[0002] Existing stacker crane technology, as an important part of industrial automation and logistics, has undergone many years of development and innovation. It is widely used in material handling, goods distribution in warehouse management, and goods sorting in logistics centers. These stacker crane systems typically integrate advanced motor drive technology, precision transmission devices, and intelligent control systems, enabling efficient, continuous, and automated material transfer.

[0003] Chinese Patent CN118811372A, authorized and published on October 22, 2024, discloses a novel electric material handling device, including a base frame. A transport base is mounted on the upper surface of the base frame, and two planar conveyor belts and an uphill conveyor belt are mounted on the upper surface of the transport base. Both ends of the uphill and planar conveyor belts are equipped with drive rollers for transmission. An anti-fall mechanism includes a driven roller located inside the uphill conveyor belt. The conveying mechanism includes two auxiliary plates and a support mechanism composed of a weighing component and an inner support component. The weighing component includes a weighing box fixedly installed on one side surface of the transport base. The inner support component includes a fixed roller located inside the planar conveyor belt. In the aforementioned application, when transporting building materials such as bagged cement, the uneven surface of the material can easily cause it to shift, leading to slippage as it moves from the planar conveyor belt to the uphill conveyor belt, thus affecting subsequent material transport and stacking processes.

The rear side of the second hydraulic block is fixedly connected to the positioning plate via a fixing plate. The bottom of the second hydraulic block is movably connected to the extrusion plate via a transmission component. The positioning plate and extrusion plate are designed so that when material falls onto the surface of the feeding conveyor belt, the positioning plates on both sides move inward, automatically centering the bagged cement. This causes the rotating plate to rotate inward and the extrusion plate to move downward, ensuring a tight fit between the bottom surface of the bagged cement and the surface of the feeding conveyor belt.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1, please refer to Figures 1-4 A material stacking device for construction, comprising: The mobile base 100 has a conveyor belt frame 200 on its top, which serves as a fixed equipment frame. A feeding conveyor belt 300 is installed inside the front side of the conveyor belt frame 200. An inclined conveyor belt 400 is movably connected inside the conveyor belt frame 200 to move the bagged cement 600 upwards to a designated height. A discharge conveyor belt 500 is movably connected inside the conveyor belt frame 200 to allow the bagged cement 600 to fall into a stacking box 700. The bagged cement 600 is movably connected to the top of the feeding conveyor belt 300. A stacking box 700 is installed behind the discharge conveyor belt 500. A baffle 800 is fixedly connected to the outside of the conveyor belt frame 200 to prevent the bagged cement 600 from falling out of the equipment during transport. An electric telescopic rod 901 is fixedly connected to the outer side of the conveyor belt outer frame 200 via a fixing bracket 902. The fixing bracket 902 is set to fix the electric telescopic rod 901 to the conveyor belt outer frame 200. A positioning plate 903 is fixedly connected to the inner side of the electric telescopic rod 901. A hydraulic block 905 is fixedly connected to the inner side of the conveyor belt outer frame 200. A push block 904 is movably connected to the inner side of the hydraulic block 905. The inner side of the push block 904 is fixedly connected to the outer side of the positioning plate 903. The interior of the hydraulic block 905 is connected to the interior of the hydraulic block 907 via a hose 906. The rear side of the hydraulic block 907 is fixedly connected to the positioning plate 903 via a fixing plate 908. The bottom of the hydraulic block 907 is movably connected to the extrusion plate 914 via a transmission component. The transmission components include a rack 909, a gear 910, a rotating shaft 911, a rotating plate 912, and an electric cylinder 913. The bottom of the hydraulic block 907 is movably connected to the rack 909. The rotating shaft 911 is movably connected inside the positioning plate 903. The two ends of the rotating shaft 911 are fixedly connected to the gears 910, which mesh with the rack 909. The outside of the rotating shaft 911 is fixedly connected to the rotating plate 912. The top of the rotating plate 912 is fixedly connected to the electric cylinder 913. The bottom of the electric cylinder 913 is fixedly connected to the pressing plate 914. There are two electric telescopic rods 901, each symmetrically distributed about the center line of the movable base 100; there are two positioning plates 903; there are four push blocks 904, with two push blocks 904 forming a group; there are four hydraulic blocks 905, with two hydraulic blocks 905 forming a group; there are four hoses 906; there are four hydraulic blocks 907; there are four racks 909; there are four gears 910; there are two rotating shafts 911; there are two rotating plates 912; there are two electric cylinders 913; and there are two pressing plates 914. The positioning plate 903 and the extrusion plate 914 are configured so that when the material falls onto the surface of the feeding conveyor belt 300, the positioning plates 903 on both sides move inward, thereby automatically centering the bagged cement 600, causing the rotating plate 912 to rotate inward, and causing the extrusion plate 914 to move downward, so that the bottom surface of the bagged cement 600 fits tightly against the surface of the feeding conveyor belt 300, thereby reducing the slippage between the bagged cement 600 and the feeding conveyor belt 300, thus ensuring the smooth progress of the subsequent climbing and stacking processes.

