Description

Technical Field

[0001] This application relates to the field of anchor bolt support technology, specifically to a resin cartridge blowing device. Background Technology

[0002] Rock bolt support is an engineering measure used to reinforce slopes, soil and rock masses, or surrounding rock in underground caverns. In rock bolt support, resin cartridges are an important anchoring agent. During construction, the resin cartridge is placed into the borehole, and then the anchor bolt is inserted. The resin cartridge cures quickly, rapidly bonding the anchor bolt to the borehole wall rock or soil, forming a reliable anchoring force. This rapid anchoring characteristic is particularly suitable for scenarios requiring rapid support, such as the initial support in tunnel construction, enabling timely prevention of surrounding rock deformation and collapse.

[0003] In the prior art, resin cartridges are conveyed by manual pushing or blowing devices. In the blowing device conveying, the blowing device needs to be connected to the conveying pipe, and the conveying pipe is connected to the anchor hole. After the resin cartridge is loaded into the blowing device, it is blown into the conveying pipe and then enters the anchor hole along the conveying pipe.

[0004] Existing blowing devices include blowing pipes and pipe fittings. Pipe fittings are used to connect the blowing pipes and the delivery pipes. However, in existing blowing devices, the blowing pipes are directly sleeved onto the pipe fittings to achieve the connection between the blowing pipes and the pipe fittings. However, this connection method has poor stability and airtightness, and is prone to air leakage, thus incurring costs. Furthermore, the pipe fittings have a simple structure, consisting only of connecting pipes, which makes the pipe fittings less robust and reliable, and prone to deformation, twisting, or detachment, thereby affecting the resin blowing efficiency and blowing quality.

[0005] Therefore, there is room for further improvement in existing resin cartridge blowing devices. Utility Model Content

[0006] In view of this, and in response to the technical problems of unstable pipe joint structure in the resin cartridge blowing device of the prior art, which leads to poor airtightness and weak connection of the blowing device, this application provides a resin cartridge blowing device, which includes a pipe joint connected to the delivery pipe. The pipe joint itself has a relatively stable structure, which can ensure the stability of the connection with the blowing mechanism, and is not easy to deform, twist or fall off, thereby ensuring the airtightness of the blowing device.

[0007] This application provides a resin cartridge blowing device, comprising:

[0008] The blowing mechanism is provided with a feeding channel and a blowing interface. The blowing interface is used to introduce high-pressure water and gas into the feeding channel, and the feeding channel is used to load resin cartridges.

[0009] A pipe joint, connected to the feed channel, is used to guide the resin cartridge into the anchor hole;

[0010] The pipe joint includes a resin pipe, a support sleeve, and a locking assembly, wherein the support sleeve is connected to the discharge end of the feed channel;

[0011] The end of the resin tube near the feed channel is connected to the blowing mechanism via the support sleeve;

[0012] The locking assembly is connected to the blowing mechanism at one end near the feeding channel and to the resin tube at the other end.

[0013] Compared with the prior art, the pipe joint of the resin cartridge blowing device of this application is connected to the blowing mechanism through a support sleeve and is provided with a resin tube, which provides a channel for the resin cartridge to pass through, thereby increasing the structural strength and improving the structural stability of the entire pipe joint. Furthermore, a locking component is provided, which is connected to the end of the resin tube away from the support sleeve and the other end to the blowing mechanism, thereby locking the resin tube relative to the blowing mechanism. Simultaneously, the end of the resin tube closest to the blowing mechanism is connected to the blowing mechanism through the support sleeve, and the portion extending in the discharge direction at a certain distance from the feed channel is secured by a locking mechanism. The component connects to the blowing mechanism, thereby giving the resin tube at least two connection points that are indirectly connected to the blowing mechanism. This ensures the stability of the connection between the resin tube and the blowing mechanism. This connection is achieved through a support sleeve and a locking assembly, which in turn ensures the stability of the connection between the resin tube and the support sleeve and locking assembly, making the pipe joint less prone to deformation and twisting. Under the action of the support sleeve and locking assembly, the entire pipe joint can be stably connected to the blowing mechanism, improving the connection strength between the pipe joint and the blowing mechanism, making it less likely to fall off, ensuring the airtightness of the connection between the pipe joint and the blowing mechanism, and ensuring the blowing efficiency of the resin cartridge blowing device.

