Description

Technical Field

[0001] This utility model belongs to the technical field of underground coal mine equipment, specifically a tracked concrete mixing and paving machine for underground coal mines. Background Technology

[0002] In underground coal mine operations, the stability and safety of roadways are of paramount importance, and concrete paving is a key link in ensuring roadway stability and improving transportation efficiency. However, concrete paving operations in underground coal mines currently face many challenges.

[0003] Through research on the tunneling process in coal mines, it was found that after tunnel excavation, the road surface needs to be leveled and paved. The traditional paving process relies entirely on manual labor, using shovels for concrete mixing and leveling. This method is labor-intensive, consumes a lot of manpower, and has very low paving efficiency. Later, the use of traditional self-falling mixers and manual shoveling and leveling methods for paving has significantly improved efficiency compared to traditional manual paving. However, it still cannot meet the efficiency requirements of tunnel paving work and still suffers from high labor intensity and high manpower consumption. To address these issues, this utility model designs a tracked concrete mixing and paving machine for underground coal mines. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a tracked concrete mixing and paving machine for underground coal mines, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tracked concrete mixing and paving machine for underground coal mines, comprising a machine body, two chassis tracks at the bottom of the machine body, a hydraulic oil tank fixed at the top of the machine body, a bucket at the right end of the machine body, two reversing blocks fixed at the top of the bucket, a connecting disc fixed in the middle of the two reversing blocks, a chain fixed inside the connecting disc, a winding disc wound around the left end of the chain, a mixing drum fixed at the top of the left end of the machine body, a mixing shaft rotatably connected inside the mixing drum, several mixing blades outside the mixing shaft, a discharge port at the bottom of the mixing drum, a discharge chamber fixed at the bottom of the discharge port, a discharge arc plate slidably connected at the bottom of the discharge port, a connecting shaft at the front end of the discharge arc plate, and a bucket cylinder hinged to the top of the connecting shaft via a hinge ring.

[0006] Preferably, a controller is fixed to the top of the machine body, a hydraulic motor is provided at the front end of the hydraulic oil tank, and a battery is also fixed to the top of the machine body.

[0007] Preferably, a hinge plate is also fixed to the top of the machine body, and a hinge rod is hinged inside the hinge plate. The hinge rod is fixedly connected to the bucket, and the reversing block is hinged to the hinge plate through a rotating shaft. The rotating shaft of the reversing block is fixedly connected to the hinge rod.

[0008] Preferably, a positioning block is fixed to the top of the machine body, and two sets of guide wheels are hinged inside the positioning block. Each set of guide wheels is slidably connected to the chain. A winding motor is rotatably connected to the rear end of the winding disc, and the winding motor is fixedly connected to the machine body.

[0009] Preferably, a feed inlet is fixed to the top of the mixing tank, a hydraulic motor is fixed to the front end of the mixing tank, the shaft of the hydraulic motor is fixedly connected to the mixing shaft, several connecting plates are fixed to the outside of the mixing shaft, each connecting plate is fixedly connected to the mixing blades outside it, positioning plates are fixed to the front and rear ends of the mixing tank, a discharge connector is hinged to the bottom of each positioning plate, two discharge connectors are fixedly connected to each other through a discharge shaft, the front discharge connector is fixedly connected to the connecting shaft outside it, the top of the bucket cylinder is hinged to the mixing tank, the lower end of the discharge connector is fixedly connected to the discharge shaft, and the discharge arc plate can fit tightly against the discharge port.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model uses a bucket for loading concrete, a connecting disc for fixing a chain, and a winding motor to drive the winding disc to rotate, thereby driving the chain to wind around the outside of the winding disc. This causes the hinged rod to rotate around the reversing block, thus conveying the concrete inside the bucket to the feed inlet for easy mixing and subsequent paving work. It also automates the process, saving labor. The chain allows for a smaller bucket tilting height, making it suitable for small-sized coal mine tunnels and thus increasing the overall applicability of the integrated machine.

