Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of agricultural production, and particularly relates to a leek bundling harvester and a working method thereof. BACKGROUND

[0002] In modern agricultural production, leek, as a widely planted vegetable crop, has long been faced with the problem that efficiency and quality are difficult to be balanced in the harvesting link. Traditional manual harvesting of leek requires a large amount of manpower and time, and has high labor intensity, which is difficult to meet the demand of large-scale planting. With the advancement of agricultural mechanization, most of the leek harvesters on the market adopt the mode of cutting first and collecting later. This harvesting mode has many problems in actual operation. The leek plant is long and soft, and the cutting first and collecting later mode is easy to cause the leek to scatter on the ground, entangle with each other, cause leaf damage, and affect the product quality and appearance. At the same time, subsequent manual sorting, arranging and bundling are required, which has high labor cost and long operation time. In addition, with the continuous rise of labor cost and the increasingly prominent problem of shortage of agricultural labor, the traditional harvesting mode has been difficult to adapt to the requirements of efficient and intensive development of modern agriculture. Therefore, developing a new type of harvesting equipment capable of realizing efficient harvesting of leek, reducing loss and reducing manual intervention has become the key to solving the current leek harvesting problem.

[0044] The belt reel is placed in the belt placing box, and the outer end of the belt is inserted into the belt conveying groove from the opening and located at one end of the belt conveying groove close to the hook blade rod 5.2.6; the two crawler walking mechanisms drive the rack 1 to move to the field, so that a row of leek ridge is located between the two conical rods 3.1; then the controller controls the relative sides of the two conical rods 3.1 to rotate upward, and the belt conveying mechanism two 4.2 and the belt conveying mechanism one 4.1 work, and the driving member two drives the two disc cutters 5.3.2 to rotate relative to each other; then the two crawler walking mechanisms drive the rack 1 to advance, so that the leeks on the leek ridge enter between the two conical rods 3.1, and the two conical rods 3.1 collect and upright the leeks, when the rack 1 advances a preset distance or the limit switch installed on the fixed frame 5.1 detects the leeks, the controller controls the two crawler walking mechanisms to stop working, the bundling mechanism 5.2 of the harvesting and bundling device 5 performs bundling work on the leeks, and then the two crawler walking mechanisms drive the rack 1 to continue to move along the leek ridge, the two disc cutters 5.3.2 rotating relative to each other cut the bundled leeks, and the belts 4.1.3 of the two belt conveying mechanisms one 4.1 clamp the cut leeks; with the intermittent movement of the rack 1, the leeks on the leek ridge are continuously bundled by the bundling mechanism 5.2, cut by the two disc cutters 5.3.2 and conveyed to the conveying belt of the belt conveying mechanism two 4.2 by the two belt conveying mechanisms one 4.1, and the belt conveying mechanism two 4.2 conveys the leeks to the collecting box in sequence.

[0045] The process of the bundling mechanism 5.2 for bundling the leeks is as follows:

[0046] The controller controls the rotation motor to drive the rotation shaft to rotate, and the rotation shaft drives the two hinged shafts and the two cranks 5.2.5 to rotate through the two bevel gear pairs. The two cranks 5.2.5 drive the two translation plates 5.2.2 to first translate backward, then translate forward, and then translate backward to the original position through the two connecting rods 5.2.4.

[0047] As shown in FIG. 5.2.1, in the initial state, the two end portions of each V-shaped groove are aligned with the two end portions of the corresponding horizontal straight groove on the U-shaped groove, each moving rod 5.2.3 is located at the rear end position of the corresponding V-shaped groove and the rear end position of the corresponding horizontal straight groove, the keys on the lead screw one and the lead screw two are embedded in the key grooves of the corresponding circular gear 5.2.14, and the nut block one and the nut block two are respectively located at one end of the two thread segments away from each other. Figure 10 When the two translation plates 5.2.2 start to translate backward from the initial state, due to the restriction of the V-shaped grooves and the U-shaped grooves, the two moving rods 5.2.3 move towards each other along the rear inclined grooves of the corresponding V-shaped grooves and the rear vertical straight grooves of the corresponding U-shaped grooves, thereby driving the hook blade rod 5.2.6 and the pinning rod 5.2.7 to move towards each other, causing the keys on the lead screw one and the lead screw two to disengage from the key grooves of the corresponding circular gear 5.2.14, and simultaneously the hook blade rod 5.2.6 drives the hook blade rods 5.2.18 to move synchronously through the lead screw one and the nut block one, causing the sliding rods to move along the sliding grooves on the hook blade rods 5.2.18, and pulling the hook blade rods 5.2.18 to rotate towards the pinning rod 5.2.7. Figure 11 As shown in FIG. 5.2.2, when the two moving rods 5.2.3 move to the turning position of the corresponding V-shaped groove and the end position of the rear vertical straight groove of the corresponding U-shaped groove away from the horizontal straight groove, the cutting edge one on the pinning rod 5.2.7 is embedded in the groove, and the two hook blades on the hook blade rods 5.2.18 pierce into the outer end of the bandage.

