Description

TECHNICAL FIELD

[0001] The present application relates to an agricultural machinery device, more particularly to a stalk conveying mechanism of a fresh corn harvester. BACKGROUND

[0002] Fresh corn refers to young corn with special flavor and quality. Compared with ordinary corn, fresh corn is more tender, so the cutting and earing structure of the traditional corn harvester is more likely to cause the fresh corn to be squeezed and damaged or to fall off and be damaged during conveying. Therefore, the machinery for harvesting fresh corn must consider minimizing the squeezing of the corn with high strength or the falling of the corn at a high place during conveying. The present application is to innovatively design the conveying structure of the stalk to improve the protection of the corn during the conveying and earing process and reduce the damage to the corn. SUMMARY

[0003] In view of the deficiencies of the prior art, the purpose of the present application is to provide a stalk conveying mechanism of a fresh corn harvester, which can orderly convey the corn stalks and complete the smoother separation of the corn and the stalks by upward conveying, reduce the squeezing and impact of the corn during the orderly processing of the stalks, reduce the damage, and improve the qualified rate of the harvested fresh corn.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a stalk conveying mechanism of a fresh corn harvester, comprising a layout frame, a cutting knife for cutting the corn stalks arranged below the front part of the layout frame, a pushing mechanism for pushing and conveying the corn rearward arranged at the rear sequence position of the cutting knife in the middle part of the layout frame, and a conveying mechanism for conveying and cutting the corn stalks upward arranged at the rear sequence position of the pushing mechanism in the rear part of the layout frame, wherein the conveying mechanism comprises a turnover receiving mechanism, a resistance discharging mechanism, a clamping conveying mechanism, and a clamping cutting mechanism arranged in sequence from bottom to top on the layout frame, the middle part of the turnover receiving mechanism is provided with a gap for the corn stalks to pass through, the corn is opened and passes through by the turnover itself, the middle part of the resistance discharging mechanism is provided with a gap for the corn stalks to pass through, the resistance discharging mechanism blocks the corn to separate the corn root from the stalk, the corn falls to the turnover receiving mechanism and discharges to the outside, the clamping conveying mechanism clamps the corn stalks and conveys the stalks upward when driven, and the clamping cutting mechanism clamps the corn stalks and cuts the stalks when driven.

[0005] As an improvement, the clamping conveying mechanism comprises a pair of clamping rollers, a first driving cylinder for driving the clamping rollers to approach and move away from each other, and a first driving motor for driving the clamping rollers to rotate. The clamping rollers are folded to clamp the corn stalks under the driving of the first driving cylinder, and the stalks are conveyed upward when the first driving motor works.

[0006] As an improvement, the clamping and chopping mechanism includes a pair of chopping rollers, a second drive cylinder that drives the chopping rollers to move closer and further apart, and a second drive motor that drives the chopping rollers to rotate. The chopping rollers close together to clamp the corn stalks under the drive of the second drive cylinder, and chop the stalks and discharge them upwards when the second drive motor is working.

[0007] As an improvement, a blower mechanism is also provided on the upper side of the clamping and chopping mechanism, so that the stems chopped by the clamping and chopping mechanism are blown outward by the blower mechanism and fall back into the field.

[0008] As an improvement, the flipping receiving mechanism includes a pair of tilted flipping plates and an elastic element disposed at the lower part of the flipping plates. The outer side of the flipping plates is flipped on the arrangement frame, and the pair of flipping plates are arranged with the outer side lower and the inner side higher, and the opposite inner sides form a gap for the corn stalks to pass through. When the corn comes into contact with the flipping plates, the flipping plates flip to make way for the corn. After the corn passes through the flipping plates, the elastic element drives the flipping plates to reset.

[0009] As an improvement, the anti-contact feeding mechanism includes a pair of inclined anti-contact plates, which are arranged with the outer side higher than the inner side. The outer side of the anti-contact plates is installed on the arrangement frame, and the opposite inner side forms a gap for the corn stalks to pass through. When the corn reaches the anti-contact plate, it is blocked and the stalks are broken off at the root as they continue to be conveyed upward. The corn is received by the flipping plate and falls outward along the flipping plate.

