Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cow bed mat.

[0002]

2. Description of the Related Art Speaking of dairy cows, the image of loosely grazing on a large ranch comes to mind, but in a few cases, the country is small in Japan, and most dairy cows are housed in a barn. They are given a space for one animal and are bred in a situation where they can only stand, sit or recline. If you slide your legs during this standing, sitting or recumbent movement, you will end up with diseases such as arthritis and dislocation, and in the worst case, you will be dead. In addition, even if death does not occur, trauma is caused by these diseases, and as a result of not performing other actions while standing or lying down, there are many cases that lead to a decrease in milk production. There is. In a normal state, 50% of daily dairy cows stand up and sit down in 10 to 15 times, and in order to maintain such a state, dairy cows should be prevented from slipping or impacting. It is necessary to prevent it. For this reason, rubber mats are used to prevent dairy cows from slipping and impacting on the cow bed. As this rubber mat, there has been proposed a mat having a plurality of grooves formed on the surface thereof, as disclosed in JP-A-7-203792.

[0003]

However, the rubber mat disclosed in the above-mentioned Japanese Patent Laid-Open No. 7-203792 has a plurality of grooves formed on the surface thereof, but the grooves are simple straight lines in the front-rear direction. Only, no other device has been made. In addition, as described above, in a normal state, 50% of the day, the dairy cow stands up in 10 to 15 times, and sits down and reclines. In particular, it is a burden to stand up in a recumbent or recumbent state. Also, due to the structure of the barn,
In many cases, there is a lower step in the cow bed between the food storage area where the food is placed and the cow bed, and when a dairy cow eats food, the front leg often hits this step and is damaged. is doing. Therefore, the present invention has been made to solve these problems, and has a large effect of preventing slippage on the legs of a cow, and it is not a burden to stand up from a recumbent or recumbent state, and the front legs are stepped. It is intended to provide a cow bed mat capable of preventing the cow mat from hitting.

[0004]

As a result of observing the behavior of dairy cows, the inventor has found the following. Due to the weight distribution and skeleton structure of a dairy cow, when standing up from a recumbent position, when the weight is applied to the front leg and the rear leg stands up, the rear leg tends to slip outward. In addition, milk is produced in the body of a dairy cow when the dairy cow is in a recumbent state, and it is important that stress is not applied during this recumbent state. Therefore, when a cow bed mat is used, if the surface of the cow bed mat has a large unevenness, it causes pressure on the cow's body to cause congestion and cause stress.Therefore, a cow bed mat that the cow's body touches when lying down is used. It is desirable that the surface irregularities be as small as possible. In addition, the cow has an instinct to take a posture in which the head position can be raised to relieve stress when lying down. Therefore, the present invention has been made paying attention to these points, and in the surface area of the cow bed mat,
By providing a more effective slip control surface on the surface of the surrounding area that is not used for lying down, stress is not applied when lying down, while increasing the slip prevention effect, and the surface of the cow bed mat is stepped on the front legs. Incline so that the area is higher than the area where the rear legs are stepping on,
The aim is also to reduce the burden of standing up from a recumbent or recumbent state, and to make it easier for the cow to take a posture in which the head position can be raised. Further, in the present invention, when the dairy cow is standing up from a recumbent or recumbent state, a stronger force is applied to the front leg than the rear leg, or when sitting down from the standing posture, the knee of the front leg is more than the rear leg. Also considers that strong force is added.

The first cattle mat of the present invention has one cow

Embodiments of the present invention will now be described in detail with reference to the drawings. The cow bed mat described in the present embodiment is a mat to be used by being laid on a cow bed in a cowshed which is partitioned by an area necessary for one dairy cow to stand up, sit down or lie down. FIG. 1 is a plan view of a cow bed mat of the first embodiment, FIG. 2 is a sectional view taken along line I-I, FIG. 3 is a sectional view taken along line II-II, and FIG. 4 is a rear view thereof. This beef mat 1
Is a rectangular sheet with the longitudinal direction in the front-rear direction, and its size is 1800 mm (a in FIG. 1) and 1200 mm (b in FIG. 1) with the longitudinal direction as the vertical direction. It has the necessary space for standing, sitting or lying down. As shown in FIG. 2, the surface of the cow bed mat 1 is inclined in the front-rear direction so that its front end is higher than its rear end. That is, the surface of the cow bed mat is inclined so that the area where the front legs are stepped on is higher than the area where the rear legs are stepped on. Depending on the implementation situation, this slope seems to be favorable between 1.8% and 2.0%. In this embodiment, the thickness of the cow bed mat 1 is 70 mm at the front end (see FIG. 2).
C) and 40 mm at the rear end (d in FIG. 2). In addition, this cow bed mat 1 is composed of a front surface layer 2 and a back surface layer 3,
The back surface layer 3 is formed thicker than the front surface layer 2.
In this embodiment, the thickness of the surface layer 2 is 20 mm (e in FIG. 2). In this way, by constructing the cow bed mat 1 with the two layers of the front surface layer 2 and the back surface layer 3,
Two different properties of the front surface layer 2 and the back surface layer 3 can be provided. For example, the surface layer 2 should have sufficient strength to withstand stepping on the cow's legs,
The back surface layer 3 is provided with a property of softening the impact on the legs due to the stepping on the legs. In this case, since the back surface layer 3 is formed thicker than the front surface layer 2, the back surface layer 3
The property of can be fully exhibited. In the barn, the cow bed mat 1 is laid on the cow bed so that the front-back direction of the cow mat 1 is aligned with the front-back direction of the cow.

