[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a material blocking device for belt conveyors, comprising a conveyor 1, which serves as a carrier for material transport, responsible for transporting materials from one place to another. Two uprights 3 are fixedly connected to the top left and right sides of the conveyor 1, providing vertical support for the entire material blocking device and ensuring the stable installation of subsequent components. A crossbeam 4 is slidably connected between adjacent left and right uprights 3, and between adjacent right uprights 3. The crossbeam 4 can slide between the uprights 3. Threaded holes 5 are provided on the left and right sides of the outer wall of the uprights 3. Threaded holes 6 are provided at the front and rear ends of the crossbeam 4. The threaded holes 6 and 5 work together and are connected by bolts 7, enhancing the stability of the connection between the crossbeam 4 and the uprights 3. The inner walls of the multiple top threaded holes 5 are... Bolts 7 are threaded into threaded holes 5 and 6, respectively, to securely fix the crossbeam 4 to the upright 3 and prevent displacement during operation. The two bolts 7 are threaded into the corresponding threaded holes 6, further ensuring a tight connection between the crossbeam 4 and the upright 3 and guaranteeing the overall stability of the material blocking device. Rotary seats 8 are fixedly connected to the front and rear sides of the top of the left crossbeam 4. The rotating seats 8 provide support and connection points for the rotation of the high baffle plate 10. Fixed ears 9 are rotatably connected to the inner walls of both rotating seats 8. The rear ends of the two fixed ears 9 are fixedly connected to the same high baffle plate 10, which is used for initial material blocking. Spline teeth 11 are provided in the middle of both rotating seats 8. Both fixed ears 9 have a second spline tooth 12 in the middle. The second spline tooth 12 also cooperates with the spline rod 13 and works together with the first spline tooth 11 to enhance the stability of the high baffle plate 10 after angle adjustment. The inner walls of both rotating seats 8 are slidably connected with spline rods 13. The spline rods 13 lock and adjust the angle of the high baffle plate 10 by engaging with the first spline tooth 11 and the second spline tooth 12. The spline rods 13 engage with the corresponding first spline tooth 11 and the second spline tooth 12 respectively. The adjacent ends of the two spline rods 13 are threaded with nuts 14. Tightening or loosening the nuts 14 can control the degree of engagement between the spline rods 13 and the first spline tooth 11 and the second spline tooth 12, making it convenient for operators to adjust the angle of the high baffle plate 10. The bottom of the rear crossbeam 4 A low baffle 15 is fixedly connected, serving as a secondary material blocking structure. It further blocks any material that may overflow after the initial blocking by the high baffle 10, reducing spillage. A cleaning mechanism 2 is installed on the left side of the outer wall of the rear crossbeam 4. This mechanism cleans the low baffle 15, ensuring the normal operation of the high baffle 10's angle adjustment function. A counterweight box 16 is fixedly connected to the bottom left side of the high baffle 10. The counterweight box 16 holds counterweights 17, increasing the weight at the bottom of the high baffle 10 to improve its stability and prevent it from wobbling when blocking materials. The counterweight box 16 contains counterweights 17, whose weight is adjusted according to the actual material conveying conditions, further enhancing the stability of the high baffle 10 and improving its blocking effect.Multiple graduated grooves 18 are provided on the upper and lower sides of the outer walls of the multiple uprights 3, providing a precise reference for adjusting the height of the crossbeam 4 on the uprights 3. This allows operators to accurately adjust the height of the crossbeam 4 according to actual conditions such as material height. The spacing between adjacent graduated grooves 18 is equal, ensuring consistent accuracy in the height adjustment of the crossbeam 4 and facilitating accurate and efficient adjustment operations by operators.

