Description

Technical Field

[0001] This utility model relates to the field of reciprocating coal feeder technology, and in particular to an anti-jamming and diversion device for a reciprocating coal feeder. Background Technology

[0002] A reciprocating coal feeder is a bulk material conveying device used in mines, coal preparation plants, and other similar locations. It is primarily used to evenly transfer loose materials such as coal into transport or screening equipment. Its core working principle involves a crank-connecting rod mechanism driving an inclined bottom plate in a linear reciprocating motion, utilizing inertia and friction to unload material from storage bins or pits.

[0003] Conventional reciprocating coal feeders lack corresponding screening structures, allowing large particles or impurities, such as stones and metal blocks, to enter. When these particles exceed the feeder's design clearance, they can become stuck between moving parts, creating a rigid obstruction and causing material jamming. Therefore, effectively preventing large particles or impurities from causing material jamming in reciprocating coal feeders is a crucial issue that needs to be addressed in the design of anti-jamming and diversion devices for these feeders. Utility Model Content

[0004] This invention provides an anti-jamming and diversion device for reciprocating coal feeders to solve the problem of material jamming caused by large particles or impurities.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions: This utility model provides an anti-jamming and diversion device for a reciprocating coal feeder, including a reciprocating coal feeder and further comprising: Screening structure one, wherein the screening structure one is installed on the feed inlet of the reciprocating coal feeder; A pushing structure is provided inside the screening structure 1, which pushes and cleans up large particles of material screened out on the screening structure 1. Screening structure two is disposed on one side of screening structure one; A collection structure is provided on the back of the reciprocating coal feeder.

[0006] Preferably, the screening structure includes a fixed housing, a screening rod, and a square through groove. The fixed housing is fixedly connected to the side wall of the feed inlet of the reciprocating coal feeder. Screening rods are fixedly connected at equal intervals on the inner side wall of the fixed housing. The screening rods are arranged in an arc shape. A square through groove is provided on the side wall of the fixed housing. The height of one end of the screening rod matches the height of the bottom side wall of the square through groove.

[0007] In this technical solution, the material falls onto screen rod one. Smaller particles fall through the gaps between screen rods one and into the reciprocating coal feeder below, while larger particles remain on screen rod two.

[0008] Preferably, a feed funnel is fixedly connected to the top side wall of the fixed housing.

[0009] In this technical solution, the material is fed into the fixed housing through the feeding funnel and falls between the two pusher plates below.

[0010] Preferably, the pushing structure includes a motor, a rotating rod, and a pushing plate. The rotating rod is rotatably connected to the inner side wall of the fixed housing, the motor is fixedly connected to the outer side wall of the fixed housing, the rotating end of the motor is fixedly connected to one end of the rotating rod, and the pushing plate is fixedly connected at equal intervals on the side wall of the rotating rod. The side wall of the pushing plate is attached to the side wall of the screening rod.

[0011] In this technical solution, the motor rotates to drive the rotating rod to rotate, the rotating rod drives the pusher plate to rotate, and the pusher plate drives the material to fall onto the first screening rod. As the pusher plate rotates continuously, the material is conveyed to the first screening rod in segments.

[0012] Preferably, the distance between the two ends of the two opposite push plates on both sides of the rotating rod is consistent with the width of the inner wall of the fixed housing, and the side walls on both sides of the push plates are attached to the inner wall of the fixed housing.

[0013] In this technical solution, when the pusher plate rotates to be perpendicular to the side wall of the fixed housing, a small cavity is formed between the pusher plate and the side wall of the fixed housing to receive the material falling from above, thereby preventing the material from falling directly onto the screening rod.

[0014] Preferably, the collection structure includes a collection shell, a first collection box, a second collection box, a handle frame, a partition plate, and support rods. A partition plate is fixedly connected to the inner side wall of the collection shell. The first collection box is slidably connected to the top side wall of the partition plate. The second collection box is slidably connected to the bottom inner side wall of the collection shell. A handle frame is fixedly connected to the side walls of the first and second collection boxes. Four support rods are fixedly connected to the bottom side wall of the collection shell.

[0015] In this technical solution, the first collection box is used to collect materials with larger particles and impurities, while the second collection box is used to collect materials with smaller particles.

[0016] Preferably, a feed trough is provided on the side wall of the collecting shell near the reciprocating coal feeder, and the feed trough is located between the partition plate and the second collecting box.

[0017] In this technical solution, the feed chute facilitates the entry of small particles of material into the collection box 2.

[0018] Preferably, the top of the collection housing is configured to be open.

[0019] In this technical solution, it is convenient for larger particles to fall into the collection box.

