Description

Technical Field

[0001] The utility model relates to the technical field of storage mechanisms, in particular to a full - bin alarm device for a storage mechanism of a harvester. Background Technique

[0002] The full - bin alarm device of a storage mechanism is an important safety device, which is used to automatically give an alarm when the bin or granary is full, so as to prevent overflow accidents or other related accidents caused by over - load storage.

[0003] In the prior art, when a harvester harvests materials, it continuously sends the materials into a storage barrel to collect the harvested materials. As the materials entering the storage barrel keep piling up and rising, it may cause overflow. Therefore, operators need to continuously observe the situation inside the storage barrel and then adjust the harvesting speed of the harvester. However, through the above - mentioned operation method, not only is human resources wasted, and multiple operators are required to cooperate to complete it, but also the harvesting efficiency of the harvester is reduced. In addition, by the way of the operator penetrating the materials in the storage barrel, overflow may occur due to untimely operation, which further increases the trouble. Content of the Utility Model

[0004] The purpose of the utility model is to provide a full - bin alarm device for a storage mechanism of a harvester to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A full - bin alarm device for a storage mechanism of a harvester, including: a mounting rod, on the upper surface of which a storage barrel is fixedly connected, on one side of the storage barrel, a light projector is fixedly installed, and on the other side of the storage barrel, a light receiver is fixedly installed.

[0006] Above the light receiver, there is a pressure plate, on the upper surface of the pressure plate, a sliding rod is fixedly connected, outside the sliding rod, a spring is sleeved, above the spring, there is a pressure ring, the upper surface of the pressure ring abuts against a pressure - sensitive resistor, the upper surface of the pressure - sensitive resistor is fixedly connected with a pressing plate, on one side of the pressing plate, an alarm is fixedly installed, and on one side of the alarm, there is a controller.

[0007] Preferably, the lower surfaces of the alarm and the controller are both fixedly connected with the pressing plate, the bottom of the spring is fixedly connected with the pressure plate, and the top of the spring is fixedly connected with the pressure ring.

[0008] Preferably, on the upper surface of the pressing plate, a limiting sleeve is fixedly installed, the sliding rod is slidably sleeved in the limiting sleeve, and at the top of the sliding rod, a limiting ring is fixedly sleeved.

[0009] Preferably, the light projector, the light receiver, and the alarm are all electrically connected with the controller.

[0010] Preferably, on one side of the mounting rod, there is a sealing plug, which is threadedly connected with the storage barrel, and on the outer circumferential surface of the storage barrel, a feed pipe is fixedly sleeved.

[0011] Preferably, fixed frames are fixedly connected to both sides of the top of the storage barrel. A threaded rod is rotatably sleeved in the fixed frame. A threaded sleeve is sleeved on the threaded rod, and a connecting seat is arranged on the lower side of the threaded sleeve.

[0012] Preferably, the lower surface of the connecting seat is fixedly connected to the pressing plate. One end of the connecting rod is rotatably connected to the connecting seat through a pin shaft, and the other end of the connecting rod is rotatably connected to the threaded sleeve through a pin shaft.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: First, start the light projector and the light receiver in advance. Fix the storage barrel on the harvester through the mounting rod. The harvester transports materials into the storage barrel through the feed pipe. As the materials continue to accumulate, the height of the materials in the storage barrel gradually rises. When the height of the accumulated materials is higher than the installation positions of the light projector and the light receiver and the highest position of the maximum volume of the storage barrel, the light receiver senses that the opposite light beam is cut off. At this time, the controller will turn off the light projector and start the alarm to sound an alarm, thus reminding the operator that the storage barrel is about to be full. Immediately afterwards, the operator can stop the harvesting operation of the harvester, thereby initially preventing the materials from overflowing. After the remaining materials in the feed pipe enter the storage barrel, at this time, by moving the pressing plate downward, the pressing plate for materials is indirectly driven to abut against the top of the materials. As the pressing plate continues to move downward, the piezoresistor drives the pressure ring to move downward. The pressure ring squeezes the spring, and the spring thus squeezes the pressing plate for materials, and the pressing plate for materials thus moves downward, thereby squeezing the materials and reducing the overall height of the materials, further preventing the storage barrel from being full, further avoiding the need for multiple people to cooperate to complete the operation, reducing the waste of human resources, and improving the harvesting efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to clearly and completely describe the purpose, technical solution of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0020] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: a full - bin alarm device for a storage mechanism of a harvester, including: a mounting rod 1, a storage barrel 2 is fixedly connected to the upper surface of the mounting rod 1, a light projector 3 is fixedly installed on one side of the storage barrel 2, a light receiver 4 is fixedly installed on the other side of the storage barrel 2, a pressure plate 5 is arranged above the light receiver 4, a sliding rod 6 is fixedly connected to the upper surface of the pressure plate 5, a spring 7 is sleeved outside the sliding rod 6, a pressure ring 8 is arranged above the spring 7, the upper surface of the pressure ring 8 abuts against a pressure - sensitive resistor 9, the upper surface of the pressure - sensitive resistor 9 is fixedly connected to a pressing plate 10, an alarm 11 is fixedly installed on one side of the pressing plate 10, and a controller 12 is arranged on one side of the alarm 11.

