Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, and more specifically to a side-exit leek harvesting and baling machine. Background Technology

[0002] Currently, leek harvesters on the market do not have a baling function. They can only harvest the leeks and place them on the ground, requiring manual picking and baling. The efficiency of mechanized harvesting is not realized. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide a side-exit leek harvesting and bundling integrated machine.

[0004] According to the present invention, a side-exit leek harvesting and baling integrated machine is provided, comprising: a harvester, a conveyor belt, a support frame, a side-exit clamping mechanism, a handrail for operator to control forward movement, a baling machine disposed on one lateral side of the support frame, a flipping mechanism disposed on the downstream side of the conveyor belt, and a leek receiving arm mounted on the support frame. The side-exit clamping mechanism includes: a gripper support system beam connected to the support frame; a lead screw and a rectangular connecting rod extending obliquely on the gripper support system beam relative to the upper surface of the conveyor belt or the leek receiving arm; a threaded sleeve and a rectangular sleeve respectively movably sleeved on the lead screw and the rectangular connecting rod; and a connecting rod connected to the lead screw and the rectangular connecting rod. The rotating mechanism includes: a baffle mounted on the bracket; a bucket having a straight plate body and a curved plate formed on the upstream side of the straight plate body; a sleeve welded to the bottom of the straight plate body; a guide post coupled to the sleeve in a gear shape; a motor II driving the guide post to rotate; a weight sensor provided on the bracket at a position corresponding to the position below the straight plate body on the upstream side of the guide post; and the initial clamping position of the gripper arm being formed in the space between two spaced-apart curved arms.

[0005] Preferably, three gripper arms are installed at the end of the connecting rod via gripper receiving column, two of which are gripper arms I fixedly welded to both ends of the gripper receiving column, and a guide square hole is provided in the middle part of the gripper receiving column, through which gripper arm II is movably installed.

[0006] Preferably, the leading edge of the lowest side of the gripper arm I and gripper arm II is at the initial gripping position lower than the corresponding position of the chive-receiving curved arm on both sides by a predetermined value.

[0007] Preferably, the arm body of the gripper arm II is equipped with a lever and a positioning sleeve across the gripper receiving column. The positioning sleeve serves as a positioning part to prevent the arm body from passing through the gripper receiving column, and the lever is used to move the arm body located on the opposite side of the guide square hole closer to or further away from the leek receiving curved arm, thereby forming a closed-loop structure for gripping leeks or an open-loop structure for receiving leeks together with the gripper arms I on both sides.

[0008] Preferably, the leek-shaped support arm is a long, cantilevered curved plate with the fixed end welded to a connecting plate, which is then fixedly welded to a bracket; the free end extends obliquely upwards towards the downstream side.

[0009] Preferably, the tipping bucket is installed on the support above the upstream part of the leek receiving curved arm.

[0010] Preferably, the sleeve is configured as a vertical tooth cylinder and the guide post is configured as a vertical tooth cylinder.

[0011] Preferably, the bent plate is formed as an arc-shaped structure with a constant radius centered on the fixed connection between the straight plate body and the sleeve.

[0012] Preferably, the conveyor belt is arranged horizontally, or it is arranged at an angle with the support to form a suspension system.

[0013] Preferably, the tipping bucket is additionally provided with a metering fork device with a fork.

[0014] The side-exit leek harvesting and baling machine of the present invention can effectively improve work efficiency and reduce labor intensity. It can operate in a semi-automatic mode, which can quickly measure and bale the leeks, and also allows the operator to respond promptly to work scenarios that require manual intervention.

Detailed Implementation

[0022] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The exemplary embodiments described below and illustrated in the drawings are intended to teach the principles of the invention, enabling those skilled in the art to implement and use the invention in various environments and for various applications. Therefore, the scope of protection of the present invention is defined by the appended claims, and the exemplary embodiments are not intended, and should not be considered, a limiting description of the scope of protection of the present invention. Furthermore, for ease of description, the same elements in the drawings are indicated by the same or similar reference numerals, and the dimensions of the various parts shown are not necessarily drawn to actual scale. Regarding orientational descriptions, such as the front corresponding to the forward direction of the all-in-one machine, and the orientations or positional relationships indicated by up, down, left, right, top, bottom, etc., are all based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. The following description of the various embodiments emphasizes the differences between the various embodiments, and their similarities or commonalities can be referred to mutually. For the sake of brevity, they will not be described in detail. The technical features of the different embodiments can be freely combined to form more embodiments according to design needs.

