Description

Drugs suitable for yak transportation in the Qinghai-Tibet Plateau area to reduce stress and their application methods

technical field

Background technique

At present, the existing technologies commonly used in the industry are as follows:

The yak belongs to Mammalia, Eutheria, Artiodactyla, Ruminantia, Bovidae, and Bovine subfamily animals. It is one of the unique and rare cattle species centered on the Qinghai-Tibet Plateau of China and adjacent to alpine and subalpine alpine regions. It is herbivorous. Sexual ruminants. The yak can adapt to the alpine climate and is the mammal that lives at the highest altitude (except humans) in the world. It is distributed in areas above 3,000 meters above sea level on the Qinghai-Tibet Plateau in China. Transportation is an unavoidable and important link in the process of yak breeding. Animal transportation is required in the process of yak sales, slaughter, off-site fattening, and introduction of breeding cattle. Forage (feed) resources, the production activities of fattening yaks in different places have been carried out to improve the economic and ecological benefits of yak breeding; and the requirements for environmental and ecological protection in plateau areas require that many slaughter processes must be carried out in designated slaughterhouses; Reduce yak inbreeding and promote yak blood renewal; this series of production conditions makes the transportation of yaks more and more. However, in the process of transportation, yaks will be frightened, changed in environmental conditions and living rules, and the sum of non-specific responses of this animal body to various internal and external abnormal stimuli is called stress. reaction. The greater the stress response of yaks, the greater the weight loss during transportation, resulting in great economic losses. The existing methods to reduce the stress response in the process of yak transportation are not effective and the process is relatively complicated, so they are not suitable for transportation in small transportation yards. (Existing methods for reducing stress during yak transportation are relatively simple and extensive, and there are no systematic and reasonable measures to reduce stress. In the actual transportation process, yaks often lose weight, sometimes get sick or die, reduce the benefits of yak breeding, and reduce agricultural and animal husbandry. income and corporate efficiency.)

In summary, the problems in the prior art are:

The existing methods to reduce the stress response in the process of yak transportation are not effective and the process is relatively complicated, so they are not suitable for transportation in small transportation yards.

Existing methods (techniques) for mitigating transport stress are only applicable to ordinary cattle and beef cattle, which are transported in plain areas, and yaks are more wild and have completely different living habits and behavioral characteristics from ordinary cattle. and methods add a certain degree of difficulty.

The difficulty and significance of solving the above technical problems:

Yak is a semi-wild domestic animal that grows in the Qinghai-Tibet Plateau at an altitude of more than 3,000 meters. It is more difficult to transport than beef cattle. It often causes cows to crush each other, suffer from severe stress, get sick or die during transportation. , Injury and other incidents. The yaks were greatly stimulated by excessive fright, and farmers and herdsmen lacked awareness of animal welfare protection, and the transportation methods and processes were relatively simple and extensive, resulting in a greater stress response to yak transportation, and a large number of yaks lost weight after transportation. In serious cases, it will cause yak disease or directly cause death, which will not only reduce the income of farmers and herdsmen from yak breeding, but also have a non-negligible impact on the benefits of yak breeding.

The working principle of the present invention is described below in conjunction with accompanying drawing:

Make the cylinder 2 and the rotary shaft 30 rotate clockwise as shown in Figures 4 and 5, pass hot air into the cylinder 2 at the hot air supply port 22, and then put the processed object from the input device 4 from the input port 20 to the cylinder 2 invest in. The processed object D is conveyed to the exit side by the conveying device 27 in the sending direction, scraped and dropped by the scraping conveying device 28 provided, and then collides with the stirring part to be broken and scattered in the cylinder 2 . The treated matter is effectively contacted with hot air while being scattered in the cylinder, and is dried. As shown in FIG. 6, the agitating part 33 is not provided with an angle, so after the collision, the treated matter is ejected towards the exit direction of the cylinder 2. The processed object is subjected to this series of actions and slowly moves towards the exit.

When the above-mentioned cylinder 2 is rotating, when the processed object D is conveyed to the entrance, a part of the processed object with a low moisture content on the exit side is conveyed back to the entrance by the reverse direction conveying device 29 with an angle. side. This part is transported back to the treated object D with low moisture content at the entrance and the treated object D with high moisture content and strong adhesion that has just been put in through the scraping and dropping action of the scraping and conveying device 28, as well as the stirring part. The crushing effect is mixed. This mixture has a lower water content than the treated product just put in, and its adhesion is weak, so it will not stick near the inlet, causing blockage inside the cylinder, and will not stick inside the cylinder 2 to cause irregular adhesion. A large amount of substances are peeled off, and there will be no problems such as low contact efficiency with hot air due to reduced dispersibility. Therefore, the water content of the treated product D after the drying treatment is constant, and the discharge amount is also constant.

The processed product D not returned by the reverse direction conveying device 29 directly reaches the outlet weir 24, passes through the outlet weir to the discharge port 21, and is discharged from the discharge port.

The temperature of the hot air is lowered due to the drying action, and it is discharged from the exhaust port 23 together with the evaporated moisture in the processed object D.

The reverse direction conveying device 29 is based on the length L of the cylinder, and is set up to 30% from the input side, that is, as close as possible to the input side during installation. Otherwise, the conveyed object D from the conveying device 27 in the sending direction to the exit side and the processed object D conveyed to the inlet side by the conveying device 29 in the opposite direction may concentrate at the part where the conveying device 27 in the sending direction and the conveyed object D on the exit side are close to each other, which may cause a cylinder 2 A state of blockage occurs.

Reverse direction conveying device 29, based on the long L of the cylinder, starts from the input side to 90% of the rear, that is, is arranged as close to the outlet side as possible until the input side. The action of conveying the processed object back to the entrance by the reverse direction conveying device 29 is performed before the processed object passes through the outlet weir 24, otherwise the amount of processed object discharged from the discharge port 21 will vary greatly. In this case, it is necessary to add equipment not shown in the figure after the discharge port 21 to deal with the fluctuating discharge amount generated, and a large-scale equipment must be installed, which increases the cost of the equipment and makes the control of the equipment more troublesome.

For the reverse direction conveying device, when the angle with respect to the cylinder axis is less than 5°, the amount of processed objects D returned by the reverse direction conveying device 29 is greatly reduced, and the processed objects are not sufficiently returned to the inlet side.

For the reverse direction conveying device, when the angle with respect to the axis of the cylinder is greater than 30°, the amount of processed object D returned by the reverse direction conveying device 29 is too much, and the amount of processed object D retained in the cylinder increases significantly. The load on part 3 damages the stirring part 3.
