Description

Technical Field

[0001] The invention relates to the technical field of scraper conveyors, in particular to an electrically heated scraper conveyor and a control method thereof. Background Art

[0002] Scraper conveyor is a material conveying device, which is used in coal mines, mining, food, grain and oil industries. Scraper conveyor is also suitable for metallurgy, building materials, electricity, chemical industry and other industries and departments. It has a wide range of uses. There are different types of scraper conveyors according to production needs. For example, when transporting materials in a low temperature environment, in order to prevent the materials from freezing together and affecting the normal operation of the equipment, the scraper conveyor needs to have a heating function to adapt to the material transportation operation in the severe cold environment. Therefore, the electrically heated scraper conveyor came into being; In a scraper conveyor disclosed in publication number CN116477285A, a first adjustment part is used to adjust the height of one end of the conveying device, and the other end of the conveying device is connected to a base, so that there is a height difference between the connecting end of the conveying device and the first adjustment part relative to the other end of the conveying device in the height direction, and the overall inclination angle of the conveying device can be conveniently adjusted to meet different conveying requirements; at the same time, a retractable second adjustment part is used to make the baffle for carrying sludge on the conveying device have an inclination angle, and the angle of the baffle can be flexibly adjusted according to actual conditions, thereby improving the operability of the baffle, and by setting a baffle with an adjustable inclination angle, the single pushing amount of the sludge is regulated, and the stability of sludge transmission is guaranteed to a certain extent, thereby improving the transmission efficiency; However, the above scheme still has the following problems during use: during the use of the device, the material is transported by the operation of the scraper, and the overall height of the equipment is adjusted to meet the requirements, and the use angle of each scraper is adjusted. This process is cumbersome and time-consuming, which affects the work progress. It is not convenient to adaptively adjust the scraper angle according to the actual situation of the material. For materials with high viscosity, the direct transportation through the operation of the scraper has large resistance and residues are easily generated on the inner wall of the conveyor. As the use time increases, the material residue becomes more serious, which affects the use of the scraper conveyor, and it is necessary to improve the quality and efficiency of material transportation.

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.

The embodiment of the present invention can solve the above problem, and the specific implementation method is as follows: The guide deflection assembly 7 is arranged on the inner wall of the initial section of the conveyor body 1, and the guide deflection assembly 7 smoothly conveys the material with high viscosity by changing the use angle of the scraper body 3; Before conveying the material, the use angle of the scraper body 3 is adjusted according to the actual situation of the material, and the angle between the scraper body 3 and the conveying trough is adjusted according to the conveying requirements of different materials. For materials with high viscosity, the angle of the scraper body 3 can be reduced to increase the contact area between the scraper body 3 and the material and improve the conveying efficiency; for materials with good fluidity, the angle of the scraper body 3 can be increased to speed up the conveying speed of the material.

[0023] As an embodiment of the present invention, the guide deflection assembly 7 includes a top plate 701 fixed to the inside of the initial section of the conveyor body 1, and a guide plate 702 is hingedly connected to the bottom of the left side of the top plate 701, and the guide plate 702 is located before the material feeding port, and an electric push rod 703 is hingedly provided at the bottom of the left side of the top plate 701, and the bottom of the electric push rod 703 is hingedly connected to the top of the guide plate 702; During operation, after the electric push rod 703 is started, it will push the guide plate 702 to rotate, thereby increasing the angle between the guide plate 702 and the top plate 701. After the guide plate 702 rotates, the scraper body 3 will rotate when passing through the guide plate 702, thereby changing the use angle of the scraper body 3 and improving the conveying efficiency.

[0024] As an embodiment of the present invention, a first oil tank 704 is fixed to the middle of the bottom surface of the top plate 701, and the bottom of the first oil tank 704 is slidably connected to the first piston plate 705 through a spring, and the bottom of the first piston plate 705 is fixed to the top of the bottom plate 706, and the bottom plate 706 is set to a horizontal state, and the bottom plate 706 is flush with the bottom of the guide plate 702, and the bottom of the guide plate 702 is fixed to the second piston plate 707, and the bottom of the second piston plate 707 is slidably connected to the second oil tank 708 through a spring, and the second oil tank 708 is fixed to the top of the guide plate 702, and the second oil tank 708 is connected to the first oil tank 704 through a connecting pipe; During operation, the guide plate 702 rotates and drives the second piston plate 707 to slide in the second oil tank 708, thereby squeezing the oil into the first oil tank 704. The first piston plate 705 is pushed out, thereby causing the bottom plate 706 to move downward. After the bottom plate 706 moves downward, it is flush with the bottom of the guide plate 702. After the scraper body 3 rotates an angle, the top moves along the bottom plate 706, thereby maintaining the angle after rotation.

