Grain ration conveying and automatic sorting complete equipment

Abstract

This invention discloses a complete set of automatic sorting and conveying equipment for quantitative grain transport, including a shell assembly comprising a barrel, a feed hopper, a head shell, a discharge hopper, a guide groove, and rotating teeth; a lifting mechanism comprising a conveyor wheel, a bucket belt, fixing nails, a mounting frame, and a bucket; and a pushing mechanism comprising a pushing plate, a rotating shaft, and gears. The gears are slidably connected inside the corresponding guide grooves, and the gears mesh with the corresponding rotating teeth. This invention adds a pushing plate inside the bucket, with the rotating shaft and gears fixed on both sides. The head shell is provided with a guide groove and high / low plates, with two sets of rotating teeth arranged on different sides inside the grooves. When the assembly enters the discharge position, the high / low plates cause the shaft to slide, retracting the locking head and releasing the pushing plate from locking. Subsequently, the rotating teeth on one side drive the gears, driving the pushing plate to deflect, and with the help of centrifugal force, push out all the grain, effectively reducing residue and avoiding a decrease in conveying efficiency and yield.

Description

Technical Field

[0001] This invention relates to the field of grain conveying technology, specifically to a complete set of automatic sorting and operation equipment for quantitative grain conveying. Background Technology

[0002] From harvest to storage, grain undergoes a series of processing steps, including conveying, sorting, and impurity removal. In this process, the raw grain is first precisely and quantitatively fed through a closed-loop control system, forming a continuous and uniform stable flow. Subsequently, the flow enters a multi-stage automatic sorting system, which utilizes differences in particle size, specific gravity, and magnetic properties to automatically separate plump grains from shriveled grains, sand, gravel, metallic foreign objects, and other impurities. This complete set of equipment, integrating quantitative conveying, automatic sorting, and precise impurity removal, is the core equipment for ensuring grain quality and improving storage efficiency.

[0003] Bucket elevators are key equipment in this process, responsible for vertical conveying. Their bucket belts, operating at a constant linear speed, uniformly lift the grain supplied quantitatively from downstream equipment from a lower to a higher position. The centrifugal force generated by the rotation of the head wheel throws the material into the discharge port, achieving continuous and directional transfer of material within a closed channel. It serves as a crucial link connecting various sorting processes.

[0004] However, in actual operation, this centrifugal unloading method has the problem of material residue. When the grain slides out of the hopper under centrifugal force, some particles cannot detach from the hopper due to surface friction and electrostatic adsorption, resulting in incomplete unloading. This is especially true when conveying grain with a certain moisture content, as the material adhesion is significantly enhanced, forming an adhesive layer on the inner wall of the hopper, further increasing the residue. This residual grain returns to the machine base with the hopper, not only reducing the effective conveying efficiency, but also causing secondary crushing of the repeatedly circulated material, increasing the subsequent cleaning burden. Long-term accumulation may also lead to material mold and cross-contamination, posing a direct threat to the "quantitative" accuracy and "sorting" quality of the entire production line. Summary of the Invention

[0005] The purpose of this invention is to provide a complete set of automatic sorting and operation equipment for quantitative grain conveying, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a complete set of automatic sorting and conveying equipment for quantitative grain transport, comprising a shell assembly, the shell assembly comprising a barrel, a feed hopper fixedly disposed on the bottom side of the barrel, a head shell fixedly disposed on the top of the barrel, a discharge hopper fixedly disposed at the end of the head shell, a motor fixedly disposed on the top of the barrel, a transmission component disposed on the output end of the motor, and a pair of guide grooves symmetrically fixed on both sides inside the head shell, with rotating teeth disposed on the inner side of the guide grooves;

[0007] The machine barrel and the machine head housing are equipped with a lifting mechanism for conveying grain. The lifting mechanism includes two conveying wheels that are rotatably installed at the bottom of the machine barrel and inside the machine head housing, respectively. The conveying wheel inside the machine head housing is fixedly installed at the other end of the transmission component. A bucket belt is sleeved between the two conveying wheels. Several pairs of fixing nails are fixed at equal intervals on the outer side of the bucket belt. A mounting frame is fixed on each pair of fixing nails, and a bucket is fixed on the mounting frame.

[0008] The hopper is equipped with a feeding mechanism for pushing grain. The feeding mechanism includes a feeding plate rotatably connected to the inside of the hopper. The feeding plate is symmetrically fixed with rotating shafts that pass through the side of the hopper and both ends of the mounting frame. Gears are fixed at the ends of the rotating shafts.

