Description

Technical Field

[0001] The present invention relates to the technical field of loading and unloading equipment, and particularly relates to a constant-flow crushing type bucket-wheel excavating device. Background Art

[0002] The bucket-wheel excavating device has been gradually developed on the basis of the chain-bucket excavating device, the single-bucket excavating device and other mining equipment. It is an ideal multi-bucket excavating device among continuous operation equipment and is also one of the largest complete sets of excavating equipment in the world. The bucket-wheel excavating device has many advantages such as continuous operation, large production capacity, high efficiency, adaptability to complex coal seam selective mining, large transportation gradient, simple operation, convenient maintenance, and easy realization of modern management. It is especially suitable for high-efficiency mining operations in large open-pit mines and is mainly used in open-pit mines for stripping overburden and excavating useful minerals, mostly in coal mines.

[0003] The bucket-wheel excavating device also has problems in the process of taking coal. Affected by factors such as weather lighting and human habits, it is easy to cause inconsistent coal-taking flow rates. Unstable flow rates are likely to increase the number of heavy-load starts and stops of the coal conveyor belt, affecting the service life of the equipment, and are also likely to cause coal spillage and coal blockage. The size of the coal-taking flow rate determines the running time and maintenance cost of rotating equipment such as the belt and idlers. Summary of the Invention

[0040] Operation process: When one end of the moving support shaft 103b slides to the protruding part in the cam-shaped chute 103e, the moving support shaft 103b moves upward, thereby driving the crushing assembly 201 to rotate by a certain angle around the end of the rotating support shaft 103a, making it easier to sprinkle the minerals in the crushing assembly 201 into the fixed flow assembly 102.

[0041] Embodiment 2

[0042] Refer to Figure 11 , the difference between this embodiment and the first embodiment is that the crushing assembly 201 includes a bucket 201a rotatably disposed at the end of the rotating support shaft 103a, a cutting tooth 201b disposed on the bucket 201a, a crushing rod 201c disposed in the bucket 201a, and a power motor 201d disposed inside the crushing rod 201c. Among them, in this embodiment, eight buckets 201a are taken and are evenly disposed around the inner swash plate 101d, and the crushing rods 201c are disposed at the entrances of the buckets 201a according to the size to be crushed.

[0043] The remaining structures are the same as those in Embodiment 1

[0044] Operation process: When it is necessary to mine minerals, the bucket 201a rotates clockwise around the inner swash plate 101d. The mined minerals enter the bucket 201a through the crushing rod 201c arranged at the entrance of the bucket 201a, breaking the large pieces of minerals into small pieces, crushing the minerals, simplifying the subsequent processing process of the minerals, and also preventing the large pieces of minerals from being stuck when transported to the constant flow component 102.

[0045] Embodiment 3

[0046] Refer to Figures 9 - 10 , what is different about this embodiment from the above embodiments is that the opening and closing component 202 includes a connecting rod member 202c connected to the bottom of the bucket 201a, a reversing member 202d arranged at the bottom of the bucket 201a, an opening and closing plate 202a arranged at one end of the connecting rod member 202c, and an arc plate 202b connected to the inclined funnel 102a. Among them, in this embodiment, the arc plate 202b is a semi-circle, and the arc plate 202b is arranged outside the reverse flow plate, that is, during the process of the bucket 201a mining minerals and transporting the minerals upward.

