Description

Technical Field

[0001] This utility model relates to the technical field of underground concrete mixing equipment, specifically a self-moving integrated feeding and mixing device. Background Technology

[0002] With technological advancements and continuous upgrades to mining equipment, coal mine equipment is becoming increasingly sophisticated and larger, requiring correspondingly larger spaces (including operating and maintenance spaces), especially in roadways with numerous pieces of equipment. This necessitates larger cross-section roadways to support the equipment. While increased roadway space facilitates mechanized concrete pavement paving in mine roadways, the unique conditions of underground coal mines mean that concrete pavement paving still relies on traditional manual methods. This involves transporting sand, gravel, and cement from the surface to the mine via rail, followed by manual unloading, mixing, water addition, paving, vibration, and leveling. This method is inefficient, labor-intensive, and largely relies on manual mixing based on experience, leading to poor uniformity of cement, sand, and water. This results in slow concrete setting or a short service life, making it difficult to achieve truly uniform mixing and compaction. Consequently, the concrete exhibits poor uniformity and flowability, resulting in low pavement strength and increased rework, thus raising production costs to some extent. Utility Model Content

[0003] The purpose of this invention is to provide an autonomously movable integrated feeding and mixing device that replaces the traditional manual labor for picking up sand and gravel materials and mixing concrete materials, thereby reducing labor intensity, improving construction efficiency, and solving the problems in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an autonomously movable integrated feeding and mixing device, including a frame, a walking track at the bottom of the frame, a support frame installed on the frame, a swingable belt conveyor hinged on the support frame, a material-pushing bucket installed at the front end of the belt conveyor, a support cylinder hinged between the belt conveyor and the front end of the frame, the piston rod of the support cylinder extending and retracting can drive the material-pushing bucket to rotate and rise, a cement hopper is also provided on the belt conveyor, a tilting mixing bucket is installed at the rear end of the frame, the mixing bucket can rotate to the bottom position of the material-dropping end of the belt conveyor, a water supply pipe is also installed at the end of the belt conveyor away from the material-pushing bucket, the water supply pipe can inject water into the mixing bucket, an oil pump assembly and an operating panel are also installed on the frame, the oil pump assembly is connected to each moving part of the device through an oil circuit, and the operating panel can control the start and stop of each moving part of the device. The material-feeding bucket is equipped with two sets of bearing seats arranged side by side. A material-feeding shaft is installed between the two sets of bearing seats. Two sets of symmetrically arranged augers are installed on the material-feeding shaft. A first sprocket is installed on the material-feeding shaft between the two sets of augers. The material-feeding bucket is equipped with a material-feeding motor. A second sprocket is installed on the output shaft of the material-feeding motor. A drive chain is installed between the second sprocket and the first sprocket. When the material-feeding motor is started, it drives the two sets of augers to rotate synchronously, transferring concrete aggregate to the belt conveyor. The cement hopper is equipped with several spaced-apart support plates. A horizontally arranged sleeve is installed on the cement hopper between the support plates. A movable pull rod is installed inside the sleeve. A handle is installed at the end of the pull rod that extends out of the sleeve. A long groove is opened on the sleeve.

[0016] The present invention describes a self-moving integrated feeding and mixing device, such as... Figure 1-4 As shown, the device includes a frame 1, which serves as the structural foundation of the entire device. At the bottom of the frame 1, there is a walking track 2, which can adapt to the complex ground environment in the underground mine roadway and provide the walking power for the whole machine.

[0017] A support frame 3 is installed on the frame 1, and a swingable belt conveyor 4 is hinged on the support frame 3. The belt conveyor 4 can transfer sand, gravel, and cement materials. A material-picking bucket 5 is installed at the front end of the belt conveyor 4. The material-picking bucket 5 can pick up sand and gravel materials on the roadway floor and transfer them onto the belt conveyor 4.

[0018] A support cylinder 6 is hinged between the belt conveyor 4 and the front end of the frame 1. The piston rod of the support cylinder 6 can extend and retract to drive the material-picking bucket 5 to rotate and rise, so as to adapt to the sand and gravel materials piled at different heights on the roadway ground, realize the uniform picking and feeding of sand and gravel materials, and after the height of the material-picking bucket 5 is adjusted, it will not affect the normal conveying of materials by the belt conveyor 4.

[0019] The belt conveyor 4 is also equipped with a cement hopper 7, which can be used to hold cement materials, so as to realize the mixed transfer of cement materials and sand and gravel materials on the belt conveyor 4.

[0020] A tilting mixing bucket 8 is installed at the rear end of the frame 1. The mixing bucket 8 can rotate to the bottom position of the material receiving end of the belt conveyor 4 to receive the material conveyed from the belt conveyor 4. A water supply pipe 9 is also installed at the end of the belt conveyor 4 away from the material feeding bucket 5. The water supply pipe 9 can inject water into the mixing bucket 8. The mixing bucket 8 thoroughly and evenly mixes the sand, cement and water inside to obtain concrete. After mixing is completed, the mixing bucket 8 is tilted to pour the concrete inside onto the ground to be paved.

[0021] The frame 1 is also equipped with an oil pump assembly 10 and an operating panel 11. The oil pump assembly 10 is connected to the various moving parts of the device through an oil circuit. The operating panel 11 can control the start and stop of the various moving parts of the device, providing the necessary power drive and operation control for the device. A flow meter and a solenoid ball valve can be installed on the water supply pipe 9. The flow meter can be used to achieve quantitative automatic water supply, or manual water replenishment can be controlled according to the degree of mixing.

