Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology, specifically an adjustable-angle concrete unloading chute device. Background Technology

[0002] Concrete unloading is a crucial step in the construction process. Traditional concrete unloading chute devices often have many limitations.

[0003] Most traditional chute devices have a fixed height, making it difficult to adapt to the unloading needs of construction equipment at different heights. During use, chutes with a fixed height cannot smoothly transport concrete to the designated location, leading to inconvenience in unloading and affecting construction progress. Regarding unloading distance, the length of most traditional chutes is not adjustable. When encountering distant unloading points, concrete is prone to spillage, causing material waste, polluting the construction site, increasing cleanup costs, and making it difficult to guarantee unloading accuracy. Furthermore, the tilt angle of traditional chutes is difficult to adjust, making it impossible to flexibly control the flow direction and speed of concrete unloading. In some complex construction scenarios, it is difficult to meet the requirements of construction processes, affecting the quality of concrete pouring. Therefore, those skilled in the art have provided an adjustable-angle concrete unloading chute device to solve the problems mentioned in the background art. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-4 In this embodiment of the invention, an adjustable-angle concrete unloading chute device includes a base 1, a lifting plate 6, a main chute 10, and an auxiliary chute 11. Two guide rails 4 are fixedly connected to the upper end of the base 1, and servo motors 5 are fixedly installed on the upper ends of each guide rail 4. Threaded rods 501 are fixedly connected to the power output ends of the servo motors 5, and the threaded rods 501 are rotatably connected to the guide rails 4. A lifting plate 6 is positioned above the base 1, and sliders 7 are fixedly connected to both sides of the lifting plate 6, with the sliders 7 threadedly connected to the threaded rods 501. The main chute 10 is positioned above the lifting plate 6, and the auxiliary chute 11 is slidably connected to the upper rear end of the main chute 10. A servo cylinder 8 is positioned below the lower rear end of the main chute 10, and the servo cylinder 8 is rotatably connected to the lifting plate 6. The servo cylinder 8 is equipped with a piston rod 9 at its upper end, which is rotatably connected to the main chute 10. The upper end of the main chute 10 is provided with two limiting grooves on the left and right. The auxiliary chute 11 is fixedly connected to the left and right sides with limiting strips 12, which are locked in the limiting grooves. A fixing screw is threadedly connected to one side of the main chute 10, which can fix the limiting strips 12 to the main chute 10. The upper end of the lifting plate 6 is fixedly connected with a connecting seat 14, and the lower end of the main chute 10 is fixedly connected with a connecting block 13, which is rotatably connected to the connecting seat 14. The guide rail 4 is provided with a sliding groove 401 on one side, and the slider 7 is locked in the sliding groove 401. Locking casters 2 are bolted to the four corners of the lower end of the base 1, and the controller 3 is fixedly installed on the upper end of the base 1.

[0022] The working principle of this utility model is as follows: During use, the servo motor 5 is started, which drives the threaded rod 501 to rotate. The sliders 7 on both sides of the lifting plate 6 are threadedly connected to the threaded rod 501. Simultaneously, the sliders 7 are engaged in the groove 401 on one side of the guide rail 4. As the threaded rod 501 rotates, the sliders 7, guided and constrained by the groove 401, move vertically up and down along the threaded rod 501, thereby driving the lifting plate 6 to move synchronously up and down, realizing the adjustment of the height of the entire chute device to adapt to different unloading height requirements. Furthermore, during the actual unloading process, according to the required unloading distance, the auxiliary chute 11 can be slid onto the main chute 10 to a suitable position, and then the fixing screws on one side of the main chute 10 can be tightened. The fixing screws tightly fix the limiting strip 12 to the main chute 10, thereby locking the position of the auxiliary chute 11 and realizing the adjustment of the chute length to meet different unloading distance working scenarios. In addition, when the servo cylinder 8 is started, the servo cylinder 8 will control the piston rod 9 to perform telescopic movement. Since the piston rod 9 is rotatably connected to the main chute 10 and the servo cylinder 8 is rotatably connected to the lifting plate 6, during the telescopic process of the piston rod 9, a force will be applied to the main chute 10, causing the main chute 10 to rotate around its connection point with the lifting plate 6 (i.e., the rotating connection part of the connecting block 13 and the connecting seat 14), thereby realizing the adjustment of the tilt angle of the main chute 10, which facilitates the control of the flow direction and speed of concrete unloading.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
