Description

Technical Field

[0001] The invention belongs to the technical field of transportation equipment, and in particular relates to a scraper-type dust-removing conveyor belt. Background Art

[0002] In the intelligent transportation of agricultural products, conveyor belts, as core equipment, integrate sensors, Internet of Things and other technologies to realize automated material transmission, dynamic weighing and intelligent sorting, improve efficiency, ensure the quality of agricultural products and transportation safety, and assist in the standardized production of smart agriculture.

[0003] Since a large number of agricultural products such as grains and dry goods carry impurities such as dust, in order to prevent dust from floating around and affecting the workshop environment, the conveyor belt needs to have a certain dust removal ability to reduce dust emission. For example, a scraper-type dust-removing conveyor belt disclosed in patent publication number CN106241290B can effectively reduce dust emission during material transportation by combining water sprinkling and scraper scraping. However, water sprinkling is not suitable for most agricultural product transportation (such as grains, dry goods, etc.), and traditional scrapers only scrape off dust and other impurities attached to the conveyor belt. Since the conveyor belt will vibrate during operation, the vibration will cause dust and other impurities attached to the agricultural products to float around, making it difficult to fundamentally reduce dust emission and resulting in poor use effect.

[0016] 4. By setting up the discharge assembly, the material can be discharged evenly when removing dust, so that the material is evenly distributed on the surface of the conveyor belt assembly, which is convenient for subsequent processing of the material and can also prevent uneven distribution of the material from causing eccentric wear of the conveyor belt assembly.

The material discharged by the arc scraper 5 will fall on the side wall of the impact roller 72.

The lower side of the U-shaped hopper 71 is installed There is a discharge component 10, which includes a drive shaft 101 rotatably arranged between two additional plates 4, and a plurality of discharge plates 102 are installed on the shaft wall of the drive shaft 101.

The scraping unit 9 includes a trapezoidal scraper 91 that is horizontally slidably arranged between the two additional plates 4, and the trapezoidal scraper 91 is arranged below the arc-shaped scraper 5.

The timer 114 starts timing after receiving the electrical signal fed back by the pressure sensor 113, and feeds back an electrical signal to the control cabinet 3 after the timing reaches a threshold. When the pressure sensor 113 detects that the pressure exceeds the threshold, it can feed back an electrical signal to the timer 114.

[0024] The operating principle of the present invention is now described as follows: the material is loaded from the feed end of the conveyor belt assembly 2 to the conveyor belt assembly 2 (that is, the side close to the mounting plate 4). When the conveyor belt assembly 2 is working, it can drive the material to move from the feed end box to the discharge end. When the material at the feed end position of the conveyor belt assembly 2 moves to the arc scraper 5 along with the conveyor belt assembly 2, the material will be blocked by the arc scraper 5 due to the small gap between the arc scraper 5 and the upper surface of the conveyor belt assembly 2 (the gap is less than 1 mm), and the control cabinet 3 will control the drive motor 63 to work, and the drive motor 63 will drive the hollow roller 61 to drive each pusher plate 62 to rotate. When the pusher plate 62 rotates to the arc scraper 5, the pusher plate 62 will push the material trapped at the arc scraper 5 to move upward along the arc scraper 5 and finally be discharged through the top position of the arc scraper 5; The material discharged from the top of the arc scraper 5 will fall to the impact roller 72 under the force of the push plate 62 rotating. When the hollow roller 61 rotates, it will drive the impact roller 72 to rotate through the belt drive assembly 73. Under the action of the centrifugal force generated by the rotation of the impact roller 72 and the impact force of the falling material, the dust and other impurities that may be attached to the surface of the material will be separated from the material. The material separated from the impact roller 72 will fall into the U-shaped hopper 71, and when the impact roller 72 rotates, it will The drive shaft 101 is driven to rotate by the chain transmission assembly 104, and the drive shaft 101 drives each discharge plate 102 to rotate, and the material falling into the U-shaped hopper 71 will fall between the two discharge plates 102. When the discharge plates 102 drive the material to rotate to the strip discharge opening 103, the material will fall onto the conveyor belt assembly 2 through the strip discharge opening 103. Due to the limited opening of the strip discharge opening 103, the material falls evenly along the strip discharge opening 103. Before starting to convey the material, the adsorption pipe 82 is connected to the suction pipe of the dust removal system of the external workshop (a fan and a filter device for intercepting dust and other impurities can also be installed separately at the adsorption pipe 82). When the external dust removal system is working, a negative pressure suction force will be generated inside the sealing cover 81 through the adsorption pipe 82, and the sealing cover 81 can generate a negative pressure suction force through the dust suction holes 84 on the side wall of the V-shaped plate 83 through each connecting pipe 85. When the material collides with the impact roller 72, the dust separated by the impact is sucked into the V-shaped plate 83 under the action of the negative pressure suction force of the dust suction holes 84 on the upper side of the V-shaped plate 83. The material falling from the U-shaped hopper 71 will also be sucked into the V-shaped plate 83 due to the different gravity between the material and the dust, and will be affected by the negative pressure suction force of the dust suction holes 84 on the vertical side wall of the V-shaped plate 83. Therefore, the dust that may exist in the material can be fully cleaned out in advance near the feeding end of the conveyor belt assembly 2. At the same time, when the dust on the surface of the conveyor belt assembly 2 moves to the trapezoidal scraper 91, the dust will be intercepted by the trapezoidal scraper 91 because the trapezoidal scraper 91 conflicts with the surface of the conveyor belt assembly 2. As the intercepted dust increases, and the dust suction chamber 93 inside the trapezoidal scraper 91 is connected to the inside of the sealing cover 81, the dust will enter the dust suction chamber 93 along the side wall of the trapezoidal scraper 91 through the dust inlet hole 92, and finally be discharged through the sealing cover 81 and the adsorption pipe 82. Secondly, since the trapezoidal scraper 91 is in conflict with the surface of the conveyor belt assembly 2, the conveyor belt assembly 2 will apply a force opposite to the conveying direction to the trapezoidal scraper 91 when it is working. As the surface of the conveyor belt assembly 2 is worn by the material, the friction force on the surface of the conveyor belt assembly 2 will increase. At this time, when the conveyor belt assembly 2 is working, the friction between it and the trapezoidal scraper 91 will increase. Therefore, the force applied to the trapezoidal scraper 91 will also increase. At this time, the pressure between the trapezoidal scraper 91 and the support plate 111 increases. When the pressure sensor 113 detects that the pressure exceeds the threshold (the pressure exceeds the threshold), the pressure sensor 113 will detect that the pressure exceeds the threshold. The threshold is set based on factors such as the material of the conveyor belt used in the conveyor belt assembly 2). The pressure sensor 113 will feed back an electrical signal to the timer 114, which will immediately start timing. After the timing reaches 10 seconds, the timer 114 will feed back an electrical signal to the control cabinet 3, and the control cabinet 3 will immediately sound an alarm through its own alarm module (because the surface of the conveyor belt assembly 2 may have local wear, by feeding back an electrical signal to the control cabinet 3 after the timer 114 has counted for 10 seconds, false alarms caused by such local wear can be avoided as much as possible); Among them, the transported materials are agricultural products such as corn and rice grains that are not affected by impact.
