Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, specifically to a rapid grain pulverizer. Background Technology

[0002] Cereals mainly refer to the seeds of grasses (Poaceae). The five major grains include rice, wheat, corn, and other miscellaneous grains such as millet, black rice, buckwheat, oats, Job's tears, and sorghum. Grains are processed into staple foods. Before processing grains, they need to be crushed, which requires crushing equipment. After crushing, because the grains are relatively moist, they need to be dried, which requires drying equipment. However, crushing and drying equipment are two separate pieces of equipment, meaning that crushing and drying cannot be performed in the same system, affecting the efficiency of grain processing. Utility Model Content

[0003] To address the problems of existing technologies, this utility model provides a rapid grain grinder, including a grinding chamber. A partition is provided inside the grinding chamber, and the two ends of the partition are fixedly connected to the two inner side walls of the grinding chamber, respectively. The partition divides the interior of the grinding chamber into a grinding chamber and a drying chamber. A vertical through hole is provided on the partition, and the grinding chamber and the drying chamber are connected through the through hole. The crushing box is equipped with a multi-stage crushing mechanism for crushing grains. The multi-stage crushing mechanism includes a primary crushing roller group and a secondary crushing roller group, both fixedly installed inside the crushing box. Two auxiliary baffles are symmetrically distributed between the primary and secondary crushing roller groups, and a flow divider is set between the two auxiliary baffles. The flow divider and the auxiliary baffles on both sides form auxiliary feeding hoppers respectively. The secondary crushing roller group is configured as two groups, and the two groups of secondary crushing roller groups are respectively set directly above the two auxiliary feeding hoppers.

An electric heating tube is fixedly installed at the bottom of the partition, and a magnetron is fixedly installed on the inner wall of the drying chamber. Both the electric heating tube and the magnetron are located directly above the conveyor belt. The electric heating tube is electrically connected to an external control terminal, and the magnetron is connected to a microwave generator.

[0004] A further embodiment is that the primary crushing roller assembly includes two symmetrically arranged first crushing rollers, and the two first crushing rollers are respectively connected to the power output shafts of two first rotating motors; The secondary crushing roller assembly includes two symmetrically arranged second crushing rollers, each of which is connected to the power output shaft of a second rotating motor.

[0005] A further embodiment is that the diversion baffle is in the shape of an inverted V, and the top of the diversion baffle is located directly below the primary crushing roller assembly.

[0006] A further option is to fix baffles on both the front and rear sides of the conveyor belt.

[0007] A further embodiment includes a leveling mechanism installed on the baffle to spread the crushed grain on the conveyor belt. The leveling mechanism includes a first drive motor and a rotating rod. The drive motor is fixed to the side of the baffle 5 away from the conveyor belt. The rotating rod is rotatably connected between two baffles. The power output shaft of the drive motor passes through one of the baffles and is connected to one end of the rotating rod. A cylinder is fixedly connected to the outer surface of the rotating rod. Several first spreading columns are fixedly connected to the lower part of the outer surface of the cylinder. Second spreading columns are fixedly connected to the upper part of the outer surface of the cylinder.

Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figure 1-3As shown, one embodiment of this utility model discloses a rapid grain pulverizer, including a pulverizing chamber 1. A feed inlet is located at the center of the top of the pulverizing chamber 1, and an automatic feeding mechanism is located above the feed inlet. The automatic feeding mechanism includes a conveying cylinder 70, which is fixedly mounted on the top of the pulverizing chamber 1 by a support block 75. A feed hopper 71 is located above one side of the conveying cylinder 70, and a second drive motor 72 is located on one side of the conveying cylinder 70. The second drive motor 72 is connected to the bottom of the conveying cylinder 70 via a mounting plate 76. A rotating shaft 73 is rotatably connected inside the conveying cylinder 70, and several spiral blades 74 are fixedly connected to the surface of the rotating shaft 73. The power output shaft of the second drive motor 72 passes through the conveying cylinder 70 and is connected to one end of the rotating shaft 73. A discharge port 77 is located on the side of the conveying cylinder 70 away from the second drive motor 72, and the discharge port 77 communicates with the feed inlet of the pulverizing chamber 1.

