Description

Technical Field

[0001] The present application relates to the technical field of lawn mowers, and in particular to a lawn mower cutter head structure. Background Art

[0002] A lawn mower, also known as a lawn machine, consists of a cutter disc, an engine, running wheels, a walking mechanism, a blade, an armrest and a control part. Its efficiency is 8 to 10 times higher than manual weeding, which saves the working time of weeding workers and reduces a lot of human resources.

[0003] However, the existing lawn mower cutter head is not easy to replace. When the lawn mower is used frequently, the cutter head is most likely to be damaged. The damage of the cutter head causes the entire device to be abandoned and unused, thereby increasing the cost. Therefore, a lawn mower cutter head structure is needed to improve the above problem. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present application provides a lawn mower cutter head structure that is easy to disassemble and assemble by replacing the cutter head through a cutter head replacement mechanism, thereby avoiding the entire device being discarded due to damage to the cutter head, reducing costs, and having a high degree of practicality.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a lawn mower cutter head structure, comprising a mounting plate, wherein the mounting plate is moved by a moving mechanism, a motor is fixedly mounted on the mounting plate, a rotating plate is fixedly mounted on the output end of the motor, the rotating plate is limited by a limiting mechanism, an electric cylinder is arranged on the rotating plate, a first fixed plate is fixedly mounted on the electric cylinder, a cutter head replacement mechanism is arranged on the first fixed plate, the cutter head replacement mechanism comprises a second fixed plate, a cutter head is arranged on the second fixed plate, two third fixed plates are symmetrically fixedly mounted on the first fixed plate, two telescopic columns are fixedly mounted on the two third fixed plates, two telescopic columns on the same side are connected by a clamping block, a spring is mounted on each telescopic column, and two ends of each spring are respectively fixedly connected to the corresponding third fixed plate and the clamping block, two connecting plates are symmetrically fixedly mounted on the second fixed plate, both connecting plates are provided with a clamping slot, two clamping blocks are clamped with the two clamping slots, two sliding holes are symmetrically arranged on the second fixed plate, the two connecting plates are slidably connected with the two sliding holes, one end of the two connecting plates and the two clamping blocks are arranged as an arc mechanism, and one of the clamping blocks and one of the connecting plates are connected by two first bolts.

[0008] Preferably, the moving mechanism comprises four legs, which are symmetrically fixedly mounted on the bottom end of the mounting plate, and a moving wheel is provided at the bottom end of each leg.

[0009] Furthermore, the limiting mechanism includes two limiting rods, which are symmetrically fixed on the top ends of the two rotating plates. An annular slide rail is provided at the bottom end of the mounting plate, and the two limiting rods are slidably connected to the slide rails respectively.

[0010] Furthermore, the first fixing plate and the second fixing plate are connected by two second bolts.

[0011] Based on the above solution, auxiliary plates are provided on the two card blocks.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the present application provides a lawn mower cutter head structure, which has the following beneficial effects:

[0014] The mower head structure moves the mounting plate to the working area through a moving mechanism, and slides the two connecting plates to the two sliding holes. The arc-shaped design of the two connecting plates and the two clamping blocks enables the two connecting plates to squeeze and move the two clamping blocks when the two connecting plates are in contact with the two clamping blocks. The two clamping blocks are driven to move through the cooperation of multiple telescopic columns and multiple springs. When the two clamping blocks are parallel to the two clamping grooves, the two clamping blocks are clamped in the two clamping grooves, thereby completing the position limiting operation of the two connecting plates. The two clamping blocks and the two connecting plates are connected by rotating multiple first bolts. The installation of the cutter head is completed by starting the motor, which provides power to drive the rotating plate to rotate, and the rotating plate is limited by the limiting mechanism. When the rotating plate rotates, it drives the electric cylinder, the first fixed plate and the cutter head to rotate synchronously, and the cutter head is used to mow the grass. When the cutter head needs to be replaced, the connection between the two connecting plates and the two clamping blocks by the multiple first bolts is released, so that the two clamping blocks are kept away from the two connecting plates, so that the cutter head can be replaced. The disassembly and assembly are convenient, and the waste of the entire device due to damage to the cutter head is avoided, the cost is reduced, and the practicability is high.
