Technical Field

[0001] The utility model relates to the technical field of soil sample collection, in particular to a soil sample collection device for farmland soil treatment and restoration. Background Art

[0002] A soil auger is a common manual collection device. It is also a frequently used and popular manual sampling device in farmland soil sampling. A soil auger usually consists of a drill rod with a T-shaped handle and a drill bit with a soil sampling hole. When in use, the drill rod is moved until the drill bit is inserted into the soil for sampling. After the sampling is completed, the drill rod is pulled out until the drill bit is removed from the soil to obtain a soil sample.

[0003] In the existing soil sampling device, during the soil sampling process, the rotating drill bit is prone to tilt when entering the soil, which is not conducive to the operator's holding operation and affects the normal soil sampling. For this reason, we propose a soil sampling device for farmland soil management and restoration. Utility Model Content

A collection rod 8 is arranged inside the sleeve 1, and a rotating handle 5 is installed on the top of the sleeve 1. The sleeve 1 is provided with two symmetrical collection holes 7, and spiral blades 6 are arranged outside the collection holes 7. The bottom end of the sleeve 1 is a conical structure, and the side wall of the bottom end of the sleeve 1 is installed with spiral blades 6. The spiral blades 6 can assist the sleeve 1 to drill into the soil when the sleeve 1 rotates. When collecting soil samples from farmland soil, the four support rods 3 can be unfolded, and the support rods 3 and the support feet 4 can be relied on to perform a stable operation of the collection device, so that when the operator rotates the sleeve 1 and collects soil through the collection holes 7, the device body will not shake, which is convenient for the operator to use and improves the collection efficiency.

[0032] See also Figure 3 and Figure 5 The sleeve 1 and the collecting rod 8 form a rotating structure, a handle is provided at the top of the collecting rod 8, and a screw collecting groove 10 is provided at the bottom of the collecting rod 8, and the collecting hole 7 provided at the bottom of the sleeve 1 corresponds to the position of the collecting groove 10 provided by the collecting rod 8, and the collecting groove 10 can cover the collecting hole 7 provided at the bottom of the sleeve 1 by rotating the collecting rod 8.

[0034] Working principle: When collecting soil samples from farmland soil, first rotate and unfold the four support rods 3, and through the support feet 4 rotatably connected to the support rods 3, the device can be stably placed on the soil, and the convex blocks 11 are set at the bottom of the support feet 4. The convex blocks 11 can increase the friction between the support feet 4 and the soil, thereby avoiding the shaking of the device when collecting soil samples. Then the operator holds the handle 5 to drive the entire sleeve 1 to rotate. Under the rotation of the spiral blade 6, the sleeve 1 drills into the soil, and then rotates the collection rod 8 to make the collection slot 10 coincide with the collection hole 7, so that the soil collection sample passes through the collection hole 7 and enters the collection slot 10 to complete the operation of collecting soil samples. During the collection process, the device body will not shake, which is convenient for operators to use and improves the collection efficiency;

[0035] Secondly, after the collection is completed, the collection rod 8 is rotated to reset, so that the collection hole 7 can be blocked, so that in the process of the sleeve 1 rotating and rising, no other soil will enter the collection groove 10, so that the device can accurately collect soil samples at a specified depth, thereby improving the accuracy of the collection;

[0036] Finally, by setting the slide groove 12, a limiting operation can be performed on the rotation angle of the collection rod 8, so as to ensure that when the collection rod 8 rotates, the collection groove 10 can be accurately overlapped with the collection hole 7, so as to ensure that the soil sample can enter the collection groove 10.
