Description

Technical Field

[0001] The utility model relates to the technical field of harvester feeding augers, in particular to a stalk feeding augers. Background Art

[0002] After corn is harvested, a large amount of straw is produced. The straw can be recycled, for example, it can be processed into feed for cattle and sheep. In order to recycle the straw, the current common models of stem-and-ear harvesting are used to harvest crops such as corn with ears and straw, which can achieve the simultaneous harvesting of straw and corn. The stem-and-ear harvesting harvesting table generally adopts a horizontal roller double-layer harvesting table structure, the upper harvesting table adopts an ear-picking harvesting table, and the lower harvesting table adopts a stem-feeding harvesting table. The feeding form of the lower harvesting table feeding auger is as follows:

[0003] 1. The telescopic ruler structure of the straw feeding auger has a weak feeding capacity when harvesting green and wet straw, and the straw cannot be fed into the feeding assembly at the rear side of the auger in time, which limits the operating efficiency of the whole machine.

[0004] 2. The scraper structure of the straw feeding auger. When there are many weeds in the straw field, the weeds are easily entangled at the auger feeding entrance, causing the feeding entrance to be blocked; at the same time, since the scraper is welded on the auger, it is easy to cause poor feeding when harvesting crops of different growth. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to improve the straw feeding capacity of the auger and avoid the phenomenon of poor feeding when harvesting crops with different growth potentials.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] The utility model provides a stalk feeding auger, comprising an auger shaft, wherein a conveying section and a feeding section are arranged on the auger shaft along its axial direction, and an auger blade is arranged on the conveying section; a mounting seat and a telescopic ruler are arranged on the feeding section, the mounting seat and the telescopic ruler are arranged alternately in the circumferential direction of the feeding section, a scraper is connected to the mounting seat; and the height of the scraper relative to the outer peripheral surface of the feeding section is adjustable.

[0008] The beneficial effects of the utility model are:

[0009] The utility model adopts the staggered arrangement of the telescopic ruler and the scraper in the circumferential direction of the feeding section, so that the stems are fed alternately, which effectively makes up for the problem of weak feeding capacity of the telescopic ruler, ensures the timely feeding of the stems, and improves the operation efficiency of the whole machine; at the same time, the height of the mounting seat is adjustable, which can adapt to the conditions of crops and weeds with different growth, avoids the phenomenon of poor feeding, and improves reliability.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the scraper is provided with a plurality of first long bolt holes, one side of the first long bolt hole along its own length direction is directly opposite to the auger shaft, and the scraper is connected to the mounting seat by bolts passing through the first long bolt holes.

[0012] The first bolt long hole can be used to facilitate adjustment of the height of the scraper relative to the outer peripheral surface of the feeding section, thereby adapting to crops of different growth potentials and facilitating operation.

[0013] Furthermore, the mounting seat is provided with a plurality of second long bolt holes, the length direction of the second long bolt holes is arranged along the axial direction of the auger shaft, and the bolts pass through the first long bolt hole and the second long bolt hole in sequence to connect the scraper to the mounting seat.

[0014] The second bolt long hole can be used to fine-tune the axial position of the scraper auger shaft to avoid interference between the scraper and the auger blades, making installation easy.

[0015] Furthermore, the side of the scraper away from the feeding section is a serrated edge.

[0016] The serrated edge can grab the stems and push them, which has a good feeding effect and improves the working efficiency.

[0017] Furthermore, the sawtooth tops of the sawtooth edge are provided with first rounded corners, and the grooves between adjacent sawtooths are provided with second rounded corners.

[0018] The first rounded corners prevent the saw teeth of the sawtooth edge from piercing into the stems and causing poor feeding, and at the same time prevent the sawtooth tips from curling and hooking weeds, causing weed entanglement; the second rounded corners prevent the stems, weeds, etc. from getting stuck in the grooves between adjacent saw teeth; effectively prevent the weeds from entanglement and the feeding port from being blocked.

[0019] Furthermore, the scraper is arranged obliquely relative to the radial cross section of the feeding section, and when the auger blades transport the stems to the feeding section under the action of rotation, the scraper pushes the stems away from the feeding section.

[0020] The inclined arrangement of the scraper can avoid the sawtooth edge digging into the stem and causing blockage of the cutting table feeding port.

[0021] Furthermore, the mounting seat is a V-shaped channel steel, both sides of the opening of the V-shaped channel steel are welded and fixed on the feeding section, and the scraper part is attached to one side of the V-shaped channel steel.

[0022] The structure has great strength and good stability; at the same time, the gap between the scraper and the mounting base is reduced to prevent weeds from getting stuck in the gap and forming entanglement.

