Specific embodiment
Below by the description to embodiment, the shape of for example related each component of a specific embodiment of the invention, structure It makes, the mutual alignment between each section and connection relationship, the effect of each section and working principle, manufacturing process and the side of operating with Method etc., is described in further detail, completeer to help those skilled in the art to have inventive concept of the invention, technical solution Whole, accurate and deep understanding.
As shown in Figure 1 to Figure 3, present embodiment provide it is a kind of with can vibrating subsoiling shovel subsoiler technical side Case, including rack 1 are equipped with multiple deep soil loosing shovels 2 below rack 1, and spill spin block 3 is fixedly connected at the top of deep soil loosing shovel 2, and spill spin block 3 is living Dynamic to be installed on inside rotary sleeve 4, rotary sleeve 4 is fixedly mounted on 1 bottom of rack, passes through rotary shaft between rotary sleeve 4 and spill spin block 3 5 are connected, and vibrating arm 6 is also connected on the deep soil loosing shovel 2, and the other end of vibrating arm 6 is connected with vibrating disk 7, vibration circle Disk 7 is rotatably mounted on disc shaft 8, and disc shaft 8 is fixedly connected with multiple fixed links 9, multiple fixed peaces of the fixed link 9 Mounted in 1 bottom of rack, it is additionally provided with fixed stop 10 in the disk of the vibrating disk 7, vibration is connected on fixed stop 10 Spring 11, the other end of vibrating spring 11 are fixedly connected on support portion 12, and the support portion 12 is set to 10 lower section of fixed stop, Support portion 12 is fixedly connected with connecting rod 13, and connecting rod 13 is fixedly mounted on 1 bottom of rack.
The Oscillation Amplitude of deep soil loosing shovel 2 is unable to control in a certain range.The vibrating disk 7 is also fixedly connected with connecting rod 14, connecting rod 14 is connected with adjusting rod 15, and 15 top of adjusting rod is connect with rack 1, and 15 bottom end of adjusting rod offers vibration hole 16, connecting rod 14 is movably installed in inside vibration hole 16, and the diameter in vibration hole 16 is greater than the diameter of connecting rod 14, so that the work of connecting rod 14 Dynamic amplitude is limited at the inside in vibration hole 16, and then is controlled the Oscillation Amplitude of vibrating disk 7, so that it is deep to reach control The purpose of the Oscillation Amplitude of pine shovel 2.
The Oscillation Amplitude of deep soil loosing shovel 2 described in multiple groups is identical, so that its vibration frequency is reached unanimity, is also possible in some cases Cause the resonance with entire machine, thus machine is caused to damage, and the effect of its subsoiling is also general, multiple vibration holes 16 Diameter is different, to achieve the purpose that make the Oscillation Amplitude of deep soil loosing shovel 2 described in multiple groups different, extend machine uses the longevity Life, improves the effect of subsoiling.
In Subsoiler, it is often necessary to adjust Oscillation Amplitude, the upper half of the adjusting rod 15 according to different soils Portion, which is arranged with, adjusts loop bar 18, and 15 upper half of adjusting rod offers annular groove 17, adjusts and is equipped with annular strip inside loop bar 18 19, annular strip 19 is matched with annular groove 17, separate adjusting loop bar 18 can not up and down with adjusting rod 15, but can phase To rotation, rack 1 offers threaded hole 20, adjusts rod set 18 by being threadedly engaged movable up and down be installed in threaded hole 20 Portion, adjusting rod set 18 can also be used to be dismantled with being threadedly engaged for threaded hole 20.
In operation, it is sometimes desirable to determine different subsoiling depth according to different soil situations and different bury Angle, the top for adjusting rod set 18 are additionally provided with helical teeth dome 21, and helical teeth dome 21 is connected with adjusting by gear teeth meshing and turns Bar 22, by rotation adjust bull stick 22 drive adjust rod set 18 rotation, control to adjust rod set 18 in threaded hole 20 up and down It is mobile, make adjusting rod 15 that connecting rod 14 be driven to rotate, and then rotate vibrating disk 7, so that the subsoiling for reaching adjusting deep soil loosing shovel 2 is deep The purpose of degree and angle of penetration.
It is faster accurate in order to make to adjust because present embodiment is equipped with multiple deep soil loosing shovels, the adjusting bull stick 22 Laterally setting, and adjust bull stick 22 and be connected with multiple helical teeth domes 21 simultaneously by gear teeth meshing adjusts bull stick 22 and tiltedly Tooth dome 21 is set to inside protection cap 23, is adjusted 22 both ends of bull stick and is rotatably affixed on the tegmental wall of protection cap 23, and adjusts Section 22 one end of bull stick reaches outside protection cap 23, and the part for adjusting the stretching protection cap 23 of bull stick 22 is equipped with dial, for convenience It holds, the part for adjusting the stretching protection cap 23 of bull stick 22 is also equipped with regulation handle.
In order to avoid connecting rod 14 is detached from inside vibration hole 16, end of the connecting rod 14 far from vibrating disk 7 is also fixedly mounted There is anti-delinking part 26, anti-delinking part 26 can not pass through from vibration hole 16.
The working principle of the invention is: carrying out in use, deep soil loosing shovel 2 can be adjusted according to different soil situations first Angle of penetration and subsoiling depth, dial 24 and is observed at regulation handle 25 by rotation, makes to adjust bull stick 22 and rotates, adjusts and turns Bar 22 drives each adjusting loop bar 18 to rotate, and adjusts loop bar 18 and threaded hole 20 cooperates, so that adjusting loop bar 18 drives adjusting rod 15 It rises or falls, adjusting rod 15 drives connecting rod 14 to move, so that vibrating disk 7 rotates, vibrating disk 7 is pulled by vibrating arm 6 Deep soil loosing shovel 2 does the rotation of certain angle, achievees the purpose that adjust deep soil loosing shovel 2, while can also be pacified according to different soil situations Harness has the adjusting rod of the adjustment hole of suitable pore size, to achieve the purpose that control deep soil loosing shovel amplitude, is carrying out work subsoiling When operation, 2 stress extrusion and vibration bar 6 of deep soil loosing shovel, vibrating arm 6 pushes vibrating disk 7, and vibrating disk 7 passes through the fixed peace of its disk The 10 extrusion and vibration spring 11 of fixed stop of dress, achievees the purpose that vibration.Realize at the same to 2 angle of penetration of multiple groups deep soil loosing shovel and The adjusting of subsoiling depth, efficient and convenient, the setting of dial 24 keeps adjusting more accurate, by the setting of vibrating disk 7, makes Deep soil loosing shovel 2 is able to carry out vibration when carrying out subsoiling, improves subsoiling quality, while reducing the loss of energy, respectively vibrates hole 16 pore size is different, keeps the Oscillation Amplitude of each deep soil loosing shovel 2 and vibration frequency different, further improves the matter of subsoiling Amount, extends machine service life.
The present invention is exemplarily described above, it is clear that present invention specific implementation is not subject to the restrictions described above, As long as using the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out, or not improved this is sent out Bright conception and technical scheme directly apply to other occasions, within the scope of the present invention.Protection of the invention Range should be determined by the scope of protection defined in the claims.
