Description

Technical Field

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

[0002] The anti-entanglement and anti-sticking device prevents congestion and entanglement of the side deep fertilization machinery parts, and the furrow opener can be widely used in the side deep fertilization of paddy field machinery, an important link in crop planting. Side deep fertilization is a rice cultivation technology system that integrates individual technologies such as soil fertility improvement, seedling cultivation, irrigation management, pest and disease control, fertilizer technology and agricultural machinery selection. The anti-entanglement and anti-sticking device can ensure operation quality, improve productivity, reduce production costs, increase farmers' income, and promote the application of paddy field fertilization machinery.

[0003] At present, paddy field furrowing is an important link in farmland water conservancy construction. Traditional paddy field furrow openers are prone to entanglement and adhesion problems during use, resulting in low work efficiency and increased labor intensity of farmers. Therefore, it is of great significance to develop a paddy field furrow opener with anti-entanglement and anti-sticking devices.

[0077] Refer to the following Figures 1 to 8 An anti-sticking device for a deep fertilization furrow opener in a paddy field is described according to some embodiments of the present application.

[0078] Example 1

[0079] A paddy field deep fertilization furrow opener anti-sticking device includes a soil covering base plate 1, a furrow opener 2, a fertilizer pipe 3, an anti-entanglement and anti-sticking mechanism 4, a buoyancy mechanism 5 and a movable mechanism 6; wherein, side fenders 11 are fixedly connected to both sides of the soil covering base plate 1; multiple furrow openers 2 are arranged at one end of the bottom of the soil covering base plate 1; the fertilizer pipe 3 is arranged through the soil covering base plate 1; multiple anti-entanglement and anti-sticking mechanisms 4 are arranged above the furrow openers 2, and the anti-entanglement and anti-sticking mechanisms 4 are connected to the soil covering base plate 1; the buoyancy mechanism 5 is arranged at one end of the soil covering base plate 1 close to the furrow opener 2, and the buoyancy mechanism 5 is connected to the soil covering base plate 1; the movable mechanism 6 is arranged at the bottom of the soil covering base plate 1, and the movable mechanism 6 is connected to the soil covering base plate 1.

[0080] It should be noted that the covering base plate 1 serves as the supporting structure of the device, and its practical material and hardness can meet the use requirements of the device, and side fenders 11 are fixedly connected to both sides of the covering base plate 1. Through the setting of the side fenders 11, the soil and gravel on both sides can be blocked outside the device to prevent soil and gravel from entering the device and causing device failure; by arranging multiple trench openers 2 at the bottom of the covering base plate 1, the device can achieve high-efficiency trenching work; and the fertilizer pipe 3 is set through the covering base plate 1, and the staff can connect the waste at the end of the fertilizer pipe 3 located above the covering base plate 1, so that it falls into the soil at the bottom of the covering base plate 1 through the fertilizer pipe 3. Through the coordinated use of the trench opener 2 and the fertilizer pipe 3, fertilizer can be applied to the trench through the fertilizer pipe 3 after the trenching work is completed; in addition, the fertilizer pipe 3 is also Multiple anti-entanglement and anti-sticking mechanisms 4 can be set to increase the fertilization efficiency; multiple anti-entanglement and anti-sticking mechanisms 4 are set above the furrow opener 2, and the anti-entanglement and anti-sticking mechanisms 4 are connected to the covering base plate 1. The anti-entanglement and anti-sticking mechanisms 4 move up and down in the furrow opener 2, thereby clearing the soil and residual stem complex attached to the furrow opener 2; setting multiple anti-entanglement and anti-sticking mechanisms 4 at the same time can realize the simultaneous removal of soil from multiple furrow openers 2, so as to increase the efficiency of the anti-entanglement and anti-sticking mechanisms 4 in clearing the soil in the furrow openers; a floating box mechanism 5 is set at one end of the covering base plate 1 close to the furrow opener 2, that is, the front end of the device during movement. During the movement of the device, the floating box mechanism 5 can flatten the soil in front of the device, thereby reducing the resistance of the device during movement; by setting a moving mechanism 6 at the bottom of the covering base plate, the device can be made more convenient and fast during movement.

