Description

Technical Field

[0001] The utility model relates to the technical field of earth breakers, in particular to an earth breaker for construction projects. Background Technique

[0002] Construction projects are a special type of construction activity organized by humans, aiming to build infrastructure and other structural buildings that people need. It is a general term for various buildings and engineering facilities that provide the material and technical basis for human life and production. It is mainly divided into three categories: building engineering, civil engineering, and mechanical and electrical engineering. An earth breaker is a commonly used device for ground leveling in construction project quality inspection.

[0003] According to the search, the Chinese patent document, publication number: CN216809836U, discloses an earth breaker for construction project quality inspection. By setting a support rod, a handle is fixedly connected to the top of the support rod. A double-headed threaded rod is arranged at the bottom of the outer wall of the support rod. An impact box is arranged at the bottom of the support rod and below the double-headed threaded rod. Pedal plates are fixedly connected to both sides of the outer wall of the impact box. In the utility model, by stepping on the pedal plates with feet, the earth-breaking collection head is inserted into the soil, so as to detect the quality of the construction project. When the soil is relatively hard, the double-headed threaded rod is rotated, so that the bottom of the double-headed threaded rod is threadedly connected to the outer wall of the ramming rod, so that the support rod has a certain moving space, which is convenient for the support rod to ram the support rod, so as to achieve the purpose of detecting the construction project. Under the action of the loose sleeve, lubrication is carried out between the ramming rod and the box body, reducing the wear of the ramming rod when ramming the support rod. However, this device has deficiencies. That is, the device uses a manual downward pressing method for earth breaking, with high labor intensity, heavy workload, and low efficiency. Moreover, the position of the handle in the device is fixed and cannot be adjusted, which is not user-friendly for workers with different heights and arm lengths, is not handy during work use, and has low work efficiency.

Embodiment

[0031] As Figure 1 , Figure 2 and Figure 3 shown, a ground-breaking device for construction projects provided by the present utility model includes a first fixing cylinder 1 with an open lower side. A second fixing cylinder 2 is fixedly installed at the upper end of the first fixing cylinder 1. A cover 3 is arranged at the lower end of the first fixing cylinder 1.

Handles 10 are symmetrically arranged at both ends of the second fixing cylinder 2, and adjusting grooves 11 are formed on both sides of the second fixing cylinder 2. A lifting and adjusting mechanism 9 for adjusting the height of the handles 10 is arranged in the second fixing cylinder 2.

[0032] Specifically, the drilling mechanism 6 includes a fixed ring 601, a first threaded rod 602, a first fixing plate 603, and a smooth rod 604. The fixed ring 601 is fixedly installed at the lower end inside the first fixed cylinder 1. The upper end of the right inner wall of the first fixed cylinder 1 is fixedly installed with the first fixing plate 603. A first threaded rod 602 is rotatably installed between the fixed ring 601 and the top wall of the first fixed cylinder 1. A smooth rod 604 is fixedly connected between the fixed ring 601 and the first fixing plate 603. The advantage is that the inner diameter of the fixed ring 601 is small, allowing the drill rod 5 to pass downward through it, and the first threaded rod 602 can rotate.

[0033] Specifically, the drilling mechanism 6 further includes a pushing ring 605. The pushing ring 605 is fixedly installed outside the first motor 4. The left end of the pushing ring 605 is threadedly connected to the outside of the first threaded rod 602, and the right end of the pushing ring 605 is movably sleeved on the outside of the smooth rod 604. The advantage is that when the first threaded rod 602 rotates, in cooperation with the smooth rod 604, it can drive the pushing ring 605 to move smoothly downward, thereby driving the first motor 4 to move downward, starting the first motor 4 to drive the drill rod 5 to rotate and drill into the soil.

[0034] Specifically, the drilling mechanism 6 further includes a first bevel gear 606, a second fixing plate 607, a second motor 608, and a second bevel gear 609. The first bevel gear 606 is fixedly installed on the outside of the upper end of the first threaded rod 602. The second fixing plate 607 is fixedly installed on the upper right inner wall inside the first fixed cylinder 1. The second motor 608 is fixedly installed on the second fixing plate 607. The second bevel gear 609 is fixedly installed on the output shaft of the second motor 608. The second bevel gear 609 is meshed and connected with the first bevel gear 606. The advantage is that starting the second motor 608 drives the second bevel gear 609 to rotate, the second bevel gear 609 drives the first bevel gear 606 to rotate, and thus the first bevel gear 606 drives the first threaded rod 602 to rotate. Embodiment

[0035] As Figure 3 and Figure 4 shown, as an improvement over the previous embodiment.

[0036] Specifically, the lifting and adjusting mechanism 9 further includes a lifting ring 904 and a connecting rod 905. The outer side of the second threaded rod 901 is threadedly connected with the lifting ring 904. Both ends of the lifting ring 904 are symmetrically and fixedly installed with connecting rods 905. The relatively far ends of the two connecting rods 905 pass through the adjusting slot 11 and are fixedly installed on the corresponding handle 10. The advantage is that when the second threaded rod 901 rotates, it drives the lifting ring 904 to move up and down, and drives the handle 10 to move up and down through the connecting rod 905, thereby adjusting the height of the handle 10, which is suitable for workers with different heights and arm lengths.

[0037] Specifically, an internal threaded ring 12 is fixedly installed on the inner bottom wall of the first fixed cylinder 1, and an external threaded ring 13 is fixedly installed on the upper end of the cover 3. The external threaded ring 13 is threadedly connected inside the internal threaded ring 12. The advantage is that the external threaded ring 13 is screwed into the internal threaded ring 12, so that the cover 3 seals the bottom opening of the first fixed cylinder 1 for sealing protection.

[0038] Specifically, multiple rows of anti-slip teeth 8 are fixedly installed on the upper end of the pedal 7, and an anti-slip sleeve 14 is fixedly sleeved on the outer side of the handle 10. The advantage is that the worker steps on the pedal 7 to apply a counterweight to the device. The anti-slip teeth 8 can prevent the sole from slipping. When the worker holds the handle 10 and pulls or pushes downward, a stable force is applied to the device. The anti-slip sleeve 14 can prevent the palm from slipping.

[0039] During use, first, the worker adjusts the height position of the handle 10 according to their physical conditions. Rotate the rotating cap 903 to drive the connecting column 902 to rotate. The second threaded rod 901 rotates to drive the lifting ring 904 to move up and down, and the connecting rod 905 drives the handle 10 to move up and down, so as to adjust the height of the handle 10 for use. Then the worker removes the cover 3 from the bottom of the first fixed cylinder 1, and then aligns and fits the bottom of the first fixed cylinder 1 on the land to be broken. Step on the pedal 7 to apply a counterweight to the device, hold the handle 10 and pull or push downward to keep the device stable. Then start the second motor 608 to drive the second bevel gear 609 to rotate. The second bevel gear 609 drives the first bevel gear 606 to rotate. The first bevel gear 606 drives the first threaded rod 602 to rotate, so as to cooperate with the smooth rod 604. The pushing ring 605 pushes the first motor 4 to move downward. Start the first motor 4 to drive the drill rod 5 to rotate. The drill rod 5 drills into the soil through the lower side of the first fixed cylinder 1.
