Description

Technical Field

[0001] This utility model relates to the field of live oviposition in dairy and beef cattle, specifically a restraint frame for live oviposition in cattle. Background Technology

[0002] Embryo engineering technology originated in developed countries in Europe and America. It is an effective way for cattle farms to quickly establish and expand their core breeding populations of superior breeds. It represents another major reform in livestock breeding technology after artificial insemination in livestock production.

[0003] This has now become a cutting-edge research area and an essential topic. Live oocyte retrieval technology, as a crucial aspect of embryo engineering, refers to the process of extracting oocytes from follicles in the ovaries of cattle while they are still alive, using equipment such as ultrasound and retrieval needles, followed by in vitro fertilization and embryo culture. However, cattle are prone to resistance and movement during oocyte retrieval; therefore, the effectiveness of restraint directly impacts the surgical outcome and the quantity and quality of embryos produced, thus affecting the widespread adoption of embryo technology. To address this, this application proposes a restraint frame for live oocyte retrieval in cattle. Utility Model Content

[0004] The purpose of this invention is to provide a restraint frame for live cattle egg collection, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a restraint frame for live cattle oviposition, comprising a top frame and a bottom frame arranged in parallel. Both the top and bottom frames are hollow structures, and several side tubes are fixedly connected to the bottom of the top frame and the top of the bottom frame on both sides. Rotating rods are rotatably installed on the front sides of the top and bottom frames, and horizontal bars are fixedly connected to the top and bottom ends of the two rotating rods that are close to each other. Since the two horizontal bars are parallel in the vertical direction, there must be several vertical tubes between them. Several mounting seats are fixedly connected to the top end of one side of the top frame. A connecting arm is rotatably connected to one side of each mounting seat via a rotating shaft. Vertically distributed oblique pins are fixedly installed on the connecting arm near the center of the two rotating rods. Inserts that engage with the oblique pins are fixedly installed on the outer and inner sides of the top frame, respectively. Adjustment components are movably installed on the inner sides of the top and bottom frames that are close to each other.

[0006] Preferably, the top and bottom ends of each of the rotating rods are rotatably connected to the bottom end of the top frame and the top end of the bottom frame, respectively, and each oblique pin has an oblique conical structure in the vertical direction.

[0007] Preferably, there are two mounting bases, and the two mounting bases are symmetrically distributed along the outer and inner sides of the top frame. The bottom end of each of the oblique pins extends through the sleeve to the bottom of the crossbar near the side of the top frame.

[0008] Preferably, a sliding rod is fixedly connected to the inner side of the top frame near the mounting base, and a sliding sleeve is slidably sleeved on the outer side of the sliding rod, with side mounting rods fixedly connected to both sides of the sliding sleeve.

[0009] Preferably, each of the side mounting rods is hinged to a crank block near the bottom front end of the top frame, and each crank block is hinged to a connecting block at the end away from the side mounting rod, and the end of each connecting block away from the crank block is fixedly connected to one end of a crossbar on one side.

[0010] Preferably, the adjustment assembly includes a side adjustment frame arranged vertically between the top frame and the bottom frame, and horizontal plates are arranged parallel to each other at the top and bottom of both sides of the side adjustment frame. Each horizontal plate is hinged to the top and bottom of both sides of the side adjustment frame on the side closest to the side adjustment frame, and the other side of each horizontal plate is hinged to one end of the connecting seat.

[0011] Preferably, one end of each of the connecting seats is fixedly connected to the bottom end of the top frame and the top end of the bottom frame, and a fixing tube is fixedly connected between two horizontal plates located in the same vertical direction.

[0012] Preferably, each of the aforementioned inserts is located at the center of the top frame on the side away from the adjustment component, and a tightening rope with a tensioner is provided on the rear side of the side tube and the rotating rod. One end of the tightening rope is fixed to a crossbar on one side between the top frame and the bottom frame, and the other end of the tightening rope is fixedly installed to the outside of the side tube on the side away from the adjustment component via a hook.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. To ensure the safety of oocyte collection personnel and reduce the occurrence of accidents, during the oocyte collection process, the operator stands behind the cow, with one hand inserted into the rectum to grasp the ovary, and the other hand outside the cow, using an oocyte collection needle to puncture the cow's cervix and ovary to retrieve the eggs. Due to pain protection, the cow will kick backward to expel the stimulation. This utility model facilitates the restriction of the cow's tail, which can effectively control the cow's backward kick and prevent injury to the operator. At the same time, the structure of this utility model can also restrict the sides of the cow, which can prevent the risk of the oocyte collection needle accidentally injuring the operator's hand due to the cow's left and right swinging.