[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 arranged at one end of the covering base plate 1; the controller is arranged on the mounting plate 41; the ball screw lifting assembly 42 is arranged on the mounting plate 41, and the ball screw lifting assembly 42 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 one end of the furrow opener 2 close to the covering base plate 1; the sensor 44 is arranged on the side fender 11, and the sensor 44 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-entanglement and anti-sticking mechanism 4, and the anti-entanglement and anti-sticking mechanism 4 is also fixed to the soil covering base plate 1 through the mounting plate 41; the controller serves as the brain of the anti-entanglement and anti-sticking mechanism, and reasonably distributes the work of the various components of the anti-entanglement and anti-sticking mechanism 4, so that the anti-entanglement and anti-sticking mechanism 4 can operate automatically and stably, and by setting a ball screw lifting assembly 42, the ball screw lifting assembly 42 realizes lifting and lowering movement according to its internal structure; and the scraper assembly 43 is set on the ball screw lifting assembly 42 and is connected to the ball screw lifting assembly 42, so that when the ball screw lifting assembly 42 is lifted and lowered, it drives the scraper assembly 43 to lift and lower movement, and one end of the scraper assembly 43 is in elastic contact with the furrow opener 2, so that the scraper assembly 4 can scrape up and down on the furrow opener 2, thereby scraping off the soil and residual stem complex on the furrow opener 2; and the setting of the sensor 44 makes the anti-entanglement and anti-sticking mechanism 4 more intelligent and automated. By setting the sensor 44 at On the side fender 11, the sensor 44 is electrically connected to the controller. The sensor 44 faces the trench opener 2 and determines whether the soil on the trench opener 2 needs to be cleared by measuring the distance between the sensor 44 and the trench opener 2. When the sensor 44 detects that the distance between the side sensor 44 and the trench opener 2 is less than the preset distance threshold, it means that the thickness of the soil on the trench opener 2 has reached the thickness that needs to be cleaned. At this time, the sensor 44 sends a signal to the controller, and the controller sends an instruction to the ball screw lifting assembly 42, so that the ball screw lifting assembly 42 drives the scraper assembly 43 to perform a lifting and reciprocating motion, so that the scraper assembly 43 scrapes the soil back and forth on the trench opener 2. When the sensor 44 detects that the distance between the side sensor 44 and the trench opener 2 is greater than or equal to the preset distance threshold, it sends a signal to the controller, and the controller will send a stop movement instruction, 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 trench opener 2 close to the covering base 1.

[0083] Furthermore, the ball screw lifting assembly 42 includes a first bearing seat 421, a screw 422, a second bearing seat 423, a motor 428, a screw nut 424, a slide rail 425, a connecting plate 426 and a tripod 427; wherein the first bearing seat 421 is fixedly connected to the mounting plate 41; the second bearing seat 423 is fixedly connected to the mounting plate 41, and the second bearing seat 423 is aligned with the first bearing seat 421 in the vertical direction; the screw 422 is arranged on the first bearing seat 421 and between the second bearing seat 423, and the two ends of the screw 422 are rotatably connected on the first bearing seat 421 and the second bearing seat 423 respectively; the motor 428 is arranged at one end of the second bearing seat 423 away from the screw 422, and the motor 428 It is fixedly set on the mounting plate 41, and the motor 428 is connected to the screw 422 located in the second bearing seat 423 through a coupling, and the motor 428 is electrically connected to the controller; the screw nut 424 is rotatably sleeved on the screw 422; two slide rails 425 are respectively arranged on both sides of the screw 422, and the slide rails 425 are fixedly connected to the mounting plate 41; the connecting plate 426 is fixedly connected to the screw nut 424, and the connecting plate 426 is slidingly connected to the slide rail 425 on the side close to the screw nut 424; the tripod 427 includes a main frame 4271 and two brackets 4272 arranged on both sides of the main frame, the main frame 4271 is connected to the connecting plate 426, and the two brackets 4272 are connected to the scraper assembly 43 at one end away from the main frame 4271.

