DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0021] Please referring to FIGS. 1 to 11, the present invention provides a sand rake for picking up shellfish organisms T1 on the beach T. The sand rake includes a generally trapezoidal and broad filter body 1, which has an open filtering space 10 and is surrounded by a frame-shaped reinforcement piece 11 around all outer sides thereof. The reinforcement piece 11 is provided with at least one first mounting hole 110 at its front side, at least one second mounting hole 111 at its rear side, and at least one third mounting hole 112 between two second mounting holes 111. Additionally, the filter body 1 is provided with at least one fourth mounting hole 100 at its front side, at least one fifth mounting hole 101, at least one sixth mounting hole 102, and at least one seventh mounting hole 103 at its front and rear sides, respectively. The at least one fourth mounting hole 100 corresponds to the at least one first mounting hole 110 on the reinforcement piece 11. The at least one fifth mounting hole 101 corresponds to the at least one second mounting hole 111 on the reinforcement piece 11. The at least one sixth mounting hole 102 corresponds to the at least one third mounting hole 112 on the reinforcement piece 11. Furthermore, the bottom side of the filter body 1 is formed as a flat surface 12, while the front side is formed as an inclined surface 13 and has a top edge with a plurality of teeth 14. The teeth 14 are generally serrate in a sand shovel style and are arranged in a uniform spacing configuration. A plurality of concave grooves 140 connect the adjacent teeth 14, and both the top edge of the teeth 14 and the bottom edge of the grooves 140 are designed to be flat surfaces 141. The filter body 1 has a plurality of filtering holes 15 distributed across all sides thereof.

[0022] The sand rake further includes a support component 2 consisting of at least one horizontal member 20 and positioned within the filtering space 10 of the filter body 1. The support component 2 has a sloping end 21 and a straight end 22 at its two ends, respectively. The sloping end 21 corresponds to the inclination angle of the inclined surface 13 at the front side of the filtering space 10 (as shown in FIG. 5), so that the sloping end 21 and straight end 22 of the support component 2 can correspond to and be disposed on the front side and rear side of the filter body 1, respectively. The sloping end 21 of the support component 2 is provided with at least one eighth mounting hole 210, corresponding to the at least one fourth mounting hole 100 on the front side of the filter body 1 and the at least one first mounting hole 110 on the reinforcement piece 11. The straight end 22 of the support component 2 is provided with at least one ninth mounting hole 220, corresponding to the at least one fifth mounting hole 101 on the rear side of the filter body 1 and the at least one second mounting hole 111 on the reinforcement piece 11.

[0023] Moreover, the sand rake of the present invention further includes a handle 3, installed on the rear side of the filter body 1. The handle 3 is constituted by an upper rod 30, a lower rod 31, and a middle rod 32 connecting the upper rod 30 and the lower rod 31. The upper rod 30, the lower rod 31 and the middle rod 32 are configured as a detachable structure. The top end of the upper rod 30 is equipped with a T-shaped grip 300. The lower rod 31 is provided with at least one tenth mounting hole 310 and at least one eleventh mounting hole 311. The at least one tenth mounting hole 310 on the lower rod 31 corresponds to the at least one third mounting hole 112 on the reinforcement piece 11 and the at least one sixth mounting hole 102 on the rear side of the filter body 1. The at least one eleventh mounting hole 311 on the lower rod 31 corresponds to the at least one seventh mounting hole 103 on the rear side of the filter body 1.

[0024] During assembly, first, at least one first mounting member 4 is assembled into the at least one eighth mounting hole 210 and the ninth mounting hole 220 on the support component 2, the at least one fourth mounting hole 100 and the at least one fifth mounting hole 101 on the filter body 1, and the at least one first mounting hole 110 and the at least one second mounting hole 111 on the reinforcement piece 11. As such, the support component 2 can be assembled within the filtering space 10 of the filter body 1, and the reinforcement piece 11 surrounds and is assembled on the outer side of the filter body 1.

