DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll bale hay control device for drying hay that has not yet been dried in a roll bale (hereinafter simply referred to as a roll bale) to produce hay. The present invention relates to a hay adjustment device for a roll bale, which can produce high-quality hay at low cost without being influenced by the hay.

[0002]

BACKGROUND OF THE INVENTION Moisture of grass immediately after cutting is 75 to 8%.
It is about 0% and must be dried to a moisture content of about 15 to 20% in order to make hay suitable for storage.
Therefore, the cut grass is usually dried in the field by the sun to adjust the hay.

However, when adjusting hay in the sun,
Although three to five days of clear weather are required, in Japan, the season of pasture cutting coincides with the rainy season, and it is difficult to produce high-quality hay constantly and economically. In other words, rainfall during hay adjustment has resulted in reduced quality and yield, leading to significant losses in livestock management.

[0004] Therefore, a method (artificial drying method) of drying the cut grass with a thermal blower dryer using light oil or heavy oil as a fuel is performed. In this method, although high-quality hay is obtained, Not only is there a problem that hay becomes expensive due to high fuel costs, etc., but the smell of fuel is soaked, the taste is poor, and there is a tendency that eating is difficult.

Further, a drying method using solar heat has been proposed. In the drying using solar heat, hay is adjusted by heating air using solar heat, and sucking and ventilating the heated air through the stacked grass.

[0006] This method solves the above-mentioned conventional problems and can produce high-quality hay at a low cost without being affected by the weather. However, this method is suitable for drying conventional grass-packed grass, so-called compact bale, but when it is recently used for drying roll-bale type grass, a gap between the roll bale is generated. Therefore, the drying efficiency is poor, and there has been a demand for the development of a hay unit for roll bale.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide a hay adjusting device for a roll bale which can solve the above-mentioned conventional problems and can produce high-quality hay at a low cost regardless of the weather. It is intended for.

[0008]

That is, the present invention provides a roll comprising a plurality of roll bale set tables installed in a greenhouse, a suction blower, and a duct connecting each roll bale set table to the suction blower. A bale hay adjustment device is provided.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a hay adjusting device according to the present invention will be described with reference to the drawings. FIG. 1 is a front view showing one embodiment of the hay adjusting device of the present invention, FIG. 2 is a plan view inside a greenhouse in one embodiment of the hay adjusting device of the present invention, and FIG. 3 is the hay adjusting device of the present invention. It is a side view of a suction blower and a roll bale set stand in one mode of an apparatus.

The hay adjusting device of the present invention comprises a plurality of roll bale set tables 2 installed in a greenhouse 1, a suction blower 3, and a duct 4 connecting each roll bale set table to the suction blower. . Here, the number of roll bale set tables 2 to be installed may be plural, and there is no particular limitation. The figure shows a case where a total of 10 roll bale set tables are installed. This roll bale set table 2
Is a pre-dried roll bale (approximately 45
(Approximately 0-600 kg), steel is usually used in consideration of strength, but the material is not limited to this as long as it has sufficient strength.

The roll bale set table 2 generally has a planar shape (shape shown as a plan view) according to the shape (cylindrical shape) of the undried roll bale placed thereon, as shown in FIG. The shape is circular as shown, but may be square if it does not hinder the suction of warm air. The cross-sectional shape of the roll bale set table 2 is usually in a mortar shape as shown in FIG. 1, and hot air is uniformly applied to the most depressed portion in the center of each roll bale. A warm air adjusting valve 5 is provided so that the air can be passed.

The hay adjusting device of the present invention comprises a plurality of roll bale set tables 2 as described above, a suction blower 3, and a duct 4 connecting each roll bale set table 2 and the suction blower 3. That is, each roll bale set table 2 is connected to the suction blower 3 by the duct 4.

The duct 4 has only to have an inside diameter sufficient to discharge hot air containing water to the outside of the greenhouse 1, and there is no particular limitation on the size and material. The duct 4 only needs to connect each roll bale set table 2 and the suction blower 3 as shown in FIG. 2, and directly connects each roll bale set table 2 and the suction blower 3 respectively. No need to be.

A commercially available suction blower 3 can be used. The suction blower 3 is installed on a boundary between the inside and outside of the greenhouse 1 so that warm air containing moisture can be discharged to the outside of the greenhouse 1.

The hay adjusting device of the present invention has the above-mentioned structure, but if necessary, as shown in FIG.
In order to maintain the temperature in the greenhouse 1, a hot air blower 6 for auxiliary heating may be installed.

A method of adjusting the hay by drying the undried roll bale using the hay adjusting device of the present invention as described above will be described.

First, prior to using the hay adjusting device of the present invention, the grass is preliminarily dried in the field until the water content becomes about 25 to 40% by weight. Immediately after cutting, the grass has a water content of about 75 to 80% by weight.
By drying in the sun in the field, it is possible to easily dry the water content to about 25 to 40% by weight in 2 to 3 days.

However, it takes two to three days to dry the hay to a moisture content of 15 to 20% by weight, which is then exposed to rain, which leads to a decrease in quality and a decrease in sales. There are many times that they incur significant losses.
According to the hay adjusting device of the present invention, the water content is 2 in the field.
The grass which has been pre-dried to about 5 to 40% by weight is packed in a roll bale by a roll baler, and the obtained roll bale A is economically reduced to 15 to 20% by weight suitable for storage in the greenhouse 1. Can be dried.

