Description

Technical Field

[0001] The invention relates to the technical field of grain leveling equipment, and in particular to a composite rotary blade device integrating grain raking and grain leveling. Background Art

[0002] The grain leveling operation in a granary generally involves a large workload and a poor working environment. Long hours of work in the granary are very harmful to the workers' health. When the grain leveling operation in a granary relies solely on manual work, there are problems such as low efficiency, poor work results, and long labor time. With the development of agricultural machinery, machines for leveling the grain surface of granaries have also appeared on the market, but the restrictions on the conditions of use are also particularly obvious. Fully automatic machines for leveling grain surfaces in granaries can be roughly divided into two types.

[0003] The first is a truss-type grain leveling mechanism: this mechanism can drive the actuator to move through the prefabricated truss structure in the silo. This mechanism has better flexibility and much higher work efficiency than the traditional method. In order to meet the technical requirements of grain leveling, the lower end of the truss structure usually uses rotating blades to level the grain surface, which is more effective for silos with densely uneven grain surfaces and no large grain piles. However, when encountering a large grain pile, the truss-type grain leveling mechanism often needs to start from the top and slowly operate on the grain pile, which will reduce work efficiency and is more likely to damage the rotating blades of the grain leveling.

[0004] The second type is a crawler-type grain leveler: crawler-type automatic grain leveling equipment is a type of equipment that uses crawlers to walk on the grain surface and prefabricated grain guide baffles at the front end to level the grain surface. The transmission system of the crawler-type grain leveler is relatively complex and the working efficiency is not high, but it can work in any occasion. This type of leveler uses movable crawlers, which has made great progress in walking on the grain surface, but the disadvantages are also particularly obvious. The large mass of the machine body can easily lead to the lower limit of the grain surface, and the tilt of the machine body on the uneven walking plane is also a big problem. With the continuous development of science and technology, the design of the leveler has been greatly improved, and the problems of unstable walking function and inconvenient steering have also been solved. However, it is easy to see that these levelers all use crawler-type ground walking devices, and the defects of this device when walking on soft roads such as grain surfaces are also particularly obvious.

[0005] The above devices have obvious defects in design or operation, which will affect the flatness of the grain surface and it is difficult to achieve a mirror-like flatness. Summary of the invention

[0006] The main purpose of the present invention is to propose a composite rotary blade device that integrates grain raking and grain leveling, aiming to solve the problems that a truss-type grain distributor cannot efficiently handle large grain piles and that a crawler-type grain leveler is too heavy when walking on the grain surface and is prone to tilting when leveling grain. It has the functions of raking, spreading and leveling grain, thereby leveling the grain surface and improving the efficiency of grain leveling.

[0007] In order to achieve the above-mentioned purpose, the present invention proposes a composite rotary blade device for grain scraping and grain leveling, comprising:

[0008] The load-bearing rotating mechanism comprises a guide rail and a slide rail frame, wherein the guide rail is used to be installed on the top of the bunk house, and the slide rail frame is slidably connected to the guide rail so that the slide rail frame moves along the extension direction of the guide rail;

[0009] An auger rotary blade mechanism comprises a grain storage hopper, an auger outer cylinder, rotary blades, and an auger, wherein the grain storage hopper is connected to the slide rail frame, the auger outer cylinder is located between the grain storage hopper and the slide rail frame, and its lower end extends to the grain storage space inside the grain storage hopper, the auger is located inside the auger outer cylinder, and is rotatably arranged relative to the auger outer cylinder so that the grain in the grain storage hopper is lifted to the upper end outlet of the auger outer cylinder, the rotary blade is arranged on the outer side wall of the top end of the auger outer cylinder, and is rotatably arranged relative to the grain storage hopper so that the grain located at the upper end outlet of the auger outer cylinder is dispersed to different areas under the rotation of the rotary blade; and,

[0010] A belt posture variable mechanism includes a support plate, a connecting rod assembly, a rotating roller, an angle adjustment assembly, a belt, and a scraper. The support plate is arranged at the upper end opening of the grain storage hopper and is connected thereto. The connecting rod assembly includes four connecting rods that are arranged in a parallelogram and can be rotatably adjusted, one of which is connected to the support plate. The rotating roller is installed at the rotating fulcrums corresponding to the four connecting rods. The angle adjustment assembly is arranged at two rotating fulcrums opposite to each other in the up and down directions to adjust the relative distance between the two rotating fulcrums. The belt is located at the four transmission fulcrums and is slidably connected to the rotating roller. The scraper is installed on the belt.

