DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 Figure 2 As shown, a soil loosening device for garden soil improvement comprises a frame (1), a push rod (3) is provided on the frame (1), a spraying assembly (2) is installed on the frame (1), and the characteristics are: an alarm (4) is fixedly installed on the upper surface of the frame (1), a rotating rod (5) is movably installed in the frame (1), a blade assembly (6) is fixedly installed on the rotating rod (5), the blade assembly (6) comprises a fixed sleeve (607) fixed on the rotating rod (5), a connecting outer ring (604) is fixedly installed on the fixed sleeve (607), a connecting inner ring (606) is movably installed in the connecting outer ring (604), and the connecting A movable sleeve (602) is fixedly mounted on the inner ring (606), and a blade body (601) is fixedly mounted on the movable sleeve (602). A torsion spring (605) is provided between the connecting outer ring (604) and the connecting inner ring (606), and a warning mechanism (7) is provided between the connecting outer ring (604) and the connecting inner ring (606). The blade body 601 on the blade assembly 6 will twist when encountering a stone, so that the rotating rod 5 cannot continuously apply a large torque to the stone to block the blade body 601, thereby preventing the blade body 601 from being deformed by force, and the warning mechanism 7 can remind the user that there are stones underground when encountering stones and they need to be manually handled.

[0023] like Figure 3As shown, the blade assembly (6) includes a fixed sleeve (607) fixed on the rotating rod (5), a connecting outer ring (604) is fixedly installed on the fixed sleeve (607), a connecting inner ring (606) is movably installed in the connecting outer ring (604), a movable sleeve (602) is fixedly installed on the connecting inner ring (606), a blade body (601) is fixedly installed on the movable sleeve (602), a torsion spring (605) is provided between the connecting outer ring (604) and the connecting inner ring (606), and the blade assembly (6) also includes a fixing bolt (603) arranged on the fixed sleeve (607), and the fixed sleeve (607) is fixed to the rotating rod (5) by the fixing bolt (603).

[0024] Specifically, the rotating rod 5 can drive the blade body 601 to rotate, thereby turning over the soil on the ground. When the blade body 601 encounters a stone and cannot turn over the stone, the connecting inner ring 606 will rotate in the connecting outer ring 604, so that the rotating rod 5 cannot continue to apply a large torque to the stone blocking the blade body 601, thereby preventing the blade body 601 from being deformed by the force. At the same time, when the blade body 601 is moved away from the stone, the torsion spring 605 will drive the blade body 601 to reset, so that the blade body 601 remains on the rotating rod 5, which is convenient for turning over the soil at other positions.

[0025] like Figure 4 As shown, an alarm (4) is fixedly mounted on the upper surface of the frame (1), and the warning mechanism (7) includes a driving gear ring (701) fixed on the connecting inner ring (606) and a knob switch (704) fixed on the connecting outer ring (604), a control input shaft (703) is provided on the knob switch (704), and a driven gear (702) is fixedly mounted on the end of the control input shaft (703), and the warning mechanism (7) also includes a docking base (705) fixed on the knob switch (704), and docking through holes (706) are provided at the four corners of the docking base (705).

[0026] Specifically, the inner connecting ring 606 rotates inside the outer connecting ring 604, causing the driving gear ring 701 to rotate. After the driving gear ring 701 rotates, it causes the driven gear 702 to rotate. After the driven gear 702 rotates, it causes the control input shaft 703 on the knob switch 704 to rotate. When the blade body 601 is twisted at a large angle, the control alarm 4 is activated, and when the blade body 601 encounters a stone, the user is reminded that there are stones underground that need to be handled manually.

[0027] It should be noted that the utility model is a soil loosening device for garden soil improvement. In actual use, the frame 1 is first pushed forward. When the frame 1 is pushed forward, the motor can be used to drive the rotating rod 5 to rotate. After the rotating rod 5 rotates, it will drive the blade body 601 to rotate and turn over the soil on the ground. During the turning process, once the blade body 601 encounters a stone and cannot turn over the stone, the connecting inner ring 606 will rotate in the connecting outer ring 604 to twist the blade body 601, so that the rotating rod 5 cannot continue to apply a large torque to the stone blocking the blade body 601, thereby preventing the blade body 601 from being deformed by force. At the same time, since one end of the torsion spring (605) is fixed on the connecting outer ring (604), the torsion spring (605) is The other end of the torsion spring (605) is fixed on the connecting inner ring (606), so when the moving blade body 601 leaves the stone, the torsion spring 605 will drive the blade body 601 to reset, so that the blade body 601 remains on the rotating rod 5, which is convenient for turning over the soil in other positions. At the same time, the connecting inner ring 606 rotates in the connecting outer ring 604 so that it will drive the driving gear ring 701 to rotate. After the driving gear ring 701 rotates, it will drive the driven gear 702 to rotate. After the driven gear 702 rotates, it will drive the control input shaft 703 on the knob switch 704 to rotate, so that the knob switch 704 is used to control the alarm 4 to start, and then when the blade body 601 encounters a stone, it reminds the user that there are stones underground that need to be handled manually.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
