Description

Technical Field

[0001] This application relates to the technical field of electric compactors, and in particular to a device for preventing soil splashing in an electric compactor. Background Technology

[0002] The electric compactor is an important piece of equipment in civil engineering for determining the compaction characteristics of soil samples. It is widely used in geotechnical tests for projects such as roadbeds and embankments. Currently, the electric compactor mainly uses a motor to drive a compaction hammer to repeatedly hammer the soil sample to simulate the compaction process in actual engineering.

[0003] The existing announcement number CN207114276U, entitled "An Electric Compactor," describes a technical solution that includes a housing, a hammer mounted on the housing, and a drive mechanism mounted on the housing to move the hammer downwards. The drive mechanism includes a lifting motor for providing power and a control device electrically connected to the lifting motor. The control device includes: a sampling circuit for acquiring the three-phase drive voltage of the external power supply input to the lifting motor and outputting the converted three-phase sampling voltage; a detection circuit for detecting the phase sequence of the three-phase sampling voltage and outputting a detection signal based on the phase sequence; an execution circuit including a first controllable switch and a second controllable switch; and a control circuit for receiving the detection signal and controlling the closing of the first or second controllable switch based on the detection signal. This invention has the advantage of eliminating the need for manual detection of the external power supply phase sequence, thus facilitating operation.

[0004] Regarding the aforementioned technologies, the inventors discovered that during the compaction test, the lack of components to prevent soil sample splashing caused the compaction hammer to drop loose soil samples with low moisture content, resulting in soil sample loss, affecting the height of the soil sample after hammering, and leading to a decrease in soil sample compaction accuracy. Utility Model Content

[0005] In order to overcome the lack of components to prevent soil sample splashing in the existing compaction test process, the compaction hammer will shake loose soil samples with low moisture content out of the compaction cylinder, causing soil sample loss, affecting the soil sample height after hammering, and reducing the soil sample compaction accuracy, this application provides a soil splash prevention device for an electric compactor.

[0006] The technical solution for the anti-splashing device of the electric compactor provided in this application is as follows:

[0007] An anti-splash device for an electric compactor includes a support, a compaction component, and a drive component. The support includes a base and a material container. The material container is vertically mounted on the top surface of the base, and the top of the material container is open. Multiple support columns are vertically fixed on the bottom surface of the base. An observation window is fixed through the outer wall of the material container, and multiple scale lines are vertically formed on the observation window. The compaction component includes a cloth sleeve, a compaction rod, and a compaction hammer. The bottom surface of the cloth sleeve is open, and a connecting frame plate is horizontally fixed at the opening of the cloth sleeve. The connecting frame plate is fixed to the material container. At the top of the barrel, a screw cylinder is vertically fixed to the top surface of the cloth cover, and a compaction rod is inserted through the screw cylinder of the cloth cover. A compaction hammer is vertically fixed to the bottom end of the compaction rod, and an external thread is provided on the outer wall of the compaction rod. The external thread on the compaction rod is assembled and connected with the screw cylinder thread on the cloth cover. The driving component includes a rod frame and a hole frame. The rod frame is vertically fixed to the rear end face of the support, and a hole frame is vertically slidably assembled on the rod frame. The top end of the hole frame is connected to the top of the compaction rod. A hydraulic rod is vertically fixed to the top surface of the rod frame, and the output end of the hydraulic rod is fixed to the bottom surface of the hole frame.

[0008] By adopting the above technical solution, the material container is vertically inserted and fixed on the support during use. Then, soil samples are added to the material container. The bottom end of the cloth sleeve connecting frame plate of the compaction component is fixed to the top of the material container. When compacting, the hydraulic rod on the actuation rod extends, pushing the hole frame to slide vertically on the rod, which drives the compaction rod to move vertically downward, causing the compaction hammer at the bottom to fall and compact the soil sample in the material container. During compaction, the screw at the top of the cloth sleeve is fixed to the external thread of the compaction rod. When the compaction rod moves downward, it causes the cloth sleeve to extend and retract. When the soil sample is compacted, the soil sample splashes out of the material container. The splashed soil sample is blocked by the cloth sleeve, which effectively ensures that the soil sample in the material container does not splash, avoids soil sample loss, ensures the height of the soil sample after the hammer is used, and improves the compaction accuracy of the soil sample.

