Description

Technical Field

[0001] This utility model relates to the field of resource utilization technology of river and lake silt from water conservancy projects, and in particular to a connecting plate structure for an integrated treatment device for river, lake and reservoir silt. Background Technology

[0002] The dehydrated and solidified silt from rivers, lakes, and reservoirs contains large lumps (generally exceeding 20cm in diameter), hardened agglomerates (with a hardness exceeding 5MPa when the moisture content is below 30%), as well as mixed construction gravel (approximately 8-15%) and plastic waste (containing 3-8kg / m³). 3 Heterogeneous substances such as sediment are a key technical bottleneck in the current utilization of sludge resources. Existing technologies typically process sludge by crushing and screening it sequentially, facilitating its large-scale application in building materials manufacturing, roadbed materials, and agricultural production.

[0003] The crushing and screening of sludge typically rely on mobile crushers (sludge pulverizers) and electric screening machines, respectively. An electric screening machine is installed below the conveyor belt at the discharge end of the mobile crusher, allowing the crushed sludge to fall directly into the vibrating screen below for screening. For the crushed sludge to fall directly into the vibrating screen, the installation positions of the mobile crusher and the electric screening machine need to be precisely matched, which places high demands on the installation site and reduces operational flexibility.

[0004] To address this, a connecting plate structure for an integrated treatment device for river, lake, and reservoir silt is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-5 This utility model provides a connecting plate structure for an integrated treatment device for river, lake and reservoir silt, including a fixed receiving plate 1. The fixed receiving plate 1 is installed below the conveyor belt at the discharge end of the mobile crusher 2 to receive the crushed material transmitted from the conveyor belt of the mobile crusher 2. The fixed receiving plate 1 is inclined and the end away from the mobile crusher 2 is the low end.

[0027] An extension plate 3 is connected to the bottom of the fixed receiving plate 1 via a connecting frame 4. A telescopic drive assembly is provided on the fixed receiving plate 1. The telescopic drive assembly is connected to the connecting frame 4 to drive the connecting frame 4 to move along the length direction of the fixed receiving plate 1, thereby driving the extension plate 3 to extend or retract at the discharge end of the fixed receiving plate 1.

[0028] The extension plate 3 is rotatably connected to the connecting frame 4. The connecting frame 4 is equipped with an angle adjustment component. The angle adjustment component is connected to the extension plate 3 to drive the extension plate 3 to rotate, thereby adjusting the angle between the extension plate 3 and the fixed receiving plate 1. The discharge end of the extension plate 3 is located above the inlet of the electric screening machine 5.

[0029] The mobile crusher (mobile soil pulverizer) adopts the principle of a hammer crusher. Its specially designed blades can both cut and crush clay, and automatically discharge any hard objects it encounters. Its design integrates crushing and conveying, and it has tires for mobility, eliminating the need for a base and making it easy to move. The high-speed hammer crushing system is the core component, using high-speed rotating hammers to crush the material. The crushed material is then conveyed out via a conveyor belt (specific details are existing technology and will not be elaborated here).

[0030] An electric screening machine (vibrating screen) consists of four parts: a high-frequency vibrating motor, a primary fixed screen and a secondary grading fixed screen, vibrating springs, and a casing. The vibrating screen is an elastic vibration system, and its amplitude can be changed by the feed rate and other dynamic factors. The characteristics of the vibrating screen are high frequency, small amplitude, and the inclination of the screen surface is inversely proportional to the screening rate. The greater the inclination of the screen surface, the faster the flow velocity. The material jumps on the screen surface, resulting in higher productivity and screening efficiency (specific details are existing technology and will not be elaborated here). The crushed material falls onto the primary fixed screen of the electric screening machine for vibrating screening. Larger particles are screened out from the primary fixed screen, while smaller particles, such as soil, flow out from the discharge end of the secondary grading fixed screen.

[0031] In use, a fixed receiving plate 1 is installed below the conveyor belt at the discharge end of the mobile crusher 2. The extension length and tilt angle of the extension plate 3 at the discharge end of the fixed receiving plate 1 are adjusted so that the discharge end of the extension plate 3 is located above the inlet of the electric screening machine 5. This allows the crushed material to be conveyed to the fixed receiving plate 1 and then guided through the extension plate 3 to the inlet of the electric screening machine 5 for screening. This application achieves smooth docking between the mobile crusher 2 and the electric screening machine 5 by using the fixed receiving plate 1 and the extension plate 3 with adjustable extension length and tilt angle, reducing the requirements for the installation site and greatly improving the flexibility of use.

[0032] In some alternative embodiments, the telescopic drive assembly includes a first lead screw 6, which is located below the fixed receiving plate 1 and rotatably connected to the fixed receiving plate 1. A slide plate 7 is slidably connected below the fixed receiving plate 1. The first lead screw 6 passes through the slide plate 7 and is threadedly connected to the slide plate 7. The slide plate 7 is fixedly connected to the connecting frame 4. A first drive assembly that is driven by the first lead screw 6 is provided on the fixed receiving plate 1.

