Description

Technical Field

[0001] This utility model relates to the field of circular large excavator bucket technology, and more specifically, to a circular large excavator bucket for gold extraction. Background Technology

[0002] In gold mining equipment, large circular buckets are mainly used for scooping up gold-bearing sand over large areas. The grid or adjustable screen at the bottom of the bucket can simultaneously filter out larger stones, reducing unnecessary load. This is the main difference between it and ordinary excavator buckets. However, in actual use, two major problems exist:

[0003] Firstly, after long-term use, the grating or screen is easily clogged by particles such as stones, resulting in poor separation of mud and sand.

[0004] Secondly, the teeth of the circular large excavator bucket are fixedly connected and cannot be rotated or adjusted. When digging mud and sand, they will wear out abnormally severely once they directly impact solid objects, making the teeth very easy to damage. Therefore, this application proposes a circular large excavator bucket for gold extraction, aiming to effectively solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a large circular digging bucket for gold extraction, in order to solve the problems mentioned in the background art above:

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A large circular bucket for gold mining includes a bucket barrel, an mounting platform fixedly connected to the upper part of the bucket barrel, a toothed sleeve rotatably connected to the mounting platform, a plurality of bucket teeth fixedly connected to the upper part of the toothed sleeve, a first ball bearing rotatably connected to the upper part of the mounting platform, a positioning body fixedly connected to the lower part of the toothed sleeve, and a second ball bearing rotatably connected to the positioning body.

[0008] An inner cylinder is movably installed at the lower part of the bucket, and a screen is fixedly connected to the bottom surface of the inner cylinder.

[0009] By adopting the above technical solution, the rotation of the tooth sleeve allows the bucket teeth to rotate and shift the angle and change the position of the bucket teeth when they impact solid objects, thus avoiding localized damage and rapid wear caused by the bucket teeth impacting objects perpendicularly.

[0010] Meanwhile, the inner cylinder can move up and down. During the hopper's rotation, the inner cylinder shakes up and down, making it easy for solid objects such as stones on the screen to fall off due to vibration, thus making the screen easier to clear.

[0011] Preferably, an inner ring is fixedly connected to the inner side of the toothed sleeve, an outer ring is fixedly connected to the outer side of the toothed sleeve, and the mounting platform is located between the inner ring and the outer ring.

[0012] By adopting the above technical solution, the gear sleeve is confined to the position of the mounting platform.

[0013] Preferably, the mounting platform has several No. 1 positioning holes, the No. 1 ball is movably installed in the No. 1 positioning hole, and the gear sleeve is rotatably connected to the mounting platform through the No. 1 ball.

[0014] By adopting the above technical solution, the No. 1 ball is rotatably connected to the top position at the inner side of the gear sleeve.

[0015] Preferably, the outer ring has a mounting groove and a fixing screw hole, and the fixing screw hole is located in the area where the mounting groove is located.

[0016] Preferably, the positioning body is located in the mounting groove, and a fixing bolt is movably installed on the positioning body. The fixing bolt passes through the positioning body and is threadedly connected to the fixing bolt hole. A second positioning hole is opened on the positioning body, and a second ball bearing is movably installed in the second positioning hole. The positioning body is rotatably connected to the mounting platform through the second ball bearing.

[0017] By adopting the above technical solution, the positioning body restricts the tooth sleeve from moving upward.

[0018] Preferably, the bucket has several movable openings, a connecting rod is fixedly connected to the outer end of the inner cylinder, the connecting rod is movably installed in the movable opening, and a baffle plate is fixedly connected to the outer end of the connecting rod, the baffle plate is movably installed on the outer side of the bucket.

[0019] By adopting the above technical solution, the inner cylinder moves up and down inside the bucket, which facilitates vibration, making it easier for the screen to remove stones and other objects from the mesh and clear the blockage.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1) The tooth sleeve of this large circular bucket can drive the bucket teeth to rotate, so that when the bucket teeth are digging mud and sand, when the bucket teeth come into contact with solid hard objects, they can rotate autonomously after being subjected to force, changing the angle and position of the bucket teeth, avoiding the bucket teeth from impacting the hard objects perpendicularly, which would cause local breakage or rapid damage.

