[0023] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0024] A convenient-to-clean pneumatic grouting pump for mining includes a grouting pump 2 mounted on a base 1. A cleaning cover 3 is mounted on the base 1, positioned opposite the grouting pump 2. The opening of the cleaning cover 3 is opposite to the opening of the pump casing of the grouting pump 2. Two guide tubes 31 are symmetrically fixed on one inner wall of the cover 3. A drive shaft 32 located at its axis is installed inside the cover 3. A gear 4 and a cleaning assembly are mounted on the drive shaft 32. The cleaning assembly consists of a scraper 5 and a cleaning brush 6, arranged sequentially away from the inner wall. The scraper 5 has axially arranged grooves and teeth. The wheel 4 meshes and drives the cleaning brush 6. A push bucket 8 is provided at one end away from the scraper 5. The push bucket 8 is hollow inside and a telescopic rod 81 is installed. The telescopic rod 81 is fixedly connected to the connecting rod 9 at one end away from the push bucket 8. A receiving groove is provided at the other end of the base 1 opposite to the cover 3. A ball screw 10 is installed in the receiving groove. The ball screw 10 is threadedly connected to the slider 11. A bracket 12 is fixedly provided at the upper end of the slider 11. The grouting pump 2 is placed on the bracket 12. A guide rod 111 is fixedly provided on the side wall of the slider 11 at the position corresponding to the guide tube 31.

[0025] In other embodiments, the scraper 5 can be replaced with a soft scraper, and the cleaning brush 6 can be replaced with an ultrasonic cleaning device that uses high-frequency vibration to remove stubborn residues.

[0026] Furthermore, a first magnetic block 13 and a second magnetic block 14 are arranged vertically inside the cover 3. The first magnetic block 13 and the second magnetic block 14 are magnetically attracted. The first slider 11 is slidably connected to the slide 33 opened downward on the top wall of the cover 3. The first magnetic block 13 has a through groove at the end opposite to the slide 33. The second magnetic block 14 is fixedly connected to the rack 15 at the end opposite to the first magnetic block 13. The rack 15 is located above the gear 4.

[0027] Furthermore, a flat key 41 is provided at the center of gear 4, and a keyway is provided on the transmission shaft 32 corresponding to the position of the flat key 41. A spring is provided in the keyway, with one end of the spring fixed to the keyway and the other end fixed to the flat key 41.

[0028] In other embodiments, the flat key 41 can be replaced with an adjustable clutch structure, with a friction plate provided between the drive shaft 32 and the gear 4. The friction plate is fitted on the drive shaft 32 and contacts the inner ring of the gear 4. A spring adjusting screw is added to the clutch, and the contact degree of the friction plate is adjusted by changing the spring clamping force. The clamping mechanism is installed at the end of the drive shaft 32, and the clamping force of the friction plate is adjusted by adjusting the screw or the electronic control device. At the same time, the clamping force of the clutch is dynamically changed by adjusting the handle or the electronic control mechanism.

[0029] Furthermore, the telescopic rod 81 is provided with a locking block at the end facing the push barrel 8, and a locking groove is provided inside the push barrel 8 corresponding to the locking block.

[0030] Furthermore, the connecting rod 9 is a right-angle rod, which is fixedly connected to the telescopic rod 81 in the vertical direction, and the connecting rod 9 has an inclined surface set at the slot position in the horizontal direction.

[0031] Furthermore, feed slots are opened on the periphery of the pusher 8 corresponding to the feed direction of the connecting rod 9.

[0032] Furthermore, a contact rod 16 is fixedly connected to the connecting rod 9 at the position between the scraper 5 and the cleaning brush 6, and the contact rod 16 contacts the flat key 41 at the other end.

[0033] Working principle:

[0034] The grouting pump 2 is fixedly placed on the bracket 12, which is connected to the ball screw 10 via a slider 11. The slider 11 moves along the guide rod 111, and the ball screw 10 is driven by a motor to ensure that the grouting pump 2 can move smoothly to the designated position within the cleaning area. When the grouting pump 2 reaches the cleaning position, the drive shaft 32 starts to rotate, driving the gear 4 to operate. The gear 4 drives the scraper 5 to rotate along the inner wall of the grouting pump 2 through the tooth groove to initially scrape off the attached grout. Subsequently, the cleaning brush 6 further removes the residue to ensure that the inner wall is clean and smooth. When the telescopic rod 81 contacts the inner wall of the grouting pump 2, the telescopic rod 81 moves along the inner wall of the grouting pump 2. The feed groove of the push bucket 8 is displaced, which in turn causes the connecting rod 9 and the contact rod 16 to move. The contact rod 16 adjusts the power transmission state through the flat key 41. The contact rod 16 pushes the flat key 41 to move along the keyway, cutting off the power transmission between the gear 4 and the drive shaft 32. At the same time, the connecting rod 9 is displaced along the through groove, causing the first magnetic block 13 and the second magnetic block 14 to separate. The second magnetic block 14 moves vertically upward along the slide 33, and the first magnetic block 13 drives the rack 15 to move downward. The first magnetic block 13 and the rack 15 are driven by the gear 4 to limit and start / stop the scraper 5, ensuring the accuracy of the scraper 5's movement. When the telescopic rod 81 disengages from the inner wall of the grouting pump 2, the drive shaft 32 drives the cleaning brush 6 to continue rotating. At the same time, the motor drives the ball screw 10 to reverse, and the cleaning brush 6 cleans the residue cleaned by the scraper 5.
