Description

Technical Field

[0001] This utility model belongs to the field of material suction machine technology, and specifically relates to a protective structure for a material suction machine. Background Technology

[0002] The suction feeder uses a vacuum pump to generate negative pressure, creating a vacuum environment in the suction pipe. Under atmospheric pressure, the material is sucked out of the material container and transported to the designated location.

[0003] Currently, Chinese utility model patent CN222555988U discloses a protective structure for an automatic material suction machine. However, since the material suction machine mainly sucks up powdery materials, which have poor flowability, and the suction pipe cannot move its position automatically, after the powdery material on the side of the material container closest to the suction pipe is sucked up, if the operator does not actively move the suction pipe to the other side, the powdery material on the other side will be far away from the suction pipe, resulting in lower suction force and ineffective suction into the material pipe. In addition, the poor flowability of the powdery material far away makes it difficult for it to automatically slide down to the vicinity of the suction pipe by gravity, thus affecting the material suction efficiency of the material suction machine. Utility Model Content

[0004] The purpose of this utility model is to provide a protective structure for a material suction machine. Its advantages are that it facilitates the automatic movement of the suction pipe for material suction, ensures the material suction efficiency of the material suction machine, and makes it easy to shake the material hopper to level the powdery material inside.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a protective structure for a suction machine, including a placement plate, a material cylinder is provided on the top of the placement plate, a slip ring is slidably connected to the top of the inner cavity of the material cylinder, a ring gear is fixedly sleeved on the outer surface of the slip ring, a threaded suction tube communicating with the inside of the material cylinder is bolted to one side of the inner surface of the slip ring, a disc gear rotatably connected to the material cylinder is meshed on one side of the surface of the ring gear, a motor is bolted to one side of the surface of the material cylinder, and the output end of the motor is fixedly connected to the disc gear.

[0006] The above technical solution involves rotating a slip ring inside the material cylinder, causing the threaded suction tube to reciprocate within the cylinder, thus sucking up powdery material from the inner edge. This allows for automatic movement of the suction tube, ensuring efficient material suction. By shaking the material cylinder and utilizing the spring force to reciprocate on the top of the placement plate, not only is any bulging of powdery material during feeding automatically leveled, allowing for more material to be stored in the cylinder, but it also avoids situations where the material is harmful to personnel and requires manual leveling, thus improving safety.

[0007] The present invention is further configured such that a placement groove is provided inside the placement plate, the material cylinder is placed inside the placement groove, and arc-shaped clamps that cooperate with the material cylinder are provided on both sides inside the placement groove. A spring that is fixedly connected to the placement plate is bolted to the side of the two arc-shaped clamps that are far apart from each other.

[0008] The above technical solution can not only automatically level out the bulges when adding powdered materials, allowing more material to be stored in the container, but also avoid situations where the materials are harmful to the human body and require manual leveling by staff, thus improving safety.

[0009] The present invention is further configured such that casters are installed at the four corners of the bottom of the placement plate, and a locking device is installed on one side of each of the four casters.

[0010] The above technical solution facilitates the movement of the placement plate, thereby making it easier to convey powdery materials inside the material cylinder.

[0011] The present invention is further provided that a cover plate is hinged to one side of the top of the material cylinder.

[0012] By adopting the above technical solution, the top of the barrel can be covered for protection when not in use, preventing dust and impurities from falling into the interior.

[0013] The present invention is further configured such that a sealing ring is bonded to the outer surface of the slip ring and is slidably connected to the inner surface of the material cylinder.

[0014] The above technical solution improves the sealing between the slip ring and the barrel, preventing powdery materials from entering the interior.

[0015] The present invention is further provided that an inverted conical block is welded to the bottom of the inner cavity of the barrel.

[0016] The above technical solution allows the powdery material inside the barrel to automatically slide to the bottom edge through the force of the inverted conical block, thus facilitating suction by the threaded suction tube.

[0017] The present invention is further provided that a telescopic rod is bolted to the side of the two arc-shaped clamps that are far apart from each other, and is fixedly connected to the inside of the placement plate.

