[0037] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1 As shown, this embodiment of the invention provides a corn stalk harvesting and bundling device, including a connecting frame 1, a cutting mechanism 2, a gathering mechanism 3, a conveying mechanism 4, a bundling mechanism 5, a straightening mechanism 6, a machine head 8, and a rolling unit 9.

[0039] The machine head 8 is positioned in front of the connecting frame 1 in the forward direction, and the rolling unit 9 is positioned below the connecting frame 1. The machine head 8 drives the connecting frame 1 forward. The cutting mechanism 2, the gathering mechanism 3, the conveying mechanism 4, the bundling mechanism 5, and the straightening mechanism 6 are sequentially arranged on the connecting frame 1, with the cutting mechanism 2 being the front end of the connecting frame 1 in the forward direction.

[0040] The system comprises several mechanisms: a cutting mechanism 2 for cutting corn stalks, a gathering mechanism 3 for gathering the cut corn stalks and conveying them to a conveying mechanism 4, which then transports them to a bundling mechanism 5. The bundling mechanism 5 bundles the corn stalks, and the conveying mechanism 4 continues to transport the bundled corn stalks to a straightening mechanism 6, which erects the bundled corn stalks in the field. This system mechanizes the harvesting of whole corn stalks, reducing the high cost of whole-stalk harvesting and improving harvesting efficiency.

[0041] In the actual application process, when the conveying mechanism 4 conveys the corn stalks to the bundling mechanism 5, the corn stalks only partially enter the bundling mechanism 5, and when the bundling mechanism 5 finishes bundling, the conveying mechanism 4 conveys the remaining corn stalks to the righting mechanism 6.

[0042] As shown in Figure 1 and Figure 2 The cutting mechanism 2 includes two groups of cutting assemblies 21 arranged on the connecting frame 1. Each group of cutting assemblies 21 includes a disc cutting knife 211, a rotating power unit 212, and a lifting unit 213. The lifting unit 213 is arranged on the connecting frame 1, and the lifting unit 213 drives the disc cutting knife 211 to move up and down through the rotating power unit 212. The output end of the rotating power unit 212 is connected to the rotation center of the disc cutting knife 211 to drive the disc cutting knife 211 to rotate along its own axis. The shortest interval between the disc cutting knives 211 of the two groups of cutting assemblies 21 is less than the diameter of the corn stalks, that is, the shortest distance between the arc-shaped parts of the two disc cutting knives 211. The disc cutting knives 211 of the two groups of cutting assemblies 21 rotate in opposite directions to cut the corn stalks in the interval. In the actual application process, the two groups of cutting assemblies 21 are opposite to a row of corn stalks, the connecting frame 1 is driven by the machine head 8 to move along the length direction of the row of corn stalks, and then the cutting assemblies 21 cut the corn stalks in sequence. Since the cutting assembly 21 includes the lifting unit 213, the height of the corn stalk cutting can be adjusted according to actual needs.

[0043] As shown in Figure 3 The lifting unit 213 includes a connecting frame 2131, a sliding rail 2132, a sliding block 2133, a connecting block 2135, and a hydraulic rod 2134. The sliding rail 2132 is arranged on the connecting frame 2131, the sliding block 2133 is slidingly connected to the sliding rail 2132, the connecting block 2135 is sleeved on the hydraulic rod 2134, and the connecting block 2135 is connected to one side of the sliding block 2133. The hydraulic rod 2134 drives the connecting block 2135 to move up and down, and the hydraulic rod 2134 drives the rotating power unit 212 to move up and down through the connecting block 2135, thereby driving the disc cutting knife 211 on the rotating power unit 212 to move up and down. It should be noted that when adjusting, the heights of the connecting blocks 2135 in the two groups of cutting assemblies 21 should be kept consistent to improve the reliability of the cutting assemblies 21.

[0044] As shown in Figure 2As shown, the gathering mechanism 3 comprises two sets of conveying assemblies 31 oppositely arranged, and both sets of conveying assemblies 31 are arranged on the connecting frame 1.

The first conveying units 311 in the two sets of conveying assemblies 31 oppositely form a V-shaped gathering structure, and the second conveying units 312 in the two sets of conveying assemblies 31 oppositely and parallelly arranged.

[0045] As shown in the drawings, Figure 2 The first conveying unit 311 and the second conveying unit 312 are the same structure, the first conveying unit 311 comprises a belt frame 3111, a first driving roller 3112, a first driven roller 3113 and a first conveying belt 3114, the belt frame 3111 is vertically connected to the connecting frame 1, the first driving roller 3112 and the first driven roller 3113 are both vertically connected to the belt frame 3111 and rotationally connected with the belt frame 3111, and the first conveying belt 3114 is sleeved on the first driving roller 3112 and the first driven roller 3113.

[0046] When the cutting assembly 21 cuts a corn stalk, the corn stalk falls into the groove formed by the two sets of conveying assemblies 31, and when a certain amount of corn stalks are poured, the conveying directions of the two sets of conveying assemblies 31 are opposite, the conveying directions of the first conveying unit 311 and the second conveying unit 312 in each set of conveying assembly are the same, and then a certain amount of corn stalks are advanced to the conveying mechanism 4. It should be pointed out that the distance from the cutting mechanism 2 to the bundling mechanism 5 is greater than the length of the corn stalk, so as to avoid that the corn stalk falls without entering the bundling mechanism 5.

