The fifth elastic element is a pressure spring 601, and the pressure spring 601 is fixedly disposed between the pressure plate 600 and the base 602.
With the above embodiments, the usage principle and the working process of the present invention are as follows:
during operation, the pigs that need to be slaughtered or the pigs that are sick are driven to the pig cage 700, the motor 100 is started, the pig cage 700 is clamped through the clamping mechanism, danger caused by shaking of the pigs in the pig cage 700 is reduced, and the pig cage 700 is lifted to the height of the container, and then the pig cage 700 is opened to drive the pigs.
In an initial state, when a pig does not drive into the pig cage 700, the steel rope 102 is in a loose state, the driving plate 300 is positioned at the upper part of the bracket 200 under the action of the return spring 301, the stop block 400 is positioned in a horizontal second state under the action of the fourth spring 401, the first rack 501 and the second rack 502 sleeved on the transmission rod 405 are positioned at the farthest distance, the first spring 507 and the second spring 514 of the clamping mechanism are positioned at the original length, and the compressed spring 601 is also positioned at the original length.
When driving the pig to pig cage 700 in, because the quality of pig is great, make pressure spring 601 take place deformation through clamp plate 600, along with the deformation of pressure spring 601, clamp plate 600 slides down along support 200 gradually, fixed first buffering rack 605 that sets up on clamp plate 600 moves down, make simultaneously and rotate with the buffering gear 607 of first buffering rack 605 meshing, drive the second buffering rack 606 with buffering gear 607 meshing and upwards slide, because second buffering rack 606 upper end and slider 511 fixed connection, when second buffering rack 606 upwards slides, promote slider 511 and upwards slide along the spout. The sliding block 511 of the first transmission assembly is provided with a rotatable gear column 500, and the gear column 500 and the sliding block 511 synchronously move upwards along with the sliding block 511 sliding upwards along the sliding groove. The greater the mass of the pig, the greater the distance the gear column 500 moves upwards to cause the first rack 501 to engage the gear column 500 earlier during the downward movement of the drive plate 300.
At this time, the motor 100 is started, the steel rope 102 is gradually tightened, but the pig cage 700 is not lifted, the pulley 202 arranged on the drive plate 300 is driven to rotate for a fixed angle and then slide in the tightening process of the steel rope 102, the pulley 202 is fixedly connected with the rotating shaft arranged on the drive plate 300, the rotating shaft is connected with one end of the stop block 400 in a winding manner through the flexible rope 402, and the stop block 400 is rotated to a vertical first state when the rotating shaft rotates. Because the middle part of the stop 400 is fixedly connected with the transmission rod 405, the transmission rod 405 rotates by a fixed angle, and simultaneously the first rack 501 in threaded connection with the transmission rod 405 slides for a certain distance along the transmission, at the moment, the distance between the first rack 501 and the second rack 502 is reduced, the position of the first rack 501 after moving can be just meshed with the gear column 500, and the second rack 502 can not be meshed with the gear column 500 under the control of the limit screw 509.
When the steel cable 102 is gradually tightened, the force of the steel cable 102 acting on the driving plate 300 is gradually increased and is greater than the pulling force of the return spring 301, the driving plate 300 slides downwards along the bracket 200, and the first rack 501 is meshed with the gear column 500 and drives the gear column 500 to rotate along with the downward sliding of the driving plate 300. When the gear column 500 rotates, the first toothed bar 503 and the second toothed bar 504 engaged with the gear column 500 move relatively, the first pushing plate 505 and the second pushing plate 512 fixedly connected with the first toothed bar 503 and the second toothed bar 504 respectively approach to each other, the first pushing plate 505 and the second pushing plate 512 respectively slide along the directions of the first guide rod and the second guide rod, and simultaneously, the first spring 507 and the second spring 514 are compressed to act on the first baffle 506 and the second baffle 513, so that the first baffle 506 and the second baffle 513 approach to each other and abut against the pig cage 700, and the pig cage 700 is gradually clamped. According to the fact that the larger the mass of the pigs placed in the pig cage 700, the more the second buffer rack 606 of the buffer assembly pushes the gear column 500 to move upwards, the earlier the first rack 501 is meshed with the gear column 500 in the process that the driving plate 300 moves downwards, and therefore the clamping mechanism clamps the pig cage 700 in advance. When the driving plate 300 continues to move downwards, the limit screw 509 is meshed with the fixed rack 510 on the bracket 200, the driving plate 300 moves downwards to drive the limit screw 509 to rotate, so that the second rack 502 screwed with the limit screw 509 slides along the transmission rod 405, and the position of the second rack 502 is gradually not limited by the limit screw 509. With the motor 100 driving the winch 101 to continue rotating, the steel rope 102 pulls the pig cage 700 to move upwards, the first clamping assembly and the second clamping assembly slide upwards synchronously, and due to the fact that the buffer rods 603 are arranged on the side walls of the first pushing plate 505 and the second pushing plate 512, when the first pushing plate 505 and the second pushing plate 512 move upwards, the buffer springs 604 are gradually compressed until the base 602 is pulled to move upwards synchronously, and when the base 602 moves upwards to a required position, the motor 100 is stopped to drive.
When the pig cage 700 is pulled by the steel rope 102 to ascend, for example, when the steel rope 102 is broken or the winch 101 is damaged, the pig cage 700 descends rapidly under the action of gravity, at this time, the driving plate 300 and the pulley 202 are no longer under the downward acting force of the steel rope 102, meanwhile, the rotating shaft and the stopper 400 are wound and connected by the flexible rope 402 and are no longer under the force, the stopper 400 rotates rapidly under the action of the fourth spring 401 to a horizontal second state, at the same time, the driving rod 405 is driven to rotate, the first rack 501 slides along the driving rod 405, the first rack 501 is disengaged from the gear column 500, the pig cage 700 and the first driving assembly move synchronously downwards under the action of gravity, at this time, the second rack 502 is engaged with the gear column 500, the gear column 500 is driven to rotate in the same direction again, the first rack 503 and the second rack 504 are continuously driven to move relatively, and the first pushing plate 505 and the second pushing plate 512 fixedly connected with the first rack 503 and the second rack 504 respectively approach each other, the first spring 507 and the second spring 514 are further compressed, the pig cage 700 is further clamped, the pig cage 700 is gradually slowed down in the falling process until the first spring 507 and the second spring 514 are compressed to limit positions, the first clamping assembly and the second clamping assembly cannot be close to each other, the gear column 500 does not rotate when being meshed with the second rack 502, the pig cage 700 completely stops sliding along the support 200, the pig is prevented from being damaged due to the fact that the pig falls off quickly, property loss is caused, and meanwhile damage of workers in the operation process is avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