[0018] The above technical solution is used to support and limit the sliding of the arc-shaped clamping plate, thereby improving sliding stability.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By driving the slip ring to rotate inside the material cylinder, the threaded suction tube can reciprocate inside the cylinder, sucking up powdery materials from the inner edge of the cylinder. This allows for automatic movement of the suction tube to ensure the material suction efficiency of the suction machine;

[0021] 2. By shaking the material cylinder and utilizing the spring force to move it back and forth on the top of the placement plate, it can not only automatically level the bulges when adding powdered materials, allowing more material to be stored in the cylinder, but also avoid situations where the material is harmful to the human body and requires manual leveling by staff, thus improving safety.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 , Figure 2 , Figure 3 A protective structure for a material suction machine includes a placement plate 1, a material cylinder 2 on top of the placement plate 1, a slip ring 3 slidably connected to the top of the inner cavity of the material cylinder 2, a ring gear 4 fixedly sleeved on the outer surface of the slip ring 3, a threaded suction tube 6 communicating with the inside of the material cylinder 2 being bolted to one side of the inner surface of the slip ring 3, a disc gear 5 rotatably connected to the material cylinder 2 meshing with one side of the surface of the ring gear 4, and a motor 7 being bolted to one side of the surface of the material cylinder 2, with the output end of the motor 7 fixedly connected to the disc gear 5. By driving the slip ring 3 to rotate inside the material cylinder 2, the threaded suction tube 6 can reciprocate inside the material cylinder 2, sucking up the powdery material at the inner edge of the material cylinder 2. This allows for automatic movement of the suction tube to suction material, ensuring the material suction efficiency of the material suction machine.

[0029] refer to Figure 1 , Figure 2 A cover plate 14 is hinged to one side of the top of the material cylinder 2. When not in use, the top of the material cylinder 2 can be covered for protection to prevent dust and impurities from falling into the interior.

[0030] refer to Figure 3A sealing ring 16 is bonded to the outer surface of the slip ring 3 and slides on the inner surface of the material cylinder 2. This improves the sealing between the slip ring 3 and the material cylinder 2, preventing powdery materials from entering the interior.

[0031] refer to Figure 2 An inverted conical block 15 is welded to the bottom of the inner cavity of the material cylinder 2. This allows the powdery material inside the material cylinder 2 to automatically slide down to the bottom edge through the force of the inverted conical block 15, thus facilitating suction by the threaded suction tube 6.

[0032] Brief description of the operation: By placing the material into the inside of the material cylinder 2 and threading the suction pipe of the suction machine into the top of the threaded suction tube 6, a vacuum suction force can be generated at the bottom of the threaded suction tube 6 after the suction machine is turned on. Then, by turning on the motor 7, the disc gear 5 is rotated and meshes with the motor 7, thereby driving the slip ring 3 to rotate inside the material cylinder 2, so that the threaded suction tube 6 can rotate back and forth inside the material cylinder 2. The vacuum suction force is used to suck the powdery material at the edge of the inner cavity of the material cylinder 2 into the suction machine pipe. Since the bottom of the inner cavity of the material cylinder 2 is equipped with an inverted conical block 15, after the powdery material at the edge of the inner cavity is sucked away, the upper layer of powdery material can fall down automatically by gravity, and the powdery material in the middle can also slide down to the edge through the conical surface of the inverted conical block 15, so that all of them can be moved to the bottom of the threaded suction tube 6 for suction.

[0033] Example 2:

[0034] refer to Figure 1 , Figure 2 A protective structure for a material suction machine includes a placement plate 1 with a placement groove 8 inside. A material cylinder 2 is placed inside the placement groove 8. Arc-shaped clamping plates 9, which cooperate with the material cylinder 2, are provided on both sides of the placement groove 8. Springs 10, which are fixedly connected to the placement plate 1, are bolted to the opposite sides of the two arc-shaped clamping plates 9. By shaking the material cylinder 2, the elastic force of the springs 10 causes it to reciprocate on the top of the placement plate 1. This not only automatically flattens any bulges caused by the addition of powdered material, allowing more material to be stored in the container, but also avoids situations where the material is harmful to the human body and requires manual leveling, thus improving safety.

[0035] refer to Figure 1 Each of the four corners of the bottom of the placement plate 1 is equipped with casters 12, and each of the four casters 12 is equipped with a locking device 13 on one side. This facilitates the movement of the placement plate 1, thereby making it easier to convey the powdery material inside the material cylinder 2.

[0036] refer to Figure 2 On the side of the two arc-shaped clamping plates 9 that are far apart from each other, there is also a telescopic rod 11 that is fixedly connected to the inside of the placement plate 1. This is used to support and limit the sliding of the arc-shaped clamping plates 9, thereby improving sliding stability.

[0037] Brief description of usage: By placing the material into the inside of the material cylinder 2, the spring 10 drives the arc-shaped clamping plate 9 to clamp and secure the bottom of the material cylinder 2, thereby reducing the risk of the material cylinder 2 tipping over. Because powdery materials have poor sliding properties, it is very easy for bulges to form at the pouring point when pouring powdery materials into the material cylinder 2. At this time, the material cylinder 2 can be shaken, using the spring 10 to make the material cylinder 2 move back and forth on the top of the placement plate 1, thus leveling the bulge.

[0038] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
