Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of straw baling, and particularly relates to an intelligent and efficient continuous straw baling device. BACKGROUND

[0002] The straw baling machine is used for baling and forming the straw and grass, such as corn straw, rice straw, grain straw, peanut straw and sheep grass, which are left in rural areas. According to the search, the patent CN220157092U proposes a straw baling machine. The first motor drives the rotating roller to rotate, the rotating roller drives the straw fork to rotate, the straw fork rolls up the straw in the field, the straw falls onto the conveying belt when reaching the top of the conveying mechanism by relying on its own gravity, the second motor drives the driving shaft to rotate, the driving shaft drives the conveying belt to rotate, the conveying belt conveys the straw into the baling machine body, the baling machine body bales the straw, and the baled straw gradually moves to the discharge port under the extrusion of the continuously conveyed straw on the conveying mechanism, and finally falls from the discharge port.

[0003] The baling machine has the following disadvantages: 1. In the process of rolling up the straw by the straw fork, the front end of the straw fork is mainly in contact with the straw, and the fibers are easily hooked on the front end of the straw fork, especially in the case of high humidity of the straw, the winding phenomenon is more likely to occur, and there is no automatic cleaning structure for the wound straw. When the winding occurs, it can only be cleaned by manual operation, which reduces the work efficiency, increases the labor intensity of the operator, and affects the overall operation progress.

[0004] 2. When the straw fork moves to the stone or pit (such as the pit on the cement ground for drying the straw), it cannot rotate. If the straw fork is forced to rotate at this time, it will cause harm to the motor and the straw fork. For the motor, the straw fork cannot rotate, which will cause the load of the motor to increase sharply, and long-time forced operation will cause the winding of the motor to overheat and burn out. For the straw fork, the huge force generated by forced rotation will cause the straw fork to bear excessive stress, resulting in bending, deformation or even breakage of the straw fork. SUMMARY

[0015] The intelligent and efficient continuous rice straw packaging device has the following beneficial effects. 1. The cleaning structure is provided, and in the initial state, that is, during normal operation, the centrifugal force generated by the motor on the rotating roller cannot overcome the resistance of the tension spring on the movable block due to the low rotating speed of the motor, so that the movable block is in a static state during normal feeding. When the rice straw is removed, the rotating speed is increased, and the centrifugal force on the fork grass rod is significantly increased. At this time, the centrifugal force generated can overcome the resistance of the tension spring on the movable block, and then the movable block moves along the sliding groove and lengthens the tension spring. When the movable block moves, the protection plate is opened by the top rod, and then the movable block and the blade are separated from the inside of the second protective shell. At this time, the purpose of the second protective shell is to block the blade, so as to prevent the blade from being exposed and cutting the rice straw during normal operation. The position where the protection plate contacts the second protective shell is provided with a sealing ring, which can prevent rainwater from entering the blade and rusting the blade in rainy days. When it is necessary to further cut the wrapped rice straw, the rotating speed of the motor needs to be reduced, and then the centrifugal force is reduced. The tension spring is reset with the movable block, and then acts on the protection plate to make it rotate. Then the movable block returns to the inside of the second protective shell. The torsional spring hinge facilitates the rotation of the protection plate. After the reset, the rotating speed of the motor is increased again, and then the centrifugal force is increased. The movable block repeats the above operation to further cut the rice straw. The automatic removal of the rice straw is realized, and manual operation is not required, which improves the work efficiency, reduces the labor intensity of the operator, and improves the overall operation progress.

