Description

Pod breaking mechanism in pod removing machine

Technical Field

The invention belongs to the technical field of agricultural machinery, and relates to a pod breaking mechanism in a pod removing machine.

Background

When most beans crops reaped through the harvester, only collect the pod of parcel by beans because fresh pod is difficult to peel, through drying in the sun to it, strike the pod, make the pod fried open, then separate pod skin and beans, because the beans lead to the beans impaired at knocking the overweight that causes very easily in the process of knocking, after all pod skin is also relatively hard, accumulational pod always has some pod to be in the extreme state of china at knocking the in-process, can not hit broken pod skin or pod and beans all to damage promptly, cause the reason of this kind of problem to lie in: the sizes of beans are different, the sizes of pods are different, the stacking states, the positions and the like of the pods during pod breaking are different, and the problem of breaking the pods to take the beans with high efficiency and high quality is always solved.

Disclosure of Invention

The invention aims to provide a pod breaking mechanism in a pod removing machine aiming at the problems in the prior art, and the technical problem to be solved by the invention is to efficiently knock pods and avoid the pods from being knocked missing.

The purpose of the invention can be realized by the following technical scheme: the pod breaking mechanism in the pod removing machine is characterized by comprising a throat channel with a rectangular cross section, wherein the middle of the throat channel is rotatably connected with a plurality of rotating shafts which are parallel to each other, the middle distance between every two adjacent rotating shafts is equal, the rotating shafts are transversely arranged, the rotating shafts are fixedly connected with the middle of a rectangular mounting frame, two ends of the mounting frame are respectively provided with a knocking component, the two knocking components are symmetrically distributed on the upper side and the lower side of the rotating shafts, each knocking component comprises two limiting rods and a knocking block, the two limiting rods are fixed on the mounting frame and are perpendicular to the rotating shafts, two limiting holes corresponding to the two limiting rods are formed in the knocking block, and the limiting holes allow the knocking blocks to move on the limiting rods along the axial direction of the rotating shafts; one end of each rotating shaft extending out of the throat is fixedly provided with a transmission gear, the transmission gears on the adjacent rotating shafts are meshed with each other, and one rotating shaft is controlled by a driving mechanism driving the mounting frame to swing back and forth in a 30-degree angle range around the rotating shaft.

The bean pod removing machine is ingeniously characterized in that: through the installing frame that equidistant setting, the normal running fit of each pivot of cooperation, make pharynx way entry and export form the alternative respectively and open or close "keep silent", particularly, when two pieces of knocking of pharynx way entry are close to each other, two pieces of knocking that are in pharynx way export on same installing frame with these two pieces are in "opening" the body, vice versa with the reason, at the reciprocal wobbling in-process of one of them installing frame, each installing frame is synchronous to cooperate, make pharynx way entry and exit form respectively that a plurality of is in the unit of knocking of the state and the unit of knocking that is in the unloading state, and two states of knocking the unit in same vertical space region are opposite, such benefit is: pods entering from the pharyngeal entrance cannot exit the pharyngeal exit without being knocked, and there is an opportunity for all pods to be knocked by two knocking units at the pharyngeal entrance and exit. Moreover, under the certain circumstances of installing frame oscillating frequency, the quantity of the pod that goes into the hopper and get into can not influence the quantity that the pod discharged the throat way, makes the unloading in-process pod pile up the jam or the omission condition that causes improve greatly.

In foretell broken pod mechanism in going pod machine, actuating mechanism includes driving motor, drive gear, little swing arm, big swing arm and rocker, the drive gear meshing of the drive gear in drive gear and the frame outside, the axis department at drive gear is fixed to the one end of rocker, the other end of rocker is articulated with the one end of big swing arm, the other end of big swing arm is articulated with the one end of little swing arm, the other end of little swing arm links to each other with driving motor's output shaft is fixed.

The small swing arm rotates, the small swing arm, the large swing arm and the rocker form a connecting rod mechanism, the rocker swings in a reciprocating mode, the driving gear is driven to rotate in a reciprocating mode within a certain angle, each transmission gear is synchronous with the transmission gear, and the rotation directions of the adjacent transmission gears are opposite.

In foretell broken pod mechanism among the pod machine that goes, the fixed a plurality of stirring wheels that are provided with in the pivot, have the clearance between the adjacent stirring wheel in same pivot, adjacent epaxial stirring wheel alternate distribution that rotates, circumference evenly distributed has a plurality of stirring pieces on the stirring wheel.

The pod strikes the back once through once, gets into between two units of striking, through the swing of stirring wheel to and the interlock effect of adjacent stirring wheel, makes and is turned over by the material that once strikes and stirs, so that can improve broken pod probability with the atress condition of trading the pod as far as when strikeing once more, reduce the impaired probability of beans.

In the pod breaking mechanism in the pod removing machine, the limiting hole at one end of the knocking block, which is far away from the rotating shaft, is in the shape of an isosceles triangle, and the two isosceles sides are respectively positioned at the two sides of the knocking block; the knocking block is made of rubber.

Because the motion amplitude of the knocking block far away from one end of the rotating shaft is large, if the knocking block is uniform in mass distribution, the inertial force of one end, far away from the rotating shaft, of the knocking block is large, so that the knocking force of the two knocking blocks on bean pods at different positions is different when the two knocking blocks are combined, the shape of the limiting hole in the outer end of the knocking block is set in order to avoid the situation, the uneven influence of the inertial force is compensated in a hollowing mode, meanwhile, the elasticity of the knocking block during combined impact is improved, and the acting force on beans during knocking is relieved.
