[0001] The invention relates to the technical field of agricultural machinery, and in particular to a fully automatic compression, packaging and stacking device for square straw bales. Background Art

[0002] Straw usually refers to the remaining part of coarse grains after the seeds are harvested. Straw is a renewable biological resource with multiple uses. In the process of straw recycling, it needs to be baled, compressed and stacked before transportation. Among them, square straw bales are the most commonly used bale type.

[0003] The existing straw square bale device has the following problems in actual use: Since crops are affected by many external factors during their growth process, the size of the crops after they grow is different.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The implementation method of the present invention is a reference Figure 1 as well as Figure 4 As shown, the present embodiment provides a fully automatic compression, packaging and stacking device for square bales of straw, the device comprising a mounting frame 1, a baling mechanism 2, a first conveyor belt 3, a stacking support frame 4, a baling compression chamber 6, a frame 12, a first push rod 401, a push plate 402, an L-shaped flip plate 7, a closed door 8 and a driver 9, and the components are arranged as follows: The mounting frame 1, the baling mechanism 2, the first conveyor belt 3, the stacking support frame 4 and the baling compression chamber 6 are all fixedly arranged on the vehicle frame 12. The baling mechanism 2 realizes the shape preservation of the straw after compression by rotating winding. The input end of the first conveyor belt 3 is arranged corresponding to the output end of the baling mechanism 2. The output end of the first conveyor belt 3 is connected to the input end of the stacking support frame 4. At least one baling compression chamber 6 is arranged.

[0023] The setting direction of the first conveyor belt 3 is perpendicular to the setting direction of the stacking support frame 4. The stacking support frame 4 is provided with a first push rod 401 whose output end extends to its working area. The output end of the first push rod 401 is fixedly connected with a push plate 402. The stacking direction of the straw balls is changed by the first push rod 401 and the push plate 402, thereby ensuring the stacking effect of the stacking support frame 4.

[0024] The baling compression chamber 6 is provided with a compression mechanism 10 for compressing the straw. The compression mechanism 10 includes a longitudinal cylinder 1001, a first pressing plate 1002, a transverse cylinder 1011 and a second pressing plate 1012.

A movable groove for accommodating the second pressing plate 1012 is opened on the inner wall of the baling compression chamber 6. In the initial state, one side of the inner end of the second pressing plate 1012 is horizontally aligned with the inner wall of the baling compression chamber 6. The longitudinal cylinder 1001 and the first pressing plate 1002 are used to compress the straw in the vertical direction, and then the transverse cylinder 1011 and the second pressing plate 1012 are used to compress the straw in the horizontal direction.

[0025] The L-shaped flip plate 7 is pin-mounted on the baling compression chamber 6. In its initial state, the L-shaped flip plate 7 is movably opposed to the upper surface of the mounting frame 1. The closing door 8 is pin-mounted on one side of the baling compression chamber 6. The closing door 8 is arranged corresponding to the input end of the baling mechanism 2, so that the baling compression chamber 6 is in a closed state when the straw is compressed. When the straw compression operation is completed, the closing door 8 is opened, and the compressed straw is pushed to the baling mechanism 2 for baling through the transverse cylinder 1011 and the second pressing plate 1012.

[0026] The two drivers 9 are respectively arranged on two adjacent side walls of the baling and compression chamber 6. The two drivers 9 are respectively used to drive the L-shaped flip plate 7 and the closed door 8 to flip. The two drivers 9 include a fifth push rod 901 and a cam 902. The components are arranged as follows: Two fifth push rods 901 are installed on both sides of the baling and compression chamber 6, and two cams 902 are fixedly sleeved on the shaft body for installing the closed door 8 and the shaft body for installing the L-shaped flip plate 7, respectively. The cam 902 is movably connected with the output end of the fifth push rod 901. The cam 902 is pushed by the fifth push rod 901 to rotate, so that the L-shaped flip plate 7 can continue to rotate 90°, so as to facilitate the transfer of straw to the baling and compression chamber 6. The movable connection is one of a sliding connection, a movable offset or a pin connection, which is as follows: When a sliding connection is adopted, a sliding groove needs to be provided on the cam 902. The sliding groove needs to be provided correspondingly according to the shape of the outer edge of the cam 902, and a sliding block that is slidingly connected to the sliding groove needs to be fixedly connected to the output end of the fifth push rod 901; When the movable offset is adopted, a torsion spring fixedly connected to the cam 902 needs to be movably mounted on the shaft for installing the closed door 8 and the shaft for installing the L-shaped flip plate 7, and the torsion spring is fixedly connected to the outer wall of the baling compression chamber 6, and the smaller arc end of the cam 902 is movably offset against the output end of the fifth push rod 901, and the cam 902 is in a vertical state when the torsion spring is not subjected to external force, and the elastic force of the torsion spring is used to make the cam 902 move toward the initial state when it is not affected by external force, so as to ensure that the output end of the fifth push rod 901 and the cam 902 always keep the movable offset; When a pin connection is adopted, a connecting rod needs to be connected by a pin between the output end of the fifth push rod 901 and the cam 902, so as to compensate for the position difference generated when the cam 902 rotates through the connecting rod.