[0016] 2、By setting the separation structure, when the fork grass pole moves to the stone or the pit, it cannot rotate, at this time the torque of the motor increases with the rotation of the round shaft, the fork grass pole on the rotating roller cannot rotate, so that the rotating roller and the iron block are in a static state, the baffle is stopped by the static iron block, with the continuous rotation of the round shaft, the high stiffness spring is compressed under the action of large torque, then the iron block comes to the position away from the electromagnet, at this time the iron block is separated from the electromagnet, so the reset spring resets the iron block from the groove and retracts into the hollow block, at this time the shell and the round shaft are connected due to the lack of connecting parts, so the motor rotates with the round shaft, at this time the current of the electromagnet is not strong, so the magnetic attraction to the iron block is general, so the electromagnet will not magnetically attract the iron block when the round shaft rotates, the purpose is to prevent the iron block from being inserted into the groove in this state, so that the rotating roller and the fork grass pole are in a static state, preventing the rotating roller and the fork grass pole from forcibly rotating with the round shaft and causing injury, when it is necessary to rotate the rotating roller and the fork grass pole again, the electromagnet is connected to a large current to significantly increase the magnetic force, then the electromagnet on the round shaft rotates to the iron block, at this time the increased magnetic force overcomes the resistance of the reset spring to the iron block, then the iron block is magnetically attracted into the groove, thereby reconnecting the shell and the round shaft, and then the round shaft rotates with the shell to continue rotating to restore the working state.

[0021] The utility model provides a kind of intelligent efficient continuous rice straw packing device, including: walking vehicle body 1, motor 2, rotating roller 3, fork grass pole 4, conveying belt 5, the fork grass pole 4 is provided with reminding structure, cleaning structure, the cleaning structure is used to remove the rice straw wound in the front end of fork grass pole 4, the reminding structure is used to remind when fork grass pole 4 occurs winding, the rotating roller 3 is composed of shell 6 and round shaft 7, and round shaft 7 rotates inside shell 6, the output end of motor 2 is fixedly connected with one end of round shaft 7, separating structure is arranged between shell 6 and round shaft 7, the separating structure is used to overload protection to motor 2, fork grass pole 4, lifting structure is provided in one end of rotating roller 3 of walking vehicle body 1, the lifting structure is used to lift fork grass pole 4 stuck in hole and make it normal work.

[0022] Wherein, the reminding structure includes the rectangular groove 8 that fork grass pole 4 sets, the inside of the rectangular groove 8 is provided with compression spring 9, the inside sliding connection of the rectangular groove 8 has a protection shell 10, and a protection shell 10 is connected with one end of compression spring 9, the side surface of fork grass pole 4 is installed in the rectangular groove 8 intermediate one press switch 11, the side wall of walking vehicle body 1 is installed with alarm 12, one press switch 11 is connected with alarm 12 by wire.

[0023] Specifically, a protection shell 10 isolates a press switch 11, which helps to prevent damage caused by the circular friction of rice straw on the press switch 11 when forking, and when the rice straw is wound around the front end of the fork grass pole 4, the protection shell 10 will be wrapped, and as the degree of winding increases, the protection shell 10 will move closer and closer, and the force exerted on the protection shell 10 will increase, causing the protection shell 10 to move towards the rectangular groove 8 and exert pressure on the compression spring 9, causing it to shorten. As the depth of the protection shell 10 moving in the rectangular groove 8 deepens, it will eventually press the press switch 11, causing the alarm 12 to be powered on and alarm. When the operator on the walking vehicle body 1 hears the alarm 12 ringing, it indicates that the fork grass pole 4 has been wound with rice straw. At this time, the operator can increase the current input to the motor 2 to increase its output speed. Higher speed will drive the rotating roller 3 and fork grass pole 4 to rotate faster, which will help the subsequent use of centrifugal force to drive the cleaning structure to work.

[0024] Further, the cleaning structure comprises a slide groove 13 arranged on the fork grass rod 4, the inside of the slide groove 13 is slidably connected with a movable block 14, the inside of the slide groove 13 is provided with a tension spring 23 connected with the movable block 14, the top of the movable block 14 is fixed with a blade 15 and a top rod 19, the bottom of the fork grass rod 4 is fixed with a second protective shell 16, and the second protective shell 16 wraps the movable block 14 and the blade 15, the top of the second protective shell 16 is hingedly connected with a protective plate 18 through a torsion spring hinge 17, and the cleaning structure further comprises a vertical groove 20, the vertical groove 20 is communicated with the slide groove 13, the bottom of the movable block 14 is fixed with a bent rod 21, and the bent rod 21 penetrates through the vertical groove 20 to the outside of the fork grass rod 4.

