[0027] Please refer to Figure 1. The raking device in one embodiment includes a base 100, a raking mechanism 200 and a guide mechanism 300. The base 100 has a guide groove 101. The raking mechanism 200 is movably disposed on the base 100 along a first direction. The guide mechanism 300 is fixed to the raking mechanism 200 and is at least partially accommodated in the guide groove 101.

[0028] When the raking mechanism 200 moves relative to the base 100 along a first direction, the guide mechanism 300 cooperates with the guide groove 101 to guide along the first direction, where the first direction is the length direction of the guide groove 101 .

[0029] It should be noted that the first direction is the X direction shown in Fig. 1. The raking mechanism 200 is movably disposed on the base 100 along the first direction, that is, the raking mechanism 200 can move relative to the base 100 along the first direction.

[0030] The above-mentioned sand raking device, when the sand raking mechanism 200 moves along the first direction relative to the base 100, the guide mechanism 300 cooperates with the guide groove 101 to guide along the first direction, which can realize the sand raking function and effectively prevent the sand raking mechanism 200 from deviating during movement, which is beneficial to improving the reliability and safety of the operation of the sand raking device.

[0031] In this embodiment, the guide mechanism 300 and the raking mechanism 200 are split structures, and the guide mechanism 300 and the raking mechanism 200 are detachably connected to facilitate timely maintenance and replacement of the two. In other embodiments, the guide mechanism 300 and the raking mechanism 200 can also be an integrated structure.

[0032] Specifically, please refer to Figure 2 As shown in FIG. 3 , the guide mechanism 300 includes a connecting shaft 310 and a guide member 320 . One end of the connecting shaft 310 is fixedly connected to the sand raking mechanism 200 , and the other end of the connecting shaft 310 is fixedly connected to the guide member 320 . The guide member 320 is at least partially accommodated in the guide groove 101 .

[0033] It is understandable that the guide member 320 is fixedly connected to the sand raking mechanism 200 via the connecting shaft 310. When the sand raking mechanism 200 moves in the first direction relative to the base 100, the guide member 320 cooperates with the guide groove 101 in guiding along the first direction. In this way, the guide member 320 can be installed and fixed without hindering the operation of the sand raking mechanism 200.

[0034] In this embodiment, the connecting shaft 310 is cylindrical. In other embodiments, the connecting shaft 310 can also be prismatic or other shapes. Here, the shape of the connecting shaft 310 is not specifically limited.

[0035] In this embodiment, one end of the connecting shaft 310 is detachable from the sand raking mechanism 200, for example, a detachable connection can be achieved by threading, plug-in or other methods; the other end of the connecting shaft 310 is not detachable from the guide member 320, for example, a non-detachable connection can be achieved by welding, riveting or other methods.

[0036] More specifically, please refer to Figure 4. The guide member 320 includes a wheel body 321, a bearing portion 322 and a step portion 323. The other end of the connecting shaft 310 is inserted into the step portion 323, and the step portion 323 is connected to the bearing portion 322. The wheel body 321 is sleeved outside the bearing portion 322 and accommodated in the guide groove 101; when the sand raking mechanism 200 moves along the first direction relative to the base 100, the wheel body 321 can roll relative to the guide groove 101.

[0037] It should be noted that the bearing portion 322 includes an inner ring layer and an outer ring layer, the outer ring layer is sleeved outside the inner ring layer and can rotate relative to the inner ring layer, the step portion 323 is fixedly connected to the inner ring layer, and the wheel body 321 is sleeved between the outer ring layers. When the raking mechanism 200 moves relative to the base 100 along the first direction, the wheel body 321 can roll relative to the guide groove 101 to reduce the wear caused by the direct contact between the wheel body 321 and the guide groove 101.

[0038] In this embodiment, the wheel body 321 is a polytetrafluoroethylene wheel, which can extend the service life of the wheel body 321 by more than one year compared to a nylon wheel, thereby greatly extending the service life of the wheel body 321 and helping to reduce the replacement frequency of the wheel body 321 .

[0039] In this embodiment, the step portion 323 is in the shape of a hollow ring, and has a slot for inserting the other end of the connecting shaft 310. The other end of the connecting shaft 310 is interference-fitted with the slot, so that the other end of the connecting shaft 310 is fixed to the step portion 323. In other embodiments, the step portion 323 may also be in the shape of a hollow prism or other shapes.

