Description

Grass trimmer with adjustable grass trimming head height

Technical Field

The utility model belongs to the technical field of the machine of beating the grass, refer in particular to a machine of beating the grass of adjustable grass head height.

Background

The grass trimmer is an agricultural mechanical device which is widely applied to cutting various crops such as green (dry) corn stalks, rice straws and the like and pasture. At present, the grass mowing ropes of the grass mowing machines of the same type are almost connected by winding and tying the grass mowing ropes on the circular rings at the two sides of the grass mowing head, the connection mode is time-consuming and labor-consuming in operation, and complicated in operation when the grass mowing ropes need to be replaced every time, so that the production efficiency is low, and the satisfaction degree of users is low when the grass mowing machines are used; on the other hand, the working height of the grass trimmer of the same type after winding the grass cutting rope is only fixed by one height, so that the height of the lawn after grass cutting is always fixed, and the lawn cannot be adjusted according to requirements, so that the application range of the grass trimmer is limited.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a stable in structure, can adjust the machine of beating grass of the adjustable height of beating the grass head of beating the grass.

The purpose of the utility model is realized like this: the utility model provides an adjustable machine of beating grass of first height, includes the machine main part of beating grass, it is equipped with the first assembly of beating grass to beat grass quick-witted main part front end, the first assembly of beating grass is including beating grass head and end cover, beat the overhead spacing hole of having seted up of grass, wear to be equipped with the axis of rotation in the spacing hole, the end cover sets up the lower extreme at the axis of rotation, spacing hole both sides all are equipped with the keyway, be equipped with the fastener in the keyway, fastener one side and the first spiro union of beating grass, the spacing slide rail looks butt of seting up in opposite side and the axis of rotation, elasticity through the fastener realizes the regulation of the first height of.

Preferably, a sealing seat for preventing weeds from entering the machine is arranged above the grass cutting head.

Preferably, the grass cutting head is provided with fixing seats on both sides, and grass cutting blades are mounted on the fixing seats.

Preferably, one side of the grass mowing head assembly is provided with a baffle plate for preventing weeds from splashing.

Compared with the prior art, the utility model outstanding and profitable technological effect is: the utility model discloses a machine of beating grass can be through the height of manual regulation machine of beating grass, convenient and fast, and low in production cost has improved the practicality of machine of beating grass greatly.

Drawings

FIG. 1 is a schematic view of the present invention;

fig. 2 is a schematic structural diagram of the grass mowing head assembly of the utility model.

Detailed Description

The invention will be further described with reference to specific embodiments.

As shown in fig. 1-2, a grass trimmer with adjustable grass-mowing head 3 height comprises a grass trimmer main body 1, wherein a grass-mowing head assembly 2 is arranged at the front end of the grass trimmer main body 1, the grass-mowing head assembly 2 comprises a grass-mowing head 3 and an end cover 4, a limiting hole 5 is formed in the grass-mowing head 3, a rotating shaft 6 penetrates through the limiting hole 5, the end cover 4 is arranged at the lower end of the rotating shaft 6, key grooves 7 are formed in two sides of the limiting hole 5, fastening pieces 8 are arranged in the key grooves 7, one sides of the fastening pieces 8 are in threaded connection with the grass-mowing head 3, the other sides of the fastening pieces are in butt connection with limiting sliding rails 9 formed in the rotating shaft 6, and the height of the grass-mowing head 3 is adjusted through tightness of.

Whether this technical scheme's grass mowing head 3 can be through adjusting fastener 8 and axis of rotation 3 looks butt, adjust or fix grass mowing head 3's height, fastener 8 slides in spacing slide rail 9 because spacing slide rail 9's bottom surface is flat, so can make the better fastening of fastener 8 in spacing slide rail 9, after the user has adjusted the height, locking fastener 8 realizes the adjustment of height, whole process only needs adjustment fastener 8, and is convenient and fast, can make grass mowing machine's practicality better. The fastener 8 is a fastening screw.

Preferably, a sealing seat 10 for preventing weeds from entering the machine is arranged above the grass-mowing head 3. Inside the protection machine that can be better, prevent dust and weeds entering, increase the life of machine of beating the grass.

Preferably, fixing seats 11 are arranged on two sides of the grass cutting head 3, and grass cutting blades 12 are mounted on the fixing seats 11. Can conveniently change the grass cutting blade 12, the whole process is more rapid and practical.

Preferably, a baffle 13 for preventing weeds from splashing is arranged on one side of the grass mowing head assembly 2. Prevent the weeds from splashing and injuring people on the side in the operation process of the grass trimmer, and reduce the occurrence of dangerous accidents.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
