Abstract
Description
Technical Field
[0001] This utility model relates to the field of geotechnical exploration technology, specifically a crushing device for geotechnical exploration. Background Technology
[0002] Geotechnical engineering investigation refers to the activities of investigating, analyzing, and evaluating the geological and environmental characteristics and geotechnical engineering conditions of a construction site according to the requirements of a construction project, and preparing investigation documents. The task of geotechnical engineering investigation is to accurately reflect the engineering geological conditions of the site and the influence of the properties of the soil and rock mass according to the requirements of different investigation stages, and to conduct technical demonstration and evaluation in conjunction with the specific requirements of engineering design, construction conditions, and foundation treatment.
[0003] For example, the crushing device disclosed in Chinese authorized patent CN221558491 U is a crushing device for rock and soil exploration, which can automatically crush rock and soil, greatly reducing the workload of researchers and improving exploration efficiency.
[0004] The inventors believe that the above-mentioned device still has at least the following shortcomings that need to be improved. First, the main power of the drill rod comes from the elastic potential energy of the spring, and a complete energy storage and deformation recovery requires a time cycle. In other words, the operation of the drill rod is intermittent. At the same time, the spring is prone to fatigue during the long-term energy storage and deformation recovery process, and the force it generates will gradually decrease. Overall, the breaking effect of the device is limited. Second, the device generates a lot of noise and dust, which is detrimental to the health of the workers. Utility Model Content

[0024] 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.
[0025] like Figure 1-2 As shown, this utility model provides a technical solution: a crushing device for rock and soil exploration, including a shell 1, a handle 2 and a support rod 3 respectively provided at the bottom of the shell 1, the shell 1, the handle 2 and the support rod 3 form a triangular structure, the triangular structure has good stability and a more secure grip, and the handle 2 and the support rod 3 are respectively wrapped with a sponge sleeve 4, the sponge sleeve 4 can reduce vibration and recoil.
[0026] like Figure 1-2 As shown, a drill sleeve 5 is provided on one side of the housing 1. The drill sleeve 5 includes a sleeve opening 51 and a shock-absorbing part 52. The sleeve opening 51 is made of metal material, and the shock-absorbing part 52 is made of rubber material, which serves to absorb shock.
[0027] like Figure 3 As shown, a dust suction port 17 is provided inside the shock-absorbing part 52, and a vacuum cleaner 15 is provided on the outside of the housing 1. The vacuum cleaner 15 and the dust suction port 17 are connected by a vacuum suction pipe 16.
[0028] like Figure 3-4 As shown, a slide rod 6 is provided at the front and rear of the housing 1 at the same level as the drill sleeve 5. A rotatable lead screw 7 is provided below the slide rod 6. The lead screw 7 is driven by an external first motor 8. A slidable seat 9 is threaded onto the lead screw 7. The seat 9 is slidably mounted on the slide rod 6. The seat 9 can operate stably under the dual control of the slide rod 6 and the lead screw 7.
[0029] like Figure 3 As shown, a second motor 10 is provided on the top of the base 9, and a drill rod 11 is installed at the output end of the second motor 10. The drill rod 11 can freely enter and exit the drill sleeve 5.
[0030] like Figure 3 As shown, a controller 12 (including control circuit and battery compartment, etc., which are existing technologies and will not be described in detail) is provided at the bottom of the inner cavity of the housing 1. A switch panel 13 and a heat dissipation window 14 are provided on the outer side of the housing 1. The purpose of the heat dissipation window 14 is to dissipate heat for the second motor 10. The switch panel 13 includes a first switch button 131, a second switch button 132, and a third switch button 133 (which control the first motor 8, the second motor 10, and the vacuum cleaner 15, respectively).
[0031] like Figure 3 As shown, the inner wall of the housing 1 is provided with a sound insulation layer 18, which can be made of sound insulation cotton to reduce noise.
[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0033] When in use, the operator holds the handle 2 with one hand and the support rod 3 with the other, then finds the drilling point, places the drill sleeve 5 against the drill opening position, turns on the switch button 131, starts the first motor 8, drives the lead screw 7 to rotate, thereby driving the seat 9 and drill rod 11 to the position of the drill sleeve 5.
[0034] Then, turn on switch button 132 to start the second motor 10, which drives the drill rod 11 to rotate. Under the dual drive of the first motor 8 and the second motor 10, the drill rod 11 begins to advance along the drilling point to achieve the task of breaking the rock and soil layer. Since the drill rod 11 can advance automatically, it can save physical strength on the one hand, and the recoil is small on the other hand, making it more comfortable to operate.
[0035] During the crushing process, turn on switch button 3133 to start the vacuum cleaner 15. The vacuum cleaner 15 will absorb the dust generated during the crushing process through the suction port 17 to prevent dust from polluting the environment and harming human health.
[0036] After crushing is completed, the drill rod 11 is retracted into the housing 1 by the first motor 8 for easy carrying and storage.
[0037] In summary, the breaking device used in this geotechnical investigation has been improved upon by replacing the traditional fixed drill bit with a telescopic drill bit. The advantages of this telescopic drill bit include energy saving, automatic drill advance, low reaction force, and greater comfort. Furthermore, the telescopic drill bit can be stored in its housing when not in use for easy portability. Compared to the comparison document, it has greater drilling force, better continuity, and superior breaking effect. Moreover, by incorporating a sound insulation layer and a dust extraction mechanism, the noise and dust dispersion of the device can be reduced, minimizing harm to human health.
