BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walk-through weight measuring device for measuring the weight of livestock such as cows and pigs by allowing the livestock to pass by walking. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a livestock walk-through weight measurement device that enables more accurate measurement.

[0002]

2. Description of the Related Art When breeding livestock such as cows, pigs, and sheep, which are mainly used for food, it is essential to measure their weight in order to manage their health. Conventionally, to measure the weight of livestock, conventionally, the livestock was simply placed on a large scale and the livestock was measured in a stationary state. However, in such a method, it is difficult to stop the livestock, so that the measurement is troublesome, and there is a problem that the measured value cannot be obtained with sufficient accuracy. In order to solve such a problem, in recent years, a walk-through automatic weighing-type weighing scale has been proposed and put into practical use, in which a livestock is allowed to walk on a weighing unit and the body weight is measured during the walking.

[0003]

[Problems to be Solved by the Invention] However, in such a walk-through weight scale, measurement can be performed with high accuracy when livestock walks quietly, but measurement accuracy deteriorates when running or jumping. There is a problem. The present invention has been made in view of the above circumstances, and a walking-pass type weight measuring device that measures the weight of livestock such as cows and pigs by walking livestock so that more accurate measurement can be performed. In addition, it aims at suppressing the walking speed of livestock.

[0004]

SUMMARY OF THE INVENTION Therefore, in a livestock walking-type body weight measuring device according to the present invention, a regulating body for regulating a walking path of livestock along the longitudinal direction of the weighing section is provided on both sides of the weighing section. Is provided so as to be movable in the width direction of the weighing unit, and these restrictors are inclined such that the lower lateral width of the livestock walking space formed by the weigher and the restrictor is narrower and the upper lateral width is wider. The above-mentioned problem was solved by arranging these regulating bodies so that the distance between them gradually narrowed from the entrance to the exit, so that the livestock could walk slowly on the weighing unit.

[0005]

According to the walking weight measuring device for livestock of the present invention, the body is slanted by arranging the regulating body so that the lower side of the walking space is narrow and the upper side is wide. The width of the walking space through which the foot part passes is wide, and the width of the walking space through which the foot part passes becomes narrow, so that when the livestock passes over the weighing section, it is prevented from running or jumping.
In addition, by providing the regulating body so as to be movable in the width direction of the weighing unit, it is possible to appropriately change the lateral width of the walking path according to the size of the body of the livestock. Furthermore, by arranging the regulation bodies so that the distance gradually narrows as going from the entrance to the exit, the width of the walking path formed between the regulation bodies gradually narrows, and thus the walking speed of the livestock traveling on the weighing unit increases. Are increasingly restricted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.
In these figures, reference numeral 1 denotes a livestock walking-type weight measuring device (hereinafter simply referred to as a weight measuring device). The weight measuring device 1 is composed of a measuring unit 2 for measuring the weight of a livestock while walking and passing the same, and a fence 3 for regulating the walking of the livestock.

As shown in FIG. 2, the measuring unit 2 is a rectangular weighing plate (weighing unit) 4 which is long and thin in a plan view, and is disposed below the weighing plate 4 as shown in FIG. A detection unit 5 having a built-in load cell (not shown) for receiving a load, and a weighing value obtained by the load cell as a signal, and calculating the input value to determine the weight of the livestock.
It consists of: The arithmetic processing unit 6 of the measuring unit 2 is further connected to a display unit 7 for displaying the weighed value determined by the arithmetic processing unit 6 and an output unit 8 for wirelessly outputting the weighed value. Here, the weighing plate 4 serves as a walking path for weighing the weight of the livestock, as described later, by allowing the livestock to walk along the longitudinal direction thereof.

The fence 3 is detachably fixed on the weighing plate 4 and is substantially vertically arranged on both sides of the weighing plate 4 along the longitudinal direction of the weighing plate 4 as shown in FIGS. As shown in FIG. 1, the fence main bodies 9, 9, and the regulating plates 10, 10, which are arranged inclining inside the fence main bodies 9, 9, respectively, are provided. As shown in FIG. 3, the fence main body 9 includes vertical members 9a # standing on the weighing plate 4, horizontal members 9b, 9b bridged over the upper ends of the vertical members 9a #, and vertical members 9a The reinforcing members 9c are disposed diagonally between the members 9b. The lower ends of the vertical members 9a # are fixed to the weighing plate 4 by screws.