[0011] In one embodiment, the belt posture variable mechanism further includes:

[0012] A transmission rotary motor is mounted on the support plate, and an output end of the transmission rotary motor is connected to the rotating roller so that the transmission roller drives the belt to rotate under the drive of the transmission rotary motor; and

[0013] An angle adjustment motor is installed on the support plate, and an output end of the motor is connected to the angle adjustment component to adjust the relative distance between the two rotation fulcrums.

[0014] In one embodiment, the four connecting rods include:

[0015] a fixing rod installed between the transmission rotating motor and the angle adjusting motor; and,

[0016] Three movable rods are rotatably connected to each other in sequence and are rotatably connected to the head and tail ends of the fixed rod to form a parallelogram arrangement.

[0017] In one embodiment, the angle adjustment assembly comprises:

[0018] A first adjusting rod, the head end of which is located at a rotation fulcrum of the fixing rod away from the transmission rotating motor and is transmission-connected to the output end of the angle adjusting motor so that the first adjusting rod can rotate under the drive of the angle adjusting motor; and

[0019] The second adjusting rod has its head end rotatably connected to the end of the first adjusting rod, and its tail end is located at another rotating fulcrum corresponding to the rotating fulcrum of the fixed rod away from the transmission rotating motor along the up and down direction, and is rotatably connected to the movable rod at the corresponding rotating fulcrum.

[0020] In one embodiment, the belt posture variable mechanism further includes:

[0021] The front shovel is installed at a rotation fulcrum far away from the support plate.

[0022] In one embodiment, the rotating load-bearing mechanism further comprises:

[0023] A driving rotating motor is installed on the upper side of the supporting plate;

[0024] a gear rack, mounted on the upper side of the support plate near the driving rotary motor; and

[0025] The transmission assembly is located in the gear frame and is used to transmit the kinetic energy of the driving rotary motor to the auger so that the auger can rotate relative to the auger outer cylinder.

[0026] In one embodiment, the transmission assembly comprises:

[0027] A drive motor gear, located in a transmission connection between the gear rack and the output end of the drive rotary motor;

[0028] a transmission gear located on the gear rack and meshing with the drive motor gear; and,

[0029] The upper end of the rotating central shaft is connected to the transmission gear, and the lower end of the rotating central shaft is connected to the auger.

[0030] In one embodiment, the auger blade mechanism further comprises:

[0031] An internally meshing large gear, arranged at the upper end of the auger;

[0032] A plurality of small gears are distributed at intervals along the radial direction of the internally meshing large gear and are meshed with the internally meshing large gear; and,

[0033] The driving gear is located on the central axis of the internally meshing large gear, and its outer side is meshed with the plurality of small gears and is drivingly connected with the rotating central shaft.

[0034] In one embodiment, the auger blade mechanism further comprises:

[0035] A grain cover is located above the rotating blades and is drivingly connected to the rotating central shaft; and

[0036] A connecting key is installed between the grain cloth cover and the driving gear, so that the grain cloth cover drives the driving gear to rotate through the connecting rod.

[0037] In one embodiment, the auger blade mechanism further comprises:

[0038] A positioning frame, located between the grain cloth cover and the driving gear, and having a clearance hole in the middle thereof for the rotation track of the connecting key, a peripheral side thereof is fixedly connected to the auger outer cylinder, and having a through hole corresponding to the pinion gear; and,

[0039] A pinion axle is coaxially arranged on one side of the plurality of pinions facing the positioning frame, and the pinion axle is inserted into the through hole and is rotatably connected to the positioning frame.

[0040] The technical solution of the present invention has at least two working modes, as shown below:

[0041] In the first method, the slide rail frame moves on the guide rail preset at the top of the flat warehouse, and the auger rotates relative to the outer cylinder of the auger to spirally lift the grain in the grain hopper to the rotary blade. The rotary blade rotates to redistribute the lifted grain. When the device moves to the uneven grain surface, if a large grain pile appears that requires multiple leveling or the leveling overcomes large resistance, the connecting rod assembly may deform accordingly, causing the belt to deform. When the belt is running, the belt tilts and lifts the grain to the grain hopper, and the grain stored in the grain hopper is lifted to the rotary blade by the auger. The collected grain is redistributed evenly on the grain surface with the help of the circular motion of the rotary blade.

