Description

Technical Field

[0001] This invention relates to the field of environmental protection improvement equipment, specifically to a belt conveyor anti-clogging material receiving trough. Background Technology

[0002] With the promotion of green development, environmental protection requirements are becoming increasingly stringent. Many traditional equipment need to undergo environmental improvements. Environmental improvement equipment refers to equipment used to control environmental pollution and improve environmental quality, which can significantly reduce the amount of work caused by environmental incidents. Due to the different pollution sources, the composition, state, and emission volume of pollutants vary considerably. Therefore, it is necessary to conduct specialized process design based on on-site data and adopt the most economical and reasonable process methods and equipment accordingly.

[0003] Among them, the dust pollution caused by the operation of belt conveyors is mainly due to the return material and dust on the belt conveyor falling directly to the ground, causing material accumulation on the ground. This process also causes dust to fly around, and eventually dust settles everywhere. Not only does it require regular manual dust removal, but the dust removal process also becomes troublesome and difficult.

[0004] Currently, the conventional environmental improvement equipment involves installing a collection hopper below the end of the conveyor belt, and then using a scraper to scrape off the returning material from the conveyor belt. This ensures that the scraped material and dust generated during the material drop fall into the collection hopper, preventing material and dust from falling to the ground, and then collecting them all away.

[0005] However, materials and dust can easily accumulate or stick to the side walls of the collection hopper, sometimes even causing blockages inside. Each time this happens, manual intervention is required, wasting manpower and resources.

[0006] In addition, when the belt conveyor transports materials, some fine materials and dust may avoid the scraper and run away with the belt, thus not falling into the collection hopper, resulting in the materials and dust falling directly to the ground. Summary of the Invention

[0007] In view of this, the purpose of this invention is to provide a belt conveyor anti-clogging receiving trough to solve the technical problems in the prior art where materials and dust easily accumulate in the collecting hopper, and fine materials and dust may avoid the scraper and run away with the belt.

[0008] To achieve the above objectives, the present invention provides an anti-clogging receiving trough for a belt conveyor, comprising a support frame and a conveyor belt rotatably connected to the support frame, wherein the anti-clogging receiving trough further comprises:

[0009] A receiving hopper located below the end of the conveyor belt is fixedly connected to a support. The front side plate of the receiving hopper is provided with an inclined plate section, and a sliding plate is slidably connected to the inclined plate section. The bottom of the receiving hopper is provided with a discharge port.

[0010] A drive assembly is rotatably connected inside the receiving hopper. The drive assembly is used to periodically drive the slide plate to slide upward along the inclined plate. The drive assembly is also connected to the output shaft of a drive motor that is fixedly connected to the bracket.

[0011] The scraping mechanism located on the upper part of the front side plate of the receiving hopper is used to scrape off the material and dust adhering to the conveyor belt.

[0012] Furthermore, the output shaft of the drive motor is also fixedly connected to the end drive roller inside the end of the conveyor belt for driving the conveyor belt to rotate.

[0013] Furthermore, a set of guide rollers is provided below the conveyor belt. The height of the upper end of the guide rollers is higher than the height of the lower end of the end drive roller, which is used to make the lower layer of the return conveyor belt from the end drive roller to the guide rollers become an inclined return section. The bracket is rotatably connected to the support.

[0014] Furthermore, the drive assembly includes a movable wheel, a movable column, and a movable rod. The movable column is fixedly connected to the outer arc surface of the movable wheel, and a movable rod groove is provided inside the movable column. The movable rod is slidably connected inside the movable rod groove, and a movable rod spring is provided inside the movable rod groove. The two ends of the movable rod spring are respectively connected to the bottom of the movable rod groove and the bottom end of the movable rod. A stop block that cooperates with the movable rod is provided on the slide plate.

[0015] Furthermore, the movable wheel is rotatably connected to the left and right side walls of the receiving hopper via a rotating shaft, and the rotating shaft is also connected to the output shaft of the drive motor via a transmission belt.

[0016] Furthermore, the receiving hopper is connected to an air supply pipe that is connected to an external air pump. The front side plate of the receiving hopper is also provided with a sliding plate groove. The upper end of the sliding plate is located in the sliding plate groove. The sliding plate groove is also connected to the air supply pipe through a ventilation channel provided in the receiving hopper.

