Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, and more specifically to a portable sampling shovel. Background Art

[0002] In the field of soil research, outdoor research teams generally carry shovels to take soil samples in order to determine the soil's physical properties such as bulk density, moisture and structure.

[0003] Traditional shovels, even smaller engineer shovels, are still not convenient to carry in backpacks or suitcases, and it is difficult for personnel to exert force with smaller shovels. For compacted soil, sampling is time-consuming and laborious, and consumes a lot of physical energy. Therefore, the utility model provides a portable sampling shovel. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a portable sampling shovel, which solves the problem that even a smaller engineer shovel in the prior art is still inconvenient to put into a backpack or a suitcase for carrying, and it is difficult for personnel to exert force with a small shovel. For soil with a relatively compact texture, the sampling process is time-consuming and laborious, and the physical exertion is relatively high.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A portable sampling shovel comprises a through-core connector, a shovel blade is fixedly connected to one side of the through-core connector, a hollow main rod is passed through and movably connected to the other side of the through-core connector, a clamping block is passed through and movably connected to the outer side of the through-core connector, a connecting block is fixedly connected to one side of the connecting block, a pair of springs are fixedly connected to one side of the connecting block, one end of the pair of springs is fixed to the outer side of the through-core connector, a clamping groove is provided on the outer circumferential surface of the hollow main rod, and the clamping groove matches the clamping block;

[0007] A secondary rod is embedded in one end of the hollow main rod, and four inclined spring pieces are fixedly connected to one end of the hollow main rod close to the secondary rod. The inner walls of the four inclined spring pieces are fixedly connected with damping layers and clamped on the outer circumferential surface of the secondary rod. The outer circumferential surface of the hollow main rod is threadedly connected with an internal threaded ring.

[0008] Furthermore, one side of the through-connecting piece is fixedly connected to an internally threaded connecting block, and one side of the internally threaded connecting block is threadedly connected to a pedal rod.

[0009] Furthermore, a chamber is provided in the auxiliary rod, and a cap is threadedly connected to one end of the auxiliary rod.

[0010] Furthermore, the outer circumferential surface of the internal threaded ring is provided with anti-slip grooves.

[0011] Furthermore, one end of the hollow main rod is fixedly connected to a limiting block, and the diameter of the limiting block is larger than the hole diameter of the through-connecting piece. Beneficial Effects

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] (1) This proposal uses the Luoyang shovel as a prototype to design a shovel blade, which can easily sample deeper soil layers and causes less damage to the soil surface, making it convenient to quickly repair it after sampling;

[0014] (2) When the sampling shovel of this scheme is carried as a whole, the shovel blade, the hollow main rod and the auxiliary rod can be retracted together, so that the overall volume can be greatly reduced, which is convenient for people to put it into a backpack or a suitcase for carrying. When it is used, the hollow main rod is first pulled out. After the hollow main rod is extended to the right position, the spring and the connecting block can drive the card block to be embedded in the card groove on the surface of the hollow main rod, so as to limit the hollow main rod. Then, the auxiliary rod is pulled. After the auxiliary rod is extended, the internal thread ring is rotated. The internal thread ring moves to one side during the rotation process, which can squeeze the four inclined spring pieces at the same time. The squeezed inclined spring pieces cooperate with the damping layer to clamp and limit the auxiliary rod. When the hollow main rod and the auxiliary rod are fully extended, people can exert better force when using it, which reduces the physical consumption of people and improves the efficiency of soil sampling.

[0015] (3) The extension length of the auxiliary rod of this solution is not fixed, and the extension length of the auxiliary rod can be adjusted to meet the needs of different people;

[0016] (4) This solution is provided with a pedal rod. Under normal circumstances, the pedal rod is stored in the chamber of the auxiliary rod for easy carrying. When encountering relatively compact soil, the pedal rod can be taken out and threadedly connected to the internal threaded connection block. When taking soil samples, the pedal rod can be used together with the feet of the personnel to exert force. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example

[0025] like Figure 1-5 As shown, a portable sampling shovel comprises a through-core connector 1, a shovel blade 2 is fixedly connected to one side of the through-core connector 1, a hollow main rod 3 is passed through and movably connected to the other side of the through-core connector 1, a clamping block 4 is passed through and movably connected to the outer side of the through-core connector 1, a connecting block 5 is fixedly connected to one side of the connecting block 4, a pair of springs 6 are fixedly connected to one side of the connecting block 5, one end of the pair of springs 6 are fixed to the outer side of the through-core connector 1, and a clamping groove 35 is provided on the outer circumferential surface of the hollow main rod 3, and the clamping groove 35 matches the clamping block 4;

[0026] A secondary rod 7 is embedded in one end of the hollow main rod 3, and four inclined spring pieces 31 are fixedly connected to one end of the hollow main rod 3 close to the secondary rod 7. The inner walls of the four inclined spring pieces 31 are fixedly connected with a damping layer 32 and clamped on the outer circumferential surface of the secondary rod 7. The outer circumferential surface of the hollow main rod 3 is threadedly connected with an internal threaded ring 33.

