Description

Technical Field

[0001] The invention belongs to the technical field of flower and tree cultivation soil loosening equipment, and in particular relates to a small tree soil loosening machine. Background Art

[0002] In the process of cultivating flowers and trees, it is very important and necessary to loosen the soil at the roots of the trees. Because the soil tends to clump over time, the roots of flowers and trees are prone to lack of oxygen in the clumping soil for a long time, which reduces the root capacity of the crops, affects the absorption of nutrients, and causes the crops to fail to develop normally. Loosening the soil can make the soil loose, increase the air permeability of the soil, promote the respiration of the plant roots, and promote the roots to go deep, which is beneficial to the growth of the roots and prevents the plants from lodging. In spring, loosening the soil can also conserve moisture, increase the ground temperature, and prevent frostbite on trees.

[0003] At present, there are two main ways to loosen the soil: manual loosening and mechanical loosening. Manual loosening is inefficient and heavily dependent on the experience of workers, otherwise it is easy to damage the roots of trees. However, there are still many problems with the loosening equipment on the market: 1. Some products loosen the soil through a soil-turning blade rotating around an axis. This kind of loosening mechanical structure will damage the roots of trees, so it can only loosen the soil on the front surface of flowers and trees with deep roots, which is very limited. 2. Some products loosen the soil near the roots of flowers and trees by driving a claw-shaped loosening mechanism through a vibration mechanism. The roots and stems of trees pass through the gaps between the claws. Vibration loosening avoids damaging the roots of flowers and trees, but the disadvantage of this loosening structure is that the claw spacing is fixed, so it can only loosen the soil for flowers and trees with matching root diameters, and because the vibration range is small, it is impossible to crush soil blocks with smaller block diameters, so the loosening effect is poor.

[0004] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Summary of the invention

[0005] In view of the deficiencies in the above-mentioned prior art, the present invention provides a small tree loosening machine, which loosens the soil by means of loosening claws that can vibrate and open and close. It can loosen the soil of flowers and trees with different root diameters and has a wide range of applications. The loosening claws can crush soil blocks that cannot be broken by vibration, thereby greatly improving the loosening effect.

[0010] A limiting flange is provided on the outer surface of the offset ring seat, and a corresponding limiting groove is provided in the shell. The limiting groove and the connecting assembly cooperate to enable the offset ring seat and the loosening mechanism to move back and forth in the horizontal direction. The offset ring seat is through-through, and the assembly block is located at the center of the offset ring seat. A limiting groove is provided on the inner wall of the offset ring seat, and a rotating end ring of the claw finger is provided with a rotating tooth, and the rotating tooth and the limiting groove are meshed and assembled.

[0040] refer to Figures 1 to 8 A small tree scarifier comprises a gripping portion 1, a rod portion 2 and a working portion 3 which are sequentially connected and assembled. The working portion 3 comprises a shell 4 in which a vibration block 5, a scarifying mechanism 6 and an offset ring seat 7 are installed.

[0041] The vibration block 5 is provided with a connecting assembly, which is connected to the loosening mechanism 6 and the offset ring seat 7. The vibration block 5 is driven by a cam 8, and the cam 8 is connected to a driving motor 81. A push rod 53 is provided below the vibration block 5. A first elastic member 54 for resetting is provided between the vibration block 5 and the housing 4. The first elastic member 54 and the cam 8 drive and cooperate to enable the vibration block 5 to reciprocate up and down.

[0042] The loosening mechanism 6 includes an assembly block 61 and a loosening claw 62, and the assembly block 61 is located below the top rod 53. The loosening claw 62 extends out of the housing 4, and the loosening claw 62 includes a plurality of claw fingers 621, and the claw fingers 621 are rotatably mounted on the assembly block 61. A second elastic member 63 for resetting is installed between the assembly block 61 and the offset ring seat 7. The top rod 53 and the second elastic member 63 cooperate to enable the loosening mechanism 6 to reciprocate up and down.

[0043] A limiting flange 71 is provided on the outer surface of the offset ring seat 7, and a corresponding limiting groove 41 is provided in the shell 4. The limiting groove 41 cooperates with the connecting assembly to enable the offset ring seat 7 and the loosening mechanism 6 to move back and forth in the horizontal direction. The offset ring seat 7 is through-through in the middle, and the assembly block 61 is located at the center of the offset ring seat 7. A limiting groove 72 is provided on the inner wall of the offset ring seat 7. A rotating tooth 622 is provided on the rotating end ring of the claw finger 621, and the rotating tooth 622 is meshed and assembled with the limiting groove 72. When the assembly block 61 vibrates up and down, the loosening claw 62 opens and closes with the cooperation of the rotating tooth 622 and the limiting groove 72.