[0014] Preferably, the locking assembly includes:

[0015] A ferrule is fitted onto the resin tube to secure the resin tube to the locking assembly.

[0016] The locking nut is threaded at one end to the discharge end of the blowing mechanism and the other end is fitted onto the ferrule.

[0017] A limiting screw sleeve is threaded to the end of the locking screw sleeve away from the blowing mechanism. The limiting screw sleeve is used to limit the ferrule between the locking screw sleeve and the resin tube.

[0018] The axial length of the resin tube is greater than the axial length of the locking assembly.

[0019] In this embodiment, the locking sleeving is connected to the blowing mechanism, the ferrule is fitted onto the resin tube, and the limiting sleeving is fitted onto the resin tube, the ferrule, and the locking sleeving simultaneously. Through the threaded connection with the locking sleeving, the ferrule is pressed onto the resin tube, thereby realizing the connection between the locking sleeving and the resin tube, and subsequently realizing the connection between the resin tube and the blowing mechanism.

[0020] Preferably, the sleeve includes a first end face and a second end face, the first end face and the second end face being distributed along the axial direction;

[0021] The first end face is in contact with the inner wall surface of the locking screw sleeve, and the second end face is in contact with the inner wall surface of the limiting screw sleeve;

[0022] The angle between the first end face and the second end face is an obtuse angle.

[0023] In this embodiment, the two end faces of the ferrule are inclined, which causes the ferrule to move axially. This changes the action surface of the locking sleeve and the limiting sleeve on the ferrule, thereby changing the force on the ferrule in the direction perpendicular to the axis, so as to adjust the clamping force of the ferrule on the resin tube, and thus ensure the stable connection between the resin tube and the locking sleeve.

[0024] Preferably, the inner wall of the sleeve is provided with a rack, and the rack is provided in multiple ways, the racks being equally spaced along the axial direction;

[0025] The sleeve has an opening, and the opening has an angle θ with the axis, wherein 0°≤θ<90°.

[0026] In this embodiment, the rack on the ferrule can increase the friction with the resin tube, thereby increasing the connection stability between the ferrule and the resin tube; and after setting the opening, the inner diameter of the ferrule can be adjusted, and the size of the opening can change the inner diameter of the ferrule, thus improving the applicability of the ferrule; when the opening is inclined to the axial direction, the range of reduction of the inner diameter of the ferrule can be increased, thus improving the applicability of the ferrule.

[0027] Preferably, the support sleeve includes a mounting cylinder, and the resin tube is sleeved on the mounting cylinder;

[0028] The mounting cylinder is provided with a guide section at the end away from the blowing mechanism, and the outer diameter of the guide section gradually decreases along the discharge direction;

[0029] Wherein, the minimum outer diameter of the guide part is smaller than the inner diameter of the resin tube, and the maximum outer diameter of the guide part is larger than the inner diameter of the resin tube.

[0030] In this embodiment, the guide portion can guide the resin tube during installation, reducing the difficulty of installation.

[0031] Preferably, the locking nut includes a first threaded portion and a second threaded portion, the first threaded portion and the second threaded portion being distributed axially at a distance;

[0032] The first threaded portion is connected to the blowing mechanism, and the second threaded portion is connected to the limiting screw sleeve;

[0033] The locking nut has a mating part at one end near the ferrule, and the wall surface of the mating part fits against the outer wall surface of the ferrule.

[0034] In this embodiment, the two threaded portions are spaced apart to prevent the limiting sleeve from colliding with the blowing mechanism, thus providing a certain limiting effect.

[0035] Preferably, the blowing mechanism includes a mounting base, and the feeding channel is disposed on the mounting base;

[0036] The discharge end of the mounting base is provided with a limiting ring groove, and the support sleeve is provided with a limiting retaining ring. The limiting ring groove is used to accommodate the limiting retaining ring.

[0037] The inner diameter of the support sleeve is greater than or equal to the minimum diameter of the feed channel; wherein the width of the limiting ring is greater than the width of the limiting ring groove.

