Description

Technical Field

[0001] This utility model relates to the technical field of soil sampling devices, specifically a soil sampling device for testing the compaction degree of sand filling. Background Technology

[0002] In the field of civil engineering, such as road construction and embankment projects, soil compaction is a key factor in ensuring project quality and stability. Therefore, accurate and rapid detection of soil compaction is of great significance for project quality control.

[0003] Currently, the common method for soil extraction is to place a mold at the location where soil needs to be extracted, and then use a round flat drill bit and a hammer to dig a pit in the through hole inside the mold to extract soil. This can create a relatively standard circular hole. However, it is not easy to limit the depth of the excavated hole, and it is difficult to ensure that the bottom of the hole remains horizontal. This can result in too much or too little soil being extracted, which in turn will affect the calculated data. Furthermore, the soil compacted by heavy rollers is very hard and has a high density, with the highest requirement being over 96%. Therefore, the excavation process is time-consuming and laborious, which is not conducive to improving work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a soil sampling device for sand filling test compaction degree to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil sampling device for sand filling test compaction degree, comprising an electric hammer and an extension plate, wherein the extension plate is located at the top of the electric hammer, a support assembly is installed inside the extension plate, and the support assembly is perpendicular to the extension plate, the support assembly includes a screw rod rotatably connected to the top of the outer wall of one side of the extension plate, a support frame is rotatably connected to one end of the screw rod, and two limiting rods are slidably inserted into the top of the outer wall of one side of the extension plate, one end of each of the two limiting rods is fixedly connected to the outer wall of one side of the support frame, the screw rod and the two limiting rods are perpendicular to the extension plate, and the support frame is parallel to the extension plate.

[0006] As a further preferred embodiment of this technical solution, the electric hammer and the extension plate are equipped with the same connecting assembly. The connecting assembly includes a connecting sleeve one and a connecting sleeve two sleeved on the outside of the electric hammer. One end of the connecting sleeve one and the connecting sleeve two is rotated by a hinge, and the other end of the connecting sleeve one and the connecting sleeve two is fixedly connected by bolts.

[0007] As a further preferred embodiment of this technical solution, the top of the outer circumferential wall of the connecting sleeve one is fixedly connected to one end of the extension plate, and the bottom of the connecting sleeve two is threadedly connected to the screw one. One end of the screw one is rotatably connected to the positioning block. An installation groove is opened on the inner circumferential wall of both the connecting sleeve one and the connecting sleeve two, and the positioning block fits into the inner wall of the installation groove.

[0008] A support can be attached to the outside of the electric hammer to limit the shovel body when it reaches a specified depth, ensuring that the bottom wall of the machined hole is at the same depth and remains horizontal, which helps improve data accuracy. The position of the support frame is adjusted according to the depth of the hole, and the lead screw is rotated by the extension rod, which will rotate and move upward along the extension plate. Since the support frame is rotatably connected to one end of the lead screw and is also fixedly connected to one end of two limit rods that are slidably inserted in the extension plate, the support frame is moved upward by the lead screw. Then, when it reaches the required height, the adjustment stops. When the electric hammer moves... After the shovel is inserted into the ground, as the depth increases, the support frame will contact the ground. Under its restriction, the position of the shovel cannot continue to descend. This process repeats to ensure that the bottom wall of the round hole is neither too deep nor too shallow. Before starting work, the position of the extension plate needs to be fixed. Turning the knob end of screw one will cause it to move along the connecting sleeve two towards the outer wall of the electric hammer. Since the positioning block is restricted by the mounting groove and will not rotate with screw one, it will be driven towards the electric hammer. Under the action of friction, the position of the connecting component and the extension plate will be fixed to prevent excessive movement from affecting the soil removal work.

[0009] As a further preferred embodiment of this technical solution, both of the mounting slots are rotatably connected to a plurality of equally spaced rollers, and a portion of each roller extends out of the mounting slot.

[0010] As a further preferred embodiment of this technical solution, the clamping device of the electric hammer holds a shovel rod inside, one end of which is fixedly connected to a shovel body, and the shovel body is set in a semi-circular arc surface.

[0011] As a further preferred embodiment of this technical solution, a marking assembly is installed inside the support frame. The marking assembly includes a slide rod fixedly connected inside the support frame, an mounting block slidably sleeved on the outside of the slide rod, the mounting block fitting against the inner wall of the support frame, a marking rod slidably inserted inside the mounting block, a spring sleeved on the outside of the marking rod, and a screw rod threadedly connected to the outer wall of one end of the mounting block, the screw rod fitting against the support frame.

[0012] Adjust the position of the marking rod according to the specifications of the soil sampling hole. Push the mounting block to one side, and it will slide along the sliding rod inside the support frame, thus changing the position of the marking rod. Then turn the two knobs on the screw, and it will press along the mounting block towards the support frame. Under the action of friction, the position of the mounting block will be restricted. Next, place the shovel on the ground, and press the top end of the marking rod to make it overcome the spring pressure and move along the mounting block towards the ground. Then push the marking rod to make a circular motion, thus forming a circular pattern on the ground. Soil can be sampled according to the pattern without the need for other tools.

