Description

Technical Field

[0001] The invention relates to the technical field of silage additive spraying equipment, in particular to a variable mixing medicine spraying silage additive device under real-time detection results of near infrared spectrum. Background Art

[0002] Silage refers to the feed preservation technology of fresh green raw materials, such as silage corn, corn stalks and forage grass, under anaerobic conditions through microbial fermentation. Silage additives play an important role in animal husbandry and are an indispensable source of high-quality feed in modern animal husbandry. The spraying of silage additives is an important part of silage production and provides an important guarantee for the subsequent production of silage. Silage additives are divided into four categories: 1) Fermentation promoters: mainly promote the fermentation of lactic acid bacteria to achieve the purpose of fresh-keeping storage. 2) Fermentation inhibitors: mainly inhibit the activity of harmful microorganisms during silage fermentation, prevent raw materials from mildew and decay, and reduce the loss of nutrients. 3) Nutritional additives: used to supplement the nutrients in silage and improve the palatability of silage. 4) Other additives: enzyme preparations, enzyme preparations, various cell wall degrading enzymes, chemical additives, various acids, antibacterial agents, etc.; and according to the physical state, silage additives are basically divided into two categories: powder and liquid agents; and according to the method of using silage additives, silage additives are basically divided into two categories: silage additives diluted with water for spraying and additives mixed with corn flour for even mixing and spreading. The detection of the state of silage raw materials can provide an important basis for the spraying of silage additives. Spectral detection is an important means of non-destructive detection of silage raw materials, especially near-infrared spectroscopy non-destructive detection is widely used. In the research of agricultural production, ecological protection, straw into meat and grain into feed, the detection of silage raw materials and the spraying amount of silage additives are important indicator parameters. At present, there are few methods for spraying silage additives, and the common ones are manual spraying and ground machine spraying. Different spraying methods have their own advantages and disadvantages. There are limitations in the spraying process, which are affected by the area of ​​the spraying area and environmental factors. Among them, the manual spraying method is the traditional method of spraying silage additives. Manually carry portable sprayers to spray the silage raw materials. The capacity of the medicine box is small, and the spraying process is time-consuming and laborious, which is not conducive to long-term and continuous outdoor spraying. The ground machine spraying method is to set up a spraying machine next to the silage kiln. Every time a layer of silage is added in the silage kiln, the silage additive is sprayed once, but it cannot realize variable spraying of silage additives according to the relevant state of the silage raw materials.

[0003] The above methods often have many disadvantages: first, the manual spraying of silage additives cannot achieve high efficiency; second, the amount of additive spraying cannot be accurately variable and cannot be variable according to the detection of silage raw materials; third, the uniformity of silage additive spraying cannot be guaranteed.

[0004] Compared with the traditional silage additive spraying method, the near-infrared spectroscopy real-time detection results of variable mixing spraying silage additives have the advantages of precise variable spraying, good uniformity, and avoiding additive waste. Summary of the invention

[0009] The hardware components of the detection module mainly include: near-infrared spectrum sensor. When the near-infrared spectrum detection is used in the spectral region of 900nm to 1700nm, information such as silage raw materials is collected. The basic working principle of the module is: when the detection module is placed on the connection platform of the silage harvester throwing barrel to work, the near-infrared spectrum detection data corresponding to the silage raw materials is obtained and uploaded to the controller. The vehicle power supply uses the power cord to power the near-infrared spectrometer through the transformer module, and the near-infrared spectrometer is reliably installed on the controller using the data cable.

[0011] In order to make the spectrum detection module better realize its function and protect its internal structure from damage, a specific shell needs to be designed to protect the entire module. The shape of the shell is based on the original shape of the acquisition module and is designed to be square. First, it is convenient for processing and installation, and second, it is convenient for the installation of the detection module. When designing the shell, a fixed threaded hole is left on the bottom surface to facilitate the later installation on the silage harvester throwing barrel connection platform. The shell design material is carbon steel material, and it is painted.

