Description

Technical Field

[0001] This application relates to the field of archaeological equipment technology, and more particularly to an archaeological excavator. Background Technology

[0002] In archaeological exploration, the Luoyang shovel is a specially designed drilling and excavation tool. Its components include a shovel head and a shovel handle. The shovel handle can usually be connected in sections to measure the depth of soil layers. When extended, it can be driven into the ground to a depth of more than ten meters. It is mainly used for archaeological exploration. The shovel head is driven into the ground and then lifted up. By observing the color, texture, and inclusions of the soil at the shovel head, the state of the soil layer can be determined. In this way, information such as the strata, geology, and inclusions of the fill soil of the site can be obtained, so as to clarify the extent of the site.

[0003] However, the existing Luoyang shovels generally use threaded connections between the shovel handle and the shovel head, as well as between adjacent sections of the shovel handle. This makes the installation and disassembly of the Luoyang shovels quite troublesome and laborious. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this application is to provide an archaeological excavator that makes it easier to disassemble and assemble the shovel head and shovel bar, as well as the adjacent shovel bar sections, thereby improving the ease of disassembly and assembly and labor-saving of the excavator.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] An archaeological excavator includes a shovel head and several shovel handles, and also includes:

[0007] A connector for connecting the shovel head and the shovel bar, and between shovel bars, the connector comprising:

[0008] A first connecting part and a second connecting part, wherein the end of the shovel head is equipped with one of the first connecting part or the second connecting part, and one end of the shovel bar is equipped with the first connecting part and the other end is equipped with the second connecting part;

[0009] The first connecting part includes:

[0010] First connecting post;

[0011] A sliding groove is formed on the circumferential side of the first connecting column;

[0012] The locking block is slidably connected to the sliding groove along the radial direction of the first connecting column;

[0013] A first driving element is used to control the radial movement of the first connecting post of the card block;

[0014] The second connecting part includes:

[0015] Second connecting post;

[0016] A connecting groove is formed in the second connecting post, and the first connecting post is fitted with the connecting groove;

[0017] A slot is formed on the wall of the connecting groove along the first direction. The first connecting part and the second connecting part are constrained by the cooperation between the card block and the slot in the axial direction of the first connecting post.

[0018] In one possible implementation,

[0019] The first connecting post has a first mounting groove on its peripheral side and a second mounting groove inside the first connecting post along its axial direction.

[0020] The first driving component includes;

[0021] A drive rod, one end of which is hinged in a first mounting slot;

[0022] A first connecting rope is disposed in a second mounting groove, and one end of the first connecting rope is fixed to the middle of the drive rod.

[0023] A second connecting rope, one end of which is fixed to the first connecting rope, and the other end of which is fixed to the locking block;

[0024] A first spring, one end of which is fixed to the side of the locking block near the axis of the first connecting column, and the other end of which is fixed to the groove wall of the sliding groove near the axis of the first connecting column.

[0025] In one possible implementation,

[0026] The first driving component further includes:

[0027] The second spring has one end fixed to the bottom of the second mounting groove and the other end fixed to the end of the first connecting rope away from the drive rod.

[0028] In one embodiment, the sliding grooves formed on the first connecting column are in multiple rows, with multiple grooves in each row.

[0029] In one embodiment, the plurality of sliding grooves in each row are arranged in a circular array about the axis of the first connecting post.

[0030] In one embodiment, the first connecting column includes a first column and a second column, the first mounting groove is formed in the first column, the sliding groove is formed in the second column, and the first column and the second column are threadedly connected.

[0031] In one embodiment, the end of the second column away from the first column has a first chamfer.

[0032] In one embodiment, the card block has a second chamfer, and the second chamfer is located on the side of the card block away from the first column.

[0033] Compared with the prior art, this application has the following advantages:

[0034] This application utilizes a connector to install either a first connecting part or a second connecting part on the shovel head, a first connecting part on one end of the shovel handle, and a second connecting part on the other end. During assembly, a first driving component controls a locking block to retract into a sliding groove. Then, a first connecting post is aligned with the connecting groove and inserted, and the first driving component engages the locking block in the groove. This utilizes the circumferential surface of the first connecting post and the connecting groove, as well as the engagement of the groove and the locking block, to constrain the first and second connecting parts radially and axially along the first connecting post, ensuring the stability of their connection. This achieves stable installation of the shovel head and handle, or between shovel handles, and the entire installation process is convenient and labor-saving. When disassembling the shovel head and handle, or between shovel handles, the first driving component retracts the locking block into the sliding groove, allowing for quick separation of the shovel head and handle, or between shovel handles. The disassembly process is also simple and labor-saving. Overall, this improves the convenience and labor-saving aspects of assembling and disassembling the shovel head and handle, and between shovel handles.