[0040] In this embodiment, the step portion 323 and the bearing portion 322 are separate structures, and the step portion 323 and the bearing portion 322 can be connected by welding or riveting. In other embodiments, the step portion 323 and the bearing portion 322 can also be an integrated structure.

[0041] Specifically in this embodiment, please refer to FIG. 4 , the thickness of the step portion 323 ranges from 10 mm to 11 mm.

[0042] It should be noted that the thickness of the step portion 323 is the dimension of the step portion 323 in the Z direction shown in Fig. 4. By limiting the thickness of the step portion 323 to an optimal range, the wheel body 321 can be placed in a suitable position in the height direction, preventing the wheel body 321 from rubbing against the bottom wall of the guide groove 101 due to the wheel body 321 being too low, causing the wheel body 321 to wear and even causing the sand raking mechanism 200 to be unable to operate normally, and preventing the wheel body 321 from being unable to cooperate with the guide groove 101 due to the wheel body 321 being too high.

[0043] In this embodiment, the thickness of the step portion 323 ranges from 10 mm to 11 mm, which can meet the use requirements. In other embodiments, the thickness of the step portion 323 can also range from other numerical ranges.

[0044] Please refer to FIG3 , in the second direction, the wheel body 321 and the side wall of the guide groove 101 are provided with a first gap 321a, and the second direction intersects with the first direction. It should be noted that the second direction is the Y direction shown in FIG3 , that is, the width direction of the guide groove 101. Through the above arrangement, when the raking mechanism 200 is running, it is possible to prevent the wheel body 321 from directly contacting the side wall of the guide groove 101, thereby reducing the wear of the wheel body 321.

[0045] In this embodiment, in the second direction, the guide groove 101 has two side walls that are opposite and spaced apart, and a first gap 321a is provided between the wheel body 321 and the two side walls, and the two first gaps 321a are of the same size, so as to improve the space utilization of the guide groove 101 and the sliding of the wheel body 321. In other embodiments, the sizes of the two first gaps 321a may also be different.

[0046] Specifically in this embodiment, please refer to FIG. 3 , the value range of the first gap 321 a is 1 mm to 2 mm.

[0047] It can be understood that by limiting the first gap 321a to the optimal range, the distance between the wheel body 321 and the side wall of the guide groove 101 can be optimized, preventing the wheel body 321 from swinging too much to the left and right due to the first gap 321a being too large, and preventing the wheel body 321 from being unable to slide due to the first gap 321a being too small.

[0048] In this embodiment, the value range of the first gap 321a is 1 mm to 2 mm, which can meet the use requirements. In other embodiments, the value range of the first gap 321a can also be other numerical ranges.

[0049] Please refer to FIG. 3 . In the third direction, a second gap 321 b is formed between the wheel body 321 and the bottom wall of the guide groove 101 . The third direction, the second direction and the first direction intersect in the space.

[0050] It should be noted that the third direction is the Z direction shown in Fig. 3, i.e., the height direction of the guide groove 101. Through the above arrangement, when the raking mechanism 200 is in operation, the wheel body 321 can be prevented from directly contacting the bottom wall of the guide groove 101, thereby reducing the wear of the wheel body 321 and the probability of collision between the wheel body 321 and the bottom wall of the guide groove 101.

[0051] In this embodiment, the third direction, the second direction and the first direction are perpendicular to each other in space. In other embodiments, the third direction, the second direction and the first direction can also be arranged at an angle other than 90 degrees in space.

[0052] Specifically in this embodiment, please refer to FIG. 3 , the value range of the second gap 321 b is 16 mm to 17 mm.

[0053] It can be understood that by limiting the second gap 321b to the optimal range, the distance between the wheel body 321 and the bottom wall of the guide groove 101 can be optimized, and the wheel body 321 can be prevented from directly contacting the bottom wall of the guide groove 101, thereby reducing the wear of the wheel body 321 and the probability of collision between the wheel body 321 and the bottom wall of the guide groove 101.

[0054] In this embodiment, the value range of the second gap 321b is 16 mm to 17 mm, which can meet the use requirements. In other embodiments, the value range of the second gap 321b can also be other numerical ranges.

