Description

Technical Field

[0001] This utility model relates to the field of seeders, and more specifically, to a handheld rapeseed seeder. Background Technology

[0002] Rapeseed sowing is a crucial step in the rapeseed cultivation process, and the correct sowing method directly impacts the growth and yield of rapeseed. A rapeseed seeder is an agricultural machine used to evenly sow rapeseed seeds into the soil. It is widely used in rapeseed cultivation, especially in modern agriculture, where it improves sowing efficiency and accuracy.

[0003] There are various types of seeders available, such as fully mechanized seeders and semi-automatic seeders. Semi-automatic seeders, such as handheld seeders, are mainly used for small-scale planting. Compared to purely manual seeding with transmission mechanisms, they are more labor-saving and efficient. Existing handheld seeders often only allow for single-row planting. During planting, the seeder opening is opened manually using levers, springs, etc., to allow the seeds to leak out. The entire seeder also needs to be lifted during use, resulting in low efficiency and fatigue after prolonged use. Utility Model Content

[0004] The purpose of this utility model is to provide a handheld rapeseed seeder to solve the technical problems existing in the background art.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0022] like Figures 1-5 As shown, this utility model provides a handheld rapeseed planter, including a handheld support 1, a mounting base 2 connected to the handheld support 1, and two sets of wheels 3 at the bottom of the mounting base 2. The mounting base 2 has several mounting slots 4 spaced apart, and a storage device 5 for storing rapeseed seeds is movably disposed within each slot 4. A switch structure 10 is movably disposed at the outlet of the storage device 5. Several actuating levers 15 are spaced apart circumferentially between the two sets of wheels 3. The two ends of each actuating lever 15 are fixed to the two sets of wheels 3 respectively. When the actuating lever 15 rotates to the switch structure 10, it actuates the switch structure 10 to open the outlet.

[0023] In the above scheme, rapeseed seeds are stored in a memory 5, which is installed in a mounting slot 4 on a mounting base 2. During sowing, the operator moves the entire seeder by pulling the hand-held support 1. During the movement, the traveling wheels 3 rotate, and the actuating rods 15 on them rotate synchronously. When the actuating rod 15 rotates to the switch structure 10, it pushes the switch structure 10 to rotate, thereby opening the closed discharge port. Rapeseed seeds flow out from the gap between the discharge port and the switch structure 10 and are sown in the soil. Several actuating rods 15 are provided. Each time the actuating rod 15 rotates to the switch structure 10, the discharge port opens once, thus achieving uniform seed distribution. This scheme can sow multiple rows of rapeseed seeds at once, resulting in high sowing efficiency. During sowing, there is no need for manual opening of the discharge port of the memory 5. The traveling wheels 3 cooperate with the switch structure 10 during movement to automatically open and close the discharge port, eliminating the need to lift the entire seeder, reducing operational difficulty, and saving time and effort.

[0024] Connecting rods 6 are provided on both sides of the memory 5. The connecting rods 6 pass through the mounting base 2 and are rotatably connected to the mounting base 2. Two clamping members 7 are also symmetrically arranged in the mounting groove 4, and the memory 5 is located between the two clamping members 7. The clamping member 7 includes a clamping plate 8 that fits against the outer wall of the memory 5 and a spring assembly 9 that is fixed at one end to the clamping plate 8 and at the other end to the mounting base 2. When clamped, the spring assembly 9 is in a compressed state.

[0025] In the above scheme, the memory 5 can rotate around the connecting rod 6 as a reference. A clamping member 7 holds the memory 5, and the spring assembly 9 is in a compressed state, which can position the memory 5 while ensuring that it rotates slightly within a certain range. This slight rotation of the memory 5 during material discharge ensures that the rapeseed seeds fall smoothly and avoids clogging the discharge port. The discharge port of the memory 5 is tilted at an angle of 10-15° to further ensure the smooth falling of the rapeseed seeds.

[0026] The switch structure 10 includes a mounting bracket 11, a switch plate 12 rotatably connected to the mounting bracket 11, and a toggle plate 13 fixed to the switch plate 12. A torsion spring structure 14 is provided at the connection between the switch plate 12 and the mounting bracket 11. In its natural state, the switch plate 12 is in abutting contact with the discharge port. The toggle plate 13 is located at the lowest point of the switch plate 12, and the angle between the toggle plate 13 and the horizontal plane is greater than the angle between the switch plate 12 and the horizontal plane.

[0027] In this design, four levers 15 are configured. When the traveling wheel 3 rotates, the four levers 15 rotate accordingly. When one of the levers 15 rotates to the position of the actuating plate 13, because the actuating plate 13 is tilted, the continued rotation of the lever 15 will push the actuating plate 13 to rotate, thereby causing the switch plate 12 to rotate at its connection with the mounting bracket 11, thus opening the discharge port. Figure 5 As shown. When the lever 15 rotates past the lever 13, the lever 13 is reset by the action of the torsion spring and continues to block the discharge port, thus achieving equal-distance material discharge.
