Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and in particular to a scraper conveyor with a detachable central trough. Background Technology

[0002] A chain conveyor (chain plate conveyor) is a mechanical device that uses a chain to pull metal or plastic chain plates in a cyclical motion to achieve continuous material transport. Its core components include a drive unit, sprockets and chains, conveyor chain plates, and a support structure. Chain conveyors are currently widely used in industries such as metallurgy, mining, chemicals, and building materials, and can transport bulk materials (such as ore and coal) as well as packaged goods (such as castings and packaging boxes). During the daily use of chain conveyors, the middle plate used to carry and transport materials will be worn by the chain plates, which can easily cause grooves or pits and lead to material jamming. It is necessary to replace the middle plate. However, the middle plate of existing chain conveyors is mostly a whole piece, and replacing the whole middle plate is costly. Therefore, we propose a scraper conveyor with a detachable middle groove. Utility Model Content

[0003] The technical problem this utility model aims to solve is to overcome the existing defects and provide a scraper conveyor with a detachable central trough. The detachable and removable central plates of this scraper conveyor are installed by insertion, and by removing the bolts at the fixing feet, the detachable and removable central plates can be pulled outwards for replacement of worn individual plates, reducing the maintenance cost of the scraper conveyor. Furthermore, it has a reliable conveying and discharging unit. The main unloading platform is installed at the tail of the scraper conveyor and plays a major role in unloading. Some sticky materials easily adhere to the scraper plates, thus sticking to the scraper plates and bypassing the main unloading platform. Through the opening of the auxiliary discharge hole, these small amounts of material can be discharged downwards, ensuring that all transported materials are unloaded, effectively solving the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a scraper conveyor with a detachable central trough, comprising a main trough body, a central plate disassembly unit, and a conveying and discharging unit, characterized in that: The main tank has a U-shaped vertical cross-section. The middle plate disassembly unit includes a disassembly and assembly middle plate, an outer fixing plate, fixing feet, a hand latch groove, a transmission chain, and a scraper. A row of horizontal disassembly and assembly middle plates is inserted inside the main trough. The disassembly and assembly middle plates pass through the right side of the main trough and are inserted into the inner wall on the left side of the disassembly and assembly middle plate. A rectangular outer fixing plate is fixedly connected to the outer right end of the disassembly and assembly middle plate. A set of fixing feet is fixedly connected to the upper and lower edges of the outer fixing plate. The fixing feet are fixedly connected to the outer right wall of the main trough by bolts. A hand latch groove is opened at the middle position of the outer side of the outer fixing plate. Two longitudinal and parallel transmission chains are installed inside the main trough. The transmission chains are located on the outer side of the disassembly and assembly middle plates. A ring of scrapers is fixedly connected at equal intervals on the outer ring side of the transmission chains. The scrapers are perpendicular to the transmission chains. Conveying and discharging unit: installed at the right end and lower side of the main trough.

[0005] A longitudinal row of disassembly and assembly plates, combined with the U-shaped main trough, forms the central trough structure of the scraper conveyor, providing a material conveying channel. A drive chain drives the scraper plates to move in a cycle, scraping the material and transporting it backward. The disassembly and assembly plates pass through the right side of the main trough and are inserted into the inner wall on the left side. An outer fixing plate is used to limit and secure the disassembly and assembly plates. By adding bolts at the fixing feet, the disassembly and assembly plates can be fixed to the right side of the main trough, thus securing them. By removing the bolts at the fixing feet, the disassembly and assembly plates can be pulled out to replace worn individual plates, reducing the maintenance cost of the scraper conveyor. The hand grip slot facilitates the worker's grip, making it easy to insert and remove the disassembly and assembly plates.

