Description

Technical Field

[0001] This utility model belongs to the field of seeder technology, and in particular relates to an anti-tangling and blocking roller device for a crop seeder. Background Technology

[0002] In the prior art, a search revealed a Chinese patent that discloses "Anti-clogging roller device for a crop seeder," with publication number "CN219459809U." This patent mainly comprises a frame, an anti-clogging mechanism, and a cutting blade. The frame is fixedly installed on the front side of the seeder; the anti-clogging mechanism is rotatably installed on the frame; the anti-clogging mechanism includes a blade shaft and several rotating blades, with the blade shaft rotatably installed on the frame in a horizontal direction, and the several rotating blades fixedly spaced along the length of the blade shaft; the cutting blade is fixedly installed on the frame, and the cutting edge of the cutting blade is tangent to the cutting edge of the rotating blades.

[0003] Existing seeding anti-clogging devices are prone to seed accumulation in the discharge pipe due to differences in seed flowability and accumulation status within the feed hopper. In addition, the narrow structure of the discharge pipe makes unblocking extremely difficult once a blockage occurs. This not only increases equipment maintenance costs but also leads to a significant decrease in seeding efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging roller device for a crop seeder. By setting up an agitator, it solves the problem that seeds tend to accumulate in the discharge pipe due to differences in flowability and accumulation state in the feed box. In addition, the discharge pipe has a narrow structure, and once a blockage occurs, the unblocking operation is extremely difficult. This not only increases the equipment maintenance cost, but also leads to a significant decrease in sowing efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an anti-clogging roller device for a crop seeder, comprising a mixing section, and further comprising: an agitator, which is installed on the mixing section and is used to agitate the seeds entering the feed pipe to prevent clogging of the feed pipe and thus affecting the feeding of the mixing section; and a cutting section, which is set on the mixing section and is used to cut off weeds or residual film wrapped around the plow and harrow to prevent weeds or residual film from wrapping around the plow and harrow and affecting the sowing efficiency; wherein, by activating the agitator, the seeds in the feed pipe are agitated, which promotes the smooth flow of the seeds. Subsequently, the plow and harrow turn over the soil, allowing the falling seeds to fall into the tilled soil. At the same time, when the plow and harrow turn over the soil, the cutting section on it cuts off the weeds or residual film wrapped around the plow and harrow, preventing weeds or residual film from wrapping around the plow and harrow and thus affecting the sowing efficiency.

[0007] Furthermore, the stirring section includes a stirring assembly installed at the bottom of the mixing section for stirring the seeds entering the feeding pipe to prevent blockage; and a driving assembly installed on the mixing section for stirring the seeds within the mixing section to accelerate feeding, and also for transmitting power to the cutting section. Simultaneous activation of the stirring assembly and the driving assembly disturbs the seeds within the mixing section, allowing them to pass smoothly through the feeding pipe. Furthermore, the driving assembly transmits power to the cutting section on the plow, enabling it to cut tangled weeds or residual film, thus avoiding impact on sowing efficiency.

[0008] Furthermore, the cutting section includes a fixing component mounted on the mixing section to provide support for the cutting component; and a cutting component mounted on the fixing component to cut weeds or residual film entangled on the plow and harrow, preventing weeds or residual film from getting tangled on the plow and harrow and affecting sowing efficiency; wherein, the fixing plate, screw and nut in the fixing component cooperate with each other to install the cutting component. After the cutting component is fixed, the equipment can start the soil turning and sowing operation. During the operation, the cutting roller on the cutting component can cut the weeds or residual film entangled on the plow and harrow, effectively ensuring that the sowing efficiency is not affected.

[0009] Furthermore, the agitation assembly includes several feeding pipes fixedly connected to the bottom of the mixing section. A motor is located on the right side of the mixing section. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The rotating shaft passes through the feeding pipes and is rotatably connected to them. Several agitating blades are fitted on the outer walls of the rotating shafts. Each agitating blade is adapted to one of the feeding pipes. Each feeding pipe is equipped with a solenoid valve. A conveying pipe is fixedly connected to the bottom of each feeding pipe. When the motor is started, it drives the agitating blades to rotate via the rotating shaft, agitating the seeds entering the feeding pipes and effectively preventing the seeds from clogging the feeding pipes. At the same time, the solenoid valves open and close according to a pre-set program, ensuring that the seeds can be evenly conveyed to the tilled land via the conveying pipes.

[0010] Furthermore, the drive assembly includes a motor sleeve fixedly connected to the right side of the mixing section, and a second motor is fitted on the inner wall of the motor sleeve, with a stirring element provided on the second motor; wherein, the motor sleeve enables the second motor to output stably.