The regulating plates 10, 10 are rectangular plates made of wood, plastic, iron, rubber or the like, both of which have a lower end disposed inside the weighing plate 4 and an upper end disposed on the inner surface of the fence 3. It is tilted in a leaning state. With such a configuration, the weighing plate 4 and the regulating plates 10, 1
In the walking space A formed by being surrounded by 0, the width on the weighing plate 4 serving as a walking path is narrow, and the width on the upper end side of the regulating plates 10 and 10 is wide. In addition, these regulating plates 1
As shown in FIG. 4, rod-like support rods 11 are horizontally mounted on the back surfaces of the support rods 0 and 10, respectively.
Are inserted through mounting holes 12 formed in a vertical member 9a of the fence main body 9 so as to be able to advance and retreat. The support rods 11 are all fixed to the fence body 9 by fixing the inner surface side and the outer surface side of the vertical member 9a by donut-shaped fixing plates 13, 13. Here, as shown in FIG. 5, a female screw hole 14 penetrating from the outer surface to the inner surface of the hole is formed in the fixed platen 13. A male screw 15 having a handle 15a is formed in the female screw hole 14. By being detachably screwed, the support rod 11 is pressed by the tip of the male screw 15 and is fixed in the hole of the fixed platen 13. And, with such a configuration, the regulating plates 10, 10
The position of the weighing plate 4 as shown by the two-dot chain line in FIG.
The width of the walking path formed between the restricting plates 10, 10 can be changed. In addition, these regulating plates 10, 10 are arranged with gradually decreasing intervals so that the walking path formed therebetween has a wide entrance P side and a narrow exit Q side, as shown in FIG.

The support bar 11 is attached to the back surface of the regulating plate 10 so as to be freely rotatable in the vertical direction, and the regulating plate 10 changes the angle between the regulating plate 10 and the supporting bar 11 to change the angle. The inclination angle can be changed. Thus, the regulation plates 10, 10 can appropriately adjust the difference between the upper and lower widths in the walking space according to the type of livestock.

In addition, as shown in FIG. 2, the weight measuring device 1 is provided with a gate section 16 on its entrance P side. The gate portion 16 includes a tread plate 17 placed adjacent to the weighing plate 4, frames 18, 18 erected on both sides of the tread plate 17, and guides mounted inside the frames 18, 18. And 19 parts. The step board 17 is formed with a gradient so as to eliminate a step between the ground or the floor surface and the weighing plate 4. Guide 1
9, 19 has a wide inlet side (the side opposite to the weighing plate 4),
The inside of the weighing plate 4 is made of an elastic body such as rubber formed into a curved surface so that the weighing plate 4 side becomes narrow. It is configured so as to substantially match the width between the lower ends.

In order to measure the weight of a domestic animal, for example, a cow, using such a body weight measuring and measuring apparatus 1, first, the width of the walking space through which the body of the cow passes increases according to the body shape of the cow. In addition to adjusting the positions of the restricting plates 10, 10, the inclination angles of the restricting plates 10, 10 are adjusted so that the lateral width of the walking space through which the feet pass is reduced. Next, the gate unit 1
The cow is guided to 6 and walked on the weighing plate 4 through the gate section 16. In this case, the guide sections 19, 1 of the gate section 16
As the distance between the nine is gradually reduced, even if the cow runs, the cow slows down at the gate 16 and the cow smoothly enters the walking space A on the weighing plate 4 without delay. In the walking space A, as shown in FIG. 1, the cow B does not run or jump because the width of the foot is limited by the regulating plates 10, 10, and stops or stops on the way. And slowly walk on the weighing plate 4 without increasing the walking speed. Also, at this time, the gap between the regulating plates 10 and 10 gradually narrows toward the exit Q side, so that the width of the walking path gradually narrows, so that the cow walks more slowly as it proceeds along the walking path.