[0006] Furthermore, the middle plate disassembly unit also includes a rotating shaft, shaft locking blocks, sprockets, a reducer, and a motor. A shaft locking block is fixedly connected to the front and rear ends of the main trough. Both ends of the shaft locking blocks are bolted to the main trough. A rotating shaft is rotatably connected between two adjacent shaft locking blocks laterally. Two sprockets are fitted and fixedly connected to the middle section of the rotating shaft. Each set of two sprockets is symmetrically distributed left and right. A transmission chain is installed between corresponding front and rear sprockets. A reducer is fixedly installed at the shaft locking block on the right front side. The motor is installed adjacent to the reducer. The input shaft of the reducer is fixedly connected to the output shaft of the motor, and the output shaft of the reducer is fixedly connected to the right end of the front rotating shaft. The motor provides power output, and the reducer converts the motor's speed into torque, thereby driving the rotating shaft to rotate at a low and stable speed, improving the material carrying capacity. The rotating shaft drives the transmission chain to rotate via the sprockets installed on the outer side, thereby moving the scraper plate.

[0007] Furthermore, the conveying and discharging unit includes a main unloading platform and an outer clamping block. The main unloading platform is installed at the rear end of the main trough, and it is also installed in an insert manner. A triangular outer clamping block is fixedly connected to the right end of the main unloading platform. The outer clamping block has the same fixing feet as the outer fixing plate, and a similar hand-locking groove is provided in the middle. The front end of the main unloading platform is aligned with the rear end of the last side disassembly and assembly plate, and the upper rear side of the main unloading platform is an inclined end face. The main unloading platform adopts the same installation and fixing method as the disassembly and assembly plate, and plays the main unloading role at the tail of the scraper conveyor. The material pushed backward along the disassembly and assembly plate will flow out obliquely downward when passing the inclined surface behind the main unloading platform.

[0008] Furthermore, the conveying and discharging unit also includes support columns, feet, and a secondary discharge hole. A row of support columns is fixedly connected to both the left and right sides of the lower end of the main trough. A circular foot is fixedly connected to the lower end of each support column. A square secondary discharge hole is opened at the rear of the lower end of the main trough. The support columns are used to support the main trough to a certain height, thereby ensuring the secondary discharge hole has a suitable height above the ground, facilitating the downward leakage of material from the secondary discharge hole. Some sticky materials easily adhere to the scraper blade, thus adhering to it and bypassing the main unloading platform. During the return journey along the scraper blade on the underside of the disassembly and assembly plate, under the action of gravity, the material falls to the bottom of the main trough and is scraped forward by the scraper blade. The secondary discharge hole allows these small amounts of material to leak downwards, ensuring that all transported material is unloaded.

[0009] Furthermore, the middle plate disassembly unit also includes a support platform and a mounting plate. A horizontal mounting plate is fixedly connected to the front right side of the main groove body, and the support platform is fixedly connected to the upper end of the mounting plate. The motor is mounted and clipped onto the upper end of the support platform. The mounting plate is used for mounting the support platform, which supports the motor, and its upper arc-shaped structure can lock the motor in place.

[0010] Furthermore, the middle plate disassembly unit also includes a fixing ring and a control console. The upper end of the support platform is fixedly connected to the fixing ring by bolts. The fixing ring has an Ω-shaped structure and is secured to the outside of the motor. A control console is installed on the upper side of the mounting plate, located at the right end of the support platform. The input end of the motor is electrically connected to the output end of an external power supply through the control console. The fixing ring is used to secure the motor, thereby ensuring that the motor can operate stably for a long time without shaking. The control console is used to adjust the motor speed and control its start and stop.

The disassembly and assembly plates of this chain conveyor are installed by insertion. By adding bolts at the fixing feet, the disassembly and assembly plates can be fixed to the right side of the main trough, thereby securing the disassembly and assembly plates. By removing the bolts at the fixing feet, the disassembly and assembly plates can be pulled outward to replace individual disassembly and assembly plates that have become worn, reducing the maintenance cost of the scraper conveyor. The hand grip groove is easy for workers to grip, thus facilitating the insertion and removal of the disassembly and assembly plates. 2. It also has a reliable conveying and discharging unit. The main unloading platform is installed at the tail of the scraper conveyor and plays the main unloading role. Some sticky materials are easy to stick to the scraper and pass through the main unloading platform. They return along the scraper plate under the middle plate during disassembly and assembly. Under the action of gravity, the material falls into the bottom of the main trough and is scraped forward by the scraper plate. Through the opening of the auxiliary discharge hole, these small amounts of material can be leaked downwards to ensure that all transported materials can be unloaded. 3. The disassembly and assembly plates of this chain conveyor are installed by insertion.

