Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of a rotary tool assembly, and in particular to a rotary tool assembly. BACKGROUND

[0002] With the development of science and technology, in the process of underwater operation, it is necessary to recover the underwater objects to be recovered. In the prior art, the existing recovery device usually needs to use a suction pump to transport the objects to be recovered to a collection tank through a recovery pipe. However, the underwater environment is complex, and the materials, shapes and toughness of the objects to be recovered are quite different. For example, plastic woven bags, fiber ropes, waterweeds and hard shells. The larger size objects to be recovered cannot pass through the recovery pipe. Therefore, the larger size objects to be recovered block the recovery pipe, resulting in poor recovery effect of the existing recovery device. SUMMARY

[0003] The purpose of the present application is to provide a rotary tool assembly. The underwater robot main body is provided with a first supporting arm and a second supporting arm. The second supporting arm is swingably connected to the first supporting arm. The second supporting arm is provided with a receiving cavity. The rotary blade module includes a rotating shaft and a blade piece. The rotating shaft is rotatably connected to the second supporting arm and rotates along the axis of the rotating shaft. The blade piece is connected to the rotating shaft and rotates with the rotation of the rotating shaft. The end of the blade piece is provided with a blade part which grinds the objects to be recovered during rotation. The rotating shaft is provided with a first through hole, and the blade piece is provided with a second through hole which communicates with the first through hole. The recovery pipe is connected to the second supporting arm and communicates with the first through hole and the second through hole. The recovery pipe is connected to an external pump and forms a negative pressure under the driving of the external pump, so that the objects to be recovered are recovered along the second through hole, the first through hole and the inner cavity of the recovery pipe. At the same time, the blade part grinds the objects to be recovered during rotation, so as to grind the objects to be recovered through the blade part, thereby reducing the volume of the objects to be recovered and avoiding the blockage of the recovery pipe by the larger size objects to be recovered. The compacted silt also has the effect of breaking and loosening, thereby improving the recovery effect of the rotary tool assembly.

An electric cylinder 13 is provided between the second arm 12 and the first arm 11. The mounting end of the electric cylinder 13 is hinged to the first arm 11, and the output end of the electric cylinder 13 is hinged to the second arm 12.

[0047] Please refer to the attached document. Figs. 1-3 In this embodiment, the second support arm 12 is provided with a first hinged support arm 121 and a second hinged support arm 122; the first hinged support arm 121 and the second hinged support arm 122 are stacked in a horizontal direction; the first hinged support arm 121 protrudes from the peripheral sidewall of the second support arm 12 and is hinged to the first support arm 11; the second hinged support arm 122 protrudes from the peripheral sidewall of the second support arm 12 and is located at a different position from the first hinged support arm 121 on the second support arm 12; the second hinged support arm 122 is hinged to the output end of the electric cylinder 13, so that the second support arm 12 is hinged to the output ends of the first support arm 11 and the electric cylinder 13 respectively through the first hinged support arm 121 and the second hinged support arm 122, thereby facilitating the flexible swing of the second support arm 12 relative to the output ends of the first support arm 11 and the electric cylinder 13, thereby facilitating the unrestricted rotation of the second support arm 12.

[0048] Please refer to the attached document. Figs. 1-3In this embodiment, the rotating shaft 21 is built into the receiving cavity 12a so that the rotating shaft 21 is located inside the second support arm 12 through the receiving cavity 12a. The rotating shaft 21 is connected to the second support arm 12 through a bearing and rotates relative to the second support arm 12, which improves the smoothness of the rotation of the rotating shaft 21 relative to the second support arm 12. At the same time, the rotating shaft 21 is sealed to the second support arm 12. The peripheral sidewall of the rotating shaft 21 rotates with the rotation of the rotating shaft 21 and forms a sealed connection structure with the inner sidewall of the rotating hole of the second support arm 12, which ensures the sealing effect at the connection between the rotating shaft 21 and the second support arm 12 and prevents liquid from entering the second support arm 12 through the connection between the rotating shaft 21 and the second support arm 12.

[0049] The lower end of the rotating shaft 21 extends beyond the second support arm 12 so that the lower end of the rotating shaft 21 is exposed on the lower side of the second support arm 12.

By arranging multiple blade portions 221, the shredding efficiency of the blade member 22 relative to the object to be recycled is increased. A through hole 221a is formed between two adjacent blade portions 221. There are multiple through holes 221a, which are connected to a second through hole 22a in a ring direction and allow external objects to be recycled to pass through. The multiple through holes 221a are connected to a first through hole 21a and the inner cavity of the recycling pipe 30 in sequence through the second through hole 22a, so that the shredded objects to be recycled can flow sequentially through the multiple through holes 221a, the second through hole 22a, and the first through hole 21a to the inner cavity of the recycling pipe 30, thus avoiding the shredded objects from clogging the blade portion 221.

A second through hole 22a is provided in the blade connecting seat 222. The diameter of the second through hole 22a is larger than the diameter of the first through hole 21a, ensuring that the middle part of the blade connecting seat 222 is in a through state so that the shredded object to be recycled can pass through the blade connecting seat 222 and enter the first through hole 21a.

[0052] Please refer to the attached document. Figs. 1-5In this embodiment, the blade connecting seat 222 is detachably connected to the rotating shaft 21; this allows the blade connecting seat 222 to connect to or disconnect from the rotating shaft 21, thereby facilitating the connection or disconnection of the blade component 22 and improving the ease of mounting and dismounting the blade component 22. Optionally, the blade connecting seat 222 is detachably connected to the rotating shaft 21 via a snap-fit ​​mechanism.

[0053] Please refer to the attached document. Figs. 1-5 The inner wall of the blade connecting seat 222 forming the second through hole 22a is provided with a guide groove 222a. The guide groove 222a is arranged in an inclined direction so that the shredded object to be recycled can enter the second through hole 22a under the guidance of the guide groove 222a. There are multiple guide grooves 222a, which are arranged in an annular direction. The guide grooves 222a are arranged in a V-shaped groove and extend along the blade part 221 toward the rotating shaft 21. By arranging multiple guide grooves 222a, the smoothness of recycling the shredded object to be recycled is increased.

[0054] Please refer to the attached document. Figs. 1-5 In this embodiment, the circumferential sidewall of the rotating shaft 21 is provided with a first transmission part 211, which is located in the receiving cavity 12a; the second support arm 12 is connected to a power module 123, which includes a power motor 1231 and a second transmission part 1232.

[0055] Please refer to the attached document. Figs. 1-5 In this embodiment, the power motor 1231 is disposed on the outer side of the second support arm 12, and the mounting end of the power motor 1231 is sealed to the second support arm 12, ensuring the sealing effect between the power motor 1231 and the second support arm 12, preventing liquid from entering the inner side of the second support arm 12 through the connection between the power motor 1231 and the second support arm 12. The output end of the power motor 1231 is located in the receiving cavity 12a and is connected to the second transmission part 1232 in the receiving cavity 12a.
