Description

Technical Field

[0001] This utility model relates to the field of brake protection technology, specifically to an intelligent paving head brake protection device. Background Technology

[0002] Straw plays an important role in agriculture, animal husbandry, and industry. In agricultural planting, straw is crushed into short pieces of a certain length and spread evenly on farmland through an intelligent paving head, which can increase the organic matter content of the soil and inhibit the growth of weeds. The intelligent paving head brake protection device is an automated safety device for conveyor belt paving heads, designed to ensure the safety and stability of the paving head during operation.

[0003] However, existing intelligent paving head brake protection devices lack the function of pre-cleaning the parts to be braked. Since the working environment of the paving head for straw is dusty and muddy, especially in rainy weather, the surface of the parts to be braked may be covered with dust and mud. When the brake device comes into contact with the parts to be braked, slippage may occur, affecting the braking effect.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0023] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0024] like Figures 1 to 4 As shown, an embodiment of this utility model provides an intelligent paving head brake protection device, including: an active roller 1; a braking part, which is movably connected to the active roller 1 to pre-clean the surface of the active roller 1 and stop the active roller 1 from rotating, thus completing the braking; and an installation part, which is fixedly connected to the braking part.

[0025] In this embodiment of the utility model, during use, due to the complex working environment of the straw laying head, the active roller 1 is easily contaminated with mud and dirt when encountering muddy environments, which affects the braking effect. The braking part is used to pre-clean the surface of the active roller 1 and stop the active roller 1 from rotating, so as to avoid slippage when the braking device contacts the active roller 1, which would affect the braking effect. After pre-cleaning, the delicate parts of the cleaning plate are easily covered with mud and dirt, which affects the cleaning effect during the next braking. Therefore, the mounting plate 22 can be quickly disassembled and installed, making it convenient to replace or clean the cleaning plate and avoid affecting the braking effect of the next time.

[0026] like Figures 1 to 4 As shown, it also includes: a soot blowing unit, which is movably connected to the braking unit; a paving body unit, which is fixedly connected to the active roller 1 and movably connected to the braking unit; and a monitoring and control unit, which is fixedly connected to the paving body unit.

[0027] In this embodiment of the utility model, the dust blowing part is set up so that the braking part is driven to blow dust when it is working, which speeds up the dust dispersion and prevents dust from adhering to the active roller 1 and affecting the braking effect; the paving body part is set up so that the material is transported to the appropriate position by the conveyor belt and laid; the monitoring and control part is set up so that the material condition is monitored in real time. When an accident occurs, the monitoring and control part transmits information to the motor 29 in a timely manner to start the braking device. At the same time, the information is transmitted to the motor 29 that drives the active roller 1 to rotate so that it stops. The prior art will not be explained in detail.

[0028] Information is transmitted between the various components of the monitoring and control department via digital electrical signals.

[0029] like Figures 1 to 4 As shown, the braking part includes: a brake block 21, which is movably connected to the active roller 1 and has an internal mounting part; a mounting plate 22, which is movably connected to the brake block 21; a spring 23, which is fixedly connected to the mounting plate 22; a cleaning plate 24, which is fixedly connected to the spring 23; a scraper 25, which is fixedly connected to the cleaning plate 24 and abuts against the active roller 1; a brush 26, which is fixedly connected to the cleaning plate 24 and abuts against the active roller 1; a sponge strip 27, which is fixedly connected to the cleaning plate 24 and abuts against the active roller 1; a bidirectional lead screw 28, which is slidably connected to the bottom of the brake block 21 and has a dust blowing part sleeved on its outer surface; and a motor 29, which is fixedly connected to the end of the bidirectional lead screw 28 and whose bottom abuts against the paving body.

[0030] In this embodiment of the utility model, during use, the starter motor 29 drives the bidirectional lead screw 28 to rotate, causing the two brake blocks 21 to move closer together. The cleaning plate 24 moves closer to the active roller 1, and the scraper 25 on it scrapes the dirt on the surface of the active roller 1. The brush 26 cleans the dust, and the sponge strip 27 cleans the water stains. During the cleaning process, the brake blocks 21 are still close to each other, and the spring 23 is compressed until the brake blocks 21 contact the active roller 1. The friction between the two increases by gradually increasing pressure, causing the active roller 1 to stop rotating and completing the braking.

[0031] Among them, the brake block 21 is provided with several silicone strips on the side that contacts the active roller 1, which can increase the friction between the brake block 21 and the active roller 1, improve the braking effect, and shorten the braking time.

[0032] In addition, a slider is provided at the bottom of the brake block 21, and a groove is provided on the support plate supporting the brake device. The slider slides in the groove, which guides the brake blocks 21 to move closer and further apart. This is shown in the figure but not marked.

[0033] like Figures 1 to 4As shown, the mounting part includes: a pull cylinder 31, which abuts against the brake block 21; a second spring 32, which is fixedly connected to the inner wall of the pull cylinder 31; a locking block 33, which is fixedly connected to the end of the second spring 32; a locking groove 34, which is formed on the mounting plate 22; a limiting groove 35, which is formed on the inner wall of the brake block 21; and a limiting strip 36, which is fixedly connected to the mounting plate 22.

