Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an air-blown, full-field-returning no-till planter. Background Technology

[0002] Air-blowing seeders are a common type of automated seeding equipment that uses a fan to generate airflow to transport seeds into the seeder. To further improve seeding efficiency, most air-blowing seeders are also equipped with a fertilization function, thus achieving simultaneous seeding and fertilization. In existing technology, the fertilization structure of an air-blowing seeder mainly includes a fertilizer tank, which delivers fertilizer through a delivery pipe under gravity.

[0003] In practical applications, fertilizers are prone to caking due to moisture, which can clog the fertilizer application pipes and affect the fertilization effect. Air-blowing seeders, on the other hand, use fans only to transport seeds and do not directly act on the fertilizer, making it difficult to clear blockages. Furthermore, because fertilizer particles are much smaller than seeds, the airflow from the fan cannot be directly guided into the fertilizer box, easily causing fertilizer to scatter. Utility Model Content

[0004] To address the problem of easy clogging of fertilizer application pipes in existing technologies, this invention provides an air-blown, fully-returning no-till planter that avoids clogging of fertilizer application pipes and improves fertilization efficiency.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an air-blown full-return no-till seeder, including a frame, with multiple discharge ports at the bottom of the frame, a fertilizer box and a seed box fixedly installed on the frame, the fertilizer box and the seed box being connected to the discharge ports through several conveying components, a fan for blowing air into the seed box being installed on the seed box, and an anti-blocking component and a flow guiding component being installed at the top and bottom of the fertilizer box, the anti-blocking component including a filter plate movably installed in the fertilizer box, the filter plate having multiple holes for the fertilizer to pass through, the flow guiding component including a rectangular flow guiding plate, the flow guiding plate being inclinedly installed in the fertilizer box, and there is a distance between the flow guiding plate and one of the side walls of the fertilizer box to form a channel for the fertilizer to pass through;

[0006] The conveying assembly includes a conveying pipe and two connecting pipes. The two ends of the conveying pipe are connected to an installation pipe. The inner wall of the installation pipe is fixedly provided with several elastic protrusions. The outer wall of the connecting pipe is provided with several grooves corresponding to the elastic protrusions. The connecting pipe is connected to a fertilizer box, a seeding box or a discharge port.

[0007] As a further optimization of the utility model of an air-blown full-field no-till planter: several support blocks are fixedly installed on the inner wall of the fertilizer box, all of which are located on the same plane, and springs are fixedly connected to the support blocks, with the filter plate movably placed on the springs.

[0008] As a further optimization of the utility model of an air-blowing, full-field-returning no-till planter: a reinforcing frame is fixedly installed at the bottom of the filter plate. The reinforcing frame includes several first reinforcing rods and several second reinforcing rods, and the first reinforcing rods and the second reinforcing rods are vertically and fixedly connected.

[0009] As a further optimization of the utility model of an air-blown no-till planter, the guide plate and the fertilizer box are rotatably connected by multiple hinges, which are evenly distributed along the length of the guide plate.

[0010] As a further optimization of the utility model of an air-blown full-field no-till planter: a connecting plate is fixedly installed in the fertilizer box, and the connecting plate and the hinge are respectively located on two opposite side walls of the fertilizer box. A pad is fixedly connected to the connecting plate. The guide plate can fall on the pad during rotation, and when the guide plate falls on the pad, the upper surface of the guide plate is flush with the upper surface of the connecting plate.

[0011] As a further optimization of the utility model of an air-blown full-field no-till planter: a slide plate is fixedly connected to the guide plate near the edge of the channel, there is an angle between the slide plate and the guide plate, and the slide plate extends downward.

[0012] As a further optimization of the utility model of an air-blown full-field return no-till planter: connecting rings are fixedly installed on the guide plate and the fertilizer box respectively, and the two connecting rings are connected by a connecting rope.

[0013] As a further optimization of the utility model of an air-blown full-field return no-till planter: the fertilizer box includes an upper box and a lower box, the anti-blocking component and the flow guiding component are both set in the upper box, the width of the lower box gradually decreases along the vertical direction, and multiple discharge holes are opened at the bottom of the lower box.

[0014] As a further optimization of the utility model of an air-blown full-field return no-till planter: multiple partition plates are fixedly installed at the bottom of the lower box, and a discharge area is formed between two adjacent partition plates, and the discharge area is connected to the discharge hole.

[0015] As a further optimization of the utility model of an air-blown full-field return no-till planter: the discharge zone gradually decreases from top to bottom.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1) This utility model incorporates an anti-clogging component, which includes a filter plate movably mounted inside the fertilizer box. The filter plate has multiple holes for the fertilizer to pass through. The fertilizer falls through the holes to the top of the guide component and then slides down along the guide component. Clumps of fertilizer remain above the filter plate, preventing clogging. Furthermore, in farmland where the terrain is uneven, the filter plate inside the fertilizer box shakes as the tractor pulls the fertilizer box, which helps to break down clumps of fertilizer to some extent.

[0018] 2) By setting up a flow guiding component, which includes a rectangular flow guiding plate, the fertilizer is prone to accumulating and clogging in the conveying component or the discharge port when it falls directly through the conveying component. Therefore, the flow guiding plate is inclinedly set in the fertilizer box, and there is a distance between the flow guiding plate and one of the side walls of the fertilizer box to form a channel for the fertilizer to pass through. When the fertilizer falls, it first hits the flow guiding plate, and then slowly slides down the flow guiding plate and flows down the channel, further avoiding fertilizer blockage.