[0027] When using the straw square bale device, follow the steps below: The fifth push rod 901 near the L-shaped flip plate 7 is started, and the fifth push rod 901 drives the cam 902 to rotate, and the cam 902 drives the L-shaped flip plate 7 to rotate 90 degrees, so that the straw on the L-shaped flip plate 7 slides into the baling compression chamber 6 under the action of gravity; The longitudinal cylinder 1001 is started, and the longitudinal cylinder 1001 drives the first pressing plate 1002 to squeeze the straw. After the longitudinal compression of the straw is completed, the longitudinal cylinder 1001 drives the first pressing plate 1002 away from the straw. At this time, the transverse cylinder 1011 is started, and the transverse cylinder 1011 drives the second pressing plate 1012 to squeeze the straw, thereby completing the straw compression operation; The fifth push rod 901 near the closed door 8 is started, and the fifth push rod 901 drives the cam 902 to rotate, and the cam 902 drives the closed door 8 to rotate 90 degrees upward, and the transverse cylinder 1011 is started to drive the second pressing plate 1012 to squeeze the straw square ball, so that the straw square ball moves to the baling mechanism 2 for baling. After the straw square ball is baled, the transverse cylinder 1011 is continued to be started, and the transverse cylinder 1011 drives the second pressing plate 1012 to push the straw square ball to move to the first conveyor belt 3; The first conveyor belt 3 is started, the straw balls are moved to the push plate 402, the first push rod 401 is started, and the first push rod 401 drives the straw balls to move to the stacking support frame 4 through the push plate 402, so as to realize the stacking operation of the straw balls.

[0028] Implementation Method 2 refer to Figure 1 and Figures 2 to 3As shown, on the basis of implementation method 1, in order to ensure that the weight of the straw is always within the preset weight range when it is grabbed, the second conveyor belt 13 and the transfer robot 5 are introduced in this implementation method. The specific implementation method is as follows: The second conveyor belt 13 is fixedly arranged on the mounting frame 1. The second conveyor belt 13 is used to transport the straw to the L-shaped flip plate 7. The second conveyor belt 13 is used as a connecting component between the L-shaped flip plate 7 and the transfer robot 5 to provide sufficient working time for the transfer robot 5. The transfer robot 5 includes a support frame 501, a drive motor 502, a connecting frame 503, a drive frame 504, a second push rod 505, a weighing device 506, a third push rod 507, a clamp 508, a mounting cavity 509, a bidirectional electric slide 510, a clamping plate 511 and an image recognition component 512. The components are arranged as follows: The support frame 501 is mounted on the vehicle frame 12, the driving motor 502 is fixed on the support frame 501, and the connecting frame 503 is rotatably mounted on the bottom end of the driving motor 502. The connecting frame 503 is driven to rotate by the driving motor 502, so that the connecting frame 503 can rotate according to actual needs, which helps to improve the operating range of the transfer robot 5; The pin shaft of the driving frame 504 is installed at the upper end of the connecting frame 503, and the pin shaft of the second push rod 505 is installed between the middle end of the driving frame 504 and the lower end of the connecting frame 503, so that the driving frame 504 can be deflected downward according to actual needs. During the deflection process, the horizontal position of the driving frame 504 away from the end point of the connecting frame 503 is offset, further improving the operating range of the transfer robot 5; The pin shaft of the weighing device 506 is installed on the driving frame 504, so that the weighing device 506 always maintains a vertical downward state under the action of gravity, the third push rod 507 is installed at the lower end of the weighing device 506, and the clamp 508 is installed at the lower end of the third push rod 507. The weighing device 506 senses the weight of the straw clamped by the clamp 508, and then determines whether the weight of the clamped straw meets the preset range, and uses the third push rod 507 to adjust the height position of the clamp 508; The installation cavity 509 is opened on the clamp 508, and the bidirectional electric slide 510 is installed in the installation cavity 509. The bidirectional electric slide 510 is electrically connected to the weighing device 506. The two clamping plates 511 are respectively slidably installed on the two sides of the installation cavity 509. The two clamping plates 511 are horizontally driven by the bidirectional electric slide 510. It should be noted that the bidirectional electric slide 510 is composed of a motor, a bidirectional lead screw, and two nuts. An L-shaped driving rod is connected between the nuts and the clamping plates 511. The image recognition component 512 is installed on the clamp 508. The image recognition component 512 is electrically connected to the driving motor 502, the second push rod 505, the third push rod 507 and the weighing device 506. The image recognition component 512 is used to perform image analysis and recognition on the area where the straw is stacked, so as to avoid the transfer robot 5 from grabbing empty straw, and control the transfer robot 5 to grab the straw again or put down some straw when grabbing less straw or grabbing more straw.

