[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a tillage and weeding tool for grain planting, including a shell component 1, a slide bar 2 is arranged inside the shell component 1, slide blocks 3 are arranged on the top of both sides of the slide bar 2, a plurality of slots 4 are opened on one side of the slide bar 2, a fixing seat 5 is arranged at the bottom end of the slide bar 2, two mounting plates 6 are arranged on one side of the fixing seat 5, a connecting shaft 7 is arranged between the two mounting plates 6, a hoe 8 is arranged on the outside of the connecting shaft 7 through a bearing, positioning grooves 9 are opened on both sides of the hoe 8, a threaded knob 10 is arranged on one side of the two mounting plates 6 through a bearing, a moving block 11 is arranged on the outside of the two threaded knobs 10, and positioning rods 12 are arranged at both ends of one side of the two moving blocks 11.

[0023] In this embodiment, Figure 1 As shown, the housing assembly 1 includes a sleeve 101 , two inner walls of the sleeve 101 are provided with sliding grooves 102 , and a control rod 103 is provided on one side of the sleeve 101 .

[0024] In this embodiment, Figure 1 As shown, the control rod 103 and the sleeve 101 are threadedly connected to fix the slide bar 2, thereby preventing the slide bar 2 from slipping into the sleeve 101 due to loosening during use, thereby greatly improving the stability of the slide bar 2 during use.

[0025] In this embodiment, Figure 2As shown, the slide groove 102 and the slider 3 are set to be in sliding connection, which increases the stability of the slide bar 2 during movement, thereby preventing the slide bar 2 from tilting or deflecting during movement.

[0026] In this embodiment, Figure 2 As shown, the outer dimensions of the slide bar 2 are consistent with the inner dimensions of the sleeve 101, so that the length of the hoe handle can be adjusted according to the needs of the user, thereby greatly improving the user experience during use, thereby meeting the needs of inter-row weeding tools for grain cultivation.

[0027] In this embodiment, Figure 3 As shown, the hoe 8 rotates with the central axis of the connecting shaft 7 as the center of the circle; the hoe 8 can be folded and stored, which solves the problem that the hoe 8 cannot be folded and stored and occupies a large amount of space, thereby greatly improving the convenience of the tillage and weeding equipment used for grain planting, and making it easier for people to carry.

[0028] In this embodiment, Figure 4 As shown, a snap-fit ​​structure is provided between the positioning rod 12 and the positioning groove 9, so as to fix the hoe 8 and prevent the hoe 8 from bending during folding and storage or during use, thereby increasing the stability of the hoe 8 during storage or use.

[0029] The use method and advantages of the utility model: When the intertillage weeding device for grain planting is used, the working process is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, when the tillage and weeding tool is needed, the slide bar 2 is pulled, so that the slide bar 2 drives the hoe 8 to move out of the sleeve 101 under the cooperation of the slider 3 and the slide slot 102, so that the slide bar 2 drives the hoe 8 to adjust to the required length, and then the control rod 103 is rotated to make the control rod 103 engage with the inside of the card slot 4 to form a card connection structure, so that the length of the hoe handle can be adjusted according to the needs of the user, thereby greatly improving the user's experience during use. When the tillage and weeding tool is used and the hoe 8 needs to be folded and stored, the hoe 8 is moved to make the hoe 8 8 is rotated to a vertical state with the central axis of the connecting shaft 7, and then the two threaded knobs 10 are rotated. At this time, the threaded knob 10 drives the two positioning rods 12 to move under the limit of the through hole through the moving block 11. At this time, the positioning rods 12 are engaged with the inside of the positioning groove 9 to form a clamping structure, so that the hoe 8 can be folded and stored, which solves the problem that the hoe 8 cannot be folded and stored and occupies a large amount of space, thereby greatly improving the convenience of the inter-tillage and weeding equipment for grain planting, making it easy for people to carry, and thus meeting the needs of inter-tillage and weeding equipment for grain planting.