[0009] Optionally, a frame is vertically fixed to the bottom of the container, and multiple locking screws are assembled through the frame with vertical threads.

[0010] By adopting the above technical solution, in order to ensure the stability of the material container on the support during use, the material container is locked on the support by rotating multiple locking screws on the insertion frame.

[0011] Optionally, a mounting frame is fixed on the top surface of the support, and the mounting frame and the insert frame are slidably connected. The mounting frame has a screw groove, and the screw groove on the mounting frame is threadedly connected to the locking screw on the insert frame.

[0012] By adopting the above technical solution, in order to ensure the stability of the material container on the support, the mounting frame and the insert frame are slidably connected, and the locking screw on the insert frame is threaded through the mounting frame, thus ensuring the stability of the material container on the support.

[0013] Optionally, a perforated frame is horizontally fixed to the top of the material container, and the perforated frame is assembled with the connecting frame plate by bolts.

[0014] By adopting the above technical solution, the top hole frame of the material container and the connecting frame plate are fixedly assembled with bolts, and the connecting cloth is put on the top of the material container to prevent soil samples from splashing out of the material container.

[0015] Optionally, a sliding frame is vertically inserted through the top of the compaction rod, and the top of the sliding frame is fixed to the top surface of the hole frame.

[0016] By adopting the above technical solution, the top of the compaction rod is slidably inserted into the sliding frame, and the sliding frame is fixedly assembled with the top surface of the hole frame, which facilitates driving the hole frame to move the compaction rod vertically downward to compact the soil sample.

[0017] Optionally, a slider is rotatably connected to the top of the compaction rod, and the slider is vertically slidably assembled in the slide frame.

[0018] By adopting the above technical solution, the slider at the top of the compaction rod is vertically slidably assembled on the slide frame. When compacting the soil sample in the container, the impact force on the compaction rod is reduced when it is used to impact and compact the soil sample in the container.

[0019] Optionally, a damping spring is vertically fixed inside the upper side of the slide frame, and the bottom end of the damping spring is fixed to the top surface of the slider. A damping rod is vertically fixed to the top surface of the slider, and the top end of the damping rod is fixed to the top surface inside the slide frame.

[0020] By adopting the above technical solution, when the soil sample in the compaction bucket is impacted, in order to reduce the impact force on the compaction rod, the slider at the top of the compaction rod is vertically slidably assembled in the slide frame, which compresses the deformation of the shock-absorbing spring and the extension of the damping rod, thus filtering and reducing the impact force on the compaction rod. The deformation potential energy of the shock-absorbing spring is offset by the damping force of the damping rod.

[0021] Optionally, a return spring is vertically fixed to the lower side of the rod frame, and the top of the return spring is fixed to the bottom surface of the hole frame.

