Description

Technical Field

[0001] This utility model relates to the field of shotcrete equipment technology, specifically to a bagged material feeding device for a wet shotcrete machine. Background Technology

[0002] Wet shotcrete machines, also known as wet spraying machines, are industrial equipment that uses a wet spraying process to form a support layer of concrete or mortar. They are mainly used in mining area support, tunnel engineering, slope greening, and ecological restoration. In tunnel engineering, the wet shotcrete machine transports a concrete mix prepared in a certain proportion through pipelines and sprays it at high speed onto the surface to be sprayed, where it hardens to form a concrete support layer. With the development of shotcrete technology for tunnel support, various bagged concrete materials have emerged. The storage and construction of bagged concrete differs from traditional bulk materials. Currently, the bagged concrete material is usually manually transported and lifted to the height of the wet shotcrete machine's hopper before being poured into the hopper. However, due to the height of the wet shotcrete machine's hopper, there is a problem with the inconvenience of loading bagged concrete material, resulting in high labor intensity for workers. Summary of the Invention

[0003] This invention addresses the problem of inconvenient feeding of bagged concrete materials in existing technologies by providing a bagged material feeding device for a wet shotcrete machine. This device facilitates the feeding of bagged concrete materials by lifting them to the feed hood of a screw conveyor, which then transports the concrete materials into the hopper of the wet shotcrete machine. This saves manpower and reduces the labor intensity of workers. Furthermore, water can be added and mixed during the concrete material transportation process, thereby improving the mixing effect of the concrete materials.

[0004] To achieve the above objectives, the technical solution of this utility model is: a bagged material feeding device for a wet shotcrete machine, comprising a wet shotcrete machine frame, a bag-grabbing feeding mechanism at the rear end of the frame, and a screw feeding mechanism at the top of the frame. The bag-grabbing feeding mechanism is used to grab bagged concrete material and transfer it to the lower end of the screw feeding mechanism, which then conveys the concrete material upwards, causing it to fall into the hopper of the wet shotcrete machine.

[0005] The bag-gripping mechanism includes a support arm, a rotating arm, a lifting assembly, and a vacuum bag gripper. The support arm is vertically mounted on the top of the wet spraying machine frame. The rotating arm is rotatably connected to the upper end of the support arm. The lifting assembly is located on top of the rotating arm and connected to the vacuum bag gripper. The vacuum bag gripper is used to grip bagged concrete material. The lifting assembly can lift the bagged concrete material to a certain height. The rotating arm can rotate the bagged concrete material to the lower end of the spiral feeding mechanism.

[0006] The spiral feeding mechanism includes a spiral cylinder and a spiral feeding assembly rotatably disposed inside the spiral cylinder. A power component connected to the spiral feeding assembly is located at the upper end of the spiral cylinder. The spiral cylinder is inclined upwards and positioned at the top of the wet spraying machine frame. A discharge port is located at the bottom of the upper end of the spiral cylinder, and a feed port is located at the top of the lower end. A feed hood is fixedly installed at the feed port. Concrete material enters the spiral cylinder through the feed hood, and the power component drives the spiral feeding assembly to rotate, causing the concrete material to rotate upwards and discharge from the discharge port at the bottom of the upper end of the spiral cylinder.

[0007] A metering water supply mechanism is provided on one side of the spiral drum. The metering water supply mechanism includes a main water supply pipe and multiple water supply pipes connected to the main water supply pipe, with one end of each water supply pipe extending into the interior of the spiral drum. Water can be supplied to the spiral drum through the main water supply pipe and the water supply pipes, achieving the effect of adding water and mixing concrete materials during the conveying process of the spiral feeding assembly.

[0008] Furthermore, a column is fixedly installed at the top of the support arm, and the rotating arm includes a first rotating arm and a second rotating arm. Rotating arms one and two of the first rotating arm are each equipped with a rotating drum, and one end of the second rotating arm is equipped with a rotating shaft. The two rotating drums are rotatably connected to the column and the rotating shaft, respectively. The first and second rotating arms facilitate the rotation of the bagged concrete material gripped by the vacuum bag grabber to the feed hood at the lower end of the spiral drum.