[0021] When the equipment is started, the electric telescopic rod 901 is activated, causing the positioning plate 903 to move inward under the drive of the electric telescopic rod 901, automatically centering the positions of both sides of the bagged cement 600. At the same time, the push block 904 moves inward with the positioning plate 903, reducing the internal pressure of the hydraulic block 905. The internal pressure of the hydraulic block 905 is then transmitted to the hydraulic block 907 through the hose 906, further reducing the internal pressure of the hydraulic block 907. This causes the rack 909 to move upward, rotating the gear 910 and the rotating shaft 911. The rotating plate 912 then rotates and closes with the rotating shaft 911. At this time, the electric cylinder 913 is activated, causing the extrusion plate 914 to move downward, ensuring that the bottom surface of the bagged cement 600 is tightly fitted with the surface of the feeding conveyor belt 300. This reduces slippage between the bagged cement 600 and the feeding conveyor belt 300, allowing the subsequent climbing and stacking processes to proceed smoothly.

[0022] Example 2, please refer to Figures 1-6Based on Embodiment 1, the dust removal assembly 1000 includes a second flexible hose 1001, a second fixed frame 1002, a first chute 1003, a third hydraulic block 1004, a second pusher block 1005, a slider 1006, a suction port 1007, an exhaust pipe 1008, and a dust collection box 1009. The bottoms of the two first hydraulic blocks 905 are fixedly connected to one end of the second flexible hose 1001 via two-way pipes, and the other end of the second flexible hose 1001 is fixedly connected to the bottom of the third hydraulic block 1004. The second flexible hose 1001 is configured to allow communication between the interior of the first hydraulic block 905 and the interior of the third hydraulic block 1004. The top of the conveyor belt outer frame 200 is fixedly connected to the second fixed frame 1002. The second fixed frame 1002 has a first chute 1003 inside, which allows the slider 1006 to slide in a slidable connection with the second fixed frame 1002. A hydraulic block 3 1004 is fixedly connected to the outside. A push block 2 1005 is movably connected to the inside of the hydraulic block 3 1004. A slider 1006 is fixedly connected to the inside of the push block 2 1005. The left and right sides of the slider 1006 are slidably connected to the fixed frame 2 1002 through the sliding groove 1 1003. A dust suction port 1007 is fixedly connected to the bottom of the slider 1006. The dust suction port 1007 is set so that the dust generated during the falling of the bagged cement 600 and transportation is removed by the dust suction port 1007. The bottom horizontal height of the dust suction port 1007 is higher than the top horizontal height of the bagged cement 600. A dust suction fan is fixedly connected inside the slider 1006. An air outlet pipe 1008 is fixedly connected to the top of the slider 1006. A dust collection box 1009 is fixedly connected to the inside of the air outlet pipe 1008 so that the dust sucked out by the equipment is collected. The number of hoses 1001 is two, the number of slides 1003 is two, the number of hydraulic blocks 31004 is two, the number of push blocks 21005 is two, the number of sliders 1006 is two, the number of suction ports 1007 is two, the number of exhaust pipes 1008 is two, and the number of dust collection boxes 1009 is two. The dust removal component 1000 is installed so that the cement fly ash generated when the bagged cement 600 falls onto the surface of the feeding conveyor belt equipment 300 is absorbed and removed by the dust removal component 1000, thereby protecting the safety of the operators and the environment.

