Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a self-adjusting bean harvester. Background Art

[0002] The applicant disclosed a reaper including a divider in the patent application "A reaper for edible beans" with application number 202111576081.6. The divider is arranged at the end of the horizontal conveying assembly. The swing arm in the divider swings periodically to make different plants fall in different directions, so that the plants finally form the following shape: Figure 1 The cross-stacked effect shown is conducive to drying the fruits concentrated in the upper part of the plant, which is very suitable for cutting and drying bean plants. However, the cutting and drying machine still has some defects: 1. The swing arm in the above-mentioned prior art cutting and drying machine swings periodically with a fixed swing frequency. Figure 1 The ideal plant crossing effect shown in FIG. 1 requires that the plants in the horizontal conveying assembly be evenly spaced, which in turn requires that the plants planted in the land be evenly spaced, which is difficult to meet in practical applications; in actual operation, the spacing of the plants transported in the horizontal conveying assembly is random, which means that the posture of the plants that fall down after harvesting and drying is random, and it is difficult for all the plants in the lower layer and the upper layer to be evenly spaced. Figure 1 The results are shown as regular crossing, in some places the lower plants and the upper plants can cross, in some places the lower plants and the upper plants are parallel, which makes the actual technical effect of the reaper somewhat reduced; 2. The swing arm in the reaper of the above-mentioned prior art is installed on the shaft sleeve by threaded connection, but the reaper has very large vibration when working in the field, and the huge and continuous vibration makes the threaded connection of the swing arm easy to loosen. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the swing period of the swing arm of the prior art windrower is fixed, which affects the crossing effect of plants; on the other hand, the connection method of the swing arm of the prior art windrower is easy to loosen in a long-term vibration environment.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a self-adjusting bean harvester, comprising a frame, a grain dividing plate, a knife, a horizontal conveying assembly and a divider;

[0005] The crop separation plate is arranged in front of the frame, a star wheel is arranged on the crop separation plate, the cutter and the horizontal conveying assembly are both installed on the frame, and the cutter is located at the bottom of the frame; the frame, the crop separation plate, the star wheel, the cutter and the horizontal conveying assembly are consistent with the prior art;

[0006] The diverter is installed on the frame and located at the end of the horizontal conveying assembly. The diverter includes a housing, a swing rod assembly, a driving assembly, a detection switch, and a controller. The swing rod assembly includes a swing rod, a vertical shaft, a bushing, and a torsion spring. The vertical shaft is fixed inside the housing. The bushing is sleeved on the vertical shaft, and a torsion spring is arranged between the bushing and the vertical shaft. The swing rod is installed on the bushing. One end of the swing rod is located inside the housing, and the other end extends outside the housing. When the swing rod swings, the swing rod diverts the plants discharged from the end of the horizontal conveying assembly.

[0007] The driving assembly includes a driving disk, a connecting rod, a first-level slide rail, a first-level slider, and a limiter. The first-level slider is installed on the first-level slide rail. A second-level slide rail parallel to the first-level slide rail is arranged on the first-level slider. A second-level slider is arranged on the second-level slide rail. A push rod and a functional block are respectively arranged at both ends of the second-level slide rail. A first electromagnet capable of adsorbing the second-level slider is arranged inside the functional block. Both ends of the connecting rod are respectively hinged to the driving disk and the second-level slider. The driving disk drives the second-level slider to reciprocate along the second-level slide rail through the connecting rod and drives the first-level slider to reciprocate along the first-level slide rail. In the present invention, the driving disk, the connecting rod, and the second-level slider form a crank and connecting rod mechanism. Therefore, the hinge point between the connecting rod and the driving disk cannot be located at the center point of the driving disk.

[0008] The basic operating principle of the first-level slider and the second-level slider is as follows: The connecting rod is hinged to the second-level slider. When the connecting rod moves, the connecting rod directly drives the second-level slider to move. The specific movements of the second-level slider and the first-level slider are divided into two cases. Case 1: The functional block adsorbs the second-level slider. At this time, the second-level slider cannot slide on the second-level slide rail, and the second-level slider will translate along the first-level slide rail synchronously with the first-level slider. The push rod installed on the first-level slider translates synchronously. At this time, the push rod can reach a relatively far limit position in the reciprocating movement, which is called the first limit position. Case 2: The functional block does not adsorb the second-level slider. At this time, the second-level slider affected by the connecting rod first translates along the second-level slide rail (the first-level slider remains stationary). When the second-level slider touches the push rod, the second-level slider will push the first-level slider to translate along the first-level slide rail. The push rod installed on the first-level slider translates synchronously. At this time, the push rod can reach a relatively close limit position in the reciprocating movement, which is called the second limit position.

