Problems solved by technology

[0003] The screening and mixing of sand and gravel is generally realized by mechanical equipment, while the existing sand and gravel mixing device generally realizes the screening work directly through the screen, and then stirs and mixes through the stirring rod. The screening effect of this structure during use Not good, it is easy to be blocked, and at the same time, it is impossible to control the stirring time during use, so that the effect of stirring cannot meet the requirements, making the overall practicability poor

Embodiment 1

[0027] see Figure 1~5 , in an embodiment of the present invention, a gravel mixing device for road construction, including a support assembly 01, a mixing box 02 is fixed on the support assembly 01, and the mixing box 02 communicates with the feeding assembly 03 above, and the feeding assembly 03 can The incoming sand and gravel are screened first, and then enter the mixing box 02, and the mixing box 02 is connected to the storage box 04 on one side, so that the mixed sand and gravel can enter the storage box 04 for storage, which is very simple; A fixed plate 21 is fixed inside the mixing box 02, and a water adding component 05 and a mixing component 06 are arranged above the fixing plate 21, through which water can be added to the gravel through the water adding component 05, and the mixture can be stirred through the mixing component 06 , to play a very good mixing effect, and at the same time, a control component 07 is also provided on the fixed plate 21. The control comp...

Embodiment 2

[0038] The storage box 04 is provided with a paving assembly 08, through which the ground can be paved conveniently, so that it can be stored and paved on the ground, which has very good practicability; The paving assembly 08 includes a fixed frame 81 in the fixed storage box 04, a second guide rod 82 is fixed on the fixed frame 81, a movable plate 83 is slidably connected on the second guide rod 82, and the top of the movable plate 83 is connected with the telescopic cylinder 84 The output end is fixedly connected. When the telescopic cylinder 84 is working, it can drive the moving plate 83 to move in the horizontal direction. The moving plate 83 is fixedly connected to the second stopper 86 through the third connecting rod 85. The second stopper 86 is set on the discharge channel. 87 above; when storing, the second stopper 86 stays at the top of the discharge channel 87, and the mixture in the storage box 04 cannot flow out at this moment, and when the second stopper 86 leave...

Abstract

The invention discloses a sand-gravel mixing device for road construction, and relates to the technical field of road construction. The sand-gravel mixing device for road construction comprises a supporting assembly, wherein a mixing box is fixed on the supporting assembly; the mixing box is communicated with a feeding assembly above the mixing box; the mixing box is further communicated with a storage box on one side; a fixing plate is fixed in the mixing box; a water adding assembly and a uniform mixing assembly are arranged above the fixing plate; a control assembly is further arranged on the fixing plate; and a paving assembly is arranged in the storage box. The feeding assembly can play a role in screening sand and gravel, then the subsequent sand and gravel mixing effect is improved,the screening effect can be improved through a rotating shaft and a lifting block in the feeding box, large-particle impurities can be prevented from blocking the screening net through a scraping block above the screening net, and the screening effect is further improved; and through the paving assembly, the ground can be conveniently paved, so that storage can be conducted, paving of the groundcan be achieved, and very good practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a sand and gravel mixing device for road construction. Background technique [0002] Sand and gravel refers to a loose mixture of sand grains and gravel. Because of its good hardness and stable chemical properties, sand and gravel are often used as high-quality building materials and concrete raw materials and are widely used in housing, roads, highways, railways, engineering and other fields. Now urban construction, road construction and other building construction projects need to use a large amount of sand and gravel concrete, and in different engineering constructions, there are different requirements for the particle size and uniformity of sand and gravel, so it will be involved in civil engineering Screening and mixing operations to a large amount of sand and gravel. [0003] The screening and mixing of sand and gravel is generally realized by mechanical equipme...
