Description

Technical Field

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

[0002] Concrete is a general term for a composite material that is made of gel material, aggregate and water in appropriate proportions and hardened after a certain period of time. In the field of road engineering, since the span of concrete to be laid is large, the existing technology often uses a movable cart in combination with a concrete mixing barrel. The mixed concrete is laid on the ground while the cart moves, and then the concrete is compacted by leveling machinery such as rollers to complete the concrete pouring work.

[0003] Most of the existing concrete mixing barrels of cart-type concrete pouring devices are provided with a barrel cover with a threaded connection to prevent concrete from splashing out during the mixing process. Since the threads need to be manually connected, they are prone to tilting during manual operation, causing the threads to disengage, so that the barrel cover cannot be completely closed, resulting in the risk of concrete splashing out. In addition, since the barrel cover and the mixing barrel are detachably connected, the gap at the connection makes it easy for concrete slurry to flow out, resulting in reduced sealing effect of the barrel cover. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the above problems existing in the existing concrete pouring device, the present utility model is proposed.

Since the threads need to be manually connected when connected, they are prone to tilting under manual operation, causing the threads to disengage, so that the barrel cover cannot be completely closed, resulting in the risk of concrete splashing out. In addition, since the barrel cover and the mixing barrel are detachably connected, the gap at the connection makes it easy for the concrete slurry to flow out, resulting in a reduced sealing effect of the barrel cover."

[0026] Reference Figure 1-3 The utility model provides a concrete pouring device, comprising:

[0027] The main unit 100 includes a frame 101, and a cylinder 102 is installed on the top of the frame 101;

[0028] The pouring unit 200 includes a mixing barrel 201, which is installed on the top rear side of the frame 101. A mixing fan blade is arranged inside the mixing barrel 201, and the mixing fan blade is driven by the oil cylinder 102. A barrel cover 202 is arranged on the top of the mixing barrel 201, and a discharge pipe 203 for pouring concrete is installed at the bottom of the mixing barrel 201, and the discharge pipe 203 is controlled to open and close by an electric valve.

[0029] Among them, a mounting sleeve 201b is fixedly connected to the upper inner wall of the mixing barrel 201, and a plurality of groups of connecting threads 201c in a circular array are provided on the inner side of the mounting sleeve 201b. A slot 201d is provided between two adjacent groups of connecting threads 201c. The barrel cover 202 is installed on the top of the mixing barrel 201 through the mounting sleeve 201b and the connecting threads 201c.

[0030] Furthermore, a connecting sleeve 202b is fixedly connected to the bottom of the barrel cover 202, and a plurality of connecting blocks 202c in a circular array and arranged vertically in each group are fixedly connected to the outer wall of the connecting sleeve 202b. The connecting blocks 202c are inclined and fit with the connecting threads 201c. Both ends of the same group of multiple connecting blocks 202c are respectively on the same straight line and movably connected with the slots 201d. The connecting blocks 202c are inserted into the slots 201d, and then as the barrel cover 202 rotates, the connecting blocks 202c spirally move downward along the connecting threads 201c, thereby fixing the barrel cover 202.

[0031] Furthermore, both ends of the connecting thread 201c are shaped to gradually shrink toward the inner wall of the mounting sleeve 201b, and the extension lines between each two adjacent groups of connecting threads 201c are the same straight line, thereby preventing the two ends of the connecting thread 201c from getting stuck with the connecting block 202c, causing the connecting block 202c to be unable to move spirally along the connecting thread 201c.

[0032] Furthermore, an annular connecting groove 201a is provided on the top of the mixing barrel 201, and the connecting groove 201a is arranged on the outside of the mounting sleeve 201b. An inlet hole 201e communicating with the interior of the mixing barrel 201 is provided on the bottom of the inner wall of the mounting sleeve 201b. Concrete raw materials are added to the mixing barrel 201 through the inlet hole 201c, and the opening area of ​​the top of the mixing barrel 201 is reduced by the mounting sleeve 201b, thereby reducing the area where concrete can splash upward during the mixing process, thereby blocking the concrete.

[0033] Furthermore, a rubber sealing ring 202a is fixedly connected to the bottom of the barrel cover 202, and the sealing ring 202a is movably connected to the connecting groove 201a, thereby sealing the connection between the barrel cover 202 and the mixing barrel 201 to prevent the concrete mud from flowing out.

[0034] During use, concrete raw materials are added into the mixing barrel 201 through the feeding hole 201c, and the barrel cover 202 is inserted into the slot 201d through the connecting block 202c. Then, the barrel cover 202 is rotated so that the connecting block 202c moves downward along the connecting thread 201c, thereby driving the barrel cover 202 to move downward and be fixed with the mounting sleeve 201b. The angle and position of the connecting block 202c are positioned by connecting the connecting block 202c with the slot 201d to prevent the barrel cover 202 from tilting and causing the thread to be disengaged. At the same time, the sealing ring 202a is movably connected with the connecting groove 201a to seal the connection between the barrel cover 202 and the mixing barrel 201 to prevent the concrete slurry from flowing out, thereby improving the sealing effect of the barrel cover 202. The mixing barrel 201 is driven by the oil cylinder 102 to stir the concrete. As the frame 101 moves, the discharge pipe 203 is opened to allow the concrete to be laid downward, thereby completing the concrete pouring work.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
