[0028] Figure 1 This is a structural diagram of a mud and rock crushing and separation system provided in one embodiment of the present invention.

[0029] In some embodiments, the mud and stone crushing and separation system includes: a chain plate feeding device 101, comprising a mud and stone separator 102 and a roller screen 103 arranged sequentially. The mud and stone separator 102 is provided with a feed inlet for receiving materials that need to be separated and crushed, and is used to perform mud and stone separation operations on the materials; the roller screen 103 is located at the discharge port of the mud and stone separator 102, and is used to screen materials with a diameter of less than a first diameter; a fine material conveyor belt 104, one end of which is located below the roller screen 103, and is used to transport the materials screened by the roller screen 103; and a shaftless drum screen 105, with its feed inlet near the end of the fine material conveyor belt 104, and a screen mesh 106 provided on a portion of the cylindrical surface of the shaftless drum screen 105. 106 is used for screening materials with a diameter of less than the second diameter; the finished product conveyor belt 107 is set below the shaftless drum screen 105 and is used to transport the material screened by the screen 106; the semi-finished product conveyor belt 108 is set at the outlet of the shaftless drum screen 105 and is used to transport the material flowing out of the shaftless drum screen 105; the rotor crusher 109 is set near the end of the semi-finished product conveyor belt 108 and is used to crush the material; the crushed material conveyor belt 110 is set at the outlet of the rotor crusher 109 at one end and at the inlet of the shaftless drum screen 105 at the other end and is used to transport the material crushed by the rotor crusher 109.

[0030] This mud and stone crushing and separation system offers several beneficial effects: multi-stage screening and precise separation. The system employs a mud and stone separator 102, a roller screen 103, and a shaftless drum screen 105 arranged sequentially for multi-stage screening. The mud and stone separator 102 first performs preliminary mud and stone separation, coarsely separating the mud and stone. The roller screen 103 further screens materials with a diameter below a certain threshold, selecting those meeting specific particle size requirements. Finally, the screen 106 of the shaftless drum screen 105 screens materials with a diameter below a certain threshold. This multi-stage screening method enables precise differentiation of materials with different particle sizes, improving the accuracy and quality of material separation. The resulting finished product has a more uniform particle size and lower impurity content, meeting the stringent material requirements of various engineering projects.

[0031] Continuous operation improves efficiency. Various devices are tightly connected via conveyor belts, forming a continuous production process. The chain plate feeder 101 sequentially transports materials to the mud-stone separator 102 and the roller screen 103. The fine material conveyor belt 104 transfers the material screened by the roller screen 103 to the shaftless drum screen 105. The finished product conveyor belt 107, the semi-finished product conveyor belt 108, and the crushed material conveyor belt 110 are responsible for conveying their respective materials. The entire system achieves automatic and continuous material transport without frequent manual intervention, reducing time losses during material transport and greatly improving production efficiency, meeting the needs of large-scale production.

[0032] The cyclic crushing process optimizes particle size. The semi-finished product conveyor belt 108 transports material from the shaftless drum screen 105 that does not meet the particle size requirements to the rotor crusher 109 for crushing. The crushed material is then sent back to the shaftless drum screen 105 for screening via the crushed material conveyor belt 110. This cyclic crushing design allows for multiple crushing and screening of larger particles, ensuring that the final material meets the required particle size. This improves material utilization, reduces waste generation, and lowers production costs.

[0033] The equipment layout is reasonable and space utilization is high. The arrangement of each piece of equipment in the system is compact and reasonable. The mud-stone separator 102 and the roller screen 103 are arranged sequentially on the chain plate feeder 101. The shaftless drum screen 105, the rotor crusher 109, and other equipment are arranged in an orderly manner according to the material conveying process. The setting of each conveyor belt also fully considers the material flow direction. This layout effectively saves production space, facilitates equipment installation, commissioning, and maintenance, and also benefits the management and operation of the production site.

[0034] With a high degree of automation, the system reduces labor intensity. The entire system uses conveyor belts for automatic material transport, and each piece of equipment works collaboratively according to a pre-set process, minimizing manual handling and operation. Operators only need to monitor the equipment's operating status, make necessary parameter adjustments, and perform equipment maintenance, significantly reducing labor intensity and improving the safety and stability of the production process.