[0017] Furthermore, the top of the slide groove is also provided with a sealing element, which blocks the air passage, and the upper end of the sealing element is slidably connected to the sealing element groove provided in the receiving funnel. The sealing element groove is also provided with a sealing spring, and the two ends of the sealing spring are respectively connected to the top of the sealing element groove and the top of the sealing element.

[0018] Furthermore, the scraping mechanism includes a scraper groove located on the top of the front side plate of the receiving hopper and a scraper slidably connected in the scraper groove. The upper end of the scraper abuts against the lower end surface of the inclined return section. A scraper spring is also provided in the scraper groove, and the two ends of the scraper spring are respectively connected to the bottom of the scraper groove and the bottom end of the scraper.

[0019] The advantages of this invention are: 1. The lower return conveyor belt from the end active roller to the guide roller is changed into an inclined return section, making it easier for materials and dust to fall into the receiving hopper.

[0020] 2. An inclined plate section is provided on the front side plate of the receiving hopper below the inclined return section, and a sliding plate is slidably connected to the inclined plate section to catch the falling materials and dust. The sliding plate slides upward and then falls periodically under the drive of the drive component, so that materials and dust can slide down and prevent accumulation.

[0021] 3. The drive component can periodically drive the slide plate upwards and periodically impact the conveyor belt at the inclined return section, loosening the materials and dust adhering to it and making them easier to fall or be scraped off.

[0022] 4. When the slide plate slides upward to the top of the slide plate groove, it will open the sealing part, allowing air to pass through the slide plate groove and generate air pressure. At this time, the drive component has been separated from the slide plate. Under the combined action of the slide plate's own weight and air pressure, it falls heavily and hits the bottom of the receiving funnel, loosening the material and dust on the slide plate, making it easier to slide down and preventing accumulation.

[0023] 5. The scraper is designed to retract into the scraper trough. Under normal operation, it can scrape off adhering materials and dust. In case of abnormalities, it can also retract into the scraper trough to prevent interference or severe friction with the conveyor belt. Attached Figure Description

[0031] Detailed implementation methods and principles

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0033] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0034] The first aspect of the invention, as Figure 1 , Figure 2 and Figure 3 As shown, an environmentally friendly improved material collection hopper 103 is installed on the existing belt conveyor to collect materials and dust, prevent material accumulation and dust from flying on the ground, control environmental pollution, and improve environmental quality. It also reduces the difficulty of manual dust removal for workers.

[0035] Specifically, a receiving hopper 103 is provided below the end of the conveyor belt 102, and a discharge port 117 is provided at the bottom of the receiving hopper 103. In order to facilitate the material and dust on the conveyor belt 102 to fall more easily into the receiving hopper 103, the lower return section of the conveyor belt 102 from the end drive roller 104 to the guide roller 106 is changed into an inclined return section 107.

[0036] Additionally, the conveyor belt 102 is rotatably connected to the support 101, and the receiving hopper 103 is also rotatably connected to the support 101. The left, right, and rear side plates of the receiving hopper 103 are vertical plates, except for a section of inclined plate 116 on the front side plate of the receiving hopper 103. The inclination angle of the inclined plate 116 is preferably between 45° and 60°. A sliding plate 118 is slidably connected to the inclined plate 116, and the sliding plate 118 completely covers the upper surface of the inclined plate 116. Therefore, the left and right sides of the sliding plate 118 are also slidably connected to the left and right side walls of the receiving hopper 103. The sliding plate 118 is used to catch falling materials and dust.

[0037] Preferably, the slide plate 118 is supported by a smooth stainless steel cold-rolled sheet. The slide plate 118 is only a thin sheet, so it will not be too heavy.

[0038] The slide plate 118 will periodically slide upwards and downwards. Especially when the slide plate 118 slides downwards and finally hits the bottom of the receiving hopper 103, it will loosen the material and dust on the slide plate 118, making it easier to slide down and preventing accumulation.