[0022] By adopting the above technical solution, the setting of the return spring facilitates the vertical sliding of the hole frame on the return rod in the later stage.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, the material container is vertically inserted and fixed on the support, and then a soil sample is added to the material container. Then, the bottom end connecting frame plate of the compaction component is fixed to the top of the material container. When compacting, the hydraulic rod on the starter rod extends, pushing the hole frame to slide vertically on the rod, causing the compaction rod to move vertically downward, causing the compaction hammer at the bottom to fall and compact the soil sample in the material container. When compacting, the screw at the top of the cloth sleeve is fixed to the external thread of the compaction rod. When the compaction rod moves downward, it causes the cloth sleeve to extend and retract. When the soil sample is compacted, the soil sample splashes out of the material container. The splashed soil sample is blocked by the cloth sleeve, which effectively ensures that the soil sample in the material container splashes out, avoids soil sample loss, ensures the height of the soil sample after the hammer is used, and improves the compaction accuracy of the soil sample.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a device for preventing soil splashing in an electric compactor. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4An electric compactor with anti-splashing device includes a support 1, a compaction component 2, and a drive 3. The support 1 includes a base 11 and a material container 13. The material container 13 is vertically assembled on the top surface of the base 11, and the top of the material container 13 is open. Multiple support columns 18 are vertically fixed on the bottom surface of the base 11. An observation window is fixed through the outer wall of the material container 13, and multiple scale lines 17 are opened vertically on the observation window of the material container 13. The compaction component 2 includes a cloth cover 21, a compaction rod 24, and a compaction hammer 242. The bottom surface of the cloth cover 21 is open, and a connecting frame plate 22 is horizontally fixed at the opening of the cloth cover 21. The connecting frame plate 22 is fixed to the top of the material container 13. A screw cylinder 23 is vertically fixed to the top surface of the cloth sleeve 21, and a compaction rod 24 is inserted through the screw cylinder 23 of the cloth sleeve 21. A compaction hammer 242 is vertically fixed to the bottom end of the compaction rod 24, and an external thread 243 is provided on the outer wall of the compaction rod 24. The external thread 243 on the compaction rod 24 is threadedly assembled with the screw cylinder 23 on the cloth sleeve 21. The driving component 3 includes a rod frame 31 and a hole frame 32. The rod frame 31 is vertically fixed to the rear end face of the support 11, and a hole frame 32 is vertically slidably assembled on the rod frame 31. The top end of the hole frame 32 is connected to the top of the compaction rod 24. A hydraulic rod 33 is vertically fixed to the top surface of the rod frame 31, and the output end of the hydraulic rod 33 is fixed to the bottom surface of the hole frame 32.

[0032] By adopting the above technical solution, the material container 13 is vertically inserted and fixed on the support 11 during use. Then, a soil sample is added to the material container 13. Then, the bottom end of the cloth sleeve 21 of the compaction component 2 is connected to the frame plate 22 and fixed to the top of the material container 13. When compacting, the hydraulic rod 33 on the starter rod 31 extends, pushing the hole frame 32 to slide vertically on the rod 31, driving the compaction rod 24 to move vertically downward, driving the compaction hammer 242 at the bottom to fall and compact the soil sample in the material container 13. When compacting, the screw cylinder 23 at the top of the cloth sleeve 21 is fixed to the external thread 243 of the compaction rod 24. When the compaction rod 24 moves downward, it drives the cloth sleeve 21 to extend and retract. When the soil sample is compacted, the soil sample splashes out of the material container 13. The splashed soil sample is blocked by the cloth sleeve 21, which effectively ensures that the soil sample in the material container 13 splashes, avoids soil sample loss, ensures the height of the soil sample after the hammer, and improves the compaction accuracy of the soil sample.

[0033] Reference Figure 3A frame 14 is vertically fixed to the bottom surface of the container 13, and multiple locking screws 15 are threaded through the frame 14. During use, to ensure the stability of the container 13 on the support 11, the multiple locking screws 15 on the frame 14 are rotated to lock the container 13 onto the support 11. A mounting frame 12 is fixed to the top surface of the support 11, and the mounting frame 12 is slidably inserted into the frame 14. The mounting frame 12 has threaded grooves, and these grooves are threadedly connected to the locking screws 15 on the frame 14. To ensure the stability of the container 13 on the support 11, the mounting frame 12 is slidably inserted into the frame 14, and the locking screws 15 on the frame 14 are threaded through the mounting frame 12, thus ensuring the stability of the container 13 on the support 11.

[0034] Reference Figure 1 A perforated frame 16 is horizontally fixed to the top of the material container 13, and the perforated frame 16 and the connecting frame plate 22 are assembled and fixed by bolts. The perforated frame 16 and the connecting frame plate 22 at the top of the material container 13 are assembled and fixed by bolts. A connecting cloth sleeve 21 is at the top of the material container 13 to prevent soil samples from splashing out of the material container 13.