[0013] As a further preferred embodiment of this technical solution, a scale line is provided on the outer wall of one end of the support frame, and the scale line is parallel to the slide rod and located on one side of the mounting block.

[0014] This utility model provides a soil sampling device for sand cone compaction testing, which has the following beneficial effects:

[0015] (1) This utility model, by setting a support component and a connecting component, can add a support component to the outside of the electric hammer, so that the shovel body will be restricted when it reaches the specified depth, thereby ensuring that the bottom wall of the machined round hole is at the same depth and maintains a horizontal state, which is conducive to improving the accuracy of the data. The position of the support frame is adjusted according to the depth of the round hole, and the lead screw is rotated by the extension rod. It will rotate and move upward along the extension plate. Since the support frame is rotatably connected to one end of the lead screw, and is also fixedly connected to one end of the two limit rods that are slidably inserted in the extension plate, the support frame will be driven by the lead screw to move upward horizontally. Then, when it reaches the required height, it will move upward. After stopping the adjustment, when the electric hammer drives the shovel body into the ground, as the depth increases, the support frame will contact the ground. Under its restriction, the position of the shovel body cannot continue to descend. By repeating this process, it can be ensured that the bottom wall of the round hole is neither too deep nor too shallow. Before starting work, the position of the extension plate needs to be fixed. Turn the knob end of screw one, and it will move along the connecting sleeve two towards the outer wall of the electric hammer. Since the positioning block is restricted by the mounting groove and will not rotate with screw one, it will be driven towards the electric hammer. Under the action of friction, the position of the connecting component and the extension plate will be fixed to prevent them from moving too much and affecting the soil removal work.

[0016] (2) This utility model sets up a marking component, adjusts the position of the marking rod according to the specifications of the soil sampling hole, pushes the mounting block to one side, and it will slide along the sliding rod inside the support frame, and the position of the marking rod will also change. Then, turn the screw two knob end, and it will press along the mounting block towards the support frame. Under the action of friction, the position of the mounting block will also be restricted. Then, place the shovel body on the ground, press the top end of the marking rod, and make it overcome the spring pressure and move along the mounting block towards the ground. Then push the marking rod to make a circular motion, thus forming a circular pattern on the ground. Soil can be taken according to the pattern without the need for other tools.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown in this embodiment, a soil sampling device for sand filling test compaction degree includes an electric hammer 1 and an extension plate 4. The extension plate 4 is located at the top of the electric hammer 1. A support assembly 5 is installed inside the extension plate 4, and the support assembly 5 is perpendicular to the extension plate 4. The support assembly 5 includes a screw rod 501 rotatably connected to the top of the outer wall of one side of the extension plate 4. One end of the screw rod 501 is rotatably connected to a support frame 503. Two limiting rods 502 are slidably inserted into the top of the outer wall of one side of the extension plate 4. One end of each of the two limiting rods 502 is fixedly connected to the outer wall of one side of the support frame 503. The screw rod 501 and the two limiting rods 502 are perpendicular to the extension plate 4, and the support frame 503 is parallel to the extension plate 4.

[0024] like Figure 2 and Figure 3 As shown, the same connecting component 6 is installed between the electric hammer 1 and the extension plate 4. The connecting component 6 includes a connecting sleeve 1 601 and a connecting sleeve 2 602 sleeved on the outside of the electric hammer 1. One end of the connecting sleeve 1 601 and the connecting sleeve 2 602 rotates through a hinge, and the other end of the connecting sleeve 1 601 and the connecting sleeve 2 602 is fixedly connected by bolts.

[0025] The top of the outer circumference of the connecting sleeve 601 is fixedly connected to one end of the extension plate 4. The bottom of the connecting sleeve 602 is threaded with a screw 605. One end of the screw 605 is rotatably connected to a positioning block 606. Both the inner circumference of the connecting sleeve 601 and the connecting sleeve 602 are provided with an installation groove 603, and the positioning block 606 fits against the inner wall of the installation groove 603.

[0026] The position of the support frame 503 is adjusted according to the depth of the circular hole. The extension rod drives the lead screw 501 to rotate, causing it to move upwards along the extension plate 4. Since the support frame 503 is rotatably connected to one end of the lead screw 501 and also fixedly connected to one end of the two limit rods 502 that are slidably inserted into the extension plate 4, the support frame 503 is driven upwards by the lead screw 501. Adjustment stops when it reaches the desired height. When the electric hammer 1 drives the shovel body 3 into the ground, as the depth increases, the support frame 503 will contact the ground, preventing the shovel body 3 from descending further. This process is repeated. To ensure that the bottom wall of the circular hole is neither too deep nor too shallow, the position of the extension plate 4 needs to be fixed before work begins. Turning the knob end of the screw 605 will cause it to move along the connecting sleeve 602 toward the outer wall of the electric hammer 1. Since the positioning block 606 is restricted by the mounting groove 603 and will not rotate with the screw 605, it will be driven toward the electric hammer 1. Under the action of friction, the positions of the connecting component 6 and the extension plate 4 will be fixed to prevent excessive movement from affecting the soil removal work. If the position of the extension plate 4 needs to be adjusted, simply drive the positioning block 606 away from the outer wall of the electric hammer 1, and the adjustment can be easily made.

