Description

Cutting fermentation device for preparing corn silage and preparation method thereof

Technical Field

The invention relates to the technical field of agricultural equipment, in particular to the technical field of silage, and specifically relates to a cutting fermentation device for preparing corn silage and a preparation method thereof.

Background

As a big corn planting country, the annual output of corn straws is increased year by year in China, and important resource guarantee is provided for the forage utilization of the straws due to the advantages of high output and low price. However, the comprehensive utilization rate of the straws is low, the popularization effect is poor, and the rationalization, the economy and the environmental protection of the utilization of the crop straws are severely restricted. So far, crop straws are still incinerated in many areas, so that straw resources are wasted, the environment is polluted, and the social benefit is seriously influenced. The development of animal husbandry, especially animal husbandry, combined with the advantages of saving food and improving the breeding productivity of straw feeding, has become an indispensable part of animal husbandry. However, direct feeding of crop straws has certain disadvantages, such as low palatability, loss of nutrients, easy mildew after long-term storage, and the like. At present, the method of manufacturing the silage or yellow silage is generally adopted, particularly the silage has the characteristics of good palatability, easy digestion, rich nutrition, convenient preparation and durable storage, is a storage method (about 83 percent of nutrition can be stored) with minimum loss of nutrient substances in the preparation of various coarse feeds, and can solve the problem of insufficient supply of the silage in winter. Because the silage has high manufacturing requirement and long period, the requirements on the silage are stricter and stricter. The silage harvest mainly comprises traditional manual harvest, semi-mechanical harvest and mechanical harvest. When the silage maize straw crops are harvested by using a traditional manual harvesting mode, the silage maize straw crops are usually harvested within the optimal harvesting period of more than ten days, a large amount of labor is needed, and the labor intensity of farmers is high; semi-mechanized harvesting operation is carried out, manual harvesting is needed, then mechanical crushing is carried out, and finally fermentation and storage are carried out, so that the labor intensity is low; the operation of mechanical harvest, silage harvester directly reaps in the field, breaks, send the crushed straw to the designated place to ferment, the operation is labour saving and time saving, because the characteristics of the domestic planting industry are not large-scale farm planting, the semi-mechanized harvest is the implementation mode most conforming to the vast ordinary agricultural workers, but at present, most of the domestic equipment is fixed model, basically, the personnel can only transport the straw to the site station with equipment, then send the straw into the equipment to operate and use, and then send the processed straw to the cellar storage of the user, thus the operation reduces the purchase and transportation of the equipment, but for the users far away in some regions, the transportation cost for transporting a large amount of straw and silage bags is higher, the convenience of the use is limited, especially, the cylindrical bundling mode is adopted for packaging in most regions at present, the cylindrical occupied space is larger and exists in the gap, it is difficult to use. After the existing equipment is fixed, the specific internal spacing and other parameters of the existing equipment are often difficult to adjust, the requirements for manufacturing silage for different kinds of livestock are difficult to realize, for example, cattle and sheep of different kinds have different tastes of silage, but the existing equipment is difficult to realize related customized adjustment, the silage is unfavorable for improving the effect of promoting growth of silage, silage raw materials sent by different people are different, if the silage needs semi-dry silage, additives are needed for some people, the machine is very easy to use disorderly, different pollutants are reserved, and the influence is caused on the feeding of different livestock.

let both sides in the section of stepping down (12022) be equipped with the spout of stepping down (120222), both sides at the spout of stepping down (120222) are equipped with a sliding block as the section head of stepping down (120221), let section head (120221) be equipped with one and keep off cloth (120223) to the inner of the section of stepping down (12022), keep off cloth (120223) and stretch out and cover whole section of stepping down (12022) when the section head of stepping down (120221) moves the outer end of the section of stepping down (12022), let whole section of stepping down (12022) empty in order to avoid influencing spray pipe (1204) when letting section head (120221) move the inner of the section of stepping down (12022).

7. A method for manufacturing corn silage using the cutting and fermenting apparatus for manufacturing corn silage according to any one of claims 1 to 6, comprising the steps of:

the harvested corn straws are cleaned and dried in the sun, no soil is ensured, and the corn straws are laid on the feeding mechanism (2) and fed into the feeding mechanism (3) under the pressure of the lower feeding conveying belt (201) and the upper feeding conveying belt (202); and extruded and cut into strips through a feeding mechanism (3); then the mixture is cut into particles by a cutting mechanism (4); the straw is conveyed into a material pressing mechanism (6) through a material pressing conveying mechanism (5) for material pressing, so that part of the straw sections which are not treated in the previous step further form a particle structure; after entering the vibrating sieve plate (801), the materials with the granularity not meeting the requirement are sent back to the material pressing and conveying mechanism (5) again, and the materials which meet the requirement are sent to the bundling mechanism (11) by the bundling and conveying mechanism (9); the bundling mechanism (11) firstly moves the front plate (1105) to the bottom downwards, at the moment, the hydraulic lifting rod (1101) drives the bundling box body (1102) to enable the bin bottom plate (11034) of the bundling bin (1103) to be butted to the outlet direction of the bundling conveying mechanism (9), and as the bundling conveying mechanism (9) has a certain speed, straw particles in the bundling box body can be conveyed to a position close to the middle of the bin bottom plate, and the liquid spraying shower head (1205) sprays liquid on the straw particles in the process; when the bin bottom plate (11034) is stacked to a certain height, the operation of all the mechanisms is stopped, the downward pressing hydraulic cylinder (1111) is started, the bottom pressing plate (1110) is enabled to be pressed flat and tightly press the straw particles, then the hydraulic lifting rod (1101) is moved downwards to drive the whole bundling mechanism (11) to move downwards, the outlet direction of the bundling conveying mechanism (9) corresponds to a new position, so that the straw particles in a new round are stacked, the position of the front plate (1105) is moved upwards synchronously, the pressing operation is repeated until the sufficient silage blocks are tightly pressed in the whole bundling bin (1103), and then the operation of all the mechanisms is stopped; open back case lid (101), drive and beat bundle storehouse (1103) and shift out and beat bundle box (1102), after storehouse bottom plate (11034) lost the spacing of beating bundle box (1102), whole silage piece fell down in opening corresponding bag body (1401), then storehouse bottom plate (11034) playback, close back case lid (101) and let beat bundle storehouse (1103) playback, resume the operation of aforementioned all mechanisms this moment, move out fermentation bag (14), and use evacuating device (15) that set up in machine box (1) side to fermentation bag (14) evacuation, the completion is to the storage of silage piece.