[0042] The second method is when the grain surface only needs to be finely leveled or only a small part of the grain surface needs to be leveled. Similarly, the slide rail frame moves on the preset flat warehouse rail, but the load-bearing rotating mechanism and the auger blade mechanism do not work. The slide rail frame moves along the rail to drive the entire device to move toward the uneven grain surface. At this time, the belt works, making the belt rotate counterclockwise, and the scraper on the belt is used to level the grain surface.

[0043] According to the different heights of the grain piles encountered by the device, the connecting rod assembly can be controlled to deform to different degrees, so that the belt can be deformed to different degrees to adapt to shoveling grain piles of different heights. It solves the problem that the truss-type grain distributor cannot efficiently handle large grain piles and the crawler-type grain leveler is too heavy when walking on the grain surface and is easy to tilt when leveling grain. It has the functions of shoveling, distributing and leveling grain, making the grain surface flat and improving the efficiency of grain leveling. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] like Figure 1 As shown, the composite rotary blade 202 device 100 for grain scraping and grain leveling proposed by the present invention comprises a load-bearing rotary mechanism 1, an auger 205 rotary blade 202 mechanism 2, and a belt posture variable mechanism 3. The load-bearing rotating mechanism 1 includes a guide rail and a slide rail frame 101. The guide rail is used to be installed on the top of the bunk house. The slide rail frame 101 is slidably connected to the guide rail so that the slide rail frame 101 moves along the extension direction of the guide rail; the auger 205 and the rotary vane 202 mechanism 2 includes a grain storage hopper 201, an auger outer cylinder 204, a rotary vane 202, and an auger 205. The grain storage hopper 201 is connected to the slide rail frame 101. The auger outer cylinder 204 is located between the grain storage hopper 201 and the slide rail frame 101, and its lower end extends to the grain storage space inside the grain storage hopper 201. The auger 205 is located inside the auger outer cylinder 204 and is rotatably arranged relative to the auger outer cylinder 204 so that the grain in the grain storage hopper 201 is lifted to the upper end outlet of the auger outer cylinder 204. The rotary vane 202 is arranged on the outer side wall of the top end of the auger outer cylinder 204 and is relative to the grain storage hopper 20 1 is arranged to rotate so that the grain at the upper end outlet of the auger outer cylinder 204 is dispersed to different areas under the rotation of the rotary blade 202; the belt posture variable mechanism 3 includes a support plate, a connecting rod assembly 306, a rotating roller 305, an angle adjustment assembly 307, a belt, and a scraper 308. The support plate is arranged corresponding to the upper end opening of the grain storage hopper 201 and is connected thereto. The connecting rod assembly 306 includes four connecting rods arranged in a parallelogram and rotatable and adjustable, one of which is connected to the support plate. The rotating roller 305 is installed at the rotating fulcrums corresponding to the four connecting rods. The angle adjustment assembly 307 is arranged at two rotating fulcrums opposite to each other in the up-down direction to adjust the relative distance between the two rotating fulcrums. The belt is located at the four transmission fulcrums and is slidably connected to the rotating roller 305. The scraper 308 is installed on the belt.

[0065] like Fig. 9 and Fig.10As shown, the technical solution of the present invention has at least two working modes, as shown below:

[0066] In the first mode, the slide rail frame 101 moves on the guide rail preset at the top of the flat warehouse, and the auger 205 rotates relative to the auger outer cylinder 204 to spirally lift the grain in the grain storage hopper 201 to the rotary blade 202. The rotary blade 202 rotates to redistribute the lifted grain. When the device moves to an uneven grain surface, if a large grain pile appears that requires multiple leveling or leveling to overcome large resistance, the connecting rod assembly 306 may be deformed accordingly, causing the belt to deform. When the belt is running, the belt tilts and lifts the grain to the grain storage hopper 201, and the grain stored in the grain storage hopper 201 is lifted to the rotary blade 202 by the auger 205. The collected grain is redistributed evenly on the grain surface with the help of the circular motion of the rotary blade 202.