[0020] Preferably, the second screening structure includes a first guide frame, a second square channel, a second screening rod, and a second guide frame. One end of the first guide frame is fixedly connected to the bottom side wall of the square channel, and the other end of the first guide frame is fixedly connected to the top side wall of the collection shell. The second square channel is provided on the bottom side wall of the first guide frame. The second screening rod is fixedly connected at equal intervals on the inner side wall of the second square channel. The second guide frame is fixedly connected to the bottom side wall of the first guide frame, and the other end of the second guide frame is fixedly connected to the bottom inner side wall of the feed channel.

[0021] In this technical solution, larger particles roll down the inclined guide frame 1. When passing the screening rod 2, the remaining small particles will fall onto the guide frame 2 through the gap of the screening rod 2 and be guided into the collection box 2 for collection. The larger particles continue to roll down the guide frame 1 and fall into the collection box 1 for collection.

[0022] Preferably, the spacing between the two screening rods is the same as the spacing between the one screening rods.

[0023] In this technical solution, the particle size screened by screening rod two and screening rod one is consistent.

[0024] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0025] The positive and progressive effects of this utility model are as follows: 1. In this application, the material is fed into the fixed housing through the feeding hopper. The material falls between the two pusher plates below. The motor rotates, which drives the pusher plates to rotate. The pusher plates carry the material down to the first screening rod. As the pusher plates rotate continuously, the material is conveyed to the first screening rod in segments, which facilitates the segmented conveying of the material and avoids excessive material falling at one time, which would cause material accumulation and make screening difficult.

[0026] 2. In this application, the material falls onto the first screening rod. Smaller particles fall through the gap between the first screening rods, while larger particles remain on the second screening rod. As the next pusher plate rotates, the material is pushed toward the square through slot one, which facilitates better screening of the material entering the reciprocating coal feeder and avoids the presence of larger particles or impurities that could cause the reciprocating coal feeder to jam.

[0027] 3. When the larger particles are pushed to the end of the screening rod one by the pusher plate, the larger particles will roll through the square channel two and fall onto the guide frame one. The larger particles will roll down along the inclined guide frame one. When passing the screening rod two, the remaining small particles will fall onto the guide frame two through the gap of the screening rod two. The guide frame two will guide them into the collection box two for collection. The larger particles will continue to roll down along the guide frame one and fall into the collection box one for collection. This facilitates the collection of the larger particles and impurities that are screened out, while also screening and collecting the remaining small particles. Attached Figure Description

[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0037] like Figure 1-7 As shown, an anti-jamming and diversion device for a reciprocating coal feeder includes a reciprocating coal feeder 1, and further includes: Screening structure 2, wherein the screening structure 2 is installed at the feed inlet of the reciprocating coal feeder 1; The pushing structure 4 is set inside the screening structure 2. The pushing structure 4 pushes and cleans the large particles of material screened out on the screening structure 2. Screening structure 2 6 is disposed on one side of screening structure 1 2; Collection structure 5 is disposed on the back side of reciprocating coal feeder 1.

[0038] The screening structure 2 includes a fixed housing 201, screening rods 202, and a square through-slot 203. The fixed housing 201 is fixedly connected to the side wall of the feed inlet of the reciprocating coal feeder 1. Screening rods 202 are fixedly connected at equal intervals on the inner side wall of the fixed housing 201. The screening rods 202 are arranged in an arc shape. The square through-slot 203 is provided on the side wall of the fixed housing 201. The height of one end of the screening rod 202 matches the height of the bottom side wall of the square through-slot 203.

[0039] The material falls onto the first screening rod 202. Smaller particles fall through the gaps between the first screening rods 202 and into the reciprocating coal feeder 1 below, while larger particles remain on the second screening rod 603.

[0040] A feed funnel 3 is fixedly connected to the top side wall of the fixed housing 201.

[0041] The material is fed into the fixed housing 201 through the feed funnel 3, and falls between the two pusher plates 403 below.

[0042] The pushing structure 4 includes a motor 401, a rotating rod 402, and a pushing plate 403. The rotating rod 402 is rotatably connected to the inner side wall of the fixed housing 201, and the motor 401 is fixedly connected to the outer side wall of the fixed housing 201. The rotating end of the motor 401 is fixedly connected to one end of the rotating rod 402. The pushing plate 403 is fixedly connected at equal intervals on the side wall of the rotating rod 402, and the side wall of the pushing plate 403 is attached to the side wall of the screening rod 202.

