Description

Technical Field

[0001] This application relates to the field of coated sand cooling bed technology, and in particular to a coated sand cooling bed that is easy to adjust. Background Art

[0002] Coated sand is a special casting sand, also known as coated casting sand. Different from traditional casting sand, it is a casting sand formed by coating a thin film on the surface of the mold before casting and drying. Coated sand mainly consists of three parts: sand grains, binders, and thin films. The temperature of the freshly produced coated sand is very high. In the prior art, it is mostly cooled naturally or by blowing air through a lifting conveyor. During cooling, the coated sand being conveyed is not cooled comprehensively enough, and due to the action of the binder, the produced coated sand may be partially adhered, resulting in a reduction in quality, etc.

[0003] Existing coated sand cooling beds improve the cooling efficiency of coated sand by assembling a sand turning mechanism. However, the sand turning mechanism generally has a limited effect on reducing the adhesion of the coated sand, thereby causing a decline in the production quality of the coated sand.

[0004] In view of the above related technologies, the inventor believes that the existing coated sand cooling beds have the problem of being unable to effectively solve the problem of partial adhesion of coated sand, resulting in a reduction in the quality of coated sand. Summary of the Utility Model

[0005] In order to solve the problem that the existing coated sand cooling beds cannot effectively solve the problem of partial adhesion of coated sand, resulting in a reduction in the quality of coated sand, this application provides a coated sand cooling bed that is easy to adjust.

[0006] A coated sand cooling bed that is easy to adjust provided by this application adopts the following technical solutions:

[0007] A coated sand cooling bed that is easy to adjust includes a cooling bed, a moving mechanism connected to the cooling bed, a feeding mechanism disposed above the cooling bed, and a sand turning mechanism connected to the cooling bed; the feeding mechanism includes a mounting frame, a feeding box connected to the mounting frame, a group of crushing rollers disposed in the feeding box, and a first driving component for driving the crushing rollers to rotate. The crushing rollers are rotatably connected to the feeding box. The number of a group of the crushing rollers is two. A feeding port is opened on one side of the feeding box away from the cooling bed, and a discharge port is opened on one side close to the cooling bed; the moving mechanism includes a first support rod connected to the cooling bed. One end of the first support rod away from the cooling bed is connected to a bottom plate, and a universal wheel is connected to one side of the bottom plate away from the first support rod.

[0008] By adopting the above technical solution, the coated sand enters the feed box through the feed inlet. The first driving component drives the crushing roller to rotate, and the crushing roller disperses the agglomerated coated sand. The dispersed coated sand falls onto the cooling bed through the discharge outlet, pushing the cooling bed to move, so that the coated sand is evenly distributed on the cooling bed. Then, the coated sand is turned over by the sand turning mechanism, thereby improving the cooling efficiency of the coated sand. Through the dispersion of the coated sand by the crushing roller, the phenomenon of adhesion and agglomeration of the coated sand is reduced, thereby improving the production quality of the coated sand.

[0009] Optionally, the number of the crushing rollers is multiple groups, and the multiple crushing rollers are arranged staggeredly.

[0010] By adopting the above technical solution, the multiple groups of staggeredly arranged crushing rollers increase the dispersion effect on the coated sand, thereby further reducing the phenomenon of adhesion and agglomeration of the coated sand, and further improving the production quality of the coated sand.

[0011] Optionally, a plurality of crushing teeth are arranged on the surface of the crushing roller, and the crushing teeth are evenly distributed.

[0012] By adopting the above technical solution, the arrangement of the crushing teeth improves the dispersion effect on the coated sand, thereby further reducing the phenomenon of adhesion and agglomeration of the coated sand, and further improving the production quality of the coated sand.

[0013] Optionally, the crushing teeth on the adjacent crushing rollers are arranged staggeredly, and the gaps between the crushing teeth on the adjacent crushing rollers form a channel for the coated sand to fall.

[0014] By adopting the above technical solution, the staggeredly arranged crushing teeth enable the coated sand to fall through the narrow gaps, further increasing the dispersion effect on the coated sand, thereby improving the production quality of the coated sand.

[0015] Optionally, the first driving component includes a first driving motor fixedly connected to the feed box. A first gear is fixedly connected to the transmission shaft of the first driving motor. A second gear is fixedly connected to the crushing roller. The first gear is meshed with the second gear, and the first driving motor drives two vertically adjacent crushing rollers to rotate.

[0016] By adopting the above technical solution, the first driving motor drives the first gear to rotate, and the first gear drives the second gear to rotate, thereby driving the vertically adjacent crushing rollers to rotate.

[0017] Optionally, a screw conveyor is connected to one side of the feed box away from the cooling bed, and the screw conveyor is communicated with the feed box through the feed inlet.

[0018] By adopting the above technical solution, the spiral feeder makes the feeding process uniform and stable, reduces the phenomenon of the coated sand accumulating in the feeding box, and thus improves the dispersion efficiency of the coated sand.

[0019] Optionally, the sand turning mechanism includes a second driving component arranged on the cooling bed, a connecting plate connected to the second driving component, and a plurality of sand scraping bars arranged on the connecting plate; a sliding groove is formed on the side wall of the cooling bed, and the second driving component includes a second driving motor arranged on the cooling bed, a reciprocating lead screw and a slider arranged in the sliding groove. One end of the reciprocating lead screw is fixedly connected to the transmission shaft of the second driving motor, and the other end is rotatably connected to the cooling bed. The slider is slidably connected to the sliding groove and is threadedly connected to the reciprocating lead screw, and the slider is connected to the connecting plate.

[0020] By adopting the above technical solution, the second driving motor drives the reciprocating lead screw to rotate, the reciprocating lead screw drives the slider to slide in the sliding groove, the slider drives the connecting plate to reciprocate, and the connecting plate drives the sand scraping bars to turn the coated sand, thereby improving the cooling efficiency of the coated sand.

[0021] Optionally, the slider is connected with a first electric telescopic rod, and one end of the first electric telescopic rod far away from the slider is connected to the connecting plate.

[0022] By adopting the above technical solution, the first electric telescopic rod drives the connecting plate and the sand scraping bars to move, so that the sand scraping bars turn the coated sand at different positions, thereby further improving the cooling efficiency of the coated sand.

[0023] Optionally, a second electric telescopic rod is arranged on the connecting plate, a scraping plate is connected to the telescopic end of the second electric telescopic rod, and the height of the scraping plate is less than the height of the sand scraping bars.

[0024] By adopting the above technical solution, when the coated sand needs to be bagged after cooling, the second electric telescopic rod drives the scraping plate to move towards the coated sand, and the slider drives the connecting plate and the scraping plate to move, so that the scraping plate gathers the coated sand scattered on the cooling bed, thereby facilitating the bagging of the coated sand.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The first driving motor drives the crushing roller to rotate, and the crushing roller disperses the coated sand through the crushing teeth, and at the same time pushes the cooling bed, so that the coated sand falling from the feeding box evenly falls on the cooling bed, thereby reducing the phenomenon of the coated sand sticking and agglomerating and improving the production quality of the coated sand;

[0027] 2. The setting of the first electric telescopic rod increases the sand turning effect on the coated sand, thereby improving the cooling efficiency of the coated sand;

[0028] 3. By setting the scraping plate, the coated sand is gathered together after being cooled, thus improving the bagging efficiency of the coated sand. BRIEF DESCRIPTION OF THE DRAWINGS