[0032] Specifically, the position adjustment of the crossbeam 4 allows it to slide left and right between the uprights 3 to accommodate belt conveyors of different widths. When the crossbeam 4 slides to the appropriate position, the bolts 7 are screwed into the threaded holes 5 on the left and right sides of the outer wall of the uprights 3 and the threaded holes 6 at the front and rear ends of the crossbeam 4, thus firmly fixing the crossbeam 4 to the uprights 3. When adjusting the angle, first loosen the nut 14 to disengage the spline rod 13 from the spline teeth 11 on the inner wall of the rotating seat 8 and the spline teeth 12 in the middle of the fixing ear 9. At this time, the high baffle plate 10 can be rotated to the appropriate angle to meet the initial material blocking requirements. Then, tighten the nut 14 to make the spline rod 13 re-engage tightly with the spline teeth 11 and 12, fixing the angle of the high baffle plate 10. As the position of the crossbeam 4 on the uprights 3 changes, the height of the high baffle plate 10 also changes. The counterweight 17 is placed inside the counterweight box 16, and its weight can be adjusted according to the actual material conveying conditions. When the material flow rate of the belt conveyor is large and the impact force is strong, the number of counterweights 17 can be increased or heavier counterweights 17 can be replaced to give the bottom of the high baffle plate 10 greater gravity, enhance its stability, and ensure that it will not shake or shift due to the impact of the material when blocking the material, effectively guaranteeing the initial material blocking effect.

[0033] Reference Figure 1 , Figure 4 and Figure 5The cleaning mechanism 2 includes a threaded rod 201. The front and rear ends of the threaded rod 201 are rotatably connected to the front and rear sides of the rear crossbeam 4, respectively. The rotation of the threaded rod 201 provides a supporting foundation, enabling it to rotate stably. A groove 202 is provided on the left side of the outer wall of the rear crossbeam 4, providing a sliding track for the slider 203. The slider 203 is slidably connected to the inner wall of the groove 202. The slider 203 is threadedly connected to the threaded rod 201. Utilizing the principle of threaded transmission, the rotation of the threaded rod 201 is converted into linear motion of the slider 203 along the groove 202. A cleaning rod 204 is fixedly connected to the left side of the outer wall of the slider 203. As the slider 203 moves, it drives the cleaning rod 204 to move synchronously. A scraper is fixedly connected to the rear side of the outer wall of the cleaning rod 204. The cleaning rod 204 and scraper 205 are all attached to the low baffle 15. During the movement, the scraper 205 can scrape off the material residue and other debris attached to the surface of the low baffle 15, keep the low baffle 15 clean, and ensure its secondary material blocking effect. The front end of the threaded rod 201 passes through the rear crossbeam 4 and is fixedly connected to the rotating disk 24. The rotating disk 24 provides a component that facilitates the application of force for the rotation operation of the threaded rod 201. The front side of the outer wall of the rotating disk 24 is rotatably connected to the anti-slip handle 25. The anti-slip handle 25 increases the friction between the operator's hand and the rotating disk 24, making it convenient for the operator to drive the rotating disk 24 by rotating the anti-slip handle 25, thereby driving the threaded rod 201 to rotate, and realizing the manual operation of the cleaning mechanism 2.

[0034] Specifically, the threaded rod 201 rotates, and its front and rear ends are stably rotatably connected to the front and rear sides inside the rear crossbeam 4, providing support for its rotation. Since the slider 203 is threadedly connected to the threaded rod 201 and can slide within the groove 202 opened on the left side of the outer wall of the crossbeam 4, according to the principle of threaded transmission, the rotation of the threaded rod 201 is converted into the linear movement of the slider 203 along the groove 202. The cleaning rod 204 fixed on the left side of the outer wall of the slider 203 moves synchronously, and the scraper 205 fixed on the rear side of the outer wall of the cleaning rod 204 also moves together. The scraper 205 is always in close contact with the low baffle 15. As the cleaning rod 204 moves, the scraper 205 effectively removes material residues, dust, and other debris adhering to the surface of the low baffle 15. In this way, the cleaning mechanism 2 continuously cleans the low baffle 15, ensuring that the low baffle 15 maintains a good secondary material blocking effect during long-term use, reducing problems such as insufficient material blocking and material spillage caused by material residue, and ensuring the high efficiency and stability of the belt conveyor. During cleaning, the operator holds the anti-slip handle 25 and applies force. The anti-slip handle 25 is rotatably connected to the rotating disk 24, causing the rotating disk 24 and the threaded rod 201 to rotate simultaneously.

