Description

Technical Field

[0001] This utility model relates to the field of fruit tree planting technology, and in particular to a fruit tree weeding and soil loosening machine. Background Technology

[0002] During fruit tree planting, the exposed soil and abundant sunlight in the areas between fruit trees make them highly susceptible to weed growth. These weeds compete for water and nutrients with the tree roots, block ventilation and sunlight, and breed pests and diseases, severely hindering tree growth and fruit quality. Therefore, weeding and soil loosening between trees are frequently necessary. Conventional weeding between fruit trees primarily focuses on the narrow area between two trees, requiring the removal of surface weeds, cutting their roots, and loosening of compacted soil to improve aeration and ensure normal respiration and nutrient absorption for the shallow roots of the fruit trees. This is a routine orchard management task. Currently, most commonly used soil loosening machines employ rigid blades to cut and turn the soil for weeding and loosening. However, existing equipment relies on a fixed extension of the drive unit to adjust the loosening depth, making it unsuitable for soils of varying hardness. Furthermore, the undulating terrain of the orchard can cause the unit to bounce, resulting in significant fluctuations in loosening depth and poor operational stability. Utility Model Content

Multiple loosening teeth are arranged on the bottom surface of the base. An L-shaped frame is provided on the bottom surface of the base. A first motor is provided on the L-shaped frame. The output shaft of the first motor passes through the L-shaped frame and drives a blade. A tow hook is fixedly arranged at the front of the base. When the water tank moves with the slide towards the rear roller, it can increase the pressure between the loosening teeth and the ground.

[0006] Preferably, the driving mechanism includes a first support plate, a second support plate, a lead screw, a retractable sleeve, a driving gear, a driven gear, a rotating shaft, and a rocker handle. The first support plate and the second support plate are disposed opposite each other on the top surface of the base.

[0020] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0021] Example 1

[0022] See Figures 1 to 2This utility model provides a fruit tree weeding and soil loosening machine, including a base 1, a front roller 2, a rear roller 3, loosening teeth 9, and a drive mechanism. The front roller 2 is installed opposite to the front of the bottom surface of the base 1. The front roller 2 includes a U-shaped frame, which is fixedly installed at the front of the bottom surface of the base 1. The front roller 2 is rotatably located at the bottom of the U-shaped frame. The front roller 2 and the rear roller 3 cooperate to form the machine's walking support structure. During operation, it rolls along the orchard ground to reduce the machine's movement resistance. At the same time, it works with the rear roller 3 to maintain the machine's horizontal posture and ensure the stability of operation. The rear roller 3 is located at the rear of the bottom surface of the base 1 and is elastically connected to the base 1. A slide table 7 is slidably arranged on the top surface of the base 1 along the direction of the front roller 2 and the rear roller 3. A water tank 8 is fixedly arranged on the top surface of the slide table 7. A drive mechanism is arranged on the base 1 to drive the slide table 7 to move linearly in the front-back direction. Multiple loosening teeth 9 are arranged on the bottom surface of the base 1 and are arranged in a row at intervals along the longitudinal direction. An L-shaped frame 10 is provided on the bottom surface of the base 1. A first motor 11 is provided on the L-shaped frame 10. The output shaft of the first motor 11 passes through the L-shaped frame 10 and drives a blade 12. A tow hook 13 is fixedly arranged at the front of the base 1. When the water tank 8 moves with the slide table 7 toward the rear roller 3, it can increase the pressure between the loosening teeth 9 and the ground.

[0023] When the weeding and soil loosening machine is working, the tow hook 13 at the front of the base 1 connects to the traction machine, which moves along the area between the fruit trees. The front roller 2 and the elastically connected rear roller 3 support the machine body to move smoothly. The rear roller 3 adapts to the undulations of the ground in real time to avoid the machine body from shaking. Before the weeding and soil loosening machine is working, the water tank 8 is filled with water. At this time, the slide 7 is located in the middle of the base 1 and the water tank 8 is located on the top of the slide 7. Then, the traction machine is used to drag the weeding and soil loosening machine along the area between the fruit trees. The first motor 11 is started, and the first motor 11 drives the blade 12 to rotate at high speed, cutting the weeds between the trees from the roots. Multiple soil loosening teeth 9 installed on the bottom of the base 1 move with the traction machine to loosen the soil, completing the integrated weeding and soil loosening operation. Meanwhile, the operator observes the soil loosening condition of the loosening teeth 9. When the orchard soil is hard, the drive mechanism drives the slide 7 to move the water tank 8 backward, increasing the distance between the water tank 8 and the front roller 2. According to the lever principle, with a fixed distance between the loosening teeth 9 and the front roller 2, the soil-penetrating pressure of the loosening teeth 9 increases accordingly. When the weeding and loosening machine moves at a certain speed, the loosening teeth 9 loosen the soil to a certain depth. If it is necessary to further increase the soil-penetrating depth, the drive mechanism is activated, driving the slide 7 to move the water tank 8 backward slowly, increasing the soil-penetrating depth until the required depth is reached. Then, the drive mechanism is stopped, and the water tank 8 remains in a fixed position. Conversely, when the orchard soil is soft, the drive mechanism is activated, driving the slide 7 to move the water tank 8 forward, decreasing the distance between the water tank 8 and the front roller 2. According to the lever principle, with a fixed distance between the loosening teeth 9 and the front roller 2, the soil-penetrating pressure of the loosening teeth 9 decreases accordingly, thus reducing the soil-penetrating depth and preventing the loosening teeth 9 from damaging the shallow root system of the fruit trees by going too deep. This weeding and soil loosening machine uses a drive mechanism to move the slide 7 and water tank 8 back and forth, eliminating the need for additional hydraulic pressurization equipment and enabling stepless adjustment of the loosening depth. It is suitable for soils of varying hardness. The front blade 12 cuts weeds and, in conjunction with the loosening teeth 9, turns them over. The chopped weeds are then turned over and buried as green manure, improving soil aeration.

