Description

Technical Field

[0001] This utility model relates to the technical field of grain impurity removal and feeding equipment, specifically to a grain impurity removal and feeding bin. Background Technology

[0002] In the grain processing industry, feeding and impurity removal are key preliminary processes that directly affect the quality and efficiency of subsequent processing. Currently, screw feeders, which are widely used in the market due to their continuous feeding and good sealing performance, are often used in combination with drum screening equipment to form an integrated feeding-screening process, used to remove impurities such as stones, soil, and straw from grains.

[0003] In related technologies, a feeding bin is set at the inlet end of the screw feeder to feed the screw conveyor. The feeder then feeds the grain through the screw shaft and screw channel inside the screw conveyor to the outlet end of the screw conveyor. A screening cylinder is then set at the outlet end of the screw conveyor to remove impurities and screen the grain.

[0004] However, this type of impurity-removing feeding bin has the problem of secondary dust generation when grain falls into it. Furthermore, if grain accumulates in the feeding bin, it can easily cause blockage of the screw conveyor, requiring manual shutdown for maintenance and unblocking, which affects work efficiency. To solve the above problems, a grain impurity-removing feeding bin is proposed. Utility Model Content

[0005] In view of this, the present invention provides a grain impurity removal feeding bin. The present invention uses a fan combined with a dust suction pipe to extract the dust raised when the grain is fed into the feeding bin. The dust is filtered through a filter box and a dust collection bag, and the filtered gas is discharged into the atmosphere, thereby reducing air pollution. When the feeding bin is blocked, the distance between the unblocking rods can be adjusted by pulling the handle, so that the material can be unblocked without stopping the machine.

[0006] To solve the above-mentioned technical problems, this utility model provides a grain impurity removal and feeding bin, including a screw conveyor mounted on a frame, a feeding bin mounted at the top inlet of the screw conveyor, an impurity removal cylinder mounted at the outlet of the screw conveyor, a waste bin connected to the lower part of the impurity removal cylinder, a discharge pipe connected to the outlet of the impurity removal cylinder, a separation cylinder mounted in the middle of the impurity removal cylinder, a separation component mounted inside the separation cylinder, the separation component being rotatably connected to the screw shaft inside the screw conveyor, a maintenance bin door hinged to one side of the top of the impurity removal cylinder, a feeding pipe connected to the top of the feeding bin, a dust removal component mounted at the bottom of the feeding bin, a fan connected to the outlet of the dust removal component, a filter box connected to the outlet of the fan, a dust collection bag connected to the bottom of the filter box, a frame mounted on the surface of the filter box, and multiple unblocking rods mounted on the inner side wall of the feeding bin.

[0007] The surface of the separating cylinder is detachably equipped with multiple sieve plates. The sieve plates are used to screen out stones and dust in the grain. The sieve plates are arc-shaped and have several sieve holes on their surface. The sieve holes are used to filter out stones and dust.

[0008] A discharge hopper is connected to the side of the separator cylinder away from the feed hopper. The discharge hopper is used to install bearing seats, thereby supporting the separator shaft and the screw shaft in the screw conveyor. A bearing seat is set in the middle of the discharge hopper, which is used to install the separator shaft and reduce the axial stress of the separator shaft. A discharge pipe is installed at the bottom of the discharge hopper at an incline.

[0009] The separation assembly includes a separation shaft that is rotatably connected to the screw shaft of the screw conveyor. The separation shaft is used to install separation blades. The other end of the separation shaft is rotatably connected to a bearing seat. Multiple separation blades are provided on the surface of the separation shaft. The separation blades are used to lift and turn the grain in the separation cylinder. The separation blades are also used to combine with the inner arc surface of the screen plate to scatter the lifted grain, thereby causing stones and dust to fall from the screen plate and the grain to enter the discharge pipe.

[0010] The dust removal assembly includes an opening through the wall of the feeding hopper. A filter screen is installed on the inner side of the opening to prevent foreign objects from being sucked into the fan and contaminating the internal parts of the fan. The filter screen is circular. A dust suction pipe is installed on the outer side of the opening to connect the feeding hopper to the fan and to the air inlet of the fan.

