Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, and relates to a hopper cleaning device for a coal sampling machine. Background Technology

[0002] A coal sampler is an automatic coal sampling device with automatic sampling function. It mainly consists of a sampling hopper, a screw conveyor, an automatic control device, and a coal sample storage bin. During use, dust and impurities accumulate inside the bin. These impurities affect parameters such as the specific gravity and moisture content of the sampled coal, leading to inaccurate sampling results. Therefore, it is necessary to clean the bin regularly, which requires the use of a cleaning device.

[0003] A material hopper cleaning structure disclosed in Chinese patent CN216103938U includes a hopper body. The hopper body is symmetrically equipped with a cleaning mechanism. The cleaning mechanism includes a fixing rod, and several cleaning sponges are fixedly arranged around the fixing rod.

[0004] When in use, this cleaning structure sprays water through the outlet to clean the hopper body; a rotating motor drives a fixed rod and a sleeve rod to rotate, causing the cleaning sponge to rotate and clean the inner wall of the hopper body. However, the cleaning sponge rotates around the rotation axis of the fixed rod, which is fixed to the inner wall of the hopper body, resulting in a fixed cleaning range for the cleaning sponge and insufficient cleaning effect.

[0005] A feed bin cleaning tool disclosed in Chinese patent CN220049327U uses an adjusting groove and an adjusting rod that are slidably connected. The spring force can push the adjusting rod to slide in the adjusting groove, thereby adjusting the connection length between the fixed rod and the adjusting rod. The adjusting rod further pushes the cleaning brush to fit against the inner wall of the feed bin, controls the drive motor to work, and drives the cleaning brush to rotate by rotating the rod, thereby effectively cleaning the feed adhering to the inner wall of the feed bin.

[0006] This cleaning tool cleans the inner wall of the hopper using a cleaning brush. However, the position of the bristles on one side of the cleaning brush is fixed, and the gaps between the bristles do not come into contact with the inner wall of the hopper during cleaning, resulting in insufficient cleaning effect.

[0007] To address the aforementioned problems, this utility model proposes a hopper cleaning device for a coal sampling machine. Utility Model Content

[0008] To address the problems existing in the background technology, this utility model proposes a hopper cleaning device for a coal sampling machine.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a hopper for a coal sampler, a sealing cover is detachably installed on the top of the hopper, a rotating tube is rotatably passed through the middle of the sealing cover via a bearing, the rotating tube is vertically arranged, and several nozzles are uniformly fixedly installed at the bottom of the rotating tube.

[0010] A connecting plate is fixedly sleeved on the rotating tube. A rotating rod is rotatably passed through both ends of the connecting plate via bearings. The rotating rod is parallel to the rotating tube. Several sponge boards are uniformly fixedly connected to the outer surface of the rotating rod. The other end of the sponge board abuts against the inner wall of the silo.

[0011] A drive assembly is provided on the top of the sealing cover, which drives the rotating tube to rotate. A transmission assembly is provided inside the sealing cover, which drives two rotating rods to rotate when the rotating tube rotates.

[0012] Furthermore, the drive assembly includes a motor, which is fixedly connected to the top of the sealing cover. A first bevel gear is fixedly connected to the output end of the motor, and a second bevel gear is fixedly sleeved on the rotating tube, with the second bevel gear meshing with the first bevel gear.

[0013] Furthermore, a rotary joint is fixedly installed at the top end of the rotating tube, and a water inlet pipe is fixedly installed at the other end of the rotary joint.

[0014] Furthermore, a discharge pipe is fixedly connected to the bottom of the hopper, and a valve is installed on the discharge pipe. A vacuum cleaner is fixedly connected to one side of the hopper, and a through hole is opened on the side of the hopper, which corresponds to the suction port of the vacuum cleaner. A vent pipe is fixedly inserted through the top surface of the sealing cover, and the vent pipe is connected to the inner cavity of the hopper.

[0015] Furthermore, the transmission assembly includes a ring, which is fixedly connected to the inside of the sealing cover. The top surface of the connecting plate slides with the bottom surface of the ring, and several slots are evenly provided on the inner wall of the ring.

[0016] Each of the rotating rods is coaxially fixedly connected to a first turntable at its top end. Several protrusions are uniformly fixedly connected to the outer surface of the first turntable, and the protrusions are movably engaged in the inside of the slot.