[0067] The second method is when the grain surface only needs to be finely leveled or only a small part of the grain surface needs to be leveled. Similarly, the slide rail frame 101 moves on the preset flat warehouse rail, but the load-bearing rotating mechanism 1 and the auger 205 blade 202 mechanism 2 do not work. The slide rail frame 101 moves along the rail to drive the entire device to move toward the uneven grain surface. At this time, the belt operates, causing the belt to make a counterclockwise rotation motion, and the scraper 308 on the belt is used to flatten the grain surface.

[0068] According to the different heights of the grain piles encountered by the device, the connecting rod assembly 306 can be controlled to deform to different degrees, so that the belt can be deformed to different degrees to adapt to shoveling grain piles of different heights. It solves the problem that the truss-type grain distributor cannot efficiently handle large grain piles and the crawler-type grain leveler is too heavy when walking on the grain surface and is easy to tilt when leveling grain. It has the functions of shoveling, distributing and leveling grain, realizes the leveling of the grain surface, and improves the efficiency of grain leveling.

[0069] like Figure 7 and Figure 8 As shown, in one embodiment, the belt posture variable mechanism 3 also includes a transmission rotation motor 304 and an angle adjustment motor 303: the transmission rotation motor 304 is installed on the support plate, and its output end is transmission-connected with the rotating roller 305, so that the transmission roller drives the belt to rotate under the drive of the transmission rotation motor 304; the angle adjustment motor 303 is installed on the support plate, and its output end is connected with the angle adjustment component 307 to adjust the relative distance between the two rotation fulcrums.

[0070] It is understandable that the transmission rotary motor 304 is firmly mounted on the support plate as the core source of driving force. Its output end is directly connected to the rotating roller 305. When the transmission rotary motor 304 starts working, it will directly transmit the rotational force to the rotating roller 305, thereby driving the belt to rotate in a preset direction. In this way, the movement of the belt can be accurately and efficiently controlled. The angle adjustment motor 303 is also installed on the support plate, parallel or adjacent to the transmission rotary motor 304, so as to jointly control the overall movement posture of the belt. Its output end is connected to the angle adjustment component 307. By controlling the operation of the angle adjustment motor 303, the relative distance between the two rotating fulcrums (i.e., the key points of belt support and rotation) can be accurately adjusted. In this way, the inclination angle of the belt can be changed so that the belt can adapt to different working requirements or environmental conditions.

[0071] In summary, the belt posture variable mechanism 3 not only realizes the continuous or intermittent transmission function of the belt by combining the synergistic effect of the transmission rotation motor 304 and the angle adjustment motor 303, but also gives the belt the ability to adjust its posture, greatly improving the flexibility and adaptability of the belt transmission system.

[0072] In one embodiment, the four connecting rods include a fixed rod 3061 and three movable rods 3062. The fixed rod 3061 is installed between the transmission rotation motor 304 and the angle adjustment motor 303. The three movable rods 3062 are rotationally connected in sequence and are rotationally connected to the head and tail ends of the fixed rod 3061 to form a parallelogram.

[0073] It is understandable that the fixed rod 3061 is firmly installed between the transmission rotating motor 304 and the angle adjustment motor 303. It can serve as the benchmark and fixed point of the entire connecting rod system to ensure that other movable rods 3062 can be stably moved and adjusted on its basis. Through the fixed rod 3061, the power of the transmission rotating motor 304 and the angle adjustment motor 303 can be stably transmitted to the parts that need to be adjusted. These three movable rods 3062 are connected to each other through rotational connection to form a flexible framework. They are also connected to the head and tail ends of the fixed rod 3061 by rotation, and the whole presents a parallelogram structure. This design allows the movable rod 3062 to maintain a relatively stable shape when subjected to external force or power, while allowing angle adjustment within a certain range in the plane.

[0074] The advantage of the parallelogram structure lies in its stability and flexibility. When one angle of the parallelogram changes, the other three angles will also change accordingly, but the shape of the entire structure remains unchanged (i.e. it always remains a parallelogram). This feature allows the mechanism to maintain overall stability and balance when adjusting the angle.

