Description

Technical Field

[0001] This utility model relates to the field of building material production technology, and in particular to a building material production feeding and transportation device. Background Technology

[0002] With the rapid development of the construction industry, the scale and variety of building materials production are also increasing. In the process of building materials production, the transportation and feeding of materials is a crucial link in the production line. Improving production efficiency, reducing energy consumption, and enhancing equipment flexibility and reliability have become urgent needs for the industry's development. Building materials are a general term for materials used in civil engineering and construction engineering. They can be divided into structural materials, decorative materials, and certain special materials. In the process of building materials production, it is necessary to continuously transport building materials into the production equipment.

[0003] The production of existing building materials involves multiple steps, such as crushing and mixing. Each step requires corresponding feeding operations. Crushed materials generally need to be mixed. The feeding port of existing mixing devices is usually located at the top of the device, so manual feeding is inconvenient, time-consuming, labor-intensive, and affects efficiency.

[0004] An existing patent (publication number: CN219238366U) discloses a green and energy-saving building material production feeding device, comprising a production mixing device and a base. Self-locking casters are symmetrically fixed at the four corners of the base's bottom. A mounting seat is fixedly installed at the top center of the production mixing device. A feeding cylinder is inclinedly arranged above the mounting seat. A rotating shaft is rotatably connected to the inner side of the feeding cylinder, and auger blades are arranged on the outer side of the rotating shaft. A housing is installed at the bottom of the feeding cylinder, and a motor is arranged inside the housing. A feeding hopper is arranged on the outer side of the lower end of the feeding cylinder. This green and energy-saving building material production feeding device, through the coordinated arrangement of the base, self-locking casters, mounting seat, feeding cylinder, discharge port, feeding hopper, rotating shaft, auger blades, and motor, can achieve feeding from a low position to a high position, improving efficiency and increasing convenience.

[0005] Existing patents offer solutions to the above problems, but these solutions are prone to clogging at the hopper during material feeding, making it difficult for the feeding cylinder to achieve continuous automated material conveying.

[0006] Therefore, a material feeding and transportation device for building material production is proposed. Utility Model Content

[0010] Preferably, the height adjustment mechanism includes a base disposed below the mounting base, a second electric push rod bolted to the top of the base, an adjustment plate fixedly connected to the output end of the second electric push rod, an inclined groove formed in the middle of the adjustment plate, an adjustment rod fixedly connected to the bottom of the mounting base, the adjustment rod being movably disposed inside the inclined groove, and four support rods fixedly connected to the top of the mounting base, the support rods being movably connected to the mounting base.

[0011] Preferably, the bottom of the adjustment plate is provided with a sliding plate, and the top of the base is fixedly connected with two sliding bars, and the sliding plate is movably connected to the sliding bars.

[0016] Preferably, four self-locking casters are provided below the base, and the four self-locking casters are located at the four corners of the base.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application incorporates an anti-clogging feeding mechanism. This mechanism, driven by a motor, rotates the agitator shaft and impeller, continuously agitating the building material raw materials in the feed hopper. This effectively prevents the raw materials from accumulating and clogging within the hopper, ensuring a smooth supply. The anti-clogging effect is particularly significant when processing highly viscous or easily agglomerated building material raw materials. It ensures the continuity and stability of the production process, reducing production interruptions and equipment failures caused by raw material blockage. Specifically, the feed hopper is fixedly connected to the bottom of the feeding cylinder to receive the building material raw materials, and the agitator shaft bearing is connected to the middle of the feed hopper. The feeding shaft bearing is connected to the middle of the feeding cylinder. Both the stirring shaft and the feeding shaft are equipped with transmission wheels at one end. The two transmission wheels are connected to each other by a transmission belt. The output end of the drive motor bolted to one end of the feeding cylinder is fixedly connected to the feeding shaft. When the drive motor starts, it drives the feeding shaft to rotate. Through the transmission belt, the stirring shaft rotates synchronously. Multiple stirring impellers set in the middle of the stirring shaft stir the building material raw materials in the feeding hopper during rotation, effectively preventing the raw materials from clogging in the feeding hopper, ensuring that the raw materials can smoothly enter the feeding cylinder and be transported to the subsequent production stage with the rotation of the feeding shaft.

[0019] 2. This application incorporates a height adjustment mechanism. This mechanism, utilizing the cooperation of a second electric push rod, an adjusting plate, and an adjusting rod, enables precise adjustment of the feeding cylinder height. When facing production equipment or raw material storage locations of varying heights, the feeding cylinder height can be quickly and conveniently adjusted, ensuring that raw materials can accurately and stably enter subsequent production stages. This further enhances the versatility and adaptability of the device. The first electric push rod drives the feeding cylinder to rotate around the hinge point, achieving flexible adjustment of the feeding angle. This adapts to different feeding angle requirements without requiring large-scale relocation or modification of the entire device, greatly improving the flexibility and adaptability of the production process and meeting diverse production layout needs. Specifically, when the second electric push rod extends or retracts, it drives the adjusting plate to move left and right. Because the adjusting rod moves within the inclined groove, the movement of the adjusting plate forces the adjusting rod to move within the inclined groove, thereby achieving overall height adjustment of the mounting base and the feeding cylinder on it. Simultaneously, four support rods fixedly connected to the top of the mounting base are movably connected to the mounting base, providing stable support and ensuring stability during the height adjustment process.