[0025] Specifically, in the initial state, that is, during normal operation, because the rotating speed of the motor 2 to the rotating roller 3 is low, the centrifugal force generated cannot overcome the resistance of the tension spring 23 to the movable block 14, so that the movable block 14 is in a static state under the normal feeding state, when the rotating speed increases to increase the centrifugal force of the fork grass rod 4, the centrifugal force generated at this time overcomes the resistance of the tension spring 23 to the movable block 14, and then the movable block 14 moves along the slide groove 13 and lengthens the tension spring 23, when the movable block 14 moves, the protective plate 18 is pried open through the top rod 19, and then the movable block 14 and the blade 15 are separated from the inside of the second protective shell 16, at this time, the purpose of cutting off the wrapped straw is achieved through the rapid movement of the blade 15, the purpose of the second protective shell 16 is to block the blade 15, prevent the blade 15 from being exposed and cutting off the straw during normal operation, the sealing ring arranged at the position where the protective plate 18 contacts the second protective shell 16 can prevent rainwater from entering and rusting the blade 15 in rainy days, when it is necessary to further cut the wrapped straw, at this time, the rotating speed of the motor 2 needs to be reduced, and then the centrifugal force decreases, the tension spring 23 resets with the movable block 14, and then acts on the protective plate 18 to make it rotate, and then the movable block 14 returns to the inside of the second protective shell 16, the torsion spring hinge 17 facilitates the reset of the protective plate 18 after rotating, the rotating speed of the motor 2 is increased again after the movable block 14 is reset, and then the centrifugal force increases, the movable block 14 repeats the above operation to further cut the straw, which can realize the automatic cleaning of the straw, without manual operation, improve the work efficiency, reduce the labor intensity of the operator, and improve the overall operation progress.

[0026] Further, the separation structure comprises a hollow block 22 fixed on the shell 6, the inside of the hollow block 22 is slidingly connected with an iron block 24 and is provided with a reset spring 25, one end of the iron block 24 is connected with the reset spring 25, the separation structure further comprises a groove 26 provided outside the round shaft 7, the bottom of the groove 26 is embedded with an electromagnet 27 magnetically matched with the iron block 24, the iron block 24 in the initial state is inserted into the groove 26 and is magnetically adsorbed by the electromagnet 27, the separation structure further comprises an arc-shaped slot 28 provided on the inner wall of the groove 26, the inside of the groove 26 is slidingly connected with a baffle 29 along the arc-shaped slot 28, the baffle 29 is connected with the slot wall of the groove 26 through a high-rigidity spring 30.

[0027] Specifically, when the grass prong 4 moves to the stone or the pit and cannot rotate, the torque of the motor 2 is increased to rotate the round shaft 7, the grass prong 4 on the rotating roller 3 cannot rotate, so that the rotating roller 3 and the iron block 24 are in a static state, the baffle 29 is blocked by the static iron block 24, and the high-rigidity spring 30 is compressed under the action of the large torque as the round shaft 7 continues to rotate, and then the iron block 24 comes to a position away from the electromagnet 27 in the groove 26, at this time, the iron block 24 is separated from the electromagnet 27, so the reset spring 25 resets the iron block 24 to retract from the groove 26 to the inside of the hollow block 22.

[0028] At this time, the shell 6 and the round shaft 7 are lack of connecting parts, so the motor 2 will idle with the round shaft 7, and the current of the electromagnet 27 at this time is not strong current, so the magnetic attraction to the iron block 24 is general, and therefore the electromagnet 27 will not magnetically attract the iron block 24 when the round shaft 7 idles, the purpose is to prevent the iron block 24 from being reinserted into the groove 26 in this state, so that the rotating roller 3 and the grass prong 4 are in a static state, and prevent the rotating roller 3 and the grass prong 4 from forcibly rotating with the round shaft 7 to cause injury.

[0029] When it is needed to rotate the rotating roller 3 and the grass prong 4 again, a large current is input into the electromagnet 27 to significantly increase the magnetic force, and then the electromagnet 27 on the round shaft 7 rotates to the iron block 24, at this time, the increased magnetic force overcomes the resistance of the reset spring 25 to the iron block 24, and then the iron block 24 is magnetically adsorbed into the inside of the groove 26, so that the shell 6 and the round shaft 7 are reconnected, and then the round shaft 7 rotates to continue rotating with the shell 6 to restore the working state.

