Description

Technical Field

[0001] The utility model belongs to the technical field of drilling sampling, and more specifically, particularly relates to a coring device capable of pushing out core samples. Background Art

[0002] In the process of drilling and coring, asphalt or water-stable core samples are often stuck in the drill barrel in the existing coring machines used in the municipal inspection industry. It is inconvenient to remove the sampled core sample from the drill barrel after sampling. Therefore, the utility model designs an automatic core sample removal device for the coring machine used in the municipal inspection industry to solve the above problem.

[0003] After searching, for example, the patent number CN204877343U discloses a core sample ejection device for a coring machine drill, which is characterized by: comprising a screw that can be raised and lowered, a screw driving mechanism that drives the screw to rise and fall, a connecting piece that is rotatably connected to the lower end of the screw, and a circular steel plate that is movably connected to the lower end of the connecting piece; the diameter of the circular steel plate is smaller than the inner diameter of the drill bit, a through hole is provided at the upper end of the drill bit, the lower end of the screw and the connecting piece pass through the through hole at the upper end of the drill bit and extend into the inside of the drill bit; the screw driving mechanism is installed at the top of the drill bit. Compared with the prior art, it has the characteristics of saving time and labor, high work efficiency and high reliability.

[0004] The drilling and coring equipment in the above patents also has the following shortcomings:

[0005] The core sample ejection device in the above patent only introduces a device for ejecting the core sample in the drill bit, but does not introduce how the drill bit is connected to the drilling power, how to realize the ejection of the core sample in the drill bit without disassembling the drill bit after drilling the core sample, etc.

[0006] Moreover, the drilling and coring machines commonly used in the municipal inspection industry do not have the function of removing core samples. When the core sample is stuck in the drill barrel, the operator knocks the core sample out of the drill barrel by hammering the drill barrel. If the knocking force is too small, the core sample moves very slowly in the drill bit, and the coring efficiency is very low. If the knocking force is too large, the core sample is easily damaged or even broken, which not only wastes manpower and material resources, but also causes the drilled core sample data to be inaccurate or even unusable. In addition, long-term knocking accelerates the deterioration of the drill bit material, greatly shortening the service life of the drill bit. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a coring device capable of pushing out core samples, so as to solve the problem that the current commonly used coring machine for municipal inspection industry mentioned in the above background technology does not have the function of removing core samples. When the core sample is stuck in the drill tube, the operator knocks the core sample out of the drill tube by hammering the drill tube. If the knocking force is too small, the core sample moves very slowly in the drill bit, and the coring efficiency is very low. If the knocking force is too large, the core sample is easily damaged or even broken, which not only wastes manpower and material resources, but also causes the drilled core sample data to be inaccurate or even unusable. In addition, long-term knocking accelerates the deterioration of the drill bit material, greatly shortening the service life of the drill bit.

[0008] The purpose and effect of the coring device capable of pushing out core samples in the utility model are achieved by the following specific technical means:

[0009] A coring device capable of pushing out core samples comprises: a fixed seat; the fixed seat adopts a rectangular block structure; a mounting plate is fixedly arranged in the middle of the front side of the fixed seat; a connecting plate with a U-shaped structure is fixedly arranged in the upper middle of the front side of the fixed seat, and a through circular through groove structure is opened in the middle of the top of the connecting plate; a cylinder is fixedly arranged on the top of the connecting plate; a push rod with a cylindrical structure is transmission-connected to the bottom of the cylinder; a push plate with a circular plate-shaped structure is fixedly arranged at the bottom of the push rod.

[0010] Furthermore, the mounting plate adopts a Z-shaped plate structure, and a through-type circular through-groove structure is opened at the top of the rear side of the mounting plate; a hydraulic motor is fixedly arranged at the bottom of the front side of the mounting plate; a first transmission wheel is rotatably arranged at the front side of the top of the mounting plate, and the first transmission wheel is transmission-connected to the hydraulic motor; a rotating shaft is rotatably arranged in the circular through-groove at the top of the rear side of the mounting plate, and a bearing is arranged on the outside of the rotating shaft, a through-type circular through-groove structure is opened at the top of the rotating shaft, and through-type circular through-hole structures are opened on both sides of the outer wall of the rotating shaft.

[0011] Furthermore, a drill bit is fixedly arranged at the bottom of the rotating shaft, the inner diameter of the drill bit is larger than the diameter of the push plate, and the push rod passes through the circular through groove on the top of the drill bit; a second transmission wheel is installed on the outer side of the rotating shaft through a key, and the second transmission wheel is connected to the first transmission wheel through a transmission belt.

