Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to a pea seeder. BACKGROUND

[0002] As a populous country, China's demand for agricultural products is growing, and the decrease in agricultural labor and the aging trend intensify the urgent need to improve agricultural production efficiency and achieve modern agriculture.

[0003] Peas are not only a regular on the Chinese family dining table, but also have a long history in China's dietary history. Pea planting methods are relatively simple, and they prefer to grow in soil rich in organic matter and good drainage, and adapt well to sunny, cool, and humid environments. The most suitable soil is loose and fertile sandy loam. Peas can be planted by direct seeding or seedling transplanting. Direct seeding is to directly sow seeds in the soil with appropriate density, and then gently tamp after covering; seedling transplanting is to first grow seedlings in a seedling tray or seedling box, and then transplant them to the ground when the seedlings grow to a certain extent. Currently, pea seeding mainly relies on manual labor, and the agricultural production efficiency is low. Some large farms have introduced mechanical seeding methods, but mainly large general-purpose seeding machines.

[0004] However, the existing general-purpose seeding machines on the market have many problems in the process of pea seeding. Because the pea seeds are light and have requirements for soil moisture, the existing general-purpose seeding machines are prone to cause unstable seeding speed, high seed damage rate and other problems, which can easily cause sparse or dense seedling phenomenon during pea growth, affecting crop yield and quality. At the same time, since the row spacing and plant spacing of peas depend on the variety and cultivation method, generally, the row spacing can be maintained at about 30-40 cm, and the plant spacing can be determined according to the specific variety and growth conditions, generally can be maintained at about 5-10 cm. The general-purpose seeding machine has problems such as difficult adjustment of seeding distance and density, and is difficult to adapt to the seeding requirements of different varieties of peas. In addition, China's land resources are relatively limited, and the farmland area in many regions is small, so large machines are difficult to enter, and small seeding machines have strong land adaptability, can realize effective seeding in limited space, and are easier to maintain and store. Therefore, the development of small special-purpose pea automatic precision seeding machines is of great significance for promoting agricultural technological innovation and industrial upgrading in China.

[0005] Therefore, it is necessary to design a special-purpose small intelligent pea precision seeder for small-scale agricultural production, which can accurately control the spacing and quantity of pea seeds, solve the problems of existing seeding machines on the market such as large size, inconsistent seeding distance, high seed damage rate, etc., and improve its stability, adaptability and operation convenience, in order to improve the efficiency, yield and quality of pea seeding.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0062] like Figures 1-12 As shown, a pea planter includes a frame 2100 with a horizontal base plate 2800. A wheeled walking mechanism 2200 is located at the bottom of the frame 2100. The wheeled walking mechanism 2200 includes four wheels arranged in a rectangular pattern. At least one of the wheels is connected to a motor that drives it forward and backward. The forward or backward movement of the pea planter is achieved by rotating the motor in either direction. Preferably, the wheeled walking mechanism 2200 uses a front axle drive, with reduction motors and integrated tires on the left and right sides for propulsion. This design is simple to operate and has low cost.

[0063] Along the direction of travel of the frame 2100, a grooving mechanism, a sowing mechanism 2300, a fertilizing mechanism 2500, and a soil covering mechanism 2600 are arranged in sequence. As the pea planter moves forward, grooving, sowing, fertilizing, and soil covering are automatically completed.

[0064] The seeding mechanism 2300 includes a loading plate 2340, a seed storage trough 2310, a multi-group distribution device 2320, multiple four-way seed collection bins 2327, and multiple planting guide tubes 2330.

[0065] The loading plate 2340 is horizontally fixed above the base plate 2800. The seed storage trough 2310 is supported and fixed above the loading plate 2340 by multiple support legs. Multiple seed-leaking notches are provided at the bottom of the seed storage trough 2310, with four seed-leaking notches forming a group, corresponding to one pit. The multi-group distribution device 2320 is located above the loading plate 2340 and is arranged at equal intervals in the transverse direction. Each group distribution device 2320 includes four five-bladed centrifugal impellers 2322, four seeding sleeves 2321, and four seed-discharging tubes 2324. The seeding sleeves 2321 are cylindrical, with their upper ends fixed to the outer edge of the seed-leaking notches and their lower ends fixed to the loading plate 2340. The five-bladed centrifugal impellers 2322 are rotatably located inside the corresponding seeding sleeves 2321 and are connected to a seeding drive device that drives their rotation. The upper end of each seed-discharging tube 2324 is connected to the side wall of a seeding sleeve 2321. Multiple four-way seed collection bins 2327 are located below each distributing device 2320. The number of four-way seed collection bins 2327 corresponds to the number of rows sown at one time. The distance between two adjacent four-way seed collection bins 2327 is the row spacing. The figure shows the case of planting three rows of peas simultaneously. The four-way seed collection bins 2327 are fixed to the base plate 2800 and have four seed inlets on their side walls, which are connected to the lower ends of the corresponding seed dispensing pipes 2324. The upper end of each planting guide tube 2330 is connected to the bottom of a corresponding four-way seed collection bin 2327, and the lower end extends below the base plate 2800.