[0009] The gear is slidably connected inside the corresponding guide groove, and the gear meshes with the corresponding rotating tooth.

[0010] Preferably, a high and low plate is fixed inside the guide groove, and both ends of the high and low plate are inclined surfaces.

[0011] Preferably, a pair of locking grooves are symmetrically opened on the inner side of the mounting frame, and several protruding teeth are fixed at equal intervals on the edge of the bucket.

[0012] Preferably, the rotating shaft is a hollow structure, and the pusher plate, which is coaxial with the rotating shaft, has a sliding groove inside. A pair of bases are symmetrically fixed on the end surface of the pusher plate away from its own rotation side.

[0013] Preferably, the rotating shaft is provided with a locking component for controlling when the pusher plate rotates. The locking component includes a shaft that is slidably installed inside the rotating shaft, a roller that is fixedly installed at the outer end of the shaft and the roller abuts against the corresponding high and low plates, the inner end of the shaft that is slidably connected to the corresponding slide groove, and an adjustment groove that is opened in the inner end of the shaft. A second spring and a lock head are installed inside the adjustment groove. The lock head is elastically connected to the shaft through the second spring and is engaged with the corresponding lock groove.

[0014] Preferably, the pusher plate is provided with a feeding assembly for preventing grain from returning to the bottom of the barrel. The feeding assembly includes a feeding plate rotatably mounted on the side of the pusher plate. Rotating rods are symmetrically fixed at both ends of the rotating side of the feeding plate. The rotating rods are rotatably connected to the corresponding base. A torsion spring is sleeved on the rotating rod and installed inside the corresponding base. Three inclined plates are equidistantly fixed on the rotating side of the feeding plate, and the inclined plates abut against the corresponding protruding teeth.

[0015] Preferably, the side of the pusher plate away from the feed plate is provided with a blowing mechanism for blowing off the material adhering to the contact area between the pusher plate and the bucket. The blowing mechanism includes an air receiving box fixedly disposed on the side of the pusher plate. An air chamber is formed inside the air receiving box and the pusher plate. A piston plate is slidably disposed inside the air chamber. A slide rod is fixed on the piston plate. The slide rod passes through the pusher plate. A connector is rotatably connected to the end of the slide rod. The connector is movably mounted on the corresponding inclined plate. A pair of limiting grooves are symmetrically formed at the end of the slide rod. A pair of air inlets communicating with the air chamber are symmetrically formed on the air receiving box. A first one-way valve is installed inside the air inlet. Exhaust pipes are symmetrically connected to both sides of the air receiving box. The two ends of the exhaust pipes are respectively connected to the air chamber and the inside of the pusher plate. A second one-way valve is installed inside the exhaust pipe.

[0016] Preferably, the pusher plate is provided with a venting mechanism on the side near the deflector plate to control when the blowing mechanism blows and draws air. The venting mechanism includes a single-channel block and a double-channel block fixed to the side of the pusher plate near the deflector plate. A pair of communicating cavities are symmetrically opened in the pusher plate on both sides of the air receiving box. The two ends of the communicating cavities are respectively connected to the exhaust pipe and the single-channel block and the double-channel block. A pair of receiving slots are also symmetrically opened in the pusher plate on both sides of the air receiving box. A single sealing plate and a double sealing plate and a third spring are slidably connected in the receiving slots. The single sealing plate and the double sealing plate are elastically connected to the corresponding receiving slots through the third spring. The single sealing plate and the double sealing plate abut against the single-channel block and the double-channel block respectively. The sides of the single sealing plate and the double sealing plate are fixed to one end of a connecting rod. The other end of the connecting rod is inserted into the corresponding limiting slot.

[0017] Preferably, a pair of single-channel blocks are fixed on both sides of the pusher plate near the deflector plate, and a pair of double-channel blocks are symmetrically fixed in the middle of the pusher plate near the deflector plate. The single-channel blocks have air ducts facing one side inside, and the double-channel blocks have air ducts facing both sides inside. The single sealing plate closes the air ducts of the single-channel blocks, and the double sealing plate closes the air ducts of the double-channel blocks.

