Description

Technical Field

[0001] The utility model relates to the technical field of cattle-raising equipment, in particular to a cowshed with a spray cooling function. Background Technique

[0002] Since the new century, with the development of the economic society and the improvement of the living standard, people's consumption demand has changed from quantity-based to quality-based. Beef with high protein content, low fat content and more delicious taste is increasingly favored by consumers. There are rich resources of hilly grasslands and slopes in the south, and the growing period of forage grass is longer than that in the north, which provides good material basis and conditions for the beef cattle breeding industry.

[0003] However, in the southern subtropical region, the summer lasts for up to 4 months, the extreme temperature is above 40 °C, and it is humid and rainy. Moreover, beef cattle are homeothermic animals without active sweat glands. Therefore, under the high temperature and high humidity conditions in the south, heat stress reactions are extremely likely to occur. Heat stress is the sum of non-specific response reactions when humans or animals are stimulated by excessive temperatures beyond their body temperature regulation ability. Currently, the temperature-humidity index (THI) is often used to judge whether animals are in a heat stress state. The THI threshold for beef cattle to have heat stress is 74. When THI ≤ 74, beef cattle have no heat stress; when 75 ≤ THI ≤ 78, beef cattle are in mild heat stress; when 79 ≤ THI ≤ 83, beef cattle are in moderate heat stress; when THI > 83, beef cattle are in severe heat stress.

[0004] The existing cowsheds on the market usually use two methods, namely fans and sprays, to cool the beef cattle shed to prevent heat stress reactions of beef cattle from affecting the fattening of cattle. However, the cooling fans or spray mechanisms in the existing cowsheds are not convenient for automatically controlling the start and stop of the fans and spray mechanisms according to the temperature-humidity index in the cowshed. They often need to be manually turned on by the breeding staff, which may cause irreparable damage due to the negligence of the breeding staff. Moreover, the nozzles in the existing cowshed spray mechanisms lack protective structures. When the spray mechanism is not needed, the nozzles cannot be protected. The nozzles exposed for a long time are easy to adsorb dust and cause blockage of the water spray holes, affecting the normal use of the subsequent spray mechanism and reducing the service life of the spray mechanism.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to Figures 1-6 , a cowshed with a spray cooling function provided by the present utility model includes a cowshed body 1. A passage is provided at the middle position of the inner bottom end of the cowshed body 1. A plurality of breeding pens 2 distributed in a linear array are provided on both sides of the passage inside the cowshed body 1. A support crossbeam 3 is fixedly connected to the inner wall of the cowshed body 1. An air-cooling mechanism is provided above each breeding pen 2 at the top of the support crossbeam 3. A spray cooling mechanism is further provided above the air-cooling mechanism inside the cowshed body 1. A temperature and humidity sensor 4 and a PLC controller 5 are also provided inside the cowshed body 1. The temperature and humidity sensor 4 is suspended inside the cowshed body 1 by a suspension rope, and the PLC controller 5 is fixedly installed on the inner wall of the cowshed body 1. A protection mechanism is provided below the spray cooling mechanism inside the cowshed body 1.

[0027] By the combined use of the PLC controller 5, the temperature and humidity sensor 4, the air-cooling mechanism and the spray cooling mechanism, when the temperature-humidity index of the internal environment of the cowshed body 1 is at different values, the air-cooling mechanism and the spray cooling mechanism can be automatically opened and closed in a timely manner without manual operation, realizing the intelligent breeding of the cowshed.

[0028] The air-cooling mechanism includes a driving motor 6 fixedly installed on the top of the support crossbeam 3. The driving motor 6 uses an existing waterproof motor or a waterproof cover is installed outside the motor (not shown in the figure). The output end of the driving motor 6 is fixedly connected to a rotating rod 7, and the bottom end of the rotating rod 7 is fixedly connected to a fan blade 8.

[0029] The spray cooling mechanism includes a water supply pipe 9. One end of the water supply pipe 9 is fixedly communicated with a water delivery pipe 22. The other end of the water delivery pipe 22 penetrates through the cowshed body 1 and is fixedly communicated with a spray pipe 10. A nozzle 11 is fixedly communicated below the spray pipe 10. A water spraying hole 12 is provided at the bottom end of the nozzle 11. An electromagnetic valve 13 is provided on the water supply pipe 9. The spray pipe 10 is located above the air-cooling mechanism.