[0023] In use, based on Example 1, after the bagged cement 600 completes the centering process, the feeding conveyor belt device 300 is started, and the electric telescopic rod 901 is reset simultaneously, causing the positioning plate 903 to move outward, the push block 1 904 to move outward, and the internal pressure of the hydraulic block 1 905 to increase. The excess pressure inside the hydraulic block 1 905 is transmitted to the hydraulic block 3 1004 through the hose 2 1001, increasing the internal pressure of the hydraulic block 3 1004. This causes the push block 2 1005 to move inward, and the slider 1006 to move inward along the direction of the slide groove 1003. The slider 1006 drives the dust suction port 1007 to move inward, so that the dust suction port 1007 moves back and forth on the surface of the bagged cement 600. This allows the cement fly ash generated when the bagged cement 600 falls onto the surface of the feeding conveyor belt device 300 to be absorbed and removed by the dust suction port 1007, thereby protecting the safety of the operators and protecting the environment.

[0024] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, the stacking buffer assembly 1100 includes a fixed plate 2 1101, a push block 3 1102, a hydraulic block 4 1103, a hose 3 1104, a hydraulic block 5 1105, a fixed plate 3 1106, a push block 4 1107, a rotating block 1108, a rotating plate 2 1109, a slide 2 1110, a buffer plate 1111, and a spring 1112. The fixed plate 2 1101 is fixedly connected to the front side of the positioning plate 903. The push block 3 1102 is fixedly connected to the outer side of the fixed plate 2 1101. The hydraulic block 4 1103 is movably connected to the rear side of the push block 3 1102. The bottom of the hydraulic block 4 1103 is fixedly connected to the interior of the conveyor belt outer frame 200. The bottom of the hydraulic block 4 1103 is fixedly connected to one end of the hose 3 1104, and the other end of the hose 3 1104 is connected to the hydraulic block 5 1105. The top is fixedly connected to a hose 3 1104, which connects the interior of hydraulic block 4 1103 to the interior of hydraulic block 5 1105. The inner side of hydraulic block 5 1105 is fixedly connected to the outer side of the conveyor belt frame 200 via a fixing plate 3 1106. The bottom of hydraulic block 5 1105 is movably connected to a push block 4 1107. The front side of push block 4 1107 is fixedly connected to a rotating block 1108. The outer side of rotating block 1108 is fixedly connected to a rotating plate 2 1109. The surface of rotating plate 2 1109 is provided with a sliding groove 2 1110. Buffer plate 1111 is movably connected to sliding groove 2 1110 via a rotating shaft. A spring 1112 is fixedly connected between buffer plate 1111 and sliding groove 2 1110. The spring 1112 is provided so that buffer plate 1111 can automatically reset. The size of buffer plate 1111 is the same as the size of bagged cement 600. There are two fixed plates 1101, two hydraulic blocks 1103, two hoses 1104, two hydraulic blocks 1105, two fixed plates 1106, two push blocks 1107, two rotating blocks 1108, and two springs 1112. The stacking buffer assembly 1100 is set up so that when the bagged cement 600 falls from the discharge conveyor belt equipment 500, the rotating plate 1109 rotates, so that the bagged cement 600 first falls onto the buffer plate 1111, and then slides from the buffer plate 1111 into the stacking box 700. This reduces the positional displacement of the bagged cement 600 when it falls, reduces the amount of dust when the bagged cement 600 falls, and thus makes the stacking process proceed smoothly.

[0025] In use, based on Embodiment 1 and Embodiment 2, when the positioning plate 903 moves outward, the fixing plate 2 1101 moves outward along with the positioning plate 903, causing the push block 3 1102 to move outward, increasing the internal pressure of the hydraulic block 4 1103. This internal pressure is then transmitted through the hose 3 1104 to the hydraulic block 5 1105, increasing the internal pressure of the hydraulic block 5 1105. This causes the push block 4 1107 to push downward, causing the rotating block 1108 to rotate. The rotating plate 2 1109 then rotates with the rotating block 1108, causing the bagged cement 600 to first fall onto the buffer plate 1111 and then slide off the buffer plate 1111 into the stacking box 700. This reduces positional displacement when the bagged cement 600 falls and reduces dust when it falls, thus ensuring a smooth stacking process.

[0026] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
