[0072] Combine the following Figure 1 and Fig.17 As shown, a double longitudinal axial flow drum feeding device for a harvesting machinery provided by the present application is described in detail.

[0073] In this embodiment, a double longitudinal axial flow drum feeding device for a harvesting machine is provided, which is combined with Figure 1-Figure 4 As shown, the double longitudinal axial flow drum feeding device of the harvester includes a main shaft 1, a feeding component and a diverter component 3.

[0074] Specifically, combined Figure 3 and Figure 4 As described above, seat bearings 45 are respectively installed at both ends of the main shaft 1 along the axial direction thereof, and a pulley assembly 46 is installed on the right side of the main shaft 1 .

[0075] Specifically, a plurality of feeding components are provided, and the plurality of feeding components are sleeved on the main shaft 1 at intervals along the axial direction of the main shaft 1, and the flow dividing component 3 is sleeved on the main shaft 1 and arranged between adjacent feeding components;

[0076] The feeding assembly includes a first fixed portion and a tooth 24 plate portion; the first fixed portion is arranged along the circumferential direction of the main shaft 1 and a feeding space is formed on the first fixed portion; the tooth 24 plate portion is arranged on the first fixed portion;

[0077] Specifically, the diversion component 3 includes a second fixed part and a diversion part; the second fixed part is sleeved on the main shaft 1, and the diversion part is arranged on the second fixed part. The diversion part forms a V-shaped diversion space 6 arranged in sequence along the circumferential direction of the main shaft 1, and the diversion space 6 is connected to the feeding space.

[0078] In summary, when the harvester starts to work, the external pulley transmits power to the main shaft 1, and the rotation of the main shaft 1 can drive the diverter component 3 and the feeding component to rotate. The diverter component 3 transfers the material transported by the harvester across the bridge to the feeding components on both sides, and utilizes the pushing action of the tooth 24 plate part on the feeding component and the friction action of the tooth 24 plate part to increase the movement speed of the material, thereby achieving the effect of forced feeding, increasing the feeding amount of the double longitudinal axial flow roller per unit time, and thus improving the operation efficiency of the harvester.

[0079] In this embodiment, the first fixing portion includes a wing member.

[0080] Specifically, the wing plate component includes a first wing plate and a second wing plate, Figure 6 As shown, the first wing plate includes a first base plate 11, a first vertical plate 12 and a second vertical plate 13; the first vertical plate 12 is arranged at one end of the first base plate 11 along the circumferential direction of the main axis 1 at a first preset angle, and the first vertical plate 12 is formed with first protrusions 14 arranged at intervals, and the second vertical plate 13 is arranged at the other end of the first base plate 11 along the circumferential direction of the main axis 1 at a second preset angle, and the second vertical plate 13 is formed with second protrusions 15 arranged at intervals; the first preset angle here is preferably 60°.

[0081] Specifically, combined Figure 7 As shown, the second wing plate includes a second base plate 16, a third vertical plate 17 and a fourth vertical plate 18; the third vertical plate 17 is arranged at one end of the second base plate 16 along the circumferential direction of the main axis 1 at a first preset angle, and the third vertical plate 17 is formed with third protrusions 19 arranged at intervals, and the fourth vertical plate 18 is arranged at the other end of the second base plate 16 along the circumferential direction of the main axis 1 at a second preset angle and the fourth vertical plate 18 is formed with fourth protrusions 20 arranged at intervals; preferably, the first preset angle here is preferably 142°, and the second preset angle is 98°.

[0082] Specifically, combined Fig. 9 As shown, the first protrusion 14 and the second protrusion 15 are arranged alternately, the third protrusion 19 and the fourth protrusion 20 are arranged alternately, and the first protrusion 14 and the fourth protrusion 20 correspond to each other, the second protrusion 15 and the third protrusion 19 correspond to each other, and the second vertical plate 13 and the third vertical plate 17 are connected by a first connecting member 21; further, combined with Figure 6 and Figure 7 As shown, there are four first protrusions 14, three second protrusions 15, three third protrusions 19, and four fourth protrusions 20. In the actual connection process, the three protrusions on the second vertical plate 13 correspond to the three fourth protrusions 20 on the third vertical plate 17 one by one, and the second vertical plate 13 and the third vertical plate 17 are connected together through the first connecting member 21. Preferably, the first connecting member 21 is a semicircular head bolt.

