Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a cleaning device for a cylindrical drill bit of a rotary drilling rig. Background Technology

[0002] A rotary drilling rig, also known as a rotary drilling machine or pile drilling rig, is a type of mechanical equipment used in building foundation engineering for deep foundation construction. It excavates soil by rotating a cylindrical drill bit at the bottom, bringing the excavated soil out of the hole to form the desired pile hole.

[0003] Traditional rotary drilling rigs require shaking the cylindrical drill bit or striking it with a hammer after drilling to dislodge the excavated material inside. However, this method of cleaning is too noisy and has a significant impact on nearby residents, so it needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cleaning device for the cylindrical drill bit of a rotary drilling rig, which has the effect of reducing noise pollution.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By setting up a collection bucket for the cylindrical drill bit and a cleaner that can reach into the cylindrical drill bit, the excavated soil inside the cylindrical drill bit can be cleaned up and down by reciprocating impact, which can quickly and completely remove the excavated soil inside the cylindrical drill bit, improve work efficiency, and at the same time minimize the noise generated during the cleaning process, reducing the impact on surrounding residents.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 , Figure 2 As shown, a cleaning device for a cylindrical drill bit of a rotary drilling rig includes a support frame 1, a collection bucket 2, a chute 3, a crossbeam 4, and a cleaner 5.

[0025] like Figure 1 , Figure 2 As shown, the support frame 1 is vertically installed on the ground, and the collection bucket 2 is vertically installed on the support frame 1, with a horizontal support plate 21 on the upper inner wall for vertically supporting the cylindrical drill bit. The chute 3 is connected to the lower end of the collection bucket 2, and a container for holding the slag can be placed below the chute 3 to achieve directional collection of the slag and reduce environmental pollution.

[0026] like Figure 1 , Figure 2 As shown, the crossbeam 4 is horizontally positioned inside the collection bucket 2 and is slidably connected to the collection bucket 2. The collection bucket 2 is equipped with a cylinder 22 that controls the horizontal reciprocating movement of the crossbeam 4. The inner wall of the collection bucket 2 is equipped with a scraper 23 that abuts against the outer wall of the crossbeam 4 to scrape off the slag adhering to the crossbeam 4, ensuring the smooth movement of the crossbeam 4.

[0027] like Figure 1 , Figure 2 As shown, the cleaner 5 is vertically mounted on the crossbeam 4. The cleaner 5 includes a cleaning tube 51, a cleaning rod 52, and a drive mechanism 6.

[0028] like Figure 1 , Figure 2 As shown, the cleaning pipe 51 is vertically mounted on the crossbeam 4, and the cleaning rod 52 is vertically slidably connected to the cleaning pipe 51 and can extend above the collection bucket 2, and is used to insert into the cylindrical drill bit. The upper end of the cleaning rod 52 is provided with an umbrella-shaped spike 53, which causes the soil under impact to scatter and slide off, ensuring the smooth sliding of the cleaning rod 52.

[0029] like Figure 1 , Figure 2 As shown, the drive mechanism 6 is disposed inside the cleaning tube 51 and is used to control the vertical sliding of the cleaning rod 52. The drive mechanism 6 includes a reducer 61, a crank 62, and a connecting rod 63.

[0030] like Figure 1 , Figure 2 As shown, the reducer 61 is installed inside the cleaning pipe 51, and the support plate 21 is equipped with a push-button switch 24 for pressing the cylindrical drill bit and controlling the opening and closing of the reducer 61. The crank 62 is installed on the reducer 61, and the connecting rod 63 is rotatably connected to the lower end of the crank 62 and the cleaning rod 52.

[0031] When it is necessary to clean the excavated soil inside the cylindrical drill bit, the cylindrical drill bit is placed vertically on the support plate 21 on the collection bucket 2, with the opening of the cylindrical drill bit facing downwards. At the same time, the cylindrical drill bit presses the button switch 24 on the support plate 21 to start, and the reducer 61 drives the crank 62 and connecting rod 63 to rotate synchronously. At this time, the connecting rod 63 drives the cleaning rod 52 and the spike 53 to move vertically back and forth, realizing the vertical impact of the excavated soil inside the cylindrical drill bit.

[0032] At the same time, the cylinder 22 is activated to control the horizontal reciprocating motion of the crossbeam 4, and the cleaner 5 moves horizontally and reciprocates while simultaneously impacting the cylindrical drill bit vertically, thus cleaning the slag inside the cylindrical drill bit from all directions. The cleaned slag is collected in the collection bucket 2 and discharged outward along the chute 3, achieving directional collection of slag.

[0033] After the tubular drill bit has finished cleaning, it resumes operation. At this time, the push-button switch 24 is reset, which causes the reducer 61 to stop, preparing for the next cleaning operation.

[0034] Therefore, by setting up a collection bucket 2 for holding the cylindrical drill bit and a cleaner 5 that can extend into the cylindrical drill bit, and by having the cleaner 5 move up and down and slide laterally, the slag inside the cylindrical drill bit can be quickly and completely removed, improving work efficiency. At the same time, the noise generated during the slag removal process is minimized, reducing the impact on surrounding residents.

[0035] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
