Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to a paddy field deep fertilization furrow opener anti-sticking device. BACKGROUND

[0002] The anti-winding and anti-sticking device makes the furrow opener of the side deep fertilization mechanical part anti-clogging and anti-winding, which can be widely applied to the important link of paddy field mechanical side deep fertilization in crop planting. The side deep fertilization is a comprehensive paddy cultivation technology system integrating single technologies such as soil fertility improvement, strong seedling cultivation, irrigation management, pest control, fertilizer process and agricultural machinery selection. The anti-winding and anti-sticking device can ensure the operation quality, improve the production rate, reduce the production cost, increase the farmers' income, and promote the application of paddy field fertilization machinery.

[0003] At present, paddy field ditching is an important link in farmland water conservancy construction. The traditional paddy field furrow opener is prone to winding and sticking during use, which leads to low work efficiency and increases the labor intensity of farmers. Therefore, it is of great significance to develop a paddy field furrow opener with an anti-winding and anti-sticking device. The existing anti-winding device of the stirrer type separates the wheat straw by rotating the stirrer, and the method of scraping by high-pressure water flow rapidly flushes the soil, which consumes too much energy and may cause waste of water resources. The water flow pressure is not easy to control, which may cause damage to the working surface, and the problem of soil and residual stem complex adhering to the furrow opener cannot be solved.

[0075] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0076] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0077] The following reference Figures 1 to 8 This application describes an anti-sticking device for a deep fertilization ditch opener in paddy fields, provided according to some embodiments.

[0078] Example 1

[0079] A deep fertilization furrow opener anti-sticking device for paddy fields includes a soil-covered base plate 1, furrow openers 2, fertilization pipes 3, anti-tangling and anti-sticking mechanisms 4, float mechanisms 5, and a moving mechanism 6. Side mudguards 11 are fixedly connected to both sides of the soil-covered base plate 1. Multiple furrow openers 2 are disposed at one bottom end of the soil-covered base plate 1. The fertilization pipes 3 are inserted through the soil-covered base plate 1. Multiple anti-tangling and anti-sticking mechanisms 4 are disposed above the furrow openers 2 and connected to the soil-covered base plate 1. The float mechanism 5 is disposed at one end of the soil-covered base plate 1 near the furrow openers 2 and connected to the soil-covered base plate 1. The moving mechanism 6 is disposed at the bottom of the soil-covered base plate 1 and connected to the soil-covered base plate 1.

[0080] It should be noted that the soil-covering base plate 1, as the supporting structure of this device, has sufficient materials and hardness to meet the device's usage requirements. Side mudguards 11 are fixedly connected to both sides of the soil-covering base plate 1. These side mudguards 11 prevent soil and gravel from entering the device and causing malfunctions. Multiple trenchers 2 are installed at the bottom of the soil-covering base plate 1, enabling efficient trenching. A fertilizer pipe 3 runs through the soil-covering base plate 1. Workers can connect waste material to the end of the fertilizer pipe 3 located above the soil-covering base plate 1, allowing it to fall into the soil at the bottom of the soil-covering base plate 1. Through the combined use of the trenchers 2 and the fertilizer pipe 3, fertilizer can be applied to the trench after trenching. Furthermore, the fertilizer pipe 3 also... Multiple anti-tangling and anti-sticking mechanisms 4 can be set to increase fertilization efficiency; multiple anti-tangling and anti-sticking mechanisms 4 are set above the furrow opener 2, and the anti-tangling and anti-sticking mechanisms 4 are connected to the soil covering base plate 1. The anti-tangling and anti-sticking mechanisms 4 move up and down in the furrow opener 2 to remove the soil and stem residue complex attached to the furrow opener 2; setting multiple anti-tangling and anti-sticking mechanisms 4 at the same time can realize the soil removal of multiple furrow openers 2 at the same time, so as to increase the efficiency of the anti-tangling and anti-sticking mechanisms 4 in removing soil from the furrow opener; a float box mechanism 5 is set at the end of the soil covering base plate 1 near the furrow opener 2, that is, the front end of the device during the movement process. During the movement of the device, the float box mechanism 5 can push the soil in front of the device to flatten it, thereby reducing the resistance during the movement of the device; by setting a moving mechanism 6 at the bottom of the soil covering base plate, the device can be moved more conveniently.

