[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] An equal amount sampling mechanism for a geotechnical ring cutter: comprising a positioning seat 1, a conical anchor rod 2 is fixedly connected to the bottom of the positioning seat 1, a limiting ring 3 is fixedly connected to the surface of the conical anchor rod 2, the limiting ring 3 can limit the position of the positioning seat 1 and the limiting ring 3 on the soil, a sleeve 5 is slidably connected to the surface of the limiting ring 3, a geotechnical ring cutter body 4 is snap-connected to the bottom of the sleeve 5, a connecting rod 6 is fixedly connected to the upper surface of the sleeve 5, a hammer block 7 is fixedly connected to the surface of the connecting rod 6, a fixed disk 8 is fixedly connected to the surface of the connecting rod 6, and the surface of the fixed disk 8 The upper through hole is connected with a bolt 9, and the bottom of the bolt 9 is fixedly connected with a limit rod 10, and the bottom of the limit rod 10 is fixedly connected with a conical head 11, and a nut 12 is threadedly connected on the surface of the bolt 9. The sampling mechanism can insert the limit rod 10 into the soil around the earth ring cutter body 4 during the sampling process. The limit rod 10 can detect whether there are rocks for the earth ring cutter body 4, thereby avoiding damage to the earth ring cutter body 4. The limit rod 10 can also be replaced after being seriously damaged, which greatly reduces the damage rate of the earth ring cutter body 4 and reduces the sampling cost.

[0024] Furthermore, a slot is provided at the bottom of the sleeve 5, and the top of the earth-working ring cutter body 4 is snap-connected to the slot at the bottom of the sleeve 5. The sleeve 5 positions the earth-working ring cutter body 4 on the limiting ring 3. When the sleeve 5 slides downward on the limiting ring 3, the earth-working ring cutter body 4 will be driven into the soil.

[0025] Furthermore, the inner ring diameter of the limit ring 3 is equal to the outer ring diameter of the sleeve 5, the inner ring diameter of the limit ring 3 is larger than the outer ring diameter of the earth ring cutter body 4, the slot of the sleeve 5 is circular, and the slot diameter of the sleeve 5 is equal to the outer ring diameter of the earth ring cutter body 4, which makes it convenient for the sleeve 5 to drive the earth ring cutter body 4 into the soil.

[0026] Furthermore, the connecting rod 6 and the hammer block 7 slide on the inner surface of the limit ring 3 through the sleeve 5, and hammer on the upper surface of the earth ring cutter body 4, which can make the horizontal height of the hammer block 7 drop. The hammer block 7 drives the connecting rod 6 and the sleeve 5 to descend on the limit ring 3, and the earth ring cutter body 4 penetrates the inner surface of the limit ring 3 through the sleeve 5, so that the earth ring cutter body 4 enters the soil.

[0027] Furthermore, a circular hole is opened on the surface of the fixing plate 8, the bolt 9 is connected to the circular hole of the fixing plate 8 through a hole, the limiting rod 10 and the conical head 11 pass through the circular hole of the limiting ring 3, a circular hole is opened on the surface of the positioning seat 1, the limiting rod 10 is connected to the circular hole of the positioning seat 1 through a hole, the conical head 11 passes through the circular hole of the positioning seat 1, and the limiting rod 10 can be better inserted into the soil through the conical head 11.

[0028] Furthermore, the length of the limit rod 10 is longer than the length of the earth ring cutter body 4, and the horizontal height of the fixed plate 8 is higher than the horizontal height of the sleeve 5. The higher horizontal height of the fixed plate 8 ensures that the sleeve 5 can completely drive the earth ring cutter body 4 into the soil before the fixed plate 8 contacts the upper surface of the limit ring 3, thereby ensuring that the limit rod 10 can always be driven deeper than the earth ring cutter body 4.

[0029] Furthermore, the nut 12 fixes the bolt 9 on the surface of the fixed plate 8, and the limit rod 10 and the conical head 11 are fixedly installed on the bottom of the fixed plate 8 through the bolt 9. The limit rod 10 and the conical head 11 are provided in multiple groups and are linearly and evenly arranged on the surface of the fixed plate 8. During the descending process of the connecting rod 6 and the sleeve 5, the fixed plate 8 drives the limit rod 10 and the conical head 11 to descend synchronously, so that the horizontal height of the conical head 11 in the soil is always at the bottom of the first earth ring cutter body 4, ensuring that the limit rod 10 and the conical head 11 can detect the rocks inside the soil.

[0030] Working principle: the bottom of the earthwork ring cutter body 4 is snap-connected to the sleeve 5, and then the earthwork ring cutter body 4 is passed through the inner ring of the limit ring 3 and inserted into the soil, and the hammer block 7 is hammered by a hammer. The hammer block 7 applies pressure to the earthwork ring cutter body 4 through the connecting rod 6 and the sleeve 5, so that the earthwork ring cutter body 4 is inserted into the soil. At this time, the fixed plate 8 follows the connecting rod 6 and descends synchronously, and the fixed plate 8 drives the limit rod 10 to descend. The limit rod 10 is inserted into the soil through the conical head 11. The horizontal height of the conical head 11 is lower than the bottom of the earthwork ring cutter body 4, so that the limit rod 10 can detect whether there are rocks in the soil around the earthwork ring cutter body 4 in advance through the conical head 11. When the hammering is blocked, the earthwork ring cutter body 4 is pulled out in time to avoid damage to the earthwork ring cutter body 4.

[0031] When the conical head 11 is damaged, the nut 12 is rotated on the bolt 9 to make the nut 12 detach from the bolt 9, and the limiting rod 10 and the conical head 11 are pulled out from the circular hole of the limiting ring 3 through the bolt 9, so that the limiting rod 10, the conical head 11 and the bolt 9 are removed from the fixing plate 8, and can be installed on the fixing plate 8 again through the nut 12, so that the conical head 11 is easy to replace.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
