Description

Technical Field

[0001] This utility model relates to the field of respiratory pyrography technology, and in particular to a manure collection device for measuring the respiratory pyrography of laying hens. Background Technology

[0002] Net energy (NE) systems, by considering the heat gain (HI) of different types of diets, are more accurate in assessing the effective energy value of feed ingredients and the energy and nutritional requirements of poultry. Therefore, accurately assessing the net energy value of laying hen feed ingredients is of great significance for the efficient utilization of feed ingredients and the sustainable development of the laying hen industry. A novel 12-chamber parallel open-loop respiration calorimeter for poultry is used to assess the net energy value of laying hen feed ingredients. This device mainly consists of a gas analyzer, a metabolic chamber, a gas path system, a vortex blower, and other supporting equipment. The metabolic chamber frame was made of square steel and sealed with a glass lid. Water was then poured into the grooves around the chamber to create a sealed environment. During the experiment, the lid needed to be opened daily to collect the laying hen droppings from the chamber using a shovel. However, during the process of closing and opening the lid, surface tension of the water (when the lid is placed in water, the surface tension temporarily prevents water from entering; when it is quickly removed from the water, the surface tension is suddenly released, causing the water to be squeezed out, resulting in splashing) and changes in air pressure (when the lid is placed in water, the internal air is compressed; when it is removed, the compressed air expands rapidly, causing a change in internal pressure, thus squeezing out the water) caused problems. This process frequently causes water to splash into the chicken droppings in the metabolic chamber, mixing the droppings with the water. This makes it difficult to remove feathers and dander, increasing the difficulty and time required for collection. The mixture of chicken droppings and water also accelerates microbial fermentation, decomposing organic matter in the droppings and producing other impurities, gases, and heat. This hinders subsequent drying of the droppings and affects the accuracy of subsequent testing of relevant indicators. Furthermore, because the droppings tray in the metabolic chamber is horizontal, researchers need to bend over to collect the droppings. Excessive bending at an angle and prolonged bending can cause lower back pain. Therefore, we designed a droppings collection device based on hen respiration thermometry to address these technical problems. Utility Model Content

The base contains a hen cage placement area and a manure collection area. The manure collection plate is inclinedly positioned in the hen cage placement area, with its lower end connected to the manure collection area. Upward-extending, waterproof baffles are fixed to the baffles on both sides of the manure collection plate. By setting the manure collection plate at an incline and connecting its lower end to the manure collection area, it is convenient for researchers to scrape the chicken manure from the collection plate to the collection area for unified collection, reducing back fatigue caused by bending over to collect manure and improving the convenience and efficiency of manure collection. When the glass cover of the respiration calorimetry device is opened, water splashing out from the groove of the metabolic chamber due to surface tension is blocked by the raised waterproof baffles of this device, preventing the mixing of manure and water from increasing collection difficulty and avoiding microbial fermentation that could affect the accuracy of manure sample testing, thus improving the accuracy of manure sample testing.

[0017] Furthermore, the waterproof panel and baffle are integrated into one structure, and the base and baffle are also integrated into one structure, which facilitates manufacturing and improves production efficiency.

[0018] Furthermore, the base, baffle, and manure collection plate are all made of PVC, which is wear-resistant and corrosion-resistant, thus extending their service life. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The purpose of this invention is to provide a manure collection device for measuring the respiration heat of laying hens, in order to solve the problems existing in the prior art, improve the convenience of manure collection and the accuracy of manure sample detection, reduce the labor intensity of experimental personnel, and improve experimental efficiency.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1-4 As shown, this embodiment provides a manure collection device for measuring the respiration temperature of laying hens, including a base 1 and a manure collection plate 2. The base 1 has an upwardly extending baffle 3 on its edge. The base 1 has a laying hen cage placement area 4 and a manure collection area 5 inside. The manure collection plate 2 is inclinedly set in the laying hen cage placement area 4. The lower end of the manure collection plate 2 is connected to the manure collection area 5. The baffles 3 on both sides of the manure collection plate 2 are fixedly provided with upwardly extending waterproof plates 6.

[0029] In use, the entire device is placed in the metabolic chamber of a 12-chamber parallel poultry open reflux respiratory calorimeter. The laying hen cages are then placed in the laying hen cage placement area 4. During respiratory calorimetry testing, hen droppings fall onto the manure collection plate 2. The lower edge of the manure collection plate 2 connects to the manure collection area 5, allowing a scraper to easily scrape the droppings from the plate onto the collection area 5 (i.e., the bottom plate of the base 1 corresponding to the collection area 5) for centralized collection. The manure collection plate 2 is tilted to reduce back fatigue caused by bending over to collect droppings, improving the convenience of manure collection and increasing experimental efficiency. When the glass cover of the respiratory calorimeter is opened, water splashes out from the groove of the metabolic chamber due to surface tension. This water is blocked by the device's raised waterproof plate 6, preventing the mixing of manure and water from increasing collection difficulty and avoiding microbial fermentation that could affect the accuracy of manure sample testing. This provides reliable support for the accurate assessment of the net energy value of laying hen feed ingredients.

[0030] In this embodiment, the heightened waterproof plate 6 and the baffle 3 are an integral structure, which facilitates manufacturing.

[0031] In this embodiment, the base 1 and the baffle 3 are an integral structure, which facilitates manufacturing and improves the overall structural strength.

[0032] In this embodiment, the manure collection plate 2 is a convex-shaped plate, and the laying hen cage placement area 4 is a convex-shaped placement area corresponding to the convex-shaped plate.

[0033] In this embodiment, the baffles 3 on both sides of the base 1, which is perpendicular to the raised waterproof plate 6, are provided with gripping openings 7. The gripping openings 7 are rectangular openings, which are convenient for gripping so that the device can be placed in the respiratory calorimetry and metabolic chamber, and also convenient for removing the device for cleaning.

[0034] In this embodiment, the base 1, baffle 3, and manure collection plate 2 are all made of PVC, which is wear-resistant and corrosion-resistant, thus improving their service life.

[0035] In this embodiment, the inclination angle of the manure collection plate 2 relative to the base 1 is 5°-15°, preferably 10°. In use, other different inclination angles can also be set according to actual conditions.

[0036] In this embodiment, the base 1, baffle 3, heightened waterproof plate 6, and manure collection plate 2 are all of equal thickness and 0.5cm, which facilitates their manufacture.

[0037] To further illustrate the application value of this device, a comparison was made between its efficiency and that of a traditional square manure collection tray for manure collection. The traditional square manure collection tray achieved a collection efficiency of 6 minutes per cage, while the device achieved 3 minutes per bird. This device improves sampling efficiency by approximately 100%, saving time, reducing physical exertion and lower back strain. Furthermore, the water splashed during opening and closing of the lid is blocked by raised waterproof plates on both sides, ensuring the freshness and integrity of the collected chicken manure and guaranteeing experimental accuracy. Therefore, the sampling efficiency of this device is significantly high, and it shows promising application prospects in studies involving laying hens for animal nutrition and metabolism experiments and the evaluation of the nutritional value of feed ingredients.