[0084] It should be noted that when the controller receives the signal from the sensor 44 that the soil needs to be cleaned, the controller sends a command to the motor 428, and the motor 428 starts to rotate forward. The output shaft of the motor 428 drives the screw 422 to rotate forward through the coupling, and 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 respectively rotatably connected on the first bearing seat 421 and the second bearing seat 423, making the screw 422 more stable; the screw screw sleeved on the screw 422 is rotated. The nut 424 is connected to the connecting plate 426 and cannot rotate, so that the axial force on the lead screw nut 424 starts to drive the connecting plate 426 to move downward along the axial direction of the lead screw 422, and the two slide rails 425 are respectively provided on both sides of the lead screw 422, and the slide rails 425 are fixedly connected to the mounting plate 41; the connecting plate 426 is slidably connected to the slide rail 425 on the side close to the lead screw nut 424, so that the connecting plate 426 moves more smoothly in the countryside, and through the cooperation of the slide rails 425, the lead screw 422 and the lead screw nut 424, The connecting plate 426 is made more stable and smooth during the descent. 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 brackets 4272 arranged on both sides of the main frame. The main frame 4271 is connected to the connecting plate 426. The ends of the two brackets 4272 away from the main frame 4271 are both connected to the scraper assembly 43. Therefore, the two brackets 4272 eventually drive the two The scraper assembly 43 moves downward; the scraper assembly 43 moves to the bottom of the furrow opener, at which time the motor 428 starts to reverse, and the same principle causes the two brackets 4272 to drive the two scraper assemblies 43 to move upward, and this movement is repeated; until the sensor 44 detects that the distance between the side sensor 44 and the furrow opener 2 is greater than or equal to the preset distance threshold, at which time the controller controls the 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 of 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 arranged in the two rotating holes 4311 of the connecting block 431 through the rotating shaft 4321, and one end of the scraper 432 is elastically in contact with the furrow opener 2; the two positioning blocks 433 are respectively arranged at the ends of the two scrapers 432 away from the furrow opener 2; the spring 434 is arranged between the two positioning blocks 433, and the two ends of the spring 434 are respectively connected to the two positioning blocks 433.

[0086] The two ends of the connecting block 431 are provided with a rotating hole 4311 on the side away from the bracket 4272; a rotating shaft 4321 is provided on one side of the scraper 432, and the two scrapers 432 are respectively provided in the two rotating holes 4311 of the connecting block 431 through the rotating shaft 4321; thereby, the scrapers 432 in the scraper assembly 43 move up and down to scrape the soil and residual stem complex on the furrow opener 2; at the same time, since the two scrapers 432 are rotatably connected to the rotating holes 4311 on both sides of the connecting block 431 through the rotating shaft 4321, the scrapers 432 are allowed to rotate around the axial direction of the rotating shaft 4321 by a certain angle, thereby controlling the opening and closing degree between the two scrapers to better adapt to the uneven thickness of the furrow opener 2; at the same time, the two positioning blocks 433 are respectively provided at the two The scraper 432 is away from one end of the furrow opener 2, and the spring 434 is arranged between the two positioning blocks 433. The two ends of the spring 434 are respectively connected to the two positioning blocks 433. Through the setting of the spring 434, when the thickness of the furrow opener 2 gradually becomes wider during the movement of the two scrapers 432, the distance between the two scrapers 432 close to one end of the furrow opener 2 (the end located below the rotating shaft 4321) becomes larger, thereby making the distance between the two scrapers located above the rotating shaft 4321 become smaller, thereby squeezing the spring 434. When the thickness of the furrow opener 2 gradually narrows again, the spring 434 releases the pressure and resets the distance between the two scrapers 432. By setting the rotating shaft 4321, the rotating hole 4311 and the spring 434, the distance between the two scrapers 432 can be adjusted according to the change of the thickness of the furrow opener 2 during the movement, so that the scraper 432 is close to the furrow opener during the movement, thereby increasing the compatibility and applicability of the device and improving the efficiency of clearing the soil.

[0087] Furthermore, the slide rail 425 includes a triangular fixing frame 4251 and a slide rail body 4252 ; wherein the triangular fixing frame 4251 is disposed on the mounting plate 41 ; and the slide rail body 4252 is disposed on one side of the triangular fixing frame 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 in driving the scraper assembly 43 to remove the soil and residual stem complex, making the cleaning ability of the anti-entanglement and anti-sticking mechanism 4 more reliable.

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

[0090] The screw connection 4262 is arranged on the side of the plate body 4261 away from the tripod 427, and the screw connection 4262 is connected to the screw nut 424. When the 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 then driving the scraper assembly 43 connected by the two brackets 4272 in the tripod 427 to descend; in addition, the slider 4263 is arranged on the side of the plate body 4261 close to the screw connection 4262, and the slider 4263 is slidably connected to the slide rail body 4252; through 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 residual stem complex on the furrow opener 2 up and down.
