Description

TECHNICAL FIELD

[0001] The utility model relates to poultry weighing technical field, concretely relates to a poultry weight scale. BACKGROUND

[0002] Weighing poultry is very important for each link of poultry breeding, plays an irreplaceable role in guaranteeing poultry health and improving breeding efficiency, and selects the best marketing time according to the weight of poultry. If the weight of poultry reaches the standard, timely marketing can maximize profits.

[0003] The existing weighing equipment often causes poultry to shake due to activity during weighing, so that the weighing data is inaccurate. At the same time, poultry randomly walk and flutter during weighing, which causes great fluctuation of weighing value, so that accurate weight cannot be obtained. At the same time, the existing weighing equipment directly contacts poultry with weighing equipment, and the excrement, feathers and bacteria carried by poultry on the body are easy to contaminate the weighing equipment. This not only shortens the service life of the equipment and affects its long-term stable operation, but also may cause cross infection of bacteria among different poultry groups, which is not conducive to healthy breeding of poultry.

[0004] The traditional method needs to manually move poultry one by one to the weighing equipment for weighing, and then manually judge whether the weight is qualified and classify, which consumes a lot of manpower and time, and the weighing efficiency is low. The poultry with qualified and unqualified weight cannot be quickly and accurately diverted, which affects the smoothness of the overall breeding process.

[0005] Therefore, the utility model designs a poultry weight scale to solve the above problems. UTILITY MODEL CONTENT

[0006] The utility model solves the technical problem of overcoming the above-mentioned shortcomings of the prior art and providing a poultry weight scale.

[0007] The technical scheme adopted to solve the above technical problems is:

[0008] A poultry weight scale, comprising a mounting assembly, a weighing assembly for weighing is installed on the mounting assembly, a lifting conveying assembly that can be lifted is installed on the mounting assembly, a rejection assembly for rejecting poultry with unqualified weight is installed on the mounting assembly, a placing box assembly for placing poultry and limiting the activity of poultry is installed on the mounting assembly, a second conveying belt, a third conveying belt and a fourth conveying belt for transporting the placing box assembly are installed on the mounting assembly.

[0009] The placement box assembly includes a placement box body, a cover plate, a rectangular groove, a first mounting bracket, a limiting rod, and a locking device. The rear end of the cover plate is hinged to the upper rear side of the placement box body. A rectangular groove is formed at the front end of the upper end of the cover plate. Two sets of the first mounting bracket and the limiting rod are arranged left and right, respectively, on the left and right sides of the front end of the cover plate. The rear end face of the first mounting bracket is fixedly connected to the front end face of the cover plate. The two sets of the limiting rods are fixedly installed on the inner side walls of the two sets of first mounting brackets. Two sets of the locking device are arranged left and right, and the locking device is connected to the placement box body and the limiting rod. Ventilation grooves are formed on the rear side of the upper end face of the cover plate on the four side walls of the placement box body.

[0010] The above technical solution restricts poultry movement by placing them in a placement box assembly and locking it in place, preventing inaccurate weighing. Weighing the poultry in the placement box assembly also avoids direct contact between the poultry and the weighing equipment, reducing the risk of cross-infection. This not only promotes long-term stable operation of the equipment but also maintains a good working environment. The placement box assembly is then transported to the weighing assembly via a lifting conveyor assembly and a second conveyor belt. When the placement box assembly reaches the weighing assembly, the lifting conveyor assembly descends to allow the poultry to rest. The weight of the placement box component is completely transferred to the weighing component, avoiding weighing errors caused by some weight being distributed on the lifting and conveying component. When the poultry weight is qualified, the lifting and conveying component will rise and transport the placement box component with qualified poultry weight to the third conveyor belt for transportation. When the poultry weight is unqualified, the rejection component will remove the unqualified placement box component and transport it to the fourth conveyor belt for transportation, realizing efficient weighing and classification of poultry. The rectangular groove on the cover plate can place the poultry's head on the outside, making the poultry breathe more smoothly and reducing the stress response caused by the confined space and obstructed breathing.