[0015] 2. Protect cattle from additional harm beyond normal egg collection. If the cattle are not properly restrained, they may be shaken from side to side or back to back during the egg collection procedure. This can easily cause the retrieval needle to scratch the uterus, ovaries and other internal organs, increasing the damage to the cattle and even leading to their death. The structure of this utility model can ensure that the cattle remain standing still to the maximum extent, thereby protecting them from additional harm.

[0016] 3. Excellent restraint effect: Compared with the limitations of the existing technology, the structure of this utility model can meet the restraint work of cattle of different lengths and weights, and the restraint quality is good. It is very beneficial to the micro-operation of live oocyte collection from different cattle, and plays an important role in improving the quality of oocyte collection and increasing the blastocyst rate of embryo production.

[0017] 4. The design is ingenious, the structure is simple, and the cost is low. While ensuring the quality of cattle restraint, the structure is ingeniously simplified. It has the characteristics of simple design and few parts. Not only is the cost low, but it is also not easy to be damaged. It is very suitable for the restraint of large and strong animals such as dairy cows and beef cattle, and it is very suitable for promotion and use on ranches. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-7 The diagram shows a live cattle egg collection restraint frame, comprising a top frame 1 and a bottom frame 2 arranged in parallel. Both the top frame 1 and the bottom frame 2 are hollow structures. Several side tubes 3 are fixedly connected to the bottom of the top frame 1 and the top of the bottom frame 2 on both sides. Rotating rods 4 are rotatably installed on the front of the top frame 1 and the bottom of the bottom frame 2. Horizontal bars 5 are fixedly connected to the top and bottom of the two rotating rods 4 that are close to each other. Since the two horizontal bars 5 are parallel in the vertical direction, there must be several vertical tubes 6 between them. Several mounting seats 7 are fixedly connected to the top of one side of the top frame 1. Each mounting seat 7 is rotatably connected to a connecting arm 8 via a pivot. Vertically distributed oblique pins 9 are fixedly installed on the connecting arm 8 near the center of the two rotating rods 4. Insert sleeves 10 that engage with the oblique pins 9 are fixedly installed on the outer and inner sides of the top frame 1. Adjustment components 11 are movably installed on the inner side of the top frame 1 and the bottom frame 2 that are close to each other.

[0029] In this embodiment, the top and bottom ends of each rotating rod 4 are rotatably connected to the bottom end of the top frame 1 and the top end of the bottom frame 2, respectively. Each inclined pin 9 has a sloping conical structure in the vertical direction. There are two mounting seats 7, which are symmetrically distributed along the outer and inner sides of the top frame 1. The bottom end of each inclined pin 9 extends through the sleeve 10 to the bottom of the crossbar 5 near the side of the top frame 1. A sliding rod 12 is fixedly connected to the inner side of the top frame 1 near the mounting seat 7, and a sliding sleeve 13 is slidably sleeved on the outer side of the sliding rod 12. Side mounting rods 14 are fixedly connected to both sides of the sliding sleeve 13. A crank block 15 is hinged to the bottom end of each side mounting rod 14 near the front side of the top frame 1, and a connecting block 16 is hinged to the end of each crank block 15 away from the side mounting rod 14. The end of each connecting block 16 away from the crank block 15 is fixedly connected to one end of the crossbar 5 on one side. The adjustment assembly 11 includes a vertically oriented... A side adjustment frame 113 is placed between the top frame 1 and the bottom frame 2. Horizontal plates 112 are arranged parallel to each other on the top and bottom ends of both sides of the side adjustment frame 113. Each horizontal plate 112 is hinged to the top and bottom ends of both sides of the side adjustment frame 113 on the side closest to the side adjustment frame 113. The other side of each horizontal plate 112 is hinged to one end of a connecting seat 111. One end of each connecting seat 111 is fixedly connected to the bottom end of the top frame 1 and the top end of the bottom frame 2. A fixing tube 114 is fixedly connected between two horizontal plates 112 located in the same vertical direction. Each insert 10 is located at the center of the top frame 1 on the side away from the adjustment component 11. A tightening rope with a tightening device 17 is provided on the rear side of the side tube 3 and the rotating rod 4. One end of the tightening rope is fixed to the horizontal bar on one side between the top frame 1 and the bottom frame 2. The other end of the tightening rope is fixedly installed on the outside of the side tube 3 on the side away from the adjustment component 11 by a hook.

