Description

Technical Field

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

[0002] After planting vegetables, as the growth and development of vegetables gradually advances, weeds will inevitably grow in the vegetable planting area. The growth and spread of these weeds will have many adverse effects on the growth of vegetables. Therefore, it is often necessary to use loosening and weeding equipment to loosen the soil in the vegetable planting area and clean up the weeds in the field at the same time.

[0003] At present, in addition to the traditional time-consuming and labor-intensive hoes, some hand-held semi-automatic soil loosening and weeding equipment are often used to carry out soil loosening and weeding operations in vegetable fields. However, vegetable planting fields show significant diversity in terrain structure. Among them, some vegetable planting fields adopt a pattern of alternating distribution of ditches and ridges. This layout method 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. It has unique advantages for the cultivation of specific types of vegetables. Other vegetable planting fields adopt an overall flat pattern. This terrain is convenient for large-scale mechanized operations and unified planting management. Most of the existing soil loosening and weeding equipment is based on relatively flat terrain conditions. The structure and function of the equipment exposed difficult-to-overcome limitations when facing the vegetable planting fields with alternating furrows and ridges. For example, the working parts of the equipment have a relatively limited adjustment range in height and angle. When applied to the ridge, it may not be able to accurately fit the inclination of the furrow surface and the ridge surface at the same time to perform effective soil loosening and weeding operations, resulting in incomplete weeding or unnecessary damage to the ridge. These problems not only greatly reduce the working efficiency of the existing soil loosening and weeding equipment in the vegetable planting fields with alternating furrows and ridges, but also may have a negative impact on the growth environment of vegetables due to poor operating results, such as damaging the root system of vegetables and leaving a large number of weeds. For this reason, we propose a soil loosening and weeding equipment for vegetable planting. Summary of the invention

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 1-Figure 9 As shown, the present invention provides a technical solution: a soil loosening and weeding equipment for vegetable planting, comprising a frame 1, the frame 1 serves as the basic structure of the entire equipment and plays a role of stable support, a driving wheel 2 is installed at the bottom end of the frame 1, the driving wheel 2 can provide power for the movement of the equipment, so that it can move flexibly in the vegetable planting field, and a handrail is connected to one side of the frame 1, the design of the handrail is convenient for the staff to grasp and apply force during the operation, so as to better control the running direction of the equipment, in addition, a switch can be installed on the handrail, the position of the switch is convenient for the staff to easily reach and operate when operating the equipment, so as to accurately control the start, stop and switching of various functions of the equipment, which greatly improves the convenience and work efficiency of the staff, makes the whole equipment more handy in actual use, and can efficiently complete the soil loosening and weeding tasks.

[0040] In addition, the soil loosening and weeding equipment for vegetable planting also includes a lifting component 5, a mounting seat 8 and a deformation component 9. There are two mounting seats 8, which are arranged front and back, and the bottom ends of the two mounting seats 8 are respectively installed with loosening teeth 3 and rake teeth 4, and the rake teeth 4 are arranged on the rear side of the loosening teeth 3 to achieve loosening the soil before weeding, and each mounting seat 8 includes a fixed seat 81 and two movable seats 82, and the two movable seats 82 are hinged at both ends of the fixed seat 81. The lifting component 5 is installed on the frame 1, and a connecting column 7 is connected between the lifting component 5 and the mounting seat 8. The lifting component 5 is used to achieve synchronous lifting of the two mounting seats 8 to adjust the depth of the loosening teeth 3 and the rake teeth 4 into the soil layer. The deformation component 9 is arranged on the mounting seat 8, and the deformation component 9 is used to achieve 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 loosening and weeding of the ditch and ridge parts of different vegetable planting sites.

[0041] Among them, see Figure 5As shown, 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 forward and reverse motor. Two first lead screws 53 are provided. The two first lead screws 53 vertically penetrate the frame 1 through bearings. The first motor 52 is installed on the 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 on the outside of 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 55.

[0042] The linkage member 55 includes pulleys 551 respectively fixed to the outside of the two first lead screws 53, and a belt 552 is arranged between the two pulleys 551. When the first motor 52 is started, its output end starts to run and drives the first lead screw 53 connected thereto to rotate. At the same time, with the help of the transmission connection constructed by the belt 552, the power can be transmitted to the first lead screw 53 with the pulley 551 installed on the other side, thereby ensuring that the first lead screws 53 on both sides rotate synchronously. In the process of synchronous rotation of the first lead screw 53, the first lead screw nut seats 54 on both sides will rotate due to the effect of the thread. The loosening teeth 3 and the rake teeth 4 perform synchronous lifting and lowering movements along the axial direction of the screw, and the loosening teeth 3 and the rake teeth 4 are respectively firmly connected and installed with the corresponding first screw nut seats 54. In this way, with the synchronous lifting and lowering of the first screw nut seat 54, the loosening teeth 3 and the rake teeth 4 can also accurately realize synchronous lifting and lowering movements. Through this ingenious mechanical transmission design, not only can the lifting and lowering control of the loosening teeth 3 and the rake teeth 4 be efficiently realized, but also the stability and coordination of the entire device during operation are guaranteed, providing a reliable and accurate action execution basis for subsequent operations such as loosening soil and raking grass in vegetable planting fields.

