[0030] 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. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 3 As shown, the embodiment of the utility model provides a belt conveyor, which includes a conveyor belt 10, a mounting seat 20 and a buffer device 30. The conveyor belt 10 is arranged on the mounting seat 20, and the buffer device 30 is arranged on the mounting seat 20. The buffer device 30 has a material inlet 301 and a material outlet that are arranged relatively. The material inlet 301 is located above the material outlet, and the material outlet is arranged corresponding to the conveyor belt 10. A screening component and a buffer component are arranged between the material inlet 301 and the material outlet. The material passing through the material inlet 301 can be screened by the screening component first, and then flow to the buffer component. The material outlet includes a first outlet and a second outlet 302. The first outlet is arranged corresponding to the screening component, and the second outlet 302 is arranged corresponding to the buffer component. The material that can pass through the screening component can flow to the conveyor belt 10 through the first outlet, and the material that cannot pass through the screening component can flow out of the second outlet 302 through the buffer component, so as to reduce the impact of the material on the conveyor belt 10.

[0032] By applying the technical solution of the present invention, a buffer device 30 is arranged on the mounting seat 20 of the belt conveyor, so that the material can be screened by the screening component of the buffer device 30, and the material with a smaller particle diameter and a lighter weight can pass through the screening component and fall onto the conveyor belt 10 through the first outlet; the material with a larger particle diameter and a heavier weight cannot pass through the screening component, and this part of the material will flow to the buffer component, and fall onto the conveyor belt 10 after being buffered by the buffer component. Through the cooperation of the screening component and the buffer component, the material that cannot cause a large impact on the conveyor belt 10 can fall directly on the conveyor belt 10, and the material that can cause a large impact on the conveyor belt 10 and may cause damage or even breakage of the conveyor belt 10 can fall onto the conveyor belt 10 after absorbing part of the kinetic energy through the buffer component, so as to reduce the damage to the conveyor belt 10. Through the technical solution of the present application, the possibility of damage to the conveyor belt 10 can be reduced, the service life of the conveyor belt 10 can be increased, and the impact on the mounting seat 20 can also be reduced, so as to further ensure the performance of the belt conveyor.

[0033] Specific reference Figure 2 and Figure 3 As shown, the buffer device 30 includes a box body 31, a sieve plate 32 and a buffer plate 33. The box body 31 is arranged on the mounting seat 20, a material inlet 301 is arranged on the top wall of the box body 31, and a second outlet 302 is arranged on the side wall of the box body 31. The sieve plate 32 is arranged in the box body 31, and the sieve plate 32 has a first side and a second side that are arranged opposite to each other, the first side is arranged close to the material inlet 301, and the first side is located above the second side. The buffer plate 33 is placed in the box body 31, and the buffer plate 33 is arranged at the second side. The material that does not pass through the sieve plate 32 can flow to the buffer plate 33, and the buffer plate 33 is provided with a guide structure for guiding the material to the second outlet 302. Through the above-mentioned arrangement, by arranging the first side edge of the sieve plate 32 to be located above the second side edge, that is, the sieve plate 32 is arranged obliquely in the box body 31, the material that enters the box body 31 through the material inlet 301 and fails to pass through the sieve plate 32 will fall on the buffer plate 33 under the action of gravity. The buffer plate 33 can absorb the kinetic energy of this part of the material and can slow down the falling speed of the material to reduce the impact on the conveyor belt 10. The guide structure on the sieve plate 32 can guide the material to the second outlet 302, and can also facilitate the flow of the material.

[0034] In some feasible embodiments of the present application, the distance between the end surface of the buffer plate 33 away from the bottom wall of the box body 31 and the bottom wall of the box body 31 gradually increases in the direction away from the second outlet 302. Through the above arrangement, the end surface of the buffer plate 33 away from the bottom wall of the box body 31 is inclined relative to the bottom wall of the box body 31, so that the material can flow to the second outlet 302 after falling onto the buffer plate 33, which facilitates the flow of the material.

