The collection mechanism 2 can be used to automatically collect soil effectively and stably, avoiding the need for manual pressing to collect the soil. The soil adhered to the inside of the collection tube 211 can also be cleaned to prevent affecting the accuracy of the next sampling. This not only improves the practicality of the soil sampling device for an agronomist, but also increases the use effect of the soil sampling device for an agronomist.

[0023] Reference Figure 1 and Figure 2 A soil sampling device for an agronomist comprises a base plate 1, a collecting mechanism 2 is arranged above the base plate 1, the collecting mechanism 2 comprises an auxiliary frame 201, the bottom surface of the auxiliary frame 201 is fixedly connected to the upper surface of the base plate 1, two fixed blocks 202 are fixedly connected to the inner side wall of the auxiliary frame 201, the upper surface and the bottom surface of each fixed block 202 are fixedly connected to a reinforcing block 214, the side surfaces of the two groups of reinforcing blocks 214 away from each other are fixedly connected to the inner side wall of the auxiliary frame 201, the reinforcing block 214 can increase the fixed connection area between the fixed block 202 and the auxiliary frame 201, thereby improving the firmness of the connection between the two parties, avoiding the possibility of loosening of the fixed block 202 after long-term use, and increasing the durability of the device.

[0024] Reference Figure 2 A servo motor 203 is fixedly connected to the upper surface of the auxiliary frame 201, and a transmission rod 204 is fixedly connected to the output end of the servo motor 203 power. The bottom end of the transmission rod 204 passes through the auxiliary frame 201 and extends to the inside of the auxiliary frame 201. An auxiliary bearing 215 is sleeved on the outer surface of the transmission rod 204. The auxiliary bearing 215 is embedded in the inside of the auxiliary frame 201. The auxiliary bearing 215 can reduce the friction generated by the transmission rod 204 during rotation, making the transmission rod 204 more sensitive during rotation. At the same time, it can also reduce the wear speed of the transmission rod 204 and increase the service life of the transmission rod 204.

[0025] Reference Figure 2The outer surface of the transmission rod 204 is fixedly connected with a main gear 205, and two sub-gears 206 are arranged inside the auxiliary frame 201. The two sub-gears 206 are meshed with the main gear 205. The inner wall of each sub-gear 206 is fixedly connected with a threaded rod 207. The bottom end of each threaded rod 207 passes through the auxiliary frame 201 and the fixed block 202 in sequence and extends to the inside of the fixed block 202. The outer surface of each threaded rod 207 is sleeved with a rotating bearing 216. The two rotating bearings 216 are respectively embedded in the inside of the two fixed blocks 202. The rotating bearings 216 can reduce the friction generated by the threaded rod 207 during rotation, so that the threaded rod 207 is more sensitive when rotating, and can also reduce the wear rate of the threaded rod 207, effectively increasing the service life of the threaded rod 207.

[0026] Reference Figure 2 and Figure 3 The outer surfaces of the two threaded rods 207 are commonly threadedly connected with a moving block 208, and the moving block 208 is slidably connected to the inside of the auxiliary frame 201. A through hole 209 is opened on the upper surface of the bottom plate 1, and the upper surface of the moving block 208 is fixedly connected with a rotating motor 210. A protective shell 217 is arranged on the outside of the rotating motor 210, and the bottom surface of the protective shell 217 is fixedly connected to the upper surface of the moving block 208. The protective shell 217 can protect the rotating motor 210 and prevent external factors from interfering with the running rotating motor 210, and can also achieve dust-proof effect for the rotating motor 210.

[0027] Reference Figure 1 and Figure 3 The output end of the power of the rotating motor 210 passes through the moving block 208 and is fixedly connected to the collecting tube 211. The upper surface of the bottom plate 1 is fixedly connected to an auxiliary handle 218. The outer surface of the auxiliary handle 218 is fixedly connected to an anti-slip sleeve 219. The auxiliary handle 218 can provide a good force point for the device, increasing the convenience when the device needs to be pushed. The anti-slip sleeve 219 can increase the firmness when grasping the auxiliary handle 218.

[0028] Reference Figure 3 and Figure 4The inner wall of the collection tube 211 is slidably connected with a rubber block 212, and the outer surface of the rubber block 212 is fixedly connected with two push handles 213, and the two push handles 213 are slidably connected to the inside of the collection tube 211. The upper surface of the bottom plate 1 is fixedly connected with two support blocks 220, and the inner top wall of each support block 220 is fixedly connected with an electric telescopic rod 221, and the telescopic end of each electric telescopic rod 221 is fixedly connected with a connecting plate 222, and the bottom surface of each connecting plate 222 is fixedly connected with two universal wheels 223. The power generated by the electric telescopic rod 221 is used to drive the connecting plate 222 and the universal wheel 223 to rise or fall, which can improve the convenience when the device needs to be moved, and the universal wheel 223 can also be retracted into the auxiliary frame 201 during work.

[0029] Reference Figure 4 A stabilizing block 224 is fixedly connected to the back of each connecting plate 222, and each stabilizing block 224 is slidably connected to the inside of the auxiliary frame 201. The stabilizing block 224 can move simultaneously with the connecting plate 222, and use itself to improve the force position of the connecting plate 222 when moving, and can also limit the moving distance of the connecting plate 222.

[0030] Working principle: When in use, first connect the servo motor 203, the rotating motor 210 and the electric telescopic rod 221 to the power supply, and start the electric telescopic rod 221 so that the connecting plate 222 drives the universal wheel 223 to contact the ground, then push the auxiliary handle 218 to make the device move to the specified position through the cooperation of the universal wheel 223, and then rely on the electric telescopic rod 221 to retract the universal wheel 223 into the auxiliary frame 201, so that the bottom surface of the auxiliary frame 201 contacts the ground, effectively improving the stability during soil sampling. When soil sampling is required, start the servo motor 203 and the rotating motor 210, and use the power generated by the servo motor 203 to drive the transmission rod 204 and the main gear 205 to rotate forward or reverse, so that the two sub-gears 206 drive the threaded rod 207 Rotate, and then the moving block 208 drives the collecting tube 211 to move, so that the collecting tube 211 is inserted into the soil or removed from the soil. At the same time, the rotating motor 210 can drive the collecting tube 211 to rotate, further improving the effect of the collecting tube 211 when inserted into the soil, and avoiding the situation that the collecting tube 211 is stuck due to the hard soil. When it is necessary to clean the soil adhering to the inner wall of the collecting tube 211, press the push handle 213 to move the rubber block 212 inside the collecting tube 211. The rubber block 212 can scrape the soil on the inner wall of the collecting tube 211 during the movement, avoiding the soil adhering to the inner wall of the collecting tube 211 and affecting the accuracy of the next collection. Not only the practicality of the soil sampling device for agronomists is increased, but also the use effect of the soil sampling device for agronomists is improved.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
