[0045] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0046] The ore crushing fork 100 of an embodiment of the present invention is described below with reference to the accompanying drawings. Figures 1 to 7 As shown, the ore crushing fork 100 according to an embodiment of the present invention includes a platform 1, a hand handle 2, a plurality of fork handles 3 and a plurality of scraper claws 4.

[0047] The platform 1 has a first end 11 and a second end 12 in a first direction. The hand handle 2 extends along the first direction and is located at the first end 11 of the platform 1.

[0048] Multiple forks 3 are spaced apart along a second direction, each fork 3 extends along a first direction, and each fork 3 includes a third end 31 and a fourth end 32. The third end 31 of each of the multiple forks 3 is located at the second end 12 of the platform 1, and the fourth end 32 of each of the multiple forks 3 is used to crush coal blocks.

[0049] Multiple scrapers 4 are spaced apart along a second direction, and the multiple scrapers 4 and multiple forks 3 are arranged side by side in a third direction, with any two of the first, second, and third directions being perpendicular to each other. At least a portion of each scraper 4 is arc-shaped, and each scraper 4 includes a fifth end 41 and a sixth end 42. The fifth end 41 of each of the multiple scrapers 4 is located at the second end 12 of the platform 1, and the sixth end 42 of the scraper 4 is located at the end of the scraper 4 away from the fork 3 in the third direction. The multiple scrapers 4 are used to grip coal blocks.

[0050] According to an embodiment of the present invention, the ore crushing fork 100 has multiple forks 3 and multiple scrapers 4 mounted on the second end 12 of the platform 1, and a hand-held handle 2 mounted on the first end 11 of the platform 1. This allows the operator to grip the hand-held handle 2 to crush and pick up coal blocks. Specifically, when it is necessary to crush coal blocks, the fourth end 32 of the fork 3 can be vertically hammered downwards to crush the coal blocks. The crushed coal blocks can be picked up using the scrapers 4. When the operator is stacking coal blocks, they can stand in the middle of the scattered coal blocks and pick up coal blocks in all directions with their feet as the center to stack the crushed coal blocks. Compared to the use of straight forks to stack coal blocks in related technologies, the ore crushing fork 100 of the present invention, with multiple forks 3 and multiple scrapers 4 mounted on the platform 1, enables the ore crushing fork 100 to have both coal crushing and coal picking functions, providing versatility and making it convenient for operators to use, saving time and effort, and thus improving work efficiency.

[0051] Therefore, the ore crushing fork 100 according to an embodiment of the present invention has the advantage of facilitating the crushing and stacking of coal blocks.

[0052] like Figures 1 to 7 As shown, the ore crushing fork 100 according to an embodiment of the present invention includes a platform 1, a hand handle 2, a plurality of fork handles 3 and a plurality of scraper claws 4.

[0053] The platform 1 has a first end 11 and a second end 12 in a first direction. Specifically, the platform 1 is used to connect and add counterweight to the hand handle 2, multiple forks 3, and multiple scrapers 4. The thickness direction of the platform 1 is the third direction, and the size of the platform 1 in the second direction (in the first direction) decreases along the direction adjacent to the first end 11. Any two of the first direction, the second direction, and the third direction are perpendicular to each other. For example, the platform 1 is trapezoidal, and the first end 11 is the part of the platform 1 with the smallest size in the second direction.

[0054] The first direction can be up and down, the second direction can be left and right, and the third direction can be front and back. The up and down, left and right, and front and back directions are shown by arrows in the figure. For example, the first end 11 is the upper end of the platform 1. The dimensions of the platform 1 increase from top to bottom in the left and right direction, and the thickness direction of the platform 1 is the front and back direction.

[0055] like Figures 1 to 4 As shown, the hand lever 2 extends along a first direction and is located at the first end 11 of the platform 1. For example, the hand lever 2 extends in a vertical direction and its lower end is located at the upper end of the platform 1.

[0056] like Figures 1 to 5As shown, in some embodiments, the first end 11 of the platform 1 is provided with a circular tube 15, which extends along a first direction. One end of the handheld lever 2 is provided with a threaded rod 21, which can extend into the circular tube 15 and be threadedly connected to it. Specifically, the cavity of the circular tube 15 has threads, and the cavity of the circular tube 15 is used to adapt and connect the handheld lever 2. Thus, the handheld lever 2 can be detachably connected to the circular tube 15, thereby allowing the handheld lever 2 to be detachably connected to the platform 1 via the circular tube 15. The other end of the handheld lever 2 is provided with a handle 24 for easy gripping by the operator.

[0057] A flange 22 is provided on the outer periphery of one end of the handle 2 adjacent to the threaded rod 21. The flange 22 is connected to the round tube 15 by a locking pin 23. Specifically, the end face of the round tube 1 facing away from the platform 1 in a first direction has multiple threaded holes, and the flange 22 has multiple through holes extending through it in the first direction. The locking pin 23 passes through the through holes on the flange 22 and is threadedly connected to the corresponding threaded holes on the round tube 15 so that the handle 2 and the round tube 15 are securely connected. For example, the upper end face of the round tube 15 has multiple threaded holes.