[0023] The following example illustrates the side-exit leek harvesting and baling machine according to the present invention, using a small, hand-push harvester as an example. Figures 1-6 As shown, the main components include: a harvester 01, a conveyor belt 02, a bracket 03 with wheels mounted on the bottom, a side-mounted clamping mechanism including a crossbeam 04 with a gripper support system, a handrail 06 for the operator to control forward movement, a strapping machine 07 located on one side of the bracket 03, and a tipping bucket 08 (tilting mechanism) located on the downstream side of the conveyor belt 02.

[0024] During operation, the harvester 01 located at the front uses a cutter (not shown) to harvest the chives gathered by, for example, the front-end lifting device (not shown). The chives are output from the rear chive output port 0102 to a conveyor belt 02, such as a sponge belt. Guided by the belt guide rollers I 0201 and II 0203, which are set apart, the chives are conveyed to the rear tipping bucket 08 for weighing. The side-out clamping mechanism clamps and outputs the chives to the side, that is, to the tying machine 07 for tying. This will be described in more detail later.

[0025] Figure 2 The working principle of the side-out clamping mechanism is shown. The side-out clamping mechanism is used to clamp the chives from the upstream conveyor belt 02 and send them to the lateral side of the integrated machine. It includes: the above-mentioned jaw support system beam 04 connected to the bracket 03; a lead screw 0401 and a rectangular connecting rod 0409 extending obliquely on the jaw support system beam 04 relative to the upper surface of the conveyor belt 02 or the chive receiving arm 0801 described later; a threaded sleeve 0402 and a rectangular sleeve 0405 respectively movably sleeved on the lead screw 0401 and the rectangular connecting rod 0409; a connecting post 0404 connecting the threaded sleeve 0402 and the rectangular sleeve 0405; and a connecting rod 0406 connected to the rectangular sleeve 0405. At the end of the generally L-shaped connecting rod 0406, three jaw arms are installed via the jaw receiving column 0407, as described later. The electric motor I0403 drives the lead screw 0401, which causes the threaded sleeve 0402, the connecting column 0404, and the rectangular sleeve 0405 to move as a whole, thereby driving the gripper arm to complete the lifting and side-extraction of the chives.

[0026] The gripper support column 0407 extends laterally along the integrated machine. Gripper arms I 0408 are fixedly welded to both ends. A guide square hole 0412 is provided in the middle, through which gripper arm II 0410 is movably installed.

[0027] More specifically, gripper arms I 0408 and II 0410 are arranged side-by-side on the gripper receiving column 0407, spaced apart by arc-shaped plates. This ensures that the leading edge of the lowest gripper arm is at the initial gripping position lower than the corresponding positions of the chive receiving curved arms 0801 on both sides (described later) by a predetermined value, thereby enabling more reliable gripping of the chives. This predetermined value is set so as not to cause interference between the gripper arms and the chive receiving curved arms 0801 passing by as they move upward toward the strapping machine 07.

[0028] For example Figure 3 , 4As shown, a lever 0411 and a positioning sleeve 0422 are mounted on the arm body of the gripper arm II 0410, with the gripper receiving crossbar 0407 as a secondary component. The arm body passes through the guide square hole 0412 of the gripper receiving crossbar 0407, thus forming a movable arm that can be moved relative to the guide square hole 0412. The positioning sleeve 0422 serves as a positioning part to prevent the arm body from passing through the gripper receiving crossbar 0407. After the lever 0411 is moved upwards, the arm body on the opposite side of the guide square hole 0412 moves downwards towards the leek-receiving curved arm 0801, thus forming a closed-loop structure for gripping the leek together with the gripper arms I 0408 on both sides. Conversely, after the lever 0411 is moved downwards, the positioning sleeve 0422 on the arm body rises until it contacts the gripper receiving crossbar 0407, acting as a limit. At this point, the lower edge of the arm body moves away from the leek-receiving curved arm 0801 until it is approximately at the same height as the lower edge of the baffle 0802, forming an open ring structure for receiving leeks, allowing leeks from the upstream side to enter the clamping station.

[0029] like Figures 2-5 As shown, the leek-supporting curved arm 0801 is configured as a long, cantilevered curved plate, with its fixed end welded to a connecting plate 0805, which is fixedly welded to the bracket 03; the free end extends obliquely upwards towards the downstream side. The space between the two spaced-apart leek-supporting curved arms 0801 forms the initial clamping position of the aforementioned gripper arm.

