Description

Technical Field

[0001] The utility model relates to the technical field of forage industry equipment, in particular to a soil sampler for an inter-row mixed sowing pasture land. Background Technique

[0002] At present, there is no particularly suitable tool for soil layer sampling in inter-row mixed sowing pasture land. Most of them still choose ordinary soil drills. Ordinary soil drills are no problem for same-row mixed sowing or single sowing pasture land, but there are many limitations in inter-row mixed sowing pasture land. For example, there are always human differences in the spacing between each drill, and it is impossible to sample evenly between rows, resulting in too large sample differences, thus affecting the data accuracy of sampling.

[0003] For example, the patent document with the application number 202320170882.0 discloses a soil sampler for an inter-row mixed sowing pasture land. The utility model discloses a soil sampler for an inter-row mixed sowing pasture land, including an operation cross bar. A sliding cylinder is slidably arranged on the operation cross bar. A fastening screw for positioning is arranged on the sliding cylinder. The sliding cylinder is fixedly connected with a connecting frame. The bottom end of the connecting frame is fixedly connected with a sampling column. A chute is opened on the operation cross bar. A sliding block is fixedly connected to the sliding cylinder. The sliding block is slidably connected with the chute. And scale lines are engraved on the outer wall of the operation cross bar. The sampling column includes a U-shaped frame fixedly connected with the connecting frame. The U-shaped frame is fixedly connected with a central plate. Semi-cylindrical shells are symmetrically hinged on the central plate. Scale lines are engraved on both semi-cylindrical shells. A limiting cylinder is slidably sleeved on the outer sides of the two semi-cylindrical shells. The limiting cylinder is slidably connected with the U-shaped frame. Through the combined use of the operation cross bar, the fastening screw and the scale lines arranged in the utility model, the distance between the sampling columns can be adjusted according to actual needs, so as to sample evenly between rows and improve the data accuracy of sampling. However, for this soil sampler for an inter-row mixed sowing pasture land, when soil sampling is required for different inter-row grasslands, it is extremely time-consuming and laborious to continuously adjust the distance between the two soil samplers using screws.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a soil sampler for an inter-row mixed sowing pasture land is proposed. Content of the Utility Model

And a first drive block is spirally installed on the surface of the first spiral drive rod. A rotation knob is arranged at the front end of the first spiral drive rod. And a limiting plate is arranged at the rear end of the first spiral drive rod. A scale rod is slidably installed on the rear surface of the support rod.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figure 1 - Figure 2 shown, a soil sampler for an intercropped and mixed-sown pasture land includes a support rod 1. A fixing block 101 is arranged at the rear end of the support rod 1, and a first spiral transmission rod 2 is installed through the surface of the fixing block 101. A first transmission block 102 is spirally installed on the surface of the first spiral transmission rod 2. The advantage of this setting is that through the setting of the first spiral transmission rod 2, the first transmission block 102 can be driven to move through the spiral transmission method, so that it can drive the fixing block 101 to adjust the spacing along the scale rod 203 more accurately. At the same time, it is not easy to loosen and speeds up the adjustment speed, improving the working efficiency of the user.

[0021] Furthermore, a rotating knob 201 is arranged at the front end of the first spiral transmission rod 2, and a limiting plate 202 is arranged at the rear end of the first spiral transmission rod 2. The advantage of this setting is that through the setting of the rotating knob 201, the rotation of the first spiral transmission rod 2 can be assisted, making the adjustment more convenient.

[0022] Furthermore, a scale rod 203 is slidably installed on the rear surface of the support rod 1. This setting is an existing device and will not be elaborated too much.

[0023] As Figure 3 - Figure 4 shown, a connecting plate 3 is arranged at the lower end of the support rod 1, and a left housing 304 is arranged at the lower end of the connecting plate 3. A connecting block 301 is arranged at the front end of the connecting plate 3, and a second spiral transmission rod 302 is spirally installed on the surface of the connecting block 301. A second transmission block 303 is spirally installed on the surface of the second spiral transmission rod 302, and a right housing 305 is arranged at the lower end of the second transmission block 303. The advantage of this setting is that through the setting of the second spiral transmission rod 302, the left housing 304 and the right housing 305 can be quickly separated to facilitate the extraction of samples.

[0024] Furthermore, the lower ends of the left housing 304 and the right housing 305 are tapered, and spiral material taking grooves 306 are arranged on the inner walls of the right housing 305 and the right housing 305. The advantage of this setting is that through the setting of the spiral material taking grooves 306, the soil samples can be better retained, avoiding the phenomenon of insufficient sampling due to soft soil.

[0025] Working principle: When using the soil sampler for the inter-row mixed sowing pasture land, first, rotate the rotary knob 201 to drive the first spiral drive rod 2 to rotate, and at the same time drive the first drive block 102 to move. After adjusting to the appropriate angle according to the scale rod 203, insert the soil sampler into the soil for sampling. After the sampling is completed, drive the second drive block 303 through the second spiral drive rod 302 to separate the left housing 304 and the right housing 305 to take out the sample. This is the working principle of the soil sampler for the inter-row mixed sowing pasture land.
