Abstract
The invention belongs to the herding facility that herbage and crops cane are processed into grass meal.The present invention is mainly finished by shear the pulverizing of herbage, and the adapted power of motor reduces 30%~70% under the same product throughput rate condition.
Description
The invention belongs to the herding facility that herbage and crops cane are processed into grass meal.Grass meal is widely used in the feed industry as one of raw material of pellet and manufactured feed.Difference according to feeding requirement, the grass meal granularity generally will reach the degree by diameter 2-6 millimeter sieve aperture, widely used both at home and abroad at present is the common hammer mill of the tangential feeding for the treatment of grain, 9F50 set hammer formula cracker as No. 90457, Russian Patent and China, the bigger machine of processing granularity, the swing roller attrition mill is arranged, as No. 4106706, United States Patent (USP), the domestic blue or green dry feed cracker that has is equipped with several reamer radially at axial feeding mouth place, fragile material can be hinged into section or piece more than 10 millimeters, and then be fed in the pulverizing chamber and pulverize, because this device can not cut with scissors disconnected herbage, so can not be used for processing grass meal.The machine of existing various pulverizing herbages be with herbage directly to the pulverizing chamber feeding, the hammer leaf that relies on high-speed motion applies to hit to livestock and pulverizes.The common drawback of these machines is that energy consumption is very big.Task of the present invention is to reduce the energy consumption that herbage is pulverized.
Major technique feature of the present invention is: pulverize the method for herbage, the shearing that main dependence is paid by stationary knife and at least one cutting that moving knife is formed is finished, rather than relies on hammer leaf to hit.Because the herbage fiber is a toughness material, its longitudinal strength is far longer than transverse strength, mainly consumes in vertical fragmentation of fiber so pulverize the herbage energy consumption, and is well-known, and the energy consumption that strikes off fiber is much larger than the energy consumption of shearing cut staple.So the present invention adopts cutting method to make the fiber slit shearing, and only through once shearing, the most of or overwhelming majority of the careless section fibre length of cutting-out is less than the degree of sieve diameter, because of the fiber transverse strength low.Fiber is laterally also most of broken in shear history, yet, owing to reason such as herbage is irregular, a small amount of size is arranged unavoidably greater than the sieve diameter person in the grass section that cuts out, so again the grass section is sent in the hammer mill, utilize the sieve sheet of cracker will be wherein the size eligible sieve away, a small amount of oversize person hits pulverizing by hammer leaf.The present invention is made up of shredding mechanism and cracker two parts on device.Shredding mechanism can be that the garden disc type also can be the common cracker that the drum-type cracker can adopt ground cereal.
The present invention compared with the prior art, under productivity ratio the same terms, the adapted power of motor descends 30%~70%, cost is close or decrease.
By accompanying drawing two embodiment of the present invention are illustrated below.Accompanying drawing 1 is the schematic diagram of the grass grinder of 1 ton/hour of productivity ratio, (I) is cylinder cutting mechanism, (II) is cracker, by conveyer belt (1), under feed roller (2), the intake mechanism of going up feeding roller (14) composition that floats is forced to deliver to stationary knife (3) equably with herbage (15) and is located, moving knife (4) and motor (5) coaxial line and rotation synchronously, 200 millimeters of moving knife tactical diameters, the cutting of being made up of stationary knife (3) and moving knife (4) is paid herbage is cut into 1~5 millimeter grass section (6), transport in the cracker (II) by pipeline (13) then, under the centrifugation of the strike of hammer leaf (7) and sieve sheet (8), grass meal (11) by sieve sheet (8) is blown out outside the machine by fan (9), motor (10) and fan (9), rotor mill (12) coaxial line rotates.15 kilowatts of motor (10) power, 2920 rev/mins of rotating speeds, 7.5 kilowatts of motor (5) power, 2920 rev/mins of rotating speeds.The every cutting of moving knife once, herbage is the theory chopping length of grass section to the feeding length of stationary knife direction, the grass theoretical chopping of section length should equal 1/2~5/6 of sieve aperture straight hole.One of adjusting way of grass segment length is: the quantity of increase and decrease moving knife (4).For example remove symmetry two moving knife (4), the grass theoretical chopping of section length will increase by 1 times, two of adjusting way is: the feeding linear velocity that changes the intake mechanism of being made up of conveyer belt (1), lower roll (2), top roll (14), the adjusting of feeding linear velocity can utilize the change of gearratio to realize that method for designing can be with reference to the intake mechanism of common hay cutter.
Accompanying drawing 2 is another embodiment, and shredding mechanism (III) has omitted intake mechanism, and herbage is directly fed by the people, and this mode is simple in structure, is suitable for the occasion that productivity ratio is lower than 300 kilograms/hour.Herbage (19) places hopper (32), and to feeding of stationary knife (18) direction and driven knife (25) chopping, the grass section is directly sucked and sieves and pulverize by cracker (24) by manually.Limit for length's plate (21) can limit the chopping length of grass section, moving knife rotor (17) is gone up or limit for length's plate (21) is provided with slotted hole (26), they link with bolt (23), limit for length's plate (21) can be pressed radially regulating of swivel (17), to realize the adjusting of grass chopping length, for making things convenient for the adjusting of moving knife (25) and limit for length's plate (21), upper casing (22) can be around bearing pin (27) revolution more than 180 ° behind the screw that comes loose (20).Hopper (32), upper casing (22), stationary knife (18) all are loaded on the housing (31), housing (31) links with bolt and cracker (24), nut (30) comes loose, housing (31) together can be taken off together with dress each parts thereon, to be convenient for changing the consumable accessory of cracker, moving knife rotor (17) and rotor mill (29) and motor coaxle line and rotation synchronously.
Claims (6)
1, a kind of processing method that is used to pulverize herbage and crops cane is characterized in that the fragmentation of herbage fiber in the shearing grass grinder, the shearing that elder generation pays through the cutting of stationary knife and moving knife composition, and the grass section that will cut out is again sent into screening and pulverizing in the hammer mill.
2, a kind of shearing grass grinder that is used to pulverize herbage and crops cane, it is characterized in that forming by shredding mechanism (I), (III) and cracker, herbage and crops cane cut the once shearing of paying in shredding mechanism (I), (III), chopping length is adjustable in 1~5 millimeter scope.
