[0032] Rack 2 is used to be inclined and placed above water sump water ditch 1.

[0033] A pair of chain wheel drive mechanism is symmetrically arranged on rack 2, and chain wheel drive mechanism includes driving sprocket 3 located at the bottom of rack 2, driven sprocket 4 located at the top of rack 2 and transmission chain 5 connected between the two.

[0034] Harrow tooth mounting plate 6 is arranged between a pair of transmission chains 5, and a row of harrow teeth 7 is arranged on harrow tooth mounting plate 6.

[0035] Drive mechanism is connected to a pair of driving sprocket 3, for driving transmission chain 5 located at the lower side of rack 2 to rotate towards the direction opposite to the water flow of water sump water ditch 1, to drive harrow tooth 7 to rotate through water sump water ditch 1 to salvage garbage sundry in it.

[0036] Storage sundry box 12 is located below the top of rack 2, and cleaning mechanism 13 is arranged above storage sundry box 12, for washing garbage sundry of harrow tooth 7 into storage sundry box 12.

[0037] It should be noted that the rack 2 can adopt a frame structure with strong bearing capacity. The top of the rack 2 is inclined towards the water inlet, that is, the top and the bottom of the rack 2 are arranged from near to far according to the distance from the water inlet, a pair of driven sprockets 4 are symmetrically arranged on the top of the rack 2, a pair of driving sprockets 3 are symmetrically arranged on the bottom of the rack 2, the spacing between the pair of driven sprockets 4 and the pair of driving sprockets 3 is approximately the width between the two sides of the frame of the rack 2, and a transmission chain 5 is connected between each pair of driven sprockets 4 and driving sprockets 3.

[0038] The number of the rake mounting plates 6 is not limited, at least one rake mounting plate 6 is connected between the pair of transmission chains 5 to follow the rotation of the transmission chains 5, and a row of rakes 7 is arranged on the rake mounting plate 6, the row of rakes 7 is composed of a plurality of spaced rakes 7, wherein the number of the rakes 7 and the spacing between adjacent rakes 7 can be set according to the width of the water inlet ditch 1, preferably, the width of the row of rakes 7 is slightly smaller than the width of the water inlet ditch 1, so as to better fish the garbage in the water inlet ditch 1.

[0039] The specific structure of the driving mechanism is not limited, and a motor, a cylinder, an air cylinder or other drivers can be selected, as long as the driving end is connected to the pair of driving sprockets 3 and drives the two to rotate synchronously. As shown in Figure 1 Since the water flow direction A of the water inlet ditch 1 is flowing towards the water inlet, that is, flowing forward, and the top of the rack 2 is inclined towards the water inlet, the driving mechanism needs to drive the driving sprockets 3 to rotate counterclockwise to drive the transmission chains 5 to rotate counterclockwise, so that the transmission chain 5 on the upper side of the rack 2 rotates forward and the transmission chain on the lower side of the rack 2 rotates backward. In this way, after the row of rakes 7 is rotated to the lower side of the rack 2 and immersed in the water inlet ditch 1, it can continue to rotate backward with the transmission chain 5 to move reversely in the water inlet ditch 1, so that the garbage in the water flow is more easily hung on the rakes 7, thereby facilitating the row of rakes 7 to quickly fish the garbage.

[0040] The above structure is adopted in the present application, in use, the row of rakes 7 can rotate counterclockwise to the lower side of the rack 2 with the transmission chain 5, then sink into the water inlet ditch 1 and rotate backward with the transmission chain 5 to the bottom of the rack 2, continue to rotate counterclockwise with the transmission chain 5 to the upper side of the rack 2 to fish out the garbage from the water inlet ditch 1, the row of rakes 7 carrying the garbage continues to rotate forward with the transmission chain 5 to the top of the rack 2, and then uses the cleaning mechanism 13 to flush the garbage on the row of rakes 7 into the garbage storage box 12, and then the inspector cleans it uniformly. Therefore, the present application realizes automatic fishing of garbage in the water inlet of the coal mine water tank, reduces the labor input and labor intensity, and improves the fishing efficiency.

[0041] Preferably, please refer to Figure 1The upper side of the rack 2 is provided with a tensioning device 16, which includes a tensioning wheel abutting against the transmission chain 5 and an adjusting rod connected with the tensioning wheel, the adjusting rod being used to push the tensioning wheel to move towards the transmission chain 5 to adjust the tightness of the transmission chain 5.