[0038] In this embodiment, the combination of the limiting ring groove and the limiting retaining ring can increase the connection area between the support sleeve and the mounting base, thereby improving the connection stability.

[0039] Preferably, the blowing mechanism further includes:

[0040] The mounting base is connected to the end of the mounting base away from the pipe joint and has a feed port that communicates with the feed channel;

[0041] A baffle, connected to the mounting base, is located between the feed inlet and the feed channel and is used to change the connection between the feed inlet and the feed channel.

[0042] A reset handle, connected to the baffle, is used to control the rotation of the baffle to disconnect the feed inlet from the feed channel;

[0043] The blowing interface is located on the mounting base.

[0044] In this embodiment, with the reset handle and the baffle working together, after the resin cartridge passes through the baffle and enters the feeding channel, the baffle can be controlled to close the feeding port under natural gravity to prevent external gas from entering the feeding channel, ensuring the sealing of the feeding channel, so that the resin cartridge can be smoothly blown into the anchor hole.

[0045] Preferably, the blowing mechanism further includes:

[0046] The mounting groove is located on the side of the mounting base facing the baffle and is recessed in the direction away from the baffle.

[0047] The buffer element, made of elastic material, is located in the mounting groove, with at least a portion exposed outside the mounting groove and in contact with the baffle.

[0048] The mounting groove includes multiple limiting slots, and the buffer is provided with multiple limiting rings, which are located within the limiting slots.

[0049] In this embodiment, the buffer can buffer the baffle and the mounting base, reduce the collision and wear between the baffle and the mounting base, and improve the service life; while the limiting slot and the limiting ring cooperate to increase the connection between the buffer and the mounting base.

[0050] Preferably, the buffer further includes a buffer section, which extends beyond the mounting groove and protrudes to the outside of the mounting base, and the side of the buffer section facing the baffle is an arched arc surface;

[0051] The limiting groove is arranged perpendicular to the axis, and the angle between the limiting ring and the axis is an acute angle.

[0052] In this embodiment, the surface of the buffer that contacts the baffle is an arched arc surface, which can increase the elasticity of the buffer and improve its buffering effect and sealing performance. The angle between the limiting ring and the axis is an acute angle, which makes the limiting ring and the limiting groove not parallel. This can increase the connection stability between the limiting ring and the limiting groove, making it difficult for the limiting ring to detach from the limiting groove and ensuring the connection stability between the buffer and the mounting base.

[0064] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0065] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0066] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0067] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 8 illustrate.

[0068] This application provides a resin cartridge blowing device (hereinafter referred to as the blowing device), which is used in the field of anchor bolt support to blow resin cartridges into the anchor hole, thereby assisting in the anchoring of the anchor bolt.

[0069] Specifically, such as Figures 1 to 4 , Figure 8 As shown, the blowing device includes a blowing mechanism 1 and a pipe joint 2. The blowing mechanism 1 is provided with a feeding channel 111 for loading resin cartridges. The blowing mechanism 1 is provided with a blowing interface 17 that communicates with the feeding channel 111. The blowing interface 17 is used to introduce high-pressure water and gas into the feeding channel 111, thereby blowing the resin cartridges in the feeding channel 111 into the anchor hole. The pipe joint 2 is connected to the discharge end of the feeding channel 111. The pipe joint 2 is provided with a material passage that communicates with the feeding channel 111. The pipe joint 2 is connected to the blowing mechanism 1, so that the resin cartridges can enter the pipe joint 2 from the feeding channel 111, and then the pipe joint 2 guides the resin cartridges to the anchor hole.

