Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, and in particular relates to a material conveying device for concrete production. Background Technology

[0002] Concrete, often simply called PT, is a general term for engineering composite materials made by binding aggregates together with cementing materials. The term usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water, and may contain admixtures and additives, in a certain proportion. It is widely used in civil engineering.

[0003] Concrete production requires material conveying devices. During the concrete production process, materials need to be poured from other equipment into the conveying device for transportation. However, the inlet of existing concrete production material conveying devices is usually fixed at the top, making it difficult for equipment of different heights to effectively convey concrete. This results in significant limitations of the conveying device, which cannot meet the needs of different equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a material conveying device for concrete production. By setting a steel cable, specifically by starting a motor to make the steel cable reel rotate in front of the fixed plate, the steel cable is wound up by the steel cable reel, and the outer surface of the steel cable slides on the outer surface of the pulley. The steel cable pulls the connecting rod upward, thereby moving the feed inlet upward. In this way, the height of the feed inlet can be adjusted according to the height of the feeding equipment, which can meet the needs of different equipment and solve the problem that the fixed feed inlet of the existing concrete material conveying device leads to the great limitation of the conveying device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a material conveying device for concrete production, comprising a feeding assembly and a screw conveyor. The feeding assembly includes a support base, with a base plate fixedly connected to the top of the support base via four support rods. A feeding port is provided on the top of the base plate. A pulley is fixedly connected to the four corners of the bottom of the feeding port, with the outer surface of the pulley slidingly connected to the top of the base plate. A connecting rod is fixedly connected to the left side of the feeding port via a support plate, with a steel cable fixedly connected to the outer surface of the connecting rod. A second pulley is rotatably connected to the top of the support base via two support rods, with the outer surface of the second pulley slidingly connected to the outer surface of the steel cable. A steel cable reel is fixedly connected to the left side of the steel cable, with a fixing plate rotatably connected to the back of the steel cable reel. The bottom of the fixing plate is fixedly connected to the top of the support base. A motor is fixedly connected to the top of the support base near the front of the steel cable reel, with the output end of the motor fixedly connected to the front of the steel cable reel. By rotating the steel cable reel, the steel cable can pull the feeding port to move, allowing the height of the feeding port to be adjusted according to the height of the feeding equipment, thus meeting the needs of different equipment and improving the practicality of the device.

[0007] Furthermore, the top of the base plate has two limiting grooves, and the inner wall of the limiting groove is slidably connected to the outer surface of the pulley. The limiting groove design can prevent the feed port from shifting during the process of being pulled by the steel cable, so that the pulling force can be effectively transmitted and the stability of the device can be greatly improved.

[0008] Furthermore, limiting blocks are fixedly connected to the top and bottom of the limiting groove. The corresponding side of the limiting block contacts the outer surface of the pulley. The limiting block design can prevent the feed inlet from being pulled too high or too low by the steel cable, thus preventing the feed inlet from detaching from the bottom plate and further improving the stability of the device.

[0009] Furthermore, the bottom of the support base is fixedly connected to a base by four support rods, and the base is provided with casters at the four corners of the bottom. The base provides support for the entire device, and the casters at the bottom allow the device to be easily moved to the required position and then fixed, improving the convenience of the device.

[0010] Furthermore, the screw conveyor includes a baffle, inside which shaftless screw blades are rotatably connected. A second motor is fixedly connected to the left side of the baffle via a support frame. The output end of the second motor on the right side is fixedly connected to the left side of the shaftless screw blades. Due to the absence of a central shaft, the shaftless screw blades effectively avoid material entanglement and blockage. Moreover, the conveying capacity of the shaftless screw blades is 1.5 times that of a traditional shafted screw conveyor of the same diameter. This is due to its unique structure and working principle, which makes the material flow more smoothly during the conveying process and improves the conveying efficiency.

[0011] Furthermore, each of the four corners of the baffle is fixedly connected to two fixing blocks via support plates. Support legs are provided on the corresponding side of the two fixing blocks on the left side, and electric push rods are provided on the corresponding side of the two fixing blocks on the right side. The electric push rods can adjust the angle of the shaftless spiral blades according to the height of the conveyed equipment, further improving the practicality of the device.

[0012] Furthermore, a sliding rod is fixedly connected to the top of both the support leg and the electric push rod. A sliding groove is provided inside the fixing block, and the outer surface of the sliding rod is slidably connected to the inner wall of the sliding groove. The design of the sliding groove precisely matches the size and shape of the sliding rod, ensuring that the sliding rod will not deviate from the track during the sliding process, thereby improving the safety and stability of the overall structure.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model uses a steel cable. Specifically, starting motor one causes the steel cable reel to rotate on the front of the fixed plate. At this time, the steel cable is wound up by the steel cable reel, and the outer surface of the steel cable slides on the outer surface of pulley two. The steel cable pulls the connecting rod upward, thereby moving the feed inlet upward. This allows the height of the feed inlet to be adjusted according to the height of the feeding equipment, which can meet the needs of different equipment and improve the practicality of the device.