[0009] The swing rod is located on the reciprocating movement path of the push rod. The limiter is installed inside the housing and located on the swinging path of the swing rod. The limiter is used to adsorb and release the swing rod. When the push rod translates, it pushes the swing rod to swing and deforms the torsion spring to store energy. When the push rod translates to the first limit position, the swing rod reaches the position of the limiter and is restricted by the limiter. The function of the limiter is to control the swinging timing of the swing rod. Generally, a second electromagnet can be used as the limiter, or a controllable movable hook can also be used as the limiter.

[0010] The detection switch is installed on the frame and located in the movement path of the plant. After the detection switch detects the passing of the plant, the detection switch sends a signal to the controller, and the controller controls the function block and the stopper; the detection switch can be an optoelectronic switch;

[0011] In the initial state, the swing rod is adsorbed by the stopper, the torsion spring is in a deformed energy storage state, the function block does not adsorb the secondary slider. At this time, the push rod reciprocates between the starting position and the second limit position, and the push rod will not touch the swing rod. And the second limit position should ensure that even if the swing rod swings, the push rod will not touch the swing rod. After the swather starts working, the horizontal conveying component starts to convey the cut plants. After the detection switch detects the passing of the plants, it sends a signal to the controller. After receiving the signal from the detection switch, the controller performs operations according to the sequence number of the received signal. If this is the Nth signal received by the controller and N is an even number, the controller first controls the stopper to release the swing rod. The swing rod swings under the action of the torsion spring, and the swing rod generates a horizontal force on the plants leaving the horizontal conveying component, so that the plants tilt towards the left front or the right front of the swather at a certain angle. After a first set time (the first set time is a parameter set manually, and the first set time should ensure that the swing rod has swung in place), the controller controls the function block to adsorb the secondary slider and the second electromagnet is energized. At this time, the secondary slider will drive the push rod to reach the first limit position during reciprocating motion. The push rod pushes the swing rod to swing back again and is adsorbed by the stopper during this process; after a second set time (the second set time is a parameter set manually, and the second set time should ensure that the push rod can perform at least one reciprocating action), the controller controls the function block to release the secondary slider; if this is the Nth signal received by the controller and N is an odd number, the controller does not perform an operation, and the plants will freely leave from the end of the horizontal conveying component; in the present invention, the controller can also swap the operations in the cases where N is an even number and N is an odd number; the functions of the detection switch and the controller are to precisely control the swing rod to ensure that the plants can be acted on by the swing rod at intervals, and finally form a stacked state where the lower-layer plants and the upper-layer plants cross each other.

[0012] Further, the swing rod includes a square rod section and a round rod section, and the stopper is located on the swing path of the square rod section of the swing rod. The square rod section makes the contact area between the swing rod and the stopper larger, which is beneficial for the stopper to adsorb the swing rod.

[0013] Further, the swing rod assembly further includes a first substrate, a second substrate, and a spring. The first substrate is fixed on the bushing. Two ends of the spring are respectively connected to the first substrate and the second substrate. A guide groove parallel to the swing rod is provided on the bushing. A guide plate inserted into the guide groove is provided on the second substrate, and the guide plate is inserted into the guide groove. A square hole matching the square rod section is provided on the first substrate. An external thread section is provided on the round rod section. A threaded hole matching the external thread of the round rod section is provided on the second substrate. The round rod section is threadedly connected to the second substrate and the square rod section is inserted into the square hole. After the swing rod is installed, since the square rod section of the swing rod is located in the square hole of the first substrate, the swing rod will not rotate even when working in a long-term vibration environment, avoiding the swing rod from disengaging from the threaded hole.

[0014] The installation method of the swing rod is as follows: Push the second substrate to compress the spring and approach the first substrate, then insert the round rod section of the swing rod into the threaded hole of the second substrate for installation. At this time, the square rod section of the swing rod does not enter the square hole of the first substrate, and the swing rod can still be rotated. After the round rod section of the swing rod is screwed into the threaded hole of the second substrate, appropriately rotate the swing rod so that the square rod section of the swing rod is aligned with the square hole of the first substrate, and then release the second substrate. The second substrate translates under the action of the spring, and the swing rod translates with the second substrate and the square rod section of the swing rod is inserted into the square hole of the first substrate.