[0058] like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, multiple forks 3 are spaced apart along a second direction, and each fork 3 extends along a first direction. Each fork 3 includes a third end 31 and a fourth end 32. The third end 31 of each of the multiple forks 3 is located at the second end 12 of the platform 1, and the fourth end 32 of each of the multiple forks 3 is used for crushing coal. For example, multiple forks 3 are spaced apart along a left-right direction, and each fork 3 extends along a up-down direction. The third end 31 is the upper end of the fork 3 and is located at the second end 12 (lower end) of the platform 1. The third end 31 is the lower end of the fork 3 and is used for crushing coal.

[0059] In some embodiments, the fork 3 is provided with a plurality of crushing columns 5 spaced apart along a first direction, the extending direction of the crushing columns 5 forming an angle with the extending direction of the fork 3. Thus, when the fork 3 impacts the coal block, the plurality of crushing columns 5 on the fork 3 can contact the coal block, thereby improving the efficiency of crushing the coal block. For example, the fork 3 is provided with a plurality of crushing columns 5 spaced apart along a vertical direction.

[0060] like Figure 1 , Figure 2 , Figure 5 and Figure 7As shown, in some embodiments, the crushing column 5 is inclined in a direction away from the fork 3 and away from the platform 1. Specifically, the angle between the extending direction of the crushing column 5 and the extending direction of the fork 3 is greater than or equal to 30° and less than or equal to 60°. The acute angle formed by the crushing column 5 and the fork 3 is oriented away from the platform 1 in the first direction, thereby facilitating the impact of the end of the crushing column 5 on the coal block when the fork 3 impacts it. For example, the crushing column 5 is inclined downwards, and the angle between the extending direction of the crushing column 5 and the extending direction of the fork 3 is 45°.

[0061] In some embodiments, the crushing column 5 is located on the side of the fork 3 facing away from the scraper 4 in a third-party upward direction. For example, the crushing column 5 is located on the front side of the fork 3.

[0062] like Figure 7 As shown, in some embodiments, the crushing column 5 includes multiple sequentially connected columnar crushing segments 51. The maximum outer diameter of the multiple crushing segments 51 decreases sequentially in the direction away from the fork 3, and adjacent crushing segments 51 define an annular stepped groove 52. Specifically, each crushing segment 51 can be a variable-diameter column or a column with a constant outer diameter. The annular stepped groove 52 defined by adjacent crushing segments 51 facilitates the crushing of coal blocks when the crushing column 5 impacts them. For example, the outer diameter of each crushing segment 51 increases in the direction away from the fork 3, and a crushing tip is provided on the crushing segment 51 located at the end of the crushing column 5 away from the fork 3 (the outermost end). The outer diameter of the crushing tip first increases and then decreases in the extending direction of the crushing column 5.

[0063] like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, in some embodiments, the fourth end 32 of the fork 3 is provided with a crushing head 6, which is a column extending along a first direction, and the outer diameter of the crushing head 6 is larger than the outer diameter of the fork 3. Specifically, the crushing head 6 is used to directly impact the coal block in order to increase the service life of the fork 3. For example, the crushing head 6 is a cylinder or a polygonal prism.

[0064] In some embodiments, the outer peripheral surface of the crushing head 6 has a plurality of cutting grooves 61, which open on the side opposite to the fork 3 in a first direction. The openings of the cutting grooves 61 face away from the crushing head 6 and the platform 1, and the cutting grooves 61 facilitate cutting coal blocks, thereby facilitating the crushing head 6 to crush coal blocks. The cutting grooves 61 are formed on the outer peripheral surface of the crushing head 6 and the surface of the crushing head 6 facing away from the fork 3, and the cutting grooves 61 include arcuate surfaces; or, the cutting grooves 61 include a plurality of inclined surfaces intersecting the outer peripheral surface of the crushing head 6. For example, the cutting grooves 61 include two symmetrical inclined surfaces that intersect the outer peripheral surface of the crushing head 6.

[0065] like Figure 7As shown, in some embodiments, the crushing head 6 is a polygonal prism, and the cutting grooves 61 are formed at the connection points of multiple peripheral surfaces of the crushing head 6. For example, the crushing head 6 is a quadrangular prism, and each of the four edges of the quadrangular prism is provided with a cutting groove 61.

[0066] In some embodiments, the surface of the crushing head 6 facing away from the fork 3 in a first direction has a cutting cavity 62, and the opening of the cutting cavity 62 faces away from the fork 3 in the first direction. Specifically, the cutting cavity 62 communicates with the cutting groove 61 so that the surface of the crushing head 6 facing away from the fork 3 in the first direction is an irregularly shaped surface, thereby facilitating the crushing of coal blocks. For example, the lower surface of the crushing head 6 is provided with a cutting cavity 62, which is an irregularly shaped conical cavity.

