Description

Technical Field

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

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. Concrete is used in construction, which requires mixing and transporting the mixed concrete to a suitable location. To facilitate construction, a concrete conveying and mixing device can be used to facilitate the mixing and transportation of concrete.

[0003] The following problems exist with existing concrete conveying and mixing equipment on the market during actual use:

[0004] 1. In actual use, traditional construction concrete conveying and mixing equipment requires connecting a hose to the equipment during the conveying process. When connecting the hose, the traditional construction concrete conveying and mixing equipment usually fits the hose onto the conveying pipe and uses ropes or wires to wrap around the hose and the conveying pipe to fix it. At this time, the fixation between the hose and the conveying pipe is not stable, and the hose may detach from the conveying pipe, resulting in poor stability during use.

[0005] 2. During the use of most construction concrete conveying and mixing equipment, after the equipment is used, it is necessary to clean it to prevent the concrete from solidifying inside. The water from the cleaning will flow into the conveying equipment. Since the conveying equipment does not have a drainage device, it is necessary to use appropriate tools to drain the water manually, which is inconvenient. Utility Model Content

[0006] The purpose of this utility model is to provide a concrete conveying and mixing device for construction, so as to solve the technical problems mentioned in the background art.

[0029] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a concrete conveying and mixing device for construction.

[0030] like Figure 1-6As shown, this utility model discloses a concrete conveying and mixing device 2, including a conveying device 3, a mixing device 2 mounted on the surface of the conveying device 3, a feeding device 1 at the other end of the mixing device 2, a discharge pipe 4 mounted on the surface of the conveying device 3, and a rigid pipe 7 sleeved on the surface of the discharge pipe 4. The rigid pipe 7 provides an installation base for the connection of the flexible hose 6, allowing the fixing frame 11 to be welded to the surface of the rigid pipe 7, ensuring the stability of the fixing frame 11 after installation. This is very convenient to use. The flexible hose 6 is fixedly connected inside the rigid pipe 7, and the fixing frame 11 is welded to the surface of the rigid pipe 7. A threaded rod 13 is welded to the surface of the conveying device 3. The surface of the fixing frame 11 is attached to the surface of the conveying device 3. The threaded rod 13 passes through the fixing frame 11. A nut 14 is sleeved on the surface of the threaded rod 13. One end of the nut 14 is attached to the surface of the fixing frame 11. By installing the threaded rod 13, passing through the fixing frame 11, and installing the nut 14 on the surface of the threaded rod 13, the fixing frame 11 can be fixed to the surface of the conveying device 3. This fixes the rigid pipe 7 to the surface of the discharge pipe 4. This improves the stability of the connection between the flexible hose 6 and the discharge pipe 4, resulting in stronger stability during use.

[0031] A drain outlet 22 is opened at the bottom of the conveying device 3. A lead screw 17 is installed at the bottom of the conveying device 3. A fixing block 19 is sleeved on the surface of the lead screw 17. A pressure plate 15 is welded to the surface of the fixing block 19. A sealing plug 16 is glued to the top of the pressure plate 15. The sealing plug 16 is embedded in the drain outlet 22. A pressing turntable 20 is sleeved on the surface of the lead screw 17. One end of the pressing turntable 20 is attached to the bottom of the pressure plate 15. At this time, the sewage inside the conveying device 3 can be discharged through the drain outlet 22, which is very convenient to use.

[0032] A fixing ring 8 is welded to the surface of the rigid pipe 7. A groove 9 is opened inside the fixing ring 8. A sealing ring 10 is bonded inside the groove 9. A retaining ring 5 is welded to the surface of the discharge pipe 4. The surface of the fixing ring 8 is attached to the retaining ring 5. The surface of the sealing ring 10 is attached to the surface of the retaining ring 5. By installing the sealing ring 10, the connection between the rigid pipe 7 and the discharge pipe 4 is sealed, so that the material discharged from the discharge pipe 4 will not overflow through the connection between the rigid pipe 7 and the discharge pipe 4. The sealing performance is strong during use.

[0033] The conveying device 3 has a limit frame 12 welded to its surface. The limit frames 12 are symmetrically distributed. The inner wall of the limit frame 12 is attached to the surface of the fixed frame 11. By installing the limit frame 12, after the fixed frame 11 is installed, the limit frame 12 can provide a limiting effect for the fixed frame 11, making the fixed frame 11 more stable after installation and improving its stability during use.

[0034] The bottom of the conveying device 3 is welded with an internal thread seat 18. The internal thread seats 18 are symmetrically distributed. The internal thread seat 18 is fitted with a lead screw 17. By installing the internal thread seat 18, the lead screw 17 can be installed and disassembled. When the lead screw 17 is bent or damaged, it can be replaced, which is very convenient to use.

[0035] A baffle plate 21 is welded to the other end of the lead screw 17. The baffle plates 21 are symmetrically distributed. By installing the baffle plates 21, the baffle plates 21 can provide a limiting effect for the extrusion turntable 20, so that the extrusion turntable 20 will not detach from the lead screw 17, which is very convenient to use.

[0036] The working principle of the concrete conveying and mixing device 2 is as follows: When using this device, first, the rigid pipe 7 should be fitted onto the discharge pipe 4 until the surface of the fixing ring 8 is in contact with the surface of the retaining ring 5, and the external threaded rod 13 should be ensured to pass through the fixing frame 11. Then, the nut 14 should be installed on the surface of the external threaded rod 13 until one end of the nut 14 is in contact with the surface of the fixing frame 11. After that, the device can be used. When using it, the material can be put into the feeding device 1, and then the material will enter the mixing device 2 through the feeding device 1. After the mixing is completed, the mixed concrete will enter the conveying device 3. Internally, a discharge pipe 4 is installed on the surface of the conveying device 3, and a rigid pipe 7 is sleeved on the surface of the discharge pipe 4. A flexible hose 6 is fixedly connected inside the rigid pipe 7.

At this time, the surface of the fixing frame 11 is in contact with the surface of the conveying device 3, and the externally threaded rod 13 passes through the fixing frame 11. A nut 14 is sleeved on the surface of the externally threaded rod 13, with one end of the nut 14 in contact with the surface of the fixing frame 11. Therefore, when using this device, when conveying concrete, the externally threaded rod 13 passes through the fixing frame 11, and a nut 14 is sleeved on the surface of the externally threaded rod 13. Nut 14 is installed on the surface of rod 13 to fix the fixing bracket 11 to the surface of the conveying device 3, thereby fixing the rigid pipe 7 to the surface of the discharge pipe 4. This improves the stability of the connection between the hose 6 and the discharge pipe 4, resulting in strong stability during use. This ensures the connectivity of the hose 6 during concrete conveying. After use, the device needs to be cleaned. A drain outlet 22 is provided at the bottom of the conveying device 3, and a screw rod 17 is installed at the bottom of the conveying device 3. A fixing block 19 is fitted onto the surface of the screw rod 17, and a pressure plate is welded to the surface of the fixing block 19. 15. A sealing plug 16 is bonded to the top of the pressure plate 15. At this time, the sealing plug 16 is embedded in the drain port 22. The extrusion turntable 20 is sleeved on the surface of the screw 17, and one end of the extrusion turntable 20 is attached to the bottom of the pressure plate 15. After the device is cleaned, the sewage will collect inside the conveying device 3. At this time, the extrusion turntable 20 can be rotated until the extrusion turntable 20 is removed from the surface of the pressure plate 15. Then, the pressure plate 15 is moved with the screw 17 until the sealing plug 16 is removed from the drain port 22. At this time, the sewage inside the conveying device 3 can be discharged through the drain port 22, which is very convenient to use.
