Technical Field
[0001] This invention relates to the field of rice processing equipment technology, specifically a low-breakage bucket elevator for rice processing with a buffer deceleration device. Background Technology
[0002] Bucket elevators are the core vertical conveying equipment in rice processing production lines. They mainly rely on traction components to drive the buckets to circulate. Through a continuous operation of bottom scooping and top tipping unloading, they achieve vertical lifting and conveying of rice materials. They are characterized by high conveying efficiency, small footprint, and strong continuity. They are widely used in various processing steps such as rice cleaning, milling, and grading. The operational stability and material conveying integrity of this equipment directly affect the whole rice yield and processing quality of the finished rice product. It is a key auxiliary equipment to ensure large-scale and automated rice processing.
[0003] In actual use, existing rice processing bucket elevators generally suffer from problems such as high material speed and concentrated impact force during the unloading stage. Most of the equipment lacks a sound buffer and material stabilization structure, making it difficult to effectively decelerate and guide the high-speed falling rice grains. During the unloading process, rice grains are prone to high-speed impact, splashing back and local accumulation and jamming, which easily produces a certain amount of broken rice grains. This cannot fully meet the requirements of fine and low-damage rice processing, and to a certain extent affects the overall quality of the finished rice. There is still room for improvement in the operational effect of adapting to high-quality rice processing. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.
[0018] Reference Figure 1 In this embodiment of the invention, a low-breakage bucket elevator for rice processing with a buffer deceleration device includes: an elevator body 1, which mainly consists of a head, a barrel, a base, a bucket, a traction component, and a drive device. During operation, the drive device drives the traction component to rotate, and the bucket at the base scoops up material and conveys it upward. When it reaches the head, the bucket flips to unload the material, which is discharged from the outlet. The empty bucket returns to the base with the traction component. A discharge box 2 is fixedly connected to the outlet of the head in the elevator body 1. The outlet of the discharge box 2 opens downward, and a discharge pipe 3 is fixedly connected to the bottom of the outlet of the discharge box 2. The discharge pipe 3 communicates with the inside of the discharge box 2. A buffer component 4 is provided on the discharge box 2 and the discharge pipe 3, and a residue removal component 5 is provided on the buffer component 4.
[0019] Reference Figures 2 to 5The buffer component 4 is integrally assembled in the discharge port of the elevator body 1 and the internal area of the discharge box 2. It is the core buffer and speed reduction structure of the whole machine. It is mainly composed of limiting plate 41, guide plate 1 42, mounting block 43, spring 44, guide plate 2 45, rotating rod 46, receiving plate 47, mounting frame 1 48, discharge bag 49, mounting frame 2 410, separator 411, and mounting rod 412. Among them, there are four sets of limiting plates 41, which are symmetrically installed on the left and right sides inside the discharge port of the elevator head. The two sets of limiting plates 41 on each side are arranged in a staggered and inclined manner. The end face of the limiting plate 41 facing the inside of the elevator head is set as a sloping structure, which can effectively avoid the problem of rice material accumulation and jamming. An L-shaped guide plate 42 is slidably inserted between the side limiting plates 41, allowing the guide plate 42 to slide stably along the inclined trajectory of the limiting plates 41. A right-angled triangular mounting block 43 is fixedly mounted on the outer side of the machine head and below the discharge port. The inclined surface of the mounting block 43 is directly opposite to the short side end face of the guide plate 42 and they are parallel to each other. A spring 44 is fixedly connected to the inner side of the short side of the guide plate 42, and the other end of the spring 44 is fixedly connected to the inclined surface of the mounting block 43. In the initial assembly state, the top of the guide plate 42 extends above the traction component and is tangential to the arc surface of the top of the traction component, which can accurately receive the rice material unloaded by the hopper. The discharge box 2 and the guide plate are located inside the discharge box 2. A second guide plate 45 is fixedly installed below the first guide plate 42. The second guide plate 45 is arranged parallel to the long side end face of the first guide plate 42, forming a partial obstruction of the bottom opening of the discharge box 2. Its outer end has a fixed discharge gap with the inner wall of the discharge box 2 as a material flow channel. A longer rotating rod 46 is installed horizontally through the discharge box 2. Four sets of receiving plates 47 are symmetrically fixed to the outer circle of the rotating rod 46. The length of the receiving plate 47 matches the length of the internal cavity of the discharge box 2. Magnetic blocks with opposite poles are embedded on the outer side of the receiving plate 47 at corresponding positions with the inner wall of the discharge box 2. In the initial state, the horizontal receiving state is maintained by magnetic attraction. An installation frame 48 is sleeved on the outside of the discharge box 2, and its bottom end is connected to the fabric material. The discharge bag 49 has a smaller mounting frame 410 at its bottom, forming a flow guide structure that is wider at the top and narrower at the bottom. Multiple sets of partition plates 411 of the same material are evenly distributed inside the discharge bag 49. Two sets of mounting rods 412 parallel to the rotating rod 46 are symmetrically mounted on both sides of the mounting frame 410. When the equipment is running and unloading, the high-speed rice material carried out by the hopper first falls onto the surface of the guide plate 42. After being guided by the tilt, it falls smoothly. During the movement of the hopper, the guide plate 42 can be pushed to slide and squeeze the spring 44. After the hopper is separated, the spring 44 rebounds and drives the guide plate 42 to reset. After the material is limited and guided by the guide plate 45, it falls onto the horizontal receiving plate 47 for temporary storage.
