Description

Technical Field

[0001] The utility model relates to the technical field of deep-sea mining, in particular to a bionic pick for crushing deep-sea ores. Background Art

[0002] Deep-sea metal mineral resources in the ocean deserve our special attention. They are rich in various rare and precious metal elements such as cobalt, manganese, iron, nickel, copper and titanium. As the exploitable metal mineral resources on land, especially on the shallow surface, are gradually exhausted, the deep-buried deposits at the bottom of the ocean provide a better choice for the shortage of land metal supply. Deep-sea ore crushing picks are cutting tools on deep-sea ore mining equipment. Their performance directly affects the production capacity, energy consumption, working stability and service life of other related parts of the mining robot.

[0003] The existing deep-sea ore crushing pick structure design is simple, and its smooth surface structure is in surface contact with the rock, which not only increases the contact area between the pick and the ore, but also aggravates the wear of the pick, resulting in increased energy consumption during mining and reduced service life of the pick. Therefore, reducing the resistance and wear of the pick during operation will greatly improve the mining efficiency and life of the mining robot. Utility Model Content

[0004] The utility model provides a bionic pick for crushing deep-sea ore, aiming to solve the problems of poor drag reduction and wear resistance and low mining efficiency of the existing pick.

[0005] To achieve the above purpose, the technical solution of the utility model is:

[0006] The utility model provides a bionic pick for crushing deep-sea ore, comprising:

[0007] The pick head has a conical structure, and its outer circumference is evenly provided with five rows of No. 1 elliptical protrusions and five rows of No. 2 elliptical protrusions from top to bottom, and the protrusion height of the No. 2 elliptical protrusion is greater than the protrusion height of the No. 1 elliptical protrusion;

[0008] A pick tooth body, wherein the pick tooth head is arranged at the top thereof; the upper part thereof is a truncated cone structure, and the lower part thereof is provided with a pick tooth rod; the outer circumferential surface of the upper truncated cone structure is evenly provided with two rows of No. 3 elliptical protrusions, one row of No. 4 elliptical protrusions, one row of No. 5 elliptical protrusions, one row of No. 6 elliptical protrusions and one row of No. 7 elliptical protrusions from top to bottom, and the protrusion heights of the No. 3 elliptical protrusion, the No. 4 elliptical protrusion, the No. 5 elliptical protrusion, the No. 6 elliptical protrusion and the No. 7 elliptical protrusion are increased in sequence;

[0009] The tooth sleeve is sleeved on the pick tooth rod and embedded and fixed in the tooth seat.

[0010] Furthermore, the protrusion height of the second elliptical protrusion is equal to 1.5 times the protrusion height of the first elliptical protrusion.

[0011] Furthermore, an M-shaped concave surface is provided at the center of the bottom surface of the pick head.

[0012] Furthermore, an M-shaped convex surface is provided at the center of the top of the pick tooth body, which fits with the M-shaped concave surface on the bottom surface of the pick head.

[0013] Furthermore, a retaining groove is provided at the lower part of the pick tooth rod for installing a retaining spring.

[0014] Furthermore, a semicircular groove is provided at the bottom of the truncated cone structure of the pick tooth body.

[0015] Furthermore, a semicircular convex ring is provided on the top of the gear sleeve, and the semicircular convex ring is in contact and fit with the semicircular groove.

[0016] Furthermore, a gear sleeve mounting hole is provided along the axis of the gear seat.

[0017] Furthermore, the gear sleeve is embedded in the gear sleeve mounting hole of the gear seat and can rotate relatively.

[0018] Further, the first elliptical protrusion, the second elliptical protrusion, the third elliptical protrusion, the fourth elliptical protrusion, the fifth elliptical protrusion, the sixth elliptical protrusion and the seventh elliptical protrusion are combined into a prismatic structure.

[0019] The beneficial effects achieved by the utility model are:

[0020] When ordinary picks are used to crush deep-sea ores, the crushed ore particles will continuously rub against the surface of the tooth body, causing greater wear. The utility model utilizes the principle of bionics to combine two non-smooth surface structures, prismatic and convex, and applies them to the surface of deep-sea ore crushing picks. When the pick is crushing ore, the convex surface structure can change the abrasive particles between the pick and the ore from sliding to rolling, thereby reducing wear by changing the movement of the abrasive particles. It also causes the ore particles to change their direction of movement and leave the tooth surface, reducing wear. A plurality of rib-shaped structures composed of a plurality of elliptical protrusions can cause the ore particles to rebound in the rib grooves and collide with subsequent ore particles, thereby reducing their kinetic energy and weakening their impact force. At the same time, the movement state of the ore particles on the pick surface changes, thereby achieving the purpose of reducing drag and wear resistance, and improving crushing efficiency, while also reducing energy consumption.

[0021] The M-shaped concave surface at the bottom of the pick head of the utility model matches with the M-shaped convex surface at the top of the pick tooth body, thereby increasing their contact area and making the pick head more secure when brazing with the pick tooth body;

[0022] The semicircular groove of the pick tooth body of the utility model fits with the semicircular convex ring on the tooth sleeve, increasing their contact area, so that the main force bearing part of the tooth sleeve is on the semicircular convex ring, thereby reducing the deformation of the tooth sleeve and the wear of the pick, and improving the service life of the pick and the mining efficiency;

[0023] The clamping spring of the utility model clamps the tooth sleeve and the tooth body of the pick together on the tooth seat, so when the tooth body of the pick or the tooth sleeve is damaged, it is convenient to replace and repair. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] According to long-term bionics research, the convex structure on the surface of soil organisms and the prismatic structure on the shell surface of marine shellfish have good drag reduction and wear resistance. For this reason, this patent combines the two structures of prismatic and convex shapes and applies them to the surface of deep-sea ore crushing picks to change the contact mode between the surface of the crushing picks and deep-sea ore mud and other materials, thereby improving the drag reduction and wear resistance of the cobalt-rich crust crushing picks and the mining efficiency.
