[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Figure 1 This is a schematic diagram of the ore cleaning rake according to Embodiment 1 of the present invention; Figure 2 This is a side view of the ore cleaning rake according to Embodiment 1 of the present invention;

[0030] like Figure 1 , Figure 2 As shown, the ore cleaning rake proposed in this embodiment can be used to clean and gather ore of different sizes during mining construction, and can also be used to remove other debris.

[0031] This ore clearing rake includes a rake head 1 and a handle 2 connected together. The handle 2 is used by people to hold and rake the ground, and the rake head 1 is used to gather the ore on the ground.

[0032] In order to gather ore of different sizes, the rake head 1 includes a connecting rod 11, on which nail-shaped rake teeth 12 and saw-tooth rake teeth 13 are connected.

[0033] A rake head 1 contains both spike-shaped rake teeth 12 and serrated rake teeth 13, enabling it to perform multiple purposes. The spike-shaped rake teeth 12 have larger gaps between their teeth and are fine and long, making them suitable for gathering large, deeply piled ore particles; the serrated rake teeth 13 have smaller gaps between their teeth and are shorter and wider, making them suitable for gathering smaller, shallowly piled ore particles.

[0034] Specifically, the spiked rake teeth 12 and the sawtooth rake teeth 13 are connected end to end. The spiked rake teeth 12 include iron rods 121 evenly connected to the connecting rod 11, and the sawtooth rake teeth 13 include iron plates 131 connected to the side of the connecting rod 11 away from the iron rods 121, with sawtooth teeth 132 provided on the edge of the iron plates 131 away from the connecting rod 11.

[0035] Several iron rods 121 are arranged on the connecting rod 11 to form nail-shaped rake teeth 12. The spacing of the iron rods 121 is determined according to the working conditions to ensure that the nail-shaped rake teeth 12 can gather ore of medium to large volume. The sawtooth rake teeth 13 are almost on the same plane as the nail-shaped rake teeth 12. After using the nail-shaped rake teeth 12, they can be flipped over to use the sawtooth rake teeth 13, which is convenient and quick, saving the trouble of changing tools.

[0036] Several teeth are made on the iron plate 131 to form saw teeth 13. The size and shape of the teeth can be determined according to the working conditions. The area between the teeth should be smaller than that of medium-sized ore. If cleaning small ore piles that are deeply piled up, the saw teeth 132 can be inserted into the ore pile and the surface of the iron plate 131 can be used to gather them together, making the cleaning faster.

[0037] The handle 2 is connected to the middle of the connecting rod 11. The angle between the handle 2 and the spiked rake teeth 12 and the sawtooth rake teeth 13 can be set according to the working conditions. By flipping the handle 2, the spiked rake teeth 12 or the sawtooth rake teeth 13 can be selected.

[0038] In one specific embodiment of this utility model, the angle between the handle 2 and the nail-shaped rake teeth 12 and the saw-tooth rake teeth 13 is 90 degrees, which can easily rake the ore.

[0039] The connecting rod 11 can be made of thick steel plate, square steel pipe, or round steel pipe. In a specific embodiment of this utility model, the connecting rod 11 includes a first welded pipe, and the handle 2 includes a second welded pipe. The second welded pipe is vertically welded to the middle of the first welded pipe. The welded pipe is easy to obtain, and the diameter of the second welded pipe can be slightly smaller than the diameter of the first welded pipe, making it easy to grip.

[0040] In one specific embodiment of this utility model, to facilitate the insertion of the iron rod 121 into the ore pile, the iron rod 121 is a round steel bar with one end set as a cone, and the other end of the round steel bar is vertically welded to the first welded pipe. The diameter and hardness of the round steel bar are sufficient to ensure effective ore gathering, and the length of the round steel bar is determined according to the working conditions; it does not need to be too long, just long enough for ease of use. One end of the round steel bar is ground into a cone shape to facilitate insertion into the ore pile to rake the ore.

[0041] The width of the iron plate 131 can be the same as the length of the iron rod 121. The nail-shaped rake teeth 12 and the saw-tooth rake teeth 13 on both sides of the connecting rod 11 have the same width, making it convenient to use.

[0042] In one specific embodiment of this utility model, in order to ensure the firmness of the saw teeth 13, at least two reinforcing ribs 3 are welded between the side of the iron plate 131 facing the handle 2 and the connecting rod 11. The reinforcing ribs 3 are evenly arranged at the connection between the iron plate 131 and the connecting rod 11 to prevent the iron plate 131 from being tilted due to large resistance during the rakeing process.

[0043] In one specific embodiment of this utility model, the teeth of the saw 132 can be equilateral triangles, with an arc-shaped chamfer at the tooth tip. Equilateral triangles are sequentially cut along the edge of the iron plate 131 to form equilateral triangle teeth, creating equilateral triangle spaces between adjacent teeth. The teeth can be inserted into the ore pile to rake smaller ore particles. To reduce wear on the tooth tips, the tips are ground into an arc shape, facilitating insertion into the ore pile without damaging the tooth tips.

[0044] The distance between the tips of adjacent equilateral triangular teeth is smaller than the distance between adjacent iron rods 121, which makes it easier for the nail-shaped rake teeth 12 and the saw-tooth rake teeth 13 to be used for different sizes of ore.

[0045] The length of the connecting rod 11 can be set according to work needs, and can be around 50cm. The length of the handle 2 can be 120cm or more, which is convenient for workers to stand and use. A rubber pad 4 can be wrapped around the second welded pipe of the handle 2 to prevent the hand from slipping.

[0046] Example 2

[0047] Figure 3 This is a side view of the ore cleaning rake according to Embodiment 2 of the present invention;

[0048] like Figure 3 As shown, the ore cleaning rake provided in this embodiment, based on embodiment 1, has its nail-shaped rake teeth 12 and saw-tooth rake teeth 13 both set in an arc shape in order to facilitate digging up the ore after it is gathered.

[0049] Specifically, the iron rod 121 is bent towards the handle 2 at its middle section, forming a set angle greater than 160 degrees. The iron plate 131 is also bent towards the handle 2 at its middle section, forming a set angle greater than 160 degrees.

[0050] Each iron rod 121 is slightly bent to form a slightly curved nail-shaped rake tooth 12, which makes it easier to prevent large pieces of ore from falling during the transportation of the ore. However, the bending angle should not be too large to facilitate the rake operation.

[0051] The iron plate 131 is slightly bent to form a slightly curved serrated rake tooth 13, which makes it easier to prevent small pieces of ore from falling during transport. However, the bending angle should not be too large to facilitate rake operation. In this embodiment, the angle is set to 170 degrees.

[0052] The ore cleaning rake according to the present invention has been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the ore cleaning rake proposed in the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