[0011] Furthermore, the fixing assembly includes a support frame fixedly connected to the mixing section. The front of the support frame is provided with several fixing plates, and the back of each of the fixing plates is fixedly connected with several screws. The outer walls of each of the screws are slidably connected with several sliding plates, and the outer walls of each of the screws are threadedly connected with nuts. The front of each of the fixing plates is provided with a plow or rake, and the ends of each of the conveying pipes are fixedly connected to the plow or rake. The screws, sliding plates, and nuts on the fixing plates cooperate with each other to fix the cutting part on the fixing plates, thereby completing the subsequent tilling and sowing.

[0012] Furthermore, the cutting assembly includes a rotating rod rotatably connected to several plows and harrows, with several cutting rollers sleeved on the outer wall of the rotating rod, and a driving component provided on the rotating rod; wherein, through the multiple cutting rollers on the plows and harrows, weeds or residual film entangled on the plows and harrows can be cleaned, avoiding any impact on the plows and harrows' turning and sowing operations.

[0013] Furthermore, the stirring component includes a second rotating shaft fixedly connected to the motor coupling. The second rotating shaft passes through the mixing section and rotates with the mixing section. The outer wall of the second rotating shaft is fitted with stirring blades, which are adapted to the mixing section. The stirring component and the agitation assembly work together to disturb the seeds in the mixing section, ensuring that the seeds are fed evenly and avoiding blockage.

[0014] Furthermore, the driving component includes gears that are both sleeved on the outer walls of the rotating shaft and the rotating rod, and the outer walls of the two gears are wound with toothed belts; wherein, the stirring component cooperates with the driving component to provide power to the cutting part.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up an agitator, the motor drives the agitator blades in the feeding pipe to rotate through the shaft, which agitates the seeds after they enter the feeding pipe. This prevents the seeds from getting stuck in the narrow feeding pipe. At the same time, the solenoid valve on the feeding pipe precisely controls the discharge volume according to a preset program, ensuring that the seeds are evenly sown into the soil turned over by the plow and harrow through the conveying pipe. This avoids increased equipment maintenance costs and reduced sowing efficiency due to blockage of the discharge pipe.

[0017] 2. By setting up a cutting section, when in use, first place the seeds in the mixing section, start the traction device to drive the equipment forward, and the plow and harrow simultaneously break the soil and turn it over. During this process, motor one and motor two are started at the same time. Motor two drives the mixing blade and gear to rotate through shaft two. The mixing blade continuously stirs the seeds in the mixing section to prevent them from piling up and affecting the feeding. The gears are driven by the gear belt meshing with the gears on the rotating rod, driving the rotating rod and cutting roller to rotate synchronously, cutting off the debris wrapped around the plow and harrow in time, and ensuring smooth soil turning and sowing operations.

[0028] Please see Figure 1-5 As shown, this utility model is an anti-clogging roller device for a crop seeder, including a mixing section 1, and further including: an agitator 2, which is installed on the mixing section 1 and is used to agitate the seeds entering the feed pipe 211 to prevent clogging of the feed pipe 211, thereby affecting the feeding of the mixing section 1; and a cutting section 3, which is set on the mixing section 1 and is used to cut weeds or residual film wrapped around the plow 316 to prevent weeds or residual film from wrapping around the plow 316 and affecting the sowing efficiency; wherein, by activating the agitator 2, the seeds in the feed pipe 211 are agitated, so that the seeds flow out smoothly. Subsequently, the plow 316 turns over the soil, so that the falling seeds fall into the tilled soil. At the same time, when the plow 316 turns over the soil, the cutting section 3 on it cuts the weeds or residual film wrapped around the plow 316, so as to prevent weeds or residual film from wrapping around the plow 316 and affecting the sowing efficiency.

[0029] The stirring section 2 includes a stirring assembly 21, which is installed at the bottom of the mixing section 1 and is used to stir the seeds entering the feed pipe 211 to prevent blockage; and a drive assembly 22, which is installed on the mixing section 1 and is used to stir the seeds in the mixing section 1 to accelerate the feeding process, and can also transmit power to the cutting section 3. The simultaneous activation of the stirring assembly 21 and the drive assembly 22 disturbs the seeds in the mixing section 1, allowing them to pass smoothly through the feed pipe 211. Simultaneously, the drive assembly 22 transmits power to the cutting section 3 on the plow 316, causing it to cut tangled weeds or residual film, thus avoiding affecting the sowing efficiency. 21 includes several feed pipes 211 fixedly connected to the bottom of the mixing section 1. A motor 212 is provided on the right side of the mixing section 1. The output shaft of the motor 212 is fixedly connected to a rotating shaft 213 via a coupling.

