A head body is provided with an elastic valve, a claw teeth is arranged on the head body, the claw teeth is arranged on the outside of the elastic valve of the head body, the claw teeth is arranged on a teeth pin which is arranged on the head body, the claw teeth and the elastic valve are connected as integration, the claw teeth is a barb type, the claw teeth is rigid or elastic, and a blade tip or a flap head of the elastic valve is a claw teeth. The utility model has the advantages of simple structure, small size, light weight, convenient operation, low cost, etc. The utility model not only can be suitable for picking various classes of cotton in an ordinary planting condition but also can increase the picking net rate, and the cotton picking efficiency and the cotton quality can be increased.

Description

Efficient cotton picking-up head

The utility model relates to the device of gathering in the crops cotton, is a kind of efficient cotton picking-up head.

Existing cotton recovering device generally is divided into two kinds: a kind of is mechanical (twine cotton and realize plucking by spinning the rotation of splitting), its complex structure, cost height; Another kind be air-sucking type (by air-flow suction with cotton inhale from and realize plucking), though its structure is simpler, the cotton of results is had relatively high expectations, and adaptability is relatively poor; And above-mentioned two kinds of pickers all to exist the cotton of gathering impure higher, generally also the kind of cotton is implanted with strict requirement, and the cotton loss is bigger when gathering, but also reduces the grade of cotton easily.

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and designs the higher efficient cotton picking-up head of a kind of results efficient simple in structure, that adaptability is stronger.

The purpose of this utility model realizes by following measure: flexible valve on the body of this efficient cotton picking-up head; On a body, blade tooth is arranged; Blade tooth is installed in outside the elastic valve on the body; Blade tooth is installed on the alligator on the body; Blade tooth and elastic valve are one; Blade tooth is the hangnail formula; Blade tooth is rigidity or flexible; The blade tip of elastic valve or lobe head are blade tooth; Elastic valve be louvered or eclipsed form.

Accompanying drawing 1 is looked cutaway view for the master under the utility model most preferred embodiment preparation state;

Accompanying drawing 2 is the vertical view of accompanying drawing 1;

Accompanying drawing 3 is the utility model most preferred embodiment sucking cotton picking process fundamental diagram;

Accompanying drawing 4 is adopted cotton SBR fundamental diagram for the utility model most preferred embodiment blade tooth;

Accompanying drawing 5 is adopted cotton process fundamental diagram for the utility model most preferred embodiment blade tooth;

Accompanying drawing 6 is inhaled into the process fundamental diagram for the cotton on the utility model most preferred embodiment blade tooth;

Coding in the accompanying drawing is respectively: 1 is a body, and 2 is alligator, and 3 is blade tooth, and 4 is elastic valve, and 5 is cotton, and 6 is boll hull.

Below in conjunction with most preferred embodiment the utility model is further described:

Shown in attached Fig. 1 and 2, flexible valve 4 on the body 1 of this most preferred embodiment can be eclipsed form, as shown in Figure 2, is preferably louvered; Because this efficient cotton picking-up head has adopted elastic valve 4, when plucking beginning, elastic valve 4 is closed, and make and form high relatively negative pressure in this effect cotton picking-up head, and along with the increase of negative pressure, elastic valve 4 is local gradually to be opened, thereby form higher suction airstream suction cotton, and when cotton is inhaled into, can open and close with the size that sucks cotton again, form relative closure, thereby guarantee enough attractions cotton;

In order further to increase the effect of cotton picking, body 1 is provided with blade tooth 3, wherein, blade tooth can be an one with elastic valve, and blade tooth can be the hangnail formula, blade tooth can be rigidity or flexible, also can be with the blade tip of elastic valve or lobe head as blade tooth, as shown in Figure 2, blade tooth 3 preferably is installed in outside the elastic valve 4 on the body 1, and preferably be installed on the alligator 2 on the body 1, and blade tooth 3 can rotate around alligator 2; In the suction process of cotton,, because the comb of blade tooth 3 or elastic valve 4 scrapes, make impurity such as cauline leaf on the cotton, boll hull separated, thereby improved gather efficient and quality simultaneously because the effect of blade tooth 3 is plucked the easier quilt of cotton.

During use: at first this efficient cotton picking-up head is installed on the air draught road of cotton picker, this efficient cotton picking-up head is in the preparation state when not near cotton, and shown in attached Fig. 1 and 2, no air draught enters in the cotton picker air draught road at this moment; When this efficient cotton picking-up head front end during near cotton, supply with the negative pressure of certain suction by cotton picker air draught road, act on the elastic valve 4, and it is inwardly opened, form the inlet scoop of certain aperture, because the effect of negative pressure produces certain high velocity air this moment in the inlet scoop, thereby make cotton suck this efficient cotton picking-up head, at this moment blade tooth is also along with the rotating certain angle in this efficient cotton picking-up head that enters of cotton;

In cotton sucks the process of this efficient cotton picking-up head, have two kinds of situations to be described below respectively:

First kind of situation, as shown in Figure 3, when cotton 5 and boll hull 6 adhesions were little, cotton 5 was directly sucked in the picking head, after cotton picker air draught road is sent in the cotton picker by wind; The harvesting process is directly finished in circulation and so forth.

Second kind of situation, as shown in Figure 4, big or when cotton 5 and boll hull 6 adhesions because of other reason, cause and attract wind to fail cotton 5 and boll hull 6 are broken away from, at this moment cotton picker air draught stroke is finished, no corresponding negative pressure in this efficient cotton picking-up head, and this efficient cotton picking-up head enters the blade tooth active state; Afterwards, this efficient cotton picking-up head enters adopts cotton blade tooth mechanism, as shown in Figure 5, this moment, the elastic restoring force at boll hull 6 and elastic valve 4 reached under the external force effect of moving efficient cotton picking-up head, blade tooth 3 is outwards moved, and insert in the cotton that does not enter fully in the efficient cotton picking-up head, under the effect of moving efficient cotton picking-up head, cotton is grabbed down then; At last, when cotton picker enters next air draught stroke, with a suction cotton picker of the cotton under grabbing air draught road, as shown in Figure 6; The harvesting process is finished in circulation and so forth.

The utlity model has simple in structure, volume is little, in light weight, easy to use, the characteristics such as cost is low, make Use this high Performance cotton picking-up head, not only can adapt to the harvesting of variety classes cotton under the general planting conditions, and energy Increase net picking rate, improve the quality of cotton picking efficient and institute's cotton picking.
