Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a concrete discharging device. Background Art

[0002] Concrete is today's most important construction material. It is an artificial stone material made by mixing cementitious materials, granular aggregates, water, and, if necessary, admixtures and additives in specific proportions, then uniformly mixing, compacting, and curing to harden. Its abundant raw materials, low cost, and simple preparation have led to a continuously increasing investment in concrete. Concrete also boasts high compressive strength, excellent durability, and a wide range of strength grades. These characteristics have led to its widespread use, not only in various civil engineering projects but also in shipbuilding, machinery, marine development, geothermal projects, and other fields.

[0003] A concrete mixing plant is an important component of a concrete production system. The discharging device installed on the concrete mixing plant transports the mixed and processed concrete to transportation equipment such as concrete mixer trucks. The transportation equipment then transports the concrete to the construction site so that it can be used for construction work at the construction site. The concrete discharging device includes a tank for temporarily storing concrete, a discharge pipe installed at the bottom of the tank, and a discharge valve installed on the discharge pipe. When transporting the processed concrete to transportation equipment such as concrete mixer trucks, it is necessary to first move the transportation equipment below the discharge hopper and align the feed port of the transportation equipment with the bottom end of the discharge pipe in the vertical direction. By opening the discharge valve installed on the discharge pipe, the concrete temporarily stored in the tank is transported to the transportation equipment through the discharge pipe. However, the material tank has a single discharge direction, and the transport equipment must be moved to the designated position before loading operations can be carried out. If the transport equipment is not moved to the designated position, due to the limited moving space under the discharge device, it is often necessary to operate the transport equipment to move out from under the discharge device, adjust the moving position of the transport equipment, and then operate the operating equipment again to face the designated position, thereby affecting the efficiency of the loading operation. In addition, since the material tank has a single discharge port, it is difficult for the discharge device to load multiple transport equipment at the same time. Moreover, the conveying efficiency of the material tank is limited by the diameter of the discharge pipe. For this reason, the concrete discharge device is difficult to meet the requirements of fast loading. Therefore, there is still room for improvement in the discharge of concrete production, so as to facilitate the adjustment of the discharge direction, facilitate the rapid completion of concrete loading, and further promote the transportation of concrete more effectively to meet the growing demand for use.

[0021] like Figures 1 to 6As shown, a concrete discharging device includes a frame 1, two material tanks 2 arranged on the frame 1, and discharge valves 3 respectively arranged at the bottom ends of the two material tanks 2. Two discharge pipes 4 and two guide pipes 5 are respectively arranged below the discharge valves 3. The two discharge pipes 4 are connected to the two material tanks 2 through the discharge valves 3. The tops of the two guide pipes 5 are respectively rotated and sleeved on the two discharge pipes 4. Two arc-shaped discharge pipes 6 are arranged below the guide pipes 5. The two discharge pipes 6 are respectively connected to the two guide pipes 5. The structure is an integrated structure. The bottom end of the discharge pipe 6 is located on one side of the guide pipe 5, so that the discharge pipe 6 and the guide pipe 5 are rotatably mounted on the discharge pipe 4 to facilitate the rotation of the guide pipe 5 and the discharge pipe 6 around the discharge pipe 4. The discharge pipe 4 is provided with a cover plate 7. The two sides of the cover plate 7 are respectively mounted on the two discharge pipes 4. A motor 8 is provided on the cover plate 7. A driving gear 9 is provided on the drive shaft of the motor 8. Two driven gears 10 are engaged on one side of the driving gear 9. The two driven gears 10 are respectively fixed on the two guide pipes 5. The driving gear 9 and the driven gear 10 are driven by the motor 8 to drive the two guide pipes 5 and the two discharge pipes 6 to rotate together, so as to facilitate the adjustment of the discharge direction. In addition, when rapid loading is required, the motor 8 controls the bottom ends of the two discharge pipes 6 to be located between the two guide pipes 5, and then the feed port of the transport equipment is moved below the bottom ends of the two discharge pipes 6. The two guide pipes 5 are used to transport concrete to the transport equipment, facilitating rapid loading of concrete.

[0022] In this embodiment, a box body 11 with an open top is provided below the cover plate 7. The top of the box body 11 is mounted on the bottom surface of the cover plate 7. The driving gear 9 and the two driven gears 10 are located in the box body 11 to protect the driving gear 9 and the two driven gears 10. Two sleeve holes 12 are provided on the bottom plate of the box body 11. The two guide tubes 5 are movably sleeved in the two sleeve holes 12 respectively. The aperture of the sleeve hole 12 coincides with the outer diameter of the guide tube 5, so that the motor 8 can be used to drive the guide tube 5 to rotate.

[0023] Specifically, the middle and lower parts of the guide pipe 5 adopt a trumpet-shaped structure, and the diameter of the middle part of the guide pipe 5 is not less than the diameter of the bottom part of the guide pipe 5, so as to concentrate the discharged concrete and improve the stability of the discharged concrete. The bottom movable sleeve of the guide pipe 5 is provided with a support sleeve 13, and the internal structure of the support sleeve 13 is consistent with the external structure of the bottom of the guide pipe 5. The top end of the support sleeve 13 is installed on the bottom end of the box body 11 to reinforce the support of the guide pipe 5 and improve the stability of the guide pipe 5 during use.

[0024] Please refer again Figure 4The top of the guide pipe 5 is provided with a bearing 14, which is located between the guide pipe 5 and the discharge pipe 4. The outer ring of the bearing 14 is mounted on the inner wall of the guide pipe 5, and the inner ring of the bearing 14 is mounted on the outer wall of the discharge pipe 4, so that the guide pipe 5 can be rotated and mounted on the discharge pipe 4. The top of the bearing 14 contacts the bottom surface of the cover plate 7, and a sealing ring 15 is provided under the bearing 14. The inner wall of the sealing ring 15 is mounted on the discharge pipe 4, and the outer wall of the sealing ring 15 is interference fit on the guide pipe 5, thereby sealing the bearing 14 to prevent impurities such as concrete and dust from entering the bearing 14, thereby ensuring the stable use of the bearing 14.

