Description

Technical Field

[0001] The utility model relates to the technical field of concrete batching equipment, in particular to a raw material batching machine for a concrete mixing station. Background Art

[0002] The raw material batching machine for a mixing station is one of the key equipment in a concrete mixing station. It is mainly used to accurately control the ratio of various raw materials to ensure the stability of the quality of concrete. The equipment is usually composed of a metering system, a conveying system and a control system. The raw material batching machine uses the metering system to accurately measure various raw materials (such as cement, aggregates, sand, additives, etc.) to ensure that the ratio of each material meets the production requirements;

[0003] When the raw material batching machine is in use, some raw materials may sometimes be blocked in the feed hopper of the batching machine. This is mainly because the humidity and particle size of some raw materials change. When the humidity of the raw materials is too high or the particle size is uneven, that is, the gaps between particles with smaller particle sizes are smaller, they are prone to form tight accumulation, resulting in decreased fluidity. At the same time, when the particle size distribution of the raw materials is uneven, large particles are mixed with small particles, which are prone to blockage and bridging. As a result, when the raw material batching machine is discharging raw materials, the raw materials are prone to adhesion or accumulation in the feed hopper, resulting in blockage.

[0022] like Figure 1-Figure 5 As shown, the utility model provides a raw material batching machine for a concrete mixing station, comprising a plurality of batching hoppers 1, a mounting frame 2 is fixedly connected to the lower ends of the plurality of batching hoppers 1, a conveyor 3 is fixedly installed at a position below the mounting frame 2 located inside the mounting frame 2, a mounting beam 4 is fixedly installed on the outer side of the batching hopper 1, a cylinder 5 is movably installed at the middle position of one side of the mounting beam 4, a discharge door 6 is arranged at the lower end of the batching hopper 1, two discharge doors 6 are movably installed at the lower end of the batching hopper 1 through a connecting shaft 9, the two discharge doors 6 are fixedly connected through a connecting plate 7, and the lower end of the connecting plate 7 is axially connected to the output end of the cylinder 5, two sealing sleeves 8 are movably installed on the inner sides of the two discharge ports at the lower end of the batching hopper 1, and a bulking mechanism 10 is fixedly installed on the connecting shaft 9 located in the two discharge ports;

[0023] The bulk material mechanism 10 comprises a mounting hoop 11 and a mounting seat 12 . The mounting hoop 11 is fixedly mounted on the outside of the connecting shaft 9 , while the mounting seat 12 is fixedly mounted on the upper end of the mounting hoop 11 .

[0024] like Figure 3-Figure 4 As shown, two fixing seats 14 are fixedly installed on the inner sides of the two discharge ports at the lower end of the batching hopper 1, and a first clamping groove 15 is provided on the outer side of the fixing seat 14. Through the setting of the fixing seat 14, the sealing sleeve 8 can be quickly disassembled and assembled on the inner side of the batching hopper 1 and the through hole on the inner side of the batching hopper 1 can be closed. The sealing sleeve 8 is made of rubber material, and a clamping ring 16 is fixedly installed on one side of the sealing sleeve 8. The sealing sleeve 8 is clamped on the outer side of the fixing seat 14 through the clamping ring 16;

[0025] like Figure 2-Figure 5As shown, two second slots 18 are provided on the outer side of the connecting shaft 9, and a plurality of flat slots 17 are provided on the connecting shaft 9 located between the two second slots 18. The connecting shaft 9 passes through the transverse through hole and a plurality of sealing sleeves 8 at the lower end of the batching hopper 1, and the second slot 18 is located on one side of the batching hopper 1 and is clamped with a retaining spring 19.