[0024] Preferably, the drive mechanism includes a first support plate 14, a second support plate 15, a lead screw 16, a telescopic sleeve 17, a driving gear 19, a driven gear 18, a rotating shaft 21, and a rocker handle 22. The first support plate 14 and the second support plate 15 are disposed opposite each other on the top surface of the base 1. The lead screw 16 is rotatably disposed between the first support plate 14 and the second support plate 15. One end of the lead screw 16 is rotatably connected to the second support plate 15, and the other end passes through the first support plate 14 and is connected to the driven gear 18. A slide table 7 is disposed on the lead screw 16 and is threadedly connected to the lead screw 16. A lead screw 16 and nut transmission pair are formed. For each rotation of the lead screw 16, the slide table 7 moves forward or backward by one pitch along the axis of the lead screw 16. The telescopic sleeve 17 is fitted on the lead screw 16. The telescopic sleeve 17 is fitted on the outside of the lead screw 16, which serves to prevent dust and mud, and can also extend and retract with the slide table 7 to ensure that the lead screw 16 operates smoothly for a long time. The rotating shaft 21 is rotatably mounted on the support plate 14. The driving gear 19 is fixedly fitted on the rotating shaft 21 and meshes with the driven gear 18. The rocker handle 22 is mounted on the rotating shaft 21.

[0025] When the drive mechanism is working, during operation adjustment, the operator turns the crank handle 22, which drives the rotating shaft 21 to rotate. The driving gear 19 fixed on the rotating shaft 21 rotates accordingly and meshes with the driven gear 18 to reduce its rotation speed. The driven gear 18 is fixedly connected to the lead screw 16, so that the lead screw 16 obtains a smooth, low-speed, high-torque output, which in turn drives the slide table 7 and water tank 8 to move slowly and precisely in the front-back direction, changing the position of the machine's center of gravity. Turning the crank handle 22 clockwise causes the lead screw 16 to rotate forward, the slide table 7 to move forward, the center of gravity to shift forward, and the soil loosening pressure to decrease. Turning the crank handle 22 counterclockwise causes the lead screw 16 to rotate in reverse, the slide table 7 to move backward, the center of gravity to shift backward, and the soil loosening pressure to increase. This achieves stepless and continuous adjustment of the soil loosening pressure. The whole process is simple to operate and has operational stability.

[0026] Preferably, the drive mechanism also includes a housing 20, which is fixedly installed on the outside of the support plate 14. The drive gear 19 and the driven gear 18 are located inside the housing 20. One end of the rotating shaft 21 passes through the housing 20 and is connected to the crank handle 22. The drive gear 19 has fewer teeth and the driven gear 18 has more teeth, resulting in a smaller transmission ratio, which makes it easier for the operator to operate the crank handle 22.

[0027] When the drive mechanism is working, the operator manually operates the crank handle 22, causing the crank handle 22 to rotate and drive the rotating shaft 21 to rotate. The driving gear 19 and the driven gear 18 mesh with each other, transmitting power to the driven gear 18. The rotation of the driven gear 18 drives the lead screw 16 to rotate, thereby driving the slide table 7 to move. In addition to providing structural support, the housing 20 encloses the driving gear 19 and the driven gear 18 in a sealed space, effectively preventing field dust, mud, weed debris, and rainwater from entering the gear meshing area, avoiding gear wear, jamming, or corrosion, extending the service life of the gear set, reducing the frequency of daily maintenance, and ensuring long-term stable operation in the complex and dusty environment of the orchard, ensuring smooth transmission when the crank handle 22 adjusts the position of the slide table 7.