On the surface of the surface layer 2 of the above cow bed mat,
As shown in FIG. 1, a groove that is parallel to the front-back direction of the cow, that is, the longitudinal direction of the beef mat, is formed in order to form the slip-regulating surface that restricts the left and right sliding of the rear legs of the cow. Article 21 is juxtaposed. As shown in FIG. 3, the depth of the groove 21 is a sitting / side lying area 31 (indicated by a dotted line in FIG. 1) which is an area used for sitting or lying in the surface area of the beef mat 1. The inside area is different from the surrounding area (outside of the dotted line in FIG. 1). The depth of the groove 21a in the peripheral area is the same as that of the groove 21 in the sitting / side lying area 31.
It is formed deeper than the depth of b, and these depths are
The groove 21a in the peripheral area is 10 mm, and the groove 21b in the recumbent / recumbent area 31 is 5 mm.

The back surface layer 3 of the beef mat 1 is formed by mixing and pressing rubber chips of different sizes obtained by crushing used rubber tires into chips of 3 to 7 mm.
The hardness is about 40 to 60, but the cow bed mat 1 of the first embodiment has different hardness depending on the part. That is, the portion of the back surface layer corresponding to the portion of the front layer on which the both front legs step is made softer than the portion of the back surface layer corresponding to the portion of the surface layer on which the two rear legs step. Specifically, the hardness of the back surface layer portion corresponding to the front surface layer portion where both front legs are stepped is about 45, and the hardness of the back surface layer portion corresponding to the front surface layer portion where both the rear legs are contacted is 55.
It is about before and after. The hardness can be adjusted by combining rubber chips of different sizes and adjusting the applied pressure. Further, a hemispherical recess 22 having a diameter of 50 mm is provided on the surface of the back surface layer 3.

As described above, the above-mentioned cow bed mat 1 is provided with the linear grooves 21 parallel to the front-back direction of the dairy cow on its surface. This groove 21 is a peripheral area in which the depth of the groove 21b of the sitting / recumbent area 31 used for sitting or reclining is an area other than the recumbent / recumbent area 31 that is not used for recumbent or recumbent. Groove 21a
It is formed to be shallower than the depth of. Conversely, the depth of the groove 21a in the peripheral area is formed to be deeper than the depth of the groove 21b in the recumbent / recumbent area 31. Therefore, the groove 21b of the sitting and lying position 31
Due to the shallow depth of the dairy cow, it is possible to prevent pressure on the dairy cow's body, resulting in the congestion that causes stress. Further, as described above, due to the weight distribution of the dairy cow and the structure of the skeleton, when standing up from the recumbent position, when the weight is applied to the front legs and the rear legs stand up, the rear legs tend to slip outward. is there. Therefore, when this cow bed mat 1 is used for a cow bed, when the rear leg starts to slide when the dairy cow stands up from the sitting position, the sitting / side lying area 31
Since the shallow groove 21b is provided in the area, it has an anti-slip effect even in this area. However, when the rear leg reaches the peripheral area by slipping further, the depth of the groove 21a in the area is receded. -Since it is deeper than the recumbent area 31, it has a great anti-slip effect and can reliably prevent the rear leg from slipping. Therefore, it is possible to prevent the above-mentioned harmful effects on the dairy cow caused by the sliding of the hind legs. Further, since the groove 21 is provided on the mat surface, the groove 21
Since the dust collected in (1) can be removed along the groove 21, the surface of the cow bed mat 1 can be easily cleaned.

The cattle bed mat 1 has
The surface of the cow bed mat 1 is inclined so that its front end is higher than its rear end. That is, the surface of the cow bed mat is inclined so that the area where the front legs are stepped on is higher than the area where the rear legs are stepped on. Therefore, by using this cow bed mat 1, it is possible to reduce the load when the dairy cow stands up in the recumbent or recumbent state, and eliminates the stress when the dairy cow stands up in the recumbent or recumbent state. Can be made. In addition, it is possible to make it easier for the cow to take the posture that the cow has instinctively and can raise the head position when lying down, and the stress on the cow can be relieved.

Further, as described above, as the behavior of the dairy cow, when the dairy cow stands up from the sitting position, a strong force is applied to the front leg rather than the hind legs, and when standing from the standing position, the front leg moves. Stronger force is applied to the knees than the rear legs. Therefore, in order to deal with such a situation, in the beef bed mat 1 of the first embodiment, the part of the back surface layer 3 corresponding to the part of the surface layer 2 on which both front legs are stepped on is the surface on which both rear legs are stepped on. It is formed in a softer state than the portion of the back surface layer 3 corresponding to the portion of the layer 2 and the hemispherical recessed portion 22 is provided on the surface of the back surface layer 3 to provide a cow bed mat. By using 1,
The impact applied to the front legs and knees of a dairy cow can be properly softened. In addition, the hemispherical concave portion 22 provided on the surface of the back surface layer 3 prevents the cattle bed mat 1 from slipping on the cattle bed when the cattle bed mat 1 is laid on a cattle bed made of concrete or the like. can do.