The grass (roll bale A: about 450 to 600 kg) preliminarily dried as described above is carried into the greenhouse 1 using a carry-in machine or the like, and placed on the roll bale set table 2. Next, preferably, the periphery of the roll bale A is covered with a sheet 7 (usually a vinyl sheet). Thereby, warm air can be efficiently sucked from the upper part of the roll bale A, and drying can be performed uniformly and efficiently.

Further, in order to perform drying uniformly, the amount of warm air is adjusted by the warm air adjusting valve 5 so that the amount of warm air passing through each roll bale becomes uniform. When the suction blower 3 is operated in this state, the warm air (heated by sunlight) in the greenhouse 1 passes through each roll bale A from the upper part of each roll bale A, and is dried to obtain water. The hot air containing the water passes through the hot air regulating valve 5 and the duct 4,
It reaches the suction blower 3 and is discharged out of the greenhouse 1 from there.

Thus, the roll bale set table 2
Each roll veil A placed above can be economically dried to a moisture content of 20% by weight or less, preferably 15% by weight or less. That is, desired hay adjustment can be performed. After the drying is completed, it may be carried out using a carry-out machine or the like.

[0022]

Next, the present invention will be described with reference to examples. Example 1 Roll bale A having a water content of 37% by weight was operated for 78 hours at the Iwate Ranch of the Livestock Improvement Center of the Ministry of Agriculture, Forestry and Fisheries using the hay adjusting device of the present invention shown in FIGS. Dried to less than% by weight. In this embodiment, a suction blower 3 having a blowing air volume of 340 m ³ / M was used. Further, as the roll bale set table 2 and the duct 4 connecting the roll bale set table 2 and the suction blower 3, an iron plate having a thickness of 1.6 m / m was used. Further, as the auxiliary heating warm air blower 6, one having a heat output of 20,000 kcal / H was used. The size of the hay adjusting device of the present invention shown in FIGS. 1 to 3 used in the present embodiment is such that the diameter of the roll bale set table 2 is 1.6 m and the warm air provided on the roll bale set table 2 The diameter of the suction port 8 at a position where the regulating valve 5 is located is 0.3 m, the width of the suction blower 3 is 1.1 m, the height is 1.2 m, each roll bale set table 2 and the suction blower are provided. The height and the width of the duct 4 connecting to the duct 3 were 0.5 m, respectively.

Table 1 shows the weight and dewatering amount of the roll bale A before and after the operation for 78 hours by the hay adjusting apparatus of the present invention shown in FIGS. As shown in Table 1, ten roll bales having an average moisture content of 37% by weight were dried for 78 hours, and as a result, hay was adjusted to an average moisture content of 12% by weight. The grass on each roll bale set table 2 could be adjusted to almost uniform hay.

FIG. 4 shows the change over time in the temperature inside the greenhouse 1 and the outside air temperature. The average temperature in the greenhouse 1 from the start to the end of the operation was 33.3 ° C. FIG. 5 shows changes over time in humidity on the roll bale A before ventilation (suction) and humidity at the outlet of the suction blower 3 after ventilation (suction). Further, FIG. 6 shows the change over time in the water content of grass (roll veil).

[0025]

[Table 1]

Example 2 Next, the utility costs of the hay adjusting device of the present invention shown in FIGS. 1 to 3 used in Example 1 and a conventional thermal drying device were compared. The results are shown in Table 2. According to Table 2, the utility cost of the hay adjustment device of the present invention is less than one-third of the utility cost of the conventional thermal drying device, which means that it is economically excellent.

[0027]

[Table 2]

Example 3 Table 4 shows the results of comparison of the nutritional value between the hay adjusting device of the present invention shown in FIGS. According to Table 4, it can be seen that the hay that has been adjusted in moisture by the hay adjusting device of the present invention has a higher nutritional value than sun-dried since the rate of leaves falling off in the field is small. In particular, in the case of sun drying, it can be seen that there is an effect of the hay adjusting device of the present invention on alfalfa hay, in which many leaves fall off.

[0029]

[Table 3]

[0030]

The hay adjusting device of the present invention has the following advantages. (A) Hay production, which tends to be influenced by the weather, can be produced stably and of high quality.

(A) The cost is lower than that of a conventional thermal dryer. That is, the utility cost is one third or less as compared with the conventional thermal dryer.

(C) It has a higher nutritional value than hay prepared by sun drying. Hay grass whose moisture has been adjusted by the hay adjusting device of the present invention has a higher nutritional value than sun-dried since the rate of leaf shedding in the field is small. Particularly in the case of sun drying, alfalfa hay, which has many leaves falling off, is effective with the hay adjusting device of the present invention.

(D) Since hay such as light oil is not soaked in the grass, it is possible to produce hay having high taste of livestock because it is dried by using solar heat. That is, the hay adjusted by the conventional thermal dryer using light oil or heavy oil as fuel,
The smell of the fuel is soaked, especially the palatability immediately after the end of drying is poor, and there is a tendency for foraging to occur, but the hay produced by the hay adjustment device of the present invention has an increased temperature in the greenhouse. Due to the use of warm air, the hay does not have a smell, has a peculiar scent, and has the same palatability as sun-dried one.

(E) Drying can be performed with the roll veil as it is, saving labor.
