Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying device technology, specifically a chain conveyor. Background Technology
[0002] The FU chain conveyor, also known as a "chain conveyor," is a new type of conveyor used for horizontal or inclined conveying of powdery and small granular materials at an angle of ≤15°. It features long service life, good sealing, safety, and high efficiency, and is widely used in industries such as building materials, chemicals, food processing, mining, machinery, and transportation.
[0003] A search revealed a Chinese patent for a chain conveyor, publication number CN212798282U, which includes a housing, a drive motor disposed outside the housing, and a feeding mechanism disposed inside the housing. The housing has a feed inlet at one end and several discharge ports at the bottom, with discharge valves installed on the discharge ports.
[0004] The above-mentioned device has a notch at the discharge port of the chain guide rail, and the length of the notch is at least the length of two chain links, so that the conveying chain passing through this point is in a suspended state, making it easier for the material to fall at the discharge port. The chain that passes through does not continue to carry the material, thereby avoiding the accumulation of material at the machine head and causing jamming. The baffle at the non-discharge point is parallel to the track and does not affect the movement of the material with the chain.
[0005] However, its conveying chamber structure is relatively simple. When conveying materials with high viscosity and moisture content, the wet materials are easy to adhere to the bottom shell of the pipe. After a long period of shutdown, the materials may dry and clump together and adhere to the bottom plate of the conveyor, which can easily affect the subsequent scraper conveying. In addition, the bottom shell of the conveyor is located below the conveyor chain. After a lot of materials adhere, the cleaning process is more difficult, which may lead to excessive downtime and affect work efficiency. At the same time, when adjusting the position of the discharge port, the whole thing needs to be disassembled, which is a rather cumbersome process. Utility Model Content
[0006] The purpose of this invention is to provide a chain conveyor that can effectively solve the problems in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A chain conveyor includes a conveyor housing, a top plate installed at the top of the conveyor housing, a drive motor installed at the front position of the top of the top plate, and transmission rollers rotatably installed at the front and rear positions inside the conveyor housing.

The adjusting motor is installed below the first movable plate at a central position on one side. A transmission gear is installed at the end of the drive shaft of the adjusting motor. An adjusting rack meshing with the transmission gear is provided at the central position of the bottom of the first movable plate. The first movable plate is meshed with the transmission gear and the drive shaft of the adjusting motor through the adjusting rack.
[0010] Preferably, a connecting bolt post 1 is provided on one side of both the movable plate 1 and the movable plate 2 near the connection point. A connecting plate is movably installed on the outer ring of the connecting bolt post 1, and a fixing nut is threadedly connected to the outer ring of the connecting bolt post 1 on one side of the connecting plate.
[0011] Preferably, a connecting bolt post 2 that is compatible with the connecting piece and the fixing nut is provided on one side of the conveyor housing and near the connection between the first movable plate and the second movable plate. The second movable plate is detachably connected to the conveyor housing through the connecting piece, the fixing nut and the second fixing bolt post 2.
[0012] Preferably, the second movable plate is detachably connected to the first movable plate via a fixing nut, a fixing bolt column, and a connecting piece, and a handle is fixedly connected to the center of the front end of the second movable plate.

[0014] Preferably, sealing baffles are installed at both the front and rear ends of the conveyor housing by fixing bolts, and reinforcing columns are fixedly connected at the bottom of the conveyor housing and at the joint between each movable plate one and movable plate two.
[0015] Preferably, the top of the conveyor housing is provided with a plurality of feed inlets, and the top of each feed inlet is provided with a cover plate.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This utility model, by setting up an adjusting rack, adjusting motor, movable plate one, movable plate two, transmission gear, and connecting piece to cooperate with each other, can remove movable plate one and movable plate two from the inside of the conveyor casing after conveying materials with high viscosity and moisture such as slag. After that, personnel can clean the bottom casing and avoid long downtime that could cause impurities to adhere.
