In use, the sealed cylinder is hoisted above the material, the end cover is opened, the material is grabbed into the sealed cylinder by the grabbing mechanism, then the end cover is closed, the blowing device blows air into the sealed cylinder while hoisting the sealed cylinder, blowing off the dust or pollutants on the material, the exhaust device sucks these pollutants into the dust bag for storage, when the material is transported to the required position, the blowing device and the exhaust device stop working, the end cover opens, the grabbing mechanism puts the material in the appropriate position, thereby avoiding the pollutants being transferred together with the material, making the material surface clean, avoiding the spread of pollutants.

[0026] Further, the sealed cylinder side wall is provided with an air inlet connected with the blowing device, the air inlet is tangent to the sealed cylinder side wall, so that the wind spirals along the sealed cylinder side wall into the sealed cylinder, so that the sealed cylinder gets no dead angle air flow sweeping.

[0027] The lower end of the sealed cylinder is provided with a downwardly extending support frame 17, the length of the support frame relative to the lower end of the sealed cylinder is greater than the length of the end cover after being opened downward. In order to facilitate the opening of the end cover when the sealed cylinder is supported on the ground or other objects by the support frame, and facilitate the grabbing mechanism to extend from the lower end of the sealed cylinder to grab the material.

[0028] As shown in Figure 3 , 4,5, the grabbing mechanism comprises a first grabbing component, the first grabbing component comprises a first clamping jaw, a second clamping jaw and a traction rope 1 connected with the hoisting device, the first clamping jaw and the second clamping jaw are rotationally connected through a hinge shaft 2 in the middle, the two ends of the first clamping jaw and the second clamping jaw are respectively a first end and a second end, the first end of the first clamping jaw and the second clamping jaw is provided with a first clamping part, the first clamping part is a bending part relative to the inner side of the grabbing mechanism, the second end of the first clamping jaw is connected with the traction rope, the second end of the second clamping jaw is provided with a second guide part, the traction rope slides around the guide part to pull the grabbing mechanism upward. Pulling the traction rope upward, the traction rope makes the second ends of the first clamping jaw and the second clamping jaw close to each other, so that the first clamping parts 9 of the second ends of the first clamping jaw and the second clamping jaw are close to each other to clamp the material, the friction force generated between the material and the first clamping part is balanced with the gravity, so that the object is kept stable, then the traction rope is pulled by using a crane or the like device to hoist the material 12 to the place where it is needed, after hoisting to the place where it is needed to be placed, the traction rope is lowered to make the material be placed in the place where it is needed to be placed, continue to pull the traction rope downward, under the action of gravity, the second ends of the first clamping jaw and the second clamping jaw are away from each other, so that the grabbing mechanism is opened, then the worker can take away the material, and the grabbing mechanism grabs the next material.

[0029] Further, it further comprises a second grabbing component, the second grabbing component comprises a third clamping jaw and a fourth clamping jaw, the third clamping jaw and the fourth clamping jaw are rotationally connected through a hinge shaft in the middle, the two ends of the third clamping jaw and the fourth clamping jaw are respectively a first end and a second end, the first end of the third clamping jaw and the fourth clamping jaw is provided with a second clamping part, the second end of the third clamping jaw and the fourth clamping jaw is respectively provided with a third guide part and a fourth guide part, the traction rope slides around the third guide part and the fourth guide part to pull the grabbing mechanism upward. In this way, when the traction rope is pulled upward, the first clamping jaw and the second clamping jaw, and the third clamping jaw and the fourth clamping jaw can be closed to grab the material, and since the first grabbing component and the second grabbing component are pulled by the same traction rope, when one of the grabbing components cannot continue to close, the other grabbing component can continue to close, and they do not affect each other, so that the two grabbing components grab different parts of the material, thereby being suitable for grabbing complex material shapes.