[0070] Among them, such as Figures 1 to 4 As shown, the pipe joint 2 includes a resin pipe 21, a support sleeve 22, and a locking assembly 23. The resin pipe 21, support sleeve 22, and locking assembly 23 are coaxially arranged with the feed channel 111, as shown. Figure 8 As shown, the resin tube 21, support sleeve 22, and locking assembly 23 are all tubular structures. The resin tube 21 is made of PE material and is a straight tube. The support sleeve 22 is a T-shaped tube structure. The support sleeve 22 is connected to the discharge end of the feed channel 111 of the blowing mechanism 1. The end of the resin tube 21 near the feed channel 111 is sleeved on the support sleeve 22 to achieve the connection between the resin tube 21 and the support sleeve 22. The end of the locking assembly 23 near the feed channel 111 is threaded to the blowing mechanism 1, and the end of the locking assembly 23 away from the feed channel 111 is connected to the resin tube 21. 21. In the extension direction along the discharge direction, at a certain distance from the feed channel 111, the part is connected to the blowing mechanism 1 by the locking assembly 23. This makes the connection point between the resin tube 21 and the support sleeve 22 spaced apart from the connection point between the resin tube 21 and the locking assembly 23. As a result, the resin tube 21 has at least two connection points that are indirectly connected to the blowing mechanism 1. This ensures the firmness and reliability of the connection between the resin tube 21 and the blowing mechanism 1, makes it difficult for the pipe joint 2 to fall off the blowing mechanism 1, ensures the airtightness of the blowing device, and thus ensures the blowing efficiency of the blowing device and avoids wasting air.

[0071] In the pipe joint 2, a resin pipe 21 is provided to provide a safe and stable transmission channel for the resin cartridge, which increases the support stability of the internal discharge channel of the pipe joint 2, making it less prone to deformation and twisting, so that the resin cartridge can be smoothly fed into the anchor hole.

[0072] Furthermore, the locking component 23 is described in more detail; such as Figures 4 to 8 As shown, the locking assembly 23 includes a collet 231, a locking screw sleeve 232, and a limiting screw sleeve 233 arranged coaxially. The collet 231, locking screw sleeve 232, and limiting screw sleeve 233 are all cylindrical structures; wherein, as... Figure 4 As shown, the ferrule 231 is fitted onto the resin tube 21, the locking screw 232 is fitted onto the ferrule 231, and the limiting screw 233 is located at the end of the locking screw 232 away from the blowing mechanism 1. The limiting screw 233 is fitted onto the locking screw 232, the ferrule 231, and the resin tube 21 simultaneously, so as to limit the ferrule 231 between the locking screw 232 and the resin tube 21, so that the ferrule 231 can be tightly fitted onto the resin tube 21 under the clamping force of the locking screw 232 and the limiting screw 233, so as to realize the connection between the resin tube 21 and the locking assembly 23.

[0073] Specifically, such as Figure 4 , Figure 7 As shown, the outer wall surface of the locking sleeve 232 is provided with a first threaded portion 2321 and a second threaded portion 2322, which are spaced apart axially. The first threaded portion 2321 is threadedly connected to the blowing mechanism 1, and the second threaded portion 2322 is connected to the limiting sleeve 233. Correspondingly, the blowing mechanism 1 is provided with a threaded connection portion that mates with the first threaded portion 2321, and the inner wall surface of the limiting sleeve 233 is provided with a threaded connection portion that mates with the second threaded portion 2322. In this embodiment, there is a gap between the first threaded portion 2321 and the second threaded portion 2322, which can limit the stroke and prevent the limiting sleeve 233 from colliding with the blowing mechanism 1, thus playing a certain limiting role.

[0074] Furthermore, a further description is given of card sleeve 231; such as Figure 4 , Figure 6As shown, the outer wall of the sleeve 231 is provided with a first end face 2311 and a second end face 2312. The first end face 2311 and the second end face 2312 are distributed axially at intervals. A spacer end face is provided between the first end face 2311 and the second end face 2312. The spacer end face is parallel to the axis. The angle between the first end face 2311 and the spacer end face is an obtuse angle. The angle between the second end face 2312 and the spacer end face is an obtuse angle. The wall thickness of the sleeve 231 gradually decreases from the spacer end face toward the first end face 2311 and the second end face 2312, so that the two ends of the sleeve 231 are thin and the middle is thick.