[0035] Reference Figure 4 A sliding frame 25 is vertically inserted through the top of the compaction rod 24, and the top of the sliding frame 25 is fixed to the top surface of the borehole frame 32. The top of the compaction rod 24 is slidably inserted into the sliding frame 25, and the sliding frame 25 is fixedly assembled with the top surface of the borehole frame 32, which facilitates driving the borehole frame 32 to move the compaction rod 24 vertically downward to compact the soil sample. A slider 241 is rotatably connected to the top of the compaction rod 24, and the slider 241 is vertically slidably assembled in the sliding frame 25. The slider 241 at the top of the compaction rod 24 is vertically slidably assembled in the sliding frame 25, and when compacting the soil sample in the material container 13, it is used to reduce the impact force on the compaction rod 24 when impacting the soil sample in the material container 13. A damping spring 251 is vertically fixed inside the upper side of the sliding frame 25, and the bottom end of the damping spring 251 is fixed to the top surface of the slider 241. A damping rod 244 is vertically fixed to the top surface of the slider 241, and the top end of the damping rod 244 is fixed to the top surface inside the sliding frame 25. When the soil sample in the compaction bucket 13 is impacted, in order to reduce the impact force on the compaction rod 24, the slider 241 at the top of the compaction rod 24 is vertically slid in the sliding frame 25, compressing the deformation of the damping spring 251 and the extension of the damping rod 244, filtering and reducing the impact force on the compaction rod 24. The deformation potential energy of the damping spring 251 is offset by the damping force of the damping rod 244.

[0036] Reference Figure 5 A return spring 34 is vertically fixed to the lower side of the rod bracket 31, and the top of the return spring 34 is fixed to the bottom surface of the hole bracket 32. The return spring 34 is provided to facilitate the subsequent vertical sliding of the hole bracket 32 ​​on the rod bracket 31.

[0037] The implementation principle of the anti-splashing device for an electric compactor according to an embodiment of this application is as follows: During use, the material container 13 is vertically inserted and fixed on the support 11. To ensure the stability of the material container 13 on the support 11, the mounting frame 12 and the insertion frame 14 are slidably inserted. The locking screw 15 on the insertion frame 14 is threaded through and installed on the mounting frame 12, ensuring the stability of the material container 13 on the support 11. Then, soil samples are added to the material container 13. Then, the bottom end of the cloth sleeve 21 of the compaction component 2 is fixed to the top of the material container 13. The top hole frame 16 of the material container 13 and the connecting frame plate 22 are fixed together by bolts. The connecting cloth sleeve 21 is at the top of the material container 13 to prevent soil samples from splashing out of the material container 13. When compacting, the hydraulic rod 33 on the starting rod 31 extends. The expansion mechanism pushes the hole frame 32 to slide vertically on the rod frame 31, causing the compaction rod 24 to move vertically downward, which in turn causes the compaction hammer 242 at the bottom to fall and compact the soil sample in the container 13. When the compaction rod 24 moves downward, the top screw 23 of the cloth sleeve 21 is fixed on the external thread 243 of the compaction rod 24. When the compaction rod 24 moves downward, it causes the cloth sleeve 21 to extend and retract. When it impacts and compacts the soil sample in the container 13, in order to reduce the impact force on the compaction rod 24, the slider 241 at the top of the compaction rod 24 is vertically slid and assembled in the sliding frame 25, which compresses the deformation of the shock-absorbing spring 251 and the extension of the damping rod 244, filtering and reducing the impact force on the compaction rod 24. The deformation potential energy of the shock-absorbing spring 251 is offset by the damping force of the damping rod 244. When the soil sample is compacted, the soil sample splashes out of the container 13, and the splashed soil sample is blocked by the cloth sleeve 21.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
