Description

Technical Field

[0001] This utility model relates to the field of slaughtering equipment technology, specifically a control device for bleeding pigs during slaughter. Background Technology

[0002] Slaughtering equipment is specialized meat processing machinery used to slaughter livestock such as pigs, cattle, sheep, chickens, and ducks. In the pig processing procedure, bleeding is necessary before cutting and sorting. Bleeding is a crucial step in pig slaughtering; the bleeding time and amount must be appropriate to ensure complete blood removal. Otherwise, excessive hemoglobin residue will remain in the pig's body, affecting the color and taste of fresh pork. Excessive hemoglobin can also accelerate the growth and reproduction of microorganisms in fresh meat, hindering transportation and storage.

[0003] According to a bloodletting and conveying device for pig slaughter (Announcement No.: CN216834381U), the above application utilizes pressure difference to effectively prevent pig blood from coagulating and blocking at the bloodletting tube and to effectively increase the speed and efficiency of bloodletting and conveying.

[0004] However, in actual use, although the above-mentioned equipment can fix the blood-drawing needle structure to the artery of the pig by strapping, the blood-drawing process is relatively long and the needle is in a relatively negative pressure state for a long time. Therefore, the pig's tissue structure is prone to adhering to the needle, affecting the normal blood transfusion effect of the needle, and causing blockage, so that the equipment cannot perform the blood-drawing effect normally. In view of this, we propose a control device for blood-drawing in pig slaughter. Utility Model Content

[0005] The purpose of this invention is to provide a control device for bleeding pigs during slaughter, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a control device for bleeding during pig slaughter, comprising a bleeding machine, wherein a connecting hose is fixedly connected to the input end of the bleeding machine, a syringe is fixedly installed at the end of the connecting hose away from the bleeding machine, a strap is fitted on the outside of the syringe, and an anti-blocking component is provided at the top of the syringe to prevent the soft tissue of the pig from blocking the flow.

[0007] The anti-clogging component includes a triangular cone, which is fixedly installed at the end of the syringe away from the connecting tubing. The outer surface of the triangular cone has a spiral groove, and the bottom inner wall of the spiral groove has a through hole.

[0008] Preferably, the triangular cone is cone-shaped and hollow inside, so that blood from the pig's artery can pass through the triangular cone into the syringe.

[0009] Preferably, the spiral groove is fitted to the outer surface of the triangular cone, and the number of through holes is set in multiple sets. The multiple sets of through holes are evenly distributed in the spiral groove, and the through holes are connected to the internal cavity of the triangular cone. A certain gap is still maintained between the outer surface of the triangular cone and the pig tissue, so that blood can enter the syringe through the spiral groove and through holes and be released outward.

[0010] Preferably, an attachment assembly is provided on the outer side of the top end of the syringe. The attachment assembly includes an outer ring, which is slidably mounted on the outer surface of the syringe. An inner ring is fixedly connected to the inner surface of the outer ring. A piston rod is fixedly connected to the side wall of the inner ring. A piston plate is fixedly connected to the end of the piston rod away from the inner ring. A piston cavity is formed on the inner wall of the syringe. An attachment airbag is fixedly installed at the end of the syringe away from the connecting tubing.

[0011] Preferably, the piston chamber is connected to the internal cavity of the attached airbag, and the side wall of the piston plate is fixedly connected to the side wall of the attached airbag. The attached airbag and the piston chamber are filled with inert gas, thereby avoiding the large temperature changes in the external environment from affecting the size of the attached airbag.

[0012] Preferably, the side wall of the syringe has a rectangular groove with a width that matches the width of the connection between the inner and outer rings, and the connection between the inner and outer rings slides in the rectangular groove to ensure that the outer and inner rings do not rotate on the outside of the syringe.

[0013] Preferably, the outer ring is positioned on the side of the strap near the triangular cone, while the attachment airbag is positioned near the top of the syringe.

[0014] Compared with the prior art, this utility model provides a control device for bleeding pigs during slaughter, which has the following beneficial effects:

[0015] 1. This control device for bloodletting in pig slaughtering features a triangular cone structure with spiral grooves and through holes. After the needle pierces the pig's artery, the spiral grooves form a stable blood flow channel between the cone surface and the surrounding soft tissue, effectively preventing tissue adsorption and blockage of the bloodletting passage due to prolonged negative pressure suction. Multiple evenly distributed through holes further disperse the blood inlet, ensuring that even when the local channel is blocked, blood can still smoothly enter the syringe, thereby improving the reliability and thoroughness of bloodletting and preventing the problem of low bloodletting efficiency caused by blockage.

[0016] 2. This control device for bleeding in pig slaughter utilizes a linkage mechanism that is automatically triggered when the strap is tightened. This mechanism drives the piston structure to compress inert gas, causing the attached airbag to expand evenly and fit tightly around the bleeding port. This effectively seals the puncture site, preventing the syringe from shifting during blood draw and affecting the bleeding effect. It also prevents blood from seeping or splashing from around the wound, improving the hygiene conditions at the slaughtering site and enhancing the stability and controllability of the entire bleeding process.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a control device for bleeding pigs during slaughter, including a bleeding machine 1, a connecting hose 2 fixedly connected to the input end of the bleeding machine 1, a syringe 3 fixedly installed at the end of the connecting hose 2 away from the bleeding machine 1, a strap 4 sleeved on the outside of the syringe 3, and an anti-blocking component 5 provided at the top of the syringe 3 to prevent the soft tissue of the pig from blocking the flow, the anti-blocking component 5 including a triangular cone 51, a spiral groove 52 and a through hole 53.

