Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically to a flexible conveyor belt for a harvester. Background Technology

[0002] Currently, harvesters specifically designed for harvesting various fresh crops are gradually appearing on the market. However, traditional harvesters primarily rely on mechanical chain rakes for conveying during the harvesting process, which damages crops, resulting in a high rate of crop damage, low product prices, and consequently, lower profits. Therefore, rubber conveyor belts are being used as a replacement, offering higher transmission efficiency and a lower breakage rate.

[0003] However, flexible rubber conveyor belts have low conveying efficiency. Since rubber conveyor belts mostly have smooth conveying surfaces, they cannot evenly divide and transport fresh crops. Secondly, although some conveyor belts have added dividing strips on their surface, due to long-term use and the squeezing of fresh crops, the dividing strips may crack at the edges or even fall off, affecting the stability and lifespan of the belt. Utility Model Content

[0004] This utility model proposes a flexible conveyor belt for harvesters, which solves the problem in the prior art that the partition bars of flexible conveyor belts for harvesters are prone to cracking and damage, affecting the conveying efficiency, stability and service life.

[0005] The technical solution of this utility model is as follows:

[0006] A flexible conveyor belt for a harvester includes a base rubber layer, a substrate layer, and multiple rubber strip edges. The substrate layer is disposed on the base rubber layer, and the multiple rubber strip edges are evenly spaced along the length of the substrate layer. The flexible conveyor belt also includes a pre-embedded skeleton, which includes a stabilizing part and a supporting part. The stabilizing part is disposed within the substrate layer, and the supporting part is disposed within the rubber strip edges. The supporting part and the stabilizing part form a T-shaped structure.

[0007] The support portion is also provided with a plurality of connecting portions, which are located on both sides of the support portion.

[0008] The joint is inclined toward the side of the stabilizing part.

[0009] Both sides of the connection between the adhesive strip edge and the substrate layer are rounded.

[0010] The cross-section of the rubber strip along its width direction is trapezoidal.

[0011] The edge of the adhesive strip is also covered with a layer of adhesive tape.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] This utility model discloses a flexible conveyor belt for a harvester. A base layer is formed on a bottom rubber layer, and multiple rubber strips are evenly spaced along the length of the base layer. These rubber strips divide the area, ensuring even distribution of fresh crops. An embedded skeleton is also provided within the base layer and the rubber strips. The embedded skeleton is an integrated structure divided into two parts: one part is embedded within the base layer, and the other part is a support portion located within the rubber strips. The support portion enhances the strength of the rubber strips and forms a T-shaped layout with a stabilizing part, invertedly embedded within the base layer and rubber strips. The stabilizing part is horizontally embedded within the base layer, while the support part is vertically protruding outside the base layer. The rubber strips wrap around the support portion. When there are fresh crops on both sides of the rubber strips, the support portion, connected by the stabilizing part, provides support to the rubber strips, improving their resistance to compression, extending their service life, and to a certain extent preventing the rubber strips from cracking, falling off, or peeling, thus maintaining the stability of the conveyor belt.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1-4As shown in the figure, this embodiment proposes a flexible conveyor belt for a harvester. The flexible conveyor belt includes a base rubber layer 1, a base layer 2, and a plurality of rubber strip edges 3. The base layer 2 is disposed on the base rubber layer 1, and the plurality of rubber strip edges 3 are arranged at equal intervals along the length direction of the base layer 2. The flexible conveyor belt also includes a pre-embedded skeleton 4, which includes a stabilizing part 5 and a supporting part 6. The stabilizing part 5 is disposed in the base layer 2, and the supporting part 6 is disposed in the rubber strip edges 3. The supporting part 6 and the stabilizing part 5 form a T-shaped structure.

[0022] In this embodiment, a substrate layer 2 is provided on the base adhesive layer 1. Multiple adhesive strip ridges 3 are evenly spaced along the length of the substrate layer 2, dividing the area and ensuring even distribution of the fresh crops. An embedded skeleton 4 is also provided within the substrate layer 2 and the adhesive strip ridges 3. The embedded skeleton 4 is an integral structure divided into two parts: one part is embedded within the substrate layer 2, and the other part is a support 6 located within the adhesive strip ridges 3. The support 6 enhances the strength of the adhesive strip ridges 3, and the support 6 forms a shape with the stabilizing part 5. The structure is arranged in a T-shape and is inverted and embedded in the substrate layer 2 and the adhesive strip ridge 3. In one embodiment, the stabilizing part 5 is a straight structure and the supporting part 6 is also a straight structure. The supporting part 6 and the stabilizing part 5 are perpendicular to each other. The stabilizing part 5 is a part that is horizontally embedded in the substrate layer 2, and the supporting part 6 is a part that is vertically protruding outside the substrate layer 2. The adhesive strip ridge 3 is wrapped around the outside of the supporting part 6. When there are fresh crops on both sides of the adhesive strip ridge 3, the supporting part 6 provides support for the adhesive strip ridge 3 under the connection of the stabilizing part 5.

[0023] In other possible embodiments, the pre-embedded skeleton 4, the stabilizing part 5 still adopts a straight structure, while the supporting part 6 adopts an umbrella-shaped layout structure, with a vertical structure in the middle and then the two sides are bent into a U-shaped structure with the opening facing downward. In addition to providing support for the rubber strip edge 3, the supporting part 6 can also provide a certain amount of rebound force on both sides, improve the deformation resistance of the rubber strip edge 3, and extend its service life.

[0024] The support portion 6 is also provided with a plurality of connecting portions 7, which are located on both sides of the support portion 6.

[0025] The connecting part 7 is inclined toward the side of the stabilizing part 5.

[0026] Based on the above embodiments, the support part 6 is provided with a connecting part 7 to improve the tightness of the bonding with the adhesive strip ridge 3. The connecting part 7 is on both sides of the support part 6. When the adhesive strip ridge 3 is formed, it is plastically bonded to the connecting part 7 to form a fit, thereby improving the tightness of the bonding with the support part 6. Furthermore, the connecting part 7 can also be set at an angle inclined towards the stabilizing part 5, so that the bonding between the adhesive strip ridge 3 and the base layer 2 is more reliable and peeling off is avoided.

[0027] Both sides of the connection between the adhesive strip edge 3 and the substrate layer 2 are rounded.

[0028] Based on the above embodiments, after the connection between the rubber strip 3 and the base layer 2 is formed, the right-angle connection between the bottom two sides of the rubber strip 3 and the base layer 2 is optimized to rounded corners. After optimization, it can adapt to deformation during operation and extrusion of fresh crops to avoid bottom cracking.

[0029] The cross-section of the rubber strip edge 3 along its width direction is trapezoidal.

[0030] Based on the above embodiments, the cross section of the rubber strip 3 is set as a trapezoidal structure. When fresh crops are placed into the rubber strip 3 area on the conveyor belt, the inclined grid structure can disperse the squeezing force.

[0031] The edge 3 of the adhesive strip is also covered with an adhesive tape bonding layer 8.

[0032] Based on the above embodiments, a layer of adhesive tape 8 is wrapped around the outside of the rubber strip edge 3 to improve the wear resistance of the rubber strip edge 3.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
