Description
Technical field
The utility model belongs to cultivation equipment field more particularly to charging tray is used in a kind of poultry.
Background technique
Increasingly increase with the development and people of China's economic to green agricultural product demand, more and more funds are thrown
To agriculture field, pro-gaze of the green agricultural products such as chicken, thin and small hen increasingly by the investor that changes one's profession, outdoor breeding puts soil in a suitable place to breed
Chicken, thin and small hen cultivation become more and more hot, and the meat of the chicken cultivated in this way is apparently higher than the meat of indoor cage bird, and quality is also more
It is good, it is more and more raise chickens families using free-ranging by the way of come raising chicken, but the mode of free-ranging is taken to face a series of problems, it is logical
By device for feeding, the drinking-water of chicken is carried out the feeding of normal free-ranging chicken by drinking device, is carried out by two different devices,
Chicken finishes off when water removes to eat feed on mouth with water stain under normal conditions, and the feed that inevitably will lead in charging tray is got wet, long
And the long feed that will lead to goes mouldy because being infected with moisture dampness, is sticked on charging tray bottom wall, eats if carrying out cleaning chicken not in time
When the feed to go mouldy to these, it will lead to entire chicken group and fall ill, will cause Large Scale Death when serious, brought to raiser
Biggish economic loss, another, since charging tray is close from the ground, when filth is easy to be splashed into or even some chickens eat food,
Usually foot is also entered into charging tray, is unfavorable for the dietetic hygiene of free-ranging chicken, increases the factor of illness, therefore charging tray of raising chickens needs
Periodic cleaning, it is sick because having the feed of mildew pollution to avoid chicken group;But existing most of poultry charging tray, it is inconvenient
In cleaning, larger inconvenience is brought to keeper, therefore one kind is convenient to clean charging tray poultry charging tray and is just particularly important.

The second arc panel 18 rotated coaxially with cylindrical bar 14 and with the cooperation of the second arcuate socket 16, the storage are rotatably connected in slot 17
2 bottom wall lower end of batch can is fixed with the boss 19 being slidably matched with 4 roof of the second cylinder, is equipped with cavity 20 and cavity 20 in boss 19
It is inside fixed with servo motor 21, the cylindrical bar 14 drives through servo motor 21.
When in use, when needing to feeding in charging tray 1, keeper controls servo motor 21 to the embodiment
Rotation is to make cylindrical bar 14 that flabellum 15 be driven to be rotated, multiple second arcs rotated coaxially at this time with cylindrical bar 14
Plate 18 also rotates with it, and when original state, the second arcuate socket 16 is blocked feed completely and is in storage tank 2 by the second arc panel 18
Interior, when the second arc panel 18 is rotated with cylindrical bar 14, the second arcuate socket 16 is opened at this time, is now placed in storage tank 2
Feed is slid by the second arcuate socket 16 down along boss 19 under the agitation of flabellum 15, is eaten to drop down onto charging tray 1 for chicken group
With after blowing, keeper controls servo motor 21 and stops working, and the second arc panel 18 seals the second arcuate socket 16 completely
Stifled, blowing stops at this time;Preferably, it can be controlled after servo motor 21 rotates N circle and be stopped by servomotor controller, at this time the
Two arc panels 18 restore under the drive of servo motor 21 to original state, i.e. the second arc panel 18 is complete by the second arcuate socket 16
It blocks, it is discharging time that servo motor 21, which rotates N and encloses this process duration,.
Embodiment 3, on the basis of embodiment 1, the positioning device include being set to 1 bottom wall of charging tray and being located at plectane 11
Bolt 23 is combined in two threaded holes 22 and threaded hole 22 of lower section, the bolt 23 contacts at 11 lower end surface of plectane.
The embodiment when in use, in 1 bottom wall of charging tray and is located at below plectane 11 equipped with threaded hole 22, passes through screw thread
Hole 22 is combined with bolt 23, and the vertical one end of bolt 23 contacts at 11 lower end surface of plectane, positions to realize and clamp plectane 11,
Guaranteeing that the feed being located in charging tray 1 will not be rotated because of plectane 11 makes the first arcuate socket 9 open and then trickle down out of first arcuate socket 9
To ground, when needing to clear up charging tray 1, reversely screwing bolt 23 is detached from it with plectane 11, and plectane is in certainly at this time
By state, keeper is realized by flap shutter 5 and is cleared up charging tray 1.
Embodiment 4, on the basis of embodiment 1, the baffle 5 are arranged with 1 bottom wall matching part of charging tray in up-side down triangle.
The waste material being sticked on charging tray 1 mixes to be sticked on 1 bottom wall of charging tray with moisture because making moist, by baffle 5 and 1 bottom wall auxiliary section of charging tray
Position is set as up-side down triangle, can preferably scrape off the waste material being sticked on charging tray 1.
Embodiment 5, on the basis of embodiment 1,2 top of storage tank are equipped with feed opening 24.It is needed when in storage tank 2
When supplement feed, feed is added into storage tank 2 by feed opening 24.
The utility model provides a kind of poultry charging tray, is rotatably connected in the charging tray 1 and is slidably matched with 1 bottom wall of charging tray
Charging tray 1 is divided into multiple and different partitions by baffle 5, multiple baffles 5, and convenient for chicken group's feeding, 1 bottom wall of charging tray offers multiple the
The first arc panel 12 reversely rotated coaxially with baffle 5 is rotatably connected in one arcuate socket 9 and the first arcuate socket 9, it is clear when needing
When managing the waste material residue on 1 bottom wall of charging tray, for flap shutter 5 to drive the first arc panel 12 to rotate backward, baffle 5 will be sticked to material
Waste material on 1 bottom wall of disk scrape off and the waste material that is sticked on the first arc panel 12 when sliding into first sliding groove 10 by first sliding groove 10
