A kind of open-and-close mechanism in the automatic feeding device of poultry
Technical field:
The present invention relates to the open-and-close mechanism in a kind of automatic feeding device of poultry.
Background technology:
The structure of the existing automatic feeder for poultry is commonly:Grain is concentrated and is placed in grain storehouse, grain is from grain storage
Slid in storehouse in basin on the feed, after feeding the grain in basin and being eaten up by poultry, due to Action of Gravity Field, the grain meeting in grain storehouse
Fed into feed basin.In use, feed can be accumulated in food basin this kind of structure, can then block the discharging of feeder
Mouthful, often need to clear up discharging opening in use, using very inconvenient.
Therefore, it is necessory to be improved to prior art to solve the deficiency of prior art.
The content of the invention:
The present invention is to provide opening in a kind of automatic feeding device of poultry to solve the problem of above-mentioned prior art is present
Close mechanism.
The technical solution adopted in the present invention has:A kind of open-and-close mechanism in automatic feeding device of poultry, the opening-closing machine
Structure is located at the discharge outlet of grain storehouse, including baffle plate, switchboard, guide rod, back-moving spring, pinch roller, pin and floating spring, described
Baffle plate is provided with discharge opening, and baffle plate is fixed on the discharge outlet of grain storehouse, and switchboard is located at the lower section of baffle plate and going out baffle plate
Expect hole closing, one end of guide rod is fixed on switchboard, and the other end is plugged on baffle plate, and back-moving spring is sheathed on guide rod, and
One end is connected on switchboard, and the other end is connected on baffle plate;Pin is plugged on switchboard, and the upper and lower ends difference of pin
Stretch in outside switchboard, floating spring is sheathed on pin, and the upper and lower ends of floating spring are connected to pin and switchboard respectively
On, pinch roller is rotatably connected on the upper end of pin, and pinch roller is contacted on the lower surface of baffle plate by floating spring.
Further, the lower surface of the baffle plate is provided with guide groove and escape groove, and the guide groove is mutually passed through with escape groove
It is logical, and depth of the depth more than guide groove of escape groove.
Further, the lower surface of the baffle plate is provided with the boss for being used for wearing guide rod.
The present invention has the advantages that:
The present invention is installed on grain storehouse, and feed is connect by splicing case, and splicing case is fallen by open-and-close mechanism lower section, feed,
Splicing case leaves mouth, open-and-close mechanism closure, it is to avoid the accumulation of feed, using effect is good.
Brief description of the drawings:
Fig. 1 is structure chart of the present invention.
Fig. 2 is amplification assumption diagram of the present invention.
Fig. 3 is the structure chart of baffle plate in the present invention.
Fig. 4 is application structure schematic diagram of the invention.
Embodiment:
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the open-and-close mechanism in a kind of automatic feeding device of poultry of the invention, the open-and-close mechanism is set
In the discharge outlet of grain storehouse 2, including baffle plate 41, switchboard 42, guide rod 43, back-moving spring 44, pinch roller 45, pin 46 and floating
Spring 47, is provided with discharge opening 410 on baffle plate 41, and baffle plate 41 is fixed on the discharge outlet of grain storehouse 2, and switchboard 42 is located at baffle plate
The discharge opening 410 of baffle plate is simultaneously closed in 41 lower section, and the threaded one end of guide rod 43 is connected on switchboard 42, and the other end is plugged in
On baffle plate 41, back-moving spring 44 is sheathed on guide rod 43, and one end of back-moving spring 44 is connected on switchboard 42, and the other end is supported
It is connected on baffle plate 41.Pin 46 is plugged on switchboard 42, and the upper and lower ends of pin 46 are stretched in outside switchboard 42 respectively, is floated
Spring 47 is sheathed on pin 46, and the upper and lower ends of floating spring 47 are connected on pin 46 and switchboard 42 respectively, pinch roller
45 are rotatably connected on the upper end of pin 46, and pinch roller 45 is contacted at by floating spring 47 on the lower surface of baffle plate 41.
For ease of the installation of pin 46 and floating spring 47, installation slotted eye is provided with switchboard 42(Do not marked in figure),
Pin 46 is arranged in the installation slotted eye, and floating spring 47 is placed in the installation slotted eye, and floating spring 47 is sheathed on pin 46
On, it is fixedly connected with end cap 450 on the lower surface of switchboard 42, the lower end of pin 46 is through the connection end cap 450, floating spring
47 upper ends are connected on the side wall of pin 46, and lower end is connected on end cap 450.
Guide groove 411 and escape groove 412 are provided with the lower surface of baffle plate 41, guide groove 411 is mutually passed through with escape groove 412
It is logical, and depth of the depth more than guide groove 411 of escape groove 412, the rolling in guide groove 411 of pinch roller 45.
With reference to Fig. 4, several splicing casees 3 are mutually fixed on transmission chain 1 across a certain distance.Switchboard 42 is resetting
The lower section of baffle plate 41 is placed in the presence of spring 44 and the discharge opening 410 of baffle plate is closed, in the case where splicing case 3 is by switchboard 42
Fang Shi, splicing case 3 promotes pin 46, and switchboard 42 is moved right, so as to open discharge opening 410 so that in grain storehouse 2
Feed drop down onto in splicing case 3;When pinch roller 45 is moved in escape groove 412, because the depth of escape groove 412 is more than guide groove
411 depth, in the presence of floating spring 47, pin 46 is moved upwards, and now pin 46 departs from splicing case 3, is resetting bullet
In the presence of spring 44, switchboard 42 recoils to initial position and closes discharge opening 410.Treat that next splicing case 3 moves to grain storage
During 2 lower section of storehouse, said process is repeated.
When in use, the length of splicing case 3 is greater than the length of baffle plate 41, can cause in the springback process of switchboard 42,
Feed in discharge opening 410 is all dropped down onto in splicing case 3.
Guide groove 411 plays guide effect, can make it that the motion of pinch roller 45 is more steady.
The present invention is provided with the boss for being used for wearing guide rod 43 for ease of the installation of guide rod 43 on the lower surface of baffle plate 41
413。
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
