Description

Technical Field

[0001] This utility model relates to the field of rice drying and spreading technology, and in particular to a rice drying and spreading device. Background Technology

[0002] After harvesting, rice needs to be dried in the sun to effectively prevent it from becoming moldy during storage.

[0003] The existing rice drying and spreading methods are cumbersome and inefficient: the bagged rice must be poured out one by one on the drying ground, and then the rice must be pushed and pulled repeatedly with a rake to spread it evenly. Whether it is pouring the rice, spreading it with a rake, or collecting it in the morning and evening, the operators need to bend over continuously. The long-term repetitive bending and exertion will put a heavy burden on the waist and easily cause occupational injuries such as lumbar muscle strain. Utility Model Content

[0004] The purpose of this utility model is to provide a rice drying and spreading device to solve the problems mentioned above in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rice drying and spreading device, comprising a U-shaped base, wherein a rotating device is provided on the bottom surface of the U-shaped base, the rotating device comprising a motor fixedly installed at the bottom of the U-shaped base, a support frame fixedly installed at the output end of the motor via a coupling, and cylinders fixedly installed on the bottom surface of the vertical ends of the support frame.

[0006] Preferably, strip plates are fixedly installed on both outer wall surfaces of the cylinder, and grooves are formed on the surfaces of both strip plates, with a paving plate slidably connected inside each groove.

[0007] Preferably, a tie rod is fixedly installed on one side surface of the paving slab, and the end of the tie rod away from the paving slab passes through the strip plate and is fixedly installed with a tie plate.

[0008] Preferably, a PLC controller is fixedly installed on the side of the vertical end of one side of the U-shaped seat, and the PLC controller is electrically connected to the motor.

[0009] Preferably, a rotating shaft is rotatably connected between the inner walls of the two vertical ends of the U-shaped seat, a rotating ring is fixedly installed on the outer wall surface of the rotating shaft, and a hand-holding rod is fixedly installed on the outer wall surface of the rotating ring.

[0010] The effects achieved by the above components are as follows:

[0011] Preferably, the top surface of the cylinder is provided with an adjustment device, the adjustment device including a strip groove formed on the top surface of the cylinder, a slide rod fixedly installed between the inner walls of the two sides of the strip groove, and two sliding plates slidably connected to the outer wall surface of the slide rod.

[0012] Preferably, each of the two slide plates has a plug rod fixedly installed on its surface, and the outer wall surface of each of the two pull rods has a plurality of plug holes that match the plug rods evenly.

[0013] Preferably, vertical grooves are formed on the inner wall surfaces of both vertical ends of the support frame, and a horizontal bar is slidably connected between the two vertical grooves. A hinge plate is hinged to the top surface of the slide plate, and the end of the hinge plate away from the slide plate is hinged to the horizontal bar.

[0014] Preferably, two electric telescopic rods are fixedly installed on the top surface of the support frame, and the output ends of the two electric telescopic rods are fixedly connected to the crossbar plate. The PLC controller and the electric telescopic rods are electrically connected.

[0015] The aforementioned components achieve the following effects: through electric control and a precise limiting structure, flexible adaptation and stable fixing of the paving thickness are realized, overcoming the limitation of traditional devices that cannot adjust the thickness. First, by using the electric telescopic rod to drive the crossbar, hinge plate, and sliding plate in linkage, the limit of the insert rod on the pull rod can be quickly released. The operator can then adjust the height of the paving board by pulling the plate, easily adapting to different drying needs, such as thin paving on sunny days to speed up drying, and thick paving on rainy days to reduce rainwater erosion. No parts need to be replaced, making it highly adaptable.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] In this invention, a rotating device is incorporated, enabling motor-driven multi-component linkage, thus completely solving the core problems of low efficiency and high labor intensity associated with traditional manual paving. Firstly, the motor drives the support frame, cylinder, and paving board to rotate synchronously, replacing the manual operation of repeatedly pushing and pulling with a rake. No multiple people are needed; only one person can complete the paving of the drying yard, significantly reducing manpower input. Secondly, the rotating paving board evenly sweeps the piled rice to both sides, preventing uneven rice accumulation or uneven thickness caused by uneven force during manual operation, thus improving the uniformity of drying. Simultaneously, the special structural design of the paving board reduces rice splashing, lowering grain loss. Attached Figure Description

The cylinder 23 has a storage cavity located in the middle along the axial direction, 750mm from each end, ensuring balanced force during device movement. The storage cavity is sized to fit the universal casters, and the universal casters are mounted inside the storage cavity via a metal fixing bracket. A rubber sealing ring is embedded at the opening of the storage cavity to prevent rice grains from entering.

[0025] Reference Figure 2-4As shown in this embodiment: the top surface of the cylinder 23 is provided with an adjustment device 3. The adjustment device 3 includes a strip groove 31 formed on the top surface of the cylinder 23. A slide rod 32 is fixedly installed between the inner walls of the two sides of the strip groove 31. Two slide plates 33 are slidably connected to the outer wall surface of the slide rod 32. Insert rods 34 are fixedly installed on the surface of each of the two slide plates 33. Multiple insertion holes 35 matching the insert rods 34 are evenly formed on the outer wall surface of each of the two pull rods 27. Vertical grooves 36 are formed on the inner wall surface of the vertical ends on both sides of the support frame 22. A horizontal strip plate 37 is slidably connected between the two vertical grooves 36. A hinge plate 38 is hinged to the top surface of the slide plate 33. The end of plate 38 away from slide plate 33 is hinged to crossbar plate 37. Two electric telescopic rods 39 are fixedly installed on the top surface of support frame 22. The output ends of the two electric telescopic rods 39 are fixedly connected to crossbar plate 37. PLC controller 29 is electrically connected to electric telescopic rods 39. The hole spacing of the socket 35 is 10mm, which is suitable for thickness adjustment from 5-30mm. Each 10mm adjustment corresponds to one socket 35. The hinge plate 38 is made of high-strength nylon material with bending strength ≥80MPa. The electric telescopic rod 39 is model DTZ-50, with power of 0.2kW, stroke of 80mm, thrust ≥30N, and positioning error ≤0.5mm.

