Description

Technical Field

[0001] This utility model relates to the field of sand removal machine technology, and in particular to a single-mass vibration sand removal machine. Background Technology

[0002] In the casting production process, the vibratory sand shaker is the core equipment for separating castings from sand molds, and its working efficiency directly affects production efficiency and the quality of molding sand recovery.

[0003] When the castings enter the sand removal grid, the material exhibits regular directional movement under the action of inertial force due to the unidirectional excitation force generated by the single-mass vibration system. This single-dimensional vibration mode makes it difficult for the molding sand and castings to achieve effective stratification. Especially when processing irregularly shaped castings or large-mass workpieces, it is easy to form a material accumulation phenomenon in the central area, forming a local high-density area, which seriously restricts the effective transmission of vibration energy and results in poor sand removal effect. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a single-mass vibrating sand removal machine to solve the current problem of material accumulation in the central area, forming a local high-density area, which seriously restricts the effective transmission of vibration energy and leads to poor sand removal effect.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A single-mass vibrating sand removal machine includes a base frame, a sand removal chamber and two sets of springs. A perforated plate is welded to the lower part of the sand removal chamber, and a perforated frame is welded to the inside of the sand removal chamber and above the perforated plate.

[0008] Both sides of the sand drop chamber are equipped with rotary drive sources. The top of the rotating end of the rotary drive source is fixedly connected to a flat material plate, and both sides of the sand drop chamber are provided with movable channels for the flat material plate to pass through.

[0009] The rotary drive source includes a bearing plate, a protrusion welded to the center of the bearing plate facing outwards, a rotating shaft rotatably mounted on the top of the protrusion via a bearing, and a flat plate fixed on the top of the rotating shaft. A drive body is mounted on both sides of the top of the bearing plate, and a rack is fixedly connected between the movable ends of the two drive bodies. A gear that meshes with the rack is fixed at one end of the rotating shaft.

[0010] As an improved technical solution, the rotary drive source also includes a linear motor fixed to the side of the sand-falling chamber by a bracket, and a supporting cross plate is installed on the movable end of the linear motor.

[0011] As an improved technical solution, the driving body includes a driving motor installed on the top of the supporting cross plate, the driving end of the driving motor is fixedly connected to a winding disc, and a steel wire rope is installed inside the winding cavity of the winding disc.

[0012] As an improved technical solution, a linkage block is welded to the middle of the end face of the rack away from the rotation axis, and the linkage block is fixed between the steel wire ropes on the two drive bodies.

[0013] As an improved technical solution, a guide rail is fixed at the top of the bearing plate and between the linear motors on both sides, and a slider that slides on the guide rail is installed at the bottom of the linkage block.

[0014] As an improved technical solution, the two sets of springs are respectively installed on both sides of the top of the base frame, the sand drop chamber is installed on the top of the base frame by the two sets of springs, and a vibration motor is installed on both sides of the sand drop chamber.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, two drive bodies retract and unwind the rack, causing it to move laterally in a reciprocating motion. Under the meshing transmission of the rack and gear, the flat plate swings with the rotating shaft. During the movement of the flat plate, it comes into contact with the casting material accumulated inside the sand-falling bin and pushes the casting material accumulated on the upper layer to the side, preventing the casting material from accumulating in the middle of the sand-falling bin. This helps to distribute the casting material more evenly inside the sand-falling bin. The casting material spread evenly inside the sand-falling bin can effectively receive vibration energy and improve its sand-falling effect.

[0017] 2. In this utility model, during the rotation of the flat plate driven by two drive motors, the bearing plate is moved laterally by a linear motor, which causes the flat plate to adjust its lateral position inside the sand drop chamber. This helps to expand the rotation area of ​​the flat plate inside the sand drop chamber and promotes the flat plate to spread the casting material more evenly inside the sand drop chamber.

[0028] like Figures 1 to 3 As shown in the figure, this embodiment provides a single-mass vibrating sand removal machine, which includes a base frame 1, a sand removal chamber 2 and two sets of springs 3. A perforated plate 8 is welded to the lower part of the sand removal chamber 2, and a perforated frame 7 is welded to the inside of the sand removal chamber 2 and above the perforated plate 8.

[0029] Rotary drive sources 5 are installed on both sides of the sand drop bin 2. A flat material plate 6 is fixedly connected to the top of the rotating end of the rotary drive source 5, and movable channels 9 for the flat material plate 6 to pass through are opened on both sides of the sand drop bin 2.

