Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the rotary tillage shaft 1, the cutter group 2, the primary cutter 201, the secondary cutter 202, the reinforcing ribs 3, the positioning pins 4, the second through holes 5, the positioning holes 6, the bolts 7, the nuts 8, the cross cutters 9 and the connecting rods 10.
Example one
This embodiment is substantially as shown in fig. 1 and 2: a mini-tiller with adjustable tilling depth comprises a rotary tillage shaft 1, wherein a plurality of cutter groups 2 are arranged on the rotary tillage shaft 1 along the length direction, and in the embodiment, 20 cutter groups 2 are provided. Each cutter group 2 comprises a primary cutter 201 and a secondary cutter 202, and the primary cutter 201 and the rotary tillage shaft 1 are integrally formed.
The thicknesses of the primary cutter 201 and the secondary cutter 202 decrease continuously from the middle to both sides (both sides refer to the front and rear sides of the cutter in fig. 1). The middle parts of the primary cutter 201 and the secondary cutter 202 are welded with vertically arranged reinforcing ribs 3, so that the strength of the primary cutter 201 and the strength of the secondary cutter 202 are enhanced.
The first through-hole of horizontal setting is seted up at the middle part of one-level cutter 201, and one-level cutter 201 integrated into one piece has locating pin 4. The middle of the secondary cutter 202 is provided with a plurality of second through holes 5 and positioning holes 6 arranged transversely along the length direction, in this embodiment, the number of the second through holes 5 and the positioning holes 6 is three. The first through hole and the second through hole 5 are threaded holes, a bolt 7 with a nut 8 is in threaded connection with the first through hole 5, and the positioning pin 4 is located in one positioning hole 6. The second-level cutter 202 is far away from and one end of the cutter is integrally formed with a transverse cutter 9, and the transverse cutter 9 is horizontally arranged.
The specific implementation process is as follows: before starting the micro-tillage machine and when the tillage depth needs to be adjusted, a wrench or other tools are used for taking the nut 8 on the bolt 7 off the bolt 7, then the bolt 7 is rotated, the bolt 7 is taken out of the first through hole and the second through hole 5, the secondary cutter 202 is taken off from the primary cutter 201, and at the moment, the positioning pin 4 is separated from the positioning hole 6 on the secondary cutter 202. Then, the user selects the coupling position of the secondary cutter 202 and the primary cutter 201 as desired, thereby obtaining a desired tilling depth. For example, when a large tillage depth is required, the second through hole 5 of the secondary cutter 202, which is farthest from the cross blade 9, is aligned with the first through hole of the primary cutter 201, and then the secondary cutter 202 is mounted on the primary cutter 201, in the process, the positioning pin 4 on the primary cutter 201 extends into the positioning hole 6 of the secondary cutter 202, which is farthest from the cross blade 9, the user passes the bolt 7 through the second through hole 5 and the first through hole, the nut 8 is remounted on the bolt 7 by using a wrench or other tools, the nut 8 is screwed, and the secondary cutter 202 is fixedly connected to the primary cutter 201, and at this time, the micro-tillage machine has a large tillage depth. When the mini-tiller works, the positioning pin 4 on the first-stage cutter 201 and the positioning hole 6 on the second-stage cutter 202 can prevent the first-stage cutter 201 and the second-stage cutter 202 from rotating circumferentially relatively, so that the cutter group 2 works normally.
In summary, in this embodiment, the user can adjust the connecting position of the secondary cutter 202 and the primary cutter 201 as required, so as to adjust the overall length of the cutter group 2, and further realize the adjustment of the tilling depth of the mini-tiller.
Example two
The difference between the first embodiment and the second embodiment is that, as shown in fig. 3, the two secondary cutters 202 in two adjacent cutter groups 2 located on the same horizontal line are fixedly connected by the connecting rod 10, and the connecting rod 10 is located at the top end of the secondary cutters 202, that is, the connecting rod 10 is located at the end of the secondary cutters 202 far away from the cross knife 9.
In this embodiment, the secondary cutters 202 located on the same horizontal line are connected to each other through the connecting rod 10, and the stress between the secondary cutters 202 can be mutually transmitted, thereby improving the integrity of the secondary cutters 202. When the positioning pin 4 on one of the primary cutters 201 is damaged, the secondary cutter 202 corresponding to the primary cutter 201 still cannot rotate relative to the primary cutter 201, and can continue to work. Moreover, when the user adjusts the tilling depth, the positions of all the secondary cutters 202 on the same horizontal line can be adjusted at one time, and then the secondary cutters 202 are fixed, so that the operation is quicker.
The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be pointed out that to those skilled in the art, without departing from the structure of the present invention, a plurality of modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the utility of the present invention.