[0026] Working Principle: When using this device, first check the status of each component: confirm that the motor 21 operates without abnormal noise after being powered on, the overload protection module triggers normally, the electric telescopic rod 39 extends and retracts smoothly without jamming, the insertion rod 34 and the insertion hole 35 fit tightly without looseness, and the PLC controller 29 and the wireless remote control are successfully paired with a signal delay ≤0.3s; at the same time, check the universal rollers in the storage cavity of the cylinder 23 to ensure that the rollers rotate flexibly, the rubber sealing ring of the storage cavity opening is intact to prevent rice particles from entering and jamming the rollers, and clean the residual rice debris on the surface of the cylinder 23 and the paving plate 26 to avoid affecting the paving effect. After the inspection is completed, the operator first holds the long rod 6 and pushes the device to the edge of the drying field, so that the bottom of the cylinder 23 is close to the pile of rice to be paved, ensuring that the paving plate 26 can contact the rice during subsequent rotation. Then, send the "adjust and start" command through the PLC controller 29 or the wireless remote control, and the two electric telescopic rods 39 start and extend synchronously. The horizontal strip 37 slides upward along the vertical groove 36 of the support frame 22. When the horizontal strip 37 moves, the hinge plate 38 is pulled, causing the two sliding plates 33 to slide towards each other along the sliding rod 32 in the groove 31 of the cylinder 23. During the sliding of the sliding plates 33, the insert rod 34 on the surface is simultaneously disengaged from the insertion hole 35 on the pull rod 27, releasing the limit on the pull rod 27. Then, holding the pull plate 28, according to the drying requirements, the plate is laid thinly on sunny days and thickly on rainy days. The pull rod 27 is pulled up and down, and the pull rod 27 causes the paving plate 26 to slide along the groove 25 of the strip plate 24 until the distance between the paving plate 26 and the ground reaches the target thickness. After the thickness is determined, a "stop adjustment" command is sent via remote control. The electric telescopic rod 39 shortens and resets, causing the horizontal strip 37 to move downward. The hinge plate 38 pushes the sliding plate 33 back to the initial position, and the insert rod 34 is reinserted into the corresponding insertion hole 35 of the pull rod 27, completing the position fixation of the paving plate 36 with a positioning accuracy of ±0.After adjusting the thickness to 5mm, first confirm that the universal rollers inside the cylinder 23's storage cavity slightly protrude from the outer wall of cylinder 23, ensuring that the cylinder 23's rotation is not affected and that it can stably contact the drying ground. Then, send a "spreading start" command via remote control, and motor 21 starts. Its output end drives support frame 22 to rotate at a constant speed via a coupling. Support frame 22 synchronously drives the bottom cylinder 23, strip plate 24, and spreading plate 26 to rotate at a speed of 45 r / min. Spreading plate 26, with its 20° surface inclination angle, can evenly sweep the piled rice to both sides, avoiding grain separation. After splashing, the operator holds the long rod 6 and pushes the device in a straight line along the drying field at a steady speed. The universal rollers roll on the ground with a pushing resistance of ≤8N, which reduces the intensity of manual pushing and does not interfere with the rotation of the cylinder 23; no need for repeated back and forth, improving work efficiency. During the spreading process, if the rice pile is too thick in some areas, such as exceeding the target thickness, the speed of the motor 21 can be reduced to 30r / min or the pushing speed can be slowed down by remote control. After the rice is spread evenly, the normal parameters can be restored; if the motor 21 is overloaded by ≥15N due to rice jamming, the built-in The overload protection module will automatically shut down the machine. After clearing obstacles, restart it. After the paving is completed, first send a "paving stop" command via remote control to shut down motor 21. Then, the operator pushes the device to a corner of the paving area. Clean the rice debris adhering to the surface of cylinder 23 and the groove 25 of paving plate 26 with a soft brush. Simultaneously check the storage cavity of cylinder 23—if any rice particles have entered, open the rubber sealing ring to clean them, preventing the universal rollers from getting stuck. Then, store the device in a dry, ventilated place to prevent the motor 21 and PLC controller 29 from getting damp. During weekly maintenance, lithium-based grease should be applied to the surface of slide bar 32 to reduce sliding friction of the slide plate. Check the bearings of the universal rollers for flexibility; if rotation is restricted, add a small amount of lubricating oil. If reuse is required, repeat the "thickness adjustment-paving operation" process described above. No recalibration of component parameters is necessary. Through this process, the device automatically levels the rice paddy using a rotating mechanism, flexibly controls the paving thickness with an adjusting device, and reduces manual labor intensity with the universal rollers. Only one person is needed to operate the entire process, effectively solving the problems of low efficiency and high labor intensity associated with traditional manual paving.
