Description

Technical Field

[0001] This utility model relates to the field of seeder technology, specifically a multi-functional seeder. Background Technology

[0002] The first seeder was made in Greece in 1636, and the Russians made a plow-type seeder in 1830. After 1860, Britain and the United States mass-produced animal-powered grain row seeders. In the 20th century, traction and suspended grain row seeders and pneumatic seeders appeared. In 1958, Norway produced the first centrifugal seeder. After the 1950s, various precision seeders were developed. Centrifugal seeders consist of a seed box and a seeding wheel. Seeds fall from the seed box onto the seeding wheel and are spread tangentially under centrifugal force. The seeding wheel is rotated by the traveling wheel. Seeds are discharged from the seed box into the seed delivery tube according to the required sowing amount, fall into the prepared furrows through the furrow opener, and are then covered and compacted by the soil covering and compaction device. According to a certain row spacing and hole spacing, each seeder unit can complete the entire operation process of furrow opening, seeding, soil covering, and compaction. They are mostly used in single-unit form, and multiple units are mounted on the same crossbeam according to the required row spacing to form hole seeders with different numbers of rows and working widths.

[0003] Existing seeders change the seeding frequency by changing the seed metering disc or seed metering wheel during operation. However, this requires preparing a variety of seed metering discs or seed metering wheels of different specifications, which increases the difficulty of equipment maintenance and management. Moreover, the replacement process is relatively cumbersome, requires stopping the machine and possessing certain operating skills, which affects seeding efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-functional seeder to solve the problems mentioned in the background art, such as the need to prepare various seed metering trays or seed metering wheels of different specifications, which increases the difficulty of equipment maintenance and management, and the replacement process is relatively cumbersome, requires machine shutdown and certain operating skills, and affects the sowing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional seeder, including a mounting bracket with two transmission rollers mounted on its surface. A first pulley is fixedly connected to one end of each transmission roller. Two first support plates are fixedly connected to the surface of the mounting bracket. A second support plate is fixedly connected to the upper surface of each first support plate. A raw material storage box is fixedly connected to the upper surface of the second support plate. A second pulley is mounted on the surface of the mounting bracket, and a transmission gear is fixedly connected to one end of the shaft of the second pulley. Two positioning baffles are fixedly connected to the side surface of the transmission gear. A digging claw is fixedly connected between the two positioning baffles. A linkage feeding mechanism is installed between the first and second support plates. This mechanism, through the linkage gear, drives a pressing cam to push the support baffles, support slides, and material-blocking pressure plates to slide, facilitating the introduction of raw materials into the feeding pipe.

[0006] Preferably, the mounting bracket and the transmission roller are rotatably connected, the first pulley and the mounting bracket are rotatably connected, and a belt is provided between the outer surface of the first pulley and the outer surface of the second pulley.

[0007] Using the above technical solution, when the transmission roller rotates, it transmits power to the first pulley, which is fixedly connected to it, through a rotatable connection with the mounting bracket. The first pulley then uses a belt to efficiently transmit the power to the second pulley.

[0008] Preferably, the second support plate is L-shaped, the second pulley is rotatably connected to the first support plate, a cavity is provided between the two positioning baffles, the digging claws are arranged in a circumferential array, and an opening is provided on the surface of one of the positioning baffles.

[0009] By adopting the above technical solution, the L-shaped design provides a stable and reasonable support structure for the raw material storage box. Its horizontal part can firmly place the raw material storage box, ensuring that the raw material storage box will not shake or shift during the operation of the seeder, thus guaranteeing the stable storage of the raw materials.

[0010] Preferably, the linkage feeding mechanism includes an extrusion cam, which is installed on the inner surface of the first support plate. One end of the rotating shaft of the extrusion cam is fixedly connected to a linkage gear. A support slide is installed through the second support plate and the raw material storage box. A support baffle is fixedly connected to the lower end of the support slide. A material blocking plate is fixed to the upper end of the support baffle. A material guiding pipe is installed through the surface of the second support plate.

