[0001] The utility model relates to the technical field of rock and soil exploration, and in particular to a sampler which is convenient to assemble and disassemble. Background Art

[0002] Geotechnical engineering investigation refers to the activities of identifying, analyzing, and evaluating the geological, environmental characteristics and geotechnical conditions of the construction site and compiling investigation documents according to the requirements of the construction project. The purpose of geotechnical engineering investigation is to use testing means and methods to investigate, study, analyze and judge the construction site, study the geological conditions for the construction of various engineering buildings and the impact of construction on the natural geological environment; study the measures to ensure the strength and stability of the foundation and prevent it from unacceptable deformation when the foundation, base and superstructure work together; propose the bearing capacity of the foundation, provide the geotechnical engineering data required for foundation design and construction, and strengthen the foundation when necessary.

[0003] At present, rock and soil sampling is an indispensable task in geotechnical engineering investigation. The existing sampling machine is generally composed of a frame, a hydraulic cylinder, a motor and a drill bit, and the drill bit is fastened to the output end of the motor by screws. Since the drill bit is easily worn out after use, it needs to be replaced, and when replacing, tools are needed to remove the screws one by one. The disassembly method is relatively cumbersome and inconvenient to use. Utility Model Content

[0004] Based on the above description, the utility model provides a sampler that is easy to assemble and disassemble to solve the technical problems raised in the above background technology.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A sampling machine that is easy to assemble and disassemble, comprising:

[0007] Bracket;

[0008] A hydraulic cylinder is arranged on the bracket;

[0009] A motor connected to the bottom of the hydraulic cylinder;

[0010] A support block connected to an output end of the motor;

[0011] A connecting block, detachably connected to the bottom of the supporting block;

[0012] A drill bit connected to the bottom of the connecting block;

[0013] Among them, a clamping block is connected above the connecting block, a limiting groove is provided on the clamping block, a bidirectional screw rod is arranged inside the supporting block, locking blocks are respectively sleeved on both ends of the bidirectional screw rod, and the rotation of the bidirectional screw rod drives the locking block to enter or exit the limiting groove.

[0014] On the basis of the above technical solution, the present invention can also be improved as follows.

[0015] Furthermore, a sliding groove extending toward the inside of the support block is provided on the side of the support block, the bidirectional screw rod is arranged in the limiting groove, and the threads at both ends of the bidirectional screw rod are respectively sleeved with nut seats slidably connected to the limiting groove, and the locking block is fixedly connected to the nut seat.

[0016] Furthermore, one end of the bidirectional screw rod extending to the outside of the support block is connected to a handle, a positioning hole is provided on the side of the support block, a through hole is provided on the handle, and a connecting rod that can pass through the through hole is movably inserted in the positioning hole.

[0017] Furthermore, placement grooves are provided on both sides of the interior of the bracket, sliding rods are symmetrically arranged inside the placement grooves, sliding sleeves are provided on the outside of the sliding rods, support rods are connected between the sliding sleeves, fixing rods are connected to the bottom of both sides of the support rods, a limiting plate is provided at the bottom of the fixing rod, and a tension spring is connected between the limiting plate and the fixing rod.

[0018] Furthermore, a chassis is installed at the bottom of the hydraulic cylinder, the motor is arranged inside the chassis, and the support block is fixedly connected to the output end of the motor.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0020] The drill bit and the motor of the existing sampler are fastened together by screws. When disassembling, the screws need to be removed one by one, which is a rather cumbersome method. The utility model realizes quick locking and unlocking by driving the locking block and the limit groove to be plugged in and matched with each other through the bidirectional screw. In some embodiments, specifically, a bracket, a hydraulic cylinder, a motor, a support block, a connecting block, a clamping block, a clamping groove, a limit groove, a sliding groove, a bidirectional screw, a nut seat, a locking block, and a drill bit are set. When the handle is turned, the bidirectional screw can be rotated, and the nut seat connected to the external thread of the bidirectional screw can be moved in the horizontal direction. When the two nut seats move toward the middle at the same time, the limit groove at the clamping block loses the clamping force of the locking block, so that the connecting block and the drill bit can be quickly disassembled, thereby achieving the purpose of facilitating the quick disassembly and replacement of the drill bit.

