Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pig slaughtering, in particular to a saddle type pig bleeding and conveying device and a conveying method. BACKGROUND

[0002] The saddle type pig bleeding and conveying device mainly conveys the pig by riding on the saddle type conveying chain. This conveying method makes the pig's hooves off the ground during transportation, and the pig cannot move during the whole transportation process. When the pig is conveyed to the end position, the worker can bind the pig's hind legs by the binding chain, and then scrape the hook on the binding chain to the conveying chain. The conveying chain will lift the pig, and then the pig can be bled and slaughtered in the subsequent process.

[0003] Chinese patent CN201721150692.3 discloses a specific conveying structure of the saddle type pig conveying machine, and most of the existing saddle type pig conveying machines adopt this structure. However, the following problems may occur during actual use. The conveying chain is located outside the left blocking frame 10. When the worker binds the pig by the binding chain, the pig's hooves need to be pried outwards after the binding is completed, and then the binding chain is hung on the conveying chain. The area where the binding chain contacts the pig's hooves will pass through the inclined avoidance gap 10b and be transported upwards. Since the length of the binding chain is constant, for a standard size pig, the area where the pig's hooves contact can pass through the inclined avoidance gap 10b and be transported upwards. However, if a relatively fat pig is mixed, the pig's hooves will become longer and fatter, which will cause the area where the binding chain contacts the pig's hooves to be lengthened downwards, and the length of the chain at the connection will be lengthened. This will cause the length of the binding chain to be insufficient, which will cause the pig's hooves to be squeezed by the upper limiting stop rod 10c, causing the pig to struggle excessively, and in severe cases, the pig's hooves may be broken. Due to this problem, the pig farm needs to control the size of the pig during breeding, and the pig needs to be sent to the market at the due date. However, due to the fluctuation of the pig price, the pig farm cannot adjust the time of sending the pig to the market according to the fluctuation of the pig price, which has a great impact on the factory.

[0004] Therefore, it is necessary to design a saddle type pig bleeding and conveying device and a conveying method, which can automatically adjust the height position of the upper limiting stop rod according to the size of the pig, so that the pig's hooves will not be squeezed by the limiting stop rod for a larger pig, ensuring the safe conveying. SUMMARY

[0005] In view of the above technical deficiencies, the purpose of the present application is to provide a saddle type pig bleeding and conveying device and a conveying method, which can automatically adjust the height position of the upper limiting stop rod according to the size of the pig, so that the pig's hooves will not be squeezed by the limiting stop rod for a larger pig, ensuring the safe conveying.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0034] Embodiment: The present application provides a saddle type live pig blood draining and conveying device and a conveying method, such as Figures 1-3As shown, including the saddle type conveying chain 1, pig pressing mechanism 2, blocking mechanism 4, elastic reset mechanism 5, inclined pulling mechanism 6, left blocking frame 10, right blocking frame 11 and two rows of side limiting mechanism 3, the saddle type conveying chain 1 is located in the middle of the left blocking frame 10 and the right blocking frame 11, the live pig will ride on the saddle type conveying chain 1, then, through the saddle type conveying chain 1 for conveying, will make the live pig on the saddle type conveying chain 1 transmission. The saddle type conveying chain 1 is fixedly provided with a driving motor and a sprocket transmission group for driving the saddle type conveying chain 1 to rotate. The left blocking frame 10 and the right blocking frame 11 are used for blocking and limiting the two sides of the live pig on the conventional equipment, two rows of side limiting mechanism 3 are respectively fixedly installed on the left blocking frame 10 and the right blocking frame 11, each row of side limiting mechanism 3 is a plurality of, a plurality of side limiting mechanism 3 are distributed in a row along the conveying direction of the saddle type conveying chain 1, the side limiting mechanism 3 is used for contacting and limiting the side of the live pig, the pig pressing mechanism 2 is located directly above the saddle type conveying chain 1, the pig pressing mechanism 2 is used for limiting the top of the live pig, the left blocking frame 10 is provided with a pig binding gap 10a, the top of the pig binding gap 10a is connected with an inclined avoiding gap 10b, the left blocking frame 10 is provided with an upper limiting stop rod 10c and a lower limiting stop plate 10d, the inclined avoiding gap 10b is composed of the gap between the upper limiting stop rod 10c and the lower limiting stop plate 10d, the lower limiting stop plate 10d is fixedly connected with the left blocking frame 10, the upper limiting stop rod 10c is fixedly installed on the elastic reset mechanism 5, the elastic reset mechanism 5 is used for pushing the upper limiting stop rod 10c to reset, the elastic reset mechanism 5 is fixedly installed on the left blocking frame 10, the inclined pulling mechanism 6 is fixedly installed on the left blocking frame 10, one end of the inclined pulling mechanism 6 is connected with the upper limiting stop rod 10c, the other end of the inclined pulling mechanism 6 is drivingly connected with the side limiting mechanism 3 at the end of the left blocking frame 10, the inclined pulling mechanism 6 is used for transmitting power of the side limiting mechanism 3 to the upper limiting stop rod 10c, when the live pig becomes wider, the live pig will push the side limiting mechanism 3 outward, the side limiting mechanism 3 drives the upper limiting stop rod 10c to incline upward through the inclined pulling mechanism 6. Conversely, when the live pig becomes smaller, the corresponding side limiting mechanism 3 will move inward.

