Specific embodiment

The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.

Embodiment 1

Referring to Fig. 1, which includes cutter hub 1, and one end of cutter hub 1 is rotation connection end 101, and the other end is to crush end 102, multiple crushing tooths 103 are equipped on crushing end 102.Rotation connection end 101 is set by one end of cutter hub 1, one end is band There is the crushing end 102 of crushing tooth 103, cutter hub 1 can be rotatably installed on crushing unit by being rotatablely connected end 101, thus Material can be formed as scissors in crushing process and be sheared, while crushing tooth 103 increases connecing for crushing knife and raw material Contacting surface product, can greatly improve crush efficiency and crushing effect.

The two sides at the crushing end 102 in the present embodiment are symmetrically arranged with crushing tooth 103, after the crushing tooth 103 when side is worn, It is installed after cutter hub 1 being overturn, continues to crush using the crushing tooth 103 of the other side.It is opened on a side for crushing end 102 Rectangular recess equipped with multiple arranged in step shape, rectangular recess form the crushing of arranged in step shape on the side for crushing end 102 Tooth 103.The contact area of cutter hub 1 Yu material, Er Qiejia can be increased to greatest extent by the crushing tooth 103 of arranged in step shape Work is convenient, at low cost.

In order to guarantee the service life of crushing knife, the width that end 102 is preferably crushed in the present embodiment is greater than rotation connection end 101 width, and the thickness for crushing end 102 is greater than the thickness at rotation connection end 101.

Referring to fig. 2~4, the grinding device of the present embodiment includes crushing shell 8, crushing main shaft 2 and crushing knife, crushes main shaft 2 are rotatably arranged in crushing shell 8, crush and are fixed with fixed mechanism on main shaft 2, and the rotation connection end 101 of crushing knife, which rotates, to be connected Fixed mechanism is connect, and the rotary shaft of crushing knife is relative to the eccentric axis setting for crushing main shaft 2.

Specifically, the fixed mechanism in the present embodiment includes two fixed disks 3, fixed disk 3, which is coaxially fixed on, crushes main shaft 2 On, multiple blade shafts 4 are uniformly fixed between two neighboring fixed disk 3, the rotation connection end 101 of crushing knife is rotatably connected on knife On bobbin 4.The crushing end 102 of crushing knife is free end, and crush the cutter hub 1 of 2 upside of main shaft crushes end 102 in the effect of gravity Under fall on an adjacent blade shaft 4, the crushing knife for crushing the downside of main shaft 2 then freely hangs downwards under gravity.Phase Crushing knife on adjacent two blade shafts 4 is staggered, and can collide to avoid two crushing knifes in this way, improve making for crushing knife Use the service life.And fixed disk 3 also has the function of after protecting crushing knife, raw material to enter crushing unit, if without fixed disk 3, Raw material can be contacted directly with crushing knife, thus easily cause the case where crushing knife is by winding of raw stock, raw material in the present embodiment Due to the effect of blocking of fixed disk 3 after into crushing unit, raw material continues to convey from the surrounding of fixed disk 3, so raw material will not Close to the cutter axis 5 of crushing knife, thus effectively avoid playing the role of protecting crushing knife there is a situation where winding.

The present embodiment is equipped with multiple crushing knifes on each blade shaft 4, and a partition is additionally provided between two fixed disks 3 5, multiple crushing knifes on blade shaft 4 are divided into two groups by partition 5.When having multiple crushing knifes on blade shaft 4, crushing knife is being put It is easier to collide in dynamic process, crushing knife is be easy to cause to damage, crushing knife is divided by the present embodiment using partition 5 Two groups, every group of crushing knife only in the activity of the side of partition 5, thus effectively reduces crushing knife and collides there is a situation where mutual, Improve crushing knife service life.Blade shaft 4 in the present embodiment is equipped with 5~6 crushing knifes, and every side of partition 5 is equipped with 2~3 A crushing knife.

It crushes to be additionally provided on main shaft 2 and adjusts fan blade 6 and discharge blade 7, multiple discharge blades 7, which are fixed on, crushes main shaft 2 Rear end adjusts 6 axial position of fan blade and is adjustably arranged between fixed mechanism and discharge blade 7, crushes shell 8 and is equipped with and tune Save the corresponding oblique lining 9 of fan blade 6.By change adjust fan blade 6 crush main shaft 2 on position, thus change adjust fan blade 6 with The tiltedly gap of lining 9 adjusts the fineness of institute's comminuting matter.The outer side edges of fan blade 6 are adjusted from front to back gradually to close to crushing main shaft 2 Side inclination, adjust it is more accurate.

The rear upper side for crushing shell 8 is connected with material-pumping tube 10, and discharge blade 7 stirs smashed Chinese medicine after rotating upwards It is dynamic, then smashed Chinese medicine can be evacuated in next equipment using blower.The thickness at 7 both ends of discharge blade is consistent , but discharge blade 7 is greater than the width of the other end far from the width for crushing 2 one end of main shaft, can carry out to material better Agitation, conveying effect are more preferable.

Embodiment 2

Referring to Fig. 5, the present embodiment is solid on front side of the fixed disk 3 of feed end side on the basis of the grinding device of embodiment 1 Surely there is front apron 11, bear the impact that material enters crushing shell 8 using front apron 11, reduce the mill of fixed disk 3 and crushing knife Damage, and front apron 11 is set as being made of more than two gear Plate butt connections by the present embodiment, is on the inside of baffle body and powder The arc that broken main shaft 2 matches thus can easily disassemble front apron 11 from crushing main shaft 2, and will New front apron 11 is installed to again to be crushed on main shaft 2, easy access.

Although above having made detailed description to the utility model with generality explanation and specific embodiment, On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art 's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want Seek the range of protection.
