As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a preferred embodiment of the present invention provides a micro-tillage machine 100 with a tilling depth adjusting function, which includes a rotary blade holder 2, a walking wheel holder 3, a handrail bracket 4, a rotary blade assembly 5, a walking wheel 6 and a tilling depth adjusting member 7. The rotary blade fixing frame 2 is rotationally connected with the walking wheel fixing frame 3. One end of the handrail support 4 is fixed on the rotary blade fixing frame 2. The rotary blade assembly 5 is arranged on the rotary blade fixing frame 2 and used for loosening soil by scratching the ground. The road wheels 6 are rotatably arranged on the road wheel fixing frame 3. The tilling depth adjusting part 7 is arranged on the handrail support 4 and connected with the walking wheel fixing frame 3 and used for adjusting the rotating angle of the walking wheel fixing frame 3 so as to change the relative height of the rotary tillage cutter component 5 and the walking wheel 6, namely the rotary tillage depth.
In the present embodiment, the armrest support 4 specifically includes a support rod 42 and a grip rod 44. One end of the supporting rod 42 is fixed on the rotary blade fixing frame 2, one end of the holding rod 44 is rotatably connected with the supporting rod 42, and the other end of the holding rod 44 is connected with a handle 46. The holding rod 44 is forced to rotate relative to the support rod 42 so that the user can find a proper direction for applying force.
In the present embodiment, the rotary blade unit 5 specifically includes a motor 52 and a rotary blade 54. The motor 52 is installed on the side of the rotary blade holder 2 facing the handle support 4, the rotary blade 54 is located on the side of the rotary blade holder 2 facing away from the handle support 4, and the rotary blade 54 is connected to the motor 52 to be rotated by the motor 52. The mini-tiller 100 further comprises a forward rotation button 8 and a reverse rotation button 9, wherein the forward rotation button 8 and the reverse rotation button 9 are both arranged on the holding rod 44 and are respectively connected with the motor 52 to control the rotation of the motor 52, so that the mini-tiller 100 can be controlled to advance or reverse as required, and the mini-tiller is convenient to use. Preferably, the forward rotation button 8 and the reverse rotation button 9 are spaced apart from each other at an end of the holding rod 44 near the handle 46 for easy control by a user.
Referring to fig. 2 and 3, the tilling depth adjusting member 7 is located on a side of the road wheel fixing frame 3 opposite to the road wheels 6, and includes a fixing rod 72, a rotating rod 74, a connecting rod 76, a sliding sleeve 77 and a locking screw 78. One end of the fixing rod 72 is mounted on the supporting rod 42, and the other end of the fixing rod 72 has a rotation hole 722 formed therethrough. One end of the rotating rod 74 is rotatably installed on the supporting rod 42, and the other end of the rotating rod 74 is connected with the road wheel fixing frame 3. One end of the connecting rod 76 is protruded with a rotating shaft 762, and the other end of the connecting rod 76 is rotatably connected with the sliding sleeve 77. The rotating shaft 762 is rotatably inserted into the rotating hole 722, the sliding sleeve 77 is slidably sleeved on the rotating rod 74, and the connecting rod 76 can drive the sliding sleeve 77 to move along the rotating rod 74 when rotating, so as to drive the rotating rod 74 to rotate. The locking screw 78 is screwed with the fixing rod 72, and one end of the locking screw 78 can extend into the rotating hole 722 to abut against the rotating shaft 762 so as to prevent the rotating shaft 762 from rotating, specifically: the end of the fixing rod 72 away from the supporting rod 42 is further provided with a screw hole 724, and the screw hole 724 is communicated with the rotating hole 722. The locking screw 78 is engaged with the threaded hole 724, and rotation of the locking screw 78 moves the locking screw 78 along the threaded hole 724 until the rotating shaft 762 abuts against the sidewall of the rotating hole 722.
In the present embodiment, a flange 764 is further formed on the rotating shaft 762, and the flange 764 is located on a side of the connecting rod 76 opposite to the fixing rod 72 for rotating the connecting rod 76. Referring to fig. 1 again, a mudguard 10 is further disposed on a side of the rotary blade holder 2 away from the road wheel holder 3 to prevent soil from splashing around during tillage.
Referring to fig. 4 and 5, when the mini-tiller 100 is used, the locking screw 78 is rotated to move the locking screw 78 in a direction away from the rotating shaft 762, and the rotating shaft 762 is rotated through the flange 764, so as to drive the connecting rod 76 to rotate. The connecting rod 76 rotates to drive the sliding sleeve 77 to move along the rotating rod 74 so as to drive the rotating rod 74 to rotate, and further lift or lower the traveling wheel fixing frame 3 and the traveling wheel 6 fixed on the traveling wheel fixing frame 3, thereby changing the relative height, i.e. the rotary tillage depth, of the rotary tillage blade assembly 5 and the traveling wheel 6. After the rotary tillage depth adjustment is completed, the locking screw 78 is rotated to enable the locking screw 78 to move towards the rotating shaft 762 until the rotating shaft 762 is tightly abutted against the side wall of the rotating hole 722 to prevent the rotating shaft 762 from rotating, so that the walking wheel fixing frame 3 is stably fixed at a required angle.
The mini-tiller 100 according to the embodiment of the present invention can drive the sliding sleeve 77 to move along the rotating rod 74 by rotating the connecting rod 76 of the tilling depth adjusting member 7, so as to drive the rotating rod 74 to rotate, and further raise or lower the traveling wheel fixing frame 3 and the traveling wheel 6 fixed on the traveling wheel fixing frame 3, thereby changing the relative height between the rotary tillage cutter assembly 5 and the traveling wheel 6, i.e., the rotary tillage depth. In addition, the tilling depth adjusting part 7 is located on the side of the walking wheel fixing frame 3 opposite to the rotary blade 54, so that the weeds can be prevented from being wound on the tilling depth adjusting part 7, and the adjustment by an operator is facilitated.
It will be appreciated that in other embodiments, one end of the rotating lever 74 may be rotatably mounted on the fixed lever 72.
It is understood that in other embodiments, the forward rotation button 8 and the reverse rotation button 9 may be mounted on the support rod 42.
It will be appreciated that the flange 764 may be omitted, in which case the connecting rod 76 may be toggled directly to rotate it.
The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
