Description

Technical Field

[0001] The present invention relates to the technical field of seeders, and particularly to a liquid seeder. Background Art

[0002] Due to its unique geographical reasons, the climate in plateau areas is generally arid, and there are many challenges in agricultural production. The arid climate often causes problems such as shallow tillage layer, soil compaction, and many stones in the soil. Ordinary rotary tillers in the prior art are difficult to adapt to the above characteristics of the soil in plateau and arid areas. If a rotary tillage seeder is used to till the soil under such soil conditions, it is easy to damage the surface soil structure, which will further lead to insufficient tillage depth. And due to the arid climate and less precipitation, the overall water content of the soil is less. After rotary tillage, it is also easy to cause soil erosion, resulting in soil desertification, affecting seed germination and root growth. Moreover, the terrain is mountainous and rocky, increasing the difficulty of mechanical operation, and ordinary rotary tillage seeders are difficult to adapt. Therefore, it is urgent to develop a seeder that adapts to the environment of plateau and arid areas through technological innovation and improvement, which does not require tilling the soil and will not cause soil erosion, so as to improve agricultural production efficiency and crop yield.

[0022] In order to make the purpose, technical solutions and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments of the present invention. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] As Figures 1-5As shown in the figure, this embodiment discloses a liquid seeder, which includes a frame 1. An armrest frame is arranged on the frame 1. A front wheel axle system 8 and a rear wheel axle system 9 are arranged at the bottom of the frame 1. Both the front wheel axle system 8 and the rear wheel axle system 9 are composed of wheels and axles. The operator can drive the frame 1 to move by pushing the armrest frame. A control component 3, a fertilizing component 4, a seeding component 5 and an injection component 6 are arranged on the frame 1. The control component 3 can be installed on the armrest frame to facilitate the user to operate the control component 3 when pushing the frame 1 to move. The fertilizing component 4 contains a water-fertilizer mixture inside, and the seeding component 5 contains seeds to be sown inside. A pressurizing component 10 for pressurizing the inside is arranged on the fertilizing component 4. The pressurizing component 10 can be a booster pump. The control component 3 synchronously controls the opening and closing of the discharge ports of the fertilizing component 4 and the seeding component 5, and the control component 3 also controls the start and stop of the injection component 6. The discharge ports of the fertilizing component 4 and the seeding component 5 are connected to the inlet of the injection component 6 through a conveying component 7. Since the internal pressure of the fertilizing component 4 is relatively high, when the discharge ports of the fertilizing component 4 and the seeding component 5 are opened, the water-fertilizer mixture will spray out from the discharge port of the fertilizing component 4 and enter the conveying component 7. When the discharge port of the seeding component 5 is opened, the seeds will fall from the discharge port of the seeding component 5 into the conveying component 7 and mix with the water-fertilizer mixture therein, and then enter the injection component 6 through the conveying component 7. The injection component 6 starts to inject and injects the seeds into the soil.

[0025] The working principle and usage process of this embodiment:

[0026] When the user operates the liquid seeder disclosed in the present invention for seeding, first add the water-fertilizer mixture into the fertilizing component 4 and add seeds into the seeding component 5, then push the frame 1 to walk through the armrest frame. When reaching the seeding point, control the control component 3 to open the discharge ports of the fertilizing component 4 and the seeding component 5. The water-fertilizer mixture is sprayed into the conveying component 7 from the fertilizing component 4, and the seeds fall from the seeding component 5 into the conveying component 7. After the two are mixed at the conveying component 7, they will enter the inlet of the injection component 6. The control component 3 then controls the injection component 6 to work, injects the mixed seeds and the water-fertilizer mixture into the soil, and then closes the discharge ports of the fertilizing component 4 and the seeding component 5 through the control component 3 and controls the injection component 6 to stop, etc., and goes to the next seeding point.

[0027] Embodiment Two

[0028] As Figures 1-5As shown in the figure, this embodiment is developed on the basis of the above embodiment. Specifically, the control component 3 includes a handle 301, a first transmission wheel 302, a first connecting line 303, and a second transmission wheel 304. The first transmission wheel 302 and the second transmission wheel 304 are respectively arranged on the frame 1 through rotating shafts. The handle 301 is fixedly connected to the rotating shaft of the first transmission wheel 302. By rotating the handle 301, the rotating shaft of the first transmission wheel 302 can be driven to rotate, thereby driving the first transmission wheel 302 to rotate. One end of the first connecting line 303 is connected to the first transmission wheel 302, and the other end of the first connecting line 303 is respectively connected to the discharge port switches of the fertilizing component 4 and the seeding component 5 and the rotating shaft of the second transmission wheel 304. By rotating the handle 301 to drive the first transmission wheel 302 to rotate, the first connecting line 303 is tightened, and then the discharge port switches of the fertilizing component 4 and the seeding component 5 are driven to open. The fertilizing component 4 and the seeding component 5 respectively discharge the water and fertilizer mixture and seeds, which are transmitted to the injection component 6 through the conveying component 7. The second transmission wheel 304 is arranged above the injection component 6, and the second transmission wheel 304 is connected to the injection component 6 through a second connecting line 305. The tightening of the first connecting line 303 will also drive the second transmission wheel 304 to rotate, and the rotation of the second transmission wheel 304 will drive the second connecting line 305 to tighten, thereby driving the injection component 6 to move up and down to complete the injection work.