[0081] Furthermore, the anti-entanglement and anti-sticking mechanism 4 includes a mounting plate 41, a controller, a ball screw lifting assembly 42, a scraper assembly 43, and a sensor 44; wherein, the mounting plate 41 is fixedly mounted on one end of the soil-covering base plate 1; the controller is mounted on the mounting plate 41; the ball screw lifting assembly 42 is mounted on the mounting plate 41 and is electrically connected to the controller; the scraper assembly 43 is connected to the ball screw lifting assembly 42, and one end of the scraper assembly 43 is in elastic contact with the end of the trencher 2 near the soil-covering base plate 1; the sensor 44 is mounted on the side mudguard 11 and is electrically connected to the controller.

[0082] It should be noted that the mounting plate 41 is used to install the various components of the anti-tangling and anti-adhesion mechanism 4, and also to fix the anti-tangling and anti-adhesion mechanism 4 to the soil cover plate 1. The controller, as the brain of the anti-tangling and anti-adhesion mechanism, rationally allocates the work of each component in the anti-tangling and anti-adhesion mechanism 4, so that the anti-tangling and anti-adhesion mechanism 4 can operate automatically and stably. By setting the ball screw lifting assembly 42, the ball screw lifting assembly 42 realizes the lifting and lowering movement according to its internal structure. The scraper assembly 43 is set on the ball screw lifting assembly 42 and connected to the ball screw lifting assembly 42. Thus, when the ball screw lifting assembly 42 lifts and lowers, it drives the scraper assembly 43 to lift and lower. One end of the scraper assembly 43 is in elastic contact with the trencher 2, so that the scraper assembly 4 can scrape up and down on the trencher 2, thereby scraping off the soil and stem residue complex on the trencher 2. The setting of the sensor 44 makes the anti-tangling and anti-adhesion mechanism 4 more intelligent and automated. On the side mudguard 11, sensor 44 is electrically connected to the controller. Sensor 44 faces the trencher 2. By measuring the distance between sensor 44 and trencher 2, it determines whether the soil on trencher 2 needs to be removed. When sensor 44 detects that the distance between side sensor 44 and trencher 2 is less than a preset distance threshold, it means that the soil thickness on trencher 2 has reached the required thickness for cleaning. At this time, sensor 44 sends a signal to the controller, and the controller sends a command to ball screw lifting assembly 42, causing ball screw lifting assembly 42 to drive scraper assembly 43 to perform lifting and reciprocating motion, so that scraper assembly 43 scrapes soil back and forth on trencher 2. When sensor 44 detects that the distance between side sensor 44 and trencher 2 is greater than or equal to the preset distance threshold, it sends a signal to the controller, and the controller will issue a stop motion command. Ball screw lifting assembly 42 resets, thereby driving scraper assembly 43 to reset, so that scraper assembly 43 returns to the end of trencher 2 near the soil cover plate 1.

[0083] Further, the ball screw lifting assembly 42 includes a first bearing housing 421, a screw 422, a second bearing housing 423, a motor 428, a screw nut 424, a slide rail 425, a connecting plate 426, and a tripod 427; wherein, the first bearing housing 421 is fixedly connected to the mounting plate 41; the second bearing housing 423 is fixedly connected to the mounting plate 41, and the second bearing housing 423 is vertically aligned with the first bearing housing 421; the screw 422 is disposed on the first bearing housing 421 and between the second bearing housing 423, and both ends of the screw 422 are rotatably connected to the first bearing housing 421 and the second bearing housing 423 respectively; the motor 428 is disposed at the end of the second bearing housing 423 away from the screw 422, and the motor 428... The motor 428 is fixedly mounted on the mounting plate 41 and connected to the lead screw 422 located in the second bearing seat 423 via a coupling. The motor 428 is electrically connected to the controller. The lead screw nut 424 is rotatably sleeved on the lead screw 422. Two slide rails 425 are respectively set on both sides of the lead screw 422 and are fixedly connected to the mounting plate 41. The connecting plate 426 is fixedly connected to the lead screw nut 424 and is slidably connected to the slide rail 425 on the side of the connecting plate 426 near the lead screw nut 424. The tripod 427 includes a main frame 4271 and two supports 4272 set on both sides of the main frame. The main frame 4271 is connected to the connecting plate 426, and a scraper assembly 43 is connected to the end of each of the two supports 4272 away from the main frame 4271.