[0011] The filter box contains multiple detachable filter plates. These plates filter dust generated when grain falls through the filter box. Each filter plate has a positioning bracket on both its left and right sides to fix it in place, thus connecting it to the inner wall of the filter box and providing support. Each filter plate has a handle on the side away from the feed hopper, allowing for easy removal from the filter box. Each handle also has a sealing plate to block the removal opening and prevent the filter plate from falling off. The sealing plate is bolted to the wall of the filter box.

[0012] A dust collection pipe is connected to the bottom of the filter box, which is used to connect the dust collection bag to the filter box. The feed inlet at the top of the dust collection bag is detachably connected to the dust collection pipe via a flange. The dust collection bag is placed on the frame.

[0013] Each unclogging rod has a receiving seat on the side near the blower. The receiving seat is used to receive the limiting block, allowing the unclogging rod to be supported horizontally in the feeding bin. The receiving seat is fixed in the feeding bin on the side near the blower. Each receiving seat has a receiving ring on its opposite side. The receiving ring is used to support the unclogging rod to prevent the limiting block from exceeding its limit. The unclogging rod can slide on the receiving ring to prevent blockage in the feeding bin. The unclogging rod can slide on the inner ring of the receiving ring. The unclogging rod has a handle at one end near the receiving ring for easy insertion and removal. The other end of the unclogging rod has a limiting block to prevent the unclogging rod from slipping off the receiving ring. The limiting block is circular and its size is larger than that of the receiving ring.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The dust raised when grain is fed into the feeding hopper is extracted by a blower and a dust suction pipe. The dust is filtered through a filter box and a dust collection bag, and the filtered gas is discharged into the atmosphere, thereby reducing air pollution. When the feeding hopper is blocked, the distance between the unblocking rods can be adjusted by pulling the handle, so that the material can be unblocked without stopping the machine.

[0015] 2. The filter plate filters the dust generated during grain feeding. The positioning frame is used to fix the filter plate, thereby connecting the filter plate to the inner wall of the filter box and supporting the filter plate. The handle is square and fixed to the filter plate with bolts. The handle makes it easy to pull the filter plate out of the filter box. The sealing plate is used to block the disassembly port of the filter plate to prevent the filter plate from falling off by itself. The sealing plate is fixed to the wall of the filter box with bolts and also facilitates the subsequent cleaning of the filter plate.

[0016] 3. After passing through the feeding bin, the grain enters the screw conveyor. The screw conveyor pushes the grain into the separation cylinder in the impurity removal bin through the screw channel. When the screw shaft of the screw conveyor rotates, the separation shaft rotates synchronously, which in turn drives the separation blades to rotate, stirring and separating the grain in the separation cylinder. This causes the dirt and dust to fall into the impurity bin for discharge. The grain after impurity removal falls into the discharge pipe through the discharge bin for collection. After collection, it is fed to the subsequent processes. Attached Figure Description

[0032] Working principle: Grain is quantitatively fed into the feeding bin 101 through the feeding pipe 106. The blower 301 is started to extract the dust raised when the grain falls into the feeding bin 101 through the dust suction pipe. The dust is then filtered through the filter plate 402 in the filter box 400. Finally, the dust-laden gas passes through the dust collection bag 401 to collect the dust particles at the end, and the gas is discharged into the atmosphere, thereby reducing air pollution. After passing through the feeding bin 101, the grain enters the screw conveyor 100. The screw conveyor 100 pushes the grain into the separation cylinder 200 in the impurity removal bin through the screw channel. When the screw shaft of the screw conveyor 100 rotates, the separation shaft 206 rotates synchronously, which in turn drives the separation blade 207 to rotate, stirring and separating the grain in the separation cylinder 200. The dirt and dust fall into the impurity bin 103 for discharge. The impurity-removed grain falls into the discharge pipe 104 through the discharge bin 204 for collection. After collection, it is fed to the subsequent process.
