Description
Technical Field
[0001] The utility model relates to the technical field of earth-breaking samplers, in particular to an earth-breaking sampler for construction engineering quality inspection. Background Art
[0002] Construction projects refer to engineering entities formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's production, living, learning, and public activities. In order to ensure the safety of construction projects that have been built, are under construction, and will be built, it is necessary to survey the building foundation to determine whether the foundation meets the standards. When surveying the foundation, it is necessary to break the ground for the foundation, and then collect and test the soil of the foundation.
[0003] However, most of the existing soil-breaking equipment can only break the soil, and cannot complete soil sampling well. When sampling, the soil is mostly sampled through a sampling barrel. When the sampling barrel is moving, the sample is easy to fall out of the barrel, especially when encountering relatively dry and fine soil, the soil can hardly be taken out completely from the place where the soil is broken. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a soil breaking sampler for construction engineering quality inspection, which solves the problems mentioned in the above background.
[0005] The utility model provides the following technical solutions:

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1-5, including a soil-breaking spiral rod 1, a through hole is provided in the middle of the soil-breaking spiral rod 1, and a spiral blade is fixed on the outer surface to facilitate soil breaking; an inner cylinder 2 is sleeved inside the soil-breaking spiral rod 1, and a convex ring is fixed on the inner wall of the soil-breaking spiral rod 1, and the bottom end of the inner cylinder 2 is restricted by the convex ring; a sampling cylinder 3 is sleeved inside the inner cylinder 2, and the diameter of the sampling cylinder 3 is smaller than the diameter of the through hole at the bottom of the soil-breaking spiral rod 1, so that the sampling cylinder 3 can extend from the bottom of the soil-breaking spiral rod 1 after the soil-breaking spiral rod 1 breaks the soil, and the soil is sampled through the sampling cylinder 3, and after sampling, the sampling cylinder 3 is directly drawn out from the inside of the inner cylinder 2 through the top of the soil-breaking spiral rod 1, so as to facilitate the collection of samples; a baffle 4 is installed at the bottom of the inner cylinder 2 The inner wall of the inner cylinder 2 and the baffle 4 are symmetrically arranged. The two baffles 4 can rotate through the rotating shaft. A convex ring is fixed on the inner wall of the inner cylinder 2 at the top of the baffle 4, and the convex ring prevents the baffle 4 from rotating upward; a torsion spring 5 is installed at the bottom of the baffle 4, and one end of the torsion spring 5 is fixed to the inner wall of the soil-breaking spiral rod 1, and the other end is fixed to the bottom surface of the baffle 4. The baffle 4 is turned upward without external pressure through the elastic force of the torsion spring 5, and due to the limitation of the convex ring of the inner cylinder 2, the baffle 4 is perpendicular to the inner cylinder 2 after turning over. When the two sets of baffles 4 are perpendicular to the inner cylinder 2, the bottom of the inner wall of the inner cylinder 2 is closed. When the sampling cylinder 3 is sampling, pressure is applied to the baffle 4 through the sampling cylinder 3, so that the baffle 4 and the torsion spring 5 are turned upward. The sampling tube 3 normally moves toward the bottom of the soil-breaking spiral rod 1. After the sampling tube 3 takes a sample, it is moved upward. After the sampling tube 3 moves upward, the baffle 1 4 is automatically reset by the torsion spring 1 5, and the bottom of the inner tube 2 is reclosed to prevent the soil sampled by the sampling tube 3 from falling. The baffle 2 6 is installed on the inner wall of the soil-breaking spiral rod 1 near the bottom end, and the sampling tube 3 is divided into three groups of equidistant combinations. The torsion spring 2 7 is installed below the baffle 2 6, and one side of the torsion spring 2 7 is fixed to the inner wall of the soil-breaking spiral rod 1, and the other end is fixed to the bottom of the baffle 2 6. The three groups of sampling tubes 3 are brought close to each other by the thrust of the torsion spring 2 7 to seal the bottom of the soil-breaking spiral rod 1 to prevent the soil-breaking spiral rod 1 from falling when it is over-breaking the soil. The soil enters the soil-breaking spiral rod 1 from the bottom of the soil-breaking spiral rod 1. When the sampling tube 3 takes samples, the baffle 26 is pushed downward by the sampling tube 3 to rotate. After the baffle 26 rotates, the sampling tube 3 can move downward normally, and while the sampling tube 3 pushes the baffle 26, the soil accumulated between the baffle 26 and the soil-breaking spiral rod 1 is cleaned, so that the soil sampled by the sampling tube 3 is the sample at the specified position, thereby improving the accuracy of the sample data. When the sampling tube 3 is away from the baffle 26, the torsion spring 27 pushes the baffle 26 upward. After the baffle 26 flips upward, one end of the bottom of the baffle 26 contacts each other to form a cone, and when the soil-breaking spiral rod 1 descends to break the soil, the baffle 26 can remain in position when the soil pushes the baffle 26 upward.