[0012] The concentrated silage additive spraying operation is performed by the additive pump. The additive liquid is output from the additive box, passes through the filter, and the flow rate is adjusted by the electric regulating valve. The pressure sensor and the flow sensor monitor the pressure and flow rate. The additive liquid passes through the inlet pipe of the jet mixer. At the same time, the components of the water solvent pipeline do not work. The additive liquid reaches the right-angle elbow nozzle through the static pipeline mixer, the pressure sensor and the flow sensor in the mixing pipeline to complete the spraying operation of the concentrated silage additive.

[0013] The variable spraying operation of the silage additive is that the near-infrared spectrum detection module is installed on the connecting platform of the silage harvester throwing barrel, and the relevant parameters of the silage raw materials inside the silage harvester throwing barrel, such as the dry matter content of the silage raw materials, are detected. The data is transmitted to the controller, and the controller sends a command. The additive pump operates, and the additive liquid is output from the additive box, passes through the filter, and the flow is adjusted by the electric regulating valve. The pressure sensor and the flow sensor monitor the pressure and flow. The liquid passes through the inlet pipe of the jet mixer. At the same time, the water solvent pipeline also works, the water pump operates, and the water solvent is output from the water tank, passes through the filter, and reaches the main inlet of the T-shaped three-way pipe. The flow is adjusted by the electric regulating valve on the bypass. The pressure sensor and the flow sensor monitor the pressure and flow. The liquid passes through the water inlet of the jet mixer, and the additive liquid and the water solvent are evenly mixed by the jet mixer. The mixed liquid is further mixed by the static pipe mixer in the mixing pipeline, and reaches the right-angle elbow nozzle through the pressure sensor and the flow sensor to complete the variable concentration agent spraying operation.

[0014] When the mechanism is working, it is installed on the self-propelled silage harvester. The near-infrared spectrum detection module includes a near-infrared spectrometer set on the connection platform of the silage harvester throwing barrel, and the mechanism is fixed through the connection plate with bolts and nuts. When the system is working, the near-infrared spectrometer collects information and transmits the collected information to the controller. The controller sends a spraying signal, and then the additive pump and the water pump work at the same time. The additive and the water solvent are mixed through the mixing device, and the mixed agent reaches the nozzle to start the agent spraying.

[0015] The method for spraying the agent using the above-mentioned device for spraying silage additives by mixing the agent based on the real-time detection result variable is carried out according to the following steps:

[0016] The self-propelled silage harvester operates on a large field silage crop plot. The vehicle-mounted power supply is powered by a transformer module. The near-infrared spectrum detection module starts to detect parameters related to the silage raw materials, such as the dry matter content of the silage raw materials, and transmits the dry matter content data of the silage raw materials to the controller. The controller sends a signal to start the additive pump, and the flow rate is controlled by the opening of the electric regulating valve of the additive branch pipeline. The pressure and flow parameters of the additive branch pipeline are monitored by the additive branch pipeline pressure sensor and flow sensor. The additive enters the injection mixer inlet pipe, and the water pump is started at the same time. The flow rate is controlled by the opening of the electric regulating valve of the water solvent branch pipeline bypass. The pressure and flow parameters of the water solvent branch pipeline are monitored by the water solvent branch pipeline pressure sensor and flow sensor. The water solvent enters the water inlet of the jet mixer, and the additive and the water solvent are evenly mixed and enter the static pipeline mixer. The mixture enters the right-angle elbow nozzle through the pressure sensor and flow sensor of the mixing pipeline to spray the mixed agent, and the pressure and flow parameters of the mixing pipeline are monitored by the mixing pipeline pressure sensor and flow sensor.

[0017] The beneficial effects of the present invention are:

The spraying device can be installed on the existing self-propelled silage harvester throwing barrel to realize automatic variable spraying of silage additives.

[0019] (2) The silage raw material parameters detected by the near-infrared spectroscopy detection module are sent to the controller to control the operation of the additive sub-pipeline and the water solvent sub-pipeline, and the silage additives of different concentrations are mixed through the mixing pipeline to achieve variable concentration spraying of the silage additives.
