Since the molding materials used in sand casting are cheap and easy to obtain, and the mold manufacturing is simple, it can adapt to single-piece production, batch production and mass production of castings.

[0003] However, a large amount of waste sand will be generated in sand casting production. These waste sands are prone to form large lumps due to high temperature and mixing with metal impurities. At present, the general method for cleaning waste sand is to cut and crush it and then reuse it. However, the crushed waste sand still contains a large amount of impurities. If these impurities are not cleaned and filtered, it will cause the mixing of impurities in the castings produced later, thus reducing the quality of the products. Content of the Utility Model

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. For this waste sand cleaning device for oil pump castings, by setting the first gear, the second gear, the crushing teeth, the mounting frame and the sieve box, when the motor rotates to drive the first gear, due to the meshing of the first gear and the second gear, the two rotating rods rotate, so that the crushing teeth can cut and crush the filled waste sand, facilitating subsequent screening and filtering. The crushed waste sand will fall into the first sieve box. At this time, the vibration motor will continuously push the mounting frame, causing the mounting frame to vibrate continuously, so that the sieve box mounted on the mounting frame can screen out the impurities in the waste sand. The preliminarily screened waste sand will fall into the second sieve box for secondary screening, thus cleaning and filtering out the impurities in the waste sand, greatly reducing the amount of residual impurities in the waste sand.

Specific embodiments

[0020] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, the present utility model provides a technical solution: an oil pump casting waste sand cleaning device, including a body 1, a collection box 2 is slidably installed below the interior of the body 1, a second handle 28 is connected in front of the collection box 2, and anti-slip rubber layers are provided on both the first handle 27 and the second handle 28. The waste sand after multiple filtrations will fall into the collection box 2, so as to centrally collect the cleaned waste sand, and the anti-slip rubber layers on the first handle 27 and the second handle 28 can increase the friction force, thereby avoiding accidental slipping and falling when taking the collection box 2 and the sieve box 20.

[0022] A fixing plate 3 is connected inside the body 1, a filler hopper 4 is connected above the body 1, a guiding plate 5 is connected to the inner wall of the filler hopper 4, a mounting plate 6 is connected to one side of the filler hopper 4, a rotating motor 7 is installed on the mounting plate 6, the output shaft of the rotating motor 7 is connected to a first gear 8, the first gear 8 is meshed and connected to a second gear 9, the centers of the first gear 8 and the second gear 9 are connected to a rotating rod 10, the rotating rod 10 is rotatably installed inside the filler hopper 4, the guiding plate 5 is inclined towards the center of the filler hopper 4, and the fixing rod 23 is inserted into the fixing hole 17. Through the meshing of the first gear 8 and the second gear 9, the crushing teeth 11 on the two rotating rods 10 can rotate in opposite directions, so as to swallow and crush the filled waste sand, reducing the volume of the waste sand for subsequent filtration and cleaning.

[0023] A crushing tooth 11 is installed on the rotating rod 10, and a slide groove 12 is opened on both sides of the fixed plate 3. A vibration motor 13 is installed on the fixed plate 3. The output end of the vibration motor 13 is connected to a mounting frame 14, and sliders 18 are connected to both sides of the mounting frame 14. A smooth rod 15 is connected inside the slide groove 12, and first springs 19 are sleeved on both ends of the smooth rod 15. The slider 18 is slidably connected to the smooth rod 15, one end of the first spring 19 is connected to the inner wall of the fixed plate 3, and the other end of the first spring 19 is connected to the slider 18. Through the sliding of the slider 18 on the smooth rod 15, the mounting frame 14 can move smoothly along the smooth rod 15, and the vibration is buffered to a certain extent by compressing the first spring 19 during movement, so as to avoid excessive vibration causing the mounting frame 14 to collide with the fixed plate 3 and cause damage.

[0024] Connecting grooves 16 are provided on both sides of the inner wall of the mounting frame 14, and a screen box 20 is slidably installed on the mounting frame 14 through the connecting grooves 16. Connecting strips 25 are connected to both sides of the screen box 20, and a screen hole 26 is provided at the bottom of the screen box 20. A first handle 27 is connected to the front of the screen box 20, and the connecting strip 25 slides in the connecting groove 16. Through the sliding of the connecting strip 25 in the connecting groove 16, the staff can quickly and conveniently complete the installation and positioning of the screen box 20, thereby improving the speed of installation and disassembly.

[0025] There are two screen boxes 20, which are distributed up and down inside the machine body 1 through the mounting frame 14 respectively, and the screen holes 26 opened at the bottom of the lower screen box 20 are smaller in diameter than the screen holes 26 opened at the bottom of the upper screen box 20. Fixing holes 17 are opened on both sides above the mounting frame 14, and connecting rods 21 are connected to both sides above the screen box 20. The connecting rods 21 are slidably connected to the sliding plate 22, and the sliding plate 22 is connected to a fixing rod 23 below the sliding plate 22. The second spring 24 is connected below the sliding plate 22. The impurities in the waste sand are filtered and cleaned multiple times through the screen boxes 20 with two screen holes 26 with gradually smaller apertures, thereby improving the filtering effect of impurities and ensuring the quality of subsequent castings.

[0026] The working principle of the utility model is:

[0027] The sieve box 20 is installed on the mounting frame 14 by pushing the connecting bar 25 into the connecting groove 16. Then, the sliding plate 22 is pulled to stretch the second spring 24. Next, the fixing rod 23 is aligned with the fixing hole 17, and at the same time, the sliding plate 22 is released, so that the second spring 24 rebounds to pull the sliding plate 22, causing the fixing rod 23 to be inserted into the fixing hole 17, thereby fixing the sieve box 20 on the mounting frame 14. The rotation motor 7 is started to rotate the first gear 8, and through the meshing of the first gear 8 and the second gear 9, the two rotating rods 10 can rotate synchronously, so that the crushing teeth 11 can cut and crush the filled waste sand. The crushed waste sand will fall into the first sieve box 20. At this time, the vibration motor 13 will continuously push the mounting frame 14, causing the mounting frame 14 to vibrate continuously, so that the first sieve box 20 can initially screen out the impurities in the waste sand. The waste sand after the initial screening will fall into the second sieve box 20 for secondary screening, so as to clean and filter out the impurities in the waste sand. The waste sand after multiple filtrations will finally fall into the collection box 2 for centralized collection and treatment.
