Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a flexible package upward conveying mechanism. Background Technology

[0002] Existing cabbage harvesting machines typically transport cabbages backward via a front conveyor mechanism after harvesting. This conveyor mechanism generally includes a lower sprocket conveyor, which comprises a frame and a longitudinal circulating conveyor belt. The longitudinal circulating conveyor belt is housed within the frame, and the spaced-apart first drive chains are connected by several parallel-spaced tubular shafts. In operation, the cabbages fall onto the conveyor belt and are transported backward. The main drawback of this conveyor mechanism is that the cabbages tend to roll on the conveyor belt instead of moving forward, resulting in low conveying efficiency. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by proposing a flexible package upward conveying mechanism that can significantly improve conveying efficiency.

[0004] The present invention achieves its technical objectives through the following technical solutions.

[0005] A flexible, upward-conveying mechanism is located at the front of a cabbage harvester and includes a lower sprocket conveyor. The lower sprocket conveyor includes a lower sprocket conveyor frame and a lower sprocket longitudinal circulating conveyor belt. The lower sprocket longitudinal circulating conveyor belt is housed within the lower sprocket conveyor frame. In the lower sprocket longitudinal circulating conveyor belt, first drive chains spaced apart are connected by several parallel-spaced tubular shafts. The improvement lies in the following: an upper sprocket conveyor is located above the lower sprocket conveyor. The upper sprocket conveyor includes an upper sprocket conveyor frame and an upper sprocket longitudinal circulating conveyor belt. The upper sprocket longitudinal circulating conveyor belt is housed within the upper sprocket conveyor frame. The upper sprocket conveyor and the lower sprocket conveyor are vertically aligned, and the lower conveying surface of the upper sprocket longitudinal circulating conveyor belt is spaced apart from the upper conveying surface of the lower sprocket longitudinal circulating conveyor belt.

[0006] Furthermore, in the longitudinal circulating conveyor belt of the upper sprocket, the second drive chains that are spaced apart are connected by several elastic belts.

[0007] Furthermore, the front part of the lower sprocket conveyor frame is hinged to the front part of the cabbage harvester base support frame, and push rods are provided in the lower and middle rear parts of the lower sprocket conveyor frame.

[0008] Compared with the prior art, this utility model has the following advantages:

[0009] 1. An upper sprocket conveyor is installed above the lower sprocket conveyor. The upper and lower sprocket conveyors are vertically aligned. The lower conveying surface of the upper sprocket longitudinal circulating conveyor belt is spaced apart from the upper conveying surface of the lower sprocket longitudinal circulating conveyor belt. In this way, during use, the cabbage will enter the conveying space formed by the spaced lower conveying surface of the upper sprocket longitudinal circulating conveyor belt and the upper conveying surface of the lower sprocket longitudinal circulating conveyor belt. It will be clamped and conveyed backward by the lower and upper conveying surfaces of the upper and lower sprocket longitudinal circulating conveyor belts. This will prevent the cabbage from rolling on the conveyor belt body composed of several parallel and spaced tube shafts and not moving forward, thus significantly improving the conveying efficiency.

[0010] 2. In the longitudinal circulating conveyor belt of the upper sprocket, the second drive chains that are spaced apart are connected by several elastic belts. In this way, the cabbage enters the conveying space formed by the lower conveying surface of the upper sprocket longitudinal circulating conveyor belt and the upper conveying surface of the lower sprocket longitudinal circulating conveyor belt, and is flexibly wrapped and conveyed backward, which significantly reduces the damage of the cabbage during the backward conveying process.

[0011] 3. The front part of the lower sprocket conveyor frame is hinged to the front part of the cabbage harvester base support frame. Push rods are provided in the lower and middle rear parts of the lower sprocket conveyor frame, so that the conveying angle can be adjusted by pushing rods. Attached Figure Description
