Abstract
The invention discloses a hollow shaft grinder belonging to the technical field of agricultural mechanical equipment and solving the problems of small air quantity of a grinder during grinding, dead angle near a shaft center part during the grinding, low efficiency, and the like in the prior art. The hollow shaft grinder comprises a main shaft, a grinding part and a base body part, wherein the main shaft is arranged on the base body part; the grinding part is sleeved on the main shaft; the main shaft is a hollow shaft; and holes are distributed on the connecting part of the main shaft and the grinding part. Compared with the prior art, the hollow shaft grinder disclosed by the invention has the advantages of capabilities of obtaining sufficient air quantity and saving raw materials, higher efficiency, and the like; in addition the hollow shaft grinder has the advantages that grinding ventilation is good, grains are not attached to a screen so as to be not stored in an outer cavity of the screen, and grinding materials are not attached to a bag so as to enter the tail end of the bag.
Description
Technical field
The invention belongs to the agricultural machinery equipment technical field, more particularly, belong to a kind of pulverizer that is used to pulverize crops such as paddy.
Background technology
Pulverizer is an imperative equipment during modern agriculture is produced.Pulverizer of the prior art mainly comprises main shaft portion, pulverizes part, body portion, receipts grain part.Main shaft portion is installed on the body portion, and main shaft is installed on the bearing block of body portion by bearing.Because main shaft all is a solid shafting in the prior art, so there is certain problem in it; The air quantity of pulverizing partial interior during pulverizer work is little, and pulverizing near main shaft portion has the dead angle, pulverizes the section of part and can not effectively pulverize the pulverizer inefficiency to the grain material at this position.
Summary of the invention
The present invention provides a kind of hollow shaft pulverizer in order to solve above technical problem.
A kind of hollow shaft pulverizer of the present invention comprises main shaft, pulverizes part, body portion, and main shaft is installed on the body portion, pulverizes part and is sleeved on the main shaft; It is characterized in that main shaft is a hollow shaft, main shaft with pulverize the position that part links to each other on distribution porose.
By engineering mechanics knowledge as can be known, the intensity of same diameter hollow shaft is greater than the intensity of same diameter solid shafting, though have certain circular hole on the main shaft of hollow shaft pulverizer of the present invention, still can satisfy the shear strength requirement of main shaft, so can meet the demands fully during its work.Because hollow shaft quality of the present invention is a lot of than the solid shafting light weight, so it can save material.
Two ports that hollow shaft pulverizer of the present invention can pass through hollow shaft so just can obtain enough intakes to the inside of pulverizer air intake, can obtain better machining effect.No dead angle in the pulverizer by center wind-force effect, makes the faster generation centrifugal force of crushed material during pulverizing, arrives to pulverize optimal site.During pulverizing, inner chamber can make and pulverize the back particle and fly out rapidly outside the sieve under the wind-force effect of center, makes the operating efficiency of pulverizer improve 15 ~ 20%, has obtained better technical effect.The air quantity of inside is little when efficiently solving the work of traditional pulverizer, and pulverizing near the spindle axis place has problems such as dead angle, pulverizer inefficiency.
The present invention compared with prior art has: obtained enough intakes, saved raw material, efficient is than advantages such as height.Pulverize and breathe freely, not protect sieve, sieve the exocoel thing of not storing up grain; Do not protect bag, can make crushed material enter the cloth bag end.

Accompanying drawing 1 is the structural representation of hollow shaft pulverizer of the present invention;
Accompanying drawing 2 is side views of hollow shaft pulverizer of the present invention.
The specific embodiment
Fig. 1 is the structural representation of hollow shaft pulverizer of the present invention; Hollow shaft pulverizer of the present invention comprises main shaft, pulverizes part, body portion, and main shaft is installed on the body portion, pulverizes part and is sleeved on the main shaft; Main shaft 1 is a hollow shaft, main shaft 1 with pulverize the position that part links to each other on distribution porose.Hollow shaft pulverizer of the present invention comprises main shaft 1, left end bearing 3, bearing 4, oil filler point 5, first key 6, bolt 8, right-hand member bearing 9, spacer 10, second key 11, belt pulley 12, section 13, slices holder 14, bearing pin 15, cabin spacer 16, movable spacer 17.
Three slices holder 14 are installed on the main shaft 1, and slices holder 14 is welded on main shaft 1; Section 13 is installed on the slices holder 14 by bearing pin 15, and four bearing pins 15 have been installed altogether on the slices holder 14, and being installed in has movable spacer 17 between the section 13 on the bearing pin 15; Cabin spacer 16 is arranged between the slices holder 14, and a long side weld of cabin spacer 16 is connected on the main shaft 1, two broadsides are welded on the slices holder 14 adjacent with each broadside.Section 13 is rectangles, and knuckle-tooth shape is processed on the long limit of its both sides, pulverizes with convenient processing.By the pulverizing part that section 13, bearing pin 15, movable spacer 17, cabin spacer 16, slices holder 14 are formed, pulverize part and be installed on the main shaft 1.
Main shaft 1 is installed on left end bearing 3 and the right-hand member bearing 9, and left end bearing 3 and right-hand member bearing 9 are equivalent to two fulcrums of main shaft 1; The inside of left end bearing 3 and right-hand member bearing 9 all is equipped with bearing 4, by bearing 4 movingly, on left end bearing 3 and the right-hand member bearing 9 oil filler point 5 is installed all between main shaft 1 and left end bearing 3, the right-hand member bearing 9, and oil filler point 5 provides lubricating oil for bearing 4.Main shaft 1 is processed into the multidiameter shape, support by left end bearing 3 and right-hand member bearing 9, second key 11 on the main shaft 1 is used for fixing belt pulley 12, belt pulley 12 links to each other with power motor by belt, power motor drives belt pulley 12 rotations, belt pulley 12 drives main shaft 1 rotation, section 13 rotations under action of centrifugal force on the slices holder 14.
Main shaft 1 is a hollow shaft, and main shaft 1 is with to pulverize on the contacted position of part processing porose, the air free flow at these holes and main shaft 1 two ends.Two ports by main shaft 1 so just can obtain enough intakes to the pulverizing part air intake of pulverizer, can obtain better machining effect.No dead angle in the pulverizer by hole institute air intake power effect on the main shaft 1, makes the faster generation centrifugal force of crushed material during pulverizing, arrives to pulverize optimal site.During pulverizing, pulverize the part inner chamber under main shaft 1 center wind-force effect, can make and pulverize the back particle and fly out rapidly outside the sieve, make the operating efficiency of pulverizer improve 15 ~ 20%, obtained better technical effect.The air quantity of inside is little when efficiently solving the work of traditional pulverizer, and pulverizing near the spindle axis place has problems such as dead angle, pulverizer inefficiency.
Fig. 2 is the side view of hollow shaft pulverizer of the present invention; Can see belt pulley 12, section 13, slices holder 14, bearing pin 15 from figure.It is 13 in running order to cut into slices, and section 13 rotations are cut into slices 13 movable sets on bearing pin 15 under action of centrifugal force.
