Description

[Detailed Description of the Invention] This invention relates to an improvement in a hopper-type automatic feeder used especially in poultry house equipment.

Generally, this type of feeder is equipped with a self-propelled cart mounted above the chicken housing cage using a drive device, and while the cart is reciprocated vertically along the cage, each stage is fed from a hopper provided on the cart. It has been proposed that feed is supplied to the cage.

An example of this feeder will be described with reference to FIGS. 1 and 2. A chicken housing cage 1 is constructed in two stages, upper and lower, and is mounted opposite to a column 2 of a poultry house apparatus. Above this cage 1 are two rails 4 of a trolley 3,
5 is arranged on a support member 6 fixed to the pillar 2. Wheels 7 running on the rails 4 and 5 are rotatably attached to the tips of two frame members 8, and are driven by a drive device (not shown) installed between these frame members 8. be done. A feed pipe 10 is connected to the feed tank 9 outside the poultry house equipment, and an auger, which is a coiled transfer member, is installed inside this supply pipe 10. By rotating this auger with a separate drive device, the feed can be fed. is filled from above through the supply pipe 10 from the tank 9 into the hopper 11 supported between the frame members 8. As shown in FIG. 2, an auger 12a driven by a drive device, that is, a motor 12, is attached to the bottom of each hopper 11, and feed in the hopper is sequentially transferred to an outlet 11a by this auger 12a.
The feeding troughs 1a of the cages 1 in each stage are supplied through the hoses 13. This type of feeder therefore fills each hopper 11 with a predetermined amount of feed from the feed pipe 10 at the end of the row of cages.
Next, the cart 3 moves on the rails 4 and 5 to feed the feed in the hopper 11 to each trough 1a, and is normally controlled so that one feeding is completed when the cart makes one round trip. There is.

However, even if a fixed amount of feed is supplied into the feeding trough 1a in this way, the amount of food eaten by each chicken varies, so there will inevitably be parts of the trough after feeding that have completely eaten the food and other parts that have not. There will be uneaten portions. However, since the amount of feeding each time is preset on the assumption that all the chickens will eat all the food at one time, when the next feeding is carried out, there will likely be insufficient food in the part of the chicken that has eaten all the food. However, the uneaten portion was supplied with extra food, resulting in wasted food consumption. Therefore, with this kind of equipment, it is not possible to feed the chickens the desired amount of food, which not only has a negative impact on the breeding management of chickens, but also
This had the disadvantage of unnecessarily increasing feed costs.

The purpose of this invention is to provide a new hopper-type feeder that allows chickens to feed in accordance with the amount of food they actually eat and to accurately grasp the amount of food fed.

Next, this invention will be described with reference to the embodiment shown in FIG. 3, in which the same parts as in the conventional example shown in FIGS. 1 and 2 are designated by the same reference numerals.

FIG. 3 shows a row in which this invention is applied to the hopper shown in FIG. 2, in which a sensor 14 is provided near the feeding trough side end 13a of the hose 13 to detect the presence or absence of feed in the hose 13. There is. This sensor 14 can be, for example, a mechanical sensor or a light- or pressure-sensitive sensor, which
When a predetermined amount of feed remains in a, the feed is supplied to the controller 15 as an output signal. When the controller 15 receives the output signal from the sensor 14, it gives a command to the motor 12 to stop the operation of the motor 12 and interrupt feeding by the auger 12a, and also stops the motor 12 when there is no signal from the sensor 14. Activate auger 12
a so that the feed in the hopper 11 is supplied into the hose 13. Further, the motor 12
A rotation speed detector 16 is connected to the rotation speed detector 16, which detects the rotation speed of the motor and sends it as an output signal to the feeding amount measuring device 17. Does this feeding amount measuring device 17 have a display unit itself?
Alternatively, a display section is connected separately, and the amount of feed supplied by the auger 12a is calculated based on the rotation speed signal of the motor 12 obtained by the rotation speed detector 16, and the feed amount is displayed on the display section in an analog or digital manner. It is designed to be displayed. Note that the mounting position of the sensor 14 is appropriately selected and determined based on the rotation speed of the auger 12a, the diameter of the hose 13, and the like.
Moreover, the controller 15, the rotation speed detector 16, and the feeding amount measuring device 17 may not be provided independently, but may be configured integrally.

With the above configuration, the feeder is activated, the auger 12a starts to feed feed to the feeding trough 1a, and the feeding trough side end 13 of the hose 13
As shown in the figure, when the feed starts to stay and the amount exceeds a predetermined amount, the sensor 14 detects this and informs the controller 15, and the controller 15 stops the rotation of the auger 12a, so that feeding stops and the feed trough 1a is stopped. This prevents excess feed from being supplied to the feeder. Conversely, if there is no predetermined amount of feed in the end portion 13, the controller 15
Since necessary feeding is carried out by rotating the feeding trough 2a until the amount of feeding is detected by the sensor 14, it is possible to eliminate the shortage of food in the feeding trough 1a. Furthermore, the motor 12 of each hopper 11 has a rotation speed detector 1.
6 and the feeding amount measuring device 17,
The amount of food fed by the auger 12a can be accurately measured and displayed.

Therefore, according to this invention, since the auger 12a can intermittently supply feed according to the amount of residual feed left in the feeding trough 1a during the previous feeding, the actual It becomes possible to carry out feeding that promotes the amount of foraged food. Furthermore, the feed amount is accurately measured by the feed amount measuring device 17 and displayed for each cage on each tier on the display section, which is extremely convenient for the management of raising chickens.
