Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevators, specifically an elevator for conveying fruit. Background Technology
[0002] In fruit conveying, inclined elevators work by using a mechanical linkage to continuously transport fruit from a low to a high position. Discharge is achieved via a distribution plate at the end. The elevator is typically powered by a motor, with a speed reducer regulating the rotational speed before transmitting power to the drive shaft (or sprockets, rollers, etc.). This ensures the conveying components operate at a stable speed, preventing damage from excessive speed or reduced efficiency. The conveying components carry and transport the fruit. Common conveying components include chain plates, belts, and mesh belts. For fragile materials like fruit, food-grade belts (such as PU belts) or mesh belts are often used. These have smooth surfaces and a certain degree of friction, allowing them to support the fruit while minimizing friction damage during transport. If the lifting angle is large (e.g., exceeding 30°), belts with baffles or hoppers may be used to prevent the fruit from sliding down the inclined section.
[0003] Fruit enters the lower conveyor section of the elevator through the feed inlet. As the conveying components (such as belts) operate continuously, the fruit is carried in an upward tilt. The tilt angle needs to be designed in accordance with the characteristics of the fruit (such as size, weight, and surface smoothness), and is usually between 15° and 45°. Too small an angle will increase the equipment's footprint, while too large an angle will cause the fruit to slip. It is necessary to balance this by adjusting the conveying speed or adding baffles.
[0004] The elevator has a distribution plate at the end. When the fruit reaches the top of the elevator (high end) with the conveyor, the fruit will be separated from the conveyor by gravity or centrifugal force due to the rotation of the conveyor (such as the belt going around the top roller) and crash into the distribution plate. The traditional distribution plate is a rectangular shell welded from 304 stainless steel. The inside of the distribution plate forms a cavity, which will generate a lot of noise when the object falls on the plate. The fruit is easily damaged after it comes into rigid contact with the distribution plate. Utility Model Content
[0005] The purpose of this utility model is to provide a fruit conveying elevator to solve the defects mentioned in the background art.
[0006] To achieve the above objectives, a fruit conveying elevator is provided, comprising an elevator body, a conveyor belt mounted on the elevator body, a material drop frame fixedly provided at the end of the elevator body, a material distribution plate body installed inside the material drop frame, a silicone plate covering the surface of the material distribution plate body, a corrugated fixing structure fixedly connected to the bottom of the silicone plate, and a PVC plate fixedly connected to the bottom of the corrugated fixing structure.
[0007] Furthermore, the material distribution plate body is composed of three parts: a silicone plate, a PVC plate, and a corrugated fixing structure, which are arranged in layers.
[0008] Furthermore, the silicone sheet and the PVC sheet are fixed and supported by a corrugated fixing structure, which includes a fixing frame and connecting ribs. The fixing frame is rectangular, the connecting ribs have a serrated cross-section, and the height of the connecting ribs is the same as the height of the connecting ribs.
[0009] Furthermore, the silicone plate is rectangular and includes a buffer plate, a buffer chamber, and buffer particles. Multiple sets of buffer particles are evenly arranged on the surface of the buffer plate.
[0010] Furthermore, the distance between adjacent sets of buffer particles is consistent, and the bottom of the buffer plate is fixedly connected to the fixed frame.
[0011] Furthermore, the buffer particles are hemispherical structures made of silicone material, and the buffer plate has a buffer chamber inside, with the cross-section of the buffer chamber being rectangular.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This solution utilizes the smooth and soft surface of silicone, which prevents fruit from bouncing due to excessive hardness, reducing the risk of secondary impact. The corrugated fixing structure in the middle forms a wrinkled buffer layer, i.e., connecting ribs. When the silicone plate transmits impact force, the corrugated structure will further absorb energy through its own deformation, similar to the shock absorption principle of corrugated cardboard boxes, reducing noise. This forms a dual protection of flexible silicone buffer and secondary energy absorption by the corrugated structure, improving the buffering effect compared to single-material partition boards. It significantly reduces the instantaneous impact force on fruit, avoiding bruising, cracking, or scratches on the skin.
[0014] 2. This solution uses buffer particles to disperse the concentrated impact force of the fruit onto multiple protrusions. The compression deformation of individual particles absorbs some of the energy, reducing the impact force directly acting on the fruit's skin. This is especially suitable for fruits with extremely thin skins, such as strawberries and bayberries. The gaps between the buffer particles can form air escape channels, preventing the formation of a closed air pressure zone between the fruit's surface and the silicone plate during impact, thus reducing fruit bouncing caused by air pressure backlash. The compressibility of air extends the duration of the force: the dual buffer structure, combining buffer particles and buffer chambers, improves the impact absorption efficiency compared to a single silicone plate, significantly reducing the probability of fruit damage and breakage.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-9 This utility model provides a fruit conveying elevator, including an elevator body 1, a conveyor belt 2 installed on the elevator body 1, a material drop frame 3 fixedly installed at the end of the elevator body 1, a material distribution plate body 4 installed inside the material drop frame 3, a silicone plate 41 covering the surface of the material distribution plate body 4, a corrugated fixing structure 43 fixedly connected to the bottom of the silicone plate 41, and a PVC plate 42 fixedly connected to the bottom of the corrugated fixing structure 43.