[0084] It should be noted that when the controller receives a signal from sensor 44 indicating the need to clear mud, the controller sends a command to motor 428, which begins to rotate forward. The output shaft of motor 428 drives lead screw 422 to rotate forward via a coupling. Lead screw 422 is positioned between the first bearing seat 421 and the second bearing seat 423, with both ends of lead screw 422 rotatably connected to the first bearing seat 421 and the second bearing seat 423 respectively, making lead screw 422 more stable. The lead screw screw sleeve on lead screw 422... The nut 424 is connected to the connecting plate 426 and cannot rotate, thus causing the lead screw nut 424 to be subjected to axial force and begin to drive the connecting plate 426 to move downward along the axial direction of the lead screw 422. Two slide rails 425 are respectively set on both sides of the lead screw 422, and the slide rails 425 are fixedly connected to the mounting plate 41. The slide rail 425 on the side of the connecting plate 426 closest to the lead screw nut 424 is slidably connected, making the movement of the connecting plate 426 smoother. Through the cooperation of the slide rails 425, the lead screw 422, and the lead screw nut 424... This makes the descent of the connecting plate 426 more stable and smooth. When the connecting plate 426 moves downward, the tripod 427 located on the side of the connecting plate 426 away from the lead screw nut 424 also moves downward with the connecting plate 426. The tripod 427 includes a main frame 4271 and two supports 4272 set on both sides of the main frame. The main frame 4271 is connected to the connecting plate 426, and the ends of the two supports 4272 away from the main frame 4271 are connected to scraper assemblies 43. Therefore, ultimately, the two supports 4272 drive the two The scraper assembly 43 moves downward; when the scraper assembly 43 moves to the bottom of the trencher, the motor 428 starts to reverse. On the same principle, the two supports 4272 drive the two scraper assemblies 43 to move upward, and so on repeatedly; until the sensor 44 detects that the distance between the side sensor 44 and the trencher 2 is greater than or equal to the preset distance threshold, the controller controls the lead screw nut 424 to reset, thereby driving the connecting plate 426, the tripod 427 and the two scraper assemblies 43 connected to the tripod 427 to reset.

[0085] Furthermore, the scraper assembly 43 includes a connecting block 431, two scrapers 432 with the same structure, a positioning block 433, and a spring 434; wherein, the connecting block 431 is connected to the bracket 4272; both ends of the connecting block 431 away from the bracket 4272 are provided with rotating holes 4311; a rotating shaft 4321 is provided on one side of the scraper 432, and the two scrapers 432 are respectively disposed in the two rotating holes 4311 of the connecting block 431 through the rotating shaft 4321, with one end of the scraper 432 in elastic contact with the trencher 2; two positioning blocks 433 are respectively disposed at the ends of the two scrapers 432 away from the trencher 2; the spring 434 is disposed between the two positioning blocks 433, and both ends of the spring 434 are respectively connected to the two positioning blocks 433.

