Description

Technical Field

[0001] This utility model belongs to the field of concrete additive conveying technology, specifically a concrete additive directional conveying device. Background Technology

[0002] Concrete additives are substances added during the concrete mixing process to improve the performance of concrete. There are many types of concrete additives, each with its own unique function and application scenarios. Types of concrete additives include water-reducing agents, early-strength agents, retarders, air-entraining agents, and waterproofing agents, among others.

[0003] Traditional conveying devices used for transporting concrete additives are mostly fixed and supported by welded steel frames. This makes it difficult to adjust the height or angle of the conveying device, and the device is bulky and difficult to move, thus affecting its actual construction use. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a concrete additive directional conveying device, which solves the problem that fixing the conveying device with a welded steel frame makes it difficult to adjust the height or angle of the conveying device, and makes it bulky and difficult to move, thus affecting its actual construction use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete additive directional conveying device, comprising a base frame, a plurality of universal wheels installed below the base frame, a sliding groove provided on the base frame, a connecting rod connected to one side of the base frame, a conveying pipe rotatably connected to the base frame via the connecting rod, a first motor fixedly installed on the other side of the base frame, a threaded screw connected to the output shaft of the first motor, a slider installed on the threaded screw, and a guide sleeve connected to the slider;

[0006] The slider is rotatably connected to a hinge rod via a pin. The conveying pipe is connected to a filling port and a discharge port. A second motor is fixedly installed at one end of the conveying pipe. The output shaft of the second motor is connected to a rotating rod. A spiral auger is installed on the rotating rod. Connecting plates are connected to both ends of the rotating rod. Multiple scrapers are connected to the connecting plates.

[0007] As a further embodiment of this utility model: there are three scrapers in total, and the whole is designed in an arc shape. The three scrapers are evenly connected on the connecting plate in a centrally symmetrical manner, and the scrapers are in contact with the wall of the transport pipe.

[0008] As a further embodiment of this utility model: a connector is connected to one side of the transport pipe, a fixing member is connected to the transport pipe, and the rotating rod is rotatably connected inside the transport pipe.

[0009] As a further embodiment of this utility model: the threaded screw is rotatably connected in the slide groove, and the guide sleeve is threadedly engaged with the threaded screw.

[0010] As a further embodiment of this utility model: the slider slides within the groove, and both sides of the slider are in contact with the groove wall.

[0011] As a further embodiment of this utility model: the connecting member is rotatably connected to the connecting rod, and the end of the hinge rod away from the slider is rotatably connected to the fixing member through a pin.

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

[0013] 1. This concrete additive directional conveying device comprises a first motor, a threaded screw, a slider, a hinged rod, a connector, a connecting rod, and casters. By starting the first motor and rotating the threaded screw, the slider moves along the threaded screw via a guide sleeve. As the slider moves, the two ends of the hinged rod rotate, causing the hinged rod to push the conveying pipe. This causes the connector to rotate around the connecting rod, thereby adjusting the angle of the conveying pipe and gradually raising the height of the discharge port. This improves the applicability of the conveying device to meet different work requirements. The casters facilitate the movement of the conveying device by the operator.

[0014] 2. This concrete additive directional conveying device is equipped with a second motor, a rotating rod, a spiral auger, connecting plates, and scrapers. By starting the second motor and rotating the rotating rod, the spiral auger can directionally transport the concrete additive. At the same time, the rotating rod will drive the connecting plates at both ends to rotate, which in turn will cause the scrapers to rotate. The scrapers can scrape off the material adhering to the wall of the conveying pipe to avoid sticking residue. The three arc-shaped scrapers increase the contact surface with the wall of the conveying pipe, thereby improving the scraping effect. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a concrete additive directional conveying device, including a base frame 1, multiple casters 2 installed below the base frame 1, a sliding groove 3 opened on the base frame 1, a connecting rod 4 connected to one side of the base frame 1, a connecting member 18 rotatably connected to the connecting rod 4, and a hinge rod 10 at the end away from the slider 8 rotatably connected to a fixing member 19 through a pin. By rotating the hinge rod 10, when the slider 8 moves, the hinge rod 10 can push the conveying pipe 5, causing the connecting member 18 to rotate on the connecting rod 4, thereby adjusting the working angle of the conveying pipe 5, and thus changing the discharge height of the discharge port 12 to meet different working requirements.

[0022] The base frame 1 is rotatably connected to the transport pipe 5 via the connecting rod 4. A connector 18 is connected to one side of the transport pipe 5, and a fixing member 19 is connected to the transport pipe 5. The rotating rod 14 is rotatably connected inside the transport pipe 5. The rotating rod 14 is driven to rotate inside the transport pipe 5 by the second motor 13, so that the spiral auger 15 can transport the concrete additive from the filling port 11 to the discharge port 12 to complete the directional conveying work.

[0023] A first motor 6 is fixedly installed on the other side of the base frame 1. The output shaft of the first motor 6 is connected to a threaded screw 7. The threaded screw 7 is rotatably connected in the slide groove 3. The guide sleeve 9 is threadedly engaged with the threaded screw 7. Through the threaded engagement between the guide sleeve 9 and the threaded screw 7, the slider 8 can move along the threaded screw 7 when the threaded screw 7 rotates, thereby changing the angle of the hinge rod 10. This causes the hinge rod 10 to push the transport pipe 5 to change the working angle of the transport pipe 5, thus improving the applicability of the conveying device.

[0024] A slider 8 is installed on the threaded screw 7. The slider 8 slides in the groove 3. The two sides of the slider 8 are in contact with the groove wall of the groove 3. Through the contact between the slider 8 and the groove wall of the groove 3, the groove 3 can guide the slider 8, thereby preventing the slider 8 from rotating and enabling the slider 8 to move smoothly.

[0025] A guide sleeve 9 is connected to the slider 8, and a hinge rod 10 is rotatably connected to the slider 8 via a pin. A filling port 11 is connected to the transport pipe 5, and a discharge port 12 is connected to the transport pipe 5. A second motor 13 is fixedly installed at one end of the transport pipe 5. The output shaft of the second motor 13 is connected to a rotating rod 14. A spiral auger 15 is installed on the rotating rod 14. Connecting plates 16 are connected to both ends of the rotating rod 14. Multiple scrapers 17 are connected to the connecting plates 16. There are three scrapers 17 in total, and they are designed in an arc shape. The three scrapers 17 are evenly connected to the connecting plates 16 in a centrally symmetrical manner. The scrapers 17 are in contact with the wall of the transport pipe 5. By scraping the wall of the transport pipe 5 simultaneously with multiple scrapers 17, the attached residual additives are cleaned and removed, reducing waste.

[0026] The working principle of this utility model is as follows:

[0027] By starting the first motor 6 to rotate the threaded screw 7, the guide sleeve 9 and the threaded engagement of the threaded screw 7 allow the slider 8 to move along the threaded screw 7. As the slider 8 moves, the two ends of the hinge rod 10 will rotate, thereby pushing the transport pipe 5 and causing the connector 18 to rotate on the connecting rod 4. This adjusts the angle of the transport pipe 5 and raises the discharge height of the outlet 12, thus improving the applicability of the conveying device to meet different working needs. By rotating the rotating rod 14 with the second motor 13, the auger 15 can transport the concrete additive from the filling port 11 to the outlet 12, thereby completing the directional conveying. At the same time, the rotating rod 14 will drive the connecting plates 16 at both ends to rotate, thereby causing the scraper 17 to rotate. The scraper 17 can scrape off the material adhering to the wall of the transport pipe 5 to avoid the concrete additive sticking and remaining.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