[0028] Preferably, the bottom surface of the base 1 is provided with a rectangular slide groove 5, and the top of the rear roller 3 is fixedly provided with a rectangular slide rod 4. The rectangular slide rod 4 is slidably disposed in the rectangular slide groove 5. A helical spring 6 is provided in the rectangular slide groove 5. One end of the helical spring 6 is connected to the base 1, and the other end is connected to the rectangular slide rod 4.

[0029] When the weeding and loosening machine is working, the front roller 2, loosening teeth 9, and rear roller 3 are in contact with the ground. The rear roller 3 slides up and down in the rectangular groove 5 of the base 1 through the rectangular slide rod 4 to achieve vertical displacement compensation. The helical spring 6 always pushes the rectangular slide rod 4 to keep the rear roller 3 close to the ground. When the ground is raised, the rear roller 3 is pushed up by the upward reaction force, which pushes the slide rod to move up and the spring is compressed to prevent the machine body from being lifted. When the ground is sunken, the spring rebounds and pushes the slide rod to move down, so that the rear roller 3 always keeps in contact with the ground, thereby adapting to the undulation of the orchard ground, reducing the machine body's bumps and tilts, ensuring that the whole machine travels smoothly and the loosening teeth 9 penetrate the soil at a uniform and stable depth.

[0030] Preferably, the system also includes a support plate 31, a rotating shaft 32, a connecting rod 23, and a hydraulic rod 24. The support plate 31 is disposed opposite to the bottom surface of the base 1. The rotating shaft 32 is rotatably disposed on the support plate 31, and both ends of the rotating shaft 32 are rotatably connected to the support plate 31. Multiple loosening teeth 9 are spaced apart on the rotating shaft 32 and spaced apart on the connecting rod 23. The bottom surface of the base 1 is provided with a receiving groove 25, and the hydraulic rod 24 is disposed in the receiving groove 25. The hydraulic rod 24 is hinged in the receiving groove 25, and the telescopic end of the hydraulic rod 24 is hinged to the connecting rod 23.

[0031] When the weeding and loosening machine is working, the hydraulic rod 24 is activated first. The extension and retraction of the hydraulic rod 24 pushes the connecting rod 23 to swing, which drives the rotating shaft 32 to rotate on the support plate 31. This allows all the loosening teeth 9 to adjust their entry angle and depth into the soil synchronously, adapting to different soil hardness and operational needs. After the operation is completed, the loosening teeth 9 can be retracted upwards, reducing the space occupied by the whole machine and facilitating transportation and storage. The machine has a compact structure and flexible adjustment, effectively improving the adaptability and ease of use of loosening operations.

[0032] Preferably, the system also includes a water pump 26, a water suction pipe 27, a water outlet pipe 28, and a nozzle 29. The water pump 26 is fixedly installed on the top surface of the water tank 8. The water inlet end of the water pump 26 is connected to the water suction pipe 27. The end of the water suction pipe 27 away from the water pump 26 passes through the water tank 8 and extends to the bottom of the water tank 8. The nozzle 29 is located below the base 1 and is connected to the water pump 26 through the water outlet pipe 28.

[0033] When the weeding and soil loosening machine is working, the water pump 26 starts and draws clean water from the bottom of the water tank 8 through the water pipe 27. The water is then delivered to the nozzle 29 below the base 1 through the water outlet pipe 28. The nozzle 29 sprays water mist evenly onto the work area, which effectively suppresses dust generated during soil loosening and weeding, improves the orchard working environment, and prevents dust from contaminating the fruit. On the other hand, it moderately moistens the surface soil, reduces wear on the loosening teeth 9, and promotes the decomposition of weeds, further improving the weeding and soil loosening effect. The overall structure is highly integrated and the water supply is stable, eliminating the need for an additional independent water supply device, thus reducing equipment costs and structural complexity.

[0034] Example 2

[0035] See Figure 1 The difference from Example 1 is as follows:

[0036] Preferably, a second motor 30 is also included. The second motor 30 is fixedly installed on the side of the support plate 14. The output shaft of the second motor 30 is connected to the rotating shaft 21. When working, the second motor 30 is started, and the rotation of the second motor 30 drives the rotating shaft 21 to rotate, replacing the operation of the manual crank 22, so as to realize the forward and backward movement of the slide table 7. The movement of the slide table 7 drives the movement of the water tank 8, thereby adjusting the distance between the water tank 8 and the front roller 2. The second motor 30 adopts a stepper motor model with controllable rotation angle, and the speed adjustment is uniform and stable, reducing the labor intensity of the operator. At the same time, it can be used with the manual crank 22 to form a manual and electric dual drive mode, further improving the convenience of use.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
