For example, two steps can be swapped or performed in parallel.

[0025] The utility model provides a leek harvester. Fig. 9 As shown, the leeks gathered by the front straw supporter are harvested by a cutting knife (not shown) at the front, and the leeks are conveyed to the leek weigher 0402 at the rear by a conveyor belt 0403 arranged on the conveyor frame 04 for weighing and stacking. The leeks are clamped by the automatic leek clamping device (hereinafter also referred to as the device) according to the utility model, and transferred to two separated and parallel conveyor belts B0502 on the bundling frame 05, and then transported to the bundling machine (not shown) for bundling. Among them, the clamping claw system 03 of the device moves back and forth between the conveyor frame 04 and the bundling frame 05 via the crossbeam 01 bridged between the crossbeam A0401 and the crossbeam B0501, so as to grasp and hand over the leeks.

[0026] like Figure 1 As shown, the device includes: a beam 01, a clamping sleeve 02 that can move back and forth laterally relative to the beam 01 (such as between positions A and B in the figure), and a clamping jaw system 03 that can be moved up and down on the clamping sleeve 02.

[0027] Among them, a beam rack 0101 is provided on the side of the beam 01, and a motor A0202 is fixed on the sleeve 02 which is mounted on the beam 01 through a rectangular hole A0201. The motor A0202 is meshed with the beam rack 0101 via a driving gear 0210, thereby driving the sleeve 02 to move back and forth along the beam 01.

[0028] like Figure 2 , 3 As shown, a horizontally extending suspension plate 0203 is also fixedly provided on the clamping sleeve 02, on which are provided: a base support hole 0206 and a support plate 0204 for installing and guiding the clamping system 03, respectively, and a motor F0220 for driving the clamping system 03.

[0029] In this way, Figure 4 The base of the clamping system 03 shown is installed in the base support hole 0206, and the motor F0220 adjacent to the base support hole 0206 is used to drive the clamping part below the clamping system 03 to open and close.

[0030] like Figures 4 to 8 As shown, the clamping system 03 as a whole comprises: a rack base plate 0310 with a fixed clamping plate 031001 at the front end, and a rack movable plate 0301 connected to a movable clamping jaw 0306 at the front end via a connecting rod 0305, which is used to slidably mount the rack movable plate 0301 on a support plate 0304 of the rack base plate 0310.

[0031] A rack F0311 is provided on the rack base plate 0310, and skirt plates 0309 for guiding cooperation are provided on both sides of the rack F0311 in the horizontal direction. Support plates 0304 are welded on the rack base plate 0310 on both sides of the rack F0311 in the vertical direction, wherein the upper end side of the rack F0311 is separated from the adjacent support plates 0304 by a predetermined distance (configured as a toothless section). Rectangular holes B0319 are provided at corresponding positions on each support plate 0304. A rack movable plate 0301 is installed through the rectangular holes B0319 in parallel with the rack base plate 0310.

[0032] A rack G0302 is arranged on the upper side of the rack movable plate 0301, and a driving gear F0303 is installed between the rack base plate 0310 and the rack movable plate 0301 for engaging the rack F0311 and / or the rack G0302. In this way, the rack movable plate 0301 can move parallel to the rack base plate 0310 through the driving gear F0303 driven by the motor F0220.

[0033] A joint slot Ⅰ0323 is provided at the front of the rack movable plate 0301, and a group of round holes F0315 are provided on the joint slot Ⅰ0323. There is a round hole H030502 at each end of the connecting rod 0305, and the cylinder E0313 passes through the round hole H030502 at one end of the connecting rod 0305 and the round hole F0315 on the joint slot Ⅰ0323, and the axial position of the cylinder E0313 is fixed by a circlip, so that the connecting rod 0305 and the joint slot Ⅰ0323 are connected, so that the connecting rod 0305 and the rack movable plate 0301 can be connected.

[0034] More specifically, if Figure 7 , 8 As shown, the connecting rod 0305 is divided into two sections, and the two opposite sections are connected together by a spring 030503 (welded or connected by threaded hooks). A rectangular sleeve 030501 is sleeved on the outside of the connecting rod 0305, and one side of the rectangular sleeve 030501 is fixed to one section of the connecting rod 0305 by bolts, so that the rectangular sleeve 030501 can be used to guide the two parts of the connecting rod 0305 to make linear motion under the action of the spring 030503.

[0035] The front end (lower end) of the rack base plate 0310 is integrally fixed with a fixed jaw plate 031001 of a curved configuration, and the movable jaw 0306 arranged opposite to it is hinged to the support plate F0307 with the connecting rod 0305. The fixed jaw plate 031001, the movable jaw 0306 and the support plate F0307 form a ring-shaped gripping and accommodating space with a front end opening that can be expanded and contracted. The opposing surfaces of the fixed jaw plate 031001 and the movable jaw 0306 can be set as a rough plane to enhance the gripping force.

[0036] There is a rounded transition between the front end body and the rear end of the movable clamping jaw 0306, and a joint groove II 0318 is provided at the rear end. A round hole D0316 and a round hole E0317 are opened on the joint groove II 0318.

[0037] One end of the two support plates F0307 is fixed to both sides of the rack base plate 0310 by bolts F0308, and a circular hole D0316 is opened on the other end. The joint groove II0318 at the rear end of the movable clamp 0306 is pivotally connected to the circular hole D0316 of the support plate F0307 via the cylinder F0333, and the axial position of the cylinder F0333 is fixed by a retaining spring.

