Description

Technical Field

[0001] The utility model relates to the field of concrete processing, in particular to a finished dry-mixed concrete unloading device. Background Art

[0002] Dry-mix concrete is dry-mix mortar, dry-mix cement, etc. Dry-mix means that the materials are mixed in a certain proportion and then transported to the construction site, where water or matching liquid is added in the specified proportion to mix the dry-mix mixture.

[0003] When processing dry-mix concrete, concrete materials with a good proportion are poured into the mixing tank. The stirring blades inside the mixing tank mix the concrete materials evenly. The mixed dry-mix concrete enters the conveying pipe, and the output shaft of the servo motor in the powered state drives the screw rod to rotate. The rotating screw rod transports the dry-mix concrete in the conveying pipe to the output pipe for discharge. When the dry-mix concrete is discharged, it needs to be received and transported by a transport vehicle. However, the conveying pipe is located at a higher position, and the transport vehicle is driven on the ground. When the transport vehicle drives the receiving hopper to the bottom of the conveying pipe, the opening of the output end of the conveying pipe is not aligned with the opening of the receiving hopper, causing the discharged dry-mix concrete to leak out easily.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3 In an embodiment of the utility model, a finished dry-mix concrete unloading device comprises a mixing tank 1, a discharging hopper 2 is fixedly connected to the bottom of the mixing tank 1, a delivery pipe 4 is fixedly connected to the output end of the discharging hopper 2, an output pipe 6 is fixedly connected to the output end of the delivery pipe 4, a positioning mechanism 7 is installed on the outer wall and the output end of the output pipe 6, and the positioning mechanism 7 is used to guide and position the output end of the output pipe 6 and the receiving hopper of the transport vehicle;

[0024] The positioning mechanism 7 includes a driving assembly and a positioning rod assembly;

[0025] The driving assembly is used to drive the positioning rod assembly to operate;

[0026] The positioning rod assembly in the operating state is used to guide and position the output end of the output pipe 6 and the receiving hopper of the transport vehicle.

[0027] In this embodiment: first, the concrete material with a good proportion is poured into the mixing tank 1, and the mixing blades inside the mixing tank 1 mix the concrete material evenly. The mixed dry-mixed concrete then enters the inside of the conveying pipe 4 through the output end of the discharge hopper 2 at the bottom of the mixing tank 1. At this time, the servo motor 3 is powered on and runs. The output shaft of the servo motor 3 in the powered state drives the screw rod 5 to rotate. The rotating screw rod 5 transports the dry-mixed concrete in the conveying pipe 4 to the output pipe 6, so that the dry-mixed concrete is discharged through the output end of the output pipe 6.

[0028] When the dry-mixed concrete is discharged, it needs to be transported by a transport vehicle (it needs to be noted that the opening at the output end of the output pipe 6 is small, and the opening size of the output end of the output pipe 6 is smaller than the opening size of the receiving hopper of the transport vehicle). At this time, the shaft-holding motor 702 is powered on and operated. The output shaft of the shaft-holding motor 702 in the powered state drives the small gear 703 to rotate clockwise. Because the large gear 704 and the small gear 703 are meshed, the small gear 703 in the clockwise rotating state drives the large gear 704 to rotate, and the large gear 704 in the clockwise rotating state drives the turntable 705 to rotate. The turntable 705 drives the multiple arc grooves 706 to rotate, so that the multiple arc grooves 706 squeeze the corresponding positioning rods 707, and the positioning rods 707 in the moving state move in a circle along the trajectory of the arc grooves 706. At the same time, the positioning rods 707 in the moving state move horizontally along the trajectory of the through grooves 709. The multiple positioning rods 707 in the moving state gather inward at the same time, so that the multiple positioning rods 707 gathered inward are clamped on the outer wall of the transport vehicle receiving hopper, and the opening of the output end of the output pipe 6 is aligned with the opening of the transport vehicle receiving hopper, thereby achieving the effect of guiding and positioning the output end of the output pipe 6 and the transport vehicle receiving hopper.

[0029] Please refer to Figure 1 A servo motor 3 is installed on the outer wall of the conveying pipe 4, and a screw rod 5 is rotatably installed on the inner wall of the conveying pipe 4, and the output shaft end of the servo motor 3 is connected to the screw rod 5. The output shaft of the servo motor 3 in the running state is used to drive the screw rod 5 to rotate.

[0030] In this embodiment: the mixed dry-mixed concrete enters the conveying pipe 4 through the output end of the discharge hopper 2 at the bottom of the mixing tank 1. At this time, the servo motor 3 is powered on and the output shaft of the servo motor 3 in the powered state drives the screw rod 5 to rotate. The rotating screw rod 5 transports the dry-mixed concrete in the conveying pipe 4 to the output pipe 6, so that the dry-mixed concrete is discharged through the output end of the output pipe 6.

[0033] In this embodiment: the shaft-holding motor 702 is powered on and operated. The output shaft of the shaft-holding motor 702 in the powered state drives the small gear 703 to rotate clockwise. Because the large gear 704 and the small gear 703 are meshed, the small gear 703 in the clockwise rotating state drives the large gear 704 to rotate, and the large gear 704 in the clockwise rotating state drives the turntable 705 to rotate.

[0034] Please refer to Figure 2 , the positioning rod assembly includes a rotating disk 705, an arc groove 706, a positioning rod 707, a fixing disk 708, and a through groove 709;

[0035] The turntable 705 is rotatably connected to the outer wall of the output tube 6, and the large gear 704 is fixedly connected to the turntable 705, the arc groove 706 is opened at the top of the turntable 705 and completely penetrates, the positioning rod 707 slides circumferentially inside the arc groove 706, the fixed plate 708 is fixedly connected to the output end of the output tube 6, and the turntable 705 is rotatably connected to the fixed plate 708, the through groove 709 is opened inside the fixed plate 708 and completely penetrates, and the positioning rod 707 slides horizontally inside the through groove 709.

[0036] In this embodiment: the turntable 705 in the clockwise rotation state drives the multiple arc grooves 706 to rotate, so that the multiple arc grooves 706 squeeze the corresponding positioning rods 707, and the positioning rods 707 in the moving state move in a circle along the trajectory of the arc grooves 706, and at the same time, the positioning rods 707 in the moving state move horizontally along the trajectory of the through grooves 709.

[0037] Please refer to Figure 2 The large gear 704 and the small gear 703 are meshed with each other, the rotating small gear 703 is used to drive the large gear 704 to rotate, and the rotating large gear 704 is used to drive the turntable 705 to rotate.

[0038] In this embodiment, since the large gear 704 and the small gear 703 are meshed, the small gear 703 rotating clockwise drives the large gear 704 to rotate, and the large gear 704 rotating clockwise drives the turntable 705 to rotate.

[0039] Please refer to Figure 2 The rotating turntable 705 is used to drive the multiple positioning rods 707 to move synchronously, and the multiple positioning rods 707 in the synchronous moving state are used to clamp the outer wall of the transport vehicle receiving hopper.

[0040] In this embodiment: multiple positioning rods 707 in a moving state are gathered inward at the same time, so that the multiple positioning rods 707 gathered inward are clamped on the outer wall of the transport vehicle receiving hopper, and the opening of the output end of the output pipe 6 is aligned with the opening of the transport vehicle receiving hopper.