[0022] When using a self-moving integrated feeding and mixing device to pave roads in a tunnel, the walking track 2 drives the entire device to the location where the road needs to be paved. The support cylinder 6 is controlled to extend and retract, driving the material-feeding bucket 5 to the height of the sand and gravel material piled on the road surface. Cement material is then placed into the cement hopper 7. The above material and water are then fed into the mixing bucket 8 for mixing via the belt conveyor 4. After mixing is completed, the mixing bucket 8 is flipped over, allowing the evenly mixed concrete inside to be poured onto the road surface.

[0023] Furthermore, in order to enable the material-picking bucket 5 to pick up sand and gravel materials onto the belt conveyor 4, such as... Figure 5 As shown, the feeding bucket 5 can be equipped with two sets of bearing seats 12 arranged side by side. A feeding shaft 13 is fitted between the two sets of bearing seats 12. Two sets of symmetrically arranged augers 14 are installed on the feeding shaft 13. Corresponding to the position of the augers 14, a hole is opened at the rear of the feeding bucket 5 to allow material to pass through. The front end of the belt conveyor 4 is located inside the hole. When the augers 14 rotate, they can push the sand and gravel material onto the rear conveyor belt.

[0024] To drive the material feeding shaft 13, a first sprocket 15 is installed on the material feeding shaft 13 between the two sets of augers 14. A material feeding motor 16 is provided on the material feeding bucket 5. A second sprocket 17 is installed on the output shaft of the material feeding motor 16. A transmission chain 18 is installed between the second sprocket 17 and the first sprocket 15. When the material feeding motor 16 is started, it can drive the two sets of augers 14 to rotate synchronously through the transmission of the sprocket and chain, and transfer the concrete aggregate to the belt conveyor 4.

[0025] Furthermore, bagged cement can be placed inside the cement hopper 7. To facilitate the discharge of the bagged cement, such as... Figure 6 and Figure 7 As shown, several spaced-apart support plates 19 can be installed inside the cement hopper 7, which can support the bagged cement. In order to break the packaging bag and allow the cement material inside to fall smoothly onto the belt conveyor 4, a horizontally arranged sleeve 20 is provided on the cement hopper 7 between the support plates 19. A movable pull rod 21 is installed inside the sleeve 20. A handle 22 is installed at one end of the pull rod 21 that extends out of the sleeve 20. A long groove 23 is opened on the sleeve 20. A cutter 24 that cooperates with the long groove 23 is provided on the pull rod 21. Pulling the handle 22 can move the cutter 24 in the long groove 23.

[0026] After the bagged cement is manually placed into the cement hopper 7, the bagged cement is placed on the support plate 19 and punctured by the cutter 24. Then, the worker pulls the handle 22 to move the lever 21 along the sleeve 20. The cutter 24 will cut a long strip opening in the packaging bag, allowing the cement material inside to fall onto the belt conveyor 4. Afterwards, the worker can take out the packaging bag after the material inside has fallen out.

[0027] Furthermore, in order to allow the mixing bucket 8 to tilt and move to the lower part of the conveyor belt 4 to receive the material to be mixed, and also to tilt and pour out the concrete material inside after mixing is completed, such as... Figure 8 As shown, a tilting frame 25 is hinged to the rear end of the frame 1, and a stirring bucket 8 is mounted on the tilting frame 25 via a rotary support 26. The stirring bucket 8 can rotate relative to the tilting frame 25.

[0028] A tilting cylinder 27 is also installed between the tilting frame 25 and the frame 1. The piston rod of the tilting cylinder 27 can drive the mixing bucket 8 to tilt. Since the mixing bucket 8 contains a large amount of concrete, in order to ensure the stability of the mixing bucket 8 during the tilting process, hinge seats 28 are provided on both sides of the tilting frame 25. A guide cylinder 29 is installed between each hinge seat 28 and the frame 1. When the tilting cylinder 27 performs the telescopic action, the guide cylinder 29 can telescopically follow the action of the tilting frame 25, thereby improving the stability of the tilting frame 25 during the tilting process.

[0029] The slewing support 26 allows the mixing bucket 8 to rotate horizontally relative to the tilting frame 25. The mixing bucket 8 is rectangular with its long and short sides arranged so that when receiving material from the belt conveyor 4, its short side is parallel to the width direction of the frame 1, thereby reducing the overall width of the device and its passage width in the tunnel. When the mixing bucket 8 is unloading material, its long side can rotate to be parallel to the width direction of the frame 1. After the mixing bucket 8 tilts, the concrete material inside can tilt down through its long side, thus improving the unloading efficiency of the concrete material.

[0030] Furthermore, such as Figure 9 As shown, a protective cover 30 can be installed on the conveyor frame at the material drop end of the belt conveyor 4. The water pipe 9 is fixed to the protective cover 30. The protective cover 30 ensures that the material enters the mixing hopper 8 during the falling process, preventing it from falling outside the mixing hopper 8. A scraper frame 31 is provided on the conveyor frame below the protective cover 30. A rubber plate 32 is bolted to the front end of the scraper frame 31. The rubber plate 32 can scrape off the residual material on the conveyor belt. Due to the elasticity of the rubber plate 32, it can scrape off the residual material while avoiding hard contact with the conveyor belt, thereby effectively extending the service life of the conveyor belt.

[0031] Furthermore, in order to achieve thorough and uniform mixing of the material within the mixing hopper 8, such as... Figure 10 As shown, a stirring shaft 33 can be installed inside the stirring hopper 8. Stirring motors 34 are installed at both ends of the stirring shaft 33 extending out of the stirring hopper 8. Several inclined stirring baffles 35 are also installed on the stirring shaft 33 inside the stirring hopper 8. The stirring operation is powerful, and the stirring baffles 35 allow the materials inside to be stirred and mixed more evenly.