[0034] In this embodiment of the utility model, pulling the pull tube 31 causes the locking block 33 to disengage from the locking groove 34. At this time, the mounting plate 22 can be removed from the brake block 21 and cleaned or replaced. Then, the mounting strip on the mounting plate 22 is aligned with the mounting groove in the brake block 21 and pressed to complete the quick installation of the mounting plate 22.

[0035] The cleaning plate after pre-cleaning is prone to mud and dirt adhering to its delicate parts, which can affect the cleaning effect during the next braking. Therefore, the mounting plate 22 can be quickly disassembled and installed to facilitate the replacement or cleaning of the cleaning plate and avoid affecting the next braking effect.

[0036] In addition, the locking block 33 here is triangular, with the least acute angle facing the head of the mounting plate 22 during installation. Therefore, when installing the mounting plate 22, it is only necessary to push the mounting plate 22. To remove the mounting plate 22, pull the pull tube 31 to drive the spring 32 to extend, causing the locking block 33 to disengage from the slot 34. The operation is simple and quick. In addition, the engagement of the limiting strip 36 and the limiting groove 35 has a guiding effect on the installation of the mounting plate 22.

[0037] like Figures 1 to 4 As shown, the soot blowing unit includes: a folded air cylinder 41, which is movably connected to a two-way lead screw 28; a top rod 42, one end of which is movably connected to a brake block 21, and the other end of which is fixedly connected to the folded air cylinder 41; and an air outlet cylinder 43, which is fixedly connected to the folded air cylinder 41.

[0038] In this embodiment of the utility model, as the two brake blocks 21 approach each other, their bottoms press against the top rod 42, compressing and folding the air cylinder 41. The gas inside the air cylinder is blown out from the air outlet 43, quickly dispersing the dust treated by the cleaning plate during pre-cleaning, thus assisting in cleaning.

[0039] When the folding air cylinder 41 is compressed, it can blow away dust and make it disperse quickly. When the braking ends and the two brake blocks 21 move away from each other, the folding air cylinder 41 slowly recovers and can still play a role in the next braking.

[0040] In addition, the gas blown out by the folding system has a cooling effect on the contact surface between the brake pads and the active roller, which can to some extent avoid accidents caused by excessive braking temperature. The exposed setting of the brake device is also for the purpose of heat dissipation efficiency.

[0041] like Figures 1 to 4 As shown, the paving body includes: a paving machine body 51, which is fixedly connected to the drive roller 1; and a caster wheel 52, which is rotatably connected to the paving machine body 51.

[0042] In this embodiment of the utility model, when in use, the material is transported to a suitable position by a conveyor belt and laid out, and the casters 52 facilitate the overall movement of the device and flexible laying.

[0043] like Figures 1 to 4 As shown, the monitoring and control unit includes: a speed sensor 61, which is fixedly connected to the active roller 1; an ultrasonic sensor 62, which is fixedly connected to the paving machine body 51; and a controller 63, which is fixedly connected to the speed sensor 61.

[0044] In this embodiment of the utility model, the speed sensor 61 here has the function of a photoelectric encoder and is installed on the active roller 1. The rotation of the active roller 1 determines the component transportation and laying speed, judges the running status of the laying head, and triggers the braking device when there is a problem. The ultrasonic sensor 62 is set at the feeding part of the conveyor belt. It uses the ultrasonic reflection characteristics to monitor the material height, accumulation, or whether there is a blockage. When there is a problem, it triggers the braking device in time. The controller 63 here is a PLC controller, which receives the electrical signals from the sensors and issues corresponding control commands to realize the emergency shutdown of the motor 29.

[0045] The above are all existing technologies and will not be explained in detail.

[0046] like Figures 1 to 4 As shown, the cross-section of the brake block 21 is arc-shaped, and the degree of curvature of the arc is the same as that of the active roller 1.

[0047] In this embodiment of the invention, the brake block 21 contacts the active roller 1 and gradually presses the active roller 1, causing it to stop rotating and completing the braking. The shape of the brake block 21 maximizes the contact surface between the brake block 21 and the active roller 1, which is beneficial to the braking effect.

[0048] Working principle: When in use, the starter motor 29 drives the bidirectional lead screw 28 to rotate, causing the two brake blocks 21 to move closer together. The cleaning plate 24 moves closer to the active roller 1, where the scraper 25 scrapes the dirt on the surface of the active roller 1, the brush 26 cleans the dust, and the sponge strip 27 cleans the water stains. During the cleaning process, the brake blocks 21 continue to move closer together, and the spring 23 is compressed until the brake blocks 21 contact the active roller 1. The friction between the two increases with the gradually increasing pressure, causing the active roller 1 to stop rotating and complete the braking. Pull the pull cylinder 31 to disengage the locking block 33 from the locking groove 34. At this time, the mounting plate 22 can be removed from the brake blocks 21 for cleaning or replacement. Then, align the mounting strip on the mounting plate 22 with the mounting groove in the brake block 21 and press it to complete the quick installation of the mounting plate 22. As the two brake blocks 21 move closer together, their bottoms press against the top rod 42, compressing and folding the air cylinder 41. The air in the air cylinder is blown out from the air outlet 43, quickly dispersing the dust treated by the cleaning plate during pre-cleaning and assisting in the cleaning process.

[0049] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
