Description

Technical Field

[0001] The invention relates to the technical field of crop drying, and in particular to an agricultural crop drying device which is convenient for drying in layers. Background Art

[0002] Crops are the products of agriculture. There are many types of crops, they are rich in nutrients, and they can be processed into other foods. Generally speaking, crops need to be washed and dried before processing to ensure the quality of subsequent processing.

[0003] The invention patent with publication number CN113834305A discloses a covering type drying device for granular crops, including a drying tray A, a drying tray B, a drying tray C and four supporting legs. The covering type drying device for granular crops can perform layered drying when granular crops such as peanuts and soybeans are spread out for drying by arranging the drying tray A, the drying tray B and the drying tray C, thereby saving drying space.

[0017] Preferably, a plurality of fan blades are arranged inside the condenser via a connecting shaft, and the ends of the plurality of fan blades are respectively fixedly connected to a rotating block via a soft rope.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The present invention creates a negative pressure environment inside the column by arranging a negative pressure fan, so that the air outlet continuously inhales air. This continuous air flow can effectively accelerate the evaporation of moisture on the surface of crops. As the crops vibrate and slide down on the drying plate, they will continuously evaporate moisture into water vapor under the dual effects of sunlight heat and wind flow and be inhaled into the column. The water vapor is sent to the condenser through the negative pressure fan. The whole process ensures that the moisture in the crops evaporates rapidly, significantly improving the drying speed and efficiency. At the same time, bran, turf, shriveled grains and other debris will gradually approach the column, and finally be inhaled by the air outlet and introduced into the drop pipe, which can efficiently separate debris, reduce the impact of debris on crops, improve the cleanliness and quality of the crops finally harvested, and reduce the subsequent cleaning work, thereby enhancing the practicability of the equipment.

[0020] 2. The present invention provides devices such as collectors and photosensors, and the automatic adjustment of the collector enables it to be aligned in real time according to the position of the sun, ensuring that the collector is always at the optimal angle, maximizing the reception of sunlight and concentrating it on the drying mechanism, which can effectively improve the heat collection efficiency and reduce sunlight waste, thereby improving the energy utilization rate of the overall system, ensuring uniform heating during the drying process, shortening the drying time of crops, and improving the drying effect, avoiding local excessive or insufficient drying.

[0021] 3. The present invention utilizes a soft auger to continuously and smoothly transport the crops from the feed port to the collecting tank. The electromagnetic vibrator drives the column to vibrate continuously, which helps to prevent the crops from being piled up or accumulated at the bottom of the collecting tank, so that the crops can fall evenly onto the drying tray. The conical column can ensure the lighting of the crops on the drying tray. Under the action of the electromagnetic vibrator, the crops slide downward along the spiral path, so that the crops can be evenly distributed on the drying tray to avoid accumulation, and ensure that the crops are evenly exposed to sunlight, thereby enhancing the drying effect.

[0022] 4. The present invention recovers the water vapor generated during the evaporation process by setting a condenser to recycle the water for reuse, thereby avoiding the waste of water vapor. The recovered water can be used for irrigation or other purposes, further improving the energy saving and sustainability of the overall system. During the recovery process, the fan blades in the condenser rotate, causing the rotating block to knock on the tube wall of the condenser to make a sound. Combined with the sunlight reflected by the collector, it effectively drives away approaching birds, prevents birds from stealing crops, reduces bird droppings pollution, and improves the safety and hygiene of crops.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figures 1 to 8 A crop drying device for agricultural use that is convenient for drying crops in layers comprises a body 1. A walking mechanism 2 is arranged at the bottom of the body 1. The walking mechanism 2 comprises a crawler structure and a hydraulic system (this is the prior art). The crawler structure can provide better traction and stability on soft, slippery or uneven ground. The hydraulic system is used for leveling to ensure the stability of the body 1 during operation and to ensure that the equipment can still maintain a suitable working posture on uneven fields to avoid imbalance or instability of the equipment, thereby affecting agricultural operations. A control cabinet 3 is fixedly installed on the top of the body 1. The control cabinet 3 is used to control the operation of the entire equipment.

