[0028] Referring to "embodiment" herein means that the specific features, structures or characteristics described in connection with the embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0029] An embodiment of the present utility model provides a snow density testing device, as Figures 1-6 shown. The snow density testing device is assembled on a snowmobile and includes:

[0030] A connecting frame 100, the connecting frame 100 includes an upper frame 110, a connecting rod 120, a chassis 130 and a top beam 140. The upper frame 110 and the chassis 130 are connected by the connecting rod 120 as the main equipment carrier, and the top beam 140 is arranged on the upper frame 110. The top beam 140 is connected to the chassis of the snowmobile by bolts;

[0031] An induction unit 200, the induction unit 200 includes an upper crossbeam 210, a lower crossbeam 220 and a pressure induction module arranged between the upper crossbeam 210 and the lower crossbeam 220. During the driving of the snowmobile, the pressure induction module is in direct contact with the snow road surface;

[0032] The snowmobile in this application specifically refers to a snowmobile using a rear three-point single-track drive method. The connecting frame 100 is arranged between two sets of front fork arms, and the space between the two sets of front fork arms is used as the installation area of the induction unit 200; with the help of the top beam 140, the connecting frame 100 is fixed on the chassis of the snowmobile;

[0033] During the snow compaction measurement process, through the slow driving of the snowmobile, the connecting frame 100 presses the pressure sensing module 230 against the ground. When encountering soft ground, the pressure on the pressure sensing module 230 from the ground decreases, and the pressure measured by the pressure sensing module 230 also decreases, indicating that there is an area with low snow density in this area; the pressure sensing module 230 here is a pressure testing device. In addition to the testing components used in this application, other compaction testing technical routes can also be adopted to mount corresponding sensing modules as data testing equipment; this application mainly simplifies the structural complexity of the snow compaction acquisition device with the help of the snowmobile, reduces the overall complexity of the testing device by the flexible assembly of the connecting frame 100 and the sensing unit 200, and further reduces the cost of the testing device by relying on the all-terrain cross-country ability of the snowmobile to meet the mobility needs.

[0034] As a preferred implementation manner in this embodiment, both the upper frame 110 and the chassis 130 are square frames. The outer dimension of the upper frame 110 is smaller than that of the chassis 130. The connecting rod 120 is connected to the corners of the upper frame 110 and the chassis 130; there is a groove on the chassis 130, and the upper cross beam 210 is assembled in the groove.

[0035] In this embodiment, the upper frame 110, the connecting rod 120 and the chassis 130 form a frustum structure, which has higher stability and can better resist the impact during movement, avoiding abnormal states such as the frame falling apart caused by vibration; the number of the top beams 140 is two groups and they are arranged in parallel on the upper frame 110. The top beams 140 are arranged parallel to the advancing direction of the snowmobile, and the arrangement direction of the upper cross beam 210 is parallel to the arrangement direction of the top beams 140; the regulation of the top beams 140 will be adapted according to the snowmobile to ensure that the connection of the connecting frame 100 can keep the sensing unit 200 in contact with the snow ground.

[0036] As a preferred implementation manner in this embodiment, the pressure sensing module 230 includes a shaft rod 231, a spring 234 and a pressing block 233 provided at the front end of the shaft rod 231; there is a shaft hole on the lower cross beam 220 for the shaft rod 231 to pass through. There is also a pressing ring 232 on the outer side of the shaft rod 231. The diameter of the pressing ring 232 is larger than the aperture of the shaft hole. A part of the structure of the shaft rod 231 passes through the lower cross beam 220. The pressing block 233 is arranged at the end of the shaft rod 231 passing through the lower cross beam 220. The spring 234 is nested at one end of the shaft rod 231 away from the pressing block 233. There is an annular sleeve on the upper cross beam 210. One end of the spring 234 abuts against the inside of the sleeve, and the other end abuts against the pressing ring 232; in this application, the pressing block 233 is in a boat-shaped structure, and the arc surface of the pressing block 233 is in contact with the snow to maintain a long-term compressed state. When the pressure decreases, the spring 234 will push the shaft rod 231 away from the sleeve to ensure that the pressing block 233 is in a pressed state with the ground.

[0037] During the driving process of the snowmobile, the pressing block 233 is in a state of continuous force application. When encountering a soft area, the ground support force cannot support the spring 234. At this time, the shaft rod 231 will move away from the annular sleeve under the action of the spring 234. In this application, the pressure induction during the traveling process is mainly used as a test means. A pressure sensor 235 is provided in the annular sleeve as a data acquisition device. When the pressure received by the pressure sensor 235 decreases, it indicates that there is a soft area in this area and the snow density is low. The pressure sensor 235 is placed in the sleeve, and one end of the spring 234 away from the pressure ring 232 abuts against the pressure sensor 235.

[0038] It should be noted that for the foregoing embodiments, for the sake of simple description, they are all expressed as a series of action combinations. However, those skilled in the art should know that the present invention is not limited by the described action sequence, because according to the present invention, certain steps may be carried out in other sequences or simultaneously.
