Description

TECHNICAL FIELD

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

[0002] The information disclosed in the background of the present application is only intended to increase the understanding of the overall background of the present application and should not necessarily be regarded as acknowledging or implicitly suggesting that this information constitutes prior art known to those of ordinary skill in the art.

[0003] At present, telescopic belt conveyors are widely used in the conveying of bulk materials such as agricultural products and fertilizers. In actual use, the belt may deviate during telescoping or dynamic adjustment due to uneven tension or design defects, resulting in the failure of bulk agricultural materials to be concentrated. Moreover, when the material falls at high speed, the material may spread due to inertia, easily exceeding the coverage range of the baffle, especially at the end of the telescopic section, which is more likely to cause "spreading and scattering", not only causing a large amount of material loss, but also increasing the subsequent cleaning and maintenance costs, reducing production efficiency, and possibly affecting the surrounding environment and the safety of workers. The traditional belt conveyor guide chute is of a fixed structure and cannot actively adjust the running state of the telescopic belt conveyor.

[0004] Therefore, it is urgent to research a conveying device that can effectively solve the problems such as deviation and "spreading and scattering" of the telescopic belt conveyor during the conveying of bulk agricultural materials. SUMMARY

[0005] In view of the problems existing in the prior art, the purpose of the present application is to provide a novel telescopic belt conveyor, which aims to solve the problems such as easy deviation of the traditional telescopic belt conveyor during telescoping due to uneven tension and serious material scattering when the material falls at high speed.

[0006] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0007] A novel telescopic belt conveyor, comprising a rack main body and a front telescopic section, the front telescopic section is freely telescoped under the drive of a drive device, driving the synchronous change of the conveying length of the conveying belt; the front telescopic section is provided with a front end conveying roller;

[0008] A plurality of installation cavities are arranged on one side of the conveying belt matched with the front end conveying roller, each installation cavity is provided with a corresponding sliding rod, a corresponding folding inner core group is installed in the installation cavity, the folding inner core group comprises two folding inner core main bodies arranged in left and right directions, the fixed end of the folding inner core main body close to the outer side is fixed on the conveying belt, and the other end movable end is fixedly installed on the corresponding sliding unit;

[0009] The sliding units are slidably installed on the corresponding slide rods, and meanwhile, the sliding units are also slidably installed on the guide rails, the guide rails cooperate with the sliding units to provide support and auxiliary anti-deviation positioning for the conveying belt, and the guide rails also guide the sliding units to start moving towards the left and right ends of the front end conveying roller near the front end conveying roller to realize folding of the corresponding folding inner core groups to the left and right sides near the front end conveying roller to form a material flow guide groove.

[0010] Preferably, the sliding unit comprises a sliding frame, and the upper end of the sliding frame is fixedly installed with the movable end of the corresponding folding inner core body.

[0011] The slide rod is provided with a first sliding groove matched with the first sliding block.

[0012] The bottom of the sliding frame is provided with a second sliding block or a pulley slidably installed with the guide rail.

[0013] Preferably, the upper end of the sliding frame is provided with a connecting block fixedly installed with the corresponding folding inner core body.

[0014] Preferably, the installation cavity is provided with an opening sliding channel for sliding cooperation with the connecting block.

[0015] Preferably, the slide rod is provided with a base for fixed installation on the conveying belt.

[0016] Preferably, the guide rail comprises a straight running section, a guide folding section and an end return section, and the straight running section comprises a plurality of telescopic nested guide rail units.

[0017] Preferably, the front end conveying roller is rotatably installed on the support frame through an installation shaft.

[0018] The end return section is fixedly installed on the support frame.

[0019] Preferably, the straight running section and the guide folding section are both installed on the corresponding rack body through a support rod.

[0020] Preferably, the front end conveying roller is provided with a matching groove matched with the slide rod.

[0021] The present application at least has the following beneficial effects:

[0022] In the present application, the guide rail guides the sliding unit to start moving towards the two ends near the front end conveying roller, so as to make the folding inner core group fold to the two sides to form a material flow guide groove, effectively constrain and guide the material to converge to the center of the conveying belt, reduce the "throwing" phenomenon of the bulk material of agricultural products, and reduce the loss of agricultural product materials.

[0023] The constraint of the guide rail on the sliding unit and the connection relationship between the sliding unit and the folding inner core body in the application can play a pulling role when the conveying belt deviates left and right, effectively prevent the belt from continuing to deviate, and ensure the running stability.

[0024] In addition, the application also has the following technical effects:

[0025] The additional support provided by the sliding unit and the guide rail reduces the bending arc between the carrier rollers, thereby reducing the power required by the driving device and reducing energy consumption. At the same time, this also slows down the wear speed of the belt and the carrier roller, prolonging the service life of the equipment.

[0026] The conveying belt forms a "belt type chain wheel" structure through the cooperation of the sliding rod and the matching groove of the front end conveying roller, which has the flexibility of traditional belts and the strong driving force of chain wheel transmission, reducing slipping and deviation. Compared with the mode of relying on friction force transmission of the traditional belt machine, the design can significantly improve the transmission efficiency. BRIEF DESCRIPTION OF DRAWINGS
