Description

Technical Field

[0001] The present invention relates to the technical field of vegetable planting, and specifically to a soil loosening and weeding device for vegetable planting. Background Art

[0002] After vegetables are planted, as the growth and development process of the vegetables progresses, weeds often inevitably grow in the vegetable planting land. The growth and spread of these weeds will have extremely adverse effects on the growth of vegetables in many aspects. Therefore, it is often necessary to use a soil loosening and weeding device to loosen the soil in the vegetable planting land and at the same time remove the weeds in the land.

[0003] Currently, when loosening soil and weeding vegetable fields, in addition to the traditional and time-consuming hoe, semi-automatic soil loosening and weeding devices are often used for soil loosening and weeding operations. However, the terrain structure of vegetable planting lands shows significant diversity. Among them, some vegetable planting lands adopt an alternating pattern of furrows and ridges. This layout helps to optimize the drainage performance of the soil, increase the light-receiving area of the soil, and improve the air permeability of the soil, which has unique advantages for the planting of specific types of vegetables. While some other vegetable planting lands adopt a relatively flat overall pattern, which is convenient for large-scale mechanized operations and unified planting management. Most of the existing soil loosening and weeding devices are designed and developed based on relatively flat terrain conditions. When facing vegetable planting lands with an alternating pattern of furrows and ridges, their structures and functions expose insurmountable limitations. For example, the adjustment ranges of the working parts of the device in terms of height and angle are relatively limited. When applied to the ridges, it may not be able to accurately fit the inclinations of both the furrow surface and the ridge surface simultaneously for effective soil loosening and weeding operations, resulting in incomplete weeding or unnecessary damage to the ridge part. These problems not only greatly reduce the working efficiency of the existing soil loosening and weeding devices in vegetable planting lands with an alternating pattern of furrows and ridges, but also may have a negative impact on the growth environment of vegetables due to poor operation effects, such as damaging the roots of vegetables and leaving a large number of weeds. Therefore, we propose a soil loosening and weeding device for vegetable planting. Summary of the Invention

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1: Please refer to Figures 1 - 9 As shown in the figure, the present invention provides a technical solution: a soil loosening and weeding device for vegetable planting, including a vehicle frame 1. The vehicle frame 1 serves as the basic structure of the entire device and plays a role in stable support. Driving wheels 2 are installed at the bottom end of the vehicle frame 1. The driving wheels 2 can provide power for the movement of the device, enabling it to move flexibly in the vegetable planting field. Moreover, a handrail is connected to one side of the vehicle frame 1. The design of the handrail facilitates the staff to grasp and apply force during the operation process to better control the running direction of the device. In addition, a switch can be installed on the handrail. The position of the switch is set so that the staff can easily touch and operate it when operating the device, thereby precisely controlling the start, stop, and switching of various functions of the device, greatly improving the operation convenience and work efficiency of the staff, making the entire device more handy during actual use, and capable of efficiently completing the tasks of soil loosening and weeding.

[0040] In addition, the soil loosening and weeding device for vegetable planting further includes a lifting assembly 5, mounting seats 8, and a deformation assembly 9. There are two mounting seats 8. The two mounting seats 8 are arranged front and back. The soil loosening teeth 3 and rake teeth 4 are respectively installed at the bottom ends of the two mounting seats 8. The rake teeth 4 are arranged at the rear side of the operation of the soil loosening teeth 3 to achieve soil loosening first and then weeding. Each mounting seat 8 includes a fixed seat 81 and two movable seats 82. The two movable seats 82 are hinged to both ends of the fixed seat 81. The lifting assembly 5 is installed on the vehicle frame 1, and a connecting column 7 is connected between the lifting assembly 5 and the mounting seats 8. The two mounting seats 8 are synchronously lifted and lowered through the lifting assembly 5 to adjust the depth of the soil loosening teeth 3 and the rake teeth 4 penetrating into the soil layer. The deformation assembly 9 is arranged on the mounting seats 8, and the deformation assembly 9 is used to achieve the synchronous upward or downward deflection of the two movable seats 82, so that the movable seats 82 on both sides of the fixed seat 81 are synchronously deflected by the same angle to cope with the soil loosening and weeding of the ditch and ridge parts of different vegetable planting lands.