[0023] Furthermore, two adjacent scrapers along the circumferential direction of the feeding section are respectively located at different axial positions of the feeding section.

[0024] Avoid any scraper occupying the space of the feeding section, avoid feeding too many stems at the same time to cause excessive stress, and avoid feeding difficulties; at the same time, each two adjacent scrapers alternately feed stems in different positions, which improves the feeding effect.

[0025] Furthermore, conveying sections are provided at both ends of the feeding section, and the rotation directions of the auger blades on the two conveying sections are opposite; among the two adjacent scrapers in the circumferential direction of the feeding section, one end of one scraper contacts with the auger blade on one of the conveying sections, and one end of the other scraper contacts with the auger blade on the other conveying section.

[0026] This avoids the entanglement of weeds and jamming of stems caused by gaps between the auger blades and the scraper, while ensuring the feeding of stems in the entire feeding section and improving the feeding effect.

[0027] Furthermore, the feeding section is a cylinder structure, and a guide seat for the telescopic ruler to pass through is provided on the wall surface of the cylinder structure; a floating seat is provided in the cylinder structure, and the telescopic ruler is hinged to the floating seat after passing through the guide seat.

[0028] The floating seat ensures the linkage of multiple telescopic rulers at the same axial position. Under the gravity of the telescopic ruler and the floating seat, when the telescopic ruler moves downward, it extends out of the surface of the feeding section; when the telescopic ruler moves upward, it retracts into the feeding section; at the same time, it avoids the telescopic ruler from being completely retracted into the feeding section, and has good reliability.

DETAILED DESCRIPTION

[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0036] This utility model refers to Figure 1-4 .

[0037] Embodiment 1, as Figure 1-3 As shown:

[0038] The utility model provides a stalk feeding auger, comprising an auger shaft 1, wherein a conveying section 6 and a feeding section 7 are provided on the auger shaft 1 along its axial direction, and an auger blade 2 is provided on the conveying section 6; a mounting seat 3 and a telescopic ruler 5 are provided on the feeding section 7, the mounting seat 3 and the telescopic ruler 5 are arranged alternately in the circumferential direction of the feeding section 7, a scraper 4 is connected to the mounting seat 3; and the height of the scraper 4 relative to the outer peripheral surface of the feeding section 7 is adjustable.

[0039] principle:

[0040] During installation, if Figure 4 As shown: the stem feeding auger is installed on the cutting table body 20, the feeding section 7 is opposite to the feeding port 21 of the cutting table body 20, one end of the auger shaft 1 extends out of the cutting table body 20 and is provided with a transmission sprocket 23, and the transmission sprocket 23 is used to connect to an external engine or other power equipment to transmit its power to the auger shaft 1.

[0041] When harvesting crops such as corn, the cutting table sends the stalks to the auger shaft 1. Under the rotation of the auger shaft 1, the auger blades 2 on the conveying section 6 send the stalks to the position of the feeding section 7. In the feeding section 7, under the rotation of the auger shaft 1, the telescopic ruler 5 and the scraper 4 act alternately to push or scrape the stalks from the feeding port 21 of the cutting table to the chopper 22, thereby realizing the feeding of the stalks. The height of the scraper 4 relative to the outer peripheral surface of the feeding section 7 is adjustable. The height of the scraper 4 can be adjusted according to the different growth of crops, weed conditions, etc., so as to be applicable under different working conditions and avoid the occurrence of poor feeding.

[0042] By adopting the utility model, the telescopic ruler 5 and the scraper 4 are arranged alternately in the circumferential direction of the feeding section 7, so that the stems are fed alternately, which effectively makes up for the problem of weak feeding capacity of the telescopic ruler 5, ensures the timely feeding of the stems, and improves the operation efficiency of the whole machine; at the same time, the height of the mounting seat 3 is adjustable, which can adapt to the conditions of crops and weeds with different growth, avoids the phenomenon of poor feeding, and improves reliability.

[0043] Further, such as Figure 3 As shown: the scraper 4 is provided with a plurality of first bolt long holes 8, one side of the first bolt long hole 8 along its own length direction is directly opposite to the auger shaft 1, and the scraper 4 is connected to the mounting seat 3 by bolts passing through the first bolt long holes 8.

[0044] Note: One side of the first bolt long hole 8 along its own length direction is opposite to the auger shaft 1: the two ends of the bolt hole generally refer to its axial ends, and one side generally refers to one side of its radial direction. The shape of the bolt long hole is long rather than round, so the shapes of its two sides are different, and it is necessary to distinguish between "one side along its own length direction" and "one side along its own width direction".

