bottom of the conveyor belt 400 at the front end of the secondary support frame 300, scraping away the concrete adhering to the conveyor belt 400.

[0034] It is worth noting that: the conveyor belt 400 is installed on the main support frame 200 and the auxiliary support frame 300. Multiple sets of auxiliary support rollers 101 are installed at the top of both the main support frame 200 and the auxiliary support frame 300. To enable telescopic conveying, a drive roller 102 for driving the conveyor belt 400 is installed at the end of the main support frame 200 near the frame 100. The drive roller 102 is connected to the power motor 210 via a reducer for drive. A steering roller 105 is installed at the other end of the main support frame 200. A tension roller 103 is provided at the front end of the auxiliary support frame 300. To directly convey the scraped concrete during scraping, the scraping mechanism 500 is set... Between the auxiliary support roller 101 and the tension roller 103 at the front end of the secondary support frame 300, and at the rear end of the secondary support frame 300, there is a second steering roller 104. The conveyor belt 400 first passes through the drive roller 102, then is laid sequentially on the top auxiliary support roller 101, then passes through the tension roller 103, then through the second steering roller 104 and the first steering roller 105, and finally wraps back to the drive roller 102. In this way, when the secondary support frame 300 slides along the main support frame 200, the length of the conveyor belt 400 laid on the auxiliary support roller 101 increases, but the distance between the second steering roller 104 and the first steering roller 105 on the secondary support frame 300 decreases synchronously, thereby realizing the synchronous extension and retraction of the conveyor belt 400.

[0035] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 3 One end of the main support frame 200 is hinged to the frame 100. A hydraulic cylinder 110 is symmetrically installed on the front side of the frame 100. One end of the hydraulic cylinder 110 is hinged to the frame 100, and the other end of the hydraulic cylinder 110 is hinged to the middle of the main support frame 200. A rack plate 220 is symmetrically installed on both sides of the main support frame 200. A stepper motor 310 is symmetrically installed at the end of the auxiliary support frame 300. A gear that meshes with the rack plate 220 is fixedly sleeved on the output shaft of the stepper motor 310.

[0036] It should be noted that the main support frame 200 can be extended and retracted by the hydraulic cylinder 110, which can adjust the swing angle of the main support frame 200, making it easier to adjust the conveying angle and achieve better docking. When it is necessary to adjust the length of the conveyor belt, the stepper motor 310 is started. The stepper motor 310 meshes with the rack plate 220 through the gear, thereby driving the secondary support frame 300 to slide along the main support frame 200, thereby adjusting the conveying distance.

[0037] Furthermore, in order for the secondary support frame 300 to slide stably along the main support frame 200, upper limit plates are installed on both sides of the main support frame 200 above the secondary support frame 300, and guide wheel frames for supporting the secondary support frame 300 are installed on both sides of the main support frame 200 above the secondary support frame 300, so as to facilitate the extension and retraction of the secondary support frame 300.

[0038] In the embodiments of this utility model, please refer to Figures 1 to 9 The sub-support frame 300 has a sliding groove 301 at its front end. The sliding groove 301 is vertically arranged, and a pressure plate 560 is slidably installed in the sliding groove 301. Insert rods 561 are symmetrically installed at the top of the pressure plate 560. The insert rods 561 are inserted into the through holes at the front end of the sub-support frame 300, and a compression spring 562 is sleeved on the insert rods 561.

[0039] It should be noted that, in order for the top plate 560 to press the conveyor belt 400 onto the scraper plate 540, the chute 301 is set above the scraper plate 540 and above the belt at that location. Thus, under the drive of the compression spring 562, the top plate 560 is driven to press and fix itself onto the non-conveying surface of the conveyor belt 400, thereby pressing the conveying end face of the conveyor belt 400 onto the scraper plate 540, thereby improving the scraping efficiency of the scraper plate 540.

[0040] In the embodiments of this utility model, please refer to Figures 1 to 9 An air pipe 600 is installed at the front end of the secondary support frame 300 on one side of the support pipe 510. The air pipe 600 has a plurality of air holes 601 evenly opened on the side facing the conveyor belt 400. A sealing pipe 610 is rotatably installed on the air pipe 600. The sealing pipe 610 has ventilation slots 602. One end of the air pipe 600 is connected to an air pump 620. A servo motor 630 for driving the sealing pipe 610 to rotate is installed on one side of the secondary support frame 300.

[0041] The other end of the trachea 600 is fixedly installed with a sealing end cap 640. A return spring 650 is fixedly installed on the end of the sealing end cap 640 facing the trachea 600. A sealing piston 660 is fixedly installed on the end of the return spring 650 away from the sealing end cap 640. The outer side wall of the sealing piston 660 slides in conjunction with the inner side wall of the trachea 600.

[0042] It should be noted that when scraping concrete with the scraper 540, the air pump 620 and the servo motor 630 are started simultaneously. The air pump 620 continuously fills the air pipe 600 with gas. When filling, the air pump squeezes the sealing piston 660 and compresses the return spring 650. When the servo motor 630 drives the sealing pipe 610 to rotate via the pulley drive, when the ventilation groove 602 of the sealing pipe 610 rotates to align with the air hole 601, the gas in the air pipe 600 rushes from the air hole 601 to the conveyor belt 400 above, thereby assisting in scraping concrete and reducing the adhesion rate of the belt.

[0043] It should also be noted that: in order to reduce the interference of concrete on the rotation of the servo motor 630 driving the sealing pipe 610, a protective cover is installed on the rotation transmission part, which is not shown in the figure. The protective cover is used to synchronously cover the adjusting part 550 for easy adjustment later.