[0009] Furthermore, a pulley seat is fixedly provided at the top of the other end of the second rotating arm, and a pulley is rotatably provided inside the pulley seat; the lifting assembly includes a lifting cylinder and a steel wire rope, and a cylinder support is provided at the bottom of the lifting cylinder, which is fixedly provided at the top of the second rotating arm. The lifting cylinder serves as the power source for lifting bagged concrete materials.

[0010] Furthermore, one end of the steel wire rope is connected to the piston end of the lifting cylinder, and the other end of the steel wire rope passes over the pulley and is connected to a mounting base. The mounting base is connected to the vacuum bag grabber, and a handrail is also provided on the mounting base. The piston end of the lifting cylinder moves in a telescopic motion, which, through the action of the steel wire rope and the pulley, drives the vacuum bag grabber to move up and down. The handrail allows the operator to push and pull the rotating arms one and two, causing them to rotate.

[0011] Furthermore, a support plate is rotatably mounted on the upper side of the feed hood, a baffle is vertically mounted on the lower end of the support plate, and a support rod is arranged below the support plate. The vacuum bag-grabbing machine can place bagged concrete material on the support plate so that workers can easily pour the bagged concrete material into the feed hood.

[0012] Furthermore, the two ends of the support rod are hinged to the feed hood and the support plate, respectively; the support plate has openings corresponding to the support rod, and the support rod supports the support plate so that the vacuum bag grabber can place the bagged concrete material on the support plate, and the support plate supports the bagged concrete material.

[0013] Furthermore, several mounting plates are arranged on one side of the spiral cylinder, and the upper part of the mounting plate has a strip-shaped hole. The water supply main pipe is provided with clamps corresponding to the mounting plates, and the clamps are detachably connected to the mounting plates. The mounting plates provide an installation position for the water supply main pipe, and the height of the water supply main pipe can be adjusted by the action of the clamps and the strip-shaped holes on the mounting plates.

[0014] Furthermore, a liquid filter and a main control valve are installed on the main water supply pipe, and a metering control valve is installed on the water inlet pipe. The liquid filter filters the water delivered to the spiral drum, and the main control valve controls the opening and closing of the main water supply pipe.

[0015] Furthermore, the top of the spiral cylinder is provided with multiple through holes spaced apart, and the water supply pipe has an "L"-shaped structure. The vertical part of the water supply pipe passes through the through holes and extends into the interior of the spiral cylinder. The through hole design facilitates the vertical part of the water supply pipe to extend into the spiral cylinder, thereby facilitating the delivery of water for mixing concrete materials into the spiral cylinder through the water supply pipe.

[0016] The beneficial effects of this utility model through the above technical solution are as follows: This utility model has a reasonable structure and good performance. It can facilitate the feeding of bagged concrete materials, lift the bagged concrete materials to the feed hood of the screw conveyor, and then transport the concrete materials to the hopper of the wet spraying machine by the screw conveyor, saving manpower and reducing the labor intensity of the workers. In addition, water can be added and stirred during the conveying of concrete materials, thereby improving the mixing effect of concrete materials.

[0017] This utility model's bag-grabbing and feeding mechanism can grab bagged concrete materials and rotate them to the feed hood at the lower end of the spiral drum. The vacuum bag grabber plays the role of grabbing the bagged concrete materials, and the lifting component can lift the vacuum bag grabber to a certain height, thereby achieving the effect of lifting the bagged concrete materials to a certain height. The handrails allow the operator to push and pull the rotating arms one and two, causing them to rotate and rotate the bagged concrete materials to the feed hood. This allows the spiral feeding mechanism to transport the concrete materials upwards, facilitating the feeding of bagged concrete materials, saving manpower, and reducing the labor intensity of the operators.

[0018] This utility model's spiral feeding mechanism is driven by a power component to rotate the spiral feeding assembly, causing the concrete material to rotate upwards and be discharged from the discharge port at the bottom of the upper end of the spiral cylinder. The support plate on one side of the feeding hood serves to support the bagged concrete material. The vacuum bag grabber can place the bagged concrete material on the support plate so that workers can pour the bagged concrete material into the feeding hood.

