[0003]为了解决现有技术中埋刮板输送机存在功率浪费且与后端装载车队配合不佳的技术问题，本申请提出了一种可半载运行的埋刮板输送机，解决了上述技术问题
[0016] This utility model discloses a half-load operation buried scraper conveyor. Without increasing the original machine body installation space, the conveying space in the middle section of the machine body is divided into two, forming two independent conveying channels on the left and right sides. Each conveying channel is equipped with an independent scraper chain assembly. At the same time, a rotatable flap is installed in the feed hopper. The flap's rotation shaft is mounted at the bifurcation point where the feed pipe of the feed hopper connects to both feed channels, controlling the stopping position of the flap after rotation. If the flap rotates to the two extreme positions on the left and right sides, it will abut against the inner wall of the left and right sides of the feed pipe respectively to block the feed on the corresponding side. When the flap rotates to the vertical center position, both feed channels and feed pipes are connected, allowing material in the feed hopper to enter only one of the conveying channels or both simultaneously. This enables the scraper conveyor to operate at full load or half load. In the case of road transport, when a lower transport speed is required, the half load operation mode can be activated to adapt to the convoy speed. Half load operation adapts to the convoy while reducing overall energy consumption, minimizing equipment wear, and solving the problem of overcapacity. Furthermore, the two conveying channels can operate independently without interference, ensuring uninterrupted maintenance.

Description
Technical Field
[0001] This utility model relates to the field of port machinery technology, specifically to a buried scraper conveyor that can operate under half load. Background Technology
[0002] A buried scraper conveyor is a type of transport equipment that continuously conveys bulk materials within a closed rectangular cross-section shell using a moving scraper chain. It is commonly used in industries such as metallurgy, mining, feed, and bulk grain storage and transportation at docks. It has advantages such as good sealing, flexible layout, and long conveying distance. However, it also suffers from problems such as excessive power consumption and excessive equipment wear leading to high maintenance costs. Due to space constraints, existing ship unloaders can only install one buried scraper conveyor at a time. The power of the reducer for each buried scraper conveyor needs to be configured according to the maximum tonnage. However, when unloading bulk grain from a large-tonnage (≥800t per hour) ship unloader, if the trucks are transported by road, the trucks in the convoy often cannot load the grain in time.

[0026] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0027] like Figure 1-6As shown, this utility model provides a submerged scraper conveyor capable of half-load operation, including a body 1, a feed hopper 2, and a discharge hopper 3. One end of the body 1 is formed as a head end 11 for discharging material, and the other end is formed as a tail end 12. The conveying space formed in the middle section of the body 1 is divided into two independent conveying channels 14 on the left and right sides by a vertical partition 13. Each conveying channel 14 is equipped with an independent scraper chain assembly 15. The feed hopper 2 is disposed on the body 1 and close to the tail end 12. Two feed channels 21 are formed in the feed hopper 2, and the two feed channels 21 are respectively connected to the corresponding conveying channels 14. The top of the feed hopper 2... The end has a feed pipe 22 that is connected to both feed channels 21. A rotatable flap 23 is installed inside the feed pipe 22. The pivot of the flap 23 is mounted at the bifurcation where the feed pipe 22 is connected to both feed channels 21. When the flap 23 rotates to the left and right extreme positions, it abuts against the left and right inner walls of the feed pipe 22 to block the feed channel 21 on the corresponding side. When the flap 23 rotates to the middle position, both feed channels 21 and the feed pipe 22 are connected. The discharge hopper 3 is installed at the head end 11. Two discharge channels 31 are formed inside the discharge hopper 3. The two discharge channels 31 are connected to the corresponding conveying channels 14.
[0028] The buried scraper conveyor with half-load operation provided by this utility model offers two operating modes: full-load operation and half-load operation. When only a lower conveying speed is required, the half-load operation mode can be activated to solve the problems of large production range and overcapacity. In the half-load operation mode, only the scraper chain assembly 15 on one side of the buried scraper conveyor is in working condition, which reduces energy consumption and overall equipment wear. Moreover, the two conveying channels 14 can work independently without interfering with each other, so that maintenance can be carried out without stopping the machine. The buried scraper conveyor with half-load operation provided by this utility model divides the conveying space inside the machine body 1 into two independent conveying channels 14 by a vertical partition 13, without increasing the original installation space of the machine body 1. Compared with arranging two separate scraper conveyors, it reduces the overall installation space and lowers the manufacturing cost of the equipment.
[0029] In a specific embodiment of this utility model, the bottom of the feed hopper 2 is forked and wraps around the left and right sides of the machine body 1, so that the corresponding feed channel 21 and the conveying channel 14 are connected on the side of the machine body 1. At the same time, the bottom of the feed hopper 2 is formed with an inclined plate 24 to introduce the material of the feed channel 21 into the bottom of the conveying channel 14, thereby ensuring that the material enters the conveying section of the scraper chain assembly 15.
[0030] In a preferred embodiment of the present invention, the feed hopper 2 is provided with a pointed structure 25 located on the upper part of the machine body 1 to form two feed channels 21 in the feed hopper 2, so as to guide the direction of material movement.
