Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a livestock weighing device for measuring the weight of livestock such as pigs, and more particularly to a livestock weighing device for allowing livestock to pass through a weighing space for weighing.

[0002]

2. Description of the Related Art Conventionally, as a livestock weighing apparatus of this type, there is one shown in FIGS. That is, a weighing space 2 through which livestock 1 such as pigs can pass is formed by a partition frame 3, and a weighing platform 4 is arranged on the lower surface of the weighing space 2. The weighing space 2 is set to a distance L of, for example, 3 or 4 steps which is a prescribed number of steps when the livestock 1 is in a normal walking state, and the weighing platform 4 observes a change in the weight value signal of the weighing platform 4. A data processing device 5 for predicting weight is connected.

At the entrance of the measuring space 2, an electric gate device 6 which can be opened and closed to the left and right is arranged as shown by a virtual line in FIG. This gate device 6 is opened and closed by a staff member according to the movement of the livestock 1 so that the subsequent livestock 1 does not enter the weighing space 2 at the same time.

[0004]

However, in the above-described conventional livestock weighing apparatus, the livestock 1 that is about to enter the weighing space 2 on the weighing platform 4 and the succeeding livestock 1 are separated from each other. In addition, there is a problem that a staff member who constantly opens and closes the gate device 6 is required, which is troublesome.

The present invention solves the above problems, and an object of the present invention is to provide a livestock weighing apparatus which does not require the trouble of opening and closing a gate.

[0006]

In order to solve the above problems, the present invention forms a weighing space through which livestock can pass by a partition material, and places a weighing platform on the lower surface of the weighing space.
In a livestock weighing device that introduces livestock from the entrance of the weighing space and predicts the weight by observing the change of the weight value signal when the livestock passes on the weighing platform, place the location above the entrance of the weighing space. An upper door body is provided that is rotatable around the transverse axis centering across it from the hanging position to an upper position in the weighing space, and comes into contact with the upper portion of livestock entering the weighing space. A flexible lower shield is attached to the upper door, which extends outward from the upper door and is integrated with the upper door when the upper door is abutted and pushed up by the entry of livestock. It is equipped with an entrance prevention door that rotates and its end moves downward to the vicinity of the lower surface of the approach space to the weighing space, and blocks subsequent animals from entering the weighing space.

[0007]

In the above structure, livestock such as pigs have a habit of pushing forward with this member as long as it is a member that moves lightly by pushing with its nose, so that even if there is a lower shield at the place to enter. , The lower shield is pushed away with a nose etc. to enter the weighing space on the weighing platform, and then the upper door body comes into contact with the upper part of the livestock and the livestock moves forward even if some regulation force is applied. Then, the upper door is rotated to the upper position in the measuring space. At the same time, the entry prevention door rotates integrally with the upper door body, and the end portion of the entry prevention door moves down to near the lower surface of the entry path to the weighing space. As a result, subsequent entry of the livestock into the weighing space is blocked by the entry prevention door, and the weight of one livestock is accurately measured. After that, when the upper door body separates from the body of the livestock that has entered the weighing space, the upper door body returns to the hanging position, and the following livestock similarly enters the weighing space.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The same functions as those of the conventional one are designated by the same reference numerals and the description thereof will be omitted.

An upper door body 12 is rotatably attached via a bracket 11 to the upper side portion 3a of the partition frame 3 which crosses left and right above the entrance of the measuring space 2. The upper door 12 is rotatable about a supporting portion 12a from a hanging position to an upper position in the measuring space 2, and a spring member (not shown) provided in the supporting portion 12a causes the upper door 12 to move in the hanging position direction. Is urged by. In addition, 11a is a stopper portion that regulates the position of the upper door 12 so as not to rotate outside the hanging position.

At the lower end of the upper door body 12, a lower door body 13 as a lower shield body, the lower end of which extends to the vicinity of the weighing platform 4, is provided.
Is rotatably mounted on a shaft. In addition, an entrance prevention door 14 extending outward is integrally attached to the upper door body 12, and the entrance prevention door 14 is provided in the upper door body 1.
When 2 is pushed up, it is rotated downward together with the upper door body 12 so that the lower end approaches the vicinity of the lower surface of the approach path.

In this embodiment, the case where the livestock 1 is a pig is illustrated. The partition frame 3 as a partition member is attached to the weighing platform 4, and moving wheels 15 are provided on both sides so that the wheels 15 can move downward and forward. Further, an inclined table 16 for facilitating the entry and exit of the livestock 1 is arranged in front of and behind the weighing platform 4, and a supporting member 17 extending from the inclined platform 16 is engaged with the leg portion 4a of the weighing platform 4. The separation between the weighing platform 4 and the tilt platform 16 is prevented.

In the above structure, when the livestock 1 such as a pig is pushed from the rear, the lower door 13 is pushed forward in order to enter the weighing space 2 side. Since the lower door body 13 is simply hanging, the livestock 1
You can push it away with your nose. After that, even if the upper door 12 comes into contact with the upper part of the livestock 1 and the biasing force of the spring member acts, the livestock 1 advances as it is due to its habit, and as shown in FIG. It is rotated to the upper position in the space 2. At the same time, the entry prevention door 14 rotates downward together with the upper door body 12, and the end portion of the upper door body 12 approaches the vicinity of the lower surface of the entry path. As a result, subsequent entry of the livestock 1 into the weighing space 2 is blocked by the entry prevention door 14 to be reliably separated from the preceding livestock 1, and the weight of one livestock 1 is accurately measured. After this, when the upper door body 12 separates from the body of the livestock 1 that has entered the weighing space 2,
The upper door 12 returns to the hanging position, and the following livestock 1 similarly enters the weighing space 2.

In the above embodiment, the case where the lower door body 13 is rotatably attached below the upper door body 12 has been described, but as shown in FIG. 4, the hanging curtain 18 is attached to the lower side of the upper door body 12. However, the same effect can be obtained. Further, although the case where the livestock 1 is a pig is illustrated in the above-mentioned embodiment, it is needless to say that the present invention can be applied to livestock having a similar habit.

[0014]

As described above, according to the livestock weighing apparatus of the present invention, an upper door body that is rotatable and abuts against the upper portion of the livestock is provided at the entrance of the weighing space, and the lower end of the upper door body is provided. Since a lower shield that moves with a small force is attached, and the upper door is equipped with an entry prevention door that rotates integrally with the upper door to block entry of the following livestock into the weighing space, By using the habit of livestock, it is possible to reliably separate the preceding and following livestock, eliminating the need to open and close the conventional gates, simplifying the configuration and improving operability to save labor. it can.