[0019] This utility model's quantitative water addition mechanism can deliver water for mixing concrete materials into the screw drum through the main water supply pipe and the water addition pipe. This enables the addition and mixing of water to the concrete materials during the conveying process of the screw feeding assembly, ensuring that the concrete materials and water are fully and evenly mixed, thereby improving the mixing effect of the concrete materials.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 7 As shown, a bagged material feeding device for a wet shotcrete machine includes a wet shotcrete machine frame 1. A bag-gripping feeding mechanism is located at the rear end of the frame 1, and a spiral feeding mechanism is located at the top. In this embodiment, the bag-gripping feeding mechanism is installed at the top rear end of the wet shotcrete machine frame 1. This mechanism can grab bagged concrete material and lift it to a certain height. Simultaneously, it can rotate the grabbed bagged concrete material to the upper end of the spiral feeding mechanism. The spiral feeding mechanism can then convey the concrete material upwards, causing it to fall into the hopper of the wet shotcrete machine, thus facilitating the feeding of bagged concrete material.

[0023] The bag-grabbing and feeding mechanism includes a support arm 2, a rotating arm, a lifting assembly, and a vacuum bag-grabbing machine 11. The support arm 2 is vertically mounted on the top of the wet spraying machine frame 1. The rotating arm is rotatably connected to the upper end of the support arm 2. The lifting assembly is mounted on the top of the rotating arm and connected to the vacuum bag-grabbing machine 11. In this embodiment, the vacuum bag-grabbing machine 11 grabs the bagged concrete material to be fed. The lifting assembly lifts the vacuum bag-grabbing machine 11 to a certain height, and the vacuum bag-grabbing machine 11 simultaneously lifts the bagged concrete material to a certain height. Then, the rotating arm can transfer the bagged concrete material to the lower end of the spiral feeding mechanism. The operator uses tools to cut open the bagged concrete material and pour it into the spiral feeding mechanism.

[0024] The spiral feeding mechanism includes a spiral cylinder 13 and a spiral feeding assembly 15 rotatably disposed inside the spiral cylinder 13. The upper end of the spiral cylinder 13 is provided with a power component 14 connected to the spiral feeding assembly 15. The spiral cylinder 13 is inclined upwardly and disposed on the top of the wet spraying machine frame 1. The bottom of the upper end of the spiral cylinder 13 is provided with a discharge port 16 and the top of the lower end is provided with a feed port. A feed hood 17 is fixedly disposed at the feed port. In this embodiment, both the front and rear ends of the spiral cylinder 13 are connected to support legs mounted on the wet shotcrete machine frame 1. The length of the support leg at the front end of the spiral cylinder 13 is greater than the length of the support leg at the rear end. The purpose of this is that the wet spiral cylinder 13 is installed at an angle on the wet shotcrete machine frame 1, ensuring that the spiral feeding mechanism can convey the concrete material upwards and allow the concrete material to fall into the hopper of the wet shotcrete machine. The power component 14 provides power for the rotation of the spiral feeding assembly 15. The power component 14 drives the spiral feeding assembly 15 to rotate inside the spiral cylinder 13, thereby achieving the effect of conveying the concrete material upwards. The power component 14 is a motor. The spiral feeding assembly 15 includes a spiral shaft rotatably mounted inside the spiral cylinder 13. Spiral blades are mounted on the spiral shaft. The output shaft of the motor is connected to the spiral shaft, and the output shaft of the motor drives the spiral shaft to rotate inside the spiral cylinder 13. The spiral shaft drives the spiral blades to rotate inside the spiral cylinder 13.

[0025] A metering water supply mechanism is provided on one side of the spiral cylinder 13. The metering water supply mechanism includes a main water supply pipe 24 and multiple water supply pipes 27 connected to the main water supply pipe 24. One end of each water supply pipe 27 extends into the interior of the spiral cylinder 13. In this embodiment, the main water supply pipe 24 can be directly connected to a faucet for water supply, or a water pump from a water storage device can be used to supply water to the main water supply pipe 24. Four water supply pipes 27 are connected at equal intervals on the main water supply pipe 24. Water is transported into the main water supply pipe 24 and then enters the four water supply pipes 27 respectively. The water supply pipes 27 then transport the water into the spiral cylinder 13, so that the concrete material in the spiral cylinder 13 is mixed with water during the upward conveying of concrete material by the spiral feeding assembly 15.