[0030] Next, the lifting structure includes an electromagnetic slide rail 31 fixedly installed on one end of the rotating roller 3 close to the walking vehicle body 1 and the forked straw rod 4, an electromagnetic slide block 32 slidably fitted outside the electromagnetic slide rail 31, and a support block 33 fixedly connected to the electromagnetic slide block 32, wherein the motor 2 and the rotating roller 3 are installed on the support block 33, and the lifting structure further includes a cam 39 fixedly installed on one end of the circular shaft 7, and a support plate 34 of the shell 6, wherein a second pressing switch 35 is installed on the bottom of the support plate 34, the second pressing switch 35 is connected to the electromagnetic slide rail 31 and the electromagnetic slide block 32 through wires, and a complete control loop is formed, and a top plate 36 with damping is slidably connected to the side wall of the support plate 34, one end of the walking vehicle body 1 is provided with a linear groove 37, the linear groove 37 is slidably connected to a support rod 38, and the bottom end of the support rod 38 is fixedly connected to the support block 33.

[0031] Specifically, the idling of the circular shaft 7 indicates that the forked straw rod 4 is stuck, at this time, the idling of the circular shaft 7 drives the rotation of the cam 39, the cam 39 rotates to press the second pressing switch 35, the top plate 36 is provided with damping, so that after sliding, it is in a static state, which is beneficial to prevent the second pressing switch 35 from being pressed from being bounced off, for example, a rubber damping is arranged at the connection between the support plate 34 and the top plate 36, so that the subsequent descent can only be achieved by manual sliding, when the second pressing switch 35 is triggered (pressed), the circuit is closed, thereby connecting the power supply circuit of the electromagnetic slide rail 31 and the electromagnetic slide block 32, then the electromagnetic slide block 32 moves upward outside the electromagnetic slide rail 31, and the motor 2, the rotating roller 3 and the forked straw rod 4 are lifted, thereby making the forked straw rod 4 stuck in the pit leave the pit and get out of trouble, the automatic lifting is arranged, which is faster than manual lifting in response to the stuck fault, avoids the delay of manual operation, avoids the overloading and damage of the motor 2, the rotating roller 3 and the forked straw rod 4, and the weight of the motor 2, the rotating roller 3 and the forked straw rod 4 is heavy, so the electric lifting can save labor, and when resetting, the top plate 36 is manually pressed downward, so that the second pressing switch 35 is bounced off to make the electromagnetic slide rail 31 and the electromagnetic slide block 32 lose the magnetic locking force, and then the previously lifted components are reset manually.

[0032] Demonstratively, the automatic alarm winding, the automatic overload protection of the separation structure, and the automatic trouble getting out of the lifting structure realize intelligent fault identification and disposal without manual close observation, achieve the purpose of intelligence, the automatic cutting of the cleaning structure replaces manual work, the stuck problem is quickly handled by the separation and lifting structure, the operation rhythm is not dragged to achieve the purpose of high efficiency, and the winding and stuck problems can be solved immediately to ensure continuity.

[0033] Working principle: through the setting of the prompt structure, the first protective shell 10 will isolate the first press switch 11, which is conducive to preventing the cycle friction of the straw on the first press switch 11 from causing damage. When the straw is wound around the front end of the straw fork 4, it will wrap the first protective shell 10. As the degree of winding of the straw increases, it will become closer and closer, and then the force applied to the first protective shell 10 will become greater and greater, and will press the first protective shell 10 to move in the rectangular groove 8 and exert pressure on the compression spring 9 to make it shorter. As the depth of the movement of the first protective shell 10 in the rectangular groove 8 deepens, it will eventually press the first press switch 11 to make the alarm 12 energized and alarm.

[0034] When the operator on the walking vehicle 1 hears the alarm 12 ringing, it indicates that the straw fork 4 has been wound with straw. At this time, the operator can increase the current input to the motor 2 to increase its output speed. Higher speed will drive the rotating roller 3 and the straw fork 4 to rotate faster, which will help the subsequent use of centrifugal force to drive the cleaning structure to work.

