Under the driving of the driving component 32, after the weight detecting platform 31 rotates to a certain state, the controller 732 receives the instruction of the control panel 4 to supply power to the electromagnet 731, the electromagnet 731 adsorbs the positioning component 72, at this time, the electromagnet 731 adsorbs the positioning component 72 together, and at the same time, the positioning component 72 tightly abuts against the positioning ring 6, and at this time, the positioning component 72 fixes the positioning ring 6. Before the weight detecting table 31 needs to rotate, the controller 732 powers off the electromagnet 731 after receiving the instruction from the control panel 4, at this time, the electromagnet 731 loses the attraction force on the positioning member 72, the positioning member 72 loses the limitation on the positioning ring 6, and the rotating shaft 3112 and the weight detecting table 31 can rotate freely.

In order to prevent the positioning ring 6 from rubbing against the positioning ring 6 as much as possible during the rotation of the weight detecting table 31 after the electromagnet is powered off and the attraction force on the positioning member 72 is lost, the bottom wall of the sliding groove is fixedly connected with a thrust spring 7111, and one end of the sliding rod 722 extending into the sliding groove is fixedly connected with the thrust spring 7111. After the electromagnet 731 is de-energized, the sliding rod 722 pushes the positioning member 72 out of abutment with the positioning ring 6 under the force of the thrust spring 7111.

The peripheral cover of conveyer body 1 is equipped with pipeline 8, and pipeline 8 sets up to the shape with conveyer body 1 adaptation, and pipeline 8's one end is feed inlet 81, and pipeline 8's the other end is discharge gate 82, and discharge gate 82 communicates with the entry 21 of screening shell 2. The purpose of conveying pipe 8 setting lies in restricting the chicken on the conveyer body 1, avoids as far as possible the chicken on the conveyer body 1 to break away from conveyer body 1.

The equal fixed mounting in exit position department of screening shell both sides has infrared counter, and infrared counter can count the chicken through the export for the staff is more convenient high-efficient when the chicken of different weight is quantity.

The implementation principle of the conveyor with the weight screening function is as follows: when only conveying chicken, the staff places the chicken in conveyor body 1 by the material loading end 111 of conveyor body 1, the chicken is only conveyed to discharge end 121 department and falls onto weight detection platform 31 along with conveyor body 1, weight detection platform 31 detects the weight of chicken, and with signal transmission to control panel 4, the control surface is to controlling driving piece 32 corotation or reversal after carrying out the analysis according to the signal of weight detector 314 feedback, make the chicken of different weight only discharge through different export 22 via guide way 5, the counter can only count and feed back to control panel 4 to the chicken through export 22 in the exhaust process simultaneously.

A novel chicken flock elimination method by using a conveyor comprises the following steps:

s1, arranging a conveyor between the henhouse and the secondary epidemic prevention area in the secondary epidemic prevention area which is far away from the henhouse in the field area;

in the secondary epidemic prevention area of a remote place (generally 10-20 m) of the henhouse, the conveyor can adopt the conveyor with the weight screening function.

S2, arranging a chicken washing field outside the field area, arranging a turnover vehicle area and a social vehicle area in the chicken washing field, and arranging a conveyor between the turnover vehicle area and the social vehicle area;

the chicken washing ground is arranged at a place which is more than 500 meters away from the site, and the turnover vehicle area is separated from the social vehicle area by a physical isolation mode (such as a fence).

S3, arranging a turnover vehicle in the second-stage epidemic prevention area;

the turnaround vehicle may be provided in sections to facilitate alternate use in the panning process.

S4, conveying the chickens in the henhouse to a turnover vehicle through a conveyor;

in the process of conveying the chickens in the henhouse to the turnover vehicle through the conveying belt, the conveyor with the weight screening function can be used for screening the chickens.

And S5, transferring the chickens to a turnover vehicle area in the chicken washing yard through the turnover vehicles, conveying the chickens to the social vehicles in the social vehicle area through the conveyor in the chicken washing yard, and then conveying the chickens away through the social vehicles.

The implementation principle of the novel chicken flock elimination method by using the conveyor in the embodiment of the application is as follows: the method is characterized in that a conveyor with a weight screening function is adopted to convey the chickens to be eliminated in the henhouse to the transfer vehicle in the secondary epidemic prevention area from the inside of the henhouse, the chickens are screened in the process and then transferred to the chicken elimination field outside the field by the transfer vehicle, the chicken elimination field is separated from the inside and the outside, the social vehicles are isolated from the outside in a physical isolation mode, the transfer vehicle is not in contact with the social vehicles, and the chickens on the transfer vehicle are only transferred to the social vehicles through the conveyor belt to be transported away.

In the process, the influence of social vehicles on the environment of the henhouse is greatly reduced, the biological safety level is greatly improved, and the risk of contact propagation is reduced; meanwhile, the chickens in the henhouse are directly conveyed to the transfer vehicle through the conveyor, so that the transfer efficiency is greatly improved and the transfer cost is reduced compared with the traditional method that the chickens are transferred to the transfer vehicle from the henhouse through a trolley; compared with the prior art that the chickens are transported to the turnover vehicle by the small-sized cart in the henhouse, the method can also obviously reduce the death and culling rate. Because the chicken is only transported to the turnover vehicle by the trolley in the related art, the chicken on the vehicle is only overlapped, and the phenomena of killing the chicken and damaging the chicken can occur in the process. In the process of conveying the chickens in the henhouse to the transfer vehicle through the conveyor, the transfer vehicle is directly driven to the discharge end 121 of the conveyor belt, and then the chickens in the henhouse are sequentially conveyed to the transfer vehicle through the conveyor belt, so that the process can avoid the superposition of the chickens as much as possible, and the death rate is greatly reduced; the original 0.5% is reduced to the level of about 0.1%.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
