Technical Field
[0001] The utility model belongs to the technical field of soil sampling tools, and more specifically, it relates to a soil pushing tooling for an undisturbed soil drill and a soil sampling device. Background Technique
[0002] A soil pushing block is slidably arranged in a soil sampling bit of an undisturbed soil drill, and the soil pushing block is connected with a soil pushing handle through a soil pushing rod. When the soil sampling operation is completed, an operator holds the soil pushing handle with one hand and holds the handle on the soil drill rod with the other hand, and then drives the soil pushing handle close to the handle, so that the soil pushing block pushes the soil sample in the soil sampling bit out of the soil sampling bit. When the viscosity of the soil sample in the soil sampling bit is relatively large, it is difficult for the operator to drive the soil pushing handle close to the handle. Content of the Utility Model
[0003] The purpose of the utility model is to provide a soil pushing tooling for an undisturbed soil drill and a soil sampling device, aiming to solve the problem that it is difficult for an operator to drive the soil pushing handle close to the handle when the viscosity of the soil sample in the soil sampling bit is relatively large.
[0004] In a first aspect, an embodiment of the utility model provides a soil pushing tooling for an undisturbed soil drill, which includes a bracket, a pressure rod, a power shaft and a drive shaft. The bracket is used to be connected with the handle in the undisturbed soil drill so that the soil pushing handle in the undisturbed soil drill is located above the handle, and a vertically arranged threaded hole is provided on the bracket. The pressure rod is slidably connected with the bracket in the vertical direction, and the pressure rod is used to squeeze the soil pushing handle in the undisturbed soil drill downward. The power shaft is arranged in the threaded hole and is provided with an external thread that is threadedly connected with the threaded hole, and the power shaft is rotationally connected with the pressure rod. The drive shaft is perpendicular to the power shaft and fixedly connected with the power shaft.
[0005] The solution shown in the embodiment of the present application, compared with the prior art, when the viscosity of the soil sample in the soil sampling bit is relatively large, the handle in the undisturbed soil drill is connected with the bracket. At this time, the pressure rod is located above the soil pushing handle, and the soil pushing handle is located above the handle. The operator drives the power shaft to rotate through the drive shaft, so that the power shaft threadedly connected with the bracket drives the pressure rod to move downward, and the pressure rod squeezes the soil pushing handle toward the handle, so that the soil pushing handle approaches the handle. In this way, the soil pushing block can be made to push the soil sample in the soil sampling bit out of the soil sampling bit. Since the drive shaft is perpendicular to the power shaft, the operator can apply a large torque to the power shaft through the drive shaft to drive the power shaft to rotate, thereby avoiding the problem that it is difficult for the operator to drive the soil pushing handle close to the handle when the viscosity of the soil sample in the soil sampling bit is relatively large.
[0006] In combination with the first aspect, in a possible implementation, the earth-pushing tooling for the undisturbed soil sampler further includes a first limiting groove.

[0007] In combination with the first aspect, in a possible implementation, the earth-pushing tooling for the undisturbed soil sampler further includes a second limiting groove. The second limiting groove is slidably connected to the bracket, and the second limiting groove can slide close to or away from the first limiting groove. When the second limiting groove slides close to the first limiting groove, the second limiting groove can be sleeved outside the other end of the handle.
[0008] In combination with the first aspect, in a possible implementation, the bracket has a column, and the earth-pushing tooling for the undisturbed soil sampler further includes a sliding shaft. The sliding shaft is arranged along the sliding direction of the second limiting groove, and the sliding shaft slidably penetrates through the column and is fixedly connected to the second limiting groove.
[0009] In combination with the first aspect, in a possible implementation, the column is located on the side of the second limiting groove away from the first limiting groove, and the earth-pushing tooling for the undisturbed soil sampler further includes a compression spring. The compression spring is sleeved on the sliding shaft, and both ends of the compression spring are respectively abutted against the second limiting groove and the column.
[0010] In combination with the first aspect, in a possible implementation, the earth-pushing tooling for the undisturbed soil sampler further includes a pull ring. The pull ring is located on the side of the column away from the second limiting groove, and the pull ring is fixedly connected to the sliding shaft.
[0011] In combination with the first aspect, in a possible implementation, the earth-pushing tooling for the undisturbed soil sampler further includes a guide shaft. The guide shaft is vertically arranged, and the guide shaft is fixedly connected to the pressure rod and slidably penetrates through the bracket.
[0012] In combination with the first aspect, in a possible implementation, the power shaft can rotatably penetrate through the pressure rod, and two limiting portions protruding outward are provided on the side wall of the power shaft, and the two limiting portions are respectively attached to the bottom surface and the top surface of the pressure rod.
[0013] In combination with the first aspect, in a possible implementation, the middle part of the drive shaft penetrates through the power shaft.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0028] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
[0029] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 , and now the pushing tooling for the undisturbed soil drill provided by the present utility model will be described. The pushing tooling for the undisturbed soil drill includes a bracket 1, a pressure rod 2, a power shaft 3 and a drive shaft 4. The bracket 1 is used to connect with the handle 1101 in the undisturbed soil drill 110 so that the pushing handle 1102 in the undisturbed soil drill 110 is located above the handle 1101, and a vertically arranged threaded hole is provided on the bracket 1. The pressure rod 2 is slidably connected to the bracket 1 in the vertical direction, and the pressure rod 2 is used to squeeze the pushing handle 1102 in the undisturbed soil drill 110 downward. The power shaft 3 is inserted into the threaded hole and is provided with an external thread threadedly connected to the threaded hole, and the power shaft 3 is rotatably connected to the pressure rod 2. The drive shaft 4 is perpendicular to the power shaft 3 and fixedly connected to the power shaft 3.
