Description

Technical Field

[0001] The utility model relates to the field of belt conveyor cleaning, in particular to a belt conveyor bottom cleaning machine which is convenient for a scraper to pass through obstacles. Background Art

[0002] The bottom cleaner of the belt conveyor is a device specially used to clean the residual materials or debris at the bottom of the belt conveyor. During the operation of the belt conveyor, materials may fall or remain at the bottom of the belt conveyor during transportation. These residues will not only affect the normal operation of the belt conveyor, but also may pollute the production environment. Therefore, the bottom cleaner of the belt conveyor can clean these residues in time and keep the belt conveyor clean and running efficiently.

[0003] The current belt conveyor bottom sweeper has a scraper on the chain with a certain height and the support plate at the bottom of the chain is integrated, so the chain above the support plate cannot sink. When encountering a belt conveyor with a low installation height, the scraper will touch the components at the bottom of the belt conveyor to cause interference, affecting the normal use of the belt conveyor bottom sweeper.

[0004] During the cleaning process of the anti-chain-off belt sweeper of the above patent, the moving trajectory of the scraper is fixed, but the protruding transmission structure positions of different types of belt conveyors are different. The belt sweeper cannot adapt to the positions of different transmission structures and make adjustments, resulting in poor adaptability of the belt sweeper. Utility Model Content

[0005] The utility model aims to provide a belt conveyor bottom sweeper which facilitates the scraper to pass through obstacles. The traditional one-piece chain is arranged into sections, and a gap is provided between the two chains to form a sinking groove. When the chain passes through the sinking groove, the chain sinks in the sinking groove due to the lack of support from the first support plate and the second support plate. The chain is pressed down by a pressing mechanism to reduce its upward floating, thereby avoiding interference between the scraper and the obstacles at the bottom of the belt conveyor, and solving the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A belt conveyor bottom sweeper that facilitates a scraper to pass through obstacles, comprising a frame and sprockets arranged at the front and rear ends of the frame, chains being sleeved on the sprockets at both ends, a first support plate and a second support plate being arranged on both sides of the frame, a sinking groove for the chain to sink between the first support plate and the second support plate on one side of the frame, and a chain pressing mechanism being installed at the top of the frame.

[0008] Furthermore, the ends of the first supporting plate and the second supporting plate on one side that are close to each other are both configured to have an arc and a slope structure for facilitating the passage of the chain.

[0009] Furthermore, the chain pressing mechanism includes a bearing seat, a rotating shaft and a lower pressure wheel. The bearing seat is installed on the upper end of the frame by bolts, and the two sides of the rotating shaft are installed inside the bearing seat by bearings. The rotating shaft is provided with two lower pressure wheels for pressing down the chain.

[0010] Furthermore, a groove for embedding the chain is arranged around the middle of the lower pressure wheel.

[0011] Furthermore, the installation position of the chain pressing mechanism is adjusted through a mounting hole opened on the frame.

[0012] Furthermore, the chain pressing mechanism is installed above the sink.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model arranges the chain support plate in a split type, a sink groove is formed between the first support plate and the second support plate on one side, and a chain pressing mechanism is arranged above the sink groove, and inclined structures are arranged on the first support plate and the second support plate to assist the movement of the chain. After the chain and the scraper move to the sink groove, they sink, the chain passes under the lower pressure wheel, and the scraper passes under the rotating shaft. Since the chain pressing mechanism is close to the obstacle at the bottom of the belt conveyor and the sink groove has a certain length, the length can cover the obstacle at the bottom of the belt conveyor, thus ensuring that the scraper can pass through the obstacle at the bottom of the belt conveyor smoothly, the scraper will not interfere with the obstacle at the bottom of the belt conveyor, thereby not affecting normal cleaning. The utility model can adapt to various obstacles at the bottom of the belt conveyor, thereby improving the scope of application. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In order to solve the problem that the scraper of the existing anti-chain-off belt cleaning machine is easy to get off during the cleaning process, this embodiment provides the following technical solutions:

