The plowed soil is deposited at the entrance of the guide path 5, and the soil guiding frame 31 moves along with the pulling frame 1, so that the plowed soil enters the guide path 5, and then, once the soil moves to the position of the rotating ring 34 along the guide path 5, the rotating ring 34 presses the soil in the guide path 5 along with the rotation of the rotating shaft 36, so that the lump-shaped soil enters the inner sides of the pair of rotating rings 34 to complete crushing and screening actions (the rotating shaft 36 can be driven by an external driver such as a motor).
The rotation shaft 36 rotates together with the soil-crushing wheel cover 37, so that the soil in the form of a lump can be immediately clamped between the adjacent soil-crushing columns 38 after entering the inner sides of the pair of rotation rings 34, and when the soil-crushing wheel cover 37 rotates along with the rotation rings 34, the adjacent soil-crushing columns 38 crush the soil entering the inner sides of the pair of rotation rings 34 and clamp the soil difficult to crush, and then once the rotating soil-crushing wheel cover 37 drives the soil-crushing columns 38 to contact the shifting-stopping column cover 32, the shifting-stopping column cover 32 shifts the ends of the soil-crushing columns 38 to enlarge the gaps between the adjacent soil-crushing columns 38, so that the soil difficult to crush enters the soil-crushing wheel cover 37 to be pushed by the soil-covering wheel disc to perform the soil covering action, and the soil with large volume and difficult to crush cannot easily occur.
Compared with the prior art, the application can realize the adjustment of the soil crushing section and the independent storage of the adjusted and screened soil, so that the soil led out from the guide way 5 can not generate larger soil which is difficult to crush.
Further, in order to prevent the occurrence of the situation that weeds or plant roots in the ploughed soil cause the soil crushing wheel cover 37 to be clamped, it is preferable that the soil guiding frame 31 comprises a supporting bar 311 connected with the pulling frame 1, one end of the supporting bar 311 away from the pulling frame 1 is connected with a guiding cover 312, a guiding channel 5 is arranged in the guiding cover 312, one end of the guiding channel 5 is flush with the bottom of the ridging plow 2, and a lever embedding groove 313 corresponding to the position of the pair of rotating rings 34 is formed on the side wall of the other end of the guiding channel 5;

When the plowed-out soil enters the guide 5, a plurality of diagonal ratchet bars 314 (the diagonal ratchet bars 314 may be composed of diagonal bars and struts provided on the diagonal bars as shown in fig. 1 and 4 in detail) may play a role of loosening and trapping weeds or plant roots existing in the soil.
Further, in order to enable the adjacent soil crushing columns 38 to aim at the soil which has different volumes and is difficult to crush, the side wall of the rotating ring 34 is preferably sleeved with a return spring 341 between the adjacent screening rods 35, and the outer side of the return spring 341 is sleeved with a blocking sleeve 342 with the end part connected with the screening rods 35; the blocking sleeve 342 is used for blocking sundries from being blocked into the return spring 341.
In this embodiment, the rotating shaft 36 is connected to the rotating ring 34 through a straight rod.
When a larger volume of soil (not smaller than the gap between the adjacent crushed soil columns 38) is about to pass through the gap between the adjacent crushed soil columns 38, at this time, the soil pushes the adjacent crushed soil columns 38 to move towards the far side, and the movable crushed soil columns 38 drive the corresponding return springs 341 to move, so that the subsequent crushed soil columns 38 can be quickly reset, and the blocking sleeve 342 can block sundries from being blocked into the return springs 341, so that the normal use of the return springs 341 is not affected.
Further, in order to solve the problem that the soil difficult to crush falls down due to the holding, the soil crushing column 38 includes a holding portion 381 rotatably connected to the inside of the introduction port 6 by a rotation pin, one end of the holding portion 381 away from the introduction port 6 is connected with an inclined portion 382, and the other end of the holding portion 381 is connected with the adjusting member 39; the inclined portion 382 serves to block soil difficult to crush from falling.
When soil that is difficult to crush is to be entered between the adjacent rotating rings 34 (between the adjacent rotating rings 34 in the present application means a space composed of two rotating rings 34 and a screening rod 35 located between the two rotating rings 34).
The difficult-to-crush soil will push the sloped portions 382 open first, once fully between adjacent rotating rings 34, representing that the difficult-to-crush soil has been pinched between the sloped portions 382, at which time the sloped portions 382 will increase friction of the soil sidewalls to block the difficult-to-crush soil from falling.
Further, in order to solve the problem that the soil difficult to crush falls down from the inclined portion 382 without entering the introduction port 6, it is preferable that the locking post sleeve 32 comprises a fixed sleeve 321 sleeved on the side wall of the rotating shaft 36 and having an end portion connected to the support post frame 33, a pair of separation discs 322 are connected to the other side wall of the fixed sleeve 321, a movable chamber 323 is provided between the separation discs 322, a locking post 324 is provided in the movable chamber 323, the locking post 324 is rotatably connected to the inner wall of the movable chamber 323 in a reciprocating manner, and one end of the locking post 324 away from the separation discs 322 is connected to the fixing portion 381;
when the crushed soil column 38 is driven to move from the lowest point to the highest point of the soil crushing wheel cover 37, the stirring column 324 stirs the fixing part 381.
