Description

Technical Field

[0001] This utility model belongs to the field of fruit tree planting technology, and in particular relates to a soil loosening and aeration device for fruit tree roots. Background Technology

[0002] Fruit trees are important perennial woody plants in the agricultural economy, and their fruits have edible, processing, medicinal, and ornamental value. Globally, fruit tree cultivation covers over 120 million hectares, generating an annual output value exceeding one trillion US dollars, involving hundreds of varieties such as apples, citrus, grapes, and bananas. With population growth, consumption upgrades, and climate change, the fruit tree industry faces the dual challenges of technological innovation and sustainable development.

[0003] Chinese Patent Publication No. CN 220368989 U discloses a soil loosening device for fruit tree planting. In this technical solution, an arc-shaped ring is placed around the root area of ​​the main trunk of the fruit tree. The ring is then pressed down to allow the loosening rod to enter the soil. Multiple loosening blades enter the soil. After the force applied to the arc-shaped ring is removed, the loosening blades, which expand outward under the reset action of the reset spring, rise with the reset of the arc-shaped ring. During the rise, the surrounding soil is turned over, thus achieving multi-point soil turning and greatly improving efficiency.

[0004] However, in this technical solution, the front end of the arc-shaped ring is open. When it is inserted into the soil around the trunk of the fruit tree, the front area is in an open state, lacking a corresponding structure to loosen the soil in that area. When the arc-shaped ring is pressed down to allow the soil-loosening blade to enter the soil and then reset and turn the soil, the soil at the front end cannot be turned over due to the lack of force, forming a soil-loosening blind zone. This leads to uneven distribution of nutrients in the soil, affecting the continuous supply of soil fertility and hindering the long-term healthy growth of the fruit tree. Utility Model Content

[0005] This utility model provides a soil loosening and aeration device for fruit tree roots, which aims to solve the problem that when the soil loosening head enters the soil and is reset to turn the soil under the pressure of the arc-shaped ring, the soil at the front end cannot be turned due to lack of force, thus forming a soil loosening blind zone.

[0006] This utility model is implemented as follows: a soil loosening and aeration device for fruit tree roots includes a rod body. An arc-shaped ring body is provided at the bottom of the front end of the rod body. Several soil loosening blades are provided at intervals at the bottom of the arc-shaped ring body. Receiving grooves are opened at both ends of the front part of the arc-shaped ring body. A first arc-shaped protrusion and a second arc-shaped protrusion that can extend to the outside of the arc-shaped ring body are respectively provided in the two receiving grooves. When the first arc-shaped protrusion and the second arc-shaped protrusion are unfolded, they form a circle with the arc-shaped ring body.

[0007] Both the outer ends of the first arc-shaped protrusion and the outer ends of the second arc-shaped protrusion are provided with a first soil loosening connector and a second soil loosening connector. When the first arc-shaped protrusion and the second arc-shaped protrusion are unfolded, the first soil loosening connector and the second soil loosening connector form a soil loosening knife for the front end of the pine cone tree.

[0008] Preferably, the bottom of the rod body is provided with a square groove, the side wall of the square groove is provided with a movable plate that can be raised and lowered, the two side walls of the movable plate are provided with foot pedals, and the outer end of each foot pedal is provided with a limit block.

First, the operator holds the handle of the rod and moves the device to the root of the fruit tree. Pressing down causes the ground nail to insert into the soil fixing device. Then, pressing the control button controls the electric slide rail, which drives the sliding block to unfold the first and second arc-shaped protrusions from the receiving groove into a circle. The first and second loosening connectors at their outer ends form a loosening blade, which, together with the loosening blade head on the arc-shaped ring, wraps around the fruit tree roots. The operator steps on the foot pedal, which, through the movable plate, moves the arc-shaped ring downwards, allowing the loosening blade to penetrate deep into the soil.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] First Embodiment

[0021] Please see Figures 1-3 This utility model provides a technical solution: a soil loosening and aeration device for fruit tree roots, including a rod body 1. An arc-shaped ring body 2 is provided at the bottom of the front end of the rod body 1, and a plurality of soil loosening blades 7 are provided at intervals at the bottom of the arc-shaped ring body 2. Receiving grooves are provided at both ends of the front part of the arc-shaped ring body 2. A first arc-shaped protrusion 4 and a second arc-shaped protrusion 5 that can extend to the outside of the arc-shaped ring body 2 are respectively provided in the two receiving grooves. When the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 are unfolded, they form a circle with the arc-shaped ring body 2.

[0022] When it is necessary to loosen the soil and aerate the roots of fruit trees, firstly, insert the arc-shaped ring 2 into the fruit tree, and then drive the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 to unfold, so as to wrap the entire fruit tree, ensuring that the roots of the fruit tree can be completely turned over, so that the nutrients in the soil are evenly distributed.

[0023] The outer ends of the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 are each provided with a first soil loosening connector 3 and a second soil loosening connector 6. When the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 are unfolded, the first soil loosening connector 3 and the second soil loosening connector 6 form a soil loosening knife for the front end of the pine cone tree.

[0024] In this embodiment, when the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 are fully extended, the first soil loosening connector 3 and the second soil loosening connector 6 form a soil loosening knife, which can loosen the soil at the rear end of the fruit tree root.

