Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering, and relates to soil investigation, and in particular to a soil and rock sampling device for water conservancy and hydropower. Background Technology

[0002] Application CN202120245322.8 discloses a sampling device for soil and rock testing of foundations in water conservancy and hydropower projects. The technical solution is as follows: by setting up a micro electric pusher cylinder, when the soil inlet reaches the required soil and rock layer, the micro electric pusher cylinder is activated, which moves the U-shaped lifting plate away from the soil inlet, so that the soil inlet is connected to the installation hole, allowing the soil and rock to enter the installation hole from the soil inlet. Then, the micro electric pusher cylinder is activated again, which moves the U-shaped lifting plate down to block the soil inlet. This is to prevent soil and rock from other depths from entering when sampling soil and rock at different depths, so as not to affect the subsequent test data.

[0003] However, the above-mentioned existing technology has a drawback: the soil enters the rotating rod through the soil inlet, but it is not convenient to transfer the soil from the rotating rod to the storage container. Utility Model Content

[0004] This invention addresses the problem of difficulty in extracting soil and rock samples by providing a novel device that collects soil and rock samples using a soil collection trough and facilitates their extraction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a soil and rock sampling device for water conservancy and hydropower, comprising a body, the body including a drill pipe and a drill bit for insertion into soil and rock, a positioning plate fixedly connected inside the drill pipe, a miniature electric push rod fixedly connected to the upper side of the positioning plate, a transmission rod rotatably connected to the lower end of the miniature electric push rod passing through the positioning plate, a scraper rotatably connected to the end of the transmission rod away from the miniature electric push rod, a slide rail slidably connected to the upper end of the scraper, the slide rail being fixedly connected to the positioning plate, a first groove for the scraper to pass through on the side of the drill pipe corresponding to the scraper, scraping grooves on both sides of the scraper, a soil discharge hole at the bottom of the scraper, a soil collection groove below the scraper, and a second groove for the soil collection groove to pass through on the side of the drill pipe.

[0006] Preferably, the slide rail has an inverted T-shaped cross-section.

[0007] Preferably, the drill pipe is provided with several scrapers on its side for loosening the soil and rock.

[0008] Preferably, the side of the soil collection trough is connected to a protrusion, which is fixedly connected to the side of the drill pipe by bolts.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] The miniature electric push rod of this utility model can drive the scraper to move. After reaching the predetermined position, the scraper extends, and at the same time the drill pipe drives the scraper to rotate. The soil and rock can enter from the scraping groove on the side of the scraper and then enter the soil collection groove below. The soil collection groove can be pulled out from the second groove and is easy to fix.

[0011] The scraper of this invention can loosen the soil layer, making it easier for soil and rock to enter the scraper. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figure 1 , Figure 2As shown, a soil and rock sampling device for water conservancy and hydropower projects includes a main body in the prior art. The main body mainly includes a drill pipe 1 and a drill bit 2 for insertion into the soil and rock, as well as components such as a battery and a controller. The drill pipe 1 and the drill bit 2 are inserted into the soil layer to take samples. To facilitate the extraction of soil and rock samples from the drill pipe 1, a positioning plate 11 is fixedly connected inside the drill pipe 1 of this invention. A miniature electric push rod 12 is fixedly connected to the upper side of the positioning plate 11. The lower end of the miniature electric push rod 12 passes through the positioning plate 11 and is rotatably connected to a transmission rod 13. A scraper 14 is rotatably connected to the end of the transmission rod 13 away from the miniature electric push rod 12. A slide rail 15 is slidably connected to the upper end of the scraper 14. The slide rail 15 is fixedly connected to the positioning plate 11. The lower end of the miniature electric push rod 12 can move up and down and drive the scraper 14 to slide along the slide rail 15 through the transmission rod 13. A first groove 16 is provided on the side of the drill pipe 1 corresponding to the scraper 14 for it to pass through. Scraping grooves 141 are provided on both sides of the scraper 14. A soil discharge hole 142 is provided at the bottom of the scraper 14. A soil collection groove 17 is provided below the scraper 14. A second groove 18 is provided on the side of the drill pipe 1 for the soil collection groove 17 to pass through.

[0019] Specifically, the method of using this utility model is as follows: During the drilling process, the scraper 14 and the soil collection groove 17 are housed in the drill pipe 1. After reaching the designated position, the drill pipe 1 and the drill bit 2 no longer descend. The miniature electric push rod 12 pushes the scraper 14 out of the first groove 16. At this time, the drill pipe 1 is rotated again, and the soil enters the scraper 14 from the scraper groove 141 and then enters the soil collection groove 17 through the soil discharge hole 142. The soil collection groove 17 can be pulled out from the second groove 18.

[0020] Furthermore, the slide rail 15 has an inverted T-shaped cross-section.

[0021] Furthermore, the drill pipe 1 is provided with several scrapers 19 on its side for loosening the soil and rock. When the drill pipe 1 is rotated, the soil and rock are loosened, making it easier for the soil and rock to enter the scraper 14 from the scraper groove 141.

[0022] Furthermore, a protrusion 181 is connected to one side of the soil collection trough 17, and the protrusion 181 is fixedly connected to the side of the drill pipe 1 by bolt connection.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