[0030] The protection mechanism includes two support rods 14, and the two support rods 14 are respectively and fixedly installed on both sides of the inner wall of the cattle shed body 1. The outer surfaces of the two support rods 14 are both movably sleeved with sliding rings 15. A protection plate 16 is fixedly connected between the bottoms of the two sliding rings 15. A plurality of through holes 17 distributed in a linear array are opened at the bottom of the protection plate 16, and the size of the through holes 17 is adaptively set to the size of the spray heads 11;

[0031] When the spray cooling mechanism is not required to spray and cool the internal environment of the cattle shed body 1, the electric telescopic rod 18 contracts to drive the protection plate 16 to move until the through holes 17 on the protection plate 16 are in an interleaved state with the spray heads 11, so as to use the protection plate 16 to cover and protect the bottom ends of the spray heads 11, avoid the blockage of the water spray holes 12 caused by the long-term exposure of the spray heads 11, play a protective role for the spray heads 11, is beneficial to the subsequent normal use of the spray cooling mechanism, and improves the service life of the spray cooling mechanism.

[0032] One side of the inner wall of the cattle shed body 1 is fixedly connected with an electric telescopic rod 18, the telescopic end of the electric telescopic rod 18 is fixedly connected with a connecting block 19, and the top of the connecting block 19 is fixedly connected with the bottom of the protection plate 16.

[0033] Both sides of the cattle shed body 1 are provided with shed doors 20, and a plurality of ventilation windows 21 are also opened on the cattle shed body 1.

[0034] When using this cattle shed to raise beef cattle, through the temperature and humidity sensors 4 arranged inside the cattle shed body 1, the temperature and humidity of the internal environment of the cattle shed body 1 can be monitored, and the monitored output end is transmitted to the PLC controller 5. The PLC controller 5 uses its own central processing unit to receive the temperature and humidity data, and calculates the temperature-humidity index through the calculation formula: THI = 0.81×T + RH×(T - 14.40) + 46.40 [THI is the temperature-humidity index; T is the ambient temperature; RH is the relative humidity]. The THI threshold is 74. When THI≤74, the beef cattle have no heat stress; when 75≤THI≤78, the beef cattle are in mild heat stress; when 79≤THI≤83, the beef cattle are in moderate heat stress; when THI>83, the beef cattle are in severe heat stress;

[0035] When the calculated THI≤74, the beef cattle have no heat stress, and at this time, there is no need to turn on the air-cooling cooling mechanism and the spray cooling mechanism;

[0036] When the calculated humidity index is in the range of 75≤THI≤78, the beef cattle are in mild heat stress. At this time, the PLC controller 5 turns on the drive motor 6 in the air-cooling cooling mechanism. The output end of the drive motor 6 rotates, drives the rotating rod 7 to rotate, and further drives the fan blades 8 to rotate synchronously to air-cool the beef cattle raised in the breeding pen 2;

[0037] When the calculated humidity index is in the range of 79 ≤ THI ≤ 83, the beef cattle are in moderate heat stress. At this time, on the basis of turning on the air-cooling and cooling mechanism, the solenoid valve 13 and the electric telescopic rod 18 are turned on through the PLC controller 5. The telescopic end of the electric telescopic rod 18 extends, driving the connecting block 19 and the protective plate 16 to move synchronously until the through hole 17 on the protective plate 16 moves directly below the nozzle 11, so that the protective plate 16 releases the shielding protection of the nozzle 11, facilitating the subsequent spraying of water by the nozzle 11 to cool the internal environment of the cattle shed body 1. And by opening the solenoid valve 13, the water supply pipe 9 supplies water to the water delivery pipe 22, and the water is transported to the nozzle 11 through the spray pipe 10. Finally, the water is sprayed out through the water spraying holes 12 on the nozzle 11, thereby cooling the internal environment of the cattle shed body 1 by spraying, so as to reduce the temperature and humidity index of the internal environment of the cattle shed body 1, avoid the temperature and humidity index in the cattle shed being higher than 83, and prevent the beef cattle from being in severe heat stress and affecting the fattening of the beef cattle;

[0038] When the temperature and humidity index in the cattle shed body 1 is lower than 79 (that is, it is not necessary to use the spray cooling mechanism to cool the internal environment of the cattle shed body 1), the solenoid valve 13 is closed through the PLC controller 5, and the electric telescopic rod 18 is started to make its telescopic end contract, driving the protective plate 16 to move until the through hole 17 on the protective plate 16 is in an interleaved state with the nozzle 11, thereby using the protective plate 16 to cover and protect the bottom end of the nozzle 11, avoiding the blockage of the water spraying holes 12 caused by the long-term exposure of the nozzle 11, protecting the nozzle 11, being beneficial to the subsequent normal use of the spray cooling mechanism, and improving the service life of the spray cooling mechanism.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
