Description

Technical Field

[0001] This utility model relates to the field of vegetable planting technology, specifically to a vegetable sowing device with adjustable spacing. Background Technology

[0002] Vegetable sowing is a crucial link in agricultural production, and its efficiency and quality are directly related to vegetable yield and planting benefits. With the development of agricultural mechanization, traditional manual sowing methods have been gradually replaced by various sowing machines due to their low efficiency and high labor intensity. In existing technologies, vegetable sowing devices usually consist of a power mechanism, a sowing unit, a furrow opener, and a soil covering device, but they still have many shortcomings in terms of adaptability, precision, and stability. Currently, common seeding devices use scoops to sow single seeds or a fixed number of seeds. However, in actual use, the vibration generated by the machine's movement can easily cause the seeds in the scoop to fall out, resulting in uneven sowing amount and inconsistent density, which affects the quality of seedling emergence. In addition, different vegetable varieties have significantly different requirements for seed size and sowing spacing, but existing seeding devices mostly use fixed-size seed troughs or sowing trays, which are difficult to flexibly adapt to various crops. If the capacity of the sowing trough is not adjustable, it will lead to small seeds being sown too densely or large seeds being sown sparsely, which not only wastes seeds but may also reduce yield due to competition between seedlings or missing seedlings in the rows. In summary, current vegetable planting devices urgently need to address the issue of poor adjustability of planting spacing in order to adapt to diverse planting needs. Utility Model Content

[0003] The purpose of this invention is to provide a vegetable sowing device with adjustable spacing to solve the problem of poor sowing spacing adjustability mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vegetable sowing device with adjustable spacing, comprising a powered self-propelled frame, a mounting frame fixedly connected to the lower end of one side of the powered self-propelled frame, positioning holes evenly provided on the outer surface of the mounting frame, displacement wheels fixedly mounted on the outer surface of the mounting frame, and a sliding functional frame mounted on the outer surface of the mounting frame, a transmission rod fixedly connected to the power output end of the powered self-propelled frame, one end of the transmission rod penetrating the outer surface of the functional frame, and a connecting gear connected to the end of the transmission rod penetrating the functional frame, a seeder fixedly mounted to one end of the functional frame, and a transmission gear fixedly connected to the power input end of the seeder, and a transmission chain connecting the transmission gear and the connecting gear, the connecting gear being rotatably connected to the functional frame; A mounting plate is provided on one side of the mounting frame, and the mounting plate is fixedly installed to the mounting frame by locking bolts. Locking plates are engaged at the upper and lower ends of the mounting plate, and locking posts are fixedly provided on the outer surface of the two locking plates facing each other. A rotating center rod is installed in the center of the outer surface of the mounting plate, and a sliding plate is provided inside one end of the center rod. A rotating rod is installed at one end of the sliding plate. A limit block is fixedly provided on the outer surface of the mounting plate.

[0005] Preferably, the shaft section of the transmission rod is hexagonal, and the transmission rod and the connecting gear are slidably connected.

[0006] By adopting the above technical solution, the transmission rod 6 can maintain relative sliding with the connecting gear 7 when it slides and adjusts its position with the functional frame 5, and can also stably transmit torque through its hexagonal cross section, thus ensuring the continuity and reliability of power transmission.

[0007] Preferably, the locking plate is engaged with the positioning hole via a locking post, and the locking post is located on both sides of the locking bolt.

[0008] By adopting the above technical solution, the horizontal position of the functional frame 5 can be quickly and accurately fixed by engaging the locking post 14 with the positioning holes 3 at different positions, thereby realizing flexible adjustment and firm locking of the sowing row spacing. The structure is simple and reliable.

[0009] Preferably, the longitudinal section of the central rod is T-shaped, and the central rod and the sliding plate are slidably connected.

[0010] By adopting the above technical solution, the T-shaped design of the central rod 15 facilitates manual rotation operation, and its sliding connection with the sliding plate 16 provides a structural basis for the subsequent rotation-driven locking mechanism.

[0011] Preferably, the sliding plate and the rotating rod are concentrically arranged, and the rotating rod and the center rod are clearance-fitted, with a spring connecting the sliding plate and the center rod.

[0012] Using the above technical solution, the spring provides the restoring force of the sliding plate 16, ensuring that the rotating rod 17 and the limiting block 18 remain in contact to lock the position in the non-adjustment state. The clearance fit ensures the smooth rotation of the rotating rod 17, thereby realizing the synchronous opening and closing of the locking plates 13 on both sides by rotating the central rod 15.

[0013] Preferably, the rotating rod is T-shaped, and both ends of the rotating rod are respectively attached to the opposite ends of the two locking plates.