[0025] Additionally, at least one second mounting member 5 is threaded through the at least one tenth mounting hole 310 on the lower rod 31 of the handle 3, the at least one third mounting hole 112 on the reinforcement piece 11, and the at least one sixth mounting hole 102 on the filter body 1. Then, at least one third mounting member 6 is threaded through the at least one eleventh mounting hole 311 on the lower rod 31 of the handle 3 and the at least one seventh mounting hole 103 on the filter body 1.

[0026] By the aforementioned assembly, the handle 3, the reinforcement piece 11, the support component 2 and the filter body 1 are assembled into a stable fixed relationship. The bottom side of the filter body 1 is designed as a flat surface 12, allowing the sand rake to stand upright and saving storage space.

[0027] Further illustration of the operating procedure, the user can tilt the filter body 1 by holding the grip 300 and direct the top edge of the plurality of teeth 14 towards the beach T to press the inclined surface 13 at the front side of the filter body 1 against the beach T (as shown in FIG. 9), followed by back-and-forth motion to dig into the beach T. Once there are shellfish organisms T1 in the path of the filter body 1, they will be exposed on the surface of the beach T and collected into the filtering space 10 of the filter body 1 as the teeth 14 on the top edge of the filter body 1 pass over them. When shellfish organisms T1 are collected, the user can lift the handle 3 and the filter body 1 upward. After the filtering space 10 of the filter body 1 contains a certain quantity of shellfish organisms T1, the filter body 1 can be immersed in seawater for washing. This process allows sand and mud T2 on the surface of the shellfish organisms T1 to flow out of the filter body 1 along with seawater through the plurality of filtering holes 15 (as shown in FIG. 10), leaving only the shellfish organisms T1 in the filtering space 10 of the filter body 1 (as shown in FIG. 11). This procedure can be repeated to effectively collect shellfish organisms T1 from the beach T.

[0028] It is worth mentioning that the handle 3 is designed as a detachable structure, consisting of the upper rod 30, the lower rod 31 and the middle rod 32. Therefore, users can adjust the length of the handle 3 as needed during excavation. When it is necessary to shorten the handle 3, the assembly of the middle rod 32 can be omitted (as shown in FIG. 7), and only the upper rod 30 and the lower rod 31 need to be assembled. On the contrary, if it is necessary to increase the length of the handle 3, the middle rod 32 can be assembled between the upper rod 30 and the lower rod 31 (as shown in FIG. 3). Moreover, there is no limitation to having only a single middle rod 32. Additionally, in the present invention, the top of the handle 3 is designed with an ergonomically T-shaped grip 300 for power-saving and enhanced maneuverability during the operation of the handle 3. This design significantly reduces perceived weight and fatigue, even during extended periods of collecting shellfish organisms T1, thus improving collection efficiency. Furthermore, the entire sand rake of the present invention is made of 304 stainless steel material, ensuring resistance to oxidation even when exposed to seawater.

[0029] In addition, the support component 2 assembled within the filtering space 10 of the filter body 1 can further increase the overall strength of the filter body 1. The quantity of the support component(s) 2 can be chosen based on practical considerations. As shown in FIG. 3, two horizontal members 20 are used as the support components 2 and assembled inside the filter body 1, while as shown in FIG. 8, a single horizontal member 20 is used as the support component 2 and assembled inside the filter body 1. The present invention prefers the use of two horizontal members 20 for assembly, but it is not limited thereto.

[0030] In summary, the sand rake of the present invention offers the following advantages compared to the prior art.

[0031] First, the special structure of the filter body 1 of the sand rake replaces the need for using one's hand to pick up shellfish organisms. This not only allows for the excavation of a larger area, increasing the yield, but also prevents injury to the hand from shellfish organisms T1, thus improving efficiency and safety.

[0032] Second, the handle 3 of the sand rake is designed with a detachable structure, allowing users to adjust its length according to the situation.

[0033] This can prevent users from bending over excessively when the handle 3 is too long, saving energy. Additionally, the filter body 1 with serrated teeth 14 allows for quick and efficient excavation. The multiple filtering holes 15 in the filter body 1 allow sand and mud to flow out, avoiding prolonged immersion of the user's hand in seawater and increasing comfort.