[0030] Furthermore, the cattle are driven into the space between the top frame 1 and the bottom frame 2 from the rear side away from the crossbar 5. Multiple side tubes 3, which are fixedly connected to both sides of the top frame 1 and the bottom frame 2, limit the cattle on both sides. The crossbars 5 on the front side of the top frame 1 and the bottom frame 2 are rotatably connected to the top frame 1 and the bottom frame 2 through corresponding rotating rods 4. The cattle are driven into the space between the top frame 1 and the bottom frame 2 and move forward towards the top frame 1. The shoulders of the cattle push the vertical tubes 6 on both sides forward, which in turn drives the two crossbars 5 to gradually close. This causes the crossbars 5 to press the inclined part of the inclined pin 9 on the inner side of the top frame 1, thereby pulling the inclined pin 9 on the inner side of the top frame 1 out of the sleeve 10. After the cow's head passes through the area between the two crossbars 5, the two crossbars 5 are completely closed. The inclined pin 9 on the inner side of the top frame 1 returns to the sleeve 10 by its own weight. The inclined pin 9 abuts against one side of each crossbar 5 to limit the cow's head. The bottom of the inclined pin 9 is inclined. At the same time, the crossbars 5 return to their original state. The inclined pin 9 needs to be lifted manually.

[0031] In order to ensure the synchronicity of the movement of the two crossbars 5, the inner side of each crossbar 5 near the top of the top frame 1 is fixedly connected to one end of the connecting block 16. So when the vertical tube 6 at the bottom of one of the crossbars 5 comes into contact with the cow's body and moves, it drives the connecting block 16 to move. Through the transmission of the crank block 15 and the side mounting rod 14, the sliding sleeve 13 can slide along the outside of the sliding rod 12. This drives the connecting block 16 on the other side of the sliding sleeve 13 to drive the other crossbar 5 to move accordingly, thus performing a synchronous switching process.

[0032] In this embodiment, an adjustment assembly 11 is also provided between the top frame 1 and the bottom frame 2. The adjustment assembly 11 includes a side adjustment frame 113 arranged parallel to the side tube 3. The top and bottom ends of the two sides of the side adjustment frame 113 are rotatably connected to the corresponding horizontal plates 112, and the other end of the horizontal plate 112 is hinged to the connecting seat 111 fixedly connected to the bottom end of the top frame 1 and the top end of the bottom frame 2, so that the distance between the side adjustment frame 113 and the side tube 3 can be adjusted by pulling the side adjustment frame 113, and the cattle can be fixed in an adjustable manner on both sides. A tightening rope with a tightening device is provided on the rear side of the top frame 1 and the bottom frame 2. One end of the tightening rope is fixed to the side mounting rod 14, and the other end of the tightening device is detachably installed to the side tube 3 through a hook. When cattle enter, the tightening rope is removed from one side of the side tube 3 via a buckle, making it easier for the cattle to enter between the top frame 1 and the bottom frame 2. After the cattle's neck is fixed by the vertical rod 6 and the inclined pins 9 on the inner and outer sides of the top frame 1, one end of the tightening rope is fixed to the side tube 3 via a buckle. Then, the length of the tightening rope is adjusted by shortening the rope length, and the side adjustment frame 113 is pulled to shorten the distance between the side adjustment frame 113 and the side tube 3, so as to achieve free adjustment and fixation of the cattle on both sides. At the same time, the tightening rope can limit the rear of the cattle.

