Embodiment Construction

[0032] The specific structure of the present invention will be further described below with reference to the drawings and embodiments.

[0033] Such as figure 1 with figure 2 As shown, the test device is composed of a test bench base and a measuring device. Among them, the base of the test bench is used to suspend the test cage, and the measuring device is used to statically read the pre-tightening force of the reinforcing rib, the initial tension of the suspension beam on the bottom net and the reinforcing rib under the action of the load, the stress value of the suspension beam, and the deformation of the bottom net.

[0034] Test bench base such as figure 1 with image 3 As shown, the front cross beam 18 and the rear cross beam 1 respectively pass through 5 supporting legs 12 of equal length from left to right, and each supporting leg 12 corresponds to a group in front and rear, a total of 5 groups; the two supporting legs 12 in the leftmost group The left support plate 11 is f...

Abstract

The invention belongs to the field of animal husbandry mechanical performance test and particularly relates to a laying hen welfare cage bottom net load test device and a method thereof. Laying hen welfare cage bottom net deformation amount and stress values of a strengthening rib and a suspension beam are measured so as to provide the basis for the design of the whole structure of a laying hen welfare cage with different bottom net structure parameters. The test device comprises a test stand base and a measuring device, wherein the test stand base is used for suspending a test cage, and the measuring device is used for statically reading pretightening force of the strengthening rib, initial pretension exerted by the suspension beam to the bottom net, the stress values of the strengthening rib and the suspension beam under loading action and the bottom net deformation amount. According to the device, the length and width of a rectangular outer frame for installing the bottom net, the pretightening force of the strengthening rib and egg rolling angle can be adjusted according to bottom nets with different areas, netting wire diameters and mesh sizes, and a tension sensor and a displacement meter with high accuracy can be matched. The device is well in butt joint with a laying hen welfare breeding device, and the obtained data can be used for guiding evaluating, developing and popularizing of relevant cages.

Description

Technical field [0001] The invention belongs to the field of animal husbandry mechanical performance detection, and in particular relates to a device and method for bottom net load test of layer welfare cages. Background technique [0002] With the improvement of the degree of intensification of the poultry industry in our country, how to ensure the welfare of layer hens and produce safe eggs in the process of laying hen cages is the current research hotspot of layer breeding industry. With such concerns about animal welfare, the development and promotion of layer welfare cages is the development trend of layer cages in the future. [0003] The design of the bottom net of the layer cage differs depending on the breeding mode, age, and variety. Its structural parameters include: bottom net area, mesh wire diameter, rolling angle, and mesh density. The bottom net of traditional layer cage adopts intermediate installation nets. However, the welfare type chicken cage has a large botto...