[0030] Above the upstream side of the leek-supporting curved arm 0801, a flipping mechanism is installed horizontally on the bracket 03, such as... Figure 6 As shown, the device includes: a baffle 0802 vertically mounted on a bracket 03; a tipping bucket 08 having a straight plate body 0810 and a curved plate 0808 formed on the upstream end side of the straight plate body 0810; a sleeve, for example, in the form of a vertical toothed cylinder 0804, welded to the underside of the straight plate body 0810; a guide post, for example, in the form of a vertical toothed cylinder 0806, coupled to the sleeve via a vertical gear; and a motor II 0807 that drives the guide post to rotate. Thus, the motor II 0807 can drive the sleeve to rotate back and forth, thereby manipulating the tipping bucket 08 to tilt by a predetermined angle.

[0031] Among them, the curved plate 0808 is formed as an arc-shaped structure with the fixed connection part between the straight plate body 0810 and the sleeve as the center. Therefore, it can be positioned at the initial horizontal position of the tipping bucket 08 corresponding to the upstream belt guide roller II0203 (corresponding to Figure 6 The radius r1 shown is the same as the flip limit position (corresponding to...). Figure 6 The radii r2 and r1 (r2) shown in the diagram are all constant radii of the same size, thus maintaining a constant close proximity to the conveyor belt 02 at the upstream belt guide roller Ⅱ0203.

[0032] In the initial state before the tipping bucket 08 is flipped, a horizontal trough with an upward opening can be formed by the baffle 0802 located on the downstream side and the straight plate body 0810 and curved plate 0808 located on the upstream side, which is used to receive the chives falling from the upstream conveyor belt 02.

[0033] When the tipping bucket 08 flips, as Figure 6 As shown, the edge of the curved plate 0808 rises, just enough to block the chives on the conveyor belt 02 from continuing to enter the tipping bucket 08. At the same time, on the downstream side, an open gap is created between the straight plate body 0810 and the baffle 0802, allowing the chives to fall onto the chive receiving curved arm 0801 from there.

[0034] After the tipping bucket 08 completes its unloading, it flips back to the horizontal trough state. The upper edge of the curved plate 0808 is flush with the upstream conveyor belt 02, allowing the chives to start falling into the horizontal trough again.

[0035] like Figure 4 As shown, a weight sensor 0803 is installed below the straight plate body 0810 on the upstream side of the support 03, corresponding to the guide column. Thus, after the chives conveyed from the upstream conveyor belt 02 to the tipping bucket 08 reach the preset weight, the motor II 0807 starts and directly drives the tipping bucket 08 to flip, so that the chives first fall onto the chive receiving curved arm 0801, and then enter the recessed space of the gripper arms I 0408 on both sides, where the gripper arms II 0410 form a closed loop clamping.

[0036] After the gripper arm holds the chives and moves them to the side, they are placed into the bundling machine 07. After the bundling and packaging are completed, manually push the lever 0411 to create a release gap from the original closed-loop structure, allowing the gripped chives to fall out of the gap and directly into the collection basket (not shown) on the ground or below.

[0037] The above example shows a tipping bucket 08 with a curved plate 0808, but it is not limited to this. A metering fork device (time adjustable) with a fork can also be used as an additional or alternative measure to complete the predetermined amount of bundling measurement.

[0038] Figure 1 The harvester 01 and baler 07 shown schematically can be equipped with known corresponding devices. For example, the conveyor belt 02 is not limited to being horizontally set, but can also be arranged at an angle with the support 03 to form a front suspension system for a walking device such as a tractor, which will not be described in detail here.

[0039] Thus, the side-exit leek harvester and baler can include: a leek cutting device, a lifting device, a rotating baling device, and a side-exit holding device. With manual operation and support, this side-exit leek harvester can harvest leeks at a stable speed. The leeks are cut by the cutting action of the leek cutting device.

[0040] In the description of this application, "a plurality of" means two or more, unless otherwise expressly specified. Unless otherwise expressly specified and limited, the terms "installed," "connected," "linked," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Although the invention has been described with reference to various specific embodiments, it should be understood that modifications can be made within the spirit and scope of the described inventive concept. Therefore, it is intended that the invention be limited to the described embodiments but will have the full scope defined by the language of the appended claims.