[0045] The first bolt long hole 8 can be used to facilitate adjustment of the height of the scraper 4 relative to the outer peripheral surface of the feeding section 7, so as to adapt to crops of different growth potentials and facilitate operation.

[0046] Further, such as Figure 1 As shown: a plurality of second long bolt holes 9 are provided on the mounting seat 3, and the length direction of the second long bolt holes 9 is arranged along the axial direction of the auger shaft 1, and the bolts pass through the first long bolt hole 8 and the second long bolt hole 9 in sequence to connect the scraper 4 to the mounting seat 3.

[0047] The second bolt long hole 9 facilitates fine adjustment of the axial position of the scraper 4 and the auger shaft 1 to avoid interference between the scraper 4 and the auger blade 2, thereby facilitating installation.

[0048] Furthermore, one side of the scraper 4 away from the feeding section 7 is a serrated edge 10 .

[0049] The serrated edge 10 can grab the stems and push them, which has a good feeding effect and improves the working efficiency.

[0050] Furthermore, the serrations of the serration edge 10 are provided with first rounded corners 11 at the tops of the serrations, and second rounded corners 12 are provided at the grooves between adjacent serrations.

[0051] Preferably, the radius of the first fillet 11 is 3 mm, the radius of the second fillet 12 is 10 mm, and the sawtooth height is 16 mm-24 mm. The width of the sawtooth is greater than the width of a stem to avoid tying the stem.

[0052] The first rounded corner 11 prevents the saw teeth of the serrated edge 10 from piercing into the stems and causing poor feeding, and at the same time prevents the saw teeth tips from curling and catching weeds, causing weed entanglement; the second rounded corner 12 prevents stems, weeds, etc. from getting stuck in the grooves between adjacent saw teeth; and effectively prevents weed entanglement and blockage of the feeding port 21.

[0053] Further, such as Figure 2 As shown, the scraper 4 is arranged obliquely relative to the radial cross-section of the feeding section 7, and when the auger blade 2 transports the stems to the feeding section 7 under the action of rotation, the scraper 4 pushes the stems away from the feeding section 7.

[0054] Note: When the auger blade 2 conveys the stems to the feeding section 7 under the action of rotation, the scraper 4 pushes the stems away from the feeding section 7, which limits the inclination direction of the scraper 4, that is, it inclines toward the back of the working surface.

[0055] The inclined arrangement of the scraper 4 prevents the sawtooth edge 10 from digging into the stem and causing the cutting table feeding port 21 to be blocked.

[0056] Furthermore, the mounting seat 3 is a V-shaped channel steel, both sides of the opening of the V-shaped channel steel are welded and fixed on the feeding section 7, and the scraper 4 is partially attached to one side of the V-shaped channel steel.

[0057] The structure has great strength and good stability; at the same time, the gap between the scraper 4 and the mounting seat 3 is reduced to prevent weeds from getting stuck in the gap and forming entanglement.

[0058] Further, such as Figure 1 As shown, two adjacent scrapers 4 along the circumferential direction of the feeding section 7 are respectively located at different axial positions of the feeding section 7.

[0059] Avoid any scraper 4 occupying the space of the feeding section 7, avoid feeding too many stems at the same time to cause excessive stress, and avoid feeding difficulties; at the same time, every two adjacent scrapers 4 alternately feed stems at different positions, thereby improving the feeding effect.

[0060] Furthermore, conveying sections 6 are provided at both ends of the feeding section 7, and the rotation directions of the auger blades 2 on the two conveying sections 6 are opposite; among the two adjacent scrapers 4 in the circumferential direction of the feeding section 7, one end of one scraper 4 contacts with the auger blade 2 on one of the conveying sections 6, and one end of the other scraper 4 contacts with the auger blade 2 on the other conveying section 6.

[0061] The gap between the auger blade 2 and the scraper 4 prevents weed entanglement and stem jamming, while ensuring the feeding of the stems in the full feeding section 7, thereby improving the feeding effect.

[0062] Further, such as Figure 1-2 As shown: the feeding section 7 is a cylinder structure, and a guide seat 13 for the telescopic ruler 5 to pass through is provided on the wall of the cylinder structure; a floating seat 14 is provided inside the cylinder structure, and the telescopic ruler 5 is hinged to the floating seat 14 after passing through the guide seat 13.

[0063] The floating seat 14 ensures the linkage of multiple telescopic rulers 5 at the same axial position. Under the gravity of the telescopic ruler 5 and the floating seat 14, when the telescopic ruler 5 moves downward, it extends out of the surface of the feeding section 7; when the telescopic ruler 5 moves upward, it retracts into the feeding section 7; at the same time, it avoids the telescopic ruler 5 from being completely retracted into the feeding section 7, and the reliability is good.
