Detailed Description

The technical solution of the present invention will be described in further detail below with reference to the following embodiments, but the present invention is not limited to the following embodiments.

The utility model provides a pasture cooling system and a control method of pasture cooling equipment. The pasture cooling device may include, for example, a spray device, a fan, a fog-making device, and the like.

The system and method according to the invention will be described below by way of example of a spray device, but the invention may include a spray device, a fan, a mist-making device or a combination thereof, or other possible cooling devices and any combination. Preferably, the mist generating device is generally arranged in connection with a fan, so that the formed mist is conveyed by the fan.

Fig. 1-4 show a cooling system and a control method according to an embodiment of the present invention, the cooling device comprising a spraying device.

As shown in fig. 1, the pasture cooling system according to the utility model mainly comprises: a plurality of sensors 9, each sensor capable of detecting the swinging of a corresponding one of the neck cangues 3; a plurality of cooling devices, i.e. spray heads 7, each spray head being associated with a cow position of a corresponding neck flail swing arm 3, and each spray head 7 being individually activatable and deactivatable; and a controller (not shown) capable of receiving signals from the sensor 9 and thereby detecting the behaviour of the cow; and starts or stops the spray head 7 corresponding to the position of the cow in which the cow is located according to the detected cow behavior.

the neck cangue is used for guiding and managing the cattle to eat and mainly comprises a neck cangue frame upper square pipe 1, a neck cangue frame lower square pipe 2, a neck cangue swing arm 3, a connecting rod 4, a connecting rod 5 and a control lever 6. The connecting rod 4 and the connecting rod 5 connect the upper tube 1 of the neck cangue frame and the lower tube 2 of the neck cangue frame. The middle part of the neck strap swing arm 3 is pivotally supported on the connecting rod 4 by a bracket and can swing around the bracket. The position shown in fig. 1 can be maintained by the neck strap by providing suitable means, such as a biasing spring or the like, when the square frame is divided into two parts by the neck strap swing arm 3. The lower space part is provided with a blocking part, so that the cattle can only enter through the upper space part and push the neck cangue swing arm 3 to rotate when the head is lowered for feeding. When necessary, the position of the flail swing arm 3 can be locked by the operating rod, so that the cattle can not exit the flail.

As shown in fig. 2-4, the spray head 7 is connected to a shower 10 and spraying can be performed in a controlled manner by means of a control box 8. Wiring conduits 11 may also be provided for corresponding wiring connections. In some embodiments, a wireless connection may be made, thereby eliminating the need for wiring conduit 11.

The end part of the neck cangue is provided with a vertical column 12 for fixing the neck cangue. A control box 13 housing the controller may be provided on the column 12.

In fig. 1, 3 neck flail swing arms 3 are shown, but a neck flail according to the invention may comprise any number of neck flail swing arms 3. The controller may be installed in the control box 13, for example, and connected to the sensor 9 and the shower head 7 by wire or wirelessly.

The spray head 7 is connected to the shower pipe 10, and can control water of a proper temperature to spray water from the shower pipe 10 to a corresponding area. When the cooling device is a fan, the fan may be mounted above the area, for example, suspended from a roof.

when the cattle only needs to eat, the head of the cattle enters from the space above the left side of the neck cangue swing arm 3, and when the head of the cattle eats downwards, the neck of the cattle pushes the neck cangue swing arm 3 to rotate around the swing arm support. For example, in fig. 1, a sensor 9 mounted in connection with the neck flail swing arm 3 detects the exit of the upper end of the neck flail swing arm 3 and thus the swinging of the neck flail swing arm 3. The sensor 9 may be, for example, a proximity switch.

Other sensors and mounting means may be used, such as angle switches, magnetic induction switches and three-axis sensors, which may be mounted on the neck flail swing arm 3. When the cow is loaded or withdrawn, the neck cangue swing arm 3 swings, and then the angle change can be generated, and the angle switch and the three-axis sensor which are installed on the neck cangue swing arm 3 are triggered to form a detection signal. The working principle of the magnetic induction switch is similar to that of a proximity switch, the two parts of the magnetic induction switch are respectively arranged at a certain fixed position of the neck cangue swing arm 3 and a certain fixed position of the neck cangue, and the two parts of the magnetic induction switch can be separated or contacted by the swinging of the neck cangue swing arm 3 to respectively generate corresponding detection signals.