[0025] Please refer to Figure 2 and Figure 3Furthermore, a square groove 14 is provided at the bottom of the rod body 1, and a movable plate 17 is provided on the side wall of the square groove 14 for vertical movement. Foot pedals 12 are provided on both side walls of the movable plate 17, and a limit block 13 is provided at the outer end of each foot pedal 12. Several reciprocating springs 19 are provided between the square groove 14 and the movable plate 17. Several fixing members 18 are provided on the front side wall of the movable plate 17, and the other end of the fixing member 18 is fixedly connected to the rear side of the arc-shaped ring body 2.

[0026] In this embodiment, the operator first holds the rod 1 and moves the device to a suitable position in front of the fruit tree root. Then, the operator slowly pushes the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 so that they extend out of the receiving grooves at both ends of the front part of the arc-shaped ring 2 until the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 unfold and form a complete circle with the arc-shaped ring 2. At this time, the first loosening connector 3 and the second loosening connector 6 will automatically combine to form a loosening knife for the front end of the pine cone tree. The operator steps on the two foot pedals 12 with both feet respectively and applies downward pressure to make the movable plate 17 move downward in the square groove 14. Since the movable plate 17 is connected to the arc-shaped ring 2 through the fixing member 18, the arc-shaped ring 2 will move downward with the movable plate 17, so that the loosening knife head 7 and the combined loosening knife are inserted deeper into the soil. During the process of stepping down on the foot pedals 12, the reciprocating spring 19 will be compressed and store elastic potential energy. When the operator relieves pressure on their feet or lifts their feet, the reciprocating spring 19 releases elastic potential energy, pushing the movable plate 17 upward, which in turn drives the arc-shaped ring 2 and the loosening blade upward, realizing the reciprocating motion of the loosening blade in the soil, enhancing the loosening effect. The operator can control the stepping force and frequency of the foot pedal 12 according to the soil hardness and loosening depth to achieve the best loosening effect. At the same time, it is important to maintain balance during operation to avoid falling due to excessive force. After completing the loosening operation, the device is pulled out of the soil. Then, the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 are slowly pulled back into the receiving grooves at both ends of the front of the arc-shaped ring 2, restoring the device to its initial state.

[0027] Please refer to Figure 2 Furthermore, annular grooves are provided on both sides of the surface of the arc-shaped ring 2, and an electric slide rail 15 is provided in each annular groove. A sliding block 16 is slidably provided on the surface of each electric slide rail 15. The bottom of each sliding block 16 is fixedly connected to the upper surface of the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 respectively. A control button 11 is provided at the top of the rod 1.

[0028] In this embodiment, when it is necessary to loosen the soil around the fruit tree roots, the arc-shaped ring 2 is first inserted into the fruit tree roots. Then, the corresponding button on the control button 11 that controls the operation of the electric slide rail 15 is pressed, causing the electric slide rail 15 to move the sliding block 16 towards the front of the arc-shaped ring 2. Since the sliding block 16 is fixedly connected to the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 respectively, the first arc-shaped protrusion 4 and the second arc-shaped protrusion 5 will extend out from the receiving grooves at both ends of the front of the arc-shaped ring 2 as the sliding block 16 moves, so that the plurality of loosening blades 7 wrap around the fruit tree roots, and the soil can be loosened by pressing down on the device.

[0029] Please refer to Figure 1 Furthermore, handles 9 are provided at both ends of the top surface of the rod 1, and anti-slip sleeves 10 are provided on the surface of the handles 9.

[0030] In this embodiment, the operator holds the handles 9 at both ends of the top of the rod 1 with both hands to ensure that the palms are in full contact with the anti-slip sleeves 10. The anti-slip texture of the anti-slip sleeves 10 can increase the friction between the palms and the handles 9, preventing the handles 9 from slipping from the hands during operation.

[0031] When it is necessary to move the device, the operator can easily lift or push the device to the designated location by holding the handles 9 with both hands. During the movement, pay attention to the surrounding environment and avoid colliding with other objects.

[0032] Please refer to Figure 1 Furthermore, a number of ground nails 8 are provided at the bottom of the rod 1.

[0033] In this embodiment, when it is necessary to loosen the soil around the roots of the fruit trees, the device is first moved to the roots of the fruit trees, and then force is applied downwards to fix the device with ground nails 8 to ensure stability during the loosening process.

[0034] The working principle and usage process of this utility model are as follows: After the utility model is installed, the operator first holds the handle 9 of the rod body 1 and moves the device to the root of the fruit tree. Pressing down causes the ground nail 8 to be inserted into the soil fixing device. Then, the operator presses the control button 11 to control the electric slide rail 15, which drives the sliding block 16 to unfold the first and second arc-shaped protrusions from the receiving groove into a circle. The first and second loosening connecting parts at the outer end form a loosening knife, which cooperates with the loosening knife head 7 on the arc-shaped ring body 2 to wrap around the root of the fruit tree. The operator steps on the foot pedal 12, which drives the arc-shaped ring body 2 to move down through the movable plate 17, so that the loosening knife penetrates into the soil. The reciprocating spring 19 stores elastic potential energy when pressed down and releases it when the foot is lifted, pushing the arc-shaped ring body 2 to move up, thus loosening the soil and ventilating the root of the fruit tree.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
