Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a soil-breaking device for quality inspection of water conservancy projects. Background Technology
[0002] In water conservancy projects, it is necessary to conduct quality inspections on the excavated pits. Therefore, it is necessary to break ground at the construction site of the water conservancy project to facilitate the acquisition of soil samples or related testing.
[0003] A soil-breaking device for quality inspection of water conservancy projects, disclosed in Chinese Patent Publication No. CN219887000U, allows a rotating drill bit to break through different types of soil by means of a hydraulic cylinder, a first motor, and a drill bit, facilitating subsequent soil quality inspection. However, according to soil-breaking devices and existing technologies in related fields, for harder soil layers, relying solely on the rotating cutting of the auger drill bit has relatively weak breaking capacity, making it difficult to break through the soil quickly and effectively. It may take a long time to reach the required depth for inspection, affecting work efficiency. Furthermore, when encountering soil layers containing stones or other hard objects, the auger drill bit is prone to jamming or even damage due to excessive force, leading to interruption of the soil-breaking work. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a soil breaking device for quality inspection of water conservancy projects.
[0005] The purpose of this utility model is achieved through the following technical solution: a soil-breaking device for quality inspection of water conservancy projects, including a driving device, the output end of which is provided with a soil-breaking component; the soil-breaking component includes a spiral drill bit, multiple supports are fixedly installed on the spiral drill bit, and each of the multiple supports is equipped with an impact head, and the support is provided with a snap-fit component for convenient replacement of the impact head; the top end of the spiral drill bit is fixedly installed on the output end of the driving device.
[0006] Preferably, the support has an insertion hole for inserting the impact head, and the outer surface of the impact head inside the support has a snap-fit groove.
[0007] Preferably, the support has an installation groove corresponding to the snap-fit groove, the snap-fit assembly includes multiple snap-fit members adapted to the snap-fit groove, one end of each snap-fit member is rotatably disposed inside the installation groove, the inside of the installation groove is rotatably provided with a knob, the inner wall of the knob is fixedly provided with multiple teeth corresponding to the position of the snap-fit member, and each snap-fit member has multiple meshing grooves adapted to the teeth.
[0008] Preferably, all of the multiple snap-fit components are rotatably disposed inside the mounting groove via an elastic element shaft. The elastic element shaft includes a cylinder fixed to one end of the snap-fit component, a spring fixedly provided on the inner wall of the cylinder, a rotation hole provided at one end of the support located on the cylinder, and the end of the spring away from the cylinder being fixedly connected to the rotation hole.
[0009] Preferably, the end of the snap-fit component that mates with the snap-fit groove has an arc surface.
[0010] Preferably, the knob is connected to the mounting groove via a bearing, and the shaft is connected to the rotating hole via a bearing.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This soil-breaking device for quality inspection of water conservancy projects, by setting up soil-breaking components and clamping components, firstly, as the auger drill bit advances, it impacts and breaks up the soil. The impact force of the impact head can effectively break up relatively hard soil layers. Combined with the rotational cutting of the auger drill bit, the two work together to greatly improve the soil-breaking efficiency compared with a simple auger drill bit. Secondly, it can quickly replace the impact head, avoiding the impact of impact head damage on the progress of soil-breaking work, while also extending the service life of the entire soil-breaking device and reducing maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.
[0026] like Figures 1 to 10 As shown, a soil-breaking device for quality inspection of water conservancy projects is installed on an excavator 1. A drive device 2 is installed on the boom of the excavator 1, and a soil-breaking component 3 is provided at the output end of the drive device 2. The soil-breaking component 3 includes a spiral drill bit 31, and multiple supports 32 are fixedly installed on the spiral drill bit 31. Each of the multiple supports 32 is equipped with an impact head 33, and the supports 32 are provided with a snap-fit component 4 for easy replacement of the impact head 33. The top end of the spiral drill bit 31 is fixedly installed at the output end of the drive device 2.
[0027] like Figures 2 to 6As shown, the support 32 has an insertion hole 321 for inserting the impact head 33. The impact head 33 has a snap-fit groove 331 on its outer surface inside the support 32. The auger drill bit 31 can cut and break the soil when it rotates. The arrangement of multiple impact heads 33 can impact and break the soil as the auger drill bit 31 advances during rotation. The impact force of the impact head 33 can effectively break the harder soil layer. Combined with the rotation and cutting of the auger drill bit 31, the two work together to greatly improve the soil breaking efficiency compared to the simple auger drill bit 31.
