Description

Technical Field

[0001] This utility model relates to the field of concrete conveying equipment technology, and specifically discloses a concrete conveying device. Background Technology

[0002] Concrete, often simply called concrete, is a general term for engineering composite materials that bind aggregates together with cementing materials. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water in a certain proportion. It is widely used in civil engineering.

[0003] During the use of concrete, a conveying device is usually needed to transport the concrete to a designated location for use. For example, a concrete cleaning and conveying device for civil engineering proposed in Chinese patent CN214871557U has the advantage that when the concrete is poured onto the concrete truck cover, the concrete baffle is rotated around the hinge by the weight of the concrete and overcomes the tension of the tension spring, thereby opening the concrete inlet and allowing the concrete to enter the concrete truck. After the concrete on the concrete truck cover falls into the concrete truck, the tension spring pulls up the concrete baffle to seal the concrete inlet again. The whole process is completed automatically without manual operation, which is very convenient.

[0004] However, in actual use, it was found that the conveying device has the disadvantage of not being easy to tumble and stir when conveying concrete. This causes the concrete to solidify easily during the conveying process, making it easy for the concrete to accumulate on the inside of the conveying device, solidify easily, and be difficult to clean, thus failing to meet the needs of actual use.

[0005] Furthermore, the discharge pipe of the conveying device can only be kept at one height position, but in construction, it is often necessary to convey concrete at different height positions. The inability to adjust the height of the discharge pipe and the inability to convey concrete at different height positions according to needs result in limited conveying, low practicality, and inconvenience in use. Therefore, we propose a concrete conveying device to solve the above problems. Summary of the Invention

[0006] This utility model proposes a concrete conveying device that has the advantages of easy tumbling and stirring, solving the shortcomings of existing concrete conveying devices that are not easy to tumble and stir; and can convey concrete at different heights according to needs, with no restrictions on conveying.

[0007] This utility model is implemented as follows: a concrete conveying device includes a trolley and a transport box mounted on the trolley base.

[0026] In this embodiment: Concrete is fed into the transport box 2 through the feed hopper 4. The mixing paddle rotates, causing the rotating shaft 7 to drive the large spiral blade 8, the small spiral blade 9, and the scraper 10 to rotate, which can agitate the concrete inside the transport box, preventing the concrete from lumping together. The scraper 10 also prevents the concrete from sticking to the inner wall of the transport box 2, thus ensuring the effectiveness of concrete transportation. The rotation of the small spiral blade 9 also prevents the discharge pipe 5 from being blocked. The sliding sealing plate 6 opens the discharge pipe 5, allowing the concrete in the transport box 2 to be discharged through the discharge pipe 5 and collected by the receiving hopper 13 and transported to the loading pipe 11. The transmission mechanism drives the auger 12 to rotate. The rotation of the auger 12 in the loading pipe 11 can push the concrete towards the downward loading pipe 14. The lifting device 18 is activated, which can adjust the angle of the loading pipe 11, allowing concrete to be transported to different heights as needed, with no restrictions on the transportation.

[0027] As a technical optimization of this utility model, the feeding pipe 11 is provided with a first motor 19, and the output shaft of the first motor 19 is coaxially and fixedly connected to one end of the auger 12.

[0028] In this embodiment: the first motor 19 is started, so that the auger 12 can rotate and push the concrete towards the downward material pipe 14.

[0029] As a technical optimization of this utility model, the two sides of the sealing plate 6 are slidably connected with slide rails 20, the top of the slide rails 20 is provided with a connecting rod 21 fixed to the outer wall of the discharge pipe 5, the discharge pipe 5 is provided with a telescopic device 22, the output end of the telescopic device 22 is provided with a push plate 23, and the telescopic push plate 23 is vertically provided on the top of the sealing plate 6; the lifting device 18 and the telescopic device 22 are electric telescopic rods, pneumatic telescopic rods or hydraulic telescopic rods.

The support frame 25 includes a ring-shaped support sleeve 26 and legs 27 that are equidistantly and vertically arranged at the bottom of the support sleeve 26. The lower end of the legs 27 is fixedly connected to the top of the base of the trolley 1, and the outer wall of the transport box 2 is fixedly connected to the inside of the support sleeve 26.

[0034] In this embodiment, the transport box 2 can be easily fixedly installed on the top of the ejection base by means of the support sleeve 26 and the support leg 27.

[0035] Working principle and usage process of this utility model:

[0036] Concrete is fed into the transport box 2 through the feed hopper 4. The mixing paddle rotates, causing the rotating shaft 7 to drive the large spiral blade 8, the small spiral blade 9, and the scraper 10 to rotate. This agitates the concrete inside the transport box, preventing it from clumping together. The scraper 10 also prevents concrete from sticking to the inner wall of the transport box 2, ensuring efficient concrete delivery. The small spiral blade 9 also prevents blockage of the discharge pipe 5. The telescopic device 22 is activated, causing the push plate 23 to slide the sealing plate 6 between two slide rails 20. The sealing plate 6 automatically opens the discharge pipe 5, allowing the concrete in the transport box 2 to be discharged through the discharge pipe 5 and collected by the receiving hopper 13 and transported to the loading pipe 11. The first motor 19 is activated, and the auger 12 rotates. The auger 12 inside the loading pipe 11 rotates, pushing the concrete towards the downward loading pipe 14. The lifting device 18 is activated, adjusting the angle of the loading pipe 11. This allows for the delivery of concrete to different heights as needed, with unrestricted delivery.
