Description

TECHNICAL FIELD

[0002] The rice dry seeding planter is an agricultural mechanical equipment for directly seeding rice in dry land. Compared with the traditional paddy field planting method, the rice dry seeding saves water resources and effectively improves the efficiency and adaptability of rice planting by seeding in dry land without irrigation, which has a wide application prospect, especially in areas with water shortage or low requirements for paddy fields.

[0003] Chinese patent document (publication number: CN208540412U) discloses a ditching and ditching integrated rice dry seeding planter. The planter includes multiple functional modules, such as a fertilizing and ditching disc, a ditching wheel, a covering disc, a fertilizer outlet pipe, a seed metering device, and a seed conveying pipe, etc. When the planter is working, it first opens a ditch and applies fertilizer on the land through the fertilizing and ditching disc, then the ditching wheel presses a ditch with consistent depth on the land, the seed conveying pipe discharges seeds into the ditch, and the covering disc performs covering treatment, completing the seeding of rice seeds.

[0004] However, the existing seed metering device is usually connected with only one seed conveying pipe. This design cannot meet the actual planting requirements in fields with high planting density, especially in the case of fertile land or rice varieties with high demand for intensive planting.

[0035] The main frame 1 of the rice dry seeding machine is connected to the agricultural power equipment, the agricultural power equipment is started in the farmland to drive the main frame 1 to move. The fertilizing opening disc firstly opens a groove in the farmland, and uniformly releases the fertilizer in the fertilizer box 3 into the groove; the plurality of furrow pressing wheels 41 press the seeding furrows with the same depth in the farmland; the driving wheel 2 is rotated along with the starting of the agricultural power equipment, and drives the seed sowing device 421 through the chain set 5, so that the plurality of seed discharging ports 4233 of the seeding assembly 42 respectively scatter seeds into the plurality of seeding furrows. Then, the plurality of covering discs 43 uniformly cover the seeds in the seeding furrows, and the seeding is completed. Compared with the prior art, the application can simultaneously perform the seeding operation of the plurality of seeding furrows on the same seeding unit 4, and the seeding efficiency is improved, especially in the field requiring large planting density.

[0036] It should be noted that the driving wheel 2, the fertilizing opening disc, the furrow pressing wheel 41 and the covering disc 43 are prior arts, and will not be repeated here; the fertilizing opening disc is located on the extension line between the two adjacent furrow pressing wheels 41, and releases the fertilizer between the two rows of seeding furrows; the chain set 5 is also a prior art, and the chain set 5 comprises a plurality of chain links which are sequentially connected in transmission, and the rotation of the driving wheel 2 (two) can be sequentially transmitted to the plurality of seed sowing devices 421 through the plurality of chain links.

[0037] The application discloses a rice dry seeding machine Figures 3-11 The two seed discharging ports 4233 are shown.

[0038] The agricultural power equipment includes common agricultural machines such as tractors; before sowing, the field needs to be processed by a rotary cultivator to make the land soft, so that the furrow roller 41 can press the sowing furrows with consistent depth.

[0039] Reference Figures 4-6 The seeder 421 comprises a seeding shell 4211, a plurality of seeding discs 4212 rotationally connected to the inner cavity of the seeding shell 4211, and a limiting brush 4214 connected to the inner cavity of the seeding shell 4211. The disc surfaces of the plurality of seeding discs 4212 are aligned and abutted, and the plurality of seeding discs 4212 are rotationally connected by the same rotating shaft 4213, one end of the rotating shaft 4213 protrudes out of the seeding shell 4211, and the protruding end is connected to one end of the chain set 5 away from the driving wheel 2. The plurality of seeding discs 4212 form a disc set, and the disc set separates the inner cavity of the seeding shell 4211 into a first seed storage cavity 4215 and a seeding cavity 4216. The edge arc surface of the seeding disc 4212 is uniformly provided with a plurality of seed grooves 4212a for embedding seeds along the circumferential direction of the seeding disc 4212. The size of the seed groove 4212a is matched with the size of a single seed. The limiting brush 4214 is located in the first seed storage cavity 4215 and abuts against the edge arc surface of the plurality of seeding discs 4212 to prevent the seeds outside the seed groove 4212a that has embedded a seed from entering the seeding cavity 4216 along with the rotation of the seeding disc 4212.

[0040] The seed storage box 422 has a second seed storage cavity 4221 communicating with the first seed storage cavity 4215, and a plurality of seed discharge ports 4233 of the seed discharge member 423 communicate with the seeding cavity 4216, and the plurality of seed discharge ports 4233 correspond to the plurality of seeding discs 4212 one by one.

[0041] The driving wheel 2 drives the rotating shaft 4213 to rotate through the chain set 5, thereby driving the plurality of seeding discs 4212 to rotate coaxially. The seeds stored in the second seed storage cavity 4221 of the seed storage box 422 enter the first seed storage cavity 4215 under the action of gravity, and part of the seeds are embedded into the seed groove 4212a of the seeding disc 4212. With the rotation of the seeding disc 4212, the seeds embedded in the seed groove 4212a are driven to enter the seeding cavity 4216. The seeding cavity 4216 is located at the bottom of the seeder 421, and the seeds are discharged from the seed groove 4212a under the action of gravity and enter the plurality of seed discharge ports 4233, and finally are discharged into the sowing furrow. The limiting brush 4214 abuts against the edge of the seeding disc 4212 to prevent the seeds that have not entered the seed groove 4212a from entering the seeding cavity 4216 along with the rotation of the seeding disc 4212, thereby ensuring single-seed sowing in the sowing process and avoiding seed waste and uneven planting caused by multiple-seed sowing. The present application realizes the cooperative work of the plurality of seeding discs 4212 through the same seeder 421, and realizes efficient and uniform sowing through the plurality of seed discharge ports 4233.

