Definitions

  • the present invention relates to artificial insemination devices for small animals and more particularly for backyard birds, called “machine guns” and which are of the type comprising, on the one hand, inside a housing, a cylindrical guide passage for seed ejection means, and, on the other hand, a seed reservoir tube connected by holding means to a part integral with said housing, said part projecting from the front face of the housing and being traversed by said passage, the reservoir tube and the holding means being located in front of the front face of the housing with the reservoir tube positioned coaxially with said passage and extending beyond the projecting part.
  • semen ejection means consist of a piston rod slidingly mounted in the passage of the housing and provided with step-by-step advance means
  • a machine gun makes it possible, from a given volume of semen (or other injected product) contained in the reservoir tube, to carry out several successive injection operations, each using only a given fraction or dose, known and perfectly determined, which thus authorizes the successive and immediate insemination of several animals .
  • the holding means are provided by the presence of a flexible protective sheath which envelops the assembly constituted by the reservoir tube and said projecting part and is fixed at its rear end to the latter, either by a clamping ring cooperating with a converging outer surface of this part, either by elasticity on a rib, for example spiral, provided on this same part, while at its front end, this sheath offers a convergent or rounded shape which serves as a stop at the end of the tank tube. This convergent or rounded shape on the one hand, facilitates penetration into the cesspool and on the other hand, avoids injuring the wall of the latter.
  • the reduced-size orifice which is delimited by this converging or rounded end plays an adjusting role and allows, under the effect of the mechanical force provided by the piston rod which penetrates into the reservoir tube, to evacuate the seed under pressure in the form of a jet, without forming a drop "beading at the end of the sheath and which, remaining fixed to the latter by capillary action, would be lost for insemination, thus causing on the one hand, an error in the dose actually injected and on the other hand, a higher cost of the operation due to the very high price of the semen.
  • a reservoir tube as described above has a capacity of approximately 0.5 cm 3 and therefore makes it possible to inseminate 20 to 25 animals taking into account the concentration of the ejaculate contained in this tube.
  • concentration must be different and the abovementioned capacity would only allow the obtaining of approximately 10 doses, which would require a far too frequent change of the tank tube and therefore a waste of time.
  • the cost of the reservoir tube also increases the cost price per dose injected.
  • the sheath generally made of polyvinyl chloride, like the reservoir tube, is also of a relatively high cost price and further burdens the cost of use.
  • the invention aims to eliminate these various drawbacks, firstly by reducing the cost price of the removable and replaceable part previously constituted by the reservoir tube and the sheath.
  • the subject of the invention is a device of the aforementioned type, characterized in that said means for holding the reservoir tube on the projecting part extend in line with the rear end of the reservoir tube, which rear end engages by interlocking on one of said holding means constituted by a bearing provided on the projecting part, in that said holding means comprise, in addition to said bearing, a part of a clamping piece allowing by wedging between itself and the bearing holding the rear end of the reservoir tube on the bearing, this clamping piece further having an elongated part which surrounds a limited part of the length of the reservoir tube, also in the region of the rear part of the latter, thus opposing significant deformations of the reservoir tube, and in that the front end of the reservoir tube has a convergent or rounded shape.
  • the preceding arrangement makes it possible to provide that the internal diameter of the reservoir tube is significantly greater than that of the cylindrical guide passage, and therefore at diameter of a piston rod constituting the seed injection means, which thus makes it possible to have tubes of a clearly greater capacity and which can for example also contain, 20 to 25 doses of seeds of the gallus species if this capacity reaches 1.2 cm 3 .
  • the projecting part integral with the housing has, externally and successively along the axis of the guide passage, the holding surface of the reservoir tube and a free cylindrical surface of diameter less than the internal diameter of the reservoir tube.
  • This cylindrical surface penetrates freely into the reservoir tube and more particularly serves as a support for a piston stopper which is normally provided at this end inside the tube and serves to eject the seed under the action of the piston rod .