[0027] When the sampling shovel is carried as a whole, the shovel blade 2, the hollow main rod 3 and the auxiliary rod 7 can be retracted together, so that its overall volume can be greatly reduced, which is convenient for people to put it into a backpack or a suitcase for carrying. In specific use, the hollow main rod 3 is first pulled out. After the hollow main rod 3 is stretched to the right, the spring 6 cooperates with the connecting block 5 to drive the clamping block 4 to be embedded in the clamping groove 35 on the surface of the hollow main rod 3, so as to limit the hollow main rod 3. Then, the auxiliary rod 7 is pulled. After the auxiliary rod 7 is stretched, the internal threaded ring 33 is rotated. The internal threaded ring 33 moves to one side during the rotation, and can squeeze the four inclined spring pieces 31 at the same time. The squeezed inclined spring pieces 31 cooperate with the damping layer 32 to clamp and limit the auxiliary rod 7. When the hollow main rod 3 and the auxiliary rod 7 are fully stretched, people can exert force better when using it, reduce their physical exertion, and improve the sampling efficiency of the soil. The extension length of the auxiliary rod 7 is not fixed, and the extension length of the auxiliary rod 7 can be adjusted to meet the use needs of different people.

[0028] Among them, the shovel 2 is based on the Luoyang shovel. The shovel 2 can easily sample deeper soil and has less damage to the surface of the soil layer, making it convenient to quickly repair it after sampling.

[0029] like Figure 4-5 As shown, one side of the through-connector 1 is fixedly connected to an internal thread connection block 11, and one side of the internal thread connection block 11 is threadedly connected to a pedal rod 12;

[0030] A chamber 71 is defined in the auxiliary rod 7 , and a cap 8 is threadedly connected to one end of the auxiliary rod 7 .

[0031] Under normal circumstances, the pedal rod 12 is stored in the chamber 71 of the auxiliary rod 7, and the cap 8 is screwed on for easy carrying. When encountering relatively compact soil, the pedal rod 12 can be taken out and threadedly connected to the internal threaded connecting block 11. When taking soil samples, the pedal rod 12 can be used together with the feet of the personnel to exert force.

[0032] like Figure 3-4 As shown, the outer circumferential surface of the internal thread ring 33 is provided with anti-slip grooves 331 .

[0033] When in use, the anti-slip grooves 331 can increase the friction between the hand of the person and the internal thread ring 33 , thereby reducing the possibility of slipping when the person rotates the internal thread ring 33 .

[0034] like Figure 1 As shown, one end of the hollow main rod 3 is fixedly connected to a limiting block 34 , and the diameter of the limiting block 34 is larger than the hole diameter of the through-connecting member 1 .

[0035] During use, the limiting block 34 is used to prevent the hollow main rod 3 from falling off the through-connecting piece 1 directly when a person extends the hollow main rod 3 .

[0036] In summary, the specific working process of the present scheme is as follows: when the shovel as a whole is carried, the shovel blade 2, the hollow main rod 3 and the auxiliary rod 7 can be retracted together, so that its overall volume can be greatly reduced, which is convenient for people to put it into a backpack or a suitcase for carrying. In specific use, the hollow main rod 3 is first pulled out. After the hollow main rod 3 is extended to the right position, the spring 6 cooperates with the connecting block 5 to drive the clamping block 4 to embed into the clamping groove 35 on the surface of the hollow main rod 3, thereby limiting the hollow main rod 3, and then pulling the auxiliary rod 7. After the auxiliary rod 7 is extended, the internal threaded ring 33 is rotated. The internal threaded ring 33 moves to one side during the rotation process, and can squeeze the four inclined spring pieces 31 at the same time. The squeezed inclined spring pieces 31 cooperate with the damping layer 32 to clamp and limit the auxiliary rod 7. When the hollow main rod 3 and the auxiliary rod 7 are fully extended, people can exert force better when using it, which reduces their physical exertion and improves the efficiency of soil sampling.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
