AI Technical Summary

Technical Problem

Traditional telescopic belt conveyors are prone to deviation and spillage during the transportation of bulk agricultural products, resulting in material loss and increased cleaning and maintenance costs. In addition, traditional material guide troughs cannot actively adjust the operating status of the belt conveyor.

Method used

A new type of telescopic belt conveyor was designed, which uses a guide rail and a sliding unit in conjunction with a folding inner core group. The guide rail guides the sliding unit to form a material flow guide groove, which constrains the material to converge to the center and prevents the belt from deviating when it deviates. The matching groove between the slide rod and the front conveyor roller forms a belt-type sprocket structure to improve transmission efficiency.

Benefits of technology

Effectively reduce material spillage, reduce losses, improve operational stability, reduce energy consumption, extend equipment life, and improve transmission efficiency.

Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product conveying equipment, and in particular to a novel telescopic belt conveyor. Background Art

[0002] The information disclosed in the background of the invention is only intended to enhance understanding of the overall background of the invention and should not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0003] At present, telescopic belt conveyors are widely used in the transportation of bulk materials, such as agricultural products and fertilizers. In actual use, the belt may shift due to uneven tension or structural design defects during the expansion or dynamic adjustment process, resulting in the inability to concentrate the bulk agricultural products. Moreover, during high-speed material drop, the material diffuses due to inertia and easily exceeds the coverage range of the baffle. In particular, "spillage" is more likely to occur in the end area of ​​the telescopic section, which not only causes a large amount of material loss, but also increases the subsequent cleaning and maintenance costs, reduces production efficiency, and may also affect the surrounding environment and the safety of workers. Traditional belt conveyor material guide troughs are mostly fixed structures, and the operating status of the telescopic belt conveyor cannot be actively adjusted.

[0004] Therefore, there is an urgent need to study a conveying device that can effectively solve the problems of deviation and "sprinkling belt" that occur in the process of conveying bulk agricultural products by a telescopic belt conveyor. Summary of the Invention

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a new telescopic belt conveyor, which aims to solve the problems of traditional telescopic belt conveyors being prone to deviation due to uneven tension during the telescopic process and serious material spillage during high-speed blanking.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions: A novel telescopic belt conveyor comprises a frame body and a front telescopic section. The front telescopic section is freely retracted and extended under the drive of a driving device, driving the conveying length of the conveyor belt to change synchronously. The front telescopic section is provided with a front conveying roller. A plurality of spaced-apart mounting cavities are provided on one side of the conveyor belt and the front conveyor roller, each of which is provided with a corresponding slide rod, and a corresponding folding inner core group is installed in the mounting cavity, the folding inner core group including two folding inner core bodies arranged in a left-right direction, the fixed ends of the folding inner core bodies close to the outer sides are fixed to the conveyor belt, and the other movable ends are fixedly installed on the corresponding sliding units; The sliding units are all slidably installed on the corresponding sliding rods. At the same time, the sliding units are also slidably installed on the guide rails. The guide rails cooperate with the sliding units to provide support for the conveyor belt and assist in preventing deviation positioning. The guide rails also guide the sliding units to start moving toward the left and right ends of the front conveyor roller near the front conveyor roller, so as to realize the corresponding folding inner core group folding to the left and right sides near the front conveyor roller to form a material flow guide groove.

[0007] Preferably, the sliding unit comprises a sliding frame, the upper end of which is fixedly mounted on the movable end of the corresponding folding inner core body; The slide bar is provided with a first slide groove adapted to the first slide block; The bottom of the sliding frame is provided with a second sliding block or pulley adapted to be slidably mounted on the guide rail.

[0008] Preferably, the upper end of the sliding frame is provided with a connecting block which is fixedly mounted to the corresponding folding inner core body.

[0009] Preferably, the installation cavity is provided with an open-hole slideway for cooperating with the connecting block for sliding.

[0010] Preferably, the slide bar is provided with a base for being mounted and fixed on a conveyor belt.

[0011] Preferably, the guide rail comprises a straight section, a guide folding section and an end return section, and the straight section comprises a plurality of guide rail units that are assembled in a telescopic and nested manner.

[0012] Preferably, the front conveying roller is rotatably mounted on the support frame via a mounting shaft; The end return section is mounted and fixed on the support frame.

[0013] Preferably, both the straight section and the guide folding section can be mounted on the corresponding frame body via a support rod.

[0014] Preferably, the front conveying roller is provided with a matching groove adapted to the sliding rod.

[0015] The present invention has at least the following beneficial effects: In the present invention, the guide rail guides the sliding unit to start moving toward both ends near the front conveyor roller, prompting the folded inner core group to fold toward both sides to form a material flow guide groove, effectively restraining and guiding the material to converge toward the center of the conveyor belt, reducing the "scattering" phenomenon of bulk agricultural products and reducing the loss of agricultural products.

[0016] In the present invention, due to the restraining effect of the guide rail on the sliding unit and the connection relationship between the sliding unit and the folding inner core body, when the conveyor belt deviates to the left or right, the folding inner core body can play a pulling role, effectively preventing the belt from continuing to deviate and ensuring operational stability.

