Detailed Description

In the process of breeding a large number of livestock, the screening of livestock individuals is very necessary. The livestock individual screening not only considers the size (weight) of an individual, but also considers the disease condition and the infectious disease condition of an individual sheep, and carries out targeted feeding and treatment and the like aiming at different sorted groups. The following describes a specific application form of the automatic livestock individual sorting system through the attached drawings.

According to a planning idea, an automatic weight measuring system of livestock is built in one period, and the livestock are classified into qualified livestock and unqualified livestock according to the daily gain of the livestock.

And designing a scheme for the system according to the construction target. The system is divided into three layers from a functional logic layer, namely a measuring system, a screening system and an execution system.

The measurement system needs to have an RFID tag identification function to identify each cow; the weight measurement system needs to measure the weight index of the cattle.

The screening system judges the quality of the bred cattle according to the condition of the periodic weight change of each cattle.

And the execution system correspondingly executes the opening/closing of the barrier gate according to the judgment result.

The logic diagram of the system is shown in figure 1, and the system composition is shown in figure 2.

In fig. 2, the automatic sorting system for the livestock individuals is sequentially provided with an inlet channel 1, an inlet gate 2, an electronic platform scale 3, an outlet gate 10, a linkage driving mechanism 7 and a linkage door 6 from front to back, a standard weight channel 4 and a non-standard weight channel 5 are respectively arranged on two sides of the linkage door 6, and an auxiliary conjoined lock 8 arranged on the rear side of the linkage door 6 can control locking of the linkage door 6.

The inlet channel 1 is in a conical convergent shape, the proximal end is wide, the distal end is narrow, the narrow end extends forwards in parallel to form a weighing channel, and an electronic platform scale is arranged in the weighing channel.

Two curved flexible bodies 34 (rubber or waste wheel pieces) are fixed on the two inner side walls of the inlet passage 1 respectively to prevent the possibility of the smaller bodies entering in parallel.

The weighing channel is a straight channel, namely two side walls are of a parallel vertical surface structure, and data of the electronic platform scale 3 are arranged above the weighing channel and are connected with the background database through data lines. Display equipment can be additionally arranged at the periphery of the system and used for displaying the weight of the corresponding cow in real time. Because each cow establishes identity information in advance, an RFID tag is fixed on a cow ear, and a corresponding database unit is established for each cow in a system background, the RFID radio frequency identification utilizes a non-contact automatic identification technology, automatically identifies a target object and obtains related data through radio frequency signals, the identification work does not need manual intervention, and the system can work in various severe environments. The identity of each cow can be identified by wearing the device for each cow, and the built-in program can identify and trigger program operation according to the ID.

After the RFID identification probe 24 and/or the image acquisition device 26 are/is respectively arranged on the side surface of the system inlet channel shown in fig. 1, the PLC control system detects the weight data information of the target cow individual through the RFID identification probe 24, opens the corresponding database unit to record the weight data, and acquires the image information of the target cow individual through the image acquisition device 26 and stores the image information in the corresponding database unit.

The inlet gate 2 and the outlet gate 10 are respectively positioned at the front end and the rear end of the electronic platform scale 3 and are opened and closed alternately. When the RFID identification probe 24 detects that the target cattle individual passes through and the electronic platform scale 3 is weighed that no cattle individual exists, the entrance gate 2 is opened. After the target cattle enters the electronic platform scale 3, the entrance gate 2 is always closed to prevent the rear cattle from entering the weight data affecting the target cattle. When the weight data of the target cattle is unstable, the outlet gate 10 positioned at the rear side is still in a closed state, and the outlet gate 10 is not opened until the data is stable and accurate.

It can be seen that the weighing channel ends in a divergent configuration, with both sides leading to a standard weight channel 4 and a non-standard weight channel 5, respectively.

The two ends of the buried rotary rod 18 in the caulking groove are respectively sleeved with a shaft sleeve, and the shaft sleeves are fixed in the caulking groove and used for restraining the rotary rod 18 to keep the stability of the rotary rod.

In addition, a press-touch switch 23 is installed on the side surface of the limit stop 9, when any linkage door 6 is closed and touches the corresponding press-touch switch 23, the PLC control system receives the touch signal and controls the electric push rod to extend or retract, so that the buried rotating rod 18 rotates to drive the stop rods 19 on the two sides to be vertical and higher than the ground, and the buried rotating rod is used for supporting and blocking the linkage door 6 on the other side to achieve the state that the linkage door 6 is locked. It is necessary that the linked gate 6 be locked, otherwise the target cow may rush into another lane causing confusion in selection.

Further, controllable latch mechanisms are installed on the ground at the front side of the inlet gate 2 and the rear side of the outlet gate 10, respectively, to improve the closing strength of the inlet gate 2 and the outlet gate 10, preventing cattle from hitting the gates and causing damage.