[0011] Using the above technical solution, when the transmission gear rotates, it drives the linkage gear to rotate, which in turn causes the extrusion cam to rotate. During the rotation process, the profile of the extrusion cam changes continuously, pushing the support baffle, support slide column and material stop plate to slide back and forth.

[0012] Preferably, the extrusion cam is rotatably connected to the first support plate, the linkage gear is meshed with the transmission gear, and the support slide is slidably connected to the first support plate and the second support plate respectively.

[0013] Using the above technical solution, the extrusion cam can rotate continuously and stably under the drive of the linkage gear. Its special contour shape drives the support baffle, support slide column and material stop plate to reciprocate. The meshing connection between the linkage gear and the transmission gear realizes the effective transmission of power and precise control of motion.

[0014] Preferably, a spring is connected between the support baffle and the second support plate, the side surface of the baffle plate is inclined, and the width of the baffle plate is greater than the width of the guide pipe.

[0015] Using the above technical solution, when the extrusion cam pushes the support baffle, support slide column and material stop plate downward, the spring will generate a reverse elastic force, causing the material stop plate to quickly reset and fit tightly against the top of the guide pipe.

[0016] Preferably, the upper end of the material guide pipe penetrates the surface of the second support plate and the raw material storage box, and the lower end of the material guide pipe penetrates the opening of the positioning baffle on one side.

[0017] Using the above technical solution, the upper end of the material guide pipe passes through the second support plate and the raw material storage box, which can directly introduce the raw material in the raw material storage box into the pipe.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This multi-functional seeder:

[0019] 1. The transmission gear and linkage gear drive the extrusion cam, which pushes the support baffle, support slide column and material blocking plate to slide and control the amount and frequency of raw material entering the guide pipe. The digging claw rotates to dig the soil and accurately guides the raw material into the opening between the two positioning baffles through the guide pipe. At the same time, the width of the material blocking plate is larger than the guide pipe. Under the action of the spring, it can accurately control the amount of raw material falling, ensuring that the seeding amount is consistent each time and improving the seeding accuracy.

[0020] 2. The mounting bracket is rotatably connected to the transmission roller and the first pulley respectively. The first pulley and the second pulley are connected by belt drive to provide stable power transmission for the equipment. The L-shaped design of the second support plate stably supports the raw material storage box. All components are tightly connected. The support slide column is slidably connected to the first and second support plates to ensure stable movement of the baffle plate, reduce shaking and failure during equipment operation, and enhance stability and reliability. The belt drive not only realizes power transmission, but also facilitates installation and maintenance.

[0021] 3. By adjusting the transmission ratio, the rotation speed of the digging claw and the working frequency of the linkage feeding mechanism can be changed to adapt to different seed types and sowing spacing requirements. Under different sowing conditions, the sowing amount and frequency can be flexibly adjusted to expand the application range of the seeder and meet the diverse needs of agricultural production.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Please see Figure 1-6 This utility model provides a technical solution: a multi-functional seeder, including a mounting bracket 1, transmission rollers 2, a first pulley 3, a first support plate 4, a second support plate 5, a raw material storage box 6, a positioning baffle 7, a digging claw 8, a transmission gear 9, a second pulley 10, a linkage gear 11, a pressing cam 12, a support baffle 13, a support slide column 14, a material blocking pressure plate 15, and a material guiding pipe 16. The mounting bracket 1 has two transmission rollers 2 mounted on its surface. One end of the transmission roller 2 is fixedly connected to the first pulley 3. The mounting bracket 1 and the transmission rollers 2 are rotatably connected. The first pulley 3 and the mounting bracket 1 are rotatably connected. A belt is provided between the outer surface of the first pulley 3 and the outer surface of the second pulley 10. When the seeder is working, the transmission rollers 2 on the mounting bracket 1 start to rotate, causing the first pulley 3 to rotate as well. The belt provided between the outer surface of the first pulley 3 and the outer surface of the second pulley 10 plays a role in transmitting the power of the first pulley 3 to the second pulley 10.