The cooling system according to the invention can be activated under predetermined conditions, for example, when the season is summer daytime.

and when the controller detects the feeding behavior of the cattle under the preset condition, the controller starts the cooling equipment corresponding to the position of the cattle where the cattle is located. At the moment, the cattle only eats, and the corresponding spray head 7 is started to spray to the position of the cattle, so that the cattle can be accurately sprayed.

The predetermined condition includes a relationship between a current temperature, humidity and/or temperature and humidity index and a preset threshold. For example, when the temperature is greater than a predetermined threshold (e.g., 20 ℃), it may be considered that a predetermined condition for activating a temperature reduction device (e.g., a spray device, a fan, and/or a fogging device) is satisfied. Alternatively, when the humidity is greater than a preset threshold, it may be considered that a predetermined condition for activating a temperature reduction device (e.g., a fan) is satisfied. Alternatively, when the humidity is less than a preset threshold, it may be considered that a predetermined condition for starting the cooling device (e.g., a spraying device or a mist generating device and a fan) is satisfied. Alternatively, when the temperature and humidity indication is greater than a preset threshold, it may be considered that a predetermined condition for starting the temperature reduction device (the spraying device, the fan, and/or the mist generating device) is satisfied.

These parameters and corresponding thresholds may be selected or adjusted based on practical experience. The predetermined condition may refer to a certain parameter, or may refer to a combination of two or more parameters.

The temperature-humidity index (THI) is an index for evaluating the degree of heat of the environment by combining the air temperature and the air humidity, is also called as a discomfort index, and is generally used for evaluating whether livestock and poultry are in a heat stress state and the degree of the heat stress state in the process of breeding the livestock and poultry. The temperature and humidity index is a classical index for evaluating the heat stress state of animals commonly used in livestock breeding.

The controller can execute different control strategies on different cooling devices according to the relation between the current temperature, humidity or temperature and humidity index and a preset threshold value.

For example, the control strategy of the fan may be determined according to the temperature, or may be determined according to the Temperature and Humidity Index (THI). The fixed frequency fan can be started when the temperature is higher than 20 ℃ or can be started when the THI is higher than 68. The variable frequency fan can be progressively started, for example, when the temperature is more than 20 ℃, the maximum rotating speed is started to be 20%; when the temperature is more than 25 ℃, the temperature is opened by 50 percent; at a temperature > 28 ℃ the switch is turned on 100%.

It should be noted that the starting conditions (temperature or THI) of the fan are not fixed and can be adjusted.

similarly, according to the size (or the relation with the preset threshold value) of the temperature, the humidity and/or the temperature and humidity index, the control intensity of the spraying equipment can be adjusted at any time or can be set to be opened at intervals for a preset time period. As an example, the spray device may be set to turn on for 1 minute every 15 minutes at a temperature > 25 ℃; opening every 10 minutes for 1 minute at a temperature > 28 ℃; turn on every 5 minutes for 1 minute at a temperature > 30 ℃.

Likewise, it should be noted that the start-up conditions (temperature or THI) of the spray equipment are not fixed and can be adjusted.

Similarly, the fogging device can apply different fogging intensities according to the temperature and humidity index THI.

The above control strategies are merely exemplary, and other control strategies are possible.

Thus, when the cattle are only eating all the time, proper cooling measures are ensured, and excessive cooling is avoided.

When the controller detects that the cattle only exits the neck cangues, the temperature reduction device corresponding to the position of the cattle where the cattle is located is stopped. For example, as shown in fig. 1, when the cow exits the neck cangue, the neck cangue swing arm 3 returns to the original position, and the upper end of the neck cangue swing arm 3 contacts or approaches the sensor 9, so that the sensor 9 detects the cow. That is, when the end of the flail swing arm 3 is reset to the initial position or the swing angle becomes 0 degree, it is detected that the cow exits the flail only. When the controller receives or detects the signal, the corresponding spray head stops spraying, so that useless spraying is avoided, and water is saved.