Detailed Implementation

[0047] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] Reference Figure 1 - Figure 7An archaeological excavator provided in this application includes a shovel head 100 and several shovel rods 200. The shovel head 100 and the shovel rods 200, as well as the shovel rods 200, are connected by a connector 300. The connector 300 includes a first connecting portion 310 and a second connecting portion 320. One of the first connecting portion 310 or the second connecting portion 320 is installed at the end of the shovel head 100. The first connecting portion 310 is installed at one end of the shovel rod 200, and the second connecting portion 320 is installed at the other end of the shovel rod 200. The first connecting portion 310 includes a first connecting post 311. A sliding groove 312 is formed on the peripheral side of the first connecting post 311. A locking block 313 is slidably connected in the sliding groove 312 along the radial direction of the first connecting post 311. The second connecting part 320 includes a second connecting post 321. A connecting groove 322 that matches the outer diameter of the first connecting post 311 is formed in the second connecting post 321. A slot 323 is formed on the groove wall of the connecting groove 322 along the radial direction of the second connecting post 321. When the first connecting post 311 is inserted into the connecting groove 322, the first connecting part 310 and the second connecting part 320 are constrained in the axial direction of the first connecting post 311 by the cooperation of the slot 323 and the slot 313.

[0049] The following is a further introduction based on specific usage scenarios. Here, one of the first connecting part 310 or the second connecting part 320 is first installed on the shovel head 100, the first connecting part 310 is installed at one end of the shovel bar 200, and the second connecting part 320 is installed at the other end of the shovel bar 200. When assembling the shovel head 100 and the shovel bar 200, as well as the shovel bar 200 and the shovel bar 200, the first drive member 314 first retracts the locking block 313 into the sliding groove 312. Then, the connecting post of the first connecting part 310 is inserted into the connecting groove 322 of the second connecting part 320. When the locking block 313 corresponds to the locking groove 323, the first drive member 314 makes the locking block 313 engage in the locking groove 323. This ensures that the first connecting post 311 and the second connecting post 321 are constrained in the axial direction, so that the first connecting part 310 and the second connecting part 320 are connected together, thereby making the shovel head 100 and the shovel bar 200 or the shovel bar 200 and the shovel bar 200 stably connected. When it is necessary to disassemble the shovel head 100 and the shovel bar 200 or the shovel bar 200 and the shovel bar 200, the first driving component 314 controls the locking block 313 to retract into the sliding groove 312, which removes the constraint between the first connecting part 310 and the second connecting part 320. This allows the shovel head 100 and the shovel bar 200 or the shovel bar 200 and the shovel bar 200 to be separated quickly, which is very simple and saves a lot of effort.

[0050] This application uses a connector 300 to install either a first connecting part 310 or a second connecting part 320 on the shovel head 100. The first connecting part 310 is installed at one end of the shovel bar 200, and the second connecting part 320 is installed at the other end of the shovel bar 200. During assembly, the first driving member 314 controls the locking block 313 to retract into the sliding groove 312. Then, the first connecting post 311 is aligned with the connecting groove 322 and inserted. The first driving member 314 then uses the locking block 313 to engage with the locking groove 323. In this way, the peripheral side of the first connecting post 311 and the connecting groove 322, as well as the locking groove 323 and the locking block 313, constrain the first connecting part 310 and the second connecting part 320 in the radial and axial directions along the first connecting post 311, ensuring the stability of their connection. This achieves stable installation between the shovel head 100 and the shovel bar 200, or between two shovel bars 200. The entire installation process is convenient and labor-saving. When disassembling the shovel head 100 and the shovel bar 200, or between the shovel bars 200, the first driving component 314 causes the locking block 313 to retract into the sliding groove 312, allowing for quick separation of the shovel head 100 from the shovel bar 200 and between the shovel bars 200. The disassembly process is relatively simple and labor-saving. Overall, this improves the convenience and labor-saving of assembling and disassembling the shovel head 100 from the shovel bar 200 and between the shovel bars 200.

[0051] Furthermore, refer to Figure 2 - Figure 6 A first mounting groove 400 is formed on the peripheral side of the first connecting post 311, and a second mounting groove 500 is formed inside the first connecting post 311 along its axial direction. The first driving member 314 includes a driving rod 3141 hinged in the first mounting groove 400, and a first connecting rope 3142 is provided in the second mounting groove 500, with one end of the first connecting rope 3142 fixed to the middle of the driving rod 3141. In addition, the first driving member 314 also includes a second connecting rope 3143, with one end of the second connecting rope 3143 fixed to the first connecting rope 3142 and the other end fixed to the locking block 313. A first spring 3144 is fixed to the side of the locking block 313 near the axis of the first connecting post 311, and the side of the first spring 3144 away from the locking block 313 is fixed to the groove wall of the sliding groove 312 near the axis of the first connecting post 311.