[0027] Working principle: When the material distribution plate body 4 is in use, the conveyor belt 2 on the elevator body 1 is conveying the fruit. As the fruit falls, it impacts the material distribution plate body 4. The material distribution plate body 4 is composed of silicone plate 41, corrugated fixing structure 43 and PVC plate 42 distributed in layers from top to bottom. The surface layer of the material distribution plate body 4 is silicone plate 41, which is soft and can cushion the falling fruit, thus protecting the fruit.
[0028] In a preferred embodiment, the material distribution plate body 4 is composed of three parts: a silicone plate 41, a PVC plate 42, and a corrugated fixing structure 43. The silicone plate 41, the PVC plate 42, and the corrugated fixing structure 43 are arranged in layers.
[0029] The silicone sheet 41 and the PVC sheet 42 are fixed and supported by a corrugated fixing structure 43. The corrugated fixing structure 43 includes a fixing frame 431 and a connecting rib 432. The fixing frame 431 is rectangular, and the connecting rib 432 has a serrated cross-section. The height of the connecting rib 432 is the same as that of the connecting rib 432.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown: The material distribution plate body 4 adopts a layered combination design of silicone plate 41, corrugated fixing structure 43 and PVC plate 42, with the surface layer being silicone plate 41. This design offers multiple advantages during fruit impact, especially suitable for conveying fragile materials like fruit, reducing fruit damage rates. The silicone plate's flexible cushioning is its core function; its soft texture and excellent elasticity cause deformation upon fruit impact, significantly reducing the instantaneous impact force by prolonging the impact time, preventing bruising and cracking of the skin, such as in soft fruits like strawberries and peaches, or scratches on hard fruits like apples and pears. The smooth silicone surface and moderate coefficient of friction prevent excessive hardness from causing fruit to bounce, reducing the risk of secondary impacts. The corrugated fixing structure 43 in the middle forms a pleated cushioning layer, i.e., connecting ribs 432. When the silicone plate transmits impact force, the corrugated structure further absorbs energy through its own deformation, similar to the shock absorption principle of corrugated cardboard boxes, forming a flexible silicone cushioning effect. The dual protection of the corrugated structure and secondary energy absorption improves the buffering effect compared to a single-material distribution plate. The bottom PVC board 42 is hard and serves as a support layer to prevent excessive deformation of the overall structure, ensuring the angular stability of the distribution plate. At the same time, it disperses and transmits the remaining impact force, preventing excessive local stress from causing deformation of the distribution plate. The connecting ribs 432 on the corrugated fixing structure 43 are sawtooth-shaped. The sawtooth spacing of the connecting ribs 432 and the thickness of the PVC board 42 can be adjusted according to the load-bearing requirements of the distribution plate, making it suitable for single-batch large-flow fruit conveying or small-batch fine distribution scenarios. With the flexible buffer of the silicone board 41 as the core, it takes into account structural stability, hygiene and versatility: it maximizes the reduction of fruit impact damage through the combination of silicone board 41 and corrugated fixing structure 43, and ensures the reliable realization of the distribution function through PVC board 42. At the same time, it meets the safety and maintenance requirements of food processing, making it a highly efficient and adaptable design for the fruit elevator distribution process.
[0031] In a preferred embodiment, the silicone plate 41 is rectangular and includes a buffer plate 411, a buffer chamber 412, and buffer particles 413. Multiple sets of buffer particles 413 are uniformly disposed on the surface of the buffer plate 411.
[0032] The distance between two adjacent sets of buffer particles 413 is the same, and the bottom of the buffer plate 411 is fixedly connected to the fixed frame 431.
[0033] The buffer particle 413 is a hemispherical structure made of silicone material. The buffer plate 411 has a buffer chamber 412 inside, and the cross-section of the buffer chamber 412 is rectangular.
[0034] like Figure 8 and Figure 9As shown: Compared to a flat silicone surface, the buffer particles 413 can disperse the concentrated impact force of the fruit onto multiple protrusions. The compression deformation of individual particles absorbs some energy, reducing the impact force directly acting on the fruit skin, which is especially suitable for fruits with very thin skins such as strawberries and bayberries. The gaps between the buffer particles 413 can form air escape channels, preventing the formation of a closed air pressure zone between the fruit surface and the silicone plate 41 when the fruit is impacted, reducing the bouncing of the fruit due to air pressure backlash. The buffer chamber 412 inside the silicone plate 41 is the core force-dissipating structure: when the buffer particles 413 transmit the impact force to the silicone plate 41 body, the chamber will expand or contract due to pressure, further absorbing energy through the flow of internal air and silicone material. For example, when the chamber is a closed air chamber, the impact force will compress the air, using the compressibility of air to prolong the force's duration. The dual buffer structure, the combination of buffer particles 413 and buffer chamber 412, improves the impact force absorption efficiency compared to a single silicone plate 41, significantly reducing the probability of fruit damage and breakage.