[0016] This embodiment, through the above-described configuration, enables the feeding of a certain amount of grain material to be crushed into the conveying cylinder via the feeding hopper. Once the grain material falls into the conveying cylinder, the second drive motor is activated. The power output shaft of the second drive motor rotates, driving the rotating shaft to rotate, which in turn drives the spiral blades to rotate. This causes the material in the conveying cylinder to move towards the discharge port and fall from the discharge port into the crushing chamber. This achieves automatic and uniform feeding of materials into the crushing chamber, avoiding the incomplete crushing caused by manually feeding too much material at once.

[0017] In this embodiment, a partition 10 is provided inside the crushing box 1, and the two ends of the partition 10 are fixedly connected to the two inner side walls of the crushing box 1 respectively; the partition 10 divides the interior of the crushing box 1 into a crushing chamber 11 and a drying chamber 12; a vertical through hole 100 is provided on the partition 10, and the crushing chamber 11 and the drying chamber 12 are connected through the through hole 100. This embodiment enables the grain material to be crushed first, and then the crushed grain to be dried, thus realizing the integrated operation of crushing and drying of grain material.

[0018] In this embodiment, a multi-stage crushing mechanism for crushing grains is provided inside the crushing box 1. The multi-stage crushing mechanism includes a primary crushing roller group 20 and a secondary crushing roller group 21, both fixedly installed inside the crushing box 1. Two auxiliary baffles 22 are symmetrically distributed between the primary crushing roller group 20 and the secondary crushing roller group 21, and a diversion baffle 23 is provided between the two auxiliary baffles 22. The diversion baffle 23 and the auxiliary baffles 22 on both sides form auxiliary feeding hoppers 24 respectively. The secondary crushing roller group 21 is configured as two groups, and the two groups of secondary crushing roller groups 21 are respectively located directly above the two auxiliary feeding hoppers 24. The diversion baffle 23 is inverted V-shaped, and the top of the diversion baffle 23 is located directly below the primary crushing roller group 20.

[0019] The primary crushing roller assembly 20 includes two symmetrically arranged first crushing rollers 200, and the two first crushing rollers 200 are respectively connected to the power output shafts of two first rotating motors; The secondary crushing roller group 21 includes two symmetrically arranged second crushing rollers 210, and the two second crushing rollers 210 are respectively connected to the power output shafts of two second rotating motors.

[0020] The two first rotary motors and the two second rotary motors are all controlled by an external control terminal to start and stop. This allows both first rotary motors to rotate simultaneously, and both second rotary motors to rotate simultaneously.

[0021] This embodiment, through the above-described configuration, enables the activation of a primary crushing roller group and two secondary crushing roller groups. As the grain material enters the crushing chamber of the crushing box and falls within it, it undergoes primary crushing by the primary crushing roller group. The material after primary crushing continues to fall and is diverted by the diverting baffle to the auxiliary feed hoppers on both sides, and then falls onto the two secondary crushing roller groups for secondary crushing. This significantly improves the efficiency of material crushing and ensures the effectiveness of material crushing.

[0022] In this embodiment, guide blocks 14 are fixedly provided on both sides of the inner wall of the crushing chamber 11. Each guide block 14 is provided with an inclined surface, and the bottom of the inclined surface of both guide blocks 14 extends to the through hole 100.

[0023] In this embodiment, the above-mentioned settings allow some of the material after two crushing processes to directly pass through the through hole and fall into the drying chamber. Additionally, some of the crushed material can fall onto the two guide blocks and slide down the inclined surface of the guide blocks to the through hole, then pass through the through hole and fall into the drying chamber, ensuring that all the crushed material can enter the drying chamber for drying.

