Description

Technical Field

[0001] The invention relates to the technical field of long-distance transportation of agricultural materials, and in particular to a long-distance transportation device for agricultural straws. Background Art

[0002] In the field of agricultural production, the storage and transportation of materials such as bales of straw is an important link. With the large-scale development of agriculture, a large number of bales of straw and other materials often need to be stacked in warehouses. As for the handling and transportation of materials such as bales of straw, especially for warehouses with large storage space, the manual handling efficiency is extremely low and the labor intensity is high when transporting bales of straw and other materials from the depths of the warehouse to the outbound point or from the inbound point to the designated stacking area in the warehouse, which is difficult to meet the needs of large-scale operations. Although the use of mobile equipment such as forklifts and cranes equipped with straw grabs for transportation reduces the manpower burden, the equipment consumes a lot of energy during operation, and the actual handling efficiency is still far from the ideal state. In view of this, the warehouse is generally reasonably arranged and installed with chain conveyors that can realize long-distance transportation functions, so as to realize the long-distance transportation of bales of straw and other materials. With its unique structure and operating characteristics, the chain conveyor can stably and continuously transport materials such as bundles of straw over long distances along a preset path, effectively avoiding the many disadvantages of manual handling and mobile equipment handling mentioned above. However, there are still some significant shortcomings in the actual application of the chain conveyor, as shown below: (1) During the operation of the chain conveyor, when a fault occurs and the conveying frequency is reduced and the operating speed slows down, due to the lack of a corresponding monitoring mechanism, this key information cannot be captured and fed back in time at the key node where the conveying frequency changes abnormally. This directly leads to the inability of the staff to keenly perceive the abnormal operation of the chain conveyor in the first place, which may trigger a series of chain reactions in the actual production environment due to the lag of this information; (2) During the operation of the chain conveyor, it is common sense that there should be a dedicated person in charge to conduct real-time monitoring on one side of the equipment, so that the person can quickly know and take countermeasures when a fault occurs. However, under current technical conditions, it is difficult to effectively restrict and manage the position of the responsible personnel. This means that the responsible personnel may leave their posts without authorization due to various subjective or objective reasons. Once the responsible personnel leave, there is no way to provide them with timely and effective warnings in the existing mechanism. As a result, when the chain conveyor unfortunately fails, the failure cannot be handled in a timely manner due to the absence of the responsible personnel; (3) When using a chain conveyor to transport bales of straw and other materials, in order to ensure that the chain conveyor can operate smoothly and efficiently, a specific spacing distance must be maintained between the materials. If excessive materials are placed in the same position, the operating burden of the chain conveyor will be greatly increased, which may lead to serious problems such as equipment overload, chain jamming, and motor burnout. However, the existing chain conveyor technology has obvious shortcomings in controlling the material placement interval, and it is impossible to effectively limit and regulate the material placement interval. This makes it difficult to ensure the rationality and stability of the material interval during the actual material transportation operation, thereby increasing the risk factor during the operation of the chain conveyor, reducing the service life of the equipment and the overall operating efficiency, and is not conducive to achieving the goal of efficient and safe material transportation operations. Summary of the invention

When the chain conveyor is in the starting state, the timing value of the timing module b is consistent with the time required for transporting the first group of straw bales placed at the starting point to a position suitable for placing the next group of straw bales at the starting point, so as to ensure that the spacing between the two groups of straw bales can ensure the normal operation of the chain conveyor without causing any operating burden on it.

[0012] Preferably, a buzzer alarm electrically connected to the microcontroller is also installed on the right end face of the monitoring mating block; when the position sensing component senses the mating sensing block, the position sensing component feedbacks a signal to the microcontroller, and the microcontroller controls the buzzer alarm to start; when the bottom end face of the pressure plate is in a fit with the top end face of the supporting block, the mating sensing block is offset from the sensing mounting slot, and the mating sensing block is out of the sensing range of the position sensing component, while the reset spring is in a compressed state.

