DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a mixing means for mixing a plurality of types of feed, and a discharging means for discharging the feed mixed by the mixing means to a feed receiving section for feeding the feed to livestock. The present invention relates to a provided feed mixing device.

[0002]

2. Description of the Related Art Such a feed mixing device mixes a plurality of types of feeds having different forms and nutrients in a distribution amount (so-called feed design) set so as to have a nutritional balance suitable for the livestock to be bred. And feed them to livestock. Conventionally, a plurality of types of feeds are simply mixed by a mixing means, and the mixed feed is discharged to a feed receiving unit by a discharge means.

[0003]

By the way, some types of feed have good and bad tastes for livestock. However, as in the past, simply mixing a plurality of types of feeds makes it easy to separate different types of feeds. However, there is a problem that feed with poor palatability is left without eating. Therefore, conventionally,
Livestock could not be fed a nutritionally balanced feed as designed. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a feed mixing device that allows livestock to feed a nutritionally balanced feed as designed.

[0004]

According to the first aspect of the present invention, water is supplied to the feed mixed by the mixing means by the water supply means. Adhesion by water makes separation difficult. Furthermore, when the feed contains carbohydrates or proteins, the addition of water increases the adherability of the feeds due to the carbohydrates and proteins, making the feed more difficult to separate. Therefore, livestock
It is not possible to select and eat only feeds with good palatability, and all mixed feeds will be eaten together in a mixed state, and livestock will be fed a nutritionally balanced feed as designed for feed And a feed mixing device capable of performing such a feed mixing. In addition, feed that has become moist due to the addition of water has improved palatability for livestock and increases feed intake of livestock, as compared to feed in the dry state, and thus improves the growth of livestock. You can now plan. In addition, even if a powdery feed is contained, the addition of water can prevent the powdery feed from being sucked into the respiratory tract of the livestock.

According to the second aspect of the present invention, since water is supplied to the feed mixed by the mixing means in a sprinkling state, even if water is supplied to the feed mixed by the mixing means, Variations in the water content of the feed after mixing can be reduced.

According to the characteristic feature of the third aspect, the water is supplied to the point where the feed is mixed by the mixing means during the operation of the mixing means. Can be prevented from scattering and adhering to the device. Incidentally, water can be supplied to the feed before the feed is mixed by the mixing means. However,
In that case, the supplied water causes the feed to adhere to a feed supply unit or the like that supplies the feed. On the other hand, according to the characteristic configuration of the present invention, since the feed in a dry state is supplied by the feed supply unit, it is possible to prevent the feed from attaching to the feed supply unit and the like. . Therefore, the maintenance of the apparatus can be reduced.

According to a fourth aspect of the present invention, a plurality of types of feed are supplied to a storage unit provided on the moving body by feed supply means provided on the ground side, and a plurality of types of feed are stored in the storage unit. The feed is mixed by mixing means, and
Water is supplied to the feed mixed by the mixing means by the water supply means. Then, when the moving body travels along the traveling route, the feed mixed by the mixing means is discharged by the discharging means during the traveling to the feed receiving unit continuously provided along the traveling path of the moving body. Discharged continuously. In other words, at any position of the feed receiving unit, a required amount of feed can be supplied to each of the plurality of livestock, and in such a configuration, the nutritional balance of the livestock according to the feed design is provided. You can now feed.

[0008] According to the characteristic configuration of the fifth aspect, in a state where the moving body is located at the receiving position, a plurality of types of feed supplied from the feed supply means are received in the storage unit provided in the moving body, When the reception of the feed is completed, the moving body is caused to travel along the traveling route. And in such a configuration, the water supply means supplies water to the storage unit when the moving body is located at the receiving position,
It is provided on the ground side. Therefore, since it is not necessary to mount a water storage tank or the like on the mobile body for storing water to be supplied to the feed mixed by the mixing means, it is possible to avoid an increase in the size and weight of the mobile body. Further, it is possible to avoid a decrease in operability such as running the moving body while drawing a water supply hose connected to the water supply means.

Is smaller than the maximum water absorption WA, a timing setting means R2 for setting the operation timing of the beat pulp conveyor 2a, the water supply shower 4, and the bucket conveyor 2b is provided.

The calculating means R sets the total water supply amount WWT so that the water content relative to the sum of the set input weights (WFH + WF1 + WF2 + WF3) becomes the set water content SR. Further, when the set total water supply amount WWT is larger than the maximum water absorption amount WA, the calculating means R sets the water supply amount WW1 to a value slightly larger than the maximum water absorption amount WA, and sets the set total water supply amount WWT.
The water supply amounts WW2 and WW3 are set by proportionally distributing a value (WWT-WW1) obtained by subtracting the water supply amount WW1 from the WT from the ratio of the set input weights WF1 and WF2. Then, the supply amount adjusting means S controls the water supply shower 3 so that the set water supply amount WW1 is supplied when the beet pulp is supplied, and the supply water amount W when the compound feed is supplied.
The water supply shower 23 is controlled so that water of W2 is supplied and water of the set water supply amount WW3 is supplied at the time of supplying plain feed. When the set water content SR is set within a normal set range (for example, about 10 to 40%), the set total water supply amount WWT is larger than the maximum water absorption amount WA.

In the bucket 2f, there is water-containing beet pulp and water not absorbed by the beet pulp. Therefore, when the beet pulp flows down from the bucket 2f, the water that has not been absorbed by the beet pulp promotes the downflow of the beet pulp, so that the beet pulp is prevented from adhering to the bucket 2f.

In the standby state where the feeding work vehicle A is stopped at the standby position, the controller 15 uses the detection information by the rotary encoder L and the travel amount detection means M every time the scheduled feeding start time TSA is reached.

The control operation is started by turning on a start switch provided on the control panel J. When the current time T reaches the scheduled start time TSB of the feed scraping operation (# 1), the feeding work vehicle A is moved along the feed receiving unit 1. When the current time T reaches the scheduled work start time TSA (# 3), based on the detection information of the rotary encoder L, the feeding work vehicle A moves to the standby position. Is determined (# 4), and when the feeding work vehicle A is stopped at the standby position, the set input weights WFH, WFH, of the various feeds set corresponding to the feeding operation at that time are determined.

The beet pulp and water in f are fed down to the feed hopper 5 in a state where water that has not been absorbed by the beet pulp exists, that is, almost all of the set water supply amount WS4 is absorbed by the beet pulp. As shown, beet pulp conveyor 2a, water supply shower 4, and bucket conveyor 2b
Is set (# 7).

The operation timing is set such that as the set water supply amount WS4 is smaller than the maximum water absorption amount WW, water supply is started later than the start of feeding of beat pulp to the bucket 2f by the beat pulp conveyor 2a. The water supply amount per unit time of the shower 4 and the water supply start timing are set, and the driving speed of the bucket conveyor 2b is set so that the bucket 2f moves to the charging position at high speed.
