Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation: as shown in Figure 1: a kind of stalk crasher, this cracker comprises top disintegrating mechanism, feeding unit and end disintegrating mechanism, described top disintegrating mechanism comprises the first crushing bin 1, the rotary cutter shaft with the first blade 2 is provided with in the first crushing bin 1 inside, the tool rest 3 matched with rotary cutter shaft is provided with at the inwall of the first crushing bin 1, described first crushing bin 1 is with charging aperture 4 and discharging opening 5, and described discharging opening 5 place is provided with the retainer base 6 of liftable and rotation; Described feeding unit comprises the conveyer belt 7 that top is positioned at discharging opening 5 place, and the transmission direction of conveyer belt 7 is provided with material shovel, and described material shovel moves up and down by means of hoisting frame; Described end disintegrating mechanism comprises the second crushing bin 8, the bottom of described second crushing bin 8 is the bottom 9 of liftable and rotation, bottom 9 is vertically provided with the first particle fork 10, be provided with the platen 11 that can move up and down in the second crushing bin 8 inside at the Hatch Opening place of the second crushing bin 8, the lower surface of described platen 11 is provided with to be pitched 10 the second particles matched with the first particle and pitches 12.
About top disintegrating mechanism: as Fig. 1, Fig. 2, shown in Fig. 3, first crushing bin 1 is in horizontally disposed cylindrical-shaped structure, described charging aperture 4 is positioned at the top of the first crushing bin 1, described charging aperture 4 is in strip, the length of described charging aperture 4 is equal with the length of the first crushing bin 1, described discharging opening 5 is positioned at the bottom of the first crushing bin 1, the length of described discharging opening 5 is also equal with the length of the first crushing bin 1, supporting seat 13 is connected with at the two ends of the first crushing bin 1, described retainer base 6 is the arcuate shape matched with the shape of discharging opening 5, the two ends of described retainer base 6 are connected with the piston rod rotation of inner first cylinder 15 of supported on both sides seat 13 by the first rotating shaft 14.The cross section of described rotary cutter shaft is fan-shaped, described rotary cutter shaft comprises central shaft 16 and is evenly distributed on four cutter hubs 17 of central shaft 16 circumferencial direction, the length of described central shaft 16 and cutter hub 17 is all equal with the cavity length of the first crushing bin 1, at the first blade 2 that the end of cutter hub 17 is strip, the inwall of the first crushing bin 1 is distributed with along the circumferencial direction of the first crushing bin 1 tool rest 3 of strip, the cross section of described tool rest 3 is triangular in shape, described tool rest 3 is with the second blade, and described rotary cutter shaft is by means of the first electric machine rotation.
Under the drive of the first motor, rotary cutter shaft constantly rotates, the first blade 2 on cutter hub 17 cooperatively interacts with the second blade on tool rest 3, constantly move under the drive of rotary cutter shaft in time crop being put in the first crushing bin 1 by charging aperture 4, when crop is through the first blade 2 and the second blade intersect local time, cut off by two blades, through constantly cutting, crop is cut into sectional compact shape, when the preliminary cutting of crop puts in place time, the piston rod of the first cylinder 15 is declined, such retainer base 6 just declines thereupon, retainer base 6 automatic turning under gravity when retainer base 6 leaves discharging opening 5 time, crop above retainer base 6 is poured onto on conveyer belt 7, then the retainer base 6 of upset is made to reset manually, and rise to discharging opening 5 position, this is the preliminary shredding stage of crop.
About feeding unit: as Figure 1 and Figure 4, material shovel is made up of shovel material portion 27 and the portion 28 that gathers materials, described shovel material portion 27 with the shovel charge level 29 of ramped shaped, described in the gather materials top in portion 28 be the material collecting tank 30 of circular arc.Described hoisting frame comprises two vertical beams be oppositely arranged 18, upgrade block 19 is connected with on the top of two vertical beams 18, two vertical beams 18 are provided with vertical rail 20, the both sides of described material shovel are rotationally connected with vertical rail 20 by the second rotating shaft 21, the second motor is provided with in the upgrade block 19 at top, the clutch end of described second motor is connected by the two ends of rope with downside second rotating shaft 21, is connected with the crank 22 for rotating material shovel in one end of the second rotating shaft 21.
Can move along with the motion of conveyer belt 7 when crop is put on conveyer belt 7 time, can be scooped up by the shovel charge level 29 of material shovel in time moving to material shovel, and ahead running is in material collecting tank 30, when the crop in material collecting tank 30 is collected after suitable height, open the second motor, the vertical rail 20 that second motor pulls rope that material is shoveled along both sides rises, when rising to suitable height, manually move crank 22 second rotating shaft 21 is rotated thus makes material shovel upset, be poured onto by crop in the second crushing bin 8, this process is the process that the haul of crop promotes and shifts.
About end disintegrating mechanism: as shown in Fig. 1, Fig. 5 and Fig. 6, second crushing bin 8 is in the cylindrical structural vertically arranged, the open top of described second crushing bin 8, bottom 9 is provided with a row be vertically fixed on bottom 9 upper surface first particle fork 10, the diameter of described platen 11 is equal with the internal diameter of the second crushing bin 8, be provided with at the lower surface of platen 11 the second particle fork 12 that a row is vertically fixed on platen 11 lower surface, described first particle fork 10 and the second particle are pitched 12 in the vertical directions and not to be overlapped and mutually arranged in a crossed manner in the horizontal direction.The end face of described platen 11 is connected with the piston rod of the second cylinder 23, the lower surface of described bottom 9 is connected with the clutch end of the 3rd motor 24, bearing 25 is provided with in the bottom of the 3rd motor 24, described bearing 25 is connected with the piston rod of the 3rd cylinder 26, the piston rod ejection direction of described second cylinder 23 is downward, and the piston rod ejection direction of described 3rd cylinder 26 upwards.
When crop delivers to the inside of the second crushing bin 8, platen 11 is driven to do descending motion by the second cylinder 23, the crop of dropping on like this on bottom 9 is compressed between platen 11 and bottom 9, as shown in Figure 5, 10 mutual arranged crosswise pitched by the second particle fork 12 after platen 11 declines on platen 11 and the first particle on bottom 9, now crop is positioned between the two, start the 3rd motor 24, bottom 9 is constantly rotated, first particle fork 10 is also continuous simultaneously rotates between the space of the second particle fork 12, such crop is just pulverized by two particle forks by force, effect in addition in order to strengthen pulverizing can also arrange blade on the first particle fork 10 and the second particle fork 12, more easily cut rotating like this, after pulverizing, declined by the piston rod of the 3rd cylinder 26, bottom 9 is declined, thus the crop of pulverizing is taken out.
In sum: this cracker is pulverized by the preliminary pulverizing at top and the degree of depth of end, high efficiency crop can be pulverized, two particle forks particularly in the second crushing bin, rotated by the intersection of two particle forks, crop can be carried out very complete pulverizing, and transmit crop by feeding unit between the first crushing bin and the second crushing bin, the pulverizing of quickening and the speed of transmission.