[0010] As an improvement, the tipping and receiving mechanism also includes a receiving conveyor belt, which is set on the outside of the tipping plate to receive falling corn. The receiving conveyor belt is arranged at an incline along the front-to-back direction for conveying and collecting the corn backward.

[0011] As an improvement, the inner sides of the flip plate and the contact plate are provided with several clearance grooves along the width direction, which are used to allow branches on the corn stalk to pass through.

[0012] As an improvement, the actuating mechanism includes a rotating shaft and several arc-shaped actuating rods evenly arranged on the rotating shaft. When the rotating shaft rotates, the inner side of the arc of a certain arc-shaped actuating rod catches the corn stalk and conveys it to the subsequent conveying mechanism.

[0013] As an improvement, the lower part of the conveying mechanism is also equipped with a liftable trolley, which is used to support the bottom of the corn stalks and moves upward synchronously when the clamping conveying mechanism starts to convey the stalks upward.

[0014] The beneficial effects of this invention are:

[0015] 1. By cutting and conveying horizontally, the corn stalks are sent to the subsequent conveying and ear-harvesting space, which can effectively realize the transfer of stalks in space. The overall structure is simple and occupies little space.

[0016] 2. By configuring the functions of each part of the conveying mechanism in the vertical direction, the corn stalks are conveyed upwards and chopped, while the stalks are blocked and separated from the corn along the growth direction, thus reducing bumps and damage to the corn and improving the qualified rate of fresh corn harvest.

[0017] 3. The overall mechanism can be used individually on the front of small harvesting vehicles or arranged in parallel in groups on the front of large harvesting vehicles, making it flexible in use and applicable to a wide range of scenarios. Attached Figure Description

[0024] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , 2 Figures 3, 4, 5, and 6 show specific embodiments of the stalk conveying mechanism of the fresh corn harvester of the present invention. The figures only illustrate the mutual cooperation between the structures. The position and size ratio of the specific structures can be reasonably adjusted according to the actual product situation, and do not limit the scope of protection of the present invention.

[0026] The specific embodiment includes an arrangement frame 1. A cutting blade 11 for cutting corn stalks is provided at the lower front of the arrangement frame 1. A pushing mechanism 12 for pushing and conveying corn backwards is provided in the middle of the arrangement frame 1 after the cutting blade 11. A conveying mechanism 13 for conveying and cutting corn stalks upwards is provided in the rear of the arrangement frame 1 after the pushing mechanism 12. The conveying mechanism 13 includes a flipping receiving mechanism 2, an abutting feeding mechanism 3, a clamping conveying mechanism 4, and a clamping and chopping mechanism 5 arranged sequentially from bottom to top on the arrangement frame 1. The flipping receiving mechanism 2 has a gap in the middle for the corn stalks to pass through. It flips itself to allow the corn to push open and pass through. The abutting feeding mechanism 3 has a gap in the middle for the corn stalks to pass through. It blocks the corn, causing the corn roots to separate from the stalks. The corn falls to the flipping receiving mechanism 2 and falls outwards. The clamping conveying mechanism 4 clamps the corn stalks and conveys them upwards when driven. The clamping and chopping mechanism 5 clamps the corn stalks and chops them when driven.

