Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain cooling technology, specifically a grain cooler with a structure for separating impurities. Background Technology
[0002] Grain coolers are specially designed based on a comprehensive analysis of the characteristics of grain storage environments and climates. They exchange heat with grains through forced convection to prevent the grains from generating heat due to respiration during storage, thereby reducing the growth of microorganisms and pests caused by respiration and extending the safe storage time of the grains. However, existing grain coolers do not pay enough attention to the separation and treatment of impurities in the grains. There are many types of impurities in grains, including soil, sand, and straw. These impurities not only affect the cooling effect of the grains but also affect the quality of the grains in subsequent processing, requiring manual processing and separation of impurities afterward, which not only increases the processing steps but also wastes time. Utility Model Content
[0003] The purpose of this invention is to provide a grain cooler with a structure for separating impurities, so as to solve the problem mentioned in the background art that impurities cannot be separated during grain cooling.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a grain cooler with a structure for separating impurities, comprising a separation box, a hopper fixedly installed on the outer surface of the separation box, one side of the outer surface of the separation box being inclined, and a discharge port opened at the end of the separation box away from the hopper, an electric push rod fixedly installed on the inclined side of the separation box, a drive motor fixedly installed inside one end of the separation box, a fan blade rotatably installed on one side of the outer surface of the separation box, and a first pulley transmission assembly fixedly installed between the fan blade and the drive motor, a filter bag being fitted and snapped onto the end of the separation box away from the fan blade, and the filter bag being inclined, and a filter evaporator assembly fixedly installed on the outer surface of the separation box, and the filter evaporator assembly and the fan blade being concentrically designed, and the fan blade and the filter bag being at the same height.
[0005] Preferably, a partition is slidably installed on the outer surface of the hopper, and the partition engages with the hopper. A servo gear motor is fixedly installed on the side surface of the hopper, and the servo gear motor meshes with the outer surface of the partition. A cam is rotatably installed on the outer surface of the hopper, and a rotating striking mechanism is provided between the cam and the partition.
[0006] By adopting the above technical solution, the rotation of the servo gear motor can drive the meshing partition to move, allowing the opening and closing gap between the hopper and the partition to be adjusted, thereby controlling the feeding speed and amount of grain and improving the cleaning effect of the fan blades on impurities in different grains.
[0007] Preferably, the rotating striking mechanism includes: a second pulley transmission assembly, which is fixedly installed between the drive motor and the rotating shaft of the cam; a rubber striking hammer is rotatably installed on the outer surface of the hopper, and one end of the outer surface of the rubber striking hammer is in contact with the outer surface of the cam, while the end of the rubber striking hammer away from the cam is in contact with the outer surface of the partition.
[0008] Using the above technical solution, when the drive motor drives the fan blades to rotate, it will simultaneously drive the cam to rotate synchronously, allowing the cam to push the rubber hammer to strike the partition. This allows the fan blades to blow air and cool the grains while ensuring that the grains stored inside the hopper do not become clogged, ensuring that the hopper can discharge the grains evenly, and allowing impurities in the grains to be better separated.
[0009] Preferably, a flexible lip ring is fixedly installed on the outer surface of the filter bag, and the flexible lip ring engages with the outer surface of the separation box. A clamping and engaging mechanism is provided between the separation box and the filter bag.
[0010] By adopting the above technical solution, the flexible lip ring allows the filter bag to be installed on the side surface of the separation box and, together with the clamp, tighten, improving the stability of the filter bag. This prevents the filter bag from accidentally falling off when it is tapped later, and also makes it easy to remove the filter bag for cleaning and take out the collected debris.
[0011] Preferably, the clamping and engaging mechanism includes: a clamp, the outer surface of which is fixedly fitted with a protruding buckle edge, which engages with the outer surface of the separation box, the outer surface of the separation box is in contact with the outer surface of the clamp, and the outer surface of the clamp is engaged with a flexible lip ring, and the outer surface of the filter bag is in contact with the outer surfaces of the separation box and the clamp respectively.
[0012] By adopting the above technical solution, the protruding buckle edge makes the clamp more securely fixed to the outer surface of the separation box, so that the separation box will not separate from the clamp.
[0013] Preferably, a beating rod is rotatably mounted on the outer surface of the separation box near the filter bag, and a striking rod is rotatably mounted on the outer surface of the separation box near the beating rod, and a pushing and beating mechanism is provided between the striking rod, the beating rod and the electric push rod.
