[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To address the technical problems of material accumulation and blockage during crushing and feeding, and low feeding efficiency, such as... Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:

[0025] A sand casting waste sand processing device includes a working frame 1 and a feeding seat 2 fixed above one side of the working frame 1. A power motor 3 is installed on one side of the feeding seat 2 and is fixed to the working frame 1. The output end of the power motor 3 is rotatably connected to a crushing roller 4, which is rotatably installed inside the feeding seat 2. The power motor 3 can drive the crushing roller 4 to rotate inside the feeding seat 2, thus forming a crushing structure based on existing principles. A discharge cylinder 5 is connected to the bottom of the feeding seat 2. A screening plate 6 is installed in the middle of the surface of the working frame 1, and a screen plate 6 is installed in the middle of the surface of the screen plate 6. With a sieve plate 7, a feeding plate 10 is fixed on one side below the working frame 1. A collection box 20 and a collection box 40 are arranged in sequence at the bottom of the working frame 1. The old sand to be processed is added into the feeding seat 2. After being crushed by the crushing roller 4, it will slide into the screening plate 6 through the feeding cylinder 5. After being screened by the sieve plate 7, the smaller particles will fall from the sieve plate 7 and be collected in the collection box 20, while the larger particles will fall from the rightmost end of the sieve plate 7 into the collection box 40. This completes the crushing and screening of the old sand, so that it can be reused.

[0026] The output end of the power motor 3 is fitted with a second belt 30, and a rotating wheel 8 is fitted below the second belt 30. The rotating wheel 8 is rotatably mounted on the working frame 1. The power motor 3 can synchronously drive the rotating wheel 8 to rotate together using the second belt 30. A toggle mechanism 9 is provided on one side of the rotating wheel 8. When the rotating wheel 8 rotates, it can eventually drive the toggle mechanism 9 to rotate in the feeding cylinder 5. When the toggle mechanism 9 rotates, it can agitate the crushed material in the feeding cylinder 5, which helps to accelerate the falling of the crushed material and avoid the possibility of accumulation and blockage in the feeding cylinder 5.

[0027] The rotating wheel 8 includes a slider 81 that is slidably disposed on the work frame 1, and the slider 81 is provided with a groove 84 on the outside of the groove 84. The slider 81 is fixedly connected to the side of the sieve plate 7. The sieve plate 7 and the slider 81 can slide left and right on the work frame 1 using the groove 84.

[0028] A rotating connecting rod 82 is rotatably mounted on one side of the slider 81, and a fixed arm 83 is rotatably mounted on one end of the rotating connecting rod 82. The fixed arm 83 is fixed to the rotating wheel 8 and can rotate together with the rotating wheel 8. When the fixed arm 83 rotates, the rotating connecting rod 82 pulls the slider 81 to move back and forth on the slide groove 84, thereby allowing the sieve plate 7 and the screening plate 6 to move back and forth on the working frame 1. By using the reciprocating movement of the sieve plate 7 and the screening plate 6, the material falling onto the screening plate 6 can be screened. The movement range of the mesh of the screening plate 6 is always within the first collection box 20, preventing the screened material from falling into the second collection box 40. At the same time, the screening power of the sieve plate 7 and the screening plate 6 is synchronously derived from the power motor 3, which can ensure the synchronicity of the processing and reduce the use of external power equipment.

[0029] A connecting shaft 85 is fixed to the middle of one side of the rotating wheel 8, and the connecting shaft 85 is rotatably mounted on the work frame 1. The connecting shaft 85 can rotate synchronously with the rotating wheel 8. The actuating mechanism 9 includes a rotating wheel 91 fixed to one end of the connecting shaft 85, and a belt 92 is sleeved on the outside of the rotating wheel 91. A rotating wheel 93 is provided above one end of the belt 92, and the rotating wheel 91 is connected to the rotating wheel 93 through the belt 92.

[0030] A connecting shaft 94 is fixed to one side of the second rotating wheel 93, and the connecting shaft 94 is rotatably installed inside the feeding cylinder 5. A lever 95 is fixed to the outer surface of the connecting shaft 94. When the connecting shaft 85 rotates, the rotational power is transmitted through the first rotating wheel 91, the first belt 92 and the second rotating wheel 93 to drive the connecting shaft 94 and the lever 95 to rotate counterclockwise inside the feeding cylinder 5. When the lever 95 rotates, it can move the crushed material inside the feeding cylinder 5, which helps to accelerate the falling of the crushed material and avoid the possibility of material accumulating and blocking inside the feeding cylinder 5. This helps to improve the processing effect of the device and reduce the trouble of manual shutdown for unblocking. At the same time, the power of the connecting shaft 94 and the lever 95 also comes from the power motor 3, which can further reduce the consumption of external power equipment.

[0031] To address the technical problems of poor separation efficiency, incomplete screening, and high energy consumption due to dispersed power sources in the equipment, such as... Figure 1 - Figure 5 As shown, the following preferred technical solutions are provided:

[0032] The sieve plate 7 includes a support plate 71 fixed to the bottom of the screening plate 6, and a connecting spring 72 fixed above the support plate 71. The top of the connecting spring 72 is fixed to the bottom of the sieve plate 7, and the sieve plate 7 is elastically connected to the support plate 71 through the connecting spring 72. The sieve plate 7 and the screening plate 6 are slidably connected, and the outer edge of the sieve plate 7 is in contact with the inner wall of the screening plate 6, so that the screening plate 6 can move elastically up and down on the sieve plate 7.

[0033] A fixing plate 73 is provided at the bottom of the sieve plate 7, and the fixing plate 73 is fixed on the working frame 1. An arc-shaped protrusion 74 is fixed at the top of the fixing plate 73, and an arc-shaped protrusion 75 is fixed on the bottom surface of the sieve plate 7. When the sieve plate 7 moves back and forth with the screening plate 6, the arc-shaped protrusion 75 at the bottom of the sieve plate 7 will continuously pass over the arc-shaped protrusion 74, so that the arc-shaped protrusion 75 will continuously squeeze and push the sieve plate 7 upward. At the same time, under the action of gravity, the connecting spring 72 and the sieve plate 7 fall, so that the sieve plate 7 has a vibration effect when moving and screening, which is beneficial to improving the screening effect of the sieve plate 7 and thus improving the processing effect of the device. At the same time, the vibration of the sieve plate 7 is automatically achieved when the sieve plate 7 moves, which can improve efficiency and reduce the consumption of external power equipment.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
