Description

Technical Field

[0001] This utility model relates to the field of volcanic rock sorting technology, and in particular to an embedded dynamic weighing separation screen. Background Technology

[0002] Volcanic rock is formed from the cooling and solidification of magma after a volcanic eruption. After processing through crushing and screening, it becomes manufactured sand or gravel. Sand and gravel made from volcanic rock can be used as building aggregates, possessing properties such as weather resistance and sound absorption, replacing traditional natural sand or asbestos products. Currently, embedded dynamic weighing separation screen equipment consists of a vibrating screen, electronic belt scale, and other structures.

[0003] Currently, the screen mesh on a vibrating screen is usually fixed with bolts and a fixed frame. However, during the operation of the vibrating screen, the vibration is directly transmitted to the bolts. Long-term vibration may cause the bolts to loosen, which requires the staff to frequently maintain and tighten the bolts, increasing the maintenance burden on the staff. Utility Model Content

[0004] Therefore, it is necessary to provide an embedded dynamic weighing separation screen to address the problems of high maintenance frequency and high workload associated with existing embedded dynamic weighing separation screens that use bolts to fix the screen.

[0005] An embedded dynamic weighing and separating screen includes: a hexagonal bolt, a nut, and an anti-loosening mechanism. The nut is threadedly connected to the shank of the hexagonal bolt, and a slot is provided on the outer side of the nut.

[0006] In one embodiment, the anti-loosening mechanism includes a regular hexagonal frame and a circular frame, which are respectively fitted onto the head of the hexagonal bolt and the outside of the nut. A positioning groove is provided on the inner side of the circular frame, and an anti-loosening block is engaged inside the positioning groove. A mounting frame that is inserted into the slot is slidably connected to the surface of the anti-loosening block. A spring that is always in a compressed state is provided between the mounting frame and the anti-loosening block.

[0007] In one embodiment, the local cross-sectional shape of the contact area between the anti-detachment block and the positioning groove is a right triangle, and the inclined surfaces of the anti-detachment block and the positioning groove both face the regular hexagonal frame.

[0008] In one embodiment, the positioning groove is shaped like a hollow, flat-topped cone, and the inner diameter of the positioning groove gradually narrows from the nut toward the regular hexagonal frame.

[0009] In one embodiment, the local cross-sectional shape of the connection between the anti-detachment block and the mounting frame is a matching rectangle, and the opening size of the mounting frame is smaller than the maximum size of the anti-detachment block inside the mounting frame.

[0010] In one embodiment, the cross-sectional shape of the mounting frame and the slot connection part is a matching U-shape, and the opening of the U-shaped cross-section of the mounting frame and the slot connection part is facing the axis of the nut.

[0011] In one embodiment, an installation cavity is provided on the outer side of the mounting frame, a guide frame is rotatably connected inside the mounting cavity, and a guide rod that is rotatably connected to the anti-detachment block is slidably connected to the inner side of the guide frame.

[0012] In one embodiment, the number of springs is two and they are symmetrically distributed on both sides of the guide frame, and the springs are made of rubber material.

[0013] Beneficial effects

[0014] The aforementioned embedded dynamic weighing separation screen forms a double lock through the inclined engagement of the positioning groove and the anti-detachment block, and the U-shaped cooperation between the mounting frame and the slot. This effectively prevents the hexagonal bolts and nuts from loosening during vibration, reducing the frequency of screen maintenance. Furthermore, the modular design allows for quick alignment of the screen and the pressure frame through the positioning port. Combined with the welding and fixing of the regular hexagonal frame and the circular frame, this enables convenient screen replacement and stable sealing, thereby improving screening efficiency.

[0015] By using a load cell to detect the weight of material per unit length in real time, and combining the belt speed signal from the speed sensor, the integrator calculates and outputs the instantaneous flow rate and cumulative weight, enabling continuous and accurate weighing of highly abrasive materials such as sand and gravel. The integrator automatically calibrates the zero point and range to eliminate errors caused by belt tension fluctuations or material accumulation, ensuring long-term stability of dynamic weighing. Data can be directly output through a display screen or communication interface. Attached Figure Description

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0029] The following is combined with Figures 1-5 This invention describes an embedded dynamic weighing and separating screen.

[0030] In one embodiment, the embedded dynamic weighing separation screen includes: a multi-layer linear vibrating screen, a waste conveyor belt, an electronic belt scale, and a connecting mechanism. The waste conveyor belt is positioned at the location where the multi-layer linear vibrating screen discharges unqualified materials, and the electronic belt scale is positioned at the location where the multi-layer linear vibrating screen discharges qualified materials. The waste conveyor belt and the electronic belt scale run in opposite directions, and the connecting mechanism is installed in the multi-layer linear vibrating screen.

[0031] Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the multi-layer linear vibrating screen mainly consists of a screen box, a vibrating motor, a replaceable screen structure, damping springs, and a base. The vibrating motor is symmetrically installed on both sides of the screen box, generating excitation force through eccentric blocks. The damping springs connect the screen box and the base, buffering vibration and maintaining stable operation of the equipment. The overall structure is compact and can meet the needs of continuous and efficient screening.

[0032] The replaceable screen structure includes an installation frame welded inside the screen box. The screen is laid on the inner side of the installation frame, and a mesh pad is laid on the top of the screen. A pressure frame is pressed against the two corners of the top of the mesh pad. The surface of the pressure frame and the inner side of the screen box are provided with evenly distributed and mutually aligned positioning openings. A regular hexagonal frame 310 and a circular frame 320 are welded to the opposite ends of the pressure frame and the screen box, respectively.

