Description

Technical Field

[0001] The invention relates to the technical field of casting, and in particular to an automatic cleaning device for a vertical mill box, which is a mining machinery accessory. Background Art

[0002] Tubular components produced by sand casting typically have molding sand inside. Methods for removing the sand include water blasting, mechanical vibration, hammering, and steel chisel removal. However, even after removal, sand particles often remain inside the tube, making manual removal cumbersome and inefficient.

[0003] At present, the vertical mill housings of mining machinery accessories are all made by casting. However, due to their large size, heavy weight and complex structure, manual cleaning of the molding sand is quite time-consuming and labor-intensive. In addition, the bottom of the mill is divided into multiple fan-shaped spaces by annular layers and multiple ribs, which makes actual cleaning more difficult and the cleaning of the molding sand is even more incomplete. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic cleaning device for a vertical mill housing of a mining machinery accessory to solve the above-mentioned defects caused by the prior art.

[0005] An automatic cleaning device for a vertical mill housing of a mining machinery accessory includes a swing mechanism and a cleaning mechanism, wherein:

[0006] The swing mechanism includes a connecting pipe, a transition pipe, a swing pipe and a motor. The transition pipe is vertically and coaxially welded to the bottom of the connecting pipe. The swing pipe is provided with a plurality of swing pipes and is evenly hinged to the lower end of the transition pipe. The motor is provided with a plurality of motors and is evenly distributed around the connecting pipe. The motor is vertically downwardly mounted on the lower end of the connecting pipe through a fixing plate. The output end of the motor is keyed to a crankshaft. The swing pipe is provided with a sliding groove that is slidably connected to the connecting rod shaft diameter of the crankshaft.

[0007] The cleaning mechanism is provided with several and is distributed correspondingly under each swinging tube. The cleaning mechanism includes a mounting tube and a cleaning tube. A pair of hinged bars are connected in parallel between the mounting tube and the swinging tube. The cleaning tube is provided with a pair of and is rotatably connected to the outer end of the mounting tube. The cleaning tube is provided with an L-shaped structure and water spray outlets are evenly distributed on its side.

[0008] Preferably, the connecting pipe is screwed to the end of the robotic arm, and a sealing gasket is installed between the two. The side of the connecting pipe is symmetrically provided with water inlets, and the water inlets are connected to the external booster pump. The lower end of the transition pipe is coaxially connected to the water divider, and water diversion ports are evenly distributed around the water divider. The inner end of the mounting pipe is centrally provided with an inlet, and a water pipe is connected between the inlet and the water diversion port. The outer end of the mounting pipe is symmetrically provided with a pair of outlets, and the cleaning pipe is correspondingly rotatably connected to the outlet.

[0009] Preferably, a gear is coaxially fixed to one end of the cleaning tube near the outlet, a U-shaped connecting piece is provided below each pair of gears, and a pair of racks are symmetrically connected to the inner side of the connecting piece, and the racks and gears on the same side are meshed with each other, and the outer end of the cleaning tube is integrally connected to a connecting ear, and a reset spring is connected between the connecting ear and the connecting piece.

[0010] Preferably, a collecting pipe is integrally connected to the lower side of the mounting pipe, and a collecting port is coaxially provided at the inner end of the collecting pipe, the collecting port is connected to an external water pump, and two rows of collecting troughs are symmetrically provided on the left and right sides of the collecting pipe.

[0011] Preferably, the collecting pipe is integrally connected with an arc-shaped water-shoveling plate below the collecting troughs on both sides.

[0012] Preferably, both ends of the water-shoveling plate are vertically connected with connecting pieces, and a water retaining bar is rotatably connected between the connecting pieces on both sides, and the water retaining bar is horizontally abutted against the collecting trough through a C-shaped elastic bar.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. When the robotic arm drives the automatic cleaning device to the bottom of the vertical mill, the connecting parts will be squeezed by the bottom of the box and move upward. After the transmission of the gear and rack, the cleaning pipes on both sides are driven to gradually adjust from a horizontal state to a vertical state, so that the cleaning pipes and collection pipes can be deeply inserted into the fan-shaped spaces at the bottom of the vertical mill.