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

[0019] 1. The bucket has been improved by installing a rotatable pusher plate inside. A rotating shaft and gears are fixed on both sides of the pusher plate. Guide grooves and high / low plates are installed on the inner walls of both sides of the machine head housing. Two sets of rotating teeth on different sides are installed inside the guide grooves. When the locking groove enters the unloading position, the high / low plates shorten the distance, allowing the shaft to slide inwards onto the pusher plate, thus retracting the locking head and releasing the mounting frame from the pusher plate. Then, the rotating teeth on one side drive the gear to rotate, causing the pusher plate to deflect inside the bucket. Combined with centrifugal force, this reliably and stably pushes all the grain out of the bucket, effectively preventing some grain from remaining in the bucket and reducing the efficiency and yield of the bucket elevator. After unloading, when the gear slides out of the guide groove, the pusher plate inside the bucket returns to its initial position, preparing for the next grain transport.

[0020] 2. Protruding teeth are installed at the edge of the bucket opening. When the pusher plate rotates to the bucket opening, the protruding teeth just abut against the inclined plate on the feed plate, squeezing the inclined plate, thereby driving the feed plate to rotate quickly, patting the remaining grain that finally falls down, and patting the grain into the discharge hopper to enter the next stage, avoiding the problem of the remaining grain falling back into the machine barrel.

[0021] 3. An air receiving box is installed on the side of the pusher plate away from the feed plate. The air receiving box is filled with gas. When the protruding teeth squeeze the inclined plate and drive the feed plate to rotate, the inclined plate drives the piston plate to slide in the air chamber through the connector and slide rod, thereby compressing the gas. The gas in the air chamber is then sprayed from the single-channel block and the double-channel block towards the front surface of the pusher plate that contacts the bucket, thus blowing off any impurities that may adhere to the front surface and ensuring that the inside of the bucket and the surface of the pusher plate are clean. The single-channel block and the double-channel block are equipped with single-sealing plates and double-sealing plates to close the air passages. During the grain transport stage, the single-sealing plates and double-sealing plates can prevent impurities from entering the single-channel block and the double-channel block and causing channel blockage. While the inclined plate pushes the slide rod to slide, the slide rod can also drive the single-sealing plates and double-sealing plates to slide through the connecting rod, so that the single-sealing plates and double-sealing plates are put into the receiving slot, exposing the air passages of the single-channel block and the double-channel block, allowing the airflow to be sprayed out smoothly.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-14 The present invention provides a technical solution: a complete set of automatic sorting and operation equipment for quantitative grain conveying;

[0039] Example 1: Please refer to Figure 1 , Figure 9 This embodiment describes one of the implementable structures of a complete set of automatic sorting and operation equipment for quantitative grain conveying;

[0040] The housing assembly 1 includes a barrel 10, a feed hopper 11 fixedly disposed on the bottom side of the barrel 10, a head housing 12 fixedly disposed on the top of the barrel 10, a discharge hopper 13 fixedly disposed at the end of the head housing 12, a motor 14 fixedly disposed on the top of the barrel 10, and a transmission component 15 disposed on the output end of the motor 14.

[0041] In this embodiment, the grain is evenly pushed into the feed hopper 11 in the previous step. The motor 14 and the transmission component 15 drive the lifting mechanism 2 to rotate in a cycle, conveying the grain to the discharge hopper 13 at the end of the machine head housing 12 at a uniform speed and in a quantitative manner. The transmission component 15 consists of two pulleys of different sizes and a belt. The small pulley is fixedly installed at the output end of the motor 14, and the large pulley is fixedly installed at one end of the shaft of the conveyor wheel 20. The large and small pulleys are connected by a belt to transmit the kinetic energy of the motor 14 to the lifting mechanism 2.

[0042] The machine barrel 10 and the machine head housing 12 are equipped with a lifting mechanism 2 for conveying grain. The lifting mechanism 2 includes two conveying wheels 20 that are rotatably installed at the bottom of the machine barrel 10 and inside the machine head housing 12, respectively. The conveying wheel 20 inside the machine head housing 12 is fixedly installed at the other end of the transmission component 15. A bucket belt 21 is sleeved between the two conveying wheels 20. Several pairs of fixing nails 23 are fixed at equal intervals on the outer side of the bucket belt 21. A mounting frame 22 is fixed on each pair of fixing nails 23. A bucket 25 is fixed on the mounting frame 22. A pair of locking grooves 24 are symmetrically opened on the inner side of the mounting frame 22.

