Because pan feeding hole 8 is trapezoidal through-hole for when the straw passed through pan feeding hole 8 and got into the inside of main part 1, the straw can be gathered together towards the centre in-process in the inside of getting into main part 1 in unison, makes the in-process that feed port 2 inside blade 16 cut apart the straw, the stability of straw.
A recycling box 28 is fixedly arranged on the front wall surface of the main body 1 corresponding to the position of the discharge hole 27, the recycling box 28 is of a hollow rectangular structure, and the upper wall surface of the recycling box 28 is hollow.
The collecting hole 31 is a rectangular through hole, the collecting box 30 is of an internal hollow rectangular structure, the upper wall surface of the collecting box 30 is hollow, the shape and size of the collecting box 30 are matched with the shape and size of the internal part of the collecting hole 31, and the collecting box 30 penetrates through the collecting hole 31 to reach the inside of the main body 1 and vertically corresponds to the filter screen 22.
The straw scraps after the processing is finished can be collected through the collecting box 30 in the main body 1, after all the straws are crushed, the workers can take out the collecting box 30 from the collecting hole 31, the straws in the collecting box 30 are uniformly treated, and the treatment efficiency of the straw scraps is greatly improved.
The water injection block 9 of the supporting plate 3 is a rectangular through hole, and the material return hole 29 and the crushing device 21 are mutually corresponding up and down.
When using, the inside of main part 1 can be discharged through relief hole 27 to unqualified straw piece to fall into the inside of collection box 28, the staff can carry out the regrinding with the inside straw piece of collection box 28 through the inside that returns material hole 29 and drop into main part 1 again afterwards, thereby improves the crushing effect of this equipment to the straw greatly.
Principle of operation
When using, put into the inside of main part 1 through pan feeding hole 8 with the straw, then fall on filter screen 22 after reducing mechanism 21 shredding, when the straw after smashing falls on filter screen 22, receive the inside downstream of filter screen 22 drive extension piece 24 at shake groove 23 of gravity influence, extension piece 24 can drive magnet 25 downstream when moving down, because magnet 25 and magnet 26 are homopolar magnet, magnet homopolar repulsion's principle can meet one when magnet 25 is being close to magnet 26 in-process and has encountered the repellent and upwards held up magnet 25, so reach the effect of filter screen 22 shake repeatedly, make the qualified straw of smashing on the filter screen 22 fall into the inside of collecting box 30 through filter screen 22 and collect, unqualified then discharges through relief hole 27, thereby the practicality of agricultural straw rubbing crusher has been improved.
Carry out the water injection through water injection hole 11 to the inside of water injection piece 9 earlier when using, when the straw got into main part 1 inside through pan feeding hole 8, the last wall of straw can with the water injection sponge 10 contact extrusion on the water injection piece 9, water injection sponge 10 is after the extrusion that receives the straw, can paint the surface at the straw with the inside water of water injection piece 9, thereby make the in-process of the crushing straw at reducing mechanism 21, can not be because the straw too dry inside piece of main part 1 that leads to scatters everywhere, and then influence the operation of the inside precision component of main part 1.
When the straws enter the feeding hole 2 through the feeding hole 8, the driving motor II 19 is started to drive the cam 20 to rotate, when the narrow end of the cam 20 faces downwards, the cam 20 can downwards extrude the extrusion block 18, the extrusion block 18 drives the connecting plate 14 to downwards move, at the moment, the first spring 15 is stressed to deform, the connecting plate 14 drives the blade 16 to downwards move and cut the straws inside the feeding hole 8, when the narrow end of the cam 20 faces upwards, the cam 20 does not extrude the extrusion block 18, at the moment, the first spring 15 is restored to deform to drive the connecting plate 14 to upwards move, the connecting plate 14 drives the blade 16 to be re-collected into the dividing groove 12, the aim of equally dividing the straws entering the main body 1 through the feeding hole 8 is repeatedly achieved, and the problem that the straws are too long and difficult to crush is avoided.
When using, the inside of main part 1 can be discharged through relief hole 27 to unqualified straw piece to fall into the inside of collection box 28, the staff can carry out the regrinding with the inside straw piece of collection box 28 through the inside that returns material hole 29 and drop into main part 1 again afterwards, thereby improves the crushing effect of this equipment to the straw greatly.
When the straws are fed into the main body 1 through the feeding hole 8, the rotating roller 4 in the rotating groove 5 can be driven to rotate anticlockwise by starting the driving motor one 6, and the roughness of the outer wall surface of the rotating roller 4 is three hundred meshes, so that the friction force between the rotating roller 4 and the straws is improved, the effect of quickly feeding the straws into the main body 1 is achieved, and the working efficiency is improved.
The straw scraps after the processing is finished can be collected through the collecting box 30 in the main body 1, after all the straws are crushed, the workers can take out the collecting box 30 from the collecting hole 31, the straws in the collecting box 30 are uniformly treated, and the treatment efficiency of the straw scraps is greatly improved.
Because pan feeding hole 8 is trapezoidal through-hole for when the straw passed through pan feeding hole 8 and got into the inside of main part 1, the straw can be gathered together towards the centre in-process in the inside of getting into main part 1 in unison, makes the in-process that feed port 2 inside blade 16 cut apart the straw, the stability of straw.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
