Description

Technical Field

[0001] This utility model relates to the technical field of pickup machine accessories, specifically to a pickup machine with an assemblable metal transmission belt. Background Technology

[0002] Due to climatic reasons, crops need to be covered with plastic film for insulation and moisture retention. After harvesting, the plastic film cannot decompose on-site. A soil collector can efficiently recycle the film from the soil, restoring fertile land and generating income for farmers. In some areas with abundant sand and gravel, the soil collector encounters impacts from stones during operation, placing a significant impact load on the collector's drive belt. With the increasing size, intelligence, and automation of soil collectors, and the continuous improvement of agricultural machinery efficiency, the drive belts currently used in soil collectors can no longer meet the requirements of high-intensity operations. Under high impact loads, the belt is prone to breakage, deformation, and accelerated damage. Furthermore, customers drilling holes in the soil collector's drive belt and adding metal parts increase localized stress, accelerating tearing and breakage at the perforation points. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a conveyor belt for a pickup machine that can be fitted with metal parts. It employs a layered structure to enhance the strength of the conveyor belt body, while also preventing tearing and breakage when metal parts are installed, thus effectively extending the service life of the conveyor belt.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a conveyor belt for a pickup machine that can be fitted with metal parts, comprising a conveyor belt body, the conveyor belt body comprising a compression layer and a reinforcing layer, the compression layer and the reinforcing layer being provided with a wrapping layer, the conveyor belt body being provided with through holes for mounting metal parts, the reinforcing layer comprising multiple splicing layers one, and the compression layer comprising multiple splicing layers two.

[0005] As a further improvement to the above technical solution:

[0006] The first splicing layer includes a first substrate, and the second splicing layer includes a second substrate. Both the first substrate and the second substrate have an adhesive layer on their two sidewalls.

[0007] The first substrate is made of aramid fabric, and the second substrate is made of wide-angle aramid fabric.

[0008] The thickness of the first splicing layer and the second splicing layer is 0.9-1.3 mm.

[0009] The wrapping layer includes a substrate three, and an adhesive layer two is provided on both sidewalls of the substrate three.

[0010] The third substrate is made of polyester-cotton blended fabric, and the thickness of the wrapping layer is 0.6-0.8 mm.

[0011] The number of through holes is multiple, and each through hole is opened along the thickness direction of the transmission belt body.

[0012] The beneficial effects of this utility model embodiment are as follows: The pickup machine uses a transmission belt that can be fitted with metal parts, including a transmission belt body, the transmission belt body includes a compression layer and a reinforcing layer, the compression layer and the reinforcing layer are provided with a wrapping layer, the transmission belt body is provided with through holes for installing metal parts, the reinforcing layer includes multiple splicing layers one, the compression layer includes multiple splicing layers two, compared with the existing transmission belt with a rope structure as the reinforcing layer, it has better strength, and the multi-layer wide-angle aramid cloth is used as the compression layer structure of the transmission belt. By changing the splicing angle, the compression layer structure has small resistance to lateral compression deformation and good longitudinal bending performance, and the belt body is not easily deformed under impact load transmission;

[0013] By utilizing a layered structure to manufacture the transmission belt body, the aramid fabric belt becomes smaller, and the multi-layer aramid fabric transmission belt is less prone to tearing and breakage after perforation and installation of metal parts. Attached Figure Description

[0019] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] like Figure 1 As shown, the pickup machine in this embodiment uses a conveyor belt with assembleable metal parts, including a conveyor belt body 1. The conveyor belt body 1 includes a compression layer 2 and a reinforcing layer 3. The compression layer 2 and the reinforcing layer 3 are provided with a wrapping layer 12. The conveyor belt body 1 is provided with through holes 4 for mounting metal parts. The reinforcing layer 3 includes multiple splicing layers 5, and the compression layer 2 includes multiple splicing layers 6.

[0021] like Figure 2-3As shown, splicing layer 5 includes substrate 7, and splicing layer 6 includes substrate 8. Adhesive layer 9 is provided on both side walls of substrate 7 and substrate 8. Substrate 7 is made of aramid fabric, and substrate 8 is made of wide-angle aramid fabric. The compression layer structure of the transmission belt is made of multi-layer wide-angle aramid fabric. By changing the splicing angle, the compression layer structure has small resistance to lateral compression deformation and good longitudinal bending performance. The belt body is not easily deformed under impact load transmission.

[0022] The thickness of splicing layer 5 and splicing layer 6 is 1 mm, the base material 3 10 is made of polyester-cotton blended fabric, and the thickness of wrapping layer 12 is 0.7 mm, which facilitates wrapping compression layer 2 and reinforcing layer 3.

[0023] The wrapping layer 12 includes a substrate 3 10, and an adhesive layer 2 11 is provided on both sidewalls of the substrate 3 10.

[0024] like Figure 4 As shown, there are multiple through holes 4, and each through hole 4 is opened along the thickness direction of the transmission belt body 1.

[0025] Taking type B V-belts as an example, polyester cord V-belts typically have 7-8 5*3 cords, while aramid fabric V-belts have 8 layers of aramid rubbery cloth. A comparison of the main performance characteristics of polyester cord V-belts and aramid fabric V-belts is shown below:

[0026] model Polyester cord structure type B Aramid white grey fabric structure type B Tensile strength / kN 6.8 22.3 Reference force elongation / % 3.7 0.9

[0027] The resulting conveyor belt for pickup machines, designed using the above method, boasts a strength more than three times higher than that of similar conveyor belts. By employing a multi-layered, wide-angle aramid fabric as the compression layer structure, and through angled splicing, the compression layer structure exhibits minimal lateral compression deformation and excellent longitudinal flexural performance, making the belt less prone to deformation under impact loads. Furthermore, the aramid fabric's minimal deformation means that the multi-layered aramid fabric conveyor belt is less susceptible to tearing when perforated to accommodate metal parts.
