Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and more specifically, it relates to a sand and gravel mixing device for construction engineering. Background Technology

[0002] In the current construction engineering field, the sand and gravel mixing device, as the core equipment for basic material processing, has not yet fully met the urgent needs of modern construction engineering for efficient and precise mixing. Existing sand and gravel mixing devices cannot easily complete the mixing of sand and gravel in practical applications, which seriously restricts the construction progress and quality control of construction projects.

[0003] Secondly, the existing equipment lacks the function of vibrating and screening the mixed sand and gravel. During the mixing process, large particles of impurities, mud lumps or foreign objects are often mixed in. If they cannot be screened out in time after mixing, it will directly affect the purity and particle size consistency of the sand and gravel, and thus affect the performance of building materials.

[0004] Secondly, after the mixing process is completed, existing equipment often encounters clogging problems during unloading. The unloading pipes used in this way are easily blocked or clogged by sand and gravel during unloading due to unreasonable pipe diameter design, excessively narrow structure, or lack of anti-clogging mechanism. The clogging phenomenon is even more serious when the mixture contains large-particle stone or highly sticky wet sand. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a sand and gravel mixing device for construction engineering, which has the following beneficial effects:

[0031] The output end of the first motor 6 is connected to a drive assembly 10, and one end of the drive assembly 10 is connected to a drive bevel gear 11, which meshes with the driven bevel gear 4.

[0032] A stirring plate 12 is installed inside the rotating cylinder 3, and a fixed seat 13 is installed on the moving vehicle 1. The fixed seat 13 is rotatably connected to the rotating cylinder 3.

[0033] A stirring paddle 14 is connected to the stirring rod 9, and a stirring plate 15 is connected to the bottom of the stirring rod 9. A filter plate 16 is installed inside the feed box 7, and a vibration motor 17 is installed on the filter plate 16.

[0034] One end of the filter plate 16 is connected to an inclined bucket 18, and a feed pipe 19 is connected between the feed box 7 and the rotating cylinder 3. A valve body 20 is installed on the feed pipe 19.

[0035] In this embodiment, sand and gravel are injected along the top of the feed box 7. As the injection continues, the second motor 8 is started, driving the stirring rod 9 at the output end to rotate, and driving the stirring paddle 14 to rotate, thereby dispersing the sand and gravel entering the feed box 7 and making it evenly distributed. In conjunction with the stirring plate 15, the sand and gravel are further dispersed, causing it to fall onto the filter plate 16. By starting the vibration motor 17, the filter plate 16 is vibrated, completing the vibration process of the sand and gravel. Fine sand and gravel are filtered down to the bottom along the filter plate 16. Feed pipe 19, while large pieces of sand and gravel are discharged along inclined hopper 18. The discharge of sand and gravel is completed by control valve body 20, so that it flows into rotating drum 3. By starting the first motor 6 in mounting box 5, the drive assembly 10 at the output end is adjusted, so that the active bevel gear 11 is driven to rotate, so that the driven bevel gear 4 meshing with the active bevel gear 11 is driven to rotate, thereby driving the rotating drum 3 on the driven bevel gear 4 to rotate along mounting sleeve 2 and fixed seat 13, and driving the stirring plate 12 to rotate, so as to complete the process of fully mixing sand and gravel.

[0036] Please see Figure 4 As an embodiment of a construction sand and gravel mixing device with a knocking component: a knocking component is provided at the bottom of the rotating cylinder 3. The knocking component includes a discharge pipe 21, a discharge valve 22 and a mounting frame 23. The discharge pipe 21 is connected to the bottom of the rotating cylinder 3, the discharge valve 22 is installed on the discharge pipe 21, and the mounting frame 23 is connected to the bottom of the rotating cylinder 3.

[0037] Mounting bracket 23 is equipped with a placement seat 24. A third motor 25 is installed at one end of the placement seat 24. The output end of the third motor 25 is connected to a rotating plate 26. A rotating rod 27 is rotatably connected to the rotating plate 26.

[0039] More specifically, after the mixing of sand and gravel is completed, the discharge valve 22 is used to control the discharge of sand and gravel along the discharge pipe 21. In order to prevent the discharge pipe 21 from being blocked, the third motor 25 is started, which drives the rotating plate 26 at the output end to rotate, thereby causing the rotating rod 27 connected to the rotating plate 26 to rotate, and causing the moving block 28 connected to one end of the rotating rod 27 to slide along the placement seat 24. When the moving block 28 slides, the moving rod 29 at one end of the moving block 28 moves, and the striking block 30 on the moving rod 29 is used to complete the striking process of the discharge pipe 21, thereby effectively preventing the discharge pipe 21 from being blocked.

[0040] In summary, during the use or operation of the entire equipment: sand and gravel are injected along the top of the feed box 7. As the injection continues, the second motor 8 is activated, driving the output stirring rod 9 to rotate, which in turn drives the stirring paddle 14 to rotate, thus dispersing the sand and gravel entering the feed box 7 and ensuring even distribution. The stirring blades 15 further disperse the sand and gravel, causing it to fall onto the filter plate 16. The vibration motor 17 is activated, vibrating the filter plate 16 to complete the vibration process of the sand and gravel. Fine sand and gravel are filtered along the filter plate 16. The material is fed through the bottom feed pipe 19, while large pieces of sand and gravel are discharged along the inclined hopper 18. The discharge of the sand and gravel is completed by the control valve body 20, allowing it to flow into the rotating drum 3. By starting the first motor 6 in the mounting box 5, the drive assembly 10 at the output end is activated, causing the active bevel gear 11 to rotate, which in turn drives the driven bevel gear 4, which meshes with the active bevel gear 11, to rotate. This causes the rotating drum 3 on the driven bevel gear 4 to rotate along the mounting sleeve 2 and the fixed seat 13, and also drives the stirring plate 12 to rotate, thus completing the process of fully mixing the sand and gravel.

[0041] After the mixing of sand and gravel is completed, the discharge valve 22 is used to control the discharge of sand and gravel along the discharge pipe 21. In order to prevent the discharge pipe 21 from being blocked, the third motor 25 is started, which drives the rotating plate 26 at the output end to rotate, thereby causing the rotating rod 27 connected to the rotating plate 26 to rotate, and causing the moving block 28 connected to one end of the rotating rod 27 to slide along the placement seat 24. When the moving block 28 slides, the moving rod 29 at one end of the moving block 28 moves, and the striking block 30 on the moving rod 29 is used to complete the striking process of the discharge pipe 21, thereby effectively preventing the discharge pipe 21 from being blocked.
