Description

Technical Field

[0001] This utility model relates to the field of grain drying machinery technology, specifically a grain dispersing mechanism for a grain dryer. Background Technology

[0002] Grain drying is a crucial step in grain storage and processing. However, traditional grain drying machinery often suffers from uneven grain distribution during the feeding process, which not only affects drying efficiency but may also lead to inconsistent grain quality after drying. Therefore, developing a grain dispersing mechanism for grain dryers is of great significance for improving drying efficiency and quality.

[0003] Referring to the grain dispersing mechanism for a grain dryer (CN221005882U), it includes a feeding box and a dispersing feeding box. The dispersing feeding box is fixedly installed below the feeding box and is interconnected. The dispersing feeding box is fixedly installed on the dryer and connected to it. The dispersing mechanism has several grain dispersing plates inside the dispersing feeding box, arranged in groups of two to guide and disperse the incoming grain. Other groups of grain dispersing plates also guide and disperse the grain. This allows the grain to enter the dryer quickly while effectively dispersing it, maximizing the grain's entry efficiency and avoiding large height differences in the grain distribution. While this dispersing mechanism can be effectively applied, it typically involves opening and closing multiple valves and using multiple dispersing mechanisms to disperse the grain. This results in a high grain discharge rate, but it still makes it difficult for the grain to fully contact the heat energy for drying. Further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a grain dispersing mechanism for a grain dryer, in order to solve the problem mentioned in the background art that although the dispersing mechanism can be well applied, it usually involves opening and closing multiple valves and cooperating with multiple dispersing mechanisms to disperse the grain, resulting in a high grain discharge rate, but it is still difficult to fully contact the heat energy for drying.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grain dispersing mechanism for a grain dryer, comprising a dryer body, a grain inlet on one side of the top of the dryer body, a support seat on the upper outer wall of one side of the dryer body, a positioning seat on one side of the top of the support seat, a telescopic drive component installed on the inner wall of the positioning seat, a support plate on the end of the telescopic drive component away from the positioning seat, two limiting rails on the top of the support seat below the support plate, a rail seat slidably connected to one side of the top of each limiting rail, the top of the rail seat connected to the bottom of the support plate, a stand on one side of the top of the support plate, a component rack on the inner wall of the upper end of the stand, a screw conveyor body on the inner wall of the component rack, a grain storage hopper on one side of the top of the screw conveyor body, a grain discharge port on one side of the bottom of the screw conveyor body, and a guide frame on the bottom of the screw conveyor body outside the grain discharge port.

[0006] Preferably, a purification box is provided at the top of the support plate on one side of the stand, and an exhaust port is provided on the outer wall of one side of the purification box. The purification box is provided to purify the dusty air generated during the grain dispersion and injection process.

[0007] Preferably, a spiral roller is rotatably installed inside the spiral conveyor body, and a geared motor is installed on the outer wall of the upright. One end of the geared motor extends into the interior of the spiral conveyor body and is connected to one end of the spiral roller. The geared motor is configured to drive the spiral roller to rotate.

[0008] Preferably, the outer walls on both sides of the grain storage hopper are provided with diagonal bracing ribs, and the bottom end of the diagonal bracing ribs is fixedly connected to the top end of the placement frame. The diagonal bracing ribs are provided to improve the firmness between the screw conveyor body and the placement frame.

[0009] Preferably, the top of the purification box is equipped with an exhaust fan via a bracket. One end of the exhaust fan is equipped with an air extraction hood, and the other end of the exhaust fan is connected to the outer wall of the purification box. The exhaust fan is designed to draw the dust-laden air generated during the grain dispersion and injection into the interior of the purification box.

[0010] Preferably, a rotary drive component is installed at the top of the purification box on one side of the exhaust fan. One end of the rotary drive component is connected to the inner wall of the exhaust fan. The rotary drive component is used to drive the exhaust fan to operate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the grain dispersion mechanism of the grain dryer not only ensures the dispersion and drying effect of the grain, but also makes it easy to control the grain dispersion injection rate, and improves the environmental friendliness of the dispersion mechanism during use.

[0012] (1) Grain inside the screw conveyor is discharged into the dryer body through the discharge port and guide frame. During this process, the telescopic drive drives the bearing plate to move horizontally, so that the bearing plate drives the rail seat to slide at the top of the limit rail, so that the bearing plate drives the guide frame to move smoothly, and the grain can be evenly dispersed and injected into the dryer body, so as to ensure that the grain is fully in contact with the heat energy inside the dryer body for drying, thereby ensuring the dispersion and drying effect of the grain.

[0013] (2) By injecting grain into the storage hopper, the grain falls into the screw conveyor body due to gravity. The screw roller is driven by the geared motor to rotate, so that the screw roller conveys the grain inside the screw conveyor body in a screw conveyor, so that the grain is guided out from the discharge port and the guide frame. The geared motor can control the speed of the screw roller, thus making it easy to control the dispersion injection rate of the grain.

[0014] (3) The exhaust fan is driven by the rotating drive component, so that the exhaust fan draws the dust-laden air generated during the grain dispersion and injection process into the purification box through the exhaust hood. The dust-laden gas is filtered and purified by the purification box and then discharged through the exhaust port, thus achieving the purpose of purifying the air and improving the environmental friendliness of the dispersion mechanism.

[0023] The top of the purification box 12 is equipped with an exhaust fan 14 via a bracket. One end of the exhaust fan 14 is equipped with an exhaust hood 15, and the other end of the exhaust fan 14 is connected to the outer wall of the purification box 12.

[0024] During use, the exhaust fan 14 is set up to draw the dusty air generated when the grain is dispersed and injected into the purification box 12.

[0025] A rotary drive component 13 is installed on the top of the purification box 12 on one side of the exhaust fan 14, and one end of the rotary drive component 13 is connected to the inner wall of the exhaust fan 14.

[0026] In use, the exhaust fan 14 is driven to operate by rotating the drive component 13.

[0027] The upper inner wall of the upright frame 7 is provided with a component rack 8, the inner wall of the component rack 8 is provided with a screw conveyor body 9, a screw roller 18 is rotatably installed inside the screw conveyor body 9, and a reduction motor 19 is installed on the outer wall of the upright frame 7. One end of the reduction motor 19 extends into the interior of the screw conveyor body 9 and is connected to one end of the screw roller 18.

[0028] In use, the geared motor 19 is configured to drive the spiral roller 18 to rotate;

[0029] A grain storage hopper 11 is provided on one side of the top of the screw conveyor body 9. Diagonal bracing ribs 20 are provided on the outer walls of both sides of the grain storage hopper 11. The bottom end of the diagonal bracing ribs 20 is fixedly connected to the top of the component rack 8.

[0030] In use, the diagonal bracing ribs 20 are used to improve the stability between the screw conveyor body 9 and the component holder 8;
