Through the grain pile down drilling mechanism 2, the grain store monitoring auxiliary device 100 realizes the upward movement and sinking in the grain pile, so as to sample the grain after reaching the target depth area, and releases the mobile carrying mechanism 4, thereby saving the energy consumption of the mobile carrying mechanism 4, increasing the endurance of the mobile carrying mechanism 4, and setting a sensor on the mobile carrying mechanism 4 to monitor the grain condition. In this way, the mobile carrying mechanism 4 can walk inside the grain pile after being released, and complete actions such as advancing and turning, so as to reach each area of the grain store, greatly expand the coverage area of the grain store grain condition monitoring, and effectively solve the problem of inconvenience of entering and leaving the store caused by the grain condition monitoring.

[0083] In the present embodiment, as shown in Figure 2 and Figure 3As shown, the telescopic down drill structure 21 comprises a shell 211 and a telescopic sleeve 212. The upper end of the shell 211 is connected with the carrier cabin 1. The shell 211 is formed with a mounting cavity 211a with an open upper end. The side wall of the mounting cavity 211a is provided with a plurality of first through holes. The telescopic sleeve 212 extends in the up-down direction. The telescopic sleeve 212 comprises an inner sleeve 2121 and an outer sleeve 2122 which are sleeved with each other.

Two support structures 22 are respectively arranged in the mounting cavity 211a and the outer sleeve 2122. Each support structure 22 is formed with a movable support part 22a. The two movable support parts 22a can respectively extend to the first through holes and the second through holes to assist the relative movement of the inner sleeve 2121 and the outer sleeve 2122.After the granary monitoring auxiliary device 100 enters the grain pile, firstly, the support structure 22 at the lower end works, thus the movable support part 22a of the support structure 22 at the lower end extends out of the outer sleeve 2122 to fix the lower end of the telescopic downhole structure 21, at this time, the first driving motor 2134 rotates forward to drive the first lead screw 2132 to rotate, so that the inner sleeve 2121 moves downward, and then the length of the whole granary monitoring auxiliary device 100 is shortened; then, the support structure 22 at the upper end works, thus the movable support part 22a of the support structure 22 at the upper end extends out of the inner sleeve 2121 to fix the upper end of the telescopic downhole structure 21, at this time, the movable support part 22a of the support structure 22 at the lower end is retracted into the outer sleeve 2122, and the support structure 22 at the lower end is retracted, thus the first driving motor 2134 reverses to drive the first lead screw 2132 to rotate, so that the outer sleeve 2122 moves downward, and then the length of the whole granary monitoring auxiliary device 100 is lengthened, and then the downhole of the granary monitoring auxiliary device 100 is realized. It should be noted that the granary monitoring auxiliary device 100 can also move upward, and the principle is the same as the downhole, which will not be described here.

[0084] Specifically, in the present embodiment, as Figures 4 to 7As shown, each of the support structures 22 comprises a mounting housing 221, a driving connecting plate 222, and two support plate sets 223.

The side wall of the first accommodating cavity is provided with a plurality of avoiding holes 2214. The partition plate 2213 is provided with two staggered sliding grooves 2213a. The driving connecting plate 222 is provided with two arc-shaped groove groups 2221. The two arc-shaped groove groups 2221 are arranged in one-to-one correspondence with the two sliding grooves 2213a. Each of the arc-shaped groove groups 2221 comprises two arc-shaped grooves 2221 arranged at intervals. The two support plate sets 223 are arranged in the first accommodating cavity in one-to-one correspondence with the two sliding grooves 2213a. Each of the support plate sets 223 comprises two support plates 2231 arranged at intervals and oppositely. Each of the support plates 2231 is provided with a sliding convex 2231a.

The output shaft of the torque motor 224 is arranged towards the first accommodating cavity and drives the driving connecting plate 222, so that the support plates 2231 can be extended out of the telescopic downhole structure 21 through the avoiding holes 2214 and retracted into the first accommodating cavity. The movable support part 22a comprises the two support plate sets 223. When the torque motor 224 rotates in the forward direction, the driving connecting plate 222 rotates to make the support plates 2231 slide outward along the sliding grooves 2213a, so that the support structure 22 is unfolded, thereby realizing the positioning and support of the telescopic downhole structure 21. When the torque motor 224 rotates in the reverse direction, the driving connecting plate 222 rotates to make the support plates 2231 slide inward along the sliding grooves 2213a, so that the support structure 22 is folded. The two support structures 22 work alternately to cooperate with the telescopic downhole structure 21, thereby realizing the downhole drilling and upward movement of the granary monitoring auxiliary device 100.

[0085] In the embodiment, as Figure 8The sampling mechanism 3 comprises a protective shell 31, a hopper 32, a sampling structure 33 and a sampling drive structure 34.

The sampling drive structure 34 comprises a sliding sleeve 341 and a sampling drive motor 342. The sliding sleeve 341 is provided with a mounting bracket 3411 fixed to the upper end of the rotating shaft 331. The sampling drive motor 342 is installed on the mounting bracket 3411. The sliding sleeve 341 is movably sleeved in the protective shell 31 above the sampling structure 33, so that the sampling structure 33 can be extended from the lower end of the protective shell 31. The output shaft end of the sampling drive motor 342 is provided with a second gear 3421 engaged with the first gear 3311, so as to rotate the sampling structure 33 for sampling. After the grain storehouse monitoring auxiliary device 100 drills to the specified depth, the sampling mechanism 3 performs grain sampling. First, the sliding sleeve 341 moves downward to extend the sampling structure 33 partially out of the protective shell 31. At this time, the sampling drive motor 342 rotates forward, the second gear 3421 engages with the first gear 3311 to rotate the sampling structure 33, so that the sampling groove 333 is filled with grain.