[0017] Furthermore, the transmission assembly includes several protruding rods, which are circumferentially distributed and fixedly connected to the top of the inner wall of the sealing cover, and the protruding rods are arranged vertically.

[0018] Each of the rotating rods is coaxially fixedly connected to a second turntable at its top end. Several protrusions are uniformly fixedly connected to the outer surface of the second turntable, and the protrusions are movably arranged between two adjacent protrusions.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The hopper cleaning device of this coal sampler is equipped with two rotating rods, each with several sponge plates fixedly connected to it. When the nozzle sprays water, the drive assembly drives the rotating tube to rotate, causing the nozzle to spray water onto different parts of the hopper's inner wall. Simultaneously, the rotating tube drives the connecting plate to rotate, causing the two rotating rods to rotate around the rotation axis of the rotating tube. The rotating rods drive the first turntable to rotate, causing the protrusion to move into the slot, which in turn causes the first turntable to rotate, and the rotating rods to rotate, allowing the sponge plates to clean different parts of the hopper's inner wall, resulting in a good cleaning effect.

[0029] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: a hopper cleaning device for a coal sampler, including a hopper 1 of the coal sampler, with a sealing cover 3 detachably installed on the top of the hopper 1. The sealing cover 3 is fixed to the top of the hopper 1 by bolts, making it easy to disassemble the sealing cover 3.

[0031] A rotating tube 7 is rotatably inserted through the middle of the sealing cover 3 via a bearing. The rotating tube 7 is vertically arranged. The bearing positions the rotating tube 7 on the sealing cover 3 to facilitate its rotation. Several nozzles 9 are evenly fixedly installed at the bottom of the rotating tube 7. The nozzles 9 are all located below the sealing cover 3 to spray water onto the inner wall of the hopper 1.

[0032] A rotary joint 20 is fixedly installed at the top end of the rotating pipe 7, and a water inlet pipe 8 is fixedly installed at the other end of the rotary joint 20. The rotary joint 20 is a pipe connection device, and the connected pipes can rotate relative to each other, which can be used to convey various media such as gas, liquid, and oil. The rotary joint 20 is existing equipment, so the rotation of the rotating pipe 7 does not affect the water delivery of the water inlet pipe 8. A support frame can be fixed to the top of the sealing cover 3, and the water inlet pipe 8 can be fixed on the support frame to support the water inlet pipe 8.

[0033] A drive assembly is provided on the top of the sealing cover 3, which drives the rotating tube 7 to rotate.

[0034] The drive assembly includes a motor 4, which is fixedly connected to the top of the sealing cover 3. A first bevel gear 5 is fixedly connected to the output end of the motor 4. A second bevel gear 6 is fixedly sleeved on the rotating tube 7, and the second bevel gear 6 meshes with the first bevel gear 5. The motor 4 drives the first bevel gear 5 to rotate, and the first bevel gear 5 drives the second bevel gear 6 to rotate, thereby causing the rotating tube 7 to rotate.

[0035] A connecting plate 10 is fixedly sleeved on the rotating tube 7. A rotating rod 11 is rotatably passed through both ends of the connecting plate 10 via bearings. The bearings support and position the rotating rod 11 so that the rotating rod 11 can rotate on the connecting plate 10.

[0036] The rotating rod 11 is parallel to the rotating tube 7. Several sponge boards 12 are uniformly fixedly connected to the outer surface of the rotating rod 11, with the other end of each sponge board 12 abutting against the inner wall of the hopper 1. This allows the sponge boards 12 to clean the inner wall of the hopper 1. The sponge boards 12 located on the rotating rod 11 are at different heights.

[0037] A discharge pipe 16 is fixedly connected to the bottom of the hopper 1, and a valve is installed on the discharge pipe 16. The water used for cleaning in the hopper 1 is discharged through the discharge pipe 16. A vacuum cleaner 2 is fixedly connected to one side of the hopper 1. A through hole is opened on the side of the hopper 1, corresponding to the suction port of the vacuum cleaner 2. The suction port of the vacuum cleaner 2 sucks away solid impurities from the hopper 1 through the through hole. A vent pipe is fixedly inserted through the top surface of the sealing cover 3, and the vent pipe communicates with the inner cavity of the hopper 1. After the sealing cover 3 is fixed to the top of the hopper 1, air is vented into the hopper 1 through the vent pipe.

[0038] The sealing cover 3 has a transmission assembly inside. When the rotating tube 7 rotates, the transmission assembly drives the two rotating rods 11 to rotate. When the rotating tube 7 rotates, it will drive the connecting plate 10 and the rotating rods 11 to rotate around the rotation axis of the rotating tube 7.