[0029] When using the straw square bale device, follow the steps below: The driving motor 502 is started to drive the connecting frame 503 to rotate, and the driving motor 502 is stopped when the image recognition component 512 recognizes the straw. At this time, the connecting frame 503 drives the clamp 508 to move to the area where the straw is stacked through the driving frame 504; The third push rod 507 is started to drive the clamp 508 to move vertically downward. When the clamping plate 511 contacts the straw, the bidirectional electric slide 510 is started so that the two clamping plates 511 can fix and clamp the straw. The third push rod 507 is started to drive the clamp 508 to move vertically upward. At this time, the weighing device 506 senses the weight of the straw clamped by the clamping plate 511. When the weight of the clamped straw exceeds a preset range, the bidirectional electric slide 510 is started, so that the two clamping plates 511 move in opposite directions, and the straw moves downward under the action of gravity. When the weighing device 506 detects that the weight of the clamped straw meets the preset range, the bidirectional electric slide 510 drives the two clamping plates 511 to move in opposite directions, and clamps the straw to a limited position; When the weight of the clamped straw is lower than the preset range, the image recognition component 512 identifies the direction of the straw below, and starts the second push rod 505, which drives the driving frame 504 to deflect downward, so as to adjust the horizontal position of the clamp 508 and the weighing device 506, and starts the two-way electric slide 510, so that the two clamping plates 511 move in opposite directions, and the straw falls to the bottom under the action of gravity, and starts the third push rod 507 to drive the clamp 508 to move vertically downward. When the clamping plate 511 contacts the straw, the two-way electric slide 510 is started to drive the two clamping plates 511 to fix and clamp the straw, and the third push rod 507 is started to drive the clamp 508 to move vertically upward. If the weight of the clamped straw exceeds the preset range at this time, the above operation is repeated; When the weight of the clamped straw is within a preset range, the drive motor 502 is started to drive the connecting frame 503 to rotate. When the image recognition component 512 recognizes the second conveyor belt 13, the drive motor 502 is stopped, and the bidirectional electric slide 510 is started to drive the two clamping plates 511 to move in opposite directions, so that the straw falls onto the second conveyor belt 13 due to gravity, and is transferred to the L-shaped flip plate 7 through the second conveyor belt 13.

[0030] Implementation method three refer to Figures 6 to 9 As shown, on the basis of the second implementation method, in order to reduce the gap between the straws, the present implementation method introduces a storage groove 1003, a force plate 1004, a connecting rod 1005, a cutting blade 1006, a return spring 1007, a mounting plate 1008, a fourth push rod 1009 and a wedge block 1010. The specific implementation method is as follows: The storage groove 1003 is opened on the first pressure plate 1002, the force plate 1004 is movably mounted on the output end of the longitudinal cylinder 1001, the connecting rod 1005 is arranged on the bottom end of the force plate 1004, and the lower end of the connecting rod 1005 extends into the storage groove 1003. At least one connecting rod 1005 is arranged, and a cutting blade 1006 is fixed at the lower end of the connecting rod 1005. The cutting blade 1006 is used to squeeze and cut the straw, so that a single straw is cut into multiple sections of straw. By reducing the volume of the straw itself, the gap between the straws is reduced, which helps to ensure the compaction of the straw ball after compression.

