Embodiment 1

[0030] see figure 1 , figure 2 with image 3 , which shows an embodiment of the present invention's novel elastic stirring blades for concrete hoppers, the concrete hopper 4 is provided with a stirring shaft 3 driven by the stirring motor 1, and the stirring blades 2 are arranged on the stirring shaft 3 , and the mixing blade 2 is provided with an elastic flange 5 at least on the outer edge facing the concrete hopper 4, preferably, the elastic flange 5 is made of elastic non-metallic materials, such as polyurethane or wear-resistant rubber and other elastic non-metallic materials; the minimum distance between the elastic flange 5 and the concrete hopper 4 is 5-20 mm.

[0031] The stirring blade of the present invention can comprise blades of various shapes such as helical shape, in this embodiment, as image 3 As shown, the elastic flange 5 is a strip-shaped flange structure, that is, a continuous elastic non-metallic material flange structure is provided on the outer edge...

Embodiment 2

[0036] see figure 1 , figure 2 , Figure 4 with Figure 5 , which shows another preferred embodiment of the invention. The difference between this embodiment and the above embodiments is that the stirring blade 2 includes at least a first stirring blade 21 and a second stirring blade 22 arranged in pairs on the stirring shaft 3 . Further, the elastic flange 5 is a toothed flange structure arranged at intervals, such as Figure 4 with Figure 5 shown. Preferably, the gap between the elastic flange 51 on the first stirring blade 21 and the elastic flange 52 on the second stirring blade 22 and the tooth-shaped flanges are in complementary positions in space. More preferably, the gap between the elastic flanges is 25-40 mm.

[0037] Specifically, the present embodiment sets discontinuous (such as zigzag or wave-shaped, etc.) elastic non-metallic materials (such as polyurethane, wear-resistant rubber) on the outer edge of the metal stirring blade 2, see Figure 4 with Fi...

Abstract

The invention relates to a novel elastic stirring blade for a concrete hopper. The concrete hopper is internally provided with a stirring shaft which is driven to rotate by a stirring motor. The stirring blade is arranged on the stirring shaft, and the stirring blade is provided with an elastic flange at least on the outer edge facing one side of the concrete hopper. As the elastic flange is employed in the invention, when larger aggregate is stuck between the stirring blade and the concrete hopper, the elastic flange deforms to let the aggregate pass, so that the aggregate cannot be jammed deadly, and no damage can be brought about on the hopper and stirring equipment. In addition, with the invention, a traditional rigid contact relation existing between stirring blades, aggregate and a hopper inner wall when they contact simultaneously is also improved, and the service life of the hopper is improved. Also, the novel elastic stirring blade provided in the invention has the beneficial effects of simple structure, low cost, obvious effect and the like.

Description

technical field [0001] The invention relates to a mechanical stirring mechanism, in particular to a novel elastic stirring blade for a concrete hopper. Background technique [0002] Concrete is generally a semi-fluid material composed of aggregates (stones, etc.), cement, and water. Among them, aggregates (stones, etc.) often have different diameters. In actual engineering, concrete pumps are often used to transport concrete to construction machinery at designated locations, such as concrete pump trucks, truck-mounted concrete pump trucks, and towed concrete pumps. [0003] During transportation and use, the concrete needs to be stirred by a stirring device in the hopper. The hopper, also known as the aggregate, is a container for the pre-pumped concrete; there is a stirring device in the hopper, which is generally composed of a stirring motor, a stirring shaft and a stirring blade, which prevents segregation of the concrete in the hopper and changes the inside of the hopp...
