The growth and development conditions of the chicken flock can be known by detecting the weight of the chicken flock, and the method is also an important basis for determining the feeding amount when raising the bred chickens in a limited manner. In the raising process of broiler chickens, the average weight needs to be measured periodically so as to adjust raising management measures in time, or broiler chickens which grow slowly are selected from chicken flocks to be fed in a focused mode, so that the feeding level and the feeding amount are ensured to reach the expected purposes, and the average weight and uniformity of the chicken flocks are improved.

When the base, the turntable frame, the fixed peripheral plate 410, the rotating peripheral plate 510 and other structures are assembled together, two limiting areas (marked as limiting area A610 and limiting area B620) with left side walls, right side walls, top walls, bottom walls and inner side walls are enclosed between the baffle 320, the annular bottom plate 110 and the annular top plate 120 at the end parts of the two arc-shaped plates 310 forming the turntable frame, and one side without the outer side walls can be used for chickens to pass through to enter the limiting areas.

The working principle of the application will be described in detail as follows:

(1) In the process of rotating the turntable frame, the limiting area also rotates along with the rotation, when the limiting area A610 rotates to the inlet area, chickens can enter the limiting area A610 through the inlet area, and as the inlet area corresponds to the installation position of the electronic scale 200, the chickens are just positioned on the electronic scale 200 when entering the limiting area A610 from the inlet area, the system measures and records the weight of the chickens, and judges the preset weight range of the chickens, as shown in the positions (a 1) and (a 2) in fig. 15 and 16, the mark (1) in the limiting area A610 in fig. 15 and 16 indicates that the chickens enter, and the mark (0) indicates that the chickens do not enter;

(2) The limiting area a 610 will continue to rotate with the turntable rack, and the chickens will move under the turntable rack and move on the annular bottom plate 110 and leave the electronic scale 200, and when the limiting area a 610 moves within the area covered by the fixed peripheral plate 410, the chickens are blocked by the fixed peripheral plate 410 and will remain in the limiting area a 610, as shown in the positions (b 1) in fig. 15 and (b 2) in fig. 16;

during the movement within the area covered by the stationary peripheral plate 410, the system will determine the action of rotating the peripheral plate 510 based on the weight range of the chicken obtained in step (1);

specifically, in one embodiment, if the chicken weight is in the range of (0, x), it is determined that the chicken weight is too low, and it is desired to move the chicken out of the restriction area A610 from the second exit area and into the second sorted area, where the device will issue a command to control the peripheral board to be located in close proximity to the stationary peripheral board 410;

when the weight of the broiler breeder is in the (x, y) range, determining that the weight of the broiler breeder is appropriate, the broiler breeder needs to leave the restriction area a 610 from the first exit area and enter the first sorted area, and the device will issue a command to place the rotating peripheral plate 510 at a position spaced by pi/2 radians from the fixed peripheral plate 410;

(3) The restricted area a 610 continues to rotate away from the fixed peripheral plate 410 as the turret frame, during which the rotating peripheral plate 510 will move in accordance with the command information;

specifically, when the weight of the broiler breeder is in the range of (0, x), the rotary peripheral plate 510 is controlled to rotate to a position close to the fixed peripheral plate 410, if the rotary peripheral plate 510 is just positioned close to the fixed peripheral plate 410, the rotary peripheral plate 510 is kept stationary, as shown in the position (c 2) in fig. 16, the first outlet area is blocked, and the second outlet area is opened;

when the weight of the broiler breeder is in the (x, y) range, the rotary peripheral plate 510 is controlled to rotate to a position spaced apart from the fixed peripheral plate 410 by pi/2 radians, if the rotary peripheral plate 510 is just positioned at a position spaced apart from the fixed peripheral plate 410 by pi/2 radians, the rotary peripheral plate is kept stationary, and the rotary peripheral plate is positioned at the position shown in (c 1) in fig. 15, so that the first outlet area is opened and the second outlet area is blocked, and thus when the limiting area A610 rotates to the first outlet area position, the broiler breeder can leave from the limiting area A610 to enter the first sorted area, and the limiting area A610 becomes a vacancy (0); the turntable frame continues to rotate, the limiting area B620 reaches the position of the inlet area in the rotating process, as shown in the position (d 1) in fig. 15, at this time, the next broiler breeder is guided to enter the limiting area B620, the steps are repeated, and the broiler breeder is sorted into the first sorted area or the second sorted area according to the weight of the broiler breeder.

The steps are repeated until all the broiler breeder chickens in the area to be weighed are guided into the weight measuring device provided by the application for sorting.

Further, the device for measuring and separating the weight of the broiler breeder provided by the application further comprises a first driving mechanism for driving the turntable frame to rotate around the axis of the turntable frame, and a second driving mechanism for driving the rotary peripheral plate 510 to rotate around the axis of the rotary peripheral plate.

the top of the two arc plates 310 are connected with the first rotating sleeve 340 through the first connecting rod 360.

In the above structure, the top of the arc-shaped plate 310 is connected with the first rotating sleeve 340 through the first connecting rod 360, and the first motor 350 drives the first rotating sleeve 340 to rotate around the fixed shaft 330, which drives the whole turret frame to rotate. As shown in fig. 7, the number of the first connecting rods 360 is four, and the first connecting rods 360 are distributed in an annular array along the circumferential direction, and the specific number of the first connecting rods 360 is determined according to the material and the stress characteristics during the actual manufacturing of the device. In addition, a reinforcing rod is typically provided between the first rotating sleeve 340 and the first connecting rod 360.