[0015] 2. The booster pump sequentially pumps water into the connecting pipe, transition pipe, water distributor, water guide pipe, installation pipe, and cleaning pipe. Finally, high-pressure water is ejected from the nozzle on the cleaning pipe to flush and clean the various fan-shaped spaces at the bottom of the vertical mill housing. At the same time, the motor drives the swing pipe to swing back and forth through the crankshaft, which in turn drives the installation pipe, cleaning pipe, and collection pipe in the cleaning mechanism to swing back and forth.

[0016] 3. When high-pressure water is ejected from the nozzles on the cleaning pipe, the pump creates negative pressure in the collection trough on the collection pipe, allowing the cleaned dirty water and molding sand to be drawn and collected through the collection trough. The shovel blade shovels the dirty water and molding sand into the collection trough, further facilitating their thorough collection. A movable water retaining bar blocks the collection trough on the side not facing the water, preventing dirty water and molding sand from escaping from this side of the collection pipe.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] like Figures 1 to 9 As shown, an automatic cleaning device for a vertical mill housing of a mining machinery accessory includes a swing mechanism 10 and a cleaning mechanism 20, wherein:

[0031] The swing mechanism 10 includes a connecting pipe 101, a transition pipe 103, a swing pipe 106 and a motor 107. The transition pipe 103 is vertically coaxially welded to the bottom of the connecting pipe 101. The swing pipe 106 is provided with several and is evenly hinged to the lower end of the transition pipe 103. The motor 107 is provided with several and is evenly distributed around the connecting pipe 101. The motor 107 is vertically downwardly installed on the lower end of the connecting pipe 101 through a fixed plate 108. The output end of the motor 107 is keyed to a crankshaft 109. The swing pipe 106 is provided with a sliding groove 106a that is slidably connected to the connecting rod shaft diameter of the crankshaft 109; the motor 107 drives the swing pipe 106 to swing back and forth through the crankshaft 109, thereby driving the mounting pipe 201 and the cleaning pipe 202 in the cleaning mechanism 20 to swing back and forth.

[0032] The cleaning mechanisms 20 are provided in a plurality and are correspondingly distributed below each oscillating tube 106. The cleaning mechanisms 20 include a mounting tube 201 and a cleaning tube 202. A pair of hinge bars 110 are connected parallel to the mounting tube 201 and the oscillating tube 106. The cleaning tubes 202 are provided with a pair of outer ends that are rotatably connected to the mounting tubes 201. The cleaning tubes 202 have an L-shaped structure and are evenly distributed with water spray ports 202a on their sides. High-pressure water is sprayed through the water spray ports 202a on the cleaning tubes 202, and the high-pressure water is used to flush and clean the various fan-shaped spaces at the bottom of the vertical mill housing 30.

[0033] In this embodiment, the connecting pipe 101 is screwed to the end of the robotic arm, and a sealing gasket 102 is installed between the two. The side of the connecting pipe 101 is symmetrically provided with a water inlet 101a, and the water inlet 101a is connected to the external booster pump. The lower end of the transition pipe 103 is coaxially connected to the water divider 104, and water diversion ports are evenly distributed around the water divider 104. The inner end of the installation pipe 201 is centrally provided with an inlet 201a, and a water pipe 105 is connected between the inlet 201a and the water diversion port. The outer end of the installation pipe 201 is symmetrically provided with a pair of outlets 201b, and the cleaning pipe 202 is correspondingly rotatably connected to the outlet 201b. The automatic cleaning device is driven by a robotic arm to penetrate into the bottom of the vertical mill housing 30. Then, the booster pump sequentially pumps water into the connecting pipe 101, the transition pipe 103, the water distributor 104, the water guide pipe 105, the installation pipe 201 and the cleaning pipe 202. Finally, high-pressure water is ejected through the water nozzle 202a on the cleaning pipe 202, and the high-pressure water is used to flush and clean the fan-shaped spaces at the bottom of the vertical mill housing 30.

