Description

Flow-cutting axial-flow bale breaking, straw cutting and smashing integrated machine

Technical Field

The invention belongs to an integrated machine for chopping grass straws, breaking bales and cutting grass, and particularly relates to an integrated machine for chopping grass straws, breaking bales and cutting grass.

Background

The existing grass pulverizer can conveniently pulverize pasture and straws, but has the defects of one, more labor consumption and high labor intensity. The second disadvantage is that the fineness and the speed of the smashing can not be reached, the livestock can not eat the grass completely, the waste is too much, the third disadvantage is that the feed inlet is single, the bale with different shapes is limited, the fourth disadvantage is that the discharge outlet is also single, the grass is not easy to be discharged according to the requirements of the thickness and the fineness of the client, and the wet grass entering the straw is easy to block.

Disclosure of Invention

The invention aims to provide a flow-cutting axial-flow bale breaking, straw cutting and smashing integrated machine which is reasonable in structure and simple to operate, can complete axial-flow bale breaking, rope cutting, straw splitting and smashing at one time, improves smashing efficiency and effect, saves manpower, reduces labor intensity of workers, and improves safety performance.

The purpose of the invention is realized as follows: a shear flow axial flow bale breaking, straw cutting and crushing integrated machine comprises a shear flow straw cutting machine and an axial flow crusher which are arranged on a frame with wheels and pulled by a tractor, a first fine material outlet is arranged at the left lower part of a horizontal cylinder shell of the shear flow straw cutting machine, an adjustable feed inlet and a second fine material outlet are arranged at the upper part of the shell, a straw cutting roller is arranged in the shell through a bearing, a blade clamping flail knife is uniformly hinged on the straw cutting roller, a fixed tooth knife matched with the blade clamping flail knife is uniformly arranged on the inner wall of the shell, a chopper with a bale breaking spiral cone and a cutter wheel is arranged at the shaft end of the straw cutting roller extending out of one end inlet of the shell, the side inlet is connected with a feed channel, a foldable material supporting disc is hinged at the lower part of the other end of the shell, a discharge port arranged at the other end of the shell is connected with the feed inlet of the axial flow crusher through a material conveying channel, and a volute provided with a fan blade type movable blade and a hammer blade, the outer circumference of the impeller in the volute is provided with a replaceable screen or a rubbing plate matched with the outer end of the hammer sheet to form an inner ring, and a discharge channel between the inner ring and the volute and an outlet of the inner ring are communicated with a fourth fine material outlet at the upper part of the volute.

The invention can complete the procedures of axial flow bale breaking, rope cutting, grass chopping, flow cutting rubbing crushing, axial flow fine crushing and the like at one time, can break open the entering bale, cut off the binding rope, split and chop the straw, can also split and chop the entering long corn stalk, and can also be arranged on other grass mills for use, thereby not only improving the working efficiency and the effect of other grass mills, but also saving the labor and the labor intensity. The feed inlet with adjustable size has been designed, can close half with the feed inlet when smashing the little side bundle, can open the feed inlet when smashing big round bundle or scattering the grass, and little side bundle or scattering the grass can drop into with the fork, and big round bundle can be put into with fork truck, firstly saves the labour, secondly the people is far away from the machine relatively safer. Replaceable blade-clamping flail knives are uniformly distributed on the roller surface of the grass cutting roller, the blade-clamping flail knives can be made of scrapped band saw blades, the cost is low, the blade-clamping flail knives are sharp and durable, grinding is not needed, the grass cutting speed is high, and the four corners are available. The axial flow pulverizer, particularly the fan blade type movable cutter and the groove-shaped blades, not only can rapidly cut grass, but also can generate strong airflow to play a great role in sucking and discharging the grass.

When the forage grass or straw processing machine is used for processing forage grass or straw, the material supporting disc is firstly opened (the material supporting disc has two functions, namely, the material inlet which can be covered after being folded is a cover disc, and the material supporting disc with the supporting legs is opened). When the material supporting plate is opened and placed horizontally, then the power is input by a tractor or a motor, the mechanical rotation is carried out, when the rotation speed required by high speed is increased from low speed to high speed, the pre-placed straw bundle on the material supporting plate is pushed into a chopper, under the action of the chopper, the straw bundle is firstly screwed into and broken by a rotating bale breaking screw cone, when the straw bundle enters a tooth-shaped cutting knife, the straw bundle rope is cut off by the rotating tooth-shaped cutting knife, then the cut straw rope is drawn off by hands, the straw also continuously enters inwards at this time, the transversely entering straw is cut off by the tooth-shaped cutting knife, the thick straw which enters along is split by the tooth-shaped cutting knife, then the straw enters into a movable blade type cutter to be cut off and automatically sent into a flow cutting machine, (the straw can be discharged from a first fine material outlet according to the requirement of a client), and is sucked by an axial flow crusher after being kneaded and crushed by the flow cutting machine (can also be discharged from a second fine material outlet according to the requirement of the client), under the action of the axial flow crusher, grass entering a little longer part is cut up by the movable blades of the axial flow crusher, is delivered to the hammer blades to be crushed and then is discharged from the third fine material outlet or the fourth fine material outlet through the screen or the kneading plate. If the kneading plate is replaced, it is discharged directly from the fourth fines outlet. If round bales of grass or loose grass can directly use the feed inlet with adjustable size above the flow-cutting hay cutter, the feed inlet with adjustable size is completely opened, then the foldable material supporting disc is folded to close the feed inlet of the chopper, and then the forage with the rope drawn out is put into the chopper by using a fork or a fork-type hay forklift. The grass chopping machine is characterized in that a blade clamping flail knife of the flow cutting grass chopper is matched with a fixed tooth knife inside a shell to be rapidly and roughly cut, then the grass is sucked into an axial flow crusher through a material conveying channel, the material conveying channel is arranged at the position of the material conveying channel and is matched with a fan blade type movable knife on the axial flow crusher to rapidly chop a little bit of grass again, then the chopped grass is smashed again through a hammer slice and is discharged from a fourth fine material outlet through a screen or a rubbing plate, and the smashing process can be completed. The customers can also select freely from 4 fine material outlets according to the thickness requirements of the customers. Therefore, the invention can complete the procedures of' bundle breaking, rope cutting, grass chopping, kneading and crushing of the tangential flow grass cutter, axial flow, chopping, kneading, crushing and the like at one time. Through three times of kneading and crushing, the straws can achieve the effect of fine kneading, and livestock like eating and not wasting, so the invention not only improves the crushing effect and efficiency, but also improves the safety, reduces the labor and the labor intensity, and has simple design structure and convenient operation and maintenance.

The axial-flow straw chopping machine is reasonable in structure and simple to operate, axial-flow bundle breaking, rope cutting, straw chopping and chopping are completed at one time, the chopping efficiency and effect are improved, manpower is saved, the labor intensity of workers is reduced, and the safety performance is improved.