According to the embodiment of the present invention, a sensor may be installed at the associated position of each neck yoke swing arm 3 to detect the swinging of the neck yoke swing arm 3. This allows the behaviour of the cow at each neck cangue swing arm 3 to be detected and controlled accordingly.

As mentioned above, the sensor can be mounted to the operating lever support of the neck yoke, or the sensor can be mounted directly to the neck yoke swing arm 3, or the sensor can be mounted to another location of the neck yoke. The operating rod support supports and installs the operating rod 6 on the upper square pipe 1 of the neck cangue frame.

The controller detects the feeding behavior of the cattle and the behavior that the cattle exits the neck cangues through the swinging of the neck cangue swinging arms 3 detected by the sensors. For example, when the sensor detects that the end of the neck flail swing arm 3 leaves the initial position by more than or equal to a predetermined distance (e.g., 5mm) or the swing angle of the neck flail swing arm 3 is more than or equal to a predetermined angle (e.g., an angle between 2 degrees and 5 degrees), the controller detects the feeding behavior of the cow.

According to the utility model discloses, cooling device can be for spraying equipment and/or fan and/or make fog equipment. In some embodiments, only a spraying device is provided. In some embodiments, only a fan is provided. In some embodiments, both a spray device and a fan are provided. In some embodiments, both fogging and fans are provided. In some embodiments, a spray device and fan are provided in association with each neck flail swing arm 3. In some embodiments, spraying equipment may also be provided in association with a portion of the neck flail swing arm 3 and a fan may be provided in association with a portion of the neck flail swing arm 3. The cooling equipment can be connected with

Preferably, a cooling device is provided corresponding to the position of the cow at each neck flail swing arm 3 (or in association with each neck flail swing arm 3). For example, a spray head is arranged near each neck cangue swing arm 3, so that only the cattle entering the neck cangue is sprayed. The cooling device can be mounted near (front-back or above) the neck cangue, for example, corresponding to the position of the cow.

In some embodiments, one cooling device may correspond to a cow position at multiple adjacent neck flail swing arms 3 (or associated with multiple adjacent neck flail swing arms 3). For example, when a large fan is provided, one fan can blow and cool the cow at several adjacent flail swing arms 3 at the same time. In this case, the control strategy of the cooling device may be adjusted, that is, as long as cattle are detected to go on or feed at the flail swing arms 3 in the region corresponding to the cooling device, the device is started; the cooling device is stopped only when no cattle feed is fed at the plurality of neck cangue swing arms 3.

For the detection of the sensor, a delay on or a delay off can be set on the controller. If the cattle only touches the neck cangue swing arm 3 and does not eat by the neck cangue completely, the false action of the cattle can be filtered out by delaying opening (for example, opening after 3 seconds). Similarly, the delayed turn-off may filter out the condition that the cow has only exited but has not exited completely.

In other embodiments, infrared or ultrasonic detection can be used to detect the feeding behavior of the cattle.

Fig. 5 shows a schematic view of another embodiment according to the invention. In this embodiment, 2, 3 or more solenoid valves 16 for controlling the cooling device may be controlled using 1 control box 8, wherein each solenoid valve 16 operates independently from the cow behaviour at the corresponding neck flail. In fig. 5, three solenoid valves 16 may be connected to 1 control box 8, and the connected solenoid valves 16 are operated by the control box 8. Each solenoid valve 16 controls a corresponding spray head 7.

In the embodiment of fig. 5, the sensor 8 is a three-axis sensor, which is installed near the connection of the flail swing arm 3 and the swing arm support seat 15, and detects the cow behavior by detecting the swing of the flail swing arm 3.

The operating rod 6 is mounted on the upper tube 1 of the neck yoke frame by means of an operating rod bracket 14.

Other aspects according to the present embodiment are configured or operated similarly to the above embodiments, and are not described again.

The embodiments of the present invention are not limited to the above-described embodiments, and those skilled in the art can make various changes and modifications in form and detail without departing from the spirit and scope of the present invention, and these are all considered to fall within the scope of the present invention.