[0086] It should be noted that the connecting block 431, as a component in the scraper assembly 43 connected to the ball screw lifting assembly 42, moves up and down through the ball screw lifting assembly 42, causing the connecting block 431 to move up and down. Both ends of the connecting block 431 away from the bracket 4272 are provided with rotating holes 4311. A rotating shaft 4321 is provided on one side of the scraper 432, and the two scrapers 432 are respectively positioned in the two rotating holes 4311 of the connecting block 431 via the rotating shaft 4321. This allows the scraper 432 in the scraper assembly 43 to move up and down, scraping away the soil and stem residue on the furrow opener 2. Simultaneously, since the two scrapers 432 are rotatably connected to the rotating holes 4311 on both sides of the connecting block 431 via the rotating shaft 4321, the scrapers 432 are allowed to rotate at a certain angle around the axial direction of the rotating shaft 4321, thereby controlling the opening and closing degree between the two scrapers to better adapt to the uneven thickness of the furrow opener 2. Meanwhile, two positioning blocks 433 are respectively positioned in two... The scraper 432 is located away from one end of the trench opener 2. The spring 434 is positioned between two positioning blocks 433, with both ends of the spring 434 connected to the two positioning blocks 433 respectively. Through the spring 434, as the thickness of the trench opener 2 gradually widens during the movement of the two scrapers 432, the distance between the two scrapers 432 and the end of the trench opener 2 (located below the rotating shaft 4321) increases, thus reducing the distance between the two scrapers at the end above the rotating shaft 4321, thereby compressing the spring 434. When the thickness of the trench opener 2 gradually narrows again, the spring 434 releases pressure, restoring the distance between the two scrapers 432. By configuring the rotating shaft 4321, rotating hole 4311, and spring 434, the distance between the two scrapers 432 can be adjusted according to the change in the thickness of the trench opener 2 during movement, ensuring that the scrapers 432 remain close to the trench opener during movement. This increases the compatibility and applicability of the device and improves the efficiency of soil removal.

[0087] Furthermore, the slide rail 425 includes a triangular fixing bracket 4251 and a slide rail body 4252; wherein, the triangular fixing bracket 4251 is disposed on the mounting plate 41; and the slide rail body 4252 is disposed on one side of the triangular fixing bracket 4251.

[0088] It should be noted that by setting the slide rail body 4252 in the triangular fixing frame 4251, the stability of the slide rail body 4252 can be increased, thereby increasing the stability of the connecting plate 426 driving the scraper assembly 43 to remove the soil and stem composite, making the cleaning ability of the anti-tangling and anti-sticking mechanism 4 more reliable.

[0089] Furthermore, the connecting plate 426 includes a plate body 4261, a lead screw connection 4262, and a slider 4263; wherein, one side of the plate body 4261 is connected to the tripod 427; the lead screw connection 4262 is located on the side of the plate body 4261 away from the tripod 427, and the lead screw connection 4262 is connected to the lead screw nut 424; the slider 4263 is located on the side of the plate body 4261 close to the lead screw connection 4262, and the slider 4263 is slidably connected to the slide rail body 4252.

[0090] It should be noted that the plate body 4261 serves as a connecting structure for the tripod 427 and the lead screw nut 424. The lead screw connection 4262 is located on the side of the plate body 4261 away from the tripod 427. The lead screw connection 4262 is connected to the lead screw nut 424. When the lead screw nut 424 moves up and down, it drives the plate body 4261 to move up and down, thereby driving the tripod 427 to move up and down, and further driving the scraper assembly 43 connected to the two supports 4272 in the tripod 427 to descend. In addition, the slider 4263 is located on the side of the plate body 4261 close to the lead screw connection 4262. The slider 4263 is slidably connected to the slide rail body 4252. With the introduction of the slider 4263, during the up and down movement of the plate body 4252, the slider 4263 on the plate body 4252 slides up and down synchronously on the slide rail body 4252, thereby making the up and down process of the plate body 4261 more stable, and further making the scraper 432 more stable when scraping the soil and stem residue complex on the trencher 2.

[0091] Furthermore, the sensor 44 includes a sensor body 441, a sensor interface 442, and a sensor transmitter 443; wherein, the sensor body 441 is disposed on the side mudguard 11 and is electrically connected to the controller; the sensor interface 442 is disposed at one end of the sensor body 441 and is electrically connected to the controller; the sensor transmitter 443 is disposed at the end of the sensor body 441 near the trencher 2.

