Description

Technical Field

[0001] This utility model belongs to the field of seeder technology, specifically relating to a grooved combined precision seeder. Background Technology

[0002] A seeder is a planting machine that sows crop seeds. Seeders are widely used in planting. Taking a flat-planting wheat seeder as an example, its structure consists of a frame, transmission device, seed and fertilizer box, seed metering device, fertilizer metering device, walking device, furrow opener, soil covering device, and compactor. Adjusting the speed of the seed metering shaft and the number of holes in the seeding disc can adjust the plant spacing of the seeder. That is, the faster the seed metering shaft speed, the smaller the plant spacing; conversely, the slower the speed, the larger the plant spacing. However, there are problems with the row spacing. Seeds may deviate during the process of falling from the seed metering device to the soil surface, and the seed depth may not reach the expected effect. Some seeds float on the soil surface, which affects the subsequent seed survival rate. Secondly, existing seeders only sow seeds, and fertilization needs to be done separately. Some seeders spread fertilizer and seeds at the same time, and some seeds may be eroded by fertilizer. Structurally, the overall machine structure is bulky and the center of gravity is unreasonable. Summary of the Invention

[0003] The purpose of this invention is to design a grooved combined precision seeder, which presses deep grooves into the seed path. On the one hand, it can control the spacing between each groove to achieve the seed sowing depth, reduce the situation where seeds float on the soil surface, and improve the seed survival rate. On the other hand, it adds a fertilization function, with fertilization and sowing set up separately, and the overall structure is coordinated and beautiful.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] The grooved combined precision seeder includes a seeder frame and a suspension frame. A fertilizer box is installed at the front of the frame, and several fertilizer applicators are set below the fertilizer box. A seed box is installed at the rear of the frame, and several seed applicators are set below the seed box. A seed delivery pipe is connected below the seed applicators. A gearbox is located below the fertilizer box. The gearbox drives the front rotary tiller shaft to rotate through a first set of universal joint transmission mechanisms. The gearbox drives the press wheel, the rear rotary tiller shaft, and the grooved shaft to rotate through a second set of universal joint transmission mechanisms. The grooved shaft is located in front of the seed delivery pipe, and the rear rotary tiller shaft and the press wheel are located behind the grooved shaft in sequence.

[0006] Furthermore, several protrusions are equidistantly arranged on the pressure groove shaft, and the protrusions are positioned in front of and behind the seed delivery tube, and are on the same straight line.

[0007] Furthermore, the first set of universal joint drive mechanisms transmits power to the front rotary tiller shaft through the front side box, and the second set of universal joint drive mechanisms transmits power to the press wheel, the rear rotary tiller shaft, and the pressing groove shaft through the rear side box.

[0008] Furthermore, the rear side box is equipped with a drive wheel connected to the second set of universal joint transmission mechanism. The drive wheel meshes with the first driven wheel, the first driven wheel meshes with the second driven wheel, the intermediate gear meshes with the second driven wheel, the pressure groove shaft gear and the rear rotary tiller shaft gear respectively, and the rear rotary tiller shaft gear meshes with the press wheel gear through the third driven gear.

[0009] Furthermore, a fertilizer guide plate is installed on the frame below the fertilizer dispenser.

[0010] Furthermore, the gearbox adopts a dual-output gearbox.

[0011] The above technical solution can achieve the following beneficial effects:

[0012] This utility model features a reasonable overall structural design and even weight distribution, making the machine more coordinated. More importantly, the front of the machine is for discharging fertilizer, while the rear is for sowing. After discharging fertilizer, the soil is tilled by the front rotary tiller, ensuring that the fertilizer is fully and evenly distributed into the soil. The seeds then fall through the seed delivery tube into the seed trough, which is compacted by the pressing shaft, effectively ensuring the row spacing and depth of the seeds. The soil covering wheel of the rear rotary tiller covers the seeds and compacts the soil, ensuring good contact between the seeds and the soil, which is beneficial for seed germination and growth.

