A weighing mechanism of sand adding equipment for oil fracturing construction

Abstract

The invention relates to the technical field of petroleum construction, and in particular provides a weighing mechanism for sand-adding equipment for petroleum fracturing construction, which includes a machine base with a support rod at the bottom, a guide channel is opened on the right side of the machine base to the left, and the guide channel There is a guide seat inside, and the top of the machine base is provided with a driving mechanism for driving the guide seat to move left and right in the guide channel. The right end of the guide seat is provided with a crushing frame. The crushing frame is a triangular welding frame, and the top edge of the crushing frame faces the guide The channel is extended and a row of scraping grooves is set on it, and a row of discharge openings are respectively set on the front and rear slopes of the crushing frame. The right end of the crushing frame is provided with a squeeze plate that moves left and right, and the left end of the squeeze plate is equipped with a pressure plate that moves with it. Seat, the right end of the machine seat is provided with material channel towards the lower left direction. Because the device is equipped with a crushing frame, it can not only be adapted to the weighing and dropping of sand materials with packaging bags, but also can be adapted to the direct weighing and feeding of general sand materials without packaging bags. Versatile.

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
