Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a novel concrete pump truck feeding port device. Background Technology

[0002] Concrete is one of the most common building materials. It is mainly made of cement as a binder and sand and stone as aggregates, and is mixed with water. It is widely used in civil engineering. In the process of using concrete, concrete pump trucks are a very common type of machinery that uses pressure to continuously transport concrete along pipelines to designated locations.

[0003] A search revealed Chinese patent CN119572015A, which discloses a concrete conveying pump device for civil engineering with an automatic cleaning function. The device includes a pump box and a support frame. The pump box is fixedly mounted on the top of the support frame, and a radiator is fixedly mounted on the top of the pump box. The pump box has ventilation holes on its front side. This invention utilizes a second motor. When the rotating wheel rotates, the impact head abuts against the inner wall of the vibration trough, causing the impact head to retract into the telescopic groove. As the rotating wheel continues to rotate, two other sets of telescopic grooves enter the vibration trough. The impact head is then reset by the elastic potential energy of the compression spring, achieving vibration operation. Compared to traditional devices, this device can simultaneously stir the concrete inside the hopper and vibrate the baffle plate, preventing concrete-laden stones from accumulating and solidifying on the baffle plate, thus reducing the cleaning burden on workers.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] When the aforementioned patents are used, the vibration of the connecting pipe is caused by the power of the concrete conveying process and the motor on the hopper, which can easily lead to the detachment of the discharge pipe and the connecting pipe, affecting the concrete conveying process. In addition, the gap of the baffle plate is fixed and the screening particle size cannot be adjusted according to the needs, resulting in poor functionality and certain limitations.

It also includes an anti-fall-off component 5 and a filter component 6, which can speed up the construction efficiency of the device while ensuring construction safety.

[0035] The truck bed 3 is located at the front end of the frame 1. A discharge pipe 302 is fixedly connected to one side of the truck bed 3, and a conveying pipe 4 is fixedly connected to one end of the discharge pipe 302.

The transverse damping rods 503 and the first buffer springs 509 provide longitudinal shock absorption and buffering for the half-rings 506 and the conveying pipe 4, thereby effectively mitigating the vibration of the conveying pipe 4.

[0040] As a further embodiment of this utility model, a vertical damping rod 505 is fixedly installed on the surface of the movable block 504. The output shaft of the vertical damping rod 505 is fixedly connected to the outside of the half-ring 506.

[0042] Furthermore, a cross plate 603 is fitted around the outside of each mounting shaft 602. A protective shell 604 is fixedly installed on one side of the top of the second mounting frame 601. A rack 605 is movably connected inside the protective shell 604. One end of the mounting shaft 602 extends into the inside of the protective shell 604 and a gear 606 is fixedly installed thereon. The gear 606 meshes with the rack 605. A drive motor 607 is fixedly installed on the inside of the protective shell 604.

A slider 609 is threaded around the outside of the threaded rod 608. The slider 609 is fixedly connected to the rack 605. By using the support arms of different lengths of the cross plate 603, screen holes of different diameters can be constructed. The particle size of the concrete can be adjusted according to different needs, thus improving the practicality of the device.

[0043] The specific working method is as follows: Concrete is placed into the truck bed 3, and the pump in the truck body 2 is started. At the same time, the discharge pipe 302 of the truck bed 3 is connected to the concrete conveying pipe 4. The pump is started, and under the pressure provided by the pump, the concrete in the truck bed 3 is conveyed to the designated position through the conveying pipe 4. When the conveying pipe 4 vibrates, the longitudinal vibration of the conveying pipe 4 is reduced by the transverse damping rod 503 and the first buffer spring 509, and the vertical vibration of the conveying pipe 4 is reduced by the vertical damping rod 505 and the second buffer spring 510, thereby achieving shock absorption and buffering of the conveying pipe 4. The drive motor 607 is started, and the output shaft of the drive motor 607 drives the threaded rod 608 to rotate. The threaded rod 608 drives the rack 605 to move linearly in the longitudinal direction through the slider 609. The rack 605 drives the mounting shaft 602 and the cross plate 603 to rotate through the gear 606. Thus, the support arms of the cross plate 603 of different lengths are used to construct screen holes of different diameters, so as to adjust the screening particle size of the concrete according to different needs.