[0014] By adopting the above technical solution, both ends of the T-shaped rotating rod 17 can act on the upper and lower locking plates 13 simultaneously, ensuring that when the center rod 15 is rotated, the two locking plates 13 can be driven to move synchronously in opposite directions, realizing fast and synchronous locking and releasing functions, and making operation simple.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the adjustable spacing vegetable sowing device: 1. The device uses a sliding functional frame and a mounting frame with positioning holes to allow the position of the seeder relative to the self-propelled frame to be adjusted laterally. This design allows users to flexibly change the row spacing according to the agronomic requirements of different vegetable varieties, effectively solving the problems of fixed row spacing and poor adaptability of traditional seeders. The locking plate, locking post and positioning hole are connected by a simple and reliable structure, which can ensure that the functional frame is firmly locked during operation, ensuring the stability of the row spacing and the accuracy of the sowing. 2. A hexagonal transmission rod is used, which can reliably transmit torque while slidingly connecting with the connecting gear. When the position of the functional frame changes, the transmission path formed by the transmission chain between the transmission rod, the connecting gear and the transmission gear remains stable, ensuring continuous and effective power transmission from the self-propelled frame to the seeder, and avoiding the problem of transmission failure due to spacing adjustment. 3. By rotating the central rod, the sliding plate and rotating rod can be driven to move, which can drive the locking plates on both sides to separate or close synchronously, thereby quickly completing the locking and releasing of the functional frame. This centralized control operation method significantly simplifies the adjustment steps, saves time and effort, and greatly facilitates users to quickly adjust the sowing configuration in the field according to actual needs, improving the practicality and operational efficiency of the equipment.

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-6 This utility model provides a technical solution: a vegetable sowing device with adjustable spacing.

[0020] Example 1: This example discloses: a self-propelled power frame 1, a mounting frame 2 fixedly connected to the lower end of one side of the self-propelled power frame 1, positioning holes 3 evenly opened on the outer surface of the mounting frame 2, displacement wheels 4 fixedly installed on the outer surface of the mounting frame 2, and a sliding functional frame 5 installed on the outer surface of the mounting frame 2, a transmission rod 6 fixedly connected to the power output end of the self-propelled power frame 1, one end of the transmission rod 6 penetrating the outer surface of the functional frame 5, and a connecting gear 7 connected to the end of the transmission rod 6 penetrating the functional frame 5, a seeder 10 fixedly installed at one end of the functional frame 5, and a transmission gear 8 fixedly connected to the power input end of the seeder 10, and a transmission chain 9 connected between the transmission gear 8 and the connecting gear 7, and the connecting gear 7 being rotatably connected to the functional frame 5; The shaft section of the transmission rod 6 is hexagonal, and the transmission rod 6 and the connecting gear 7 are slidably connected. The self-propelled motor 1 provides power, which drives the entire device to move via the displacement wheel 4. The torque is transmitted through the hexagonal transmission rod 6 at its output end. The functional frame 5 is slidably mounted on the mounting frame 2. By sliding the functional frame 5, the lateral position of the seeder 10 fixed at one end can be changed, thereby adjusting the sowing row spacing. The transmission rod 6 is slidably connected to the connecting gear 7 on the functional frame 5. When the functional frame 5 moves, the connecting gear 7 moves accordingly and transmits power to the transmission gear 8 fixed at the power input end of the seeder 10 via the transmission chain 9. This design ensures that the power transmission from the self-propelled motor 1 to the seeder 10 remains connected and effective after the position of the seeder 10 is adjusted.

[0021] Example 2: This example is based on Example 1: A mounting plate 11 is provided on one side of the mounting frame 2, and the mounting plate 11 is fixedly installed to the mounting frame 2 by locking bolts 12. Locking plates 13 are engaged at the upper and lower ends of the mounting plate 11, and locking posts 14 are fixedly provided on the outer surface of the two locking plates 13 facing each other. A rotating center rod 15 is installed in the center of the outer surface of the mounting plate 11, and a sliding plate 16 is provided inside one end of the center rod 15. A rotating rod 17 is installed on one end of the sliding plate 16. A limit block 18 is fixedly provided on the outer surface of the mounting plate 11. The locking plate 13 is engaged with the positioning hole 3 via the locking pin 14, and the locking pin 14 is located on both sides of the locking bolt 12; The longitudinal section of the center rod 15 is T-shaped, and the center rod 15 and the sliding plate 16 are slidably connected. The sliding plate 16 and the rotating rod 17 are concentrically arranged, and the rotating rod 17 and the center rod 15 are clearance-fitted. A spring connects the sliding plate 16 and the center rod 15. The rotating rod 17 has a T-shaped design, and both ends of the rotating rod 17 are respectively attached to the opposite ends of the two locking plates 13; The upper and lower ends of the mounting plate 11 are engaged with locking plates 13, and locking pins 14 are fixed on the locking plates 13. In the locked state, the locking pins 14 will be engaged in the positioning holes 3 on the mounting bracket 2, thereby fixing the position of the functional bracket 5. When the row spacing needs to be adjusted, pull and rotate the rotating rod 17 in the center of the outer surface of the mounting plate 11, so that the rotating rod 17 disengages from the contact with the limiting block 18. The rotating rod 17 drives the sliding plate 16 inside the center rod 15 to slide and stretch the spring between the center rod 15. When the rotating rod 17 rotates, the two ends of the T-shape are respectively in contact with the upper and lower locking plates 13. Its movement will drive the two locking plates 13 to move synchronously in opposite directions, so that the locking pin 14 disengages from the positioning hole 3, thereby releasing the functional frame 5. After adjusting the position, rotate the center rod 15 in the opposite direction and press the locking plate 13, so that the locking pin 14 is inserted into the new positioning hole 3, and the locking is quickly completed. At this time, the rotating rod 17 will not rotate due to the obstruction of the limiting block 18 during the operation, causing the locking plate 13 to slide under pressure. The locking bolt 12 ensures that the mounting plate 11 remains stable in the installation of the functional frame 5.

[0022] 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.