[0022] 2) This large circular bucket can be flipped up and down, causing the inner cylinder to shake and vibrate, making it easier for stones and other objects on the screen mesh to fall off and making the screen easier to clear. Attached Figure Description

[0031] Example 1, please refer to Figures 1 to 5 A circular large excavator bucket for gold extraction includes a bucket cylinder 1. A mounting platform 9 is fixedly connected to the upper part of the bucket cylinder 1. A toothed sleeve 2 is rotatably connected to the mounting platform 9. Several bucket teeth 4 are fixedly connected to the upper part of the toothed sleeve 2, so that the toothed sleeve 2 can easily drive the bucket teeth 4 to rotate and change their position and angle. A first ball bearing 11 is rotatably connected to the upper part of the mounting platform 9. A positioning body 12 is fixedly connected to the lower part of the toothed sleeve 2. A second ball bearing 15 is rotatably connected to the positioning body 12. The first ball bearing 11 and the second ball bearing 15 clamp the mounting platform 9 in the middle position.

[0032] The inner ring 5 is fixedly connected to the inner side of the toothed sleeve 2, and the outer ring 6 is fixedly connected to the outer side of the toothed sleeve 2. The mounting platform 9 is located between the inner ring 5 and the outer ring 6, so that the toothed sleeve 2 can be easily fixed on the mounting platform 9 and will not move laterally or fall off.

[0033] The mounting platform 9 has several No. 1 positioning holes 10. The No. 1 ball 11 is movably installed in the No. 1 positioning hole 10. The gear sleeve 2 is rotatably connected to the mounting platform 9 through the No. 1 ball 11. The No. 1 ball 11 is located inside the gear sleeve 2.

[0034] The outer ring 6 has an installation groove 7 and a fixing screw hole 8. The fixing screw hole 8 is located in the area where the installation groove 7 is located, and the fixing screw hole 8 and the installation groove 7 are interconnected.

[0035] The positioning body 12 is located in the mounting groove 7. The positioning body 12 is embedded in the mounting groove 7, so that the positioning body 12 cannot move laterally. The positioning body 12 is movably mounted with a fixing bolt 13. The fixing bolt 13 passes through the positioning body 12 and is threadedly connected to the fixing screw hole 8. The fixing bolt 13 fixes the positioning body 12 on the outer ring 6. The positioning body 12 has a second positioning hole 14. A second ball bearing 15 is movably mounted in the second positioning hole 14. The positioning body 12 is rotatably connected to the mounting platform 9 through the second ball bearing 15, so that the positioning body 12 rotates synchronously with the gear sleeve 2.

[0036] The steps of using this utility model are as follows: When the large circular bucket is digging mud and sand, when the bucket teeth 4 directly collide with hard objects such as stones in the mud, the tooth sleeve 2 can rotate on the mounting platform 9 through the first ball bearing 11. When the tooth sleeve 2 rotates, the outer ring 6 drives the positioning body 12 to move synchronously. The second ball bearing 15 on the positioning body 12 rotates at the bottom of the mounting platform 9. When the bucket teeth 4 directly impacts the hard object, if the impact force is too large, the tooth sleeve 2 will rotate under the force, thereby deflecting the angle and position of the bucket teeth 4, avoiding the bucket teeth 4 from vertically colliding with the hard object, and avoiding local breakage and rapid wear of the bucket teeth 4.

[0037] Example 2, please refer to Figure 1 , Figure 3 , Figure 6 and Figure 7 The difference from embodiment 1 is that an inner cylinder 3 is movably installed at the lower part of the bucket 1, and the inner cylinder 3 is slidably connected inside the bucket 1. A screen 17 is fixedly connected to the bottom surface of the inner cylinder 3, and the inner cylinder 3 drives the screen 17 to move synchronously. Several movable openings 16 are opened on the bucket 1. A connecting rod 18 is fixedly connected to the outer end of the inner cylinder 3, and the connecting rod 18 is movably installed in the movable openings 16. A baffle plate 19 is fixedly connected to the outer end of the connecting rod 18, and the baffle plate 19 is movably installed on the outer side of the bucket 1. The inner cylinder 3 and the baffle plate 19 are located on the inner and outer sides of the toothed sleeve 2, respectively.

[0038] The steps of using this utility model are as follows: When the bucket is digging mud and sand, the bucket 1 is flipped up and down, so that the inner cylinder 3 moves up and down inside the bucket 1. The connecting rod 18 moves up and down synchronously inside the movable opening 16. The baffle plate 19 is driven by the connecting rod 18 to move synchronously. When the inner cylinder 3 moves up and down, the baffle plate 19 blocks the movable opening 16. As the inner cylinder 3 moves up and down, vibration is generated, so that the screen 17 on the inner cylinder 3 can shake off hard objects such as stones from the mesh through vibration, thereby clearing the screen 17.