In this embodiment, the connection mode between the toggle post 324 and the movable chamber 323 can be preferably specifically that the side wall is connected with the rotation pin of the torsion spring, that is, one end of the rotation pin of the torsion spring is connected with the inner wall of the movable chamber 323, and the other end is not connected, so that the separation disc 322 can be moved away from each other.
In this embodiment, as shown in fig. 5, 6 and 7, the holding portions 381 are disposed specifically, and the holding portions 381 on the same side are all connected to the same rotation pin, so that when the single holding portion 381 is pushed to open, all the holding portions 381 can open.
When the soil crushing wheel cover 37 drives the soil crushing columns 38 and the soil between the adjacent soil crushing columns 38 to move, the holding part 381 is stirred by the stirring column 324 only when the soil crushing columns 38 move from the lowest point to the highest point of the soil crushing wheel cover 37, and then the holding part 381 is opened, so that the soil falls into the inlet 6, namely, enters the soil crushing wheel cover 37.
After the shifting post 324 is separated from the holding portion 381, the adjacent holding portion 381 (all the adjacent soil crushing posts 38 refer to the soil crushing posts 38 on the opposite sides in the same inlet 6) is reset under the pushing of the adjusting member 39, so that the subsequent soil is blocked by the holding portion 381 at the inlet 6 moving to the lowest point of the soil crushing wheel cover 37 and cannot easily run out, that is, an easily-in and difficultly-out blocking mechanism is formed by the holding portion 381, so that the soil can only be in the soil crushing wheel cover 37.
Further, in order to prevent the occurrence of the entry of soil into the soil-pulverizing wheel cover 37 due to insufficient crushing, it is preferable that the pair of partition plates 322 are each provided with a boss 325 on the corresponding rear surface, and the boss 325 is provided on the surface thereof with a plurality of soil-guiding bar groups 326 for guiding the movement of soil difficult to crush;
the inlet openings of the plurality of soil guiding bar sets 326 are arranged along a movement track for driving the crushed soil columns 38 to move from the lowest point to the highest point of the soil crushing wheel cover 37 (the arrangement is that the soil can enter the inlet openings of the soil guiding bar sets 326 no matter the soil is properly dropped in the process that the soil is driven to the highest point by the lowest point of the soil crushing wheel cover 37 by the fixing portion 381 in the introducing port 6).
After falling into the soil of the soil-pulverizing wheel housing 37 (or during the process that the holding portion 381 in the introduction port 6 is driven to the highest point by the lowest point of the soil-pulverizing wheel housing 37), the soil falls toward the boss 325 and directly enters the soil-guiding strip group 326, and the soil-guiding strip group 326 guides the movement of the soil difficult to crush so that the soil does not gather at the rotation shaft 36, and at the same time the soil moving at the soil-guiding strip group 326 contacts the soil many times so that the insufficiently crushed soil is crashed so that the reduced volume of the soil can fall from the introduction port 6.
Further, in order to prevent soil from accumulating in the soil crushing wheel cover 37 and being unable to be discharged, it is preferable that the surface of the soil crushing wheel cover 37 is provided with an opening 372, and an inclined guide groove 371 inclined downward toward the opening 372 side is provided on the inner side wall of the soil crushing wheel cover 37, and a blocking net 373 is detachably connected in the opening 372.
The inclined guide grooves 371 can guide the soil to move toward the blocking net 373 so as to be in a concentrated state without scattering in the soil crushing wheel cover 37, and the blocking net 373 can block the soil difficult to crush from falling directly and filter the soil at the same time so as to prevent the soil difficult to crush from accumulating more and causing the normal soil to be difficult to discharge.
Further, in order to prevent the difficult-to-crush soil from accumulating between the pair of separation discs 322 while increasing the movement of the soil to promote the soil to be discharged out of the soil-crushing wheel cover 37, it is preferable that the inner side walls of the pair of separation discs 322 are provided with gradation bars 327 at positions corresponding to the other ends of the dial posts 324, and the dial posts 324 can slide along the gradation bars 327 to push the pair of separation discs 322 away from each other when rotated;
a pull-back spring 328 is installed between the pair of separation discs 322;
the arc length of the gradual change bar 327 is not smaller than the rotation circumference of the toggle post 324 when rotating (this is done to prevent the toggle post 324 from being excessively clamped by the gradual change bar 327).
In this embodiment, the thickness of the graded bar 327 is also set to increase from one end to the other.
When the toggle post 324 is driven by the holding portion 381, the end portion of the toggle post 324 slides along the gradual change bar 327 to push the pair of separation discs 322 away from each other, so that the soil is pushed.
The rod selection caulking groove 313 is connected with a plurality of inclined guide bars 315, the inclined guide bars 315 are used for guiding the soil to move towards the center of the traction frame 1, so that the soil is prevented from being discharged from two sides of the rod selection caulking groove 313 when the screening rods 35 crush the soil, and meanwhile, the inclined guide bars 315 can also play a role in boosting the soil, so that the soil can enter between the adjacent rotating rings 34 without being blocked between the adjacent screening rods 35.
The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this application will occur to those skilled in the art, and are intended to be within the spirit and scope of the application.