[0035] Reference Figure 1 , Figure 3 and Figure 5An information board 19 is installed on the front side of the outer wall of the conveyor 1. Screws 20 are threaded at the four corners of the outer wall of the information board 19. The rear ends of the screws 20 are threaded to the conveyor 1. The information board 19 is fixed to the front side of the outer wall of the conveyor 1 by the screws 20 threaded at the four corners, and records relevant information of the conveyor 1 for easy viewing by operators. The front ends of the screws 20 are provided with cross grooves 21. The surfaces of the screws 20 are smoothed. The cross grooves 21 facilitate installation and removal with a Phillips screwdriver. The smooth surface treatment reduces the risk of dust adhesion and corrosion. An installation rod 22 is fixedly connected to the left side of the top front end of the conveyor 1. A height detector 23 is fixedly connected to the rear side of the outer wall of the installation rod 22. The height detector 23 is installed on the rear side of the outer wall of the installation rod 22 and is used to detect the height of the material on the conveyor belt in real time. Once the material height is abnormal, a signal can be sent in time so that the staff can adjust the conveying volume or check the equipment to ensure the stable operation of the conveyor 1.

[0036] Specifically, the information board 19 is fixed to the front side of the outer wall of the conveyor 1 by screws 20 connected by threads at the four corners, recording relevant information of the conveyor 1 for easy viewing by operators. The cross groove 21 facilitates installation and disassembly using a Phillips screwdriver, and the smooth surface treatment reduces the risk of dust adhesion and corrosion. The height detector 23 is installed on the rear side of the outer wall of the mounting rod 22 to detect the height of the material on the conveyor belt in real time. Once the material height is abnormal, a signal can be sent in time so that the staff can adjust the conveying volume or check the equipment to ensure the stable operation of the conveyor 1.

[0037] Working principle: The crossbeam 4 can slide flexibly left and right between the uprights 3. The operator moves the crossbeam 4 to a suitable position according to the actual width of the conveyor belt, then picks up the bolt 7 and screws it into the threaded holes 5 on the left and right sides of the outer wall of the upright 3 in sequence, and then screws it tightly into the threaded holes 6 at the front and rear ends of the crossbeam 4. In this way, the crossbeam 4 is firmly fixed on the upright 3, providing stable support for the installation and operation of subsequent components. When it is necessary to adjust the angle of the high baffle 10 for better initial material blocking, the operator first uses a tool to loosen the nut 14. After the nut 14 is loosened, the spline rod 13 and the inner wall of the rotating seat 8 are... The spline tooth 11 and the spline tooth 12 in the middle of the fixed ear 9 are no longer tightly engaged. The high baffle plate 10 is now rotatable. The operator rotates the high baffle plate 10 to a suitable angle to meet the initial material blocking requirements according to the material conveying situation. After determining the angle, tighten the nut 14 again. The spline rod 13 is tightly engaged with the spline tooth 11 and the spline tooth 12 again, thereby fixing the angle of the high baffle plate 10. In addition, as the position of the crossbeam 4 on the upright 3 changes, the overall height of the high baffle plate 10 will also be adjusted accordingly, further meeting the diverse needs of the material blocking device under different conveying conditions.

[0038] Furthermore, when the low baffle 15 needs to be cleaned, the external power causes the threaded rod 201 to rotate. Since the slider 203 is threadedly connected to the threaded rod 201, it can slide in the groove 202 on the left side of the outer wall of the crossbeam 4. According to the principle of threaded transmission, the rotation of the threaded rod 201 causes the slider 203 to move linearly along the groove 202. When the slider 203 moves, the cleaning rod 204 fixed on the left side of its outer wall moves synchronously. The scraper 205 fixed on the rear side of the outer wall of the cleaning rod 204 also moves forward together. The scraper 205 always sticks to the low baffle 15. During the movement, it effectively scrapes off the material residue, dust and other debris attached to the surface of the low baffle 15.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