[0025] As an embodiment of the present invention, a first pull rope 709 is fixed to the bottom of the left side of the top plate 701, and the bottom of the first pull rope 709 is connected with a first screw rod 710, and the first screw rod 710 is rotatably connected to the inside of the guide plate 702 through a torsion spring, and the outer side of the first screw rod 710 is threadedly connected to an extension plate 711, and the extension plate 711 is slidably connected to the bottom of the guide plate 702; During operation, when the guide plate 702 changes its angle, it will pull the first pull rope 709, and the first pull rope 709 will drive the first screw 710 to rotate. After the first screw 710 rotates, the extension plate 711 will extend, thereby extending the length of the guide plate 702, so that the bottom of the guide plate 702 is always flush with the bottom plate 706.

[0026] During operation, when the scraper body 3 is conveyed at an angle, in order to ensure that it can maintain contact with the conveying groove of the device, it is necessary to timely extend the length of the scraper body 3 after the angle is changed. The specific implementation method is as follows: The length adjustment component 8 is arranged inside the scraper body 3 and outside the mounting frame 4, and the length adjustment component 8 extends the use length after the scraper body 3 rotates, so that the scraper body 3 can maintain a state of contact with the inner bottom of the conveyor body 1. After the rotation angle, the scraper body 3 will not contact the conveying trough. In order to ensure the conveying effect of the material, the use length of the scraper body 3 needs to be adjusted, and the extension plate 5 is extended so that the shovel plate 6 contacts the conveying trough, thereby improving the material conveying work; As an embodiment of the present invention, the length adjustment assembly 8 includes a toothed plate 801 fixed to the outer arc of the mounting frame 4, and the end of the toothed plate 801 penetrates and slides on the scraper body 3, and the scraper body 3 is internally rotatably connected with a gear 802 meshing with the toothed plate 801, and the shaft of the gear 802 is connected to the top of the second screw 803 in the middle of the inner side of the scraper body 3 through a bevel gear connector, and the bottom outer side of the second screw 803 is threadedly connected with an extension plate 5; When working, the scraper body 3 rotates, causing the tooth plate 801 to pass through the scraper body 3 and then mesh with the gear 802. After the gear 802 rotates, it drives the second screw 803 to rotate through the bevel gear connector. The second screw 803 drives the extension plate 5 to extend. The extension plate 5 drives the shovel plate 6 to maintain contact with the conveying trough, thereby maintaining the state of pushing the material. During operation, when conveying materials, the direct pushing method makes the material conveying incomplete, and more sticky materials remain in the conveying trough, thereby reducing the conveying quality. The embodiments of the present invention can solve the above problems, and the specific implementation methods are as follows: The movable scraper assembly 9 is arranged at the bottom of the guide deflection assembly 7 and inside the scraper body 3 and the extension plate 5, and the movable scraper assembly 9 reduces the resistance and material residue when the scraper body 3 conveys materials; When the scraper body 3 is conveying, the shovel plate 6 moves forward and backward synchronously, which reduces the residue between the sticky material and the conveying trough and also reduces the resistance of material conveying.

[0027] As an embodiment of the present invention, the movable scraper assembly 9 includes a second pull rope 901 fixed at an equal interval to the bottom of the top plate 701, and the bottom of the second pull rope 901 is connected to the shaft of the electromagnet 902, and the electromagnet 902 is rotatably connected to the bottom of the bottom plate 706 at an equal interval through a torsion spring, and the electromagnet 902 forms a rotating structure through the second pull rope 901 and the torsion spring, the bottom of the electromagnet 902 is intermittently close to the iron block 903, and a "U"-shaped slide plate 904 is fixed to the bottom of the iron block 903, and the slide plate 904 is slidably connected to the bottom of the oil chamber 905, and the oil chamber 905 is opened on the top inner side of the scraper body 3, and a sealing plate 906 is integrally installed on the outer middle part of the slide plate 904, and the area of ​​the sealing plate 906 covers the opening range between the slide plate 904 and the scraper body 3; During operation, after the bottom plate 706 moves downward, it will pull the second pull rope 901, and the second pull rope 901 will drive the electromagnet 902 to rotate. After the electromagnet 902 is energized, when the scraper body 3 passes under the electromagnet 902, the iron block 903 will be adsorbed and moved upward by the electromagnet 902, and the iron block 903 will drive the slide plate 904 to move upward in the oil chamber 905 synchronously, thereby squeezing out the oil in the oil chamber 905, and during the sliding of the slide plate 904, the sealing plate 906 will close the movable opening on the scraper body 3 to prevent materials from entering.

