Description

Technical Field

[0001] This utility model relates to the field of environmental engineering, specifically a soil backfilling and compaction device for environmental engineering. Background Technology

[0002] Building environmental engineering is a multidisciplinary field that involves the environment surrounding buildings, primarily focusing on the impacts of factors such as soil, groundwater, air quality, and noise on buildings and their surrounding environment. In building environmental engineering, soil backfilling and compaction equipment is a commonly used construction tool to improve soil density and stability. This equipment applies gravity or vibration to the soil, causing its particles to clump together tightly, increasing soil density and stability. This helps reduce uneven soil settlement and deformation, thereby ensuring the stability of the building.

[0003] The compaction equipment currently used works by pressing the soil down with a pressing plate to compact it. However, when encountering soil with high moisture content, the soil will stick to the pressing plate. When the pressing plate is lifted, some of the newly compacted soil will be carried away. The soil sticking to the pressing plate will cause the pressing plate to move with the soil. When the soil on the pressing plate reaches a certain thickness, it will disperse the compaction force, resulting in a decrease in compaction force and thus reducing the compaction effect.

[0004] Therefore, a soil backfilling and compaction device for environmental engineering is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems that soil sticking to the compaction plate causes the plate to move with the soil, and that when the soil on the plate reaches a certain thickness, it disperses the compaction force, resulting in a decrease in compaction force and thus reducing the compaction effect, this utility model proposes an environmental engineering soil backfilling and compaction device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The environmental engineering soil backfilling and compaction equipment of this utility model includes a machine body, a PLC control device fixedly connected to the top of the machine body, a handle fixedly connected to the outside of the machine body, two first rotating rods rotatably connected inside the machine body, the first rotating rods penetrating the machine body, and wheels fixedly connected to both ends of the first rotating rods. A scraping assembly is provided inside the machine body, the scraping assembly includes two mounting plates fixedly connected to the inside of the machine body, a sliding frame fixedly connected to the outside of the mounting plates, a scraper slidably connected inside the sliding frame, the scraper penetrating the sliding frame, a first sliding rod slidably connected inside the scraper, the first sliding rod fixedly connected inside the sliding frame, and a first spring fixedly connected between the scraper and the sliding frame.

[0007] Preferably, the machine body is provided with a pressing assembly, which includes a hydraulic cylinder fixedly connected to the top of the inner cavity of the machine body, a transmission frame fixedly connected to the bottom of the hydraulic cylinder, a transmission rod rotatably connected inside the transmission frame, a pressing frame fixedly connected to the outside of the transmission rod, a first support rod fixedly connected to the outside of the transmission rod, the end of the first support rod fixedly connected to the inside of the pressing frame, a first auxiliary support rod fixedly connected to the outside of the first support rod, and a second auxiliary support rod fixedly connected to the outside of the first auxiliary support rod, the ends of both the first and second auxiliary support rods being fixedly connected to the inside of the pressing frame.

[0008] Preferably, the pressing assembly further includes two sliders rotatably connected to both ends of the transmission rod, the outer side of the sliders being slidably connected to the inside of the machine body, the inside of the sliders being slidably connected to a second slide rod, the second slide rod being fixedly connected to the inside of the machine body, and a second spring being fixedly connected between the sliders and the machine body.

[0009] Preferably, a transmission assembly is provided on the outside of the transmission rod. The transmission assembly includes a gear chain fixedly connected to the outside of the transmission rod. The gear chain is fixedly connected to the outside of one of the first rotating rods. An auxiliary gear meshes with the outside of the gear chain. A limit rod is rotatably connected inside the auxiliary gear. The limit rod is fixedly connected inside the machine body.

[0010] Preferably, an auxiliary component is provided on the outside of the machine body. The auxiliary component includes two mounting blocks fixedly connected to the outside of the machine body, a second rotating rod fixedly connected between the two mounting blocks, and a push plate rotatably connected to the outside of the second rotating rod.

[0011] Preferably, the auxiliary component further includes a connecting thread formed inside the second rotating rod, and a nut is threaded onto the outer side of the connecting thread.

[0012] Preferably, the machine body is penetrated and slidably connected by a pressing frame, and the PLC control device is electrically connected to the hydraulic cylinder.

[0013] The advantages of this utility model are:

[0014] 1. This utility model utilizes the rotation of the pressing frame to allow the outer side of the pressing frame to slide against the outer side of the scraper, thereby pushing the scraper and compressing the first spring. The counterforce of the first spring ensures that the scraper remains on the outer side of the pressing frame, thus scraping off the soil adhering to the outer side of the pressing frame and returning the soil to the ground. This prevents a thick layer of soil from remaining on the pressing frame, ensuring that the compaction force is not dispersed and guaranteeing the compaction effect.

[0015] 2. This utility model allows the push plate to rotate by rotating the nut. After the end of the push plate comes into contact with the soil, the nut can be rotated again to fix the position of the push plate. This allows the device to move the push plate when it moves, thereby pushing away excess stones and other impurities. This ensures that stones will not affect the work during compaction, thus ensuring the efficiency and stability of the compaction work. Attached Figure Description

Detailed Implementation

[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] Example 1

[0026] Please see Figure 1-5 As shown, an environmental engineering soil backfilling and compaction device includes a body 1, a PLC control device 2 fixedly connected to the top of the body 1, a handle 3 fixedly connected to the outside of the body 1, two first rotating rods 4 rotatably connected inside the body 1, the first rotating rods 4 penetrating the body 1, and wheels 5 fixedly connected to both ends of the first rotating rods 4. A scraping assembly is provided inside the body 1, the scraping assembly includes two mounting plates 6 fixedly connected to the inside of the body 1, a sliding frame 7 fixedly connected to the outside of the mounting plates 6, a scraper 8 slidably connected inside the sliding frame 7, the scraper 8 penetrating the sliding frame 7, a first sliding rod 9 slidably connected inside the scraper 8, the first sliding rod 9 fixedly connected inside the sliding frame 7, and a first spring 10 fixedly connected between the scraper 8 and the sliding frame 7.