[0066] The grooving mechanism includes multiple grooving blades 2332, each grooving blade 2332 being fixed to the lower end of each row of seed tubes 2324. The grooving blades 2332 are located in front of the seed tubes 2324 and are plow-shaped, serving to loosen the soil and create trenches.

[0067] The planting guide tube 2330 includes an upper guide groove and a lower guide groove. The upper end of the upper guide groove is fixed and connected to the bottom of the four-way seed collection chamber 2327. The upper end of the lower guide groove is rotatably connected to the lower end of the upper guide groove and can be locked. The grooving knife 2332 is fixed to the lower end of the lower guide groove. By adjusting the height of the lower guide groove, the grooving depth of the grooving knife 2332 can be adjusted.

[0068] After trenching, sowing begins. Since peas require 3-4 seeds to fall into the same planting hole, four five-bladed centrifugal impellers 2322 are installed on each distribution device 2320. During sowing, pea seeds are first poured into the seed storage trough 2310. In each planting hole, seeds fall into four sowing sleeves 2321 through four seed-leaving notches. The five-bladed centrifugal impellers 2322 are driven by the sowing drive device to rotate, throwing the seeds in the sowing sleeves 2321 from the side into the seed discharge pipe 2324. The four seeds in the four sowing sleeves 2321 converge into a four-way seed collection bin 2327, and then are discharged into the planting hole through the planting guide tube 2330 at the bottom of the four-way seed collection bin 2327, completing the sowing process.

[0069] The five-bladed centrifugal impeller 2322 sows seeds five times per 360-degree rotation. By adjusting the rotation speed of the five-bladed centrifugal impeller 2322, the speed at which the seeds fall can be controlled, thereby adjusting the sowing spacing, improving sowing efficiency, and ensuring accurate seed positioning and stability.

[0070] Existing general-purpose seeders may have seed discharge holes that are too large or too small, or unstable movement of the seed metering device, which may damage pea seeds during the sowing process. However, the seed distribution device of this seeder has a replaceable seed distribution disc, which can precisely control the size of the seed discharge hole. At the same time, the five-bladed centrifugal wheel in the distribution device has smooth blades, which can effectively reduce the seed damage rate and reduce the possibility of clogging.

[0071] The sowing drive device includes one first rotating shaft 23284 and four second rotating shafts corresponding to each distributing device 2320. The middle part of the first rotating shaft 23284 is rotatably fixed to the loading plate 2340, with a first gear 2323 fixed at its upper end and a first synchronous pulley 23281 fixed at its lower end. The four second rotating shafts are arranged around the first rotating shaft 23284, with the lower end of each second rotating shaft rotatably fixed to the loading plate 2340. A five-bladed centrifugal impeller 2322 is fixed to one of the second rotating shafts, and a second gear meshing with the first gear 2323 is fixed on the second rotating shaft below the five-bladed centrifugal impeller 2322. The sowing drive device also includes a sowing drive motor 23285, fixed to the base plate 2800, with its motor shaft vertically upward and a second synchronous pulley fixed thereon. The second synchronous pulleys are connected to the multiple first synchronous pulleys 23281 via synchronous belt transmission.

[0072] By starting the seeding drive motor 23285, the second synchronous belt pulley rotates, which, under the linkage of the first synchronous belt, causes the first gear 2323 in each distribution device 2320 to rotate. Then, the first gear 2323 drives the remaining four second gears meshing with it to rotate, and the second gears drive the five-bladed centrifugal impeller 2322 on the second rotating shaft to rotate.