[0024] In one embodiment of this utility model, a triangular cone 51 is fixedly installed at the end of the syringe 3 away from the connecting tubing 2. A spiral groove 52 is provided on the outer surface of the triangular cone 51, and a through hole 53 is provided on the bottom inner wall of the spiral groove 52.

[0025] Furthermore, the bleeding machine 1 adopts a negative pressure blood collection device. In actual operation, the syringe 3 is inserted into the artery of the slaughtered pig. After the bleeding machine 1 is started, the blood of the pig can be released through the syringe 3 and the connecting tubing 2. The bleeding machine 1 can also integrate an adjustable flow valve and an infrared blood flow monitoring module to control the bleeding time to 3-5 minutes, avoiding the fishy smell of meat caused by incomplete bleeding. In addition, the strap 4 can adapt to the fixation needs of pigs of different sizes, ensuring the relative stability of the syringe 3 during the bleeding process.

[0026] Meanwhile, the triangular cone 51 is cone-shaped and hollow inside, allowing blood from the pig's arteries to enter the syringe 3 through the cone. Additionally, the spiral groove 52 fits onto the outer surface of the cone 51. Furthermore, multiple sets of through holes 53 are evenly distributed within the spiral groove 52 and are connected to the internal cavity of the cone 51. Due to the spiral groove 52, a certain gap remains between the outer surface of the cone 51 and the pig's tissue, facilitating blood flow through the spiral groove 52 and through holes 53 into the syringe 3 and outwards. This solves the problem of blocked bloodletting ports under negative pressure within the pig's body, which affects normal bloodletting efficiency.

[0027] Additionally, please refer to the instruction manual appendix. Figures 3-5 An attachment component 6 is provided on the outer side of the top of the syringe 3. The attachment component 6 includes an outer ring 61, which is slidably mounted on the outer surface of the syringe 3. An inner ring 62 is fixedly connected to the inner surface of the outer ring 61. A piston rod 63 is fixedly connected to the side wall of the inner ring 62. A piston plate 64 is fixedly connected to the end of the piston rod 63 away from the inner ring 62. A piston cavity 65 is opened on the inner wall of the syringe 3. An attachment airbag 66 is fixedly installed at the end of the syringe 3 away from the connecting tubing 2.

[0028] In this embodiment of the invention, the piston chamber 65 is connected to the internal cavity of the attached airbag 66, and the side wall of the piston plate 64 is fixedly connected to the side wall of the attached airbag 66. The attached airbag 66 and the piston chamber 65 are filled with inert gas to prevent significant temperature changes in the external environment from affecting the volume of the attached airbag 66. Furthermore, the side wall of the syringe 3 has a rectangular groove with a width matching the width of the connection between the inner ring 62 and the outer ring 61. The connection between the inner ring 62 and the outer ring 61 slides within this rectangular groove to ensure that the outer ring 61 and the inner ring 62 do not rotate outside the syringe 3, but can... Moving along the radial direction of the syringe 3, the outer ring 61 is located on the side of the strap 4 near the triangular cone 51, and the attached air bladder 66 is located near the top of the syringe 3. Therefore, when the strap 4 is tied around the pig's neck, due to the tightening of the strap 4, the outer ring 61 and the inner ring 62 will move along the outer wall of the syringe 3 towards the triangular cone 51, thereby squeezing the piston chamber 65 through the piston plate 64. This causes the attached air bladder 66, which is attached to the outside of the pig's bleeding port, to expand and enlarge, so as to press and seal the outside of the pig's bleeding port, ensuring that the blood-drawing machine 1 can perform blood-drawing operations more stably, and also preventing the pig's blood from splashing and affecting the pig slaughtering operation environment.

[0029] In this invention, during use, the syringe 3 is fixed to the carotid artery of a slaughtered pig using a strap 4, allowing the triangular cone 51 to be inserted into the artery. After the bloodletting machine 1 is started, it generates negative pressure to draw blood through the connecting hose 2 and the syringe 3. The blood flows in from the outside of the triangular cone 51 through the spiral groove 52, and then enters the internal cavity of the triangular cone 51 through multiple sets of through holes 53 evenly distributed at the bottom of the spiral groove 52. Finally, it flows into the syringe 3 and is discharged along the connecting hose 2. The design of the spiral groove 52 creates a gap between the outer surface of the triangular cone 51 and the pig tissue. This effectively prevents soft tissue from adhering and clogging the through-hole 53 due to negative pressure, ensuring a smooth bleeding process. At the same time, during the tightening process, the strap 4 pushes the outer ring 61 and inner ring 62 to move along the syringe 3 towards the triangular cone 51, causing the piston rod 63 and piston plate 64 to move in the piston chamber 65, squeezing the inert gas filled therein, causing the attachment airbag 66 to expand and tightly adhere to the outside of the pig's bleeding port. This adhesion not only enhances the stability of the syringe 3 during the bleeding process, but also effectively prevents blood from splashing out, maintaining the cleanliness of the slaughtering environment.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