[0092] It should be noted that sensor interface 442 is located at one end of sensor body 441 and is electrically connected to the controller, thus establishing an electrical connection between sensor 441 and the controller. Sensor transmitter 443 is located at the end of sensor body 441 near trencher 2. Infrared light is emitted from sensor transmitter 443 to trencher 2 with a transmission period of 20 seconds. This means that the sensor performs a distance measurement every 20 seconds, or sends a control signal to the controller every 20 seconds. Sensor body 441 calculates the actual distance between itself and trencher 2 based on the time difference between the infrared emission time and the arrival time at trencher 2. This actual distance is then compared with a preset distance threshold between sensor body 441 and trencher 2. A comparison is performed; if the actual distance is less than the preset distance threshold, the soil thickness on the trencher 2 has reached the required cleaning thickness. At this time, the sensor body 441 sends a signal to the controller through the sensor interface 442. The controller sends a command to the ball screw lifting assembly 42, causing the ball screw lifting assembly 42 to drive the scraper assembly 43 to perform lifting and reciprocating motion, so that the scraper assembly 43 scrapes the soil back and forth on the trencher 2. When the sensor 44 detects that the actual distance between the side sensor 44 and the trencher 2 is greater than or equal to the preset distance threshold, it sends a signal to the controller. The controller will issue a stop motion command, and the ball screw lifting assembly 42 will reset, thereby driving the scraper assembly 43 to reset, so that the scraper assembly 43 returns to the end of the trencher 2 close to the soil cover plate 1.

[0093] Furthermore, the pontoon mechanism 5 includes a support plate 51, a pontoon bracket 52, and a pontoon 53; wherein, the support plate 51 is disposed on the top of the soil-covered base plate 1; the pontoon bracket 52 is disposed on the support plate 51; the pontoon 53 is disposed at one end of the soil-covered base plate 1, and the pontoon 53 is connected to the pontoon bracket 52.

[0094] It should be noted that the pontoon 53 is located at the end of the soil-covered bottom plate near the trencher. During the movement of this device, the pontoon can flatten the soil in front of the device, thereby reducing the resistance during the movement of the device; while the pontoon bracket 52 and the support plate 51 both provide sufficient support for the pontoon 53.

[0095] Furthermore, the moving mechanism 6 includes a U-shaped tube 61 and a roller 62; wherein, one end of the U-shaped tube 61 is located at the top of the soil-covered base plate 1, and the other end is located at the bottom of the soil-covered base plate 1, and the end of the U-shaped tube 61 located at the top of the soil-covered base plate 1 is connected to the soil-covered base plate 1; the roller 62 is located at the bottom of the soil-covered base plate 1, and the roller 62 is connected to the U-shaped tube 61.

[0096] It should be noted that one end of the U-shaped pipe 61 is located at the top of the soil-covered base plate 1, and the other end is located at the bottom of the soil-covered base plate 1. The design of the U-shaped pipe can not only support the roller 62, but also deliver water to irrigate the soil located at the bottom of the soil-covered base plate 1 after the trencher 2 has opened the trench.

[0097] Furthermore, it also includes a protective cover, which covers the anti-tangling and anti-sticking mechanism 4 and is fixedly connected to the mounting plate 41.

[0098] It should be noted that by setting a protective cover over the anti-tangling and anti-sticking mechanism 4, and fixing the protective cover to the mounting plate 41, the anti-tangling and anti-sticking mechanism 4 can be protected, preventing mud and gravel from entering during use and causing malfunctions.

