In the existing geological detection process, generally samples are taken at the detection site, and then the samples are crushed and screened before being detected and processed. However, during the crushing process of the samples, since there are many samples taken, different samples need to be crushed separately. But during the crushing process, due to the samples being crushed by extrusion, some samples will adhere to the crushing structure of the equipment, resulting in the mixing of different samples, thus affecting the detection results of the samples and reducing the accuracy of the detection results. In order to avoid the above problems, in the prior art, there is also a method of manually hammering a sample bag containing samples to crush the surface matrix samples. However, due to the inconvenient control of manual force, the hammering force is uneven, which is easy to damage the sample bag, and the crushing efficiency is low, and the manual labor intensity is high.

To facilitate the movement of the entire device, moving wheels may be provided at the bottom of the base 1, and wheel locks are provided on the moving wheels. After the base 1 is moved to the required position, the moving wheels are locked by the wheel locks to prevent the base 1 from moving during use. A driving motor 2 is fixedly provided at one end of the base 1. To facilitate the installation of the driving motor 2, the driving motor 2 is fixed to the base 1 by bolts, and a shock-absorbing rubber cushion layer 23 is provided between the driving motor 2 and the base 1.

The driving motor 2 is an adjustable-speed motor (a conventional technology in the field). The speed of the driving motor 2 is adjusted through the motor speed controller 27, thereby realizing the adjustment of the hammering frequency.

[0034] A hammer base 3 is fixedly provided at the other end of the base 1. The hammer base 3 can be fixed to the base 1 by bolts or welding. A hammering platform 4 is fixedly provided at the top of the hammer base 3, and a resin plate 19 is fixedly provided on the upper surface of the hammering platform 4; two relatively arranged rotating shaft seats 5 are fixedly provided in the middle of the base 1. The two rotating shaft seats 5 are arranged at intervals. A horizontally arranged rotating shaft 6 is provided between the two rotating shaft seats 5. Rotating shaft bearings 24 are fixedly provided on both of the two rotating shaft seats 5. Specifically, through holes for the rotating shaft 6 to pass through are provided on the rotating shaft seats 5.

[0035] In this embodiment, the output shaft of the driving motor 2 is in transmission connection with the rotating shaft 6 for driving the rotating shaft 6 to rotate axially. Specifically, one end of the rotating shaft 6 passes through and extends out of one of the rotating shaft seats 5 and is fixedly sleeved with a pulley 25. The pulley 25 is in transmission connection with the output shaft of the driving motor 2 through a connecting belt 26; a rotating wheel 7 is fixedly sleeved in the middle of the rotating shaft 6.

[0036] In this embodiment, a support frame 8 is fixedly provided on the base 1. The support frame 8 is arranged between the drive motor 2 and the rotating shaft seat 5. One end of a connecting arm 9 is hinged to the middle of the support frame 8. The top of the support frame 8 is connected to the middle of the connecting arm 9 through an elastic mechanism for applying a downward thrust to the connecting arm 9. Specifically, the elastic mechanism includes a first connecting rod 11, a second connecting rod 12, and a compression spring 13.

[0038] Embodiment Two

[0039] As Figure 3 shown, in this embodiment, a rotating bearing 17 is not sleeved on the rotating wheel 7. Instead, a roller 18 is rotatably provided at the bottom of the support seat 10. The roller 18 abuts against the outer peripheral wall of the rotating wheel 7. The roller 18 can reduce the friction between the support seat 10 and the rotating wheel 7 and improve the service life of the support seat 10 and the rotating wheel 7.

[0040] Working principle: Load the surface matrix sample to be crushed into a sample bag, place the sample bag on the upper surface of the resin plate 19, start the drive motor 2, the drive motor 2 rotates to drive the pulley 25 to rotate, thereby driving the rotating shaft 6 to axially rotate, and then driving the rotating wheel 7 to axially rotate with the axis of the rotating shaft 6 as the rotation axis. Since the axis of the rotating wheel 7 is spaced from the axis of the rotating shaft 6, a cam mechanism is formed by the rotating wheel 7. During the rotation of the rotating wheel 7, the connecting arm 9 is intermittently lifted so that the connecting arm 9 moves up and down with the connection point with the support frame 8 as the rotation point. At the same time, the compression spring 13 applies a downward force to the connecting arm 9, so that after the connecting arm 9 rotates to the highest point, under the action of its gravity and the thrust of the compression spring 13, it rotates downward so that the resin block 20 on the hammer head 22 hammers the sample bag containing the sample on the resin plate 19, thereby realizing effective crushing of the sample.

[0041] The utility model can improve the pretreatment efficiency of surface matrix samples, greatly shorten the sample treatment time, can adjust the hammering rate of the device according to the different hardness of the samples to process the samples to the sieving standard. The device has a simple structure, is convenient to operate, has uniform hammering force, is not easy to damage the sample bag, and effectively prevents sample contamination caused by sample bag breakage during the sample treatment process.