[0026] A column 201 is fixedly installed at the top of the support arm 2. The rotating arm includes a first rotating arm 3 and a second rotating arm 4. Both ends of the first rotating arm 3 are provided with rotating cylinders 301, and one end of the second rotating arm 4 is provided with a rotating shaft 401. The two rotating cylinders 301 are rotatably connected to the column 201 and the rotating shaft 401, respectively. In this embodiment, the column 201 is vertically fixed at the top of the support arm 2. The two rotating cylinders 301 are rotatably connected to the column 201 and the rotating shaft 401 through bearings. The first rotating arm 3 rotates relative to the support arm 2, which can synchronously drive the second rotating arm 4 to rotate. The second rotating arm 4 can drive the lifting assembly and the vacuum bag grabber 11 to rotate. The relative rotation of the second rotating arm 4 and the first rotating arm 3 can drive the lifting assembly and the vacuum bag grabber 11 to rotate, thereby facilitating the rotation of the bagged concrete material grabbed by the vacuum bag grabber 11 to the feed hood 17 at the lower end of the spiral drum 13.

[0027] A pulley seat 7 is fixedly installed at the top of the other end of the rotating arm 4, and a pulley 8 is rotatably installed inside the pulley seat 7. The lifting assembly includes a lifting cylinder 5 and a steel wire rope 9. A cylinder support 6 is provided at the bottom of the lifting cylinder 5, and the cylinder support 6 is fixedly installed at the top of the rotating arm 4. In this embodiment, the cylinder support 6 is bolted to the rotating arm 4, and the lifting cylinder 5 is installed at the top of the rotating arm 4 through the cylinder support 6. The lifting cylinder 5 serves as the power source for lifting the bagged concrete material, and the pulley 8 facilitates the lifting cylinder 5 to lift the vacuum bag grabber 11 and the bagged concrete material upwards.

[0028] One end of the steel wire rope 9 is connected to the piston end of the lifting cylinder 5, and the other end of the steel wire rope 9 passes around the pulley 8 and is connected to the mounting base 10. The mounting base 10 is connected to the vacuum bag grabber 11, and a handrail 12 is also provided on the mounting base 10. In this embodiment, the piston end of the lifting cylinder 5 extends, causing the vacuum bag grabber 11 to move downward through the action of the steel wire rope 9 and the pulley 8, so that the vacuum bag grabber 11 can grab the bagged concrete material. The piston end of the lifting cylinder 5 retracts, lifting the vacuum bag grabber 11 upward through the action of the steel wire rope 9. The vacuum bag grabber 11 simultaneously drives the bagged concrete material upward. The handrail 12 facilitates the worker to push and pull the rotating arm 3 and the rotating arm 4, causing the rotating arm 3 and the rotating arm 4 to rotate, thereby facilitating the rotation of the bagged concrete material grabbed by the vacuum bag grabber 11 to the feed hood 17.

[0029] A support plate 18 is rotatably mounted on one side of the upper part of the feed hood 17, and a baffle 19 is vertically mounted on the lower end of the support plate 18. A support rod 21 is arranged below the support plate 18. In this embodiment, the support plate 18 is rotatably connected to the feed hood 17 via a hinge. When feeding bagged concrete material, the support plate 18 can be unfolded and supported by the support rod 21. When not feeding bagged concrete material, the support rod 21 can be disassembled, allowing the support plate 18 to be folded so that unfolding the support plate 18 does not affect the normal operation of the wet shotcrete machine in the tunnel. The vacuum bag grabber 11 can place bagged concrete material on the support plate 18, which supports the bagged concrete material so that the workers can pour the bagged concrete material into the feed hood 17. There are two support rods 21 under the support plate 18. When the bagged concrete material is placed on top of the support plate 18, the baffle 19 blocks the bagged concrete material. Since the feed hood 17 and the support plate 18 are in an inclined state, the baffle 19 can prevent the bagged concrete material from sliding down.

[0030] The two ends of the support rod 21 are hinged to the feed hood 17 and the support plate 18, respectively; the support plate 18 has openings 20 corresponding to the support rod 21. In this embodiment, two hinge seats are installed at intervals on the upper outer side of the feed hood 17 and the bottom of the support plate 18. The two ends of the support rod 21 are hinged to the hinge seats on the upper outer side of the feed hood 17 and the bottom of the support plate 18, respectively, by means of pins. There are two openings 20. When the support plate 28 is in a folded state, the openings 20 correspond to the hinge seats on the feed hood 17, and the hinge seats are located inside the openings 20. The purpose of this is to facilitate interference between the support plate 28 and the hinge seats on the feed hood 17.