[0019] 3) This utility model features a conveying assembly including a conveying pipe and two connecting pipes. The two ends of the conveying pipe are connected to an installation pipe. The inner wall of the installation pipe is fixedly provided with several elastic protrusions, and the outer wall of the connecting pipe has several grooves corresponding to the elastic protrusions. The connecting pipes are connected to a fertilizer box, a seeding box, or a discharge port. By pushing the elastic protrusions on the installation pipe into the corresponding grooves on the connecting pipe, the connection between the installation pipe and the connecting pipe can be quickly achieved.

[0027] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as how the seeding box 3 cooperates with the fan 4, how the fertilizer box 2 and the seeding box 3 are fixed on the frame 1, the material of the elastic protrusion 22, the structure of the hinge 11, etc.

[0028] Example 1

[0029] A type of air-blown no-till planter, such as Figures 1 to 3 As shown, the machine includes a frame 1 with multiple discharge ports at the bottom. A fertilizer box 2 and a seeding box 3 are fixedly mounted on the frame 1. Both the fertilizer box 2 and the seeding box 3 are connected to the discharge ports through several conveying components. The seeding box 3 is equipped with a fan 4 for blowing air into the seeding box 3. Since the seeds are not easy to clump together and the fan 4 works in conjunction with the seeding box 3, the seeding box 3 is less likely to be blocked. Therefore, anti-blocking components and flow guiding components are only installed at the top and bottom of the fertilizer box 2.

[0030] The anti-clogging component includes a filter plate 15 movably mounted inside the fertilizer box 2. The filter plate 15 has multiple perforations 16 for the fertilizer to pass through. The fertilizer falls through the perforations 16 to the top of the guide assembly, and then slides down along the guide assembly. Clumps of fertilizer remain above the filter plate 15, preventing clogging. Furthermore, since fertilization is carried out on uneven farmland, the filter plate 15 inside the fertilizer box 2 will shake as the tractor pulls the fertilizer box 2, which can break up clumps of fertilizer to some extent.

[0031] The flow guiding component includes a rectangular flow guiding plate 10. When fertilizer falls directly through the conveying component and flows out of the discharge port, it is easy to accumulate and block in the conveying component or the discharge port. Therefore, the flow guiding plate 10 is inclinedly set in the fertilizer box 2, and there is a distance between the flow guiding plate 10 and one of the side walls of the fertilizer box 2 to form a channel 20 for fertilizer to pass through. When the fertilizer falls, it first hits the flow guiding plate 10, and then slowly slides down the flow guiding plate 10 and flows down along the channel 20.

[0032] The conveying assembly includes a conveying pipe 5 and two connecting pipes 6. Both ends of the conveying pipe 5 are connected to an installation pipe 21. The inner wall of the installation pipe 21 is fixedly provided with several elastic protrusions 22. The outer wall of the connecting pipe 6 has several grooves corresponding to the elastic protrusions 22. The connecting pipe 6 is connected to a fertilizer box 2, a seeding box 3, or a discharge port. By pushing the elastic protrusions 22 on the installation pipe 21 into the corresponding grooves on the connecting pipe 6, the connection between the installation pipe 21 and the connecting pipe 6 can be quickly achieved. To facilitate adjustment of the length of the conveying pipe 5, the conveying pipe 5 can be configured as a corrugated pipe.

[0033] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0034] Example 2

[0035] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 and Figure 4 As shown, fertilization is carried out on uneven farmland. During the fertilization process, the filter plate 15 inside the fertilizer box 2 will sway as the tractor pulls the fertilizer box 2. Several support blocks 18 are fixedly installed on the inner wall of the fertilizer box 2. All support blocks 18 are located on the same plane, and springs 19 are fixedly connected to the support blocks 18. The filter plate 15 is movably placed on the springs 19. Under the action of the springs 19, in addition to swaying due to the terrain, the filter plate 15 will also sway further due to the presence of the springs 19. This swaying will cause the clumps of fertilizer to decompose on their own, allowing the fertilizer to fall through the drain hole 16.

Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 6 As shown, to ensure the service life of the filter plate 15, a reinforcing frame is fixedly installed at the bottom of the filter plate 15. The reinforcing frame includes several first reinforcing rods 17 and several second reinforcing rods 27, which are vertically fixedly connected. The first reinforcing rods are fixedly connected to the filter plate 15, and the second reinforcing rods are fixedly installed on the first reinforcing rods, which facilitates the processing of the first and second reinforcing rods.

A pad 14 is fixedly connected to the connecting plate 13, so that the guide plate 10 can fall on the pad 14 during rotation, and when the guide plate 10 falls on the pad 14, the upper surface of the guide plate 10 is flush with the upper surface of the connecting plate 13. If the upper surface of the guide plate 10 is not flush with the connecting plate 13, fertilizer will accumulate.

[0046] Example 8

[0047] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 and Figure 5As shown, the fertilizer box 2 includes an upper box 8 and a lower box 9. The anti-blocking component and the flow guiding component are both located inside the upper box 8. The width of the lower box 9 gradually decreases along the vertical direction. Multiple discharge holes 26 are provided at the bottom of the lower box 9, and these discharge holes 26 can be connected to a transition shell 7. The lower box 9 can guide the fertilizer passing through it, allowing it to flow out of the discharge holes 26 more effectively. The connection between the connecting pipe 6 and the discharge holes 26 is conventional prior art and will not be described in detail here.

[0048] To prevent fertilizer from accumulating at the bottom of the lower housing 9, multiple partition plates 25 are fixedly installed at the bottom of the lower housing 9. A discharge area is formed between two adjacent partition plates 25, and the discharge area is connected to the discharge hole 26.