[0030] Further, the third and fourth clamping jaws are door-shaped frames, which include two parallel outer vertical rods 3, the lower ends of the vertical rods being the second clamping portions 4, the upper ends of the two outer vertical rods being connected by an upper connecting rod 5, the upper connecting rod being the guide portion. The upper connecting rods of the second, third and fourth clamping jaws are provided with guide wheels 6 for guiding the traction rope. The first and second clamping jaws are located between the two parallel outer vertical rods. The first and second clamping jaws are frame structures, which include two parallel inner vertical rods 7, the lower ends of the two inner vertical rods being connected by the first clamping portion, the upper ends of the two inner vertical rods being connected by a lower connecting rod 8, the lower connecting rod of the second clamping jaw being the guide portion, the traction rope being connected to the lower connecting rod of the first clamping jaw. In this way, the first grabbing assembly is located inside the second grabbing assembly, the first grabbing assembly being used to grab the middle part of the object, and the second grabbing assembly being used to grab the two ends of the object.

[0031] The hinge shaft is connected with a bracket 10 located between the first and second clamping jaws, the bracket being provided with a traction rope guide 11 located above the grabbing mechanism. The guide includes two guide wheels, the traction rope sliding through the two guide wheels, thereby providing a guide for the traction rope.

[0032] The end cap includes a first cover plate 18 and a second cover plate 19, which are connected to the lower end of the sealing cylinder by shaft hinges, and are connected to the outer wall of the sealing cylinder by return springs 20. The pulling force of the return springs can cause the first and second cover plates to open to both sides relative to the lower end of the sealing cylinder. The inner sides of the first and second cover plates are connected to the two ends of the hinge shaft by pull ropes 23.

[0033] The traction rope slides through the upper end of the sealing cylinder, the side wall of the sealing cylinder is provided with two opposite upper and lower direction sliding grooves 21, the two ends of the hinge shaft slidingly fit in the sliding grooves, the upper end of the sliding groove has a stopping portion 22 for stopping the hinge shaft. When the hinge shaft is stopped at the stopping portion, the first and second cover plates cover the lower end of the sealing cylinder.

[0034] When the support frame is supported around the material, the traction rope is lowered, so that the grabbing mechanism moves downward, because the hinge shaft moves downward, the pull rope moves downward and loses the pulling force on the end cover, at this time the reset spring is contracted, so that the pull rope, the first cover plate and the second cover plate rotate outward of the port, so that the lower port is opened; then the grabbing mechanism continues to descend to the material, and then the traction rope is pulled upward, so that the grabbing mechanism grabs the material and moves upward, when the hinge shaft is stopped to the stopping part, the first cover plate and the second cover plate cover the lower port of the sealing cylinder, the traction rope continues to move upward, so that the sealing cylinder is pulled upward at the same time through the stopping of the hinge shaft to the stopping part. When the sealing cylinder moves to the position where the material needs to be placed, the traction rope is lowered, so that the grabbing mechanism moves downward, because the hinge shaft moves downward, the pull rope moves downward and loses the pulling force on the end cover, at this time the reset spring is contracted, so that the pull rope, the first cover plate and the second cover plate rotate outward of the port, so that the lower port is opened; then the grabbing mechanism continues to descend and drops the material to the position where it needs to be placed on the ground or the like.

Those skilled in the art can make various modifications or supplements to the described specific embodiments or use similar ways to replace, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.

[0036] Although some terms are used more frequently herein, the possibility of using other terms is not excluded. The use of these terms is only for the convenience of describing and explaining the essence of the present application; it is contrary to the spirit of the present application to interpret them as any kind of additional limitation. The order of actions, steps, etc. in the devices and methods shown in the specification and drawings can be implemented in any order, as long as there is no specific order limitation and the output of the previous processing is not used in the subsequent processing. The use of similar ordinal terms (for example, "first", "then", "second", "again", "then" and the like) for the convenience of description does not mean that it must be implemented in such an order.

[0037] Those skilled in the art will understand that all directional references (e.g., above, below, up, down, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to aid the reader's understanding and do not imply (e.g., a limitation on the scope of the invention as defined by the appended claims) a limitation on the location, orientation, or use of the invention, but are merely for the purpose of facilitating the description of this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation. The directional terms "inside" and "outside" refer to inside or outside relative to the outline of the respective component itself.

[0038] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