[0043] In this embodiment, the speed of the bucket belt 21 is constant, and the amount of grain loaded into each bucket 25 is fixed. After the bucket 25 rotates with the bucket belt 21 into the machine head housing 12, it moves around the conveyor wheel 20 in a circle. The grain in the bucket 25 is thrown out by centrifugal force and flows into the next stage from the discharge hopper 13. The locking groove 24 can be engaged with the locking head 45 to connect the mounting frame 22 and the pusher plate 30 into a whole, preventing the pusher plate 30 from rotating.

[0044] The bucket 25 is equipped with a pushing mechanism 3 for pushing grain. The pushing mechanism 3 includes a pushing plate 30 rotatably connected inside the bucket 25. The pushing plate 30 is symmetrically fixed on both sides with rotating shafts 31 that pass through the side of the bucket 25 and both ends of the mounting frame 22. The end of the rotating shaft 31 is fixed with a gear 32. The machine head housing 12 is symmetrically fixed on both sides with a pair of guide grooves 16. The guide grooves 16 are provided with rotating teeth 17 inside. The gear 32 is slidably connected inside the corresponding guide groove 16, and the gear 32 is meshed with the corresponding rotating teeth 17.

[0045] In this embodiment, before the gear 32 enters the guide groove 16, the pusher plate 30 inside the bucket 25 is attached to one side of the bucket 25 and used as the side wall of the bucket 25. When each bucket 25 moves to the top of the bucket belt 21, it begins to flip and unload. Under the action of centrifugal force, the grain in the bucket 25 is thrown out and enters the discharge hopper 13. At this time, the gears 32 on both sides of the bucket 25 enter the guide groove 16 and mesh with the rotating teeth 17 on the inner wall of the guide groove 16 during the movement, thus rotating. Finally, the rotating shaft 31 drives the pusher plate 30 to rotate inside the bucket 25. The end of the pusher plate 30 away from the rotating shaft 31 scrapes the arc-shaped inner wall of the bucket 25. With the help of centrifugal force, all the grain in the bucket 25 is pushed out. Especially when the grain is wet, some grain particles, impurities or chaff can also be scraped off by the pusher plate 30. Finally, they are thrown out by centrifugal force near the opening of the bucket 25, reducing the residue of grain and other materials in the bucket 25, ensuring the cleanliness of the bucket 25, transportation efficiency and effectively preventing secondary damage to the grain.

[0046] like Figure 5 As shown, the guide groove 16 consists of an arc-shaped groove and a vertical groove. Inside the arc-shaped groove, the rotating teeth 17 are set on the inner annular wall of the guide groove 16 (with the center of the arc-shaped groove as the reference, the same below). Inside the vertical groove, the rotating teeth 17 are set on the outer annular wall of the guide groove 16. In this way, the gear 32 can rotate forward and reverse sequentially during its movement in the guide groove 16, which corresponds to the two processes of the pusher plate 30 rotating towards the opening of the hopper 25 and rotating back to the initial position from the opening. This realizes the function of the pusher plate 30 to both push material and reset.

[0047] The rotating shaft 31 is equipped with a locking component 4 for controlling when the pusher plate 30 rotates. The locking component 4 includes a shaft 40 that is slidably installed inside the rotating shaft 31. A roller 41 is fixedly installed at the outer end of the shaft 40 and the roller 41 abuts against the corresponding high and low plate 18. The inner end of the shaft 40 is slidably connected to the corresponding slide groove 33. An adjustment groove 43 is opened in the inner end of the shaft 40. A second spring 44 and a lock head 45 are installed inside the adjustment groove 43. The lock head 45 is elastically connected to the shaft 40 through the second spring 44 and is engaged with the corresponding lock groove 24.

[0048] In this embodiment, a shaft 40 is also slidably arranged inside the rotating shaft 31. Before the gear 32 enters the guide groove 16, the outer end of the shaft 40 protrudes from the outer end of the rotating shaft 31, making the roller 41 very close to the inner wall of the barrel 10 and the head housing 12. In this state, the locking head 45 at the inner end of the shaft 40 is inserted into the corresponding locking groove 24, so that the pusher plate 30 is connected to the mounting frame 22. The pusher plate 30 cannot rotate freely, ensuring that the bucket 25 will not leak grain due to the rotation of the pusher plate 30 during grain transportation. A high and low plate 18 is fixed in the guide groove 16, which can shorten the straight distance between the high and low plate 18 and the bucket 25. When the bucket 25 rotates to the top of the bucket belt 21 and the gear 32 enters the guide groove 16, the grain inside the bucket 25 begins to be thrown out. At this time, it is necessary to release the locking of the pusher plate 30 so that the pusher plate 30 can rotate smoothly. Therefore, after gear 32 enters guide groove 16, high and low plates 18 squeeze roller 41, causing shaft 40 to slide into the rotating shaft 31. Shaft 40 compresses first spring 42, and at the same time, the inner end of shaft 40 pushes lock head 45 towards the middle of push plate 30. Since the side of lock groove 24 that contacts the inclined surface of lock head 45 is an inclined surface with the same angle, the pushing force causes lock head 45 to slide into shaft 40 and compress second spring 44, thereby releasing the connection between push plate 30 and mounting bracket 22. The unlocked state is as follows: Figure 8 As shown; subsequently, gear 32 begins to mesh with rotating gear 17, driving rotating shaft 31 and pusher plate 30 to rotate.