[0015] Further, a storage sleeve is provided on the housing. The storage sleeve is aligned with the swing rod. One end of the storage sleeve connected to the housing is in a flared shape. A locking screw is provided on the surface of the storage sleeve. When the swather is not working, the square rod section of the swing rod can be inserted into the storage sleeve and locked with the locking screw to avoid safety problems caused by the exposed swing rod.

[0016] Specifically, the horizontal conveying assembly includes a sprocket and a conveyor belt wound around the sprocket. External teeth are provided on the surface of the conveyor belt.

[0017] Further, the driving assembly further includes a connecting shaft. The connecting shaft is installed in the housing. One end of the connecting shaft is connected to the driving disk, and the other end is provided with a connecting disk. The connecting disk is located outside the housing and is connected to the sprocket. The driving disk is driven by the sprocket of the swather.

[0018] Beneficial effects: (1) The self-regulating legume windrower of the present invention uses a detection switch to detect the plants in the horizontal conveying assembly. The swing rod can swing specifically according to the arrival of the plants, making the lodging posture of the plants more regular and controllable, which is beneficial to forming a stable cross-stacked state of the upper and lower layer plants and promoting the drying of the fruits on the plants. (2) The self-regulating legume windrower of the present invention uses two-stage slide rails and two-stage sliders to realize the movement of the push rod, ensuring that the push rod can controlledly change the limit position during the continuous reciprocating movement, which can not only push the swing rod to a suitable standby position but also ensure that the push rod does not occupy the position where the swing rod swings back. (3) The self-regulating legume windrower of the present invention designs the swing rod in a combined form of a square rod section and a round rod section. Cooperating with the first substrate and the second substrate, the swing rod can be installed by threads and limited by a square hole, so that the swing rod will not rotate automatically in the long-term vibration environment, effectively overcoming the defect of the swing rod loosening and falling off.

Specific embodiments

[0033] The present invention will be further described in detail below in conjunction with specific embodiments.

[0034] Embodiment 1

[0035] As Figure 2 and Figure 3 shown, the self-adjusting legume swather of this embodiment includes a frame 100, a dividing board 200, a cutter 300, a horizontal conveying component 400, a diverter 500 and a walking tractor 600;

[0036] The frame 100 is mounted on the walking tractor 600, the dividing board 200 is arranged in front of the frame 100, a star wheel 210 is arranged on the dividing board 200, both the cutter 300 and the horizontal conveying component 400 are mounted on the frame 100, and the cutter 300 is located at the bottom of the frame 100; the horizontal conveying component 400 includes a sprocket 410 and a conveyor belt 420 wound around the sprocket 410, and the surface of the conveyor belt 420 is provided with external teeth; the frame 100, the dividing board 200, the star wheel 210, the cutter 300 and the horizontal conveying component 400 are the same as those in the prior art; in this embodiment, two horizontal conveying components 400 are arranged on the frame 100, which are respectively used for conveying the upper half and the lower half of the plant, and the upper horizontal conveying component 400 is slightly longer in size than the lower horizontal conveying component 400 to ensure that the plant can fall in a manner with the top facing forward.

[0037] As Figures 2 to 5As shown in the figure, the diverter 500 is installed on the rack 100 and is located at the end of the upper horizontal conveying assembly 400. The diverter 500 includes a housing 510, a swing rod assembly 520, a drive assembly 530, a detection switch 540 and a controller. The swing rod assembly 520 includes a swing rod 521, a vertical shaft 522, a bushing 523, a torsion spring 524, a first substrate 525, a second substrate 526 and a spring 527. The vertical shaft 522 is fixed inside the housing 510. The bushing 523 is sleeved on the vertical shaft 522, and a torsion spring 524 is arranged between the bushing 523 and the vertical shaft 522. As Figure 7 shown, the swing rod 521 includes a square rod section 521-1 and a round rod section 521-2, and an external thread is provided on the round rod section 521-2.