[0018] Furthermore, during cleaning, movable plate one and movable plate two are exposed outside the conveyor housing, which can prevent the conveyor chain from causing significant interference to the cleaning of movable plate one and movable plate two.

[0025] 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. Example 1
[0026] Combination Figures 1-4A chain conveyor includes a conveyor housing 1, a top plate 2 installed at the top of the conveyor housing 1, a drive motor 3 installed at the front position of the top of the top of the top plate 2, and transmission rollers rotatably installed at the front and rear positions inside the conveyor housing 1. The outer ring of the transmission rollers is connected to a conveyor chain 5. The drive shaft of the drive motor 3 is connected to one of the transmission rollers through the transmission chain. A discharge assembly 6 is provided inside the conveyor housing 1.
[0027] See Figure 2 and Figure 3 Furthermore, the discharge assembly 6 includes an adjusting motor 8, a first movable plate 7, and a second movable plate 11. A groove adapted to the first movable plate 7 and the second movable plate 11 is provided on one side of the conveyor housing 1 near its lower position. The first movable plate 7 and the second movable plate 11 are slidably installed within the groove of the conveyor housing 1, and two second movable plates 11 are provided on both sides of each first movable plate 7. The adjusting motor 8 is installed below the first movable plate 7, in a central position on one side. A transmission gear 10 is installed at the end of the drive shaft of the adjusting motor 8. At the bottom center of the movable plate 7, there is an adjusting rack 9 that meshes with the transmission gear 10. The movable plate 7 is connected to the transmission gear 10 and the drive shaft of the adjusting motor 8 through the adjusting rack 9. The front and rear ends of the conveyor housing 1 are equipped with sealing baffles 14 by fixing bolts. The bottom of the conveyor housing 1 and at the joint between each movable plate 7 and movable plate 11 are fixedly connected with reinforcing columns 13. The top of the conveyor housing 1 is provided with several feed inlets 4, and the top of the feed inlets 4 is provided with a cover plate.
[0028] Specifically, during normal material conveying, the movable plate 11 can be connected to the conveyor housing 1 via the connecting piece 12 and the fixing nut. Then, the cover plate on the feed inlet 4 at a suitable position can be removed, and the drive motor 3 can be started to drive the transmission roller to rotate, thereby driving the conveyor chain 5 to rotate inside the conveyor housing 1 to convey the material entering the conveyor housing 1. Simultaneously, multiple movable plates 7 and 11 are installed on the conveyor housing 1. The movable plates 7 and 11 support the material. Movable plate 7 is connected to the adjusting motor via the adjusting rack 9 and transmission gear 10. The drive shaft of motor 8 is engaged, so when the material arrives, the drive shaft of motor 8 can be adjusted to rotate, thereby driving the movable plate 7 to extend out of the conveyor housing 1 for material discharge. That is, when the material is moved to the extended movable plate 7 by the rotation of the conveyor chain 5, since the movable plate 7 has moved out of the conveyor housing 1, it will not lift the material. At this time, the material will fall out of the conveyor housing 1 for discharge. Multiple movable plates 7 are evenly installed on the conveyor housing 1. The movable plates 7 in the appropriate positions can be flexibly adjusted to open in the above manner so that the material can be discharged in different positions. Example 2
[0029] See Figure 2 and Figure 4 Furthermore, based on Embodiment 1, a connecting bolt post 1 is provided on one side of both movable plate 1 7 and movable plate 2 11 near the connection point. A connecting piece 12 is movably installed on the outer ring of the connecting bolt post 1. A fixing nut is threadedly connected to the outer ring of the connecting bolt post 1 and located on one side of the connecting piece 12. A connecting bolt post 2, which is compatible with the connecting piece 12 and the fixing nut, is provided on one side of the conveyor housing 1 near the connection point of movable plate 1 7 and movable plate 2 11. Movable plate 2 11 is detachably connected to the conveyor housing 1 through the connecting piece 12, the fixing nut, and the fixing bolt post 2. Movable plate 2 11 is detachably connected to movable plate 1 7 through the fixing nut, the fixing bolt post 1, and the connecting piece 12. A handle is fixedly connected to the center of the front end of movable plate 2 11. The top surface height of movable plate 2 11 and movable plate 1 7 is compatible with the conveyor chain 5. The top surfaces of movable plate 1 7 and movable plate 2 11 are coated with epoxy anti-corrosion coating.
