Description

Technical Field

[0001] The utility model relates to the technical field of earth backfill measurement, in particular to an earth backfill compaction measurement device. Background Art

[0002] In the process of measuring the compaction degree of earthwork backfill, it is necessary to use the pit digging and sand filling method to measure the compaction degree. When using the pit digging and sand filling method, the looseness and dryness of the measured sand must be accurate, and debris must be removed and dried. For example, the patent with publication number CN210269839U discloses a soil backfill compaction degree measuring device, including a device housing, a motor protection cover is installed in the middle of the top of the device housing, a motor is connected to the top of the motor protection cover, a motor is connected to the bottom of the motor, a fixed rod is fixedly connected to the bottom of the motor housing, a mesh cylinder is fixedly connected to the bottom of the fixed rod, a feed pipe and a discharge pipe are connected to the right side and the left side of the bottom of the mesh cylinder respectively, and a pipe cover is movably connected to one side of the feed pipe and the discharge pipe. The device generates centrifugal force by rotating the mesh cylinder, and the sand and gravel are thrown out and filtered through the mesh cylinder. However, since the measured sand is usually fine, using a mesh with a smaller mesh number will make drainage more difficult, while using a mesh with a larger mesh number will cause the fine sand to be lost, thereby wasting the measured sand.

[0003] To this end, the utility model provides an earth backfill compaction measuring device. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: an earth backfill compaction measuring device, comprising a shell 1, a sieve plate 6 is slidably fitted in the shell 1, a collecting box 7 is installed on one side of the shell 1, a conical guide plate 9 is installed in the shell 1, a guide plate 8 is slidably fitted in the shell 1, a cleaning cylinder 10 is fixed to the bottom of the shell 1, a drainage groove 13 is opened on the side of the cleaning cylinder 10, a baffle 12 is slidably fitted in the drainage groove 13, an auger dryer is installed on the lower side of the shell 1, and the auger dryer is connected to the cleaning cylinder 10.

[0022] In this embodiment, a first slide groove 2 and a first through groove 4 are provided in the outer shell 1, the first through groove 4 is connected with the first slide groove 2, the first through groove 4 and the first slide groove 2 both correspond to the sieve plate 6, the sieve plate 6 is relatively inclined and installed in the outer shell 1, the collecting box 7 is fixed with the outer shell 1, and the collecting box 7 is located on the lower side of the sieve plate 6, a second slide groove 3 and a second through groove 5 are provided in the outer shell 1, the second slide groove 3 is connected with the second through groove 5, the second slide groove 3 and the second through groove 5 both correspond to the guide plate 8, the conical guide plate 9 is fixed to the outer shell 1, and the conical guide plate 9 is located between the guide plate 8 and the sieve plate 6.

[0023] Specifically, when only the weighing sand needs to be screened, the sieve plate 6 is slid into the first chute 2, the guide plate 8 is slid into the second chute 3, and then the weighing sand is poured onto the sieve plate 6. The sieve plate 6 screens the weighing sand. The sieved weighing sand enters the conical guide plate 9, falls on the guide plate 8 after being guided by the conical guide plate 9, and then flows out from the second through groove 5. The larger particles pass through the guidance of the sieve plate 6 and enter the collecting box 7 from the first through groove 4, thereby realizing the screening of the weighing sand. A blocking plate can also be installed in the first through groove 4 to extend the screening time.

[0024] A water outlet 11 is provided on one side of the bottom of the shell 1 , and a feed opening 14 is provided on the lower side of the shell 1 . The feed opening 14 is connected to the auger dryer and the cleaning cylinder 10 , and a valve 16 is installed in the feed opening 14 .

[0025] Specifically, when the measuring sand needs to be cleaned, the guide plate 8 is slid out, and then the water pipe is inserted into the cleaning cylinder 10 through the second through groove 5. As the measuring sand passes through the conical guide plate 9 and enters the cleaning cylinder 10, water is passed through the water pipe to clean the measuring sand. As the water level rises until it overflows, the debris will overflow with the sewage and be discharged from the water outlet 11. When the cleaning is completed, after standing and settling for a certain period of time, the baffle 12 is slid downward to drain the water from the drain trough 13. After most of the water is discharged, the valve 16 can be opened to allow the measuring sand to enter the auger 15 for drying.

[0026] The auger dryer comprises an auger 15 , in which a resistance rod 17 is installed.

[0027] Specifically, after the measured sand enters the auger 15, the auger 15 pushes the measured sand spiral to move, thereby sending the measured sand out, and at the same time the resistance rod 17 heats and dries the measured sand.

[0028] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