During this time, the measuring unit 2 is turned ON, so that the load received by the weighing plate 4 is detected by the detecting unit 5 as a weighing value. Calculate the body weight. Here, the load of the fence 3 arranged on the weighing plate 4 is previously input to the arithmetic processing unit 6 as a tare, and the weight calculated by the arithmetic processing unit 6 indicates the true weight of the cow. Becomes Further, the weight value calculated by the arithmetic processing unit 6 is displayed on the display unit 7, the administrator confirms the weight value, and the weight is displayed on a data carrier (not shown) attached to the cow in advance by the output unit 8. Enter a value. Here, the data carrier is capable of wirelessly writing various information from the output unit 8 and reading information written by the output unit 8 or another reader. In addition, as a result of repeating many experiments, in the case of a cow weighing 300 to 700 kg, FIG.
It has been found that setting t ₁ and t ₂ to 25 cm and 75 cm, respectively, is most effective for passing the cow at a slow speed without rash. In addition, weight is 50-1
In the case of a calf weighing 00 kg, the width was too wide, and the walking speed could not be sufficiently suppressed.
0 and move t ₁ and t ₂ in FIG. 1 to 25 cm and 65 cm, respectively.
As a result, the calf also began to walk at a sufficiently slow speed.

In the thus-configured body weight measuring apparatus, the width of the walking space A for livestock on the weighing plate 4 is reduced by the regulating plates 10 and 10 so that the foot side of the livestock is narrow and the trunk side is wide. When walking on the weighing plate 4, for example, livestock does not run or jump as if a human walks slowly on a balance beam, and does not stop or increase the walking speed halfway. The person slowly and carefully walks to the exit, thereby improving the accuracy of the weight measurement in the measuring section 2. In addition, the regulating plate 10,
By arranging 10 so as to be movable in the width direction of the weighing plate 4, it is possible to appropriately change the width of the walking path according to the size of the livestock such as cows, and thus to measure the weight of a plurality of livestock. In addition to this, it is possible to measure the weight of livestock of the same species in an optimal state according to the size of the physique. Furthermore, by arranging the regulating plates 10 and 10 so that the interval gradually narrows as going from the entrance P side to the exit Q side, the width of the walking path formed between the regulating plates 10 and 10 is gradually narrowed, As the walking speed of the livestock moving on the weighing plate 4 increases, the accuracy of the measurement can be further improved, especially in the latter half of the weighing plate 4 which gives important data for weight calculation.

In the above embodiment, the regulating plates 10, 10 are provided so as to be movable in the width direction.
The support rod 11 attached to the back of the fence is inserted into the fence body 9 so as to be able to advance and retreat, but the present invention is not limited to this, and the restriction plates 10, 10 can be moved in the width direction by other known means. Good. In the above embodiment, the gate portion 16 is provided separately from the weighing plate 4. However, the gate portion 16 may be integrated with the fence 3 and installed on the weighing plate 4. As in the case of 3, the input is made as a tare. Further, when the gate portion 16 is installed on the weighing plate 4 integrally with the fence 3, the guide portions 19, 19 are moved in the width direction of the weighing plate 4 by, for example, the same configuration as that of the regulating plates 10, 10. The distance between the guide portions 19, 19 on the exit side and the regulating plates 10, 10
It is preferable that the inner surface of the guide portion 19 and the inner surface of the regulating plate 10 are continuous with each other so that the interval on the entrance side of the guide plate is matched.

[0016]

As described above, in the livestock walking-type weight measuring device of the present invention, the width of the walking space through which the trunk of the livestock passes is wide, and the width of the walking space through which the feet pass is narrow. In this way, it is possible to prevent livestock from running or jumping when passing through the walking space on the weighing unit, so that the weight of livestock can be measured with higher accuracy. Can be. In addition, since the regulating body is disposed so as to be movable in the width direction of the weighing unit, the width of the walking path can be appropriately changed according to the size of the body of the livestock. In addition to being able to be used, the weight of livestock of the same species can be measured in an optimal state according to the size of the physique. Furthermore, since the regulating bodies are arranged so that the interval gradually narrows as going from the entrance side to the exit side, and the width of the walking path formed between the regulating bodies is gradually narrowed, the walking of livestock traveling on the weighing unit is performed. As the speed increases, the accuracy of the measurement in the latter half of the weighing unit, which gives important data for the weight calculation, can be further improved, and as a result, the weight of the livestock can be measured very accurately. .
