Description

[0002] In the production and preparation process of plastic inspection wells, the precise transportation and supply of materials are the key links to ensure product quality and production efficiency. As an important component in the construction of urban underground infrastructure, plastic inspection wells are widely used and have strict requirements on performance and quality.

[0003] In the traditional preparation process of plastic inspection wells, the material suction link mostly relies on manual operation or semi-automatic equipment. Manual material suction is not only inefficient and difficult to meet the needs of large-scale production, but also greatly affected by human factors, making it difficult to ensure the accuracy of material delivery, which in turn affects the stability of the quality of plastic inspection well products. Although semi-automatic suction equipment has reduced the intensity of manual labor to a certain extent, there are still certain problems. During the suction process, most of these existing equipment cannot be automatically and accurately adjusted according to the real-time material demand changes in the production process, and often suck too much or too little material. Excessive suction can easily cause material waste and increase production costs, while too little suction can cause production interruptions and reduce production efficiency. Secondly, the internal cleaning and maintenance of existing semi-automatic suction equipment is relatively complicated, which requires a lot of time and manpower costs.

[0013] A material suction method of a fully automatic material suction machine for preparing a plastic inspection well, using the above-mentioned fully automatic material suction machine for preparing a plastic inspection well, comprises the following steps: Step 1: Suction: Start the suction pump to form negative pressure in the suction barrel. The material moves toward the bottom of the suction barrel along the spiral track through the feed pipe under the action of negative pressure and spiral guide vanes. Under the action of centrifugation, the material gathers at the bottom of the suction barrel. Step 2: discharging materials, start the power motor, and adjust the rotation direction of the output end of the power motor so that when the power rotating rod drives the ratchet disc to rotate, the one-way pawl is toggled on one side of the one-way ratchet wheel, so that the one-way ratchet wheel is in a stationary state. The driving rod is driven to rotate by the rotation of the power rotating rod, and the driving plate is toggled by the driving rod to move, so that the stepping driving ring is rotated.

[0015] 2. In the present disclosure, by setting a step-by-step discharge assembly and a feeding power assembly, by adjusting the rotation direction of the output end of the power motor, not only can the rotation of the quantitative discharge rotating rod and the spiral feeding blade be accurately controlled to achieve accurate discharge of materials, but also after the material is loaded, by adjusting the rotation direction of the output end of the power motor, the spiral guide blade and the spiral feeding blade can be rotated at the same time to scrape the material attached to the inner wall of the suction barrel toward the direction of the spiral feeding blade.
