Description

Technical Field

[0001] This utility model relates to the field of sand making equipment technology, and in particular to a sand making machine frame station. Background Technology

[0002] In the construction of infrastructure such as buildings, roads, and bridges, sand and gravel aggregates are indispensable key raw materials. With the increasing depletion of natural sand resources and tightening environmental protection policies, manufactured sand has become the mainstream choice. As the core equipment for producing high-quality manufactured sand, the performance and stability of the sand making machine directly determine the particle shape, gradation, and production capacity of the final product.

[0003] Traditional sand making machine installation methods typically employ concrete foundation stations. This method requires large-scale on-site excavation and concrete pouring to construct a robust, permanent concrete foundation to secure and support the sand making machine and its associated equipment. This installation method has several inherent drawbacks: 1. Long construction period and high cost: The construction of concrete foundations involves multiple stages, including surveying, excavation, formwork, pouring, and curing. The entire process is time-consuming and labor-intensive, with high costs for raw materials and labor. This seriously affects the project's commissioning schedule, especially in projects with tight deadlines or in remote areas.

[0004] 2. Poor flexibility and difficulty in relocation: Concrete foundations are permanent structures; once built, the entire production line is fixed there. When the source of raw materials changes, the project needs to be relocated upon completion, or the production layout needs to be adjusted according to market demand, the original concrete foundation can only be abandoned. The cost of dismantling equipment and rebuilding at a new site is extremely high, resulting in a huge waste of resources.

[0005] 3. Poor site adaptability: For construction projects with complex terrain, uneven sites, or temporary projects, constructing a qualified concrete foundation is difficult, or even impossible. In addition, the seismic design and settlement treatment of the foundation also increase technical complexity and cost.

[0006] 4. Challenges in Installation Accuracy and Stability: Although concrete foundations are theoretically very stable, their construction quality is easily affected by human and environmental factors. Uneven settlement of the foundation or deformation of the formwork can lead to a decrease in the installation accuracy of the equipment, causing a series of problems such as increased vibration during the operation of the sand making machine, accelerated bearing wear, and shortened life of transmission components, affecting the stability and continuity of production.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see the appendix Figure 1-3 This embodiment provides a sand making machine frame station, comprising a fixed frame 1, a sand making machine 2 fixedly connected to the middle of the fixed frame 1, a feed inlet at the upper end of the sand making machine 2, a discharge outlet at the lower end of the sand making machine 2, a feeding frame 3 fitted at the feed inlet, the feeding frame 3 being hinged to the fixed frame 1, a feeding belt conveyor 11 rotatably connected to the feeding frame 3, and a discharge frame 4 fitted at the discharge outlet, a discharge belt conveyor 12 rotatably connected to the discharge frame 4.

[0022] The fixed frame 1 is welded from high-strength steel (such as H-beams and square steel). This fixed frame 11 constitutes the core load-bearing structure of the entire device. Its bottom can be equipped with mounting holes for connection to the foundation or outriggers for easy transportation. It has sufficient rigidity and strength to effectively withstand the high-frequency vibration and impact loads generated during the operation of the sand making machine 2, replacing the traditional concrete foundation. The sand making machine 2 is fixedly installed on the middle platform of the fixed frame 1 with high-strength bolts and vibration-damping rubber pads. The upper end of the sand making machine 2 is equipped with a feed inlet for receiving the material to be crushed; the lower end is equipped with a discharge outlet for discharging the crushed sand. A feeding rack 3 is provided at the feed inlet. The tail end (lower end) of the feeding rack 3 is hinged to the fixed frame 1 through a heavy-duty hinge seat, allowing the feeding rack 3 to be tilted and adjusted within a certain angle around the hinge point. The feeding frame 3 is rotatably connected to the feeding belt 11 via bearing seats and drive rollers, which is used to continuously and stably transport materials to the feed port of the sand making machine 2; a discharge frame 4 is located directly below the discharge port, and a discharge belt 12 is also rotatably connected to the discharge frame 4 via bearing seats, which is used to receive and transfer the sand material processed by the sand making machine 2, and transport it to the next process (such as screening station) or stockpile.