[0014] By adopting the above technical solution, the deflection guide rod can be moved by the electric push rod, so that the deflection guide rod can simultaneously drive the slapping rod and the striking rod to rotate, so that the slapping rod and the striking rod can work together to achieve different functions.
[0015] Preferably, the pushing and tapping mechanism includes: a deflecting guide rod, which is fixedly installed on the outer surface of the output end of the electric push rod, and the output end of the electric push rod passes through the tapping rod and the striking rod respectively. The outer surface of one end of the tapping rod is railing-shaped and is located below the filter bag. The one end of the striking rod is located below the discharge port of the separation box. The outer surface of the deflecting guide rod is in contact with the outer surfaces of the tapping rod and the striking rod respectively.
[0016] By adopting the above technical solution, the railing-shaped design of the beater bar allows for more thorough beating of the filter bag after the beater bar rotates, preventing dust and debris from clogging the filter bag's mesh and causing insufficient filtration. The rotation of the striking bar can also strike the discharge port of the separation box, preventing the grains that have been separated from impurities from accumulating at the discharge port.
[0017] Compared with the prior art, the beneficial effects of this utility model are: the grain cooler with a structure for separating impurities:
[0018] 1. After the drive motor rotates, it will drive the fan blades to rotate through the first pulley transmission assembly, so that the falling grains can be cooled by the air blown out by the fan blades. At the same time, the air blown out by the fan blades separates the impurities in the grains, so that the blown impurities can enter the interior of the filter bag with the air, allowing the impurities in the grains to be separated and stored inside the filter bag, which facilitates the separation of grain impurities and the storage of impurities at the same time.
[0019] 2. As the drive motor drives the fan blades to rotate, the second pulley transmission assembly will rotate along with it and drive the cam to rotate. The cam can push the rubber hammer to rotate, so that the rubber hammer can strike the partition as the fan blades rotate. This prevents the grain stored in the hopper from clogging due to accumulation, and allows the grain stored in the hopper to be evenly discharged and enter the interior of the separation box. The grain will not block the flow and cause processing delays.
[0020] 3. After the electric push rod pushes out the deflection guide rod, the deflection guide rod will simultaneously push the slapping rod and the striking rod, allowing the slapping rod and the striking rod to rotate on the outer surface of the separator. This allows the slapping rod to slap the outer surface of the filter bag, while the deflection guide rod can strike the discharge port of the separator, ensuring that the filter bag is not clogged by debris and dust, and preventing the processed grain from accumulating at the discharge port of the separator.

[0028] 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.
[0029] Please see Figure 1-6 This utility model provides a technical solution: a grain cooler with a structure for separating impurities, including a separation box 1, a hopper 6 fixedly installed on the outer surface of the separation box 1, one side of the outer surface of the separation box 1 is inclined, and a discharge port is opened at the end of the separation box 1 away from the hopper 6. An electric push rod 16 is fixedly installed on the inclined side of the separation box 1. A drive motor 3 is fixedly installed inside one end of the separation box 1. A fan blade 2 is rotatably installed on one side of the outer surface of the separation box 1, and a first pulley transmission assembly 4 is fixedly installed between the fan blade 2 and the drive motor 3. A filter bag 12 is attached and snapped to the end of the separation box 1 away from the fan blade 2, and the filter bag 12 is inclined. A filter evaporator assembly 5 is fixedly installed on the outer surface of the separation box 1, and the filter evaporator assembly 5 and the fan blade 2 are concentrically designed, and the fan blade 2 and the filter bag 12 are at the same height.
[0030] The rotation of the drive motor 3 drives the fan blades 2 connected to the first pulley transmission assembly 4 to rotate. The use of the filter evaporator assembly 5 can filter the air and cool the passing air, so that the air blown out by the fan blades 2 can cool the grains put into the separation box 1. At the same time, the air blown out by the fan blades 2 can separate the impurities in the falling grains, so that the impurities can be carried into the interior of the filter bag 12 by the wind. The inclined design of the filter bag 12 allows the impurities to collect at the bottom of the filter bag 12, so that the grains can be cooled while the impurities are separated. The impurities can also be stored for easy cleaning later, reducing the time and procedures spent on separation.
[0031] A partition 7 is slidably installed on the outer surface of the hopper 6, and the partition 7 is engaged with the hopper 6. A servo gear motor 8 is fixedly installed on the side surface of the hopper 6, and the servo gear motor 8 meshes with the outer surface of the partition 7. A cam 9 is rotatably installed on the outer surface of the hopper 6, and a rotating striking mechanism is provided between the cam 9 and the partition 7.