[0075] In this design, the first end face 2311 is in contact with the inner wall surface of the locking sleeve 232. Correspondingly, at the end near the sleeve 231, the inner wall surface of the locking sleeve 232 is provided with a mating part, the wall surface of which is in contact with the outer wall surface of the sleeve 231. That is, the inclination of the mating part is adapted to the inclination of the first end face 2311 to ensure the contact area between the first end face 2311 and the mating part. At the same time, the second end face 2312 is in contact with the inner wall surface of the limiting sleeve 233. Correspondingly, the inner wall surface of the limiting sleeve 233 is provided with a mating end face that mates with the second end face 2312. The inclination of this mating end face is adapted to the second end face 2312 to ensure the contact area between the first end face 2311 and the mating part. The contact area between the two end faces 2312 and the mating end face; In this embodiment, through the first end face 2311 and the second end face 2312, the limiting screw sleeve 233 can push the ferrule 231 to move axially toward the locking screw sleeve 232, thereby changing the size of the mating surface of the locking screw sleeve 232, the limiting screw sleeve 233 and the ferrule 231, and thus changing the magnitude of the pressing force on the ferrule 231 in the direction perpendicular to the axis, so as to adjust the pressing force of the ferrule 231 on the resin tube 21, so as to ensure that the ferrule 231 can always be tightly fitted with the resin tube 21, so as to ensure the connection stability of the resin tube 21 and the locking screw sleeve 232.

[0076] Among them, such as Figure 6 As shown, in the direction parallel to the first end face 2311, the length of the mating part is greater than the length of the first end face 2311, to ensure that the ferrule 231 can fully mate with the mating part and to increase the tightening adjustment range of the locking sleeve 232 on the ferrule 231. Similarly, in the direction parallel to the second end face 2312, the length of the mating end face is greater than the length of the second end face 2312.

[0077] Furthermore, to ensure the connection between the ferrule 231 and the resin tube 21, such as... Figure 6As shown, the inner wall of the ferrule 231 is provided with racks 2313. Multiple racks 2313 are provided and are evenly spaced along the axial direction. Grooves are formed between the racks 2313, so that the ferrule 231 contacts the resin tube 21 through the racks 2313. This increases the contact friction between the ferrule 231 and the resin tube 21, making the connection between the ferrule 231 and the resin tube 21 tighter and ensuring the connection stability between the ferrule 231 and the resin tube 21.

[0078] like Figure 8 As shown, the sleeve 231 has an opening 2314 that penetrates the inner and outer walls of the sleeve 231. The opening 2314 is located at both ends of the sleeve 231 along its axial direction, so that the sleeve 231 has a sheet-like structure, but it has a tendency to automatically curl and always maintains a cylindrical structure. In this embodiment, after the sleeve 231 has an opening 2314, it can provide compression during the process of the sleeve 231 being tightened and contracted, which is used to hold the resin tube 21 tightly. This makes the inner diameter of the sleeve 231 adjustable. By adjusting the width of the opening 2314, the inner diameter of the sleeve 231 can be changed, thereby increasing the applicability of the sleeve 231. Furthermore, by adjusting the inner diameter of the sleeve 231, the sleeve 231 can always be tightly fitted to the resin tube 21.

[0079] The opening 2314 has an angle θ with the axis, where 0°≤θ<90°; that is, the opening 2314 can be set parallel to the axis or inclined to the axis. Preferably, θ is 30°.

[0080] When the opening 2314 is inclined to the axial direction, the force direction of the sleeves 231 on both sides of the opening 2314 is inclined to the axial direction and not perpendicular to the axial direction when they come into contact. This changes the force direction between the sleeves 231 on both sides of the opening 2314 during the closing process, thereby reducing the force on the sleeves 231 in the direction perpendicular to the axial direction during the closing process, making the sleeves 231 less prone to deformation during compression. Furthermore, the sleeves 231 can be displaced along the inclined direction of the opening 2314, thereby increasing the amount of closing of the sleeves 231 and improving the applicability of the sleeves 231.

[0081] Furthermore, the support sleeve 22 is described in more detail; such as Figure 4 , Figure 7 , Figure 8 As shown, the blowing mechanism 1 includes a mounting base 11, and a feed channel 111 is disposed on the mounting base 11, as follows: Figure 4As shown, the mounting base 11 has a sleeve at one end facing the pipe joint 2, the pipe joint 2 is set inside the sleeve, and the support sleeve 22 is connected to the discharge end of the feed channel 111 of the mounting base 11, that is, the support sleeve 22 is set and connected to the bottom of the sleeve; wherein, the inner side wall of the sleeve is provided with a threaded connection part that mates with the locking screw sleeve 232.

