Description

Automatic grab pig hind leg device

Technical Field

The invention relates to the technical field of machinery, in particular to an automatic pig grabbing rear leg device.

Background

In daily life, the grasping pigs are required to be grasped when buying and selling the piglets or castrating the piglets. At present, the method for grasping the piglet mainly comprises the step of manually grasping the hind legs of the piglet by hands. When the catcher is close to the piglet, the piglet is easily frightened and runs around. The catching method easily causes labor waste and low efficiency, and hands of a catching person are easily injured by mistake in the process of catching the piglet. Therefore, the invention discloses an automatic pig grabbing rear leg device which can increase the distance between a catcher and a piglet and avoid the phenomenon that the catcher is scared and runs when the distance between the catcher and the piglet is too short to cause injury of the catcher.

Further: in order to increase the locking force of the lock catch, an inclination angle of 30-40 degrees is formed between the lock catch and the tangent line of the outer circular arc of the female half ring.

Further: the automatic pig rear leg grabbing device further comprises an adjusting knob and a fixed pulley, wherein the adjusting knob is installed at the handle end of the rack and is simultaneously connected with two take-up pulleys; the fixed pulleys are symmetrically arranged on two sides of the central line of the frame. One end of the steel wire rope is fixed on one take-up pulley of the adjusting knob, and the other end of the steel wire rope sequentially penetrates through the two fixed pulleys and the two wire guide wheels and then is wound on the other take-up pulley.

Further: the automatic pig rear leg grabbing device further comprises: the spring C, spring C totally two, each spring C installs between trapping apparatus and frame, and this spring C is in the use, and the elasticity that appears is the pulling force. When the adjusting knob is rotated clockwise, the two ends of the steel wire rope are recovered on the take-up pulley of the adjusting knob, the two catching devices are close to the middle, when the adjusting knob is rotated anticlockwise, the two ends of the steel wire rope are loosened from the take-up pulley of the adjusting knob, and the two catching devices move from the middle to the two sides under the action of the spring C.

The invention has the beneficial effects that:

1. the efficiency of catching the piglet is improved, avoid simultaneously catching the amazing of piglet to run caused by the too close distance of personnel and pig, cause the injury of catching personnel.

2. The user adjusts the distance between the two capturing devices according to the actual distance between the two rear feet of the piglet, and the piglet can be captured quickly by the user.
