Problems solved by technology

like figure 1 and 2 As shown, the existing protective structure is to set a fence-type cover structure formed by a plurality of connecting bars I03 outside the blade assembly 02 at the bottom of the trimmer casing 01, and the connecting bar I03 passes through the connecting bar II04 at the top. The unavoidable problems of this protective structure are: 1. The resistance of the trimmer is relatively large when it is working, and the automatic trimmer needs to provide greater power; 2. The protection range of the fence-type cover structure is limited, and the operator or When children are playing, their arms, arms, fingers, etc. can easily extend into the fence-type cover from the gap between the casing 01 and the ground and be cut by the blades. The structure of the fence-type cover has a relatively large safety hazard; 3. The fence-type cover structure, due to the long length of the connecting strip, is suspended in the middle and is only fixed at both ends. When mowing grass, due to the large resistance or when the cover touches the ground, the connecting strip is easy to break; 4. The fence-type cover The structure is installed on the casing 01 by fasteners such as bolts, which is time-consuming and labor-intensive, and the labor cost is high

Embodiment 1

[0025] Such as image 3 with 4 Shown is an embodiment of a lawnmower protection device, in which the lawnmower has a casing 1 and a cutter head 21 mounted on the casing 1 and exposed to the bottom surface of the casing 1, and the cutter head 21 is provided below Cutter head 22. Three uniformly arranged blades 23 are installed on the edge of the cutter head 22. A drive motor is installed on the cutter head frame 21. The output end of the drive motor is connected to the cutter head 22 and drives the cutter head to rotate. The lawn mower protection device includes A number of long thin ribs 3 arranged on the bottom surface of the casing 1 and a number of protective columns 4 arranged on the bottom surface of the cutter head holder 21; the length direction of the ribs 3 is consistent with the extension direction of the bottom surface of the casing 1, and the width direction is approximately perpendicular to the machine On the bottom surface of the shell 1, ribs 3 surround the cutter...

Embodiment 2

[0027] Such as Figure 3 to 5 Shown is an embodiment of a lawn mower. The lawn mower has a casing 1 and a cutter frame 21 mounted on the casing 1 and exposed below the bottom surface of the casing 1. The bottom surface of the casing 1 has a circular groove 11 , The center of the circular groove 11 has a hole 12, and the top of the cutter head holder 21 has a cylinder 212. The cutter head holder 21 is arranged in the circular groove 11, and the cylinder 212 extends into the hole 12 to slidably fit with the casing 1. The outer wall of the barrel 212 is provided with a slider 213, and the inner wall of the hole 12 is provided with a sliding groove 121 that is slidably engaged with the slider 213, so that the cutter head 21 can slide up and down relative to the casing 1, and a motor is installed in the cylinder 212. A cutter head 22 is installed at the output end of the motor. Three evenly distributed blades 23 are installed on the edge of the cutter head 22. Both the cutter head 2...

Embodiment 3

[0029] Such as Image 6 with 7 As shown, the difference from the first embodiment is that part or all of the ribs 3 on the bottom surface of the casing 1 are replaced by a number of protective columns 4 arranged in rows, and the arrangement direction of each row of protective columns 4 is the same as that of the mower. The direction of travel during work is the same, and there is a certain distance between two adjacent rows of protective columns 4.

Abstract

The invention provides a mower protection device and a mower. The mower comprises a machine casing and a blade assembly. The blade assembly is arranged under the bottom face of the machine casing. The mower protection device comprises a plurality of protection pieces protruding on the bottom face of the machine casing. The protection pieces are arranged on the periphery of the blade assembly, and a distance is formed between every two connected protection pieces. Due to the fact that the protection pieces are arranged on the bottom face of the machine casing of the mower on the periphery of the blade assembly, the problem that a gap between the bottom face of the machine casing of the mower and the ground is large is solved, ribs achieve a guide effect on hay when the mower conducts hay mowing, and driving resistance can be greatly reduced.

Description

Technical field [0001] The invention relates to a protective device and a lawn mower for a lawn trimmer, in particular for a rotating blade cutter of an automatic, self-guided and self-supporting lawn trimmer. Background technique [0002] In an automatic lawn trimmer, a traditional rotary lawn trimmer in which a motor-driven blade rotates around a substantially vertical axis requires a protective structure around the blade to prevent injury to the user or other people approaching the trimmer during operation . Such as figure 1 with 2 As shown, the existing protective structures are all set at the bottom of the trimmer housing 01 and cover the blade assembly 02 outside the fence type cover structure formed by several connecting bars I03, the connecting bar I03 passes through the connecting bar II04 at the top. Connection, the inevitable problems of this protective structure are: 1. The pruning machine has a large resistance when it is working, and it needs to provide more power ...