[0021] First, start the light projector 3 and the light receiver 4. Fix the storage barrel 2 on the harvester through the mounting rod 1. The harvester transports materials into the storage barrel 2 through a feed pipe 16. As the materials continue to accumulate, the height of the materials in the storage barrel 2 gradually rises. When the height of the accumulated materials is higher than the installation positions of the light projector 3 and the light receiver 4 and the maximum volume height of the storage barrel 2, the light receiver 4 senses that the opposed - beam light is cut off. At this time, the controller 12 will turn off the light projector 3 and start the alarm 11 to send an alarm, thus reminding the operator that the storage barrel 2 is about to be full. Then the operator can immediately stop the harvesting operation of the harvester, thus initially avoiding the overflow of materials. After the remaining materials in the feed pipe 16 enter the storage barrel 2, at this time, by moving the pressing plate 10 downward, the pressure plate 5 is indirectly driven to abut against the top of the materials. As the pressing plate 10 continues to move downward, the pressure - sensitive resistor 9 drives the pressure ring 8 to move downward. The pressure ring 8 compresses the spring 7, and the spring 7 thus compresses the pressure plate 5, and the pressure plate 5 thus moves downward, thereby squeezing the materials and reducing the overall height of the materials, and further avoiding the full - bin of materials.

[0022] Embodiment 2: On the basis of Embodiment 1, the lower surfaces of the alarm 11 and the controller 12 are fixedly connected to the pressing plate 10. The bottom of the spring 7 is fixedly connected to the pressure plate 5, and the top of the spring 7 is fixedly connected to the pressure ring 8. The alarm 11 and the controller 12 are fixedly installed on both sides of the upper surface of the pressing plate 10. The spring 7 is fixedly connected between the pressure plate 5 and the pressure ring 8, so as to play a buffering role on the pressure plate 5. A limit sleeve 13 is fixedly installed on the upper surface of the pressing plate 10. The sliding rod 6 is slidably sleeved in the limit sleeve 13. A limit ring 14 is fixedly sleeved on the top of the sliding rod 6. The limit sleeve 13 fixedly installed on the pressing plate 10 limits the sliding of the sliding rod 6, and the limit ring 14 fixedly sleeved on the top of the sliding rod 6 limits the sliding rod 6. The light projector 3, the light receiver 4, and the alarm 11 are all electrically connected to the controller 12.

[0023] The installation positions of the light projector 3 and the light receiver 4 are near the maximum volume height of the storage barrel 2. The light projector 3 and the light receiver 4 are used as input signals and are connected to the input end of the controller 12. The alarm 11 is used as an output device and is connected to the output end of the controller 12. After the material harvested by the harvester enters the storage barrel 2 from the feed pipe 16, as the harvester continues to harvest, the material entering the storage barrel 2 increases, so the height of the material increases accordingly. When the height of the material is higher than the positions of the light projector 3 and the light receiver 4, the light receiver 4 senses that the opposed light beam is cut off, and this signal is transmitted to the controller 12. The controller 12 immediately activates the alarm 11 to give an alarm. At the same time, regarding the light projector 3, for subsequent use, the alarm 11 can remind the operator to immediately stop the harvesting operation of the harvester, avoiding excessive material from entering the storage barrel 2, thereby avoiding the occurrence of full - bin overflow or other related accidents in the storage barrel 2.