[0031] A plurality of mounting plates 22 are arranged on one side of the spiral cylinder 13. The upper part of each mounting plate 22 has a strip-shaped hole 2201. A clamp 23 corresponding to the mounting plate 22 is arranged on the main water supply pipe 24. The clamp 23 is detachably connected to the mounting plate 22. In this embodiment, there are two mounting plates 22 on one side of the spiral cylinder 13. The mounting plates 22 are vertically installed on the outer side of the spiral cylinder 13, providing an installation position for the main water supply pipe 24. The clamp 23 is bolted to the mounting plate 22. The bolt passes through the round hole and the strip-shaped hole 2201 on the clamp 23 in sequence, and is fixed with a nut, thereby fixing the main water supply pipe 24. The clamp 23 and the strip-shaped hole 2201 allow for adjustment of the height of the main water supply pipe 24, thereby adjusting the length of the water supply pipe 26 extending into the spiral cylinder 13.

[0032] A liquid filter 25 and a main control valve 26 are installed on the main water supply pipe 24, and a metering control valve 28 is installed on the water inlet pipe 27. In this embodiment, the liquid filter 25 filters the water supplied to the main water supply pipe 24, the main control valve 26 controls the opening and closing of the main water supply pipe 24, and the metering control valve 28 controls the opening and closing of the water inlet pipe 27. Both the main control valve 26 and the metering control valve 28 are manual valves. By controlling the opening degree of the metering control valve 28 and the main control valve 26, the effect of metering water is added to the spiral drum 13 is achieved.

[0033] The top of the spiral cylinder 13 has multiple through holes spaced apart. The water supply pipe 27 has an "L"-shaped structure, and the vertical part of the water supply pipe 27 passes through the through holes and extends into the interior of the spiral cylinder 13. In this embodiment, there are four through holes at the top of the spiral cylinder 13. The function of the through holes is to allow the vertical part of the water supply pipe 27 to extend into the interior of the spiral cylinder 13, thereby facilitating the delivery of water for mixing concrete materials into the spiral cylinder 13 through the water supply pipe 27. This enables the addition and mixing of water to the concrete materials inside the spiral cylinder 13 during the upward conveying of concrete materials by the spiral feeding assembly 15.

[0034] The working principle of this utility model is as follows: When feeding bagged concrete material, the operator first rotates the rotating arm 3 and rotating arm 4 by holding the handle, moving the vacuum bag grabber 11 above the bagged concrete material. Then, the piston end of the lifting cylinder 5 extends, causing the vacuum bag grabber 11 to move downward through the action of the wire rope 9 and pulley 8, and then the vacuum bag grabber 11 grabs the bagged concrete material. Then, the piston end of the lifting cylinder 5 retracts, lifting the vacuum bag grabber 11 upward through the action of the wire rope 9, and the vacuum bag grabber 11 simultaneously drives the bagged concrete material upward. The operator then rotates the rotating arm 3 and rotating arm 4 by holding the handle again, rotating the bagged concrete material grabbed by the vacuum bag grabber 11 onto the support plate 18 on one side of the feed hood 17. Then, the piston end of the lifting cylinder 5 extends, placing the bagged concrete material grabbed by the vacuum bag grabber 11 onto the top of the support plate 18.

[0035] Then, the workers used tools to cut open the bagged concrete material and poured it into the feed hood 17. The concrete material entered the screw drum 13 through the feed inlet. The power unit 14 was started, which drove the screw feeding assembly 15 to rotate inside the screw drum 13, conveying the concrete material upward. During the process of conveying the concrete material, water was supplied to the screw drum 13 through the conveying main pipe 24 and the water supply pipe 27. The control main valve 26 and the quantitative control valve 28 were opened, and the opening degree of the quantitative control valve 28 and the control main valve 26 was controlled according to actual needs. Water was added quantitatively to the screw drum 13 through the water supply pipe 27, so that the screw feeding assembly could add water and stir the concrete material while conveying it, so that the concrete material and water could be fully and evenly mixed. Finally, the mixed concrete material was discharged from the discharge port 16 at the bottom of the upper end of the screw drum 13 and fell into the hopper of the wet spraying machine.

[0036] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