[0025] Please refer again Figure 1-3 The two material tanks 2 are respectively located on both sides of the frame 1, and a number of fixing frames 16 are respectively provided on the side walls of the two material tanks 2. The number of fixing frames 16 are evenly distributed on the material tank 2 along the circumferential direction of the material tank 2. One side of the fixing frame 16 is installed on the outer wall of the material tank 2, and the bottom end of the fixing frame 16 is provided with a gasket 17 made of elastic material. The two sides of the gasket 17 are respectively installed on the fixing frame 16 and the frame 1, so that the two material tanks 2 are firmly installed on the frame 1, and the connection between the material tank 2 and the frame 1 is buffered to buffer the impact of feeding the material tank 2 and improve the stability of the material tank 2 in use.

[0026] In this embodiment, a three-way reversing valve 18 and a feed valve 19 are sequentially provided above the material tank 2 in the direction away from the material tank 2. The bottom end of the feed valve 19 is installed on the feed end of the three-way reversing valve 18. Two feed pipes 20 are provided between the three-way reversing valve 18 and the material tank 2. The top ends of the two feed pipes 20 are respectively installed on the two discharge ends of the three-way reversing valve 18. The bottom ends of the two feed pipes 20 are respectively installed on the top ends of the two material tanks 2. The feed valve 19 is connected to the top of the material tank 2 through the three-way reversing valve 18 and the feed pipe 20. Concrete is transported to the top end of the feed valve 19 by using conveying equipment such as a hoist and a screw conveyor. The feed valve 19 is controlled to control the path for conveying concrete to the material tank to be closed or started. Then, the three-way reversing valve 18 is controlled to switch the path for conveying concrete to meet the need of conveying concrete to the two material tanks 2.

[0027] Specifically, the tops of the two material tanks 2 are respectively inlaid with material level sensors 21. The detection ends of the material level sensors 21 are located inside the material tank 2, and the detection ends of the material level sensors 21 are toward the bottom of the material tank 2, so as to monitor the material level of the concrete in the material tank 2, so as to facilitate the understanding of the capacity of the concrete in the material tank 2. The material level sensor 21 adopts a radar level sensor‌ or an ultrasonic level sensor, and uses the reflection principle of electromagnetic waves or the propagation principle of sound waves to measure the storage height of the material to meet the need of understanding the capacity of the concrete in the material tank 2.

[0028] The method of using this product is as follows: Figures 1 to 6 As shown, first, the mixed concrete is conveyed toward the feed valve 19 using conveying equipment such as an elevator or screw conveyor. By controlling the opening of the feed valve 19 and adjusting the feed direction of the three-way reversing valve 18, the mixed concrete is added to the two material tanks 2 in sequence. The concrete volume in the material tanks 2 is monitored using a level sensor 21 to prevent excessive concrete volume in the material tanks 2. Next, the feed port of a transport device such as a concrete mixer truck is positioned below the bottom end of the discharge pipe 6. If the feed port of the transport device is difficult to move below the bottom end of the discharge pipe 6, the feed port of the transport device is first operated to move as far as possible below the guide pipe 5, so that the feed port of the transport device moves to the side of the guide pipe 5. Then, by operating the motor 8, the driving gear 9 and the driven gear 10 drive the guide pipe 5 and the discharge pipe 6 to rotate, thereby controlling the bottom end of the discharge pipe 6 to move above the feed port of the transport device, thereby facilitating the delivery of concrete toward the transport device. In addition, since this product has two discharge pipes 6, by controlling the operation of the motor 8, the bottom ends of the two discharge pipes 6 can be controlled to be located between the two guide pipes 5 or on both sides of the two guide pipes 5. To this end, the bottom ends of the two arrangement pipes 6 can be controlled to be offset and adjusted to both sides of the two guide pipes 5, and by moving the feed ports of the two transport equipment to below the bottom ends of the two arrangement pipes 6 respectively, it is convenient to load multiple transport equipment at the same time. Moreover, if it is necessary to quickly complete the loading operation of the transport equipment, first control the bottom ends of the two discharge pipes 6 to be located between the two guide pipes 5, and then move the feed port of the transport equipment to below the bottom ends of the two discharge pipes 6. The guide pipes 5 can be used to transport concrete to the transport equipment to meet the requirements of quickly completing the loading of the concrete. It should be noted that in order to prevent stratification due to the different densities of the various components in the concrete in the concrete tank 2, a stirring device is installed in the tank 2 to maintain the uniformity of the concrete in the tank 2.

[0029] In this embodiment, the discharge valve 3 is provided to control the discharge of concrete from the material tank 2. The top of the guide pipe 5 is rotated and fitted onto the discharge pipe 4 to facilitate the control of the guide pipe 5 and the discharge pipe 6 to rotate around the discharge pipe 4. The motor 8, the driving gear 9, and the driven gear 10 are provided to control the two guide pipes 5 and the two discharge pipes 6 to rotate together to facilitate the adjustment of the discharge direction, so that the concrete discharged from the discharge pipes 6 falls into the feed port of the transport equipment, thereby facilitating the loading of the transport equipment. If rapid loading is required, the motor 8 is used to control the bottom ends of the two discharge pipes 6 to move between the two guide pipes 5, and then the feed port of the transport equipment is moved below the bottom ends of the two discharge pipes 6, so that the two guide pipes 5 can be used to transport concrete to the transport equipment, thereby quickly completing the loading of the concrete.

[0030] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
