Description

Technical Field

[0001] This utility model relates to the field of seeder technology, and in particular to a multi-row synchronous seeding component for a rotary tillage and fertilization seeder. Background Technology

[0002] A seeder is a planting machine specifically designed for crop seeds. Depending on the type of crop being sown, it is often named a grain row seeder, corn hill seeder, cotton seeder, or pasture broadcaster, etc. Seeders are suitable for sowing crop seeds or pelleted coated seeds. Based on the sowing method, they can be further divided into three main categories: broadcast seeders, row seeders, and hill seeders. With technological advancements, various precision seeders have become widely used. These devices can precisely control the seeding rate, spacing between hills (plants), and sowing depth, significantly improving the accuracy and efficiency of sowing.

[0003] For example, the fertilizing rotary tillage seeder disclosed in the prior art with the number CN220986618U has a protective frame and a detachable seeding tube installed on the protective frame. Although the protective frame and the seeding tube can protect the seeding tube during use and facilitate the adjustment of the seeding spacing, the seeding tube lacks a structure to force the seeds out. As a result, if the outlet end of the seeding tube becomes blocked during the seeding process, effective seeding cannot be achieved, thus reducing the seeding quality.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a multi-row synchronous sowing component for a rotary tillage and fertilization seeder to solve the aforementioned technical defects. This invention uses a square rod to carry multiple bulldozer blades in synchronous reciprocating motion. On the one hand, it causes the seed-pushing rod to move inside the auxiliary seed-pushing tube, thereby forcibly pushing out the seeds inside the auxiliary seed-pushing tube and achieving multi-row synchronous sowing while avoiding the problem of blockage at the port of the auxiliary seed-pushing tube preventing sowing. On the other hand, the bulldozer blades create sowing grooves to prevent soil from causing resistance to the movement of the auxiliary seed-pushing tube, thus extending the service life of the sowing tube.

[0006] This can be achieved through the following technical solutions:

[0007] A multi-row synchronous sowing component for a rotary tillage and fertilization seeder includes a mounting frame. Multiple adjusting seats are movably mounted inside the mounting frame, and slide rails that are slidably connected to the adjusting seats are bolted to the inner walls on both sides of the mounting frame. A sowing tube is fixedly connected to the adjusting seat, and an auxiliary pushing tube that is perpendicularly arranged to the bottom of the sowing tube is fixedly connected to it. A pushing rod that is adapted to the auxiliary pushing tube slides inside the auxiliary pushing tube, and a bulldozer blade is fixedly connected to one end of the pushing rod.

[0008] Preferably, the bottom of the auxiliary seed-pushing tube is fixedly connected to a soil-inserting blade, and the seed-planting tube is connected to the seed delivery tube of the rotary tillage and fertilization seeder.

[0009] Preferably, the mounting frame is internally fixedly connected to a fixing rod that is slidably connected to the adjusting seat, and the top of the fixing rod is provided with a plurality of fixing holes at equal intervals along its length direction, and the adjusting seat is threadedly connected with fixing bolts that are compatible with the fixing holes.

[0010] Preferably, a U-shaped frame is fixedly connected to one side of the mounting frame, and a square rod is provided inside the U-shaped frame. A movable sleeve that is slidably connected to the top of the bulldozer blade is fixedly connected to the top of the square rod.

[0011] Preferably, the two ends of the square rod are fixedly connected to a movable sleeve slidably connected to a U-shaped frame, and the two sides of the U-shaped frame are rotatably connected to a reciprocating screw threadedly connected to the corresponding movable sleeve. A motor for driving the corresponding reciprocating screw to rotate is bolted on the U-shaped frame.

[0012] Preferably, the top two sides of the mounting frame are symmetrically welded with support plates, and the top of the support plates is welded with a connecting plate, which has multiple connecting holes.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention first uses multiple adjusting blocks that are movable within the mounting frame to adjust the sowing spacing. Then, a square rod carries multiple bulldozer blades that reciprocate synchronously. On one hand, this causes the pushing rod to reciprocate within the auxiliary pushing tube, forcibly pushing out the seeds that have entered the tube, achieving multi-row synchronous sowing while effectively preventing blockage at the tube's end, which would hinder effective sowing. On the other hand, the rapid reciprocating motion of the bulldozer blades creates sowing troughs, avoiding resistance from soil during the tube's movement, thus effectively extending the tube's lifespan.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Example 1: Please refer to Figure 1 - Figure 6 As shown, the problem of ineffective sowing caused by the lack of a structure to force the seeds to be pushed out in the existing technology, which leads to blockage of the sowing tube, can be solved by the following solution;

[0027] This embodiment of a multi-row synchronous sowing component for a rotary tillage and fertilization seeder includes a mounting frame 1. Multiple adjusting seats 2 are movably installed inside the mounting frame 1. By movably installing the adjusting seats 2, the distance between two adjacent sowing tubes 21 can be adjusted, thereby adjusting the sowing spacing. Slide rails that are slidably connected to the adjusting seats 2 are bolted on the inner walls on both sides of the mounting frame 1 for stable sliding installation of the adjusting seats 2 within the mounting frame 1, thereby improving the convenience of adjusting the sowing spacing.