[0075] In one embodiment, the angle adjustment assembly 307 includes a first adjustment rod 3071 and a second adjustment rod 3072:

[0076] The first adjusting rod 3071, whose head end is located at the rotation fulcrum of the fixed rod 3061 away from the transmission rotating motor 304, and is transmission-connected to the output end of the angle adjustment motor 303, so that the first adjusting rod 3071 can rotate when driven by the angle adjustment motor 303; the second adjusting rod 3072, whose head end is rotationally connected to the end of the first adjusting rod 3071, and whose tail end is located at another rotation fulcrum corresponding to the rotation fulcrum of the fixed rod 3061 away from the transmission rotating motor 304 along the up and down directions, and is rotationally connected to the movable rod 3062 at the corresponding rotation fulcrum.

[0077] It is understandable that, under the drive of the angle adjustment motor 303, the first adjustment rod 3071 can rotate around the rotation fulcrum between the first adjustment rod 3071 and the fixed rod 3061, and the head end of the second adjustment rod 3072 is rotationally connected to the end of the first adjustment rod 3071, forming a joint that can rotate relatively. The tail end of the second adjustment rod 3072 is located at another rotation fulcrum corresponding to the rotation fulcrum of the fixed rod 3061 away from the transmission rotation motor 304, and is rotationally connected to the movable rod 3062 at this rotation fulcrum. This design enables the second adjustment rod 3072 to move with the rotation of the first adjustment rod 3071, and transmit the effect of angle adjustment by rotating the connection with the movable rod 3062. When the first adjustment rod 3071 rotates under the drive of the angle adjustment motor 303, the second adjustment rod 3072 will move accordingly and drive the movable rod 3062 connected thereto to adjust the angle. Since the movable rod 3062 and the fixed rod 3061 are also rotationally connected, the entire parallelogram mechanism can perform corresponding angle adjustments according to the relative position changes of the first adjustment rod 3071 and the second adjustment rod 3072 .

[0078] In one embodiment, the belt posture variable mechanism 3 further includes a front shovel 301 , and the front shovel 301 is installed at a rotation fulcrum away from the support plate.

[0079] It is understandable that the front shovel 301 is installed at a rotation fulcrum away from the support plate, that is, it is located at the front end of the belt posture variable mechanism 3. This position enables the front shovel 301 to effectively contact and collect grain, which is conducive to shoveling grain onto the belt and then transporting the material to the designated position through the movement of the belt.

[0080] It can be expanded that the front shovel 301 can be set to different shapes and sizes to adapt to different types of grains. At the same time, the front shovel 301 can be set to have a certain inclination angle so that the grains can slide onto the belt better.

[0081] like Figure 2As shown, in one embodiment, the rotary load-bearing mechanism further includes a driving rotary motor 103, a gear frame 102, and a transmission assembly 105. The driving rotary motor 103 is mounted on the upper side of the support plate; the gear frame 102 is mounted on the upper side of the support plate near the driving rotary motor 103; the transmission assembly 105 is located in the gear frame 102, and is used to transmit the kinetic energy of the driving rotary motor 103 to the auger 205, so that the auger 205 can rotate relative to the auger outer cylinder 204.

[0082] It is understandable that the driving rotary motor 103 is mounted on the upper side of the support plate to provide rotary power so that the auger 205 can rotate. The gear rack 102 is mounted on the upper side of the support plate near the driving rotary motor 103, and is used to support and fix the transmission elements in the transmission assembly 105. The transmission assembly 105 is located in the gear rack 102, and it transmits the rotary power of the driving rotary motor 103 to the auger 205, so that the auger 205 can rotate relative to the auger outer cylinder 204, thereby achieving the lifting and transportation of grain. The transmission assembly 105 can adopt a series of gears, belts, chains or other transmission elements, which work together to achieve the transmission of rotary power and the amplification or reduction of torque. The design of the transmission assembly 105 needs to ensure the efficiency and stability of power transmission.

[0083] like Figure 3 As shown, in one embodiment, the transmission assembly 105 includes a driving motor gear 1051, a transmission gear 1052, and a rotating central shaft 1053. The driving motor gear 1051 is located at the gear frame 102 and is in transmission connection with the output end of the driving rotating motor 103; the transmission gear 1052 is located at the gear frame 102 and meshes with the driving motor gear 1051; the upper end of the rotating central shaft 1053 is connected to the transmission gear 1052, and the lower end thereof is connected to the auger 205.

