Abstract

PROBLEM TO BE SOLVED: To prevent a livestock farm from being made muddy by burying a drain-board (or drain-boards) made of thin wooden boards on the ground surface without paving. SOLUTION: (1) The livestock farm is prevented from being made muddy by burying the drain-board 1 made of thin wooden boards 2 by bringing the long side of the cross section of the board to be vertical to prevent kneading and splashing of soil caused by hoofs of the livestock, penetrate water such as rain water into the underground and prevent the soil to be made muddy. (2) The thin wooden boards 2 used here have cross sections insufficient to bear the lord of the livestock by themselves, but they are made to have sufficient strengths by forming a composite material together with a geologic material 5 filled in spaces formed by spacers 3 of the drain board 1. The spaces of the drain board 1 are moderately arranged so as to place the hoof of the live stock on 2 to 3 thin boards. Thus, the material volume (quantity) of wood used for unit area is reduced and softness of the soil buried with the drain-board 1 is not spoiled.

Detailed Description of the Invention

TECHNICAL FIELD The present invention relates to a livestock raising place,
The present invention relates to a method for preventing mudification in a livestock raising place, which is capable of preventing mudification by burying a sludge made of a thin wooden plate on the ground surface without paving.

[0002]

2. Description of the Related Art In livestock farming, it is common practice to raise livestock outdoors in order to exercise the livestock or feed the livestock. If paving with concrete or asphalt is not carried out at the feeding place, the soil will become mud due to the soil hopping due to the hoofs of livestock and the clogging of the soil due to the mixing of feces.

As a result, there are the following adverse effects. ． During and after rainfall, the degree of mudification will be particularly large, making it impossible to use the breeding area. ． Due to mudification, the limbs of livestock are buried in the soil, making them unable to move normally. ． Livestock gets dirty due to the adhesion of mud. ． Increasing incidence of hoof disease because the hoof is constantly moist.

For this reason, conventionally, in order to prevent mud formation, a method of paving with concrete or asphalt, or a method of hardening soil by using a soil hardening agent has been used.

The applicant (former Ministry of Agriculture, Forestry and Fisheries Hokkaido Agricultural Experiment Station) is a Japanese Patent Publication No. 7-40845 as a method for preventing mud formation other than the method of paving with concrete or asphalt, or hardening the soil using a soil hardening agent. In the issue, "A net material obtained by polymerizing expanded metal on the underside of a plastic net on the ground surface is spread with iron pins so that it will not be buried in the soil, preventing the soil from repelling due to the hoofs of livestock and Water such as urine of animals and livestock is allowed to penetrate underground to prevent soil from becoming mud. ”

[0006]

When the breeding place is paved with concrete or asphalt as in the former case,
Alternatively, when soil is hardened using a soil hardening agent, the surface of the livestock farm becomes hard and slippery. Further, the hard surface of the ground adversely affects the limbs of the livestock, and the slipperiness of the ground causes accidents such as the livestock falling and being injured. Further, when paving with concrete or asphalt or solidifying with a soil hardening agent, evaporation of water from the ground surface is suppressed, so that the ground surface temperature rises in the summer and reflection becomes stronger. In addition, using concrete, asphalt, or soil hardening agents requires a large amount of cost, and when it becomes necessary to move livestock farms, it is necessary to newly construct them at the moved sites. Furthermore, in order to restore the place where the pavement and the soil were hardened by the soil hardening agent to the original state, it was necessary to perform the crushing and removing work using a heavy machine.

When the net material obtained by polymerizing expanded metal on the lower side of the plastic net on the ground surface is spread with iron pins so as not to be buried in the soil as in the latter case, the plastic is placed on the uppermost part. Since the net is used, when removing the feces on the net material by using the front loader or tractor, if the steel dump plate or bucket is used, the plastic net will be easily damaged,
It was necessary to use a special rubber scraper such as that used for tires. Further, since expanded metal made of metal is used, there is a problem that the cost becomes high.

On the basis of the above circumstances, the present invention can prevent mudification only by burying a duckboard made of a thin wooden plate on the ground surface without paving the place for raising livestock. It is an object of the present invention to provide a method for preventing mudification of a livestock raising place, which makes it possible to avoid such adverse effects easily.

