Technical Field

[0001] The utility model relates to the technical field of shakeout machines, and specifically relates to a new type of shakeout machine for separating castings. Background Art

[0002] The eccentric vibrating sand shaker is a type of vibrating sand shakeout equipment. When the motor drives the eccentric shaft to rotate through the conveyor belt, the sand shaker frame vibrates, and the castings placed on the grid are continuously thrown up, and then fall down by their own weight and collide with the grid, thereby breaking the castings. The molding sand falls through the grid holes and is transported away. The sand box and castings are sent out separately by transportation equipment.

[0003] In order to improve the working environment of the sand shaker, there is a prior art patent for a sand shaker with a dust reduction mechanism, for example, which is disclosed in China with the announcement number CN221434919U. The purpose of dust reduction is achieved by arranging dust covers, sealing covers, exhaust fans, dust collection bags and other components on the upper ports of the sand shaker frame. However, the patent has the disadvantage that the structure is relatively complex, and both the production of the structure and subsequent maintenance are time-consuming and labor-intensive, which will increase production costs.

The frame is a U-shaped structure. The frame is arranged on the base through a spring. The power mechanism is arranged on the base and the execution end is abutted against the lower end of the frame. The grid is arranged in the frame. The sand-falling machine also includes a dust-proof component arranged at the upper end of the frame. The dust-proof component includes a dust-proof cloth. One end of the dust-proof cloth is movably connected to the front end of the frame, and the other end is detachably connected to the rear end of the frame to cover the upper port of the frame.

[0006] Preferably, the dustproof component also includes a rotating shaft and a fixing bar; a mounting groove is opened at the front end of the frame; the rotating shaft is rotatably arranged in the mounting groove; one end of the dustproof cloth is fixed to the outer periphery of the rotating shaft, and the other end is fixed to the fixing bar; the fixing bar is detachably connected to the rear end of the frame.

[0007] Preferably, a slot is provided at the rear end of the frame; when in use, the fixing bar is at least partially embedded in the slot.

[0008] Preferably, the fixing strip is fixed to the rear end of the frame by screws.

[0009] Preferably, the rear ends of the fixing bar and the frame are both provided with magnetic strips for magnetic attraction.

[0010] Preferably, the size of the dustproof cloth is not smaller than the size of the upper port of the frame.

[0011] Preferably, the dustproof component further includes a handle; the handle is arranged on the outside of the frame and fixedly connected to the rotating shaft.

[0020] The following describes the specific embodiments of the present invention in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, not limiting, of the scope of the present invention.

[0021] See Figure 1-3In one embodiment of the present invention, a new type of sand-falling machine for separating castings includes: a base 1, a power mechanism, a plurality of springs 3, a frame 4, a grid 5, a dust-proof component 6 and a collecting hopper 7. The frame 4 body is in a U-shaped structure, and the frame 4 is arranged on the upper side of the base 1 through the spring 3. The power mechanism includes a motor 2 and an eccentric wheel. The motor 2 is mounted on the base 1 and the lower side of the frame 4. The eccentric wheel is mounted on the output shaft of the motor 2, and the eccentric wheel is abutted against the lower end of the frame 4; the grid 5 is mounted on the inner side of the frame 4; the collecting hopper 7 is mounted at the lower end of the frame 4, and the collecting hopper 7 and the frame 4 form a feeding channel. In addition, the collecting hopper 7 is a structure that is wide at the top and narrow at the bottom. The gradually closing design can effectively collect materials and reduce dust; the dust-proof component 6 is mounted at the upper end of the frame 4 to achieve the purpose of dust reduction. Through these arrangements, the sand-falling machine has the advantages of simple structure, easy operation, and easy later maintenance.

[0022] Specifically, a mounting groove 41 is provided at the front end of the upper end portion of the frame 4 , and an upwardly opening slot 42 is provided at the rear end portion of the upper end portion. It can be understood that the mounting groove 41 is located on the opposite side of the slot 42 .

[0023] The dustproof assembly 6 includes a rotating shaft 61, a dustproof cloth 62, a fixing strip 63 and a handle 64. The rotating shaft 61 is movably mounted in the mounting groove 41. The handle 64 is arranged on the outside of the frame 4 and is fixedly connected to one end of the rotating shaft 61. When the handle 64 is rotated by an external force, the rotating shaft 61 can rotate synchronously; one end of the dustproof cloth 62 is fixedly connected to the outer periphery of the rotating shaft 61, and the other end of the dustproof cloth 62 is fixedly connected to the fixing strip 63. The width of the dustproof cloth 62 is not greater than the length of the rotating shaft 61. In the initial state, the dustproof cloth 62 is rolled up on the rotating shaft 61, and the dustproof cloth 62 can be laid on the upper end of the frame 4 by pulling the fixing strip 63. In order for the dustproof cloth 62 to completely cover the upper end of the frame 4, the size of the dustproof cloth 62 should not be less than the size of the upper end of the frame 4; in this embodiment, the size of the fixing strip 63 is adapted to the size of the slot. When dust reduction is required, after the dustproof cloth 62 is spread out, the fixing strip 63 is at least partially embedded in or inserted into the slot, so that the dustproof cloth 62 remains in the spread-out state.

[0024] In one embodiment, the fixing connection method between the fixing strip 63 and the frame 4 is not limited to the above-mentioned plug-in fixing method, and can also be fixed by screw fixing or magnetic attraction.

[0025] In one embodiment, the fixing strip 63 is made of soft rubber.

[0026] In one embodiment, the dustproof cloth 62 plays the role of preventing dust and protecting articles, and needs to have good dustproof effect and strong durability. Therefore, the dustproof cloth 62 can be made of materials such as polyester and nylon.

[0027] Through this technical solution, by arranging a dust-proof cloth that can be rolled up and spread out at the upper end of the frame, the sand-falling machine has the advantages of simple structure, easy operation, and convenient later maintenance. It can not only achieve dust reduction, but also simplify the structure of the sand-falling machine to facilitate later maintenance and reduce production costs.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
