[0002] Anchors are heavy equipment fixed to the stern or bow of a ship, usually made of iron or steel. The function of an anchor is to fix the ship to the water surface to prevent it from being washed away by waves or wind. Anchors can allow ships to moor or dock at sea, and can also help ships maintain their course and stability when needed. At present, most of the production of anchors is in the form of traditional sand core casting. After casting, the gravel attached to the casting will be removed for the convenience of subsequent processing.

[0003] For example, the Chinese utility model patent with patent number 202320485798.8 provides a counterweight casting sand cleaning device. By setting a knocking device, the inside of the equipment can be sand cleaned. The gear set drives the knocking hammer and rubber pad to knock on the equipment. The knocking frequency is relatively fixed. On the one hand, it can clean the sand, and at the same time, the rubber pad can protect the equipment.

[0004] However, the existing casting sand cleaning casting is mostly suitable for sand cleaning of smaller workpieces, and is not convenient for sand cleaning of larger castings such as anchors. Therefore, in view of this, a sand cleaning device for anchor castings is proposed to solve the above technical problems. Utility Model Content

It is necessary to point out that the following specific implementation methods are only used to further illustrate the utility model and cannot be understood as limiting the scope of protection of the utility model. Technical personnel in this field can make some non-essential improvements and adjustments to the utility model based on the above application content.

[0035] Example:

[0036] like Figure 1 , 2 As shown in Figure 3, the utility model provides a sand cleaning device for anchor castings, including a carrier frame 101, a support frame 104 is arranged on the carrier frame 101, multiple groups of receiving rollers 102 are arranged in parallel at intervals on the carrier frame 101, and a sand storage frame 103 is arranged at the bottom of the carrier frame 101. A mounting frame 109 is slidably arranged on the support frame 104, a guide rod 105 is arranged on the support frame 104, a mounting frame 106 is slidably sleeved on the guide rod 105, a mounting rod 107 is arranged on one side of the mounting frame 109, and the mounting rod 107 is slidably arranged in the mounting frame 106 along its axis, the axis of the mounting rod 107 is perpendicular to the guide rod 105, and a handle 108 is arranged at the end of the mounting rod 107.

[0037] When the device is in use, a large casting to be cleaned of sand, such as an anchor, is placed on a carrier frame 101, and the casting is supported by multiple sets of receiving rollers 102, which facilitates the placement and removal of the casting. After placement, the mounting frame 106 can be driven to slide along the guide rod 105 by holding the handle 108, and the mounting rod 107 can slide in the mounting frame 106, so that the mounting frame 109 can move at any position on the plane, thereby cleaning the sand of irregular castings.

[0038] like Figure 2 , 3 As shown, in this embodiment, a rotatable mounting shaft 201 and a linkage shaft 402 are provided on the mounting frame 109, a percussion hammer 204 is provided at the end of the mounting shaft 201, and a blast assembly is provided on the linkage shaft 402. A rotatable mounting shaft 201 and a linkage shaft 402 are provided on the mounting frame 109, a percussion hammer 204 is provided at the end of the mounting shaft 201, a driving assembly connected to the mounting shaft 201 is provided on the mounting frame 109, and the mounting shaft 201 is driven to reciprocate by the driving assembly. The driving assembly includes a steering gear 301 fixedly provided on the mounting frame 109, a driving plate 302 is provided on the output shaft of the steering gear 301, a torsion spring 202 is sleeved on the mounting shaft 201, one end of the torsion spring 202 is fixedly connected to the mounting shaft 201, and the other end abuts against the mounting frame 109, a driving rod 203 is provided at the end of the mounting shaft 201, and the driving plate 302 can abut against the driving rod 203 when rotating along the output shaft of the steering gear 301.

[0039] When in use, the servo 301 is controlled to start and drive the driving plate 302 to rotate along the output shaft of the servo 301. During the movement, the driving plate 302 drives the installation shaft 201 to rotate along its axis through the contact between its side and the driving rod 203, so that the percussion hammer 204 swings and controls the deformation of the torsion spring 202. When the driving plate 302 continues to move until it is separated from the driving rod 203, the installation shaft 201 is controlled to reverse and reset under the reset ability of the torsion spring 202 until the percussion hammer 204 hits the casting. Through the setting of this structure, the percussion hammer 204 can be used to hit irregular percussion surfaces, thereby improving the practicality of the device.

[0040] like Figure 2 , 3 As shown, in this embodiment, a blast assembly is arranged on the linkage shaft 402, and the blast assembly includes a high-pressure jet head 404 arranged on the linkage shaft 402. A blower 401 is arranged on the mounting frame 109, and the blower 401 is connected to the high-pressure jet head 404 through a pipe made of a flexible material. A linkage assembly connected to the linkage shaft 402 is arranged on the mounting shaft 201, and the rotation of the mounting shaft 201 is converted into a reciprocating rotation of the driving linkage shaft 402 through the linkage assembly. The linkage assembly includes a first gear 205 arranged on the mounting shaft 201, and a second gear 403 meshing with the first gear 205 is arranged on the linkage shaft 402, and the diameter of the second gear 403 is smaller than the diameter of the first gear 205.

[0041] The mounting shaft 201 drives the first gear 205 to rotate during the rotation process, and then drives the linkage shaft 402 to rotate synchronously back and forth through the engagement of the first gear 205 and the second gear 403, and the rotation amplitude of the linkage shaft 402 is greater than the rotation amplitude of the mounting shaft 201. The linkage shaft 402 drives the high-pressure jet head 404 to swing back and forth during the rotation process, and air is blown into the high-pressure jet head 404 through the blower 401 and the air is ejected to remove the sand attached to the casting. The movement of the striking hammer 204 can effectively clean the sand from the casting, thereby improving the sand cleaning effect of the device.

[0042] Specific usage and beneficial effects of the utility model:

[0043] When the device is used, a workpiece with a large volume to be sand-cleaned is placed on the carrier 101, and the installation frame 109 is controlled to slide horizontally on the support frame 104 and driven to move along the axis of the installation rod 107, so as to clean the sand at different positions on the large anchor. During the sand-cleaning process, the driving plate 302 is driven to move by the steering gear 301, and the driving plate 302 controls the reciprocating movement of the installation shaft 201 through the cooperation of the driving rod 203 and the torsion spring 202 during the movement, so as to drive the percussion hammer 204 to strike the anchor, so as to clean the sand from the anchor, and the linkage shaft 402 is controlled to reciprocate through the meshing of the first gear 205 and the second gear 403, and the sand on the anchor is further removed through the high-pressure jet head 404 on the linkage shaft 402, so as to improve the effect of sand-cleaning. The sand-cleaning device can be used to clean the sand of large castings such as anchors, and the sand-cleaning is more efficient.
