Description

Technical Field

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

[0002] In the field of agricultural production, the storage and transportation of materials such as straw bales are important links. With the large-scale development of agriculture, large quantities of straw bales and other materials often need to be stacked in warehouses. When it comes to the handling and transportation of straw bales and other materials, especially for warehouses with large storage spaces, manual handling of straw bales and other materials from deep inside the warehouse to the outbound point or from the inbound point to the designated stacking area in the warehouse is extremely inefficient and labor-intensive, making it difficult to meet the needs of large-scale operations. While 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 transportation efficiency is still far from the ideal state. In view of this, chain conveyors capable of long-distance transportation are generally reasonably arranged and installed inside the warehouse to achieve long-distance transportation of straw bales and other materials. Chain conveyors, with their unique structure and operating characteristics, can stably and continuously transport materials such as bales of straw over long distances along a preset path, effectively avoiding the many drawbacks of manual and mobile equipment handling mentioned above. However, there are still some significant shortcomings in the actual application of chain conveyors, as shown below:

[0003] (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 staff being unable to keenly perceive the abnormal operation of the chain conveyor in the first place. In the actual production operation environment, the information lag may trigger a series of chain reactions;

[0004] (2) During the operation of the chain conveyor, it is common sense that there should be a dedicated person in charge to monitor the equipment in real time, so that the person can quickly know and take countermeasures at the moment of sudden failure. However, under the 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. In this way, when the chain conveyor unfortunately fails, the failure cannot be handled in a timely manner due to the absence of the responsible personnel;

[0005] (3) When using a chain conveyor to transport materials such as straw bundles, 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 cannot 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 conveying operation, thereby increasing the risk factor during the operation of the chain conveyor, reducing the service life and overall operating efficiency of the equipment, and is not conducive to achieving the goal of efficient and safe material conveying operations.

[0016] The beneficial effects of the agricultural straw long-distance transport device of the present invention are as follows:

[0017] (1) The present invention embeds a matching induction sheet on the chain plate of the chain conveyor and sets a corresponding conveying frequency induction component, so that during the normal operation of the chain 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 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 established 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 will be warned in the first time, prompting the staff to quickly take the shutdown maintenance operation for the faulty chain conveyor, 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;

[0018] (2) The present invention effectively limits the standing position of personnel who are responsible for observing when the chain conveyor is in operation through the setting of the base structure. Specifically, when the staff stands on the pressure plate, their own weight will produce a downward pressure, and 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 induction block and the induction installation groove changes. Based on this position change, the matching induction block is separated from the induction area range of the standing position induction component. When the staff 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 relevant linkage components will move synchronously, thereby again The relative position relationship between the matching induction block and the induction mounting slot is changed so that the matching induction block is moved back into the induction range of the station induction component. Once the matching induction block enters the induction range of the station 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 activation of the buzzer alarm. The high-decibel buzzer of the buzzer alarm will attract the attention of the staff who are currently leaving, and serve as a warning to them, reminding them not to leave the surrounding area of ​​the chain conveyor at will during the operation of the chain conveyor, 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 absence of personnel.

[0019] (3) The present invention can adjust the position of the bales of straw accurately and synchronously according to the specific starting and placing points of the bales of straw by using a movable block that can be flexibly moved and adjusted along the chain conveyor. When placing the bales of straw, the first group of bales of 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 perform synchronous 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 bales of straw can be accurately coordinated and controlled, thereby ensuring that the distance between the two groups of bales of 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 bales of straw too close to each other, and ensuring the smooth and efficient operation of the chain conveyor during the entire material transportation process.

The station sensing component 2012 adopts a proximity switch, and the sensing end of the station sensing component 2012 Towards the rear side; a through socket 2011 that passes through the bottom surface of the base 2 is opened on the rear side of the inner bottom surface of the sensing mounting groove 206; a plug block 209 is fixedly installed on the bottom surface of the pressure plate 202 relative to the through socket 2011, and a matching sensing block 2010 is fixedly installed on the bottom surface of the plug block 209. The plug block 209 and the matching sensing block 2010 are both slidably plugged into the through socket 2011; in the natural state of the return spring 207, the matching sensing block 2010 corresponds to the position of the sensing mounting groove 206. At this time, the matching sensing block 2010 is within the sensing range of the position sensing component 2012; the monitoring The right end face of the control mating block 102 is also equipped with a buzzer alarm 103 electrically connected to the microcontroller 107; when the position sensing component 2012 senses the mating sensing block 2010, the position sensing component 2012 feedbacks a signal to the microcontroller 107, and the microcontroller 107 controls the buzzer alarm 103 to start; when the bottom end face of the pressure plate 202 is in contact with the top face of the support block 205, the mating sensing block 2010 is staggered with the sensing mounting slot 206, and the mating sensing block 2010 is out of the sensing range of the position sensing component 2012, and the reset spring 207 is in a compressed state.

[0037] The working process and usage of the embodiment of the agricultural straw long-distance transport device of the present invention are as follows:

[0038] 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 ending point of the straw transport, so that the position of the movable block 302 corresponds to the starting and ending point of the straw transport;

[0039] 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 is one second longer than the time from the previous matching induction piece 101 leaving the induction range of the conveying frequency induction component 201 to the next matching induction piece 101 reaching the induction range when the chain conveyor 1 is in the starting state, when the conveying frequency of the chain conveyor 1 remains normal, under the normal operation of the chain conveyor 1, the matching induction piece 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 piece 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 or slow down, the matching induction piece 101 embedded in the 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 feeds back 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 the chain conveyor 1 for maintenance, 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 the equipment.

[0040] According to regulations, when the chain conveyor 1 is running, 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 the machine is shut down for maintenance. The present application implements a standing position restriction for the staff responsible for the chain conveyor 1 by setting up 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 running, 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 surface of the support block 205. At this time, the return spring 207 is in a compressed state, and the position of the cooperative sensing block 2010 is staggered with the position of the sensing installation groove 206. The cooperative sensing block 2010 is out of the sensing range of the standing sensing component 2012. 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. The synchronous insertion 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. The matching sensing block 2010 is within the sensing range of the standing position sensing component 2012. When the standing position sensing component 2012 senses the matching sensing block 2010, it will give a feedback signal to the microcontroller 107, and the microcontroller 107 will control the buzzer alarm 103 to start, thereby using the high-decibel buzzer of the buzzer alarm 103 to warn the operator who is currently leaving, reminding him not to leave the vicinity of the chain conveyor 1 during the operation of the chain conveyor 1.

[0041] For the transportation of bales of straw, mobile equipment such as a forklift or a crane equipped with a straw grab can be used to lift the bales of straw and move them to the starting and placing point for the transportation of the bales of straw, and then place the bales of straw on the chain of the chain conveyor 1, so as 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 feedbacks a signal to the microcontroller 107, and 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. Therefore, before the feedback signal from 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 from 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 in the extended state. The top surface of 06 is higher than the top surface of the chain conveyor 1. Through the setting of the blocking block 306, before the piston rod of the electric cylinder 305 is retracted, the blocking block 306 higher than the top surface of the chain conveyor 1 will hinder the operation of the equipment for transporting bundles of straw to place the bundles of straw on the chain of the chain conveyor 1, and it is impossible to perform the corresponding operation of placing the bundles of straw. The timing value of the timing module b106 of the present invention, when the chain conveyor 1 is in the starting state, its timing duration is consistent with the time required for transporting the first group of bundles of straw placed at the starting point to the position suitable for placing the next group of bundles of straw at the starting point. 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. 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 occurrence of an operating burden on the chain conveyor 1 caused by the distance between multiple groups of bales of straw being placed too close.