[0028] like Figures 6 to 9 As shown, the support 32 has an installation groove 322 at the position corresponding to the snap-fit groove 331. The snap-fit assembly 4 includes multiple snap-fit pieces 41 that are adapted to the snap-fit groove 331. One end of the snap-fit piece 41 that mates with the snap-fit groove 331 is formed with an arc surface. One end of the snap-fit piece 41 is rotatably disposed inside the installation groove 322. A knob 42 is rotatably disposed inside the installation groove 322 (the knob 42 is connected to the installation groove 322 through a bearing, and the knob 42 is embedded in the inner wall of the bearing). Multiple teeth 43 are fixedly disposed on the inner wall of the knob 42 at the position corresponding to the snap-fit piece 41. Each snap-fit piece 41 has multiple meshing grooves 44 that are adapted to the teeth 43.
[0029] like Figures 6 to 10 As shown, multiple snap-fit components 41 are rotatably mounted inside the mounting groove 322 via an elastic element shaft 5. The elastic element shaft 5 includes a cylinder 51 fixed to one end of the snap-fit component 41, a spring 52 fixedly mounted on the inner wall of the cylinder 51, and a rotating hole provided at one end of the support 32 located on the cylinder 51. The end of the spring 52 away from the cylinder 51 is fixedly connected to the rotating hole. The cylinder 51 is connected to the rotating hole via a bearing. When the impact head 33 needs to be replaced, the knob 42 is rotated, and the engagement between the gear 43 and the meshing groove 44 causes the multiple snap-fit components 41 to rotate synchronously around the cylinder 51 as the axis. (At this time, the spring 52 is in a twisted state.) After that, multiple snap-fit parts 41 will disengage from the snap-fit groove 331. At this time, the impact head 33 can be replaced. When the new impact head 33 is inserted into the insertion hole 321 of the support 32, the spring 52 will be restored by releasing the knob 42. This will cause multiple snap-fit parts 41 to rotate in opposite directions around the shaft cylinder 51 (when the snap-fit parts 41 rotate, the knob 42 will also rotate due to the cooperation between the meshing teeth 43 and the meshing groove 44). After that, multiple snap-fit parts 41 will enter the snap-fit groove 331, thereby completing the limiting of the snap-fit parts 41.
[0030] The work process is as follows:
[0031] S1, such as Figures 1 to 3As shown, when in use, the excavator 1 is started to reach the designated position, and then the drive device 2 is used to control the auger drill bit 31 to rotate, so that the boom of the excavator 1 controls the auger drill bit 31 to break through the soil layer.
[0032] S2, such as Figures 2 to 6 As shown, the auger bit 31 can cut and break the soil when it rotates. The multiple impact heads 33 can impact and break the soil as the auger bit 31 advances during its rotation. The impact force of the impact heads 33 can effectively break the harder soil layers. Combined with the rotational cutting of the auger bit 31, the two work together to greatly improve the soil breaking efficiency compared to the simple auger bit 31.
[0033] S3, such as Figures 4 to 10 As shown, when the impact head 33 needs to be replaced, the knob 42 is turned, and then the engagement between the meshing teeth 43 and the meshing groove 44 is used to make multiple snap-fit pieces 41 rotate synchronously around the shaft cylinder 51 (at this time, the spring 52 is in a twisted state). After that, the multiple snap-fit pieces 41 will disengage from the snap-fit groove 331, and the impact head 33 can be replaced at this time.
[0034] S4, such as Figures 4 to 10 As shown, when the new impact head 33 is inserted into the insertion hole 321 of the support 32, the spring 52, which was twisted, will return to its original state by releasing the knob 42, thereby causing multiple snap-fit parts 41 to rotate synchronously in opposite directions around the shaft cylinder 51 (when the snap-fit parts 41 rotate, the knob 42 will also rotate due to the cooperation between the meshing teeth 43 and the meshing groove 44). After that, multiple snap-fit parts 41 will enter the snap-fit groove 331, thereby completing the limiting of the snap-fit parts 41.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