[0027] During operation, the rotation of the pressing frame 14 causes the outer side of the pressing frame 14 to slide against the outer side of the scraper 8, thereby pushing the scraper 8 and compressing the first spring 10. The counter-pushing force of the first spring 10 keeps the scraper 8 on the outer side of the pressing frame 14, thus scraping off the soil adhering to the outer side of the pressing frame 14 and returning the soil to the ground. This prevents the pressing frame 14 from having a thick layer of soil, ensuring that the pressing force is not dispersed and thus guaranteeing the compaction effect.

[0028] The machine body 1 is equipped with a pressing assembly, which includes a hydraulic cylinder 11 fixedly connected to the top of the inner cavity of the machine body 1. A transmission frame 12 is fixedly connected to the bottom of the hydraulic cylinder 11. A transmission rod 13 is rotatably connected inside the transmission frame 12. A pressing frame 14 is fixedly connected to the outside of the transmission rod 13. A first support rod 15 is fixedly connected to the outside of the transmission rod 13. The end of the first support rod 15 is fixedly connected to the inside of the pressing frame 14. A first auxiliary support rod 16 is fixedly connected to the outside of the first support rod 15. A second auxiliary support rod 17 is fixedly connected to the outside of the first auxiliary support rod 16. The ends of both the first auxiliary support rod 16 and the second auxiliary support rod 17 are fixedly connected to the inside of the pressing frame 14.

[0029] The pressing assembly also includes two sliders 18 rotatably connected to both ends of the transmission rod 13. The outer side of the sliders 18 is slidably connected to the inside of the body 1. A second slide rod 19 is slidably connected inside the sliders 18. The second slide rod 19 is fixedly connected to the inside of the body 1. A second spring 20 is fixedly connected between the sliders 18 and the body 1.

[0030] During operation, the hydraulic cylinder 11 pushes the transmission frame 12, which in turn drives the transmission rod 13 to move, thereby moving the slider 18, which in turn compresses the second spring 20, and causes the pressing frame 14 to contact the ground and press it, thereby compacting the soil.

[0031] By setting the first support rod 15, the first auxiliary support rod 16 and the second auxiliary support rod 17, the stability of the pressing frame 14 can be increased and the uniformity of the pressing force can be ensured.

[0032] The transmission rod 13 is provided with a transmission assembly on its outer side. The transmission assembly includes a gear chain group 21 fixedly connected to the outer side of the transmission rod 13. The gear chain group 21 is fixedly connected to the outer side of one of the first rotating rods 4. An auxiliary gear 23 meshes with the outer side of the gear chain group 21. A limit rod 22 is rotatably connected inside the auxiliary gear 23. The limit rod 22 is fixedly connected inside the machine body 1.

[0033] During operation, the rotation of wheel 5 drives the first rotating rod 4 to rotate, which in turn drives the gear chain assembly 21 to operate, which in turn drives the transmission rod 13 to rotate, thereby driving the pressing frame 14 to rotate, so as to facilitate the scraping of soil off the outside of the pressing frame 14.

[0034] The first rotating rod 4 can be divided into two sections, with a dual-head motor installed in the middle to provide power and control the moving distance, thereby facilitating the control of the rotation angle of the pressing frame 14 and improving the accuracy of the device.

[0035] The machine body 1 is penetrated and slidably connected by the pressing frame 14, and the PLC control device 2 is electrically connected to the hydraulic cylinder 11.

[0036] During operation, the pressing frame 14 is slidably connected to the body 1, which facilitates the compaction of the soil by the pressing frame 14.

[0037] Example 2

[0038] Please see Figure 6 As shown in the first embodiment, as another implementation of this utility model, an auxiliary component is provided on the outside of the body 1. The auxiliary component includes two mounting blocks 24 fixedly connected to the outside of the body 1, a second rotating rod 25 fixedly connected between the two mounting blocks 24, and a push plate 26 rotatably connected to the outside of the second rotating rod 25.

[0039] The auxiliary components also include a connecting thread 27 inside the second rotating rod 25, and a nut 28 is threaded onto the outer side of the connecting thread 27.

[0040] During operation, the push plate 26 can be rotated by turning the nut 28. When the end of the push plate 26 comes into contact with the soil, the nut 28 can be turned again to fix the position of the push plate 26. This allows the push plate 26 to move when the device moves, thereby pushing away excess stones and other impurities. This ensures that the stones will not affect the work during compaction, thus ensuring the efficiency and stability of the compaction work.

[0041] The working principle is as follows: the rotation of wheel 5 drives the first rotating rod 4 to rotate, which in turn drives the gear chain assembly 21 to operate, which in turn drives the transmission rod 13 to rotate, thereby driving the pressing frame 14 to rotate. This causes the outer side of the pressing frame 14 to slide against the outer side of the scraper 8, thus pushing the scraper 8 and compressing the first spring 10. The counter-pushing force of the first spring 10 keeps the scraper 8 on the outer side of the pressing frame 14, thereby scraping off the soil adhering to the outer side of the pressing frame 14 and returning the soil to the ground. This prevents the pressing frame 14 from having a thick layer of soil, thus preventing the compaction force from being dispersed and ensuring the compaction effect.