The front end of the main unloading platform 31 is aligned with the rear end of the last side disassembly and assembly plate 21. The upper rear side of the main unloading platform 31 is an inclined end face. The main unloading platform 31 adopts the same installation and fixing method as the disassembly and assembly plate 21. It plays the main unloading role at the tail of the scraper conveyor. The material pushed backward along the disassembly and assembly plate 21 will flow out obliquely downward when passing the inclined surface of the rear side of the main unloading platform 31.

[0024] The conveying and discharging unit 3 also includes support columns 33, feet 34, and auxiliary discharge holes 35. A row of support columns 33 is fixedly connected to the left and right sides of the lower end of the main trough 1. A circular foot 34 is fixedly connected to the lower end of each support column 33. A square auxiliary discharge hole 35 is opened at the rear position of the lower end of the main trough 1. The support columns 33 are used to support the main trough 1 to a certain height, so that the auxiliary discharge hole 35 has a suitable height from the ground, which facilitates the material at the auxiliary discharge hole 35 to leak downward. Some sticky materials are easy to stick to the scraper 26, thus adhering to the scraper 26 and bypassing the main unloading platform 31. They return with the scraper 26 under the disassembly and assembly plate 21. Under the action of gravity, the material falls to the bottom of the main trough 1 and is scraped forward by the scraper 26. Through the opening of the auxiliary discharge hole 35, these small amounts of material can be leaked downward, ensuring that all transported materials can be unloaded.

[0027] The working principle of the scraper conveyor with a detachable central trough provided by this utility model is as follows: The detachable central plate 21 of this chain conveyor is installed by insertion. A longitudinal row of detachable central plates 21 and the U-shaped main trough 1 are combined to form the central trough structure of the scraper conveyor, which is used to provide a material conveying channel. The motor 211 provides power output, and the reducer 210 converts the speed of the motor 211 into torque, thereby driving the rotating shaft 27 to rotate at a low speed and improve the material carrying capacity. The rotating shaft 27 drives the transmission chain 25 to rotate through the sprocket 29 installed on the outside, thereby driving the scraper 26 to move and scrape the material to transport it backward. The disassembly and assembly plate 21 passes through the right side of the main trough 1 and is inserted into the inner wall on the left side of the disassembly and assembly plate 21.

The hand grip groove 24 is easy for the worker's hand to grip, thus facilitating the insertion and removal of the disassembly and assembly plate 21. This chain conveyor also has a reliable conveying and discharging unit 3. The main unloading platform 31 adopts the same installation and fixing method as the disassembly and assembly middle plate 21. It plays the main unloading role at the tail of the scraper conveyor. The material pushed backward along the disassembly and assembly middle plate 21 will flow out obliquely downward when passing the inclined surface behind the main unloading platform 31. The support column 33 is used to support the main trough 1 to a certain height, so that the auxiliary discharge hole 35 has a suitable height above the ground, which facilitates the material at the auxiliary discharge hole 35 to leak downward. Some sticky materials are easy to stick to the scraper plate 26, thus adhering to the scraper plate 26 and bypassing the main unloading platform 31. They return along the scraper plate 26 on the underside of the disassembly and assembly middle plate 21. Under the action of gravity, the material falls into the bottom of the main trough 1 and is scraped forward by the scraper plate 26. Through the opening of the auxiliary discharge hole 35, these small amounts of material can be leaked downward, ensuring that all transported materials can be unloaded. In addition, the mounting plate 215 is used for mounting the support platform 212, which supports the motor 211, and its upper arc structure can lock the motor 211 in place. The fixing ring 213 is used to fasten the motor 211, thereby ensuring that the motor 211 can work stably for a long time without shaking. The control console 214 is used to adjust the speed of the motor 211 and control its start and stop.
