In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

The embodiment of the invention provides a sand removal tool for a rotary channel, which can be applied to removing residual sand of the rotary channel of a casting device, and is shown in figure 1, and the sand removal tool comprises:

a vibration pump 11;

the rotary motor base 12 is fixedly connected to the vibration pump and is driven by the vibration pump to vibrate;

the bidirectional rotating motor 13 is positioned above the rotating motor base, rotates clockwise or anticlockwise, and is driven to vibrate by the rotating motor base;

the spring wire 14 is of a spiral structure and is positioned in a threaded hole 15 fixed on the bidirectional rotating motor 13, and the bidirectional rotating motor 13 rotates to control the spring wire to move forwards or backwards relative to the rotary channel;

during the process that the spring wire 14 moves forwards or backwards relative to the rotary channel, the residual sand on the inner cavity wall of the rotary channel is cleaned through the friction between the spring wire 14 and the inner cavity wall of the rotary channel.

In the embodiment of the present invention, the vibration pump 11 vibrates in the preset direction at the preset frequency, as for the vibration frequency of the vibration pump or the vibration frequency is constant or variable, or the vibration direction of the vibration pump 11 is constant or variable, the vibration frequency may be set according to actual requirements, and the vibration frequency is not specifically limited herein; it is noted that changes in the vibration direction or frequency can be made without inventive step, and still fall within the scope of the present invention.

In the embodiment of the present invention, the rotating electrical machine base 12 is fixed above the vibration pump 11, and corresponding first threaded holes or fastening structures may be respectively disposed on the rotating electrical machine base 12 and the vibration pump 11, and then the rotating electrical machine base 12 and the vibration pump 11 are fixed together, or the vibration pump 11 and the base 12 are integrally formed; alternatively, a threaded screw is provided on the vibration pump 11 or the base 12, and correspondingly, a corresponding first threaded hole is provided on the base 12 or the vibration pump 11, and the rotary electric machine base 12 and the vibration pump 11 are fixed by the screw and the threaded hole or an additional nut. When the vibration pump 11 vibrates, the rotating motor base 12 is driven to vibrate correspondingly.

In the embodiment of the present invention, the bidirectional rotating electrical machine 13 can rotate in both directions, i.e., can rotate clockwise or counterclockwise. In this embodiment, at least one second screw hole is fixed to the bidirectional rotary electric machine 13, into which the spring wire 14 having a spiral structure is inserted. In addition, the bidirectional rotary electric machine 13 can be driven by the rotary electric machine base 12 to vibrate when the vibration pump 11 drives the rotary electric machine base 12 to vibrate. That is, when the bidirectional rotary electric machine 13 is rotated clockwise or counterclockwise, the vibration may be generated by the vibration of the vibration pump 11.

In the embodiment of the present invention, the spring wire 14 is in a spiral structure, and the radius of the spiral structure corresponds to the aperture of the second threaded hole on the bidirectional rotating motor 13, so that the spring wire in the spiral structure extends into the second threaded hole of the bidirectional rotating motor and the thread of the spiral structure is matched with the thread of the second threaded hole, and the bidirectional rotating motor 13 controls the spring wire 14 in the spiral structure to move forward or backward relative to the convoluted passage. In the process that the spring wire 14 with the spiral structure moves forwards or backwards and vibrates under the driving of the vibration pump 11, the surface of the spring wire 13 rubs with the inner cavity wall of the rotary channel, and then residual sand on the inner cavity wall of the rotary channel is removed.

According to the sand removal tool for the convolute channel provided by the embodiment of the invention, under the vibration action of the vibration pump, the spring wire 13 in the spiral structure can vibrate, and when the rotating motor rotates clockwise or anticlockwise, the spring wire can move forwards or backwards relative to the convolute channel, so that residual sand on the inner cavity wall of the convolute channel can be effectively removed.

In one embodiment of the invention, the cross-section of the spring wire 13 is diamond shaped. The diameter of the cross-section may be around 1mm, such as 0.7mm to 1.2 mm. By the arrangement, residual sand attached or adhered to the inner cavity wall of the rotary channel can be removed better, so that the yield of casting devices is ensured.

In an embodiment of the present invention, the material of the spring wire is stainless steel, the spring wire is wound into a spiral structure, the diameter of the spiral structure can be set according to the diameter of the convoluted channel, for example, the diameter can be 3mm to 8mm, and the pitch between two adjacent spiral sections is 2mm to 3 mm.

In one embodiment of the present invention, the spiral structure around which the spring wire is wound includes a tapered head portion disposed at an end near an entrance of the convoluted passage to facilitate the entry of the spring wire of the spiral structure into the narrow convoluted passage.

Further, in one embodiment of the present invention, at least one position sensor is provided at a tip of the head of the spiral structure of the spring wire for detecting a position of the head of the spiral structure; the sand removal tool also comprises a controller which is respectively electrically connected with the position sensor and the vibration pump and is used for controlling and switching the vibration frequency of the vibration pump when the position of the head reaches a first preset position; and controlling the rotating motor to switch the rotating direction when the position of the head reaches a second preset position.

In this embodiment, the controller may control the vibration frequency of the vibration pump 11 and the rotation direction of the bidirectional rotary motor 13 according to the position of the head of the spiral structure, for example, when it is detected by the position sensor that the head of the spring wire has been extended from the outlet of the circular passage, the controller may control the rotation direction of the bidirectional rotary motor 13 to be changed, and when it is detected by the position sensor that the head of the spring wire has been extended into the inlet of the circular passage by a predetermined depth, the controller may control the vibration frequency of the vibration pump to be switched to a higher frequency, so as to better remove the residual sand from the inner cavity wall of the circular passage.

In one embodiment of the present invention, the sand removal tool further comprises a first socket electrically connected to the vibration pump 11 for connecting the vibration pump 11 to a power source.

In one embodiment of the invention, the grit removal tool further comprises a second socket connected to the reversible electric motor 13 for connecting the reversible electric motor 13 to a power source.

In one embodiment of the invention, as shown in fig. 2, at least one spring structure 16 is provided between the rotating machine base 12 and the bidirectional rotating machine 13. When the vibration pump 11 vibrates, the spring structure 16 can drive the bidirectional rotating motor 13 and the spring wire 14 in the second threaded hole of the bidirectional rotating motor 13 to swing under the action of inertia, so that the contact friction times and friction force between the surface of the spring wire and the inner cavity wall of the rotary channel are improved, and residual sand remained on the inner cavity wall of the rotary channel can be efficiently removed.