[0039] The key point is, such as Figure 3 and Figure 4 As shown, the drive assembly for driving the slide plate 118 to periodically slide upward and downward includes a movable wheel 110, a movable column 111, and a movable rod 114. The movable column 111 is fixedly connected to the outer arc surface of the movable wheel 110, and the movable column 111 is also provided with a movable rod groove 112. The movable rod 114 is slidably connected in the movable rod groove 112, and the movable rod groove 112 is also provided with a movable rod spring 113. The two ends of the movable rod spring 113 are respectively connected to the bottom of the movable rod groove 112 and the bottom end of the movable rod 114. The slide plate 118 is provided with a stop block 127 that cooperates with the movable rod 114.

[0040] After the movable wheel 110 rotates once, the movable rod 114 will abut against the stop block 127 once. After the movable rod 114 abuts against the stop block 127, as the movable wheel 110 rotates, the movable rod 114 will drive the slide plate 118 to slide upward through the stop block 127 until the movable rod 114 disengages from the stop block 127.

[0041] The movable wheel 110 has multiple sets of movable columns 111 and movable rods 114, preferably three sets. The three sets of movable columns 111 and movable rods 114 are arranged at equal angles. Therefore, every time the movable wheel 110 rotates once, the three movable rods 114 will abut against the stop block 127 once, and drive the slide plate 118 to slide upward once.

[0042] Through the design of the drive component's position, the movable rod 114 in the drive component can periodically impact the conveyor belt 102 of the inclined return section 107 when it rotates. For example... Figure 4 As shown, the distance between the outermost end of the movable rod 114 and the center of the movable wheel 110 is greater than the minimum distance between the center of the movable wheel 110 and the inclined return portion 107 of the conveyor belt 102. Therefore, for every rotation of the movable wheel 110, each movable rod 114 will strike the inclined return portion 107 of the conveyor belt 102 once, causing the material and dust adhering to it to loosen and become easier to fall or be scraped off.

[0043] Preferably, the movable wheel 110 is rotatably connected to the left and right side walls of the receiving hopper 103 via a rotating shaft 109, and the rotating shaft 109 is also connected to the output shaft of the drive motor 105 via a transmission belt 108. The drive motor 105 is fixedly connected to the bracket 101, and the output shaft of the drive motor 105 is also fixedly connected to the end drive roller 104 inside the end of the conveyor belt 102 for driving the conveyor belt 102 to rotate.

[0044] The connection between the slide plate 118 and the receiving hopper 103 is further aided by other auxiliary structures. By providing a slide plate groove 119 on the front side plate of the receiving hopper 103, the upper end of the slide plate 118 is positioned within the slide plate groove 119. This not only makes the slide plate 118 fit more snugly against the receiving hopper 103 when sliding, but also makes the sliding more stable. An air supply pipe 115 is connected to the receiving hopper 103 and is connected to an external air pump. The slide plate groove 119 is connected to the air supply pipe 115 through a vent 120 located within the receiving hopper 103.

[0045] An external air pump applies atmospheric pressure, which is transmitted to the slide plate groove 119 through the air supply pipe 115 and the air passage 120. This, combined with the weight of the slide plate 118 itself, causes it to fall heavily and hit the bottom of the receiving funnel 103, loosening the material and dust on the slide plate 118 and making it easier to slide down and preventing accumulation. Furthermore, the air blown out through the air between the slide plate groove 119 and the slide plate 118 also makes it easier for dust to fall downwards and finally be collected through the discharge port 117.

[0046] Preferred, such as Figure 5As shown, a sealing element 122 is also provided at the top of the slide groove 119. The sealing element 122 blocks the air passage 120, and the upper end of the sealing element 122 is slidably connected to the sealing element groove 121 provided in the receiving funnel 103. A sealing spring 123 is also provided in the sealing element groove 121. The two ends of the sealing spring 123 are respectively connected to the top of the sealing element groove 121 and the top of the sealing element 122.

[0047] Therefore, when the slide plate 118 slides upward to the top of the slide plate groove 119, it will open the sealing part 122, allowing air to pass through the slide plate groove 119 and generating air pressure. At this time, the drive component has been separated from the slide plate 118. So, under the combined action of its own weight and air pressure, the slide plate 118 will fall heavily and hit the bottom of the receiving funnel 103, loosening the material and dust on the slide plate 118, making it easier to slide down and preventing accumulation.

