Description

Technical Field

[0001] This utility model relates to the field of sand screening machine technology, specifically a rolling sand screening machine. Background Technology

[0002] A sand screening machine, also known as a dryland sand screening vessel or sand and gravel separator, is a sand and gravel separation device suitable for rivers, reservoirs, and coal yards. It consists of a hull, frame, reducer, conveyor belt, rotary screen, and engine or motor. This machine has a simple structure, is economical and practical, and easy to operate. It is available in various types, including drum-type sand screening machines, water-washed drum-type sand screening machines, and vibrating screen-type sand screening machines.

[0003] When screening sand and gravel, a rolling sand screening machine is generally used. However, due to the high water content of the sand and gravel, a large amount of fine sand adheres to the inner wall surface of the screening machine's drum screen during the screening process, causing the drum screen to become clogged and affecting the screening effect of the sand screening machine. To address this, we have proposed a rolling sand screening machine. Utility Model Content

[0004] The purpose of this invention is to provide a rolling sand screening machine to solve the problems existing in the background art.

[0022] 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.

[0023] Please see Figure 1-8 As shown, a rolling sand screening machine includes a sand screening machine body 1. A motor 2 is fixed to the rear surface of the sand screening machine body 1. The output shaft of the motor 2 is bolted with a transmission rod 16, and the other end of the transmission rod 16 passes through the sand screening cylinder and is fixedly connected to a linkage mechanism 17. A feed hopper 11 is fixedly connected to the top of the sand screening machine body 1, and a cover plate 4 is fixedly connected to the top of the feed hopper 11. Drying boxes 9 are fixedly connected to both sides of the surface of the sand screening machine body 1. Several fans 13 are installed inside the drying boxes 9, and heating wires 14 of the same number as the fans 13 are installed inside the drying boxes 9. A brush roller 3 is rotatably connected to the top of the sand screening machine body 1. One end of the brush roller 3 passes through the interior of the tripod on the top plate of the sand screening machine body 1 and is fixed to the interior of the other side of the linkage mechanism 17. A transmission mechanism 6 is installed on the surface of the other end of the brush roller 3. Sealing plates 8 are fixedly connected to the opposite side of the rear two fans 13. A connecting pipe 7 is connected to the surface of the sealing plate 8. The other end of the connecting pipe 7 passes through the feed hopper 11 and is connected to its interior.

[0024] The transmission mechanism 6 includes a first synchronous pulley 61, the interior of which is fixedly connected to the surface of the brush roller 3. The first synchronous pulley 61 is connected to the second synchronous pulley 62 via a synchronous belt. A stirring rod 63 is fixedly connected to the rear side of the second synchronous pulley 62. The other end of the stirring rod 63 passes through the interior of the feed hopper 11 and is rotatably connected to its inner wall. With the rotation of the brush roller 3, the first synchronous pulley 61 can be driven to rotate, and the second synchronous pulley 62 can be driven to rotate via the synchronous belt, thereby driving the stirring rod 63 to stir the sand and gravel inside the feed hopper 11.

[0025] A protective cover 5 is fixedly connected to the front side of the sand screening machine body 1. The first synchronous wheel 61 and the second synchronous wheel 62 are both set inside the protective cover 5. The protective cover 5 can prevent sand and gravel from spilling out and getting stuck in the synchronous belt during feeding, which would cause the synchronous belt to break and thus affect the work progress.

[0026] Several dustproof nets 10 are fixedly connected to the outside of the drying oven 9. The dustproof nets 10 are set outside the fan 13. By setting the dustproof nets 10, external dust and debris can be prevented from being sucked into the drying oven 9 by the fan 13, thereby avoiding clogging of the heating wire 14 or affecting airflow circulation, and at the same time protecting the fan 13 blades from wear.

[0027] The drying oven 9 is fixedly connected with several protective railings 12, and the protective railings 12 are set on the side where the heating wires 14 face each other. The protective railings 12 can prevent foreign objects thrown up when the sand screening drum rotates from entering the drying oven 9 and prevent the heating wires 14 from being damaged by collision.

[0028] A protective net 15 is installed inside the connecting pipe 7 at one end of the feed hopper 11, and the protective net 15 is located above the stirring rod 63. The protective net 15 can prevent sand or debris from entering the connecting pipe 7, thus avoiding pipe blockage and affecting the hot air delivery.

[0029] Working principle: When screening sand and gravel using the sand screening machine body 1, the sand and gravel are first poured into the feed hopper 11 at the top of the sand screening machine body 1. Then, the motor 2 of the sand screening machine body 1 is turned on. The motor 2 drives the transmission rod 16 to rotate, and through the linkage mechanism 17, it drives the brush roller 3 to rotate, so that the brush roller 3 can clean the surface of the sand screening drum. Since the rotation of the brush roller 3 drives the first synchronous pulley 61 to rotate, it drives the second synchronous pulley 62 to rotate through the synchronous belt, which in turn drives the stirring rod 63 to rotate. In this way, the sand and gravel in the feed hopper 11 can be stirred. At the same time, the heating wire 14 and the fan 13 are turned on. The heating wire 14 generates heat, raising the ambient air temperature. The fan 13 blows the hot air through the sealing plate 8, guiding it to the connecting pipe 7 and then into the feed hopper 11. This allows the hot air to contact the sand and gravel being stirred inside the feed hopper 11, preheating the sand and gravel and evaporating the moisture inside. The sand and gravel then fall into the drum of the sand screening machine body 1 for screening. Meanwhile, the hot air blown by the fan 13 dries the drum, preventing sand and gravel from adhering to the inner wall of the drum while the brush roller 3 cleans it.
