Opening device for irrigation of domestic pigs

Abstract

The invention provides a drenching mouth opening device for domestic pig breeding, and discloses a mouth opening device which is used for supporting and expanding the oral cavities of domestic pigs, pressing downwards and fixing the tongue roots and facilitating drenching. The device is characterized in that one end of a lower fixed arm is arranged at one end of a lower supporting arm, the lower fixed arm is of an arc structure, one end of a lower clamping arm is arranged at one end of the lower supporting arm through a connecting shaft, and the lower clamping arm and the lower fixed arm forma U shape; one end of a transmission arm is arranged at one end of the lower clamping arm, one end of a driving rod is hinged to the other end of the transmission arm, and a hinge hole in one end of the driving rod is a kidney-shaped hole; the middle of the driving rod is hinged to the lower supporting arm through a rotating shaft, the driving rod and the lower supporting arm form an X shape, theother end of the driving rod is connected with the lower supporting rod through a compression spring, and the other end of the lower fixed arm is connected with the other end of the lower clamping armthrough a telescopic rubber tube; a tongue depressor is arranged on the telescopic rubber tube, and rubber pads are arranged on the outer edge of the other end of the lower fixed arm and the outer edge of the other edge of the lower clamping arm respectively.

Description

Technical field [0001] The invention relates to an opening device for pouring medicine for domestic pig breeding, which relates to a device for supporting and fixing the mouth of the domestic pig when pouring medicine during the breeding process of domestic pigs, and belongs to the field of animal husbandry and breeding. In particular, it relates to an opening device that supports and expands the oral cavity of a domestic pig, presses down and fixes the root of the tongue, and is convenient for filling medicine. Background technique [0002] At present, in domestic pig breeding, domestic pigs often suffer from indigestion and food accumulation due to excessive intake, which affects the feeding and growth of pigs. In order to alleviate this situation, it is necessary to carry out medication for treatment and gastrointestinal cleaning. Pigs are difficult to control when administering medicine. They resist the administering medicine and affect the progress and efficiency of administ...

Problems solved by technology

[0002] At present, in domestic pig breeding, domestic pigs often suffer from indigestion and food accumulation due to excessive food intake, which affects the feeding and growth of pigs. Pigs are difficult to control when pouring drugs, and they resist the drug feeding, which affects the progress and efficiency of drug feeding. Therefore, it is necessary to open the mouth of the pig so that the drug can be poured smoothly from the mouth. The traditional method is The pig is fixed manually, and then the mouth is opened by hand, and then another person pours the medicine, and the root of the tongue is pressed down during the medicine filling process, so as to prevent the medicine from entering the trachea, causing accidents, low efficiency, and irrigation. There are many cases where the medicine is not swallowed during the medicine process, and two people are required to cooperate. The existing medicine filling device inserts the medicine tube into the esophagus, and then pours the medicine. It is wasteful, inconvenient to operate, and the mouth still needs to be separated manually. When the pig resists, it is easy to bite the human body and cause the operator to be infected;

[0003] Publication number CN205626183U discloses a mouth gag for pigs, including an upper support frame, a connecting shaft, a coil spring, a lower support frame and a rubber pad, one end of the upper support frame and the lower support frame are connected through the connection shaft, and the upper support frame and the lower support frame are connected by the connection shaft. The inside of the support frame and the lower support frame is provided with the coil spring. This method is only to stretch the mouth of the pig. Due to the use of the coil spring structure, there will be changes in the internal support space, and there is also a maximum support angle. When pouring the medicine, the root of the tongue cannot be pressed down, and the medicine is easily injected into the esophagus, and it cannot be well clamped when the medicine is poured

[0004] Publication No. CN204636616U discloses a gag for pigs, which includes a hand-held rod, an upper jaw fixing chain, a fixing hook and a lower jaw fixing ring. A gastric tube jack is opened at the axial middle position of the hand-held rod, and the lower jaw fixing ring is located at the center of the jaw. The axial middle part of the hand-held stick, the side of the gastric tube insertion hole, the upper jaw fixation chain and the fixation hook are located on the opposite side of the mandibular fixation ring on the hand-held stick, the upper jaw fixation chain and the The fixing position of the fixing hook is axisymmetric to the gastric tube jack. This method uses a hand-held stick to stretch the upper and lower jaws. It requires the cooperation of multiple people to perform the irrigation, and the labor cost is high and the efficiency is low.
