Description

TECHNICAL FIELD

[0001] The utility model relates to the field of garden machinery, especially to a garden machinery walking wheel locking mechanism. BACKGROUND

[0002] The walking wheel of the rotary cultivator is an important component of the rotary cultivator, which supports the weight of the rotary cultivator, provides power transmission, controls the plowing depth, and improves the work efficiency. For depth control, the rotary cultivator can adjust the position and angle of the walking wheel on the rotary cultivator by adjusting the walking wheel locking mechanism, so that the blade assembly of the rotary cultivator acts on the ground at different angles and heights, thereby achieving the effect of adjusting the plowing depth.

[0003] The traditional walking wheel locking mechanism usually consists of a limiting block, a limiting pin, a handle cover, a reset spring, a fixing device, a bracket, and a walking wheel. The mechanism fixes the limiting block on the rotary cultivator body base through the fixing device. When the height needs to be adjusted, the limiting pin is pulled by the handle cover, so that the walking wheel is kept in a state of disengagement with the rotary cultivator body. At this time, the height and angle of the walking wheel can be adjusted. After completion, the handle cover is released, and the limiting pin is clamped back to the rotary cultivator body base by the reset spring, completing the adjustment step. This mechanism has a complex structure and is difficult to operate, sometimes even requiring multiple people to operate, and needs to be improved and upgraded. SUMMARY

[0026] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0027] A locking mechanism for the wheels of garden machinery, such as Figure 1 As shown, the device includes a mounting body 1, an adjusting disc 2, and a bracket 3. The mounting body 1 is a hand handle for agricultural machinery. The adjusting disc 2 is fixedly mounted on the mounting body 1. The top of the bracket 3 is rotatably connected to the mounting body 1. The traveling wheels 4 are mounted on the bottom of the bracket 3. The height and angle of the traveling wheels 4 can be adjusted by rotating the bracket 3. The adjusting disc 2 is fan-shaped and has multiple slots 5 on its arc-shaped outer periphery. The slots 5 are evenly spaced along its circumference to form multiple positions. In addition, an elastic limiting piece 6 is installed on the bracket 3. The elastic limiting piece 6 has a locking post 7 that engages with the slots 5. The engagement of the locking post 7 with the slots 5 achieves the rotation limit of the bracket 3. When the angle of the bracket 3 needs to be adjusted, simply operate the elastic limiting piece 6 to disengage the locking post 7 from the slots 5, and the bracket 3 can be rotated for adjustment.

[0028] The gear adjustment is achieved by engaging the locking post 7 on the elastic limit plate 6 with different locking slots 5 on the adjustment plate 2. This allows for adjustment of the height and angle of the traveling wheel 4 on the bracket 3. The structure is simple, and during operation, simply press the elastic limit plate 6 to disengage the locking post 7 from the locking slot 5, and then rotate the bracket 3 for adjustment. After releasing the elastic limit plate 6, the locking post 7 will re-engage into the locking slot 5 under the elastic reset action. The operation is simple and convenient, and can be quickly operated by a single person.

[0029] like Figure 2 and Figure 3 As shown, the bracket 3 has a recessed portion 8 on the side facing away from the adjustment disc 2. The recessed portion 8 can save the material cost of the bracket 3. The elastic limiting piece 6 is relatively thin and is installed in the recessed portion 8, so that the elastic limiting piece 6 will not protrude outward and occupy space, making the structure more compact.

[0030] like Figure 2 and Figure 3As shown, the adjusting disc 2 is fixed by the bolt 9 and the nut 10, the bolt 9 passes through the mounting body 1 and the adjusting disc 2, and the nut 10 is screwed on the end of the bolt 9 to achieve the mounting and fixing. The mounting holes for the bolt 9 are also provided on the bracket 3 and the elastic limiting sheet 6, that is, the bracket 3 and the elastic limiting sheet 6 are connected and mounted by the same bolt 9, effectively reducing the number of parts, making the mounting structure more simplified and compact, and synchronously achieving the simultaneous installation of multiple components during installation, improving the installation efficiency.

[0031] As shown in Figure 2 and Figure 3 , the clamping column 7 is stamped on the elastic limiting sheet 6, and the through hole 11 for the clamping column 7 to pass through is provided on the bracket 3. The hole diameter of the through hole 11 is larger than the outer diameter of the clamping column 7. In the present embodiment, the clamping column 7 is in the shape of a truncated cone, and the outer diameter of the clamping column 7 gradually increases from the top end to the bottom end. In actual use, the elastic limiting sheet 6 is deformed by applying force to it, causing the clamping column 7 to come out of the through hole 11 and thus disengage from the clamping groove 5, completing the angle adjustment of the bracket 3. After that, the elastic limiting sheet 6 is loosened, and under the action of the elastic restoring force, the clamping column 7 reenters the clamping groove 5 through the through hole 11 to achieve clamping. The operation is simple and convenient. The special design of the through hole 11 and the clamping column 7 effectively avoids the phenomenon of jamming interference during use, ensuring that the clamping column 7 can be easily disengaged from and clamped into the clamping groove 5.

[0032] As shown in Figure 2 and Figure 3 , the bottom end of the elastic limiting sheet 6 has a bent and horizontal bent portion 12, and the bent portion 12 has a through slot 13 for the bracket 3 to pass through. The opening area of the through slot 13 is larger than the cross-sectional area of the bracket 3, that is, the bracket 3 has enough space to move in the through slot 13 during the deformation of the elastic limiting sheet 6, avoiding interference. The end of the bent portion 12 has a downward operation end 14, which is a downward flange. The design of the operation end 14 facilitates people to hold the operation end 14 to apply force to the elastic limiting sheet 6, making the operation and force application more convenient. In addition, the width of the bent portion 12 is greater than the width of the elastic limiting sheet 6, so that the width of the bent portion 12 and the operation end 14 is larger, having better structural strength and being more convenient to hold.

[0033] As shown in Figure 2 and Figure 3 , the elastic limiting sheet 6 has a groove on one side and a convex portion 15 on the other side. The groove and the convex portion 15 can be formed on the elastic limiting sheet 6 by stamping during processing. The design of the groove and the convex portion 15 can improve the overall structural strength of the elastic limiting sheet 6, improve the durability and service life of the elastic limiting sheet 6, and reduce the phenomenon of breaking during deformation.

[0034] As shown in Figure 2 and Figure 3 Figure 2 Figure 3As shown, each corner of the card slot 5 has a rounding 16, the rounding 16 is designed to make the inner wall of the card slot 5 arc, which is more convenient for the cooperation of the card slot 5 and the card column 7, and can also reduce the interference and stagnation phenomenon of the cooperation of the card column 7 and the card slot 5, and the card column 7 and the card slot 5 are more smooth in the card-in and card-out.

[0035] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
