[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0020] Please see Figures 1-4 This utility model provides a technical solution for a soil sampling device for forestry and grassland surveying: including a support frame 1, a cone structure 2, a fixing frame 201, a rod 202, a limiting frame 203, a first electric telescopic rod 3, a limiting block 4, a rotating shaft 5, a fixing block 6, a limiting iron block 7, a weeding cylinder 8, a bidirectional motor 9, a cutting blade 10, a return spring 11, a limiting rod 12, a sampling cylinder 13, a sampling spiral rod 14, a limiting magnet 15, a sampling cover plate 16, a slider 17, a second electric telescopic rod 18, and a limiting groove 19.
[0021] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 and Figure 3 As shown, the support frame 1 has a tripod structure, and two limiting blocks 4 are provided on the upper front side of the support frame 1. The limiting blocks 4 are arranged perpendicularly to each other. The front end of the rotating shaft 5 has a "T" shape, and the rotation range of the rotating shaft 5 on the support frame 1 via the limiting blocks 4 is 0-90°. The fixing block 6 fixedly connected to the rotating shaft 5 has an "L" shape. The lower end of the support frame 1 is fitted with a cone structure 2, which includes a fixing frame 201, a rod 202, and a limiting frame 203. The lower end of the fixing frame 201 is fixedly connected to the rod 202, and limiting frames 2 are provided on both side walls of the fixing frame 201. 03. A support frame 1 is connected through the inside of the limiting frame 203. The output end of the first electric telescopic rod 3 is fixedly connected to the lower middle part of the fixed frame 201. The insertion rod 202 forms a sliding structure at the lower end of the support frame 1 through the limiting frame 203, and the lower end of the insertion rod 202 is a pointed cone structure. When the support frame 1 is placed on the grass to be sampled, the power switch of the first electric telescopic rod 3 is turned on. When the first electric telescopic rod 3 retracts, it pulls the fixed frame 201 downward. The fixed frame 201 slides on the support frame 1 through the limiting frame 203, which makes it easy to insert the insertion rod 202 into the soil, thus making it easy to install and fix the support frame 1 and convenient to use. Combination Figure 1 and Figure 2As shown, a bidirectional motor 9 is fixedly installed inside the lower end of the weeding cylinder 8, and a cutting blade 10 is fixedly installed at the output end of the bidirectional motor 9. A limiting rod 12 is connected through the upper end of the weeding cylinder 8, and a return spring 11 is sleeved on the outer surface of the limiting rod 12. The lower end of the limiting rod 12 is fixedly connected to the lower end of the fixing block 6. The weeding cylinder 8 slides on the lower end of the fixing block 6 via the limiting rod 12, thus facilitating the adjustment of the height position of the weeding cylinder 8. When the power switch of the bidirectional motor 9 is turned on, the bidirectional motor 9 drives the cutting blade 10 to rotate, facilitating the cutting of grass from top to bottom for rapid weed removal. The outer surface of the sampling cylinder 13 is bolted with a sampling cover plate 16, and a bidirectional motor 9 is installed inside the upper end of the sampling cylinder 13. The output end of the bidirectional motor 9 is fixedly installed with a sampling screw rod 14. Similarly, the sampling cylinder 13 slides at the lower end of the fixing block 6 through the limiting rod 12, so that the sampling screw rod 14 can rotate under the action of the bidirectional motor 9, which facilitates drilling the soil and then facilitating the rotation and transfer of soil into the sampling cylinder 13 for collection. Then, the output end of the bidirectional motor 9 is rotated in the opposite direction to facilitate the removal of the sampling cylinder 13 and the opening of the sampling cover plate 16 to facilitate the removal of soil samples and cleaning. Combination Figure 1 , Figure 2 and Figure 4 As shown, the width of the limiting magnet 15 is greater than the width of the limiting block 7, and the total thickness of the limiting magnet 15 and the limiting block 7 is not greater than the internal height of the limiting groove 19. The lower end face of the limiting groove 19 has an arc-shaped structure, and the width of the upper opening of the limiting groove 19 is greater than the width of the limiting block 7, while the width of the upper opening of the limiting groove 19 is less than the width of the limiting magnet 15. When the fixing block 6 rotates 90° on the support frame 1 via the rotating shaft 5, the limiting block 7 on the fixing block 6 and... The limiting magnet 15 on the weeding cylinder 8 or the limiting iron block 7 on the fixing block 6 engages with the limiting magnet 15 on the sampling cylinder 13 at the limiting groove 19. The upper opening width of the limiting groove 19 is smaller than the width of the limiting magnet 15. Thus, when the second electric telescopic rod 18 retracts and pulls the slider 17 downward, the limiting magnet 15 and the limiting iron block 7 separate, making it easier for the weeding cylinder 8 or the sampling cylinder 13 to slide downward on the fixing block 6, facilitating the sampling work. This is the working process of the soil sampling device for forestry and grassland survey.
[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