[0035] First, the live pig rides on the saddle type conveying chain 1, then the live pig is conveyed through the saddle type conveying chain 1, and in the process of conveying the live pig, the side limiting mechanism 3 and the pig pressing mechanism 2 surround the live pig, and the side limiting mechanism 3 can be adjusted according to the size of the live pig. When the pig moves to the position about to be bound, the hind hoof will be exposed in the pig binding gap 10a. Then the worker binds the hoof and the chain at this position. If the live pig is obese and larger, the end side limiting mechanism 3 will be pushed outward, so that the inclined pulling mechanism 6 pulls the upper limiting stop rod 10c upward, so that the live pig with larger body type will not cause the hoof to be squeezed between the upper limiting stop rod 10c, ensuring the safe conveying.

[0036] Wherein, the blood draining roller conveyor 8 and the chain loop roller conveyor 9 are also included, after the live pig is slaughtered, it needs to be placed on the blood draining roller conveyor 8, so that the pig blood can be discharged downward, collected in the collecting box on the blood draining roller conveyor 8. Then it enters the chain loop roller conveyor 9, and the live pig after blood draining is lifted by the chain loop roller conveyor 9 and transported to the subsequent production line for processing.

[0037] The blocking mechanism 4 is fixedly installed on the left blocking frame 10, and is used to rotate and abut against the bottom of the upper limiting stop rod 10c, so that when the upper limiting stop rod 10c is pulled upward, the upper limiting stop rod 10c is blocked by the blocking mechanism 4 and cannot move downward, and during the process that the pig leg is pulled upward along the inclined avoidance gap 10b, the pig leg will push the blocking mechanism 4 to reset the rotation, so that the upper limiting stop rod 10c can be reset downward for positioning the lower pig. The main reason for supporting by the blocking mechanism 4 is that the position of the side limiting mechanism 3 cannot be in the side projection range of the inclined avoidance gap 10b, which leads to that when the pig leg moves to the inclined avoidance gap 10b, the side limiting mechanism 3 will be separated from the pig body, so that the upper limiting stop rod 10c will be lowered, resulting in that the previous lifting of the upper limiting stop rod 10c has no effect. In order to avoid the lowering of the upper limiting stop rod 10c, the blocking mechanism 4 needs to be supported.

[0038] In order to enable the side limiting mechanism 3 to drive the upper limiting stop rod 10c to tilt when facing the live pig that is too fat, as shown in Figure 4 , the inclined pulling mechanism 6 includes a rotating rod 6a, a hinged seat 6b and a hinged rod 6c, the hinged seat 6b is fixedly installed on the left blocking frame 10, the middle part of the rotating rod 6a is hinged to the hinged seat 6b, one end of the rotating rod 6a is in contact with the side limiting mechanism 3, the other end of the rotating rod 6a is hinged to one end of the hinged rod 6c, the other end of the hinged rod 6c is hinged to the upper limiting stop rod 10c, and the elastic reset mechanism 5 is fixedly installed on the left blocking frame 10, and the pushing part of the elastic reset mechanism 5 is fixedly connected with the upper limiting stop rod 10c. When the live pig is fat, the side limiting mechanism 3 moves horizontally outward, the side limiting mechanism 3 will push the rotating rod 6a to rotate along the hinged seat 6b, the rotating rod 6a will pull the upper limiting stop rod 10c upward through the hinged rod 6c, so that the upper limiting stop rod 10c moves upward, and the upper limiting stop rod 10c will push the elastic reset mechanism 5 to tilt upward. When the pig body is separated from the side limiting mechanism 3, the elastic reset mechanism 5 will push the upper limiting stop rod 10c to reset, that is, the inclined pulling mechanism 6 is also reset. In this way, automatic feedback adjustment between the pig body and the upper limiting stop rod 10c can be realized, so that this adjustment mode can be applied to pigs of various sizes.

