Description

Technical Field

[0001] The utility model belongs to the field of soil detection, in particular to a soil sampler. Background Art

[0002] Most of the current soil samplers are long cylindrical and are driven by a rotating rod on the top to rotate into the soil to complete sampling.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0016] A soil sampler comprises a sampling tube 1, wherein a motor 2 is arranged above the top of the sampling tube 1, and the motor 2 is powered by a built-in battery. A "cross" block 3 is arranged at the bottom of the output shaft of the motor 2, a fixing block 4 is arranged at the top of the sampling tube 1, and a "cross" groove 5 is arranged at the top of the fixing block 4, and the "cross" block 3 can be plugged and matched with the "cross" groove 5, the top of the motor 2 is fixedly connected to the central position of the top of the cross bar 6, the upper part of the sampling tube 1 is fixedly connected to the inner ring of the bearing 7, a cross plate 8 is symmetrically arranged on both sides of the outer ring of the bearing 7, and the cross plate 8 can be located directly below the cross bar 6, a vertical fixing rod 9 is arranged at the bottom of both sides of the cross bar 6, the top of the fixing rod 9 is fixedly connected to the bottom of the cross bar 6, and a screw 10 is arranged at the fixed bottom, and a through hole 11 is opened at the corresponding position of the cross plate 8 and the screw 10, and the screw 10 can pass through the through hole 11, and the lower part of the screw 10 can be threadedly connected with a nut 12 to fix the screw 10 to the cross plate 8. When the utility model is used, the "cross" block 3 is plugged into the "cross" groove 5, and the corresponding side screw 10 passes through the through hole 11 and is fixed by the nut 12. Since the bottom of the fixing rod 9 cannot pass through the through hole 11, the fixing rod 9 and the cross bar 6 can be conveniently fixed, so that the "cross" block 3 and the "cross" groove 5 are tightly plugged into and matched, thereby ensuring that the motor 2 can stably drive the sampling tube 1 to rotate. At the same time, since the upper part of the sampling tube 1 is fixedly connected to the inner ring of the bearing 7, a cross plate 8 is symmetrically arranged on both sides of the outer ring of the bearing 7. Therefore, when the motor 2 drives the sampling tube 1 to rotate, the cross plate 8 will not be driven to rotate together. The sampling-related personnel only need to grasp the two ends of the cross bar 6 to conveniently complete the sampling operation.

[0017] Specifically, the fixed rod 9 described in this embodiment includes a vertically arranged sleeve 13 and a moving rod 14, the top of the sleeve 13 is fixedly connected to the bottom of the cross bar 6, the upper part of the moving rod 14 is located in the sleeve 13, the top of the sleeve 13 is connected to one end of the spring 15, the other end of the spring 15 is fixedly connected to the top of the moving rod 14, and the bottom of the moving rod 14 is provided with a screw 10. The spring 15 is arranged between the sleeve 13 and the moving rod 14 to play a buffering role when the bottom of the sampling tube 1 encounters a hard material such as a rock and causes vibration during the sampling process, thereby ensuring the long-term and stable use of the utility model.

[0018] Specifically, the bottom of the sampling tube 1 described in this embodiment has an inverted truncated cone-shaped thread head 16. The thread head 16 can reduce the resistance of drilling in the soil and reduce the difficulty of sampling.

[0019] Furthermore, soft grip covers 17 are respectively provided at both ends of the cross bar 6 described in this embodiment.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
