Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, specifically a novel grain dryer. Background Technology

[0002] In the field of grain storage and processing, grain drying is a crucial step, as its effectiveness directly affects the quality and shelf life of the grain. Therefore, dryers are needed to dry the grains that need to be stored. However, some dryers use simple heating methods with uneven distribution of heating components, resulting in uneven heating of the grains, affecting the drying effect and reducing the quality of the grains. Some dryers also lack effective turning devices, causing the grains to pile up during the drying process, hindering air circulation and preventing the timely removal of moisture generated during drying. This prolongs the drying time, increases energy consumption, and, because the grains cannot be properly turned, there may be localized dampness after drying, making them prone to mold and spoilage during storage.

[0003] Therefore, it is necessary to provide a new type of grain dryer to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a new type of grain dryer, which has the advantages of using multi-point heating, uniform heating, and continuous blowing and turning of the grain during drying, thereby improving drying efficiency and effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel grain dryer includes a drying chamber. Several evenly distributed electric heating plates are fixedly connected to the bottom of the inner wall of the drying chamber. A wire mesh plate is fixedly connected inside the drying chamber, positioned above the electric heating plates. The mesh diameter of the wire mesh plate is smaller than the diameter of the grain particles. Air inlet slots are provided on both the left and right sides of the drying chamber, located below the wire mesh plate. An air intake fan is installed inside the air inlet slot. A movable frame is fitted onto the surface of the drying chamber. A nut seat is fixedly connected to the bottom of the movable frame. A lead screw is threaded into the nut seat. One end of the lead screw is rotatably connected to the bottom of the drying chamber via a bearing seat. A forward and reverse motor is fixedly connected to one side of the bottom of the drying chamber. The output end of the forward and reverse motor is fixedly connected to the other end of the lead screw. A follower frame is fixedly connected to the top of the inner wall of the movable frame. A drive motor is fixedly connected to the rear of the follower frame. A toggle roller frame is fixedly connected to the output end of the drive motor. The front end of the toggle roller frame is rotatably connected to the inner wall of the follower frame.

[0006] As a preferred embodiment of this utility model, the front and rear sides of the movable frame are fixedly connected to sliding sleeves, and the inside of the sliding sleeves is slidably connected to guide rods. The left and right ends of the guide rods are fixedly connected to the surface of the drying oven through fixed seats.

[0007] As a preferred embodiment of this utility model, an opening and closing door is hinged to the upper left side of the drying oven, and a round rod is fixedly connected to the top of the opening and closing door. A plug rod is slidably connected to the surface of the round rod through a connecting sleeve. A slot is provided on the left side of the front top of the drying oven. The surface of the bottom end of the plug rod is in contact with the inner wall of the slot. A compression spring is sleeved on the surface of the round rod. The bottom end of the compression spring is fixedly connected to the top of the connecting sleeve, and the top end of the compression spring is fixedly connected to the top of the round rod.

[0008] As a preferred embodiment of this invention, a detachable protective frame is fixedly connected to the surface of the air intake slot, and a protective net is fixedly connected inside the protective frame.

[0009] As a preferred embodiment of this utility model, the drying oven has cleaning and maintenance ports on the lower part of both the front and back sides, and the surfaces of the cleaning and maintenance ports are fixedly connected with detachable heat-insulating and sealing covers.

[0010] As a preferred embodiment of this invention, the inner wall of the drying oven is fixedly connected to a heat insulation layer, and the surface of the heat insulation layer is provided with an anti-stick coating.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes evenly distributed electric heating plates on the bottom of the inner wall of the drying chamber to provide relatively uniform heat to the grain inside, improving the drying effect and grain quality. The wire mesh plate ensures that the grain is positioned appropriately above the electric heating plates, and its mesh diameter is smaller than the grain particle diameter, preventing grain from falling onto the electric heating plates and causing damage or affecting the heating effect. The design of the air inlet slot and air inlet fan allows air to circulate within the drying chamber, promptly expelling moisture generated during the drying process. The coordination of the moving frame, nut seat, lead screw, and forward / reverse motor allows the follower frame to move back and forth within the drying chamber. The drive motor and agitator roller frame within the follower frame can turn the grain, ensuring full contact between the grain and hot air, preventing grain accumulation that could lead to poor air circulation, reducing localized dampness, and preventing the grain from molding and deteriorating during storage.

