Air-ejected anti-blocking system for cane harvester

Abstract

The invention discloses an air-ejected anti-blocking system for a cane harvester. The air-ejected anti-blocking system comprises a harvester body. The harvester body is provided with sucking channels for sucking and discharging smashed leaves. The harvester body is provided with an air compressor and an air storage tank. In the harvester body, first air nozzles are arranged on portions, where blocking occurs easily, of cane stalk conveying paths. Multiple second air nozzles are arranged in the sucking channels in the sucking channel direction. The first air nozzles and the second air nozzles are communicated with the air storage tank through pipelines. Blocking inductors are arranged beside the first air nozzles and the second air nozzles. As an air-ejected anti-blocking device is additionally arranged, when blocking occurs, by means of high-pressure air ejection, blockages are ejected out in the sucking channel direction in time, it is ensured that the leaves are sucked out of the harvester at the highest speed, the interiors of leaf stripping channels and the interiors of the sucking channels are prevented from being blocked, and normal harvesting work of the cane harvester is ensured.

Description

Technical field: [0001] The invention relates to an air jet anti-blocking system for a sugarcane harvester. Background technique: [0002] The sugarcane planting area in my country is relatively large, and the harvest season of sugarcane is from October to January of the next year. After the sugarcane matures, it must be harvested within one or two months, otherwise the sugarcane will produce sugar back, that is, its sugar content will be lost. In order to be able to harvest sugarcane within a limited time, various sugarcane harvesters have emerged as the times require. After the sugarcane harvester cuts off the sugarcane stalk, it needs to peel off the leaves on the sugarcane stalk. The traditional sugarcane harvester is There are many pairs of peeling wheels in the body, and the leaves on the sugarcane stalks are peeled off by using the pairs of stripping impellers.

[0002] The sugarcane planting area in my country is relatively large, and the harvest season of sugarcane is from October to January of the next year. After the sugarcane matures, it must be harvested within one or two months, otherwise the sugarcane will produce sugar back, that is, its sugar content will be lost. In order to be able to harvest sugarcane within a limited time, various sugarcane harvesters have emerged as the times require. After the sugarcane harvester cuts off the sugarcane stalk, it needs to peel off the leaves on the sugarcane stalk. The traditional sugarcane harvester is There are many pairs of peeling wheels in the body, and the leaves on the sugarcane stalks are peeled off by using the pairs of stripping impellers. After the leaves on the sugarcane stalks are stripped, they need to be crushed immediately, otherwise the cane leaves will be entangled in the harvester. On the parts, more and more entanglements will finally block the leaf stripping channel completely, resulting in the harvester not working properly

The current sugarcane harvester uses suction to discharge the blades, but its efficiency is very low in actual work. The reason is that the leaf stripping components of the general sugarcane harvester are arranged along the direction of sugarcane transmission and consist of multiple sets of stripping wheels. A stripping channel unit, and the stripped cane leaves are theoretically pumped out through the ventilation system, but in practice this method is obviously not enough, because only from the structural analysis of the sugarcane stripping channel , the sugarcane leaf stripping channel is a square pipe structure, and multiple groups of sugarcane stripping wheel shafts are arranged horizontally inside the square pipe, then after the sugarcane leaves are stripped, they will rotate along the rotation momentum of the stripping wheel. The impeller shafts are arranged horizontally, with a length of about 500mm, and the exhaust fan of the exhaust system is set at the end of the channel. When the exhaust fan is working, the airflow can only flow through the channel space, and the multiple sets of stripping wheel shafts almost occupy the stripping area. The vast majority (accounting for about 70%) of the effective cross-section of the passage cavity, just imagine that the exhaust fan can't all extract the leaf stripping shaft out? Then the sugarcane leaves pouring into the channel are blocked by the stripping impeller to form a dead zone, and they cannot be discharged quickly. More sugarcane leaves come in and less out, and finally the channel is blocked, which seriously affects the normal progress of sugarcane harvesting.

This is also one of the reasons why sugarcane harvesters are often prone to irreparable damage to internal mechanisms