[0017] In addition, the present invention also has the following technical effects: The additional support provided by the sliding unit and guide rails reduces the curvature between the rollers, thereby reducing the power required for the drive unit and reducing energy consumption. At the same time, this also slows down the wear rate of the belt and rollers, extending the service life of the equipment.

[0018] The conveyor belt, through the matching grooves between the sliding rod and the front conveyor roller, forms a "belt-type sprocket" structure. This combines the flexibility of a traditional belt with the strong driving force of a sprocket drive, reducing slippage and deviation. Compared to traditional belt conveyors that rely on friction for transmission, this design significantly improves transmission efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0022] Figures 1 to 6 A novel telescopic belt conveyor is presented, comprising a frame body 100 and a front telescopic section 200. The front telescopic section 200 is freely retracted and extended under the drive of a driving device, driving the conveying length of a conveyor belt 230 to change synchronously; the front telescopic section 200 is provided with a front conveying roller 220.

[0023] The side of the conveyor belt 230 that mates with the front conveyor roller 220 is provided with a plurality of spaced mounting cavities 231. Each mounting cavity 231 is provided with a corresponding slide bar 237. The slide bar 237 has a base 236 for mounting and fixing to the conveyor belt 230. In addition, the slide bar 237 is preferably a cylindrical slide bar 237. The front conveyor roller 220 is provided with a mating groove 221 adapted to fit the slide bar 237. In this way, as the conveyor belt is conveyed, the slide bar 237 also engages with the mating groove 221, forming a belt-type sprocket effect. Due to the inherent flexibility of the conveyor belt 230, the above-mentioned belt has both appropriate flexibility and strong conveying force.

[0024] A corresponding folding inner core group is installed in the installation cavity 231. The folding inner core group includes two folding inner core bodies 232 arranged in the left and right directions. The fixed ends of the folding inner core bodies 232 close to the outside are fixed on the conveying belt 230, and the other movable ends are fixedly installed on the corresponding sliding units. The sliding units are slidably installed on the corresponding sliding rods 237. At the same time, the sliding units are also slidably installed on the guide rail 300. The guide rail 300 cooperates with the sliding unit to provide support for the conveying belt 230 and prevent deviation positioning in the lateral direction.

[0025] The material selection of the folding core must take into account functionality such as flexibility, strength, and durability. Materials such as polyurethane, nylon, or suitable rubber can be selected.

[0026] Because the rollers of a conveyor belt are prone to bending due to the weight of the material, the drive requires greater power to maintain proper belt operation, increasing energy consumption. This also accelerates belt wear and wear, accelerating damage to the rollers, shortening the life of the equipment. The support provided by the sliding unit and guide rails 300 in the aforementioned structure not only provides a predetermined guide for the sliding unit, thereby driving the folding core to fold sideways, but also addresses these issues simultaneously.

[0027] At the same time, since the guide rail 300 has a restraining effect on the sliding unit, and the sliding unit is fixedly connected to one end of the folding inner core, when the conveyor belt 230 deviates to the left or right, it will be pulled by one of the folding inner core bodies 232 in a group of folding inner core groups to prevent it from deviating, effectively preventing the belt from continuing to deviate and ensuring operational stability.

[0028] The guide rail 300 also guides the sliding unit to start moving toward the left and right ends of the front conveying roller 220 near the front conveying roller 220, so as to realize the corresponding folding inner core group to fold to the left and right sides near the front conveying roller 220, forming a material flow guide groove, that is, a "V-shaped" or "trapezoidal" guide groove, which actively restrains and guides the material in the end area of ​​the telescopic section, so that the agricultural product material converges to the center of the conveyor belt to prevent it from being thrown to both sides of the conveyor belt.

[0029] The specific structure of the sliding unit and its connection method are as follows: it includes a sliding frame 234, the upper end of which is fixedly installed on the movable end of the corresponding folding inner core body 232; the sliding rod 237 is provided with a first sliding groove 2371 adapted to the first sliding block, and the bottom of the sliding frame 234 is provided with a second sliding block or pulley 235 adapted to the guide rail 300 for sliding installation.

[0030] The upper end of the sliding frame 234 is provided with a connecting block 233 fixedly mounted with the corresponding folding inner core body 232; the mounting cavity 231 is provided with an open slideway for cooperating with the connecting block 233 to slide.

[0031] The specific configuration of the guide rail 300 is as follows: it includes a straight section, a guide folding section and an end return section. The straight section includes multiple retractable nested assembled guide rail 300 units (not shown in the figure). If it is designed as a drawer-type segment, it can be independently pulled out for maintenance when a single segment fails, which is very easy to implement and will not be further elaborated here.

[0032] The front end conveying roller 220 is rotatably mounted on the support frame 210 via the mounting shaft; the guide rail 300 is installed as follows: the end return section is mounted and fixed on the support frame 210, and the straight section and the guide folding section can both be mounted on the corresponding frame body 100 via the support rod 400.

[0033] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.
