Description

Technical Field

[0001] The invention relates to the technical field of bulk cargo transportation equipment, and in particular to a two-flap leak-proof grab bucket. Background Art

[0002] In the early years, the company's bulk cargo operations were mainly bulk ore. Since most bulk ore particles are large, spillage during operations is not serious. After the operation, it is only necessary to collect the remaining goods on site and load them onto trucks, and the cleanup work is relatively simple. However, in recent years, with the increase in the company's bulk cargo operations with smaller particles such as bulk fertilizers and bulk sugar, higher requirements have been placed on the quality of bulk cargo operations.

[0003] At present, the company's existing various types of grab buckets used for bulk mining operations have been in use for a long time, resulting in widespread leakage when used for such small-particle bulk operations. In addition, due to the nature of the cargo, it needs to be waterproof and impurity-proof, and the cargo owners' requirements for loading and unloading quality are much higher than those for bulk mining. The handling of leaked cargo during operations is rather cumbersome, which affects production efficiency and increases the labor intensity of operators.

[0004] In view of the above situation, some existing two-piece grabs are modified to solve the leakage problem in special bulk cargo operations while controlling costs. Summary of the invention

[0005] The purpose of the present invention is to provide a two-piece leak-proof grab bucket which can solve the current leakage problem in special bulk cargo operations.

[0006] To this end, the technical solution of the present invention is as follows:

[0007] A two-flap leakproof grab bucket comprises a first bucket flap and a second bucket flap, two outer sealing racks are symmetrically arranged on the inner walls on the left and right sides of the opening end of the first bucket flap, and a sealing plate is arranged on the bucket mouth plate at the lower side of the opening end of the first bucket flap; two inner sealing racks are symmetrically arranged on the inner walls on the left and right sides of the opening end of the second bucket flap; wherein,

[0008] Each outer sealing rack is arranged in a manner that its axial direction is parallel to the corresponding side end surface of the opening end, and is partially located on the outer side of the first bucket petal; the outer sealing rack is composed of an inverted L-shaped fixing plate and a plurality of first T-shaped teeth; a tooth groove is formed between the inverted L-shaped fixing plate and the inner wall of the bucket petal, and a plurality of first T-shaped teeth are arranged in the tooth groove in a horizontal manner at equal intervals;

[0009] The sealing plate is arranged in a manner that its axial direction is parallel to the bottom side end surface of the first bucket petal opening end and is partially fixed on the inner wall of the bucket mouth plate, and its two ends are respectively fixed on the left and right inner walls of the first bucket petal opening end, and its upper plate surface is connected and fixed to the bottom ends of the two inverted L-shaped fixing plates as a whole;

[0010] Each inner sealing rack is arranged in a manner that its axial direction is parallel to the corresponding side end surface of the opening end, and is partially located on the outer side of the second bucket valve; the inner sealing rack is composed of a plurality of second T-shaped teeth, which are arranged horizontally and evenly spaced on the inner wall of the second bucket valve port side; the plurality of second T-shaped teeth and the plurality of first T-shaped teeth are staggered.

[0011] Furthermore, the vertical rod of each first T-shaped tooth is perpendicular to the long plate of the inverted L-shaped fixed plate and fixed on the surface of the long plate, and the cross rods of each first T-shaped tooth are parallel to each other; the vertical rod of each second T-shaped tooth is perpendicular to the inner wall on the side of the second bucket port and fixed on the inner wall, and the cross rods of each second T-shaped tooth are parallel to each other.

[0012] Furthermore, for the first T-shaped tooth 3b and the second T-shaped tooth 4a in adjacent positions, the spacing between the two vertical rods is 35 mm, the spacing between the two horizontal rods is 40 mm, and the spacing between the horizontal rod and the inner side surface of the inverted L-shaped plate or the horizontal rod and the inner wall of the bucket is 15 mm.

[0013] Furthermore, two long reinforcing ribs and one short reinforcing rib are spaced apart on the inner wall surfaces of the first bucket lobe and the second bucket lobe; the short reinforcing rib is located between the two long reinforcing ribs, and the distance between the short reinforcing rib is consistent with that between the two long reinforcing ribs.

[0014] Furthermore, in the first bucket lobe, the long reinforcing rib plate is an arc-shaped plate, and its length is sufficient to pass through the inner wall of the top of the bucket lobe to the outer edge of the sealing plate; the short reinforcing rib plate is a flat plate, and its length is sufficient to pass through the inner wall of the lower side of the bucket lobe to the outer edge of the sealing plate; in the second bucket lobe, the long reinforcing rib plate is an arc-shaped plate, and its length is sufficient to pass through the inner wall of the top of the bucket lobe to the inner edge of the bucket mouth plate; the short reinforcing rib plate is a flat plate, and its length is sufficient to pass through the inner wall of the lower side of the bucket lobe to the inner edge of the bucket mouth plate.

[0015] Compared with the existing technology, the two-petal leak-proof grab bucket is improved on the existing two-petal grab bucket by adding outer sealing racks, inner sealing racks and sealing plates that can cooperate with each other to achieve the sealing of the gaps that exist when the existing two-petal grab buckets are combined. It effectively solves the problem that small particle cargo is prone to leakage in special bulk cargo operations, and plays a certain role in waterproofing and preventing impurities. At the same time, it avoids the subsequent processing difficulties of leaked cargo, improves production efficiency and reduces the labor intensity of operators. BRIEF DESCRIPTION OF THE DRAWINGS
