Fully automatic multifunctional pumping machine

Abstract

The invention discloses a full-automatic multi-functional pumping machine. The full-automatic multi-functional pumping machine comprises a pumping machine main body; a hopper is arranged on the pumping machine main body; a pumping device corresponding to the hopper is arranged inside the pumping machine main body; the pumping device is composed of two concrete conveying cylinders and pumping connectors, wherein the concrete conveying cylinders are arranged in parallel and are capable of realizing continuous pumping, and each pumping connector is arranged at the tail end of the corresponding concrete conveying cylinder; each concrete conveying cylinder is provided with a sealing cover plate; each sealing switch plate is arranged between the corresponding concrete conveying cylinder and the corresponding connector; each switch oil cylinder is arranged between the corresponding sealing cover plate and the corresponding sealing switch plate. According to the full-automatic multi-functional pumping machine disclosed by the invention, each sealing switch plate and the corresponding sealing cover plate are synchronously linked with each other by the corresponding switch oil cylinder between the corresponding sealing switch plate and the corresponding sealing cover plate; the two sides of each switch oil cylinder are uniformly stressed, so eccentric stress of a single side is avoided, the problems of eccentric abrasion and insufficient driving power are prevented, and the service life of a product is prolonged.

Description

technical field [0001] The invention belongs to the technical field of pumping machinery, and in particular relates to a fully automatic multifunctional pumping machine. Background technique [0002] In recent years, with the continuous and rapid development of the economy, the construction machinery industry has made great progress. At present, my country has become the world's largest production and sales country of construction machinery. . [0003] Among construction machinery, the development of pumping machinery is particularly prominent. Among them, concrete pumping machinery is a machine that uses pressure to transport concrete along pipelines. Due to its complicated structure and principle, existing concrete pumping machinery cannot be miniaturized. They are all relatively large, and cannot adapt to the secondary pouring of floor concrete, nor can they adapt to operations such as indoor spraying and roughening. In order to solve the above technical problems, the ap...

Problems solved by technology

[0003] Among construction machinery, the development of pumping machinery is particularly prominent. Among them, concrete pumping machinery is a machine that uses pressure to transport concrete along pipelines. Due to its complicated structure and principle, existing concrete pumping machinery cannot be miniaturized. Both are relatively large, unable to adapt to the secondary pouring of floor concrete, and also unable to adapt to operations such as indoor spraying and roughening

In order to solve the above technical problems, the applicant applied for a multifunctional self-falling pumping machine on May 8, 2015, which can meet the requirements of a miniaturized pumping machine, and the result is a simpler principle, but it also has the following advantages: One disadvantage: 1. The sealed switch plate and the sealed cover plate are synchronously linked by the switch cylinder. During the linkage process, the switch cylinder is only eccentrically stressed on one side, which is prone to eccentric wear and insufficient driving power. Long-term use wears seriously and reduces the product life. ;2. The sealing switch plate and the sealing cover are synchronously linked. While sealing the blanking opening of the concrete delivery cylinder, the corresponding concrete delivery cylinder and the pumping connector are connected, and other concrete delivery cylinders and the pumping connector are cut off at the same time. However, during the movement of the seal switch plate and the seal cover plate, when the seal cover partially covers the blanking opening of one of the concrete delivery cylinders, the seal switch plate may communicate with the two feed pipes at the same time. Concrete backflow may therefore occur
