The shell 11 has an inner cavity and a feed port 111 and a discharge port 112 connected to the inner cavity. The conveying assembly 12 is arranged in the inner cavity and located between the feed port 111 and the discharge port 112, and is used to transport coal from the feed port 111 to the discharge port 112. The driving assembly 13 includes a motor 131 and a chain transmission mechanism, the motor 131 is arranged in the shell 11, the chain transmission mechanism is connected between the motor 131 and the driving roller shaft 121 of the conveying assembly 12, and the chain transmission mechanism is driven when the motor 131 is started to make the conveying assembly 12 run.

[0042] In some embodiments, the conveying assembly 12 includes a driving roller 121, a conveyor belt 122, and a scraper 123. The driving roller 121 is rotatably disposed on the housing 11. The conveyor belt 122 is sleeved outside the driving roller 121 and can run when the driving roller 121 rotates. The scraper 123 is disposed outside the conveyor belt 122 and can push the coal to form a coal layer flow when the conveyor belt 122 runs, so that the coal flows continuously from the coal inlet to the discharge port 112.

[0043] In some embodiments, the chain transmission mechanism includes a first gear 132, a second gear 133 and a chain 134. The first gear 132 is disposed on the driving shaft of the motor 131, the second gear 133 is disposed on the driving 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 is started, the driving 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 through the chain 134, and the second gear 133 drives the driving roller shaft 121 of the conveying assembly 12 to rotate when rotating circumferentially, thereby making the conveyor belt 122 run.

[0044] In some embodiments, the driving assembly 13 is disposed on the outer wall of the housing 11. For example, in a specific configuration, one end of a driving roller 121 of the transmission assembly 12 is passed through the outer wall of the housing 11, so that the driving assembly 13 located on the outer wall of the housing 11 can be connected to the driving roller 121 and drive the driving roller 121 to rotate.

The first drive member 142 is used to drive the adjustment gear 141 to move to squeeze the chain 134 to adjust the tightness of the chain 134. In this way, the tightness of the transmission chain 134 of the scraper coal feeder 1 can be adjusted to avoid affecting the conveying effect of coal due to the looseness of the chain 134.

[0046] In some embodiments, the adjustment assembly 14 further includes a collar 143 and a shaft 144, the collar 143 is movably disposed on the housing 11, the shaft 144 is inserted through the collar 143 and can rotate circumferentially relative to the collar 143, and the adjustment gear 141 is sleeved on the shaft 144. In this way, the adjustment gear 141 can be movably and rotatably disposed on the housing 11.

[0047] In some embodiments, the adjusting gear 141 is meshed with the inner side or the outer side of the chain 134. In this embodiment, the adjusting gear 141 is meshed with the inner side of the chain 134, that is, the adjusting gear 141 can move toward the outer side of the chain 134 to cooperate with the first gear 132 and the second gear 133 to tighten the chain 134.

[0048] 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 telescopic rod of the cylinder is connected to the collar 143. When the cylinder controls the telescopic rod to contract, the collar 143 drives the adjusting gear 141 to move forward so that the adjusting gear 141 squeezes the chain 134. Of course, the first driving member 142 can also be other types of driving members, such as an electric push rod, a hydraulic push rod, etc.

[0049] 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 provided in the groove 113. In a specific configuration, the groove 113 can be provided in a horizontal direction. This configuration can reduce the influence of the external environment on the adjustment component 14, which is conducive to ensuring the reliability of the adjustment component 14.

[0050] In some embodiments, the collar 143 can be slidably matched with the groove 113. That is, the groove 113 can guide the collar 143. This arrangement can ensure the stability of the collar 143 when moving, and prevent the collar 143 from deviating up and down, which affects the adjustment effect.

[0051] In some embodiments, the scraper coal feeder 1 further includes a knocking assembly 15, which is arranged at the feed port 111 and / or the discharge port 112, and the knocking assembly 15 is arranged to knock the feed port 111 and / or the discharge port 112. For example, in a specific setting, the feed port 111 and the discharge port 112 can be respectively provided with a knocking assembly 15. Such a setting can realize vibration of the feed port 111 and the discharge port 112, thereby facilitating the discharge of coal and avoiding blockage of the feed port 111 and the discharge port 112.

[0052] In some embodiments, the knocking assembly 15 includes a driving motor 151 and a knocking part 152. The driving motor 151 is arranged on the housing 11, and the knocking part 152 is arranged on the driving shaft of the driving motor 151. When the driving shaft of the driving motor 151 controller rotates, the knocking part 152 is driven to knock. For example, in a specific setting, the knocking part 152 can be an eccentric wheel, and the eccentric wheel is mounted outside the driving shaft of the driving motor 151. When the driving motor 151 drives its driving shaft to rotate clockwise or counterclockwise, it can drive the eccentric wheel to knock the feed port 111 and the discharge port 112. This setting can realize the knocking function of the knocking assembly 15.

[0053] In some embodiments, the scraper coal feeder 1 further includes a feed control assembly 16, which includes a feed frame 161 and a shielding mechanism. The feed frame 161 is disposed on the housing 11 and has a coal passage connecting the feed port 111 and the outside, and the shielding mechanism is disposed on the housing 11, and the shielding mechanism is configured to open or close the coal passage. For example, in specific use, the feed control assembly 16 can intermittently close the coal passage, so that intermittent feeding can be achieved, which is conducive to reducing the probability of blockage.

[0054] In some embodiments, the shielding mechanism includes a baffle 162 and a second driving member 163, the baffle 162 is movably disposed on the feed frame 161, the second driving member 163 is disposed on the housing 11 and connected to the baffle 162, and 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 channel. For example, in a specific setting, the second driving member 163 can drive the baffle 162 to move horizontally to open or close the coal channel. This setting can realize the function of the shielding mechanism to open or close the coal channel.

[0055] In some embodiments, the second driving member 163 is an electric push rod. For example, in a specific configuration, the electric push rod is disposed at the top of the housing 11, and the telescopic rod of the electric push rod is connected to the baffle 162. When the electric push rod controls the telescopic rod to extend, the baffle 162 is driven to close the coal channel, and when the electric push rod controls the telescopic rod to retract, the baffle 162 is driven to open the coal channel. Of course, the second driving member 163 can also be other types of driving members, such as a cylinder, a hydraulic push rod, etc.

[0056] In some embodiments, the feed frame 161 is provided with a first opening 1611 and a second opening 1612, and the first opening 1611 and the second opening 1612 are respectively located on opposite side walls of the feed frame 161. When the coal passage is closed, the opposite ends of the baffle 162 are respectively located in the first opening 1611 and the second opening 1612. For example, when the coal passage is closed, the baffle 162 sequentially penetrates the first opening 1611 and the second opening 1612, and when the coal passage is opened, the baffle 162 sequentially exits the second opening 1612 and the first opening 1611. Furthermore, the baffle 162 is always located in the first opening 1611 when moving, so that the baffle 162 can be supported and prevented from moving downward under its own gravity or coal pressure, thereby affecting the switch function.
