RU2555428C1 - Header for stripping standing crops - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: header for stripping standing crops comprises a gauge platform 1 with support shoes 2, guiding cases 3 and 4, a drum 5, an auger 10, an unloading device 11 with a fan 12. Along the perimeter of the drum 5 the stripping combs 6 are fixed with teeth and holes in places of connection of their side edges at the base of the tooth 7. The drum 5 in the cross section has a shape of a regular polyhedron and formed of separate faces 13. These faces 13 have on the sides a flange, on one of which the stripping comb 6 teeth is made, so that the stripping comb 6 with teeth is made in one piece with a separate face 13. The assembly of the drum 5 can be carried out using contact welding.

EFFECT: reduction of complexity of manufacturing the stripping drum, reduction of the range of parts and the weight of the finished product.

Description

The invention relates to agricultural machinery and can be used in reapers for towing crops on the vine.

Known single-drum combing adapter company Shelburn-Reynolds. England (see the journal "Rural Machine Operator No. 8, 2013, an article by E.V. Zhalnin," Cleaning with a strip on the vine: the pros and cons "p.10, 11, 12), containing a casing with height adjustment, accepting stalks, combing drum with 8 rows of combs, combs with combing teeth, adapter body, feed conveyor, header auger.

The main disadvantage of this adapter is that the combing drum has a large manufacturing complexity and weight.

A well-known combing header of the British company Shelbourne Reynolds (see http://www.trizminsk.org/e248013.htm A. Skuratovich, P. Chuksin, N. Shpakovsky “Improving the combing header using the method of“ FSA + TRIZ. ”), Containing combing rotor with 8 rows of combs with combing teeth, header body, auger.

The disadvantage of this header is that the combing drum has a large manufacturing complexity and weight.

The purpose of the invention:

1. To reduce the complexity of manufacturing a stripping drum.

2. Reduce the range of parts.

3. Reduce weight.

This goal is achieved by the fact that the drum in the cross section has the shape of a regular polyhedron and is formed of individual faces having flanges on the sides, on one of which a comb comb with teeth is made, that is, the comb comb with teeth is made in one piece with a separate face, while drum assembly can be done by resistance welding.

Transverse stiffeners are made on each individual face.

Figure 1 shows the header for combing crops on the vine, left view; figure 2 - combing comb, made in one piece with a separate face, General view, in a perspective view; figure 3 is a cross section of a drum.

The inventive header for towing crops on the vine (Fig. 1) contains a copying platform 1 with support shoes 2 and guide covers 3 and 4, a drum 5, on which around the perimeter are fixed combing combs 6 with teeth 7 and holes 8 at the junction points side edges 9 at the base of the tooth 7 (figure 2), auger 10, unloading device 11 with a fan 12.

The drum 5 in cross section has the shape of a regular polyhedron (figure 3) and is formed of oval faces 13 having flanges on the sides 14, on one of which a combing comb 6 with teeth 7 is made, that is, the combing comb 6 with teeth 7 is made one a part with a separate face 13, while the Assembly of the drum 5 can be carried out using resistance welding.

On each individual face 13 there are transverse stiffeners 15.

The harvester for harvesting crops at the root is aggregated with energy (not shown in Fig.)

When moving the header for towing crops on the vine (Fig. 1), the copying platform 1, relying on the support shoes 2, copies the relief of the field. A drum 5, on which stripping combs 6 with teeth 7 and holes 8 are fixed around the perimeter of the joints of their lateral edges 9 at the base of the tooth 7, comb the plant stems from the bottom up and directs them along the lateral edges 9 of the tooth 7 into the holes 8.

With further rotation of the drum 5, the ears, having reached the stop of the edges of the hole 8, are torn off and the combing comb 6, made with one piece with a separate face 13, goes to the screw 10, sliding along the guiding casings 3 and 4. Next, the ears 10 are fed into the unloading device 11 and a fan 12 are sent to a container of a nearby vehicle (not shown in FIG.).

The presence of flanging 14 on a separate face 13 allows the assembly of the drum 5 to be produced by resistance welding, and the transverse stiffening ribs 15 can be used to increase the strength of the individual face 13 of the drum 5 and reduce the consumption of metal in its manufacture.

Due to the reduction of stamping operations in the manufacture of a separate face 13, due to the fact that the combing comb 6 is made of one piece with a separate face 13, it allowed to reduce the complexity of manufacturing the drum 5, reduce the range of parts and reduce its weight.

Using the proposed header for towing crops in the vine will allow:

1. To reduce the complexity of manufacturing a stripping drum.

2. Reduce the range of parts.

3. Reduce weight.

Claims (2)