[0031] Two first support plates 4 are fixedly connected to the surface of the mounting bracket 1. A second support plate 5 is fixedly connected to the upper surface of the first support plate 4. A raw material storage box 6 is fixedly connected to the upper surface of the second support plate 5. A second pulley 10 is mounted on the surface of the mounting bracket 1, and a transmission gear 9 is fixedly connected to one end of the shaft of the second pulley 10. The second support plate 5 is L-shaped. The second pulley 10 and the first support plate 4 are rotatably connected. A cavity is provided between the two positioning baffles 7. The digging claws 8 are arranged in a circumferential array. An opening is provided on the surface of one side of the positioning baffle 7. The second pulley 10 and the first support plate 4 are rotatably connected. After obtaining power, it drives the transmission gear 9 fixedly connected to one end of its shaft to rotate. When the transmission gear 9 rotates, the two positioning baffles 7 fixedly connected to its side surface drive the digging claws 8 to rotate synchronously. The digging claws 8 dig and loosen the soil. At the same time as the transmission gear 9 rotates, the linkage gear 11 meshing with it also rotates. The linkage gear 11 is fixed to one end of the shaft of the extrusion cam 12, so that the extrusion cam 12 rotates synchronously.

[0032] Two positioning baffles 7 are fixedly connected to the side surface of the transmission gear 9. A digging claw 8 is fixedly connected between the two positioning baffles 7. The linkage feeding mechanism includes a pressing cam 12. The pressing cam 12 is installed on the inner surface of the first support plate 4. A linkage gear 11 is fixedly connected to one end of the rotating shaft of the pressing cam 12. A support slide column 14 is installed through the second support plate 5 and the raw material storage box 6. A support baffle 13 is fixedly connected to the lower end of the support slide column 14. A material blocking plate 15 is fixed to the upper end of the support baffle 13. A material guiding pipe 16 is installed through the surface of the second support plate 5. During the rotation of the pressing cam 12, its special contour shape pushes the support baffle 13, the support slide column 14 and the material blocking plate 15 to slide vertically. When the pressing cam 12 pushes the material blocking plate 15 to move upward, the material blocking plate 15 moves away from the inlet of the material guiding pipe 16. The raw material falls from the material guiding pipe 16 and finally falls between the two positioning baffles 7 for sowing.

[0033] A linkage feeding mechanism is installed between the first support plate 4 and the second support plate 5. This mechanism, via a linkage gear 11, drives the extrusion cam 12 to slide the support baffle 13, support slide column 14, and material blocking plate 15, facilitating the introduction of raw materials into the feed pipe 16. The extrusion cam 12 is rotatably connected to the first support plate 4, the linkage gear 11 is meshed with the transmission gear 9, and the support slide column 14 is slidably connected to both the first and second support plates 4 and 5. A spring connects the support baffle 13 and the second support plate 5. The 5th side surface is designed with an inclination. The width of the baffle plate 15 is greater than the width of the guide pipe 16. The upper end of the guide pipe 16 passes through the surface of the second support plate 5 and the raw material storage box 6. The lower end of the guide pipe 16 passes through the opening of the positioning baffle 7 on one side. When the extrusion cam 12 stops pushing, the spring force causes the baffle plate 15 to reset and descend, so that the baffle plate 15 blocks the inlet of the guide pipe 16 and stops the material feeding. Thus, through the continuous rotation of the extrusion cam 12, the intermittent control of the material feeding is achieved, so as to achieve the purpose of precise seeding.

[0034] Working principle: When using this multi-functional seeder, the transmission roller 2 rotates first, which drives the second pulley 10 and the transmission gear 9 to rotate via the belt, realizing power transmission. The transmission gear 9 drives the positioning baffle 7 and the digging claw 8 to rotate and dig the soil. At the same time, the transmission gear 9 meshes with and drives the linkage gear 11 to rotate, which in turn drives the extrusion cam 12 to rotate. The extrusion cam 12 pushes the support baffle 13, the support slide column 14 and the material blocking plate 15 to slide upward, so that the spring and the material blocking plate 15 control the material to be discharged. This makes it easier for the material to fall from the guide pipe 16 between the two positioning baffles 7 for discharge, thereby completing the sowing operation and increasing the overall practicality.

[0035] 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.
