Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a mobile grain cleaning and drying integrated machine. Background Technology

[0002] After harvest, grains typically contain high levels of moisture and impurities (such as chaff, straw, dust, and immature grains). If stored directly without treatment, they are highly susceptible to mold, sprouting, and pest infestation, resulting in significant post-harvest losses. Therefore, cleaning and drying are two crucial steps in post-harvest grain processing, playing a decisive role in ensuring food security, improving grain quality, and enhancing storage stability.

[0003] A search revealed patent CN212205454U, an agricultural drying and screening device. This device dries grain inside a drying drum. A turning motor drives a turning shaft to rotate, causing a turning rod to continuously rotate within the drum, constantly turning the grain and effectively preventing grain accumulation that could lead to incomplete drying, thus improving drying efficiency and ensuring drying quality. A blower fan blows air onto the falling grain, directing dust, stems, and other debris towards a dust suction hood. A vacuum cleaner then removes these debris through a suction pipe and hood, effectively cleaning the grain and ensuring its cleanliness. A support spring at the lower end of the guide plate cushions and guides the grain, facilitating subsequent screening. This mechanical drying and screening process effectively reduces labor intensity, increases drying and screening efficiency, and is unaffected by weather conditions, effectively guaranteeing grain quality.

[0004] Current integrated equipment first dries the grain, then sorts it using fans. However, during the process of transporting the grain from the drying unit to the sorting unit, the grain is rapidly poured down in one go by gravity. Although the grain output speed is fast, the airflow generated by the fans can only act on the surface of the grain flow and cannot penetrate to the core of the grain flow. As a result, impurities inside the grain cannot be effectively blown out, leading to low cleaning efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile grain cleaning and drying integrated machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile grain cleaning and drying integrated machine, including a machine body and a turning component for turning the grain during drying;

[0007] The material turning assembly has a discharge port at its bottom, and two discharge plates are installed in the discharge port. Both ends of the two discharge plates are fixedly installed with connecting shafts, and multiple connecting shafts are slidably installed in a slide groove, which is opened in the machine body.

[0008] The machine body is equipped with a dual-axis motor, and threaded rods are fixedly installed at both ends of the dual-axis motor. The outer walls of the two threaded rods are threaded with movable plates, and the two movable plates are connected to the connecting shaft.

[0009] As a further preferred embodiment of this technical solution, the connecting shaft and the moving plate are slidably connected.

[0010] As a further preferred embodiment of this technical solution, a diversion grid is provided below the discharge plate, and the diversion grid is slidably installed in the machine body via a moving component.

[0011] As a further preferred embodiment of this technical solution, the moving component includes a moving seat fixedly installed on both sides of the diversion grille, and a reciprocating screw is threadedly connected to each of the two moving seats, with a servo motor installed at one end of each of the two reciprocating screws.

[0012] As a further preferred embodiment of this technical solution, a rotating shaft is provided at the bottom of the discharge plate. The rotating shaft is rotatably installed inside the machine body. One end of the rotating shaft is connected to a reciprocating lead screw through a pulley set. A cam is fixedly installed on the outer wall of the rotating shaft.

[0013] This utility model provides a mobile grain cleaning and drying integrated machine, which has the following beneficial effects:

[0014] (1) This utility model controls the amount of grain discharged through two discharge plates. When working, the grain is first poured into the machine body and dried by the drying component inside the machine body. After drying, the two screw rods are driven to rotate by the dual-shaft motor. The rotation of the two screw rods drives the movement of the two moving plates. The movement of the two moving plates drives the movement of the connecting shaft. The movement of the two connecting shafts drives the movement of the two discharge plates, so that the two discharge plates move outward to open the discharge port and the grain is discharged downward for screening. The size of the discharge port is controlled by controlling the distance of the movement of the discharge plates, thereby ensuring that the grain forms a continuous, uniform and moderately thick "curtain", which makes it easier for the airflow to pass through and carry away impurities, thereby improving the processing efficiency of the grain.

[0015] (2) By setting up the moving component, the present invention drives the reciprocating screw to rotate through the servo motor during operation. The rotation of the reciprocating screw drives the moving seat to move back and forth. The movement of the moving seat drives the movement of the diversion grid, which breaks the static friction between the grain particles and the diversion grid, so that the grain cannot stay in any position for a long time, thereby fundamentally preventing adhesion and blockage, and ensuring the absolute continuity and stability of grain output.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, a mobile grain cleaning and drying integrated machine includes a machine body 1 and a turning component 2 for turning the grain during drying.

[0023] The material turning component 2 has a discharge port at its bottom. Two discharge plates 3 are installed in the discharge port. Connecting shafts 5 are fixedly installed at both ends of the two discharge plates 3. Multiple connecting shafts 5 are slidably installed in the slide groove 6, which is opened in the machine body 1.

[0024] The machine body 1 is equipped with a dual-axis motor 9. Both ends of the dual-axis motor 9 are fixedly installed with threaded rods 8. The outer walls of the two threaded rods 8 are threaded with movable plates 7. Both movable plates 7 are connected to the connecting shaft 5.

[0025] The existing patent CN212205454U discloses an agricultural drying and screening device. This patent discloses the body 1, turning component 2, drying unit and sorting unit proposed in this application. The technical means will not be described in detail here.