[0021] The existing samplers are prone to tilting, shaking or swaying when drilling and sampling, and their drilling mechanisms are unstable. The utility model arranges a chassis, a placement slot, a slide rod, a sleeve, a support rod, a fixed rod and a limit plate. When the hydraulic cylinder is started to drive the chassis outside the motor to move downward, the support rods welded on both sides of the chassis drive the sleeve to move up and down outside the slide rod, thereby achieving the purpose of limiting the motor and the chassis when moving, preventing shaking during the drilling process, and the limit plate can protect the dust splashed by the drill bit when drilling.

DETAILED DESCRIPTION

[0027] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0029] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0030] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0031] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0032] A sampling machine that is easy to assemble and disassemble, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a bracket 1, a hydraulic cylinder 2 and a motor 3. The hydraulic cylinder 2 is installed at the top of the inner side of the bracket 1, and a chassis 17 is installed at the bottom of the hydraulic cylinder 2. The motor 3 is installed inside the chassis 17. The output end of the motor 3 is welded with a support block 4, and the bottom of the support block 4 is snap-connected with a connecting block 5. The top of the connecting block 5 is welded with a clamping block 6. The bottom of the support block 4 is provided with a clamping groove 7, and one side of the clamping block 6 is provided with a limiting groove 8. The inside of the support block 4 is provided with a slide groove 9, and the inside of the slide groove 9 is connected with a bidirectional screw rod 10 through a bearing. The external thread of the bidirectional screw rod 10 is connected with a nut seat, and the bottom of the nut seat is welded with a locking block.

[0033] A drill bit 13 is welded to the bottom of the connecting block 5, and the connecting block 5 and the supporting block 4 form a clamping structure through the clamping block 6 and the clamping groove 7, and the clamping block 6 and the supporting block 4 form a clamping structure through the locking block and the limiting groove 8. By turning the handle 14, the bidirectional screw rod 10 can be rotated, and the nut seat connected to the external thread of the bidirectional screw rod 10 can be moved in the horizontal direction. When the two nut seats move toward the middle at the same time, the limiting groove 8 at the clamping block 6 loses the clamping force of the locking block, so that the connecting block 5 and the drill bit 13 can be quickly disassembled, thereby achieving the purpose of facilitating the rapid disassembly and replacement of the drill bit 13.

[0034] See also Figure 2 and Figure 3It can be known that a handle 14 is welded to one end of the bidirectional screw rod 10 extending to the outside of the support block 4, a positioning hole 15 is opened on one side of the support block 4, and a connecting rod 16 extending into the positioning hole 15 is slidably connected to the inside of the handle 14. When the handle 14 is rotated to a certain position, the connecting rod 16 can be passed through the handle 14 to the inside of the positioning hole 15 to prevent the bidirectional screw rod 10 from rotating.

[0035] See also Figure 1 , Figure 2 and Figure 3 It can be seen that placement grooves 18 are opened on both sides of the interior of the bracket 1, and a slide rod 19 is welded inside the placement groove 18. A slide sleeve 20 is sleeved on the outside of the slide rod 19, and a support rod 21 is welded between the slide sleeves 20 on both sides. A fixed rod 22 is welded to the bottom of both sides of the support rod 21. A limit plate 24 is set at the bottom of the fixed rod 22, and a tension spring 23 is welded between the limit plate 24 and the fixed rod 22. When the hydraulic cylinder 2 starts to drive the chassis 17 outside the motor 3 to move downward, the support rods 21 welded on both sides of the chassis 17 drive the slide sleeve 20 to move up and down outside the slide rod 19, thereby achieving the purpose of facilitating the limiting of the motor 3 and the chassis 17 when moving.

[0036] The working principle of the utility model is as follows: when using the sampler which is convenient for assembly and disassembly, the bidirectional screw rod 10 can be rotated, and the nut seat connected by the external thread of the bidirectional screw rod 10 can be moved in the horizontal direction. When the two nut seats move toward the middle at the same time, the limit groove 8 at the clamping block 6 loses the force of the locking block, so that the connecting block 5 and the drill bit 13 can be quickly disassembled, thereby achieving the purpose of facilitating the rapid disassembly and replacement of the drill bit 13. When the hydraulic cylinder 2 starts to drive the chassis 17 outside the motor 3 to move downward, the support rods 21 welded on both sides of the chassis 17 drive the sliding sleeve 20 to move up and down outside the sliding rod 19, thereby achieving the purpose of facilitating the motor 3 and the chassis 17 to limit the movement, preventing shaking during the drilling process, and the limit plate 24 can protect the dust splashed when the drill bit 13 is drilling.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