[0035] It should be noted that since the middle straw fork 4 is in contact with the straw the most, it only needs to be set with a prompt structure, so this case only sets a prompt structure on the middle straw fork 4.

[0036] During the process of being rolled up by the straw fork 4, the fibers of the straw are easily hooked to the front end of the straw fork, especially in the case of high humidity of the straw, the winding phenomenon is more likely to occur. The prior art lacks an automatic cleaning structure for winding straw. When winding occurs, it can only be cleaned by manual operation, which reduces work efficiency, increases the labor intensity of the operator, and affects the overall operation progress. The present case solves this drawback by setting a cleaning structure, which is as follows: Through the cleaning structure provided by the present case, in the initial state, that is, during normal operation, since the speed of the motor 2 to the rotating roller 3 is low, the centrifugal force generated cannot overcome the resistance of the tension spring 23 to the movable block 14, so the movable block 14 in the normal feeding state is in a static state. When the winding of the straw is cleaned, the speed increases significantly, the centrifugal force on the straw fork 4 increases significantly, and the centrifugal force generated at this time overcomes the resistance of the tension spring 23 to the movable block 14, and then the movable block 14 moves along the sliding groove 13 and lengthens the tension spring 23. When the movable block 14 moves, the protective plate 18 is opened by the top rod 19, and then the movable block 14 and the blade 15 move out of the inside of the second protective shell 16. At this time, the purpose of cutting off the winding straw is achieved by the rapid movement of the blade 15. The purpose of the second protective shell 16 is to block the blade 15 to prevent the blade 15 from being exposed and cutting off the straw during normal operation. The position where the protective plate 18 contacts the second protective shell 16 is provided with a sealing ring, which can prevent rainwater from entering and rusting the blade 15 in rainy weather.

[0037] In addition, when the need to further cut the wrapped straw, at this time need to reduce the speed of motor 2 and then the centrifugal force decreases, the extension spring 23 reset with the movable block 14 down, and then act on the protective plate 18 to make it rotate, and then the movable block 14 comes back to the inside of the second protective shell 16, the torsional spring hinge 17 is reset after the protective plate 18 rotates, the movable block 14 is reset to increase the speed of the motor 2 again and then the centrifugal force increases, the movable block 14 repeats the above operation to further cut the straw, which can realize the automatic removal of the straw, without manual operation, improve work efficiency, reduce the labor intensity of the operator, and improve the overall operation progress.

[0038] When the forked straw rod 4 moves to the stone or into the pit (such as the pit hole on the cement ground for drying straw), it cannot be rotated. If it is continuously forced to rotate at this time, it will cause harm to the motor 2 and the forked straw rod 4. The separation structure is set to solve this drawback. Specifically: When the forked straw rod 4 is working normally, as shown in Figure 9 The iron block 24 is located inside the groove 26 and is magnetically attracted by the electromagnet 27. The magnetic attraction at this position is to prevent the iron block 24 from being retracted into the hollow block 22 by the reset spring 25, and to maintain the state of the iron block 24 inserted into the groove 26. The current size of the electromagnet 27 in this state is lower than the current size when the shell 6 and the forked straw rod 4 are reconnected. Therefore, the electromagnet 27 at this time can only attract the iron block 24 that has been inserted into the groove 26, but cannot attract the iron block 24 when the circular shaft 7 is idling. When the circular shaft 7 is idling, it can only be attracted by a large current, and then the purpose of "small current maintenance and large current attraction" is achieved.

[0039] The purpose is to stabilize the iron block 24 in the groove 26 during normal operation, and at this time the reset spring 25 in the hollow block 22 is in a stretched state. When the circular shaft 7 rotates, the iron block 24 is pressed by the baffle 29. Since the hollow block 22 on the iron block 24 is fixed with the shell 6, the rotation of the circular shaft 7 will cause the shell 6 and the forked straw rod 4 to rotate.

[0040] It needs to be explained that because the high stiffness spring 30 has high stiffness, the motor 2 needs to increase the torque to drive it to compress, so the baffle 29 is almost in a static state to press the iron block 24 under normal conditions.

