Description

Technical Field

[0001] The utility model belongs to slaughtering equipment, in particular to a negative pressure blood drawing tool for poultry slaughtering. Background Art

[0002] During the poultry slaughtering process, in order to reduce the blood residue in the poultry meat and ensure the quality and safety of the poultry meat, the poultry needs to be bled. In addition, since poultry blood is a valuable resource rich in high-quality protein and other nutrients and has high economic value, the blood needs to be recovered after the poultry is bled.

[0003] Currently, poultry slaughter involves bleeding and blood recovery by making an incision in the mouth, neck, or artery. The bird is then hung upside down, and the blood, under the influence of gravity and internal pressure, drips from the incision into a blood collection trough below for recovery. This method of bleeding takes a long time and affects the quality of the meat. Furthermore, the blood collected in the blood collection trough is easily contaminated, affecting blood quality.

[0004] To address these issues, Chinese utility model patent application number 2023219763292 discloses a vacuum blood collection knife for poultry slaughter. The knife comprises a hollow handle connected to a vacuum drainage tube at its front end and a drainage hose connector at its rear end. The vacuum drainage tube is connected to a blade head, which is then connected to the vacuum mechanism's exhaust pipe. The blade head is used to puncture the poultry's blood vessels and allow the blood to flow through the vacuum drainage tube and handle into a storage device. This solution uses the blade head to sever the poultry's blood vessels. Under the influence of negative pressure, the blood in the poultry flows through the vacuum drainage tube and handle into the storage device, achieving rapid bloodletting and blood recovery, with high-quality recovered blood. However, this solution also has some problems: First, from the description, the cutter head is tubular, the lower end of which is connected to the vacuum guide tube, and the upper end is provided with an annular blade or a multi-peaked blade or a blade of other shapes. The use of an annular blade is easy to cut the outer tissue of poultry, which can easily lead to blockage of the pipeline and blood contamination, while the multi-peaked blade or the blade of other shapes is not easy to expose the incision, affecting the blood extraction effect; second, there is a lack of means to control negative pressure on the tool, which is easy to inhale debris, and the negative pressure combined with the blade will pose a safety hazard to the operator. Utility Model Content

[0005] The purpose of the utility model is to overcome the problems of existing vacuum blood collection knives for poultry slaughtering, and to provide a negative pressure blood collection tool for poultry slaughtering which can effectively improve the poultry bleeding effect and the quality of recovered blood and is relatively safe to operate.

[0006] The utility model solves the technical problem adopted by the following technical solution: a negative pressure blood drawing tool for poultry slaughtering comprises an extraction seat and a handle seat, an extraction tube and a contact tube are vertically fixed on the extraction seat, the extraction tube is located in the contact tube, the handle seat is located directly below the extraction seat, a handle is provided between the handle seat and the extraction seat, both ends of the handle are respectively fixed on the extraction seat and the handle seat, a delivery tube is provided in the handle, a negative pressure tube is provided at the lower part of the handle seat, the negative pressure tube is connected with the negative pressure vacuum device, the extraction tube is connected with the delivery tube, the delivery tube is connected with the negative pressure tube, the length of the extraction tube is 0.5-1 cm shorter than the length of the contact tube, a vertical blade is provided in the extraction tube through a bracket, a guide groove is provided on the blade, and the blade extends out of the tube mouth of the extraction tube by 0.1-0.5 cm.

[0007] Optionally, a solenoid valve is provided on the negative pressure tube, a control button is fixed on the handle seat, the solenoid valve is connected to the control button via a wire, and the control button controls the on and off of the solenoid valve.

[0008] The method of use and principle of the utility model are as follows: when in use, the negative pressure vacuum device is started, at this time the electromagnetic valve is disconnected, there is no negative pressure in the delivery tube, the handle is held, the contact tube is covered on the epidermis of the poultry's artery, the electromagnetic valve is connected by the control button, and negative pressure is formed in the extraction tube and the contact tube. Under the action of the negative pressure, the contact tube is adsorbed on the epidermis of the poultry, the epidermis of the poultry moves closer to the extraction tube, a cut is made by the blade arranged in the extraction tube, and the artery inside is cut, and the blood flows into the extraction tube along the guide groove on the blade, and then enters the negative pressure vacuum device for storage through the delivery tube and the negative pressure tube. After the blood in the poultry is extracted, the electromagnetic valve is disconnected by the control button, and the next poultry is bled; the blade with the guide groove in the built-in extraction tube can cut a bleeding hole on the poultry, and the blood is smoothly extracted from the poultry, thereby improving the poultry bleeding effect and the quality of the recovered blood; the combination of the control button and the electromagnetic valve can effectively control the generation of negative pressure, improve the safety of operation, and avoid the inhalation of impurities.

[0009] Compared with the existing technology, the beneficial effects of the present invention are as follows: the present invention can effectively improve the poultry bleeding effect and the quality of recovered blood, and the operation is relatively safe. BRIEF DESCRIPTION OF THE DRAWINGS
