Abstract

The invention relates to a straw smashing and spraying combined operation machine comprising a tractor truck, a straw smashing machine and a decomposition agent spraying apparatus, wherein the straw smashing machine is provided with a suspension bracket linked with the tractor truck, the straw smashing machine comprises a cutter shaft, a shell and a land wheel, the cutter shaft is provided with a blade and is assembled in the shell, the land wheel is arranged behind a shell discharging port, the decomposition agent spraying device comprises a liquid storage tank, a water pump set and spray nozzles, the liquid storage tank is provided with a liquid inlet and a liquid outlet, the liquid inlet of the water pump set is communicated with the liquid outlet of the liquid storage tank, and the liquid outlet of the water pump set is communicated with the spray nozzles. The spraying device is characterized in that the decomposition agent spraying apparatus is fixed on the shell through a fixing bracket, two groups of the spray nozzles are provided, one group of primary spray nozzles are arranged under the shell discharging port, and the other group of secondary spray nozzles are arranged behind the land wheel. The method comprises the following steps: assembling the device, loading the liquid medicine and spraying the liquid medicine. The method and the device have the beneficial effect of improving the straw decomposition efficiency by means of accelerating straw decomposition through secondary spraying of a biochemical preparation.

Description

Technical field [0001] The invention relates to the technical field of straw crushing, in particular to a spraying method and equipment of a straw decomposing agent. Background technique [0002] With the continuous development of modern agriculture, the straw chopping device attached to the combine harvester can organically combine crop harvesting and straw return, which reduces operating costs, is flexible and convenient, and is suitable for large-area farmland operations. It is the most promising straw return. One of the development directions of Tian. Many domestic enterprises are actively developing and producing. For example, they have produced straw shredding devices for Xinjiang 1-2 combine harvesters; in addition, taking the road of combining agronomy, biotechnology and agricultural machinery is also the only way for the development of straw-returning combined operations. The mechanization of straw returning to the field can change the physical properties of straw and p...

Problems solved by technology

[0003] At present, the spraying of decomposing agents in most rural areas of our country is done by manual sprayers. Due to the simple structure of the sprayers, most of them do not have a backflow device, so it is easy to cause excessive pressure in the sprayer medicine box and the leakage of the medicine liquid in the medicine box. The problems of dripping, dripping and leaking are very serious. In addition to manual operation, the labor intensity is high. The applicators often ignore safety issues, especially in hot summer, which can easily cause poisoning of applicators.
