Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric drive technology for clamp-and-row seeding, specifically to an electric drive structure for clamp-and-row seeding in a no-till seeder. Background Technology
[0002] No-till seeders are a new type of equipment used for farmland cultivation. They are mainly used to sow seeds without damaging the soil structure. Their finger-clamp seeding structure and electric drive system design play an important role in improving sowing efficiency and accuracy.
[0003] In the existing technology, the transmission process is relatively complicated and the cost is too high, which is not conducive to cost savings for users. The transmission process is also relatively complex.
[0004] To overcome the above shortcomings, Chinese Patent No. CN109247109A discloses a shaft and wheel transmission device for an electrically driven seeder. This device includes a fixed-position drive motor, two annular flywheels, and a transversely arranged transmission rod. A double transmission chain is mounted on one side of the drive motor, with a pitch gear in the middle of the double transmission chain. A fixed gear is located on one side of the double transmission chain, and a bearing is mounted on one side of the fixed gear. Several transmission bolts are located at one end of the transmission rod, and a shaft is located at one end of the transmission screw. The device employs multi-point transmission, with the drive motor providing overall power to rotate the double transmission chain. The pitch gear ensures the double transmission chain maintains a fixed distance. The transmission rod drives the flywheels to rotate. Several grooves are located in the middle of the flywheels, significantly reducing their weight, saving costs, and making rotation easier. The flywheels at both ends are connected to a wheel assembly via connecting rods, driving the device's movement.
[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, traditional no-till seeders have complex power transmission in the finger-clamp seeding process, the transmitted kinetic energy is easily reduced during transmission, and the control precision is low, which is not conducive to user operation. The power transmission takes time and the seeding speed is slow. Utility Model Content
[0006] The purpose of this utility model is to provide an electric drive structure for finger-clamp seeding in a no-till planter, in order to solve the problems mentioned in the background art, such as the complex power transmission of traditional finger-clamp seeding machines, the easy reduction of kinetic energy during transmission, the low control precision during use, the inconvenience to users, and the slow seeding speed due to the time required for power transmission.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a finger-clamp seeding electric drive structure for a no-till seeder, including a motor bracket welded assembly and a drive motor fixedly installed on the right side of the motor bracket welded assembly, wherein the output end of the drive motor passes through the motor bracket welded assembly and a transmission sprocket is provided at the output end of the drive motor.
[0008] The right side of the transmission sprocket is equipped with a motor drive tooth bladder via a first cross-head bolt, and a spring washer and a large washer are provided between the first cross-head bolt and the motor drive tooth bladder.
[0009] The right end of the motor-driven tooth bladder is fixedly installed at the output end of the drive motor. The drive motor is installed on the motor bracket welded part by a second cross-head bolt, and a spring washer and a flat washer are provided between the second cross-head bolt and the motor bracket welded part.
[0010] The transmission sprocket has a first bearing fixedly installed inside its left side, and the sprocket shaft is fixedly installed inside the first bearing.
[0011] Furthermore, a retaining ring for a hole is provided on the left side of the first bearing, and a retaining ring for a shaft is provided on the right side of the first bearing.
[0012] Furthermore, a fixing plate is fixedly installed on the lower left side of the motor bracket welded part, and a stabilizing and shock-absorbing mechanism is provided on the upper end of the fixing plate. The stabilizing and shock-absorbing mechanism is provided with a second bearing, and the middle end of the second bearing is sleeved on the surface of the sprocket shaft.
[0013] Furthermore, the stabilizing and shock-absorbing mechanism also includes a protruding plate fixedly installed on the upper end of the fixed plate, and a positioning rod is fixedly installed on the inner side of the protruding plate. There are two positioning rods, and a movable block is installed through the surface of the positioning rod. An adjusting plate is rotatably installed on the upper end of the movable block, and the upper end of the adjusting plate is rotatably installed on the lower end of the support plate. The upper end of the support plate is fixedly installed on the lower end of the second bearing.
[0014] Furthermore, support rods are provided on the left and right sides of the second bearing, and the lower ends of the support rods are fixedly installed on the surface of the support plate.
[0015] Furthermore, a buffer spring is fixedly installed on the outer side of the movable block, and the outer side of the buffer spring is fixedly installed on the inner side of the convex plate.
[0016] Furthermore, a damping rod is installed through the middle of the fixed plate, and the upper end of the damping rod is fixedly installed at the bottom center of the support plate.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. An intelligent control system is used to precisely control the motor speed, thereby achieving precise control over the seeding speed and quantity of the finger clamps and improving sowing accuracy;
[0019] Furthermore, the electric drive structure is relatively simple, with lower operating costs, reducing the cost for users, making it easy for staff to use and learn, and reducing power transmission losses.
[0020] 2. When the device is used for driving, the sprocket shaft is prone to shaking, which can cause instability in the electric drive structure. When the sprocket shaft shakes, it transmits the vibration force to the second bearing. When the second bearing shakes, it applies force to the support plate. The support plate and the second bearing are connected by a support rod to improve the strength of the installation structure between the second bearing and the support plate.