[0032] The position of the baffle 7 inside the hopper 6 can be adjusted by rotating the servo gear motor 8, so that the opening and closing distance between the hopper 6 and the baffle 7 can be adjusted, and the amount of grain discharged from the hopper 6 can be adjusted. The amount of grain discharged from the hopper 6 can be adjusted according to different types of grains, so that the fan blade 2 can perfectly separate impurities in different grains.
[0033] The rotating striking mechanism includes: a second pulley transmission assembly 10, which is fixedly installed between the drive motor 3 and the rotating shaft of the cam 9. A rubber striking hammer 11 is rotatably installed on the outer surface of the hopper 6, and one end of the outer surface of the rubber striking hammer 11 is in contact with the outer surface of the cam 9, while the end of the rubber striking hammer 11 away from the cam 9 is in contact with the outer surface of the partition 7.
[0034] When the drive motor 3 drives the fan blade 2 to rotate, the second pulley transmission assembly 10 will rotate along with it, so that the cam 9 can rotate synchronously with the fan blade 2. The rotation of the cam 9 pushes the rubber hammer 11 to swing, so that the rubber hammer 11 can strike the partition 7, so that the grain stored in the hopper 6 will not be blocked due to accumulation or other reasons, and the grain in the hopper 6 can be evenly discharged into the separation box 1, ensuring the separation efficiency of impurities in the grain.
[0035] A flexible lip ring 13 is fixedly installed on the outer surface of the filter bag 12, and the flexible lip ring 13 is engaged with the outer surface of the separation box 1. A clamping and engaging mechanism is provided between the separation box 1 and the filter bag 12.
[0036] The filter bag 12 can be pre-fixed to the side surface of the separation box 1 by means of the flexible lip ring 13. Then the clamp 14 can be snapped and installed on one side of the separation box 1. The clamp 14 can press against the flexible lip ring 13, which improves the firmness of the filter bag 12 after installation, so that the filter bag 12 will not fall off accidentally when the beater 17 beats the filter bag 12.
[0037] The clamping mechanism includes: a clamp 14, on the outer surface of which a protruding snap-fit edge 15 is fixedly installed, and the protruding snap-fit edge 15 engages with the outer surface of the separation box 1. The outer surface of the separation box 1 is in contact with the outer surface of the clamp 14, and the outer surface of the clamp 14 engages with the flexible lip ring 13. The outer surface of the filter bag 12 is in contact with the outer surfaces of the separation box 1 and the clamp 14 respectively.
[0038] The protruding buckle edge 15 allows the clamp 14 to be firmly connected to the separation box 1 after installation and tightening, further strengthening the firmness of the filter bag 12 installed on the outer surface of the separation box 1. At the same time, the clamp 14 can be easily disassembled to clean the filter bag 12 and to process the debris collected inside the filter bag 12.
[0039] A beating rod 17 is rotatably mounted on the outer surface of the separation box 1 near the filter bag 12, and a striking rod 18 is rotatably mounted on the outer surface of the separation box 1 near the beating rod 17. A pushing and beating mechanism is provided between the striking rod 18, the beating rod 17 and the electric push rod 16.
[0040] The slapping rod 17 and the striking rod 18 can work synchronously by pushing the deflection guide rod 19 out of the electric push rod 16. When the electric push rod 16 retracts, the slapping rod 17 and the striking rod 18 will automatically return to their original positions due to their own weight.
[0041] The pushing and tapping mechanism includes a deflection guide rod 19, which is fixedly installed on the outer surface of the output end of the electric push rod 16. The output end of the electric push rod 16 passes through the tapping rod 17 and the striking rod 18 respectively. One end of the tapping rod 17 has a railing-shaped outer surface and is located below the filter bag 12. One end of the striking rod 18 is located below the discharge port of the separation box 1. The outer surface of the deflection guide rod 19 is in contact with the outer surfaces of the tapping rod 17 and the striking rod 18 respectively.
[0042] The tapping rod 17 can tap the filter bag 12 to prevent dust inside the filter bag 12 from clogging the mesh and to maintain ventilation in the filter bag 12. The tapping rod 18 can rotate to tap the discharge port of the separator 1 to prevent the grain after processing and separating impurities from accumulating at the discharge port of the separator 1, so that the filter bag 12 will not be blocked and affect the grain separation effect, and the grain will not accumulate at the discharge port of the separator 1 and be unable to be discharged.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