[0027] When using this invention, depending on the harvesting scenario, the stalk conveying mechanism can be applied alone to the front of a small harvesting vehicle for single-row harvesting of corn in a small area; or it can be applied in parallel groups to the front of a large harvesting vehicle for multi-row harvesting of corn in a large area. The arrangement frame 1 is installed at the front of the harvester's frame, with the cutting blade 11 at the very front. Correspondingly, guides for guiding corn stalks can be set on both sides above the cutting blade 11 to accurately guide the corn to the position directly opposite the cutting blade 11. The cutting blade 11 cuts the root of the corn stalk. The corn stalk is then pushed backward by the activated actuating mechanism 12 and enters the space where the conveying mechanism 13 is located. Specifically, this is the space for accommodating corn stalks formed between the flipping receiving mechanism 2, the contact feeding mechanism 3, the clamping conveying mechanism 4, and the clamping chopping mechanism 5. The flipping receiving mechanism 2, the contact feeding mechanism 3, the clamping conveying mechanism 4, and the clamping chopping mechanism 5 are located at the upper part of this space, so that the corn is positioned below the flipping receiving mechanism 2 when entering the space. The clamping conveying mechanism 4 and the clamping chopping mechanism 5 first clamp the upper end of the corn stalk from above to keep the stalk upright and stable. The flipping receiving mechanism 2 and the contact feeding mechanism 3 assist in keeping the stalk upright on both sides. By activating the clamping and conveying mechanism 4, power is provided to the stalks to transport them upwards. Simultaneously, the clamping and chopping mechanism 5 is activated, continuously chopping the stalks transported to the clamping and chopping mechanism 5. The corn, branching off from the stalks, forms an outward-sloping angle with the stalk as its central axis. During the upward transport process, the outward-sloping corn, upon reaching the turning and receiving mechanism 2, will push open the turning and receiving mechanism 2 as it continues to rise. After the corn passes, the turning and receiving mechanism 2 will reset and then wait to receive more corn. When the corn reaches the abutment feeding mechanism 3, it will be blocked. As the stalks continue to be conveyed upwards, the corn and stalks form a downward-bending structure until the corn root is broken, thus completing the separation. The falling corn falls directly onto the flipping and receiving mechanism 2 and is output outwards. This separation action avoids impact damage to the corn, allowing it to separate from the stalks in its natural growth state, thus better protecting the corn. Furthermore, the corn is directly received by the flipping and receiving mechanism 2, minimizing the impact of falling corn and improving the quality rate of fresh corn harvest. The stalks are continuously conveyed upwards to complete the chopping operation, and can be reused through a further constructed collection or discharge mechanism, returning to the field as fertilizer. The overall structure of this invention occupies little space, significantly reducing the size of the harvester while achieving the corn harvesting function.

[0028] As an improved specific implementation, the clamping and conveying mechanism 4 includes a pair of clamping rollers 41, a first drive cylinder 42 that drives the clamping rollers 41 to move closer and further apart from each other, and a first drive motor 43 that drives the clamping rollers 41 to rotate. The clamping rollers 41 close and clamp the corn stalks under the drive of the first drive cylinder 42, and convey the stalks upward when the first drive motor 43 is working.

[0029] like Figure 2 As shown, in the initial state, a pair of clamping rollers 41 are driven to separate from each other by the first drive cylinder 42, providing space for the corn stalk to enter from the side. After the stalk reaches between the pair of clamping rollers 41, the first drive cylinder 42 closes the clamping rollers 41 to stably clamp the stalk. When the first drive motor 43 is started, the pair of clamping rollers 41 rotate synchronously to transport the stalk upward.

[0030] As an improved specific implementation, the clamping and chopping mechanism 5 includes a pair of chopping rollers 51, a second drive cylinder 52 that drives the chopping rollers 51 to move closer and further apart from each other, and a second drive motor 53 that drives the chopping rollers 51 to rotate. The chopping rollers 51 close and clamp the corn stalks under the drive of the second drive cylinder 52, and chop the stalks and discharge them upward when the second drive motor 53 is working.

[0031] like Figure 2 As shown, in the initial state, a pair of chopping rollers 51 are driven to separate from each other by the second drive cylinder 52, providing space for the corn stalks to enter from the side. After the stalks reach between the pair of chopping rollers 51, the second drive cylinder 52 closes the chopping rollers 51 to confine the stalks between them. When the second drive motor 53 is started, the pair of chopping rollers 51 rotate synchronously to chop the stalks and discharge them upwards.

[0032] As an improved specific implementation, a blower mechanism 6 is also provided on the upper side of the clamping and chopping mechanism 5, so that the stems chopped by the clamping and chopping mechanism 5 are blown outward by the blower mechanism 6 and fall back into the field.