[0021] Furthermore, when the support plate shakes, force is applied to the adjusting plate. When the adjusting plate shakes, it pushes the movable block through the rotational connection at both ends. With the damping rod in place, the reciprocating vibration of the buffer spring can be avoided, improving the stability of the device and preventing the sprocket shaft from shaking. This further ensures that the electric drive of the finger clamp seeding machine of the no-till seeder is more stable. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1: As Figures 1-3 The technical solution shown is a finger-clamp seeding electric drive structure for a no-till seeder. To solve the problems of complex transmission and low transmission accuracy, the following is disclosed: a motor bracket welded assembly 1 and a drive motor 4 fixedly installed on the right side of the motor bracket welded assembly 1, with the output end of the drive motor 4 passing through the motor bracket welded assembly 1. A transmission sprocket 2 is provided at the output end of the drive motor 4. A motor drive tooth 3 is installed on the right side of the transmission sprocket 2 through a first cross-head bolt 9, and a spring washer and a large washer are provided between the first cross-head bolt 9 and the motor drive tooth 3. The right end of the motor drive tooth 3 is fixedly installed at the output end of the drive motor 4. The drive motor 4 is installed on the motor bracket welded assembly 1 through a second cross-head bolt 10, and a spring washer and a flat washer are provided between the second cross-head bolt 10 and the motor bracket welded assembly 1. A first bearing 7 is fixedly installed inside the left side of the transmission sprocket 2, and a sprocket shaft 5 is fixedly installed inside the first bearing 7. A retaining ring 6 for a hole is provided on the left side of the first bearing 7, and a retaining ring 8 for a shaft is provided on the right side of the first bearing 7.
[0031] When using this electric drive structure, the entire device is fixedly installed in a suitable position by the motor bracket welded assembly 1. During use, the drive motor 4 drives the drive tooth 3 to drive the transmission sprocket 2. The transmission sprocket 2 can control the seeding drive of the seeder finger clips. The transmission sprocket 2 drives the sprocket shaft 5 through the first bearing 7. The device adopts an intelligent control system to precisely control the motor speed, thereby achieving precise control of the seeding speed and quantity of the finger clips, improving the seeding accuracy. This electric drive structure is relatively simple, with low operating costs, reducing the cost for users, facilitating operation, and reducing power transmission losses.
[0032] Example 2: Figures 1-6The technical solution shown, based on Embodiment 1, discloses the following to address the problem of unstable transmission caused by shaking during power transmission: a fixing plate 11 is fixedly installed on the lower left side of the motor bracket welded part 1, and a stabilizing and anti-vibration mechanism is provided on the upper end of the fixing plate 11. The stabilizing and anti-vibration mechanism includes a second bearing 18, with the middle end of the second bearing 18 sleeved on the surface of the sprocket shaft 5. The stabilizing and anti-vibration mechanism also includes a protruding plate 12 fixedly installed on the upper end of the fixing plate 11, and two positioning rods 13 are fixedly installed on the inner side of the protruding plate 12. The surfaces of the positioning rods 13... A movable block 14 is installed through the plate. An adjusting plate 15 is rotatably installed on the upper end of the movable block 14. The upper end of the adjusting plate 15 is rotatably installed on the lower end of the support plate 16. The upper end of the support plate 16 is fixedly installed on the lower end of the second bearing 18. Support rods are provided on the left and right sides of the second bearing 18. The lower ends of the support rods are fixedly installed on the surface of the support plate 16. A buffer spring 17 is fixedly installed on the outer side of the movable block 14. The outer side of the buffer spring 17 is fixedly installed on the inner side of the protrusion plate 12. A damping rod 19 is installed through the middle of the fixed plate 11. The upper end of the damping rod 19 is fixedly installed at the bottom center of the support plate 16.
[0033] When the device is in use, the sprocket shaft 5 is prone to shaking, which can cause instability in the electric drive structure. When the sprocket shaft 5 shakes, it transmits the vibration force to the second bearing 18. When the second bearing 18 shakes, it applies force to the support plate 16. The support plate 16 and the second bearing 18 are connected by a support rod to improve the installation structure strength between them. When the support plate 16 shakes, it applies force to the adjusting plate 15. When the adjusting plate 15 shakes, it pushes the movable block 14 through the rotational connection between its upper and lower ends. The movable block 14 is pushed to slide along the positioning rod 13 and compress the buffer spring 17. The buffer spring 17 is compressed under the support of the convex plate 12 at the upper end of the fixed plate 11 to buffer the force of the sprocket shaft 5 shaking. At the same time, with the damping rod 19, the buffer spring 17 can be prevented from vibrating back and forth, improving the stability of the device and preventing the sprocket shaft 5 from shaking. This further ensures that the electric drive of the finger-clamp seeding machine is more stable.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