[0035] Furthermore, a guide plate 36 is provided at the second outlet 302 of the box body 31 to further enhance the guiding effect on the material.

[0036] In the present application, the buffer device 30 further includes a first spring 34, which is disposed between the bottom plate of the box body 31 and the buffer plate 33, and is used to provide an elastic force to the buffer plate 33 in a direction away from the bottom plate of the box body 31. Through the above arrangement, the first spring 34 can further absorb the kinetic energy of the falling material, improve the buffering effect of the falling material, and reduce the impact of the material on the conveyor belt 10.

[0037] Specifically, the buffer device 30 further includes a partition plate 35, which is vertically arranged on the bottom wall of the box body 31, and the second side edge of the sieve plate 32 is arranged at one end of the partition plate 35 away from the bottom wall of the box body 31. A first outlet is arranged on the bottom wall of the box body 31, and the first outlet is arranged below the sieve plate 32 and located on the side of the partition plate 35 away from the buffer plate 33. Through the above arrangement, the partition plate 35 can prevent the material passing through the sieve plate 32 from failing to flow out through the first outlet and falling below the buffer plate 33, thereby affecting the cooperation between the buffer plate 33 and the first spring 34, ensuring the stability of the operation of the buffer assembly, and at the same time, it can also constrain the movement direction of the buffer plate 33, further improving the reliability of the buffer assembly.

[0038] Reference Figure 4 As shown, the mounting seat 20 has two mounting plates 21, and the two mounting plates 21 are relatively arranged on both sides of the conveyor belt 10 along the width direction. The belt conveyor also includes a correction device 40, and the correction device 40 is arranged between the conveyor belt 10 and the mounting plate 21. When the conveyor belt 10 deviates in the width direction, the correction device 40 can limit the deviation of the conveyor belt 10. When the conveyor belt 10 deviates, the tensioning force on the conveyor belt 10 will also increase. At this time, the conveyor belt 10 is more susceptible to damage after being impacted. Through the above-mentioned arrangement, the correction device 40 can prevent the conveyor belt 10 from deviating, and further ensure the working stability and service life of the conveyor belt 10.

[0039] In one embodiment of the present application, the deviation correction device 40 includes a baffle 41, a guide column 42 and a second spring 43. The baffle 41 is arranged on the side of the mounting plate 21 close to the conveyor belt 10, and the top of the baffle 41 is higher than the top of the conveyor belt 10. The guide column 42 is arranged on the side of the baffle 41 facing the mounting plate 21, and a guide hole is arranged on the mounting plate 21. The side of the guide column 42 away from the mounting plate 21 is movably arranged in the guide hole. The second spring 43 is sleeved on the guide column 42, and is used to provide an elastic force to the baffle 41 away from the mounting plate 21. Through the above arrangement, when the conveyor belt 10 deviates in the width direction, the conveyor belt 10 will collide with the baffle 41 and squeeze the baffle 41. At this time, the second spring 43 provides an elastic force for the baffle 41 to correct the deviation of the conveyor belt 10, prevent the conveyor belt 10 from deviating greatly, and then prevent the conveyor belt 10 from being torn under the impact of the material, thereby improving the service life of the conveyor belt 10.

[0040] Specifically in the present application, the belt conveyor further includes a repair device 50, which is disposed on the mounting seat 20 and is used to repair the conveyor belt 10. During the operation of the conveyor belt 10, the impact of the material may cause uneven holes to appear on the surface of the conveyor belt 10. As the conveyor belt 10 is continuously used, the degree of wear will gradually increase. By providing a repair device, the wear of the conveyor belt 10 can be repaired and the service life of the conveyor belt 10 can be increased.

