[0035] Please refer to Figure 1 and Figure 2 This embodiment provides a non-powered roller conveyor 100, which includes a frame 110, a guardrail 120, multiple rollers 130 and multiple wheels 140.

[0036] Guardrails 120 are arranged on opposite sides of the frame 110 to form a slide 101 extending in a preset direction; the height of the slide 101 gradually decreases from one end to the other.

[0037] Multiple rollers 130 are rotatably connected to the slide rail 101 and are arranged parallel and spaced apart along a preset direction to make rolling contact with the goods in the slide rail 101.

[0038] Multiple rollers 140 are connected to the bottom of the frame 110 and distributed around the frame 110 to make rolling contact with the ground.

[0039] Please refer to Figure 1 and Figure 2 The working principle of the unpowered roller conveyor 100 is as follows:

[0040] The non-powered roller conveyor 100 includes a frame 110, guardrails 120, multiple rollers 130, and multiple wheels 140. The guardrails 120 are arranged on opposite sides of the frame 110 to form a slide 101 extending in a preset direction. The height of the slide 101 gradually decreases from one end to the other. The multiple rollers 130 are rotatably connected to the slide 101 and are arranged parallel and spaced apart in a preset direction to make rolling contact with the goods in the slide 101. As a result, since the slide 101 adopts an uneven height, i.e., inclined arrangement, the material can slide from high to low under the action of its gravity after entering the slide 101, thus sliding along the slide 101 without the assistance of external force. This can play the role of transferring and conveying materials. Moreover, this arrangement simplifies the structural design and reduces the labor intensity of the workers.

[0041] In addition, multiple rollers 140 are connected to the bottom of the frame 110 and distributed around the frame 110 to make rolling contact with the ground. Thus, during use, they can be moved to appropriate positions according to the needs of use, so as to facilitate rapid material transfer. Therefore, the unpowered roller conveyor 100 has a simple structure and is flexible and convenient to use. It can reduce the labor intensity of workers and improve the efficiency of material transfer.

[0042] Further, please refer to Figure 1 and Figure 2 During use, in order to adjust the inclination of the slide 101 according to the needs of use, the falling speed of the material after entering the slide 101 can be adjusted, and the height of the end of the slide 101 used for material entry can meet the actual needs of use. Therefore, the frame 110 includes a movable frame 111, a slide plate 112 and a lifting frame 113.

[0043] Multiple rollers 140 are connected to the movable frame 111; one end of the slide plate 112 along a preset direction is rotatably connected to the movable frame 111; the lifting frame 113 is connected to the movable frame 111 and is used to drive the other end of the slide plate 112 to move vertically relative to the movable frame 111.

[0044] In this way, the height of one end of the slide 101 can be adjusted via the lifting frame 113 to regulate the material conveying speed. Simultaneously, it facilitates material loading at the material entry end of the slide 101. Specifically, the lifting frame 113 includes at least two lifting rods 114, each with two hinge seats 115 at both ends. The two hinge seats 115 are respectively connected to the movable frame 111 and the slide plate 112. The two lifting rods 114 are spaced apart and connected to the same end of the slide plate 112. It should be noted that the lifting rods 114 are adjustable in length and can be existing hydraulic or pneumatically driven telescopic rod structures.

[0045] Furthermore, in this embodiment, to improve the stability of the material during the conveying process and reduce the noise during the material sliding within the slide 101, the unpowered roller conveyor 100 also includes multiple conveyor belts 150. These multiple conveyor belts 150 are spaced apart along a preset direction, and each conveyor belt 150 is fitted onto at least two rollers 130. The configuration of the conveyor belts 150 can be adjusted according to actual usage requirements; that is, their number and placement can be modified as needed.

[0046] Taking the configuration of three conveyor belts 150 as an example, the unpowered roller conveyor 100 includes a first conveyor belt 151, a second conveyor belt 152 and a third conveyor belt 153 arranged at intervals along a preset direction.

[0047] The first conveyor belt 151 is fitted onto a first preset number of rollers 130, the second conveyor belt 152 is fitted onto a second preset number of rollers 130, and the third conveyor belt 153 is fitted onto a third preset number of rollers 130; wherein the first preset number, the second preset number, and the third preset number are all greater than 2, and the first preset number, the second preset number, and the third preset number increase sequentially.

[0048] This configuration uses three conveyor belts 150, namely the first conveyor belt 151, the second conveyor belt 152, and the third conveyor belt 153. To improve the stability of the first conveyor belt 151, the second conveyor belt 152, and the third conveyor belt 153, the number of rollers 130 fitted on the first conveyor belt 151, the second conveyor belt 152, and the third conveyor belt 153 can be different. For example, the first conveyor belt 151 can be fitted with two rollers 130, the second conveyor belt 152 can be fitted with three rollers 130, and the third conveyor belt 153 can be fitted with four rollers 130.

[0049] Furthermore, in configuring the first conveyor belt 151, the second conveyor belt 152, and the third conveyor belt 153, this embodiment adopts the arrangement of the first conveyor belt 151, the second conveyor belt 152, and the third conveyor belt 153 in the direction of decreasing height of the slide 101.

[0050] Furthermore, as described above, when the inclination of the slide 101 is relatively large, dampers are installed at some of the rotational connections between the rollers 130 and the frame 110 to prevent the material from moving too fast within the slide 101. The dampers reduce the speed of the material during sliding. The dampers can be existing types of dampers, or they can be configured as gearboxes with the same structure as existing technology, which will not be described further here.

[0051] Taking the above-mentioned arrangement of a first conveyor belt 151, a second conveyor belt 152, and a third conveyor belt 153 as an example, when it is necessary to decelerate the conveyor belt, at least one of the multiple rollers 130 covered by the first conveyor belt 151, at least one of the multiple rollers 130 covered by the second conveyor belt 152, and at least one of the multiple rollers 130 covered by the third conveyor belt 153 can be provided with a damper at their rotational connection with the frame 110.

[0052] Further, please refer to Figure 1 and Figure 2 In this embodiment, in order to prevent the material from being damaged due to friction between the material and the sides of the slide 101 when the material slides in the slide 101, guide wheels 116 are rotatably provided on both sides of the slide 101 along a preset direction.

[0053] To facilitate material loading and unloading, guide plates 117 connected to the frame 110 are provided at both ends of the slide 101 along a preset direction. The guide plates 117 can be rotatably connected to the frame 110, the purpose of which is to allow for angle adjustment according to usage requirements, thereby improving the convenience of loading and unloading.

[0054] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