[0048] On the other hand, such as Figure 3 and Figure 5 As shown, a scraping mechanism is provided at the upper end of the front side plate of the receiving hopper 103 to scrape off the material and dust adhering to the conveyor belt 102. The scraping mechanism includes a scraper groove 125 located at the top of the front side plate of the receiving hopper 103 and a scraper 124 slidably connected in the scraper groove 125. The upper end of the scraper 124 abuts against the lower end surface of the inclined return portion 107. A scraper spring 126 is also provided in the scraper groove 125, with both ends of the scraper spring 126 connected to the bottom of the scraper groove 125 and the bottom end of the scraper 124, respectively.

[0049] Therefore, under normal operation, it can scrape off adhering materials and dust, and in case of abnormalities, it can retract into the scraper groove 125 to prevent interference or severe friction with the conveyor belt 102. Detailed Implementation

[0050] After being conveyed to the end of conveyor belt 102, the material generally falls into the receiving hopper 103 below under its own gravity. In particular, the lower return section of conveyor belt 102 from the end drive roller 104 to the guide roller 106 is converted into an inclined return section 107. The inclination direction is obliquely upward towards the direction of movement of conveyor belt 102, so the material and dust on conveyor belt 102 fall more easily into the receiving hopper 103.

[0051] When materials and dust fall into the receiving hopper 103, a large portion of them will land on the slide plate 118. Since the drive assembly is constantly rotating, after the movable wheel 110 in the drive assembly rotates once, the movable rod 114 will abut against the stop block 127 on the slide plate 118 once. After the movable rod 114 abuts against the stop block 127, as the movable wheel 110 rotates, the movable rod 114 will drive the slide plate 118 to slide upward through the stop block 127 until the movable rod 114 disengages from the stop block 127.

[0052] When the movable rod 114 disengages from the stop block 127, the slide plate 118 slides upward to the top of the slide plate groove 119, which in turn opens the sealing member 122. Atmospheric pressure applied by an external air pump is transmitted to the slide plate groove 119 through the air supply pipe 115 and the vent 120. After the sealing member 122 is opened and the vent 120 is open, air pressure is generated inside the slide plate groove 119, and at this time, the drive component has disengaged from the slide plate 118. Therefore, the slide plate 118 will fall heavily to the bottom of the receiving hopper 103 under the combined action of its own weight and air pressure, loosening the material and dust on the slide plate 118, making it easier to slide down and preventing accumulation. Furthermore, the air blown out through the air between the slide plate groove 119 and the slide plate 118 also makes it easier for dust to fall downwards, and finally collect it through the discharge port 117.

[0053] If any material or dust remains stuck to the conveyor belt 102, there are two additional safety mechanisms. One of these is the drive assembly. Each rotation of the movable wheel 110 causes each movable lever 114 to strike the inclined return section 107 of the conveyor belt 102 once, loosening the stuck material and dust and making it easier for them to fall or be scraped off. Therefore, the drive assembly also periodically impacts the inclined return section 107 of the conveyor belt 102 to further loosen the stuck material and dust, making it easier for them to fall or be scraped off.

[0054] Another component is the scraping mechanism. Under normal operation, the scraping mechanism can scrape off the sticky materials and dust. In case of abnormality, it can retract into the scraper trough 125 to prevent interference or severe friction with the conveyor belt 102.

[0055] Based on the above, this invention transforms the lower return conveyor belt 102 from the end drive roller 104 to the guide roller 106 into an inclined return section 107, making it easier for materials and dust to fall into the receiving hopper 103. A periodically sliding and falling slide plate 118 is provided on the front side plate of the receiving hopper 103 to facilitate the sliding of materials and dust and prevent accumulation. When the slide plate 118 slides upward to the top of the slide plate groove 119, the drive assembly disengages from the slide plate 118. Under the combined action of the slide plate 118's own weight and air pressure, it falls heavily to the bottom of the receiving hopper 103, loosening the materials and dust on the slide plate 118 and making it easier to slide down and prevent accumulation. Additionally, a scraper 124 that can retract into the scraper groove 125 is provided. Under normal operation, it can scrape off adhering materials and dust. In abnormal situations, it can also retract into the scraper groove 125 to prevent interference or severe friction with the conveyor belt 102.
