DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will further describe the present utility model in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0020] As Figures 1 - 5As shown, a hydraulic rolling concrete uphill conveying device includes a conveying roller 1, a supporting roller 2, a stop roller 3, a driving device 4, a feed port 5, and a discharge port 6; the conveying roller 1 has a front vertebra 109 and a tail vertebra 102 at both ends, and a tank body 104 in the middle, which is connected by a flange 105 with a gear on the outside, and the cylinder body has regularly distributed raceways 103, and the feed end raceway is a stop raceway 108. The feed end is composed of a feed barrel 110 and a front vertebra 109, and the feed barrel 110 has a flared mouth. The interior of the central cylindrical tank body is a strip spiral blade structure 107, and the tank body is provided with an inspection hole 106 and a hole cover. The discharge end is composed of a tail vertebra 102 and a guide cone 101, and the guide cone 101 has a trumpet mouth; the specifications of the support roller 2 and the stop roller 3 are adapted to the roller raceways 103 and 108, the support roller 2 supports the roller body, and the stop roller 3 at the feed end stops the roller from shifting; the drive device 4 is chain-linked to the outer gear of the flange 105 to drive the roller 1 to roll; the feed port 5 and the discharge port 6 are funnel-shaped to collect and convey materials, and the drive device 4 is a hydraulic transmission device.

[0021] The front vertebra 109 and the tail vertebra 102 are arranged at both ends to reduce the overall open area, effectively reducing the leakage and waste of concrete materials when the drum is running; the strip spiral blades 107 arranged inside are conducive to the fixed-point rotation to realize the transportation of the internal mixed concrete; the inspection hole 106 arranged on the tank body is convenient for inspection, maintenance and care during use.

[0022] The stop roller 108 is provided to ensure that no forward or backward displacement occurs during operation, and the feeding cylinder 110 with a bell mouth and the guide cone 101 are provided to greatly improve the efficiency of feeding and discharging materials.

[0023] The various parts of the above-mentioned roller 1 are connected by a flange 105 with a gear on the outside. The roller 1 can be directly driven by a chain link, and the conveying roller tank can be selectively increased or decreased according to the transportation distance, which can be connected only by the flange 105 with a gear on the outside, which has high flexibility and practicality in the specific application environment.

[0024] When conveying, first start the drive device 4 to drive the roller 1 to roll at a constant speed. The drive device 4 adopts a hydraulic drive device, which has the characteristics of small size, light weight, compact structure, and long service life, and the transmission motion is balanced, which ensures the uniform rolling of the roller. The concrete material to be mixed enters the roller from the feed port 5 and follows the strip spiral blades 107 to be transported to the roller outlet 6 to complete the conveying process. If there is an abnormality in the conveying process, the inspection hole cover can be opened after closing the drive device 4 for inspection and maintenance. After the mixed concrete material to be transported is basically all sent out from the roller outlet 6, turn off the drive device 4 to end the conveying operation. It is achieved in an uphill conveying operation environment while ensuring the quality of the mixed concrete material and efficient transportation, and it is simple to operate and safe to use, and the required space position is not large and relatively fixed.

[0025] By using this device, the required mixed concrete can be efficiently transported from a low position to a high-position feeding point, reducing problems such as segregation and delamination of the mixed concrete, loss of cement slurry, change in slump value, and initial setting of the concrete during the transportation process; at the same time, its semi-closed feature can ensure civilized construction at the construction site and avoid the problem of dealing with the leakage of the mixed concrete. In addition, this device is easy to use. Just start the driving device 4 to drive the conveying drum 1 to roll to complete the conveying work. This can improve the construction efficiency of the concrete project and ensure the quality of the concrete. Moreover, this device can selectively increase or decrease the conveying drum tank body 104, having high flexibility and practicality in specific application environments. Generally speaking, a hydraulic rolling type concrete uphill conveying device of the present application can effectively solve the problems existing in the prior art and has practical application benefits.
