Weighing mechanism of sand adding equipment for petroleum fracturing construction

Abstract

The invention relates to the technical field of petroleum construction, in particular to a weighing mechanism of sand adding equipment for petroleum fracturing construction, which comprises a machine base with a supporting rod at the bottom, a guide channel is leftwards formed in the right side of the machine base, a guide seat is arranged in the guide channel, a driving mechanism for driving the guide seat to move left and right in the guide channel is arranged at the top of the machine base, a crushing frame is arranged at the right end of the guide seat and is a triangular welding frame, the top edge of the crushing frame extends towards the guide channel and is provided with a row of scraping grooves, the front inclined face and the rear inclined face of the crushing frame are each provided with a row of discharging openings, the right end of the crushing frame is provided with an extrusion plate moving left and right along with the right end of the crushing frame, the left end of the extrusion plate is provided with a pressing seat moving along with the extrusion plate, a material channel is formed in the lower left portion of the right end of the machine base. Due to the fact that the device is provided with the crushing frame, the weighing mechanism not only can be suitable for weighing and throwing of sand materials with packaging bags, but also can be suitable for direct weighing and throwing of common sand materials without packaging bags, and is high in universality compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of sand adding equipment for oil fracturing construction, in particular to a weighing mechanism of sand adding equipment for oil fracturing construction. Background technique [0002] With the deepening of domestic natural gas exploration and development, both the total amount of construction and the scale of construction are gradually increasing every year, with an annual growth rate of about 20%. The total amount and scale of large-scale fracturing operations are expanding, and the amount of sand delivered has also increased significantly. The Chinese patent application No. CN202010445833.4 discloses a belt-driven quick-connect weighing mechanism, including a weighing platform and a gate assembly arranged on the weighing platform. The weighing platform includes a platform body and an opening and closing mechanism. mechanism, a groove is set in the center of the platform body, a sand guide groove is opened...

AI Technical Summary

Problems solved by technology

However, this device cannot form an assembly-line feeding operation. When weighing the sand, the discharge port adopts a gate structure. When the sand is put in, an oil cylinder is required to drive its opening and closing action, and most of the sand is packed in bags. , this mechanism lacks a crushing mechanism to crush it, this mechanism can only be adapted to the direct feeding of crushed sand, and the general effect is poor