[0042] In view of the specific installation mode of the rake mounting plate 6, on the basis of the above embodiment, please refer to Figure 1 A plurality of rake mounting plates 6 are arranged at equal intervals around one turn of the transmission chain 5, and each rake mounting plate 6 is arranged with a row of rakes 7 at equal intervals along the length direction of the rake mounting plate 6.

[0043] It can be understood that one turn of the transmission chain 5 is one salvage operation, and the plurality of rake mounting plates 6 are arranged at equal intervals around one turn of the transmission chain 5, so that the number of the row of rakes 7 immersed in the water channel 1 during one salvage operation is increased, thereby greatly improving the salvage efficiency.

[0044] Further, the plurality of rakes 7 in the row of rakes 7 are arranged at equal intervals along the length direction of the rake mounting plate 6, which can increase the density of the row of rakes 7, and is beneficial to avoid that the garbage and sundries are retained in the water channel 1 through the gap between adjacent rakes 7.

[0045] Optionally, please refer to Figure 2 The two sides of the rake mounting plate 6 are detachably arranged on the side surface of the chain link of the transmission chain 5 through the L-shaped plate 8, so as to facilitate the disassembly and adjustment of the rake mounting plate 6.

[0046] In view of the specific structure of the rake 7, on the basis of the above embodiment, the rake 7 is a hook-shaped rake 7, which includes an elongated body 71 and a hook head 72, one end of the elongated body 71 is connected with the rake mounting plate 6, the other end of the elongated body 71 is connected with the hook head 72, and the hook head 72 is arranged obliquely towards the transmission direction of the transmission chain 5.

[0047] Specifically, the rake 7 is formed by connecting the elongated body 71 and the hook head 72 to form a hook-shaped rake 7, the rake mounting plate 6 is provided with a insertion hole 61, as shown in Figure 1 and Figure 3 One end of the elongated body 71 is inserted into the insertion hole 61, the other end of the elongated body 71 extends a certain length away from the rake mounting plate 6 and is connected with the hook head 72, which is beneficial to increase the depth of the rake 7 immersed in the water channel 1, so as to avoid the generation of a salvage dead zone, thereby reducing the deposition amount of garbage and sundries in the water channel 1, and further improving the salvage effect.

[0048] In addition, as shown in Figure 1As shown, the hook head 72 is obliquely arranged towards the transmission direction of the transmission chain 5, that is, the tines 7 located at the lower side of the frame 2 are all rearwardly inclined, i.e. inclined away from the water tank opening, so that the tines 7 immersed in the water ditch 1 of the water tank opening can better block the garbage from flowing forward with the water flow, thereby further improving the fishing effect. The tines 7 located at the upper side of the frame 2 are all forwardly inclined, i.e. inclined towards the water tank opening, so as to avoid the garbage from falling off the tines 7 due to the influence of gravity.

[0049] To further optimize the fishing effect of the present application, on the basis of the above embodiments, please refer to Figure 1 , the frame 2 is provided with a grid plate 14 for blocking the garbage carried by the tines 7 rotated from the lower side to the upper side of the frame 2 from falling back into the water ditch 1 of the water tank opening.

[0050] Specifically, the grid plate 14 is arranged between the two side frames of the frame 2 and located between the upper chain and the lower chain of a circle of the transmission chain 5, so as to prevent the garbage carried by the tines 7 of the transmission chain 5, i.e. the upper chain of the transmission chain 5, located at the upper side of the frame 2 from falling into the water ditch 1 of the water tank opening, thereby further improving the fishing effect.

[0051] Considering the specific installation position and structure of the garbage storage box 12, on the basis of the above embodiments, the inside of the garbage storage box 12 is provided with a sieve plate, and the bottom end of the garbage storage box 12 is provided with a water leakage hole in communication with the water ditch 1 of the water tank opening. As can be seen, the sieve plate is arranged in the inside of the garbage storage box 12, so as to filter out the mine water contained in the garbage falling into the inside of the garbage storage box 12, and the mine water flows into the water ditch 1 of the water tank opening through the water leakage hole, so as to reduce the amount of mine water contained in the fished garbage, thereby reducing the influence on the storage or collection operation of the mine water.