[0013] The beneficial effects of the agricultural straw long-distance transport device of the present invention are as follows: (1) The present invention embeds a matching induction sheet on the chain plate of the chain plate conveyor and sets a corresponding conveying frequency induction component, so that during the normal operation of the chain plate conveyor, as the chain plate continues to move, the matching induction sheet will interact with the conveying frequency induction component according to a specific rule, thereby realizing real-time and accurate monitoring of the conveying frequency. Once the chain plate conveyor has an internal mechanical failure, abnormal power transmission or other potential problems that cause the conveying frequency to decrease and the operating speed to slow down, the moving speed of the chain plate will also slow down. In this way, within the predetermined timing module a timing cycle, there will be no The method is to timely reset the timing value of the timing module a by relying on the inductive feedback of the conveying frequency sensing component and the matching sensing piece as in normal operation. Therefore, when the timing of the timing module a reaches the preset value, the feedback signal will be triggered immediately, and the signal will synchronously start the sound and light alarm. Based on the alarm of the sound and light alarm, the staff can be warned in the first time, prompting the staff to quickly shut down the faulty chain conveyor for maintenance, so as to effectively avoid the chain conveyor from suffering more serious damage due to the failure not being handled in time, and ensure the safe and stable operation of the chain conveyor; (2) The present invention effectively limits the standing position of personnel who are responsible for observing when the chain conveyor is in operation by setting a base structure. Specifically, when a worker stands on the pressure plate, his own weight will produce a downward pressure. When the pressure plate is displaced by force, it will drive the components connected to it to move in coordination, so that the relative position between the matching sensing block and the sensing mounting groove changes. Based on this position change, the matching sensing block is separated from the sensing area of ​​the standing position sensing component. When the worker responsible for the chain conveyor leaves the pressure plate for some reason, the reset spring that was compressed during the previous downward pressure of the pressure plate loses its pressure restraint and will perform a reset rebound operation according to its own elastic characteristics. Driven by the rebound force of the reset spring, the related linkage components will move synchronously, thereby again The relative position relationship between the matching induction block and the induction installation slot is changed so that the matching induction block is moved back into the induction range of the position induction component. Once the matching induction block enters the induction range of the position induction component, an induction feedback signal will be quickly generated between the two. Based on this induction feedback signal, the system will immediately control the buzzer alarm to start, and the high-decibel buzz of the buzzer alarm will attract the attention of the staff who are currently leaving, which will serve as a warning and reminder to the staff. During the operation of the chain conveyor, they must not leave the surrounding area of ​​the chain conveyor at will, thereby strictly implementing the position restriction of the staff, greatly improving the safety and standardized management level during the operation of the chain conveyor, and effectively avoiding various safety hazards and production accidents that may be caused by unauthorized departure of personnel; (3) The present invention can accurately adjust the synchronous position according to the specific starting and placing point of the bundled straw through the movable block that can be flexibly moved and adjusted along the chain conveyor. When placing the bundled straw, the first group of bundled straw can be placed smoothly and accurately on the predetermined position of the chain conveyor through the induction and delayed feedback of the distance sensor. Subsequently, based on the delayed feedback of the distance sensor, the telescopic movement of the piston rod of the electric cylinder is controlled to dynamically adjust the height position of the blocking block, and the timing module b is controlled to synchronize the timing, thereby realizing automatic adjustment of the height position of the blocking block. Through this series of coordinated operations, the placement time node of the next group of bundled straw can be accurately coordinated and controlled, thereby ensuring that the distance between the two groups of bundled straw is always within a reasonable range, ensuring the normal operation of the chain conveyor, avoiding the operation burden on the chain conveyor caused by the placement of multiple groups of bundled straw too close, and ensuring the smooth and efficient operation of the chain conveyor during the entire material transportation process.