[0044] The specific working principle of this embodiment is:

[0045] The driving motor 81 drives the cam 8. Under the reset action of the first elastic member 54, the cam 8 rotates to make the vibration block 5 vibrate back and forth up and down. Under the transmission action of the connecting assembly, the loosening mechanism 6 and the offset ring seat 7 move back and forth in the horizontal direction. During this period, when the vibration block 5 moves downward, the top rod 53 located on the vibration block 5 pushes the assembly block 61 downward, and the loosening claw 62 opens under the cooperation of the rotating teeth 622 and the limiting groove 72. When the vibration block 5 moves upward, the assembly block 61 moves upward under the reset action of the second elastic member 63, and the loosening claw 62 is closed under the cooperation of the rotating teeth 622 and the limiting groove 72.

[0046] With the cooperation of the above-mentioned structure, during the loosening process, the loosening claws 62 can vibrate back and forth in the horizontal direction to loosen the soil near the tree roots. At the same time, the loosening claws 62 can open and close in coordination with the vibration. The continuously opening and closing loosening claws 62 can crush harder soil blocks and can fully stir the soil within the loosening working range, so that the loosening effect is greatly improved compared to simple vibration loosening.

[0047] As a specific embodiment, the connection assembly includes a first connection member 51 and a second connection member 52 .

[0048] The first connecting member 51 is connected to the assembly block 61: the first connecting member 51 includes a first connecting rod 511 which is arranged obliquely, one end of the first connecting rod 511 is connected to the lower surface of the vibration block 5, and the other end of the first connecting rod 511 is connected to the upper surface of the assembly block 61. The up and down reciprocating vibration of the vibration block 5 provides a driving force for the assembly block 61 to reciprocate left and right through the first connecting rod 511.

[0049] The second connecting member 52 is connected to the offset ring seat 7: the second connecting member 52 includes two second connecting rods 521, one end of which is connected to each other, and the connection angle of the second connecting rods 521 is 90°. A fixed shaft 522 is installed at the connection of the second connecting rods 521, and the fixed shaft 522 is assembled and connected to the housing 4. The up and down reciprocating vibration of the vibration block 5 provides a driving force for the left and right reciprocating movement of the offset ring seat 7 through the second connecting rods 521.

[0050] In particular, the first connecting rod 511 and the second connecting rod 521 are elastic telescopic rods, so that the first connecting rod 511 and the second connecting rod 521 can change in length according to the movement, thereby preventing the assembly block 61 and the offset ring seat 7 from getting stuck when they move back and forth left and right.

[0051] Compared with the above embodiment, the effect of this embodiment is that the assembly block 61 and the offset ring seat 7 are respectively connected to the vibration block 5, preventing the assembly block 61 and the offset ring seat 7 from interfering with each other when moving back and forth left and right, and preventing jamming due to uneven force.

[0052] As a specific embodiment, the vibration block 5 is provided with a limiting protrusion 55, the housing 4 is provided with a reset limiting groove 42 matched with the limiting protrusion 55, the first elastic member 54 is installed in the reset limiting groove 42, one end of the first elastic member 54 is connected to the surface of the limiting protrusion 55, and the other end of the first elastic member 54 is connected to the surface of the reset limiting groove 42. The first elastic member 54 enables the vibration block 5 to reset itself.

[0053] Compared with the above-mentioned embodiment, the effect of this embodiment is that the assembly of the limiting protrusion 55 and the reset limiting groove 42 can prevent the vibration block 5 from being offset during the vibration process, resulting in the loosening mechanism 6 and the offset ring seat 7 being stuck.

[0054] As a specific embodiment, the claw finger 621 is in an arc shape, so that the center of the loosening claw 62 can leave enough space for the tree roots to avoid damaging the tree roots when loosening the soil. At the same time, in order to avoid deformation of the claw finger 621 structure, the cross section of the claw finger 621 is in a cross shape, so that the claw finger 621 can have sufficient structural strength.

[0055] As a specific embodiment, the housing 4 is provided with a rotating shaft, and the rotating shaft is provided with a pedal 43. The user can provide assistance to the tiller to break the soil through the pedal 43, thereby improving the tillering efficiency. The grip portion 1 includes a control seat 11 assembled on the rod portion 2, and a control panel 111 is provided on the control seat 11. Handles 12 are provided at both ends of the control seat 11. The user can conveniently control the vibration speed of the tiller through the control panel 111.

[0056] Compared with the prior art, the present application loosens the soil by means of loosening claws 62 that can vibrate and open and close, and can loosen the soil for flowers and trees with different root diameters, and has a wide range of applications. The loosening claws 62 can crush soil blocks that cannot be broken by vibration, thereby greatly improving the loosening effect.
