Description

Technical Field

[0001] This utility model relates to the field of livestock and poultry breeding equipment technology, specifically to a weighing device for weighing live livestock and poultry. Background Technology

[0002] In the production management of caged livestock and poultry, it is necessary to weigh the livestock and poultry regularly in order to optimize feeding programs and control breeding costs.

[0003] Taking broiler chickens as an example, the narrow openings and internal spaces of broiler cages make it inconvenient to place or remove existing weighing devices from the cages. The traditional method of weighing broiler chickens involves manually handling them and placing them on the weighing device. Manually handling chickens is physically demanding and can easily cause stress to the flock, which is detrimental to broiler growth. Furthermore, the unavoidable activities of live poultry during the weighing process (such as walking, shaking, and flapping wings) generate continuous vibrations, causing the weighing sensor readings to become unstable for extended periods, severely impacting weighing efficiency and the accuracy of the weighing data.

The output end of the drive structure is installed and connected to the drive screw 34, and the output drives the movement of the fixed axis of the drive screw 34.

[0023] Preferably, the drive structure includes a drive motor, an input shaft 37, a drive bevel gear 38, and a driven bevel gear 39; The input shaft 37 is rotatably connected to the base plate 12 via a bearing housing and a bearing. One end of the shaft is shaft-connected to the output end of the drive motor, and the other end is coaxially fixed with a drive bevel gear 38. The driven bevel gear 39 is coaxially fixed with the drive screw 34 and meshes with the drive bevel gear 38.

[0024] Preferably, it also includes a fixing rod and a fixing block; The two fixing rods are located between the top ends of a pair of first connecting rods and between the bottom ends of a pair of second connecting rods, and are connected and fixed to the lower base plate 31; the first connecting rods and the second connecting rods are hinged to the corresponding fixing rods and rotatably connected to the lower base plate 31. A support block is fixed on the lower fixed rod; the drive screw 34 passes through the support block and is rotatably connected to the support block via a bearing, so as to be rotatably supported on the lower base plate 31.

[0025] Preferably, the load-bearing platform 36 supports the load-bearing plate 13 through at least three protruding columns provided on its top. When the load-bearing platform 36 is a rectangular platform, four protruding columns are preferably provided and arranged at the four corners of the load-bearing platform 36 respectively. The pressure sensor is provided between the protruding columns and the load-bearing platform 36.

[0026] Preferably, it also includes a damping material layer; The damping material layer is formed of viscoelastic damping material covering the vibration damping holes and is arranged between the pressure sensor and the protrusion.

[0027] Preferably, the lower substrate 31 is supported and fixed to the top of the base plate 12 by the support rod 4.

[0028] Preferably, the bottom end of the support rod 4 is provided with a tenon structure, and the top of the base plate 12 is provided with a corresponding mortise structure. The tenon structure is fitted into the mortise structure to install and fix the support rod 4 and the base plate 12.

[0029] Preferably, the support structure is a support base fixed to the inner side wall of the cage 11. When the chicken cage 1 is a square chicken cage, four support bases are preferably provided, located at the four corners of the cage 11.

[0030] The following example, using the process of weighing broiler chickens, illustrates the working method of this application: The first step is to weigh the broiler chickens directly if they are already in the upper part of the cage 11; otherwise, place or drive the broiler chickens to be weighed into the upper part of the cage 11.

[0031] The second step is to fit the tenon structure at the bottom of the support rod 4 into the mortise structure at the top of the base plate 12, and then install and fix the support rod 4 and its upper lifting device 3 to the base plate 12.

[0032] Thirdly, the drive motor of the lifting device 3 is started, driving the input shaft 37 to rotate. The rotation of the input shaft 37 is transmitted to the drive screw 34 through the meshing drive bevel gear 38 and driven bevel gear 39, causing the drive screw 34 to rotate. Subsequently, the sliding block 32 slides along the sliding groove 361 under the limiting action of the sliding rod 33 and the sliding groove 361, causing the bottom ends of the first connecting rod and the second connecting rod to converge and move the load-bearing platform 36 upward until the load-bearing platform 36 lifts the load-bearing plate 13. At this time, the weight of the load-bearing plate 13 and the broiler chickens on it are borne by the load-bearing platform 36. The weight of the broiler chickens can be obtained based on the weight measured by the pressure sensor and the weight of the load-bearing plate 13 itself.

[0033] In the fourth step, the drive input shaft 37 of the lifting device 3 rotates in the opposite direction, causing the cross link 35 and the load-bearing platform 36 to reset. The load-bearing plate 13 falls and resets under the action of gravity, and is supported again by the support structure inside the cage 11, thus completing the weighing of the broiler chicken.

[0034] Fifth step, disassemble the tenon structure at the bottom of the support rod 4 from the mortise structure at the top of the base plate 12, and then remove the support rod 4 and the lifting device 3 from between the load-bearing plate 13 and the base plate 12 for future use.