[0019] The working process and use of the agricultural straw long-distance transport device of the present invention are as follows: When it is necessary to transport the bundles of straw stacked in the warehouse out of the warehouse or transport the bundles of straw into the warehouse over a long distance, the staff can first adjust the position of the movable block 302 by sliding the limit slider 303 and the limit slide groove 301 along the mounting block 3 according to the starting and placing point of the straw bale transportation, so that the position of the movable block 302 corresponds to the starting and placing point of the straw bale transportation; During transportation application, after the staff controls the chain conveyor 1 to start running, the timing module a105 starts synchronously. Because the timing value of the timing module a105 of the present invention, when the chain conveyor 1 is in the starting state, is one second longer than the time from the previous matching induction sheet 101 leaving the induction range of the conveying frequency induction component 201 to the next matching induction sheet 101 reaching the induction range, when the chain conveyor 1 is in the starting state, when the conveying frequency of the chain conveyor 1 is kept in a normal state, under the normal operation of the chain conveyor 1, the matching induction sheet 101 embedded in its chain plate will reach the induction range of the conveying frequency induction component 201 before reaching the timing value of the timing module a105, and when the conveying frequency induction component 201 senses the matching induction sheet 101, the conveying frequency induction component 201 feedbacks a signal to the microcontroller 107, and the microcontroller 107 controls the timing module a105. 5 The timing is reset to avoid false alarms. Based on this design, when the chain conveyor 1 fails, causing its conveying frequency to decrease and slow down, the matching induction sheet 101 embedded in its chain plate will fail to reach the sensing range of the conveying frequency sensing component 201 in time before reaching the timing value of the timing module a105. When the timing value of the timing module a105 is reached, the timing module a105 feedbacks a signal to the microcontroller 107, and the microcontroller 107 controls the sound and light alarm 104 to start, thereby warning the staff through the sound and light alarm of the sound and light alarm 104, prompting the staff to quickly shut down and repair the failed chain conveyor 1, thereby effectively avoiding the chain conveyor 1 from suffering more serious damage due to the failure not being handled in time, and effectively ensuring the normal order of transportation operations and the safe and stable operation of equipment; According to regulations, when the chain conveyor 1 is in operation, it is necessary to ensure that there are staff around it to ensure that when the chain conveyor 1 fails, it is discovered in time and shut down for maintenance. The present application implements position restriction for the staff responsible for the chain conveyor 1 by setting the right half area of ​​the base 2 (the space size of the area can be set according to actual space requirements), so that when the chain conveyor 1 is in operation, the staff responsible for the chain conveyor 1 can stand in the right half area of ​​the base 2, and they will stand on the pressure plate 202. Under the pressure of the staff's body weight, the pressure plate 202 moves downward along the pressure groove 204 until the bottom end surface of the pressure plate 202 is in contact with the top end surface of the support block 205. At this time, the reset spring 207 is in a compressed state, and the position of the cooperative induction block 2010 is staggered with the position of the induction installation groove 206. The cooperative induction block 2010 is out of the sensing range of the standing sensing component 212. Based on this design, when the staff responsible for the chain conveyor 1 When the operator leaves the right half of the base 2 (i.e., leaves the pressure plate 202), the return spring 207 in the compressed state quickly returns to its original position without the weight pressure of the operator, thereby pushing the pressure plate 202 to move upward along the pressure groove 204, and the synchronous plug block 209 and the matching sensing block 2010 will also move upward along the through socket 2011. When the return spring 207 rebounds and returns to its original position, the matching sensing block 2010 corresponds to the position of the sensing installation groove 206, and the matching sensing block 2010 is within the sensing range of the position sensing component 2012. When the position sensing component 2012 senses the matching sensing block 2010, it gives a feedback signal to the microcontroller 107, and the microcontroller 107 controls the buzzer alarm 103 to start, thereby using the high-decibel buzzer of the buzzer alarm 103 to warn the operator who has left the current position, reminding him not to leave the vicinity of the chain conveyor 1 during the operation of the chain conveyor 1. For the transportation of bales of straw, mobile equipment such as forklifts and cranes equipped with straw grabs can be used to lift the bales of straw and move them to the starting and placing points for the transportation of bales of straw, and then the bales of straw can be placed on the chain plates of the chain conveyor 1 to facilitate the long-distance transportation of the bales of straw. When the equipment for transporting the bales of straw moves to the sensing range of the distance sensor 304, the distance sensor 304 feeds back a signal to the microcontroller 107. The distance sensor 304 of the present invention is provided with a trigger delay time, and the trigger delay time is the same as the time when the equipment for transporting the bales of straw places the bales of straw on the chain conveyor 1. Therefore, before the feedback signal of the distance sensor 304 is given to the microcontroller 107, there is enough time for the equipment for transporting the bundled straw to place the bundled straw on the chain plate of the chain conveyor 1 and move away from the sensing range of the distance sensor 304. After the feedback signal of the distance sensor 304 is given to the microcontroller 107, the microcontroller 107 controls the timing module b106 to start the timing, and at the same time controls the piston rod of the electric cylinder 305 to extend. When the piston rod of the electric cylinder 305 is in the extended state, the blocking block 306 is 06, the top surface is higher than the top surface of the chain conveyor 1. By setting the blocking block 306, before the piston rod of the electric cylinder 305 is stored, the blocking block 306 higher than the top surface of the chain conveyor 1 will hinder the operation of the equipment for transporting bales of straw to place the bales of straw on the chain of the chain conveyor 1, and it is impossible to perform the corresponding bale placement operation. The timing value of the timing module b106 of the present invention, when the chain conveyor 1 is in the starting state, is consistent with the time required for transporting the first group of bales of straw placed at the starting point to the position at the starting point suitable for placing the next group of bales of straw. Therefore, when the timing value of the timing module b106 is reached, the timing module b106 feeds back a signal to the microcontroller 107, and the microcontroller 107 controls the piston rod of the electric cylinder 305 to retract. At this time, without the obstruction of the blocking block 306, the equipment for transporting bales of straw can place the transported bales of straw on the chain of the chain conveyor 1, and based on the time difference timed by the timing module b106, it can be ensured that the distance between the two groups of bales of straw placed can ensure the normal operation of the chain conveyor 1, avoiding the operation burden on the chain conveyor 1 caused by the close placement of multiple groups of bales of straw.