  • This device is in the form of a pistol consisting of a housing 1 having a front face 1a in which is fixed a block 2 which has a barrel-shaped part 2a projecting from the face 1a and oriented along a direction XX.
  • This block 2 and its projecting part 2a have a cylindrical guide passage 3 arranged in the direction XX and inside which is slidably mounted a piston rod 4 which extends behind the block 2 inside the housing 1 and is provided with step-by-step feed means 5 which include pierced plates 5a, springs 5b and stops 5c and which will not be described in more detail, a description already being given in French patent no. 7,902,020.
  • These advance means 5 are controlled using a trigger gun 6 which projects through a stock 7 of the housing disposed laterally with respect to the axis XX.
  • the projecting part 2a of the block 2 comprises externally and successively from the face 1a of the housing and in the direction XX, a cylindrical surface having a fixing thread 8, then a cylindrical seat 9 of slightly smaller diameter, and, after a radial shoulder 10, a frustoconical convergent bearing surface at a relatively small angle 11 and finally a cylindrical surface 12 ending in a beveled end 13.
  • this gun With this gun is associated a reservoir tube or flake 14 made for example of polyvinyl chloride and which contains animal semen, its rear end being closed off with a plunger stopper 15.
  • the internal diameter of this flake is very slightly greater, with a clearance e, than the diameter of the cylindrical surface 12 of the barrel 2a.
  • Its extreme rear portion 14a is forcibly engaged, by interlocking, on the frustoconical surface 11 of the barrel, the flaring of this normally cylindrical end ensuring clear support on this part. It follows from this interlocking that the projecting barrel 2a penetrates inside the reservoir tube 14 and that its end 13 serves as a stop for the piston stopper 15.
  • a longitudinal slot can also advantageously be provided on the extreme rear fitting portion 14a, this slot having the function of facilitating, on the one hand, the fitting of the straw when it is placed on the barrel 2a of the pistol, and on the other hand, to also facilitate its ejection once it has been fully used.
  • the plug-piston 15 which has three parts juxtaposed in the axial direction, is colored in that of these parts which is located in the middle so that, when the plug reaches almost the front end 14b of the straw , this colored part serves as an optical signal for the inseminator who then knows that he is almost at the end of the continuous seed in the straw and that he has only two or three doses left to inseminate.
  • This cap allows, moreover, an easy and rapid aspiration of the liquid in the straw before mounting it on the gun, and this from a bulb containing the liquid (such as, for example, harvested cock seed , or any other liquid to be injected).
  • This assembly is completed by a clamping piece 16 of revolution and which successively comprises from the rear towards the front a connection part 16a provided with an internal thread which is screwed onto the thread 8 of the barrel, then a chambering 16b which leaves a certain clearance with respect to the range 9 and the shoulder 10 of this barrel, and an end portion 16c comprising an inner cylindrical bore of diameter very slightly greater, with a clearance e, 'than the outside diameter of the tube- reservoir 14, the rear edge of this bore having a rounding or fillet 16d which rests on the flared part 14a of the reservoir tube and on the frustoconical surface 11 of the barrel.
  • the rounded 16d which is polished, makes it possible to avoid sectioning of the reservoir tube 14 at this level and, consequently, an escape of the latter out of the gun during actuation of the rod. -piston 4.
  • the cylindrical front part 16c extends over a certain length around the reservoir tube 14 so as to reinforce the positioning and the rigidity of the latter, and the length of this guide can reach for example one third, half or even more than half the length of the tube 14.
  • This latter reservoir tube 14 has at its front end a frustoconical convergent part 14b which ends in a flange 14c folded internally in the form of a hem and which can even return axially towards the interior of the reservoir tube, this flange delimiting an orifice ejection 14d.
  • the inseminator can then introduce the tube 14 into the cesspool of the animal and, using the trigger 6; actuate the piston rod 4 which, via the plug 15, pushes the desired dose of semen through the orifice 14d of the straw, the throttling of the jet thus obtained promoting the quality of insemination.
  • the inseminator can replace the latter by dismantling and reassembling the clamping piece 16.