[0067] like Figure 7 As shown, in some embodiments, on a cross-section perpendicular to the first direction, the projected area of ​​the cutting groove 61 increases in the first direction away from the fork 3, and the projected area of ​​the cutting cavity 62 increases in the first direction away from the fork 3. The outer periphery of the projected area of ​​the cutting cavity 62 is circular or polygonal. That is, the cross-sections of the cutting groove 61 and the cutting cavity 62 increase in the first direction away from the fork 3, thereby reducing the cross-sectional area of ​​the crushing head 6 (the portion having the cutting groove 61 and the cutting cavity 62) in the first direction away from the fork 3, in order to crush the coal. For example, the cross-sections of the cutting groove 61 and the cutting cavity 62 increase downwards, and the outer periphery of the cross-section of the cutting cavity 62 is polygonal.

[0068] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, multiple scraper claws 4 are spaced apart along a second direction, and the multiple scraper claws 4 and multiple forks 3 are arranged side by side in a third direction. For example, the multiple scraper claws 4 are spaced apart along a left-right direction, and the multiple scraper claws 4 are located behind the multiple forks 3. The scraper claws 4 have a J-shaped structure.

[0069] At least a portion of each scraper 4 is arc-shaped, and each scraper 4 includes a fifth end 41 and a sixth end 42. The fifth end 41 of each of the plurality of scrapers 4 is located at the second end 12 of the platform 1, and the sixth end 42 of the scraper 4 is located at the end of the scraper 4 away from the fork 3 in a third direction. The plurality of scrapers 4 are used to grip coal blocks. Specifically, the concave surface formed by the arc-shaped portion of each scraper 4 faces the platform 1 (hand lever 2) in a first direction, thereby facilitating the operator to use the plurality of scrapers 4 to grip coal blocks. For example, the sixth end 42 of the scraper 4 is located at the rear end of the scraper 4.

[0070] In some embodiments, the scraper 4 includes an arc-shaped segment and a straight segment. The end of the straight segment away from the arc-shaped segment constitutes the fifth end 41 of the scraper 4, and the end of the arc-shaped segment away from the straight segment constitutes the sixth end 42 of the scraper 4. Specifically, the end of the straight segment away from the arc-shaped segment is located at the second end 12 of the platform 1.

[0071] In some embodiments, the second end 12 of the platform 1 is provided with a crossbeam 13, which extends along a second direction. The fifth end 41 of the scraper 4 is rotatably disposed on the crossbeam 13. Multiple scrapers 4 and multiple forks 3 are arranged opposite each other in a third direction. Specifically, the straight section of the scraper 4, away from the arc-shaped section, is rotatably disposed on the crossbeam 13. The straight section of the scraper 4 and the corresponding fork 3 are arranged opposite each other in a third direction, so that the straight section of the scraper 4 can abut against the corresponding fork 3, thereby allowing the fork 3 to support the scraper 4. The crossbeam 13 is cylindrical, and the scraper 4 can rotate relative to the fork 3. When the fork 3 is used to strike the coal block, the scraper 4 can rotate circumferentially away from the fork 3 to prevent the scraper 4 from affecting the fork 3's impact on the coal block. When the scraper 4 is used to grab the coal block, the support rod 3 can support the corresponding scraper 4 so that the scraper 4 can grab the coal block.

[0072] In some embodiments, the crossbeam 13 is provided with an elastic element connected to the scraper 4, which can drive the scraper 4 to rotate in a direction away from the fork 3. Specifically, there are multiple elastic elements, each connected to a corresponding scraper 4. Thus, when the fork 3 strikes the coal block, the elastic element can drive the corresponding scraper 4 to rotate in a direction away from the fork 3, so as to prevent the scraper 4 from affecting the fork 3's impact on the coal block. When the scraper 4 grabs the coal block, the elastic element facilitates the scraper 4's grip on the ground, thereby facilitating the scraper 4's grabbing of the coal block.

[0073] In some embodiments, the elastic element is a torsion spring 14, which is sleeved on the crossbeam 13. Each torsion spring 14 is connected to a corresponding scraper 4 via a pull rod 43. For example, there are multiple torsion springs 14, which drive the scraper 4 to rotate away from the fork 3.

[0074] like Figure 1 and Figure 2 As shown, in some embodiments, the ore crushing fork 100 further includes a scraper 7 extending along a second direction. The scraper 7 is connected to the sixth end 42 of each of a plurality of scraper claws 4, and a wedge-shaped surface 71 is provided at the end of the scraper 7 away from the sixth end 42 of the scraper claw 4. Specifically, in a cross-section perpendicular to the second direction, the outer periphery of the projection of the scraper 7 is triangular, which facilitates the scraper 7 to be used for scraping buoyant coal deposits. At the same time, the scraper 7 can cut and level the mining roadway wall, providing multiple functions and convenient use, thus improving the effectiveness of the ore crushing fork 100.