[0012] 2. This utility model provides a stable guiding effect for the movement of the moving frame by setting up a sliding sleeve and a guide rod. When the forward and reverse motor drives the lead screw to rotate, causing the nut seat to move the moving frame, the sliding sleeve slides on the guide rod, ensuring the smoothness and accuracy of the moving frame's movement. This helps the moving frame to move more stably back and forth in the drying chamber, thereby enabling the agitator roller frame to more accurately turn the grain, further improving the uniformity of grain drying, avoiding the impact of the moving frame shaking on the drying effect, and ensuring the stable operation and good performance of the new grain dryer.

[0015] 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.

[0016] like Figures 1 to 4As shown, this utility model provides a novel grain dryer, including a drying chamber 1. Several evenly distributed electric heating plates 2 are fixedly connected to the bottom of the inner wall of the drying chamber 1. A wire mesh plate 3, located above the electric heating plates 2, is fixedly connected inside the drying chamber 1. The mesh diameter of the wire mesh plate 3 is smaller than the diameter of the grain particles. Air inlet slots are provided on both the left and right sides of the drying chamber 1, located below the wire mesh plate 3. An air intake fan 4 is installed inside the air inlet slot. A movable frame 5 is fitted onto the surface of the drying chamber 1. A nut seat 6 is fixedly connected to the bottom of the movable frame 5. A lead screw 7 is threaded into the nut seat 6. A protective cover (not shown for ease of display) is provided on the surface of the lead screw 7. One end of the lead screw 7 is rotatably connected to the bottom of the drying chamber 1 via a bearing seat. A forward and reverse motor 8 is fixedly connected to one side of the bottom of the drying chamber 1. The output end of the forward and reverse motor 8 is connected to the lead screw 7. The other end is fixedly connected by a coupling. A follower frame 9 is fixedly connected to the top of the inner wall of the moving frame 5. The front and rear sides of the follower frame 9 are in sliding contact with the inner wall of the drying chamber 1. A drive motor 10 is fixedly connected to the rear of the follower frame 9. The output end of the drive motor 10 is fixedly connected to a roller frame 11 through a coupling. The front end of the roller frame 11 is rotatably connected to the inner wall of the follower frame 9 through a bearing seat. The radius of the roller frame 11 is the same as the distance from the axis of the roller frame 11 to the top of the wire mesh plate 3. A temperature sensor is provided on the surface of the wire mesh plate 3. A control system box is provided on the surface of the drying chamber 1. The control system box is electrically connected to the temperature sensor, the electric heating plate 2, the air intake fan 4, the forward and reverse motor 8 and the drive motor 10 respectively. It can intelligently control the electric heating plate 2, the air intake fan 4 and other equipment according to the actual situation of grain drying, thereby improving drying efficiency and accuracy.

[0017] refer to Figure 1 The front and rear sides of the movable frame 5 are fixedly connected with sliding sleeves 12. The inside of the sliding sleeves 12 is slidably connected with guide rods 13. The left and right ends of the guide rods 13 are fixedly connected to the surface of the drying oven 1 through fixed seats.

[0018] As a technical optimization of this utility model, by setting the cooperation between the sliding sleeve 12 and the guide rod 13, a stable guiding effect is provided for the movement of the moving frame 5. When the forward and reverse motor 8 drives the lead screw 7 to rotate, causing the nut seat 6 to move the moving frame 5, the sliding sleeve 12 slides on the guide rod 13, ensuring the smoothness and accuracy of the movement of the moving frame 5. This helps the follower frame 9 to move more stably back and forth in the drying chamber 1, thereby enabling the agitator roller frame 11 to more accurately turn the grain, further improving the uniformity of grain drying, avoiding the impact of the shaking of the moving frame 5 on the drying effect, and ensuring the stable operation and good performance of the new grain dryer.

[0019] refer to Figure 4A hinged door 14 is mounted on the upper left side of the drying oven 1. A round rod 15 is fixedly connected to the top of the door 14. A plug rod 16 is slidably connected to the surface of the round rod 15 through a connecting sleeve. A slot is provided on the left side of the top front of the drying oven 1. The bottom surface of the plug rod 16 is in contact with the inner wall of the slot. A compression spring 17 is fitted on the surface of the round rod 15. The bottom end of the compression spring 17 is fixedly connected to the top of the connecting sleeve, and the top end of the compression spring 17 is fixedly connected to the top of the round rod 15.

