DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 6 The present invention provides a technical solution: a vertical transportation channel for construction waste, including a transportation mechanism and a blocking mechanism.

[0022] The conveying mechanism includes a conveying pipe 1, a feeding pipe 2, a rotating seat 3 and a connecting seat 4 extending in the up-down direction. The rotating seat 3 can be rotatably connected to the bottom of the conveying pipe 1. The connecting seat 4 is fixedly connected to the rotating seat 3 by bolts. The feeding pipe 2 is arranged on one side of the upper end of the conveying pipe 1 for feeding waste. A first buffer mechanism is arranged on the top of the conveying pipe 1, and a detachable second buffer mechanism is arranged inside the connecting seat 4. There are multiple conveying pipes 1, and the top of the conveying pipe 1 can be spliced ​​with the connecting seat 4 at the bottom of another conveying pipe 1.

[0023] The blocking mechanism is arranged on one side of the lower end of the delivery pipe 1 .

[0024] The blocking mechanism includes a shell 5, a blocking plate 6, a rack 7 and a driving gear 27. The shell 5 is fixedly connected to the back of the conveying pipe 1. The blocking plate 6 is rotatably arranged inside the shell 5 through a rotating shaft. The rack 7 is arc-shaped and fixedly connected to the back of the blocking plate 6. The driving gear 27 is arranged on the inner wall of the shell 5 and meshes with the rack 7 to drive the blocking plate 6 to move.

[0025] The blocking plate 6 includes a first limit position which is perpendicular to the extending direction of the delivery pipe 1 and blocks the inside of the delivery pipe 1 , and a second limit position which is flush with the inner wall of the delivery pipe 1 and separates the delivery pipe 1 from the shell 5 .

[0026] A plurality of conveying pipes 1 can be spliced ​​up and down to form a conveying channel extending from the bottom of the building to the top of the building. A feeding pipe 2 is arranged on the side of each conveying pipe 1. Each feeding pipe 2 corresponds to each floor of the building, so that construction waste can be thrown into the feeding pipe 2 and then fall into the bottom of the building along the conveying pipe 1. The rotating seat 3 can rotate around the bottom of the conveying pipe 1 so that the conveying pipe 1 can be staggered to reduce the impact of the waste on the bottom. A forward and reverse motor with a self-locking function is also arranged on the outside of the shell 5. The motor is connected to an external circuit so that the operator can control the forward and reverse rotation and start and stop of the motor externally. The motor is connected to the driving gear 27 through a keyway to drive the driving gear 27 to rotate. When the material is put into the feeding pipe 2, the driving gear 27 drives the rack 7 to move, so that the baffle plate 6 closes the conveying pipe 1. After waiting for this wave of waste material to be fed or the conveying pipe 1 is full, the driving gear 27 drives the rack 7 to reset, so that the baffle plate 6 opens the conveying pipe 1. At this time, the waste remaining in the conveying pipe 1 can fall. At this time, the baffle plate 6 in the lower conveying pipe 1 will be closed, and the waste falling from the upper conveying pipe 1 will fall into the lower conveying pipe 1. Such intermittent falling further reduces the impact caused by the waste falling directly from the top to the bottom. When the waste falls, the baffle plate 6 opens and closes in turn, so that the waste moves step by step from the top to the bottom, reducing the impact on the conveying pipe 1.

[0027] In this embodiment, as a preferred solution, the first buffer mechanism includes a mounting plate 8, a back plate 9 and a baffle 10. The mounting plate 8 is detachably mounted on the top of the conveying pipe 1. The back plate 9 is fixedly connected to the lower surface of the mounting plate 8. The baffle 10 is connected to the back plate 9 through a rotating shaft. A supporting mechanism is provided on the front side of the back plate 9 to support the baffle 10. The supporting mechanism is a compression spring 11. One end of the compression spring 11 is connected to the back plate 9 through a rotating shaft, and the other end of the compression spring 11 is connected to the baffle 10 through a rotating shaft.

