Novel thresher feeding flow control device

Abstract

The invention discloses a novel thresher feeding flow control device, and provides the novel thresher feeding flow control device with good flow control uniformity. The novel thresher feeding flow control device comprises a feeding pipe located above a feeding inlet of a thresher. The novel thresher feeding flow control device is characterized by further comprises a discharging device mounted at the lower end of the feeding pipe and three photoelectric sensors which are mounted on the feeding pipe at intervals in the length direction of the feeding pipe and used for detecting a material levelin the feeding pipe; the discharging device comprises a shell, two material-uniformizing conveyer belts which are vertically and parallelly mounted in the shell and correspondingly located on the twosides of the feeding pipe and a motor connected with the two material-uniformizing conveyer belts in a driving mode through a transmission mechanism; a plurality of material-uniformizing partition plates are arranged on the belt surfaces of the two material-uniformizing conveyer belts at intervals; and the material-uniformizing partition plates on the adjacent sides of the two material-uniformizing conveyer belts are close to each other. The novel thresher feeding flow control device is suitable for the feeding using of various threshers.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf stem separation equipment, in particular to a novel feed flow control device for a leaf topper. Background technique [0002] Leaf topper is one of the most critical equipment for separating tobacco leaves and stems, and its efficiency directly affects the effect of leaf tearing and leaf stem separation. There are many factors that affect the efficiency of beating and tearing leaves, among which the uniformity of materials is one of the most influential factors. However, there is no effective uniform feed control technology for toppers in the industry at present. [0003] In the leaf threshing process, the front length of the primary and secondary toppers uses a proportional feeder and uses the principle of friction rollers to distribute the materials. However, in the actual production process, it is difficult to ensure uniform material distribution because the tobacco leaves are long and in...

However, there is no effective uniform feeding control technology for leaf toppers in the industry at present

[0003] In the leaf threshing process, the front length of the primary and secondary toppers uses a proportional feeder and uses the principle of friction rollers to distribute the materials. However, in the actual production process, it is difficult to ensure uniform material distribution because the tobacco leaves are long and intertwined. Currently, manual The load of each leaf topper is monitored visually or through the current value of the roller, and then the tobacco leaf ratio is adjusted by manually adjusting the position of the friction roller. However, manual visual inspection is completely dependent on manual experience and is very unstable. In addition, it is also related to the state of the equipment itself. The current value alone cannot accurately reflect the load of the topper, so the actual deviation of the load of the first and second toppers is relatively large.

[0004] In the long-term practice of tobacco leaf production in the field of threshing and rebaking production, everyone has been focusing on the research on the blade of the leaf topper, the size and shape of the frame to improve the quality of tobacco leaf threshing. The uniformity of the leaf threshing process is based on experience to adjust the equipment, so the expected purpose and effect of tobacco leaf threshing control cannot be realized in the end. A technically critical and difficult issue with equipment manufacturers