[0044] A multi-directional moving conveyor device, utilizing the aforementioned low-plasticity concrete anti-adhesion conveyor belt, further includes: a frame 700 fixedly installed at the bottom of the frame 100, with bridges 710 hinged to both ends of the frame 700; a rotating shaft 711 rotatably mounted on the bridges 710; wheels 712 fixedly mounted at both ends of the rotating shaft 711; a motor 713 for driving the rotating shaft 711 to move, mounted on the bridges 710; and a hydraulic cylinder 720 mounted on the bridges 710, with one end of the hydraulic cylinder 720... The frame 700 is hinged to the top of the frame 100, and the other end of the hydraulic cylinder 720 is hinged to the bridge 710. The left and right sides of the frame 700 are rotatably mounted with shafts 730. The two ends of the shafts 730 are fixedly mounted with wheels 731. The frame 700 is equipped with a motor 732 that drives the shafts 730 to rotate. The frame 700 is equipped with an electro-hydraulic station 800 for controlling the extension and retraction of hydraulic cylinders 720 and 110. The frame 700 is also equipped with a main control box 900 that controls the operation of the entire mobile conveyor.

[0045] It should be noted that: This mobile conveyor device is based on a low-plasticity concrete anti-adhesion conveyor belt with a frame 700. The frame 700 is connected to a bridge 710 at the front and rear ends. The bridge 710 is equipped with a rotating shaft 711 and a wheel 712. The motor 713 is started by the main control box 900, which can move forward and backward. When it is necessary to adjust the conveying position left and right, the hydraulic cylinder 720 is controlled by the electro-hydraulic station 800 to drive the bridge 710 to flip upward until the wheel 712 flips off the ground and the wheel 731 contacts the ground. Then, the motor 732 is controlled to drive the rotating shaft 730 to rotate the wheel 731, thereby realizing the left and right movement adjustment position. This facilitates flexible adjustment of the conveying position.

[0046] Furthermore, in order to enable the swing adjustment of the mobile conveyor, the bridge 710 is also integrated with the steering mechanism of an existing automobile, which facilitates the steering of the conveyor.

[0047] In this embodiment, the electro-hydraulic station 800 and the main control box 900 are also connected to a remote control via cable or wireless communication, which facilitates the overall operation using the remote control.

[0048] It should also be noted that the hydraulic cylinders, motors and air pumps in the entire low-plasticity concrete anti-adhesion conveyor belt and multi-directional moving conveyor device can all be the models commonly used in this technical field. The specific models can be selected according to the parameters. Their control and operation principles are all existing technologies, so they will not be described here.

[0049] The working principle of the low-plasticity concrete anti-adhesion conveyor belt and multi-directional moving conveyor device provided by this utility model is as follows:

[0050] In use, when conveying low-plasticity concrete using the conveyor belt 400, the worm gear 551 is driven to rotate by turning the adjusting worm 552. This worm gear 551 then drives the sleeve 520 to rotate around the support pipe 510, thereby adjusting the angle of the scraper 540 installed on the sleeve 520. Driven by the connecting spring 541, the scraper 540 remains attached to the bottom of the conveyor belt 400 at the front end of the secondary support frame 300, scraping away the concrete adhering to the conveyor belt 400. Furthermore, to allow the top plate 560 to press the conveyor belt 400 onto the scraper 540, a groove 301 is positioned above the scraper 540 and above the belt at that location. Thus, the top plate 560, driven by the compression spring 562... Under the action, the driving pressure plate 560 is pressed and fixed on the non-conveying surface of the conveyor belt 400, thereby pressing the conveying end face of the conveyor belt 400 at this location onto the scraper plate 540, thereby improving the scraping efficiency of the scraper plate 540; at the same time, when scraping concrete with the scraper plate 540, the air pump 620 and the servo motor 630 are started simultaneously. The air pump 620 continuously fills the air pipe 600 with gas. When filling, it squeezes the sealing piston 660 and compresses the return spring 650. When the servo motor 630 drives the sealing pipe 610 to rotate through the pulley drive, when the ventilation groove 602 of the sealing pipe 610 rotates to align with the air hole 601, the gas in the air pipe 600 rushes from the air hole 601 to the conveyor belt 400 above, thereby assisting in scraping concrete and reducing the adhesion rate of the belt;

[0051] Furthermore, the main support frame 200 can be extended and retracted by the hydraulic cylinder 110, which can adjust the swing angle of the entire main support frame 200, facilitating the adjustment of the conveying angle and allowing for better docking. When it is necessary to adjust the length of the conveyor belt, the stepper motor 310 is started. The stepper motor 310 meshes with the rack plate 220 through gears, thereby driving the auxiliary support frame 300 to slide along the main support frame 200, thereby adjusting the conveying distance. A frame 700 is set at the bottom of the frame 100. The frame 700 is connected to the bridge frame 710 at the front and rear ends. The bridge frame 710 is equipped with a rotating shaft 711 and a wheel 712. The main control box is used for this purpose. The 900 control motor 713 starts and can move forward and backward. When the conveying position needs to be adjusted left and right, the electro-hydraulic station 800 controls the hydraulic cylinder 720 to drive the bridge frame 710 to flip upward until the wheel 712 flips off the ground and the wheel 731 contacts the ground. Then, the control motor 732 drives the shaft 730 to rotate the wheel 731, thereby realizing the left and right movement adjustment position. This facilitates flexible adjustment of the conveying position and solves the problems of easy adhesion and limited working range during the conveying of low plasticity concrete. The whole device has the advantages of compact structure, precise adjustment and convenient maintenance.