[0041] Among them, refer to Figure 5As shown in the figure, the lifting assembly 5 includes a connecting plate 51, a first motor 52 and a first lead screw 53. The first motor 52 is a reversible motor. There are two first lead screws 53. Both of the two first lead screws 53 vertically penetrate the vehicle frame 1 through bearings. The first motor 52 is installed on the vehicle frame 1, and the output end of the first motor 52 is connected to the top end of one of the first lead screws 53. A first lead screw nut seat 54 is installed outside the first lead screw 53. The end of the first lead screw nut seat 54 is connected to the middle of the side wall of the connecting plate 51. The lower end surface of the connecting plate 51 is connected to the top end of the connecting column 7. The two first lead screws 53 are connected by a linkage member 55.

[0042] The linkage member 55 includes pulley wheels 551 respectively fixed outside the two first lead screws 53. A belt 552 is provided between the two pulley wheels 551. When the first motor 52 is started, its output end begins to operate and drives the connected first lead screw 53 to rotate. At the same time, by means of the transmission connection established by the belt 552, the power can be transmitted to the first lead screw 53 with a pulley wheel 551 installed on the other side, so as to ensure that the two first lead screws 53 rotate synchronously. During the synchronous rotation of the first lead screws 53, the two first lead screw nut seats 54 will perform synchronous lifting and lowering movements along the axial direction of the lead screw due to the effect of the thread. The soil loosening teeth 3 and the harrow teeth 4 are respectively firmly connected and installed to the corresponding first lead screw nut seats 54. In this way, as the first lead screw nut seats 54 lift and lower synchronously, the soil loosening teeth 3 and the harrow teeth 4 can also accurately perform synchronous lifting and lowering actions. Through this ingenious mechanical transmission design, not only can the lifting control of the soil loosening teeth 3 and the harrow teeth 4 be realized efficiently, but also the stability and coordination of the entire device during operation are ensured, providing a reliable and accurate action execution basis for subsequent operations such as soil loosening and weeding in the vegetable planting land.

[0043] Refer to Figures 6 - 8 As shown in the figure, the deformation assembly 9 includes a third motor 91 installed on the outer wall of the fixed seat 81. The third motor 91 is a reversible motor. The fixed seat 81 is hollow inside. Concave grooves are also provided at both ends of the fixed seat 81 to avoid blocking the rotation of the movable seat 82. The output end of the third motor 91 is connected to a second connecting rod 95. A rotatable third connecting rod 96 is installed inside the fixed seat 81 and beside the second connecting rod 95. Second grooves 92 are opened at one end of each of the two movable seats 82 facing the fixed seat 81. A first connecting rod 93 is fixed inside the second grooves 92. Sprocket wheels 94 are respectively fixed outside the first connecting rod 93, the second connecting rod 95 and the third connecting rod 96. Chain wheels 94 on the two first connecting rods 93 and the adjacent sprocket wheels 94 are respectively connected by chains 97 in a transmission manner. And a gear transmission member 98 is provided between the second connecting rod 95 and the third connecting rod 96. The gear transmission member 98 is used to realize the simultaneous opposite deflection of the second connecting rod 95 and the third connecting rod 96, so that the two movable seats 82 deflect upward or downward synchronously.

[0044] Among them, the gear connecting member includes a first gear 981 fixed to the outside of the second connecting rod 95 and a second gear 982 fixed to the outside of the third connecting rod 96, and the second gear 982 is meshed and connected to the first gear 981.

[0045] Through the above, in actual use: The staff can hold the handrail and use the equipment to move in the vegetable planting field for tilling and weeding. Before performing the tilling and weeding operation, when facing the weeding task of the vegetable planting field with alternately distributed furrows and ridges, the staff will first operate the switch installed on the handrail of the equipment to start the third motor 91, and use the third motor 91 to drive the second connecting rod 95 connected thereto to rotate together. As the second connecting rod 95 rotates, the sprocket 94 installed on it also starts to rotate, and then drives the connected chain 97 to start circulating. Under the pulling action of the chain 97, the movable seat 82 on one side will receive an upward pulling force and thus start to deflect upward. At the same time, during the rotation of the second connecting rod 95, the first gear 981 installed on it also rotates synchronously. Because the first gear 981 meshes with the second gear 982, the rotation of the second gear 982 will drive the third connecting rod 96 and the sprocket 94 thereon to rotate together. Similarly, this sprocket 94 will also apply an upward pulling force to the movable seat 82 on the other side through the connected chain 97, making it deflect upward synchronously. Through such a transmission system, the inclination angles of the two movable seats 82 can be adapted to the slopes of the ridges, thus laying a solid foundation for subsequent efficient and accurate tilling and weeding operations on the slopes of the ridges.