[0038] In the window surrounded by the cylinder F0333 and the joint groove II0318, the cylinder D0312 is fixed to the joint groove II0318 via the circular hole E0317, and the cylinder D0312 passes through the circular hole H030502 at the other end of the connecting rod 0305, and the axial position of the cylinder D0312 is fixed by a circlip. In this way, the connecting rod 0305 is connected to the movable clamping jaw 0306.

[0039] Therefore, by moving the rack movable plate 0301 forward and backward to push and pull the connecting rod 0305, the movable clamping jaw 0306 can be driven to pivot, thereby controlling the clamping and opening of the movable clamping jaw 0306 relative to the fixed clamping jaw plate 0310.

[0040] As mentioned above, the upper end of the rack base plate 0310 (i.e., the base away from the side of the movable clamping jaw 0306) can be installed in the base support hole 0206 in a lifting manner, wherein the support plate 0204 arranged flush with the side wall of the base support hole 0206 is a clamping structure with a relatively rectangular groove, which can clamp the skirt plate 0309 so that it can only move vertically along the support plate 0204. At this time, the support plate 0204 can guide one side of the rack base plate 0310 to slide up and down, and the driving gear F0303 connected to the rotating shaft of the motor F0220 extends into the space between the rack base plate 0310 and the rack movable plate 0301 to drive the rack base plate 0310 to move up and down, so that the rack base plate 0310 can be driven to adjust the opening and closing position of the movable clamping jaw 0306, and the rack movable plate 0301 can also be driven to adjust the tightness of the movable clamping jaw 0306 and further clamp it.

[0041] In the initial open state where the driving gear F0303 is simultaneously engaged with the rack F0311 and the rack G0302 and the movable jaw 0306 is away from the fixed jaw plate 031001, the starting motor F0220 drives the driving gear F0303 (for example Figure 4 In the middle, the rack base plate 0310 and the rack movable plate 0301 move downward for a distance (so that the fixed clamping claw plate 031001 reaches the side of the leek pile to be grasped). Since the driving gear F0303 is also engaged with the rack G0302 on the rack movable plate 0301, the rack movable plate 0301 moves backward in the opposite direction relative to the rack base plate 0310 (i.e., moves upward), and the rack movable plate 0301 pulls the connecting rod 0305 to move backward, and the connecting rod 0305 pulls the cylinder D0312 on the movable clamping claw 0306 to move backward. Since the cylinder F0333 on the movable clamping claw 0306 is fixed in the circular hole D0316 of the support plate F0307 and can only rotate, the movable clamping claw 0306 moves toward the fixed clamping claw plate 0310, thereby reaching the side of the leek pile to be grasped, completing the "grasping action" of the leek pile.

[0042] At this time, the rack F0311 on the rack base plate 0310 completes the engagement with the driving gear F0303, the clamping jaw system 03 stops moving downward, and the driving gear F0303 continues to rotate, and by engaging the rack G0302 on the rack movable plate 0301, the rack movable plate 0301 continues to move backward in the opposite direction relative to the rack base plate 0310. Since the connecting rod 0305 is split, the spring 030503 inside it continues to be stretched, so that the clamping jaw system 03 has a greater bite force on the leek pile, thereby realizing the "secondary clamping" action.

[0043] Then, when the starter motor F0220 is reversed (for example Figure 4 In the clockwise direction), the driving gear F0303 is only engaged with the rack G0302 on the rack movable plate 0301. At this time, the tension of the spring 030503 can be used to make the connecting rod 0305 as a whole still in a state of contraction, and the rack movable plate 0301 is still tightened upward. In this way, when the motor F0220 is started to reverse, the driving gear F0303 can smoothly engage the rack F0311 of the upper rack base plate 0310, and then the clamping system 03 moves upward for a certain distance, so that the leek pile clamped by the clamping system 03 is completely free from the interference of the leek weighing device 0402. In this process, since the spring 030503 is still in a stretched state, but the stretching force is a little smaller, the clamping system 03 is still in a "secondary clamping" state for the leek pile. At this time, the motor A0202 can be started to transport the leek pile gripped by the clamping system 03 to the bundling position of the baling machine.

[0044] Then, the starter motor F0220 is rotated (for example Figure 4 In the clockwise direction), as the motor F0220 further rotates clockwise, the spring 030503 returns to the relaxed state or even the compressed state, which will cause the connecting rod 0305 to push the cylinder D0312 on the movable clamp 0306 to move forward, so that the movable clamp 0306 pivots around the cylinder F0333 and opens, thereby realizing the state of relaxing the leek pile by the clamp system 03 and delivering it to the bundling position.

[0045] Then start the motor A0202 to reverse, driving the ferrule 02 to return to the initial gripping position along the beam 01.

[0046] In the description of the present application, the control system for controlling the actions of each component can be appropriately configured corresponding to the specific steps, which will not be repeated here. In addition, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. Unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Although the utility model has been described with reference to various specific embodiments, it should be understood that variations can be made within the spirit and scope of the utility model concept described. Therefore, it is intended that the utility model is not limited to the described embodiments, but will have the full scope defined by the language of the attached claims.