[0048] Then, as the two translation plates 5.2.2 continue to translate backward, the two moving rods 5.2.3 move away from each other along the front inclined grooves of the corresponding V-shaped grooves and the rear vertical straight grooves of the corresponding U-shaped grooves, thereby driving the hook blade rod 5.2.6 and the pinning rod 5.2.7 to move away from each other. The hook blade rod 5.2.6 drives the hook blade rods 5.2.18 to move synchronously through the lead screw one and the nut block one, causing the sliding rods to move along the sliding grooves, thereby pushing the hook blade rods 5.2.18 to rotate away from the pinning rod 5.2.7. The two hook blades hook the outer end of the bandage and pull out part of the bandage in the conveying groove, releasing part of the bandage from the bandage roll. Figure 12As shown, when the two moving rods 5.2.3 move to the upper end position of the corresponding V-shaped groove and the lower end position of the corresponding horizontal straight groove, the crank 5.2.5 overlaps with the corresponding connecting rod 5.2.4, the spline is embedded in the corresponding spline groove, the upper limit magnet two 5.2.10 on each translation plate 5.2.2 is aligned with the lower limit magnet one 5.2.9 on the corresponding support frame 5.2.1, the lower limit magnet one 5.2.9 on each support frame 5.2.1 moves upward under the action of magnetic force, passes through the corresponding vertical straight groove, and is attracted together with the upper limit magnet two 5.2.10 on the corresponding translation plate 5.2.2, so that the end of the lower vertical straight groove of the U-shaped groove close to the horizontal straight groove is blocked, and the corresponding spring one is stretched.

[0049] Then each translation plate 5.2.2 changes from backward translation to forward movement, because the end of the lower vertical straight groove of the U-shaped groove close to the horizontal straight groove is blocked, the moving rod 5.2.3 cannot move along the lower vertical straight groove of the corresponding U-shaped groove, each translation plate 5.2.2 drives each moving rod 5.2.3 to move forward along the corresponding horizontal straight groove, thereby driving the hook knife rod member 5.2.6 and the pinning rod member 5.2.7 to move forward synchronously, the lower limit magnet one 5.2.9 on each support frame 5.2.1 is disconnected from the upper limit magnet two 5.2.10 on the corresponding translation plate 5.2.2, and moves downward to the original position under the action of the restoring force of the corresponding spring one, the hook knife rod member 5.2.6 and the pinning rod member 5.2.7 drive each cogwheel 5.2.14 to mesh with the corresponding rack 5.2.11 through the screw rod one and the screw rod two, thereby driving the screw rod one and the screw rod two to rotate forward, the screw rod one drives the two hook knife rods 5.2.18 to move away from the pinning rod member 5.2.7 through the nut block one, so that the sliding rod moves along the sliding groove on each hook knife rod 5.2.18, thereby pushing the hook knife rod 5.2.18 to continue to rotate away from the pinning rod member 5.2.7, the screw rod two drives the pin pressing plate 5.2.15 to push a row of pins to move along the pin pressing groove towards the hook knife rod member 5.2.6 through the nut block two, at the same time, as the hook knife rod member 5.2.6 and the pinning rod member 5.2.7 move forward, the band between the hook knife rod member 5.2.6 and the pinning rod member 5.2.7 contacts the two clamping plates 5.2.8, due to the blocking action of each clamping plate 5.2.8, the two hooks continue to pull out the band from the belt conveying groove, and the band between the hook knife rod member 5.2.6 and the pinning rod member 5.2.7 wraps one side of part of the leek; as Figure 13 As shown, when each moving rod 5.2.3 moves to the upper end position of the corresponding V-shaped groove and the lower end position of the corresponding horizontal straight groove, the pins are pushed to the end position of the pin pressing groove close to the hook knife rod member 5.2.6 by the pin pressing plate 5.2.15, and the band between the hook knife rod member 5.2.6 and the pinning rod member 5.2.7 wraps one side of part of the leek.