[0073] The fertilization mechanism 2500 includes a fertilizer storage tank 2510, multiple fixed chambers 2550, multiple fertilizer inlet trays 2530, and multiple fertilization pipes. The fertilizer storage tank 2510 is supported and fixed above a base plate 2800 by multiple legs, and has multiple fertilizer leakage openings. Multiple fixed chambers 2550 are fixed to the bottom of the fertilizer storage tank 2510, with their upper ends open and connected to a corresponding fertilizer leakage opening. A top plate is fixed above each fixed chamber 2550, and a lower fertilizer leakage port is provided on the top plate. Multiple fertilizer inlet trays 2530 are located above the top plate, each tray corresponding to a four-way seed collection chamber 2327. Each fertilizer inlet tray 2530 is rotatably fixed to a fertilizer leakage opening in each fertilizer storage tank 2510 and connected to a fertilization drive device that drives its rotation. Each fertilizer inlet tray 2530 has at least one upper fertilizer leakage port. The upper ends of multiple fertilizer pipes are fixed and connected to the lower fertilizer outlet, and their lower ends extend to the bottom plate 2800.

[0074] The fertilizer application pipeline includes a rigid fertilizer discharge pipe 2540 and a flexible fertilizer discharge pipe 2560. The upper end of the rigid fertilizer discharge pipe 2540 is fixed to the base plate 2800 of the frame 2100, and the lower end points to the ground. The upper end of the flexible fertilizer discharge pipe 2560 is fixed and connected to the lower fertilizer outlet, and the lower end extends into the rigid fertilizer discharge pipe 2540. The combination of the rigid pipe and the flexible pipe ensures smooth operation of the fertilizer application pipeline.

[0075] The fertilization drive device includes a third rotating shaft 2523 corresponding to each fertilizer feeding disc 2530. The middle part of the third rotating shaft 2523 is rotatably fixed to the top plate via bearings. A third synchronous pulley 2521 is fixed to the lower end of the third rotating shaft 2523, and the upper end is fixed to the fertilizer feeding disc 2530. The fertilization drive device also includes a fertilization motor 2524, which is fixed to the base plate 2800. Its motor shaft is vertically upward and has a fourth synchronous pulley fixed to it. The fourth synchronous pulley is connected to the multiple third synchronous pulleys 2521 via synchronous belt transmission. During fertilization, the fertilization motor 2524 starts, the fourth synchronous pulley rotates, and under the linkage of the second synchronous belt, each third rotating shaft 2523 drives the fertilizer feeding disc 2530 to rotate.

[0076] During fertilization, fertilizer is placed in the fertilizer storage tank 2510, and the fertilization drive device is activated to rotate the fertilizer inlet plate 2530. When the upper fertilizer outlet on the fertilizer inlet plate 2530 aligns with the lower fertilizer outlet on the top plate, the fertilizer falls into the fertilization pipe and finally into the soil, thus achieving the purpose of fertilization. As shown in the diagram, the fertilizer inlet plate 2530 has five upper fertilizer outlets. Because the fertilizer is irregularly shaped and the quantitative requirements are not high, this simple fertilizer inlet plate 2530 is used to spread about 10 fertilizer pellets. The fertilizer inlet plate 2530 fertilizes five times for every 360 degrees of rotation.

[0077] The soil covering mechanism 2600 includes a fixing plate and a soil covering plate 2610. The fixing plate is vertically located behind the frame 2100, and its upper end is fixed to the frame 2100. The upper end of the soil covering plate is hinged to the lower end of the fixing plate. The soil covering plate tilts backward, and as the frame 2100 moves forward, it will have a forward rotational force under its own weight, thereby covering the trench with soil and completing the soil covering operation. Preferably, the lower end of the soil covering plate is serrated, which can break up soil clods while covering the soil.

[0078] The frame 2100 is also equipped with a watering mechanism 2400, which is located between the sowing mechanism 2300 and the fertilization mechanism 2500. Watering is carried out after sowing and before fertilization to facilitate seed germination.

[0079] The water spraying mechanism 2400 includes a water storage bottle 2410, multiple water spray pipes 2460, and a water inlet pipe 2450. The water storage bottle 2410 is fixed to the frame 2100. Each water spray pipe 2460 is configured with a four-way seed collection bin 2327. The lower end of the water spray pipe 2460 extends to the bottom of the frame 2100. The water inlet pipe 2450 connects the upper end of the water spray pipe 2460 to the water storage bottle 2410. A water pump 2420 is installed on the water inlet pipe 2450. When spraying water, the water pump 2420 is turned on, and the water in the water storage bottle 2410 is distributed to each water spray pipe 2460 through the water inlet pipe 2450. Since each water spray pipe 2460 is configured with a four-way seed collection bin 2327, water can be sprayed onto the corresponding trenches, resulting in more precise spraying.

[0080] The above are merely preferred embodiments of the present invention. Any simple modifications, variations, and equivalent substitutions made by any person based on the content of the present invention shall fall within the protection scope of the present invention.