[0012] This invention uses the rotation of the mixing shaft to drive the mixing blades to rotate around the mixing shaft, thereby completing the mixing work and achieving concrete mixing accuracy. The cyclic rotation of the mixing blades drives the axial swing and axial movement of the concrete. To avoid the failure of the mixing blades due to friction, the overall mixing is driven by a hydraulic motor, which can effectively provide overload protection. The solution simplifies the connection of the mixing arm by using direct bolt connection, reducing the processing difficulty and processing cost.

[0013] This invention ensures the sealing of the discharge port while facilitating unloading through the discharge arc plate. The extension and retraction of the bucket cylinder drives the connecting shaft to rotate, which in turn drives the discharge connector to rotate, which in turn drives the discharge shaft to rotate, which in turn drives the discharge arc plate to rotate. This ensures the sealing of the discharge port while opening it, allowing the mixed concrete to be transported to the ground along the discharge chamber, facilitating subsequent paving work and improving mixing efficiency.

[0027] When using this integrated machine, the operator moves the entire machine to a coal mine roadway. At this time, the controller 101 controls the chassis tracks 102 to rotate, allowing the machine to move and change direction. When it reaches the desired paving location, the controller 101 controls the chassis tracks 102 to move the machine to the concrete location, shoveling concrete into the bucket 6.

When the operator observes that the concrete inside the mixing drum 3 has been mixed, the operator controls the bucket cylinder 5 to extend through the controller 101, thereby driving the connecting shaft 502 to rotate, which in turn drives the unloading connector 503 to rotate, which in turn drives the unloading shaft 507 to rotate, which in turn drives the unloading arc plate 504 to rotate, so that the concrete inside the mixing drum 3 is transported to the unloading chamber 506 through the discharge port 302, and thus the concrete is transported to the tunnel. At this time, the operator uses the controller 101 to move the entire integrated machine to the position of pouring concrete, and positions the bucket 6 at the left end, further leveling the bucket 6, and further moving the entire integrated machine to the right to scrape the concrete, thereby completing the paving work and leveling, thus ensuring the paving effect.

[0028] The working process of this utility model is as follows: When using this integrated machine, the operator controls the entire integrated machine to move to the coal mine roadway. At this time, the controller 101 can control the chassis track 102 to rotate, thereby driving the entire integrated machine to move and change direction. When it moves to the required paving position, the controller 101 controls the chassis track 102 to move the entire integrated machine to the concrete position, and then shovels the concrete into the bucket 6. At this time, the unloading arc plate 504 is in close contact with the discharge port 302. Further, the controller 101 controls the winding motor 608 to work. At this time, the hydraulic oil tank 2 provides the required hydraulic oil for the entire integrated machine. The hydraulic motor 201 can provide power for the entire integrated machine. Further, the winding motor 608 drives the winding disc 607 to rotate, thereby driving the chain 604 to wind around the winding disc 607, thereby transporting the concrete inside the bucket 6 to the mixing tank 3. Further, the operator adds the required water into the mixing tank 3. The controller 101 controls the hydraulic motor 4 to operate, thereby driving the mixing shaft 401 to rotate, which in turn drives the connecting plate 402 and the mixing blades 403 to rotate, thus mixing the concrete inside the mixing drum 3. When the operator observes that the concrete inside the mixing drum 3 has been mixed, the operator controls the bucket cylinder 5 to extend through the controller 101, thereby driving the connecting shaft 502 to rotate, which in turn drives the unloading connector 503 to rotate, which in turn drives the unloading shaft 507 to rotate, which in turn drives the unloading arc plate 504 to rotate, so that the concrete inside the mixing drum 3 is transported to the unloading chamber 506 through the discharge port 302, and thus the concrete is transported to the tunnel. At this time, the operator uses the controller 101 to move the entire integrated machine to the position of pouring concrete, and positions the bucket 6 at the left end, further leveling the bucket 6, and further moving the entire integrated machine to the right to scrape the concrete, thereby completing the paving work and leveling, thus ensuring the paving effect.