[0039] The transmission assembly includes a ring 14, which is fixedly connected to the inside of the sealing cover 3. The top surface of the connecting plate 10 slides against the bottom surface of the ring 14, allowing the connecting plate 10 to rotate at the bottom of the ring 14. Several slots 15 are evenly distributed on the inner wall of the ring 14.

[0040] Each rotating rod 11 has a first turntable 13 coaxially fixedly connected to its top end. Several protrusions 19 are evenly fixedly connected to the outer surface of the first turntable 13. The protrusions 19 are movably engaged inside the slots 15. The first turntable 13 can be rotated through the cooperation of the slots 15 and the protrusions 19.

[0041] Working principle:

[0042] In use, the sealing cover 3 is fixed to the top of the hopper 1 with bolts, and the vent pipe connects the hopper 1 to the outside air. The nozzle 9 and the rotating rod 11 are both located inside the hopper 1. The water inlet pipe 8 is fixed above the sealing cover 3 using a support frame, and one end of the water inlet pipe 8 is connected to the water source.

[0043] Start motor 4, which drives the first bevel gear 5 to rotate. The first bevel gear 5 drives the second bevel gear 6 to rotate, causing the rotating tube 7 to rotate, which in turn drives the nozzle 9 to rotate inside the hopper 1.

[0044] The rotating tube 7 drives the connecting plate 10 to rotate, causing the two rotating rods 11 to rotate around the rotation axis of the rotating tube 7. The rotating rods 11 drive the sponge plate 12 and the first turntable 13 to rotate around the rotation axis of the rotating tube 7.

[0045] The protrusions 19 on the first turntable 13 will rotate sequentially into the slots 15. The cooperation between the protrusions 19 and the slots 15 causes the first turntable 13 to rotate. The first turntable 13 drives the rotating rod 11 to rotate, causing the sponge board 12 to rotate around the rotation axis of the corresponding rotating rod 11. This causes the sponge board 12 to rotate to different parts of the inner wall of the hopper 1, cleaning the inner wall of the hopper 1.

[0046] Turning on the vacuum cleaner 2 will suck away the impurities cleaned by the sponge board 12.

[0047] After vacuuming is complete, water is introduced into the water inlet pipe 8, and the water enters the rotating pipe 7. Then, the water is sprayed onto the inner wall of the hopper 1 through the nozzle 9. At the same time, the sponge board 12 also cleans the inner wall of the hopper 1, scrubbing it.

[0048] During the washing process, open the valve on the discharge pipe 16 to allow the water after washing to be discharged through the discharge pipe 16.

[0049] Example 2: Figures 4-5 As shown, the difference between this embodiment and embodiment 1 is that the transmission component includes several protruding rods 18, which are circumferentially distributed and fixedly connected to the top of the inner wall of the sealing cover 3, and the protruding rods 18 are arranged vertically.

[0050] Each rotating rod 11 has a second turntable 17 coaxially fixedly connected to its top end. Several protrusions 19 are uniformly fixedly connected to the outer surface of the second turntable 17. The protrusions 19 are movably arranged between two adjacent protrusions 18. The protrusions 18 limit the movement of the protrusions 19 to facilitate the rotation of the second turntable 17 inside the sealing cover 3.

[0051] Working principle:

[0052] Start motor 4, which drives the first bevel gear 5 to rotate. The first bevel gear 5 drives the second bevel gear 6 to rotate, causing the rotating tube 7 to rotate, which in turn drives the nozzle 9 to rotate inside the hopper 1.

[0053] The rotating tube 7 drives the connecting plate 10 to rotate, causing the two rotating rods 11 to rotate around the rotation axis of the rotating tube 7. The rotating rods 11 drive the sponge plate 12 and the second turntable 17 to rotate around the rotation axis of the rotating tube 7.

[0054] The protrusions 19 on the second turntable 17 will move sequentially between two adjacent protrusions 18. Through the cooperation of the protrusions 19 and the protrusions 18, the second turntable 17 will rotate. The second turntable 17 will drive the rotating rod 11 to rotate, causing the sponge plate 12 to rotate around the rotation axis of the corresponding rotating rod 11. This will cause the sponge plate 12 to rotate to different parts of the inner wall of the hopper 1, cleaning the inner wall of the hopper 1.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