[0020] A belt conveyor bottom cleaning machine that facilitates a scraper to pass through obstacles comprises a frame 1 and sprocket wheels 2 arranged at the front and rear ends of the frame 1. Figure 1 As shown, chains 3 are sleeved on the sprockets 2 at both ends, and the sprockets 2 at the front and rear ends are a driving wheel and a driven wheel, respectively. The frame 1 has two chains 3, which are driven by the sprockets to move the two chains 3, and are used to pull the scraper 11 to scrape the material at the bottom of the belt conveyor, thereby cleaning the bottom of the belt.

[0021] In this embodiment, if Figure 2 As shown, a first support plate 4 and a second support plate 5 are provided on both sides of the interior of the frame 1, and a sinking groove 6 for sinking the chain 3 is provided between the first support plate 4 and the second support plate 5 on one side of the frame 1. The utility model arranges the first support plate 4 and the second support plate 5 into two independent structures (the traditional first support plate 4 and the second support plate 5 are integrated, and the chain cannot sink). A chain pressing mechanism is installed on the top of the frame 1. When the chain 3 passes through the sinking groove 6 area, it sinks together with the scraper 11 due to its own gravity. At this time, the upper chain pressing mechanism limits the chain 3 and presses down the passing chain 3 to prevent the chain 3 from floating up due to shaking during the movement. The sinking chain 3 and the scraper can smoothly pass through the obstacles at the bottom of the belt conveyor.

[0022] The chain pressing mechanism includes a bearing seat 7, a rotating shaft 8 and a lower pressure wheel 9. The bearing seat 7 is installed on the upper end of the frame 1 by bolts. The frame 1 is provided with a plurality of mounting holes 10. The mounting position of the chain pressing mechanism is adjusted by the mounting holes 10 provided on the frame 1. It is used to adjust the mounting position of the bearing seat 7 according to the position of obstacles at the bottom of the belt conveyor. It is more flexible to use. The two sides of the rotating shaft 8 are installed inside the bearing seat 7 through bearings. Two lower pressure wheels 9 for pressing down the chain 3 are provided on the rotating shaft 8. A groove for embedding the chain 3 is provided around the middle of the lower pressure wheel 9. The chain 3 slides along the groove to keep its walking path from deviating to both sides.

[0023] In this embodiment, the ends of the first support plate 4 and the second support plate 5 on one side that are close to each other are both configured to have an arc and an inclined surface structure for facilitating the passage of the chain 3. The inclined surface structure can transition the moving chain 3 to avoid the ends of the first support plate 4 and the second support plate 5 from causing large scratches on the chain 3.

[0024] The chain pressing mechanism is installed above the sinking trough 6 to ensure that the chain 3 can sink here, and the chain pressing mechanism is combined to press the chain 3 down to ensure that the scraper 11 can smoothly pass through the obstacles at the bottom of the belt conveyor.

[0025] Working principle: Place the sink 6 in the utility model below the obstacle at the bottom of the belt conveyor, adjust the installation position of the bearing seat 7 through the bolts and the mounting holes 10, so that the chain pressing mechanism is located in front of the obstacle at the bottom of the belt conveyor, and the chain pressing mechanism is close to but not in contact with the obstacle at the bottom of the belt conveyor. After the bearing seat 7 is fixed and installed, the chain 3 pulls the scraper 11 forward under the drive of the sprocket 2, and the sprocket 2 enters the sink 6 through the inclined structure at the end of the first support plate 4. The chain 3 and the scraper 11 move to the sink 6 and then sink. The chain 3 passes from under the lower pressure wheel 9, and the scraper 11 passes from under the rotating shaft 8, and then passes from under the obstacle at the bottom of the belt conveyor, and then slides upward by the inclined structure of the second support plate 5 to enter horizontal movement, thereby achieving smooth passing through the obstacle at the bottom of the belt conveyor.