[0015] 2. This utility model, by setting an electric push rod, specifically by activating the electric push rod to push the push rod upward, while the slide rod slides in the groove on the inner wall of the fixed block to complete the angle adjustment, can adjust the angle of the screw conveyor according to the height of the conveyed equipment, thus further improving the practicality of the device.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Please see Figure 1-5As shown, this utility model is a material conveying device for concrete production, including a feeding assembly 1 and a screw conveyor 2. The feeding assembly 1 includes a support base 11, and a base plate 12 is fixedly connected to the top of the support base 11 by four support rods. A feeding port 13 is provided on the top of the base plate 12. Pulley 131 is fixedly connected to the four corners of the bottom of the feeding port 13. The outer surface of the pulley 131 is slidably connected to the top of the base plate 12. A connecting rod 132 is fixedly connected to the left side of the feeding port 13 by a support plate. A steel cable 134 is fixedly connected to the outer surface of the connecting rod 132. A pulley 233 is rotatably connected to the top of the support base 11 by two support rods. The outer surface of the pulley 233 is slidably connected to the outer surface of the steel cable 134. A steel cable reel 135 is fixedly connected to the left side of the steel cable 134. A fixed plate 136 is rotatably connected to the back of the support base 11. The bottom of the fixed plate 136 is fixedly connected to the top of the support base 11. A motor 137 is fixedly connected to the side of the top of the support base 11 near the front of the cable reel 135. The output end of the motor 137 is fixedly connected to the front of the cable reel 135. By setting the cable 134, specifically by starting the motor 137, the cable reel 135 rotates on the front of the fixed plate 136. At this time, the cable 134 is wound up by the cable reel 135. The outer surface of the cable 134 slides on the outer surface of the pulley 133. The cable 134 pulls the connecting rod 132 upward, thereby moving the feed inlet 13 upward. In this way, the height of the feed inlet 13 can be adjusted according to the height of the feeding equipment, which can meet the use of different equipment and improve the practicality of the device.

[0027] The top of the base plate 12 has two limiting grooves 121, and the inner wall of the limiting groove 121 is slidably connected to the outer surface of the pulley 131.

[0028] Limiting blocks 122 are fixedly connected to the top and bottom of the limiting groove 121, and the corresponding side of the limiting block 122 is in contact with the outer surface of the pulley 131.

[0029] The base 3 is fixedly connected to the bottom of the support base 11 by four support rods, and the four corners of the bottom of the base 3 are equipped with casters.

[0030] The screw conveyor 2 includes a baffle 21, with a shaftless screw blade 22 rotatably connected inside the baffle 21. A motor 23 is fixedly connected to the left side of the baffle 21 via a support frame, and the output end of the motor 23 on the right side is fixedly connected to the left side of the shaftless screw blade 22.

[0031] Each of the four corners of the baffle 21 is fixedly connected to two fixing blocks 24 by a support plate. The two fixing blocks 24 on the left side are provided with supporting legs 241 on the corresponding side, and the two fixing blocks 24 on the right side are provided with electric push rods 242 on the corresponding side.

[0032] A slide rod 243 is fixedly connected to the top of the support leg 241 and the top of the electric push rod 242. A slide groove 244 is opened inside the fixing block 24. The outer surface of the slide rod 243 is slidably connected to the inner wall of the slide groove 244. By setting the electric push rod 242, specifically by activating the electric push rod 242, the push rod of the electric push rod 242 is pushed upward, and at the same time the slide rod 243 slides in the slide groove 244 on the inner wall of the fixing block 24, the angle is adjusted. In this way, the angle of the screw conveyor 2 can be adjusted according to the height of the conveyed equipment, which further improves the practicality of the device.

[0033] A specific application of this embodiment is as follows: In use, firstly, adjust the height of the feed inlet 13 according to the height of the feeding equipment, start the motor 137, and make the cable reel 135 rotate in front of the fixed plate 136. At this time, the cable 134 is wound up by the cable reel 135, and the outer surface of the cable 134 slides on the outer surface of the pulley 133. The cable 134 pulls the connecting rod 132 upward with the pulley 133 as the fulcrum, thereby moving the feed inlet 13 upward. At the same time, the pulley 131 at the bottom of the feed inlet 13 slides on the inner wall of the limiting groove 121. The limiting groove 121 can prevent the feed inlet from shifting during the displacement process, and the limiting block 122 can restrict the movement of the feed inlet 13 and prevent it from coming off. After removing the bottom plate 12, the angle of the screw conveyor 2 is adjusted according to the height of the conveyed equipment. The electric push rod 242 is activated, causing the push rod of the electric push rod 242 to push upward. At the same time, the slide rod 243 slides in the slide groove 244 on the inner wall of the fixed block 24 to adjust the angle. Then, the motor 23 is activated, causing the motor 23 to drive the shaftless screw blade 22 to rotate. When the material enters the baffle 21 from the feed port 13, it will be conveyed to other equipment by the shaftless screw blade 22. The shaftless screw blade 22 is designed to optimize the flow path of the material. Through the unique structure of the shaftless screw blade, the risk of material blockage is greatly reduced, ensuring the smoothness and stability of the device operation.