[0009]

In order to achieve the above object, the present invention provides: It is a method of preventing mudification by livestock in a livestock farm that is not paved, and by embedding a wood thin plate sludge created with the long side of the mouth opening vertical to the ground surface, It is characterized by preventing the soil from repelling due to hoofs and allowing water such as rainwater to penetrate underground to prevent soil from becoming mud.

B. The thin wood plate used does not have a cross section that can withstand the load of livestock by itself, and it is made of a soil material and a composite material filled in the gaps of the soup to have sufficient strength. The gap is set just enough so that the hoofs of livestock can be placed on 2 or 3 thin plates, the volume of wood used per unit area can be reduced, and the soil at the place where the slats are buried can be softened. The feature is that it does not spoil the quality.

[0011]

According to the method for preventing mud mudling in a livestock raising place of the present invention by the above-mentioned means, the buried wood thin plate saw disperses the load due to the hoofs of the livestock, and the wood thin plate soot gap is filled. Since the complex of the soil material is not destroyed by the load of the hoofs of livestock, the soil hopping by the hoofs of livestock is eliminated, the water such as rainwater penetrates underground, and the ground surface is kept dry. It is prevented from becoming mud. Moreover, the removal of the thin wooden plate soot can be easily performed and can be moved. Furthermore, even if the steel excavation plate or bucket of the front loader or tractor is used as it is to remove feces, the slats will not be broken. Furthermore, the sludge not only bears the load of livestock, but also the load of work machines such as front loaders and tractors.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

First, the following points were taken into consideration when implementing the method for preventing mud formation of the present invention. 1) In order to retain the softness of the soil in the livestock farming area to a certain extent, use materials such as concrete and metal as much as possible, and use wood as the main material. 2) Even if this mud prevention method is implemented, the method of solidifying the soil should be taken so that livestock does not become slippery. 3) By using a material having a drape-like structure, evaporation of water from the ground surface is not suppressed, and it is possible to suppress an increase in ground surface temperature even in the summer.

4) By using a material mainly made of wood which is distributed in a single step by a simple processing method, paving with concrete or asphalt, solidification with a soil hardening agent, or expanded metal under the plastic net. To enable low-cost construction compared to a net material obtained by polymerizing. 5) When it is necessary to move to a livestock raising place, it is possible to move wooden thin plate saws so that it is not necessary to purchase new materials. In addition, it should be possible to restore the construction site to the state before the construction without crushing and removing construction using heavy equipment.

6) In order to protect the ground surface from soil hopping due to livestock hoofs, the load of livestock hoofs is dispersed and transmitted to the ground. 7) The unit to be used for this purpose is to make the cross section of the wood used to make the sludge as small as possible and to be able to withstand the load of livestock by being combined with the soil material filled in the gaps of the sludge. To reduce the volume of wood used per area.

From the above points, in the method of the present invention, as shown in FIG. 1, a thin wood plate (plate material) 2 is used as a main material for producing the sludge 1 for dispersing the load due to the hoofs of livestock. did. Moreover, wood or a pipe was adopted as the spacer 3 used to set the gap of the sludge 1 so that the hoofs of livestock could be placed on the two or three thin plates 2 without excess or deficiency. In order to alternately arrange the plate material 2 and the spacer 3 which are the main materials of the sludge 1, holes were made in both the plate material 2 and the spacer 3 and fixed by the through bolts and nuts 4.

The wood thin plate 2 used when the long side of the cross section is vertical is very strong against a vertical load. However, if the load direction is slightly deviated from the vertical direction and the thin plate 2 is twisted, the strength becomes extremely small. Therefore, by embedding the sludge 1 on the ground surface, the space between the sludge 1 is filled with the soil material 5. By doing so, even if the load deviates from the vertical direction, the soil material 5 with which the gap is filled does not twist the thin wooden plate 2 and can maintain a large strength. Further, by setting the gap between the slats 1 so that the hoofs of livestock are placed on the three or three thin plates 2, the soil material 5 does not undergo remixing by the hoofs, so that mud does not occur.

By making holes in both the main material 2 and the spacer 3 of the sludge 1 and fixing them with through bolts and nuts 4, the sludge 1 is prepared in advance. Excavate the surface of the ground where the method is to be carried out by the height of the sludge 1,
The soil material 5 such as soil or coarse-grained volcanic ash excavated after placing the drainboard 1 at that location is filled in the gap of the drainboard 1. It is also possible to place the sludge 1 without excavating the ground surface and cover it with the soil material 5 such as coarse-grained volcanic ash to the height of the sludge 1.

