Description

Technical Field

[0001] This utility model relates to the technical field of erosion trench backfilling and compaction devices, and in particular to an auxiliary device for erosion trench backfilling and compaction. Background Technology

[0002] Gullies are gullies formed on the surface of the land due to soil erosion. The existence of gullies not only damages land resources, but may also trigger geological disasters such as landslides and debris flows, posing a serious threat to the ecological environment and human activities. Therefore, it is particularly important to effectively manage and restore gullies.

[0003] In the process of gully erosion control, backfilling and compaction is a crucial step. The main steps include excavating backfill trenches, laying drainage pipes, laying filter layers, backfilling soil, constructing filter walls, and burying straw. During backfilling, the soil needs to be backfilled in layers, and each layer requires compaction. Compaction is achieved using mechanical equipment, such as excavator compaction wheels, to compact soil, coal, silt, and pre-loosened soil and rock. To ensure proper compaction, the soil is usually moistened by spraying water. However, during the compaction process, some soil adheres to the compaction wheel, reducing the contact area between the wheel and the soil and thus decreasing the compaction effect. Furthermore, the sticky soil causes uneven weight distribution on the compaction wheel, further affecting the uniformity of compaction. Therefore, an auxiliary device for backfilling and compacting gullies is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary device for backfilling and compacting erosion trenches includes a crane frame, a compaction wheel movably installed below the crane frame, two plate assemblies installed on the left and right sides of the crane frame, and two cleaning accessories symmetrically installed on the front and back sides of the crane frame. Each cleaning accessory includes a suspension plate fixed to the narrow side of the crane frame, a plate frame connected to the bottom end of the suspension plate, and a rotating shaft rotatably connected inside the plate frame. A scraper is connected to the surface of the rotating shaft.

[0007] Preferably, the scraper surface is provided with a dividing blade, and the dividing blades are equidistantly arranged on the scraper surface. The dividing blades on the scraper surface can cut the scraped soil, so that the soil can fall quickly to the ground surface.

[0008] Preferably, a guide plate is bolted to the surface of the scraper near the pivot point. The guide plate can intercept the scraped clay and prevent some soil from splashing after scraping.

[0009] Preferably, the guide plate has a curved structure design, with the curved end of the guide plate facing downwards. The downward-facing curved end of the guide plate can guide the clay, allowing the scraped soil to move quickly to the ground surface during the guidance process.

[0010] Preferably, the shaft ends on both sides of the rotating shaft pass through the plate frame and are connected to a turntable. The surface of the turntable is provided with threaded holes, and locking bolts are inserted into the threaded holes. The side of the plate frame is provided with positioning holes that are compatible with the threaded holes of the turntable. The locking bolts pass through the turntable and are inserted into the positioning holes on the side of the plate frame to ensure the stability of the scraper after adjustment.

[0011] Preferably, the plate assembly includes a side hanging plate, which is fixed to the side of the crane frame by bolts. A dustproof plate is connected to the bottom end of the side hanging plate. The side hanging plate can protect the mating part of the compaction wheel side and prevent the mating part of the side from directly colliding and deforming with hard objects such as stones.

[0012] Preferably, the side panel is symmetrically connected to two barriers on the left and right sides, and the barriers are set at opposite inclinations. The design of the barriers can intercept some of the rising sand and soil.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting up a scraper, the soil adhering to the surface of the compaction wheel can be removed. This device drives the scraper to rotate through the rotating shaft, so that the distance between the end of the scraper and the surface of the compaction wheel can be adapted and adjusted. The scraper can scrape the soil on the surface of the rotating compaction wheel to ensure the compaction effect of the compaction wheel.

[0015] 2. By setting up a guide plate, the scraping of soil can be guided and splash-proofed. During the scraping process, the guide plate can guide the plate-shaped clay generated during scraping, so that the clay falls back to the ground surface along the arc surface of the guide plate, effectively preventing soil splashing.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-4 An auxiliary device for backfilling and compacting erosion trenches includes a crane frame 1, a compaction wheel 2 movably installed below the crane frame 1, two plate assemblies 3 installed on the left and right sides of the crane frame 1, and two cleaning accessories 4 symmetrically installed on the front and back sides of the crane frame 1. The cleaning accessories 4 include a suspension plate 41 fixed to the narrow side of the crane frame 1, a plate frame 42 connected to the bottom end of the suspension plate 41, and a rotating shaft 43 rotatably connected inside the plate frame 42. A scraper 44 is connected to the surface of the rotating shaft 43.

[0024] The scraper 44 has a dividing blade on its surface, and the dividing blades are evenly spaced on the surface of the scraper 44.

[0025] A guide plate 45 is bolted to the surface of the scraper 44 near the pivot 43.

[0026] The guide plate 45 has a curved structure design, and the curved end of the guide plate 45 faces downward.

[0027] The two ends of the rotating shaft 43 pass through the plate frame 42 and are connected to the turntable 46. The surface of the turntable 46 is surrounded by threaded holes, and locking bolts 47 are inserted into the threaded holes. The side of the plate frame 42 is provided with positioning holes that are compatible with the threaded holes of the turntable 46.

[0028] The plate assembly 3 includes a side hanging plate 31, which is fixed to the side of the crane frame 1 by bolts, and a dustproof plate 33 is connected to the bottom end of the side hanging plate 31.

[0029] The side panel 31 is symmetrically connected to two enclosures 32 on the left and right sides, and the enclosures 32 are set at opposite angles.

[0030] When the scraper 44 scrapes the soil off the surface of the compaction wheel 2, the cutting edge of the scraper 44 can cut the scraped soil, making it easy for the soil to fall quickly to the ground surface. The guide plate 45 can intercept the scraped clay to prevent some soil from splashing after scraping.

[0031] The curved end of the guide plate 45 faces downward to guide the clay, allowing the scraped soil to move quickly to the ground surface. After the rotating shaft 43 is rotated and adjusted, the rotating shaft 43 can synchronously drive the turntable 46 to rotate. After the turntable 46 is adjusted, the locking bolt 47 can be inserted through the turntable 46 and into the positioning hole on the side of the plate frame 42 to ensure the stability of the scraper 44 after adjustment.

[0032] The side mounting plate 31 protects the mating area on the side of the compaction wheel 2, preventing direct collision and deformation with hard objects such as stones, which would affect the later assembly and disassembly of the compaction wheel 2. The design of the enclosure 32 can intercept some of the rising sand and soil, and at the same time intercept the clay on the left and right sides of the compaction wheel 2.

[0033] Working principle: According to the appendix Figure 1 With appendix Figure 2 As shown, during use, the crane frame 1 connects with the boom of an excavator or other mechanical equipment, and the boom compacts the compaction wheel 2. Before compaction, the suspension plate 41 can be fixed to the side of the crane frame 1 according to the actual environmental conditions. Figure 3 With appendix Figure 4 As shown, the rotation of the shaft 43 can change the tilt angle of the scraper 44 and the distance between the end of the scraper 44 and the surface of the compaction wheel 2. The rotation of the shaft 43 can synchronously drive the turntable 46 to rotate. After the adjustment is completed, the scraper 44 can be fixed by inserting the end of the locking bolt 47 through the threaded hole of the turntable 46 into the positioning hole on the surface of the plate frame 42. When the compaction wheel 2 rolls down, the sticky soil on the surface of the compaction wheel 2 is scraped off by the scraper 44. The soil is guided by the guide plate 45 and falls back down, effectively preventing the clay from sticking back or splashing.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