[0099] According to this embodiment, a deep fertilization furrow opener anti-sticking device for paddy fields is used in the following process: furrow opener 2 is used to open furrows in the land; fertilization pipe 3 is used to fertilize the land after furrowing; float box 53 can level the soil in front of the device; rollers 62 enable easy movement of the device; and an anti-tangling and anti-sticking mechanism scrapes away soil and stem residue from furrow opener 2. Specifically, the scraping of soil and stem residue from furrow opener 2 is achieved by sensor transmitter 443 sending infrared rays to furrow opener 2. Sensor body 441 calculates the actual distance between sensor body 441 and furrow opener 2 based on the time difference between the infrared emission time and the time it reaches furrow opener 2, and then compares the actual distance with the preset distance between sensor body 441 and furrow opener 2. A threshold is compared; if the actual distance is less than the preset distance threshold, the soil thickness on the trencher 2 has reached the required cleaning thickness. At this time, the sensor body 441 sends a signal to the controller through the sensor interface 442. The controller sends a command to the ball screw lifting assembly 42, which in turn sends a command to the motor 428. The motor 428 starts to rotate forward. The output shaft of the motor 428 drives the screw 422 to rotate forward through the coupling. The screw 422 is set on the first bearing seat 421 and between the second bearing seat 423. The two ends of the screw 422 are rotatably connected to the first bearing seat 421 and the second bearing seat 423 respectively, making the screw 422 more stable. The screw nut 424, which is rotatably sleeved on the screw 422, is connected to the connecting plate 426 and cannot rotate, thus making the screw... When the nut 424 is subjected to axial force, it begins to drive the connecting plate 426 to move downward along the axial direction of the lead screw 422. Two slide rails 425 are respectively located on both sides of the lead screw 422, and are fixedly connected to the mounting plate 41. The slide rail 425 on the side of the connecting plate 426 closest to the lead screw nut 424 is slidably connected, making the movement of the connecting plate 426 smoother. Through the cooperation of the slide rails 425, the lead screw 422, and the lead screw nut 424, the connecting plate 426 becomes more stable and smooth during descent. When the connecting plate 426 moves downward, the tripod 427 located on the side of the connecting plate 426 furthest from the lead screw nut 424 also moves downward with the connecting plate 426. The tripod 427 includes a main frame 4271 and two slide rails 425 located on the side of the main frame. The two side supports 4272 are connected to the main frame 4271 and the connecting plate 426. The ends of the two supports 4272 away from the main frame 4271 are connected to scraper assemblies 43. Therefore, the two supports 4272 eventually drive the two scraper assemblies 43 to move downward. When the scraper assemblies 43 move to the bottom of the trencher, the motor 428 starts to reverse. On the same principle, the two supports 4272 drive the two scraper assemblies 43 to move upward. This movement is repeated until the sensor 44 detects that the distance between the side sensor 44 and the trencher 2 is greater than or equal to the preset distance threshold. At this time, the controller controls the lead screw nut 424 to reset, thereby driving the connecting plate 426, the tripod 427 and the two scraper assemblies 43 connected to the tripod 427 to reset.

[0100] According to this embodiment, a deep fertilization furrow opener anti-sticking device has the following beneficial effects: An anti-tangling and anti-sticking mechanism is installed above the furrow opener. Through the up-and-down movement of this mechanism, the soil and stem residue complex adhering to the furrow opener can be scraped off and removed, thus preventing the soil and stem residue complex from sticking or tangling on the furrow opener. A float box mechanism is installed at the end of the soil-covering base plate near the furrow opener. During the movement of this device, the float box can flatten the soil in front of the device, thereby reducing the resistance during movement. Sensors can be used to determine whether the soil thickness on the furrow opener has reached the required thickness, allowing the anti-tangling and anti-sticking mechanism to automatically scrape off the soil, thus increasing the automation level of the device. A moving mechanism is installed at the bottom of the soil-covering base plate, making the movement of the device more convenient and efficient. By simultaneously installing multiple furrow openers and multiple anti-tangling and anti-sticking mechanisms, the working efficiency of the device can be increased. Furthermore, multiple anti-tangling and anti-sticking mechanisms can simultaneously remove the soil and stem residue complex from the furrow opener, enhancing the removal efficiency of the anti-tangling and anti-sticking mechanism.