[0033] like Figure 2 As shown, for the stems chopped by the clamping and chopping mechanism 5, the blower mechanism 6 directly blows the chopped, lighter, and more scattered stem residue outward from the space where the conveying mechanism 13 is located. This prevents the chopped stems from falling and contaminating the mechanism below, and allows the chopped stems to fall back into the field for recycling as fertilizer, thus eliminating the need for collection and processing.

[0034] As an improved specific implementation, the flipping receiving mechanism 2 includes a pair of inclined flipping plates 21 and an elastic member 22 disposed at the lower part of the flipping plates 21. The outer side of the flipping plates 21 is flipped and disposed on the arrangement frame 1, and the pair of flipping plates 21 are arranged with the outer side lower and the inner side higher, and the opposite inner sides form a gap for the corn stalk to pass through. When the corn comes into contact with the flipping plates 21, the flipping plates 21 flip to make way for the corn. After the corn passes through the flipping plates 21, the elastic member 22 drives the flipping plates 21 to return to their original position.

[0035] like Figure 2 As shown, a pair of flipping plates 21 initially form a figure-eight structure, with a gap between them allowing the stalk to pass through, and the plates on both sides abutting the stalk to help it remain upright. When the corn is conveyed upwards against the flipping plates 21, the outwardly tilted corn will push the flipping plates 21 upwards (see attached diagram). Figure 6 In the state of the corn, the top of the corn and the top ear participate in the action of opening the flipping plate 21, which plays a good buffering role and will not damage the corn body. During the flipping process, the elastic element 22 is stretched and stores force; after the corn passes through the flipping plate 21, the elastic element 22 releases the elastic force to reset the flipping plate 21 and return to the original tilted state to wait for the corn.

[0036] As an improved specific implementation, the anti-contact feeding mechanism 3 includes a pair of inclined anti-contact plates 31. The pair of anti-contact plates 31 are arranged with the outer side higher than the inner side. The outer side of the anti-contact plates 31 is installed on the arrangement frame 1, and the opposite inner side forms a gap for the corn stalk to pass through. When the corn reaches the anti-contact plate 31, it is blocked and the root is broken off during the upward conveying of the stalk. The corn is received by the flipping plate 21 and falls outward along the flipping plate 21.

[0037] like Figure 2 As shown, a pair of contact plates 31 form an inverted V-shape structure, with a gap between them allowing the stalk to pass through, and the plates on both sides of the stalk help maintain its upright position. When the corn is conveyed upwards to the contact plates 31, it is blocked, and the corn tilts outwards at an angle that adapts to the tilt angle of the contact plates 31 (see attached diagram). Figure 6 As the stalk continues to be conveyed upwards, the corn and stalk will be in a downward bending motion until the corn root is broken off, thus completing the separation. The falling corn will fall directly onto the nearby flipping plate 21. This separation motion of corn and stalk avoids the impact damage to the corn caused by the traditional corn and stalk separation structure. Moreover, the corn is directly received by the flipping plate 21 and conveyed to the outside, reducing the impact of falling corn.

[0038] As an improved specific implementation, the flipping and receiving mechanism 2 also includes a receiving conveyor belt 23, which is disposed on the outside of the flipping plate 21 to receive falling corn. The receiving conveyor belt 23 is arranged in an inclined state along the front-back direction for conveying and collecting corn backward.

[0039] like Figure 2 , 6 As shown, the corn received by the tilting plate 21 rolls outward along the inclined surface of the tilting plate 21 to the receiving conveyor belt 23. The receiving conveyor belt 23 is arranged in the front-to-back direction according to the structure of the fresh corn harvester, thereby conveying the corn backward to the collection box. The receiving conveyor belt 23 is set in an inclined state, which can convey the corn to the high point of the output end, thereby completing the transfer corresponding to the high opening of the collection box.

[0040] As an improved specific implementation, the inner sides of the flip plate 21 and the contact plate 31 are provided with a plurality of clearance grooves 32 along the width direction, which are used to allow branches on the corn stalk to pass through.