[0023] The entire sand making system (sand making machine 2, feeding rack 3, and discharge rack 4) is integrated onto a single rigid fixed frame 1, forming a complete and modular production unit. During relocation, the feeding rack 3 and discharge rack 4 can be adjusted to a suitable transport configuration, and the entire frame station can be transported away as a whole by trailer, achieving rapid deployment and relocation. This completely solves the inherent drawbacks of traditional concrete foundations, such as long construction cycles and immobility. During operation, materials are conveyed by the feeding belt conveyor 11, entering the sand making machine 2 through the inlet. The crushed sand falls from the outlet onto the discharge belt conveyor 12 and is then transported out. The integrated design ensures the relative positional accuracy between the various devices, reduces installation and commissioning time, and improves the stability and efficiency of the entire production line.

[0024] On both sides of the main structure of the feeding rack 3, there are sliders 5. The sliders 5 are slidably connected to the guide rails or grooves on the side of the feeding rack 3. A support rod 6 is hinged to the bottom of each slider 5. The lower end of the support rod 6 is connected to the fixed frame 1 through a hinge seat, thus forming a variable triangular support mechanism together with the feeding rack 3 and the sliders 5. In this triangular mechanism, a hydraulic rod 7 is hinged to the middle of the support rod 6. The other end of the hydraulic rod 7 is also connected to the corresponding hinge point on the fixed frame 1.

[0025] By controlling the extension and retraction of the hydraulic rod 7, the support rod 6 can be precisely pushed or pulled, causing it to rotate around its lower hinge point. The rotation of the support rod 6 then drives the slider 5 to slide along the feeding frame 3, ultimately achieving stepless and smooth adjustment of the overall pitch angle of the feeding frame 3. This hydraulic drive structure allows users to flexibly and quickly adjust the tilt angle of the feeding conveyor belt 11 according to different site conditions and material heights, greatly enhancing the site adaptability of the equipment. At the same time, the hydraulic system has a built-in locking function, providing strong locking force to ensure the absolute stability of the feeding frame 3 when conveying heavy materials, avoiding possible shaking during operation.

[0026] The discharge rack 4 specifically includes a first bracket 401 and a second bracket 402. The bottom of the first bracket 401 is fixedly connected to the fixed frame 1, providing basic support. The first end of the second bracket 402 (used to mount the discharge conveyor 12) is connected to the top end of the first bracket 401 via a transverse hinge shaft, allowing the second bracket 402 to rotate relative to the first bracket 401 within a certain angle range. Below the tail end of the second bracket 402, an adjusting rod 403 is hinged. The other end of the adjusting rod 403 is hinged to a hanger 404, which is fixedly connected to the side or top of the fixed frame 1.

[0027] The hanger 404 can be designed as an inverted L-shaped structure to provide a better lever arm and clear installation space. The adjusting rod 403 can be a manual telescopic rod structure (e.g., composed of threaded inner and outer sleeves and a locking nut) or a hydraulic / pneumatic telescopic cylinder, which can adjust and fix the tilt angle of the second bracket 402 by changing its own length.

[0028] When it is necessary to adjust the discharge direction or discharge height, the operator only needs to change the length of the adjusting rod 403. Shortening the adjusting rod 403 will pull the tail of the second bracket 402 downward, making its inclination angle gentler; extending the adjusting rod 403 will push the tail of the second bracket 402 upward, making its inclination angle steeper. After adjusting to the predetermined angle, the adjusting rod 403 can be locked. In this way, the inclination angle and direction of the discharge belt conveyor 12 are accurately and reliably fixed, ensuring that the sand is efficiently and accurately transported to the designated position, effectively avoiding problems such as material accumulation, spillage, or belt deviation caused by improper discharge angle.

[0029] Deep groove guard plates 8 are fixedly connected to both sides of the conveyor belt on the feeding rack 3 and the discharging rack 4. The deep groove guard plates 8 can form a deeper groove cross section together with the conveyor belt, effectively limiting the spillage of materials (especially fine-particle, highly fluid sand) from both sides of the belt during the conveying process. This significantly reduces material loss and environmental pollution, improves conveying efficiency, and maintains the cleanliness of the work site.

[0030] Secondly, both the feeding conveyor belt 11 and the discharging conveyor belt 12 are equipped with several idler rollers 9 and cleaning rollers 10. Multiple sets of idler rollers 9 (including parallel idler rollers 9 and trough idler rollers 9) support the conveyor belt, reduce running resistance, and form a trough shape to increase conveying capacity. The cleaning rollers 10 (usually polyurethane scrapers or rotary brushes) are installed near the head roller of the conveyor belt to remove residual material adhering to the working surface of the conveyor belt, preventing belt wear and material backflow, effectively extending the service life of the equipment, and maintaining stable operation.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
