Problems solved by technology
Its operation is cumbersome, and it cannot be adapted to local conditions, and the equipment cost is high. Moreover, the flow of water often drives the movement of sediment. In natural rivers, the interior of sand waves shows strict spatial heterogeneity, and mechanical dredging fails to take into account the influence of natural water flow

Embodiment Construction
[0029] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0030] The present invention relates to an on-site sorting system for river sediment with different particle sizes, comprising a sand mixing device 100 for mixing sediment with different particle sizes, a sediment buffer device 300 and a sediment sorting device 200 . The silt mixed in the sand mixing device 100 enters the silt sorting device 200 through the silt buffer device 300 for on-site sorting.
[0031] Such as figure 1 As shown, the sand mixing device 100 includes a support rod 101 , a wheel shaft 102 , a vibration tank 103 , a collection tank 104 , a snap ring 105 and a vibration source 106 . The support rods 101 are two opposite supports placed on the ground, the support rods 101 are provided with notches, and the two ends of the axle 102 are respectively inserted into the notches of the support rods on both sides. The wheel shaft 1...

The invention discloses an on-site sorting system for river sediment with different grain diameters. The on-site sorting system comprises a sediment mixing device for mixing the sediment with the different grain diameters, and a sediment sorting device. The sediment mixing device comprises two supporting rods arranged oppositely. A wheel shaft is connected between the supporting rods. The wheel shaft is sleeved with a vibration groove which can rotate along with the wheel shaft and is used for mixing the sediment. A collecting groove used for collecting mixed sediment is arranged below the vibration groove. The sediment sorting device comprises a water inlet device, a to-be-sorted sediment tank, a vertical sorting pipeline, a tail sediment collecting device and a drainage device which are sequentially connected, wherein the water inlet device is used for providing water flow for flushing the sediment, the to-be-sorted sediment tank is used for storing the mixed sediment, and the vertical sorting pipeline is used for dividing flow of the sediment with the different grain diameters. According to the system, the natural physical property of the water flow is utilized, on-site sampling is carried out beside a river, by means of the reasonable structural design, on-site sorting of the sediment with the different grain diameters is achieved, and the system is simple in structure, high in operability and capable of saving a large amount of transporting time and cost.
Description
technical field [0001] The invention relates to a sediment sorting system and a use method thereof, in particular to an on-site sorting system and a use method of river sediment with different particle sizes. Background technique [0002] Among natural rivers, there are many rivers with a lot of sediment. The problem of sedimentation in rivers and reservoirs is very serious, and it is also an important cause of many natural disasters. River sedimentation brings many hazards: (1) bank erosion and shoreline shifting back, endangering the safety of residential buildings (structures) on the bank, as well as public facilities such as transportation, energy, farmland, and water conservancy; (2) riverbed silting Shallow, flood discharge and flood discharge capacity decline, affecting shipping and causing flooding; (3) estuary siltation causes serious degradation of harbor functions, affecting the sustainable development of port cities. In addition, the problem of sedimentation in ...