[0026] The threads on the outer walls of the two threaded rods 8 are set in opposite directions to allow the two discharge plates 3 to move relative to each other;

[0027] During operation, the grain is first poured into the machine body 1 and dried by the drying components inside the machine body 1. After drying, the two threaded rods 8 are driven to rotate by the dual-shaft motor 9. The rotation of the two threaded rods 8 drives the two moving plates 7 to move. The movement of the two moving plates 7 drives the movement of the connecting shaft 5. The movement of the two connecting shafts 5 drives the two discharge plates 3 to move, so that the two discharge plates 3 move outward to open the discharge port and the grain is discharged downward for screening.

[0028] By controlling the distance the discharge plate 3 moves, the size of the discharge port can be controlled, thereby ensuring that the grain forms a continuous, uniform, and moderately thick "curtain," making it easier for airflow to pass through and carry away impurities, thus improving the processing efficiency of the grain.

[0029] like Figure 4 As shown, the connecting shaft 5 and the movable plate 7 are slidably connected.

[0030] like Figures 1 to 4 As shown, a diversion grid 4 is provided below the discharge plate 3, and the diversion grid 4 is slidably installed inside the machine body 1 via a moving component.

[0031] When the grain is discharged from the drying unit, it comes into contact with the diversion grid 4, which evenly disperses the grain instead of concentrating it into a single stream. This divides the grain into multiple parallel, fine grain streams, resulting in more thorough removal of impurities and further improving the cleaning effect.

[0032] like Figures 1 to 4 As shown, the moving assembly includes moving seats 11 fixedly installed on both sides of the diversion grille 4. Each of the two moving seats 11 is threadedly connected to a reciprocating screw 12, and a servo motor 13 is installed at one end of each of the two reciprocating screws 12.

[0033] During operation, the servo motor 13 drives the reciprocating screw 12 to rotate. The rotation of the reciprocating screw 12 drives the moving seat 11 to move back and forth. The movement of the moving seat 11 drives the diversion grid 4 to move, breaking the static friction between the grain particles and the diversion grid 4, so that the grain cannot stay in any position for a long time, thereby fundamentally preventing adhesion and blockage, and ensuring the absolute continuity and stability of grain output.

[0034] Furthermore, the diversion grid 4 not only divides the grain flow but also spreads the grain laterally on the surface, ensuring that the grain falls evenly across the entire width of the diversion grid 4. This achieves secondary fine homogenization of the grain discharge curtain in terms of width and density, with a uniformity far exceeding that of the static diversion grid 4, thus realizing "secondary homogenization".

[0035] like Figures 1 to 4 As shown, a rotating shaft 14 is provided at the bottom of the discharge plate 3. The rotating shaft 14 is rotatably installed inside the machine body 1. One end of the rotating shaft 14 is connected to the reciprocating screw 12 through the pulley set 16. A cam 15 is fixedly installed on the outer wall of the rotating shaft 14.

[0036] During operation, the reciprocating screw 12 rotates, driving the rotating shaft 14 to rotate via the pulley assembly 16. The rotation of the rotating shaft 14 drives the cam 15 to rotate, causing the cam 15 to intermittently strike the bottom of the drying cylinder to assist in material discharge. This prevents the grain from easily forming a stable "arch" or "bridge" support structure above the outlet due to friction and interlocking forces between particles, which could interrupt the flow, i.e., "arching." The striking action of the cam 15 generates an impact force that directly disrupts the mechanical balance of the arch foot or bridge pier, allowing the grain to resume its gravity-driven flow.

[0037] Furthermore, the vibration generated by the tapping causes slight elastic deformation and acceleration changes in the cylinder wall, which significantly reduces the adhesion between the grain particles and the wall surface, causing the adhered grain to fall off, improving the cleanliness of the discharge, and reducing the risk of batch mixing and mold growth.

[0038] This utility model provides a mobile grain cleaning and drying integrated machine, the specific working principle of which is as follows:

[0039] During operation, the grain is first poured into the machine body 1 and dried by the drying components inside the machine body 1. After drying, the two threaded rods 8 are driven to rotate by the dual-shaft motor 9. The rotation of the two threaded rods 8 drives the two moving plates 7 to move. The movement of the two moving plates 7 drives the movement of the connecting shaft 5. The movement of the two connecting shafts 5 drives the two discharge plates 3 to move, so that the two discharge plates 3 move outward to open the discharge port and the grain is discharged downward for screening.

[0040] When the grain is discharged from the drying unit, it comes into contact with the diversion grid 4, which disperses the grain evenly.

[0041] At the same time, the servo motor 13 drives the reciprocating screw 12 to rotate, the rotation of the reciprocating screw 12 drives the moving seat 11 to move back and forth, and the movement of the moving seat 11 drives the movement of the diversion grid 4, breaking the static friction between the grain particles and the diversion grid 4.

[0042] At the same time, when the reciprocating screw 12 rotates, it drives the rotating shaft 14 to rotate through the belt pulley group 16. The rotation of the rotating shaft 14 drives the rotation of the cam 15, causing the cam 15 to intermittently strike the bottom of the drying cylinder to assist in material discharge.

[0043] After being diverted by the diversion grid 4, the grain is sorted by the fan.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