[0028] 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.

[0029] Please see Figures 1 to 5 This utility model provides a technical solution:

[0030] A material production feeding and conveying device includes a feeding cylinder 1, a mounting base 2 is provided below the feeding cylinder 1, the bottom of the feeding cylinder 1 is hinged to the mounting base 2, the other end of the mounting base 2 is hinged to a first electric push rod 3, the output end of the first electric push rod 3 is hinged to the feeding cylinder 1, an anti-blocking feeding mechanism 4 is provided at the bottom of the feeding cylinder 1, and a height adjustment mechanism 5 is provided below the mounting base 2.

[0031] The anti-clogging feeding mechanism 4 includes a feeding hopper 41 fixedly connected to the bottom of the feeding cylinder 1. A stirring shaft 42 is connected to the middle bearing of the feeding hopper 41, and a feeding shaft 43 is connected to the middle bearing of the feeding cylinder 1. A transmission wheel 44 is provided at one end of both the stirring shaft 42 and the feeding shaft 43. A transmission belt 45 is provided between the two transmission wheels 44. A drive motor 46 is bolted to one end of the feeding cylinder 1. The output end of the drive motor 46 is fixedly connected to the feeding shaft 43. Multiple stirring impellers 47 are provided in the middle of the stirring shaft 42.

[0032] Specifically, such as Figure 3 As shown, a spiral blade 8 is fixedly connected to the side wall of the feeding shaft 43. The side wall of the spiral blade 8 is in contact with the feeding cylinder 1. A discharge port 9 is provided at the top of the feeding cylinder 1.

[0033] In use, building material raw materials first enter the feed hopper 41 at the bottom of the feeding cylinder 1. The agitator shaft 42, connected to the bearing in the middle of the feed hopper 41, begins to rotate under the subsequent power transmission. When the drive motor 46 starts, its output end drives the feeding shaft 43, which is connected to the bearing in the middle of the feeding cylinder 1, to rotate. Since both the agitator shaft 42 and the feeding shaft 43 are equipped with transmission wheels 44 at one end, and a transmission belt 45 is provided between the two transmission wheels 44, according to the transmission principle, the rotation of the feeding shaft 43 will drive the agitator shaft 42 to rotate synchronously through the transmission belt 45. During the rotation, the multiple agitator impellers 47 set in the middle of the agitator shaft 42 continuously agitate the building material raw materials in the feed hopper 41, effectively preventing the raw materials from accumulating and clogging in the feed hopper 41, and ensuring that the raw materials can smoothly enter the feeding cylinder 1. The raw materials are conveyed upwards by the spiral blade 8, pushing them upwards along the inside of the feeding cylinder 1. When the feeding angle of the feeding cylinder 1 needs to be adjusted according to actual production requirements, the first electric push rod 3 is controlled to extend and retract. Since the two ends of the first electric push rod 3 are hinged to the mounting base 2 and the feeding cylinder 1 respectively, when the output end of the first electric push rod 3 extends, it pushes the feeding cylinder 1 to rotate upwards around the hinge point with the mounting base 2, thereby increasing the angle between the feeding cylinder 1 and the horizontal plane. When the output end of the first electric push rod 3 retracts, the feeding cylinder 1 will rotate downwards around the hinge point under the action of gravity, reducing the angle between the feeding cylinder 1 and the horizontal plane. By precisely controlling the extension and retraction length of the first electric push rod 3, the feeding direction of the feeding cylinder 1 can be precisely adjusted, so that it can adapt to different feeding positions and angle requirements.

[0034] Specifically, such as Figure 3 and Figure 4As shown, the height adjustment mechanism 5 includes a base 51 disposed below the mounting base 2. A second electric push rod 52 is bolted to the top of the base 51. An adjustment plate 53 is fixedly connected to the output end of the second electric push rod 52. An inclined groove 54 is provided in the middle of the adjustment plate 53. An adjustment rod 55 is fixedly connected to the bottom of the mounting base 2. The adjustment rod 55 is movably disposed inside the inclined groove 54. Four support rods 56 are fixedly connected to the top of the mounting base 2. The support rods 56 are movably connected to the mounting base 2.

[0035] Specifically, such as Figure 3 As shown, a sliding plate 6 is provided at the bottom of the adjustment plate 53, and two sliding bars 7 are fixedly connected to the top of the base 51. The sliding plate 6 and the sliding bars 7 are movably connected.