[0039] It needs to be explained that in the prior art, why not directly increase the width of the inclined avoidance gap 10b to adapt to pigs of different sizes. The main reason is that in the case of a larger gap, the live pig will drill along the gap in a tense environment.

[0040] As shown in Figure 4 The elastic reset mechanism 5 includes two guide posts 5a and two push springs 5b. The ends of the two guide posts 5a are fixedly connected with the upper limit stop lever 10c, and the two guide posts 5a are slidingly connected with the left stop frame 10. The push spring 5b is sleeved on the guide post 5a, and the push spring 5b is used to provide an elastic force to the upper limit stop lever 10c away from the left stop frame 10. One end of the push spring 5b abuts against the left stop frame 10, and the other end of the push spring 5b abuts against the upper limit stop lever 10c. Through the elastic force of the push spring 5b, the upper limit stop lever 10c can be pushed downward, and when the upper limit stop lever 10c is pulled by the inclined pulling mechanism 6, the push spring 5b will be compressed.

[0041] If the upper limit stop lever 10c adopts a straight pipe structure, when the chain is pulled upward, the chain will have a probability of being stuck in the gap between the upper surface of the upper limit stop lever 10c and the left stop frame 10 body, causing the equipment to malfunction. In order to prevent the chain from being stuck between the upper limit stop lever 10c and the upper limit stop lever 10c after the position of the upper limit stop lever 10c changes, a bending portion is fixedly arranged on both sides of the upper limit stop lever 10c, and a lower stop lever 10e and an upper stop lever 10f are fixedly arranged on the left stop frame 10. The two bending portions respectively abut against the two lower stop levers 10e and the upper stop levers 10f. The contact area between the bending portion and the lower stop lever 10e or the upper stop lever 10f is a beveled structure, and the inclination direction of the beveled structure is parallel to the movement direction of the upper limit stop lever 10c. By arranging the bending portion on the upper limit stop lever 10c, and the opening direction of the bending portion being closed by the lower stop lever 10e and the upper stop lever 10f, the risk of the chain being stuck between the upper surface of the upper limit stop lever 10c and the left stop frame 10 body is avoided. During the inclined upward movement of the upper limit stop lever 10c, the bending portion will slide upward along the bevel of the lower stop lever 10e.

[0042] In order to prevent the upper limit stop lever 10c from falling when the side limit mechanism 3 is separated from the pig body, as shown in Figure 5As shown, the blocking mechanism 4 includes a rotating rod 4a, a torsion spring 4b and a hinge seat 4c, the hinge seat 4c is fixedly installed on the left blocking frame 10, the rotating rod 4a is rotatably installed on the hinge seat 4c, the torsion spring 4b is sleeved on the rotating shaft of the hinge seat 4c, and the torsion spring 4b is used to provide the rotating rod 4a with an elastic force close to the upper limiting stop rod 10c. The end of the rotating rod 4a is provided with a stepped notch 4a1, and the upper limiting stop rod 10c is provided with an extension 10s in contact with the stepped notch 4a1. The extension 10s is clamped with the stepped notch 4a1. By arranging the extension 10s, when the chain slides upward along the upper limiting stop rod 10c, it will not slide into the bottom of the upper stop rod 10f, avoiding the situation of being stuck. When the extension 10s is tilted and pulled, the torsion spring 4b will push the rotating rod 4a to move, so that the stepped notch 4a1 is clamped with the extension 10s, avoiding the situation that when the side limiting mechanism 3 is separated from the pig body, the upper limiting stop rod 10c will fall down.