[0024] Embodiment 3: On the basis of Embodiment 2, a sealing plug 15 is provided on one side of the mounting rod 1. The sealing plug 15 is threadedly connected to the storage barrel 2. An inlet pipe 16 is fixedly sleeved on the outer circumferential surface of the storage barrel 2. The sealing plug 15 is threadedly connected to the bottom of the storage barrel 2, which facilitates the sealing and material taking of the storage barrel 2. The inlet pipe 16 is fixedly sleeved on the outer circumferential surface of the storage barrel 2, which facilitates the entry of materials. Fixed frames 17 are fixedly connected to both sides of the top of the storage barrel 2. A threaded rod 18 is rotatably sleeved in the fixed frames 17. A threaded sleeve 19 is sleeved on the threaded rod 18. A connecting seat 20 is provided on the lower side of the threaded sleeve 19. The fixed frames 17 are fixedly installed on both sides of the top of the storage barrel 2. The fixed frames 17 stably support the threaded rod 18. Two sections of threads with opposite helix directions are provided on the threaded rod 18. A set of two threaded sleeves 19 are symmetrically sleeved on the threaded rod 18. The lower surface of the connecting seat 20 is fixedly connected to the pressing plate 10. One end of the connecting rod 21 is rotatably connected to the connecting seat 20 through a pin shaft 22. The other end of the connecting rod 21 is rotatably connected to the threaded sleeve 19 through a pin shaft 22. The connecting seat 20 is fixedly installed on the upper surface of the pressing plate 10, which facilitates driving the pressing plate 10 to move. The connection between the connecting seat 20 and the threaded sleeve 19 is driven by the connecting rod 21 and the pin shaft 22.

[0025] When the harvesting operation of the harvester stops and the remaining materials in the inlet pipe 16 enter the storage barrel 2, one end of the threaded rod 18 is fixedly connected to the output end of the motor. The motor and the controller 12 are electrically connected. The motor is fixedly installed on one side of the fixed frame 17. By starting the motor, the motor drives the threaded rod 18 fixedly connected to its output end to rotate. The threaded rod 18 thus drives the threaded sleeves 19 sleeved thereon to move towards each other. Thus, one end of the connecting rod 21 is driven to move by the connection of the threaded sleeve 19 through the pin shaft 22, and the other end of the connecting rod 21 drives the connecting seat 20 to move downward through the connection of the pin shaft 22. The connecting seat 20 thus drives the pressing plate 10 to move downward. A pressure-sensitive resistor 9 is fixedly connected to the bottom of the pressing plate 10. The pressure-sensitive resistor 9 is fixedly connected through the spring 7, the pressure ring 8, and the pressing plate 5, so that the pressing plate 5 abuts against the top materials in the storage barrel 2. As the pressing plate 10 continues to press downward, the pressing plate 5 presses the materials downward, which is beneficial to reducing the height of the materials in the storage barrel 2. At the same time, when the materials are compacted, they will squeeze the pressing plate 5, causing the pressing plate 5 to move upward. Thus, the pressing plate 5 will drive the sliding rod 6 to slide upward in the limit sleeve 13. The spring 7 thus generates a reverse elastic force. The spring 7 will squeeze the pressure-sensitive resistor 9 through the pressure ring 8. The pressure-sensitive resistor 9 is electrically connected to the controller 12. When the pressure signal detected by the pressure-sensitive resistor 9 exceeds the set range value, the motor will be reversed through the controller 12, so that the pressing plate 10 indirectly drives the pressing plate 5 to rise, and thus no longer squeezes the materials, avoiding damage to the storage barrel 2 caused by excessive squeezing force of the pressing plate 5 on the materials, and further avoiding the occurrence of full-bin overflow.