[0029] Embodiment III

[0030] As Figures 1-5 shown in the figure, this embodiment is developed on the basis of the above embodiment. Specifically, the fertilizing component 4 includes a box body 401, a liquid valve 408, a transmission shaft 406, a driven wheel 402, an impeller 403, a water stop ring 404, a safety valve 405, and a pressure gauge 407. The liquid valve 408 is arranged at the part where the conveying component 7 is connected to the discharge port of the box body 401. The opening and closing of the liquid valve 408 can control whether the fertilizing component 4 discharges materials. The pressure gauge 407 and the safety valve 405 are arranged on the box body 401. The pressure gauge 407 can detect the pressure value in the box body 401, and the safety valve 405 is used to relieve pressure when the pressure in the box body 401 is too high. The transmission shaft 406 is rotatably arranged on the box body 401 and passes through the side walls of the box body 401 at both ends. The impellers 403 are evenly distributed on the transmission shaft 406. The water stop ring 404 is arranged between the transmission shaft 406 and the side wall of the box body 401. The water stop ring 404 is used to prevent the water and fertilizer mixture in the box body 401 from leaking through the gap between the transmission shaft 406 and the side wall of the box body 401. The driven wheel 402 is arranged at both ends of the transmission shaft 406. A belt is wound around between the driven wheel 402 and the rear wheel shaft system 9. In this way, during the movement of the seeding machine, the rotation of the rear wheel shaft system 9 will drive the driven wheel 402 to rotate through the belt, and then drive the transmission shaft 406 to rotate, thereby driving the impeller 403 to rotate. The rotation of the impeller 403 enables the box body 401 to maintain pressure.

[0031] Example 4

[0032] As Figures 1-5 shown, this embodiment is developed on the basis of the above embodiment. Specifically, the sowing assembly 5 includes a sowing box 501 and a waterproof check valve 505. The waterproof check valve 505 is arranged at the part where the conveying assembly 7 is connected to the discharge port of the sowing box 501. The waterproof check valve 505 can prevent the water-fertilizer mixture sprayed from the discharge port of the fertilizing assembly 4 from entering the sowing box 501. A sowing roller 502 is arranged in the sowing box 501. First sprockets 503 are arranged at both ends of the sowing roller 502. A chain 504 is wound between the first sprockets 503 and the front wheel shaft system 8. Corresponding sprockets are also arranged at both ends of the wheel shaft of the front wheel shaft system 8. The front wheel shaft system 8 transmits rotation to the first sprockets 503 through the chain 504, and then drives the sowing roller 502 to rotate, so that the seeds in the sowing box 501 fall downward into the conveying assembly 7 and are mixed with the water-fertilizer mixture discharged from the injection and application assembly 6.

[0033] Example 5

[0034] As Figures 1-5 shown, this embodiment is developed on the basis of the above embodiment. Specifically, the injection and application assembly 6 includes an injection and application pipe 601, a counterweight sleeve 602, a fixed sleeve 603 and a compression spring 604. Seeds and the water-fertilizer mixture enter the inner wall through the feeding port at the upper end of the injection and application pipe 601 and are discharged from the discharge port at the bottom. An installation hole 2 is provided at the front end of the frame 1. The injection and application pipe 601 is arranged in the installation hole 2. The injection and application pipe 601 can slide up and down along the installation hole 2. The fixed sleeve 603 is fixedly connected to the outer side wall of the injection and application pipe 601. In order to ensure that the injection and application pipe 601 can slide vertically up and down, a guide rod can also be arranged between the frame 1 and the fixed sleeve 603. The fixed sleeve 603 is connected to the second connecting line 305. The counterweight sleeve 602 is arranged at the top of the injection and application pipe 601. The compression spring 604 is arranged between the fixed sleeve 603 and the frame 1. When the user rotates the handle 301 to tighten the first connecting line 303, it will drive the second driving wheel 304 to rotate, and then drive the second connecting line 305 to tighten. At the same time, due to the gravity of the counterweight sleeve 602, the fixed sleeve 603 is pulled downward, driving the injection and application pipe 601 to move downward and insert into the soil, injecting the seeds and the water-fertilizer mixture into the soil. After the work is completed, the user loosens the handle 301, and the compression spring 604 will push the fixed sleeve 603 upward due to its elasticity, thus driving the injection and application pipe 601 to move upward and reset.

[0035] Example 6

[0036] As Figures 1-5As shown, this embodiment is developed on the basis of the above embodiment. Specifically, the conveying assembly 7 includes a tee 701 and a hose 702. The tee 701 is respectively connected to the discharge ports of the fertilizing assembly 4 and the seeding assembly 5 and one end of the hose 702. The tee 701 is a metal pipe that can withstand the impact of the water-fertilizer mixture ejected from the fertilizing assembly 4. The other end of the hose 702 is connected to the inlet of the injection application assembly 6. The hose 702 has a flexible property and can bend so as to follow the movement of the injection application assembly 6.

[0037] The foregoing description of the embodiments enables those skilled in the art to practice or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Thus, the invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