[0033] The working principle of this utility model is as follows: Cattle are driven into the space between the top frame 1 and the bottom frame 2 from the rear side away from the crossbar 5. Multiple side tubes 3 and adjusting frames 113, fixedly connected to both sides of the top frame 1 and the bottom frame 2, limit the movement of the cattle on both sides. The crossbars 5 on the front sides of the top frame 1 and the bottom frame 2 are rotatably connected to the top frame 1 and the bottom frame 2 via corresponding rotating rods 4. When the crossbars 5 are in the inward-opening state, the cattle are driven into the space between the top frame 1 and the bottom frame 2, and move forward towards the top frame 1. The cattle's shoulders push the two vertical tubes 6 forward, causing the two crossbars 5 to gradually close. This causes the crossbars 5 to press against the inclined portion of the inclined pin 9 inside the top frame 1, thereby pulling the inclined pin 9 out of the sleeve 10. After the cow's head passes through the area between the two crossbars 5, the two crossbars 5 are completely closed. The inclined pin 9 on the inner side of the top frame 1 returns to the sleeve 10 under its own weight. The inclined pins 9 on the inner and outer sides of the top frame 1 abut against one side of each crossbar 5 to limit its movement, thereby limiting the cow's head movement. To ensure the synchronicity of the movement of the two crossbars 5, the inner side of each crossbar 5 near the top of the top frame 1 is fixedly connected to one end of the connecting block 16. When the vertical tube 6 at the bottom of one crossbar 5 comes into contact with the cow's body and moves, it drives the connecting block 16 to move. Through the transmission of the crank block 15 and the side mounting rod 14, the sliding sleeve 13 can slide along the outside of the sliding rod 12, thereby driving the connecting block 16 on the other side of the sliding sleeve 13 to move the other crossbar 5, thus performing a synchronous opening and closing process. An adjustment assembly 11 is also provided between the top frame 1 and the bottom frame 2. The adjustment assembly 11 includes a side adjustment frame 113 arranged parallel to the side tube 3. The top and bottom ends of the side adjustment frame 113 are rotatably connected to the corresponding horizontal plates 112, and the other ends of the horizontal plates 112 are hinged to the connecting seats 111 fixedly connected to the bottom end of the top frame 1 and the top end of the bottom frame 2, respectively. Thus, by pulling the side adjustment frame 113, the distance between the side adjustment frame 113 and the side tube 3 can be adjusted to fix the cattle on both sides in an adjustable manner. A tightening rope with a tensioner is provided on the rear side of the top frame 1 and the bottom frame 2 to tighten the rope. One end of the rope is fixed to the side mounting rod 14, while the other end of the rope tensioner is detachably installed to the side tube 3 via a hook. When the cattle enter, the tensioning rope is removed from one side of the side tube 3 via the hook, making it easier for the cattle to enter between the top frame 1 and the bottom frame 2. After the cattle's neck is fixed by the combined action of the vertical rod 6 and the diagonal pins 9 on the inner and outer sides of the top frame 1, one end of the tensioning rope is fixed to the side tube 3 via the hook. Then, the length of the tensioning rope of the rope tensioner is adjusted and the side adjustment frame 113 is pulled to shorten the distance between the side adjustment frame 113 and the side tube 3, so as to achieve free adjustment and fixation of the cattle on both sides. At the same time, the tensioning rope can limit the rear of the cattle. After the cattle have completed the restraint task, the outer connecting arm 8 of the top frame 1 is manually pressed down, so that the diagonal pins 9 on the outer side of the top frame 1 are pulled out of the outer insert 10 of the top frame 1. Then, the cattle are driven forward. The cattle's shoulders push the vertical tubes 6 on both sides forward, and the two horizontal bars 5 open outward without the obstruction of the outer diagonal pins 9, so as to release the cattle.Before the next repair, manually press the connecting arms 8 on both the inner and outer sides of the top frame 1 to pull the inclined pins 9 on both the inner and outer sides out of the sleeve 10, and then restore the two crossbars 5 to the inward opening position, waiting for the next repair work.