[0038] As Figures 8 to 10 shown, the first substrate 525 is fixed on the bushing 523. The two ends of the spring 527 are respectively connected to the first substrate 525 and the second substrate 526. A guide groove 523-1 parallel to the swing rod 521 is arranged on the bushing 523, and a guide plate 526-1 inserted into the guide groove 523-1 is arranged on the second substrate 526. The guide plate 526-1 is inserted into the guide groove 523-1; a square hole matching the square rod section 521-1 is arranged on the first substrate 525, and a threaded hole matching the external thread of the round rod section 521-2 is arranged on the second substrate 526; the round rod section 521-2 is threadedly connected to the second substrate 526 and the square rod section 521-1 is inserted into the square hole. As Figure 5 shown, in this embodiment, one end of the swing rod 521 is located inside the housing 510 and the other end extends outside the housing 510; after the swing rod 521 is installed, since the square rod section 521-1 of the swing rod 521 is located in the square hole of the first substrate 525, the swing rod 521 will not rotate even when working in a long-term vibration environment, avoiding the swing rod 521 from disengaging from the threaded hole.

[0039] In this embodiment, the installation method of the swing rod 521 is as follows: As Figure 11 shown, push the second substrate 526 to translate along the guide groove 523-1. The second substrate 526 compresses the spring 527 and approaches the first substrate 525. Then insert the round rod section 521-2 of the swing rod 521 into the threaded hole of the second substrate 526 for installation. At this time, the square rod section 521-1 of the swing rod 521 does not enter the square hole of the first substrate 525, and the swing rod 521 can still be rotated; after the round rod section 521-2 of the swing rod 521 is screwed into the threaded hole of the second substrate 526, appropriately rotate the swing rod 521 so that the square rod section 521-1 of the swing rod 521 is aligned with the square hole of the first substrate 525, and then release the second substrate 526. The second substrate 526 translates under the action of the spring 527, and the swing rod 521 translates along with the second substrate 526 and the square rod section 521-1 of the swing rod 521 is inserted into the square hole of the first substrate 525.

[0040] AsFigures 4 to 6 As shown, the driving assembly 530 includes a driving disk 531, a connecting rod 532, a first-stage slide rail 533, a first-stage slider 534, a limiter 535, and a connecting shaft 536. The first-stage slider 534 is installed on the first-stage slide rail 533. A second-stage slide rail 534-1 parallel to the first-stage slide rail 533 is provided on the first-stage slider 534. A second-stage slider 534-2 is provided on the second-stage slide rail 534-1. Push rods 534-3 and functional blocks 534-4 are respectively provided at both ends of the second-stage slide rail 534-1. A first electromagnet capable of adsorbing the second-stage slider 534-2 is provided in the functional block 534-4. Both ends of the connecting rod 532 are respectively hinged to the driving disk 531 and the second-stage slider 534-2. The driving disk 531 drives the second-stage slider 534-2 to reciprocate along the second-stage slide rail 534-1 through the connecting rod 532 and drives the first-stage slider 534 to reciprocate along the first-stage slide rail 533. In this embodiment, a second electromagnet is used as the limiter 535. The limiter 535 is located on the swinging path of the square rod section 521-1 of the swing rod 521, and the limiter 535 can adsorb and release the square rod section 521-1 of the swing rod 521. The connecting shaft 536 is installed in the housing 510. One end of the connecting shaft 536 is connected to the driving disk 531, and a connecting disk is provided at the other end. The connecting disk is located outside the housing 510 and is connected to the sprocket 410. The driving disk 531 is driven by the sprocket 410 of the swather.

[0041] In this embodiment, the basic operating principle of the first-stage slider 534 and the second-stage slider 534-2 is as follows: The connecting rod 532 is hinged to the second-stage slider 534-2. When the connecting rod 532 moves, the connecting rod 532 directly drives the second-stage slider 534-2 to move. The specific movements of the second-stage slider 534-2 and the first-stage slider 534 are divided into two cases; Case 1: The functional block 534-4 adsorbs the second-stage slider 534-2. At this time, the second-stage slider 534-2 cannot slide on the second-stage slide rail 534-1. The second-stage slider 534-2 will translate along the first-stage slide rail 533 synchronously with the first-stage slider 534. The push rod 534-3 installed on the first-stage slider 534 translates synchronously. At this time, the push rod 534-3 can reach a relatively far extreme position as shown in Figure 12 during the reciprocating motion, which is called the first extreme position; Case 2: The functional block 534-4 does not adsorb the second-stage slider 534-2. At this time, the second-stage slider 534-2 under the action of the connecting rod 532 first translates along the second-stage slide rail 534-1 (the first-stage slider 534 remains stationary). When the second-stage slider 534-2 touches the push rod 534-3, the second-stage slider 534-2 will push the first-stage slider 534 to translate along the first-stage slide rail 533. The push rod 534-3 installed on the first-stage slider 534 translates synchronously. At this time, the push rod 534-3 can reach a relatively near extreme position as shown in Figure 13 during the reciprocating motion, which is called the second extreme position.