[0082] Specifically, the support sleeve 22 includes a mounting part 222, a connecting ring, and a mounting cylinder 221. The connecting ring is a flat ring structure, and its inner diameter is greater than or equal to the minimum inner diameter of the feed channel 111. The inner diameter of the connecting ring is also greater than the outer diameter of the resin cartridge, so that the resin cartridge can pass smoothly through the support sleeve 22. The mounting part 222 is a cylindrical structure and is located on the side of the connecting ring facing the mounting base 11. The mounting cylinder 221 is a cylindrical structure and is located on the side of the connecting ring away from the mounting base 11. The support sleeve 22 is connected to the mounting base 11 through the mounting part 222, and the support sleeve 22 is connected to the resin tube 21 through the mounting cylinder 221, thereby connecting the resin tube 21 to the mounting cylinder 221 through the support sleeve 22.

[0083] The mounting base 11 is provided with a limiting annular groove 112, which is recessed away from the support sleeve 22. The limiting annular groove 112 is used to accommodate the mounting part 222, wherein the width of the mounting part 222 is slightly larger than the width of the limiting annular groove 112, so as to achieve a tight fit between the mounting part 222 and the limiting annular groove 112, so that the support sleeve 22 and the mounting base 11 are connected by an interference fit. Figure 7 As shown, the outer side of the mounting part 222 is chamfered so that the mounting part 222 can be smoothly inserted into the limiting ring groove 112 to ensure the connection between the sleeve 231 and the mounting base 11.

[0084] Among them, such as Figure 7 As shown, resin tube 21 is sleeved on mounting cylinder 221. Mounting cylinder 221 includes a guide portion 2211 and a limiting portion. The limiting portion is connected to mounting portion 222, and the guide portion 2211 is connected to the other end of the limiting portion. The inner diameters of the limiting portion and the guide portion 2211 are the same. Along the axial direction, the outer diameters of the limiting portion are the same, but the outer diameter of the guide portion 2211 gradually decreases along the discharge direction, so that the outer wall of the guide portion 2211 is an inclined surface to provide a guiding function. The outer diameter of the limiting portion is larger than that of the other portion. The outer diameter of the connection between the guide part 2211 and the limiting part is the same as the outer diameter of the limiting part. The minimum outer diameter of the guide part 2211 is smaller than the outer diameter of the limiting part and smaller than the inner diameter of the resin tube 21, so that the resin tube 21 can be smoothly fitted onto the guide part 2211. Under the guidance of the guide part 2211, it is gradually fitted onto the limiting part, so that the resin tube 21 and the ferrule 231 are connected by interference fit to achieve a limiting connection, thereby ensuring the firmness of the connection between the resin tube 21 and the ferrule 231.

[0085] In this embodiment, the setting of the limiting part makes the part where the mounting cylinder 221 and the resin tube 21 are interference-fitted longer, which can ensure the connection stability between the mounting cylinder 221 and the resin tube 21.

[0086] Based on any of the above embodiments, the blowing mechanism 1 will be further described; such as Figures 1 to 8 As shown, the blowing mechanism 1 also includes a mounting base 12, a baffle 15, a reset handle 16, and a mounting plate 13. The mounting base 12 is connected to the side of the mounting seat 11 away from the pipe joint 2, and the mounting plate 13 is connected to the side of the mounting base 12 away from the mounting seat 11. That is, the mounting plate 13, the mounting base 12, the mounting seat 11, and the pipe joint 2 are connected in sequence.

[0087] Among them, such as Figure 4 , Figure 8 As shown, the mounting plate 13 is connected to the mounting base 12 by bolts or screws, and the mounting base 12 is connected to the mounting seat 11 by bolts or screws.

[0088] like Figure 4 , Figure 8 As shown, the mounting plate 13 is provided with a feeding inlet 131, the mounting base 12 is provided with a feeding port 121, and the feeding channel 111 is provided on the mounting base 11. The feeding inlet 131, the feeding port 121 and the feeding channel 111 are coaxially arranged. In the feeding direction, the inner diameter of the end of the feeding port 121 near the feeding channel 111 is smaller than the inner diameter of the end near the feeding inlet 131, but the minimum diameter of the feeding port 121 is larger than the outer diameter of the resin cartridge. This makes the channel formed by the feeding inlet 131 and the feeding port 121 narrow inward toward the feeding channel 111. The opening 2314 of this channel is relatively large, which makes it more convenient and faster for the staff to place the resin cartridge. The feeding port 121 has a guiding function, which can concentrate and guide the resin cartridge into the feeding channel 111.