[0028] The waste material entering the lower conveying pipe 1 from the upper conveying pipe 1 will impact on the baffle 10, and the compression spring 11 supports the back of the baffle 10. After the waste material collides with the baffle 10, the compression spring 11 will be compressed to reduce the impact of the waste material on the baffle 10 to prevent the waste material from directly impacting the conveying pipe 1 and causing damage to the conveying pipe 1. After impacting the baffle 10, the waste material will fall along the conveying pipe 1 and fall to the bottom of the conveying pipe 1. After passing through multiple conveying pipes 1, it will fall to the bottom of the building. The mounting plate 8 is detachably arranged on the conveying pipe 1. After the device is damaged, the mounting plate 8 can be removed and replaced to reduce the difficulty of maintenance.

[0029] In this embodiment, as a preferred solution, the second buffer mechanism includes a replacement plate 12 and a buffer pad 13. The replacement plate 12 is detachably arranged on one side of the connecting seat 4. The buffer pad 13 is fixedly connected to the upper surface of the replacement plate 12. The surface of the buffer pad 13 is provided with a ridge 14, and the buffer pad 13 is made of rubber.

[0030] The waste material passing through the first buffer mechanism continues to fall along the conveying pipe 1, and after falling on the bottom of the conveying pipe 1, it will collide with the second buffer mechanism at the bottom, thereby reducing the impact on the conveying pipe 1. The replacement plate 12 can be removed from the connecting seat 4, and the entirety can be replaced after the buffer pad 13 is damaged. The ridges 14 on the buffer pad 13 can increase the strength of the buffer pad 13, thereby improving the buffering effect and reducing the falling speed of the waste material.

[0031] In the present embodiment, as a preferred scheme, a feeding channel 15 is opened inside the conveying pipe 1, the feeding pipe 2 is communicated with the inside of the feeding channel 15, a sliding plate 16 that can slide up and down is provided on the front of the feeding pipe 2, and the end of the feeding pipe 2 close to the feeding channel 15 is connected with a movable plate 17 through a torsion spring, and the movable plate 17 is used to close the feeding pipe 2, and feeding ports 18 are opened on both sides of the top of the conveying pipe 1, and a discharge port 19 is provided at the bottom of the connecting seat 4. The feeding port 18 and the discharge port 19 are connected by a positioning mechanism to splice multiple conveying pipes 1 together, and a closing plate 20 is detachably provided on the surface of the feeding port 18 to close one of the feeding ports 18.

[0032] The waste material fed from the feeding pipe 2 will enter the feeding channel 15, be transported to the connecting seat 4 along the feeding channel 15, and then be discharged from the discharge port 19 in the connecting seat 4. The connecting seat 4 is connected to the conveying pipe 1 below, and the waste material discharged from the discharge port 19 will enter the conveying pipe 1 again, and this cycle will repeat until it is transported to the ground. The sliding plate 16 can slide up and down on the front of the feeding pipe 2. When not in use, the feeding pipe 2 can be closed to prevent objects from accidentally falling into the feeding pipe 2. The torsion spring pushes the movable plate 17 to one side of the feeding pipe 2 so that the movable plate 17 fits with one end of the feeding pipe 2 to prevent the waste material falling from above from overflowing from the feeding pipe 2 below. When connecting, the connecting seat 4 is spliced ​​with one side of the conveying pipe 1, and the other side can use a sealing plate to seal the conveying pipe 1 to reduce dust overflow. At the same time, a sealing gasket is provided on the inner wall of the movable plate 17, which can form a closed environment for the feeding channel 15 to further reduce dust overflow.

[0033] In this embodiment, as a preferred solution, the positioning mechanism includes an insert plate 21 and a slot 22 , the insert plate 21 is fixedly connected to one side of the feed port 18 , the slot 22 is opened on one side of the discharge port 19 , and the insert plate 21 is plugged into the slot 22 .