[0083] Specifically, combined Fig. 9 As shown, four wing plate components are provided, and the first vertical plate 12 in one of the adjacent wing plate components is connected to the fourth vertical plate 18 in another wing plate component through a first connecting member 21, so that the multiple wing plate components are arranged in sequence along the circumferential direction of the main shaft 1.

[0084] Specifically, combined Fig. 9 and Fig.17 As shown, the tooth plate portion includes a feeding tooth plate 22, and the connection between the second vertical plate 13 and the third vertical plate 17 in the same wing plate component and the connection between the first vertical plate 12 and the fourth vertical plate 18 in adjacent wing plate components are both provided with a feeding tooth plate 22.

[0085] Furthermore, combined with Figure 8 As shown, the feeding tooth plate 22 is a plate-shaped structure.

[0086] An oblong protrusion 23 is provided on one side of the feeding tooth plate 22 and a tooth 24 is provided on the end of the feeding tooth plate 22 away from the main shaft 1; oblong holes 25 are provided on the first protrusion 14 and the third protrusion 19. In the same wing plate component, the oblong protrusion 23 on the feeding tooth plate 22 can be inserted into the oblong hole 25 on the third protrusion 19; in adjacent wing plate components, the oblong protrusion 23 on the feeding tooth plate 22 can be inserted into the oblong hole 25 on the first protrusion 14.

[0087] Furthermore, a hole is provided on the oblong protrusion 23. For the same wing plate component, when the first connecting member 21 is used to connect the second vertical plate 13 and the third vertical plate 17, the first connecting member 21 can pass through the hole on the oblong protrusion 23, that is, the first connecting member 21 can be used to effectively connect the feeding tooth plate 22, the second vertical plate 13 and the third vertical plate 17.

[0088] Furthermore, since the first vertical plate 12 and the first bottom plate 11 form a first preset angle, and the third vertical plate 17 and the second bottom plate 16 form a first preset angle, when the feeding tooth plate 22 is connected to the first vertical plate 12 and the third vertical plate 17, it can be understood that the feeding tooth plate 22 forms a first preset angle with the radial direction of the main shaft 1, that is, the feeding tooth plate 22 and the main shaft 1 form a certain inclination angle (the inclination angle is the first preset angle, Fig.17 In actual use, it is found that the best feeding effect can be achieved when the inclination angle of the feeding tooth plate 22 and the main shaft 1 is opposite to the rotation direction of the main shaft 1.

[0089] More specifically, since the first protrusion 14 on the first vertical plate 12 on the wing plate component and the third protrusion 19 on the third vertical plate 17 are arranged in a staggered manner, because when the feeding tooth plate 22 is connected to the wing plate component, the feeding tooth plate 22 is arranged in a staggered manner on the wing plate component, this staggered arrangement can increase the surface roughness of the double longitudinal axial flow roller feeding device, and increase the feeding performance of the double longitudinal axial flow roller feeding device. The heat-treated feeding tooth plate 22 can increase the wear resistance of the double longitudinal axial flow roller feeding device. The angle between the feeding tooth plate 22 and the radial direction of the main shaft 1 makes the inclination direction of the feeding tooth plate 22 opposite to the rotation direction, which can increase the radial thrust of the double longitudinal axial flow roller feeding device on the material and increase the feeding performance.

[0090] Furthermore, the teeth 24 on the feeding tooth plate 22 increase the friction of the dual longitudinal axial flow drum feeding device on the material.

[0091] In this embodiment, combined Figure 6 and Figure 7 As shown, the feeding space includes a first feeding space 4 and a second feeding space 5. The first bottom plate 11, the first vertical plate 12 and the second vertical plate 13 surround the first feeding space 4, and the second bottom plate 16, the third vertical plate 17 and the fourth vertical plate 18 surround the second feeding space 5.

[0093] Specifically, combined Fig.15 , Fig.16 As shown, the left-hand spiral blade 27, the baffle 29 and the right-hand spiral blade 28 are connected in sequence and arranged in a V shape on the mounting base.

[0094] Specifically, a plurality of flow dividing components are provided, and the plurality of flow dividing components are arranged in sequence along the circumferential direction of the mounting base 26 , so that a V-shaped flow dividing space 6 is formed between adjacent flow dividing components.