[0055] Further, please refer to FIG. 4 , the guide member 320 further includes a dust cover 324 , the dust cover 324 is disposed on the bearing portion 322 , and the dust cover 324 has an avoidance groove for the step portion 323 to pass through.

[0056] It is understandable that the step portion 323 passes through the avoidance groove and is at least partially exposed outside the avoidance groove, so that the connecting shaft 310 is inserted into the step portion 323. By providing the dust cover 324, it is possible to prevent dust and other impurities from entering the bearing portion 322 and affecting the normal use of the bearing portion 322.

[0057] In this embodiment, the step portion 323 is cylindrical, and accordingly, the avoidance groove is a circular groove. In other embodiments, the step portion 323 can also be prism-shaped or other shapes, and accordingly, the avoidance groove can also be a square groove or other shapes.

[0058] In this embodiment, the dust cover 324 and the bearing portion 322 are separate structures, and the two can be fixed by welding or riveting. In other embodiments, the dust cover 324 and the bearing portion 322 can also be an integrated structure.

[0059] Please refer to Figure 2 The raking mechanism 200 includes a sprocket 210 , a scraper plate 220 and a fixing frame 230 , the connecting shaft 310 is fixed to the fixing frame 230 , the scraper plate 220 is fixed to the fixing frame 230 and is used for raking sand, and the sprocket 210 is installed on the fixing frame 230 and is movably disposed on the base 100 .

[0060] It can be understood that when a raking operation is required, the sprocket 210 is driven to move relative to the base 100, the sprocket 210 drives the fixed frame 230 to move, and the scraper plate 220 moves synchronously with the fixed frame 230, thereby realizing the raking operation; at the same time, the wheel body 321 of the guide mechanism 300 slides and rolls in the guide groove 101 to guide the movement of the scraper plate 220.

[0061] Specifically, please refer to Figure 2 The fixing frame 230 includes a transverse plate 231 and vertical plates 232 arranged at both ends of the transverse plate 231 , the scraper plate 220 is arranged on one side of the transverse plate 231 , the guide mechanism 300 is fixed to the middle of the transverse plate 231 , and the sprocket 210 is installed on the vertical plate 232 .

[0062] It should be noted that the scraper plate 220 is disposed on the top side of the horizontal plate 231, the connecting shaft 310 of the guide mechanism 300 is fixed to the middle of the horizontal plate 231, and the sprocket 210 is installed on the side of the vertical plate 232. In this way, the scraper plate 220, the connecting shaft 310 and the sprocket 210 can be smoothly installed on the fixing frame 230 without hindering the guiding cooperation between the wheel body 321 and the guide groove 101.

[0063] In this embodiment, the horizontal plate 231 is vertically connected to the vertical plate 232. In other embodiments, the horizontal plate 231 and the vertical plate 232 may also be arranged at an angle other than 90 degrees.

[0064] In this embodiment, the horizontal plate 231 and the vertical plate 232 are split structures, for example, they can be connected by welding or riveting. In other embodiments, the horizontal plate 231 and the vertical plate 232 can also be an integrated structure with good integrity and high mechanical strength.

[0065] More specifically, please refer to Figure 2 As shown in FIG. 1 , the base 100 includes a support frame 110 and two guide plates 120 . The two guide plates 120 are spaced apart on the support frame 110 . The two guide plates 120 and the support frame 110 are arranged to form a guide groove 101 .

[0066] It should be noted that the two guide plates 120 are arranged at intervals on the top side of the support frame 110 along the second direction, and the two guide plates 120 and the top side of the support frame 110 are arranged to form a guide groove 101 with a top opening, and the wheel body 321 of the guide mechanism 300 is accommodated in the guide groove 101. When the sand raking mechanism 200 moves along the first direction relative to the base 100, the wheel body 321 of the guide mechanism 300 cooperates with the guide groove 101 to guide along the first direction.

[0067] In this embodiment, the support frame 110 and the guide plate 120 are separate structures, and the support frame 110 and the guide plate 120 can be fixed by welding or riveting. In other embodiments, the support frame 110 and the guide plate 120 can also be an integrated structure.

[0068] In this embodiment, the support frame 110 is in a U-shaped structure, which is stable. In other embodiments, the support frame 110 can also be in a C-shaped structure or other shapes.

[0069] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