[0084] It can be understood that the drive motor gear 1051 is located in the gear frame 102 and is directly connected to the output end of the drive rotary motor 103. The direct power output of the drive rotary motor 103 is received, and the high-speed rotation of the motor is converted into gear rotation, and the power is prepared to be transmitted to the subsequent transmission gear 1052. The transmission gear 1052 receives and transmits power by meshing with the drive motor gear 1051. The number of teeth and size of the transmission gear 1052 determine the efficiency of power transmission and the conversion ratio of torque. The upper end of the rotating middle shaft 1053 is connected to the transmission gear 1052, and the lower end is connected to the auger 205. It can serve as a bridge for power transmission. The rotating middle shaft 1053 directly transmits the power received from the transmission gear 1052 to the auger 205, so that the auger 205 can rotate relative to the auger outer cylinder 204, thereby achieving the lifting of grain. Through the transmission assembly 105 , the auger 205 blade 202 mechanism 2 can ensure that the kinetic energy of the driving rotary motor 103 is efficiently and accurately transmitted to the auger 205 , thereby achieving stable rotation of the auger 205 .

[0085] In one embodiment, the transmission assembly 105 also includes a rotating outer cylinder 104, a single-row tapered roller bearing 1054, and a thrust ball bearing 1055: the rotating outer cylinder 104 is sleeved on the outer side of the rotating central axis 1053, and its upper end is connected to the slide rail frame 101; the inner edge of the single-row tapered roller bearing 1054 is sleeved on the outer side wall of the rotating central axis 1053, and its outer edge is connected to the inner side wall of the rotating outer cylinder 104; the inner edge of the thrust ball bearing 1055 is sleeved on the outer side wall of the rotating central axis 1053, and its outer edge is connected to the inner side wall of the rotating outer cylinder 104.

[0086] It can be understood that by rotating the outer cylinder 104, the rotating central axis 1053 can be protected from external erosion, and a mounting gap for placing the bearing is formed between the rotating outer cylinder 104 and the rotating central axis 1053, thereby improving the stability of the rotating central axis 1053 during rotation. The single-row tapered roller bearing 1054 is used to bear the combined radial and axial loads, and the smooth rotation between the rotating central axis 1053 and the rotating outer cylinder 104 reduces friction and wear, and improves the life of the transmission assembly 105. The inner edge of the thrust ball bearing 1055 is also sleeved on the outer arm of the rotating central axis 1053, and the outer edge is connected to the inner wall of the rotating outer cylinder 104. The thrust ball bearing 1055 bears the axial load and can withstand a large axial force, ensuring that the auger 205 can still rotate smoothly when subjected to longitudinal pressure. Together with the single-row tapered roller bearing 1054, it provides all-round support and protection for the rotating central axis 1053.

[0087] like Figure 6As shown, in one embodiment, the auger 205 rotor blade 202 mechanism 2 also includes an internal meshing gearwheel 2062, a plurality of pinion gears 2063, and a driving gear 2061: the internal meshing gearwheel 2062 is arranged at the upper end of the auger 205; the plurality of pinion gears 2063 are distributed at intervals along the radial direction of the internal meshing gearwheel 2062, and are all meshed with the internal meshing gearwheel 2062; the driving gear 2061 is located on the central axis of the internal meshing gearwheel 2062, and its outer side is meshed with the plurality of pinion gears 2063, and is transmission-connected to the rotating central axis 1053.

[0088] It is understandable that the internal meshing gear 2062 is arranged at the upper end of the auger 205 and meshes with a plurality of pinions 2063 to distribute power and coordinate the synchronous rotation of the pinions 2063. The plurality of pinions 2063 are distributed at intervals along the radial direction of the internal meshing gear 2062. These pinions 2063 mesh with the internal meshing gear 2062 and drive their own rotation through the rotation of the internal meshing gear 2062. Each pinion 2063 can be independent of other pinions 2063, which can improve the balance and stability of the auger 205 during rotation. The driving gear 2061 meshes with a plurality of pinions 2063 and is in transmission connection with the rotating middle shaft 1053. It converts the rotational force from the rotating middle shaft 1053 into the rotational motion of the internal meshing gear 2062.