[0020] As a technical optimization of this utility model, the design of the opening and closing door 14 facilitates the addition or removal of grain into the drying box 1; the cooperation of the round rod 15, the insert rod 16, the slot, and the compression spring 17 ensures that the opening and closing door 14 can be securely closed. When it is necessary to open the opening and closing door 14, pull the insert rod 16 upward to disengage it from the slot, and it can be opened easily; when closing, release the insert rod 16, and under the action of the compression spring 17, the insert rod 16 inserts into the slot, ensuring that the opening and closing door 14 is tightly closed.

[0021] refer to Figure 1 The surface of the air intake slot is fixedly connected to a detachable protective frame 18 by bolts, and a protective net is fixedly connected inside the protective frame 18.

[0022] As a technical optimization of this utility model, by setting a detachable protective frame 18 and a protective net on the surface of the air inlet slot, it is possible to prevent external debris, dust and other objects from entering the drying chamber 1 with the airflow. The protective net can filter out larger impurities, preventing them from damaging the air intake fan 4 or affecting air circulation. The detachable design of the protective frame 18 makes it convenient to clean or replace the protective net, ensuring that the air intake effect of the air inlet slot is always good, maintaining the normal air circulation in the drying chamber 1, thereby ensuring the smooth progress of the grain drying process and the stability of the drying effect.

[0023] refer to Figure 1 The drying oven 1 has cleaning and maintenance ports on the lower front and back sides. The surfaces of the cleaning and maintenance ports are fixed with removable heat-insulating and sealing covers 19 by bolts.

[0024] As a technical optimization of this utility model, the installation of the cleaning and maintenance port and the heat-insulating sealing cover 19 facilitates the maintenance and cleaning of the dryer. After the dryer has been used for a period of time, some impurities or dust may accumulate at the bottom of the drying chamber 1. By opening the heat-insulating sealing cover 19, the inside of the drying chamber 1 can be easily cleaned, ensuring the hygiene and normal operation of the dryer. At the same time, the heat insulation performance of the heat-insulating sealing cover 19 can reduce heat loss, improve energy utilization efficiency, and reduce drying costs. In addition, when a fault occurs inside the dryer, it can also be repaired through the cleaning and maintenance port, shortening the repair time and reducing the impact on grain drying.

[0025] refer to Figure 3The inner wall of the drying oven 1 is fixedly connected with a heat insulation layer 20, and the surface of the heat insulation layer 20 is provided with an anti-stick coating.

[0026] As a technical optimization of this utility model, by setting the heat insulation layer 20, heat loss during the drying process can be effectively reduced, energy utilization efficiency can be improved, and energy consumption and drying costs can be reduced. The anti-stick coating on the surface of the heat insulation layer 20 can prevent the grain from sticking to the inner wall of the drying chamber 1 during the drying process, thus avoiding grain waste and contamination of the inner wall of the drying chamber 1.

[0027] The working principle and usage process of this utility model are as follows: During use, grain is placed onto the wire mesh plate 3 inside the drying chamber 1 from above. The equipment is then started, and the electric heating plate 2 at the bottom of the inner wall of the drying chamber 1 begins operation. Because the electric heating plate 2 is evenly distributed, it provides uniform heat to the grain. Simultaneously, the air intake fan 4 in the air intake slot is turned on, allowing air to enter the drying chamber 1 from the air intake slot. The speed of the air intake fan 4 is controlled during air intake to prevent excessive airflow that could cause the grain to overflow from the top of the drying chamber 1. The air circulates within the chamber, promptly removing moisture generated during the grain drying process. The forward and reverse motor 8 drives the lead screw 7 to rotate, which in turn moves the nut seat 6. The frame 5 moves back and forth, and the sliding sleeves 12 on both sides of the moving frame 5 slide on the guide rod 13 to ensure smooth movement. The moving frame 5 drives the follower frame 9 to move back and forth in the drying chamber 1. The drive motor 10 in the follower frame 9 drives the agitator roller frame 11 to rotate, turning the grain on the wire mesh plate 3 so that the grain can fully contact the hot air and speed up the drying process. The temperature sensor monitors the temperature of the surface of the wire mesh plate 3 in real time and transmits the data to the control system box. The control system box intelligently controls the working status of the electric heating plate 2, the air intake fan 4, the forward and reverse motor 8 and the drive motor 10 according to the preset parameters to ensure the accuracy and efficiency of the drying process.
