[0008] Furthermore, four connecting shafts are fixedly plugged into the mounting frame, and rollers are movably plugged into the four connecting shafts. The installation positions of the four rollers correspond to the positions of the four drums, and the four steel ropes are movably wound around the circumferential outer surfaces of the four rollers.

[0009] Furthermore, one end of the two mounting shafts are fixedly connected with a first bevel gear, two mounting rods are fixedly installed on one side of the mounting frame, and the two mounting rods are movably connected with a transmission shaft, and two second bevel gears are fixedly connected to the transmission shaft, and the two first bevel gears are respectively meshed and connected with the two second bevel gears, and the two second bevel gears are arranged in opposite directions, and a mounting plate is fixedly installed on the lower side of the mounting frame, and a motor is fixedly installed on the lower side of the mounting plate, and a motor shaft is arranged inside the motor, and the motor shaft movably passes through the mounting plate, and a worm is fixedly installed at one end of the motor shaft, and a worm wheel is fixedly installed at one end of the transmission shaft, and the worm is meshed and connected with the worm wheel, and the motor is electrically connected to an external power supply.

[0010] Furthermore, a plurality of hoop bars are sleeved on the circumferential outer surface of the dust removal pipe, and the plurality of hoop bars are arranged in an array, and cone cylinders are provided inside the dust removal pipe at positions corresponding to the plurality of hoop bars, and eight connecting rivets are fixedly inserted on the plurality of hoop bars, and the eight connecting rivets inserted on the plurality of hoop bars are inserted through the dust removal pipe, and the plurality of hoop bars are fixedly connected to the plurality of cone cylinders through the eight connecting rivets inserted thereon, and four circular rings are fixedly installed on the circumferential outer surfaces of the plurality of hoop bars, and the four steel ropes are movably inserted through the insides of the four circular rings on the plurality of hoop bars.

[0011] Furthermore, the upper side of the shell is fixedly plugged into the feed shell, a blade shaft is movably plugged into the feed shell, five blade plates are fixedly mounted on the circumferential outer surface of the blade shaft, and a small gap exists between one side of the five blade plates and the inner wall of the feed shell.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model provides a dust removal tube, rubber strips and steel wire ropes to solve the problem that the existing telescopic unloading dust removal device has a weak dust removal effect, and the dust removal bag is easily affected by external factors and swings, which affects the dust removal effect. There is a large gap between the bottom tube and the grain pile of the existing telescopic unloading dust removal device. By providing a plurality of rubber strips, since the material of the rubber strips is softer and more closely fits the surface of the grain pile, the gap between the grain falling into the cargo hold of the cargo ship and the bottom tube can be reduced, thereby avoiding a large loss in the suction power of the vacuum cleaner. However, the bottom tube is connected by only two steel wire ropes, which makes it difficult to maintain the balance of the bottom tube and is easily affected by external factors such as wind, which increases the gap between the grain pile and the bottom tube. The device provides four steel wire ropes to connect the bottom tube, which can increase the ability of the dust removal tube and the bottom tube to resist external interference, thereby increasing the practicality of the device.

[0014] 2. The cone cylinders provided can solve the problem that the existing telescopic unloading dust removal device is easily damaged by friction with bulk goods. In the process of grain falling in the dust removal pipe, a small amount of grain will touch the dust removal pipe, causing the inner side of the dust removal pipe to be damaged due to wear. The device has several cone cylinders provided, and in the process of grain falling in the dust removal pipe, a small amount of grain will fall on one of the several cone cylinders, and then continue to fall downward under the guidance of the cone cylinders, which can prevent the grain from contacting the dust removal pipe and avoid damage to the inner side of the dust removal pipe due to wear.