[0089] Furthermore, such as Figure 4 , Figure 8As shown, baffle 15 is rotatably connected to mounting base 12, and baffle 15 is located on the side of mounting base 12 facing mounting base 11. Baffle 15 is disposed in feed channel 111, and reset handle 16 passes through mounting base 12 and is connected to baffle 15. The area of ​​baffle 15 is larger than that of feed inlet 121. Baffle 15 is located between feed inlet 121 and feed channel 111, and is used to change the communication relationship between feed inlet 121 and feed channel 111. That is, when baffle 15 is not in contact with mounting base 12, feed inlet 121 is connected to feed channel 111. The resin cartridge can pass through the inlet 121 from the outside to enter the feed channel 111. When the baffle 15 is attached to the mounting base 12, the connection between the inlet 121 and the feed channel 111 is disconnected. Gas, liquid or resin cartridge in the feed channel 111 cannot flow out through the inlet 121, but can only enter the pipe joint 2 along the feed channel 111. This ensures the sealing of the entire blowing device, so that the resin cartridge can be smoothly blown into the anchor hole, and reduces gas consumption, improves blowing efficiency, reduces losses and saves costs.

[0090] In this embodiment, such as Figure 1 , Figure 8 As shown, the reset handle 16 includes a rotating shaft 161 and a gravity rod 162. The rotating shaft 161 passes through the mounting hole of the mounting base 12 and is connected to the baffle 15. The exposed end of the rotating shaft 161 is perpendicularly connected to the gravity rod 162. The baffle 15 is rotatably connected to the mounting base 12 through the rotating shaft 161. When the baffle 15 is subjected to force and rotates, the gravity rod 162 overcomes gravity and rotates synchronously with the baffle 15, and the feed inlet 121 is connected to the feed channel 111. When the baffle 15 is not subjected to force, the gravity rod 162 resets the baffle 15 under the action of gravity, thereby closing the connection between the feed inlet 121 and the feed channel 111.

[0091] like Figure 1 , Figure 3 As shown in this application, the blowing interface 17 is installed on the mounting base 11 and can communicate with the feeding channel 111. The blowing interface 17 is connected to a three-way connector, which is connected to the blowing interface 17, a high-pressure water source, and a high-pressure air source respectively. High-pressure gas can enter the feeding channel 111 through the blowing interface 17 and blow the resin cartridge into the anchor hole. High-pressure water can enter the blowing device through the blowing interface 17 to flush the resin winding guide channel in the blowing device. This can effectively prevent residual drug from clogging the pipeline after the resin cartridge breaks. In addition, flushing the pipeline with water can play a certain lubricating role, which can reduce resistance and facilitate the blowing of the resin cartridge.

[0092] Based on any of the above embodiments, the blowing device will be further described; such as Figure 4 , Figure 5 , Figure 8As shown, the blowing device also includes a buffer 14. The mounting base 12 has a mounting groove 113 on the side facing the baffle 15. The mounting groove 113 is recessed in the direction away from the baffle 15. The mounting groove 113 has an annular structure. The buffer 14 has an annular ring structure. The buffer 14 is at least partially disposed in the mounting groove 113, and at least part of the buffer 14 is exposed outside the mounting groove 113 and abuts against the baffle 15. The buffer 14 is made of elastic material and has a certain elastic recovery force. It can play a buffering and shock-absorbing role when the baffle 15 collides with the mounting base 12, so as to avoid collision and wear between the baffle 15 and the mounting base 12 and improve the service life of the blowing device. It can also play a buffering role to prevent gas from leaking out from the gap between the baffle 15 and the mounting base 12.