[0035] In some embodiments, the mud and stone crushing and separation system includes: a chain plate feeding device 101, comprising a mud and stone separator 102 and a roller screen 103 arranged sequentially. The mud and stone separator 102 is provided with a feed inlet for receiving materials that need to be separated and crushed, and is used to perform mud and stone separation operations on the materials; the roller screen 103 is located at the discharge port of the mud and stone separator 102, and is used to screen materials with a diameter of less than a first diameter; a fine material conveyor belt 104, one end of which is located below the roller screen 103, and is used to transport the materials screened by the roller screen 103; and a shaftless drum screen 105, with its feed inlet near the end of the fine material conveyor belt 104, and a screen mesh 106 provided on a portion of the cylindrical surface of the shaftless drum screen 105. 106 is used for screening materials with a diameter of less than the second diameter; the finished product conveyor belt 107 is set below the shaftless drum screen 105 and is used to transport the material screened by the screen 106; the semi-finished product conveyor belt 108 is set at the outlet of the shaftless drum screen 105 and is used to transport the material flowing out of the shaftless drum screen 105; the rotor crusher 109 is set near the end of the semi-finished product conveyor belt 108 and is used to crush the material; the crushed material conveyor belt 110 is set at the outlet of the rotor crusher 109 at one end and at the inlet of the shaftless drum screen 105 at the other end and is used to transport the material crushed by the rotor crusher 109.

[0036] The first diameter ranges from 5 to 10 cm, and can be 5, 6, 7, 8, 9, or 10 cm. The second diameter ranges from 1.5 to 3 cm, and can be 1.5, 2.0, 2.5, or 3 cm.

[0037] A hopper 111 is installed at the lower end of the inclined section of the fine material conveyor belt 104 near the shaftless drum screen 105. During the process of conveying material screened from the drum screen 103, the inclined section of the conveyor belt may cause material to scatter during movement. The hopper 111 accurately collects this material, preventing it from scattering around the equipment, ensuring complete material transport, preventing waste, and improving material utilization.

[0038] The screen 106 is rectangular in shape. This rectangular shape allows for full utilization of the effective screening area. Compared to other shapes, the rectangle better fits the cylindrical portion of the shaftless drum screen 105, providing a larger screening space as material passes through the screen 106. This allows for simultaneous screening of more material, improving screening efficiency and enabling the processing of more material per unit time, meeting the needs of large-scale production. The regular shape of the rectangular screen 106's apertures facilitates precise size control. This is beneficial for accurately screening materials of specific particle sizes, ensuring a more uniform particle size distribution below the second diameter, improving product quality and consistency, and meeting the stringent particle size requirements of various engineering projects.

[0039] The hopper 111, located near the outlet of the shaftless drum screen 105, can accurately collect and guide the material flowing out of the screen. The shape and position design of the hopper 111 ensures that the material falls accurately onto the semi-finished product conveyor belt 108, preventing material spillage or deviation from the conveyor belt, and ensuring the stability and accuracy of material conveying.

[0040] A hopper 111 is provided at the lower end of the inclined section of the crushing conveyor belt 110 near the shaftless drum screen 105. Material conveyed from the discharge port of the rotor crusher 109 via the crushing conveyor belt 110 may disperse upon reaching the lower end of the inclined section of the shaftless drum screen 105 due to conveyor belt movement and drop. The hopper 111 efficiently collects this dispersed material, preventing material spillage and ensuring that the material enters the shaftless drum screen 105 intact for further screening. This not only improves material utilization and reduces waste but also ensures a stable material quantity throughout the production process, providing favorable material conditions for subsequent screening. Preferably, a guide hopper is provided at the feed inlet of the shaftless drum screen 105 to guide the material conveyed on the crushing conveyor belt 110 into the shaftless drum screen 105, and can also guide the material conveyed on the fine material conveyor belt 104 into the shaftless drum screen 105.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of the present utility model.