[0015] 3. Through the setting of the feeding shell, blade shaft and blade plate, more external air will enter the existing telescopic unloading dust removal device during feeding, affecting the dust removal effect. The external air of the existing telescopic unloading dust removal device will directly enter the interior of the dust removal pipe through the feeding shell, and the dust collector will suck away this part of the air, thereby weakening the dust removal effect. The device is provided with five blade plates that can rotate around the blade shaft, and there is a small gap between one side of the five blade plates and the inner wall of the feeding shell respectively. The joint action of the above-mentioned settings can play the role of the relevant fan, and then the grain falls between two adjacent blade plates due to gravity. There are five blade plates that are fixedly mounted on the blade shaft and the feeding shell is movably connected to the blade shaft. The weight of the grain piled between the two adjacent blade plates will make the five blade plates unbalanced, and then they will rotate around the blade shaft. Then the horizontal position of the grain is lowered below the position of the blade shaft. The grain will begin to separate from the blade plate due to gravity and continue to fall downward. In this process, only a small amount of air will enter the interior of the dust removal pipe, thereby solving the problem of more external air entering and affecting the dust removal effect.

[0016] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] Several of the rubber strips 5 are in a circular array, the internal space of the sleeve 2 is communicated with the internal space of the dust removal pipe 3, the internal space of the sleeve 2 is communicated with the internal space of the suction cylinder 23, one end of the suction cylinder 23 is connected to the vacuum cleaner through a bellows, and the vacuum cleaner is electrically connected to the control power supply.

[0026] Four connecting shafts 15 are fixedly plugged on the mounting frame 6, and rollers 16 are movably plugged on the four connecting shafts 15. The installation positions of the four rollers 16 correspond to the positions of the four drums 8, and the four steel wire ropes 27 are movably wound around the outer surfaces of the circumferences of the four rollers 16 respectively.

[0027] The four rollers 16 are provided to guide the four steel wires 27 , thereby preventing the four rollers 16 from being too close to the dust removal pipe 3 .

[0028] One end of the two mounting shafts 7 is fixedly plugged with a first bevel gear 9, one side of the mounting frame 6 is fixedly installed with two mounting rods 11, and the two mounting rods 11 are movably plugged with a transmission shaft 12, and two second bevel gears 10 are fixedly plugged on the transmission shaft 12, and the two first bevel gears 9 are respectively meshed and connected with the two second bevel gears 10, and the two second bevel gears 10 are arranged in opposite directions. A mounting plate 13 is fixedly installed on the lower side of the mounting frame 6, and a motor 14 is fixedly installed on the lower side of the mounting plate 13, and a motor shaft is arranged inside the motor 14, and the motor shaft movably passes through the mounting plate 13, and a worm 17 is fixedly plugged at one end of the motor shaft, and a worm wheel 18 is fixedly plugged at one end of the transmission shaft 12, and the worm 17 is meshed and connected with the worm wheel 18, and the motor 14 is electrically connected to an external power supply;

[0029] Since the two second bevel gears 10 are arranged in opposite directions, when the transmission shaft 12 drives the two second bevel gears 10 to rotate, the two first bevel gears 9 can rotate in opposite directions. The two first bevel gears 9 respectively drive the two mounting shafts 7 and the two reels 8 on the two mounting shafts 7 to rotate in opposite directions, and then the four reels 8 can respectively reel in four steel ropes 27.

[0030] The circumferential outer surface of the dust removal pipe 3 is sleeved with a plurality of hoop strips 19, and the plurality of hoop strips 19 are arranged in an array. Conical cylinders 20 are provided inside the dust removal pipe 3 at positions corresponding to the plurality of hoop strips 19, and eight connecting rivets 21 are fixedly inserted on the plurality of hoop strips 19, and the eight connecting rivets 21 inserted on the plurality of hoop strips 19 are inserted through the dust removal pipe 3. The plurality of hoop strips 19 are fixedly connected to the plurality of conical cylinders 20 through the eight connecting rivets 21 inserted thereon, and four circular rings 22 are fixedly installed on the circumferential outer surfaces of the plurality of hoop strips 19, and the four steel ropes 27 are movably inserted through the insides of the four circular rings 22 on the plurality of hoop strips 19.

[0031] The upper side of the shell 1 is fixedly plugged into the feed shell 24 , and a blade shaft 25 is movably plugged into the feed shell 24 . Five blade plates 26 are fixedly installed on the circumferential outer surface of the blade shaft 25 , and one side of the five blade plates 26 has a small gap with the inner wall of the feed shell 24 .