[0013] The entire device can perform fertilization, rotary tillage, and sowing in one go, and can effectively ensure the row spacing and depth of the seeds, thus ensuring the seed survival rate.

[0014] The rear side box designed in this utility model can fully guarantee the operation of the press wheel, the rear rotary tiller shaft and the pressing shaft, and the addition of the pressing shaft will not increase the power output. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1-6 As shown, the grooving type combined precision seeder includes a seeder frame and a suspension frame. A fertilizer box 2 is installed at the front of the frame, and several fertilizer dispensers 4 are set below the fertilizer box 2. A fertilizer guide plate 21 is installed on the frame below the fertilizer dispensers 4. When the fertilizer is discharged from the fertilizer dispensers 4, it falls along the fertilizer guide plate 21 into the front of the front rotary tiller shaft. A double output gearbox 1 is installed in the middle below the fertilizer box 2. One output end of the double output gearbox 1 is connected to the first set of universal joint transmission mechanism. The first set of universal joint transmission mechanism transmits power to the front rotary tiller shaft 12 through the front side box. Rotary tillers are installed on the front rotary tiller shaft 12.

[0026] A seed box 3 is installed at the rear of the frame, and several seed metering devices 5 are set under the seed box 3. The seed delivery pipe 7 is connected to the bottom of the seed metering devices 5. Figure 1 Only one seed metering device is shown in the image. The other output end of the gearbox 1 is connected to the second set of universal joint transmission mechanism 9. The second set of universal joint transmission mechanism 9 transmits power to the press wheel 10, the rear rotary tiller shaft 11 and the grooving shaft 8 through the rear side box 6. The grooving shaft 8 is located in front of the seed delivery pipe 7, and several protrusions are evenly arranged on the grooving shaft 8. Figure 7 As shown), the protrusion and the seed delivery tube 7 are positioned front and rear and on the same straight line. Behind the pressing shaft 8 are the rear rotary tillage shaft 11 and the press wheel 10. The rear side box is equipped with a drive wheel 13 connected to the second set of universal shaft transmission mechanism 9. The drive wheel 13 meshes with the first driven wheel 15. The first driven wheel 15 meshes with the second driven wheel 14. The intermediate gear 17 meshes with the second driven wheel 14, the pressing shaft gear 16 and the rear rotary tillage shaft gear 19 respectively. The rear rotary tillage shaft gear 19 meshes with the press wheel gear 20 through the third driven gear 18.

[0027] Working principle:

[0028] The suspension frame is connected to the tractor's three-point suspension. The tractor's output power is connected to the gearbox. The tractor pulls the precision seeder forward and outputs power. The front fertilizer box 2 is filled with fertilizer, and the rear seed box 3 is filled with seeds. During operation, fertilizer is discharged from a series of fertilizer dispensers 4. The fertilizer falls into the soil along the fertilizer guide plate 21. Then, the power of the gearbox is transmitted to the front rotary tiller 12 through the first set of universal joint transmission mechanism and the front side box. The front rotary tiller 12 rotates, causing the rotary tiller blades to till the soil, pushing the fertilizer into the soil and also achieving the purpose of soil turning. Subsequently, the pressing shaft 8 presses on the tilled soil, forming several rows of seed grooves on the soil. The seed grooves are on the same vertical plane as the seed delivery pipe 7. In this way, the seeds can fall accurately into the seed grooves after passing through the seed metering device and the seed delivery pipe 7. The rear rotary tiller 11 then tills and covers the soil. Finally, the pressing wheel 10 compacts the soil, ensuring good contact between the seeds and the soil, which is conducive to seed germination and growth.

[0029] In the above embodiment, the gearbox transmits power to the rear side box through the second set of universal joint transmission mechanism 9. The structure inside the rear side box can ensure the normal operation of the press wheel 10, the rear rotary tillage shaft 11 and the pressing groove shaft 8.

[0030] The above descriptions are all preferred embodiments of this utility model. For those skilled in the art, any modifications to this utility model in various equivalent forms without departing from the principle of this utility model shall fall within the protection scope of the appended claims.