[0031] In one specific embodiment of this utility model, the scraper chain assembly 15 includes a reducer 155, a head wheel 153, a tail wheel 154, multiple forged chain links 151, and multiple scraper blades 152. Adjacent forged chain links 151 are connected by pins to form a chain. Each scraper blade 152 is fixedly connected to the corresponding forged chain link 151. The head wheel 153 and the tail wheel 154 are arranged at both ends of the chain. The head wheel 153 is mounted on the head end 11 via a head wheel shaft 1531, and the tail wheel 154 is mounted on the tail end 12 via a tail wheel shaft 1541. The reducer 155 is used to drive the head wheel shaft 1531. The main body of the reducer 155 is arranged on the head end 11 and located on the outer wall of the machine body 1.
[0032] In a specific embodiment of this utility model, reducers 155 are arranged on the outer walls of both the left and right sides of the head end 11. Two head wheel shafts 1531 driven by the two reducers 155 are coaxially configured. One end of the two head wheel shafts 1531 is mounted on the corresponding reducer 155, and a split bearing 156 is arranged at the mounting point. The other end of the two head wheel shafts 1531 is mounted in the same head sliding bearing 111. The head sliding bearing 111 is fixed at the junction of the two conveying channels 14. Although the two head wheel shafts 1531 are coaxially arranged, they are disconnected from each other. The head sliding bearing 111 serves as the middle force-bearing point inside the machine body 1 and supports both head wheel shafts 1531.
[0033] In a specific embodiment of this utility model, bearings 121 with seats are arranged on the outer walls of both the left and right sides of the tail end 12. Two tail wheel shafts 1541 are coaxially arranged in the two bearings 121. One end of the two tail wheel shafts 1541 is mounted on the corresponding bearing 121, and the other end of the two tail wheel shafts 1541 is mounted in the same tail sliding bearing 122. The tail sliding bearing 122 is fixed at the junction of the two conveying channels 14. Although the two tail wheel shafts 1541 are coaxially arranged, they are disconnected from each other. The tail sliding bearing 122 serves as the middle force-bearing point in the machine body 1 and supports the two head wheel shafts 1531.
[0034] The head wheel axle 1531 and tail wheel axle 1541 in the two conveying channels 14 are independent, so that the chains in the two conveying channels 14 can work independently without interfering with each other.
[0035] In one specific embodiment of this utility model, the tail end 12 is further equipped with a tensioning device 16 to tension the chain. The tensioning device 16 includes a sliding assembly, two sets of sliding grooves 161, and two sets of adjusting screws 164. The two sets of sliding grooves 161 are respectively arranged on the left and right sides of the tail end 12. The extending direction of the sliding grooves 161 is the same as the extending direction of the body 1. The sliding assembly is slidably engaged with two of the sliding grooves 161. It should be noted that the sliding groove 161 on one side is arranged on the outer wall of the tail end 12 to assemble the sliding plate 162. At the same time, a clearance space groove needs to be left on the side wall of the tail end 12 to avoid the connecting rod 163 and the tail wheel shaft 1541. The sliding assembly includes... It includes two sliding plates 162 and a connecting rod 163 connecting the two sliding plates 162. The connecting rod 163 extends horizontally through the machine body 1, and the middle of the connecting rod 163 is connected to the tail sliding bearing 122. The two sliding plates 162 are respectively fitted on the outer wall of the tail end 12, and the sliding plates 162 are connected to the seat bearing 121. Two sets of adjusting screws 164 are respectively arranged on the left and right sides of the tail end 12. The extension direction of the adjusting screws 164 is the same as the extension direction of the machine body 1. Each adjusting screw 164 is fitted with two nuts. One nut is fixed on the machine body 1, and the other nut is fixed on the sliding plate 162, specifically on the bracket on the sliding plate 162.
[0036] In a preferred embodiment of this utility model, a polymer scraper 1521 made of wear-resistant material is fixed on the scraper blade 152, which ensures the rigidity of the scraper blade while effectively reducing the noise generated by friction.
[0037] In a preferred embodiment of this utility model, a guide rail frame 141 is provided on the top plate of the conveying channel 14. Wear-resistant strips 142 made of ultra-high molecular weight polyethylene are arranged at the opposite positions of the guide rail frame 141 and the bottom plate of the conveying channel 14. The extension direction of the wear-resistant strips 142 is the same as the extension direction of the machine body 1. While realizing the guiding role during the chain operation, the wear-resistant strips 142 also reduce the noise generated by the friction between the chain and the steel plate of the machine body 1.
[0038] In a preferred embodiment of this utility model, the flap 23 is driven by an electric push rod assembly 26. The electric push rod assembly 26 includes an electric push rod 262 and multiple position sensors. The electric push rod 262 includes a cylinder 261 and a push rod 262 that can extend out of the cylinder 261. The cylinder 261 is connected to the outside of the feed hopper 2. The push rod 262 drives the rotating shaft of the flap 23 through a bend 263. One end of the bend 263 is hinged to the push rod 262, and the other end of the bend 263 is fixedly connected to the rotating shaft of the flap 23. The position sensors are arranged on the feed hopper 2 to sense the position of the flap 23 and feed the signal back to the control system.
[0039] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