[0032] It should be noted that the utility model is a telescopic unloading dust removal device. Before use, first, one end of the conveyor belt needs to be extended into the interior of the feed shell 24, and then the shell 1 is fixedly connected to the transmission belt through a connecting rod. Then, the user needs to control the control power supply to energize the motor 14. The motor 14 is energized to rotate the motor shaft, and the motor shaft drives the worm 17 to rotate. Since the worm 17 and the worm wheel 18 are meshingly connected, the rotation of the worm 17 can drive the worm wheel 18 to rotate, and the worm wheel 18 can drive the transmission shaft 12 to rotate. Then the transmission shaft 12 drives the two second bevel gears 10 to rotate. Since the two first bevel gears 9 are respectively connected to the two second bevel gears 10 meshing connection, the rotation of the two mounting rods 11 can respectively drive the two first bevel gears 9 to rotate, the two first bevel gears 9 can respectively drive the two mounting shafts 7 to rotate, and then the two mounting shafts 7 respectively drive the two reels 8 thereon to rotate, the four reels 8 can drive the steel wire ropes 27 connected thereon to be respectively wound around the circumferential outer surfaces of the four reels 8, and the four steel wire ropes 27 can drive the bottom pipe 4 to move horizontally upward. When the plurality of hoop strips 19 and the plurality of cones 20 on the dust removal pipe 3 are stacked together, the user can control the control power supply to stop energizing the motor 14, and then move the transmission belt so that the end transmitted to the moving cargo ship is directly above the cargo hold;

[0033] Next, the user needs to control the control power supply to energize the motor 14 in the reverse direction, so that the four drums 8 can rotate in the reverse direction, so that the four steel wire ropes 27 are no longer respectively wound around the outer surfaces of the circumferences of the four drums 8, and then the bottom tube 4 moves horizontally downward under the action of gravity, and when the plurality of rubber strips 5 installed on the bottom tube 4 touch the bottom of the cargo hold of the cargo ship, the user can control the control power supply to stop energizing the motor 14;

[0034] The control power supply is turned on to energize the vacuum cleaner, and then the user can control the grain to be transported to the transmission belt, and then the transmission belt can transport the grain to the inside of the feeding shell 24, and then the grain falls between two adjacent blades 26 due to gravity. There are five blades 26 that are fixedly mounted on the blade shaft 25 and the feeding shell 24 is movably connected to the blade shaft 25. The weight of the grain piled between the two adjacent blades 26 will make the five blades 26 unbalanced, and then rotate around the blade shaft 25. Then the horizontal position of the grain is lowered below the position of the blade shaft 25, and the grain will begin to separate from the blade 26 due to gravity and continue to fall downward. As the conveyor belt continuously transmits the grain, the five blades 26 will continuously rotate, and the grain will continuously enter the dust removal pipe 3 from the inside of the feeding shell 24, and then fall to the bottom of the cargo hold of the cargo ship. At the same time, as the grain falls During the process or when grain falls to the bottom of the cargo hold of the cargo ship, dust will be raised. The suction generated by the operation of the vacuum cleaner will suck the raised dust from the inside of the dust removal pipe 3 into the vacuum cleaner. When a large amount of grain is accumulated, the user can control the control power supply to energize the motor 14, so that the bottom pipe 4 moves horizontally upward to a certain position, and then the user can adjust the horizontal position of the bottom pipe 4 at any time to prevent grain from accumulating inside the dust removal pipe 3. In the process of grain falling in the dust removal pipe 3, a small amount of grain will fall on one of the several cones 20, and then continue to fall downward under the guidance of the cone 20, which can prevent the grain from contacting the dust removal pipe 3 and avoid damage to the inner side of the dust removal pipe 3 due to wear. By setting a plurality of rubber strips 5, the gap between the grain falling into the cargo hold of the cargo ship and the bottom pipe 4 can be reduced, avoiding a large loss of suction of the vacuum cleaner.