[0042] ​The detection switch 540 is installed on the frame 100 and is located in the movement path of the plant. After the detection switch 540 detects that the plant has passed by, the detection switch 540 sends a signal to the controller, and the controller controls the function block 534-4 and the stopper 535.

[0043] As Figure 5 shown, a storage sleeve 511 is provided on the outer shell 510. The storage sleeve 511 is aligned with the swing rod 521. One end of the storage sleeve 511 connected to the outer shell 510 is in a flared shape, and a locking screw 512 is provided on the surface of the storage sleeve 511; when the swather is not working, the square rod section 521-1 of the swing rod 521 can be inserted into the storage sleeve 511 and locked by the locking screw 512 to avoid safety problems caused by the exposure of the swing rod 521.

[0044] The basic working principle of the self-adjusting legume swather in this embodiment is:

[0045] (1) As Figure 5 shown, in the initial state, the swing rod 521 is adsorbed by the stopper 535, the torsion spring 524 is in a deformed energy storage state, and the function block 534-4 does not adsorb the secondary slider 534-2. At this time, the drive disk 531 is continuously rotated by the sprocket 410 of the swather. Correspondingly, the push rod 534-3 reciprocates between the starting position and the second limit position as shown in Figure 13 shown, and the push rod 534-3 does not touch the swing rod 521; Figure 13 The dotted line in the figure shows the position that the swing rod 521 can reach after the stopper 535 releases the swing rod 521. It can be seen that even if the swing rod 521 swings, the push rod 534-3 will not touch the swing rod 521.

[0046] (2) After the swather starts to work, the cutter 300 cuts off the roots of the legume plants, and the horizontal conveying assembly 400 starts to convey the cut plants. After the detection switch 540 detects that the plants have passed by, it sends a signal to the controller. After receiving the signal from the detection switch 540, the controller performs operations according to the sequence number of the received signal. If this is the Nth signal received by the controller and N is an even number, the controller first controls the stopper 535 to release the swing rod 521. The swing rod 521 swings under the action of the torsion spring 524. As Figure 13 shown, the swing rod 521 will swing to the dotted line position; the swing rod 521 generates a horizontal force on the plants leaving the horizontal conveying assembly 400, so that the plants tilt towards the left front or right front of the swather at a certain inclination angle. After a first set time (the first set time is a parameter set manually, and the first set time should ensure that the swing rod 521 has swung in place), the controller controls the function block 534-4 to adsorb the secondary slider 534-2 and controls the second electromagnet serving as the stopper 535 to be energized. At this time, the secondary slider 534-2 will drive the push rod 534-3 to reach as shown in the reciprocating movementFigure 12 The first limit position shown, in this process, the push rod 534-3 pushes the swing rod 521 to swing back again and is adsorbed by the stopper 535; after the second set time (the second set time is a parameter set manually, and the second set time should ensure that the push rod 534-3 can perform at least one reciprocating motion), the controller controls the function block 534-4 to release the secondary slider 534-2, and at this time, the push rod 534-3 will continue to move reciprocally between the starting position shown in Figure 5 and the second limit position shown in Figure 13 ; if this is the Nth signal received by the controller and N is odd, the controller does not perform an operation, and the plant will freely leave from the end of the horizontal conveying assembly 400;

[0047] Through the detection switch 540 and the intelligent control of the controller, the swing rod 521 in this embodiment can accurately push the plant, and the swing rod 521 will act on the plant at intervals, so that the finally lodged plants form a stacked state where the lower-layer plants and the upper-layer plants cross each other as shown in Figure 1 .

[0048] In this embodiment, the controller is mainly used to control the swing rod 521 to act on the plant at intervals. Therefore, in the above working principle, the controller can also swap the operations in the cases where N is even and N is odd, that is, when N is odd, control the swing rod 521 to act, and when N is even, the swing rod 521 does not act.

[0049] Although the embodiments of the present invention are described in the specification, these embodiments are only for reference and should not limit the protection scope of the present invention. All omissions, substitutions, and changes made without departing from the spirit of the present invention should be included in the protection scope of the present invention.