[0052] Preferably, the garbage storage box 12 is located above the water ditch 1 of the water tank opening, i.e. the water leakage hole is located above the water ditch 1 of the water tank opening, and a pipeline is not required to be arranged between the water leakage hole and the water ditch 1 of the water tank opening, so as to enable the mine water to fall into the water ditch 1 of the water tank opening, thereby saving the pipeline and reducing the cost.

[0053] Preferably, the garbage storage box 12 is arranged at the top end of the moving frame, the bottom end of the moving frame is arranged at one side of the water ditch 1 of the water tank opening, and the moving frame is connected with a mover for driving the moving frame to reciprocatingly approach or move away from the water ditch 1 of the water tank opening. In this way, the inspector can realize the moving out or moving in of the garbage storage box 12 by controlling the mover, thereby saving the manpower for carrying the garbage storage box 12 and facilitating the cleaning of the garbage storage box 12.

[0054] Considering the specific installation position and structure of the cleaning mechanism 13, on the basis of the above embodiments, the cleaning mechanism 13 is a nozzle mechanism, the nozzle mechanism is arranged on the frame 2 and located below the driven sprocket 4, the water inlet end of the nozzle mechanism is used for connecting a water supply device, and the water outlet end of the nozzle mechanism is arranged towards the garbage storage box 12.

[0055] It can be understood that after the row of tines 7 passes through the driven sprocket 4 and is placed under the frame 2, part of the garbage on the row of tines 7 is automatically dropped into the garbage storage box 12 under the action of gravity. Thus, the nozzle mechanism is located below the driven sprocket 4, and the remaining garbage on the row of tines 7 falls into the garbage storage box 12 under the flushing action of the nozzle mechanism, which not only improves the flushing effect on the row of tines 7, but also saves a certain amount of water.

[0056] Optionally, the nozzle mechanism includes a plurality of nozzles, which are arranged on the frame 2 along the length direction of the tine mounting plate 6 at equal intervals, so as to better improve the flushing effect on the row of tines 7.

[0057] Considering the specific structure of the driving mechanism, on the basis of the above embodiments, please refer to Figure 1 The driving mechanism includes a driver, a pair of driving sprockets, and a pair of driving chains 11. The pair of driving sprockets are sleeved on the driving shaft of the driver and are respectively connected in transmission with the pair of driving chains 11 and the pair of driving sprockets.

[0058] It can be understood that the driving mechanism is installed above the water tank mouth ditch 1, and its working environment is humid. Therefore, the driving mechanism adopts a transmission chain structure suitable for a humid environment to drive the driving sprocket 3 to rotate, so as to ensure the normal rotation of the driving sprocket 3 and the reliable operation of the device.

[0059] It should be noted that the coal mine usually uses a mine air compressor to provide compressed air to the inside of the mine, so as to realize ventilation and air exchange in the mine, ensure the freshness of the air for the miners, and dilute and remove harmful gases in the mine. The safety of the mine air compressor is high.

[0060] Further, please refer to Figure 1 The driver includes a pneumatic motor 9 and a speed reducer 10. The air inlet of the pneumatic motor 9 is connected with the mine air compressor, the output shaft is connected with the speed reducer 10, and the output shaft of the speed reducer 10 is connected with the pair of driving sprockets. The driver with this structure has the advantages of low operating cost, high safety, and high torque output. On the other hand, the mine air compressor can be used as a power source, which can reasonably avoid the problem of device explosion, and the overall device has the advantages of high reliability and corrosion resistance.

[0061] It should be noted that the mine air compressor contains impurities such as water and oil. The impurities entering the pneumatic motor 9 will reduce the performance and service life of the pneumatic motor 9, and thus reduce the reliability of the normal operation of the device.

[0062] In order to improve the reliability of normal operation of the application, on the basis of the above embodiment, the application further comprises a pneumatic control box, the pneumatic control box comprises a box body for storing mine compressed air and an air inlet pipe connected with the air inlet of the pneumatic motor 9, and a switch valve and an oil-water separator are arranged on the air inlet pipe. In this way, when the driving device needs to be operated, the switch valve is opened, the mine compressed air in the box body enters the oil-water separator through the air inlet pipe first, the oil-water separator separates the condensed water, oil and other impurities in the mine compressed air, and the purified mine compressed air is injected into the pneumatic motor 9 through the air inlet pipe, so that the performance and service life of the pneumatic motor 9 can be improved, and the purpose of improving the reliability of normal operation of the application is achieved.