[0047] As shown in the drawings, Figure 2 The conveying mechanism 4 comprises a second driving roller 41, a second driven roller 42 and a second conveying belt 43, the second driving roller 41 and the second driven roller 42 are both arranged on the connecting frame 1 through a connecting column 44, the second driving roller 41 and the second driven roller 42 are parallelly arranged and the axis of the second driving roller 41 is parallel to the connecting frame 1, and the second conveying belt 43 is sleeved on the second driving roller 41 and the second driven roller 42. When the conveying mechanism 4 works, the second driving roller 41 and the second driven roller 42 rotate clockwise, and then drive the second conveying belt 43 on them to rotate clockwise, so as to convey the corn stalks to the bundling mechanism 5.

[0048] In order to avoid that the corn stalks enter the two sides of the bundling mechanism 5, the harvesting and bundling device further comprises a limiting mechanism 7. As shown in the drawings, Figure 2As shown, the limiting mechanism 7 includes two sets of symmetrically arranged limiting assemblies 71, each of which includes a limiting plate 711 and a support frame 712 connected thereto, the limiting plate 711 is arranged on the connecting frame 1 through the support frame 712 and is located above the second conveying belt 43, and the limiting plates 711 of the two sets of limiting assemblies 71 are oppositely and obliquely arranged to limit the corn stalks on the second conveying belt 43.

[0049] As shown in Figures 3-6 The bundling mechanism 5 includes a ring-shaped driving assembly 51, a winding seat 52, and a cutting assembly 53, the ring-shaped driving assembly 51 includes a ring-shaped connecting seat 511, a first gear 512, a second gear 513, and a plurality of support rollers 514, the ring-shaped connecting seat 511 is arranged on the connecting frame 1, the plurality of support rollers 514 are arranged on one end face of the ring-shaped connecting seat 511 and are spaced apart, a receiving through hole is formed in the middle part of the first gear 512, the first gear 512 is coaxially arranged with the ring-shaped connecting seat 511, and a ring-shaped abutting portion 515 on the first gear 512 abuts on the roller surface of the support roller 514, the winding seat 52 is connected with the first gear 512, the second gear 513 is arranged on the ring-shaped connecting seat 511 and is engaged with the first gear 512, and the second gear 513 rotates to drive the winding seat 52 on the first gear 512 to rotate.

[0050] As shown in Figure 4 and Figure 5 The cutting assembly 53 includes a mounting seat 531, a line hooking unit 532, and a line cutting unit 533, the line hooking unit 532 and the line cutting unit 533 are arranged on the other end face of the ring-shaped connecting seat 511 through the mounting seat 531, the conveying mechanism 4 conveys the corn stalks to the receiving through hole of the first gear 512, the second gear 513 rotates to drive the winding seat 52 on the first gear 512 to rotate, thereby making the line on the winding seat 52 bundle the corn stalks, when the bundling is completed, the line hooking unit 532 is used to hook and pull the line wound on the winding seat 52, the line cutting unit 533 is used to cut the line segment between the hooking and pulling position and the outer winding position of the stalk, and the cut end of the line at the hooking position is clamped in the inside of the line hooking unit 532. As shown in Figure 4As shown, the cutting assembly 21 is in an initial state, and the hooking unit 532 and the cutting unit are not extended. The cutting unit 533 is connected with a cutting cylinder 5331 and a cutting knife 5332, and the hooking unit 532 is connected with a hooking cylinder 5321 and a hooking column 5322. The winding seat 52 is wound with a certain adhesive line. When the corn stalks in the first gear 512 are needed to be bundled, the end of the line hanging in the air on the winding seat 52 is adhered to the corn stalks with the rotation of the winding seat 52, and the winding seat 52 continues to rotate to bundle the corn stalks. When the bundling is about to end, the winding seat 52 moves to the side away from the mounting seat 531 in the cutting assembly 21, and the hooking cylinder 5321 and the cutting cylinder 5331 drive the hooking column 5322 and the cutting knife 5332 to extend, respectively. When the winding seat 52 continues to move to the upper side of the cutting assembly 21 and close to the cutting assembly 21, the bundling line is wound on the outside of the stalk and the outer side of the rod-shaped structure of the cylinder extension at this time. Then the hooking cylinder 5321 and the cutting cylinder 5331 drive the hooking column 5322 and the cutting knife 5332 to retract, respectively. The hooking column 5322 hooks the line, and the line is a certain distance away from the cutting edge of the cutting knife 5332 at this time. When the hooking column 5322 retracts into the hole of the hooking cylinder 5321, due to the distance difference between the hooking column 5322 and the cutting knife 5332, the hooking column 5322 and the annular sleeve clamp the two ends of the line between the annular sleeve and the hooking column 5322, and then the cutting knife 5332 continues to retract to generate a displacement difference away from the annular sleeve to cut the line.

[0051] As shown in Figure 2 The righting mechanism 6 includes two oppositely arranged righting assemblies 61, and each righting assembly 61 includes a support plate 611 arranged on the connecting frame 1 and rotationally connected with the connecting frame 1, and a righting door 612 rotationally connected with the support plate 611.

[0053] When the bundling mechanism 5 is working, the first rotating unit 613 drives the supporting plate 611 to rotate, so that the supporting plate 611 is parallel to the connecting frame 1. When the bundling mechanism 5 finishes bundling the corn stalks, the conveying mechanism 4 continues to move to convey the bundled corn stalks to the righting mechanism 6 until the top end of the corn stalks is separated from the conveying mechanism 4, and the corn stalks are located on the righting door 612. At this time, the first rotating unit 613 drives the supporting plate 611 to rotate, so that the supporting plate 611 forms a certain angle with the connecting frame 1, and then the top end of the corn stalks falls from the gap between the righting door 612 and the conveying mechanism 4 to the field. After that, the second rotating unit 614 drives the righting door 612 to open upward to right the inclined corn stalks. After being righted, the harvesting and bundling device continues to move forward, and the righting door 612 is separated from the bundled corn stalks, thereby completing the harvesting work of the corn stalks.
