The nozzle 605 is provided to spray water in the form of a thin stream, which can better penetrate into the soil, quickly and effectively soften the soil, and create good conditions for digging operations. The hydraulic rod 606 can be provided to adjust the height of the water storage plate 604 and the fixed rod 607. According to different soil conditions and operation requirements, the nozzle 605 can be adjusted to the optimal water spraying position to improve the soil softening effect. The fixed rod 607 can be provided to fix it to the soil to ensure that the water storage plate 604 will not shake or tilt during operation, thereby ensuring the smooth progress of the water spraying operation.

[0031] Specifically, such as Figure 3 、 Figure 5 As shown, the softening mechanism 7 includes a limiting groove 701, a threaded rod 702, a motor 703, a slide groove 704, a limiting rod 705, a slider 706 and a plowing harrow 707, and the limiting groove 701 is opened on the front side of the bottom of the water storage plate 604.

[0032] Specifically, such as Figure 3 、 Figure 5As shown, the threaded rod 702 is rotatably connected to the inner side of the limiting groove 701, the motor 703 is bolted to the left side of the water storage plate 604, the left side of the threaded rod 702 passes through the water storage plate 604 and is bolted to the output end of the motor 703, and the slide groove 704 is opened on the rear side of the bottom of the water storage plate 604.

[0033] Specifically, such as Figure 3 As shown, the limiting rod 705 is bolted to the inner side of the slide groove 704, the slider 706 is bolted to both sides of the top of the harrow 707, the slider 706 is threadedly connected to the surface of the threaded rod 702, and the slider 706 is slidably connected to the surface of the limiting rod 705.

[0034] In this embodiment, the limiting groove 701 is provided to provide space for installation and rotation of the threaded rod 702, and the slider 706 is also provided to limit the position to ensure that the harrow 707 can move in the correct direction during operation. The threaded rod 702 is rotated under the drive of the motor 703, which drives the slider 706 and the harrow 707 to move, thereby realizing the harrow 707 operation on the soil, further softening the soil, improving the softness of the soil, and creating better conditions for the work of the digging machine. The motor 703 is provided to provide power for the rotation of the threaded rod 702, thereby improving the efficiency and quality of soil softening. The slide groove 704 is provided to provide a sliding track for the slider 706, thereby ensuring that the slider 706 can move smoothly. The stability of the harrow 707 during movement is ensured, and at the same time, it also plays a certain limiting role on the slider 706 to prevent the slider 706 from getting off the track. By setting the limiting rod 705 to cooperate with the slide groove 704, the moving direction of the slider 706 is limited to ensure that the slider 706 can only move in a specific direction, thereby ensuring the working stability of the harrow 707. By setting the slider 706 to connect the harrow 707 and the threaded rod 702, the rotational motion of the threaded rod 702 is converted into the linear motion of the harrow 707, and the harrow 707 operation of the soil is realized. By setting the harrow 707 to harrow the soil, the hard lumps in the soil are broken, the soil is further softened, and the soil is made looser, which is convenient for the excavator to perform excavation operations.

[0035] Specifically, such as Figure 5 As shown, the bottom of the motor 703 is bolted to a base 9 , and the side of the base 9 away from the motor 703 is bolted to the left side of the water storage plate 604 .

[0036] Specifically, such as Figure 4 As shown, a sealing ring 10 is bolted to the top of the pressure pump 602 , and the side of the sealing ring 10 away from the pressure pump 602 is bolted to the inner side of the water tank 601 .

[0037] In this embodiment: by setting the base 9, a stable installation foundation is provided for the motor 703, ensuring that the motor 703 will not shake or shift during operation, thereby ensuring that the motor 703 can stably drive the threaded rod 702 to rotate, so that the softening mechanism 7 can operate normally, and by setting the sealing ring 10, the water in the water tank 601 is effectively prevented from leaking from the connection when the pressure pump 602 is working, ensuring that the pressure pump 602 can normally pump water out of the water tank 601 and transport it to the threaded hose 603 and the water storage plate 604, thereby improving the working efficiency and reliability of the water spraying mechanism 6.

[0038] Specifically, such as Figure 2 As shown, the bottom of the fixing rod 607 is set to be conical, and the surface of the fixing rod 607 is coated with anti-corrosion paint.

[0039] Specifically, such as Figure 4 As shown, the surface of the handle 5 is covered with a protective cover 11 , and the surface of the protective cover 11 is engraved with anti-slip patterns.

[0040] In this embodiment: by setting the bottom of the fixing rod 607 to be conical, the conical design makes it easier for the fixing rod 607 to be inserted into the soil, thereby enhancing the stability of the hydraulic rod 606 during operation and preventing the water storage plate 604 from shaking. By providing an anti-corrosion coating, the fixing rod 607 can be protected from erosion by moisture, chemicals, etc. in the soil, thereby extending the service life of the fixing rod 607 and ensuring that the water spraying mechanism 6 can work stably in various environments. By providing a protective cover 11, a comfortable grip is provided for the operator, reducing wear and fatigue on the hand when operating the handle 5 for a long time. By providing anti-slip grooves, the friction between the hand and the handle 5 is increased, so that the operator can hold the handle 5 more firmly when pushing the cart 1, better control the moving direction and speed of the equipment, and improve the safety and stability of the operation.

[0041] Working principle: First, the user holds the handles 5 on both sides of the cart 1 and moves the cart 1 to the desired location for digging holes for fruit tree planting. When it reaches the appropriate position, if the user observes that the soil is relatively hard and needs to be softened, the hydraulic rod 606 can be started. The hydraulic rod 606 can accurately adjust the height of the water storage plate 604 and the fixed rod 607 according to different soil conditions and work requirements, and adjust the nozzle 605 to the optimal water spraying position. After adjusting the position, as the hydraulic rod 606 drives the water storage plate 604 to descend, the conical design of the bottom of the fixed rod 607 enables it to be easily plugged and fixed to the soil. Then, the user turns on the power to start the pressure pump 602. The pressure pump 602 provides strong pressure for the water spray, draws out the water inside the water tank 601, and guides the pressurized water to the inside of the water storage plate 604 through the threaded hose 603. The water storage plate 604 fully exerts its role in dispersing the water flow, so that the water can be evenly distributed from Multiple nozzles 605 spray out, and the nozzles 605 spray water in the form of a thin stream, which can efficiently penetrate into the soil and quickly soften the soil. At the same time, the user turns on the power to start the motor 703. After the motor 703 is started, it drives the threaded rod 702 bolted to its output end to rotate stably in the limit groove 701. The slider 706 is threadedly connected to the surface of the threaded rod 702 on the one hand, and is slidably connected to the limit rod 705 in the slide groove 704 on the other hand. Under the rotation of the threaded rod 702, the slider 706 drives the harrow 707 to move, and the harrow 707 performs harrowing operations on the soil, which can effectively break up hard lumps in the soil and further soften the soil. Finally, after the soil softening is completed, the user drives the threaded rod 702 to reverse through the motor 703, thereby driving the harrow 707 to reset, and then turns off the pressure pump 602 to stop spraying water. At this time, the user turns on the power to start the excavator body 3 and performs excavation operations on the softened soil.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