[0033] In some alternative embodiments, the first drive assembly includes a first motor 8 fixedly connected to one side of the fixed receiving plate 1, a first bevel gear 9 fixedly connected to the output shaft of the first motor 8, and a first lead screw 6 passing through the side wall of the fixed receiving plate 1 and fixedly connected to a second bevel gear 10, wherein the first bevel gear 9 meshes with the second bevel gear 10.

[0034] When adjusting the extension length of the extension plate 3, the first motor 8 drives the first bevel gear 9 to rotate, the first bevel gear 9 drives the second bevel gear 10 to rotate, causing the first lead screw 6 to rotate. The first lead screw 6 rotates with the slide plate 7, causing the slide plate 7 to slide back and forth along the length direction of the fixed receiving plate 1, thereby adjusting the extension length of the extension plate 3 on the connecting frame 4 at the discharge end of the fixed receiving plate 1.

[0035] In some optional embodiments, the end of the extension plate 3 is rotatably connected to the connecting frame 4 via the first rotating shaft 20. The two horizontal plates of the connecting frame 4 are respectively provided with long grooves 11. Support rods 12 are slidably connected on the long grooves 11. The two support rods 12 are respectively located on both sides of the extension plate 3. A connecting rod 13 is hinged between the support rod 12 and the side wall of the extension plate 3. The connection point of the connecting rod 13 and the support rod 12, the connection point of the connecting rod 13 and the extension plate 3, and the first rotating shaft 20 form a triangle. The tilt adjustment component is used to drive the support rod 12 to slide along the long groove 11.

[0036] By setting a triangular structure, when the support rod 12 slides in the long groove 11, the connecting rod 13 rotates, thereby pushing the extension plate 3 to rotate around the first rotating shaft 20 through the connecting rod 13, realizing the adjustment of the angle of the extension plate 3. The extension plate 3 plays the role of guiding the flow, which can guide the material on the fixed receiving plate 1 to the electric screening machine 5 for screening.

[0037] In some alternative embodiments, the tilt adjustment assembly includes a support block 14 fixed to the support rod 12, a second lead screw 15 threadedly connected to the support block 14, the second lead screw 15 passing through the support block 14, and a second drive assembly provided on the connecting frame 4, the second drive assembly driving the two second lead screws 15 to rotate.

[0038] In some alternative embodiments, the second drive assembly includes a second motor 16 fixed to the connecting frame 4, a second rotating shaft 17 fixed to the output shaft of the second motor 16, the second rotating shaft 17 being rotatably connected to the connecting frame 4, two third bevel gears 18 fixed to the second rotating shaft 17, and a fourth bevel gear 19 fixed to the end of the second lead screw 15 near the second rotating shaft 17, with the third bevel gears 18 meshing with the fourth bevel gear 19.

[0039] When adjusting the tilt angle of the extension plate 3, the second motor 16 drives the second rotating shaft 17 to rotate, which in turn drives the two third bevel gears 18 to rotate. The third bevel gears 18 drive the fourth bevel gear 19 to rotate, causing the second lead screw 15 to rotate. The second lead screw 15 rotates with the support block 14, which in turn drives the support rod 12 on the support block 14 to slide in the long groove 11, thereby realizing the adjustment of the angle of the extension plate 3.

[0040] In some alternative embodiments, baffles are fixed to both sides of the fixed receiving plate 1. The baffles protrude about 20cm in height to prevent materials from falling from both sides.

[0041] In some alternative embodiments, the fixed receiving plate 1 is welded to the bottom of the conveyor belt at the discharge end of the mobile crusher 2.

[0042] In use, the extension length and tilt angle of the extension plate 3 are adjusted according to the installation position and height of the mobile crusher 2 and the electric screening machine 5. When the extension length of the extension plate 3 is adjusted, the first motor 8 drives the first bevel gear 9 to rotate, the first bevel gear 9 drives the second bevel gear 10 to rotate, so that the first lead screw 6 rotates. The first lead screw 6 rotates with the slide plate 7, causing the slide plate 7 to slide back and forth along the length direction of the fixed receiving plate 1, thereby adjusting the extension length of the extension plate 3 on the connecting frame 4 at the discharge end of the fixed receiving plate 1.

[0043] When the tilt angle is adjusted, the second motor 16 drives the second rotating shaft 17 to rotate, which in turn drives the two third bevel gears 18 to rotate. The third bevel gears 18 drive the fourth bevel gear 19 to rotate, causing the second lead screw 15 to rotate. The second lead screw 15 rotates with the support block 14, which in turn drives the support rod 12 on the support block 14 to slide in the long groove 11. This, in turn, pushes the extension plate 3 to rotate around the first rotating shaft 20 through the connecting rod 13, thereby adjusting the angle of the extension plate 3. The extension plate 3 acts as a guide, guiding the material on the fixed receiving plate 1 to the electric screening machine 5 for screening.