[0029] A fixed box 8 is fixed to the outside of the ground-breaking screw rod 1, and a movable hole is provided at the bottom of the fixed box 8 corresponding to the position of the ground-breaking screw rod 1. A roller is installed at the bottom of the fixed box 8 for easy movement, and the ground-breaking screw rod 1 can be conveniently positioned through the fixed box 8 to reduce the movement and tilting of the ground-breaking screw rod 1 when breaking the ground. A screw rod 9 is installed inside the fixed box 8, and the screw rod 9 is located on one side of the ground-breaking screw rod 1. A motor 10 is fixed on the top of the screw rod 9. The surface of the motor 10 is connected to the lifting plate 11 through a nut seat. A guide rod 12 is installed at the end of the lifting plate 11 away from the screw rod 9. A movable hole is provided on the surface of the lifting plate 11 corresponding to the position of the ground-breaking screw rod 1, and a convex ring is fixed on the surface of the ground-breaking screw rod 1 below the lifting plate 11. When the motor 10 drives the lifting plate 11 to move up and down through the screw rod 9, the lifting plate 11 can drive the ground-breaking screw rod 1 to move up and down.
[0030] A protective plate 13 is fixed to the top of the lifting plate 11. A transmission gear 14 is fixed to the outer surface of the earth-breaking screw rod 1 between the lifting plate 11 and the protective plate 13. A transmission gear 2 15 is installed on the bottom of the protective plate 13, which is located on the side of the earth-breaking screw rod 1. The gear teeth of the transmission gear 2 15 are meshed with the gear teeth of the transmission gear 1 14. The top of the transmission gear 2 15 is connected to a motor 2 16, which is installed on the top of the protective plate 13. The motor 2 16 drives the transmission gear 2 15 to rotate, so that the transmission gear 2 15 drives the transmission gear 1 14 to rotate. When the transmission gear 1 14 rotates, it drives the earth-breaking screw rod 1 to rotate, and cooperates with the motor 10 to drive the earth-breaking screw rod 1 to move downward through the lifting plate 11, so that the earth-breaking screw rod 1 performs earth-breaking work.
[0031] Working principle: when breaking the ground for sampling, the fixed box 8 is moved to the position where the ground needs to be broken, and the motor 10 drives the screw rod 9 to rotate, and the screw rod 9 drives the lifting plate 11 to move downward. While the lifting plate 11 moves downward, the motor 2 16 drives the transmission gear 2 15 to rotate, and the transmission gear 2 15 drives the transmission gear 1 14 to rotate the ground-breaking spiral rod 1, so that the spiral blade on the surface of the ground-breaking spiral rod 1 breaks the ground. After the ground-breaking spiral rod 1 moves to the specified position, the staff presses the sampling tube 3 downward, and the sampling tube 3 presses the baffle plate 4 The baffle 14 and the baffle 26 apply pressure to make the baffle 14 and the baffle 26 rotate downward. After the baffle 14 and the baffle 26 are opened, the bottom of the sampling tube 3 falls to the sampling position. The soil enters the sampling tube 3 by pressing and rotating the sampling tube 3, and then the sampling tube 3 is moved upward. After the sampling tube 3 moves to the inner tube 2, the baffle 14 is closed again by the thrust of the torsion spring 15, and the bottom of the sampling tube 3 is blocked by the baffle 14, so that the sample collected in the sampling tube 3 falls, and the inner tube 2 and the sampling tube 3 are pulled out from the soil-breaking spiral rod 1, so that the samples can be collected separately.
[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
