Description
Technical field
The present invention relates to a kind of crib of supplying with poultry feed, particularly about the automatic blanking crib of a kind of raise poultry.
Background technology
Large-scale breeding poultry mostly adopts strip crib (as shown in Figure 1) as the breeding house of raising chicken, crib is suspended on outside filter, the cell body of crib is by Internal baffle 1(first baffle plate adjacent with filter), connect the base plate 2 of Internal baffle 1, and the outer baffle 3(second baffle of and connecting bottom board 2 relative with Internal baffle 1) composition, wherein, the bottom of outer baffle 3 has one section from starting the tilting section 31 tilted to cell body with base plate 2 joints, the object that this tilting section 31 is set is when along with searching for food of chicken, clout reduces, feed is concentrated to cell body bottom, prevent that clout from disperseing, be convenient to searching for food of chicken.When raising, add feed in cell body by artificial or mechanical system, chicken stands in filter head is reached in cell body and searched for food from filter gap, adopts this kind of crib, chicken can not step on leg in cell body, the feed of can not making dirty, simultaneously conveniently again adopts artificial or mechanical system is reinforced, is therefore widely used.But in feeding process, find that the number of feeding quantity and the wastage of feed have very large relation, through test statistics, fill it up with crib if disposable, feed waste is up to 40～50%; If be added to 2/3 of crib, waste 12% left and right; If be added to 1/2 of crib, waste 4～5%; Be added to 1/3 of crib, waste 1～2%.In order to reduce the waste of feed, prior art is mostly to adopt repeatedly reinforced method, and even more times adds in crib to divide three times by the feed of a day, but repeatedly reinforced in one day, not only strengthen the labour intensity of hand fed, and increased the stress reaction of chicken.Chicken generally has the instinct of the fresh feed of looking for food, and the intragroup individuality of chicken also has dividing of advantage, weak tendency, according to experimental observation, feed is added in crib at every turn, first chicken in strong position searches for food, until searched for food, the chicken that just can take turns to relative weak tendency searches for food, even if surging chicken has had enough, if there is again new feed to be added in crib, surging chicken can push through again the fresh material of searching for food, excessive with regard to causing surging chicken to search for food like this, concerning chicken group, can cause feed intake inequality.For saving cost, feed lot generally all adopts mash feed at present, in feed, the particle size of various materials differs, because chicken has habit particular about food, while searching for food, can first select the feed grain that particle diameter is large and peck at, when weak tendency chicken searches for food, the feed grain that often only remaining particle diameter is little, the nutrition inequality that causes the chicken successively searching for food to take in, affects the conversion ratio of feed and the productivity of chicken.Therefore, the forage volume in minimizing crib can reduce the difference that affects composition of the feed of the chicken picked-up of successively searching for food.But, adopt this common crib to reduce the forage volume at every turn adding in crib and achieve the goal by increasing the reinforced frequency.
A kind of automatic blanking crib for raising chicken is disclosed in prior art, one dividing plate with holes is set in this crib cell body cell body is divided into search for food district and buffer storage area, dividing plate be one take top the swingable plate as axis of rotation, dividing plate bottom is positioned on base plate, and leave gap with backplate surface, form discharging opening, and base plate to Internal baffle direction tilt, inclination angle is 15 °～20 °.When use, feed is added in buffer storage area, feed flows into from discharging opening the district of searching for food along bottom board inclined plane, searches for food for chicken.Above-mentioned crib after tested, even when inclination angle is set to 20 ° of the upper limits of its proposition, also cannot guarantee that Feed Energy under static state normally glides, must beat cell body or dividing plate by artificial external force, feed could continue to flow out from discharging opening under the ordering about of vibration force, if strengthen again the inclination angle of base plate, the chicken feed at base plate and Internal baffle angle of cut place of can not normally searching for food.For this reason, the method provides a kind of vibrative method of pecking at by chicken that feed is flowed out from discharging opening, its mentality of designing is: in the time that buffer storage area is equipped with feed, chicken sees from district's one side of searching for food the feed exposing dividing plate aperture, when after the discharging opening cutout of the bottom, district of searching for food, the chicken feed of pecking at from aperture, while pecking at, all dividing plate is produced to percussion power at every turn, because dividing plate swings take top margin as rotating shaft, so this percussion power can promote dividing plate and apply a vibration force to buffer storage area direction, vibration force can make the feed of discharging opening again flow out.But the method is not considered the dietary habit of chicken, in the time that reality is used, not only can not contribute to the outflow of feed, can make on the contrary discharging opening stop up more severely, mainly because chicken has and turns over the habit of taking off feed, also have simultaneously and like oarse-grained habit particular about food, when flowing out to from discharging opening, feed searches for food bottom, district, take off habit if do not consider turning over of chicken, really discharging opening will be blocked as long as flow out a small amount of feed, after chicken searches for food a small amount of feed of this outflow, feed below can continue to flow out cover, find in actual field, chicken constantly claws the feed at discharging opening place at the middle meeting beak of searching for food, be deposited into Internal baffle one side near chicken place, be rolled down and block discharging opening completely and chicken cannot claw virgin material from discharging opening again until be deposited into the feed of eminence, chicken is in the situation that can not searching for food fresh large particle diameter material from the bottom, district of searching for food, in the aperture that can transfer to expose from dividing plate, peck at, while causing discharging opening place there is no feed after the cutout of discharging opening place, adopt the mode that increases like this vibration to promote that the outflow of feed should be effective, but when discharging opening place is flowed out to after stifled the expiring of feed in the district of searching for food, again by the mode of vibrating, can only make the feed of buffer storage area shake more real and more real, shake tighter and tighter, after the feed that chicken has been flowed out the district of searching for food has been searched for food, the feed of buffer storage area again cannot flow out from discharging opening.
In sum, because having to turn in the process of searching for food, chicken takes off feed and habit particular about food, search for food in process whole, the forage volume that district can take in of searching for food is fewer, the leeway that chicken can select is just less, the difference of the nutrient component of the feed that chicken is taken in of successively searching for food is just less, wherein, the size of the distance of dividing plate and Internal baffle determined the to search for food capacity in district, dividing plate is less apart from the distance of Internal baffle, the district's feed amount of taking in of searching for food is less, but the size of above-mentioned distance must be greater than the head sizes of chicken, just can make chicken normally search for food, this makes this distance be difficult to dwindle, how to make the chicken can be normal, the stable feed amount of taking in of searching for food and can reduce the district of searching for food is a urgent need to solve the problem.