[0043] In order to be able to clamp the pig body, and at the same time be able to push the inclined pulling mechanism 6 to move according to the pig body, as shown in Figure 6 and Figure 7 As shown, the side limiting mechanism 3 includes a contact plate 3a, a limiting plate 3d, two guide columns 3b and two contact springs 3c. The ends of the two guide columns 3b are fixedly connected with the contact plate 3a, and the two guide columns 3b are slidably connected with the left blocking frame 10. The limiting plate 3d is fixedly installed on the other end of the two guide columns 3b. The contact spring 3c is sleeved on the guide column 3b, and the contact spring 3c is used to provide the contact plate 3a with an elastic force towards the pig body. The limiting plate 3d is in contact with the rotating rod 1 6a. One end of the contact spring 3c is in contact with the left blocking frame 10, and the other end of the contact spring 3c is in contact with the contact plate 3a. The contact plate 3a is provided with a plurality of arc-shaped protrusions. When these arc-shaped protrusions are in contact with the pig, they can scrape off the dirt on the pig, and at the same time, they will not cause long-time contact friction with the pig skin, avoiding the pain of the pig. At the same time, when the pig is obese and pushes the contact plate 3a to move, the contact plate 3a will push the limiting plate 3d to move through the guide column 3b, so that the limiting plate 3d pushes the rotating rod 1 6a to move, that is, drives the upper limiting stop rod 10c to move upward and incline.

[0044] Because there is a difference in obesity between every two pigs, and if the initial contact position of the side limiting mechanism 3 is not adjusted, the side limiting mechanism 3 will have the situation of over-pressing the live pig or no pressing between the live pig. Therefore, as shown in Figure 8 and Figure 9As shown, the initial adjusting mechanism 7 is fixedly installed on the left blocking frame 10, and includes a connecting rod 7d, two nuts 7f, two studs 7e and a plurality of extrusion modules, each of which includes a trapezoidal push block 7a, a guide column three 7b and a guide seat 7c. The end of the trapezoidal push block 7a is inserted between the limiting plate 3d and the left blocking frame 10. The bottom of the guide column three 7b is fixedly connected with the trapezoidal push block 7a. The connecting rod 7d is fixedly connected with the top of the plurality of guide column threes 7b. The guide seat 7c is fixedly installed on the left blocking frame 10. The guide column three 7b is in sliding connection with the guide seat 7c. The two studs 7e are respectively installed on the two guide seats 7c at the two ends. The nut 7f is in meshing installation on the stud 7e. The bottom of the nut 7f is in contact with the top of the connecting rod 7d. When the initial position of the side limiting mechanism 3 needs to be adjusted, the nut 7f is rotated downward to push the connecting rod 7d downward, so that the trapezoidal push block 7a pushes the limiting plate 3d outward, that is, the limiting plate 3d pushes the contact plate 3a away from the pig body through the connecting action of the guide column two 3b, so as to adapt to the batch of pigs that are too fat, and vice versa.

[0045] As shown in the figure, Figure 2 The pig pressing mechanism 2 includes a pig pressing rod 2a and a plurality of connecting assemblies, each of which includes a screw rod two 2c, a cross beam 2d and two nuts two 2b. The cross beam 2d is fixedly installed between the left blocking frame 10 and the right blocking frame 11. The pig pressing rod 2a is fixedly connected with the bottom of the plurality of nuts two 2b. The screw rod two 2c passes through the cross beam 2d. The two nuts two 2b are in meshing installation on the screw rod two 2c. The two screw rods two 2c are clamped on the cross beam 2d. The pig pressing rod 2a limits the pig top of the pig to avoid the pig standing up. At the same time, the height of the pig pressing rod 2a can be adjusted through the action of the screw rod two 2c and the nut two 2b.

[0046] The delivery method of the saddle type pig blood delivery device includes the following steps:

[0047] Step one: adjust the height position of the pig pressing rod 2a by rotating the nut two 2b, and adjust the initial adjusting mechanism 7 at the same time, so that the width position of the contact plate 3a changes;

[0048] Step two: the pig rides on the saddle type delivery chain 1, and the pig is delivered through the saddle type delivery chain 1. The fat or thin pig is in extrusion and close contact with the contact plate 3a;

[0049] Step three: after the pig contacts with the contact plate 3a at the tail end, the contact plate 3a pushes the inclined pulling mechanism 6, so that the upper limiting block rod 10c is pulled upward. According to the different fatness of the pig, the height of the upward pulling of the upper limiting block rod 10c is different. At the same time, the blocking mechanism 4 rotates to resist the bottom of the upward limiting block rod 10c;

[0050] Step four: workers through the chain pig trotters tied, and then start the saddle type conveying chain 1 conveying a pig body distance, while the chain hooks and conveying chain hook, pig trotters will pass through the inclined gap 10b, while the pig trotters will push the rod two 4a clockwise rotation reset, the upper limit stop bar 10c down, the pig is finally lifted.

[0051] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