[0049] The guide groove 16 is fixed with a high and low plate 18, and both ends of the high and low plate 18 are inclined surfaces.

[0050] In this embodiment, in order to ensure that the roller 41 rolls smoothly when it contacts the high and low plates 18 when the gear 32 enters the guide groove 16 and slides out of the guide groove 16, thereby reducing vibration and ensuring the smooth sliding of the shaft 40.

[0051] The rotating shaft 31 has a hollow structure. The pusher plate 30, which is on the same axis as the rotating shaft 31, has a groove 33 inside. A pair of bases 34 are symmetrically fixed on the end surface of the pusher plate 30 away from its own rotation side.

[0052] In this embodiment, the slide groove 33 is provided so that the inner end of the roller 41 can slide inside the pusher plate 30, thereby realizing the pop-out and retraction of the lock head 45.

[0053] Example 2: Please refer to Figure 8 , Figure 10 - Figure 12 Based on Embodiment 1, this embodiment takes into account that the setting of the pushing mechanism 3 in Embodiment 1 is equivalent to adding a new pushing force under the action of centrifugal force, ensuring that all the grain in the bucket 25 is thrown out. As we all know, the direction of centrifugal force is away from the center of the circle. At the end of the process of throwing out the grain, the opening of the bucket 25 is downward, and its arc surface will block the throwing out of the grain, causing some of it to fall downward into the machine barrel 10 and eventually fall back to the bottom of the machine barrel 10, where it will be scooped up again by other buckets 25. This process is repeated continuously, which will damage the grain particles and is not conducive to the efficiency of grain conveying. Therefore, Embodiment 2 solves the problem that at the end of the process of throwing out the grain, some grain falls vertically back into the machine barrel 10 due to the obstruction of the bucket 25.

[0054] The edge of the dustpan 25 is fixed with several protruding teeth 26 at equal intervals.

[0055] In this embodiment, the protruding tooth 26 is used to abut against the inclined plate 51 on the feeding plate 50 when the pusher plate 30 rotates to the opening of the bucket 25, so that the feeding plate 50 rotates instantaneously.

[0056] The pusher plate 30 is provided with a feeding assembly 5 to prevent grain from returning to the bottom of the barrel 10. The feeding assembly 5 includes a feeding plate 50 rotatably mounted on the side of the pusher plate 30. Rotating rods 53 are symmetrically fixed at both ends of the rotating side of the feeding plate 50. The rotating rods 53 are rotatably connected to the inside of the corresponding base 34. A torsion spring 52 is sleeved on the rotating rod 53. The torsion spring 52 is installed inside the corresponding base 34. Three inclined plates 51 are equidistantly fixed on the rotating side of the feeding plate 50, and the inclined plates 51 abut against the corresponding protrusions 26.

[0057] In this embodiment, the feeding plate 50 is elastically rotatably connected to the base 34 via the rotating rod 53 and the torsion spring 52. When the pushing plate 30 rotates to the opening of the hopper 25, the inclined plate 51 abuts against the corresponding protrusion 26. The protrusion 26 squeezes the inclined plate 51, causing the feeding plate 50 to rotate rapidly. The grain falling from the feeding plate 50 is patted into the discharge hopper 13, effectively preventing the grain from falling directly into the barrel 10. When the feeding plate 50 rotates, the torsion spring 52 stores force. During the rotation phase of the pushing plate 30, the protrusion 26 no longer abuts against the inclined plate 51, and under the elastic force of the torsion spring 52, the feeding plate 50 quickly resets and reattaches to the surface of the pushing plate 30.