[0034] When the conveying pipe 1 and the connecting seat 4 are spliced, the plug plate 21 on the conveying pipe 1 can be inserted into the slot 22 on one side of the connecting seat 4, so as to fix the conveying pipe 1 and the connecting seat 4 together. After the conveying pipe 1 and the connecting seat 4 are connected together, the waste falling from the upper conveying pipe 1 will enter the connecting seat 4, and then be discharged from the connecting seat 4 into the lower conveying pipe 1. The waste entering the lower conveying pipe 1 will enter the lower connecting seat 4 again, and so on and so forth, falling in sequence until it falls on the ground. The conveying pipes 1 are staggered to reduce the impact of the falling process of the waste.

[0035] In this embodiment, as a preferred solution, a dust removal mechanism may be further provided at the top of the conveying pipe 1 to discharge dust in the conveying pipe 1 .

[0036] The movable plate 17 and the closing plate 20 form a closed structure inside the conveying pipe 1 , and the dust removal mechanism discharges the dust inside the conveying pipe 1 to the outside, thereby reducing the accumulation of dust inside the conveying pipe 1 and extending the service life of the conveying pipe 1 .

[0037] In this embodiment, as a preferred solution, the dust removal mechanism includes an exhaust duct 23, an exhaust fan 24 and a nozzle 25. The exhaust duct 23 is arranged at the top of the conveying pipe 1, and the exhaust fan 24 is arranged on the inner wall of the exhaust duct 23. The exhaust duct 23 is L-shaped, and one end of the exhaust duct 23 is inclined toward the bottom. The nozzle 25 is arranged on the inner wall of the exhaust duct 23 for dust reduction. A water pipe 26 is connected to the top of the conveying pipe 1, and the water pipe 26 is communicated with the nozzle 25.

[0038] The exhaust fan 24 continuously blows the impurities containing dust in the conveying pipe 1 into the exhaust pipe 23 to reduce the accumulation of dust in the conveying pipe 1. At the same time, the water pipe 26 conveys clean water to the nozzle 25. The nozzle 25 sprays the clean water on the dust-containing air to reduce the escape of dust. The exhaust pipe 23 has a downward inclination angle. The clean water sprayed by the nozzle 25 can fall on the exhaust pipe 23 and flow to one side along the inclination angle. A cleaning device is set below to clean the sewage containing dust. The exhaust fan 24 is connected to an external power supply.

[0039] In the present invention, the working steps of the device are as follows: 1. Install the delivery pipe 1 on the outer wall of the building, then connect the connecting seat 4 of the upper delivery pipe 1 with the lower delivery pipe 1, insert the plug plate 21 into the slot 22, so as to ensure that the feed port 18 is connected with the discharge port 19, adjust the orientation angle of the rotating seat 3 according to the needs of the installation position, and install multiple delivery pipes 1 on the outer wall of the building in a staggered manner; 2. A dust removal mechanism is installed on the top of the topmost conveying pipe 1 to process the dust in the conveying pipe 1, and an external water source is connected to the water pipe 26 so that the water pipe 26 can convey clean water to the nozzle 25, which is sprayed out by the nozzle 25 to reduce dust in the air; 3. After installation, it can be used. Start the nozzle 25 and the exhaust fan 24 at the dust removal mechanism to extract the dust-containing air in the conveying pipe 1. During the feeding process, slide the sliding plate 16 upward. At this time, the baffle plate 6 in the conveying pipe 1 is closed. After the feeding is completed or the conveying pipe 1 is full, the sliding plate 16 is reset. After the reset, the motor is started to rotate, driving the driving gear 27 to rotate, so that the baffle plate 6 is reset and the unloading channel 15 of the conveying pipe 1 is opened, so that the waste falls onto the baffle plate 6 in the conveying pipe 1 of the next layer. The baffle plates 6 are opened and closed in turn to make the waste fall from the top; 4. When in use, the barrier plate 6 of a certain layer can be selectively opened according to the type of waste. For example, if the waste is small and light, the barrier plate 6 can be closed once at intervals of multiple layers to increase the falling speed of the waste. If the waste is large and heavy, the barrier plate 6 can be closed once at each layer to reduce the impact of the waste falling at one time on the conveying pipe 1.