[0041] like Figure 3 , 4 As shown, the stalk also has some branches, which will abut against the flipping plate 21 and the contact plate 31 when they reach them. To improve the smoothness of the branches passing through the gap between the flipping plate 21 and the contact plate 31, several clearance grooves 32 are further provided along the width direction. The branches can pass through the clearance grooves 32 and be conveyed upwards, thereby avoiding the flipping plate 21 from being flipped due to the large resistance between the branches and the flipping plate 21, and also avoiding the possibility of breakage due to the large resistance between the branches and the contact plate 31, thus preventing the branches from falling onto the flipping plate 21 and being collected. Furthermore, the size of the clearance groove 32 is designed to be smaller than the diameter of the stalk and the corn to prevent them from getting stuck.

[0042] As an improved specific implementation, the inner side of the flip plate 21 is provided with a rubber edge 24 along the width direction.

[0043] like Figure 3 As shown, after the corn passes through the flipping plate 21, the elastic element 22 releases its elastic force to reset the flipping plate 21. The inner side of the flipping plate 21 will scratch the corn husk. By setting the rubber edge 24, the edge of the flipping plate 21 is prevented from scratching the corn husk, ensuring that the appearance of the corn is intact and undamaged.

[0044] As an improved specific implementation, a cutting blade 33 is provided on the inner side of the contact plate 31 extending downward along the width direction.

[0045] like Figure 2 , 6As shown, when the corn is conveyed upward to the contact plate 31, it is blocked. The cutting blade 33 will contact the root of the corn to create a cutting mark. As the stalk continues to be conveyed upward, the breaking action will guide the corn and stalk to break from the position of the broken mark, thereby making the separation of the corn smoother and reducing the compression time between the corn and the contact plate 31.

[0046] As an improved specific implementation, the actuating mechanism 12 includes a rotating shaft 121 and a plurality of arc-shaped actuating rods 122 evenly arranged on the rotating shaft 121. When the rotating shaft 121 rotates, the inner side of the arc of a certain arc-shaped actuating rod 122 catches the corn stalk and conveys it to the subsequent conveying mechanism 13.

[0047] like Figure 1 , 5 As shown, the arc-shaped actuating rod 122 extends forward and backward in space. Specifically, the arc-shaped actuating rod 122 can rotate to a position above the cutting blade 11, and is offset from the guide in height to avoid interference. Furthermore, the arc-shaped actuating rod 122 can rotate into the space of the conveying mechanism 13, and is positioned below the flipping receiving mechanism 2 in height, thus avoiding interference. After the cutting blade 11 completes the cutting of a corn stalk, the rotating shaft 121 is activated, causing one of the arc-shaped actuating rods 122 to rotate at a certain angle, so that the inner arc of the arc-shaped actuating rod 122 catches the corn stalk and conveys it to the subsequent conveying mechanism 13. When the corn stalk is conveyed to the cutting blade 11, and when the conveying mechanism 13 is conveying upwards for ear picking and stalk chopping, the arc-shaped actuating rod 122 can rotate to the side without affecting the normal conveying of the stalk and corn. The arc-shaped actuating lever 122 is preferably arranged in three sets evenly on the rotating shaft 121, forming a 120-degree interval. As the operation completes a 120-degree rotation, it conveys the corn stalks.

[0048] As an improved specific implementation, the lower part of the conveying mechanism 13 is also provided with a liftable trolley 7, which is used to support the bottom of the corn stalk and moves upward synchronously when the clamping conveying mechanism 4 starts to convey the stalk upward.

[0049] like Figure 2 As shown, before the clamping and conveying mechanism 4 clamps and positions the stalks, the lower support frame 7 can support the corn stalks. Its initial state can be kept at the same height as the cutting blade 11. When the clamping and conveying mechanism 4 is started, the support frame 7 can be driven by, for example, a cylinder to rise and support the corn stalks, thereby improving the stability of the stalk conveying. The distance of its rise and support can be selected as needed. After the corn stalks are conveyed, chopped, and the corn is separated, the overall weight will be reduced to a certain extent, and the auxiliary support of the support frame 7 will no longer be needed. The support frame 7 can then be reset to wait for the next stalk to be supported.

[0050] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