[0043] See also Figure 6-Figure 8 As shown, the deformation component 9 includes a third motor 91 installed on the outer wall of the fixed seat 81, the third motor 91 is a forward and reverse motor, the fixed seat 81 is hollow inside, and recessed grooves are 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, and a rotatable third connecting rod 96 is installed inside the fixed seat 81 and beside the second connecting rod 95, and the two movable seats 82 are both provided with a second groove 92 at one end facing the fixed seat 81, and the second groove A first connecting rod 93 is fixed inside the groove 92, and sprockets 94 are fixed outside the first connecting rod 93, the second connecting rod 95 and the third connecting rod 96. Chains 97 are respectively connected between the sprockets 94 on the two first connecting rods 93 and the adjacent sprockets 94, 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 achieve simultaneous opposite deflection of the second connecting rod 95 and the third connecting rod 96, so that the movable seats 82 on both sides can be deflected upward or downward synchronously.

[0044] The gear connector 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 meshedly 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 to loosen the soil and weed. Before performing the loosening and weeding operation, when facing the weeding task of the vegetable planting field where the ditch and the ridge are alternately distributed, 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 thereon also starts to rotate, which will drive the connected chain 97 to start a cycle. Under the pulling action of the chain 97, the movable seat 82 on one side will be pulled upward to start Deflect upward. At the same time, during the rotation of the second connecting rod 95, the first gear 981 installed thereon also rotates synchronously. Because the first gear 981 and the second gear 982 are meshed with each other, the rotation of the second gear 982 will drive the third connecting rod 96 and the sprocket 94 thereon to rotate together. Similarly, the sprocket 94 will also apply an upward pulling force to the movable seat 82 on the other side through the chain 97 connected thereto, causing it to deflect upward synchronously. Through such a transmission system, the inclination angles of the movable seats 82 on both sides can be adapted to the inclined surface of the ridge portion, thereby laying a solid foundation for the subsequent efficient and precise soil loosening and weeding operations on the inclined surface of the ridge portion.

[0046] For a vegetable planting field where there is no alternating distribution of grooves and ridges, the movable seat 82 and the fixed seat 81 are placed in a straight line, and the movable seat 82 does not need to perform a complicated deflection operation to adapt to a specific slope.

[0047] In summary, this deformable design can fully take into account the special terrain structure of the vegetable planting area, maximize the adaptability and operation effect of the equipment to different terrains, effectively improve the quality and efficiency of soil loosening and weeding operations in the vegetable planting area, reduce the omissions of operations or damage to vegetable plants caused by the mismatch between equipment and terrain, and ensure a healthy growth environment and good production benefits for vegetable planting.

[0048] Also, see Figure 1-Figure 4 As shown, the soil loosening and weeding equipment for vegetable planting also includes a rake tooth weeding assembly 6, which is used to rake the accumulated grass on the rake teeth 4 to one side in a direction perpendicular to the movement direction of the rake teeth 4.

[0049] Among them, see Fig. 9As shown, the rake tooth weeding assembly 6 includes a convex plate 61 fixed on the connecting column 7 above the rake teeth 4, and a first groove 611 is opened on the convex plate 61 along the length direction of the mounting seat 8, and a liftable rake claw 65 is arranged in the first groove 611. A movable structure 62 is provided on the convex plate 61, and the movable structure 62 is used to realize the rake claw 65 to move back and forth along the length direction of the first groove 611, and the raking direction of the rake claw 65 is perpendicular to the raking direction of the rake teeth 4, and the rake claw 65 is located obliquely above the raking direction of the rake teeth 4.

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

[0051] Through the above, after the device has been performing a period of soil loosening and weeding operations (preferably after a row of soil loosening and weeding is completed in a vegetable planting area), a large amount of weeds will often accumulate on the rake teeth 4 of the device. At this time, it is necessary to start the rake tooth weeding assembly 6, first start the telescopic rod 64, and the telescopic rod 64 pushes the rake claw 65 connected thereto to gradually move downward until the rake claw 65 contacts the weeds accumulated on the rake teeth 4, then start the second motor 621, and the output end of the second motor 621 drives the second lead screw 622 connected thereto to rotate, and the mounting block 63 will rotate along with the second lead screw nut seat 623 It moves from one end to the other end along the set track. During this movement, the rake claws 65 will gradually rake and send the weeds accumulated on the rake teeth 4 and gather them to one side of the equipment. This cleaning method can effectively 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, and enable the equipment to always maintain a good working state during a long period of operation, greatly improving the continuous operation capacity and work efficiency of the equipment. There is no need to manually remove the weeds accumulated on the rake teeth 4, which provides a strong guarantee for the continuous and stable loosening and weeding operations in the vegetable planting field.

[0052] Example 2: Please refer to Figure 5 As shown, this embodiment is an extension of the embodiment 1: guide blocks 56 are fixed on both sides of the connecting plate 51 and close to the edges, and a vertical guide rod 57 is connected to the frame 1, and the guide rod 57 passes through the guide block 56.

[0053] Through the above, when the connecting plate 51 is raised or lowered, the guide block 56 moves along the vertical guide rod 57, which can improve stability and prevent deviation, thereby providing a stable working platform for the associated working parts, such as the loosening teeth 3 and the rake teeth 4.