[0058] Example 3: Please refer to Figure 11 - Figure 14Based on Embodiment 1, this embodiment takes into account that while the pusher plate 30 pushes the grain in Embodiment 1, it can scrape off the impurities adhering to the arc surface of the bucket 25. However, since the impurities are sticky, they may accumulate on the front surface of the pusher plate 30 and the bucket 25, making them difficult to remove and causing local pollution. This will also affect the next transportation. Therefore, Embodiment 3 solves the problem of impurities easily remaining on the front surface of the pusher plate 30 and the bucket 25 through the following structure.

[0059] A blowing mechanism 6 is provided on the side of the pusher plate 30 away from the pusher plate 50 for blowing off the material adhering to the contact area between the pusher plate 30 and the bucket 25. The blowing mechanism 6 includes an air receiving box 60 fixedly installed on the side of the pusher plate 30. An air chamber 61 is opened inside the air receiving box 60 and the pusher plate 30. A piston plate 62 is slidably installed inside the air chamber 61. A sliding rod 63 is fixed on the piston plate 62. The sliding rod 63 passes through the pusher plate 30. A connector 65 is rotatably connected to the end of the sliding rod 63. The connector 65 is movably installed on the corresponding inclined plate 51. A pair of limiting grooves 64 are symmetrically opened at the end of the sliding rod 63. A pair of air inlets 66 are symmetrically opened on the air receiving box 60 and communicate with the air chamber 61. A first one-way valve 67 is installed inside the air inlet 66. Exhaust pipes 68 are symmetrically connected to both sides of the air receiving box 60. The two ends of the exhaust pipes 68 are respectively connected to the air chamber 61 and the inside of the pusher plate 30. A second one-way valve 69 is installed inside the exhaust pipes 68.

[0060] In this embodiment, the piston plate 62 inside the air chamber 61 is movably connected to the inclined plate 51 via the slide rod 63 and the connector 65. When the protruding tooth 26 presses against the inclined plate 51, causing the feeding plate 50 to rotate, the inclined plate 51 pushes the piston plate 62 to slide within the air chamber 61 via the slide rod 63, compressing the gas inside the air chamber 61. This causes the gas to be ejected from the exhaust pipe 68, the connecting cavity 72, the single-channel block 70, and the double-channel block 71. The gas ejected from the single-channel block 70 and the double-channel block 71 can cover the frontal surface of the pusher plate 30 in contact with the bucket 25, blowing off all the accumulated impurities, which are then quickly... The rotating material-push plate 50 is pushed into the discharge hopper 13; during the reset of the material-push plate 50 under the elastic force of the torsion spring 52, the inclined plate 51 pulls the slide rod 63 outward, causing the piston plate 62 to slide into the push plate 30, forming air intake, and external air fills the air chamber 61 through the air intake duct 66; the air intake duct 66 and the exhaust pipe 68 are respectively provided with a first one-way valve 67 and a second one-way valve 69. When exhausting, the first one-way valve 67 closes the air intake duct 66 and the second one-way valve 69 opens the exhaust pipe 68. When intakeing, the first one-way valve 67 opens the air intake duct 66 and the second one-way valve 69 closes the exhaust pipe 68.

[0061] The pusher plate 30, near the deflector plate 50, is equipped with a venting mechanism 7 that controls when the blowing mechanism 6 blows and draws air. The venting mechanism 7 includes a single-channel block 70 and a double-channel block 71 fixed to the side of the pusher plate 30 near the deflector plate 50. A pair of symmetrically arranged communicating cavities 72 are formed inside the pusher plates 30 on both sides of the air receiving box 60. The two ends of the communicating cavities 72 are respectively connected to the exhaust pipe 68 and the single-channel block 70 and double-channel block 71. The pusher plates 30 on both sides of the air receiving box 60 also have... A pair of symmetrical storage slots 73 are provided. A single sealing plate 74 and a double sealing plate 75 and a third spring 76 are slidably connected in the storage slots 73 respectively. The single sealing plate 74 and the double sealing plate 75 are elastically connected to the corresponding storage slots 73 by the third spring 76. The single sealing plate 74 and the double sealing plate 75 abut against the single channel block 70 and the double channel block 71 respectively. The sides of the single sealing plate 74 and the double sealing plate 75 are fixed to one end of the connecting rod 77, and the other end of the connecting rod 77 is inserted into the corresponding limiting slot 64.

