Description

Technical Field

[0001] This utility model belongs to the technical field of building material processing equipment, specifically relating to a crushed stone particle size sorting device. Background Technology

[0002] Crushed stone particle size sorting equipment is a key screening device in the production of sand and gravel aggregates. It is mainly used to classify crushed stones according to their particle size to meet the aggregate gradation requirements of different projects. Its background technology originated from traditional screening machinery, such as fixed screens, drum screens, and vibrating screens. In the early days, manual screening was inefficient and had poor accuracy. With the improvement of the automation level of mining machinery, modern sorting equipment has gradually developed towards intelligence, high efficiency and energy saving. It adopts advanced technologies such as multi-layer vibrating screens, airflow separation or photoelectric recognition to achieve continuous and precise particle size classification. This equipment is widely used in infrastructure construction fields such as buildings, highways, railways, and water conservancy, and plays an important role, especially in the production of concrete aggregates, asphalt mixtures and ballast. It is a key piece of equipment to ensure project quality and comprehensive resource utilization.

[0003] Traditional vibrating screening equipment is prone to screen blockage and screening efficiency reduction when operating under high load for a long time; single-layer screen structure is difficult to achieve accurate sorting of multi-level particle sizes, and often requires multiple devices to be used in series, resulting in large footprint and high energy consumption; the strong mechanical vibration generated during equipment operation not only affects screening accuracy, but also shortens the service life of the equipment.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides a crushed stone particle size sorting device, including,

[0026] The support leg 101, the support frame 102 fixedly installed on the surface of the support leg 101, the support plate 103 fixedly installed on the side wall of the support leg 101, the mounting frame 104 fixedly installed on the end of the support leg 101, the screening assembly 105 provided on the surface of the mounting frame 104, and the feeding assembly 106 provided on the surface of the screening assembly 105.

[0027] Specifically, the screening assembly 105 includes a support base 105a fixedly installed on the side wall of the mounting frame 104, and a shock-absorbing spring 105b fixedly installed on the top of the support base 105a. The screening assembly 105 also includes a connecting seat 105c fixedly connected to the end of the shock-absorbing spring 105b, and a screen shell 105d fixedly connected to the side wall of the connecting seat 105c. The screening assembly 105 also includes a vibration motor 105e inserted into the side wall of the screen shell 105d, a screen frame 105f fixedly installed on the inner wall of the screen shell 105d, and a fine hopper 105g connected to the bottom of the screen shell 105d.

[0028] Furthermore, the screen frame 105f has four screens, with screens of varying diameters installed from bottom to top. Different screens can separate crushed stone particles of different diameters, ensuring the screening effect.

[0029] Preferably, the feeding assembly 106 includes a connecting shell 106a fixedly installed on the side wall of the screen shell 105d, and a waste discharge hopper 106b fixedly installed on the top of the connecting shell 106a. The feeding assembly 106 also includes a fixing foot 106c fixedly installed on the side wall of the screen shell 105d, and a primary hopper 106d fixedly installed on the inner wall of the screen shell 105d. The feeding assembly 106 also includes a secondary hopper 106e fixedly installed on the inner wall of the screen shell 105d, and a tertiary hopper 106f fixedly installed on the inner wall of the screen shell 105d.

[0030] It should be noted that the design of the hopper 106b facilitates the separate discharge of stones that are too large in diameter or do not meet the requirements.

[0031] In use, screens of different diameters are installed on the screen frame 105f, raw materials are added into the screening shell 105d, and the vibration motor 105e is started. The vibration motor 105e drives the screening shell 105d to vibrate. The support seat 105a, together with the shock-absorbing spring 105b, ensures the stability of the screening shell 105d during vibration and prevents large swaying. The swaying of the screening shell 105d causes the raw materials to sway, and the raw materials pass through different diameters in stages. The smallest raw materials fall onto the fine hopper 105g after passing through the screen and are discharged through the fine hopper 105g. Larger raw materials are discharged sequentially through the third-stage hopper 106f, the second-stage hopper 106e, and the first-stage hopper 106d. Materials that do not meet the specifications or waste are discharged through the waste hopper 106b. The support plate 103 is designed to facilitate personnel stepping on it and to facilitate observation of the screening situation in the screening hopper.

[0032] In summary, the multi-stage screen frame 105f and the vibrating motor 105e in the screening shell are used in conjunction to achieve efficient and accurate screening of stones of different particle sizes. The combined design of the support base 105a and the shock-absorbing spring 105b effectively suppresses excessive vibration of the screening shell 105d, ensuring the stability of equipment operation. The stepped arrangement of the screen and the matching fine hopper 105g and the first to third stage hoppers 106f can simultaneously complete the separation and collection of materials of multiple specifications. The setting of the impurity discharge hopper 106b further improves the impurity removal capability. The humanized design of the support plate 103 makes it easy for operators to monitor the screening process in real time. The overall structure improves screening efficiency while taking into account operational safety and maintenance convenience, and is suitable for industrial crushing and sorting scenarios.
