Description

A buried scraper feeder Technical Field

[0001] This application relates to the field of coal feeder technology, and more specifically, to a buried scraper coal feeder. Background Technology

[0002] A submerged scraper feeder is a commonly used piece of equipment in coal conveying systems. Its working principle involves a scraper chain buried beneath the coal pile pushing coal to a conveyor belt or other locations requiring transport. The submerged scraper feeder utilizes the coal's own friction and the drag force of the scraper chain to create a continuous coal seam flow within the feeder body along the chain's direction of movement. This flow continuously from the inlet to the outlet (entering the coal mill), achieving continuous, uniform, and quantitative material conveying.

[0003] Existing scraper feeders typically use a motor in conjunction with a chain and gear transmission to drive the scraper chain for conveying coal. However, when the chain and gear transmission is subjected to external impact or excessive torque, they are prone to bending and deformation, which can lead to slack in the gear and chain transmission. If the chain tension is not adjusted, it can easily affect the transmission effect and thus affect the conveying of coal.

[0035] Referring to Figures 1 to 5, this application provides a buried scraper feeder 1, including a housing 11, a conveying assembly 12, and a drive assembly 13. The housing 11 has an inner cavity and an inlet 111 and an outlet 112 communicating with the inner cavity. The conveying assembly 12 is disposed in the inner cavity and located between the inlet 111 and the outlet 112, for conveying coal from the inlet 111 to the outlet 112. The drive assembly 13 includes a motor 131 and a chain drive mechanism. The motor 131 is disposed in the housing 11, and the chain drive mechanism is connected between the motor 131 and the drive roller 121 of the conveying assembly 12. The chain drive mechanism performs transmission when the motor 131 is started, so as to make the conveying assembly 12 run.

[0036] In some embodiments, the conveying assembly 12 includes a drive roller 121, a conveyor belt 122, and a scraper 123. The drive roller 121 is rotatably disposed on the housing 11. The conveyor belt 122 is sleeved on the drive roller 121 and is capable of operating when the drive roller 121 rotates. The scraper 123 is disposed on the outside of the conveyor belt 122 and is capable of pushing coal to form a coalbed flow when the conveyor belt 122 is running, continuously causing coal to flow from the coal inlet to the discharge outlet 112.

[0037] In some embodiments, the chain drive mechanism includes a first gear 132, a second gear 133, and a chain 134. The first gear 132 is disposed on the drive shaft of the motor 131, the second gear 133 is disposed on the drive roller shaft 121 of the conveying assembly 12, and the chain 134 is sleeved on the first gear 132 and the second gear 133. When the motor 131 starts, the drive shaft of the motor 131 drives the first gear 132 to rotate circumferentially. The first gear 132 drives the second gear 133 to rotate circumferentially via the chain 134. When the second gear 133 rotates circumferentially, it drives the drive roller shaft 121 of the conveying assembly 12 to rotate, thereby causing the conveyor belt 122 to run.

[0038] In some embodiments, the drive assembly 13 is disposed on the outer wall of the housing 11. For example, in a specific configuration, one end of a drive roller 121 of the conveying assembly 12 extends outside the housing 11, so that the drive assembly 13 located on the outer wall of the housing 11 can connect to the drive roller 121 and drive the drive roller 121 to rotate. This configuration can prevent coal from contaminating the drive assembly 13 and affecting its driving effect.

[0039] In some embodiments, the submerged scraper feeder 1 further includes an adjustment assembly 14, which includes an adjustment gear 141 and a first drive member 142. The adjustment gear 141 is movably and rotatably disposed on the housing 11 and meshes with the chain 134 of the chain drive mechanism. The first drive member 142 is disposed on the housing 11 and connected to the adjustment gear 141. The first drive member 142 is used to drive the adjustment gear 141 to move and compress the chain 134 to adjust the tension of the chain 134. This configuration allows for adjustment of the tension of the drive chain 134 of the submerged scraper feeder 1, preventing the coal conveying effect from being affected by the slack of the chain 134.

[0040] In some embodiments, the adjusting assembly 14 further includes a collar 143 and a shaft 144. The collar 143 is movably disposed on the housing 11, and the shaft 144 passes through the collar 143 and is circumferentially rotatable relative to the collar 143. An adjusting gear 141 is sleeved on the shaft 144. This configuration allows the adjusting gear 141 to be movably and rotatably disposed on the housing 11.

[0041] In some embodiments, the adjusting gear 141 meshes with the inner or outer side of the chain 134. In this embodiment, the adjusting gear 141 meshes with the inner side of the chain 134, that is, the adjusting gear 141 can move outward of the chain 134 to cooperate with the first gear 132 and the second gear 133 to tighten the chain 134.

