[0027] An example of the sample collection device provided by the present invention can be applied to the collection of soil samples in a nuclear contaminated environment, and can also be used in other sample collection fields, which can be specifically selected according to the actual situation. The sample collection device includes: a support base, a hollow cylinder 2, a rotating outer claw 1 and a power unit. The hollow cylinder 2 is fixed on the support base. The rotating outer claw 1 is sleeved on the hollow cylinder 2. An inlet 19 is provided at the root of the rotating outer claw 1. A feeding port 20 communicating with the inlet 19 is provided on the hollow cylinder 2. The hollow cylinder 2 is a container for holding the sample 21. Among them, the inlet 19 and the feeding port 20 are preferably long strip-shaped slot holes, and the opening of the feeding port 20 is always upward. During operation, the power unit drives the rotating outer claw 1 to rotate. The sample 21 is brought to the inlet 19 by the selected grasping outer claw. When the inlet 19 and the feeding port 20 communicate with each other, the sample 21 falls into the hollow cylinder 2 under the action of gravity. After the hollow cylinder 2 is filled with the sample, the rotating outer claw 1 is rotated to stagger the inlet 19 and the feeding port 20, so as to achieve the purpose of encapsulation. By arranging the hollow cylinder 2 inside the rotating outer claw 1, not only the integration degree of the device is improved, the space occupation is reduced, but also the structure is simple and convenient for use and maintenance. In addition, continuous sampling can be realized by this device, and the working efficiency is relatively high.

[0028] Specifically, the rotating outer claw 1 includes a cylinder and claw pieces uniformly arranged outside the cylinder. The number of the claw pieces can be selected according to the actual situation. The inlet 19 is arranged on the side wall of the cylinder close to the claw pieces. Among them, the claw pieces are preferably bent claw pieces with a preset radian, which is convenient for the transportation of the sample 21. In addition, in order to facilitate sampling, a serrated part is provided at the end of the rotating outer claw 1.

[0029] In order to facilitate the disassembly and assembly of the hollow cylinder 2, an installation flange is provided at one end of the hollow cylinder 2. The hollow cylinder 2 is fixed on the support base through the installation flange. During installation, the hollow cylinder 2 is directly pushed into the rotating outer claw 1. Under the action of the installation flange, its axial positioning can be realized, and finally it can be fixed on the support base through bolts. In addition, the detachable connection between the hollow cylinder 2 and the support base can also be realized by means of clamping.

[0030] Specifically, the power unit includes a rotating motor 11, a transmission belt 13 and belt pulleys. The rotating motor 11 is installed on the support base. The driving belt pulley 12 is installed on the output shaft of the rotating motor 11. The driven belt pulley 14 is installed and connected to one end of the rotating outer claw 1. This end of the rotating outer claw 1 can be connected to the driven belt pulley 14 through a transmission shaft 17. The transmission shaft 17 is installed on the support base through a B bronze bushing 18. The other end of the rotating outer claw 1 is installed on the support base through a connecting ring 15 and an A bronze bushing 16. Therefore, the rotation of the rotating outer claw 1 can be driven by the transmission belt 13. It should be noted that the transmission belt 13 is only a transmission mechanism, and a gear transmission mechanism can also be selected, as long as the power can be transmitted to the rotating outer claw 1. It can be specifically selected according to the actual situation, and this embodiment does not make specific limitations on this.

[0031] Further, it further includes a bearing part and an angle adjustment part. The support base is hinged to the bearing part through a horizontal hinge shaft, and the angle adjustment part is installed on the bearing part. When the bearing part is a moving vehicle, the bearing part is regarded as a part of the moving vehicle or is fully constrained and fixed to the moving vehicle, as shown in the appendix Figure 1 such as the A fixing plate 7 for fixing the angle adjustment part and the B fixing plate 8 for installing the support base in the appendix. When in the working state, the angle adjustment part can drive the support base to rotate downward by a certain angle so that the rotating outer claw 1 contacts the ground 22 to obtain the sample 21. When in the non-working state after sampling is completed, the support base can be driven to be in a horizontal state. Among them, the sample collection device can sample during the moving process or in the fixed state, and the sampling efficiency is higher in the moving state.

[0032] In addition, the support base specifically includes two support plates. The power part is installed on one of the B support plates 10. The adjustment end of the angle adjustment device is connected to the other A support plate 3. The rotating outer claw 1 is installed between one ends of the two support plates. The other ends of the support plates are installed on the B fixing plate 8 through a horizontal hinge shaft and a hinge support 9.

[0033] Specifically, the angle adjustment part includes a buffer part, a swing arm 5 and a driving part. The driving part is preferably a lifting motor 6. The two ends of the buffer part are respectively hinged to one end of the swing arm 5 and the support base. The other end of the swing arm 5 is connected to the output shaft of the driving part. When the lifting motor 6 drives the swing arm 5 to rotate, the swing arm 5 drives the support base to swing up and down through the buffer part. The buffer mechanism 4 can eliminate hard impacts for the device, thereby protecting the structural safety of the device. In addition, it can also adapt to different ground shapes and can change its height according to the ground shape. Therefore, it has strong environmental adaptability.

[0034] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0035] The above has introduced in detail a sample collection device provided by the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