[0050] With the continuous forward movement of each translation plate 5.2.2, due to the restriction of each V-shaped groove and each U-shaped groove, the two moving rods 5.2.3 move towards each other along the upper inclined groove of the corresponding V-shaped groove and the upper vertical groove of the corresponding U-shaped groove, thereby driving the hook blade rod 5.2.6 and the pinning rod 5.2.7 to move towards each other, so that the spline is separated from the corresponding spline groove, and the hook blade rod 5.2.6 moves synchronously with each hook blade rod 5.2.18 through the screw rod one and the nut block one, so that the sliding rod moves along the sliding groove, and each hook blade rod 5.2.18 is rotated towards the pinning rod 5.2.7, thereby driving the outer end of the bandage to rotate towards the pinning rod 5.2.7, and with the movement of the hook blade rod 5.2.6 and the pinning rod 5.2.7 towards each other, the bandage between the hook blade rod 5.2.6 and the pinning rod 5.2.7 wraps the other side of the leeks, and each clamping plate 5.2.8 is rotated forward, and each tension spring one is stretched; as shown in Figure 14 When the moving rod 5.2.3 moves to the turning position of the corresponding V-shaped groove and the end position of the vertical groove away from the horizontal groove of the corresponding U-shaped groove, the bandage between the hook blade rod 5.2.6 and the pinning rod 5.2.7 is separated from the clamping plate 5.2.8, and the bandage completely wraps the leeks, the clamping plate 5.2.8 is rotated back to the original position under the restoring force of the corresponding tension spring one, the two ends of the row of nails at the end position of the pressing nail groove close to the hook blade rod 5.2.6 are inserted into the two ends of the bandage between the hook blade rod 5.2.6 and the pinning rod 5.2.7, and are bent under the limiting action of the inverted trapezoidal groove of the hook blade rod 5.2.6, thereby fixing the two ends of the bandage between the hook blade rod 5.2.6 and the pinning rod 5.2.7, and the cutting edge between the pressing nail groove and the belt conveying groove cuts the bandage between the hook blade rod 5.2.6 and the pinning rod 5.2.7, thereby completing the bundling work of the leeks, and each cutting edge two is embedded in the through groove of the corresponding hook blade, cutting the bandage on the corresponding hook blade, so that the remaining bandage on the two hook blades falls to the ground, avoiding the part of the bandage cut by the cutting edge remaining on the two hook blades, affecting the subsequent bundling work.

[0051] With the continuous forward movement of each translation plate 5.2.2, the two moving rods 5.2.3 move away from each other along the rear inclined groove of the corresponding V-shaped groove and the upper vertical groove of the corresponding U-shaped groove, thereby driving the hook blade rod 5.2.6 and the pinning rod 5.2.7 to move away from each other, and the hook blade rod 5.2.6 moves synchronously with each hook blade rod 5.2.18 through the screw rod one and the nut block one, so that the sliding rod moves along the sliding groove of each hook blade rod 5.2.18, thereby pushing the hook blade rod 5.2.18 to rotate away from the pinning rod 5.2.7; as shown in Figure 15As shown, when the two moving rods 5.2.3 move to the rear end positions of the corresponding V-shaped grooves and the front end positions of the vertical grooves of the corresponding U-shaped grooves, the crank 5.2.5 is arranged in line with the connecting rod 5.2.4, the spline is embedded in the corresponding spline groove, the rear limiting magnet two 5.2.10 on each translation plate 5.2.2 is aligned with the front limiting magnet one 5.2.9 on the corresponding support frame 5.2.1, the front limiting magnet one 5.2.9 on each support frame 5.2.1 moves upward under the action of magnetic force, passes through the front vertical groove of the corresponding U-shaped groove, and is attracted together with the rear limiting magnet two 5.2.10 on the corresponding translation plate 5.2.2, so that the end of the front vertical groove of the corresponding U-shaped groove close to the horizontal groove is blocked, and the corresponding spring one is stretched.

[0052] Then each translation plate 5.2.2 changes from forward movement to backward movement, because the end of the front vertical groove of the corresponding U-shaped groove close to the horizontal groove is blocked, the moving rod 5.2.3 cannot move along the front vertical groove of the corresponding U-shaped groove, each translation plate 5.2.2 drives the moving rod 5.2.3 to move backward along the corresponding horizontal groove, thereby driving the hooking and cutting rod member 5.2.6 and the pinning rod member 5.2.7 to move backward synchronously, the front limiting magnet one 5.2.9 on each support frame 5.2.1 is disconnected from the rear limiting magnet two 5.2.10 on the corresponding translation plate 5.2.2, and moves downward to the original position under the action of the restoring force of the corresponding spring one, the hooking and cutting rod member 5.2.6 and the pinning rod member 5.2.7 drive the circular gear 5.2.14 to mesh with the corresponding rack 5.2.11 through the screw rod one and the screw rod two, thereby driving the screw rod one and the screw rod two to reverse, the screw rod one drives the two hooking and cutting rods 5.2.18 to move toward the pinning rod member 5.2.7 through the nut block one, so that the sliding rod moves along the sliding groove on each hooking and cutting rod 5.2.18, thereby driving the hooking and cutting rod 5.2.18 to rotate toward the pinning rod member 5.2.7, the screw rod two drives the pressing nail plate 5.2.15 to move away from the hooking and cutting rod member 5.2.6 along the pressing nail groove through the nut block two, so that the nail releasing groove communicates with the pressing nail groove, the spring two drives the pushing nail plate to drive each row of nails to slide along the nail releasing groove toward the pressing nail groove, so that one row of nails is pushed into the pressing nail groove, until each moving rod 5.2.3 is located at the rear end position of the corresponding V-shaped groove and the rear end position of the corresponding horizontal groove, and returns to the original position.