[0062] In this embodiment, during grain transportation, both the single-channel block 70 and the double-channel block 71 will be buried by the grain. Additionally, the grain may be damp. Since the air passages of both the single-channel block 70 and the double-channel block 71 are open, without obstruction, impurities will fill the air passages, and even the connecting cavity 72 and the exhaust pipe 68, causing blockage and poor airflow. Therefore, a single sealing plate 74 and a double sealing plate 75 are respectively placed on the side of the single-channel block 70 with its air passage and on both sides of the double-channel block 71 to block the air passages of the single-channel block 70 and the double-channel block 71, preventing impurities from entering. The double sealing plate 75 is formed by connecting two single sealing plates 74. The single sealing plate 74 and the double sealing plate 75 are fixedly connected to the sliding rod 63 via the connecting rod 77, and the connecting rod 77 is restricted by the limiting groove 64. Even under the heavy pressure of the grain, as long as the feeding plate 50 does not rotate, the sliding rod 63 will not retract, and the connecting rod 77 will naturally be unable to drive the single channel block 70 or the double channel block 71 to slide. The air passages of the single channel block 70 and the double channel block 71 will not open, and impurities will not accidentally enter the air passages. When the feeding plate 50 starts to rotate, the sliding rod 63 slides into the air receiving box 60, and the connecting rod 77 moves accordingly. The connecting rod 77 drives the single sealing plate 74 and the double sealing plate 75 to slide into the corresponding receiving groove 73, compressing the corresponding third spring 76, exposing the air passages of the single channel block 70 and the double channel block 71. At the same time, the gas in the air chamber 61 is ejected from the air passages of the single channel block 70 and the double channel block 71, respectively.

[0063] A pair of single-channel blocks 70 are fixed on both sides of the pusher plate 30 near the deflector plate 50, and a pair of double-channel blocks 71 are symmetrically fixed in the middle of the pusher plate 30 near the deflector plate 50. The single-channel block 70 has an air duct facing one side inside, and the double-channel block 71 has an air duct facing both sides inside. The single sealing plate 74 closes the air duct of the single-channel block 70, and the double sealing plate 75 closes the air duct of the double-channel block 71.

[0064] In this embodiment, according to Figure 11 and Figure 13 As shown, the air passage inside the single-channel block 70 is an arc-shaped structure opening to the side, while the air passage inside the double-channel block 71 is a Y-shaped structure opening to both sides. The single sealing plate 74, which is attached to the side of the single-channel block 70, can just close the air passage opening on the side of the single-channel block 70, and opening the air passage opening when it is moved horizontally. Similarly, the double sealing plate 75 can close the air passage openings on both sides of the double-channel block 71, and opening the air passage opening when it is moved horizontally. This orientation of the air passage opening just covers the frontal surface of the pusher plate 30 and the hopper 25. Each time the hopper 25 unloads material, the airflow ejected from the single-channel block 70 and the double-channel block 71 will blow away the accumulated impurities, ensuring the cleanliness of the pusher plate 30 and the hopper 25.

[0065] Working principle: The motor 14 drives the conveyor wheel 20 inside the machine head housing 12 to rotate through the transmission component 15. The conveyor wheel 20 drives the bucket belt 21 to rotate. Several buckets 25 fixed on the surface of the bucket belt 21 move synchronously. In the previous stage, grain is put into the machine cylinder 10 through the feed hopper 11. Each bucket 25 below the feed hopper 11 receives part of the grain and conveys it upward. When it reaches the top of the bucket belt 21, it rotates in a circle. Using centrifugal force, the grain inside the bucket 25 is thrown out and into the discharge hopper 13, and then enters the next stage from the discharge hopper 13.

[0066] Each bucket 25 that reaches the top of the bucket belt 21 and begins to throw out grain has its gears 32 on both sides enter the corresponding guide groove 16. First, the roller 41 protruding from the outer end of the rotating shaft 31 is squeezed by the high and low plates 18 inside the guide groove 16, slides into the rotating shaft 31, and compresses the first spring 42. At the same time, the locking head 45 at the inner end of the shaft 40 slides out from the locking groove 24 inside the mounting frame 22, and enters the shaft 40 as it slides out, compressing the second spring 44. Finally, the locking head 45 separates from the locking groove 24, releasing the mounting frame 22 from restricting the push plate 30.

