Description

Technical Field

[0001] The present invention relates to the technical field of green plant planting, and in particular to a soil turning device for green plant planting. Background Art

[0002] With the acceleration of urbanization, urban greening has attracted more and more attention. Green plants not only beautify the environment, but also purify the air and improve the ecological environment. However, the healthy growth of green plants is inseparable from good soil conditions. When planting green plants, tools are needed to dig holes and turn the soil. The existing turning device is relatively simple. It uses a motor to drive the rotating shaft with blades fixed to rotate, so as to dig holes and turn the soil. When turning the hard soil, it cannot be adjusted, resulting in poor turning effect. Summary of the invention

[0003] In view of the above-mentioned prior art, the present invention provides a soil turning device for planting green plants, which can be adjusted according to the hardness of the soil to improve the effect of soil turning.

[0004] To achieve the above object, the technical solution of the embodiment of the present invention is implemented as follows:

[0005] A soil turning device for planting green plants comprises a movable frame, a connecting arm, a rotating shaft, a sleeve, a torsion spring sheet, a rotating plate and a motor. The connecting arm is provided at the front end of the movable frame. The connecting arm is rotatably connected to a plurality of rotating shafts. The rotating shafts are connected to the motor through a transmission mechanism. The lowest sleeve is connected to the rotating shaft, and the remaining sleeves are rotatably connected to the rotating shaft. Adjacent sleeves are connected through a torsion spring sheet. The rotating plate is fixed on the sleeve, and the rotating plates are staggered to form spiral blades.

[0006] Furthermore, the bottom and top of the rotating piece are planes, the side of the rotating piece is arc-shaped, and the tops and bottoms of adjacent rotating pieces fit together.

[0007] Furthermore, a limiting slide block is provided at the upper end of the sleeve, and a limiting slide groove is provided at the lower end of the sleeve, and the limiting slide block of the sleeve slides along the limiting slide groove of another adjacent sleeve.

[0008] Furthermore, the transmission mechanism includes a driving gear and a driven gear, the driving gear is connected to the motor, the motor is fixed on the connecting arm, the driving gear is meshed with the driven gear, and the driven gear is connected to the rotating shaft.

[0009] Furthermore, the mobile frame includes a frame body, rollers and armrests, the rollers are rotatably connected to the frame body, the armrests are connected to the rear end of the frame body, and the connecting arms are connected to the front end of the frame body.

[0010] Furthermore, the rotating shaft is a hollow shaft with an inner cavity, the side wall of the rotating shaft is provided with a plurality of first through holes, the inner wall of the sleeve is provided with a plurality of limit holes, the inner cavity of the rotating shaft is provided with a push rod, the upper end of the push rod is threadedly connected to the rotating shaft, the push rod is arranged in an annular groove, the depth of the upper end of the annular groove is smaller than the depth of the lower end, a limit rod is slidably connected in the first through hole, and the limit rod is connected to the elastic element.

[0011] Furthermore, the elastic element includes a spring, a plunger and a first bellows, the plunger is slidably connected to the limiting hole, the first bellows connects the plunger and the inner wall of the limiting hole, the spring is arranged in the first bellows, and the spring pushes the plunger to move outward.

[0012] Furthermore, the end of the plunger facing the limiting rod is hemispherical.

[0013] The beneficial effects of the present invention are as follows: in the initial state, the pitch of the spiral blades formed by the plurality of rotating pieces is large. As the rotating shaft rotates, the rotating pieces are deflected by resistance in the soil. The greater the resistance, the greater the deflection angle, which eventually reduces the pitch of the spiral blades formed by the plurality of rotating pieces, making it easier to penetrate into hard soil. When the rotating pieces are screwed into the soil, the rotating pieces located at the top are subject to less resistance, so the pitch of the spiral blades formed by the rotating pieces located at the top is large, which can discharge the soil above upward, which is conducive to the rotating pieces at the bottom being screwed into the soil, and is convenient for turning over the hard soil. The connecting arm of the present invention is provided with a plurality of rotating shafts, and the plurality of rotating shafts work synchronously to turn over the soil. The spiral blades formed by the rotating pieces subject to less resistance from the soil have a large pitch, which can turn over this part of the soil, thereby reducing the squeezing of the soil on other areas with greater resistance, and making it easier for other areas with greater resistance to be screwed in.