[0012] Furthermore, a water seal sleeve is fixedly arranged at the bottom of the circular through groove on the rear side of the mounting plate, and a through screw hole structure is opened on the outside of the water seal sleeve; a group of water seal rings with an annular structure are fixedly arranged on the upper and lower sides of the inner side of the water seal sleeve.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The push plate rod passes through the center hole of the rotating shaft and is connected to the cylinder shaft end through the connecting sleeve. The cylinder is ventilated, and the cylinder shaft extends, driving the push plate rod to push the core sample out. The thrust is evenly transmitted to the core sample through the circular steel plate, avoiding damage to the core sample caused by uneven force, improving the integrity of the core sample drilling, and at the same time, there is no need to use external force to knock, saving time and labor, easy to operate and use, and high degree of automation.

[0015] 2. The cooling water inlet is machined on the rotating shaft. The cooling water flows into the drill bit through the through hole in the rotating shaft, which plays a role of lubrication and cooling when coring. The cooling water seal adopts a water seal.

[0016] 3. The coring function and the core sample pushing function are integrated into one device. There is no need to disassemble any parts. The coring and core sample pushing functions can be completed by simply operating the buttons. The operation is convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0026] Embodiment 1:

[0027] As attached Figure 1 To Attachment Figure 6 As shown:

[0028] The utility model provides a coring device capable of pushing out a core sample, comprising: a fixed seat 1; the fixed seat 1 adopts a rectangular block structure; a mounting plate 2 is fixedly arranged in the middle of the front side of the fixed seat 1; a connecting plate 101 with a U-shaped structure is fixedly arranged in the upper middle of the front side of the fixed seat 1, and a through-type circular through groove structure is opened in the middle of the top of the connecting plate 101; a cylinder 102 is fixedly arranged on the top of the connecting plate 101; a push rod 103 with a cylindrical structure is transmission-connected at the bottom of the cylinder 102; and a push plate 104 with a circular plate-shaped structure is fixedly arranged at the bottom of the push rod 103.

[0029] Among them, the mounting plate 2 adopts a Z-shaped plate structure, and a through-type circular through groove structure is opened at the top of the rear side of the mounting plate 2; a hydraulic motor 201 is fixedly arranged at the bottom of the front side of the mounting plate 2; a first transmission wheel 202 is rotatably arranged on the front side of the top of the mounting plate 2, and the first transmission wheel 202 is transmission-connected with the hydraulic motor 201; a rotating shaft 203 is rotatably arranged in the circular through groove at the top of the rear side of the mounting plate 2, and a bearing is arranged on the outside of the rotating shaft 203, a through-type circular through groove structure is opened at the top of the rotating shaft 203, and through-type circular through hole structures are opened on both sides of the outer wall of the rotating shaft 203.

[0030] Among them, a drill bit 204 is fixedly set at the bottom of the rotating shaft 203, the inner diameter of the drill bit 204 is larger than the diameter of the push plate 104, and the push rod 103 passes through the circular through groove on the top of the drill bit 204; a second transmission wheel 205 is installed on the outer side of the rotating shaft 203 through a key, and the second transmission wheel 205 is connected to the first transmission wheel 202 through a transmission belt.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When performing drilling sampling operations, the first transmission wheel 202 is driven to rotate by the hydraulic motor 201, and the first transmission wheel 202 drives the second transmission wheel 205 to rotate through the transmission belt, thereby synchronously driving the rotating shaft 203 and the drill bit 204 to rotate, so that the drill bit 204 can perform coring operations. During the rotation of the rotating shaft 203 and the drill bit 204, since the push rod 103 passes through the circular through grooves on the top of the rotating shaft 203 and the drill bit 204, it will not affect the movement of the push rod 103 and the cylinder 102. After the coring is completed, the hydraulic motor 201 stops rotating, and the cylinder 102 is started to push the push rod 103 and the push plate 104 to move downward, and the core sample inside the drill bit 204 is pushed out by the push plate 104. The thrust is evenly transmitted to the core sample through the push plate 104, thereby avoiding damage to the core sample caused by uneven force, improving the integrity of the core sample drilling, and no external force is needed to knock, which saves time and effort, is easy to operate and use, and has a high degree of automation.

[0036] The specific usage and function of this embodiment are as follows:

[0037] In the utility model, a water inlet valve is installed at the screw hole on the outside of the water seal sleeve 206 through threaded cooperation. When coring, the water inlet valve is opened to allow cooling water to enter the interior of the drill bit 204 through the circular through hole on the outside of the rotating shaft 203, which has a lubricating and cooling effect on the interior of the drill bit 204, making it easier to remove the core sample. At the same time, the provision of two sets of water seal rings 207 can avoid leakage of cooling water.