[0027] like Figure 3 As shown, multiple equally spaced rollers 604 are rotatably connected inside both mounting slots 603, and a portion of each roller 604 extends out of the mounting slot 603, which can convert sliding friction into rolling friction, thereby making the rotation of connecting sleeve one 601 and connecting sleeve two 602 convenient enough.

[0028] like Figure 1 As shown, the clamping device of the electric hammer 1 holds the shovel rod 2, and one end of the shovel rod 2 is fixedly connected to the shovel body 3, which is set in a semi-circular arc surface. When the electric hammer 1 drives the shovel rod 2 and the shovel body 3 to impact the ground, the shovel body 3 can be quickly inserted into the ground, thereby greatly improving the soil removal efficiency.

[0029] like Figure 2 and Figure 4 As shown, a marking assembly 7 is installed inside the support frame 503. The marking assembly 7 includes a slide rod 701 fixedly connected inside the support frame 503. An installation block 702 is slidably sleeved on the outside of the slide rod 701. The installation block 702 fits against the inner wall of the support frame 503. A marking rod 703 is slidably inserted inside the installation block 702. A spring 704 is sleeved on the outside of the marking rod 703. A screw 705 is threadedly connected to the outer wall of one end of the installation block 702. The screw 705 can fit against the support frame 503.

[0030] Adjust the position of the marking rod 703 according to the specifications of the soil extraction hole, push the mounting block 702 to one side, and it will slide along the slide rod 701 inside the support frame 503, thus changing the position of the marking rod 703. Then turn the knob end of the screw 705, and it will press along the mounting block 702 towards the support frame 503. Under the action of friction, the position of the mounting block 702 will also be restricted. Next, place the shovel body 3 on the ground, and press the top end of the marking rod 703 to make it overcome the pressure of the spring 704 and move along the mounting block 702 towards the ground. Then push the marking rod 703 to make a circular motion, thus forming a circular pattern on the ground. Soil can be extracted according to the pattern without the need for other tools.

[0031] like Figure 4 As shown, a scale line is provided on the outer wall of one end of the support frame 503, and the scale line is parallel to the slide rod 701 and located on one side of the mounting block 702. By referring to the scale line, more accurate adjustment can be ensured.

[0032] This utility model provides a soil sampling device for sand filling test compaction degree sampling, the specific working principle of which is as follows:

[0033] When the device is in operation, adjust the position of the marking rod 703 according to the specifications of the soil sampling hole. Push the mounting block 702 to one side, and it will slide along the sliding rod 701 inside the support frame 503, thus changing the position of the marking rod 703. Then, turn the knob end of the screw 705, and it will press along the mounting block 702 towards the support frame 503. Under the action of friction, the position of the mounting block 702 will also be restricted. Then, place the shovel body 3 on the ground and press down on the top end of the marking rod 703. This allows it to overcome the pressure of the spring 704 and move along the mounting block 702 towards the ground. Pushing the marking rod 703 then allows for circular motion, forming a circular pattern on the ground. Soil can be collected simply by following the pattern, without the need for other tools. Next, the position of the support frame 503 is adjusted according to the depth of the circular hole. The extension rod drives the lead screw 501 to rotate, causing it to rotate and move upwards along the extension plate 4. Since the support frame 503 is rotatably connected to one end of the lead screw 501 and also slides into the extension plate 4... Two limiting rods 502 in the extension plate 4 are fixedly connected at one end, so the support frame 503 will be driven upward by the screw 501. Then, when it reaches the required height, the adjustment stops. When the electric hammer 1 drives the shovel body 3 into the ground, as the depth increases, the support frame 503 will contact the ground. Under its restriction, the position of the shovel body 3 cannot continue to descend. This process is repeated to ensure that the bottom wall of the round hole is not too deep or too shallow. Before working, the position of the extension plate 4 needs to be fixed. Turn the knob end of the screw 605, and it will move along the connecting sleeve 602 towards the outer wall of the electric hammer 1. Since the positioning block 606 is restricted by the mounting groove 603 and will not rotate with the screw 605, it will be driven towards the electric hammer 1. Under the action of friction, the position of the connecting component 6 and the extension plate 4 will be fixed to prevent them from moving too much and affecting the soil removal work. If the position of the extension plate 4 needs to be adjusted, simply drive the positioning block 606 away from the outer wall of the electric hammer 1. At this time, the adjustment can be easily made.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