[0033] Working principle: When the vibratory motor is powered on, its eccentric block generates a directional excitation force, causing the screen box to reciprocate in a straight line. After the material enters the top screen through the feed inlet, it is continuously thrown up, dispersed, and moved forward under the action of vibration. Particles that meet the particle size requirements pass through the screen holes and fall into the lower layer, while oversized particles are discharged from the discharge outlet along the screen surface. Through multi-layer screen filtration, the material is ultimately accurately classified according to particle size.

[0034] like Figure 5 As shown, the electronic belt scale mainly consists of a conveyor frame, a weighing bridge, load cells, a speed sensor, and an integrator. The conveyor frame supports the belt movement, the weighing bridge is installed below the belt, and the load cells detect the material weight in real time; the speed sensor monitors the belt speed, and the data is transmitted to the integrator for dynamic calculation. The overall structure is robust and durable, suitable for the continuous weighing needs of highly abrasive materials such as sand and gravel.

[0035] Working principle: When the belt conveyor transports sand and gravel, the load cell detects the weight of the material per unit length, and the speed sensor simultaneously collects the belt speed signal. Both data are input into the integrator, which calculates the instantaneous flow rate and cumulative weight through integration. The integrator automatically calibrates its zero point and measuring range to ensure weighing accuracy. The final result can be output via a display screen or communication interface.

[0036] The connecting mechanism includes a hexagonal bolt 100, a nut 200 and an anti-loosening mechanism 300. The nut 200 is threaded to the shank of the hexagonal bolt 100, and a slot 210 is provided on the outer side of the nut 200.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the anti-loosening mechanism 300 includes a regular hexagonal frame 310 and a circular frame 320. The regular hexagonal frame 310 and the circular frame 320 are respectively fitted onto the head of the hexagonal bolt 100 and the outside of the nut 200. A positioning groove 321 is provided on the inner side of the circular frame 320. An anti-loosening block 330 is engaged inside the positioning groove 321. A mounting frame 340 that is inserted into the slot 210 is slidably connected to the surface of the anti-loosening block 330. A spring 350 that is always in a compressed state is provided between the mounting frame 340 and the anti-loosening block 330. The local cross-sectional shape of the contact part between the anti-loosening block 330 and the positioning groove 321 is a right-angled triangle. The inclined surfaces of the anti-loosening block 330 and the positioning groove 321 both face the regular hexagonal frame 310. The positioning groove 321 is hollow and flat-topped cone-shaped. The inner diameter of the positioning groove 321 extends from the nut 200 towards the regular hexagonal frame 310. The hexagonal frame 310 gradually narrows in direction; the local cross-sectional shape of the connection between the anti-detachment block 330 and the mounting frame 340 is a matching rectangle, and the opening size of the mounting frame 340 is smaller than the maximum size of the anti-detachment block 330 inside the mounting frame 340; the cross-sectional shape of the connection between the mounting frame 340 and the slot 210 is a matching U-shape, and the U-shaped cross-sectional openings of the connection between the mounting frame 340 and the slot 210 all face the axis of the nut 200; a mounting cavity 341 is provided on the outer side of the mounting frame 340, and a guide frame 360 ​​is rotatably connected inside the mounting cavity 341; a guide rod 370 that is rotatably connected to the anti-detachment block 330 is slidably connected on the inner side of the guide frame 360; there are two springs 350, which are symmetrically distributed on both sides of the guide frame 360, and the springs 350 are made of rubber material.

[0038] Working principle: During assembly, first, the shank of the hexagonal bolt 100 is passed sequentially through the regular hexagonal frame 310, the two interconnected positioning holes, and the circular frame 320 until its head is fully inserted into the regular hexagonal frame 310. Then, the mounting frame 340 is vertically inserted into the slot 210. At this time, the internal hexagonal socket sleeve matching the nut 200 is fitted onto the surface of the nut 200. During the downward pressing of the sleeve, the guide frame 360 ​​is simultaneously squeezed, forcing the guide rod 370 to drive the anti-disengagement block 330 back into the mounting frame 340. Next, the nut 200 is screwed into the shank of the hexagonal bolt 100. When the nut 200… When the nut 200 is tightly fitted to the outer wall of the screen box, the anti-detachment block 330 is precisely aligned with the positioning groove 321 of the circular frame 320. At this time, the inner hexagonal sleeve is removed, and the spring 350 immediately releases its elastic force to push the anti-detachment block 330 into the positioning groove 321 to complete the interlock. The final anti-loosening mechanism includes: the engagement of the circular frame 320 with the anti-detachment block 330 through the positioning groove 321, and the cooperation between the mounting frame 340 and the slot 210 to jointly constrain the displacement of the nut 200. At the same time, the hexagonal frame 310 limits the head of the hexagonal bolt 100. The double anti-loosening structure significantly improves the stability of the screen operation and reduces the frequency of maintenance.

[0039] It should be noted that the multi-layer linear vibrating screen, waste conveyor belt, and electronic belt scale mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the multi-layer linear vibrating screen, waste conveyor belt, and electronic belt scale are powered by mains power. The specific power supply method will be selected according to the situation and will not be elaborated here.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