In this example, the method was carried out on the front side of a water tank for drinking cows (adult cattle) having a width of about 2 m and a depth of about 1 m. As the main material 2 of the sawdust 1, a wood thin plate 2 having a cross section of 12 mm (D) × 90 mm (H) and a length of 3.6 m was used. The main material 2 of the drainboard 1 was provided with holes for through bolts / nuts 4 at three locations, center and both ends. The spacer 3 has a cross section of 45 mm
A piece of wood (S) × 90 mm (H) and a length of 100 mm was used. A hole for a through bolt / nut 4 was made in the spacer 3 at the center of a 90 × 100 mm surface. Since the length and width of a hoof of an adult cow is more than 120 mm, the hoof of a cow is always placed on 2 to 3 main materials 2 of the saw by setting the gap between the slats 1 to 45 mm. The through bolt / nut 4 used had a diameter of 9 mm and a length of 1 m. Spacers 3 are alternately arranged at the three locations on the center and both ends of 18 sheets of the main material 2 of the sludge and fixed by through bolts and nuts 4,
A muffler board 1 having a length of m and a length of 3.6 m was produced. Eight identical slates 1 were prepared and placed in front of the above water tank so as to have a width of 8 m and a depth of 3.6 m. At the time of installation, the ground surface of the location was excavated by about 9 cm, and after placing 8 pieces of the sawdust 1, the gap between the sawdust 1 was filled with the coarse-grained volcanic ash 5.

The aquarium weighs about 60 and is left alone.
About 40 cows of 0 kg visited for drinking for about 8 months. At the place where this method was implemented, the load from the hoofs of livestock was dispersed by the sludge material and the soil was not remixed, so no mud was generated. In addition, the slates were neither damaged nor buried in the soil. On the other hand, the occurrence of mud formation was observed, such as pooling of water outside the place where this method was implemented.

[0021] Fig. 2 shows the mountain-type hardness of the ground surface at the place where the method is carried out and the place outside the place where the method is carried out in the spring when the mudification is generally remarkable at the outdoor feeding place. Shows the amount of precipitation by half of the season. For the Yamanaka hardness of the ground surface, the average value of 20 measurement points is shown. The Yamanaka hardness on the ground surface always shows a large value at the place where this method is applied, and it can be seen from the figure that the Yamanaka hardness tends to recover within a short period of time even if there is rainfall at the place where this method is applied.

That is, in a place where this method was not carried out, the soil was softened by the hoofs of livestock, so that the soil was softened and mud was generated, and the Yamanaka hardness of the ground surface was lowered. Conceivable. On the other hand, at the location where this method was implemented, mud was not generated because the soil was not remixed by the hoofs of livestock, and the mountain-type hardness of the ground surface was maintained at a large level and temporarily decreased after rainfall. However, it is presumed that it recovered in a short period of time.

As is clear from the above experimental results, the method for preventing mud formation according to the present invention has proved to be sufficiently practical.
Moreover, even if the steel excavation plate or bucket of the front loader or tractor is used as it is in order to remove the feces on the sludge 1, the sludge 1 will not be broken, and the load of the front loader or the tractor can be withstood. .

[0024]

As described above, according to the method for preventing mud mudling in a livestock raising place of the present invention, the slats of a thin wooden plate made so that the long side of the cross section of the mouth is vertical are embedded in the ground surface. Prevents the soil from bouncing due to the hoofs of livestock, permeates water such as rainwater into the ground, and prevents the soil from becoming mud, and the thin wood plate used by itself withstands the load of livestock. The cross section is not so large, and it is made of a composite material with the soil material that fills the gaps of the soot, so that it has sufficient strength. Since the amount of wood used per unit area is reduced and the softness of the soil at the location where this method is implemented is not impaired,
Compared to the method of paving with concrete or asphalt, the method of solidifying soil with a soil hardening agent, or the method of using expanded metal made of metal, it is possible to prevent mud in livestock farms more easily and at a lower cost. .

Further, when it is necessary to move the livestock raising place, the buried sludge is dug up and moved to obtain the same mud protection effect at the new livestock raising place. In addition, the outdoor breeding area can be used at all times, and the livestock can be exercised normally because the limbs of the livestock are not buried in the soil due to mudification. Therefore, the occurrence of hoof disease is suppressed. Furthermore, the drainboard can not only bear the load of livestock, but also the load of work machines such as front loaders and tractors.