[0052] In specific usage scenarios, when it is necessary to control the retraction of the locking block 313 into the sliding groove 312, the drive rod 3141 is rotated, causing the movable end of the drive rod 3141 (i.e., the end away from the hinge end) to move away from the first mounting groove 400. This will pull the first connecting rope 3142 and simultaneously pull the second connecting rope 3143, thereby causing the locking block 313 to retract into the sliding groove 312. During this process, the first spring 3144 will be gradually compressed. When the drive rod 3141 is released, the elastic force of the first spring 3144 will cause the locking block 313 to move along the sliding groove 312 in a direction away from the axis of the first connecting post 311. This will pull the second connecting rope 3143 and the first connecting rope 3142, and cause the drive rod 3141 to rotate around its hinge axis until the movable end of the drive rod 3141 returns to the first mounting groove 400. By turning the drive rod 3141, the locking block 313 can be controlled to retract into the sliding groove 312. After releasing the drive rod 3141, the locking block 313 will extend out of the sliding groove 312.

[0053] Reference Figure 5 and Figure 6 As a specific embodiment of this application, the first driving member 314 further includes a second spring 3145, one end of which is fixed to the bottom of the second mounting groove 500, and the other end of which is fixed to the end of the first connecting rope 3142 away from the driving rod 3141.

[0054] Depending on the specific application scenario, the second spring 3145 can provide force to the first connecting rope 3142 along the axis of the first connecting post 311. Thus, when the drive rod 3141 is pried open and released, the second spring can make the reset of the drive rod 3141 smoother.

[0055] Reference Figure 3 and Figure 4 In one specific embodiment of this application, the sliding grooves 312 formed on the first connecting post 311 are arranged in multiple rows, with multiple grooves in each row. It should be understood that the number and distribution of the slots 323 on the second connecting post 321 should also correspond to the number and distribution of the sliding grooves 312, so that after the first connecting post 311 is inserted into the connecting groove 322, the locking blocks 313 in each sliding groove 312 are correspondingly inserted into a locking slot 323. In this way, the cooperation of multiple locking blocks 313 and locking slots 323 increases the contact area between the first connecting post 311 and the second connecting post 321, thereby increasing the connection strength between them, and further improving the connection stability of the connector 300 between the shovel head 100 and the shovel bar 200, or between two shovel bars 200.

[0056] Furthermore, the multiple sliding grooves 312 in each row are arranged in a circular array about the axis of the first connecting post 311. This not only ensures that the sliding grooves 312 opened on the first connecting post 311 are evenly distributed on the first connecting post 311, thus ensuring the overall structural strength of the first connecting post 311, but also makes the constraint force distribution of the first connecting post 311 and the second connecting post 321 more even after they are combined with the second connecting post 321.

[0057] Reference Figure 3 - Figure 6 As a specific embodiment of this application, the first connecting post 311 includes a first post 3111 and a second post 3112. A first mounting groove is formed in the first post 3111, and a sliding groove 312 is formed in the second post 3112. The first post 3111 and the second post 3112 are threadedly connected.

[0058] In accordance with specific usage scenarios, the first connecting post 311 is designed in the form of a first column 3111 and a second column 3112 to facilitate the installation of the first connecting rope 3142 and the second connecting rope 3143, and to ensure that the overall assembly of the first connecting post 311 is more convenient.

[0059] Reference Figure 3 - Figure 6 As a specific embodiment of this application, the second column 3112 has a first chamfer 600 at the end away from the first column 3111. The first chamfer 600 facilitates focusing when the first connecting column 311 is inserted into the connecting groove 322, thereby facilitating the assembly between the first connecting column 311 and the second connecting column 321.

[0060] Reference Figure 3 - Figure 6 In this specific embodiment of the present application, the locking block 313 has a second chamfer 700, and the second chamfer 700 is located on the side away from the first column 3111. When the first connecting column 311 is inserted into the connecting groove 322, and the locking block 313 moves down to the opening of the connecting groove 322, the force of the second connecting column 321 on the locking block 313 will cause the locking block 313 to move into the sliding groove 312. Therefore, during installation, it is not necessary to use the drive rod 3141 to retract the locking block 313 into the sliding groove 312 first, which improves the connection convenience of the first connecting column 311 and the second connecting column 321.