[0028] As an embodiment of the present invention, the top of the oil chamber 905 is connected to the third oil tank 907 through a connecting pipe, and the third oil tank 907 is installed on the inner wall of the sliding part of the shovel plate 6 at the bottom of the extension plate 5, and the end of the third oil tank 907 slides with a third piston plate 908, and the end of the third piston plate 908 abuts against the right side of the slider 909, and the slider 909 is installed in the middle of the top surface of the shovel plate 6, and a spring is installed between the slider 909 and the bottom of the extension plate 5; During operation, after the oil in the oil chamber 905 is transported to the third oil tank 907, the third piston plate 908 on the third oil tank 907 will extend, thereby pushing the slider 909 to drive the shovel plate 6 to slide, thereby compressing the spring. When the iron block 903 and the electromagnet 902 are misaligned, the slide plate 904 will move down and reset, and the spring will push the shovel plate 6 to reset. In this way, the shovel plate 6 can move back and forth, which can not only better scrape and push the sticky material, but also reduce material residue and improve the conveying quality.

[0029] A control method for an electrically heated scraper conveyor, the control method comprising the following steps: S1. Based on the first control information sent by the controller, the first control information is used to drive the electric push rod 703, and the electric push rod 703 drives the guide plate 702 to rotate, thereby adjusting the overall inclination angle of the scraper body 3 according to the viscosity of the material, so as to better transport the material; S2, the second control information sent by the controller starts the motor, and the motor drives the running link 2 to run through the transmission roller, drives the scraper body 3 to move, and then transports the material; S3, the controller sends a third control information to make the heating plate 10 work, so as to prevent the material from freezing and accumulating due to low temperature during transportation, which may affect the transportation work; S4, the controller sends out the fourth control information, so that the electromagnet 902 is in the power-on state. When the scraper body 3 passes by, the shovel plate 6 will slide back and forth at the bottom of the extension plate 5, reducing the resistance between the material and the bottom wall of the conveyor during transportation, and also reducing the residual material at the bottom inside the conveyor.

[0030] Working principle: After the material is placed in the conveyor body 1 from the delivery port, the running link 2 drives the mounting frame 4 and the scraper body 3 to operate and transport the material upward. The heating plate 10 can increase the temperature of the conveying trough to maintain the fluidity of the viscous material. The use angle of the scraper body 3 is adjusted according to the actual situation of the material. The angle between the scraper body 3 and the conveying trough is adjusted according to the conveying requirements of different materials. For materials with greater viscosity, the angle of the scraper body 3 can be reduced to increase the contact area between the scraper body 3 and the material, thereby improving the conveying efficiency; for materials with better fluidity, the angle of the scraper body 3 can be increased to speed up the conveying speed of the material. After the electric push rod 703 is started, it will push the guide plate 702 to rotate, thereby increasing the angle between the guide plate 702 and the top plate 701. After the guide plate 702 rotates, the scraper body 3 When passing through the guide plate 702, it will rotate, thereby changing the use angle of the scraper body 3. After the guide plate 702 rotates, it drives the second piston plate 707 to slide in the second oil tank 708, and then squeezes the oil into the first oil tank 704. The first piston plate 705 is pushed out, thereby causing the bottom plate 706 to move downward. After the bottom plate 706 moves downward, it is flush with the bottom of the guide plate 702. When the guide plate 702 changes its angle, it will pull the first pull rope 709, and the first pull rope 709 will drive the first screw rod 710 to rotate. After the first screw rod 710 rotates, the extension plate 711 will extend, thereby extending the length of the guide plate 702, so that the bottom of the guide plate 702 is always flush with the bottom plate 706. After the scraper body 3 rotates, the top moves along the bottom plate 706, thereby maintaining the angle after rotation. When the scraper body 3 rotates, the tooth plate 801 passes through the scraper body 3 and then meshes with the gear 802. When the gear 802 rotates, it drives the second screw 803 to rotate through the bevel gear connector. The second screw 803 drives the extension plate 5 to extend. The extension plate 5 drives the shovel plate 6 to keep in contact with the conveying trough, thereby maintaining the state of pushing the material. After the bottom plate 706 moves downward, it will pull the second pull rope 901, and the second pull rope 901 will drive the electromagnet 902 to rotate. After the electromagnet 902 is energized, when the scraper body 3 passes under the electromagnet 902, the iron block 903 will be attracted by the electromagnet 902 and move upward, and the iron block 903 will drive the slide plate 904 to move upward in the oil chamber 905 synchronously, thereby squeezing out the oil in the oil chamber 905. After the oil in the oil chamber 905 is transported to the third oil tank 907, the third piston plate 908 on the third oil tank 907 will extend out, thereby pushing the slider 909 to drive the shovel plate 6 to slide, thereby compressing the spring. When the iron block 903 and the electromagnet 902 are misaligned, the slide plate 904 will move downward and reset, and the spring will push the shovel plate 6 to reset, so that the shovel plate 6 can move back and forth back and forth, which can not only better scrape and push the sticky material, but also reduce material residue and improve the conveying quality.