[0030] The earth-pushing tooling for the undisturbed soil drill provided by the utility model, compared with the prior art, when the viscosity of the soil sample in the soil sampling bit 1104 is relatively high, connect the handle 1101 of the undisturbed soil drill 110 to the support 1. At this time, the pressure bar 2 is located above the earth-pushing handle 1102, and the earth-pushing handle 1102 is located above the handle 1101. The operator drives the power shaft 3 to rotate through the drive shaft 4, so that the power shaft 3 threadedly connected to the support 1 drives the pressure bar 2 to move downward. The pressure bar 2 then squeezes the earth-pushing handle 1102 towards the handle 1101, thereby making the earth-pushing handle 1102 approach the handle 1101. In this way, the earth-pushing block 1103 can be made to push the soil sample in the soil sampling bit 1104 out of the soil sampling bit 1104. Since the drive shaft 4 is perpendicular to the power shaft 3, the operator can apply a large torque to the power shaft 3 through the drive shaft 4 to drive the power shaft 3 to rotate, thereby avoiding the problem that it is relatively difficult for the operator to drive the earth-pushing handle 1102 to approach the handle 1101 when the viscosity of the soil sample in the soil sampling bit 1104 is relatively high.
[0031] In some embodiments, referring to Figure 1 , Figure 4 and Figure 5 , the earth-pushing tooling for the undisturbed soil drill further includes a first limiting groove 5. The first limiting groove 5 is used to sleeved outside one end of the handle 1101 to make the handle 1101 in a horizontal state. The first limiting groove 5 is fixedly connected to the support 1. The handle 1101 is connected to the support 1 through the first limiting groove 5. When the handle 1101 exits the first limiting groove 5, the connection with the support 1 is disconnected.
[0032] In some embodiments, referring to Figure 1 , Figure 3 , Figure 4 and Figure 5 , the earth-pushing tooling for the undisturbed soil drill further includes a second limiting groove 6. The second limiting groove 6 is slidably connected to the support 1. The second limiting groove 6 can slide close to or away from the first limiting groove 5. When the second limiting groove 6 slides close to the first limiting groove 5, the second limiting groove 6 can be sleeved outside the other end of the handle 1101. In this way, the second limiting groove 6 and the first limiting groove 5 cooperate to support the undisturbed soil drill 110.
[0033] In some embodiments, referring to Figure 1 and Figure 3 , the support 1 has a column 11. The earth-pushing tooling for the undisturbed soil drill further includes a sliding shaft 7. The sliding shaft 7 is arranged along the sliding direction of the second limiting groove 6. The sliding shaft 7 slidably penetrates through the column 11 and is fixedly connected to the second limiting groove 6. The sliding connection between the second limiting groove 6 and the support 1 is realized through the sliding cooperation between the sliding shaft 7 and the column 11.
[0034] In some embodiments, referring to Figure 1 andFigure 3 The column 11 is located on the side of the second limiting groove 6 away from the first limiting groove 5. The pushing tooling for the undisturbed soil sampler further includes a compression spring 8. The compression spring 8 is sleeved on the sliding shaft 7, and the two ends of the compression spring 8 are respectively abutted against the second limiting groove 6 and the column 11. The resilience of the compression spring 8 pushes the second limiting groove 6 towards the direction of the first limiting groove 5, so that the second limiting groove 6 cooperates with the first limiting groove 5 to clamp the handle 1101. In this way, the resistance for the handle 1101 to slide out of the first limiting groove 5 can be increased, so that the undisturbed soil sampler 110 is maintained at a preset position.
[0035] In some embodiments, refer to Figure 3 The pushing tooling for the undisturbed soil sampler further includes a pull ring 9. The pull ring 9 is located on the side of the column 11 away from the second limiting groove 6, and the pull ring 9 is fixedly connected to the sliding shaft 7. By pulling the sliding shaft 7 to slide through the pull ring 9, the second limiting groove 6 can be separated from the handle 1101, and then the handle 1101 can be separated from the first limiting groove 5. When the tooling is in an idle state, the sliding shaft 7 can be prevented from sliding out of the column 11 under the action of the resilience of the compression spring 8 through the limitation of the pull ring 9 by the column 11.
[0036] In some embodiments, refer to Figure 1 and Figure 2 The pushing tooling for the undisturbed soil sampler further includes a guide shaft 10. The guide shaft 10 is vertically arranged, and the guide shaft 10 is fixedly connected to the pressure bar 2 and slidably penetrates through the support 1. The sliding connection between the pressure bar 2 and the support 1 in the vertical direction is realized through the sliding fit between the guide shaft 10 and the support 1.
[0037] In some embodiments, refer to Figure 1 and Figure 2 The power shaft 3 can rotatably penetrate through the pressure bar 2, and two outwardly protruding limiting portions 31 are provided on the side wall of the power shaft 3. The two limiting portions 31 are respectively in contact with the bottom surface and the top surface of the pressure bar 2. Through the limitation of the two limiting portions 31 by the pressure bar 2, the relative displacement between the pressure bar 2 and the power shaft 3 in the vertical direction can be restricted, so that the power shaft 3 and the pressure bar 2 are rotatably connected together.
[0038] In some embodiments, refer to Figure 1 The middle part of the driving shaft 4 penetrates through the power shaft 3. The operator holds the two ends of the driving shaft 4 with both hands, and the operator's two hands respectively push and pull the power shaft 3 to rotate through the driving shaft 4.
[0039] Based on the same inventive concept, an embodiment of the present application further provides a soil sampling device, including a natural soil sampling drill 110, and further including the above-mentioned earth-pushing tooling for the natural soil sampling drill, so as to avoid the problem that it is difficult for an operator to drive the earth-pushing handle 1102 close to the handle 1101 when the viscosity of the soil sample in the soil sampling bit 1104 is relatively high.
[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