[0093] Specifically, such as Figure 5 , Figure 8 As shown, the mounting groove 113 includes a basic groove and a limiting groove 1131. The basic groove has a roughly rectangular cross-section. Multiple limiting grooves 1131 are provided and are located in the middle of the mounting groove 113. The multiple limiting grooves 1131 are distributed at intervals along the axial direction. In the direction perpendicular to the axial direction, the length of the limiting groove 1131 is greater than that of the basic groove, that is, the limiting groove 1131 protrudes towards both ends of the basic groove. Furthermore, the length extension direction of the limiting groove 1131 is perpendicular to the axial direction.

[0094] Correspondingly, such as Figure 5 As shown, the buffer 14 includes a base and retaining rings 141. The cross-section of the base is approximately rectangular. Multiple retaining rings 141 are positioned at the center of the base and are spaced apart axially. In the direction perpendicular to the axial direction, the length of the retaining rings 141 is greater than that of the base, meaning the retaining rings 141 protrude towards both ends of the base. Furthermore, the length extension direction of the retaining rings 141 is perpendicular to the axial direction. When the buffer 14 is installed in the mounting groove 113, the base is inserted into the base groove, and the retaining rings 141 are inserted into the retaining grooves 1131, achieving a multi-point limiting connection between the buffer 14 and the mounting groove 113. The combined action of the retaining rings 141 and the retaining grooves 1131 limits the axial displacement of the buffer 14, ensuring a stable and secure connection between the buffer 14 and the mounting base 12.

[0095] Furthermore, in another optional embodiment of this application, such as Figure 5As shown, the angle between the length extension direction of the limiting ring 141 and the axial direction is an acute angle, which means that the length extension direction of the limiting ring 141 does not coincide with the length extension direction of the limiting groove 1131, and there is an angle between them. This acute angle is set between 40° and 60°, preferably 50°. Furthermore, the limiting ring 141 is inclined towards the baffle 15. When the buffer member 14 is subjected to an axial pulling force towards the baffle 15, the limiting ring 141 can decompose the axial force and only transmit part of the force to the limiting groove 1131, thereby making it difficult for the buffer member 14 to fall out of the mounting groove 113. In addition, since the limiting ring 141 is inclined towards the baffle 15, when the buffer member 14 is inserted into the mounting groove 113, the inclined surface of the limiting ring 141 plays a certain guiding role, so as to quickly and smoothly insert the buffer member 14 into the mounting groove 113, which simplifies assembly.

[0096] Furthermore, such as Figure 5 As shown, a buffer portion 142 is provided at one end of the base part that extends beyond the mounting groove 113 and protrudes into the mounting base 12. The buffer portion 142 protrudes outside the mounting base 12 and acts between the baffle 15 and the outer wall of the mounting base 12. The cross-section of the buffer portion 142 is an arched structure, and the side of the buffer portion 142 facing the baffle 15 is an arched arc surface. In the direction perpendicular to the axis, the width of the buffer portion 142 is greater than the width of the mounting groove 113, that is, both ends of the buffer portion 142 extend outward and fit against the mounting base 12.

[0097] like Figure 5 As shown, the side of the buffer part 142 facing the baffle 15 is the back, and the side of the buffer part 142 facing the mounting base 12 is the front. The center of the back of the buffer part 142 contacts the baffle 15, which is the first point of action. The two sides of the front of the buffer part 142 contact the mounting base 12, which are the second point of action and the third point of action, respectively.

[0098] Specifically, on the same axis, the projections of the first point of action and the second point of action do not overlap, while the projections of the second point of action and the third point of action overlap; in the same direction perpendicular to the axis, the projections of the first point of action, the second point of action, and the third point of action do not overlap; so that the first point of action, the second point of action, and the third point of action form a triangular structure, with the first point of action located on the center line between the second point of action and the third point of action.

[0099] When the baffle 15 applies force to the first point of action, the force is transmitted axially towards the second and third points of action. The buffer 14 decomposes the force applied by the baffle 15, playing a role in buffering and vibration reduction, and preventing the baffle 15 from colliding and wearing with the mounting base 12.

[0100] Meanwhile, since the buffer part 142 has an arched structure, it has a certain compression space when compressed under the action of force, which further plays a buffering role and can increase the contact area between the buffer part 142 and the mounting base 12 and the baffle 15, thereby further increasing the sealing effect between the baffle 15 and the mounting base 12 and preventing gas from leaking out from the gap between the baffle 15 and the mounting base 12.

[0101] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.
