Abstract

The utility model discloses a grass beating head, which comprises a sheet I and a sheet II, wherein the contact surfaces of the sheet I and the sheet II are matched with each other, so that a stringing groove and a grass beating rope fixing groove are formed; installation holes are formed in the middles of the sheets; and a nut is used for connecting the grass beating head to an output shaft of a grass beating machine through the installation holes. The grass beating head is characterized in that: the stringing groove is connected with the grass beating rope fixing groove; a spring is arranged in the grass beating rope fixing groove; one end of the spring which is close to the stringing groove is connected with a ratchet wheel; the teeth of the ratchet wheel face away from the stinging groove; the contact surfaces of the sheet I and the sheet II further comprise rope outlet holes; and the rope outlet holes are connected with the stringing groove. The grass beating head has the advantages: a grass beating rope is convenient and rapid for replace, the grass beating head is suitable for grass beating ropes of any section shape including circular grass beating ropes, triangular grass beating ropes and the like; and a sheet alloy material is hard and durable.

Description

Moving head

Technical field

The utility model belongs to graden machine component technology field, refers in particular to a kind of simple and easy moving head.

Background technology

Along with people's constantly strengthens with requirement the consciousness of vegetation ecological and city trees and shrubs; Mower is as portable graden machine; Use more and more widely; Moving head is even more important as the consumption of mower and the cutter sweep of mower, and its structure directly affects operator's labour intensity and work quality.

The utility model content

The purpose of the utility model provides a kind of firm in structure, easy to operate moving head.

The utility model has adopted following technical scheme:

Moving head comprises thin slice I, thin slice II, thin slice I and thin slice II contact-making surface cooperatively interact constitute the wire rope handling groove, beat the grass rope holddown groove and rope hole; Thin slice central authorities are provided with installing hole, and nut is connected to moving head on the output shaft of mower through installing hole, it is characterized in that; The wire rope handling groove joins with the rope holddown groove of beating the grass; The rope of beating the grass is provided with spring in the holddown groove, and spring is connected with ratchet at nearly wire rope handling groove one end, and the back of tooth of ratchet is to the wire rope handling groove; Rope hole and wire rope handling groove join.

Beat the grass when rope in installation, penetrate from the wire rope handling groove rope of will beating the grass, beating the grass rope is run into ratchet, because the back of tooth of ratchet is to the wire rope handling groove, ratchet is extruded and compresses spring, and the rope section of beating the grass passes ratchet and gets into rope hole; Under the effect of ratchet, the motion of the rope of beating the grass is unidirectional, can only be from the wire rope handling groove to rope hole.

Beat the grass when rope in replacing, extract, and reinstall the new rope of beating the grass and get final product from the rope hole rope of will beating the grass.

Preferably, said thin slice I and thin slice II contact-making surface comprise that 2 groups is the centrosymmetric wire rope handling groove and the rope holddown groove of beating the grass with installing hole.

Preferably, said wire rope handling groove is a circular arc.

Preferably, said thin slice I and thin slice II adopt alloy.

Preferably, the moving head outside is provided with the dust cap that nut is covered.

Preferably, said moving head comprises between thin slice I, the thin slice II being provided with thin slice III, thin slice I and thin slice III and thin slice II and thin slice III contact-making surface cooperatively interact constitute the wire rope handling groove, beat the grass rope holddown groove and rope hole.

The advantage of the utility model is: it is convenient and swift to change the rope of beating the grass, and is suitable for the rope of beating the grass of any cross sectional shape, can be circular, triangle etc.; The foil alloys material, sturdy and durable.