[0089] In this way, through the combination of the internal meshing large gear 2062 and the plurality of small gears 2063, a more uniform force distribution can be achieved, the wear of a single gear can be reduced, and the rotation efficiency of the auger 205 can be improved. In addition, this gear system can also provide greater torque, which helps the auger 205 to handle heavier grains more easily. Overall, this transmission mechanism enhances the performance and reliability of the auger 205 rotor 202 mechanism 2.

[0090] like Figure 5 As shown, in one embodiment, the auger 205 rotary blade 202 mechanism 2 further includes a grain distribution cover 203 and a connecting key 2064. The grain distribution cover 203 is located above the rotary blade 202 and is transmission-connected to the rotating central shaft 1053; the connecting key 2064 is installed between the grain distribution cover 203 and the driving gear 2061, so that the grain distribution cover 203 drives the driving gear 2061 to rotate through the connecting rod.

[0091] It is understandable that the grain cover 203 is located above the rotary blade 202, which can effectively prevent the grain lifted from the auger 205 from being overflowed, and at the same time, the grain can be limited to fly out from the maximum radius of the rotary blade 202, so that it can be dispersed more evenly. The grain cover 203 is connected to the rotating middle shaft 1053 in a transmission manner. When the rotating middle shaft 1053 rotates, the grain cover 203 will also rotate accordingly. The grain cover 203 can control and guide the distribution of grain, ensuring that the grain can be evenly distributed on the grain surface, rather than concentrated in one point or area, so as to achieve a more uniform distribution of grain. The connecting key 2064 transmits the rotational power of the grain cover 203 to the driving gear 2061. When the grain cover 203 rotates driven by the rotating middle shaft 1053, the connecting key 2064 ensures that this rotational motion can be effectively transmitted to the driving gear 2061, thereby driving the rotation of the entire gear system and the auger 205. In this way, the grain cover 203 not only participates in the uniform distribution of grain, but also becomes a link in the entire transmission chain, ensuring the efficient transmission of power from the rotating central axis 1053 to the auger 205.

[0092] like Figure 5 As shown, in one embodiment, the auger 205 and the vane 202 mechanism 2 further includes a positioning frame 207 and a pinion 2063 axle.

[0093] The positioning frame 207 is located between the grain cover 203 and the driving gear 2061, and has a makeshift hole in the middle for the rotation trajectory of the connecting key 2064. Its peripheral side is fixedly connected to the auger outer cylinder 204, and has a through hole corresponding to the pinion 2063; the pinion 2063 axle is coaxially arranged on the side of the multiple pinions 2063 facing the positioning frame 207, and the pinion 2063 axle is inserted into the through hole and is rotatably connected to the positioning frame 207.

[0094] It can be understood that the positioning frame 207 is located between the grain cover 203 and the driving gear 2061, and has a clearance hole in the middle to allow the rotation track of the connecting key 2064 to be unobstructed; the peripheral side is fixedly connected to the auger outer cylinder 204 to ensure the stability of the positioning frame 207; and there is a through hole corresponding to the pinion 2063 for inserting and fixing the pinion 2063 axle. The positioning frame 207 plays a role of connection and support. It ensures the correct position and stable rotation of the pinion 2063 axle. At the same time, through its fixed connection with the auger outer cylinder 204, the auger outer cylinder 204 is rotated. When the auger outer cylinder 204 rotates, it drives the rotary blade 202 to rotate, so that the grain lifted by the auger 205 is dispersed by the rotary blade 202. The pinion 2063 axle is inserted into the through hole on the positioning frame 207 to form a rotation connection with the positioning frame 207. The pinion 2063 axle is the central axis of the pinion 2063 rotation, and it is connected to the locating frame 207 through rotation, ensuring the stability and accuracy of the pinion 2063 during the rotation process. The pinion 2063 axle can drive the locating frame 207 to rotate. In this way, the auger 205 and the rotary blade 202 can be driven to rotate at the same time by a driving rotating motor 103, which reduces the setting of the driving source, makes the device more portable, and reduces the manufacturing cost.
