Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an earthwork backfilling and compaction machine for building construction. Background Technology

[0002] In building construction, compaction after backfilling is a key step in ensuring project quality. Its core purpose is to meet structural safety and functional requirements by increasing the density of the soil.

[0003] Announcement No.: CN220666178U includes a vehicle body and a mounting plate. A through groove is fixedly opened at the bottom of the vehicle body. A guide rod is fixedly connected to the top of the vehicle body. A sliding groove is fixedly opened at the bottom of the guide rod. Symmetrically arranged guide slots are fixedly opened inside the guide rod. Symmetrically arranged guide blocks are slidably connected inside each guide slot. Moving blocks are fixedly connected between each guide block. A two-way lead screw is rotatably connected near the top of the vehicle body. Symmetrically arranged connecting blocks are fixedly connected to the bottom of each moving block. Support rods are fixedly connected between each connecting block. Connecting rods are rotatably connected to each support rod. Symmetrically arranged C-shaped frames are fixedly connected to the top of the mounting plate. Pressure rods are fixedly connected to each C-shaped frame. This utility model uses mechanical transmission to drive the tamping hammer, which improves work efficiency and reduces manual labor intensity.

[0004] The aforementioned patent has some shortcomings: since the tamping hammer is located at the bottom of the vehicle body, the vehicle body blocks the tamping hammer from all sides. When tamping to the corner, if there is a wall or other obstacle blocking the way, there may be a situation where the corner is not tamped.

[0005] Therefore, this utility model designs an earthwork backfilling and compaction machine for building construction to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this utility model is to provide an earthwork backfilling and compaction machine for building construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a soil backfilling and compaction machine for building construction, comprising: a connecting plate, with movable wheels at all four corners of the bottom of the connecting plate, a U-shaped frame on one side of the connecting plate, a cylinder on the U-shaped frame via an adjustment component, a compaction plate at the output end of the cylinder, an air pump connected to the cylinder via a hose at the top of the connecting plate, a storage component on the connecting plate, a battery at the top of the connecting plate away from the U-shaped frame, and a controller on the battery. The U-shaped frame positions the compaction plate on one side of the connecting plate, preventing the compaction plate from being obstructed around its perimeter and ensuring that corners are not properly compacted.

[0008] Preferably, the adjusting component includes a lead screw, which is rotatably mounted between the two ends of the U-shaped frame. The outer wall of the lead screw is slidably mounted to one side of the slide block via a thread. The cylinder is mounted at the top center of the slide block. One end of the lead screw is connected to the output end of the drive motor. The drive motor drives the lead screw to rotate, which can cause the slide block to move back and forth laterally, thereby changing the position of the compaction plate and expanding the compaction range.

[0009] Preferably, a guide rod is fixedly installed between the two ends of the U-shaped frame, and the other side of the slide is slidably connected to the guide rod, which can guide the slide.

[0010] Preferably, the storage component includes a storage slot, which is located on one side of the connecting plate and slidably connected to the U-shaped frame. One side of the connecting plate has a groove 1 communicating with the storage slot, and one end of the connecting plate has a groove 2 communicating with the storage slot. An electric push rod is installed in the storage slot, and the output end of the electric push rod is fixedly installed on one side of the U-shaped frame. When not in use, the electric push rod drives the U-shaped frame to retract into the storage slot, the electric cylinder enters the groove 1, and the drive motor enters the groove 2, thereby reducing the overall footprint and making storage more convenient.

[0011] Preferably, a telescopic rod is installed in the storage slot, and one side of the telescopic rod is fixedly installed on one side of the U-shaped frame. The movement of the U-shaped frame causes the telescopic rod to extend and retract, and the telescopic rod plays a limiting role for the U-shaped frame.

[0012] Preferably, a U-shaped push rod is installed on the top side of the connecting plate, which facilitates the movement of the connecting plate by the operator.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention places the U-shaped frame on one side of the connecting plate, so that the compaction plate is on one side of the connecting plate, thus avoiding the connecting plate from blocking the compaction plate. Furthermore, the position of the compaction plate can be adjusted by the adjustment component, so that the compaction area is larger and the situation of insufficient compaction at corners is avoided.

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides an embodiment of an earthwork backfilling and compaction machine for building construction, comprising: a connecting plate 1, with movable wheels 2 at each of the four bottom corners of the connecting plate 1, a U-shaped frame 3 on one side of the connecting plate 1, a cylinder 5 on the U-shaped frame 3 via an adjusting component 4, a compaction plate 6 at the output end of the cylinder 5, an air pump 7 connected to the cylinder 5 via a hose at the top of the connecting plate 1, a storage component 8 on the connecting plate 1, a battery 9 at the top of the connecting plate 1 away from the U-shaped frame 3, a controller on the battery 9, and the compaction plate 6 being circular or square in shape.

[0021] Please see Figure 1-3 In this embodiment: the adjusting assembly 4 includes a lead screw 401, which is rotatably mounted between the two ends of the U-shaped frame 3. The outer wall of the lead screw 401 is slidably mounted to one side of the slide block 402 via a thread. The cylinder 5 is mounted at the top middle of the slide block 402. One end of the lead screw 401 is connected to the output end of the drive motor 403.

[0022] Please see Figure 1-3 In this embodiment: a guide rod is fixedly installed between the two ends of the U-shaped frame 3, and the other side of the slide block 402 is slidably connected to the guide rod.

[0023] Please see Figure 1-3 In this embodiment: the storage component 8 includes a storage slot 801, which is opened on one side of the connecting plate 1 and slidably connected to the U-shaped frame 3. A groove 802 communicating with the storage slot 801 is opened on one side of the connecting plate 1, and a groove 803 communicating with the storage slot 801 is opened at one end of the connecting plate 1. An electric push rod 804 is installed in the storage slot 801. The output end of the electric push rod 804 is fixedly installed on one side of the U-shaped frame 3. There are two electric push rods 804, which are respectively installed at both ends in the storage slot 801.

[0024] Please see Figure 1-3 In this embodiment: a telescopic rod 805 is installed in the storage slot 801, and one side of the telescopic rod 805 is fixedly installed on one side of the U-shaped frame 3.

[0025] Please see Figure 1-3 In this embodiment: a U-shaped push rod 10 is installed on one side of the top of the connecting plate 1.

[0026] Working principle: Air pump 7 supplies air to cylinder 5, which drives the tamping plate 6 to rise and fall to tamp the ground. Since the tamping plate 6 is located on one side of the connecting plate 1, the connecting plate 1 avoids obstructing the tamping plate 6 from all sides. At the same time, the rotation of the lead screw 401 causes the slide 402 to move laterally, which can increase the tamping range of the tamping plate 6. When not in use, the electric push rod 804 drives the U-shaped frame 3 to move into the storage groove 801, the cylinder 5 enters the first groove 802, and the drive motor 403 enters the second groove 803, which reduces the overall area occupied and facilitates storage. The contents not described in detail in this description are existing technologies known to those skilled in the art.
