Baler safety alarm device

Abstract

The invention relates to a safety alarming device of a bundling machine.The safety alarming device comprises a driving power supply, a first alarming bell, a second alarming bell, a third alarming bell, a fourth alarming bell, a power switch, a motor, an electromagnetic relay and a detection device.The detection device comprises an upper detection roller, a lower detection roller and a tension detection device body.The safety alarming device of the bundling machine is simple in structure, flexible in response, fast in alarming action and high in precision; the upper detection roller and the lower detection roller are used for detecting the squeezing force of a grass bundle, pressure is transmitted with a hydraulic technology, the tension detection device body is used for detecting the tension generated in the spreading process of a screen and is sensitive in detection and high in detection precision; when the bundling machine has the abnormity that the grass bundling pressure is too large or the wound screen enters a bundling forming chamber without working or rolling in occurs when the bundling machine stops, the safety alarming device of the bundling machine can automatically give out an alarm without manual intervention.

Description

technical field [0001] The invention relates to a safety alarm device for a baler, which belongs to the technical field of agricultural machinery. Background technique [0002] Crop straw is a derivative proportional to the output of agricultural products in agricultural production. In recent years, straw incineration, waste and the resulting environmental pollution, soil mineralization, and waste of resources have become serious in China. In the process of comprehensive utilization of straw, collection, storage and transportation have become the primary problems that need to be solved urgently. However, straw collection is a relatively cumbersome operation. Due to the low density and dispersion of straw, it is difficult to collect, and the cost of storage and transportation is high. These have become problems in the development of large-scale industrialization and commercialization of straw. According to actual needs, storing or transporting straw into high-density bales ...

AI Technical Summary

Problems solved by technology

During the daily operation of the baler, due to improper use or maintenance of the equipment, there will be excessive pressure on the bale, the winding net on the net release device will not work when it is sent into the baling room, and the baler will stop and get involved. When the baler is baling, the straw is squeezed into bales inside the baling chamber. When the density of the bale exceeds the set value, that is, the internal pressure of the bale exceeds the set value or the rotating roller on the baling chamber The extrusion force of the bale exceeds the set value, the internal pressure of the bale is too large or the extrusion force of the rotary pressure roller is too large, which will not only easily lead to deformation and damage of the rotary pressure roller, but also cause the friction between the bale and the rotary pressure roller If the force increases sharply, it will easily cause the movable bin to fail to open, which will affect the discharge of the bale; and the friction between the bale and the rotating pressure roller will increase sharply, which will also easily cause the resistance of the entangled net to advance in the bale chamber, making it impossible to carry out the bale discharge. Netting

When the above-mentioned abnormality occurs in the existing baler, there is no relevant alarm device, and the above-mentioned anomaly cannot be detected and solved in time, which not only affects the normal operation of the baler, but also causes damage and scrapping of the baler