[0020] The above solution, by adding a multi-stage flow guiding structure and an elastic reset structure to the buffer component 4, can gradually decelerate and buffer the rice material discharged at high speed from the elevator head, completely changing the high-speed direct discharge state of the material. At the same time, by using the inclined limiting structure and the magnetic material receiving structure, material accumulation, splashing and secondary impact are avoided, effectively reducing the rice breakage rate and improving the uniformity and stability of material discharge.
[0021] Reference Figures 6 to 8 Two sets of discharge components 5 are symmetrically assembled on the left and right sides of the discharge bag 49, corresponding to the discharge structure of the buffer component 4. They mainly consist of a connecting ear 51, a rack 52, a gear 53, a separating block 54, a stop block 55, a connecting rod 56, and a straightening plate 57. The connecting ear 51 is rotatably sleeved on the outer circle of the mounting rod 412, allowing free rotation around it. A vertically arranged rack 52 with a vertical tooth structure is fixed to the outside of the connecting ear 51. A gear 53 is fixedly assembled on the outer circle of the rotating rod 46 corresponding to the position of the rack 52. The gear 53 and rack 52 mesh precisely in the initial state. An L-shaped connecting rod 56 is fixedly assembled on the side of the discharge box 2, with its long side extending to the outside of the rack 52. A horizontally arranged straightening plate 57 is fixed at its bottom end. The lower straightening plate 57 is in close contact with the outer straight surface of the rack 52, restricting the deflection of the rack 52 and ensuring that it always maintains a vertical meshing state. The side wall of the discharge box 2 above the rack 52 is fixedly equipped with a right-angled triangular separation block 54. The inclined surface of the separation block 54 is arranged downwards, which can limit and guide the rising rack 52. The inner straight surface of the rack 52 is correspondingly equipped with a fixed stop block 55, which is used for limiting and positioning when the rack 52 deflects and resets. During the operation of the equipment, when enough rice material accumulates on the surface of the receiving plate 47, the gravity of the material overcomes the magnetic attraction constraint force of the magnetic block, causing the receiving plate 47 and the rotating rod 46 to rotate clockwise synchronously, realizing automatic material unloading. During the rotation of the rotating rod 46, the gear 53 is rotated synchronously, driving the meshing rack 52 to move upwards, completing the pre-transmission action of residual material cleaning.
[0022] The above solution involves setting up two sets of symmetrically arranged discharge components 5. Relying on the gear and rack meshing transmission, the straightening limit and inclined plane separation cooperation structure, the automatic vibration of the discharge bag 49 can be achieved by the autonomous power of the equipment unloading. No additional drive equipment is required. This can efficiently clean the residual rice grains adhering and accumulating inside the discharge bag 49, prevent the residual material from becoming moldy and clogging, thus affecting subsequent processing and ensuring the continuous and stable operation of the equipment.