[0047] Specifically, the connecting rod member 202c includes a first connecting block 202c-1 connected to the bottom of the bucket 201a, a U-shaped connecting rod 202c-2 arranged on the first connecting block 202c-1, a movable connecting rod 202c-3 arranged at the bottom of the U-shaped connecting rod 202c-2, a second connecting block 202c-4 arranged at the bottom of the opening and closing plate 202a, a third connecting block 202c-5 arranged at the bottom of the bucket 201a, and a swinging connecting rod 202c-6 connected to both the third connecting block 202c-5 and the movable connecting rod 202c-3. The first connecting block 202c-1 is rotatably connected to the end of the U-shaped connecting rod 202c-2; the end of the U-shaped connecting rod 202c-2 is rotatably connected to the end of the movable connecting rod 202c-3; the movable connecting rod 202c-3 is rotatably connected to the swinging connecting rod 202c-6; the swinging connecting rod 202c-6 is rotatably connected to the third connecting block 202c-5. Among them, in this embodiment, when the end of the swinging connecting rod 202c-6 rotates counterclockwise at the connection with the third connecting block 202c-5, it drives the movable connecting rod 202c-3 to move, pushing the U-shaped connecting rod 202c-2 to rotate counterclockwise along the first connecting block 202c-1, so that the opening and closing plate 202a placed parallel at the bottom of the bucket 201a can be closely combined with the bucket 201a.

[0048] Further, the commutation member 202d includes a fourth connection block 202d-1 disposed at the bottom of the bucket 201a, an upright rod 202d-2 disposed on the fourth connection block 202d-1, a support platform 202d-3 disposed on the side of the upright rod 202d-2, and a spring 202d-4 connected to both the support platform 202d-3 and the bucket 201a; the upright rod 202d-2 is rotatably connected to the fourth connection block 202d-1. Wherein, in this embodiment, the upright rod 202d-2 moves clockwise following the bucket 201a. When the upright rod 202d-2 contacts the arc plate 202b, it will cause the upright rod 202d-2 to rotate clockwise along with the fourth connection block 202d-1. The upright rod 202d-2 is rotatably connected to the middle of the swing connecting rod 202c-6, so it will drive the swing connecting rod 202c-6 to move counterclockwise.

[0049] The remaining structures are the same as those in Embodiment 2.

[0050] Operation process: The upright rod 202d-2 moves clockwise following the bucket 201a. When the upright rod 202d-2 contacts the arc plate 202b, it will cause the upright rod 202d-2 to rotate clockwise along with the fourth connection block 202d-1. The upright rod 202d-2 is rotatably connected to the middle of the swing connecting rod 202c-6, so it will drive the swing connecting rod 202c-6 to move counterclockwise. When the end of the swing connecting rod 202c-6 rotates counterclockwise at the connection with the third connection block 202c-5, it drives the movable connecting rod 202c-3 to move, pushing the U-shaped connecting rod 202c-2 to rotate counterclockwise along the first connection block 202c-1, so that the opening and closing plate 202a placed parallel to the bottom of the bucket 201a can be tightly combined with the bucket 201a.

[0051] When the bucket 201a is excavating, the opening and closing plate 202a is closed to prevent large pieces of minerals from entering the bucket 201a. When it is necessary to throw the minerals in the bucket 201a into the constant flow component 102, the opening and closing plate 202a is opened to make it easier for the minerals to enter the constant flow mechanism.

[0052] Embodiment 4

[0053] Refer to Figure 4, what is different from the above embodiments in this embodiment is that the constant-flow component 102 includes an inclined funnel 102a connected to one end of the connecting shaft 101a, a main shaft notch 102b opened at the bottom of the inclined funnel 102a, a small main shaft 102c disposed in the main shaft notch 102b, blades 102d disposed on the small main shaft 102c, and a small motor 102e disposed on one side of the small main shaft 102c. Among them, in this embodiment, when minerals appear in the inclined funnel 102a, the small motor 102e drives the main shaft and the blades 102d disposed on the main shaft to rotate at a constant speed, and quantitatively transports the crushed minerals to the conveyor belt below.

[0054] The remaining structures are the same as those in Embodiment 3.

[0055] Operation process: The small motor 102e drives the main shaft and the blades 102d disposed on the main shaft to rotate at a constant speed, and quantitatively transports the crushed minerals to the conveyor belt below; reduces the number of heavy-load starts and stops of the coal conveyor belt, extends the service life of the equipment, and avoids the occurrence of coal spilling and coal jamming.
