Description

Technical Field

[0001] The invention relates to the technical field of seedling raising plate equipment production, and in particular to a straw seedling raising plate production line. Background Art

[0002] Rice is the main crop in my country's grain production. The main rice producing area in the three northeastern provinces is Heilongjiang Province, which plays a pivotal role in national production. The rice planting area in Heilongjiang, Jilin and Liaoning provinces exceeds 81 million mu, of which Heilongjiang Province has a rice planting area of ​​about 60 million mu, making it an important commercial grain production base in my country. The dry seedling raising and sparse planting technology for rice seedlings, that is, transplanting after raising seedlings in greenhouses, is the key to high-quality and high-yield rice. However, dry seedling raising requires loose, fertile, permeable and nutrient-rich humus soil as the seedbed soil. With the extension of the rice planting period and the widespread use of herbicides, a large amount of high-quality arable land soil layers have been destroyed, and the high-quality soil layer of black soil has also decreased. It is becoming increasingly difficult to collect high-quality seedbed soil required for rice seedling raising. Straw is the residue of mature crops after harvesting seeds. More than half of the products of crop photosynthesis exist in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. However, due to the large scale of grain production and the large amount of straw in my country, except for a small amount of straw that is crushed and returned to the field, biomass power generation, livestock feeding, and composting, most of it is directly burned because of its low added value and is not reasonably utilized. Using straw to prepare seedling raising boards will be a trend of future development. It is a new type of production material that has just emerged and can be industrialized and replace traditional seedling raising in seedling bed soil. Conventional traditional nutrient soil seedling raising requires soil extraction, soil transportation, soil powder, soil screening, fertilizer mixing, acid mixing, and seedling strengthening agent mixing before it can be made into nutrient soil for seedling raising. Then the nutrient soil must be put into the seedling raising tray and the seedling bed soil must be smoothed. When using seedling raising boards for seedling raising, you only need to put the seedling raising board into the plastic tray for seedling raising. Compared with traditional nutrient soil seedling raising, it saves more than 50% of the seedling raising production process, is simple to operate, saves time and effort, and improves efficiency. The three-layer structure seedling raising board produced by this method not only has the characteristics of full nutrition, but also has the characteristics of not distinguishing between the front and back sides, which makes it more convenient to use. No fertilizer is applied during the entire process of the seedling raising period, which is a subversive innovation to the traditional seedling raising method. At present, the seedling raising boards that have been developed are all produced by the wet method. The seedling raising boards produced by the wet method use vacuum suction molding equipment. The equipment process method is to first crush the main materials such as plant straw and mix them with the auxiliary materials and add water to the slurry pool to make it into a muddy state. When the main template of the rotary drum vacuum suction molding machine rotates to a low position with the rotary drum, the surface of the template absorbs wet solid matter from the slurry pool. As the rotary drum rotates upward, it docks with the auxiliary template and squeezes out a large amount of water. The auxiliary template removes the blank and then enters the dryer for drying.The pulp pool of this method is difficult to preserve the various nutrients required for the seedling raising period in the seedling raising board, and the concentration of raw materials and auxiliary materials in the pulp pool is difficult to control, resulting in the seedling raising board produced by this method requiring at least one acid supplement and multiple fertilizer supplements during the seedling raising period, and the substances in the pulp pool need to be discharged within a certain period of time. In addition, the seedling raising board produced by the wet method has great limitations in terms of equipment and process methods because it adopts suction molding technology. It is necessary to solve the problems of not subjecting the straw to high-temperature and high-pressure softening treatment and inactivating the pathogens carried by the straw to improve the disease resistance of the seedlings, destroying the wax layer and lignin structure in the straw and grinding the straw into fibers to improve the fertilizer retention and water retention, and treating the straw fibers with and auxiliary materials to avoid the problem of seedling burn or weak seedlings during the seedling period due to inaccurate measurement, add straw fiber and various nutrients and additives into the seedling raising slab to make it have full nutritional characteristics without the need for fertilizer and acid supplementation, use the core and surface three-layer structure of the seedling raising slab material for more convenient use, lay the seedling raising slab into a large format to improve production efficiency, use the pad as a carrier due to the small characteristics of the straw fiber raw materials and various auxiliary materials required for seedling raising, and separate the seedling raising slab and the pad after hot pressing, cut the large-format seedling raising slab vertically and horizontally according to the standard seedling raising slab size required for rice seedling raising, and count the stacks according to the number required for packaging. Summary of the invention