[0095] Specifically, the left-directed spiral blades 27 of adjacent flow-dividing members are overlapped with the first vertical plate 12 and the second vertical plate of the wing plate member, respectively, so that the flow-dividing space 6 is connected with the feeding space.

[0096] Furthermore, the left-hand spiral blade 27 and the right-hand spiral blade 28 are both fixed to the mounting base 26 via a second connecting member 30. Preferably, the second connecting member 30 is a semicircular head bolt.

Fig.12 As shown, the second support member includes a third ring 39, a fourth ring 40 and a second support rod 41; the third ring 39 is sleeved on the main shaft 1, and the fourth ring 40 is sleeved on the third ring 39; one end of the second support rod 41 is connected to the third ring 39 and the other end is connected to the fourth ring 40, so that the fourth ring 40 is fixed to the third ring 39. Furthermore, a second keyway 55 is provided on the third ring 39, and the main shaft 1 cooperates with the second keyway 55 through a flat key, so that when the main shaft 1 rotates, the second support member can also rotate.

[0100] Furthermore, the third ring 39 is provided with third connecting holes 42 spaced apart along its circumferential direction, and the edge of the mounting base 26 is provided with fourth connecting holes 43. A fourth connecting member passes through the third connecting hole 42 and the fourth connecting hole 43 to fix the diverter member to the second support member.

[0101] Preferably, the fourth connecting member is a bolt.

[0102] Specifically, a third support member 49 is disposed between the first support member 31 and the second support member 51, between the first support member 53 and the second support member 52, and between the second support member 52 and the first second support member 51. Fig.14 As shown, the third support member 49 includes a second ring 35 and a fifth ring 50. The second ring 35 is sleeved on the main shaft 1, and the fifth ring 50 is sleeved on the second ring 35 through the third support rod 54. Furthermore, the first ring 34 and the second ring 35 are both spaced apart with first connecting holes 37 along their circumferential direction, and the first bottom plate 11 and the second bottom plate 16 are both provided with second connecting holes 38. The third connecting member passes through the first connecting hole 37 and the second connecting hole 38, so that the feeding assembly is fixed to the first support member and the third support member 49.

[0103] Preferably, the third connecting member is a bolt, that is, the first bottom plate 11 and the second bottom plate 16 are connected to the first ring 34 and the second ring 35 by bolts.

[0104] It is worth noting that: the first support member can transmit the rotational force of the main shaft to the wing plate component, so that the wing plate component rotates, the third support member 49 cannot transmit the rotational force of the main shaft to the wing plate component, and the third support member 49 only plays a supporting role for the wing plate component to prevent the wing plate component from being too long along the axial direction of the main shaft 1, and the wing plate component from collapsing in the middle due to gravity.

[0105] Similarly, the second support member No. 2 52 and the second support member No. 1 51 can transmit the rotational force of the main shaft 1 to the diverter component, that is, when the main shaft 1 rotates, the diverter component will rotate. As for the third support member 49 between the second support member No. 2 52 and the second support member No. 1 51, it cannot transmit the rotational force of the main shaft 1 to the diverter component, and only plays a supporting role for the diverter component to prevent the diverter component from being too long along the axial direction of the main shaft 1 and the diverter component from collapsing in the middle due to gravity.

[0106] In this embodiment, combined Fig.13 As shown, the double longitudinal axial flow drum feeding device of the harvesting machinery further includes a dustproof member 44, which is sleeved on the main shaft 1 and is respectively arranged between the first support member and the third support member 49, and between the third support member 49 and the second support member.

[0107] Specifically, since the first support member, the third support member 49 and the second support member all have a certain diameter, that is, they protrude from the main shaft 1, a gap is formed between the first support member and the third support member 49, and between the third support member 49 and the second support member. In order to prevent dust from entering the gap, a dustproof member 44 is provided. The dustproof member 44 can fill the gap to prevent a large amount of dust, straw, etc. from entering the gap, thereby ensuring the normal rotation of the feeding device without being disturbed by dust, straw, etc.

[0108] Furthermore, the dustproof member 44 includes two semi-cylinders, which are buckled on the main shaft 1, and the diameter of the dustproof member 44 is the same as the diameter of the first support member and the second support member.

[0109] Preferably, the dustproof member 44 is made of non-metallic material.

[0110] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