[0036] Specifically, such as Figure 3 As shown, the bottom of the skateboard 6 is provided with multiple rollers 10, and the rollers 10 are in contact with the base 51.

[0037] Specifically, such as Figure 5 As shown, four support heads 11 are fixedly connected to the top of the mounting base 2. The support heads 11 are movably connected to the adjusting rod 55. Locking screws 12 are threadedly connected to the side wall of the support head 11. The side wall of the locking screw 12 is in contact with the adjusting rod 55.

[0038] Specifically, such as Figure 5 As shown, four support seats 13 are fixedly connected to the side wall of the base 51, and a support column 14 is threadedly connected to the middle of the support seat 13. A support plate 15 is fixedly connected to the bottom of the support column 14.

[0039] Specifically, such as Figure 5 As shown, four self-locking casters 16 are provided below the base 51, and the four self-locking casters 16 are located at the four corners of the base 51.

[0040] When the height of the feeding cylinder 1 needs to be adjusted, the second electric push rod 52 is activated. As the second electric push rod 52 extends and retracts, it drives the adjusting plate 53 to move left and right. With the up and down movement of the adjusting plate 53, due to the limited movement of the adjusting rod 55 within the inclined groove 54, the adjusting rod 55 moves within the inclined groove 54, thereby pushing the mounting base 2 and the feeding cylinder 1 on it to achieve a change in overall height. To ensure the stability and accuracy of the adjusting plate 53 during movement, a sliding plate 6 is provided at the bottom of the adjusting plate 53. Two sliding strips 7 are fixedly connected to the top of the base 51. The sliding plate 6 is movably connected to the sliding strips 7. This sliding connection provides guidance for the adjusting plate 53, preventing it from shifting during movement. Simultaneously, multiple rollers 10 at the bottom of the sliding plate 6 contact the base 51, converting sliding friction into rolling friction, greatly reducing friction and making the movement of the adjusting plate 53 smoother and more flexible, reducing energy loss and equipment wear. The initial height adjustment is then achieved using the second electric push rod 52. After adjustment, the locking screw 12 can be further tightened by rotating it to fix the adjusting rod 55 inside the support head 11, preventing it from moving during use and ensuring the stability of the height of the feeding cylinder 1. When the device is placed on uneven ground or when enhanced stability is required, the support column 14 can be rotated to make the support plate 15 contact the ground. By adjusting the length of each support column 14, the base 51 can be kept level, improving the overall stability of the device. The support plate 15 increases the contact area with the ground, further enhancing the support effect and preventing the device from shaking or tilting during use. Four self-locking casters 16 are located at the four corners of the base 51. The design of the self-locking casters 16 makes the device flexible and easy to transport and transfer between different production sites. When the device is moved to the designated position, the casters can be locked by the white lock function to prevent the device from moving at will during use and ensure the accuracy and safety of the feeding and transportation process.

[0041] By adopting the above technical solution, the problem that the feeding hopper of the feeding cylinder 1 is prone to blockage during feeding in the existing building material production feeding device is solved, which makes it difficult for the feeding cylinder 1 to achieve continuous and automated material conveying.

[0042] Working Principle: In use, the building material first enters the feed hopper 41 at the bottom of the feeding cylinder 1. When the drive motor 46 starts, its output end drives the feeding shaft 43, which is connected to the bearing in the middle of the feeding cylinder 1, to rotate. Since both the agitator shaft 42 and the feeding shaft 43 are equipped with transmission wheels 44 at one end, and a transmission belt 45 is provided between the two transmission wheels 44, according to the transmission principle, the rotation of the feeding shaft 43 will drive the agitator shaft 42 to rotate synchronously through the transmission belt 45. During the rotation, the multiple agitator impellers 47 provided in the middle of the agitator shaft 42 continuously agitate the building material in the feed hopper 41. The material entering the feeding cylinder 1 is pushed upward by the spiral blades 8. The conveying mechanism pushes the raw materials upwards along the inside of the feeding cylinder 1. When the feeding angle of the feeding cylinder 1 needs to be adjusted according to actual production requirements, the first electric push rod 3 is controlled to extend and retract, which will push the feeding cylinder 1 to rotate upwards around its hinge point with the mounting base 2, thereby increasing the angle between the feeding cylinder 1 and the horizontal plane. When the height of the feeding cylinder 1 needs to be adjusted, the second electric push rod 52 is controlled to start. When the second electric push rod 52 extends and retracts, it drives the adjusting plate 53 to move left and right. As the adjusting plate 53 moves up and down, due to the movement restriction of the adjusting rod 55 in the inclined groove 54, the adjusting rod 55 will move in the inclined groove 54, thereby pushing the mounting base 2 and the feeding cylinder 1 on it to achieve an overall height change.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
