[0004] The purpose of this invention is to provide a mechanical sand particle separation and screening device, which solves the problems that the device is not easy to adjust the feed speed, which affects the screening efficiency, and that the particles screened by the device are not easy to be diverted and discharged from the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a machined sand particle separation and screening device, comprising a support cylinder, a cylinder body fixedly connected to the upper end of the support cylinder, a guide cover fixedly connected to the upper end of the cylinder body, a feeding mechanism provided on the guide cover, a screening mechanism provided inside the cylinder body, a material trough fixedly connected to the surface of the cylinder body, a guide plate fixedly connected inside the support cylinder, and an extension plate of the guide plate penetrating through the support cylinder and fixedly connected to the support cylinder.

[0006] The feeding mechanism includes a feeding cylinder, with the feeding cylinder fixedly connected to the lower end of the guide cover. A plug is slidably connected inside the feeding cylinder, and a baffle is fixedly connected to the lower end of the feeding cylinder. A sliding pin is fixedly connected to the surface of the plug, and the sliding pin is slidably connected to the feeding cylinder. By rotating the screw ring and the feeding cylinder to make a threaded movement, the sliding pin drives the plug to slide inside the feeding cylinder, thereby making it easy to control the discharge speed of the feeding cylinder and avoiding excessive feeding speed from affecting the screening effect.

[0007] Preferably, a retaining sleeve is fixedly connected to the outer side of the sliding pin, and the retaining sleeve is slidably connected to the feed cylinder. By setting the retaining sleeve, the feed cylinder is sealed off.

[0008] Preferably, a threaded ring is connected to the outer side of the feed cylinder, and the threaded ring and the sliding pin are slidably connected. The movement of the sliding pin is controlled by the threaded ring.

A square cylinder is slidably connected to the outer side of the square rod. The square cylinder and the filter cover are fixedly connected. An inclined block is fixedly connected to the lower end of the filter cover.

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

[0013] 1. This utility model uses the rotating screw ring and the feed cylinder to make a spiral motion, which causes the sliding pin to drive the plug to slide inside the feed cylinder, thereby making the discharge speed of the feed cylinder easy to control and avoiding the feeding speed being too fast and affecting the screening effect.

[0014] 2. This utility model uses a motor to drive the filter cover to rotate, which in turn causes the filter cylinder to rotate synchronously and perform centrifugal motion, thereby making sand screening more efficient.

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, those skilled in the art who have not made any innovative embodiments are all within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 4 A manufactured sand particle separation and screening device includes a support cylinder 1, a cylinder body 2 fixedly connected to the upper end of the support cylinder 1, a guide cover 3 fixedly connected to the upper end of the cylinder body 2, a feeding mechanism 4 provided on the guide cover 3, a screening mechanism 5 provided inside the cylinder body 2, a material trough 6 fixedly connected to the surface of the cylinder body 2, a guide plate 7 fixedly connected inside the support cylinder 1, and an extension plate of the guide plate 7 penetrating through the support cylinder 1 and fixedly connected to the support cylinder 1.

[0022] Please see Figure 1 , Figure 2 , Figure 3 The feeding mechanism 4 includes a feeding cylinder 41. The lower end of the guide cover 3 is fixedly connected to the feeding cylinder 41. A plug 42 is slidably connected inside the feeding cylinder 41. A baffle 43 is fixedly connected to the lower end of the feeding cylinder 41. A sliding pin 44 is fixedly connected to the surface of the plug 42. The sliding pin 44 and the feeding cylinder 41 are slidably connected. A retaining sleeve 45 is fixedly connected to the outside of the sliding pin 44. The retaining sleeve 45 and the feeding cylinder 41 are slidably connected. By setting the retaining sleeve 45, the feeding cylinder 41 is closed. A screw ring 46 is threadedly connected to the outside of the feeding cylinder 41. The screw ring 46 and the sliding pin 44 are slidably connected. By setting the screw ring 46, the movement of the sliding pin 44 is controlled. By rotating the screw ring 46 and the feeding cylinder 41 to make threaded movement, the sliding pin 44 drives the plug 42 to slide inside the feeding cylinder 41. This makes it easier to control the discharge speed of the feeding cylinder 41 and avoids the feeding speed being too fast, which would affect the screening effect.

[0023] Please see Figure 4 The screening mechanism 5 includes a filter cylinder 51. The filter cylinder 51 is mounted inside the cylinder 2 via bearings. A filter cover 52 is slidably connected inside the filter cylinder 51. A guide bar 53 is fixedly connected inside the filter cylinder 51, and the guide bar 53 and the filter cover 52 are slidably connected. By setting the guide bar 53, relative rotation between the filter cylinder 51 and the filter cover 52 is prevented. A support ring 54 is fixedly connected inside the support cylinder 1. A motor 55 is fixedly mounted at the lower center of the support ring 54. The rotating shaft of the motor 55 passes through the support ring 54 and is rotatably connected to it. A square rod 56 is fixedly connected to the upper end of the rotating shaft of the motor 55. The outer side of the square rod 56 is slidably connected to... A square tube 57 is connected to a filter cover 52. An inclined block 58 is fixedly connected to the lower end of the filter cover 52. A stop block 59 is fixedly connected inside the support cylinder 1. The stop block 59 and the inclined block 58 are slidably connected. By setting the stop block 59, the inclined block 58 can be moved easily. The filter cover 52 is driven to rotate by the motor 55, which in turn causes the filter cylinder 51 to rotate synchronously and perform centrifugal motion, thereby making the sand screening more efficient. At the same time, the collision between the inclined block 58 and the stop block 59 causes the filter cover 52 to slide inside the filter cylinder 51, which makes it easier for large particles screened on the filter cover 52 to enter the guide groove of the cylinder 2 and be discharged.

[0024] The specific implementation process of this utility model is as follows: In use, the device is adjusted according to the screening efficiency requirements. The screw 146 is manually rotated, the screw ring 46 rotates and the feed cylinder 41 makes a spiral movement, which causes the sliding pin 44 to drive the plug 42 to slide in the feed cylinder 41, thus making it easier to control the discharge speed of the feed cylinder 41 and avoid the feeding speed being too fast and affecting the screening effect. Then, the motor 55 is started, and the motor 55 drives the filter cover 52 to rotate. The filter cover 52 drives the filter cylinder 51 to rotate. Through the motor 55 driving the filter cover 52 to rotate, the filter cylinder 51 rotates synchronously to make centrifugal motion, thus making the sand screening more efficient. The rotation of the filter cover 52 drives the inclined block 58 to move, so that the inclined block 58 collides with the stop block 59, thus causing the inclined block 58 to move upward. The inclined block 58 drives the filter cover 52 to move upward, thus causing the filter cover 52 to slide in the filter cylinder 51, thus making it easier for the large particles screened on the filter cover 52 to enter the guide groove of the cylinder 2 for discharge.