[0034] The top of the vehicle body 1 is provided with a drying mechanism 6, which includes a column 65 fixedly installed on the top of the vehicle body 1. The interior of the column 65 is hollow, and the inner diameter gradually decreases from bottom to top. The bottom of the column 65 is fixedly connected with a drop pipe 68, and the side wall of the drop pipe 68 is provided with a pendulum valve 69. A plurality of electromagnetic vibrators 610 are fixedly installed at the bottom of the outer wall of the column 65. The plurality of electromagnetic vibrators 610 are distributed in a circular array at the bottom of the column 65. The outer wall of the column 65 is fixedly installed with a plurality of electromagnetic vibrators 610. There is a spiral drying tray 66, and a baffle 661 is fixedly installed on the side of the drying tray 66 away from the column 65. The baffle 661 is used to prevent crops from falling from the drying tray 66. The top of the body 1 is fixedly installed with a frame 4, and an auger motor 52 is fixedly installed on the frame 4 (this is the prior art). The output end of the auger motor 52 is fixedly connected to a soft auger 5, and the end of the soft auger 5 away from the auger motor 52 is provided with a feed port 51. The bottom of the auger motor 52 is fixedly connected to a collecting The material tank 61, the collection tank 61 is located above the drying tray 66, and the bottom of the collection tank 61 corresponds to the drying tray 66. The crops are transported from the feed port 51 to the collection tank 61 through the soft auger 5, and the electromagnetic vibrator 610 is started to make the column 65 vibrate continuously, and the crops in the collection tank 61 gradually fall onto the drying tray 66. Under the action of vibration, the crops slowly slide down along the spiral path, so that the crops are gradually dispersed in the process of sliding down, and present a uniform laying state, which is conducive to uniform sunlight exposure. By setting the drying tray 66 as a spiral structure, a longer drying path can be provided in a limited space, which can improve the drying efficiency and reduce the waste of space. The spiral structure can also improve air circulation and promote the rapid drying of crops. The continuous vibration of the electromagnetic vibrator 610 keeps the crops in a flowing state and can ensure that the crops can be evenly distributed on the drying tray 66 to avoid accumulation, which helps to enhance the drying effect.

[0035] A large gear 7 is fixedly installed on the side wall of the column 65, and the large gear 7 is located below the drying tray 66. A discharge port 63 is provided at one end of the drying tray 66 close to the large gear 7. The discharge port 63 is fixedly connected to a discharge pipe 62. A humidity sensor 64 is fixedly installed on the side wall of the discharge pipe 62. The humidity sensor 64 monitors the humidity of the crops in real time and adjusts the vibration frequency of the electromagnetic vibrator 610, thereby controlling the crops to enter the discharge pipe 62 to prevent incomplete or over-drying of the crops and ensure the quality of the dried crops. A collector 8 is provided on the top of the vehicle body 1, and a photosensor 81 is fixedly installed on the top of the collector 8. A mounting plate 82 is installed on the bottom of the collector 8. The mounting plate 82 is located above the large gear 7 and is connected to the large gear 7 through an arc guide mechanism 71. The arc guide mechanism 71 includes The slide rail and the slider are arranged on the top of the large gear 7, and the slider is fixedly installed on the bottom of the mounting plate 82. The slider is slidably connected to the slide rail. A driving motor 83 is fixedly installed on the top of the mounting plate 82. A pinion 84 is fixedly connected to the output end of the driving motor 83. The pinion 84 meshes with the large gear 7. The photosensitive sensor 81 is used to detect the position of the sun and transmit a signal to the driving motor 83. The driving motor 83 is started to drive the pinion 84 to rotate. Under the action of the large gear 7 and the arc guide mechanism 71, the mounting plate 82 drives the collector 8 to rotate around the column 65, and adjusts the position of the collector 8 facing the sun. The collector 8 concentrates the sunlight on the drying mechanism 6 to maximize the use of solar energy, which not only improves energy efficiency, but also ensures that the most sufficient sunlight is obtained during the drying process, promoting more uniform drying.

[0036] The side wall of the column 65 is provided with a plurality of air vents 651, which are spirally distributed on the outer wall of the column 65. A negative pressure fan 67 is fixedly installed on the inner wall of the column 65. The negative pressure fan 67 is located above the air vents 651. The negative pressure fan 67 provides negative pressure to the inside of the column 65, so that the air vents 651 continuously inhale air. The continuous air flow can accelerate the evaporation of moisture in the crops and effectively improve the drying efficiency. When the crops are vibrating and sliding down, debris such as bran, grass, and shriveled grains will move away with the crops. Due to the action of wind flow, these debris are brought to the air outlet 651 and then enter the column 65. After drying, the drop pipe 68 discharges the debris entering the column 65. The air outlet 651 on the side wall of the column 65 is gradually farther away from the negative pressure fan 67 from top to bottom. Therefore, the further down the column 65 is, the smaller the air volume of the air outlet 651 is, to adapt to the crops whose moisture content is constantly decreasing and whose quality is gradually decreasing, to prevent the crops from being sucked away by the air outlet 651, and finally the crops slide down to the discharge port 63 and enter the storage box prepared in advance through the discharge pipe 62.