[0067] As the bucket belt 21 continues to rotate, the gear 32 continues to slide in the guide groove 16 and meshes with the rotating tooth 17 on the inner ring of the guide groove 16. Driven by the rotating tooth 17, the gear 32 rotates and drives the pusher plate 30 to rotate in the bucket 25 through the rotating shaft 31. The pusher plate 30, in conjunction with the centrifugal force of the rotating bucket 25, pushes out all the grain inside the bucket 25 and scrapes off the impurities adhering to the inner wall of the bucket 25.

[0068] At the end of the engagement between gear 32 and rotating gear 17, the discharge of hopper 25 also enters its final stage, and the remaining grain may fall under the influence of gravity. At this time, pusher plate 30 rotates until inclined plate 51 abuts against the protruding tooth 26 at the opening of hopper 25. The protruding tooth 26 presses against inclined plate 51, causing inclined plate 51 to drive pusher plate 50 to rotate rapidly. Pusher plate 50 rotates around rotating rod 53, and rotating rod 53 causes torsion spring 52 to store force. Pusher plate 50 rotates rapidly, patting the falling grain and patting the remaining grain into discharge hopper 13.

[0069] During the rapid rotation of the feed plate 50 driven by the inclined plate 51, the inclined plate 51 drives the piston plate 62 to slide in the air chamber 61 through the connector 65 and the slide rod 63, thereby compressing the gas inside the air chamber 61. The compressed gas will close the first one-way valve 67 in the air inlet 66 and open the second one-way valve 69 in the exhaust pipe 68. The compressed gas enters the exhaust pipe 68 and is then ejected from the single-channel block 70 and the double-channel block 71 from the connecting cavity 72, blowing off the impurities adhering to the part where the pusher plate 30 contacts the hopper 25. The blown-off impurities are then discharged into the discharge hopper 13 along with the grain under the tapping of the feed plate 50.

[0070] As the inclined plate 51 drives the slide rod 63 to slide, the slide rod 63 drives the single sealing plate 74 and the double sealing plate 75 to slide into the storage groove 73 through the connecting rod 77. The single sealing plate 74 and the double sealing plate 75 compress the third spring 76 in the storage groove 73. The sliding of the single sealing plate 74 and the double sealing plate 75 exposes the air ducts on the sides of the single channel block 70 and the double channel block 71, thereby allowing the gas to be ejected and successfully blow away the impurities.

[0071] Then, as the bucket belt 21 continues to rotate, the bucket 25, after unloading, begins to descend. The gear 32 enters the vertical section at the bottom of the guide groove 16 and meshes with the rotating tooth 17 on the outer ring of the guide groove 16. Driven by the gear 32, the shaft 31 rotates in the opposite direction, causing the pusher plate 30 to rotate. The feeding assembly 5 follows the pusher plate 30 back, loses the protruding tooth 26 that presses against the inclined plate 51, and under the elastic force of the torsion spring 52, the feeding plate 50 reverses and finally re-attaches to the surface of the pusher plate 30.

[0072] During this process, the feed plate 50 drives the inclined plate 51 to reset. The inclined plate 51 pulls back the piston plate 62 through the connector 65 and the slide rod 63. The sliding of the piston plate 62 causes the first one-way valve 67 inside the air intake duct 66 to open, and external air enters the air chamber 61. The entering gas compresses the second one-way valve 69, causing the second one-way valve 69 to close the exhaust pipe 68. Finally, the gas refills the air chamber 61.

[0073] As the slide bar 63 slides outward toward the material feeding plate 50, the slide bar 63 pulls the connecting rod 77 using the limiting groove 64. The connecting rod 77 drives the single sealing plate 74 and the double sealing plate 75 to slide out of the storage groove 73. The third spring 76 extends, and the single sealing plate 74 and the double sealing plate 75 re-close the air duct openings of the single channel block 70 and the double channel block 71.

[0074] When gear 32 separates from the outer ring rotating tooth 17 of guide groove 16, push plate 30 is just reset. Then, roller 41 slides out from the slope of high and low plate 18, loses the contact of high and low plate 18, and under the elastic force of first spring 42, the outer end of shaft 40 slides out from the outer end of rotating shaft 31, and roller 41 is exposed. At the same time, the locking head 45 at the inner end of shaft 40 is aligned with locking groove 24, and second spring 44 pushes locking head 45 into locking groove 24, reconnecting mounting bracket 22 and push plate 30, so that push plate 30 cannot rotate.

[0075] After resetting, the bucket 25 descends as the bucket belt 21 rotates, ready to load new grain.