[0041] Reference Figure 5 As shown, the repair device 50 includes a bracket 51, a liquid storage tank 52, a nozzle 53 and a brush 54. The bracket 51 is arranged on the mounting seat 20, the liquid storage tank 52 is arranged above the bracket 51, and the liquid storage tank 52 is provided with a repair liquid, the nozzle 53 is arranged on the bracket 51, and the nozzle 53 is connected with the liquid storage tank 52, and is used to spray the repair liquid to the conveyor belt 10, and the brush 54 is arranged on the bracket 51, and the brush 54 is arranged downstream of the nozzle 53 along the moving direction of the conveyor belt 10. Through the above arrangement, when the conveyor belt 10 needs to be repaired, the nozzle 53 can spray the repair liquid to the surface of the conveyor belt 10, and smooth it through the brush 54, so as to improve the service life of the conveyor belt 10.

[0042] Specifically in the present application, a plurality of nozzles 53 may be arranged at intervals along the width direction of the conveyor belt 10 to improve the repair effect. Correspondingly, the brush 54 may also be arranged to extend along the width direction of the conveyor belt 10 to ensure the smoothing effect of the brush 54, and the brush 54 may also be arranged to be inclined to the side opposite to the moving direction of the conveyor belt 10 in the horizontal direction to further improve the smoothing effect of the brush 54 and reduce the waste of the repair fluid.

[0043] Specifically in the present application, along the moving direction of the conveyor belt 10, the repair device 50 is arranged upstream of the buffer device 30 to prevent the repair device 50 from affecting the flow of materials.

[0044] In a specific embodiment of the present application, the bracket 51 includes a leg 511 and a support plate 512. One end of the leg 511 is arranged on the mounting seat 20, the support plate 512 is arranged on the other end of the leg 511, the nozzle 53 and the brush 54 are arranged on the support plate 512, and the leg 511 is provided with a height adjustment component for adjusting the distance between the support plate 512 and the conveyor belt 10. Through the above arrangement, when there is no need to repair the conveyor belt 10, the support plate 512 can be adjusted to move away from the conveyor belt 10 so that the nozzle 53 and the brush 54 avoid the moving materials; when the conveyor belt 10 needs to be repaired, the support plate 512 can be adjusted to move in the direction of the conveyor belt 10 to improve the spraying effect of the nozzle 53, so that the brush 54 can be closer to the conveyor belt 10, and ensure the repair effect.

[0045] In a specific embodiment of the present application, the mounting seat 20 has two mounting plates 21, which are relatively arranged on both sides of the conveyor belt 10 along the width direction, and a rotating roller 22 is arranged between the two mounting plates 21, and the rotating roller 22 can drive the movement of the conveyor belt 10. The belt conveyor also includes a speed detection device 60, which can detect the speed of the rotating roller 22. When the conveyor belt 10 is damaged and the speed of the rotating roller 22 is reduced, the speed detection device 60 can issue an alarm. When the conveyor belt 10 is damaged or torn, the friction between the conveyor belt 10 and the rotating roller 22 will decrease, and the speed of the rotating roller 22 will decrease. At this time, an alarm can be issued by the speed detection device 60 to promptly remind the staff to stop the machine for maintenance or start the repair device 50 to repair the conveyor belt 10.

[0046] Specifically, refer to Figure 6As shown, the rotation speed detection device 60 is arranged on the mounting plate 21 , and the rotation speed detection device 60 includes a fan 61 , a rotating plate 62 , a rotating shaft 63 , a button 64 , a shielding box 65 and a warning light 66 .

The outer cover of the fan 61 is provided with a shielding box 65, and the shielding box 65 is provided with a rotating shaft 63 and a rotating plate 62. The rotating plate 62 is fixedly arranged on the rotating shaft 63, and the button 64 is arranged on the side of the rotating shaft 63 close to the fan 61, and is electrically connected to the warning light 66. When the rotating roller 22 operates normally, the fan 61 will rotate around the rotating shaft 63 driven by the driving shaft 221, and the rotating plate 62 can be vertically deviated to one side of the fan 61 by controlling the weight of the rotating plate 62 when the fan is started; when the rotation speed of the rotating roller 22 decreases, the wind force of the fan 61 will decrease, so that the gravity on the rotating plate 62 will overcome the wind force provided by the rotation of the fan 61, and the button 64 is pressed to start the warning light 66 to notify the staff.