[0034] In this embodiment, a gear 203 is coaxially fixed to one end of the cleaning tube 202 near the outlet 201b. A U-shaped connector 205 is provided below each pair of gears 203. A pair of racks 204 are symmetrically connected to the inner side of the connector 205. The racks 204 and the gears 203 on the same side are meshed. A connecting ear 206 is integrally connected to the outer end of the cleaning tube 202, and a return spring 207 is connected between the connecting ear 206 and the connector 205. When the robotic arm drives the automatic cleaning device to penetrate into the bottom of the vertical mill housing 30, the connector 205 is squeezed by the bottom of the housing and moves upward. After transmission by the gear 203 and the rack 204, the cleaning tubes 202 on both sides are gradually adjusted from a horizontal state to a vertical state, thereby allowing the cleaning tubes 202 to penetrate into the various fan-shaped spaces at the bottom of the vertical mill housing 30.

[0035] In this embodiment, a collection pipe 208 is integrally connected to the underside of the mounting pipe 201. A collection port 201a is coaxially disposed at the inner end of the collection pipe 208. This port 201a is connected to an external water pump. Two rows of collection troughs 208b are symmetrically disposed on the left and right sides of the collection pipe 208. When the water outlet 202a on the cleaning pipe 202 sprays high-pressure water, the water pump creates a negative pressure in the collection troughs 208b on the collection pipe 208, allowing the cleaned dirty water and molding sand to be sucked and collected through the collection troughs 208b.

[0036] In this embodiment, the collection pipe 208 is integrally connected to an arc-shaped water shoveling plate 209 below the collection troughs 208b on both sides. When collecting dirty water, the water shoveling plate 209 shovels the dirty water and molding sand into the collection troughs 208b, which helps to collect the dirty water and molding sand more thoroughly.

[0037] In this embodiment, connecting pieces 210 are vertically connected to both ends of the water-shoveling plate 209. A water retaining bar 211 is rotatably connected between the connecting pieces 210 on both sides. The water retaining bar 211 is horizontally abutted against the collection trough 208b via a C-shaped elastic bar 212. When collecting dirty water, the movable water retaining bar 211 can block the collection trough 208b on the non-water-facing side, preventing dirty water and molding sand from entering the collection pipe 208 from escaping from this side.

[0038] The working principle of this mining machinery accessories vertical mill box automatic cleaning device:

[0039] When the robotic arm drives the automatic cleaning device to penetrate into the bottom of the vertical mill housing 30, the connecting piece 205 will be squeezed by the bottom of the housing and move upward, and then after being driven by the gear 203 and the rack 204, the cleaning pipes 202 on both sides are driven to gradually adjust from a horizontal state to a vertical state, so that the cleaning pipes 202 and the collection pipes 208 are penetrated into the various fan-shaped spaces at the bottom of the vertical mill housing 30.

[0040] The booster pump sequentially pumps water into the connecting pipe 101, transition pipe 103, water distributor 104, water guide pipe 105, installation pipe 201, and cleaning pipe 202. Finally, high-pressure water is ejected through the water spray port 202a on the cleaning pipe 202 to flush and clean the various fan-shaped spaces at the bottom of the vertical mill housing 30. Simultaneously, the motor 107 drives the oscillating pipe 106 to oscillate back and forth via the crankshaft 109, thereby driving the installation pipe 201, cleaning pipe 202, and collection pipe 208 in the cleaning mechanism 20 to oscillate back and forth.

[0041] When high-pressure water is ejected from the water outlet 202a of the cleaning pipe 202, a water pump creates negative pressure at the collection trough 208b of the collection pipe 208, allowing the cleaned dirty water and molding sand to be drawn and collected through the collection trough 208b. The dirty water and molding sand are shoveled into the collection trough 208b by the shovel plate 209, further facilitating their thorough collection. A movable water retaining bar 211 blocks the side of the collection trough 208b that is not facing the water, preventing any dirty water and molding sand that enters the collection pipe 208 from escaping from this side.

[0042] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
