Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The proposed header for stripping of standing crops comprises a gauge housing 1 with a guide casing 2, a drum 3, on which the stripper combs 4 with the teeth 5 are mounted uniformly around the entire perimeter, a screw 9 with the double-threaded spiral bands 10 along the edges and the inclined oval disc 11 in the middle part, with two oval half-disks 12 mounted on it with the ability of motion, a feed elevator 13 with a conveyor 14 with elastic planks 15, and bearing shoes 16. The stripper comb 4 with the teeth 5 is mounted on the drum 3 from its centre to the periphery in both directions at an angle to the drum 3 generatrix. The side edges of the teeth 5 are arranged as a "dovetail" with the openings at their connection sites and form an acute angle at the apex of the tooth. The openings at the connection sites of the side edges of the teeth 5 of the stripper comb 4 have sharp edges.

EFFECT: invention provides reduction in power consumption, the header weight and percentage of damage to grain.

Description

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

Known single-drum combing adapter company "Shelburn-Reynolds", England (see. Well. "The rural machine operator", 2013, No. 8, article: Zhalnina E.V. Cleaning with a pile on the vine: for and against, pp. 10-12 ) containing a casing with height adjustment, receiving stems, combing drum with 8 rows of combs, combs with combing teeth, adapter housing, feeding conveyor, header auger.

The main disadvantage of this adapter is that for harvesting plants on the vine, considerable power is required in connection with the arrangement of the combs on the drum in rows.

In addition, the header has a large mass.

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

The disadvantage of this reaper is that for combing plants on the vine, considerable power is required due to the fact that the combs on the drum are arranged in rows.

The purpose of the invention:

1. Reduce power consumption for stripping.

2. Reduce header weight.

3. Reduce the percentage of injury to the grain.

This goal is achieved by the fact that the comb comb with teeth is mounted on the drum from its middle to the periphery on both sides at an angle to the drum generatrix, while the hole at the junction of the side edges of the teeth of the comb comb has sharp edges.

The angle of inclination of the combing comb with teeth mounted on the drum from its middle to the periphery on both sides is equal to or less than half the acute angle of the top of the tooth of the combing comb.

The sides of the guide casing of the header body of the header have a narrowing towards the auger.

Oval half-disks of the screw can be made of elastic material.

Thus, the claimed header for towing crops in the bud meets the criterion of "Novelty."

Signs that distinguish the claimed technical solution from the prototype in other technical solutions in this area are not identified, which allows us to conclude that the inventive header for towing crops in the bud meets the criterion of "significant differences".

Figure 1 shows the header for combing crops on the vine, left view; figure 2 - comb with teeth, top view; figure 3 - header, top view; figure 4 - drum combing comb, in a perspective view; figure 5 is a section aa of figure 2.

The inventive header for towing crops on the vine (Fig. 1) comprises a copying body 1 with a guiding casing 2, a drum 3, on which the combing combs 4 with teeth 5 are evenly fixed around the perimeter, the side edges 6 of which are located in the form of a “dovetail” with a hole 7 at their junctions and forming an acute angle α ° at the apex 8 of tooth 5 (Fig. 2), a screw 9 with double-helical spiral bands 10 along the edges and an inclined oval disk 11 in the middle part, with two mounted on it oval 12 half-disks (3), an inclined portion 13 with the conveyor 14 with elastic straps 15 and 16 supporting shoes.

The combing comb 4 with teeth 5 is mounted on the drum 3 from its middle to the periphery on both sides at an angle β ° to the generatrix 17 of the drum 3 (figure 4), while the hole 7 at the junction of the side edges 6 of the teeth 5 of the combing comb 4 has sharp edges (figure 5).

The angle β ° of inclination of the combing comb 4 with teeth 5 mounted on the drum 3 from its middle to the periphery on both sides is equal to or less than half of the acute angle α ° of the top 8 of tooth 5 of the combing comb 4 4 β≤1 / 2 · α °.

The sides 18 of the guide casing 2 of the header body 1 of the header have a narrowing towards the screw 9.

Oval half disks 12 of the screw 9 can be made of elastic material.

When the combine is moving, the copying case 1 (Fig. 1), relying on the support shoes 16, copies the relief of the field. Drum 3, on which the combing combs 4 with teeth 5 are evenly fixed throughout the parameter, the side edges 6 of which are located in the form of a “dovetail” with a hole 7 at their junctions and forming an acute angle α ° at the top 8 of tooth 5 (Fig. 2 ), comb the stems of plants from the bottom up and along the lateral edges 6 of the tooth 5 with an acute angle α ° go into the holes 7.

With further rotation of the drum 3, the ears, reaching the stop of the sharp edges of the hole 7, are cut off and the combing comb 4 is directed to the screw 9 (Fig. 3) with double-entry spiral ribbons 10 along the edges and an inclined oval disk 11 in the middle part with the possibility of being installed on it moving two oval half-discs 12.

Due to the fact that the combing comb 4 with teeth 5 (Fig. 4) is mounted on the drum 3 from its middle to the periphery on both sides at an angle β ° to the generatrix 17, which is equal to or less than half of the acute angle α ° of the tooth top 5 combing combs 4 β≤1 / 2 · α °, then the ears, reflected from the combing comb 4, will be guided along the tapering sidewalls 18 of the guide casing 2 of the header copy body 1.

Next, the ears of oval half disks 12 of the screw 9, which can be made of elastic material, are sent to the inclined chamber 13, then the conveyor 14 with elastic straps 15 are fed into the thresher of the combine.

Due to the fact that the combing comb 4 with teeth 5 is mounted on the drum 3 from its middle to the periphery on both sides at an angle β ° to the generatrix 17 of the drum 3, the power consumption for combing crops is reduced.

The presence of sharp edges (figure 5) in the hole 7 at the junction of the side edges 6 of the teeth 5 of the combing comb 4 allows you to cut the ears, and not tear off.

The implementation of the angle β ° of inclination of the combing comb 4 with teeth 5 equal to or less than half of the acute angle α ° of the top of tooth 5 of the combing comb β≤1 / 2 · α °, provides unhindered entry of agricultural stems between the teeth 5.

The implementation of the sides 18 of the guide casing 2 of the header copying body 1 tapering towards the screw 9 allows the header copying body 1 and the screw 9 to be made smaller, which reduces the weight of the header.

The use of oval half-disks 12 made of elastic material can reduce the percentage of injury to the grain.