[0030] Specifically, after conveying slag or other sticky and wet materials, movable plate 7 can be retracted into the conveyor housing 1 as needed. Then, movable plate 7 and movable plate 11 can be reconnected together by connecting piece 12 and fixing nut. At this time, movable plate 11 is not connected to the conveyor housing 1. Subsequently, the drive shaft of motor 8 can be adjusted to rotate so that movable plate 7 and movable plate 11 can be removed from the inside of the conveyor housing 1. After removal, personnel can use a cleaning brush or other tools in conjunction with water to clean the top surfaces of movable plate 11 and movable plate 7. After cleaning, they can be reset for subsequent use.
[0031] In actual operation, when the material is being conveyed normally, the movable plate 11 can be connected to the conveyor housing 1 through the connecting piece 12 and the fixing nut. Then, the cover plate on the feed port 4 at the appropriate position can be removed, and the drive motor 3 can be started. Since the drive shaft of the drive motor 3 is connected to the transmission roller inside the conveyor housing 1 through the transmission chain, the transmission roller can be driven to rotate. The transmission roller can drive the conveying chain 5 to rotate inside the conveyor housing 1 to convey the material entering the conveyor housing 1.
[0032] Meanwhile, multiple movable plates 1 7 and movable plates 2 11 are slidably installed on the conveyor housing 1. The movable plates 1 7 and movable plates 2 11 play the role of lifting the material. Since the movable plate 1 7 is connected to the drive shaft of the adjusting motor 8 through the adjusting rack 9 and the transmission gear 10, and the movable plate 2 11 is connected to the conveyor housing 1, when the material arrives, the drive shaft of the adjusting motor 8 can be rotated to drive the movable plate 1 7 to extend out of the conveyor housing 1 for material discharge.
[0033] That is, when the material is conveyed to the movable plate 7 as the conveyor chain 5 rotates, the movable plate 7 has been moved out of the inside of the conveyor housing 1, so it will not lift the material. At this time, the material will fall from the inside of the conveyor housing 1 for discharge. Multiple movable plates 7 are evenly installed on the conveyor housing 1. The movable plates 7 in the appropriate positions can be flexibly adjusted to open in the above manner, so that the material can be discharged in different positions.
[0034] Meanwhile, after conveying slag or other sticky and wet materials, the movable plate 17 and the movable plate 21 can be reconnected together by connecting piece 12 and fixing nut after the movable plate 17 is retracted into the conveyor housing 1 as needed. This step can refer to the existing bolt and nut connection.
[0035] At this time, the second movable plate 11 is not connected to the conveyor housing 1. Subsequently, the drive shaft of the motor 8 can be adjusted to rotate, so that both the first movable plate 7 and the second movable plate 11 can be removed from the inside of the conveyor housing 1. After removal, personnel use a cleaning brush or other tools in conjunction with water to clean the top surfaces of the second movable plate 11 and the first movable plate 7. By cleaning off the impurities, it can be prevented that the impurities solidify on the first movable plate 7 and the second movable plate 11 during the shutdown process, thereby preventing a significant impact on subsequent conveying. After cleaning is completed, it can be reset again, that is, the second movable plate 11 can be reconnected to the conveyor housing 1 through the connecting piece 12 and the fixing bolts, while the first movable plate 7 can be retracted into the inside of the conveyor housing 1 for subsequent use.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