[0023] The working principle of this invention is as follows: After the equipment is started, the drive device continuously drives the traction component to rotate in a cycle. The hopper fixed on the traction component moves down with the component to the feeding area of the machine base, automatically scooping up the rice material to be lifted. Then, it moves vertically upward at a uniform speed with the traction component, continuously conveying the bottom material to the unloading area of the machine head. When the hopper loaded with material reaches the top position of the machine head, it is tilted due to the limiting structure of the machine head, and the rice material inside the hopper begins to be unloaded outward. The high-speed ejected material first accurately falls onto the long side surface of the L-shaped guide plate 42 of the buffer component 4. Since the limiting plate 41 is an inclined and symmetrically arranged structure, the guide plate 42 maintains an inclined state as a whole, which can buffer and decelerate the high-speed falling rice grains, disperse the concentrated impact force of the material, and avoid the rice grains directly hitting the machine head. The equipment casing breaks. As the hopper continues to descend, its sidewall adheres to the surface of guide plate 42 and pushes it towards the discharge box 2. During the sliding of guide plate 42, spring 44 is stretched, causing it to elastically deform and store rebound potential energy. This effectively buffers the hard impact between the hopper and the guide structure, while also adapting to the hopper's trajectory to avoid structural interference and jamming. When the hopper is completely removed from the coverage area of guide plate 42, spring 44 instantly releases its elastic potential energy, quickly pulling guide plate 42 back to its initial working position, ready for the next material receiving and buffering operation. The rice material, buffered and guided by guide plate 42, continues to fall downwards onto the surface of guide plate 45 inside the discharge box 2. Guide plate 45 is flush with guide plate 42. The material is arranged in a horizontal layout, which can guide and stabilize the flow of materials in two stages. At the same time, it blocks most of the opening of the discharge box 2, leaving only a narrow slit on one side as the discharge channel, further reducing the falling speed of the material and achieving uniform material discharge. This prevents material splashing and deviation. The material flows out smoothly and falls onto the horizontally placed receiving plate 47 inside the discharge box 2. In the initial state, the receiving plate 47 is kept horizontal and stationary by the magnetic attraction of the opposite pole magnetic blocks on the inner wall of the discharge box 2, which temporarily stores and stabilizes the material, making the material accumulate evenly and avoiding impact and breakage caused by a large amount of material discharge at any time. As the weight of the rice material accumulated on the surface of the receiving plate 47 increases, the gravity of the material gradually overcomes the magnetic attraction of the magnetic blocks, causing the cross-shaped receiving plate 47 and the rotating rod 46 to rotate clockwise synchronously. The horizontal receiving plate 47 7. The material is flipped and moved downwards, and the temporarily stored rice material is smoothly discharged from the gap of the discharge box 2 and the discharge pipe 3, finally falling into the discharge bag 49 below, completing the material lifting and discharge operation. During the synchronous process of the rotating rod 46 rotating and unloading, the gear 53 fixed on its outer circle rotates synchronously. Through the meshing transmission of the gear and rack, the racks 52 on both sides in a vertical state are driven to move upwards smoothly. During the upward movement, the racks 52 gradually leave the contact limit range of the straightening plate 57. The top of the rack 52 gradually comes into contact with the lower inclined surface of the separating block 54. Under the guidance of the inclined surface, the rack 52 drives the connecting ear 51 to deflect slightly around the mounting rod 412 until the rack 52 and the gear 53 are completely disengaged. At this time, the straight surface of the rack 52 comes into contact with the stop block 55 to complete the limit positioning.After the engagement is released, the rack 52, no longer constrained by the transmission, quickly moves downwards to reset under its own weight. During the downward movement, it re-enters the limiting range of the straightening plate 57. The straightening plate 57 then abuts against the rack 52 again, causing it to deflect in the opposite direction and return to a vertical state, re-engaging with the gear 53. Throughout the reciprocating movement of the rack 52, it simultaneously pulls the discharge bag 49 to complete alternating winding and stretching actions, causing the fabric discharge bag 49 to vibrate regularly. The multiple sets of separators 411 on the inner wall of the bag can further disturb the material. The residual rice grains adhering to the inner wall of the bag and accumulated in the corners are completely shaken off and discharged, completing the automatic residue removal operation. After each unloading and residue removal process, all structures automatically reset to their initial assembly state and enter the next work cycle with the continuous operation of the traction components. The entire process requires no manual intervention, continuously achieving integrated processing of low-damage rice material lifting, smooth unloading, and automatic residue removal. This effectively solves the problems of high unloading impact, high rice breakage rate, and residue accumulation and blockage in traditional bucket elevators, making it suitable for the needs of large-scale and refined rice processing production. The elastic buffer, multi-stage flow guidance and magnetic material stabilization composite structure of the buffer component 4 can decelerate, guide and buffer the high-speed rice grains unloading from the machine head in stages, effectively dissipate the impact force of material unloading, greatly reduce the probability of rice grains being broken by impact, and at the same time avoid material splashing, backflow and accumulation jamming, significantly improve the integrity of rice conveying, ensure the quality of finished rice, and meet the core requirements of low-damage rice processing. The residual removal component 5 achieves automated vibration residual removal by relying on the equipment's own unloading power. It does not require additional power drive components, has strong structural linkage, low energy consumption, and can continuously clean the residual materials adhering to the inside of the discharge bag, preventing residual materials from accumulating and becoming moldy and blocking the discharge channel. This ensures long-term stable and continuous operation of the equipment and effectively reduces the frequency of equipment maintenance and processing losses.