[0031] The return spring 1007 is connected between the force plate 1004 and the first pressure plate 1002 and is equal to the number of the connecting rod 1005. The return spring 1007 is movably mounted on the connecting rod 1005. The elastic force of the return spring 1007 is used to make the connecting rod 1005 move toward the initial state until it is reset when it is not affected by external force. The first pressure plate 1002 is provided with an active through hole connected to the storage groove 1003, and the active through hole is used to movably mount the connecting rod 1005, thereby providing a movable space for the connecting rod 1005 and guiding and limiting the connecting rod 1005, so that the movement trajectory of the connecting rod 1005 is single. The mounting plate 1008 is mounted on the first pressure plate 1002, the fourth push rod 1009 is mounted on the mounting plate 1008, the wedge block 1010 is arranged on the output end of the fourth push rod 1009, the thinner end of the wedge block 1010 is movably offset against the force plate 1004, at least two wedge blocks 1010 are arranged, and the wedge blocks 1010 are arranged in even numbers. The two wedge blocks 1010 are symmetrically arranged on both sides of the output end of the longitudinal cylinder 1001, and are driven by two points, which helps to ensure the smoothness of the force plate 1004 when it is subjected to force. Through the movably offsetting action of the wedge block 1010 and the force plate 1004 and the driving action of the fourth push rod 1009, the cutting blade 1006 connected to the force plate 1004 through the connecting rod 1005 has vertical telescopic performance.

[0032] When using the straw square bale device, follow the steps below: The fourth push rod 1009 is started, and the fourth push rod 1009 drives the wedge block 1010 to squeeze the force plate 1004. The force plate 1004 is forced to move downward, and drives the connecting rod 1005 to move downward, so that the return spring 1007 structure contracts, and the connecting rod 1005 drives the cutting blade 1006 away from the storage groove 1003, and the longitudinal cylinder 1001 is started. The longitudinal cylinder 1001 drives the first pressing plate 1002 to move downward. At this time, the cutting blade 1006 contacts the straw before the first pressing plate 1002, so that the straw The straw is cut into multiple sections. When the cutting blade 1006 contacts the bottom of the baling compression chamber 6, the fourth push rod 1009 is started. The fourth push rod 1009 drives the wedge block 1010 away from the force plate 1004. Under the elastic force of the reset spring 1007, the force plate 1004 moves toward the initial state until it is reset. The connecting rod 1005 drives the cutting blade 1006 to enter the storage groove 1003. At this time, the longitudinal cylinder 1001 continues to work, and the longitudinal cylinder 1001 drives the first pressing plate 1002 to compress the straw longitudinally.

[0033] Implementation Method 4 refer to Figures 5 and 6 As shown, on the basis of implementation method 3, in order to ensure the regularity of the straw, a control component 11 is introduced in this implementation method, and the specific implementation method is as follows: The baling and compression chamber 6 is provided with a control assembly 11 for controlling the opening and closing of the longitudinal cylinder 1001. The control assembly 11 includes a light transmitter 1101, a light receiver 1102 and a controller 1103. The components are arranged as follows: The light transmitter 1101 is arranged on the inner wall of the baling compression chamber 6, the light receiver 1102 is arranged at one end of the first pressing plate 1002 close to the light transmitter 1101, the light receiver 1102 is electrically connected to the longitudinal cylinder 1001, and the controller 1103 is installed on the first pressing plate 1002. The controller 1103 is the core of the control component 11. The controller 1103 is an electronic control unit. The controller 1103 is used to detect and control the longitudinal cylinder 1001 and obtain and process the detection signal.

[0034] When using the straw square bale device, follow the steps below: Start the light emitter 1101. During the downward squeezing of the first pressing plate 1002, the light emitted by the light emitter 1101 is received by the light receiver 1102 twice. The first time is when the light emitted by the light emitter 1101 is received by the light receiver 1102 during the downward squeezing of the first pressing plate 1002. The second time is when the first pressing plate 1002 stops squeezing down and rises up, and the light emitted by the light emitter 1101 is received by the light receiver 1102.