[0042] It should be noted that the through end of the rotating shaft 4213 can be provided with a sprocket matched with the chain of the chain set 5.

[0043] Reference Figures 6-10 The edge arc surface of the seeding disc 4212 is provided with a plurality of seed slots 4212a in sequence along the circumferential direction of the edge arc surface, and the seeding disc 4212 is connected with a plurality of seed pushing members 4217 on the cavity wall of the seeding cavity 4216. One end of the seed pushing member 4217 extends into the seed pushing slot 4212b, so that the seed in the seed pushing slot 4212b is pushed out of the seed slot 4212a and enters the seed outlet 4233. The plurality of seed pushing members 4217 and the plurality of seed pushing slots 4212b correspond one by one.

[0044] Some seeds may be irregular in shape or large in size, and after being embedded in the seed slot 4212a, they cannot automatically fall out of the seed slot 4212a and enter the seed outlet 4233 when they reach the seeding cavity 4216. When the seed continues to rotate with the seeding disc 4212, the seed in the seed pushing slot 4212b is pushed out of the seed slot 4212a by one end of the seed pushing member 4217, thereby entering the seed outlet 4233, avoiding the problem that the seed is always blocked in the seed slot 4212a, and ensuring the smoothness and efficiency of the seeding process. The seed pushing slot 4212b sequentially connects all the seed slots 4212a on the edge arc surface, avoiding the seed pushing member 4217 directly abutting against the slot wall of the seed slot 4212a.

[0045] The cavity wall of the seeding cavity 4216 is connected with two limiting rods 4218, and the plurality of seed pushing members 4217 are sleeved on the two limiting rods 4218. The side of the seed pushing member 4217 away from the limiting rod 4218 forms an arc-shaped edge matched with the seeding disc 4212, and the arc-shaped edge is located in the seed pushing slot 4212b. The two limiting rods 4218 can avoid the self-rotation of the seed pushing member 4217.

[0046] Reference Figure 11 The seed outlet 4233 includes a connecting portion 4231 detachably connected to the seeder 421, a plurality of seed outlet branch portions 4232 connected to the connecting portion 4231, the connecting portion 4231 having a seed outlet through hole 4233a communicating with the seeding cavity 4216, the seed outlet branch portion 4232 having a seed outlet branch hole 4233b communicating with the seed outlet through hole 4233a, the plurality of seed outlet branch holes 4233b and the seed outlet through hole 4233a forming a plurality of seed outlets 4233, and the plurality of seed outlet branch portions 4232 and the plurality of seeding discs 4212 corresponding one by one.

[0047] The seed distribution fork 4232 is just below the seeding disc 4212, so that after the seed is separated from the seeding cavity 4216, it can automatically fall into the seed distribution fork 4232. The seed distribution fork 4232 is in an inclined state as a whole, and the spacing between the ends of the plurality of seed distribution forks 4232 away from the connecting part 4231 (the inclination angle of the seed distribution fork 4232) can be adjusted according to the required row spacing. This design allows the seed to naturally fall into the seed distribution fork 4232 under the action of gravity and be guided into the seeding trench through the inclined seed distribution fork 4232. By adjusting the inclination angle of the seed distribution fork 4232, the requirements of different fields for planting row spacing can be met.

[0048] The limiting brush 4214 is a flexible member abutting against the arc-shaped edge of the seeding disc 4212, which can avoid damage to the seed caused by rigid contact and prevent excess seeds from entering the seeding cavity 4216.

[0049] The main frame 1 is connected with a movable four-bar linkage (not shown in the figure), the plurality of furrow wheels 41 are connected to the movable four-bar linkage through a first connecting member, the seeder 421 is connected to the movable four-bar linkage, and the plurality of covering discs 43 are connected to the side of the seeder 421 away from the movable four-bar linkage through a second connecting member.

[0050] The four connecting rods of the movable four-bar linkage are connected through movable shafts, so that the movable four-bar linkage can adaptively deform. When encountering uneven terrain, the movable four-bar linkage can adjust the positions of the furrow wheels 41, the seeder 421, and the covering discs 43 accordingly, so that each functional module can better fit the terrain and adapt to complex farmland environments.

[0051] In some embodiments, for some flat farmland, the plurality of furrow wheels 41 and the seeder 421 can also be fixedly connected to the main frame 1.

[0052] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradictions). In order to make the description simple, not all possible combinations of the technical features in the above embodiments are described. These embodiments not explicitly written should also be considered as falling within the scope of the present disclosure.

[0053] The above has described the present application in more detail and in a specific manner through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, some conventional adjustments or further innovations can also be made to these specific embodiments; however, as long as these conventional adjustments or further innovations do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