[0030] The rotary drive source 5 includes a bearing plate 52. A protrusion 53 is welded to the middle of the outer side of the bearing plate 52. A rotating shaft 54 ​​is rotatably mounted on the top of the protrusion 53 via a bearing. A flat plate 6 is fixed on the top of the rotating shaft 54. A drive body 55 is mounted on both sides of the top of the bearing plate 52. A rack 57 is fixedly connected between the movable ends of the two drive bodies 55. A gear 56 that meshes with the rack 57 is fixed to one end of the rotating shaft 54.

[0031] like Figures 1 to 2 As shown in the figure, in this embodiment, the rotary drive source 5 also includes a linear motor 51 fixed to the side of the sand drop chamber 2 by a bracket, and the bearing plate 52 is installed on the movable end of the linear motor 51. During the process of the two drive motors 551 driving the flat plate 6 to rotate, the linear motor 51 drives the bearing plate 52 to move laterally, thereby adjusting the lateral position of the flat plate 6 inside the sand drop chamber 2. This helps to expand the rotation area of ​​the flat plate 6 inside the sand drop chamber 2 and promotes the flat plate 6 to spread the casting material more evenly inside the sand drop chamber 2.

[0032] like Figure 2 As shown, in this embodiment, the driving body 55 includes a driving motor 551 mounted on the top of the bearing cross plate 52. The driving end of the driving motor 551 is fixedly connected to a winding disc 553, and a steel wire rope 552 is installed inside the winding cavity of the winding disc 553.

[0033] The two drive bodies 55 rotate and unwind, causing the rack 57 to move laterally in a reciprocating motion. Under the meshing transmission of the rack 57 and the gear 56, the rotating shaft 54 ​​is driven to rotate in the forward and reverse directions. The flat plate 6 swings with the rotation of the rotating shaft 54. During the movement of the flat plate 6, it will contact the casting material accumulated inside the sand drop chamber 2 and push the casting material accumulated on the upper layer to the side, avoiding the accumulation of casting material in the middle of the sand drop chamber 2. This helps to distribute the casting material more evenly inside the sand drop chamber 2. The casting material spread evenly inside the sand drop chamber 2 can effectively receive vibration energy and improve its sand drop effect.

[0034] like Figures 2 to 3 As shown in the figure, in this embodiment, a linkage block 59 is welded to the middle of the end face of the rack 57 away from the rotation axis 54, and the linkage block 59 is fixed between the steel wire ropes 552 on the two drive bodies 55.

[0035] like Figure 3 As shown, in this embodiment, a guide rail 58 is fixed at the top of the bearing plate 52 and between the two drive motors 551, and a slider 510 that slides on the guide rail 58 is installed at the bottom of the linkage block 59.

[0036] like Figure 1 As shown, in this embodiment, two sets of springs 3 are respectively installed on both sides of the top of the base frame 1, and the sand drop chamber 2 is installed on the top of the base frame 1 by two sets of springs 3. Vibration motors 4 are installed on both sides of the sand drop chamber 2.

[0037] In use, the casting material is fed into the sand drop chamber 2 by a forklift or other equipment and falls onto the orifice plate 7. The vibration motor 4 causes the sand drop chamber 2 to vibrate, causing the casting material to vibrate continuously, shaking off the sand on the casting material and passing through the orifice plate 8, and being discharged from the discharge port at the bottom of the sand drop chamber 2.

[0038] When the material is poured into the sand drop hopper 2, the drive body 55 on one side winds up the wire rope 552 on the other side and unwinds the wire rope 552 on the other side. This will move the rack 57 toward the drive body 55 in the winding state. Then, the two drive bodies 55 reverse the winding and unwinding, so that the rack 57 is in a lateral reciprocating motion state. Under the meshing transmission of the rack 57 and the gear 56, the drive shaft 54 ​​rotates in the forward and reverse directions. The flat plate 6 swings with the rotation shaft 54. During the movement of the flat plate 6, the flat plate 6 will contact the casting material piled up inside the sand drop hopper 2 and push the casting material piled up on the upper layer to the side, so as to avoid the casting material from accumulating in the middle of the sand drop hopper 2 and make it more evenly distributed inside the sand drop hopper 2.

[0039] During the rotation of the flat plate 6 driven by the two drive motors 551, the bearing plate 52 is driven by the linear motor 51 to move laterally, which causes the flat plate 6 to adjust its lateral position inside the sand drop chamber 2. This helps to expand the rotation area of ​​the flat plate 6 inside the sand drop chamber 2 and promotes the flat plate 6 to spread the casting material more evenly inside the sand drop chamber 2.

[0040] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