[0046] When it comes to a vegetable planting field without alternately distributed furrows and ridges, at this time, the movable seat 82 and the fixed seat 81 are in a straight line, and the movable seat 82 does not need to perform complex deflection operations to adapt to a specific slope.

[0047] In summary, this deformable design can fully consider the special terrain structure of the vegetable planting field, maximize the adaptability of the equipment to different terrains and the operation effect, effectively improve the tilling and weeding operation quality and efficiency of the vegetable planting field, reduce the operation omissions or damages to vegetable plants that may be caused by the mismatch between the equipment and the terrain, and ensure a healthy growth environment and good production benefits for vegetable planting.

[0048] In addition, referring to Figures 1 - 4 As shown, the tilling and weeding equipment for vegetable planting also includes a rake tooth weeding assembly 6, and the rake tooth weeding assembly 6 is used to rake the accumulated grass on the rake teeth 4 to one side in the direction perpendicular to the movement direction of the rake teeth 4.

[0049] Among them, referring to Figure 9As shown in the figure, the rake tooth weeding assembly 6 includes a convex plate 61 fixed to the connecting column 7 above the rake teeth 4. A first groove 611 along the length direction of the mounting base 8 is provided on the convex plate 61. A liftable rake claw 65 is provided in the first groove 611. A moving structure 62 is provided on the convex plate 61. The moving structure 62 is used to move the rake claw 65 back and forth along the length direction of the first groove 611. And the weeding direction of the rake claw 65 is perpendicular to the weeding direction of the rake teeth 4, and the rake claw 65 is located obliquely above the weeding direction of the rake teeth 4.

[0050] The moving structure 62 includes a second motor 621 installed at the end of the convex plate 61. The output end of the second motor 621 is installed with a second lead screw 622 extending into the first groove 611. A second lead screw nut seat 623 is installed outside the second lead screw 622. An installation block 63 is fixed outside the second lead screw nut seat 623. A telescopic rod 64 is installed through the installation block 63. The telescopic rod 64 is preferably an electric telescopic rod. The rake claw 65 is installed at the bottom end of the telescopic rod 64 through a mounting plate.

[0051] Through the above, after the equipment has carried out soil loosening and weeding operations for a period of time (preferably after the soil loosening and weeding of a row in the vegetable planting field are completed), a large amount of weeds often accumulate on the rake teeth 4 of the equipment. At this time, it is necessary to start the rake tooth weeding assembly 6. First, start the telescopic rod 64. The telescopic rod 64 pushes the connected rake claw 65 to gradually move downward until the rake claw 65 touches the weeds accumulated on the rake teeth 4. Subsequently, start the second motor 621. The output end of the second motor 621 drives the connected second lead screw 622 to rotate. The installation block 63 will move from one end to the other along the set track with the second lead screw nut seat 623. During this moving process, the rake claw 65 will gradually rake and gather the weeds accumulated on the rake teeth 4 to one side of the equipment. This cleaning method can efficiently solve the problem of weed accumulation on the rake teeth 4, ensure that the normal working performance of the rake teeth 4 is not affected, enable the equipment to always maintain a good working state during long-term operations, greatly improve the continuous operation ability and working efficiency of the equipment, and there is no need to manually remove the weeds accumulated on the rake teeth 4, providing a strong guarantee for the continuous and stable soil loosening and weeding operations in the vegetable planting field.

[0052] Embodiment 2: Please refer to Figure 5 As shown in the figure, this embodiment is an extension based on Embodiment 1: Guide blocks 56 are fixed on both sides of the connecting plate 51 and near the edges. A vertical guide rod 57 is connected to the vehicle frame 1. The guide rod 57 penetrates through the guide blocks 56.

[0053] Through the above, when the connecting plate 51 is lifted or lowered, the guide blocks 56 move along the vertical guide rod 57, which can improve the stability, prevent deviation, and provide a stable working platform for the associated working components, such as the soil loosening teeth 3 and the rake teeth 4, etc.