[0042] In some embodiments, the first driving member 142 is a cylinder. For example, in a specific configuration, the cylinder is fixed to the outer wall of the housing 11, and the cylinder's telescopic rod is connected to a collar 143. When the cylinder controls the telescopic rod to retract, the collar 143 drives the adjusting gear 141 to move so that the adjusting gear 141 presses against the chain 134. Of course, the first driving member 142 can also be other types of driving members, such as electric push rods, hydraulic push rods, etc.

[0043] In some embodiments, a groove 113 is provided on the side wall of the housing 11, and the collar 143 and the first driving member 142 are disposed within the groove 113. In a specific configuration, the groove 113 can be arranged in a horizontal direction. This configuration can reduce the influence of the external environment on the adjustment component 14, which is beneficial to ensuring the reliability of the adjustment component 14.

[0044] In some embodiments, the collar 143 can slide with the groove 113. That is, the groove 113 can guide the collar 143. This configuration ensures the stability of the collar 143 during movement and prevents the collar 143 from shifting vertically, thus affecting the adjustment effect.

[0045] In some embodiments, the submerged scraper feeder 1 further includes a striking assembly 15, which is disposed at the feed inlet 111 and / or the discharge outlet 112. The striking assembly 15 is configured to strike the feed inlet 111 and / or the discharge outlet 112. For example, in a specific configuration, striking assemblies 15 can be respectively disposed at the feed inlet 111 and the discharge outlet 112. This configuration enables vibration of the feed inlet 111 and the discharge outlet 112, thereby facilitating coal discharge and preventing blockage of the feed inlet 111 and the discharge outlet 112.

[0046] In some embodiments, the striking assembly 15 includes a drive motor 151 and a striking part 152. The drive motor 151 is disposed in the housing 11, and the striking part 152 is disposed on the drive shaft of the drive motor 151. When the drive motor 151 controls the drive shaft to rotate, it drives the striking part 152 to strike. For example, in a specific configuration, the striking part 152 can be an eccentric wheel, which is fitted outside the drive shaft of the drive motor 151. When the drive motor 151 drives its drive shaft to rotate clockwise or counterclockwise, it can drive the eccentric wheel to strike the feed inlet 111 and the discharge outlet 112. This configuration enables the striking function of the striking assembly 15.

[0047] In some embodiments, the submerged scraper feeder 1 further includes a feed control assembly 16, which includes a feed frame 161 and a blocking mechanism. The feed frame 161 is disposed on the housing 11 and has a coal passage communicating with the feed inlet 111 and the outside. The blocking mechanism is disposed on the housing 11 and is configured to open or close the coal passage. For example, in practical use, the feed control assembly 16 can intermittently close the coal passage, thereby achieving intermittent feeding and reducing the probability of blockage.

[0048] In some embodiments, the blocking mechanism includes a baffle 162 and a second driving member 163. The baffle 162 is movably disposed on the feed frame 161, and the second driving member 163 is disposed on the housing 11 and connected to the baffle 162. The second driving member 163 is used to drive the baffle 162 to move relative to the feed frame 161 to open or close the coal passage. For example, in a specific configuration, the second driving member 163 can drive the baffle 162 to move horizontally to open or close the coal passage. This configuration enables the blocking mechanism to open or close the coal passage.

[0049] In some embodiments, the second driving member 163 is an electric actuator. For example, in a specific configuration, the electric actuator is located on the top of the housing 11, and its telescopic rod is connected to the baffle 162. When the electric actuator controls its telescopic rod to extend, it drives the baffle 162 to close the coal passage; when the electric actuator controls its telescopic rod to retract, it drives the baffle 162 to open the coal passage. Of course, the second driving member 163 can also be other types of driving members, such as a cylinder, a hydraulic actuator, etc.

[0050] In some embodiments, the feed frame 161 is provided with a first opening 1611 and a second opening 1612, which are located on opposite side walls of the feed frame 161. When the coal passage is closed, the opposite ends of the baffle 162 are located within the first opening 1611 and the second opening 1612, respectively. For example, when the coal passage is closed, the baffle 162 sequentially enters the first opening 1611 and the second opening 1612; when the coal passage is opened, the baffle 162 sequentially exits the second opening 1612 and the first opening 1611. Furthermore, the baffle 162 remains within the first opening 1611 during movement, thus providing support for the baffle 162 and preventing it from shifting downwards under its own weight or coal pressure, which would affect the switching function.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this specification should be included within the protection scope of this application.
