Description

Technical Field

[0001] The utility model relates to the technical field of concrete preparation, in particular to a feeding device. Background Art

[0002] A concrete pump, also known as a concrete pump, is a machine that uses pressure to continuously transport concrete along a pipeline. It primarily consists of a hopper, concrete tank, oil cylinder, S-tube swing valve, and delivery pipe.

[0029] a vibration mechanism 11 for generating vibration, wherein the vibration mechanism 11 is height-adjustable by the lifting mechanism 3;

[0030] The unloading mechanism 4 includes an unloading barrel 12, a unloading pipe 19 connected to the bottom of the unloading barrel 12 is fixed, a guide pipe 18 is fixed on the outside of the unloading barrel 12, a metal screen 13 is fixed inside the barrel of the unloading barrel 12, and the outside of the metal screen 13 is in the shape of a conical cover. A cross frame 14 is fixed on the top of the unloading barrel 12, a servo motor 15 is fixed on the outer wall of the cross frame 14, a rotating rod 16 is fixed on the output shaft of the servo motor 15, and a plurality of equally spaced scrapers 17 are fixed on the outer wall of the bottom end of the rotating rod 16. , the aggregate is poured into the discharge barrel 12, and the qualified aggregate passes through the metal screen 13 and falls into the discharge pipe 19, and the unqualified aggregate remains on the metal screen 13. Since the metal screen 13 is in the shape of a cone, the unqualified aggregate rolls outward, and the servo motor 15 rotates the rotating rod 16 axially through the output shaft. The scraper 17 on the rotating rod 16 pushes the unqualified aggregate into the guide pipe 18 and falls out of the guide pipe 18, that is, the unqualified aggregate is discharged from the discharge barrel 12. There is no need to disassemble the metal screen 13 regularly, thereby ensuring the continuity of feeding.

[0031] Specifically, one end of the scraper 17 is fixed along the tangential direction of the rotating rod 16, so that the scraper 17 can push the aggregate outward.

[0032] Specifically, the supporting assembly includes a base plate 1 and four universal wheels 2 with brakes respectively fixed at the four corners of the base plate 1 , and the entire device moves via the universal wheels 2 with brakes.

[0033] Specifically, the lifting mechanism 3 includes a driving assembly, two guide columns 6, a moving frame 10 and a top plate 7. One end of the guide column 6 is fixed to the top of the bottom plate 1, and the moving frame 10 is integrally slidably sleeved on the two guide columns 6. The other end of the guide column 6 is fixed to the top plate 7. The driving assembly includes a traction machine 5 and a transmission wheel 9. Both ends of the transmission wheel 9 are rotatably mounted with fixed plates 8. The fixed plate 8 is fixed to the top plate 7. The traction machine 5 is fixed to the bottom plate 1. The steel rope of the traction machine 5 is passed around the transmission wheel 9 and fixed to the moving frame 10. The traction machine 5 moves the moving frame 10 up and down along the guide column 6 by retracting and releasing the steel rope.

[0034] Specifically, the vibration mechanism 11 includes a vibration motor 21, a buffer assembly and a vibration plate 20. The vibration plate 20 is arranged in the moving frame 10 through the buffer assembly. The vibration plate 20 is fixed to the discharge barrel 12. The buffer assembly includes multiple slide rods 23.

Both ends of the slide rod 23 are sleeved with buffer springs 22, and the two buffer springs 22 are respectively located on the upper and lower sides of the vibration plate 20. The vibration motor 21 causes the vibration plate 20 to vibrate, and the discharge barrel 12 vibrates together with the vibration plate 20, so that the metal screen 13 in the discharge barrel 12 can achieve vibration screening.

[0035] Working principle: Aggregate is poured into the discharge barrel 12, and aggregate of qualified size passes through the metal screen 13 and falls into the discharge pipe 19, while unqualified aggregate remains on the metal screen 13. Since the metal screen 13 is in the shape of a cone, the unqualified aggregate rolls outward, and the servo motor 15 rotates the rotating rod 16 axially through the output shaft. The scraper 17 on the rotating rod 16 pushes the unqualified aggregate into the guide pipe 18 and falls out of the guide pipe 18, that is, the unqualified aggregate is discharged from the discharge barrel 12. There is no need to disassemble the metal screen 13 regularly, so the continuity of feeding is guaranteed.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