[0024] In this embodiment, a conveyor belt 3 for transporting pulverized grains is provided inside the drying chamber 12. A discharge port 13 is provided on the lower side of one side of the pulverizing chamber 1, and the output end of the conveyor belt 3 extends to the discharge port 13. The input end of the conveyor belt 3 is located below the through hole 100. An electric heating tube 40 is fixedly provided at the bottom of the partition 10, and a magnetron 41 is fixedly provided on the inner wall of the drying chamber 12. Both the electric heating tube 40 and the magnetron 41 are located directly above the conveyor belt 3. The electric heating tube 40 is electrically connected to an external control terminal, and the magnetron 41 is connected to a microwave generator. A discharge port 13 is provided on the lower side of one side of the pulverizing chamber 1, and the output end of the conveyor belt 3 extends to the discharge port 13.

[0025] It should be noted that the heating element, when energized, raises the temperature inside the drying chamber. By activating an external microwave generator, the magnetron emits electromagnetic waves that rapidly vaporize and evaporate the moisture on the surface of the material. Therefore, both the heating element and the magnetron can be used to dry the pulverized grain material.

[0026] In this embodiment, the material after two crushing processes falls through the through hole onto the input end of the conveyor belt. By starting the conveyor belt, the material is dried by the electric heating tube and magnetron during the process of being transported to the discharge port.

[0027] In this embodiment, baffles 5 are fixedly installed on the front and rear sides of the conveyor belt 3.

[0028] This embodiment uses a baffle to ensure that material falling from the through-hole onto the conveyor belt does not... In this embodiment, a leveling mechanism is installed on the baffle 5 to flatten the crushed grain on the conveyor belt 3. The leveling mechanism includes a first drive motor 60 and a rotating rod 61. The drive motor 60 is fixed on the side of the baffle 5 away from the conveyor belt 3. The rotating rod 61 is rotatably connected between two baffles 5. The power output shaft of the drive motor 60 passes through one of the baffles 5 and is connected to one end of the rotating rod 61. A cylinder 62 is fixedly connected to the outer surface of the rotating rod 61. Several first spreading columns 63 are fixedly connected to the lower part of the outer surface of the cylinder 62. Second spreading columns 64 are fixedly connected to the upper part of the outer surface of the cylinder 62. A first channel 65 for the crushed grain to pass through is provided between two adjacent first spreading columns 63. A second channel 66 for the crushed grain to pass through is provided between two adjacent second spreading columns 64.

[0029] It should be noted that the length of all the first and second spreading columns in this embodiment can be set according to actual requirements, as long as all the first and second spreading columns can contact the material on the conveyor belt when they rotate with the rotating rod to the bottom of the cylinder, that is, the material on the conveyor belt can pass through the first and second channels.

[0030] This embodiment, through the above-described setup, allows for material accumulation on the conveyor belt when the twice-crushed grain falls to the input end. Direct drying in this case would result in some material remaining undried. At this point, the first drive motor is activated, its power output shaft rotating to drive a rotating rod, which in turn rotates a cylinder. This cylinder, in turn, rotates several first spreading columns and several second spreading columns. When these columns are directly below the cylinder, the material on the conveyor belt passes through these first or second channels, resulting in evenly spread material on the conveyor belt. The material is then dried using heating elements and a magnetron, improving the drying effect and ensuring all material is dried.

[0031] In this embodiment, the conveyor belt 3 is tensioned on two drive rollers 30, and the two ends of the drive rollers 30 are hinged to two corresponding bearing seats 31.

[0032] This embodiment achieves the installation and fixation of the conveyor belt through the above settings.

[0033] Finally, it should be noted that the above description only details specific embodiments of this utility model. However, this utility model is not limited to the specific embodiments described above. Equivalent modifications and substitutions made to this utility model by those skilled in the art are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model are covered within the scope of this utility model.
