Description

Technical Field

[0001] This application relates to the technical field of grain drying, and in particular to a diversion mechanism for a grain drying device. Background Technology

[0002] In the current grain drying industry, efficient and low-loss material handling is a key factor in ensuring the quality of the finished product.

[0003] Traditional drying equipment often lacks a protective structure at the tail rollers of the elevator, allowing grains to easily fall onto them during transport. This results in a significant increase in the broken rice rate. Although some equipment is equipped with a baffle to prevent grains from directly impacting the rollers, a dead zone for material accumulation can easily form between the baffle and the conveyor belt. Under the pressure of the elevator's rear wall and the rubber belt, the grains exacerbate the peeling of rice husks and the crushing of brown rice, further worsening the broken rice rate.

[0004] Regarding the aforementioned technologies, the applicant believes that they have drawbacks such as high broken rice rate and easy grain accumulation. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a diversion mechanism for a grain drying device.

[0008] By adopting the above technical solution, the rollers are fixedly connected to the drive mechanism and rotate under the drive mechanism to provide power to the conveying mechanism. The drive mechanism ensures that the grains are conveyed at a set speed. The conveying mechanism is used to carry and transport the grains from one end of the dryer to another working area, realizing continuous material transmission. The addition of a diversion mechanism is to reduce the negative impact caused by grains falling from the conveying device during transportation. The rubber scraper is to prevent grains from getting stuck between the conveying plate and the diversion device, preventing it from affecting the normal operation of the conveying device. The baffle plate is set to prevent grains from falling into the working position of the rollers, causing excessive broken rice.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a diversion mechanism for a grain drying device. (Refer to...) Figure 1-4The diversion mechanism 5 achieves its function through the stable connection of multiple components. The four corners of the baffle plate 51 are connected to the frame 1 through adjusting screws 8. The lower end of each adjusting screw 8 is fixed to the frame 1 with bolts. After the upper end of the adjusting screw 8 passes through the corresponding hole in the baffle plate 51, the tilt angle and height of the baffle plate 51 can be adjusted by tightening and rotating the nut. At the opening below the diversion plate 52 installed on the baffle plate 41, the electric rotating rod 7 is fixedly connected to the bottom of the frame. The output end of the electric rotating rod 7 is fixed to the central shaft of the diversion plate 52 through a key connection. To ensure stable power transmission and fix the angle through a self-locking device, the rubber scraper 53 is fixed to the pre-set mounting grooves on both sides of the diversion plate 52. The bottom of the rubber scraper 53 is in contact with one side of the conveyor plate 43. During operation, the grain transported by the conveying mechanism 4 is guided to the diversion plate 52 by the baffle plate 51. The electric rotating rod 7 adjusts the angle of the diversion plate 52 as needed to distribute the grain to different paths. The rubber scraper 53 cleans the side of the conveyor plate 43 simultaneously. The conveying mechanism 4 is tightly connected to the roller 2 and the frame 1 to provide stable conveying for diversion.

[0029] Rollers 2 are mounted on both sides of the frame 1 via bearings. Inner conveyor belts 41 are bonded to both sides of the outer surface of rollers 2 via a vulcanization process. The inner conveyor belts 41 and rollers 2 are tightly fitted together to achieve transmission. Conveyor plates 43 are fixed to the inner conveyor belts 41 and outer conveyor belts 42 at both ends via riveting, forming a rigid transmission plane. A support plate 421 at the bottom of the outer conveyor belt 42 is connected to the side of the frame 1 via a slot. The top of the support plate 421 is tightly fitted to the bottom of the conveyor plate 43 to prevent grain sagging. A maintenance door 12 is provided on one side of the frame, hinged to the frame via stainless steel hinges. A handle is installed on the other side of the maintenance door 12 for quick opening to clean accumulated materials or inspect components. The drive mechanism 3 consists of a motor 31 and a reducer. The system consists of 32 components, which are fixed to the mounting plate welded to the side of the frame 1 by bolts. The output shaft of the motor 31 and the input shaft of the reducer 32 are connected by a coupling to ensure smooth power transmission. The output shaft of the reducer 32 is fixed to the central shaft of the roller 3 by a flat key and a shaft end retaining ring, driving the roller 2 to rotate. The hopper 6 is fixed to one side of the frame 1 by welding. The hopper 6 is equipped with a guide ramp to facilitate the adjustment of the grain falling angle when loading grain. When the whole set of equipment is running, the drive mechanism 3 drives the conveying mechanism 4 to transport grain. The diversion mechanism 5 adjusts the angle as needed to meet the needs of cleaning and isolating fallen grain, preventing fallen grain from affecting the normal operation of the dryer. All components work together to ensure the efficient operation of the drying process.

[0030] The working principle of the diversion mechanism of the grain drying equipment in this application is as follows: Grain enters from the hopper 6, the motor 31 is powered on and runs, outputting high-speed power, which is transmitted to the reducer 32. The reducer 32 reduces the speed and increases the torque, and transmits the power stably to the central shaft of the roller 2, driving the roller 2 to rotate at a set speed. The inner conveyor belt 41 on the outer surface of the roller 2 rotates synchronously with the roller, driving the conveyor plates 43 at both ends and the outer conveyor belt 42 to circulate. The pallet 421 is connected to the frame 1 and fits against the bottom of the conveyor plate 43 to prevent the conveyor belt from sagging and piling up due to the weight of the grain, ensuring that the grain is transported smoothly from one end of the equipment to another working area. When the grain is transported by the conveyor plate 43 to the top of the baffle plate 51, some grain will fall. The baffle plate 51 prevents grains from falling into the roller 2, which would result in an excessively high rate of broken grains. The diverter plate 52 prevents grains from accumulating on the rubber scraper 53. Operators can adjust the angle and height of the baffle plate 51 by rotating the nut of the adjusting screw 8 to adapt to the flowability of different grains and the drying process requirements. The electric rotary rod 7 is started according to manual instructions, driving the diverter plate 52 to rotate and using a self-locking device to fix it to the target angle, diverting the grains to the required diversion path. The rubber scraper 53 is close to one side of the conveyor plate 43, simultaneously scraping off the stuck grains to avoid material accumulation or jamming. The detachable connection of the pallet 421 and the hinge design of the maintenance door 12 facilitate quick disassembly and cleaning of the accumulated material under the conveyor belt or maintenance of internal components.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