[0024] Example 1

[0025] Please refer to the attached Figures 1 to 4The present application provides a soil turning device for planting green plants, comprising a mobile frame 1, a connecting arm 2, a rotating shaft 3, a sleeve 4, a torsion spring 5, a rotating plate 6 and a motor 7. The front end of the mobile frame 1 is provided with the connecting arm 2, and the connecting arm 2 is rotatably connected to a plurality of rotating shafts 3. The rotating shaft 3 is connected to the motor 7 through a transmission mechanism. The bottom sleeve 4 is connected to the rotating shaft 3, and the remaining sleeves 4 are rotatably connected to the rotating shaft 3. The adjacent sleeves 4 are connected through a torsion spring 5. The torsion spring 5 is an elastic element that can generate torque for the adjacent sleeves 4, which can be a torsion spring or a compression spring. The elastic force generated by the compression spring when compressed causes the adjacent sleeves 4 to generate torque. The rotating plate 6 is fixed on the sleeve 4, and the rotating plate 6 is staggered to form a spiral blade. The present invention can move the soil turning device to a specified position through the mobile frame 1, and the motor 7 drives the rotating shaft 3 to rotate through the transmission mechanism when working. The number of the rotating shafts 3 is 3, and the 3 rotating shafts 3 rotate under the connecting arm 2. The rotating shaft 3 is provided with a sleeve 4 and a rotating sheet 6. The lowest sleeve 4 is fixedly connected to the rotating shaft 3, and the remaining sleeves 4 are rotationally connected to the rotating shaft 3, and the adjacent sleeves 4 are connected by a torsion spring 5. When the rotating shaft 3 rotates, the lowest sleeve 4 and the rotating sheet 6 are driven to rotate, and the sleeve 4 drives the remaining rotating sheets 6 to rotate through the torsion spring 5. The torsion spring 5 can provide a strong elastic force, so that a small angle rotation occurs between the adjacent sleeves 4. In the initial state, the rotating sheets 6 are misplaced to form spiral blades. When working, the motor 7 drives the rotating shaft 3 to rotate, so that the spiral blades composed of several rotating sheets 6 are screwed into the soil below to complete the soil turning operation. In the initial state, the pitch of the spiral blades composed of several rotating sheets 6 is large. As the rotating shaft 3 rotates, the rotating sheet 6 is deflected by resistance in the soil. The greater the resistance, the greater the deflection angle, and finally the pitch of the spiral blades composed of several rotating sheets 6 is reduced, which can more easily penetrate into the hard soil. When the rotating piece 6 is screwed into the soil, the rotating piece 6 at the top is subject to less resistance, so the pitch of the spiral blade formed by the rotating piece 6 at the top is large, which can discharge the soil above upward, which is conducive to the rotating piece 6 at the bottom being screwed into the soil, and is convenient for turning the hard soil. The connecting arm 2 of the present invention is provided with multiple rotating shafts 3, and the multiple rotating shafts 3 work synchronously to turn the soil. The spiral blade formed by the rotating piece 6 with less resistance from the soil has a large pitch, which can turn out this part of the soil, thereby reducing the squeezing of the soil on other areas with greater resistance, and making it easier to screw into other areas with greater resistance.

[0026] Specifically, the bottom and top of the rotating piece 6 are planes, the side of the rotating piece 6 is arc-shaped, and the tops and bottoms of adjacent rotating pieces 6 fit together. When adjacent rotating pieces 6 deflect, the bottoms and tops remain closely fitted. The side of the rotating piece 6 is arc-shaped, which is convenient for screwing into the soil.

[0027] Specifically, a limiting slider 8 is provided at the upper end of the sleeve 4, and a limiting slot 9 is provided at the lower end of the sleeve 4. The limiting slider 8 of the sleeve 4 slides along the limiting slot 9 of another adjacent sleeve 4. After the relative rotation angle between the sleeves 4 reaches a preset value, the limiting slider 8 contacts the end of the limiting slot 9, thereby limiting the relative rotation between the sleeves 4 and preventing the relative rotation angle between the sleeves 4 from being too large.

[0028] Specifically, the transmission mechanism includes a driving gear 10 and a driven gear 11, the driving gear 10 is connected to the motor 7, the motor 7 is fixed on the connecting arm 2, the driving gear 10 is meshed with the driven gear 11, and the driven gear 11 is connected to the rotating shaft 3. When the motor 7 rotates, the driving gear 10 rotates, and the driving gear 10 drives the driven gear 11 to rotate. Since the driven gear 11 is connected to the rotating shaft 3, it drives the rotating shaft 3 to rotate, thereby rotating the rotating block on the rotating shaft 3 into the soil.

[0029] Specifically, the mobile frame 1 includes a frame body 12, rollers 13 and handrails 14, wherein the rollers 13 are rotatably connected to the frame body 12, the handrails 14 are connected to the rear end of the frame body 12, and the connecting arm 2 is connected to the front end of the frame body 12. The rollers 13 can facilitate the movement of the soil turning device on the ground, and the staff can push the frame body 12 to a designated area through the handrails 14.

[0030] Example 2

[0031] Please refer to the attached Figures 5-6 The difference between this embodiment and embodiment 1 is that the rotating shaft 3 is a hollow shaft with an inner cavity, the side wall of the rotating shaft 3 is provided with a plurality of first through holes 15, the inner wall of the sleeve 4 is provided with a plurality of limiting holes 16, the inner cavity of the rotating shaft 3 is provided with a push rod 17, the upper end of the push rod 17 is threadedly connected to the rotating shaft 3, the push rod 17 is arranged in an annular groove 18, the depth of the upper end of the annular groove 18 is less than the depth of the lower end, and a limiting rod 19 is slidably connected in the first through hole 15, and the limiting rod 19 is connected to the elastic element. When the push rod 17 is pushed downward, the side of the annular groove 18 of the push rod 17 pushes the limiting rod 19, so that the limiting rod 19 extends from the first through hole 15 and is inserted into the limiting hole 16, thereby limiting the rotation of the sleeve 4. The present invention can lock the rotating blades and prevent the rotating sheet 6 from rotating relative to the rotating shaft 3. When the restriction needs to be released, the push rod 17 can be pushed upward, and the limiting rod 19 can be pushed out of the limiting hole 16 under the action of the elastic element, thereby releasing the limiting effect.

[0032] Optionally, the elastic element includes a spring 20, a plunger 21 and a first bellows 22, the plunger 21 is slidably connected to the limiting hole 16, the first bellows 22 connects the plunger 21 and the inner wall of the limiting hole 16, the spring 20 is arranged in the first bellows 22, the spring 20 pushes the plunger 21 to move out of the limiting hole 16, and when the junction between the plunger 21 and the limiting rod 19 is aligned with the junction between the rotating shaft 3 and the sleeve 4, the sleeve 4 can rotate relative to the rotating shaft 3. The bellows is used to seal the bottom of the limiting hole 16 to prevent stains from entering the bottom of the limiting hole 16 and prevent it from getting stuck.

[0033] Specifically, the end of the plunger 21 facing the limiting rod 19 is hemispherical, so as to facilitate the misaligned rotation of the sleeve 4 and the rotating shaft 3.

[0034] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