[0041] When the fork grass rod 4 moves to the stone or into the pit and cannot rotate, the torque of the motor 2 increases to rotate the round shaft 7, and the fork grass rod 4 on the rotating roller 3 cannot rotate, so that the rotating roller 3 and the iron block 24 are in a static state, and the baffle 29 is blocked by the static iron block 24. With the continuous rotation of the round shaft 7, the high-rigidity spring 30 is compressed under the action of a large torque, and then the iron block 24 comes to the position away from the electromagnet 27 in the groove 26. At this time, the iron block 24 is separated from the electromagnet 27, so the reset spring 25 resets the iron block 24 to leave the groove 26 and retract into the hollow block 22.

[0042] At this time, the shell 6 and the round shaft 7 are not connected due to the lack of connecting parts, so the motor 2 rotates with the round shaft 7. At this time, the current of the electromagnet 27 is not a strong current, so the magnetic attraction to the iron block 24 is general. Therefore, the electromagnet 27 will not magnetically attract the iron block 24 when the round shaft 7 is idling. The purpose is to prevent the iron block 24 from being reinserted into the groove 26 in this state, so that the rotating roller 3 and the fork grass rod 4 are in a static state, and prevent the rotating roller 3 and the fork grass rod 4 from forcibly rotating with the round shaft 7 to cause injury.

[0043] When it is necessary to rotate the rotating roller 3 and the fork grass rod 4 again, a large current is supplied to the electromagnet 27 to significantly increase the magnetic force. Then, when the electromagnet 27 on the round shaft 7 rotates to the iron block 24, the increased magnetic force overcomes the resistance of the reset spring 25 to the iron block 24. Then, the iron block 24 is magnetically attracted into the groove 26, thereby reconnecting the shell 6 and the round shaft 7. Then, the round shaft 7 rotates to continue rotating with the shell 6 to restore the working state.

[0044] It needs to be explained that the power transmission path is quickly cut off at the moment when the torque of the motor 2 abnormally increases (i.e. the initial stage of overload occurs). This process responds in time relative to human operation, and the response is extremely fast. The load of the motor 2 is instantaneously removed, thereby avoiding the risk of damage such as winding overheating and current overload caused by the motor 2 being in a locked-rotor or large-torque overload state for a long time, effectively protecting the motor 2. At the same time, the fork grass rod 4 will instantaneously stop rotating when it is stuck in a pit or a stone, thereby avoiding bending, deformation or even breaking of the fork grass rod 4.

[0045] Through the lifting structure, the idling of the round shaft 7 indicates that the fork grass rod 4 is stuck. At this time, the round shaft 7 idles with the cam 39 rotating, the cam 39 rotates to press the second pressing switch 35 on the top plate 36. The top plate 36 is provided with damping, so that after sliding, it is in a static state, which is conducive to preventing the second pressing switch 35 from being popped open after being pressed. For example, rubber damping is provided at the connection between the support plate 34 and the top plate 36, so that subsequent descent can only be achieved by human sliding.

[0046] When the second press switch 35 is triggered (pressed), the circuit is closed, thereby turning on the power supply circuit of the electromagnetic slide rail 31 and the electromagnetic slide block 32, and then the electromagnetic slide block 32 moves upward outside the electromagnetic slide rail 31, and the motor 2, the rotating roller 3 and the fork grass rod 4 are lifted, thereby making the fork grass rod 4 stuck in the pit leave the pit hole and get rid of the trouble, and the automatic lifting is set to be relative to the artificial lifting, the stuck fault can be quickly responded, the delay of the artificial operation is avoided, the motor 2, the rotating roller 3 and the fork grass rod 4 are prevented from being damaged due to overload, and the motor 2, the rotating roller 3 and the fork grass rod 4 are three-in-one, and the weight is heavy, so the electric lifting can save labor.

[0047] When the reset, the top plate 36 is manually pressed downward, the second press switch 35 is opened, the electromagnetic slide rail 31 and the electromagnetic slide block 32 are powered off and lose the magnetic locking force, and then the previously lifted components are reset by manually pressing downward.

[0048] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