Further, a cylindrical gear 370 is fixedly sleeved on the first rotary sleeve 33, and the cylindrical gear 370 is meshed with the cylindrical gear 370 on the output shaft of the first motor 350 to drive the first rotary sleeve 340 to rotate. Further, the first rotating sleeve 340 is rotatably fitted over the fixed shaft 330 by a pair of tapered roller bearings 341, and can receive the load transmitted from the turntable.

the top of the rotating peripheral plate 510 is connected to the second rotating sleeve 520 by a second attachment rod 540.

In the above structure, the top of the rotating peripheral plate 510 is connected to the second rotating sleeve 520 through the second connection rod 540, and the second motor 530 drives the second rotating sleeve 520 to rotate around the fixed shaft 330, which drives the rotating peripheral plate 510 to rotate. As shown in fig. 10, the number of the second attachment rods 540 is two, and the specific number of the second attachment rods 540 is determined according to the material and the stress characteristics during the actual manufacturing of the device.

Further, a bevel gear 550 is coaxially fixed to the second rotating sleeve 520, and the bevel gear 550 is engaged with the bevel gear 550 on the output shaft of the second motor 530 to drive the second rotating sleeve 520 to rotate. Further, the second rotating sleeve 520 is rotatably sleeved on the fixed shaft 330 through the thrust ball bearing 521.

Considering that the load transferred to the second rotating sleeve 520 by the rotating peripheral plate 510 is biased to one side of the second rotating sleeve 520, there is a unbalanced load phenomenon, in another embodiment, the bottom of the rotating peripheral plate 510 is provided with a plurality of rollers 511, and referring to fig. 11, the axial direction of the rollers 511 is arranged along the radial direction of the annular bottom plate 110, the outer circumference of the annular bottom plate 110 is provided with an arc-shaped guide rail 512, and the rollers 511 can roll along the arc-shaped guide rail 512; the arcuate rail 512 is adjacent to the fixed peripheral plate 410 in the circumferential direction of the annular base plate 110, and the arcuate rail 512 spans an arc of pi in the circumferential direction of the annular base plate 110.

When the weight measuring device provided by the application is used for weighing and separating the broiler breeder, the device is placed in a flat raising chicken house, the broiler breeder in the chicken house is enclosed by using a fence, namely, the broiler breeder is enclosed in a region to be weighed, an elongated guide channel is enclosed by the fence, and an inlet region of the device is connected with the region to be weighed by the elongated guide channel; and then the first sorted area and the second sorted area are surrounded by the fence and are respectively connected with the first outlet area and the second outlet area of the device so as to receive the meat chickens sorted according to the weight.

During weighing, the broiler breeder in the area to be weighed is slowly driven into the slender guide channel and approaches the entrance area. The confinement region is moved to the entry region and the foremost broiler breeder is driven into the confinement region using a cage or other object. The rotating speed of the turntable frame is set reasonably, so that the condition that the meat chickens enter or leave the limiting area due to too high rotating speed is avoided, the limiting area is not too small, and the condition that the meat chickens enter or leave the limiting area in the rotating process of the turntable frame is guaranteed.

In order to ensure that the broiler breeder can smoothly walk from the limiting area to the first separated area or the first separated area and the second separated area, feed or green vegetables for the broiler breeder to feed are placed in the limiting area, and the broiler breeder is attracted to leave the limiting area. The number of the meat chickens which are not up to standard in weight in one henhouse is usually smaller than the number of the meat chickens which are up to standard, so that the fences of the area to be weighed and the first separated area can be adjusted at any time in the weighing process, and the meat chickens in the first separated area have sufficient activity space. The meat chickens selected in the second separated area are concentrated; the other chicken house is specially fed, so that the weight of the broiler breeder can reach the standard when the broiler breeder goes out of the house.

The features of the device according to the application will be more clearly illustrated by the following examples of implementation.

The test group is weighed by adopting the device of the application, and the comparison group is weighed by adopting the traditional grabbing.

1000 hens of 8 weeks old, which were routinely raised in the henhouse, were randomly divided into 2 groups of 500, each, and were designated as test and control groups, respectively. The test group adopts the weighing device of the application, the control group adopts the traditional grabbing weighing method, both groups are routinely fed until the end of 16 weekends, 9 weeks are taken as the end of each week, the weighing is carried out at the end of each week, the feeding is carried out for 12 hours before the weighing, and 50 groups are weighed from 8 hours in the morning. And (3) separating the meat breeder chickens with the body weight not reaching the standard from the chicken flock when weighing each time, and leaving the remaining meat breeder chickens in the chicken house.

When weighing on 8 weekends, the test group and the control group adopt the device and the traditional grabbing and weighing method for weighing at the same time, and the results are shown in Table 1; the weighing results per weekend of 10-16 weeks are shown in Table 2.

Note that: data are expressed as mean ± standard error.

As can be seen from Table 1, the device and the traditional grabbing and weighing method are adopted to sample and weigh the groups, the weight difference is not obvious (P is more than 0.05), and the device is proved to have high accuracy due to normal sampling errors.

Table 2 comparison of weight values of broiler breeder chickens in control and experimental groups (unit: g)

Note that: data are expressed as mean ± standard error.

As can be seen from table 2, the weight difference between the two groups of broiler breeders was insignificant at the early 10-week-old stage (P > 0.05), whereas after 3 weeks (11 weeks start), the weight of the control group was significantly lower than that of the test group (P < 0.5) due to the stress and separate feeding of the broiler breeders by the conventional grabbing and weighing method.

The overall conclusion is that the weight of the broiler breeder is weighed by adopting the device, the obtained data is not obviously different from the traditional grabbing and weighing method, the device reduces the stress of the broiler breeder, and the average daily gain of the broiler breeder can be obviously increased.