[0037] A condenser 9 is provided on the top of the column 65. One end of the condenser 9 away from the column 65 is fixedly connected with a rubber hose 91. The moisture in the crops evaporates continuously to form water vapor. The water vapor enters the column 65 through the air outlet 651 and is then sent into the condenser 9 by the negative pressure fan 67 for condensation and recovery. A mesh structure (not shown in the figure) is provided at the connection between the condenser 9 and the column 65. The mesh structure intercepts debris, thereby effectively recovering moisture and avoiding waste of water vapor, thereby improving the overall energy efficiency. The condensed water can be reused, for example, for irrigation or other purposes, further improving the energy saving and sustainability of the system. The condenser 9 is a slightly downwardly inclined reducer to prevent condensed water droplets from falling. The flow damages the negative pressure fan 67, and finally the condensed water is discharged from the rubber hose 91. The interior of the condenser 9 is provided with a plurality of fan blades 92 through a connecting shaft. The ends of the plurality of fan blades 92 are respectively fixedly connected with a rotating block 93 through a soft rope. The negative pressure fan 67 sends water vapor into the condenser 9. The fan blades 92 rotate due to the exhaust. The rotating block 93 continuously strikes the tube wall of the condenser 9 and makes a sound during the rotation of the fan blades 92. This sound works together with the sunlight reflected by the collector 8 to effectively drive away approaching birds. When approaching, the birds are stimulated by the sound and reflected light and usually stay away from the area, thereby preventing birds from stealing crops and reducing the pollution of crops by bird droppings, thereby protecting crops and reducing pollution.

[0038] In the present invention, the traveling mechanism 2 carries the vehicle body 1 to move, the crawler structure adapts to the agricultural environment, enhances the flexibility of the device, and can be leveled by the hydraulic structure in the traveling mechanism 2 to ensure the stability of the vehicle body 1. The equipment moves to the field to be dried, and the operation of each mechanism on the equipment is controlled by the control cabinet 3. The photosensitive sensor 81 detects the position of the sun and transmits a signal to the drive motor 83, and the drive motor 83 drives the small gear 84 to rotate. Under the meshing transmission of the small gear 84 and the large gear 7, the mounting plate 82 is guided by the arc guide mechanism 71 and carries the collector 8 to rotate around the drying mechanism 6 until it moves to the position where the collector 8 faces the sun and stops. The collector 8 concentrates the sunlight to The drying mechanism 6 is then used to transport the crops from the feed port 51 to the collecting tank 61 through the soft auger 5. The electromagnetic vibrator 610 causes the column 65 to vibrate continuously. Under the vibration, the crops in the collecting tank 61 fall onto the drying tray 66, and then slide down along the drying tray 66 spirally welded on the column 65. The conical column 65 ensures the lighting of the crops on the drying tray 66. The spirally layered drying tray 66 reduces the floor space, avoiding accidents caused by farmers drying crops on the road. The baffle 661 prevents the crops from sliding off the drying tray 66. A negative pressure fan 67 is provided on the top of the column 65. The negative pressure fan 67 provides negative pressure for the inside of the column 65. Under negative pressure, the circular spiral The air vents 651 evenly distributed on the column 65 continuously blow air into the column 65, providing continuous and rapid air flow for the drying tray 66, accelerating the evaporation of moisture in the crops and improving the drying efficiency. The crops vibrate and slide on the drying tray 66 and continuously turn over. Under the collected sunlight heat, the moisture in the crops continuously evaporates to form water vapor and enters the column 65 through the air vents 651, and then is sent to the condenser 9 by the negative pressure fan 67. Under the continuous air intake, the bran, grass, shrunken grains and other debris mixed in the crops vibrate and slide down while approaching the column 65, and are finally sucked into the drop pipe 68 by the air vents 651 from top to bottom due to the negative pressure fan 67. 67, the wind volume gradually weakens at different distances to adapt to the crops whose moisture content is constantly decreasing and whose quality is gradually decreasing, to prevent the crops from being sucked away by the air outlet 651, and finally the crops slide down to the discharge port 63, and fall into the storage box prepared in advance through the discharge pipe 62, and the drying is completed. The discharge pipe 62 is provided with a humidity sensor 64, which monitors the humidity of the crops passing through in real time and regulates the vibration frequency of the electromagnetic vibrator 610 to prevent incomplete or over-drying of the crops and ensure the quality of the dried crops. The collector 8 also moves continuously according to the position of the sun to ensure that the drying mechanism 6 has sufficient sunlight. After the drying is completed, the pendulum valve 69 opens to discharge the debris in the drop pipe 68.

[0039] The negative pressure fan 67 sends water vapor into the condenser 9. The condenser 9 is a reducer that is slightly inclined downward to prevent condensed water droplets from flowing back and damaging the negative pressure fan 67. Finally, the condensed water enters the rubber hose 91 along the inclined pipeline and is discharged. The fan blades 92 in the condenser 9 rotate due to exhaust. The end of the fan blades 92 is connected to a rotating block 93 by a soft rope. As the fan blades 92 rotate, the rotating block 93 continuously hits the tube wall of the condenser 9 to make a sound, which together with the sunlight continuously reflected by the collector 8 drives away approaching birds, prevents birds from stealing crops and reduces bird droppings from polluting crops.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