[0028] The adjusting seat 2 is fixedly connected to the sowing tube 21, and the bottom of the sowing tube 21 is fixedly connected to the auxiliary pushing tube 22 which is perpendicular to it. The auxiliary pushing tube 22 has a matching pushing rod 23 sliding inside it. After the seeds in the sowing tube 21 enter the auxiliary pushing tube 22, the seeds in the auxiliary pushing tube 22 are forced out by the sliding of the pushing rod 23 inside the auxiliary pushing tube 22. This allows the auxiliary pushing tube 22 to be cleared by itself when the port is blocked by soil, thereby achieving the effect of effective sowing.

[0029] One end of the seed pusher 23 is fixedly connected to a bulldozer blade 24. The rapid reciprocating motion of the bulldozer blade 24 opens the seeding trough, which can effectively avoid the resistance caused by the soil to the auxiliary seed pusher 21 during the movement of the auxiliary seed pusher 21, thereby effectively extending the service life of the seed pusher 21 during the sowing and movement process.

[0030] The bottom of the auxiliary seed pusher tube 22 is fixedly connected to the soil entry blade 25, which causes the rotary tillage fertilizer seeder to move downward with the mounting frame 1. This reduces the soil entry resistance of the auxiliary seed pusher tube 22 during the process of entering the soil, thereby improving the protection effect on the seed tube 21 and the auxiliary seed pusher tube 22 during soil entry. The seed tube 21 is connected to the seed delivery tube 26 of the rotary tillage fertilizer seeder, so that the seeds in the rotary tillage fertilizer seeder can smoothly and quantitatively enter the seed tube 21 and then fall into the corresponding auxiliary seed pusher tube 22.

[0031] The mounting frame 1 is internally fixedly connected to a fixing rod 11 that is slidably connected to the adjusting seat 2. The top of the fixing rod 11 is provided with a number of fixing holes 12 at equal intervals along its length. The adjusting seat 2 is threadedly connected with fixing bolts that are compatible with the fixing holes 12. By using the number of fixing holes 12 on the fixing rod 11 and the fixing bolts on the adjusting seat 2, the position of the adjusting seat 2 can be fixed. The number of fixing holes 12 is greater than the number of adjusting seats 2, thereby achieving the fixing of the position of the adjusting seat 2 at different intervals.

[0032] A U-shaped frame 13 is fixedly connected to one side of the mounting frame 1 for the movable installation of the square rod 14. The square rod 14 is installed inside the U-shaped frame 13. The top of the bulldozer blade 24 is fixedly connected to a movable sleeve 27 that is slidably connected to the square rod 14. Through the sliding connection between the movable sleeve 27 on the bulldozer blade 24 and the square rod 14, interference with the position movement of the adjusting seat 2 can be avoided. The square structure of the cross section of the square rod 14 can enhance the horizontal sliding effect of carrying the seed pushing rod 23 in the auxiliary seed pushing tube 22.

[0033] The square rod 14 is fixedly connected to the two ends of the U-shaped frame 13 and the movable sleeve 15 is slidably connected to it, which is used to realize the movable installation of the square rod 14 in the U-shaped frame 13. The two sides of the U-shaped frame 13 are rotatably connected to the reciprocating screw 16 that is threadedly connected to the corresponding movable sleeve 15. The U-shaped frame 13 is bolted with a motor 17 that drives the corresponding reciprocating screw 16 to rotate.

[0034] Two sets of ear plates are welded onto the U-shaped frame 13 and rotatably connected to the reciprocating screw 16. The motor 17 is installed on the corresponding ear plates. The motor 17 drives the reciprocating screw 16 to rotate, causing the square rod 14 to reciprocate. Setting two sets of reciprocating screws 16 can further strengthen the force of the reciprocating motion of the square rod 14 and improve the opening effect of the bulldozer blade 24 on the seeding trough.

[0035] The top two sides of the mounting frame 1 are symmetrically welded with support plates, and the top of the support plates is welded with connecting plates. Multiple connecting holes are provided on the connecting plates, which are used to connect the mounting frame 1 with the rotary tillage fertilizer seeder.

[0036] The working process and principle of this utility model are as follows:

[0037] During use, the seeds in the rotary tillage and fertilization seeder are quantitatively fed into several seeding tubes 21 through the corresponding seed delivery tube 26, and then fall into the corresponding auxiliary seed pushing tube 22. The motor 17 drives the reciprocating screw 16 to rotate, and the reciprocating screw 16 drives the square rod 14 to reciprocate. The square rod 14 causes multiple bulldozer blades 24 to reciprocate synchronously through the movable sleeve 15. Combined with the movement of the rotary tillage and fertilization seeder carrying the mounting frame 1, the seeding trough is opened to reduce the movement resistance of the auxiliary seed pushing tube 22.

[0038] The bulldozer blade 24, carrying the seed-pushing rod 23, slides inside the auxiliary seed-pushing tube 22, forcibly pushing out the seeds inside the auxiliary seed-pushing tube 22 to achieve the purpose of simultaneous sowing of multiple rows. When the port of the auxiliary seed-pushing tube 22 is blocked by soil, the auxiliary seed-pushing tube 22 is cleared simultaneously to enable effective sowing.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