[0043] The rotation of motor 401 drives the rotation rod 402 to rotate, the rotation rod 402 drives the pusher plate 403 to rotate, the pusher plate 403 drives the material to fall onto the screening rod 202. As the pusher plate 403 rotates continuously, the material is conveyed to the screening rod 202 in segments.

[0044] The distance between the two ends of the two opposite push plates 403 on both sides of the rotating rod 402 is consistent with the width of the inner wall of the fixed housing 201, and the side walls on both sides of the push plates 403 are attached to the inner wall of the fixed housing 201.

[0045] When the pusher plate 403 rotates to be perpendicular to the side wall of the fixed housing 201, a small cavity is formed between the pusher plate and the side wall of the fixed housing 201 to receive the material falling from above, thereby preventing the material from falling directly onto the screening rod 202.

[0046] The collection structure 5 includes a collection shell 501, a first collection box 502, a second collection box 503, a handle 504, a partition plate 505, and support rods 506. The partition plate 505 is fixedly connected to the inner side wall of the collection shell 501. The first collection box 502 is slidably connected to the top side wall of the partition plate 505. The second collection box 503 is slidably connected to the bottom inner side wall of the collection shell 501. The handle 504 is fixedly connected to the side walls of the first collection box 502 and the second collection box 503. Four support rods 506 are fixedly connected to the bottom side wall of the collection shell 501.

[0047] Collector box 1 (502) is used to collect larger particles and impurities, while collector box 2 (503) is used to collect smaller particles.

[0048] The collecting housing 501 has a feeding channel 511 on the side wall near the reciprocating coal feeder 1. The feeding channel 511 is located between the partition plate 505 and the collecting box 503.

[0049] The feed chute 511 facilitates the entry of small particles into the collection box 2 503.

[0050] The top of the collection housing 501 is configured to be open.

[0051] This allows larger particles to fall into the collection box 502.

[0052] The second screening structure 6 includes a first guide frame 601, a second square channel 602, a second screening rod 603, and a second guide frame 604. One end of the first guide frame 601 is fixedly connected to the bottom side wall of the second square channel, and the other end of the first guide frame 601 is fixedly connected to the top side wall of the collection shell 501. The second square channel 602 is provided on the bottom side wall of the first guide frame 601. The second screening rod 603 is fixedly connected at equal intervals on the inner side wall of the second square channel 602. The second guide frame 604 is fixedly connected to the bottom side wall of the first guide frame 601, and the other end of the second guide frame 604 is fixedly connected to the bottom inner side wall of the feed channel 511.

[0053] Larger particles roll down the inclined guide frame 601. When passing the screening rod 603, the remaining small particles fall through the gaps in the screening rod 603 onto the guide frame 604, and are guided by the guide frame 604 to the collection box 503 for collection. The larger particles continue to roll down the guide frame 601 and fall into the collection box 502 for collection.

[0054] The spacing between the two screening rods 603 is consistent with the spacing between the two screening rods 202.

[0055] This ensures that the particle size screened by screening rod 603 and screening rod 202 is consistent.

[0056] In use, all electrical components mentioned in this application are externally connected to a power supply and control switch. The material is fed into the fixed housing 201 through the feeding funnel 3. The material falls between the two pusher plates 403 below. The motor 401 rotates, driving the rotating rod 402 to rotate. The rotating rod 402 drives the pusher plate 403 to rotate. The pusher plate 403 carries the material down to the screening rod 202. As the pusher plate 403 rotates continuously, the material is conveyed to the screening rod 202 in segments, which facilitates better segmented conveying of the material and avoids excessive material falling at once, which would cause material accumulation and make screening difficult. The material falls onto the first screening rod 202. Smaller particles fall through the gaps between the screening rods 202 and into the reciprocating feeder 1 below. Larger particles remain on the second screening rod 603 and are pushed toward the square through-slot 203 as the next pusher plate 403 rotates. This facilitates better screening of the material entering the reciprocating feeder 1 and avoids the presence of large particles or impurities that could cause the reciprocating feeder 1 to jam. When the pusher plate 403 pushes the larger particles to the end of the screening rod 202, the larger particles will roll through the square channel 602 and onto the guide frame 601. The larger particles roll down along the inclined guide frame 601. When passing the screening rod 603, the remaining small particles will fall through the gaps in the screening rod 603 onto the guide frame 604. The guide frame 604 guides them into the collection box 503 for collection. The larger particles continue to roll down along the guide frame 601 and fall into the collection box 502 for collection. This facilitates the collection of the larger particles and impurities that have been screened out, while also screening and collecting the remaining small particles. By pulling out the handle 504, the small particles collected in the collection box 503 can be poured into the feed funnel 3.

The protection scope of this utility model is defined by the appended claims.