[0003] The present invention aims at the characteristics of the traditional seedling bed soil seedling raising method that requires soil taking and the process is dirty and complicated, and also at the problem that the wet-processed seedling raising board has great limitations in equipment and process methods because it adopts suction mold forming technology. It is necessary to solve the problem of not subjecting the straw to high-temperature and high-pressure softening treatment and inactivating the pathogens carried by the straw to improve the disease resistance of the seedlings, destroying the wax layer and lignin structure in the straw and grinding the straw into fibers to improve the fertilizer retention and water retention, avoiding the problem of burning or weak seedlings during the seedling raising period due to inaccurate metering of straw fibers and auxiliary materials, and all the straw fibers and various nutrients and additives. The invention relates to a method for adding the straw to the rice seedling raising board to make it have full nutritional characteristics without the need for fertilizer and acid supplementation, a method for paving the rice seedling raising board material with a core-surface three-layer structure to make it more convenient to use, a method for paving the rice seedling raising board material into a large format to improve production efficiency, a method for separating the rice seedling raising board and the pad after hot pressing the pad because the straw fiber raw materials and various auxiliary materials required for rice seedling raising are small and the pad is used as a carrier, a method for cutting the large-format rice seedling raising board vertically and horizontally according to the standard rice seedling raising board size required for rice seedling raising, and a method for counting the stacked boards according to the number required for packaging.

[0072] Working principle:

[0073] The straw raw material is transmitted to the silo of the straw spiral-driven feeding horizontal steamer through the straw feeding conveyor device. The feeding screw of the straw forced feeding device forces the straw segments to be fed into the plunger spiral guide tube cavity. The purpose of using the spiral device to transport the straw is to avoid the phenomenon of straw bridging and clogging during the transportation process. The feeding plunger spiral propeller in the plunger spiral guide tube cavity continuously feeds the straw segments into the spiral-driven feeding horizontal steamer. The spiral-driven feeding horizontal steamer steams the straw raw material at high temperature and inactivates various pathogens carried by the straw. Then, the high-temperature steamed straw raw material is continuously transported to the straw fiber grinder for grinding. Grinding and kneading it into fiber can destroy the wax layer and lignin structure in the straw, make the straw fiber soft, and is more conducive to the fertilizer and water retention of the seedling raising board with straw as the main material during the seedling raising period, and can cultivate excellent seedlings. The straw fiber grinder grinds the raw material into fiber The material is sent to a dryer for drying, and the dried fibrous raw material is sent to a straw fiber and auxiliary material metering device for metering. The metered raw material and auxiliary material are sent to a mixer for stirring, and the evenly stirred raw material is transported to a three-layer mechanical paving machine for paving. The paved slab and pad are sent to a loader through a conveyor, and the loader sends them to a hot press for hot pressing. The hot press sends the hot-pressed seedling raising plate to a plate unloader, and the plate unloader then sends the formed seedling raising plate to a suction cup type seedling raising plate and pad separation and stacking device through a conveyor to separate the seedling raising plate from the pad, and the separated pad is returned to the front end of the paving machine by a return conveyor, and the separated seedling raising plate is transported to the seedling raising plate longitudinal and transverse cutting and counting stacking device for cutting, and after longitudinal and transverse cutting according to the product size required for seedling raising, the standard-sized seedling raising plate is sent to the longitudinal and transverse conveyors and the stacking counting machine and stacked according to the quantity required for packaging, thereby completing the assembly line production of seedling raising plates of the present invention.