The stirring blade 224 is adapted to the mixing section 1; wherein, the stirring component and the agitation assembly 21 work together to agitate the seeds in the mixing section 1, ensuring that the seeds are fed evenly and avoiding blockage. By setting the agitation section, the motor 212 drives the stirring blade 214 in the feeding pipe 211 to rotate through the rotating shaft 213, and performs secondary agitation on the seeds that have been agitated by the stirring blade 224 and enter the feeding pipe 211, preventing the seeds from being blocked in the narrow feeding pipe. At the same time, the solenoid valve 215 on the feeding pipe precisely controls the discharge volume according to the preset program, ensuring that the seeds are evenly sown into the soil turned over by the plow 316 through the conveying pipe 216, avoiding increased equipment maintenance costs and reduced sowing efficiency due to blockage of the discharge pipe.

[0030] The cutting section 3 includes a fixing component 31, which is mounted on the mixing section 1 to provide support for the cutting component 32; and a cutting component 32, which is mounted on the fixing component 31 to cut weeds or residual film wrapped around the plow 316, preventing them from getting tangled and affecting sowing efficiency. The fixing component 31 utilizes a fixing plate 312, a screw 313, and a nut 315 to secure the cutting component 32. Once the cutting component 32 is fixed, the equipment can begin tilling and sowing operations. During operation, the cutting roller 322 on the cutting component 32 can cut the weeds or residual film wrapped around the plow 316.

The driving component includes gears 323 that are sleeved on the rotating shaft 223 and the outer wall of the rotating rod 321. The outer walls of the two gears 323 are wound with toothed belts 324. The mixing component and the driving component are matched. The mixing unit provides power to the cutting section 3. When using the cutting section, the seeds are first placed in the mixing section 1, and the traction device is started to drive the equipment forward. The plow and harrow 316 simultaneously breaks the soil and turns it over. During this process, motor 1 212 and motor 222 are started at the same time. Motor 222 drives the stirring blade 224 and gear 323 to rotate through the rotating shaft 223. The stirring blade 224 continuously stirs the seeds in the mixing section 1 to prevent them from accumulating and affecting the feeding. The gear 323 drives the rotating shaft 321 and the cutting roller 322 to rotate synchronously through the meshing of the toothed belt 324 and the gear on the rotating rod 321, so as to cut the debris wrapped on the plow and harrow 316 in time and ensure smooth soil turning and sowing operations.

[0031] One specific application of this embodiment is: Solenoid valve 215: It is an electromagnetic control valve device used in seed sowing equipment. By energizing the electromagnetic coil, it generates magnetic force to drive the valve core to move, thereby precisely controlling the opening and closing of the seed feeding channel, realizing precise control of the seed sowing quantity and sowing spacing. It has the characteristics of fast response, high degree of automation, energy saving and environmental protection, and is one of the key components of modern precision sowing equipment. In some sowing scales, solenoid valves controlled by PLC are used to open and close, and the sowing needs of different seeds are met by controlling the opening and closing of different diameter discharge ports.

[0032] In use, the seeds are first placed in the mixing section 1, and the traction device is started to move the equipment forward. The plow 316 simultaneously breaks and tills the soil. During this process, motor 1 212 and motor 222 are started at the same time. Motor 222 drives the stirring blade 224 and gear 323 to rotate through the rotating shaft 223. The stirring blade 224 continuously stirs the seeds in the mixing section 1 to prevent them from accumulating and affecting the feeding. The gear 323 meshes with the gear on the rotating rod 321 through the toothed belt 324, driving the rotating rod 321 and the cutting roller 322 to rotate synchronously and cut the seeds wrapped around the plow 316 in time. The debris on the 16 ensures smooth soil turning and sowing operations. At the same time, the motor 212 drives the stirring blade 214 in the feeding pipe 211 to rotate through the rotating shaft 213, which performs secondary stirring on the seeds that have been disturbed by the stirring blade 224 before entering the feeding pipe 211, preventing the seeds from clogging in the narrow feeding pipe. Meanwhile, the solenoid valve 215 on the feeding pipe precisely controls the discharge volume according to the preset program, ensuring that the seeds are evenly sown into the soil turned over by the plow and harrow 316 through the conveying pipe 216, avoiding increased equipment maintenance costs and reduced sowing efficiency due to blockage of the discharge pipe.
