[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.
[0023] As shown in the prior art, Figs. 3 to 5 The existing chain conveyor mainly uses the tensioned down-pulling chain to transport the material in the feed inlet through the friction between the scraper and the bottom and side wall of the box. However, when the material being transported contains hard foreign matters such as steel bars and steel plates, these foreign matters will move to the discharge outlet together with the material. Some foreign matters will fall into the discharge chute, while the long or large foreign matters will enter between the sprocket and the chain, causing the sprocket and the chain to be unable to effectively mesh and be jammed. It is difficult to remove the jammed foreign matter and eliminate the fault. Only by reversing the head wheel to reverse the chain can the foreign matter be removed. When reversed, the chain will be jammed at the interface between the lower box and the discharge chute, so that the sprocket cannot be reversed. Sometimes, the chain will be pulled off or the resistance will be too large, causing the motor to overload and stop.
[0024] To solve the above problems, as shown in the present application, Figs. 1 to 2 The present application provides a chain conveyor, which comprises a box 1 and a feeding device 2. The feeding device 2 comprises a sprocket 21 and a chain 22 for transporting material. The chain 22 is in transmission connection with the sprocket 21. One end of the box 1 is provided with a feed inlet 12 at the top, and the other end is provided with a discharge outlet 13 at the bottom. The discharge outlet 13 is provided with a guide plate 3 and a mounting end 211 for mounting the guide plate 3. The guide plate 3 is inclinedly arranged from the mounting end 211 to the discharge direction of the discharge outlet 13.
[0025] The utility model discloses a guide plate 3 design is introduced, effectively solved the difficulty and inconvenience of current chain conveyor when processing rigid sundries 4, improved the reliability and operating efficiency of equipment, and the discharge port 13 of being equipped with the guide plate 3 can effectively guide rigid sundries 4 to separate from the sprocket 21 and chain 22, prevent rigid sundries 4 from entering the meshing area of sprocket 21 and chain 22 and stay and cause sprocket 21 and chain 22 to be effectively meshed and jam, thereby significantly reduce the risk of equipment blocking and damage caused by sundry jam, increase the reliability and continuous running time of equipment, the inclination of guide plate 3 can ensure that sundries can naturally move to the discharge port 13, so that the operator can more easily remove sundries.
[0026] In the embodiment, the feeding direction is shown by arrow A, and the discharging direction is shown by arrow B.
[0027] Specifically, in the embodiment, the inclination angle α between the guide plate 3 and the mounting end 211 satisfies 20°≤α≤25°. Setting an appropriate inclination angle range can ensure that the guide plate 3 will not cause the chain 22 or sundries to fall off due to an excessively large angle when it is reversely rotated. The guide plate 3 within the inclination angle range can stably guide the chain 22 and sundries to flow to the discharge port 13, so that the conveying system runs more smoothly and reliably, and good conveying efficiency can be maintained whether it is running forward or reversely at an appropriate angle. When α<20°, a small inclination angle may cause sundries to accumulate on the guide plate 3, especially when it is reversely rotated, the sundries may be retained on the guide plate 3, and the friction between the chain 22 and the guide plate 3 may be increased, which may cause the chain 22 to be severely worn and the service life of the equipment to be shortened. When α>25°, an excessively large inclination angle may cause the chain 22 to fall off or slide off when it is reversely rotated, and the guide plate 3 cannot effectively guide the sundries or material to the discharge port 13. An excessively large inclination angle may increase the instability between the guide plate 3 and the chain 22, especially under high-speed operation or heavy load, which may cause the chain 22 to swing or jump, affecting the smooth running of the system.
[0028] Specifically, the guide plate 3 includes a first guide plate 313 and a second guide plate 323, and the first guide plate 313 and the second guide plate 323 have a discharging gap 33 for discharging. The discharging gap 33 between the first guide plate 313 and the second guide plate 323 can ensure that the material flow is branched to the discharge port 13, so that the material is smoothly discharged from the conveyor instead of being accumulated or blocked between the guide plates 3, and the overall conveying efficiency is improved.
[0029] Specifically, the width of the chain 22 is H1, and the width H2 of the discharging gap 33 satisfies H2<H1. The discharging gap 33 is narrower than the width of the chain 22, which can ensure that the material is effectively branched and smoothly discharged when passing through the discharging gap 33, and the chain 22 will not fall off from the discharging gap 33 when the sprocket 21 is reversely rotated.
[0030] Specifically, the guide plate 3 is a long strip-shaped guide plate, the long strip-shaped guide plate 3 is more in line with the shape of the chain 22 and is more easy to support the chain 22, thereby preventing the chain 22 from being stuck in the discharge port when the sprocket 21 reverses.
[0031] Specifically, the discharge port 13 further comprises a discharge chute 131 arranged along the discharging direction of the discharge port 13, and the side edge of the guide plate 3 is connected to the discharge chute 131. The discharge chute 131 is arranged along the discharging direction of the discharge port 13, and the connection between the guide plate 3 and the discharge chute 131 ensures the stability and smoothness of the material during discharging. Such a design can ensure that the material does not deviate or block during discharging, effectively prevents the material from overflowing or splashing during discharging, ensures the smooth discharge of the material along the predetermined path, avoids the problems of cleaning and production line shutdown caused by overflow, and simplifies the cleaning and maintenance work.
[0032] In addition to the preferred embodiments described above, the utility model also has other implementation manners, and all other embodiments obtained by those skilled in the art based on the embodiments in the utility model without creative labor belong to the scope of the utility model claimed.
