Description

Technical Field

[0001] The utility model relates to the technical field of machine-made sand production equipment, in particular to machine-made sand transfer equipment. Background Art

[0002] After artificial sand is made by professional equipment, it needs to be transported using transfer equipment. The existing artificial sand transfer equipment does not have the dust reduction function. During the transfer process, dust is easily blown up by the wind, which has a greater impact on the surrounding environment and the physical and mental health of people, and cannot meet the needs of users.

[0003] The existing Chinese patent application number CN202221518307.7 discloses a machine-made sand transfer device with a dust reduction function, which includes a support seat, a support plate is provided on the top of the support seat, a conveying box is provided on the top of the support plate, a feed hopper extending to the inside of the conveying box is provided on the top wall of the conveying box, a baffle plate is provided on the left side of the feed hopper, a discharge hole is provided on the right side of the inner wall of the conveying box, and an extension plate is provided on the right side of the discharge hole. A transmission roller is provided between the front and rear sides of the inner wall of the conveying box and between the two extension plates, and a through-discharge roller is provided between the two transmission rollers. The conveyor belt is provided with a hole, and the conveyor belt fits the bottom of the baffle plate. The interior of the support seat is provided with an adjustment component extending to its top and movably connected to the bottom of the support plate. The adjustment component includes a mounting groove, a mounting groove is provided on the top of the support seat, and a servo motor is provided on the inner bottom wall of the mounting groove. The output shaft of the servo motor is provided with a threaded rod rotatably connected to the right side of the inner wall of the mounting groove, and a threaded block is provided on the outer side of the threaded rod for sliding connection with the inner bottom wall of the mounting groove. The top of the threaded block is provided with a push plate rotatably connected to the bottom of the support plate. A humidifying component extending to the inside of the conveyor box and movably connected to its inner wall is provided on the top of the conveying box and on the right side of the hopper. The device is provided with a water inlet pipe. The user inputs water from the water inlet pipe to the water distributor. The water distributor sprays the water onto the machine-made sand on the conveyor belt through the spray head, so that the machine-made sand remains moist and is not prone to dust. However, due to the excessive length of the conveyor belt, too many spray heads are required, which increases the cost of the equipment. In addition, when the machine-made sand enters the hopper and falls onto the conveyor belt, smoke and dust will inevitably be generated, causing the smoke and dust to float in the conveying box. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a machine-made sand transporting device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0018] like Figure 1 As shown, the utility model provides an artificial sand transfer equipment, which includes a conveying box 1, a conveyor belt 2 and a hopper 3. The artificial sand is conveyed into the conveying box 1 through the hopper 3 and then falls onto the conveyor 2.

[0019] The lower outlet of the hopper 3 is connected to a delivery pipe 4, which is arranged in the delivery box 1. A first motor 4.1 is connected to one side of the delivery pipe 4. A through hole is provided on the side wall of the delivery pipe 4, and the output shaft of the first motor 4.1 passes through the through hole. The output shaft of the first motor 4.1 is connected to a rotating shaft 4.3. Figure 2 As shown, the rotating shaft 4.3 is arranged in the conveying pipe 4, and a group of discharge plates 4.2 are evenly distributed on the circumference of the rotating shaft 4.3. In this embodiment, the number of a group of discharge plates 4.2 is four, and the discharge plates 4.2 are arranged in the conveying pipe 4. When the first motor 4.1 drives a group of discharge plates 4.2 to rotate, the machine-made sand can be evenly discharged from the conveying pipe 4.

[0020] A telescopic tube 5 is connected to the lower side of the conveying pipe 4. In this embodiment, the telescopic tube 5 is a corrugated tube. A cover shell 6 is connected to the lower side of the telescopic tube 5. The cover shell 6 is a circular cover shell. A connecting groove 6.3 is provided on the top of the cover shell 6. The telescopic tube 5 is connected through the connecting groove 6.3. The cover shell 6 is arranged on the upper side of the conveyor belt 2. When the machine-made sand falls on the conveyor belt 2, the smoke and dust generated by the machine-made sand are all in the inside of the cover shell 6 to prevent the smoke and dust from drifting. The cover shell 6 can be moved up and down by the telescopic tube 5. There is a distance between the cover shell 6 and the conveyor belt 2. This distance is used to pass the machine-made sand. The distance between the cover shell 6 and the conveyor belt 2 is adjusted according to the machine-made sand of different particle sizes.

[0021] A driving device 9 is connected to the conveying box 1. The driving device 9 is used to drive the cover 6 to move up and down. The driving device 9 is a second motor. The second motor is connected to the upper side of the conveying box 1. A through hole is provided on the upper side wall of the conveying box 1. The output shaft of the second motor passes through the through hole. A screw 9.1 is connected to the output shaft of the second motor. The screw 9.1 is arranged in the conveying box 1. The screw 9.1 threadably drives the fixed plate 9.2, that is, a threaded through hole is provided on the fixed plate 9.2, and the screw 9.1 is threadedly connected in the threaded through hole. The fixed plate 9.2 is connected to the outside of the cover 6. The screw 9.1 is driven to rotate by the second motor, and the screw 9.1 threadably drives the fixed plate 9.2. The fixed plate 9.2 drives the cover 6 to move up and down.

[0022] A connecting plate 6.1 with a guide hole is connected to one side of the cover shell 6, and a guide rod 6.2 is inserted into the guide hole. The upper end of the guide rod 6.2 is connected to the top of the conveying box 1. The guide rod 6.2 slides in the guide hole so that the cover shell 6 can move up and down smoothly.

[0023] like Figure 3 As shown, a water spraying member 7 is provided in the cover shell 6, and the water spraying member 7 is connected to the water inlet pipe 8. The water inlet pipe 8 is a soft water pipe and is externally connected to a water pump. Water from the outside is pumped by the water pump and then enters the water spraying member 7 through the water inlet pipe 8. The water spraying member 7 includes an annular tube 7.1, which is connected to the cover shell 6 by a snap buckle. A group of nozzles 7.2 are evenly distributed on the circumference of the annular tube 7.1. The water spraying direction of a group of nozzles 7.2 is toward the center of the annular tube 7.1. The circumferentially distributed nozzles 7.2 can spray water on the machine-made sand from all sides, so that the wetting effect of the machine-made sand is better and smoke and dust are prevented from being generated. Even if smoke and dust are generated, they will be in the cover shell 6, which can prevent the smoke and dust from floating.

[0024] When machine-made sand enters from the feed hopper 3 and falls onto the conveyor belt 2, the smoke and dust generated are gathered in the cover 6, preventing the smoke and dust from dispersing to the greatest extent. In addition, the water spraying member 7 arranged in the cover 6 not only reduces the number of spray heads 7.2, but also can better spray water on the machine-made sand.

[0025] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
