Description
Technical Field
The utility model relates to the technical field of agricultural production appliances, in particular to a movable and fixed combined straw smashing mechanism.
Background
The straw crusher is mainly used for chopping crop straws, plant straws with branch diameters of less than 5CM and the like, and can also be used for chopping various crop straws and pasture. The straw crushing is carried out on the harvested crops by using the crusher, and the crushed straws are thrown in the farmland, so that the pollution of farmland incineration to the environment is avoided, and the effect of improving the soil structure and increasing the soil fertility is achieved.
And the rubbing crusher of current straw rubbing crusher constructs mostly the unipolar and smashes, can only smash the straw on the ridge peak, can't smash the straw in the furrow, and kibbling effect is relatively poor. The required crushing effect can be achieved only by secondary crushing, so that the workload is increased, and the production cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a move and decide convolution straw rubbing crusher and construct is provided, and one-time operation can reach the regrinding, improves crushing effect.
In order to solve the technical problem, the utility model adopts the following technical proposal.
The movable-fixed combined straw crushing mechanism comprises a fixed seat, wherein a connecting plate for connecting the fixed seat to a machine is arranged at the front end of the fixed seat, and a front cutter shaft for crushing straws is arranged below the fixed seat; a rear cutter shaft used for secondarily crushing the crushed straws is arranged behind the front cutter shaft through a rear cutter shaft base, a front cutter is arranged on the front cutter shaft, a rear cutter is arranged on the rear cutter shaft, and a fixed cutter used for crushing the straws and throwing the straws is arranged on the rear cutter shaft base below the rear cutter shaft; a discharge hole for throwing the crushed straws is formed above the rear cutter shaft base; and a ground roller for limiting the depth of the crushed straws is arranged behind the rear cutter shaft base.
The movable-fixed combined straw smashing mechanism is characterized in that the front cutter comprises a plurality of short cutters arranged on the front cutter shaft and used for smashing straws and a long cutter used for picking up and smashing the straws in the furrow.
Above-mentioned move and decide convolution straw rubbing crusher structure, the top of discharge gate is provided with the guide plate that is used for exporting the straw after smashing.
The movable-fixed combined straw smashing mechanism is characterized in that a soil retaining plate for preventing dust from rising is arranged at the bottom end of the fixed seat in front of the front cutter shaft.
Due to the adoption of the technical scheme, the utility model has the following technical progress.
The utility model discloses set up long and short sword in the front on the arbor, not only can smash the straw on the ridge peak, can also pick up and smash the straw in the furrow, the back sword adopts to move stationary knife alternately, has played the effect that regrinding and shed, has improved kibbling effect.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the front knife of the present invention;
wherein: 1. the device comprises a fixed seat, 2 parts of a front cutter shaft, 3 parts of a short cutter, 4 parts of a long cutter, 5 parts of a rear cutter shaft, 6 parts of a rear cutter, 7 parts of a rear cutter shaft base, 8 parts of a fixed cutter, 9 parts of a guide plate, 10 parts of a ground roller, 11 parts of a soil retaining plate and 12 parts of a connecting plate.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The structure of the movable-fixed combined straw smashing mechanism is shown in the figure 1-2, and the movable-fixed combined straw smashing mechanism comprises a fixed seat 1, wherein a connecting plate 12 is arranged at the front end of the fixed seat 1 and used for connecting the fixed seat to a machine.
The front cutter shaft 2 and the rear cutter shaft 5 are arranged below the fixing seat 1, the rear cutter shaft 5 is arranged behind the front cutter shaft 2 through the rear cutter shaft base 7, and the rear cutter shaft 5 performs secondary crushing on straws crushed by the front cutter shaft 2 to improve the crushing effect.
Be provided with a plurality of short sword 3 and long sword 4 on the preceding arbor 2, short sword 3 is used for smashing the straw, and long sword 4 is used for picking up and smashing the straw in the furrow, adopts the form that long sword and short sword combine, picks up the straw in the furrow and smashes, has improved kibbling effect.
The bottom of the fixing base 1 in front of the front cutter shaft 2 is provided with a soil retaining plate 11 to prevent dust generated in the straw crushing process from rising.
The rear cutter shaft 5 is provided with a rear cutter 6 for secondarily crushing the crushed straw by the short cutter, a rear cutter shaft base 7 below the rear cutter shaft 5 is provided with a fixed cutter 8 for secondarily crushing the crushed straw and throwing the crushed straw, and the rear cutter shaft is crossed by the movable cutter and the fixed cutter, so that the secondary crushing and throwing effects are achieved, and the crushed straw is thrown.
A discharge hole is arranged above the rear cutter shaft base 7 and used for throwing out the crushed straws, a guide plate 9 is arranged above the discharge hole, and the straws thrown out by the rear cutter shaft fall on the ground behind the straw crusher under the action of the guide plate.
The rear of back arbor base 7 is provided with ground roller 10 for the straw after the roll extrusion is smashed plays the effect of limit for depth to the straw after smashing, and the machine of being convenient for gets into the field and carries out follow-up operation.
The utility model discloses when carrying out the straw and smashing, the ground and the interior straw of furrow are through preceding arbor smash the back, go on further smashing through the back arbor, because what back arbor adopted moves the criss-cross design of stationary knife, shed away in discharge gate department behind the straw regrinding, and the straw of shedding away carries out the roll extrusion through the ground roller, conveniently carries out subsequent operation.
